Description

[Technical Field]

[0001] This specification discloses a vehicle rear structure in which a back door and a tailgate are provided at the rear of the vehicle. [Background technology]

[0002] For example, in a welfare vehicle, a door that opens both upward and downward is provided as a rear structure, as in Patent Document 1. For example, a back door is provided at the rear of the vehicle as an upward-opening door, and a tailgate is provided as a downward-opening door.

[0003] In Patent Document 1, as illustrated in Fig. 14, for example, an unlocking mechanism 620 is provided on the underside of a back door 520. The unlocking mechanism 620 is provided with a hook 621 that protrudes from an inner surface 520A (the surface facing the passenger compartment) of the back door 520. A locking mechanism 550 is provided on a tailgate 540. The locking mechanism 550 is provided with a pin 630 that protrudes from the upper surface of the tailgate 540.

[0004] When the back door 520 opens upward, the hook 621 abuts against the pin 630, causing the pin 630 to tilt toward the rear of the vehicle. The backward tilt of the pin 630 releases the locking mechanism 550 of the tailgate 540. For example, as illustrated in FIG. 15 , the backward tilt of the pin 630 releases the engagement between the lock unit 546 and the striker 518. Opening the back door 520 and the tailgate 540 makes it easier for a wheelchair to enter the vehicle interior. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2022-365 Summary of the Invention [Problem to be solved by the invention]

[0006] As illustrated in FIG. 14, the hook 621 is protruded forward of the vehicle from the inner surface of the back door 520, so when the back door 520 is in the open state (upward-opening state) as shown in FIG. 15, the hook 621 protrudes downward from the inner surface 520A of the back door 520.

[0007] At this time, when guiding the wheelchair into the vehicle interior, the caregiver pushing the wheelchair from behind must push the wheelchair into the vehicle interior while avoiding the hook 621 protruding downward from the back door 520.

[0008] Therefore, the vehicle rear structure disclosed in this specification aims to enable a caregiver to guide a wheelchair into the vehicle interior without worrying about objects protruding from the back door. [Means for solving the problem]

[0009] The vehicle rear structure disclosed in this specification includes a tailgate and a back door. The back door has a pivot shaft extending in the vehicle width direction at the top of the rear opening of the vehicle body. The tailgate has a pivot shaft extending in the vehicle width direction at the bottom of the rear opening of the vehicle body. A lever capable of unlocking the tailgate from the vehicle body protrudes from the top surface of the tailgate. A U-shaped hook is provided on the underside of the back door. The U-shaped hook protrudes into the vehicle cabin beyond the inner surface of the back door and is hooked onto the lever, causing the lever to tilt rearward when the back door is opened. This U-shaped hook is made of a flexible member.

[0010] According to the above configuration, when the back door is opened, the U-shaped hook protrudes below the inner surface of the back door. Because this U-shaped hook is made of a flexible material, even if the U-shaped hook hits the caregiver's head, the U-shaped hook will bend. This allows the caregiver to guide the wheelchair into the vehicle interior without worrying about the U-shaped hook.

[0011] In the above configuration, the lever may include a protrusion that protrudes forward of the vehicle.

[0012] According to the above configuration, the flexible U-shaped hook is caught on the protrusion, making it possible to prevent the U-shaped hook from coming off the lever.

[0013] In the above configuration, the angle formed by the contact surface of the connection portion that is connected to the protrusion portion from the rotation center side of the lever and that contacts the U-shaped hook and the contact surface of the protrusion portion that contacts the U-shaped hook may be an obtuse angle.

[0014] According to the above configuration, after the lever is pushed down by the U-shaped hook and the locking mechanism of the tailgate is released, the lever can be easily removed from the U-shaped hook.

[0015] In the above configuration, the back surface opposite to the surface of the lever that abuts against the U-shaped hook when the back door is open may be inclined toward the front of the vehicle when the tailgate is locked to the vehicle body.

[0016] When closing an open back door and tailgate, for example, the tailgate is closed first, followed by the back door. When the back door is closed, the U-hook needs to climb over the lever. At this time, the back of the lever is tilted forward, making it easier for the U-hook to climb over the lever. [Effects of the Invention]

[0017] The vehicle rear structure disclosed in this specification allows a caregiver to guide a wheelchair into the vehicle interior without worrying about objects protruding from the back door. [Brief explanation of the drawings]

[0019] FIG. 1 illustrates a vehicle 10 equipped with a vehicle rear structure according to this embodiment. In FIGS. 1 to 13, the longitudinal direction of the vehicle is indicated by an axis represented by the symbol FR, the transverse direction of the vehicle is indicated by an axis represented by the symbol RW, and the vertical direction is indicated by an axis represented by the symbol UP. The symbol FR stands for Front, and the forward direction of the longitudinal axis FR is the positive direction of the vehicle. The symbol RW stands for Right Width, and the right-hand width direction of the transverse axis RW is the positive direction. The height axis UP has the upward direction as its positive direction.

