[0056] See also Figure 3-Figure 14 .

[0057] Some embodiments of the present application disclose a charging port cover, including a cover plate 1 and a frame 2.

[0058] like Figure 3-Figure 8As shown, the frame 2 is a circumferentially closed frame structure, and the frame 2 is installed on the vehicle body. Specifically, the first end of the frame 2 connected to the vehicle body and the end away from the vehicle body are the second ends, the first end and the second end are opposite, the first end of the frame 2 is the first open end, and the second end of the frame 2 is the second open end. The frame 2 is covered on the charging port 3 through the first open end, and the charging port 3 is completely located in the frame 2. The second open end of the frame 2 is provided with a cover plate 1;

[0059] The cover plate 1 is slidably matched with the second open end of the frame 2, and the shape of the frame 2 is the same as the shape of the area covered by the cover plate 1 during the sliding process, such as Figure 3-Figure 8 As shown, the cover 1 is a rectangular plate, the frame 2 is a rectangular frame, and the area enclosed by the frame 2 is larger than the projection of the cover 1 along the direction perpendicular to the vehicle body, so as to provide sufficient movement space for the cover 1 and ensure that the charging port 3 is not blocked when the cover 1 is opened.

[0060] Slideways 21 are provided on two opposite side walls of the frame 2. The slideway 21 is provided near the second open end of the frame 2. The cover plate 1 has a slide rod 11. The cover plate 1 slides with the slideway 21 of the frame 2 through the slide rod 11. The cover plate 1 slides in the frame 2 along the slideway 21.

[0061] The surface where the slideways 21 of the two oppositely arranged side walls are located is the sliding plane of the cover plate 1. The surface where the slideways 21 of the two oppositely arranged side walls are located is located near the surface where the second open end of the frame 2 is located. The cover plate 1 is always located near the surface where the second open end is located during the sliding process.

[0062] One end of the slide bar 11 extending out of the slideway 21 is connected to the linear drive assembly 4 , and the linear drive assembly 4 is installed on the frame 2 . The linear drive assembly 4 is used to drive the cover plate 1 to move so as to cover or expose the charging port 3 .

[0063] The translation of the cover plate 1 is not limited to being realized by the linear drive assembly 4, but can also be realized by manual movement.

[0064] The charging port cover disclosed in this solution has a cover plate 1 that is opened and closed by moving horizontally along the surface where the slideway 21 is arranged relatively. When the cover plate 1 moves horizontally to the position of the charging port 3, the cover plate 1 blocks the charging port 3 and the charging port 3 is closed. When the cover plate 1 moves horizontally to a position away from the charging port 3, the cover plate 1 does not block the charging port 3 and the charging port 3 is opened. At this time, charging can be performed through the charging port 3. The charging port cover disclosed in this solution changes the opening method of the cover plate 1. Compared with the flip opening method of the charging port cover in the related art, it solves the problem that the charging port cover occupies the space outside the vehicle.

[0065] After the cover 1 is opened, the cover 1 does not occupy any space above the charging port 3, and charging can be performed from all angles, thereby reducing the problem of collision between the charging port cover and the charging gun or charging cable during charging, causing inconvenience in charging.

[0066] like Fig. 9 and Fig.10 As shown, in this solution, the frame 2 of the charging port cover is located below the body sheet metal 6, and the body sheet metal 6 is provided with a hole that matches the shape of the charging port 3, and the cover plate 1 is adapted to the body shape, such as Fig. 9 As shown, when the cover plate 1 covers the charging port 3, the cover plate 1 moves along the slide 21 until it is flush with the surface of the vehicle body; Fig.10 As shown, when the cover plate 1 exposes the charging port 3 , the cover plate 1 moves along the slide 21 to be hidden under the vehicle body sheet metal 6 .

[0067] The slide 21 guides the movement of the cover 1. Optionally, the slide 21 is an inclined slide. The height of the slide 21 near the charging port 3 is higher than the height of the slide 21 away from the charging port 3, so that the cover 1 has a tendency to rise toward the second open end when sliding to the position of the charging port 3, so that the cover 1 is flush with the surface of the vehicle body when covering the charging port 3, and the cover 1 has a tendency to fall away from the second open end when sliding to a position away from the charging port 3, so that the cover 1 can be located below the vehicle body sheet metal 6 for hiding. It should be noted here that the height of the slide 21 is the distance between the slide 21 and the first open end of the frame 2.

[0068] The cover plate 1 can be a split plate or a whole plate (not shown in the figure), and the baffle is designed according to the form of the cover plate 1 .

