具体实施方式Detailed ways

本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application and are not intended to limit the present application.

相关技术中，可折叠电子设备可以包括两个中框，两个中框之间通过折叠装置连接，使得两个中框能够相对发生转动，进而使两个中框可以相互叠合或展开。折叠装置通常包括铰链组件和位于铰链组件两侧的连接件，铰链组件与两个连接件之间转动连接，铰链组件与连接件之间需要设计有效的阻尼，才能够实现折叠装置在任意角度下的悬停，从而实现电子设备在任意角度下的悬停。In the related art, a foldable electronic device may include two middle frames. The two middle frames are connected by a folding device so that the two middle frames can rotate relative to each other, so that the two middle frames can be overlapped or unfolded with each other. The folding device usually includes a hinge component and connectors located on both sides of the hinge component. The hinge component is rotationally connected to the two connectors. Effective damping needs to be designed between the hinge component and the connectors to achieve the folding device at any angle. Hovering enables electronic devices to hover at any angle.

然而，铰链组件与连接件之间尚未设计有效的阻尼，使得折叠装置的悬停效果较差，从而导致电子设备的悬停效果较差。因此，需要改善铰链组件与连接件之间的阻尼设计，以保证折叠装置和电子设备的悬停效果。However, effective damping has not been designed between the hinge assembly and the connecting piece, resulting in a poor hovering effect of the folding device, resulting in a poor hovering effect of the electronic device. Therefore, it is necessary to improve the damping design between the hinge assembly and the connecting piece to ensure the hovering effect of the folding device and electronic equipment.

基于上述问题，本申请实施例提供一种折叠装置及电子设备，折叠装置可以包括铰链组件、连接件、联动件和第一弹性件，铰链组件和连接件通过联动件转动连接；联动件包括相连的第一端和第二端，第一端和铰链组件转动连接，第二端与连接件滑动连接。第二端和连接件中的至少一者与第一弹性件配合，以使第二端与连接件抵接。由于第二端与连接件在第一弹性件的作用下抵接，在第二端相对于连接件滑动时，第二端与连接件之间产生滑动摩擦力，从而产生阻止第二端相对于连接件滑动的阻尼。当用户施加的外力大于阻尼时，可以使折叠装置折叠或展开至任意角度。当用户撤去外力时，由于阻尼的存在，能够确保折叠装置和电子设备在该任意角度下的悬停，从而可以提高用户的使用手感。Based on the above problems, embodiments of the present application provide a folding device and electronic equipment. The folding device may include a hinge assembly, a connecting piece, a linking piece and a first elastic piece. The hinge assembly and the connecting piece are rotationally connected through the linking piece; the linking piece includes a connecting piece. The first end and the second end are rotatably connected to the hinge assembly, and the second end is slidingly connected to the connecting piece. At least one of the second end and the connecting piece cooperates with the first elastic member, so that the second end abuts the connecting piece. Since the second end and the connecting piece are in contact under the action of the first elastic member, when the second end slides relative to the connecting piece, sliding friction is generated between the second end and the connecting piece, thereby preventing the second end from sliding relative to the connecting piece. Damping of joint sliding. When the external force exerted by the user is greater than the damping, the folding device can be folded or unfolded to any angle. When the user removes the external force, due to the existence of damping, the folding device and the electronic device can be ensured to hover at any angle, thereby improving the user's use feel.

或者，中框130可以包括两个，例如，两个中框130可以包括第一中框131和第二中框132，第一中框131和第二中框132位于折叠装置200的两侧，第一中框131和第二中框132分别与折叠装置200连接。其中，两个中框130通过折叠装置200转动连接，从而使两个中框130能够相对转动，也即第一中框131和第二中框132可以发生相对的转动。Alternatively, the middle frame 130 may include two. For example, the two middle frames 130 may include a first middle frame 131 and a second middle frame 132. The first middle frame 131 and the second middle frame 132 are located on both sides of the folding device 200. The first middle frame 131 and the second middle frame 132 are connected to the folding device 200 respectively. The two middle frames 130 are rotationally connected through the folding device 200, so that the two middle frames 130 can rotate relative to each other, that is, the first middle frame 131 and the second middle frame 132 can rotate relative to each other.

For example, when the first middle frame 131 and the second middle frame 132 are in the open state, they may be approximately 180° (a slight deviation is also allowed, such as 165°, 177° or 185°). At this time, the electronic device 100 is in the open state, also known as the flat state.

