Description

Technical Field

[0001] This application relates to the field of vehicle structure technology, and more particularly to an all-terrain vehicle. Background Technology

[0002] All-terrain vehicles (ATVs), also known as "all-terrain four-wheel off-road vehicles," are simple, practical, and have excellent off-road performance. ATVs feature wide tires, which not only increase the contact area with the ground to generate greater friction but also reduce the pressure exerted on the ground, making them easy to traverse in harsh terrain environments such as beaches, riverbeds, forest trails, streams, and deserts.

[0003] Because all-terrain vehicles experience significant body sway when driving in harsh terrain, regulations mandate the installation of occupant protection bars in doorless all-terrain vehicles to meet occupant safety requirements. However, these bars need to be quite large to ensure effectiveness, and existing products are mostly fixed or horizontally rotating. Fixed bars severely restrict passenger access, while horizontally rotating bars require separate brackets and locking hooks on the top bar to limit rotation and ensure a fixed angle when locked. Therefore, these brackets and hooks occupy lateral space within the vehicle, impacting passenger comfort. Summary of the Invention

[0004] In order to improve the restriction of passengers getting on and off the vehicle by the guardrail and enhance the passenger experience, this application provides an all-terrain vehicle.

[0005] An embodiment of this application provides an all-terrain vehicle, including a frame, a roof bar, and a guard bar. The roof bar is mounted on the frame; the guard bar is disposed on the roof bar, and the surface where the guard bar and the roof bar are located is a protective plane for enclosing the occupants of the all-terrain vehicle; the guard bar has a hinged end and a movable locking end, and the all-terrain vehicle also includes a locking device. When the movable locking end is fixedly connected to the locking device to form a stable state for the guard bar, the guard bar is in a locked state; when the movable locking end is separated from the locking device, the guard bar is in an open state.

[0006] In the above embodiments, during the process of passengers getting on and off the vehicle, the movable locking end of the protective bar can rotate around the hinge end within the protective plane. At this time, the lock separates from the movable locking end, and the protective bar is in the open state. By changing the position occupied by the protective bar within the protective plane, the restriction of the protective bar on the door position of the all-terrain vehicle is reduced, thereby facilitating passenger entry and exit. After the passengers have boarded the vehicle, the movable locking end of the protective bar is returned to the locked state. At this time, the movable locking end is fixedly connected to the lock, and the position of the movable locking end and the hinge end is fixed, thereby fixing the position of the entire protective bar and acting as a barrier for the passengers, improving the restriction of the protective bar on passengers getting on and off the vehicle. At the same time, the movable locking end of the protective bar rotates around the hinge end within the protective plane without occupying the space of the passenger compartment, improving the riding experience inside the vehicle.

[0007] In at least one embodiment, the top bar is provided with a hinge shaft and a locking block on its side, and the hinge end of the protective rod is hinged to the hinge shaft; the movable locking end of the protective rod is fixedly provided with a locking hook, and the locking block and the locking hook are detachably connected.

[0008] In the above embodiment, a locking hook is fixedly installed at the movable locking end of the protective rod, and is detachably connected to a locking block provided on the side of the top bar. Since the positions of the hinge shaft and the locking block are fixed, by fixing the locking hook and the locking block to each other, the positions of the movable locking end and the hinge end are fixed, thereby fixing the position of the entire protective rod. By hinged the hinge end of the protective rod to the hinge shaft, the protective rod is positioned on the protective plane during rotation, thus eliminating the need to adjust the position of the protective rod and facilitating direct engagement between the locking hook and the locking block.

[0009] In at least one embodiment, the protective rod is formed by hinged protective section and fixed protective section, wherein the hinged end is located at the end of the hinged protective section away from the fixed protective section, and the movable fixed end is located at the end of the fixed protective section away from the hinged protective section.

[0010] The top bar is provided with a hinge shaft and a locking block on its side, and the hinge end of the hinge protection section is hinged to the hinge shaft; the movable locking end of the locking protection section is fixedly provided with a locking hook, and the locking block and the locking hook are detachably connected.

