Technical Field

[0001] The utility model relates to the technical field of EPS controllers, in particular to a structure in which multiple types of EPS controllers are integrated into a universal platform. Background Art

[0002] The EPS controller is an electric power steering system controller, which is a power steering system that directly relies on the motor to provide auxiliary torque;

[0003] After searching, the application with patent application number CN202321999229.1 discloses an EPS controller, including: an upper cover, a lower cover, a connecting sleeve, a motor and a PCB board. The lower end of the upper cover is provided with a first storage slot and the upper end of the lower cover is provided with a second storage slot. The lower end of the upper cover is butted with the upper end of the lower cover. The first storage slot and the second storage slot are connected to form a PCB board placement space. The PCB board is arranged in the PCB board placement space. The motor is arranged in the upper cover. The lower end of the upper cover protrudes outward to form an upper extension part. The upper end of the lower cover also protrudes outward to form a lower extension part. The upper extension part corresponds to the lower extension part. The connecting sleeve can detachably wrap the upper extension part and the lower extension part. The connecting sleeve provided in the utility model is directly sleeved on the gap where the upper cover and the lower cover are connected. There is no gap for dust and liquid to enter at the position where the upper cover and the lower cover are connected. Moreover, the connecting sleeve is detachable, which is convenient for subsequent inspection and maintenance.

[0004] The above application documents increase convenience by providing a connecting sleeve. The common practice in the current market is that multiple models of EPS controllers adopt multiple different platform structures. In this case, the research and development cycle is long, the production cost is high, the workload of quality control and management is also large, and the practicality is low.

[0005] Therefore, we propose a structure that integrates multiple models of EPS controllers into a common platform. Utility Model Content

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a structure in which multiple types of EPS controllers are integrated into a universal platform, including a PCBA board as the core of the EPS controller; characterized in that: the PCBA board is mounted on a base plate, and a mounting hole is opened on the base plate;

[0008] The mounting holes are arranged in six groups on the base plate, four groups of the mounting holes are opened on the inner sides of the four corners of the base plate, and the other two groups of the mounting holes are opened at opposite positions in the middle of the base plate;

[0009] The base plate is provided with a square profile matching the specifications of the PCBA board around it, and a mounting boss matching the specifications of the PCBA board is also provided on the base plate.

[0010] Preferably, a positioning pin located outside the mounting hole is fixedly mounted on the base plate;

[0011] Among them, the setting of the locating pins can assist the outer mounting holes to fix the PCBA board thereon, thereby ensuring the installation stability.

[0012] Preferably, the PCBA board is an A-type board, and the A-type board is provided with four groups of A-type hole grooves corresponding to the position specifications of the mounting holes at the four corners of the base plate;

[0013] Among them, the setting of the A-shaped slot hole on the A-shaped plate can adapt to the installation holes at the corresponding positions, so that it can be fixedly installed on the top of the base plate, ensuring the installation adaptation effect.

[0014] Preferably, the PCBA board is a B-type board, and the B-type board is provided with two groups of B-type hole grooves corresponding to the position specifications of the two groups of mounting holes in the middle of the base plate;

[0015] Among them, the setting of the B-type slot hole on the B-type plate can adapt to the installation holes at the corresponding positions, so that it can be fixedly installed on the top of the base plate, ensuring the installation adaptation effect.

[0021] It has the following beneficial effects:

[0022] 1. The multi-model EPS controller is integrated into a universal platform structure. Through the setting of the base plate and the various groups of mounting holes thereon, different types of PCBA boards can be installed on the base plate with mounting holes in different positions according to needs. The design of the base plate realizes platformization. EPS controllers with similar functional performance requirements can share one PCBA board, saving nearly 70% of the workload of repeated design, and can also reduce the number of component material models by nearly 20%. Overall, the R&D cycle is shortened, the production cost is reduced, the quality control items are reduced, and the process content of management work is simplified, which solves the problem that different models of PCBA boards in the existing EPS controller need to be matched with a base plate of corresponding shape, which is heavy in workload and low in practicality;
