[0002] With the rapid development of electric vehicles and the restriction of motorcycles in some cities, electric two-wheelers have become widespread. As a basic delivery tool for the food delivery and courier industries, electric two-wheelers need to have long range, long service life, and light weight. Lithium-ion batteries, with their high operating voltage, high energy density, good safety, light weight, low self-discharge, long cycle life, and pollution-free characteristics, can serve as a power source for electric two-wheelers. Electric vehicle charging and swapping stations are indispensable energy service infrastructure for the large-scale industrialization of electric vehicles, meeting the needs of the development of new energy electric vehicles and accommodating flexible daily electricity usage.

[0003] Currently, most battery swapping cabinets for two-wheeled electric vehicles on the market place the battery pack inside the compartment and connect it to a charging cable for wired charging. In the event of a dangerous situation (such as battery overheating, thermal runaway, or deflagration), the traditional fire suppression method for these cabinets is to activate an aerosol device inside the compartment, which consumes oxygen to suppress the flames. However, in practical applications, due to the unique characteristics of lithium batteries, once a lithium battery deflagrates, fire suppression measures such as sprinklers are simply insufficient to extinguish the flames. Since the lithium battery remains inside the swapping cabinet, it can easily cause thermal runaway in other lithium batteries, further increasing the damage. Summary of the Invention

[0004] This invention provides a wireless charging battery swapping cabinet equipped with a fireproof box, which solves the problem in the prior art that lithium batteries can easily suffer thermal runaway and combustion in the battery swapping cabinet, leading to further losses.

[0016] Figure 2 This is a schematic diagram of the control structure in this utility model. Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] In the technical solution of this utility model, Figure 1 and Figure 2 This is a structural diagram illustrating the specific structure of a wireless charging and battery swapping cabinet equipped with a fireproof box according to this utility model. Figure 1 and Figure 2 As shown, this utility model includes:

[0019] The cabinet 1 and the fireproof box 3 are provided. The cabinet 1 is provided with multiple battery compartments 2. The front of the battery compartment 2 is provided with an openable front door 11. The front door 11 is provided on the front panel of the cabinet 1. The battery compartment 2 is inclined downward. The back of the battery compartment 2 is provided with a rear door 21. The rear door 21 is provided on the rear panel of the cabinet 1.

[0020] The rear door 21 is equipped with a transmitting coil 23, and the top of the battery compartment 2 is equipped with a wireless charging transmitting module 22. The wireless charging transmitting module 22 is electrically connected to the transmitting coil 23. The bottom surface of the rear door 21 is equipped with a rear door electromagnetic lock 24, which can fasten the rear door 21 to the rear panel of the cabinet 1.

[0021] The fireproof box 3 is located behind the cabinet 1. The top of the fireproof box 3 is provided with a one-way opening door 31 and an opening and closing door electromagnetic lock 34. The fireproof box 3 is equipped with an automatic fire extinguishing device 32 and a lithium battery fire extinguishing fluid 33.

[0022] The fireproof box is made of fireproof and heat-insulating materials, which prevents the temperature and flames of the burning lithium battery from spreading to the battery swapping cabinet, thus minimizing losses.

[0023] The rear door is higher than the one-way door to allow the battery pack to fall from the battery compartment into the fireproof box. In actual installation, the fireproof box can be fixed to the ground or partially embedded in the ground. When the fireproof box is fixed to the ground, to ensure that the combustion of the battery pack 6 in the fireproof box 3 will not affect the battery swapping cabinet, heat insulation material 5 is installed between the fireproof box 3 and the cabinet body 1.

[0024] The wireless charging transmitter module 22, the rear door electromagnetic lock 24, and the opening and closing door electromagnetic lock 34 are all communicatively connected to the battery swapping cabinet controller 4.

[0025] The transmitting coil 23 and the wireless charging transmitting module 22 work together to charge the battery pack 6, which is equipped with a wireless receiving module and a receiving coil. The battery pack 6 uses wireless charging technology, with the receiver built into its bottom. The battery pack 6 communicates with the battery swapping cabinet in real time via wireless communication, transmitting charging data in real time. It should be noted that both the wireless charging module and the wireless transmitting module in the wireless charging technology are conventional technologies in this field, and therefore will not be described in detail here. The wireless charging module transmits electrical energy to the transmitting coil, which then transmits the electrical energy.

[0026] Wireless charging technology eliminates the need for wired charging cables, allowing the battery pack 6 to be safely charged in the battery compartment without any wiring. Unlike the traditional horizontal placement of the battery pack 6, the battery compartment is tilted downwards at a certain angle, allowing the battery pack 6 to slide freely to the bottom and approach the wireless charging module when placed inside.

