Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0087] See Figures 1-16This application provides an electronic device that may include a first body 100, a second body 200, and a connecting device 300. The first body 100 may have a display screen 110, and the connecting device 300 can connect the first body 100 and the second body 200 to enable relative rotation between them. The electronic device can be of various types, such as a laptop computer, a mobile phone, or a desktop computer; this application does not limit this type. The accompanying drawings use a laptop computer as an example to illustrate the electronic device. The first body 100 and the second body 200 of the electronic device are connected by the connecting device 300 and can rotate relative to each other based on the connecting device 300, thereby changing the orientation of the display screen 110 on the first body 100. Figure 1 In the exemplary embodiment shown, the second body 200 may be the host portion of an electronic device. Of course, in other embodiments, the second body 200 may be in other forms, such as a bracket or base supporting the first body 100. That is, the second body 200 may be a component equipped with electronic components or a component without electronic components, and this application does not limit it in this regard.

[0088] The connecting device 300 may include a first rotating shaft assembly 310, which may include a first rotating shaft 311 connecting the first body 100 and the second body 200, a first driving member 313 capable of providing a first driving force to the first rotating shaft 311, and a transmission mechanism for transmitting the first driving force to the first rotating shaft 311. The first driving member 313 is a power component installed in the electronic device, and the power source of the first driving member 313 may be of various types such as electrical energy, hydraulic energy, or pneumatic energy. The transmission mechanism is connected between the first rotating shaft 311 and the first driving member 313, and can play the role of transmitting power and changing the form of motion. That is, while transmitting the force, the transmission mechanism can also convert the initial form of motion provided by the first driving member 313 (for example, linear motion or rotational motion) into the rotational motion relative to the second body 200 required by the first body 100.

[0089] The transmission mechanism can be configured with different frictional forces between itself and the first rotating shaft 311 and the second body 200, so that the first rotating shaft assembly 310 can support the first body 100 to rotate relative to the second body 200 in a first direction under the action of a first driving force or a second driving force, the second driving force being the force applied to the first body 100 by the user. That is, the transmission mechanism can be configured to have frictional forces with the first rotating shaft 311 and the second body 200 respectively, but the magnitude of the torque generated by the frictional forces on the first body 100 is different, so that the first body 100 can rotate relative to the second body 200 under the action of the second driving force provided by the user, and can also rotate relative to the second body 200 under the action of the first driving force provided by the first driving member 313. In this way, when using the electronic device, the user can choose to apply force directly to the first body 100 by hand to make the first body 100 rotate relative to the second body 200, or choose a non-manual method, where the first driving member 313 drives the first body 100 to rotate relative to the second body 200. The user's hands can be freed up to rest, save energy, or do other things, improving work efficiency.

[0090] In some embodiments, the transmission mechanism may include a first transmission member 317, which has a first frictional force with a first rotating shaft 311 and a second frictional force with a second body 200. That is, the first transmission member 317 is in contact with both the first rotating shaft 311 and the second body 200. The contact between the first transmission member 317 and the second body 200 can generate a second frictional force that hinders the movement of the first transmission member 317 relative to the second body 200. The contact between the first transmission member 317 and the first rotating shaft 311 can generate a first frictional force that either drives (e.g., the process of the first body 100 moving relative to the second body 200 under the action of a first driving force) the first rotating shaft 311 to move relative to the second body 200 or hinders (e.g., the process of the first body 100 moving relative to the second body 200 under the action of a second driving force) the first rotating shaft 311 to move relative to the first transmission member 317.

[0091] The first and second friction forces are configured to satisfy the condition that the second friction force is greater than the first friction force, enabling the first rotating shaft assembly 310 to support the first body 100 to rotate relative to the second body 200 in a first direction under the action of the first driving force or the second driving force. The first direction may include a torsional direction T or an opening / closing direction K. The rotation of the first body 100 relative to the second body 200 in the opening / closing direction K refers to a rotation that changes the angle between the first body 100 and the second body 200. For example, in an application scenario where an electronic device is placed on a desktop, the first body 100 rotates vertically relative to the second body 200 along the opening / closing direction K, which can increase or decrease the angle between the first body 100 and the second body 200, thereby providing the user with a more comfortable viewing angle for the screen. The rotation of the first body 100 relative to the second body 200 in the torsional direction T refers to a rotation that satisfies the perpendicular condition to the rotation in the opening / closing direction K. That is, the plane of rotation formed by the rotation of the first body 100 relative to the second body 200 in the torsional direction T is perpendicular to the plane of rotation in the opening / closing direction K. In other words, the axis of rotation of the first body 100 relative to the second body 200 in the torsional direction T is perpendicular to the axis of rotation in the opening / closing direction K. For example, in an application scenario where the electronic device is placed on a desktop, with the first body 100 and the second body 200 opened to 90 degrees, a horizontal rotation of the first body 100 relative to the second body 200 along the torsional direction T can cause the orientation of the display screen 110 to shift to the left or right of the user.

[0092] The second frictional force being greater than the first frictional force means that the torque generated by the second frictional force on the first body 100 is greater than the torque generated by the first frictional force on the first body 100. When the first body 100 is driven to rotate relative to the second body 200 by the first driving member 313, the driving force of the first driving member 313 is transmitted to the first transmission member 317 and can overcome the second frictional force, causing the first transmission member 317 to rotate relative to the second body 200. The rotating first transmission member 317 drives the first rotating shaft 311 to move with the help of the first frictional force, thereby causing the first body 100 to rotate relative to the second body 200. However, when the user manually drives the first body 100 to rotate relative to the second body 200, although the rotating first body 100 drives the first rotating shaft 311 to move, because the first frictional force is less than the second frictional force, that is, the force between the first rotating shaft 311 and the first transmission member 317 is insufficient to overcome the force of the second body 200 that hinders the movement of the first transmission member 317, the moving first rotating shaft 311 cannot drive the first transmission member 317 to move.

