Description

Technical Field

[0001] This invention relates to an all-terrain vehicle seat. Background Technology

[0002] All-terrain vehicles (ATVs) are practical vehicles adapted to complex terrains such as mountains, forests, and sandy areas, combining multiple functions including leisure, competition, and work. With a robust structure and flexible handling, they not only meet off-road entertainment needs but also assist in various scenarios such as agricultural and forestry transportation, fire rescue, and military patrols, making them a versatile off-road motorized vehicle.

[0003] All-terrain vehicles are typically used in areas with poor road conditions. Therefore, the seats in all-terrain vehicles, which serve as the support structure for the driver, require a high level of comfort.

[0004] However, existing all-terrain vehicle seats are typically fixed, and the distance between the seat and the steering handlebars is not easily adjustable to suit different drivers, resulting in poor driving adaptability. Furthermore, the twisting motion of the driver's lower back during turns can easily cause muscle strain. Simultaneously, maintaining the driver's body during turns is difficult, and the centrifugal force generated can easily cause the driver's body to shift, potentially leading to loss of control and, in severe cases, even ejection from the vehicle, significantly reducing driving safety and handling stability. Therefore, to address these technical problems, an all-terrain vehicle seat is proposed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention proposes an all-terrain vehicle seat that offers high driver adaptability. It allows the driver's body to rotate with the direction of the turn, reducing lumbar twisting, preventing muscle strain, and facilitating the maintenance of the driver's body during turns to prevent deviation, thereby improving driving safety and handling stability.

[0006] An all-terrain vehicle seat, comprising: The base is mounted on the frame in an adjustable position along the length of the frame; The seat body includes a seat plate rotatably disposed at the top of the base, and a back plate disposed at one end of the seat plate; A first transmission mechanism connects the seat and the steering handle, used to convert rotation of the steering handle into rotation of the seat in the same direction; and The protective mechanism includes a guard plate and a second transmission mechanism. The guard plates are slidably arranged on both sides of the back plate. The second transmission mechanism connects the base and the two sets of guard plates and is used to drive the two sets of guard plates to slide out of the back plate toward the steering handle or retract into the back plate when the seat plate rotates or returns to center.

[0007] The beneficial effects of the aforementioned all-terrain vehicle seat are as follows: The distance between the seat and the steering handlebars can be adjusted by changing the position of the base along the length of the frame, making it easy to adjust for different drivers and providing high driving adaptability. When the steering handlebars turn, they drive the seat to rotate in the same direction via the first transmission mechanism. At this time, the seat rotates the driver's body, which reduces the twisting of the driver's waist and avoids muscle strain. At the same time, during the rotation of the seat, the seat drives two sets of guard plates to extend towards the steering handlebars via the second transmission mechanism. The two sets of guard plates can then abut against the sides of the driver's body, which helps to keep the driver's body in place during turns, prevent deviation, and improve driving safety and handling stability. When the seat returns to center, the seat drives the two sets of guard plates to retract into the back panel via the second transmission mechanism, thereby eliminating the abutment against the sides of the driver's body and ensuring the driver's body flexibility during straight-line driving.

The seat cushion is arranged at the top of both sets of limiting blocks. When the fixing shaft is inserted into the fixing hole, the seat cushion is pressed so that the top surfaces of the two sets of limiting blocks are flush with the top surface of the seat plate, and the bottom ends of the two sets of limiting blocks abut against the opposite sides of the two sets of fixing plates.

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0021] Please see Figure 1 and Figure 2 In one embodiment, an all-terrain vehicle seat includes a base 10, a seat body, a first transmission mechanism, and a protective mechanism. The base 10 is adjustable in position along the length of the vehicle frame 1. The seat body includes a seat plate 20 rotatably mounted on the top of the base 10 and a backrest 201 mounted on one end of the seat plate 20. The first transmission mechanism connects the seat plate 20 and the steering handle 2, converting rotation of the steering handle 2 into rotation of the seat plate 20 in the same direction. The protective mechanism includes guard plates 30 and a second transmission mechanism. Guard plates 30 are slidably mounted on both sides of the backrest 201. The second transmission mechanism connects the base 10 and the two sets of guard plates 30, driving the two sets of guard plates 30 to slide out of the backrest 201 towards the steering handle 2 or retract into the backrest 201 when the seat plate 20 rotates or returns to center.

