Description

Technical Field

[0001] This invention relates to the field of electric self-balancing scooter technology, and more specifically to a dedicated storage and charging device for electric self-balancing scooters. Background Technology

[0002] Electric self-balancing scooters are personal short-distance transportation tools powered by electricity and capable of self-balancing. They are also known as self-balancing vehicles, scooters, or self-balancing scooters. They use built-in precision gyroscopes and accelerometers to detect changes in the vehicle's posture in real time, and a high-speed microprocessor calculates and adjusts the motor output to achieve automatic balance. With the continuous maturation of electric self-balancing scooter technology, their ease of operation and use have led to their widespread application across various industries. For example, in airport terminals, various support units are increasingly equipping themselves with electric self-balancing scooters, primarily for employee work, smart baggage handling, and special services. These scooters expand the service radius of staff by 3-5 times, increasing overall work efficiency by 40-60%. Simultaneously, they free up passengers' hands, significantly reducing walking distance and passenger fatigue within the terminal. Furthermore, they enable some passengers with special needs to use self-service, freeing up significant manpower to serve passengers with greater needs.

[0003] While electric self-balancing scooters improve work efficiency, they also bring new risks: They are powered by lithium batteries, which pose a risk of spontaneous combustion, and extinguishing such fires is difficult. To address these risks, patent CN213845424U discloses an electric self-balancing scooter lithium battery with a fire-retardant device. Through the combined use of a protective frame, through-holes, and a fire extinguishing bag, the high temperature generated by the lithium battery can be conducted to the protective frame through multiple through-holes. This allows the fire extinguishing bag above the frame to be heated by the lithium battery. Furthermore, when the fire extinguishing bag melts and ruptures, the extinguishing agent inside can quickly fall through the through-holes to the lithium battery, accelerating fire suppression and preventing the spread of the fire, thus giving the lithium battery a fire-retardant function. Secondly, the combined use of a condenser pipe, inlet pipe, and outlet pipe allows the heat generated by the lithium battery during operation to be absorbed by the condenser pipe, achieving water cooling and lowering the battery temperature. The vacuum environment inside the condenser pipe lowers the boiling point of the liquid inside, resulting in faster condensation and cooling, thus giving the lithium battery a condensation and cooling function.

[0004] Although the above-mentioned device has fire prevention function, it still has certain problems: 1) The above-mentioned device requires non-standard modification of lithium batteries, which poses a risk of affecting the normal use of lithium batteries; 2) The entire device increases the weight of lithium batteries, which increases the burden on users in terms of use, storage and charging; 3) Lithium batteries burn quickly when they catch fire, and there is no time for the matching fire extinguishing agent to take effect, which may lead to the spread of fire. The above-mentioned device has a slow response and is difficult to meet the actual use needs. Summary of the Invention

[0005] This invention provides a dedicated storage and charging device for electric self-balancing scooters, which solves the technical problems of existing electric self-balancing scooters with fire prevention devices increasing the burden on users and making it impossible to quickly and safely extinguish fires in the event of a fire during storage or charging.

[0006] To solve the above problems, the electric balance scooter-specific storage and charging device provided by the present invention adopts the following technical solution: A dedicated storage and charging device for electric balance vehicles includes a housing, which has independent charging compartments, a water tank, and an electromechanical compartment. The charging compartment is used to store electric balance vehicles. It has a positioning component for positioning electric balance vehicles. The charging compartment has an openable and closable door that closes after the electric balance vehicle is placed in, forming a sealed fireproof space. The charging compartment is also equipped with smoke detectors. The water tank has an outlet connected to the charging compartment and a power component for pumping water inside. The electromechanical compartment has a plug for connecting to a fixed power source and a charging socket, the charging socket being connected to the charging components of the self-balancing vehicle. The electromechanical compartment has a control circuit that connects the smoke detector and the power unit, and is also connected to a circuit breaker to control the power unit to add water to the charging compartment and disconnect the power supply when a fire is detected.

[0007] The beneficial effects of the electric balance scooter storage and charging device provided by this invention are as follows: The charging compartment, water tank, and electromechanical compartment are set up independently, eliminating the need for non-standard modifications to the electric balance scooter's lithium battery. This avoids the problems of battery modification affecting usability and increasing weight in existing technologies, reducing the burden on users in terms of use and storage. The charging compartment can open and close its door to form a sealed space. Combined with smoke detectors, this prevents the spread of smoke in the early stages of a fire and quickly detects fire signals. The control circuit links the smoke detector, power components, and circuit breaker, enabling rapid power cut-off and water injection in case of fire. Through water cooling, suffocation, and air isolation (the most effective fire extinguishing method for lithium batteries), the battery is completely submerged in a short time, achieving fire extinguishing. Finally, the independent compartment design avoids mutual interference between charging, fire extinguishing, and electromechanical control components, reducing the risk of short circuits caused by improper charging.