参见图2所示，第一中框131和第二中框132能够相对转动(折叠或展开)至中间状态，以使电子设备100处于中间状态。其中，中间状态，可以为打开状态与闭合状态之间的任意状态。也即电子设备100可以通过折叠装置200的运动，在打开状态(也即展平状态)与闭合状态(也即折叠状态)之间相互切换。Referring to FIG. 2 , the first middle frame 131 and the second middle frame 132 can relatively rotate (fold or unfold) to the intermediate state, so that the electronic device 100 is in the intermediate state.

The second end 232 is the end of the linkage member 230 close to the connector 220. The second end 232 and the connector 220 can be slidably connected.

例如，每个连接件220与铰链组件210之间可以设置有至少一个联动件230，每个连接件220与铰链组件210之间的联动件230的数量可以是1个、2个、3个或4个及以上。For example, at least one linkage 230 may be provided between each connection member 220 and the hinge assembly 210, and the number of linkage members 230 between each connection member 220 and the hinge assembly 210 may be 1, 2, 3, or 4 and above.

The second linkage member 230b can drive the second middle frame 132 to rotate through the second connection member 220b, thereby realizing the linkage between the first middle frame 131 and the second middle frame 132, so that the first middle frame 131 and the second middle frame 132 Able to rotate synchronously. In this way, when unfolding or folding the electronic device 100, you only need to drive the middle frame 130 on one side to rotate to drive the middle frame 130 on the other side to rotate, thereby realizing the folding or unfolding of the electronic device 100, making the operation more convenient and helping to improve the user experience. .

具体的，铰链组件210还包括同步组件，同步组件分别与第一联动件230a和第二联动件230b连接，以用于实现第一联动件230a和第二联动件230b之间的同步转动，从而实现第一连接件220a与第二连接件220b之间的同步转动。同步组件的实施方式将在后续实施例中阐明Specifically, the hinge assembly 210 also includes a synchronization assembly, which is connected to the first linkage part 230a and the second linkage part 230b respectively, for realizing synchronous rotation between the first linkage part 230a and the second linkage part 230b, so that Synchronous rotation between the first connecting member 220a and the second connecting member 220b is achieved.

The connecting member 220 and the second end Another one of 232 may be provided with a sliding member 232a (Fig. 9), and the sliding member 232a may be slidably connected to the first coordinating groove 222. For example, as shown in FIG. 9 , the connecting piece 220 can be provided with a fitting piece 221 , a first fitting groove 222 is opened in the fitting piece 221 of the connecting piece 220 , and a sliding piece 232 a can be set on the second end 232 . Alternatively, the connecting member 220 may be provided with a sliding member 232a, the second end 232 may be provided with a coordinating member 221, and a first coordinating slot 222 may be opened in the coordinating member 221 of the second end 232.

本申请以连接件220上设置有第一配位槽222，第二端232上设置有滑动件232a为例进行说明。This application takes as an example that the connecting member 220 is provided with the first coordination groove 222 and the second end 232 is provided with the sliding member 232a.

如图9所示，连接件220可以包括配位件221，第一配位槽222开设在配位件221中。第一配位槽222从连接件220面向铰链组件210的一端延伸至连接件220背向铰链组件210的一端，当连接件220相对铰链组件210转动时，联动件230相对铰链组件210转动，且联动件230上的滑动件232a沿第一配位槽222的延伸方向滑动。其中，滑动件232a可以由部分的第二端232形成，或者，滑动件232a可以由全部的第二端232形成。As shown in FIG. 9 , the connecting piece 220 may include a fitting piece 221 , and a first fitting groove 222 is opened in the fitting piece 221 . The first coordinating groove 222 extends from the end of the connecting member 220 facing the hinge assembly 210 to the end of the connecting member 220 facing away from the hinge assembly 210. When the connecting member 220 rotates relative to the hinge assembly 210, the linkage member 230 rotates relative to the hinge assembly 210, and The sliding member 232a on the linkage member 230 slides along the extending direction of the first coordination groove 222. The sliding member 232a may be formed by part of the second end 232, or the sliding member 232a may be formed by the entire second end 232.

一些实施例中，折叠装置200可以包括第一弹性件271(图10)，第二端232和连接件220中的至少一者与第一弹性件271配合，以使第二端232与连接件220抵接。例如，可以是滑动件232a与配位件221抵接。In some embodiments, the folding device 200 may include a first elastic member 271 (Fig. 10), and at least one of the second end 232 and the connecting member 220 cooperates with the first elastic member 271, so that the second end 232 and the connecting member 220 docking. For example, the sliding member 232a may be in contact with the fitting member 221.

