The above-mentioned drawbacks are the results of the inventor after practical and careful study, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to the above-mentioned problems should be the contribution of the inventor in the process of the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

Referring to fig. 1, fig. 1 shows a schematic structural diagram of a face recognition module 10 according to an embodiment of the present application. The face recognition module 10 is composed of a plurality of stacked layer structures. Illustratively, the face recognition module 10 includes a first bracket 11, a main board 12, and a sensor module 14, which are stacked. The first bracket 11 is located in the middle, and the main board 12 and the sensor module 14 are respectively arranged on two sides of the first bracket 11, so as to form a sandwich structure.

For convenience of understanding, first, the relationship between the three is described, and the first bracket 11 serves as a supporting structure of the whole face recognition module 10 for fixing the sensor module 14 and the main board 12. The sensor module 14 is used for taking an image of a target object, and the main board 12 is used for processing the image collected by the sensor module 14 to obtain face information of the target object. It should be understood that the main board 12 obtains the face information according to the image acquisition of the target object, which is common information processing in the prior art, and is specifically implemented by a processor or a circuit, and is not specifically limited in the embodiment of the present application.

Referring also to fig. 2, fig. 2 is an exploded view of the face recognition module 10. The first bracket 11 serves as a supporting structure of the whole face recognition module 10, and the first bracket 11 is a plate-shaped structure having two opposite surfaces, and the two surfaces respectively serve as assembling surfaces. In assembly, the sensor module 14 is fixed to one surface of the first bracket 11, and the main board 12 is fixed to the other surface of the first bracket 11.

It should be understood that the first bracket 11 provided in the embodiments of the present application may be made of a metal material or a non-metal material, and only needs to have a certain supporting strength. For example, the first bracket 11 may be made of different materials such as aluminum, stainless steel, plastic, resin, etc.

The main board 12 is used as a data processing component of the face recognition module, and a circuit capable of processing an image collected by the sensor module 14 is disposed thereon, and a specific circuit on the main board 12 is not specifically limited in this embodiment, and a conventional circuit for processing image data in the prior art may be used, and therefore details are not repeated in this embodiment.

When the main board 12 is connected to the first bracket 11, the main board 12 is detachably and fixedly connected to the first bracket 11. Specifically, different connection modes such as threaded connection, clamping connection and the like can be adopted.

For example, the first bracket 11 and the main board 12 may be connected by a first threaded connector 17, and a threaded hole corresponding to the first threaded connector 17 is provided on the first bracket 11. During assembly, the first screw-threaded connector 17 is screwed into the screw hole after passing through the main plate 12, thereby fixing the main plate 12 to the first bracket 11.

It should be understood that although fig. 2 shows that the main board 12 is locked on the first bracket 11 by two first threaded connectors 17 arranged diagonally, the number of the first threaded connectors 17 is not particularly limited in the embodiment of the present application, and the first threaded connectors 17 may be different in number, such as two, three, four, etc., as long as the main board 12 can be fixed on the first bracket 11.

As an alternative, when the main board 12 is fixedly connected to the first bracket 11, a space for accommodating electronic devices on the main board 12 is formed between the first bracket 11 and the main board 12. When the motherboard 12 is assembled, the side of the motherboard 12 on which the electronic device is disposed faces the first bracket 11, and when the motherboard 12 and the first bracket are fixed, the electronic device can be accommodated in the gap between the first bracket 11 and the motherboard 12. At this time, the first bracket 11 may be regarded as a protective case of the electronic device, thereby improving the safety of the electronic device.

The sensor module 14 is used for acquiring face information of a target object, and the sensor module 14 comprises a plurality of cameras to shoot two-dimensional images or three-dimensional images of the target object. When the human face image sensor is used, when an object is located in the image acquisition range of the sensor module 14, the sensor module 14 can acquire human face image information of the object, including two-dimensional images and three-dimensional images. The sensor module 14 may include various sensors and auxiliary devices for capturing images, and for example, the sensor module 14 may include electronic devices such as a projector, a first camera, a second camera, and a floodlight. The projector can emit projection light to project light for identifying the three-dimensional information of the target object to the target object. The first camera can shoot light spots formed by light rays projected to the target object by the projector so as to acquire three-dimensional information of the target object. The second camera can shoot a two-dimensional image of the target object to acquire color image information of the target object. The floodlight can provide illumination, and the brightness of the target object can be improved by irradiating the target object through the floodlight.

When the sensor module 14 is assembled with the first bracket 11, the sensor module 14 is detachably and fixedly connected with the first bracket 11. Specifically, the sensor module 14 and the first bracket 11 may be connected by different connection methods, such as a snap connection or a threaded connection.

The first bracket 11 and the sensor module 14 are connected by a screw connection. The face recognition module 10 further includes a second support 13, and the second support 13 is used as a support structure for the sensor module 14. During assembly, the sensor module 14 is fixed to the second bracket 13. Illustratively, the sensor module 14 is fixed to the second bracket 13 by means of bonding.

