These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In order to make the technical solutions and advantages of the present application clearer, the charging port opening and closing device and the vehicle will be described in detail in combination with the drawings.

[0047] Electric vehicles use electricity as a power source, and charge the battery in the vehicle body through the charging port. Usually, a charging port is opened on the body of the vehicle, and a cover that can close the charging port is set at the charging port. One side of the cover is hinged to the shell of the vehicle, and the cover can lock or unlock the charging port. At present, the cover on some vehicles requires the user to manually press to pop up or close, which is inconvenient to use. Moreover, this type of flip-out cover is also very susceptible to damage by external impact. In addition, because this type of cover needs to leave space for the cover to flip out, a certain gap needs to be reserved between the cover and the body shell, which is neither beautiful nor conducive to sealing.

[0048] In order to solve the above problems, the present application provides a charging port opening and closing device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the charging port opening and closing device may include a shell 1, an opening and closing mechanism 2 and a cover plate 3; a charging port 11 is opened on the shell 1, the shape of the cover plate 3 is adapted to the shape of the charging port 11, and the opening and closing mechanism 2 is arranged inside the shell 1; wherein, the opening and closing mechanism 2 includes a gear 21 and a rack 22, the gear 21 is meshed with the rack 22, the rack 22 is connected to the cover plate 3, and can drive the cover plate 3 to open or close the charging port 11 under the drive of the gear 21.

[0049] In the charging port opening and closing device provided in the embodiment of the present application, the gear 21 and the rack 22 cooperate to drive the cover plate 3 to open or close the charging port 11, so that the cover plate 3 can move relatively smoothly and controllably. It has a simple structure and low cost, which helps to achieve automatic control.

[0050] In addition, since the opening and closing mechanism 2 is arranged inside the shell 1, when the cover plate 3 closes the charging port 11, the opening and closing mechanism 2 is protected inside the shell 1 and is not affected by external interference and erosion such as dust and rain, thereby reducing the possibility of obstruction in the cooperation between the gear 21 and the rack 22, improving the reliability of the opening and closing mechanism 2, and helping to increase the service life of the opening and closing mechanism 2.

[0051] In some embodiments, the housing 1 may be a part of the vehicle shell, and the side of the housing 1 facing the inner cabin of the vehicle is regarded as the inner side of the housing 1, and the side of the housing 1 facing the outside is regarded as the outer side of the housing 1. The housing 1 is provided with a charging port 11, and the charging socket of the vehicle can be exposed to the outside through the charging port 11. The charging port 11 can be configured in a rectangular or circular shape, and those skilled in the art can select and adjust the shape, size, and setting position of the charging port 11 according to actual needs.

[0052] A cover plate 3 is provided at the charging port 11, and the shape of the cover plate 3 is consistent with the shape of the charging port 11. The cover plate 3 can be covered on the charging port 11 and close the charging port 11. An opening and closing mechanism 2 is provided on the inner side of the housing 1, and the opening and closing mechanism 2 is connected to the cover plate 3. The cover plate 3 can close or open the charging port 11 under the drive of the opening and closing mechanism 2.

[0053] Specifically, the opening and closing mechanism 2 may include a gear 21 and a rack 22. The gear 21 and the rack 22 are both disposed on the inner side of the housing 1. The gear 21 meshes with the rack 22. When the gear 21 rotates, the rack 22 is driven to move linearly. The rack 22 is connected to the cover plate 3, thereby driving the cover plate 3 to move relative to the charging port 11. Driven by the rack 22, the cover plate 3 can move closer to the charging port 11 to close the charging port 11, and can also move away from the charging port 11 and be stored back into the housing 1.

[0054] In some embodiments of the present application, Figure 4 The housing 1 is provided with a first slide groove 12 on at least one inner side wall on two opposite sides in the first direction; the opening and closing mechanism 2 further includes a transmission assembly 23, the transmission assembly 23 is fixedly connected to the rack 22, and is slidably connected to the first slide groove 12, and the transmission assembly 23 is also connected to the cover plate 3. The first direction is perpendicular to the extension direction of the first slide groove 12.

[0055] Specifically, both sides of the first direction of the shell 1 have inwardly concave side surfaces, and the concave portion forms a first slide groove 12. The gear 21 and the rack are arranged on the same side surface. When the transmission assembly 23 moves along the extension direction of the first slide groove 12, it can drive the cover plate 3 to move, thereby opening or closing the charging port 11.

