Description

Technical Field

[0001] This application relates to the field of battery swapping equipment technology, specifically to a battery swapping device, a mobile battery swapping device, and a battery swapping station. Background Technology

[0002] For construction machinery with limited mobility, such as excavators and loaders, existing technologies typically employ mobile battery swapping equipment to provide battery replacement services for rapid power replenishment. After the mobile battery swapping equipment has replaced the battery for the construction machinery, it needs to return to the battery swapping station to replenish power by directly replacing the battery pack.

[0003] However, during the process of removing or installing the battery pack from the mobile battery swapping equipment, the lifting devices and other structures of the mobile battery swapping equipment interfere with the movement of the battery pack, resulting in low battery pack replacement efficiency. Utility Model Content

[0004] In view of this, this application provides a battery swapping device, a mobile battery swapping equipment, and a battery swapping station to solve or improve the problem of low battery pack replacement efficiency during the process of removing or installing battery packs from or into the mobile battery swapping equipment.

[0005] In a first aspect, this application provides a battery swapping device, including a base, an energy storage compartment, at least one replenishment compartment, a drive mechanism, and a hoisting device. The energy storage compartment is disposed on the base and is used to hold a battery pack; at least one replenishment compartment is used to hold the battery pack, the replenishment compartment being movably disposed on the base, and at least a portion of the replenishment compartment extending out of the base; the drive mechanism is disposed on the base and is throttle-connected to the replenishment compartment; the hoisting device is used to hoist the battery pack from the energy storage compartment to an external electrical device, and to move the battery pack between the energy storage compartment and the replenishment compartment.

[0006] Beneficial effects: By setting a drive mechanism on the base, the drive mechanism can drive the recharge compartment to move relative to the base, so that at least part of the recharge compartment can extend or retract from the base. In this way, the recharge compartment drives the battery pack to extend or retract from the base. During the process of the battery pack being taken out or installed from the battery swapping device, the recharge compartment extends at least part of the battery pack from the base, effectively avoiding interference caused by the hoisting device to the movement of the battery pack, thereby improving the battery pack replacement efficiency.

[0007] In one alternative embodiment, the recharge compartment is rotatably mounted on the base, and the drive mechanism includes a rotary drive device for driving the recharge compartment to rotate.

[0008] Beneficial effects: Driven by the rotary drive device, the charging compartment rotates relative to the base, causing part of the charging compartment to extend out of the base while the remaining part remains on the base. This allows the battery pack portion of the charging compartment to extend out of the base, facilitating battery pack removal or installation. Simultaneously, the base provides partial support to the charging compartment, preventing it from being completely suspended relative to the base and bringing the battery pack's center of gravity closer to the base, thereby improving the overall stability of the mobile battery swapping equipment during charging operations.

[0009] In one alternative embodiment, the recharge compartment has a first end and a second end opposite to each other, the first end of the recharge compartment is rotatably connected to the base, and the second end of the recharge compartment can enter and exit the base along the rotation direction of the recharge compartment.

[0010] Beneficial effects: The charging compartment can rotate relative to the base around its first end axis, and by driving the charging compartment to rotate, its second end can enter and exit the base. In this way, a large part of the charging compartment can enter and exit the base with a small angle of rotation, which facilitates the rotation drive device to move the charging compartment, and can keep the remaining part of the charging compartment on the base, thus improving the overall stability of the mobile battery swapping equipment during charging operations.

[0011] In one optional embodiment, the recharge compartment is retractably mounted on the base along a first direction, and the driving mechanism includes a telescopic driving device for driving the recharge compartment to extend or retract.

[0012] Beneficial effects: The recharge compartment can be retracted along the first direction by the telescopic drive device. During the recharge operation, the recharge compartment is suitable to extend fully out of the base, which further increases the distance between the recharge compartment extending out of the base and the lifting device. This further avoids interference caused by the lifting device to the movement of the battery pack during the process of taking the battery pack out or putting it into the mobile battery swapping equipment, thereby further improving the battery pack replacement efficiency.

