Description

Technical Field

[0001] This utility model relates to the electrical field, and in particular to a flexible circuit board mounting structure and electronic equipment. Background Technology

[0002] like Figure 1 As shown, in the prior art, when mounting the flexible circuit board 10' onto two mounting members 20', a bending area formed by bending needs to be reserved on the flexible circuit board 10'. This bending area can act as a buffer to compensate for the positional error between the two mounting members 20'. The above design has the following disadvantages: 1. The bending area is suspended, has low strength, and is easily damaged or even broken when subjected to impact and vibration; 2. When manufacturing the flexible circuit board 10', a special jig is required to bend the flexible circuit board 10' to form the bending area, which increases the manufacturing cost of the flexible circuit board 10'; 3. The bending area increases the overall area of ​​the flexible circuit board 10', increasing the manufacturing cost of the flexible circuit board 10'. Utility Model Content

[0003] The purpose of this invention is to provide a flexible circuit board mounting structure that does not require a pre-reserved bending area on the flexible circuit board, as well as an electronic device including the same.

[0004] To achieve the above objectives, this utility model provides a flexible circuit board mounting structure, which includes a mounting component, a flexible circuit board, and a connecting structure connecting the mounting component and the flexible circuit board. The connecting structure includes a connection port formed on the flexible circuit board and a connecting post formed on the mounting component. The connection port includes a hole-shaped portion and a groove-shaped portion. The groove-shaped portion communicates with the hole-shaped portion and extends in the radial direction of the hole-shaped portion. The connecting post passes through the flexible circuit board through the connection port.

[0005] As a further improvement of this utility model, multiple groove-shaped portions are provided, and the multiple groove-shaped portions are arranged along the circumferential direction of the hole-shaped portion, with a petal-shaped portion formed between two adjacent groove-shaped portions.

[0006] As a further improvement of this utility model, the diameter of the hole is not less than the diameter of the connecting post, and the connecting post is disposed through the hole.

[0007] As a further improvement of this utility model, the mounting component includes a first mounting component and a second mounting component, and the connection structure includes a first connection structure connecting the first mounting component and the flexible circuit board, and a second connection structure connecting the second mounting component and the flexible circuit board.

[0008] As a further improvement of this utility model, the first mounting member and the second mounting member are arranged along the first direction, and four groove-shaped portions are provided in one of the connection ports. Among the four groove-shaped portions of the same connection port, two extend along the first direction, and the other two extend along the second direction perpendicular to the first direction.

[0009] As a further improvement of this utility model, the flexible circuit board includes a groove wall surrounding the groove-shaped portion, the groove wall including a first side and a second side arranged at an angle, and a transition surface connecting the first side and the second side, the transition surface extending in an arc shape.

[0010] As a further improvement of this utility model, the groove-shaped portion is square, the first side is located on the side of the groove-shaped portion away from the hole-shaped portion, and the second side extends from the hole-shaped portion to the first side.

[0011] As a further improvement of this utility model, the flexible circuit board mounting structure further includes a plate-shaped member, which is connected to the side of the flexible circuit board near the mounting member, and has a limiting hole thereon. The connecting post passes through the limiting hole, and the diameter of the limiting hole is larger than the diameter of the connecting post.

[0012] As a further improvement of this utility model, the extension length of the groove-shaped portion is 1 / 3 to 1 / 2 of the diameter of the hole-shaped portion.

[0013] This invention also provides an electronic device, which includes the above-described flexible circuit board mounting structure.

[0014] Beneficial effects:

[0015] In the flexible circuit board mounting structure and electronic device provided by this utility model, the flexible circuit board near the groove and hole can be curled and deformed, so that the relative position between the connecting post and the flexible circuit board can be changed. Thus, when the flexible circuit board is connected to the mounting component, the connecting structure can compensate for the positional error between the flexible circuit board and the mounting component. In the flexible circuit board mounting structure, the flexible circuit board is flat and has a small overall area, so there is no need to reserve a bending area. When subjected to impact and vibration, the flexible circuit board is not easily damaged, and the manufacturing cost of the flexible circuit board is low. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0029] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0030] One embodiment of the present invention provides an electronic device, which includes a flexible circuit board mounting structure.

[0031] like Figure 2-6 As shown, the flexible circuit board mounting structure 100 includes a mounting component 10, a flexible circuit board 20, and a connecting structure 30 connecting the mounting component 10 and the flexible circuit board 20.

