Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a novel automotive refueling and charging port box structure. Background Technology

[0002] With the development of the automotive industry, the functionality and convenience of vehicles are receiving increasing attention. The fuel filler cap or charging port cover for new energy vehicles, as a frequently opened and closed component, directly impacts the user experience due to its structural reliability and durability. Currently, most common flip-up cap covers on the market use hinges made entirely of plastic to connect to the cap body.

[0003] However, these pure plastic hinges have inherent defects. First, the outer panel (i.e., the hinge cover) itself has a certain weight. During long-term vehicle use, this gravity will continuously act on the hinge's pivot connection. Under long-term stress, the plastic material is prone to creep, causing the hinge to stretch or deform. Second, for automated hinges driven by motors, the actuator generates a large torque at the moment of start-up and stop. Repeated impacts will also accelerate the aging and fatigue of the plastic hinge, and in severe cases, may even lead to hinge breakage. These deformations or damages will ultimately lead to uneven clearance between the outer panel and the vehicle body, abnormal noises, unsmooth opening and closing, or even failure to close properly, seriously affecting the product's quality and reliability. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of automotive refueling and charging port box structure to address the shortcomings of the existing technology.

[0005] The specific technical solution is as follows:

[0006] A novel automotive refueling and charging port box structure includes:

[0007] A mouth box, wherein the mouth box is provided with a cavity, at least one shaft hole and a fixing structure;

[0008] An actuator, which is detachably fixed to the fixing structure of the mouth box and can realize electrically controlled forward and reverse rotation;

[0009] A rotating shaft, which is connected to the actuator in a driving manner;

[0010] A hinge, movably connected to the housing via the pivot, for rotation about the pivot hole of the housing, wherein the rotating portion of the hinge contains a plastic-coated metal insert; and

[0011] The outer panel is fixed to the hinge and moves synchronously with the hinge.

[0012] Optionally, the hinge is installed in the cavity, the mouth box has two concentric shaft holes, and the hinge also has two concentric shaft holes corresponding to the shaft holes of the mouth box.

[0013] Optionally, the rotating shaft has at least two concentric cylindrical portions, and the rotating shaft passes through its cylindrical portions into the shaft hole of the mouth box and the shaft hole of the hinge, thereby enabling the hinge to rotate around the shaft hole of the mouth box.

[0014] Optionally, the hinge is provided with a keyway, and the rotating shaft is provided with a boss that mates with the keyway. The boss of the rotating shaft and the keyway of the hinge are connected by an interference fit so that the rotating shaft and the hinge rotate synchronously.

[0015] Optionally, the outer panel and the hinge are fixedly connected by a mutually cooperating snap-fit ​​structure.

[0016] Optionally, the fixing structure of the mouth box is a screw fixing post, and the actuator is fixed to the screw fixing post by screws; a pin is provided on the rotating shaft, and the output end of the actuator is provided with a keyway that cooperates with the pin to transmit the power of the actuator to the rotating shaft.

[0017] Optionally, the actuator drives the hinge to rotate via the rotating shaft, and the hinge in turn drives the outer plate to rotate synchronously, so as to realize the opening and closing of the box structure.

[0018] Optionally, the rotating part of the hinge is a U-shaped structure, and the metal insert is disposed inside the U-shaped structure.

[0019] Optionally, the metal insert is provided with a shaft hole coaxial with the shaft hole of the hinge.

[0020] Optionally, the metal insert is completely covered by the plastic material of the hinge, so that the metal insert does not come into direct contact with the outside world.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This invention incorporates metal inserts into key stress-bearing parts of the hinge (the U-shaped rotating part and the shaft hole). Utilizing the superior rigidity and strength of the metal material, it effectively resists creep deformation caused by the long-term weight of the outer plate, as well as the impact torque generated during actuator start / stop, fundamentally preventing hinge stretching, deformation, and even breakage. The metal inserts are completely encased in plastic and integrally molded using an insert injection molding process. This ensures that the hinge's appearance and key mating dimensions are entirely guaranteed by the mold, unaffected by the internal metal inserts. This guarantees the precision of the fit with components such as the housing and rotating shaft, ensuring smooth movement and long-term stability. Furthermore, due to the presence of the metal inserts, the hinge will not fail due to corrosion (protected by the plastic) or fatigue. The reliability of the entire opening and closing mechanism is significantly improved. Long-term structural stability translates to a longer service life, reducing maintenance costs and user complaints caused by housing failures, and enhancing the overall quality of the vehicle.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0031] This utility model provides a novel automotive refueling and charging port box structure, referring to... Figures 1-4 ,include:

[0032] The mouth box 2 has a cavity 2a, at least one shaft hole and a fixing structure;

[0033] Actuator 5 is detachably fixed to the fixed structure of the housing 2 and can realize electrically controlled forward and reverse rotation;

[0034] Rotating shaft 4 is connected to actuator 5 via a transmission.

