Description

  The present invention relates to a slope unit structure.

  For example, Patent Document 1 discloses a vehicle rear structure that includes a slope unit that is pivotally supported with a hinge disposed at the rear of the vehicle as a rotation shaft and that can be deployed outside the vehicle and housed in the vehicle interior. Has been.

  In Patent Document 1, a slope unit deployed outside a vehicle is grounded on a ground surface, and an object to be mounted such as a wheelchair on which a cared person rides is moved into the vehicle interior along the slope unit.

Japanese Patent No. 5507514

  By the way, in the vehicle rear part structure disclosed in Patent Document 1, the rotation operation of the slope unit is allowed through a hinge disposed in the vehicle rear part. For this reason, when a wheelchair or the like is positioned on the slope unit when the slope unit is deployed, the slope unit bends due to the weight of the wheelchair or the cared person, and the slope unit when the wheelchair or cared person moves on the slope unit. There is a possibility that the inclination angle (uphill gradient) becomes large.

  In order to suppress the inclination angle (uphill gradient) of the slope unit, it is conceivable to reduce the amount of deflection of the slope unit by increasing the section modulus of the side rails arranged on both sides of the slope unit. However, when the sectional modulus of the side rail is increased, the width dimension of the side rail along the vehicle width direction is increased as compared with the conventional case. Thereby, the road width (width in the vehicle width direction) of the slope unit disposed between the side rails on both sides is narrowed, which may hinder the wheelchair when moving on the slope unit.

  This invention is made in view of the said point, and provides the slope unit structure which can suppress the amount of bending of a slope unit when a to-be-mounted thing is mounted on a slope unit. Objective.

In order to achieve the above object, the present invention has a slope unit composed of a slope composed of at least one or more flat panel portions, and the slope unit is used with a hinge fixed to a vehicle body as a rotation axis. In a slope unit structure that can be unfolded and stowed by being pivotally supported , when the slope unit is deployed outside the vehicle and is grounded to the grounding surface, the slope on the vehicle body side forms a vehicle body. A rotation suppression mechanism that suppresses rotation in the direction opposite to the storage direction with the hinge fixed to the floor as a rotation axis is provided.

  According to the present invention, the rotation suppression mechanism functions as a stopper that suppresses rotation in the direction opposite to the storage direction with respect to the slope unit about the hinge as a rotation axis, so that the object to be mounted on the slope unit. The amount of bending of the slope unit when mounted can be suppressed. Moreover, in this invention, it can prevent that the climbing slope of a slope unit becomes large when a to-be-mounted thing moves to the vehicle body side. Furthermore, in the present invention, by ensuring the desired flexural rigidity of the slope unit, it is possible to avoid the road width (width in the vehicle width direction) of the slope unit from being narrowed when the mounted object moves.

  Further, the present invention is characterized in that the rotation suppression mechanism includes a slope-side protrusion provided on the slope on the vehicle body side, and a hinge-side protrusion provided on the hinge and in contact with the slope-side protrusion. To do.

  According to the present invention, the rotation suppressing mechanism has a simple structure including the slope-side protrusion and the hinge-side protrusion, so that the slope unit structure can be reduced in size and weight, and is provided from the slope unit. Can be suitably supported by the vehicle body to which the hinge is fixed.

  Furthermore, the present invention is characterized in that at least one of the slope side protrusion and the hinge side protrusion includes a contact position adjusting mechanism for adjusting a contact position of the slope side protrusion and the hinge side protrusion. To do.

  According to the present invention, by providing the contact position adjusting mechanism, for example, it is possible to absorb an assembly error and a manufacturing error of a slope and a hinge, and it is possible to suppress a contact failure when it deteriorates.

  Furthermore, the present invention is characterized in that a cushioning material is attached to at least one of the contact surfaces of the slope side protrusion and the hinge side protrusion.

  According to the present invention, by providing the cushioning material on the abutting surface, it is possible to suppress a hitting sound when the slope side projection and the hinge side projection abut. Further, even when the angle of the contact surface between the slope-side protrusion and the hinge-side protrusion changes when the slope unit is bent, the contact surfaces can be uniformly contacted by the cushioning material.

  Still further, according to the present invention, the rotation suppressing mechanism has a protruding portion that protrudes in the vehicle width direction from a side surface of the slope on the vehicle body side, and a groove portion that is provided on the hinge and faces the protruding portion. It is characterized by.

  According to the present invention, the protruding portion is held in a state where it faces the groove portion, and the protruding portion is not exposed to the outside. For this reason, in this invention, it can avoid suitably that a to-be-mounted object and a caregiver contact a protrusion part when moving on a slope unit.

  According to the present invention, it is possible to obtain a slope unit structure that can suppress the amount of bending of the slope unit when a mounted object is mounted on the slope unit.

  Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate. In each figure, “front and rear” indicates the vehicle longitudinal direction, “left and right” indicates the left and right direction (vehicle width direction) as viewed from the driver's seat, and “up and down” indicates the vertical vertical direction.

First, operation | movement of the slope unit structure 10 which concerns on embodiment of this invention is demonstrated roughly based on FIG.
The slope unit structure 10 is rotated from the housed state (see FIG. 2) placed in the passenger compartment 16 to the vehicle exterior (clockwise direction) with the pair of hinges 22 as pivot axes. By doing so, it becomes an upright state (see FIG. 2) that stands up substantially along the vertical direction. Subsequently, the slopes 12a to 12c constituting the slope unit 12 are slid toward the outside of the passenger compartment while further rotating the slope unit 12 in the outward direction (clockwise direction) with the hinge 22 as a turning shaft. Thus, the vehicle rear end portion of the slope unit 12 is brought into a developed state (grounded state) in which the grounding surface is grounded (see FIGS. 1 and 2).

  As described above, the slope unit structure 10 easily shifts to the housed state where the slope unit 12 is housed in the passenger compartment 16, the standing state, and the unfolded state (grounded state) where the slope unit 12 is deployed and grounded outside the passenger compartment. can do.

  Further, contrary to the above, after the slopes 12a to 12c are slid and stacked in the front of the vehicle from the unfolded state (grounding state), the slope unit 12 is rotated to the vehicle compartment 16 side with the hinge 22 as the pivot shaft. By moving it, it will be in the standing state (see FIG. 2) which has stood up substantially along the vertical direction. Further, from the standing state, the slope unit 12 is turned to the vehicle compartment 16 side (counterclockwise direction) about the hinge 22 as a turning shaft, thereby returning to the housed state (see FIG. 2) placed in the vehicle compartment 16. Can be migrated.

  As shown in FIG. 1, the vehicle 14 includes a vehicle body floor 18 that constitutes a passenger compartment 16. The vehicle body floor 18 is provided with an inclined surface 20 (see FIG. 2) that is inclined so as to be gradually positioned downward as it goes rearward of the vehicle. On the inclined surface 20, the slope unit 12 accommodated in the vehicle compartment 16 is placed. A pair of hinges 22 fixed to the vehicle body floor 18 are disposed at the vehicle rear position of the inclined surface 20. The pair of hinges 22 are disposed at positions close to the rear vertical wall of the vehicle body at a predetermined interval on both sides along the vehicle width direction.

  The slope unit structure 10 is used, for example, in the vehicle 14 provided with a back door 26 (tailgate) that opens and closes the vehicle body rear opening 24. The slope unit structure 10 is not limited to the vehicle 14 having the back door 26, and can be applied to, for example, a vehicle having left and right rear doors (not shown).

  The slope unit structure 10 includes a slope unit 12. The slope unit 12 includes a plurality of slopes 12a to 12c that are slidable along the longitudinal direction. In the unfolded state (grounding state) shown in FIG. 1, each of the slopes 12a to 12c includes a slope 12a that is disposed closest to the vehicle body side, a slope 12c that is positioned on the grounding surface side, and a slope 12a on the vehicle body side. And a slope 12b at the center disposed between the slope 12c and the slope 12c on the ground plane side.

  The slope 12a arranged at the position closest to the vehicle body functions as a “vehicle body side slope” and is hereinafter referred to as a vehicle body side slope 12a. A ring-shaped handle 15 is connected to the upper surface of the slope 12c on the ground surface side (see FIG. 1).

  Each of the slopes 12a to 12c is a rectangular and flat panel portion 28 on which an object to be mounted (for example, a wheelchair (not shown)) is mounted, and side walls that are coupled to face both sides of the panel portion 28 along the vehicle width direction. A pair of side rail portions 30, 30 made of In each of the slopes 12a to 12c, the side rails 30 are formed to have the same cross-sectional shape in the direction perpendicular to the axis. In this embodiment, the case where the slope unit 12 is configured by three slopes 12a to 12c is illustrated, but the present invention is not limited to this, and may be configured by at least one slope. That's fine.

  Further, the slope unit structure 10 is attached to the rear portion of the vehicle body of the vehicle body floor 18, and a pair of hinges 22 that pivotally support one end portion of the slope unit 12 and the deployment of the slope unit 12 to the outside of the vehicle body. A rotation suppression mechanism 32 that suppresses the side slope 12a from rotating in the direction opposite to the storage direction. The slope unit 12 is disposed to be rotatable inside and outside the vehicle interior with a pair of hinges 22 fixed to the vehicle body floor 18 as pivot axes.

  The pair of hinges 22 have the same configuration, and are arranged in line-symmetric shapes on one side (right side) and the other side (left side) of the vehicle body floor 18 in the vehicle width direction. For this reason, the hinge 22 arranged on one side (right side) will be described in detail, and the description of the hinge 22 arranged on the other side (left side) will be omitted.

