技术领域
本申请涉及到移动终端技术领域，尤其涉及到一种间歇抬升组件及移动终端。
背景技术
随着笔记本电脑的功耗越来越大，以及游戏本的性能提升，对散热要求也越来越高，大功耗产生的热量散不出去成为制约着笔记型电脑性能提升瓶颈之一，散热性能也成为笔记型电脑关键指标。
现有技术传统方法通过将CPU等热源先传到散热器，再通过风扇散热，随着功耗增加，风扇转速提高，风扇带来的噪音也越大，用户的体验不佳，一般笔记型电脑外观开孔较小，进风量受到进风口限制，散热能力也达到极限，制约着笔记型电脑性能提升。为了更进一步的提高散热的效果，在笔记本电脑的壳体上增加了一个散热板，该散热板与壳体转动连接，在需要进行散热时，打开散热板来增大进风量，从而增大散热的效果。但是现有技术中驱动散热板打开的机构比较复杂，且占用的空间比较大，影响笔记本电脑的尺寸。
发明内容
本申请提供了一种间歇抬升组件及移动终端，用以降低散热板驱动机构的尺寸，降低占用的移动终端内的空间。
第一方面，提供了一种间歇抬升组件，该间歇抬升组件用于带动移动终端的散热板开合，其主要包括三个部件：第一驱动件、第二驱动件以及摆杆。其中，第一驱动件与移动终端的显示屏连接，且第一驱动件带动第二驱动件转动，第二驱动件与摆杆固定连接，而该摆杆与散热板滑动连接，通过摆杆的转动可以带动散热板转动，以实现打开和闭合的效果。在具体设置时，该第一驱动件包括第一间歇齿轮，以及设置在所述第一间歇齿轮的凸肩；而第二驱动件包括一个第二间歇齿轮，且该第二间歇齿轮与第一间歇齿轮啮合，以实现间歇运动。此外，为实现对散热板打开时进行锁定的效果，在所述第二间歇齿轮上设置有限位槽；所述限位槽用于限定所述凸肩在所述第一间歇齿轮与所述第二间歇齿轮的齿脱离啮合状态下滚动的位置；且所述凸肩上设置有用于避让所述第二间歇齿轮的缺口。在具体设置该限位槽时，其个数可以为一个也可以为两个。如在该第二间歇齿轮上设置有两个间隔设置的限位槽，并且两个限位槽分别用于限定所述凸肩在所述第一间歇齿轮与所述第二间歇齿轮的齿啮合之前及啮合之后滚动的位置；在第一驱动件与第二驱动件配合时，第一间歇齿轮的凸肩在其中的一个限位槽中转动，当转动到一定角度时，第一间歇齿轮的齿与第二间歇齿轮的齿啮合，第一间歇齿轮继续转动，带动第二间歇齿轮转动，第二间歇齿 轮带动摆杆转动，以驱动散热板打开，同时，凸肩由所在的限位槽滚动到另外的一个限位槽中，并且为了跨越两个限位槽之间的间隔的凸起，该凸肩上设置有用于避让所述两个限位槽之间间隔的凸起的缺口；从而在第一间歇齿轮与第二间歇齿轮的齿在脱离啮合时，凸肩能够滚动到另外的一个限位槽中。在凸肩位于另外的一个限位槽中时，凸肩可以继续相对第二间歇齿轮转动，此时，由于第一间歇齿轮的齿与第二间歇齿轮的齿脱离啮合，因此不会带动第二间歇齿轮转动，同时，由于凸肩位于另一个限位槽中，因此可以锁定第二间歇齿轮，避免第二间歇齿轮转动，从而可以通过摆杆使得散热板保持在打开的位置，实现了对散热板位置的锁定。
在具体设置第一间歇齿轮及第二间歇齿轮时，所述第一间歇齿轮包括有N个全齿，所述第二间歇齿轮包括N-1个全齿以及位于所述N-1个全齿两侧的两个半齿；其中，N为大于2的正整数。如第一间歇齿轮具有两个全齿，而第二间歇齿轮具有一个全齿，以及位于该全齿两侧的两个半齿。通过设置的第一间歇齿轮及第二间歇齿轮的齿数来确定第二间歇齿轮的转动角度。
在具体设置两个间隔的限位槽时，该限位槽为弧形的限位槽，且两个限位槽位于第二间隔齿轮的齿的两侧。

当然，第二间歇齿轮还可以采用其他结构，如摆杆与所述第二间歇齿轮为一体结构。该摆杆的个数为两个，且分列在第二间歇齿轮的两侧。
