Technical Field

[0001] The present disclosure relates to the technical field of automobile parts, and in particular to a charging port cover and a vehicle. Background Art

[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 the charging socket through an external charging device. After charging is completed, closing the charging port cover in time can play a role in waterproofing and dustproofing.

[0003] In order to take into account both the shape and the craftsmanship, the charging port cover is generally placed in the dry-wet boundary area. On the one hand, it is exposed to the air and easily affected by rain and water. On the other hand, it needs to isolate the "dry area" and "wet area" of the vehicle to prevent the "dry area" from being affected by rain and water in the "wet area". Sometimes, the vehicle has to be charged outdoors, and it is impossible to ensure that it can avoid rain and snow during charging. Therefore, the charging port cover needs to have sufficient sealing performance when it is opened. Summary of the invention

[0004] In view of this, the embodiments of the present disclosure provide a charging port cover and a vehicle, so that the charging port cover still has sufficient sealing performance when it is opened. The technical solution is as follows:

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

[0006] The cover housing has a first through hole and a second through hole opposite to each other, and the first sealing ring comprises a connected sealing ring body, a sealing inner ring and an annular sealing flange;

[0007] The sealing ring body is installed on the inner side of the first through hole, the sealing inner ring is located on the inner side of 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 overlapped by interference, the charging socket has a limiting shoulder located on the first side of the first through hole, and the annular sealing flange is suitable for extending from the first side of the first through hole to between the sealing ring body and the limiting shoulder, and is clamped between the sealing ring body and the limiting shoulder;

[0008] The first side of the first through hole is a side of the first through hole facing away from the second through hole.

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

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

[0011] In a possible implementation, the charging port cover further includes a sealing sheet metal, the sealing sheet metal having an annular portion, the annular portion being suitable for being sleeved on the charging socket and being located between the sealing ring body and the limiting shoulder, and the surface shapes of the annular portion and the limiting shoulder being close to each other are adapted to each other;

[0012] The annular sealing flange is suitable for extending from the first side of the first through hole to between the annular portion and the limiting shoulder, so that the annular portion is located between the sealing ring body and the annular sealing flange, and the annular sealing flange is clamped between the annular portion and the limiting shoulder.

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

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

[0015] In a possible implementation manner, a tip of a middle portion of the V-shape faces the second through hole.

[0019] In the solution disclosed in the present invention, a first sealing ring is provided in the first through hole of the charging port cover, and the charging socket can extend from the first side of the first through hole into the inner side of the sealing inner ring, so that the sealing inner ring and the charging socket are overlapped by interference. When the charging port cover is in the open state, when rainwater enters the cover shell from the second through hole, most of the water flow can be blocked by the interference overlap between the sealing inner ring and the charging socket. When the rainwater is heavy, the sealing inner ring may not be able to completely block the water flow, so that a small amount of water penetrates from between the sealing inner ring and the charging socket. At this time, since the annular sealing flange is clamped between the sealing ring body and the limiting shoulder, the cooperation between the annular sealing flange and the limiting shoulder completely blocks the small amount of water that penetrates. Therefore, the charging port cover still has sufficient sealing performance when it is in the open state. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0033] This embodiment relates to a charging port cover, such as Figure 1 The figure shows the structure of the charging port cover. Figure 2 The figure shows a schematic diagram of the structure when the charging port cover is installed on the first side of the vehicle side outer panel 6. Figure 3 The first one is shown Figure 1 AA cross-section diagram of the middle charging port cover. Figure 4 The second one is shown Figure 1 AA cross-section diagram of the middle charging port cover. Figure 5 Shown Figure 4 Schematic diagram of the local enlarged structure C, Figure 6 The third type is shown Figure 1 AA cross-section diagram of the middle charging port cover. Figure 7 The first one is shown Figure 5 The local enlarged structural diagram D, Figure 8 The second one is shown Figure 5 The local enlarged structural diagram D, Fig. 9 Shown Figure 1 BB cross-section diagram of the middle charging port cover.

[0034] refer to Figure 1 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 for isolating 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, which is the side facing the "wet area" outside the vehicle.

