[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0020] like Figures 1 to 15 As shown, a charging port cover assembly includes a housing 1, a cover 2, a first sealing ring 3, and a second sealing ring 4. The housing 1 is an open annular structure formed by continuous sidewalls, and its inner cavity 101 is a channel that runs through both ends. The two ends of the inner cavity 101 are respectively matched with the car charging port and the cover 2. The cover 2 is hinged to the sidewall of the housing 1. The first sealing ring 3 is disposed at the end where the housing 1 and the cover 2 mate, and is used to seal the contact surface between the housing 1 and the cover 2 when the cover 2 is closed; The second sealing ring 4 is located at one end of the housing 1 near the car charging port, and is used to seal the charging port during charging to prevent rainwater from entering the charging port.

[0021] The charging port cover assembly of this invention is applied to electric vehicle charging scenarios. Installed at the location of the vehicle's charging port, it protects the charging port from rainwater, dust, and other impurities entering during both non-charging and charging states, thus ensuring charging safety and equipment lifespan. The housing 1 of this invention is an open annular structure formed by continuous sidewalls, ensuring that the charging gun can penetrate the inner cavity 101 and engage with the vehicle's charging port during charging. The open annular structure can be either circular or square; this invention preferably uses a square annular structure with a smooth transition between adjacent sidewalls. The open annular structure of the housing 1 provides a suitable through-channel for the charging gun. During charging, the charging gun can smoothly pass through the inner cavity 101 and precisely engage with the vehicle's charging port to achieve the charging function.

[0022] When the cover 2 is in the closing process, since it is hinged with the side wall of the shell 1, when the cover 2 is rotated to the position closely attached to the shell 1, the closing action is completed. At this time, the first sealing ring 3 arranged at the matched end of the shell 1 and the cover 2 is pressed between the cover 2 and the shell 1, and by the elastic deformation of the sealing ring itself, the small gap between the contact surface of the cover 2 and the shell 1 is filled, a sealing barrier is formed, which prevents the rain and dust from the outside into the inner cavity 101 of the shell 1, thereby protecting the charging port from pollution.

[0023] When the cover 2 needs to be opened for charging, the cover 2 is rotated around the side wall of the shell 1 to be opened, so that the automobile charging port is exposed. Then the charging gun is inserted into the charging port, and the charging gun will penetrate the through hole in the middle of the second sealing ring 4 arranged at the end of the shell 1 close to the automobile charging port. When the charging gun is inserted into the charging port, the second sealing ring 4 is tightly attached to the outer periphery of the charging gun by virtue of its elasticity, and a sealed environment is formed between the charging gun and the charging port, which effectively prevents the rain and dust from the outside from entering the automobile interior through the charging port during the charging process, and ensures the safety and stability of the charging process.

[0024] The first sealing ring 3 and the second sealing ring 4 are arranged in the present application, which realizes the double sealing protection of the automobile charging port in different states. When the cover 2 is closed, the first sealing ring 3 prevents the rain and dust from entering the inner cavity 101 of the shell 1, and avoids the damage of impurities accumulation to the charging port; when the cover 2 is opened for charging, the second sealing ring 4 prevents the rain and dust from entering the charging port, which ensures that the charging process is not affected by the external environment, improves the service life and charging safety of the automobile charging port, and also improves the overall use reliability and user experience of the automobile.

[0025] The first sealing ring 3 and the second sealing ring 4 in the present application can be connected by a groove connection or a mechanical pressing connection, and the specific connection mode can be selected according to actual needs. In order to facilitate installation and maintenance, the present application adopts a detachable connection mode.

