Description

Technical Field

[0001] This utility model relates to the field of facial recognition equipment technology, and in particular to the angle adjustment structure of a screenless facial recognition device. Background Technology

[0002] Screenless facial recognition devices refer to intelligent devices that do not have a display screen and achieve facial detection, recognition, and identity verification only through cameras, sensors, and algorithms. They are simple in structure, cost-controllable, and highly adaptable, and are widely used in security, attendance, access control, and other scenarios.

[0003] Existing screenless face recognition devices have a relatively simple angle adjustment structure, supporting only pitch or horizontal rotation. This makes it difficult to accurately adapt to users of different heights, and they cannot follow changes in user position in real time. The limited degree of adjustment affects the recognition success rate. Insufficient movement stability leads to recognition angle deviation. In temporary situations, the recognition device is cumbersome to disassemble and assemble, and has poor adaptability.

[0004] Therefore, to address the issues of limited adjustment freedom, insufficient movement stability, and cumbersome disassembly and assembly of existing screenless face recognition devices, an angle adjustment structure for screenless face recognition devices can be designed. Utility Model Content

The rear end of the mounting cover and the support plate are connected via an electric push rod. A device terminal is provided at the upper end of the inner wall of the mounting cover, and an adjustment cavity is opened on the rear side of the inner wall of the mounting cover. A bidirectional threaded rod is rotatably connected inside the adjustment cavity, and clamping plates are symmetrically threaded at both ends of the outer side of the bidirectional threaded rod.

[0007] Preferably, the device terminal is placed inside the mounting cover, and the bidirectional threaded rod is rotated to drive the clamping plate to move relative to each other and move the same distance. The device terminals of different specifications are clamped and fixed. The mounting base is installed in a suitable position, and the connecting ring rotates inside the mounting base, driving the support plate and the device terminal to rotate horizontally. The electric push rod extends and retracts to drive the mounting cover to adjust the tilt angle so that the device terminal can recognize the user's face.

[0008] Preferably, a rotating motor is fixedly connected to the upper end of the inner wall of the mounting base, and a gear is fixedly connected to the output shaft of the rotating motor. The rotating motor is electrically connected to the controller.

[0009] Preferably, the connecting ring is internally fixedly connected to an internal gear ring, which meshes with a gear.

[0012] Preferably, a rubber pad is fixedly connected to one end of the two clamping plates that are close to each other, and a protective cover is fixedly connected to the upper side of the front end of the mounting cover.

[0013] Preferably, heat sinks are fixedly connected to the upper and rear ends of the inner wall of the mounting cover. Multiple heat sinks are distributed at equal intervals, and heat dissipation holes are opened at both ends of the mounting cover.

[0014] The beneficial effects of this utility model are:

[0015] The angle adjustment structure of this screenless face recognition device uses a connecting ring and a clamping plate. The device terminal is placed inside the mounting cover, and rotating the bidirectional threaded rod drives the clamping plate to move relative to it, covering the same distance. This clamps and secures device terminals of different specifications, improving applicability. Installation, disassembly, and replacement are convenient and highly flexible.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of an angle adjustment structure for a screenless face recognition device, including a mounting base 1; it also includes a connecting ring 3 and a clamping plate 11. A controller 2 is fixedly connected to the upper end of the inner wall of the mounting base 1, and the connecting ring 3 is rotatably connected to the inner wall of the mounting base 1. A support plate 4 is fixedly connected to the upper end of the connecting ring 3, and two connecting seats 5 are fixedly connected to the upper end of the support plate 4. The connecting seats 5 located at the edge of the support plate 4 are rotatably connected to a mounting cover 6 via a rotating shaft. The rear end of the mounting cover 6 and the support plate 4 are connected via an electric push rod 7. A device terminal 8 is provided at the upper end of the inner wall of the mounting cover 6, and an adjustment cavity 9 is opened on the rear side of the inner wall of the mounting cover 6. A bidirectional threaded rod 10 is rotatably connected inside each adjustment cavity 9. Clamping plates 11 are symmetrically threaded at both ends of the threaded rod 10. In use, the device terminal 8 is placed inside the mounting cover 6. Rotating the bidirectional threaded rod 10 causes the clamping plates 11 to move relative to each other and travel the same distance. This clamps and fixes device terminals 8 of different specifications, improving applicability. Installation, disassembly, and replacement are convenient and highly flexible. The mounting base 1 is installed in a suitable position, and the connecting ring 3 rotates inside the mounting base 1, causing the support plate 4 and the device terminal 8 to rotate horizontally. The rotation speed and angle are precisely controlled. The electric push rod 7 extends and retracts to drive the mounting cover 6 to adjust the tilt angle so that the device terminal 8 can recognize the user's face. The movement is highly stable, with a large coverage area, improving the recognition success rate and demonstrating a high degree of intelligence.

