Description

滚筒设备
本申请要求于2018年04月28日提交中国专利局、申请号为PCT/CN2018/085109、申请名称为“滚筒设备”的国际申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及机械设备领域，并且更具体地，涉及滚筒设备。
背景技术
为了检验手机等电子产品的可靠性，需要产品出厂前对其进行重复自由跌落试验，例如，GB/T2423.8-1995或IEC60068-2-32等标准规定了用于该试验的滚筒设备的制造标准。
但是，该标准的最近的更新时间为1990年，随着技术的发展进步，试验的对象(例如，手机)已经发生了较大变化，例如，目前主流的手机的结构参数(例如，大小和材质)已经与该标准制定时手机的结构参数有很大不同。
采用基于该标准制造的滚筒设备对当前的主流手机进行的重复自由跌落试验，经过2700次跌落姿态统计，手机的左右面跌落概率总共高达90％以上。
即，基于该标准制造的滚筒已不能满足跌落方向随机的问题，存在左、右方向局部过应力，与用户实际跌落场景不匹配。
因此，亟需提供一种技术，能够提高重复自由跌落试验中，电子设备(例如，手机)的跌落的随机性。
发明内容
本申请提供一种滚筒设备，用于重复自由跌落试验，该滚筒设备包括由两个顶壁和四个侧壁围成隔舱，该滚筒设备能够绕第一轴旋转，该第一轴分别与第一侧壁和第二侧壁连接，该第一侧壁和该第二侧壁彼此相面对，该隔舱被经过该第一轴且平行于该两个顶壁的第一平面划分为轴对称的两个部分，该至少两个部分中的每个部分包括：碰撞部件110，设置在第一顶壁上，或者，该第一顶壁由该碰撞部件110构成；楔形块130，设置在第四侧壁和该第一顶壁的结合部，该楔形块130的硬度小于该碰撞部件110的硬度；斜面120，设置该在第四侧壁上，在第一方向上，位于该楔形块130上方，该第一方向是自该第一顶壁朝向该第一轴的方向；窗口140，设置在第三侧壁上，可开闭；至少一个阻挡部件(150)，在试验对象随该滚筒设备的旋转而移动的路径上位于该试验对象自该斜面(120)跌落的边缘的上游。
根据本申请的滚筒设备100，在滚筒设备100静止时，手机被从窗口140放入滚筒设备100的腔体内位于位置#A(即，重力方向上位于第一轴下方的位置)的部分(以下，以部分#A为例进行说明)，具体地说，手机被放在部分#A的碰撞部件110上。随后，启动试验，滚筒设备100绕第一轴转动，即，部分#A从位置#A向位置#B(即，重力方向上位 于第一轴上方的位置)移动。在该过程中，由于碰撞部件110随滚筒设备100的转动而发生倾斜，因此，手机在部分#A的碰撞部件110的表面上向部分#A的楔形块130侧移动。进而，手机可能经由部分#A的楔形块130的阻挡而落至部分#A的斜面120，或者，手机可能经由部分#A的阻挡部件150而落至部分#A的斜面120。从而，部分#A的阻挡部件150可能改变手机的跌落方向或跌落轨迹。由于阻挡部件150具有弹性，因此，每次跌落中，阻挡部件150对手机的跌落方向或跌落轨迹的改变(例如，改变的方向或改变的程度)可能不同，因此，手机每次跌落过程中与碰撞部件110的接触部位的随机性增大，进而增大了手机在试验过程中的跌落的随机性。
可选地，该阻挡部件150在该第一平面上的投影位于该斜面120在该第一平面上的投影的范围内。
从而，能够避免手机在自部分#A的斜面120跌落至部分#B的碰撞部件110的过程中，在与部分#B的碰撞部件110碰撞之间，先与部分#B的阻挡部件150发生接触，从而，能够避免设置阻挡部件150而对试验造成影响。
可选地，该阻挡部件150的硬度小于该碰撞部件110的硬度。
从而，能够避免手机因与该较硬的阻挡部件150发生碰撞而导致手机出现损坏，从而，对试验结果造成影响。

可选地，该阻挡部件150固定在该第四侧壁上的位于该斜面120和该第一顶壁之间的部分160上。
从而，能够避免手机在试验过程中嵌入阻挡部件150与其他部件之间的缝隙中而影响试验的正常进行，进而提高本申请的实用性和可靠性。
可选地，该阻挡部件150与该楔形块130一体成型。
从而，能够容易地实现阻挡部件150的设置和加工。
可选地，该阻挡部件150固定在该第四侧壁上的位于该斜面120和该第一顶壁之间的部分160上。