[0069] In the embodiment where the cover plate 1 is a split plate, Figure 3-Figure 8 As shown, the cover plate 1 includes a left side plate 12 and a right side plate 13, and the left side plate 12 and the right side plate 13 move toward or away from each other under the action of the linear drive assembly 4. The left side plate 12 and the right side plate 13 move toward each other, the left side plate 12 and the rear side plate are merged together, and the charging port cover is closed; the left side plate 12 and the right side plate 13 move away from each other, the left side plate 12 and the right side plate 13 are separated, and the charging port cover is opened.

[0070] In this embodiment, the charging port 3 is located in the middle of the frame 2. Optionally, the length of the frame 2 is twice the length of the cover plate 1. It should be noted here that the length direction of the frame 2 and the length direction of the cover plate 1 are the dimensions of the frame 2 and the cover plate 1 along the sliding direction of the cover plate 1.

[0071] In an embodiment where the cover plate 1 is a whole plate, the linear drive assembly 4 drives the cover plate 1 to move. In this embodiment, the charging port 3 is located on one side of the length direction of the frame 2. Optionally, the length of the frame 2 is twice the length of the cover plate 1. It should be noted here that the length direction of the frame 2 and the length direction of the cover plate 1 are the dimensions of the frame 2 and the cover plate 1 along the sliding direction of the cover plate 1.

[0072] When the cover plate 1 moves to the end of the frame 2 where the charging port 3 is provided, the charging port cover is closed, and when the cover plate 1 moves to the end of the frame 2 where the charging port 3 is not provided, the charging port cover is opened.

[0073] In an embodiment in which the cover plate 1 includes a left side plate 12 and a right side plate 13, a linear drive assembly 4 for driving the left side plate 12 and the right side plate 13 to move includes a first motor 41, a first driving gear 42, a first driven gear 43, a first driving wheel 44, a first driven wheel 45, a second driven wheel 46, a first track 47 and a second track 48.

[0074] Specifically, the first motor 41 is connected to the first driving gear 42 to drive the first driving gear 42 to rotate;

[0075] The first driving gear 42 is meshed with the first driven gear 43, and the first driving gear 42 drives the first driven gear 43 to rotate;

[0076] The first driving wheel 44 is connected to the output shaft of the first driven gear 43, and the first driven gear 43 drives the first driving wheel 44 to rotate;

[0077] The first driving wheel 44 is connected to the first driven wheel 45 through the first crawler 47, the first driving gear 42 is connected to the second driven wheel 46 through the second crawler 48, the first driving wheel 44 and the first driven wheel 45 cooperate to drive the first crawler 47, and the first driving wheel 44 and the second driven wheel 46 cooperate to drive the second crawler 48.

[0078] In order to achieve opposite movement directions of the left plate 12 and the right plate 13 , the upper side of the first crawler 47 is connected to the slide bar 11 of the left plate 12 , and the lower side of the second crawler 48 is connected to the slide bar 11 of the right plate 13 .

[0079] During operation, the first motor 41 drives the first driving gear 42 to rotate, the first driving gear 42 drives the first driven gear 43 to rotate, the first driven gear 43 drives the first driving wheel 44 to rotate, and the first driving wheel 44 simultaneously drives the first crawler belt 47 and the second crawler belt 48 to transmit, thereby realizing the left side plate 12 and the right side plate 13 to move toward or away from each other.

[0080] This solution realizes the opening of the left side plate 12 and the right side plate 13 through a single motor + group processing linkage, ensuring that the operating time is shortened while achieving the same function and the same speed movement.

[0081] In some embodiments, the sliding rod 11 of the left side plate 12 is connected to the first track 47 by a snap-fit ​​connection, and the sliding rod 11 of the right side plate 13 is connected to the second track 48 by a snap-fit ​​connection, so that the sliding rod 11 of the left side plate 12 and the sliding rod 11 of the right side plate 13 are fixedly connected to the first track 47 and the second track 48 respectively, ensuring the stability and reliability of the first track 47 and the second track 48 driving the movement of the left side plate 12 and the right side plate 13 respectively.

[0082] In some embodiments, the specific structure of the linear drive assembly 4 includes a motor, a driving wheel, a driven wheel and a crawler track, the motor is connected to the driving wheel, the driving wheel and the driven wheel are connected through the crawler track, and the left side plate 12 and the right side plate 13 are respectively connected to the upper side and the lower side of the crawler track. When the motor drives the crawler track to rotate in a first direction, the left side plate 12 and the right side plate 13 move toward each other, and when the motor drives the crawler track to move in a second direction, the left side plate 12 and the right side plate 13 move away from each other, wherein the first direction and the second direction are opposite.

