[0035] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0036] Reference will be made below Figures 1-7 to describe the rear protection structure 20 according to the first aspect embodiment of the present utility model.

[0037] As Figures 1-5 shown, the rear protection structure 20 according to the first aspect embodiment of the present utility model is used for the vehicle 100. The rear protection structure 20 includes: a protective member 21 and a driving mechanism 22.

[0038] The protective member 21 extends horizontally and is movable between a protection position and a stepping position. In the protection position, the protective member 21 is adapted to protect the rear part of the vehicle body. In the stepping position, the protective member 21 is horizontally arranged for stepping; the driving mechanism 22 is connected to the protective member 21 and is used to drive the protective member 21 to move between the protection position and the stepping position.

[0039] Specifically, the rear protection structure 20 is fixed to the rear position of the vehicle 100 by bolts. Further, the rear protection structure 20 can be fixed to the cross beam at the rear of the vehicle 100 by bolts. The protection member 21 of the rear protection structure 20 extends in the width direction of the vehicle 100. Further, the width of the protection member 21 can be the same as the width of the vehicle 100 in the width direction. When the protection member 21 is in the protection position, the protection member 21 is arranged perpendicular to the ground. On the one hand, the protection member 21 effectively protects the rear part of the vehicle 100 within the width range of the protection member 21 in the width direction of the vehicle 100. On the other hand, the protection member 21 can effectively prevent the occurrence of an intrusion collision. When the protection member 21 is in the stepping position, the protection member 21 is arranged parallel to the ground for the user to step on when getting on and off the cargo box 10.

[0040] The driving mechanism 22 is arranged in front of the protection member 21 in the length direction of the vehicle 100. Further, the driving mechanism 22 can be arranged in the bottom space of the cargo box 10. The driving mechanism 22 includes a driving motor 221 and a motor wire harness 222. Further, one end of the motor wire harness 222 is connected to the driving motor 221, and the other end of the motor wire harness 222 is connected to a power source. The control switch of the rear protection structure 20 of the vehicle 100 can control the driving motor 221. Further, the control switch can be arranged on the central control console of the vehicle 100 or on the protection member 21 of the rear protection device. The driving motor 221 can drive the protection member 21 to move between the protection position and the stepping position. In addition, the height of the rear protection structure 20 from the ground can meet the relevant current automobile design specifications.

[0041] It should be noted that for the rear protection device of the vehicle 100 with a pedal function in the prior art, when opening its pedal function, it often requires manual operation by the user, which is very inconvenient, not easy to store, occupies space and affects the aesthetics. In addition, when installing the rear protection structure 20 of the vehicle 100, there is a problem that the rotation is stuck due to different axles caused by assembly misalignment, which affects the work efficiency and the user experience.

[0042] In this embodiment, the user can make the protective member 21 of the rear protection structure 20 move between the stepping position and the protection position by turning on or off the control switch of the rear protection structure 20 of the vehicle 100. When the user turns on the control switch of the rear protection structure 20, the protective member 21 moves from the protection position to the stepping position, and the rear protection structure 20 changes from the rear protection state to the pedal state. The user can conveniently load and unload the cargo box 10 by stepping on the protective member 21. At the same time, the rear protection structure 20 is firmly installed at the rear position of the vehicle 100 by bolts, and the protective member 21 itself also has sufficient structural strength. The user can load or unload the goods in the cargo box 10 by stepping on the protective member 21, effectively improving the work efficiency of the user. When the user turns off the control switch of the rear protection structure 20, the protective member 21 moves from the stepping position to the protection position, and the rear protection structure 20 changes from the pedal state to the protection state. When the vehicle 100 is driving on the road, the protective member 21 effectively protects the rear part of the vehicle 100 within the width range of the protective member 21 in the width direction of the vehicle 100. On the one hand, the protective member 21 can protect the rear part of the vehicle 100 itself. On the other hand, the protective member 21 can effectively prevent the rear-end vehicle 100 from drilling into and colliding, fully ensuring the safety of the vehicle 100 during driving and minimizing the losses caused by vehicle 100 collision accidents to the greatest extent.