[0008] In summary, through the above-mentioned design, the present invention can intelligently and safely realize the storage and charging of electric balance vehicles, solving the technical problems of existing electric balance vehicles with fire prevention devices increasing the burden on users and making it impossible to quickly and safely extinguish fires in the event of a fire during storage or charging.

[0009] Furthermore, the front of the enclosure is the charging compartment, and the rear is the water tank and the electromechanical compartment. The upper parts of the water tank and the electromechanical compartment are flush, and their heights are both higher than the charging compartment, so that the overall enclosure has an L-shaped structure.

[0010] The advantages of the above solution are: the L-shaped structure is compact, requires no additional space, and is suitable for scenarios where there is no centralized charging location and a decentralized layout is required.

[0011] Furthermore, the enclosure is made of stainless steel, and the charging compartment, water tank, and electromechanical compartment are all rectangular, formed by welding.

[0012] The advantages of the above solution are: the stainless steel structure has high strength and high temperature resistance; the welded rectangular chamber has strong sealing properties, which can prevent fire from breaking through the chamber and spreading, and, together with the airtightness of the charging chamber, block the spread of smoke. At the same time, stainless steel is stable and durable, and is a general-purpose material, making spare parts easy to procure and reducing long-term operating costs.

[0013] Furthermore, the bottom of the charging compartment has a convex platform, the upper end of which is used to support the base of the electric balance vehicle, and the two sides of the convex platform and the inner wall of the charging compartment form a suspended area for placing the wheels of the electric balance vehicle.

[0014] The beneficial effects of the above solution are: the convex platform supports the electric balance scooter base, ensuring proper placement of the vehicle and good contact between the charging components and the charging socket; at the same time, the suspended areas on both sides allow the wheels to be removed from the contact surface, limiting vehicle displacement, preventing short circuits in the circuit from causing false starts during a fire, and preventing the vehicle from leaving the charging compartment and causing the fire extinguishing system to fail.

[0015] Furthermore, there are gaps between the wheels of the electric balance vehicle and the inner walls of the charging compartment to prevent the wheels from rotating and causing the entire compartment to tip over in the event of a fire and short circuit.

[0016] The beneficial effects of the above solution are: the distance between the wheels and the inner wall further prevents the wheels from rotating and touching the inner wall when a fire or short circuit occurs, preventing the box from being knocked over and preventing the fire from spreading to surrounding items due to the box tipping over, thus reducing the risk of property damage; the vehicle position is fixed and there are no stress points in contact with the inner wall, ensuring that the water flow evenly covers the battery when water is injected, thus improving the fire extinguishing efficiency.

[0017] Furthermore, the upper cover of the charging compartment consists of two doors. On the opposite side of the two doors, there is a channel for the operating rod of the electric balance vehicle to extend. The inner wall of the channel is densely covered with flexible rubber strips that fill the channel. This seals the channel without affecting the passage of the operating rod, thereby improving the airtightness of the charging compartment.

[0018] The beneficial effects of the above solution are: the channel design allows the operating rod to extend, and the charging can be stored without disassembling the operating rod, improving the convenience of use; the flexible rubber strip filling the channel enhances the airtightness of the charging compartment without affecting the use, blocking smoke leakage; and the sealed channel reduces the oxygen flow in the compartment, slowing down the initial combustion speed of the fire, buying time for subsequent water injection and fire extinguishing, and preventing the rapid spread of smoke.

[0019] Furthermore, the power component is a water pump.

[0020] Furthermore, the control circuit employs a microcontroller to provide control signals to the control relays of the circuit breaker and the water pump.

[0021] The beneficial effects of the above scheme are: the control circuit with the microcontroller as its core can quickly process smoke detector signals and accurately output control commands for circuit breakers and water pump relays.

[0022] Furthermore, the control circuit employs an intermediate relay to control the circuit breaker and the water pump, and a 12V DC power supply is used to power the intermediate relay.

[0023] The advantages of the above solution are: the 12V DC power supply provides a safe voltage, avoiding the risk of electric shock or short circuit in the control circuit itself; the intermediate relay transmits signals stably and is a general electrical component, which is convenient to purchase and inexpensive, reducing the overall manufacturing and maintenance costs of the device.

