Embodiment

[0023] Such as Figure 4 As shown, the application of the motor low-voltage wire harness integration device 11 on a certain new energy vehicle example motor 12 is as follows: The motor low-voltage wire harness integration device 11 is installed at the rear end of the example motor 12, and passes through the rubber seal block 8 to pass through the motor housing 13. The rubber sealing block 8 is stuck in the sealing groove of the motor housing 13. Through the installation and cooperation of the housing and the end cover, the rubber sealing block 8 is compressed to achieve the cylinder seal of the low-voltage wire harness 9, and the part of the example motor 12 waterproof and dustproof (i.e. IP protection) requirements; one end of the low-voltage wire harness 9 on the motor low-voltage wire harness integration device 11 is directly connected to the resolver stator 6, and the other end is directly connected to the PIN pin connector 7, and the PIN pin connector 7 extends out. Exampl...

Abstract

The invention provides a low-voltage wire harness integration device for a drive motor of a new energy vehicle. The device comprises a PIN connector, a rubber sealing block, a low-voltage wire harness, a temperature sensor wire harness connector and a rotary variable rotor, wherein the low-voltage wire harness and the rotary variable rotor of the motor are integrated into a whole; one end of the low-voltage wire harness is connected with the universal PIN connector while the other end is connected with the rotary variable rotor, and no transitional PIN connection or manual wiring connection exists between the low-voltage wire harness and the rotary variable rotor; the rubber sealing block is integrated into the low-voltage wire harness, and clamped into a sealing groove of the motor shell, and wire harness can be sealed and pass through the motor shell by the compression of the sealing block. The device adopts the integrated design of the low-voltage wire harness and the rotary variable rotor of the motor, thus the probability that a connection error occurs at the low-voltage wire harness can be greatly reduced, the structure is compact, the installation is convenient and fast, and the system cost is low.

Description

technical field [0001] The invention relates to the technical field of low-voltage wire harnesses for drive motors used in new energy vehicles, in particular to an integrated device for low-voltage wire harnesses and resolver stators. Background technique [0002] The new energy vehicle drive motor low-voltage wiring harness is mainly used to connect the temperature sensor wiring harness for measuring the temperature of the motor winding, the resolver wiring harness for measuring the position of the motor rotor, and the low-voltage wiring harness for the motor inverter. The motor temperature sensor wiring harness and the motor resolver wiring harness are generally arranged inside the motor casing, and the motor inverter low-voltage wiring harness is arranged outside the motor casing. The motor low-voltage wiring harness needs to pass through the motor casing to realize the internal and external low-voltage components of the motor. Connection. Therefore, considering the safe...
