Automobile charging port box structure

Abstract

This utility model relates to the field of automotive charging technology, specifically to a structure for an automotive charging port box. Through the elastic connection between a telescopic spring and a sealing strip, external pressure is applied when the charging port cover is closed, squeezing the telescopic spring and causing the sealing strip to retract into the mounting groove. After the charging port cover is fully closed, the telescopic spring loses external pressure, causing the sealing strip to pop out. Thus, the telescopic spring squeezes the sealing strip to seal the edge of the charging port cover, preventing rainwater or dust from entering the charging port and avoiding damage to the charging port box, thereby extending its service life. The arc angle on the sealing strip facilitates pressure being applied to the sealing strip when the charging port cover is closed, causing it to retract and preventing interference with the closure of the charging port cover. When energized, the electromagnet generates magnetic force, which magnetically attracts and fixes the charging port cover, preventing it from suddenly opening when closed. Operators can easily control the opening and closing of the charging port cover by controlling the on / off state of the electromagnet.

Description

Technical Field

[0001] This utility model relates to the field of automotive charging technology, and in particular to a structure for an automotive charging port box. Background Technology

[0002] Electric vehicles are favored by governments around the world due to their environmental friendliness. The construction of charging stations and the standardization of charging standards have made charging electric vehicles more convenient. Electric vehicles are usually equipped with fast charging stations and slow charging stations to meet consumers' needs for fast and slow charging. With the popularization of electric vehicles, the charging port, as a key component for power transmission, directly affects the safety and reliability of charging due to its box structure.

[0003] Existing patent application publication number CN213799925U discloses a charging port cover structure for an electric vehicle, including a charging port box and a charging port cover. The charging port box is fixedly installed on the vehicle body. The bottom of the charging port box has a charging through hole communicating with the vehicle's charging port. A mounting base is provided on one side of the charging port box. A rotating arm is provided on the charging port cover. One end of the rotating arm is installed on the mounting base through a pin. The rotating arm can rotate freely around the pin. A locking pin is provided on the inner wall of the charging port box. An elastic clip matching the locking pin is fixedly installed on the bottom surface of the charging port cover. The charging port cover can be opened and closed to seal the opening of the charging port box through the matching of the elastic clip and the locking pin. An opening handle is provided on the outer surface of the charging port cover. This utility model has a simple structure, is easy to use, reduces the use of parts, and lowers the cost of parts and assembly.

[0004] However, the car charging port cover has poor sealing. When the vehicle is in a rainstorm or dusty environment, liquid and dust may enter around the charging port through gaps, which will reduce the safety and reliability of the charging port. Utility Model Content

[0005] The purpose of this utility model is to provide a car charging port box structure that solves the problem that when a vehicle is in a rainstorm or sandstorm environment, liquid and sand may enter around the charging port through gaps, thereby reducing the safety and reliability of the charging port.

[0006] To achieve the above objectives, this utility model provides a car charging port box structure, including a car body, a charging port box is provided at the outer end of the car body, a charging port cover is hinged to the outside of the charging port box, and three mounting slots are provided inside the charging port box. The charging port box and the charging port cover can be closed together, thereby closing the charging port box through the charging port cover.

[0007] It also includes waterproof and dustproof components;

[0008] The waterproof and dustproof component includes telescopic springs. Several telescopic springs are evenly arranged inside the three mounting slots. Each of the telescopic springs has a sealing strip near one end of the charging port box. The sealing strip is made of elastic sealing material. Through the elastic connection between the telescopic spring and the sealing strip, when the charging port cover is closed, external pressure is applied to squeeze the telescopic spring and cause the sealing strip to retract into the mounting slot. When the charging port cover is fully closed, the telescopic spring loses external pressure and causes the sealing strip to pop out. Thus, the sealing strip is sealed to the edge of the charging port cover by the telescopic spring, which can prevent rainwater or sand from entering the charging port.

[0009] The charging port box has a fast charging port inside and a slow charging port on one side of the fast charging port. An electromagnet is located at the lower end of the charging port box and is located on one side of the mounting slot. The electromagnet can be magnetically connected to the charging port cover. The fast charging port and slow charging port allow users to choose between fast charging and slow charging according to their needs. When the electromagnet is energized, it generates a magnetic force to magnetically attract and fix the charging port cover, preventing the charging port cover from suddenly opening when closed. The operator can control the opening and closing of the charging port cover by controlling the on and off of the electromagnet.

[0010] Both the fast charging port and the slow charging port are equipped with charging guide blocks on their outer sides, and a buffer pad is provided at the inner end of the charging guide block. The buffer pad is made of silicone. The charging guide block facilitates the insertion of the charging gun, making it easy to insert the charging gun quickly and preventing incorrect insertion. The buffer pad provides cushioning force to prevent the charging gun from hitting the charging guide block directly and causing damage.

[0011] The three mounting slots are respectively located at the left and right ends and the bottom of the charging port box. The positions of the three mounting slots match the corresponding three sides of the charging port cover. The width of the mounting slots is slightly larger than the width of the sealing strip. The length and width of the three sealing strips are the same as the length and width of the corresponding three sides of the charging port cover. The end of each of the three sealing strips near the opening of the charging port box is provided with an arc corner. The arc corner on the sealing strip facilitates the application of pressure to the sealing strip when the charging port cover is closed, causing the sealing strip to contract and avoiding affecting the closing of the charging port cover.

[0012] The charging guide block is conical in shape, and the diameter of the end of the charging guide block away from the fast charging port and the slow charging port is larger than the diameter of the end closer to the fast charging port and the slow charging port.

