Description

Technical Field

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

[0002] An all-terrain vehicle (ATV) is a vehicle designed to travel on a variety of complex terrains. ATVs have strong off-road capabilities and can easily handle complex terrains such as mud, sand, snow, and rocks.

[0003] All-terrain vehicles (ATVs) typically include a frame, body panels, running gear, suspension system, powertrain, transmission system, and fuel system. The body panels include an air intake grille at the front of the ATV, which supplies air to the radiator for cooling. However, in existing technologies, the air intake from the grille alone may be insufficient to meet the radiator's cooling requirements, thus reducing the radiator's cooling efficiency and consequently the ATV's overall cooling efficiency.

[0004] Therefore, improving the heat dissipation efficiency of all-terrain vehicles is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with high heat dissipation efficiency.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An all-terrain vehicle includes a frame, body panels, a running gear, a powertrain, and a cooling system. The body panels include an air intake grille located in front of the frame and a front cover for mounting the air intake grille. The front cover surrounds the air intake grille. The running gear is at least partially located below the frame. The powertrain is supported by the frame and driven by the running gear. The cooling system includes a radiator located behind the air intake grille. The front cover has cooling vents for delivering outside air to the radiator. The cooling vents are located above the air intake grille and at least partially face the front of the all-terrain vehicle. Along the length of the frame, the cooling vents and the radiator at least partially overlap.

[0008] Furthermore, the foremost part of the heat dissipation hole is located above the rearmost part of the heat dissipation hole.

[0009] Furthermore, a reference plane is defined perpendicular to the height direction of the vehicle frame. The front cover includes a heat dissipation plane. The angle between the reference plane and the heat dissipation plane ranges from 5° to 11°. The opening of the angle is set facing forward, and the heat dissipation holes are opened on the heat dissipation plane.

[0010] Furthermore, the all-terrain vehicle includes a front-mounted camera, and the heat dissipation plane includes a first heat dissipation area, a second heat dissipation area, and a mounting area for mounting the front-mounted camera. Both the first and second heat dissipation areas are provided with heat dissipation holes, and the mounting area is located between the first and second heat dissipation areas along the width direction of the vehicle frame.

[0011] Furthermore, at least a portion of the heat dissipation plane located in front of the heat dissipation hole is defined as a first guide surface, which can guide external air into the heat dissipation hole.

[0012] Furthermore, the body panels and frame form a front space, which is located behind the air intake grille and connects to the outside. The radiator is located within the front space, and the heat dissipation vents connect to the outside and the front space.

[0013] Furthermore, the front cover includes a side grille connecting the outside and the front space, a first side panel and a second side panel distributed along the width direction of the vehicle frame, the first side panel and the second side panel being at least partially located behind the radiator, and both the first side panel and the second side panel are provided with side grilles, which can transport the air behind the cooling radiator in the front space to the outside.

[0014] Furthermore, at least a portion of the heat dissipation plane located behind the heat dissipation hole is defined as a second guide surface, which can guide external airflow to the air intake grille.

[0015] Furthermore, the installation area has a third guide surface that can guide external air to the air intake grille.

[0016] Furthermore, the all-terrain vehicle also includes spotlights to improve the vehicle's lighting brightness. The spotlights are located at least partially above the heat dissipation vents, which allow outside air to be supplied to the spotlights.

[0017] In the aforementioned all-terrain vehicles, the air intake at the air intake grille can be increased through the heat dissipation holes, thereby improving the heat dissipation efficiency of the radiator and thus improving the overall heat dissipation efficiency of the all-terrain vehicle.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, an all-terrain vehicle 100 includes a frame 11, body panels 12, a running gear 13, a suspension system 14, a powertrain 15, and an electrical system 18.

[0032] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.

[0033] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panels 12, the running gear 13, the suspension system 14, the powertrain 15, and the electrical system 18. The body panels 12 are at least partially located on and connected to the frame 11, protecting the internal components of the all-terrain vehicle 100. The running gear 13 is at least partially located below the frame 11, and the suspension system 14 connects the running gear 13 to the frame 11. Specifically, the running gear 13 includes a front wheel 131 and a rear wheel 132, both at least partially located below the frame 11 and connected to the frame 11 via the suspension system 14. The powertrain 15 is drive-connected to the running gear 13. More specifically, the powertrain 15 can be driven to the front wheel 131, the powertrain 15 can be driven to the rear wheel 132, or the powertrain 15 can be driven to both the front wheel 131 and the rear wheel 132 simultaneously. The electrical system 18 is supported by the frame 11 and is used to display the driving data of the all-terrain vehicle 100, control the operation of the all-terrain vehicle 100, etc. The electrical system 18 is also at least partially connected to the body panel 12.

