Description

[0001] This application claims priority to Chinese patent application No. 202410380046.4, filed on March 29, 2024. This application incorporates the entirety of the aforementioned patent application. Technical Field

[0002] The present application relates to the technical field of battery replacement for electric vehicles, and in particular to a battery replacement station. Background Art

[0003] With the development and popularization of new energy vehicles, battery pack quick-swap technology has also developed rapidly. For large vehicles, such as heavy trucks and light trucks, the heavy weight of the body and cargo leads to higher battery pack capacity requirements, requiring a sufficiently large capacity of electricity to support the operation of large vehicles.

[0004] In traditional battery swapping, large new energy vehicles use a top-lift method to secure large battery containers to the vehicle's beams. These containers are located close to the cab, posing significant safety risks to both the driver and the vehicle during operation and during top-lift battery swapping. Furthermore, battery failures can directly harm the driver. Furthermore, the top-lift method places high demands on the site for battery swap stations, requiring sufficient space for lifting equipment to transport and store batteries, resulting in high construction costs.

[0005] Therefore, for large vehicles, there is an urgent need for a safer, more reliable and easy-to-popularize battery swap mode. For example, a chassis-type battery swap mode for passenger cars is adopted. In the chassis-type battery swap mode, it is necessary to control the battery swap equipment to move as a whole to the battery swap position under the battery swap vehicle, and then perform lifting operations and remove or install battery pack operations to complete the entire battery swap process. In this battery swap process, due to the limited space under the body of the battery swap vehicle, especially heavy-duty battery swap vehicles that are difficult to drive and park on platforms above the ground, the space under the body of the battery swap vehicle is even more limited. If a battery swap device is used for battery swapping, the battery swap device needs to carry the depleted battery or the fully charged battery back and forth and in and out of the bottom of the battery swap vehicle during the battery swap process. In order to meet the power requirements of heavy-duty battery swap vehicles, the battery packs are very large, which leads to a great restriction on the available space for the battery swap equipment. At this time, if you want to increase the available space for the battery swapping equipment, you can only move the battery swapping equipment in the space sunken from the ground. Due to the multiple driving of heavy-duty battery swapping vehicles before and after battery swapping, the ground structure under this method will inevitably become unreliable and difficult to bear the multiple loads of the battery swapping vehicles, reducing the life of the equipment structure and posing a safety hazard to the battery swapping vehicles.

[0006] In addition, a battery swap station is usually equipped with a battery rack that can carry multiple battery packs. The battery rack is equipped with many battery compartments that can temporarily store battery packs. The depleted batteries removed from the battery swap vehicle need to be sent to the battery compartment for storage and charging. At the same time, the fully charged batteries to be installed on the battery swap vehicle need to be obtained from the battery rack. Therefore, the battery transfer equipment needs to use the battery tray and unlocking pin to unlock the depleted batteries on the battery swap vehicle and transfer them to the battery compartment for charging, and take out the fully charged batteries in the battery compartment and install and lock them on the battery swap vehicle. For the chassis-type battery swap mode, the more popular method currently is to hang the battery pack on the chassis of the battery swap 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 low-power batteries sent into the battery compartment are usually supported by the supporting structure at the bottom of the battery compartment. Therefore, it is necessary to set space on the supporting structure to avoid the battery tray, which brings difficulties to the design of the supporting structure. Therefore, the battery rack mostly supports the battery pack through two longitudinal beams, and the battery tray enters the battery compartment from between the two longitudinal beams, but the load-bearing stability of the two longitudinal beams is poor and the safety risk is high. Furthermore, since the installation method of the battery pack on the battery swap vehicle is different from the storage method in the battery compartment, the burden of the battery transfer equipment in exchanging battery packs between the battery compartment and the battery swap vehicle is increased, and the battery swap efficiency is low.

[0007] This shows that the many drawbacks of the prior art need to be further improved and enhanced. Summary of the Invention

[0008] The present application provides a battery swap station, which realizes battery disassembly and assembly operations on battery swap vehicles and / or battery transfer operations between battery compartments of battery racks through the telescopic movement of the battery swap device and the lifting and lowering movement of the battery swap body. The battery swap device and the battery swap body have both battery disassembly, installation and battery transfer functions, which can ensure the rapid and safe replacement of battery packs, improve the battery swap efficiency, and solve at least one technical problem existing in the background technology.

[0009] The technical solutions adopted in this application are:

[0010] A battery swap station comprises a battery swap device, a battery swap platform and a battery storage device; the battery swap device is arranged on at least one side of the battery swap platform along the driving direction of the battery swap vehicle, and the battery storage device at least comprises a battery storage device arranged on at least one side of the battery swap device in a direction parallel to the driving direction of the battery swap vehicle, and the battery storage device comprises a battery rack with an opening facing the battery swap device, and the battery rack is vertically arranged in sequence with multiple battery compartments; the battery swap equipment comprises: a fixed support frame, a battery swap body arranged between the support frames and movable by lifting and lowering, and a battery swap device arranged in the battery swap body and telescopically movable to the outside of the support frame, the battery rack and the support frame share a column or are arranged independently of each other, and the battery disassembly and assembly operations of the battery swap vehicle and / or the battery transfer operations between the battery compartments of the battery rack are realized through the telescopic movement of the battery swap device and the lifting and lowering movement of the battery swap body.

