Description

[Technical Field]

[0001] The present invention relates to a utility vehicle. [Background technology]

[0002] For example, the multipurpose vehicle disclosed in Patent Document 1 is equipped with shoulder guards (referred to as "protective panels" in the document) in a position corresponding to the upper part of the backrest of the passenger seat. Even when centrifugal force is applied laterally to the body of the vehicle when the multipurpose vehicle turns, the passenger in the passenger seat is supported by the shoulder guards on the side. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-174966 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, in the multipurpose vehicle disclosed in Patent Document 1, the shoulder guards are fixed to the frame of the vehicle body, which narrows the width of the boarding and disembarking space in the fore-and-aft direction of the vehicle body, and passengers may feel cramped when getting in and out of the seat.

[0005] An object of the present invention is to provide a multipurpose vehicle that can support a passenger in a passenger seat with the side portions and allows the passenger to easily get on and off. [Means for solving the problem]

[0006] The multipurpose vehicle of the present invention is characterized in that it comprises a driver's section in which a passenger sits, a passenger seat provided in the driver's section and having a seat on which the passenger can sit and a backrest provided at the rear of the seat, and a boarding door that opens and closes the boarding and alighting opening for the driver's section, and that the upper part of the boarding and alighting door is provided with a shoulder guard section that extends in the vertical direction to a position corresponding to the upper part of the backrest, and a frame body that extends vertically is attached to the shoulder guard section.

[0007] According to the present invention, the upper part of the boarding door extends to a position corresponding to the upper part of the seat back, functioning as a shoulder guard. Therefore, even when centrifugal force is applied laterally to the vehicle body when the multipurpose vehicle turns, a passenger in the boarding seat is received by the upper part of the boarding door. Furthermore, the configuration in which the vertically extending frame body is attached to the upper part of the boarding door (shoulder guard part) makes the boarding door less susceptible to deformation compared to a configuration in which the frame body is not attached to the shoulder guard part, and the upper part of the boarding door can firmly receive the passenger. Furthermore, the configuration in which the boarding door has a shoulder guard part at its upper part eliminates the need to fasten the shoulder guard to the vehicle frame, making it easier to ensure a wide boarding and alighting space in the fore-and-aft direction of the vehicle. Thus, the present invention realizes a multipurpose vehicle in which the side parts of the boarding seat receive passengers and allow passengers to easily board and alight.

[0008] In the present invention, it is preferable that the frame body be attached to an inner surface portion of the shoulder guard portion that faces the driver's portion.

[0009] This configuration eliminates the irregular appearance of the multi-purpose vehicle compared to a configuration in which the frame body is attached to the outer surface of the shoulder guard portion.

[0010] In the present invention, the frame body has an upper and lower extension portion that extends vertically, and a horizontal extension portion that extends from the upper part of the upper and lower extension portion in the front-to-rear direction when the boarding / alighting door is closed, and it is preferable that the inner surface portion has a recess that recesses into the side where the outer surface portion is located in accordance with the shape of the upper and lower extension portion and the horizontal extension portion, and the frame body is attached to the recess.

[0011] With this configuration, the frame body is housed in the recess, which reduces the degree to which the frame body protrudes from the driver's section. That is, with this simple configuration, the shoulders of the passenger are less likely to come into contact with the frame body.

[0012] In the present invention, the driver's section is provided with a seat frame that supports the passenger seat, and a locking mechanism that can hold the boarding door in a closed position, and it is preferable that the locking mechanism has a first engagement portion attached to the seat frame, a second engagement portion attached to a lower part of the frame body, and a single operating tool that can operate the first engagement portion or the second engagement portion to switch the first engagement portion and the second engagement portion between an engaged state and a disengaged state.

[0013] This configuration allows the locking mechanism to hold the door in place, and the passenger can release the locking mechanism by operating a single operating tool, allowing the door to be opened or closed.

[0014] In the present invention, it is preferable that an opening is formed in the boarding / alighting door, penetrating from the inner surface facing the driver's unit to the outer surface opposite the side on which the driver's unit is located, and that the single operating device is positioned in the opening.

[0015] With this configuration, a single operating device is placed at the opening of the entry / exit door. This allows passengers to operate the single operating device from both inside and outside the vehicle. Furthermore, compared to a configuration in which operating devices are provided on both the inside and outside of the entry / exit door, only one operating device is required, which reduces the number of parts.