图1示出了本申请的滚筒设备100的示意性结构图，如图1所示，该滚筒设备100能够绕轴#A旋转。
该轴#A分别在滚筒设备100的两侧与侧壁#a和侧壁#b连接，且该轴#A与侧壁#a(或者，侧壁#b)所在的平面(记作，平面#A)垂直。该滚筒设备100的侧壁#a和侧壁#b随滚筒设备100的旋转而以轴#A为轴旋转。
并且，在本申请中，滚筒设备100可以设计为：轴#A不突出至滚筒设备100的腔体内。并且，该轴#A与侧壁#c(或者，侧壁#d)所在的平面(记作，平面#C)平行，即，该轴#A不与该平面#C相交。
从而，该滚筒设备100的侧壁#c和侧壁#b可以随滚筒设备100的旋转而在位置#C和位置#D之间切换。
另外，该轴#A与顶壁(或者，底壁)所在的平面(记作，平面#D)平行，即，该轴#A不与该平面#D相交。

其中，该“规定硬度”可以理解为该碰撞部件110的硬度能够满足跌落试验(例如，GB/T2423.8-1995或IEC60068-2-32等标准)的要求，或者说，该碰撞部件110的硬度能够与手机在实际使用过程中可能跌落到的地面的硬度相近似。
或者，该滚筒设备100的顶壁和底壁本身可以由该碰撞部件110形成。
作为示例而非限定，该碰撞部件110可以为钢板。
在本申请中，设平面#B经过轴#A，并且该平面#B与顶壁(或者，底壁)所在的平面平行，则该平面#B可以将滚筒设备100分成两个部分，即部分#A和部分#B，其中，该部分#A和部分#B的结构可以相似。具体地说，假设部分#A保持位置不变，该部分#B绕轴#A旋转180°后，与该部分#A重合。
为了便于理解，不失一般性，以下，以部分#A为例，对滚筒设备100的结构进行详细说明。
如图1或图2所示，部分#A的底部可以为平滑试验面。
并且，该部分#A的底部可以配置有碰撞部件110和背衬(图中未示出)。
该背衬设置在碰撞部件110下方，例如，该背衬可以为例如，10mm～19mm厚的木板。
作为示例而非限定，该碰撞部件110例如可以为：3mm厚的钢板。
其中，“该背衬设置在碰撞部件110下方”可以理解为，手机在从该滚筒设备100的部分#B跌落至部分#A时，与碰撞部件110发生碰撞，并且，手机不会接触该背衬。

作为示例而非限定，该窗口140的窗盖(图中未示出)可以由透明的聚丙烯材料制成。
此外，如图1所示，侧壁#d上形成有斜面120。
如图1或图2所示，在斜面120和碰撞部件110之间设置有楔形块130。
作为示例而非限定，该楔形块130可以由橡胶(例如，无绒橡胶)制成。

即，“该阻挡部件150位于斜面120的边缘#A的上游”可以理解为，当滚筒旋转后，手机首先经过阻挡部件150所在位置，再经过斜面120的边缘#A。
例如，“该阻挡部件150位于斜面120的边缘#A的上游”，可以是指，当阻挡部件150设置在斜面120上。
再例如，“该阻挡部件150位于斜面120的边缘#A的上游”，可以是指，阻挡部件150设置为突出于楔形块130的斜面。

再例如，该阻挡部件150也可以为1个，或者，该阻挡部件150也可以3个或3个以 上。
再例如，阻挡部件150也可以形成为图7所示形状。此情况下，楔形块130(为了便于理解，图7中未示出)可以为多个，从而，阻挡部件150可以夹在两个楔形块130之间。
或者说，与图6所示的阻挡部件150的不同的是，阻挡部件150可以不与楔形块130的斜面贴合，而自该斜面贯穿楔形块130，即，楔形块130可以被阻挡部件150分隔为多个部分。
即，在一种实现方式中，阻挡部件150可以分别与斜面120、底壁(或顶壁)、侧壁#c上位于斜面120和底壁(或顶壁)之间的部分贴合。
并且，阻挡部件150可以例如，通过螺钉等连接机构，固定在斜面120上。
或者，阻挡部件150可以例如，通过螺钉等连接机构，固定在底壁(或顶壁)上。

