在本发明实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本发明实施例和所附权利要求书中所使用的单数形式的 "一种" 、 "所述" 和 "该" 也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语 "和 /或" 是指并包含一个或多个相关联的列出项目的任何或所有可能组合。实施例一 The terms used in the embodiments of the present invention are for the purpose of describing particular embodiments only, and are not intended to limit the invention. The singular forms "a", "the" and "the" It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items. Embodiment 1

图 1为本发明实施例一提供的折叠式移动终端的分解结构示意图，图 2为图 1 is a schematic exploded view of a folding mobile terminal according to Embodiment 1 of the present invention, and FIG. 2 is a schematic diagram of FIG.

1所示折叠式移动终端折叠后的结构示意图，图 3为图 1所示折叠式移动终端展开后的结构示意图。结合图 1至图 3所示的内容，该折叠式移动终端包括：第一结构件 1、第二结构件 2、转轴 3以及主板（图中未示出）。其中，第一结构件 1 通过转轴 3与第二结构件 2相连接，第一结构件 1围绕转轴 3相对于第二结构件 2 转动。主板可以内置于第一结构件 1和 /或第二结构件 2 , 此处不做限定，在第一结构件 1的内侧表面以及第二结构件 2的内侧表面上设置有内显示屏 4。第一结构件 1的外侧表面设置有外显示屏 5 ,内显示屏 4与外显示屏 5均通过柔性电路板 6与主板相连。 1 is a schematic structural view of the folding mobile terminal after folding, and FIG. 3 is a schematic structural view of the folding mobile terminal shown in FIG. Referring to the contents shown in FIG. 1 to FIG. 3, the folding mobile terminal comprises: a first structural member 1, a second structural member 2, a rotating shaft 3, and a main board (not shown). The first structural member 1 is coupled to the second structural member 2 via a rotating shaft 3, and the first structural member 1 is rotated about the rotating shaft 3 relative to the second structural member 2. The main board may be built in the first structural member 1 and/or the second structural member 2, which is not limited herein, and an inner display screen 4 is provided on the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2. The outer surface of the first structural member 1 is provided with an outer display 5, and both the inner display 4 and the outer display 5 are connected to the main board via the flexible circuit board 6.

通常情况下，内显示屏 4的面积会被设计为大于外显示屏 5的面积。这种情况下，通过外显示屏 5与内显示屏 4之间切换显示，来实现显示屏大小的转换，使得该折叠式移动终端兼具手机和平板电脑的功能，方便携带，接打电话方便操作。 Typically, the area of the inner display 4 will be designed to be larger than the area of the outer display 5. This kind of situation In this case, the display screen is switched between the external display 5 and the internal display 4 to realize the conversion of the display size, so that the folding mobile terminal has the functions of a mobile phone and a tablet computer, is convenient to carry, and is convenient to operate by taking a call.

本实施例一中所说的内侧表面以及外侧表面是一个相对的概念，由于实施例一中提供的是一种折叠式移动终端，那么，按照本领域技术人员甚至是一般消费者的理解，内侧表面即为折叠后不外露的表面，而外侧表面即为折叠后仍然外露的表面。以最常见的笔记本电脑为例，合上笔记本电脑之后，使用者可以看到的外壳部分可以理解为外侧表面，看不到的键盘、屏幕等可以理解为内侧表面。参见图 1中关于第一结构件 1的外侧表面以及第二结构件 2的外侧表面的箭头指示，以及图 3中关于第一结构件 1的内侧表面以及第二结构件 2的内侧表面的箭头指示。 The inner side surface and the outer side surface referred to in the first embodiment are a relative concept. Since a folding type mobile terminal is provided in the first embodiment, the inner side is understood by those skilled in the art and even the general consumer. The surface is the surface that is not exposed after folding, and the outer surface is the surface that is still exposed after folding. Taking the most common notebook computer as an example, after closing the notebook computer, the outer casing portion that the user can see can be understood as the outer side surface, and the invisible keyboard, screen, etc. can be understood as the inner side surface. Referring to the arrow indications in FIG. 1 regarding the outer side surface of the first structural member 1 and the outer side surface of the second structural member 2, and the arrows in FIG. 3 regarding the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 Instructions.

在本发明提供的后续实施例中，内显示屏 4可以是一整块屏幕，例如，能够折叠显示图像的柔性显示屏。这里所说的柔性显示屏使用了 PHOLED磷光性 OLED技术，具有低功耗，直接可视柔性面板，由柔软的材料制成，可变型可弯曲的显示装置。柔性显示屏可以是触摸式的，与现有的触摸显示屏实现相同的功能；也可以为了更好地保护自身而做出非触摸式的，仅作为显示装置使用。 In a subsequent embodiment provided by the present invention, the inner display 4 may be a one-piece screen, for example, a flexible display capable of folding an image for display. The flexible display used here uses PHOLED phosphorescent OLED technology, which has low power consumption, direct visible flexible panel, made of soft material, and variable and flexible display device. The flexible display can be touch-enabled, performing the same function as the existing touch display; it can also be made non-touch for better protection of itself, and is only used as a display device.