[0035] refer to Figure 3 What is shown is an AA cross-sectional schematic diagram when the charging port cover is installed on the first side of the side outer panel 6 of the whole vehicle. A fourth through hole is opened on the side outer panel 6, and the cover shell 1 has a first through hole 11 and a second through hole 12 relative to each other. The cover shell 1 is installed on the first side of the side outer panel 6. For example, the cover shell 1 can be fixedly connected to the first side of the side outer panel 6 by gluing or screws, and the second through hole 12 of the cover shell 1 coincides with the fourth through hole.

[0036] Continue to refer 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 on the inner side of the first through hole 11, and the sealing inner ring 22 is located on the inner side of the sealing ring body 21. The sealing ring body 21 and the cover housing 1 can be integrally formed, or can be two independent structural parts fixedly connected together by means of clamping, gluing, etc.

[0037] refer to Figure 4 Combined with Figure 5 As shown, the charging socket 3 can extend from the first side of the first through hole 11 into the annular sealing flange 23 and the inner side of the sealing inner ring 22, so that the sealing inner ring 22 and the charging socket 3 are overlapped with each other. For example, the sealing inner ring 22 can be made of soft rubber material such as EPDM rubber, thermoplastic vulcanized rubber, silicone rubber, etc.

[0038] Continue to refer 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 suitable for extending from the first side of the first through hole 11 to between the sealing ring body 21 and the limiting shoulder 31, and being clamped 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 away from the second through hole 12. And because 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, an external charging device can extend from the second side of the side outer panel 6 through the second through hole 12 into the port cover housing 1 and connect to the charging socket 3, thereby charging the vehicle.

[0040] From the above, it can be seen that since the first sealing ring 2 is provided in the first through hole 11 of the charging port cover, the charging socket 3 can extend from the first side of the first through hole 11 into the inner side of the sealing inner ring 22, so that the sealing inner ring 22 and the charging socket 3 are overlapped with each other.

[0041] When the charging port cover is in the open state, when rainwater enters the cover housing 1 from 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] When the rain is heavy, the sealing inner ring 22 may not be able to completely block the water flow, so a small amount of water may penetrate from the sealing inner ring 22 and the charging socket 3. At this time, since the annular sealing flange 23 is clamped between the sealing ring body 21 and the limiting shoulder 31, the cooperation between the annular sealing flange 23 and the limiting shoulder 31 completely blocks the small amount of water that penetrates. Therefore, the charging port cover still has sufficient sealing performance when it is opened.

[0043] In one example, the annular sealing flange 23 is made of an elastic material, for example, the annular sealing flange 23 can be made of a soft rubber material such as EPDM rubber, thermoplastic vulcanizate, silicone rubber, etc. In this way, since the annular sealing flange 23 is elastic, when the annular sealing flange 23 is clamped between the annular portion 41 and the sealing ring body 21, it can adapt to the shape between the sealing ring body 21 and the limiting shoulder 31 through deformation, so that the sealing performance is improved.

[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 extended from the first side of the first through hole 11 and installed on the inner side of the sealing inner ring 22 , the limiting shoulder 31 of the charging socket 3 can press the annular sealing flange 23 toward 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 clamped 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 restore its original state, so that the fit between the annular sealing flange 23 and the limiting shoulder 31 is 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 the natural state can be 25° to 60°. For example, the angle between the annular sealing flange 23 and the limiting shoulder 31 in the natural state can be 25°, 45°, or 60°. In this way, when the charging socket 3 is installed on the inner side of the sealing inner ring 22, the limiting shoulder 31 can press the annular sealing flange 23 onto the sealing ring body 21, which is convenient for installation and can also ensure better sealing.

[0048] In one example, reference Figure 6 The figure shows a schematic diagram of the structure of the charging port cover with a sealing sheet metal 4. Figure 7 The partially enlarged structural schematic diagram D shown is a schematic diagram showing interference between the annular sealing flange 23 and the limiting shoulder 31. Figure 8 The partial enlarged structural schematic diagram D is a schematic diagram of the annular sealing flange 23 being pressed against the annular portion 41 of the sealing sheet metal 4. The charging port cover also includes a sealing sheet metal 4, which has an annular portion 41. The annular portion 41 is suitable for being sleeved on the charging socket 3 and 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 that are close to each other are adapted to each other.

