Description

TECHNICAL FIELD

[0001] The present application relates to the field of battery replacement of electric vehicles, in particular to a box and a battery replacement station comprising the same. BACKGROUND

[0002] The battery replacement station is used for replacing batteries of electric vehicles. After the electric vehicle is reliably positioned in the battery replacement station, the battery replacement equipment replaces the batteries of the electric vehicle. Specifically, the battery replacement trolley takes the batteries to be replaced on the electric vehicle and places them on the stacker, and then the stacker transports the batteries to be replaced to the charging rack. The stacker takes the new batteries charged on the charging rack and places them on the battery replacement trolley, and then the battery replacement trolley transports the new batteries to the predetermined position and mounts them on the electric vehicle.

[0003] Patent No. CN211684751U discloses a battery replacement station. This battery replacement station is a whole box type battery replacement station. When the battery replacement station is put into use and the charging bin capacity is not enough, it is difficult to expand the capacity. In the case of having to expand the capacity, only a whole box body can be added beside or above the battery replacement station. If the different box bodies need to be connected for convenient battery transportation, the frame of the original battery replacement station needs to be cut and opened, which is very inconvenient and is not conducive to the safety of the battery replacement station.

Thus, the battery replacement station has high expandability;

Moreover, since the modules are assembled by parts, the sizes of the parts are relatively small, the surface treatment of the parts can be performed in advance, for example, by using electrophoresis, so that the surface treatment effect of the parts is better and the corrosion resistance of the battery swap station is improved.

[0011] Thirdly, since the battery swap station is assembled in a factory building, the space and position of internal equipment and lines can be reserved according to actual needs when the battery swap station is built, which is beneficial to the reasonable layout of the internal structure and equipment of the battery swap station.

[0012] Fourthly, since the box is only a frame structure, the protection plate can be installed on the outside of the box to form the whole battery swap station.

[0042] Preferably, the third stand is reused as a guide column of a battery transfer device, and a guide surface is arranged on the third stand to guide the battery transfer device to move up and down along the third stand.

[0043] In this scheme, the third stand is also used as a guide column of a battery transfer device, so that the battery transfer device moves up and down along the third stand. Compared with the scheme of using a stacking machine to realize the transfer of battery packs, the track for the stacking machine is saved, and the demand for height space is reduced. At the same time, since the third stand is reused, the guide column required for the lifting movement of the battery transfer device does not need to be additionally arranged, and the demand for horizontal space is reduced.

[0044] Preferably, the sub-frame comprises a plurality of oppositely arranged connecting horizontal beams and a plurality of oppositely arranged connecting vertical beams, and the plurality of connecting horizontal beams and the plurality of connecting vertical beams are cross-connected to form the sub-frame.

[0055] Preferably, the first protective plate is detachably connected with the frame structure of the battery storage area.

[0056] In the scheme, when an emergency situation occurs, such as a battery pack temperature being too high, the battery pack can be quickly transferred to the outside of the box body by detaching the first protective plate. Meanwhile, when the battery replacement station needs to be expanded after being built, the expansion of the battery replacement station can be realized by detaching the first protective plate.

At the same time, since the box frame is not blocked and facilitates electrical connection after expansion, the expansion box is powered, so that the battery swap station has high expandability;

[0063] Secondly, since the box frame of the battery swap station is assembled by assembling each module, each module can be assembled at the same time, so that the battery swap station can be quickly formed and has high construction efficiency. Since each module is assembled by each part, the size of each part is relatively small, and the surface treatment of each part can be performed in advance, for example, by using electrophoresis, so that the surface treatment effect of each part is better, and the corrosion resistance of the battery swap station is improved;

[0064] Thirdly, since the battery swap station is assembled in the factory building, the space and position of the internal equipment and lines can be reserved according to the actual needs during construction, which is beneficial to the reasonable layout of the internal structure and equipment in the battery swap station;

[0116] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments.

[0117] Example 1

[0118] This embodiment discloses a housing for constructing a battery swapping station. For example... Figures 1-11 As shown, the enclosure includes two battery storage areas 100 located at both ends and a middle battery swapping area 200. The battery storage areas 100 are frame structures. The middle battery swapping area 200 is also a frame structure and is located between the two battery storage areas 100. The middle battery swapping area 200 consists of one opposite side of the two battery storage areas 100 and a top assembly 300 and a bottom assembly 400 connecting the two battery storage areas 100.

