Guide post type electric shock prevention safety charging socket for electric vehicle

Abstract

A guide post type electric shock prevention safety charging socket for an electric vehicle comprises a charging socket shell and an isolator, an inner concave cavity is machined in the charging socketshell, and a pole is arranged in the inner concave cavity; the isolator is arranged on the surface of the inner concave cavity, a socket is formed in the surface of the isolator, and the socket corresponds to the position of the pole; the isolator is integrally connected with a guide post I and a guide post II; the guide post II is elastically connected with the charging socket shell; the charging socket shell is provided with a through hole I, and the bottom of the through hole I is connected with an end socket; and one end of the guide post I stretches into the through hole I, a guide column is arranged in the guide post I in a sliding mode, and the guide column is in guide connection with the through hole I through a guide structure. Compared with the prior art, the charging socket iscompact in structure and convenient to operate with one hand, can effectively prevent children from inserting metal foreign matter such as coins into the charger interface to cause short circuit of the battery of the electric vehicle when playing, can effectively improve the safety, and has wide applicability.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a guide post-type anti-electric shock safe charging socket for electric vehicles. Background technique [0002] Electric vehicles are currently a new type of green travel vehicle. In order to increase its power, most of the batteries use 48 volts to 72 volts and above, which has exceeded the human body's DC safety voltage of 36 volts; during the use of electric vehicles, there must be However, there are no effective protective measures for the interface and connector of the existing charger. It often happens that children insert metal foreign objects such as coins into the charger interface when they are playing, causing a short circuit of the battery of the electric vehicle and causing an accident. Research on the charging interface, and design one that can prevent electric shock without affecting the convenience of charging. [0003] Most areas in our country...

Problems solved by technology

People's research on the safety of electric vehicles mainly focuses on natural self-explosion, charging management systems, etc., but they do not pay enough attention to the safety hazards at the charging port; Some protective measures have been added, but the effect is not ideal, but it makes the charging process more complicated and affects the user experience; for example, it is more common to install a spring cover on the traditional charging socket, which has a certain protective effect, but this It also makes the charging process inconvenient and requires more steps to complete the operation. Under certain circumstances, it will arouse children's curiosity and cause more accidents; another common method is to replace the internal safety circuit and add some For miniature electronic components, this method is feasible, but the workload of disassembly and debugging is large, and there is no universal adaptability
