[0038] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, further discussion thereof is not required in subsequent drawings.

[0039] First, the heat-insulating door 1 according to an embodiment of the present utility model will be specifically described below with reference to the accompanying drawings.

[0040] As Figures 1 to 7 shown, the heat-insulating door 1 according to an embodiment of the present utility model includes: a door frame 10 and a door panel 20.

[0041] Specifically, the door frame 10 defines a window 11 adapted for materials to pass through. A plurality of supporting portions 121 are provided on the door frame 10. Each supporting portion 121 has a receiving groove 13, and the notch of the receiving groove 13 is arranged upward. The door panel 20 is covered on one side of the door frame 10. A plurality of support rods 21 and at least one handle 22 adapted to cooperate with the plurality of supporting portions 121 are provided on the door panel 20. The door panel 20 is switchable between a first state and a second state. When the door panel 20 is in the first state, the groove wall surface of the receiving groove 13 supports the support rod 21, and the door panel 20 is hermetically connected to the door frame 10. When the door panel 20 is in the second state, the support rod 21 is separated from the receiving groove 13, and the door panel 20 is separated from the door frame 10. At least one limiting portion 14 protruding toward the door panel 20 is provided on the side of the door frame 10 facing the door panel 20, and the bottom surface of the limiting portion 14 is not higher than the bottom surface of the door panel 20.

[0042] In other words, the heat-insulating door 1 according to the embodiment of the present utility model mainly consists of a door frame 10 and a door panel 20. Among them, the door frame 10 can have a window 11, and the window 11 can be a through hole penetrating the door frame 10 along the thickness direction of the door frame 10. Optionally, the door frame 10 can be approximately square to adapt to the heat-insulating cavities 201 arranged in a rectangular array in the stereoscopic warehouse 100. Goods can pass through the window 11 and enter the storage space.

[0043] The door frame 10 has an inner side surface and an outer side surface in its own thickness direction. The inner side surface of the door frame 10 faces the heat-insulating cavity 201, and the outer side surface of the door frame 10 faces away from the heat-insulating cavity 201. A plurality of supporting parts 121 can be provided on the outer side surface of the door frame 10, and each supporting part 121 can protrude towards the outside of the door frame 10. Each supporting part 121 can be provided with a downwardly concave receiving groove 13, and a supporting rod 21 adapted to the receiving groove 13 can be provided on the door panel 20. The supporting rod 21 can be inserted into the receiving groove 13 from above the receiving groove 13.

[0044] One or more handles 22 are also provided on the door panel 20, and a hook 301 adapted to the handle 22 can be provided on the stacker 3. The hook 301 can lift and then lower the door panel 20 through the handle 22.

[0045] Under the operation of the stacker 3, the door panel 20 can be switched between a first state and a second state so that the heat-insulating door 1 is closed or opened.

[0046] When the door panel 20 is in the first state, the heat-insulating door 1 is closed. The supporting rod 21 on the door panel 20 is received in the receiving groove 13, the supporting part 121 supports the door panel 20, and the door panel 20 is in close fit with the door frame 10 to form a seal. Optionally, the door panel 20 and the door frame 10 can be made of metal materials respectively, and the seal between the door panel 20 and the door frame 10 can be a hard seal.

[0047] When the door panel 20 is in the second state, the heat-insulating door 1 is opened, the supporting rod 21 and the receiving groove 13 can be separated, and the door panel 20 and the door frame 10 are separated. For example, the stacker 3 can lift the door frame 10 by a preset height so that the window 11 of the door frame 10 is completely exposed, facilitating goods to enter the heat-insulating cavity 201 of the stereoscopic warehouse 100.

[0048] During the process of the stacker 3 switching the door panel 20 from the first state to the second state, it is necessary to first lift the door panel 20 upward, then move the door panel 20 towards a position away from the door frame 10, and then continue to lift the door panel 20 to a preset height.

[0049] In addition, a limiting portion 14 may be provided on the door frame 10, and the bottommost surface of the limiting portion 14 is not higher than the bottommost surface of the door panel 20. Since the thermal insulation doors 1 in the automated storage and retrieval system 100 are arranged in a rectangular array in the vertical plane, during the process of the stacker 3 lifting the door panel 20, the door panel 20 in the lower layer of the thermal insulation door 1 can first contact the bottom surface of the limiting portion 14 in the upper layer of the thermal insulation door 1 during the ascending process and be limited by the limiting portion 14.