[0034] Specifically, the frame 11 includes a front frame 111, a middle frame 112, and a rear frame 113 connected in sequence. Along the length of the frame 11, the middle frame 112 is located between the front frame 111 and the rear frame 113, that is, the middle frame 112 is located behind the front frame 111 and in front of the rear frame 113. The body panel 12 and the middle frame 112 form a driver's cab 20, which provides seating space for the driver and / or passengers.

[0035] like Figure 3 and Figure 4 As shown, in one embodiment, the all-terrain vehicle 100 also includes a heat dissipation assembly 27. The heat dissipation assembly 27 is used to dissipate heat from the components of the all-terrain vehicle 100 to prevent damage due to overheating, thereby enabling stable operation of the all-terrain vehicle 100 and extending its service life. The body panel 12 includes an air intake grille 12a and a front cover 120. The air intake grille 12a is at least partially fixed to the frame 11 and is used to deliver external air to the heat dissipation assembly 27 to improve its heat dissipation efficiency. The front cover 120 is located in front of the frame 11 and is used to mount the air intake grille 12a. The front cover 120 surrounds the air intake grille 12a. The heat dissipation assembly 27 includes a radiator 271 located behind the air intake grille 12a, which is used for heat dissipation of the all-terrain vehicle 100.

[0036] Specifically, the front cover 120 is provided with heat dissipation holes 1201, which can deliver external air to the radiator 271. With this configuration, the heat dissipation holes 1201 can increase the air intake at the air intake grille 12a, thereby improving the heat dissipation efficiency of the radiator 271.

[0037] More specifically, the heat dissipation vent 1201 is located above the air intake grille 12a and at least partially faces the front of the all-terrain vehicle 100. Along the length of the frame 11, the heat dissipation vent 1201 at least partially overlaps with the radiator 271. This arrangement allows air to enter through the heat dissipation vent 1201 and flow directly toward the radiator 271 during the movement of the all-terrain vehicle 100, thereby improving the heat dissipation efficiency of the radiator 271.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the heat dissipation hole 1201 is arranged downwards, and the foremost part of the heat dissipation hole 1201 is at least partially located above the rearmost part of the heat dissipation hole 1201. This arrangement allows an upwardly inclined air intake channel to be formed at the inlet of the heat dissipation hole 1201, thereby avoiding the horizontally arranged heat dissipation hole 1201 from obstructing the air intake, thus improving the air intake efficiency of the heat dissipation hole 1201, and further facilitating the air to pass through the heat dissipation hole 1201 and dissipate heat within the radiator 271.

[0039] In this embodiment, a reference plane 101 is defined perpendicular to the height direction of the frame 11. The front cover 120 includes a heat dissipation plane 1202, and the included angle Φ between the reference plane 101 and the heat dissipation plane 1202 ranges from 5° to 11°. The opening of the included angle Φ faces forward, and the heat dissipation hole 1201 is formed on the heat dissipation plane 1202. Specifically, the included angle Φ between the reference plane 101 and the heat dissipation plane 1202 ranges from 6° to 10°. More specifically, the included angle Φ between the reference plane 101 and the heat dissipation plane 1202 is 8°. This arrangement avoids an excessively large included angle Φ between the reference plane 101 and the heat dissipation plane 1202, which would prevent the heat dissipation plane 1202 from failing to deliver air to the upwardly tilted air intake channel. This improves the air intake efficiency of the air intake channel at the heat dissipation hole 1201, thereby enhancing the heat dissipation effect of the radiator 271. In addition, it can also avoid the angle Φ between the reference plane 101 and the heat dissipation plane 1202 being too small, which would cause the front cover 120 to block the air intake of the heat dissipation hole 1201, thereby helping to increase the air intake of the heat dissipation hole 1201 and thus improve the heat dissipation effect of the radiator 271.

