Description

Technical Field

[0001] The utility model belongs to the technical field of automobiles, and in particular relates to a rotating shaft for a charging port cover small door and a charging port cover. Background Art

[0002] As people pay more attention to environmental protection, the continuous development of new energy vehicles has also made it better integrated into people's daily lives. At present, the automatic charging port covers of new energy vehicles on the market are upgraded and evolved on the basis of the traditional fuel tank covers of fuel vehicles. The automatic charging port covers can be opened in various ways, such as button opening, central control screen opening, mobile phone APP opening, charging gun approaching opening, etc., giving users a better sensory experience. In either case, the small door of the charging port cover needs to be driven by the rotation of the rotating shaft to open and close the small door. The small door of the charging port cover on the market first used a plastic rotating shaft. It was found that when the electric vehicle was charging, the charging port was opened. Under manual force operation, the plastic rotating shaft broke, causing the charging port to lose its function. As a result, metal rotating shafts appeared on the market, and this type of rotating shaft was made of powder metallurgy. Although it solved the problem of rotating shaft fracture, it was not only heavy but also costly. Utility Model Content

[0005] The rotating shaft for the charging port cover door includes a metal shaft and a plastic shaft body. The metal shaft and the plastic shaft body are formed by insert injection molding, and the metal shaft is cylindrical.

[0006] Preferably, the plastic shaft body includes a spline section connected to the actuator and a connecting section connected to the small door of the charging port cover.

[0007] Preferably, the metal is SUS304, and the plastic is PA6-GF50.

[0008] Preferably, a spacer is provided between the spline section and the connecting section, and the diameter of the spacer is larger than the outer diameter of the connection point of the rotating shaft of the small door of the charging port cover.

[0009] Preferably, a group of strip-shaped protrusions are symmetrically arranged on the connecting section for matching with the connecting hole of the rotating shaft of the small door of the charging port cover.

[0010] Preferably, a charging port cover using any one of the above-mentioned rotating shafts for the charging port cover door comprises a charging port body, and a charging port cover pivotally arranged above the charging port body, and the other end of the rotating shaft is connected to the actuator via a spline.

[0011] The beneficial effects of the utility model are embodied in that the rotating shaft in the utility model combines metal and plastic by means of insert injection molding, thereby reducing the overall weight of the product, while also improving the rigidity of the product, greatly extending the service life of the product, and having strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following Figure 1-Figure 3 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0017] The utility model proposes a rotating shaft for a charging port cover door, comprising a metal shaft and a plastic shaft body. The metal shaft and the plastic shaft body are formed by insert injection molding. In this embodiment, the metal is SUS304 and the plastic is PA6-GF50. Of course, the specific material can also be replaced by other materials, which is not limited here.

[0018] The metal shaft is cylindrical, and the plastic shaft includes a spline section 41 connected to the actuator and a connecting section 42 connected to the charging port cover small door. A spacer 43 is provided between the spline section 41 and the connecting section, and the diameter of the spacer 43 is larger than the outer diameter of the connection of the charging port cover small door shaft. A group of bar-shaped protrusions 44 are symmetrically provided on the connecting section 42 for matching with the connecting hole of the charging port cover small door shaft.

[0019] Combination Figure 2-Figure 3 As shown, the charging port cover generally includes a charging port body 2 and a charging port cover small door 1 connected to the charging port body 2 through a rotating shaft. An actuator 3 is also provided on the side of the charging port cover small door 1. The actuator is connected to the rotating shaft to drive the rotating shaft to rotate, thereby driving the charging port cover small door 1 to open or close the charging port cover body 2. The above specific driving method and the relationship between the charging port body 2, the small door and the actuator are the same as the prior art, and are not the focus of this protection, so they are not repeated here.

[0020] When the above-mentioned rotating shaft for the charging port cover small door is specifically applied to the charging port cover, the rotating shaft 4 is inserted into the connecting hole to be inserted into the charging port cover small door 1, and its spacer 43 abuts against the end of the connecting hole, so that the spline segment 41 protrudes from the connecting hole, and the spacer 43 also plays a role of limiting. The protruding spline segment 41 will be connected to the actuator on one side.

[0021] Finally, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
