Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

The utility model relates to a wireless elevating gear that charges of desktop refers to attached figure 1-3, including table 1, be equipped with recess 12 on the table 1, the bottom of recess 12 is equipped with foil gage 31, foil gage 31 coupling spring 33's one end, and spring 33's the other end is the free flexible end, and the wireless charging panel is connected to the free flexible end, and the back of wireless charging panel is equipped with first magnetism and inhales the piece, in recess 12 with the piece is inhaled to first magnetism second magnetism that corresponds and inhale the piece. In this embodiment, the first magnetic attraction piece and the second magnetic attraction piece are both electromagnets. The first electromagnet 22 is electrified to the circuit 24, and the second electromagnet 31 is electrified to the circuit 321. The lateral wall of recess 12 transversely is equipped with spacing hole 13, and the corresponding spacing hole 13 direction of wireless charging panel is equipped with the spacer pin of activity, and the spacer pin includes movable block 231 and the little spring 232 of being connected with the movable block in this embodiment.

Referring to fig. 1, when the first electromagnet 22 and the second electromagnet 31 are powered on and attracted, the spring 33 is compressed, the wireless charging pad moves downward, and the movable limit pin on the wireless charging pad presses the side wall of the groove 12 and moves downward along with the wireless charging pad. Referring to fig. 2, when the stopper pin moves into the stopper hole 13 and springs open to be caught in the stopper hole 13. At the moment, the wireless charging plate is used for being connected with the heat preservation cover and charging the heat preservation cover.

Referring to fig. 3, when the first electromagnet 22 and the second electromagnet 31 are disconnected due to power loss, the spring 33 releases elastic force, the wireless charging plate moves upwards, the movable limiting pin is pulled out of the limiting hole 13 by the upward pulling force of the spring 33, the wireless charging plate moves towards the desktop, after the wireless charging plate moves for a certain time, the second electromagnet 31 located at the bottom of the groove is electrified, and the wireless charging plate is subjected to a magnetic force F which is downward smaller than the gravity of the wireless charging plate, so that the wireless charging plate slowly moves to be flush with the desktop and stops moving. The wireless charging panel is provided with a QI protocol (also referred to as a wireless charging standard), and can be used for charging electronic equipment such as a mobile phone or a tablet.

In order to avoid the position limit of the limit pin, the opening end of the limit hole 13 is set to be an arc-shaped guide surface 131. When the wireless charging panel moves upward, the limit pin gradually slides out of the limit hole 13 along the arc-shaped guide surface 131; when the wireless charging pad moves downward, the stopper pin 231 gradually slides into the stopper hole 13 along the arc-shaped guide surface 131. As a more preferable embodiment, a surface of the moving block 231 of the stopper pin contacting the arc-shaped guide surface is also provided as the arc-shaped surface 2311, so that the stopper pin can be prevented from being stuck during the movement. Of course the contact surfaces may be provided with other shapes, such as chamfers.

The radius of curvature of the arc guide surface 131 may be set between 5 mm and 15 mm for smooth movement of the wireless charging pad. Such as 5 mm, 10 mm and 15 mm. When the curvature radius is too large, the limiting pin can fast draw out the limiting hole 13, and when the curvature radius is too small, the movable limiting pin moves across the surface, so that clamping stagnation is easy to occur.

As a further preferred embodiment, a limiting rib 11 is provided at the edge of the groove 12, and when the spring 33 releases the elastic force, in order to avoid the too large elastic force causing the jumping of the wireless charging pad during the movement, the limiting rib 11 is provided to play a role of buffering and limiting, and secondly, to play a role of sealing, so as to prevent dirt or water from entering the groove 12. As a preferred embodiment, the limiting rib 11 may be made of rubber. The rubber has good elasticity, strong buffering capacity, water resistance and good sealing effect.

A wireless charging table is provided, which is a desktop wireless charging lifting device. The desktop wireless charging lifting device is arranged on the desk plate 1 in pairs. In order to guarantee that the heat preservation cover can be stably placed, the wireless charging lifting device is better. As a preferred embodiment, the desktop wireless charging lifting devices are also provided with a plurality of pairs, and are uniformly distributed on the desk board 1. But the heat preservation cover heating is more even to no matter the position of sitting at the desk can both charge electronic equipment such as cell-phone, it is more convenient to charge.

The utility model provides a wireless elevating gear that charges of desktop, inhale the actuation of piece and the break-make realization spring 33 of inhaling and the pull-up and the compression of piece through the first magnetism of wireless charging panel below and second magnetism in 1 recess 12 of table, realize wireless charging panel arrange recess 12 in when the cover that keeps warm charges in, wireless charging panel is automatic flushes with table 1 when not, and convenient to use does not account for the place.

It is obvious that the above described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
