[0058] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0059] See Figure 1 and Figure 2This utility model provides a charging and battery swapping station 100. The charging and battery swapping station 100 includes a housing 111, battery racks, a palletizer 150, and a battery swapping robot 130. The housing 111 has standard container dimensions. A battery swapping channel 111e is provided in the housing 111. The battery swapping channel 111e extends through the housing 111 along its width direction D2 and is located at the end of the housing 111 in its length direction D1. The housing 111 also has an internal receiving space 111f. The receiving space 111f is adjacent to and communicates with the battery swapping channel 111e along the length direction D1 of the housing 111. The battery racks are disposed within the receiving space 111f. The battery racks include a first battery rack 140 and a second battery rack 160. The first battery rack 140 and the second battery rack 160 are spaced apart along the length direction D1 of the housing. The first battery rack 140 is located near the battery swapping channel 111e. The palletizer 150 is positioned between the first battery rack 140 and the second battery rack 160. The battery swapping robot 130 is located inside the housing 111. The battery swapping robot 130 is movable along the length D1 of the housing 111 between the battery swapping channel 111e and the accommodating space 111f.

[0060] The charging and battery swapping station 100 provided in this embodiment adopts a container with standard shipping container dimensions, which reduces the volume of the container, minimizes the floor space, and meets the requirements of maritime transport. The first battery rack, the second battery rack, and the palletizer are arranged along the length of the container's accommodating space 111f, improving the compactness of the internal structure. Simultaneously, the battery swapping robot can move along the length of the container between the battery swapping channel and the accommodating space 111f to transfer the vehicle battery 10 along the length direction. By employing the above-mentioned technical means, the volume of the charging and battery swapping station can be reduced, thereby lowering costs related to transportation, construction, and investment.

[0061] Continue reading Figure 1 and Figure 2 Optionally, the container 111 adopts the structure of a standard shipping container. The container 111 includes a base frame 111a, side walls 111b, a top cover 111c, and a door 111d. The base frame 111a is located at the bottom of the container 111 in the height direction D3. The side walls 111b are located on the sides of the container 111 in the width direction D2. The top cover 111c is located at the top of the container 111 in the height direction D3. The door 111d is located at the end of the container 111 in the length direction D1. In one example, doors 111d are provided at both ends of the container 111 in the length direction D1, which facilitates the transfer of battery racks, palletizers 150, and other facilities into the container 111, as well as extensive maintenance operations.

[0062] Continue reading Figure 1 and Figure 2 In some embodiments, the battery swapping robot 130 includes a support platform 131 for carrying the vehicle battery 10. The support platform 131 is rotatable between a first angular position parallel to the length direction D1 of the housing 111 and a second angular position parallel to the width direction D2 of the housing 111. When the battery swapping robot 130 is located in the battery swapping channel 111e and under the vehicle, the support platform 131 rotates to the second angular position. When the battery swapping robot 130 is located in the receiving space 111f and in the movement path between the receiving space 111f and the battery swapping channel 111e, the support platform 131 rotates to the first angular position. The first and second angular positions are two positions of the support platform 131 during rotation, illustrating that the support platform 131 can change its orientation by rotation to adapt to the installation and removal of the vehicle battery 10 and the charging needs of the vehicle battery 10, respectively. The support platform 131 rotating to the first angular position can be understood as the length direction of the support platform 131 being parallel to the length direction D1 of the housing 111. Correspondingly, the support platform 131 rotates to the second angle position, which can be understood as the length direction of the support platform 131 being parallel to the width direction D2 of the box 111.

[0063] See also Figure 1 and Figure 2 Optionally, the battery swapping robot 130 is configured such that the carrying platform 131 can rotate about a rotation axis AX parallel to the height direction D3, so as to achieve rotation to a first angular position and a second angular position.

[0064] The container 111 has standard container dimensions, facilitating the containerized transport of the charging and battery swapping station 100. In this embodiment, the container 111 can be a 40-foot standard container (length × width × height: 12192mm x 2438mm x 2896mm). Since the width of the container 111 is relatively short, and the length of the vehicle battery 10 is often greater than the width of the container, a reversal is required using the battery swapping robot 130 (the vehicle battery 10 rotates from being parallel to the width direction D2 of the container 111 in its length direction to being parallel to the length direction D1 of the container 111) before it can be moved from the battery swapping channel 111e into the receiving space 111f (or from the receiving space 111f into the battery swapping channel 111e). This achieves a compact structure, convenient transport, and functional integration suitable for battery swapping for the charging and battery swapping station 100.