[0093] In some embodiments, the electronic device can be configured such that the first body 100 can rotate relative to the second body 200 under the combined action of a first driving force and a second driving force. That is, during the process of the user manually driving the first body 100 to rotate relative to the second body 200, the first driving member 313 can be in an active state, and the first transmission member 317 moves relative to the second body 200 under the drive of the first driving member 313. With this configuration, the rotation of the first body 100 relative to the second body 200 can be achieved in three ways. For example, when the first driving member 313 is used to rotate the first body 100 relative to the second body 200 in the torsional direction T, the rotation of the first body 100 relative to the second body 200 in the torsional direction T can be achieved in three ways: first, the first driving member 313 is in a non-active state, and the user manually rotates the first body 100; second, the user does not apply any force to the first body 100, and the first driving member 313 works to automatically rotate the first body 100; third, while the first driving member 313 is working, the user applies a force to the first body 100, which together rotates the first body 100. For example, when the first driving member 313 is used to rotate the first body 100 relative to the second body 200 in the opening and closing direction K, the rotation of the first body 100 relative to the second body 200 in the opening and closing direction K can be achieved in three ways: the first is that the first driving member 313 is in a non-working state, and the user manually opens or closes the first body 100; the second is that the user does not apply any force to the first body 100, and the first driving member 313 works to make the first body 100 open or close automatically; the third is that while the first driving member 313 is working, the user applies a force to the first body 100, which together makes the first body 100 open or close.

[0094] In some embodiments, the connecting device 300 can be configured to enable relative rotation of the first body 100 and the second body 200 in two different directions. That is, the connecting device 300 can simultaneously provide two rotation axes as rotation center lines for the relative rotation of the first body 100 and the second body 200. These two rotation axes do not satisfy the parallel condition. The relative rotation of the first body 100 and the second body 200 based on the connecting device 300 can be relative rotation about one of the rotation axes or relative rotation about the other rotation axis. For example, the connecting device 300 can be configured to enable relative rotation of the first body 100 and the second body 200 in the opening / closing direction K and relative rotation in the torsional direction T. The first body 100 can not only perform opening / closing rotation but also torsional rotation. With this configuration, the display screen 110 of the electronic device can adjust its angle in more directions, thereby meeting more diverse user needs. Taking the application scenario where the electronic device is placed on a horizontal table as an example, the first body 100 can not only adjust the pitch angle of the display screen 110 by vertical movement but also move horizontally to orient the display screen 110 towards users in different directions.

[0095] In some embodiments, the electronic device can be configured such that, during the rotation of the first body 100 relative to the second body 200 driven by the first driving member 313, the electronic device can also adjust the operating parameters of the first driving member 313 based on the second driving force. That is, the operating parameters of the first driving member 313 can respond to changes in the force applied by the user to the first body 100. For example, a sensor can be electrically connected to a controller (e.g., an EC chip, an AI chip, or other form of microcontroller) capable of controlling the operation of the first driving member 313. The controller detects the magnitude and / or direction of the second driving force through the sensor, thereby adjusting the operating parameters of the first driving member 313 according to the second driving force. The operating parameters of the first driving member 313 may include parameters such as the magnitude of the driving force, the driving direction, and the operating state.

[0096] In some embodiments, the electronic device can adjust the operating parameters of the first driving member 313 according to the relationship between the direction of the second driving force and the rotation direction of the first body 100 under the action of the first driving force. For example, when the direction of the second driving force is the same as the rotation direction of the first body 100 under the action of the first driving force, the electronic device increases the first driving force provided by the first driving member 313, thereby increasing the rotation speed of the first body 100. When the direction of the second driving force is opposite to the rotation direction of the first body 100 under the action of the first driving force, the electronic device decreases the first driving force provided by the first driving member 313, thereby decreasing the rotation speed of the first body 100; or, the electronic device controls the first driving member 313 to enter a non-operating state, thereby stopping the rotation of the first body 100; or, the electronic device controls the first driving force of the first driving member 313 to change to the opposite direction, thereby causing the first body 100 to rotate in the opposite direction. When the direction of the second driving force is neither the same as nor opposite to the rotation direction of the first body 100 under the action of the first driving force, but satisfies the perpendicular condition, the electronic device controls the first driving member 313 to enter a non-operating state, thereby stopping the rotation of the first body 100.

[0097] In some embodiments, the electronic device can be configured such that, during the rotation of the first body 100 relative to the second body 200 driven by the first driving member 313, the electronic device can also switch the rotation angle between the first body 100 and the second body 200 based on the second driving force. That is, the electronic device can automatically rotate the first body 100 to a target angle relative to the second body 200 according to the force applied by the user to the first body 100. The target angle can be set as needed. For example, the target angle can be the angle at which the first body 100 and the second body 200 are opened to 120 degrees, at which the user can view the display screen 110 from a more comfortable angle. Alternatively, the target angle can be the angle at which the first body 100 and the second body 200 are closed to 0 degrees, at which the electronic device is retracted, i.e., the display screen 110 is in its initial position.

[0098] Of course, in some embodiments, there can be multiple target angles. The electronic device can automatically identify the corresponding target angle based on the force applied by the user to the first body 100. For example, the target angle may include 120 degrees and 0 degrees. During the process of the first driving member 313 driving the first body 100 to rotate and open, the user can apply a force to the first body 100 along the opening direction. In response to this force applied by the user to the first body 100, the electronic device increases the driving force of the first driving member 313, so that the first body 100 can quickly open to 120 degrees. During the process of the first driving member 313 driving the first body 100 to rotate and open, the user can apply a force to the first body 100 along the closing direction. In response to this force applied by the user to the first body 100, the electronic device increases the driving force of the first driving member 313, so that the first body 100 can quickly close to 0 degrees.

[0099] In some embodiments, the electronic device may be configured to perform at least one of the following: when the driving direction of the second driving force is the same as the driving direction of the first driving force, increase or decrease the output torque or driving speed of the first driving member 313; when the driving direction of the second driving force is different from the driving direction of the first driving force, control the first driving member 313 to enter a non-working state or provide a reverse driving force; when the second driving force is detected, control the first driving member 313 to enter a non-working state and switch the rotation angle between the first body 100 and the second body 200 under the action of the second driving force; when the second driving force is greater than the first driving force, switch the rotation angle between the first body 100 and the second body 200 under the action of the second driving force.

[0100] The fact that the driving direction of the second driving force is the same as the driving direction of the first driving force means that the direction in which the user manually rotates the first body 100 is the same as the direction in which the electronic device automatically rotates the first body 100 through the first driving member 313. In this case, the first body 100 can be rotated quickly by increasing or decreasing the output torque or driving speed of the first driving member 313. For example, if the driving direction of the second driving force is the same as the driving direction of the first driving force, and the second driving force is greater than the first driving force, then the output torque or driving speed of the first driving member 313 is decreased so that the first body 100 can complete the rapid rotation mainly under manual action; if the driving direction of the second driving force is the same as the driving direction of the first driving force, and the second driving force is less than the first driving force, then the output torque or driving speed of the first driving member 313 is increased so that the first body 100 can complete the rapid rotation mainly under self-driving action.

