Description

Technical Field

[0001] This utility model belongs to the field of charging plug technology, and specifically relates to a highly stable charging plug for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source or use conventional vehicle fuels and adopt new on-board power devices, integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles, new technologies, and new structures. Among them, electric vehicles refer to new energy vehicles that use on-board power sources as power sources and use electric motors to drive the wheels. Due to the advantages of electric vehicles such as no pollution, low noise, high energy efficiency, simple structure, and convenient maintenance, electric vehicles have a very good development prospect. At present, the new energy vehicle field is developing rapidly, and electric vehicles or hybrid vehicles are becoming more and more popular.

[0003] A search revealed that Chinese patent CN216231710U discloses a charging plug for a new energy vehicle, comprising a gun housing, a charging head, and a heat sink. The upper surface of the gun housing has a channel, and a moving mechanism is slidably connected inside the channel. The moving mechanism is used to adjust the position of the charging head. The right side of the charging head is electrically connected to a charging cable, which is disposed inside the gun housing. The front and back of the gun housing have mounting holes for installing the heat sink, which is used to dissipate heat outward.

[0004] In the charging plug structure described above, a heat sink with heat dissipation holes is installed at the mounting port on the outside of the gun housing. Although this can provide some heat dissipation protection for the electronic components inside the gun housing, the heat dissipation effect is not significant. Furthermore, while the heat dissipation holes can facilitate heat dissipation, they can also allow dust and moisture to enter, thereby accelerating the aging of the electronic components inside the charging plug body and reducing its service life.

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a highly stable charging plug for new energy vehicles to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A highly stable new energy vehicle charging plug includes a charging plug body, a connector at the left end of the charging plug body, a protective mechanism inserted into the outside of the connector, a connecting wire at the right end of the charging plug body, a heat dissipation mechanism on the front of the charging plug body, and a hanging block fixedly installed at the upper end of the charging plug body.

[0008] The heat dissipation mechanism includes a square hole on the front of the charging plug body. A fixing groove is provided at the opening of the square hole. A heat-conducting plate is inserted into the inner side of the fixing groove. A sealing groove is provided on the inner side of the fixing groove. A sealing ring is fixedly installed on the outer side of the heat-conducting plate. The heat-conducting plate is fixedly installed on the inner side of the fixing groove by screws.

[0010] As a preferred technical solution, a positioning groove is provided at the opening of the protective cover, and the protective cover is connected to the electrical connector through the positioning groove.

[0011] As a preferred technical solution, a first end seat is fixedly installed on the side of the cover plate away from the protective cover, a second end seat is fixedly installed on the lower end of the charging plug body, one end of the connecting chain is rotatably connected to the inside of the first end seat, and the other end of the connecting chain is rotatably connected to the inside of the second end seat.

[0012] As a preferred technical solution, the cooling fan has a first through hole symmetrically opened on its inner side, and the heat-conducting plate has a first screw groove opened on its front side. The cooling fan is fixedly installed by screws passing through the first through hole and the first screw groove of the heat-conducting plate.

[0013] As a preferred technical solution, the heat-conducting plate has symmetrically opened second through holes on its inner side, and the fixing groove has opened second screw grooves on its inner side. The heat-conducting plate is fixedly installed by screws passing through the second through holes and the second screw grooves of the charging plug body.

[0014] As a preferred technical solution, a limiting groove is formed on the front of the heat sink, one side of the cooling fan is inserted into the limiting groove, and mating grooves are symmetrically formed on the back of the cooling fan. A mating block is fixedly installed on the outer side of the heat conduction plate, and one end of the mating block is inserted into the mating groove.

[0015] In summary, the present invention has the following main advantages:

[0016] First, by fixing the heat-conducting plate to the fixing groove of the charging plug body, the sealing ring on the heat-conducting plate is pressed into the sealing groove of the fixing groove under the pressure to seal the gap. During use, the wave-shaped heat-absorbing sheet on one side of the heat-conducting plate can expand the contact surface and quickly transfer the heat inside the charging plug body from the heat-conducting plate to the heat sink. The heat sink with heat dissipation grooves can quickly dissipate the heat. At the same time, the cooling fan on the heat-conducting plate can further accelerate the heat dissipation effect of the heat sink, thereby improving the heat dissipation effect while ensuring the sealing effect, effectively preventing the entry of moisture and dust, and thus to a certain extent enhancing the service life of the charging plug body.

[0017] Secondly, the protective cover connected to the lower end of the charging plug body is positioned and inserted into the connector of the charging plug body. During the insertion process, under the pressure, the rubber sleeve is inserted into the connector, which can achieve a connection and provide a certain degree of waterproofing. At the same time, the plug inside the protective cover is also inserted into the connector port and contacts the conductive metal inside. This can prevent the conductive parts inside the connector port from falling off due to excessive vibration during use, thus providing effective protection for the charging plug body.
