[0002] A study desk is a new, scientific, user-friendly, and practical learning aid, suitable for a wide range of users. It features height adjustment and desktop tilting functions. The study desk is a tool developed through in-depth research in ergonomics, biomechanics, and human physiology, combined with principles of human vision, color theory, and psychology. It has undergone countless data collections, experiments, and verifications. A study desk is a completely different concept from a traditional desk. Some study desks also integrate tablets or learning tablets for the convenience of students.

[0003] The tablets or learning tablets on existing study desks either have a built-in wireless projection module or do not have wireless projection functionality. Those with a built-in wireless projection module can only be used on that device, while those without wireless projection functionality require an external wireless projection device. External wireless projection devices involve many connection cables, and when adjusting or moving them, they drag each other with the tablet or learning tablet, making them inconvenient to store.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figures 1-8 As shown, the present invention provides a wireless screen projection learning desk, including a desk body 16. A display device 2 is provided on the desk body 16, and a wireless screen projection module 7 is detachably provided on the display device 2. A folding mechanism is provided on the mounting side of the display device 2, and the folding mechanism is provided on a bookshelf shelf 1. The bookshelf shelf 1 is mounted on the desk body 16. A back panel 11 for enclosing its internal structure is provided on the back of the display device 2, and a placement slot 15 for accommodating the wireless screen projection module 7 is provided. An audio / video plug 13 and a power plug 12 for connecting to the wireless screen projection module 7 are provided on the side of the display device 2 near the placement slot 15. The wireless screen projection module 7 is provided with an interface for use with the audio / video plug 13 and the power plug 12.

[0028] Specifically, the display device 2 can be one of a monitor, tablet computer, learning tablet, etc.; the audio / video plug 13 is preferably an HDMI plug, but other video cable plugs can be selected as needed; the power plug 12 is preferably a Type-C plug, but other plugs can be selected as needed; when the audio / video plug 13 or the power plug 12 is plugged into the corresponding interface, the other plug is also plugged into the other interface. At this time, one side and the bottom of the wireless projection module 7 are respectively attached to the side and the bottom of the placement slot 15; the bottom of the placement slot 15 is parallel to the insertion direction of the audio / video plug 13 and the corresponding interface, which ensures the convenience of plugging. This utility model provides the wireless projection function of the display device 2 while also allowing the wireless projection module 7 to be detached and connected to other devices, effectively improving the utilization rate of the device; by setting the audio / video plug 13 and the power plug 12 on the display device 2 to be plugged into the wireless projection module 7, the display device 2 and the wireless projection module 7 maintain an integral structure; by setting the folding mechanism, not only is it convenient to store the display device 2, but it is also convenient to support the display device 2.

[0029] To improve the connection performance between the wireless projection module 7 and the display device 2, this invention provides a connection unit between the placement slot 15 and the wireless projection module 7. Specifically, the connection unit includes a magnet 14 and an iron plate that work together. The magnet 14 is fixedly connected to the placement slot 15, and the iron plate is fixedly connected to the wireless projection module 7. In this way, the magnet 14 and the iron plate can position the wireless projection module 7 in the placement slot 15, improving the connection stability between the wireless projection module 7 and the display device 2, and reducing damage to the audio / video plug 13 and the power plug 12 caused by the wireless projection module 7.

[0030] To improve the practicality of the folding mechanism, the folding mechanism provided by this utility model includes two slides 3 located at the bottom of the bookshelf shelf 1, with the display device 2 positioned between the two slides 3. Correspondingly, the display device 2 is provided with support columns 8 and adjusting blocks 4 on both sides, respectively. The length of the adjusting block 4 is less than the length of the support column 8. The slides 3 are provided with guide grooves 5 for the support columns 8 and adjusting blocks 4 to move. One end of the guide groove 5 is connected to one end face of the slide 3, forming an inlet / outlet for the adjusting block 4 to move out. The two ends of the guide groove 5 can limit the maximum movement distance of the support column 8, and the display device 2 can rotate around the support center of the support column 8 in the guide groove 5 at a certain angle to achieve the functions of folding and retracting. When the display device 2 is in the unfolded state, the adjusting block 4 and the support column 8 are located on the inner and outer surfaces of the slide 3, providing a certain clamping effect. When the device is folded, the adjusting block 4 can slide from the inlet / outlet position into the guide groove 5, thereby making the display device 2 horizontal, i.e., entering the folded state.

[0031] Furthermore, when the support column 8 moves to the front end of the guide groove 5, the adjusting block 4 slides out of the guide groove 5 accordingly. At this time, the display device 2 can rotate around the support column 8, thereby changing the tilt angle of the display device 2. At the same time, the adjusting block 4 abuts against the outer side of the slide 3 and provides a force to maintain the tilt angle of the display device 2. In order to improve the contact effect between the adjusting block 4 and the slide, the adjusting block 4 provided by this utility model has a D-shaped structure and a protrusion 10 is provided on the side of the adjusting block 4 that abuts against the outer wall of the slide 3. The slide 3 is provided with a groove that cooperates with the protrusion 10. The protrusion 10 can be set as one, two, three or more, to increase its friction with the slide 3. The cooperation between the protrusion 10 and the groove can effectively improve the support cooperation effect between the slide and the adjusting block 4, thereby improving the practicality of the display device 2 in actual scenarios.

[0032] To improve the stability of the display device 2 in the folded state, the slide rail 3 provided by this utility model is also provided with a ball-head plunger 6, and the slide rail 3 is provided with a screw hole 9 for use with the ball-head plunger 6. When the display device 2 is in the folded state, one end of the ball-head plunger 6 extends to the bottom of the display device 2 and provides support force to stabilize the display device 2.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