[0101] When the driving direction of the second driving force is different from that of the first driving force, the power of the electronic device or the manpower of the user can be saved by controlling the first driving member 313 to enter a non-working state or to provide a reverse driving force. For example, if the driving direction of the second driving force is opposite to that of the first driving force and the second driving force is greater than the first driving force, the first driving member 313 is controlled to enter a non-working state so that the first body 100 can complete the rotation entirely under manual operation. If the driving direction of the second driving force is opposite to that of the first driving force and the second driving force is less than the first driving force, the first driving member 313 is controlled to move in the opposite direction (e.g., the motor reverses) so that the first driving member 313 provides a driving force in the same direction as the second driving force, and the first body 100 completes the rotation by automatically rotating to assist manual rotation or by fully automatically rotating.

[0102] When a second driving force is detected, controlling the first driving member 313 to enter a non-operating state means that once the electronic device detects that the first body 100 is subjected to a force applied by the user, regardless of the magnitude relationship between the force applied by the user and the first driving force provided by the first driving member 313, it controls the first driving member 313 to stop working, allowing the first body 100 to rotate entirely under manual operation. Alternatively, a step can be added to determine the magnitude relationship between the force applied by the user and the first driving force provided by the first driving member 313. If the second driving force is greater than the first driving force, i.e., the force applied by the user is larger, the electronic device switches the rotation angle between the first body 100 and the second body 200 under the action of the second driving force. Furthermore, when the second driving force is greater than the first driving force, the decision to control the first driving member 313 to enter a non-operating state can also be based on the relationship between the driving directions of the second and first driving forces. For example, if the driving directions of the second and first driving forces are opposite, then the first driving member 313 is controlled to stop working.

[0103] In some embodiments, the connecting device 300 may further include a second rotating shaft assembly 320 connected to the first rotating shaft assembly 310. The first rotating shaft assembly 310 may be disposed on the second body 200 to realize relative rotation of the first body 100 and the second body 200 in the torsional direction T. The second rotating shaft assembly 320 may be disposed on the first body 100 to realize relative rotation of the first body 100 and the second body 200 in the opening and closing direction K. That is, when configuring the component providing the rotating axis of torsional rotation and the component providing the rotating axis of opening and closing rotation in the connecting device 300, the component providing the rotating axis of torsional rotation may be disposed on the second body 200, and the component providing the rotating axis of opening and closing rotation may be disposed on the first body 100. Of course, in other embodiments, the positions of the two components providing different rotating axes may be interchanged; that is, the component providing the rotating axis of torsional rotation may be disposed on the first body 100, and the component providing the rotating axis of opening and closing rotation may be disposed on the second body 200.

[0104] In some embodiments, the first rotating shaft 311 may include a first shaft body 311a and a second shaft body 311b that are vertically connected. The first shaft body 311a may be disposed on the second body 200, and the second shaft body 311b may be disposed on the first edge 120 of the first body 100. That is, the first shaft body 311a is rotatably connected to the second body 200, and the first axis S1 of the first shaft body 311a may be the rotation axis of the first body 100 and the second body 200 rotating relative to each other in the torsional direction T. The second shaft body 311b is located at the first edge 120 of the first body 100 and is rotatably connected to the first body 100, and the second axis of the second shaft body 311b may be the rotation axis of the first body 100 and the second body 200 rotating relative to each other in the opening and closing direction K. The second rotating shaft assembly 320 may include a first drive module 321 and a second drive module 322 rotatably connected to the second shaft 311b. The first drive module 321 and the second drive module 322 drive the first body 100 to rotate relative to the second body 200 in the opening and closing direction K by providing torque along the circumferential direction of the second shaft 311b. That is, the power source for the first body 100 to automatically rotate relative to the second body 200 in the opening and closing direction may come from the first drive module 321 and the second drive module 322 provided on the first body 100.

[0105] In some embodiments, the first edge 120 of the first body 100 may be inclined from the location of the second shaft 311b toward the opposite ends of the first edge 120, that is, the outline of the first edge 120 of the first body 100 is not parallel to the axis of the second shaft 311b, and the positions of the opposite ends of the first edge 120 are offset toward the same side of the axis of the second shaft 311b compared to the location of the second shaft 311b. Thus, when the first body 100 is rotated to be perpendicular to the second body 200, the first gap J1 between the corner of the first edge 120 of the first body 100 and the second body 200 is greater than the second gap J2 between the location of the second shaft 311b and the second body 200. The corner of the first edge 120 refers to the corner position formed by the edge of the first body 100 adjacent to the first edge 120 and the first edge 120, that is, the corner of the first edge 120 refers to the end position of the first edge 120. That is, when the first body 100 is opened to a 90-degree or approximately 90-degree angle with the second body 200, the gap between the corners at opposite ends of the first edge 120 and the second body 200 is the first gap J1, and the gap between the location of the second shaft 311b and the second body 200 is the second gap J2. The first gap J1 is larger than the second gap J2. With this configuration, during the rotation of the first body 100 relative to the second body 200 in the torsional direction T, the first edge 120 of the first body 100 is less likely to rub against the surface M of the second body 200, thereby helping to reduce collision damage.

[0106] In some embodiments, the contour line of the first edge 120 from the location of the second shaft 311b to the end of the first edge 120 can be set as a straight line or a curve, as long as all positions of this contour line are located on the same side of the axis of the second shaft 311b, and the distance between each position and the axis of the second shaft 311b gradually increases in the direction from the location of the second shaft 311b to the end of the first edge 120. That is, the closer the position is to the corner of the first edge 120, the greater the distance from the axis of the second shaft 311b. In order to configure the mass distribution of the electronic device more evenly, the location of the second shaft 311b can be the middle position of the first edge 120, and the contour line of the first edge 120 extends symmetrically to both ends from the location of the second shaft 311b.

[0107] In some embodiments, a flexible element 140 may be provided at the corner of the first edge 120. The material of the flexible element 140 may be, for example, rubber, silicone, etc. Since the flexible element 140 is made of a soft material, in the event that the corner of the first edge 120 of the first body 100 accidentally comes into contact with the surface M of the second body 200 (this situation usually does not occur, or the probability of it occurring is extremely low), the flexible element 140 can contact the surface M of the second body 200 to avoid scratches on the surface M of the second body 200.

[0108] In some embodiments, the first drive module 321 and the second drive module 322 may be disposed at opposite ends of the second shaft 311b, i.e., distributed along the axial direction of the second shaft 311b. The first drive module 321 and the second drive module 322 may be rotatably connected to the second shaft 311b via the second rotating shaft 323, and drive the first body 100 to rotate relative to the second body 200 in the opening / closing direction K by providing circumferential torque along the second shaft 311b. For example, the second rotating shaft 323 may pass through the second shaft 311b, with the first drive module 321 and the second drive module 322 connected at both ends respectively. In this way, the first drive module 321 and the second drive module 322 may synchronously drive the first body 100 to rotate relative to the second body 200 in the opening / closing direction K via the same component (i.e., the second rotating shaft 323), making the driving force more balanced and the opening / closing movement smoother.