[0011] In the technical solution, the battery replacement platform provides a parking space for the battery replacement vehicle to park at a corresponding battery replacement position; the battery storage device is used for temporarily storing battery packs and can also be provided with a charging device on the battery rack to meet the charging needs of the temporarily stored battery packs; the battery replacement equipment serves as a battery pack transfer structure and is used for performing the interaction between the battery pack and the battery replacement vehicle, including the work of taking the depleted battery off the battery replacement vehicle and storing it in the battery compartment and the work of taking the fully charged battery out of the battery compartment and installing it on the battery replacement vehicle. The battery replacement equipment can be arranged on one side or both sides of the battery replacement platform along the driving direction of the battery replacement vehicle on the battery replacement platform, so that one-sided and / or two-sided battery replacement can be realized. For example, in two-sided battery replacement, the battery replacement equipment on one side is used for disassembling the depleted battery, and the battery replacement equipment on the other side is used for installing the fully charged battery. The battery replacement equipment on both sides can synchronously perform the battery replacement actions without interfering with each other, thereby improving the battery replacement efficiency. The opening of the battery rack faces the battery replacement equipment, and the battery replacement equipment can directly take and place the battery pack in the battery compartment through the opening. The battery rack is sequentially provided with a plurality of battery compartments in the vertical direction, which fully utilizes the height space and can simultaneously accommodate a plurality of battery packs, greatly reducing the floor area when the battery rack accommodates a plurality of battery packs. The battery replacement main body is movably lifted on the support frame to adjust the height of the battery replacement device. When it is necessary to disassemble the battery pack from the battery replacement vehicle or install the battery pack on the battery replacement vehicle, the battery replacement device is adjusted to a height position corresponding to the chassis of the battery replacement vehicle by lifting and moving the battery replacement main body, and then the battery replacement device is extended. When it is necessary to place the depleted battery in the battery compartment for charging or take the fully charged battery out of the battery compartment, the battery replacement device is adjusted to a height position corresponding to the battery compartment by lifting and moving the battery replacement main body, and then the battery replacement device is extended to take and place the battery pack, thereby realizing the battery disassembly and installation operation on the battery replacement vehicle and / or the battery transfer operation between the battery rack and the battery compartment. In the present application, the battery replacement device is arranged in the battery replacement main body, so that the battery replacement device is extended from the battery replacement main body to take and place the battery pack. When the battery replacement device is actually used to take and place the battery pack, it only needs to extend from the battery replacement main body and enter the space below the battery replacement vehicle or the battery compartment, avoiding the occupation of the space below the vehicle and the space in the battery compartment caused by the whole battery replacement equipment entering the bottom of the vehicle and the battery compartment. Even if the battery replacement vehicle is on the battery replacement platform flush with the ground, the space below the vehicle body can also provide more operation space for the disassembly or installation of the battery pack, so that the battery replacement operation is more convenient and fast, and the service life is reduced and safety hazards are avoided due to the excavation of the ground below the battery replacement platform to create a subsidence space.The battery rack and the support frame share columns or are set independently of each other. When the two share columns, the battery transfer distance between the battery rack and the battery swapping equipment can be shortened, thereby further improving the battery swapping efficiency. At the same time, it can also simplify the equipment structure, save installation space and equipment costs. In addition, the columns of the battery rack guide the lifting and lowering of the battery swapping body, so that the stability of the lifting and lowering of the battery swapping body is greatly improved, and the optimal design of the structure of the battery swapping equipment and the battery rack is obtained, which reduces the structural complexity, makes the overall structure more compact, has higher strength, and saves space resources.

[0012] Preferably, the battery compartment is provided with a first battery locking mechanism for locking the battery pack, and the battery swapping vehicle is provided with a second battery locking mechanism for locking the battery pack. 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 for locking the battery pack in the battery compartment is consistent with the second battery locking mechanism for locking the battery pack on the battery swapping vehicle, so that the battery swapping device's pick-up, placement, transportation, locking and unlocking actions for the battery pack in the battery compartment are completely consistent with the pick-up, placement, transportation, locking and unlocking actions performed under the battery swapping vehicle, which greatly reduces the design burden on the control program and the structural design burden when the battery transfer equipment realizes the interaction of battery packs 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 support structures and locking and unlocking structures can be used. 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, which reduces the design cost of the locking mechanism, improves the smoothness and accuracy of battery swapping, shortens the battery swapping time, and enhances the user's battery swapping experience.

