[0029] Please see Figures 1 to 6 The present invention provides a side capacitive fingerprint component for a mobile phone and a mobile phone.

[0030] According to a first aspect of the present invention, a side-mounted capacitive fingerprint sensor for a mobile phone includes a metal ring 100 and a sensing component 200. The metal ring 100 is vertically continuous. A first opening 101 is provided at the upper end of the metal ring 100, and a second opening 102 is provided at the lower end of the metal ring 100. The first opening 101 and the second opening 102 are connected. The sensing component 200 includes a cover plate 210, a fingerprint recognition chip 220, an adhesive film 230, and a circuit board 240. The cover plate 210 is disposed at the first opening 101. The fingerprint recognition chip 220 is disposed inside the metal ring 100. The adhesive film 230 is disposed between the cover plate 210 and the fingerprint recognition chip 220 to connect the cover plate 210 and the fingerprint recognition chip 220. The circuit board 240 is located below the second opening 102 and is connected to the fingerprint recognition chip 220.

[0031] In this embodiment of the invention, the metal ring 100 is arranged vertically through the metal ring, enabling it to protect the fingerprint recognition chip 220 located inside the metal ring 100. The fingerprint recognition chip 220 is mounted on the circuit board 240, and the cover plate 210 is located at the first opening 101. The fingerprint recognition chip 220 is connected to the cover plate 210 via an adhesive film 230. During use, the user's finger can press against the cover plate 210 to abut against it, and the fingerprint recognition chip 220 can recognize the fingerprint of the finger pressed against the cover plate 210. By setting the cover plate 210, the fingerprint recognition chip 220 can protect the fingerprint chip 220 located inside the metal ring 100. The fingerprint recognition chip 220 is located under the cover plate 210 to prevent damage to the fingerprint recognition chip 220 from external substances. Moreover, compared with the traditional capacitive fingerprint structure chip with a matte paint coating, the cover plate 210 of the side capacitive fingerprint component for mobile phones in this application is located at the first opening 101. The user's finger comes into contact with the cover plate 210 of the side capacitive fingerprint component for mobile phones. In order to meet the design requirements, different materials of the cover plate 210 can be selected as needed, and the surface processing of the cover plate 210 is less difficult, making it easier to meet the design requirements.

[0032] Specifically, since the cover plate 210 is located at the first opening 101, when the user presses it, the user's fingers can come into contact with the edge of the cover plate 210 and the metal ring 100 where the first opening 101 is located. By setting the metal ring 100, the degree of excessive pressure on the cover plate 210 by the user can be reduced, the possibility of damage to the cover plate 210 and the fingerprint recognition chip 220 can be reduced, and the security of use can be improved.

[0033] Specifically, the cover plate 210 can be a glass cover plate. Depending on the specific situation, the cover plate 210 can also be made of gemstone. The color of the cover plate 210 can be mixed using a color palette. The cover plate 210 is a glass cover plate, and the adhesive film 230 is a DAF film. The glass cover plate is bonded to the surface of the fingerprint recognition chip 220 with the DAF film, so that the surface of the side capacitive fingerprint component used in the mobile phone presents the glossy effect of the cover plate 210.

[0034] The metal ring 100 protects the glass cover from cracking or damage under external force. The side capacitive fingerprint component used in mobile phones features a glossy glass cover on the front and a polished metal ring 100 around the edges. This not only meets customers' aesthetic requirements for high-end mobile phones but also makes the buttons feel smoother, solving the problem that previous matte fingerprint modules could not meet customers' high-gloss requirements.

[0035] Furthermore, the cover plate 210 can be made of various materials according to customer needs, such as glass, sapphire, ruby, etc., with a base ink. The gloss effect of the cover plate 210 on the front is different depending on the material. Both the cover plate 210 and the metal ring 100 are glossy and can be assembled in the same or different colors according to customer needs, so as to meet the different appearance effects of the whole machine, thereby improving the appearance effect and user experience of the whole machine after installation.

[0036] Reference Figures 1 to 3 In some embodiments of this utility model, a steel sheet reinforcing member 300 is also included. The steel sheet reinforcing member 300 is connected to the side of the circuit board 240 away from the fingerprint recognition chip 220 and is connected to the metal ring 100.

[0037] When the user presses the cover plate 210, the cover plate 210 and the fingerprint recognition chip 220 move downwards, causing the circuit board 240 connected to the chip to move downwards. By setting the steel sheet reinforcement 300, the structural strength of the circuit board 240 can be strengthened, reducing the degree of damage caused by bending of the circuit board 240 under stress.

[0038] The steel sheet reinforcement 300 is connected to the metal ring 100 to limit the position of the steel sheet reinforcement 300 and further improve the protection effect of the circuit board 240.