[0011] In the above embodiment, the movable locking end of the fixed locking section is fixedly equipped with a locking hook, which is detachably connected to a locking block provided on the side of the top bar. Since the guard bar is composed of a hinged guard bar and a fixed locking guard bar hinged together, by fixing the locking hook and the locking block to each other, the hinge point, hinge axis, and locking block between the hinged guard bar and the fixed locking guard bar form a stable triangular support, thereby fixing the position of the entire guard bar. Furthermore, the hinged connection between the hinged guard bar and the fixed locking guard bar allows the guard bar to occupy less space within the protective plane, thus requiring less rotation of the guard bar to allow for easier access to and from the vehicle.

[0012] In at least one embodiment, the lock block includes a mounting base, a lock plate, a first torsion spring, a limiting plate, and a second torsion spring. The mounting base has a notch for accommodating the lock hook. The lock plate is rotatably connected to the mounting base, and both ends of the lock plate are respectively provided with a fork and a slot. The fork is used to engage with the notch to lock the lock hook. The first torsion spring has a spring force to push the lock plate from the locking position to the unlocking position. The limiting plate is rotatably connected to the mounting base and is located on the side of the lock plate away from the lock hook. The limiting plate is used to abut against the slot to keep the lock plate in the locking position. The second torsion spring has a spring force to push the limiting plate from the unlocking position to the locking position.

[0013] In the above embodiments, when it is necessary to fix the lock hook and the lock block, the lock hook is pressed into the fork and the lock plate is pushed to rotate, so that the notch of the mounting base and the fork of the lock plate simultaneously engage the lock hook. At this time, the limiting plate abuts against the groove of the lock plate, preventing the lock plate from resetting, thereby locking the lock hook, and the locking process is stable. When it is necessary to unlock the lock hook and the lock block, the limiting plate is rotated against the elastic force of the second torsion spring, the limiting plate separates from the groove of the lock plate, the first torsion spring drives the lock plate to reset, thereby pushing out the lock hook, making unlocking convenient.

[0014] In at least one embodiment, the lock block further includes a handle, which is fixedly disposed on the end face of the limiting plate away from the lock plate.

[0015] In the above embodiments, by fixing a handle to the limiting plate, the locking plate has a longer lever arm during the process, which makes it easier to disengage the limiting plate from the slot of the locking plate. At the same time, the surface of the handle is smooth and uniform, which makes it easy to bear force and improves the ease of use of the locking block.

[0016] In at least one embodiment, the protective rod is composed of a first protective section and a second protective section, which are detachably connected by a locking assembly. Two hinge ends are provided: one hinge end is located on the end face of the first protective section away from the locking assembly, and the other hinge end is located on the end face of the second protective section away from the locking assembly. Two movable locking ends are provided: one movable locking end is located on the end face of the first protective section close to the locking assembly, and the other movable locking end is located on the end face of the second protective section close to the locking assembly. A hinge shaft and a hinge seat are provided on the side of the top bar. The rotation axis of the hinge seat is perpendicular to the protective plane. The hinge end of the first protective section is hinged to the hinge shaft, and the hinge end of the second protective section is hinged to the hinge seat. The movable locking end of the first protective section rotates around the hinge shaft, and the movable locking end of the second protective section rotates around the hinge seat.

[0017] In the above embodiment, a hinge shaft and a hinge seat are provided on the side of the top bar. The hinge ends of the first and second protective sections are respectively hinged to the hinge shaft and the hinge seat. Since the rotation axis of the hinge seat is perpendicular to the protective plane, the first and second protective sections are detachably connected by a locking assembly. The fixing point between the first and second protective sections, the hinge shaft, and the hinge seat form a stable triangular support, thereby fixing the position of the entire protective bar. Furthermore, the hinge ends of the first and second protective sections are respectively hinged to the hinge shaft and the hinge seat, which allows the protective bar to occupy less space within the protective plane, thus requiring less space for the protective bar to rotate and create space for getting on and off the vehicle.

