Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and in particular to a charging port device for a new energy vehicle. Background Art

[0002] New energy vehicles refer to vehicles that use batteries as a power source. Such vehicles rely entirely on battery packs for power, do not require fuel engines, and have zero emissions and low noise, making important contributions to environmental protection. The drive motors of new energy vehicles mostly use AC asynchronous motors or permanent magnet synchronous motors, which are powered by power batteries. New energy vehicles mainly include the following categories: Pure electric vehicles: Use built-in batteries as the only power source. The cruising range is affected by the battery capacity and is suitable for short-distance travel and medium- and low-distance driving. Plug-in hybrid electric vehicles (PHEV): These vehicles have both internal combustion engines and electric motors, and can achieve two modes of pure electric driving and internal combustion engine driving. When the battery is low on power, it can be charged through an external power supply. Fuel cell vehicles (FCEV): Use hydrogen as fuel, and convert hydrogen and oxygen into electricity through fuel cells to supply electric motors to drive the vehicle. Fuel cell vehicles have the characteristics of zero emissions, short refueling time, and long cruising range, but the current cost is relatively high. Solar vehicles: Use solar energy as the main energy source, store part of the electricity in batteries or power batteries, and use it to drive the vehicle. Although this type of car has a limited range, it can be effectively charged using solar energy in outdoor environments. In recent years, the Chinese government has strongly supported the development of the new energy vehicle industry and introduced a series of preferential policies, such as exemption from purchase tax, subsidies for car purchases, and free license plates, to encourage consumers to buy and use new energy vehicles. At the same time, major manufacturers have also launched various types of new energy vehicles to meet the needs of different consumers. In the future, with the advancement of battery technology, the improvement of charging facilities, and the adjustment of relevant policies, new energy vehicles will become one of the mainstream means of transportation.

[0003] The charging port cover is installed on the charging port to protect the internal circuit and prevent water from splashing into the charging port. It is usually made of conductive materials to ensure good conductivity. At the same time, the cover should have good sealing to prevent dust, impurities, water and other substances from entering the charging port. The design and selection of the charging port cover should take many factors into consideration. First, it is necessary to ensure that the cover can completely cover and seal the charging port to prevent water from splashing in. Secondly, the material of the cover should have good wear resistance and corrosion resistance to ensure long-term use. In addition, the size and shape of the cover also need to be adapted to the size and shape of the charging port for easy installation and use. In some public places, such as parking lots, charging stations, etc., the design and selection of the charging port cover is particularly important. If the design of the charging port cover is unreasonable, it may cause users to encounter various problems during use, such as failure to charge normally, slow charging speed, etc. Therefore, the design and selection of a suitable charging port cover is the key to ensuring safe and fast charging of electric vehicles.

The new energy vehicle charging port device includes a cover plate 2 and a mounting tube 3. The mounting tube 3 is installed inside the vehicle body and corresponds to the position of the charging port opened on the vehicle body panel 1 to form a charging docking cavity. The vehicle body panel 1 is the surface of the vehicle body, and the charging port is an open notch structure opened on the vehicle body panel 1. The charging port can be a rectangular, circular or other structure, among which the circular structure is preferred. Because the charging gun is basically cylindrical, the charging port structure is also preferably a circular structure. Of course, the setting of other structures is not excluded, and it can be set according to actual needs. The charging head can be installed inside the mounting tube 3, and the specific setting will not be repeated here.

[0030] The cover plate 2 is provided with multiple pieces, which are rotatably connected to the port in the charging docking cavity. When the cover plate 2 is rotated and docked to close, the charging head can be covered, thereby protecting the charging head inside the mounting tube 3. When charging is required, the cover plate 2 is rotated apart to display the charging head, thereby facilitating charging. When the cover plate 2 is closed, a circular plate-like structure is formed, which can protect the circular charging port. The cover plate 2 is arranged inside the vehicle body, on the inner side of the vehicle body panel 1, and the rotation direction is to rotate toward the vehicle body, avoiding interference from external objects, and is beautiful and generous. The optimal number of cover plates 2 is 2, so the shape of the cover plate 2 is a semicircular structure, and the two cover plates 2 are closed to form a circular structure. The cover plate 2 is set in two, which can minimize the rotation width of the cover plate 2 and the length of the mounting tube 3. The mounting tube 3 may include a cylindrical portion 5 and a square cylindrical portion 6, the cylindrical portion 5 and the square cylindrical portion 6 are fixedly connected, and the two cover plates 2 are relatively rotatably connected inside the square cylindrical portion 6, thereby facilitating the rotation of the cover plate 2 and avoiding rotation interference.

When the sliding block 13 slides in one direction on the mounting tube 3, the two racks 11 slide in this direction, thereby pushing the two rotating shafts 9 to rotate in opposite directions, so that the cover plate 2 rotates in the same direction and the cover plate 2 is opened. When the sliding block 13 slides in another direction on the mounting tube 3, the two racks 11 slide in this direction, thereby pushing the two rotating shafts 9 to rotate in opposite directions, so that the cover plate 2 rotates in the same direction and the cover plate 2 is closed. Of course, the sliding structure may also be two racks 11, which will not be described in detail here. The sliding drive mechanism may include a driving rack 14, a motor 15 and a driving gear 16.

When the sensor senses that the tension between the sliding block 13 and the driving rack 14 is greater than a preset standard force, the controller controls the motor 15 to stop driving. The specific values ​​are not described here. The charging port is closed by two cover plates 2, which has good sealing, convenient operation and high safety. Example

[0033] The installation tube 3 is provided with a sealing ring structure, which is located between the cover plate 2 and the vehicle body panel 1, thereby increasing the sealing performance of the vehicle body panel 1 and the cover plate 2, and can block the gap between the cover plate 2 and the vehicle body panel 1, preventing rainwater or debris from entering the installation tube 3 and causing pollution. The sealing ring structure can be an annular rubber ring, which has good sealing performance, but is easy to cause obstruction during use. The sealing ring structure can also include a sliding track 7, a sealing member 8 and an electromagnet.

When the controller controls the cover plate 2 to open, the controller controls the electromagnets between the sealing member 8 and the sliding track 7 to have different magnetic properties and attract each other, so that the sealing member 8 slides outward, thereby increasing the charging operation space. When the controller controls the cover plate 2 to be closed, the controller controls the sealing member 8 and the electromagnet between the slide rail 7 to have the same magnetic properties, and repel each other to make the sealing member 8 slide inward and close together, thereby improving the sealing performance. Of course, the sealing member 8 can also be a fan-shaped piece, and the sealing member 8 can be close together to form a circular sheet structure, so that the cover plate 2 can be completely covered, thereby improving the sealing performance and aesthetics.
