Description

Technical Field

[0001] This disclosure relates to the field of automotive parts technology, and in particular to a charging port cover and a vehicle. Background Technology

[0002] The charging port cover is an important component of new energy vehicles. After opening the charging port cover, the vehicle can be charged by connecting an external charging device to the charging socket. After charging is completed, closing the charging port cover in time can play a role in waterproofing and dustproofing.

[0003] To balance aesthetics and manufacturing processes, charging port covers are typically located in the dry / wet separation zone. This is because they are exposed to air and susceptible to rain and water, while also needing to isolate the vehicle's "dry" and "wet" areas, preventing the "dry" area from being affected by rain or water from the "wet" area. Since vehicles sometimes need to be charged outdoors, it's impossible to guarantee protection from rain and snow during charging. Therefore, the charging port cover needs to maintain sufficient sealing performance even when open. Summary of the Invention

[0004] Therefore, this disclosure provides a charging port cover and a vehicle, which ensures sufficient sealing performance even when the charging port cover is open. The technical solution is as follows:

[0005] In a first aspect, a charging port cover is provided, the charging port cover including a cover housing and a first sealing ring;

[0006] The cap housing has a first through hole and a second through hole, and the first sealing ring includes a connected sealing ring body, a sealing inner ring and an annular sealing flange.

[0007] The sealing ring body is installed inside the first through hole, the sealing inner ring is located inside the sealing ring body, and the charging socket can extend into the inner side of the sealing inner ring from the first side of the first through hole so that the sealing inner ring and the charging socket are interference-fitted. The charging socket has a limiting shoulder located on the first side of the first through hole, and the annular sealing flange is adapted to extend from the first side of the first through hole to between the sealing ring body and the limiting shoulder, and is sandwiched between the sealing ring body and the limiting shoulder.

[0008] Wherein, the first side of the first through hole is the side of the first through hole that is opposite to the second through hole.

[0009] In one possible implementation, the annular sealing flange is made of an elastic material.

[0010] In one possible implementation, the annular sealing flange extends obliquely from the first side of the first through hole to between the sealing ring body and the limiting shoulder.

[0011] In one possible implementation, the charging port cover further includes a sealing sheet metal having an annular portion adapted to be fitted onto the charging socket and located between the sealing ring body and the limiting shoulder, wherein the surface shapes of the annular portion and the limiting shoulder are mutually adapted to each other.

[0012] The annular sealing flange is adapted to extend from the first side of the first through hole to between the annular portion and the limiting shoulder, such that the annular portion is located between the sealing ring body and the annular sealing flange, and the annular sealing flange is sandwiched between the annular portion and the limiting shoulder.

[0013] In one possible implementation, the sealing ring body is made of a rigid material, and both the inner sealing ring and the annular sealing flange are connected to the sealing ring body.

[0014] In one possible implementation, the inner sealing ring has a V-shaped cross-section, wherein the fixed end of the V-shape is connected to the sealing ring body, and the free end overlaps with the charging socket.

[0015] In one possible implementation, the central tip of the V-shape faces the second through hole.

[0016] In one possible implementation, the cap housing also has a third through hole for draining water from the cap housing.

[0017] In one possible implementation, the charging port cover further includes a drain pipe, the first end of which is connected to the inside of the port cover housing through the third through hole, and the second end of which is connected to the external space of the vehicle.

[0018] In a second aspect, a vehicle is provided, the vehicle including a charging socket and a charging port cover as described in any of the first aspects, the charging socket being mounted in a first through hole, and the charging socket having a limiting shoulder located on a first side of the first through hole.

[0019] In the solution disclosed herein, a first sealing ring is provided within the first through hole of the charging port cover. The charging socket can extend into the inner side of the sealing inner ring from the first side of the first through hole, causing the sealing inner ring to press against the charging socket. When the charging port cover is open, when rainwater enters the cover housing through the second through hole, the press against the charging socket blocks most of the water flow. In heavy rain, the sealing inner ring may not be able to completely block the water flow, allowing a small amount of water to seep in between the sealing inner ring and the charging socket. In this case, because the annular sealing flange is sandwiched between the sealing ring body and the limiting shoulder, the fit between the annular sealing flange and the limiting shoulder completely blocks the seeping water. Therefore, the charging port cover still has sufficient sealing performance when open. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0033] This embodiment relates to a charging port cover, such as... Figure 1 The diagram shown is a structural schematic of the charging port cover. Figure 2 The diagram shows the structure when the charging port cover is installed on the first side of the outer side panel 6 of the vehicle. Figure 3 The first type is shown.