[0050] Thus, for the thermal insulation door 1 according to the embodiment of the present invention, by using the cooperation of the supporting portion 121 on the door frame 10 and the support rod 21 on the door panel 20, the door panel 20 can be lifted by the stacker 3 to open or close the thermal insulation door 1. At the same time, the limiting portion 14 is provided on the door frame 10, and it is defined that the bottom surface of the limiting portion 14 is not higher than the bottom surface of the door panel 20, so that the lower door panel 20 can be limited by the limiting portion 14 on the upper door frame 10 during the lifting process, avoiding the direct impact of the lower door panel 20 on the upper door panel 20 and preventing the upper door panel 20 from shaking or falling, which is beneficial to improving the safety of the thermal insulation door 1.

[0051] According to an embodiment of the present invention, an avoidance groove 23 is provided at the bottom end of the door panel 20, and the limiting portion 14 is received in the avoidance groove 23 and spaced apart from the door panel 20.

[0052] Specifically, an avoidance groove 23 may be provided at the bottom end of the door panel 20, and the avoidance groove 23 may be recessed upward to provide space for the limiting portion 14 on the door frame 10, and at the same time, it is beneficial to improve the aesthetics of the thermal insulation door 1.

[0053] In addition, the limiting portion 14 and the inner wall surface of the avoidance groove 23 may be spaced apart to form a gap, which can avoid the impact of the door panel 20 on the limiting portion 14 during the falling process, being beneficial to improving the safety and reliability of the thermal insulation door 1. The size of the gap can be set according to actual requirements.

[0054] According to some other embodiments of the present invention, the number of the limiting portions 14 is multiple, and the multiple limiting portions 14 are arranged at intervals in the horizontal direction. Arranging multiple limiting portions 14 in the horizontal direction can limit multiple points of the door panel 20, being beneficial to improving the stability and reliability of the limitation and preventing the lower door panel 20 from becoming unstable and impacting the upper door panel 20 due to single-point limitation.

[0055] In some specific embodiments of the present invention, avoidance grooves 23 are respectively provided at both ends of the door panel 20 in the horizontal direction.

[0056] Such as Figure 5As shown, two avoidance grooves 23 can be provided on the door panel 20. The two avoidance grooves 23 can be spaced apart in the horizontal direction and arranged at the left and right ends of the door panel 20. As a result, the corresponding limiting portions 14 on the door frame 10 can be located at the left and right ends of the window 11, reducing the obstruction of the window 11 space by the limiting portions 14, making it more convenient for goods to enter and exit.

[0057] According to some optional embodiments of the present invention, the inner wall surface of the avoidance groove 23 includes a first wall surface 231 and a second wall surface 232, the first wall surface 231 extends in a horizontal direction, and the second wall surface 232 is arranged at one end of the first wall surface 231 close to the center of the door panel 20 and extends obliquely downward toward the center of the door panel 20.

[0058] Specifically, the inner wall surface of the avoidance groove 23 is mainly composed of a first wall surface 231 and a second wall surface 232. The first wall surface 231 can extend in the horizontal direction, and the second wall surface 232 can be inclined relative to the first wall surface 231, and the angle between the first wall surface 231 and the second wall surface 232 is an obtuse angle. The top end of the second wall surface 232 can be connected to the first wall surface 231, and the bottom end of the second wall surface 232 can be tilted downward and extend toward the horizontal centerline of the door panel 20. This can help the door panel 20 better avoid the limit portion 14 during the falling process, while also improving the aesthetics of the thermal insulation door 1.

[0059] According to some other embodiments of the present invention, there is a smooth transition between the first wall 231 and the second wall 232. For example, Figure 5 As shown, a rounded corner can be provided between the first wall 231 and the second wall 232, which is beneficial to improving the toughness of the door panel 20, reducing stress concentration, facilitating assembly, and at the same time improving aesthetics and safety, and reducing the risk of accidental injury.

[0060] In some specific embodiments of the present invention, a side surface of the limiting portion 14 facing the first wall 231 is parallel to the first wall 231 , and a side surface of the limiting portion 14 facing the second wall 232 is parallel to the second wall 232 .

[0061] Specifically, the cross-section of the stopper 14 obtained by cutting along a vertical plane parallel to the door panel 20 may be a right-angled trapezoid. The outer surface of the stopper 14 may include an upper surface 141, a lower surface 142, a first side surface 143, a second side surface 144, and a third side surface 145. The lower surface 142 may be the bottom surface of the stopper 14.

