Description

Technical Field

[0001] This application relates to, but is not limited to, the field of vehicle parts, and particularly to a cover assembly and a vehicle. Background Technology

[0002] The charging port assembly is an essential unit in the vehicle, providing an operating channel for charging or refueling while protecting the charging or refueling port. Traditional charging ports mainly consist of an outer cover and an internal structure, which are connected by snap-fit ​​or screw connections. The internal structure mainly includes an opening mechanism and a rotating arm that connects to the outer cover.

[0003] Currently, the relevant technology has significant limitations: First, the gap and surface difference between the outer cover of the traditional cover and the side panel of the vehicle body cannot be effectively adjusted. During the vehicle assembly process, to achieve ideal assembly precision, it is often necessary to repeatedly modify the outer cover mold, adjusting the surface dimensions of the outer cover to match the gap and surface difference. This adjustment method has many drawbacks: on the one hand, it requires collecting a large amount of actual vehicle data as a basis for mold modification, resulting in an excessively long mold modification cycle; on the other hand, it is difficult to respond promptly to the adjustment needs during the actual vehicle assembly process, seriously affecting the overall appearance refinement of the vehicle. Furthermore, this adjustment method relying on mold modification carries high quality risks and economic losses. Each mold modification may lead to the scrapping of already produced parts due to dimensional changes, causing serious resource waste. At the same time, the repeated mold modification process requires a large investment of manpower and resources, significantly increasing production costs.

[0004] Therefore, there is an urgent need for a cover assembly and vehicle that can adjust the gap between the outer cover and the side panel in real time, improve the overall refinement of the vehicle, and at the same time avoid the risk of multiple mold repairs and parts scrapping, saving manpower and material costs.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0048] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0049] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design.

[0050] For ease of description, we define the X direction as the first direction, the Y direction as the second direction, and the Z direction as the third direction.

[0051] This application provides a vehicle, including a vehicle body, which is the basic frame for mounting and connecting other vehicle components. The vehicle body has a charging port and / or a refueling port.

[0052] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. Generally, a vehicle is equipped with wheels, a power source, and a transmission system between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, causing the wheels to rotate and thus driving the vehicle.

[0053] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.

[0054] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The vehicle provided in this application embodiment, in addition to the vehicle body described above, also includes a cover assembly. The cover assembly includes a housing, a connecting plate 8, a base 3, an outer cover 1, a gap adjustment assembly, and a surface difference adjustment assembly. The housing is installed on the side of the vehicle body to provide a stable mounting base for the cover assembly. The connecting plate 8 is rotatably disposed on the housing, thereby forming a neck structure for an openable and closable fuel filler port and / or charging port. The connecting plate 8 is rotatably connected to the housing via a pivot or bearing structure, specifically a hinge or pivot structure, to support the outer cover 1 and achieve its angle adjustment relative to the vehicle body.

[0055] The base 3 is fixedly connected to the connecting plate 8. The outer cover 1 is located on the outside of the connecting plate 8. The gap adjustment component is used to adjust the position of the outer cover 1 relative to the connecting plate 8 in the first direction and / or the second direction. The surface difference adjustment component is used to adjust the gap between the outer cover 1 and the connecting plate 8 in the third direction.

[0056] Specifically, the gap adjustment assembly includes a gap adjustment member 5, which is disposed on the base 3 along a first direction and / or a second direction. The gap adjustment member 5 rotates along the first direction and / or the second direction and synchronously drives the outer cover 1 to rotate.

[0057] The surface difference adjustment assembly includes a surface difference adjustment component 4, which is movably disposed on the connecting plate 8 along a third direction and drives the outer cover 1 to move synchronously.

[0058] Compared with related technologies, the position of the outer cover 1 in a traditional cap assembly is entirely determined by the mold, and any assembly error requires mold rework. This application integrates a gap adjustment component and a surface difference adjustment component inside the cap assembly, enabling the outer cover 1 to be adjusted along a first direction, a second direction, and a third direction. Assembly workers can directly complete the gap and surface difference adjustment on the final assembly line without waiting for mold modification.

[0059] Through the above technical solution, this application realizes three-way adjustment of the outer cover 1 position, effectively eliminating the assembly mismatch problem caused by the accumulation of body tolerances, enabling the cover assembly to have the ability to adapt and adjust, while maintaining the appearance refinement, significantly reducing the dependence on mold precision, and avoiding the scrapping of parts and production interruption caused by mold repair.

[0060] Reference Figure 4 , Figure 5 , Figure 6 In some embodiments of this application, a gap limiting groove 33 is provided on the base 3 along the first direction and / or the second direction, and the gap adjusting member 5 is slidably disposed in the corresponding gap limiting groove 33.

