[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0025] As described in the background technology, although the existing solution can realize pressure sensing and fingerprint recognition of the user, the fingerprint recognition module and the pressure sensing module are set separately, which not only increases the difficulty of subsequent assembly and reduces assembly efficiency, but also increases the thickness of the electronic device, making it difficult to apply to thinner electronic devices.

[0026] In order to solve this technical problem, the utility model provides a fingerprint recognition and pressure sensing integrated sensor and electronic equipment, which are applied in the sensor field.

[0027] Specifically, please refer to Figure 1-3 The fingerprint recognition and pressure sensing integrated sensor specifically includes a fingerprint recognition sensor 1 and a pressure sensing sensor 2, wherein the fingerprint recognition sensor 1 and the pressure sensing sensor 2 are bonded and fixed together by an adhesive layer 3; a flexible circuit board 4, wherein the flexible circuit board 4 is electrically connected to the fingerprint recognition sensor 1 and the pressure sensing sensor 2 respectively.

[0028] The fingerprint recognition and pressure sensing integrated sensor and electronic device provided by the utility model bond the pressure sensing sensor 2 and the fingerprint recognition sensor 1 together through OCA to form an integral structure, which reduces the difficulty of assembly in the later stage and greatly improves the assembly efficiency, achieves the dual effects of fingerprint recognition and pressure sensing for the electronic device, reduces the reserved installation space of the electronic device, and further reduces the thickness of the electronic device, and is suitable for thinner electronic devices.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] Example 1

[0033] Please refer to Figure 1-3 , a fingerprint recognition and pressure sensing integrated sensor is provided, which includes a fingerprint recognition sensor 1 and a pressure sensing sensor 2, the fingerprint recognition sensor 1 and the pressure sensing sensor 2 are bonded and fixed together by an adhesive layer 3, the fingerprint recognition sensor 1 and the pressure sensing sensor 2 are both electrically connected to a flexible circuit board 4, and the flexible circuit board 4 is connected to a control mainboard of an electronic device for pressure sensing and fingerprint recognition.

[0034] The adhesive layer 3 is OCA, and of course it can also be double-sided adhesive. In order to make the integrated sensor as thin as possible, the thickness of OCA needs to be as thin as possible, while also ensuring a certain degree of bonding firmness. In this embodiment, the thickness of OCA is 0.3-0.5mm, and the thickness does not exceed 2mm after the overall preparation is completed.

[0035] Moreover, both the fingerprint recognition sensor 1 and the pressure sensing sensor 2 are flexible structures. During manufacture, both sensors use flexible materials as substrates, and then a fingerprint recognition module or a pressure sensing electrode is arranged on the substrate, and an electrode circuit is laid on the substrate. After the fingerprint recognition sensor 1 and the pressure sensing sensor 2 are bonded together, they can be bent freely, have high flexibility, are easy to assemble, are not easily damaged, and have a long service life. Moreover, the fingerprint recognition sensor 1 is arranged on the upper side of the pressure sensing sensor 2. After the integrated sensor is assembled into an electronic device, the fingerprint recognition sensor 1 can be used to perform fingerprint recognition, and when the user presses down, pressure sensing can be performed through the pressure sensing sensor 2, thereby activating the operation.

[0036] This fingerprint recognition and pressure sensing integrated sensor is applied to electronic devices that require fingerprint recognition and pressure sensing. Fingerprint recognition is used to activate or decrypt electronic devices, such as a mouse 10, a car key, a car start button, and some other electronic devices.

[0037] like Figure 4As shown, in this example, a mouse 10 is taken as an example. The mouse 10 includes a main structure 11, a left button 12 and a right button 13. The main structure 11 is the structure of the existing mouse 10, which includes a shell and internal components, which are not described separately here. The integrated sensor is arranged on the left button 12 or the right button 13, and can also be arranged on the left button 12 and the right button 13 respectively. Since the fingerprint recognition sensor 1 and the pressure sensing sensor 2 are both flexible structures, the integrated sensor can be fixed on the left and right buttons 13 of the mouse 10 by double-sided adhesive, which is convenient for installation and use. The flexible circuit board 4 is electrically connected to the control main board in the mouse 10. The fingerprint recognition sensor 1 is used to unlock the computer, and when operating the computer, fingerprint recognition can be directly performed without entering a password, thereby reducing keyboard operations and improving user comfort. The pressure sensing sensor 2 is used to replace the physical buttons of the left button 12 and / or the right button 13 of the physical mouse 10, thereby reducing damage and increasing the service life of the mouse 10.

[0038] Example 2

[0039] The fingerprint recognition and pressure sensing integrated sensor provided in Example 1 is further optimized, specifically, as follows: Figure 1 As shown, the flexible circuit board 4 includes a fingerprint recognition FPC5 and a pressure sensing FPC6. The fingerprint recognition FPC5 is bound to the fingerprint recognition sensor 1, and the pressure sensing FPC6 is bound to the pressure sensing sensor 2. Two different flexible circuit boards 4 are respectively connected to the fingerprint recognition sensor 1 and the pressure sensing sensor 2, so that a separate control effect can be achieved. During use, if one of the flexible circuit boards 4 is damaged, it will not affect the electrical transmission of the other flexible circuit board 4.

[0040] Example 3

[0041] The fingerprint recognition and pressure sensing integrated sensor provided in Example 2 is further optimized, specifically, as follows: Figure 2 , 3 As shown, the flexible circuit board 4 is an integrated structure, which includes a first binding part 7 and a second binding part 8. The first binding part 7 is bound to the fingerprint recognition sensor 1, and the second binding part 8 is bound to the pressure sensing sensor 2. A first notch 9 is provided on the fingerprint recognition sensor 1, and the second binding part 8 is located at the first notch 9. The first binding part 7 and the second binding part 8 are staggered. A single flexible circuit board 4 is respectively connected to the fingerprint recognition sensor 1 and the pressure sensing sensor 2 to assemble into a GFF structure similar to a capacitive screen, thereby reducing the material used for the flexible circuit board 4 and saving material costs.

[0042] The working principle of the fingerprint recognition and pressure sensing integrated sensor and electronic device provided by the utility model is as follows: the pressure sensing sensor 2 and the fingerprint recognition sensor 1 are bonded together through OCA to form an integral structure, which reduces the difficulty of assembly in the later stage and greatly improves the assembly efficiency, thereby achieving the dual effects of fingerprint recognition and pressure sensing for the electronic device, reducing the reserved installation space of the electronic device, and further reducing the thickness of the electronic device, and is suitable for thinner electronic devices.
