Description

Technical Field

[0001] The present invention relates to the field of charging connectors, and particularly to an intelligent charging connector for new energy vehicles. Background Art

[0002] In winter, when new energy vehicles in the north are charging, especially in rainy or snowy weather, the charging gun is extremely likely to be frozen at the charging port of the new energy vehicle, resulting in the inability to pull it out, and even unable to disconnect from the charging port by pressing the switch. Due to being in a low temperature environment for a long time, touching the charging gun with hands will also bring a stress stimulus to people, causing strong discomfort, which brings inconvenience to people's travel; although some vehicle models themselves have a certain defrosting and heating function, the defrosting effect is not good; even worse, pouring hot water or using a hair dryer on the charging port still has a poor effect and is very troublesome, and people are in the external environment for a long time, and the body feeling will also be uncomfortable;

Detailed implementation manners

[0036] Example 1:

[0037] Please refer to Figures 1-13 , the present invention provides a technical solution: AsFigure 1 As shown in the figure, a smart charging connector for new energy vehicles includes a gun body 1 and a gun head 2. The gun body 1 and the gun head 2 are fixedly connected for charging an electric vehicle. A gas carrier 3 is sleeved on the outer wall of the gun head 2. One side of the gas carrier 3 close to the gun body 1 is fixedly connected to the gun body 1. A plurality of cavities are provided inside the gas carrier 3. A gas delivery member 4 is fixedly connected to the lower side of the gas carrier 3. A heating device 5 is fixedly connected to the lower side of the gun body 2. When transporting, the heating device 5 can generate hot gas. The gas delivery member 4 can be threadedly connected to the heating device 5. The hot gas is transported to the gas carrier 3 through the gas delivery member 4 and distributed to the gun body 1 or the gun head 2 by the gas carrier 3 to heat the gun body 1 or the gun head 2.

[0038] As Figures 1-6 shown, a cavity one 31 is provided inside the gas carrier 3. The head and tail ends of the cavity one 31 are communicated (see Figure 5 ), such as in a ring shape. The gas carrier 3 is fixedly connected to the gas delivery member 4 and internally communicated through the cavity one 31. A plurality of heating holes 21 are provided on the outside of the gun head 2. The heating holes 21 are distributed along the outer circumference of the gun head 2. A heating air duct 22 is communicatedly provided corresponding to each group of heating holes 21. The cross-section enclosed by the plurality of heating air ducts 22 matches the cavity one 31. One end of the heating air duct 22 is closed and the other end is communicated with the cavity one 31. The gun head 2 and the charging port of the electric vehicle in contact with the outer wall of the gun head 2 are heated by using the heating air duct 22 and the heating holes 21.

[0039] A seal 23 is nested on the outer wall of the gun head 2. The seal 23 is close to the connection between the gun head 2 and the gas carrier 3, and the side surface thereof is attached to the gas carrier 3. The seal 23 is preferably made of a material with a certain flexibility, such as rubber, to improve the sealing performance during charging.

[0040] A cavity two 32 is also provided inside the gas carrier 3 (see Figure 6 ). The cavity two 32 is adjacent to and communicated with the cavity one 31. The air volume carried by the cavity two 32 is larger than that of the cavity one 31. A plurality of heating nozzles 33 are provided on one side of the gas carrier 3 close to the gun head 2. The heating nozzles 33 are communicated with the cavity two 32. The hot gas blows from the heating nozzles 33 to the connection between the gun head 2 and the gas carrier 3 to prevent the connection from being locked due to low temperature and unable to be disengaged. The lower side of the outlet end of the heating nozzle 33 is arc-shaped, and a wind guiding slope 331 for guiding the hot air to blow towards the connection is provided on the upper side. A pair of air ducts one 34 extend upward from the gas carrier 3. The air ducts one 34 are fixedly connected to the upper side of the gun body 1.

[0041] As Figure 1 and Figures 7-9As shown, the gun body 1 includes a gun body main body 11 and a limit switch member 12. The limit switch member 12 is fixedly connected to the upper side of the gun body main body 11 and is used to lock the gun head 2 to the charging port. The limit switch member 12 includes a limit housing 121 and a limit assembly 122. The limit assembly 122 is slidably installed in the limit housing 121. The limit housing 121 is fixedly connected to the upper side of the gun body main body 11. An air duct cavity 1211 is formed inside the limit housing 121. The outer side of the air duct cavity 1211 communicates with the first air duct 34, and the inner side of the air duct cavity 1211 communicates with a second air duct 13. The second air duct 13 is fixedly connected to the limit assembly 122. By pressing the limit assembly 122, it is controlled whether the hot air flows from the second air duct 13 to the limit assembly 122;

