Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.
In a first aspect, embodiments of the present application provide a circuit board assembly 100. Referring to fig. 1, the circuit board assembly 100 includes a flexible circuit board 110, and the flexible circuit board 110 generally needs to be bent due to the requirement of space saving to achieve miniaturization. For example, the flexible circuit board 110 includes a first portion 111 and a second portion 112, and the first portion 111 and the second portion 112 may be disposed at an included angle. Specifically, the first portion 111 has a first plate 1111, the second portion 112 has a second plate 1121, and the first plate 1111 and the second plate 1121 may be located on the same side of the flexible circuit board 110 and form an included angle.
Because the structure of the flexible circuit board 110 is relatively flexible and is easily deformed by collapsing, the circuit board assembly 100 may further include a first reinforcing plate 120 and a second reinforcing plate 130 separately disposed from the first reinforcing plate 120, the first reinforcing plate 120 may be connected to the first portion 111, and the second reinforcing plate 130 may be connected to the second portion 112, so as to enhance the structural strength of the first portion 111 and the second portion 112 through the reinforcing plates, so that the first portion 111 and the second portion 112 are not easily deformed after long-term use. It should be noted that the second reinforcing plate 130 is disposed separately from the first reinforcing plate 120, which means that the second reinforcing plate 130 and the first reinforcing plate 120 are both separately manufactured and formed components, rather than simultaneously forming the second reinforcing plate 130 and the first reinforcing plate 120 which are connected together through an integral forming process.
Specifically, the first reinforcing plate 120 may be connected to the first plate surface 1111, the second reinforcing plate 130 may be connected to the second plate surface 1121, and the first reinforcing plate 120 may be connected to the second reinforcing plate 130. Specifically, please refer to fig. 2, an included angle between the first plate surface 1111 and the second plate surface 1121 can be determined directly by an included angle between the first plate surface 1111 and the second plate surface 1121 through the first surface 121 of the first plate surface 1111 connected to the first reinforcing plate 120 and the fourth surface 131 of the second plate surface 1121 connected to the second reinforcing plate 130, and since the determination of the included angle between the first surface 121 and the fourth surface 131 is lower than the determination of the included angle between the flexible first plate surface 1111 and the second plate surface 1121, the forming difficulty of the included angle between the first plate surface 1111 and the second plate surface 1121 can be reduced, and the accuracy of the setting of the included angle can be improved. The first reinforcing plate 120 and the first plate 1111 and the second reinforcing plate 130 and the second plate 1121 can be connected by a hot pressing method or an adhesive method, or can be integrally formed by an injection molding process. The preparation material of the reinforcing plate can be selected from steel materials and the like.
Further, the first reinforcing plate 120 and/or the second reinforcing plate 130 may be provided with a limiting structure 140, and the first reinforcing plate 120 and the second reinforcing plate 130 may be connected through the limiting structure 140, so as to position the first plate surface 1111 and the second plate surface 1121 at a first included angle. By arranging the limiting structure 140 on the first reinforcing plate 120 and/or the second reinforcing plate 130, please refer to fig. 3, after the first reinforcing plate 120 and the second reinforcing plate 130 are connected to the first plate surface 1111 and the second plate surface 1121 respectively, and then the second reinforcing plate 130 is turned over relative to the first reinforcing plate 120 to connect the second reinforcing plate 130 and the first reinforcing plate 120 via the limiting structure 140, it is possible to achieve that the included angle between the first surface 121 and the fourth surface 131 and the included angle between the first plate surface 1111 and the second plate surface 1121 reach the predetermined first included angle, that is, the arrangement of the limiting structure 140 can limit the turning degree of the second reinforcing plate 130 relative to the first reinforcing plate 120, so that the included angle between the first plate surface 1111 and the second plate surface 1121 is more accurately positioned at the first included angle, and the accuracy of the setting of the included angle is improved.
