Description
A type of beach buggy shock absorption mechanism Technical Field
[0001] This utility model relates to the technical field of beach buggy suspension systems, specifically a beach buggy shock absorption mechanism. Background Technology
[0002] Currently, conventional ATV suspension systems mainly suffer from the following technical defects:
[0003] 1. Limitations of single swing arm structure: Traditional single swing arm design is prone to stress concentration on rough roads, leading to fatigue fracture of connecting parts and causing severe vehicle bumps, making it difficult to maintain stable driving.
[0004] 2. Insufficient shock absorption performance: Most existing shock absorbers adopt a unidirectional force-bearing design, which has a poor absorption effect on tilting impact force, and the body roll angle often exceeds the safety threshold.
[0005] 3. Inconvenient maintenance: The integral connection structure means that replacing the shock absorber components requires disassembling the entire suspension system, with an average repair time of 2-3 hours.
[0006] To address this, those skilled in the art have proposed a shock-absorbing and swaying mechanism for beach buggies. Summary of the Invention
[0007] To address the shortcomings of existing technologies, this utility model proposes a shock-absorbing and swaying mechanism for ATVs, which uses a double swing arm connection structure to form a stable motion trajectory, thereby achieving dynamic adjustment and stability control of the vehicle body under complex road conditions.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A beach buggy shock absorption mechanism includes a wheel assembly connector, an upper swing arm, a lower swing arm, a wheel connector, and a shock absorption assembly. The upper swing arm and the lower swing arm are movably connected to the left and right sides of the wheel assembly connector, respectively. The wheel connector is movably connected to the ends of the upper and lower swing arms away from the wheel assembly connector. The shock absorption assembly is movably connected between the wheel assembly connector and the lower swing arm.
[0010] Furthermore, the wheel assembly connecting body is provided with a mounting groove, and a fixing hole is provided on the opposite inner side of the mounting groove. The first end of the upper and lower swing arm components that connects to the wheel assembly connecting body is provided with a through hole corresponding to the fixing hole.

[0011] Furthermore, the upper and lower ends of the wheel connector are provided with fixing holes two, and the second ends of the upper and lower swing arm and the wheel connector are provided with through holes two corresponding to fixing holes two. A connecting pin is inserted between the through hole two and the fixing hole two.
[0012] Furthermore, the shock absorption assembly is a spring shock absorption assembly, including a rod and a compression spring; the rod has connecting parts with through holes at both ends, and the compression spring is sleeved on the outside of the rod, with its two ends respectively abutting against the flange of the rod.
[0013] Furthermore, the wheel assembly connecting body is provided with a second mounting groove, and a second fixing hole corresponding to the third through hole is provided on the opposite inner side of the second mounting groove.

[0015] Compared with existing technologies, this invention offers the following advantages: It provides a beach buggy shock absorption mechanism, including a wheel assembly connector, an upper swing arm, a lower swing arm, a wheel connector, and a shock absorber assembly. The upper and lower swing arms are movably connected to the left and right sides of the wheel assembly connector, respectively. Wheel connectors are movably connected to the ends of the upper and lower swing arms away from the wheel assembly connector.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please refer to Figures 1-6. This utility model provides a technical solution: a beach buggy shock absorption mechanism, including a wheel assembly connector 1, an upper swing arm 2A, a lower swing arm 2B, a wheel connector 3, and a shock absorption assembly 4. The upper swing arm 2A and lower swing arm 2B are movably connected to the left and right sides of the wheel assembly connector 1, respectively. The wheel connector 3 is movably connected to the ends of the upper swing arm 2A and lower swing arm 2B away from the wheel assembly connector 1. The shock absorption assembly 4 is movably connected between the wheel assembly connector 1 and the lower swing arm 2B. The wheel is connected to the wheel connector 3 via a connecting shaft 5. This beach buggy shock absorption mechanism adopts a double swing arm connection structure. Through the synergistic action of the upper swing arm 2A and lower swing arm 2B, a stable motion trajectory is formed, achieving dynamic adjustment and stability control of the vehicle body under complex road conditions, overcoming the rigid connection structure used in existing technologies. The shock absorption assembly 4 directly connects the wheel assembly connector 1 and the lower swing arm 2B, effectively absorbing vertical and tilting impacts, further improving vehicle stability and reducing the risk of vehicle roll.
