Description

Technical Field

[0001] This patent relates to a full-parking charging device for a fixed-parking garage, belonging to the technical field of charging electric vehicles. Background Art

[0002] According to the national electric vehicle development plan, the market urgently needs a charging pile that is simple in structure, easy to use, can provide preferential services to car owners, and can automatically charge all cars stored in a three-dimensional garage with fixed parking spaces.

[0003] Because it is found that the popular charging piles on the market are either manually operated and cannot meet the automatic charging requirements of the multi-story parking garage; or they are horizontal collision insertion type and can only be used around the multi-story parking garage, and cannot meet the automatic charging needs of all the cars stored in the multi-story parking garage. Summary of the invention

[0004] This patent is a charging pile that can be installed in all parking spaces in a three-dimensional garage with fixed parking spaces. Its working process is:

[0005] (1) After the owner has parked the car on the loading platform, he / she should insert the charging plug with wire that comes with the car into the fixed charging socket on the loading platform side beam, or insert the charging plug with wire on the loading platform side beam into the fixed charging socket of the parking car. When the green light of the charging device is on, it means that the parking car is well connected with the charging device on the side beam, and the owner can leave without worry.

[0006] (2) The vehicle-mounted vehicle panel is controlled to move horizontally or upward to the set parking and charging position and stops in preparation for charging.

[0007] (3) The charging convex head is controlled to rise vertically and contact closely with the concave head. The system detects that the charging convex / concave head are in good contact, and the system closes the switch to start charging. The system detects that the battery is fully charged, and the system automatically opens the switch to stop charging. At this time, the vehicle is parked and charging is completed. If necessary, the power can be cut off in advance and the switch can be opened to stop charging.

[0008] (4) The male charging head is controlled to descend vertically into position, and the male / female head is completely detached. If necessary, the vehicle plate is controlled to detach from the charging parking space and move horizontally or descend to the vehicle pick-up area for the owner to pick up the vehicle.

[0009] This patent mainly consists of the following parts:

[0010] (1) A charging connector device (including a charging socket device or a charging plug device with a wire) fixedly connected to the side beam of the vehicle loading plate.

[0011] (2) Qualified connection between the charging connector device (including the charging socket device or the charging plug device with wire) and several sockets and wires.

[0012] (3) A crossbeam fixedly connected to the corrugated plate and vertical ribs of the vehicle-carrying plate, an upper plate properly fixedly connected to the crossbeam, and several recessed heads properly installed on the upper plate.

[0013] (4) Several convex contacts and small springs are properly assembled on the upper guide plate, and a large spring is installed between the concave platform of the upper guide plate and the concave platform of the lower guide plate. The grooves on the same side of the upper guide plate and the lower guide plate form a guiding relationship with the vertical guide plate. The bolts of the long fasteners are properly screwed into the screw holes of the cylinder head of the lifting device, and the pin holes are drilled and then the cotter pins are properly assembled.

[0014] (5) The lifting device and the base are installed properly. There are two types of bases: ① a base installed on the frame, and ② a base installed on the ground.

[0015] (6) The lifting device is one of the following: air cylinder, oil cylinder, or electric cylinder. The technical solution and beneficial effects of the technical problem to be solved by this patent are as follows:

[0016] (1) Technical problems to be solved by this patent:

[0017] ① Manual operation cannot meet the requirements of automatic charging; ② The horizontal collision insertion type can only be used around the stereo garage, and cannot meet the need for automatic charging of all the cars stored in the stereo garage; ③ The horizontal collision insertion has a large deviation and is very easy to damage the charging equipment.

[0018] (2) The technical solution to be adopted by this patent is:

[0019] ① The main structure of this patent is composed of a fixed part + a moving part; ② The key points of the moving part structure are: adopting a technical solution of one-stage lifting transmission + two-stage elastic buffer + cone surface compensation error.

[0020] (3) The beneficial effects of this patent are:

[0021] ① All cars in the multi-storey garage can be automatically charged; ② When the cars are parked and charged at night, they can enjoy the grain price electricity encouraged by the state, which not only solves the environmental protection problem that the country urgently needs to solve, but also solves the problem of digesting the surplus electricity in the power grid, and allows car owners to enjoy the preferential policy of the state's grain price electricity supply.
