[0003] However, when the FPC board is assembled into the housing of a mobile device and is bent and attached to the bending area inside the housing, due to the non-tight fit between the FPC board and the bending area of the housing, there are minute gaps, and the minute gaps in the bending area are filled with gas to form bubbles, which cause the FPC board to bulge, thus affecting the antenna performance and service life of the mobile device. Summary of the Utility Model

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art, and to provide an FPC component for exhausting gas and a mobile device, which can prevent the FPC board from bulging by exhausting the gas in the bending area of the housing through the first exhaust through-hole on the FPC board, thereby improving the antenna performance and service life.

The FPC board includes a first FPC sub-board and a second FPC sub-board connected to each other. The first FPC sub-board is disposed on the first surface of the bending area, and the second FPC sub-board is disposed on the second surface of the bending area. Wherein, the first FPC sub-board is provided with a first exhaust groove, the second FPC sub-board is provided with a second exhaust groove, the first exhaust groove and the second exhaust groove are communicated to form a first exhaust through-hole, and the first exhaust through-hole is correspondingly disposed with the bending area.

[0027] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0028] As Figures 1 to 3As shown, the FPC component 10 for exhausting gas in one embodiment includes a housing 200 and an FPC board 100. The FPC board 100 is disposed in the bending area 210 of the housing 200. The FPC board 100 includes a first FPC sub-board 110 and a second FPC sub-board 120 which are connected to each other. The first FPC sub-board 110 is disposed on the first surface of the bending area 210, and the second FPC sub-board 120 is disposed on the second surface of the bending area 210. Among them, a first exhaust groove 110a is formed in the first FPC sub-board 110, and a second exhaust groove 120a is formed in the second FPC sub-board 120. The first exhaust groove 110a and the second exhaust groove 120a communicate with each other to form a first exhaust through hole 100a, and the first exhaust through hole 100a is correspondingly disposed with the bending area 210.

[0029] It can be understood that by respectively forming the first exhaust groove 110a and the second exhaust groove 120a which communicate with each other on the first FPC sub-board 110 and the second FPC sub-board 120 to form the first exhaust through hole 100a, and the first exhaust through hole 100a is correspondingly disposed with the bending area 210, when the first FPC sub-board 110 and the second FPC sub-board 120 are attached, the gas generated in the bending area 210 of the housing 200 can be discharged in time through the first exhaust through hole 100a, reducing the gas accumulation in the bending area 210 of the housing 200 and avoiding the problem that the gas is trapped inside the FPC board 100 resulting in the bulging of the FPC board 100, thereby improving the antenna performance and service life of the mobile device.

[0030] It can also be understood that in the prior art, the FPC board 100 is attached to the bending area 210 inside the housing 200. Since the FPC board 100 does not have an exhaust through hole, the operator needs to gradually discharge the gas by slowly attaching the FPC board 100. However, for the FPC component 10 for exhausting gas in the present disclosure, by correspondingly disposing the first exhaust through hole 100a with the bending area 210, on the one hand, the installation process is simplified and the installation efficiency of the FPC board 100 is improved. On the other hand, the gas in the bending area 210 inside the housing 200 can be directly discharged through the first exhaust through hole 100a, improving the overall gas discharge effect and efficiency.

[0031] Further, in one embodiment, the first exhaust through hole 100a is in a circular hole shape. It can be understood that when the gas is discharged through the circular hole-shaped first exhaust hole, since the periphery of the circular hole shape is relatively smooth, the resistance is relatively small, and the gas in the bending area 210 can be discharged more smoothly, thereby improving the exhaust effect and efficiency of the first exhaust through hole 100a of the FPC board 100.

[0032] Further, in one embodiment, the diameter of the first exhaust through-hole 100a is 0.8 mm - 1 mm. It can be understood that since the diameter of the first exhaust through-hole 100a is 0.8 mm - 1 mm, the size of the first exhaust through-hole 100a is appropriate, which can not only ensure the exhaust efficiency of the first exhaust through-hole 100a, but also ensure the structural strength of the FPC board 100, avoiding breakage or damage of the FPC board 100 during bending, thereby improving the service life and exhaust efficiency of the FPC board 100.

[0033] Further, in one embodiment, the number of the first exhaust through-holes 100a is multiple, and the multiple first exhaust through-holes 100a are arranged at intervals along the length direction of the first FPC sub-board 110. It can be understood that since the multiple first exhaust through-holes 100a are arranged at intervals along the length direction of the first FPC sub-board 110, the multiple first exhaust through-holes 100a can provide more exhaust channels for the bending area 210 of the housing 200, enabling the gas in the bending area 210 to be discharged more quickly and fully, further reducing the problem of the FPC board 100 bulging due to gas accumulation in the bending area 210, thereby improving the antenna performance and service life of the mobile device.