Figure 8 The second type is shown. Figure 5 Schematic diagram of the enlarged part of the structure, D. Figure 9 As shown Figure 1 A schematic diagram of the BB cross-section of the charging port cover.

[0034] refer to Figure 1 As shown and Figure 2As shown, the charging port cover includes a cover housing 1 and a first sealing ring 2, and the charging port cover is generally installed on the first side of the side panel 6 of the vehicle, which is used to isolate the "dry area" inside the vehicle and the "wet area" outside the vehicle. It should be noted that the first side of the side panel 6 refers to the side of the side panel 6 facing the "dry area" inside the vehicle, and the second side is opposite to the first side, facing the "wet area" outside the vehicle.

[0035] refer to Figure 3 The diagram shows a cross-sectional view of the charging port cover installed on the first side of the outer side panel 6 of the vehicle. The outer side panel 6 has a fourth through hole. The cover housing 1 has a first through hole 11 and a second through hole 12. The cover housing 1 is installed on the first side of the outer side panel 6. For example, the cover housing 1 can be fixedly connected to the first side of the outer side panel 6 by means of adhesive or screws, and the second through hole 12 of the cover housing 1 coincides with the fourth through hole.

[0036] Continue to refer to Figure 3 As shown, the first sealing ring 2 includes a connected sealing ring body 21, a sealing inner ring 22, and an annular sealing flange 23. The sealing ring body 21 is installed inside the first through hole 11, and the sealing inner ring 22 is located inside the sealing ring body 21. The sealing ring body 21 and the cap housing 1 can be integrally formed, or they can be two independent structural parts that are fixedly connected together by snap-fit, adhesive, or other methods.

[0037] refer to Figure 4 and combined Figure 5 As shown, the charging socket 3 can extend into the annular sealing flange 23 and the inner side of the sealing inner ring 22 from the first side of the first through hole 11, so that the sealing inner ring 22 and the charging socket 3 are interference-fitted. For example, the sealing inner ring 22 can be made of soft rubber materials such as EPDM rubber, thermoplastic vulcanizate, and silicone rubber.

[0038] Continue to refer to Figure 5 As shown, the charging socket 3 has a limiting shoulder 31 located on the first side of the first through hole 11, and the annular sealing flange 23 is adapted to extend from the first side of the first through hole 11 to between the sealing ring body 21 and the limiting shoulder 31, and is sandwiched between the sealing ring body 21 and the limiting shoulder 31.

[0039] The first side of the first through hole 11 is the side of the first through hole 11 that is opposite to the second through hole 12. Since the second through hole 12 coincides with the fourth through hole, when the second through hole 12 is not blocked, that is, when the charging port cover is open, the external charging device can extend from the second side of the side panel 6 through the second through hole 12 into the door cover housing 1 and connect to the charging socket 3, thereby charging the vehicle.

[0040] As can be seen from the above, since the first through hole 11 of the charging port cover is provided with a first sealing ring 2, the charging socket 3 can extend into the inner side of the sealing inner ring 22 from the first side of the first through hole 11, so that the sealing inner ring 22 and the charging socket 3 are interference-fitted.

[0041] When the charging port cover is open, when rainwater enters the cover housing 1 through the second through hole 12, most of the water flow can be blocked by the interference fit between the sealing inner ring 22 and the charging socket 3.

[0042] During periods of heavy rainfall, the inner sealing ring 22 may not be able to completely block the water flow, allowing a small amount of water to seep in between the inner sealing ring 22 and the charging socket 3. In this case, because the annular sealing flange 23 is sandwiched between the sealing ring body 21 and the limiting shoulder 31, the fit between the annular sealing flange 23 and the limiting shoulder 31 completely blocks the seepage of water. Therefore, the charging port cover maintains sufficient sealing performance even when open.

[0043] In one example, the annular sealing flange 23 is made of an elastic material, such as EPDM rubber, thermoplastic vulcanizate, or silicone rubber. Because the annular sealing flange 23 is elastic, when it is sandwiched between the annular portion 41 and the sealing ring body 21, it can deform to adapt to the shape between the sealing ring body 21 and the limiting shoulder 31, thereby improving the sealing performance.

[0044] In one example, the annular sealing flange 23 extends obliquely from the first side of the first through hole 11 to between the sealing ring body 21 and the limiting shoulder 31.

[0045] When the charging socket 3 is inserted into the first side of the first through hole 11 and installed inside the inner sealing ring 22, the limiting shoulder 31 of the charging socket 3 can press the annular sealing flange 23 against the sealing ring body 21, so that the annular sealing flange 23 is clamped between the sealing ring body 21 and the limiting shoulder 31.