[0026] As Figures 1 to 7 , Figure 11As shown, in a preferred embodiment of the present invention, the first sealing ring 3 is fixedly disposed on the outer periphery of the edge of the housing 1, and the first sealing ring 3 is also provided with an assembly part 303. A fixing pin 304 is fixed on the assembly part 303, and a fixing hole 105 corresponding to the fixing pin 304 is opened on the housing 1. The fixing pin 304 and the fixing hole 105 are interference-fitted. There are two or more assembly parts 303, which are evenly distributed on the first sealing ring 3, and the number of fixing pins 304 and fixing holes 105 matches the number of assembly parts 303. Using this embodiment, when installing the first sealing ring 3, it is only necessary to accurately insert the fixing pin 304 into the corresponding fixing hole 105. The connection can be firmly established by the friction generated by the interference fit. The operation is simple and convenient, without the need for complicated tools or professional skills, and the installation process can be completed quickly. When the first sealing ring 3 needs to be replaced due to wear or aging, its detachable interference fit connection means that only appropriate external force needs to be applied to overcome the friction generated by the interference fit to pull the fixing pin 304 out of the fixing hole 105, thereby removing the first sealing ring 3 for replacement. When replacing the first sealing ring 3, simply reinsert the fixing pin 304 according to the installation steps. The maintenance process is simple and quick, reducing maintenance time and costs. In this invention, the fixing pin 304 can also be replaced with other connecting parts, such as connecting studs. When using connecting studs, after the stud is embedded in the fixing hole 105, it needs to be tightened with a nut on the housing 1.

[0027] like Figures 1 to 4 , Figure 11 As shown, in this embodiment, the outer periphery of the second sealing ring 4 is fixedly connected to the outer periphery of the cavity. The edge of the second sealing ring 4 is a circumferential stepped surface 402. When assembling the second sealing ring 4, the circumferential stepped surface 402 can be directly bonded and fixed to the outer periphery of the cavity. The bonding and fixing method of the present invention is simple to operate, has low requirements for the installation environment and technology, and can quickly achieve the installation and positioning of the second sealing ring 4, improving installation efficiency. The second sealing ring 4 is fixed to the outer periphery of the cavity by bonding. When maintenance and replacement are required, the bonding can be removed by a suitable method, such as using a solvent to dissolve the adhesive, and then the old second sealing ring 4 can be removed, and the new second sealing ring 4 can be installed to the outer periphery of the cavity by bonding.

[0028] like Figures 1 to 7 As shown, in this invention, the top sidewall 102 of the inner cavity 101 is higher than the bottom sidewall 103 to prevent water from entering the charging port during charging; and the bottom sidewall 103 of the inner cavity 101 is inclined downward to drain the water flow in the inner cavity 101.

[0029] The top side wall 102 of the inner cavity 101 in the application is higher than the bottom side wall 103, so that the height difference between the top side wall 102 and the bottom side wall 103 forms a natural barrier. During the charging process, if rainwater or other water flows fall on the charging port cover assembly, due to the higher top side wall 102, the water flow is difficult to directly enter the inner cavity 101, thereby effectively preventing the water flow from entering the charging port, and ensuring the safety of the charging port in a humid environment.

[0030] The bottom side wall 103 of the inner cavity 101 in the application is downwardly inclined, which plays a key role when a small amount of water flow accidentally enters the inner cavity 101 or water accumulates in the inner cavity 101 due to other reasons. The inclined bottom side wall 103 utilizes the action of gravity to make the water flow naturally flow downward along the inclined surface 412, and finally be guided out of the inner cavity 101, avoiding the accumulation of water flow in the inner cavity 101, and further reducing the risk of damage to the charging port caused by the water flow.

[0031] The above structure of the application physically blocks the entry of water flow, greatly reduces the risk of short circuit, damage to charging equipment and other safety hazards caused by the invasion of rainwater or other water flow into the charging port during the charging process, and improves the reliability and stability of the automobile charging system in a humid environment. At the same time, the downward inclination of the bottom side wall 103 of the inner cavity 101 can timely guide the water flow entering the inner cavity 101 out, avoiding the long-term accumulation of water flow in the inner cavity 101, preventing corrosion, rust and other problems caused by water accumulation, and prolonging the service life of the charging port cover assembly and related charging equipment.

