[0052] To address the technical problems of existing charging port door structures being simple, low-strength, and occupying a large external space, thus affecting the overall aesthetics of the vehicle, this disclosure provides an opening and closing structure for an automotive charging port door, including a cover assembly 1, a drive mechanism, and a guide rail assembly 5, such as... Figure 1 As shown, the drive mechanism includes:

[0053] Actuators (not shown in the diagram) are used to provide driving force, such as motors, motor controllers, reducers, and other devices;

[0054] The first drive slider 4 and the second drive slider 16 are respectively connected to the two sides of the cover assembly 1, and the first drive slider 4 and the second drive slider 16 can slide on the guide rail assembly.

[0055] The first cable 10 and the second cable 11 are connected at both ends to the first drive slider 4 and the second drive slider 16 respectively through the first fixed pulley group. The two ends of the second cable 11 are connected to the first drive slider 4 and the second drive slider 16 respectively through the second fixed pulley group. That is, each cable needs to be fixedly connected to the drive sliders on both sides. The two cables pull the drive slider to slide in the guide rail.

[0056] The winding wheel 9 is connected to an actuator (e.g., a drive shaft connected to a motor) to drive the first cable 10 and the second cable 11 by the driving force provided by the actuator. The first cable 10 and the second cable 11 drive the first drive slider 4 and the second drive slider 16 to slide on the guide rail assembly 5, thereby opening or closing the cover assembly 1.

[0057] With the above technical solution, when the motor rotates clockwise, the first cable 10 and the second cable 11 drive the first drive slider 4 and the second drive slider 16 to move from the second end to the first end of the guide rail assembly 5 until they reach the fully open position. When the motor rotates counterclockwise, the first cable 10 and the second cable 11 drive the first drive slider 4 and the second drive slider 16 to move from the first end to the second end of the guide rail assembly 5, completing the closing action.

[0058] Compared to conventional charging port door opening and closing structures, which often occupy a large space and have an unsightly appearance when open, this invention utilizes a combination of cables, fixed pulleys, and movable pulleys to drive the cover inward (i.e., to open it by moving it towards the interior of the vehicle body), further reducing the space occupied by the charging port door assembly. The cover assembly is concealed within the vehicle body after opening, improving the overall consistency of the vehicle's appearance. Furthermore, this invention employs a dual-side drive system, which offers higher stability (and superior dust resistance and durability) compared to existing single-side drive structures. This simple structure further enhances the lightweight design of the charging port door and allows for the integration of other electrical components such as lights and power displays, resulting in a more technologically advanced and intelligent feel, making the overall vehicle appearance more aesthetically pleasing and clean, and enhancing its technological appeal.

[0059] As an optional implementation method, such as Figure 1 As shown, the first and second fixed pulley groups are used to change the direction of tension of the first cable 10 and the second cable 11, respectively. The guide rail assembly 5 includes a first guide rail 51 and a second guide rail 52. The first drive slider 4 can slide on the first guide rail 51, and the second drive slider 16 can slide on the second guide rail 52.

[0060] The first fixed pulley system includes:

[0061] The first fixed pulley 8 is located at the first end of the first guide rail 51 and can be located on the outside of the first guide rail 51.

[0062] The second fixed pulley 3 is disposed at the second end of the first guide rail 51;

[0063] The third fixed pulley 13 is disposed at the first end of the second guide rail 52;

[0064] The first end of the first cable 10 passes over the first fixed pulley 8 and the second fixed pulley 3, and is fixed to the second end of the first drive slider 4 (in this embodiment). Figure 1 As shown, the second end of the first cable 10 passes over the third fixed pulley 13 and is fixed to the first end of the second drive slider 16 (the end near the third fixed pulley 13). In this embodiment, the first end of the first cable 10 and the rear end of the first drive slider 4 are fixedly connected, and the second end of the first cable 10 and the front end of the second drive slider 16 are fixedly connected.

[0065] The second fixed pulley system includes:

[0066] The fourth fixed pulley 12 is located at the first end of the second guide rail 51 and can be located on the outside of the second guide rail 52.

[0067] The fifth fixed pulley 17 is located at the second end of the second guide rail 52;

[0068] The sixth fixed pulley 7 is located at the first end of the first guide rail 51 and can be located inside the first guide rail 51.

[0069] The first end of the second cable 11 passes over the fourth fixed pulley 12 and the fifth fixed pulley 17 and is fixed to the second end of the second drive slider 16. The second end of the second cable 11 passes over the sixth fixed pulley 7 and is fixed to the first end of the first drive slider 4. In this embodiment, the first end of the second cable 11 and the rear end of the second drive slider 16 are fixedly connected, and the second end of the second cable 11 and the front end of the first drive slider 4 are fixedly connected.

[0070] For example, such as Figure 1 As shown, in this embodiment, a cable is used as a transmission component to transmit the tension output by the motor. Cables 10 and 11 are wound around the winding wheel 9, with reserved installation lengths on both sides. The reserved left end of cable 10 passes over fixed pulleys 8 and 3 and is fixed to the rear end of the drive slider 4 on the left guide rail. The reserved right end of cable 10 passes over fixed pulley 13 and is fixed to the front end of the drive slider 16 on the right guide rail. The reserved left end of cable 11 passes over fixed pulley 7 and is fixed to the front end of the left drive slider 4. The reserved right end of cable 11 passes over fixed pulleys 12 and 17 and is fixed to the rear end of the right drive slider 16. This achieves the control of the forward and backward movement of the left drive slider 4 through the reserved left ends of cable 10 and cable 11, and the same applies to the right side.

