Description

TECHNICAL FIELD

[0001] The present application relates to the field of battery replacement of electric vehicles, in particular to an assembly method of a battery replacement station or energy storage station. 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 off 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 off 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 kind of 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 can be added beside or above the original battery replacement station. If the different boxes 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. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the above-mentioned defects in the prior art and provide an assembly method of a battery replacement station or energy storage station.

[0008] Assembling a battery charging rack component and mounting two battery charging rack components on the bottom component, and positioning the two battery charging rack components at both ends of the bottom component;

[0009] Assembling a top component and mounting the top component on the top of the two battery charging rack components.

[0010] In the present scheme, first, the battery swap station or energy storage station is formed by assembling a bottom assembly, a top assembly and a battery charging rack assembly into a box frame. When expansion is needed, the box frame can be quickly extended and assembled along each expandable direction of the battery swap station or energy storage station to conveniently and quickly expand the battery capacity of the battery swap station or the storage space of the energy storage station. At the same time, the box frame is not obstructed, which facilitates the electrical connection after expansion and the power supply of the extended box, so that the battery swap station or energy storage station has high expandability.

[0138] 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.

[0139] Example 1

[0140] This embodiment discloses a casing for a battery swapping station or energy storage station, such as... Figures 1-13 As shown, the box has a frame structure and includes: a top component 500 located at the top of the box; a bottom component 100 located at the bottom of the box; and two battery charging rack components 200 located at both ends of the box, with the two battery charging rack components 200 connected to the top component 500 and the bottom component 100 respectively.

[0141] In this embodiment, firstly, the battery swapping station or energy storage station is formed by assembling a box frame consisting of a bottom component 100, a top component 500, and a battery charging rack component 200. When expansion is required, the expansion box can be quickly extended and assembled along each expansion direction of the battery swapping station or energy storage station, thereby conveniently and quickly expanding the battery capacity of the battery swapping station or the storage space of the energy storage station. At the same time, since the box frame is unobstructed, it facilitates electrical connections after expansion and makes it easy to power on the expansion box, thus the battery swapping station or energy storage station has high scalability.

[0142] Secondly, the enclosure can be constructed by first molding the bottom component 100, top component 500, and battery charging rack component 200 separately, and then connecting them. Since each module, including the bottom component 100, top component 500, and battery charging rack component 200, can be assembled simultaneously, the battery swapping station or energy storage station can be rapidly constructed with high efficiency. Furthermore, since each module is assembled from individual components, and these components are relatively small, their surfaces can be pre-treated, such as by electrophoresis, resulting in better surface treatment and improved corrosion resistance of the battery swapping station.

[0143] Third, since the battery swapping station or energy storage station containing the above-mentioned box is assembled, space and location for internal equipment and lines can be reserved according to actual needs during construction, which is conducive to the reasonable layout of the internal structure and equipment of the battery swapping station or energy storage station.

[0144] Fourth, since the enclosure is only a frame structure, a battery swapping station or energy storage station can be formed by installing a detachable protection plate 700 on the outside of the enclosure. When the battery temperature is too high, the battery or internal contents can be directly removed from the battery swapping station by removing or pushing out the protection plate 700 from the inside, thereby improving the safety of the battery swapping station or energy storage station.

[0145] It should be noted that, Figure 1 only one side of the battery charging rack assembly 200 is shown schematically, and the top assembly 500 is also a schematic expression. As Figure 1 shown, when the box is the box of the battery swap station, the battery swap station further comprises a battery swap area 900, which is arranged between the two battery charging rack assemblies 200 and is surrounded by the opposite sides of the two battery charging rack assemblies 200, the top assembly 500 and the bottom assembly 100. Among them, the position where the two battery charging rack assemblies are located corresponds to the battery storage area 800. Among them, the battery storage area 800 and the battery swap area 900 are functional divisions of the area of the battery swap station.

[0146] In an optional embodiment, as Figures 1-3 shown, the battery charging rack assembly 200 comprises at least one battery charging rack, the battery charging rack comprises a top frame, a bottom frame, at least two columns 2001 connecting the top frame and the bottom frame, and a plurality of battery carrying racks 2002 arranged in the vertical direction between the top frame and the bottom frame, the top frame is connected with the top assembly 500, and the bottom frame is connected with the bottom assembly 100.

