Description

Technical Field

[0001] This application relates to the field of vehicle structure technology, and in particular to a charging / fueling port cover structure and vehicle. Background Technology

[0002] In the design and manufacturing of modern vehicles, the charging / refueling port cover structure is a key component of the vehicle's external protection system. It not only protects the charging / refueling port from environmental damage such as dust, rain, and foreign objects, but also significantly impacts the integrity and aesthetics of the vehicle's exterior. Furthermore, a well-designed cover structure ensures convenience and safety during daily charging / refueling operations.

[0003] Currently, the cover structure is snapped onto the vehicle's charging / fueling port. In terms of disassembly design, most cover structures have a ditch designed on the corresponding outer surface of the snap-on structure. When the cover needs to be repaired, the repairman inserts a flathead screwdriver or other tools into the ditch and pries the snap-on part on the back to remove it from the sheet metal.

[0004] However, this method leaves obvious tampering marks on the exterior of the cover, severely affecting the overall aesthetics of the cover and disrupting the consistency and harmony of the vehicle's appearance. Utility Model Content

[0005] In view of the above problems, this application provides a charging / fueling port cover structure and vehicle to solve the problem that the opening affects the consistency and coordination of the vehicle's appearance.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a charging / fueling port cover structure, the charging / fueling port cover structure including a cover body, the cover body having an outer surface and an inner wall surface, the cover body being configured to cover the charging / fueling port on a vehicle.

[0008] The inner wall surface of the cover body has a first snap-fit ​​portion, and the vehicle has a second snap-fit ​​portion that matches the first snap-fit ​​portion. When the cover body is sealed at the charging / fueling port, the first snap-fit ​​portion and the second snap-fit ​​portion snap into each other.

[0009] The cap body has a breaking structure at a position corresponding to the first snap-fit ​​portion. The outer surface of the breaking structure is flush with and matches the appearance of the cap body. The strength of the breaking structure is less than the strength of the cap body, so that the breaking structure can separate from the cap body under force.

[0010] By using the strength difference design between the breaking structure and the cover body, the appearance and structural integrity are maintained when the cover is closed normally. However, since the strength of the breaking structure is less than that of the cover body, it is also easy to break it from the breaking structure so that the first snap-fit ​​part and the second snap-fit ​​part can be disengaged. This reduces the difficulty of removing the charging / fueling port cover structure and will not damage the vehicle's appearance during disassembly, thereby improving the user experience.

[0011] In one optional embodiment, the inner wall surface of the cap body has a recess at a position corresponding to the breaching structure, so that the thickness of the breaching structure is less than the thickness of the cap body. This inner wall recess, making the breaching structure thinner than the cap body, further reduces the external force threshold required for breaching.

[0012] In one optional embodiment, the thickness of the breaching structure is 0.5mm to 1mm. This thickness range balances structural strength and ease of breaching, preventing accidental detachment of the breaching structure due to vibration or scratches during daily use, achieving a balance between easy breaching and low risk of accidental breakage.

[0013] In one alternative embodiment, the outer surface of the breaching structure has a breach marking section. The breach marking section can guide the user to quickly locate the breaching position.

[0014] In one optional embodiment, the breach marking portion includes at least one of a marking pattern, a marking protrusion, and a marking recess. The marking pattern allows the breach location to be identified by visual inspection, while the marking protrusion and marking recess allow the breach location to be identified by touch.

[0015] In one alternative embodiment, the breaching marker is a circular pattern. Circular patterns are visually more focused and attract attention more easily than irregular shapes.

[0016] In one alternative embodiment, the outer surface of the cap body has a first decorative pattern, and the outer surface of the breaching structure has a second decorative pattern, wherein the first decorative pattern and the second decorative pattern are different.

[0017] The second decorative pattern on the broken structure visually distinguishes itself from the first decorative pattern on the cover body (e.g., differences in color and texture), subtly marking the broken area while maintaining overall aesthetic harmony. This avoids the marking being too abrupt and detracts from the aesthetics, while using subtle differences to remind users of the broken location, achieving a unity of functionality and decoration.

