Abstract
Description
Technical Field
[0001] This invention belongs to the field of new energy vehicle charging technology, and particularly relates to a new energy vehicle charging port cover and its control method, and a new energy vehicle. Background Technology
[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.
[0003] Currently, new energy vehicles are gradually becoming mainstream products in the automotive market; the per capita ownership of new energy vehicles is also rapidly increasing. To ensure the charging safety and reliability of the charging structure of new energy vehicles, the charging interface of new energy vehicles must be equipped with a sealed charging port cover for protection.
[0004] There are two main types of opening methods for the charging port cover of existing electric vehicles: one is the outward-flipping type, such as patent number ZL2023213738738, and the other is the outward-rotating type, such as patent number ZL2014102206511. Both types of charging port covers have the problem of protruding from the curved surface of the vehicle body when opened. In particular, the outward-flipping type charging port cover is almost perpendicular to the curved surface of the vehicle body after it rotates relative to the curved surface of the vehicle body, and protrudes from the curved surface of the vehicle body very high. During the charging period, the charging port cover is in a protruding state for a long time, which is particularly easy to catch the clothes of pedestrians or scratch their bodies, affecting the safety of pedestrians crossing between two vehicles. Summary of the Invention
[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a charging port cover for new energy vehicles and its control method, as well as a new energy vehicle.
[0006] To achieve the above objectives, a first aspect of the present invention provides a charging port cover for a new energy vehicle, comprising:
[0007] The mobile frame includes a wheel frame and a pole;
[0008] The cover seat is connected to the wheel frame rod via a connecting rod. The upper end of the connecting rod is connected to the bottom surface of the cover seat via a hinge structure one, and the lower end of the connecting rod is connected to the wheel frame rod via a hinge structure two.
[0009] The hinged structure two is rotatably connected to roller one;
[0010] The track has a groove inside, and a roller is rotatably connected to the groove.
[0011] End plates and limit plates are respectively installed at both ends of the track;
[0012] The telescopic rod has one end hinged to the end plate and the other end fixedly connected to the movable frame.
[0013] The angle between the connecting rod and the track is 10°-85°.
[0014] This invention utilizes a telescopic rod to move a movable frame along a track. When the charging port cover changes from an open to a closed state, the inner tube of the telescopic rod extends, pushing the movable frame towards a limiting plate. When the cover contacts the limiting plate, the movable frame continues to move towards the limiting plate. Under the force of the movable frame and the limiting plate, the cover lifts upward until it engages with the vehicle body panel. When the charging port cover changes back to an open state, the inner tube of the telescopic rod retracts, moving the movable frame towards the end plate. At this time, the cover falls, approaching roller one, achieving a sinking and retraction of the cover and movable frame, moving towards the end plate. This device ensures that the charging port cover, when open, is hidden under the vehicle body panel and does not protrude from the vehicle body, preventing it from affecting the safety of pedestrians.
[0015] In some embodiments, the movable frame includes a wheel frame rod, which is arranged parallel to the telescopic rod and is fixedly connected to the telescopic rod by a support rod; a track is provided on the outside of the wheel frame rod, and a roller is disposed in the groove of the track.
[0016] The use of wheeled frames and telescopic poles reduces the size of the mobile frame, making it easier to install in small spaces.
[0017] In some embodiments, the movable frame includes two parallel and oppositely arranged wheel frame rods, which are fixedly connected by a support rod; a track is provided on each side of the wheel frame rod, and a roller is disposed in the groove of the track.
[0018] By setting up a pair of parallel and opposite wheel frame rods, the stress on the wheel frame, cover seat, etc. is made more stable, which improves the service life of the equipment and the sealing and waterproofing effect.
[0019] In some implementations, the telescopic rod is hinged to the end plate, and the telescopic rod is fixedly connected to the support rod.
[0020] In some implementations, an outer cover is fixedly connected to the top surface of the cover seat, and the outer cover is matched with the body panel.