The second bracket 13 is stacked with the first bracket 11, and the second bracket 13 is located on a side of the first bracket 11 departing from the main board 12. When assembled, the second bracket 13 is detachably and fixedly connected with the first bracket 11. Illustratively, the second bracket 13 is connected with the first bracket 11 through a second threaded connector 18, and the first bracket 11 is provided with a threaded hole corresponding to the second threaded connector 18. The second screw connector 18 is screwed into the screw hole after passing through the second bracket 13, thereby fixing the second bracket 13 to the first bracket 11.

When the structure is adopted, the clamping force generated by the second threaded connecting piece 18 on the second support 13 directly acts on the second support 13 and does not act on the sensor module 14, so that the safety of the sensor module 14 during assembly is ensured.

It should be understood that although fig. 2 shows that the second bracket 13 is locked on the first bracket 11 by two second threaded connectors 18 arranged diagonally, the number of the second threaded connectors 18 is not particularly limited in the embodiment of the present application, and the second threaded connectors 18 may be different in number of two, three, four, etc., as long as the second bracket 13 can be fixed on the first bracket 11.

As an optional solution, in order to further improve the safety of the sensor module 14 during use, when the sensor module 14 is fixed on the second bracket 13, a shock-absorbing silicone is disposed between the sensor module 14 and the second bracket 13. The damping silica gel is used for providing the damping effect for sensor module 14, falls or when the collision appears in the accident of face identification module 10, can reduce the power that sensor module 14 received through the damping silica gel, improves sensor module 14's security.

It should be understood that the flexible circuit board 15 is only a specific implementation manner provided in the embodiment of the present application, and in the embodiment of the present application, the electrical connection structure between the main board 12 and the sensor module 14 is not specifically limited, for example, a conductive wire or a plug connector may also be used to implement the conductive connection between the two.

As shown in fig. 2, when the flexible circuit board 15 is used to connect the main board 12 and the sensor module 14, the flexible circuit board 15 has a U-shaped structure, and the flexible circuit board 15 spans across the first bracket 11. The first end of the flexible circuit board 15 and the main board 12 are located on the same side of the first bracket 11, and the first end of the flexible circuit board 15 is electrically connected with the main board 12; the second end of the flexible circuit board 15 and the sensor module 14 are located on the same side of the first bracket 11, and the second end of the flexible circuit board 15 is electrically connected with the sensor module 14.

In addition, the main board can control the floodlight and the projector to work. The information interaction between the main board and the projector, the first camera, the second camera and the floodlight is the existing common information interaction, and the main board obtains the face recognition information of the target object according to the images shot by the first camera and the second camera and is also the common information processing in the prior art, so the detailed description is not given in this embodiment.

The face recognition module 10 provided by the embodiment of the present application further includes a debugging board 16, and the debugging board 16 is electrically connected to the main board 12 and is used for debugging the face recognition module 10. Illustratively, the debug board 16 is provided with a USB interface and a debug port. The USB interface is connected with an external device to transmit data, and the external device can be connected with the face recognition module 10 through the debugging port to debug.

During assembly, the debugging plate 16 is detachably and fixedly connected with the first bracket 11. Illustratively, the adjustment plate 16 may be snap-fitted to the first bracket 11 or may be fixed to the first bracket 11 by a threaded connection. As shown in fig. 2, the debugging plate 16 is fixed on the first bracket 11 by two third screw connectors 19 (bolts or screws), but it should be understood that the number of the third screw connectors 19 is not particularly limited in the embodiment of the present application, and the number of the third screw connectors 19 may be two, three, etc. in different numbers.

It can be seen from the above description that the face identification module 10 that this application embodiment provided is through first support 11 as bearing structure, fixed sensor module 14 and mainboard 12 respectively, when keeping in repair or changing the part on the face identification module 10, only need with need change or the part of maintenance take off can, made things convenient for the maintenance to the module, when the part damages simultaneously, need not change whole face identification module, reduced extravagantly.

Referring to fig. 3, an embodiment of the present application further provides a face recognition device, which includes a housing, and the face recognition module 10 of any one of the above embodiments disposed in the housing. The casing serves as a support structure of the whole face recognition device, and is used for supporting and protecting the face recognition module 10.

The casing includes detachable backshell 20 and apron 30, and after face identification module 10 assembles in backshell 20, close on backshell 20 through apron 30 lid to seal face identification module 10 in the space that apron 30 and casing enclose.

As can be seen from the structure shown in fig. 3, the face recognition module 10 is directly wrapped by the shell, so that the whole face recognition device is small and exquisite, and can be conveniently used in cooperation with other devices for face payment. Exemplarily, the face recognition device can be conveniently clamped on an upper computer (a supermarket cash register), and the face recognition device can be assembled by adopting a smaller installation space due to a smaller size. In addition, the face recognition equipment can be directly provided with a tripod for supporting. It can be seen from the above examples that the face recognition device provided by the embodiment of the present application adopts a relatively compact structure, so that the size is relatively small, the occupied space is relatively small, and the face recognition device is convenient to disassemble and assemble.

Referring to fig. 4, fig. 4 is an exploded view showing a detailed structure of a face recognition device according to an embodiment of the present application. When the cover plate 30 is connected with the rear shell 20, the cover plate 30 is connected with the rear shell 20 in a sealing mode through the cover plate gum 50, so that the sealing effect of the face recognition device is improved, and dust is prevented from entering the shell.
