Description

[0001] This application claims the priority of Chinese Patent Application No. 202410380046.4 with a filing date of March 29, 2024. This application incorporates the entire text of the above-mentioned patent application by reference. Technical Field

[0002] This application relates to the technical field of electric vehicle battery swapping, and particularly to a battery swapping station. Background Art

[0003] With the development and popularization of new energy vehicles, the battery pack quick swapping technology has also developed rapidly. For large vehicles, such as heavy trucks or light trucks, the vehicle body and the load are very heavy, resulting in a relatively high demand for the battery pack capacity of large vehicles. Only a sufficiently large-capacity electric energy can support the use of large vehicles.

[0004] In the traditional battery swapping mode, large vehicles in the new energy series fix a relatively large battery container on the vehicle's beam through a top lifting method. The battery container is arranged adjacent to the driver's cab, which brings great safety hazards to the driver and the vehicle itself during driving and top lifting battery swapping; moreover, if the battery fails, etc., it will directly cause personal injury to the driver. In addition, the top lifting method has high requirements for the site of the battery swapping station, and the battery swapping station needs to have a sufficiently large area to execute the transfer of the lifting equipment for the battery and the storage of the battery, etc., resulting in a high construction cost.

[0005] Therefore, for large vehicles, there is an urgent need for a safer, more reliable and easier-to-popularize battery swapping mode. For example, the chassis-type battery swapping mode of passenger cars is adopted. In the chassis-type battery swapping mode, it is necessary to control the overall movement of the battery swapping equipment to the battery swapping position below the battery swapping vehicle, and then perform the lifting operation and the operation of disassembling or installing the battery pack to complete the entire battery swapping process. During this battery swapping process, due to the limited space below the body of the battery swapping vehicle, especially for heavy truck battery swapping vehicles, etc., it is difficult to drive and park on a platform higher than the ground, making the space below the body of the battery swapping vehicle more restricted. If the battery swapping equipment is used for battery swapping, during the battery swapping process, the battery swapping equipment needs to carry the depleted battery or the fully charged battery back and forth to move in and out of the bottom of the battery swapping vehicle. To meet the power demand of heavy truck battery swapping vehicles, the battery packs are very large, which greatly limits the available space of the battery swapping equipment. At this time, if the available space of the battery swapping equipment is to be increased, the battery swapping equipment can only move in the space sunken from the ground. Due to the multiple drives of the heavy truck battery swapping vehicle before and after battery swapping, this will inevitably lead to the unreliability of the ground structure in this way, making it difficult to bear the multiple loads of the battery swapping vehicle, reducing the service life of the equipment structure, and there are also safety hazards for the battery swapping vehicle.

[0006] In addition, a battery swapping station usually has a battery rack capable of carrying multiple battery packs. There are many battery compartments on the battery rack that can temporarily store battery packs. The depleted batteries removed from the battery swapping vehicle need to be sent into the battery compartments for storage and charging. At the same time, the fully charged batteries to be installed on the battery swapping vehicle need to be obtained from the battery rack. Therefore, the battery transfer device needs to unlock the depleted batteries on the battery swapping vehicle through a battery tray and a unlocking pin, transfer them into the battery compartments for charging, and take out the fully charged batteries in the battery compartments, install and lock them onto the battery swapping vehicle. For the chassis-type battery swapping mode, a relatively popular method in the prior art is to suspend the battery pack on the chassis of the battery swapping vehicle through a battery locking mechanism. This method is friendly to the battery tray, and the battery locking mechanism on the chassis will not interfere with the battery tray under the battery pack. However, the depleted batteries sent into the battery compartments are usually borne by the supporting structure at the bottom of the battery compartment. Therefore, a space for avoiding the battery tray needs to be set on the supporting structure, which brings difficulties to the design of the supporting structure. Therefore, most battery racks carry battery packs through two longitudinal beams, and the battery tray enters the battery compartment between the two longitudinal beams. However, the load-bearing stability of the two longitudinal beams is poor and the safety risk is high. Moreover, since the installation method of the battery pack on the battery swapping vehicle is different from its storage method in the battery compartment, it increases the burden of the battery transfer device to interact with the battery packs between the battery compartment and the battery swapping vehicle, and the battery swapping efficiency is low.

[0007] Thus, there are many drawbacks in the prior art that need to be further improved and enhanced. Summary of the Utility Model

[0008] This application provides a battery swapping station, which realizes the battery disassembly and assembly operation for the battery swapping vehicle and / or the battery transfer operation between the battery compartments of the battery rack through the telescopic movement of the battery swapping device and the lifting movement of the battery swapping main body. The battery swapping device and the battery swapping main body have the functions of battery disassembly, installation and battery transfer, can ensure the rapid and safe replacement of the battery pack, improve the battery swapping efficiency, and solve at least one aspect of the technical problems existing in the background art.

[0009] The technical solution adopted in this application is as follows:

[0010] A battery swapping station, comprising a battery swapping device, a battery swapping platform and a battery storage device; the battery swapping device is arranged on at least one side of the battery swapping platform along the driving direction of the battery swapping vehicle, and the battery storage device at least comprises a battery storage device arranged on at least one side of the battery swapping device along a direction parallel to the driving direction of the battery swapping vehicle, the battery storage device comprises a battery rack with an opening facing the battery swapping device, and a plurality of battery compartments are sequentially arranged on the battery rack along the vertical direction; the battery swapping device comprises: a fixedly arranged support frame, a battery swapping main body arranged between the support frames and capable of lifting and moving, and a battery swapping device arranged in the battery swapping main body and capable of telescopic movement towards the outside of the support frame, the battery rack shares a column with the support frame or is independently arranged, and the battery disassembly and assembly operation of the battery swapping vehicle and / or the battery transfer operation between the battery compartments of the battery rack are realized through the telescopic movement of the battery swapping device and the lifting movement of the battery swapping main body.