[0119] In the embodiment, the box body can be first formed with two battery storage areas 100 respectively, and then the top assembly 300 and the bottom assembly 400 are connected to the two battery storage areas 100 respectively to form the intermediate battery replacement area 200, so that the box body can be quickly formed. The effects of this scheme are described as follows:

[0120] First, since the battery replacement station is formed by the assembled box body frame, when expansion is needed, the expansion box body can be quickly extended along each expandable direction of the battery replacement station, so that the battery capacity of the battery replacement station can be conveniently and quickly expanded. At the same time, since the box body frame is not blocked and facilitates electrical connection after expansion, the expansion box body is convenient to power on. Therefore, the battery replacement station has high expandability;

[0121] Second, since the box body frame of the battery replacement station is formed by assembling each module, each module can be assembled at the same time, so that the battery replacement station can be quickly formed and has high construction efficiency. Since each module is assembled by each part, the size of each part is relatively small, and the surface treatment of each part can be performed in advance, for example, by using electrophoresis, so that the surface treatment effect of each part is better and the corrosion resistance of the battery replacement station is improved;

[0122] Third, since the battery replacement station is assembled in a factory building, the space and position of internal equipment and lines can be reserved according to actual needs when the battery replacement station is built, which is beneficial to the reasonable layout of internal structures and equipment in the battery replacement station;

[0123] Fourth, since the box body is only a frame structure, the protection plate can be installed on the outside of the box body to form the whole battery replacement station. When the temperature of the battery is too high, the battery can be directly removed or ejected from the inside by removing or ejecting the protection plate.

[0124] In an optional embodiment, as shown in Figures 1-5 The frame structure of the battery storage area 100 includes a first battery carrying area frame 10, a battery transfer area frame 20 and a second battery carrying area frame 30 which are assembled respectively and connected in sequence, wherein the first battery carrying area frame 10 is adjacent to the intermediate battery replacement area 200 and is connected to the top assembly 300 and the bottom assembly 400.

[0125] Among them, the first battery carrying area frame 10, the battery transfer area frame 20 and the second battery carrying area frame 30 can be formed respectively and individually, since each frame structure can be assembled at the same time and then assembled to form the battery storage area 100, which is beneficial to the quick formation of the box body.

[0126] In another optional embodiment, as shown in Figures 1-2As shown in FIG. 1, the top assembly 300 and the bottom assembly 400 extend at least to the battery transfer area frame 20 in the transverse direction, and the battery transfer area frame 20 is connected to the top assembly 300 and the bottom assembly 400.

[0127] In the above two optional embodiments, the first uprights 103 and the second uprights 303 are beneficial to reliably support the first top longitudinal beam 101, the first bottom longitudinal beam 102, the second top longitudinal beam 301, and the second bottom longitudinal beam 302, and are beneficial to guarantee the reliability of the first battery carrying area frame 10 and the second battery carrying area frame 30, and are also beneficial to realize the connection with the battery transfer area frame 20. Meanwhile, a plurality of battery carrying racks can be further arranged between the two first uprights 103 or between the two second uprights 303 in the vertical direction to store batteries.

[0128] In another optional embodiment, as shown in FIG. 1, Figures 1-3 and Figure 9 As shown in FIG. 1, the first battery carrying area frame 10 includes a first top longitudinal beam 101, a first bottom longitudinal beam 102, and at least two first uprights 103. The first top longitudinal beam 101 and the first bottom longitudinal beam 102 are respectively connected to the top assembly 300 and the bottom assembly 400. The at least two first uprights 103 are connected between the first top longitudinal beam 101 and the first bottom longitudinal beam 102, and are fixedly connected with the battery transfer area frame 20.

[0129] In another optional embodiment, as shown in FIG. 1, Figures 1-5 , Figures 7-8 As shown in FIG. 1, the second battery carrying area frame 30 includes a second top longitudinal beam 301, a second bottom longitudinal beam 302, and at least two second uprights 303. The second top longitudinal beam 301 and the second bottom longitudinal beam 302 are respectively connected to the top assembly 300 and the bottom assembly 400. The at least two second uprights 303 are connected between the second top longitudinal beam 301 and the second bottom longitudinal beam 302, and are fixedly connected with the battery transfer area frame 20.