[0071] When the motor rotates clockwise, the left side of cable 10 tightens, while the left side of cable 11 extends, the right side of cable 10 extends, and the right side of cable 11 tightens. This controls the first drive slider 4 and the second drive slider 16 to move towards the winding wheel 9, completing the opening action. Similarly, when the motor rotates counterclockwise, it moves in the opposite direction to the cable, completing the closing action. In this embodiment, by using a combination of pulleys and cables, the internal space is effectively compressed to a more compact size due to the characteristics of the pulley system. Therefore, compared to other concealed charging port covers on the market, the length is shortened by 30mm-50mm.

[0072] As an optional implementation method, such as Figure 1 As shown, the opening and closing structure also includes:

[0073] The first pulley adjustment device 14 is installed on the third fixed pulley 13 and is used to adjust the position of the third fixed pulley 13, thereby adjusting the preload of the first cable 10.

[0074] The second pulley adjustment device 6 is installed on the sixth fixed pulley 7 and is used to adjust the position of the sixth fixed pulley 7, thereby adjusting the preload of the second cable 11.

[0075] Because the actual length of the cable can vary vertically due to production issues, this embodiment employs a pulley adjustment device to improve the pulley's tolerance. If the cable length deviates downwards, the spring is compressed; if the cable is at its upper limit, the spring extends, and then the pulley is fixed. This ensures that the cable preload does not change with length variations, thereby improving the stability of the cable drive.

[0076] As an optional implementation method, such as Figure 1 As shown, the cover assembly 1 includes:

[0077] The outer cover plate 101 and the inner cover plate 102 are fixedly connected by a snap-fit ​​structure.

[0078] like Figure 3 As shown, the first cover plate groove 103 is disposed on one side of the inner plate 102 of the cover corresponding to the first guide rail 51, as follows: Figure 6 As shown, the first support arm of the first drive slider 4 (the support arm structure is as follows) Figure 4 As shown in 401), it can slide within the first cover plate groove 103, such as Figure 8 As shown, the main body of the first drive slider 4 can slide on the first guide rail 51 of the guide rail assembly 5;

[0079] The first cover plate sliding foot 104 and the second cover plate sliding foot 105 are disposed on one side of the inner plate 102 of the cover corresponding to the first guide rail 51, and the first cover plate sliding foot 104 and the second cover plate sliding foot 105 can slide on the first guide rail 51.

[0080] Similarly, the second cover plate groove is provided on one side of the inner plate 102 of the cover corresponding to the second guide rail 52. The second support arm of the second drive slider 16 can slide in the second cover plate groove, and the main body of the second drive slider 16 can slide on the second guide rail 52 of the guide rail assembly 5, so that the first drive slider 4 and the cover assembly 1 are driven to slide through the second drive slider 16.

[0081] The third and fourth cover plate sliding feet are located on one side of the inner cover plate 102 corresponding to the second guide rail 52, and can slide on the second guide rail 52. The second cover plate groove has the same structure as the first cover plate groove 103 on the left side of the inner cover plate 102 and is symmetrically arranged. The third and fourth cover plate sliding feet have the same structure as the first cover plate sliding foot 104 and the second cover plate sliding foot 105 on the left side of the inner cover plate 102 and are symmetrically arranged. These will not be described in detail below.

[0082] Specifically, such as Figure 5As shown, both the first cover plate groove 103 and the second cover plate groove are arc-shaped, with points C and D at their ends having different heights. The function of the drive slider is to provide sliding force for the movement of the cover assembly 1. When the cover assembly 1 is open, the drive slider is driven by a cable. The support arm 401 of the first drive slider 4 moves from point D to point C in the first cover plate groove 103 to complete the downward movement. At the same time, the support arm of the second drive slider 16 moves from point D to point C in the second cover plate groove to complete the downward movement. This causes the cover assembly 1 to tilt downward at an angle, allowing it to slide along the guide rail into the vehicle body, achieving a hidden opening. After opening, the cover assembly is hidden inside the vehicle body and not exposed outside, which enhances the technological feel of the car and improves the user experience. When the cover assembly 1 is closed, the drive slider is driven by a cable. The support arm of the drive slider moves from point C to point D in the two cover plate grooves to complete the lifting movement, lifting until it is flush with the surface of the vehicle body, thus completing the closing action.

[0083] To address the issue of low strength in traditional charging door opening and closing structures, this embodiment employs a dual-sided drive system with three sliding feet on each side, resulting in uniform force distribution and high structural strength. Traditional structures are exposed when open, making the rocker arm prone to breakage from impacts by unintended hard objects. The opening and closing structure of this invention, however, boasts higher strength and is less susceptible to damage from external objects while operating within the vehicle. Furthermore, the sliding groove structure enables the cover assembly to achieve a self-locking function when closed.

[0084] This disclosure also provides an electric vehicle, including the opening and closing structure of the vehicle charging port door described in any of the above embodiments. Compared with the charging door opening and closing structure, which has the problems of large space occupation and unsightly appearance after opening, this disclosure achieves the internal movement of the charging port cover assembly by using a combination of cable, fixed pulley, and movable pulley for drive and guide rail running groove to restrict the movement, further reducing the size of the space. After opening, the cover is hidden in the vehicle body, improving the consistency of the overall vehicle appearance. In addition, this disclosure adopts a dual-side drive method, which has higher stability compared with the existing single-side drive structure. This structure is simple, which helps to reduce the overall vehicle cost and can further improve the lightweight level of the charging port door. It can also integrate other electrical components such as lights and power display, giving it a strong sense of technology and intelligence, making the overall vehicle appearance more beautiful and neat, and enhancing the technological feel of the vehicle.

[0085] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