[0056] Optionally, the opening and closing mechanism 2 may include two gears 21 and two racks 22 , and the gears 21 and the racks 22 are provided on the two inner side surfaces in the first direction.

[0057] Thus, the transmission assembly 23 can move relatively smoothly along the first sliding groove 12, so that the rack drives the cover plate 3 to move relatively smoothly.

[0058] Among them, the opening and closing mechanism 2 drives the cover plate 3 to open and close in different ways. In one example, the first slide groove 12 may include a first slot section 121 and a second slot section 122 that intersect each other, and the transmission component 23 can slide along the extension direction of the first slot section 121 and drive the cover plate 3 to move in the direction of the opening of the charging port 11 toward or away from the charging port 11, and the transmission component 23 can move along the extension direction of the second slot section 122 and drive the cover plate 3 to move in the second direction toward or away from the charging port 11.

[0059] In this arrangement, when the charging port 11 needs to be opened, the cover plate 3 can be first driven by the transmission assembly 23 to move in the direction away from the charging port 11 (specifically, it can be toward the inner side of the above-mentioned housing 1) in the opening direction of the charging port 11. After the cover plate 3 is moved to the inner side of the housing 1 as a whole, the cover plate is driven by the transmission assembly 23 to move along the extension direction of the second slot section 122 (specifically, it can be above, below or to the side of the charging port 11, and it does not block the charging socket after moving), so that the cover plate 3 can be hidden inside the housing 1, that is, inside the vehicle, and the cover plate 3 is hidden. Compared with the vehicles using manual or flip-out charging covers in the related art, it is more convenient to use, and the user can operate it inside the vehicle. In addition, there is no need to reserve space outside the vehicle, which avoids scratches, damage, etc. that may occur when the charging cover is flipped outward, and the inner wall of the charging cover will not be affected by the external environment (wind, snow, rain, dust, etc.). When the charging port 11 needs to be closed, the reverse operation is sufficient. The principle is the same and will not be elaborated here.

[0060] In addition, the overall shape of the charging guns on most of the current charging piles is cylindrical, but with the increasing demand for automated charging, attempts have been made to use robotic arms to connect and control the charging guns for automated charging.

[0061] Compared with the outward-folding cover in the related art, the hidden storage cover 3 does not need to occupy external space and will not block the charging port 11 on the side. The shape requirements of the robot arm, as well as the amount of calculation when operating charging and avoiding obstacles can be reduced.

[0062] In another example, the first slide groove 12 may include an intersecting first groove section 121 and a second groove section 122, the transmission component 23 can slide along the extension direction of the first groove section 121, and drive the cover plate 3 to flip toward the inside or outside of the shell 1, and the transmission component 23 can move along the extension direction of the second groove section 122, and drive the cover plate 3 to move in a second direction toward or away from the charging port 11, and the second direction is perpendicular to the first direction.

[0063] In this setting mode, when it is necessary to open the charging port 11, the cover plate 3 can be driven by the transmission assembly 23 to flip toward the inside of the housing 1 (i.e., the inside of the vehicle). When the cover plate 3 flips to the extreme position, the transmission assembly 23 can drive the cover plate 3 to move along the second direction (specifically, it can be moved toward the inside of the vehicle, and it does not block the charging socket after moving), and then the cover plate 3 can be hidden inside the housing 1, that is, inside the vehicle, realizing the hidden storage of the cover plate 3. Compared with the vehicles using manual or flip-out charging covers in the related art, it is more convenient to use, and the user can operate it inside the vehicle. In addition, there is no need to reserve space outside the vehicle, which avoids scratches, damage, etc. that may occur when the charging cover is flipped outward, and the inner wall of the charging cover will not be affected by the external environment (wind, snow, rain, dust, etc.). When it is necessary to close the charging port 11, the reverse operation can be performed. The principle is the same and will not be described in detail here.

[0064] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the extension direction of the first slot segment 121 intersects with the extension direction of the second slot segment 122 ; wherein the first slot segment 121 is parallel to the direction of gravity, and the second slot segment 122 is inclined so as to be further away from the first slot segment 121 as it is further away from the charging port 11 .