[0046] In this way, since the annular sealing flange 23 extends obliquely from the first side of the first through hole 11, when the annular sealing flange 23 is sandwiched between the annular portion 41 and the limiting shoulder 31, the annular sealing flange 23 will have a force toward the limiting shoulder 31 and want to return to its original state, making the fit between the annular sealing flange 23 and the limiting shoulder 31 tighter, thereby further improving the sealing performance.

[0047] In one example, the angle between the annular sealing flange 23 and the limiting shoulder 31 in its natural state can be from 25° to 60°. For example, the angle between the annular sealing flange 23 and the limiting shoulder 31 in its natural state can be 25°, 45°, or 60°. In this way, when the charging socket 3 is installed inside the inner sealing ring 22, the limiting shoulder 31 can easily press the annular sealing flange 23 onto the sealing ring body 21, which facilitates installation and ensures better sealing performance.

[0048] In one example, refer to Figure 6 The diagram shows a structural schematic of the charging port cover with a sealing sheet metal 4. Figure 7 The enlarged schematic diagram D shows the interference between the annular sealing flange 23 and the limiting shoulder 31. Figure 8 The enlarged schematic diagram D shows the annular sealing flange 23 being pressed against the annular portion 41 of the sealing sheet metal 4. The charging port cover also includes the sealing sheet metal 4, which has an annular portion 41. The annular portion 41 is adapted to be fitted onto the charging socket 3 and is located between the sealing ring body 21 and the limiting shoulder 31. The surface shapes of the annular portion 41 and the limiting shoulder 31 are mutually compatible and close to each other.

[0049] For example, the surface of the annular portion 41 near the limiting shoulder 31 can be a plane, and correspondingly, the surface of the limiting shoulder 31 near the annular portion 41 can also be a plane; or, for another example, the surface of the annular portion 41 near the limiting shoulder 31 can be a curved surface, and correspondingly, the surface of the limiting shoulder 31 near the annular portion 41 can also be a curved surface.

[0050] Continue to refer to Figure 7 and Figure 8 As shown, the annular sealing flange 23 is adapted to extend from the first side of the first through hole 11 to between the annular portion 41 and the limiting shoulder 31, such that the annular portion 41 is located between the sealing ring body 21 and the annular sealing flange 23, and the annular sealing flange 23 is sandwiched between the annular portion 41 and the limiting shoulder 31.

[0051] like Figure 7 As shown, there is a certain amount of interference between the annular sealing flange 23 and the limiting shoulder 31. When the charging socket 3 is inserted into the first side of the first through hole 11 and installed inside the inner sealing ring 22, the limiting shoulder 31 of the charging socket 3 needs to press the annular sealing flange 23 against the sealing ring body 21. In this way, the annular sealing flange 23 will present the following appearance. Figure 8 The state shown is that it is pressed between the annular portion 41 and the limiting shoulder 31.

[0052] As described above, the annular portion 41 of the sealing sheet metal 4 is located between the sealing ring body 21 and the annular sealing flange 23, allowing the annular sealing flange 23 to be pressed between the annular portion 41 and the limiting shoulder 31. Compared to the method where the annular sealing flange 23 is directly clamped between the limiting shoulder 31 and the sealing ring body 21, the annular sealing flange 23 can better adapt to the surface shapes of the annular portion 41 and the limiting shoulder 31 because their close proximity allows for better deformation. This results in a better fit and interference fit with the annular portion 41 and the limiting shoulder 31, thus enabling the annular sealing flange 23 to be clamped more stably and providing better sealing performance.

[0053] Meanwhile, due to the pressing of the annular part 41 and the limiting shoulder 31 on the annular sealing flange 23, the annular sealing flange 23 has a strong adaptability to colder rain and snow weather, and is not prone to deformation after being cooled, thus reducing the sealing performance.

[0054] In one example, the sealing ring body 21 is made of a rigid material, such as hard plastic or rigid polyvinyl chloride. The inner sealing ring 22 and the annular sealing flange 23 are both connected to the sealing ring body 21.

[0055] The inner sealing ring 22, the annular sealing flange 23, and the sealing ring body 21 can be integrally formed or they can be independent structural components that are fixedly connected together by snap-fit ​​or adhesive.

[0056] For example, the sealing inner ring 22, the annular sealing flange 23 and the sealing ring body 21 can be integrally injection molded to form the first sealing ring 2 through a two-color injection molding process. The sealing ring body 21 is made of hard rubber, while the sealing inner ring 22 and the annular sealing flange 23 are made of soft rubber.

