Description

A kind of EPS controller

Technical field

The utility model relates to electric boosting steering system fields, and in particular to a kind of EPS controller.

Background technique

The EPS controller of existing market and the connection type of motor are divided into harness connection and integral type connects two kinds, compare It is connected in harness, space and cost more are saved in integral type connection.

In the prior art, the EPS controller of integral type connection is usually that pcb board is placed between motor and mounting base, The connecting terminal opening upwards of connector.

But above-mentioned technical proposal has the following deficiencies: this dress that pcb board is placed between motor and mounting base by (1) The mode of connecing makes the whole height of controller excessively high, does not play section space-efficient effect, is still not easy to install；(2) even The connecting terminal opening upwards of device are connect, dust is easily accumulated and are unfavorable for waterproof.

Therefore, in conclusion existing technical solution still has much room for improvement.

Utility model content

The purpose of the utility model is to overcome drawbacks described above present in background technique or problems, provide a kind of EPS control Device processed, not only occupies little space and is easily installed, and can play the effect of water proof and dust proof.

To reach above-mentioned purpose, the utility model adopts the following technical solution:

A kind of EPS controller (the first technical solution) includes upper cover, pcb board, connector, mounting base and motor；On described Lid, pcb board and mounting base are respectively equipped with first through hole, the second through-hole and third through-hole；The output shaft of the motor sequentially passes through Third through-hole, the second through-hole and first through hole；The mounting base includes affixed each other placing part and attachment part；The attachment part It is affixed with the shell of motor；The placing part is affixed with upper cover and is formed for accommodating accommodating chamber described in the accommodating chamber of pcb board Side is equipped with opening, and the connector and pcb board are affixed, and seals and cooperate with the opening.

Based on the first technical solution, it is additionally provided with the second technical solution, further includes water-proof rubber sleeve in the second technical solution； The connector and the opening are sealed by water-proof rubber sleeve to be cooperated.

Based on first or second technical solution, it is additionally provided with third technical solution, further includes axis in third technical solution It holds, the bearing is set to the first through hole, for supporting the output shaft of the motor.

From the above description of the utility model, it can be seen, compared with the existing technology, what the utility model had is following beneficial Effect:

1, the utility model is by wearing upper cover, pcb board and mounting base on the output shaft with motor, so that controller and motor It is linked together, and the height of EPS controller entirety is consistent with the height of motor, this setting not only reduces the volume of controller just In installation, and save the cost of manufacture.

2, for the utility model by the way that connector to be welded in the side of pcb board, this setting not only can avoid dust accretions in connection Device surface and can avoid water enter inside connector, to achieve the effect that dustproof and waterproof.

4, the utility model cooperates the sealing of the opening of connector and accommodating chamber side by water-proof rubber sleeve, the company of further increasing The waterproof effect of device is connect, the service life for being conducive to extend controller is arranged in this.

5, the utility model is by being set to first through hole for bearing, allowing it to the preferably output shaft of supporting motor and subtracting Friction between few output shaft and first through hole.
