Description

Technical Field

[0001] This utility model relates to the field of charging technology for charging docks, and in particular to a charging dock with an automatic opening and closing cover. Background Technology

[0002] With the increasing popularity of electric vehicles globally, especially in mainstream markets such as Europe, charging interfaces using the CCS2 (Combined Charging System Type 2) standard have become standard equipment for various electric passenger vehicles, commercial logistics vehicles, and trucks. The dust cover of the charging dock, as a key component ensuring the safety, reliability, and durability of the charging interface, directly impacts the user experience and the long-term performance of the charging system.

[0003] In existing technologies, most vehicles equipped with CCS2 charging interfaces typically employ the following traditional dustproof system design: First, a separate sheet metal cover is installed on the vehicle body; second, separate pluggable dust covers are provided for the AC and DC terminals on the charging dock itself. However, during charging, the vehicle body cover must be manually opened before the pluggable dust covers on the charging dock can be opened, making the opening process for the charging dock rather cumbersome.

[0004] It is evident that the existing charging dock technology suffers from a rather cumbersome process of opening the cover. Utility Model Content

[0005] The purpose of this invention is to provide a charging dock with an automatic opening and closing cover, which solves the problem that the opening steps of the cover in existing charging docks are relatively cumbersome.

[0006] To achieve this objective, the present invention adopts the following technical solution: A charging base with an automatic opening and closing cover includes a flange on which AC terminals and DC terminals are mounted in a layered manner. A vehicle body cover for plugging into and closing with the AC terminals is mounted on the flange. A flip-up assembly is connected to the flange. The flip assembly includes a charging flip cover and a flip motor. The charging flip cover is hinged to the flange and is used to close the DC terminal. The flip motor is located on the side of the flange opposite to the charging flip cover. The flip motor is used to drive the charging flip cover to flip in a direction close to or away from the DC terminal so that the charging flip cover closes or exposes the DC terminal.

[0007] Optionally, the flip assembly further includes a crank pin and a moving block. The moving block has a moving groove arranged in an elongated shape. One end of the crank pin is rotatably connected to the charging flip cover, and the other end of the crank pin is inserted into the moving groove. The flip motor is used to drive the moving block to move in a direction closer to or away from the flange, so that the crank pin drives the charging flip cover to flip.

[0008] Optionally, a first retaining ring is installed on the crank pin to limit the crank pin to be installed on the charging flip cover, and the moving block is provided with a mounting hole, and the power rod of the flip motor passes through the flange and is engaged with the mounting hole.

[0009] Optionally, the charging flip cover includes a dust cover hinged to the flange, the crank pin is mounted on the dust cover, and a DC end rubber cover that is plugged into the dust cover is adhered to the dust cover.

[0010] Optionally, a locating pin is fastened to the flange and is diagonally arranged to the crank pin. The dust cover is rotatably connected to the locating pin, and a second retaining ring is installed on the locating pin for limiting the installation of the dust cover.

[0011] Optionally, the power rod is fitted with a sealing ring and a pressure plate for pressing the sealing ring, and the pressure plate is fastened to the flange.

[0012] Optionally, the vehicle body cover is provided with a sealing cover and a snap-fit ​​part, the sealing cover is inserted and sealed with the AC terminal, and the snap-fit ​​part is snap-fitted with the flange.

[0013] Optionally, the sealing cap is fastened to the vehicle body cover by screws, and the vehicle body cover and the snap-fit ​​part are integrally formed.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides an automatic opening and closing charging base. Because the vehicle body cover is plugged into and closed with the AC terminals, opening the cover exposes the AC terminals simultaneously, reducing the steps required for opening and closing traditional AC dust covers. A flip motor drives the charging cover to rotate in a direction closer to or further away from the DC terminals, thus automatically opening and closing the cover. Users do not need to manually operate the cover during charging, significantly simplifying the charging process and improving convenience and user experience. Since the flip motor is located on the side of the flange opposite the charging cover, the charging base has a reasonable layout, which helps optimize the internal space structure and makes the overall design more compact.

