如图1及图2所示，一实施方式的双马达驱动器10主要应用在大型器械中，例如电动床等，以调节目标结构的位置，使得目标结构更加符合用户的需求，常见的目标结构有椅架、床架或机器操作台等等。
在本实施方式中，双马达驱动器10包括驱动器本体及手控器14，驱动器本体包括外壳100、驱动机构200、控制组件300及电连接组件400，驱动机构200、控制组件300及电连接组件400均安装在外壳100上，且驱动机构200通过电连接组件400与控制组件300电性连接，手控器14与控制组件300电性连接，以控制驱动机构200，进而实现对与驱动机构200连接的目标结构的调节。
其中，驱动机构200设有两组，相应地，电连接组件400也设有两组，与两组驱动机构200一一对应设置。因两组驱动机构200的结构相同，下面主要对其中一组驱动机构200进行说明，电连接组件400同理。
具体地，请参考图1及图8，外壳100包括主壳体110及与主壳体110连接的控制盒120，主壳体110内设有容置腔112，两组驱动机构200对称地设置于容置腔112内，控制盒120位于容置腔112外。
在本实施方式中，主壳体110与控制盒120可拆卸连接，以方便组装和检修。
如图3至图7所示，外壳100还包括连接件130，控制盒120包括相对设置的第一表面122及第二表面124，主壳体110具有与第二表面124接触的接触面114，控制盒120上设有第一插孔126，第一插孔126贯穿第一表面122及第二表面124，接触面114上设有与容置腔112连通的第二插孔116，第二插孔116正对于第一插孔126，连接件130穿设于第一插孔126及第二插孔116，以连接主壳体110及控制盒120。
更为具体地，连接件130整体成L型，包括操作部131、延伸部133及锁定部135，延伸部133的一端与操作部131连接，另一端与锁定部135连接，第一表面122位于操作部131与第二表面124之间，延伸部133穿设于第一插孔126及第二插孔116，锁定部135包括多个环绕延伸部133且间隔设置的旋齿137，各旋齿137均能与主壳体110抵接，第二插孔116的形状与锁定部135的形状匹配。
当控制盒120与主壳体110相对固定时，旋齿137与主壳体110的内壁抵接，以勾住主壳体110，此时，连接件130无法在第二表面124至第一表面122的方向上相对于主壳体110和控制盒120运动，也即，此时的连接件130是锁定主壳体110和控制盒120的。连接件130能相对于主壳体110及控制盒120旋转，当连接件130旋转一定的角度，使得旋齿137在第二表面124上的投影落在第二插孔116在第二表面124上的投影范围内时，便能使得连接件130脱离主壳体110，此时，主壳体110便能与控制盒120分离。
对于本实施方式的双马达驱动器10来说，通过连接件130连接主壳体110与控制盒120的方式，不仅较为牢固，还能直接手动分离主壳体110与控制盒120，十分方便。当然，在其他实施方式中，也可以通过其他方式实现主壳体110与控制盒120的可拆卸连接，例如将主壳体110与控制盒120螺纹连接、卡扣连接等。
为了更加方便用户锁定或分离主壳体110与控制盒120，第一表面122上设有用于提示用户的锁定标记102及解锁标记104，连接件130能相对于主壳体110及控制盒120旋转，以从指向锁定标记102的状态切换至指向解锁标记104的状态。当连接件130指向锁定标记102时，连接件130锁定控制盒120与主壳体110，当连接件130指向解锁标记104时，连接件130相对于主壳体110可拆，从而能实现主壳体110与控制盒120的分离。
可以理解的是，在其他实施方式中，锁定标记102与解锁标记104也可以省略，通过设置限位结构来限制连接件130的两个旋转的极限位置，也能便于用户的操作。
为了避免双马达驱动器10在搬运或使用过程中，连接件130因意外触碰而旋转，可以在连接件130指向锁定标记102时，固定住连接件130与控制盒120。
在本实施例中，操作部131上设有第一限位孔106，第一表面122上设有第二限位孔108，操作部131指向锁定标记102时，第一限位孔106正对于第二限位孔108。利用插销插在第一限位孔106和第二限位孔108内，可以限制连接件130相对于控制盒120的旋转。
进一步，连接件130还能相对于控制盒120在平行于第一表面122至第二表面124的方向上移动。
