The charging socket T is arranged on the lateral vehicle body of the electric motorcycle 1 and is located at a lower side of the seat cushion 26.
As shown in FIG. 1, the electric motorcycle 1 is provided with a vehicle body cover unit 3 that is set on and covers an external periphery of the vehicle frame unit 2. The vehicle body cover unit 3 comprises an upper vehicle body cover portion 31 set on and covering an upper side of the energy storage unit 22, a lower vehicle body cover portion 32 set on and covering a rear side and a lower side of the head tube portion 21, lateral vehicle body cover portions 33 set on and covering left and right lateral vehicle bodies of the vehicle body of the seat cushion 26 and the energy storage unit 22, rear vehicle body cover portions 34 set on and covering left and right lateral vehicle bodies of the vehicle body at a rear side of the seat cushion 26. A charging inlet 4 is arranged on lateral vehicle body cover portions 33 at a lower side of the seat cushion 26.
As shown in FIGS. 2, 3, 4, 5, 6, and 7, the charging inlet 4 comprises an inlet base 41. The inlet base 41 comprises a mounting cavity 411 that is arranged as a recess. A bottom of the mounting cavity 411 is formed with a through hole 412 penetrating therethrough. The charging socket T is arranged in the through hole 412. The charging socket T is electrically connected with the energy storage unit 22. The inlet base 41 is provided, in the mounting cavity 411, with an internal lid 42 that is pivotally mounted to cover and close the through hole 412. The internal lid 42 is provided with a sealing pad 42a. An external cover 43 is pivotally mounted in the mounting cavity 411 to close and cover the mounting cavity 411.
As shown in FIGS. 3, 4, 5, and 6, the mounting cavity 411 of the inlet base 41 is provided with an internal lid pivoting seat 413 adjacent to the through hole 412. One end of the internal lid 42 is provided with a pivoting portion 421, and a pivot axle P penetrates through the internal lid pivoting seat 413 and the pivoting portion 421 to have the end of the internal lid 42 pivotally mounted to the internal lid pivoting seat 413, so that the internal lid 42 is freely rotatable about a rotation center defined by the pivot axle P to thereby close or open the through hole 412. Further, an elastic element S is fit to the pivoting portion 421, and the present invention provides the elastic element S mounted on two sides of the pivoting portion 421 of the internal lid 42. Two ends of the elastic element S are respectively supported on or hooked on the pivoting portion 421 of the internal lid 42 or the mounting cavity 411, and as such, the elastic element S provides a pre-spring force on the pivoting portion 421. Another side of the internal lid 42 that is opposite to the pivoting portion 421 is provided, in a side edge, with a lifting portion 422. The lifting portion 422 is implemented in the present invention in the form of a raised curved rib. The internal lid 42 is further provided, at the side edge where the lifting portion 422 is provided, with a locking portion 423, and the locking portion 423 is implemented as a magnetically attracting member, and thus, the inlet base 41 is provided with a locking member 414 corresponding to the locking portion 423, and the locking member 414 is implemented as a magnetically attracted member. By means of magnetic attraction between the locking portion 423 and the locking member 414, a secure closure effect can be obtained for the internal lid 42 closing and covering the through hole 412. More specifically, the magnetic attraction force between the locking portion 423 and the locking member 414 is slightly greater than or equal to a spring-off force of the elastic element S, so that a user, when attempting to open the internal lid 42, only needs to use a finger to slightly lift the lifting portion 422, and the lifting force applied by the finger of the user is greater than the magnetic attraction force between the locking portion 423 and the locking member 414, and thus, the internal lid 42 can be easily lifted open, and the elastic element S may hold the internal lid 42 at a position of a predetermined degree of opening, by which the charging socket T is exposed for connection with the external power source to enable performance of a charging operation to the energy storage unit 22.
As shown in FIGS. 2, 3, 4, 5, and 7, the mounting cavity 411 of the inlet base 41 is provided with a plurality of external cover pivoting seats 415 adjacent to the internal lid pivoting seat 413. The plurality of external cover pivoting seats 415 are implemented as three such pivoting seats in the present invention, and the external cover pivoting seats 415 are arranged in a triangular configuration, meaning one at each of two sides of the internal lid pivoting seat 413 (up-down direction in the drawings) and one at right side (right side of left-right direction in the drawings). The external cover 43 is provided with a plurality of pivoting portions 431 corresponding to the plurality of external cover pivoting seats 415 of the inlet base 41. The plurality of pivoting portions 431 are also arranged in a triangular configuration as being corresponding to the plurality of external cover pivoting seats 415. Linking bars 432 are connected between the plurality of pivoting portions 431 and the plurality of external cover pivoting seats 415, meaning three such linking bars 432 are provided. Further, two of the three linking bars 432 are straight bars, while the remaining one is a curved bar. Each of the linking bars 432 has two ends respectively and rotatably connected to the pivoting portions 431 and the external cover pivoting seats 415, and specifically, the linking bars 432 are pivotally connected to the pivoting portions 431 and the external cover pivoting seats 415 by means of penetrating arrangement of pivot axles P1, so that the plurality of linking bars 432 take the pivot axles P1 at upper and lower ends as oscillation centers to drive the external cover 43 to lift from the mounting cavity 411 or to close and cover the mounting cavity 411. The linking bars 432 limit an opening degree of the external cover 43, namely after the external cover 43 is lifted open from the mounting cavity 411, the opening degree of the external cover 43 toward a vehicle body width direction does not exceed a width of the steering mechanism 212 in the vehicle body width direction. It is particularly noted that the plurality of linking bars 432 may form mutual constraining effect with respect to the mounting cavity 411 so that the external cover 43 can be secured and not shaking during an opening operation and the external cover 43 may have a final positioning effect after being opened. After the external cover 43 is lifted open from the mounting cavity 411, the internal lid 42 is exposed. A fastening mechanism M is arranged at one side of the external cover 43, so that the external cover 43 may securely close and cover the mounting cavity 411 by means of a fastening effect of the fastening mechanism M to thereby set the mounting cavity 411 in a closed condition to prevent external dust and moisture from entering the mounting cavity 411, and correspondingly, the user may operate and control the fastening mechanism M to release the fastened state to thereby allow the external cover 43 to be driven by the linking bars 432 to move a distance toward an outer side of the mounting cavity 411, and at this moment, the user may then push the external cover 43 toward one side and the external cover 43 takes the linking bars 432 as an oscillation center to translate toward one side of the vehicle body and no longer close and cover the mounting cavity 411, and as such, the external cover 43, after being opened, is transversely moved toward a lateral side of the vehicle body and then translate toward one side in the vehicle body front-rear direction to thereby expose the internal lid 42. A portion of the fastening mechanism M is arranged on the external cover 43, and another portion of the mechanism is arranged in the mounting cavity 411. The fastening mechanism M is implemented as a press-down snap mechanism or a solenoid mechanism, or a wire-controlled fastening mechanism in the present invention. When the external cover 43 closes and covers the mounting cavity 411, the external cover 43 forms a portion of the lateral vehicle body cover portions 33.
As shown in FIG. 8, an elastic element Si is fit to the pivot axles P1 pivoting the linking bars 432 and the external cover pivoting seats 415. In the present invention, the elastic element Si is mounted on the pivot axles P1 at the side of the external cover pivoting seats 415, and two ends of the elastic element Si are respectively supported on or hooked on the mounting cavity 411 or the linking bars 432, so that the elastic element Si provides a pre-spring force on the linking bars 432 to facilitates opening of the external cover 43.
