Description

Technical Field

[0001] This utility model belongs to the field of battery swapping cabinet technology, specifically relating to an intelligent battery swapping cabinet structure. Background Technology

[0002] With the widespread adoption of electric vehicles, drones, and other devices, smart battery swapping cabinets, which provide rapid battery replacement services, have become widely used. Existing smart battery swapping cabinets are mostly square-shaped structures, with the internal battery compartment typically fixed within the cabinet frame. This traditional structure has gradually revealed the following significant drawbacks during actual operation and maintenance: When a single battery compartment unit or its associated charging interface and connecting lines malfunction, complex disassembly operations are required on-site by professional technicians, a cumbersome and time-consuming process. This not only leads to prolonged downtime of the battery compartment and reduces the service capacity of the cabinet, but also seriously impacts the user's battery swapping experience and the operator's overall service efficiency.

[0003] Lithium-ion batteries pose a risk of thermal runaway and even combustion and explosion under abnormal conditions such as overcharging and short circuits. Although most battery swapping cabinets currently use flame-retardant materials, they lack active and efficient physical isolation mechanisms. Once a fire breaks out in one of the battery compartments, the resulting high-temperature flames and toxic gases can easily spread rapidly within the sealed cabinet, triggering a chain reaction in adjacent battery compartments, potentially leading to the entire cabinet burning down and posing a serious threat to the safety and property of the surrounding public.

[0004] To address this, we propose an intelligent battery swapping cabinet structure. This device not only significantly reduces maintenance time and improves operational efficiency, but also effectively isolates the impact of flames and explosion shock waves inside the cabinet on the outside world through protective components, protecting the safety of surrounding personnel and property. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent battery swapping cabinet structure. This device can not only greatly shorten maintenance time and improve operational efficiency, but also effectively isolate the impact of flames and explosion shock waves inside the cabinet on the outside world through protective components, thus protecting the safety of surrounding personnel and property.

[0006] The specific technical solution adopted by this utility model is as follows: A smart battery swapping cabinet structure includes a cabinet body, which is cylindrical. Multiple threaded mounting slots are arranged in a circumferential array on the outer side of the cabinet body, and a modular battery compartment unit is threaded inside each of the threaded mounting slots. The cabinet is provided with an upper connecting plate and a lower connecting plate at the top and bottom, respectively. A circular groove is provided on the side of the upper connecting plate and the lower connecting plate that are close to each other. A protective component is provided inside the circular groove, and a driving component is provided on the top of the upper connecting plate. The driving component is connected to the protective component.

[0007] Furthermore, the modular battery compartment unit includes a hollow threaded mounting rod installed inside the threaded mounting groove. One end of the hollow threaded mounting rod is fixedly mounted with an independent battery compartment housing, and the other end of the hollow threaded mounting rod is provided with a conductive contact. A connecting wire is provided inside the hollow cavity of the hollow threaded mounting rod. One end of the connecting wire is connected to the conductive contact, and the other end of the connecting wire is connected to a charging plug located inside the battery compartment housing.

[0008] Furthermore, the protective component includes multiple arc-shaped plates disposed inside the circular groove, the width of the multiple arc-shaped plates decreasing sequentially, and each arc-shaped plate is provided with an arc-shaped groove. The corresponding arc-shaped plate is slidably disposed inside the arc-shaped groove, and the outer side of the smallest arc-shaped plate is connected to the drive component.

[0009] Furthermore, each of the arc-shaped grooves has an arc-shaped sliding groove on its inner wall, and an arc-shaped slider is provided inside the arc-shaped sliding groove. One side of the arc-shaped slider is connected to the corresponding arc-shaped plate.

[0010] Furthermore, a high-temperature resistant sealing strip is provided at the joint of each pair of the arc-shaped plates.

[0011] Furthermore, the drive assembly includes a stepper motor disposed on the top of the upper connecting plate, the output end of the stepper motor is mounted with a connecting frame, one end of the connecting frame being connected to the outer side of the smallest arc-shaped plate.

[0012] The technical effects achieved by this utility model are as follows: 1. Through the connection method of threaded mounting rod and threaded mounting groove, any battery compartment unit can be quickly removed and installed like tightening a screw. When a single unit fails, maintenance personnel only need to unscrew the old one and replace it with a spare new unit, which greatly shortens the maintenance time and improves operational efficiency.

[0013] 2. The protective components can effectively isolate the impact of flames and explosion shock waves inside the cabinet on the outside world, protecting the safety of surrounding personnel and property. Attached Figure Description

[0016] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0017] like Figures 1-5 As shown, a smart battery swapping cabinet structure includes a cabinet 1, which is cylindrical. Multiple threaded mounting slots 2 are arranged in a circumferential array on the outer side of the cabinet 1. Each threaded mounting slot 2 is threaded with a modular battery compartment unit inside. The top and bottom of the cabinet 1 are respectively provided with an upper connecting plate 3 and a lower connecting plate 4. A circular slide groove 5 is provided on the side of the upper connecting plate 3 and the lower connecting plate 4 that are close to each other. A protective component is provided inside the circular slide groove 5, and a drive component is provided on the top of the upper connecting plate 3. The drive component is connected to the protective component.

[0018] The cabinet 1 contains modules used in existing battery cabinets, such as a PLC control system, a temperature sensor, and a ring power supply busbar. When the temperature sensor or smoke sensor detects an abnormal signal, the PLC control system triggers a stepper motor to drive the protective components to unfold, and then cuts off the power supply to the corresponding battery compartment after unfolding. This is existing technology and will not be elaborated on here.

