Description

Technical Field

[0001] The invention belongs to the technical field of vehicles and relates to an all-terrain vehicle, in particular to a straddle-type all-terrain vehicle. Background Art

[0002] An all-terrain vehicle is a vehicle that can travel on any terrain. It can move freely on terrain where ordinary vehicles are difficult to maneuver. It can carry people or transport goods. It is commonly known as a beach buggy. Because its structure is very similar to that of a motorcycle and many parts are common to motorcycles, some people call it a "four-wheeled motorcycle". This type of vehicle has multiple uses and is not restricted by road conditions.

[0003] The English name of all-terrain vehicle is All Terrain Vehicle (transportation suitable for all terrains), abbreviated as ATV, commonly known as "beach car", also known as "all-terrain four-wheel off-road motorcycle". The vehicle is simple and practical, with good off-road performance. The appearance is generally canopyless. ATV has wide tires that can increase the contact area with the ground, generate greater friction and reduce the pressure of the vehicle on the ground, making it easy to travel on beaches, riverbeds, forest roads, streams, and harsh desert terrain.

[0004] After searching, it is found that Chinese patent documents disclose an all-terrain vehicle [Application No.: CN202311205232.6; Publication No.: CN117183639A]. This all-terrain vehicle includes a front shock absorber, an upper rocker arm and a lower rocker arm; the upper rocker arm is arranged above the lower rocker arm, the top end of the front shock absorber is connected to the frame, and the bottom end of the front shock absorber passes through the upper rocker arm and is connected to the lower rocker arm.

[0005] Although the all-terrain vehicle disclosed in this patent can increase the stroke of the front shock absorber and improve the shock absorption effect of the front shock absorber by passing the bottom end of the front shock absorber through the upper rocker arm and connecting it to the lower rocker arm, the camber performance of the wheel is deteriorated by connecting the lower rocker arm to the shock absorber, which affects the safety of the vehicle when turning and is prone to causing the wheel to run off track and swing, increasing the use and maintenance costs of the vehicle. In addition, the energy absorption direction is single due to the arrangement of the upper and lower shock absorbers, and the stability in the all-terrain vehicle is limited. In addition, the installation space is large and the applicability is limited. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a straddle-type all-terrain vehicle.

At the same time, by One side of the fixing plate is fixedly connected to the mounting plate, so that the triangular structure of the mounting plate drives the first adjusting plate and the second adjusting plate on one side to be installed in front of the middle frame. By symmetrically arranging the first adjusting plate and the second adjusting plate on both sides of the fixing plate, the connecting rod of the handle is installed through the inside under the action of the through hole in the middle of the fixing plate, so that the second shock absorber can shock-absorb and buffer the first adjusting plate and the second adjusting plate, thereby realizing the effective horizontal buffering of the handle by the fixing plate through the handle connecting rod, ensuring the stability and accuracy of the user when controlling the straddle-type all-terrain vehicle, and improving the user's operating comfort. At the same time, under the action of the telescopic rod telescopically arranged above the middle frame, the telescopic spring can absorb energy and buffer the movement of the telescopic rod between the reinforcement plate and the fixed convex ring through the setting of the telescopic spring, and the connecting plate is fixedly connected at one end of the telescopic rod, so that the telescopic rod can drive the connecting plate to move bufferingly, thereby improving the balance and weight distribution of the vehicle during the control process.

[0014] By adopting the above structure, through the setting of the first adjustment plate and the second adjustment plate, the first adjustment plate and the second adjustment plate can be rotated and adjusted on one side of the mounting plate through the mounting shaft and the connecting shaft. Under the action of the second shock absorber, the rotation adjustment between the first adjustment plate and the second adjustment plate has good support, thereby achieving the buffering effect of the first adjustment plate and the second adjustment plate on both sides during adjustment.

[0015] The fixing plate is arranged in an "M"-shaped structure, and a through hole for accommodating the handlebar connecting rod is provided inside the fixing plate, and the central axis of the fixing plate coincides with the central axis of the middle frame; The first adjusting plate and the second adjusting plate are rotatably connected to both sides of the fixing plate, and the first adjusting plate and the second adjusting plate are distributed in parallel.

[0016] By adopting the above structure, under the action of the fixed plate, the first adjustment plate and the second adjustment plate on both sides are buffered and adjusted through the second shock absorber, and in order to achieve the flexibility of the all-terrain vehicle, the second shock absorber can be arranged in an inverted "eight" and an inner "eight" shape on the surface of the first adjustment plate and the second adjustment plate, so as to meet different buffering requirements, and in order to improve the buffering effect, the second shock absorber can also be synchronously arranged at the upper and lower ends of the first adjustment plate and the second adjustment plate, ensuring the shock absorbing effect of the second shock absorber, and high flexibility and convenient adjustment.

