Automatic adjusting and fixing device for charging port of new energy automobile

Abstract

The invention discloses an automatic adjusting and fixing device for a charging port of a new energy automobile. The automatic adjusting and fixing device includes a shell, and a rectangular groove isformed in the center of the interior of the shell. A fixing cylinder is arranged in the groove, a spiral ring is arranged in the fixing cylinder in a surrounding mode, a plurality of contact rods arearranged in the spiral ring in a surrounding mode, a fixing plate is arranged at one end of the fixing cylinder, a sliding groove is formed in the side wall of the fixing plate, and a ratchet wheel is arranged at the end, close to the fixing plate, of the spiral ring in a surrounding mode. When the spiral ring rotates, the spiral ring contracts towards the center of the interior; the contact rodis driven to extrude towards the center, the inserting rod of the charging head can be attached to the contact rod, electric power is transmitted to the surface of the contact rod through the inserting rod of the charging head and then transmitted to a cable at one end of the fixing plate through the contact rod, and the automatic adjusting and fixing device has the advantages of being capable ofautomatically fixing the charging plug and being suitable for charging heads of different diameters.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to an automatic adjustment and fixing device for a charging port of a new energy vehicle. Background technique [0002] Affected by the rapid development of new energy electric vehicles, supporting facilities such as charging piles and charging stations will also usher in rapid development. The construction of charging facilities is one of the key links in the demonstration and promotion of new energy vehicles. Benefiting from the rapid growth of new energy vehicle applications, my country The new energy vehicle charging facility industry will face a huge space for development, and the current charging ports of new energy vehicles are usually set inwards. [0003] The traditional charging port transmits electric energy to the battery inside the car by contacting the charging plug. However, the traditional contact method is too simple. After a long period of use, it is easy to wea...
