Problems solved by technology

The traditional method of using the joint arm to clamp the sub-board cannot effectively fix the sub-board during the drop test, causing the sub-board to move relative to the main board, or the sub-board may become loose; even the user accidentally bumps the electronic device. When installed, the daughter board is also moved relative to the main board
As a result, the electrical function of the product is not normal, or the product is damaged, which reduces the product yield
In order to solve the above problems, the industry currently proposes a way to use glue to fix the sub-board. However, there are still disadvantages such as the amount of glue is not easy to control, the quality of glue application is not easy to control, and the cost is increased.

[0048] In the electronic device according to the first embodiment of the present invention, the sub-board is fixed on the main board by a fixing structure. Please refer to Figure 2A and Figure 2B , FIG. 2A shows a perspective view of an electronic device according to a first embodiment of the present invention; Figure 2B A cross-sectional view along line A-A' in Fig. 2A is shown. The electronic device 200 includes a main board 220 , a sub-board 240 , a fixing structure 260 and a casing 280 . The main board 220 , the sub-board 240 and the fixing structure 260 are all disposed in the casing 280 . The motherboard 220 has a connection slot 222 . The sub-board 240 has a first side 241 inserted into the connection slot 222 , and the sub-board 240 is substantially parallel to the main board 220 . The fixing structure 260 includes at least one positioning pin 262 vertically disposed on the main board 220 and contacting a side wall of the sub-board 240 to limit the movement of the ...

[0054] The difference between this embodiment and the above-mentioned fixing structure and the electronic device using it according to the first embodiment of the present invention lies in the position where the positioning bolt contacts the side wall of the sub-board. In addition, the same reference numerals are used for the same components, and the rest of the same parts will be omitted below.

[0055] Please refer to Figure 4A and Figure 4B , FIG. 4A shows a perspective view of an electronic device according to a second embodiment of the present invention; Figure 4B A cross-sectional view along line C-C' in FIG. 4A is shown. The electronic device 200' includes a main board 220, a sub-board 240', a fixing structure 260 and a housing 280. Compared with the sub-board 240 (shown in FIG. 2A ) of the above-mentioned first embodiment, the sub-board 240' in this embodiment further has at least one positioning hole 246'. The number of the positioning holes 246' preferably corre...

Abstract

The invention discloses a fixed structure and electronic equipment applied to the fixed structure for fastening a daughter board with a first side. The fixed structure comprises a main board and at least a location bolt. The main board is provided with a connection slot which is inserted by the first side and the daughter board is parallel with the main board actually. The location bolt is vertically arranged on the main board and in contact with the side wall of the daughter for limiting the movement of the daughter board relative to the main board.

Description

technical field [0001] The invention relates to a fixing structure and an electronic device using the same, in particular to a fixing structure for fixing a sub-board on a main board and an electronic device using the fixing structure. Background technique [0002] In recent years, with the development of electronic technology, people's daily life is full of various electronic devices, such as mobile phones, notebook computers, wireless access points and so on. Electronic devices are constantly being introduced. In addition to the continuous reduction in volume and weight, the functions are continuously integrated and expanded. However, in the limited space of the electronic device, it is impossible to fully cover all the functions, and it is impossible to provide the electronic device with customized functions according to the needs of users. Therefore, at present, the industry has developed a method of providing connection slots on the motherboard, so that the motherboard...
