DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the present invention is described in detail with reference to schematic diagrams. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included. Embodiment 1 like Figure 1-7 As shown, a computer gesture recognition device proposed by the present invention includes a mounting unit 1, a gesture recognition unit 2, a driving mechanism 3, a cleaning mechanism 7, a driving unit, and a moving mechanism 8; The mounting unit 1 includes a shell 101, a rotating frame 102 rotatably arranged in the shell 101, and a mounting frame 104 arranged in the shell 101; the gesture recognition unit 2 is arranged on the rotating frame 102; the driving mechanism 3 is arranged on the mounting frame 104 and the output end is connected to the rotating frame 102; the cleaning mechanism 7 is slidably arranged in the shell 101 and the output end is slidably connected to the gesture recognition unit 2; the driving unit is arranged on the driving mechanism 3 and is drivingly connected to the cleaning mechanism 7; the moving mechanism 8 is arranged in the shell 101 and is used to drive the cleaning mechanism 7 to move in the vertical direction.

[0023] The driving mechanism 3 includes a mounting shell 301 arranged in the housing 101, a driving motor 302 arranged on the mounting shell 301, a driving gear 303 connected to the output end of the driving motor 302 and arranged on the rotating frame 102, a reversing gear 304 rotatably arranged on the mounting shell 301 and meshingly connected with the driving gear 303, and a driven gear 305 rotatably arranged on the mounting shell 301 and meshingly connected with the driving gear 303; the driven gear 305 is drivingly connected to the pulley 702 through a driving unit; the driving motor 302 drives the driving gear 303 to rotate, and the driving gear 303 drives the driven gear 305 to rotate through the reversing gear 304, so that the driven gear 305 can be rotated in the same direction as the driving gear 303 and can rotate at an increased speed, thereby improving the energy storage efficiency of the energy storage mechanism 4.

[0024] In this embodiment, the driving motor 302 drives the active gear 303 to rotate, and the active gear 303 can directly drive the rotating frame 102 to rotate, so that the gesture recognition unit 2 rotates, so that the gesture recognition camera 202 and the depth recognition camera 203 are exposed to perform gesture recognition. When it is not needed, the driving motor 302 drives the rotating frame 102 to reset, so that the gesture recognition unit 2 faces the direction of the cleaning mechanism 7 and is cleaned once, so that the gesture recognition unit 2 is in a clean state each time it is used, thereby ensuring the accuracy of the measurement.

[0025] In the present invention, when not in use, the infrared sensor 201 faces the detection port 1011, and low-power monitoring is performed through the infrared sensor 201. When it is needed, just put your hand into the recognition range of the infrared sensor 201. When the infrared sensor 201 recognizes that there is an object, it will drive the rotating frame 102 to rotate through the driving mechanism 3, so that the rotating frame 102 drives the infrared sensor 201 to move upward, and drives the gesture recognition camera 202 and the gesture recognition camera 202 to align with the detection port 1011, so as to recognize the current gesture and feed back the recognition result to the computer, and the computer performs corresponding operations according to the corresponding gesture.

[0026] Compared with the real-time monitoring by the gesture recognition camera 202 and the depth recognition camera 203 in the prior art, the present invention adopts a low-power infrared sensor 201 for monitoring, which can greatly reduce energy consumption. When the gesture recognition camera 202 and the depth recognition camera 203 are not in use, they are stored in the shell 101 and cleaned by the cleaning mechanism 7. The gesture recognition camera 202 and the depth recognition camera 203 can be protected and the clarity of the shooting of the gesture recognition camera 202 and the depth recognition camera 203 can be ensured, thereby ensuring the recognition accuracy each time it is used, will not be disturbed by dust and dirt, and can extend the service life.

[0027] Embodiment 2 like Figure 1-7 As shown, a computer gesture recognition device proposed by the present invention, compared with the first embodiment, the gesture recognition unit 2 in this embodiment includes an infrared sensor 201 arranged on the rotating frame 102, a gesture recognition camera 202 arranged on the rotating frame 102 and perpendicular to the infrared sensor 201, and a depth recognition camera 203 arranged on the rotating frame 102 and parallel to the gesture recognition camera 202; the infrared sensor 201 is control-connected to the driving mechanism 3.

[0028] In this embodiment, the gesture recognition camera 202 provides high-resolution color information, while the depth recognition camera 203 provides spatial depth information. Combining the two can obtain more comprehensive environmental data. The depth recognition camera 203 can help identify and track objects more accurately, especially in complex backgrounds or changing lighting conditions. In gesture recognition, the depth recognition camera 203 can help more accurately determine the user's position and action, thereby improving the naturalness and accuracy of the interaction. In the case where an object or person is partially blocked, the depth recognition camera 203 can better understand the three-dimensional structure of the scene and help the system predict the shape and position of the blocked part.

