- the limit part 220 is in the limit position.
- the retractable module 100 and the limit part 220 are in position-limiting cooperation, and the elastic driving member 210 is deformed toward the retractable module 100.

- the telescopic module 100 returns to the retracted state described above.
- the flexible module 100 can be moved between the working state and the non-working state by moving the flexible module 100.
- the flexible module 100 does not occupy the area of the display area, thereby increasing the screen-to-body ratio of the terminal device.
- the telescopic movement of the telescopic module 100 does not require a motor and a transmission mechanism with a relatively complicated structure. Therefore, the terminal device disclosed in the embodiments of the present disclosure can solve the high cost of the telescopic module 100 in the related art. And the structure is more complicated.
- the above-mentioned limiting part 220 may specifically include a main body 221 and a limiting head 222 provided on the main body 221, and the main body 221 is connected to the magnetic driving part 230.
- the telescopic module 100 has a limiting boss 110. At the limit position, the limiting head 222 cooperates with the limiting boss 110 to limit the movement of the telescopic module 100. After the retractable module 100 is provided with the limit boss 110, the limit portion 220 and the retractable module 100 will not easily interfere with each other when they move, and the limit head 222 and the limit boss 110 are more easily matched.

- the limiting boss 110 of the telescopic module 100 has a second limiting plane 111.
- the first limiting plane 222a is attached to the second limiting plane 110, and the A limiting plane 222a and a second limiting plane 110 are both perpendicular to the moving direction of the telescopic module 100 (that is, the axial direction of the opening).
- the force between the first limit plane 222a and the second limit plane 110 can form the force that limits the telescopic module 100 to the greatest extent, so that the telescopic module 100 is more reliably maintained in the retracted state .
- connection relationship between the limit part 220 and the magnetic drive part 230 can be arranged in various ways. For example, when the magnetic drive part 230 does not generate magnetic force, there is a certain distance between the limit part 220 and the magnetic drive part 230. When the magnetic force 230 generates, the magnetic force is applied to the limiting portion 220 so that the limiting portion 220 is close to the magnetic driving portion 230 and further away from the telescopic module 100. However, with this structure, the force between the magnetic driving part 230 and the limiting part 220 is not well controlled, which may cause the limiting part 220 to be unable to move away from the telescopic module 100 quickly, or even to be separated from the telescopic module 100 .
- a concave portion 231 may be provided on the magnetic driving portion 230, and the main body portion 221 has a first force receiving convex portion 223. At least a part of the first force receiving protrusion 223 is located in the concave portion 231 of the magnetic driving portion 230, so that the main body 221 is connected to the magnetic driving portion 230 through the first force receiving protrusion 223.
- the magnetic driving portion 230 When the magnetic driving portion 230 generates a magnetic force, the portion of the magnetic driving portion 230 forming the recessed portion 231 will move, and then the first force-bearing convex portion 223 will drive the limiting portion 220 to move.
- the main body portion 221 also has a second force-receiving protrusion 224, and the linkage resetting member 240 can drive the limiting portion 220 from the second force-receiving protrusion 224.
- the release position moves to the limit position.
- the linkage reset member 240 drives the limiting portion 220 to move through the second force-bearing protrusion 224, so that the limiting portion 220 is close to the telescopic module 100 And it is coordinated with the telescopic module 100 in position limit.
- the linkage reset member 240 may include a rotating base 241 and a first end 242 and a second end 243 respectively disposed on opposite sides of the rotating base 241.
- the first end 242 here is used to contact the telescopic module 100 and bear the force exerted by the telescopic module 100
- the second end 243 is used to contact the second force-bearing protrusion 224 facing away from the telescopic module 100
- the limiting portion 220 is driven to move by the second force receiving convex portion 224.
- the linkage resetting member 240 is driven to rotate by the first end 242, and the second end 243 is driven by the second force-bearing protrusion 224 to drive the limiting portion 220 to move from the released position to the limiting position.
- the linkage reset member 240 is basically strip-shaped, its structure is relatively simple, and it occupies a smaller space, which facilitates the arrangement of the telescopic module 100, the limiting portion 220, the magnetic driving portion 230 and the linkage reset member 240.