[0061] The gap limiting groove 33 is a guide structure set along a specific direction of the base 3, which can be implemented as an elongated groove, used to constrain the movement trajectory of the gap adjusting component 5. The gap adjusting component 5 is slidably set in the corresponding gap limiting groove 33, and the stability of the position adjustment is achieved through sliding friction.

[0062] The gap adjusting member 5 and the gap limiting groove 33 are in a one-to-one cooperation relationship. At least one gap adjusting member 5 is provided. In some embodiments, two gap adjusting members 5 are provided. The gap limiting groove 33 is opened on the base 3 along the first direction and the second direction. Correspondingly, the two gap adjusting members 5 are respectively arranged in the corresponding gap limiting groove 33 along the first direction and the second direction.

[0063] Specifically, when it is necessary to adjust the gap between the outer cover 1 and the side panel, the gap adjusting member 5 slides in the corresponding gap limiting groove 33 along the first or second direction. Due to the guiding effect of the gap limiting groove 33, the movement trajectory of the adjusting member is restricted, thereby causing the outer cover 1 to deflect at an angle in the first or second direction, thus changing the relative position between the edge of the outer cover 1 and the side panel, realizing the adjustment of the gap size. During the adjustment process, the gap limiting groove 33 can ensure that the gap adjusting member 5 makes the expected displacement, ensuring the adjustment accuracy.

[0064] Compared to related technologies, traditional solutions rely on mold modification to change the surface dimensions of the outer cover 1. This application, however, utilizes a mating structure between the gap limiting groove 33 and the gap adjusting component 5, allowing operators to adjust the position of the outer cover 1 along a first and / or second direction during the assembly stage. This adjustable structure replaces the traditional mold modification process, avoiding production interruptions caused by repeated mold modifications and eliminating the risk of batch scrapping of parts due to improper mold modifications.

[0065] Through the above technical solution, this application realizes the online adjustable function of the gap of the outer cover 1. During the assembly process, the gap matching can be completed directly by the sliding operation of the adjusting part. This structure effectively solves the problems of long mold modification cycle and high part scrap rate in the traditional solution, improves assembly efficiency and reduces production cost, while ensuring the consistency of the gap between the outer cover 1 and the side wall.

[0066] Reference Figure 4 , Figure 6 , Figure 7 , Figure 8 In some embodiments of this application, the gap adjustment assembly further includes a gap pin 6, which is movably disposed on the connecting plate 8 along a third direction. The gap pin 6 includes a pin body 63 and a convex ring 64 coaxially disposed on the pin body 63. A gap adjustment groove 52 is provided on the gap adjustment member 5, and the convex ring 64 is connected to the gap adjustment groove 52. The gap pin 6 has a gap adjustment hole 61 located on the inner side of the connecting plate 8. The gap adjustment hole 61 can be manipulated to drive the gap pin 6 to rotate and synchronously drive the gap adjustment member 5 to rotate.

[0067] Among them, the convex ring 64 is an annular protrusion structure coaxially set on the pin body 63, which can be realized by injection molding or machining, and is used to form a sliding fit with the clearance adjustment groove 52.

[0068] Specifically, when the operating tool is inserted into the gap adjustment hole 61 and a rotational force is applied, the gap pin 6 rotates around its own axis, and its convex ring 64 slides in the gap adjustment groove 52, transmitting the rotational motion to the gap adjustment component 5. Since the gap adjustment component 5 and the base 3 are connected by a sliding constraint through the gap limiting groove 33, the rotation of the gap adjustment component 5 will be converted into the displacement of the outer cover 1 along the first direction or the second direction, thereby achieving precise adjustment of the gap between the outer cover 1 and the side wall.

[0069] In some embodiments, a friction assembly may be provided between the convex ring 64 and the gap adjustment groove 52 to increase friction, such as a gear or to increase the coefficient of friction of the contact surfaces of the two.

[0070] Compared with related technologies, traditional solutions require disassembling the outer cover 1 and adjusting the gap through mold modification. However, this application, through the linkage structure of the gap pin 6 and the gap adjustment component 5, can directly complete the adjustment without disassembling the component, thus avoiding the risk of scrapping parts caused by repeated mold modification.

[0071] Through the above technical solution, this application realizes that the gap of the outer cover 1 is adjustable along the first direction or the second direction. The operator only needs to rotate the gap pin 6 with a standard tool to complete the adjustment, which significantly shortens the assembly and debugging cycle and eliminates the problem of part size deviation caused by repeated mold modifications.

