Description

Assembling structures and electronic devices

The present invention relates to an assembly structure, and in particular to an assembly structure and an electronic device used for assembling two circuit boards.

During the assembly process of electronic devices, such as laptops, the camera module is generally placed on the top side of the display screen, and the camera module and the connected cable are connected through two corresponding connectors as a signal transmission method. However, these two connected connectors are vertically overlapped, relying only on the pin structure in the slot as the mutual support force. Therefore, the connector often rebounds and loosens, causing the camera to lose its function.

The existing solution is to use additional auxiliary materials (such as tape) to bind the connectors after they are butted and assembled to avoid springing back or loosening. However, this method not only increases the cost of auxiliary materials, manpower stations and assembly hours, but also risks exposure of auxiliary materials to the casing after the entire machine is assembled.

In view of the above-mentioned issues, the purpose of the present invention is to provide an assembly structure and an electronic device having the assembly structure, which can prevent the connector from rebounding and loosening, and can also avoid the problems caused by the existing use of auxiliary materials to wrap and bind the connector.

To achieve the above object, the present invention proposes an assembly structure including a first circuit board, a second circuit board and a sliding pressing member. The second circuit board is adapted to be connected to the first circuit board, and the second circuit board includes a top surface. The sliding pressing part is slidably disposed on the first circuit board; when the second circuit board is connected to the first circuit board, the sliding pressing part is adapted to slide to the top surface of the second circuit board to press the second circuit board with the first circuit board.

In one embodiment, the sliding pressing member includes a pressing portion, and the pressing portion contacts the top surface of the second circuit board.

In one embodiment, the first circuit board includes a first connector, the second circuit board includes a second connector corresponding to the first connector, and the pressing position of the pressing portion corresponds to the connection between the first connector and the second connector.

In one embodiment, the press-fit portion has a notch.

In one embodiment, in a direction perpendicular to the top surface of the second circuit board, the distance between the pressing portion and the first circuit board is substantially equal to the distance between the top surface and the first circuit board.

In one embodiment, the first circuit board further includes a guide groove, and the sliding press-fitting member further includes a penetration portion, one end of the penetration portion is connected to the press-fitting portion, and the penetration portion passes through the guide groove and can move relative to the guide groove.

In one embodiment, opposite sides of the guide groove each have a bent portion.

In one embodiment, the sliding press-fit part further includes an extension portion, which is connected to the other end of the penetration portion.

In one embodiment, the pressing portion and the extending portion extend in opposite directions from two ends of the through portion.

To achieve the above-mentioned purpose, the present invention also proposes an electronic device including the aforementioned assembly structure.

As mentioned above, in the assembly structure and electronic device of the present invention, the sliding press fitting is slidably arranged on the first circuit board, and when the second circuit board is connected to the first circuit board, the sliding press fitting is suitable for sliding to the top surface of the second circuit board to press the second circuit board and the first circuit board. The assembly structure and electronic device of the present invention can solve the problem of the connector rebounding and loosening of the two circuit boards. In addition, since the present invention does not need to use additional auxiliary materials (such as tape) to fix the connector, the operation method is also quite simple. Therefore, in addition to avoiding the problems caused by the existing use of auxiliary materials to bundle and bind the connector, it can also achieve the purpose of saving production line personnel hours and additional workstation settings.

FIG. 1 is a partial schematic diagram of an electronic device 2 of an embodiment of the present invention, FIG. 2A is an exploded schematic diagram of an assembly structure 1 of the electronic device 2 of FIG. 1 , FIG. 2B and FIG. 2C are respectively combined schematic diagrams of the assembly structure 1 of FIG. 2A , and FIG. 2D and FIG. 2E are respectively side schematic diagrams of the assembly structure 1 of FIG. 2B and FIG. 2C . Here, the sliding press member 13 of the assembly structure 1 of FIG. 2B is in an open position (i.e., the sliding press member 13 is in an open state), and the sliding press member 13 of the assembly structure 1 of FIG. 2C is in a closed position (i.e., the sliding press member 13 is in a closed state).

