Description

Technical Field

[0001] This utility model relates to the field of charging protection technology, and in particular to an electric vehicle charging stand. 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 socket itself. However, with this design, users must manually perform multiple steps before charging—first opening the sheet metal cover, then manually unplugging the AC and DC dust covers in sequence before inserting the charging gun. After charging, users must follow a strict reset sequence: first manually closing the DC dust cover, then closing the AC dust cover, and finally closing the sheet metal cover. This complex process is inconvenient and reduces the efficiency and comfort of charging operations.

[0004] It is evident that the existing electric vehicle charging bases involve a rather cumbersome process of opening and closing the dust cover during charging operations. Utility Model Content

[0005] The purpose of this utility model is to provide an electric vehicle charging base that solves the problem that the opening and closing of the dust cover in existing electric vehicle charging bases is cumbersome during charging operations.

[0006] To achieve this objective, the present invention adopts the following technical solution: An electric vehicle charging base includes a flange and a body sheet metal cover. A DC charging terminal and an AC charging terminal are installed on the flange. The flange is provided with an opening and closing structure. The body sheet metal cover is inserted and closed with the AC charging terminal and is used to cover both the DC charging terminal and the AC charging terminal together. The opening and closing structure includes an opening and closing cover and an opening and closing motor. The opening and closing cover is slidably connected to the flange. The opening and closing motor is installed on the side of the flange opposite to the opening and closing cover. A transmission gear is rotatably connected to the flange. The opening and closing cover is provided with a rack that meshes with the transmission gear. The opening and closing motor is used to drive the transmission gear to rotate, so that the rack drives the opening and closing cover to move in a direction closer to or away from the DC charging terminal.

[0007] Optionally, the transmission gear has an integrally formed rotating shaft in the middle, the output shaft of the opening and closing motor is connected to a motor speed change assembly, the transmission shaft of the motor speed change assembly passes through the flange and is engaged with the rotating shaft; the opening and closing cover has a moving groove, and one end of the rotating shaft near the opening and closing cover is rotatably connected to the moving groove.

[0008] Optionally, there are two transmission gears and two racks, with each transmission gear corresponding to one rack. The two transmission gears mesh with each other, and the rotating shaft near the AC charging terminal is connected to the transmission shaft.

[0009] Optionally, the flange is provided with a first mounting groove, the flange is provided with a mounting plate, the mounting plate is provided with a second mounting groove corresponding to the first mounting groove, and the rotating shaft is rotatably connected in the first mounting groove and the second mounting groove.

[0010] Optionally, the flange is equipped with a first micro switch and a second micro switch that are arranged at a linear interval. The first micro switch is arranged adjacent to the DC charging terminal. The opening and closing cover is provided with a first protrusion for contacting and cooperating with the first micro switch and a second protrusion for contacting and cooperating with the second micro switch.

[0011] Optionally, the mounting plate is provided with a first limiting groove and a second limiting groove. The first limiting groove is used to limit the first micro switch to be mounted on the flange, and the second limiting groove is used to limit the second micro switch to be mounted on the flange.

[0012] Optionally, the mounting plate is provided with an integrally formed boss, and a locating pin is inserted into the flange to abut against the boss. The flange and the locating pin are locked together by a snap ring.

[0013] Optionally, the flange is provided with a mounting chamber for installing the opening and closing motor, and the flange is provided with a motor cover for sealing the mounting chamber. The motor cover is equipped with a sealing body for the motor lead wire of the opening and closing motor to pass through.

[0014] Optionally, the motor cover and the flange are locked together by self-tapping screws. The motor cover is provided with a third mounting groove, and a sealing gasket for sealing the mounting chamber is embedded in the third mounting groove.

[0015] Optionally, the body panel cover is provided with a cover portion and a snap-fit ​​portion. The cover portion is plugged into the AC charging terminal, and the snap-fit ​​portion is used to movably snap the body panel cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention provides an electric vehicle charging base. By incorporating an opening and closing structure and the meshing transmission of gears and racks, the cover automatically slides towards or away from the DC charging terminal, eliminating the need for manual opening of the DC dust cover. Opening the vehicle's sheet metal cover simultaneously opens the AC dust cover, significantly reducing the number of opening and closing steps required for charging and thus greatly improving the convenience and efficiency of the charging operation. The automated opening and closing design avoids the inconvenience of multiple manual operations, making it particularly suitable for scenarios requiring frequent charging (such as commercial logistics vehicles or daily commutes). It reduces operational complexity, making the charging process more intuitive and effortless, thereby increasing user satisfaction. Therefore, this invention solves the problem of cumbersome dust cover opening and closing steps in existing electric vehicle charging bases during charging operations. Attached Figure Description