[0011] In this technical solution, the battery swapping platform provides a parking and battery swapping space for battery swapping vehicles, enabling the battery swapping vehicles to park at corresponding battery swapping positions on the platform; the battery storage device is used to temporarily store battery packs, and a charging device can also be installed on the battery rack to meet the charging requirements of discharged batteries during temporary storage; the battery swapping device, as a battery pack transfer structure, is used to perform the interaction work of battery packs between the battery compartment and the battery swapping vehicle, including removing the discharged battery from the battery swapping vehicle and placing it in the battery compartment for temporary storage, and taking out the fully charged battery from the battery compartment and installing it on the battery swapping vehicle. The battery swapping device can be arranged on one side or both sides of the battery swapping platform along the driving direction of the battery swapping vehicle on the platform, so as to achieve single-sided and / or double-sided battery swapping. For example, during double-sided battery swapping, one battery swapping device is used to remove the discharged battery, and the other battery swapping device is used to install the fully charged battery. The battery swapping devices on both sides can perform non-interfering battery swapping actions synchronously, thereby improving the battery swapping efficiency. The opening of the battery rack faces the battery swapping device, and the battery swapping device can directly pick up and place the battery pack in the battery compartment through the opening. The battery rack is sequentially provided with multiple battery compartments vertically, which makes full use of the height space, can accommodate multiple battery packs at the same time, and greatly reduces the floor area when the battery rack accommodates multiple battery packs. The battery swapping main body can move up and down on the support frame to adjust the height of the battery swapping device. When it is necessary to remove the battery pack from the battery swapping vehicle or install the battery pack onto the battery swapping vehicle, the battery swapping device is adjusted to the height position corresponding to the chassis of the battery swapping vehicle by moving the battery swapping main body up and down and then the battery swapping device is extended. When it is necessary to put the discharged battery into the battery compartment for charging or take out the fully charged battery from the battery compartment, the battery swapping device is adjusted to the height corresponding to the battery compartment by moving the battery swapping main body up and down and then the battery swapping device is extended to pick up and place the battery pack, so as to realize the battery disassembly and assembly operation on the battery swapping vehicle and / or the battery transfer operation between the battery compartment of the battery rack. In this application, the battery swapping device is arranged inside the battery swapping main body, so that the battery swapping device extends out of the battery swapping main body to perform the operation of picking up and placing the battery pack. And when actually picking up and placing the battery pack, only the battery swapping device needs to extend out of the battery swapping main body and then enter under the battery swapping vehicle or enter the battery compartment, avoiding the occupation of the space under the vehicle and the space in the battery compartment caused by the whole battery swapping device entering under the battery swapping vehicle and into the battery compartment. Even when the battery swapping vehicle swaps batteries on a battery swapping platform flush with the ground, more operating space can be provided under the vehicle body for the disassembly or installation of the battery pack, making the battery swapping operation more simple and fast, and avoiding the reduction of service life and potential safety hazards brought about by digging the ground under the battery swapping platform to create a sunken space on the ground.The battery rack and the support frame share columns or are independently arranged. When they share columns, the battery transfer distance between the battery rack and the battery swapping device can be shortened, thereby further improving the battery swapping efficiency. At the same time, the device structure can be simplified, the installation space and equipment cost can be saved. Moreover, the columns of the battery rack guide the lifting of the battery swapping body, greatly improving the smoothness of the lifting of the battery swapping body, obtaining the optimal design of the structures of the battery swapping device and the battery rack, reducing the structural complexity, making the overall structure more compact, with higher strength, and saving land resources.

[0012] Preferably, a first battery locking mechanism for locking the battery pack is provided in the battery compartment, and a second battery locking mechanism for locking the battery pack is provided on the battery swapping vehicle. The first battery locking mechanism and the second battery locking mechanism are consistent, so that the battery pack performs the same locking or unlocking operation and battery transfer operation in the battery compartment or on the battery swapping vehicle.

[0013] In this technical solution, the first battery locking mechanism in the battery compartment for locking the battery pack is consistent with the second battery locking mechanism on the battery swapping vehicle for locking the battery pack, making the picking, placing, rotating movements and locking / unlocking movements of the battery pack in the battery compartment by the battery swapping device completely consistent with the picking, placing, rotating movements and locking / unlocking movements under the battery swapping vehicle. This greatly reduces the design burden on the control program and the structural design when the battery transfer equipment realizes the interaction of the battery pack between the battery compartment and the battery swapping vehicle. The same or similar programs can be used to control the same actions, and the same set of battery supporting structure and locking / unlocking structure can be adopted. Moreover, the first battery locking mechanism on the battery rack and the second battery locking mechanism on the battery swapping vehicle are universal due to their consistency, reducing the design cost of the locking mechanism, improving the smoothness and accuracy of battery swapping, shortening the battery swapping time, and enhancing the user's battery swapping experience.

[0014] Preferably, bearing beams for bearing the battery pack are respectively arranged on both sides of the battery compartment along the inlet and outlet direction of the battery pack. The bearing beams are located in the top area of the battery compartment. The first battery locking mechanisms are respectively arranged on the bearing beams. The first battery locking mechanism includes a plurality of lock bases with lock grooves, lock tongues movably arranged in the lock grooves, and a lock link connecting the plurality of lock tongues. The first battery locking mechanism cooperates with a plurality of lock shafts on both sides of the battery pack to suspend and fix the battery pack from both sides.

[0015] In this technical solution, compared with the traditional battery rack that uses two longitudinal beams to carry the battery pack, this solution adopts the first battery locking mechanism in which the battery pack is suspended on the bearing beams on both sides of the top of the battery compartment, enabling the connection between the battery pack and the battery rack to be realized at the top of the battery compartment and the battery pack. On the one hand, there is no need to set longitudinal beams for supporting the battery pack at the bottom of the battery compartment, so that a part of the space can be reserved under the battery pack after it enters the battery compartment to avoid the battery tray of the battery swapping device, and interference of the battery rack with the entry of the battery tray into the battery compartment is avoided. On the other hand, the battery pack is mostly locked in a suspended manner on battery swapping vehicles (especially heavy trucks, light trucks, etc.). Therefore, the battery pack is also locked in a suspended manner within the battery rack, making the battery rack have a greater correlation and better matching degree with the battery swapping vehicle to ensure that the same set of battery swapping equipment performs exactly the same actions for battery interaction between the battery swapping vehicle and the battery rack. Taking the locking of the battery pack as an example, the first battery locking mechanism for locking the battery pack in the battery compartment and the second battery locking mechanism for locking the battery pack on the battery swapping vehicle by the battery swapping equipment both first make the locking shaft enter the vertical opening of the locking groove through the upward movement of the battery swapping main body, and then translate forward into the horizontal opening of the locking groove, so that the locking shaft is limited and locked in the locking groove by the locking tongue.

