[0002] Shock absorbers are one of the main accessories of a vehicle. They can absorb and reduce vibrations and bumps caused by uneven roads or other vibration sources during vehicle driving, reduce the impact of bumpy road conditions on vehicle balance, and improve user experience. During application, the shock absorbers are installed in a sliding support structure, which is connected between the vehicle body and the tire.

[0003] The existing sliding support structure is a "冂"-shaped sliding bracket and a guide bracket of the wheel to form a slide rail structure. Although this structure can realize sliding connection more conveniently, it has high requirements on the production and assembly accuracy of the sliding bracket, and it is easy to have unqualified assembly quality and need to be disassembled and reinstalled, affecting production efficiency; and when there is a slight inward contraction deviation or outward expansion deviation on both sides of the sliding bracket, the slide rail structures on both sides of the wheel will not be able to slide in parallel. As the sliding stroke increases, the friction between the guide bracket and the sliding bracket structure will also increase, and part of the impact force will be directly transmitted to the frame through the slide rail structure. The shock absorber cannot achieve the expected shock absorption effect, resulting in a poor user experience. Utility Model Content

[0033] 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 of 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.

[0034] The names in the technical proposal are explained as follows:

[0035] 1. Flexible connection: Compared with the "冂"-shaped rigid connection structure formed by two sliding parts directly connecting the connecting parts, sliding parts facing the top of the "冂"-shaped are arranged at the bottom of the connecting arms on both sides of the "冂"-shaped structure, and the top of the sliding parts has a certain degree of mobility, which is equivalent to arranging sliding parts on both sides of the "冂"-shaped structure through U-shaped structures. The formed connection structure can adapt to larger design and installation errors while meeting the performance requirements, thereby reducing the requirements for processing accuracy and installation accuracy during the production and assembly process.

[0036] In the present embodiment, the vehicles using the shock absorber slide rail connection structure include: a unicycle, an electric wheel balance vehicle, a two-wheel electric vehicle or a motorcycle; in the present specific embodiment, the case of application on an electric balance vehicle is used for illustration.

[0037] Reference Figures 1-6 , one embodiment of the utility model provides a shock absorber slide rail connection structure, the shock absorber slide rail connection structure includes a drive connection component 1 and a frame connection component 2;

[0038] The driving connection assembly 1 is rotatably connected to the driving device, and the driving connection assembly 1 includes a guide assembly 11, and the guide assembly 11 is arranged on both sides of the driving device;

[0039] The frame connection assembly 2 includes a top bracket 21, two connection brackets 22, and a sliding assembly 23. The two connection brackets 22 are located on both sides of the drive connection assembly 1, the top bracket 21 is arranged on the top of the connection brackets 22, and the bottom of the sliding assembly 23 is arranged at the bottom of the connection brackets 22;

[0040] The sliding assembly 23 is slidably connected to the guiding assembly 11; wherein, the frame connection assembly 2 is flexibly connected to the drive connection assembly 1 through the sliding assembly 23.

[0041] In this embodiment, it is avoided that the sliding assembly is directly connected to the top bracket to form a rigid connection, so that the sliding assembly and the top bracket form a more tolerant flexible connection through the connection bracket. When there is a slight deviation of the connection bracket inward or outward expansion, the sliding assembly at the bottom of the connection bracket and the guiding assembly can still maintain parallel sliding, which can effectively reduce the precision requirements during production and assembly, improve the qualification rate of assembly, and then speed up the production efficiency; at the same time, it is avoided that the impact force under bumpy road conditions is directly transmitted to the frame connection assembly through the slide rail structure, so that the shock absorber achieves the expected shock absorption effect and guarantees the user experience.

[0042] In another implementation scenario of this embodiment, the connection bracket 22 can be set to one or more, and one or more connection brackets 22 are arranged adjacent to the drive connection assembly 1.

[0045] In this embodiment, the limit seat 3 can be used for lateral limitation to improve the ability of the connection structure to resist lateral torque, avoid the inclination of the sliding assembly to the outside of the connection bracket 22 when subjected to lateral torque, and thus ensure the up and down parallel sliding of the sliding assembly 23 inside the connection bracket 22.

[0046] In one embodiment, a recess adapted to the outer shape of the sliding assembly 23 is provided in the middle of the limit seat 3, and the recess abuts against the sliding assembly 23.

[0047] In this embodiment, the limit seat 3 limits the sliding assembly 23 through the recess, increasing the contact area and avoiding deformation of the sliding assembly 23 at the contact part;

[0048] In another implementation scenario of this embodiment, the top of the sliding assembly 23 is spaced a predetermined distance from the top of the connecting bracket 22, and the limit seat 3 is spaced the predetermined distance from the top of the connecting bracket 22. By setting the predetermined distance, the limit seat 3 is set at the same height as the top of the connecting bracket 22, and the limit seat can be used to limit the maximum sliding stroke of the sliding assembly to prevent the sliding assembly 23 from detaching from the guide assembly 11, thereby enhancing the overall safety.

[0050] In this embodiment, the shock absorbers connected by the shock absorbing connecting assembly 4 reduce the impact on various components of the vehicle due to vibration and bumps. The shock absorbers can effectively extend the service life of other key components (such as tires, suspension, etc.), reduce the frequency and cost of maintenance and repairs, and improve the user experience.

[0054] In this embodiment, an accommodating gap is formed to avoid the guide component 11 and the sliding component 23, and a fixing seat 223 provided on the mounting plate 222 is used to fix the sliding component 23 to prevent the sliding component 23 from separating and falling off from the connecting bracket 22.

[0055] In one embodiment, the first connecting member 221 includes a battery compartment, and the battery compartment is disposed inside the first connecting member 221 or on an outer side of the first connecting member 221 .

[0057] In one embodiment, the first connecting member 221 includes a hinge bracket 224 which is arranged at the bottom of the first connecting member 221, and a foot pedal 5 is rotatably arranged on the hinge bracket 224.

[0058] In this embodiment, the foot pedal 5 is a platform for the user to stand on, enabling the user to stand on the unicycle to maintain balance and control. Moreover, by hingedly arranging the foot pedal 5 on the first connecting member 221, the impact force is prevented from being directly transmitted to the user, and it is better to maintain balance when driving on bumpy roads. At the same time, the hinged foot pedal 5 can also be flipped and stored when not in use.

[0059] Refer to Figure 4 and Figure 5 In one embodiment, the drive connection assembly 1 further includes a second connecting member 12. The guiding assembly 11 includes a second connecting plate 13 and a guiding sleeve 14 arranged on the second connecting plate 13, and the second connecting member 12 is connected between the two second connecting plates 13;

[0061] The sliding assembly 23 is slidably arranged in the guiding sleeve 14.

[0062] In this embodiment, the second connecting member 12 is used to keep the second connecting plates 13 synchronized and guide the sliding assembly 23 through the guiding sleeve 14.
