Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and/or letters in different examples.

In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and/or the use of other materials.
下面参考附图描述根据本发明实施例的柔性铰链1。柔性铰链1可以用于显示装置100，显示装置100包括柔性显示模块2，柔性铰链1与柔性显示模块2连接可以实现柔性显示模块2在折叠位置和展开位置之间运动。例如，在本发明的一个具体地示例中，柔性显示模块2为OLED显示屏，其中，OLED的中文名称为有机发光二极管，英文全称为：Organic Light-Emitting Diode。The flexible hinge 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The flexible hinge 1 can be used in a display device 100, and the display device 100 includes a flexible display module 2. The flexible hinge 1 is connected to the flexible display module 2 to enable the flexible display module 2 to move between a folded position and an unfolded position. For example, in a specific example of the present invention, the flexible display module 2 is an OLED display screen, wherein the Chinese name of OLED is organic light-emitting diode, and the full English name is: Organic Light-Emitting Diode.
如图1所示，根据本发明实施例的柔性铰链1，包括：连杆11和弹性件12。可以理解的是，连杆11作为固定轴，弹性件12作为转动部，弹性件12可以相对连杆11转动，而且在转动的过程中，弹性件12可以相对固定部移动并产生形变。利用弹性件12分别与柔性显示模块2的第二方向相对的两侧连接，在柔性显示模块2进行折叠或展开时，弹性件12可以以连杆11为旋转中心发生弹性变形，由此仅需要设置连杆11和弹性件12便可以实现柔性显示模块2的折叠和展开，从而可以减少柔性铰链1的零件数量，同时还可以简化结构的复杂度。As shown in FIG1 , the flexible hinge 1 according to an embodiment of the present invention includes: a connecting rod 11 and an elastic member 12. It can be understood that the connecting rod 11 serves as a fixed axis, and the elastic member 12 serves as a rotating part. The elastic member 12 can rotate relative to the connecting rod 11, and during the rotation, the elastic member 12 can move relative to the fixed part and deform. The elastic member 12 is connected to the two sides of the flexible display module 2 opposite to each other in the second direction. When the flexible display module 2 is folded or unfolded, the elastic member 12 can be elastically deformed with the connecting rod 11 as the rotation center. Therefore, only the connecting rod 11 and the elastic member 12 need to be provided to realize the folding and unfolding of the flexible display module 2, thereby reducing the number of parts of the flexible hinge 1 and simplifying the complexity of the structure.
如图1和图2所示，连杆11沿柔性显示模块2的第一方向延伸，连杆11的横截面形成为弧形。可以理解的是，柔性显示模块2因为是柔性件，柔性显示模块2本身可以轻易的发生形变，通过将连杆11的横截面设置成弧形，弧形结构可以对柔性显示模块2进行支撑，使得柔性显示模块2在展开时，显示区域较为平整，从而提升用户的使用体验。具体地，在本发明的一个示例中，连杆11朝向靠近柔性显示模块2的一侧凸出。As shown in FIG. 1 and FIG. 2 , the connecting rod 11 extends along the first direction of the flexible display module 2, and the cross section of the connecting rod 11 is formed into an arc shape. It can be understood that because the flexible display module 2 is a flexible member, the flexible display module 2 itself can be easily deformed. By setting the cross section of the connecting rod 11 to an arc shape, the arc structure can support the flexible display module 2, so that when the flexible display module 2 is unfolded, the display area is relatively flat, thereby improving the user experience. Specifically, in one example of the present invention, the connecting rod 11 protrudes toward the side close to the flexible display module 2.
如图2-图4所示，弹性件12包括：支撑部121、两个第一弯折部122、两个第二弯折部123和两个连接部124，支撑部121与连杆11连接。可以理解的是，支撑部121与连杆11连接，由此可以将弹性件12固定在连杆11上，而且，支撑部121的横截面的外轮廓与连杆11的横截面的内轮廓匹配。也就是说，支撑部121的横截面的外轮廓同样为弧形，通过将支撑部121的横截面的外轮廓设置成弧形，弧形结构可以对柔性显示模块2进行支撑，使得柔性显示模块2在展开时，显示区域较为平整，从而提升用户的使用体验。As shown in Figures 2 to 4, the elastic member 12 includes: a support portion 121, two first bending portions 122, two second bending portions 123 and two connecting portions 124, and the support portion 121 is connected to the connecting rod 11. It can be understood that the support portion 121 is connected to the connecting rod 11, thereby fixing the elastic member 12 on the connecting rod 11, and the outer contour of the cross section of the support portion 121 matches the inner contour of the cross section of the connecting rod 11. In other words, the outer contour of the cross section of the support portion 121 is also arc-shaped. By setting the outer contour of the cross section of the support portion 121 to an arc, the arc structure can support the flexible display module 2, so that when the flexible display module 2 is unfolded, the display area is relatively flat, thereby improving the user experience.
