Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle charging piles, and in particular to a new energy vehicle charging pile with an anti-drag structure. Background Art

[0002] With the progress of society, there are more and more new energy vehicles. During the use of new energy vehicles, charging piles are needed for charging. Charging piles are a kind of equipment that is directly connected to the AC power grid at the input end and equipped with a charging plug at the output end. It is used to charge electric vehicles. Generally, two charging methods are provided: conventional charging and fast charging. People can use specific charging cards or even scan codes with their mobile phones and use them on the human-computer interaction interface provided by the charging piles to perform corresponding charging methods.

[0003] For example, the Chinese patent with announcement number CN219029156U discloses a charging pile with an anti-drag structure for new energy vehicles, including a riser, a detection unit and a pop-up unit.

The detection unit is arranged inside the riser, the lower end of the detection unit is fixedly connected to the upper surface of the fixing plate, and the detection unit is arranged in coordination with the cable.

[0004] However, the above scheme has the following shortcomings: in the above patent, the sliding bar is driven to move by the electromagnetic push-pull rod, and the large spring applies a rightward force to the pop-up seat. The inclined inner wall of the positioning hole at the left end of the pop-up seat drives the limit bar to move, and the large spring moves the charging gun to the left under the support of the pop-up seat, thereby realizing the pop-up of the charging gun. However, the above patent lacks a structure to protect the charging gun after it is popped out. Since the charging gun is automatically popped out after the new energy vehicle is driving, and the charging port of the new energy vehicle is at a certain distance from the ground, when the charging gun automatically pops out and falls to the ground, the charging port of the charging gun may be damaged, resulting in the charging port of the charging gun being unable to be inserted into the charging port of the new energy vehicle when the charging gun is used for charging next time, or normal charging cannot be performed after insertion.

The air guide cavity 34 is opened in the charging gun 3. After the gas enters the air guide cavity 34, the protective mechanism extends outward to protect the plug 29 to prevent the plug 29 from being damaged after falling to the ground, resulting in the situation that it cannot be used. The end of the charging gun 3 away from the plug 29 is respectively fixedly connected with a cable 4 and an air guide tube 5, and the air guide tube 5 is connected with the air guide cavity 34. The cable 4 is used to supply power to the plug 29; like Figure 2 , Figure 7 As shown, the cable 4 and the air guide tube 5 are connected to the deflation mechanism after passing through the limiting ring 7 at one end away from the charging gun 3. The limiting ring 7 is fixedly connected to the lower side of the charging pile body 1. The deflation mechanism is fixedly connected to the cross-shaped slider 19. The limiting ring 7 is used to limit and guide the cable 4 so that after the cable 4 is pulled, the cross-shaped slider 19 can move downward. The cross-shaped slider 19 is slidably connected to the sliding cavity 22, and the inflated protective mechanism is exhausted through the deflation mechanism. A telescopic slider is fixedly connected inside the cross-shaped slider 19. When the cross-shaped slider 19 moves downward, the telescopic tube 18 will be pulled. When the cross-shaped slider 19 moves upward, the telescopic tube 18 will shrink and return to its initial state. A clamping hole 39 is provided in one side of the cross-shaped slider 19. A push switch 8 is fixedly connected in the clamping hole 39. A clamping mechanism is provided in the sliding cavity 22. When the cable 4 is dragged, the cross-shaped slider 19 moves downward along the sliding cavity 22, so that the clamping mechanism is clamped in the clamping hole 39, and the push switch 8 is pressed at the same time. like Figure 1 As shown, the end of the telescopic tube 18 away from the cross-shaped slider 19 extends into the installation cavity 12 and is connected to the output end of the solenoid valve 11.

