[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] This utility model embodiment provides a telescopic wireless charging module, such as Figures 1 to 8 As shown, the telescopic wireless charging module includes a mounting base 1 and a wireless charging body 2; the mounting base 1 is provided with a mounting position 11 having an extension opening 111, and the wireless charging body 2 can be slidably mounted on the mounting position 11 so that the wireless charging body 2 can extend or retract on the mounting base 1 through the extension opening 111; the mounting base 1 is provided with a locking component 3 and a sliding inner frame 4, and the locking component 3 includes an elastic locking element 31; the wireless charging body 2 is connected to the sliding inner frame 4.

[0034] In the locked state, the wireless charging body 2 is housed in the mounting position 11, and the elastic locking member 31 extends into the mounting position 11 and locks the wireless charging body 2. In the locked state, pushing one end of the wireless charging body 2 from the protrusion 111 side causes the wireless charging body 2 to retract in the mounting position 11 and drive the sliding inner frame 4 to move in the same direction. The sliding inner frame 4 drives and holds the elastic locking member 31 to retract, thereby unlocking the wireless charging body 2, and the sliding inner frame 4 is positioned at the current position. When the wireless charging body 2 is forced to extend outward from the mounting position 11 to the maximum extension extent, the wireless charging body 2 drives the sliding inner frame 4 to move in the same direction. The sliding inner frame 4 releases the drive and holding of the elastic locking member 31 to retract, and the elastic locking member 31 extends into the mounting position 11 to reset, and the sliding inner frame 4 is positioned at the current position.

[0035] The retractable wireless charging module of this utility model has a mounting position 11 with an extension opening 111 on the mounting base 1. The wireless charging body 2 can be slidably mounted on the mounting position 11, and the elastic locking member 31 locks or unlocks the wireless charging body 2. Specifically, in use, in the locked state ( Figure 5 Pushing one end of the wireless charging body 2 from the protrusion 111 side causes the wireless charging body 2 to retract in the mounting position 11, simultaneously moving the sliding inner frame 4 in the same direction. The sliding inner frame 4 drives and holds the elastic locking piece 31 inward, thereby unlocking the wireless charging body 2. Figure 6 The sliding inner frame 4 remains in its current position. When the wireless charging body 2 extends outward to its maximum extent towards the mounting position 11 under pressure, the wireless charging body 2 drives the sliding inner frame 4 to move in the same direction. The sliding inner frame 4 releases the inward drive and retention of the elastic locking member 31, and the elastic locking member 31 extends back into the mounting position 11 to reset, positioning the sliding inner frame 4 in its current position. When not in use, simply push the wireless charging body 2 back into the mounting position 11, and the elastic locking member 31 will relock the wireless charging body 2. The unlocking and locking process of the wireless charging body 2 of the telescopic wireless charging module can be completed with simple pressing and pushing, making unlocking and locking convenient and providing a good user experience.

[0036] The retractable wireless charging module of this utility model is installed in a wireless charger via the mounting base 1. When in use, the wireless charging body 2 extends from the wireless charger; when not in use, it retracts back into the wireless charger. A wireless charging coil, preferably a magnetic charging coil, is installed inside the wireless charging body 2. A wireless charging position 25 is provided on the wireless charging body 2 corresponding to the wireless charging coil.

[0037] Specifically, the wireless charging body 2 has a locking groove 21 at its bottom; the locking component 3 also includes an elastic element 32, which is installed in the mounting base 1 and connected to the elastic locking element 31 to drive the elastic locking element 31 to extend to the mounting position 11 and engage with the locking groove 21; the elastic locking element 31 has a first inclined surface 311. The sliding inner frame 4 has an accommodating opening 41, in which the elastic locking element 31 is located. A driving boss 42 is provided on the side of the accommodating opening 41 near the protrusion 111, and a second inclined surface 421 adapted to the first inclined surface 311 is provided on the driving boss 42 to drive the elastic locking element 31 to retract. Specifically, the elastic element 32 is a spring.

[0038] In the locked state, driven by the elastic force of the elastic element 32, the elastic locking element 31 is inserted into the locking groove 21 to lock the wireless charging body 2. When the wireless charging body 2 is pushed inward, it drives the sliding inner frame 4 to move in the same direction, and the second inclined surface 421 presses against the first inclined surface 311, thereby pressing the elastic locking element 31 back into the mounting base 1 through the second inclined surface 421, thus unlocking the wireless charging body 2. And because the second inclined surface 421 maintains pressure against the first inclined surface 311 in the current state, the elastic locking element 31 cannot extend and reset again, and the elastic locking element 31 will not obstruct the wireless charging body 2 when it is extended outward for use. Specifically, the elastic element 32 is a spring 10. The accommodating opening 41 can avoid the mounting boss 12 and provide the driving boss 42. A third inclined surface 23 is provided on the side of the locking groove 21 away from the protrusion 111, so that the elastic locking element 31 can be inserted into the locking groove 21 when the wireless charging body 2 is stored.

