The following describes a rotating structure and an electronic device according to an embodiment of the present application with reference to fig. 1 to 8, respectively.

As shown in fig. 1 to 5, according to some embodiments of the present application, the rotating structure 1 is applied to a foldable electronic device and includes at least one first rotating shaft assembly 10, and the first rotating shaft assembly 10 includes: a first rotating shaft 103, a first rotating rod 101, a second rotating rod 102 and a driving assembly 104; the first rotating rod 101 and the second rotating rod 102 are respectively arranged at two sides of the axis of the first rotating shaft 103, one end of each of the first rotating rod 101 and the second rotating rod 102 is rotatably connected with the first rotating shaft 103, and one end of the first rotating rod 101 is in contact connection with the opposite end face of one end of the second rotating rod 102; the driving assembly 104 is connected to the first rotating rod 101 and/or the second rotating rod 102, and is configured to control a contact friction force between the first rotating rod 101 and the second rotating rod 102, so as to switch a magnitude of the contact friction force between zero and a first preset value, where the first preset value is greater than zero.

Specifically, in the present embodiment, by providing the rotating structure 1 applied to the foldable electronic device, the first rotating rod 101 and the second rotating rod 102 capable of rotating relative to the first rotating shaft 103 are disposed on the rotating structure 1, and the driving assembly 104 controls the contact friction force between the two rotating rods, when the electronic device is automatically or manually controlled to be opened or closed, the contact friction force between the first rotating rod 101 and the second rotating rod 102 can be controlled to be zero, when the folding main body on the electronic device reaches a desired operating angle, the contact friction force between the first rotating rod 101 and the second rotating rod 102 can be controlled to maintain a first preset value, so that the folding main body on the electronic device reaches a desired hovering angle of a user, and simultaneously, when the electronic device is manually controlled to be opened or closed, the contact friction force between the first rotating rod 101 and the second rotating rod 102 can be controlled to maintain the first preset value, make operating personnel have certain operation and feel, make folding main part on the electronic equipment reach the required angle of hovering of user equally to be convenient for the user to folded cascade electronic equipment's operation use, promoted user experience.

In a specific application process, the rotating structure 1 shown in this embodiment can be used in a foldable electronic device having two foldable main bodies, the first rotating rod 101 is connected to one of the foldable main bodies of the electronic device, and the second rotating rod 102 is connected to the other foldable main body of the electronic device, so that when the electronic device is automatically or manually driven to perform a folding operation, the two foldable main bodies of the electronic device can be controlled to rotate in the opposite direction or in the opposite direction with respect to the rotation center of the rotating structure 1. Therein, the rotating structure 1 shown in the present embodiment can also be used for a folding body, for example, a flexible screen known in the art. Here, the rotating shaft structure may be directly installed on the back surface of the flexible screen to control the opening and closing of the flexible screen.

It should be noted that, in the embodiment, the first rotating shaft 103 is fixedly disposed along the rotation center of the rotating structure 1, and two ends of the first rotating shaft 103 can be respectively mounted on the rotating structure 1 through a fixing seat. The driving assembly 104 shown in the present embodiment may be understood as a telescopic driving mechanism that can be connected to one of the first rotating rod 101 and the second rotating rod 102 to control the magnitude of the contact friction force between the first rotating rod 101 and the second rotating rod 102, such as an electric push rod or a linear motor known in the art, or may be understood as a clamping mechanism that can be connected to both the first rotating rod 101 and the second rotating rod 102 to control the magnitude of the contact friction force between the first rotating rod 101 and the second rotating rod 102, and is not limited thereto.

Meanwhile, when the friction force between the first rotating rod 101 and the second rotating rod 102 shown in this embodiment reaches the first preset value, one end of the first rotating rod 101 abuts against one end of the second rotating rod 102, and when the first rotating rod 101 and the second rotating rod 102 abut against each other, a large contact friction force exists between the first rotating rod 101 and the second rotating rod 102, so that the first rotating rod 101 and the second rotating rod 102 can keep relatively stationary and can bear a large torsion force, and cannot rotate relative to the first rotating shaft 103, that is, an included angle between the first rotating rod 101 and the second rotating rod 102 when the first rotating rod 101 and the second rotating rod 102 abut against each other is ensured to be kept unchanged.

