Description

Technical Field

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

[0002] With the development of new energy technologies, the number of electric vehicles is increasing. Charging port covers are installed on electric vehicles to open and close the charging port. The hinge arm is a key component of the charging port cover. The hinge arm is typically made of nylon with fiberglass. Nylon is susceptible to moisture. In the atmosphere, the equilibrium water absorption rate of nylon is 3.5%, and that of PA66 is 2.5%. Over long-term use, the hinge arm can easily absorb moisture and deform due to exposure to rain or car washing. This can cause the gap in the charging port cover to distort, resulting in an unsightly appearance and a poor user experience. In severe cases, it can also cause deformation and unusual noise. Summary of the Invention

[0003] In view of the above shortcomings of the prior art, the present invention provides a charging port cover to improve the technical problems of the existing charging port cover hinge arm being easily deformed by water absorption, affecting the appearance and even causing abnormal noise.

[0004] To achieve the above-mentioned purpose and other related purposes, the present invention provides a charging port cover, comprising: a base, fixed on the vehicle body, and provided with an outer peripheral opening; an outer panel, rotating with the base, the outer panel being configured to cover and expose the base on the vehicle body; a hinge arm, rotatably connected to the base and fixed to the outer panel, the hinge arm comprising: a connecting portion, rotatably connected to the base; a main body portion, fixed to the connecting portion, the main body portion being inserted into the outer peripheral opening when the outer panel covers the base; a soft rubber portion, arranged on the outer periphery of the main body portion close to the outer panel side, the soft rubber portion abutting against the peripheral side of the outer peripheral opening when the outer panel covers the base; wherein the soft rubber portion is in interference fit against the outer panel, and a hydrophobic groove is formed around the main body portion between the soft rubber portion and the outer panel.

[0005] In an exemplary embodiment of the present application, the soft rubber portion includes a first protruding portion and a second protruding portion, the first protruding portion abuts against the outer panel, and the second protruding portion abuts against the outer periphery of the outer peripheral opening; wherein the cross-section of the second protruding portion is arc-shaped, and the arc-shaped opening faces the outer peripheral opening.

[0006] In an exemplary embodiment of the present application, a protrusion is provided on the outer periphery of the main body, and the soft rubber portion is injection-molded on the protrusion and covers the protrusion.

[0007] In an exemplary embodiment of the present application, a plurality of clamping parts are provided on a side of the main body close to the outer panel, and a clamping block is provided on the outer panel, and the clamping block is plug-in connected to the clamping part.

[0008] In an exemplary embodiment of the present application, the clamping portion includes a first limiting plate fixed to the main body portion, and a second limiting plate arranged on the side of the first limiting plate away from the main body portion, and the second limiting plates arranged on the upper and lower sides of the main body portion extend in opposite directions; the clamping block is inserted into the clamping portion from the side of the clamping portion away from the connecting portion.

[0009] In an exemplary embodiment of the present application, a push switch is provided on the base, and a push protrusion is provided on the main body, and the push protrusion cooperates with the push switch.

[0010] In an exemplary embodiment of the present application, a through hole is provided on the pressing protrusion, and a pressing soft rubber is provided in the through hole, and the pressing soft rubber protrudes from the through hole away from the outer panel.

[0011] In an exemplary embodiment of the present application, a cross-section of the pressing soft rubber close to the outer panel is smaller than a cross-section of the pressing soft rubber protruding from the main body.

[0012] In an exemplary embodiment of the present application, the pressing soft rubber and the soft rubber portion are integrally formed.

[0013] The present application also provides a vehicle, comprising the charging port cover described in any one of the above items.

[0014] The beneficial effects of the present invention are:

[0015] The hinge arm of the existing charging port cover easily absorbs water and deforms, causing the charging port cover to twist and deform, affecting the appearance, and in severe cases, causing abnormal noises. The hinge arm of the charging port seat of the present application includes a main body and a soft rubber part, wherein the soft rubber part is arranged on the periphery of the main body, and the soft rubber part abuts the outer panel. When it rains or when washing the car, water leaks into the charging port through the gap between the outer panel and the car body. The soft rubber part abuts the outer panel with an interference fit, blocking the water flow on the outside of the soft rubber part, that is, water cannot enter the main body through the gap between the outer panel and the main body, thereby effectively reducing the water absorption and deformation of the main body, increasing the service life of the charging port cover, and improving the user experience.

[0016] A hydrophobic groove is formed between the soft rubber portion and the outer panel around the main body. Water that leaks through the outer panel into the charging port flows out through the hydrophobic groove under the action of gravity, avoiding water accumulation and preventing water from leaking into the main body or the charging port.