[0016] Preferably, the battery rack includes two rows of column groups arranged at intervals, and the two rows of column groups are connected by a plurality of longitudinal beams. The battery compartment is formed between the two rows of column groups. Each row of column groups includes two columns spaced along the driving direction of the battery swapping vehicle on the battery swapping platform, and both ends of the bearing beam are connected to the two columns of each row of column groups.

[0017] In this technical solution, the four columns of the two rows of column groups are distributed at the four corners of a rectangle, and the enclosed battery compartment is generally a rectangular space with regular structure, having a good adaptability to the most commonly used rectangular battery packs on the market. The two rows of column groups are connected by a plurality of longitudinal beams, connecting the two column groups into one body, which helps to improve the structural stability. Moreover, both ends of the bearing beam are connected to the two columns of each row of column groups, making the bearing beam not only serve as the connection structure between the two columns of the same column group but also as the support structure for suspending the battery pack, achieving multiple functions with one component. On the basis of improving the structural strength and stability of the battery rack, the structure of the battery rack is simplified, the structural compactness is improved, and more space in the battery compartment is used to accommodate the battery pack, which helps to increase the size of the battery pack as much as possible, thereby increasing the electric energy storage capacity and improving the battery life of the battery swapping vehicle.

[0018] Preferably, the bearing beam includes a square pipe and a first U-shaped plate. The square pipe is connected to the two columns, and the bottom wall of the first U-shaped plate is connected to the side wall of the square pipe facing the battery compartment so that the opening of the first U-shaped plate faces the battery compartment. The plurality of lock bases are arranged on the lower side wall of the first U-shaped plate, and the lock link is located between the upper and lower side walls of the first U-shaped plate to form a moving space for the lock link to drive the lock tongue.

[0019] In this technical solution, the bearing beam is composed of a square pipe and a first U-shaped plate. The square pipe is directly connected to the two columns, and the first U-shaped plate is connected to the square pipe. The superposition of the two structures of the square pipe and the first U-shaped plate not only improves the stability of connecting the two columns together, reduces the risk of the battery rack shaking, but also ensures that the bearing beam itself has relatively high strength, so as to greatly improve the pressure-bearing capacity and reduce the deformation risk in the state of hanging the battery pack. In addition, the internal space of the first U-shaped plate forms a moving space for the lock link to drive the lock tongue, which is convenient for the lock link to move upward to drive the lock tongue to avoid the lock shaft during the unlocking and locking process of the battery pack, so that the lock shaft can enter and exit the lock groove.

[0020] Preferably, the bearing beam includes a second U-shaped plate. The opening surface of the second U-shaped plate faces upward, and both ends of the side wall are respectively connected to the adjacent columns. The side wall of the column facing the battery compartment is connected to the bottom wall and the side walls at both ends of the second U-shaped plate through a plurality of reinforcing rib plates. The plurality of lock bases are arranged on the bottom wall of the second U-shaped plate, and the lock link is located above the bottom wall of the second U-shaped plate to form a moving space for the lock link to drive the lock tongue.

[0021] In this technical solution, the bearing beam is composed of a second U-shaped plate and a plurality of reinforcing ribs. The space above the bottom wall of the second U-shaped plate forms a moving space for the lock link to drive the lock tongue, which is convenient for the lock link to move upward to drive the lock tongue to avoid the lock shaft during the unlocking and locking process of the battery pack, so that the lock shaft can enter and exit the lock groove. One side wall of the second U-shaped plate is connected to the two columns in a large area, which improves the stability of connecting the two columns together and reduces the risk of the battery rack shaking. Moreover, the reinforcing rib plates connect the column to the two side walls and the bottom wall of the second U-shaped plate, and can also ensure that the bearing beam has relatively high structural strength and connection strength, so as to greatly improve the pressure-bearing capacity and reduce the deformation risk in the state of hanging the battery pack.

[0022] Preferably, the battery rack includes two mounting beams provided on the back surface on the side opposite to the opening. The two mounting beams are arranged vertically and are fixedly connected to the column group through the longitudinal beam; the battery swapping station further includes an electrical connection device provided in the battery compartment. The electrical connection device is arranged between the two mounting beams and its interface end faces the opening of the battery compartment; when the battery pack moves to be locked with the first battery locking mechanism, the electrical connection port of the battery pack is electrically connected to the interface end of the electrical connection device.

[0023] In this technical solution, on the one hand, two mounting beams connect multiple longitudinal beams on the back of the battery rack together, playing a role in structural strengthening and further enhancing the structural stability of the battery rack. On the other hand, an installation space for the electrical connection device is formed between the two mounting beams, and the installation and bearing of the electrical connection device are realized, optimizing the installation layout of the electrical connection device on the battery rack. When the battery pack moves to be locked with the first battery locking mechanism, the electrical connection port of the battery pack is exactly electrically connected to the interface end of the electrical connection device. In other words, the locking action of the battery pack in the battery compartment is synchronously completed with the action of electrically connecting the electrical connection device. Of course, the unlocking action of the battery pack in the battery compartment is also synchronously completed with the action of disconnecting from the electrical connection device, making the battery swapping device the direct executing mechanism for operating the connection between the battery pack and the electrical connection device, eliminating the existing step of manually plugging in for charging after the battery pack is sent into the battery compartment, making the interaction of the battery pack in the battery compartment more automated, saving manpower, and improving efficiency.

[0024] Preferably, the battery swapping station further includes a counterweight unit disposed on the other side of the battery rack relative to the battery swapping device, and the counterweight unit includes two counterweight blocks slidably connected to both sides of the electrical connection device.

