结合图1至图3所示,本实施方式的可折叠电子设备10可以但不限于为手机、平板电脑等终端设备或者其它便携式电子设备。在本申请实施方式中,以手机为例进行说明。As shown in FIG. 1 to FIG. 3 , the foldable electronic device 10 of this embodiment may be, but not limited to, terminal devices such as mobile phones and tablet computers, or other portable electronic devices. In the implementation manner of this application, a mobile phone is taken as an example for description.
结合图1至图3所示,具体地,可折叠电子设备10包括壳组件100及柔性显示屏300。柔性显示屏300设置于壳组件100。柔性显示屏300具有用于进行显示的有效区域S,有效区域S包括第一平面区S1及与第一平面区S1连接的第二平面区S2,随着壳组件100在折叠状态与展开状态之间转换,柔性显示屏300具有内折状态(如图1所示)、展平状态(如图2所示)及外折状态(如图3所示),在内折状态、展平状态及外折状态下,第一平面区S1与第二平面区S2之间的夹角依次为0°、180°和360°。Referring to FIGS. 1 to 3 , specifically, the foldable electronic device 10 includes a case assembly 100 and a flexible display 300 . The flexible display 300 is disposed on the case assembly 100 . The flexible display screen 300 has an active area S for displaying. The active area S includes a first plane area S1 and a second plane area S2 connected to the first plane area S1. The flexible display screen 300 has an inwardly folded state (as shown in FIG. 1 ), a flattened state (as shown in FIG. 2 ) and an outwardly folded state (as shown in FIG. 3 ). In the outwardly folded state, the included angles between the first planar area S1 and the second planar area S2 are 0°, 180° and 360° in sequence.
可以理解,壳组件100包括第一壳体110及与第一壳体110连接的第二壳体130,第一壳体110与第二壳体130呈中空结构,以内置可供柔性显示屏300进行显示的相关电子元器件。至少部分第一壳体110被柔性显示屏300覆盖,至少部分第二壳体130被柔性显示屏300覆盖,即第一壳体110及第二壳体130均与柔性显示屏300直接或间接连接,并共同对柔性显示屏300起到支撑作用。It can be understood that the shell assembly 100 includes a first shell 110 and a second shell 130 connected to the first shell 110 , the first shell 110 and the second shell 130 are hollow structures for built-in flexible display screen 300 Associated electronic components for display. At least part of the first housing 110 is covered by the flexible display 300, and at least part of the second housing 130 is covered by the flexible display 300, that is, both the first housing 110 and the second housing 130 are directly or indirectly connected to the flexible display 300 , and jointly play a supporting role for the flexible display screen 300 .
可以理解,柔性显示屏300中能够进行显示的区域为有效区域S。为使有效区域S较好的进行显示,第一壳体110可提供呈平面的第一安装面(未示出),第二壳体130可提供呈平面的第二安装面(未示出),在柔性显示屏300连接于第一壳体110与第二壳体130后,对应于第一安装面的部分柔性显示屏300紧靠第一安装面而成为平面的第一平面区S1,对应与第二安装面的部分柔性显示屏300紧靠第二安装面而成为平面的第二平面区S2。另外,在柔性显示屏300在内折状态、展平状态及外折状态之间改变时,第一平面区S1与第二平面区S2均呈平面而不会被折弯。It can be understood that the area capable of displaying in the flexible display screen 300 is the effective area S. In order to better display the effective area S, the first housing 110 may provide a first flat mounting surface (not shown), and the second housing 130 may provide a second flat mounting surface (not shown) After the flexible display screen 300 is connected to the first housing 110 and the second housing 130, the part of the flexible display screen 300 corresponding to the first installation surface is close to the first installation surface and becomes a first planar region S1 of a plane, corresponding to The part of the flexible display screen 300 on the second installation surface is close to the second installation surface to form a second planar region S2 that is planar. In addition, when the flexible display 300 changes between the inwardly folded state, the flattened state and the outwardly folded state, both the first planar area S1 and the second planar area S2 are planar and will not be bent.
可以理解,在柔性显示屏300处于内折状态时,第一平面区S1与第二平面区S2相贴合,且两者之间的夹角为0°,此时,有效区域S被第一壳体110与第二壳体130夹紧,即有效区域S位于第一壳体110与第二壳体130之间而无法外露,因而无法进行显示,但第一壳体110与第二壳体130可以对有效区域S进行保护,避免有效区域S被损伤。在柔性显示屏300处于展平状态时,整个有效区域S被展平,从而使第一平面区S1与第二平面区S2共面而两者夹角达到180°,此时,有效区域S的全部都可进行显示而使可折叠电子设备10具有最大的显示面积,从而实现大屏显示。在柔性显示屏300处于外折状态时,第一平面区S1与第二平面区S2之间的夹角为360°,且两者相对间隔,而第一壳体110与第二壳体130位于第一平面区S1域第二平面区S2之间。此时,第一平面区S1与第二平面区S2可各自分别进行显示,使得可折叠电子设备10实现半屏显示。It can be understood that when the flexible display screen 300 is in the folded state, the first planar area S1 and the second planar area S2 are in contact with each other, and the angle between them is 0°. At this time, the effective area S is covered by the first The casing 110 and the second casing 130 are clamped, that is, the effective area S is located between the first casing 110 and the second casing 130 and cannot be exposed, so it cannot be displayed, but the first casing 110 and the second casing 130 can protect the active area S to prevent the active area S from being damaged. When the flexible display screen 300 is in the flattened state, the entire effective area S is flattened, so that the first plane area S1 and the second plane area S2 are coplanar and the angle between them reaches 180°. At this time, the effective area S All of them can be displayed so that the foldable electronic device 10 has the largest display area, thereby realizing a large-screen display.