[0043] According to the rear protection structure 20 of the embodiment of the present utility model, by arranging the protective member 21 and the driving mechanism 22 in the rear protection structure 20, it can not only effectively protect the rear part of the vehicle 100, effectively prevent the occurrence of drilling collisions, and improve safety, but also be used as a pedal to improve the work efficiency of the user. Thus, the rear protection structure 20 has the dual functions of vehicle 100 protection and upper and lower pedals, and can effectively reduce the number of components. At the same time, the driving mechanism 22 can drive the protective member 21 to move between the protection position and the stepping position, effectively improving the user experience.

[0044] In an embodiment of the present utility model, as Figure 3 shown, the rear protection structure 20 further includes: a flipping mechanism 23, and the flipping mechanism 23 is connected between the driving mechanism 22 and the protective member 21, and the driving mechanism 22 drives the protective member 21 to rotate through the flipping mechanism 23.

[0045] For example, the flipping mechanism 23 of the rear protection structure 20 is arranged at the front position of the protective member 21 in the longitudinal direction of the vehicle 100, and one end of the flipping mechanism 23 is fixedly connected to one end of the protective member 21. The flipping mechanism 23 of the rear protection structure 20 is arranged at the rear position of the driving mechanism 22 in the longitudinal direction of the vehicle 100, and can drive the flipping mechanism 23 to move, thereby controlling the protective member 21 to rotate between the stepping position and the protection position.

[0046] Turn on the control switch of the rear protection structure 20 of the vehicle 100, and the driving mechanism 22 drives the flipping mechanism 23 to move, thereby controlling the protection member 21 to rotate from a state perpendicular to the ground to a state parallel to the ground. Turn off the control switch of the rear protection structure 20 of the vehicle 100, and the driving mechanism 22 drives the flipping mechanism 23 to move, thereby controlling the protection member 21 to rotate from a state parallel to the ground to a state perpendicular to the ground.

[0047] Thus, by providing the flipping mechanism 23 in the rear protection structure 20, the rotation of the protection member 21 between the protection position and the stepping position can be conveniently realized, further improving work efficiency. At the same time, the provision of the flipping mechanism 23 can effectively enhance the practicality of the rear protection structure 20 and the convenience of storing the protection member 21.

[0048] In an embodiment of the present invention, as Figure 6 shown, the flipping mechanism 23 includes: a fixed seat 231, a rotating shaft 232, and a connecting rod assembly 233. The fixed seat 231 is adapted to be fixed to the vehicle body; the rotating shaft 232 is rotatably provided on the fixed seat 231, and the driving mechanism 22 is connected to the rotating shaft 232 for driving the rotating shaft 232 to rotate; the connecting rod assembly 233 is provided on the fixed seat 231 and connected between the rotating shaft 232 and the protection member 21, and the rotating shaft 232 drives the protection member 21 to rotate through the connecting rod assembly 233.

[0049] Specifically, the fixed seat 231 is arranged in the lower rear space of the cargo box 10 of the vehicle 100. Further, a top plate 2311 is provided at the top position of the fixed seat 231. The shape of the top plate 2311 can be rectangular, and the four right angles of the rectangle are rounded and provided with four bolt holes for bolt connection. The fixed seat 231 can be fixed to the cross beam behind the vehicle 100 by bolts. In addition, connection holes are provided at both ends of the fixed seat 231 in the longitudinal direction of the vehicle 100. The rotating shaft 232 is rotatably provided in the connection hole at the front end of the fixed seat 231 in the longitudinal direction of the vehicle 100, and the driving mechanism 22 is connected to the rotating shaft 232 for driving the rotating shaft 232 to rotate.

[0050] The connecting rod assembly 233 is arranged below the fixed seat 231, between the rotating shaft 232 and the protection member 21. One end of the connecting rod assembly 233 is connected to the rotating shaft 232, and the other end is connected to the fixed frame and the protection member 21.