如图2和图3所示，两个第一弯折部122分别与支撑部121的两端连接，且第一弯折部122的凸出方向与支撑部121的凸出方向相反。可以理解的是，通过在支撑部121的两端分别设置第一弯折部122，且第一弯折部122的凸出方向与支撑部121的凸出方向相反，由此可以提升弹性件12的弹性强度，使得弹性件12在跟随柔性显示模块2折叠或压缩的过程中，第一弯折部122可以为柔性显示模块2提供良好的弹性力。As shown in FIG. 2 and FIG. 3 , the two first bending portions 122 are respectively connected to the two ends of the support portion 121, and the protruding direction of the first bending portion 122 is opposite to the protruding direction of the support portion 121. It can be understood that by respectively providing the first bending portions 122 at the two ends of the support portion 121, and the protruding direction of the first bending portions 122 is opposite to the protruding direction of the support portion 121, the elastic strength of the elastic member 12 can be improved, so that when the elastic member 12 follows the folding or compression of the flexible display module 2, the first bending portion 122 can provide good elastic force for the flexible display module 2.
如图2和图3所示，两个第二弯折部123分别与两个第一弯折部122的背离支撑部121的一端连接，且第二弯折部123的凸出方向与支撑部121的凸出方向相同。可以理解的是，通过在第一弯折部122的背离支撑部121的两端分别设置一个第二弯折部123，且第二弯折部123的凸出方向与第一弯折部122的凸出方向相反，由此可以进一步提升弹性件12的弹性强度，从而更好的为柔性显示模块2提供良好的弹性力，同时弹性件12在跟随柔性显示模块2折叠或压缩的过程中，第二弯折部123还可以分担第一弯折部122的弹性力，避免第一弯折部122的受力集中。As shown in FIG. 2 and FIG. 3 , the two second bending portions 123 are respectively connected to one end of the two first bending portions 122 away from the supporting portion 121, and the protruding direction of the second bending portion 123 is the same as the protruding direction of the supporting portion 121. It can be understood that by respectively arranging a second bending portion 123 at both ends of the first bending portion 122 away from the supporting portion 121, and the protruding direction of the second bending portion 123 is opposite to the protruding direction of the first bending portion 122, the elastic strength of the elastic member 12 can be further improved, thereby better providing good elastic force for the flexible display module 2, and at the same time, when the elastic member 12 follows the folding or compression of the flexible display module 2, the second bending portion 123 can also share the elastic force of the first bending portion 122, thereby avoiding the force concentration of the first bending portion 122.
如图2和图3所示，两个连接部124的一端分别与两个第二弯折部123的背离第一弯折部122的一端连接，两个连接部124的另一端分别与柔性显示模块2的第二方向的两侧连接，其中，第二方向与第一方向垂直。可以理解的是，连接部124可以实现弹性件12与柔性显示模块2之间的连接，在柔性显示模块2折叠或展开的过程中，连接部124可以跟随柔性显示模块2移动，同时带动第二弯折部123、第一弯折部122相对支撑部121产生弹性形变。其中，第一方向可以为柔性显示模块2的长度方向，第二方向为柔性显示模块2的宽度方向；或者，第二方向可以为柔性显示模块2的长度方向，第一方向为柔性显示模块2的宽度方向。As shown in FIG. 2 and FIG. 3 , one end of the two connecting portions 124 is respectively connected to one end of the two second bending portions 123 away from the first bending portion 122, and the other ends of the two connecting portions 124 are respectively connected to the two sides of the second direction of the flexible display module 2, wherein the second direction is perpendicular to the first direction. It can be understood that the connecting portion 124 can realize the connection between the elastic member 12 and the flexible display module 2, and during the folding or unfolding of the flexible display module 2, the connecting portion 124 can move with the flexible display module 2, and at the same time drive the second bending portion 123 and the first bending portion 122 to produce elastic deformation relative to the supporting portion 121. Among them, the first direction can be the length direction of the flexible display module 2, and the second direction is the width direction of the flexible display module 2; or, the second direction can be the length direction of the flexible display module 2, and the first direction is the width direction of the flexible display module 2.
需要说明的是，第一弯折部122的凸出方向与支撑部121的凸出方向相反，第二弯折部123的凸出方向与支撑部121的凸出方向相同，上述描述的是柔性显示模块2在展开状态下柔性铰链1的结构。It should be noted that the protruding direction of the first bending portion 122 is opposite to the protruding direction of the supporting portion 121, and the protruding direction of the second bending portion 123 is the same as the protruding direction of the supporting portion 121. The above description is the structure of the flexible hinge 1 when the flexible display module 2 is in the unfolded state.