一些示例中，滑动件232a可以靠近或远离配位件221运动，第一弹性件271可以与滑动件232a连接，并通过驱动滑动件232a靠近配位件221，以使滑动件232a抵接在配位件221上。在折叠装置200的弯折过程中，滑动件232a相对于配位件221滑动，由于滑动件232a与配位件221抵接，滑动件232a在滑动过程中与配位件221产生滑动摩擦力，从而产生阻止滑动件232a滑动的阻尼。当用户施加的外力大于该阻尼时，可以使折叠装置200折叠或展开至任意角度。当用户撤去外力时，由于阻尼的存在，能够确保折叠装置200和电子设备在该任意角度下的悬停，从而可以提高用户的使用手感。其中，第一弹性件271与滑动件232a可以直接连接，或者，通过其他结构部件间接连接。In some examples, the sliding member 232a can move closer to or away from the matching member 221, and the first elastic member 271 can be connected with the sliding member 232a, and drive the sliding member 232a close to the matching member 221, so that the sliding member 232a abuts against the matching member 221. on bit 221. During the bending process of the folding device 200, the sliding member 232a slides relative to the coordinating member 221. Since the sliding member 232a abuts the coordinating member 221, the sliding member 232a generates sliding friction with the coordinating member 221 during the sliding process. This creates damping that prevents the sliding member 232a from sliding. When the user applies an external When the force is greater than the damping, the folding device 200 can be folded or unfolded to any angle. When the user removes the external force, due to the existence of damping, the folding device 200 and the electronic device can be ensured to hover at any angle, thereby improving the user's use feel. The first elastic member 271 and the sliding member 232a may be directly connected, or indirectly connected through other structural components.

可以理解的是，滑动件232a与配位件221之间的摩擦力可以分解为沿电子设备100的厚度方向(即图3中的第三方向Z)的第一摩擦分力，以及沿电子设备100所在平面(即图3中XY平面)的第二摩擦分力，主要由第一摩擦分力提供阻尼以阻止连接件220和铰链组件210之间相对转动，从而为折叠装置200提供阻尼。当用户施加的外力大于阻尼时，可以实现折叠装置200的折叠或展开。It can be understood that the friction force between the sliding member 232a and the fitting member 221 can be decomposed into a first friction component along the thickness direction of the electronic device 100 (ie, the third direction Z in FIG. 3), and a first friction component along the thickness direction of the electronic device 100, and a friction force along the thickness direction of the electronic device 100. The second friction component on the plane where 100 is located (i.e., the XY plane in FIG. 3 ) is mainly provided with damping by the first friction component to prevent relative rotation between the connecting piece 220 and the hinge assembly 210 , thereby providing damping for the folding device 200 . When the external force exerted by the user is greater than the damping, the folding device 200 can be folded or unfolded.

若联动件230在运动(转动和/或滑动)过程中不受到阻尼，联动件230可以在任意的外力作用下运动，从而导致折叠装置200无法保持在用户所希望的使用角度，即无法悬停，导致用户的使用手感较差。例如，当用户施加外力以折叠手机时，手机上的柔性屏110受力形变弯折且折叠装置200折叠；当用户撤掉外力后，柔性屏110的弯折部分具有形变恢复力，在该形变恢复力的作用下柔性屏110恢复展平状态且导致折叠装置200展开，而无法实现悬停。本申请实施例通过第一弹性件271驱动滑动件232a与配位件221之间抵接，在联动件230运动时产生阻尼。在用户撤去外力时，阻尼可以抵抗柔性屏110的该形变恢复力，能够确保折叠装置200在任意角度下的悬停，从而可以提高用户的使用手感。If the linkage 230 is not damped during movement (rotation and/or sliding), the linkage 230 may move under the action of any external force, resulting in the folding device 200 being unable to maintain the angle of use desired by the user, that is, unable to hover. , resulting in poor user experience. For example, when the user applies external force to fold the mobile phone, the flexible screen 110 on the mobile phone is deformed and folded and the folding device 200 is folded; when the user removes the external force, the bent part of the flexible screen 110 has a deformation restoring force. Under the action of the restoring force, the flexible screen 110 returns to the flat state and causes the folding device 200 to unfold, making it impossible to achieve hovering. In the embodiment of the present application, the first elastic member 271 drives the sliding member 232a to contact the fitting member 221 to generate damping when the linkage member 230 moves. When the user removes the external force, the damping can resist the deformation recovery force of the flexible screen 110 and ensure that the folding device 200 can hover at any angle, thus improving the user's feel.

