[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention provides Figure 1-3 As shown, a shock absorbing structure in a wheel hub motor comprises a car tire 1 and a car shock absorbing structure 7 arranged at the right side of the car tire 1; a shock absorbing damping spring 8 is arranged on the car shock absorbing structure 7; a movable sliding groove 11 is arranged at the middle position of the car shock absorbing structure 7, a limited position clamping groove 14 is arranged at the upper side position of the movable sliding groove 11, a connecting plug strip 15 is arranged at the middle position of the movable sliding groove 11, a connecting extrusion spring 12 is arranged at the inner position of the connecting plug strip 15, and a connecting extrusion spring 12 is arranged at the upper side position of the connecting extrusion spring 12. A buckling ball 13 is arranged at the side position, an external connecting strip 9 is arranged at the side position of the connecting strip 15, and a connecting brush 10 is arranged at the inner side position of the external connecting strip 9. When the automobile shock-absorbing structure 7 is running, the vibration drives the external connecting strip 9 to rotate to scrape the position of the shock-absorbing damping spring 8. The rotation and the upward and downward extension of the damping spring can brush the surface of the damping spring, and dust can be removed, thereby effectively reducing the accumulation of dust, thereby effectively improving the practicality of the shock-absorbing structure in the wheel hub motor.

[0024] like Figure 1As shown, a connecting shaft 6 is provided at the bottom of the automobile shock absorbing structure 7, and the connecting shaft 6 is connected to the automobile tire 1 through a plane bearing base. The connecting shaft 6 is widely used in various mechanical transmissions and engineering equipment, and is an indispensable component in mechanical transmission. The connecting shaft 6 transmits energy such as torque, rotation speed and power to realize the transmission and control of various motion modes, so that the machine can operate normally.

[0025] like Figure 1 As shown, a car air brake 4 is arranged at the side position of the connecting shaft 6, and a tire brake 3 is arranged at the middle position of the car tire 1. The tire brake 3 is driven and used by the car air brake 4. The car air brake 4 controls the braking system of the vehicle through compressed air. The characteristics of the car air brake mainly include fast response speed and strong braking force.

[0026] like Figure 1 As shown, an inner connecting spring 5 is provided at the side position of the automobile air brake 4, and the inner connecting spring 5 is used to connect the stator and the rotor to the connecting shaft 6, and the role of the stator and the rotor is key. The hub motor is a design that embeds the motor directly into the wheel, wherein the stator is fixed to the tire and the rotor is fixed to the axle. When the power is turned on, the relative movement between the stator and the rotor controls the order and time of activation of the stator winding through the electronic commutator (switching circuit) and the signal of the position sensor, generates a rotating magnetic field and rotates the rotor. This design integrates the power, transmission and braking devices into the wheel hub, greatly simplifying the mechanical part of the electric vehicle. This structure of the hub motor allows the vehicle to convert electrical energy into mechanical energy more directly and efficiently, thereby driving the vehicle forward or backward.

[0027] like Figure 1 As shown, a flexible coupling 2 is provided near the left end of the automobile tire 1. The flexible coupling 2 is a coupling that allows the rotor to have a separate axial displacement and a certain deviation in the alignment of the two connected rotors. The flexible coupling is a coupling that has a first hub and a second hub, each of which has a flange and is connected to the transmission shaft. Each coil spring is supported in a spring hole so that the adjacent end faces of the coil spring are in contact and connected in series with each other.

[0028] like Figure 1 As shown, the automobile tire 1 is made of rubber material. The automobile tire 1 is a circular elastic rubber product that rolls on the ground. Rubber not only has excellent wear resistance and long service life, but also has good elasticity. As a tire, it can absorb a lot of vibration energy, which is beneficial to the smooth driving of the car. Therefore, rubber is used to make automobile tires.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
