When the door is opened, the motor is started, and the first transmission member 151 drives the second transmission member 132 to move, so that the door main body 12 can move along the slide rail 111 toward the side wall 23 of the box body 20. Until the door body 12 moves to the side wall 23 of the cabinet 20 completely, the door 10 is in a completely opened state, and the motor stops operating.

When the door is closed, the motor works in the reverse direction, and the first transmission member 151 drives the second transmission member 132 to move in the reverse direction, so that the door main body 12 can move along the slide rail 111 toward the front side 22 of the box body 20. Until the door body 12 is completely moved to the front side 22 of the cabinet 20, the door body 10 is in a completely closed state, and the motor stops operating.

In this embodiment, the first transmission member 151 may include a gear. The second transmission member 132 may comprise a chain, and the first transmission member 151 and the second transmission member 132 are engaged with each other.

In addition, the second transmission member 132 may further include a rack gear engaged with the first transmission member 151. Of course, the first transmission member 151 and the second transmission member 132 may also include transmission mechanisms in other transmission forms, for example, friction transmission, belt transmission, etc., and the present invention is not limited thereto, as long as the automatic door opening function of the door 10 can be realized.

In some embodiments, the height of the second transmission pieces 132 of the respective door units 13 in the longitudinal direction of the door units 13 is the same, and the dimension of each second transmission piece 132 in the transverse direction of the door unit 13 is the same as the dimension in the transverse direction of the door unit 13.

In one embodiment, as shown in fig. 3 and 4, the second transmission members 132 of the door units 13 of one door main body 12 can be separated from each other, so that when the door main body 12 slides through the corner formed between the front side 22 and the side wall 23 of the cabinet 20, the adjacent two door units 13 at the corner can be completely separated during the door opening or closing process, and can slide down the corner under the pushing of the first transmission member 151, respectively, thereby improving the smoothness during sliding. In the present embodiment, the plurality of second transmission members 132 are disposed at the same height in the longitudinal direction of the door unit 13, so that the plurality of second transmission members 132 separated from each other can be all located on the conveying path, ensuring the transmission efficiency between the plurality of second transmission members 132 and the first transmission member 151.

In another embodiment, as shown in fig. 6, the second transmission members 132 of the door units 13 of one door main body 12 may be connected to form a complete conveyor belt, so that at least one side of the box 20 is abutted between every two adjacent door units 13 of the door main bodies 12 in the transverse direction. When the door main body 12 slides across the corner formed between the front side 22 and the side wall 23 of the box body 20, in the door opening or closing process, two adjacent door units 13 at the corner abut against one side of the box body 20 and separate from one side of the box body 20, so that the sliding smoothness is ensured, and meanwhile, the structural stability of the door main body 12 is also ensured.

In some embodiments, the door body 10 may further include a sealing portion (not shown) disposed at a side of each door main body 12 facing the cabinet 20. The seal portion is made of a flexible sheet material, and a plurality of door units 13 of each door main body 12 are compactly arranged and fixedly disposed on the seal portion in the lateral direction. On this basis, the sum of the dimensions of the plurality of door units 13 of each door main body 12 in the transverse direction is the same as the transverse dimension of the door main body 12, and the dimension of the sealing part in the transverse direction of the door main body 12 is not smaller than the sum of the dimensions of all the door units 13 of the door main body 12 except for the two door units 13 on the left and right sides in the transverse direction, so that the plurality of door units 13 of each door main body 12 are connected into a whole, and the sealing efficiency when the door body 10 is in a fully closed state is improved.

In some embodiments, as shown in fig. 6, the locking device of the door body 10 may further include an elastic member 16. The elastic member 16 is in the form of a sheet or a strip, and covers the side of all the door units 13 of each door main body 12 facing away from the cabinet 20. When the door main body 12 slides over the corner formed between the front side 22 and the side wall 23 of the cabinet 20, during the door opening or closing process, the two adjacent door units 13 at the corner at least provided with the side away from the cabinet 20 can be completely separated, and the elastic piece 16 is spread, stressed and expanded, and stores elastic potential energy. After the two adjacent door units 13 slide through the corner, the elastic member 16 releases the elastic potential energy to pull the two adjacent door units 13 tightly, so that the two adjacent door units are arranged tightly again, and the structural stability of the door main body 12 is further ensured.