[0147] Among them, the structure of the battery charging rack assembly 200 is simple, which is convenient for faster forming and connecting with the corresponding top assembly 500 and bottom assembly 100, and the stability of the battery charging rack assembly 200 is higher, which is conducive to realizing more reliable support.

[0148] The battery charging rack is not limited to the structure described above, and in some embodiments, it can be replaced by any form of battery charging rack.

[0149] It should be noted that, Figure 1 and Figure 3 only the structure and number of the battery carrying rack 2002 are shown schematically, and in fact, according to actual needs, the specific structure form and number of the battery carrying rack 2002 can be set arbitrarily on the basis of strength and space.

[0150] In another optional embodiment, as Figure 1 and Figure 3 shown, each battery charging rack assembly 200 comprises two rows of battery charging racks arranged at intervals in a first direction, and the battery charging racks are respectively connected and fixed with the top assembly 500 and the bottom assembly 100, and the first direction is the length direction or the width direction of the box.

[0151] In the process of installing the top assembly 500, the battery charging rack assembly 200 supports the top assembly 500, each battery charging rack assembly 200 is arranged to include two rows of battery charging racks, which is conducive to improving the reliability of the support, the capacity of the battery pack, and the space utilization of the box.

[0152] In another optional embodiment, as shown in Figure 1 The battery charging rack assembly 200 further includes a first reinforcing support 600 connected to the two rows of battery charging racks arranged at intervals along the first direction.

[0153] The battery charging rack plays a major supporting role, and the first reinforcing support 600 is added between the two rows of battery charging racks, which is conducive to ensuring the strength in the transverse direction and achieving reliable support, thereby ensuring the stability of the box.

[0154] The structure of the first reinforcing support 600 is not limited, for example, the first reinforcing support 600 can include at least one reinforcing rod, or a reinforcing frame including a reinforcing rod and a reinforcing rib connected to the reinforcing rod. In fact, the first reinforcing support 600 can adopt any reinforcing structure suitable for this purpose.

[0155] Therefore, the structure of the first reinforcing support 600 can be relatively simple, which is conducive to simplifying the structure of the box while ensuring the stability of the box.

[0156] In another optional embodiment, the first reinforcing support 600 is arranged between the adjacent columns 2001 of the two rows of battery charging racks; or, the first reinforcing support 600 is arranged to extend through the two rows of battery charging racks along the first direction (as shown in Figure 1 Thus, the arrangement can further improve the supporting effect of the battery charging rack assembly 200 and ensure the overall stability of the box. If the first reinforcing support 600 is directly arranged between the adjacent columns 2001, on the one hand, there is no need to additionally arrange a connecting carrier, which is conducive to simplifying the structure; on the other hand, it does not easily affect the normal operation or use of other structural members while improving the space utilization. The first reinforcing support 600 is arranged to extend through the two rows of battery charging racks as shown in Figure 1 The structure of the first reinforcing support 600 is relatively simple, the reinforcing effect is good, and it does not occupy the space inside the box, which is also conducive to achieving the connection with the battery charging rack.

[0157] In another optional embodiment, the first reinforcing support 600 can be arranged to be connected to the top assembly 500 and / or the bottom assembly 100.

[0158] The first reinforcing support 600 is arranged at the top and / or the bottom and does not easily interfere with the normal operation of other structural members. Meanwhile, the first reinforcing support 600 is additionally connected to the top assembly 500 and / or the bottom assembly 100, which is beneficial to further reinforce the connection between the battery charging rack and the top assembly 500 and the bottom assembly 100, thereby, it is beneficial to further improve the supporting effect of the battery charging rack assembly 200, and further improve the overall stability of the box body.

[0159] In addition, it should be noted that in order to improve the overall reliability of the box body, a plurality of second reinforcing supports can also be arranged on the top assembly 500 and the bottom assembly 100 according to actual needs, and the plurality of second reinforcing supports are arranged around the outside of the two battery charging rack assemblies 200. Similar to the first reinforcing support 600, the structure of the second reinforcing support can adopt any reinforcing structure suitable for this purpose.

