Description

Technical Field

[0001] The present invention relates to the technical field of fingerprint module installation structures for electronic devices, and particularly to a bracket assembly, a fingerprint module, and an electronic device for laterally installing a fingerprint module in an electronic device. Background Art

[0002] Currently, fingerprint unlocking devices are installed on electronic devices such as mobile phones and tablets. Generally, a fingerprint recognition button is installed on the battery cover or one side of the touch screen of the electronic device. Of course, there are also some devices that install the fingerprint recognition button on the side edge of the electronic device. For the current installation structure with the fingerprint module designed on the side, generally, the fingerprint recognition button is fixed through a slot opened on the side edge of the device. However, with the design of the overall size of the electronic device becoming thinner and thinner, the side edge of the current electronic device is not sufficient to stably fix the fingerprint recognition button, and during use, the fingerprint recognition button is likely to fall off from the slot, seriously affecting the user experience. Summary of the Invention

[0003] One object of the present invention is to provide a bracket assembly for laterally installing a fingerprint module in an electronic device to stably and effectively fix the fingerprint recognition button installed on the side edge of the electronic device and prevent it from falling off in order to solve the deficiencies of the above technical problems.

[0004] Another object of the present invention is to provide a fingerprint module that can be installed on the side edge of an electronic device to stably and effectively fix the fingerprint recognition button installed on the side edge of the electronic device and prevent it from falling off.

[0005] Another object of the present invention is to provide an electronic device with a fingerprint module installed on the side to stably and effectively fix the fingerprint recognition button installed on the side and prevent it from falling off.

[0006] To achieve the above objects, the present invention discloses a bracket assembly for laterally installing a fingerprint recognition button on an electronic device. The bracket assembly includes a support frame, a pressing strip, and a limiting plate;

[0023] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following is described in detail in conjunction with the embodiments and with reference to the drawings.

[0024] As Figures 1 to 5As shown in the figure, the present invention discloses an electronic device 1. Taking a mobile phone as an example, the electronic device 1 includes a housing 10 and a fingerprint module installed on the housing 10. The fingerprint module includes a fingerprint recognition button 20 and a function button 21 (such as a power button using a membrane switch). The function button 21 is installed behind the fingerprint recognition button 20, so that the mobile phone can be controlled by both the fingerprint recognition button 20 and the function button 21. An installation groove 11 for installing the fingerprint recognition button 20 is provided on the side of the housing 10. A through-open accommodation groove 12 communicating with the installation groove 11 is provided at a position opposite to the installation groove 11 inside the housing 10. A support assembly for installing the fingerprint module is provided in the accommodation groove 12.

[0025] Specifically, the support assembly includes a support frame 30, a pressing strip 31 and a limiting plate 32.

[0026] A support platform 300 is provided on the support frame 30. A connecting portion 301 is provided on each side of the support platform 300. A fixing portion is also provided on each side of the support platform 300. The support platform 300 is used for installing and fixing the function button 21, and the fixing portion is used for detachably fixing the support frame 30 on the housing 10 of the electronic device 1.

[0027] The pressing strip 31 includes a pressing portion 310 and two connecting and mating portions 311 located on both sides of the pressing portion 310. The pressing portion 310 can undergo elastic deformation under a pressing force to approach or move away from the function button 21. Through the detachable connection structure of the connecting portion 301 and the connecting and mating portion 311, the pressing strip 31 can be detachably installed and fixed on the support frame 30.

[0028] The limiting plate 32 is arranged above the pressing strip 31. The limiting plate 32 is used for installing and fixing the fingerprint recognition button 20, and both ends of the limiting plate 32 extend beyond both ends of the fingerprint recognition button 20 to form a skirt 320 of the fingerprint recognition button 20.

[0029] Through the setting of the support assembly with the above structure, first, since the size of the installation groove 11 is equivalent to the size of the fingerprint recognition button 20, therefore, the skirt 320 formed by the limiting plate 32 abuts against the inner wall of the accommodation groove 12 for accommodating the support frame 30 to limit the fingerprint recognition button 20 from detaching from the installation groove 11. In this embodiment, as Figure 2, the Y-axis limit of the fingerprint recognition button 20 is realized through the installation groove 11, and the X-axis limit of the fingerprint recognition button 20 is realized through the skirt 320 formed by the limiting plate 32, thereby forming a stable installation of the fingerprint recognition button 20. Secondly, the support frame 30 and the pressing bar 31 are detachably connected, which is convenient for rework during installation, and the middle frame of the electronic device 1 will not be damaged during rework. In addition, the above-mentioned bracket assembly supports an inside-out installation method, which can effectively reduce the demand for installation space, so that the overall width of the electronic device 1 can be designed to be smaller. In this embodiment, the installation method of the fingerprint module is:

[0030] 1) Install the function key 21 with the flexible PCB board on the support platform 300 on the support frame 30;

[0031] 2) Connect the two connecting parts 311 on both sides of the pressing strip 31 with the two connecting parts 301 on the support frame 30 to complete the installation of the pressing strip 31;

[0032] 3) Install the fingerprint recognition button 20 with the limiting plate 32 in the installation groove 11 on the housing 10 from the opening side of the accommodating groove 12;

[0033] 4) Install the support frame 30 installed in the above step 2) in the receiving groove 12, and then fix the support frame 30 by the fixing part to complete the entire installation work.

[0034] Furthermore, the connection part 301 is a connection column protruding from the support frame 30, and the connection matching part 311 is a connection hole provided on the pressing strip 31 and adapted to the connection column. Through the cooperation of the connection column and the connection hole, the pressing strip 31 and the support frame 30 are pluggable and connected, which is convenient for disassembly and assembly.

[0035] Preferably, if Figure 5 A downwardly protruding pressure head 312 is also provided on the bottom wall of the pressing portion 310 of the pressing strip 31. The pressure head 312 is used to abut against the function key 21, thereby effectively improving the sensitivity of the pressing portion 310. In addition, an upwardly protruding support platform 313 is also provided on the top wall of the pressing portion 310 of the pressing strip 31. The top surface of the support platform 313 is higher than the top surface of the connecting column. In this embodiment, by providing the support platform 313, a clearance space can be left between the skirt 320 and the connecting column to prevent the skirt 320 and the connecting column from interfering with each other in installation.

[0036] For further information, please refer to Figure 2 and Figure 5, the fixing part includes a U-shaped elastic piece 302 arranged outside one of the connecting parts 301. A lock head 303 is further arranged on the outer wall of the U-shaped elastic piece 302. A lock groove 120 adapted to the lock head 303 is arranged on the side wall of the accommodating groove 12 close to the lock head 303. The lock head 303 can enter and exit the lock groove 120 through the elastic change of the U-shaped elastic piece 302. Through the cooperation of the lock head 303 and the lock groove 120, the fixing of one side of the support frame 30 is realized.

[0037] Preferably, please refer to Figure 3 and Figure 5 , the fixing part further includes a baffle 304 extending upwardly arranged outside the other connecting part 301. The baffle 304 can abut against the inner side wall of the upper edge of the notch of the accommodating groove 12. During installation, the support frame 30 can be first obliquely inserted into the accommodating groove 12 so that the baffle 304 is placed behind the upper edge of the accommodating groove 12. Through the baffle 304, the fixing of the other side of the support frame 30 is realized.

[0038] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