另一些示例中，配位件221可以靠近或远离滑动件232a运动，第一弹性件271可以与配位件221连接，并通过驱动配位件221靠近滑动件232a运动，以使配位件221抵接在滑动件232a上。从而使得滑动件232a与配位件221之间产生阻尼，能够确保折叠装置200和电子设备在任意角度下的悬停。其中，第一弹性件271与配位件221可以直接连接，或者，通过其他结构部件间接连接。In other examples, the coordinating member 221 can move closer to or away from the sliding member 232a, and the first elastic member 271 can be connected with the coordinating member 221, and drive the coordinating member 221 to move closer to the sliding member 232a, so that the coordinating member 221 abutting on the slider 232a. As a result, damping is generated between the sliding member 232a and the coordinating member 221, which ensures that the folding device 200 and the electronic device can hover at any angle. The first elastic member 271 and the coordinating member 221 may be directly connected, or indirectly connected through other structural components.

其他一些示例中，滑动件232a可以靠近或远离配位件221运动，配位件221也可以靠近或远离滑动件232a运动，通过设置第一弹性件271使得滑动件232a和配位件221抵接，其原理已经阐述，不再赘述。In other examples, the sliding member 232a can move closer to or away from the coordinating member 221, and the coordinating member 221 can also move closer to or farther away from the sliding member 232a. The first elastic member 271 is provided so that the sliding member 232a and the coordinating member 221 abut. , its principle has been explained and will not be repeated.

示例性的，第一弹性件271可以为弹簧、弹片或者弹性材料制备的其他弹性件等。For example, the first elastic member 271 may be a spring, a spring piece, or other elastic member made of elastic material.

需要说明的是，在一些实施例中，可以通过精确控制滑动件232a和配位件221之间的装配位置，从而使得滑动件232a和配位件221之间紧密接触而抵接，但其装配难度较大。另外，由于制备及装配工艺存在误差，可能会导致滑动件232a和配位件221之间存在间隙而无法紧密接触，从而无法实现抵接的情况出现。通过设置第一弹性件271驱动滑动件232a和配位件221抵接，能够保证在折叠装置200在任意状态下均具有阻尼，保证折叠装置200在任意角度下的悬停，从而可以提高用户的使用手感。It should be noted that in some embodiments, the assembly position between the sliding member 232a and the coordinating member 221 can be precisely controlled so that the sliding member 232a and the coordinating member 221 are in close contact and abutted. More difficult. In addition, due to errors in the preparation and assembly process, there may be a gap between the sliding part 232a and the matching part 221, which prevents close contact, and thus abutment cannot be achieved. By arranging the first elastic member 271 to drive the sliding member 232a and the matching member 221 to contact, it can ensure that the folding device 200 has damping in any state and ensure that the folding device 200 can hover at any angle, thereby improving the user's comfort. Use feel.

In addition, the sliding arm 2324 can also be in contact with the second groove side wall 2232.

具体的，第二端232可以靠近或远离连接件220运动，因此滑动臂2324可以靠近或远离滑动槽223的槽内壁运动。例如，可以在滑动臂2324和槽顶壁2233之间设置呈压缩状态的第一弹性件271，第一弹性件271驱动滑动臂2324靠近第二槽底壁2234，以使滑动臂2324与第二槽底壁2234抵接，从而能够确保折叠装置200在任意角度下的悬停。Specifically, the second end 232 can move closer to or farther away from the connecting member 220 , so the sliding arm 2324 can move closer to or farther away from the inner wall of the sliding groove 223 . For example, a first elastic member 271 in a compressed state can be disposed between the sliding arm 2324 and the groove top wall 2233. The first elastic member 271 drives the sliding arm 2324 to approach the second groove bottom wall 2234, so that the sliding arm 2324 is in contact with the second groove bottom wall 2233.