[0160] As shown in Figure 1 , Figure 3 , Figures 11-13 The top assembly 500 includes two top units 501 at both ends, which correspond to the two battery charging rack assemblies 200. Since the energy storage station only includes the battery storage area 800, it is only necessary to connect the two top units 501 corresponding to the two battery storage areas 800 or the two battery charging rack assemblies 200 to each other, or the two top units can be directly integrated. As an illustrative embodiment, the top unit 501 is a frame structure, and the top unit 501 frame structure is provided with at least one first connecting beam 507 and at least one second connecting beam 508 in the plane of the frame structure, and the first connecting beam 507 and the second connecting beam 508 are arranged in cross or perpendicular. The battery charging rack assembly 200 is connected to the first connecting beam 507 and / or the second connecting beam 508.

[0161] The structure of the top unit 501 is relatively simple and stable, which is beneficial to the rapid assembly of the first top unit 501 and simplifies the structure of the box body and the battery swap station or the energy storage station.

[0162] In an optional embodiment, as shown in Figures 11-13 A support beam 502 can also be arranged in the frame structure of the first top unit 501, and the support beam 502 is connected to at least one of the first connecting beam 507 and the second connecting beam 508. The extension direction of the support beam 502 is the length direction of the support beam 502, and at least one accommodating groove 503 is arranged at intervals along the width direction of the support beam 502, and the accommodating groove 503 is provided with a wire bundle passing accommodating hole (not shown in the figure) at both ends along the length direction of the support beam 502.

[0163] The accommodating grooves 503 are arranged in the support beam 502, which is beneficial to protect the wire harness and prevent other structural members from damaging the wire harness during installation or operation. In addition, when the number of accommodating grooves is multiple, it is not only beneficial to more reasonably and reliably accommodate the wire harness, but also convenient to realize connection with other structural members at the bottom of the support beam 502.

[0164] In another optional embodiment, along the width direction of the support beam 502, the support beam 502 is provided with at least one mounting portion which can be arranged at intervals, and the mounting portion is provided with a first connecting structure for connecting and fixing the top protective plate 700.

[0165] The first connecting structure on the mounting portion can realize quick installation with the top protective plate 700, which is beneficial to quick assembly and production of the battery swap station or the energy storage station, and is beneficial to improve the production rhythm.

[0166] As shown in Figures 11-13 The support beam 502 has at least one protruding portion 505 arranged at intervals, and the mounting portion of the support beam 502 is located on the protruding portion 505.

[0167] The mounting portion is located at a higher position under the action of the protruding portion 505, which can facilitate quick installation with the top protective plate 700, and can also not affect the accommodation of the wire harness.

[0168] In another optional embodiment, the extension direction of the support beam 502 is the length direction of the support beam 502, and along the length direction of the support beam 502, both sides of the support beam 502 have horizontal extension portions 506.

[0169] On the one hand, the horizontal extension portion 506 can improve the strength of the support beam 502; on the other hand, through the horizontal extension portion 506, the connection of the support beam 502 with external structural members can be facilitated.

[0170] In an optional embodiment, the support beam 502 is formed by bending a sheet metal member. The support beam 502 is formed by bending a sheet metal member, and the forming mode of the support beam 502 is relatively simple, which is convenient for forming and has high strength and low cost.

[0171] As shown in Figures 11-13 The top unit further includes a busbar 509 which is arranged in the frame structure and is arranged at intervals with the support beam 502. With the above structure, the internal equipment of the battery swap station or the energy storage station can be conveniently connected to electricity, the busbar 509 will not affect the normal accommodation of the wire harness, and the existence of the busbar 509 also plays a certain limiting role on the wire harness.

[0172] In another optional embodiment, the first connecting beam 507 and / or the second connecting beam 508 can adopt the same structure as the support beam 502, that is, the first connecting beam 507 and / or the second connecting beam 508 are provided with a receiving groove for accommodating the wire harness along the respective length direction. Further, the first connecting beam 507 and / or the second connecting beam 508 are provided with at least one first mounting portion, which is arranged upward and used for connecting the protective plate 700 of the top surface of the cabinet.

[0173] The wire harness is accommodated in the frame of the top unit 501, so that the wire harness can be hidden at the top of the battery swap station, without occupying additional space in the station, especially the space on the side and bottom, without the need to avoid the structures and equipment in the station, and facilitating the wiring in the station. At the same time, the first connecting beam 507 and the second connecting beam 508 can not only support other structural members, but also strengthen the frame of the top assembly 500, and can also accommodate the wire harness, which is beneficial to simplify the structure of the top assembly 500 and the battery swap station and the energy storage station. In addition, the arrangement of the wire harness at the top provides the possibility of expanding the capacity of the cabinet upward and the convenience of power supply to the upper cabinet.

