Abstract

The present invention provides a bracket assembly and a battery swap station and energy storage station including the same. The bracket assembly includes at least one column unit, and the column unit includes at least two first columns arranged at intervals and at least two second columns arranged at intervals. A track and a connector are connected between two adjacent first columns. The track is used for the sliding of a battery transfer device. The connector is provided with a sliding portion for the sliding of the battery transfer device. The two adjacent first columns and the corresponding two second columns form a three-dimensional charging area for charging the battery pack. By directly arranging the track and the connector on the first column, the present invention saves the labor required to set up an area for placing the track on the container body, thereby speeding up the assembly speed of the battery swap station or energy storage station. Because the track and the connector are directly connected to the first column, the bracket assembly can be applied to a frame-structured battery swap station or energy storage station without a container body, thereby making the bracket assembly more widely applicable.

Description

Technical Field

[0001] The present invention relates to the field of battery replacement for electric vehicles, and in particular to a bracket assembly and a battery replacement station and an energy storage station comprising the bracket assembly. Background Art

[0002] In the prior art, the columns in the container-type battery swap station are connected to the container body, and the battery transfer device in the battery swap station is set in the space surrounded by the charging rack and the box body, such as Figure 1 As shown, the battery transport device 1' is a single-track operation, and its track 3' is respectively connected to the upper and lower parts of the box body, and has no direct connection with the charging rack 2'. The charging rack 2' does not participate in the sliding of the battery transport device 1'. When installing the track 3' of the battery transport device 1', it is necessary to set up an area on the box body for placing the track 3', which makes the installation of the track 3' take a long time and the assembly speed of the battery swap station is slow. Due to factors such as the setting position of the track 3', the structures of the track 3' and the charging rack 2' are different, and the two need to be produced separately, which is not conducive to the rapid production of the battery swap station. Summary of the Invention

[0068] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0069] Example 1

[0070] This embodiment provides a bracket assembly for a battery swap station and a battery swap station including the bracket assembly, such as Figure 2-4 As shown, the battery swap station is a frame-type station and includes a charging rack and a battery transfer device 1. The charging rack is used to store and charge battery packs, and the battery transfer device 1 is used to remove and store battery packs. The charging rack includes a bracket assembly, which includes two opposing column units 2. The two column units 2 form a track space 3 for the battery transfer device 1 to slide.

[0071] In other alternative embodiments, depending on the size and layout of the battery swap station, more than two column units 2 may be provided. To improve space utilization and reduce the time and energy consumed by the battery transporter 1 in removing the battery pack, it is preferred that any column unit 2 has another column unit 2 opposite it, with a track space 3 formed between two adjacent column units 2 for the sliding of the battery transporter 1. Furthermore, the number of column units 2 may be only one.

[0072] The column unit 2 includes a plurality of first columns 21 and a plurality of second columns 22 spaced apart. The spacing direction of the second columns 22 is parallel to the spacing direction of the first columns 21 and corresponds one-to-one with the first columns 21. The first columns 21 are located on the side close to the track space 3, and the second columns 22 are located on the side away from the track space 3. A track 23 and a connector 24 are connected between two adjacent first columns 21. The track 23 is located at the bottom of the first column 21 and is used for the sliding of the battery transfer device 1 in the battery swap station. The connector 24 is located at the top of the first column 21. The track 23 extends along the spacing direction of the first columns 21. The connector 24 is parallel to the track 23. The connector 24 is provided with a sliding portion 241 for the sliding of the battery transfer device 1. The two adjacent first columns 21 and the corresponding two second columns 22 form a three-dimensional charging area 4 for charging the battery pack.

[0073] The track 23 and the connector 24 are directly arranged on the first column 21. Therefore, there is no need to set up an area for placing the track 23 and the connector 24 on the container body as in the prior art. This saves the man-hours required to set up an area for placing the track 23 on the body, and speeds up the assembly of the battery swap station. Moreover, because the track 23 and the connector 24 are directly connected to the first column 21, the bracket assembly can be applied to frame-structured battery swap stations without a container body, thereby making the bracket assembly more applicable. Moreover, part of the force exerted on the track 23 and the connector 24 can be shared by the first column 21, thereby enhancing the sliding reliability of the battery transfer device 1. The bracket assembly integrates the functions of the charging rack and the battery transfer device track, and can be used for modular assembly of battery swap stations.