示例性的，第一弹性件271可以呈压缩状态，第一弹性件271可以包括连接端和抵接端，连接端用于连接滑动件232a和第一配位槽222的槽内壁中的一者，抵接端用于抵接滑动件232a和第一配位槽222的槽内壁中的另一者。如图13所示，第一弹性件271的抵接端可以包括弹性抵接面261，滑动件232a和第一配位槽222的槽内壁中的被弹性抵接面261抵接的一者可以包括限位抵接面262，弹性抵接面261抵接于限位抵接面262上。例如，第一弹性件271可以与滑动件232a连接，并抵接于第一配位槽222的槽内壁；或者，第一弹性件271可以与第一配位槽222的槽内壁连接，并抵接于滑动件232a的外表面。For example, the first elastic member 271 may be in a compressed state, and the first elastic member 271 may include a connecting end and an abutting end. The connecting end is used to connect the sliding member 232a and one of the inner walls of the first coordination groove 222. , the abutting end is used to abut the other one of the sliding member 232a and the groove inner wall of the first coordination groove 222. As shown in FIG. 13 , the abutting end of the first elastic member 271 may include an elastic abutment surface 261 , and one of the sliding member 232 a and the inner wall of the first coordination groove 222 that is abutted by the elastic abutment surface 261 may It includes a limiting contact surface 262, and an elastic contact surface 261 is in contact with the limiting contact surface 262. For example, the first elastic member 271 can be connected with the sliding member 232a and abut against the inner wall of the first coordination groove 222; or, the first elastic member 271 can be connected with the inner wall of the first coordination groove 222 and abut against the inner wall of the first coordination groove 222. Connected to the outer surface of the sliding member 232a.

本申请实施例以第一弹性件271与滑动件232a连接，并抵接于第一配位槽222的槽内壁进行说明。The embodiment of the present application is explained with the first elastic member 271 connected to the sliding member 232a and abutting against the inner wall of the first coordination groove 222.

第一弹性件271可以位于滑动件232a和第一槽底壁2222(图12)之间，如图14所示，滑动件232a朝向第一槽底壁2222的一侧设置有容置槽2325，第一弹性件271可以设置于容置槽2325中，容置槽2325可以对第一弹性件271起到限位作用。一方面，如图12和图14所示，滑动件232a的滑动臂2324在第一弹性件271的作用下靠近槽顶壁2233，以使滑动臂2324与槽顶壁2233抵接，从而能够确保折叠装置200在任意角度下的悬停。另一方面，如图13所示，由于弹性抵接面261与限位抵接面262抵接，在折叠装置200的弯折过程中，弹性抵接面261与限位抵接面262相互滑动，从而可以在弹性抵接面261和限位抵接面262之间形成摩擦，可以进一步提高折叠装置200的阻尼，进一步保证折叠装置200在任意角度下的悬停。The first elastic member 271 may be located between the sliding member 232a and the first groove bottom wall 2222 (Fig. 12). As shown in Fig. 14, the sliding member 232a is provided with a receiving groove 2325 on one side facing the first groove bottom wall 2222. The first elastic member 271 can be disposed in the accommodating groove 2325, and the accommodating groove 2325 can play a limiting role on the first elastic member 271. On the one hand, as shown in Figures 12 and 14, the sliding arm 2324 of the sliding member 232a is close to the groove top wall 2233 under the action of the first elastic member 271, so that the sliding arm 2324 abuts the groove top wall 2233, thereby ensuring The folding device 200 hovers at any angle. On the other hand, as shown in FIG. 13 , since the elastic contact surface 261 is in contact with the limiting contact surface 262 , during the bending process of the folding device 200 , the elastic contact surface 261 and the limiting contact surface 262 slide against each other. , thus friction can be formed between the elastic contact surface 261 and the limiting contact surface 262, which can further improve the damping of the folding device 200 and further ensure the hovering of the folding device 200 at any angle.

示例性的，弹性抵接面261与限位抵接面262中的一者上设置有凸起部263(图14)，弹性抵接面261与限位抵接面262中的另一者上设置有凹陷部264(图12)。折叠装置200在展平状态或折叠状态时，凸起部263位于凹陷部264中。例如，图12和图14所示，凸起部263可以设置在弹性抵接面261上，凹陷部264可以设置在限位抵接面262上；或者，凸起部263可以设置在限位抵接面262上，凹陷部264可以设置在弹性抵接面261上。本申请实施例以凸起部263设置在弹性抵接面261上，凹陷部264设置在限位抵接面262上进行说明。Exemplarily, a protrusion 263 (Fig. 14) is provided on one of the elastic abutment surface 261 and the limit abutment surface 262, and the other of the elastic abutment surface 261 and the limit abutment surface 262 is provided with a protrusion 263 (Fig. 14). A recess 264 is provided (Fig. 12). When the folding device 200 is in the flat state or the folded state, the protruding portion 263 is located in the recessed portion 264 . For example, as shown in Figures 12 and 14, the protruding portion 263 can be provided on the elastic contact surface 261, and the recessed portion 264 can be provided on the limiting contact surface 262; or, the protruding portion 263 can be provided on the limiting contact surface 262. On the joint surface 262, the recessed portion 264 may be provided on the elastic abutment surface 261. The embodiment of the present application will be described by assuming that the protruding portion 263 is provided on the elastic contact surface 261 and the recessed portion 264 is provided on the limiting contact surface 262 .