在具体设置摆杆时，所述摆杆远离所述第二间歇齿轮的一端设置有用于与所述散热板滑动配合的滚轮。通过滚轮与散热板滑动连接，降低了摩擦阻力。
在设置凸肩时，所述凸肩上设置有对位凸起，所述第二间歇齿轮上设置有与所述对位凸起配合的对位凹槽；在所述对位凸起与所述对位凹槽配合时，所述第一间歇齿轮与所述第二间歇齿轮的齿对齐到啮合位置。通过设置的对位凸起与对位凹槽的配合，提高了第一间歇齿轮与第二间歇齿轮的啮合效果。
在一个具体的可实施方案中，所述第一驱动件还包括与所述第一间歇齿轮固定连接的第一支架，所述第一支架用于与所述移动终端的显示屏固定连接。通过第一支架实现与显示屏的固定连接。
在一个具体的可实施方案中，所述第二驱动件还包括与所述第二间歇齿轮固定连接的第二支架，所述第二支架用于与所述移动终端的壳体固定连接。通过设置的第二支架实现了第二间歇齿轮与壳体的转动连接。
为了提高凸肩与限位槽的配合效果，在所述限位槽内设置有储油槽，以提高凸肩的滚动效果。
在一个具体的可实施方案中，该间歇抬升组件还包括与所述第二间歇齿轮同轴固定连接杆，所述连杆上设置有用于抵压所述散热板的折弯结构。通过该折弯结构一起推动散热板的开合。
在一个具体的实施方案中，所述折弯结构上套装有滚筒182。提高了控制开合的效果。
第二方面，提供了一种移动终端，该移动终端包括本体以及与所述本体转动连接的显示屏，还包括上述任一项所述的间歇抬升机构，其中，所述第一间歇齿轮与所述显示屏固定连接；所述本体包括壳体以及与所述壳体转动连接的散热板；所述第一间歇齿轮及所述第二间歇齿轮与所述壳体转动连接，且所述摆杆与所述散热板滑动连接并用于推动所述散热板转动。
在上述技术方案中，通过采用第一驱动件及第二驱动件带动散热板转动以实现开合，并将散热板锁定在所需的位置，简化了驱动机构的结构，降低了占用的空间面积。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
为了方便理解本申请实施例提供的间歇抬升组件，首先说明一下其应用场景。如图1及图2中所示，本申请实施例提供的间歇抬升组件10应用于移动终端100上，如笔记本电脑上。该笔记本电脑包括本体以及与所述本体转动连接的显示屏20，其中，该本体用于盛放主板、硬盘、处理器等结构，其连接关系与现有技术中的连接关系相同，在此不予赘述。此外，本体包括一个壳体30，该壳体30包括第一壳体33，与第一壳体33连接的第二壳体32；其中，第一壳体33及第二壳体32围成容纳上述盛放主板、硬盘、处理器等结构的空间。如图3中所示，其中的第二壳体32转动连接了一个散热板31，该散热板31用于增大移动终端100的进风量。在使用时如图1及图2所示，首先参考图1，在移动终端 100不使用时，显示屏20盖合，此时散热板31关闭。如图2中所示，在移动终端100使用时，显示屏20打开，同时通过间歇抬升组件10来带动散热板31转动打开，从而增大本体内的进风量。在上述运动过程中，间歇抬升组件10具有两个工作过程，其一是在显示屏20转动时，带动散热板31转动打开，其二是在散热板31转动打开后，使得散热板31能够保持打开状态，并且解锁散热板31与显示屏20的联动关系。
为了方便理解该间歇抬升组件10，首先参考图4其中，图4中示出了该间歇抬升组件10的结构。该间歇抬升组件10主要包含三个部件：第一驱动件11、第二驱动件12以及摆杆15。为了方便理解本申请实施例提供的间歇抬升组件10，下面结合图4、图5及图6介绍说明一下该间歇抬升组件10的结构。
