[0001] The present invention relates to the technical field of charging guns, and in particular to a charging gun heating device and a charging gun for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and new onboard power units), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles require a charging gun when charging. Currently, most public charging stations are installed in open-air parking lots. In winter, due to the low temperature, it is cold to pick up the charging gun, making it less comfortable.

[0032] See also Figure 1-9 The technical solution provided by the present invention specifically includes the following embodiments:

[0033] A charging gun heating device for a new energy vehicle includes a charging gun 1, wherein the charging gun 1 is composed of a gun body 11, a gun head 12, and a gun handle 13;

[0034] A main heating component 2 is installed inside the gun handle 13, and the main heating component 2 is used to heat the gun handle 13;

[0035] An adjustment component 3 is installed inside the gun handle 13, and the adjustment component 3 is used to adjust the position of the main heating component 2;

[0036] A heat transfer component 4 is installed inside the gun body 11, and is used to conduct heat inside the gun handle 13 to the socket of the gun head 12;

[0037] A secondary heating component 5 is installed inside the gun head 12, and the secondary heating component 5 is used to receive the heat transferred from the heat transfer component 4 and heat the inside of the gun head 12 socket.

[0038] The main heating component 2 has two symmetrically distributed heat insulation plates 21, and an electric heating plate 22 is fixedly connected to the outside of the heat insulation plate 21. Two ear plates 23 are fixedly connected to the end of the heat insulation plate 21. A plurality of guide rods 25 are fixedly connected to the inside of the gun handle 13. The guide rods 25 pass through the ear plates 23, and the ear plates 23 and the guide rods 25 are movably connected. A tension spring 24 is fixedly connected between the two adjacent ear plates 23 on the left and right, and the tension spring 24 is sleeved on the outer end of the guide rod 25.

[0039] The electric heating plate 22 in the main heating assembly 2 can be used as a heat source. When the electric heating plate 22 contacts the rectangular ceramic tube 131 on the inner wall of the gun handle 13, it can transfer heat to the gun handle 13 more quickly to heat it, thereby improving its grip comfort. When the electric heating plate 22 no longer contacts the rectangular ceramic tube 131, heat can only be transferred through the air, thereby reducing the heating efficiency of the gun handle 13 and avoiding the problem of overheating caused by unlimited heating of the gun handle 13.

[0040] The adjustment assembly 3 includes a shaft 31, which is movably connected to the inside of the gun handle 13. The outer end of the shaft 31 is fixedly connected to two special-shaped wheels 32. The shaft 31 and the special-shaped wheels 32 are both located between the two heat insulation plates 21, and the two short shaft ends of the special-shaped wheels 32 are respectively in contact with the inner sides of the two heat insulation plates 21. A stepper motor 33 is fixedly connected to the bottom inside the gun handle 13. The output shaft of the stepper motor 33 and the outer end of the shaft 31 are fixedly connected to a bevel gear 34, and the two bevel gears 34 are meshed with each other.

[0041] When adjusting whether the electric heating plate 22 contacts the rectangular ceramic tube 131, the shaped wheel 32 can be driven to rotate by the shaft 31 for adjustment. When the short axis end of the shaped wheel 32 is against the inner side of the heat insulation plate 21, the two heat insulation plates 21 are pulled closer to each other by the elastic force of the tension spring 24, so that the electric heating plate 22 will move away from the rectangular ceramic tube 131. Conversely, when the long axis end of the shaped wheel 32 is against the inner side of the heat insulation plate 21, the two heat insulation plates 21 will be pushed away from each other until the electric heating plate 22 is attached to the inner wall of the rectangular ceramic tube 131, so that rapid heat conduction can be achieved to heat the handle 13.

[0042] The bottom inner side of the gun handle 13 is integrally formed with a motor cover 132, and the stepper motor 33 is located inside the motor cover 132. An air vent 133 is provided on the outer side wall of the motor cover 132, and a filter plate 134 is fixedly connected to the inside of the air vent 133. A plurality of air inlets 135 are provided on the inner side of the gun handle 13, and the interior of the gun handle 13 and the interior of the motor cover 132 are connected through the air inlets 135.

[0043] The motor cover 132 can protect the stepper motor 33 inside. When only the handle 13 is heated, the air vent 133 can be used as a heat dissipation vent when the stepper motor 33 is running. When the gun head 12 needs to be heated at the same time, the air vent 133 and the air inlet 135 are both used as air inlets. The wind entering from the air vent 133 will also dissipate heat for the stepper motor 33 when blowing through it. The filter plate 134 prevents dust or mosquitoes from entering the motor cover 132 and the handle 13 through the air vent 133, thereby playing a protective role.

[0044] An installation chamber 111 for installing a heat transfer component 4 is provided inside the gun body 11. The heat transfer component 4 includes an air pump 41, which is fixedly connected to the inside of the installation chamber 111. The air inlet of the air pump 41 is fixedly connected to an air duct 1 42, and the end of the air duct 1 42 is connected to the inside of the gun handle 13. The air outlet of the air pump 41 is fixedly connected to an air duct 2 43, and the end of the air duct 2 43 is fixedly connected to a connecting pipe 44. The air duct 2 43 is located inside the installation chamber 111 and extends to the inside of the gun head 12. The connecting pipe 44 is embedded in and connected to the inside of the gun head 12.

[0045] The heat transfer component 4 can guide the hot air in the handle 13 to the secondary heating component 5, so that the heat generated by the main heating component 2 can be fully utilized, and there is no need to install electric heating components in the secondary heating component 5.