[0034] Preferably, in one embodiment, the distance between every two first exhaust through-holes 100a is 3 mm - 4 mm. It can be understood that since the distance between every two first exhaust through-holes 100a is 3 mm - 4 mm, the gas in the bending area 210 can be evenly discharged from each first exhaust through-hole 100a, avoiding local gas accumulation or unsmooth discharge in the bending area 210, thereby improving the exhaust efficiency and effect; if the distance between every two first exhaust through-holes 100a is less than 3 mm, it is easy to cause the weakening of the structural strength of the FPC board 100 and affect the overall structural performance. If the distance between every two first exhaust through-holes 100a is greater than 4 mm, it is easy to affect the overall exhaust effect and efficiency. Therefore, the design of the distance between every two first exhaust through-holes 100a being 3 mm - 4 mm can not only ensure a certain structural strength of the FPC board 100, but also improve the effective discharge of the gas in the bending area 210 of the housing 200 by the first exhaust through-hole 100a, improve the service life of the FPC board 100, and thereby improve the antenna performance and service life of the mobile device.

[0035] Such as Figure 1 and Figure 2As shown, in one embodiment, the FPC board 100 further includes a third FPC sub-board 130. The third FPC sub-board 130 extends into the housing 200 along the second FPC sub-board 120. The third FPC sub-board 130 is provided with a second exhaust through-hole 130a. It can be understood that the second exhaust through-hole 130a is used to discharge the gas at other positions of the FPC board 100 attached to the housing 200 except for the bending area 210, so as to avoid the problem that the gas at other attachment positions cannot be discharged, resulting in the bulging of the FPC board 100. Therefore, the third FPC sub-board 130 being provided with the second exhaust through-hole 130a effectively improves the exhaust effect and service life of the FPC board 100.

[0036] In one embodiment, the number of the second exhaust through-holes 130a is multiple, and each second exhaust through-hole 130a is in a round hole shape. It can be understood that when the gas is discharged through the round-hole-shaped second exhaust hole, since the periphery of the round hole shape is relatively smooth, the resistance is relatively small, and the gas at other attachment positions in the housing 200 can be discharged more smoothly, improving the exhaust effect and efficiency of the second exhaust through-hole 130a of the FPC board 100; the multiple second exhaust through-holes 130a provided can provide multiple exhaust channels for other attachment positions in the housing 200, enabling the gas at other attachment positions in the housing 200 to be quickly discharged, avoiding the problem of the FPC board 100 bulging, and thus improving the antenna performance and service life of the mobile device.

[0037] In one embodiment, the diameter of the second exhaust through-hole 130a is 0.8 mm - 1 mm. It can be understood that when the diameter of the second exhaust through-hole 130a is 0.8 mm - 1 mm, it helps to achieve a more appropriate exhaust effect. If the diameter of the second exhaust through-hole 130a is less than 0.8 mm, it is easy to cause unsmooth exhaust when the FPC board 100 is attached to the housing 200, resulting in the bulging of the FPC board 100 and affecting the service life of the FPC board 100; if the diameter of the second exhaust through-hole 130a is greater than 1 mm, it is easy to cause the FPC board 100 to have poor structural strength, thus affecting the service life of the FPC board 100.

[0038] As Figure 1 and Figure 2As shown, in one embodiment, the FPC component 10 for exhausting gas further includes an installation positioning post 300, and the installation positioning post 300 is arranged inside the housing 200; the second FPC sub-board 120 is provided with a positioning installation groove 121, and the positioning installation groove 121 is arranged corresponding to the installation positioning post 300. It can be understood that since the positioning installation groove 121 is arranged corresponding to the installation positioning post 300, the positioning installation groove 121 on the second FPC sub-board 120 can be accurately installed on the installation positioning post 300 inside the housing 200, reducing the error in installing the FPC board 100, thereby improving the assembly accuracy of the FPC board 100. At the same time, when the FPC board 100 needs to be replaced or maintained, it can be disassembled and installed quickly and accurately, improving the efficiency of disassembling and installing the FPC board 100.

[0039] The present disclosure also provides a mobile device, including the FPC component 10 for exhausting gas according to any one of the above embodiments.

[0040] Compared with the prior art, the present disclosure has at least the following advantages:

[0041] 1) By respectively providing a first exhaust groove 110a and a second exhaust groove 120a that are connected and communicated on the first FPC sub-board 110 and the second FPC sub-board 120 to form a first exhaust through-hole 100a, and the first exhaust through-hole 100a is arranged corresponding to the bending area 210, when the first FPC sub-board 110 and the second FPC sub-board 120 are being attached, the gas generated in the bending area 210 of the housing 200 can be discharged in time through the first exhaust through-hole 100a, reducing the accumulation of gas in the bending area 210 of the housing 200 and avoiding the problem that the gas is trapped inside the FPC board 100 and causes the FPC board 100 to bulge, thereby improving the antenna performance and service life of the mobile device.

[0042] 2) In the prior art, the FPC board 100 is attached to the bending area 210 inside the housing 200. Since the FPC board 100 is not provided with an exhaust through-hole, the operator needs to gradually discharge the gas by slowly attaching the FPC board 100. However, for the above-mentioned FPC component 10 for exhausting gas, by arranging the first exhaust through-hole 100a corresponding to the bending area 210, on the one hand, the installation process is simplified, and the installation efficiency of the FPC board 100 is improved. On the other hand, the gas in the bending area 210 inside the housing 200 can be directly discharged through the first exhaust through-hole 100a, improving the overall effect and efficiency of discharging the gas.

[0043] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
