[0027] An embodiment of the present application provides a battery swapping station system, and the battery swapping station system includes: a battery swapping compartment and a battery compartment.

[0028] See Figure 1 , Figure 1 Schematic structural diagram of a battery swapping station system provided by an embodiment of the present application, mainly including two compartments: a battery swapping compartment and a charging compartment.

[0029] In the battery swapping compartment, it includes a front-wheel adjustment structure, a rear-wheel adjustment structure, and a battery swapping component; among them, a horizontal adjustment roller wheel fixing groove is provided in the front-wheel adjustment structure, the rear-wheel adjustment structure includes a servo motor, a support component, and a rear-wheel fixing component, and the servo motor is communicatively connected to the support component; the battery swapping component adopts a sunken layout and includes an unlocking and locking platform and a rail-guided vehicle. The unlocking and locking platform is installed on the top of the battery swapping component, and the unlocking and locking platform is flush with the ground of the battery swapping compartment. The rail-guided vehicle transports batteries between the battery swapping compartment and the battery compartment through a preset track between the battery swapping compartment and the battery compartment.

[0030] In the battery compartment, it includes a battery rack, and the battery rack is used to store batteries.

[0031] Specifically, Figure 1 The shown battery swapping station system mainly includes two types of compartments, namely, a battery swapping compartment for swapping batteries for vehicles, and a battery storage compartment for storing batteries. On the floor of the battery swapping compartment, there are installed a front-wheel adjustment structure for fixing the front wheels of the battery swapping vehicle, and a rear-wheel adjustment structure for fixing the rear wheels of the battery swapping vehicle. When the battery swapping vehicle is swapping batteries in the battery swapping compartment, its front wheels are parked at the front-wheel adjustment structure, and its rear wheels are parked at the said rear-wheel adjustment structure.

[0032] When the front wheels of the battery swapping vehicle drive into the front-wheel adjustment structure, first, the horizontal adjustment rollers are used to adjust the angle of the battery swapping vehicle in the X direction to center the battery swapping vehicle, that is, to make the body central axis of the battery swapping vehicle correspond to the central axis shown by the front-wheel adjustment structure in the battery swapping compartment, and then the front wheels of the battery swapping vehicle are fixed by the wheel fixing grooves in the front-wheel adjustment structure. As Figure 1 shown, in the battery swapping compartment, the X direction is the direction from the rear-wheel adjustment structure to the front-wheel adjustment structure.

[0033] Specifically, the front-wheel adjustment structure designed in the embodiments of the present application can be compatible with vehicles having a wheelbase in the range of 2690 mm to 3200 mm for battery swapping.

[0034] On the other side, the battery swapping vehicle is adjusted in the vertical direction by the rear-wheel adjustment structure and the rear wheels of the battery swapping vehicle are fixed. In the embodiments of the present application, the vertical direction is the direction perpendicular to the ground of the battery swapping station. When the rear wheels of the battery swapping vehicle drive into the rear-wheel adjustment structure, the rear wheels are parked on the supporting components of the rear-wheel adjustment structure, and the height of the supporting components is controlled by a servo motor to adjust the height and angle of the battery swapping vehicle parked in the vertical direction, so that the front and rear heights of the battery of the battery swapping vehicle are kept consistent. After the height adjustment of the supporting components is completed, the rear wheels of the battery swapping vehicle are fixed by the rear-wheel fixing components of the rear-wheel adjustment structure.

[0035] In the battery storage compartment, there are installed a battery rack for storing batteries and a palletizer for handling batteries. In the battery rack, not only fully charged batteries provided for each battery swapping vehicle to replace are stored, but also undercharged batteries removed from the battery swapping vehicles are stored. In the battery storage compartment, a palletizer can further be installed to pick up and place each battery on the battery rack.

[0036] In the battery swapping station, there is also installed a battery swapping component, which is mainly composed of an unlocking and locking platform and a Rail Guided Vehicle (RGV). Among them, the unlocking and locking platform is used to disassemble and assemble batteries for the battery swapping vehicle, and the RGV transports batteries between the battery swapping compartment and the battery storage compartment through the preset tracks in the battery swapping station. The battery swapping component adopts a sunken layout in the battery swapping station, and the unlocking and locking platform of the battery swapping component is flush with the ground of the battery swapping station.

[0037] In an embodiment of the present application, after the battery swapping vehicle drives into the battery swapping chamber, the front wheel adjustment structure centers the battery swapping vehicle, and the rear wheel adjustment structure levels the battery swapping vehicle, and respectively fixes the front and rear wheels of the battery swapping vehicle after adjustment. Thus, the battery pack disassembly and assembly position of the battery swapping vehicle can be corresponded to the unlocking and locking platform of the battery swapping component, that is, the battery disassembly and assembly position of the battery swapping vehicle is aligned with the unlocking and locking platform of the battery swapping component. After the battery swapping vehicle is fixed, the battery of the battery swapping vehicle can be directly disassembled and assembled through the unlocking and locking platform of the battery swapping component, which can effectively reduce the battery swapping time. Moreover, since the battery swapping component adopts a sunken layout, the unlocking and locking platform is flush with the ground of the battery swapping station. Therefore, when the battery swapping vehicle drives into the battery swapping station, the battery swapping component will not block the driving of the battery swapping vehicle; when the battery swapping component disassembles and assembles the battery of the battery swapping vehicle, the front wheel adjustment structure and the rear wheel adjustment structure are used to finely adjust the battery swapping vehicle, so that the battery pack disassembly and assembly position of the battery swapping vehicle is horizontal, without the need to lift the battery swapping vehicle significantly, thereby reducing the lifting height of the battery swapping vehicle during the battery swapping process, reducing the time consumed during the battery swapping process, and improving the battery swapping efficiency.