首先参考图5及图6，其中图5及图6分别示出了第一驱动件11及第二驱动件12的结构。第一驱动件11及第二驱动件12分别包含一个间歇齿轮，为方便面描述，将第一驱动件11包含的间歇齿轮命名为第一间歇齿轮111，第二驱动件12包含的间歇齿轮命名为第二间歇齿轮121。如图4中所示，在第一驱动件11与第二驱动件12配合时，该第一间隙齿轮及第二间歇齿轮121的齿啮合。在使用时，一并参考图3及图4，其中，第一驱动件11与显示屏20固定连接，在具体连接时，如图4中所示，该第一间歇齿轮111套装在一个转轴17上，并可与该转轴17同步转动，此外，该转轴17的另一端固定连接有一个第一支架13，该第一支架13与显示屏20固定连接。从而在显示屏20相对壳体30转动时，连接板可以通过转轴17带动第一间歇齿轮111同步转动。而在设置第二驱动件12时，该第二驱动件12与第一壳体33固定连接，并且其包含的第二间歇齿轮121可相对壳体30转动，如图3及图4中所示，该第二驱动件12包括一个第二支架14，第二间歇齿轮121与该第二支架14转动连接，在与移动终端100配合时，该第二支架14固定在壳体30上。此外，间歇抬升组件10的摆杆15与第二间歇齿轮121固定连接，并可与该第二间歇齿轮121同步转动，该摆杆15在装配时与散热板31滑动连接，在第二间歇齿轮121转动时，带动摆杆15转动，进而通过摆杆15与散热板31的滑动带动散热板31相对壳体30转动。
为了方便该间歇抬升组件10的使用情况，首先说明一下两个间歇齿轮的配合。一并参考图5及图6，该第一间歇齿轮111及第二间歇齿轮121上的齿的设置方式不同，其中第一间歇齿轮111的齿为外凸形成的齿，而第二间歇齿轮121的齿为内凹形成的齿。在具体形成时，该第一间歇齿轮111包括一个第一圆柱体，第一间歇齿轮111的齿外凸在该第一圆柱体外。如图6中所示，第二间歇齿轮121包括一个第二圆柱体，第二间歇齿轮121的齿是在第二圆柱体上开设凹槽形成的齿。该第一驱动件11及第二驱动件12分别用于与壳体30及显示屏20固定连接，并且第二驱动件12中的第二间歇齿轮121可以相对壳体30转动。在显示屏20打开及关闭时，显示屏20可带动第一驱动件11转动，而第一驱动件11带动第二驱动件12转动。在具体实现时，一并参考图7及图8，其中图7及图8示出了第一间歇齿轮111与第二间歇齿轮121的齿在配合时的状态。如图7所示，第一间歇齿轮111及第二间歇齿轮121的齿啮合，此时，通过啮合的齿可以使得第一间歇齿轮111与第二间歇齿轮121相对转动。如图8中所示，在转动到一定位置时，第一间歇齿轮111及第二间歇齿轮121的齿脱离啮合，此时，第一圆柱体及第二圆柱体之间接触，或者第一圆柱体与第二圆柱体之间具有一定的间隙。
在具体设置第一间歇齿轮111及第二间歇齿轮121的齿时，对于每个间歇齿轮的齿可以设置不同的个数，但是其齿数之间具有一定的配合关系。如在具体设置时，第一间歇齿 轮111上设置了N个全齿，对应的第二间歇齿轮121上设置了N-1个全齿；其中，N为大于2的正整数。以图5及图6中所示的结构为例，其中，第一间歇齿轮111上设置了四个全齿，第二间歇齿轮121上设置了3个全齿以及两个半齿。当然图5仅仅示出了一个具体的实际的情况，第一间歇齿轮111上的齿的个数可以为三个、五个、六个等不同正整数个齿。对应的第二间歇齿轮121上也可以设置两个、四个、五个等不同个数的全齿。应当理解的是，上述第一间歇齿轮111与第二间歇齿轮121齿数关系不仅限于上述的限定，两者之间还可以差三个齿、四个齿等不同的齿数。
