Publication No. 3-34353

Generally, pantograph jacks require high strength to jack up vehicles, and the higher the strength, the heavier the weight becomes. Therefore, the jack holding structure is also required to have strength, and if the plate thickness of the support bracket is increased to increase strength as in Patent Document 1, there is a problem that the jack holding structure becomes larger and heavier.

The present invention aims to solve the above-mentioned problems.

An aspect of the present invention is a jack holding structure that is mounted on a vehicle and holds a pantograph jack, and includes a holding bracket formed from a plate material and fixed to the body of the vehicle, and a holding member that is fixed to the holding bracket and holds the pantograph jack on one side of the holding bracket in the plate thickness direction, the holding bracket having an upper bracket and a lower bracket arranged in the vehicle height direction, an upper part of the lower bracket and a lower part of the upper bracket overlap in the plate thickness direction in the vehicle height direction, and have overlapping portions that are connected to each other in the plate thickness direction.

According to the present invention, the thickness of the holding bracket is increased in the plate thickness direction by the overlapping portion, thereby suppressing an increase in the weight of the holding bracket and increasing its strength. As a result, when the pantograph jack is held by the holding bracket, the load of the pantograph jack can be effectively received by the overlapping portion.

FIG. 1 is an explanatory diagram showing a rear part of a vehicle equipped with a jack holding structure according to an embodiment of the present invention. FIG. 2 is an overall front view of the jack holding structure shown in FIG. FIG. 3 is a cross-sectional view taken along line III-III in FIG. FIG. 4 is an enlarged view showing the jack holding structure and its periphery in FIG.

As shown in FIG. 1, the jack holding structure 10 according to this embodiment is mounted on, for example, a vehicle 12 and holds a pantograph jack P. When, for example, changing a tire on the vehicle 12, the pantograph jack P can be placed on the road surface G or the like below the vehicle 12 to jack up the vehicle 12.

The jack holding structure 10 is provided on the vehicle body 14 of the vehicle 12. The vehicle body 14 has a passenger compartment 16. A seat 18 for a passenger to sit on is provided in the front part of the passenger compartment 16 in the longitudinal direction of the vehicle body 14. A luggage compartment 20 in which, for example, luggage can be loaded is provided in the rear part of the passenger compartment 16 in the longitudinal direction of the vehicle body 14. The jack holding structure 10 is disposed, for example, on the side of the luggage compartment 20. Note that the jack holding structure 10 is not limited to being mounted on a vehicle 12 having a luggage compartment 20 in the rear part. The jack holding structure 10 may be mounted on a passenger vehicle having seats 18 for a passenger to sit on in the front and rear parts. In this case, the jack holding structure 10 is disposed further rearward than the rear seat disposed in the rear part of the vehicle 12.

The jack holding structure 10 is provided on one side wall 22 in the vehicle width direction of the vehicle body 14. Below, a case where the jack holding structure 10 is provided on the right side wall 22 (one side in the vehicle width direction) of the vehicle body 14 will be described. The side wall 22 of the vehicle body 14 is formed by an inner panel 221. The inner panel 221 is a panel that is arranged on the passenger compartment 16 side in the vehicle width direction of the vehicle body 14, and the inner panel 221 extends in the front-rear direction and vehicle height direction of the vehicle 12. Note that the jack holding structure 10 is not limited to being arranged on the right side wall 22 of the vehicle body 14. The jack holding structure 10 may also be arranged on the left side wall 22 of the vehicle body 14.

The vehicle body 14 includes an inner panel 221 and a passenger compartment panel 24 that is positioned inward of the inner panel 221 in the vehicle width direction (see FIG. 3).

The inner panel 221 has an opening 26 that opens in the vehicle width direction of the vehicle body 14. The opening 26 penetrates the vehicle body 14 in the vehicle width direction. The jack holding structure 10 is attached to the opening 26. An outer panel (not shown) is disposed on the outer side of the inner panel 221 in the vehicle width direction. The opening 26 opens, for example, in the front-rear direction and the vehicle height direction of the vehicle body 14. The upper part of the opening 26 has an upper fixing part 28U to which the upper part of the jack holding structure 10 is fixed. The lower part of the opening 26 has a lower fixing part 28L to which the lower part of the jack holding structure 10 is fixed.