[0018] In at least one embodiment, the locking assembly includes a snap-fit ​​sleeve and a snap-fit ​​connector. The snap-fit ​​sleeve is fixedly disposed at the movable locking end of the first protective section, and the snap-fit ​​connector is disposed at the movable locking end of the second protective section. The snap-fit ​​sleeve and the snap-fit ​​connector are snapped together.

[0019] In the above embodiments, by interlocking the snap-fit ​​sleeve on the first protective section with the snap-fit ​​connector on the second protective section, the first and second protective sections can be separated and locked more easily than by locking with a double-ended thread.

[0020] In at least one embodiment, the snap-fit ​​connector includes a snap-fit ​​base, a snap-fit ​​pin, an elastic element, and a locking cover. The snap-fit ​​base is fixedly connected to the movable locking end of the second protective section. The snap-fit ​​base is provided with a sliding groove. The snap-fit ​​pin is slidably disposed in the sliding groove. The elastic element is disposed in the sliding groove and has an elastic force that pushes the snap-fit ​​pin to move away from the center of the snap-fit ​​base. The locking cover is clamped to the snap-fit ​​base to limit the snap-fit ​​pin and the elastic element. The snap-fit ​​sleeve has a receiving cavity for accommodating the snap-fit ​​connector. The side wall of the snap-fit ​​sleeve is provided with a locking hole for engaging with the snap-fit ​​pin to form a snap-fit ​​engagement.

[0021] In the above embodiments, when it is necessary to lock the snap-fit ​​connector and the snap-fit ​​sleeve, the snap-fit ​​connector is aligned with the receiving cavity of the snap-fit ​​sleeve, and the snap-fit ​​pin is pushed towards the center of the snap-fit ​​seat, so that the snap-fit ​​pin slides in the groove and presses against the elastic element. Since the locking cover is clamped in the snap-fit ​​seat, the locking cover can limit the snap-fit ​​pin and the elastic element, improving the problem of the snap-fit ​​pin and the elastic element popping out. By pushing the snap-fit ​​connector into the receiving cavity of the snap-fit ​​sleeve, the elastic element pushes the snap-fit ​​pin into the locking hole, thereby completing the snap-fit ​​of the first protective section and the second protective section. When it is necessary to unlock the first protective section and the second protective section, the snap-fit ​​pin is pushed out of the locking hole to separate the snap-fit ​​connector and the snap-fit ​​sleeve.

[0022] In at least one embodiment, the slide grooves are provided in two lines and are located on the same straight line, and each slide groove is provided with the locking pin and the elastic element.

[0023] In the above embodiment, by setting two slides, and the two slides being located on the same straight line, it is convenient to press both locking pins towards the center of the locking seat simultaneously when pushing the locking pins. At the same time, the two locking pins are symmetrically arranged to ensure that the locking connector and the locking sleeve are subjected to uniform force, thereby improving the connection stability.

[0024] In at least one embodiment, the all-terrain vehicle has entrances and exits on both sides of its frame for occupants to enter or exit the all-terrain vehicle, and the guard bar is located at the entrance and exit positions of the all-terrain vehicle's frame.

[0025] In the above embodiments, the guard bar is installed at the entrance and exit positions of the all-terrain vehicle frame, thereby providing side protection for the occupants while driving the all-terrain vehicle and improving the driving safety of the all-terrain vehicle.

[0067] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0068] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0069] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have a component that is centrally located. When a component is considered to be "set" on another component, it can be directly set on the other component or may also have a component that is centrally located.

[0070] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items.

[0071] Please see Figure 1 This application provides an all-terrain vehicle 100. Because all-terrain vehicles experience significant body sway when driving in harsh terrain, regulations require that all-terrain vehicles without doors be equipped with occupant protection bars on the frame to meet occupant protection requirements. To address this, the all-terrain vehicle 100 includes a frame and a protective structure 200.

