Description

Technical Field

[0001] This utility model relates to the field of auxiliary components for electric off-road vehicles, specifically to an electric off-road vehicle with a seat rocking function. Background Technology

[0002] Electric off-road vehicles, as a type of electric-powered special vehicle, are widely used in harsh terrain environments such as sand, mud, riverbanks, mountains, and even rocky areas due to their strong power and good passability.

[0003] Currently, most mainstream electric off-road vehicles on the market use a rigid fixed connection between the seat and the frame. However, this connection structure has significant drawbacks in actual driving: when the vehicle is driving on a slope with a large angle, the fixed seat cannot adaptively adjust according to the road inclination angle, causing the vehicle's center of gravity to easily shift; in scenarios where the vehicle is making sharp turns at high speeds, a large centrifugal force is generated, further aggravating the instability of the vehicle's center of gravity, which can easily cause the vehicle to lose balance or even roll over, causing serious damage to the electric off-road vehicle itself and posing a significant threat to the life safety of the driver. Utility Model Content

[0004] The purpose of this utility model is to provide an electric off-road vehicle with a seat rocking function in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides an electric off-road vehicle with a seat rocking function, including a vehicle frame and a seat frame. The seat frame is located on top of the vehicle frame, and the front and rear positions of the seat frame are fixedly combined with the vehicle frame by rotating supports, so as to enable the seat frame to swing left and right to overcome centrifugal force by means of the rotating supports.

[0007] Preferably, the rotating support member at the front of the seat frame and the vehicle frame is specifically configured such that a support arm is fixedly arranged at the front of the vehicle frame, and a bearing seat is fixedly installed on the top of the support arm; a bracket is fixedly arranged at the front of the seat frame, and the support arm is located between the front and rear positions of the bracket; a shaft is longitudinally inserted and fixed at the top of the bracket, and the shaft passes through the bearing seat coaxially and is fixedly coaxially with the inner ring of the slewing bearing built into the bearing seat.

[0008] Preferably, the rotating support at the rear of the seat frame and the vehicle frame is specifically configured such that a support arm is fixedly arranged at the rear of the vehicle frame, and a bearing seat is fixedly installed at the top of the support arm; a support connecting seat is fixedly arranged at the rear of the seat frame; a shaft is fixedly arranged on the support connecting seat extending longitudinally rearward; and the shaft passes through the bearing seat coaxially and is fixedly coaxially with the inner ring of the slewing bearing built into the bearing seat.

[0009] Preferably, the support arms are all V-shaped support structures with inverted tops and flat surfaces.

[0010] Preferably, a swing limiting rod is longitudinally inserted and fixed at the middle position of the bottom of the bracket at the front position, so as to limit the extreme swing angle by the swing limiting rod contacting and abutting against the inner side of the support arm when the bracket swings with the shaft.

[0011] Preferably, the swing limiting rod is fixed to the bracket by first inserting and then welding, and the swing limiting rod is coaxially covered and fixed with a nitrile rubber sleeve with a Shore hardness of 60-70 on its outer periphery between the front and rear of the bracket.

[0012] Preferably, the left and right swing angle range of the seat frame around the axis of the shaft is ±15°.

[0013] Preferably, the bearing housing uses a deep groove ball bearing, and the inner ring of the bearing housing is interference-fitted with the shaft, while the outer ring is interference-fitted with the inner hole of the bearing housing.

[0014] Preferably, the shaft is fixed to the bracket and the support connecting seat by welding, and the axis of the shaft at the front and rear positions is on the same horizontal straight line.

[0015] Preferably, the seat frame is integrally formed from high-strength aluminum alloy, and the support connecting seat is welded and fixed to the seat frame.

[0016] In the aforementioned electric off-road vehicle with a seat rocking function, during real-time use, the seat frame is fixedly integrated with the front and rear of the vehicle frame via rotating support members. This allows the seat frame to rock left and right. When the vehicle is traveling on a slope, the axle rotates around the bearing seat, causing the seat frame to automatically rock. This allows the seat frame to adjust its posture according to the road inclination angle, maintaining the driver in a level seating position and effectively preventing the vehicle's center of gravity from shifting due to road inclination, thus improving the vehicle's performance on slopes. The system improves road surface stability and, during high-speed sharp turns, the seat frame automatically swings by rotating the axle around the bearing seat. This swinging motion of the seat frame counteracts some of the centrifugal force, reducing the driver's sense of tilt caused by centrifugal force and ensuring a smooth and comfortable turning process. It also prevents the vehicle from overturning due to excessive centrifugal force. Furthermore, the rotating support component has a simple and compact structure, and its components are easy to process and assemble, resulting in low manufacturing costs and convenient maintenance. It is suitable for mass production and can effectively improve the driving safety and comfort of electric off-road vehicles.

[0017] The beneficial effects are as follows: 1. The seat frame of this utility model is fixedly combined with the front and rear positions of the vehicle frame by rotating support members, which enables the seat frame to have the function of swinging left and right. When the vehicle is driving on a slope, the seat frame can be automatically swayed by rotating the axle around the bearing seat. This allows the seat frame to adjust its posture according to the slope angle of the road, always keeping the driver in a horizontal sitting position, effectively preventing the vehicle's center of gravity from shifting due to the slope, and improving the stability of the vehicle when driving on a slope.

[0018] 2. When the vehicle makes a high-speed sharp turn, the seat frame automatically swings by rotating the axle around the bearing seat. The left and right swing of the seat frame can counteract some of the centrifugal force, reduce the tilting sensation caused by centrifugal force, ensure a smooth and comfortable turning process, and prevent the vehicle from overturning due to excessive centrifugal force.