[0017] The soft rubber part of the present application rests against the peripheral side of the outer peripheral opening of the base when the charging port cover is in the buckled state, thereby achieving sealing of the outer peripheral opening, preventing water from entering the charging port in rainy or car washing conditions, and improving protection of the charging port.

[0033] When the charging port cover is fastened, there is a gap between it and the vehicle body. During rain or car washing, water can enter the cover through this gap. The hinge arm 300 of the charging port cover is typically fastened to the outer panel 200. Water can flow along the outer panel 200 through the gap between the hinge arm 300 and the outer panel 200, and then into the gap between the hinge arm 300 and the outer panel 200. Over time, this can cause the hinge arm 300 to absorb water and deform, further deforming the outer panel 200, affecting the vehicle's aesthetics. In severe cases, this deformation can cause unusual noises. In light of this, the present application provides a charging port cover.

[0034] See also Figures 1 to 6The charging port cover includes a base 100, an outer panel 200 and a hinge arm 300. The base 100 is fixed to the vehicle body, and an outer peripheral opening 110 is provided on the base 100. The charging port of the vehicle is provided in the outer peripheral opening 110. The outer panel 200 rotates with the base 100. The outer panel 200 is configured to cover and expose the base 100 on the vehicle body. When the charging port cover is buckled, the outer panel 200 covers the outer peripheral opening 110. When the charging port cover needs to be opened, the outer panel 200 rotates relative to the base 100, so that the outer peripheral opening 110 is exposed, and the charging gun can be inserted into the charging port through the outer peripheral opening 110. Preferably, the color of the outer panel 200 exposed outside the vehicle body is the same as the color of the vehicle body to ensure the uniformity of the vehicle body appearance. The hinge arm 300 is rotatably connected to the base 100 and fixed to the outer panel 200. The relative rotation of the hinge arm 300 and the base 100 drives the relative rotation of the outer panel 200 and the base 100, thereby realizing the opening and closing of the charging port cover. The hinge arm 300 includes a connecting portion 310, a main body 320, and a soft rubber portion 330. The connecting portion 310 is rotatably connected to the base 100. The main body 320 and the base 100 are connected by the connecting portion 310, which increases the rotation radius of the outer panel 200, avoids interference between the outer panel 200 and the vehicle body, and reduces wear and tear. The main body 320 and the connecting portion 310 are fixed, including but not limited to being fixed by an integral molding method, such as by injection molding. When the outer panel 200 covers the base 100, the main body 320 is inserted into the outer peripheral opening 110 to cover the outer peripheral opening 110. The soft rubber part 330 is arranged on the outer periphery of the main body 320 close to the outer panel 200. When the outer panel 200 covers the base 100, the soft rubber part 330 abuts against the outer side of the outer peripheral opening 110. Furthermore, the soft rubber part 330 is in interference fit against the outer side of the outer peripheral opening 110, that is, there is pressure between the soft rubber part 330 and the top wall of the outer peripheral opening 110. The soft rubber part 330 is made of elastic material and will be squeezed and deformed, thereby ensuring that the soft rubber part 330 is sealed to the outer peripheral opening 110, blocking the water flow entering through the gap between the outer panel 200 and the vehicle body, and protecting the charging port. The soft rubber part 330 is in interference fit against the outer panel 200, that is, there is pressure between the soft rubber part 330 and the outer panel 200, and the elastic soft rubber part 330 is squeezed and deformed, thereby making the soft rubber part 330 and the outer panel 200 tightly in contact. The soft rubber part 330 is arranged on the periphery of the main body 320, and the water flow entering through the gap between the outer panel 200 and the vehicle body is blocked by the soft rubber part 330, preventing the water flow from entering between the main body 320 and the outer panel 200, thereby protecting the main body 320, reducing the deformation of the main body 320 caused by washing, and extending the service life of the main body 320.A drainage groove 331 is formed between the soft rubber portion 330 and the outer panel 200, circling the main body 320. The drainage groove 331 is flanked by the soft rubber portion 330 and the outer panel 200, allowing water to flow through the gap between the outer panel 200 and the vehicle body and into the charging port cover. Typically, water flows along the outer panel 200, where it is collected in the drainage groove 331. Under the influence of gravity and other forces, the water flows from above through the drainage groove 331 to the drainage groove 331 below, and then flows out of the charging port cover, discharging the water in a timely manner to prevent water accumulation. Furthermore, the height of the middle portion of the upper drainage groove 331 is higher than the height of the two sides of the upper drainage groove 331, further facilitating water outflow. By providing the soft rubber portion 330, on the one hand, water can be prevented from contacting the main body 320, thereby preventing water from entering between the main body 320 and the outer panel 200, reducing the deformation of the main body 320 due to water absorption, thereby preventing deformation of the outer panel 200 and ensuring the appearance of the charging port cover; on the other hand, the soft rubber portion 330 can prevent water from entering the charging port, protect the charging port, prevent water from entering the charging port and causing circuit failure, and at the same time reduce water corrosion to the charging port.