[0032] As shown in Figures 1 to 5 , Figure 12 In the application, the second sealing ring 4 is provided with a flow guide convex strip 401 on one side of the inner cavity 101 for guiding the downward flow of water flow, the upper end of which is close to the top side wall 102 of the inner cavity 101, the lower end of which is close to the bottom side wall 103 of the inner cavity 101, and the flow guide convex strip 401 is inclined from the outside of the inner cavity 101 to the inside of the inner cavity 101 from top to bottom.

[0033] In actual work, when rainwater or other water flows into the inner cavity 101 and contacts the second sealing ring 4, due to the special structure design that the upper end of the flow guide protruding strip 401 is close to the top side wall 102 of the inner cavity 101, the lower end is close to the bottom side wall 103 of the inner cavity 101, and the flow guide protruding strip 401 is inclined from the outside of the inner cavity 101 to the inside of the inner cavity 101 from top to bottom, the water flow will flow along the direction of the flow guide protruding strip 401. Specifically, the water flow first falls on the protruding surface 411 of the flow guide protruding strip 401, and because the protruding surface 411 is smoothly connected with the two inclined surfaces 412, the water flow will naturally and smoothly flow down along the inclined surface 412, and finally flow out from the position close to the bottom side wall 103 of the inner cavity 101, instead of randomly accumulating on the surface of the second sealing ring 4 or seeping into the inside of the inner cavity 101, thereby achieving the effect of guiding the water flow out of the inner cavity 101.

[0034] The design of the flow guide protruding strip 401 can effectively guide the direction of the water flow, avoid the water flow from accumulating at the second sealing ring 4 and then seeping into the inner cavity 101 through the gap, and then entering the charging port of the automobile, thereby greatly improving the waterproof capability of the charging port cover assembly, reducing the risk of short circuit and damage of the charging equipment caused by the water flow, and ensuring the safety of the charging process and the reliability of the charging equipment. Moreover, the structure that the flow guide protruding strip 401 is inclined from the outside of the inner cavity 101 to the inside of the inner cavity 101 from top to bottom enables the water flow to be quickly and smoothly discharged from the inner cavity 101, and compared with the case without the flow guide structure, the drainage is more efficient, the time for the water flow to stay in the inner cavity 101 is reduced, and the possibility of the water flow causing adverse effects on the charging port and related components is further reduced.

[0035] As shown in Figures 1 to 5 , Figure 12 , the second sealing ring 4 is integrally formed as a whole, and the part of the inner ring of the second sealing ring 4 in contact with the charging port is also a protruding strip structure, specifically including a first rising inclined surface 404, a second rising inclined surface 405 and a protruding top 406, the first rising inclined surface 404 is located at the innermost side of the sealing ring and is used for tightly abutting the charging gun. The first rising inclined surface 404, the second rising inclined surface 405 and the protruding top 406 of the present application cooperate to achieve the effect of sealing the outer periphery of the charging gun and guiding the water flow, which is the same as the flow guide protruding strip 401.

[0036] As shown in Figures 1 to 4 , Figure 12 , in the present application, first locking mechanism 5 and second locking mechanism 6 are further arranged on the shell 1 and the cover 2 respectively, and the unlocking or locking of the cover 2 is realized by cooperation of the first locking mechanism 5 and the second locking mechanism 6. The first locking mechanism 5 includes a driving motor and a clamping strip 501; the second locking mechanism 6 includes a clamping cavity 601 and a clamping port 602, the shape of the clamping port 602 is matched with the shape of the clamping strip 501; In the locking process, the clamping strip 501 is clamped in the clamping cavity 601 after passing through the clamping port 602 to achieve locking; in the unlocking process, the clamping strip 501 is rotated to a position matched with the clamping port 602, and the cover body 2 is opened to achieve unlocking.

[0037] The cover body 2 comprises an outer cover plate 201 and an inner cover plate 202, the inner cover plate 202 is fixedly connected in the inner cover plate 202, and the inner cover plate 202 is matched in shape with the inner cavity 101 of the shell 1. When the cover body 2 is closed, the inner cover plate 202 is embedded in the inner cavity 101, and the outer cover plate 201 can be tightly attached to the outer periphery. The second locking mechanism 6 is arranged on the inner cover plate 202.

