[0007] The bracket assembly proposed in the present application is used to install a sensitive component. The bracket assembly includes a first bracket and a second bracket. The second bracket is detachably connected to the first bracket. When the first bracket is connected to the second bracket, the first bracket and the second bracket can jointly install and fix the sensitive component. In the process of installing the bracket assembly and the sensitive component, the operator first installs the sensitive component on the first bracket and the second bracket, and then connects the first bracket to the second bracket so that the first bracket and the second bracket can jointly install and fix the sensitive component, so that the bracket assembly and the sensitive component are connected as one. Afterwards, the operator connects the bracket assembly with the sensitive component installed to the circuit board and installs it on the housing of the sensor.

[0008] Understandably, the bracket in the sensor in the related art is usually an integrated structure, and the user needs to first install the bracket on the sensor housing, and then install the sensitive component on the bracket, and the installation steps are relatively cumbersome. Compared with the bracket with an integrated structure, the bracket assembly proposed in this application is a split structure, which is convenient for the operator to install and fix the sensitive component, and allows the operator to install the bracket assembly on the sensor housing after installing the sensitive component on the bracket assembly, which simplifies the installation steps of the bracket assembly and the sensitive component, reduces the difficulty of disassembling the bracket assembly and the sensitive component, and improves the assembly efficiency of the product.

[0009] Furthermore, in order to install the sensitive component, the present application provides a first mounting groove on the first bracket, and a second mounting groove on the second bracket, and the first mounting groove and the second mounting groove are used to accommodate a part of the sensitive component. Specifically, when the first bracket is connected to the second bracket, the opening of the first accommodating groove faces the second bracket, and the opening of the second accommodating groove faces the first bracket.

In this way, the installation steps of the bracket assembly and the sensitive component are simplified, the difficulty of disassembling the bracket assembly and the sensitive component is reduced, and the assembly efficiency of the product is improved.