[0042] The limit assembly 122 includes a limit rod 14, a first spring 15, and a control member 16. One end of the limit rod 14 extends out of the limit housing 121, and the other end is inserted into the lower side of the control member 16. The middle of the limit rod 14 is rotatably connected to the inner side wall of the limit housing 121. The control member 16 is located in a groove formed at the end of the limit housing 121 away from the gas carrier 3. A first spring 15 is fixedly connected to the lower side of the control member 16. By pressing the control member 16, the control member 16 compresses the first spring 15 and presses the limit rod 14 downward, causing one end of the limit rod 14 to move upward, so as not to prevent the gun head 2 from being inserted into the charging port. When the control member 16 is released, the first spring 15 pushes the control member 16 upward, and the control member 16 drives one end of the limit rod 14 to move upward, causing the other end of the limit rod 14 to move downward and be snap-connected to the charging port;

[0043] The limit assembly 122 further includes a heating member 17; the middle of the heating member 17 is hollowed out, and a heating port 171 is formed on the side facing the first spring 15. A positioning plate 172 extends downward from the lower side of the heating port 171. The second air duct 13 is fixedly connected to the side of the heating member 17 and is internally communicated, so as to blow the hot air through the heat outlet 171 towards the first spring 15 to heat the limit assembly 122. A clamping plate 161 is fixedly connected to the side of the control member 16 close to the heating member 17. The clamping plate 161 is located inside the limit housing 121. The clamping plate 161 matches the heat outlet 171. The control member 16 is also provided with a card slot 162. The card slot 162 is located above the clamping plate 161. The card slot 162 matches the edge of the limit housing 121 on the opposite side (see Figure 9 ), when pressing the control member 16 downward, when the clamping plate 161 contacts the positioning plate 172, the control member 16 can be moved towards the heating member 17, so that the clamping plate 161 is inserted into the heat outlet 171. At this time, the edge of the limit housing 121 is located in the card slot 162 to block the heat outlet 171 and prevent the hot air from pouring into the inside of the limit housing 121; the lower side of the first spring 15 and the lower side of the heating member 17 are fixedly connected to the inner wall of the limit housing 121.

[0044] As Figures 1 to 2 and Figures 10 to 12As shown, the gas delivery member 4 includes a delivery pipe 41 and a protective cover 42. One end of the delivery pipe 41 is fixedly connected to the lower side of the gas carrier 3 and communicates with the first cavity 31. The other end is fixedly connected to the protective cover 42 and communicates with the inside of the protective cover 42. A starting ring 421 is fixedly connected to the bottom of the protective cover 42, and the other end of the delivery pipe 41 is located inside the starting ring 421. The protective cover 42 is sleeved outside the heating device 5, and the heating device 5 is opened through the starting ring 421, so that the inside of the heating device 5 communicates with the inside of the protective cover 42, and the hot air flows towards the delivery pipe 41.

[0045] The heating device 5 can be remotely controlled through a mobile terminal. The heating device 5 includes a heating shell 51 and a heating component 52. The heating shell 51 is fixedly connected to the lower side of the gun body 11 and is located at the end of the gun body 11 away from the gas carrier 3. The heating component 52 is fixedly connected to the proximal end of the heating shell 51 close to the gun body 11. An extension ring 511 is fixedly connected to the distal end of the heating shell 51 close to the outside. A pair of protective plates 512 are rotatably connected inside the extension ring 511. The protective plates 512 can rotate towards the inner wall of the heating shell 51. The diameter of the pair of protective plates 512 matches the outer diameter of the starting ring 421. When the protective cover 42 is entirely sleeved outside the heating shell 51, the starting ring 421 can push the pair of protective plates 512 open to a state perpendicular to the extension ring 511. An elastic member 513 is fixedly connected to the inner wall of the heating shell 51. The elastic member 513 includes a second spring 53 and a rotating plate 54. The lower end of the rotating plate 54 is rotatably connected to the inner wall of the heating shell 51. One end of the second spring 53 is fixedly connected near the upper end of the rotating plate 54, and the other end of the second spring 53 is fixedly connected to the inner wall of the heating shell 51. The upper end of the rotating plate 54 can be located within the diameter range enclosed by the pair of protective plates 512 in the natural state of the second spring 53. A traction rope 514 is fixedly connected between the pair of protective plates 512. After the protective cover 42 is withdrawn, the second spring 53 can push the rotating plate 54 to rotate towards the protective plate 512, thereby pushing one of the protective plates 512 to rotate towards the distal end of the heating shell 51. During the rotation of one of the protective plates 512, the other protective plate 512 can be driven to rotate towards the distal end of the heating shell 51 through the traction rope 514, so as to close the port of the heating shell 51 and prevent external dust and other impurities from entering. The heating shell 51 and the protective cover 42 are detachably fixedly connected. For example, threads are provided on the outer wall of the heating shell 51 near one end of the heating shell 51, and corresponding threads are provided on the inner wall of the protective cover 42. After the protective cover 42 is sleeved outside the heating shell 51, it is fixed through threaded connection. The diameter of the protective cover 42 is greater than or equal to the outer wall diameter of the gun head 12, and the protective cover 42 can also be sleeved outside the gun head 12.