[0039] Reference Figure 1 and Figure 6 In some embodiments of this utility model, the steel sheet reinforcement 300 includes a first body 310 and an elastic connector 320; the first body 310 is connected to the circuit board 240 and the metal ring 100; the length direction of the first body 310 is arranged in the same direction as the length direction of the circuit board 240; the elastic connector 320 is disposed on the side of the first body 310 away from the circuit board 240.

[0040] The length direction of the first main body 310 is set in the same direction as the length of the circuit board 240, so that the length of the part of the first main body 310 connected to the circuit board 240 is longer, thereby improving the degree of protection of the circuit board 240 by the steel sheet reinforcement 300.

[0041] The elastic connector 320 is L-shaped and is connected to the first main body 310. When the user presses down on the cover plate 210, the cover plate 210 will move downward, causing the chip, circuit board 240 and steel sheet reinforcement 300 to move downward. The steel sheet reinforcement 300 is connected to the outside through the elastic connector 320. Because the elastic connector 320 is elastic, it can play a buffering role and reduce the degree of excessive pressure on the cover plate 210 and the chip.

[0042] Specifically, the steel sheet reinforcement 300 is integrally formed with the circuit board 240 to reduce processing difficulty and processing costs.

[0043] Reference Figure 6 In some embodiments of this utility model, the elastic connector 320 includes a first connecting plate 321 and a second connecting plate 322. The two ends of the first connecting plate 321 are respectively connected to one end of the second connecting plate 322 and the first body 310. The length direction of the second connecting plate 322 is arranged in the same direction as the length direction of the first body 310. Two elastic connectors 320 are provided and symmetrically arranged. The second connecting plates 322 of the two elastic connectors 320 extend in directions that are far apart from each other.

[0044] The external structure is connected to the second connecting plate 322. Because the elastic connecting plate is elastic, when the user presses down on the cover plate 210, the cover plate 210 will move downward, causing the chip, circuit board 240 and steel sheet reinforcement 300 to move downward, and the second connecting plate 322 will deform to achieve a buffering effect.

[0045] Specifically, the elastic connector 320 is L-shaped; the length direction of the first connecting plate 321 is perpendicular to the length direction of the second connecting plate 322; the two elastic connectors 320 are symmetrically arranged, and the second connecting plates 322 of the two elastic connectors 320 extend in a direction away from each other, reducing the difficulty of connecting the external structure with the two elastic connectors 320.

[0046] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments of this utility model, the metal ring 100 includes a side structure 110 and a second body 120; the second body 120 is arranged vertically, and the first opening 101 and the second opening 102 are respectively arranged at the upper end and the lower end of the second body 120; the side structure 110 is arranged on the side of the second body 120 and is connected to the steel sheet reinforcement 300.

[0047] Both the first opening 101 and the second opening 102 are formed on the second body 120, and the second body 120 is connected to the steel sheet reinforcement 300 through the side structure 110; wherein, the side structure 110 and the second body 120 are integrally formed, which makes the processing of the metal ring 100 easier and reduces costs.

[0048] Reference Figure 4 and Figure 5 In some embodiments of this utility model, two side structures 110 are provided, and are respectively provided on opposite sides of the second main body 120.

[0049] The second main body 120 is connected to the steel sheet reinforcement 300 through two side structures 110, which can improve the stability of the connection between the metal ring 100 and the steel sheet reinforcement 300.

[0050] Specifically, the two side structures 110 of the metal ring 100 can be fixed in the overall structure by means of locking.

[0051] Reference Figure 2 In some embodiments of this utility model, the upper surface of the cover plate 210 is flush with the upper surface of the metal ring 100, so as to reduce the difficulty for users to press the cover plate 210.

[0052] Of course, depending on the specific circumstances, the cover plate 210 can be retracted into the metal ring 100, so that there is a certain distance between the upper end face of the cover plate 210 and the upper end face of the metal ring 100.

[0053] Reference Figure 1 and Figure 3 In some embodiments of this utility model, an injection-molded support 400 is also included, which is disposed on the side of the steel sheet reinforcement 300 away from the metal ring 100.

[0054] The injection-molded support 400 can be set to support the comfortable feel of pressing the chip.

[0055] Reference Figure 1 and Figure 3 In some embodiments of this utility model, a connecting layer is also included; the connecting layer is disposed between the injection molded support 400 and the steel sheet reinforcement 300 to connect the injection molded support 400 and the steel sheet reinforcement 300.

[0056] The stability of the connection between the injection-molded support 400 and the steel sheet reinforcement 300 can be improved by setting a connecting layer; the connecting layer can be formed by curing adhesive.