[0016] In the present invention, it is preferable that the frame body be provided with an abutment portion that abuts against the seat frame at a location below the second engagement portion.

[0017] According to this configuration, the abutment portion is configured to be able to abut against the seat frame. The second engagement portion engages with the first engagement portion, and when the boarding door is closed, the second engagement portion holds the boarding door in position. When a passenger leans their shoulders against the shoulder guard portion at the top of the boarding door, the upper part of the frame body is pushed outward to the side of the aircraft. If the frame body swings around the second engagement portion at this time, it is possible that the upper part of the boarding door will be displaced outward to the side of the aircraft. With this configuration, the abutment portion is provided on the frame body at a location below the second engagement portion, and the abutment portion abuts against the seat frame. With this configuration, even if the frame body tries to swing around the second engagement portion, the abutment portion at the bottom of the boarding door will be pressed against the seat frame. This makes it less likely that the upper part of the boarding door will be displaced outward to the side of the aircraft.

[0018] In the present invention, it is preferable that the frame body and the seat frame are respectively formed with planar portions facing each other, and the abutment portion is attached to the planar portions of the frame body.

[0019] With this configuration, even if the frame body attempts to swing around the second engaging portion so that the upper part of the frame body is displaced laterally outward, the seat frame can firmly receive the lower part of the boarding door, making it even more difficult for the upper part of the boarding door to be displaced.

[0020] In the present invention, it is preferable that the contact portion is made of an elastic body.

[0021] With this configuration, for example, when the boarding door is closed, the impact caused when the contact portion and the seat frame come into contact with each other is alleviated. [Brief explanation of the drawings]

[0023] An embodiment of the present invention will be described with reference to the drawings. In the following description, unless otherwise specified, the direction of arrow F in the drawings will be referred to as "front," the direction of arrow B as "rear," the direction of arrow L as "left," and the direction of arrow R as "right." Furthermore, the direction of arrow U in the drawings will be referred to as "up," and the direction of arrow D as "down."

[0024] [Overall configuration of multipurpose vehicle] The multipurpose vehicle of this embodiment will be described below. As shown in Fig. 1, the multipurpose vehicle is equipped with a traveling body 1, a hood 2, a driver's section 3 where a passenger sits, and a dump-type cargo bed 4. The traveling body 1 is equipped with a body frame 5 and a traveling device 6. Although not shown, the multipurpose vehicle is equipped with a water-cooled engine and a transmission, and the power of the engine is changed in speed by the transmission and transmitted to the traveling device 6. Note that the multipurpose vehicle may also be an electric multipurpose vehicle equipped with an electric motor for traveling.

[0025] The traveling device 6 includes steerable and drivable left and right front wheels 6F and non-steerable and drivable left and right rear wheels 6B. The traveling device 6 is configured to be switchable between a two-wheel drive state in which only the left and right rear wheels 6B are driven, and a four-wheel drive state in which the left and right front wheels 6F and the left and right rear wheels 6B are driven.

[0026] The driver's section 3 includes a steering wheel 7, a driver's seat 10, an auxiliary seat 11, a rear seat 12, a safety lock 13 for passenger protection, left and right front boarding / alighting doors 14, and left and right rear boarding / alighting doors 15. The cargo bed 4 is located behind the driver's section 3. The front boarding / alighting doors 14 and rear boarding / alighting doors 15 open and close the driver's section 3. The driver's seat 10 and auxiliary seat 11 are each supported by a seat frame 17. The safety lock 13 has center pillars 13A on both the left and right sides of the center portion between the front and rear. The rear boarding / alighting doors 15 are supported at the bottom of the left and right center pillars 13A so that they can swing open and close. The front boarding / alighting doors 14 correspond to the "boarding / alighting doors." The driver's seat 10, auxiliary seat 11, and rear seat 12 correspond to the "passenger seats."

[0027] The control unit 7 is equipped with various operating tools such as a steering handle for steering the left and right front wheels 6F, an accelerator pedal for adjusting the driving speed, a brake pedal for braking, and a gear shift lever for changing gears.

[0028] A passenger who drives (hereinafter referred to as the "driver") sits in the driver's seat 10. The auxiliary seat 11 is adjacent to and alongside the driver's seat 10. The driver's seat 10 is provided on the left side in the left-right direction of the aircraft body, and the auxiliary seat 11 is provided on the right side in the left-right direction of the aircraft body.

