本申请涉及到电子设备技术领域,尤其涉及到一种转轴机构及电子设备。This application relates to the technical field of electronic equipment, and in particular to a rotating shaft mechanism and electronic equipment.
随着柔性屏技术的发展,柔性屏应用逐渐增多,但是柔性屏本身还是比较脆弱,在弯折过程中不能产生大的拉扯力(避免损坏),在展平时无法保持完全平整。同时,柔性屏在弯折过程中会产生巨大的内部张力,严重影响折叠手感。故需要借助转轴机构提供辅助扭矩。现有的电子设备的转轴机构使用凹凸轮结构作为阻尼组件提供扭矩。如图1所示,该阻尼组件包括凹凸轮结构2,以及与凹凸轮结构2连接的两个支撑板1,两个支撑板1分别与电子设备的两个壳体一一对应固定连接。在折叠时,通过凹凸轮结构2中的两个凹凸轮3的配合来提供壳体折叠所需的辅助力。但是图1中,凹凸轮结构2的旋转轴心与产品设备的转动轴心重合,这就造成要想获得较大的扭矩时,需要较大的凹凸轮3直径和较大的弹性结构件4提供两个凹凸轮3的压力。这就导致整个转轴机构占用空间较大,导致可折叠产品无法做得轻薄。With the development of flexible screen technology, the application of flexible screens has gradually increased, but the flexible screen itself is still relatively fragile, and cannot generate a large pulling force (to avoid damage) during the bending process, and cannot be completely flat when flattened. At the same time, the flexible screen will generate huge internal tension during the bending process, which seriously affects the folding feel. Therefore, the auxiliary torque needs to be provided with the aid of the rotating shaft mechanism. The shaft mechanism of the existing electronic device uses a concave cam structure as a damping component to provide torque. As shown in FIG. 1, the damping assembly includes a concave cam structure 2 and two supporting plates 1 connected to the concave cam structure 2, and the two supporting plates 1 are respectively fixedly connected to the two housings of the electronic device in a one-to-one correspondence. During folding, the auxiliary force required for the folding of the housing is provided by the cooperation of the two concave cams 3 in the concave cam structure 2. However, in Figure 1, the rotation axis of the concave cam structure 2 coincides with the rotation axis of the product equipment, which results in the need for a larger diameter of the concave cam 3 and a larger elastic structural member 4 to obtain a larger torque. The pressure of the two concave cams 3 is provided. As a result, the entire hinge mechanism takes up a lot of space, and the foldable product cannot be made light and thin.

At this time, the first arc arm 42 and the second arc When the shape arm 41 rotates relative to the main shaft assembly, the first support plate 21 drives the third arc arm 42 to rotate, and the second support plate 31 drives the second arc arm 41 to rotate. At the same time, the second convex surface 421b slides relative to the first convex surface 432b, the second convex surface 421b partially abuts the first convex surface 432b; the third convex surface 411b slides relative to the first convex surface 432b, the third surface 411b partially abuts the first convex surface 432b . At this time, the elastic deformation amount of the elastic member is still the first deformation amount.
在电子设备的第一壳体与第二壳体之间的夹角为第二角度时,阻尼块43在弹性件的推动下朝向第一弧形臂42及第二弧形臂41滑动,第二凸面421b与第一凸面脱离接触,第三凸面411b与第一凸面432b脱离接触,同时第一凹面432a抵接第三凹面421a,第二凹面432c抵接第四凹面411a。此时,弹性件的弹性形变量为第二形变量(第一形变量大于第二形变量),通过弹性件的第二形变量,使得第一凹面432a推动第三凹面421a,第一凹面432a给第三凹面421a提供帮助第一弧形臂42转动的力。同时,使得第四凹面411a推动第二凹面432c,第四凹面411a推动第二凹面432c提供帮助第二弧形臂41转动的力。为方便理解第一弧形臂42和第二弧形臂41的受力,以第一弧形臂受力为例进行说明。When the included angle between the first housing and the second housing of the electronic device is the second angle, the damping block 43 slides toward the first arc-shaped arm 42 and the second arc-shaped arm 41 under the push of the elastic member. The two convex surfaces 421b are out of contact with the first convex surface, and the third convex surface 411b is out of contact with the first convex surface 432b. At the same time, the first concave surface 432a abuts the third concave surface 421a, and the second concave surface 432c abuts the fourth concave surface 411a. At this time, the elastic deformation amount of the elastic member is the second deformation amount (the first deformation amount is greater than the second deformation amount), and the second deformation amount of the elastic member causes the first concave surface 432a to push the third concave surface 421a, and the first concave surface 432a The third concave surface 421a is provided with a force that helps the first arcuate arm 42 to rotate. At the same time, the fourth concave surface 411a pushes the second concave surface 432c, and the fourth concave surface 411a pushes the second concave surface 432c to provide a force to help the second arcuate arm 41 rotate. In order to facilitate the understanding of the force exerted by the first arcuate arm 42 and the second arcuate arm 41, the force exerted by the first arcuate arm is taken as an example for description.