[0025] In this technical solution, the two counterweight blocks are arranged on both sides of the electrical connection device and are overall located on the back side of the battery rack. On the one hand, the counterweight blocks can counterweight the battery rack, increasing the overall weight of the battery storage device, and thus enhancing the standing stability of the battery rack on the ground. On the other hand, the counterweight blocks are slidably arranged. Therefore, in a preferred embodiment, the counterweight blocks can also counterweight the battery swapping main body as a balance structure for the lifting of the battery swapping main body. When the battery swapping main body rises, the counterweight blocks descend, and when the battery swapping main body descends, the counterweight blocks rise, improving the lifting stability of the battery swapping main body.

[0026] Preferably, along the direction parallel to the driving direction of the battery swapping vehicle on the battery swapping platform, battery storage devices are provided on both the front and rear sides of the battery swapping device, and the battery storage devices located on the front and rear sides of the battery swapping device are symmetrically arranged with respect to the battery swapping device; and / or, a battery storage device is provided on the other side of the battery swapping device opposite to the battery swapping platform.

[0027] In this technical solution, battery storage devices can be arranged on both the front and rear sides of the battery swapping device and on the other side opposite to the battery swapping platform, which can further utilize the installation space around the battery swapping device, increase the battery storage space and the number of available batteries in the battery swapping station, effectively utilize the space in the battery swapping station, and increase the battery swapping scale of the battery swapping station.

[0028] Preferably, the battery swapping body is connected to the support frame through a moving component, and the battery swapping body is rotatably connected to the moving component. By rotating the battery swapping body, the orientation of the battery swapping device can be adjusted to facilitate telescopic movement for battery disassembly and assembly operations and / or battery transfer operations.

[0029] In this technical solution, by setting a moving component to drive the battery swapping body to move up and down along the support frame, the height of the battery swapping device can be adjusted. At the same time, the battery swapping body is rotatably connected to the moving component, which is convenient for adjusting the angle of the battery swapping body, thereby adjusting the angle at which the battery swapping device extends. When the position of the battery to be transferred is deflected, accurate positioning and extension can be achieved through rotational adjustment, effectively transferring the battery. Moreover, the rotatability of the battery swapping body makes the layout of the battery storage device more flexible and more scalable. When the battery racks are arranged around the periphery of the battery swapping device, the rotation of the battery swapping body enables the battery swapping device to interact with the battery racks at any position, improving the battery transfer efficiency.

[0030] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows: The battery swapping platform provides a parking and battery swapping space for battery swapping vehicles, enabling the battery swapping vehicles to park at corresponding battery swapping positions on the battery swapping platform; the battery storage device is used to temporarily store battery packs, and a charging device can also be installed on the battery rack to meet the charging requirements of discharged batteries during temporary storage; the battery swapping device serves as a transfer structure and is used to perform the interaction work of battery packs between the battery compartment and the battery swapping vehicle, including removing the discharged battery from the battery swapping vehicle and placing it in the battery compartment for temporary storage, and taking out the fully charged battery from the battery compartment and installing it on the battery swapping vehicle. The battery swapping device can be arranged on one side or both sides of the battery swapping platform along the driving direction of the battery swapping vehicle on the battery swapping platform, so that single-sided and / or double-sided battery swapping can be achieved. For example, during double-sided battery swapping, the battery swapping device on one side is used to disassemble the discharged battery, and the battery swapping device on the other side is used to install the fully charged battery. The battery swapping devices on both sides can perform non-interfering battery swapping operations synchronously, thereby improving the battery swapping efficiency. The opening of the battery rack faces the battery swapping device, and the battery swapping device can directly pick up and place the battery pack in the battery compartment through the opening. The battery rack is provided with a plurality of battery compartments arranged vertically in sequence, which makes full use of the height space and can accommodate multiple battery packs at the same time, greatly reducing the floor area of the battery rack. The battery swapping main body can move up and down on the support frame to adjust the height of the battery swapping device. When it is necessary to disassemble the battery pack from the battery swapping vehicle or install the battery pack onto the battery swapping vehicle, the battery swapping device is adjusted to the height position corresponding to the chassis of the battery swapping vehicle by moving the battery swapping main body up and down and then the battery swapping device is extended. When it is necessary to put the discharged battery into the battery compartment for charging or take out the fully charged battery from the battery compartment, the battery swapping device is adjusted to the height corresponding to the battery compartment by moving the battery swapping main body up and down and then the battery swapping device is extended to pick up and place the battery pack, thereby realizing the battery disassembly and installation operation for the battery swapping vehicle and / or the battery transfer operation between the battery compartment of the battery rack. In this application, the battery swapping device is arranged inside the battery swapping main body, so that the battery swapping device extends out of the battery swapping main body to perform the operation of picking up and placing the battery pack. And when specifically picking up and placing the battery pack, only the battery swapping device needs to extend out of the battery swapping main body and then enter below the battery swapping vehicle or enter the battery compartment, avoiding the occupation of the space under the vehicle bottom and the space inside the battery compartment caused by the whole battery swapping device entering under the battery swapping vehicle and inside the battery compartment. Even when the battery swapping vehicle swaps batteries on the battery swapping platform flush with the ground, more operating space can be provided under the vehicle body for the disassembly or installation of the battery pack, making the battery swapping operation simpler and faster, and effectively avoiding the reduction of service life and potential safety hazards brought about by digging a sunken space under the battery swapping platform to create a ground subsidence space.The battery rack and the support frame share columns or are independently arranged. When they share columns, the battery transfer distance between the battery rack and the battery swapping device can be shortened, thereby further improving the battery swapping efficiency. At the same time, the equipment structure can be simplified, the installation space and equipment cost can be saved. Moreover, the columns of the battery rack guide the lifting of the battery swapping body, greatly improving the smoothness of the lifting of the battery swapping body, obtaining the optimal design of the structures of the battery swapping device and the battery rack, reducing the structural complexity, making the overall structure more compact, with higher strength, and saving land resources.

