Description

[0002] With the progress of society, more and more new energy vehicles are used, and the new energy vehicles need to be charged by using charging piles. The charging pile is a device with an input end directly connected with an alternating current power grid and an output end provided with a charging plug, used for charging electric vehicles. The charging pile generally provides two charging modes of conventional charging and fast charging. People can use a specific charging card or even scan a code by using a mobile phone on the man-machine interactive operation interface provided by the charging pile to perform corresponding charging.

[0032] Example 2:

[0033] On the basis of Example 1, in order to prevent the annular airbag 33 from extending further after extending a certain distance, the protective mechanism includes an annular airbag 33, which is fixedly installed in an annular cavity 32. The annular cavity 32 is opened in one end of the charging gun 3, and an annular baffle 36 is fixedly connected to the end of the annular airbag 33 near the plug 29. The annular baffle 36 is arranged in the annular cavity 32, and a magnetic ring 38 is provided on the inner side of the annular baffle 36. The magnetic ring 38 is fixedly installed in the charging gun 3. 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. 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.

[0034] 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, thereby preventing the annular airbag 33 from exploding due to over-inflation.

[0035] The limiting mechanism includes two T-shaped limiting rods 28 located on the upper and lower sides of the plug 29. The T-shaped limiting rod 28 is slidably connected to the sliding cavity 20. The sliding cavity 20 is opened in the plug 29. A first spring 15 is fixedly connected to 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 to a pull rope 30. The pull rope 30 is away from one end of the T-shaped limiting rod 28 and is fixedly connected to the output end of the electric telescopic rod 31. The electric telescopic rod 31 is fixedly installed in the charging gun 3. The electric telescopic rod 31 can be selected in the corresponding size and model according to the actual usage. The clamping end of the T-shaped limiting rod 28 is arranged in an inclined shape. Pressing the button 14 starts 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 limiting rod 28 to move into the sliding cavity 20;

[0036] like Figure 7As shown, the deflation mechanism includes a connecting block 6, one end of which is fixedly connected with the cable 4 and the air guide pipe 5, and the other end is fixedly connected with the cross-shaped sliding block 19. In actual use, the wire in the charging pile body 1 is connected with the cable 4 at one end of the connecting block 6, and at the same time, the wire should be reserved with sufficient length, so that after the cable 4 is pulled, the cross-shaped sliding block 19 can move downward. A guide cavity 21 is formed in the connecting block 6, one end of which is in communication with the air guide pipe 5, and the other end is in communication with the telescopic pipe 18. The valve 16 is fixedly connected to the lower end of the connecting block 6, and the upper end of the valve 16 is in communication with the guide cavity 21. By opening the valve 16, the annular air bag 33 can be deflated. The cross-shaped sliding block 19 is fixedly connected with a reset spring 23 at the lower end, and the other end of the reset spring 23 is fixedly connected with a sliding cavity 22. The box door 17 is movably installed on one side of the charging pile body 1. By opening the box door 17, the gas tank 10 can be replaced.

[0037] As shown in Figure 2 、 Figure 3 The clamping mechanism includes a T-shaped clamping rod 27, which is slidably connected in the receiving cavity 25. The receiving cavity 25 is formed in the charging pile body 1, and the supporting spring 26 is fixedly connected in the receiving cavity 25. The other end of the supporting spring 26 is fixedly connected with the T-shaped clamping rod 27. The electromagnet 24 is arranged on the inner side of the supporting spring 26. The model of the electromagnet 24 can be selected according to the corresponding size and model in use. The electromagnet 24 is fixedly installed in the receiving cavity 25. The clamping end of the T-shaped clamping rod 27 is arc-shaped. Since the lower end of the cross-shaped sliding block 19 is arc-shaped, and the clamping end of the T-shaped clamping rod 27 is arc-shaped, the T-shaped clamping rod 27 will be squeezed and moved into the receiving cavity 25 during the downward movement of the cross-shaped sliding block 19. At this time, the supporting spring 26 is compressed. When the T-shaped clamping rod 27 moves to the position of the clamping hole 39, the T-shaped clamping rod 27 will be clamped into the clamping hole 39 under the elastic force of the supporting spring 26.

[0038] The working principle is that when the car needs to be charged, the button 14 is pressed to start the electric telescopic rod 31, the two pull ropes 30 connected to the output end of the electric telescopic rod 31 start to move, the T-shaped limiting rod 28 moves into the sliding cavity 20, and the first spring 15 is compressed. At this time, the charging gun 3 can be pulled out of the plug hole 2, and after the plug 29 is pulled out, the plug 29 can be inserted into the charging port of the car. After the button 14 is released, the T-shaped limiting rod 28 is clamped into the charging port of the car under the elastic force of the first spring 15. At this time, the new energy vehicle can be charged. When the new energy vehicle moves with the charging gun 3, the cable 4 is moved, and under the limiting action of the limiting ring 7, the cross-shaped slider 19 moves downward. Because the two sides of the lower end of the cross-shaped slider 19 are arc-shaped, and the clamping end of the T-shaped clamping rod 27 is arc-shaped, the T-shaped clamping rod 27 is squeezed and moves into the storage cavity 25 during the downward movement of the cross-shaped slider 19. At this time, the supporting spring 26 is compressed. When the T-shaped clamping rod 27 moves to the position of the clamping hole 39, the T-shaped clamping rod 27 is clamped into the clamping hole 39 under the elastic force of the supporting spring 26. The pressing switch 8 in the clamping hole 39 is pressed, and the electric telescopic rod 31 and the electromagnetic valve 11 are opened;

[0039] After the electric telescopic rod 31 is started, the T-shaped limiting rod 28 is retracted into the sliding cavity 20. After the electromagnetic valve 11 is opened, the high-pressure gas in the gas tank 10 enters the telescopic pipe 18. The gas in the telescopic pipe 18 enters the gas guide pipe 5 through the guide cavity 21. Finally, the gas enters the annular air bag 33 through the gas guide cavity 34. After the annular air bag 33 is inflated, it expands outward and moves synchronously with the annular baffle 36. At this time, under the pushing of the annular air bag 33 and the annular baffle 36, the plug 29 is pulled out of the charging port of the car. At the same time, the annular air bag 33 that is rapidly inflated also wraps and protects the plug 29, preventing the plug 29 from falling to the ground and being damaged;

[0040] At the same time, the annular baffle 36 moves outward and synchronously moves the traction rope 37. When the annular air bag 33 completely wraps the plug 29, the annular baffle 36 straightens the traction rope 37. When the annular baffle 36 moves again, the traction rope 37 opens the travel switch 9. At this time, the electromagnetic valve 11 is closed, and the gas in the gas tank 10 does not enter the annular air bag 33, preventing the annular air bag 33 from exploding due to excessive inflation;

[0041] When the device needs to be reset, the T-shaped clamping rod 27 is adsorbed by opening the electromagnet 24, so that the T-shaped clamping rod 27 is received into the receiving cavity 25, at this time, under the elastic force of the reset spring 23, the cross-shaped sliding block 19 will rise to the initial position, and at the same time, by opening the valve 16, the annular air bag 33 can be deflated, and the annular air bag 33 and the annular baffle 36 are re-stored in the annular cavity 32. The magnetic ring 38 adsorbs the annular baffle 36, so that the annular baffle 36 is limited in the annular cavity 32, and the plug 29 is re-inserted into the jack 2.

[0042] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and changes can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