具体地，在本发明的一个示例中，支撑部121、两个第一弯折部122、两个第二弯折部123和两个连接部124为一体成型件。由此，一体成型的结构不仅可以保证支撑部121、两个第一弯折部122、两个第二弯折部123和两个连接部124的结构、性能稳定性，并且方便成型、制造简单，而且省去了多余的装配件以及连接工序，大大提高了支撑部121、两个第一弯折部122、两个第二弯折部123和两个连接部124的装配效率，保证了支撑部121、两个第一弯折部122、两个第二弯折部123和两个连接部124的连接可靠性，再者，一体成型的结构的整体强度和稳定性较高，组装更方便，寿命更长。Specifically, in one example of the present invention, the support portion 121, the two first bends 122, the two second bends 123 and the two connecting portions 124 are an integrally formed part. Thus, the integrally formed structure can not only ensure the structural and performance stability of the support portion 121, the two first bends 122, the two second bends 123 and the two connecting portions 124, but also facilitates molding and is simple to manufacture, and eliminates redundant assembly parts and connection processes, greatly improving the assembly efficiency of the support portion 121, the two first bends 122, the two second bends 123 and the two connecting portions 124, ensuring the connection reliability of the support portion 121, the two first bends 122, the two second bends 123 and the two connecting portions 124, and further, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.
根据本发明实施例的柔性铰链1，柔性铰链1包括：连杆11和弹性件12，利用弹性件12分别与柔性显示模块2的第二方向相对的两侧连接，在柔性显示模块2进行折叠或展开时，弹性件12可以以连杆11为旋转中心发生弹性变形，由此仅需要设置连杆11和弹性件12便可以实现柔性显示模块2的折叠和展开，从而可以减少柔性铰链1的零件数量，同时还可以简化结构的复杂度。此外，弹性件12包括支撑部121、第一弯折部122、第二弯折部123和连接部124，与相关技术中的在折弯处设置齿轮相比，还可以简化折弯处结构的复杂度，有利于降低折弯处的厚度，从而可以实现显示装置100的轻薄化。According to the flexible hinge 1 of the embodiment of the present invention, the flexible hinge 1 includes: a connecting rod 11 and an elastic member 12, and the elastic member 12 is respectively connected to the two sides of the flexible display module 2 opposite to each other in the second direction. When the flexible display module 2 is folded or unfolded, the elastic member 12 can be elastically deformed with the connecting rod 11 as the rotation center, so that only the connecting rod 11 and the elastic member 12 need to be provided to realize the folding and unfolding of the flexible display module 2, thereby reducing the number of parts of the flexible hinge 1 and simplifying the complexity of the structure. In addition, the elastic member 12 includes a supporting portion 121, a first bending portion 122, a second bending portion 123 and a connecting portion 124. Compared with the related art of providing a gear at the bending portion, the complexity of the structure at the bending portion can be simplified, which is conducive to reducing the thickness of the bending portion, thereby realizing the thinness of the display device 100.
在本发明的一些实施例中，如图1所示，弹性件12为多个，多个弹性件12在第一方向上间隔开设置。由此，弹性件12可以实现柔性显示模块2与连杆11之间的连接和限位，通过在第一方向上，设置多个间隔开的弹性件12，由此可以在第一方向的多个位置处，实现柔性显示模块2与连杆11之间的连接和限位，从而可以提升柔性显示模块2与连杆11相对转动的可靠性和稳定性。In some embodiments of the present invention, as shown in FIG1 , there are multiple elastic members 12, and the multiple elastic members 12 are spaced apart in the first direction. Thus, the elastic member 12 can realize the connection and limit between the flexible display module 2 and the connecting rod 11. By arranging multiple spaced apart elastic members 12 in the first direction, the connection and limit between the flexible display module 2 and the connecting rod 11 can be realized at multiple positions in the first direction, thereby improving the reliability and stability of the relative rotation between the flexible display module 2 and the connecting rod 11.
在本发明的一些实施例中，如图1和图5所示，连杆11上设有第一连接孔111，支撑部121上设有第二连接孔1211，连杆11和支撑部121通过第一连接孔111和第二连接孔1211铆接连接。可以理解的是，连杆11和支撑部121的厚度较薄，且横截面均为弧形，通过铆接连接不仅可以降低连接的难度，同时还可以保证连接的强度。In some embodiments of the present invention, as shown in FIG1 and FIG5, a first connection hole 111 is provided on the connecting rod 11, and a second connection hole 1211 is provided on the supporting portion 121, and the connecting rod 11 and the supporting portion 121 are riveted to each other through the first connection hole 111 and the second connection hole 1211. It can be understood that the connecting rod 11 and the supporting portion 121 are relatively thin, and both have arc-shaped cross-sections, and the riveted connection can not only reduce the difficulty of connection, but also ensure the strength of the connection.