In some exemplary aspects, referring back to fig. 2, the first reinforcing plate 120 has a first surface 121 connected to the first plate surface 1111, a second surface 122 opposite to the first surface 121, and a third surface 123 connected between the first surface 121 and the second surface 122 and facing the second plate surface 1121, the second reinforcing plate 130 has a fourth surface 131 connected to the second plate surface 1121, a fifth surface 132 opposite to the fourth surface 131, and a sixth surface 133 connected between the fourth surface 131 and the fifth surface 132 and facing the first plate surface 1111, and the third surface 123 and/or the fifth surface 132 may be provided with a limiting structure 140. Because the third surface 123 is the surface of the first reinforcing plate 120 close to the second reinforcing plate 130, and the fifth surface 132 is the surface of the second reinforcing plate 130 close to the first reinforcing plate 120 after being turned over for a certain angle relative to the first reinforcing plate 120, the limiting structures 140 are arranged on the third surface 123 and the fifth surface 132, so that the turning-over amplitude of the second reinforcing plate 130 relative to the first reinforcing plate 120 when the second reinforcing plate 130 is connected by the limiting structures 140 can be reduced, and the connection difficulty is reduced. It should be noted that the limiting structure 140 may also be disposed on other surfaces of the first reinforcing plate 120 and/or other surfaces of the second reinforcing plate 130, which is not limited in the embodiments of the present application.
The stopper structure 140 may include a first protrusion 141. Specifically, the first protrusion 141 may be disposed on the third surface 123, the first protrusion 141 has a seventh surface 1411 facing away from the third surface 123, the seventh surface 1411 may include a first region 1412 facing away from the first plate surface 1111, the first region 1412 may be inclined with respect to the first plate surface 1111, specifically, the first region 1412 may gradually decrease in distance from an end close to the first plate surface 1111 to an end far from the first plate surface 1111, and the sixth surface 133 may abut against the first region 1412 and be attached to the first region 1412. The first protrusion 141 is provided with the first region 1412 inclined with respect to the first plate surface 1111, and the first region 1412 defines the folding range of the second reinforcing plate 130 with respect to the first reinforcing plate 120, so that the structure is simple and the processing cost is low. It is understood that the first protrusion 141 and the first reinforcing plate 120 may be formed as a single body, or may be formed separately and then connected together.
When the first reinforcing plate 120 and the second reinforcing plate 130 are connected via the first region 1412 inclined at the first protrusion 141, the second portion 112 may be disposed at a distance from the first portion 111, or may be directly connected to the first portion 111. When the second portion 112 and the first portion 111 are arranged at an interval, the phenomenon that the circuit between the second portion 112 and the first portion 111 is damaged due to an overlarge folding angle when the second portion 112 is folded relative to the first portion 111 can be avoided, and the yield of the circuit board assembly 100 can be improved. When the second portion 112 is directly connected to the first portion 111, the structure of the circuit board assembly 100 can be made more compact and miniaturized.
Specifically, when the second portion 112 is spaced apart from the first portion 111, the flexible circuit board 110 further includes a third portion 113 connected between the first portion 111 and the second portion 112, the seventh surface 1411 may further include a second region 1413 located on a side of the first region 1412 close to the first plate surface 1111 and connected to the first region 1412, the sixth surface 133 may include a third region 1331 connected to the fourth surface 131 and a fourth region 1332 connected between the third region 1331 and the fifth surface 132, and the fourth region 1332 may abut against the first region 1412 and be attached to the first region 1412, so that a first gap g (see fig. 1) is formed among the third portion 113, the second region 1413, and the third region 1331. By reserving the first gap g, the phenomenon that the circuit and the like between the second part 112 and the first part 111 are damaged due to an overlarge folding angle when the second part 112 is folded relative to the first part 111 can be avoided, and the yield of the circuit board assembly 100 is improved.
Further, referring to fig. 1 and fig. 2, a first connecting member 150 may be disposed in the first gap g, and the first connecting member 150 is disposed in the first gap g, so that the first reinforcing plate 120, the second reinforcing plate 130 and the flexible circuit board 110 can be connected to each other, and the first connecting member 150 is disposed to shape the third portion 113 into a predetermined shape and prevent dust from falling into the third portion.
