Description

Technical Field

[0001] This invention relates to the field of battery swapping equipment technology, specifically to a lithium battery swapping cabinet system for electric vehicles. Background Technology

[0002] Electric bicycles are now ubiquitous throughout China, serving as a convenient mode of transportation for daily commutes and finding widespread application in delivery and express shipping industries. This has created a significant demand for charging and battery swapping, leading to the development of battery swapping stations. These stations not only store a certain number of lithium batteries but also have built-in charging capabilities. Users can place depleted batteries into the station and retrieve fully charged ones, achieving a seamless swap without the need to stop for charging.

[0003] However, currently available battery swapping cabinets generally have a battery compartment door at the front and an inspection door at the rear. This means that batteries can be stored and retrieved through the front of the cabinet, while maintenance can be performed through the rear. However, the front area of ​​existing battery swapping cabinets is fixed and small. When one user is replacing a lithium battery, it will block the battery swapping process for other users who need to swap batteries at the same time. This results in low battery swapping efficiency and makes it inconvenient for multiple users to swap lithium batteries simultaneously. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an electric vehicle lithium battery swapping cabinet system, which facilitates simultaneous battery swapping by multiple users, ensuring that multiple users can perform synchronous battery swapping and improving the battery swapping efficiency of the cabinet.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric vehicle lithium battery swapping cabinet system, comprising a swapping cabinet body, a main control module mounted on the swapping cabinet body, and a swapping module, a communication module, and a charging module connected to the main control module;

[0006] The main control module is used to receive and process information, send instructions to the battery swapping module and the charging module, and transmit information through the communication module.

[0007] The battery swapping module connects to the battery swapping device installed on the battery swapping cabinet and sends commands to the battery swapping device to control the lithium batteries placed inside the battery swapping cabinet to swap batteries on the front and / or side of the battery swapping cabinet.

[0008] The charging module is connected to the charging device located inside the battery swapping cabinet and connected to the lithium battery body. It sends instructions to the charging device to control the charging device to charge or maintain the power of the lithium battery body.

[0009] The communication module is used to receive information from clients and terminals and to send information sent from the main control module to clients and terminals.

[0010] The back of the battery swapping cabinet has a storage slot, and a storage door is rotatably connected to the opening of the storage slot; multiple positioning slots are equally spaced along the vertical direction on the bottom wall of the storage slot, and a charging device for charging lithium batteries is installed in the positioning slot; multiple battery swapping ports that communicate with the positioning slots are equally spaced along the length of the positioning slots on the front of the battery swapping cabinet, and a protective door is rotatably installed at the opening of the battery swapping port.

[0011] The battery swapping device includes a control structure installed on the battery swapping cabinet and controlling the opening and closing of the protective door; a moving block that passes through the positioning groove and is fitted to the side of the battery swapping port, with charging slots for placing lithium batteries corresponding to multiple battery swapping ports; and a moving component installed in the positioning groove and controlling the two ends of the moving block to move to the outside of the battery swapping cabinet through two adjacent moving slots. The symmetrical sides of the battery swapping cabinet and adjacent to the positioning grooves are each provided with moving slots that penetrate the interior of the positioning grooves.

[0012] Preferably, the moving component includes a drive screw that passes through a positioning groove along the length of the moving block, a screw nut that is threadedly sleeved on the middle of the drive screw and whose end face is fixedly connected to the middle of the side of the moving block, and a motor that is installed inside the battery swapping cabinet and controls the rotation of the drive screw.

[0013] Preferably, a protective plate is provided inside the moving slot, and a heat dissipation slot is provided on the protective plate that is connected to the interior of the multiple charging slots on the moving block; two protective plates located at both ends of the same moving block are connected by an elastic member passing through the positioning slot, and a rainproof strip located on the heat dissipation slot is provided on the end face of the protective plate away from the battery swapping cabinet.

[0014] Preferably, the elastic element includes a telescopic rod that passes through the positioning groove along the moving block and is fixedly connected to different protective plates at both ends. The telescopic rod includes an extension rod that is set along the length direction of the moving block, passes through the positioning groove, and has one end movably protruding out of the battery swapping cabinet to connect to the protective plate, and an extension arm that is set along the length direction of the moving block, passes through the positioning groove, and has one end movably protruding out of the battery swapping cabinet to connect to another protective plate. One end of the extension rod is movably inserted into the telescopic groove opened at the end of the extension arm, and a return spring with its end fixedly connected to the extension rod is provided on the bottom wall of the telescopic groove.