[0018] In one optional embodiment, the breaking structure and the cap body are an integral injection-molded structure.

[0019] The demolition structure and the cover body are injection molded as one piece to ensure that the connection strength between the two is reliable during normal use (such as vibration resistance and impact resistance). At the same time, due to the difference in thickness / material of the demolition structure, it can be separated along the preset interface when under force, avoiding the generation of debris or structural cracking during demolition, and ensuring the safety and structural integrity of the demolition process.

[0020] In one optional embodiment, the outer peripheral wall of the cap body has a sealing portion, the hardness of which is less than the hardness of the cap body. When the cap body is placed over the charging / filling port, the sealing portion is configured to seal the gap between the peripheral wall of the cap body and the port wall of the charging / filling port.

[0021] The sealing part can tightly fill the gap between the cover periphery and the vehicle contact surface, preventing rainwater and dust from entering the interface and causing short circuits or corrosion; at the same time, the elastic deformation capability of the low-hardness material can compensate for assembly errors, improving sealing reliability and service life.

[0022] In a second aspect, a vehicle is also provided, including a vehicle body and a charging / fueling port cover structure as described in the first aspect, wherein the vehicle body has a charging / fueling port and the charging / fueling port cover structure covers the charging / fueling port.

[0023] The vehicle is equipped with this charging / fueling port cover structure, which ensures the consistency and coordination between the interface and the vehicle's appearance through the snap-fit ​​and sealing parts during daily use. The cover body can also be disassembled by breaking the structure.

[0024] The charging / fueling port sealing structure provided in this application includes a sealing body with an outer surface and an inner wall surface. The sealing body is configured to cover the charging / fueling port on a vehicle. The inner wall surface of the sealing body has a first snap-fit ​​portion, and the vehicle has a second snap-fit ​​portion that matches the first snap-fit ​​portion. When the sealing body covers the charging / fueling port, the first snap-fit ​​portion and the second snap-fit ​​portion engage with each other. A dismantling structure is located on the sealing body at a position corresponding to the first snap-fit ​​portion. The outer surface of the dismantling structure is flush with the outer surface of the sealing body. The appearance is matched, and the strength of the breaking structure is less than that of the cover body, so that the breaking structure can be separated from the cover body under force. In this way, the boundary between the breaking structure and the cover body is almost indistinguishable in appearance, ensuring the consistency and coordination of the vehicle's appearance. However, the strength of the breaking structure is less than that of the cover body, so that it can be broken from the breaking structure to release the first snap-fit ​​part from the second snap-fit ​​part. This reduces the difficulty of removing the charging / fueling port cover structure and will not damage the vehicle's appearance during disassembly, thereby improving the user experience.

[0025] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the charging / fueling port cover structure and vehicle provided by the embodiments of this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. In embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0043] In vehicle design and manufacturing, the charging / refueling port cover structure is a key component of the vehicle's external protection system. It not only protects the charging / refueling port from environmental damage such as dust, rain, and foreign objects, but also significantly impacts the vehicle's overall appearance and aesthetics. Furthermore, a well-designed cover structure ensures convenience and safety during daily charging / refueling operations.

[0044] In the related technologies of this embodiment, there are two main methods for the disassembly design of the charging / fueling port cover structure. The following will combine... Figures 1 to 4 The demolition structure in the relevant technology is explained, among which... Figure 1 A schematic diagram of the structure of a charging / fueling port in existing technology; Figure 2 for Figure 1 Enlarged view of the breach; Figure 3 for Figure 2 Cross-sectional view of the breach; Figure 4 This application provides a structural schematic diagram of a non-disassembly breach for embodiments of the present application. In the accompanying drawings, the X direction indicates the breaching direction.