[0013] In one optional embodiment, the drive mechanism includes a rotary drive device, which includes a drive motor. The output shaft of the drive motor is connected to the refueling compartment via a direct drive, a gear transmission mechanism, or a chain transmission mechanism. And / or, the drive mechanism includes a telescopic drive device, which is configured as a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod.

[0014] Beneficial effects: The rotary drive device uses a drive motor as a power source, transmitting the driving force of the motor's output shaft to the energy replenishment compartment through direct or indirect transmission, enabling the energy replenishment compartment to rotate relative to the base. Furthermore, the rotary drive device has a simple structure and is easy to use. The telescopic drive device uses a telescopic rod as a power source, transmitting the driving force of the telescopic rod to the energy replenishment compartment through direct transmission, enabling the energy replenishment compartment to move relative to the base in a first direction. The telescopic drive device also has a simple structure and is easy to use.

[0015] In one alternative embodiment, the lifting device includes a frame and a first lifting assembly. The frame is disposed on the base; the first lifting assembly is disposed on the frame and is used to drive the battery pack to move on the base.

[0016] Beneficial effects: The frame supports the first lifting device assembly, allowing it to move along the frame. The first lifting device suspends the battery pack, enabling it to move between the energy replenishment compartment and the energy storage compartment, facilitating subsequent energy replenishment operations. Furthermore, the lifting device also allows the battery pack to move between the energy storage compartment and external electrical equipment, facilitating battery swapping operations on external devices.

[0017] Secondly, this application provides a mobile battery swapping device, including a carrier on which the battery swapping device described in any of the above claims is disposed.

[0018] Beneficial effects: The aforementioned battery swapping device is mounted on a carrier, which serves as a mobile platform, providing installation space and transportation capabilities for the device, thus enhancing its overall mobility. The battery swapping device comprises a base, an energy storage compartment, at least one recharge compartment, a drive mechanism, and a hoisting device. When recharging the device, the carrier transports it to a predetermined location, the hoisting device places the battery pack to be replaced into the recharge compartment, and then the drive mechanism at least partially pushes the recharge compartment out of the base. This effectively avoids interference from the hoisting device on the battery pack's movement during subsequent removal and replacement of the battery pack, thereby improving battery pack replacement efficiency.

[0019] In one alternative embodiment, the first direction of the base is parallel to the width direction of the vehicle.

[0020] Beneficial effects: During the process of extending the refueling compartment from the base by rotation or by horizontal extension, the refueling compartment extends from the base along the first direction. Since the first direction of the base is parallel to the width direction of the vehicle, the refueling compartment can extend from the side of the vehicle. The side area of ​​the vehicle is relatively larger than the tail area, which facilitates the refueling operation.

[0021] Thirdly, this application provides a battery swapping station, including a power replenishment device, which is used to replenish and swap the power of the mobile battery swapping equipment described in any of the above claims.

[0022] Beneficial effects: The energy replenishment device is located on the side of the vehicle. After the energy replenishment compartment extends from the side of the vehicle, the energy replenishment device can be used to quickly replace the battery pack in the energy replenishment compartment, thereby further improving the energy replenishment efficiency of the battery swapping device.

[0023] In one alternative embodiment, the power replenishment device includes a rotary platform, a support arm, and a second lifting assembly. The support arm is rotatably mounted on the rotary platform; the second lifting assembly is mounted on the support arm and is adapted to drive the battery pack between the power replenishment compartment and a replacement compartment outside the vehicle.

