Description

Technical Field

[0001] The present invention relates to the technical field of face recognition devices, in particular to a face recognition device with expression acquisition function. Background Art

[0002] In the field of modern security, the security of gate face recognition systems is of vital importance. The recognition device's capture and analysis of natural changes in facial expressions has become one of the key bases for determining whether a face is alive. Compared with static photos or masks, real faces show unique dynamic characteristics and muscle movement patterns when expressions change. With the help of recognition devices to collect facial expression information, the face recognition system can more keenly perceive these differences, thereby effectively detecting forged faces and effectively preventing others from illegally breaking in using photos, videos, etc., greatly enhancing the security and anti-counterfeiting capabilities of the gate face recognition system.

[0003] However, during the wiring process of the recognition machine, after multiple wires are connected to the connectors, they are directly inserted into the poles. The multiple wires are easily entangled with each other. When the equipment is running, the wires generate heat due to the passage of current, and the entangled state hinders heat dissipation, resulting in a continuously high temperature at the wiring point. The insulation layer of the wiring is in a high temperature environment for a long time, which accelerates aging and becomes hard and brittle, and then cracks and breakage occur, leading to safety accidents such as short circuits and leakages, affecting the normal operation of the equipment; when the device is idle for a long time, due to lack of effective protection, a large amount of dust will accumulate on the screen and camera. When the equipment is activated again, the light transmittance of the lens deteriorates, the screen display clarity is affected, and the recognition effect is reduced; in addition, the recognition machine itself will generate a lot of heat during operation. If it cannot be dissipated in time and effectively, it will cause the internal temperature of the equipment to be too high, affecting the performance of electronic components, reducing the working efficiency and recognition accuracy of the recognition machine, and shortening the service life of the equipment.

[0024] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown, the heat dissipation structure 4 includes two connecting frames 401 detachably connected to the sunshade 302 and a filter 402 installed on the connecting frame 401. The filter 402 is located above the fan 404 to prevent debris from being blown onto the identification machine body 1 by the fan 404 and causing scratches. It can also prevent debris from damaging the fan 404, thereby playing a good protective role. A plurality of mounting rods 403 are fixedly connected to the connecting frame 401. A fan 404 is installed on every four mounting rods 403. A heat sink 408 is installed on the identification machine body 1. When the fan 404 is in operation, air blows toward the heat sink 408, which can quickly take away heat and improve the heat dissipation effect. To improve the working efficiency of the identification machine body 1, two mounting blocks 405 are slidingly connected in the sunshade 302, and the two mounting blocks 405 are respectively engaged with the two connecting frames 401. By engaging the mounting blocks 405 with the connecting frames 401, the stability between the connecting frames 401 and the sunshade 302 is enhanced, the reliability of the entire heat dissipation protection is guaranteed, and a good working environment for the identification machine body 1 is maintained.

A first screw rod 407 is rotatably connected in the sunshade 302, and the first slide bar 406 is threadedly connected to the first screw rod 407.

[0025] Specifically, such as Figure 1 、 Figure 2 、 Figure 8 、 Figure 10 and Figure 11As shown, the mounting structure 7 includes a mounting column 701 mounted on the connecting seat 2 and a vertical rod 702 mounted on the mounting column 701, and a connecting cover 703 is detachably connected to the vertical rod 702. The connecting cover 703 is detachably connected, which increases the operating space, facilitates the arrangement of internal wiring, and ensures that the wiring is regular and orderly. Two positioning plates 704 are fixedly connected to the vertical rod 702, one of which is threadedly connected to a knob 705. The partition structure 8 includes two guide shafts 801 fixedly connected to the vertical rod 702 and an adjustment block 802 slidably connected to the guide shaft 801. A sliding shaft 803 is slidably connected, a mounting plate 804 is fixedly connected to the sliding shaft 803, a second spring 805 is fixedly connected between the mounting plate 804 and the adjusting block 802, a connecting shaft 806 is rotatably connected to the sliding shaft 803, a fixing rod 807 is fixedly connected to the connecting shaft 806, a rubber pad 808 is fixedly connected to the fixing rod 807, and the provision of the rubber pad 808 increases the friction force, further improving the fixing effect, a second screw rod 809 is threadedly connected to the adjusting block 802, the second screw rod 809 conflicts with the vertical rod 702, and the second screw rod 809 conflicts with the vertical rod 702, thereby improving the stability of the adjusting block 802.

