[0002] Charging and swapping stations for replacing the batteries of electric vehicles or charging the batteries are widely used. In current charging and swapping stations, the replacement of battery packs is mainly achieved by the back-and-forth movement of the battery swapping device between the electric vehicle and the battery compartment. However, due to the presence of the battery swapping device, there is a need for an access passage between the battery compartment and the outside world. As a result, the battery compartment is connected to the outside, and external sundries, animals, and insects may enter through the access passage, causing damage to the interior of the battery compartment. At the same time, it is not easy to maintain the temperature control inside the battery compartment.

[0003] In existing battery swapping stations, the opening and closing device of the access passage for the battery swapping device also has poor heat preservation performance. When used in some cold regions, the poor heat preservation performance makes it difficult to maintain the temperature control inside the battery compartment, and it is impossible to reach the appropriate working temperature of the battery, affecting the battery performance, charging efficiency, and battery swapping efficiency, and even the normal operation of the battery swapping function. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defect that the opening and closing device in the prior art also has poor heat preservation performance.

[0055] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the accompanying drawings.

[0056] This embodiment provides a battery swapping station, which includes at least one battery compartment and an operation compartment. The battery compartment is used to store batteries and charge the batteries, and the operation compartment is used for an electric vehicle to drive in and replace the battery. The battery swapping station moves between the battery compartment and the operation compartment through battery swapping equipment and completes tasks such as transporting, installing, disassembling, and placing batteries. Due to the requirements of the battery working environment and safety, a lifting door device needs to be set up in the battery swapping compartment to form an openable and closable passage opening. The lifting door device can close the passage opening and open the passage opening when the battery swapping equipment enters and exits the battery swapping station.

[0057] As Figure 1As shown in the figure, this embodiment provides a lifting door device, which includes a door frame 10, a door body 20. The interior of the door body 20 includes a cavity 25, and the cavity 25 is filled with a heat-insulating material (not shown in the figure). The heat-insulating material fills the cavity 25 in the thickness direction of the door body 20. Specifically, the lifting door device of this embodiment is a lifting and lowering type lifting door. Its door frame 10 is arranged on one side of the battery compartment. The door frame 10 includes two longitudinals 11 arranged oppositely and a cross beam 12 connected between the tops of the two longitudinals 11. The door body 20 is arranged between the two longitudinals 11 and is connected to the longitudinals 11 of the door frame 10. The moving direction of the door body 20 is the same as the extending direction of the longitudinal 11. The door body 20 is a hollow structure, and a cavity 25 is formed inside. The cavity 25 is used to fill the heat-insulating material. During filling, it is ensured that the heat-insulating material fills the cavity 25 in the thickness direction, so that both sides of the door body 20 in its thickness direction can be supported by the filled heat-insulating material. By setting the heat-insulating material, the heat preservation effect of the lifting door is enhanced to adapt to the heat preservation requirements of relatively cold regions, so that the appropriate temperature most suitable for the operation of the power battery can be maintained inside the battery swapping station. At the same time, the overall strength of the door body 20 can be improved through the internal filling material, so that the thickness of the plate of the door body 20 can be appropriately reduced, and the overall weight of the door body 20 will not be too heavy while meeting the heat preservation requirements.

[0058] As Figure 3 shown, one side of the door body 20 has an opening 251, and the opening 251 leads to the inside of the cavity 25. The opening 251 is closed by a detachable cover plate 24. Specifically, the door body 20 adopts an openable and closable form, including a door body 201 and a cover plate 24 detachably connected to the door body 201. The cavity 25 is arranged on the door body 201. One side of the door body 201 is open to form an opening 251, and the cover plate 24 can cover the opening 251 to close the cavity 25. By setting the opening 251, it is convenient to fill and remove the heat-insulating material inside the cavity 25, which is convenient for maintenance and installation. In other embodiments, when manufacturing the door body 20, the heat-insulating material is directly filled inside it and then the door body 20 is directly closed without setting a detachable cover plate 24 to obtain better overall strength of the door body 20.