[0109] In some embodiments, the axis of the second rotating shaft 323 and the axis of the second shaft body 311b may not coincide, that is, the second rotating shaft 323 and the second shaft body 311b may be arranged non-coaxially. This facilitates the installation of a damping element inside the second shaft body 311b. The damping element can be used to realize the hovering function of the first body 100. That is, during the rotation of the first body 100 relative to the second body 200 in the opening and closing direction K, after all driving forces are stopped, it can stop at the current rotation position by relying on the damping force of the damping element.

[0110] In some embodiments, the positional relationship between the first shaft 311a and the second body 200 can be configured such that the angle between the axis of the first shaft 311a and the surface M of the second body 200 is greater than 90 degrees. See also Figure 16The axis of the first shaft 311a (i.e., the first axis S1) is not perpendicular to the surface M of the second body 200, but forms an angle greater than 90 degrees with the surface M of the second body 200. That is, the connecting device 300 is located near the target edge of the surface M of the second body 200, and the first axis S1 is inclined towards the target edge relative to the normal of the surface M of the second body 200. Taking a laptop computer as an example, the first axis S1 is inclined away from the keyboard assembly relative to the main body of the laptop. This effectively reduces the possibility of the first edge 120 contacting the surface M of the second body 200 during the twisting process of the first body 100 relative to the second body 200, thus improving the safety of the first body 100 during the twisting process. Because the angle between the first axis S1 of the first shaft 311a and the surface M of the second body 200 is greater than 90 degrees, the plane of motion for the torsion of the first body 100 relative to the second body 200 is not parallel to the surface M of the second body 200, but rather inclined. This causes the distance between the corner of the first edge 120 and the surface M of the second body 200 to change as the first body 100 twists. (See also...) Figure 1 , Figure 4 and Figure 5 , the first ontology 100 since Figure 1 The state shown is rotated 90 degrees to switch to Figure 4 After the state shown, the corner of the first edge 120 located above the surface M of the second body 200 and the second body 200 form a third gap J3, which is larger than the first gap J1.

[0111] In some embodiments, the first rotating shaft assembly 310 may further include a rotating shaft housing 312 disposed within a first receiving space of the second body 200. The rotating shaft housing 312 confines the first rotating shaft 311, the first driving member 313, and the transmission mechanism within a second receiving space formed by itself or in cooperation with the housing of the second body 200. The housing of the second body 200 can provide the first receiving space, and the rotating shaft housing 312 can be fixedly installed within the first receiving space of the second body 200. The rotating shaft housing 312 can be used to form the second receiving space, and the first rotating shaft 311, the first driving member 313, and the transmission mechanism can be arranged within the second receiving space. The second accommodating space can be formed solely by the pivot housing 312, or it can be formed jointly by the pivot housing 312 and a portion of the housing of the second body 200. For example, the pivot housing 312 may include a first pivot housing 312a and a second pivot housing 312b spaced apart from the first pivot housing 312a, with the first pivot housing 312a and the second pivot housing 312b forming the second accommodating space. Alternatively, the pivot housing 312 may only have one of the first pivot housing 312a and the second pivot housing 312b, without the other, with the first pivot housing 312a or the second pivot housing 312b forming the second accommodating space with the housing of the second body 200.

[0112] The first rotating shaft assembly 310 may further include an adjusting member 510 for adjusting the spatial height of the second receiving space and an elastic member 520 for configuring the elastic pressure between the first rotating shaft 311 and the rotating shaft housing 312 and the first transmission member 317, wherein the adjusting member 510 is capable of adjusting the magnitude of the elastic pressure. That is, by operating the adjusting member 510, the spatial height of the second receiving space can be changed, thereby changing the amount of elastic deformation of the elastic member 520, and thus changing the magnitude of the elastic pressure between the first rotating shaft 311 and the rotating shaft housing 312 and the first transmission member 317. The elastic pressure refers to the pressure of the contacting components in the direction of elastic deformation of the elastic member 520, which can affect the frictional force between the contacting components. Therefore, by operating the adjusting member 510, the frictional force between the first transmission member 317 and the first rotating shaft 311, and between the first transmission member 317 and the rotating shaft housing 312, can be adjusted.

[0113] See Figures 9-12In some embodiments, the pivot housing 312 may include a first pivot housing 312a fixed to the second body 200 and a second pivot housing 312b spaced apart from the first pivot housing 312a. The adjusting member 510 can adjust the distance between the first pivot housing 312a and the second pivot housing 312b. The first pivot 311 may include a first shaft 311a passing through the first pivot housing 312a, and the elastic member 520 may be sleeved on the portion of the first shaft 311a located between the first pivot housing 312a and the second pivot housing 312b. The first shaft 311a is rotatably mounted on the first shaft housing 312a via a bearing 400. The elastic element 520 can be, for example, a disc spring or a coil spring. The elastic element 520 is sleeved on the first shaft 311a and abuts against the inner ring of the bearing 400 and a portion of the first shaft 311a. As the distance between the first shaft housing 312a and the second shaft housing 312b decreases, the axial pressure along the first shaft 311a increases between the first shaft 311a and the first transmission member 317, and between the first transmission member 317 and the second shaft housing 312b. Correspondingly, the frictional force between the first shaft 311a and the first transmission member 317, and between the first transmission member 317 and the second shaft housing 312b, increases. Conversely, as the distance between the first shaft housing 312a and the second shaft housing 312b increases, the pressure and the corresponding frictional force decrease.

[0114] In some embodiments, the adjusting member 510 can be configured as a bolt, which can be operated by a screwing action for convenience and speed. Of course, the adjusting member 510 can also be configured in other forms. For example, the adjusting member 510 can be configured as a shim arranged between the second rotating shaft housing 312b and the housing of the second body 200. By increasing or decreasing the number of shims, the distance between the second rotating shaft housing 312b and the housing of the second body 200 can be changed, thereby indirectly adjusting the spacing between the first rotating shaft housing 312a and the second rotating shaft housing 312b.