在本发明提供的后续实施例中，内显示屏 4还可以是多块屏幕拼接的分体显示器。例如，由设置在第一结构件 1的内侧表面的第一显示屏以及设置在第二结构件 2的内侧表面的第二显示屏拼接而成。这里不限制组成第一显示屏以及第二显示屏的屏幕数目，第一显示屏或者第二显示屏既可以是自成一块屏幕，也可以是由多块小屏幕拼接而成的。实施例二 In a subsequent embodiment provided by the present invention, the internal display 4 may also be a split display of a plurality of screen splicing.

The radio part is responsible for transmitting and receiving signals to communicate with the outside world, including antenna and controller frequency synthesis and power amplifiers for modulation and demodulation. The logic part consists of a CPU and software memory, etc., and is responsible for some conventional operations, including controlling the operation of various parts of the entire mobile terminal. The power supply part is composed of a power supply integrated circuit (IC) and a power supply tube, and distributes the power of the battery to each component to ensure that each component works normally. The interface part is responsible for the operation and communication between the user, such as the display screen, the Subscriber Identity Module (SIMr), the vibrator, the ringer, the keyboard, the indicator light, and so on. Of course, the motherboard provided by the embodiment of the present invention may further include components that are commonly used in mobile terminals such as peripheral circuits, interfaces, slots, and the like, and are not mentioned herein. The working principle of the folding mobile terminal provided by the embodiment of the present invention is the same as that of the mobile terminal provided in the prior art, and will not be described here.

与现有技术中提供的移动终端的不同之处在于：本发明提供的折叠式移动终端的主板可以监控第一结构件 1的内侧表面与第二结构件 2的内侧表面之间的夹角。当夹角处于第一预设范围的时候，主板可以仅对外显示屏 5进行信号供应，当夹角处于第二预设范围的时候，主板可以仅对内显示屏 4进行信号供应，如果内显示屏 4为非触摸屏，还可以将外显示屏 5转换为触摸板，实现内显示屏 4上鼠标的移动、点击等鼠标触发功能。或者，当夹角处于第二预设范围的时候，主板可以对内显示屏 4和外显示屏 5均进行信号供应。这里所说的第一预设范围和第二预设范围可以是预先设置好输入到主板中的数值，当然也可以在折叠式移动终端的使用过程中由用户进行个性化的设定。优选的，第一预设范围的最低值可以为 0度，也即第一结构件 1的内侧表面与第二结构件 2的内侧表面彼此贴合的情况；最高值不超过 360度。一般情况下会设置一个较小值，如 10度、 20度等等。第二预设范围的最高值不超过 360度，当然，最优选的是 180度，也即第一结构件 1的内侧表面与第二结构件 2的内侧表面形成一个展开的屏幕的情况；最小值一般优选与第一预设范围的最大值相同或相邻近。 The difference from the mobile terminal provided in the prior art is that the main board of the folding mobile terminal provided by the present invention can monitor the angle between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2. When the angle is in the first preset range, the main board can only supply signals to the external display 5, and when the angle is in the second preset range, the main board can only supply signals to the internal display 4, if the internal display The screen 4 is a non-touch screen, and the external display screen 5 can also be converted into a touch panel, and the mouse trigger function such as movement, clicking, and the like of the mouse on the internal display screen 4 is realized. Alternatively, the motherboard can supply signals to both the internal display 4 and the external display 5 when the included angle is in the second predetermined range. The first preset range and the second preset range mentioned herein may be preset values input to the main board, and may of course be personalized by the user during use of the foldable mobile terminal. Preferably, the lowest value of the first predetermined range may be 0 degrees, that is, the inner surface of the first structural member 1 and the inner side surface of the second structural member 2 are attached to each other; the highest value does not exceed 360 degrees. In general, a smaller value, such as 10 degrees, 20 degrees, etc., is set. The highest value of the second predetermined range does not exceed 360 degrees, and of course, most preferably 180 degrees, that is, the case where the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 form an unfolded screen; The value is generally preferably the same as or adjacent to the maximum of the first predetermined range.

