Description

Technical Field

[0001] The present invention relates to the field of electric vehicles, and in particular to a charging port cover assembly for an electric vehicle. In addition, the present invention relates to an electric vehicle having such a charging port cover assembly. Background Art

[0002] With the development of electric vehicles, the intelligence and convenience of electric vehicles have also been further developed.

[0003] Typically, a charging port is provided in the body of an electric vehicle and a charging cover is provided at a position of the body corresponding to the charging port. When the electric vehicle needs to be charged, the charging cover can be opened manually by a user or automatically by a vehicle controller with the aid of a motor for driving the charging cover, so that the charging port is exposed to the external environment and the charging gun can be engaged with the charging port in a manner capable of transmitting electrical energy, so as to realize charging of the power battery of the electric vehicle.

[0004] In order to protect the charging port from external environmental factors such as rain and dust, the charging cover is usually constructed in two pieces and includes an outer cover and an inner cover. The outer cover can be opened automatically or by an automatic charging robot. The inner cover can usually only be opened or removed manually by the user. Especially when using an automatic charging robot for charging, although the outer cover can be opened and closed automatically, the user still needs to get off the vehicle to open and close the inner cover manually. This affects the user experience when charging an electric vehicle.

[0005] In addition, in a charging cover in the prior art, an electric drive unit is provided for the inner cover, and the electric drive unit can automatically open / close the inner cover in a controlled manner without user operation. However, this charging cover needs to be additionally equipped with a corresponding drive structure. This not only increases the manufacturing and assembly costs, but also increases the space occupied at the charging port. In addition, due to the complex structure and increased components, this also increases the failure rate of the charging cover.

[0006] Furthermore, there is a risk of insufficient sealing in the charging cover in the prior art.

[0007] Therefore, there is still a need for improvement in the prior art to address at least some of the above issues. Summary of the invention

[0008] Based on this, the present invention proposes an efficient solution, which can not only overcome the deficiencies in the existing technical solutions, but also further promote the intelligent development of electric vehicles and further improve user satisfaction.

[0009] According to a first aspect of the present invention, there is provided a charging port cover assembly for an electric vehicle, wherein the charging port cover assembly is arranged on a body of the electric vehicle, wherein the charging port cover assembly comprises:

[0011] at least one charging port, the charging port being arranged in the vehicle body opening and being configured to be electrically connected to a charging device to enable charging of the electric vehicle; and

[0012] at least one sealing portion, the sealing portion being configured to close the charging port;

[0013] The sealing portion is arranged on the inner side of the outer cover in a suspended manner and is configured to automatically release the charging port as the outer cover is opened and automatically close the charging port as the outer cover is closed.

[0014] The basic concept of the present invention is that, by providing a sealing portion suspended and connected to the inner side of the outer cover of the charging port cover assembly, the sealing portion can automatically close or release the charging port as the outer cover moves in a closing or opening manner. This not only avoids the need for the driver to get off the vehicle and manually open the inner cover or release the charging port after the outer cover is automatically opened, thereby further improving the driver's driving experience and charging convenience, but also, due to the sealing portion, the protection of the charging port is reliably further improved, thereby further improving charging and driving safety.

[0067] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the scope of protection of the present invention.

[0068] In this specification, for the sake of convenience, the words and phrases indicating the orientation or positional relationship such as "middle", "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like are used to illustrate the positional relationship of the constituent elements with reference to the drawings. This is only for the convenience of describing this specification and simplifying the description, and does not indicate or imply that the device or element referred to has a specific orientation, is constructed and operates in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. The positional relationship of the constituent elements is appropriately changed according to the direction of describing each constituent element. Therefore, it is not limited to the words and phrases described in the specification, and can be appropriately replaced according to the situation.

[0069] Figure 1 A schematic diagram of an embodiment of a vehicle 1 according to the invention is shown.

[0070] In this embodiment, the vehicle 1 is exemplarily a passenger car and is configured as a pure electric vehicle. However, in other embodiments, the vehicle 1 may also be a commercial vehicle, such as a truck or a bus, and be configured as a hybrid vehicle.

[0071] A body opening 11 is formed in the rear region of the vehicle 1 on the side of the body, and a charging flap assembly 2 is arranged at the body opening 11. The vehicle 1 is charged by means of the charging flap assembly 2 via a corresponding charging device, such as a charging gun, for example, of a charging station.

