[0043] Specifically, the hanging portion 211 is used to cooperate with the limiting surface 222 to limit the push rod 21 when the push rod 21 moves downward to the maximum position. The hanging portion 211 can be constructed as a protruding structure, and the protruding structure is arranged on the outer peripheral wall of the push rod 21 and extends outward from the outer peripheral wall of the push rod 21 along the radial direction of the push rod 21, so that the protruding structure has a certain length in the radial direction of the push rod 21, so as to cooperate with the limiting surface 222 to limit the push rod 21 when it moves downward to the maximum position, and the limiting The positioning surface 222 is formed at the upper end of the movable groove 22, so that the protruding structure can form a stop surface 212.

[0063] Further, when the user presses the electronic brake button 1, the electronic brake button 1 can push the gear pin 25 to move downward to switch the vehicle gear. At this time, the second elastic member 26 is compressed. When the force applied by the user to the electronic brake button 1 disappears, the second elastic member 26 can stretch under the action of the restoring force and push the gear pin 25 to move upward to press the electronic brake button 1 until it is reset to provide a prerequisite for the next movement, that is, the second elastic member 26 can apply an elastic force to the gear pin 25 to press toward the electronic brake button 1. Among them, the second elastic member 26 can be a spring.

[0064] In some embodiments, the switch body 2 is further provided with a circuit board 28 , and the circuit board 28 is electrically connected to the micro switch 24 .

[0065] Specifically, by electrically connecting the circuit board 28 to the micro switch 24, the transmission of electrical signals can be achieved. When the micro switch 24 converts the mechanical action on the electronic brake button 1 into an electrical signal, the electrical signal can be transmitted to the circuit board 28. The circuit board 28 can further send the electrical signal to the electronic control unit. The electronic control unit will control the motor driver to activate or release the parking brake, thereby realizing the vehicle parking brake or handbrake unlocking.

[0066] The electronic brake button 1 is provided with a light emitting component 12 , and the circuit board 28 is provided with a light source component, which is suitable for guiding light toward the light emitting component 12 through the light guide 13 .

[0067] Specifically, a light source is provided on the circuit board 28, and the light source can be used to emit light. The light guide 13 can be used to guide the light emitted by the light source and irradiate the light toward the light-emitting component 12, so that the light-emitting component 12 can emit light, thereby improving the visibility of the electronic brake button 1, and indicating the current state of the electronic brake button 1, thereby improving the functionality of the electronic brake button 1 and improving the user experience.

[0068] And, if Figure 1 and Figure 3As shown, a waterproof rubber 29 is further provided in the switch body 2, and the waterproof rubber 29 is provided above the micro switch 24 and the circuit board 28. The installation position of the switch assembly 100 is close to the water cup placement area. When the vehicle stops suddenly or vibrates during driving, or when passengers take drinks, it is easy to cause liquid to splash onto the surface of the electronic brake button 1 and penetrate into the switch assembly 100, causing a short circuit. The waterproof rubber 29 can effectively prevent liquid from penetrating into the switch assembly 100, protect the circuit board 28 and solder joints, etc., avoid short circuits and ablation, and improve the safety of the switch assembly 100. The switch body 2 also includes a base 30, which is provided at the bottom of the switch body 2 and is used to support the components in the switch body 2.

[0069] The utility model also provides a vehicle.

[0070] According to the vehicle of the embodiment of the utility model, any of the switch assemblies 100 described above is provided. By arranging a push rod 21 between the electronic brake button 1 and the micro switch 24, and making the push rod 21 movable in the movable groove 22, the mechanical action of the electronic brake button 1 is transmitted to the micro switch 24, the parking brake or hand brake of the vehicle is unlocked, and the upper end of the movable groove 22 is formed with a limit surface 222, and a hanging part 211 is provided on the push rod 21, and the maximum position of the downward movement of the push rod 21 is limited by the cooperation between the hanging part 211 and the limit surface 222 to prevent the push rod 21 from falling out. The structure is simple and reliable, and rework can be reduced, which is conducive to improving production efficiency and product quality.