[0174] Further, the installation portion is arranged on the first connecting beam 507 and / or the second connecting beam 508, which can realize the quick installation of the first connecting beam 507 and / or the second connecting beam 508 with the protective plate 700 of the top surface, and is beneficial to the quick assembly and production of the battery swap station, and improves the production efficiency. In addition, the first connecting beam 507 and / or the second connecting beam 508 are connected with the protective plate 700 of the top surface through the first mounting portion, which can reinforce the protective plate 700 and the first connecting beam 507 and / or the second connecting beam 508, and is beneficial to improve the reliability of the cabinet.

[0175] As shown in Figure 1 and Figure 3 , since the battery swap station is provided with the intermediate battery swap area 900 between the two battery storage areas 800, a middle installation area 512 is also needed to be arranged between the two top units 501, and the temperature adjusting unit 513 is installed in the middle installation area 512, which is beneficial to reliably realize temperature adjustment and does not occupy the space of the battery storage area 800, and more space in the battery storage area 800 can be used for storing battery packs.

[0176] As shown in Figures 1-3 , Figures 4-9 , the bottom assembly 100 includes two support modules 20 at both ends, and the two support modules 20 correspond to the two battery charging rack assemblies 200, and the bottoms of the two battery charging rack assemblies 200 are respectively connected to the two support modules 20. Since the energy storage station only includes the battery storage area 800, only the connecting members need to be arranged on the two support modules 20 corresponding to the two battery storage areas 800 or the two battery charging rack assemblies 200 to be connected to each other.

[0177] The bottom structures of the two battery charging rack assemblies 200 are the same, and can be used interchangeably in the assembly process, without the need for comparison and matching in the assembly process, facilitating the assembly, thereby facilitating the improvement of the assembly efficiency of the box body.

[0178] As shown in FIG. 1, the battery swap station comprises a bottom assembly 100, a plurality of battery charging racks 200, a plurality of battery swap vehicles 300, and a plurality of battery swap vehicles 400. Figure 4 As shown in FIG. 1, the battery swap station comprises a bottom assembly 100, a plurality of battery charging racks 200, a plurality of battery swap vehicles 300, and a plurality of battery swap vehicles 400.

[0179] It should be noted that the battery swap vehicle is used to transfer the battery between the electric vehicle and the battery transfer device (such as a stacker crane or a lift), and the battery transfer device is used to transfer the battery between the charging rack 200 and the battery swap vehicle.

[0180] In an alternative embodiment, as shown in FIG. 2, the guide module 10 comprises at least two tracks extending in parallel along the first direction. Figures 4-7

[0183] In another alternative embodiment, the guide module 10 has a middle area between the two first cross beams 103 and / or the two first longitudinal beams 104, and the middle area is provided with a panel 106.

[0184] ​The middle region of the bottom assembly 100 is sealed by the panel 106 to prevent the influence of the external environment, such as rodents.

[0185] In addition, it should be noted that the panel 106 can be a whole plate or a plurality of sub-panels spliced together.

[0186] In another optional embodiment, the panel 106 of the middle region is provided with a foamed filler (not shown in the figure).

[0187] The foamed filler can further seal the panel 106 to prevent water, which is beneficial to improve safety and durability.

[0188] As shown in Figure 4 and Figure 10 In another optional embodiment, the two positioning modules 30 are respectively a front positioning module 301 located at the front side of the guide module 10 and a rear positioning module 302 located at the rear side of the guide module 10, the front positioning module 301 includes a front lifting platform 303 and a front lifting mechanism (not shown in the figure) located below the front lifting platform 303, and the front lifting mechanism is used to drive the front lifting platform 303 to lift; the rear positioning module 302 includes a rear lifting platform and a rear lifting mechanism located below the rear lifting platform, and the rear lifting mechanism is used to drive the rear lifting platform to lift. In one embodiment, the structures of the two positioning modules 30 are the same, Figure 10 The structure of the front positioning module 301 is shown schematically. The structures of the two positioning modules 30 can also be designed to be different according to actual needs.

[0189] Under the action of the lifting mechanism, the lifting platform can be lifted according to actual needs, so that the electric vehicle is lifted, which is beneficial to realize reliable battery replacement of the electric vehicle.