[0024] Beneficial effects: The slewing platform supports the support arm and drives it to rotate. The second lifting device on the support arm is used to lift the battery pack, which facilitates the replacement of the battery pack in the recharge compartment. Attached Figure Description

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Please refer to Figures 1-5 In a first aspect, this application provides a battery swapping device, including a base 1, an energy storage compartment 2, at least one replenishment compartment 3, a drive mechanism, and a hoisting device 4. The energy storage compartment 2 is disposed on the base 1 and is used to place a battery pack 100; at least one replenishment compartment 3 is used to place the battery pack 100, the replenishment compartment 3 is movably disposed on the base 1, and at least a portion of the replenishment compartment 3 can extend out of the base 1; the drive mechanism is disposed on the base 1 and is drively connected to the replenishment compartment 3; the hoisting device 4 is used to hoist the battery pack 100 on the energy storage compartment 2 to an external electrical device, and to hoist the battery pack 100 to move between the energy storage compartment 2 and the replenishment compartment 3.

[0040] First, it should be noted that, as Figure 3 As shown, in this embodiment, the first direction X is the width direction of the vehicle 7. Of course, those skilled in the art can adjust the specific direction referred to by the first direction X according to actual needs.

[0041] In this embodiment, the battery swapping device described above can be used as a fixed battery swapping station or mounted on the vehicle 7 to function as a mobile battery swapping device. The vehicle 7 can be a gasoline vehicle, a new energy vehicle, or other ground-based mobile equipment.

[0042] In this embodiment, the external electrical equipment can be construction machinery with relatively limited mobility, such as excavators and loaders.

[0043] In this embodiment, refer to Figure 1 The base 1 serves as the basic platform for supporting the battery pack 100, and it is equipped with multiple compartments, including multiple energy storage compartments 2 and at least one energy replenishment compartment 3. Each energy storage compartment 2 and each energy replenishment compartment 3 is preferably capable of holding one battery pack 100, thereby separating the battery packs 100 using the energy storage compartments 2 and the energy replenishment compartments 3, which facilitates the storage, hoisting, and movement of each battery pack 100. The multiple energy storage compartments 2 enable the batch storage of the battery packs 100, and the energy replenishment compartment 3 serves as a node for temporary storage of the battery packs 100. During the energy replenishment operation of the battery swapping device, the battery packs 100 are hoisted by the hoisting device 4 set on the base 1, allowing the battery packs 100 to move between the energy storage compartments 2 and the energy replenishment compartment 3.

[0044] Since the battery swapping device is usually equipped with a hoisting device 4 for hoisting the battery pack 100, when the battery pack 100 is located in the energy replenishment compartment 3 and is in a state of waiting to be replaced, the external energy replenishment device 8 usually needs to be moved above the base 1 and aligned with the battery pack 100 on the energy replenishment compartment 3. This causes the hoisting device 4 to easily interfere with the energy replenishment device 8, affecting the energy replenishment device 8 in lifting the battery pack 100 off the energy replenishment compartment 3.

[0045] Therefore, the charging compartment 3 is movably mounted on the base 1, and a drive mechanism is provided on the base 1. The drive mechanism can drive the charging compartment 3 to move relative to the base 1, so that at least part of the charging compartment 3 can extend or retract from the base 1. Thus, the charging compartment 3 drives the battery pack 100 to extend or retract from the base 1. During the process of the battery pack 100 being taken out or put into the battery swapping device, the charging compartment 3 extends at least part of the battery pack 100 out of the base 1, effectively avoiding interference caused by the lifting device 4 to the movement of the battery pack 100, thereby improving the battery pack 100 replacement efficiency.

[0046] In this embodiment, a recharge compartment 3 is provided on the base 1. Besides facilitating recharge operations for the battery swapping device, the recharge compartment 3 can also serve as a temporary storage point for the battery pack 100 during the battery swapping operation of external electrical equipment. Specifically, when the battery swapping device performs a battery swapping operation, the battery pack 100 is hoisted by the hoisting device 4, allowing it to move between the energy storage compartment 2, the recharge compartment 3, and the external electrical equipment. The battery pack 100 replaced by the external electrical equipment is temporarily stored in the recharge compartment 3, facilitating battery pack replacement by the external electrical equipment and thus improving the battery swapping efficiency of the device.

