Drawings

The following detailed description of embodiments of the invention is provided in conjunction with the accompanying drawings, in which:

Fig. 1 is an exploded view of an embodiment of a fixing structure of a PCB of the present invention;

Fig. 2 is a schematic structural diagram of an embodiment of the fixing bracket according to the present invention.

Detailed Description

as shown in fig. 1 and 2, a fixing structure of a PCB includes a housing 100 and a fixing bracket 200 for mounting the PCB, wherein the housing 100 includes a storage cavity, and the fixing bracket 200 is detachably mounted in the storage cavity. By installing the PCB on the fixing bracket 200, the operable space of the fixing bracket 200 is large, the PCB is easier to be mounted on the fixing bracket 200, and then the fixing bracket 200 is installed on the housing 100, and the fixing bracket 200 can be designed to have an installation structure adapted to the housing 100, thereby ensuring the installation firmness and improving the installation convenience. The PCB may be fixed to the fixing bracket 200 by riveting, screwing or clipping. The fixing bracket 200 can be fixed in the storage cavity in a threaded connection or a clamping connection manner.

further, the casing 100 is provided with two bosses 101 connected with the fixing bracket 200 in a clamping manner, and the two bosses 101 are respectively arranged on two side walls opposite to the storage cavity. Two are set up respectively in the both sides of fixed bolster 200 for fixed bolster 200 obtains fully spacing, has improved fixed stationarity.

Further, the fixing bracket 200 includes a body and two fixture blocks 201, the body is used for mounting a PCB, the fixture blocks are used for being connected with the boss 101 in a matching manner, the two fixture blocks 201 are respectively disposed on two opposite sides of the body, and the fixture blocks are provided with openings for accommodating the boss 101. The opening buckle has good elasticity to can set for bigger magnitude of interference in the design, thereby guarantee fixture block and boss 101 cooperation interference all the time, prevent not hard up, guarantee the firm nature of installation.

Further, the edge of the opening of the fixture block is provided with a limiting protrusion 202, and the limiting protrusion 202 is provided with a guide surface for the boss 101 to enter the opening. Through setting up the spigot surface for boss 101 and fixture block assemble more easily, improve the convenience of installation. Through setting up spacing arch 202 for boss 101 is connected more firmly with the fixture block, guarantees the firm nature of installation.

Furthermore, the fixture block is C-shaped, and one end of the fixture block is fixedly connected to the body. One end of the clamping block is fixed on the body to form a cantilever structure, so that the opening buckle has better elasticity.

Further, a guide protrusion 102 is arranged on the bottom surface of the storage cavity, and the fixing bracket 200 is provided with a guide groove 203 matched with the guide protrusion 102. Through the cooperation of the guide protrusion 102 and the guide groove 203, the guide fixing bracket 200 and the housing 100 are better installed and positioned, and the installation convenience is improved. Meanwhile, the PCB board can be provided with a limit groove matched with the guide protrusion 102 to further limit and fix the PCB board.

Furthermore, a positioning protrusion 204 is disposed on the bottom surface of the fixing bracket 200, and a positioning hole matched with the positioning protrusion 204 is disposed on the bottom surface of the storage cavity. After the PCB board and the fixing bracket 200 are pre-assembled, the PCB board is placed in the housing 100, and first, the positioning protrusion 204 guides the PIN (PIN is a metal material for completing electrical conductive transmission) on the PCB board to vertically enter a box insertion hole (the box insertion hole is a through hole for extending the PIN out of the housing 100 and connecting with the outside) of the housing 100 until the fixing bracket 200 and the housing 100 are completely assembled. Different from the conventional PIN needle with an angle and obliquely pressed in, the existing scheme can ensure that the PIN needle is loaded in multiple directions and can also ensure that the PIN needle is not bent.

Further, in an embodiment, a bottom surface of the fixing bracket 200 is provided with a positioning groove for matching with the PCB, and the fixing bracket 200 is provided with a hook 205 for pressing the PCB. The hooks 205 are matched with the positioning grooves to realize the compression and fixation of the PCB in the vertical direction.

Further, in an embodiment, two sets of positioning portions 206 are disposed on the fixing bracket 200, the two sets of positioning portions 206 are disposed on two opposite sides of the PCB respectively, and the two sets of positioning portions 206 complete front-back positioning of the PCB.

The installation method of the fixing structure in the embodiment is as follows: the PCB is mounted on the fixing bracket 200, and is embedded into the guide protrusion 102 of the housing 100 through the guide groove 203 of the fixing bracket 200, and is pushed forward until the positioning protrusion 204 of the fixing bracket 200 enters the positioning hole of the housing 100, and then the opening of the fixture block of the fixing bracket 200 is embedded into the boss 101 of the housing 100 to be matched and fixed, so that the mounting is completed.

The vehicle lamp of the embodiment of the scheme comprises the fixing structure. Other components of the vehicle lamp are well known to those skilled in the art and will not be described in detail herein.

The automobile comprises the automobile lamp. Other components of the vehicle are well known to those skilled in the art and will not be described in detail herein.

The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