[0045] Among them, combined Figures 1 to 3 As shown, the charging port 20's cover includes a sealing structure and a breach 10. The breach 10 is designed on the outer surface corresponding to the internal snap-fit ​​part. When it is necessary to open or remove the cover, the repair personnel insert a flathead screwdriver or other tools into the breach 10, break the breach 10, and then pry open the snap-fit ​​part on the back to dislodge it. However, this design leaves a noticeable breach 10 on the outer surface of the cover, seriously affecting the overall aesthetics of the cover and disrupting the consistency and harmony of the vehicle's appearance.

[0046] Among them, such as Figure 4 As shown, some vehicle models do not have a designed opening 10 for the cover, and disassembly and assembly are carried out by forcibly pulling or prying up the edge of the cover with tools. However, this disassembly method is very likely to cause the snap-fit ​​parts to buckle and deform, and in severe cases, it can even cause the surface paint to peel off. This not only increases the risk of water leakage or rust, but also has a negative impact on the vehicle's safety and service life.

[0047] In order to overcome the defects in the existing technology and avoid the design of the opening 10 from seriously affecting the overall aesthetics of the cover and damaging the consistency and harmony of the vehicle's appearance.

[0048] The content of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can more clearly and thoroughly understand the content of this application. How to design a cover structure that ensures both a neat and aesthetically pleasing appearance for the charging / fueling port cover, facilitates quick and safe disassembly during maintenance, and does not damage other vehicle components has become a pressing technical problem to be solved.

[0050] The following sections provide a detailed description of the specific structure of the charging / fueling port cover and various possible implementation methods.

[0051] like Figure 5As shown, the charging / fueling port cover structure of this embodiment uses a two-stage injection molding process for the cover body 100. This process allows for the organic combination of materials with different properties, fully leveraging their respective advantages. The cover body 100 has a regular circular disc structure, with its diameter customized according to the charging / fueling port size of different vehicle models, commonly ranging from 150 to 100 mm, and its thickness controlled between 8 and 12 mm to ensure sufficient strength and stability. The cover body 100 has an outer surface 110 and an inner wall surface 120. The outer surface 110 faces the outside of the vehicle, and the inner wall surface 120 faces the inside of the vehicle. The cover body 100 is provided with mounting holes that match the charging / fueling port for communication between the charging / fueling port and the external charging gun / fuel gun.

[0052] The cover body 100 is a square flat plate, adapted to the corresponding square charging / fueling port on the vehicle. The cover body 100 is made of high-strength engineering plastic, possessing excellent impact resistance and weather resistance, capable of withstanding vibrations during vehicle operation, weathering, and bumps from daily use. Its outer surface 110 undergoes a special process, resulting in a smooth and flat surface, painted with the same color as the vehicle body, and treated with a wear-resistant and scratch-resistant coating to ensure consistency and aesthetics in the vehicle's appearance; the inner wall 120 retains the original texture of the plastic, facilitating structural design and functional implementation.

[0053] At the four corners of the inner wall surface 120 of the cap body 100, a first locking part 130 is provided. The first locking part 130 includes a connecting rod 131, an elastic element 132, and a locking block 133. The connecting rod 131 is connected to the locking block 133 through the elastic element 132 and has an L-shaped structure. The end of the connecting rod 131 away from the elastic element 132 is connected to the cap body 100 through an integral molding process. The locking block 133 can swing up and down in the vertical direction through the action of the elastic element 132.

[0054] The angle between the connecting rod 131 and the cap body 100 is 30° to 60°, the angle between the connecting rod 131 and the elastic element 132 is 30° to 60°, and the locking block 133 is perpendicular to the inner wall surface 120 of the cap body 100.

[0055] The bottom of the locking block 133 has a long side and a short side. The short side is located on the side closer to the elastic member 132, and the short side is located on the side farther away from the elastic member 132. The long side and the short side form a 120° angle. The length of the long side is 8mm, and the length of the short side is 5mm. The long side facilitates the smooth insertion of the first locking part 130 into the second locking part 140 when installing the cap body 100, while the short side abuts against the second locking part 140 to prevent the cap body 100 from detaching.