The passenger compartment panel 24 constitutes the inner wall of the passenger compartment 16. In the vehicle width direction of the vehicle body 14, a storage section 30 is provided between the inner panel 221 and the passenger compartment panel 24 (see FIG. 4). The storage section 30 faces the opening 26 of the inner panel 221. The storage section 30 stores the jack holding structure 10 and the pantograph jack P. As shown in FIG. 1, the storage section 30 opens into the passenger compartment panel 24. The opening shape of the storage section 30 is, for example, a substantially rectangular shape that is elongated in the front-rear direction of the vehicle body 14. When the pantograph jack P is not attached or detached from the jack holding structure 10, a cover member (not shown) is attached to cover the storage section 30. When the cover member is removed from the storage section 30, the storage section 30 opens and is opened, making it possible to access the pantograph jack P.

As shown in FIG. 2, the jack holding structure 10 includes a holding bracket 32 and a holding member 34.

The retaining bracket 32 is formed from a plate material. The retaining bracket 32 is placed in the opening 26 of the vehicle body 14. The retaining bracket 32 is fixed to the upper fixing portion 28U and the lower fixing portion 28L of the inner panel 221. The retaining bracket 32 is placed so that the plate thickness direction of the retaining bracket 32 (the direction of the arrow B in FIG. 3) is the vehicle width direction of the vehicle body 14.

The retaining bracket 32 includes an upper bracket 36U and a lower bracket 36L that are arranged in the vehicle height direction of the vehicle body 14, and an overlapping portion 38 where a part of the upper bracket 36U and a part of the lower bracket 36L are connected and overlapped in the plate thickness direction in the vehicle height direction of the vehicle body 14.

The upper bracket 36U is formed, for example, by press-molding a plate material of a certain thickness. The upper bracket 36U is arranged along the vehicle height direction of the vehicle body 14. The upper bracket 36U is formed long in the up-down direction (vehicle height direction). The upper bracket 36U is arranged so that its width direction, which is perpendicular to the extension direction and plate thickness direction, is along the front-rear direction of the vehicle body 14.

The upper bracket 36U has an upper mounting portion 40, a first connection portion 42, and a first bead 44.

The upper mounting portion 40 is formed on the upper portion of the upper bracket 36U. The upper mounting portion 40 is fixed to the upper fixing portion 28U of the inner panel 221 by welding or the like. As shown in FIG. 3, the upper mounting portion 40 is fixed outward in the vehicle width direction relative to the upper fixing portion 28U. Note that the upper mounting portion 40 is not limited to being fixed outward in the vehicle width direction relative to the upper fixing portion 28U. For example, the upper mounting portion 40 may be fixed inward in the vehicle width direction relative to the upper fixing portion 28U.

As shown in FIG. 2, the first connection portion 42 is provided at the lower part of the upper bracket 36U. As shown in FIG. 3, when viewed from a direction perpendicular to the plate thickness direction of the upper bracket 36U, the first connection portion 42 is disposed outward in the vehicle width direction from the lower bracket 36L. Note that the first connection portion 42 is not limited to being disposed outward in the vehicle width direction from the lower bracket 36L. For example, the first connection portion 42 may be disposed inward in the vehicle width direction from the lower bracket 36L. As shown in FIG. 2, the first connection portion 42 includes a first base portion 421 and a first land portion 422 protruding outward in the vehicle width direction from the first base portion 421. The first base portion 421 is formed along the outer edge of the first connection portion 42. In a plan view of the upper bracket 36U, the first base portion 421 is formed in a U-shape that opens upward.

The first land portion 422 is surrounded by the first base portion 421 and is disposed in the center of the first connection portion 42. As shown in FIG. 3, when viewed from a direction perpendicular to the plate thickness direction of the upper bracket 36U, the first land portion 422 is offset in the plate thickness direction relative to the first base portion 421 and is parallel to it. In the plate thickness direction (arrow B direction), the first land portion 422 is disposed farther away from the lower bracket 36L than the first base portion 421.