The third portion 113 may have a third plate surface 1131 connected between the first plate surface 1111 and the second plate surface 1121, and in some exemplary aspects, the third plate surface 1131 may be an arc surface, and a central axis of the arc surface is located on a side of the flexible circuit board 110 where the third plate surface 1131 is located; the third plate surface 1131 is designed to be an arc surface, so that the connection between the third plate surface 1131 and the first plate surface 1111 and the connection between the third plate surface 1131 and the second plate surface 1121 are both smooth, and the damage phenomenon of a circuit and the like on the flexible circuit board 110 can be avoided. In other exemplary embodiments, the third plate surface 1131 may be a plane, and the third plate surface 1131 and the first plate surface 1111, and the third plate surface 1131 and the second plate surface 1121 are disposed at an included angle; thus, compared with the case of directly connecting the first plate surface 1111 and the second plate surface 1121, a smaller included angle between the first plate surface 1111 and the second plate surface 1121 can be replaced by a larger included angle between the third plate surface 1131 and the first plate surface 1111 and between the third plate surface 1131 and the second plate surface 1121, so as to prevent the circuit on the flexible circuit board 110 from being damaged due to over bending. In still other exemplary aspects, referring to fig. 4, the third plate surface 1131 may be planar, and the third plate surface 1131 is coplanar with the first plate surface 1111 or the third plate surface 1131 is coplanar with the second plate surface 1121; thus, the third plate surface 1131 and the first plate surface 1111 can be regarded as an integral body or the third plate surface 1131 and the second plate surface 1121 can be regarded as an integral body, so that the size of the area of the third portion 113 does not need to be considered during manufacturing, and the difficulty in molding is reduced. It is understood that the arrangement of the third plate surface 1131 may be other forms, and the arrangement of the third plate surface 1131 is diversified and can be flexibly selected according to specific use requirements.
Specifically, when the second portion 112 is directly connected to the first portion 111, referring to fig. 5 and 6, the seventh surface 1411 may further include a second region 1413 connected between the first region 1412 and the first panel 1111, the second region 1413 may be coplanar with the first region 1412, and the sixth surface 133 may abut the first region 1412 and the second region 1413 and abut both the first region 1412 and the second region 1413. The inclined area of the seventh surface 1411 is directly extended to be connected to the first plate surface 1111, so that after the second reinforcing plate 130 is folded relative to the first reinforcing plate 120 to the sixth surface 133 and is attached to the first area 1412 and the second area 1413 of the seventh surface 1411, the connection among the first reinforcing plate 120, the second reinforcing plate 130 and the flexible circuit board 110 is tight, and operations such as gap filling are not required, thereby simplifying the molding process.
A first included angle between the first plate surface 1111 and the second plate surface 1121 may be an acute angle or an obtuse angle, and when the first included angle is an acute angle, the second portion 112 and the first portion 111 may be preferably connected at an interval, so as to avoid the second portion 112 and the first portion 111 from being bent to a greater extent, which may cause circuit damage; when the first included angle is an obtuse angle, the second portion 112 and the first portion 111 may be connected at an interval or directly.
It is to be understood that the limiting structure 140 may include any other structure capable of limiting the connection between the first reinforcing plate 120 and the second reinforcing plate 130 besides the first protrusion 141.

By respectively attaching the two wall surfaces of the second bump 142 where the notch 1422 is formed to the two wall surfaces of the third bump 143, the contact area between the third bump 143 and the second bump 142 can be increased, and the positioning accuracy of the first reinforcing plate 120 and the second reinforcing plate 130 can be improved.
Referring to fig. 8 and 9, by adjusting the inclination angle between the second wall 1432 and the sixth surface 133, the first reinforcing plate 120 and the second reinforcing plate 130 are limited by the third protrusion 143 and the notch 1422 on the second protrusion 142, and the obtained first portion 111 and the second portion 112 form different included angles.