[0018] Embodiment 2: On the basis of Example 1, in order to prevent the annular airbag 33 from extending out after a certain distance, the protective mechanism includes an annular airbag 33, which is fixedly installed in the annular cavity 32, and the annular cavity 32 is opened in one end of the charging gun 3. The annular airbag 33 is fixedly connected to an end close to the plug 29 with an annular baffle 36, and the annular baffle 36 is arranged in the annular cavity 32. A magnetic ring 38 is arranged on the inner side of the annular baffle 36, and the magnetic ring 38 is fixedly installed in the charging gun 3. The gas enters the annular airbag 33 through the air guide cavity 34. After being inflated, the annular airbag 33 will expand and extend outward, and drive the annular baffle 36 to move synchronously. At this time, under the push of the annular airbag 33 and the annular baffle 36, the plug 29 will be pulled out of the charging port of the car, and the annular airbag 33 that is quickly inflated and extended will also wrap and protect the plug 29 to prevent the plug 29 from being damaged after falling to the ground; like Figure 4 , Figure 5 As shown, a traction rope 37 is provided in the annular cavity 32, one end of the traction rope 37 is fixedly connected to the annular baffle 36, and the other end extends into the connecting cavity 35 and is connected to the travel switch 9. The connecting cavity 35 is opened in the charging gun 3, and the connecting cavity 35 is connected to the annular cavity 32. The travel switch 9 is fixedly installed in the connecting cavity 35. The specific model of the travel switch 9 is the WK-01-TZ12 micro switch produced by Yueqing Yayu Electronics Co., Ltd. When the annular baffle 36 moves outward, the traction rope 37 will be driven to move synchronously. When the annular airbag 33 completely wraps the plug 29, the annular baffle 36 will straighten the traction rope 37. When the annular baffle 36 moves again, the traction rope 37 will open the travel switch 9. At this time, the solenoid valve 11 will be closed, and the gas in the gas tank 10 will no longer enter the annular airbag 33, so as to prevent the annular airbag 33 from exploding due to excessive inflation. The limiting mechanism includes two T-shaped limiting rods 28 located at the upper and lower sides of the plug 29, the T-shaped limiting rod 28 is slidably connected in the sliding cavity 20, the sliding cavity 20 is opened in the plug 29, a first spring 15 is fixedly connected in the sliding cavity 20, the other end of the first spring 15 is fixedly connected to the T-shaped limiting rod 28, the opposite ends of the two T-shaped limiting rods 28 are fixedly connected with a pull rope 30, the pull rope 30 is fixedly connected to the output end of the electric telescopic rod 31 away from the end of the T-shaped limiting rod 28, the electric telescopic rod 31 is fixedly installed in the charging gun 3, the electric telescopic rod 31 can be selected according to the actual use situation. The clamping end of the T-shaped limiting rod 28 is arranged in an inclined shape, and the electric telescopic rod 31 is started by pressing the button 14. The electric telescopic rod 31 starts to drive the two pull ropes 30 connected to its output end to start moving, and the movement of the pull rope 30 drives the T-shaped limiting rod 28 to move into the sliding cavity 20; like Figure 7As shown, the deflation mechanism includes a connecting block 6, one end of the connecting block 6 is fixedly connected to the cable 4 and the air guide tube 5, and the other end is fixedly connected to the cross-shaped slider 19. In actual use, the wire in the charging pile body 1 is connected to the cable 4 at one end of the connecting block 6, and the wire should be reserved with sufficient length so that the cross-shaped slider 19 can move downward after the cable 4 is dragged. A guide cavity 21 is provided in the connecting block 6, one end of the guide cavity 21 is connected to the air guide tube 5, and the other end is connected to the telescopic tube 18. A valve 16 is fixedly connected to the lower end of the connecting block 6, and the upper end of the valve 16 is connected to the guide cavity 21. The annular airbag 33 can be deflated by opening the valve 16. A reset spring 23 is fixedly connected to the lower end of the cross-shaped slider 19, and the other end of the reset spring 23 is fixedly connected to the sliding cavity 22. A box door 17 is movably installed on one side of the charging pile body 1, and the gas tank 10 can be replaced by opening the box door 17. like Figure 2 , Figure 3 As shown, the clamping mechanism includes a T-shaped clamping rod 27, which is slidably connected to the storage cavity 25. The storage cavity 25 is opened in the charging pile body 1. A support spring 26 is fixedly connected to the storage cavity 25. The other end of the support spring 26 is fixedly connected to the T-shaped clamping rod 27. An electromagnet 24 is arranged on the inner side of the support spring 26. The model of the electromagnet 24 can be selected according to the corresponding size and model when in use. The electromagnet 24 is fixedly installed in the storage cavity 25. The T-shaped clamping rod The clamping end 27 is arranged in an arc shape. Since the two sides of the lower end of the cross-shaped slider 19 are arranged in an arc shape, and the clamping end of the T-shaped clamping rod 27 is arranged in an arc shape, during the downward movement of the cross-shaped slider 19, the T-shaped clamping rod 27 will be squeezed to move into the storage cavity 25. At this time, the support spring 26 is compressed. When the T-shaped clamping rod 27 moves to the position of the clamping hole 39, under the elastic force of the support spring 26, the T-shaped clamping rod 27 will be clamped into the clamping hole 39.