如图14所示,由于第三凹面421a与主轴组件的长度方向呈一定的夹角,因此,在第三凹面421a上会分别产生两个分力,第三凹面421a受到的力F=F1+F2,其中,F1为垂直主轴长度方向的分力,F2为平行于主轴组件长度方向的分力。在第一支撑件转动时,垂直于主轴组件长度方向的分力F1可以作为辅助第一支撑件转动的辅助力,推动第一支撑件转动。在电子设备的第一壳体与第二壳体之间的夹角为第二角度时,如第一壳体与第二壳体的夹角为30°时,第四凹面411a与第二凹面432c接触,在弹性件的推动下,推动阻尼块43朝向第一弧形臂42滑动,第一凹面432a推动第三凹面421a从而推动第一弧形臂42转动。As shown in FIG. 14, since the third concave surface 421a and the longitudinal direction of the spindle assembly form a certain angle, two component forces are generated on the third concave surface 421a respectively, and the force received by the third concave surface 421a is F=F1+ F2, where F1 is the force component perpendicular to the length of the main shaft, and F2 is the force component parallel to the length of the main shaft assembly. When the first support member rotates, the component force F1 perpendicular to the longitudinal direction of the main shaft assembly can be used as an auxiliary force to assist the rotation of the first support member to push the first support member to rotate. When the included angle between the first housing and the second housing of the electronic device is the second angle, for example, when the included angle between the first housing and the second housing is 30°, the fourth concave surface 411a and the second concave surface 432c contacts, pushed by the elastic member, pushes the damping block 43 to slide toward the first arc-shaped arm 42, and the first concave surface 432a pushes the third concave surface 421a to push the first arc-shaped arm 42 to rotate.
当第一弧形臂42和第二弧形臂41相对主轴组件转动,使得电子设备的第一壳体与第二壳体之间的夹角为第三角度时,此时电子设备处于折叠状态。如图18所示,弹性件具有第三形变量(第二形变量大于第三形变量),在弹性件的作用下,阻尼块43与限位块抵接,从而限定了阻尼块43的滑动位置,使得第一凹面432a与第三凹面421a间隙配合,同理,第二凹面432c与第四凹面411a间隙配合,从而避免在电子设备折叠时,阻尼块43仍施加力给第一弧形臂42及第二弧形臂41。When the first arc-shaped arm 42 and the second arc-shaped arm 41 rotate relative to the main shaft assembly, so that the included angle between the first housing and the second housing of the electronic device is a third angle, the electronic device is in a folded state at this time . As shown in Figure 18, the elastic member has a third amount of deformation (the second amount of deformation is greater than the third amount of deformation). Under the action of the elastic member, the damping block 43 abuts against the limit block, thereby limiting the sliding movement of the damping block 43. Position such that the first concave surface 432a is in clearance fit with the third concave surface 421a. Similarly, the second concave surface 432c is in clearance fit with the fourth concave surface 411a, so as to prevent the damping block 43 from still applying force to the first arc-shaped arm when the electronic device is folded. 42 and second arcuate arm 41.
由上述描述可以看出,通过设置的几个凸面、凹面之间的配合可以给第一支撑件及第二支撑件转动所需的力,从而可以帮助用户克服在电子设备折叠时,柔性屏产生的张力,方便用户折叠。通过斜坡面的配合,可以方便在折叠后使得电子设备保持折叠状态。It can be seen from the above description that the cooperation between the convex and concave surfaces can give the first support and the second support the force required to rotate, which can help the user overcome the flexible screen when the electronic device is folded. The tension is convenient for users to fold. Through the cooperation of the slope surface, it is convenient to keep the electronic device in the folded state after being folded.