[0021] In some implementations, the cover is made of both hard and soft plastic, with the middle section being hard plastic and the outer edge being soft plastic. The soft plastic is bonded to the vehicle body panels to achieve a waterproof seal.
[0022] In some implementations, the charging port cover is installed at an angle, tilted 30-50° relative to the ground on the body panel.
[0023] In some embodiments, a magnetic attraction device is also included, comprising two magnetic elements respectively disposed on the bottom surface of the cover and between the two tracks. When the charging port cover is switched to the open state, the magnetic attraction force of the magnetic attraction device pulls the cover towards the track, causing the cover and the moving frame to fold.
[0024] In some embodiments, the telescopic rod is an electrically operated telescopic rod, and one of the magnetic components of the magnetic attraction device is an electromagnet, whose magnetism is generated or eliminated by controlling the circuit switching.
[0025] In some embodiments, a controller is also included, and a proximity switch is provided on the inner side above the limit plate. The electromagnet, the electric telescopic rod, and the proximity switch are all connected to the controller.
[0026] The second aspect of the present invention provides a control method for opening and closing a charging port cover of a new energy vehicle. When the charging port needs to be closed, the motor of the electric telescopic rod rotates forward and sends a signal to the controller, which then controls the electromagnet to de-energize. When the charging port is opened, the electric telescopic rod rotates in reverse and sends a signal to the controller, which then controls the electromagnet to be energized, attracting another magnetic component and causing the cover to sink. When the cover sinks to its lowest position, a proximity switch sends a signal to the controller, which then controls the electromagnet to de-energize.
[0027] A third aspect of the present invention also provides a new energy vehicle, including the aforementioned charging port cover.
[0028] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:
[0029] 1. The sliding charging port cover of the new energy vehicle of the present invention, when the charging port cover is opened for charging, retracts through the telescopic rod to hide the charging port cover under the body panel, so that it does not protrude outside the body and prevents it from affecting the safety of pedestrians passing by; when the charging port cover is closed after charging is completed, the telescopic rod extends and the connecting rod lifts the cover seat and the charging port cover together, so that the cover seat is tightly attached to the body panel and achieves a waterproof and sealing effect.
[0030] 2. The magnetic suction device of the present invention is designed to fit the curved surface of the vehicle body panel. Therefore, the device is often set at an angle to the ground. Through the attraction of the two magnetic components, when the telescopic rod is retracted, the magnetic attraction of the magnetic components of the magnetic suction device attracts the cover to move towards the track, thereby realizing the folding of the cover and the moving frame. The magnetic suction sinks and slides inward, thus smoothly opening the charging port cover. Attached Figure Description

[0036] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0037] As described in the background section, existing technologies have a problem where the charging port cover protrudes from the curved surface of the vehicle body, affecting the safety of pedestrians. In order to solve the above-mentioned technical problem, this invention proposes a charging port cover for new energy vehicles and a new energy vehicle.
[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0039] One or more embodiments of the present invention describe a charging port cover for new energy vehicles, such as... Figure 1 As shown, the charging port cover includes an end plate 14, a track 1, and a limiting plate 11. Two tracks 1 are arranged in parallel, and each track 1 has a groove 12 on its opposite side. The grooves 12 are positioned opposite each other and accommodate rollers 32. The end plate 14 is fixedly mounted on one end of each track 1, and the limiting plate 11 is fixedly mounted on the other end. The rollers 32 move back and forth within the track 1, causing the charging port cover to open or close.
[0040] The movable frame 3 includes two parallel and oppositely arranged wheel frame rods 33. Both ends of the wheel frame rods 33 are connected to the connecting rod 4. The ends of the wheel frame rods 33 are connected to the lower end of the connecting rod 4 through a second hinge structure 10. The upper end of the connecting rod 4 is connected to the cover 5 through a first hinge structure 9. A first roller 32 is rotatably connected to the outer side of the second hinge structure 10. Optionally, the first hinge structure 9 is also rotatably connected to a second roller.
