Generally, in order to ensure that the positioning block 227 is attached to each of the door units 221, the mating end surface of the positioning block 227 is provided with a mating groove 2272 corresponding to the arc surface and a straight portion 2273 corresponding to the connecting piece 223 disposed between the mating grooves 2272, and when the positioning block 227 is attached to the inner surface of the door partition, the mating groove 2272 is attached to the arc surface, and the straight portion 2273 is attached to the connecting piece 223. The matching groove 2272 ensures that the relative positions of the arc surfaces are stable, that is, the intervals between the adjacent box door units 221 are fixed; the straight portion 2273 ensures that the connection member 223 at the connection between the adjacent door units 221 is in a straight state.
As shown in fig. 7, fig. 7 is a structural view of the positioning device; the control part 228 may be provided with a linkage mechanism 229, and the positioning block 227 may perform a curved motion in the positioning process through the linkage mechanism 229, so as to perform a certain position correction function on the door unit 221 in the positioning process; preferably, the linkage 229 comprises a push rod 2291 and a plurality of links 2292; the push rod 2291 is fixedly connected with the control part 228; one end of the connecting rod 2292 is connected with the positioning block 227 through a first rotating shaft 2293, the other end of the connecting rod 2292 is connected with the push rod 2291 through a second rotating shaft 2294, a long hole is further formed in the connecting rod 2292, a fixed shaft 2295 is arranged in the long hole, and the fixed shaft 2295 is fixedly arranged.
When the control part 228 drives the push rod 2291 to do linear motion, the connecting rod 2292 drives the push rod 2291 to rotate around the fixed shaft 2295 and simultaneously the fixed shaft 2295 moves in the long hole, so that the connecting rod 2292 and the end part connected with the positioning block 227 do curvilinear motion, and the curvilinear motion of the positioning block 227 is realized.
Specifically, as shown in fig. 8, fig. 8 is a motion track diagram of the first rotation shaft; when the positioning device releases the positioning and locking of the door unit 221, the control unit 228 drives the push rod 2291 to move horizontally to the right, and the positioning block 227 moves horizontally in a curved manner in a vertical direction after moving to the right, so that the positioning block 227 in a positioning state is used as a vertical auxiliary line perpendicular to the moving direction of the push rod 2291, and an end point of one of the connecting rods 2292 on the positioning block 227 is used as a reference point to simulate the moving track of the positioning block 227.

And similarly, the positioning block 227 tends to move in a curve manner during the positioning process. By the start-upThe swing between the initial position and the return position and under the elastic action of the contact layer 2271, the positioning block 227 corrects the individual box door 221, so as to ensure that the individual box door 221 is accurate in position.
Since the magnitude of the rightward movement of the positioning block 227 is generally small, the movement locus of the end point from the start position and the return position can be approximately regarded as the vertical movement along the vertical auxiliary line under the elastic action of the contact layer 2271; the distance between the initial position and the return position is set to be consistent with the depth dimension of the matching groove 2272 on the positioning block 227, so that the matching groove 2272 is prevented from interfering with the arc surface of the door unit 221 when the positioning block 227 moves further to the left side of the vertical auxiliary line, and the positioning block 227 moves smoothly.
In order to ensure that the positioning block 227 can perform a curved motion, a calculation formula of the distance L between the axis of the first rotating shaft 2293 and the axis of the second rotating shaft 2294 is as follows:
wherein h is the depth of the matching groove; m is the horizontal distance between the axle center of the second rotating shaft and the axle center of the fixed shaft, which are arranged on the same connecting rod in the locking state of the positioning block; n is the vertical distance between the axle center of the second rotating shaft and the axle center of the fixed shaft, which are arranged on the same connecting rod in the locking state of the positioning block.
Under the calculation formula of the distance L, the specific structure of the positioning component may be set through the corresponding surface structure of the box door unit 221, and when the arc surface radian of the box door unit 221 is larger, the depth of the mating groove 2272 is deeper, the distance L is longer.
Further, the calculation formula of the contact layer thickness s is as follows;
wherein h is the depth of the matching groove; m is the horizontal distance between the axle center of the second rotating shaft and the axle center of the fixed shaft, which are arranged on the same connecting rod in the locking state of the positioning block; n is the horizontal distance between the axle center of the second rotating shaft and the axle center of the fixed shaft, which are arranged on the same connecting rod in the locking state of the positioning block; alpha is a deformation parameter, and is generally 0.2 to 0.15.
In order to ensure that the swing between the initial position and the return position is within the elastic deformation range of the contact layer 2271, the specific thickness dimension of the contact layer 2271 can be further determined by determining the depth of the matching groove 2272, the horizontal distance and the vertical distance, so as to facilitate the structural design of the positioning component; thereby providing a suitable positioning assembly structure to ensure the positioning sealing effect of the positioning block 227 on the box door individual 221.
Preferably, the positioning blocks 227 are disposed on the rail portions 222 disposed on the upper and lower frames of the storage compartment 2, and the positioning blocks 227 are attached to the rail portions 222, so that when the positioning blocks 227 are in a positioning state, the positioning blocks 227 simultaneously realize a sealing effect on the connection positions between the rail portions 222 and the door units 221.
