Description

Technical Field

[0001] The present invention relates to the technical field of charging covers, and in particular to an automatic opening structure for a charging port cover of a new energy vehicle. Background Art

[0002] New energy vehicles are mostly powered by electricity and require additional power during use. In order to make it more convenient for users to use, many types of automatic opening structures have appeared on the covers at the charging port.

[0003] The existing Chinese patent with publication number CN112590945A discloses a charging port opening device, including a charging port box and a charging port cover that can be covered on the charging port box. The charging port opening device also includes a connecting rod provided on the side of the charging port box away from the charging port cover and a power device connected to the connecting rod in a transmission manner. The charging port box is provided with a rotating movable groove, and the connecting rod extends from the rotating movable groove to the charging port box and is pivotally connected to the charging port cover. The power device is used to drive the connecting rod to move between the starting end and the ending end of the rotating movable groove, driving the charging port cover to be covered on the charging port box or to expose the charging port box. The power device is connected to a control device, which is used to automatically control the connecting rod to move between the starting end and the ending end of the rotating movable groove according to the control signal of the control device. The connecting rod is connected to the power device through a gear pair. The present invention also discloses an electric vehicle including the above-mentioned charging port opening device.

[0004] Existing new energy vehicles are all equipped with automatic opening structures of charging port covers with different opening methods. In actual experience, it is found that since the charging port includes a DC charging port and an AC charging port, the charging gun will only be inserted into one charging port during charging, and the other charging port will be exposed. When charging outdoors, if it encounters rainy or snowy weather, rain and snow will enter the vicinity of the charging port. Although the existing charging port will not be directly short-circuited due to water ingress, rainwater will cause oxidation corrosion of some circuits, resulting in a decrease in charging rate or spontaneous combustion. The existing charging port cover will automatically close after use, which is inconvenient for users to actively clean the water near the charging port. Summary of the Invention

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example:

[0037] Reference Figures 1 to 10, the automatic opening structure of the charging port cover of a new energy vehicle includes a body 1 and an arc connector 2 connected by a drive component. The outer end of the arc connector 2 is fixedly connected to a cover plate 3. When charging is needed, it is controlled by the on-board computer program. After manual triggering, the drive component drives the arc connector 2 to be ejected outward along its shape, and then the charging port in the body 1 is exposed. Since the drive component and the on-board computer program belong to relatively mature existing technologies, they are not described in detail here. At the same time, they are not shown in the drawings of the specification. A water baffle 4 is slidably installed in the cover plate 3, and a connecting frame 5 is installed between the water baffle 4 and the body 1 for common rotation;

[0038] Among them, the water baffle 4 is a cavity structure, and a lifting component 6 is fixedly installed inside the water baffle 4. A pressing component 7 in contact with the lifting component 6 is slidably installed inside the water baffle 4, and the pressing component 7 includes a pressing plate 701 that slides unidirectionally in an inclined state.

[0039] During the process of the arc connector 2 being pushed out, the cover 3 is in a state of rotating and moving upward. Due to the position limitation of the connecting frame 5, the water baffle 4 sliding in the cover 3 will slide upward relative to the cover 3. After the cover 3 rotates to the specified position, the water baffle 4 will also be extended to the maximum. At this time, the water baffle 4 will be pressed against the vehicle body 1, covering the top of the charging port. In this way, it can play a certain blocking role when it rains, so that the charging gun can reduce the erosion of rainwater when in use, and increase the stability of the device when used outdoors.

[0040] At the same time, after the water baffle 4 is extended, when it rains, rainwater will enter the water baffle 4. Through the action of the lifting component 6, the top pressure plate 701 in the water baffle 4 will slide out. After sliding out, the top pressure plate 701 will support the vehicle body 1, thereby reducing the gap between the vehicle body 1 and the water baffle 4, so that rainwater cannot flow from the gap to the vicinity of the charging port, further reducing the erosion of rainwater and improving the rain protection ability.

[0041] Specifically, refer to Figure 4 and Figure 9 The top pressure plate 701 is slidably inserted in the water baffle 4, and the bottom end of the top pressure plate 701 contacts the lifting component 6. A diamond groove 702 is provided on one side of the top pressure plate 701, and a limiting plate 703 is rotatably connected in the diamond groove 702. A plurality of triangular grooves 705 are evenly provided on one side of the water baffle 4 corresponding to the diamond groove 702, and an air cavity 704 is provided at the top of the top pressure plate 701.

[0042] Specifically, refer to Figure 5The lifting assembly 6 includes a rotating groove 602 opened on the water baffle 4, and a rotating lever 603 is rotatably installed on the side wall of the rotating groove 602 through a fulcrum. The two ends of the rotating lever 603 are respectively rotatably installed with a sliding plate 601 and a push rod 604. The sliding plate 601 is slidably installed on one side inner wall of the water baffle 4, and a spring 605 is fixedly installed between the sliding plate 601 and the water baffle 4.

[0043] When rainwater enters the water baffle 4, the water baffle 4 is in an inclined state. The rainwater accumulated in the water baffle 4 will press the sliding plate 601 to slide downward. At the same time, the spring 605 is compressed, and the push rod 604 moves upward to push the top pressure plate 701 outward. The top pressure plate 701 is used to increase the sealing between the water baffle 4 and the vehicle body 1. In the inclined state of the water baffle 4, the limit plate 703 in the diamond groove 702 will naturally rotate downward by a certain angle, and the inclined side wall of the diamond groove 702 is used to form a blocking part. When the limiting plate 703 rotates into the triangular slot 705, the bottom of the limiting plate 703 will also press against the side wall of the triangular slot 705, so that the limiting plate 703 rotates into the triangular slot 705 to form a limiting assembly, and the top pressure plate 701 cannot be retracted after being extended, which can prevent the top pressure plate 701 from being affected by external shaking or collision, or the loss of water causing the top rod 604 to retract, and the top pressure plate 701 returns, so that it can always remain in the state of being pushed out, thereby maintaining the effect of blocking rainwater.