[0056] Correspondingly, on the inner side of the charging / fueling port of the vehicle, second engaging portions 140 are also provided at the four corners. The second engaging portion 140 is an L-shaped engaging structure that matches the engaging block 133 of the first engaging portion 130, and the second engaging portion 140 is fixed to the vehicle. The second engaging portion 140 precisely matches the first engaging portion 130, ensuring that when the first engaging portion 130 and the second engaging portion 140 are engaged, the cover body 100 can tightly and securely seal the charging / fueling port, preventing it from loosening and opening due to vibration during vehicle operation. When the cover body 100 is installed into the charging / fueling port, the second engaging portion 140 slides in along the long side of the first engaging portion 130 until the short side of the first engaging portion 130 engages with the second engaging portion 140, achieving a secure engagement.

[0057] A breaking structure 200 is provided on the cap body 100 at a position corresponding to the first snap-fit ​​portion 130. The breaking structure 200 is a square sheet structure, and its outer surface is flush with the outer surface 110 of the cap body 100. Through high-precision mold injection molding process, the appearance of the breaking structure 200 is perfectly integrated with the cap body 100, and the boundary between the breaking structure 200 and the cap body 100 is almost indistinguishable from the appearance.

[0058] The breaking structure 200 uses the same base material as the cap body 100, but the content of reinforcing fibers is reduced in the material formula and specific weakening additives are added, making the strength of the breaking structure 200 significantly less than that of the cap body 100.

[0059] A square or circular recess is provided on the inner wall surface 120 of the cover body 100 at a position corresponding to the breaching structure 200, so that the thickness of the breaching structure 200 is kept between 0.5mm and 1mm, further reducing the strength of the breaching structure 200. At the same time, the recess design can also guide the direction of the breaching force to a certain extent, making it easier for the breaching structure 200 to separate from the set position.

[0060] The outer surface of the breaching structure 200 is provided with a breaching marking section. The shape of the breaching marking section is the same as that of the breaching structure 200, and it adopts a circular marking pattern or a square marking pattern.

[0061] For example, the marking pattern is formed by laser engraving a groove with a depth of 0.1mm on the surface of the broken structure 200, and the groove is filled with a special material. Under special lighting conditions, the red marking pattern is conspicuous and easy for maintenance personnel to quickly identify, but it is indistinguishable to the naked eye under ordinary lighting.

[0062] The outer surface of the demolition structure 200 is provided with raised or recessed markings, specifically a raised or recessed ring with a height of 0.3mm, which can also help identify the position of the demolition markings by touch.

[0063] The dismantling of signage can also be achieved by combining raised signage, recessed signage, and signage patterns.

[0064] The outer surface 110 of the cover body 100 has a first decorative pattern, which is painted with simple lines and textures using the same color as the car body. The outer surface of the demolition structure 200 has a second decorative pattern, which has radial lines drawn around the circular logo pattern, forming a clear visual difference from the first decorative pattern, highlighting the position of the demolition structure 200, and facilitating quick positioning.

[0065] Combination Figure 6 and Figure 7 As shown, the breaking structure 200, the cover body 100 and the sealing part 300 are injection molded as a whole structure, specifically using two-stage injection molding.

[0066] In the secondary injection molding process, rigid plastic injection molding is performed first to form the cap body 100. The rigid plastic material is high-strength, high-toughness polycarbonate (PC), which has good impact resistance and dimensional stability and can withstand various external forces in daily use.

[0067] The first snap-fit ​​part 130 is formed by injection molding in the snap-fit ​​area on the back of the cap body 100. The inner wall surface 120 of the cap body 100 near the first snap-fit ​​part 130 is specially treated. The material is partially reduced by using a mold partial core pulling method. After the material is ejected by the slider in the mold, a recess with a depth of 3-5mm and a diameter slightly larger than the size of the first snap-fit ​​part 130 is formed on the inner side, thereby forming the disassembly structure 200.