[0014] Preferably, support beams for supporting the battery pack are provided on both sides of the battery compartment along the entry and exit direction of the battery pack, and the support beams are located in the top area of ​​the battery compartment. The first battery locking mechanisms are provided on the support beams one by one, and the first battery locking mechanisms include a plurality of lock bases with lock slots, lock tongues movably provided in the lock slots, 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 using two longitudinal beams to carry the battery pack, this solution uses the first battery locking mechanism to suspend the battery pack on the supporting beams on both sides of the top of the battery compartment, so that the connection between the battery pack and the battery rack is realized at the top of the battery compartment and the battery pack. On the one hand, there is no need to set longitudinal beams to support the battery pack at the bottom of the battery compartment, so that after the battery pack enters the battery compartment, there is a part of the space below to avoid the battery tray of the battery replacement device, avoiding the interference of the battery rack on the battery tray entering the battery compartment. On the other hand, the battery pack is mostly suspended on battery replacement vehicles (especially heavy trucks, light trucks, etc.). The locking is achieved in this way, therefore, the battery pack is also locked in the battery rack by hanging, so that the battery rack and the battery-swapping vehicle form a greater correlation and better matching, to ensure that the same set of battery-swapping equipment performs exactly the same actions with the battery interactions between the battery-swapping vehicle and the battery rack. Taking the locking of the battery pack as an example, the first battery locking mechanism that locks the battery pack to the battery compartment of the battery-swapping equipment and the second battery locking mechanism that locks the battery pack to the battery-swapping vehicle are both pre-installed by the rising of the battery-swapping body to allow the lock shaft to enter the vertical opening of the lock slot, and then move forward to enter the horizontal opening of the lock slot, so that the lock shaft is limited and locked in the lock slot by the lock tongue.

[0016] Preferably, the battery rack includes two rows of column groups arranged at intervals, the two rows of column groups are connected by multiple longitudinal beams, the battery compartment is formed between the two rows of column groups, each row of column groups includes two columns spaced apart along the driving direction of the battery swap vehicle on the battery swap platform, and the two ends of the support 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 the rectangle, and the enclosed battery compartment is generally a rectangular space with a regular structure, which is relatively compatible with the most commonly used rectangular battery packs on the market. The two rows of column groups are connected by multiple longitudinal beams, so that the two column groups are connected as one, which helps to improve the stability of the structure. Moreover, the two ends of the supporting beam are connected to the two columns of each row of column groups, so that the supporting beam not only serves as a connecting structure for the two columns of the same column group, but also serves as a supporting structure for suspending the battery pack, achieving multiple uses. On the basis of improving the structural strength and stability of the battery rack, the battery rack structure 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 energy storage capacity and improving the cruising range of the battery swap vehicle.

[0018] Preferably, the supporting beam includes a square tube and a first U-shaped plate, the square tube is connected to two columns, the bottom wall of the first U-shaped plate is connected to the side wall of the square tube facing the battery compartment so that the opening of the first U-shaped plate faces the battery compartment, the multiple lock bases are arranged on the side wall of the first U-shaped plate located below, 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 bolster consists of a square tube and a first U-shaped plate. The square tube directly connects the two columns, and the first U-shaped plate is attached to the square tube. The combination of the square tube and the first U-shaped plate not only improves the stability of the connection between the two columns and reduces the risk of battery rack shaking, but also ensures that the bolster itself has relatively high strength, significantly improving its pressure-bearing capacity and reducing the risk of deformation when the battery pack is suspended. In addition, the internal space of the first U-shaped plate forms a space for the lock link to move the lock tongue. This facilitates the upward movement of the lock link during battery pack locking and unlocking, driving the lock tongue to avoid the lock shaft and allowing the lock shaft to enter and exit the lock slot.

[0020] Preferably, the supporting beam includes a second U-shaped plate, the opening of the second U-shaped plate faces upward and the two ends of the side walls are respectively connected to the adjacent columns, the side walls of the columns facing the battery compartment are connected to the bottom wall and the side walls at both ends of the second U-shaped plate through multiple reinforcing ribs, the multiple 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 support beam is composed of a second U-shaped plate and multiple reinforcing ribs. The space above the bottom wall of the second U-shaped plate forms a movement space for the lock link to drive the lock tongue. This facilitates the upward movement of the lock link to drive the lock tongue to avoid the lock shaft during the locking and unlocking process of the battery pack, allowing the lock shaft to enter and exit the lock slot. One side wall of the second U-shaped plate forms a large-area connection with the two columns, improving the stability of the connection between the two columns and reducing the risk of battery rack shaking. Moreover, the reinforcing rib plate connects the columns to the two side walls and bottom wall of the second U-shaped plate, ensuring that the support beam has relatively high structural strength and connection strength, thereby significantly improving the pressure-bearing capacity and reducing the risk of deformation when the battery pack is suspended.

[0022] Preferably, the battery rack includes two mounting beams provided on the back side opposite to the opening, the two mounting beams are arranged vertically and fixedly connected to the column group through the longitudinal beams; the battery swap station also includes an electrical connection device provided in the battery compartment, the electrical connection device is provided 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, the two mounting beams connect the multiple longitudinal beams on the back of the battery rack together, which plays a structural reinforcement role and further improves the structural stability of the battery rack; on the other hand, the two mounting beams enclose an installation space for the electrical connection device and realize the installation and support of the electrical connection device, thereby optimizing the installation layout of the electrical connection device on the battery rack, so that when the battery pack is moved to lock 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. In other words, the locking action of the battery pack in the battery compartment is completed synchronously with the action of the electrical connection device to achieve electrical connection. Of course, the unlocking action of the battery pack in the battery compartment is also completed synchronously with the action of disengaging the electrical connection device, making the battery replacement device a direct actuator for operating the connection between the battery pack and the electrical connection device, eliminating the existing steps of sending the battery pack into the battery compartment and then manually plugging it in to achieve charging, making the interaction of the battery pack in the battery compartment more automated, saving manpower and improving efficiency.

