Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This embodiment provides a plate-shaped body driving mechanism for driving the plate-shaped body 100, such as... Figures 2-4 As shown, the plate-shaped body driving mechanism includes a support base 1, a driving assembly 2, a transmission assembly, a first push rod 3, a second push rod 4, and two connecting seats 5 spaced apart along a first direction on the mounting surface of the plate-shaped body 100. The support base 1 is used to connect with an external bearing component. The driving assembly 2 is mounted on the support base 1 and can reciprocate relative to the support base 1 along the first direction. The transmission assembly is connected to the power output of the driving assembly 2 and is also connected to both the first push rod 3 and the second push rod 4. Each connecting seat 5 corresponds to one of the push rods. The end of each push rod away from the transmission assembly is slidably connected to the corresponding connecting seat 5 and can rotate relative to the corresponding connecting seat 5.

[0041] When the drive assembly 2 is in the first working state, the first push rod 3 can push the plate-shaped body 100 to rotate around the connection point between the second push rod 4 and the plate-shaped body 100 under the action of the drive assembly 2 and the transmission assembly; when the drive assembly 2 is in the second working state, the second push rod 4 can push the plate-shaped body 100 to rotate around the connection point between the first push rod 3 and the plate-shaped body 100 under the action of the drive assembly 2 and the transmission assembly.

[0042] The plate body driving mechanism provided in the embodiment is used for driving the plate body 100, wherein the support base 1 is used for being connected with an external bearing part, the driving assembly 2 is arranged on the support base 1 and can reciprocate along a first direction relative to the support base 1, the first push rod 3 and the second push rod 4 are both in driving connection with the transmission assembly, and the ends away from the transmission assembly are respectively in sliding connection with the corresponding connecting seats 5 and can rotate relative to the corresponding connecting seats 5. Meanwhile, when the driving assembly 2 is in a first working state, the first push rod 3 can push the plate body 100 to overturn with the connecting point between the second push rod 4 and the plate body 100 as a fulcrum under the action of the driving assembly 2 and the transmission assembly; when the driving assembly 2 is in a second working state, the second push rod 4 can push the plate body 100 to overturn with the connecting point between the first push rod 3 and the plate body 100 as a fulcrum under the action of the driving assembly 2 and the transmission assembly. It can be seen that the plate body driving mechanism provided in the embodiment can make the plate body 100 avoid interference in the first direction in the overturning process through the movement of the driving assembly 2 along the first direction relative to the support base 1, so as to avoid the problem of interference between the plate body 100 and the obstacle in the overturning process.

[0043] As shown in Figure 5 When the plate body 100 is a vehicle-mounted central control screen, the movement of the driving assembly 2 along the first direction relative to the support base 1 can make the vehicle-mounted central control screen move away from the direction of the hand operation space 200, so as to make the vehicle-mounted central control screen avoid the hand operation space 200 in the overturning process.