The first bead 44 protrudes in the plate thickness direction (arrow B direction) relative to the first base portion 421. As shown in FIG. 2, when the upper bracket 36U is viewed from the plate thickness direction, the first bead 44 has a U-shaped first curved portion 441 that opens upward, and a set of first extension portions 442, 443 that extend from the end of the first curved portion 441 to the upper mounting portion 40. The set of first extension portions 442, 443 are spaced apart in the width direction of the upper bracket 36U. The first extension portions 442, 443 extend along the outer edge of the upper bracket 36U. The first curved portion 441 is provided on the first connecting portion 42. The lower ends of the first extension portions 442, 443 extend to the first connecting portion 42 and are connected to the first curved portion 441. In the first connection portion 42, the first curved portion 441 and a portion of the first extension portion 442, 443 form the boundary between the first base portion 421 and the first land portion 422.

The lower bracket 36L is formed, for example, by press-molding a plate material of a certain thickness. The lower bracket 36L is positioned offset below the upper bracket 36U in the vehicle height direction of the vehicle body 14. For example, the length of the lower bracket 36L in the vehicle height direction is shorter than the length of the upper bracket 36U. Note that the length of the lower bracket 36L in the vehicle height direction is not limited to being shorter than the length of the upper bracket 36U. The length of the lower bracket 36L in the vehicle height direction may be longer than the length of the upper bracket 36U. The lower bracket 36L is positioned so that its width direction perpendicular to the extension direction is aligned with the front-rear direction of the vehicle body 14.

The lower bracket 36L includes a lower mounting portion 46, a second connection portion 48, and a second bead 50.

The lower mounting portion 46 is formed on the lower part of the lower bracket 36L. The lower mounting portion 46 is fixed to the lower fixing portion 28L of the inner panel 221 by welding or the like. As shown in FIG. 3, the lower mounting portion 46 is fixed outward in the vehicle width direction relative to the lower fixing portion 28L. As a result, the upper and lower parts of the holding bracket 32 are fixed to the inner panel 221 with the holding bracket 32 facing the opening 26 of the vehicle body 14. Note that the lower mounting portion 46 is not limited to being fixed outward in the vehicle width direction relative to the lower fixing portion 28L. The lower mounting portion 46 may also be fixed inward in the vehicle width direction relative to the lower fixing portion 28L.

As shown in FIG. 2, the second connection portion 48 is provided at approximately the center of the lower bracket 36L. As shown in FIG. 3, when viewed from a direction perpendicular to the plate thickness direction of the lower bracket 36L, the second connection portion 48 is disposed inward in the vehicle width direction from the upper bracket 36U. Note that the second connection portion 48 is not limited to being disposed inward in the vehicle width direction from the upper bracket 36U. For example, the second connection portion 48 may be disposed outward in the vehicle width direction from the upper bracket 36U. As shown in FIG. 2, the second connection portion 48 includes a second base portion 481 and a second land portion 482 protruding inward in the vehicle width direction from the second base portion 481. The second base portion 481 is formed along the outer edge of the second connection portion 48. In a plan view of the lower bracket 36L, the second base portion 481 is formed in an inverted U-shape that opens downward.

The second land portion 482 is surrounded by the second base portion 481 and is disposed in the center of the second connection portion 48. The second land portion 482 and the second base portion 481 are offset in the plate thickness direction (arrow B direction) and are parallel to each other. As shown in FIG. 3, the second land portion 482 is disposed farther away from the upper bracket 36U than the second base portion 481 in the plate thickness direction (arrow B direction).

As shown in FIG. 2, the second land portion 482 has a set of fixing grooves 521, 522 that fix the retaining member 34, and a plurality of first to third protrusions 541, 542, 543 that abut against and are fixed to the upper bracket 36U. The fixing grooves 521, 522 are recessed in the plate thickness direction (the direction of arrow B in FIG. 3) from the second land portion 482 toward the upper bracket 36U. The fixing grooves 521, 522 extend in the vertical direction (vehicle height direction) and are arranged in parallel with a space in the width direction of the lower bracket 36L.

The first to third protrusions 541, 542, 543 each protrude from the second land portion 482 in the plate thickness direction toward the upper bracket 36U. The first protrusion 541 is disposed between a pair of fixing grooves 521, 522. The second protrusion 542 is disposed on the second base portion 481, spaced upward from the first protrusion 541. The third protrusion 543 is disposed on the opposite side to the first protrusion 541 across one fixing groove 521 in the width direction of the lower bracket 36L. The number of protrusions is not limited to three. There may be one protrusion, or there may be four or more protrusions.