[0019] The modular battery compartment unit includes a hollow threaded mounting rod 6 installed inside the threaded mounting groove 2. One end of the hollow threaded mounting rod 6 is fixedly mounted with an independent battery compartment housing 7. The other end of the hollow threaded mounting rod 6 is provided with a conductive contact 8. A connecting wire is provided inside the hollow cavity of the hollow threaded mounting rod 6. One end of the connecting wire is connected to the conductive contact 8, and the other end of the connecting wire is connected to a charging plug 9 located inside the battery compartment housing 7.

[0020] By rotating the battery compartment unit, the hollow threaded mounting rod 6 at its tail is screwed into the threaded mounting groove 2. When tightened to the bottom, the conductive contact 8 on the hollow threaded mounting rod 6 is tightly pressed against the annular power supply busbar installed inside the cabinet 1, forming a stable electrical connection. Power provided by the external urban power grid or the energy storage system inside the cabinet is transmitted to the conductive contact 8 through the power supply busbar. The power is then conducted to the charging plug at the front of the battery compartment unit through the wires built into the hollow threaded mounting rod 6. Finally, the charging plug is inserted into the charging interface of the battery pack inside the battery compartment to start charging or communication.

[0021] It should be noted that the power supply method of the battery compartment 7 is similar to the installation method of light bulbs in existing technology, which is existing technology and will not be elaborated on here.

[0022] The protective component includes multiple arc-shaped plates 10 disposed inside the circular slide groove 5. The width of the multiple arc-shaped plates 10 decreases sequentially, and each arc-shaped plate 10 is provided with an arc-shaped groove 11. The corresponding arc-shaped plate 10 is slidably disposed inside the arc-shaped groove 11, and the outer side of the smallest arc-shaped plate 10 is connected to the drive component.

[0023] In the event of a fire, the drive assembly is activated, which moves the smallest arc-shaped plate 10. Through the interaction of the arc-shaped grooves 11 between each plate, the motion is transmitted sequentially, and each arc-shaped plate 10 extends step by step until all arc-shaped plates 10 are fully unfolded, covering the preset protective area, and closing with the adjacent arc-shaped plates 10 to form a complete cylindrical protective shell.

[0024] Each arc-shaped groove 11 has an arc-shaped sliding groove 12 on its inner wall. An arc-shaped slider 13 is installed inside the arc-shaped sliding groove 12. One side of the arc-shaped slider 13 is connected to the corresponding arc-shaped plate 10. This arrangement not only allows for sliding but also provides a limit to prevent the travel from being exceeded.

[0025] A high-temperature resistant sealing strip is provided at the joint of every two curved plates 10, which can improve the sealing effect.

[0026] The curved plate 10 is composed of a metal shell and an inner fireproof and heat-insulating layer, which gives it high temperature resistance and a certain strength.

[0027] The drive assembly includes a stepper motor 14 mounted on top of the upper connecting plate 3. A connecting frame 15 is mounted on the output end of the stepper motor 14, and one end of the connecting frame 15 is connected to the outer side of the smallest arc plate 10. The arc plate 10 is rotated by the stepper motor 14 driving the connecting frame 15.

[0028] It should be noted that the stepper motor 14 is equipped with a protective cover, which can improve the service life of the stepper motor 14. This is existing technology and will not be elaborated on here. Additionally, to dissipate the heat generated during battery charging, the cabinet 1 can utilize existing technology to create openings and install fans for cooling. The fan and opening configurations are also existing technologies and will not be elaborated on here.

[0029] The working principle of this utility model is as follows: When a modular battery compartment unit needs to be installed or replaced, the maintenance personnel align it with the threaded mounting slot 2 on the cabinet 1. By rotating the battery compartment unit, the hollow threaded mounting rod 6 at its tail is screwed into the threaded mounting slot 2. When it is tightened to the bottom, the conductive contact 8 on the hollow threaded mounting rod 6 is tightly pressed with the annular power supply busbar installed inside the cabinet 1, forming a stable electrical connection. The power provided by the external urban power grid or the energy storage system inside the cabinet is transmitted to the conductive contact 8 through the power supply busbar. The power is then conducted to the charging plug at the front end of the battery compartment unit through the wires built into the hollow threaded mounting rod 6. Finally, the charging plug is inserted into the charging interface of the battery pack inside the battery compartment to start charging or communication. Through the connection method of the threaded mounting rod and the threaded mounting slot 2, any battery compartment unit can be quickly removed and installed like tightening a screw. When a single unit fails, the maintenance personnel only need to unscrew the old one and replace it with a spare new unit, which greatly shortens the maintenance time and improves the operational efficiency. The protective assembly retracts to one side of cabinet 1, exposing the modular battery compartment unit for normal battery replacement. When the fire detection system inside cabinet 1 (such as a temperature sensor, smoke sensor, or battery gas detector) detects signs of thermal runaway in a battery compartment unit (such as a sudden temperature rise or smoke), it immediately sends an alarm signal to the main control system. Upon receiving the signal, the main control system instantly activates the top drive assembly, which outputs torque to unfold the protective assembly, quickly forming a robust, sealed cylindrical protective shell. This shell effectively isolates the flames and blast waves inside the cabinet from the outside environment, protecting the safety of surrounding personnel and property.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