[0190] In another optional embodiment, it is understood with reference to Figure 4 and Figure 10 The front positioning module 301 further includes a first side front wheel alignment device and a second side front wheel alignment device provided on the front lifting platform 303, and / or the rear positioning module 302 further includes a first side rear wheel alignment device and a second side rear wheel alignment device provided on the rear lifting platform, and the first side front wheel alignment device, the second side front wheel alignment device, the first side rear wheel alignment device and the second side rear wheel alignment device are respectively installed on the first side front wheel alignment device reserved hole position 304, the second side front wheel alignment device reserved hole position 304, the first side rear wheel alignment device reserved hole position 304 and the second side rear wheel alignment device reserved hole position 304.

[0191] The first side front wheel positioning device, the first side rear wheel positioning device, the second side front wheel positioning device and the second side rear wheel positioning device can reliably position the front wheels and the rear wheels of the electric vehicle, thereby facilitating reliable battery replacement of the electric vehicle.

[0192] In another optional embodiment, the first side front wheel positioning device, the second side front wheel positioning device, and / or the first side rear wheel positioning device, the second side rear wheel positioning device are movably arranged on the front positioning module 301 and / or the rear positioning module 302 along the first direction and / or the second direction.

[0193] The movable front wheel positioning device and the rear wheel positioning device can adjust the distance between the corresponding positioning devices according to actual needs, thereby being applicable to different vehicle models and improving the application range of the bottom assembly 100.

[0194] It should be noted that the front wheel positioning device and the rear wheel positioning device can adopt any structure capable of positioning the wheels in the prior art, which will not be described here.

[0195] In another optional embodiment, as shown in Figure 6 The bottom assembly 100 further comprises at least one expansion module 40, which is detachably arranged between the guide module 10 and at least one positioning module 30. Among them, Figure 6 The splicing of the expansion module 40 and the guide module 10 is schematically shown.

[0196] When the expansion module 40 is arranged between the guide module 10 and the positioning module 30, the distance between the front wheel positioning device and the rear wheel positioning device can be increased, and the battery replacement of the electric vehicle with a longer length can be adapted. Therefore, by using the above structure, the battery replacement of different vehicle models can be adapted.

[0197] It should be noted that as an illustrative embodiment, when the expansion module 40 needs to be arranged, the connection between the guide module 10 and the positioning module 30 needs to be released, and then the expansion module 40 is installed between the positioning module 30 and the guide module 10.

[0198] In addition, it should be noted that according to actual needs, the expansion module 40 can be arranged between the positioning module 30 and the guide module 10 on one side, or the expansion module 40 can be arranged between the positioning module 30 and the guide module 10 on both sides, or multiple expansion modules 40 can be arranged between the positioning module 30 and the guide module 10 on one side.

[0199] In another optional embodiment, as shown in Figures 6-9As shown, the guide module 10 has multiple first positioning parts 107 at positions for splicing with the two support modules 20 and the two positioning modules 30, and corresponding positions on the two support modules 20 and the two positioning modules 30 have second positioning parts 201 adapted to the first positioning parts 107. The first positioning parts 107 and the second positioning parts 201 both serve as connectors to facilitate quick assembly and connection of the support modules 20 and the positioning modules 30.

[0200] Each module is equipped with a corresponding connector, making the assembly of the modules convenient and reliable.

[0201] Reference Figures 6-9 It is understood that the first positioning part 107 includes a first positioning plate 108, and the second positioning part 201 includes a second positioning plate 202 that cooperates with the first positioning plate 108. The first positioning plate 108 and the second positioning plate 202 are detachably connected by a flange. This arrangement facilitates quick and reliable assembly and disassembly.

[0202] Alternatively, the first positioning plate 108 is also provided with a guide block 109, and the second positioning plate 202 is provided with a positioning groove 203 that matches the guide block 109. The cooperation between the guide block 109 and the positioning groove 203 facilitates more accurate positioning.

[0203] It should be noted that the first positioning part 107 and the second positioning part 201 can be configured with any positioning structure applicable to this, depending on actual needs, and are not limited to the above-described structural form. For example, the configurations of the first positioning part 107 and the second positioning part 201 can be interchanged. Furthermore, the first positioning part 107 and the second positioning part 201 primarily function as a connection between the support module 20 and the positioning module 30. The guide block 109 and the positioning groove 203 are configured for quick alignment during connection to achieve a positioning function. When alignment accuracy is not required or cost-saving is desired, the first positioning part 107 and the second positioning part 201 can also simply be connecting components with a connecting function.