[0028] 2. In the present invention, by arranging a stabilizing component above the middle frame, under the action of the telescopic spring sleeved on the outer wall of the telescopic rod, when the telescopic rod is telescopically moved inside the reinforcement plate, the telescopic spring absorbs energy and buffers the movement of the telescopic rod between the reinforcement plate and the fixed convex ring, thereby achieving synchronous energy absorption of the front and rear wheels in the middle of the vehicle, ensuring the stability of the center of gravity of the vehicle, avoiding the rearward or forward shifting of the center of gravity of the straddle-type all-terrain vehicle when traveling on different terrains, and effectively preventing the straddle-type all-terrain vehicle from tipping over when traveling on uneven ground.

[0030] 4. In the present invention, by arranging a self-adjusting component on the surface of the connecting plate and arranging a compression spring, the saddle can be raised and lowered by the "X"-shaped structure of the first movable plate when the user sits on it, and by fixing the electromagnetic block on the surface of the connecting plate under the action of magnetism of the lower mounting block, when the user is lighter, the electromagnetic block can release the magnetism by energizing, so that the lower mounting block drives the saddle to the adaptive position through the first movable plate. At the same time, under the action of the electromagnetic block, the electromagnetic block limits the moving position of the lower mounting block on the outside, thereby avoiding the problem of the saddle being too low due to the excessive weight on the surface of the saddle, and ensuring the adaptive effect of the saddle.

Specifically, the stabilizing component includes two reinforcing plates 32, both of which are fixedly mounted on the outer wall of the middle frame 7. By connecting the reinforcing plates 32 to the main frame 1, the main frame 1 and the middle frame 7 maintain a stable structure, thereby ensuring the overall stability of the straddle-type all-terrain vehicle. The two reinforcing plates 32 are aligned with the central axis of the connecting plate 34. The reinforcing plate 32 is provided with an axial hole for accommodating the transmission shaft. With the axial hole provided in the middle of the reinforcing plate 32, the transmission shaft can be rotatably installed in the middle of the reinforcing plate 32, thereby realizing the synchronous driving of the front and rear wheels of the all-terrain vehicle, ensuring the driving effect of the all-terrain vehicle, and having a compact structure, realizing the rational use of the space in the middle of the vehicle. At the same time, in order to improve the stability of the middle of the vehicle, telescopic rods 33 are provided through the insides of the two reinforcing plates 32, and the telescopic rods 33 are located above the middle frame 7, and telescopic springs 35 are fixedly connected to the outer walls of the two sides of the reinforcing plate 32, and the telescopic springs 35 are sleeved on the outer walls of the telescopic rods 33, and the outer walls of the telescopic rods 33 are fixedly connected with fixed convex rings for limiting the telescopic springs 35. With such an arrangement, when the telescopic rod 33 is telescopically movable inside the reinforcement plate 32, the telescopic spring 35 between the reinforcement plate 32 and the fixed convex ring absorbs energy and buffers the movement of the telescopic rod 33. At the same time, considering the connection of the other end of the telescopic rod 33, a through hole 36 is provided at the end of the telescopic rod 33 away from the telescopic spring 35, and the telescopic rod 33 is fixedly connected to the main frame 1 through the through hole 36, so that the stabilizing component and the main frame 1 can be stably installed, and a connecting plate 34 is fixedly installed between the two telescopic rods 33, and the surface of the connecting plate 34 has a saddle 6 mounting frame through a self-adjusting component, so that the saddle 6 can be adaptively adjusted to the user, wherein the self-adjusting component includes a side plate 37, and the side plate 37 is fixedly connected to the bottom end of the saddle 6,Two upper mounting blocks 38 are slidably connected to the lower part of the side plate 37.

Moreover, under the action of the compression spring 42, the user can sit on the saddle 6 and adjust the lifting and lowering through the "X"-shaped structure of the first movable plate 39. Moreover, under the action of the magnetism of the lower mounting block 41, the electromagnetic block 43 is fixedly installed on the surface of the connecting plate 34. Therefore, when the user is lighter, the electromagnetic block 43 can release the magnetism by powering on, so that the lower mounting block 41 drives the saddle 6 through the first movable plate 39 until it is adaptive. Moreover, through the fixed setting of the electromagnetic block 43, the electromagnetic block 43 limits the position of the lower mounting block 41 on the outside, avoiding the problem of the saddle 6 being too low due to the excessive weight on the surface of the saddle 6, thereby ensuring the adaptive effect of the saddle 6.

