Description

Technical Field

[0001] This utility model relates to the field of shock absorption technology, and in particular to a four-post shock absorber for vehicles. Background Technology

[0002] With the rapid development of e-commerce, express delivery and agriculture, the demand for goods transportation by electric tricycles is increasing. At present, most traditional electric tricycles on the market use traditional front shock absorption structures. This shock absorption structure uses a single spring, which is simple, lacks novelty and has poor effect. In order to address the above problems, we propose a vehicle four-post shock absorber. Utility Model Content

[0003] To address the problems in the prior art, we propose a four-post shock absorber for vehicles. By using four sets of shock-absorbing mechanisms, it can meet the needs of carrying heavy goods in short-distance delivery, improve transportation efficiency, and ensure good stability of the vehicle even under complex road conditions.

[0004] This utility model provides a four-post shock absorber for vehicles, including an upper cover plate and a lower connecting plate. A shock-absorbing mechanism is connected to the lower connecting plate, and the upper end of the shock-absorbing mechanism passes through the lower connecting plate and is fixed to the bottom of the upper cover plate. The damping mechanism consists of four sets, which are arranged in a rectangular pattern, with adjacent damping mechanisms being fixedly connected.

[0005] A further improvement of this utility model is that the shock absorption mechanism includes an elastic telescopic mechanism, an aluminum cylinder, and an outer spring; The fixed end of the elastic telescopic mechanism is located on the lower connecting plate and fixed to the bottom of the upper cover plate. The aluminum cylinder is sealed and movably sleeved on the fixed end of the elastic telescopic mechanism. The extended end of the elastic telescopic mechanism is connected to the inside of the aluminum cylinder. The outer spring is sleeved on the surface of the fixed end of the elastic telescopic mechanism, and both ends are connected to the fixed end of the elastic telescopic mechanism and the upper end face of the aluminum cylinder, respectively.

[0006] A further improvement of this utility model is that the elastic telescopic mechanism includes a handle, a piston rod, and a buffer spring; The handle is located on the lower connecting plate and fixed to the bottom of the upper cover plate. The piston rod is piston-type connected to the inside of the handle and extends from its lower end face to the outside of the handle. The buffer spring is located inside the handle and sleeved on the surface of the piston rod. The two ends of the buffer spring are connected to the handle and the piston rod respectively.

[0007] In a further improvement of this utility model, the upper cover plate is connected to the handle by bolts, and the piston rod is connected to the aluminum cylinder by hexagonal bolts.

[0008] A further improvement of this utility model is that two adjacent aluminum cylinders are fixedly connected.

[0009] The beneficial effects of this utility model: This utility model provides a four-post shock absorber for vehicles: First, the four sets of shock absorption mechanisms can meet the needs of carrying heavy goods in short-distance delivery, improve transportation efficiency, and ensure good stability of the vehicle even in more complex road conditions. Second, through the coordinated work of two sets of external springs and buffer springs (each set contains two springs in series), the impact forces in multiple directions such as vertical and lateral are effectively dispersed, improving the overall shock absorption and stability. Third, the low resonance frequency characteristics of the spring can absorb low-frequency vibrations, reduce vehicle body bumps, and enhance driving stability. Fourth, it adapts to the needs of unloaded, fully loaded or complex road conditions through four sets of shock absorption mechanisms; Attached Figure Description

A steering column 12 is connected to the upper cover plate 1, and a shock-absorbing mechanism 3 is connected to the lower connecting plate 2. The upper end of the shock-absorbing mechanism 3 passes through the lower connecting plate 2 and is fixed to the bottom of the upper cover plate 1. There are four sets of shock-absorbing mechanisms 3, which are arranged in a rectangular manner, and adjacent shock-absorbing mechanisms 3 are fixedly connected.

[0015] The shock absorption mechanism 3 includes an elastic telescopic mechanism 4, an aluminum cylinder 5, and an outer spring 6. The fixed end of the elastic telescopic mechanism 4 is located on the lower connecting plate 2 and is fixedly connected to the bottom of the upper cover plate 1. The aluminum cylinder 5 is sealed and movably sleeved on the fixed end of the elastic telescopic mechanism 4, and two adjacent aluminum cylinders 5 are fixedly connected.

[0016] The extended end of the elastic telescopic mechanism 4 is connected to the inside of the aluminum cylinder 5, and the outer spring 6 is sleeved on the surface of the fixed end of the elastic telescopic mechanism 4, with both ends connected to the fixed end of the elastic telescopic mechanism 4 and the upper end face of the aluminum cylinder 5, respectively.

[0017] The elastic telescopic mechanism 4 includes a handle 7, a piston rod 8, and a buffer spring 9. The handle 7 is located on the lower connecting plate 2, and the upper cover plate 1 is connected to the handle 7 by bolts 10. The piston rod 8 is piston-type connected to the inside of the handle 7 and extends from its lower end face to the outside of the handle 7.

The two ends of the buffer spring 9 are connected to the handle 7 and the piston rod 8, respectively.

[0018] The working principle of this utility model: A buffer spring 9 is fitted onto the surface of the piston rod 8.

The piston rod 8 extends from below the handle 7 and is fixed to the aluminum cylinder 5 by hexagonal bolts 11. An outer spring 6 is fitted onto the handle 7. The handle 7 is fixedly passed through the lower connecting plate 2 and fixedly connected to the lower end of the upper cover plate 1 by bolts 10, thus completing the assembly. The device is then assembled onto the front riser tube of the vehicle frame via the steering column 12 and two bearings to achieve a shock absorption effect.

[0019] This device consists of two sets of parallel buffer springs and outer springs. Each set contains two buffer springs and outer springs. These springs and springs work in conjunction with the piston rod and handle to form a complete shock absorption system. When the vehicle encounters bumps, the buffer springs and outer springs store impact energy through compression or stretching. The four buffer springs and outer springs deform collaboratively according to the direction of force, dispersing vertical, lateral, and other multi-directional impact forces, thus improving stability.