[0029] Embodiment 3 like Figure 1-7 As shown, a computer gesture recognition device proposed by the present invention, compared with embodiment one or embodiment two, the cleaning mechanism 7 in this embodiment includes a sliding frame 701 slidably arranged in the shell 101, two pulleys 702 are provided and both are rotatably arranged on the sliding frame 701, a cleaning belt 703 is arranged on the pulley 702 and is slidably connected to the gesture recognition camera 202 and the depth recognition camera 203, a friction brush 704 is rotatably arranged on the sliding frame 701 and is slidably connected to the cleaning belt 703, a belt transmission component 2 705 is arranged on the pulley 702 for driving the friction brush 704 to rotate, and a feeding comb is arranged on the sliding frame 701 and is slidably connected to the friction brush 704.

[0030] The moving mechanism 8 includes a pushing plate 801 which is arranged on the rotating frame 102 and has a structure of a combination of a circle and a straight line, a lower pressing frame 802 which is arranged on the sliding frame 701 and is slidably connected to the pushing plate 801, a guide shaft 803 which is arranged on the sliding frame 701 and is slidably connected to the shell 101, and an elastic member 804 which is arranged on the guide shaft 803 and has two ends respectively connected to the shell 101 and the sliding frame 701; when the rotating frame 102 rotates, it will drive the pushing plate 801 to rotate, and the cross section of the pushing plate 801 is a combination of a circle and a straight line, so that the arc side of the pushing plate 801 contacts the lower pressing frame 802, and the distance from the arc side of the pushing plate 801 to the center of the circle is greater than the distance from the straight line side to the center, so that the lower pressing frame 802 is pushed to The lower pressure frame 802 pushes the sliding frame 701 to move downward, so that the cleaning mechanism 7 is exposed to the space where the rotating frame 102 rotates. When the rotating frame 102 is reset, the gesture recognition camera 202 and the depth recognition camera 203 are facing the direction of the cleaning mechanism 7. At this time, the straight side of the pushing plate 801 contacts the lower pressure frame 802, so that the elastic member 804 can push the sliding frame 701 to move upward, so that the cleaning mechanism 7 contacts the gesture recognition camera 202 and the depth recognition camera 203.

When the rotating frame 102 is rotated into place, the straight side of the push plate 801 contacts the lower pressure frame 802, so that the lower pressure frame 802 moves upward, thereby causing the sliding frame 701 to move upward, driving the pulley 702 and the cleaning belt 703 to move upward, and the cleaning belt 703 contacts the gesture recognition camera 202 and the depth recognition camera 203. At the same time, due to the upward movement of the sliding frame 701, the push rod 601 moves upward, so that the unlocking mechanism 6 releases the energy storage mechanism 4. The energy stored in the energy storage mechanism 4 is released by the limiting mechanism, and is transmitted to the pulley 702 through the transmission mechanism 5 to rotate the pulley 702, and the pulley 702 drives the cleaning belt 703 to rotate, so that the cleaning belt 703 cleans the dirt on the gesture recognition camera 202 and the depth recognition camera 203, and then drives the friction brush 704 to rotate through the belt transmission component 2 705, so that the dirt on the cleaning belt 703 can be wiped off by the friction brush 704, so that the cleaning belt 703 can be cleaned, and the dirt remaining on the friction brush 704 is scraped off by the cleaning comb, so that the friction brush 704 can be cleaned, and a sealing plate 103 is provided on the shell 101, and after opening the sealing plate 103, the fallen dirt can be easily cleaned.

The unidirectional transmission unit 404 can make the rotating disk 402 rotate only counterclockwise, while the clockwise rotation force is unloaded through the unidirectional transmission unit 404, which can prevent the rotating disk 402 from rotating when the rotating frame 102 is reset; the unidirectional transmission unit 404 can be realized by a ratchet pawl structure; the clamping frame 901 is pushed downward by the elastic member 903, so that the clamping frame 901 drives the sliding roller 902 to insert into the one-way inclined groove 4021, and one side of the one-way inclined groove 4021 is an inclined structure, so that the sliding roller 902 can move upward along the inclined structure, so that the rotating disk 402 can rotate counterclockwise, and when it rotates clockwise, it is stuck by the clamping frame 901 to prevent it from reversing.