[0027] The rear door panel of the battery compartment is equipped with an electromagnetic lock, which can be unlocked by the cabinet controller. During battery charging, the battery swapping cabinet controller receives various charging data sent by the battery pack 6 in real time. If any data abnormality occurs or a dangerous situation arises, the battery swapping cabinet can control the electromagnetic lock at the rear of the battery compartment to unlock automatically, and the battery pack 6 can freely exit the battery compartment and slide into the fireproof box at the rear of the battery swapping cabinet.

[0028] It is important to note that Figure 1 This is for illustrative purposes only and does not accurately represent the proportions of the actual product. In the actual production process, the proportions will vary. Figure 1 The battery pack inside is smaller than the size of the one-way opening door, and the overall size of the fireproof box can be set according to the actual situation.

[0029] Specifically, the top of the fireproof box is hinged with a one-way door, so that the door of the fireproof box can only be opened downwards. At the same time, a torsion spring is installed at the hinge between the fireproof box and the one-way door so that the one-way door can return to its original position after being opened.

[0030] The fireproof box is located behind the battery swapping cabinet and features a one-way door. It also has an electromagnetic lock, which is connected to the battery swapping cabinet's controller. When the controller detects an anomaly, it unlocks both the electromagnetic lock at the rear of the battery compartment and the electromagnetic lock on the fireproof box, allowing the battery pack 6 to slide directly into the fireproof box after being removed from the charging compartment. The fireproof box can contain a certain amount of lithium battery extinguishing fluid to soak any exploding battery pack 6. An automatic fire extinguishing device can also be installed in the fireproof box to extinguish the fire on the battery pack 6 and reduce its intensity. The automatic fire extinguishing device 32 is preferably an aerosol fire extinguishing device. The lithium battery extinguishing fluid can be water or other extinguishing agents effective against lithium battery fires.

[0031] It is important to note that Figure 1 Only one battery compartment is shown in the figure. The specific number of battery compartments can be set according to the user's actual situation. Electromagnetic locks are a conventional technical means in this field, so the structure is not shown in detail in the figure. Those skilled in the art can select the appropriate electromagnetic lock according to actual needs.

[0032] In one embodiment of this utility model, a temperature sensor 25 and a smoke sensor 26 are provided inside the battery compartment 2, and the temperature sensor 25 and the smoke sensor 26 are connected to the battery swapping cabinet controller 4. This configuration is redundant; if the temperature sensor 25 and the smoke sensor 26 detect that the temperature and smoke exceed preset values, the controller will also unlock the rear compartment door electromagnetic lock and the opening / closing door electromagnetic lock.

[0033] In one embodiment of this utility model, the rear compartment door 21 includes: a battery baffle 211 and a cabinet door 212. The top end of the battery baffle 211 and the top end of the cabinet door 212 are connected to each other. The battery baffle 211 and the cabinet door 212 are set at an angle. The rear end of the battery compartment 2 is connected to the rear panel of the cabinet 1. The cabinet door 212 is hinged to the rear panel of the cabinet 1. The transmitting coil 23 is installed on the back of the battery baffle 211.

[0034] When the rear door is closed, the battery baffle is perpendicular to the bottom of the battery compartment, which limits the battery pack 6. At the same time, when the battery pack 6 slides down in the battery compartment, it will come into contact with the battery baffle. At this time, the transmitting coil behind the battery baffle can connect with the receiving coil at the bottom of the battery pack 6 for charging.

[0035] In one embodiment of the present invention, in order to ensure that the battery pack 6 can slide smoothly in the battery compartment, a pulley assembly 27 is provided on the bottom plate of the battery compartment 2.

[0036] In one embodiment of this utility model, the top of the fireproof box 3 is provided with a centrally inclined slide 35, and the one-way opening and closing door 31 is located at the center of the top of the fireproof box 3. This slide ensures that the battery pack 6 can stably slide into the fireproof box after being removed from the battery compartment, preventing the battery pack 6 from burning on the outside.

[0037] This invention utilizes wireless charging technology, ensuring that the battery pack 6 is not connected by any cables during charging. In dangerous situations, the battery pack 6 can be directly ejected from the battery compartment without being prevented from detaching due to the charging cable. Secondly, a fireproof box is added at the rear of the battery swapping cabinet. The rear door of the battery compartment uses an electromagnetic lock; when the electromagnetic lock is opened, the battery pack 6 can freely exit from the battery compartment and slide into the fireproof box at the rear. This invention not only increases the safety of the battery swapping cabinet during operation but also significantly reduces losses caused in dangerous situations.

[0038] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