[0020] As shown in FIG. 1, the FR axis, RW axis, and UP axis are perpendicular to one another. Hereinafter, the vehicle rear structure according to this embodiment will be described appropriately based on these three axes. For example, the "front end" refers to the end of any component on the positive side of the FR axis, and the "rear end" refers to the end of any component on the negative side of the FR axis. The "inner side" refers to the inner side of the vehicle width relative to the RW axis, and the "outer side" refers to the outer side of the vehicle width relative to the RW axis. Furthermore, the "upper side" refers to the positive side of the UP axis, and the "lower side" refers to the negative side of the UP axis.

[0021] <Overall structure> 1 and 2, a vehicle 10 equipped with the vehicle rear structure according to this embodiment may be, for example, a welfare vehicle capable of carrying a wheelchair inside the vehicle.

[0022] The vehicle rear structure according to this embodiment includes a back door 20 and a tailgate 40. The back door 20 opens upward and the tailgate 40 opens downward, widening the rear opening 12 of the vehicle 10. This allows a caregiver to easily insert a wheelchair into the vehicle interior 14.

[0023] 2, when the back door 20 is in an open state (upward-opening state), a U-shaped hook 121 of the unlocking mechanism 120 protrudes below an inner door panel 21B, which is an inner panel of the back door 20. As will be described later, the U-shaped hook 121 is made of a flexible material, so even if the U-shaped hook 121 hits the head of the caregiver, the U-shaped hook 121 will simply bend. Therefore, the caregiver can push the wheelchair into the vehicle interior 14 without having to take any action such as avoiding the U-shaped hook 121.

[0024] Furthermore, when the tailgate 40 is in the open state (downward-opening state), the lever cover 131 of the locking mechanism 50 protrudes from the upper end of the tailgate 40 toward the rear of the vehicle. At this time, the protrusion 131C of the lever cover 131 faces upward, as illustrated in Fig. 11. In other words, the protrusion 131C faces the soles of the caregiver's feet.

[0025] As will be described later, the top of the protrusion 131C of the lever cover 131 is rounded, and the protrusion height is approximately the same as the diameter of the U-shaped hook 121. With this structure, the protrusion 131C is prevented from getting caught on the soles of the caregiver's feet, and the caregiver can smoothly push the wheelchair into the vehicle compartment 14.

[0026] <Tailgate> 1 and 2, tailgate 40 is rotatable about a rotation axis L2 provided at the bottom of rear opening 12 of the vehicle body. Rotation axis L2 extends in the vehicle width direction. For example, rotation axis L2 is determined by a hinge mechanism in which a rotation pin (not shown) is inserted between bracket 49 provided at the bottom end of rear opening 12 of the vehicle body and a flange (not shown) provided at the bottom end of door panel 44 of tailgate 40.

[0027] 2, the tailgate 40 is a portion that includes the center portion of the rear bumper (the center portion in the vehicle width direction) and is opened by tilting backward. Therefore, the rear bumper of the vehicle 10 is divided into rear bumpers 19, 19 provided on both sides of the rear surface of the vehicle in the vehicle width direction, and a tailgate bumper 42 provided on the tailgate 40.

[0028] In Figure 2, in order to clarify the position of the striker 18 etc., auxiliary devices such as ramps are not shown inside the vehicle compartment 14, but these auxiliary devices may be provided in the vehicle compartment 14 to make it easier for wheelchair users to board the vehicle.

[0029] The tailgate 40 includes a tailgate bumper 42 , a door panel 44 , a lock unit 46 , a striker 48 , and a lock mechanism 50 .

[0030] The door panel 44 is a plate member extending in the vehicle width direction and the vertical direction, and a weatherstrip 45 is provided on the upper end thereof over the entire length in the vehicle width direction. Furthermore, as will be described later, a lever cover 131 protrudes beyond the weatherstrip 45.

[0031] A lock mechanism 50 and a lock unit 46 are provided on the front surface of the door panel 44. The lock unit 46 is disposed forward and above the front surface of the door panel 44. A pair of lock units 46 are provided on both ends of the tailgate 40 in the vehicle width direction. The lock unit 46 has a slit cut in the front-to-rear direction of the vehicle, for example, on the outer side in the vehicle width direction, and a latch (not shown) is provided inside the lock unit 46.