[0072] Figure 2 A schematic diagram of an embodiment of a charging port cover assembly 2 of the present invention is shown.

[0073] like Figure 2 As shown, the charging port cover assembly 2 includes an outer cover 21, which is used to close the vehicle body opening 11 for charging. The outer cover 21 is made of the same material as the vehicle body, for example, a steel plate or an aluminum alloy plate.

[0074] In addition, the charging port cover assembly 2 includes at least one charging port 22. In this embodiment, the charging port cover assembly 2 includes a charging port 22, which is arranged in the vehicle body opening 11 and is configured to be electrically connected to a charging device to charge the electric vehicle 1. Exemplarily, the charging port 22 is configured as a DC charging port, which can allow a charging power of more than 15kw, for example.

[0075] According to this embodiment, the charging port cover assembly 2 also includes at least one sealing portion 23. The sealing portion 23 is used to seal the charging port 22 in a fluid-tight, especially airtight manner. The sealing portion 23 is arranged on the inner side of the outer cover 21 in a suspended manner and can automatically release the charging port 22 as the outer cover 21 is opened and automatically close the charging port 22 as the outer cover 21 is closed. Thus, through such arrangement and connection of the sealing portion 23 and the outer cover 21, the driver does not have to get off the vehicle to manually open or close the charging port 22 before automatically opening or automatically closing the outer cover 21, which not only improves convenience and user experience, but also ensures the anti-loss connection and reliable sealing of the sealing portion 23 through this embodiment.

[0076] In the present invention, “the sealing portion 23 is arranged inside the outer cover 21 in a suspended manner” should be understood as the sealing portion 23 and the outer cover 21 are non-rigidly connected to each other and the sealing portion 23 is displaceably arranged relative to the outer cover 21 .

[0077] In the present invention, the “inner side of the outer cover 21 ” refers to the vehicle 1 or the vehicle body 1 relative to the surrounding environment. The inner side should be understood as the end side of the outer cover 21 facing the charging port 22 when the outer cover 21 closes the vehicle body opening 11 .

[0078] In this embodiment, the sealing portion 23 is connected to the inner side of the outer cover 21 by means of an elastic connection portion 24, which is exemplarily configured as an elastic cord, for example, made of nylon. Alternatively, the elastic connection portion 24 can also be configured as a spring or an elastomer. Therefore, a "spring-type" connection is achieved between the sealing portion 23 and the outer cover 21.

[0079] The sealing portion 23 includes a sealing body 231 and a first coupling element 232 arranged on the sealing body 231. Accordingly, a second coupling element 221 is arranged on the charging port 22. The first coupling element 232 can be coupled to the second coupling element 221 in a force-locking manner to close the charging port 22.

[0080] The sealing body 231 is made of, for example, plastic, such as PTFE, or of rubber, thereby achieving simple and cost-effective production.

[0081] Also like Figure 2 As shown, the outer cover 21 is pivotably movable relative to the body opening 11 via a hinge 25 and thus enables simple and functionally reliable opening or closing of the body opening 11 .

[0082] According to another embodiment, a seal (not shown), such as a rubber seal strip, is arranged on the inner edge of the outer cover 21, and the seal seals the vehicle body opening 11 from the surrounding fluid when the outer cover 21 closes the vehicle body opening 11. Thus, the sealing effect of the charging port cover assembly 2 is further improved.

[0083] Next, combine Figures 3 to 5 And also refer to Figure 1 and Figure 2 Embodiments of the present invention are further described.

[0084] Figure 3 Shows Figure 2 A schematic stereoscopic view of an embodiment of the sealing portion 23 of the charging port cover assembly 2. Figure 4a Shows Figure 3 Schematic three-dimensional view of the sealing body 231 of the sealing portion 23 in FIG. Figure 4b Shows Figure 4a Schematic cross-sectional view AA of the sealing body 231 in FIG. Figure 5 Shows Figure 3 Schematic diagram of the first coupling element 232 of the charging port cover assembly 2.

[0085] In this exemplary embodiment, the first coupling element 232 of the seal 23 is arranged or pre-assembled on the sealing body 231 .