[0057] For example, the inner sealing ring 22, the annular sealing flange 23, and the sealing ring body 21 are independent structural components. Glue is applied to the inner side of the sealing ring body 21 and the side near the first through hole 11, and then the sealing ring body 21 and the annular sealing flange 23 are glued to the sealing ring body 21.

[0058] In this way, by connecting the elastic sealing inner ring 22 and the annular sealing flange 23 to the rigid sealing ring body 21, the sealing ring body 21 can play a certain shaping role for the sealing inner ring 22 and the annular sealing flange 23, thus avoiding deviation or deformation of the sealing inner ring 22 and the annular sealing flange 23 during installation, which would affect the sealing performance.

[0059] In one example, continue to refer to Figure 7As shown, the inner sealing ring 22 has a V-shaped cross-section, with the fixed end of the V-shape connected to the sealing ring body 21 and the free end overlapping the charging socket 3. The V-shaped cross-section of the inner sealing ring 22 can form a water-blocking groove, preventing rainwater from directly reaching between the inner sealing ring 22 and the charging socket 3, thus improving the rainwater blocking effect.

[0060] In one example, the middle tip of the V-shape faces the second through hole 12. Thus, since the free end overlaps with the charging socket 3, when rainwater overflows onto the sealing inner ring 22, the fit between the sealing inner ring 22 and the charging socket 3 will be tighter, thereby further improving the sealing performance.

[0061] In one example, refer to Figure 9 As shown, the cap housing 1 also has a third through hole 13, which is used to drain water from inside the cap housing 1. For example Figure 9 As shown, the third through hole 13 is located on the lower side wall of the cover housing 1 and is at its lowest position. In this way, water inside the cover housing 1 can be drained in a timely manner through the third through hole 13, thereby avoiding excessive water accumulation inside the cover housing 1 for a long time, which would cause the overlapping area between the sealing inner ring 22 and the charging socket 3 to be soaked in water for a long time and affect its sealing performance.

[0062] In one example, refer to Figure 1 As shown, the charging port cover also includes a drain pipe 5. The first end of the drain pipe 5 is connected to the inside of the cover housing 1 through the third through hole 13, and the second end is connected to the external space of the vehicle. In this way, water inside the cover housing 1 can be directly drained to the outside of the vehicle through the drain pipe 5.

[0063] In one example, refer to Figure 6 As shown, the charging port cover also includes a port cover outer plate 7, which is installed at the second through hole 12 and used to open or close the second through hole 12. The port cover outer plate 7 can be a rotary port cover outer plate 7, or it can be as shown... Figure 6 The inner sliding outer cover 7 shown in this embodiment does not limit the opening and closing form of the outer cover 7, as long as the outer cover 7 can be closed at the second through hole 12 and the outer cover 7 can be opened by moving away from the second through hole 12.

[0064] In order for the outer cover plate 7 to be sealed at or away from the second through hole 12, the outer cover plate 7 can be connected to the motor through a transmission mechanism and transmit a switch signal through the controller.

[0065] When the controller receives a signal to open the outer cover 7, it sends an open signal to the motor, controlling the motor to start and actuating the outer cover 7 via the transmission mechanism, causing the outer cover 7 to move away from the second through hole 12, thus opening the charging port cover. When the controller receives a signal to close the outer cover 7, it sends a close signal to the motor, controlling the motor to start and actuating the outer cover 7 via the transmission mechanism, causing the outer cover 7 to seal at the second through hole 12, thus closing the charging port cover.

[0066] In this way, when the vehicle is not being charged, the outer cover 7 can seal the second through hole 12 and close the charging port cover, thus providing dust and water protection. When charging is required, the outer cover 7 can move away from the second through hole 12, allowing the second through hole 12 to be opened, thereby allowing external charging equipment to extend into the cover housing 1 through the second through hole 12 and connect to the charging socket 3 to charge the vehicle.

[0067] In one example, continue to refer to Figure 6 As shown, the charging port cover also includes a second sealing ring 121. The second sealing ring 121 is installed on the port cover housing 1 and surrounds the second through hole 12. When the port cover outer plate 7 blocks the second through hole 12, the second sealing ring 121 is sandwiched between the port cover outer plate 7 and the port cover housing 1, and abuts against the port cover outer plate 7 and the port cover housing 1 at the same time, thereby sealing the second through hole 12.

[0068] In one example, continue to refer to Figure 3 As shown, the lower edge of the second through hole 12 is lower than the lower edge of the first through hole 11. In this way, when the water volume is too large, the water can overflow directly from the second through hole 12, avoiding the third through hole 13 from being unable to drain the water in the cap housing 1 in time, which would result in too much water in the cap housing 1, causing the overlapping area between the sealing inner ring 22 and the charging socket 3 to be soaked in water for a long time and affecting its sealing performance.