Please refer to Figures 1, 2A to 2E. The electronic device 2 of this embodiment includes an assembly structure 1. The assembly structure 1 can be located on the side of the display screen of the electronic device 2, and can include a first circuit board 11, a second circuit board 12, and a sliding press member 13.

The second circuit board 12 is suitable for connecting to the first circuit board 11, and the second circuit board 12 includes a top surface 121. The first circuit board 11 can be a printed circuit board (PCB) or a flexible circuit board. The first circuit board 11 of this embodiment is, for example but not limited to, a camera module of a laptop computer, and is a printed circuit board, and the second circuit board 12 is a flexible printed circuit board (FPC) as an example. First of all, it is explained that in this article, the direction perpendicular to the top surface 121 of the second circuit board 12 is the first direction D1, and the extension direction of the first circuit board 11 is the second direction D2, and the second direction D2 is substantially perpendicular to the first direction D1.

The first circuit board 11 includes a first connector C1, and the second circuit board 12 includes a second connector C2 corresponding to the first connector C1. The first connector C1 and the second connector C2 have corresponding electrical connection terminals, and the first circuit board 11 and the second circuit board 12 can be connected to each other through the corresponding first connector C1 and the second connector C2, The second circuit board 12 and the first circuit board 11 can transmit electrical signals. Here, the second connector C2 and the top surface 121 can be located on opposite sides of the second circuit board 12 respectively, and when the second circuit board 12 is connected to the first circuit board 11, the top surface 121 is far away from the second circuit board 12. The upper surface of the first circuit board 11 is shown in Figure 2C and Figure 2E.

The sliding pressing member 13 is slidably disposed on the first circuit board 11, and when the second circuit board 12 is connected to the first circuit board 11, the sliding pressing member 13 is suitable for sliding to the top surface 121 of the second circuit board 12. The second circuit board 12 and the first circuit board 11 are pressed together. Please refer to FIG. 2B . When the second circuit board 12 is connected to the first circuit board 11 and the sliding pressing member 13 has not yet slid to the top surface 121 of the second circuit board 12 , the sliding pressing member 13 is in the open position. Please refer to FIG. 2C . When the second circuit board 12 is connected to the first circuit board 11 and the sliding pressing member 13 slides to the top surface 121 of the second circuit board 12 , the sliding pressing member 13 is in the closed position.

Specifically, the sliding pressing part 13 of this embodiment may include a pressing part 131, at least one through part 132 and at least one extending part 133. One end of the through part 132 is connected to the pressing part 131, and the other end of the through part 132 is connected to the pressing part 131. Connect extension 133. Here, the sliding pressing part 13 has a pressing part 131, two through parts 132 and two extending parts 133. The two through parts 132 are respectively connected to both sides of the same side of the pressing part 131, and each through part 132 is connected correspondingly. Each extension part 133 is taken as an example. Among them, the pressing part 131 is substantially perpendicular to the penetration part 132, and the extension part 133 is also substantially perpendicular to the penetration part 132. However, it is not limited thereto. In different embodiments, the relationship between the pressing part 131 and the penetration part 132 is The through portion 132 and the extension portion 133 do not have to be perpendicular, for example, the angle between them is greater than 90 degrees. In addition, the extending directions of the pressing portion 131 and the two extending portions 133 are substantially parallel to the second direction D2, and the pressing portion 131 and the two extending portions 133 extend in opposite directions from both ends of the through portion 132.

In addition, the first circuit board 11 of the present embodiment may further include a guide groove 111, which connects the upper and lower surfaces of the first circuit board 11, and the penetration portion 132 of the sliding press-fitting member 13 passes through the guide groove 111 and can move relative to the guide groove 111. Here, the guide groove 111 is used to guide and limit the movement stroke of the sliding press-fitting member 13 (penetration portion 132). The first circuit board 11 of the present embodiment is an example in which two guide grooves 111 are provided, and each penetration portion 132 passes through each guide groove 111 and can move in the guide groove 111.