[0074] It should be noted that the number and spacing of the first and second columns 21, 22 in the column unit 2 can be adjusted based on actual needs. However, to ensure the stability of the three-dimensional charging area 4 and the normal sliding of the battery transporter 1, the number of first and second columns 21, 22 should be at least two. When the number of column units 2 in the bracket assembly is only one, the track 23 and connector 24 are subjected to greater forces. To ensure the stability of the bracket assembly during use, it is necessary to strengthen the fixing strength between the track 23 and connector 24 and the first column 21.

[0075] The battery swap station also includes a base 5 for placing the bracket assembly, and the bottoms of the first column 21 and the second column 22 are connected to the base 5. The track 23 is provided on the side of the first column 21 and on the outside of the three-dimensional charging area 4. The lower end surface of the track 23 is flush with the lower end surface of the first column 21, so the track 23 and the first column 21 can be placed on the same plane, which is equivalent to the track 23 being directly placed on the base 5. Part of the force exerted on the track 23 can also be shared by the base 5. The track 23 can play a certain supporting role in the overall frame structure of the battery swap station, and can also reduce the fixing strength between the track 23 and the first column 21 to a certain extent, saving time and cost.

[0076] In other alternative embodiments, when the track 23 is provided on the side of the first column 21, the lower end surface of the track 23 may not be flush with the lower end surface of the first column 21, and the lower end surface of the track 23 may be located above or below the lower end surface of the first column 21. When the lower end surface of the track 23 is located above the lower end surface of the first column 21, in order to ensure the stability of the bracket assembly during use, the fixing strength between the track 23 and the first column 21 should be strengthened; when the lower end surface of the track 23 is located below the lower end surface of the column, in order to ensure the stability of the bracket assembly during placement, other components should be added to the lower end surface of the bracket assembly, such as a bottom beam structure connecting two adjacent first columns 21, and the lower end surface of the added component can be flush with the lower end surface of the track 23. In addition, the track 23 can also be provided below the first column 21, in which case the upper end surface of the track 23 is connected to the lower end surface of the first column 21.

[0077] The connector 24 is provided on the side of the first column 21 and on the outside of the three-dimensional charging area 4. The upper end surface of the connector 24 is flush with the upper end surface of the first column 21. The battery swap station also includes an upper plate 6 covering the connector 24, the first column 21 and the second column 22. The upper plate 6 can enhance the stability of the bracket assembly and can prevent rain, snow, dust and other substances from entering the interior of the battery swap station. The upper end surface of the connector 24 is flush with the upper end surface of the first column 21, so the upper plate 6 can be made into a simple flat plate structure. The total contact area between the upper plate 6 and the connector 24, the first column 21 and the second column 22 is larger, and the bracket assembly can better support the upper plate 6. The connector 24 can also play a role in strengthening the strength of the frame structure battery swap station to a certain extent.

[0078] In other alternative embodiments, when the connector 24 is provided on the side of the first column 21, the upper end surface of the connector 24 may not be flush with the upper end surface of the first column 21, and the upper end surface of the connector 24 may be located above or below the upper end surface of the first column 21. When the upper end surface of the connector 24 is below the upper end surface of the first column 21, it should be ensured that the battery transport device 1 can obtain the battery placed on the top of the charging rack during the battery replacement process; when the upper end surface of the connector 24 is above the upper end surface of the first column 21, in order to ensure the stability of the upper plate 6 placed above the bracket assembly, other components should be added to the upper end surface of the bracket assembly, such as a top beam structure connecting two adjacent first columns 21, and the upper end surface of the added component can be flush with the upper end surface of the connector 24. In addition, the connector 24 can also be provided above the first column 21, in which case the lower end surface of the connector 24 is connected to the upper end surface of the first column 21.

[0079] In order to facilitate the sliding of the battery transfer device 1, a sliding groove or guide rail or other structures that facilitate sliding can be set on the side of the connecting member 24 to form a sliding part on the connecting member 24. The sliding groove or guide rail can effectively reduce the friction resistance generated during sliding, reduce energy consumption, and reduce material wear.