[0051] Turn on or off the control switch of the rear protection structure 20 of the vehicle 100, and the driving mechanism 22 drives the rotating shaft 232 to rotate in the connection hole at the front end of the fixed seat 231 in the longitudinal direction of the vehicle 100, and at the same time drives the movement of the connecting rod assembly 233 connected thereto, thereby driving the rotation of the protection member 21 connected to the connecting rod assembly 233, and further realizing the switching of the rear protection structure 20 of the vehicle 100 between the rear protection state and the pedal state.

[0052] Thus, by providing a fixed seat 231 in the flipping mechanism 23, the rotating shaft 232 and the link assembly 233 in the flipping mechanism 23 can be stably connected to the fixed seat 231. At the same time, the top plate 2311 of the fixed seat 231 can be bolted to the lower rear part of the cargo box 10 of the vehicle 100, so that the rear protection structure 20 of the vehicle 100 can be firmly installed on the vehicle 100. By providing the rotating shaft 232 and the link assembly 233 in the flipping mechanism 23, the power provided by the driving mechanism 22 can be transmitted to the link assembly 233 to drive the movement of the link assembly 233, and then drive the rotation of the protection member 21 connected to the link assembly 233, thus facilitating the operation of the user.

[0053] In an embodiment of the present utility model, as Figure 6 shown, the link assembly 233 includes: a first rotating member 2331, a second rotating member 2332, and a connecting rod 2333. One end of the first rotating member 2331 is fixed to the rotating shaft 232; the second rotating member 2332 is rotatably provided on the fixed seat 231, and the protection member 21 is fixedly connected to the second rotating member 2332; the connecting rod 2333 is rotatably connected to the first rotating member 2331 and the second rotating member 2332 respectively.

[0054] For example, the upper end of the first rotating member 2331 is connected to the rotating shaft 232. Further, the connection between the upper end of the first rotating member 2331 and the rotating shaft 232 can adopt a key connection. The first rotating member 2331 can rotate together with the rotating shaft 232. The lower end of the first rotating member 2331 is hinged to the front end of the connecting rod 2333. The middle part of the second rotating member 2332 is rotatably provided in the connection hole at the rear end of the fixed seat 231 in the longitudinal direction of the vehicle 100. The rear end of the second rotating member 2332 is fixedly connected to the protection member 21, and the front end of the second rotating member 2332 is hinged to the rear end of the connecting rod 2333.

[0055] When the rear protection structure 20 is converted from the rear protection state to the pedal state, the driving mechanism 22 drives the rotating shaft 232 to rotate clockwise. The rotating shaft 232 drives the first rotating member 2331 to rotate clockwise. The first rotating member 2331 drives the connecting rod 2333 to move leftward and downward. The connecting rod 2333 drives the second rotating member 2332 to rotate counterclockwise about a fixed axis. The second rotating member 2332 drives the protection member 21 to rotate counterclockwise. Finally, the protection member 21 rotates from the protection position to the stepping position.

[0056] When the rear protection structure 20 is converted from the pedal state to the rear protection state, the driving mechanism 22 drives the rotating shaft 232 to rotate counterclockwise. The rotating shaft 232 drives the first rotating member 2331 to rotate counterclockwise about a fixed axis. The first rotating member 2331 drives the connecting rod 2333 to move backward and upward. The connecting rod 2333 drives the second rotating member 2332 to rotate clockwise about a fixed axis. The second rotating member 2332 drives the protection member 21 to rotate clockwise. Finally, the protection member 21 rotates from the stepping position to the protection position.

[0057] In this embodiment, by providing the first rotating member 2331, the second rotating member 2332, and the connecting rod 2333 in the link assembly 233, the driving force transmitted by the driving mechanism 22 to the rotating shaft 232 can be effectively transmitted to the protection member 21. At the same time, through the connection methods of key connection and hinge connection, the efficiency of driving force transmission is further ensured. In addition, due to the structure of the link assembly 233 itself, it occupies a small space and has a light structure weight, effectively improving the durability of use.

