[0040] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0041] The modular battery swap station according to the present invention is described below with reference to the accompanying drawings.

[0042] like Figures 1 to 5As shown, in an embodiment of the utility model, a modular battery swap station 100 includes a body module 1, a warehouse module 2, a conveying module and an external charging module 6. The body module 1 is provided with a battery swap channel 11, a battery room 12 and an equipment room 13 storing electronic control equipment in sequence along the length direction of the body module 1. The battery swap channel 11 and the battery room 12 are connected and used for vehicles to pass through, and the body module 1 is an integrally welded frame structure; the warehouse module 2 is arranged in the battery room 12, and the warehouse module 2 includes a transfer warehouse 21 and a charging warehouse 22 that are independent of each other. The transfer warehouse 21 is used to transfer the battery box 200, and the charging warehouse 22 is used to charge the battery box 200; the conveying module is installed on the top of the body module 1 and is electrically connected to the electronic control equipment. The conveying module is used to grab and transfer the battery box 200; the external charging module 6 is arranged outside the body module 1 and is used to supply power to the charging warehouse 22.

[0043] It can be understood that the modular battery swap station 100 in this embodiment is mainly used for battery swapping of commercial vehicles such as concrete mixing transport vehicles, port transport vehicles, and mining transport vehicles. A partition 18 is provided between the battery room 12 and the equipment room 13. The partition 18 isolates the battery room 12 and the equipment room 13 from each other, which can prevent the electric control equipment in the equipment room 13 from being affected by the equipment in the battery room 12. The electric control equipment in this embodiment can be an electric controller in the prior art. The top of the compartment module 1 is provided with an opening and an upper cover 17 covering the opening. After the conveying module is installed, the upper cover 17 is covered on the opening, which is convenient for the installation of the conveying module and can also protect the conveying module. In one embodiment, the external charging module 6 adopts a national standard charging pile. According to the different specifications of the battery box 200, a charging pile with a power of 120kW to 360kW can be configured. The charging system of the charging pile and the charging compartment 22 can be connected with a national standard charging gun. The charging pile can also be directly used as a charging facility to meet the different energy replenishment needs of the fleet.

[0044] like Figures 3 to 5 As shown, in one embodiment, the cross-section of the battery room 12 is rectangular, and four charging compartments 22 are arranged in a matrix to form a single-row serial layout. The transfer compartment 21 is located between two rows of charging compartments 22, and the transfer compartment 21 is arranged close to the equipment room 13. In this embodiment, a charging port is provided on the charging compartment 22, and the transfer compartment 21 is a support frame without a charging port. The transfer compartment 21 can be located between two charging compartments 22 along the left and right directions. Figure 3 The transfer warehouse 21 is arranged near the equipment room 13. The external charging module 6 can adopt the charging pile in the prior art. In other embodiments, the charging warehouse 22 can be arranged in a single row or in a ring.

[0045] The number of charging warehouses 22 in this embodiment is three or four, and the number of transfer warehouses 21 is one. The number of spare batteries is half of that of conventional battery swap stations, and the equipment cost and spare battery cost are reduced. The low investment makes the overall scale of the modular battery swap station 100 relatively small. The compartment module 1, the warehouse module 2, and the conveying module can all be prefabricated in the factory, and all debugging can be completed in the equipment factory. No large-scale construction is required on site. It is only necessary to level the ground and pre-bury the foundation in advance, and then simply set up and connect the power supply, which further reduces the on-site construction cost; and because the number of spare batteries is reduced, an external charging pile is used, and it has the ability to replace and charge batteries at the same time, and the demand for power expansion is reduced. It is easier to implement in areas with tight electricity demand, and has wide adaptability.

[0046] In addition, the battery swap service capacity of a modular battery swap station 100 can cover the needs of about 15 to 20 battery swap heavy trucks, which is suitable for most of the current commercial heavy truck fleets such as mines, ports, mixing stations, large-scale construction projects, and is flexible to deploy. When the demand expands, the single module can be added to double the service capacity, which is more suitable for the needs of various places to popularize electrification in batches; at the same time, external charging piles are directly used for in-station power replenishment, which can further reduce the investment for places where charging piles have been deployed. The length direction of the compartment in this embodiment is the front-to-back direction in the figure, and the width direction of the compartment is the left-to-right direction in the figure. The conveying module is located at the top of the battery swap channel 11, the battery room 12, and the equipment room 13. The cross-sections of the battery swap channel 11, the battery room 12, and the equipment room 13 are all rectangular.

[0047] The body module 1 in this embodiment is an integrally welded frame structure that can be prefabricated in the factory. When assembly is required, no large-scale construction is required on site. The body module 2 and the conveying module adopt a modular design. The body module 2 only includes a transfer warehouse 21 and a charging warehouse 22. They can be prefabricated in the factory and all debugging can be completed in the equipment factory. It is only necessary to level the ground and pre-embed the foundation in advance and then simply set up and connect the power supply, which further reduces the on-site construction cost. The conveying module is installed on the top of the body module 1, and the top-mounted battery replacement form can save space for the battery replacement channel 11, battery room 12 and equipment room 13 located at the bottom, and an external charging module 6 is used. It has the ability to replace and charge batteries at the same time, and the demand for power expansion is reduced. It is easier to implement in areas with tight electricity demand and has a wide adaptability. The compartment module 1 in this embodiment adopts a prefabricated structure similar to the battery swap station body of a modular integrated station. Each module can be produced and assembled in a prefabricated equipment manner. The integrated design can reduce a large amount of on-site construction, and combined with the flexible combination of the built-in charging compartment 22 and the external charging module 6, the built-in charging module is eliminated, which can facilitate the assembly of the modular battery swap station 100, realize the miniaturization of the modular battery swap station 100, and improve the assembly convenience and efficiency of the modular battery swap station 100.

