Description

Technical Field

[0001] This utility model relates to the field of new energy charging equipment technology, and in particular to an integrated new energy charging and discharging gun. Background Technology

[0002] With the continuous development of the new energy vehicle industry, the growth rate and number of cars in China are constantly expanding, leading to increasingly severe environmental pollution problems, while my country's fossil energy reserves are becoming increasingly strained. Currently, pollution-free electricity is gradually replacing fossil fuels, and new energy vehicles have become an important development direction for the automotive industry.

[0003] Nowadays, more and more new energy vehicles have the function of external discharge, which can convert the DC power inside the vehicle into AC power and supply it to a dedicated discharge outlet for use by external electrical devices. However, traditional new energy charging guns can only transmit power in one direction to achieve the charging function, which is relatively simple. When users need to use the discharge function outdoors, they need to purchase a dedicated discharge gun, which is cumbersome to use and requires more storage space. Common electric vehicle charging methods usually rely on dedicated charging stations or wall-mounted chargers, which limits users' ability to charge at home or other non-dedicated charging locations. At the same time, the existing household power sockets are mainly designed to meet the power needs of traditional electrical appliances and do not directly support the high power output required for electric vehicle charging. Therefore, users who want to charge electric vehicles with household power often need to use a conversion adapter or purchase a dedicated mobile charging device, which not only increases the user's investment costs but also poses safety hazards such as insufficient overload protection and aging wires. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated new energy charging and discharging gun. The control box integrates a PCBA and a household power strip unit, which can not only quickly charge new energy electric vehicles, but also use the discharge of new energy electric vehicles to power household appliances. This effectively solves the technical problems of existing new energy electric vehicle charging and discharging equipment being costly, space-consuming, and cumbersome to operate, and unable to directly utilize household power strip units for charging and discharging.

The cable clamping plate is fixedly connected to the cable slot, thereby improving the installation stability between the conductive cable and the upper housing and limiting the routing direction of the conductive cable.

[0014] In some possible implementations, the inner surfaces of the cable slot and the cable clamp are provided with anti-slip textures to improve the stability when the cable slot and the cable clamp are in contact with the conductive cable, and to prevent the conductive cable from moving around in the wire hole.

[0015] In some possible implementations, the gun body includes a hollow gun shell connected to the gun head, a terminal assembly is provided inside the gun head, a locking mechanism and a micro switch are provided inside the gun shell, the locking mechanism and the micro switch are located above the terminal assembly, the rear end of the terminal assembly is electrically connected to a conductive cable, the rear end of the conductive cable extends out of the rear port of the gun shell and is connected to a charge and discharge control box, and a waterproof tail cap is fitted between the conductive cable and the gun shell.