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

[0050] Continue to refer Figure 7 and Figure 8 As shown, the annular sealing flange 23 is suitable for extending from the first side of the first through hole 11 to between the annular portion 41 and the limiting shoulder 31, so 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 clamped between the annular portion 41 and the limiting shoulder 31.

[0051] like Figure 7 As shown in FIG. 1 , 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 from the first side of the first through hole 11 and installed inside the sealing inner ring 22, the limiting shoulder 31 of the charging socket 3 needs to press the annular sealing flange 23 toward the sealing ring body 21. In this way, the annular sealing flange 23 will present a Figure 8 The state shown is that it is compressed between the annular portion 41 and the limiting shoulder 31 .

[0052] From the 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, so that the annular sealing flange 23 can be pressed between the annular portion 41 and the limiting shoulder 31. Compared with the way that the annular sealing flange 23 is directly clamped between the limiting shoulder 31 and the sealing ring body 21, since the surface shapes of the annular portion 41 and the limiting shoulder 31 close to each other are adapted to each other, the annular sealing flange 23 can better produce a corresponding deformation, so that it can better fit and interfere with the annular portion 41 and the limiting shoulder 31, so that the annular sealing flange 23 can be clamped more stably and have better sealing performance.

[0053] At the same time, due to the compression of the annular portion 41 and the limiting shoulder 31 on the annular sealing flange 23, the annular sealing flange 23 has a strong adaptability to cold rainy and snowy weather and is not prone to deformation and reduced sealing performance after being cold.

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

[0055] The sealing inner ring 22, the annular sealing flange 23 and the sealing ring body 21 may be integrally formed, or may be independent structural parts fixedly connected together by means of snap-fitting or gluing.

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

[0057] For another example, the sealing inner ring 22, the annular sealing flange 23 and the sealing ring body 21 are independent structural parts. Glue is applied to the inner side of the sealing ring body 21 and the side close to the first side of the first through hole 11, and then the sealing ring body 21 and the annular sealing flange 23 are bonded to the sealing ring body 21 by glue.

[0058] In this way, by connecting the sealing inner ring 22 and the annular sealing flange 23 made of elastic material to the sealing ring body 21 made of rigid material, the sealing inner ring 22 and the annular sealing flange 23 can be shaped to a certain extent by the sealing ring body 21, thereby avoiding the sealing inner ring 22 and the annular sealing flange 23 from position deviation or deformation during installation, thereby affecting the sealing performance.

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

[0060] In one example, the tip of the middle portion of the V-shape faces the second through hole 12. In this way, since the free end overlaps with the charging socket 3, when the tip of the middle portion of the V-shape faces the second through hole 12, 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, reference Fig. 9 As shown, the mouth cover housing 1 also has a third through hole 13, and the third through hole 13 is used to discharge water in the mouth cover housing 1. Fig. 9 As shown, the third through hole 13 is located on the lower side wall of the cover housing 1 and is at the lowest position. In this way, the water in the cover housing 1 can be discharged in time through the third through hole 13, thereby preventing excessive water from accumulating in the cover housing 1 for a long time, 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.

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

[0063] In one example, reference 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 is used to open or close the second through hole 12. The port cover outer plate 7 can be a rotating port cover outer plate 7 or a Figure 6 As shown in the inward sliding opening cover outer plate 7, the present embodiment does not limit the opening and closing form of the opening cover outer plate 7, as long as the opening cover outer plate 7 can block the second through hole 12 so that the charging opening cover is closed, and the opening cover outer plate 7 can leave the second through hole 12 so that the charging opening cover is opened.

[0064] In order to make the cover outer plate 7 block the second through hole 12 or leave the second through hole 12, the cover outer plate 7 can be connected to the motor through a transmission mechanism and transmit a switch signal through a controller.

[0065] When the controller receives a signal to open the cover outer plate 7, it sends an opening signal to the motor, controls the motor to start, and actuates the cover outer plate 7 through the transmission mechanism, so that the cover outer plate 7 leaves the second through hole 12, so that the charging cover is opened. When the controller receives a signal to close the cover outer plate 7, it sends a closing signal to the motor, controls the motor to start, and actuates the cover outer plate 7 through the transmission mechanism, so that the cover outer plate 7 blocks the second through hole 12, so that the charging cover is closed.