[0069] In one example, to facilitate the installation of the charging port cover on the side panel 6 and the assembly of the charging socket 3 with the charging port cover, the cover housing 1 includes a lower cover housing 101 and an upper cover housing 102. The lower cover housing 101 and the upper cover housing 102 are detachably connected by bolts, snap-fits, or other means to form the cover housing 1. A first through hole 11 is located on the lower cover housing 101, and a second through hole 12 is located on the upper cover housing 102.

[0070] During assembly, the second through hole 12 of the upper cover housing 102 can be aligned with the fourth through hole of the side outer plate 6, and the upper cover housing 102 can be fixed to the first side of the side outer plate 6 by means of screws, adhesives, etc., and then the lower cover housing 101 can be assembled onto the upper cover housing 102.

[0071] Subsequently, the annular portion 41 of the sealing sheet metal 4 is pressed against the first side of the first through hole 11, and the annular sealing flange 23 is turned out so that the annular portion 41 is located between the annular sealing flange 23 and the sealing ring body 21.

[0072] Finally, the charging socket 3 is inserted from the first side of the first through hole 11 into the inner side of the annular sealing flange 23 and the inner sealing ring 22 until the limiting shoulder 31 of the charging socket 3 presses the annular sealing flange 23 onto the annular part 41, thereby completing the assembly.

[0073] In one example, the lower housing 101 of the cover, the sealing ring body 21, the inner sealing ring 22, and the annular sealing flange 23 can be integrally formed or they can be independent structural components that are fixedly connected together by snap-fit ​​or adhesive.

[0074] In one example, the sealing sheet metal 4 is fixed inside the vehicle. After the annular sealing flange is pressed onto the annular portion of the sealing sheet metal 4 by the limiting shoulder 31 of the charging socket 3, the sealing sheet metal 4 and the charging socket 3 can be fixedly connected by screws, snap-fits, or other means. For example, the annular portion 41 of the sealing sheet metal 4 and the limiting shoulder 31 of the charging socket 3 can be fixedly connected by screws, snap-fits, or other means.

[0075] In this embodiment, since the first through hole 11 of the charging port cover is provided with a first sealing ring 2, the charging socket 3 can extend into the inner side of the sealing inner ring 22 from the first side of the first through hole 11, so that the sealing inner ring 22 and the charging socket 3 are interference-fitted.

[0076] When the charging port cover is open, when rainwater enters the cover housing 1 through the second through hole 12, most of the water flow can be blocked by the interference fit between the sealing inner ring 22 and the charging socket 3.

[0077] During periods of heavy rainfall, the inner sealing ring 22 may not be able to completely block the water flow, allowing a small amount of water to seep in between the inner sealing ring 22 and the charging socket 3. In this case, because the annular sealing flange 23 is sandwiched between the sealing ring body 21 and the limiting shoulder 31, the fit between the annular sealing flange 23 and the limiting shoulder 31 completely blocks the seepage of water. Therefore, the charging port cover maintains sufficient sealing performance even when open.

[0078] This disclosure also provides a vehicle, which includes a charging socket 3 and a charging port cover as described in any of the first aspects. The charging socket 3 is installed in a first through hole 11, and the charging socket 3 has a limiting shoulder 31 located on a first side of the first through hole 11. The vehicle has a side panel 6 with a fourth through hole, and a port cover housing 1 is installed on the first side of the side panel 6. For example, the port cover housing 1 can be fixedly connected to the first side of the side panel 6 by adhesive or screws, and the second through hole 12 of the port cover housing 1 coincides with the fourth through hole.

[0079] In this embodiment, since the first through hole 11 of the charging port cover is provided with a first sealing ring 2, the charging socket 3 can extend into the inner side of the sealing inner ring 22 from the first side of the first through hole 11, so that the sealing inner ring 22 and the charging socket 3 are interference-fitted.

[0080] When the charging port cover is open, when rainwater enters the cover housing 1 through the second through hole 12, most of the water flow can be blocked by the interference fit between the sealing inner ring 22 and the charging socket 3.

[0081] During periods of heavy rainfall, the inner sealing ring 22 may not be able to completely block the water flow, allowing a small amount of water to seep in between the inner sealing ring 22 and the charging socket 3. In this case, because the annular sealing flange 23 is sandwiched between the sealing ring body 21 and the limiting shoulder 31, the fit between the annular sealing flange 23 and the limiting shoulder 31 completely blocks the seepage of water. Therefore, the charging port cover maintains sufficient sealing performance even when open.
