Description

Technical Field

[0001] This utility model relates to a shock-absorbing wheel rim. Background Technology

[0002] In today's transportation sector, whether it's automobiles, motorcycles, bicycles, or various construction machinery vehicles, the wheel rim is a crucial component of the wheel, playing a vital role in supporting the tire, transmitting vehicle load and power, and ensuring smooth vehicle operation. It not only bears the weight of the vehicle itself and additional loads from passengers and cargo, but also constantly endures impacts and vibrations from uneven road surfaces during vehicle operation. Traditional wheel rims lack effective shock absorption mechanisms, which, under prolonged impact, can affect their lifespan. Utility Model Content

[0003] The main objective of this invention is to provide a shock-absorbing wheel rim to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved by adopting the following technical solution:

[0005] A shock-absorbing wheel rim includes a wheel ring, a connecting ring disposed on the inner wall of the wheel ring, a fixing plate disposed at the center of the connecting ring, inner sliding cylinders evenly distributed along the circumference of the outer wall of the fixing plate, a sliding block disposed inside the inner sliding cylinder, an outer sliding cylinder disposed outside the sliding block, the outer side of the outer sliding cylinder being connected to the connecting ring, an inner spring disposed between the inner bottom surface of the inner sliding cylinder and the bottom surface of the sliding block, and an outer spring disposed between the inner bottom surface of the outer sliding cylinder and the top surface of the sliding block.

[0006] Preferably, five inner sliding cylinders are provided, and the five inner sliding cylinders are evenly distributed on the outer wall of the fixed plate along its circumference.

[0007] Preferably, there are three inner springs and three outer springs, with the three inner springs evenly distributed on the inner bottom surface of the inner sliding cylinder and the three outer springs evenly distributed on the inner bottom surface of the outer sliding cylinder.

[0008] Preferably, the inner bottom surface of the inner sliding cylinder is provided with an inner guide rod along its length, the inner bottom surface of the outer sliding cylinder is provided with an outer guide rod along its length, and the sliding block is provided with a guide groove that passes through it along its length. The inner guide rod and the outer guide rod are respectively inserted into the two ends of the guide groove.

[0009] Preferably, the inner guide rod and the outer guide rod are respectively located at the center of the inner spring and the outer spring.

[0010] Preferably, the outer sliding cylinder is provided with a snap-fit ​​groove on its outer side, and the snap-fit ​​groove snaps onto the connecting ring.

[0011] Preferably, the outer sliding cylinder is provided with first fixing holes on the upper and lower sides of the snap-fit ​​groove, and the connecting ring is provided with second fixing holes that cooperate with the first fixing holes.

[0012] The beneficial technical effects of this utility model are as follows:

[0013] This invention utilizes inner and outer springs on both sides of the sliding block. When vibrations occur, the inner and outer springs absorb the shocks and guide the sliding block to move up and down, achieving multi-directional uniform shock absorption. This effectively absorbs road impacts and improves driving smoothness and stability. The inner and outer guide rods ensure linear movement of the sliding block during sliding, preventing deviation and jamming, thus providing a stable shock absorption effect.

[0023] like Figures 1-6As shown, the shock-absorbing wheel rim provided in this embodiment includes a wheel rim 1, a connecting ring 2 is provided on the inner wall of the wheel rim 1, a fixing plate 3 is provided at the center of the connecting ring 2, inner sliding cylinders 4 are evenly distributed along the circumference on the outer wall of the fixing plate 3, a sliding block 5 is provided inside the inner sliding cylinder 4, an outer sliding cylinder 6 is provided on the outer side of the sliding block 5, and the outer side of the outer sliding cylinder 6 is connected to the connecting ring 2. An inner spring 7 is provided between the inner bottom surface of the inner sliding cylinder 4 and the bottom surface of the sliding block 5, and an outer spring 8 is provided between the inner bottom surface of the outer sliding cylinder 6 and the top surface of the sliding block 5.

[0024] The two ends of the inner spring 7 are fixedly connected to the inner sliding cylinder 4 and the sliding block 5, respectively, and the two ends of the outer spring 8 are fixedly connected to the outer sliding cylinder 6 and the sliding block 5, respectively.

[0025] During driving, if vibration is encountered, the inner spring 7 and the outer spring 8 will absorb the vibration, and the sliding block 5 will move up and down under the action of the inner spring 7 and the outer spring 8, thereby achieving the effect of buffering and shock absorption.

[0026] In this embodiment, as Figure 1 As shown, there are five inner sliding cylinders 4. The five inner sliding cylinders 4 are evenly distributed on the outer wall of the fixed plate 3 and along its circumference to ensure that the shock absorption performance of the wheel rim is consistent in all directions and improve the stability and smoothness of driving.

[0027] In this embodiment, as Figure 4 As shown, there are three inner springs 7 and three outer springs 8. The three inner springs 7 are evenly distributed on the inner bottom surface of the inner sliding cylinder 4, and the three outer springs 8 are evenly distributed on the inner bottom surface of the outer sliding cylinder 6, to ensure the shock absorption effect and avoid the difference in shock absorption effect caused by uneven distribution of springs.

[0028] In this embodiment, as Figure 4 As shown, an inner guide rod 9 is provided on the inner bottom surface of the inner sliding cylinder 4 along its length direction, and an outer guide rod 10 is provided on the inner bottom surface of the outer sliding cylinder 6 along its length direction. A guide groove 11 is provided inside the sliding block 5 along its length direction to pass through it. The inner guide rod 9 and the outer guide rod 10 are respectively inserted into the two ends of the guide groove 11 to provide guidance for the sliding block 5, ensure its stability and accuracy during the sliding process, and avoid the occurrence of deviation and jamming.

[0029] In this embodiment, as Figure 4 As shown, the inner guide rod 9 and the outer guide rod 10 are respectively set at the center of the inner spring 7 and the outer spring 8 to ensure the symmetry and stability of the inner spring 7 and the outer spring 8 during compression and rebound, and to avoid the decrease in shock absorption effect caused by the skewness of the inner spring 7 and the outer spring 8.

[0030] In this embodiment, as Figure 6As shown, the outer sliding cylinder 6 is provided with a snap-fit ​​groove 12 on its outer side. The snap-fit ​​groove 12 snaps onto the connecting ring 2, resulting in a larger contact area and a tighter connection.

[0031] In this embodiment, as Figure 6 As shown, the outer sliding cylinder 6 has first fixing holes 13 on the upper and lower sides of the snap-fit ​​groove 12, and the connecting ring 2 has second fixing holes 14 that cooperate with the first fixing holes 13. When connecting, press the outer sliding cylinder 6 inward so that the snap-fit ​​groove 12 snaps onto the connecting ring 2, and then use bolts to connect, which is convenient for installation and disassembly.

[0032] In summary, in this embodiment, by setting inner springs 7 and outer springs 8 on both sides of the sliding block 5, when vibrations occur, the inner springs 7 and outer springs 8 absorb the vibrations and guide the sliding block 5 to move up and down, achieving multi-directional uniform shock absorption, effectively absorbing road impacts, and improving driving smoothness and stability. By setting inner guide rods 9 and outer guide rods 10, the linear movement of the sliding block 5 during the sliding process is ensured, avoiding deviation and jamming, thereby providing a stable shock absorption effect.