[0086] like Figure 3 and Figure 4a As shown, the sealing body 231 has a cylindrical shape and has a flange 233 in a direction toward the charging port 22 . That is, the flange 233 extends from the sealing body 231 in a direction toward the charging port 22 .

[0087] The first coupling element 232 is designed in an annular shape (see also Figure 5 ) and can be sleeved on the flange 233. The width of the flange 233 along the axial direction of the sealing body 231 is configured to be at least not less than the width of the first coupling element 232 along the axial direction of the sealing body 231. In other words, the width of the first coupling element 232 along the axial direction of the sealing body 231 is configured to be at least not greater than the width of the flange 233 along the axial direction of the sealing body 231.

[0088] Therefore, when the first coupling element 232 is sleeved on the flange 233 , the end surface of the first coupling element 232 in the direction toward the charging port 22 does not exceed the end surface of the flange 233 .

[0089] The flange 233 has the same material as the sealing body 231, or the flange 233 is integrally constructed with the sealing body 231. Due to the material properties of the flange 233 or the sealing body 231, the outer peripheral size of the flange 233 can be constructed to be slightly larger than the inner peripheral size (inner diameter) of the ring of the first coupling element 232. When the first coupling element 232 is sleeved on the flange 233, the first coupling element 232 can be reliably fixed on the flange 233 or the sealing body 231 through interference fit.

[0090] Corresponding to the sealing portion 23, the charging port 22 is configured as a circular recess, in which corresponding electrical connection terminals and signal terminals are arranged. Figure 2 Corresponding to the first coupling element 232 , the second coupling element 221 is also designed in an annular shape and is arranged at the edge of the charging port 22 in the circumferential direction of the charging port 22 .

[0091] Alternatively, the first coupling element 232 may also be integrally or one-piece constructed with the sealing body 231 , thereby reducing assembly work.

[0092] According to this embodiment, the first coupling element 232 and the second coupling element 221 are coupled to each other in a magnetically attracted manner and are constructed in the same structure. The first coupling element 232 is constructed as a first permanent magnet, which has a first polarity, such as an N pole, and the second coupling element 221 is constructed as a second permanent magnet and has a second polarity opposite to the first polarity of the first permanent magnet, such as an S pole. Alternatively, the second coupling element 221 is constructed as a metal element that can be attracted by the first permanent magnet, such as an iron element. As a result, the manufacturing cost is reduced.

[0093] Of course, it is also conceivable that the second coupling element 221 is configured as a second permanent magnet, and the first coupling element 232 is configured as a metal element that can be attracted by the second permanent magnet, such as an iron element. Thus, the first coupling element 232 and the second coupling element 221 can also be magnetically attracted to each other.

[0094] In another embodiment not shown, the first coupling element 232 is constructed as an electromagnet and is configured to generate magnetism when energized, and the second coupling element 221 is constructed as a metal element that can be attracted by the first permanent magnet, such as an iron element. Of course, it is also conceivable that the second coupling element 221 is constructed as an electromagnet and is configured to generate magnetism when energized, and the first coupling element 232 is constructed as a metal element that can be attracted by the second permanent magnet, such as an iron element.

[0095] According to this embodiment, the second coupling element 221 is fixed on the edge of the charging port 22 so as to protrude from the opening plane of the charging port 22. Alternatively, the second coupling element 221 is embedded in the edge of the charging port 22 flush with the opening plane of the charging port 22, thereby reducing the depth of the charging port 22 and improving the aesthetics. Therefore, accordingly, a receiving groove that matches the shape of the second coupling element 221 is constructed in the edge.

[0096] like Figure 3 As shown, the width of the first coupling element 232 along the axial direction of the sealing body 231 is configured to be slightly smaller than the width of the flange 233 along the axial direction of the sealing body 231. Therefore, after the first coupling element 232 is sleeved on the flange 233, the end surface of the flange 233 slightly exceeds the end surface of the first coupling element 232 facing the charging port 22 along the axial direction of the sealing body 231.