The battery storage device 3 includes a battery rack 31 with an opening facing the battery swapping device 1, and a plurality of battery compartments 32 are sequentially arranged vertically on the battery rack 31; the battery swapping device 1 includes: a support frame 11 fixedly arranged, a battery swapping main body 12 disposed between the support frames 11 and capable of lifting and moving, and a battery swapping device 13 disposed inside the battery swapping main body 12 and capable of telescoping and moving outside the support frame 11. The battery rack 31 shares a column 311 with the support frame 11 or is independently arranged, and the battery disassembly and assembly operation on the battery swapping vehicle and / or the battery transfer operation between the battery compartments 32 of the battery rack 31 are realized through the telescoping movement of the battery swapping device 13 and the lifting movement of the battery swapping main body 12.

[0054] In this technical solution, the battery swapping platform 2 provides a parking and battery swapping space for battery swapping vehicles. The battery swapping vehicles can drive into from one end of the battery swapping platform and then park at the corresponding battery swapping position. At this battery swapping position, the battery swapping device 1 can perform the battery pack replacement operation. The battery storage device is used to temporarily store the battery packs, and a charging device can also be installed on the battery rack 31 to meet the charging requirements when the discharged batteries are temporarily stored. After being fully charged, it is prepared for the battery swapping device 1 to reinstall on the battery swapping vehicle. The battery swapping device 1 serves as a battery pack transfer structure and is used to perform the interaction work of the battery pack between the battery compartment 32 and the battery swapping vehicle, including removing the discharged battery from the battery swapping vehicle and placing it in the battery compartment 32 for temporary storage, and taking out the fully charged battery from the battery compartment 32 and installing it on the battery swapping vehicle.

[0055] The battery swapping device 1 can be arranged on one side or both sides of the battery swapping platform 2 along the driving direction of the battery swapping vehicle on the battery swapping platform 2, so as to achieve single-sided and / or double-sided battery swapping. Figure 1 An embodiment in which the battery swapping device 1 is arranged on one side of the battery swapping platform 2 is illustrated, realizing single-sided battery swapping. Figure 2 An embodiment in which the battery swapping device 1 is arranged on both sides of the battery swapping platform 2 is illustrated. The battery swapping device 1 on one side is used to disassemble the discharged battery, and the battery swapping device 1 on the other side is used to install the fully charged battery. The battery swapping devices 1 on both sides can synchronously perform non-interfering battery swapping actions, thereby improving the battery swapping efficiency.

[0056] The opening of the battery rack 31 faces the battery swapping device 1, and the battery swapping device 1 can directly take and place the battery pack in the battery compartment 32 through the opening. A plurality of battery compartments 32 are sequentially arranged vertically on the battery rack 31. It makes full use of the height space and can accommodate multiple battery packs at the same time, greatly reducing the floor area when the battery rack 31 accommodates multiple battery packs. The battery swapping main body 12 can move up and down on the support frame 11 to adjust the height of the battery swapping device 1. When it is necessary to disassemble the battery pack from the battery swapping vehicle or install the battery pack on the battery swapping vehicle, the battery swapping device 1 is adjusted to the height position corresponding to the chassis of the battery swapping vehicle by moving the battery swapping main body 12 up and down, and then the battery swapping device 1 is extended. When it is necessary to put the discharged battery into the battery compartment 32 for charging or take out the fully charged battery from the battery compartment 32, the battery swapping device 1 is adjusted to the height corresponding to the battery compartment 32 by moving the battery swapping main body 12 up and down, and then the battery swapping device 1 is extended to take and place the battery pack, so as to realize the battery disassembly and assembly operation on the battery swapping vehicle and / or the battery transfer operation between the battery compartment 32 of the battery rack 31.

[0057] In this application, the battery swapping device 13 is arranged inside the battery swapping main body 12, so that the battery swapping device 13 extends out of the battery swapping main body 12 to perform the operation of taking and placing the battery pack. And when actually taking and placing the battery pack, it only needs the battery swapping device 13 to extend out of the battery swapping main body 12 and then enter under the battery swapping vehicle or enter the battery compartment 32, avoiding the occupation of the space under the vehicle bottom and the space inside the battery compartment 32 caused by the whole battery swapping equipment 1 entering under the battery swapping vehicle bottom and inside the battery compartment 32. Even when the battery swapping vehicle is swapping batteries on the battery swapping platform 2 flush with the ground, more operating space can be provided under its vehicle body for the disassembly or installation of the battery pack, making the battery swapping operation more convenient and fast, and avoiding the reduction of service life and potential safety hazards brought by excavating the ground under the battery swapping platform 2 to create a sunken space on the ground. The battery rack 31 shares the upright columns 311 with the support frame 11 or is independently arranged with each other. Figures 1 to 4 The embodiment shown is where the battery rack 31 shares the upright columns 311 with the support frame 11. This design can shorten the battery transfer distance between the battery rack 31 and the battery swapping equipment 1, thereby further improving the battery swapping efficiency. At the same time, it can also simplify the equipment structure, save the installation space and equipment cost. Moreover, the upright columns 311 of the battery rack 31 guide the lifting of the battery swapping main body 12, greatly improving the smoothness of the lifting of the battery swapping main body 12, obtaining the optimal design of the structures of the battery swapping equipment 1 and the battery rack 31, reducing the structural complexity, making the overall structure more compact, with higher strength, and saving land resources. Specifically, as Figure 3 and Figure 4 shown, in the embodiment where a battery storage device 3 is provided on each side of the battery swapping equipment 1, the adjacent four upright columns 311 of the battery racks 31 on both sides form a fixedly arranged support frame 11, and the battery swapping main body 12 moves up and down along these four upright columns 311. Figure 13 The embodiment shown is where the battery rack 31 and the support frame 11 are independently arranged. At this time, there is a spacing between the battery rack 31 and the support frame 11.

