Description

  The present invention relates to a vehicle door that can perform a smooth getting-off operation by reducing interference between a foot portion and a door when an occupant gets off.

  2. Description of the Related Art Conventionally, a door pocket or the like for storing a beverage bottle, a small baggage, or the like is provided on a door trim disposed on a vehicle compartment side of a vehicle door. For example, as in Patent Document 1, the door pocket is provided in the lower portion of the door trim below the door armrest. Moreover, the door pocket is formed by providing a bottom portion and an opposing wall portion on a recessed wall portion in which a door trim is recessed on the vehicle exterior as in Patent Document 2.

  Further, the vehicle door is provided with a speaker housing portion for housing a speaker for outputting sound such as in-vehicle audio. Since the occupant does not touch the speaker to perform an operation or the like, the speaker accommodating portion is often provided on the lower side of the door trim that cannot be reached when the occupant is seated on the seat.

  As described above, the door trim is formed so as to advance toward the passenger compartment side in order to provide the storage portion for the luggage and the speaker storage portion on the lower side thereof, so that the thickness of the vehicle door increases and the vehicle door is opened. The opening on the side of the vehicle is narrow.

  When the occupant opens the vehicle door and gets off the vehicle, the lower limbs on the door side are first taken out of the vehicle and the legs are landed to move the upper body. However, since the opening on the side surface of the vehicle when the door is opened is narrow due to the thickness of the vehicle door, the operation up to the landing of the foot may not be smooth, which is not preferable.

  On the other hand, the movement to the landing of the foot when getting off includes the rotational movement of the thigh. The present inventor has found that the rotational movement of the thigh has a rotation angle range that is difficult to rotate. The rotation angle range corresponds to an operation in which the occupant moves the foot part out of the vehicle beyond the side sill of the vehicle from the passenger compartment. Therefore, since it is difficult to perform the operation as intended by the occupant, the side sill, the door trim, and the foot are likely to interfere with each other, and the occupant may not be able to get off smoothly.

  An object of the present invention is to provide a vehicle door that can smoothly get off.

According to the first aspect of the present invention, the front end portion is hinged to the pillar portion of the vehicle so that the side opening of the vehicle can be opened and closed, and the luggage is accommodated in the lower part of the vehicle compartment side below the armrest and the armrest. In the vehicle door provided with a section, an occupant with a standard physique seated on the seat surface portion with the hip point set at the center in the vehicle width direction of the rear portion of the seat surface portion of the seat adjacent to the vehicle door as a rotation center When the thigh of the lower limb is rotated to move the bent lower limb on the vehicle door side out of the vehicle when the vehicle door is opened and the vehicle gets off, the vehicle door side near the lower end of the vehicle door The part is provided with an interference mitigation concave part in which a part of the lower part of the housing part on the vehicle compartment side is recessed to the outside of the vehicle so as not to interfere with the leg part of the lower limb.

According to the above configuration, when the vehicle door with the front end hinged is opened and the occupant gets off, the lower leg thigh of the vehicle door side is rotated to the vehicle door side around the hip point. Ru is. At this time, in order to avoid a collision between the foot part that moves together with the thigh and the vehicle door, a part of the vehicle compartment side below the luggage storage part below the armrest of the vehicle door is Since the interference reducing recess that is recessed outward is provided, it is possible to reduce the interference between the vehicle door and the foot while suppressing a decrease in the capacity of the housing .

  According to a second aspect of the present invention, in the first aspect, the interference reducing recess has a predetermined intermediate opening when the rotation angle when the thigh is parallel to the longitudinal direction of the vehicle is 0 °. The vehicle door is provided at a portion corresponding to a predetermined rotation angle range of the thigh having at least 50 ° as a center.

  According to the above configuration, when the vehicle door is set to a predetermined intermediate opening, the vehicle door corresponding to a predetermined rotation angle range of the thigh having at least 50 ° as a center, which is difficult to rotate the thigh. Since the interference reducing recess is provided in the portion, the interference between the vehicle door and the foot can be reduced. Moreover, since the capacity | capacitance reduction of the accommodating part by an interference reduction recessed part is restricted to the predetermined | prescribed rotation angle range, the capacity | capacitance reduction of an accommodating part can be suppressed.