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. 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.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model embodiment provides an electric vehicle charging dock, such as Figures 1 to 10 As shown, it includes a flange 10 and a body sheet metal cover 40. A DC charging terminal 20 and an AC charging terminal 30 are installed on the flange 10. An opening and closing structure 50 is provided on the flange 10. The body sheet metal cover 40 is inserted and closed with the AC charging terminal 30 and is used to cover the DC charging terminal 20 and the AC charging terminal 30 together. The opening and closing structure 50 includes an opening and closing cover 51 and an opening and closing motor 52. The opening and closing cover 51 is slidably connected to the flange 10. The opening and closing motor 52 is installed on the side of the flange 10 opposite to the opening and closing cover 51. A transmission gear 53 is rotatably connected to the flange 10. The opening and closing cover 51 is provided with a rack 511 that meshes with the transmission gear 53. The opening and closing motor 52 is used to drive the transmission gear 53 to rotate, so that the rack 511 drives the opening and closing cover 51 to move in a direction closer to or away from the DC charging terminal 20. In this embodiment, the opening and closing steps of the body sheet metal cover 40 can be realized manually or electrically, which will not be described in detail here. Both the DC charging terminal 20 and the AC charging terminal 30 are used to charge the electric vehicle. The DC charging terminal 20 and the AC charging terminal 30 are well-known structures in the art, and their specific structures will not be described in detail here.

[0025] It should be noted that this utility model provides an electric vehicle charging base. By setting an opening and closing structure 50, and cooperating with the meshing transmission of the transmission gear 53 and rack 511, the opening and closing cover 51 is automatically slidably controlled in the direction of approaching or moving away from the DC charging terminal 20. This eliminates the need to manually open the DC dust cover; opening the body sheet metal cover 40 simultaneously opens the AC dust cover, greatly reducing the opening and closing steps required for charging and thus significantly improving the convenience and efficiency of the charging operation. The automated opening and closing design avoids the inconvenience of multiple manual operations by the user, making it particularly suitable for scenarios with frequent charging (such as commercial logistics vehicles or daily commuting). It reduces operational complexity, making the charging process more intuitive and effortless, and improving user satisfaction. Therefore, this utility model solves the problem of the cumbersome opening and closing steps of the dust cover in existing electric vehicle charging bases during charging operations.

[0026] like Figures 3 to 10 As shown, the transmission gear 53 has an integrally formed rotating shaft 531 in the middle. The output shaft of the opening and closing motor 52 is connected to the motor speed change assembly 54. The transmission shaft 541 of the motor speed change assembly 54 passes through the flange 10 and is engaged with the rotating shaft 531. The opening and closing cover 51 has a moving groove 512, and the end of the rotating shaft 531 near the opening and closing cover 51 is rotatably connected to the moving groove 512. In this embodiment, the motor speed change assembly 54 is a known structure, and its specific structure will not be described in detail.

[0027] In practical implementation, the high-speed, low-torque output of the opening and closing motor 52 is converted by the motor speed change assembly 54 into the low-speed, high-torque output required to drive the opening and closing cover 51. This ensures that the opening and closing cover 51 has sufficient power during start-up, shutdown, and operation, resulting in smooth and reliable operation and avoiding problems such as jamming or insufficient power. Because the transmission gear 53 has an integrally formed rotating shaft 531 in the middle, the number of parts is reduced, avoiding additional assembly steps and potential loose connections, improving the rigidity and integrity of the structure, and making the transmission part more compact. The arrangement of the motor speed change assembly 54 and the transmission gear 53 makes full use of the space on the back side of the flange 10, achieving the integration of the drive system without occupying excessive external space, making the overall design of the charging base simpler and more compact.

[0028] The meshing of the rack 511 with the transmission gear 53 provides the driving tangential force; the end of the rotating shaft 531 is rotatably connected to the moving groove 512, providing a support point and guiding function. This constraint method effectively prevents the opening and closing cover 51 from warping, jamming, or detaching from the track due to unilateral force during sliding, ensuring that the opening and closing cover 51 always slides smoothly along the preset trajectory.

