Description

Technical Field

[0001] The present application relates to the technical field of new energy vehicle equipment, and specifically to a vehicle charging port with an automatically openable and closable inner cover and a new energy vehicle. Background Art

[0002] New energy vehicles (NEVs) use unconventional fuels as their power source (or use conventional fuels with new onboard power units). These vehicles utilize advanced technologies in vehicle power control and drive, resulting in advanced technical principles, new technologies, and new structures. Unconventional fuels refer to fuels other than gasoline, diesel, natural gas, liquefied petroleum gas, ethanol gasoline, methanol, and dimethyl ether. With the widespread adoption of NEVs, charging has become a daily necessity.

[0003] To protect charging ports from being exposed to the elements and exposed to dust, rain, and other external influences, charging ports are typically equipped with an outer cover and an inner cover. The outer cover opens and closes automatically, while the inner cover plugs directly into the charging port. However, when charging a car, the user typically needs to access the charging port, manually remove the inner cover, and then insert the charging plug into the port to charge. This is very inconvenient. Furthermore, when the charging plug is inserted into the charging port, some electrical energy is converted into heat between the charging plug and the port, generating heat. However, conventional charging ports and their inner covers lack thermal conductivity. Therefore, during charging, heat accumulates at the connection between the charging plug and the charging port. If this accumulated heat is not promptly removed, the charging port can overheat and produce a chemical reaction, leading to oxidation damage. This damage can easily pose a safety hazard. Therefore, we propose a car charging port and a new energy vehicle with an inner cover that opens and closes automatically. Summary of the Invention

[0004] In order to make up for the above shortcomings, the present application provides a car charging port and a new energy vehicle with an inner cover that can be opened and closed automatically, so as to solve the problem of the existing charging port proposed in the above background technology, whose outer covers are all opened or closed by an automatic opening and closing mechanism, and the inner covers are directly plugged into the charging port. When the car needs to be charged, the user is generally required to touch the charging port and then manually remove the inner cover of the charging port before inserting the charging head into the charging port to realize the charging operation, which is very inconvenient to use. At the same time, when the charging head is inserted into the charging port for charging, part of the electrical energy between the charging head and the charging port will be converted into heat energy, thereby generating heat. The general charging port and the inner cover at the charging port do not have thermal conductivity. Therefore, during the charging process, heat will continue to accumulate at the connection between the charging head and the charging port. When the accumulated heat is not discharged in time for a long time, the charging port will produce a chemical reaction due to the high temperature, which will cause oxidation damage to the charging port. If the charging port is damaged, it is easy to cause certain safety hazards.

When the charging socket 21 is not in use, the two semicircular covers 221 can be further magnetically attracted by the two magnets, thereby further ensuring the closed sealing effect. In addition, a dust filter 2216 is provided on the front side of the mounting groove 2213 of the two semicircular covers 221.

The right end of the first driven shaft 227, the first driven gear 226 and the driving gear 225 are all rotatably connected to the upper part of the left side slide groove 23. The right end of the first driven shaft 227 passes through the side wall of the left side slide groove 23 and extends into the upper part of the left side of the charging slot 2 and is rotatably connected to the upper part of the left side of the charging slot 2.

Each heat-conducting copper sheet 2214 is composed of a straight strip and an inclined sheet. The straight strip is arranged in the straight groove 2211, and one end of the straight strip is fixedly connected to the higher inclined end of the inclined sheet, and the other end of the straight strip passes through the straight groove 2211. The outer side of the semicircular cover 221 is provided with a heat dissipation fin 22145, and the heat dissipation fin 22145 is spiral. The higher inclined end of the inclined piece is arranged at the floating groove 2212, and the end is fixedly connected to the lower ends of the two springs 22143. The upper ends of the two springs 22143 are fixedly connected to the top of the floating groove 2212. The lower inclined end of the inclined piece is arranged in the charging socket 21, and the end contacts the surface of the charging head for charging and plugged into the charging socket 21. A plurality of grooves 22141 are provided on the side of the end in contact with the charging head, and a spiral channel 22142 is provided on the inner side wall of each groove 22141.

[0049] It should be noted that the buffer part 22144 is composed of an elastic pad 221441, a mounting sleeve 221442 and a buffer pad 221443.

[0052] It should also be noted that each shock absorber includes: four support frames 22151, the four support frames 22151 are respectively fixedly connected to the edges of the micro cooling fan 2215, and the four support frames 22151 are fixedly connected to the micro damper 22152, and the four micro dampers 22152 are fixedly connected to the side wall of the mounting groove 2213 at one end away from the connection of the four support frames 22151.

[0053] In this embodiment, a micro cooling fan 2215 is provided at each heat-conducting copper sheet 2214. The micro cooling fan 2215 can further dissipate the heat conducted on the surface of the heat-conducting copper sheet 2214, thereby preventing the heat of the heat-conducting copper sheet 2214 from accumulating in the straight groove 2211, thereby maximizing the heat dissipation effect of the heat-conducting copper sheet 2214. However, when using the micro cooling fan 2215, since the heat-conducting copper sheet 2214 is connected to the micro dampers 22152 on the four mounting grooves 2213 and then indirectly mounted in the mounting grooves 2213 through the four micro dampers 22152, the four micro dampers 22152 can evenly balance the vibration of the micro cooling fan 2215, provide stable support for the micro cooling fan 2215, thereby achieving the effect of noise reduction, and then ensuring the use effect of the micro cooling fan 2215, avoiding noise and bringing a bad user experience.