- the above-mentioned second end 243 may be flush with the rotating base 241, and both form a straight rod-shaped structure. However, if this structure is adopted, the contact area between the second force-receiving protrusion 224 and the second end 243 will be relatively small, which is not conducive to the transmission of force, and it is also easy to contact the second force-receiving protrusion 224 and the second end 243. Scratches are formed on the surface of the second end 243, which negatively affects the precise expansion and contraction of the telescopic module 100. In order to solve this problem, the second end portion 243 may protrude outward in the radial direction of the rotating base 241 and toward the second force receiving protrusion 224. At this time, the surface structure of the second end portion 243 can be adjusted appropriately, so that the contact area between the second end portion 243 and the second force-receiving convex portion 224 is increased, thereby solving the aforementioned problem.
- a first arc-shaped force-receiving surface 224a may be provided on the second force-receiving convex portion 224, and a first arc-shaped force-applying surface 243a may be provided on the second end 243.
- the first arc-shaped force-receiving surface 224a is adapted to the first arc-shaped force-applying surface 243a, so that the second end 243 and the second force-receiving convex portion 224 are relatively slidable, and the two can maintain a larger contact area. This enhances the effect of force transmission while ensuring the integrity of the structure.
- a second arc-shaped force applying surface 120 may be provided on the telescopic module 100, and the first end 242 has a second arc-shaped force receiving surface 242a.

- first arc-shaped force receiving surface 224a first arc-shaped force applying surface 243a, second arc-shaped force receiving surface 242a, and second arc-shaped force applying surface 120 are all from actively applying force.
- the angles are named.
- the force-bearing surface may also be applied, and the force-applying surface may also be subjected to force. This article does not restrict it.
- the elastic driving member 210 is located on one side of the telescopic module 100, and the limiting component and the linkage reset member 240 are both located on the other side of the telescopic module 100.