By setting the first adjusting plate 23 and the second adjusting plate 25, the first adjusting plate 23 and the second adjusting plate 25 can be rotatably adjusted on one side of the mounting plate 20 through the mounting shaft and the connecting shaft, and a second shock absorber 26 is installed on the surfaces of the first adjusting plate 23 and the second adjusting plate 25, and the two ends of the second shock absorber 26 are fixedly connected to the first adjusting plate 23 and the second adjusting plate 25 respectively. Under the action of the second shock absorber 26, the first adjusting plate 23 and the second adjusting plate 25 are The rotation adjustment between the two adjustment plates 25 has good support, and the buffering effect of the first adjustment plates 23 and the second adjustment plates 25 on both sides during adjustment is realized. Through such a setting, under the action of the fixed plate 29, the first adjustment plates 23 and the second adjustment plates 25 on both sides are buffered and adjusted through the second shock absorber 26. At the same time, the first adjustment plate 23 and the second adjustment plate 25 are rotatably connected on both sides of the fixed plate 29, and the first adjustment plate 23 and the second adjustment plate 25 are distributed in parallel. The fixed plate 29 is arranged in an "M"-shaped structure, and a through hole for accommodating the handle 4 connecting rod is opened inside the fixed plate 29, and the central axis of the fixed plate 29 coincides with the central axis of the middle frame 7. Under the action of the through hole opened inside the fixed plate 29, the fixed plate 29 can effectively buffer the handle 4 horizontally through the handle 4 connecting rod, ensuring the stability and accuracy of the user when controlling the straddle-type all-terrain vehicle, and the fixed plate 29 is arranged to coincide with the central axis of the middle frame 7, so as to achieve the stability of the vehicle driving and improve the comfort and balance of the user's riding.

[0035] The working principle of the present invention is as follows: when in use, a walking wheel 5 is installed at the outer end of a steering knuckle 16, so that the straddle-type all-terrain vehicle can travel. When turning, the handle 4 is connected to the adjusting link 12, and the adjusting link 12 connects the upper rocker arm 14 and the lower rocker arm 13, so that the user can synchronously control the steering of the all-terrain vehicle. Moreover, by adding the adjusting link 12 to the lower rocker arm 13, the steering arm 15 has a larger adjustable angle, thereby improving the steering effect of the vehicle. Moreover, by fixing the adjusting link 12 on the fixed sleeve 9, the fixing sleeve 9 is inclined at one side. Under the action of the inverted installation of the first shock absorber 11, the first shock absorber 11 can effectively absorb the shock of the vehicle in the depth direction, effectively absorb the multi-directional vibration energy generated on the uneven ground, and ensure the safety of the movement of the walking wheel 5. At the same time, under the inverted action of the first shock absorber 11, the support strength of the vehicle is improved, and the installation space of the vehicle is saved, which can effectively avoid rollover and shaking, and extend the service life of the first shock absorber 11. At the same time, by fixing the mounting plate 20 on one side of the multi-directional connecting seat 19, the triangular structure of the mounting plate 20 drives one side The first adjustment plate 23 and the second adjustment plate 25 are installed in front of the middle frame 7. By symmetrically arranging the first adjustment plate 23 and the second adjustment plate 25 on both sides of the fixing plate 29, the connecting rod of the handle 4 is installed through the fixing plate 29 through the middle of the fixing plate 29, so that the second shock absorber 26 can buffer the first adjustment plate 23 and the second adjustment plate 25, and the fixing plate 29 can effectively buffer the handle 4 horizontally through the connecting rod of the handle 4, thereby ensuring the stability and accuracy of the user when controlling the straddle-type all-terrain vehicle and improving the user's operating comfort. At the same time, under the action of the telescopic rod 33 telescopically arranged above the middle frame 7, the telescopic spring 35 is arranged, so that the telescopic spring 35 can absorb energy and buffer the movement of the telescopic rod 33 between the reinforcement plate 32 and the fixed convex ring, and the connecting plate 34 is fixedly connected at one end of the telescopic rod 33, so that the telescopic rod 33 can drive the connecting plate 34 to move bufferingly, thereby improving the balance and weight distribution of the vehicle during the control process, and preventing the problem of the center of gravity of the straddle-type all-terrain vehicle moving backward or forward when traveling on different terrains, thereby completing the working principle of the straddle-type all-terrain vehicle.

[0036] In summary, in the present invention, the installation position and installation angle of the first shock absorber 11 are changed by the setting of the shock absorbing assembly, thereby improving the space utilization rate of the bottom of the vehicle, and by obliquely setting the first shock absorber 11, the shock absorbing effect on the vehicle in the depth direction is achieved. Compared with the existing up and down shock absorption, the shock absorption direction is more directional, which can effectively absorb the multi-directional vibration energy generated on the uneven ground, and improve the stability and comfort of the vehicle. In addition, by adding an adjusting link 12 between the upper rocker arm 14 and the lower rocker arm 13, the steering arm 15 has a larger adjustable angle, which improves the steering flexibility of the all-terrain vehicle, facilitates the user to operate the vehicle stably and accurately, and solves the technical problems of the current all-terrain vehicle's poor roll and suspension stability and the inability to perform stable multi-directional shock absorption and buffering on the straddle-type all-terrain vehicle.