[0044] Specifically, refer to Figure 4 、 Figure 6 and Figure 8 A siphon drainage component 8 is installed horizontally through the water baffle 4, and a drainage pipe 9 is installed through one side plate of the water baffle 4.

[0045] Specifically, refer to Figure 6 and Figure 8 The siphon drainage assembly 8 includes a drainage elbow 801 installed through the water baffle 4, one end of the drainage elbow 801 is perpendicular to the side plate of the water baffle 4, the pipe body of the drainage elbow 801 is folded 180° and vertically penetrates one side of the water baffle 4, a fixing frame 802 is fixedly installed at the end of the drainage elbow 801, a rotating shaft 803 is rotatably installed in the fixing frame 802, and a turbofan 804 and a mesh plate 805 are fixedly installed at both ends of the rotating shaft 803, and the turbofan 804 is located in the drainage elbow 801.

[0046] When the water baffle 4 remains in an inclined state, rainwater will enter the water baffle 4, which can reduce the leakage caused by rainwater passing through the connection between the water baffle 4 and the cover plate 3, and can also reduce the rainwater entering the vicinity of the charging port. After the rainwater enters the water baffle 4, after the rainwater exceeds the bending point of the drainage elbow 801, a siphon effect is formed in the drainage elbow 801, and the rainwater will be concentrated and discharged from the water baffle 4. At the same time, the outflowing water has a certain pressure and a certain flow rate. At the same time, the water flow will drive the turbofan 804 to rotate, and the turbofan 804 will drive the mesh plate 805 to rotate together. When the water flows out through the drainage elbow 801, debris will be blocked by the mesh plate 805, and during the rotation of the mesh plate 805, the debris will continue to leave the mesh plate 805 under the action of centrifugal force. The position of the end of the drainage elbow 801 can be kept as unobstructed as possible, so that the rainwater can be discharged smoothly from the water baffle 4, and too much rainwater will not accumulate in the water baffle 4.

[0047] Specifically, refer to Figure 4 and Figure 7 The siphon drainage component 8 is located above the sliding plate 601, and the drain pipe 9 is located below the sliding plate 601. A blocking component 10 is slidably inserted on one side of the sliding plate 601. The blocking component 10 is located on one side of the drain pipe 9. The blocking component 10 includes two blocking blocks 1004 that can block the drain pipe 9. The two blocking blocks 1004 block the drain pipe 9 when the water retaining plate 4 is in the vertical state and the maximum tilt state, respectively.

[0048] Specifically, refer to Figure 7 The blocking assembly 10 includes a limiting plate 1001 and a connecting rod 1002 slidably inserted on the sliding plate 601. The limiting plate 1001 is fixedly installed on the top of the connecting rod 1002. Two fixed plates 1003 are fixedly installed on the connecting rod 1002. The blocking block 1004 is fixedly installed on one side of the fixed plate 1003.

[0049] Specifically, refer to Figure 7 A second magnet 1006 is fixedly mounted on one side of the drain pipe 9 , and a first magnet 1005 that can be attracted to the second magnet 1006 is fixedly mounted on one side of the two fixed plates 1003 .

[0050] When the cover 3 is in the vertical state, the cover 3 is located in the vehicle body 1, and the spring 605 is pressed by the sliding plate 601. At this time, the uppermost fixed plate 1003 and the blocking block 1004 will block the drain pipe 9. In the process of opening the cover 3, the sliding plate 601 is tilted. At this time, the force on the spring 605 will become smaller, and the sliding plate 601 will be pushed outward. The fixed plate 1003 below will slowly move upward, and when the sliding plate 601 reaches the most tilted state, the fixed plate 1003 below and the blocking block 1004 will block the drain pipe 9, and when the sliding plate 601 is pressed by rainwater, the suction force between the first magnet 1005 and the second magnet 1006 can support the gravity of the tilt of the fixed plate 1003, so that when the cover plate 3 is in the vertical position and the maximum tilt position, the drain pipe 9 is blocked. During the rotation of the cover plate 3, the water in the water baffle 4 can be discharged outward through the drain pipe 9, so that the water in the water baffle 4 cannot enter the vehicle body 1 as the cover plate 3 rotates.

[0051] Working principle: During the process of the arc connector 2 being pushed out, the cover plate 3 is in a state of rotating and moving upward. Due to the position limitation of the connecting frame 5, the water baffle 4 sliding in the cover plate 3 will slide upward relative to the cover plate 3. After the cover plate 3 rotates to the specified position, the water baffle 4 will also be extended to the maximum. At this time, the water baffle 4 will be pressed against the vehicle body 1, covering the top of the charging port. In this way, it can play a certain blocking role when it rains, so that the charging gun can reduce the erosion of rainwater when in use, and increase the stability of the device when used outdoors.

[0052] At the same time, after the water baffle 4 is extended, when it rains, rainwater will enter the water baffle 4. Through the action of the lifting component 6, the top pressure plate 701 in the water baffle 4 will slide out. After sliding out, the top pressure plate 701 will support the vehicle body 1, thereby reducing the gap between the vehicle body 1 and the water baffle 4, so that rainwater cannot flow from the gap to the vicinity of the charging port, further reducing the erosion of rainwater and improving the rain protection ability.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