[0204] like Figures 4-6 As shown, the first track 101 extends at least partially into the support module 20. This allows the battery swapping trolley to work in conjunction with the battery transfer device in the battery storage area, facilitating fast and reliable battery swapping.

[0205] like Figure 4 , Figure 8 and Figure 9 As shown, the support module 20 is a frame structure, including at least two second crossbeams 204 extending along a first direction and at least two second longitudinal beams 205 extending along a second direction. A vertically arranged charging rack 200 is also provided on the frame structure. The support module 20 has a relatively simple structure, facilitating rapid prototyping and thus promoting the rapid construction of the battery swapping station.

[0206] As an illustrative embodiment, the support module 20 is configured by at least two second cross beams 204 extending in the first direction and at least two second longitudinal beams 205 extending in the second direction, wherein the second rails are respectively arranged on the second longitudinal beams 205. The support module 20 is simple in structure and facilitates rapid molding. The second rails are arranged on the second longitudinal beams 205 without occupying additional space for laying the second rails, which is conducive to reducing the space occupied by another guide module, and in turn is conducive to reducing the space occupied by the bottom assembly 100.

[0207] As shown in Figure 1 and Figure 3 , the ends of the top assembly 500 and the bottom assembly 100 respectively extend beyond the outer edges of the battery charging rack assembly 200. The box further comprises a plurality of support columns 300 connected between the top assembly 500 and the bottom assembly 100 at corresponding end positions of the top assembly 500 and the bottom assembly 100.

[0208] Among them, the support column 300 can further play a supporting role, facilitating the installation of the protective plate 700 outside the frame of the box. At the same time, with the above structure, the connection of the top assembly 500, the bottom assembly 100 and the corresponding battery charging rack assembly 200 can also be facilitated.

[0209] In another optional embodiment, the support column 300 is provided with at least one second mounting portion (not shown in the figure), which is arranged outward of the box and is used to connect the protective plate 700 on the side of the box.

[0210] Among them, the above structure can realize the rapid installation of the support column 300 and the side protective plate 700, which is conducive to rapid assembly and production and improves production efficiency. In addition, the connection of the support column 300 and the side protective plate 700 of the box through the second mounting portion can also reinforce the support column 300 and the side protective plate 700 of the box to a certain extent.

[0211] The box further comprises the above protective plate 700, which is installed on the top surface and / or the side surface of the box. The protective plate 700 installed on the top surface of the box is provided with at least one third mounting portion matched with the first mounting portion, and the protective plate 700 installed on the side surface of the box is provided with at least one fourth mounting portion matched with the second mounting portion.

[0212] Among them, through the cooperation of the first mounting portion and the third mounting portion, the protective plate 700 on the top surface of the box and the top unit 501 are quickly and reliably connected, and through the cooperation of the second mounting portion and the fourth mounting portion, the protective plate 700 and the side surface of the box are reliably connected. Accordingly, the whole box can also be reinforced.

[0213] It should be noted that the first mounting portion, the second mounting portion, the third mounting portion and the fourth mounting portion in the embodiment can be any mounting structure or connecting structure that can be applied thereto, as long as the connection between the corresponding two structural members can be achieved.

[0214] When the box is the box of the battery swap station, as shown in Figures 1-3 and Figure 11 , in another alternative embodiment, the top assembly 500 further comprises a middle mounting area 512 between the two top units 501, the middle mounting area 512 is arranged above the battery swap area 900 and is provided with a temperature regulating unit 513.

[0215] Among them, the temperature regulating unit 513 is arranged in the middle, which is convenient and reliable to regulate the temperature of the battery storage area 800 where the battery charging rack assembly 200 on both sides is located, which is beneficial to improve the energy utilization rate.

[0216] As shown in Figures 1-3 , Figures 4-10 , the bottom assembly 100 further comprises a guide module 10 arranged at the bottom of the battery swap area 900 and two positioning modules 30, the guide module 10 is used for the battery swap equipment to travel and is arranged between the two support modules 20, and the two positioning modules 30 are arranged at different sides of the guide module 10 and the two support modules 20. Among them, the guide module 10 and / or the positioning module 30 are provided with connecting pieces for connecting the guide module 10 between the two positioning modules 30, and the guide module 10 and / or the support module 20 are provided with connecting pieces for connecting the guide module 10 between the two support modules 20.