[0080] Both the track 23 and the connector 24 are detachably connected to the first column 21. Therefore, during transportation, the entire column unit 2 can be disassembled and shipped, thereby reducing freight resources and lowering freight costs. The detachable connection method can be any connection method known to those skilled in the art, such as threaded connections, snap connections, rivet connections, and plug-in connections. In other alternative embodiments, the track 23 and the first column 21, as well as the connector 24 and the first column 21, can be fixedly connected or even integrally formed.

[0081] The bracket assembly can be made of common aluminum profiles. The structural shape of the aluminum profile allows for quick assembly of the first column 21, rail 23, and connector 24 within the bracket assembly, making installation more convenient and significantly reducing assembly time. Furthermore, aluminum profiles are low-cost and environmentally friendly, meeting environmental requirements while reducing costs. The use of aluminum profiles throughout the bracket assembly also enhances the overall appearance.

[0082] In other alternative embodiments, the bracket assembly can be made of other structures or materials, and the first column 21, second column 22, track 23, and connector 24 in the bracket assembly can be made of different structures or materials. However, it should be ensured that the selected structure or material can meet the strength requirements of the battery swap station and the connection strength between the first column 21, track 23, and connector 24. In addition, the selected structure and material need to be easy to splice, thereby reducing the time required to connect the first column 21, track 23, and connector 24 in the bracket assembly, and speeding up the assembly time of the battery swap station.

[0083] The first and second columns 21, 22 are provided with a plurality of mounting members 25, which are arranged along the height of the bracket assembly. The mounting members 25 are used to mount the battery charging tray, facilitating quick assembly of the battery charging tray with the first and second columns 21, 22. The identical structure of the first and second columns 21, 22 reduces production costs associated with different structures and speeds up assembly of the battery swap station.

[0084] The specific structure of the mounting member 25 is not specifically discussed in this embodiment. The mounting member 25 can be a hook structure. In this case, a hanging hole that matches the hook is provided on the battery charging tray to facilitate the rapid assembly between the first column 21, the second column 22 and the battery charging tray. The mounting member 25 can also be a threaded hole. In this case, a matching threaded hole is provided on the battery charging tray, and the first column 21, the second column 22 are threadedly connected to the battery charging tray. The structure of the mounting member 25 should facilitate the subsequent maintenance after the rapid assembly between the first column 21, the second column 22 and the battery charging tray, which is conducive to the modular assembly of the battery swap station and improves assembly efficiency. The mounting member 25 can be formed by drilling a hole on the first column 21 or the second column 22, or the mounting member 25 can be fixed to the first column 21 or the second column 22 by welding or a detachable connection. The mounting member 25 can also be integrally formed with the first column 21 or the second column 22. In other alternative embodiments, the battery charging tray may be mounted on the first column 21 and the second column 22 in different fixing ways, and is not limited to being provided with multiple mounting members 25 on the first column 21 and the second column 22 at the same time.

[0085] The two sides of the track space 3 are three-dimensional charging areas 4. The track 23, connector 24 and battery loading device are all accommodated in the track space 3. The battery transfer device 1 slides in the track space 3 to obtain the battery packs in the three-dimensional charging areas 4 on both sides.

[0086] The battery transporter 1 is mounted on a track 23 and slides within the track space 3 via the sliding portions on the track 23 and the connector 24. Both the track 23 and the connector 24 guide the sliding of the battery transporter 1. The track 23 primarily limits the sliding direction of the battery transporter 1, while the connector 24 prevents deviation in the sliding direction of the battery transporter 1.

[0087] like Figure 4-5 As shown, the battery transport device 1 adopts a double-gantry structure, with two gantries 11 respectively arranged on both sides of the battery transport device 1 near the two column units 2. The battery transport device 1 also includes a first sliding member 12 that cooperates with the track 23 and a second sliding member 13 that cooperates with the connector 24. The first sliding member 12 cooperates with the side of the track 23, and the second sliding member 13 cooperates with the sliding portion of the connector 24, so that the battery transport device 1 can slide within the track space 3 via the sliding portion on the track 23 and the connector 24. The battery transport device 1 is placed on the track 23, which supports the battery transport device 1, so the track 23 is subjected to a large force. The track 23 is connected to the first column 21 and is placed on the base 5, so that the force applied to the track 23 can be shared by the first column 21 and the base 5, thereby enhancing the sliding reliability of the battery transport device 1.