[0040] like Figure 3As shown, in one embodiment, the electrical system 18 includes a front-facing camera 184 for monitoring the environment in front of the all-terrain vehicle 100. Specifically, the heat dissipation plane 1202 includes a first heat dissipation area 1202a, a second heat dissipation area 1202b, and a mounting area 1202c. The mounting area 1202c is used to mount the front-facing camera 184. Both the first heat dissipation area 1202a and the second heat dissipation area 1202b have heat dissipation holes 1201 distributed thereon. The mounting area 1202c is located between the first heat dissipation area 1202a and the second heat dissipation area 1202b along the width direction of the frame 11. With this arrangement, the heat dissipation holes 1201 of the first heat dissipation area 1202a and the second heat dissipation area 1202b will not interfere with the front-facing camera 184, thereby facilitating the assembly of the front-facing camera 184 with the front cover 120.

[0041] like Figure 4 , Figure 5 and Figure 6 As shown, as an optional implementation, at least a portion of the heat dissipation plane 1202 located in front of the heat dissipation hole 1201 is defined as a first guide surface 1202d. The first guide surface 1202d can guide external air into the heat dissipation hole 1201, thereby further increasing the air intake of the heat dissipation hole 1201.

[0042] Specifically, the body panel 12 and the frame 11 form a front space 107, which is located behind the air intake grille 12a and communicates with the outside. The radiator 271 is located inside the front space 107, and the heat dissipation vents 1201 connect the outside and the front space 107. This arrangement allows outside air to enter the front space 107 through the heat dissipation vents 1201, cool the radiator 271 located in the front space 107, and then circulate back to the outside, thus realizing a circulation path of airflow through the radiator 271 and improving the heat dissipation efficiency of the radiator 271.

[0043] In this embodiment, the front cover 120 includes a side grille 1202g that connects the outside world and the front space 107, a first side plate 1202h and a second side plate (not shown) distributed along the width direction of the frame 11. The first side plate 1202h and the second side plate are at least partially located behind the radiator 271. The side grille 1202g is provided on both the first side plate 1202h and the second side plate. The side grille 1202g can transport the air in the front space 107 that cools the radiator 271 to the outside world, thereby realizing the circulation path of air flowing through the radiator 271.

[0044] More specifically, at least a portion of the heat dissipation plane 1202 located behind the heat dissipation hole 1201 is defined as the second guide surface 1202e. The second guide surface 1202e can guide external air to the air intake grille 12a, thereby guiding air that has not entered the heat dissipation hole 1201 to the air intake grille 12a, thereby increasing the air intake volume of the air intake grille 12a and thus improving the heat dissipation efficiency of the radiator 271 in the front space 107.

[0045] In one implementation, the mounting area 1202c is provided with a third guide surface 1202f, which guides external airflow to the air intake grille 12a. This configuration increases the amount of air entering the front space 107 from the outside through the air intake grille 12a via the third guide surface 1202f, thereby further improving the heat dissipation effect of the radiator 271 within the front space 107.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, the all-terrain vehicle 100 also includes a spotlight 213, which is used to improve the illumination brightness of the all-terrain vehicle 100. The spotlight 213 is at least partially located above a heat dissipation vent 1201, which allows external air to be supplied to the spotlight 213. This arrangement allows the spotlight 213 to be cooled by the air supplied through the heat dissipation vent 1201, preventing the spotlight 213 from overheating and being damaged, thereby extending its service life.

[0047] In this embodiment, the all-terrain vehicle 100 also includes a first light 211 and a second light 212, which are distributed along the width direction of the frame 11. A spotlight 213 is located between the first light 211 and the second light 212. This arrangement, through the spotlight 213 working in conjunction with the first light 211 and the second light 212, increases the illumination brightness of the all-terrain vehicle 100, thereby improving its safety in low-light conditions.

[0048] like Figure 7 As shown, in one embodiment, the body panel 12 includes a spoiler 12b, which reduces air resistance on the all-terrain vehicle 100, thereby reducing the energy consumption of the all-terrain vehicle 100 and increasing its travel speed. The all-terrain vehicle 100 also includes a rear windshield assembly 28, which is located at the rear of the frame 11 and connected to the frame 11.