需要说明的是，当凸起部263位于凹陷部264之外并朝向凹陷部2***，凸起部263到达凹陷部264边缘时，在弹性抵接面261与限位抵接面262的相互弹性挤压作用力下，凸起部263会自动进入到凹陷部264中，从而使得折叠装置200进入展平状态或折叠状态时的手感较为顺滑。当凸起部263进入凹陷部264中时，用户能感觉到明显的停顿感，凸起部263和凹陷部264相互可以起到限位的作用，使得折叠装置200可以稳定保持在折叠状态或展平状态。另外，当凸起部263位于凹陷部264中时，第一弹性件271的形变程度减小，凸起部263与凹陷部264之间的相互作用力减小，可以减小对弹性抵接面261与限位抵接面262的挤压，从而对弹性抵接面261与限位抵接面262起到保护作用。It should be noted that when the protruding portion 263 is located outside the recessed portion 264 and moves toward the recessed portion 264, and when the protruding portion 263 reaches the edge of the recessed portion 264, the mutual elasticity of the elastic contact surface 261 and the limiting contact surface 262 Under the squeezing force, the protruding portion 263 will automatically enter the recessed portion 264, so that the folding device 200 feels smoother when it enters the flattened state or the folded state. When the protruding portion 263 enters the recessed portion 264, the user can feel an obvious sense of pause. The protruding portion 263 and the recessed portion 264 can limit each other, so that the folding device 200 can be stably maintained in the folded state or unfolded. flat state. In addition, when the protruding portion 263 is located in the recessed portion 264, the deformation degree of the first elastic member 271 is reduced, the interaction force between the protruding portion 263 and the recessed portion 264 is reduced, and the resistance to the elastic contact surface can be reduced. 261 and the limiting contact surface 262, thereby protecting the elastic contact surface 261 and the limiting contact surface 262.

如图15所示，凹陷部264包括间隔设置的第一凹陷部2641和第二凹陷部2642。折叠装置200在展平状态时，凸起部263位于第一凹陷部2641；从而使得折叠装置200进入展平状态时的手感较为顺滑，凸起部263与第一凹陷部2641之间的相互作用力较小，对弹性抵接面261与限位抵接面262起到保护作用；另外，还有利于保持折叠装置200的展平状态。As shown in FIG. 15 , the recessed portion 264 includes a first recessed portion 2641 and a second recessed portion 2642 that are spaced apart. When the folding device 200 is in the flattened state, the raised portion 263 is located in the first recessed portion 2641; thus, the folding device 200 has a smoother feel when it enters the flattened state, and the interaction between the raised portion 263 and the first recessed portion 2641 is smooth. The acting force is small, which protects the elastic contact surface 261 and the limiting contact surface 262; in addition, it is also helpful to maintain the flattened state of the folding device 200.

继续参考图16，折叠装置200在折叠状态时，凸起部263位于第二凹陷部2642中；从而使得折叠装置200进入折叠状态时的手感较为顺滑，凸起部263与第二凹陷部2642之间的相互作用力较小，对弹性抵接面261与限位抵接面262起到保护作用；另外，还有利于保持折叠装置200的折叠状态。Continuing to refer to Figure 16, when the folding device 200 is in the folded state, the raised portion 263 is located in the second recessed portion 2642; thus, the folding device 200 feels smoother when it enters the folded state. The raised portion 263 and the second recessed portion 2642 The interaction force between The elastic contact surface 261 and the limiting contact surface 262 play a protective role; in addition, they are also beneficial to maintaining the folded state of the folding device 200 .

需要说明的是，凸起部263在第一凹陷部2641和第二凹陷部2642之外时，凸起部263抵接在第一凹陷部2641和第二凹陷部2642之间的区域，第一弹性件271的形变程度变大，弹性抵接面261与限位抵接面262之间抵接力变大，从而使得滑动件232a与槽顶壁2233(图12)之间的抵接力较大，以提高折叠装置200的阻尼，更好的保证折叠装置200的悬停效果。It should be noted that when the protruding portion 263 is outside the first recessed portion 2641 and the second recessed portion 2642, the protruding portion 263 abuts the area between the first recessed portion 2641 and the second recessed portion 2642. The first The degree of deformation of the elastic member 271 becomes larger, and the contact force between the elastic contact surface 261 and the limiting contact surface 262 becomes larger, so that the contact force between the sliding member 232a and the groove top wall 2233 (Fig. 12) becomes larger. In order to improve the damping of the folding device 200, the hovering effect of the folding device 200 can be better ensured.