[0038] The first locking mechanism 5 of the application further comprises a lock shell 502 for assembling a driving motor, and the driving motor is arranged in the lock shell 502. The first locking mechanism 5 further comprises a first cylinder 503 and a second cylinder 504 arranged concentrically from inside to outside, the first cylinder 503 is rotatably connected to the second cylinder 504, the second cylinder 504 is movably arranged on the shell 1, and the bottom of the second cylinder 504 is provided with an elastic member (not shown). The clamping strip 501 is fixedly arranged on the end face of one end of the first cylinder 503, and the center of the clamping strip 501 is further provided with a contact piece 505. The clamping cavity of the second locking mechanism 6 is further provided with a compression contact piece 603 matched with the contact piece 505.

[0039] In the locking process after the cover body 2 is charged, the clamping strip 501 in the first locking mechanism 5 moves with the cover body 2, passes through the clamping port 602 on the second locking mechanism 6, and enters the clamping cavity 601. At this time, since the clamping strip 501 is positionally corresponding to the clamping port 602, only preliminary positioning is completed, and locking is not achieved. When the clamping strip 501 enters the clamping cavity 601, the compression contact piece 603 in the clamping cavity will abut against the contact piece 505 in the center of the clamping strip 501. The compression contact piece 603 will generate a pushing force on the contact piece 505, and push the first cylinder 503 and the second cylinder 504 to move along the direction of the lock shell 502. When the second cylinder 504 contacts the driving motor press switch in the lock shell 502, the driving motor is triggered to start. After the driving motor starts, the first cylinder 503 connected thereto is rotated. Since the clamping strip 501 is fixedly arranged on the end face of one end of the first cylinder 503, the rotation of the first cylinder 503 will drive the clamping strip 501 to rotate by 90 degrees, so that the clamping strip 501 is clamped in the clamping cavity 601, thereby completing the locking of the cover body 2 and the shell 1.

[0040] When the cover 2 needs to be opened, the vehicle computer sends a command to control the driving motor to rotate. The driving motor drives the clamping strip 501 to rotate, so that the clamping strip 501 is rotated to a position matched with the position of the clamping port 602. Because the second column body 504 is provided with an elastic component at the bottom, after the clamping strip 501 is matched with the position of the clamping port 602, the elastic component drives the second column body 504 to move upward. The upward movement of the second column body 504 further pushes away the cover 2, so that the cover 2 is unlocked. In Figure 5 A1, A2, A3 and A4 are respectively a closed state, a preliminary opening state of the cover 2, an intermediate opening state and a fully open state.

[0041] The present application realizes the rotation of the clamping strip 501 through the driving motor, and further completes the locking and unlocking of the cover 2. Compared with the traditional manual locking mode, the operation process is greatly simplified, and the user only needs to control the driving motor through the vehicle computer to easily realize the opening and closing of the cover 2, thereby improving the convenience of use. At the same time, the cover 2 can be opened without manual pressing, and only a small force is needed to cooperate the first locking mechanism 5 and the second locking mechanism 6 to realize automatic locking when closing, so that the user does not need to press hard to lock, which can prevent the problem of inconsistent gap or misalignment between the cover 2 and the surrounding metal parts caused by deformation of the cover 2 in the pressing process, thereby ensuring the coordination and overall aesthetics of the vehicle appearance.

[0059] During the opening process of the cover plate, the hinge 9 rotates with the cover plate, because the first clamping piece 1112 is embedded in the first clamping hole 907 of the connecting part 901 of the hinge 9, the hinge 9 drives the first clamping piece 1112 to displace, pulls the limiting cable 11, and makes the limiting cable 11 straight. At this time, the second clamping piece 1122 drives the limiting arm 1002 to rotate around the hinge shaft 1010 under the action of the tension of the limiting cable 11, so that the end of the limiting arm 1002 is clamped on the sliding path of the sliding door, preventing the sliding door from impacting the cover body 2.