[0046] The secondary heating component 5 includes a plurality of heat-conducting ceramic rings 51, and the plurality of heat-conducting ceramic rings 51 are respectively embedded in the inner walls of a plurality of sockets connected to the gun head 12. An S-shaped air duct 52 is opened inside the heat-conducting ceramic ring 51, and the air inlet and air outlet of the S-shaped air duct 52 are respectively fixedly connected to an air inlet pipe 53 and an air outlet pipe 54. The end of the air inlet pipe 53 is fixedly connected to the connecting pipe 44, and the end of the air outlet pipe 54 is connected to the inside of the socket of the gun head 12.

[0047] After entering the S-shaped air duct 52, the hot air can fully transfer the heat in the air to the thermally conductive ceramic ring 51, and the heat of the thermally conductive ceramic ring 51 can melt the outer layer of the ice in the socket of the gun head 12. At this time, the ice can move in the socket of the gun head 12. Then, the air discharged from the air outlet pipe 54 into the socket of the gun head 12 can blow out the moving ice in the socket of the gun head 12 until the socket of the gun head 12 becomes dry.

[0048] A rectangular ceramic tube 131 is embedded on the inner wall of the gun handle 13 , and temperature sensors 6 are embedded on both the inner and outer sides of the gun handle 13 .

[0049] The rectangular ceramic tube 131 and the thermally conductive ceramic ring 51 both have good thermal conductivity, thereby achieving the purpose of rapid and uniform heating. The temperature sensor 6 can be used to detect the outer surface temperature of the gun handle 13. If the charging gun 1 is not inserted into the charging pile but is directly dropped on the ground, the detected temperature at this time is also the ambient temperature of the charging gun 1.

[0050] A humidity sensor 7 is embedded on the inner wall of the jack depth of the gun head 12. The humidity in the jack of the gun head 12 can be detected by the humidity sensor 7 to determine whether there is ice or water in the jack of the gun head 12.

[0051] A charging gun includes a charging gun 1, wherein the charging gun 1 is composed of a gun body 11, a gun head 12 and a gun handle 13, and also includes any of the above-mentioned charging gun heating devices for new energy vehicles.

[0052] Working principle:

[0053] When the charging gun 1 is normally inserted into the charging pile, the temperature sensor 6 detects the temperature of the outer surface of the gun handle 13. When the temperature is lower than the set threshold, the electric heating plate 22 starts to heat up. At the same time, the stepping motor 33 is started and drives the shaft 31 to rotate through the meshing transmission of the two bevel gears 34. When the shaft 31 rotates, it drives the two special-shaped wheels 32 to rotate. When the special-shaped wheels 32 rotate, their two long axis ends gradually push toward the inner side of the heat insulation plate 21 until the long axis ends of the special-shaped wheels 32 vertically press against the inner side of the heat insulation plate 21. At this time, the two heat insulation plates 21 will move away from each other and make the two electric heating plates 22 stick to the inner wall of the rectangular ceramic tube 131. Then the heat of the electric heating plate 22 is transferred through the heat of the rectangular ceramic tube 131 to finally heat the gun handle 13, making the hand feel more comfortable when holding the gun handle 13 during use.

[0054] When the charging gun 1 is not plugged into the charging pile but is thrown on the ground at random, the temperature sensor 6 detects the temperature of the outer surface of the gun handle 13. At this time, the temperature detected by the temperature sensor 6 is also the ambient temperature of the charging gun 1. At the same time, the humidity sensor 7 detects the humidity in the jack of the gun head 12. When the humidity detected by the humidity sensor 7 exceeds the set value, it means that water may have entered the jack of the gun head 12. If the temperature detected by the temperature sensor 6 is lower than zero degrees, it means that there may be ice in the jack of the gun head 12. Then, the charging of the gun handle 13 is carried out according to the above operation. Heat is generated, and the heat transfer component 4 is activated at the same time. The heat transfer component 4 draws the hot air out of the gun handle 13 and guides it to the secondary heating component 5. The hot air flows into the S-shaped air duct 52 in the heat-conducting ceramic ring 51. During this period, the heat in the hot air is evenly transferred to the heat-conducting ceramic ring 51. At this time, the heat of the heat-conducting ceramic ring 51 can melt the ice in the socket of the gun head 12. As the ice is initially melted and no longer frozen on the inner wall of the socket of the gun head 12, the residual air discharged from the air outlet pipe 54 enters the socket of the gun head 12 and blows out the moving ice.

[0055] During this period, if the temperature sensor 6 detects that the temperature of the gun handle 13 reaches the set temperature, the distance between the two heat insulation plates 21 can be adjusted through the adjustment component 3. When the long axis end of the shaped wheel 32 no longer supports the heat insulation plate 21, the elastic tension of the tension spring 24 will pull the two heat insulation plates 21 closer to each other, so that the electric heating plate 22 is no longer attached to the inner wall of the rectangular ceramic tube 131. At this time, the heat of the electric heating plate 22 is difficult to be efficiently transferred to the rectangular ceramic tube 131 through air heat conduction. At the same time, due to the operation of the heat transfer component 4, air circulation is also allowed inside the gun handle 13. Therefore, the main heating component 2 will not heat the gun handle 13 without limit, but will not affect the de-icing heating inside the gun head 12. When the humidity sensor 7 detects that the inside of the gun head 12 socket is dry, it means that there is no ice or water in the gun head 12. At this time, the main heating component 2 can stop running.
