Example two

The embodiment further provides a power assisting box 2, which can be used in cooperation with the charging pile 1 in the first embodiment, as shown in fig. 1 to 5, the power assisting box 2 includes a box body 21, a winding mechanism 22 and an auxiliary rope 23.

Wherein, the surface of box body 21 is equipped with second limit structure 211, and second limit structure 211 mutually supports with first limit structure 12 to make box body 21 can slide in first slide 111. Winding mechanism 22 sets firmly in box body 21, and supplementary rope 23 rolls up on winding mechanism 22, and the one end of supplementary rope 23 is worn out box body 21 for with fill electric pile device charging cable 3 or charge rifle 7 and be connected. The winding mechanism 22 can drive the auxiliary rope 23 to retract. Specifically, the other end of the auxiliary rope 23 is connected to the winding mechanism 22, and the winding mechanism 22 can cooperate with the auxiliary rope 23 to switch the auxiliary rope 23 between the locked state and the retracted state, and in the case where the auxiliary rope 23 is in the retracted state, the winding mechanism 22 can provide a retracting force for retracting the auxiliary rope 23 into the case 21 to wind the auxiliary rope 23 around the winding mechanism 22.

The operating principle and specific structure of the winding mechanism 22 in this embodiment may be various, and the winding mechanism 22 having the following two structures is provided in this embodiment.

In one configuration of the winding mechanism 22, the winding mechanism 22 includes a winding roll 221, a driving motor, an electromagnetic locking element, and a trigger switch. Wherein, the auxiliary rope is wound on the winding roll 221, and the driving motor is connected to the winding roll 221 in a driving manner and is used for driving the winding roll 221 to rotate so as to wind the auxiliary rope 23. The electromagnetic locking element is fixed in the box body 21 and is abutted against the outer side wall of the winding roll 221, and the touch switch is used for controlling the state of the electromagnetic locking element. When the winding roll 221 needs to be locked, the telescopic column of the electromagnetic locking piece is controlled to extend out through the touch switch and abuts against the outer side wall of the winding roll 221, so that the winding roll 221 cannot rotate continuously; when the winding roll 221 is required to rotate, the telescopic column of the battery locking piece is controlled to retract through the touch switch, so that the locking of the winding roll 221 is released, and the winding roll 221 can be driven to rotate by pulling the auxiliary rope or driving the motor. The touch switch can be controlled by the electronic equipment fixed on the charging pile 1, and a user sends a control instruction to the touch switch through the electronic equipment.

In another structure of the winding mechanism 22, the winding mechanism 22 includes a coil spring, a wire spool 221, and balls. The auxiliary rope 23 is wound on the winding roll 221, and the winding roll 221 is rotatably disposed in the box body 21 to realize the winding and unwinding of the auxiliary rope 23. A seating chamber is formed in the winding roll 221, and the coil spring is disposed in the seating chamber to provide a first winding force to the winding roll 221. Furthermore, a limiting groove is further formed in the winding roll 221, a groove corresponding to the limiting groove is formed in the inner wall of the box body 21, and the balls are movably arranged between the limiting groove and the groove of the box body 21. Further for the realization to the card of ball position, the inner wall of box body 21 still is equipped with ball card groove and arc and lacks the groove, and ball card groove and slot adjacent setting for to ball card position, arc lack the groove and are bordered with ball card groove, and it is bordered with the end of slot simultaneously, are used for restricting the roll position of ball on box body 21. The overall structure and principle of the winding mechanism 22 are similar to those of the winding device widely used for data line contraction, cable line 7 contraction, etc., and therefore, the details thereof are not repeated herein.

The operation of the winding mechanism 22 will be briefly described.

When a user pulls one end of the auxiliary rope 23 outwards to drive the winding roll 221 and the coil spring to rotate (for example, anticlockwise rotation), the balls in the grooves roll along the direction of the arc-shaped notch, and when the auxiliary rope 23 is led out for a certain distance, the balls move into the ball clamping grooves to form a clamping effect, at the moment, the winding roll 221 stops rotating and the length of the auxiliary rope 23 is fixed for use, if the auxiliary rope 23 needs to be pulled outwards continuously, the auxiliary rope 23 only needs to be pulled, the balls move into the grooves from the ball clamping grooves, and therefore the length adjustment of the auxiliary rope 23 can be achieved by repeating the actions.

On the contrary, when the auxiliary rope 23 is to be wound, as long as the balls are located in the ball catching grooves, the auxiliary rope 23 is pulled and then released, at this time, the balls are separated from the ball catching grooves and return to the grooves, and the winding roll 221 rotates clockwise due to the elastic restoring force of the coil spring, so that the auxiliary rope 23 is retracted to the winding roll 221, and therefore, according to the above actions, the pulling-out, the retracting and the pulling-out length adjustment of the auxiliary rope 23 can be realized, which is very convenient. In this embodiment, the auxiliary rope 23 is a steel wire rope to ensure the structural strength.

The helping hand box 2 that this embodiment provided includes supplementary rope 23, and the one end of supplementary rope 23 is connected in charging cable 3 or rifle 7 that charges for supplementary rope 23 can carry the lifting and pulling to charging cable 3 and rifle 7 that charges on vertical direction, with the pulling force that reduces user pulling charging cable 3 and rifle 7 that charges, makes the charging process more laborsaving.

Optionally, as shown in fig. 3 or fig. 4, the second limiting structure 211 is disposed on an outer wall of the box body 21, and the second limiting structure 211 includes one of the following: a tool block, a tool groove, a T-shaped block and a T-shaped groove. The second limit structure 211 is matched with the first limit structure 12, and for example, when the first limit structure 12 is an i-shaped block, the second limit structure 211 is an i-shaped groove; when the first limit structure 12 is a tool-shaped groove, the second limit structure 211 is a tool-shaped block; when the first limit structure 12 is a T-shaped block, the second limit structure 211 is a T-shaped groove; when the first limit structure 12 is a T-shaped groove, the second limit structure 211 is a T-shaped block;