[0022] In the above embodiment, the distance between the seat 20 and the steering handlebar 2 can be adjusted by adjusting the position of the base 10 along the length of the frame 1, which is convenient for adjustment according to different drivers and has high driving adaptability. When the steering handlebar 2 turns, the steering handlebar 2 drives the seat 20 to rotate in the same direction through the first transmission mechanism. At this time, the seat 20 drives the driver's body to rotate, which can reduce the twisting of the driver's waist and thus avoid muscle strain. At the same time, during the rotation of the seat 20, the seat 20 drives two sets of guard plates 30 to extend towards the back plate 201 of the steering handlebar 2 through the second transmission mechanism. The two sets of guard plates 30 can then abut against the sides of the driver's body, which helps to keep the driver's body in place during turning and prevents the body from shifting due to centrifugal force, thereby improving driving safety and handling stability. When the seat 20 returns to center, the seat 20 drives the two sets of guard plates 30 to retract into the back plate 201 through the second transmission mechanism to cancel the abutment against the sides of the driver's body, thereby ensuring the driver's body flexibility during straight driving.

[0023] Please see Figures 1 to 3In one embodiment, the base 10 further includes a fixing mechanism, which includes a fixing plate 40 and a driving member. The top of the base 10 has two sets of first guide grooves 101 facing each other. Each of the two sets of first guide grooves 101 is provided with a fixing plate 40 that slides along the width direction of the frame 1. Each of the two sets of fixing plates 40 has multiple sets of fixing shafts 401 on the opposite side. The frame 1 has multiple sets of fixing holes 11 facing each other along its length direction. The driving member is rotatably mounted on the base 10 and connected to the two sets of fixing plates 40. It is used to drive the two sets of fixing plates 40 to move away from or towards each other, so that the multiple sets of fixing shafts 401 can be inserted into or withdrawn from the multiple sets of fixing holes 11.

[0024] In the above embodiment, by moving the base 10, multiple sets of fixed shafts 401 are aligned with multiple sets of fixed holes 11 at different positions. Then, by rotating the drive component, the two sets of fixed plates 40 are moved away from each other. The movement of the two sets of fixed plates 40 away from each other allows the multiple sets of fixed shafts 401 to be inserted into the currently mating multiple sets of fixed holes 11 to fix the base 10. This allows the position of the base 10 to be adjusted along the length of the frame 1, thereby adjusting the distance between the seat 20 and the steering handle 2. Adjusting the distance between the seat 20 and the steering handle 2 is convenient.

[0025] Specifically, in the above embodiment, the driving component includes a bidirectional screw 402. The bidirectional screw 402 is arranged along the width direction of the frame 1 and is rotatably disposed within two sets of first guide grooves 101. Both ends of the bidirectional screw 402 are threadedly connected to two sets of fixing plates 40, respectively. By rotating the bidirectional screw 402 in both directions and engaging with the two sets of fixing plates 40, the two sets of fixing plates 40 can be driven to move relatively away from or closer to each other. This facilitates the convenient movement of the fixing plates 40, thereby enabling quick and easy fixing or releasing of the base 10.

[0026] Based on the above embodiments, the base 10 further includes two sets of positioning grooves 102 at its bottom end, which are slidably fitted onto the frame 1 along the length of the frame 1. Each of the two sets of positioning grooves 102 has multiple sets of through holes 103, and multiple sets of fixing shafts 401 can pass through the multiple sets of through holes 103 and be inserted into the multiple sets of fixing holes 11.

[0027] By opening two sets of positioning grooves 102, it is easy for the base 10 to slide along its length on the frame 1, and at the same time, it is easy to align multiple sets of fixing shafts 401 with multiple sets of fixing holes 11, thereby improving the convenience of fixing the base 10 to the frame 1.

[0028] Please see Figure 2 , Figure 4 and Figure 5In one embodiment, the fixing mechanism further includes a limiting component; the limiting component includes a limiting block 403, a spring 404, and a seat cushion 405; two sets of vertically penetrating slots 202 are provided opposite each other at the top of the seat plate 20, and the limiting blocks 403 are slidably arranged vertically in both sets of slots 202. Springs 404 are provided between the two ends of the limiting blocks 403 and the seat plate 20. The springs 404 are used to apply a vertically upward pushing force to the limiting blocks 403 so that the top of the limiting blocks 403 protrudes from the top surface of the seat plate 20. The top of the two sets of limiting blocks 403 is provided with a seat cushion 405. When the fixing shaft 401 is inserted into the fixing hole 11, the seat cushion 405 is pressed so that the top surface of the two sets of limiting blocks 403 is flush with the top surface of the seat plate 20, and the bottom ends of the two sets of limiting blocks 403 respectively abut against the opposite sides of the two sets of fixing plates 40.

