Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] In this embodiment of the invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. They can be mechanical or electrical connections.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0044] like Figures 1 to 7 As shown, this utility model embodiment provides an auxiliary device, including a storage platform 100, a lifting platform 200, a visual inspection device 300, a first driving device 400, a second driving device 500, and a base 700.

[0045] The platform 100 is located at the top of the lifting platform 200. The visual detection device 300 is located on the lifting platform 200, specifically on the side of the lifting platform 200 facing the human body, to monitor the user's face in real time. The first drive device 400 is located on the lifting platform 200. Specifically, the lower end of the lifting platform 200 is provided with a downward-facing cavity 210. The base 700 extends into the cavity 210. The second drive device 500 is located on the base 700 and is housed in the cavity 210 to prevent the second drive device 500 from being exposed. This reduces contamination from dust and other pollutants, thus improving service life, reducing cleaning work, and making the overall shape more aesthetically pleasing, which greatly improves the user experience.

[0046] Furthermore, the visual detection device 300 is used to identify the movement of a human face and output a signal, the platform 100 can rotate around its center, the first drive device 400 is configured to drive the platform 100 to rotate according to the signal output by the visual detection device 300, and the second drive device 500 is configured to drive the lifting platform 200 to move up and down according to the signal output by the visual detection device 300.

[0047] It should be understood that the shelf 100 is used to place electronic products such as desktop computer monitors, laptops, or tablets.

[0048] Before use, the user's facial information is first recorded and recognized by the visual inspection device 300 so that the visual inspection device 300 can recognize the user information in subsequent operations.

[0049] Specifically, the auxiliary device is equipped with a main control chip (not shown in the figure) connected to the visual inspection device 300. The main control chip is connected to a mobile APP, such as a mobile phone or tablet, via a Bluetooth module (not shown in the figure). Users can enter their own facial information in the APP.

[0050] More specifically, during sampling, the visual detection device 300 collects facial information from the user at a sampling rate of 20 frames per second. A total of 60 facial images can be collected within 3 seconds. The 60 facial images are sampled according to a normal distribution, with 8 images sampled. The information is then sent to the main control chip. The main control chip performs preprocessing and feature recognition on the collected images, and then compares the real-time facial features with the recorded features. After 8 collections and comparisons, if the average confidence level is >85%, the real-time facial information is considered to match the recorded information, thereby realizing the "identifying the owner" function and ensuring the accuracy of facial recognition.

[0051] When in use, the visual detection device 300 monitors the user's facial movements. When the user's head turns left or right, the visual detection device 300 outputs a signal based on the user's facial movements, controlling the first drive device 400 to drive the platform 100 to rotate the electronic products placed on it in the direction of the user's facial movement. This improves the flexibility of the viewing angle and can adapt to different scenarios, such as facilitating communication with other people or displaying work content. It can meet the needs of viewing from different angles, avoid screen reflections interfering with vision, and reduce eye fatigue caused by poor viewing angles.

[0052] The visual detection device 300 monitors the user's facial movements and can also control the second drive device 500 to drive the lifting platform 200 to move the storage platform 100 up and down, so that the screen is always at eye level with the user's eyes, avoiding the user from looking up or down at the screen for a long time, which can cause neck fatigue, injury and other problems.

[0053] The auxiliary device can also record the user's height, habitual sitting height, and head tilt angle during work, so that the user can adjust the height and angle of the electronic product according to their habits when using it again.

[0054] In one embodiment, such as Figure 3 As shown, two second drive devices 500 are arranged at intervals along the length of the lifting platform 200 and staggered back and forth along the width of the lifting platform 200, so as to ensure that the force is more stable when the platform 100 is driven to rise and fall.

[0055] In some specific embodiments, such as Figure 3 and 4 As shown, the second drive device 500 includes a lifting frame 510 and a drive assembly 520. At least one lifting frame 510 is provided. In this embodiment, two are preferred. The two lifting frames 510 are arranged at intervals along the length direction of the lifting platform 200 to ensure the stability of the lifting frame 510.

[0056] Specifically, the lifting frame 510 includes a swing arm 511 and a connecting seat 512. There are two connecting seats 512 arranged at intervals, one above the other, along the width direction of the lifting platform 200. The connecting seat 512 is provided with a guide hole 5121 arranged along its length direction. Specifically, the upper connecting seat 512 is connected to the lifting platform 200, and the lower connecting seat 512 is fixedly connected to the base 700.

