Description

Technical Field

[0001] The invention relates to the technical field of automobiles, and in particular to an inner sliding hidden charging port cover or a fuel filler port cover. Background Art

[0002] At present, the covers of traditional models are all opened outwards, which takes up a lot of external space and easily interferes with the refueling and charging guns, which has an adverse impact on the future development of intelligent refueling and charging. When the cover is opened outwards, it blocks the field of vision, affects the refueling or charging process, and affects the overall appearance of the car body; Figure 1 As shown in the figure, the appearance diagram of the cover when it is opened outward affects the overall appearance of the vehicle body and the user's field of vision, causing interference with refueling or charging; Figure 2 As shown in the figure, the relationship between the opening cover and the charging gun position is a schematic diagram. When the cover is protruding, it needs to occupy external space, which affects the automatic operation trajectory of refueling and charging gun, and increases the difficulty of the charging gun to identify the surrounding environment. The traditional actuator adopts flat gear transmission. To obtain the same transmission ratio, more gear transmission stages and larger actuator space are required. Ordinary flat gear transmission is intermittent meshing, and the high-speed stage is prone to collision and high noise. The traditional actuator position positioning is set at the motor end with low precision. The traditional clutch structure is complex. Summary of the invention

[0051] The beneficial effects of the present invention are:

[0052] 1. Driven by the actuator assembly, the cover moves along a specific trajectory. To prevent the cover from interfering with the outer sheet metal of the vehicle body, the cover first sinks for a certain distance from the body sheet metal, and then slides inward to the inner side of the sheet metal until the fuel inlet and charging port are completely exposed, without any protrusions on the outside, so as to maintain the overall beauty of the vehicle body appearance. There are no protrusions when inserting the fuel gun and charging gun, which reduces the difficulty of automatic insertion of the fuel gun and electric gun, and simplifies the logic recognition program of the fuel gun and electric gun;

[0053] 2. Reduce the volume of the actuator assembly under the same transmission ratio to leave more space inside the vehicle body; reduce the number of gear transmission stages, reduce product development costs, reduce product production raw materials, and production and assembly costs; improve actuator noise and enhance user comfort; accurately identify the output position of the actuator end, and then accurately judge the opening, operation, and closing process of the cover, provide this position signal to the vehicle, and more accurately control the operation of the cover;

[0054] 3. Simplify the clutch structure, reduce the internal space of the product, and reduce product development costs, raw material costs, and assembly costs;

[0055] 4. The double-stage worm gear transmission is adopted to increase the transmission ratio. Compared with the flat gear transmission with the same transmission ratio, it has fewer transmission stages, simpler structure and smaller actuator volume. The worm gear transmission is continuous meshing in and out, with smooth transmission and low noise. It can improve the interior space of the vehicle body and enhance the comfort of users' vehicles.

[0056] 5. The traditional actuator position control signal is set at the motor end. Because the gears are multi-stage transmission, there is a tooth side clearance between the gears, plus the gear processing and installation errors, when it is transmitted to the output end, the side clearance plus various accumulated errors will cause a large position error when it is transmitted to the output end of the actuator. In order to improve the accuracy of the actuator position recognition, the position sensor is set at the output end of the actuator, which is not affected by the side clearance between the front multi-stage gears and the processing and installation errors, greatly improving the accuracy of the actuator end position recognition, more accurately judging the position of the cover opening, operation, and closing process, and accurately providing the position signal to the vehicle control unit, and accurately controlling the operation of the cover.

[0057] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