[0029] In the above embodiment, when the driver sits on the seat cushion 405, the two sets of limiting blocks 403 move downwards to be flush with the seat plate 20 when the seat cushion 405 is pressed, and the bottom ends of the two sets of limiting blocks 403 abut against the opposite sides of the two sets of fixing plates 40 respectively. At this time, it can prevent the two sets of fixing plates 40 from moving closer to each other, thereby ensuring the stability of the base 10 fixed on the frame 1 during the driving process and avoiding the phenomenon of the base 10 becoming loose due to driving vibration.

[0030] Specifically, in the above embodiment, guide shafts 204 are vertically arranged at both ends of the two sets of through slots 202, and both ends of the two sets of limiting blocks 403 are sleeved on the two sets of guide shafts 204. The top ends of the four sets of guide shafts 204 are threadedly connected to limiting discs 205 that abut against the top ends of the limiting blocks 403. Springs 404 are sleeved on the four sets of guide shafts 204, with the two ends of the springs 404 abutting against the bottom ends of the limiting blocks 403 and the bottom of the guide shafts 204, respectively. By setting guide shafts 204 to guide the extension and retraction of springs 404, the service life of springs 404 can be improved. Furthermore, the limiting blocks 403 can be removed by disassembling the limiting discs 205, facilitating individual replacement of components and reducing replacement costs.

[0031] Please see Figure 1 , Figure 2 , Figure 6 and Figure 7In one embodiment, the first transmission mechanism includes a first rotating shaft 50, a second rotating shaft 501, a first bevel gear 502, a second bevel gear 503, a third bevel gear 504, and a fourth bevel gear 505. The first rotating shaft 50 is arranged along the length of the frame 1 and is rotatably mounted on the bottom end of the base 10. The first bevel gear 502 is coaxially mounted on one end of the first rotating shaft 50, and the second bevel gear 503 is coaxially mounted on the bottom end of the rotating shaft of the seat plate 20. The second bevel gear 503 meshes with the first bevel gear 502. The second rotating shaft 501 is coaxially mounted with the first rotating shaft 50 and is rotatably mounted on the frame 1. One end of the second rotating shaft 501 slides through the other end of the first rotating shaft 50, and the third bevel gear 504 is coaxially mounted on the other end of the second rotating shaft 501. The fourth bevel gear 505 is coaxially mounted on the transmission shaft 21 in the steering handle 2 and meshes with the third bevel gear 504.

[0032] In the above embodiment, the rotation of the steering handle 2 drives the second rotating shaft 501 to rotate the first rotating shaft 50 in the opposite direction relative to the steering handle 2 through the meshing of the fourth bevel gear 505 and the third bevel gear 504. The rotation of the first rotating shaft 50 drives the seat plate 20 to rotate in the opposite direction relative to the first rotating shaft 50 through the meshing of the first bevel gear 502 and the second bevel gear 503, thereby making the seat plate 20 rotate in the same direction as the steering handle 2. It is convenient for the steering handle 2 to drive the seat plate 20 to rotate in the same direction.

[0033] Please see Figure 2 and Figure 4 In one embodiment, guide grooves 203 are provided at both ends of the back plate 201 facing the steering handle 2, and two sets of guard plates 30 are slidably disposed in the two sets of guide grooves 203 along the thickness direction of the back plate 201, ensuring the stability of the sliding of the two sets of guard plates 30.

[0034] Please see Figure 6 and Figure 8 In one embodiment, the second transmission mechanism includes a connecting rod 301, a guide rod 302, and a V-shaped guide groove 303. The bottom ends of both sets of guard plates 30 are connected to the connecting rod 301, the guide rod 302 is located in the middle of the connecting rod 301, and the top of the base 10 has a V-shaped guide groove 303. The guide rod 302 is slidably disposed within the V-shaped guide groove 303. It can be understood that when the seat plate 20 is in the centered state, the guide rod 302 is located in the middle of the V-shaped guide groove 303.

[0035] In the above embodiment, when the seat 20 rotates, the seat 20 drives the two sets of guard plates 30 and the connecting rod 301 to rotate. The rotation of the connecting rod 301 drives the guide rod 302 to slide along one side of the V-shaped guide groove 303, which in turn drives the connecting rod 301 to move. The movement of the connecting rod 301 drives the two sets of guard plates 30 to move and extend out of the back plate 201. When the seat 20 rotates back to the center, the guide rod 302 slides along one side of the V-shaped guide groove 303 in the opposite direction, which drives the connecting rod 301 to move in the opposite direction. The movement of the connecting rod 301 in the opposite direction drives the two sets of guard plates 30 to move in the opposite direction and retract into the back plate 201. It is convenient to drive the two sets of guard plates 30 to extend or retract into the back plate 201, and no additional power equipment is required.