The second bead 50 protrudes from the second base portion 481 of the lower bracket 36L in the plate thickness direction (arrow B direction in FIG. 3). When the lower bracket 36L is viewed from the plate thickness direction, the second bead 50 has an inverted U-shaped second curved portion 501 that opens downward, and a set of second extension portions 502, 503 that extend from the end of the second curved portion 501 to the lower mounting portion 46. The set of second extension portions 502, 503 are spaced apart in the width direction of the lower bracket 36L. The set of second extension portions 502, 503 extend along the outer edge of the lower bracket 36L. The second curved portion 501 is provided on the second connecting portion 48. The lower ends of the second extension portions 502, 503 extend to the second connecting portion 48 and are connected to the second curved portion 501. In the second connection portion 48, the second curved portion 501 and a portion of the second extension portions 502, 503 form the boundary between the second base portion 481 and the second land portion 482.

The overlapping portion 38 is a portion of the retaining bracket 32 where the lower portion of the upper bracket 36U and the upper portion of the lower bracket 36L overlap in the plate thickness direction (arrow B direction in FIG. 3) and are connected to each other in the vehicle height direction of the vehicle body 14. With the first connecting portion 42 and the second connecting portion 48 overlapped in the plate thickness direction and in contact with each other, the first connecting portion 42 and the second connecting portion 48 are connected in the plate thickness direction by welding such as MIG welding to form the overlapping portion 38. The first connecting portion 42 and the second connecting portion 48 are connected to each other by a plurality of welded portions W. The plurality of welded portions W are, for example, the first base portion 421 of the first connecting portion 42 and the second base portion 481 of the second connecting portion 48, and the first to third protrusions 541, 542, and 543 of the lower bracket 36L. As shown in FIG. 3, the thickness of the overlapping portion 38 in the plate thickness direction is the sum of the plate thickness T1 of the upper bracket 36U and the plate thickness T2 of the lower bracket 36L.

As shown in FIG. 2, in the vehicle height direction of the vehicle body 14, the length L1 of the overlapping portion 38 is, for example, in the range of 20% to 50% of the length L2 of the holding bracket 32. Furthermore, it is preferable that the length L1 of the overlapping portion 38 is, for example, approximately 30% to 40% of the length L2 of the holding bracket 32.

The overlapping portion 38 includes a pair of reinforcing beads 561, 562. The pair of reinforcing beads 561, 562 extend, for example, in the front-rear direction of the vehicle body 14 (the width direction of the retaining bracket 32) intersecting the plate thickness direction of the retaining bracket 32 (the direction of the arrow B in FIG. 3) and the vehicle height direction of the vehicle body 14. The pair of reinforcing beads 561, 562 are spaced apart and arranged in parallel in the vehicle height direction of the vehicle body 14. The reinforcing beads 561, 562 are formed in the first connection portion 42 of the upper bracket 36U. The reinforcing beads 561, 562 extend along the width direction of the upper bracket 36U. The reinforcing beads 561, 562 extend from the first base portion 421 on one side in the width direction through the first land portion 422 to the first base portion 421 on the other side in the width direction.

The reinforcing beads 561, 562 are not limited to being formed on the first connection portion 42 of the upper bracket 36U. Reinforcing beads may be formed on the second connection portion 48 of the lower bracket 36L, or reinforcing beads may be formed on both the upper bracket 36U and the lower bracket 36L. The reinforcing beads 561, 562 are not limited to a set. There may be one reinforcing bead, or there may be three or more reinforcing beads.

When viewed from the plate thickness direction of the holding bracket 32, the first curved portion 441 of the first bead 44 and the second curved portion 501 of the second bead 50 overlap in the plate thickness direction in the overlapping portion 38 to form a ring. The first curved portion 441 and the second curved portion 501 overlapping in the plate thickness direction form a ring-shaped overlapping bead portion 58.

The holding member 34 is fixed to the holding bracket 32 and holds the pantograph jack P (see FIG. 4). As shown in FIG. 3, the holding member 34 is disposed inward in the vehicle width direction relative to the holding bracket 32. In other words, the holding member 34 is disposed on one side of the holding bracket 32 in the plate thickness direction. The holding member 34 is disposed in the storage section 30 of the vehicle body 14.