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

[0025] In this technical solution, two counterweights are arranged on both sides of the electrical connection device and are located on the back side of the battery rack as a whole. On the one hand, the counterweights can counterweight the battery rack, increase the overall weight of the battery storage device, and thereby improve the standing stability of the battery rack on the ground. On the other hand, the counterweights can be slidably arranged. Therefore, in a preferred embodiment, the counterweights can also counterweight the battery exchange body as a balancing structure for the lifting and lowering of the battery exchange body. When the battery exchange body rises, the counterweights descend, and when the battery exchange body descends, the counterweights rise, thereby improving the lifting and lowering stability of the battery exchange body.

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

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

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

[0029] In this technical solution, a mobile component is provided to drive the battery exchange body to move up and down along the support frame, thereby adjusting the height of the battery exchange device. At the same time, the battery exchange body and the mobile component are rotatably connected, which facilitates the adjustment of the angle of the battery exchange body, thereby adjusting the extension angle of the battery exchange device. When the battery to be transported is located at a deflection angle, it can be accurately positioned and extended through rotation adjustment to effectively transport the battery. Moreover, the rotatable battery exchange body makes the arrangement of the battery storage device more flexible and more scalable. When the battery rack is arranged around the circumference of the battery exchange device, the rotation of the battery exchange body enables the battery exchange device to interact with the battery rack at any position for battery packs, thereby improving the battery transportation efficiency.

[0030] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows: the battery swap platform provides a parking and battery swap space for the battery swap vehicle, so that the battery swap vehicle can be parked at the corresponding battery swap position on the battery swap platform; the battery storage device is used to temporarily store the battery pack, and a charging device can also be installed on the battery rack to meet the charging needs of the depleted battery during temporary storage; the battery swap equipment serves as a transfer structure, which is used to perform the interactive work of the battery pack between the battery compartment and the battery swap vehicle, including removing the depleted battery on the battery swap vehicle and placing it in the battery compartment for temporary storage, and removing the fully charged battery in the battery compartment and installing it on the battery swap vehicle. The battery swap equipment can be set on one or both sides of the battery swap platform along the driving direction of the battery swap vehicle on the battery swap platform, so that single-sided and / or double-sided battery swapping can be achieved. For example, during double-sided battery swapping, the battery swap equipment on one side is used to remove the depleted battery, and the battery swap equipment on the other side is used to install the fully charged battery. The battery swap equipment on both sides can synchronously perform battery swapping actions without interfering with each other, thereby improving the battery swapping efficiency. The opening of the battery rack faces the battery swap equipment, and the battery swap equipment can directly take and place the battery pack in the battery compartment through the opening. The battery rack is vertically arranged with multiple battery compartments, which make full use of the height space and can accommodate multiple battery packs at the same time, greatly reducing the footprint of the battery rack. The battery swap body can be raised and lowered on the support frame to adjust the height of the battery swap device. When the battery pack needs to be removed from the battery swap vehicle or installed on the battery swap vehicle, the battery swap device is adjusted to a height position corresponding to the chassis of the battery swap vehicle by raising and lowering the battery swap body, and then the battery swap device is extended. When a low-charged battery needs to be placed in the battery compartment for charging or a fully charged battery needs to be taken out of the battery compartment, the battery swap device is adjusted to a height corresponding to the battery compartment by raising and lowering the battery swap body, and then the battery swap device is extended to take and place the battery pack, thereby realizing battery disassembly and assembly operations on the battery swap vehicle and / or battery transfer operations between the battery compartments of the battery rack. The present application arranges the battery swap device inside the battery swap body so that the battery swap device can be extended from the battery swap body to perform the operation of taking and placing the battery pack. When taking and placing the battery pack, the battery swap device only needs to be extended from the battery swap body and then enter the bottom of the battery swap vehicle or enter the battery compartment, avoiding the battery swap equipment as a whole entering the bottom of the battery swap vehicle and the battery compartment, thereby occupying the bottom space of the vehicle and the space inside the battery compartment. Even if the battery swap vehicle is changing batteries on a battery swap platform flush with the ground, the bottom of the vehicle body can provide more operating space for the removal or installation of the battery pack, making the battery swap operation simpler and faster, and effectively avoiding the reduction in life and safety hazards caused by digging a pit under the battery swap platform to create a sunken space on the ground.The battery rack and the support frame share columns or are set independently of each other. When the two share columns, the battery transfer distance between the battery rack and the battery swapping equipment can be shortened, thereby further improving the battery swapping efficiency. At the same time, it can also simplify the equipment structure, save installation space and equipment costs. In addition, the columns of the battery rack guide the lifting and lowering of the battery swapping body, so that the stability of the lifting and lowering of the battery swapping body is greatly improved, and the optimal design of the structure of the battery swapping equipment and the battery rack is obtained, which reduces the structural complexity, makes the overall structure more compact, has higher strength, and saves space resources.