[0032] A striker 18 for the tailgate 40 is provided on the deck trim side panel 16, which is the side wall at the rear of the passenger compartment 14, particularly the inner wall of the tire house. Although only the striker 18 on the right side of the vehicle is shown in Fig. 2, a striker 18 is also provided on the deck trim side panel 16 on the left side of the vehicle due to the symmetry of the vehicle structure.

[0033] When the tailgate 40 is in a closed state, in other words, when the tailgate 40 is locked to the vehicle body, the latch of the lock unit 46 is engaged with the striker 18. As will be described later, when a lever cover 131, which is an operating lever of the lock mechanism 50, is tilted rearward in the front-to-rear direction of the vehicle, the engagement between the lock unit 46 and the striker 18 is released. This causes the tailgate 40, which is in a closed state, to open downward.

[0034] Referring to Figures 3 to 5, the locking mechanism 50 is a mechanism capable of unlocking the tailgate 40, and is composed of a lever cover 131 which is an operating lever, a lever frame 110, a ball joint 90, an arm 56, a connecting link 58, and a pair of cables 64A, 64B.

[0035] Referring to Figure 3, the locking mechanism 50 is housed in a cover 70. The cover 70 is provided with a cover plate 71, which is a front panel member, and a box-shaped cover tray 72. The cover tray 72 has a cutout at the front of the vehicle. The cover plate 71 has a cutout at its upper end. These cutouts form an opening 73. A lever cover 131 protrudes from the opening 73.

[0036] The unlocking process of the lock mechanism 50 is known from Patent Document 1 and the like, and will be briefly explained below. First, the lever cover 131 is tilted toward the rear of the vehicle, causing the lever frame 110 to be tilted (rotated) toward the rear with the rotation pin 100 as the rotation center as shown in Figure 5. This causes the connecting arm 110C to rotate upward.

[0037] Furthermore, ball joint 90 is pulled up forward and upward in the vehicle width direction along connecting arm 110C. As ball joint 90 is pulled up, flange 56G of arm 56 connected to the lower end of ball joint 90 is urged upward. This causes arm 56 to rotate counterclockwise around rotation pin 60.

[0038] As the arm 56 rotates counterclockwise, the protrusion 56F1 comes into contact with the lower end of the outer arm 58C of the connecting link 58. As the arm 56 continues to rotate counterclockwise, the connecting link 58 also rotates counterclockwise. As a result, the cables 64A and 64B are pulled, and the lock unit 46 (see FIG. 2) is unlocked. That is, the tailgate 40 is unlocked.

[0039] <Lever mechanism> 4 and 5, the locking mechanism 50 includes a U-shaped hook 130 and a lever cover 131 as a lever mechanism. The U-shaped hook 130 is fixed to the lever frame 110 via a hook cover 132. For example, the U-shaped hook 130 is formed by bending a round iron bar.

[0040] A lever cover 131 is placed over the U-shaped hook 130. The lever cover 131 is made of a resin material such as polyacetate. The lever cover 131 is a lever that can unlock the tailgate 40 from the vehicle body. With reference to FIG. 3, the lever cover 131 protrudes from the upper surface 70A of the tailgate 40 (more specifically, of the cover 70). With reference to FIG. 2, the upper end of the lever cover 131 protrudes above the weatherstrip 45.

[0041] Lever cover 131 includes standing portion 131A, inclined portion 131B, and protrusion 131C. The configuration of lever cover 131 will be described below in the standing state illustrated in FIG. 5. Standing portion 131A is a hollow portion that accommodates U-shaped hook 130. Inclined portion 131B is a connection portion that is connected to the upper end of standing portion 131A. Inclined portion 131B (connection portion) is inclined toward the rear of the vehicle relative to standing portion 131A. In addition, inclined portion 131B is a connection portion that is connected to protrusion 131C from the side of rotation pin 100, which is the rotation center of lever cover 131.

[0042] The protrusion 131C protrudes toward the front of the vehicle. The apex of the protrusion 131C is rounded. The protrusion 131C has a tapered structure that widens from the apex. The protrusion height of the protrusion 131C is approximately equal to the diameter of the U-shaped hook 121 (see FIG. 9). Furthermore, as will be described later, the inclined surface 131C1 of the protrusion 131C and the abutment surface 131B1 of the inclined portion 131B form a recessed structure into which the U-shaped hook 121 of the unlocking mechanism 120 is caught.

