Technical Field
[0001] The utility model relates to the technical field of electric vehicle shock absorption, in particular to a double-axis stable electric motorcycle shock absorber. Background Art
[0002] The shock absorber of an electric motorcycle is mainly used to absorb road vibrations and impacts, and to improve driving stability and comfort. It usually includes a spring and shock-absorbing fluid. The spring is used to absorb impact force, and the shock-absorbing fluid is used to reduce the rebound speed of the spring, thereby achieving a shock-absorbing effect.
[0003] After searching, the existing Chinese patent publication number is: CN220354359U, which provides a dual-axis stable electric vehicle shock absorber. This patent sets two sets of stable auxiliary shock-absorbing structures at the connection position of the existing shock absorber, which can be used in conjunction with the central connecting rod for shock absorption during use. It can not only share the lateral force during the shock absorption process, but also ensure the shock absorption stability of the shock absorber during use, effectively improve the durability of the center position structure of the shock absorber during use, make the overall service life of the shock absorber longer, and the shock absorption comfort during use is better. Compared with the existing shock absorbers, it has better shock absorption, higher safety, stronger durability, longer service life, better stability and other characteristics.

Since electric motorcycles cannot avoid frequent turning and braking during use, the shock absorber will be subjected to excessively frequent multi-directional force activities rather than simple up and down force. Such activities cause certain damage to the shock absorber itself and reduce its service life.
[0005] In view of the above problems, a dual-axis stable electric motorcycle shock absorber is proposed. Utility Model Content

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.
[0033] Combination Figure 1-3 The utility model discloses a dual-axis stable electric motorcycle shock absorber, comprising a shock absorber body 10, a connecting rod 16 is fixedly connected to the bottom of the shock absorber body 10, a matching seat 5 is fixedly connected to the bottom of the connecting rod 16, a movable ball 17 is fixedly connected to the bottom of the matching seat 5, a movable ball sleeve 13 is arranged at the bottom of the movable ball 17, an movable cavity 18 is arranged on the inner wall of the movable ball sleeve 13, and the movable cavity 18 is slidably connected to the outside of the movable ball 17. When the electric motorcycle turns or brakes, its multi-directional force will cause the shock absorber body 10 to tilt accordingly through the mounting head 2, and synchronously drive the movable ball 17 to move synchronously inside the movable cavity 18. The multi-directional force will not affect the mounting head 3, and the shock absorber body 10 and the shock absorbing spring 12, which are mainly used for shock absorption and buffering, have completed the tilting, and will not affect the buffering and shock absorption functions of the device.
[0034] Combination Figure 2-4 A correction component is provided on the outside of the shock absorber body 10, and the correction component includes a fixing block 29, which is fixedly connected to the outer wall of the shock absorber body 10, and a correction spring 6 is fixedly connected to the side of the fixing block 29 away from the shock absorber body 10, and the other end of the correction spring 6 is fixedly connected to a fixing block 1 8, and one side of the fixing block 1 8 is fixedly connected to a fixing plate 1, and the upper and lower sides of the fixing plate 1 are fixedly connected with mounting pieces 7, and the fixing plate 1 is fixed at a specified position by the mounting pieces 7 on the fixing plate 1. When the position between the two shock absorbers changes irregularly, the force is unbalanced, which will pull the correction spring 6 on one side to extend, and the corresponding correction spring 6 on the other side will shrink, so that the position change of the two shock absorbers is prevented to a certain extent, thereby reducing the damage to the shock absorber caused by irregular force, and also plays a certain guiding role when the two shock absorbers restore their original position relationship.
[0035] Combination Figure 2-4 A mounting head 2 is fixedly connected to the top of the shock absorber body 10, and a mounting hole 2 15 is opened on the outer wall of the mounting head 2. A mounting head 2 3 is fixedly connected to the bottom of the movable ball sleeve 13, and a mounting hole 14 is opened on the outer wall of the mounting head 2 3. A thread 11 is opened on the outer wall of the shock absorber body 10, and a matching seat 4 is threadedly connected to the outer wall of the fixed block 29. A shock absorbing spring 12 is sleeved on the outer side of the shock absorber body 10, and the upper and lower ends of the shock absorbing spring 12 are fixedly connected to the matching seat 2 5 and the matching seat 1 4 respectively. The matching seat 1 4 is rotated on the shock absorber body 10 to adjust the tightness of the shock absorbing spring 12 to a suitable position, and the shock absorber is installed at a designated position on the electric motorcycle through the mounting hole 2 15 on the mounting head 2 and the mounting hole 14 on the mounting head 3.
[0036] Working principle: before using the device, the user first conducts a comprehensive inspection of the device to ensure that the device is complete and has no damage, and then installs the device. The shock absorber is installed at the specified position on the electric motorcycle through the mounting hole 2 15 on the mounting head 2 and the mounting hole 14 on the mounting head 3, and then the fixing plate 1 is fixed at the specified position through the mounting piece 7 on the fixing plate 1. Then, the rotating matching seat 4 is rotated on the shock absorber body 10 to adjust the tightness of the shock absorber spring 12 to the appropriate position. After confirming that it is tightened, the installation is completed. When the electric motorcycle turns or brakes, its multi-directional force will pass through the mounting head 2 to cause the shock absorber body 10 to have a corresponding The tilting synchronously drives the movable ball 17 to move synchronously inside the movable cavity 18, and its multi-directional force will not affect the installation head 23. The shock absorber body 10 and the shock absorbing spring 12, which are mainly used for shock absorption and buffering, have completed the tilting and will not affect the buffering and shock absorption functions of the device. When the position between the two shock absorbers changes irregularly, the force is unbalanced, which will pull the correction spring 6 on one side to stretch, and the correction spring 6 on the other side will shrink accordingly. This will prevent the position of the two shock absorbers from changing too much to a certain extent, thereby reducing the damage to the shock absorber caused by irregular force, and also play a certain guiding role when the two shock absorbers restore their original position relationship.
