[0031] The following is for reference. Figures 1-3 A modular battery swapping station 100 according to an embodiment of the present invention is described.

[0032] like Figures 1-3 As shown, the modular battery swapping station 100 according to an embodiment of the present invention includes a bottom module 1, a side wall module 2, and a top module 3.

[0033] Specifically, the bottom module 1 is used to store and charge the batteries. The top of the bottom module 1 may have multiple workstations 111 for placing the batteries. When a battery is placed on a workstation 111, it can be charged. Additionally, the bottom module 1 is equipped with positioning structures, each corresponding to one of the workstations 111. These positioning structures are used to position the batteries on their respective workstations 111, facilitating placement and improving the reliability of battery positioning.

[0034] In addition, multiple workstations 111 can be arranged in multiple rows and columns, with multiple rows along the width of the bottom module 1 (e.g., Figure 1 The columns are spaced apart along the W direction, with multiple columns along the length of the bottom module 1 (e.g., ...). Figure 1The multiple battery workstations 111 are spaced apart in the V direction (as shown), which facilitates the arrangement of multiple battery workstations 111 on the bottom module 1. Preferably, the multiple workstations 111 are arranged in two rows and multiple columns on the bottom module 1 to avoid the bottom module 1 being too wide and to facilitate the transportation of the bottom module 1.

[0035] For example, in Figure 3 In the example shown, multiple battery placement stations 111 are arranged in a two-row, three-column configuration. The two rows are spaced apart along the width of the bottom module 1, and the three columns are spaced apart along the length of the bottom module 1. However, this invention is not limited to this; the battery placement stations 111 can have more columns, such as two, four, five, or six columns. When the battery placement stations 111 are arranged in six columns and two rows, there are 12 battery placement stations 111.

[0036] Side wall modules 2 are located above bottom module 1. Multiple side wall modules 2 are spaced apart along the circumference of bottom module 1. The lower end of each side wall module 2 is detachably connected to bottom module 1. Two side wall modules 2 that are joined together are also detachably connected. The side wall modules 2 provide circumferential protection, safeguarding the battery on bottom module 1. Top module 3 is located above side wall modules 2. Top module 3 is detachably connected to the upper end of the multiple side wall modules 2. The top module 3, side wall modules 2, and bottom module 1 define an operating space 4. Together, these components define a relatively enclosed space, protecting the internal battery.

[0037] In this invention, the bottom module 1 and the side wall module 2 are detachably connected, the side wall module 2 and the top module 3 are detachably connected, and the two interconnected side wall modules 2 are detachably connected. During transportation and painting, the bottom module 1, the side wall module 2 and the top module 3 can be disassembled into multiple modules for painting and transportation. After the painting is completed and the transportation is completed to the designated location, the bottom module 1, the side wall module 2 and the top module 3 are assembled, which facilitates transportation and painting and reduces costs.

[0038] In addition, the bottom module 1, side wall module 2 and top module 3 are pre-assembled as a whole, that is, the bottom module 1, side wall module 2 and top module 3 are pre-assembled as a whole, which facilitates transportation and painting, reduces the number of parts, facilitates assembly, and improves assembly efficiency.

[0039] According to the modular battery swapping station 100 of this utility model embodiment, by making the bottom module 1 detachably connected to the side wall module 2, the side wall module 2 detachably connected to the top module 3, and the two side wall modules 2 connected to each other detachably connected, the modular battery swapping station 100 can be divided into multiple modules, which facilitates transportation and painting operations and reduces costs.

[0040] In some embodiments of this utility model, the bottom module 1 includes a support platform 11 and support legs 12. The support platform 11 is used to store batteries and charge them, facilitating battery placement and charging. The support platform 11 may have multiple workstations 111 for placing batteries, and a positioning structure is provided on the support platform 11. Additionally, the support platform 11 is also equipped with a charging device for charging the batteries.

[0041] Support legs 12 are located below and connected to the support platform 11. Multiple support legs 12 are spaced apart and have folded and unfolded states. In the unfolded state, the support legs 12 extend vertically. In the folded state, the end of the support leg 12 facing away from the support platform 11 is flush with the platform 11. In the unfolded state, the support legs 12 extend vertically, with the lower end supporting the ground and the upper end connected to the support platform 11 for support. In the folded state, the lower end of the support leg 12 can move upwards to flush with the lower surface of the support platform 11, reducing the space occupied by the bottom module 1 and facilitating its transport.

