Description

Technical Field

[0001] The utility model belongs to the field of automobiles and relates to an ECU assembly. Background Technique

[0002] The existing ECU housing is mainly connected to the connection bracket through two assembly methods. One assembly method is that the clamping piece deforms outwards and the buckle does not deform. Since it is difficult for the clamping piece to deform, the assembly force is too large and it is not convenient for installation. The other is to set buckles by opening holes on the outer wall of the ECU housing. During the assembly process, the buckle deforms inwards and the clamping piece basically does not deform. Since the buckle is easy to deform, the second assembly method requires less assembly force. However, by the inward deformation of the buckle, space for the buckle to deform needs to be reserved, resulting in a reduction in the space for placing the PCBA (Printed Circuit Board Assembly), which is not conducive to the arrangement of components. Moreover, there are gaps around the buckle, which is not conducive to the ECU meeting the functions of dust and water protection. These two assembly methods both have disadvantages, leading to problems that the ECU is not convenient for installation and does not have a waterproof function. Therefore, we need to design an ECU assembly with the advantages of convenient installation and waterproof function. Summary of the Invention

It is characterized in that a mounting housing is detachably arranged at the front end of the assembly housing, a fixing part is fixedly arranged on the assembly housing at a position relative to the mounting housing, a mounting groove for fixing the mounting housing is opened on the fixing part, a connecting part is arranged on the mounting housing at a position relative to the fixing part, a positioning part that extends into the mounting groove and is positioned is fixedly arranged on the connecting part, a positioning component for positioning the positioning part on the mounting housing is arranged in the fixing part, the positioning component is composed of a positioning rod, a sliding part and a return spring, a positioning hole that fits the positioning rod is opened on the positioning part, one end of the positioning rod extends out of the fixing part and is connected with a lifting part, the other end of the positioning rod telescopically moves in the fixing part to control the positioning of the positioning part, a slot for installing the sliding part and the return spring is opened on the inner wall of the fixing part, and the sliding part slides in the slot. A sealing strip is arranged in the assembly housing, and a sealing groove that fits the sealing strip is opened on the mounting housing.

[0005] In the above-mentioned ECU assembly, the connecting part is arranged in an L-shaped structure, and the connecting part and the mounting housing are integrally formed.

[0006] In the above-mentioned ECU assembly, there are two fixing parts, which are respectively arranged on the left and right sides of the assembly housing and are integrally formed with the assembly housing.

[0007] In the above-mentioned ECU assembly, four mounting seats for installation are integrally arranged at the lower end of the assembly housing.
