DETAILED DESCRIPTION

[0019] The door and drawer of the conventional disinfection cabinet are fixed together and are pulled out on the guide rail. The opening door mode is straight pulling type. On the one hand, the upper door and the lower door cannot be automatically opened, and the degree of automation is low. On the other hand, after the drawer of the upper door or the lower door is pulled out, the space occupied is large, which is not convenient for the user to flexibly take the bowl.

[0020] Please refer to Figure 1 and Figure 2 In order to solve the problems that the upper door and the lower door of the disinfection cabinet cannot be automatically and synchronously opened and closed and the space occupied by the opening door is large, the present application provides a door body structure and a disinfection cabinet. The door body structure comprises a linear drive mechanism 100, a link assembly 200, a cabinet door assembly 300 and a cabinet body assembly 400. The link assembly 200 is respectively hinged to the output end of the linear drive mechanism 100, the cabinet door assembly 300 and the cabinet body assembly 400.

[0021] When the output end of the linear drive mechanism 100 drives the hinged point of itself and the link assembly 200 to move along the first direction (indicated by S in the figure), the link assembly 200 can drive the cabinet door assembly 300 to overturn relative to the cabinet body assembly 400 to open the opening of the cabinet body assembly 400.

[0022] When the output end of the linear driving mechanism 100 drives itself and the hinge point of the linkage assembly 200 to move along the reverse direction of the first direction, the linkage assembly 200 can drive the cabinet door assembly 300 to rotate relative to the cabinet body assembly 400 to close the opening of the cabinet body assembly 400.

[0023] In this way, on the one hand, the opening and closing of the cabinet door assembly 300 is realized by the linear driving mechanism 100, which greatly improves the automation degree of the door structure and liberates manpower. On the other hand, the linear driving mechanism 100 drives the entire cabinet door assembly 300 to flip to realize the opening and closing of the cabinet door assembly 300 relative to the cabinet body assembly 400. In this way, only the cabinet door assembly 300 needs to be opened, and there is no need to pull out the drawer inside, which reduces the space occupied by the opening of the door structure and facilitates the user to take the bowl.

[0024] In an embodiment, the number of linear driving mechanisms 100 is multiple, and the number of linkage assemblies 200 is also multiple. They are arranged in correspondence. When the number of both is two, the linear driving mechanisms 100 are distributed on the left and right sides of the sterilization cabinet, and similarly, the linkage assemblies 200 are distributed on the left and right sides of the sterilization cabinet to improve the force stability of the cabinet door assembly 300.

[0025] In an embodiment, as shown in Figure 1 and Figure 2 , the cabinet body assembly 400 is provided with a linear sliding groove 421 extending along the first direction, and the output end of the linear driving mechanism 100 can slide along the first direction with the linear sliding groove 421.

[0026] In this way, the output end of the linear driving mechanism 100 can be effectively limited, and the output end of the linear driving mechanism 100 is prevented from deviating to cause the cabinet door assembly 300 to be unable to be normally opened and closed.

[0027] However, it is not limited to this. In other embodiments, the output end of the linear driving mechanism 100 can also be limited by the structure of the linear driving mechanism 100 itself. For example, the output end of the linear driving mechanism 100 can be a telescopic rod structure.

[0028] Further, in an embodiment, as shown in Figure 1 and Figure 2 , the cabinet body assembly 400 includes a main cabinet body 410 and a sliding groove plate 420, the sliding groove plate 420 is installed on the main cabinet body 410, and the linear sliding groove 421 is arranged on the sliding groove plate 420.

[0029] Compared with the linear sliding groove 421 arranged directly on the side wall of the main cabinet body 410, in this way, the difficulty of processing and assembling of the linear sliding groove 421 is greatly reduced.