[0029] The driver's seat 10 has a seat portion 10A on which a passenger can sit, a backrest portion 10B provided at the rear of the seat portion 10A, and a headrest 10C supported by the backrest portion 10B. The driver's seat 10 is configured to be slidable in the front-to-rear direction. This allows the passenger sitting in the driver's seat 10 to adjust the position of the seat in the front-to-rear direction. The driver's seat 10 is also configured so that the angle of the backrest portion 10B is adjustable. This allows the passenger sitting in the driver's seat 10 to adjust the reclining angle of the backrest portion 10B.

[0030] In this embodiment, the auxiliary seat 11 is configured to accommodate two passengers. The auxiliary seat 11 has a seat portion 11A that can accommodate two passengers, a backrest portion 11B provided at the rear of the seat portion 11A, and two headrests 11C supported by the backrest portion 11B. The auxiliary seat 11 is configured so that the angle of the backrest portion 11B can be adjusted. Therefore, the passenger sitting in the auxiliary seat 11 can adjust the reclining angle of the backrest portion 11B.

[0031] In this embodiment, the rear seat 12 is configured to accommodate three passengers. The rear seat 12 has a seat portion 12A that can accommodate three passengers, a backrest portion 12B provided at the rear of the seat portion 12A, and three headrests 12C supported by the backrest portion 12B.

[0032] [Front door configuration] As shown in Figures 1 and 2, each of the left and right front entry / exit doors 14 is provided with a door body 14A. A hinge portion 14C is connected to the front portion of the door body 14A. The hinge portion 14C is connected to the front portion of the ROPS 13. The hinge portion 14C has a swing axis that extends vertically, and the door body 14A swings around the swing axis of the hinge portion 14C. As shown in Figure 1, when the front entry / exit doors 14 are closed, the free end of the door body 14A overlaps with the center pillar 13A over both the upper and lower ends in a side view of the aircraft body.

[0033] As shown in FIG. 3, the door body 14A is formed with an inner surface 14D facing the driver's section 3 and an outer surface 14E on the side opposite to the side where the driver's section 3 is located.

[0034] The upper part of door body 14A extends up to a position corresponding to the upper part of seat backs 10B and 11B in the vertical direction. As a result, even when centrifugal force is applied to the left when the multipurpose vehicle turns right, the shoulder of the passenger sitting in driver's seat 10 is received by the upper part of door body 14A of front boarding / alighting door 14 on the left side of the vehicle body.

[0035] Moreover, even when centrifugal force is applied to the right when the multipurpose vehicle turns left, the shoulders of the passenger sitting on the auxiliary seat 11 or the cargo placed on the seat part 11A of the auxiliary seat 11 are received by the upper part of the door body 14A of the front boarding / alighting door 14 on the right side of the vehicle body.

[0036] In this way, the upper portion of the door body 14A of each front getting-in / out door 14 functions as a so-called shoulder guard. That is, the front getting-in / out door 14 is provided with a shoulder guard portion 14B that extends up to a position corresponding to the upper portion of the backrest portions 10B, 11B in the vertical direction. The shoulder guard portion 14B has a front-to-rear width equivalent to the width from the front end to the rear end of the sliding range of the driver's seat 10 in the fore-and-aft direction.

[0037] The door body 14A, including the shoulder guard portion 14B, is made of resin, such as polyvinyl chloride or fiber-reinforced plastic. Therefore, it is necessary to consider the rigidity of the door body 14A when the door body 14A receives a load from the shoulder of a passenger or cargo in the lateral outward direction of the aircraft. In this embodiment, a frame body 14F is provided in the shoulder guard portion 14B of the door body 14A to reinforce the door body 14A. The frame body 14F is attached to a portion of the front boarding / alighting door 14 opposite the side where the hinge portion 14C is located, across the opening 14h.

[0038] The frame body 14F is attached to an inner surface 14D of the door body 14A that faces the driver's section 3. The inner surface 14D to which the frame body 14F is attached is configured as a shoulder guard section 14B.