[0115] In some embodiments, a first friction element 710 may be provided between the first transmission member 317 and the first rotating shaft 311, and a second friction element 720 may be provided between the first transmission member 317 and the second rotating shaft housing 312b. The first friction element 710 is fixed to the first transmission member 317 and is used to configure the frictional force between the first transmission member 317 and the first rotating shaft 311. The second friction element 720 may be fixed to the second rotating shaft housing 312b, indirectly realizing the configuration of the frictional force between the first transmission member 317 and the second body 200. Figure 11As shown, the first friction element 710 can be configured to only make contact with the first shaft 311a in the axial direction of the first shaft 311a, but not in the radial direction of the first shaft 311a. This can reduce the resistance when adjusting the distance between the first shaft housing 312a and the second shaft housing 312b.

[0116] The first shaft 311a may be provided with an annular protrusion, which presses against the first friction member 710 to form axial contact along the first shaft 311a. The coefficient of friction between the first friction member 710 and the first shaft 311a may be the same as or different from the coefficient of friction between the second friction member 720 and the first transmission member 317. When the coefficient of friction is the same, the magnitude of the torque generated by the frictional force on the first shaft 311a at the two locations may be different due to the different sizes of the contact areas or the different distances from the center of the contact area to the axis of the first shaft 311a (i.e., the first axis S1).

[0117] Of course, in other embodiments, friction elements may not be provided, and friction may be generated by the first transmission element 317 directly contacting other components. For example, the first friction element 710 may not be provided, and the first transmission element 317 may directly contact the annular protrusion of the first shaft 311a. As another example, the second friction element 720 may not be provided, and the first transmission element 317 may directly contact the second rotating shaft housing 312b.

[0118] In some embodiments, the transmission mechanism may further include a worm 314, a worm wheel 315, and a gear set 316 disposed between the output end of the first drive member 313 and the first transmission member 317. The first transmission member 317 may be configured as a gear, meshing with the final gear of the gear set 316. Of course, in other embodiments, the transmission mechanism may be configured in other forms, such as a belt drive mechanism, which is not limited in this application.

[0119] In some embodiments, the first rotating shaft assembly 310 may further include a rotating disk 610 drivenly connected to the first shaft 311a and a magnetic encoder 630 for determining the rotation angle of the first shaft 311a by detecting the rotation data of the rotating disk 610. The electronic device can control the output torque and / or direction of the first drive member 313 based on the rotation angle of the first shaft 311a determined by the magnetic encoder 630 to switch to different device configurations. The rotating disk 610 may be drivenly connected to the first shaft 311a, and there is a defined transmission ratio between them. Therefore, the rotation angle of the rotating disk 610 indirectly reflects the rotation angle of the first shaft 311a, and the rotation angle of the first shaft 311a can reflect the rotation angle of the first body 100 relative to the second body 200. The magnetic encoder 630 can detect the rotation data of the rotating disk 610 through magnetic induction. For example, the magnetic encoder 630 may be fixed to the first rotating shaft housing 312a or the second rotating shaft housing 312b, and the magnetic element 620 may be fixed to the rotating disk 610 and magnetically engaged with the magnetic encoder 630. The magnetic encoder 630 can obtain the position information of the magnetic component 620 through magnetic induction, reflecting the rotation data of the rotating disk 610. The rotation data can include rotation angle, rotation speed, rotation direction, etc.

[0120] In some embodiments, the electronic device can control the output torque and / or steering of the first drive member 313 based on the rotation angle of the first shaft 311a determined by the magnetic encoder 630. For example, the first drive member 313 can drive the first body 100 to rotate relative to the second body 200 within a certain range. The electronic device can obtain the rotation angle of the first body 100 relative to the second body 200 through the magnetic encoder 630, and thus determine its current position within the rotatable range. If the current position is far from the limit position of the rotatable range, the first drive member 313 can be controlled to drive the first body 100 with a larger output torque or driving speed. If the current position is close to the limit position of the rotatable range, the first drive member 313 can be controlled to drive the first body 100 with a smaller output torque or driving speed, thereby causing the first body 100 to rotate slowly to the limit position, improving safety. If the device is already at the limit of its rotatable range, the first drive unit 313 can be controlled to stop working or rotate in the opposite direction. This prevents the first shaft 311a from generating unwanted resistive torque with the second body 200 due to excessive rotation, which could cause excessive load and damage to the first shaft 311a and other related load-bearing components. The electronic device, based on the rotation angle of the first shaft 311a determined by the magnetic encoder 630, can determine the relationship between the current device configuration and the next device configuration to be switched to. Therefore, it can determine whether to adjust the direction of the first drive unit 313 according to the needs of switching device configurations.

[0121] In some embodiments, the electronic device may be configured such that when the magnetic encoder 630 senses that the magnetic element 620 has reached a preset limit position, the first drive member 313 enters a non-operating state. The preset limit position is the position of the magnetic element 620 when the first body 100 rotates relative to the second body 200 to the end of its rotatable range. For example, the first body 100 may be configured to be able to rotate relative to the second body 200. Figure 1 The state shown rotates within the range of -90 degrees to +90 degrees along the torsional direction T. If the magnetic component 620 reaches the preset limit position, it reflects that the first body 100 has reached a relative position. Figure 1 When the state shown is at a position of -90 degrees or +90 degrees along the torsion direction T, the electronic device controls the first drive unit 313 to enter a non-working state, which can prevent the first body 100 from being excessively twisted, thereby improving safety.

[0122] In some embodiments, the electronic device may include a light-emitting component, which may be located within a third receiving space formed by the cooperation of the display screen 110 and the housing of the first body 100. Light emitted by the light-emitting component passes through the gap between the light-emitting component and the second shaft 311b and illuminates both sides of the axis of the second shaft 311b. See also Figure 1 , Figure 4 and Figure 13 Because the light emitted by the light-emitting component passes through the gap between the light-emitting component and the second axis 311b and illuminates both sides of the axis of the second axis 311b, the user can easily observe the light emitted by the light-emitting component regardless of the position of the first body 100 relative to the second body 200, facilitating light-based interaction between the electronic device and the user. For example, the electronic device can be equipped with an artificial intelligence unit, allowing the user to interact with the AI ​​agent of the electronic device via voice. The light emitted by the light-emitting component can be used to indicate to the user whether the AI ​​agent of the electronic device is awake. As the user moves around the electronic device, they can easily see the light emitted by the light-emitting component regardless of their location around the device, further enhancing the convenience of light-based interaction between the user and the electronic device.

[0123] The light-emitting component may include a light-emitting element 810, a light chamber 820, and a light guide 830. The light guide 830 is located on the side of the light-emitting component closer to the second shaft 311b, forming a gap between the light guide 830 and the second shaft 311b. Light emitted from the light-emitting element 810 is reflected within the light chamber 820 and then guided by the light guide 830 to both sides of the axis of the second shaft 311b. By providing the light chamber 820 and the light guide 830, relatively high brightness light can be generated while reducing the size of the light-emitting component. The light-emitting component may include a power supply line 850 and a relay 840. The power supply line 850 is connected to the relay 840, and the relay 840 is connected to the light-emitting element 810.