[0058] In an embodiment of the present utility model, as Figure 3 shown, the number of the flipping mechanisms 23 is multiple, and the multiple flipping mechanisms 23 are arranged at intervals along the length direction of the protection member 21.

[0059] For example, the number of the flipping mechanisms 23 can be two, and they are arranged symmetrically along the length direction of the protection member 21. Further, one of the flipping mechanisms 23 is close to the driving mechanism 22, and the other flipping mechanism 23 is far from the driving mechanism 22. The fixed seat 231 in each driving mechanism 22 is firmly installed at the lower rear part of the vehicle 100 through bolts.

[0060] When the rear protection structure 20 is in the rear protection state or the pedal state, the fixed seats 231 in the multiple flipping mechanisms 23 can provide multiple stable force application points for the protection member 21, realizing the common force bearing of the multiple fixed seats 231.

[0061] Thus, by providing multiple flipping mechanisms 23 in the rear protection structure 20, the fixed seats 231 in the multiple flipping mechanisms 23 can jointly bear the collision force or the stepping force transmitted by the protection member 21, effectively increasing the number of force application points of the rear protection structure 20, and further improving the safety and reliability of the rear protection structure 20 when a collision occurs or when the pedal is used.

[0062] In an embodiment of the present utility model, as Figure 3 and Figure 5 shown, the driving mechanism 22 is connected to the rotating shaft 232 of one of the flipping mechanisms 23. The rear protection structure 20 further includes: a transmission mechanism 24, and the transmission mechanism 24 is connected between the rotating shafts 232 of two adjacent flipping mechanisms 23.

[0063] For example, two flipping mechanisms 23 are provided in the rear protection structure 20. The driving mechanism 22 is connected to the left end of the rotating shaft 232 of the flipping mechanism 23 close to it. The right end of the rotating shaft 232 of the flipping mechanism 23 close to the driving mechanism 22 is connected to the left end of the transmission mechanism 24. The right end of the transmission mechanism 24 is connected to the left end of the rotating shaft 232 of the flipping mechanism 23 far from the driving mechanism 22.

[0064] When the driving mechanism 22 works, the driving mechanism 22 drives the rotation of the rotating shaft 232 of the flipping mechanism 23 connected to it. The rotating shaft 232 transfers a part of the driving force to the transmission mechanism 24 through rotation. Then, the transmission mechanism 24 transfers this part of the driving force to the rotating shaft 232 of another flipping mechanism 23. The rotating shafts 232 of each driving mechanism 22 transfer the driving force effectively and evenly to the protection part 21 through rotation, so that the protection part 21 is stressed at multiple points and evenly stressed when rotating.

[0065] Therefore, by connecting the rotating shaft 232 of the driving mechanism 22 and the flipping mechanism 23 and arranging the transmission mechanism 24 in the rear protection structure 20, the efficiency and reliability of the driving force during transmission are ensured, so as to realize the effective and even transfer of the driving force from the driving mechanism 22 to the protection part 21, and then ensure that the protection part 21 can rotate evenly.

[0066] In an embodiment of the present invention, as Figure 7 shown, the transmission mechanism 24 includes: a transmission shaft 241 and a connecting member 242. The transmission shaft 241 extends along the length direction of the protection part 21; the connecting member 242 includes: a first connecting portion 2421 and a second connecting portion 2422. The first connecting portion 2421 is connected to the transmission shaft 241, and the second connecting portion 2422 is connected to the rotating shaft 232. The first connecting portion 2421 and the second connecting portion 2422 are flexibly connected.

[0067] Specifically, each transmission mechanism 24 includes one transmission shaft 241 and two connecting members 242. Each connecting member 242 includes a first connecting portion 2421, a second connecting portion 2422 and a flexible connecting component. Along the length direction of the protection part 21, the components of the transmission mechanism 24 are in turn the second connecting portion 2422, the flexible connecting component, the first connecting portion 2421, the transmission shaft 241, the first connecting portion 2421, the flexible connecting component and the second connecting portion 2422. One end of the second connecting portion 2422 is fixedly connected to one end of the rotating shaft 232 of the flipping mechanism 23. The other end of the second connecting portion 2422 is connected to one end of the first connecting portion 2421 through the flexible connecting component. Both ends of the transmission shaft 241 are fixedly connected to the first connecting portion 2421.