[0053] like Figures 1 to 14 As shown, a battery swap station provided in the present application includes a battery swap device 1, a battery swap platform 2 and a battery storage device; the battery swap device 1 is arranged on at least one side of the battery swap platform 2 along the driving direction of the battery swap vehicle, and the battery storage device at least includes a battery storage device 3 arranged on at least one side of the battery swap device 1 in a direction parallel to the driving direction of the battery swap vehicle, and the battery storage device 3 includes a battery rack 31 arranged with an opening toward the battery swap device 1, and the battery rack 31 is vertically arranged in sequence with multiple battery compartments 32; the battery swap device 1 includes: a fixed support frame 11, a battery swap body 12 arranged between the support frames 11 and movable by lifting and lowering, and a battery swap device 13 arranged in the battery swap body 12 and telescopically movable to the outside of the support frame 11, the battery rack 31 and the support frame 11 share a column 311 or are arranged independently of each other, and the battery disassembly and assembly operations of the battery swap vehicle and / or the battery transfer operations between the battery compartment 32 of the battery rack 31 are realized through the telescopic movement of the battery swap device 13 and the lifting and lowering movement of the battery swap body 12.

[0054] In this technical solution, the battery swap platform 2 provides a parking and battery swap space for the battery swap vehicle. The battery swap vehicle can drive in from one end of the battery swap platform and then park at the corresponding battery swap position. At the battery swap position, the battery swap equipment 1 can perform the battery pack replacement operation; the battery storage device is used to temporarily store the battery pack, and a charging device can also be installed on the battery rack 31 to meet the charging needs of the depleted battery during temporary storage. After the battery is fully charged, the battery swap equipment 1 can be reinstalled on the battery swap vehicle; the battery swap equipment 1 serves as a battery pack transfer structure, which is used to perform the interactive work of the battery pack between the battery compartment 32 and the battery swap vehicle, including removing the depleted battery on the battery swap vehicle and placing it in the battery compartment 32 for temporary storage, and removing the fully charged battery in the battery compartment 32 and installing it on the battery swap vehicle.

[0055] The battery swapping device 1 can be set 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 that single-sided and / or double-sided battery swapping can be achieved. Figure 1 The embodiment in which the battery swapping device 1 is arranged on one side of the battery swapping platform 2 is shown in FIG, realizing single-side battery swapping. Figure 2 The figure shows an embodiment in which the battery swapping equipment 1 is arranged on both sides of the battery swapping platform 2. The battery swapping equipment 1 on one side is used to remove the depleted battery, and the battery swapping equipment 1 on the other side is used to install the fully charged battery. The battery swapping equipment 1 on both sides can synchronously perform the battery swapping actions without interfering with each other, thereby improving the battery swapping efficiency.

[0056] The opening of the battery rack 31 faces the battery swap device 1, and the battery swap device 1 can directly take out and put the battery pack in the battery compartment 32 through the opening. The battery rack 31 is vertically arranged with multiple battery compartments 32 in sequence, which fully utilizes the height space and can accommodate multiple battery packs at the same time, greatly reducing the footprint of the battery rack 31 when accommodating multiple battery packs. The battery exchange body 12 can be raised and lowered on the support frame 11 to adjust the height of the battery exchange device 13. When the battery pack needs to be removed from the battery exchange vehicle or installed on the battery exchange vehicle, the battery exchange device 13 is adjusted to a height position corresponding to the chassis of the battery exchange vehicle by raising and lowering the battery exchange body 12, and then the battery exchange device 13 is extended. When a low-charged battery needs to be placed in the battery compartment 32 for charging or a fully charged battery needs to be taken out of the battery compartment 32, the battery exchange device 13 is adjusted to a height corresponding to the battery compartment 32 by raising and lowering the battery exchange body 12, and then the battery exchange device 13 is extended to take and place the battery pack, thereby realizing battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between the battery compartment 32 of the battery rack 31.

[0057] The present application arranges the battery exchange device 13 in the battery exchange body 12 so that the battery exchange device 13 extends from the battery exchange body 12 to perform the operation of taking and placing the battery pack. When actually taking and placing the battery pack, the battery exchange device 13 only needs to extend from the battery exchange body 12 and enter the bottom of the battery exchange vehicle or enter the battery compartment 32, thereby avoiding the battery exchange device 1 as a whole entering the bottom of the battery exchange vehicle and the battery compartment 32, thereby occupying the bottom space of the vehicle and the space inside the battery compartment 32. Even if the battery exchange vehicle exchanges batteries on a battery exchange platform 2 flush with the ground, the bottom of the vehicle body can provide more operating space for the removal or installation of the battery pack, making the battery exchange operation simpler and faster, and avoiding the reduction in life and safety hazards caused by digging a pit under the battery exchange platform 2 to create a sunken space on the ground. The battery rack 31 and the support frame 11 share the column 311 or are set independently of each other. Figures 1 to 4 The figure shows an embodiment in which the battery rack 31 and the support frame 11 share a column 311. This design can shorten the battery transportation distance between the battery rack 31 and the battery exchange device 1, thereby further improving the battery exchange efficiency. At the same time, it can also simplify the equipment structure, save installation space and equipment costs. In addition, the column 311 of the battery rack 31 guides the lifting and lowering of the battery exchange body 12, so that the stability of the lifting and lowering of the battery exchange body 12 is greatly improved, and the optimal design of the structure of the battery exchange device 1 and the battery rack 31 is obtained, which reduces the structural complexity, makes the overall structure more compact and has higher strength, and saves space resources. Specifically, as shown in FIG. Figure 3 and Figure 4 As shown, in an embodiment in which a battery storage device 3 is provided on each side of the battery exchange equipment 1, four adjacent columns 311 of the battery racks 31 on both sides constitute a fixed support frame 11, and the battery exchange body 12 is raised and lowered along these four columns 311. Figure 13 The embodiment shown is that the battery rack 31 and the support frame 11 are independently arranged. In this case, there is a distance between the battery rack 31 and the support frame 11 .