[0048] In addition, the body module 1, the warehouse module 2, and the conveying module are manufactured, assembled, and debugged in the factory. After completion, they are directly transported to the site of use by a semi-trailer. After being quickly connected and fixed using general lifting equipment, they can be put into use after being connected to the main power supply cable. They can be put into use within 2 to 4 hours at the fastest, reducing the time for on-site installation and adjustment. The modular battery swap station 100 in this embodiment can quickly expand capacity by connecting multiple modules in series and parallel when capacity expansion is required.

[0049] like Figure 1 and Figure 2 As shown, the conveying module includes a main frame mechanism 3, an inner frame mechanism 4 and a lifting mechanism 5.

Figures 1 to 3 As shown, the length direction of the compartment is the front-to-back direction in the figure, the width direction of the compartment is the left-to-right direction in the figure, and the hoisting mechanism 5 can lift the battery box 200 in the up-down direction. The conveying module in this embodiment adopts a structural form in which the main frame mechanism 3 nests the inner frame mechanism 4 and the hoisting mechanism 5, which can improve the structural compactness of the conveying module and reduce the occupied area of ​​the conveying module. The main frame mechanism 3 can drive the battery box 200 to move in the front-to-back direction, the inner frame mechanism 4 can drive the battery box 200 to move in the left-to-right direction, and the hoisting mechanism 5 can grab and lift the battery box 200, so as to realize the conveying of the battery box 200 in three-dimensional directions.

[0050] In one embodiment, the main frame mechanism 3 includes a main frame 31 with rollers 32 and a first driving member for driving the rollers 32. The top of the body module 1 is provided with a wheel rail 16 that is in rolling contact with the rollers 32, and the inner frame mechanism 4 is installed on the main frame 31. The first driving member in this embodiment can be a driving motor. The wheel rail 16 in this embodiment is arranged on the top of the body module 1 along the front-to-back direction. The track layout can improve the structural compactness of the conveying module. The wheel rail 16 can be a steel rail extending along the front-to-back direction. The body module 1 is provided with wheel rails 16 on both the left and right sides. The rollers 32 can be friction wheels. Four rollers 32 can be arranged on the main frame 31, one of which is a driving wheel and the other three are driven wheels. The main frame 31 is driven to move along the extension direction of the wheel rail 16 by the first driving member at the wheel end of the driving wheel. The structure is simple and the movement stability of the conveying module can be ensured.

[0051] Specifically, the inner frame mechanism 4 includes a sub-frame 41 with a gear and a second driving member for driving the gear, and the inner wall of the hollow cavity is provided with a rack 33 meshing with the gear. The sub-frame 41 in this embodiment can be connected to the main frame 31 by meshing with the gear rack 33, the rack 33 extends in the left and right direction, two racks 33 can be provided on the main frame 31, and the two racks 33 are arranged at intervals in the front and back direction. Two gears are provided on the sub-frame 41, one is a driving gear connected to the second driving member, and the other is a driven gear. The gear is driven by the second driving member to drive the sub-frame 41 to achieve horizontal lateral displacement. In this embodiment, the inner frame mechanism 4 and the main frame mechanism 3 are connected by meshing with the gear rack 33, and the driving movement of the sub-frame 41 is also facilitated, and the structure is simple and easy to assemble.

[0052] It can be understood that the hoisting mechanism 5 includes a clamp 51 and a lifting winch 52 installed on the sub-frame 41, the clamp 51 is used to grab or release the battery box 200, and the lifting winch 52 is used to lift the clamp 51. The clamp 51 in this embodiment can adopt a gripper in the prior art, which can grab or release the battery box 200 under the drive of the motor, and the steel wire inside the lifting winch 52 can lift the clamp 51. The lifting winch 52 in this embodiment can be embedded in the middle cavity of the sub-frame 41, and further improve the structural compactness of the conveying module.

[0053] It should be noted that the modular battery swap station 100 also includes a support module 7 that securely connects the body module 1 to the ground. The support module 7 and the body module 1 form an overhead layer 8, and the external charging module 6 is accommodated in the overhead layer 8. The number of charging compartments 22 in this embodiment can be adjusted according to actual conditions. Considering the economy, charging speed and battery swapping time, the number of charging compartments 22 is generally 3 to 4. The overhead layer 8 is located at the lower end of the body module 1. Accommodating the external charging module 6 in the overhead layer 8 can protect the external charging module 6 while improving the space utilization of the modular battery swap station 100. In other embodiments, the modular battery swap station 100 is located outside the overhead layer 8.

[0054] In one embodiment, the support module 7 includes a plurality of support legs 71, one end of the support leg 71 is used to be fixedly connected to the embedded parts on the ground, and the other end is used to be connected to the body module 1. The support legs 71 in this embodiment may be made of welded steel structures. When assembling the modular battery swap station 100, since the body module 1, the warehouse module 2 and the conveying module can be pre-installed and debugged in the equipment factory, it is only necessary to fix one end of the support leg 71 to the embedded parts on the ground at the assembly site. The embedded parts may be embedded bolts, and then the top of the support leg 71 is connected to the body module 1 to complete the assembly of the modular battery swap station 100. The support legs 71 and the body module 1 may be connected and fixed by bolts or mortise and tenon structures. The height of the structural parts between the support legs 71 and the body module 1 may also be adjusted to ensure that the height of the battery swap channel 11 matches the height of the chassis of different vehicles.