[0124] See Figure 2 and Figure 5 In some embodiments, an audio output component located at the corner of the first edge 120 may be disposed inside the first body 100, and the housing of the first body 100 may be provided with a mesh 130 corresponding to the audio output component, through which sound emitted by the audio output component can be transmitted. Of course, the arrangement range of the mesh 130 may extend beyond the range corresponding to the audio output component; the mesh 130 located in the extended area can be used for heat dissipation, meaning that heat inside the first body 100 can be dissipated through the mesh 130. In some embodiments, audio output components may be disposed at the corners of opposite ends of the first edge 120, which is beneficial for achieving stereo sound and improving the user's auditory experience.

[0125] In some embodiments, the electronic device may further include at least one controller disposed in the first body 100 and / or the second body 200. After receiving a target control command, the controller can determine the operating parameters of a target driver of the electronic device based on the current device configuration of the electronic device and the target device configuration pointed to by the target control command, and control the target driver to drive the electronic device to switch from the current device configuration to the target device configuration with the operating parameters. The target driver is at least one of a plurality of drivers in the first pivot assembly 310 and the second pivot assembly 320 of the electronic device. The operating parameters of the target driver in the current device configuration or the target device configuration are different from the operating parameters in the first device configuration. The first device configuration is an intermediate device configuration between the current device configuration and the target device configuration.

[0126] According to embodiments of this application, the target control command may include an open cover command, a close cover command, a switch to tablet mode command, a switch from tablet mode to a closed cover state command, a switch from a 180-degree open / closed state command to tablet mode command, etc. The open cover command is a command that gradually increases the angle between the first body 100 and the second body 200. The close cover command is a command that gradually decreases the angle between the first body 100 and the second body 200. The switch to tablet mode command instructs the electronic device to switch from its current device form to a device form where the angle between the first body 100 and the second body 200 is approximately 180 degrees.

[0127] According to embodiments of this application, the triggering operations for different control commands can be different, such as triggering the corresponding control command through the power button, manually opening and closing the screen, voice command input, touch command input, keyboard input, gesture image input, etc.

[0128] According to embodiments of this application, the current device form can be a closed state where the first body 100 and the second body 200 abut against each other, a 180-degree book form (i.e., an unfolded state where the angle between the first body 100 and the second body 200 is close to 180 degrees), a laptop form where the angle between the first body 100 and the second body 200 is in the range of 20 degrees to 165 degrees, a tablet form, etc. According to embodiments of this application, the target device form is the device form that the user wants to switch to. For example, the target device form can be any of the following forms: a closed state, a 180-degree book form, a laptop form where the angle between the first body 100 and the second body 200 is in the range of 20 degrees to 165 degrees, a tablet form, etc.

[0129] The target drive unit may include at least one of multiple drive units. For example, the target drive unit may be a first drive unit 313 and / or a first drive module 321 and / or a second drive module 322. The target drive unit may be one motor, two motors, or three motors. As an example, operating parameters may include combinations of at least one or more of voltage, current, speed, torque, and power. As an example, operating parameters may also include the rotation direction of the output shaft of the target drive unit. For example, the output shaft may rotate clockwise or counterclockwise.

[0130] Switching from the current device form to the target device form can include switching from a closed state to a laptop form, a tablet form, a shared form (the display screen 110 faces away from the user), a book form, or a dancing form (i.e., the first body 100 and the second body 200 maintain a target angle that is neither 0 degrees nor 180 degrees, and the connecting device 300 is in a follow-up or active adjustment state), etc.

[0131] As an example, the operating parameters include at least the output torque of the target drive component, which can be controlled by adjusting the voltage applied to the target drive component. Based on the different driving force requirements of the electronic device at different stages of movement, the operating parameters of the target drive component in the current device configuration or the target device configuration differ from those in the first device configuration, specifically manifested as differentiated configurations of the output torque. Specifically, in the initial stage of the opening process (i.e., switching from a folded state to an unfolded state), the target drive component needs to provide a larger starting torque to overcome the maximum static friction or holding force generated by structural characteristics or external forces (such as the adsorption components disposed on the first body 100 and the second body 200) when the device is in the closed state; while during the rotation process after the opening action is initiated, the required holding torque is usually less than the torque in the initial stage. Correspondingly, in the closing process (i.e., switching from an unfolded state to a folded state), the output torque of the target drive component is also dynamically adjusted according to the configuration change.

[0132] As an example, once the electronic device is closed to a specific angle (e.g., 45 degrees), the target drive is controlled to reduce the output torque. This is because during the subsequent stroke, the attraction force (e.g., magnetic attraction) between the adsorption components (described in detail later) increases rapidly, creating a strong tendency for automatic closing. Reducing the drive torque at this point allows the adsorption force to assist in closing the device, preventing it from closing too abruptly and causing impact.

[0133] As an example, when the electronic device is closed to a specific small angle range (e.g., 7.5 degrees to 0 degrees) near a closed state, the target drive is controlled to increase the output torque until the motor's stall torque is reached. The mechanical self-locking force generated by the motor stall ensures that the first body 100 and the second body 200 are tightly fitted to 0 degrees and remain locked, eliminating the gap between the first body 100 and the second body 200.

[0134] By dynamically adjusting the output torque according to the device's shape (such as 0 degrees, 7.5 degrees, 45 degrees, etc.), the electronic device can match the mechanical characteristics of different stages (such as the initial start-up stage, intermediate rotation stage, and final locking / engaging stage), achieving smooth and reliable shape switching while reducing energy consumption.

[0135] According to embodiments of this application, a first device form refers to any intermediate form, excluding the starting and ending points, that an electronic device passes through during the process of switching from its current device form to a target device form. Specifically, the first device form can be characterized by the rotation angle of the device's pivot. For example, during the opening process of switching from a folded state (0 degrees) to an unfolded state (180 degrees), when the angle between the first body 100 and the second body 200 reaches a preset 7.5 degrees, this state can be defined as the first device form; similarly, during the closing process of switching from an unfolded state (180 degrees) to a folded state (0 degrees), when the angle between the two reaches 45 degrees, this state can also be considered the first device form.

[0136] Since the mechanical requirements of the target drive component in the first device configuration are different from those in the current device configuration or the target device configuration, the controller will configure specific operating parameters for the first device configuration (such as adjusting torque output) to adapt to the resistance characteristics at different angles (such as overcoming starting resistance, using magnetic attraction, or achieving stall locking).

