Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric vehicle controller, more particularly, to a high-efficiency moisture-proof and heat-dissipation electric vehicle controller. BACKGROUND

[0002] The electric vehicle controller is one of the core components of the electric vehicle, which is responsible for controlling the start, operation, advance and retreat, speed and brake of the electric vehicle motor, so as to realize the accurate regulation and control of the vehicle running state. The performance of the electric vehicle controller directly affects the overall performance and service life of the electric vehicle.

[0003] The controller needs to consider waterproof and heat dissipation. Once the waterproof measure is not in place, the humid air or moisture is easy to invade the inside of the controller, causing the circuit board short circuit and the element corrosion, and further causing the controller failure, affecting the normal operation of the electric vehicle, and even possibly causing safety hazards. Under the long-time high-load working condition, the internal temperature of the controller will gradually rise, and if the heat dissipation performance is poor, it will exceed the normal working temperature range. And the existing electric vehicle controller often needs to extend multiple wires in the design. These wires may be pulled by various external forces during vehicle driving, especially in the case of bumpy road or frequent start and stop, the connection part between the end of the wire and the circuit board is easy to loosen, and further has the risk of falling off, which not only may affect the normal work of the controller, but also may cause circuit failure, and even cause safety hazards. In addition, the wires are distributed in a bundle, so that the heat generated when the current passes through cannot be dissipated in time, and is easy to accumulate inside the wire, causing local temperature rise.

[0058] Working principle: the controller of the application first passes the wire upward through the bearing frame and rests on the bearing rod, then passes through the threading channel, the fixing seat and the strip-shaped through groove, and allows the wire to be in a relaxed state in the shell with a certain excess length, and at this time the second heat-conducting plate and the third heat-conducting plate abut together due to the support of the rotating plate, so that the wire has enough threading space, and at this time the wire is not pressed, so it is relatively easy to adjust the length of the wire in the shell to a relaxed state. Then install the strip-shaped rubber part at the position of the strip-shaped through groove and the fixing seat, then raise the lifting seat by the screw rod, so that the wire is also raised, so that the abutting plate abuts all the wires, thereby realizing the abutting and pressing of the wires, so that even if the part of the wire outside the shell is pulled later, it is not easy to cause the wire to fall off the circuit board.

[0059] And with the lifting of the lifting seat, the rotating plate is collected between the two abutting plates, and the second heat-conducting plate and the third heat-conducting plate are reset under the action of their own elasticity, so that the first heat-conducting plate and the second heat-conducting plate wrap the wire from both sides. The third heat-conducting plate is pressed downward from above the bearing frame, thereby abutting the wire, so that the wire is arranged relatively dispersedly on one hand, and on the other hand the wire is abutted by the first, second and third heat-conducting plates, so that the heat is timely conducted away through the first, second and third heat-conducting plates.

[0060] Then the first counterbore can be filled with glue, so that the water-blocking glue fills the strip-shaped inner cavity and the rectangular frame-shaped groove, so that the position of the wire extending out of the shell realizes better water-blocking sealing. Then the first bolt is used to close the first counterbore, and the second bolt is used to close the second counterbore, thereby realizing the sealing of the first and second counterbores of the shell.