[0043] For example, the angle formed between the inclined surface 131C1 (contact surface) of the protrusion 131C and the contact surface 131B1 of the inclined portion 131B is an obtuse angle. By setting such an obtuse angle so that the recess structure is widely opened, when the lever cover 131 is tilted backward and the tailgate 40 is in the open state as shown in FIG. 10 , the U-shaped hook 121 can climb over the protrusion 131C and be detached from the lever cover 131.

[0044] When the tailgate 40 and the back door 20 are closed, the tailgate 40 is closed first, and then the back door 20 is closed. When the tailgate 40 is in the closed state (the tailgate 40 is locked to the vehicle body), the lever cover 131 is biased by the return spring 62 (see FIG. 4) and the like, so that the lever cover 131 assumes a forward tilted position as shown in FIG.

[0045] At this time, the rear surface 131A1 of the lever cover 131 is inclined toward the front of the vehicle. The rear surface 131A1 refers to the surface opposite to the abutment surface (abutment surface 131B1 and inclined surface 131C1) of the lever cover 131 that abuts against the U-shaped hook 121 when the back door 20 and the tailgate 40 are opened.

[0046] When the tailgate 40 is closed and then the back door 20 is to be closed, the U-shaped hook 121 of the back door 20 comes into contact with the back surface 131A1 in a forward tilted position, then moves along the back surface 131A1 while bending, and finally climbs over the lever cover 131. As a result, the tip of the U-shaped hook 121 is disposed further forward of the vehicle than the lever cover 131, as illustrated in FIG.

[0047] <Backdoor> 2, 6, and 7, the back door 20 is rotatable about a rotation axis L1 provided at the upper part of the rear opening 12 of the vehicle body. The rotation axis L1 extends in the vehicle width direction. For example, the rotation axis L1 is determined by a hinge mechanism (not shown) provided at the upper end of the rear opening 12 of the vehicle body and the upper end of the back door 20.

[0048] The back door 20 includes an outer door panel 21A, which is a panel material that is exposed to the outside of the vehicle, and an inner door panel 21B, which is a panel material inside the vehicle. A door handle 24 is provided on the outer door panel 21A. By operating the door handle 24 to open, the lock unit 22 is released from the striker 48, and the back door 20, which is in a closed state, transitions to an open state. The connecting structure between the door handle 24 and the lock unit 22 is known, so a description thereof will be omitted here.

[0049] 8, the door panel inner 21B extends in the vehicle vertical direction, and its lower end is bent toward the rear of the vehicle to form an L-shape in a side view. Referring to FIG. 2, the lock unit 22 and the unlocking mechanism 120 are provided on a lower surface 21B1, which is the lower end portion of the door panel inner 21B.

[0050] The lock unit 22 is engageable with a striker 48 provided on the upper surface of the cover 70 of the tailgate 40. An unlocking mechanism 120 is provided adjacent to the lock unit 22 in the vehicle width direction. Referring to Figure 7, the unlocking mechanism 120 includes a U-shaped hook 121, a bracket 122, and a plate 123.

[0051] The U-shaped hook 121 is made of a flexible member such as a resin wire. With reference to FIGS. 6 and 7, the U-shaped hook 121 is provided on the underside 21B1 of the back door 20. When the back door 20 is closed (in other words, when the back door 20 is in an upright position), the U-shaped hook 121 protrudes into the vehicle cabin from the inner surface 21B3 (see FIG. 8), which is a vertical surface of the inner door panel 21B. In other words, when the back door 20 is open (in an upward-open state), the U-shaped hook 121 of the unlocking mechanism 120 protrudes below the inner door panel 21B.

[0052] Here, since the U-shaped hook 121 is made of a flexible material as described above, even if the U-shaped hook 121 hits the head of the caregiver, the U-shaped hook 121 will simply deform. Therefore, the caregiver can push the wheelchair into the vehicle compartment 14 without having to take any action such as avoiding the U-shaped hook 121.

[0053] The bracket 122 is a fixing member that fixes the U-shaped hook 121 and the plate 123 to the lower surface 21B1 of the door panel inner 21 B. The bracket 122 includes a main body 122A, an inclined plate 122B, and a flange 122C.

[0054] A pair of flanges 122C are provided on both ends of the main body 122A in the vehicle width direction. Fastening holes 122C1 are drilled in the flanges 122C in the thickness direction and are aligned with fastening holes 21B2 provided in the lower surface 21B1 of the door panel inner 21B. Furthermore, the bracket 122 is fixed to the lower surface 21B1 of the door panel inner 21B by tightening bolts and nuts.