[0072] Reference Figure 3 , Figure 4 In some embodiments of this application, the outer cover 1 is provided with a gap guide groove 11, and a spring 7 is provided between the gap adjusting member 5 and the gap guide groove 11. The spring 7 is used to apply a preload to the gap adjusting member 5 so that the gap adjusting member 5 abuts against the convex ring 64. The gap guide groove 11 has a spring sliding limiting surface 111. One end of the spring 7 is connected to the spring sliding limiting surface 111, and the other end is connected to the gap adjusting member 5.

[0073] The gap guide groove 11 is a linear guide structure formed on the surface of the outer cover 1, which is used to limit the movement path of the gap adjustment member 5 and maintain the stability of the movement.

[0074] Among them, the spring sliding limiting surface 111 is a planar structure set in the gap guide groove 11, which is used to constrain the axial displacement of the spring 7 and provide a mounting point for one end of the spring 7.

[0075] Specifically, when the gap adjusting component 5 rotates, the spring 7 undergoes elastic deformation, and the gap adjusting component 5 slides within the gap guide groove 11, causing a controllable change in the relative position between the gap adjusting component 5 and the outer cover 1. During this process, the preload of the spring 7 keeps the gap adjusting component 5 in close contact with the convex ring 64, ensuring the controllability of the gap adjustment between the outer cover 1 and the side panel.

[0076] Compared with related technologies, traditional solutions rely on mold adjustment to adjust the gap, which requires repeated disassembly of parts and measurement of data. However, this application realizes the gap adjustment along the first direction and / or the second direction during the assembly process through the cooperation of spring 7 and gap guide groove 11, avoiding manual intervention and mold modification.

[0077] Through the above technical solution, this application can improve the controllability of the gap adjustment process between the outer cover 1 and the side wall, reduce the number of manual adjustments, and improve assembly efficiency.

[0078] In some embodiments of this application, the gap adjusting member 5 has a gap adjusting end face 53, the gap guide groove 11 has a gap matching surface 112, and the gap adjusting end face 53 and the gap matching surface 112 are slidably connected.

[0079] Among them, the gap adjustment end face 53 is the end surface of the gap adjustment component 5 that contacts the gap guide groove 11, and the gap matching surface 112 is the contact surface of the gap guide groove 11 that cooperates with the gap adjustment end face 53. The gap adjustment end face 53 contacts the gap matching surface 112 to realize the sliding connection between the gap adjustment component 5 and the outer cover 1.

[0080] Specifically, when the gap adjusting member 5 rotates along the first direction or the second direction, relative sliding occurs between its gap adjusting end face 53 and the gap matching surface 112, forcing the outer cover 1 to shift angularly around the rotation axis. The rotation angle of the gap adjusting member 5 is converted into the linear displacement of the outer cover 1, thereby changing the gap size between the outer cover 1 and the side wall.

[0081] Compared with related technologies, the outer cover 1 of the traditional cap assembly is fixedly connected to the internal structure, and the gap adjustment depends on mold repair. However, this application directly transmits the adjustment action through the gap adjustment end face 53 and the gap matching surface 112, and can realize dynamic gap adjustment without disassembling the outer cover 1, thus avoiding the risk of parts scrapping caused by repeated mold repair.

[0082] Through the above technical solution, this application can directly adjust the gap along the first direction and / or the second direction by means of the gap adjustment component 5 after the outer cover 1 is assembled, eliminate the gap mismatch problem caused by manufacturing error or assembly deviation, improve the assembly accuracy of the cover and the side panel, and reduce the cost of parts rework.

[0083] Reference Figure 4 , Figure 7 , Figure 8 , Figure 9 In some embodiments of this application, a rotating upper shaft 62 and a rotating lower shaft 65 are coaxially arranged on the pin body 63, a rotating groove 34 is provided on the base 3, the rotating lower shaft 65 is rotatably disposed in the rotating groove 34, a rotating hole 81 is provided on the connecting plate 8, and the rotating upper shaft 62 is rotatably connected to the rotating hole 81.

[0084] Among them, the rotating upper shaft 62 is a cylindrical protrusion formed by the axial extension of the top end of the pin 63, and the rotating hole 81 is a through hole opened on the surface of the connecting plate 8, which allows the rotating upper shaft 62 to rotate freely in the rotating hole 81. The rotating upper shaft 62 is inserted into the rotating hole 81 on the connecting plate 8, and the diameter of the rotating upper shaft 62 is the same as the diameter of the rotating hole 81.