[0060] In one specific application of the present application, the charging port cover assembly is applied to an existing automobile, and the automobile is a common automobile with a sliding door and a charging function in the prior art.

[0061] ​The following describes the working process of the charging port cover assembly in the invention in detail. I. Opening the cover body 2 The user issues an instruction to open the cover body 2 through the vehicle-mounted computer or a manual button. After receiving the instruction, the vehicle-mounted computer controls the drive motor on the first locking mechanism 5 to start. The drive motor drives the first column body 503 connected thereto to rotate, thereby causing the clamping block fixed to the end face of the first column body 503 to rotate. The clamping block rotates to a position matched with the position of the clamping interface 602 under the drive of the drive motor, at which time the clamping block no longer hinders the opening of the cover body 2. Since the second column body 504 is provided with an elastic component at the bottom, after the clamping block is matched with the position of the clamping interface 602, the elastic component pushes the second column body 504 to move upward, further pushing the cover body 2 to achieve the initial unlocking of the cover body 2. The cover body 2 starts to rotate and open around the hinge 9 under the action of the elastic component, and the user can manually or continue to open the cover body 2 to the required angle through the electric mode. During the opening of the cover body 2, the hinge 9 rotates synchronously with the cover body 2 and stretches the torsion spring 13 to provide a buffer force for the subsequent closing of the cover body 2. After the cover body 2 is opened, the switch contact point 906 on the hinge 9 moves out of the position of the switch swing arm 801, the state of the switch assembly 8 changes, the circuit of the charging indicator light 7 is turned on, and the indicator light is turned on to prompt the user that the charging port is available.

[0062] II. Closing the cover body 2 After the user finishes charging, the user issues an instruction to close the cover body 2 through the vehicle-mounted computer or a manual button. If the closing is in the electric mode, the vehicle-mounted computer controls the drive motor to rotate reversely to drive the clamping block to return to the initial position for locking. Then the user manually pushes the cover body 2 in the closing direction, and the cover body 2 rotates and closes around the hinge 9. The hinge 9 rotates synchronously with the cover body 2 and compresses the torsion spring 13 to provide a buffer for the closing of the cover body 2 and prevent the cover body 2 from being closed too fast to cause impact. With the closing of the cover body 2, the strip-shaped clamping block in the first locking mechanism 5 moves with the cover body 2, passes through the clamping interface 602 on the second locking mechanism 6, and enters the clamping cavity 601. After the clamping block enters the clamping cavity 601, the pressing component 603 in the clamping cavity pushes the contact component 505 at the center of the clamping block to drive the first column body 503 and the second column body 504 to move along the direction of the lock shell 502 until the second column body 504 contacts the drive motor pressing switch in the lock shell 502 to trigger the drive motor to start. The drive motor drives the first column body 503 to rotate, thereby causing the clamping block to rotate by 90 degrees and be clamped in the clamping cavity 601 to complete the locking of the cover body 2 and the shell 1. After the cover body 2 is completely closed, the switch contact point 906 on the hinge 9 presses the switch swing arm 801 to cause the switch assembly 8 to be in the closed state and disconnect the circuit of the charging indicator light 7.

[0063] III. Working process of the vehicle door limiting assembly 10 When the cover 2 is opened, the rotation of the hinge 9 drives the movement of the limiting cable 11, and the limiting arm 1002 in the door limiting assembly 10 connected to the other end of the limiting cable 11 is pulled and rotated. After the rotation of the limiting arm 1002, it is clamped on the sliding path of the sliding door, preventing the sliding door from accidentally moving and hitting the cover 2 during charging.

[0064] IV. Reset process of the door limiting assembly 10 During the closing process of the cover 2, the rotation direction of the hinge 9 is changed, the limiting cable 11 is relaxed, and the limiting arm 1002 in the door limiting assembly 10 returns to the initial position under the action of gravity, no longer hindering the normal sliding of the sliding door.

[0065] The above specific embodiments further explain the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above description is only a specific implementation method of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit of the present application should be included in the protection scope of the present application.
