[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. In the description of the present invention, it should be understood that, unless otherwise specified, the meaning of "multiple" is two or more.
[0034] See also Figure 1 to Figure 2A shock absorbing mechanism according to a specific embodiment of the present invention is connected to a vehicle frame and a wheel assembly 6 at the same time, so as to limit the jumping amplitude of the wheel assembly 6 when the wheel passes over a bumpy road surface. The shock absorbing mechanism includes a buffer assembly 1 and a limit assembly 2. The middle part of the buffer assembly 1 is connected to a coupling 5 of the wheel assembly 6 via a first mounting bracket 3, and both ends of the buffer assembly 1 are connected to the vehicle frame via a second mounting bracket 4. The limit assembly 2 is arranged on the buffer assembly 1 and connected to the buffer assembly 1 via the first mounting bracket 3. The buffer assembly 1 can be compressed when the wheel assembly 6 jumps, and at the same time, a downward force is applied to the wheel assembly 6, so as to limit the jumping amplitude of the wheel assembly 6. The two ends of the buffer assembly 1 will be lifted upward after being subjected to pressure. At this time, the limit assembly 2 arranged above the buffer assembly 1 can limit the upward lifting height of the two ends of the buffer assembly 1, and can also limit the jumping amplitude generated by the wheel assembly 6.
[0035] Specifically, the buffer assembly 1 includes a plurality of buffer plates 11, all of which are arc-shaped structures, and the arc lengths of the plurality of buffer plates 11 included in the arc-shaped structures gradually increase from bottom to top. In addition, the limit assembly 2 includes a plurality of limit plates 21, all of which are arc-shaped structures, and the arc lengths of the plurality of limit plates 21 in the arc-shaped structures decrease from top to bottom. It should be noted that the plurality of buffer plates 11 included in the buffer assembly 1 can be made of steel plates.
[0036] More specifically, the first mounting bracket 3 includes a mounting seat 31 and a fixing plate 32. The mounting seat 31 is arranged on the coupling 5 of the wheel assembly 6. The buffer plate 11 with the shortest arc length in the buffer assembly 1 is arranged on the mounting seat 31. The fixing plate 32 is pressed against the limiting plate 21 with the longest arc length in the limiting assembly 2.
[0037] In addition, the first mounting bracket 3 also includes a fixed connecting member 33, and a plurality of fixed mounting holes 321 are opened on the fixed plate 32. The fixed connecting members 33 are respectively arranged on both sides of the limit assembly 2 and the buffer assembly 1, and the fixed connecting members 33 are suitable for simultaneously connecting the fixed mounting holes 321 opened on the same side, so that the fixed plate 32 presses the limit assembly 2 and the buffer assembly 1 on the mounting seat 31.
[0038] The fixed connector 33 is a U-shaped member, which passes through the bottom of the coupling 5 to lift the coupling 5, and threaded sections 331 are provided at both ends of the U-shaped fixed connector 33. Therefore, the coupling 5 and the fixed plate 32 can be connected and fixed by the U-shaped fixed connector 33, and the setting of the threaded section 331 can adjust the pressure generated by the fixed plate 32 on the limit assembly 2 and the buffer assembly 1 to adjust the overall tightness.
[0039] Therefore, by making the steel plate into the above-mentioned arc-shaped structure, when the wheel assembly 6 jumps upward, the wheel assembly 6 presses the middle part of the arc-shaped buffer plate 11 through the mounting seat 31, so that the arc-shaped buffer plate 11 moves from the arc plate to the straight plate. At this time, the buffer plate 11 also generates a relative force on the wheel assembly 6, thereby limiting the upward movement of the wheel assembly 6. When the wheel assembly 6 sinks when passing through a pothole road, the wheel assembly 6 pulls down the buffer assembly 1 and the limit assembly 2 through the U-shaped fixed connector 33, so that the middle part of the buffer assembly 1 further bends downward, and the two ends of the buffer assembly 1 shrink toward the middle, until the two ends of the buffer assembly 1 are against the limit assembly 2, and the limit assembly 2 limits the further shrinkage of the buffer assembly 1, thereby generating an upward pulling force on the wheel assembly 6 through the buffer assembly 1, thereby reducing the sinking amplitude of the wheel assembly 6. Therefore, through the cooperation of the buffer assembly 1 and the limit assembly 2, the movement stroke of the wheel assembly 6 can be suppressed when it jumps and sinks, thereby achieving the purpose of reducing the jumping amplitude of the wheel assembly 6.
[0040] See also Figure 3 , the second mounting bracket 4 is arranged at one end of the buffer assembly 1, and the second mounting bracket 4 includes a fixed bracket 41, a connecting plate 42 and a columnar structure 43, wherein the fixed bracket 41 is connected to the vehicle frame, one end of the connecting plate 42 is rotatably connected to the fixed bracket 41, both ends of the columnar structure 43 are rotatably connected to the other end of the connecting plate 42, and the cylindrical surface of the columnar structure 43 is also connected to the buffer assembly 1. Therefore, the above connection method enables the connecting plate 42 and the fixed bracket 41 to rotate relative to each other, and the columnar structure 43 and the connecting plate 42 can also rotate, and because the cylindrical surface of the columnar structure 43 is connected to the buffer assembly 1, the columnar structure 43 can better adapt to the deformation of the buffer assembly 1 during the movement of the wheel assembly 6, so that the movement process of the wheel assembly 6 is smoother. A fixed bracket 41 is also provided at the other end of the buffer assembly 1. The setting height of the fixed bracket 41 is lower than the setting height of the fixed bracket 41 at the other end that is relatively set, and the fixed bracket 41 is directly connected to the two ends of the columnar structure 43, and the cylindrical surface of the columnar structure 43 is connected to the cylindrical surface of the buffer assembly 1. Of course, the columnar structure 43 can also rotate relative to the fixed bracket 41, and then through the related structures such as the fixed bracket 41 set at both ends of the buffer assembly 1, it can effectively adapt to various movement states generated by the wheel assembly 6 when passing through a bumpy road.
[0041] In addition, one end of the connecting plate 42 connected to the columnar structural member 43 is suitable for opening a slot 421, and the slot 421 is opened in the horizontal direction. After the opening is completed, the columnar structural member 43 is connected to the slot 421 through a connecting member, and the columnar structural member 43 can move in the slot 421, so as to adapt to the displacement that may be generated when the wheel assembly 6 is bumpy, and further adapt to complex road conditions.