[0059] As Figure 2 、 Figure 3As shown, the opening 251 is provided on one side in the thickness direction of the door body 20. By setting the opening 251 on this side, the area of the cavity 25 opened by the opening 251 can be ensured to be the largest compared with other side surfaces, which is convenient for filling the heat insulation material. At the same time, the heat insulation material is selected as an elastic material. The heat insulation material is placed into the cavity through the opening 251, and the thickness of the heat insulation material in the thickness direction of the door body 20 is greater than the thickness of the cavity so that the end of the heat insulation material exceeds the plane of the opening 251 after being placed into the cavity. By the method of filling the elastic material inside and then pressing the door panel cover plate 24, the elastic material can be deformed to fill the inner cavity and increase the density, thereby improving the overall strength of the door panel. In other embodiments, the opening 251 can also be provided on other side surfaces of the door body 20, but the areas of these side surfaces are smaller, resulting in a corresponding reduction in the area of the opening 251, which is not conducive to filling the heat insulation material. In addition, even if the heat insulation material does not select an elastic material, it can also achieve the effect of filling the inner cavity just by precise filling so that the heat insulation material is exactly the same as the thickness of the cavity 25.

[0060] Preferably, the heat insulation material in this embodiment can be selected as a foaming material. The foaming material has good heat insulation performance and good ductility, which is convenient for deformation.

[0061] As Figure 3 shown, a cavity 25 is formed by inward depression on one side in the thickness direction of the door body 20, and an opening 251 is formed on the surface of this side. Specifically, a cavity 25 is formed by inward depression in the middle area of one side of the door body 201, and there is also a frame around the cavity 25 on this side. The structure of forming the cavity 25 by depression is simple and convenient for processing. The forming method can be selected as integral stamping of a plate, or can be composed of multiple parts spliced together, or can also be formed by bending a sheet.

[0062] As Figure 3 shown, a reinforcing beam 26 is further included in the cavity 25, and the reinforcing beam 26 extends longitudinally. Specifically, the reinforcing beam 26 extends along the vertical direction inside the cavity 25, and both the head and the tail are in contact with the top and the bottom of the door body 20. The vertical support effect can be achieved, and it can cooperate with the support effect in the thickness direction brought by the foaming material to further enhance the overall strength of the door body 20. In this embodiment, the reinforcing beam 26 is a bent plate member, and the whole is in an L shape. Adopting this bent structure can further strengthen the longitudinal strength of the reinforcing beam 26, and can also provide some additional support for the door body 20 in the thickness direction. By the reinforcing beam 26 to make up for the strength loss caused by the cavity 25, the strength of the door body 20 is higher. In other embodiments, other conventional structures of the reinforcing beam 26 can also be selected.

[0063] In this embodiment, multiple groups of heat insulation materials are filled in the cavity 25, and most of the heat insulation materials are distributed along the length direction of the door body 20, and the multiple groups of heat insulation materials are separated by the reinforcing beam 26. Specifically, as Figure 3As shown, a plurality of reinforcing beams 26 are provided in the cavity 25 within the door body 201. The plurality of reinforcing beams 26 divide the inner cavity into a plurality of juxtaposed regions that are isolated from each other, and each region corresponds to a set of heat insulation materials. The two sets of heat insulation materials are separated by the reinforcing beams 26. The heat insulation materials are grouped for easy individual installation, maintenance, and replacement, with better economy.