[0038] In addition, through the sunken layout of the battery swapping component, the unlocking and locking platform of the battery swapping component is flush with the ground of the battery swapping station, saving the space of the battery swapping station in the vertical direction, and thus improving the compatibility of the battery swapping station with battery swapping vehicles of different heights.

[0039] In a possible implementation manner, the support component includes an adjusting rod and a support platform; the adjusting rod is communicatively connected to the servo motor.

[0040] See Figure 2 , Figure 2 which is a schematic structural diagram of the support component provided by the embodiment of the present application. In the embodiment of the present application, the support platform is used to carry the rear wheels of the battery swapping vehicle. The support platform is connected to the adjusting rod and is installed at the top of the adjusting rod; the adjusting rod is an adjustable structure. The servo motor drives the adjusting rod to move through its communication connection with the adjusting rod, so as to adjust the height of the support platform, thereby adjusting the height of the rear wheels of the battery swapping vehicle in the vertical direction and achieving the purpose of leveling the battery swapping vehicle.

[0041] In a possible implementation manner, the rear wheel adjustment structure further includes: a laser rangefinder; the laser rangefinder is communicatively connected to the servo motor.

[0042] A laser rangefinder is added to the rear-wheel adjustment structure to detect whether the front and rear heights of the battery pack of the battery-swapping vehicle are consistent, so as to determine whether the battery-swapping vehicle is leveled. When the battery-swapping vehicle is adjusted in the vertical direction through the rear-wheel adjustment structure, the servo motor controls the support component to rise or fall in response to the laser rangefinder detecting a gap in the front and rear heights of the battery pack of the battery-swapping vehicle, so as to adjust the rear-wheel height of the battery-swapping vehicle, making the front and rear heights of the battery pack of the battery-swapping vehicle consistent, so that the battery of the battery-swapping vehicle can be disassembled and assembled through the unlocking and locking platform of the battery-swapping component.

[0043] In a possible implementation, the system further includes: a buffer support arm; the buffer support arm is connected to the battery rack, and the buffer support arm is a folding structure.

[0044] The buffer support arm is installed in the battery compartment and connected to the battery rack. When there are multiple battery racks in the battery compartment, the buffer support arm can be installed on one of the battery racks, and the fully charged battery taken from the battery rack and the undercharged battery disassembled from the battery-swapping vehicle can be temporarily stored on the buffer support arm.

[0045] In the embodiment of the present application, the buffer support arm can be a folding structure. When it is necessary to place a battery on the buffer support arm, the folding structure of the buffer support arm is controlled to open, and when the buffer support arm is idle, the folding structure of the buffer support arm is controlled to close, so as to reduce the space occupied by the buffer support arm.

[0046] Further, the system further includes a lifting structure, the lifting structure is connected to the buffer support arm, and controls the buffer support arm to rise or fall along the battery rack.

[0047] Controlling the buffer support arm to rise or fall through the lifting structure is beneficial to improving the efficiency of taking and delivering batteries on the battery rack.

[0048] Specifically, in order to further improve the efficiency of taking and delivering batteries on the battery rack, a multi-layer support arm structure can be set for the buffer support arm, which are two layers of an upper buffer support arm and a lower buffer support arm. Multiple batteries can be transported in the battery rack simultaneously through the upper buffer support arm and the lower buffer support arm.

[0049] Similarly, the upper buffer support arm and the lower buffer support arm can also be folding structures. When it is necessary to place a battery on the upper buffer support arm or the lower buffer support arm, the corresponding upper buffer support arm or lower buffer support arm is controlled to open. It should be noted that in the embodiment of the present application, the actions of the upper buffer support arm, such as rising, falling, opening, etc., can be executed synchronously with the actions of the lower buffer support arm, or can be independent of the lower buffer support arm, that is, the actions of the upper buffer support arm and the lower buffer support arm can be executed synchronously or independently. The embodiment of the present application does not make specific limitations on this.

[0050] For example, when the battery swapping component removes the undercharged battery from the battery swapping vehicle and moves to the battery rack, it places the undercharged battery on the upper buffer support arm. The palletizer places the fully charged battery on the lower buffer support arm. Then, the lower buffer support arm transfers the fully charged battery to the battery swapping component, and the palletizer places the undercharged battery in the upper buffer support arm into the battery rack. After receiving the undercharged battery, instead of first placing the undercharged battery into the battery rack, the full charge battery and the undercharged battery are directly exchanged at the buffer support arm, saving the battery swapping time.