[0058] Regarding the way for the battery swapping device 13 to achieve telescopic movement, in a preferred embodiment, as Figures 3 to 5 shown, the battery swapping device 13 can further include a telescopic mechanism 131. The telescopic mechanism 131 can be selected as a forklift. By the telescopic mechanism 131 telescoping relative to the battery swapping main body 12, structures such as a battery tray 132 for carrying the battery pack and an unlocking pin 133 for unlocking and locking the battery pack can be arranged on the telescopic mechanism 131. When the telescopic mechanism 131 extends towards the battery swapping vehicle on the battery swapping platform 2, the battery tray 132 is sent under the battery swapping vehicle to perform unlocking, locking, disassembly, and transfer of the battery pack. When the telescopic mechanism 131 extends towards the battery rack 31, the battery tray 132 is sent into the battery compartment 32 to perform unlocking, locking, disassembly, and transfer of the battery pack.

[0059] As a preferred embodiment of the present application, a first battery locking mechanism 33 for locking the battery pack is provided in the battery compartment 32, and the battery swapping vehicle is provided with a second battery locking mechanism for locking the battery pack. The first battery locking mechanism 33 and the second battery locking mechanism are consistent, so that the battery pack performs the same locking or unlocking operations and battery transfer operations in the battery compartment 32 or on the battery swapping vehicle. Figure 3 , Figure 4 , Figure 5 and Figure 7 illustrate an embodiment in which the first battery locking mechanism 33 is provided in the battery compartment 32. The battery swapping vehicle and the second battery locking mechanism are not illustrated in the drawings, but only the first battery locking mechanism 33 and the second battery locking mechanism need to be made consistent. Those skilled in the art can understand that by making the first battery locking mechanism 33 and the second battery locking mechanism consistent, the pick-up, placement, rotation movements and locking / unlocking actions of the battery swapping device 13 on the battery pack in the battery compartment 32 are completely the same as those on the battery swapping vehicle, greatly reducing the design burden of the control program and the structural design when the battery transfer device realizes the battery pack interaction between the battery compartment 32 and the battery swapping vehicle. The same or similar programs can be used to control the same actions, and the same set of battery support structures and locking / unlocking structures can be adopted, such as using the same battery tray 132 and the unlocking pin 133 on the battery tray 132. The first battery locking mechanism 33 on the battery rack 31 and the second battery locking mechanism on the battery swapping vehicle are universal because they are consistent, reducing the design cost of the locking mechanism, improving the smoothness and accuracy of battery swapping, shortening the battery swapping time, and enhancing the user's battery swapping experience.

[0060] Further preferably, as Figures 6 to 11As shown in the figure, on both sides of the battery compartment 32 along the inlet and outlet direction of the battery pack, there are bearing beams 312 for carrying the battery pack respectively. The bearing beams 312 are located in the top area of the battery compartment 32. The first battery locking mechanism 33 is provided on the bearing beams 312 one by one. The first battery locking mechanism 33 includes a plurality of locking bases 331 with locking grooves 3311, locking tongues 332 that can be movably arranged in the locking grooves 3311, and a locking link 333 connecting the plurality of locking tongues 332. The first battery locking mechanism 33 cooperates with a plurality of locking shafts on both sides of the battery pack to suspend and fix the battery pack from both sides. Specifically, the locking bases 331 on each bearing beam 312 can be arranged at intervals along the inlet and outlet direction of the battery pack. The same side of the battery pack is suspended and locked by a plurality of locking bases 331 to avoid stress concentration and improve the suspension and locking stability of the battery pack in the battery compartment 32. The first battery locking mechanism 33 includes a plurality of locking bases 331, and one locking tongue 332 is correspondingly arranged in each locking base 331. All the locking tongues 332 on the same bearing beam 312 are connected by the locking link 333. The locking tongue 332 is used to open or close the locking groove 3311. When locking the battery pack, since the locking shaft on the battery pack needs to enter the locking groove 3311, the locking link 333 can be pushed to drive all the locking tongues 332 to move upward to open the locking groove 3311, so that the locking shaft can enter the locking groove 3311. Then, the pushing of the locking link 333 is cancelled, and the locking link 333 drives the locking tongue 332 to move downward to re-close the locking groove 3311. At this time, the locking tongue 332 blocks the locking shaft from disengaging from the locking groove 3311, thus realizing the locking of the battery pack; when unlocking the battery pack, since the locking shaft on the battery pack needs to disengage from the locking groove 3311, the locking link 333 can be pushed to drive all the locking tongues 332 to move upward to open the locking groove 3311, so that the locking shaft can disengage from the locking groove 3311. After the locking shaft disengages from the locking groove 3311, the pushing of the locking link 333 is cancelled, and the locking link 333 drives the locking tongue 332 to move downward to re-close the locking groove 3311.Those skilled in the art can understand that, compared with the traditional battery rack 31 that uses two longitudinal beams to carry the battery pack, in this solution, the battery pack is suspended on the first battery locking mechanism 33 on the bearing beams 312 on both sides of the top of the battery compartment 32, so that the connection between the battery pack and the battery rack 31 is realized at the top of the battery compartment 32 and the battery pack. On the one hand, there is no need to set longitudinal beams for supporting the battery pack at the bottom of the battery compartment 32, so that a part of the space can be reserved below the battery pack after it enters the battery compartment 32 to avoid the battery tray 132 of the battery swapping device 13, and the interference of the battery rack 31 to the entry of the battery tray 132 into the battery compartment 32 is avoided. On the other hand, for the solution in which the battery pack is locked by hanging on the battery swapping vehicle (especially heavy trucks, light trucks, etc.), in this application, the battery pack is also locked by hanging in the battery rack 31, so that a greater correlation and better matching degree are formed between the battery rack 31 and the battery swapping vehicle, so as to ensure that the same set of battery swapping equipment 1 performs exactly the same actions for the battery interaction between the battery swapping vehicle and the battery rack 31. Taking the locking of the battery pack as an example, the battery swapping equipment 1 locks the battery pack to the first battery locking mechanism 33 of the battery compartment 32 and the second battery locking mechanism that locks to the battery swapping vehicle. Both are pre-set to make the locking shaft enter the vertical opening of the locking groove through the upward movement of the battery swapping main body 12, then translate forward into the locking groove, and then limit and lock the locking shaft in the locking groove through the locking tongue.