[0049] Specifically, the all-terrain vehicle 100 includes fasteners 10e, a rear windshield assembly 28 rotatably connected to the frame 11, and a spoiler 12b fixed to the rear windshield assembly 28 by fasteners 10e. The spoiler 12b is also at least partially located above the rear windshield assembly 28, and the spoiler 12b is able to rotate behind the rear windshield assembly 28. This arrangement avoids interference from the spoiler 12b with the rotation of the rear windshield assembly 28, thus preventing the rear windshield assembly 28 from being restricted in its rotation, thereby facilitating the deployment and closure of the rear windshield assembly 28 and improving its operational stability.

[0050] As an optional implementation, the rear windshield assembly 28 includes a connecting upper end 281, which is rotatably connected to the frame 11, and the spoiler 12b is fixed to the connecting upper end 281. This arrangement allows the spoiler 12b to be positioned above the rear windshield assembly 28, thereby preventing the rear windshield assembly 28 from obstructing the spoiler 12b and enabling the spoiler 12b to function properly.

[0051] Specifically, the rear windshield assembly 28 includes a lower connecting end 282, which has a fixed state where it is fixed to the frame 11 and a disengaged state where it is detached from the frame 11. This configuration allows the lower connecting end 282 of the rear windshield assembly 28 to be fixed to and detached from the frame 11.

[0052] More specifically, the lower connection 282 includes a fixing structure 2821, which is detachably connected to the frame 11 and can be fixed or separated from the frame 11. This configuration allows for the fixing and separation of the rear windshield assembly 28 and the frame 11 via the fixing structure 2821, thereby simplifying the connection structure between the rear windshield assembly 28 and the frame 11 and improving the ease of rotation and installation of the rear windshield assembly 28.

[0053] like Figure 7 and Figure 8 As shown, in one embodiment, the fixing structure 2821 includes a through-hole portion 2821a and a snap-fit ​​portion 2821b. The snap-fit ​​portion 2821b is connected to the through-hole portion 2821a, and the through-hole portion 2821a at least partially passes through the rear windshield assembly 28 and is rotatable relative to the rear windshield assembly 28. The snap-fit ​​portion 2821b has a snap-fit ​​groove 2821c, which is rotatable synchronously with the through-hole portion 2821a to form a first rotational position and a second rotational position. The through-hole component can be a bolt.

[0054] Specifically, when the locking slot 2821c is in the first rotational position, the frame 11 is at least partially located in the locking slot 2821c and locked in the locking slot 2821c. At this time, the lower connection end 282 is in a fixed state.

[0055] When the locking slot 2821c is in the second rotational position, the locking slot 2821c is separated from the frame 11, and at this time, the lower connection end 282 is in a separated state. With this configuration, by rotating the through part 2821a, the locking part 2821b can rotate together with the through part 2821a, thereby allowing the locking part 2821b to switch between the first rotational position and the second rotational position, so that the locking part 2821b can cooperate with the frame 11 for connection and separation.

[0056] More specifically, the frame 11 and body panel 12 form a driver's cab 20. The latching part 2821b is located inside the driver's cab 20. The fixing structure 2821 also includes an operating part 2821d connected to the through part 2821a. The operating part 2821d is located outside the driver's cab 20 and can drive the through part 2821a to rotate. With this configuration, rotating the operating part 2821d outside the driver's cab 20 can drive the through part 2821a to rotate, thereby driving the latching part 2821b to rotate, allowing the latching part 2821b to switch between a first rotation position and a second rotation position. This configuration improves the ease of assembly and disassembly of the rear windshield assembly 28 from the frame 11.

[0057] like Figure 7 As shown, in one embodiment, the rear windshield assembly 28 also includes a telescopic rod 283 and a rear windshield 284. The telescopic rod 283 supports the rear windshield 284 when it is open, thereby keeping the rear windshield 284 open. Specifically, one end of the telescopic rod 283 is rotatably connected to the rear windshield 284, and the other end of the telescopic rod 283 is rotatably connected to the vehicle frame 11. The end of the telescopic rod 283 connected to the rear windshield 284 is higher than the end of the telescopic rod 283 connected to the vehicle frame 11. With this configuration, when the rear windshield 284 is rotated, the telescopic rod 283 can be driven to extend or retract, so that the telescopic rod 283 can support the rear windshield 284 at different positions.