本申请实施例提供的阻尼组件通过阻尼块与第一弧形臂及第二弧形臂的配合提供第一壳体及第二壳体转动所需的扭矩。如图13所示,第一弧形臂42受到的扭矩:T1=r*F1(T1为第一弧形臂42受到的扭矩,r为第一弧形臂42对应的半径,F3为第一弧形臂42受到的摩擦力);第二弧形臂41受到的扭矩:T2=r*F3(T2为第二弧形臂41受到的扭矩,r为第二弧形臂41对应的半径,F3为第二弧形臂41的第四凹面受到的垂直分力);由图13可以看出,第一弧形臂42及第二弧形臂41转动所绕的轴线(O点)位于主轴组件外,r及R的尺寸远大于主轴组件的厚度,因此在第一弧形臂42与第二弧形臂41转动时可以 受到较大的扭矩,相比与图1所示的现有技术中的凹凸轮结构来说,可以提供更大的扭矩。在采用上述结构时,主轴组件的厚度仅需要满足设置弧形滑槽的厚度即可,无需提供整个环形的滑道,因此本申请实施例提供的转轴机构可以在提供较大的扭矩的前提下,厚度小于图1所示的转轴机构的厚度。The damping assembly provided by the embodiment of the present application provides the torque required for the rotation of the first housing and the second housing through the cooperation of the damping block with the first arc-shaped arm and the second arc-shaped arm. As shown in Figure 13, the torque received by the first arc-shaped arm 42: T1=r*F1 (T1 is the torque received by the first arc-shaped arm 42, r is the radius corresponding to the first arc-shaped arm 42, F3 is the first The friction force received by the arc arm 42); the torque received by the second arc arm 41: T2=r*F3 (T2 is the torque received by the second arc arm 41, r is the radius corresponding to the second arc arm 41, F3 is the vertical component force received by the fourth concave surface of the second arc-shaped arm 41); as can be seen from Figure 13, the axis (point O) around which the first arc-shaped arm 42 and the second arc-shaped arm 41 rotate is located on the main shaft Outside of the assembly, the dimensions of r and R are much larger than the thickness of the spindle assembly, so when the first arc-shaped arm 42 and the second arc-shaped arm 41 rotate, they can receive a larger torque, compared with the prior art shown in FIG. 1 For the concave cam structure in the middle, it can provide more torque. When the above structure is adopted, the thickness of the main shaft assembly only needs to meet the thickness of the arc-shaped slide groove, and there is no need to provide the entire annular slide. Therefore, the shaft mechanism provided by the embodiment of the present application can provide a larger torque under the premise , The thickness is smaller than the thickness of the shaft mechanism shown in FIG. 1.
继续参考图13,由于第二弧形臂41位于第一弧形臂42的上方(以图13所示的主轴组件的放置方向为参考方向),因此第二弧形臂41对应的半径R要大于第一弧形臂42对应的半径r。在受到阻尼效果时,通过第一弧形臂及第二弧形臂受到的摩擦力提供。而对于摩擦力满足如下公式:F=μ×Fn,其中F为摩擦力,μ为摩擦系数,Fn为压力。在第一弧形臂42及第二弧形臂41采用相同的材质制备而成时,两者的摩擦系数近似相同。在阻尼块43与第一弧形臂42及第二弧形臂41接触时,第一弧形臂42与阻尼块43接触的面积大于第二弧形臂41与阻尼块43接触的面积时,阻尼块43施加到第一弧形臂42的压力会大于阻尼块43施加到第二弧形臂41上的压力。因此为使得第一弧形臂42及第二弧形臂41受到的阻尼效果近似相等,在设置第一弧形臂42及第二弧形臂41时,第一弧形臂42的厚度大于第二弧形臂41的厚度,其中第一弧形臂42的厚度指的是第二端面421的宽度D,第二弧形臂41的厚度指的是第三端面411的宽度d,D>d。如第二端面421的宽度为第三端面411宽度的1~2倍。在图13中,第二端面421的宽度为第二表面11的宽度的两倍。当然,第二端面421的宽度为第三端面411宽度也可以采用其他的宽度比例,只需要保证第二支撑件30与第一支撑件20受到的阻尼效果近似相等即可。Continuing to refer to FIG. 13, since the second arc-shaped arm 41 is located above the first arc-shaped arm 42 (taking the placement direction of the spindle assembly shown in FIG. 13 as the reference direction), the radius R corresponding to the second arc-shaped arm 41 is It is larger than the radius r corresponding to the first arc-shaped arm 42. When the damping effect is received, it is provided by the friction force received by the first arc-shaped arm and the second arc-shaped arm. The friction force satisfies the following formula: F=μ×Fn, where F is the friction force, μ is the friction coefficient, and Fn is the pressure. When the first arc-shaped