[0061] Regarding the specific structure of the battery rack 31, in a preferred embodiment, such as Figure 8 and Figure 9As shown in the figure, the battery rack 31 includes two rows of column groups arranged at intervals. The two rows of column groups are connected by a plurality of longitudinal beams 313. The battery compartment 32 is formed between the two rows of column groups. Each row of column groups includes two columns 311 spaced along the driving direction of the battery swapping vehicle on the battery swapping platform 2. Both ends of the bearing beam 312 are connected to the two columns 311 of each row of column groups. In this technical solution, the four columns 311 of the two rows of column groups are distributed at the four corners of a rectangle, and the enclosed battery compartment 32 is generally a rectangular space with regular structure, which has good adaptability to the most commonly used rectangular battery packs on the market. The two rows of column groups are connected by a plurality of longitudinal beams 313, so that the two column groups are connected into one body, which helps to improve the structural stability. Moreover, both ends of the bearing beam 312 are connected to the two columns 311 of each row of column groups, so that the bearing beam 312 not only serves as a connecting structure for the two columns 311 of the same column group, but also serves as a supporting structure for hanging the battery pack, realizing multiple functions with one component. On the basis of improving the structural strength and stability of the battery rack 31, the structure of the battery rack 31 is simplified, the structural compactness is improved, more space in the battery compartment 32 is used to accommodate the battery pack, which helps to increase the size of the battery pack as much as possible, so as to increase the electric energy storage capacity and improve the cruising range of the battery swapping vehicle. Preferably, the columns 311 and the longitudinal beams 313 can be connected by welding and / or bolts, and the bearing beam 312 and the columns 311 can also be connected by welding and / or bolts to improve the connection strength.

[0062] Regarding the specific structure of the bearing beam 312, the present application does not make any limitations, and it includes at least the following two embodiments:

[0063] Embodiment 1: As Figure 10As shown in the figure, the bearing beam 312 includes a square tube 3121 and a first U-shaped plate 3122. The square tube 3121 is connected to two columns 311. The bottom wall of the first U-shaped plate 3122 is connected to the side wall of the square tube 3121 facing the battery compartment 32 so that the opening of the first U-shaped plate 3122 faces the battery compartment 32. A plurality of lock bases 331 are provided on the lower side wall of the first U-shaped plate 3122. The lock link 333 is located between the upper and lower side walls of the first U-shaped plate 3122 to form a moving space for the lock link 333 to drive the lock tongue 332. In this technical solution, the bearing beam 312 is composed of two parts: a square tube 3121 and a first U-shaped plate 3122. The square tube 3121 is directly connected to two columns 311, and the first U-shaped plate 3122 is connected to the square tube 3121. The superposition of the two structures of the square tube 3121 and the first U-shaped plate 3122 not only improves the stability of connecting the two columns 311 together, reduces the risk of the battery rack 31 shaking, but also ensures that the bearing beam 312 itself has relatively high strength, so as to greatly improve the pressure-bearing capacity and reduce the deformation risk in the state of hanging the battery pack. In addition, the internal space of the first U-shaped plate 3122 forms a moving space for the lock link 333 to drive the lock tongue 332, which is convenient for the lock link 333 to move upward to drive the lock tongue 332 to avoid the lock shaft during the locking and unlocking process of the battery pack, so that the lock shaft can enter and exit the lock groove 3311. The bottom walls of the square tube 3121 and the first U-shaped plate 3122 are preferably connected by welding, with high connection strength and not easy to deform and loosen.

[0064] Embodiment 2: As Figure 11As shown in the figure, the bearing beam 312 includes a second U-shaped plate 3123. The opening surface of the second U-shaped plate 3123 faces upward, and both ends of the side walls are respectively connected to the adjacent columns 311. The side wall of the column 311 facing the battery compartment 32 is connected to the bottom wall and the side walls at both ends of the second U-shaped plate 3123 through a plurality of reinforcing rib plates 3124. A plurality of lock bases 331 are arranged on the bottom wall of the second U-shaped plate 3123. The lock link 333 is located above the bottom wall of the second U-shaped plate 3123 to form a moving space for the lock link 333 to drive the lock tongue 332. In this technical solution, the bearing beam 312 is composed of the second U-shaped plate 3123 and a plurality of reinforcing ribs. The space above the bottom wall of the second U-shaped plate 3123 forms a moving space for the lock link 333 to drive the lock tongue 332, which facilitates the upward movement of the lock link 333 to drive the lock tongue 332 to avoid the lock shaft during the locking and unlocking process of the battery pack, so that the lock shaft can enter and exit the lock slot 3311. One side wall of the second U-shaped plate 3123 is connected to the two columns 311 over a large area, improving the stability of connecting the two columns 311 together and reducing the risk of shaking of the battery rack 31. Moreover, the reinforcing rib plates 3124 connect the column 311 to the two side walls and the bottom wall of the second U-shaped plate 3123, which can ensure that the bearing beam 312 has relatively high structural strength and connection strength, so as to greatly improve the pressure-bearing capacity and reduce the deformation risk in the state of suspending the battery pack. The side wall of the second U-shaped plate 3123 and the column 311 are preferably connected by welding, and the column 311, the reinforcing rib plate 3124 and the second U-shaped plate 3123 are also preferably connected by welding, with high connection strength and not easy to deform and loosen.