[0058] More specifically, the end of the telescopic rod 283 that connects to the rear windshield 284 is located between the upper connection end 281 and the lower connection end 282. This arrangement avoids the telescopic rod 283 being positioned above the upper connection end 281, which would prevent the rear windshield 284 from opening, thus facilitating the rotation of the rear windshield 284; it also avoids the telescopic rod 283 being positioned below the lower connection end 282, which would prevent it from failing to support the rear windshield 284, thus facilitating the support of the rear windshield 284 after it is opened.

[0059] In one implementation, the all-terrain vehicle 100 includes a canopy mechanism 29 (see reference). Figure 6The roof mechanism 29 is located above the vehicle frame 11, and the spoiler 12b is at least partially located above the roof mechanism 29. This arrangement allows the spoiler 12b to turbulently circulate the air above the roof mechanism 29, thereby reducing the air resistance experienced by the all-terrain vehicle 100 and enabling the spoiler 12b to function properly.

[0060] like Figure 7 As shown, in one embodiment, the fastener 10e is a bolt, and the spoiler 12b is provided with a fixing bracket 12ba. The fixing bracket 12ba is fixedly connected to the rear windshield assembly 28 by the fastener. By connecting the rear windshield assembly 28 to the fixing bracket 12ba with bolts, the connection stability between the spoiler 12b and the rear windshield assembly 28 is improved.

[0061] In this embodiment, when the rear windshield assembly 28 is closed, the fixed bracket 12ba is at least partially located below the spoiler 12b. This arrangement allows the spoiler 12b to be at least partially located above the all-terrain vehicle 100, enabling the spoiler 12b to turbulentize the air above the all-terrain vehicle 100, thereby reducing air resistance on the all-terrain vehicle 100 and helping to reduce the energy consumption of the all-terrain vehicle 100.

[0062] like Figure 9 and Figure 10 As shown, the all-terrain vehicle 100 includes a seat 19 mounted on a frame 11 for supporting the driver and / or passenger. The seat 19 includes a driver's seat (not shown) and a front passenger seat (not shown). The all-terrain vehicle 100 also includes an armrest mechanism 30 located in front of the front passenger seat. The armrest mechanism 30 includes a rotating bracket 31, an armrest frame 32, and an adjustment assembly 33. The rotating bracket 31 is mounted on the frame 11; alternatively, at least one end of the rotating bracket 31 is fixed to a body panel 12, with the body panel 12 providing support for the rotating bracket 31. The armrest frame 32 is rotatably connected to the frame 11 via the rotating bracket 31. The armrest frame 32 is available for occupant gripping; when the occupant is in the seat 19, they grip the armrest frame 32 to ensure their safety. The adjustment assembly 33 is used to adjust the position of the armrest frame 32.

[0063] Among them, the rotating bracket 31 can be a metal tube extending along the width direction of the frame 11, and the handrail 32 is U-shaped and can be gripped by passengers.

[0064] Specifically, the adjustment assembly 33 includes an adjustment body 330, a telescopic member 331, a locking member 332, a cable 333, and a switch 334. The adjustment body 330 is rotatably connected to the frame 11. The telescopic member 331 is rotatably connected to the rotating bracket 31. The locking member 332 is used to fix or unlock the relative position of the telescopic member 331 and the adjustment body; that is, the locking member 332 can lock the telescopic member 331 to fix it, and the locking member 332 can also be separated from the telescopic member 331 to allow it to move. The cable 333 is drively connected to the locking member 332. The switch 334 controls the cable 333, which in turn controls the locking member 332, so that the locking member 332 can fix or unlock the relative position of the telescopic member 331 and the adjustment body 330.

[0065] With the above settings, the switch 334 controls the locking member 332 to unlock via the pull cable 333, thereby adjusting the relative position of the telescopic member 331 and the adjusting body 330, and further adjusting the position of the rotating bracket 31 to adjust the position of the armrest 32. This ensures that the height of the armrest 32 is adapted to the height and build of the passenger in the front passenger seat, thus preventing the armrest 32 from being too high and making it difficult for the passenger to hold it, and also preventing the armrest 32 from being too low and interfering with the passenger's seating in the front passenger seat, thereby improving the passenger's seating comfort.

[0066] Secondly, when passengers in the front passenger seat get on and off the vehicle, the handrail 32 can be rotated so that it rotates away from the front passenger seat, thereby avoiding interference between the handrail 32 and the passenger and making it easier for the passenger to get on and off the vehicle.