[0065] See also Figure 1 and Figure 2In some embodiments, the first battery rack 140 includes a buffer layer 141 and a first charging layer 142. Along the height direction D3 of the housing 111, the buffer layer 141 is located at the bottom of the first battery rack 140. The buffer layer 141 communicates with the battery swapping channel 111e. A battery swapping robot 130 is movably disposed between the battery swapping channel 111e and the buffer layer 141 to transfer vehicle batteries 10 between a vehicle located in the battery swapping channel 111e and the buffer layer 141 of the first battery rack 140. Along the height direction D3 of the housing 111, the first charging layer 142 is located above the buffer layer 141. The buffer layer 141 is used to temporarily store vehicle batteries 10 in a depleted state or a fully charged state. Vehicle batteries 10 in a depleted state are removed from the vehicle and transferred by the battery swapping robot 130, and will be transferred to the first charging layer 142 by the palletizer 150. Vehicle batteries 10 in a fully charged state are transferred from the first charging layer 142 by the palletizer 150. The buffer layer 141 is located below the first charging layer 142, which facilitates docking with the battery swapping robot 130. The height of the buffer layer 141 within the accommodating space 111f is only required to be within the range of the lifting capacity of the support platform 131 of the battery swapping robot 130.

[0066] See Figure 2 Optionally, the charging and battery swapping station 100 also includes a battery swapping track 114. The battery swapping track 114 extends along the length direction D1 of the housing 111 and is laid inside the housing 111. Specifically, the battery swapping track 114 can be laid between the bottom of the battery swapping channel 111e and the bottom of the first battery rack 140. The battery swapping robot 130 is connected to the battery swapping track 114 and is able to move along the battery swapping track 114.

[0067] See Figure 1 and Figure 2 In some embodiments, the palletizer 150 includes forks 152. Along the length direction D1 of the housing 111, the forks 152 are retractable in the direction toward the first battery rack 140 and the direction toward the second battery rack 160, respectively. The forks 152 are also movable along the height direction D3 of the housing 111. Here, the forks 152 can be understood as bidirectional telescopic forks. The forks 152 are mounted on the rack 151 of the palletizer 150 and are able to rise and fall with the rack 151, thereby changing their position in the height direction D3 between a position aligned with the buffer layer 141 and a position aligned with the first charging layer 142.

[0068] Optionally, the buffer layer 141 and the first charging layer 142 are each provided with a support structure for supporting the vehicle battery 10. In an application scenario where the battery swapping robot 130 picks up and places the vehicle battery 10 in the buffer layer 141 using a lifting motion, the support structure in the buffer layer 141 can move between a position that avoids the vehicle battery 10 and a position that supports the vehicle battery 10. The first charging layer 142 has a charging connector for docking with the vehicle battery 10 placed in the first charging layer 142 to charge the vehicle battery 10. The charging connector can be a quick-connect connector as used in the prior art. In the example where the palletizer 150 picks up and places the vehicle battery 10 in the first charging layer 142 using a horizontal conveying method, the support structure in the first charging layer 142 is fixed. To realize the connection and disconnection of the charging connector and the vehicle battery 10, the charging connector is installed on the frame of the first battery rack 140 through a mechanism that can perform lifting motion.

[0069] Optionally, the charging connectors of the first battery rack 140 and the second battery rack 160 are each located at an end away from each other along the length direction D1 of the housing 111 to accommodate the operation of the palletizer 150 in loading and unloading batteries. This means that the orientation of the vehicle battery 10 located on the first charging layer 142 is opposite to the orientation of the vehicle battery 10 located on the second charging layer 161. For this purpose, the support platform 131 can also rotate about the rotation axis AX to a third angular position parallel to the length direction D1 of the housing 111. The angle by which the support platform 131 rotates about the rotation axis AX from the second angular position to the third angular position is approximately 180°. Thus, by using the battery swapping robot 130 to change the orientation of the vehicle battery 10, the palletizer 150 only needs to move the vehicle battery 10 in the height direction D3 and length direction D1 of the box 111 to ensure that the vehicle battery 10 correctly enters the first charging layer 142 and the second charging layer 161 without having to turn within the accommodating space 111f, thus adapting to the relatively short width of the box 111 (or accommodating space 111f).

[0070] Optionally, the number of cache layers 141 can be set to one, two, or other numbers. If the number of cache layers 141 is two or more, then each cache layer 141 is arranged along the height direction D3. Each cache layer 141 is used to house one vehicle battery 10.

[0071] Optionally, the number of first charging layers 142 can be two or other. Each first charging layer 142 is arranged along the height direction D3. Each first charging layer 142 is suitable for accommodating a vehicle battery 10.

[0072] In some embodiments, along the length direction D1 of the housing 111, the distance between the first battery rack 140 and the second battery rack 160 is greater than or equal to the length of the vehicle battery 10. This accommodates the space requirements of the palletizer 150 for transferring batteries along the height direction D3.

