[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Figure 1 This is a structural diagram of the vehicle brake opening mechanism of the utility model.

[0015] See Figure 1 The vehicle group brake opening mechanism provided by the present invention is composed of three parts: a lifting assembly, a base frame 1, and a drive assembly. It is mainly used for opening and closing the brake lever of the EMS trolley drive motor in the final assembly workshop. The lifting assembly and the drive assembly are arranged on the base frame 1. The lifting assembly includes a lifting frame 5, on which a slider 6 and a shift lever 3 are provided. Two induction switches are provided on the base frame 1, one induction switch senses the lowering position of the lifting assembly, and the other induction switch senses the raising position of the lifting assembly. The top of the lifting frame 5 is connected to the mounting beam 2, and a guide rail 10 is provided on the lifting frame 5. The drive assembly includes a motor 7 and a transmission shaft. One end of the transmission shaft is connected to the motor through a coupling, and the other end is connected to a cam 8. The cam 8 and the shift lever 3 are in contact with each other. The shift lever 3 is fixed on the shift lever mounting beam 9, and the end thereof is opened outward in an eight-shaped shape.

[0016] The train brake opening mechanism provided by the present invention comprises a protective cover 4 disposed on the outer side of the lifting frame 5. The lifting frame 5 is also provided with a limit block 13 for controlling the lifting travel of the slider 6. Preferably, the guide rail on the lifting frame 5 is a C-shaped guide rail. The drive assembly also includes a bearing seat and a bearing seat mounting bracket.

[0017] The train brake release mechanism provided by this utility model is arranged along the trolley's direction of travel. Because the end of the lever 3 opens outward in an outwardly splayed shape, the brake lever's entry is shaped like a trumpet, forming a lever cavity. This allows for the introduction of force through the trumpet even when the trolley motor's brake lever deviates from its upper or lower position. The base frame 1 is equipped with two inductive switches, one at the lower and one at the upper position, to sense the lowering and raising positions of the lift assembly, respectively. One switch is mounted on the raising position sensor mounting bracket 11, and the other on the lowering position sensor mounting bracket 12.

[0018] The utility model provides a vehicle group brake opening mechanism. The provided induction switch senses that when the trolley brake rod completely enters the lever cavity, the driving motor 7 rotates, driving the cam 8 to rotate. The cam 8 lifts the lifting frame 5, thereby driving the lever 3 to move upward to open or close the trolley group motor brake rod.

[0019] In summary, the vehicle group brake opening mechanism provided by the present invention can not only quickly and automatically sense the falling and rising of the lifting component, but also has a simple structure, is safe and reliable, and is easy to install and maintain.

[0020] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