[0025] Please refer to Figures 3-4. The wheel assembly connector 1 has a mounting groove 10, and a fixing hole 100 is provided on the opposite inner surface of the mounting groove 10. The first end of the upper swing arm 2A and the lower swing arm 2B that connects to the wheel assembly connector 1 has a through hole 20 corresponding to the fixing hole 100. A connecting pin passes through the fixing hole 100 and the through hole 20. Through the cooperative design of the connecting pin, the mounting groove 10, and the fixing hole 100, a movable connection point is formed for the upper and lower swing arms to rotate and connect with the wheel assembly connector 1. The movable connection point disperses stress, reduces vehicle body sway under bumpy road conditions, and improves dynamic stability under complex road conditions. It should be noted that after the connecting pin passes through the fixing hole 100 and the through hole 20 in sequence, a nut is provided at the end of the connecting pin to prevent the swing arm from moving. Nuts are also provided for the same structure in the following sections.
[0026] Please refer to Figures 4-5. The upper and lower sides of the wheel connector 3 are provided with fixing holes 30. The second ends of the upper swing arm 2A and lower swing arm 2B, which connect to the wheel connector 3, are provided with through holes 21 corresponding to the fixing holes 30. A connecting pin passes through the through hole 21 and the fixing hole 30. Through the coordinated design of the connecting pin, fixing holes 30, and through holes 21, a movable connection point is formed between the upper and lower swing arm components and the wheel connector 3. This movable connection point disperses stress, reduces vehicle body sway under bumpy road conditions, and improves dynamic stability under complex road conditions.
[0027] Please refer to Figure 6. The shock absorber assembly 4 is a spring shock absorber assembly, including a rod 40 and a compression spring 41. The rod 40 has connecting parts 400 with through holes 401 at both ends. The compression spring 41 is sleeved on the outside of the rod, and its two ends abut against the flanges 402 of the rod. The shock absorber assembly 4 directly connects the wheel assembly connector 1 and the lower control arm 2B, effectively absorbing vertical and tilting impact forces, further improving vehicle stability and reducing the risk of vehicle roll.
[0028] Please refer to Figures 3-4 and 6. The wheel assembly connector 1 has a mounting groove 21. The inner surface of the mounting groove 21 has a fixing hole 210 corresponding to the through hole 301. A connecting pin passes through the fixing hole 210 and the through hole 301. Through the coordinated design of the connecting pin, fixing hole 210, and through hole 301, a movable connection point is formed between the rod 40 and the wheel assembly connector 1 for rotatable connection. The lower control arm 2B has a mounting groove 322. The inner surface of the mounting groove 322 has a fixing hole 320 corresponding to the through hole 301. A connecting pin passes through the fixing hole 320 and the through hole 301. Through the design of the connecting pin, fixing hole 322, and through hole 301, a movable connection point is formed between the rod 40 and the lower control arm 2B for rotatable connection. Since the rod 40 forms movable connection points with the wheel assembly connector 1 and the wheel connector 3, it can achieve synchronous absorption of vertical / tilted impact forces; and it allows the shock absorption assembly 4 to be quickly disassembled and assembled with the lower control arm 2B and the wheel assembly connector 1, which is convenient for maintenance or replacement of parts.
[0029] This ATV's shock absorption mechanism employs a double-swing arm connection structure. When the wheels are impacted by the road surface, the upper and lower swing arms rotate around the connecting pin. Through the coordinated action of the upper swing arm 2A and the lower swing arm 2B, a stable motion trajectory is formed, achieving dynamic adjustment and stability control of the vehicle body under complex road conditions, overcoming the limitations of existing technologies that use rigid connection structures. The shock absorption assembly 4 directly connects the wheel assembly connector 1 and the lower swing arm 2B, effectively absorbing vertical and tilting impact forces, further improving vehicle stability and reducing the risk of vehicle roll.
