High-performance power-assisted steering electronic control box

Abstract

The invention discloses a high-performance power-assisted steering electronic control box. A motor power supply plug connector and a sensor signal plug connector are integrally formed through injection molding and arranged on the front side wall of a cover plate. A vehicle body power supply plug connector and a vehicle body signal plug connector are integrally formed through injection molding and arranged the rear side wall of the cover plate. The motor power supply plug connector is transversely arranged. The sensor signal plug connector, the vehicle body power supply plug connector and the vehicle body signal plug connector are vertically arranged. The height of the cover plate gradually decreases from the middle to the front portion, and the height of the cover plate is kept unchanged from the middle to the rear portion. With the halving line, in the left and right direction, of a shell of the electronic control box serving as a boundary, the motor power supply plug connector and the vehicle body power supply plug connector are located on the left side, and the sensor signal plug connector and the vehicle body signal plug connector are located on the right side. Totally, three circular installation lugs are arranged on the left side wall and the right side wall of a bottom plate. The height of the installation lugs is larger than the thickness of the bottom plate. Positioning protrusions extend into positioning grooves so that the bottom plate and the cover plate can be installed and positioned. The high-performance power-assisted steering electronic control box is compact in structure and small in size and effectively eradicates inter-wire interference produced in the assembling.

Description

technical field [0001] The invention relates to a power steering electric control box used in automobiles, belonging to the technical field of mechanical structures. Background technique [0002] The power steering electric control box is an essential part of the electric power steering control system, which consists of a circuit board, a bottom plate, a cover plate and a connector. The cover plate and the bottom plate together form an electric control box shell, and the circuit board is installed on the bottom plate and located in the electric control box shell. The connectors are installed on the side wall of the cover, the connectors are all upright, and the whole electric control box housing is a standard square housing. [0003] The main problem of this structure is: due to the different sizes of the connectors, the size of the motor power connector is higher than that of the sensor signal connector, the body power connector and the body signal connector. To meet the ...

Problems solved by technology

[0003] The main problem of this structure is: due to the different sizes of the connectors, the size of the motor power connector is higher than that of the sensor signal connector, the body power connector and the body signal connector. To meet the installation requirements of the motor power connector, the height should be increased accordingly to match the connector, so that the entire electric control box looks huge and brings a lot of trouble to the installation and layout, especially in the case of limited space. can't install at all

At the same time, each connector is set separately. When the main engine factory assembles the assembly, it often produces inter-line interference, which affects the assembly efficiency.