[0029] like Figures 3 to 5As shown, there are two transmission gears 53 and two racks 511. The transmission gears 53 and racks 511 correspond one-to-one, and the two transmission gears 53 mesh with each other. The rotating shaft 531 near the AC charging terminal 30 is connected to the transmission shaft 541.

[0030] In practical implementation, through the corresponding arrangement of two gears and two racks 511, both sides of the opening and closing cover 51 are driven simultaneously. This changes the situation where only one side is driven while the other side passively follows, ensuring that the force on the opening and closing cover 51 is completely balanced during movement. This effectively eliminates the twisting, vibration, or noise caused by unilateral force, achieving smooth sliding of the opening and closing cover 51. The power of the opening and closing motor 52 is first transmitted to the rotating shaft 531 near the AC charging terminal 30, causing one of the transmission gears 53 to rotate, which in turn drives the other transmission gear 53 meshing with it. The output torque of the opening and closing structure 50 is effectively amplified.

[0031] like Figure 4 As shown, the flange 10 is provided with a first mounting groove 11, and a mounting plate 55 is mounted on the flange 10. The mounting plate 55 is provided with a second mounting groove 551 corresponding to the first mounting groove 11. The rotating shaft 531 is rotatably connected in the first mounting groove 11 and the second mounting groove 551.

[0032] In practical implementation, the first mounting groove 11 and the second mounting groove 551 securely wrap and constrain the rotating shaft 531 in the correct position, providing it with stable support in both the circumferential and axial directions. This greatly enhances the rigidity of the transmission system and effectively resists the radial force and potential vibration generated during the meshing of the transmission gear 53. The first mounting groove 11 and the second mounting groove 551 are designed and machined with strict alignment, ensuring that the rotating shaft 531 can be precisely positioned on the preset axis. This guarantees that the transmission gear 53 and the rack 511 on the opening / closing cover 51 are in the optimal meshing position, avoiding problems such as poor meshing, increased wear, or operating noise caused by support point deviations. The separate mounting method of the flange 10 and the mounting plate 55 significantly reduces machining difficulty and cost compared to directly machining a complex deep hole or bearing housing on a single part.

[0033] like Figures 3 to 5 As shown, a first micro switch 561 and a second micro switch 562 are installed on the flange 10 at linear intervals. The first micro switch 561 is arranged adjacent to the DC charging terminal 20. The opening and closing cover 51 is provided with a first protrusion 513 for contacting and cooperating with the first micro switch 561 and a second protrusion 514 for contacting and cooperating with the second micro switch 562.

[0034] In practical implementation, by setting a first microswitch 561 and a second microswitch 562, with the first microswitch 561 corresponding to the fully closed position and the second microswitch 562 corresponding to the fully open position, the exact state of the open / closed cover 51 can be sensed in real time and accurately. This provides crucial feedback signals to controllers known in the art, enabling them to determine whether the opening / closing action has been performed correctly. When the open / closed cover 51 moves to its limit position (fully open or fully closed), the corresponding protrusion triggers the microswitch, which immediately sends an electrical signal to the controller. The controller then immediately cuts off the power to the opening / closing motor 52, stopping it from operating. This avoids overheating damage or mechanical component overload caused by the opening / closing motor 52 remaining powered due to stalling at the end of its stroke, and also provides a clear starting point for executing the next movement in the opposite direction. This design achieves closed-loop control of the opening / closing process, going beyond simply issuing action commands to confirming the completion of the action. For example, after the user initiates a charging command, the body panel cover 40 opens, then drives the opening and closing cover 51 to open. After the second micro switch 562 is triggered and it is confirmed that the opening and closing cover 51 is fully open, a prompt to the user is issued saying "Please insert the charging gun", thereby preventing the charging gun from being difficult to plug or unplug or damaged due to the opening and closing cover 51 not being fully open.

[0035] like Figures 3 to 10 As shown, the mounting plate 55 is provided with a first limiting groove 552 and a second limiting groove 553. The first limiting groove 552 is used to limit the first micro switch 561 to be mounted on the flange 10, and the second limiting groove 553 is used to limit the second micro switch 562 to be mounted on the flange 10.

[0036] In practical implementation, the first limiting groove 552 and the second limiting groove 553 ensure that both the first microswitch 561 and the second microswitch 562 can be quickly and accurately placed into their predetermined unique positions, thereby guaranteeing that the relative positions of their trigger points with the first protrusion 513 and the second protrusion 514 remain consistent. During assembly, the operator does not need to perform tedious manual adjustments or use complex tooling to position the microswitches. Initial positioning is achieved simply by embedding or pressing the microswitch against the limiting groove. This simplifies and clarifies the assembly process, significantly reducing reliance on manual skills and improving assembly efficiency and consistency on the production line.