[0217] Among them, the bottom assembly 100 is assembled by the support module 20, the guide module 10 and the positioning module 30 through the connecting pieces, and the support module 20, the guide module 10 and the positioning module 30 can be formed at the same time, which is convenient for quick assembly and disassembly, and is beneficial to improve the assembly efficiency of the box and the battery swap station. At the same time, due to the independence of each module, when a part of the bottom assembly 100 fails or is damaged, only the corresponding damaged part needs to be replaced, for example, if one of the positioning modules 30 fails, only the failed positioning module 30 needs to be replaced, without the need to replace the entire bottom assembly 100 of the battery swap station, which is beneficial to reduce the overall construction cost.

[0218] The above-mentioned box can also be applied to the energy storage station, except that the energy storage station does not include the above-mentioned battery swap area 900.

[0219] In the present application, first, the battery swap station or energy storage station is formed by assembling the bottom assembly 100, the top assembly 500, and the battery charging rack assembly 200 into a box frame. When expansion is needed, the expansion box can be quickly extended and assembled along each expandable direction of the battery swap station or energy storage station, so that the battery capacity of the battery swap station or the storage space of the energy storage station can be conveniently and quickly expanded. At the same time, since the box frame does not block the electrical connection after expansion, the extension box is easy to power on, so that the battery swap station or energy storage station has high expandability.

[0220] Second, the box can be formed by separately molding the bottom assembly 100, the top assembly 500, and the battery charging rack assembly 200, and then connecting the battery charging rack assembly 200, the bottom assembly 100, and the top assembly 500. Since the bottom assembly 100, the top assembly 500, and the battery charging rack assembly 200 and other modules can be assembled simultaneously, the battery swap station or energy storage station can be quickly formed and has high construction efficiency. Since each module is assembled from each part, each part has a relatively small size, and each part can be pre-treated, such as by electrophoresis, so that the surface treatment effect of each part is better and the corrosion resistance of the battery swap station is improved.

[0221] Third, since the battery swap station or energy storage station containing the above box is assembled and formed, the space and position of the internal equipment and lines can be reserved according to actual needs when the battery swap station or energy storage station is built, which is beneficial to the reasonable layout of the internal structure and equipment of the battery swap station or energy storage station.

[0222] Fourth, since the box is only a frame structure, the protection plate 700 can be installed on the outside of the box to form the whole battery swap station or energy storage station. When the battery temperature is too high, the protection plate 700 can be directly removed or ejected from the inside to move the battery or internal contents out of the battery swap station, thereby improving the safety of the battery swap station or energy storage station.

[0223] Embodiment 2

[0224] The present embodiment discloses an assembly method of the battery swap station or energy storage station of the above embodiment 1. In the present embodiment, the same reference signs as in embodiment 1 refer to the same elements. As shown in the figure, Figure 14 The assembly method comprises the following steps:

[0227] Step S300: Assemble the top component 500 and install the top component 500 onto the top of the two battery charging rack components 200.

[0228] Firstly, the battery swapping station or energy storage station is formed by assembling a box frame consisting of a bottom component 100, a top component 500, and a battery charging rack component 200. When expansion is required, the expansion box can be quickly extended and assembled along various expansion directions of the battery swapping station or energy storage station, thereby conveniently and quickly expanding the battery capacity of the battery swapping station or the storage space of the energy storage station. At the same time, since the box frame is unobstructed, it facilitates electrical connections after expansion and makes it easy to power on the expansion box, thus the battery swapping station or energy storage station has high scalability.

[0229] Secondly, the enclosure can be constructed by first molding the bottom component 100, top component 500, and battery charging rack component 200 separately, and then connecting them. Since each module, including the bottom component 100, top component 500, and battery charging rack component 200, can be assembled simultaneously, the battery swapping station or energy storage station can be rapidly constructed with high efficiency. Furthermore, since each module is assembled from individual components, and these components are relatively small, their surfaces can be pre-treated, such as by electrophoresis, resulting in better surface treatment and improved corrosion resistance of the battery swapping station.

[0230] Third, since the battery swapping station or energy storage station containing the above-mentioned box is assembled, space and location for internal equipment and lines can be reserved according to actual needs during construction, which is conducive to the reasonable layout of the internal structure and equipment of the battery swapping station or energy storage station.