[0058] Regarding the way in which the battery exchange device 13 realizes telescopic movement, in a preferred embodiment, as Figures 3 to 5 As shown, the battery exchange device 13 can also include a telescopic mechanism 131. The telescopic mechanism 131 can be a fork, which can be extended and retracted relative to the battery exchange body 12 through the telescopic mechanism 131. The telescopic mechanism 131 can be provided with a battery tray 132 for carrying the battery pack and an unlocking pin 133 for locking and unlocking the battery pack. When the telescopic mechanism 131 is extended toward the battery exchange vehicle on the battery exchange platform 2, the battery tray 132 is sent to the bottom of the battery exchange vehicle for locking, unlocking, disassembling and transporting the battery pack. When the telescopic mechanism 131 is extended toward the battery rack 31, the battery tray 132 is sent into the battery compartment 32 for locking, unlocking, disassembling and transporting 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 a second battery locking mechanism for locking the battery pack is provided in the battery swapping vehicle. The first battery locking mechanism 33 and the second battery locking mechanism are consistent, so that the battery pack can perform the same locking or unlocking operation and battery transfer operation in the battery compartment 32 or on the battery swapping vehicle. Figure 3 、 Figure 4 、 Figure 5 and Figure 7 The figure shows an embodiment in which a first battery locking mechanism 33 is provided in the battery compartment 32. The accompanying drawings do not show the battery swapping vehicle and the second battery locking mechanism, but it is only necessary to make the first battery locking mechanism 33 and the second battery locking mechanism consistent. It can be understood by those skilled in the art that by making the first battery locking mechanism 33 consistent with the second battery locking mechanism, the battery swapping device 13 makes the battery pack's pick-up, placement, transportation, locking and unlocking actions in the battery compartment 32 completely consistent with the pick-up, placement, transportation, locking and unlocking actions under the battery swapping vehicle, which greatly reduces the design burden on the control program and the structural design when the battery transfer equipment 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 and unlocking structures can be used, 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 due to their consistency, which reduces the design cost of the locking mechanism, improves the smoothness and accuracy of battery swapping, shortens the battery swapping time, and enhances the user's battery swapping experience.

[0060] More preferably, Figures 6 to 11As shown, a bolster 312 for supporting the battery pack is provided on each side of the battery compartment 32 along the direction in which the battery pack enters and exits. The bolster 312 is located at the top area of ​​the battery compartment 32. A first battery locking mechanism 33 is provided on each bolster 312 in a one-to-one correspondence. The first battery locking mechanism 33 includes multiple lock bases 331 with lock slots 3311, lock tongues 332 movably disposed within the lock slots 3311, and a lock link 333 connecting the multiple lock tongues 332. The first battery locking mechanism 33 cooperates with multiple lock shafts on both sides of the battery pack to suspend and secure the battery pack from both sides. Specifically, the lock bases 331 on each bolster 312 can be spaced apart along the direction in which the battery pack enters and exits. The battery pack is suspended and locked by multiple lock bases 331 on the same side, thereby avoiding stress concentration and improving the stability of the battery pack's suspension and locking within the battery compartment 32. The first battery locking mechanism 33 includes a plurality of lock bases 331, each lock base 331 is provided with a corresponding lock tongue 332, all the lock tongues 332 on the same support beam 312 are connected by a lock link 333, and the lock tongue 332 is used to open or close the lock slot 3311. When the battery pack is locked, since the lock shaft on the battery pack needs to enter the lock slot 3311, the lock link 333 can be pushed up to drive all the lock tongues 332 to move upward to open the lock slot 3311, so that the lock shaft can enter the lock slot 3311, and then the push on the lock link 333 is canceled, and the lock link 333 is locked. When the battery pack is unlocked, the lock shaft on the battery pack needs to be separated from the lock slot 3311. Therefore, the lock link 333 can be pushed up to drive all the lock tongues 332 to move upward to open the lock slot 3311, so that the lock shaft can be separated from the lock slot 3311. After the lock shaft is separated from the lock slot 3311, the push on the lock link 333 is cancelled, and the lock link 333 drives the lock tongue 332 to move downward to reclose the lock slot 3311.Those skilled in the art will appreciate that, compared to the traditional battery rack 31 which uses two longitudinal beams to carry the battery pack, this solution uses a first battery locking mechanism 33 on the supporting 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 achieved at the battery compartment 32 and the top of the battery pack. On the one hand, there is no need to set longitudinal beams supporting the battery pack at the bottom of the battery compartment 32, so that after the battery pack enters the battery compartment 32, there is a portion of space left below to avoid the battery tray 132 of the battery swap device 13, thereby avoiding the battery rack 31 from interfering with the battery tray 132 entering the battery compartment 32. On the other hand, for battery packs in battery swap vehicles (especially heavy trucks, In the present application, the battery pack is also locked by suspension in the battery rack 31, so that the battery rack 31 has a greater correlation and better matching with the battery swapping vehicle, so as to ensure that the same set of battery swapping equipment 1 performs exactly the same actions in 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 locked to the battery swapping vehicle. Both of them are pre-locked by the rising of the battery swapping body 12 to allow the lock shaft to enter the vertical opening of the lock slot, and then move forward to enter the lock slot, and then the lock shaft is limited to be locked in the lock slot by the lock tongue.

