Referring to fig. 1, fig. 2 and fig. 3, a telescopic wireless charging apparatus is disclosed in a first embodiment of the present utility model, which includes a housing 1, a reel 2, a connecting wire 3, a wireless charging module 4 and a locking assembly 5, wherein the connecting wire 3 is wound on the reel 2, the wireless charging module 4 is positioned on a side surface of the reel 2, the reel 2 is accommodated in the housing 1, and the locking assembly 5 is connected with the housing 1.

The reel 2 has elastic rotation force, and the reel 2 automatically winds the connecting wire 3 based on the elastic rotation force so as to control the length of the connecting wire 3 extending outside the shell 1, achieve the effect of controlling the use length of the connecting wire 3, and store the redundant length in the shell 1.

With continued reference to fig. 2, the housing 1 is provided with an upper cover 15 and a lower cover 16 respectively corresponding to two sides of the reel 2, the upper cover 15 and the lower cover 16 are respectively connected with the housing 1 in a snap-fit manner, and a user can detach the upper cover 15 or the lower cover 16 from the housing 1 to view, replace or repair the internal components.

The center of the lower cover 16 is provided with a fixed column 161, the fixed column 161 penetrates through the reel 2 to be connected with the upper cover 15, and the reel 2 rotates by taking the fixed column 161 as a rotation shaft.

A coil spring 102 is provided in the reel 2, one end of the coil spring 102 is positioned on the reel 2, and the other end of the coil spring 102 is positioned on the fixing post 161, that is, the reel 2 has an elastic turning force based on the connection of the coil spring 102.

Referring to fig. 2, 3 and 4, the locking assembly 5 includes a sliding member 51 and a locking member 52, the sliding member 51 is slidably connected with the housing 1, and one side of the sliding member 51 is exposed to the housing 1, so that a user can drive the sliding member 51 to move linearly relative to the housing 1. The locking element 52 is connected to the housing 1 in an elastically pivotable manner, i.e. the locking element 52 has an elastic pivoting force. One end of the locking member 52 is engaged with the slider 51, and the other end of the locking member 52 is provided with an extended locking arm 521, and the locking arm 521 is in contact with the reel 2. Correspondingly, a plurality of bevel gears 21 are disposed at positions of the reel 2 corresponding to the locking arms 521, the inclination directions of the bevel gears 21 are opposite to the rotation direction of the connecting wire 3 extending outwards from the reel 2, and each bevel gear 21 can abut against the locking arm 521 to lock the rotation of the reel 2.

It will be appreciated that when the spool 2 receives an external force to output the connecting wire 3, the length of the connecting wire 3 outside the housing 1 is gradually increased, the rotation direction of the spool 2 is the direction a (as shown in fig. 4), when the external force is eliminated, the spool 2 has a tendency to rotate in the opposite direction based on the elastic rotation force of the spool 2, and the locking arm 521 abuts against the back of the helical tooth 21, so that the resistive spool 2 rotates to fix the extending length of the connecting wire 3. Since the bevel gear 21 is inclined in the opposite direction, when the user continues to pull the connecting wire 3 to extend outwards, the inclined bevel gear 21 cannot support the locking arm 521 in the direction, so that the user can continue to pull to any position and stop, and the connecting wire 3 can be fixed at the current length.

Optionally, referring to fig. 5 and 6, in some other embodiments, the locking member 52 is provided with a wire arranging plate 522 adjacent to the locking arm 521, the wire arranging plate 522 is disposed corresponding to a position on the reel 2 where the connecting wire 3 is wound, and the wire arranging plate 522 is provided with a rounded structure on a side close to the reel 2.