一实施例中，外壳100还包括弹性件160，弹性件160设于控制盒120内，且套设于连接件130上，弹性件160的一端与控制盒120抵接，另一端与连接件130抵接。当连接件130锁定控制盒120和主壳体110时，也即，连接件130指向锁定标记102时，弹性件160被压缩。在该状态下，双马达驱动器10在外力作用下发生抖动或放置方向被改变时，弹性件160能够防止连接件130从锁定标记102慢慢向解锁标记104转动。当连接件130旋转至能与主壳体110分离的位置时，也即，连接件130指向解锁标记104时，弹性件160直接将连接件130弹出第二插孔116。因此，弹性件160的设置对于用户的操作更加省力。可以理解的是，在其他实施例中，弹性件160也可以省略，直接手动将连接件130拔出第二插孔116。
另外，弹性件160还可以限制连接件130相对于控制盒120在第二表面124至第一表面122的方向上移动，以防在控制盒120和主壳体110分离后，连接件130从控制盒120中脱离出来而丢失。
为实现主壳体110与控制盒120的快速组装，如图4及图7所示，主壳体110上设有定位柱140，控制盒120上设有定位孔150，定位柱140插入定位孔150内。在本实施方式中，定位柱140设有多个，间隔设置在主壳体110上，定位孔150与定位柱140一一对应。可以理解的是，在其他实施方式中，定位柱140和定位孔150的数目也可以都为一个。另外，在其他实施方式中，定位柱140与定位孔150的设置位置可以互换，也即，将定位柱140设置在控制盒120上，将定位孔150设置在主壳体110上。
请参考图8及图9，驱动机构200包括马达210、传动杆220及滑块230；目标结构包括摆动件240及转轴250，马达210通过电连接组件400与控制组件300电性连接，并与传动杆220传动连接；滑块230设置在传动杆220上，摆动件240抵接在滑块230上，并与转轴250固定连接；转轴250与主壳体110转动连接，转轴250用于连接目标结构的其余结构。
马达210通过驱动传动杆220旋转以带动滑块230做直线往复运动，滑块230运动的过程中会实现摆动件240的旋转，从而摆动件240带动转轴250旋转，进而转轴250将旋转运动直接或间接地传递至目标结构的其余结构上，以实现目标结构的调节。
主壳体110上设有沿传动杆220的轴向延伸的运动槽111，滑块230滑动设置在运动槽111内。运动槽111主要起到对滑块230的运动进行导向的作用，避免滑块230随传动杆220一起旋转。在其他实施方式中，也可以在主壳体110内设置与滑块230滑动配合的导轨，导轨沿传动杆220的轴向延伸。
值得一提的是，在本实施方式中，滑块230与摆动件240抵接的端面232与传动杆220的轴线之间的夹角为锐角，也即，传动杆220的轴线并不垂直于端面232，这样能提高滑块230的受力情况，减少摆动件240与滑块230的磨损。
而且，滑块230包括螺母231及端盖233，螺母231与传动杆220螺纹连接，端盖233设于螺母231的一端，并与摆动件240抵接。可以理解地，端盖233与摆动件240抵接的一面即为端面232。在本实施方式中，螺母231与端盖233可拆卸连接，这样能够避免摆动件240与螺母231直接抵接，以防螺母231磨损，若端面232受损严重，可以只更换端盖233，从而能降低检修成本。当然，在其他实施方式中，端盖233也可以省略，此时，摆动件240直接抵接在滑块230上。
值得一提的是，对于不同形式的目标结构，本实施方式的双马达驱动器10同样适用。
为了保证安全性能，本实施方式的双马达驱动器10具备限制滑块230行程的功能，具体表现为限制滑块230运动的极限位置。
具体地，如图2、图4、图7及图8所示，控制组件300包括电路板302及电气开关304，电路板302安装在控制盒120内，并通过电连接组件400与马达210电性连接，电路板302还与手控器14电性连接。电气开关304包括第一行程开关310和第二行程开关320，第一行程开关310和第二行程开关320均与电路板302电性连接。驱动机构200还包括制动件260，制动件260与滑块230连接，滑块230运动时会带动制动件260一起运动。制动件260能与第一行程开关310配合，以控制滑块230的第一极限位置，制动件260还能与第二行程开关320配合，以控制滑块230的第二极限位置。
更为具体地，第一行程开关310包括相互连接的第一开关主体312及第一触点314，第二行程开关320包括相互连接的第二开关主体322及第二触点324，第一行程开关310与第二行程开关320均设于控制盒120内，第一触点314及第二触点324均能通过对应的弹簧相对于控制盒120伸缩，且均凸出于第二表面124，第一触点314与第二触点324沿第一方向间隔设置。其中，第一触点314对应控制第一极限位置，第二触点324对应控制第二极限位置。