[0061] Regarding the specific structure of the battery rack 31, in a preferred embodiment, as shown in FIG. Figure 8 and Figure 9As shown, the battery rack 31 includes two rows of column groups arranged at intervals, and 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 apart along the direction of travel of the battery swap vehicle on the battery swap platform 2, and the two ends of the supporting 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 the rectangle, and the enclosed battery compartment 32 is generally a rectangular space with a regular structure, which has relatively good adaptability with 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 as one, which helps to improve the structural stability. Moreover, the two ends of the support beam 312 are connected to the two columns 311 of each row of column groups, so that the support 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 suspending the battery pack, achieving multiple uses. 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, and 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, thereby increasing the amount of electrical energy stored and improving the range of the battery-swap vehicle. Preferably, the column 311 and the longitudinal beam 313 can be connected by welding and / or bolts, and the support beam 312 and the column 311 can also be connected by welding and / or bolts to improve the connection strength.

[0062] The present application does not limit the specific structure of the bolster 312, which includes at least the following two embodiments:

[0063] Example 1: Figure 10As shown, the supporting beam 312 includes a square tube 3121 and a first U-shaped plate 3122. The square tube 3121 is connected to the 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 side wall of the first U-shaped plate 3122 located below. 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 bolster 312 consists of two parts: a square tube 3121 and a first U-shaped plate 3122. The square tube 3121 directly connects the two columns 311, and the first U-shaped plate 3122 is attached to the square tube 3121. The combination of the square tube 3121 and the first U-shaped plate 3122 not only enhances the stability of the connection between the two columns 311 and reduces the risk of shaking of the battery rack 31, but also ensures that the bolster 312 itself has relatively high strength, significantly improving its pressure-bearing capacity and reducing the risk of deformation when the battery pack is suspended. Furthermore, the interior space of the first U-shaped plate 3122 creates space for the lock link 333 to move the lock tongue 332. This facilitates the upward movement of the lock link 333 during battery pack locking and unlocking, driving the lock tongue 332 out of the way of the lock shaft and allowing the lock shaft to enter and exit the lock slot 3311. The bottom wall of the square tube 3121 and the first U-shaped plate 3122 is preferably welded, providing a strong connection that is not easily deformed or loosened.

[0064] Example 2: Figure 11As shown, the bolster 312 includes a second U-shaped plate 3123. The opening of the second U-shaped plate 3123 faces upward, and the ends of the side walls are respectively connected to the adjacent columns 311. The side walls of the columns 311 facing the battery compartment 32 are connected to the bottom wall and the side walls of the second U-shaped plate 3123 via multiple reinforcing ribs 3124. Multiple lock bases 331 are provided 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 space for the lock link 333 to drive the lock tongue 332 to move. In this technical solution, the bolster 312 is composed of the second U-shaped plate 3123 and multiple reinforcing ribs. The space above the bottom wall of the second U-shaped plate 3123 forms a space for the lock link 333 to drive the lock tongue 332 to move. This 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, allowing the lock shaft to enter and exit the lock slot 3311. One sidewall of the second U-shaped plate 3123 forms a large-area connection with the two columns 311, enhancing the stability of the connection between the two columns 311 and reducing the risk of shaking of the battery rack 31. Furthermore, the reinforcing ribs 3124 connect the columns 311 with the two sidewalls and bottom wall of the second U-shaped plate 3123, ensuring that the support beam 312 has relatively high structural strength and connection strength, significantly improving its pressure-bearing capacity and reducing the risk of deformation when the battery pack is suspended. The sidewalls of the second U-shaped plate 3123 and the columns 311 are preferably connected by welding. The columns 311, reinforcing ribs 3124, and second U-shaped plate 3123 are also preferably connected by welding, which provides high connection strength and is not easily deformed or loosened.

[0065] Regarding the structure of the battery storage device 3, in a preferred embodiment, as shown in FIG. Figures 6 to 9As shown, the battery rack 31 includes two mounting beams 314 provided on the back side opposite to the opening, and the two mounting beams 314 are arranged vertically and fixedly connected to the column group through the longitudinal beams 313; the battery swap station also includes an electrical connection device 34 provided in the battery compartment 32, and the electrical connection device 34 is provided between the two mounting beams 314 and its interface end 341 is facing the opening of the battery compartment 32; when the battery pack moves to lock 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 the multiple longitudinal beams 313 on the back of the battery rack 31 together, playing a structural reinforcement role, further improving the structural stability of the battery rack 31; on the other hand, the two mounting beams 314 enclose the installation space of the electrical connection device 34 and realize 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, so that when the battery pack moves to the first battery locking mechanism 33 to achieve locking, the electrical connection port of the battery pack and the interface end of the electrical connection device 34 are connected. 341 just realizes electrical connection. In other words, the locking action of the battery pack in the battery compartment 32 is completed synchronously with the action of the electrical connection device 34 realizing electrical connection. Of course, the unlocking action of the battery pack in the battery compartment 32 is also completed synchronously with the action of disengaging the electrical connection device 34, making the battery replacement device 13 a direct actuator for operating the connection between the battery pack and the electrical connection device 34, eliminating the existing steps of putting the battery pack into the battery compartment and then manually plugging it in to realize charging, making the interaction of the battery pack in the battery compartment 32 more automated, saving manpower and improving efficiency.