When the friction force between the first rotating rod 101 and the second rotating rod 102 is zero, there is no interaction force between the first rotating rod 101 and the second rotating rod 102, and in this state, the hovering angle required by the user cannot be maintained between the first rotating rod 101 and the second rotating rod 102, but it is convenient to control the first rotating rod 101 and the second rotating rod 102 to rotate relative to the first rotating shaft 103.

Therefore, the first preset value can be understood as one or more values larger than zero, and the first preset value is specifically the minimum contact friction value required when the folding main body of the electronic device can reach the hovering angle required by the user.

As shown in fig. 4, in the present embodiment, a fixed position where one end of the first rotating rod 101 is rotatably installed on the first rotating shaft 103 is specifically provided, a driving end of the driving assembly 104 is connected with one end of the second rotating rod 102, and the driving assembly 104 applies a driving force to one end of the second rotating rod 102 toward one side of the first rotating rod 101 to control a contact friction force between the first rotating rod 101 and the second rotating rod 102.

Alternatively, in this embodiment, one end of the second rotating rod 102 is rotatably installed at a fixed position on the first rotating shaft 103, the driving end of the driving assembly 104 is connected to one end of the first rotating rod 101, and the driving assembly 104 applies a driving force to one end of the first rotating rod 101 towards one side of the second rotating rod 102 to control the contact friction force between the first rotating rod 101 and the second rotating rod 102.

Alternatively, the output end of the driving assembly 104 shown in this embodiment is connected to both one end of the first rotating rod 101 and one end of the second rotating rod 102, and the driving assembly 104 can apply opposite acting forces to the one end of the first rotating rod 101 and the one end of the second rotating rod 102 to control the contact friction force between the first rotating rod 101 and the second rotating rod 102.

Further, the driving assembly 104 of the present embodiment includes a slider 1041 and a linear driving mechanism; the sliding block 1041 is slidably mounted on the first rotating shaft 103, and the sliding block 1041 and the first rotating rod 101 are respectively arranged at two sides of the second rotating rod 102; the driving end of the linear driving mechanism is connected to the slider 1041 to drive the slider 1041 to reciprocate along the axis of the first rotating shaft 103, and the contact friction force between the first rotating rod 101 and the second rotating rod 102 is controlled by the slider 1041.

Specifically, in this embodiment, a shaft hole adapted to the first rotating shaft 103 may be formed in the sliding block 1041, and the sliding block 1041 is sleeved on the first rotating shaft 103 through the shaft hole, so that the sliding block 1041 can reciprocate along an axis of the first rotating shaft 103. Meanwhile, the linear driving mechanism shown in the present embodiment may be an electric push rod, a linear motor, etc. known in the art, and may not be particularly limited herein.

As shown in fig. 2 to 4, in the case that one end of the first rotating rod 101 is rotatably mounted at a fixed position on the first rotating rod 103, when the driving slider 1041 moves toward the first rotating rod 101, the driving force toward one side of the first rotating rod 101 can be applied to the second rotating rod 102 by the slider 1041, so that one end of the second rotating rod 102 abuts against one end of the first rotating rod 101; when the driving end of the linear driving mechanism drives the slider 1041 away from the first rotating rod 101, since the slider 1041 no longer applies the driving force toward the first rotating rod 101 to the second rotating rod 102, the contact friction force between one end of the second rotating rod 102 and one end of the first rotating rod 101 is zero due to lack of the interaction force.

