[0053] A door hinge 5, one end is connected to the door body 2, and the other end is hinged to the other end of the electric push rod 4. The door hinge 5 is arranged in a long strip shape and is made of a metal material. In this embodiment, a rotating groove 53 is provided on the door hinge 5, and the door hinge 5 rotates with the rotating groove 53 as a fulcrum.

[0054] Specifically, in order to realize the connection between the electromagnet assembly 3 and the electric push rod assembly, in this embodiment, the electromagnet assembly 3 is provided with a movable rod 31. The movable rod 31 is adapted to perform an extending action when the electromagnet assembly 3 is energized. At the same time, the movable rod 31 of the electromagnet assembly 3 acts on the part where the electric push rod 4 is hinged to the door hinge 5, such as Figure 4 As shown in the figure, the movable rod 31 acts at the hinge point position between the second push rod 42 and the door hinge 5.

[0055] In this embodiment, the installation position of the electromagnet assembly 3 is not overly limited. It can be directly installed on the side plate 12. At this time, the electromagnet assembly 3 can be installed by means of snap fasteners or welding. As a preferred implementation method, the electromagnet assembly 3 is connected to the electric push rod 4, so as to ensure that the movable rod 31 of the electromagnet assembly 3 is closer to the hinge point position, thereby improving the connection stability between the movable rod 31 and the hinge point.

[0056] At this time, in order to fix the electromagnet assembly 3, a first fixing block 6 is provided on the electric push rod 4, and a second fixing block 7 is provided on the electromagnet assembly 3. Connecting holes 521 are provided at the corresponding parts of the first fixing block 6 and the second fixing block 7. Connecting parts such as screws pass through the connecting holes 521 to connect the first fixing block 6 and the second fixing block 7 into one body. Specifically as Figure 4 Shown in the right side position, when the connection is completed, the door hinge 5 itself will be at the lower position where the second fixing block 7 is provided.

[0057] In this embodiment, as Figure 7As shown, at least one movable part connection hole 9 is provided at a position corresponding to the door hinge 5 and the door body 2. A movable part is arranged inside the movable part connection hole 9. By providing the movable part connection hole 9 and the movable part, when the electromagnet assembly 3 fails and causes the electric push rod assembly to fail to separate normally, the movable part can be removed from the movable part connection hole 9, so as to realize the disassembly operation between the door body 2 and the door hinge 5, thereby ensuring that the door body 2 can be disassembled from the main body 1.

[0058] Specifically, the movable part can be structures such as screws and pins. As a preferred embodiment, the movable part is a lifting eye screw 10, and the lifting eye screw 10 itself has an annular structure for pulling, which is convenient for users to operate.

[0060] Through the combination of the fixing part 12 and the movable part, since the fixing part 12 is arranged below the movable part, when the electromagnet assembly 3 is damaged, the fixing part 12 can be retained and the movable part can be removed, so that the door body 2 can be opened by only rotating the door body 2 by a certain angle without disassembling the door body 2.

[0061] In this embodiment, in order to cooperate with the movement of the electric push rod 4 itself, a current monitoring module is further included. The current monitoring module is connected to the electric push rod 4 and the controller at the same time. When the second push rod 42 extends to the maximum distance relative to the first push rod 41, the second push rod 42 itself will not be able to move relative to the first push rod 41. At this time, the current inside the electric push rod 4 will increase. After the current monitoring module monitors the increase in the current inside the electric push rod 4, it sends a signal to the controller, and the controller will further control the electric push rod 4 to stop being powered on, so as to avoid the electric push rod 4 being burned out after overheating.