[0035] Hinge 3 is movably connected to the housing 2 via a pivot 4, rotating around the pivot hole of the housing 2. The rotating part of hinge 3 contains a plastic-metal insert 3e.

[0036] Outer plate 1 is fixed to hinge 3 and moves synchronously with hinge 3.

[0037] like Figure 1 As shown, the housing 2 is the basic component of the entire structure. It has a cavity 2a for accommodating the hinge 3 and other moving parts. In order to realize the rotational installation of the hinge 3, the housing 2 has two concentric first shaft holes 2b and second shaft holes 2c as the reference for rotational movement. In addition, the housing 2 also has an integrally formed screw fixing post 2d, which serves as the mounting base for the actuator 5.

[0038] like Figures 1-2 As shown, hinge 3 is a key component connecting outer plate 1 and opening / closing box 2. To cooperate with the first shaft hole 2b and second shaft hole 2c of opening box 2, hinge 3 is provided with two concentric third shaft holes 3a and fourth shaft holes 3b. Rotating shaft 4 serves as a connecting pivot, with its two concentrically positioned first cylinder 4a and second cylinder 4b passing sequentially through the first shaft hole 2b and second shaft hole 2c of opening box 2, and the third shaft hole 3a and fourth shaft hole 3b of hinge 3. This allows hinge 3 to be rotatably mounted within the cavity 2a of opening box 2, enabling hinge 3 to rotate precisely around the central axis determined by the first shaft hole 2b and second shaft hole 2c.

[0039] To achieve power transmission, this embodiment employs a synchronous motion mechanism. Specifically, as follows: Figure 2As shown, a boss 4c is provided on the rotating shaft 4, and a keyway 3c is provided at the corresponding position on the hinge 3. During assembly, the boss 4c of the rotating shaft 4 is inserted into the keyway 3c of the hinge 3 in an interference fit manner. This interference fit ensures that there is no relative rotation between the two. When the rotating shaft 4 rotates, its torque can be transmitted to the hinge 3 without loss, thereby driving the hinge 3 to achieve synchronous rotation.

[0040] The outer panel 1, which is the cover directly visible to the user, is fixedly connected to the hinge 3 via a snap-fit ​​structure. Specifically, the outer panel 1 has several snaps 1a, and the hinge 3 has corresponding snaps 3d. During assembly, the snaps 1a of the outer panel 1 are aligned and pressed into the snaps 3d of the hinge 3, achieving a quick and secure connection. Since the outer panel 1 is fixed to the hinge 3, the movement of the hinge 3 is transmitted to the outer panel 1 in a completely synchronized manner.

[0041] like Figure 2 As shown, the power source of this structure is actuator 5, typically a small DC motor. Actuator 5 is secured to the screw fixing post 2d of the housing 2 by screws 6 passing through its own screw hole 5a, achieving a stable installation. The power output end of actuator 5 has a keyway 5b, while the corresponding end of the rotating shaft 4 has a pin 4d. The keyway 5b of actuator 5 fits onto the pin 4d of rotating shaft 4, forming a transmission connection. When actuator 5 is energized, its output shaft rotates, driving rotating shaft 4 to rotate synchronously through the cooperation of keyway 5b and pin 4d. This forms a complete kinematic chain: the rotation of actuator 5 drives rotating shaft 4, the rotation of rotating shaft 4 drives hinge 3, and the rotation of hinge 3 drives outer plate 1, thereby realizing the electric opening and closing of the housing cover.

[0042] See Figure 2 and Figure 3 Inside the hinge 3, particularly in the U-shaped rotating portion where it bears the main stress, a metal insert 3e is embedded. This metal insert 3e is preferably made of a high-strength metal material such as steel or aluminum alloy. Figure 4As shown, the shape of the metal insert 3e matches the internal contour of the hinge 3, and it also has a fifth shaft hole 3e-a and a sixth shaft hole 3e-b that are completely coaxial with the third shaft hole 3a and the fourth shaft hole 3b of the hinge 3. During manufacturing, this metal insert 3e is pre-placed in an injection mold, and then plastic (such as PA, PBT, and other engineering plastics) is injection molded, completely encapsulating the metal insert 3e to form a "plastic-coated metal insert" structure. The metal insert 3e is completely encapsulated by plastic and does not come into contact with the outside environment, effectively preventing corrosion. Simultaneously, due to the presence of the metal insert 3e, the overall rigidity and strength of the hinge 3 are greatly improved, effectively resisting the gravity of the outer plate 1 and the torque of the actuator 5 without deformation or breakage. The external dimensions of the hinge 3 are entirely guaranteed by a precision mold, ensuring its precision in fitting with other components. This "strong inside, precise outside" design fundamentally solves the problems mentioned in the background art.

[0043] In summary, this utility model, by cleverly setting a plastic-coated metal insert 3e in the hinge 3 and cooperating with a precise electromechanical linkage design, successfully creates a robust, reliable, and long-lasting automotive refueling and charging port box structure.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
