[0034] like Figures 1 to 3 As shown, the embodiment of the present application provides a keyboard screen flipping device, comprising:

[0035] The installation assembly 100 includes a left support seat 110, a right support seat 120 and a rear sealing seat 130. The left support seat 110, the right support seat 120 and the rear sealing seat 130 are detachably connected. The left support seat 110 and the right support seat 120 are spaced apart and distributed on both sides of the rear sealing seat 130. The left support seat 110, the right support seat 120 and the rear sealing seat 130 form a receiving space 140 together.

[0036] The flip drive assembly 200 includes a side seat 210, a driving source, a control panel 230, a transmission mechanism 240 and a rotating shaft 250. The side seat 210 is spaced apart from the left support seat 110. The driving source and the control panel 230 are both mounted on the side seat 210. The control panel 230 is electrically connected to the driving source. A control switch is integrated on the control panel 230. The rotating shaft 250 is rotatably disposed on the left support seat 110 and the right support seat 120. One end of the rotating shaft 250 close to the left support seat 110 is connected to the driving source through the transmission mechanism 240.

[0037] The display module 300 is mounted on the rotating shaft 250 and is located in the accommodating space 140 .

[0038] In the installation assembly 100, the left support seat 110, the right support seat 120 and the rear sealing seat 130 are detachably connected, and the flip drive assembly 200 and the display module 300 can be easily installed and removed. In addition, the left support seat 110, the right support seat 120 and the rear sealing seat 130 together form a receiving space 140, so that the display module 300 can be placed therein, which can save space on the one hand and protect the display module 300 from external damage on the other hand.

[0039] More specifically, a first slot and a second slot are provided on two opposite surfaces of the rear sealing seat 130, the left support seat 110 has a first plug block inserted into the first slot, and the right support seat 120 has a second plug block inserted into the second slot. Subsequently, the first plug block and the second plug block are locked by screwing screws from the bottom surface of the rear sealing seat 130 to improve the connection stability between the left support seat 110, the right support seat 120 and the rear sealing seat 130.

[0040] In addition, a first receiving groove is provided on the left support seat 110, and a second receiving groove is provided on the right support seat 120. Bearings are provided in the first receiving groove and the second receiving groove. The rotating shaft 250 is passed through the bearings of the first receiving groove and the second receiving groove to realize the rotation of the rotating shaft 250, so that the display module 300 can be flipped around the rotating shaft 250.

[0041] In the flip driving assembly 200 , the driving source is a common driving mechanism, and in some embodiments, the driving source is a motor. In addition, the transmission mechanism 240 is a gear transmission mechanism 240 .

[0042] For example, by pressing the control switch, the driving source is started, the driving source works, and the transmission mechanism 240 drives the rotating shaft 250 to rotate, so that the display module 300 is turned around the rotating shaft 250 .

[0043] like Figures 1 to 3As shown, in some embodiments, the display module 300 has a recess 310, and the recess 310 has a first abutting surface 311 and a second abutting surface 312 connected to each other; the rear sealing seat 130 is provided with a rotation-stopping mechanism 131, and the rotation-stopping mechanism 131 is configured so that when the display module 300 is fully turned over, the first abutting surface 311 abuts against the rotation-stopping mechanism 131. Specifically, the first abutting surface 311 cooperates with the rotation-stopping mechanism 131 to ensure that the display module 300 can stably stay at a designated position during the flipping process, avoid accidental flipping, and make the display module 300 more stable after flipping without shaking.

[0044] The display module 300 also has a cover surface and a display surface connected to each other, and an angle is formed between the cover surface and the display surface. When the display module 300 is closed, the cover surface is generally arranged upward, so that the display surface is stored inside the keyboard to protect the display surface of the display module 300. When the display module 300 is fully opened, the display surface will be generally inclined to the keyboard surface and face the user, which is convenient for the user to watch.

[0045] like Figures 1 to 3 As shown, in some embodiments, the anti-rotation mechanism 131 includes an anti-rotation block 1311, and the anti-rotation block 1311 has two anti-rotation blocks 1311 and is spaced apart on the rear sealing seat 130. The anti-rotation block 1311 is configured so that when the display module 300 is fully opened, the first abutting surface 311 abuts against the anti-rotation block 1311. One anti-rotation block 1311 is provided at one end of the rear sealing seat 130 close to the left support seat 110, and the other anti-rotation block 1311 is provided at one end of the rear sealing seat 130 close to the right support seat 120. The anti-rotation blocks 1311 are evenly spaced apart, thereby providing a uniform supporting force and a balancing force to the display module 300, so that the display module 300 is more stable when opened.

[0046] like Figures 1 to 3 As shown, in some embodiments, a matching groove 313 is formed on the first abutting surface 311 and the second abutting surface 312; the rear sealing seat 130 has a first electronic switch 132 and a second electronic switch 133 both electrically connected to the control board 230; when the display module 300 is closed, the sensing end of the first electronic switch 132 abuts against the second abutting surface 312, and the second electronic switch 133 is arranged corresponding to the matching groove 313; when the display module 300 is fully opened, the second electronic switch 133 abuts against the edge of the matching groove 313. Specifically, by arranging the first electronic switch 132 and the second electronic switch 133 to cooperate with the display module 300, the driving source is controlled to stop working, so as to realize the anti-rotation control of the display module 300.

[0047] The above are only preferred embodiments of the present application, and do not constitute any formal limitation on the present application. Any technician familiar with the art can use the above disclosed methods and technical contents to make many possible changes and modifications to the technical solution of the present application without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present application without departing from the content of the technical solution of the present application should be included in the protection scope of the present application.