由图7及图8可以看出，在第一驱动件11及第二驱动件12转动到一定位置时，第一间歇齿轮111及第二间歇齿轮121的齿脱离啮合状态，如图8中所示的状态。为了接触散热板31与显示屏20之间的联动关系，并且使得散热板31保持在相对的打开位置。在本申请实施例提供的方案中第一驱动件11及第二驱动件12之间设置了一个配合结构。该配合结构包括两个结构：凸肩112以及限位槽122；其中，凸肩112第一间歇齿轮111的一端并与第一间歇齿轮111同轴设置。在具体设置时，该凸肩112可以与第一圆柱体为一个结构，也可以采用分体结构，此时凸肩112套装在第一圆柱体上并进行固定。继续参考图5，该凸肩112为圆柱形，并且该凸肩112上设置有一个缺口113，该缺口113用于避让第二间歇齿轮121。在设置该缺口113时，如图5中所示，该缺口113的设置位置与第一间歇齿轮111的齿的位置相对应。在具体对应时，为方便描述引入第一平面，该第一平面为凸肩112背离第一间歇齿轮111的面所在的平面，其中，第一间歇齿轮111上的齿在第一平面的垂直投影落入在所述缺口113在所述第一平面的垂直投影内。以便于在第一间隙齿轮的齿与第二间歇齿轮121的齿啮合时，设置的凸肩112不会影响到齿的啮合，如图7中所示，图7示出了在啮合状态时，缺口113与两个间歇齿轮的齿的相对位置关系。由图7可看出，在两个间歇齿轮的齿啮合时，缺口113的位置转动与第二间歇齿轮121的齿相对的位置，从而避免设置的凸肩112碰到第二间歇齿轮121。
一并参考图8，在图8所示的结构中，第一间歇齿轮111与第二间歇齿轮121的齿脱离啮合状态，此时凸肩112上的缺口113转过，凸肩112开始朝向第二间歇齿轮121。为了避免凸肩112与第二间歇齿轮121之间出现干涉，同时为了限定所述凸肩112在所述第一间歇齿轮111与所述第二间歇齿轮121的齿脱离啮合状态下滚动的位置，在第二间歇齿轮121上设置了一个限位槽122。该限位槽122可以限位第一驱动件11的滚动。在具体设置该限位槽122时，如图6中所示的结构，该限位槽122设置在了第二圆柱体的一端，且该限位槽122为一个弧形的限位槽122，在具体形成时，通过在第二圆柱体的一端开设一个弧形的缺口113形成该限位槽122，且该弧形的限位槽122的圆心与凸肩112的圆心为同一个圆心。在装配时，限位槽122与凸肩112的位置相对。一并参考图7及图8，在第一间歇齿轮111及第二间歇齿轮121的齿啮合时，凸肩112上的缺口113与第二间歇齿轮121相对，在第一间歇齿轮111继续转动时，如图8中所示，第一间歇齿轮111与第二间歇齿轮121的齿脱离接触，此时，凸肩112转动到限位槽122中，并可在限位槽122中滚动，并且为了降低滚动时的摩擦，设置时在限位槽122内设置有储油槽，以提高凸肩112的滚动效果。在显示屏20转动时，带动第一驱动件11在限位槽122中转动，同时，由于限位槽122与凸肩112的配合，限制了第二间歇齿轮121的转动，使得第二间歇齿轮121保持在该转动的位置。而第二间歇齿轮121与散热板31之间具有相对的位置关系。因此，在第二间歇齿轮121保持不转动时，散热板31的状态也不会改变。
应当理解的时，上述的脱离啮合状态指的是：第一间歇齿轮111与第二间歇齿轮121在啮合前的状态、第一间歇齿轮111与第二间歇齿轮121在啮合后的状态。该限位槽122的个数可以根据实际需要进行设置，既可以采用设置一个限位槽122，也可以采用设置两个限位槽122。在图6中示出了设置在第一间歇齿轮111及第二间歇齿轮121脱离状态后的限位槽122的位置。在采用两个限位槽122时，分别在第一间歇齿轮111与第二间歇齿轮121啮合前及啮合后对应的位置设置限位槽122。