[0066] In this way, when the vehicle is not being charged, the cover outer plate 7 can block the second through hole 12 and close the charging cover to prevent dust and water; when charging is needed, the cover outer plate 7 can leave the second through hole 12 so that the second through hole 12 is opened, thereby allowing an external charging device to extend from the second through hole 12 into the cover shell 1 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, which is installed on the port cover shell 1 and surrounds the second through hole 12, and when the port cover outer plate 7 blocks the second through hole 12, the second sealing ring 121 is clamped between the port cover outer plate 7 and the port cover shell 1, and abuts against the port cover outer plate 7 and the port cover shell 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 amount of water is too large, the water can overflow directly from the second through hole 12, avoiding the third through hole 13 from being unable to discharge the water in the port cover shell 1 in time, resulting in excessive water in the port cover shell 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, in order to facilitate the installation of the charging port cover on the side outer panel 6, and the assembly of the charging socket 3 and the charging port cover, the port cover housing 1 includes a port cover lower housing 101 and a port cover upper housing 102. The port cover lower housing 101 and the port cover upper housing 102 can be detachably connected by bolts, snap-fitting, etc. to form the port cover housing 1, the first through hole 11 is located on the port cover lower housing 101, and the second through hole 12 is located on the port cover upper housing 102.

[0070] During assembly, the second through hole 12 of the mouth cover upper shell 102 can be aligned with the fourth through hole of the side outer panel 6, and the mouth cover upper shell 102 can be fixed to the first side of the side outer panel 6 by screws, gluing, etc., and then the mouth cover lower shell 101 can be assembled on the mouth cover upper shell 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 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 until the limiting shoulder 31 of the charging socket 3 presses the annular sealing flange 23 onto the annular portion 41, thereby completing the assembly.

[0073] In one example, the lower shell 101 of the cover and the sealing ring body 21, the sealing inner ring 22 and the annular sealing flange 23 can be integrally formed, or can be independent structural parts fixedly connected together by means of snap-fitting or bonding.

[0074] In one example, the sealing sheet metal 4 is fixed inside the car, and after the annular sealing flange is pressed against the annular portion of the sealing sheet metal 4 by the limiting shoulder 31 of the charging socket 3, the sealing sheet metal 4 can be fixedly connected to the charging socket 3 by means of screws, clamping, etc. For example, the annular portion 41 of the sealing sheet metal 4 is fixedly connected to the limiting shoulder 31 of the charging socket 3 by means of screws, clamping, etc.

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

[0076] When the charging port cover is in the open state, when rainwater enters the cover housing 1 from 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] When the rain is heavy, the sealing inner ring 22 may not be able to completely block the water flow, so a small amount of water may penetrate from the sealing inner ring 22 and the charging socket 3. At this time, since the annular sealing flange 23 is clamped between the sealing ring body 21 and the limiting shoulder 31, the cooperation between the annular sealing flange 23 and the limiting shoulder 31 completely blocks the small amount of water that penetrates. Therefore, the charging port cover still has sufficient sealing performance when it is opened.

[0078] The embodiment of the present disclosure further provides a vehicle, the vehicle comprising a charging socket 3 and a charging cover as described in any one of the first aspects, the charging socket 3 being installed in the first through hole 11, and the charging socket 3 having a limiting shoulder 31 located on the first side of the first through hole 11. The vehicle has a side panel 6 having a fourth through hole, and the cover housing 1 is installed on the first side of the side panel 6, for example, the cover housing 1 can be fixedly connected to the first side of the side panel 6 by gluing or screws, and the second through hole 12 of the cover housing 1 coincides with the fourth through hole.

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

[0080] When the charging port cover is in the open state, when rainwater enters the cover housing 1 from 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] When the rain is heavy, the sealing inner ring 22 may not be able to completely block the water flow, so a small amount of water may penetrate from the sealing inner ring 22 and the charging socket 3. At this time, since the annular sealing flange 23 is clamped between the sealing ring body 21 and the limiting shoulder 31, the cooperation between the annular sealing flange 23 and the limiting shoulder 31 completely blocks the small amount of water that penetrates. Therefore, the charging port cover still has sufficient sealing performance when it is opened.