As shown in FIG. 2, the retaining member 34 is formed, for example, by bending a metal wire. The retaining members 34 are provided in pairs in parallel in the width direction perpendicular to the plate thickness direction of the retaining bracket 32 and the vehicle height direction of the vehicle body 14. Note that the retaining members 34 are not limited to being provided in pairs spaced apart in the width direction. Three or more retaining members 34 may be provided in parallel and spaced apart in the width direction of the retaining bracket 32.

Each of the pair of holding members 34 includes a fixing portion 60, an upper arm portion 62U, and a lower arm portion 62L. The fixing portion 60 is disposed along the vehicle height direction of the vehicle body 14 and is fixed to the holding bracket 32. Each fixing portion 60 is inserted into the fixing grooves 521, 522 of the lower bracket 36L. For example, with a portion of the fixing portion 60 inserted into the fixing grooves 521, 522, the fixing portion 60 is fixed to the fixing grooves 521, 522 by welding such as MIG welding.

As shown in FIG. 3, the lower end of the fixing part 60 has a holding arm part 64 that extends downward. The holding arm part 64 bends inward in the vehicle width direction from the lower end of the fixing part 60 and extends downward. The holding arm part 64 moves away from the holding bracket 32 inward in the vehicle width direction. The holding arm part 64 extends diagonally downward as it moves away from the fixing part 60.

The upper arm portion 62U is provided at the upper end of the fixing portion 60. When the holding member 34 is fixed to the holding bracket 32, the upper arm portion 62U protrudes in a direction away from the holding bracket 32. The protruding direction of the upper arm portion 62U is inward in the vehicle width direction of the vehicle body 14. In the vehicle width direction of the vehicle body 14, the upper arm portion 62U is inclined upward as it moves away from the fixing portion 60 in the vehicle width direction. When viewed from the width direction of the holding bracket 32, the upper arm portion 62U and the holding arm portion 64 are approximately perpendicular to each other.

The upper arm portion 62U has a tip portion 621 that is furthest from the holding bracket 32. The tip portion 621 of the upper arm portion 62U is positioned furthest inward in the vehicle width direction. The tip portion 621 of the upper arm portion 62U has a hook portion 66 that is bent downward. The hook portion 66 protrudes downward from the upper arm portion 62U. When the pantograph jack P is held in the jack holding structure 10, a portion of the pantograph jack P is held by the hook portion 66.

The lower arm portion 62L is provided at the lower end of the fixed portion 60 via the holding arm portion 64. The lower arm portion 62L is connected to the lower end of the holding arm portion 64. The lower arm portion 62L is bent so as to be approximately perpendicular to the holding arm portion 64. When the holding member 34 is fixed to the holding bracket 32, the lower arm portion 62L protrudes in a direction away from the holding bracket 32. The protruding direction of the lower arm portion 62L is the inside of the vehicle width direction of the vehicle body 14. In the vehicle width direction of the vehicle body 14, the lower arm portion 62L is inclined upward as it moves away from the fixed portion 60 in the vehicle width direction. When viewed from the width direction of the holding bracket 32, the lower arm portion 62L and the upper arm portion 62U are approximately parallel. The lower arm portion 62L and the holding arm portion 64 are approximately perpendicular to each other.

The length of the upper arm 62U protruding from the fixed part 60 is approximately the same as the length of the lower arm 62L protruding from the fixed part 60. The upper arm 62U and the lower arm 62L are formed with a length that can hold the pantograph jack P.

As shown in FIG. 2, when the pair of retaining members 34 are fixed to the lower bracket 36L, the pair of retaining members 34 are arranged so as to overlap the overlapping portion 38 when viewed from the plate thickness direction. Note that this is not limited to the case where the pair of retaining members 34 are arranged so as to overlap the entirety of the overlapping portion 38 when viewed from the plate thickness direction shown in FIG. 2. The retaining members 34 may be arranged so as to overlap at least a portion of the overlapping portion 38.

Next, we will explain the pantograph jack P held by the jack holding structure 10.

As shown in FIG. 4, the pantograph jack P includes a base 70, a pair of lower arms 721, 722 rotatably supported on the base 70, a pair of upper arms 741, 742 rotatably supported on the ends of the lower arms 721, 722 via connecting pins 80, and a receiving portion 76 disposed above the base 70 and connected to the pair of upper arms 741, 742.