[0067] In this embodiment, the cable 333 has a preset length, which allows the position of the switch 334 to be adjusted. With this configuration, by adjusting the preset length, the installation position of the switch 334 in the all-terrain vehicle 100 can be adjusted. This allows the switch 334 to be installed in available space within the driver's cab 20, or it can be positioned for easy passenger operation, ensuring that the installation position of the switch 334 meets usage requirements.

[0068] In one implementation, the telescopic member 331 can move along the extending direction of the adjusting body 330, so that when adjusting the position of the handrail 32, the telescopic member 331 can be moved by rotating the bracket 31. Specifically, the locking member 332 includes an adjusting state and a locking state. When the locking member 332 is in the adjusting state, the locking member 332 is separated from the telescopic member 331, so that the telescopic member 331 can move along the extending direction of the adjusting body 330. At this time, the rotating bracket 31 can rotate relative to the frame 11, which is beneficial for adjusting the position of the handrail 32. It should be noted that the adjusting body 330 is a rod-shaped structure, and the extending direction of the adjusting body 330 is the extending direction of the rod-shaped structure.

[0069] When the locking member 332 is in the locked state, the locking member 332 locks the position of the telescopic member 331 relative to the adjustment body 330, and the rotating bracket 31 is fixed relative to the frame 11.

[0070] In one implementation, the cable 333 can extend the distance between the switch element 334 and the locking element 332, making the position of the switch element 334 adjustable. The installation location of the switch element 334 includes, but is not limited to, the frame 11, the seat 19, and the body panel 12; this application does not specifically limit the installation location of the switch element 334. This arrangement allows the switch element 334 to be positioned away from the adjustment assembly 33, enabling it to be placed in a more convenient location for occupant operation, thus improving occupant comfort. Furthermore, the installation location of the switch element 334 is more flexible, improving the rational utilization of vehicle space.

[0071] In one implementation, the switch 334 includes a fixed unit 3341 and a movable unit 3342. The fixed unit 3341 is mounted on the vehicle frame 11 or the seat 19, so that the fixed unit 3341 remains stationary when the occupant operates the switch 334. The movable unit 3342 is movably connected to the fixed unit 3341, and an adjustable angle is formed between the movable unit 3342 and the fixed unit 3341. One end of the cable 333 is connected to the movable unit 3342.

[0072] Specifically, both the fixed unit 3341 and the movable unit 3342 are configured as metal plate-shaped components, which makes the service life of the switch 334 longer, and the end face area of ​​the movable unit 3342 facing the occupant side that can be pressed by the occupant is larger, reducing the difficulty of operating the switch 334.

[0073] like Figure 11As shown, further, the adjustment component 33 has a fixing member 335 at one end near the handrail frame 32. The fixing member 335 can be a sheet metal integrally formed with the adjustment component 33, or it can be a sheet metal snapped onto the adjustment component 33. The installation method of the fixing member 335 is not specifically limited. The cable 333 includes a flexible hose 3421 and a metal rope 3422 passing through the flexible hose 3421. One end of the flexible hose 3421 is connected to the fixing member 335, and the other end is connected to the fixing unit 3341. One end of the metal rope 3422 is connected to the locking member 332, and the other end is connected to the movable unit 3342. The two ends of the flexible hose 3421 are respectively fixed to the fixing member 335 and the fixing unit 3341.

[0074] To clearly illustrate the technical solution of this application, the two opposite ends of the flexible hose 3421 are defined as the first end 3421a and the second end 3421b, respectively, and the two opposite ends of the metal rope 3422 are defined as the third end 3422a and the fourth end 3422b, respectively. The first end 3421a and the third end 3422a are close to each other, and the second end 3421b and the fourth end 3422b are also close to each other. The first end 3421a is installed on the fixing unit 3341, the second end 3421b is installed on the fixing member 335, the third end 3422a is installed on the moving unit 3342, and the fourth end 3422b is installed on the locking member 332. When the movable unit 3342 rotates relative to the fixed unit 3341, the movable unit 3342 drives the metal rope 3422 to move relative to the flexible hose 3421, that is, the distance between the first end 3421a and the third end 3422a increases. Since the two ends of the flexible hose 3421 are respectively fixed to the fixing member 335 and the fixed unit 3341, that is, the relative position of the third end 3422a and the fourth end 3422b remains unchanged, the distance between the second end 3421b and the fourth end 3422b decreases, thereby driving the locking member 332 to move, so that the locking member 332 is in an adjustable state, and the handrail frame 32 can rotate relative to the rotating bracket 31.

