Description

Automobile charging port cover body mechanism Technical field

The invention relates to a lock body mechanism.

Background technique

With the intensification of the energy crisis and the deterioration of the environment, pure electric vehicles or hybrid vehicles are getting more and more people's attention, which makes the pure electric vehicle or hybrid vehicle gradually become a development trend. It is an important structural unit of pure electric vehicles or hybrid vehicles. The charging cover of the electric vehicle is generally installed with a charging cover plate of the same color as the body or with a unique shape, and can be smoothly opened when charging, and can be closed and locked after the charging is completed to prevent the requirement of self-opening during the running of the vehicle. Therefore, it is generally required to install a separate unlocking/locking mechanism to lock the charging port cover. When charging, an action required by an unlocking mechanism is unlocked. At present, the unlocking/locking mechanism of the charging cap of the general electric vehicle basically follows the refueling cap unlocking/locking mechanism of the conventional energy vehicle, and the mechanism is generally driven by the driver in consideration of the anti-theft and safety functions of the conventional refueling cap. Unlocked in the cab, the gas station staff opens the flap outside the vehicle for refueling. When the electric vehicle is charged, the driver is generally required to unlock and open the charging port cover at the same time. Obviously, this mechanism is too cumbersome and needs to be improved.

Summary of the invention

The invention provides a car charging port cover lock mechanism capable of simultaneously unlocking and opening a charging port cover.

The technical solution provided by the invention is:

The utility model relates to a car charging port cover lock body mechanism, which comprises a lock body A and a lock body B. The lock body A is connected with the pull rod A, the lock body B is connected with the pull rod B, the pull rod A and the pull rod B are connected to the gear through the rack, and the rack connecting the fixed rod The fixing rod is fixed by the tension spring, and the lock body A and the lock body B are all provided with a duck tongue lock, and the duck tongue locks and presses into the panel hinge mouth.

The charging port cover lock body device of the invention is designed as a connecting rod + gear mechanism, and the initial position of the lock body is fixed by the spring pulling force, the unlocking button is pressed, the locking is pulled, the panel rises directly, and when the use is completed, the hand presses the panel downwards, when pressed down The lock body is opened, pressed down to a certain position, and the lock is snapped into the hinge mouth of the lower part of the panel, so that the panel cover is locked, which is very convenient and safe.

detailed description

The invention will be further described in detail below with reference to the accompanying drawings.

As shown in Fig. 1, a car charging port cover body mechanism comprises a lock body A1, a lock body B2, a lock body A1 is connected to the pull rod A3, a lock body B2 is connected to the pull rod B4, and the pull rod A3 and the pull rod B4 are connected to the gear 6 through the rack 5 The upper and lower racks are connected with a fixing rod 7, and the upper and lower fixing rods 7 are respectively fixed by the upper and lower tension springs 8. The lock body A1 and the lock body B2 are respectively provided with a duck tongue lock 9 and the duck tongue is locked. 9 press down into the panel hinge opening 10. As shown in Fig. 1, the charging port cover is in an initial state, and the duck tongue lock 9 is stuck in the panel hinge port 10, and the duck tongue lock 9 is tensioned and fixed by the tension spring 8 and the fixing rod 7, and the hinge is locked.

When closed, the panel is pressed downwards. When the hinge is pressed down, the tongue lock 9 is pushed backwards, pulling the upper and lower links, and the elastic device is forced to open. When the pressure is pressed into place, the front section of the duck tongue is locked. Interference, the elastic device begins to return to the initial state, and the duck tongue is inserted into the hinge mouth (as shown in Figure 3), and the panel is locked.
