Description
Technical Field
[0001] This utility model relates to the field of charging docks, and in particular to an automatic opening mechanism for the charging interface and a charging dock using the same. Background Technology
[0002] Charging equipment is a crucial component of new energy vehicles, such as charging docks installed on vehicles and charging guns connected to power supply equipment. Charging guns are plugged into the charging interface of the vehicle's charging dock to perform charging and discharging operations. To protect the safety of the charging interface, it is usually covered, and the cover is manually opened during charging. However, this has two drawbacks: First, manually opening and closing the cover is cumbersome for users, resulting in a poor user experience, and accidental operation or excessive force can easily damage the cover and the charging interface. Second, manual opening makes it unsuitable for charging environments and cannot be used in unmanned automatic charging scenarios. Utility Model Content

One end of the rotating shaft extends out of the hinge seat and is connected to the output shaft of the drive motor through the coupling. When the drive motor is started, it can drive the rotating shaft and the end cover to rotate at a set angle, so that the end ring of the end cover can be sealed and connected to the charging port or the end ring can be completely removed from the charging port for charging.
[0008] In some embodiments, the lower end of the rotating shaft is provided with an anti-rotation platform with a tangential structure, the first shaft hole of the rotating seat is an arc-shaped through hole and the inner wall is provided with a positioning chord surface, the lower end of the rotating shaft is interference-fitted into the first shaft hole, and the anti-rotation platform and the positioning chord surface are in contact.

The upper end of the rotational damping spring is attached to the inner wall of the hinge seat and the lower end is attached to the upper wall of the rotating seat; or the rotational damping spring is a torsion spring.

[0015] In some implementations, the rotation angle range of the drive motor is 90-270°;
[0016] The optimal rotation angle for the drive motor is 180°.
[0017] In some implementations, when the drive motor fails to start, applying force to the end cover can cause the shaft and the output shaft of the connected drive motor to rotate passively, disengaging the end ring from the charging port and enabling manual opening of the cover.
[0018] In some implementations, the charging port and the two hinges are integrally connected;
[0019] The hinge can be located at any of the left, right, and bottom sides of the rectangular panel of the charging dock body.

[0033] Figures 1 to 7 The diagram schematically illustrates an automatic charging interface opening mechanism and a charging dock using the same according to one embodiment of the present invention. As shown, the automatic charging interface opening mechanism includes: a charging dock body 1, an end cover 2, and a rotating module 01;
[0034] The charging base body 1 has an annular protruding charging port 11 at the front center and two hinge seats 12 at the upper and lower ends of its horizontal side.

[0037] This automatic opening and closing mechanism for the charging interface achieves automated opening and closing of the cover. Its advantages are: First, automatic opening and closing simplifies user operation, improves user experience, ensures precise and reliable operation with smooth movements, effectively protects the cover and electrical components inside the charging interface, and extends service life; Second, automatic opening and closing offers high adaptability to various charging environments, allowing it to be used in conjunction with automatic sensor-activated opening for unmanned charging gun scenarios; Third, the structure is simple and easy to install and assemble.

The lower end of the rotating shaft 3 is fitted with the first shaft hole 23, and the anti-rotation platform 31 and the positioning chord surface 24 are in close contact. Its beneficial effect is that this anti-rotation mechanism can achieve a reliable and stable connection position between the rotating shaft 3 and the rotating seat 22, maintain the set rotation angle for a long time, and prevent the displacement caused by the rotational misalignment of the rotating shaft 3.
[0039] Preferably, the lower end of the rotating shaft 3 is provided with an annular mounting groove 32, the rotating shaft 3 extends outward from the lower end hinge seat 12, and the locking piece 6 is fixedly connected to the mounting groove 32 and fits against the outer wall of the lower end hinge seat 12. Its advantages are: the structure is simple and easy to assemble.
[0040] Preferably, the locking piece 6 is a retaining ring. Its advantages are: retaining rings can improve the standardization of product parts and reduce product costs.
[0041] Preferably, a self-lubricating bearing or a deep groove ball bearing is also provided inside the first through hole 13, and the rotating shaft 3 is rotatably connected to the bearing. The beneficial effect is that this arrangement enables smooth rotation without any jamming or misalignment.
[0042] Furthermore, the length of the rotating seat 22 is less than the distance between the two hinge seats 12, and a rotational damping spring is also fitted on the rotating shaft 3. The upper end of the rotational damping spring is attached to the inner wall of the hinge seat 12, and the lower end is attached to the upper wall of the rotating seat 22; preferably, the rotational damping spring is a torsion spring. Its beneficial effect is that this setting, through the combination of mechanical and electric limiting, ensures high accuracy in positioning of the end cover 2.
[0043] Furthermore, the upper end of the coupling 4 has a connection hole 41 that is fixedly connected to the output shaft of the drive motor 5, and its lower end has a connection hole 41 that is fixedly connected to the coupling end 33 at the upper end of the rotating shaft 3.

The first threaded component 7 passes through the upper through hole 42, the first radial through hole 34 of the coupling end 33, or the second radial through hole of the output shaft to fix and connect to the threaded blind hole 43. Preferably, the upper through hole 43 is a countersunk hole or a stepped hole, and the first threaded component 7 is a Phillips head screw; the connecting holes 41 are all large arc blind holes, and both the coupling end 33 and the output shaft are provided with anti-rotation positioning surfaces.

Its advantages are: this mechanism allows for manual opening of the cover by rotating the end cover 2 when the drive motor 5 fails; therefore, this opening mechanism has both manual and automatic opening modes.