或者，该阻挡部件150也可以形成为图5所示形状，此情况下，该槽170的长度可以大于该阻挡部件150的面向该楔形块130的斜面的边的长度，从而，该阻挡部件150可以直接插入至槽170中，即，此情况下，该楔形块130的斜面的边上也可以不形成凸起180。
在形态1下，试验过程中，手机在滚筒设备100的移动过程如下：
在滚筒设备100静止时，手机被从窗口140放入滚筒设备100的腔体内位于位置#A的部分(以下，以部分#A为例进行说明)，例如，手机可以被放在部分#A的碰撞部件110上，或者，手机可以被放在部分#A的楔形块130上，或者，手机可以被放在部分#A的阻挡部件150上。
随后，启动试验，如图1所示，滚筒设备100绕轴#A沿逆时针方向转动，即，部分#A从位置#A向位置#B移动。
在该过程中，由于碰撞部件110随滚筒设备100的转动而发生倾斜，因此，手机在部分#A的碰撞部件110的表面上向部分#A的楔形块130侧移动。
当部分#A移动至位置#C附近时，手机经由部分#A的楔形块130而落至部分#A的斜面120，或者，手机经由部分#A的阻挡部件150而落至部分#A的斜面120，从而，部分#A的阻挡部件150可能改变手机的跌落方向或跌落轨迹。由于阻挡部件150具有弹性，因此，每次跌落中，阻挡部件150对手机的跌落方向或跌落轨迹的改变(例如，改变的方向或改变的程度)可能不同，因此，手机每次跌落过程中与碰撞部件110的接触部位的随机性增大，进而增大了手机在试验过程中的跌落的随机性。
随着转动角度继续增大，手机延部分#A的斜面120滑动，进而朝部分#B的碰撞部件110跌落。

应理解，以上图9至图11所示的形态2的阻挡部件150仅为示例性说明，本申请并未限定于此。本领域技术人员可以根据需要对该形态2的阻挡部件150的设计进行适当变更。

再例如，该阻挡部件150也可以固定在侧壁#a或侧壁#b上。
再例如，在本申请中，可以设置多个(例如，2个或2个以上)阻挡部件150。
此情况下，该多个阻挡部件150可以平行配置。
并且，各阻挡部件150的尺寸和形状可以相似，进而，能够提高阻挡部件150的制造效率
并且，该多个阻挡部件150中的任意两个阻挡部件150之间的距离可以大于或等于10cm。从而，能够避免手机在试验过程中嵌入相邻的两个阻挡部件150之间。从而能够避免因设置阻挡部件150而对试验造成不良影响。
在形态2下，试验过程中，手机在滚筒设备100的移动过程如下：
在滚筒设备100静止时，手机被从窗口140放入滚筒设备100的腔体内位于位置#A的部分(以下，以部分#A为例进行说明)，具体地说，手机被放在部分#A的碰撞部件110上，或者，手机可以被放在部分#A的楔形块130上。
随后，启动试验，如图1所示，滚筒设备100绕轴#A沿逆时针方向转动，即，部分#A从位置#A向位置#B移动。
在该过程中，由于碰撞部件110随滚筒设备100的转动而发生倾斜，因此，手机在部分#A的碰撞部件110的表面上向部分#A的楔形块130侧移动。
当部分#A移动至位置#C附近时，手机经由部分#A的楔形块130(或者，部分#A的阻挡部件150)而落至部分#A的斜面120。或者，手机经由部分#A的阻挡部件150而落至部分#A的斜面120，从而，部分#A的阻挡部件150可能改变手机的跌落方向或跌落轨迹。由于阻挡部件150具有弹性，因此，每次跌落中，阻挡部件150对手机的跌落方向或跌落轨迹的改变(例如，改变的方向或改变的程度)可能不同，因此，手机每次跌落过程中与碰撞部件110的接触部位的随机性增大，进而增大了手机在试验过程中的跌落的随机性。
随着转动角度继续增大，手机延部分#A的斜面120滑动，进而朝部分#B的碰撞部件110跌落。
形态3

如图12所示，该阻挡部件150形成为覆盖斜面120。
在本申请中，该阻挡部件150的摩擦系数可以大于斜面120的摩擦系数。例如，该阻挡部件150可以为橡胶制。
例如，该阻挡部件150可以形成为片状或板状，从而，可以通过例如，粘合剂或螺钉等固定部件固定在斜面120上。
或者，也可以在斜面120上喷涂摩擦系数较大的材料，从而形成阻挡部件150。
在形态3下，试验过程中，手机在滚筒设备100的移动过程如下：

随后，启动试验，滚筒设备100绕轴#A沿逆时针方向转动，即，部分#A从位置#A向位置#B移动。
在该过程中，由于碰撞部件110随滚筒设备100的转动而发生倾斜，因此，手机在部分#A的碰撞部件110的表面上向部分#A的楔形块130侧移动。
当部分#A移动至位置#C附近时，手机经由部分#A的楔形块130(或者，部分#A的阻挡部件150)而落至覆盖在部分#A的斜面120上的阻挡部件150。
随着转动角度继续增大，手机延阻挡部件150滑动，进而朝部分#B的碰撞部件110跌落。
由于阻挡部件150的摩擦系数大于斜面120的摩擦系数，因此，滑动过程中手机收到的摩擦力较大，因此，手机每次跌落过程中与碰撞部件110的接触部位的随机性增大，进而增大了手机在试验过程中的跌落的随机性。