为了方便理解上述第一间歇齿轮111与第二间歇齿轮121的配合效果，下面结合图9a～图9f对其转动情况进行说明。首先参考图9a，以图9a中所示的箭头为例，其中第一间歇齿轮111逆时针转动，同时带动第二间歇齿轮121顺时针转动，并且该摆杆15处于水平的位置。并且在图9a中所示的第一间歇齿轮111与第二间歇齿轮121的第一个齿开始啮合。在显示屏20继续转动时，如图9b中所示，在第一间歇齿轮111转动一定角度时，第二间歇齿轮121也顺时针转动一定角度，同时带动摆杆15转动相应的角度，一并参考图2，在摆杆15转动的同时，会带动散热板31转动，从而使得散热板31打开。继续参考图9c，在第一间歇齿轮111继续转动时，第一间歇齿轮111与第二间歇齿轮121的齿脱离啮合状态，此时第一驱动件11的凸肩112正好转动到第二驱动件12的限位槽122中，在第一间歇齿轮111与第二间歇齿轮121脱离啮合后，凸肩112与限位槽122开始配合；继续参考图9d，在第一间歇齿轮111继续转动时，该凸肩112在第二驱动件12的限位槽122中滚动，并且第二间歇齿轮121保持与图9c中的位置一致，同样的摆杆15的位置也保持不变。对应到图2中的结构即为：在显示屏20转动打开到一定位置时，由于摆杆15的位置不变，因此散热板31的打开状态保持。继续参考图9f，在图9f中示出了在移动终端100关闭时第一间歇齿轮111与第二间歇齿轮121的配合情况，此时，第一间歇齿轮111开始顺时针转动，并且在第一间歇齿轮111与第二间歇齿轮121啮合时，第一间歇齿轮111带动第二间歇齿轮121转动，此时第二间歇齿轮121开始逆时针转动。对应图2中的结构，此时显示屏20朝向壳体30转动，以关闭整个移动终端100，在关闭的过程中，第一间歇齿轮111带动第二间歇齿轮121转动，同时摆杆15也跟随第二间歇齿轮121转动，在摆杆15转动的同时带动散热板31关闭，从而关闭进风口。由上述描述可以看出，通过第一间歇齿轮111与第二间歇齿轮121的配合，可以改善散热板31与显示屏20的联动效果。如以第一间歇齿轮111全程0～150度转动为例，第二间歇齿轮121在第一间歇齿轮111转动0～30度时不跟随第一间歇齿轮111不转动(第一间歇齿轮111与第二间歇齿轮121还没啮合)、第二间歇齿轮121在第一间歇齿轮111转动30～60度时跟随第一间歇齿轮111一起转动(第一间歇齿轮111与第二间歇齿轮121啮合)、在第一间歇齿轮111转动到60～150度时第二间歇齿轮121不跟随第一间歇齿轮111转动(第一间歇齿轮111与第二间歇齿轮121脱离啮合，但是摆杆15处于推动散热板31打开的状态)。从而可以解放出来显示屏20的转动，避免散热板31一直跟随显示屏20转动，提高了移动终端100在使用时的效果。应当理解的是，上述中的第一间歇齿轮111的转动角度仅仅为一个示例，可以根据需要调整第一间歇齿轮111与第二间歇齿相对转动的角度，在具体设置时，只需要根据实际需要调整设置的齿即可。
在具体设置上述第二间歇齿轮121时，第二间歇齿轮121可以采用不同的结构。如采用一体结构或者采用分体结构。首先继续参考图6，在图6设置的结构中，该第二间歇齿轮121采用一体结构，此时，第二间歇齿轮121包括上述中的一个第二圆柱体，并且第二 圆柱体上设置齿。此外，该第二圆柱体的两端分别设置了轴，该轴用于与第二支架14转动连接。在设置摆杆15时，如图6中所示，该摆杆15与第二间歇齿轮121采用一体结构，在图6中所示的结构中摆杆15的个数为两个，且分列在第二间歇齿轮121的两侧。在具体设置时，两个摆杆15分别通过滚轮16与散热板31滑动连接。在具体设置滚轮16时，该滚轮16设置在了摆杆15远离第二间歇齿轮121的一端。此外，在具体滑动连接时，该散热板31上设置有与该摆杆15对应配合的滑轨311，所述滑轨311为曲线滑轨，曲线滑轨是为了调节显示屏20打开时，系统的升降速度，具体到本案例就是匀速打合显示屏20时，系统匀速升降。而滑轨311与滚轮16的具体滑动装配为现有技术中常见的技术手段，在此不再赘述。
