As shown in fig. 1, a guiding structure is provided according to a first embodiment of the present invention. This guide structure sets up on charging the door to through guide structure guide charging the door motion to dodging the charging position of charging the mouth or covering the position that covers of charging the mouth. The guide structure includes a body portion 10, a first guide groove 20, and a positioning portion 30, and the body portion 10 is disposed on the charging door. The first guide groove 20 is disposed on the main body 10, the positioning portion 30 is spaced apart from the first guide groove 20, and the positioning portion 30 is adapted to a positioning structure on an installation base, so as to position the charging door by the positioning portion 30. The first guide groove 20 has a guide start end and a guide end which are oppositely arranged, and the positioning portion 30 is located at the guide end. Specifically, the installation basis in this embodiment is the installation basis of charging door, and charging door can install on the automobile body, and location structure can movably set up on the automobile body to fix a position charging door through location structure and the cooperation of location portion 30, thereby restrict charging door's position. Still be provided with the guide post on the installation basis, the guide post sets up with first guide way 20 looks adaptation, and the guide post is fixed to be set up, can be convenient for guide structure's motion through the cooperation of guide post and first guide way 20 to make guide structure can accomplish predetermined action.

Adopt the guide structure that this embodiment provided, through be provided with first guide way 20 on this somatic part 10, can be convenient for lead the motion of door that charges through first guide way 20 to make the door that charges move to the position of charging or cover the position, thereby be convenient for guide smoothly the motion of door that charges, improved the smoothness nature of motion. Specifically, when the guide start end of the first guide groove 20 is in the guide state, the charging door is in the charging position. When the direction end of first guide way 20 is in the guide state, the door that charges is in and covers the position, afterwards, the location portion 30 that is located the direction end will be fixed a position with the location structure of installation basis to the motion of restriction door that charges, thereby avoided the easy condition that takes place to become flexible of door that charges in the operation, thereby can carry out effectual protection to the mouth that charges, with the life who improves the mouth that charges, reduce the maintenance cost to the mouth that charges. Therefore, through the guide structure that this embodiment provided, can solve the electric motor car among the prior art the charging door of electric motor car and easily take place not hard up technical problem.

In this embodiment, the first guide groove 20 is a spiral groove structure, through which the charging gate can be conveniently driven to perform a spiral linear motion. With such a structural arrangement, it is possible to easily rotate and open the charging door so as to move the charging door to the charging position or the covering position. In this embodiment, can set up a plurality of first guide ways 20, a plurality of first guide ways 20 interval sets up, it is corresponding, there are a plurality of guide posts, a plurality of guide posts set up with a plurality of first guide ways 20 one-to-one, each guide post is used for cooperating corresponding first guide ways 20, cooperation structure through a plurality of guide posts and a plurality of guide ways, can improve the stability of motion, the motion stability of door is charged in order to better improvement, move to the position of charging or dodge the position in order to guarantee to charge the door.

Specifically, the positioning portion 30 may be a positioning hole, and correspondingly, the positioning structure of the charging door is a positioning column, and the positioning column is used to be inserted into the positioning hole. Specifically, the setting of reference column telescopic, when charging the door and be in and hide the position, the reference column is inserted and is established in the locating hole to carry on spacingly to charging the door.