[0039] The frame body 14F has a vertical extension portion 20, a horizontal extension portion 21, and a planar portion 22. The vertical extension portion 20 extends vertically. The horizontal extension portion 21 extends in the front-to-rear direction from the upper end of the vertical extension portion 20. In other words, the upper portion of the vertical extension portion 20 is bent, and the horizontal extension portion 21 extends in the front-to-rear direction from the upper portion of the vertical extension portion 20. Note that the front-to-rear direction means the front-to-rear direction when the front boarding / alighting door 14 is closed. The planar portion 22 is connected to the lower end of the vertical extension portion 20 by welding.

[0040] A recess 14G is formed in the inner surface portion 14D. The recess 14G is recessed into the side where the outer surface portion 14E is located, following the shapes of the vertical extension portion 20, the horizontal extension portion 21, and the planar portion 22. The frame body 14F is attached to the recess 14G. This allows the inner lateral portion of the frame body 14F to be recessed laterally outward of the body relative to the inner surface portion 14D. Furthermore, even if the inner lateral portion of the frame body 14F protrudes toward the driver's section 3 relative to the inner surface portion 14D, the degree of protrusion is reduced compared to a configuration in which the recess 14G is not formed in the frame body 14F.

[0041] To specifically explain the configuration in which the frame body 14F is attached to the door body 14A, an attachment portion 25 is formed on each of the planar portion 22 and the extending tip end of the laterally extending portion 21. The attachment portion 25 has a hole for inserting, for example, a bolt or a clip. A bolt or a clip is inserted into each of the attachment portions 25 of the planar portion 22 and the laterally extending portion 21, and the bolt or clip is fixed to the recess 14G of the door body 14A. In this way, the frame body 14F is attached and fixed to the door body 14A.

[0042] The multipurpose vehicle of this embodiment is provided with a locking mechanism 16 for the front entry / exit door 14. The locking mechanism 16 is a mechanism that can hold the front entry / exit door 14 in a closed position.

[0043] As shown in Figures 2, 4, and 5, the locking mechanism 16 has a snatch lock portion 16A, a striker 16B, and a door lever 16C. The striker 16B corresponds to the "first engagement portion." The snatch lock portion 16A corresponds to the "second engagement portion." The door lever 16C corresponds to the "single operating tool."

[0044] An opening 14h is formed in the rear of the door body 14A of each of the left and right front boarding / exiting doors 14. The opening 14h penetrates from the inner surface 14D to the outer surface 14E. The opening 14h is located in the central portion of the door body 14A in the vertical direction. The opening 14h is also located closer to the free end than the central portion between the swing base end and the swing free end. A single door lever 16C is provided in the opening 14h. A passenger can operate the door lever 16C from both inside and outside the driver's section 3.

[0045] The door lever 16C is disposed at a position lower than the seating surfaces of the seats 10A and 11A. This reduces the possibility that the hand of a passenger inside the driver's section 3 will accidentally touch the door lever 16C, compared to a configuration in which the door lever 16C is disposed at a position higher than the seating surfaces of the seats 10A and 11A.

[0046] Furthermore, an inclined portion 14i is formed in a portion of the inner surface portion 14D adjacent to the upper side of the opening 14h. The inclined portion 14i is inclined so that the upper portion is located laterally inward of the aircraft body when viewed in the longitudinal direction of the aircraft. As shown in FIG. 3, an extension line E of the inclined portion 14i overlaps with the upper left portion of the backrest portion 10B. Furthermore, the door lever 16C is located laterally inward of the aircraft body with respect to the extension line E of the inclined portion 14i. Furthermore, although not shown because the configuration is the same as that shown in FIG. 3, the extension line E of the inclined portion 14i also overlaps with the upper right portion of the backrest portion 11B of the auxiliary seat 11 in the front entry / exit door 14 on the right side of the aircraft. Furthermore, the door lever 16C of the front entry / exit door 14 on the right side of the aircraft body is located laterally inward of the aircraft body with respect to the extension line E of the inclined portion 14i of the front entry / exit door 14 on the right side of the aircraft body. Therefore, compared to a configuration in which the inclined portion 14i is not formed, it becomes easier for passengers to clearly see the door lever 16C from an upper viewpoint and to operate the door lever 16C from the driver's seat 10.

[0047] The snatch lock portion 16A is fixed to the planar portion 22 at the bottom of the frame body 14F by bolting. The door lever 16C is supported by the snatch lock portion 16A. The striker 16B is attached to the seat frame 17.