除了上述的一体结构外，该第二间歇齿轮121还可以采用分体结构，具体的可以参考图10及图11所示，其中图10示出了第二间歇齿轮121的结构示意图，图11示出了其分解示意图。此时该第二间歇齿轮121包括多个钣金片125，且多个钣金片125层叠设置排列成柱状结构，并且通过一个转轴(图中未示出)穿设。此外每个钣金片125上设置有齿；在多个钣金片125层叠穿设在转轴时，多个钣金片125的齿对应，并且组成第二间歇齿轮121。此外，摆杆15的个数也为两个，并且摆杆15套装在转轴上且位于第二间歇齿轮121的端部。通过上述描述可以看出，在具体设置第二间歇齿轮121时，可以通过采用钣金件组装成第二间歇齿轮121。同时在组装时，摆杆15也可以采用组装件，在第二间歇齿轮121组装时，与钣金件一起组装在一起。在具体组装时，该转轴上设置有用于限定钣金件以及摆杆15在轴向上的限位结构，该限位结构可以为卡簧或者轴上的凸肩等不同的结构，只需要能够限定钣金件与摆杆15的运动即可，并且上述限位结构为现有技术中的常见的结构，因此在此不予赘述。
一并参考图12，在图12中示出了采用第二驱动件12为分体结构时的间歇抬升组件10的结构。在装配时，通过上述的转轴将第二间歇齿轮121与第二支架14转动连接，并且摆杆15上穿设了一个转轴，该转轴上设置滚轮16，以用于与散热板31滑动连接，并且设置的滚轮16还可以降低在滑动时的摩擦力。
继续参考图2，由图2可以看出，该散热板31为一个长条状结构，而本申请实施例提供的摆杆15在与散热板31配合时，只能推动散热板31的一端。为了改善推动散热板31的效果，在具体设置摆杆15时，如图13中所示，第二间歇齿轮121同轴固定了一个连接杆18，连杆上设置有用于抵压散热板31的折弯结构181。继续参考图13，在设置该连接杆18时，该连接杆18的长度方向与第二间歇齿轮121与第二支架14转动连接时的转轴的长度方向相同，即连接杆18的长度方向沿散热板31的长度方向(该散热板31的长度方向指的是散热板31在与壳体30转动连接时所绕的轴线的长度方向)。并且该第二滚轮16在与散热板31装配时，也采用滑动装配的方式，从而可以使得滚轮16与第二滚轮16可以分别推动散热板31的两端转动。
继续参考图5及图6，在第一间歇齿轮111及第二间歇齿轮121配合时，需要进行齿对位，为了保证第一间歇齿轮111及第二间歇齿轮121的齿能够对位准确，在设置凸肩112时，该凸肩112上设置有对位凸起114，并且对应的在第二间歇齿轮121上设置有与对位凸起114配合的对位凹槽123。该对位凸起114与对位凹槽123在配合时，使得第一间歇齿轮111与第二间歇齿轮121的齿对齐到啮合位置。具体可以参考图9a～图9f，首先如图9a中所示，在第一间歇齿轮111与第二间歇齿轮121啮合转动时，对位凸起114位于对位 凹槽123外，并且对位凸起114与对位凹槽123相向转动。如图9b所示，随着第一间歇齿轮111及第二间歇齿轮121的相对转动，对位凸起114逐步进入到对位凹槽123中，如图9c所示，在第一间歇齿轮111及第二间歇齿轮121脱离接触后，对位凸起114及对位凹槽123开始脱离接触。如图9d中所示，在第一间歇齿轮111继续转动时，对位凸起114从对位凹槽123中滑出。