For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0044] like Figures 1 to 7 As shown, an embodiment of the present invention 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] Among them, the storage table 100 is arranged at the upper end of the lifting platform 200, and the visual detection device 300 is arranged on the lifting platform 200. Specifically, the visual detection device 300 is located on the side of the lifting platform 200 facing the human body to monitor the user's face in real time. The first driving device 400 is arranged on the lifting platform 200. Specifically, the lower end of the lifting platform 200 is provided with a cavity 210 with an opening facing downward, and the base 700 extends into the cavity 210. The second driving device 500 is arranged on the base 700 and accommodated in the cavity 210 to avoid the second driving device 500 from being exposed, which can reduce contamination by pollutants such as dust, so as to increase the service life, reduce cleaning work, and make the overall shape more beautiful, which can greatly improve the user experience.

[0046] Furthermore, the visual detection device 300 is used to identify the facial movement of the human body and output a signal. The storage platform 100 can rotate around its center. The first driving device 400 is configured to drive the storage platform 100 to rotate according to the signal output by the visual detection device 300. The second driving 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 storage table 100 is used to place electronic products such as a desktop computer display, a notebook or a tablet.

[0048] Before use, the visual detection device 300 is first used to input and identify the user's facial information so that the visual detection device 300 can identify the user information during subsequent operation.

[0049] Specifically, the auxiliary device is provided with a main control chip (not shown in the figure) connected to the visual detection device 300. The main control chip is connected to the mobile APP, such as the APP signal on the mobile phone, tablet and other electronic products through a Bluetooth module (not shown in the figure). The user can enter his or her own facial information in the APP.

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

[0051] When in use, the visual detection device 300 will monitor the user's facial movements. When the user's head turns left and right, the visual detection device 300 outputs a signal according to the user's facial movements, controls the first drive device 400 to drive the storage table 100 to drive the electronic products placed thereon to rotate in the direction of the user's facial rotation, so as to improve the flexibility of the viewing angle and adapt to the use of different scenarios, such as facilitating communication of work or display of work content to other people, meeting the needs of viewing at different angles, avoiding interference of screen reflection on vision, etc., and reducing the occurrence of eye fatigue caused by poor viewing angles.

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

[0053] The auxiliary device can also record the user's height, habitual sitting height and the pitch angle of the head when working, 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, if Figure 3 As shown, two second driving devices 500 are arranged at intervals along the length direction of the lifting platform 200, and are staggered front and back along the width direction of the lifting platform 200, so as to ensure that the force is more stable when driving the storage platform 100 to rise and fall.

The cooperation between the roller 531 and the groove 5122 can ensure the stability and smoothness of the movement of the first connecting shaft 530, avoid the generation of noise, and improve the service life of the first connecting shaft 530.

[0061] In one embodiment, if Figure 2 , 5 As shown in 6, rollers 600 are arranged between the storage table 100 and the lifting platform 200.