The base 70 and the receiving part 76 are positioned in the center of the width of the pantograph jack P. The base 70 and the receiving part 76 face each other in the vertical direction perpendicular to the width direction. When the pantograph jack P is in use, the lower surface 701 of the base 70 is placed on the road surface G (see Figure 1) or the like.

The pair of lower arms 721, 722 are rotatably supported on the base 70 via a support pin 78. The pair of lower arms 721, 722 extend outward in the width direction away from the base 70. The pair of upper arms 741, 742 are rotatably supported on the receiving portion 76 via a support pin 78. The pair of upper arms 741, 742 extend outward in the width direction away from the base 70.

The widthwise outer ends of the lower arms 721 and 722 and the widthwise outer ends of the upper arms 741 and 742 are rotatably supported via a connecting pin 80.

A rod 82 is provided between a pair of lower arms 721, 722 and a pair of upper arms 741, 742, and by rotating the rod 82 extending in the width direction, the outer ends of the lower arms 721, 722 and the upper arms 741, 742 in the width direction move toward or away from each other. When they move toward each other, the lower arms 721, 722 and the upper arms 741, 742 rotate to extend in the vertical direction, and the receiving portion 76 rises relative to the base 70. When they move away from each other, the lower arms 721, 722 and the upper arms 741, 742 rotate to approach each other in the vertical direction, and the receiving portion 76 descends toward the base 70.

When holding a pantograph jack P in the jack holding structure 10, the receiving portion 76 is placed between the pair of holding members 34 in the storage portion 30, and the upper arms 741, 742 are moved outward in the vehicle width direction from the hook portion 66 of the upper arm portion 62U. That is, as shown in FIG. 3, the upper arms 741, 742 of the pantograph jack P are inserted between the hook portion 66 and the fixed portion 60. The pair of upper arms 741, 742 are positioned below the upper arm portion 62U.

Next, the lower surface 701 of the base 70 is placed on the lower arm portion 62L. The base 70 of the pantograph jack P is moved toward the holding bracket 32 along the lower arm portion 62L. The pantograph jack P moves toward the holding bracket 32, and the side of the base 70 abuts against the holding arm portion 64. As a result, the pantograph jack P is positioned and held by the holding member 34 in the vehicle width direction of the car body 14. The pantograph jack P is held in a state in which the lower surface 701 of the base 70 is inclined downward toward the outside in the vehicle width direction. The inclination angle θ of the pantograph jack P is the angle between the vertical line L extending in the vehicle height direction and the holding arm portion 64. At this time, the load of the pantograph jack P is applied to the overlap portion 38 of the holding bracket 32 via the holding arm portion 54 of the holding member 34. Compared to when the underside 701 of the pantograph jack P is placed on a horizontal flat surface, by placing it on the lower arm portion 62L, the center of gravity of the pantograph jack P is positioned closer to the overlapping portion 38.

The underside 701 (lower part) of the base 70 of the pantograph jack P is held by the lower arm part 62L. The side of the base 70 is held in the vehicle width direction by the holding arm part 64. The upper arms 741, 742 (upper part) of the pantograph jack P are held by the upper arm part 62U.

This embodiment provides the following advantages:

As shown in FIG. 2, the jack holding structure 10 includes a holding bracket 32 formed from a plate material and fixed to the vehicle body 14, and a holding member 34 fixed to the holding bracket 32 and holding the pantograph jack P. The holding bracket 32 has an upper bracket 36U and a lower bracket 36L. In the vehicle height direction of the vehicle body 14, the upper part of the lower bracket 36L and the lower part of the upper bracket 36U overlap in the plate thickness direction, forming an overlapping portion 38 that is connected to each other in the plate thickness direction.

By increasing the thickness of the holding bracket 32 in the plate thickness direction by the overlapping portion 38, it is possible to increase the strength in the vertical direction (vehicle height direction) while suppressing an increase in the weight of the holding bracket 32. This allows the overlapping portion 38 to effectively bear the load when the pantograph jack P is held by the holding bracket 32. Compared to a configuration in which the plate thickness of the entire holding bracket is made thick, the holding bracket 32 can be made thinner and smaller.