[0019] Working principle: during use, when the car needs to be charged, the button 14 is pressed to start the electric telescopic rod 31. The electric telescopic rod 31 starts to drive the two pull ropes 30 connected to its output end to start moving. The movement of the pull rope 30 drives the T-shaped limit rod 28 to move into the sliding cavity 20, so that the first spring 15 is compressed. At this time, the charging gun 3 can be pulled out to pull the plug 29 from the socket 2. After the pull-out is completed, the plug 29 can be inserted into the charging port of the car. After releasing the button 14, under the elastic force of the first spring 15, the T-shaped limit rod 28 is snapped into the charging port of the car. At this time, the new energy vehicle can be charged. When the new energy vehicle drives the charging gun 3 to move, the electric The cable 4 will be driven to move. Under the limiting action of the limiting ring 7, the cable 4 is dragged to make the cross-shaped slider 19 move downward. Since the two sides of the lower end of the cross-shaped slider 19 are arranged in an arc shape, and the clamping end of the T-shaped clamping rod 27 is arranged in an arc shape, during the downward movement of the cross-shaped slider 19, the T-shaped clamping rod 27 will be squeezed to move into the storage cavity 25. At this time, the support spring 26 is compressed. When the T-shaped clamping rod 27 moves to the position of the clamping hole 39, under the elastic force of the support spring 26, the T-shaped clamping rod 27 will be clamped into the clamping hole 39, and the push switch 8 located in the clamping hole 39 will be pressed. At this time, the electric telescopic rod 31 and the solenoid valve 11 are opened; After the electric telescopic rod 31 is started, the T-shaped limit rod 28 is retracted into the sliding cavity 20. After the solenoid valve 11 is opened, the high-pressure gas in the gas tank 10 enters the telescopic tube 18. The gas entering the telescopic tube 18 enters the air guide tube 5 through the guide cavity 21. Finally, the gas enters the annular airbag 33 through the air guide cavity 34. After being inflated, the annular airbag 33 expands and extends outward, and drives the annular baffle 36 to move synchronously. At this time, under the push of the annular airbag 33 and the annular baffle 36, the plug 29 will be pulled out of the charging port of the car. At the same time, the annular airbag 33 that is quickly inflated and extended will also wrap and protect the plug 29 to prevent the plug 29 from falling to the ground and being damaged. At the same time, when the annular baffle 36 moves outward, it will drive the traction rope 37 to move synchronously. When the annular airbag 33 completely wraps the plug 29, the annular baffle 36 will straighten the traction rope 37. When the annular baffle 36 moves again, the traction rope 37 will open the travel switch 9. At this time, the solenoid valve 11 will be closed, and the gas in the gas tank 10 will no longer enter the annular airbag 33, preventing the annular airbag 33 from exploding due to over-inflation. When the device needs to be reset, the electromagnet 24 is turned on to adsorb the T-shaped clamping rod 27 so that the T-shaped clamping rod 27 is stored in the storage chamber 25. At this time, under the elastic force of the reset spring 23, the cross-shaped slider 19 will rise to the initial position, and the annular airbag 33 can be deflated by opening the valve 16, and the annular airbag 33 and the annular baffle 36 can be re-stored in the annular chamber 32. The magnetic ring 38 will adsorb the annular baffle 36 so that the annular baffle 36 is limited in the annular chamber 32, and the plug 29 can be reinserted into the socket 2.
