Description

Technical Field

[0001] The utility model belongs to the technical field of face recognition devices, and in particular relates to a face recognition device capable of switching swing modes. Background Art

[0002] Facial recognition devices primarily identify people based on facial features. Every face has unique physical characteristics, such as the distance between the eyes, the height of the nose bridge, the shape of the mouth, and facial contours. Facial recognition devices capture these features and compare them with pre-stored facial information to determine whether they are the same person.

[0003] In actual application scenarios, existing facial recognition devices have certain limitations if the heights of users vary greatly, including children, adults, and disabled people in wheelchairs. Therefore, we need to improve them. Utility Model Content

[0005] As a preferred embodiment of the present invention, the face recognition display is a quarter-sector structure, and the output end of the driving mechanism intersects with the arc edge of the face recognition display.

[0006] As a preferred embodiment of the present invention, a receiving cavity communicating with the groove is further provided in the operation panel, and the driving mechanism is installed in the receiving cavity.

[0008] As a preferred embodiment of the present invention, the output end of the servo motor is connected to a gear, the arc edge of the face recognition display is provided with a rack, and the servo motor is meshed with the rack through the gear.

[0009] As a preferred embodiment of the present invention, the driving mechanism includes a plastic positioning spring piece, a limiting groove is opened at the fan-shaped arc edge of the face recognition display, the plastic positioning spring piece is installed on the lower end inner wall of the accommodating cavity, and the plastic positioning spring piece is against the position of the limiting groove.

[0010] As a preferred embodiment of the present invention, the limiting groove includes a notch, the notch is provided at a fan-shaped arc edge of the face recognition display, and the plastic positioning spring rests in the notch.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model is provided with a servo motor, which drives the gear to rotate, the gear is engaged with the rack, and the rack is installed on the face recognition display, so the face recognition display is automatically swung by the servo motor;

[0013] The plastic positioning spring is primarily retained within the recesses by a convex structure. After manually swinging the facial recognition device, the convex structure on the plastic positioning spring slides over the multiple recesses sequentially through elastic deformation. When the manual swinging of the facial recognition device stops, the convex structure of the plastic positioning spring is retained within the recesses, thereby increasing the friction of the swinging facial recognition device.

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0022] Example 1, as Figure 1 - Figure 3As shown, an embodiment of the present invention provides a face recognition device with switchable swinging mode, including an operation panel 1 and a face recognition display 2. The operation panel 1 is provided with a groove 3 adapted to the face recognition display 2, and the face recognition display 2 is arranged in the groove 3. The operation panel 1 is also connected to a driving mechanism for driving the face recognition display 2 to swing.

[0023] As a preferred embodiment of the present invention, the face recognition display 2 is a quarter-sector structure, and the output end of the drive mechanism intersects with the arc edge of the face recognition display 2; the operation panel 1 is further provided with a receiving cavity 4 connected to the groove 3, and the drive mechanism is installed in the receiving cavity 4; the drive mechanism includes a servo motor 5, which is installed on the inner wall of the receiving cavity 4 of the operation panel 1, and the output end of the servo motor 5 is connected to the arc edge of the face recognition display 2; the output end of the servo motor 5 is connected to a gear 6, and a rack 7 is provided on the arc edge of the face recognition display 2, and the servo motor 5 is meshed with the rack 7 through the gear 6;

[0024] The face recognition display 2 is connected to a shaft, and the face recognition display 2 is rotatably connected to the groove 3 of the operation panel 1 through the shaft;

[0025] In Example 1, when the driving mechanism is installed, the face recognition device is swung by driving the servo motor 5. The specific operation is: when the output end of the servo motor 5 drives the gear 6 to rotate, the gear 6 engages with the rack 7, and the gear 6 drives the rack 7 to swing. When the rack 7 swings, the face recognition display 2 swings.

[0026] Example 2, as Figure 3 - Figure 5 As shown, an embodiment of the present invention provides a face recognition device with switchable swinging mode, including an operation panel 1 and a face recognition display 2. The operation panel 1 is provided with a groove 3 adapted to the face recognition display 2, and the face recognition display 2 is arranged in the groove 3. The operation panel 1 is also connected to a driving mechanism for driving the face recognition display 2 to swing.

[0027] As a preferred embodiment of the present invention, the outer surface of the fan-shaped arc edge of the face recognition display 2 is provided with a plurality of notches 8 arranged in sequence against each other, and the inner wall of the lower end of the groove 3 is connected with a plastic positioning spring 9, and a convex structure adapted to the notch 8 is formed on the plastic positioning spring 9, and the convex structure of the plastic positioning spring 9 abuts against one of the notches 8;

[0028] In Example 2, the facial recognition device is manually swung without a drive mechanism. Specifically, the plastic positioning spring 9 is primarily retained within the recess 8 by a convex structure. After the facial recognition device is manually swung, the convex structure of the plastic positioning spring 9 sequentially slides and retains position on the multiple recesses 8 through elastic deformation. When the manual swinging of the facial recognition device stops, the convex structure of the plastic positioning spring 9 remains retained within the recess 8, thereby increasing the frictional force of the swinging facial recognition device.