[0037] like Figures 5 to 8 As shown, the mounting plate 55 has an integrally formed boss 554, and the flange 10 has a locating pin 571 inserted into it to abut against the boss 554. The flange 10 and the locating pin 571 are locked together by a snap ring 572. In this embodiment, the number of bosses 554 is set to two.

[0038] In practice, the mounting plate 55 is quickly and accurately positioned on the flange 10 by the contact between the boss 554 and the locating pin 571. Since the flange 10 and the locating pin 571 are locked together by the snap ring 572, displacement of the mounting plate 55 during operation of the opening / closing structure 50 is prevented, ensuring smooth rotation of the transmission gear 53. The locating pin 571 bears the main vibration load. Together with the snap ring 572 and the boss 554, the locating pin 571 forms a vibration-resistant mechanical locking unit, solving the problem of accuracy attenuation caused by vibration.

[0039] like Figures 1 to 10 As shown, flange 10 has a mounting chamber (not shown) for mounting the opening and closing motor 52. Flange 10 also has a motor cover 58 for sealing the mounting chamber. A sealing body 581 is mounted on the motor cover 58 for the motor lead wire 521 of the opening and closing motor 52 to pass through. The motor cover 58 and flange 10 are locked together by self-tapping screws 59. The motor cover 58 has a third mounting groove 582, into which a sealing gasket 583 is embedded for sealing the mounting chamber. In this embodiment, the sealing body 581 can be a rubber sealing plug.

[0040] In practical implementation, the motor cover 58 allows the opening and closing motor 52 to be enclosed and installed within the flange 10. When the motor cover 58 is tightened with the self-tapping screws 59, the sealing gasket 583 is compressed, forming a reliable elastic sealing ring at the mating surface between the motor cover 58 and the flange 10, effectively preventing external moisture and dust from entering the installation chamber. The wire sealing body 581 allows the motor lead 521 to pass through and tightly wraps around it, solving the sealing problem at the wire harness opening.

[0041] like Figures 1 to 3 As shown, the body sheet metal cover 40 is provided with a cover part 41 and a snap-fit ​​part 42. The cover part 41 is plugged into the AC charging terminal 30, and the snap-fit ​​part 42 is used to snap the body sheet metal cover 40 into place.

[0042] In practical implementation, because the cover part 41 and the AC charging terminal 30 are plugged into each other, it ensures that the body panel cover 40 can accurately align with and cover the AC charging terminal 30 when closed. This tight plugging not only serves a positioning function but also effectively prevents moisture and dust from entering the AC charging terminal 30 through the gaps in the cover, thus improving the protection level of the charging interface. In traditional designs, the body panel cover 40 may simply be a simple cover, while the AC terminal dust cover is separate. This design integrates the functions of the external cover and the internal dust cover into a single component, the body panel cover 40. The cover part 41 directly undertakes the sealing and protection of the AC charging terminal 30, thereby eliminating the need for a separate plastic dust cover and simplifying the number of parts inside the assembly. Traditional designs require three steps: opening the vehicle hood, manually removing the AC dust cover, and manually removing the DC dust cover. This design combines the functions of the vehicle body panel cover 40 and the AC dust cover into one, allowing the AC charging port to be automatically exposed when the user opens the vehicle body panel cover 40 in the first step. This reduces the operation steps from three to two, significantly improving the efficiency of the charging operation.

[0043] Working Principle: This utility model provides an electric vehicle charging base. By setting an opening and closing structure 50, and cooperating with the meshing transmission of the transmission gear 53 and rack 511, the opening and closing cover 51 is automatically slidably controlled along the direction of approaching or moving away from the DC charging terminal 20. This eliminates the need to manually open the DC dust cover; opening the vehicle body sheet metal cover 40 simultaneously opens the AC dust cover, greatly reducing the opening and closing steps required for charging and significantly improving the convenience and efficiency of the charging operation. The automated opening and closing design avoids the inconvenience of multiple manual operations by the user, making it particularly suitable for scenarios with frequent charging (such as commercial logistics vehicles or daily commuting). It reduces operational complexity, making the charging process more intuitive and effortless, and improving user satisfaction. Therefore, this utility model solves the problem of the cumbersome opening and closing steps of the dust cover in existing electric vehicle charging bases during charging operations.

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.