为使本公开的目的、技术方案和优点更加清楚，下面将结合本公开具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
以下结合附图，详细说明本公开各个实施例公开的技术方案。
如图1至图3所示，本公开实施例公开一种终端设备，其包括壳体、伸缩模组100、弹性驱动件210、限位组件和联动复位件240。
壳体开设开口，具体地，壳体具有边框，该开口可以开设于边框的顶部。此开口可供伸缩模组100进出壳体，进而实现伸缩模组100的伸出和缩回。
伸缩模组100可移动地设置于壳体，进而通过开口进出壳体。该伸缩模组100相对于壳体伸出时，可以实现对应的功能；伸缩模组100相对于壳体缩回时，便收纳于壳体内。这种伸缩模组100不会占据终端设备的显示区域，因此终端设备的屏占比较大。本公开实施例中，伸缩模组100可以包括摄像头、传感器、指纹识别模组、受话器、补光灯中的至少一种。
弹性驱动件210具备弹性，其设置于壳体内。该弹性驱动件210可以与伸缩模组100抵靠或者连接在一起，当伸缩模组100受压而缩回壳体内时，伸缩模组100按压或者拉伸弹性驱动件210，使得弹性驱动件210发生变形，弹性驱动件210可以向伸缩模组100施加反作用力，即弹出力，在该弹出力的作用下，弹性驱动件210可以驱动伸缩模组100伸出壳体。弹性驱动件210可以设置为弹簧，终端设备还可以包括与伸缩模组100连接的导向杆250，弹性驱动件210套在该导向杆250的外部，其一端与导向杆250连接或者抵 靠，另一端与伸缩模组100连接或者抵靠。
限位组件设置于壳体内，其可以包括限位部220和磁性驱动部230。限位部220活动设置于壳体内，因此其可以在限位位置和释放位置之间可移动，磁性驱动部230可以驱动限位部220从限位位置向释放位置移动。当伸缩模组100需要保持缩回状态时，限位部220处于限位位置，此时限位部220与伸缩模组100配合，从而可以向伸缩模组100施加作用力，以克服弹性驱动件210施加于伸缩模组100的弹出力，达到限制伸缩模组100移动的目的，使得伸缩模组100无法弹出。当伸缩模组100需要伸出壳体时，限位部220处于释放位置，此时限位部220可以与伸缩模组100分离而撤去限位部220对于伸缩模组100的限位作用，从而释放伸缩模组以允许伸缩模组100移动，使得伸缩模组100可以弹出。
磁性驱动部230具体可以是电磁结构，其通电与断电时的磁性状态不同，进而可以通过磁性作用驱动限位部220移动。该磁性驱动部230可以与限位部220相连，也可以保持一定的距离，只要能够向限位部220施加磁力即可。
联动复位件240可以带动限位部220从释放位置向限位位置移动，使得限位部220可以在伸缩模组100缩回时再一次与伸缩模组100限位配合。具体地，联动复位件240可转动地设置于壳体内，伸缩模组100缩回壳体内时可以与联动复位件240的一端接触，从而带动联动复位件240转动，使得联动复位件240的另一端向限位部220施加复位力，以驱动限位部220靠近伸缩模组100，并与伸缩模组100配合。
由上可知，当伸缩模组100处于缩回状态时，限位部220处于限位位置，此时伸缩模组100与限位部220限位配合，弹性驱动件210因变形向伸缩模组100施加弹出力，但由于限位部220的限制，该弹出力不会发挥作用，伸缩模组100无法移动。如果伸缩模组100需要工作，磁性驱动部230向限位部220施加驱动力，使得限位部220沿远离伸缩模组100的方向运动，进而与伸缩模组100分离，最终到达释放位置。此时限位部220对于伸缩模组100的限制消失，弹性驱动件210向伸缩模组100施加的弹出力将会发挥作用，使得伸缩模组100移动至壳体之外。
伸缩模组100使用完毕之后，用户可以按压伸缩模组100，伸缩模组100 受到用户施加的按压力而移动至壳体内，并与联动复位件240接触，联动复位件240受力后转动，当联动复位件240与限位部220接触时，联动复位件240向限位部220施加复位力，使得限位部220在该复位力的作用下靠近伸缩模组100并与伸缩模组100限位配合，此时伸缩模组100重新回到前文所述的缩回状态。如此往复，就可以通过伸缩模组100移动而使伸缩模组100在工作状态和非工作状态之间切换，伸缩模组100不占用显示区域的面积，进而提高终端设备的屏占比。
本公开实施例中，伸缩模组100的伸缩移动无需电机以及结构较为复杂的传动机构，因此，本公开实施例公开的终端设备能解决相关技术中采用电机驱动伸缩模组100伸缩存在成本较高及结构较为复杂的问题。
上述限位部220具体可以包括主体部221以及设置于该主体部221的限位头222，该主体部221与磁性驱动部230相连。伸缩模组100具有限位凸台110，在限位位置，限位头222与限位凸台110配合以限制伸缩模组100移动。伸缩模组100设置限位凸台110后，限位部220和伸缩模组100运动时彼此不容易出现干涉，并且限位头222与限位凸台110更容易配合。
进一步地，限位头222具有第一限位平面222a。对应地，伸缩模组100的限位凸台110具有第二限位平面111，限位部220处于限位位置时，第一限位平面222a与第二限位平面110相贴合，且第一限位平面222a和第二限位平面110均垂直于伸缩模组100的移动方向(即开口的轴线方向)。这种结构下，第一限位平面222a与第二限位平面110之间的作用力可以最大程度地形成限制伸缩模组100的作用力，使得伸缩模组100更加可靠地保持在缩回状态。