[0015] Preferably, it also includes a protection module installed on the battery swapping cabinet and connected to the main control module.

[0023] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0024] Please see Figure 1-4 An electric vehicle lithium battery swapping cabinet system includes a swapping cabinet body 1, a main control module installed on the swapping cabinet body 1, and a swapping module, a communication module, and a charging module connected to the main control module.

[0025] The main control module is used to receive and process information, send instructions to the battery swapping module and the charging module, and transmit information through the communication module.

[0026] The battery swapping module is connected to the battery swapping device installed on the battery swapping cabinet 1, and sends instructions to the battery swapping device to control the lithium batteries placed in the battery swapping cabinet 1 to swap batteries on the front and / or side of the battery swapping cabinet 1.

[0027] The charging module is connected to the charging device located inside the battery swapping cabinet 1 and connected to the lithium battery body, and sends instructions to the charging device to control the charging device to charge or maintain the power of the lithium battery body.

[0028] The communication module is used to receive information from clients and terminals and to send information sent from the main control module to clients and terminals.

[0029] like Figure 1-4 As shown, when a user needs to replace the lithium battery in their electric vehicle, the communication module sends the battery swapping information to the main control module on the battery swapping cabinet 1. The main control module uses the charging module to determine if there are any lithium batteries in the battery swapping cabinet 1 that are not fully charged. After confirming the information, the main control module sends feedback to the user via the communication module. If there are no fully charged lithium batteries in the battery swapping cabinet 1, the feedback will also be sent to the user. If the user urgently needs a battery swap, they can come to the battery swapping cabinet. When the user receives the feedback, they go to the battery swapping cabinet 1 and use the battery swapping module to control the battery swapping device, moving the lithium batteries inside the battery swapping cabinet 1 from the front and sides of the cabinet 1 to the outside. This ensures that the battery swapping cabinet 1 can still maintain battery swapping efficiency when it needs to provide battery swapping services to multiple users at once, facilitating simultaneous battery swapping for multiple users and improving the overall battery swapping efficiency.

[0030] like Figure 2As shown, a storage slot 10 is provided on the back of the battery swapping cabinet 1, and a storage door 11 is rotatably connected to the opening of the storage slot 10; multiple positioning slots 12 are equally spaced along the vertical direction on the bottom wall of the storage slot 10, and a charging device for charging lithium batteries is provided in the positioning slots 12; multiple battery swapping ports 2 are equally spaced along the length of the positioning slots 12 on the front of the battery swapping cabinet 1, and a protective door is rotatably provided at the opening of the battery swapping port 2. When the user needs to swap batteries, information is sent to the main control module through the communication module, and the main control module sends an instruction to the battery swapping module to drive the control device to control the protective door 3 to rotate and open, so as to facilitate the user to replace the lithium battery body located in the battery swapping cabinet 1, thereby facilitating the user's battery swapping operation.

[0031] like Figure 3-4 As shown, the battery swapping device includes a control structure mounted on the battery swapping cabinet 1 that controls the opening and closing of the protective door 3; a moving block 7 that passes through the positioning groove 12 and is attached to one side of the battery swapping port 2, with charging slots 8 for placing lithium batteries corresponding to multiple battery swapping ports 2; and a moving component mounted in the positioning groove 12 that controls the moving block 7 to move to the outside of the battery swapping cabinet 1 through two adjacent moving slots 4. Moving slots 4, which are connected to the inside of the positioning groove 12, are provided on the symmetrical sides of the battery swapping cabinet 1 near the positioning groove 12. When the battery swapping module receives instructions from the main control module, in the first scenario where only a single user is swapping lithium batteries, the control module drives the control structure to rotate one of the protective doors 3, thereby facilitating the opening of the battery swapping port 2 and allowing the user to place the charging slots 8. In the first scenario, the lithium battery can be removed, making it convenient for users to replace the battery. In the second scenario, when multiple users need to replace the lithium battery, or when a single user needs to replace the lithium battery while other users need to replace it simultaneously, the moving block 7, which is installed in the positioning slot 12, moves through the moving slot 4 and out of the battery swapping cabinet 1. That is, it moves out to the left and right sides of the battery swapping cabinet 1, thereby moving the lithium battery placed in the charging slot 8 to the outside of the battery swapping cabinet 1. This allows multiple users to replace the lithium battery simultaneously, avoiding the situation where users need to replace the lithium battery and causing queuing. It facilitates simultaneous battery swapping for multiple users, ensuring that multiple users can replace the battery at the same time, and improving the battery swapping efficiency of the battery swapping cabinet.