During the state transition of the flexible display screen 300, the first planar area S1 and/or the second planar area S2 move relative to the shell assembly 100 to adapt to the shape change of the shell assembly 100, thereby ensuring flexibility in the flattened state and the outwardly folded state.

具体地,可以使柔性显示屏300的一端与第一壳体110固定连接,而使其另一端相对第二壳体130可活动,此时,在柔性显示屏300状态转变的过程中,柔性显示屏300的第二平面区S2相对第二壳体130运动,以在展平状态与外折状态张紧柔性显示屏300。或者,也可以使柔性显示屏300的一端与第二壳体130固定连接,而使其另一端相对第一壳体110可活动,此时,在柔性显示屏300状态转变的过程中,柔性显示屏300的第一平面区S1相对第一壳体110运动,以在展平状态与外折状态张紧柔性显示屏300。在本申请实施例中,柔性显示屏300的一端相对第一壳体110活动,柔性显示屏300的另一端相对第二壳体130活动,如此,就使得柔性显示屏300的第一平面区S1相对第一壳体110、第二平面区S2相对第二壳体130均能够运动,以能够在展平状态与外折状态张紧柔性显示屏300。Specifically, one end of the flexible display 300 can be fixedly connected to the first casing 110, and the other end can be moved relative to the second casing 130. At this time, during the state transition of the flexible display 300, the flexible display The second plane area S2 of the screen 300 moves relative to the second casing 130 to tension the flexible display screen 300 in the flattened state and the outwardly folded state. Alternatively, one end of the flexible display screen 300 may be fixedly connected to the second housing 130, and the other end may be movable relative to the first housing 110.

In this way, by changing the area of the effective area S as the state of the flexible display 300 changes, it can be ensured that the effective area S can just cover the first installation surface, the second installation surface and the area between them, thereby It can maintain normal display in various states, avoiding the problem that the effective area S is redundant or is pulled by transition and affects the normal display.

It can be understood that the sensor 820 can send the detected angle information between the first plane area S1 and the second plane area S2 to the circuit board 810, and the circuit board 810 then sends a signal to the screen adjustment assembly 500, so that the screen adjustment assembly 500 drives the flexible The display screen 300 moves, so that the area of the effective area S changes as the state of the flexible display screen 300 changes. Specifically, the sensor 820 can periodically send included angle information to the circuit board 810 , and the circuit board 810 can determine the change trend and speed of the included angle through a plurality of included angle information. Further, the sensor 820 is a Hall sensor, and may also be other sensors 820 with similar functions.

The included angle α is 0°, that is, the sensor 820 is at the initial position in the inwardly folded state. For the included angle data α sent by the sensor 820, the circuit board 810 first determines the change trend of α, and if α is gradually increasing, it is judged that the flexible display screen 300 needs to be converted from the inwardly folded state to the flattened state or from the flattened state. When the state is turned outward, the area of the effective area S needs to be increased, so a signal is sent to the servo motor to make the servo motor rotate forward, and the servo motor further drives the first rotor 520 to rotate forward to release the flexible display 300; if α is If the trend is gradually decreasing, it is judged that the flexible display screen 300 needs to switch from the outwardly folded state to the flattened state or from the flattened state to the inwardly folded state, then the area of the effective area S needs to be reduced, so a signal is sent to the servo motor so that The servo motor reverses, and the servo motor further drives the first rotor 520 to rotate in reverse to wind up the flexible display screen 300 . In addition, by judging the relationship between α and 180°, it can be determined that the flexible display screen 300 specifically transitions from the inward-folded state to the flattened state, from the flattened state to the outward-folded state, from the outward-folded state to the flattened state, and from the folded state to the flattened state. One of the transitions from the flattened state to the folded state. In addition, the forward or reverse rotation speed of the servo motor can be controlled by changing the speed of the included angle, so as to avoid redundant or excessive pulling of the flexible display screen 300 .