[0130] In the above two optional embodiments, the at least two first uprights 103 and the at least two second uprights 303 are beneficial to reliably support the first top longitudinal beam 101, the first bottom longitudinal beam 102, the second top longitudinal beam 301, and the second bottom longitudinal beam 302, are beneficial to guarantee the reliability of the first battery carrying area frame 10 and the second battery carrying area frame 30, and are also beneficial to realize the connection with the battery transfer area frame 20. Meanwhile, a plurality of battery carrying racks can be further arranged between the two first uprights 103 or between the two second uprights 303 in the vertical direction to store batteries.

[0131] It should be noted that the first uprights 103 and the second uprights 303 can adopt the same structure, or can be set as different structures according to actual needs.

[0132] In another optional embodiment, as shown in FIG. 1, Figures 1-10 the first uprights 103 and the second uprights 303 have the same structure, Figure 10The structure of the second stand 303 is shown schematically. Specifically, the first stand 103 and the second stand 303 each include a first vertical beam 304, two first horizontal beams 305, and a plurality of first reinforcing bars 306. The two ends of the first vertical beam 304 are respectively connected to one end of a first horizontal beam 305, and the other end of the first horizontal beam 305 has a first connecting structure. The first vertical beam 304 and the first horizontal beam 305 form a frame with a first opening. The plurality of first reinforcing bars 306 are arranged in the frame of the corresponding first stand 103 or second stand 303. The first end of the first reinforcing bar 306 is fixedly connected to the frame, and the second end of the first reinforcing bar 306 is a free end (i.e., the second end is not fixedly connected to other components) and is configured to have a second connecting structure.

[0133] By configuring the frame with the first opening, the structure is simpler while ensuring support strength. In addition, by arranging the first reinforcing bars 306, the corresponding first stand 103 and second stand 303 can be reinforced. Through the first connecting structure and / or the second connecting structure, the first stand 103 and the second stand 303 can be quickly and easily assembled with other components, facilitating the quick assembly of the box body and improving the overall reliability of the box body while simplifying the structure of the box body.

[0134] In another optional embodiment, as shown in Figure 10 the second end of the first reinforcing bar 306 extends towards the first opening, and the second end of the first reinforcing bar 306 is located on the same vertical plane as the end of the first horizontal beam 305 away from the first vertical beam 304. In this way, on the one hand, the second end of the first reinforcing bar 306 does not protrude from the first horizontal beam 305, preventing the first reinforcing bar 306 from interfering with other external structures and facilitating the splicing with the external structures. On the other hand, when splicing with the external structures, the second end of the first reinforcing bar 306 can be aligned with the external structures, further strengthening the structure.

[0135] In another optional embodiment, as shown in Figure 10 the plurality of first reinforcing bars 306 are arranged in a cross shape. The first end of the first reinforcing bar 306 is connected to the first vertical beam 304 and / or the first horizontal beam 305.

[0136] The first reinforcing bars 306 are arranged in a cross shape, further strengthening the structure. The reinforcing bars are connected to the first vertical beam 304 and the first horizontal beam 305, and the stress and strain of different parts of the frame can be transmitted to each other, dispersing the stress.

[0137] The first stand 103 includes a closed triangular structure formed by any combination of the first reinforcing bar 306, the first vertical beam 304, and the first horizontal beam 305. As shown in Figure 10 two intersecting first reinforcing bars 306 and the first vertical beam 304 form a triangular structure.

[0138] The triangular structure is stable and beneficial to further strengthen the structure.

[0139] It should be noted that in alternative embodiments, the first stand 103 can be provided with other structures composed of any combination of the first reinforcing rib 306, the first vertical beam 304 and the first horizontal beam 305, such as a rhombus, according to actual needs.

[0140] In another alternative embodiment, as shown in Figures 1-6 The battery transfer area frame 20 includes two sub-frames 201 at the top and bottom respectively and at least two third stands 202 connected between the two sub-frames 201. The at least two third stands 202 are beneficial to reliably support the two sub-frames 201 and ensure the reliability of the battery transfer area frame 20.

[0141] Regarding the structure of the third stand 202, in an embodiment, the third stand 202 can be provided with a first column, and the first column is provided with a third connecting structure connected with the first battery carrying area frame 10 and the second battery carrying area frame 30. In this way, the structure of the box body is simplified, and the structure of the box body is further strengthened. The third connecting structure facilitates the connection of the third stand 202 with the first battery carrying area frame 10 and the second battery carrying area frame 30, and can further strengthen the first battery carrying area frame 10 and the second battery carrying area frame 30.