[0047] Furthermore, the presence of a recharge compartment 3 on the base 1 allows for the transfer of battery packs 100 from multiple energy storage compartments 2. Normally, the recharge compartment 3 is empty; during the transfer operation, a battery pack 100 from one energy storage compartment 2 is temporarily stored in the recharge compartment 3, allowing battery packs 100 from other energy storage compartments 2 to move between them. This change in the position of the battery packs 100 on the base 1 facilitates subsequent recharge and battery swapping operations.

[0048] Optionally, refer to Figure 4 Positioning guide grooves are provided on both the energy storage compartment 2 and the energy replenishment compartment 3. The positioning guide grooves are used to limit and constrain the battery pack 100 to prevent the battery pack 100 placed on it from moving or becoming misaligned when the battery swapping device is moved.

[0049] Optionally, the number and relative arrangement of energy storage compartments 2 and energy replenishment compartments 3 can be adjusted according to actual conditions. Preferably, the energy replenishment compartment 3 is located at the outer edge of the battery swapping device to facilitate its extension from the base 1 for energy replenishment operations.

[0050] In one embodiment, refer to Figure 1 , Figure 2 The recharge compartment 3 is rotatably mounted on the base 1, and the driving mechanism includes a rotary drive device 5 for driving the recharge compartment 3 to rotate.

[0051] In this embodiment, the fixed end of the rotary drive device 5 is mounted on the base 1, and the output end of the rotary drive device 5 is connected to the energy replenishment compartment 3 directly or indirectly. Under the driving action of the rotary drive device 5, the energy replenishment compartment 3 can rotate relative to the base 1. When the battery swapping device itself is recharged, the battery pack 100 that has been depleted on the energy storage compartment 2 is first moved to the energy replenishment compartment 3 using the hoisting device 4. Then, the rotary drive device 5 is started, and the energy replenishment compartment 3 is driven to rotate. The energy replenishment compartment 3 causes the battery pack 100 to extend at least partially out of the base 1. After the battery pack 100 is removed from the energy replenishment compartment 3 using the energy replenishment device 8, the fully charged battery pack 100 is placed on the energy replenishment compartment 3. Then, the rotary drive device 5 is started again, and the energy replenishment compartment 3 is reset. Finally, the battery pack 100 on the energy replenishment compartment 3 is moved to the energy storage compartment 2 using the hoisting device 4, completing the energy replenishment operation of the battery swapping device.

[0052] With this configuration, the charging compartment 3 rotates relative to the base 1 under the drive of the rotary drive device 5, causing part of the charging compartment 3 to extend out of the base 1 while the remaining part remains on the base 1. This allows part of the battery pack 100 on the charging compartment 3 to extend out of the base 1, facilitating the removal or installation of the battery pack 100. Simultaneously, the base 1 provides partial support for the charging compartment 3, preventing it from being completely suspended relative to the base 1. Especially when the battery swapping device is mounted on the carrier 7, this partially suspended configuration brings the center of gravity of the battery pack 100 closer to the base 1, thereby improving the overall stability of the mobile battery swapping equipment during charging operations.

[0053] In one embodiment, refer to Figure 2 The energy replenishment compartment 3 has a first end 31 and a second end 32. The first end 31 of the energy replenishment compartment 3 is rotatably connected to the base 1, and the second end 32 of the energy replenishment compartment 3 can enter and exit the base 1 along the rotation direction of the energy replenishment compartment 3.

[0054] In this embodiment, the structural dimensions of the charging compartment 3 are adapted to the battery pack 100. The first end 31 of the charging compartment 3 or the area near the first end 31 is rotatably connected to the base 1 through the rotating shaft 10, so that the charging compartment 3 can rotate around the rotating shaft 10, thereby extending the second end 32 of the charging compartment 3 out of the base 1.

[0055] Driven by the rotary drive device 5, the charging compartment 3 can rotate at a small angle, allowing most of its area to move out of or into the base 1, thus shortening the time required for the charging compartment 3 to move to the preset position and improving moving efficiency. Furthermore, even after most of the charging compartment 3 has moved out of the base 1, the remaining area of ​​the charging compartment 3 can still remain on the base 1, improving the overall stability of the mobile battery swapping equipment during charging operations.

