Description

Technical Field

[0001] The present invention belongs to the technical field of charging devices, and in particular relates to a vehicle-free plate charging connection device and a charging system. Background Art

[0002] Currently, there are three ways to achieve a car-free parking garage. The first is wireless charging, which uses a DC wireless charging mode. The source module must be installed on the new energy vehicle body, and the charging pile is connected to the secondary module. This charging method requires the cooperation of the vehicle manufacturer. The second is a fixed charging robot, which uses a robotic arm with a national standard gun head or a robot with a non-standard adapter. It uses visual positioning to charge the new energy vehicle in need of charging. The third is comb-tooth handling, in which the conductive connection device is exchanged with the transporter, and it needs to be exchanged at least twice during the handling process.

[0003] At present, the technical problems of charging without loading plates in stereo garages are roughly as follows:

[0004] Currently, fixed charging manipulators use a robotic arm or a built-in non-standard adapter coupled with visual positioning to charge vehicles. Due to the varying locations of charging ports across different vehicle models, the manipulator's transmission accuracy is very high. High-precision visual positioning is used to repeatedly determine the charging port's location and then feed its coordinates to an industrial computer. The computer's algorithm processes this information and drives the manipulator to insert the charging port. Due to the immaturity of visual positioning technology and the high cost of the complete system, market adoption is difficult.

[0005] The conductive connection device that is exchanged with the carrier during comb-tooth transportation first needs to be plugged into the car with one end of the connector placed on the parking plate. After the carrier rises, the car and the connector are transported together. After they are transported into place, the car and the connector are lowered at the same time. The connector can then be docked with the connector fixed in the parking space. This method has high positioning requirements because the connector needs to be exchanged twice. At the same time, reliable docking cannot be guaranteed after the docking is completed. In addition, it adopts end-to-end docking, and docking pressure and electrode end surface protection are also relatively large problems. Summary of the Invention

Its internal structure consists of a gear, a working pawl, a pawl rocker, a non-return pawl, a rack, a handle, and a tire clamping rod. When one end of the tire clamping rod is in contact with the tire, the pawl rocker is pushed, causing the gear to rotate, thereby causing the rack and tire clamping rod to retract.

To unlock the clamp, use your left hand to squeeze the pawl rocker and the fixed handle tightly, so that the back of the working pawl aligns with the top of the non-return pawl.

[0052] A charging system based on a non-car-loading plate charging connection device includes an AGV carrier, and a fixed conductive connector of the non-car-loading plate charging connection device is arranged at a parking space that the AGV carrier can reach.

[0053] Specific working principle:

[0054] When a new energy vehicle is parked on the parking board at the entrance or exit of the garage and needs to be charged, the garage manager will install a mobile conductive connector on the tire (such as Figure 6 ), when installing, insert the mobile conductive connector tire clamp rod into the gap between the tire and the front fender, flatten the reference plate with the ground, and then press the two tire clamp rods against the outer ring of the tire, and then tighten the angle locking knob. At this time, start swinging the ratchet rocker to clamp the tire, and insert the charging gun into the charging port of the vehicle. After the installation is completed, Figure 7 As shown, check again whether the mobile connector and the tire are reliably connected. After confirming that there is no problem, the administrator walks out of the garage, closes the garage door, and the garage automatically transports the vehicle. During the transportation process, the AGV carrier lifts the vehicle and the mobile conductive connector is transported to the transverse carrier with the vehicle (as shown in the figure). Figure 8 ), the horizontal transporter moves the car to the parking space (such as Figure 9 ), the AGV transporter transports the car from the top of the parking space comb (such as Figure 10 ), the mobile conductive connector slowly docks with the fixed conductive connector, and the fixed conductive connector is pushed by the mobile conductive connector and then moves forward. When the car reaches the specified position, the carrier descends and places the car on the parking comb. The fixed conductive connector is driven by the mobile conductive connector and descends. At this time, the whole docking process is completed, and parking and connector docking are completed (such as Figure 11 ), the operation screen outside the garage will show that the parking is completed and the charging is ready, and then the card or code is swiped to charge. The no-car-plate charging connection device can realize the charging problem of AGV transport charging station, passenger car intelligent no-car-plate stereo garage, and bus no-car-plate stereo garage ( Figure 12 ).