[0019] To make the utility model's objectives, features, and advantages more apparent and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model embodiment provides a charging dock with an automatically opening and closing cover, such as... Figures 1 to 9 As shown, it includes a flange 10, on which AC terminals 20 and DC terminals 30 are installed in a layered manner, and a body cover 40 for plugging and sealing with the AC terminals 20 is installed on the flange 10. A flip assembly 50 is connected to the flange 10. The flip assembly 50 includes a charging flip cover 51 and a flip motor 52. The charging flip cover 51 is hinged to the flange 10 and is used to close the DC terminal 30. The flip motor 52 is disposed on the side of the flange 10 opposite to the charging flip cover 51. The flip motor 52 is used to drive the charging flip cover 51 to flip in a direction closer to or away from the DC terminal 30, so that the charging flip cover 51 closes or exposes the DC terminal 30. In this embodiment, the opening and closing of the vehicle body cover 40 can be achieved manually or by a motor.

[0023] It should be noted that the automatic opening and closing charging base provided by this utility model, since the vehicle body cover 40 is plugged and closed with the AC terminal 20, can expose the AC terminal 20 at the same time as opening the vehicle body cover 40, reducing the opening and closing steps of the traditional AC dust cover. The charging flip cover 51 is driven by the flip motor 52 to flip along the direction closer to or further away from the DC terminal 30, so that the charging flip cover 51 closes or exposes the DC terminal 30, realizing the automatic opening and closing of the charging flip cover 51. Users do not need to manually operate the charging flip cover 51 during charging, significantly simplifying the charging operation steps and improving the convenience and user experience. Since the flip motor 52 is arranged on the side of the flange 10 opposite to the charging flip cover 51, the layout of the charging base is reasonable, which helps to optimize the internal space structure of the charging base, making the overall design more compact.

[0024] like Figures 1 to 9 As shown, the flip assembly 50 also includes a crank pin 53 and a moving block 54. The moving block 54 has a moving groove 541 arranged in an elongated shape. One end of the crank pin 53 is rotatably connected to the charging flip cover 51, and the other end of the crank pin 53 is inserted into the moving groove 541. The flip motor 52 is used to drive the moving block 54 to move in a direction close to or away from the flange 10, so that the crank pin 53 drives the charging flip cover 51 to flip.

[0025] In practical implementation, when the charging flip cover 51 needs to be opened, the flip motor 52 drives the moving block 54 to move away from the flange 10, which in turn moves the crank pin 53, causing the charging flip cover 51 to flip, thus achieving automatic opening of the charging flip cover 51. Conversely, the flip motor 52 drives the moving block 54 to move towards the flange 10, which in turn moves the crank pin 53, causing the charging flip cover 51 to flip, thus achieving automatic closing of the charging flip cover 51. By setting a long, narrow moving groove 541, clearance space is provided for the movement of the crank pin 53, preventing movement interference and ensuring the automatic opening and closing of the charging flip cover 51.

[0026] like Figures 2 to 9 As shown, a first retaining ring 55 is installed on the crank pin 53 to limit the crank pin 53 to be installed on the charging flip cover 51. The moving block 54 is provided with a mounting hole 542. The power rod 521 of the flip motor 52 passes through the flange 10 and is engaged with the mounting hole 542.

[0027] In practical implementation, two first retaining rings 55 are used. These two first retaining rings 55 allow for quick and secure mounting of the crank pin 53 onto the charging flip cover 51. The mounting hole 542 facilitates the engagement of the power rod 521 onto the moving block 54. Through the motion transmission between the crank pin 53 and the moving block 54, the extension and retraction motion of the power rod 521 is converted into the flipping motion of the charging flip cover 51. This ensures that the movement trajectory of the charging flip cover 51 during opening and closing is stable and controllable, avoiding the risk of incomplete action or jamming, and improving the accuracy and reliability of automated operation.