Therefore, when the second connector C2 of the second circuit board 12 is connected to the first connector C1 of the first circuit board 11, the assembler can push the pressing portion 131 of the sliding pressing member 13 from the open position (FIG. 2B, FIG. 2D) to move toward the second circuit board 12. Since the guide groove 111 guides and limits the movement of the penetration portion 132, the pressing portion 131 can move to the top surface 121 of the second circuit board 12 and press the second circuit board 12 (i.e., the closed position, as shown in FIG. 2C, FIG. 2E). At this time, the pressing position of the pressing portion 131 corresponds to the connection between the first connector C1 and the second connector C2, so the problem of rebound or loosening of the second circuit board 12 can be avoided. Here, in the direction perpendicular to the top surface 121 of the second circuit board 12 (i.e., the first direction D1), the distance d1 between the pressing portion 131 and the first circuit board 11 may be substantially equal to the distance d2 between the top surface 121 and the first circuit board 11. In some embodiments, the distance d1 may even be slightly smaller than the distance d2 to provide a greater downward pressing force.

It is worth mentioning that, please refer to FIG. 2B and FIG. 2D again. The pressing part 131 of this embodiment has a notch U on the side away from the second circuit board 12. The notch U allows the sliding pressing member 13 to avoid being located on the second circuit board 12. Electronic components 112 on a circuit board 11 to avoid component or mechanism interference. In addition, each guide groove 111 in this embodiment has a bending portion 113 on opposite sides respectively. When the sliding pressing member 13 moves from the starting position (or open position) in FIG. 2B to the top of the second circuit board 12 When the surface 121 is on (closed position), each through-portion 132 can produce a frustrating feeling when passing through each bending portion 113, which is helpful for the assembler to truly feel the opening and closing state when operating the sliding pressing member 13.

As mentioned above, in the assembly structure 1 and the electronic device 2 of the present embodiment, the sliding press-fitting member 13 is slidably disposed on the first circuit board 11, and when the second circuit board 12 is connected to the first circuit board 11, the sliding press-fitting member 13 is suitable for sliding onto the top surface 121 of the second circuit board 12 to press the second circuit board 12 and the first circuit board 11. The structural design allows the assembly structure 1 of the present embodiment to solve the problem of connector rebound and loosening. In addition, since no additional auxiliary materials (such as tape) are required to fix the connector, the operation method is also quite simple. It can be completed by sliding the sliding press member 13 onto the top surface 121 of the second circuit board 12. Therefore, in addition to avoiding the problems caused by the existing use of auxiliary materials to bundle and constrain the connector, it can also achieve the purpose of saving production line personnel hours and additional workstation settings.

Finally, in order to avoid interfering with the normal operation of the first circuit board 11 and/or the second circuit board 12, the sliding press-fitting part 13 can be made of a non-magnetic or weakly magnetic metal material, such as but not limited to tinplate or 301 stainless steel. In different embodiments, the sliding press-fitting part 13 can also be a non-metal product, such as a plastic product, which is not limited by the present invention.

In summary, in the assembly structure and electronic device of the present invention, the sliding press fitting is slidably arranged on the first circuit board, and when the second circuit board is connected to the first circuit board, the sliding press fitting is suitable for sliding to the top surface of the second circuit board to press the second circuit board and the first circuit board. The assembly structure and electronic device of the present invention can solve the problem of the connector rebounding and loosening of the two circuit boards. In addition, since the present invention does not need to use additional auxiliary materials (such as tape) to fix the connector, the operation method is also quite simple. Therefore, in addition to avoiding the problems caused by the existing use of auxiliary materials to bundle and bind the connector, it can also achieve the purpose of saving production line personnel hours and additional workstation settings.