如图9f，在第一间歇齿轮111及第二间歇齿轮121反向转动时，首先对位凸起114进入到对位凹槽123中，通过对位凸起114与对位凹槽123的对位，使得第一间歇齿轮111及第二间歇齿轮121的齿能够对位到啮合，保证了在第一间歇齿轮111与第二间歇齿轮121脱离啮合状态后再次进行啮合时，能够保证第一间歇齿轮111与第二间歇齿轮121可以准确的啮合。提高了第一间歇齿轮111与第二间歇齿轮121的啮合效果。并且该对位凸起114与对位凹槽123还可以实现调整第一间歇齿轮111及第二间歇齿轮121的效果，在两者出现偏离时，通过对位凸起114与对位凹槽123的配合将第一间歇齿轮111复位，从而保证齿轮准确啮合。
通过上述实施例可以看出，在本申请公开的间歇抬升组件通过采用驱动散热板31开合实现壳体内散热用的腔体的开合。在上述实施例中，以移动终端设置有散热板31为例进行的说明，但是在本申请实施例提供的间歇抬升组件不仅限于应用在上述移动终端，在移动终端采用其他的方式时，也可以采用本申请实施例提供的间歇抬升组件。如移动终端的壳体仅包含第一壳体及第二壳体，并且第一壳体与第二壳体围成容纳主板、硬盘等器件的空间。此外，第一壳体及第二壳体转动连接，而显示屏与第一壳体转动连接；此时，间歇抬升组件中的第一驱动件与显示屏固定连接，而第二驱动件连接的推杆与第二壳体滑动连接，此时第二壳体作为散热板；或者，显示屏与第二壳体转动连接；此时，间歇抬升组件中的第一驱动件与显示屏固定连接，而第二驱动件连接的推杆与第一壳体滑动连接，此时，第一壳体作为散热板。在采用上述结构时，第一驱动件及第二驱动件与显示屏以及第一壳体或第二壳体的配合关系可以参考上述实施例中第一驱动件与显示屏的连接，以及第二驱动件与散热板的连接。在采用上述结构时，间歇抬升组件同样可以实现间歇运动，以控制散热腔体的开合。
此外，如图14所示，本申请的实施例还提供了一种移动终端100，该移动终端100可以为笔记本电脑。在具体设置时，该笔记本电脑包括本体以及与所述本体转动连接的显示屏20，其中，该本体用于盛放主板、硬盘、处理器等结构，其连接关系与现有技术中的连接关系相同，在此不予赘述。此外，本体包括一个壳体30，该壳体30包括第一壳体33，与第一壳体33连接的第二壳体32；其中，第一壳体33及第二壳体32围成容纳上述盛放主板、硬盘、处理器等结构的空间。如图3中所示，其中的第二壳体32转动连接了一个散热板31，该散热板31用于增大移动终端100的进风量。在移动终端100不使用时，显示屏20盖合，此时散热板31关闭。在移动终端100使用时，显示屏20打开，同时通过间歇抬升组件10来带动散热板31转动打开，从而增大本体内的进风量。在具体设置该间歇抬升组件10时，如图15中所示，第一间歇齿轮111与显示屏20固定连接；第一间歇齿轮111及第二间歇齿轮121与壳体30转动连接，且摆杆15与散热板31滑动连接并用于推动散热板31转动。具体的连接方式可以参考上述中的描述。在上述运动过程中，间歇抬升组件10具有两个工作过程，其一是在显示屏20转动时，带动散热板31转动打开，其二是在散热板31转动打开后，使得散热板31能够保持打开状态，并且解锁散热板31与显示屏20的联动关系。通过上述描述可以看出，本申请实施例提供的移动终端100通过 采用第一驱动件11及第二驱动件12带动散热板31转动以实现开合，并将散热板31锁定在所需的位置，简化了驱动机构的结构，降低了占用的空间面积。
在具体设置间歇抬升机构时，为了改善推动散热板的效果，该间歇抬升机构的个数为两个，且两个间歇抬升机构对称设置。从而提高了散热板31的开合效果。
以上，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
