Emergency starting power supply capable of stabilizing output power

Abstract

The invention relates to the technical field of vehicle-mounted emergency starting power supplies, in particular to an emergency starting power supply capable of stabilizing output power, which comprises a starting battery and a shell, the shell is provided with a plug, a first interface, a waterproof assembly, a heat dissipation assembly and an illumination assembly, and the heat dissipation assembly comprises a heat dissipation fan and a plurality of graphene patches. By means of the waterproof assembly, when the emergency power supply is in rainy days, rainwater is not prone to flowing into the first interface, the interior of the emergency power supply is kept dry, the situation that dust or moisture enters the first interface to cause damage is avoided, and the service life of the starting battery is prolonged; graphene is high in heat conductivity coefficient, rapid in heat dissipation and good in flexibility, the size of the starting power supply is reduced, the starting power supply is convenient to carry, more starting batteries can be contained, the power carrying capacity of the emergency power supply is increased, outdoor use is facilitated, and heat absorbed by graphene can be better dissipated through assistance of a cooling fan.

Description

technical field [0001] The invention relates to the technical field of vehicle emergency starting power supply, in particular to an emergency starting power supply with stable output power. Background technique [0002] The car emergency start power supply is a multi-functional and portable mobile power supply developed for car lovers and business people who travel by car; The emergency power supply is used to charge the car battery to start the car.

[0002] The car emergency start power supply is a multi-functional and portable mobile power supply developed for car lovers and business people who travel by car; The emergency power supply is used to charge the car battery to start the car. The traditional car emergency start power supply is often placed in the trunk of the car. Dust or moisture can easily damage the power interface. At the same time, when using the emergency power supply in some rainy and snowy weather, due to The interface is exposed to rain, which leads to the need to dry the power supply to connect to the car battery, which is inconvenient to operate, and at the same time reduces the life of the vehicle emergency starter power supply, and when the external wire is connected to the power interface, the connection is prone to instability, resulting in insufficient output power. Stable, causing damage to the car; at the same time, when the vehicle emergency starter power is used for a long time at high power, it will generate heat, which will affect its service life

[0003] Chinese patent CN202023177442.3 discloses a vehicle-mounted emergency start-up power supply with stable output power. The external wiring of the vehicle-mounted emergency start-up power supply is fixed through the structure of an electric push rod, a baffle and a limit slot, and the cooperation of the cooling water pipe and the fan For the heat dissipation of the vehicle emergency start power supply, although this patent solves the problems of external line fixing and power supply heat dissipation, water cannot be released from the interface. For the operation of the car; the design of its heat dissipation water pipe can play a role in heat dissipation, but it will occupy a large space and increase the volume of the vehicle emergency start power supply, which is not conducive to carrying
