Description

Technical Field

[0001] The utility model relates to the technical field of braking systems, and specifically relates to a power device structure applied to a dry brake. Background Art

[0002] At the present stage, the braking field adopts a wet separation braking scheme of OneBox or TwoBox with a front caliper and an EPB rear caliper. This scheme has been widely promoted and recognized in the market, but this non-fully decoupled scheme still has its limitations, that is, the whole system is still based on a hydraulic basis and still requires a large number of hydraulic components and brake fluid. Inevitably, there will be potential safety hazards caused by brake fluid leakage, and at the same time, the layout of the vehicle's hydraulic circuit needs to be considered.

[0003] In addition, due to the highly integrated and redundant requirements for separate control of the EMB electronic actuator, the electronic controller of the brake needs to be integrated on the overall brake, which is convenient for responding to the driver's operation in a timely manner, controlling the cooperation of electronic components such as the motor and sensors inside the brake, and interacting the power supply and signals with the vehicle ECU through an integrated wiring harness. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a power device structure applied to a dry brake. The structure form of the PowerPACK combines the mechanical structure and the EMB controller more closely and flexibly, with a higher integration degree and less use of wiring harnesses, enabling the motor control to have a faster response speed.

[0005] To achieve the above object, a power device structure applied to a dry brake is designed, including a PCBA board and an electronic control housing. It is characterized in that: the PCBA board is connected above the electronic control housing; one side of the bottom of the electronic control housing is connected to a signal interface, and a first signal pin is arranged inside the signal interface; the other side of the bottom of the electronic control housing is connected to an electrical interface, and a second signal pin and a power pin are arranged inside the electrical interface. A spring pin interface is arranged on one side of the electrical interface, and a spring pin is arranged inside the spring pin interface.

[0006] One end of the signal interface is connected to the electronic control housing, and the other end of the signal interface is connected to a signal interface seal ring.

[0007] One end of the electrical interface is connected to the electronic control housing, and the other end of the electrical interface is connected to an electrical interface seal ring.

[0008] One end of the first signal pin is located above the electronic control housing, and the other end of the first signal pin penetrates through the electronic control housing and is located on the side of the electronic control housing.

[0009] One end of the second signal pin and the power supply pin is located above the electronic control housing, and a heat sink is sleeved on the upper parts of the second signal pin and the power supply pin; the other ends of the second signal pin and the power supply pin are located inside the electrical interface.

[0010] One end of the spring pin is connected to the electronic control housing, and the other end of the spring pin is located below the spring pin interface.

[0011] The PCBA board is connected to the electronic control housing through a plurality of fixing bolts.

[0012] Compared with the prior art, the present invention provides a power device structure applied to a dry brake. The structure of the PowerPACK is more compact and flexibly combines the mechanical structure and the EMB controller, with higher integration and less harness usage, enabling faster response speed for motor control.

[0013] Based on the fully decoupled solution of integrating the EMB controller into the caliper, the present invention eliminates the presence of vehicle-end hydraulics and avoids hydraulic-related risks. The PowerPACK structure that closely combines the EMB controller and the mechanical structure saves the harness between the controller and the motor. It is highly integrated in structure, convenient for loading and unloading, and enables faster interaction speed between the controller and motor control; it has better performance in terms of the anti-interference ability of the controller and external radiation interference in electromagnetic compatibility (EMC).