具体地，在本发明的一个示例中，第一连接孔111为两个，两个第一连接孔111在连杆11的长度方向上间隔开，第二连接孔1211为两个，两个第二连接孔1211在支撑部121的长度方向上间隔开，且两个第二连接孔1211与两个第一连接孔111一一对应。Specifically, in one example of the present invention, there are two first connection holes 111, the two first connection holes 111 are spaced apart in the length direction of the connecting rod 11, there are two second connection holes 1211, the two second connection holes 1211 are spaced apart in the length direction of the support portion 121, and the two second connection holes 1211 correspond one-to-one to the two first connection holes 111.
在本发明的一些实施例中，连杆11的横截面形成为圆弧形，连杆11横截面的圆心角为α，且满足：90°≤α≤120°。可以理解的是，通过将连杆11横截面的圆心角设置在90°-120°，可以在不干涉第一弯折部122变形的同时，增大连杆11对柔性显示模块2的支撑面积，从而提升弯折过程中，显示装置100结构的可靠性。In some embodiments of the present invention, the cross section of the connecting rod 11 is formed into an arc shape, the center angle of the cross section of the connecting rod 11 is α, and satisfies: 90°≤α≤120°. It can be understood that by setting the center angle of the cross section of the connecting rod 11 to 90°-120°, the supporting area of the connecting rod 11 for the flexible display module 2 can be increased without interfering with the deformation of the first bending portion 122, thereby improving the reliability of the display device 100 structure during the bending process.
在本发明的一些实施例中，如图3和图4所示，第一弯折部122的凹侧经过减薄处理后形成第一减薄区1221。可以理解的是，在柔性显示模块2折叠过程中，第一弯折部122的凹侧为折叠侧，通过在第一弯折部122的凹侧设置第一减薄区1221，使得第一减薄区1221的位置处的结构强度较弱，也就是说，第一弯折部122的凹侧的第一减薄区1221更容易发生折叠，由此可以保证每次柔性显示模块2折叠过程中均可以在第一减薄区1221的位置处进行弯折，从而可以限制第一弯折部122的凹侧的具体折叠位置。In some embodiments of the present invention, as shown in FIG3 and FIG4, the concave side of the first bending portion 122 is thinned to form a first thinning area 1221. It can be understood that during the folding process of the flexible display module 2, the concave side of the first bending portion 122 is the folding side, and by providing the first thinning area 1221 on the concave side of the first bending portion 122, the structural strength at the position of the first thinning area 1221 is weaker, that is, the first thinning area 1221 on the concave side of the first bending portion 122 is more likely to fold, thereby ensuring that the flexible display module 2 can be bent at the position of the first thinning area 1221 during each folding process, thereby limiting the specific folding position of the concave side of the first bending portion 122.
在本发明的一些实施例中，如图3和图4所示，第一弯折部122的凸侧经过减薄处理后形成第二减薄区1222。可以理解的是，在柔性显示模块2折叠过程中，第一弯折部122的凸侧为拉伸侧，通过在第一弯折部122的凸侧设置第二减薄区1222，使得第二减薄区1222的位置处的结构强度较弱，也就是说，第一弯折部122的凸侧的第二减薄区1222更容易发生拉伸，由此可以保证每次柔性显示模块2折叠过程中均可以在第二减薄区1222的位置处进行拉伸，从而可以限制第一弯折部122的凸侧的具体拉伸位置。In some embodiments of the present invention, as shown in FIG3 and FIG4, the convex side of the first bending portion 122 is thinned to form a second thinning area 1222. It can be understood that during the folding process of the flexible display module 2, the convex side of the first bending portion 122 is the stretching side, and by providing the second thinning area 1222 on the convex side of the first bending portion 122, the structural strength at the position of the second thinning area 1222 is weaker, that is, the second thinning area 1222 on the convex side of the first bending portion 122 is more likely to be stretched, thereby ensuring that each time the flexible display module 2 is folded, it can be stretched at the position of the second thinning area 1222, thereby limiting the specific stretching position of the convex side of the first bending portion 122.