[0024] Furthermore, the control circuit is also connected to an audible and visual alarm to alert staff to a fire.

[0025] The beneficial effects of the above scheme are: the sound and light alarm will quickly issue a warning in the event of a fire, reminding staff to deal with the situation in time or escape, preventing irrelevant personnel from approaching, and preventing the fire from spreading or causing smoke inhalation injury.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The principles and spirit of the present invention will be explained in detail below with reference to several representative embodiments.

[0030] Embodiments of the electric balance scooter storage and charging device provided by the present invention: like Figures 1 to 5 As shown, the electric balance vehicle's dedicated storage and charging device includes a box 1, with casters at the bottom of the box 1, and the box 1 has an independent charging compartment 2, a water tank 3, and an electromechanical compartment 4.

[0031] The charging compartment 2 is used to store the electric balance vehicle 5. It has a positioning component for positioning the electric balance vehicle 5. The charging compartment 2 has an openable and closable door 15, which closes after the electric balance vehicle 5 is placed inside, forming a sealed fireproof space. The charging compartment 2 is also equipped with a smoke detector, which is a smoke alarm 6. The water tank 3 has a water outlet 7 connected to the charging compartment 2 and a power component for pumping water, which is a water pump.

[0032] The electromechanical compartment 4 has a plug for connecting to a fixed power source and a charging socket 9, which is connected to the charging assembly of the electric self-balancing vehicle 5. The electromechanical compartment 4 has a control circuit connected to the smoke detector and the power assembly, and also includes a circuit breaker to control the power assembly to add water to the charging compartment 2 and disconnect the power supply when a fire is detected. A button 8, a reset button, is also located on the top of the electromechanical compartment 4. A normal indicator light 20 and a fault indicator light 21 are located next to the reset button.

[0033] like Figure 1and Figure 2 As shown, the front of the housing 1 is the charging compartment 2, and the rear is the water tank 3 and the electromechanical compartment 4. The upper parts of the water tank 3 and the electromechanical compartment 4 are flush, and their height is higher than that of the charging compartment 2, so that the housing 1 has an overall L-shaped structure. The L-shaped structure is compact, requires no additional space, and is suitable for scenarios where there is no centralized charging location and a distributed layout is required. Figure 2 As shown, a wall panel 19 is attached to the rear side of the enclosure 1 to facilitate the connection of the socket on the wall panel 19 with the plug of the electromechanical compartment 4 to achieve power supply.

[0034] In this embodiment, the housing 1 is made of stainless steel, and the charging compartment 2, water tank 3, and electromechanical compartment 4 are all rectangular, formed by welding. Stainless steel has high structural strength and high temperature resistance, and the welded rectangular housing has strong sealing properties, which can prevent fire from spreading through the housing 1 and, together with the airtightness of the charging compartment 2, block the spread of smoke. At the same time, stainless steel is stable and durable, and is a general-purpose material, making spare parts easy to procure and reducing long-term operating costs.

[0035] In other embodiments, flame-retardant materials may be arranged on the inner wall of the charging compartment 2 to further reduce the risk of fire spread.

[0036] like Figure 4 As shown, the bottom of the charging compartment 2 has a convex platform 11. The upper surface of the convex platform 11 is used to support the base 12 of the electric balance scooter 5. The two sides of the convex platform 11 and the inner wall of the charging compartment 2 form a suspended area 14 for placing the wheels 13 of the electric balance scooter 5. The convex platform 11 supports the base 12 of the electric balance scooter 5, ensuring that the vehicle is placed properly and that the charging components make good contact with the charging socket 9. At the same time, the suspended areas 14 on both sides allow the wheels 13 to be separated from the contact surface, restricting the displacement of the vehicle, preventing short circuits in the event of a fire that could cause false starts, and preventing the vehicle from falling out of the charging compartment 2 and causing the fire extinguishing system to fail.

[0037] Furthermore, there are gaps between the wheels 13 of the electric balance scooter 5 and the inner walls of the charging compartment 2 to prevent the wheels 13 from rotating and causing the entire compartment 1 to tip over in the event of a fire and short circuit. The gaps between the wheels 13 and the inner walls further prevent the wheels 13 from rotating and touching the inner walls in the event of a fire and short circuit, preventing the compartment 1 from tipping over and avoiding the spread of fire to surrounding items due to the compartment 1 tipping over, thus reducing the risk of property damage. The vehicle's fixed position and absence of any stress points in contact with the inner walls ensure that water flows evenly over the battery during water injection, improving fire extinguishing efficiency.