[0039] Furthermore, a mounting boss 12 is provided on the opposite side of the mounting position 11 inside the mounting base 1. The mounting boss 12 has a mounting cavity 121 and is located in the receiving opening 41. The elastic locking member 31 is installed in the mounting cavity 121. The mounting cavity 121 has locking grooves 122 on both sides, and the elastic locking member 31 has locking ribs 312 on both sides, which are locked in the locking grooves 122. The mounting cavity 121 facilitates the installation and positioning of the elastic locking member 31. Through the cooperation between the locking grooves 122 and the locking ribs 312 on both sides of the elastic locking member 31, the rotation of the locking member is restricted, and lateral displacement caused by the sliding inner frame 4 driving the boss 42 to apply lateral force is avoided.

[0040] The mounting boss 12 has an opening on the side near the protrusion 111, through which the second inclined surface 421 is inserted to press against the elastic locking member 31. The opening on the side of the mounting boss 12 near the protrusion 111 facilitates the insertion of the second inclined surface 421 into the first inclined surface 311 to push the elastic locking member 31.

[0041] In one embodiment, for the positioning of the sliding inner frame 4, a first magnetic 5 is provided at the end of the mounting base 1 near the protrusion 111, a second magnetic 6 is provided at the end of the sliding inner frame 4 near the protrusion 111, a third magnetic 7 is provided at the end of the sliding inner frame 4 away from the protrusion 111, and a fourth magnetic 8 is provided at the end of the mounting base 1 away from the protrusion 111. When the sliding inner frame 4 is driven and holds the elastic locking member 31 inward, the third magnetic 7 and the fourth magnetic 8 magnetically attract each other to position the sliding inner frame 4 at the current position; when the sliding inner frame 4 releases the drive and holding of the elastic locking member 31 inward, the first magnetic 5 and the second magnetic 6 magnetically attract each other to position the sliding inner frame 4 at the current position. This solution achieves the positioning of the sliding inner frame 4 through the magnetic cooperation of the third magnetic 7 and the fourth magnetic 8, and the magnetic cooperation of the first magnetic 5 and the second magnetic 6, so that the sliding inner frame 4 can be held at the corresponding current position, maintaining the state of the elastic locking member 31 inward or outward. When the wireless charging body 2 extends and retracts, it causes the sliding inner frame 4 to move in the same direction, overcoming the magnetic attraction between the third magnetic member 7 and the fourth magnetic member 8 or the magnetic attraction between the first magnetic member 5 and the second magnetic member 6.

[0042] Furthermore, a sliding groove 112 is provided on the mounting position 11 along the telescopic direction of the wireless charging body 2, and a sliding groove 43 corresponding to the sliding groove 112 is provided on the sliding inner frame 4 along the telescopic direction of the wireless charging body 2; a sliding push post 22 is provided at the bottom of the wireless charging body 2 corresponding to the sliding groove 112, and the sliding push post 22 passes through the sliding groove 112 and is inserted into the sliding groove 43. When the wireless charging body 2 is pushed inward from the extension opening 111 side in the locked state, the sliding push post 22 pushes the end of the sliding groove 43 away from the extension opening 111, so as to drive the sliding inner frame 4 to move in the same direction, and the sliding inner frame 4 drives and keeps the elastic locking member 31 retracting; when the wireless charging body 2 is stretched outward from the mounting position 11 to the maximum extension degree under force, the sliding push post 22 pushes the end of the sliding groove 43 near the extension opening 111, so as to drive the sliding inner frame 4 to move in the same direction, and the sliding inner frame 4 releases the driving and holding of the elastic locking member 31 retracting. This solution uses a sliding push column 22 at the bottom of the wireless charging body 2 to push the two ends of the sliding groove 43, thereby driving the sliding inner frame 4 to move in the same direction. The structure is simple, stable and reliable.

[0043] Specifically, sliding grooves 112 are provided on both sides of the mounting position 11 along the telescopic direction of the wireless charging body 2, and sliding grooves 43 are provided on both sides of the sliding inner frame 4 along the telescopic direction of the wireless charging body 2; sliding push columns 22 are provided on both sides of the bottom of the wireless charging body 2 corresponding to the sliding grooves 112. By providing a set of sliding grooves 43 and sliding push columns 22 on each side of the bottom of the mounting position 11 and the wireless charging body 2, the movement stability of the sliding inner frame 4 is improved.

[0044] Specifically, mounting position 11 is a recessed groove. Mounting protrusions 13 are provided on both sides of the protrusion 111, and a mounting flange 14 is provided on the side of mounting position 11 away from the protrusion 111. The telescopic wireless charging module includes two guide rods 9 and two springs 10. One end of each guide rod 9 is mounted on the mounting flange 14, and the other end is mounted on the two mounting protrusions 13 respectively. Sliding protrusions 24 are provided on both sides of the wireless charging body 2 away from the protrusion 111, and the two sliding protrusions 24 slide through the two guide rods 9 respectively. The two springs 10 are respectively sleeved on the two guide rods 9, with one end abutting against the side of the mounting flange 14, and the other end abutting against the side of the sliding protrusion 24 facing the mounting flange 14. The cooperation of the guide rods 9 and the sliding protrusions 24 ensures the telescopic stability of the wireless charging module. The springs 10 provide elastic force when the wireless charging module extends, realizing the automatic pop-out of the wireless charging module.