[0062] The upper surface 141 and the lower surface 142 are spaced apart in the vertical direction, and the upper surface 141 and the lower surface 142 extend in the horizontal direction respectively. Therefore, the upper surface 141 of the limiting portion 14 is coplanar with the first wall surface 231 and is spaced apart in the vertical direction. The first side surface 143, the second side surface 144 and the third side surface 145 are connected in sequence, and the first side surface 143, the second side surface 144 and the third side surface 145 are connected between the upper surface 141 and the lower surface 142. Among them, the first side surface 143 can be parallel to the outer side surface of the door frame 10, and the second side surface 144 can be located on the side of the third side surface 145 away from the center line of the door frame 10. The second side surface 144 can extend in the vertical direction, the third side surface 145 can be parallel to the second wall surface 232, and the third side surface 145 can be spaced apart from the second wall surface 232 to form a gap.

[0063] Thus, by setting the upper surface 141 parallel to the first wall surface 231 and the third side surface 145 parallel to the second wall surface 232, the shape of the limiting portion 14 can be adapted to the shape of the avoidance groove 23. The inclined third side surface 145 is beneficial to better avoid the limiting portion 14 during the falling process of the door panel 20. At the same time, the length of the lower surface 142 can be extended, thereby increasing the contact area between the upper limiting portion 14 and the lower door panel 20, making the limiting of the door panel 20 by the limiting portion 14 more reliable. In addition, the inclined extension of the third side surface 145 is also beneficial to reducing the area of the window 11 occupied by setting the limiting portion 14, facilitating the entry and exit of goods through the window 11.

[0064] According to some alternative embodiments of the present invention, the support rod 21 extends in the horizontal direction, the supporting portion 121 protrudes towards the door panel 20, and the receiving groove 13 penetrates through the supporting portion 121 in the horizontal direction.

[0065] As Figure 7 shown, the supporting portion 121 can protrude towards the outside of the door panel 20, and the supporting portion 121 can be in a hook shape. The support rod 21 can extend in the horizontal direction, and the receiving groove 13 can penetrate through the supporting portion 121 in the horizontal direction to facilitate the entry or exit of the support rod 21 into or out of the receiving groove 13.

[0066] According to other embodiments of the present invention, at least two supporting portions 121 form a supporting group 12, and the multiple supporting portions 121 in the supporting group 12 are arranged at intervals in the vertical direction. Two supporting groups 12 are provided on the door panel 20. When the door panel 20 is in the first state, the door panel 20 is located between the two supporting groups 12.

[0067] Specifically, two supporting groups 12 can be provided on the door frame 10. The two supporting groups 12 can be arranged at intervals in the horizontal direction. Each supporting group 12 can have a plurality of supporting parts 121, and the plurality of supporting parts 121 can be arranged at intervals in the vertical direction. The support rods 21 on the door panel 20 can be arranged in one-to-one correspondence with the supporting parts 121 on the door frame 10.

[0068] For example, as Figure 1 shown, each supporting group 12 can have two supporting parts 121, or as Figure 7 shown, each supporting group 12 can have three supporting parts 121. Arranging a plurality of supporting parts 121 in each supporting group 12 is beneficial to improving the stability and reliability of the connection between the door panel 20 and the door frame 10. When the heat preservation door 1 is in the closed state, the door panel 20 can be located between the two supporting groups 12.

[0069] In some specific embodiments of the present invention, a reflective coating 25 is provided on the side of the door panel 20 away from the door frame 10. A sensor capable of detecting the reflective coating 25 can be provided on the stacker 3. The position of the heat preservation door 1 can be judged by using the reflective coating 25, so as to facilitate the stacker 3 to operate on the door panel 20.

[0070] Optionally, reflective coatings 25 can be respectively provided in two horizontally spaced regions on the outer surface of the door panel 20. The position and attitude of the door panel 20 can be judged by using the reflective coatings 25 in these two regions.

[0071] According to some optional embodiments of the present invention, a first reinforcing rib 15 is provided on the side of the door panel 20 away from the door frame 10, and a second reinforcing rib 25 is provided on the side of the door frame 10 away from the door panel 20. This is beneficial to strengthening the strength of the door panel 20 and the door frame 10 and improving the reliability of the heat preservation door 1. Optionally, the first reinforcing rib 15 and the second reinforcing rib 25 can respectively include a plurality of rib portions extending in the horizontal direction and / or the vertical direction.

[0072] The embodiment of the present invention also provides a stereoscopic warehouse 100, which includes the heat preservation door 1, the shelf 2 and the stacker 3 according to any one of the above embodiments.
