Due to technological progress and economic prosperity, means of transportation such as fuel vehicles have become very popular. However, in recent years, many countries have noticed the depletion of earth's resources and environmental protection issues, so the industry is actively developing various alternatives, and electric vehicles are one of them.

Because the power source of the electric vehicle is electric power, it is necessary to regularly supplement the required power from the outside. It is known that most of the charging devices on the electric vehicle are designed with a combination of plugs and sockets, that is, male and female connectors. This kind of design has at least the following disadvantages: when the electric vehicle is parked in a place with insufficient light (or at night with poor vision), due to the need for mechanism alignment, it is quite difficult to connect the charging connector, which often costs a lot of money. Less time and energy. In addition, if the charging cable is pulled by a strong external force during the charging of the vehicle, it is easy to cause the vehicle to overturn, endangering safety. Furthermore, there are many types of connectors, such as two-pin connectors and three-pin connectors, and pin shapes such as round pins and square pins, etc., which often cause compatibility problems. Therefore, the structural design of the current electric vehicle charging device is not very ideal.

The purpose of this utility model is achieved in that the charging device is applied to the electric vehicle system and includes a socket mechanism, a plug mechanism, and an elastic member, wherein the socket mechanism is installed on the electric vehicle, and the plug is installed on the power supply facility.

The socket mechanism includes a socket frame, a first magnetic part, and a socket terminal. The socket frame is formed with a groove, the first magnetic part is embedded in the socket frame, and the socket terminal is embedded in the socket frame and exposed to the groove of the socket frame.

The plug mechanism includes a plug frame, a second magnetic part, and a plug terminal. The plug frame is formed with a head, the second magnetic part is embedded in the plug frame and is attracted to the first magnetic part, and the plug terminal is embedded in the plug frame and exposed to the head of the plug frame.

The above-mentioned plug mechanism is selectively combined with the socket mechanism according to charging or not. When it is desired to charge, the plug terminal is contacted with the socket terminal, at this time, the head is accommodated in the groove, and the elastic member is interposed between the head and the groove wall of the groove.

The wall of the above-mentioned groove may further include a snap-in groove for more stably receiving the elastic member. The elastic member can be an O-ring, which can be always embedded in the outer circumference of the head, or often embedded in the above-mentioned engaging groove.

The first magnetic part and the second magnetic part can be respectively exposed on the groove and the head, and arranged flush with the socket terminal and the plug terminal respectively. A locating pin protrudes axially from the head, and a locating hole can be recessed at the bottom of the groove to accommodate the locating pin, thereby achieving correct positioning, especially when the plug and socket are circular.

The socket mechanism can be installed in the area below the seat cushion of the electric vehicle and above the center of the rear wheel, can also be installed in the area below the headlight of the electric vehicle and above the center of the front wheel, and can also be installed between the headlight and the hand of the electric vehicle. Put the area in between.

The utility model has the advantage that, by means of the above-mentioned charging device, not only the connection between the plug/socket is fast and convenient, but also the problem of difficult mechanism connection due to poor vision of the environment can be solved. Moreover, the elastic member can provide a further fixing force when the plug/socket is combined, but it does not hinder the safety purpose that the plug and the socket will be separated from each other when the electric connecting wire is pulled by a strong external force. Furthermore, this kind of mechanism design does not need to worry about the consistency of the pin specifications of the plug, and also improves the compatibility of the pins.