[0065] In this arrangement, when the charging port 11 needs to be opened, the cover plate 3 can be first driven by the transmission assembly 23 to flip toward the inside of the housing 1 (i.e., the inside of the vehicle). When the cover plate 3 flips to the extreme position, the transmission assembly 23 can drive the cover plate 3 to move obliquely upward (specifically, it can be the extension direction of the second slot section 122), so that the cover plate 3 can be hidden inside the housing 1, that is, inside the vehicle, and the cover plate 3 can be hidden. Those skilled in the art can select and adjust the intersection angle between the first slot section 121 and the second slot section 122 according to actual needs, so as to achieve the storage of the cover plate 3.

[0066] In some embodiments of the present application, Figure 5As shown, the transmission assembly 23 includes a first transmission member 231, a rotating member 232 and a second transmission member 233; the first transmission member 231 is slidably connected to the first slot section 121, and is rotatably connected to the first end of the rotating member 232, the second end of the rotating member 232 is rotatably connected to the cover plate 3, the first end is opposite to the second end, and the angle between the first end and the second end remains fixed after rotating to the extreme position; the second transmission member 233 is fixedly connected to the rack 22, is slidably disposed in the second slot section 122, and is connected to the first transmission member 231.

[0067] The cover plate 3 is connected to the rotating member 232. The rotating member 232 has a first end and a second end located at both ends. The first end of the rotating member 232 is rotatably connected to the first transmission member 231, and the first transmission member 231 is slidably connected to the first slot section 121. The second end of the rotating member 232 is hinged to the second transmission member 233, and the second transmission member 233 is slidably connected to the second slot section 122.

[0068] When the charging port 11 is opened, the gear 21 rotates in one direction and drives the rack 22 to move the second transmission member 233 in the second direction. The second transmission member 233 drives the rotating member 232 away from the charging port 11, and at the same time drives the first transmission member 231 to slide along the first slot section 121. The distance that the first transmission member 231 slides in the first slot section 121 is consistent with the distance that the second transmission member 233 slides along the second slot section 122. During the sliding process, the rotating member 232 gradually flips from being parallel to the first slot section 121 to being approximately parallel to the second slot section 122, so that the cover plate 3 moves away from and opens the charging port 11. To close the charging port 11, the reverse operation is sufficient. The principle is the same and will not be elaborated on here.

[0069] Since the two sides of the rotating member 232 are respectively hinged to the first transmission member 231 and the second transmission member 233, when the first transmission member 231 and the second transmission member 233 slide respectively, the cover plate 3 is driven to flip and the cover plate 3 is driven to move upward as a whole. When the cover plate 3 is flipped to an angle parallel to the second groove section 122, the cover plate 3 as a whole has been received inside the shell 1, thereby realizing the opening of the cover plate 3 to the charging port 11.

[0070] In some embodiments of the present application, the opening and closing mechanism 2 also includes a first adapter 24 and a second adapter 25, the first adapter 24 is located inside the shell 1, and the cover plate 3 is embedded in the first adapter 24 and is rotatably connected to the second adapter 25, and the second adapter 25 is connected to the second transmission member 233; the charging port opening and closing device also includes a base 4, the base 4 is located inside the shell 1, the first adapter 24 and the second adapter 25 are both located on the side of the base 4 facing the charging port 11, and can move relative to the base 4.

[0071] The charging port opening and closing device also includes a base 4, which is located inside the shell 1, and a receiving space is formed between the base 4 and the shell 1. A first adapter 24 is provided on the side of the base 4 facing the charging port 11, and the cover plate 3 is embedded in the first adapter 24. The transmission assembly 23 can indirectly drive the cover plate 3 to move through the first adapter 24. Since the cover plate 3 is embedded in the first adapter 24, it is easier to achieve waterproofing and sealing through the first adapter 24, and the first adapter 24 will not cause wear to the cover plate 3 when it moves. The first adapter 24 is provided at the second end of the rotating member 232, and the second adapter 25 is connected to the rack 22 through the second transmission member 233. The second adapter 25 can be connected to the second transmission member 233 through an axis. When the rack 22 moves, it can simultaneously drive the second transmission member 233 and the second adapter 25 to move along the second direction.