  According to a third aspect of the present invention, in the second aspect of the present invention, the interference reducing recess is provided such that a portion corresponding to the center of the rotation angle range is a concave top.

  According to the above configuration, since the interference reduction recess is provided so that the portion corresponding to the angle at which the thigh at the center of the rotation angle range is difficult to rotate is the most recessed top of the interference reduction recess, Interference between the vehicle door and the foot can be reduced.

  According to the vehicle door of the present invention, it is possible to reduce the interference with the foot when the occupant gets off, and to get off smoothly.

It is a top view of a vehicle. It is a side view of the vehicle except for the door for vehicles. It is a top view of the vehicle interior side of the vehicle door on the right side of the front seat in the embodiment of the present invention.

A right front seat 6a, a left front seat 6b, and a rear seat 7 are disposed in the passenger compartment, and a passenger can be seated on these seats. Since the vehicle 1 has a substantially symmetrical structure, the right side portion of the vehicle 1 will be described, and the left side portion of the vehicle 1 will not be described.

  The side opening 2 on the right side of the vehicle 1 includes a hinge pillar 10 (pillar portion) provided upright at the front end portion of the side sill 5, a front pillar 11 that extends upward and rearward from the upper end portion of the hinge pillar 10, and a front pillar. 11 is surrounded by a roof side rail 12 that extends rearward from the rear end portion of the vehicle 11 and a rear pillar 13 that is erected on the rear end portion of the side sill 5 and connected to the rear end portion of the roof side rail 12. A center pillar 14 that is erected and connected to an intermediate portion of the roof side rail 12 is partitioned forward and backward.

  The front seat right door 3a is hinged at the front end to the hinge pillar 10 (pillar portion), and can be opened and closed by rotating around the axis of the hinge coupling. Further, a door checker 16 connected to the hinge pillar 10 is provided at the front end portion of the front seat right door 3a so as to be maintained at a predetermined intermediate opening or fully opened position. At the rear end portion of the front right door 3a, a door locker 15 (see FIG. 3) is engaged with a door striker (not shown) provided on the center pillar 14 to keep the front right door 3a closed. Is provided. Similarly, the front right portion of the rear seat right door 3c is hinged to the center pillar 14 so that the rear compartment of the center pillar 14 can be opened and closed.

Next, the front door right door 3a will be described as an example of the vehicle door with reference to FIGS.
The front seat right door 3a has a main body portion 20 and a sash portion 21 on the upper side thereof, and a window glass 22 is disposed in a window portion surrounded by the main body portion 20 and the sash portion 21 so as to be opened and closed. On the vehicle compartment side of the main body 20, a door inner handle 23 for releasing the door lock by the door locker 15, an armrest 24, an operation portion 25 for performing an opening / closing operation of the window glass 22, etc., and a handle for closing the door A handle portion 26 and the like are provided, and these are disposed on the upper portion of the main body portion 20 so as to be easily operated by a passenger. In addition, the lower part of the main body part 20 includes a speaker accommodating part 27 that can accommodate a speaker 27a, a door pocket part 28 that can accommodate luggage such as a beverage bottle, and the like.

  The main body 20 includes a door outer panel 31, a door inner panel 32, and a door trim 33 in order from the outside of the vehicle. The opening provided in the door inner panel 32 for work is covered with a panel member 32a. The door trim 33 is formed so as to advance from the door inner panel 32 to the vehicle compartment side, and a speaker housing portion 27 and a door pocket portion 28 are provided between the door inner panel 32 and the door trim 33.

  The speaker 27 a accommodated in the speaker accommodating portion 27 is attached to the door inner panel 32, and the vehicle interior side is covered with the door trim 33. A portion of the door trim 33 facing the speaker 27a is provided with a plurality of holes for allowing sound output from the speaker 27a to pass. Note that an opening may be formed in a portion of the door trim 33 facing the speaker 27a, and a mesh-shaped cover member may be disposed in the opening.