[0030] Further, in an embodiment, as shown in Figure 1 andFigure 2 As shown in FIG. 1, the linear driving mechanism 100 comprises a driving motor 110, a screw rod (not shown in the figure) and a first sliding block 120, the first sliding block 120 and the linear sliding groove 421 are slidingly fitted along the first direction, one end of the screw rod is connected to the rotating shaft of the driving motor 110, the other end is threadedly connected with the first sliding block 120, and the driving motor 110 can drive the screw rod to rotate to drive the first sliding block 120 to move linearly relative to the linear sliding groove 421.

[0031] In this way, the rotation of the rotating shaft of the driving motor 110 can be converted into the linear motion of the first sliding block 120 by the screw rod and the linear sliding groove 421, and the control precision of the driving motor 110 is high, which is conducive to improving the moving position of the cabinet door assembly 300 controlled by the linear driving mechanism 100.

[0032] In another embodiment, the linear driving mechanism 100 comprises a driving cylinder (not shown in the figure) and a second sliding block (not shown in the figure), the second sliding block is connected to the piston of the driving cylinder, and the driving cylinder can drive the second sliding block to slide along the first direction relative to the linear sliding groove 421 through the piston.

[0033] In this way, the structure of the linear driving mechanism 100 is simpler, which is conducive to the assembly of the linear driving mechanism 100 in the door body structure.

[0034] In an embodiment, as shown in FIG. 1, Figure 1 and Figure 2 As shown in FIG. 1, the linkage assembly 200 comprises a first linkage 210, a second linkage 220 and a third linkage 230, one end of the first linkage 210 is hingedly connected to the output end of the linear driving mechanism 100, the other end is hingedly connected to the cabinet door assembly 300, one end of the second linkage 220 is hingedly connected to the cabinet body assembly 400, the other end is hingedly connected to the third linkage 230, one end of the third linkage 230 away from the first linkage 210 is hingedly connected to the cabinet door assembly 300, and the first linkage 210 and the second linkage 220 are cross-connected at the intersection. Moreover, the distance M between the two hinged points of the first linkage 210 itself, the distance N between the two hinged points of the second linkage 220 itself, and the distance L between the two hinged points of the third linkage 230 itself satisfy M < N + L.

[0035] In this way, the linkage mechanism is cross-hinged, and the total length of the second linkage 220 and the third linkage 230 is greater than the total length of the first linkage 210, which is conducive to driving the cabinet door assembly 300 to flip away from the linear driving mechanism 100 to open the cabinet body assembly 400.

[0036] Specifically, when the output end of the linear driving mechanism 100 drives the hinged point of the first connecting rod 210 and the first slider 120 or the second slider to move towards the hinged point of the second connecting rod 220 and the cabinet assembly 400, the hinged point of the first connecting rod 210 and the cabinet door assembly 300 can move towards the linear driving mechanism 100, and the hinged point of the third connecting rod 230 and the cabinet door assembly 300 can move away from the linear driving mechanism 100, so as to make the cabinet door assembly 300 turn over and open the cabinet assembly 400.

[0037] Conversely, when the output end of the linear driving mechanism 100 drives the hinged point of the first connecting rod 210 and the first slider 120 or the second slider to move away from the hinged point of the second connecting rod 220 and the cabinet assembly 400, the hinged point of the first connecting rod 210 and the cabinet door assembly 300 can move away from the linear driving mechanism 100, and the hinged point of the third connecting rod 230 and the cabinet door assembly 300 can move towards the linear driving mechanism 100, so as to make the cabinet door assembly 300 turn back and close the cabinet assembly 400.

[0038] Further, in an embodiment, as shown in Figure 1 and Figure 2 , the hinged point of the second connecting rod 220 and the cabinet assembly 400 is located on the movement line of the output end of the linear driving mechanism 100.

[0039] That is, the hinged points of the first connecting rod 210 and the output end of the linear driving mechanism 100 and the hinged point of the second connecting rod 220 and the cabinet assembly 400 are distributed along the first direction.

[0040] In this way, the stability of the movement force of the connecting rod assembly 200 is improved.