限位部220与磁性驱动部230的连接关系可以有多种设置方式，例如，磁性驱动部230未产生磁力时，限位部220与磁性驱动部230之间有一定的距离，当磁性驱动部230产生磁力时，该磁力施加到限位部220上，使得限位部220靠近磁性驱动部230，进而远离伸缩模组100。但是，采用这种结构时，磁性驱动部230与限位部220之间的作用力不好把控，可能会导致限位部220无法快速远离伸缩模组100，甚至无法与伸缩模组100分离。鉴于此，可以在磁性驱动部230上设置凹陷部231，主体部221具有第一受力凸部223。 该第一受力凸部223的至少一部分位于磁性驱动部230的凹陷部231内，使得主体部221通过第一受力凸部223与磁性驱动部230相连。当磁性驱动部230产生磁力时，磁性驱动部230中形成该凹陷部231的部分将会移动，进而通过第一受力凸部223带动限位部220运动。
为了使联动复位件240更可靠、快速地驱动限位部220，主体部221还具有第二受力凸部224，联动复位件240可以通过该第二受力凸部224带动限位部220从释放位置向限位位置移动。当联动复位件240与伸缩模组100接触并被伸缩模组100驱动时，联动复位件240通过该第二受力凸部224驱动限位部220运动，使得限位部220靠近伸缩模组100并与伸缩模组100限位配合。
可选地，联动复位件240可以包括转动基体241以及分别设置于转动基体241的相对两侧的第一端部242和第二端部243。这里的第一端部242用于与伸缩模组100接触并承受伸缩模组100施加的力，第二端部243用于与第二受力凸部224背离伸缩模组100的一面接触，并通过第二受力凸部224驱动限位部220运动。即，伸缩模组100缩回壳体内时通过第一端部242带动联动复位件240转动，第二端部243通过第二受力凸部224带动限位部220从释放位置向限位位置移动。采用这种结构后，联动复位件240基本呈条形，其结构比较简单，且占用的空间更小，便于伸缩模组100、限位部220、磁性驱动部230和联动复位件240的布置。
上述第二端部243可以与转动基体241平齐，两者形成直杆状结构。但是，如果采用这种结构，第二受力凸部224与第二端部243之间的接触面积会比较小，不利于作用力的传递，并且也很容易在第二受力凸部224和第二端部243的表面形成划痕，对于伸缩模组100的精确伸缩产生负面影响。为了解决这一问题，第二端部243可以在转动基体241的径向方向上向外且向第二受力凸部224凸出。此时可以适当调整第二端部243的表面结构，使得第二端部243与第二受力凸部224之间的接触面积有所增大，继而解决前述问题。
如前所述，对于相互接触以传递作用力的部件来说，彼此接触时的面积大小将会影响作用力的传递效果和结构的完整性。基于此，本公开实施例中， 可以在第二受力凸部224上设置第一弧形受力面224a，在第二端部243上设置第一弧形施力面243a。第一弧形受力面224a与第一弧形施力面243a适配，以使第二端部243和第二受力凸部224相对可滑动，两者可以保持较大的接触面积，以此提升作用力传递的效果，同时保证结构的完整性。
与上述结构同理地，可以在伸缩模组100上设置第二弧形施力面120，第一端部242具有第二弧形受力面242a。第二弧形施力面120与第二弧形受力面242a适配，以使第一端部242和伸缩模组100相对可滑动，两者可以保持较大的接触面积，以此进一步提升作用力传递的效果，同时保证结构的完整性。
需要说明的是，上述的第一弧形受力面224a、第一弧形施力面243a、第二弧形受力面242a及第二弧形施力面120均是从主动施加作用力的角度进行命名，实际使用时，受力面也可能施力，施力面也可能受力，本文对此不做限制。
可选地，弹性驱动件210位于伸缩模组100的一侧，限位组件和联动复位件240均位于伸缩模组100的另一侧。如此设置后，弹性驱动件210的变形和复位基本不会受到限位部220、磁性驱动部230和联动复位件240的影响，同时限位部220、磁性驱动部230和联动复位件240之间的相互作用关系也不会受到弹性驱动件210的影响。并且，限位部220、磁性驱动部230和联动复位件240之间的相互作用比较密集，将三者设置到一起可以缩短动力的传递路径，以便于伸缩模组100快速响应用户的拍摄需求，以及快速回复至缩回状态。
本公开实施例所公开的终端设备可以为智能手机、笔记本电脑、平板电脑、电子书阅读器或可穿戴设备。当然，该终端设备也可以是其他设备，本公开实施例对此不做限制。
需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者用户设备不仅包括那些要素，而且还包括没有 明确列出的其他要素，或者是还包括为这种过程、方法、物品或者用户设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者用户设备中还存在另外的相同要素。
本公开上文实施例中重点描述的是各个实施例之间的不同，各个实施例之间不同的优化特征只要不矛盾，均可以组合形成更优的实施例，考虑到行文简洁，在此则不再赘述。
以上所述仅为本公开的实施例而已，并不用于限制本公开。对于本领域技术人员来说，本公开可以有各种更改和变化。凡在本公开的原理之内所作的任何修改、等同替换、改进等，均应包含在本公开的权利要求范围之内。