[0026] When the present invention is in use, when installing the identification machine body 1, first pass the wiring of the identification machine body 1 through the through hole on the vertical pole 702, and then place each wiring in the placement groove of the adjustment block 802. The adjustment block 802 can separate the wiring, effectively preventing multiple wiring from being entangled with each other, thereby preventing the entanglement from affecting the heat dissipation of the equipment. Then pull the fixing rod 807 to drive the sliding shaft 803 to slide, and the sliding shaft 803 will drive the mounting plate 804 to slide. During this process, the mounting plate 804 causes the second spring 805 to contract. When the fixing rod 807 moves to a certain position, rotate the fixing rod 807 to rotate it to a horizontal state through the connecting shaft 806. At this time, release the fixing rod 807, and it will fix the wiring under the action of the second spring 805. The second screw rod 809 is rotated so that the second screw rod 809 contacts the vertical rod 702 to fix the position. After the installation is completed, the connecting cover 703 is connected with the positioning plate 704, and the knob 705 is passed through the hole reserved for the connecting cover 703 and matched with the threaded hole on the positioning plate 704 to complete the installation of the connecting cover 703. The connecting cover 703 is detachable and connected, which increases the operating space, facilitates the arrangement of the internal wiring, ensures that the wiring is regular and orderly, and provides a guarantee for the stable operation of the identification machine body 1. In daily use, the heat emitted by the recognition machine body 1 will be conducted to the heat sink 408. At this time, the fan 404 is started. When the fan 404 is running, it blows air to the heat sink 408, which can quickly take away the heat, improve the heat dissipation effect, and thus improve the working efficiency of the recognition machine body 1. At the same time, the fan 404 can also blow away dust to prevent dust from adhering to the screen and camera, avoiding adverse effects on the display and camera effects. The filter 402 is located above the fan 404, which can prevent debris from being blown onto the recognition machine body 1 by the fan 404 and causing scratches, and can also prevent debris from damaging the fan 404, playing a role. Good protection effect. When the filter 402 needs to be replaced, the first screw rod 407 is inserted with an inner hexagonal wrench to rotate. The first screw rod 407 drives the first slide rod 406 to slide through the thread. The first slide rod 406 drives the two mounting blocks 405 to slide, so that the mounting blocks 405 are no longer engaged with the connecting frame 401. The connecting frame 401 can be removed to replace the filter 402. The engagement of the mounting blocks 405 with the connecting frame 401 enhances the stability between the connecting frame 401 and the sunshade 302, thereby ensuring the reliability of the entire heat dissipation protection and maintaining a good working environment of the identification machine body 1. The rotation of the motor 312 drives the shaft 301 to rotate, and the shaft 301 drives the sunshade 302 to move. In this process, the fixed shaft 304 drives the transmission gear 308 to cooperate with the rack 307, so that the fixed shaft 304 drives the sunshade 302 to rotate ninety degrees. At the same time, the torsion spring 305 resets. After the fixed shaft 304 rotates, the stopper 309 is blocked by the fixed block 310. The cooperation of the stopper 309 and the fixed block 310 plays a limiting role, accurately controlling the rotation position of the sunshade 302 to ensure the orderly progress of subsequent actions. The sunshade 302 continues to be rotated so that the sunshade 302 rotates two hundred and seventy degrees. At this time, the sunshade 302 and the connecting plate 303 block the screen and the camera. At the same time, the rotation of the shaft 301 drives the first bevel gear 311 to rotate, and the first bevel gear 311 drives the second bevel gear 60 9 rotates, the second bevel gear 609 drives the installation shaft 607 to rotate. When the installation shaft 607 rotates, the driving shaft 606 on the slider 605 rolls with the spiral groove 608 to make the slider 605 slide toward the rotating shaft 301, and the slider 605 drives the adjusting rod 604 to slide. The adjusting rod 604 will drive the second slide bar 603, and the second slide bar 603 drives the slide frame 602 to move, and finally drives the sealing ring 601 to move. When the sunshade 302 rotates 270 degrees, the sealing ring 601 just conflicts with the sunshade 302 and the connecting plate 303, effectively preventing the gap between the connecting plate 303, the sunshade 302 and the identification machine body 1 from being too large to cause dust to enter. With the cooperation of the sunshade 302 and the connecting plate 303, the screen and camera of the identification machine body 1 are fully protected to prevent dust from adhering when idle for a long time, ensuring that the identification machine body 1 can operate normally and stably when used again.