[0057] Furthermore, two swing arms 511 are arranged on one side of the connecting seat 512, and the two swing arms 511 are arranged crosswise, with their intersections rotatably connected. Specifically, their intersections are connected by a pivot (not shown in the figure). Furthermore, each end of the swing arm 511 is provided with a first connecting shaft 530 and a second connecting shaft 540 arranged along the length of the lifting platform 200. The first connecting shafts 530 on the two swing arms 511 are vertically aligned, and the first connecting shaft 530 extends into the corresponding guide hole 5121 and is movably connected to the guide hole 5121. The second connecting shaft 540 is connected to the corresponding connecting seat 512. It should be noted that when there are two lifting frames 510, the two ends of the first connecting shaft 530 and the second connecting shaft 540 are respectively connected to the corresponding swing arms 511 on the two lifting frames 510 to improve the stability of the structure and reduce the number of components used.

[0058] Furthermore, the drive assembly 520 can drive the lower first connecting shaft 530 to move along the opening direction of the guide hole 5121, thereby driving the upper connecting seat 512 to move up and down. In other words, the drive assembly 520 drives the lower first connecting shaft 530 to control the two swing arms 511 to converge or expand, thereby controlling the lifting of the lifting platform 200. This has the advantages of high precision and high stability.

[0059] In some more specific embodiments, such as Figure 3 and 4 As shown, the drive assembly 520 includes a first motor 521, a lead screw 522, and a mounting base 523. The lead screw 522 is arranged along the width direction of the lifting platform 200. Specifically, both ends of the lead screw 522 are connected to the base 700 through bearing seats, and the lead screw 522 is located between the two lifting frames 510. Furthermore, a nut 524 is disposed on the lead screw 522, and the mounting base 523 is connected to the nut 524. The first connecting shaft 530 located below is connected to the mounting base 523. The first motor 521 is driven to one end of the lead screw 522. The first motor 521 is preferably a DC geared motor. That is, the first motor 521 drives the lead screw 522 to rotate, thereby driving the first connecting shaft 530 connected to the mounting base 523 to move along the opening direction of the guide hole 5121, so as to control the two swing arms 511 to converge or expand.

[0060] In one embodiment, such as Figure 4As shown, a groove 5122 corresponding to and communicating with the guide hole 5121 is provided on one side of the connecting seat 5122. A roller 531 movably connected to the groove 5122 is provided on the first connecting shaft 530. The cooperation between the roller 531 and the groove 5122 ensures the stability and smoothness of the movement of the first connecting shaft 530, avoids the generation of noise, and improves the service life of the first connecting shaft 530.

[0061] In one embodiment, such as Figure 2 , 5 As shown in Figure 6, a roller 600 is provided between the storage platform 100 and the lifting platform 200. The roller 600 is horizontally arranged and movably connected to the storage platform 100 and the lifting platform 200. Specifically, the lower end of the storage platform 100 and the upper end of the lifting platform 200 are respectively provided with mounting grooves 610 arranged along the rotation path of the storage platform 100. The two mounting grooves 610 of the storage platform 100 and the lifting platform 200 form a cavity, and the cavity is filled with rollers 600 to ensure the stability of the rollers 600 during operation.

[0062] More specifically, multiple mounting slots 610 are provided. Among them, an annular mounting slot 610 is provided at the middle of the lower end of the platform 100 and the upper end of the lifting platform 200, which is arranged around the center of the two to improve the load-bearing capacity of the middle of the platform 100. In order to maintain the balance of the platform 100, arc-shaped mounting slots 610 are symmetrically arranged on both sides of the annular mounting slot 610, which are arranged along the rotation path of the platform 100. The arc of the arc-shaped mounting slot 610 is preferably 20° to 45°. The horizontally arranged rollers 600 can increase the contact area with the platform 100 to improve the load-bearing capacity and stability of the platform 100.

[0063] In some specific embodiments, such as Figure 2 and 5 As shown, the first driving device 400 includes a second motor 410 and a fixed base 420. A connecting part 120 is provided at the lower center of the platform 100. A hollow opening 220 corresponding to the connecting part 120 is provided on the lifting platform 200. The fixed base 420 is provided on the inner bottom wall of the lifting platform 200. The second motor 410 is vertically mounted on the fixed base 420. The shaft of the second motor 410 passes through the hollow opening 220 and is connected to the connecting part 120. That is, the second motor 410 drives the platform 100 to rotate, thereby driving the electronic products on the platform 100 to rotate. Specifically, the second motor 410 is preferably a servo motor.

[0064] In one embodiment, such as Figure 5 and 6As shown, the upper end of the lifting platform 200 is provided with an arc-shaped limiting hole 230 along the rotation path of the storage platform 100. The arc of the arc-shaped limiting hole 230 is preferably 20° to 45°. The storage platform 100 is provided with a limiting plate 110 that extends into the arc-shaped limiting hole 230. That is, the rotation angle of the storage platform 100 is controlled by the cooperation of the arc-shaped limiting hole 230 and the limiting plate 110.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