[0068] It should be noted that a flexible connection is a connection method that allows axial expansion and contraction, folding, and a certain amount of displacement perpendicular to the axis at the connection part. Flexible connection components can adopt elastic joints such as rubber joints and bellows, pipe fittings with special structures, and flexible fillers, etc.

[0069] When the driving mechanism 22 drives the rotation of the rotating shaft 232 of the flipping mechanism 23, the rotating shaft 232 drives the rotation of the second connecting part 2422. The second connecting part 2422 drives the first connecting part 2421 to rotate through the flexible connection component. The first connecting part 2421 drives the transmission shaft 241 to rotate. The transmission shaft 241 drives another first connecting part 2421 to rotate. Another first connecting part 2421 drives another second connecting part 2422 to rotate through another flexible connection component. Another second connecting part 2422 drives the rotation of the rotating shaft 232 of another flipping mechanism 23, finally realizing the effective transmission of the driving force in the transmission mechanism 24.

[0070] In this embodiment, by arranging the transmission shaft 241 and the connecting piece 242 in the transmission mechanism 24, the driving force transmitted from the driving mechanism 22 to the rotating shaft 232 of the flipping mechanism 23 can be effectively transmitted to the rotating shaft 232 of another adjacent flipping mechanism 23, thus ensuring the reliability of the driving force transmission in the rear protection structure 20. At the same time, by arranging the flexible connection component between the first connecting part 2421 and the second connecting part 2422, the variable-angle driving force transmission when the transmission shaft 241 changes its line can be realized, further ensuring the reliability of the driving force transmission in the rear protection structure 20.

[0071] In an embodiment of the present utility model, as Figure 7 shown, the connecting piece 242 is a universal joint.

[0072] Specifically, the universal joint is composed of a first connecting part 2421, a second connecting part 2422, a cross shaft 2423, and a bearing outer ring 2424. The bearing outer rings 2424 are respectively sleeved on the upper end, lower end, left end, and right end of the cross shaft 2423. The first connecting part 2421 is connected to the upper and lower ends of the cross shaft 2423, and the second connecting part 2422 is connected to the left and right ends of the cross shaft 2423. When the universal joint works in cooperation with the transmission shaft 241, the variable-angle driving force transmission when the transmission shaft 241 changes its line can be realized.

[0073] In this embodiment, by arranging the universal joint in the transmission mechanism 24, it can solve the problem of the running jam of the protective part 21 caused by the misalignment of the axes due to assembly misalignment, and improve the assemblability and platform versatility of the rear protection structure 20.

[0074] In an embodiment of the present utility model, as Figure 3 and Figure 5As shown, the rear protection structure 20 further includes a speed reduction mechanism 25. The driving mechanism 22 is a driving motor 221, and the driving motor 221 is connected to the flipping mechanism 23 through the speed reduction mechanism 25.

[0075] For example, the speed reduction mechanism 25 adopts a speed reduction gear mechanism. Specifically, the speed reduction gear mechanism is arranged between the driving mechanism 22 and the flipping mechanism 23, and the speed reduction gear mechanism is fixed to the side of the flipping mechanism 23 close to the driving mechanism 22 by bolts. The driving mechanism 22 includes a driving motor 221 and a motor wiring harness 222. Further, one end of the motor wiring harness 222 is connected to the driving motor 221, and the other end of the motor wiring harness 222 is connected to a power source. When the driving motor 221 operates, the driving force generated by the driving motor 221 can be transmitted to the rotating shaft 232 of the flipping mechanism 23 connected to the speed reduction gear mechanism through the speed reduction gear mechanism.