在本实施方式中，主壳体110上设有与容置腔112连通的条形槽118，制动件260滑动设置在条形槽118内，条形槽118的延伸方向平行于第一方向，也即，制动件260的运动方向平行于第一方向，制动件260滑动设置在条形槽118内，从而制动件260在运动时会更加稳定。第一触点314及第二触点324均延伸至条形槽118内，以与制动件260配合。
请一并结合图10，制动件260包括沿第一方向依次设置的第一导引面261、延伸面262及第二导引面263，延伸面262连接在第一导引面261与第二导引面263之间。第一导引面261能够导引第一触点314，以改变第一触点314的伸缩状态，第二导引面263能够导引第二触点324，以改变第二触点324的伸缩状态。制动件260上设有分别设于延伸面262两侧的第一凹槽264及第二凹槽265，第一导引面261为第一凹槽264的一内侧壁，第二导引面263为第二凹槽265的一内侧壁。
滑块230在第一极限位置与第二极限位置之间运动时，第一触点314及第二触点324均与延伸面262抵接，且第一触点314和第二触点324均处于收缩状态。滑块230运动至第一极限位置时，第一触点314伸入第一凹槽264内，滑块230运动至第二极限位置时，第二触点324伸入第二凹槽265内。容易理解地是，当滑块230在第一极限位置和第二极限位置之间运动时，第一触点314和第二触点324都处于收缩状态；而当滑块230在第一极限位置时，第一触点314处于伸出状态，第二触点324仍与延伸面262抵接而处于收缩状态；当滑块230在第二极限位置时，第二触点324处于伸出状态，第一触点314仍与延伸面262抵接而处于收缩状态。而且，以图9为观察视角，第一极限位置位于左侧，第二极限位置位于右侧，也即，第一极限位置比第二极限位置更靠近马达210。
在本实施方式中，第一导引面261能够起导引作用，使得第一触点314能由第一凹槽264内再次回到与延伸面262抵接的状态，也即，第一导引面261能对滑块230从第一极限位置向第二极限位置运动起导引作用。第二导引面263也是能够起导引作用，使得第二触点324能由第二凹槽265内再次回到与延伸面262抵接的状态，也即，第二导引面263能对滑块230从第二极限位置向第一极限位置运动起导引作用。
而当滑块230运动至第一极限位置时，马达210停止运转，用户通过操作手控器14，可以使得马达210反转从而使得滑块230朝向第二极限位置运动。同样地，当滑块230运动至第二极限位置时，马达210停止运转，用户通过操作手控器14，可以使得马达210反转从而使得滑块230朝向第一极限位置运动。
在其他实施方式中，还可以改变第一行程开关310与第二行程开关320的触发方式，例如，在第一导引面261和第二导引面263之间设置一个凹槽，当第一触点314与第二触点324都伸入在这个凹槽内时，滑块230在第一极限位置和第二极限位置之间运动，当第一触点314沿着第一导引面261离开该凹槽后，表明滑块230运动至第一极限位置，此时，第二触点324仍伸入在凹槽内，当第二触点324沿着第二导引面263离开该凹槽后，表明滑块230运动至第二极限位置，此时，第一触点314仍伸入在凹槽内。
可以理解的，第一行程开关310与第二行程开关320的数目均设有两个，一个第一行程开关310与一个第二行程开关320对应一组驱动机构200。
进一步，在本实施方式中，第一极限位置与第二极限位置中的至少一个可调，以适用于不同类型的目标结构。
具体地，请结合图10和图11，制动件260包括制动本体270及与制动本体270可拆卸连接的调节件280，制动本体270包括第一抵接面272，调节件280包括第二抵接面282，第二抵接面282与第一抵接面272对接以形成延伸面262，调节件280包括第一导引面261与第二导引面263中的至少一个，第一凹槽264与第二凹槽265中的至少一个设于调节件280上。
为方便理解，定义制动本体270包括依次设置的第一导引斜面271、第一抵接面272及第二导引斜面273，同时，制动本体270上还设有分别位于第一抵接面272两侧的第一安装槽274和第二安装槽275。调节件280包括依次连接的过渡斜面281和第二抵接面282，调节件280上还设有横槽283。