在本发明的一些实施例中，如图3和图4所示，第二弯折部123的凹侧经过减薄处理后形成第三减薄区1231。可以理解的是，在柔性显示模块2拉伸过程中，第二弯折部123的凹侧为拉伸侧，通过在第二弯折部123的凹侧设置第三减薄区1231，使得第三减薄区1231的位置处的结构强度较弱，也就是说，第二弯折部123的凹侧的第三减薄区1231更容易发生拉伸，由此可以保证每次柔性显示模块2拉伸过程中均可以在第三减薄区1231的位置处进行弯折，从而可以限制第二弯折部123的凹侧的具体拉伸位置。In some embodiments of the present invention, as shown in FIG3 and FIG4, the concave side of the second bending portion 123 is thinned to form a third thinning area 1231. It can be understood that during the stretching process of the flexible display module 2, the concave side of the second bending portion 123 is the stretching side, and by providing the third thinning area 1231 on the concave side of the second bending portion 123, the structural strength at the position of the third thinning area 1231 is weaker, that is, the third thinning area 1231 on the concave side of the second bending portion 123 is more likely to be stretched, thereby ensuring that the flexible display module 2 can be bent at the position of the third thinning area 1231 during each stretching process, thereby limiting the specific stretching position of the concave side of the second bending portion 123.
在本发明的一些实施例中，如图3和图4所示，第二弯折部123的凸侧经过减薄处理后形成第四减薄区1232。可以理解的是，在柔性显示模块2折叠过程中，第二弯折部123的凸侧为折叠侧，通过在第二弯折部123的凸侧设置第四减薄区1232，使得第四减薄区1232的位置处的结构强度较弱，也就是说，第二弯折部123的凸侧的第四减薄区1232更容易发生折叠，由此可以保证每次柔性显示模块2折叠过程中均可以在第四减薄区1232的位置处进行弯折，从而可以限制第二弯折部123的凸侧的具体折叠位置。In some embodiments of the present invention, as shown in FIG3 and FIG4, the convex side of the second bending portion 123 is thinned to form a fourth thinning area 1232. It can be understood that during the folding process of the flexible display module 2, the convex side of the second bending portion 123 is the folding side, and by providing the fourth thinning area 1232 on the convex side of the second bending portion 123, the structural strength at the position of the fourth thinning area 1232 is weaker, that is, the fourth thinning area 1232 on the convex side of the second bending portion 123 is more likely to fold, thereby ensuring that the flexible display module 2 can be bent at the position of the fourth thinning area 1232 during each folding process, thereby limiting the specific folding position of the convex side of the second bending portion 123.
在本发明的一些实施例中，如图6所示，第一弯折部122上设有第一贯穿孔1223，第一贯穿孔1223为多个，多个第一贯穿孔1223在第一方向上间隔开。可以理解的是，通过在第一方向上设置多个间隔开的第一贯穿孔1223，第一贯穿孔1223所在位置的弹性强度较小，在柔性显示模块2折叠或展开的过程中，可以保证在第一弯折部122的第一贯穿孔1223所在的位置处出现弯折。In some embodiments of the present invention, as shown in FIG6 , a first through hole 1223 is provided on the first bending portion 122, and there are a plurality of first through holes 1223, and the plurality of first through holes 1223 are spaced apart in the first direction. It can be understood that by providing a plurality of spaced apart first through holes 1223 in the first direction, the elastic strength at the location where the first through holes 1223 are located is relatively small, and during the folding or unfolding process of the flexible display module 2, it can be ensured that the first through holes 1223 of the first bending portion 122 are bent at the location where the first through holes 1223 are located.
在本发明的一些实施例中，如图6所示，第二弯折部123上设有第二贯穿孔1233，第二贯穿孔1233为多个，多个第二贯穿孔1233在第一方向上间隔开。可以理解的是，通过在第一方向上设置多个间隔开的第二贯穿孔1233，第二贯穿孔1233所在位置的弹性强度较小，在柔性显示模块2折叠或展开的过程中，可以保证在第二弯折部123的第二贯穿孔1233所在的位置处出现弯折。In some embodiments of the present invention, as shown in FIG6 , a second through hole 1233 is provided on the second bending portion 123, and there are a plurality of second through holes 1233, and the plurality of second through holes 1233 are spaced apart in the first direction. It can be understood that by providing a plurality of spaced apart second through holes 1233 in the first direction, the elastic strength at the location where the second through holes 1233 are located is relatively small, and during the folding or unfolding process of the flexible display module 2, it can be ensured that the second bending portion 123 is bent at the location where the second through holes 1233 are located.
