DETAILED DESCRIPTION

[0026] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.

[0030] Reference Figure 8 The bracket 1 includes a main bracket 101, a fixing bracket mounting block 102 symmetrically arranged on the main bracket 101, a crossbeam 103 arranged between the fixing bracket mounting blocks 102, and reinforcing ribs 104 arranged on both sides of the main bracket 101.

[0031] Reference Fig.10 The first driving link 5 is provided with a connecting shaft hole 501 on the fixing frame side for connecting to the fixing frame 2, a connecting shaft hole 502 on the folding shell side for connecting to the folding shell 4, and a connecting shaft hole 503 on the second driving link side for connecting to the second driving link 6.

[0032] The following will refer to Figures 1 to 10 The working principle of the present invention is described.

[0033] An electric folding and telescopic accompanying mechanism of the present invention adopts a motor to drive a driving arm 7 to perform linear reciprocating motion. When the driving arm 7 moves forward, it drives the second driving link 6 to move forward, and then drives the first driving link 5 to move forward. The limiting protrusion 301 on the swing arm 3 disengages from the limiting hole 401, and the two folding shells 4 perform a closing movement. When the driving arm 7 moves forward to a set position, the second driving link 6 and the first driving link 5 are locked, and the two folding shells 4 are in a closed state; on the contrary, when the driving arm 7 moves backward, it drives the second driving link 6 to move backward, and then drives the first driving link 5 to move backward. The limiting protrusion 301 on the swing arm 3 is stuck in the limiting hole 401, and the two folding shells 4 perform an opening movement. When the driving arm 7 moves backward to a set position, the spring 8 locks the two folding shells 4, and the two folding shells 4 are in an open state.

[0034] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