[0041] Roller 32 rolls back and forth in the groove 12 of track 1. The bottom surface of cover 5 is provided with four hinge seats 51, which form a hinge structure 9 with the upper end of the four connecting rods 4 respectively.
[0042] A support rod 31 is fixedly connected between the two opposing wheel frame rods 33. The support rod 31 is perpendicular to the wheel frame rods 33. One end of the telescopic rod 2 is fixedly connected to the support rod 31, and the other end is hinged to the end plate 14. At this time, the telescopic rod 2 and the wheel frame rod 33 are parallel to each other so that the cover seat 5 is evenly stressed and achieves a good seal.
[0043] The cover 5 is made of hard plastic and soft plastic. The middle of the cover 5 is made of hard plastic and the outer edge is made of soft plastic. The shape of the cover 5 matches the shape of the charging port. The soft plastic fits into the surrounding body panels to achieve a waterproof and sealing effect. An outer cover 6 is fixedly connected to the cover 5. The shape of the outer cover 6 conforms to the curved surface of the body panels. Optionally, the cover 5 and the outer cover 6 are integrally formed.
[0044] The four connecting rods 4 are of equal length and parallel to each other. The limiting plate 11 is set perpendicular to the track 1. The angle between the connecting rods 4 and the track 1 is 10°-85° to prevent the cover 5 from going beyond the dead point of the mechanism. The height of the limiting plate 11 is set according to the length of the connecting rods and the preset lifting distance of the cover 5. When the cover 5 on the moving frame 3 abuts against the limiting plate 11, the electric telescopic rod 2 continues to push the moving frame 3 toward the limiting plate 11, and the cover 5 is lifted upward along the limiting plate 11 until the connecting rods 4 reach the preset height.
[0045] A charging port inner cover 13 is provided on the side away from the cover 5 between the two tracks 1. The charging port inner cover 13 is arranged parallel to the cover 5. The magnetic attraction device includes two magnetic components, namely magnet 7 and magnet 8, which are respectively set on the bottom surface of the cover 5 and the inner cover between the two tracks 1. When the charging port cover is switched to the open state, the magnetic attraction force of the magnetic attraction device pulls the cover 5 to move towards the track 1, so that the cover 5 and the moving frame 3 sink down and are stored.
[0046] The magnetic attraction device can also be set as an electromagnet, and the telescopic rod 2 can be set as an electric telescopic rod. The generation and disappearance of the magnetism of the electromagnet and the extension and retraction of the electric telescopic rod work together to realize the opening and closing of the charging port cover.
[0047] Specifically, one electromagnetic component 7 of the magnetic attraction device is an electromagnet, and the other electromagnetic component 8 is an iron sheet. A proximity switch is set on the inner side above the limit plate 11. The electromagnet, the electric telescopic rod, and the proximity switch are all connected to the controller. When the charging port needs to be closed, the motor of the electric telescopic rod rotates forward and sends a signal to the controller. The controller controls the electromagnet to de-energize and demagnetize.
[0048] The control method for opening and closing the charging port cover of new energy vehicles is as follows: When the charging port is opened, the electric telescopic rod reverses and sends a signal to the controller, which then controls the electromagnet to be energized; the electromagnet attracts the iron sheet, causing the cover 5 to sink; when the cover 5 sinks to the lowest position, the proximity switch sends a signal to the controller, which then controls the electromagnet to be de-energized and demagnetized.
[0049] The charging port cover is installed at the charging port location of the new energy vehicle and is located inside the body panel. When the moving frame 3 and the cover seat 5 move towards the limiting plate 11, the cover seat 5 is lifted so that the outer cover 6 fits against the body panel, achieving a seal between the outer cover 6 and the surrounding body panel, thus closing the charging port cover. When the moving frame 3 and the cover seat 5 move towards the end plate 14, the magnetic component attracts the cover seat 5 and the outer cover 6 to move inward and hide them under the body panel, thus achieving a hidden opening.
[0050] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