[0231] Fourth, since the enclosure is only a frame structure, a battery swapping station or energy storage station can be formed by installing a detachable protection plate 700 on the outside of the enclosure. When the battery temperature is too high, the battery or internal contents can be directly removed from the battery swapping station by removing or pushing out the protection plate 700 from the inside, thereby improving the safety of the battery swapping station or energy storage station.

[0232] In addition, the battery charging rack assembly 200 provides support. The assembly method of this battery swapping station or energy storage station is relatively simple.

[0277] The positioning module 30 is installed at the two ends of the guide module 10 in the front-rear direction.

[0278] Among them, the guide module 10 is separately formed and then assembled with other modules, which is beneficial to improve the assembly efficiency.

[0279] In another alternative embodiment, the guide module 10 includes a guide frame 102 composed of at least two second cross beams 204 extending in the front-rear direction and at least two second longitudinal beams 205 extending in the front-rear direction;

[0280] Assembling the guide module 10 comprises the steps of:

[0281] The second cross beam 204 and the second longitudinal beam 205 are assembled to form the guide frame 102;

[0282] At least one guide rail surface is provided on each of the two second cross beams 204 for the battery swap trolley to walk.

[0283] Among them, the guide module 10 has a simple structure and is easy to assemble quickly. The guide rail surface is convenient for walking and can also play a guiding role.

[0284] In another optional embodiment, the assembling guiding module 10 further comprises the steps of:

[0285] Laying the panel 106 in the middle region formed between the two second cross beams 204;

[0286] Foaming filling is performed in the middle region, and the foaming filling position is below the panel 106.

[0287] With the above structure, the sealing effect and strength can be improved.

[0288] In another optional embodiment, the positioning module 30 comprises a lifting platform, a lifting mechanism below the lifting platform, and a positioning mechanism on the lifting platform.

[0289] The positioning module 30 is installed at the front and rear ends of the guiding module 10, comprising the steps of:

[0290] The lifting mechanism is installed below the lifting platform.

[0291] The positioning mechanism is installed on the lifting platform.

[0292] The positioning module 30 is installed at the front and rear ends of the guiding module 10.

[0293] The positioning module 30 is convenient and efficient to assemble. The positioning module 30 is located at the front and rear ends of the guiding module 10, which is convenient for positioning the front and rear wheels of the vehicle.

[0294] In addition, it should be noted that in the present application, the assembly method of the battery swap station is mainly for the assembly of the box body of the battery swap station. As for other internal structures, including electric control devices, battery swap equipment, etc., the assembly method can be installed according to the existing technology.

[0295] In the present application, first, the battery swap station or energy storage station is formed by assembling the bottom assembly 100, the top assembly 500, and the battery charging rack assembly 200 to form a box frame. When expansion is needed, the expansion box can be quickly extended and assembled along each expandable direction of the battery swap station or energy storage station, so that the battery capacity of the battery swap station or the storage space of the energy storage station can be conveniently and quickly expanded. At the same time, since the box frame is not blocked and facilitates electrical connection after expansion, the expansion box is powered on, so that the expandability of the battery swap station or energy storage station is high.

[0296] Secondly, the box can be formed by first forming the bottom assembly 100, the top assembly 500 and the battery charging rack assembly 200 respectively, and then connecting the battery charging rack assembly 200, the bottom assembly 100 and the top assembly 500. Since the bottom assembly 100, the top assembly 500 and the battery charging rack assembly 200 and other modules can be assembled simultaneously, the battery swap station or the energy storage station can be quickly formed and has high construction efficiency. Moreover, each module is assembled by various parts, and the size of each part is relatively small. 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.

[0297] Thirdly, since the battery swap station or the energy storage station containing the box is assembled and formed, the space and position of internal equipment and lines can be reserved according to actual needs when the battery swap station or the energy storage station is built, which is beneficial to the reasonable arrangement of internal structures and equipment in the battery swap station or the energy storage station.

[0298] Fourthly, since the box is only a frame structure, the overall battery swap station or energy storage station can be formed by installing the detachable protective plate 700 on the outside of the box. When the temperature of the battery is too high, the battery or the internal contents can be directly removed from the battery swap station by directly removing or ejecting the protective plate 700 from the inside, thereby improving the safety of the battery swap station or the energy storage station.

[0299] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example. The protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and these changes and modifications all fall within the protection scope of the present application.
