[0002] Electric doors are various doors driven by motors. Electric doors play a decisive role in our daily lives. They are safe, beautiful, convenient and easy to use, greatly improving our quality of life. Current electric doors are usually powered by a drive device, which is then driven by chains, gears, belts and other transmission parts to open or close the electric doors.

[0003] The existing electric door drive device is composed of a reduction motor, a driving gear, a driven gear and other parts. Each component is installed in a control box. Generally, there is a lack of space division for the control box, which is not conducive to maintenance and has a complex structure. The existing electric door drive device generally lacks a protective device. When the motor stops running, the door body will continue to move a short distance due to the inertia of the door body, which may cause the side wall of the door body to collide and damage the door body. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art, and provides an electric door. The switch of the door body can be regulated by a control mechanism. The structure is simple and easy to maintain. When the door needs to be opened or closed, the motor is started to drive the driving shaft to rotate, and then the first bevel gear and the second bevel gear are meshed and driven to rotate the first rotating shaft, and then the third bevel gear and the fourth bevel gear are meshed and driven to rotate the second rotating shaft, and then the spur gear and the rack are meshed and driven, so that the door body moves along the frame. The first cavity and the second cavity are used to provide a transmission space for the bevel gear set and separate the various components for easy maintenance. The convex ring can ensure the stability of the first rotating shaft and the second rotating shaft during rotation, and avoid affecting the meshing transmission of the gear set; the protective mechanism can protect the door body. When the door body moves to the side and stops, the side surface of the door body will be squeezed by the protective mechanism to compress the spring, which not only eliminates the inertia of the door body when moving, but also avoids the wear caused by the contact between the door body and the frame. The elastic pad can further improve the protective effect and has good practicality.
