Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging stand technology, and in particular to an earphone charging stand. Background Technology
[0002] Existing headphone charging methods generally use PIN pin contact charging or wireless charging. The induction coil of wireless charging is mainly fixed in the middle of the earpiece surface. Some PIN pin charging methods also design the PIN pins on the earpiece surface. Both of these charging methods require the earpiece surface of the headphones to be placed on the charging pad, so a charging stand is needed to support the headphone.
[0003] Existing headphone charging stands are not foldable, resulting in excessive space occupied by the stands when the headphones are not charging. They also take up a lot of space during transportation, thus reducing their practicality and causing some adverse effects on users. To address the shortcomings of existing technologies, we propose a new headphone charging stand. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Example 1, as Figures 1-4 As shown, an earphone charging stand includes a storage rack 1, a base 3 fixedly mounted on the lower end of the storage rack 1, a support frame 2 movably connected inside the storage rack 1, two sets of second sliding grooves 16 inside the support frame 2, a movable rod 4 movably connected to the outer wall of the support frame 2, a second connecting rod 19 movably connected between the storage rack 1 and the support frame 2, and fourth anti-detachment caps 17 welded to both ends of the second connecting rod 19, a first sliding groove 10 inside the storage rack 1, and limit grooves 5 at both ends of the first sliding groove 10, and a base 3 containing... A wireless charging transmitting coil 11 is movably connected to a sliding rod 7 between a movable rod 4 and a second sliding groove 16. A second anti-detachment cap 8 is welded to both ends of the sliding rod 7. A first limiting cap 13 is provided between the movable rod 4 and the limiting groove 5. A first anti-detachment cap 6 is provided on one side of the first limiting cap 13. A spring 15 is sleeved on the outer wall of the first connecting rod 12. A second limiting cap 18 is provided on one side of the spring 15. A first connecting rod 12 is welded between the two sets of first anti-detachment caps 6. A third anti-detachment cap 14 is provided between the first connecting rod 12 and the movable rod 4.
[0022] With the support frame 2 and storage rack 1, the support frame 2 can be folded and stored in the storage rack 1, thereby reducing the storage space occupied by the support when not in use and increasing the practicality of the device.
[0023] Example 2, as Figure 1 As shown, an earphone charging stand has a hanging groove 9 inside the support frame 2.
[0024] The device uses a suspension groove 9 and a support frame 2 to suspend the headphones in the suspension groove 9 even when they are not being charged, preventing the wireless charging receiver coil on the headphones from coming into contact with the wireless charging transmitter coil 11.
[0025] It should be noted that this utility model is an earphone charging stand. In use, the user pulls the support frame 2 upwards, causing the first connecting rod 12 to slide within the first sliding groove 10. When the first connecting rod 12 is within the first sliding groove 10, the first limiting cap 13 is abutted against the outer wall of the storage frame 1 by the first sliding groove 10, and the spring 15 is compressed. When the first connecting rod 12 is between the two sets of limiting grooves 5, because the cross-section of the first limiting cap 13 is smaller than the cross-section of the limiting groove 5, under the rebound action of the spring 15, the first limiting cap 13 is pushed into the limiting groove 5. When the first limiting cap 13 is inside the first set of limiting grooves 5, the other end of the movable rod 4 is located at the lowest end of the second sliding groove 16, and the support frame 2 is retracted into the storage frame. When the first limiting cap 13 is in the second limiting groove 5 inside the holder 1, the other end of the movable rod 4 is located at the uppermost end of the second sliding groove 16, thereby supporting the support frame 2. The headband of the headphones can be inserted into the square hole inside the support frame 2. The wireless charging receiving coil on the headphones is in contact with the wireless charging transmitting coil 11 to charge the headphones. When charging is not required, the headphones can be put on the hanging groove 9 so that the ear pads of the headphones are away from the wireless charging transmitting coil 11, and charging is stopped. When the support frame 2 needs to be retracted, the first limiting cap 13 is simply snapped outward and the spring 15 is manually compressed so that the first limiting cap 13 is dislodged from the limiting groove 5. The first connecting rod 12 can then be moved to change the position of the limiting groove 5.