[0083] In the above two embodiments, the left plate 12 and the right plate 13 are synchronously driven by a first motor 41, which saves the number of first motors 41 used and reduces the overall volume of the linear drive assembly 4. At the same time, the movement stroke is short, the movement process is smooth and synchronous, and the cost is low.

[0084] In some embodiments, the linear drive assembly 4 is a telescopic cylinder or a screw assembly or other linear drive assembly 4 .

[0085] In the embodiment where the cover plate 1 is a split structure, the left side plate 12 and the right side plate 13 may share the slideway 21 , or may have their own slideways 21 .

[0086] Preferably, the left side plate 12 and the right side plate 13 have respective slideways 21, and the slideway 21 of the left side plate 12 is not connected to the slideway 21 of the right side plate 13. The slideway 21 can limit the movement of the left side plate 12 and the right side plate 13, thereby improving the reliability of the charging port cover.

[0087] In some embodiments, the left side plate 12 and the right side plate 13 have two slide bars 11 at one end thereof that cooperate with the slideway 21, so as to improve the stability of the left side plate 12 and the right side plate 13 sliding in the slideway 21. Optionally, each slide bar 11 has its own slideway 21. Figure 7 As shown in the example, four slide rails 21 are provided on one side of the frame, and the four slide rails 21 are slidably matched with the four slide bars 11 of the left side plate 12 and the right side plate 13 respectively.

[0088] like Figure 7As shown, the slide 21 is a curved slide, including a first slide 211 and a second slide 212. The first slide 211 is closer to the charging port 3 than the second slide 212. The height of the first slide 211 is higher than the height of the second slide 212. The first slide 211 and the second slide 212 have a smooth transition. The first slide 211 is an inclined slide. When the cover slides along the second slide 212, the cover 1 moves below the body sheet metal 6. When the cover 1 slides into the first slide 211, the cover 1 enters the opening of the body sheet metal 6 corresponding to the charging port 3. When the cover 1 slides to the end of the first slide 211, the cover 1 covers the charging port 3 and is flush with the body sheet metal 6.

[0089] In an embodiment where the charging port 3 is disposed at one end of the frame 2 along the sliding direction of the cover plate 1 , the linear drive assembly 4 may be a lead screw assembly, a telescopic cylinder or other linear drive assembly 4 .

[0090] In some embodiments, the linear drive assembly 4 includes a second motor, a second driving gear, a second driven gear, a second driving wheel, a third driven wheel and a third crawler. Specifically,

[0091] The second motor is connected to the second driving gear, the second driving gear is meshed with the second driven gear, the second driven gear is connected to the second driving wheel through the output shaft, and the second driving wheel is connected to the third driven wheel through the third crawler.

[0092] During operation, the second motor electrically drives the second driving gear to rotate, the second driving gear drives the second driven gear to rotate, the second driven gear drives the second driving wheel to rotate, and the second driving wheel cooperates with the third driven wheel to drive the third crawler track to move.

[0093] The slide bar 11 of the cover plate 1 is fixedly connected to the third crawler belt, so that the third crawler belt drives the cover plate 1 to move.

[0094] In some embodiments, the slide bar 11 is fixedly connected to the third track via a buckle.

[0095] like Figure 6 As shown, a micro switch 5 is provided on the frame 2 for controlling the start and stop of the motor.

[0096] In this solution, the linear drive assembly 4 can be connected to at least one of the central control and the key for communication, so that the user can remotely control the opening and closing of the charging port cover, replacing the manual opening method in the related art, thereby improving the convenience of opening the charging port cover.

[0097] In some embodiments, a voice switch is provided on the linear drive assembly 4 to realize voice control of opening and closing of the charging port cover, so that the user can open and close the charging port cover outside the vehicle and without a key.

[0098] The charging port cover disclosed in the present solution occupies less internal space through the translation of the cover plate 1, thereby reducing the demand for internal layout space and being suitable for small space layout requirements such as fenders.

[0099] The linear drive assembly 4 can be arranged inside the frame 2 or outside the frame 2 .

[0100] The frame 2 can be designed according to the shape requirements to meet the needs of diversified shapes, and the shape sealing positions are changeable, which can meet various surface requirements and realize the design of multi-shape and multi-curved cover 1.

[0101] The present solution also discloses a car, comprising a charging port cover, wherein the charging port cover is the charging port cover recorded in any one of the above solutions.

[0102] Since the charging port cover has the above-mentioned technical effects, the car with the charging port cover also has the same technical effects, which will not be repeated here.

[0103] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used, and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. The scope of application involved in the present application is not limited to the technical solution formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned application concept.