当然的，凹陷部264还可以包括第三凹陷部，第三凹陷部可以位于第一凹陷部2641与第二凹陷部2642之间，从而有利于折叠装置200稳定的保持在中间状态的同时对弹性抵接面261与限位抵接面262起到保护作用。Of course, the recessed part 264 may also include a third recessed part, and the third recessed part may be located between the first recessed part 2641 and the second recessed part 2642, thereby facilitating the folding device 200 to be stably maintained in the intermediate state while improving elasticity. The contact surface 261 and the limiting contact surface 262 play a protective role.

滑动件232a与配位件221的第二种实施方式中，如图17-图18所示，第一配位槽222开设在配位件221中，第一配位槽222可以沿铰链组件210的轴向贯穿配位件221，滑动件232a位于第一配位槽222外，且与配位件221的外壁面抵接。折叠装置200还可以包括插接件225，插接件225插设在第一配位槽222和滑动件232a中，插接件225沿第一配位槽222滑动，滑动件232a通过插接件225与第一配位槽222滑动连接。当连接件220相对铰链组件210转动时，带动联动件230相对铰链组件210转动，且联动件230带动插接件225沿第一配位槽222的延伸方向滑动。插接件225在滑动件232a的带动下沿第一配位槽222滑动，从而实现滑动件232a与第一配位槽222之间的滑动。In the second embodiment of the sliding part 232a and the coordinating part 221, as shown in Figures 17 and 18, the first coordinating groove 222 is opened in the coordinating part 221, and the first coordinating groove 222 can be along the hinge assembly 210 The sliding member 232a is located outside the first coordinating groove 222 and contacts the outer wall surface of the coordinating member 221. The folding device 200 may also include a plug-in connector 225. The plug-in connector 225 is inserted into the first coordinating slot 222 and the sliding member 232a. The plug-in connector 225 slides along the first coordinating slot 222, and the sliding member 232a passes through the plug-in connector. 225 is slidingly connected to the first coordination groove 222.

For example, the first end 231 may include a first rotating part 2311 and a second rotating part 2312 that are spaced apart. The first mounting part 2131 is located between the first rotating part 2311 and the second rotating part 2312. The first rotating part 2311 is located between the first rotating part 2311 and the second rotating part 2312. Between a mounting part 2131 and the first contact part 211, the first rotating part 2311 is in contact with the first contact part 211. The second elastic member 272 can sequentially drive the first contact member 211 and the first rotating part 2311 to approach the first mounting part 2131, so that the first rotating part 2311 abuts the first mounting part 2131. Both sides of the first rotating part 2311 along the axial direction of the hinge assembly 210 are respectively in contact with the first contact member 211 and the first mounting member 2131. That is, the first end surface 2331 is in contact with the first contact member 211. The surface of the portion 2311 away from the first end surface 2331 is in contact with the first mounting member 2131. The contact area of the first rotating portion 2311 is larger, thereby better ensuring the hovering effect of the folding device 200.

以下对本申请实施例提供的第一端231的至少部分与第一安装件2131之间具有间隙进行说明。The following describes the gap between at least part of the first end 231 and the first mounting member 2131 provided in the embodiment of the present application.