arm 42 and the second arc-shaped arm 41 are made of the same material, the friction coefficients of the two are approximately the same. When the damping block 43 is in contact with the first arc-shaped arm 42 and the second arc-shaped arm 41, the contact area of the first arc-shaped arm 42 and the damping block 43 is larger than the contact area of the second arc-shaped arm 41 and the damping block 43, The pressure applied by the damping block 43 to the first arc-shaped arm 42 is greater than the pressure applied by the damping block 43 to the second arc-shaped arm 41. Therefore, in order to make the damping effect of the first arc-shaped arm 42 and the second arc-shaped arm 41 approximately equal, when the first arc-shaped arm 42 and the second arc-shaped arm 41 are arranged, the thickness of the first arc-shaped arm 42 is greater than that of the first arc-shaped arm 42 and the second arc-shaped arm 41. The thickness of the two arc-shaped arms 41, where the thickness of the first arc-shaped arm 42 refers to the width D of the second end surface 421, and the thickness of the second arc-shaped arm 41 refers to the width d of the third end surface 411, D>d . For example, the width of the second end surface 421 is 1 to 2 times the width of the third end surface 411. In FIG. 13, the width of the second end surface 421 is twice the width of the second surface 11. Of course, the width of the second end surface 421 is the width of the third end surface 411 and other width ratios can also be adopted, and it is only necessary to ensure that the damping effects received by the second support member 30 and the first support member 20 are approximately equal.
除上述的对第二端面421及第三端面411的宽度做限定外,在设置第三凹面421a及第四凹面411a时,第三凹面421a的坡度大于第四凹面411a的坡度,从而达到在第三凹面421a与第一凹面432a配合、第四凹面411a与第二凹面432c配合时,能够给第一支撑件20及第二支撑件30提供近似相等的推动力,以使得第一支撑件20与第二支撑件30可以同步转动。In addition to the above-mentioned limitation on the width of the second end surface 421 and the third end surface 411, when the third concave surface 421a and the fourth concave surface 411a are provided, the slope of the third concave surface 421a is greater than the slope of the fourth concave surface 411a, so as to achieve the When the three concave surfaces 421a cooperate with the first concave surface 432a and the fourth concave surface 411a cooperates with the second concave surface 432c, they can provide approximately equal pushing force to the first support 20 and the second support 30, so that the first support 20 and The second support 30 can rotate synchronously.
在设置上述第三凹面及第一凹面时,可以采用如图14及图16所示的方式设置,也可以第一弧形臂42上设置两个第三凹面421a,第二弧形臂41上设置两个第四凹面411a,此时对应的阻尼块43上的第一凹面432a及第二凹面432c也为两个。此时阻尼块43会通过斜坡面的配合提供电子设备在展开以及折叠时的辅助力,可以在展开时提供展平的保持力。When the above-mentioned third concave surface and the first concave surface are provided, they can be arranged in the manner shown in Figures 14 and 16, or two third concave surfaces 421a can be provided on the first arc-shaped arm 42 and the second arc-shaped arm 41 Two fourth concave surfaces 411a are provided. At this time, there are also two first concave surfaces 432a and second concave surfaces 432c on the corresponding damping block 43. At this time, the damping block 43 will provide the auxiliary force when the electronic device is unfolded and folded through the cooperation of the slope surface, and can provide the flattening holding force when unfolding.