[0142] As shown in Figures 4-6 , Figure 8 In alternative embodiments, the third stand 202 includes a plurality of second reinforcing ribs 203 and two second vertical beams 204 arranged oppositely, the plurality of second reinforcing ribs 203 are located between the two second vertical beams 204 and connect the two second vertical beams 204 into one. The second vertical beam 204 is provided with a third connecting structure connected with the first battery carrying area frame 10 and the second battery carrying area frame 30.

[0143] In this way, the structure of the box body is simplified, and the structure of the box body is further strengthened by providing reinforcing ribs. The third connecting structure facilitates the connection of the third stand 202 with the first battery carrying area frame 10 and the second battery carrying area frame 30, and can further strengthen the first battery carrying area frame 10 and the second battery carrying area frame 30.

[0144] It should be noted that in alternative embodiments, the third stand 202 can be provided with any other support and strengthening structure suitable for this purpose, such as the same structure as the first stand 103 or the second stand 303.

[0145] Correspondingly, as shown in Figures 4-6 ,Figure 8 As shown, the plurality of second reinforcing ribs 203 are cross arranged. The plurality of second reinforcing ribs 203 form a grid structure. The cross arrangement and the grid structure of the second reinforcing ribs 203 can further strengthen the structure. Corresponding to the first reinforcing ribs 306, the structural features of the aforementioned plurality of first reinforcing ribs 306 can also be applicable to the second reinforcing ribs 203.

[0146] In addition, it should be noted that, as Figures 4-5 As shown, the second vertical beams 204 of the adjacent third vertical stands 202 and the first vertical stands 103 and / or the second vertical stands 303 are shared, that is, the second vertical beams 204 of the third vertical stands 202 close to the first vertical stands 103 and / or the second vertical stands 303 are connected to the first horizontal beams 305 through the corresponding connecting structures. In this way, the support or reinforcement effect can be further improved on the basis of simplifying the number of parts.

[0147] In another optional embodiment, the second vertical beams 204 of the third vertical stands 202 are reused as guide columns of the battery transfer device, and guide surfaces are arranged on the second vertical beams 204 to guide the battery transfer device to move up and down in cooperation with the battery transfer device. For example, the guide surfaces can be flat or surfaces matched with the wheels of the battery transfer device, or can be guide rails or guide grooves.

[0148] Among them, the second vertical beams 204 are also used as guide columns of the battery transfer device, so that the battery transfer device moves up and down along the second vertical beams 204. Compared with the scheme of using a stacking machine to realize the transfer of battery packs, the track for the stacking machine is saved, and the demand for height space is reduced. At the same time, due to the reuse of the second vertical beams 204, the guide columns required for the up and down movement of the battery transfer device do not need to be additionally arranged, and the demand for horizontal space is reduced.

[0149] In addition, it should be noted that, as Figure 8 As shown, the two second vertical beams 204 of one third vertical stand 202 of the battery transfer area frame 20 are respectively connected with the two first horizontal beams 305 of the second vertical stands 303 of the second battery carrying area frame 30. In this way, the reinforcement effect can be further improved on the basis of simplifying the structure of the box.

[0150] In another optional embodiment, as Figures 1-2 , Figures 4-6 As shown, the sub-frame 201 includes a plurality of oppositely arranged connecting horizontal beams 205 and a plurality of oppositely arranged connecting vertical beams 206, and the plurality of connecting horizontal beams 205 and the plurality of connecting vertical beams 206 are cross connected to enclose the sub-frame 201. The sub-frame 201 has a simple structure and can be quickly assembled, thereby facilitating the quick assembly of the box.

[0151] In another optional embodiment, as Figures 1-2As shown, the top assembly 300 comprises at least two top cross beams 3001 arranged at intervals, and each of the at least two top cross beams 3001 is connected to the top of the frame of the battery storage area 100. The bottom assembly 400 comprises at least two bottom cross beams 401 arranged at intervals, and each of the at least two bottom cross beams 401 is connected to the bottom of the frame of the battery storage area 100. In this way, the top assembly 300 and the bottom assembly 400 are simple in structure and can be quickly assembled, thereby facilitating the quick assembly of the box.