[0072] Please see Figure 1 and Figure 2The protective structure 200 includes a top bar 10 and a guard rod 20 mounted on the vehicle frame. The top bar 10 is fixedly connected to the frame of the all-terrain vehicle 100. The guard rod 20 is located on the side of the top bar 10. The guard rod 20 and the top bar 10 protect the vehicle frame at the door position, thus enclosing the occupants of the all-terrain vehicle and improving passenger safety. In one embodiment, the all-terrain vehicle 100 also includes a locking mechanism. The guard rod 20 has a hinged end 21 and a movable locking end 22. When occupants need to get in or out of the vehicle, the guard rod 20 is in an open state, at which time the locking mechanism is separated from the movable locking end. The open state means that the movable locking end 22 can rotate around the hinged end 21 within the protective plane. By changing the position of the guard rod 20 within the protective plane, the restriction of the guard rod 20 at the door position of the all-terrain vehicle 100 is reduced, thereby facilitating occupant entry and exit. After the occupants have boarded the vehicle, the guard rod 20 is in a locked state, at which time the movable locking end is fixedly connected to the locking mechanism. The locked state refers to the movable locking end being fixed to the top bar by a locking device, thereby fixing the position of the entire guard bar 20 and serving as a barrier for the occupants.

[0073] The following detailed explanation uses the relative positional relationship between the guard bar 20 and the top bar 10 as an example.

[0074] In one embodiment, please refer to Figure 2 and Figure 3 The protective rod 20 has a hinged end 21a and a movable locking end 22a at its two ends, respectively. In the locked state, the hinged end 21a is located above the movable locking end 22a. In another embodiment, the hinged end 21a is located below the movable locking end 22a. By changing the installation positions of the hinged end 21a and the movable locking end 22a on the side of the top bar 10, the protective rod 20 can be opened from another angle. In one embodiment, the locking element is a locking block 12. A hinge shaft 11 and a locking block 12 are fixedly installed on the side of the top bar 10, with the hinge shaft 11 located above the locking block 12. The hinged end 21a of the protective rod 20 is hinged to the outer circumferential surface of the hinge shaft 11 via a rotating sleeve 211, and a locking hook 221 is fixedly installed on the movable locking end 22a of the protective rod 20. Please refer to [link to relevant documentation]. Figure 4 The locking hook 221 can rotate around the hinge shaft 11, and the locking block 12 is located on the rotation path of the locking hook 221, so that the locking block 12 can lock the locking hook 221. At the same time, since the protective rod 20 is located on the protective plane during rotation, there is no need to adjust the position of the protective rod 20, which facilitates the direct docking of the locking hook 221 and the locking block 12.

[0075] In one embodiment, please refer to Figure 2 and Figure 5The locking block 12 includes a mounting base 121, a locking plate 122, and a limiting plate 123, both of which are rotatably connected to the mounting base 121. The mounting base 121 has a notch 1211 for accommodating the locking hook 221. The locking plate 122 has a fork 1221 and a slot 1222 at both ends, with the fork 1221 engaging with the notch 1211 to engage the outer periphery of the locking hook 221. A first torsion spring (not shown) is provided at the rotatable connection between the locking plate 122 and the mounting base 121, pushing the locking plate 122 to rotate from the engaging position to the unlocking position. The locking position of the locking plate 122 is defined as the position where the fork 1221 of the locking plate 122 engages with the notch 1211 of the mounting base 121 to lock the outer periphery of the locking hook 221, i.e., the position where the locking hook 221 can be locked; the unlocking position of the locking plate 122 is defined as the position where, after the locking plate 122 is rotated, the notch 1211 of the mounting base 121 engages with the fork 1221 of the locking plate 122 to create an opening for the locking hook 221 to disengage, i.e., the position where the locking hook 221 cannot be locked.

[0076] Please continue reading. Figure 2 and Figure 5 The limiting plate 123 abuts against the slot 1222 to keep the locking plate 122 always in the aforementioned engaging position. A second torsion spring (not shown in the figure) is provided at the rotational connection between the limiting plate 123 and the mounting base 121. The second torsion spring is used to push the limiting plate 123 to rotate, so that the limiting plate 123 rotates from the unlocking position to the engaging position. The engaging position of the limiting plate 123 is indicated by the position where the limiting plate 123 abuts against the slot 1222 of the locking plate 122 to keep the locking plate 122 always in the engaging position of the locking plate 122; the unlocking position of the limiting plate 123 is indicated by the position where, after the limiting plate 123 rotates a certain angle, the limiting plate 123 separates from the groove of the locking plate 122 and no longer forms a restriction.