[0075] As an optional implementation, the all-terrain vehicle 100 also includes a center console 124, on which a switch 334 is mounted. The switch 334 is a button. When the button is triggered, the switch 334 moves the locking member 332 via the pull cable 333, so that the locking member 332 is in an adjustable state, and the handrail 32 can rotate relative to the rotating bracket 31.

[0076] As an alternative implementation, the switch 334 includes a signal generator, a signal line, and a drive motor. The signal transmitter is electrically connected to the drive motor via the signal line. The drive motor is configured to control the locking element 332 to switch between an adjustable state and a locked state. The signal generator generates an electrical signal upon triggering by an occupant. This signal is transmitted to the drive motor via the signal line, and the drive motor controls the locking element 332 to switch from a locked state to an adjustable state, allowing the handrail 32 to rotate relative to the rotating support 31 circumferentially.

[0077] In one implementation, the adjusting component 33 is a pneumatic spring. It should be noted that the adjusting component 33 can also be any type of pneumatic pilot-operated pressure reducing valve.

[0078] In one implementation, the rotating support 31 includes an outer tube 311 connected to the handrail frame 32 and an inner tube 312 located within the outer tube 311, both of which are tubular components. Specifically, the outer tube 311 is rotatably connected to the telescopic member 331, and the inner tube 312 is rotatable within the outer tube 311, with both ends of the inner tube 312 extending out of the outer tube 311 and connected to the frame 11. This arrangement fixes the inner tube 312 to the frame 11, and the handrail frame 32 is rotatably connected to the inner tube 312 via the outer tube 311.

[0079] like Figure 12 As shown, optionally, the rotating bracket 31 is configured as a metal tube. The rotating bracket 31 includes a fixed tube 314 and a bearing 313. The fixed tube 314 is connected to the frame 11. The bearing 313 includes an inner ring and an outer ring. The inner ring is sleeved on the fixed tube 314 and connected to the fixed tube 314. The outer ring is connected to the handrail 32 and is also rotatably connected to the telescopic member 331.

[0080] It should be noted that the above are only two preferred implementation methods, which are any connection methods that enable the rotating bracket 31 and the handrail 32 to rotate relative to each other. This application does not make specific limitations on the connection method between the two.

[0081] like Figure 11 As shown, the handrail mechanism 30 also includes a movable bolt 322 and a sheet metal part 321, which is connected to the rotating bracket 31. In some embodiments, the sheet metal part 321 is welded to the rotating bracket 31 to ensure the connection strength between the sheet metal part 321 and the rotating bracket 31. The movable bolt 322 passes through the sheet metal part 321 and is rotatably connected to the telescopic member 331.

[0082] In one implementation, the front frame 111 includes a first mounting bracket 1111, which distinguishes the seats 19 into front seats and rear seats according to their installation positions. The first mounting bracket 1111 is located in front of the front seats, and the rotating bracket 31 is fixedly connected to the first mounting bracket 1111. This allows the occupant in the front seat to grasp the armrest bracket 32 ​​mounted on the first mounting bracket 1111.

[0083] Optionally, the center frame 112 includes a second mounting bracket (not shown), which can be fixed to the rear of the front seats, and the rotating bracket 31 is fixedly connected to the second mounting bracket. This allows occupants in the rear seats to grasp the armrest bracket 32 ​​mounted on the second mounting bracket.

[0084] In the embodiments of this application, the armrest mechanism 30 further includes a plurality of limiting members 343, and the cable 333 is fixed on the limiting members 343. The installation position of the limiting members 343 includes at least one of the adjusting body 330, the body cover 12 and the seat 19.

[0085] The cable 333 is limited by several limiting members 343, allowing it to extend from the first mounting bracket 1111 towards the front seat in a preset direction, or from the second mounting bracket towards the rear seat in a preset direction. This prevents the extended cable 333 from being exposed in the cockpit and affecting the passenger experience.

[0086] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
