Clamping mechanism for wireless charger

Abstract

The invention provides a clamping mechanism for a wireless charger. The clamping mechanism comprises a first sliding block and a second sliding block used for clamping wireless charging equipment, and a support plate arranged at the lower ends of the first sliding block and the second sliding block and used for supporting the wireless charging equipment, wherein the first sliding block is connected with the second sliding block via an elastic element, a limit plate is arranged at a vertical position of each of the first and second sliding blocks, and a pivot joint shaft pivoted with the support plate is arranged under each limit plate; racks are arranged at oppositely arranged transverse parts of the first and second sliding blocks, and a gear engaged with the racks is arranged between the racks of the first and second sliding blocks; strip-shaped through holes matched with the pivot joint shafts and forming certain angles with a horizontal direction are formed in two ends of the support plate. According to the clamping mechanism provided by the invention, a charging coil of the wireless charging equipment can be automatically aligned with the charging coil of the wireless charger, charging efficiency of the wireless charger is ensured, and the characteristic of good university is provided.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a clamping mechanism of a wireless charger. Background technique [0002] The wireless charger is a magnetic induction wireless charger based on the principle of electromagnetic induction for power transmission. The charging principle is: the charging coil of the wireless charger and the charging coil of the wireless charging device form an electromagnetic coupler, and the alternating current carried by the charging coil of the wireless charger generates a magnetic field, which is then generated by the charging coil of the wireless charging device through electromagnetic induction. The voltage used for charging enables wireless charging. It can be seen from its charging principle that the relative position of the charging coil of the wireless charger and the charging coil of the wireless charging device is one of the key factors affecting its charging efficiency.

Problems solved by technology

It can be seen from its charging principle that the relative position of the charging coil of the wireless charger and the charging coil of the wireless charging device is one of the key factors affecting its charging efficiency. Only when the positions of the charging coils of the device are relative to each other can charging with higher efficiency be carried out. When the positions of the charging coils of the wireless charger and the charging coils of the wireless charging device are misaligned, the charging status of the wireless charger will be incorrect. Stable, low charging efficiency

[0003] In the prior art, the charging coil of the wireless charger is aligned with the charging coil of the wireless charging device in two ways: one: detecting the position of the charging coil of the wireless charging device, and driving the wireless charging coil through a motor The charging coil of the charger is aligned with the charging coil of the wireless charging device; second: through the wireless charging box, the wireless charging device is fixed, so that the charging coil of the wireless charger is aligned with the charging coil of the wireless charging device ; The manufacturing cost of the wireless charger adopting the first method is high, and it is difficult to realize; while the charging box of the wireless charger adopting the second method is generally a semi-closed wireless charging box, which cannot be compatible with different sizes (length or Width) wireless charging equipment, when the smaller (shorter length) wireless charging equipment is placed in the wireless charging box for charging, it is easy to be placed in the corner of the wireless charging box, and it is impossible to make the charging coil of the wireless charger Align the charging coil of the wireless charging device; if the size of the wireless charging case is adapted to the smaller wireless charging device, larger (longer) mobile phones will not be able to insert into the wireless charging case Wireless charging within; has the disadvantage of poor versatility