[0066] More preferably, Figure 7 and Figure 9 As shown, the battery swap station also includes a counterweight unit provided on the other side of the battery rack 31 relative to the battery swap device 1, and the counterweight unit includes two counterweights 35 slidably connected to the two sides of the electrical connection device 34. In this technical solution, the two counterweights 35 are arranged on both sides of the electrical connection device 34, and are located on the back side of the battery rack 31 as a whole. On the one hand, the counterweights 35 can counterweight the battery rack 31, increase the overall weight of the battery storage device, and thereby improve the standing stability of the battery rack 31 on the ground. On the other hand, the counterweights 35 can be slidably arranged. Therefore, in a preferred embodiment, the counterweights 35 can also counterweight the battery swap body 12, serving as a balancing structure for the lifting and lowering of the battery swap body 12. When the battery swap body 12 rises, the counterweights 35 fall, and when the battery swap body 12 falls, the counterweights 35 rise, thereby improving the lifting and lowering stability of the battery swap body 12. Specifically, a guide rail 315 for the counterweight 35 to slide up and down can be set on the back side of the battery rack 31. A guide rail 315 is provided on both sides of each counterweight 35, and the counterweight 35 is slidably connected to the guide rails 315 on both sides.

[0067] As a preferred embodiment of the present application, Figures 1 to 4 As shown, along the direction parallel to the driving 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 located 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 figure shows that the above-mentioned battery swap station adopts the above two preferred embodiments at the same time, that is, battery storage devices 3 are provided on the front and rear sides of the battery swap device 1 and the other side opposite to the battery swap platform 2, which can further utilize the installation space around the battery swap device 1, and increase the battery storage space and the number of available batteries in the battery swap station, effectively utilize the space in the battery swap station, and increase the battery swap scale of the battery swap station. Moreover, during operation, fully charged batteries can be transferred to the battery rack 31 closer to the battery swap device 1 for convenient and quick access, and low-charged batteries can be transferred to the battery rack 31 farther away from the battery swap device 1 for charging and standby. This makes the management and allocation of fully charged batteries and low-charged batteries in the entire battery swap station more reasonable, which is conducive to further improving the battery swap efficiency. In this embodiment, the extension direction of the telescopic mechanism 131 toward the battery swap platform 2 and the extension direction toward each battery rack 31 are basically perpendicular to each other. Of course, in other embodiments, each battery rack 31 and the battery swap platform 2 can also be arranged in a pentagonal, hexagonal or other different arrangements around the battery swap device 1.

[0068] More preferably, Figure 3 、 Figure 4 and Figure 14As shown, the battery exchange body 12 is connected to the support frame 11 through the mobile component 4, and the battery exchange body 12 is rotatably connected to the mobile component 4. By rotating the battery exchange body 12, the orientation of the battery exchange device 13 can be adjusted to facilitate telescopic movement to perform battery disassembly and assembly operations and / or battery transfer operations. Specifically, the mobile component 4 can use a frame structure with rollers 41, and the battery exchange body 12 is rotatably connected to the bottom of the frame structure. The frame structure is lifted and lowered by rolling along the support frame 11 by the rollers 41. In the embodiment in which the battery rack 31 and the support frame 11 share a common column 311, the frame structure is lifted and lowered by rolling along the column 311 of the battery rack 31 by the rollers 41. In a preferred embodiment, the battery exchange body 12 can be rotatably connected to the mobile component 4 by a drive motor and a gear mechanism. The gear mechanism includes a driving gear and a driven gear. The drive motor is fixed to the mobile component 4. The driving gear is connected to the output shaft of the drive motor. The driving gear and the driven gear are meshed, and the driven gear is fixed to the battery exchange body 12. In this technical solution, the mobile component 4 is provided to drive the battery exchange body 12 to move up and down along the support frame 11, thereby adjusting the height of the battery exchange device 13. At the same time, the battery exchange body 12 and the mobile component 4 are rotatably connected, which facilitates the adjustment of the angle of the battery exchange body 12, thereby adjusting the extension angle of the battery exchange device 13. When the battery to be transported is located at a deflection angle, it can be accurately positioned and extended through rotation adjustment to effectively transport the battery. Moreover, the rotatable battery exchange body 12 makes the arrangement of the battery storage device 3 more flexible and more scalable. When the battery rack 31 is arranged around the circumference of the battery exchange equipment 1, the rotation of the battery exchange body 12 enables the battery exchange device 13 to interact with the battery rack 31 at any position for battery packs, thereby improving the battery transportation efficiency.
