Description

Technical Field

[0001] The utility model relates to the field of wireless charging smart home, and in particular to a magnetic wireless charging seat and a table. Background Art

[0002] As an important branch of wireless charging technology, magnetic wireless charging is gradually changing our charging habits with its unique fixing method and many advantages. It has won wide recognition in the market due to its convenient placement, precise coil positioning and high charging efficiency. With the continuous development of wireless charging technology, the Wireless Power Consortium has also made significant progress in the standardization of wireless charging protocols, which provides a solid foundation for the widespread application of magnetic wireless charging.

[0003] However, as magnetic wireless charging technology becomes more and more mature, we are also facing some technical challenges that need to be solved urgently. Among them, the problem of magnetic force control is a typical example. At present, most magnetic wireless charging devices use permanent magnets as magnetic elements. Although this type of permanent magnet has strong magnetism, its magnetic force is often difficult to accurately control. In practical applications, this problem of magnetic force control brings many inconveniences. On the one hand, in order to ensure the stability of magnetic attraction, we need to increase the magnetism so that the device can fit tightly during charging to avoid a decrease in charging efficiency or interruption of charging due to shaking. But in this way, when the user needs to remove the device, he needs to use more force, and even needs to use both hands to remove the device, which is not only inconvenient to operate, but may also cause certain damage to the device.

[0004] On the other hand, if we reduce the magnetic force for the convenience of removal, although we can reduce the force required to remove the device, it is difficult to ensure the stability of the device during charging. When the wireless charger is combined with home furnishings (such as a table or sofa), it is also difficult to find the exact charging position, which reduces the ease of use. Therefore, solving the problem of magnetic force control in the field of magnetic wireless charging has become an important issue that technicians in this field must face. Utility Model Content

The housing 1 includes an upper housing 11 and a lower housing 12 nested up and down, and the upper housing 11 can be slidably arranged in the lower housing 12 up and down. In the present embodiment, the upper housing 11 and the lower housing 12 are circular housings with a U-shaped cross section. The lower housing 12 is provided with a guide rail 13 for limiting the lateral displacement of the upper housing 11, and the upper housing 11 slides up and down between the guide rail 13 and the side wall of the lower housing 12. In order to prevent the upper housing 11 from dislodging due to excessive displacement, the present embodiment provides a first protrusion 14 on the outer side of the side wall of the upper housing 11, and a second protrusion 15 on the inner side of the side wall of the lower housing 12. The first protrusion 14 and the second protrusion 15 are used together to limit the maximum displacement of the upper housing 11.

[0028] In order to improve the convenience of taking the charging device, the first electromagnet 4 for attracting the charging device is provided on the upper shell 11 in this embodiment, and the power connection contacts 5 for controlling the wireless charging coil and the first electromagnet 4 to be energized are respectively provided on the lower shell 12 and the upper shell 11, and the power connection contacts 5 are closed when the upper shell 11 drops to the bottom. By setting the power connection contacts 5 to separate as the upper shell 11 is lifted, the magnetic force disappears when the charging device is taken, which greatly improves the convenience of the user to take the device, and also avoids the need to use too much force when taking the device, or even the embarrassment of operating with both hands. For those users who need to frequently take and put back the charging device, it will undoubtedly greatly improve their user experience.

[0029] A touch patch 6 for sensing the presence of a charging device is disposed at the top of the upper shell 11 and is electrically connected to the control mainboard 3. A second electromagnet 7 is disposed in the lower shell 12, and an attracting magnet ring is disposed at a corresponding position in the upper shell 11. When the device leaves the touch patch 6, the second electromagnet 7 is energized, so that the upper shell 11 can automatically retract when not charging.