[0056] In another embodiment, in addition to using the aforementioned rotation method to enter and exit the base 1, the recharge compartment 3 also refers to... Figure 3 The recharge compartment 3 can also be retractably mounted on the base 1 along the first direction X. The drive mechanism includes a telescopic drive device 6, which is used to drive the recharge compartment 3 to extend and retract.

[0057] In this embodiment, when the base 1 is installed on the carrier 7, the first direction X is preferably parallel to the width direction of the carrier 7. The fixed end of the telescopic drive device 6 is fixed to the base 1, and the movable end of the telescopic drive device 6 can telescopically move along the first direction X, thereby driving the energy replenishment compartment 3 to extend or retract into the base 1 along the first direction X. When the battery swapping device itself is recharged, the battery pack 100 that has been depleted on the energy storage compartment 2 is first moved to the energy replenishment compartment 3 using the hoisting device 4. Then, the telescopic drive device 6 is activated to push the energy replenishment compartment 3 out of the base 1. After the battery pack 100 is removed from the energy replenishment compartment 3 using the energy replenishment device 8, the fully charged battery pack 100 is placed on the energy replenishment compartment 3. Then, the telescopic drive device 6 is activated again to reset the energy replenishment compartment 3. Finally, the battery pack 100 on the energy replenishment compartment 3 is moved to the energy storage compartment 2 using the hoisting device 4, completing the energy replenishment operation of the battery swapping device.

[0058] With this configuration, the recharge compartment 3 can be retracted along the first direction X by the telescopic drive device 6. During the recharge operation, the recharge compartment 3 is suitable to extend fully out of the base 1, which further increases the distance between the recharge compartment 3 extending out of the base 1 and the lifting device. This further avoids interference caused by the lifting device 4 to the movement of the battery pack 100 during the process of taking the battery pack 100 out of or into the mobile battery swapping equipment, thereby further improving the replacement efficiency of the battery pack 100.

[0059] Optionally, a slide rail (not shown in the figure) is fixed on the base 1, and the slide rail and the energy replenishment compartment 3 are in sliding engagement. When the energy replenishment compartment 3 is driven by the rotary drive device 5 or the telescopic drive device 6, the specific structure of the slide rail is adaptively adjusted according to the movement trajectory of the energy replenishment compartment 3.

[0060] In one specific embodiment, the different ways in which the recharge compartment 3 extends from the base 1 determine the different structures of the rotary drive device 5 and the telescopic drive device 6. The rotary drive device 5 and the telescopic drive device 6 adopt existing drive devices that can realize the rotary extension or linear extension of the recharge compartment 3. The specific structures of the rotary drive device 5 and the telescopic drive device 6 are described exemplarily below. The drive mechanism includes the rotary drive device 5, which includes a drive motor. The output shaft of the drive motor is connected to the recharge compartment 3 through one of the following: direct drive, gear transmission mechanism, or chain transmission mechanism; and / or, the drive mechanism includes the telescopic drive device 6, which is configured as one of the following: hydraulic telescopic rod, pneumatic telescopic rod, or electric telescopic rod.

[0061] Specifically, refer to Figure 2 When the drive mechanism adopts a rotary drive device 5, the rotary drive device 5 includes a drive motor, which can be fixed on the base 1. The output shaft of the drive motor is connected to the energy replenishment compartment 3 through one of a direct drive, a gear transmission mechanism, or a chain transmission mechanism. The energy replenishment compartment 3 is rotatably connected to the base 1 through a rotating shaft 10.

