Description

Technical Field

[0001] This utility model relates to a scooter structure, and more particularly to a scooter shock absorber. Background Technology

[0002] As a popular mode of transportation, the comfort and safety of scooters are crucial to the user experience. Shock absorbers are a key component of scooters, effectively reducing vibrations and impacts caused by uneven road surfaces, thus improving riding comfort and stability. However, existing scooter shock absorber technology has some shortcomings. Some shock absorbers use spring or hydraulic systems, which, while providing some damping, are often complex in structure, bulky, and heavy, making them unsuitable for the design requirements of lightweight scooters. Furthermore, the damping effect of these shock absorbers may not be ideal, failing to fully absorb vibrations from uneven road surfaces, leading to discomfort for users during extended rides. Other shock absorbers are difficult to install, and components are prone to damage due to loosening or wear, thus affecting the scooter's lifespan and maintenance costs. Utility Model Content

An outer layer of elastic rubber is also provided between the rigid central shaft and the frame connector. A fixing cover secures the rigid central shaft within the frame connector. The connecting shaft of the shock-absorbing shaft passes through a limiting hole in the fixing cover and connects to a fork arm connecting block. The limiting block of the fixing cover and the limiting notch of the fork arm connecting block cooperate to limit the movement. This utility model, through the innovative design of the shock-absorbing shaft and the outer layer of elastic rubber, combined with the ingenious cooperation between the fixing cover and the fork arm connecting block, provides superior shock absorption, a simpler structure, lighter weight, and easier installation, solving the problems of unsatisfactory shock absorption, complex structure, heavy weight, and difficult installation in existing technologies.

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0014] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0016] like Figure 1 , Figure 2As shown, the scooter shock absorber disclosed in this utility model mainly consists of a frame connector 1, a shock-absorbing shaft 2, a fixing cover 6, and a fork arm connecting block 7. This shock absorber achieves excellent shock absorption through innovative structural design, while also possessing advantages such as simple structure, light weight, and convenient installation.

[0017] A scooter shock absorber includes: a frame connector 1, a shock-absorbing shaft 2, a fixing cover 6, and a fork arm connecting block 7. The frame connector 1 is sleeved with the shock-absorbing shaft 2. The outer surface of the rigid central shaft 4 of the shock-absorbing shaft 2 is provided with an outer layer of elastic rubber 5. The rigid central shaft 4 is made of rigid material and plays a supporting and force-transmitting role. The outer layer of elastic rubber 5 wraps around the outer surface of the rigid central shaft 4 and has good elasticity and resilience, which can effectively absorb and buffer external impacts.

[0018] The frame connector 1 is the connecting component between the shock absorber and the scooter frame, and it has an internal cavity to accommodate the shock absorber shaft 2. The shock absorber shaft 2 is installed in the frame connector 1 by a sleeve connection. An outer layer of elastic rubber 5 is provided between the rigid bottom axle 4 and the frame connector 1. The outer circle of the outer layer of elastic rubber 5 is interference-fitted with the inner diameter of the frame connector 1 to ensure that the shock absorber shaft 2 is firmly fixed in the frame connector 1 and prevents it from loosening.

[0019] The fixed cover 6 fixes the rigid bottom shaft 4 inside the frame connector 1. The connecting shaft 3 of the shock-absorbing shaft 2 passes through the limiting hole 61 of the fixed cover 6 and is connected to the fork arm connecting block 7. The connecting shaft 3 and the limiting hole 61 are clearance-fitted to ensure that the connecting shaft 3 can rotate or move freely in the limiting hole 61 to adapt to the displacement requirements during the shock absorption process.

[0020] The limiting block 62 of the fixed cover 6 cooperates with the limiting notch 8 of the fork arm connecting block 7 to limit the rotation range of the fork arm connecting block 7, preventing excessive rotation from damaging the shock absorber.

[0021] Furthermore, the fork arm connecting block 7 is a connecting component between the shock absorber and the scooter fork arm, and it is provided with a connecting hole that mates with the connecting shaft 3 and a limiting notch 8. The connecting shaft 3 has an irregular shape that matches the connecting hole of the fork arm connecting block 7, ensuring a tight connection and effective force transmission between the two.

[0022] Further, the outer circle of the outer layer of elastic rubber 5 is interference-fitted with the inner diameter of the frame connector 1, and the connecting shaft 3 is clearance-fitted with the limiting hole 61.

[0023] The working principle of this utility model is as follows:

[0024] When the scooter travels on uneven surfaces, the fork arm connecting block 7 experiences impact from the ground, which is transmitted to the shock-absorbing shaft 2 via the connecting shaft 3. Under the impact, the outer layer of rebound rubber 5 undergoes elastic deformation, absorbing and dispersing the impact energy, thereby reducing the vibration transmitted to the frame connecting part 1 and the frame. Simultaneously, because the connecting shaft 3 and the limiting hole 61 are clearance-fitted, the connecting shaft 3 is allowed to move freely within a certain range, further buffering the impact. During the shock absorption process, the limiting block 62 of the fixing cover 6 and the limiting notch 8 of the fork arm connecting block 7 cooperate to ensure that the fork arm connecting block 7 moves within a predetermined range of motion, avoiding excessive rotation or displacement and protecting the structural integrity of the shock absorber.

[0025] This utility model, through the innovative design of the shock-absorbing shaft 2 and the outer layer of elastic rubber 5, combined with the ingenious cooperation of the fixing cover 6 and the fork arm connecting block 7, provides a superior shock absorption effect, a simpler structure, a lighter weight, and easier installation, solving the problems of unsatisfactory shock absorption effect, complex structure, heavy weight, and difficult installation in the prior art.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