[0068] In the injection molding method of the aforementioned cap body 100, since only one slider needs to be added to the mold, the cost of the mold will not increase.

[0069] After the hard plastic part is molded, soft plastic injection molding is performed to form the sealing part 300. The soft plastic material is a thermoplastic elastomer (TPE) with a Shore hardness of 30-40A, which has good elasticity, weather resistance and sealing performance. The soft plastic part fits tightly with the vehicle side panel, and its sealing surface is set in the recess on the back of the hard plastic part.

[0070] The soft rubber portion forms a sealing part 300 on the outer peripheral wall of the cap body 100, with a width of 5-8 mm and a thickness of 2-3 mm. When the cap body 100 is placed on the charging / fueling port, the sealing part 300 is compressed and deformed, which can effectively seal the gap between the peripheral wall of the cap body 100 and the wall of the charging / fueling port.

[0071] Combination Figures 8 to 9As shown, in terms of appearance treatment, the appearance surface 110 of the cap body 100 is first treated with a matte finish by sandblasting. The sandblasting particle size is 80-120 mesh, and the sandblasting pressure is 0.3-0.5MPa, so that the appearance surface 110 forms a uniform matte texture.

[0072] Subsequently, a circular masking film with a diameter of 1.5-2.5 mm was used to cover the area corresponding to the location of the demolished structure 200, followed by etching to create a textured surface. The etching solution used was a 15-20% ferric chloride solution, with the etching time controlled at 8-12 minutes and the temperature at 30-40℃.

[0073] As a result, a small circular area will be formed on the surface of the injection-molded cap body 100 at the corresponding position of the broken structure 200. This area has no texture, but its color tone is the same as that of the texture area. It is difficult to detect under normal viewing angle (distance 50cm, light intensity 500lux). Only careful observation can reveal the difference.

[0074] Furthermore, on the outer surface 110 of the cap body 100, corresponding to the buckle, a circular mark with a diameter of 1-2mm is provided. This mark area is not textured; instead, it is printed with white matte ink using screen printing technology, creating a clear visual contrast with the surrounding textured area. The main body surface of the cap body 100, however, is textured like a traditional cap, with the texture depth controlled between 0.05 and 0.1mm, creating a delicate texture and ensuring overall aesthetic harmony. On the inner wall 120 of the cap body 100, corresponding to the circular mark, is a recess formed by the reduced amount of hard adhesive material, i.e., the pre-designed disassembly structure 200.

[0075] When the cover needs to be removed for maintenance, the maintenance personnel can quickly locate the small round mark on the outer surface 110, insert a special screwdriver into the mark, and take advantage of the weak structure there to easily break and insert it into the first latch 130 on the back. By prying the first latch 130, it can be disengaged from the second latch 140. The entire disassembly process is simple and convenient, without the need to use excessive external force, thus effectively avoiding damage to other parts of the vehicle.

[0076] The charging / fueling port cover structure provided in this implementation is virtually indistinguishable from the boundary between the dismantled structure and the cover body in appearance, ensuring the consistency and harmony of the vehicle's appearance. Furthermore, because the dismantled structure is weaker than the cover body, it is easier to dismantle from the dismantled structure to release the first and second latching parts, thereby reducing the difficulty of removing the charging / fueling port cover structure and preventing damage to the vehicle's exterior during disassembly, thus improving the user experience.

[0077] This embodiment also provides a vehicle, including a vehicle body and the aforementioned charging / fueling port cover structure. The vehicle body is provided with a charging / fueling port, and the charging / fueling port cover structure is movably sealed to the charging / fueling port through a reasonable installation method.

[0078] During vehicle production and assembly, the assembly gap between the cover and the charging / fueling port is strictly controlled within 0.5-1mm to ensure smooth opening and closing of the cover while maintaining sealing performance. Through actual road testing and user feedback, this charging / fueling port cover structure demonstrates stable performance under normal use, a neat and aesthetically pleasing appearance, and convenient and quick disassembly and maintenance, effectively improving the overall quality of the vehicle and the user experience.