[0137] According to embodiments of this application, the target driving member drives the first body 100 and the second body 200 to move relative to each other in at least one direction, including but not limited to the following types of movement or combinations thereof:

[0138] The opening and closing motion is that the first body 100 rotates relative to the second body 200 around a second axis parallel to the surface M of the second body 200, changing the angle between the first body 100 and the second body 200.

[0139] Torsional motion, that is, the first body 100 rotates relative to the second body 200 around the first axis S1 perpendicular to the second axis, changing the included angle between the first edge 120 of the first body 100 and the side of the surface M of the second body 200 near the connecting device 300.

[0140] The composite motion refers to the simultaneous rotation of the first body 100 and the second body 200 relative to each other around the first axis S1, and rotation around the second axis. This composite motion enables more complex transformations of the device configuration.

[0141] By controlling the movement of the target drive component in any one or more of the above-mentioned directions of motion, the electronic device can flexibly switch between various forms such as unfolded state, folded state, and hovering state.

[0142] The controller is electrically connected to the drive components (first drive component 313, first drive module 321, and second drive module 322) in the first rotating shaft assembly 310 and the second rotating shaft assembly 320. If only the screen opening angle needs to be adjusted, the controller will only identify the two drive modules of the second rotating shaft assembly 320 as the target drive components. If the opening angle and the torsion angle need to be adjusted at the same time (i.e., to perform compound motion), the controller will identify the two drive modules of the second rotating shaft assembly 320 and the first drive component 313 of the first rotating shaft assembly 310 as the target drive components, and send the corresponding working parameters (such as voltage or torque commands) to the three target drive components respectively to achieve motion decoupling and synchronous control.

[0143] In some embodiments, the electronic device may further include an input device disposed on the second body 200, which may include at least one of a keyboard, a touchpad, and a touch display screen. As an example, the input device may be disposed on the surface M of the second body 200.

[0144] In some embodiments, the electronic device may further include at least one detection element for detecting the angle between the first body 100 and the second body 200, and the detection element may also provide feedback to the controller on the angle between the first body 100 and the second body 200 when the device mode switching is completed. As an example, the detection element may include a magnetic encoder and a rotating disk 610 disposed on the first rotating shaft assembly 310, and the detection element may include a potentiometer disposed on the second rotating shaft assembly 320.

[0145] According to embodiments of this application, controlling the target driver to drive the electronic device to switch from a current device mode to a target device mode with operating parameters may include at least one of the following:

[0146] In response to receiving a power-on command, the second rotating shaft assembly 320 of the electronic device drives the first body 100 to rotate along the opening and closing direction K with a first output torque, and after rotating at a first angle, rotates to a second angle corresponding to the target device shape with a third output torque, wherein the first output torque is greater than the third output torque.

[0147] In response to receiving a power-off command, the second rotating shaft assembly 320 of the control electronic device drives the first body 100 to rotate toward the second body 200 with a fourth output torque, and when it is detected that the included angle between the first body 100 and the second body 200 is less than a third angle, the first drive module 321 and / or the second drive module 322 control the first body 100 to rotate to the closed position with a second output torque, the second output torque being greater than the fourth output torque;

[0148] In response to the target user's closing operation on the first body 100, when the angle between the first body 100 and the second body 200 is detected to be less than a third angle, the second rotating shaft assembly 320 is activated and the first body 100 is driven to rotate to the closed position with a second output torque.

[0149] In this embodiment, the strategy employs a segmented control approach of "strong first, weak later" when responding to the power-on command. The first output torque is designed to be a larger value, specifically to overcome the maximum static friction and potential initial magnetic resistance generated when the device is stationary for extended periods (especially at low temperatures or when grease is condensing), ensuring reliable triggering of each power-on action and preventing motor stalling or startup failure. After rotating the first angle, the output torque immediately switches to a smaller third value. This not only meets the power requirements for continued rotation but also avoids motion overshoot or impact caused by sustained high torque, making the screen unfolding action crisp and clean at the moment of startup, followed by a smooth and stable transition, avoiding the startling sensation or mechanical wear caused by a sudden "pop-up."

[0150] In response to shutdown commands or user lid-closing operations, the strategy introduces a position-based "high-torque intervention mechanism." When the device rotates to a near-closed critical state (angle less than the third angle), the controller automatically increases the drive torque to the second output torque. Because this torque is greater than the fourth output torque during normal operation, it provides a strong "active pull" for the device in the final closing stroke. This feature is particularly crucial for solving the "smiling" problem caused by non-magnetic designs or shaft wear, forcibly overcoming shaft rebound force and mechanical tolerances, ensuring a tight fit between the first body 100 and the second body 200, and enhancing the product's integrated appearance and premium feel.

[0151] For scenarios where the user manually closes the lid, the controller doesn't simply let the motor shut off. Instead, it intelligently starts the motor and provides high torque (second output torque) assistance when it detects that the user has pushed the device to a critical angle (less than the third angle). This means that the user only needs to push gently (e.g., to 30 or 15 degrees), and the device will automatically sense this and complete the remaining closing action with maximum locking force. This "semi-automatic" interaction method reduces the user's operational burden (no need to forcefully tap the lid) while ensuring a standardized locking effect every time the device is closed, avoiding the problem of the first body not being fully closed due to insufficient user force. As an example, the first angle can be 7.5 degrees or 15 degrees, and the second angle can be 90 degrees, 135 degrees, 180 degrees, etc.

[0152] As an example, taking the process of an electronic device switching from a closed state (0 degrees) to an unfolded state as an example, the output torque control strategy of the second pivot assembly 320 (first drive module 321 and second drive module 322) will be explained in detail:

[0153] In the initial stage of device configuration switching, when the angle between the first body 100 and the second body 200 is between 0 and 7.5 degrees, the second rotating shaft assembly 320 is controlled to output a first output torque. This first output torque can be specifically set to 10 kgf.cm (kgf.cm represents the torque generated by one kilogram of force acting on a one-centimeter lever). This high torque value is used to overcome the maximum adsorption force generated by the adsorption components (e.g., magnetic attraction structures) and the maximum static friction force of the first rotating shaft assembly 310 when the device is closed, ensuring reliable startup of the first body 100 and preventing stalling. Once the first body 100 rotates more than 7.5 degrees, it enters a smooth rotation stage, and the control strategy is adjusted accordingly. The controller reduces the output torque of the second rotating shaft assembly 320 from the first output torque to a third output torque. This third output torque can be specifically set to 7 kgf.cm. During the subsequent stroke from 7.5 degrees to the target angle (e.g., 90 or 180 degrees), since the adsorption force of the adsorption component has been released or reduced, the output torque of 7 kgf.cm is sufficient to overcome the gravitational component and dynamic friction of the first body 100 to maintain smooth movement. Reducing the torque output helps to reduce equipment energy consumption, reduce motor operating noise, and improve the smoothness of the form switching process. Through the above-mentioned stepped torque control of 10 kgf.cm followed by 7 kgf.cm, the controller balances the reliability of startup with the energy efficiency of operation.