[0054] A new energy vehicle comprises a new energy vehicle body 1 and a vehicle charging port with an inner cover that can be opened and closed automatically. The vehicle charging port with an inner cover that can be opened and closed automatically is arranged on the new energy vehicle body 1.

[0055] In this embodiment, by providing a car charging port with an automatically openable and closable inner cover on the new energy vehicle body 1, the inner cover of the charging port can be automatically opened or closed without the user having to manually touch the inner cover of the charging port.

[0056] During specific use, when the new energy vehicle needs to be charged and the charging port is used, it is only necessary to press the car key or the button in the car of the new energy vehicle body 1. At this time, the servo motor will drive the drive shaft 224 to rotate a certain number of circles, and the drive shaft 224 will directly drive the bidirectional screw 223 to rotate. Since the bidirectional screw 223 is provided with threads in opposite directions, and the threads in opposite directions are respectively threadedly connected to the left slide 222 of the two semicircular covers 221, when the bidirectional screw 223 rotates, the two semicircular covers 221 will move away from each other under the guidance of the right slide 222 and the guide rod, thereby realizing the automatic opening of the two semicircular covers 221. At the same time, due to the connection between the bidirectional screw 223 and the drive shaft 224 A driving gear 225 is connected to the joint, and the driving gear 225 and the first driven gear 226 on the first driven shaft 227 are meshed with each other. Therefore, under the meshing action of the driving gear 225 and the first driven gear 226, the driving shaft 224 will synchronously and indirectly drive the first driven shaft 227 to rotate, and the second driven gear 228 on the first driven shaft 227 is meshed with the third driven gear 229 on the second driven shaft 2210. Therefore, under the meshing action of the second driven gear 228 and the third driven gear 229, the first driven shaft 227 can drive the second driven shaft 2210 to rotate. At this time, the second driven shaft 2210 can synchronously drive the charging cover 3 connected to the front side of the rotating column to rotate, thereby realizing the automatic opening of the charging cover 3;

[0057] Afterwards, the user only needs to plug the charging head into the charging socket 21 to realize the charging operation, and the user does not need to manually open the inner cover of the charging port, which improves the convenience of use. However, when the charging head and the charging socket 21 are plugged in, the inclined plate will be able to cling to the surface of the charging head under the elastic deformation of the two springs 22143, and a plurality of grooves 22141 are provided on the side of the inclined plate that contacts the charging head. The setting of the plurality of grooves 22141 can increase the contact area between the inclined plate and the charging head, which can effectively improve the heat conduction effect of the inclined plate, and each groove 22141 is provided with a spiral channel 22142. After the heat is transferred to each groove 22141, a spiral fluid path can be formed. At this time, the heat can be dispersed to a larger surface area, thereby further improving the heat conduction effect of the inclined plate. Therefore, during the charging process, the heat conductive copper The inclined piece of the sheet 2214 can directly and effectively transfer the heat from the contact with the charging head to the straight piece, and then directly and smoothly transfer the heat from the straight groove 2211 to the outside of the semicircular cover 221 through the straight piece, and then dissipate the heat through the provided heat dissipation fins 22145. Since the heat dissipation fins 22145 are spiral-shaped, the thread shape can increase the contact area between the heat and the straight piece, thereby improving the efficiency of heat transfer and achieving the effect of rapid heat dissipation. At the same time, the provided micro cooling fan 2215 can further dissipate the heat conducted on the surface of the thermally conductive copper sheet 2214, preventing the heat of the thermally conductive copper sheet 2214 from accumulating in the straight groove 2211, thereby maximizing the heat dissipation effect of the thermally conductive copper sheet 2214, thereby avoiding excessive heat in the charging port during charging, ensuring the safety of the charging port, and also avoiding damage to the charging port and affecting the service life of the charging port.

[0058] Finally, when the charging head is plugged into or unplugged from the charging socket 21 and contacts the thermal copper sheet 2214, the thermal copper sheet 2214 will transfer the impact force it receives to the buffer pad 221443. At this time, the buffer pad 221443 will initially buffer the impact force received by the thermal copper sheet 2214 and protect the thermal copper sheet 2214. The buffer pad 221443 will further transfer the buffering force to the elastic pad 221441 under the connection of the mounting sleeve 221442, and the elastic pad 221443 will further transfer the buffering force to the elastic pad 221441 through the elastic pad 221443. The elastic deformation of the elastic pad 221441 can avoid direct collision between the heat-conducting copper sheet 2214 and the straight groove 2211, which would cause noise, thereby achieving the effect of noise reduction; and when using the micro cooling fan 2215, the four micro dampers 22152 set up can evenly balance the vibration of the micro cooling fan 2215, provide stable support for the micro cooling fan 2215, and thus achieve the effect of noise reduction for the micro cooling fan 2215, so as to avoid a bad user experience.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
