车门控制器拆解学习记录
本帖最后由 poponianhua 于 2025-1-13 21:25 编辑<h1 id="h1--markdown-"><span style="font-size:16px;">本次拆解评测的样本为EEWorld拆解活动第18期（<a href="https://bbs.eeworld.com.cn/thread-1302050-1-1.html" target="_blank">https://bbs.eeworld.com.cn/thread-1302050-1-1.html</a>）四号拆品——车门控制器。</span></h1>
<p>看到评测产品被剪断的导线时，觉得这个产品有点low，可是当拆开外壳，又有了很惊艳的感觉。</p>
<p> </p>
<p>首先看产品图。有点旧，看起来很普通。</p>
<div style="text-align: center;"></div>
<p> </p>
<p>这两组导线的卡扣设计很好，既省力又很牢固，适合在运动的场景下来使用。</p>
<p> </p>

<p>内部电路板图。</p>
<div style="text-align: center;"></div>
<p> </p>
<p>本以为车门控制器的电路会很简单，没有想到拆开后会看到这么多的元件和这么复杂的电路走线。并且重要的元器件上被涂抹了，看不清具体的型号。需要花较多的时间和精力来学习这个板子。</p>
<p> </p>

这个电路板应该很久了。芯片的资料很多都搜索不到。真是不好找。 <p class="p" style="text-align:left; text-indent:0pt; padding:0pt"><span style="font-size:medium"><span style="font-family:Calibri"><span style="color:#000000"><span style="font-style:normal"><span style="font-weight:400"><span style="white-space:normal"><span style="text-decoration:none"><span style="line-height:28pt"><b><span style="font-size:14pt"><span style="font-family:"Microsoft yahei""><span style="color:#4f4f4f"><span style="letter-spacing:0pt"><span style="font-weight:bold"><span style="font-style:normal"><font face="Microsoft yahei">经过大费周折的辨认和查询，现将识别出来的芯片如下。</font></span></span></span></span></span></span></b></span></span></span></span></span></span></span></span></p>