具体的，主板可以但不限于通过如下方式监控第一结构件 1的内侧表面以及第二结构件 2的内侧表面之间的夹角： Specifically, the main board can be, but is not limited to, monitoring the angle between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 by:

在第一结构件 1上设置第一加速传感器，在第二结构件 2上设置第二加速传感器，通过第一加速传感器测量第一结构件 1与地面的夹角，通过第二加速传感器测量第二结构件 2与地面的夹角，并通过计算上述两个夹角之间的差值来获得第一结构件 1的内侧表面与第二结构件 2的内侧表面之间的夹角。 A first acceleration sensor is disposed on the first structural member 1, a second acceleration sensor is disposed on the second structural member 2, an angle between the first structural member 1 and the ground is measured by the first acceleration sensor, and the second acceleration sensor is used to measure the angle The angle between the two structural members 2 and the ground, and the angle between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 is obtained by calculating the difference between the two included angles.

或者，主板还可以通过如下方式来监控第一结构件 1的内侧表面以及第二结构件 2的内侧表面之间的夹角：在第二结构件 2的内侧表面设置一可伸缩的触发件，该触发件在第一结构件 1的内侧表面与第二结构件 2的内侧表面之间的夹角为 0。时可以完全缩进第二结构件 2内，在夹角大于等于第一预设范围的最大值时，该触发件不与第一结构件 1发生接触。由此，一旦该触发件与第一结构件 1的内侧表面相接触，也即该触发件被触发，说明第一结构件 1的内侧表面与第二结构件 2的内侧表面之间的夹角处于第一预设范围内。如果该触发件不与第一结构件 1的内侧表面相接触，也即该触发件不被触发，说明第一结构件 1 的内侧表面与第二结构件 2的内侧表面之间的夹角处于第二预设范围内。 Alternatively, the main board can also monitor the angle between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 by providing a retractable trigger member on the inner side surface of the second structural member 2, a clamping member between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 The angle is 0. The second structural member 2 can be completely retracted, and the trigger member does not come into contact with the first structural member 1 when the angle is greater than or equal to the maximum value of the first predetermined range. Thus, once the trigger member is in contact with the inner side surface of the first structural member 1, that is, the trigger member is triggered, the angle between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 is illustrated. In the first preset range. If the trigger member does not contact the inner side surface of the first structural member 1, that is, the trigger member is not triggered, the angle between the inner side surface of the first structural member 1 and the inner side surface of the second structural member 2 is Within the second preset range.

在上述实施例中提到，如果内显示屏 4为非触摸屏，还可以将外显示屏 5 转换为触摸板，实现内显示屏 4上鼠标的移动、点击等鼠标触发功能。将外显示屏 5转换为触摸板的实现方式可以为：主机发送控制信号，关闭外显示屏 5 的显示，但仍然接收外显示屏 5的信号输入，这样，外显示屏 5即可以实现触摸板的功能。 It is mentioned in the above embodiment that if the internal display 4 is a non-touch screen, the external display 5 can also be converted into a touch panel, and the mouse trigger function such as movement, clicking, and the like of the mouse on the internal display 4 can be realized. The implementation of converting the external display 5 into the touch panel may be: the host sends a control signal to turn off the display of the external display 5, but still receives the signal input of the external display 5, so that the external display 5 can implement the touch panel. The function.

在上述实施例中还提到，主板可以对内显示屏 4和外显示屏 5均进行信号供应。这时，本发明实施例提供的第二结构件 2的外侧表面上还可以设置有物理按键。该物理按键可以是 qwerty形式的键盘，也可以是九宫格形式的键盘，本发明不做具体限定。这种情况下，本发明实施例提供的折叠式移动终端便可以被理解为两个互不干涉的物理实体，内显示屏 4可以实现平板电脑的显示和信号输入，而外显示屏 5和物理按键可以实现手机的显示和信号输入。这样，可以由至少两个用户同时使用该折叠式移动终端，互不干涉。实施例三 It is also mentioned in the above embodiment that the main board can supply signals to both the internal display 4 and the external display 5. At this time, the outer surface of the second structural member 2 provided by the embodiment of the present invention may further be provided with a physical button. The physical button may be a keyboard in the form of qwerty or a keyboard in the form of a nine-square grid, which is not specifically limited in the present invention. In this case, the foldable mobile terminal provided by the embodiment of the present invention can be understood as two physical entities that do not interfere with each other, and the internal display screen 4 can realize display and signal input of the tablet computer, and the external display screen 5 and the physical The buttons can be used to display and input signals from the phone. Thus, the foldable mobile terminal can be used simultaneously by at least two users without mutual interference. Embodiment 3

The radio part is responsible for transmitting and receiving signals to communicate with the outside world, including antenna and controller frequency synthesis and power amplifiers for modulation and demodulation. The logic part consists of a CPU and software memory, etc., and is responsible for some conventional operations, including controlling the operation of various parts of the entire mobile terminal. The power supply part is composed of a power IC and a power supply tube, and the power of the battery is distributed to each component to ensure that each component works normally. The interface part is responsible for the operation and communication between the user, such as the display screen, SIM card, vibrator, ringing, keyboard, indicator light and so on.