  FIG. 3A is a perspective view showing the hinge and the rotation suppression mechanism, and FIG. 3B is a side view for explaining the operation of the hinge and the rotation suppression mechanism.

  The hinge 22 includes a fixing member 36 integrally having a vertical wall portion 34a and a horizontal wall 34b formed by bending a flat plate body into a substantially L-shaped cross section. A shaft portion 38 made of a hollow cylindrical body and projecting inward in the vehicle width direction is connected to the vertical wall portion 34a. The shaft portion 38 is configured to extend substantially in parallel with the lateral wall portion 34b. The shaft portion 38 is pivotally mounted in the through hole 40 so as to be rotatable. The through hole 40 is formed in the vehicle front end portion 30a of the side rail portion 30 of the slope 12a on the vehicle body side.

  In this embodiment, the shaft portion 38 is formed of a hollow pipe material in order to achieve weight reduction, but may be formed of a solid rod member (not shown) in order to increase rigidity. A pair of bolt fastening holes 44 to which the pair of bolts 42 are fastened are formed in the horizontal wall 34b. By fastening the bolt 42 to the bolt fastening hole 44, the hinge 22 (fixing member 36) is fixed to the vehicle body rear portion of the vehicle body floor 18.

  The rotation suppression mechanism 32 includes a slope-side protrusion 46 provided on the slope 12 a on the vehicle body side, and a hinge-side protrusion 48 provided on the hinge 22 and capable of contacting the slope-side protrusion 46.

  The slope-side protrusion 46 is provided on the side surface (the lower surface when deployed) of the vehicle front end portion 30a of the side rail portion 30 of the slope 12a on the vehicle body side. The slope-side protrusion 46 extends along the vehicle width direction, and is formed by a ridge that has a substantially rectangular axial cross section. The slope-side protrusion 46 contacts the hinge-side protrusion 48 from the rear of the vehicle when the slope unit 12 is deployed.

  In the present embodiment, the case where the slope-side protrusion 46 is formed integrally with the side rail portion 30 is illustrated, but the present invention is not limited to this. For example, the slope-side protrusion 46 may be configured separately from the side rail portion 30 and may be integrally coupled via a fastening means or a joining means (not shown). Further, the slope-side protrusion 46 that functions as a stopper is not attached to the side rail portion 30, but is attached to the vehicle body below the slope 12a separated from the side rail portion 30 (for example, the upper surface of the rear bumper or the upper surface of the floor). You may do it. By doing in this way, it can suppress that the slope 12a rotates in the opposite direction to a storage direction. Further, the stopper when separated from the hinge 22 may be configured to suppress the rotation of the slope 12a with one member, or may be configured with two members. Furthermore, this stopper may be provided so that the position can be adjusted.

  The hinge-side protrusion 48 has a substantially rectangular axial cross section, and is formed by a protrusion that protrudes from the upper surface of the lateral wall 34 b of the fixing member 36. The protruding portion is formed continuously from one end along the vehicle width direction of the horizontal wall 34b to the other end having the vertical wall 34a. The other end of the hinge-side protrusion 48 is integrally coupled to the wall surface of the vertical wall 34a, thereby improving rigidity and strength.

  In the present embodiment, the case where the hinge-side protrusion 48 is formed integrally with the lateral wall 34b of the fixing member 36 is illustrated, but the present invention is not limited to this. For example, the hinge-side protrusion 48 may be formed separately from the fixing member 36 (lateral wall 34b), and both may be integrally coupled via a fastening means or a joining means (not shown).

  In the present embodiment, the shape of the hinge-side protrusion 48 as viewed from the front side of the vehicle is formed in a strip shape (horizontally long rectangle) having a uniform width, but is not limited thereto. The shape of the hinge-side protrusion 48 as viewed from the front side of the vehicle is, for example, that one side portion continuous to the vertical wall portion 34a is a belt-like portion (horizontally long rectangle) having a uniform width, and the other side portion is directed to the horizontal wall portion 34b. As a triangular part having an inclined surface that falls, a trapezoidal shape combining a band-like part and a triangular part may be used.

  The slope unit structure 10 according to the present embodiment is basically configured as described above. Next, the function and effect will be described.

  When the slope unit 12 shifts to the deployed state via the stowed state and the standing state, the slope-side protrusion 46 of the slope 12a on the vehicle body side integrally rotates about the hinge 22 as a rotation axis, and the hinge of the fixing member 36 It abuts on the side protrusion 48. The movable slope-side protrusion 46 abuts against the fixed-side hinge-side protrusion 48, thereby suppressing the slope unit 12 from rotating in the direction opposite to the storage direction. In this case, it is preferable that the slope-side protrusion 46 and the hinge-side protrusion 48 abut when the slope unit 12 is grounded.