[0154] According to embodiments of this application, the electronic device employs a dual control strategy based on stall detection and position feedback during the process of electrically shutting down and closing the first body 100, including:

[0155] In response to the power-off command, the controller sends a control signal to the motor drive circuit to control the motor to drive the first body 100 to rotate toward the second body 200 and perform a closing action;

[0156] The motor drives the first body 100 to move until the first body 100 reaches -5 degrees in the logical position.

[0157] It should be understood that -5 degrees is a virtual zero-crossing angle, representing the motor continuing to perform a preset number of tiny rotation steps from the physical closed position (0 degrees). Its purpose is to generate the required locking force through a slight interference deformation of the mechanical structure, thereby eliminating the "smiley" phenomenon.

[0158] During the movement towards the -5 degree position, the motor is effectively unable to continue rotating due to mechanical limiting, resulting in a stall. The controller monitors the motor's current or pulse signals in real time; when the detected current value exceeds the preset stall threshold (i.e., a stall signal is detected), it determines that the mechanical structure has reached the locking state, and the controller immediately controls the motor to stop outputting power. Simultaneously, the controller obtains the actual physical position information of the first body 100 through an angle recognition device (such as a Hall sensor or encoder).

[0159] When the angle sensor detects that the first body 100 is at 0 degrees (physical closed position), the controller confirms that the device is in the correct closed position and updates or locks the position data, ending the entire shutdown process.

[0160] Through the above steps, the equipment achieves automatic locking by utilizing the high torque output of the motor before it stalls. At the same time, the stall detection mechanism prevents the motor from being damaged by prolonged overload, and the angle sensor ensures the accuracy of the shutdown state.

[0161] As an example, the fourth output torque can be 7 kgf.cm. As an example, the third angle can be 7.5 degrees.

[0162] According to an embodiment of this application, during the transition from the current device configuration to the closed configuration, the controller controls the second rotating shaft assembly 320 to drive the first body 100 to rotate toward the second body 200 with a second output torque. When it is detected that the angle between the first body 100 and the second body 200 is less than a preset angle (such as a third angle), the controller controls the second rotating shaft assembly 320 to output the second output torque. This second output torque is set to a large torque value sufficient to overcome the shaft rebound force and mechanical damping, driving the first body 100 to continue moving toward the closed position.

[0163] After the first body 100 reaches its physical limit position (e.g., 0 degrees), the motor of the second shaft assembly 320 will enter a stall state due to mechanical limiting. Unlike conventional instantaneous shutdown protection, after detecting a stall signal (e.g., current exceeding a threshold), the controller controls the second shaft assembly 320 to continue outputting the second output torque in the stall state for a certain duration (e.g., 0.1 to 2 seconds). This stall maintenance process uses continuous motor torque to apply "interference pressure" to the shaft system, forcibly eliminating potential gaps caused by component tolerances or elastic deformation, ensuring that the first body 100 and the second body 200 are tightly locked together.

[0164] During or at the end of the stall maintenance period, the system synchronously detects the position feedback of the first body 100 in real time through an angle sensor or encoder. When the angle feedback information confirms that the first body 100 is at the preset angle (such as 0 degrees) corresponding to the closed position, the controller issues a shutdown command to cut off the power supply to the second rotating shaft assembly 320 and end the position switching process.

[0165] According to an embodiment of this application, in response to a user's manual closing operation on the first body 100, the angle recognizer of the electronic device monitors the relative angle between the first body 100 and the second body 200 in real time. When the angle is detected to decrease to a preset trigger angle (e.g., 7.5 degrees), it is determined that the user has completed the initial closing action, and the system triggers an automatic electric locking program. In response to the trigger angle, the controller sends a control command to the second rotating shaft assembly 320 (motor), controlling the second rotating shaft assembly 320 to start. The motor takes over the closing action with a second output torque (high torque), driving the first body 100 to continue rotating from 7.5 degrees towards the target position. The motor drives the first body 100 past the physical closed position (0 degrees) and continues rotating to the logical position -5 degrees. Through this virtual -5 degree stroke, the motor applies a continuous interference driving force to the rotating shaft system.

[0166] During the process of the first body 100 reaching the -5 degree logical position, the motor enters a stall state due to mechanical limiting. The controller monitors the motor's operating status in real time. When a stall signal is detected (such as the current reaching the stall threshold), the controller controls the motor to maintain output in the stall state for a certain duration (e.g., 0.5 seconds) to ensure that the mechanical structure is fully fitted under pressure, eliminating the risk of a gaping hole. During or after the stall maintenance phase, the controller obtains position feedback information from the angle recognizer. When it is confirmed that the first body 100 is at 0 degrees (the physical closed position), the controller determines that the closing action has been completed and then controls the second rotating shaft assembly 320 to stop moving, ending the entire closing process.

[0167] Through the above process, the user only needs to push the first body 100 to 7.5 degrees and then let go. The subsequent automatic suction, strong pressing and gap elimination actions are all completed automatically by the equipment, which greatly improves the user's convenience and the high-end feel of the equipment.

[0168] In some embodiments, the electronic device may further include an adsorption component disposed on the second edge of the first body 100 and the second body 200. After receiving a power-on command, the controller controls the second rotating shaft assembly 320 of the electronic device to drive the first body 100 to rotate along the opening / closing direction K with a first output torque, and after rotating by a first angle, rotates to a second angle corresponding to the target device shape with a third output torque. The first output torque is greater than the third output torque. The second edge is the edge of the first body 100 and the second body 200 that is respectively away from the connecting device 300. Taking the first body 100 as an example, the second edge of the first body 100 is the edge that is away from the first edge 120. As an example, the adsorption component may be a magnetic component, which may include two magnets or a combination of magnets and a ferromagnetic material (such as iron or an iron-containing alloy).

[0169] In such an embodiment, the second pivot assembly 320 is configured to overcome the adsorption force of the adsorption assembly and the component force of the first body 100 along the gravity direction during the process of the drive module (first drive module 321 and second drive module 322) driving the first body 100 to open in the opening and closing direction K, so that the surfaces M of the display screen 110 and the second body 200 are separated.