[0055] An inclined plate 122B is provided at the tip of the main body 122A. When the back door 20 is closed, the inclined plate 122B is disposed so as to protrude further into the vehicle cabin than the inner door panel 21B. Furthermore, when the back door 20 is closed, the inclined plate 122B is disposed so as to be inclined downward relative to the main body 122A and extend forward and downward of the vehicle.

[0056] The U-shaped hook 121 is sandwiched between a plate 123 and a bracket 122. The plate 123 includes a main body 123A and an inclined plate 123B. The main body 123A faces a main body 122A of the bracket 122 with the U-shaped hook 121 sandwiched therebetween.

[0057] When the back door 20 is closed, the inclined plate 123B is disposed so as to protrude further into the vehicle interior than the door panel inner 21B. The inclined plate 123B is also positioned so as to be parallel to the inclined plate 122B of the bracket 122. In other words, the inclined plate 123B is disposed so as to be inclined downward relative to the main body portion 122A and extend forward and downward of the vehicle.

[0058] The flexible U-shaped hook 121 sandwiched between the inclined plates 122B, 123B is oriented along the inclined plates 122B, 123B. That is, when the back door 20 is closed, the U-shaped hook 121 is positioned so as to be inclined downward and forward of the vehicle. By inclining downward in this manner, the U-shaped hook 121 becomes more likely to catch on the lever cover 131.

[0059] <Back door and tailgate opening operation> When the door handle 24 of the back door 20 (see FIG. 2) is manually operated to open, the lock unit 22 is disengaged from the striker 48. Accordingly, the back door 20 is lifted upward around the rotation axis L1.

[0060] 8 and 9, at this time, at the lower end of the back door 20, the lever cover 131 in a forward tilting position is positioned on the trajectory of the U-shaped hook 121. Therefore, the U-shaped hook 121 is caught on the lever cover 131 during the process of opening the back door 20.

[0061] As described above, the protrusion 131C and the inclined portion 131B are provided on the front surface (the surface facing the U-shaped hook 121) of the lever cover 131. The U-shaped hook 130 is caught in the recess formed by the inclined surface 131C1 of the protrusion 131C and the abutting surface 131B1 of the inclined portion 131B, thereby preventing the U-shaped hook 121 from coming off the lever cover 131.

[0062] When the lever cover 131 hooked on the U-shaped hook 121 is tilted backward and the engagement between the lock unit 46 (see FIG. 2) and the striker 18 is released, the tailgate 40 opens downward as shown in FIG. 10. If the lever cover 131 is then tilted and, for example, the inclined surface 131C1 of the protrusion 131C is tilted further rearward from the position perpendicular to the horizontal plane, the U-shaped hook 121 comes off the protrusion 131C. Thereafter, the back door 20 and the tailgate 40 unfold without interfering with each other.

[0063] <Back door closing operation> When the back door 20 and tailgate 40 are brought from an open state to a closed state, the tailgate 40 is first closed, for example, manually. As shown in FIG. 8 described above, when the tailgate 40 is in the closed state, the back surface 131A1 of the lever cover 131 is in a forward tilted position. When the back door 20 is closed, the flexible U-shaped hook 121 climbs over this back surface 131A1. As a result, the folded portion of the U-shaped hook 121 is positioned forward of the lever cover 131.

[0064] 12 and 13 show another example of lever cover 131 according to this embodiment. When lever cover 131 is in the upright position as shown in FIGS. 12 and 13, lever cover 131 has first protrusion 131D at the upper end of upright portion 131A. Connecting portion 131E is connected to the upper end of first protrusion 131D. Furthermore, second protrusion 131F is connected to the upper end of connecting portion 131E.

[0065] 13, holding claws 131G, 131G for holding the U-shaped hook 130 of the locking mechanism 50 are provided on the rear surface of the lever cover 131 (the surface that does not come into contact with the U-shaped hook 121).

[0066] 12, the first protrusion 131D and the second protrusion 131F protrude further forward than the connecting portion 131E. That is, a recess is formed by the first protrusion 131D, the connecting portion 131E, and the second protrusion 131F. When the back door 20 is opened, the U-shaped hook 121 is hooked into this recess.

[0067] Furthermore, when the tailgate 40 is in the closed state, the back surface 131A1 (see FIG. 13) of the lever cover 131 is inclined forward. When the back door 20 is closed, the flexible U-shaped hook 121 climbs over this back surface 131A1. As a result, the folded portion of the U-shaped hook 121 is disposed forward of the lever cover 131. [Explanation of symbols]
