Compression joint-type electric vehicle controller for double-row power tube leaf spring

Abstract

The invention discloses a compression joint-type electric vehicle controller for a double-row power tube leaf spring. The compression joint-type electric vehicle controller comprises a hollow shell in the middle, and a front baffle and a rear baffle at two ends, wherein a front sealing gasket and a rear sealing gasket are arranged between the front baffle and the shell, and between the rear baffle and the shell, and eighteen power tubes welding on a circuit board, function lines, power lines and a leaf spring for in compression joint with the power tubes are contained inside the controller. The compression joint-type electric vehicle controller is characterized in that the bottom of the hollow shell is arch-shaped, and strip-shaped heat dissipation teeth are distributed on the outer surface of the shell; two rows of salient points are arranged on each heat dissipation tooth; twelve small holes are respectively formed in the front baffle and the rear baffle; the leaf spring is provided with twenty-two pins; the eighteen power tubes welded on the circuit board are divided into two rows and are uniformly distributed on two sides of the circuit board; the eighteen power tubes pass through the bottom of the shell by adopting compression joint screws; the leaf spring is in compression joint, so that the leaf spring deforms to generate elastic force. The elastic force is applied to the power tube bodies through the pins on the leaf spring, so that the power tubes are tightly attached to the inner surface of the shell, the heat conduction path is the shortest, and the timeliness and the effectiveness of heat conduction are guaranteed.

Description

technical field [0001] The invention relates to a controller for an electric vehicle, in particular to a double-row power tube spring leaf pressing type electric vehicle controller. Background technique [0002] With the development of society and the continuous increase of fuel vehicles, the shortage of natural resources such as petroleum fuels and the global warming caused by fuel emissions have become increasingly prominent. Therefore, in this context, hybrid or pure power vehicles have gradually entered people's lives, and electric vehicles have emerged as the times require. The controller is the core component of the electric vehicle. It controls the electric current of the motor to ensure the power required for the vehicle to run, and plays a vital role in ensuring the normal running and safety of the vehicle. Most electric vehicle controllers in the state of the art are power tubes arranged in a row, which are fixed on the side wall of the hollow housing through the ...

AI Technical Summary

Problems solved by technology

[0003] The power tubes are distributed in a single row, and the heat generated by the power tubes is too concentrated during operation. In addition, the heat conduction path is too long when the heat is transmitted to the aluminum heat dissipation shell through the heat conduction aluminum strip, and the heat dissipation effect is poor. The power tube is burnt out and fails, and the controller function is lost

[0004] Affected by the quality of the thread on the heat-conducting aluminum strip, the locking force of individual power tubes and heat-conducting aluminum strips is small when the screws are locked or the wires are slippery, resulting in poor fit of some power tubes, and the heat of the power tubes cannot be effectively conducted out, causing some The power is burned out and the controller function is lost
