Description

Technical Field

[0001] The utility model relates to the field of storage batteries, in particular to a fireproof outdoor mobile power source. Background Art

[0002] Energy storage power supply, or outdoor power supply, is a large-capacity portable energy storage device. Its structure is usually a protective shell on the outside, with energy storage components inside the shell. The energy storage components usually include functional components such as batteries and circuit boards. The energy storage components are used to store electrical energy and control charging and discharging. The energy storage components are provided with an input part for establishing a connection for charging the energy storage components. For example, the input part is a mains socket that can be connected to the mains to charge the energy storage components. The energy storage components are provided with an output part for establishing a connection for powering external devices. For example, the output part is a 5V DC USB charging port that can charge mobile phones, and another example is a 220V AC socket that can power small appliances. Energy storage power supplies are particularly suitable for self-driving travel and can be carried for outdoor camping. The current outdoor energy storage power supply can be directly brought outdoors for power supply use. Therefore, during the use of the outdoor energy storage power supply, the wires need to be connected to the outdoor energy storage power supply. When the outdoor energy storage power supply encounters rainy weather, the connection between the wires and the outdoor energy storage power supply is easily affected by the rainy weather. For example, rain falls on the connection between the wires and the outdoor energy storage power supply, which causes the wire connection to be unstable. At the same time, there is a risk of fire during the use of the outdoor energy storage power supply. The current outdoor energy storage power supply itself does not have the function of extinguishing fire. When the outdoor energy storage power supply catches fire, it can only be extinguished by external force. This method requires the user to be close to the outdoor energy storage power supply, but the energy storage power supply that has caught fire is at risk of explosion.

[0003] To solve the above problems, the prior art provides many solutions, such as the existing patent WO2022134748A1, which provides a lithium battery explosion-proof box device, which provides a lifting plate solution to ensure the safety of the battery pack, and the battery pack of the device is equipped with a fire extinguishing sticker that can automatically extinguish a fire. However, the above patent still has room for improvement in how to ensure the stability of the battery and efficiently extinguish the fire of the battery. Utility Model Content

[0004] The utility model aims to provide a fireproof outdoor mobile power supply, which can improve the stability of the battery, protect the battery, and can timely control the temperature and direction of the fire and extinguish the fire in the battery.

[0005] In order to solve the above technical problems, the utility model specifically provides the following technical solutions: a fireproof outdoor mobile power supply, including a base, a first cavity is provided in the center of the base, the first cavity is connected with any end surface of the base, a single-core battery is placed in the first cavity, and the base is provided with at least two first jacks around the first cavity, and a fire extinguishing patch capable of suppressing thermal runaway and extinguishing fire is placed in the first jack. By placing the single-core battery in the first cavity in the base, the base is used to protect the outside of the single-core battery, and for outdoor use environments, the single-core battery can be better protected from being damaged or flooded, and the placement stability of the single-core battery can be relatively improved.

In addition, the first partition separates the single-core batteries to avoid the risk of overheating when the single-core batteries are placed adjacently, and the first partition is made of materials that can suppress thermal runaway and extinguish fire, so that the single-core batteries have temperature control and fire extinguishing effects. In addition, in the case of external impact damaging the matrix, the first partition can assist in absorbing the impact force and reduce the damage of the impact force to the single-core battery.

[0010] According to an embodiment of the utility model, the first partition has a first plate body relative to the single-cell battery and / or the wall of the first cavity, and the surface of the first plate body is connected to the second plate body through an elastic member. The second plate body is arranged to abut against the surface of the single-cell battery on the side of the first partition, so that a gap is left between the first partition and the single-cell battery to ensure the normal heat dissipation of the single cell, and the elastic member can always ensure the contact between the second plate body and the single-cell battery, thus ensuring the stability between the single-cell battery and the first partition, and for the single-cell battery placed inside the first cavity, the spacing between each other and the relatively stable state can be guaranteed.

[0011] According to an embodiment of the utility model, a second cavity is provided in the first substrate, and the second cavity is arranged around the first cavity.

[0012] According to one embodiment of the utility model, a vertically placed second partition is provided in the second cavity, and third partitions capable of abutting against the wall of the second cavity are arranged in arrays on both sides of the second partition. Through holes are opened on the surface of the third partition and a first fastener connected to the second partition is provided, and adjacent third partitions are connected by the second fastener; the abutment of the third partition can absorb external collision force, and the third partition has fire extinguishing ability, which can control and extinguish the fire inside the base, and the third partition adopts an array layout scheme, and the number of third partitions to be used can be freely selected according to the situation.

[0013] An opening and closing plate corresponding to the position of the second cavity is provided at the upper end of the base body, which is used to open or close the second cavity, so as to facilitate taking and placing of substances in the second cavity.

[0014] According to one embodiment of the utility model, a pad is attached to the side of the third partition. The pad is provided to improve the flatness of the third partition and reduce the extrusion damage of the fasteners to the side of the third partition, especially to prevent or avoid leakage of the fire extinguishing medium inside the third partition.