[0032] The connection structure 30 includes a connection port 31 formed on the flexible circuit board 20 and a connection post 32 formed on the mounting member 10. The connection port 31 passes through the flexible circuit board 20 and includes a hole-shaped portion 311 and a groove-shaped portion 312. The groove-shaped portion 312 communicates with the hole-shaped portion 311 and extends in the radial direction of the hole-shaped portion 311. The connection post 32 is disposed through the connection port 31 and passes through the flexible circuit board 20.

[0033] The connecting post 32 is inserted into the hole 311, and the flexible circuit board 20 can be flexibly deformed. The aforementioned groove 312 and hole 311 allow the portion of the flexible circuit board 20 near the groove 312 and hole 311 to curl and deform, thereby changing the relative position between the connecting post 32 and the flexible circuit board 20. Thus, when the flexible circuit board 20 is connected to the mounting member 10, the connecting structure 30 can compensate for the positional error between the flexible circuit board 20 and the mounting member 10.

[0034] Regarding the aforementioned positional error, it should be noted that when the positional error is zero, it means that the actual relative positional relationship between the mounting component 10 and the flexible circuit board 20 conforms to the pre-designed relative positional relationship. However, in actual installation, the actual position of the mounting component 10 will deviate slightly from the pre-designed position. Therefore, there will be a positional error between the flexible circuit board 20 and the mounting component 10.

[0035] In this embodiment, multiple slotted portions 312 are provided, arranged along the circumferential direction of the hole-shaped portion 311. A petal-shaped portion 22 is formed between adjacent slotted portions 312. The petal-shaped portion 22 can be rolled and deformed, allowing the relative position between the connecting post 32 and the flexible circuit board 20 to change. By providing multiple slotted portions 312, the relative position between the connecting post 32 and the flexible circuit board 20 can be changed in multiple directions, thereby compensating for positional errors between the flexible circuit board 20 and the mounting member 10 in multiple directions. The multiple slotted portions 312 are uniformly arranged along the circumferential direction of the hole-shaped portion 311.

[0036] In this embodiment, the diameter of the hole 311 is not less than the diameter of the connecting post 32, and the connecting post 32 can pass through the hole 311. When the positional error between the mounting member 10 and the flexible circuit board 20 is zero, the connecting post 32 is exactly inside the hole 311, and the aforementioned petal-shaped portion 22 will not deform. As a preferred embodiment, the diameter of the hole 311 can be directly equal to the diameter of the connecting post 32.

[0037] In other embodiments, the diameter of the hole 311 may be smaller than the diameter of the connecting post 32. In this way, even if the positional error between the mounting member 10 and the flexible circuit board 20 is zero, the aforementioned petal-shaped portion 22 will still curl when the connecting post 32 passes through the flexible circuit board 20.

[0038] In this embodiment, two mounting members 10 are provided, and the flexible circuit board 20 is mounted on the two mounting members 10. The two mounting members 10 are a first mounting member 10a and a second mounting member 10b, respectively. Correspondingly, the connecting structure 30 includes a first connecting structure 30a connecting the first mounting member 10a and the flexible circuit board 20, and a second connecting structure 30b connecting the second mounting member 10b and the flexible circuit board 20. When the flexible circuit board 20 is connected to the first mounting member 10 and the second mounting member 10, it is flat and will not curl.

[0039] With the above configuration, the position of the flexible circuit board 20 can be changed relative to both the first mounting member 10a and the second mounting member 10b, and both the first connecting structure 30a and the second connecting structure 30b can compensate for the positional error between the first mounting member 10a and the second mounting member 10b.

[0040] As can be imagined, both the first connecting structure 30 and the second connecting structure 30 include a connecting port 31 and a connecting post 32, wherein the connecting post 32 of the first connecting structure 30 is formed on the first mounting member 10, and the connecting post 32 of the second connecting structure 30 is formed on the second mounting member 10.

[0041] Furthermore, the first mounting member 10a and the second mounting member 10b are arranged along a first direction. A connection port 31 has four slotted portions 312. Of the four slotted portions 312 in the same connection port 31, two extend along the first direction, and the other two extend along a second direction perpendicular to the first direction, forming a cross shape. With this configuration, when the flexible circuit board 20 is connected to the first mounting member 10a and the second mounting member 10b, the connection structure 30 can compensate for errors in the first and second mounting members 10a and 10b in both the first and second directions.