[0085] The rotating bottom shaft 65 refers to the cylindrical protrusion formed by the axial extension of the bottom end of the pin 63. The rotating groove 34 is an annular groove on the surface of the base 3, which is used to accommodate the rotating bottom shaft 65 and provide circumferential rotational freedom. The rotating bottom shaft 65 contacts and matches the rotating groove 34 on the base 3, and is used to embed into the rotating groove 34 to achieve axial positioning.

[0086] Specifically, when the gap adjustment hole 61 is driven by the tool, the gap pin 6 rotates around its axis as a whole, the upper rotating shaft 62 rotates circumferentially within the rotating hole 81, and the lower rotating shaft 65 rotates synchronously within the rotating groove 34. This dual-shaft structure forms two rotational fulcrums, ensuring the gap pin 6 maintains axial stability during rotation and preventing skewing caused by unilateral support. The rotating groove 34 axially limits the lower rotating shaft 65, preventing axial movement of the gap pin 6 during rotation and ensuring the transmission accuracy between the gap adjustment component 5 and the outer cover 1.

[0087] This application establishes a coaxial dual-rotation shaft structure to form double support from the top and bottom, effectively suppressing radial offset when the gap pin 6 rotates, improving the stability of gap adjustment, realizing axial and radial dual limiting during the rotation of the gap pin 6, eliminating transmission errors caused by insufficient support, ensuring the accuracy and repeatability of the gap adjustment of the outer cover 1, and reducing the risk of failure of parts due to uneven wear, thus extending service life.

[0088] Reference Figure 3 , Figure 4 , Figure 5 In some embodiments of this application, a fixing member 31 is fixedly provided on the base 3, and the fixing member 31 is fixedly connected to the connecting plate 8.

[0089] The fixing component 31 is set on the base 3 for rigid connection with the connecting plate 8. The fixing component 31 can be a mechanical part such as a bolt or an integrally formed fixing structure, such as a cylinder. Its function is to prevent relative displacement between the base 3 and the connecting plate 8 through rigid connection, so that the gap pin 6 cannot move along the axial direction, but can only rotate around the axial direction, thereby improving the overall structural stability, further ensuring the movement accuracy of the gap adjustment component and the surface difference adjustment component during the adjustment process, avoiding adjustment failure caused by loosening of the base 3 and the connecting plate 8, simplifying the assembly process, and improving the first pass rate of the cover assembly in the actual vehicle assembly.

[0090] Reference Figure 2 , Figure 4 , Figure 7 , Figure 10 In some embodiments of this application, the surface difference adjustment assembly includes a surface difference disk 41 and a rod 42 fixedly disposed on the surface difference disk 41. The rod 42 passes through the base 3 and is threadedly connected to the connecting plate 8. The rod 42 has a surface difference adjustment hole 43 on the inner side of the connecting plate 8 for driving the rod 42 to rotate.

[0091] Among them, the face difference disk 41 is a disk-shaped structure used to provide a face difference adjustment reference. The outer cover 1 is moved by the face difference disk 41 and the adjustment end cover.

[0092] Among them, the rod 42 is a columnar structure that extends coaxially with the surface disc 41. Specifically, it can be implemented in the form of a threaded rod, which converts the rotational motion into axial displacement through a threaded connection.

[0093] Among them, the surface difference adjustment hole 43 is a drive interface set at the end of the rod 42. Specifically, it can adopt a hexagonal hole, cross groove or irregular hole structure, which is used to cooperate with the tool to realize the rotation of the rod 42.

[0094] In some embodiments, the gap adjustment hole 61 can be the same size as the surface difference adjustment hole 43, so that the same set of tools can be used for operation.

[0095] Specifically, the face difference disc 41 forms an axial displacement transmission path through the threaded engagement between the rod 42 and the connecting plate 8. When the tool is inserted into the face difference adjustment hole 43 and the rod 42 is rotated, the rod 42 is driven to move in a third direction, causing the face difference disc 41 and the outer cover 1 to move synchronously. During the movement, the contact surface between the face difference disc 41 and the adjustment end cover maintains pressure transmission, ensuring that the movement of the outer cover 1 precisely corresponds to the rotation angle of the rod 42.

[0096] Compared with related technologies, traditional solutions rely on the mold of the outer cover 1 to adjust the surface difference, which requires disassembling parts and measuring actual vehicle data for each adjustment. This application, through the surface difference adjustment assembly's surface difference disc 41 and rod 42, can directly perform in-situ adjustment during the vehicle assembly stage without disassembling the outer cover 1 or reworking the mold.

[0097] Through the above technical solution, this application realizes the surface difference adjustment of the outer cover 1, eliminates the risk of part scrapping caused by repeated mold modifications in the traditional solution, and shortens the surface difference adjustment operation time to be completed within the assembly process, avoiding production line stoppage caused by rework.

