Description

A vehicle emergency power supply

technical field

The utility model relates to a vehicle-mounted emergency power supply, in particular to a handle of the vehicle-mounted emergency power supply.

Background technique

The car emergency power supply is a multi-functional portable mobile power supply developed for car lovers and business people who drive by car. Its special function is to start the car when the car is out of power or unable to start the car for other reasons. At the same time, the air pump is combined with emergency power supply, outdoor lighting and other functions, which is one of the must-have products for outdoor travel.

At present, the car emergency power supply generally does not have a handle on the product, and the portability is not high. Even if there is a handle, the handle does not have a good grip. When it needs to be used, it needs to hold the product by hand, and the comfort is poor. In order to improve the comfort of the product, it is necessary to make a handle to improve the convenience of use.

At present, in the structural design of the battery pack, the vehicle emergency power supply usually only reserves space for a certain capacity and outlet method, and does not consider compatibility in the matching of batteries with different capacities and different outlet methods.

The on-board emergency power supply with its own battery and air pump is used in more and more scenarios in the car. At the same time, it integrates the functions of pumping and ignition to meet the more important needs of the car. However, the volume of the product is not large when these two functions are integrated. It is small and needs to be considered in the internal layout.

At present, the on-board emergency power supply with its own battery and air pump does not have a fan and air duct for heat dissipation, and some use a small axial flow fan. In terms of heat dissipation effect, the problem of the current technology is that the heat dissipation effect is relatively poor, and the heat in the high temperature part of the system cannot be diffused and discharged outside the system in a better time. The problems existing in the current technology are: 1. There is no targeted heat dissipation method for high temperature parts, only in the form of natural convection and axial flow fans, and there is no more effective heat dissipation method for high temperature areas (such as centrifugal fans) 2. There is no targeted Centrifugal fans are designed to dissipate heat.

In the design and production of vehicle emergency power supply, most of them will have the docking of the EC connector. Through the docking of the EC connector, the current of the power battery is loaded from the igniter to the car battery. All almost all on-board emergency power supplies require the installation of the commonly used EC pair plugs. The most common layout is to install the EC male female socket on the product body, and then match the ignition clip with the female male socket. At present, the common fixing method of the EC male end socket on the vehicle emergency power supply products is to leave a square clip on the upper shell and the lower shell. When assembling, the upper and lower shells are closed, and the EC male end socket is fixed in the middle for positioning. The disadvantages of the currently commonly used structure are: 1. It can only be installed at the same time when the upper shell and the lower shell are assembled, which is difficult to install. It needs to deal with the connecting wires drawn from the plug at the same time, and it is impossible to see whether the internal wiring is arranged during the installation process. it is good. 2. There may be looseness after installation, and the experience of plugging and unplugging of the male plug is poor, and the matching accuracy of the upper shell, the lower shell and the EC male socket is required to be high.