在本发明的一些实施例中，如图5和图6所示，连接部124形成为平板状。可以理解的是，柔性显示模块2相对平整，通过将与柔性显示模块2连接的连接部124设置成平板状，使得连接部124与柔性显示模块2更容易连接，而且，连接部124还可以为柔性显示模块2提供支撑。In some embodiments of the present invention, as shown in FIG5 and FIG6, the connection portion 124 is formed in a flat plate shape. It can be understood that the flexible display module 2 is relatively flat, and by setting the connection portion 124 connected to the flexible display module 2 in a flat plate shape, the connection portion 124 is easier to connect to the flexible display module 2, and the connection portion 124 can also provide support for the flexible display module 2.
在本发明的一些实施例中，如图7-图9所示，在第二方向上，柔性显示模块2相对的两侧分别设有第一限位件1243和第二限位件1244，两个连接部124包括：第一连接部124和第二连接部124，第一连接部124上设有安装孔1241，第一限位件1243插设在安装孔1241。可以理解的是，安装孔1241对第一限位件1243具有限位作用，而且第一限位件1243与安装孔1241不存在相对的位移，在柔性显示模块2进行折叠或展开的过程中，第一限位件1243可以跟随第一连接部124同步运动。In some embodiments of the present invention, as shown in FIGS. 7 to 9 , in the second direction, the flexible display module 2 is provided with a first stopper 1243 and a second stopper 1244 on opposite sides, respectively, and the two connecting parts 124 include: a first connecting part 124 and a second connecting part 124, the first connecting part 124 is provided with a mounting hole 1241, and the first stopper 1243 is inserted in the mounting hole 1241. It can be understood that the mounting hole 1241 has a limiting effect on the first stopper 1243, and there is no relative displacement between the first stopper 1243 and the mounting hole 1241, and the first stopper 1243 can move synchronously with the first connecting part 124 during the folding or unfolding of the flexible display module 2.
如图7-图9所示，第二连接部124上设有沿第二方向延伸的腰型孔1242，第二限位件1244可移动地设在腰型孔1242内，柔性显示模块2在折叠位置和展开位置之间运动时，第二限位件1244适于从腰型孔1242的一端移动至另一端。其中，腰型孔1242包括两条平行的直线段和两个半圆弧，其中，两条直线段的两端分别平齐，两条直线段的两端分别连接有一个半圆弧，且每个半圆弧朝向腰型孔1242的外侧凸出，每个半圆弧均与两条直线段相切。As shown in FIGS. 7 to 9 , a waist-shaped hole 1242 extending along the second direction is provided on the second connection portion 124, and a second stopper 1244 is movably provided in the waist-shaped hole 1242. When the flexible display module 2 moves between the folded position and the unfolded position, the second stopper 1244 is adapted to move from one end to the other end of the waist-shaped hole 1242. The waist-shaped hole 1242 includes two parallel straight line segments and two semicircular arcs, wherein the two ends of the two straight line segments are respectively flush, and the two ends of the two straight line segments are respectively connected to a semicircular arc, and each semicircular arc protrudes toward the outside of the waist-shaped hole 1242, and each semicircular arc is tangent to the two straight line segments.
可以理解的是，柔性显示模块2折叠过程中，第二限位件1244可以沿着腰型孔1242的延伸方向朝向腰型孔1242的一端移动，当第二限位件1244与腰型孔1242的一端止抵时，表明柔性显示模块2已经折叠到位；柔性显示模块2展开过程中，第二限位件1244可以沿着腰型孔1242的延伸方向朝向腰型孔1242的另一端移动，当第二限位件1244与腰型孔1242的另一端止抵时，表明柔性显示模块2已经展开到位。It can be understood that during the folding process of the flexible display module 2, the second limiting member 1244 can move along the extension direction of the waist-shaped hole 1242 toward one end of the waist-shaped hole 1242. When the second limiting member 1244 stops at one end of the waist-shaped hole 1242, it indicates that the flexible display module 2 has been folded into place; during the unfolding process of the flexible display module 2, the second limiting member 1244 can move along the extension direction of the waist-shaped hole 1242 toward the other end of the waist-shaped hole 1242. When the second limiting member 1244 stops at the other end of the waist-shaped hole 1242, it indicates that the flexible display module 2 has been unfolded into place.

When the flexible display module 2 is folded or unfolded, the elastic member 12 can be elastically deformed with the connecting rod 11 as the rotation center, so that only the connecting rod 11 and the elastic member 12 need to be provided to realize the folding and unfolding of the flexible display module 2, thereby reducing the number of parts of the flexible hinge 1 and simplifying the complexity of the structure. In addition, the elastic member 12 includes a supporting portion 121, a first bending portion 122, a second bending portion 123 and a connecting portion 124. Compared with the related art of providing a gear at the bending portion, the complexity of the structure at the bending portion can be simplified, which is conducive to reducing the thickness of the bending portion, thereby realizing the thinness of the display device 100.