[0098] Reference Figure 2 , Figure 4 , Figure 5 , Figure 9 In some embodiments of this application, the surface difference adjustment assembly further includes a surface difference adjustment end cap 2, which is fixedly disposed on the outer cover 1. A surface difference groove 12 is provided on the outer cover 1. A receiving cavity for accommodating the surface difference disk 41 is formed between the surface difference adjustment end cap 2 and the surface difference groove 12. The surface difference adjustment end cap 2 has an end cap through hole for the rod portion 42 to extend out of the receiving cavity. The base 3 has a surface difference through hole 32. The rod portion 42 passes through the end cap through hole and the surface difference through hole 32 and is threadedly connected to the connecting thread 82 of the connecting plate 8.

[0099] The surface difference groove 12 refers to the cavity structure formed by the inward indentation of the surface of the outer cover 1, which can be specifically realized by mold forming. The surface difference adjustment end cap 2 is installed on the surface of the outer cover 1 and together with the surface difference groove 12, forms a closed receiving cavity. The surface difference disk 41 is installed in the receiving cavity. The axial movement of the rod 42 drives the outer cover 1 to move in a third direction through the surface difference disk 41.

[0100] The diameter of the surface difference groove 12 is larger than the diameter of the surface difference disk 41. The surface difference disk 41 can slide within the surface difference groove 12, that is, the surface difference adjustment component 4 can slide within the surface difference groove 12.

[0101] The end cap through hole is a through hole provided on the surface difference adjustment end cap 2. Its function is to provide an axial movement channel for the rod 42 and limit the radial displacement of the rod 42.

[0102] The surface difference through hole 32 is a through hole opened on the base 3, which can be realized by machining or mold forming. Its function is to provide a moving path for the rod 42 through the base 3 and to maintain the linear movement of the rod 42 during the adjustment process.

[0103] Specifically, when it is necessary to adjust the surface difference, a tool is inserted into the surface difference adjustment hole 43 and rotated. The surface difference adjustment component 4 rotates synchronously, and the rod 42 slides relative to the connecting thread 82 on the connecting plate 8, so that the surface difference adjustment component 4 begins to move in a third direction while rotating. At the same time, when the surface difference adjustment component 4 moves axially, it synchronously drives the outer cover 1 and the surface difference adjustment end cover 2 to move, and the gap guide groove 11 on the outer cover 1 moves synchronously. Since the gap pin 6 cannot move in a third direction relative to the base 3, and the gap adjustment groove 52 on the gap adjustment component 5 cooperates with the convex ring 64, the gap adjustment component 5 cannot move in a third direction. At the same time, the spring 7 is inserted into the spring groove 51 on the gap adjustment component 5, so that the spring 7 cannot move in a third direction. Therefore, when rotating the surface difference adjustment hole 43, only the outer cover 1 is driven to move in a third direction for adjustment.

[0104] Through the above technical solution, this application simplifies the surface difference adjustment operation steps, ensures the stability of the outer cover 1 and the side panel assembly surface, and avoids the risk of parts being scrapped due to repeated adjustments.

[0105] In this embodiment, the base 3 is provided with gap limiting grooves 33 along the first and second directions, respectively, and the gap adjusting member 5 is slidably disposed in the corresponding gap limiting groove 33. Since the gap adjusting members 5 in the two directions have the same structure and operating principle, only their arrangement directions are perpendicular, the gap adjustment member 5 arranged in the first direction is taken as an example for adjusting the gap:

[0106] When gap adjustment is required, a tool is inserted into the gap adjustment hole 61 and rotated. As the convex ring 64 rotates, it drives the gap adjustment groove 52 to slide along the first direction. The gap adjustment component 5 slides synchronously, causing the spring 7 and the gap guide groove 11 on the outer cover 1 to slide synchronously. That is, the outer cover 1 slides synchronously along the first direction. Since the diameter of the surface difference groove 12 on the outer cover 1 is larger than the diameter of the surface difference disc 41 on the surface difference adjustment assembly 4, the outer cover 1 can slide relative to the surface difference adjustment assembly 4 at this moment, and the surface difference adjustment assembly 4 does not affect the sliding of the outer cover 1. Simultaneously, the gap adjustment component 5 in the second direction and the gap guide groove 11 in the other direction also slide synchronously relative to each other. Because there is a spring 7 between the gap adjustment component 5 and the gap guide groove 11, the elasticity of the spring 7 ensures that the gap adjustment groove 52 on the gap adjustment component 5 and the convex ring 64 on the gap pin 6 remain tightly fitted together, thus achieving gap adjustment of the outer cover 1.