一些示例中，如图23所示，沿铰链组件210的轴向，铰链组件210上还设置有第二抵接件212，第二抵接件212位于第一端231远离第一抵接件211的一侧，第一端231位于第一抵接件211与第二抵接件212之间，第一端231的沿铰链组件210的轴向的相对两侧分别与第一抵接件211与第二抵接件212抵接。第一端231被抵接的面积较大，从而可以较好的保证折叠装置200的悬停效果。其中，第一端231可以包括第一转动部2311和第二转动部2312，其原理已经阐述，不再赘述。第一转动部2311与第一安装件2131之间具有间隙，第二弹性件272可以依次驱动第一抵接件211、第一转动部2311和第二转动部2312靠近第二抵接件212，使得第一转动部2311与第一抵接件211抵接，且第二转动部2312与第二抵接件212抵接。即第一端面2331与第一抵接件211抵接，第二端面2332与第二抵接件212抵接，从而能够确保折叠装置200在任意角度下的悬停。In some examples, as shown in FIG. 23 , along the axial direction of the hinge assembly 210 , a second contact member 212 is also provided on the hinge assembly 210 . The second contact member 212 is located at the first end 231 away from the first contact member 211 On one side of the hinge assembly 210 , the first end 231 is located between the first contact member 211 and the second contact member 212 . The opposite sides of the first end 231 along the axial direction of the hinge assembly 210 are respectively connected with the first contact member 211 and the second contact member 212 . The second contact piece 212 is in contact. The area where the first end 231 is contacted is larger, thereby better ensuring the hovering effect of the folding device 200 . The first end 231 may include a first rotating part 2311 and a second rotating part 2312. The principles thereof have been explained and will not be described again. There is a gap between the first rotating part 2311 and the first mounting part 2131. The second elastic member 272 can sequentially drive the first contacting part 211, the first rotating part 2311 and the second rotating part 2312 to approach the second contacting part 212. The first rotating part 2311 is in contact with the first contact member 211 , and the second rotating part 2312 is in contact with the second contact member 212 . That is, the first end surface 2331 is in contact with the first contact member 211, and the second end surface 2332 is in contact with the second contact member 212, thereby ensuring that the folding device 200 can hover at any angle.

需要说明的是，若第一转动部2311与第一安装件2131之间没有间隙，则可能导致第一转动部2311先与第一安装件2131之间抵接，而导致第二转动部2312与第二抵接件212之间无法抵接。因此，第一安装件2131与第一转动部2311之间间隔设置，可以避免第一安装件2131影响第二抵接件212与第二转动部2312抵接。It should be noted that if there is no gap between the first rotating part 2311 and the first mounting part 2131, it may cause the first rotating part 2311 to contact the first mounting part 2131 first, causing the second rotating part 2312 to contact with the first mounting part 2131. The second contact parts 212 cannot contact each other. Therefore, the first mounting part 2131 and the first rotating part 2311 are spaced apart, which can prevent the first mounting part 2131 from affecting the contact between the second contacting part 212 and the second rotating part 2312.

另一些示例中，如图21所示，第一端231与第一抵接件211抵接，位于第一抵接件211和第一安装件2131之间的第一端231与第一安装件2131之间具有间隙，联动件230的第二端232可以与连接件220抵接。第二弹性件272依次驱动第一抵接件211和联动件230靠近连接件220，使得第一端231的第一端面2331(图22)与第一抵接件211抵接，第二端232的第二端面2332(图22)与连接件220抵接，从而能够确保折叠装置200在任意角度下的悬停。例如，在配位件221设置在连接件220的实施方式中，第二端232的第二端面2332可以与配位件221的外壁面或者配位件221中的第一配位槽222的槽内壁抵接。其中，可以是第一端231的全部均位于第一抵接件211和第一安装件2131之间，第一端231与第一安装件2131之间具有间隙。或者，第一端231可以包括第一转动部2311和第二转动部2312，第一转动部2311位于第一抵接件211和第一安装件2131之间，第一转动部2311与第一安装件 2131之间具有间隙。In other examples, as shown in FIG. 21 , the first end 231 is in contact with the first contact member 211 , and the first end 231 located between the first contact member 211 and the first mounting member 2131 is in contact with the first mounting member 2131 . There is a gap between 2131 and the second end 232 of the linkage member 230 can be in contact with the connecting member 220 . The second elastic member 272 drives the first contact member 211 and the linkage member 230 to approach the connector 220 in sequence, so that the first end surface 2331 (Fig. 22) of the first end 231 contacts the first contact member 211, and the second end 232 The second end surface 2332 (Fig. 22) is in contact with the connecting member 220, thereby ensuring the hovering of the folding device 200 at any angle. For example, in an embodiment in which the fitting member 221 is disposed on the connecting member 220 , the second end surface 2332 of the second end 232 may be in contact with the outer wall surface of the fitting piece 221 or the groove of the first fitting groove 222 in the fitting piece 221 . Inner wall abutment. Wherein, the entire first end 231 may be located between the first contact member 211 and the first mounting member 2131, and there is a gap between the first end 231 and the first mounting member 2131. Alternatively, the first end 231 may include a first rotating part 2311 and a second rotating part 2312. The first rotating part 2311 is located between the first abutting part 211 and the first mounting part 2131. The first rotating part 2311 is connected to the first mounting part 2311 . pieces There is a gap between 2131.