[0065] Regarding the structure of the battery storage device 3, in a preferred embodiment, as Figures 6 to 9As shown, the battery rack 31 includes two mounting beams 314 disposed on the back side opposite to the opening. The two mounting beams 314 are arranged vertically and are fixedly connected to the column group through a longitudinal beam 313. The battery swapping station further includes an electrical connection device 34 disposed in the battery compartment 32. The electrical connection device 34 is disposed between the two mounting beams 314 and its interface end 341 faces the opening of the battery compartment 32. When the battery pack moves to be locked with the first battery locking mechanism 33, the electrical connection port of the battery pack is electrically connected to the interface end 341 of the electrical connection device 34. In this technical solution, on the one hand, the two mounting beams 314 connect multiple longitudinal beams 313 on the back of the battery rack 31 together, playing a role in structural strengthening and further enhancing the structural stability of the battery rack 31. On the other hand, the space enclosed between the two mounting beams 314 serves as the installation space for the electrical connection device 34 and realizes the installation and bearing of the electrical connection device 34, optimizing the installation layout of the electrical connection device 34 on the battery rack 31. When the battery pack moves to be locked with the first battery locking mechanism 33, the electrical connection port of the battery pack is exactly electrically connected to the interface end 341 of the electrical connection device 34. In other words, the locking action of the battery pack in the battery compartment 32 is synchronously completed with the action of electrically connecting to the electrical connection device 34. Of course, the unlocking action of the battery pack in the battery compartment 32 is also synchronously completed with the action of disconnecting from the electrical connection device 34, making the battery swapping device 13 the direct executing mechanism for operating the connection between the battery pack and the electrical connection device 34, eliminating the step of manually inserting the power plug for charging after the battery pack is sent into the battery compartment in the prior art, making the interaction of the battery pack in the battery compartment 32 more automated, saving manpower and improving efficiency.

[0066] Further preferably, as Figure 7 and Figure 9 shown, the battery swapping station further includes a counterweight unit disposed on the other side of the battery rack 31 relative to the battery swapping device 1. The counterweight unit includes two counterweight blocks 35 slidably connected to both sides of the electrical connection device 34. In this technical solution, the two counterweight blocks 35 are arranged on both sides of the electrical connection device 34 and are overall located on the back side of the battery rack 31. On the one hand, the counterweight blocks 35 can counterweight the battery rack 31, increasing the overall weight of the battery storage device, and further enhancing the standing stability of the battery rack 31 on the ground. On the other hand, the counterweight blocks 35 are slidably arranged. Therefore, in a preferred embodiment, the counterweight blocks 35 can also counterweight the battery swapping main body 12 and serve as a balance structure for the lifting of the battery swapping main body 12. When the battery swapping main body 12 rises, the counterweight blocks 35 descend, and when the battery swapping main body 12 descends, the counterweight blocks 35 rise, improving the lifting stability of the battery swapping main body 12. Specifically, guide rails 315 for the counterweight blocks 35 to slide up and down can be provided on the back side of the battery rack 31. One guide rail 315 is provided on both sides of each counterweight block 35, and the counterweight blocks 35 are slidably connected to the guide rails 315 on both sides.

[0067] As a preferred implementation manner of the present application, asFigures 1 to 4 As shown, along the direction parallel to the traveling direction of the battery swapping vehicle on the battery swapping platform 2, battery storage devices 3 are provided on both the front and rear sides of the battery swapping device 1, and the battery storage devices 3 on the front and rear sides of the battery swapping device 1 are symmetrically arranged with respect to the battery swapping device 1. As another preferred embodiment of the present application, a battery storage device 3 is provided on the other side of the battery swapping device 1 opposite to the battery swapping platform 2. Figure 14 The above battery swapping station is illustrated in [FIGURE] to adopt both of the above two preferred embodiments, that is, battery storage devices 3 are provided on both the front and rear sides of the battery swapping device 1 and on the other side opposite to the battery swapping platform 2, which can further utilize the installation space around the battery swapping device 1, increase the battery storage space and the number of available batteries in the battery swapping station, effectively utilize the space in the battery swapping station, and increase the battery swapping scale of the battery swapping station. Moreover, during specific operation, fully charged batteries can be transported to the battery rack 31 closer to the battery swapping device 1 for convenient and quick access, while discharged batteries are transported to the battery rack 31 farther from the battery swapping device 1 for charging and standby. This makes the management and allocation of fully charged batteries and discharged batteries in the entire battery swapping station more reasonable, thus facilitating further improvement of the battery swapping efficiency. In this embodiment, the extending direction of the telescopic mechanism 131 towards the battery swapping platform 2 and the extending directions towards each battery rack 31 are basically perpendicular to each other in pairs. Of course, in other embodiments, each battery rack 31 and the battery swapping platform 2 can also be arranged in more different layout manners such as a pentagon or a hexagon on the periphery of the battery swapping device 1.

[0068] Further preferably, as Figure 3 , Figure 4 and Figure 14As shown in the figure, the battery swapping body 12 is connected to the support frame 11 through the moving component 4, and the battery swapping body 12 is rotatably connected to the moving component 4. By rotating the battery swapping body 12, the orientation of the battery swapping device 13 can be adjusted to facilitate telescopic movement for performing battery disassembly and assembly operations and / or battery transfer operations. Specifically, the moving component 4 can be a frame structure with rollers 41. The battery swapping body 12 is rotatably connected to the bottom of the frame structure. The frame structure realizes lifting movement by rolling along the support frame 11 through the rollers 41. In the embodiment where the battery rack 31 and the support frame 11 share the column 311, the frame structure realizes lifting movement by rolling along the column 311 of the battery rack 31 through the rollers 41. In a preferred embodiment, the battery swapping body 12 can be rotatably connected to the moving component 4 through a driving motor and a gear mechanism. The gear mechanism includes a driving gear and a driven gear. The driving motor is fixed to the moving component 4. The driving gear is connected to the output shaft of the driving motor. The driving gear and the driven gear are meshed. The driven gear is fixed to the battery swapping body 12. In this technical solution, by setting the moving component 4 to drive the battery swapping body 12 to move up and down along the support frame 11, the height of the battery swapping device 13 can be adjusted. At the same time, the battery swapping body 12 and the moving component 4 are rotatably connected, which is convenient for adjusting the angle of the battery swapping body 12, thereby adjusting the extending angle of the battery swapping device 13. When the position of the battery to be transferred has a deflection angle, accurate positioning and extension can be achieved through rotational adjustment, effectively transferring the battery. Moreover, the rotatability of the battery swapping body 12 makes the layout of the battery storage device 3 more flexible and has stronger scalability. When the battery racks 31 are arranged around the periphery of the battery swapping device 1, the battery swapping device 13 can interact with the battery racks 31 at any position through the rotation of the battery swapping body 12, improving the battery transfer efficiency.