[0019] 3. The rotating support has a simple and compact structural design, and each component is easy to process and assemble, resulting in low manufacturing costs. It is also easy to maintain in the later stages, making it suitable for large-scale mass production applications and effectively improving the driving safety and comfort of electric off-road vehicles.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] See Figures 1-10 As shown, this utility model provides an electric off-road vehicle with a seat rocking function, including a frame body 2 and a seat frame 1. The seat frame 1 is located on top of the frame body 2, and the front and rear positions of the seat frame 1 and the frame body 2 are fixedly combined by rotating support members 3, which are used to enable the seat frame 1 to swing left and right to overcome centrifugal force. Specifically, the rotating support member 3 at the front position of the seat frame 1 and the frame body 2 is as follows: a support arm 301 is fixedly configured at the front position of the frame body 2, and a bearing seat 302 is fixedly installed on the top of the support arm 301; a bracket 305 is fixedly configured at the front of the seat frame 1, and the support arm 301 is located between the front and rear positions of the bracket 305; a shaft 3 is longitudinally inserted and fixed at the top of the bracket 305. 03, and the shaft 303 passes through the bearing seat 302 coaxially and is fixed coaxially with the inner ring of the slewing bearing built into the bearing seat 302. Specifically, the rotating support 3 at the rear of the seat frame 1 and the vehicle frame 2 is configured as follows: the rear of the vehicle frame 2 is fixedly equipped with a support arm 301, and the top of the support arm 301 is fixedly installed with a bearing seat 302. The rear of the seat frame 1 is fixedly equipped with a support connecting seat 306, and the support connecting seat 306 extends longitudinally backward and is fixedly equipped with a shaft 303. The shaft 303 passes through the bearing seat 302 coaxially and is fixed coaxially with the inner ring of the slewing bearing built into the bearing seat 302. The purpose of this arrangement is that the seat frame 1 can be automatically swayed by the left and right rotation of the shaft 303 around the bearing seat 302, thereby enabling the seat frame 1 to achieve the swaying function.

[0035] See Figures 1-8As shown, the following optimizations have been made to this application. Specifically, the support arms 301 are all inverted V-shaped support structures with flat tops. This design firstly ensures good structural stability for the support arms 301 themselves, and also facilitates the secure mounting of the bearing seats 302 on the top of the support arms 301. Further optionally, a swing limiting rod 304 is longitudinally inserted and fixed at the middle of the bottom of the bracket 305 at the front position. With this configuration, when the bracket 305 swings with the shaft 303, the swing limiting rod 304 contacts and abuts against the inner side of the support arm 301 to limit the extreme swing angle. Optionally, the swing limiting rod 304 is fixed to the bracket 305 by first inserting and then welding. Furthermore, a nitrile rubber sleeve with a Shore hardness of 60-70 is coaxially wrapped and fixed around the swing limiting rod 304 between the front and rear ends of the bracket 305, so as to use the nitrile rubber sleeve to buffer and limit the swing of the seat frame 1. Furthermore, the left and right swing angle range of the seat frame 1 around the axis of the shaft 303 is ±15°, so that the swing range of the seat frame 1 is within a suitable range, avoiding excessive extreme swing angle and over-adjustment of driving posture.

[0036] See Figures 1-10 As shown, the bearing housing 302 uses a deep groove ball bearing, and the inner ring of the bearing inside the bearing housing 302 is interference-fitted with the shaft 303, while the outer ring is interference-fitted with the inner hole of the bearing housing 302. This ensures that the bearing housing 302 itself has good rotational support capability, enabling the seat body to achieve stable and repetitive automatic swinging motion. Optionally, the shaft 303 is fixed to the bracket 305 and the support connecting seat 306 by welding, and the axes of the shaft 303 at the front and rear positions are on the same horizontal straight line. This arrangement ensures that the seat body can smoothly swing to the left and right. Alternatively, the seat frame 1 is integrally formed from high-strength aluminum alloy, and the support connecting seat 306 is welded to the seat frame 1. This ensures that the seat frame 1 has a good structural stability design and that the support connecting seat 306 can be stably fixed to the rear of the seat frame 1.

[0037] With the above structure, in real-time use, since the front and rear positions of the seat frame 1 and the vehicle frame 2 are fixedly combined by rotating support members 3, the seat frame 1 can swing left and right. Therefore, when the vehicle is traveling on a slope, the left and right rotation of the axle 303 around the bearing seat 302 causes the seat frame 1 to automatically swing, allowing the seat frame 1 to adjust its posture according to the road inclination angle, always maintaining the driver in a level sitting position. This effectively prevents the vehicle's center of gravity from shifting due to road inclination, improving the vehicle's stability when driving on slopes. Meanwhile, when the vehicle makes a high-speed sharp turn, the seat frame 1 automatically swings by rotating the axle 303 around the bearing seat 302. The left and right swing of the seat frame 1 can counteract some of the centrifugal force, reduce the tilting sensation caused by centrifugal force, ensure a smooth and comfortable turning process, and prevent the vehicle from overturning due to excessive centrifugal force. Furthermore, the rotating support 3 has a simple and compact structural design, and each component is easy to process and assemble, resulting in low manufacturing costs. It is also easy to maintain in the later stages, making it suitable for large-scale mass production applications and effectively improving the driving safety and comfort of electric off-road vehicles.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
