In the closed state of the door body, the first pin shaft 7 is located at the right end of the first waist-shaped slot 401. With this structure, the setting of the first waist-shaped slot 401 enables the connecting seat 3 to have a certain movement space; when the door body is opened outward, the hinge arm 2 drives the connecting seat 3 to move, and the linkage arm 4 does not interfere with the movement of the connecting seat 3, making the manual door opening smooth.

[0035] Refer to Figure 5 and Figure 7 , when manually opening the door, manually open the door body outward, the door body drives the hinge arm 2 to rotate outward, the hinge arm 2 drives the connecting seat 3 to move, the connecting seat 3 drives the first pin shaft 7 to move, and the first pin shaft 7 moves from the right end of the first waist-shaped slot 401 to its left end; at the same time, the locking tongue 201 presses the movable locking pin 6 to retract it, and the movable locking pin 6 disengages from the locking tongue 201.

[0036] In some embodiments, such as Figure 1 and Figures 4 to 6As shown, a second waist-shaped slot 101 for the movable locking pin 6 to move is provided on the housing 1, and the movable locking pin 6 is placed in the second waist-shaped slot 101. A roller 601 is installed on the movable locking pin 6, and the roller 601 can be in rolling contact with the locking tongue 201. With this structure, the setting of the roller 601 can reduce friction, making it easier to open and close the door, and also extending the service life; the setting of the second waist-shaped slot 101 allows the movable locking pin 6 to have a certain movement space, facilitating automatic unlocking when opening the door and automatic locking when closing the door.

[0040] Refer to Figure 5, when the door is opened automatically, the driving motor 12 rotates, and the driving motor 12 drives the motor swing arm 5 to rotate clockwise (at this time, the first pin shaft 7 is placed at the right end of the first waist-shaped groove 401). The motor swing arm 5 drives the linkage arm 4 to move. The linkage arm 4 pushes the connecting seat 3 to move outward through the first pin shaft 7, so that the hinge arm 2 rotates outward to open, and the lock tongue 201 disengages from the movable lock pin 6, and the door body opens. When the door is closed automatically, the driving motor 12 rotates in the reverse direction. The driving motor 12 drives the motor swing arm 5 to rotate counterclockwise (at this time, the first pin shaft 7 is placed at the right end of the first waist-shaped groove 401). The motor swing arm 5 drives the linkage arm 4 to move so that the first pin shaft 7 is placed at the left end of the first waist-shaped groove 401. At this time, the linkage arm 4 can drive the connecting seat 3 to move inward through the first pin shaft 7. The connecting seat 3 drives the hinge arm 2 to rotate inward to close, and the lock tongue 201 is clamped with the movable lock pin 6, and the door body closes. After the door body is closed, in order to ensure that the door body can be manually opened next time, the driving motor 12 needs to drive the linkage arm 4 to reset, so that the first pin shaft 7 is placed at the right end of the first waist-shaped groove 401 again. This structure can perform manual and automatic door opening, and is convenient to use.