[0088] The track 23 is a common guide rail or slide groove structure, and the first sliding member 12 is a slider or sliding ball that matches the structure of the track 23. The sliding portion of the connecting member 24 is a smooth surface, and the second sliding member 13 is a slider structure that can fit the sliding portion of the connecting member 24. The friction between the two ensures that the connecting member 24 guides the battery transport device 1. In other alternative embodiments, in order to make the second sliding member 13 slide more smoothly relative to the connecting member 24, the second sliding member 13 can also be designed as a sliding ball structure. In order to strengthen the connection between the second sliding member 13 and the connecting member 24, the connecting member 24 can be designed as a guide rail or slide groove structure that matches the second sliding member 13, and the second sliding member 13 can also be designed as a slot structure for matching the connecting member 24.

[0089] It should be noted that, in this embodiment, the battery transfer device 1 adopts a double-gantry structure, but in other alternative implementations, the battery transfer device 1 may also adopt a single-gantry structure, but it should be ensured that the battery transfer device 1 can operate smoothly and select battery packs normally.

[0090] In order to further enhance the strength of the battery swap station, the station also includes a crossbeam and longitudinal beam structure located at the top of the bracket assembly near the upper plate 6. The crossbeam connects the corresponding first columns 21 and second columns 22, and the longitudinal beam connects a plurality of spaced first columns 21 or a plurality of spaced second columns 22. The crossbeam and longitudinal beam are preferably detachably connected to the first and second columns 21 and 22, so that the position, layout, and number of the reinforcing beams can be adjusted according to actual needs, thereby increasing flexibility. In other alternative embodiments, if the required strength of the battery swap station is low, the crossbeam and longitudinal beam structure may not be provided, or only crossbeams or longitudinal beams may be provided.

[0091] The battery swap station also includes a position marker on the track 23. The position marker is used to identify the position of the battery transporter 1 relative to the track 23. The battery transporter 1 is equipped with a detection device to detect the position marker, allowing the battery transporter 1 to quickly and accurately slide to the corresponding position of the required battery pack, thereby speeding up the battery swap time. The position marker can be a reflector, radio frequency identification tag, or other structure that can achieve position identification.

[0092] In other alternative embodiments, the above-mentioned bracket assembly, battery transfer device, cross beam, longitudinal beam and position marker are not limited to use only in battery swap stations for electric vehicles, but can also be used in energy storage stations. The energy storage station is mainly used to charge battery packs with insufficient power to achieve the purpose of storing energy for the battery packs, but the energy storage station does not have the function of battery swapping.

[0093] Example 2

[0094] The structure of this embodiment is basically the same as that of the first embodiment, except that the number and position layout of the rails 23 and the connectors 24 are different.

[0095] like Figure 6 As shown, in this embodiment, in addition to the rails 23 and connectors 24 provided on the side of the first column 21 as in embodiment 1, the rails 23 and connectors 24 same as in embodiment 1 are also provided on the side of the second column 22.

[0096] A track 23 and a connector 24 are also connected between two adjacent second columns 22. The track 23 is located at the bottom of the second column 22, and the connector 24 is located at the top of the second column 22. The track 23 and the connector 24 are both located on the side of the second column 22 and outside the three-dimensional charging area 4. The lower end surface of the track 23 connected to the second column 22 is flush with the lower end surface of the second column 22, and the upper end surface of the connector 24 connected to the second column 22 is flush with the upper end surface of the second column 22.

[0097] Track spaces 3 for the sliding of the battery transfer device 1 are set on both sides of the three-dimensional charging area 4, which enables the battery swap station to replace battery packs for at least two electric vehicles at the same time, reducing the waiting time of users and improving the user experience.

[0098] The track 23 is arranged on the side of the second column 22 and on the outside of the three-dimensional charging area 4. The lower end surface of the track 23 is flush with the lower end surface of the second column 22. Therefore, the track 23 and the second column 22 can be placed on the same plane, which is equivalent to the track 23 being directly placed on the base 5. Part of the force exerted on the track 23 can also be shared by the base 5. The track 23 can play a certain supporting role in the overall frame structure of the battery swap station, and can also reduce the fixing strength between the track 23 and the second column 22 to a certain extent, saving labor time and cost.

[0099] In other alternative embodiments, when the track 23 is provided on the side of the second column 22, the lower end surface of the track 23 may not be flush with the lower end surface of the second column 22, and the lower end surface of the track 23 may be located above or below the lower end surface of the second column 22.