Further, in order to increase an adjustable space of the linear driving mechanism, and ensure that the linear driving mechanism applies a driving force to the slider 1041 better, and avoid the slider 1041 from being directly in rigid contact with the second rotating rod 102 to damage the second rotating rod 102, the driving assembly 104 shown in this embodiment is further provided with an elastic member 1043, the elastic member 1043 is disposed between the slider 1041 and the second rotating rod 102, the linear driving mechanism can drive the slider 1041 to move between the first position and the second position on the first rotating rod 103, and the elastic member 1043 is in a compressed state when the slider 1041 is located at the first position, and is in a reset state when the slider 1041 is located at the second position.

As shown in fig. 4, in order to control the sliding block 1041 to stably move between the first position and the second position on the first rotating shaft 103, the linear driving mechanism shown in this embodiment includes a first motor 1042, the first motor 1042 may be a stepping motor known in the art, an external thread is disposed on an output shaft of the first motor 1042, a threaded hole is disposed on the sliding block 1041, and the output shaft of the first motor 1042 is in threaded fit with the threaded hole. Since the axis of the first motor 1042 is parallel to the axis of the first rotating shaft 103, and the slider 1041 can only move along the axis of the first rotating shaft 103, the slider 1041 can be driven to move between the first position and the second position on the first rotating shaft 103 by controlling the forward and reverse rotation of the first motor 1042.

As shown in fig. 4, in a case that one end of the first rotating rod 101 is rotatably mounted at a fixed position on the first rotating shaft 103, the elastic member 1043 shown in this embodiment is disposed between the slider 1041 and the first rotating rod 101, wherein the elastic member 1043 shown in this embodiment includes a spring or an elastic sheet; in the case that the elastic member 1043 is a spring, the spring may be directly sleeved on the first rotating shaft 103; in the case that the elastic member 1043 is a spring, a ring structure may be disposed at both ends of the spring to sleeve the spring on the first rotating shaft 103.

Meanwhile, the first position shown in this embodiment is the P1 position shown in fig. 4, the second position shown in this embodiment is the P2 position shown in fig. 3, and the P1 position and the P2 position are spaced along the axis of the first rotating shaft 103. Since the elastic member 1043 is in a compressed state when the slider 1041 is located at the position P1, when the first motor 1042 rotates forward to drive the slider 1041 to reach the position P1, the slider 1041 can apply a driving force to the second rotating rod 102 through the elastic member 1043, so that the first rotating rod 101 abuts against the second rotating rod 102; accordingly, since the elastic member 1043 is in the reset state when the slider 1041 is located at the position P2, when the first motor 1042 rotates in the reverse direction to drive the slider 1041 to reach the position P2, the slider 1041 no longer applies a driving force to the elastic member 1043, and the contact friction force between the one end of the second rotating rod 102 and the one end of the first rotating rod 101 is zero due to the lack of interaction force therebetween.

It can be seen that the contact friction force between the first rotating rod 101 and the second rotating rod 102 can be better controlled by providing the elastic member 1043 in the driving assembly 104.

When the rotating structure 1 shown in this embodiment is applied to a foldable electronic device, the operating state of the linear driving mechanism can be set by the electronic device, and the P1 position that can be reached by the slider 1041 can be adjusted to adjust the compression state of the elastic member 1043, so as to adjust the contact friction force when the first rotating rod 101 abuts against the second rotating rod 102, thereby controlling the torque force required when the electronic device is manually opened or closed.

As shown in fig. 4, in order to ensure that when one end of the first rotating rod 101 abuts against one end of the second rotating rod 102, there is a large contact friction force therebetween, so as to enhance the hovering effect of the foldable electronic device, the driving assembly 104 shown in this embodiment further includes a damping member 1044, the damping member 1044 is mounted on the first rotating shaft 103 between the first rotating rod 101 and the second rotating rod 102, and the damping member 1044 has a first damping surface contacting one end of the first rotating rod 101 and a second damping surface contacting one end of the second rotating rod 102.

Alternatively, the present embodiment may fixedly mount the damping member 1044 on the first rotating shaft 103 between the first rotating shaft 101 and the second rotating shaft 102. When the driving assembly 104 applies a driving force to the second rotating rod 102 toward one side of the first rotating rod 101, one end of the first rotating rod 101 may abut against the first damping surface on the damping member 1044, and one end of the second rotating rod 102 may abut against the second damping surface on the damping member 1044.