[0032] like Figure 4As shown, the moving assembly includes a drive screw 13 that passes through the positioning groove 12 along the length of the moving block 7, a screw nut 14 that is threadedly sleeved on the middle of the drive screw 13 and whose end face is fixedly connected to the middle of the side of the moving block 7, and a motor installed inside the battery swapping cabinet 1 to control the rotation of the drive screw 13. The motor is a stepper motor, which facilitates the control of the rotation of the drive screw 13, thereby facilitating the movement of the moving block 4 through the screw nut 14 to pass through the battery swapping cabinet 1. The forward and reverse rotation of the motor facilitates the control of the moving block 7 through the battery swapping cabinet. The left-side moving slot 4 of cabinet 1 extends out of cabinet 1, or the right-side moving slot 4 extends out of cabinet 1, thus preventing the moving blocks 7 from simultaneously extending out of cabinet 1 at adjacent positions on the same side. This ensures that multiple users can replace lithium batteries at the same time, avoiding queuing for lithium battery replacement or one user blocking another user's access space while replacing a lithium battery. This facilitates simultaneous battery replacement for multiple users, ensuring that all users can perform simultaneous battery replacement, and improving the battery replacement efficiency of the cabinet.

[0033] A protective plate 5 is provided inside the moving slot 4, and a heat dissipation slot is provided on the protective plate 5, which is connected to the interior of the multiple charging slots 8 on the moving block 7; two protective plates 5 located at both ends of the same moving block 7 are connected by an elastic member passing through the positioning slot 12, and a rainproof strip 6 located on the heat dissipation slot is provided on the end face of the protective plate 5 away from the cabinet 1.

[0034] like Figure 3-4 As shown, the elastic element includes a telescopic rod 9 that passes through the positioning groove 12 along the moving block 7 and is fixedly connected to different protective plates 5 at both ends. The telescopic rod 9 includes an extension rod that is set along the length direction of the moving block 7, passes through the positioning groove 12, and has one end movably protruding out of the battery swapping cabinet 1 to connect to the protective plate 5; and an extension arm that is set along the length direction of the moving block 7, passes through the positioning groove 12, and has one end movably protruding out of the battery swapping cabinet 1 to connect to another protective plate 5. One end of the extension rod movably passes through the telescopic groove opened at the end of the extension arm, and a return spring with its end fixedly connected to the extension rod is provided on the bottom wall of the telescopic groove. The elastic element is driven by a motor to rotate the lead screw 13, thereby moving the moving block 7. When the moving block 7 moves to the outside of the battery swapping cabinet 1 through the moving slot 4, the protective plate 5 set at the opening of the moving slot 4 will move synchronously with the moving block 7. After the moving block 7 moves into the positioning slot 12, the protective plate 5 will move back into the moving slot 4 under the action of the return spring. A rubber ring is set on the cross-section of the protective plate 5 near the moving slot 4. The protective plate 5 is located in the moving slot 4, which helps to ensure the waterproof performance of the moving slot 4. This prevents raindrops from entering the battery swapping cabinet 1 through the moving slot 4 when it rains outside the cabinet, thus ensuring that the lithium battery in the battery swapping cabinet 1 can be charged and stored normally.

[0035] It also includes a protection module installed on the battery swapping cabinet 1 and connected to the main control module. The protection module is connected to a detection unit, a heat dissipation unit, and a waterproof unit. The detection unit is connected to multiple sensors installed inside the battery swapping cabinet 1 to detect the charging voltage, charging current, charging temperature, and charging humidity of the lithium battery. The heat dissipation unit is connected to the battery swapping cabinet 1 and controls the cooling fan installed at the heat dissipation slot to work. The waterproof unit is connected to a sealing component installed at the opening of the heat dissipation slot and seals the opening of the heat dissipation slot, and controls the sealing component to seal the heat dissipation slot.
