Description

Technical Field

[0001] This utility model relates to the field of beach buggy technology, specifically to a beach buggy rear axle assembly with a buffer mechanism. Background Technology

[0002] ATV, short for All-Terrain Vehicle, is a common name for a vehicle suitable for all terrains. Its formal name is "All-Terrain Vehicle." ATVs can travel on any terrain, moving freely in places where ordinary vehicles struggle. They are simple, practical, and have excellent off-road capabilities. High-quality, high-performance ATVs can easily traverse beaches, riverbeds, forest trails, streams, and even the harshest deserts. Whether carrying people or transporting goods, the ATV's functionality is fully utilized, making it a truly versatile mobility tool.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 213007471 U), "This utility model provides a rear axle suspension assembly for a beach buggy, belonging to the field of beach buggy technology. It solves the problem that existing beach buggies tilt when traveling on uneven roads, causing swaying for the driver and affecting the riding experience. This utility model includes a rear axle, a cantilever shock absorber, and a connecting frame. One end of the connecting frame is movably connected to the frame of the beach buggy, and the other end is movably connected to the rear axle via a first rotating shaft. The first rotating shaft is perpendicular to the rear wheel axle centerline of the beach buggy, allowing the rear axle to rotate and yaw around the axis of the first rotating shaft. The cantilever shock absorber connects the frame and the rear axle, providing suspension support and shock absorption for the rear axle. The advantage of this utility model is that it allows the rear axle to rotate and yaw around the axis of the first rotating shaft, combined with the cantilever shock absorber. Furthermore, shock absorbers are provided at multiple connection points between the rear axle and the frame, enhancing the shock absorption and cushioning effect of the vehicle body."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this utility model allows the rear axle to rotate and yaw around the axis of the first pivot, combined with a cantilevered shock absorber. Furthermore, multiple connection points between the rear axle, frame, and suspension are equipped with shock absorbers. Through the coordinated use of these structures, the shock absorption and cushioning effect of the vehicle body can be maximized. However, in actual use, because the shock absorption coefficient of this device is fixed, it cannot adequately meet the needs of different terrains and users. Additionally, due to the complex operating environment, the wiring harness is prone to loosening under bumpy conditions. Therefore, it is necessary to improve the ATV rear axle assembly by incorporating a cushioning mechanism to solve these problems. Utility Model Content

[0031] Furthermore, the adjustable buffer assembly 61 includes a first fixed block 611, which is fixedly connected to the top of the first bracket 1. A first rotating block 612 is rotatably connected inside the first fixed block 611. A second fixed block 613 is fixedly connected to the right side of the second bracket 2. A second rotating block 614 is rotatably connected inside the second fixed block 613. An adjusting platform 615 is fixedly connected to the right side of the second rotating block 614. A first threaded rod 619 is rotatably connected inside the adjusting platform 615. A first limiting rod 6110 is fixedly connected inside the adjusting platform 615. A movable block 616 is slidably connected to the outside of the first limiting rod 6110. A damping rod 617 is fixedly connected to the right side of the movable block 616. A shock-absorbing spring 618 is fixedly connected to the right side of the movable block 616. This facilitates the damping of vibrations occurring during the use of the ATV while simultaneously adjusting the damping coefficients of the damping rod 617 and the shock-absorbing spring 618.

[0032] Furthermore, the damping rod 617 is fixedly connected to the first rotating block 612, the shock-absorbing spring 618 is fixedly connected to the first rotating block 612, the movable block 616 is threadedly connected to the first threaded rod 619, and the movable block 616 is slidably connected to the adjusting table 615, which facilitates a more stable shock absorption process.

[0033] Furthermore, the protective component 62 includes a connecting platform 621, which is fixedly connected to the top of the second bracket 2. A bidirectional threaded rod 624 is rotatably connected inside the connecting platform 621. A second limiting rod 625 is fixedly connected inside the connecting platform 621. A movable plate 622 is slidably connected to the outside of the second limiting rod 625.

[0034] Furthermore, the movable plate 622 is threadedly connected to the bidirectional threaded rod 624, and the connecting platform 621 is provided with a groove at the corresponding position of the movable plate 622, and the movable plate 622 is slidably connected inside the groove, which facilitates a more stable limiting process. Example

[0035] Please see Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary transmission mechanism 7 includes a connecting block 71, which is fixedly connected to the bottom of the second bracket 2. A connecting box 72 is fixedly connected to the front of the connecting block 71. A second spring 75 is fixedly connected inside the connecting box 72. A movable frame 73 is fixedly connected to the top of the second spring 75. A connecting roller 74 is rotatably connected inside the movable frame 73, which facilitates the connection roller 74 to always be in contact with the chain, thus avoiding the chain from becoming loose due to excessive amplitude during use.

[0036] Furthermore, grooves are provided at corresponding positions of the connecting box 72 and the movable frame 73, and the movable frame 73 is slidably connected inside the grooves. The connecting roller 74 is in contact with the chain drive device 4, which facilitates more stable use.

[0037] In actual operation, when this device is used, the user first adjusts it according to their needs. The user rotates the first threaded rod 619. The rotation of the first threaded rod 619, in conjunction with the first limit rod 6110, causes the movable block 616 to move, thereby compressing and releasing the damping rod 617 and the shock-absorbing spring 618. When vibration occurs during the use of the ATV, the first support 1 and the second support 2 rotate, causing the first fixed block 611 and the second fixed block 613 to move. This, in turn, causes the first rotating block 612 and the second rotating block 614 to rotate, which, in conjunction with the damping rod 617 and the shock-absorbing spring 618, damping the vibration between the first support 1 and the second support 2. After the section is completed, the user constrains the relevant connecting harnesses of the rear axle assembly, such as brake cables, and passes the connecting harnesses between the connecting platform 621 and the limiting block 623. The user rotates the bidirectional threaded rod 624. The rotation of the bidirectional threaded rod 624, in conjunction with the second limiting rod 625, causes the movable plate 622 to move, thereby causing the limiting block 623 to move. After the constraint is completed, the engine 5 is turned on, and in conjunction with the chain drive device 4, the rear wheel 3 of the ATV rotates, realizing the transmission of the device. The chain drive device 4 drives the connecting roller 74 to move. The movement of the connecting roller 74, in conjunction with the second spring 75, causes the movable frame 73 to slide inside the connecting box 72.