[0035] In one exemplary embodiment of the charging port cover, the outer panel 200 is made of PPE plastic plus PA nylon or ABS; the main body 320 and connecting portion 310 of the hinge arm 300 are made of PA6 plus GF50 or PA66 plus GF50. In other embodiments of the present application, the outer panel 200 can be made of other materials, such as metal, and the hinge arm 300 can also be made of other materials, and this application does not limit this.

[0036] See also Figure 3 In an exemplary embodiment of the charging port cover, the soft rubber portion 330 includes a first extension 332 and a second extension 333. The first extension 332 abuts the outer panel 200 and forms a ring-shaped surface, pressing against the outer panel 200 to prevent water from flowing through. The second extension 333 abuts the outer periphery of the outer peripheral opening 110 and is also ring-shaped, its shape matching the shape of the outer peripheral opening 110. The second extension 333 has an arcuate cross-section, with its opening facing the outer peripheral opening 110. When the second extension 333 abuts the outer peripheral wall of the outer peripheral opening 110, the arc-shaped surface facing the outer peripheral opening 110 ensures that the arc-shaped edge of the second extension 333 presses against the outer peripheral wall of the outer peripheral opening 110, improving the sealing effect of the second extension 333 on the outer peripheral opening 110 and enhancing the protection of the charging port. Preferably, the first extension portion 332 , the second extension portion 333 and the outer plate 200 together form a hydrophobic groove 331 , thereby preventing water from entering the main body 320 and the charging port, thereby improving the waterproof performance.

[0037] See also Figure 3In an exemplary embodiment of the charging port cover, a raised portion 321 is formed on the outer periphery of the main body 320. The soft rubber portion 330 is injection-molded onto and covers the raised portion 321. The soft rubber portion 330 is fixed to the main body 320 through injection molding, ensuring a stable connection with the main body 320 and improving the fit between the soft rubber portion 330 and the main body 320, effectively enhancing the protection provided by the soft rubber portion 330 to the main body 320. The soft rubber portion 330 covers the raised portion 321 and forms an annular shape around the outer periphery of the main body 320, further strengthening the connection between the soft rubber portion 330 and the main body 320 and preventing separation. The soft rubber portion 330 covering the outer periphery of the main body 320 also ensures that the outer periphery of the main body 320 is not in direct contact with the outer panel 200, preventing the outer periphery of the main body 320 from being exposed to water and reducing water absorption and deformation of the main body 320.

[0038] See also Figure 5 and Figure 6 In an exemplary embodiment of the charging port cover, a plurality of snap-in portions 322 are provided on one side of the main body 320 close to the outer panel 200. A snap block 210 is provided on the outer panel 200. The snap block 210 is plugged and unplugged into the snap-in portion 322. The cooperation between the snap block 210 and the snap-in portion 322 realizes the relative fixation of the outer panel 200 and the main body 320, facilitating the installation of the outer panel 200.

[0039] See also Figure 5 and Figure 6In an exemplary embodiment of the charging port cover, the clamping portion 322 includes a first limiting plate 3221 fixed to the main body 320, and a second limiting plate 3222 arranged on the side of the first limiting plate 3221 away from the main body 320. The first limiting plate 3221 and the second limiting plate 3222 are L-shaped. When the card block 210 is inserted into the clamping portion 322, the second limiting plate 3222 can limit the card block 210 from separating from the main body 320 in a direction away from the main body 320. A plurality of clamping portions 322 are provided on the upper and lower sides of the main body 320, and second limiting plates 3222 provided on the upper and lower sides of the main body 320 extend in opposite directions. In other words, when the upper and lower clamping blocks 210 are inserted into the clamping portions 322, the upper first limiting plate 3221 limits the downward movement of the upper clamping block 210, while the lower first limiting plate 3221 limits the upward movement of the lower clamping block 210, thereby fixing the outer panel 200 relative to the main body 320 in the vertical direction. The clamping block 210 is inserted into the clamping portion 322 from the side of the clamping portion 322 away from the connecting portion 310, facilitating the engagement of the clamping block 210 with the clamping portion 322. Furthermore, the clamping portion 322 is also provided with a clamping slot, and the clamping block 210 is provided with a clamping portion. When the clamping block 210 is inserted into the clamping portion 322, the clamping block 210 or the clamping portion 322 undergoes elastic deformation until the clamping portion cooperates with the clamping slot, and the elastic deformation of the clamping block 210 or the clamping portion 322 is restored. The clamping portion cooperates with the clamping slot so that when the external force does not exceed the threshold, the outer panel 200 and the main body 320 cannot move along the direction in which the clamping block 210 is inserted into the clamping portion 322.