The retaining member 34 is positioned so that it overlaps at least a portion of the overlapping portion 38 when viewed from the plate thickness direction, so that the load of the pantograph jack P can be effectively received by the retaining member 34 positioned at the overlapping portion 38, which has high strength.

As shown in FIG. 3, the holding member 34 includes a fixed portion 60 arranged along the vehicle height direction and fixed to the holding bracket 32, an upper arm portion 62U provided at the upper end of the fixed portion 60 and protruding in a direction away from the holding bracket 32, and a lower arm portion 62L provided at the lower end of the fixed portion 60 and protruding in a direction away from the holding bracket 32. As a result, by holding the pantograph jack P with the upper arm portion 62U and the lower arm portion 62L, it is possible to reduce the number of parts compared to when the upper arm portion 62U and the lower arm portion 62L are constructed as separate members.

As shown in FIG. 3, the overlapping portion 38 has reinforcing beads 561, 562 that extend in the front-rear direction (width direction) of the vehicle 12 intersecting the plate thickness direction and the vehicle height direction, so that the strength of the overlapping portion 38 can be more effectively increased by the reinforcing beads 561, 562. This can increase the strength of the holding bracket 32 in the torsional direction.

The lower arm portion 62L supports the underside 701 (base 70) of the pantograph jack P, and as the lower arm portion 62L moves away from the fixed portion 60 in the vehicle width direction of the vehicle body 14, it extends upward. As a result, when the pantograph jack P is supported by the holding member 34, the load of the pantograph jack P is applied toward the holding bracket 32, so that the load can be effectively received by the strong overlapping portion 38. By placing the base 70 of the pantograph jack P on the lower arm portion 62L, the pantograph jack P is held by the lower arm portion 62L in a state shifted outward in the vehicle width direction, thereby improving the mountability of the pantograph jack P.

The upper arm portion 62U has a tip portion 621 that is furthest from the holding bracket 32, and the tip portion 621 is provided with a hook portion 66 that bends downward to hold the pantograph jack P. As a result, when the pantograph jack P is supported by the holding member 34, the upper portion of the pantograph jack P can be inserted between the hook portion 66 and the fixing portion 60, so that the upper portion of the pantograph jack P can be easily held by the hook portion 66. The hook portion 66 can prevent the pantograph jack P from moving in the direction of the passenger compartment 16.

As shown in FIG. 2, multiple holding members 34 are provided in parallel in the width direction (fore-and-aft direction of the car body 14) perpendicular to the plate thickness direction and the vehicle height direction. This allows the pantograph jack P to be held along the fore-and-aft direction of the car body 14 by multiple holding members 34, making it possible to simplify and reduce the weight of the jack holding structure 10 compared to a configuration in which the pantograph jack is held in the fore-and-aft direction by a single holding member with a width in the fore-and-aft direction.

The upper bracket 36U has a first bead 44 having a U-shaped first curved portion 441 that opens upward when viewed from the plate thickness direction, and the lower bracket 36L has a second bead 50 having an inverted U-shaped second curved portion 501 that opens downward when viewed from the plate thickness direction. In the overlapping portion 38, the first curved portion 441 and the second curved portion 501 overlap in the plate thickness direction to form an annular overlapping bead portion 58. As a result, by overlapping the first bead 44 and the second bead 50 in the overlapping portion 38 to form an annular overlapping bead portion 58, the strength of the overlapping portion 38 can be further increased with a simple configuration.

In the vehicle height direction of the vehicle body 14, the length L1 of the overlapping portion 38 is set in the range of 20 to 50% of the length L2 of the holding bracket 32, so that the load burden when holding the pantograph jack P and the increased weight of the holding bracket 32 can be effectively balanced.

The following additional information is provided in addition to the disclosure above:

(Appendix 1)
A jack holding structure (10) is mounted on a vehicle (12) and holds a pantograph jack (P), comprising: a holding bracket (32) formed from a plate material and fixed to a body (14) of the vehicle; and a holding member (34) fixed to the holding bracket and holding the pantograph jack on one side of the holding bracket in a plate thickness direction, the holding bracket having an upper bracket (36U) and a lower bracket (36L) arranged in a vehicle height direction, and an overlap portion (38) in which an upper portion of the lower bracket and a lower portion of the upper bracket overlap in the plate thickness direction in the vehicle height direction and are connected to each other in the plate thickness direction.