[0051] As an embodiment, the system further includes: a palletizer; the palletizer is installed in the battery compartment.

[0052] See Figure 3 , in the embodiment of the present application, the palletizer is installed in the battery compartment of the battery swapping station system and is used to pick up and place batteries from the battery rack and / or the buffer support arm. Through the palletizer, the fully charged battery can be taken out from the battery rack and placed on the buffer support arm; the undercharged battery can also be taken off from the buffer support arm and placed in the battery rack.

[0053] See Figure 4 , as an embodiment, when the RGV removes the undercharged battery from the battery swapping vehicle and transports the undercharged battery to the battery rack, the upper buffer support arm opens, and the lifting structure drives the undercharged battery to lift upward. When the upper buffer support arm reaches the preset position, the lower buffer support arm opens, and the palletizer places the fully charged battery on the lower buffer support arm. The lifting structure drives the upper buffer support arm and the lower buffer support arm to descend simultaneously until the fully charged battery is placed on the RGV. The RGV takes away the fully charged battery and transports it to the battery swapping compartment for battery installation.

[0054] In a possible implementation manner, the system further includes: a water chiller; the water chiller is installed on the top outside the battery compartment body.

[0055] As Figure 4 shown, a water chiller is installed on the top outside the battery compartment body, and the water chiller is used to dissipate heat from the batteries stored in the battery compartment. In addition, the outdoor unit of the air conditioner of the battery swapping station can also be installed on the top outside the battery compartment or the battery swapping compartment body.

[0056] Inside the battery compartment, each battery rack can be stacked vertically, making full use of the vertical space inside the battery compartment, improving the space utilization rate inside the battery compartment, and expanding the battery storage capacity inside the battery compartment.

[0057] Further, a fire water tank can also be provided under the battery rack. When abnormal conditions such as high temperature and smoking occur in the batteries in the battery rack, the abnormal batteries are transferred into the fire water tank by the palletizer to ensure the fire safety in the battery compartment. In the embodiment of the present application, in order to improve the rationality of the space layout in the battery compartment, if a buffer support arm is installed on a battery rack in the battery compartment, then a fire water tank is provided at the bottom of other battery racks without the buffer support arm.

[0058] In a possible implementation manner, the system further includes: a charging cabinet;

[0059] The charging cabinet is installed in the battery compartment and is connected to each battery on the battery rack to charge each battery on the battery rack.

[0060] See Figure 3 , the charging cabinet is installed in the battery compartment of the battery swapping station and is connected to each battery on the battery rack, and each battery on the battery rack is charged through the charging cabinet.

[0061] In addition, as Figure 3 shown, in the embodiment of the present application, a personnel duty room can also be provided in the battery compartment.

[0062] In a possible implementation manner, the system further includes: a rear-wheel centering fine-tuning component, and the rear-wheel centering fine-tuning component is composed of horizontal adjustment rollers.

[0063] In the embodiment of the present application, a rear-wheel centering fine-tuning component can also be added to the rear-wheel adjustment structure. The rear-wheel centering fine-tuning component is composed of horizontal adjustment rollers. In the embodiment of the present application, the front-wheel adjustment structure and the rear-wheel centering fine-tuning component are called to perform centering processing on the battery swapping vehicle simultaneously.

[0064] As an embodiment, the system includes one battery swapping compartment and multiple battery compartments.

[0065] In the embodiment of the present application, the number of battery compartments in the battery swapping station can be set according to actual needs.

[0066] See Figure 5 , Figure 5 is the structural schematic diagram of the medium-sized battery swapping station provided by the embodiment of the present application. Compared with Figure 1 , an additional battery compartment with the same capacity as Figure 1 is added, expanding the battery storage capacity in the battery swapping station.

[0067] See Figure 6 , Figure 6 is the structural schematic diagram of the double-channel large-scale battery swapping station provided by the embodiment of the present application. Compared with Figure 6 , Figure 6 on the other side of the battery swapping compartment, an additional one with the same capacity asFigure 5 Battery compartments with equal capacity further expand the battery storage capacity in the battery swapping station.

[0068] The system further includes: a rear-wheel centering fine-tuning component, which consists of a horizontal adjustment roller.

[0069] Furthermore, to ensure fire safety in the battery swapping station, corresponding fire protection devices can also be deployed inside the station. For example, fire detectors are deployed in each compartment and each area inside the battery swapping station, and no-entry warning lights and audible and visual alarms are deployed outside the compartments of the battery swapping station; in response to a fire detector in a certain compartment or area inside the battery swapping station being triggered, a gas fire extinguishing agent is released in the corresponding compartment or area; in response to the release of the gas fire extinguishing agent inside the battery swapping station, the no-entry warning lights and audible and visual alarms are triggered.

[0070] In addition, fire hoses can be deployed at the top inside each compartment, and each compartment and each area inside the battery swapping station are separated by firewalls.
