Description

Technical Field

[0001] The present invention relates to the technical field related to charging protection structures, and in particular to a charging protection structure for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as a power source, integrate advanced technologies in vehicle power control and drive, and form advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. With the gradual popularization of new energy vehicles, charging piles have also emerged. As a supporting component of electric vehicles, they are distributed and installed in garages such as major shopping malls, communities, and apartments. With the birth of charging piles, there will be more and more problems in charging, such as anti-collision, waterproof, and anti-tearing. During the charging process, the charging gun needs to be inserted into the charging slot of the new energy vehicle. Many users may charge overnight or during the charging process, they may experience five or six hours. The time interval is too long. After the electric car is fully charged, they may often forget to unplug the charging gun, thereby starting the electric car, thereby breaking the wire of the charging gun, and even pulling down the charging pile, causing the charging pile to catch fire, causing huge losses. There are also many related patents in the existing patent technology that address this issue. For example, a new energy vehicle charging protection device with patent application number CN202311681522.8 only separates the charging gun from the vehicle, and the charging gun shell is mostly a plastic shell. The falling of the charging gun due to the separation from the vehicle may cause the charging gun shell to crack and the charging gun muzzle to be damaged, thereby affecting the normal use of the charging gun. At the same time, the charging gun falling to the ground is not convenient for the next use, and it may not be able to protect the charging gun and its charging gun muzzle well.

[0026] Method of use of the present invention:

[0027] In the initial state:

[0028] The charging gun 19 is inserted on the pile body 13, the sleeve 36 is at the end farthest from the electromagnet 37, the protective claw 31 is lifted by the abutment plate 46 on the sleeve 36, the No. 1 torsion spring 32 is in a tightened state, the spring 28 is in contact with the button 27, the No. 2 torsion spring 40 is in a normal state, the reel 39 is not clamped by the clamping plate 45, the slider 50 is at the top of the fixed block 47, and the spring 49 is in a normal state.

[0029] When the user needs to use the present invention, the user needs to hold the charging gun 19, manually press the spring 28, thereby pressing the button 27, loosening the buckle on the charging port side of the charging gun 19, and pulling out the charging gun 19. As the charging gun 19 moves, the wire 22 and the traction rope 38 will be pulled out, and as the wire 22 is pulled out, the electric slider 53 will slide toward the fixed rod 51 under the traction of the wire 22 until the charging gun 19 is docked with the charging port on the tram. It will be sensed by the sensor on the charging port side of the charging gun 19, and then fed back to the control panel 12, and then the user can start charging. When the charging gun 19 starts to transmit power to the tram, the electric slider 53 will slide toward the fixed rod 51 under the traction of the wire 22. The motor 42 will be started under the action of the control panel 12. After the motor 42 is started, its motor shaft will drive the screw 44 to rotate, thereby driving the clamping plate 45 to move through the rotation of the screw 44, thereby clamping the reel 39. At the same time, the air pump 20 will also be started under the action of the control panel 12. After the air pump 20 is started, it will supply air to the airbag 33 through the air pipe 26, so that the airbag 33 will expand. When the use is over, the user inserts the charging gun 19 back to the pile body 13, and the control panel 12 drives the air pump 20 to start again to discharge the gas in the airbag 33 through the air pipe 26. When the user forgets to unplug the charging gun 19 after completing the charging, the vehicle After the vehicle drives away, the distance between the charging gun 19 and the pile body 13 will change, and because the reel 39 is locked, the length of the traction rope 38 will not change, and because the charging gun 19 is pulled, the traction rope 38 will be tightened, so that the slider 50 will be pulled toward the pressure sensor 48 under the traction of the traction rope 38, and the spring 49 is compressed and deformed. As the slider 50 moves, the elastic band 29 will also be pulled by the slider 50, so that under the traction of the elastic band 29, the spring 28 is driven to press the button 27, thereby releasing the buckle of the charging gun 19 toward the charging port, so that the charging gun 19 is no longer locked with the charging port of the tram, and at the same time As the slider 50 slides downward, the pressure sensor 48 detects the change in pressure, thereby transmitting a signal to the control panel 12. After receiving the signal transmitted by the pressure sensor 48, the control panel 12 will drive the electromagnet 37 to change the magnetic pole, so that the electromagnet 37 attracts the sleeve 36, so that the protective claw 31 is no longer resisted by the abutment 46, and the No. 1 torsion spring 32 is no longer restricted by the abutment 46, the protective claw 31 will rotate toward the charging port of the charging gun 19, and the airbag 33 and the abutment 46 will contact the charging port of the tram, thereby ejecting the charging gun 19 to one side (short distance), thereby completing the separation of the charging gun 19 from the tram,At the same time, as the protective claw 31 continues to rotate, the airbag 33 will wrap the charging gun 19 and completely wrap the charging head of the charging gun 19. The larger side of the charging head of the charging gun 19 will fall to the ground first, and under the protection and buffering of the protective claw 31 and the airbag 33, the charging gun 19 itself will not be damaged, thereby avoiding the damage of the charging gun 19 falling to the ground. At the same time, the motor 42 is also started under the action of the control panel 12, driving the screw 44 to flip, so that the clamping plate 45 no longer clamps the reel 39, and the slider 50 begins to reset under the action of the spring 49. At the same time, the control panel 12 will drive the electric slider 53 to start. After starting, the electric slider 53 will slide and reset in the direction away from the fixing rod 51, thereby opening the wire 22 in the protective The length of the protective shell 14 is determined by the electric wire 22, so that the charging gun 19 is pulled by the electric wire 22. Finally, the charging gun 19 will return to the protective shell 14 under the traction of the electric wire 22, and the airbag 33 will help the charging port of the charging gun 19 to prevent dust, without affecting the normal use of the charging gun 19. When the user needs to use the charging gun 19, the control panel 12 can be used to drive the electromagnet 37 to change the magnetic pole, so that the sliding sleeve 36 slides toward the protective ring 30, driving the protective claw 31 to reset. At the same time, the air pump 20 will also be started under the action of the control panel 12, and the gas in the airbag 33 will be discharged through the air pipe 26, which is convenient for the next use. At this time, the user can insert the charging gun 19 into the pile body 13 or insert the charging gun 19 into the charging port on the tram. ,