具体地,缓冲层330在与其所在平面平行的方向的弹性变形能力小于在与其所在平面相垂直的方向的弹性变形能力。可以理解,缓冲层330在与其所在平面平行的方向的弹性变形能力小且弹性模量高,因而不容易发生变形,从而避免在屏幕调节组件500带动柔性显示屏300相对壳组件100运动时发生伸缩,即尽可能维持柔性显示屏300沿其长度方向及宽度方向的尺寸不改变。而缓冲层330在与其所在平面垂直的方向的弹性变形能力较强,即具有较大的变形能力而能够起到缓冲作用,从而不仅可以吸收功能层320内侧不平整的结构特征,提高功能层320的平整程度,而且还可以在弯折区S3弯折的过程中释放部分应力,通过缓冲层330的变形来吸收不同形态下相邻两个第二支撑块630之间间隙的变化对功能层320的影响,提高柔性显示屏300的使用寿命。具体地,缓冲层330可以为缓冲泡棉或TPU(Thermoplastic polyurethanes)。可以理解,在展平状态下,第一抵持部631与第二抵持部632相抵持,而在向外折状态转换的过程中,相邻两个第二支撑块630将在力的作用下强制变形,并在靠近柔性显示屏300的一侧形成间隙,直至达到第三抵持部635与第四抵持部636相抵持的状态,此过程中,通过缓冲层330的变形可以吸收相邻两个第二支撑块630之间间隙的变化对功能层320的影响。Specifically, the elastic deformation capacity of the buffer layer 330 in a direction parallel to its plane is smaller than that in a direction perpendicular to its plane. It can be understood that the buffer layer 330 has a small elastic deformation capability and a high elastic modulus in a direction parallel to its plane, so it is not easy to deform, thereby avoiding expansion and contraction when the screen adjustment assembly 500 drives the flexible display screen 300 to move relative to the shell assembly 100 , that is, keep the dimensions of the flexible display 300 along its lengthwise and widthwise directions unchanged as much as possible. The buffer layer 330 has a strong elastic deformation capacity in the direction perpendicular to the plane where it is located, that is, it has a large deformation capacity and can play a buffering role, so that it can not only absorb the uneven structural features of the functional layer 320 inside, but also improve the performance of the functional layer 320. The degree of flatness, but also part of the stress can be released during the bending process of the bending area S3, and the deformation of the buffer layer 330 can absorb the change of the gap between two adjacent second support blocks 630 in different forms. influence, and improve the service life of the flexible display 300. Specifically, the buffer layer 330 can be buffer foam or TPU (Thermoplastic polyurethanes). It can be understood that in the flattened state, the first abutting portion 631 is abutted against the second abutting portion 632, while in the process of transitioning to the outwardly folded state, the two adjacent second support blocks 630 will be under the action of force. and a gap is formed on the side close to the flexible display 300 until the third abutting portion 635 and the fourth abutting portion 636 are abutted against each other. During this process, the deformation of the buffer layer 330 can absorb the corresponding The effect of the change of the gap between two adjacent second support blocks 630 on the functional layer 320 .

考虑到第二壳体130与传动机构700的连接方式、第一壳体110与传动机构700的连接方式一致,下面仅对第一壳体110与传动机构700的连接方式进行详细介绍。Considering the connection between the second housing 130 and the transmission mechanism 700 and the connection between the first housing 110 and the transmission mechanism 700 are consistent, only the connection between the first housing 110 and the transmission mechanism 700 will be described in detail below.
如图11所示,为传动机构700与第一壳体110的连接关系简图。结合图10与图11所示,第一连杆721与挡盖710的转动连接构成转动副B,第二连杆722与挡盖710的转动连接构成转动副A,第一连杆721与第一连接部113的转动连接构成转动副C,第二连杆722与第二连接部114的滑动连接构成滑动副D,设定位于挡盖710的A和B为固定端,则C和D为移动端,第一连杆721与第二连杆722的形状不作限制,只需要在柔性显示屏300在内折状态与外折状态之间转换的过程中,第一连杆721与第二连杆722互不干涉且强度可靠即可,挡盖710对第一连杆721与第二连杆722不构成干涉。可以理解,滑动副D限制第一壳体110的旋转角度,使得第一壳体110相对挡盖710的旋转角度与滑动副D的旋转角度相同。旋转副C限制第一壳体110转动过程中与挡盖710的距离,即第一壳体110上点位C与挡盖710上的点位B之间的距离恒定。如此,就使得第一壳体110相对挡盖710的运动轨迹得以限定,同样的,第三连杆731、第四连杆732与第二壳体130的连接方式,可以使得第二壳体130相对挡盖710的运动轨迹得以限定,进而使得第一壳体110与第二壳体130沿既定轨迹相对旋转。As shown in FIG. 11 , it is a schematic diagram of the connection relationship between the transmission mechanism 700 and the first housing 110 .