[0042] In other embodiments, the slot-shaped portion 312 may be provided with one, three or more, and the flexible circuit board 20 may be connected to three, four or more mounting members 10. The number of slot-shaped portions 312 and the specific number of mounting members 10 are not particularly limited.

[0043] In other embodiments, the following configuration may also be made: one of the first mounting member 10a and the second mounting member 10b is connected to the flexible circuit board 20 through the connection structure 30, and the other is fixedly connected to the flexible circuit board 20, that is, the positional error between the first mounting member 10a and the second mounting member 10b is compensated by only one connection structure 30.

[0044] The flexible circuit board 20 includes a groove wall 21 surrounding a groove-shaped portion 312. The groove wall 21 includes a first side surface 211 and a second side surface 212 arranged at an angle, and a transition surface 213 connecting the first side surface 211 and the second side surface 212. The transition surface 213 extends in an arc shape. When the portion of the flexible circuit board 20 near the groove-shaped portion 312 and the hole-shaped portion 311 curls and deforms, the transition surface 213 can reduce stress concentration and prevent the flexible circuit board 20 from tearing at the junction of the first side surface 211 and the second side surface 212.

[0045] Furthermore, the groove-shaped portion 312 is square, with the first side surface 211 located on the side of the groove-shaped portion 312 away from the hole-shaped portion 311, and the second side surface 212 extending from the hole-shaped portion 311 to the first side surface 211. Two second side surfaces 212 are provided in the same groove-shaped portion 312, and the two second side surfaces 212 are arranged opposite to each other. Two transition surfaces 213 are also provided, and the two transition surfaces 213 respectively transitionally connect the first side surface 211 and the two second side surfaces 212.

[0046] In this embodiment, the flexible circuit board mounting structure 100 further includes a plate-shaped member 40, which is connected to the side of the flexible circuit board 20 near the mounting member 10, and has a limiting hole 41 thereon. The connecting post 32 passes through the limiting hole 41, and the diameter of the limiting hole 41 is larger than the diameter of the connecting post 32.

[0047] With the above configuration, when the flexible circuit board 20 moves relative to the mounting member 10, if the wall of the limiting hole 41 contacts the connecting post 32, the flexible circuit board 20 cannot continue to move relative to the mounting member 10. In this way, the plate-shaped member limits the movable range of the flexible circuit board 20 relative to the mounting member 10, thus protecting the flexible circuit board 20.

[0048] As a preferred embodiment, the radius of the limiting hole 41 is not less than the radius of the hole-shaped portion 311 plus the length of the groove-shaped portion 312 extending radially along the hole-shaped portion 311. In this way, the groove-shaped portion 312 can fully perform its function of deforming part of the flexible circuit board 20 without being restricted by the plate-shaped member 40. When the radius of the limiting hole 41 is not less than the radius of the hole-shaped portion 311 plus the length of the groove-shaped portion 312 extending radially along the hole-shaped portion 311, the plate-shaped member 40 can also be connected to the side of the flexible circuit board 20 opposite to the mounting member 10.

[0049] As can be imagined, this embodiment includes two plate-shaped members 40. One of the plate-shaped members 40 has a limiting hole 41 through which the connecting post 32 on the first mounting member 10 passes, and the other has a limiting hole 41 through which the connecting post 32 on the second mounting member 10 passes.

[0050] In this embodiment, the extension length of the groove portion 312 is 1 / 3 to 1 / 2 of the diameter of the hole portion 311. In this way, the movable distance of the flexible circuit board 20 relative to the mounting member 10 can be kept within a reasonable range. This range is not too small, so as not to effectively compensate for the positional error between the mounting member 10 and the flexible circuit board 20, nor too large, so as not to affect the strength of the flexible circuit board 20.

[0051] In summary, in the flexible circuit board mounting structure 100 provided by this utility model, the portion of the flexible circuit board 20 near the groove-shaped portion 312 and the hole-shaped portion 311 can be curled and deformed, so that the relative position between the connecting post 32 and the flexible circuit board 20 can be changed. Thus, when the flexible circuit board 20 is connected to the mounting member 10, the connecting structure 30 can compensate for the positional error between the flexible circuit board 20 and the mounting member 10. In the flexible circuit board 20 mounting structure, the flexible circuit board 20 is flat and has a small overall area, so there is no need to reserve a bending area. When subjected to impact and vibration, the flexible circuit board 20 is not easily damaged, and the manufacturing cost of the flexible circuit board 20 is low.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