在本发明的一些实施例中，如图7-图9所示，柔性显示模块2包括：缓冲支架21、第一中壳22、第二中壳23和柔性显示屏24，第一中壳22与缓冲支架21的第二方向的一端连接，第二中壳23与缓冲支架21的第二方向的另一端连接，柔性显示屏24与缓冲支架21、第一中壳22和第二中壳23连接，且柔性显示屏24与缓冲支架21层叠设置，柔性铰链1和柔性显示屏24分布与缓冲支架21的厚度方向的两侧，两个连接部124分别与第一中壳22和第二中壳23连接，连杆11朝向靠近缓冲支架21的方向凸出。In some embodiments of the present invention, as shown in Figures 7 to 9, the flexible display module 2 includes: a buffer bracket 21, a first middle shell 22, a second middle shell 23 and a flexible display screen 24, the first middle shell 22 is connected to one end of the buffer bracket 21 in the second direction, the second middle shell 23 is connected to the other end of the buffer bracket 21 in the second direction, the flexible display screen 24 is connected to the buffer bracket 21, the first middle shell 22 and the second middle shell 23, and the flexible display screen 24 is stacked with the buffer bracket 21, the flexible hinge 1 and the flexible display screen 24 are distributed on both sides of the thickness direction of the buffer bracket 21, the two connecting parts 124 are respectively connected to the first middle shell 22 and the second middle shell 23, and the connecting rod 11 protrudes in the direction close to the buffer bracket 21.
可以理解的是，第一中壳22和第二中壳23可以在第二方向的两侧对柔性显示屏24提供连接和支撑，缓冲支架21可以在柔性显示屏24的中间位置对柔性显示屏24提供支撑，具体地，柔性铰链1分布于缓冲支架21的背离柔性显示屏24的一侧，柔性铰链1可以为缓冲支架21提供支撑，并通过缓冲直接对柔性显示屏24提供间接的支撑和限位。It can be understood that the first middle shell 22 and the second middle shell 23 can provide connection and support for the flexible display screen 24 on both sides of the second direction, and the buffer bracket 21 can provide support for the flexible display screen 24 at the middle position of the flexible display screen 24. Specifically, the flexible hinge 1 is distributed on the side of the buffer bracket 21 away from the flexible display screen 24. The flexible hinge 1 can provide support for the buffer bracket 21 and directly provide indirect support and limitation to the flexible display screen 24 through buffering.
具体地，在本发明的一个示例中，柔性显示模块2包括：缓冲支架21、第一中壳22、第二中壳23和柔性显示屏24，缓冲支架21的两端分别与第一中壳22、第二中壳23连接，缓冲支架21的两端与第一中壳22、第二中壳23完全固定，柔性显示屏24贴附在缓冲支架21、第一中壳22和第二中壳23组成的平面上，柔性铰链1和柔性显示屏24分布与缓冲支架21的厚度方向的两侧，柔性显示模块2相对的两侧分别设有第一限位件1243和第二限位件1244，柔性铰链1的两个连接部124包括：第一连接部124和第二连接部124，第一连接部124上设有安装孔1241，第一限位件1243插设在安装孔1241，第二连接部124上设有沿第二方向延伸的腰型孔1242，第二限位件1244可移动地设插设在腰型孔1242内。Specifically, in one example of the present invention, the flexible display module 2 includes: a buffer bracket 21, a first middle shell 22, a second middle shell 23 and a flexible display screen 24, the two ends of the buffer bracket 21 are respectively connected to the first middle shell 22 and the second middle shell 23, the two ends of the buffer bracket 21 are completely fixed to the first middle shell 22 and the second middle shell 23, the flexible display screen 24 is attached to the plane formed by the buffer bracket 21, the first middle shell 22 and the second middle shell 23, and the flexible hinge 1 and the flexible display screen 24 are distributed with the buffer bracket 21. On both sides in the thickness direction, the flexible display module 2 is respectively provided with a first limit member 1243 and a second limit member 1244 on opposite sides, and the two connecting parts 124 of the flexible hinge 1 include: a first connecting part 124 and a second connecting part 124, the first connecting part 124 is provided with a mounting hole 1241, the first limit member 1243 is inserted in the mounting hole 1241, and the second connecting part 124 is provided with a waist-shaped hole 1242 extending along the second direction, and the second limit member 1244 is movably inserted in the waist-shaped hole 1242.