[0046] The heating component 52 includes a motor, a plurality of fan blades and a heating wire. The fan blades are fixedly connected to the outer wall of the driving shaft of the motor. The motor is fixedly connected to one end of the heating shell 51. The heating wire is fixedly connected to the inner wall of the heating shell 51 and is located below the fan blades. When the motor drives the fan blades to rotate, the generated air volume is heated when passing through the heating wire and then flows towards the protective cover 42.

[0047] As Figure 13 shown, a plurality of air inlet holes are formed on the surface of the extension ring 511. The air inlet holes extend towards the conveying pipe 41 to penetrate the protective cover 42, so that the inside of the heating shell 51 is communicated with the outside of the protective cover 42 through the air inlet holes, and is used to provide air volume for the fan.

[0048] Working principle: When in the charging state, the protective cover 42 is sleeved outside the heating shell 51. When it is frozen, the user starts the heating component 52 through the mobile terminal to generate hot air. The hot air flows from the inside of the heating shell 51 to the conveying pipe 41, and then flows through the conveying pipe 41 to the cavity 31 inside the gas carrier 3. At the cavity 31, the hot air is divided. Part of the hot air flows from the cavity 31 to the heating air duct 22, then flows through the heating air duct 22 to the heating hole 21, and finally flows out from the heating hole 21, so as to heat up the outside of the gun head 21 and the charging port in contact with the outside of the gun head 21; Another part of the hot air flows through the cavity 32, flows from the cavity 31 to the heating nozzle 33 and flows to the air duct 34. The gas at the heating nozzle 33 flows towards the sealed connection of the seal 23 to heat up the sealed connection and thaw the sealed connection; The hot air flowing to the air duct 34 flows through the air duct cavity 1211 and the air duct 13 to the heating part 17 and flows out from the heating port 171 of the heating part 17 to heat up and thaw the limiting components 122 such as the first spring 15;

[0049] After heating for a certain period of time, press the control part 16. If the control part 16 cannot be pressed down due to freezing, continue heating. If it can be pressed down and still cannot be pulled out from the charging port, it means that the outside of the gun head 2 and the charging port are still frozen. At this time, press down the control part 16 until the clamping plate 161 contacts the positioning plate 172, and then move the control part 16 towards the heating part 17 to insert the clamping plate 161 into the heating port 171 to prevent the hot air from flowing out from the heating port 171. At this time, the edge of the limiting shell 121 near the card slot 162 is located in the card slot 162, so that more hot air flows to the cavity 31 to increase the heating and thawing effect on the sealed connection until the gun head 2 can be pulled out from the charging port.

[0050] After the charging is completed and the gun head 2 is removed from the charging port, unscrew the protective cover 42, then pull the protective cover 42 out from the outside of the heating shell 51 and put it on the gun head 2, and place it on the charging pile to prevent dust and the like from entering the inside of the gun head 2 or blocking the heating holes 21, and then turn off the heating component 52 through the mobile terminal; after the protective cover 42 is pulled out, at this time, under the elastic force of the second spring 53, the rotating plate 54 is pushed to rotate towards the distal end direction of the heating shell 51, and the other rotating plate 54 is driven to rotate through the traction rope 514, so as to seal the port of the heating shell 51 and prevent dust and the like from entering.

[0051] When using it again, pull the protective cover 42 out from the gun head 2 and then put it on the outside of the heating shell 51, and then fix it by threading. At this time, as the starting ring 421 gradually moves towards the gun body main body 11 direction along with the protective cover 42, it will abut against the protection plate 512 and force the protection plate 512 to rotate towards the inner wall direction of the heating shell 51. At the same time, the protection plate 512 pushes the rotating plate 54 to move towards the inside direction of the heating shell 51 until the protective cover 42 is fixed to the heating shell 51. At this time, the traction rope 54 is straightened and the second spring 53 is compressed, completing the connection of the gas delivery member 4 with the gas bearing member 3 and the heating device 5; when pulling out again after the charging is completed, the specific operation method is the same as above, and the heating component 52 is started to perform heating and thawing.