[0097] Therefore, when the first coupling element 232 is forcefully coupled to the second coupling element 221, the flange 233 can be at least partially squeezed into the charging port 22 due to its material and the size relationship of its outer periphery relative to the inner diameter of the charging port 22. In this way, the flange 233 abuts against the inner periphery of the charging port 22 in a fluid-tight manner, especially in an airtight manner, which realizes an interference fit between the flange 233 and the charging port 22 and advantageously ensures the sealing of the charging port 22.

[0098] Figure 6 A schematic side view of the charging port cover assembly 2 of the present invention when closed is shown.

[0099] like Figure 6 See also Figure 2 After charging is completed, the outer cover 21 is automatically pivoted toward the vehicle body opening 11 by the driver's input control and finally closes the vehicle body opening 11. As the outer cover 21 moves toward the vehicle body opening 11 or toward the charging port 22, the sealing portion 23 connected to the outer cover 21 through the elastic connection portion 24 also moves toward the charging port 22 accordingly.

[0100] Therefore, the first coupling element 232 of the sealing portion 23, which is configured as a permanent magnet, for example, moves toward the second coupling element 221 (currently, for example, an iron element) arranged at the edge of the charging port 22, and as the distance between the first coupling element 232 and the second coupling element 221 becomes closer, the magnetic attraction of the first coupling element 232 (permanent magnet) to the second coupling element 221 (iron element) becomes greater and greater, so that finally, when the outer cover 21 closes the vehicle body opening 11, the first coupling element 232 is magnetically coupled with the second coupling element 221 (such as Figure 6 ) and the flange 233 is partially inserted into the charging port 22 (see also Figure 3), thereby achieving that the sealing portion 23 automatically closes the charging port 22 in a fluid-tight manner during the process of the outer cover 21 automatically closing the vehicle body opening 11.

[0101] In this embodiment, the length of the elastic connection portion 24 is configured so that when the sealing portion 23 closes the charging port 22, the elastic connection portion 24 does not generate elastic tension between the sealing portion 23 and the outer cover 21. Without generating elastic tension, a smaller or thinner first coupling element 232 (permanent magnet) can provide sufficient magnetic attraction to reliably magnetically couple it with the second coupling element 221.

[0102] In addition, the length of the elastic connection portion 24 is configured so that at least when the outer cover 21 is fully opened (see, for example, Figure 2 ) The elastic tension of the elastic connecting portion 24 enables the sealing portion 23 to automatically release the charging port 22.

[0103] The length or elastic deformation amount of the elastic connection part 24 should, on the one hand, be sufficient to ensure that when the outer cover 21 closes the vehicle body opening 11, at least the sealing part 23 can hermetically seal the charging port 22; and on the other hand, when the outer cover 21 is fully opened, the elastic deformation force (tensile force) of the elastic connection part 24 can overcome the coupling force (magnetic force) between the first coupling element 232 and the second coupling element 221 and reliably realize the automatic release of the sealing part 23 to the charging port 22.

[0104] Figure 7 FIG. 2 is a schematic diagram showing another embodiment of the charging port cover assembly 2 of the present invention. Figure 2 The difference between the embodiment in the embodiment is that the charging port cover assembly 2 includes two charging ports 22 and two corresponding sealing parts 23 in addition to an outer cover 21. One of the two charging ports 22 is configured as a DC charging port 223, and the other charging port is configured as an AC charging port 222. The two sealing parts 23 are connected to the inner side of the outer cover 21 in a suspended manner through the elastic connecting part 24, and the corresponding charging port 22 is automatically released as the outer cover 21 is opened, and the corresponding charging port 22 is automatically closed as the outer cover 21 is closed. Thus, the user is provided with the possibility of multiple charging methods.

[0105] Through the technical solution and different embodiments of the present invention, the user does not have to get off the vehicle and manually release the charging port 22 for charging, which not only simplifies the user's operation and improves the operating comfort and convenience, but also provides a technical possibility for automatic charging without the driver getting off the vehicle at an automatic charging station (in an automatic charging station, the corresponding charging device, such as a charging gun, can automatically align with the charging port when the vehicle is in a specified position and the charging port is opened).

[0106] Other advantages and alternative embodiments of the present invention are obvious to those skilled in the art. Therefore, the present invention in its broader sense is not limited to the specific details, representative structures and exemplary embodiments shown and described. On the contrary, those skilled in the art can make various modifications and substitutions without departing from the basic spirit and scope of the present invention.