在本发明的一些实施例中，如图7-图9所示，缓冲支架21的朝向连杆11的一侧设有缓冲件25，缓冲件25间隔在缓冲支架21和连杆11之间。可以理解的是，通过在缓冲支架21和连杆11之间设置缓冲件25，利用缓冲件25可以吸收柔性显示屏24组件在折叠或展开过程中产生的振动，避免振动对柔性显示屏24产生影响，从而提升折叠或展开过程的可靠性。In some embodiments of the present invention, as shown in FIGS. 7 to 9 , a buffer 25 is provided on one side of the buffer bracket 21 facing the connecting rod 11, and the buffer 25 is spaced between the buffer bracket 21 and the connecting rod 11. It can be understood that by providing the buffer 25 between the buffer bracket 21 and the connecting rod 11, the buffer 25 can absorb the vibration generated by the flexible display screen 24 assembly during the folding or unfolding process, thereby preventing the vibration from affecting the flexible display screen 24, thereby improving the reliability of the folding or unfolding process.
在本发明的一些实施例中，缓冲支架21的弹性模量大于柔性显示屏24的弹性模量。可以理解的是，缓冲支架21的弹性模量大于柔性显示屏24的弹性模块，也就是说在折叠过程中，缓冲支架21的应变小于柔性显示屏24的应变，由此可以避免柔性显示屏24的弯折处受到拉引力，避免柔性显示屏24出现损坏。In some embodiments of the present invention, the elastic modulus of the buffer bracket 21 is greater than the elastic modulus of the flexible display screen 24. It can be understood that the elastic modulus of the buffer bracket 21 is greater than the elastic modulus of the flexible display screen 24, that is, during the folding process, the strain of the buffer bracket 21 is less than the strain of the flexible display screen 24, thereby preventing the bending part of the flexible display screen 24 from being subjected to pulling force and preventing the flexible display screen 24 from being damaged.
在本发明的一些实施例中，如图9所示，在折叠位置，连杆11的邻近缓冲支架21的一侧与缓冲支架21朝向连杆11的一侧贴合。可以理解的是，连杆11的邻近缓冲支架21的一侧与缓冲支架21朝向连杆11的一侧贴合后，连杆11可以对缓冲支架21的弯折处起到支撑的作用，并利用缓冲支架21进一步对柔性显示屏24进行支撑，避免柔性显示屏24出现损坏。In some embodiments of the present invention, as shown in FIG9 , in the folded position, the side of the connecting rod 11 adjacent to the buffer bracket 21 is in contact with the side of the buffer bracket 21 facing the connecting rod 11. It can be understood that after the side of the connecting rod 11 adjacent to the buffer bracket 21 is in contact with the side of the buffer bracket 21 facing the connecting rod 11, the connecting rod 11 can support the bending part of the buffer bracket 21, and further support the flexible display screen 24 by using the buffer bracket 21 to prevent the flexible display screen 24 from being damaged.
下面参考附图描述根据本发明实施例的电子设备。The electronic device according to the embodiment of the present invention is described below with reference to the accompanying drawings.
根据本发明实施例的电子设备，包括：上述显示装置100。An electronic device according to an embodiment of the present invention includes: the display device 100 described above.
根据本发明实施例的电子设备，柔性铰链1包括：连杆11和弹性件12，利用弹性件12分别与柔性显示模块2的第二方向相对的两侧连接，在柔性显示模块2进行折叠或展开时，弹性件12可以以连杆11为旋转中心发生弹性变形，由此仅需要设置连杆11和弹性件12便可以实现柔性显示模块2的折叠和展开，从而可以减少柔性铰链1的零件数量，同时还可以简化结构的复杂度。此外，弹性件12包括支撑部121、第一弯折部122、第二弯折部123和连接部124，与相关技术中的在折弯处设置齿轮相比，还可以简化折弯处结构的复杂度，有利于降低折弯处的厚度，从而可以实现显示装置100的轻薄化。According to the electronic device of the embodiment of the present invention, the flexible hinge 1 includes: a connecting rod 11 and an elastic member 12, and the elastic member 12 is respectively connected to the two sides of the flexible display module 2 opposite to each other in the second direction. When the flexible display module 2 is folded or unfolded, the elastic member 12 can be elastically deformed with the connecting rod 11 as the rotation center, so that only the connecting rod 11 and the elastic member 12 need to be provided to realize the folding and unfolding of the flexible display module 2, thereby reducing the number of parts of the flexible hinge 1 and simplifying the complexity of the structure. In addition, the elastic member 12 includes a supporting portion 121, a first bending portion 122, a second bending portion 123 and a connecting portion 124. Compared with the related art of providing a gear at the bending portion, the complexity of the structure at the bending portion can be simplified, which is conducive to reducing the thickness of the bending portion, thereby realizing the thinness of the display device 100.