[0042] In some specific examples, one end of the support leg 12 is rotatably connected to the support platform 11, and the support leg 12 can rotate between an unfolded state and a folded state. For example, the upper end of the support leg 12 is rotatably connected to the support platform 11, and the lower end of the support leg 12 rotates about the rotation axis of the upper end of the support leg 12.

[0043] In addition, a locking mechanism may be provided on the bottom module 1. The locking mechanism is used to lock the support leg 12 in the unfolded state and in the folded state to prevent the support leg 12 from moving in the unfolded state, thereby improving the reliability of the support for the bearing platform 11. At the same time, it prevents the support leg 12 from unfolding in the folded state, which facilitates the transportation of the bottom module 1.

[0044] Furthermore, the bottom module 1 may also be provided with a first limiting structure and a second limiting structure. The support leg 12 rotates between the first limiting structure and the second limiting structure. When the support leg 12 is in the unfolded state, the support leg 12 abuts against the first limiting structure. When the support leg 12 is in the folded state, the support leg 12 abuts against the second limiting structure. This can better limit the rotation angle of the support leg 12 and prevent the rotation angle of the support leg 12 from being too large or too small, making it easier for the support leg 12 to switch between the unfolded state and the folded state.

[0045] In some embodiments of this utility model, multiple support legs 12 are arranged in multiple rows and columns. For example, in Figure 1 and Figure 2In the example shown, the support legs 12 are arranged in multiple rows spaced apart along the width direction of the bottom module 1 and multiple columns spaced apart along the length direction of the bottom module 1, specifically two rows and four columns, which can improve the support effect on the bearing platform 11.

[0046] In some embodiments of this utility model, the sidewall module 2 has a flat plate structure. Figures 1-3 In the example shown, the support platform 11 of the bottom module 1 is a rectangular structure, and at least four side wall modules 2 are provided on the four sides of the support platform 11. Figure 3 In the example shown, the long side of the support platform 11 is provided with three side wall modules 2 arranged along the length of the support platform 11, which can further reduce the overall volume of the side wall modules 2, making it easier to transport and paint.

[0047] In some embodiments of this utility model, such as Figures 1-3 As shown, the side wall module 2 includes a reinforcing frame 21 and a protective plate 22. The reinforcing frame 21 is detachably connected to the bottom module 1 and the top module 3. The reinforcing frame 21 has a first hollow area 211, and the protective plate 22 is disposed in the first hollow area 211 to seal it. The reinforcing frame 21 mainly serves as a connector and support, and can improve the structural strength of the entire side wall module 2. The protective plate 22 is connected to the reinforcing frame 21 and serves as a side protection.

[0048] Optionally, multiple first hollow areas 211 are spaced apart. This avoids the first hollow area 211 being too large, which would reduce the structural strength of the side wall module 2. The multiple first hollow areas 211 can be arranged along the circumferential direction of the bottom module 1.

[0049] Furthermore, the connection structure between the reinforcing frame 21 and the bottom module 1 and the top module 3 is located on the side of the protective plate 22 facing the operating space 4. This allows the structure connecting the reinforcing frame 21 to the bottom module 1 and the structure connecting it to the top module 3 to be hidden inside the protective plate 22, avoiding exposure and improving the flatness of the modular heat exchanger's appearance.

[0050] In some embodiments of this utility model, a sealing element is provided between the protective plate 22 and the reinforcing frame 21, thereby improving the sealing performance between the protective plate 22 and the reinforcing frame 21 and preventing rainwater, dust, etc. from entering the operating space 4 through the gap between the protective plate 22 and the reinforcing frame 21 and affecting battery charging.

[0051] Optionally, the protective plate 22 and the reinforcing frame 21 can be welded together or connected by fasteners.

[0052] In some embodiments of this invention, at least one sidewall module 2 has an opening 23 communicating with the operating space 4, or an opening 23 communicating with the operating space 4 is defined between two adjacent sidewall modules 2. The opening is used for storing the battery on the bottom module 1 for charging and for removing the charged battery and installing it on the vehicle. For example, the protective plate 22 of one of the first hollow areas 211 can be removed to form the opening 23, or the two sidewall modules 2 can be spaced apart to form the opening 23.

[0053] In some embodiments of this utility model, such as Figures 1-3 As shown, there is a first hollow area 211 without a protective plate in a side wall module 2. This area forms an entrance and exit, and there is a switch door at the entrance and exit. Operators can enter the operating space through the entrance and exit to observe and monitor.