  Note that the slope-side projection 46 of the slope 12a on the vehicle body side and the hinge-side projection 48 of the fixing member 36 are in a non-contact state when the slope unit 12 is deployed, and an object to be mounted is mounted on the slope unit 12. Thus, the load may be made only when the weight of the object to be loaded is applied to the slope unit 12.

  As described above, in the present embodiment, the rotation suppression mechanism 32 functions as a stopper that suppresses the hinge 22 from rotating in the direction opposite to the storage direction with respect to the slope unit 12 with the rotation axis as a rotation axis. The amount of deflection of the slope unit 12 when an object to be mounted (for example, a wheelchair or the like) is mounted on 12 can be suppressed. Further, in the present embodiment, it is possible to prevent the ascending slope of the slope unit 12 from increasing when the mounted object moves to the vehicle body side. Furthermore, in the present embodiment, by ensuring the desired flexural rigidity of the slope unit 12, the road width of the slope unit 12 (the width in the vehicle width direction of the panel portion 28) when the mounted object moves on the slope unit 12. Can be avoided.

  Furthermore, in the present embodiment, the rotation suppression mechanism 32 has a simple structure including the slope-side protrusion 46 and the hinge-side protrusion 48, so that the slope unit structure 10 can be reduced in size and weight. The load applied from the slope unit 12 can be suitably supported by the vehicle body floor 18 to which the hinge 22 is fixed.

  Furthermore, in the present embodiment, by securing the desired bending rigidity of the slope unit 12, the cross-sectional area in the direction perpendicular to the axis of the side rail portion 30 constituting each of the slopes 12a to 12c is reduced as compared with the conventional case. Can do. In addition, the number of molds for manufacturing the side rail portion 30 is made by sharing the cross-sectional shape of the side rail portion 30 constituting the slopes 12a to 12c on the vehicle body side, the center, and the ground plane side in common. And the mold cost can be reduced.

  Furthermore, in this embodiment, the surface pressure on the contact surface can be reduced by relatively increasing the area of the contact surface of the slope-side protrusion 46 and the hinge-side protrusion 48 constituting the rotation suppression mechanism 32. it can.

  Furthermore, in the present embodiment, the end in the vehicle width direction of the hinge-side protrusion 48 protruding from the upper surface of the horizontal wall 34b of the fixing member 36 extends to the vertical wall 34a and is integrally coupled to the vertical wall 34a. Thus, the rigidity and strength of the hinge side protrusion 48 can be improved.

  Furthermore, in this embodiment, the contact surface between the slope-side protrusion 46 and the hinge-side protrusion 48 is a flat surface (see FIG. 3B) orthogonal to the upper surface of the lateral wall portion 34b, but is not limited to this. It is not something. For example, it may be formed by an inclined surface, an uneven surface, a curved surface, a composite surface including a curved surface, or the like that intersects the upper surface of the horizontal wall portion 34b. Reinforcing portions that reinforce the rigidity and strength of the slope-side projection 46 and the hinge-side projection 48 are respectively provided at the corner portion of the slope-side projection 46 on the vehicle rear side and the corner portion of the hinge-side projection 48 on the vehicle front side. You may do it. Furthermore, both the shape of the contact surface and the reinforcing portion may be provided side by side.

  Furthermore, in the present embodiment, the contact position (position of the contact surface) between the slope-side protrusion 46 and the hinge-side protrusion 48 is set below the vehicle front end 30a of the slope 12a on the vehicle body side. Although it arrange | positions on the virtual line (vertical line) S which passes along the center O, it is not limited to this.

  For example, the contact position is disposed at a position behind the imaginary line (vertical line) S passing through the center O of the shaft portion 38 and below the vehicle front end 30a of the slope 12a on the vehicle body side. It may be. Further, for example, the contact position is disposed at a position in front of the vehicle with respect to a virtual line (vertical line) S passing through the center O of the shaft portion 38 and at a position below the vehicle front end 30a of the slope 12a on the vehicle body side. You may make it do. Further, for example, the contact position is arranged on an imaginary line (vertical line) S passing through the center O of the shaft portion 38 and at a position above the vehicle front end 30a of the slope 12a on the vehicle body side. Also good. Furthermore, for example, the contact position is arranged at a position behind the imaginary line (vertical line) S passing through the center O of the shaft portion 38 and above the vehicle front end 30a of the slope 12a on the vehicle body side. You may make it install.

  Furthermore, in this embodiment, instead of the slope-side protrusion 46 and the hinge-side protrusion 48, a string function or a cable connected to a side panel or a roof (not shown) is connected to the slope 12a on the vehicle body side to thereby provide a stopper function. You may make it demonstrate.