[0048] When a passenger closes the front boarding / deboarding door 14, the snatch lock portion 16A is hooked onto the striker 16B, as shown in Figures 4 and 5. When the front boarding / deboarding door 14 is closed, the snatch lock portion 16A and the striker 16B are engaged with each other, and the front boarding / deboarding door 14 is held in the closed position.

[0049] When the passenger swings the door lever 16C upward, the snatch lock 16A is released from the striker 16B, and the snatch lock 16A is disengaged from the striker 16B. In this state, when the passenger moves the door body 14A outward to the side of the aircraft, the door body 14A opens.

[0050] In this way, the door lever 16C is configured so that the snatch lock portion 16A and the striker 16B can be switched between an engaged state and a disengaged state by operating the snatch lock portion 16A.

[0051] When the utility vehicle turns, centrifugal force is applied laterally to the vehicle body, and a force acts laterally on the upper part of the door body 14A from the shoulders of the passenger in the auxiliary seat 11 or from cargo placed on the seat portion 11A of the auxiliary seat 11. The snatch lock portion 16A and the striker 16B engage at the center of the top and bottom of the rear portion of the door body 14A. Therefore, when a force acts laterally on the upper part of the door body 14A, a twisting force acts on the upper part of the door body 14A, twisting it outward laterally, across the engagement point between the snatch lock portion 16A and the striker 16B, and a twisting force acts on the lower part of the door body 14A, twisting it inward laterally, across the engagement point.

[0052] To cope with this twisting force, in this embodiment, a rubber (elastic) contact portion 23 is attached to the portion of the planar portion 22 of the frame body 14F below the snatch lock portion 16A. The contact portion 23 may be made of, for example, silicone.

[0053] The portion of the planar portion 22 of the frame body 14F to which the abutting portion 23 is attached faces the planar portion 24 of the seat frame 17. Therefore, when the passenger closes the front getting-in / out door 14, the abutting portion 23 abuts against the planar portion 24 of the seat frame 17. Because the abutting portion 23 is made of rubber, the impact between the planar portion 22 of the frame body 14F and the planar portion 24 of the seat frame 17 is mitigated when the passenger closes the front getting-in / out door 14.

[0054] By the abutment between the abutting portion 23 and the planar portion 24, even if a force acts laterally on the upper part of the door body 14A, the force acting laterally inward on the lower part of the door body 14A is received by the abutting portion 23 and the planar portion 24. This suppresses twisting of the lower part of the door body 14A.

[0055] In addition, the rigidity of the rear portion of the door body 14A is increased by the frame body 14F. Therefore, when a force acting laterally inward on the lower portion of the door body 14A is received by the abutment portion 23 and the planar portion 24, twisting of the upper portion of the door body 14A laterally outward on the aircraft body is suppressed.

[0056] [Another embodiment] The present invention is not limited to the configurations exemplified in the above-described embodiments, and other representative embodiments of the present invention will be exemplified below.

[0057] (1) The rear getting-in / out door 15 may have the same configuration as the front getting-in / out door 14. Specifically, the rear getting-in / out door 15 may be configured to be provided with a shoulder guard portion 14B that extends up and down to a position corresponding to the upper part of the backrest portion 12B. Furthermore, the shoulder guard portion 14B of the rear getting-in / out door 15 may be configured to be provided with a frame body 14F for reinforcing the rear getting-in / out door 15, similar to the frame body 14F of the front getting-in / out door 14.

[0058] (2) The shoulder guard portion 14B does not have to be integral with the door body 14A. The shoulder guard portion 14B may be separate from the door body 14A.

[0059] (3) The door lever 16C may be provided on both the inner surface 14D and the outer surface 14E of the front getting-into / outside door 14.

[0060] (4) The frame body 14F may be attached to the outer surface portion 14E of the front getting-into / out door 14.

[0061] (5) In addition to or instead of the seat frame 17, the planar portion 22 may be configured to abut against the lower portion of the center pillar 13A.

[0062] (6) The multipurpose vehicle described above has rear seats 12 and rear entry / exit doors 15, but may have a configuration that does not have rear seats 12 and rear entry / exit doors 15.

[0063] The configurations disclosed in the above-described embodiments (including other embodiments, the same applies hereinafter) can be applied in combination with the configurations disclosed in other embodiments, unless a contradiction arises. Furthermore, the embodiments disclosed in this specification are merely examples, and the present invention is not limited to these, and can be modified as appropriate within the scope of the purpose of the present invention.
