用了十几年的圆珠笔,你知道它的工作原理吗?

How Does a Clicky Pen Work?

You’ve probably used a clicky pen very recently.
你最近可能用到过圆珠笔
Even if you’ve taken one apart, it’s still hard to understand how it works.
可即使拆开它 你依然很难理解它的工作原理
Lucky for us, we’ve got 3D animation on our side.
幸运的是 我们可以用3D动画来展示它的原理
The clicky pen consists of several different parts.
圆珠笔由几个不同的部分构成:
The lower barrel,
下笔管
the spring,
弹簧
the ink cartridge,
笔芯
the clip,
笔盖
the upper barrel,
上笔管
the push button,
按钮
and the cam.
凸轮
Push and release, and the pen tip is out.
按下再松开 笔尖就出来了
Push and release again, and the tip is in.
再次按下松开 笔尖缩回
Take a look at what happens when the ink cartridge is pressed downward.
看看按下按钮时笔芯的运动
The spring gets compressed
弹簧被压缩
and provides resistance against the button press.
反向推动按钮
Most of the action happens up here.
大部分的动作都发生在这里
Let’s get a closer look.
让我们仔细看看
The push button has eight notches on the side that guide it as it slides in and out.
按钮外周有八个凸起 可以在滑入滑出时啮合
Notice the jagged edges at the very end.
注意最末端的锯齿状边缘
The cam has only four teeth at the end but they’re pointed the other way.
凸轮末端只有四个齿 但它们指向另一端
This piece translates linear motion into rotational motion.
这个部件将直线运动转化为旋转运动
In fact, it’s the only piece that’s allowed to rotate.
实际上 这是唯一一个可以旋转的部件
The guides are molded into the upper barrel.
上笔管内置导轨
The notches in the push button slide up and down these guides.
按钮上的凸起沿着导轨上下滑动
The four white teeth on the cam slide up and down these edges.
凸轮上四个白色的齿沿着边缘上下滑动
Alright let’s put all these pieces together.
好了 让我们把这些部件放在一起
Starting with the pen tip in.
从笔尖开始
You’ll notice that the cam teeth are halfway along these edges.
你会注意到凸轮齿位于这些边缘的中间位置
If the guides weren’t there, the spring resistance would cause the teeth to slide all the way in.
如果没有导轨 弹簧的推力会把凸轮齿推到底部
Instead we’re kind of at an awkward halfway point.
但现在 凸轮齿处于中间位置
The button is pushed and the cam begins to slide.
按下按钮 凸轮滑动
Once the cam teeth are free of the guides,
凸轮齿脱离导轨后
the cam rotates just a bit while they slide into the edges.
凸轮只需旋转一点 凸轮齿就会滑入边缘
The contact is what creates the first click.
这里接触时 发出第一次咔哒声
As the button is released, the cam teeth come in contact with the guide edges causing more rotation.
按钮被松开后 凸轮齿与导轨边缘接触导致更大的旋转
As soon as the teeth are free of the push button edges it slides all the way in again.
凸轮齿脱离按钮边缘后 它将再次滑动
This is the second click.
就发出了第二次咔哒声
The cam doesn’t go back as far which is why the pen tip stays out.
因为凸轮没回到原来位置 笔尖留在外边
To get the pen tip back in, we repeat this same process.
想让笔尖收回 需要重复相同的过程
Push and release has two clicks
按下和释放会发出两次咔哒声
but if it happens fast enough, it may sound like one click.
但如果速度足够快 听起来就像一声
Now keep in mind that this is just one kind of pen mechanism,
请注意 本视频只介绍了一种笔的装置结构
not all clicky pens will work like this but they’re probably similar.
并非所有圆珠笔都是这样 但原理是相似的

如果你是新观众