  The door pocket portion 28 has a recessed portion 34 in which the door trim 33 is formed in a recessed shape on the door inner panel 32 side, and a wall portion 35 formed by extending from the lower end portion of the door trim 33 toward the vehicle compartment side and bending upward. A pocket-shaped member 36 is disposed between them. The door pocket portion 28 can also be formed by attaching a member to be a bottom portion and a wall portion to the door trim 33 or integrally molding with the door trim 33. The vicinity of the lower end of the door inner panel 32 and the vicinity of the lower end of the door trim 33 are formed in a shape that follows the stepped shape of the side sill 5 when the front seat right door 3a is closed.

Next, based on FIG. 5 and FIG. 6, the rotational movement of the thigh at the time of getting off will be described by taking the occupant of the right front seat 6a as an example.
A standard occupant seated on the seat portion 40 of the right front seat 6a, when opening the front seat right door 3a, gets out of the vehicle with the bent right lower leg 41 on the front seat right door 3a side. While lifting the thigh 42, it is rotated and moved outward. The foot portion 44 that is the portion of the right lower limb 41 beyond the ankle is connected to the thigh portion 42 via the crus portion 43 and moves together with the rotational movement of the thigh portion 42. The front right door 3a in the open state is farther away from the side opening 2 toward the rear side, and the space between the door trim 33 and the side sill 5 becomes wider.

  The rotational movement of the thigh 42 is performed with the hip point HP set at the center in the vehicle width direction of the rear portion of the seating surface 40 as the rotation center, and the thigh 42 is parallel to the front-rear direction of the vehicle 1 in plan view. The rotation angle θ in this state is set to 0 °, and the entire foot portion 44 is rotated and moved until it comes out of the side sill 5 and can land. The standard physique is, for example, the average physique of an adult male, and the length of the thigh 42 (the length from the butt to the knee of the occupant in the sitting position) is about 650 to 700 mm. In addition, the foot 44 may be landed with the lower leg 43 inwardly rotated in the direction opposite to the rotational direction of the thigh 42, and the rotation angle θ of the thigh 42 at the time of landing is compared with the case where the foot 44 is not inwardly rotated. Becomes smaller.

  At this time, the thigh 42 rotates and moves within the range of motion of the hip joint. When the joint passive resistance, which is an index of difficulty in moving the hip joint, is measured in accordance with the getting-off operation, the joint passive resistance increases as the rotation angle θ increases. The value of increases. In the vicinity of the rotation angle θ = 50 °, the value of the joint passive resistance reaches a peak and becomes larger than a predetermined comfort threshold L0 that does not feel difficult to move. When the thigh 42 is further rotated, the space between the door trim 33 and the side sill 5 becomes wider, and interference between the door trim 33 and the foot 44 hardly occurs. As a result, the occupant can move the thigh 42 downward or upward so that the occupant can rotate and move in a comfortable posture, so the value of the joint passive resistance is reduced. As described above, the occupant feels difficulty in rotational movement in the vicinity of the rotational angle θ = 50 ° at which the value of the joint passive resistance is larger than the comfort threshold L0 when the thigh 42 is rotationally moved. Further, since it is difficult to rotate and move, the vehicle cannot rotate as intended by the passenger, and the foot 44 and the door trim 33 may collide and interfere with each other, which may hinder smooth getting-off operation.

  Further, the degree of interference between the foot and the vehicle door when getting off differs depending on the opening degree of the vehicle door. For example, when the front seat right door 3a is fully opened, the space between the side sill 5 and the door trim 33 is sufficiently large even if the opening is narrowed by the thickness of the front seat right door 3a. For this reason, interference between the foot portion 44 and the door trim 33 that moves with the rotational movement of the thigh 42 is unlikely to occur, but there are not many cases where the front seat right door 3a and the like can be fully opened.

  On the other hand, the predetermined intermediate opening maintained by the door checker 16 depends on the vehicle width of the vehicle 1, the size of the front seat right door 3a, etc. when parking in a parking space having a general width (for example, 2300 mm). Accordingly, the opening is set so as not to collide with a parked vehicle in an adjacent parking space. The predetermined intermediate opening is set to, for example, 30 ° for the front right seat door 3a and 35 ° for the rear right seat door 3c, when the vehicle door is closed at 0 °. It is considered that the occupant is most likely to get off at this predetermined intermediate opening, and the interference between the foot 44 and the door trim 33 does not occur due to the rotational movement of the thigh 42, but the interference between the foot 44 and the door trim 33 does not occur. It is a situation that occurs.