With this configuration, the thickness of the holding bracket is increased in the plate thickness direction by the overlapping portion, which increases the strength of the holding bracket while suppressing an increase in its weight. This allows the overlapping portion to effectively bear the load when the pantograph jack is held by the holding bracket.

(Appendix 2)
In the jack holding structure described in Appendix 1, the holding member may be arranged so as to overlap at least a portion of the overlap portion when viewed from the plate thickness direction.

With this configuration, the retaining member is positioned in the plate thickness direction at a position that overlaps the overlapping portion with high strength, allowing the retaining member to effectively support the load of the pantograph jack.

(Appendix 3)
In the jack holding structure described in Appendix 1 or 2, the holding member may include a fixed portion (60) arranged along the vehicle height direction and fixed to the holding bracket, an upper arm portion (62U) provided at an upper end of the fixed portion and protruding in a direction away from the holding bracket, and a lower arm portion (62L) provided at a lower end of the fixed portion and protruding in a direction away from the holding bracket.

With this configuration, the pantograph jack is held by the upper arm portion and the lower arm portion, which reduces the number of parts compared to when the upper arm portion and the lower arm portion are made of separate parts.

(Appendix 4)
In the jack holding structure described in Appendix 1, the overlapping portion may be provided with reinforcing beads (561, 562) extending in a direction intersecting the plate thickness direction and the vehicle height direction.

With this configuration, the reinforcing bead can more effectively increase the strength of the overlapping portion. The torsional strength of the retaining bracket can be increased.

(Appendix 5)
In the jack holding structure described in Appendix 3, the lower arm portion supports a lower part of the pantograph jack, and the lower arm portion may extend upward as it moves away from the fixed portion in the vehicle width direction of the vehicle body.

With this configuration, when the pantograph jack is supported by the holding member, the load of the pantograph jack is applied toward the holding bracket, so the load can be effectively received by the strong overlapping portion. By placing the lower part of the pantograph jack on the lower arm portion, the pantograph jack is held by the lower arm portion in a state close to the holding bracket, improving the mountability of the pantograph jack.

(Appendix 6)
In the jack holding structure described in Appendix 3 or 5, the upper arm portion has a tip portion (621) that is furthest from the holding bracket, and the tip portion may be provided with a hook portion (66) that is bent downward to hold the pantograph jack.

With this configuration, when the pantograph jack is supported by the holding member, the upper part of the pantograph jack can be easily held by the hook part by inserting the upper part of the pantograph jack between the hook part and the fixed part. The hook part prevents the pantograph jack from moving toward the inside of the vehicle cabin.

(Appendix 7)
In the jack holding structure described in any one of Supplementary Notes 1 to 6, the holding members may be provided in parallel in a direction perpendicular to the plate thickness direction and the vehicle height direction.

With this configuration, the pantograph jack can be held in the fore-and-aft direction of the vehicle body by multiple holding members, and the jack holding structure can be simplified and made lighter than a configuration in which the pantograph jack is held in the fore-and-aft direction by a single holding member with a width in the fore-and-aft direction.

(Appendix 8)
In the jack holding structure described in any one of Appendices 1 to 7, the upper bracket includes a first bead (44) having a U-shaped first curved portion (441) that opens upward when viewed from the plate thickness direction, and the lower bracket includes a second bead (50) having an inverted U-shaped second curved portion (501) that opens downward when viewed from the plate thickness direction, and in the overlapping portion, the first curved portion and the second curved portion may overlap in the plate thickness direction to form an annular overlapping bead portion (58).

With this configuration, the first bead and the second bead are overlapped in the overlapping portion to form an annular overlapping bead portion, which allows the strength of the overlapping portion to be further increased with a simple configuration.

(Appendix 9)
In the jack holding structure described in any one of Appendices 1 to 8, the length (L1) of the overlapping portion in the vehicle height direction may be in the range of 20 to 50% of the length (L2) of the holding bracket.

With this configuration, by providing an overlapping portion that is 20-50% of the length of the holding bracket, it is possible to effectively balance the load burden when holding the pantograph jack and the increased weight of the holding bracket.

The present invention is not limited to the above disclosure, and various configurations may be adopted without departing from the gist of the present invention.
