本发明属于无线充电技术领域，特别涉及一种强吸力磁吸无线充电设备及磁吸无线充电控制方法。The invention belongs to the technical field of wireless charging, and in particular relates to a strong suction magnetic suction wireless charging device and a magnetic suction wireless charging control method.
背景技术Background technique
车载无线充的手机固定有两种方法，磁吸式固定和夹子式固定。前者依靠磁铁吸力实现手机固定，后者依靠夹子夹住手机，保证手机不掉落。前者优点是，方便，即放既吸，线圈对位准，充电效率高；缺点是吸力小；后者优点是夹的紧，但是会导致手机和无线充电有间隙，导致充电效率低。There are two ways to fix the mobile phone of the car wireless charger, magnetic fixation and clip fixation. The former relies on magnet suction to fix the mobile phone, while the latter relies on clips to hold the mobile phone to ensure that the mobile phone does not fall. The advantage of the former is that it is convenient, that is, it can be released and sucked, the coil is aligned, and the charging efficiency is high.
现有磁吸无线充产品，都是使用钕铁硼材料的磁铁。无线充能量发射器的线圈外围有一圈磁铁。手机内部的线圈外围也有一圈磁铁。磁铁的N极和S极通过磁力使无线充能量发射器和手机吸在一起。无线充能量发射器和手机内部磁铁的排布，如图1所示，由38块小磁铁构成磁环，手机内和无线充能量发射器均是相同的磁环，仅磁铁极性不同。磁铁极性如图2所示，无线充能量发射器的磁铁01上表面的N极和手机内部的磁铁02的S极相吸，无线充能量发射器的磁铁01上表面的S极和手机内部磁铁02的N极相吸，实现无线充能量发射器和手机相吸。The existing magnetic suction wireless charging products are all magnets using NdFeB materials. There is a circle of magnets around the coil of the wireless charging energy transmitter. There is also a ring of magnets around the coil inside the phone. The N pole and S pole of the magnet make the wireless charging energy transmitter and the mobile phone attract together by magnetic force. The arrangement of the wireless charging energy transmitter and the internal magnets of the mobile phone, as shown in Figure 1, consists of 38 small magnets to form a magnetic ring. Both the mobile phone and the wireless charging energy transmitter are the same magnetic ring, only the polarity of the magnets is different. The polarity of the magnet is shown in Figure 2. The N pole on the upper surface of the
然而，无线充能量发射器的吸力通常不强，汽车颠簸时会导致手机等待充电装置跌落。该磁铁为充磁磁铁，其自身吸力由材料、尺寸决定，受到手机尺寸限制和量产的材料限制，吸力无法进一步提升。However, the suction power of the wireless charging transmitter is usually not strong, and the bumping of the car can cause the phone to fall while waiting for the charging unit. The magnet is a magnetized magnet, and its suction force is determined by the material and size. Due to the limitation of the size of the mobile phone and the material limitation of mass production, the suction force cannot be further improved.
因此，如何提高磁吸无线充电设备的磁吸力，是本领域技术人员亟待解决的问题。Therefore, how to improve the magnetic attraction force of the magnetic attraction wireless charging device is an urgent problem to be solved by those skilled in the art.
