Automobile charging pile locking reduction gearbox and automobile charging port cover actuator driven by wear-resistant silent gear

With the continuous support of policies and the recovery of sales of new energy vehicles, new energy vehicles usher in new development opportunities. However, charging facilities are still the main weakness of the new energy vehicle industry chain. The insufficient number, uneven distribution, incomplete interconnection and other practical problems of charging piles lead to insufficient charging convenience, which affects the charging experience and sense of acquisition of new energy vehicle users, and also restricts the rapid and healthy development of the new energy vehicle industry to a certain extent.

Charging facilities are connected to the construction of automobiles, cities and power grids. At present, the charging pile with "extensive network" and "low connectivity" has a low utilization rate. The main problem is the unreasonable planning and layout. The construction of charging facilities should be combined with the construction of smart cities. However, the deep problem is that the current voltage of charging piles is generally higher than that of domestic power, which greatly increases the risk of electric shock for consumers. Therefore, the electric shock prevention measures provided by the charging pile are indispensable. The potential hazards of the charging gun are also easily overlooked.

This is mainly because the voltage of charging piles is very high, some of which reach about 750 volts, several times higher than the voltage of ordinary household electricity. Even if the user does not directly contact the charged contact of the charging gun, but the contact distance is too close, there may be a fatal risk of electric shock. As required, in order to prevent the user from pulling out the gun and getting electric shock during charging, the charging pile needs to set an electronic lock inside to monitor the charging state.

Making the charging pile easy to use and durable is a problem that many new energy vehicle charging pile equipment manufacturers urgently need to solve. According to the application requirements, the professional micro reduction gearbox manufacturer will adopt micro transmission technology to optimize the locking gearbox structure of the charging gun electronic lock of the charging pile. Through the analysis and design of the charging pile gear box scheme, adjust the gear module and torque of the charging pile locking gear box to improve the overall motion accuracy, reliability, environmental adaptability and equivalent energy of the charging pile, and improve its service life; The reduction gear box and screw are used to make the charging plug stay stably in the buckle of the socket or fixed base when the charging pile moves forward, so as to realize the locking function. After charging (when moving in reverse direction), the charging plug is separated from the socket or the buckle of the fixed seat to realize the unlocking function, which can realize the charging of the electric vehicle under unattended conditions.
