【经验】智能眼镜无线充电的设计方法：利用瑞萨P9222-R无线电源接收器和P9235A-RB无线电源发送器

时间： 2022-03-26 来源：Renesas

技术问答

近年来，虚拟现实（Virtual Reality）技术和增强现实（Augmented Reality）技术发展迅猛，预计到 2030 年市场将以每年 40% 以上的速度增长。目前，智能眼镜种类有音频眼镜、社交眼镜、AR 眼镜、和 XR 眼镜。由于当前技术水平的限制，智能眼镜的效果不能尽如人意。瑞萨的目标是研发能使智能眼镜能够演变成日常产品的技术。

为了实现该目标，瑞萨（RENESAS）的无线充电团队开发了一套可以为音频眼镜进行无线充电的设计。该设计可作为未来智能眼镜的标准。之所以要在智能眼镜中采用无线充电的设计，是因为这样可以让智能眼镜没有任何充电端口或者引脚，以确保产品不会因此受到灰尘和水的损坏。同时，为了将智能眼镜的使用群体扩展到普通人群，智能眼镜首先要变得适合大众的生活方式。无线充电的设计正是朝着正确方向迈出的第一步。

下面将简单介绍该设计的原型工艺。首先，将P9222-R 无线电源接收器安装在电池和现有芯片所在的智能眼镜框架的一侧。接收器的连接在框架上进行了适当的布线，以便将其连接到被打磨到鼻垫中的接收器线圈。之后，我们修改了一个原型支架，该支架可以很轻易地放置在床头柜上进行充电。此外，Tx线圈连接到鼻桥上的P9235A-RB 无线电源发送器，当将鼻垫放在支架上时，鼻垫将位于该位置。我们使用3D打印机为机头支架创建了一个空心平台，该平台隐藏了Tx芯片，如下所示。

在原型工艺中，我们遇到了一些障碍。这就给未来的原型设计方法留下了一些细微的差别。由于大多数无线产品采用了表面积大的扁平线圈，因此它们在接触定位方面非常方便。然而，在我们的原型的Rx和Tx中，棒形线圈的小尺寸要求线圈之间精确对齐。对于未来的模型而言，它们最好包括磁性定位，以确保接触点对齐。这一概念的未来产品路径包括一个便携式充电箱和一个3D打印支架，用于隐藏线圈内部。
