Problems solved by technology

However, there are still some deficiencies in the current improvement scheme: (1), the signal line connector that leads out the control signal line just simply extends out of the shell, and the connector at one end of the line is inserted into the end of the welding plate, and only a simple positioning process is done , causing the connector to be easily loosened during the running vibration of the vehicle, and it is also easy to be pulled and unplugged from the outside; (2), various wire harnesses are drawn from the top of the controller, and the overall visual e

Example Embodiment

[0040] Example 1

[0041] Such as figure 1 , Figure 5 Shown: the electric vehicle controller in the embodiment is mainly composed of a controller housing and a circuit board 15. The circuit board 15 is installed in the controller housing, and the circuit board 15 is provided with a signal wire connection connector 3 and a large current connection The terminal 16 and the power semiconductor device 20, the signal wire connection connector 3 is used for connecting the control signal wire 7, the high current connection terminal 16 is used for connecting the power wire or the motor phase wire 6; the signal wire connection connector 3 It includes a wiring connector socket 3.1 and a pluggable wiring connector plug 3.2. The wiring connector socket 3.1 and the high-current terminal 16 are arranged on the circuit board 15 at a position near the front side of the controller housing. A junction box 1a recessed downward is provided on the side. The bottom of the junction box 1a is provided w...

Example Embodiment

[0062] Example 2

[0063] The difference between the second embodiment and the first embodiment is only the difference in the pressing method of the power semiconductor device 20. In the second embodiment, the power semiconductor device 20 is compressed by a T-head compression column 22, a compression screw 23, and a connecting bar. 24 combination to implement compression, no support soft rubber pad 19 is provided.

[0064] Such as Figure 13 As shown, in Embodiment 2, the circuit board 15 is provided with a plurality of large mounting through holes 15a at a position outside the power semiconductor device 20, and the pressure plate 21 and the housing body 1 are respectively provided with a plurality of large mounting holes 15a. The mounting through holes 15a correspond to the small mounting through holes 21a and screw holes one by one. A hollow T-head pressing column 22 is installed in the large mounting through hole 15a, and the central hole of the T-head pressing column 22 A com...

Abstract

The invention relates to an electric vehicle controller which comprises a controller shell and an internal circuit board, wherein a signal line wiring connector, large current wiring terminals and a power semiconductor device are arranged on the circuit board; the signal line wiring connector comprises a wiring connector socket and a pluggable wiring connector plug; the wiring connector socket and the large current wiring terminals are arranged at positions close to the front side of the circuit board; a wiring box which concaves downwards is arranged on the front side of the controller shell; through holes of which the shapes and sizes correspond to those of the wiring connector socket and the large current wiring terminals are formed in the bottom of the wiring box; the wiring connector socket and the upper parts of the large current wiring terminals respectively penetrate through corresponding through holes and are positioned inside the wiring box; the wiring box is covered by a wiring box cover plate; and the signal line wiring connector and the wires of the large current wiring terminals are all led out from a side surface of the controller shell. The electric vehicle controller is not only tidy and ordered in external wiring and is attractive and graceful, but also stable to operate and safe and reliable.

Description

technical field [0001] The invention relates to an accessory part of an electric vehicle, in particular to an electric vehicle controller, belonging to the technical field of electric vehicle design. Background technique [0002] Electric vehicle (including two-wheel, three-wheel, and four-wheel electric vehicle) controllers have more control signal lines in order to realize external operations on the controller. At the same time, in order to drive the power motor of the electric vehicle, it is necessary to connect a high-power power supply line and a phase line of the motor. [0003] The traditional method of connecting control signal lines and high-power power lines or motor phase lines is as follows: weld the wires on the circuit board inside the controller, then lead the wires out of the controller, and connect them outside the controller in a wire-to-wire manner. Air docking through connectors. This original and simple connection method causes a large number of connec...