[0041] However, the hinged point of the second connecting rod 220 and the cabinet assembly 400 can also be arranged towards the direction of the cabinet door assembly 300 or away from the direction of the cabinet door assembly 300 in other embodiments.

[0042] Further, in an embodiment, as shown in Figure 1 and Figure 2 , the cabinet door assembly 300 comprises a main door body 310 and a fixed support 320, and the connecting rod assembly 200 is connected to the main door body 310 through the fixed support 320 to drive the main door body 310 to open or close the cabinet assembly 400.

[0043] Specifically, the first connecting rod 210 is hinged to one end of the fixed support 320, the third connecting rod 230 is hinged to the other end of the fixed support 320, and the hinged point of the first connecting rod 210 and the fixed support 320 is away from the main door body 310 by a straight line distance B, the hinged point of the third connecting rod 230 and the fixed support 320 is away from the main door body 310 by a straight line distance C, and B > C is satisfied.

[0044] More specifically, as shown in Figure 1 and Figure 2 , the fixed support 320 is in the shape of a right triangle as a whole, the fixed support 320 comprises a first side 321, a second side 322 and a third side 323 connected end to end, the first side 321 and the second side 322 are right angle sides, and the third side 323 is a hypotenuse, the first side 321 is connected to the main door body 310, the third side 323 is hinged to the first connecting rod 210 at the connection with the second side 322, and the third side 323 is hinged to the third connecting rod 230 at the connection with the first side 321.

[0045] In this way, by arranging the fixed support 320, and the hinged point of the first connecting rod 210 and the fixed support 320 being away from the main door body 310 by a straight line distance B, the hinged point of the third connecting rod 230 and the fixed support 320 being away from the main door body 310 by a straight line distance C, and B > C being satisfied, that is, the hinged point of the first connecting rod 210 and the fixed support 320 is farther away from the main door body 310, it is more conducive to the overturning of the main door body 310.

[0046] Furthermore, in an embodiment, as shown in Figure 1 and Figure 2 , when the output end of the linear drive mechanism 100 drives the hinged point of the first connecting rod 210 to move to the maximum distance along the first direction, the maximum angle A of the cabinet door assembly 300 relative to the cabinet body assembly 400 is satisfied with 60° ≤ A ≤ 180°, and preferably A is equal to 90°.

[0047] In this way, the cabinet door assembly 300 can be opened to an appropriate angle, which is conducive to the taking of the bowl and reduces the space occupied by the cabinet door assembly 300.

[0048] Especially, when the cabinet door assembly 300 is opened to an angle of 90°, the cabinet door assembly 300 is arranged horizontally, at this time, the steel wire basket and the bowl and other articles can be placed on the cabinet door assembly 300, so that the entire area is fully utilized.

[0049] Furthermore, in an embodiment, as shown in Figure 2As shown, when the cabinet door assembly 300 is flipped to the maximum angle A relative to the cabinet body assembly 400, the articulation points of the first connecting rod 210 and the output end of the linear drive mechanism 100, the articulation points of the first connecting rod 210 and the fixed bracket 320, and the articulation points of the third connecting rod 230 and the fixed bracket 320 are located on the same straight line, and the linear drive mechanism 100 remains in the powered state, that is, the linear drive mechanism 100 can continuously exert a pushing force along the first direction on the connecting rod assembly 200.

[0050] In this way, on the one hand, due to the continuous operation of the linear drive mechanism 100, and on the other hand, due to the fact that the articulation points of the first connecting rod 210 and the output end of the linear drive mechanism 100, the articulation points of the first connecting rod 210 and the fixed bracket 320, and the articulation points of the third connecting rod 230 and the fixed bracket 320 are located on the same straight line, the connecting rod assembly 200 can be kept in a locked state under the joint action of the two aspects, so as to lock the cabinet door assembly 300 and prevent the cabinet door assembly 300 from rotating and closing.

[0051] However, the application is not limited thereto, and in other embodiments, a special locking structure can also be used to lock the fully opened cabinet door assembly 300.