[0040] In an exemplary embodiment of the charging port cover, the charging port cover further includes a drive mechanism that drives the connection portion 310 to rotate, thereby driving the main body 320 and outer panel 200 to rotate, thereby opening and closing the charging port cover. The drive mechanism may include a motor and a transmission mechanism, or may be driven directly by a motor alone. Reference may be made to existing drive mechanisms for charging port covers, and this application does not limit this.

[0041] See also Figure 1 and Figure 4 In an exemplary embodiment of the charging port cover, a push switch 400 is provided on the base 100, and a push protrusion 323 is provided on the main body 320. The push protrusion 323 cooperates with the push switch 400. When the charging port cover is closed, by pressing the charging port cover, the push protrusion 323 can be abutted against the push switch 400 until the push switch 400 is triggered, and then the driving mechanism drives the connecting part 310 to rotate, thereby opening the charging port cover. The operation is convenient and simple, and the user experience is good.

[0042] See also Figure 4In an exemplary embodiment of the charging port cover, a through-hole is provided on the pressing protrusion 323, and a pressing soft glue 334 is provided in the through-hole. The pressing soft glue 334 protrudes from the through-hole on the side facing away from the outer panel 200. The pressing protrusion 323 is integrally formed with the main body 320 and has a relatively hard texture. Therefore, long-term contact between the pressing protrusion 323 and the pressing switch 400 will cause wear of the pressing switch 400, which not only affects the appearance but also easily causes damage to the pressing switch 400. By providing a through-hole on the pressing protrusion and embedding the pressing soft glue 334 in the through-hole, the elastic and soft pressing soft glue 334 contacts the pressing switch 400, which can reduce the wear of the pressing switch 400, improve the aesthetics of the surface of the pressing switch 400, and extend the service life of the pressing switch 400. Preferably, the pressing soft glue 334 has an interference fit with the through-hole, reducing the probability of the pressing soft glue 334 detaching from the through-hole and extending the service life.

[0043] In an exemplary embodiment of the charging port cover, the cross-section of the pressing soft glue 334 close to the outer panel 200 is smaller than the cross-section of the pressing soft glue 334 protruding from the main body 320. Preferably, the through hole is truncated cone-shaped, and the diameter of the through hole away from the outer panel 200 is larger than the diameter close to the outer panel 200. The pressing soft glue 334 is also truncated cone-shaped. When the pressing soft glue 334 is used for a long time, it is subjected to the force toward the outer panel 200, which prevents the pressing soft glue 334 from detaching from the through hole, thereby improving the connection stability.

[0044] See also Figure 4 In an exemplary embodiment of the charging port cover, the pressing soft adhesive 334 is integrally formed with the soft adhesive portion 330. The soft adhesive portion 330 is preferably formed by injection molding. The pressing soft adhesive 334 is formed simultaneously during the injection molding process, reducing the number of assembly steps and improving production efficiency. The interference fit between the pressing soft adhesive 334 and the through-hole further enhances the connection strength between the soft adhesive portion 330 and the main body 320. In particular, when the soft adhesive portion 330 is subjected to a force away from the outer panel 200, the force between the pressing soft adhesive 334 and the through-hole strengthens the connection strength between the soft adhesive portion 330 and the main body 320. The connection area between the soft adhesive portion 330 and the pressing soft adhesive 334 is squeezed by the outer panel 200 and the main body 320, which can also increase the difficulty of the soft adhesive portion 330 separating from the main body 320 and reduce the risk of the soft adhesive portion 330 separating from the main body 320 when subjected to external forces.

[0045] The present application also provides a vehicle, comprising any of the above-mentioned charging port covers, the charging port cover being disposed at the charging port of the vehicle body. The vehicle of the present application also includes systems or components such as a power system and a control system, which are described in detail in the present application.

[0046] The charging port cover of the present invention has the advantages of increasing the waterproof effect of the charging port cover, reducing the deformation of the main body due to water absorption, and avoiding the deformation of the outer panel that affects the appearance. At the same time, it can also provide waterproof protection for the charging port, thereby reducing the chance of damage. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and use significance. The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with this technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
