Description

Technical Field

[0001] This utility model belongs to the field of fingerprint recognition technology, and in particular relates to a structure with a fingerprint module that allows for pressing. Background Technology

[0002] The fingerprint module is the core component of a fingerprint lock. It is installed on devices such as fingerprint access control systems or hard drives and is used to complete fingerprint acquisition and recognition. The fingerprint module mainly consists of a fingerprint acquisition module, a fingerprint recognition module, and an extended function module.

[0003] Most fingerprint modules are powered on even when not in use, which can easily lead to accidental activation due to accidental touches, causing signal corruption. In addition, prolonged power-on not only increases power consumption but also reduces the lifespan of the fingerprint module. To address this, a fingerprint module structure with a press function is provided. Utility Model Content

[0004] The purpose of this invention is to solve the problem that current fingerprint modules are prone to false activation, leading to signal corruption, and to propose a fingerprint module structure with a press function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a structure with a fingerprint module, including a lower cover and an upper cover, a bracket is fixedly installed on the inner wall of the lower cover, the bracket is configured as a notch, a fingerprint module is slidably installed on the inner wall of the notch of the bracket, a main control PCB board is fixedly installed on the inner wall of the lower cover, and a switch is electrically connected to the upper surface of the main control PCB board.

[0006] As a further description of the above technical solution:

[0007] The bottom surface of the bracket has a through hole, and a compression spring is fixedly installed on the inner wall of the bottom surface of the bracket. The size of the compression spring is adapted to the recess of the bracket.

[0008] As a further description of the above technical solution:

[0009] The lower cover and the upper cover are fixedly connected. The upper surface of the upper cover is provided with a groove. The lower surface of the fingerprint module is fixedly connected to one end of the compression spring. The fingerprint module and the groove of the upper cover are mutually adapted.

[0010] As a further description of the above technical solution:

[0011] A sealing ring is fixedly installed on the outer surface of the fingerprint module, and the sealing ring is in contact with the inner wall of the upper cover groove.

[0012] As a further description of the above technical solution:

[0013] One end of the switch extends into the interior of the bracket through a through hole, and the other end of the switch is located inside the compression spring and contacts the lower surface of the fingerprint module.

[0014] As a further description of the above technical solution:

[0015] The lower surface of the main control PCB board is electrically connected to a data line, and the lower surface of the lower cover is provided with a hole, on the inner wall of which a wire plug is fixedly installed.

[0016] As a further description of the above technical solution:

[0017] One end of the data cable extends through a plug to the outside of the lower surface of the cover.

[0018] As a further description of the above technical solution:

[0019] Both the main control PCB board and the inner wall of the fingerprint module are electrically connected to sockets, and the two sockets are connected by the fingerprint module data cable.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, a spring and a switch are incorporated. When the fingerprint module needs to be activated, the switch is activated by gently pressing down on the fingerprint module. As the fingerprint module moves downward, the spring is compressed. After the main control PCB detects the switch's state, the socket on the main control PCB supplies power to the socket on the fingerprint module via the fingerprint module's data cable, thus putting the fingerprint module into working mode. This prevents the fingerprint module from being accidentally activated when not in use, reducing the likelihood of accidental touches. It also prevents increased power consumption due to prolonged power supply, achieving energy savings. Furthermore, it avoids reduced product lifespan due to frequent detection while maintaining power, ensuring both the lifespan and stability of the fingerprint module after extended operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4 This utility model provides a technical solution: a structure with a fingerprint module, including a lower cover 1 and an upper cover 2. A bracket 6 is fixedly installed on the inner wall of the lower cover 1. The bracket 6 is shaped like a notch. A fingerprint module 3 is slidably installed on the inner wall of the notch of the bracket 6. A main control PCB board 4 is fixedly installed on the inner wall of the lower cover 1. A switch 5 is electrically connected to the upper surface of the main control PCB board 4. A through hole is provided on the bottom surface of the bracket 6. A compression spring 7 is fixedly installed on the inner wall of the bottom surface of the bracket 6. The compression spring 7 is adapted to the size of the notch of the bracket 6. The lower cover 1 and the upper cover 2 are fixedly connected. A groove is provided on the upper surface of the upper cover 2. The lower surface of the fingerprint module 3 is fixedly connected to one end of the compression spring 7. The fingerprint module 3 and the slot of the upper cover 2 are mutually adapted. A sealing ring 8 is fixedly installed on the outer surface of the fingerprint module 3. The sealing ring 8 fits against the inner wall of the slot of the upper cover 2. One end of the switch 5 extends into the interior of the bracket 6 through a through hole. One end of the switch 5 is located inside the compression spring 7 and contacts the lower surface of the fingerprint module 3. A data cable 10 is electrically connected to the lower surface of the main control PCB board 4. A hole is provided on the lower surface of the lower cover 1. A wire plug 9 is fixedly installed on the inner wall of the hole. One end of the data cable 10 extends to the outside of the lower surface of the lower cover 1 through the wire plug 9. Sockets 11 are electrically connected to the inner walls of the main control PCB board 4 and the fingerprint module 3. The two sockets 11 are connected by the fingerprint module data cable.

[0030] The specific implementation method is as follows: When it is necessary to start the fingerprint module 3, the fingerprint module 3 is pressed down and the switch 5 is activated. At this time, the pressure spring 7 is in a compressed state when the fingerprint module 3 moves down. After the main control PCB board 4 detects the state of the switch 5, the socket 11 on the main control PCB board 4 supplies power to the socket 11 on the fingerprint module 3 through the fingerprint module data line, so that the fingerprint module 3 enters the working state. When the fingerprint module 3 finishes working, the pressure spring 7 will push the fingerprint module 3 upward. At this time, the switch 5 stops activating, so that the main control PCB board 4 stops supplying power to the fingerprint module 3, and the fingerprint module 3, which loses power, enters the off state.

[0031] Working principle: When the fingerprint module 3 needs to be activated, the fingerprint module 3 is pressed down and the switch 5 is activated. At this time, the pressure spring 7 is compressed when the fingerprint module 3 moves down. After the main control PCB board 4 detects the state of the switch 5, the socket 11 on the main control PCB board 4 supplies power to the socket 11 on the fingerprint module 3 through the fingerprint module data cable, so that the fingerprint module 3 enters the working state. When the fingerprint module 3 finishes working, the pressure spring 7 will push the fingerprint module 3 upward. At this time, the switch 5 stops activating, so that the main control PCB board 4 stops supplying power to the fingerprint module 3, and the fingerprint module 3 is turned off due to the loss of power.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