[0062] If a direct drive method is used, the rotary drive motor can be directly connected to the rotating shaft 10 via a coupling. In this case, the rotary drive motor is preferably a geared motor, achieving direct connection with the energy replenishment compartment 3. Alternatively, the rotary drive motor can be connected to the rotating shaft 10 via a gear transmission mechanism or a chain transmission mechanism. That is, a gear is fixedly fitted onto the outside of the rotating shaft 10, and power is indirectly transmitted through gear meshing with the gear transmission mechanism or gear-chain meshing with the chain transmission mechanism. Of course, a telescopic swing arm can also be arranged on the base 1, with both ends of the swing arm hinged to the side walls of the base 1 and the energy replenishment compartment 3, respectively. By adjusting the position of the swing arm and the connection structure, the energy replenishment compartment 3 can also be rotated relative to the base 1.

[0063] Specifically, refer to Figure 3 When the drive mechanism uses a telescopic drive device 6, the telescopic drive device 6 is configured as one of a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod. The fixed end of the telescopic rod is fixed to the base 1, and the telescopic end of the telescopic rod is connected to the charging compartment 3. By moving the telescopic rod, the charging compartment 3 can be driven to move horizontally along the first direction X. Furthermore, when the drive mechanism uses a telescopic drive device 6, a support frame that can extend along the first direction X can be provided on the side of the base 1. The support frame is located below the charging compartment 3. When the charging compartment 3 extends out of the base 1, the support frame extends synchronously and supports the charging compartment 3, thereby further improving the support strength of the charging compartment 3 for the battery pack 100.

[0064] Of course, in addition to the separate use of the rotary drive device 5 and the telescopic drive device 6, the above-mentioned drive mechanisms can also be used together. That is, the battery swapping device is provided with two or more energy replenishment compartments 3, so that the rotary drive device 5 and the telescopic drive device 6 can be applied to different energy replenishment compartments 3. Thus, when dealing with different working conditions, different energy replenishment compartments 3 can be selected for energy replenishment operations.

[0065] In one embodiment, refer to Figure 4 The hoisting device 4 includes a frame 41 and a first lifting assembly 42. The frame 41 is disposed on the base 1; the first lifting assembly 42 is disposed on the frame 41 and is used to drive the battery pack 100 to move on the base 1.

[0066] In this embodiment, the first lifting assembly 42 is supported by the frame 41, allowing the first lifting assembly 42 to move along the frame 41. The first lifting assembly 42 is used to lift the battery pack 100, enabling the battery pack 100 on the base 1 to move between the energy replenishment compartment 3 and the energy storage compartment 2. This allows the battery pack 100 on the energy storage compartment 2 to be moved to the energy replenishment compartment 3, or vice versa, facilitating subsequent energy replenishment operations. Lifting the battery pack 100 using the first lifting assembly 42 also allows the battery pack 100 on the base 1 to move between the energy storage compartment 2 and external electrical equipment, facilitating battery swapping operations for external electrical equipment.

[0067] Understandably, the frame 41 is typically supported on the base 1 by a telescopic arm 43, allowing the frame 41 to extend or retract under the drive of the telescopic arm 43. Therefore, in this embodiment, the extension position of the recharge compartment 3 needs to be offset from the position of the telescopic arm 43 to avoid interference from the telescopic arm 43 on the movement of the recharge compartment 3.

[0068] Understandably, the aforementioned first lifting device assembly 42 is a conventional lifting device structure. For example, the first lifting device assembly 42 includes a longitudinal moving mechanism, a lateral moving mechanism, a lifting mechanism, a rotating mechanism, and a gripper. The longitudinal and lateral moving mechanisms are conventional XY-direction slide rail moving structures. The lifting mechanism includes a liftable rope and a support platform mounted on the rope. One end of the rope is mounted on the lateral moving mechanism, and the support platform moves vertically by extending and retracting the rope. The rotating mechanism is mounted on the support platform, and a gripper is mounted on the rotating end of the rotating mechanism, thereby enabling the first lifting device assembly 42 to move the battery pack 100. Since the first lifting device assembly 42 can use a conventional lifting device structure, no further limitations are imposed on the first lifting device assembly 42 here.

