[0002] Tablet computers, also known as portable computers, are small, portable personal computers that use a touchscreen as their basic input device. The touchscreen (also called a digitizer) allows users to perform tasks using a stylus or digital pen instead of a traditional keyboard or mouse. Users can input through built-in handwriting recognition, an on-screen soft keyboard, voice recognition, or a physical keyboard (if the model is equipped with one). Educational tablets primarily aim to help children improve their skills and academic performance, providing them with a complete learning method. Through using the device, children can quickly understand textbook knowledge, improve their overall knowledge, and enhance their comprehensive abilities. For ease of use, educational tablets are often placed on stands to adjust their position.

[0003] Most existing tablet stands only adjust the tilt angle of the tablet, but cannot adjust the height of the tablet when adjusting the tilt angle. This limits the use of the stand, and the wobbling of the stand can also affect the stability of the tablet. Utility Model Content

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] like Figures 1 to 3 As shown, an embodiment of this utility model provides a support device for an educational tablet. The device includes a support base 1, a lifting assembly 2, and an adjusting assembly 3. The lifting assembly 2 includes a positive and negative lead screw 21, with a drive gear 22 fixedly connected to the end face of the positive and negative lead screw 21. A rack plate 23 meshes with the outer wall surface of the drive gear 22. A lead screw slider 24 is installed on the outer wall surface of the positive and negative lead screw 21. A first fixing block 25 is fixedly connected to the end face of the lead screw slider 24. A lifting plate 26 is rotatably connected to the outer wall surface of the first fixing block 25 via a first fixing rod. The outer wall of 26 is rotatably connected to a second fixing block 27 via a second fixing rod. The adjusting assembly 3 includes an adjusting seat 31, an adjusting plate 32 is rotatably connected to the inner wall of the adjusting seat 31, a support block 33 is fixedly connected to the end face of the adjusting plate 32, a fixing plate 34 is rotatably connected to the outer wall of the support block 33, a limit spring 35 is fixedly connected to the inner wall of the adjusting plate 32, a limit plate 36 is fixedly connected to the end face of the limit spring 35, a locking plate 37 is rotatably connected to the outer wall of the limit plate 36, and a positioning plate 38 is rotatably connected to the free end of the adjusting plate 32.

[0017] This utility model provides a support device for an educational tablet. The lifting component 2 allows for easy adjustment of the tablet's height during support, and is simple to operate. Adjustment via a mechanically driven force increases the stability of the support, reducing the probability of the tablet tipping over due to collisions. The adjusting component 3 allows for adjustment of the tablet's tilt angle, facilitating child use and learning. It also provides pressure restraint for the tablet, further increasing stability and reducing the likelihood of it tipping over.

[0018] In this embodiment of the invention, during use, the sealing cover 14 is opened, and the rack plate 23 is moved. Due to the movement of the rack plate 23, the drive gear 22 is driven, which rotates the positive and negative lead screw 21. This causes the lead screw slider 24 to convert the rotational motion of the positive and negative lead screw 21 into linear motion, driving the lifting plate 26 to move and adjusting the height of the adjusting seat 31. Then, the adjusting plate 32 is rotated, and the fixed plate 34 is supported by the fixed plate 34 and the limiting hole 302 after the angle is adjusted. Then, the locking plate 37 and the positioning plate 38 are rotated ninety degrees, and the educational tablet is placed between the locking plate 37 and the positioning plate 38. Due to the force of the limiting spring 35, the locking plate 37 presses the educational tablet, making its adjustment support stable.

[0019] like Figure 3 As shown, as a further embodiment of the present utility model, the inner wall surface of the support base 1 is also provided with a support groove 11, and the outer wall surface of the rack plate 23 is slidably connected to the support base 1 through the support groove 11. In this embodiment, the rack plate 23 is configured so that the drive gear 22 is rotated by the force of the rack plate 23, thereby driving the positive and negative lead screws 21, so that the lead screw slider 24 can move, thereby adjusting the height of the adjusting component 3 by the force of the lifting plate 26.

[0020] like Figure 2 As shown, as a further embodiment of the present utility model, a rubber pad 13 is fixedly connected to the end face of the support base 1. The rubber pad 13 is elastic, and a sealing cap 14 is snapped onto the outer wall surface of the support base 1. In this embodiment, the elastic rubber pad 13 can increase the frictional resistance in contact with the end face, making it less likely to tilt or tip over, thus increasing the stability of the educational tablet support.

[0021] like Figure 2 and Figure 3 As shown, as a further embodiment of the present invention, a support rod 12 is slidably connected to the inner wall surface of the support base 1, and the end face of the support rod 12 is fixedly connected to the adjustment base 31. In this embodiment, due to the limiting force of the support rod 12, when the height of the adjustment component 3 is adjusted by the lifting plate 26, the four support rods 12 are in contact with the support base 1. While supporting the adjustment component 3, it can also prevent the adjustment component 3 from tilting outward, thereby further increasing the stability of the educational tablet support.

[0022] like Figure 3As shown, in a further embodiment of the present invention, the outer wall of the positive and negative lead screw 21 is rotatably connected to the support base 1, and a limit ring 28 is also fixedly connected to the outer wall of the positive and negative lead screw 21. In this embodiment, the limiting ring 28 is used to limit the movement distance of the lead screw slider 24, thereby limiting the rotation angle of the lifting plate 26, which in turn limits the lifting height of the adjustment component 3, thus limiting the adjustable height of the educational tablet.

[0023] like Figure 1 and Figure 2 As shown, in a further embodiment of the present utility model, the end face of the adjusting seat 31 is fixedly connected to the second fixing block 27, and the inner wall surface of the adjusting seat 31 is also provided with a limiting hole 302. The outer wall surface of the fixing plate 34 is inserted into the adjusting seat 31 through the limiting hole 302. The free end of the adjusting seat 31 is rotatably connected to the limiting block 301, and the outer wall surface of the limiting plate 36 is slidably connected to the adjusting plate 32. In this embodiment, the fixed plate 34 and the adjustment hole limiting hole 302 are used to facilitate the support of the adjustment plate 32 after rotation, so that the tilt angle of the adjustment plate 32 can be adjusted to support the educational tablet at different angles, making it easier for children to use. Moreover, after the locking plate 37 and the positioning plate 38 rotate, they can lock the educational tablet together, and the locking plate 37 will be subjected to the pulling force of the limiting spring 35, which can fit the educational tablet together and limit its position, increasing the stability of the educational tablet during use.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