[0077] Please see Figure 5When it is necessary to fix the locking hook 221 to the locking block 12, the locking hook 221 is pressed into the fork 1221, and the locking plate 122 is rotated against the elastic force of the first torsion spring. This causes the notch 1211 of the mounting base 121 and the fork 1221 of the locking plate 122 to simultaneously engage the locking hook 221. At this time, the limiting plate 123 abuts against the slot 1222 of the locking plate 122, preventing the locking plate 122 from resetting, thereby locking the locking hook 221 and ensuring a stable locking process. At this time, both the locking block 12 and the limiting block are in the engaging position. When it is necessary to unlock the locking hook 221 from the locking block 12, the limiting plate 123 is rotated against the elastic force of the second torsion spring, causing the limiting plate 123 to separate from the slot 1222 of the locking plate 122. The first torsion spring drives the locking plate 122 to reset, thereby pushing out the locking hook 221. In one embodiment, a handle 124 is fixedly provided on the end face of the limiting plate 123 away from the locking plate 122, so that the locking plate 122 has a longer lever arm during the process, thereby facilitating the disengagement of the limiting plate 123 from the slot 1222 of the locking plate 122.

[0078] In one embodiment, please refer to Figure 6 and Figure 7 The protective rod 20 consists of two hinged sections: a hinged protective section 23 and a locking protective section 24, with the hinged protective section 23 located above the locking protective section 24. In another embodiment, the hinged protective section 23 is located below the locking protective section 24. By swapping the installation positions of the hinged protective section 23 and the locking protective section 24 on the side of the top bar 10, the protective rod 20 can be opened from another angle. The hinge end 21b is located at the end of the hinged protective section 23 away from the locking protective section 24, and the movable locking end 22b is located at the end of the locking protective section 24 away from the hinged protective section 23. A hinge shaft 11 and a locking block 12 are fixedly installed on the side of the top bar 10, with the hinge shaft 11 located above the locking block 12. The hinge end 21b of the hinged protection section 23 is hinged to the outer circumferential surface of the hinge shaft 11 through the rotating sleeve 211. The movable locking end 22b of the locking protection section 24 is fixedly provided with a locking hook 221. The locking block 12 and the locking hook 221 are detachably connected.

[0079] Please see Figure 6 and Figure 7 The locking hook 221 can rotate around the hinge point of the hinged protective section 23 and the fixed protective section 24, while the hinged protective section 23 can rotate around the hinge axis 11. By fixing the locking hook 221 and the locking block 12 to each other, the hinge point between the hinged protective section 23 and the fixed protective section 24, the hinge axis 11, and the locking block 12 form a stable triangular support, thereby fixing the position of the entire protective rod 20. Furthermore, the hinged protective section 23 and the fixed protective section 24 are hinged together, so that the protective rod 20 occupies less space in the protective plane when it is unlocked, thus allowing the protective rod 20 to rotate with less space to make way for getting on and off the vehicle.

[0080] In one embodiment, please refer to Figure 8 and Figure 9 The protective rod 20 consists of two separate sections: a first protective section 25 and a second protective section 26. The locking element is a locking assembly 27, which detachably connects the first protective section 25 and the second protective section 26, with the first protective section 25 positioned above the second protective section 26. In another embodiment, the first protective section 25 is positioned below the second protective section 26.

[0081] Two hinge ends 21c are provided: one hinge end 21c is located on the end face of the first protective section 25 away from the fixed locking component 27, and the other hinge end 21c is located on the end face of the second protective section 26 away from the fixed locking component 27. Two movable fixed locking ends 22c are provided: one movable fixed locking end 22c is located on the end face of the first protective section 25 close to the fixed locking component 27, and the other movable fixed locking end 22c is located on the end face of the second protective section 26 close to the fixed locking component 27. A hinge shaft 11 and a hinge seat 13 are fixedly provided on the side of the top bar 10, with the hinge shaft 11 located above the hinge seat 13. The rotation axis of the hinge seat 13 is perpendicular to the protective plane. The hinge end 21c of the first protective section 25 is hinged to the outer circumferential surface of the hinge shaft 11 through a rotating sleeve 211, and the hinge end 21c of the second protective section 26 is hinged to the hinge seat 13 through a rotating pin.