如图17所示,在阻尼块43滑动到设定位置时,限位块12抵接在阻尼块43上,并对阻尼块43的行程限位,从而避免阻尼块43给第一弧形臂42及第二弧形臂41过大的力,防止在电子设备展开过程的起始阶段造成第一支撑件20及第二支撑件30受力倾斜导致卡滞、卡死的情况,改善了电子设备的使用效果。As shown in Figure 17, when the damping block 43 slides to the set position, the limit block 12 abuts on the damping block 43 and limits the stroke of the damping block 43, thereby preventing the damping block 43 from giving the first arc-shaped arm The excessive force of 42 and the second arc-shaped arm 41 prevents the first support member 20 and the second support member 30 from being forced to tilt during the initial stage of the deployment process of the electronic device to cause jamming and jamming, thereby improving the electronic equipment The use effect of the equipment.
如图18所示,在电子设备处于折叠状态时,第一弧形臂42及第二弧形臂41之间脱离接触,为了方便在电子设备展开过程中,第一弧形臂42及第二弧形臂41层叠,在设置第一弧形臂42及第二弧形臂41时,在第一弧形臂42及第二弧形臂41的端部分别设置配合的斜坡面(图中未标示),通过该斜坡面可以进行导向。As shown in Figure 18, when the electronic device is in the folded state, the first arc-shaped arm 42 and the second arc-shaped arm 41 are out of contact. In order to facilitate the unfolding process of the electronic device, the first arc-shaped arm 42 and the second arc-shaped arm The arc-shaped arms 41 are stacked. When the first arc-shaped arm 42 and the second arc-shaped arm 41 are provided, the ends of the first arc-shaped arm 42 and the second arc-shaped arm 41 are respectively provided with matching slope surfaces (not shown in the figure). Mark), through the slope surface can be guided.
为方便第一弧形臂及第二弧形臂脱离主轴组件,也可以采用上述第三弧形臂及第四弧形臂中设置限位凸台的方式来防止第一弧形臂及第二弧形臂脱离弧形滑槽,具体结构可以参考上述的描述,在此不再详细赘述。In order to facilitate the separation of the first arc-shaped arm and the second arc-shaped arm from the main shaft assembly, the above-mentioned third arc-shaped arm and the fourth arc-shaped arm can also be provided with a limiting boss to prevent the first arc-shaped arm and the second arc-shaped arm from The arc-shaped arm is separated from the arc-shaped sliding groove, and the specific structure can be referred to the above description, which will not be described in detail here.

Continuing to refer to FIG. 2a, the rotating shaft mechanism 100 is connected to the first housing 200 and the second housing 300 respectively. The rotation of the rotating shaft mechanism 100 causes the first housing 200 and the second housing 300 to rotate relatively, and the flexible screen 400 covers The first housing 200, the second housing 300, and the rotating shaft mechanism 100 are respectively bonded to the first housing 200 and the second housing 300. When in use, the electronic device includes two states: an expanded state and a folded state. As shown in FIG. 2a, when the electronic device is unfolded, the first housing 200 and the second housing 300 are arranged separately on both sides of the rotating shaft mechanism 100, and the flexible screen 400 is unfolded at this time.

The first housing 200 and the second housing 300 are relatively stacked, and The flexible screen (not shown in the figure) is bent following the first housing 200 and the second housing 300. Figure 2b shows the folding method in which the flexible screen is located inside the electronic device. However, the electronic device provided by the embodiment of the present application is not limited to the folding method shown in Figure 2b, and can also be folded in a manner that the flexible screen is exposed after folding. When the above-mentioned shaft mechanism 100 is used, the arc sliding groove is arranged in the main shaft assembly, so that the axis of the arc sliding groove is located outside the main shaft assembly, and when the damping assembly is set, the first arc arm and the second arc arm Slide along the arc-shaped chute. At this time, the first arc-shaped arm and the second arc-shaped arm rotate around the axis of the arc-shaped chute. When the damping block abuts on the first arc-shaped arm and the second arc-shaped arm, the first arc-shaped arm and the second arc-shaped arm are An arc-shaped arm and a second arc-shaped arm can obtain a larger torque, which realizes the effect of using a thinner mechanism to provide a larger torque. Improve the folding effect of electronic equipment.
