[0034] Reference Figures 1 to 3 and Figure 7 According to an embodiment of the first aspect of the utility model, a PCB board installation structure with an inclined surface includes a shell 100, a mounting bracket 200 and a PCB board 300. The shell 100 is integrally injection molded, and the shell 100 has a first shell plate 110. The first shell plate 110 is provided with a mounting connection column 120. The mounting connection column 120 is extended along the demoulding direction of the shell 100. The thickness direction of the first shell plate 110 and the demoulding direction have an angle. The mounting bracket 200 has a first connecting portion 210 and a second connecting portion 220. The second connecting portion 220 can be connected to the mounting connection column 120 by a fastener. The PCB board 300 is installed on the mounting bracket 200. The first connecting portion 210 can be matched with the PCB board 300 to make the PCB board 300 and the first shell plate 110 arranged parallel. By providing the mounting bracket 200, the PCB board 300 and the first shell plate 110 can be connected to the mounting bracket 200 respectively by using the first connecting portion 210 and the second connecting portion 220, and the mounting bracket 200 can be connected to the mounting connecting column 120 through the second connecting portion 220, so that the mounting bracket 200 is arranged on the first shell plate 110, and the PCB board 300 can be connected to the mounting bracket 200 through the first connecting portion 210, so that it can be arranged parallel to the first shell plate 110. Even when the mounting connecting column 120 is restricted by demolding, the PCB board 300 can be indirectly arranged parallel to the first shell plate 110 through the mounting bracket 200, so that the internal space of the shell 100 can be fully utilized.

[0035] Specifically, the shell 100 is integrally formed by injection molding, so the shell 100 needs to be demolded from the mold. Generally, the shell 100 is square in shape, which is convenient for demolding. However, when the shell 100 has multiple inclined surfaces, the internal connection structure needs to consider the demolding problem. The first shell plate 110 can be one of the inclined surfaces, and a mounting connection column 120 is provided on it. In order to facilitate demolding, the mounting connection column 120 can only be extended in the direction of demolding. The mounting connection column 120 can be a hollow column to facilitate screwing in. The first shell plate 110 is inclined relative to other plates, so there is an angle between the axial direction of the mounting connection column 120 and the thickness direction of the first shell plate 110. The mounting bracket 200 has a second connecting portion 220, and the second connecting portion 220 can be connected to the mounting connection column 120 by a fastener. The fastener can be a screw. The second connecting portion 220 can be aligned with the mounting connection column 120, and the screw can press the second connecting portion 220 tightly against the mounting connection column 120. At this time, the mounting bracket 200 can be arranged parallel to the first shell plate 110, and then the PCB board 300 can be connected with the first connecting portion 210. The specific connection method can be snap connection, fastener connection or abutment. The specific connection method is not limited. The first connecting portion 210 can enable the PCB board 300 to be installed on the mounting bracket 200 that is arranged parallel to the first shell plate 110, so that the PCB board 300 can be arranged parallel to the first shell plate 110. By setting the mounting bracket 200, the effect of installing the PCB board 300 parallel to the first shell plate 110 can be indirectly satisfied, thereby making way for the space inside the shell 100, and then making full use of the space inside the shell 100 to set other components.

[0043] Specifically, the second connecting portion 220 can be a connecting column, which is parallel to the installation connecting column 120. The connecting column can have a third mounting hole 221 extending in its length direction. The fastener can be a screw. During installation, the screw can pass through the third mounting hole 221 and then be threadedly connected to the installation connecting column 120. The screw can press the second connecting portion 220 against the installation connecting column 120, thereby realizing the fastening connection of the mounting bracket 200 on the first shell plate 110.

[0044] It is understandable that the second connection portion 220 may also be a mounting slot, and the mounting connection column 120 may be snap-connected to the mounting slot.