[0054] In some embodiments of this utility model, the top module 3 integrates at least one of a control unit, a battery replacement mechanism, a lighting device, and a monitoring device. The control unit can control the battery replacement mechanism, the lighting device, the monitoring device, and the charging equipment on the bottom module 1; the battery replacement mechanism is used to replace the battery, unloading the battery from the vehicle and placing it into the empty battery bay 111 of the bottom module 1, and placing the charged battery into the vehicle; the lighting device is used to illuminate the operating space 4, and the monitoring device can be used to monitor the charging status of each battery and whether a battery is installed in bay 111.

[0055] Optionally, the battery replacement mechanism can be a robot. A track extending along the length of the bottom module 1 can also be provided above the top module 3. The track can be inserted into the opening 23, and the robot can move along the track, making it easier for the robot to move into or out of the operating space 4 through the opening 23, which makes on-site installation more convenient.

[0056] In some embodiments of this utility model, such as Figures 1-3 As shown, the top module 3 includes a top frame 31 and a top plate 32. The top frame 31 is detachably connected to the side wall module 2. The top frame 31 has multiple second hollow areas 311, and there are multiple top plates 32, each located within one of the multiple second hollow areas 311. The top frame 31 mainly serves as a connector and support, and can improve the structural strength of the entire top module 3. The top plates 32 are connected to the top frame 31 and serve as top protection.

[0057] Optionally, the top plate 32 can be a flat plate or a corrugated plate. When multiple top plates 32 are provided in the top module 3, the area of ​​a single top plate 32 can be relatively reduced, the structural strength requirements of the top plate 32 are reduced, and the top plate 32 can be a flat plate or a corrugated plate, which improves the selectivity of the top plate 32.

[0058] In some embodiments of this utility model, such as Figures 1-3 As shown, one end of the top module 3 extends beyond the side wall module 2 and the bottom module 1 in the longitudinal direction to form an extension end. The module swapping station also includes an isolated wall module 5. The lower end of the isolated wall module 5 and the bottom module 1 can be supported on the same plane. The isolated wall module 5 and the bottom module 1 are spaced apart. The upper end of the isolated wall module 5 is detachably connected to the extension end. A passage 6 for vehicle passage is defined between the isolated wall module 5, the bottom module 1, the side wall module 2 near the isolated wall module 5, and the top module 3. The opening 23 can be provided on the side wall module 2 that forms the passage 6, and the opening 23 can face the isolated wall module 5.

[0059] When the vehicle battery is being replaced, the vehicle can be driven into the channel 6. The battery replacement mechanism on the top module 3 can remove the battery from the vehicle and move it into the operating space 4, and place it on the work station 111 of the bottom module 1 for charging. The fully charged battery on the work station 111 is then moved out of the operating space 4 and installed on the vehicle. After the battery replacement is completed, the vehicle can be driven out from the other side of the channel 6.

[0060] In some embodiments of this utility model, such as Figures 1-3 As shown, the isolated wall module 5 includes an isolated wall frame 51 and isolated wall legs 52. The upper end of the isolated wall frame 51 is detachably connected to the top module 3, and the isolated wall legs 52 are connected to the lower part of the isolated wall frame 51 and are suitable for supporting the ground. Multiple isolated wall legs 52 can be spaced apart. The isolated wall frame 51 may have a third open area 511, and an isolated wall panel 512 may be installed within the third open area 511.

[0061] Optionally, the wall panel 512 and the wall frame 51 can be welded together or connected by fasteners. There is a seal between the wall panel 512 and the wall frame 51, thereby achieving a seal between the wall panel 512 and the wall frame 51 and preventing rainwater, dust and other substances from entering the channel 6 through the gap between the wall panel 512 and the wall frame 51.

[0062] In some embodiments of this utility model, the isolated wall support leg 52 may also have an unfolded state and a folded state. The upper end of the isolated wall support leg 52 may be rotatably connected to the isolated wall frame 51. The isolated wall frame 51 may be provided with a locking device for locking the isolated wall support leg 52.

[0063] In some embodiments of this invention, the area of ​​the top frame 31 of the top module 3 opposite to the channel 6 has an opening 312, which is used to hoist a battery replacement mechanism, such as a robot. Additionally, a cover plate is provided at the opening 312 to seal it.