[0076] In this embodiment, by arranging the speed reduction mechanism 25 in the rear protection structure 20, the output speed of the driving motor 221 can be reduced and the torque can be increased. At the same time, the effect of increasing the transmission power can be achieved, thereby ensuring that the driving motor 221 can provide sufficient driving force to drive the protection member 21 to rotate smoothly.

[0077] In an embodiment of the present utility model, as Figures 1-4 shown, the protection member 21 includes a protection main body 211 and a panel 212. The protection main body 211 defines a cavity 2111 that is open on one side in the thickness direction. Reinforcing ribs 2112 are provided in the cavity 2111, and the panel 212 covers the open side of the protection main body 211. Among them, when the protection member 21 is in the protection position, the panel 212 is located at the rear side of the protection main body 211, and when the protection member 21 is in the stepping position, the panel 212 is located at the upper side of the protection main body 211.

[0078] Specifically, the protection main body 211 has a cavity 2111 that is open on one side, and the reinforcing ribs 2112 are arranged in the cavity 2111. The panel 212 covers the open side of the protection main body 211 through screws 215. Further, the number of the reinforcing ribs 2112 can be multiple, and they are evenly spaced in the cavity 2111 of the protection main body 211. The reinforcing ribs 2112 and the protection main body 211 jointly form the metal skeleton of the protection member 21. Further, the panel 212 can be made of a plastic material with sufficient strength. The protection surface or the stepping surface of the panel 212 is provided with an anti-slip structure, and the panel 212 has sufficient width. Further, a first connection clip 213 and a second connection clip 214 are arranged in the protection member 21, and both are used for pre-installation and can play a role in preliminary positioning. Among them, the first connection clip 213 is used for the pre-installation of the protection main body 211 and the panel 212, and the second connection clip 214 is used for the pre-installation of the protection member 21 and the second rotating member 2332.

[0079] When the protective member 21 of the rear protection structure 20 is in the stepping position, the protective member 21 can be used as a pedal. Users can conveniently get on and off the cargo box 10 by stepping on the panel 212 of the protective member 21. At the same time, users can also load or unload the goods in the cargo box 10 by stepping on the panel 212 of the protective member 21. When the protective member 21 of the rear protection structure 20 is in the rear protection position, the protective member 21 can be used as the rear protection device of the vehicle 100. When the vehicle 100 is traveling on the road, the protective member 21 effectively protects the rear part of the vehicle 100 within the width range of the protective member 21 in the width direction of the vehicle 100. On the one hand, the protective member 21 can protect the rear part of the vehicle 100 itself. On the other hand, the protective member 21 can effectively prevent the rear-end vehicle 100 from drilling into a collision.

[0080] Thus, by providing the protective member 21 in the rear protection structure 20, it is extremely convenient for users to get on and off the cargo box 10 and carry goods, effectively improving the efficiency of users in carrying goods. In addition, the protective member 21 has a simple appearance, is convenient to store, and has a beautiful shape. At the same time, the protective member 21 can effectively protect the rear part of the vehicle 100, effectively prevent the occurrence of drilling collisions, and has high safety.

[0081] As Figure 1 and Figure 2 shown, the vehicle 100 according to the second aspect embodiment of the present invention includes: a cargo box 10 and a rear protection structure 20 according to the first aspect embodiment of the present invention above. The rear protection structure 20 is provided below the rear side of the cargo box 10. For example, the top plate 2311 of the fixed seat 231 is connected to the cross beam below the rear side of the vehicle 100 using bolts, thereby fixing the rear protection structure 20 to the vehicle 100.

[0082] According to the vehicle 100 of the embodiment of the present utility model, by providing the rear protection structure 20 of the first aspect embodiment, it can not only effectively protect the rear part of the vehicle 100, effectively prevent the occurrence of penetration collision, and improve safety, but also be used as a pedal to improve the work efficiency of users. Thus, the rear protection structure 20 has the dual functions of protecting the vehicle 100 and serving as an up-and-down pedal, and can effectively reduce the number of components. At the same time, the driving mechanism 22 can drive the protection member 21 to move between the protection position and the stepping position, effectively improving the user experience.