[0072] Specifically, when the charging port 11 needs to be opened, the gear 21 and the rack 22 drive the second adapter 25, and the second adapter 25 moves relative to the base along the extension direction of the second slot section 122, while driving the first adapter 24 to move. Since a rotating member 232 is provided between the cover plate 3 and the first adapter 24, when the cover plate 3 moves upward along the extension direction of the first slot section 121, the upper part of the cover plate 3 will flip toward the inner side of the shell 1, that is, the interior of the vehicle. When the first adapter 24 moves to the end of the first slot section 121 above the gravity direction, the cover plate will rotate to a position parallel to the extension direction of the second slot section 122, and the cover plate 3 as a whole is also located inside the shell 1, ultimately realizing the hidden storage of the cover plate 3.

[0073] In some embodiments of the present application, Figure 7 As shown, the charging port opening and closing device also includes a base 4, which is located inside the shell 1, and the surface of the base 4 facing the charging port 11 includes a first surface 41 and a second surface 42 that are connected, the first surface 41 is parallel to the first groove section 121, and the second surface 42 is parallel to the second groove section 122; at least one second slide groove 421 is opened on the second surface 42, and the extension direction of the second slide groove 421 is parallel to the extension direction of the first groove section 121, and the second adapter 25 is provided with at least one sliding stabilizer 26 on the side facing the base 4, and the sliding stabilizer 26 can be slidably arranged in the second slide groove 421, and the shape of the sliding stabilizer 26 is adapted to the shape of the second slide groove 421.

[0074] Therefore, when the rack 22 drives the second transmission member 233 and the second adapter 25 to move along the second direction, the second adapter 25 moves stably in the second slide groove 421 through the sliding stabilizer 26, thereby assisting the rack 22 and the second transmission member 233 to move more stably along the second direction.

[0075] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the charging port opening and closing device also includes an actuator 5 , the gear 21 , the rack 22 and the actuator 5 are all located on the same side of the side, and the output end of the actuator 5 is connected to the gear 21 .

[0076] The actuator 5 can output rotational power in response to an external command. The output end of the actuator 5 is connected to the gear 21 and can drive the gear 21 to rotate in one direction or another according to the command.

[0077] The actuator 5 may be disposed on a side surface of the housing 1 , and the gear 21 and the rack 22 are disposed on the same side surface where the actuator 5 is disposed.

[0078] Therefore, only one actuator 5 is required to drive the cover plate 3 to open or close the charging port 11 , thereby reducing the driving cost.

[0079] In some embodiments of the present application, Figure 7 As shown, the second sliding groove 421 is disposed on a side of the second surface 42 close to the actuator 5 .

[0080] Since the gear 21, rack 22 and actuator 5 are located on the same side and these components are only provided on one side, when it is running, the forces on both sides are uneven, and the movement stability may be poor. Therefore, the sliding stabilizer 26 and the second slide groove 421 are arranged on the side closer to the actuator 5, which can assist the second adapter 25 to move and improve the stability of the entire device.

[0081] In some embodiments of the present application, Figure 6 As shown, an abutment member 13 is disposed inside the housing 1 , the abutment member 13 is fixedly connected to the housing 1 , and is arranged parallel to and spaced apart from the first slide slot 12 , and the surface of the abutment member 13 facing the first slide slot 12 abuts against the second transmission member 233 .

[0082] Therefore, when the second transmission member 233 moves, it can always abut against the abutment member 13 , and the abutment member 13 can always provide supporting force to the second transmission member 233 , thereby ensuring the movement stability of the second transmission member 233 .

[0083] In some embodiments of the present application, Figure 6 As shown, the second transmission member 233 includes a first part 2331 and a second part 2332, the first part 2331 and the second part 2332 intersect, the free end of the first part 2331 abuts against the abutment member 13, the second part 2332 is connected to the second adapter 25, and the end of the second part 2332 facing away from the first part 2331 is hinged to the first adapter 24.

[0084] The first part 2331 and the second part 2332 are connected to form an approximately L-shape. The end of the first part 2331 away from the second part 2332 is regarded as a free end, and the free end of the first part 2331 abuts against the abutment member 13. Since the free end of the first part 2331 abuts against the abutment member 13, the second transmission member 233 can move relatively smoothly along the second direction.

[0085] The present application also provides a vehicle, which includes the above-mentioned charging port opening and closing device.

[0086] In the vehicle provided in the embodiment of the present application, the cover plate 3 is driven to open or close the charging port 11 by the cooperation of the gear 21 and the rack 22, so that the cover plate 3 can move relatively smoothly and controllably, with a simple structure and low cost, which helps to achieve automatic control.