当调节件280的数量为0时，制动本体270即作为制动件260。当调节件280的数量为1时，且设置在第一安装槽274内时，第二安装槽275即为第二凹槽265，第二导引斜面273即为第二导引面263，第一抵接面272与第二抵接面282对接形成延伸面262，横槽283即为第一凹槽264，过渡斜面281则作为第一导引面261。当调节件280的数量为1时，且设置在第二安装槽275内时，同理，在此不进行赘述。当调节件280的数量为2时，其中一个调节件280设置在第一安装槽274内，另一个调节件280则设置在第二安装槽275内，此时，两个调节件280的第二抵接面282与第一抵接面272共同构成延伸面262，其中一个调节件280的横槽283作为第一凹槽264，另一个调节件280的横槽283作为第二凹槽265，其中一个调节件280的过渡斜面281作为第一导引面261，另一个调节件280的过渡斜面281作为第二导引面263。
也即，调节件280的有无以及调节件280设置的个数决定了延伸面262在第一方向上的尺寸，从而决定了滑块230的行程大小。同时，通过更换具有不同延伸长度的第二抵接面282的调节件280，也能改变延伸面262的延伸长度。
当然，在其他实施方式中，调节件280也可以直接省略，通过更换制动件260的规格即可，也即，使得制动件260与滑块230可拆卸连接也能实现滑块230行程的调节。
请参考图8及图9，在本实施方式中，传动杆220的轴线沿第二方向延伸，第一方向与第二方向成夹角设置，因此，滑块230的运动方向与制动件260的运动方向不一致，为了使得滑块230带动制动件260顺利运动，驱动机构200还设置了转接件290，转接件290与滑块230连接，制动件260与转接件290滑动配合。
具体到本实施例中，转接件290与滑块230固定连接，转接件290上设有滑槽292，制动件260滑动设置在滑槽292上。以图9所示为观察视角，当滑块230带动制动件260向右移动时，转接件290会相对于制动件260向上移动；当滑块230带动制动件260向左移动时，转接件290会相对于制动件260向下移动。
在其他实施方式中，也可以使得转接件290的一端与滑块230转动连接，另一端与制动件260转动连接。
对于本实施方式的双马达驱动器10来说，转接件290的设置使得制动件260与滑块230的配合变得更为灵活，从而制动件260与滑块230能在主壳体110内布置得更为紧凑，进而能减小双马达驱动器10占用的空间。
进一步，转接件290设于滑块230靠近马达210的一端，这样，在使得驱动机构200的结构更为紧凑的基础上，还能保证滑块230的行程范围足够大。
另外，还可以将主壳体110的形状与驱动机构200的排布相匹配，以减小主壳体110的体积。
例如，在本实施方式中，主壳体110包括相对设置的第一侧面113及第二侧面115，第一侧面113的延伸方向平行于第一方向，第二侧面115的延伸方向平行于第二方向，滑块230位于制动件260与第二侧面115之间，第一极限位置与第一侧面113之间的距离大于第二极限位置与第一侧面113之间的距离。相比于长方体状的主壳体，本实施方式的主壳体110的体积更小。
如图4及图7所示，电连接组件400包括第一电连接器410及第二电连接器420，第一电连接器410设于主壳体110上，并与驱动机构200电性连接，第二电连接器420设于控制盒120上，并与电路板302电性连接，第二电连接器420与第一电连接器410插接配合。电连接组件400的结构简单，还不会妨碍主壳体110与控制盒120的拆卸。
一实施例中，第一电连接器410为插头，第二电连接器420为插座。另一实施例中，第一电连接器410为插座，第二电连接器420为插头。
值得一提的是，在本实施方式中，手控器14可以与电路板302有线连接，也可以与控制组件300无线连接。而且，手控器14作为驱动器本体的配件，若损坏，可以直接进行更换。
综合前面的描述，可以看出，电路板302及电气开关304均安装在控制盒120内，再加上控制组件300的其它电子元器件也都安装在控制盒120内，从而大大减轻了主壳体110内的布线负担，不仅方便检修，还有利于提高双马达驱动器10的性能。
如图3所示，为使得控制盒120的功能满足更多用户的需求，在控制盒120上还设置了多个扩展接口129，各扩展接口129均与电路板302电性连接，这些扩展接口129可以连接备用电池，可以连接手控器14，还可以连接其他的驱动器以共用一个控制盒120或一个手控器14，还可以作为USB接口进行充电等等。扩展接口129的数目可以根据用户的需要进行配置。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