[0028] like Figures 1 to 9 As shown, the charging flip cover 51 includes a dust cover 511 hinged to the flange 10, a crank pin 53 mounted on the dust cover 511, and a DC end rubber cover 512 bonded to the dust cover 511 for insertion into the DC terminal 30. A positioning pin 56 diagonally opposite to the crank pin 53 is fastened to the flange 10, and the dust cover 511 is rotatably connected to the positioning pin 56. A second retaining ring 57 for limiting the installation of the dust cover 511 is mounted on the positioning pin 56.

[0029] In practice, a DC end rubber cover 512 is bonded to the dust cover 511, allowing it to elastically deform and form a tight seal when inserted into the DC terminal 30. This soft sealing method effectively isolates water, dust, and other contaminants, significantly improving the safety and reliability of the DC terminal 30 during long-term use. Since the positioning pin 56 and crank pin 53 are diagonally arranged, they provide stable support on both sides of the charging flip cover 51. This diagonally arranged fulcrum structure balances the forces acting on the charging flip cover 51 during opening and closing, effectively preventing the charging flip cover 51 from shaking or jamming, and ensuring the smooth flipping motion of the charging flip cover 51.

[0030] like Figure 2 As shown, the power rod 521 is fitted with a sealing ring 58 and a pressure plate 59 for pressing the sealing ring 58. The pressure plate 59 is fastened to the flange 10.

[0031] In practice, by attaching a sealing ring 58 to the power rod 521 of the flip motor 52 and pressing the sealing ring 58 with a pressure plate 59, an effective dynamic sealing barrier is formed between the power rod 521 and the flange 10. This effectively prevents water vapor, dust and other pollutants from entering the charging base through the movement gap of the power rod 521, thereby protecting the AC terminal 20, DC terminal 30 and the flip motor 52 inside the charging base, and ensuring that the charging base can work stably for a long time even in harsh environments.

[0032] like Figure 1 and Figure 2As shown, the vehicle body cover 40 is provided with a sealing cover 41 and a snap-fit ​​part 42. The sealing cover 41 is inserted and sealed to the AC terminal 20, and the snap-fit ​​part 42 is snap-fitted to the flange 10. The sealing cover 41 and the vehicle body cover 40 are fastened together by screws, and the vehicle body cover 40 and the snap-fit ​​part 42 are integrally formed structures.

[0033] In practical implementation, a sealing cover 41, which is inserted and sealed to the AC terminal 20, ensures the airtightness of the AC interface when not charging, effectively preventing the intrusion of moisture, dust, and other foreign objects, thus ensuring the safety and reliability of the charging interface. Simultaneously, the snap-fit ​​engagement between the snap-fit ​​part 42 and the flange 10 enables quick positioning and secure fixing of the body cover 40 on the flange 10, forming a stable and reliable installation structure. Since the sealing cover 41 and the body cover 40 are fastened together with screws, this detachable design facilitates independent replacement or maintenance when the sealing cover 41 wears or ages due to long-term use. It eliminates the need to replace the entire body cover 40, significantly reducing subsequent maintenance costs and repair complexity.

[0034] Working Principle: This utility model provides an automatic opening and closing charging base. Since the vehicle body cover 40 is plugged into and closed with the AC terminal 20, opening the vehicle body cover 40 exposes the AC terminal 20, reducing the opening and closing steps of traditional AC dust covers. The charging flip cover 51 is driven by the flip motor 52 to flip along the direction closer to or further away from the DC terminal 30, thus automatically opening and closing the charging flip cover 51. Users do not need to manually operate the charging flip cover 51 during charging, significantly simplifying the charging operation and improving convenience and user experience. Because the flip motor 52 is located on the side of the flange 10 opposite to the charging flip cover 51, the layout of the charging base is reasonable, helping to optimize the internal space structure and making the overall design more compact.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