[0082] Please see Figure 9 The hinge end 21c of the first protective section 25 and the second protective section 26 can rotate around the rotation centers of the hinge shaft 11 and the hinge seat 13, respectively, so that the protective rod 20 occupies less space in the protective plane when it is unlocked. The first protective section 25 and the second protective section 26 are detachably connected by the locking assembly 27. The fixing point between the first protective section 25 and the second protective section 26, the hinge shaft 11, and the hinge seat 13 form a stable triangular support, thereby fixing the position of the entire protective rod 20.

[0083] Please refer to Figure 9 and Figure 10 The locking assembly 27 includes a snap-fit ​​sleeve 271 and a snap-fit ​​connector 272. The snap-fit ​​sleeve 271 has a receiving cavity for accommodating the snap-fit ​​connector 272, and the snap-fit ​​sleeve 271 can snap into the snap-fit ​​connector 272. The snap-fit ​​sleeve 271 is fixedly disposed at the movable locking end 22c of the first protective section 25, and the snap-fit ​​connector 272 is disposed at the movable locking end 22c of the second protective section 26, so as to facilitate the separation and locking of the first protective section 25 and the second protective section 26.

[0084] In one embodiment, the side wall of the snap-fit ​​sleeve 271 is provided with a locking hole 2711, and the snap-fit ​​connector 272 includes a snap-fit ​​base 2721, a snap-fit ​​pin 2722, an elastic element 2723, and a locking cover 2724. The snap-fit ​​base 2721 has a groove on its end face near the snap-fit ​​sleeve 271. The snap-fit ​​pin 2722 is slidably disposed in the groove, and the elastic element 2723 is disposed within the groove, possessing an elastic force that pushes the snap-fit ​​pin 2722 toward a direction away from the center of the snap-fit ​​base 2721. There can be two grooves located on the same straight line, and each groove is provided with a snap-fit ​​pin 2722 and an elastic element 2723.

[0085] In one embodiment, the elastic element 2723 is a compression spring, so that the elastic element 2723 has an elastic force to push the locking pin 2722 toward a direction away from the center of the locking seat 2721. The locking cover 2724 has an open end face and is clamped to the locking seat 2721. The locking cover 2724 and the locking seat 2721 are detachably connected by bolts, so that the locking cover 2724 can limit the locking pin 2722 and the elastic element 2723, improving the problem of the locking pin 2722 and the elastic element 2723 popping out.

[0086] When it is necessary to lock the snap-fit ​​connector 272 to the snap-fit ​​sleeve 271, the snap-fit ​​connector 272 is aligned with the receiving cavity of the snap-fit ​​sleeve 271, and the snap-fit ​​pin 2722 is pushed towards the center of the snap-fit ​​base 2721, so that the snap-fit ​​pin 2722 slides in the groove and presses against the elastic element 2723. Since the locking cover 2724 is clamped in the snap-fit ​​base 2721, the locking cover 2724 can limit the snap-fit ​​pin 2722 and the elastic element 2723, improving the problem of the snap-fit ​​pin 2722 and the elastic element 2723 popping out. By pushing the snap-fit ​​connector 272 into the receiving cavity of the snap-fit ​​sleeve 271, the elastic element 2723 pushes the snap-fit ​​pin 2722 into the locking hole 2711, thereby completing the snap-fit ​​of the first protective section 25 and the second protective section 26. When it is necessary to unlock the first protective section 25 and the second protective section 26, the locking pin 2722 can be pushed out from the locking hole 2711 to separate the locking connector 272 and the locking sleeve 271.

[0087] In addition, those skilled in the art may make other changes within the spirit of this application. Of course, all such changes made in accordance with the spirit of this application should be included within the scope disclosed in this application.