[0038] When the water overflows the wheel 13, even if the wheel 13 short-circuit and rotates, it will only splash water around, further improving the fire extinguishing effect.

[0039] like Figure 3As shown, the upper cover of the charging compartment 2 is composed of two doors 15. On the opposite side of the two doors 15, there is a channel 16 for the operating rod 18 of the electric balance vehicle 5 to extend. The inner wall of the channel 16 is densely covered with flexible rubber strips 17 that fill the channel 16. While not affecting the passage of the operating rod 18, the channel 16 can be sealed to improve the airtightness of the charging compartment 2.

[0040] The design of channel 16 allows the operating lever 18 to extend, enabling storage and charging without disassembling the operating lever 18, thus improving ease of use. The flexible rubber strip 17 fills channel 16, enhancing the airtightness of the charging chamber 2 without affecting its use and preventing smoke leakage. Furthermore, sealing channel 16 reduces oxygen flow within the chamber, slowing down the initial combustion rate of a fire and buying time for subsequent water injection for fire extinguishing, thus preventing the rapid spread of smoke.

[0041] like Figure 5 As shown, in this embodiment, the control circuit has two forms. One is a control circuit using a microcontroller to provide control signals to the control relays of the circuit breaker and the water pump. The microcontroller-based control circuit can quickly process smoke detector signals and accurately output control commands to the circuit breaker and the water pump relays.

[0042] Another approach is to use intermediate relays in the control circuit to control the circuit breaker and water pump. These intermediate relays are powered by a 12V DC power supply. The 12V DC power supply provides a safe voltage, preventing the control circuit itself from experiencing electric shock or short circuit risks. The intermediate relays transmit stable signals and are general-purpose electrical components, making them easy to procure and inexpensive, thus reducing the overall manufacturing and maintenance costs of the device.

[0043] Finally, the control circuit is also connected to an audible and visual alarm 10 to alert staff to a fire. The audible and visual alarm 10 will quickly sound an alarm in the event of a fire, prompting staff to take timely action or escape, preventing unauthorized personnel from approaching, and preventing the fire from spreading or causing smoke inhalation injuries.

[0044] It should be noted that in other embodiments, this device can also be modified in a conventional way, such as using a transparent shell material to enhance visibility, adding a power management module to enable timed charging and automatic power-off functions, and adding a fixed water source interface and solenoid valve control device to remove the water tank 3 and reduce the size.

[0045] The working principle of the electric balance scooter storage and charging device provided by this invention is as follows: When using the electric balance scooter 5 storage and charging device, first observe whether the shell status indicator light and the water level of the water tank 3 are normal. After confirming that there are no problems, open the two side doors 15 of the charging compartment 2, place the electric balance scooter 5 on the convex platform 11 inside the compartment, so that the wheels 13 are in the suspended area 14 on both sides and keep a distance from the inner wall. The operating rod 18 extends through the channel 16 of the door 15 (the channel 16 is sealed by a flexible rubber strip 17). Then connect the charger and the charging socket 9, and close the door 15 to start charging.

[0046] If a fire occurs during charging or storage, the smoke detector inside the compartment (typically with a sensitivity of 0.5 dB / m) will quickly detect the smoke signal and transmit it to the control circuit of the electromechanical compartment 4. The control circuit will simultaneously trigger three actions within 0.1 seconds: First, it will cut off the charging circuit through the circuit breaker to prevent the power supply from exacerbating the fire; second, it will start the high-flow water pump in the water tank 3 (this device uses a 30 L / MIN water pump) to inject water into the charging compartment 2 through the outlet 7. Within 15 seconds, the lithium battery will begin to be submerged, and within 35 seconds, it will be completely submerged to form a physical barrier, achieving efficient fire extinguishing through cooling, suffocation, and air isolation; third, it will activate the top audible and visual alarm 10 to promptly remind staff to take action or escape. Meanwhile, the sealed structure of the charging compartment 2, the stainless steel material, and the sealing design of the flexible rubber strip 17 can effectively block the spread of smoke and fire. The suspended and limited design of the wheels 13 prevents the vehicle from accidentally starting and leaving the compartment due to short circuit, further preventing the fire from spreading. After the fire is extinguished, the staff can restore the device to normal use by manually resetting the button. The whole process does not require manual intervention in the core fire extinguishing steps and is suitable for various scenarios such as decentralized charging and unattended operation.

[0047] Based on the above description in this specification, those skilled in the art will also understand that the following terms, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0048] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