[0069] Secondly, this application provides a mobile battery swapping device, including a carrier 7, on which the battery swapping device described above is installed.

[0070] In this embodiment, the aforementioned battery swapping device is arranged on a carrier 7. The carrier 7 serves as a mobile platform, providing installation space and transportation functions for the battery swapping device, thus enabling the overall battery swapping device to be mobile. The battery swapping device has a base 1, an energy storage compartment 2, at least one energy replenishment compartment 3, a drive mechanism, and a hoisting device 4. When replenishing the battery swapping device, the carrier 7 is used to transport the battery swapping device to a preset position. The hoisting device 4 is used to place the battery pack 100 to be replaced into the energy replenishment compartment 3. Subsequently, the drive mechanism is used to push at least part of the energy replenishment compartment 3 out of the base 1. During the subsequent removal and replacement of the battery pack 100 on the energy replenishment compartment 3, interference caused by the hoisting device 4 to the movement of the battery pack 100 is effectively avoided, thereby improving the battery pack 100 replacement efficiency.

[0071] In one embodiment, refer to Figure 3 , Figure 4 The first direction X of the base 1 is parallel to the width direction of the vehicle 7.

[0072] In this embodiment, during the process of extending the recharge compartment 3 from the base 1 by rotation or by horizontal extension of the base 1, the recharge compartment 3 extends from the base 1 along the first direction X. Since the first direction X of the base 1 is parallel to the width direction of the carrier 7, the recharge compartment 3 can extend from the side of the carrier 7. The side area of ​​the carrier 7 is larger than the tail area, which facilitates the recharge operation.

[0073] Thirdly, referring to Figure 1 , Figure 5 This application provides a battery swapping station, including a power replenishment device 8, which is used to replenish the power of any of the mobile battery swapping devices described above.

[0074] In this embodiment, the battery swapping station can be configured as a mobile battery swapping station or a fixed battery swapping station. During the replenishment operation, the replenishment device 8 is located in the side area of ​​the carrier 7. After the replenishment compartment 3 extends from the side of the carrier 7, the replenishment device 8 grabs the battery pack 100 on the replenishment compartment 3 and places the battery pack 100 in the replacement compartment 9 outside the mobile battery swapping device. Then, the replenishment device 8 grabs a new battery pack 100 and places the battery pack 100 in the replenishment compartment 3. By using the cooperation of the replenishment device 8 and the replenishment compartment 3, the battery pack 100 on the replenishment compartment 3 can be quickly replaced, thereby further improving the replenishment efficiency of the battery swapping device.

[0075] In one embodiment, refer to Figure 5The energy replenishment device 8 includes a rotary platform 81, a support arm 82, and a second lifting device assembly 83. The support arm 82 is rotatably mounted on the rotary platform 81; the second lifting device assembly 83 is mounted on the support arm 82 and is adapted to drive the battery pack 100 to move between the energy replenishment compartment 3 and the replacement compartment 9 outside the carrier 7.

[0076] In this embodiment, the rotary platform 81 can be installed on a fixed base, making the battery swapping station a fixed station. Alternatively, the rotary platform 81 can be installed on another vehicle, making the battery swapping station a mobile station. The rotary platform 81 supports the support arm 82 and drives the support arm 82 to rotate. The second lifting assembly 83 on the support arm 82 is used to lift the battery pack 100, facilitating the replacement of the battery pack 100 on the energy replenishment compartment 3.

[0077] Understandably, the aforementioned second lifting device assembly 83 is also a conventional lifting device structure, and its specific structure can be similar to that of the first lifting device assembly 42. Since the gripper on the second lifting device assembly 83 also has a rotation function, when the recharge compartment 3 extends out of the base 1 in a rotating manner, the second lifting device assembly 83 can adjust the angle of its gripper to match the tilt angle of the battery pack 100 on the recharge compartment 3, thereby facilitating the second lifting device assembly 83 to grip the battery pack 100 and improving the battery pack 100 replacement efficiency.

[0078] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
