Furthermore, the contact surface between the first support plate 12 and the panel of the tablet computer is provided with an anti-slip leather layer.

It should be noted that by providing an anti-slip leather layer on the contact surface between the first support plate 12 and the panel of the tablet computer, one side of the tablet computer can be placed on the first support plate 12 when the tablet computer needs to be placed horizontally. , through the anti-slip leather layer on the first support plate 12, the friction between the tablet computer and the first support plate 12 is effectively improved. Therefore, through the cooperation of the tablet computer and the anti-skid leather layer, the friction between the tablet computer, the second support plate 22 and part of the first support When the plate 12 forms a triangle, the second support plate 22 supports the tablet computer and adjusts the position of the tablet computer on the first support plate 12 to realize multi-angle adjustment of the tablet computer.

The magnets in the first magnet group 111, the second magnet group 211, the third magnet group 223, the fourth magnet group 112, the fifth magnet group 213 and the sixth magnet group 31 provided above can be multiple magnets with the same magnetic poles. It can also be magnets with different magnetic poles, and multiple magnets in the first magnet group 111, the second magnet group 211, the third magnet group 223, the fourth magnet group 112, the fifth magnet group 213 and the sixth magnet group 31 are arranged. into magnets with different magnetic poles, and arranging N-pole magnets and S-pole magnets adjacent to each other (as shown in Figure 1), which can effectively reduce the repulsive force caused by magnets of the same pole when installing the magnets, and thus more magnets can be installed , and then can provide the maximum adsorption force when fixed to the bottom case of the tablet computer, that is, improving the fixing strength of the corresponding components.

It should also be noted that magnets are built into the bottom case of existing tablet computers, and the magnets are located on the four sides of the bottom case. Correspondingly, the first magnet group 111 in the present invention is located on the second side of the first fixing plate 11 . side, the second magnet set 211 is disposed on the second side of the second fixed plate, and the third magnet set 223 is disposed on the first side of the second support plate 22 (the first side and/or the second polygonal plate 221 The first right-angled side of the two right-angled triangles 222).

The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be practiced in other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