[0073] See also Figure 1 and Figure 2 In some embodiments, the charging / swapping station 100 further includes a fire extinguishing box 171 and a conveying assembly 172. The fire extinguishing box 171 is detachably connected to the outside of the housing 111. This facilitates the disassembly of the fire extinguishing box 171 during transportation, adapting to the need for reduced transportation costs in scenarios such as maritime transport. The fire extinguishing box 171 communicates with the receiving space 111f. The conveying assembly 172 is disposed within the receiving space 111f. The conveying assembly 172 is used to transfer vehicle batteries 10 in an abnormal state from the receiving space 111f to the fire extinguishing box 171. This allows for the transfer of abnormal vehicle batteries 10 to the fire extinguishing box 171 when some vehicle batteries 10 malfunction, isolating the abnormal vehicle batteries 10 from other vehicle batteries 10 within the receiving space 111f, thereby improving the electrical and fire safety performance of the charging / swapping station 100.

[0074] See Figure 1 Furthermore, the second battery rack 160 includes a housing layer 162 and a second charging layer 161. Along the height direction D3 of the housing 111, the housing layer 162 is located at the bottom of the second battery rack 160, and the conveying assembly 172 is disposed within the housing layer 162. Along the height direction D3 of the housing 111, the second charging layer 161 is located above the housing layer 162. The housing layer 162 can be understood as a gap at the bottom of the second battery rack 160. By providing the housing layer 162 at the bottom of the second battery rack 160 and accommodating the conveying assembly 172, the space utilization rate of the second battery rack 160 along the height direction D3 is improved. By providing the conveying assembly 172, the vehicle battery 10 can be transferred between the fire extinguisher box 171 and the second battery rack 160.

[0075] See Figure 1 and Figure 2In some embodiments, the charging and battery swapping station 100 also includes an electrical cabinet 181. The electrical cabinet 181 is disposed within the accommodating space 111f. The electrical cabinet 181 is located on the side of the second battery rack 160 away from the palletizer 150. By arranging the electrical cabinet 181 on the side of the second battery rack 160 away from the palletizer 150, the compactness of the structure within the accommodating space 111f along the length direction D1 is further improved, and the occupancy of the accommodating space 111f along the width direction D2 is reduced, thus adapting to the application requirements where the external dimensions of the container 111 are those of a standard shipping container. The electrical cabinet 181 can be understood as an integrated cabinet for housing one or more of circuit breakers, relays, terminal blocks, controllers, etc., and for connecting electrical cables.

[0076] In some embodiments, the charging / swapping station 100 further includes a charging device (not shown). The charging device is located outside the housing 111. The charging device is electrically connected to the battery rack to supply power to the battery rack. The charging device also includes a charging gun suitable for charging vehicles. This configuration satisfies both the power requirements of the internal electrical facilities of the charging / swapping station 100 and the direct charging needs of some new energy vehicles.

[0077] See Figure 1 In some embodiments, the charging and battery swapping station 100 further includes a lifting assembly 120. The lifting assembly 120 is disposed in the battery swapping channel 111e. The lifting assembly 120 is used to lift the vehicle so that the battery swapping robot 130 is positioned below the vehicle. Along the length direction D1 of the housing 111, the lifting assembly 120 includes two relatively independent lifting sections to adjust the vehicle's lifting position relatively independently. By providing the lifting assembly 120, application requirements where the battery swapping robot 130 cannot be fully lowered under the vehicle can be accommodated, preventing interference between the battery swapping robot 130 and the vehicle during its movement along the length direction D1 of the housing 111 to the battery swapping channel 111e.

[0078] See Figure 2 In some embodiments, the charging and battery swapping station 100 also includes a parking platform 113. The parking platform 113 is detachably connected to the end of the housing 111 along the width direction D2. This facilitates the disassembly of the parking platform 113 during transportation to meet transportation requirements such as maritime transport. The parking platform 113 corresponds to and protrudes from the housing 111 along the width direction D2 of the battery swapping channel 111e. The parking platform 113 is adapted for vehicles to enter, exit, and park in the battery swapping channel 111e along the width direction D2. The parking platform 113 can employ a parking platform from the prior art. For example, the parking platform 113 includes a vehicle-carrying section suitable for parking vehicles and a ramp section suitable for vehicles to move from the ground onto the vehicle-carrying section.

[0079] See Figure 1 and Figure 2Furthermore, the parking platform 113 may be equipped with a wheel positioning assembly 113a suitable for positioning the wheels 20 of the vehicle. The wheel positioning assembly 113a may employ a wheel positioning structure in the prior art.

[0080] See Figure 1 In some embodiments, to meet monitoring requirements, the charging and battery swapping station 100 also includes a camera 115 suitable for acquiring image information.