[0152] In another optional embodiment, the intermediate battery replacement area 200 further comprises a column assembly, the column assembly comprises a plurality of second columns 500 arranged at intervals, the column assembly is connected between the top assembly 300 and the bottom assembly 400, and the column assembly is arranged adjacent to the two battery storage areas 100. In this way, a more reliable support effect can be achieved with a relatively simple structure, thereby facilitating the simplification of the structure of the box and ensuring the overall stability of the box. At the same time, the area of the second column 500 to the battery storage area 100 and the area of the first battery carrying area frame 10 can constitute an area for the battery replacement device to enter, facilitating the entry of the battery replacement device to transfer the battery.

[0153] It should be noted that the first connecting structure, the second connecting structure and the third connecting structure described in the present application can be any structure that can achieve the connection of the corresponding structural members. Taking the connection between the first stand 103 and the second vertical beam 204 of the third stand 202 as an example, the first connecting structure of the end of the first cross beam 305, the second connecting structure of the end of the first reinforcing rib 306, and the third connecting structure arranged on the second vertical beam 204 can be set to, but are not limited to:

[0154] The first connecting structure and the second connecting structure are first clamping parts, and the third connecting part is a second clamping part, and the first clamping part and the second clamping part are clamped and connected.

[0155] In addition, it should be noted that the number of structural members such as the first stand 103, the second stand 303 and the third stand 202, and the second column 500 shown in the figures is only illustrative, and in fact, the number of structural members in the present application can be set to any other number within the defined number range according to actual needs.

[0156] In optional embodiments, as shown, Figure 11 As shown, the box further comprises a first protective plate 600 and a second protective plate 700, wherein the first protective plate 600 is arranged outside the frame structure of the aforementioned two battery storage areas 100, and the second protective plate is arranged outside the frame structure of the aforementioned intermediate battery replacement area 200.

[0157] Among them, the first protective plate 600 and the second protective plate protect the inside of the box, which is conducive to ensuring the reliability of battery replacement.

[0158] In another optional embodiment, the first protective plate 600 is arranged to be detachably connected with the frame structure of the battery storage area 100. When a sudden situation occurs, such as the temperature of the battery pack being too high, the battery pack can be quickly transferred to the outside of the box by detaching the first protective plate 600. At the same time, when the battery swap station needs to be expanded after being built, it can be realized by detaching the first protective plate 600, thereby improving the expandability of the battery swap station.

[0159] In addition, for the first protective plate 600 and the second protective plate 700, at least the first protective plate 600 is made of heat preservation and insulation material. The first protective plate 600 corresponds to the frame structure of the battery storage area 100, and the first protective plate 600 is made of heat preservation and insulation material, which has good protection effect and is beneficial to further ensure the temperature control in the battery storage area and ensure that the battery is in the most suitable working environment.

[0160] It should be noted that the second protective plate corresponds to the frame structure of the intermediate battery swap area 200, and compared with the frame structure of the battery storage area 100, the intermediate battery swap area 200 has relatively low requirements for heat preservation and insulation performance. Therefore, the first protective plate 600 can have higher requirements for the material in terms of heat preservation and insulation than the second protective plate.

[0161] The application also provides a battery swap station comprising the box. Since the box can be quickly formed and the surface quality is easy to control, the battery swap station comprising the box can also be quickly formed and the surface quality is easy to control.

[0162] The battery swap station comprises two battery charging rack assemblies, a battery transfer device, and a battery swap device. The two battery charging rack assemblies are arranged in the frame structure of the two battery storage areas 100. The battery charging rack assembly is formed by a plurality of vertically arranged battery carrying racks arranged between the two opposite first stands 103 or the two second stands 303. The battery transfer device is located in the battery transfer area frame 20, and the two rows of battery racks are located in the first battery carrying area frame 10 and the second battery carrying area frame 30, respectively. The bottom assembly 400 is also provided with a guide assembly for guiding the movement of the battery swap device. Specifically, as shown in the figure, the guide assembly comprises two oppositely arranged tracks 800, and the track 800 is preferably arranged on the two bottom cross beams 401. Figures 1-2

[0163] ​The box body can be firstly formed with two battery storage areas 100 respectively, and then the top assembly 300 and the bottom assembly 400 are connected to the two battery storage areas 100 respectively to form the intermediate battery replacement area 200, so that the box body can be quickly formed. In addition, compared with the box body of the battery replacement station formed by the container assembly in the prior art, the box body in the application can select a suitable surface quality treatment method according to the needs, and the surface quality is relatively easy to control. Correspondingly, the battery replacement station containing the box body can be quickly formed, and the surface quality is relatively easy to control.