  In order to reduce such interference between the foot portion 44 and the door trim 33, as shown in FIGS. 3 to 5, in the vicinity of the lower end of the door trim 33 of the front seat right door 3 a corresponding to the vicinity of the lower end of the vehicle door on the passenger compartment side. The vehicle interior side portion (the portion facing the wall portion 35 of the door pocket portion 28 and the speaker 27a of the speaker housing portion 27) of the door trim 33 that has been advanced toward the vehicle interior side is recessed into the vehicle exterior in at least a part of the portion. The interference reducing recess 38 is provided. The interference reducing recess 38 is formed in a substantially arc shape having a concave top in the vertical direction of the door trim 33, and in a substantially arc shape having a concave top in the door thickness direction from the door trim 33 toward the door inner panel 32. Is formed. The vertical position of the interference reducing recess 38 and the vertical position of the door in the thickness direction coincide with each other.

  The interference reducing recess 38 is formed at a position corresponding to at least a predetermined rotation angle range of the thigh 42 when the front seat right door 3a has a predetermined intermediate opening. The predetermined rotation angle range is 45 ° to 55 ° including a range exceeding at least the comfort threshold L0 with the rotation angle θ = 50 ° of the thigh 42 having the peak as a center based on the joint passive resistance. The range is preset. And it is provided so that the concave top may coincide with the position corresponding to the rotation angle θ = 50 ° of the thigh 42 where the value of the joint passive resistance becomes a peak.

The operation and effect of the present invention will be described.
For example, when the occupant of the right front seat 6a gets off, the thigh 42 of the bent right lower leg 41 on the front seat right door 3a side is rotated and moved to the front seat right door 3a side around the hip point HP. At this time, it is possible to reduce interference with the door trim 33 by causing a part (for example, a toe portion) of the foot portion 44 to enter the interference reducing recess 38 formed in the vicinity of the lower end of the door trim 33 of the front seat right door 3a. it can.

  Further, when the front seat right door 3a is set to a predetermined intermediate opening, at least 50 ° including a rotation angle range in which at least the thigh 42 of the door trim 33 is difficult to rotate and move is determined at a predetermined thigh. An interference reducing recess 38 is provided in a portion corresponding to the rotation angle range. Therefore, interference between the door trim 33 and the foot 44 can be reduced within a rotation angle range in which the thigh 42 is difficult to rotate. Moreover, since the capacity | capacitance reduction of the speaker accommodating part 27 and the door pocket part 28 by the interference reduction recessed part 38 is restricted to the rotation angle range, those capacity | capacitance reductions can be suppressed.

  In addition, the interference reducing recess 38 is provided such that a portion corresponding to the center of the rotation angle range is a concave top. Therefore, it is possible to reduce the interference between the door trim 33 and the foot portion 44 by maximizing the space where the foot portion 44 can enter at the portion corresponding to the center of the rotation angle range in which the thigh portion 42 is most difficult to rotate.

  Although the front seat right door 3a has been described as an example, the rear seat right door 3c can be similarly provided with a recess corresponding to the interference reducing recess 38. Further, since the vehicle 1 has a symmetrical structure, a similar recess can be provided in the front seat left door 3b and the rear seat left door 3d, and the foot and door trim when the passenger of the seat adjacent to these doors gets off. Smooth dismounting operation is possible by reducing the interference.

  The interference reducing recess 38 is recessed toward the door inner panel 32 by the pressure received from the foot 44 by the contact portion of the door trim 33 that the foot 44 contacts with the movement of the foot 44 accompanying the rotational movement of the thigh 42. It may be formed to enter. The interference between the foot 44 and the door trim 33 can be reduced, and the aesthetic appearance can be improved because the concave shape is not visible when there is no interference.

  In addition, those skilled in the art can implement the invention by adding various modifications to the embodiment without departing from the spirit of the invention, and the invention includes such modifications.