[0013] This utility model discloses a car charging port box structure. During use, the charging port box and charging port cover can be closed together. The charging port box is closed via the cover. An elastic connection between a telescopic spring and a sealing strip allows external pressure to be applied when the cover closes, compressing the telescopic spring and causing the sealing strip to retract into the mounting groove. After the cover is fully closed, the telescopic spring releases external pressure, causing the sealing strip to pop out. This, combined with the spring's compression of the sealing strip, creates a sealed connection between the sealing strip and the edge of the cover, preventing rainwater or dust from entering the charging port and avoiding damage to the charging port box, thus extending its service life. The arc angle on the sealing strip facilitates pressure application to the sealing strip when the cover closes, causing it to retract and preventing interference with the cover's closure. An electromagnet, when energized, generates magnetic force to magnetically attract and fix the charging port cover, preventing it from suddenly opening when closed. Operators can easily control the opening and closing of the charging port cover by controlling the on / off state of the electromagnet. Attached Figure Description

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1-4 This utility model provides a technical solution:

[0022] A car charging port box structure includes a car body 1, a charging port box 2 is provided at the outer end of the car body 1, a charging port cover 3 is hinged to the outside of the charging port box 2, and three mounting slots 4 are provided inside the charging port box 2. The charging port box 2 and the charging port cover 3 can be closed together, thereby closing the charging port box 2 through the charging port cover 3.

[0023] It also includes waterproof and dustproof components;

[0024] The waterproof and dustproof component includes telescopic springs 5. Several telescopic springs 5 ​​are evenly arranged inside the three mounting slots 4. Each of the telescopic springs 5 ​​has a sealing strip 6 near one end of the charging port box 2. The sealing strip 6 is made of elastic sealing material. Through the elastic connection between the telescopic springs 5 ​​and the sealing strip 6, when the charging port cover 3 is closed, external pressure is applied to squeeze the telescopic springs 5 ​​and cause the sealing strip 6 to retract into the mounting slot 4. When the charging port cover 3 is completely closed, the telescopic springs 5 ​​lose external pressure and cause the sealing strip 6 to pop out. Thus, the sealing strip 6 is sealed to the edge of the charging port cover 3 by the telescopic springs 5, which can prevent rainwater or sand from entering the charging port.

[0025] In this embodiment, the charging port box 2 preferably has a fast charging port 7 inside and a slow charging port 8 on one side of the fast charging port 7. An electromagnet 9 is provided at the lower end of the charging port box 2. The electromagnet 9 is located on one side of the mounting slot 4. The electromagnet 9 can be magnetically connected to the charging port cover 3. The fast charging port 7 and the slow charging port 8 make it convenient for users to choose fast charging or slow charging according to their needs. When the electromagnet 9 is energized, it can generate magnetic force to magnetically attract and fix the charging port cover 3, preventing the charging port cover 3 from suddenly opening when closed. The operator can control the opening and closing of the charging port cover 3 by controlling the power supply of the electromagnet 9.

[0026] In this embodiment, preferably, a charging guide block 10 is provided on the outer side of both the fast charging port 7 and the slow charging port 8. A buffer pad 11 is provided on the inner end of the charging guide block 10. The buffer pad 11 is made of silicone. The charging guide block 10 facilitates the insertion of the charging gun, making it easy to insert the charging gun quickly and preventing incorrect insertion. The buffer pad 11 can provide cushioning force to prevent the charging gun from hitting the charging guide block 10 directly and causing damage.

[0027] In this embodiment, the three mounting grooves 4 are preferably located at the left and right ends and the bottom end of the charging port box 2. The positions of the three mounting grooves 4 and the corresponding three sides of the charging port cover 3 are matched. The width of the mounting groove 4 is slightly larger than the width of the sealing strip 6. The length and width of the three sealing strips 6 are the same as the length and width of the corresponding three sides of the charging port cover 3. The end of the three sealing strips 6 near the opening of the charging port box 2 is provided with an arc corner. The arc corner on the sealing strip 6 makes it easier to apply pressure to the sealing strip 6 when the charging port cover 3 is closed, so as to cause the sealing strip 6 to contract and avoid affecting the closing of the charging port cover 3.

[0028] In this embodiment, the preferred shape of the charging guide block 10 is a cone shape, and the diameter of the end of the charging guide block 10 away from the fast charging port 7 and the slow charging port 8 is larger than the diameter of the end closer to the fast charging port 7 and the slow charging port 8.

[0029] Working principle:

[0030] During use, the electromagnet 9 is de-energized, thereby opening the charging port cover 3. The fast charging port 7 and slow charging port 8 allow users to choose between fast or slow charging as needed. The charging guide block 10 guides the charging gun for quick insertion and prevents incorrect placement. The buffer pad 11 provides cushioning to prevent damage from direct impact with the charging guide block 10. After charging is complete, the charging gun can be removed and the charging port cover 3 closed. The elastic connection between the telescopic spring 5 and the sealing strip 6 applies external pressure when the charging port cover 3 is closed, squeezing the telescopic spring 5 and causing the sealing strip 6 to retract into place. Inside the slot 4, after the charging port cover 3 is closed, the telescopic spring 5 loses external pressure and causes the sealing strip 6 to pop out. Thus, the telescopic spring 5 squeezes the sealing strip 6 to seal the edge of the charging port cover 3, which can prevent rainwater or sand from entering the charging port and avoid damage to the charging port box 2, thereby extending its service life. The arc angle on the sealing strip 6 makes it easy to apply pressure to the sealing strip 6 when the charging port cover 3 is closed, causing the sealing strip 6 to contract and avoid affecting the closing of the charging port cover 3. Then, the electromagnet 9 is energized. After being energized, the electromagnet 9 can generate magnetic force, which can magnetically attract and fix the charging port cover 3, preventing the charging port cover 3 from suddenly opening when it is closed.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