[0064] As Figures 2 to 4 shown, the cover plate 24 is detachably connected to the door body 20 through the connecting plate 21. Specifically, in this embodiment, the door body 201 is connected and fixed to the cover plate 24 through the connecting plate 21, as Figure 3 shown. At the four corner ends of the door body 201, there are provided cover plate connection parts 241. When the cover plate 24 covers the opening 251 of the door body 201, the cover plate connection parts 241 simultaneously cover the frame at the corner ends of the door body 201 and the corner ends of the cover plate 24 and are respectively fixed to the corner ends of the door body 201 and the corner ends of the cover plate 24, pressing the cover plate 24 against the door body 201 to achieve the fixation of the cover plate 24 to the door body 201, and its fixed state is as Figure 2 shown. The fixation of the cover plate connection parts 241 to the frame at the corner ends of the body and the corner ends of the cover plate 24 is achieved through connecting pieces. The connecting pieces cover the cover plate connection parts 241 and fix the cover plate connection parts 241, the cover plate 24, and the door body 201 by means of bolts. The cover plate 24 is detachably connected to the door body 20 through a single separate structure, making the assembly more convenient.

[0065] As Figure 4 、 Figure 5 shown, the connecting plate 21 is also detachably connected to the cover plate 24 of the door body 20 and the door frame 10 respectively. The connecting plate 21 is detachably connected to the door body 20 and the cover plate 24 respectively to achieve the relative fixation of the cover plate 24 and the door body 20. At the same time, the connecting plate 21 can also play the role of being fixed to the door frame 10, making the structure more robust.

[0066] Specifically, a transmission mechanism 40 for driving the door body 20 to move up and down, a driving mechanism 50 for driving the transmission mechanism 40 to move, and a guiding mechanism 30 for guiding and limiting the moving direction of the door body 20 are provided on the door frame 10 of the lifting door device in this embodiment. The transmission mechanism 40 is specifically a gear pair 42 and a synchronous belt 41 provided on the door frame 10. The door body 20 is fixed to the synchronous belt 41. The driving mechanism 50 drives the gear pair 42 to rotate to drive the synchronous belt 41 to roll, thereby lifting or lowering the door body 20. Both the transmission mechanism 40 and the guiding mechanism 30 are provided on the longitudinal beam 11. Among them, the door body 20 is clamped between two longitudinal beams 11. The transmission mechanism 40 is not provided between the door body 20 and the longitudinal beam 11, but is provided on the mounting surface 111 adjacent to the side of the longitudinal beam 11 facing the door body 20. The guiding mechanism 30 includes a slide rail 31 provided on the mounting surface 111 and a slider 32 slidably engaged with the slide rail 31. The slider 32 is fixedly connected to the door body 20 through a connecting plate 21. Its slide rail 31 and slider 32 are also provided on the mounting surface 111. The slide rail 31 is concave with a sliding groove. The slider 32 is clamped in the sliding groove of the slide rail 31 and is restricted to move only along the extending direction of the slide rail 31, so that it cannot escape from the slide rail 31 in the horizontal direction. The slider 32 is also fixedly connected to both the door body 20 and the synchronous belt 41 at the same time. So that both the transmission mechanism 40 and the guiding mechanism 30 act on the door body 20 through the slider 32. The specific connection structure of the slider 32, the connecting plate 21 and the synchronous belt 41 is as Figure 3 , Figure 4 shown. One end of the connecting plate 21 covers the edge of the door body 20 and is connected to the door body 20. The other end of the connecting plate 21 extends to the mounting surface 111 of the longitudinal beam 11 and the slider 32 and is fixedly connected to the slider 32. The reverse side of the connecting surface of the connecting plate 21 with the slider 32 and the door body 20 is used to connect with the synchronous belt 41. A positioning plate 22 and a fixing plate 23 are provided on the back of the connecting plate 21. A through groove with the same width as the synchronous belt 41 is provided on the positioning plate 22. The synchronous belt 41 is clamped in the through groove. The fixing plate 23 and the connecting plate 21 are respectively connected to both sides of the positioning plate 22 to clamp the synchronous belt 41 therein to complete the fixation. A serrated structure corresponding to the synchronous belt 41 can be provided on one side of the connecting plate 21 and the fixing plate 23, so that it can be coupled with the synchronous belt 41 to achieve better fixation. The slider 32 of the guiding mechanism 30 is connected to the door panel and the synchronous belt 41 at the same time, making the integration of the entire lifting door device higher and the stability better.