[0036] Please see Figure 6 and Figure 8 In one embodiment, the protective mechanism further includes an airbag 304 and an inflation assembly; each of the two sets of protective plates 30 has a placement groove 305 on its opposite side, and each of the two sets of placement grooves 305 is provided with an airbag 304. The inflation assembly connects the seat plate 20, the connecting rod 301 and the airbag 304, and is used to drive the two sets of airbags 304 to expand or contract when the two sets of protective plates 30 extend or retract.

[0037] In the above embodiment, the two sets of protective plates 30 extend out of the back plate 201 and drive the two sets of airbags 304 to inflate through the inflation component. The inflating of the two sets of airbags 304 can prevent the driver's body from directly hitting the protective plates 30 and improve the driver's comfort.

[0038] Specifically, in the above embodiments, the inflation assembly includes a piston cylinder 306, a piston 307, and a piston rod 308; two sets of piston cylinders 306 are arranged opposite to each other on the connecting rod 301, and a piston 307 is slidably and sealed inside one end of each set of piston cylinders 306. Both sets of pistons 307 are connected to the seat plate 20 through the piston rod 308, and the other ends of the two sets of piston cylinders 306 are connected to the two sets of airbags 304 respectively through the connecting pipe 309.

[0039] In the above embodiment, when the connecting rod 301 moves to extend the two sets of protective plates 30 out of the back plate 201, the connecting rod 301 drives the two sets of piston cylinders 306 to move. The movement of the two sets of piston cylinders 306, in conjunction with the piston 307, allows the air inside the piston cylinders 306 to be transported to the airbag 304 through the connecting pipe 309, thereby causing the airbag 304 to inflate. When the connecting rod 301 moves in the opposite direction to retract the two sets of protective plates 30 into the back plate 201, the connecting rod 301 drives the two sets of piston cylinders 306 to move in the opposite direction, in conjunction with the piston 307, thereby drawing the air inside the airbag 304 back into the piston cylinders 306, thereby causing the airbag 304 to contract. This facilitates the expansion or contraction of the two sets of airbags 304 when the two sets of protective plates 30 extend or retract from the back plate 201, without the need for additional power equipment.

[0040] The specific implementation method of the above-mentioned all-terrain vehicle seat is as follows: By rotating the bidirectional screw 402 and engaging the threaded connection with the two sets of fixing plates 40, the two sets of fixing plates 40 can be driven to move closer to each other, thereby disengaging the multiple sets of fixing shafts 401 from the fixing holes 11 and releasing the fixing of the base 10. At this time, the base 10 can be moved along the length of the frame 1. When the base 10 is moved to the appropriate position, by rotating the bidirectional screw 402 in the opposite direction and engaging the threaded connection with the two sets of fixing plates 40, the two sets of fixing plates 40 can be driven to move further away from each other, thereby inserting the multiple sets of fixing shafts 401 into the currently engaged fixing holes 11 and fixing the base 10. This makes it easy to adjust the position of the base 10 along the length of the frame 1 to adjust the distance between the seat 20 and the steering handle 2, which is convenient for adjustment according to different drivers and has high driving adaptability.

[0041] During a turn, the steering handle 2 rotates, driving the second shaft 501 to rotate in the opposite direction relative to the steering handle 2 through the meshing of the fourth bevel gear 505 and the third bevel gear 504. The rotation of the first shaft 50 then drives the seat 20 to rotate in the opposite direction relative to the first shaft 50 through the meshing of the first bevel gear 502 and the second bevel gear 503. This makes it easy to drive the seat 20 to rotate in the same direction as the steering handle 2, and the seat 20 can reduce the twisting of the driver's waist by rotating the driver's body, thus avoiding muscle strain.

[0042] Furthermore, as the seat 20 rotates, it drives the two sets of protective plates 30 and the connecting rod 301 to rotate. The rotation of the connecting rod 301 causes the guide rod 302 to slide along one side of the V-shaped guide groove 303, which in turn moves the connecting rod 301. The movement of the connecting rod 301 causes the two sets of protective plates 30 to move and extend out of the back panel 201. At this time, the two sets of protective plates 30 can abut against the sides of the driver's body, which helps to keep the driver's body in place during cornering and prevents the body from shifting due to centrifugal force, thus improving driving safety and handling stability. When the seat 20 returns to center, the guide rod 302 slides in the opposite direction along one side of the V-shaped guide groove 303, causing the connecting rod 301 to move in the opposite direction. The reverse movement of the connecting rod 301 causes the two sets of protective plates 30 to move in the opposite direction and retract into the back panel 201, thereby canceling the abutment against the sides of the driver's body and ensuring the driver's body flexibility during straight-line driving.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