Alternatively, in the present embodiment, the damping member 1044 can be slidably mounted on the first rotating shaft 103 along the axis of the first rotating shaft 103, and the damping member 1044 is disposed between the first rotating rod 101 and the second rotating rod 102, wherein the damping member 1044 can be specifically designed as a round sleeve structure, and the damping member 1044 is directly sleeved on the first rotating shaft 103.

Alternatively, at least one of the opposite end surfaces of one end of the first rotating lever 101 and one end of the second rotating lever 102 shown in the present embodiment is formed as a damping surface.

Specifically, in this embodiment, an end surface of the first rotating rod 101 facing the second rotating rod 102 may be a damping surface, and an end surface of the second rotating rod 102 facing the first rotating rod 101 may be a smooth surface; in this embodiment, an end surface of the first rotating rod 101 facing the second rotating rod 102 may also be a smooth surface, and an end surface of the second rotating rod 102 facing the first rotating rod 101 may be a damping surface; in this embodiment, the end surfaces of the first rotating rod 101 opposite to the end surface of the second rotating rod 102 may be damping surfaces.

Thus, in the case where the damping member 1044 is not provided, the driving assembly 104 of the present embodiment can drive one end of the first rotating rod 101 to directly abut against one end of the second rotating rod 102 by the first motor 1042; when the damping member 1044 is disposed, the driving assembly 104 can also realize the abutting of the first rotating rod 101 and the second rotating rod 102 under the cooperation of the damping member 1044, so that the first rotating rod 101 and the second rotating rod 102 can be ensured to bear a large torsion force based on the damping effect between the first rotating rod 101 and the second rotating rod 102 or between any one of the first rotating rod 101 and the second rotating rod 102 and the damping member 1044.

As shown in fig. 2, 3 and 5, the rotation structure 1 of the present embodiment further includes at least one second rotation shaft assembly 11, where the second rotation shaft assembly 11 includes: a second rotating shaft 113, a first rotating arm 111, a second rotating arm 112, and a driving mechanism 114; the second rotating shaft 113 is arranged in the same direction as the first rotating shaft 103; one end of each of the first rotating arm 111 and the second rotating arm 112 is rotatably connected with the second rotating shaft 113, and the first rotating arm 111 and the second rotating arm 112 are in power coupling connection; the driving mechanism 114 is used for driving the first rotating arm 111 and the second rotating arm 112 to synchronously rotate in opposite directions or rotate in opposite directions.

Specifically, the second rotating shaft assembly 11 shown in this embodiment is provided with the first rotating arm 111, the second rotating arm 112 and the driving mechanism 114, and the driving mechanism 114 drives the first rotating arm 111 and the second rotating arm 112 to synchronously rotate in opposite directions or rotate in opposite directions, so that when the rotating structure 1 shown in this embodiment is applied to a foldable electronic device, the first rotating arm 111 can be connected to one of the foldable main bodies of the electronic device, and the second rotating arm 112 can be connected to the other foldable main body of the electronic device, so that the driving mechanism 114 can drive the two foldable main bodies of the electronic device to synchronously rotate in opposite directions or rotate in opposite directions, thereby realizing automatic folding of the electronic device, and in the process of performing automatic folding control on the electronic device, the first rotating shaft assembly 10 shown in the above embodiment can be combined to control the two foldable main bodies on the electronic device to reach a hovering angle required by a user, therefore, the technological sense of the electronic equipment is enhanced, and better user experience is brought.

Meanwhile, based on automatic folding control over the electronic equipment, manual folding operation of operators on the electronic equipment can be reduced, and damage to the screen of the electronic equipment due to improper manual operation of the operators is prevented, so that effective protection on the screen of the electronic equipment is achieved, and the service life of the electronic equipment is prolonged.
