[0027] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this utility model.

[0028] In order to solve the problems of redundant dimensions, single overall product shape, complex structure, numerous parts and complex manufacturing process in current fingerprint modules, the applicant has developed a new type of fingerprint module with an ultra-thin design, compact structure, easy production and assembly, and convenient for users to operate quickly.

[0029] Specifically, see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an embodiment of the fingerprint module of the present application. Figure 2 This is a structural diagram of the fingerprint module of this application from another perspective.

[0030] like Figure 1 and Figure 2 As shown, the fingerprint module includes a housing 10, and an accommodating space 20 ( Figure 1 and 2 (not shown), a fingerprint recognition unit 30 is limited in the accommodating space 20, and a signal line 301 of the fingerprint recognition unit 30 is extended from the inside of the shell.

[0031] In the first direction x, the diameter of the housing 10 is gradually reduced, and synchronously, the inner diameter of the accommodating space 20 is gradually reduced along the first direction x.

[0032] Based on the above design, under the premise of meeting the assembly requirements of the fingerprint recognition unit 30, the edge thickness of the housing 10 is relatively small, and the whole housing 10 presents an ultra-thin effect and a compact structure.

[0033] In this embodiment, the shell 10 includes an upper shell 101 and a lower shell 102 that cooperate with each other, and the upper shell 101 and the lower shell 102 are arranged in sequence along the first direction x; in other embodiments, the shell can also be assembled from sub-shells of other numbers or other arrangements, for example, the shell can also be assembled from multiple sub-shells arranged in sequence in the second direction y, or it can also be assembled from an upper shell 101, a middle shell, and a lower shell 102 arranged in sequence in the first direction x, all of which can achieve the effects of this embodiment.

[0034] like Figure 2 As shown, in this embodiment, the lower shell 102 includes a base plate 1021 and an annular plate 1022 arranged on the outer edge of one side of the base plate 1021. The annular plate 1022 encloses a accommodating space 20 for installing the fingerprint recognition unit 30. The upper shell 101 is covered on the annular plate 1022 to seal the accommodating space 20.

[0035] The annular plate 1022 includes side plates 10221 located around the bottom plate 1021. The side plates 10221 are all inclined, so that the inner diameter of the accommodating space 20 decreases sequentially along the first direction, and the fingerprint module is ultra-thin all around.

[0036] Of course, in other embodiments, one or more side panels 10221 of the lower housing 102 may be tilted, thereby creating an ultra-thin effect on part of the edge of the fingerprint module.

[0037] In order to achieve transition at the corners of the lower shell 102 and realize an overall streamlined design, in this embodiment, the annular plate 1022 further includes an arc-shaped transition plate 10222 located between adjacent side plates 10221 .

[0038] Furthermore, the side panels 10221 are curved panels that curve outward along the first direction x. In other embodiments, only the side panels 10221 on opposite sides of the bottom panel 1021 may be curved panels, or adjacent side panels 10221 may be connected to each other, thereby still achieving the ultra-thin design of this embodiment.

[0039] It should be noted that, in this embodiment, the base plate 1021 is a rectangular structure, and the side plates 10221 are arranged on both sides and both ends of the base plate 1021, so that the base plate 1021 has an ultra-thin effect on all sides. In other embodiments, based on actual needs, the base plate 1021 can also be other shapes, such as circular, elliptical, polygonal, etc. The shape of the annular plate 1022 can be adaptively adjusted to achieve the tilted setting of each side of the fingerprint module, and the fingerprint module can have an ultra-thin effect on all sides. For example, when the base plate 1021 is circular, the annular plate 1022 can be a conical cylinder structure with the cone angle pointing to the base plate 1021.

[0040] Next, we will continue to introduce the internal structure of the housing 10. Figure 3 , Figure 3 This is a schematic diagram of the exploded structure of an embodiment of the fingerprint module of the present application.

[0041] like Figure 3 As shown, in this embodiment, the fingerprint recognition unit 30 includes a fingerprint recognition button 302, a mainboard 303, and a signal line 301, which are arranged in this order. To secure the signal line 301, a limiting hole 3011 is provided on the signal line 301, and a positioning post 1023 is arranged on the inner surface of the lower housing 102, corresponding to the position of the limiting hole 3011. The positioning post 1023 passes through the limiting hole 3011 and is fixed to the signal line 301.

[0042] Specifically, in this embodiment, a screw hole 10231 is arranged inside the positioning column 1023 , and the positioning column 1023 is fixed to the signal line 301 by a bolt inserted into the screw hole 10231 .

[0043] In other embodiments, the positioning posts 1023 may also be arranged on the inner surface of the upper shell 101 , or simultaneously arranged on the inner surfaces of the upper shell 101 and the lower shell 102 , both of which can achieve the effect of this embodiment.

[0044] Furthermore, in this embodiment, the positioning posts 1023 on the inner surface of the lower housing 102 can also be fixed to the upper housing 101 , thereby fixing the upper housing 101 and the lower housing 102 while fixing the signal line 301 .

[0045] See also Figure 4 , Figure 4 yes Figure 3 A is a partial enlarged schematic diagram in FIG. Figure 4 As shown, in this embodiment, the signal line 301 includes a limiting section 3012, and the cable 3013 of the limiting section 3012 is exposed. The cable 3013 at the center of the limiting section 3012 is bent outward to form a limiting hole 3011. In other embodiments, the limiting hole 3011 of the signal line 301 can also be arranged in other ways, for example, the cable 3013 on the side of the signal line 301 can be bent inward, etc., and the effects of this embodiment can still be achieved.

[0046] Please continue reading Figure 3 In order to fix the fingerprint recognition unit 30 inside the accommodating space 20, in this embodiment, the inner surface of the lower shell 102 is further arranged with two limiting protrusions 1024 arranged at intervals along the second direction y. The two limiting protrusions 1024 can cooperate to limit the signal line 301 in the gap therebetween, thereby further improving the fixing stability of the fingerprint recognition unit 30.

[0047] In other embodiments, the limiting protrusions may also be arranged on the inner surface of the upper shell 101, or may also be arranged on the inner surfaces of the upper shell 101 and the lower shell 102 at the same time. In addition, based on actual working conditions, multiple groups of limiting protrusions 1024 may also be arranged on the inner surfaces of the upper shell 101 and / or the lower shell 102. Each group of limiting protrusions 1024 may include multiple limiting protrusions 1024 arranged at intervals, so as to adapt to different models of fingerprint recognition units 30.

[0048] The fingerprint module based on the above-mentioned embodiments realizes miniaturization and ultra-thin design while ensuring the fixed stability of the fingerprint recognition unit 30. It has a simple structure, is easy to produce and assemble, and is easy for users to use and carry. The production, packaging and transportation costs are low.