[0024] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, a rotary motor 12 is fixedly connected to the upper end of the inner wall of the mounting base 1. A gear 13 is fixedly connected to the output shaft of the rotary motor 12. The rotary motor 12 is electrically connected to the controller 2. The controller 2 controls the rotary motor 12 to drive the gear 13 to rotate. An internal gear ring 14 is fixedly connected inside the connecting ring 3. The internal gear ring 14 and the gear 13 are meshed together. The gear 13 drives the internal gear ring 14 and the connecting ring 3 to rotate synchronously. The upper end of the connecting base 5 located in the support plate 4 is rotatably connected to the electric push rod 7. The output end of the electric push rod 7 is rotatably connected to the rear end of the mounting cover 6. The electric push rod 7 is electrically connected to the controller 2. The electric push rod 7 extends and retracts to drive the mounting cover 6 to adjust the tilt angle so that the device terminal 8 can recognize the user's face. The left end of the bidirectional threaded rod 10 extends to the outside of the mounting cover 6 and is fixedly connected to... A knob 15 is connected to the rear end of the clamping plate 11, which is slidably connected along the adjustment cavity 9. Rotating the knob 15 drives the bidirectional threaded rod 10 to rotate, causing the clamping plate 11 to move relative to each other and move the same distance. A rubber pad 16 is fixedly connected to one end of the two clamping plates 11 that is close to each other. A protective cover 17 is fixedly connected to the upper side of the front end of the mounting cover 6. The rubber pad 16 increases the clamping force and improves stability. The protective cover 17 avoids direct sunlight and ensures the clarity of the recognition image. Heat sinks 18 are fixedly connected to the upper end and rear end of the inner wall of the mounting cover 6. Multiple heat sinks 18 are evenly distributed. Heat dissipation holes 19 are opened at both ends of the mounting cover 6. The surface area of ​​the heat sinks 18 is increased to accelerate heat dissipation and improve the uniformity of heat flow. The heat dissipation holes 19 increase the air flow inside the mounting cover 6 and improve the heat dissipation and cooling efficiency.

[0025] During operation, the device terminal 8 is placed inside the mounting cover 6. Rotating the knob 15 drives the bidirectional threaded rod 10 to rotate, causing the clamping plate 11 to move relative to it and travel the same distance. This clamps and fixes the device terminals 8 of different specifications. The mounting base 1 is then installed in a suitable position. Rotating the motor 12 drives the gear 13 to rotate, which in turn drives the internal gear ring 14 and the connecting ring 3 to rotate synchronously. This causes the support plate 4 and the device terminal 8 to rotate horizontally. The rotation speed and angle are precisely controlled. The electric push rod 7 extends and retracts to drive the mounting cover 6 to adjust the tilt angle so that the device terminal 8 can recognize the user's face. This results in high movement stability, a large coverage area, improved recognition success rate, and a high degree of intelligence. The heat generated by the device terminal 8 during operation is transferred to the heat sink 18 and dissipated from the heat dissipation holes 19, improving heat dissipation and cooling efficiency.

[0026] Through the above steps, the clamping plate 11 clamps and fixes the device terminals 8 of different specifications, making installation, disassembly and replacement convenient. The connecting ring 3 drives the device terminal 8 to rotate horizontally, precisely controlling the rotation speed and angle. The electric push rod 7 extends and retracts to adjust the tilt angle to recognize the user's face, with high movement stability and a large coverage area, thus solving the problems of limited adjustment freedom of the angle adjustment structure of screenless face recognition devices, insufficient movement stability, and cumbersome disassembly and assembly of recognition devices.
