DETAILED DESCRIPTION OF THE EXECUTION FORMS

[0006] Various schemes and features of the present disclosure are described below with reference to the accompanying drawings. The terms used in the present disclosure serve only to explain the specific embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. It is understandable to those skilled in the art that, with technical progress and the emergence of new scenarios, the technical solutions provided in the embodiments of the present disclosure may also be applicable to similar technical problems.

[0007] The terms “first”, “second”, and “third” appearing in this disclosure serve only to distinguish similar objects and do not represent a specific order of the objects. It is understood that, where permitted, the objects described by “first”, “second”, or “third” may be in a different order or sequence, so that the embodiments of this disclosure described herein may be implemented in a different order than that illustrated or described herein.The terms "comprise" and "have" and all variations thereof are intended to cover a non-exclusive scope, so that a process, method, system, product, or device having a number of elements is not necessarily limited to those elements but may also have other elements not expressly listed or inherent in such process, method, product, or device. Unless otherwise defined, all technical and scientific terms used in this disclosure have the meanings commonly understood by those skilled in the art. The terms used in this disclosure serve only descriptive purposes and are not intended to limit the scope of this disclosure.

[0008] An electronic device typically comprises a first body, a second body, and a rotating shaft mechanism connecting the first and second bodies. The rotating shaft mechanism is connected to both bodies to allow the first body to open and close at an adjustable angle relative to the second body. This adjustable angle enables the electronic device to remain independent and stationary when in contact with a support object, while also providing convenience for the user.

[0009] In some examples, the second body touches the support object, allowing the second body to act as a support for the first body. The first body can be capable of receiving operations from an operator, such as a control panel or display interface. When using the electronic device, the user can place it on a desk or other support object, with the second body facing the desk or other support object. The electronic device also features a flexible display screen, which can be attached to the first body and / or the second body. The flexible screen is flexible and can undergo adaptive deformation in response to displacement while maintaining its functionality.

[0010] With the increasing multifunctionality of electronic devices, user requirements have also risen. Existing electronic devices have relatively simple display modes that do not meet user needs.

[0011] The present disclosure provides an electronic device to alleviate at least some of the above problems.

[0012] As in Fig. 1, Fig. 2, Fig. 3 and Fig. As shown in Figure 4, in one embodiment the electronic device can comprise a first body 1, a second body 2, and a target assembly. The first body 1 and the second body 2 can form two parts of the electronic device that can be opened and closed. The first body 1 and the second body 2 can be connected by a rotary shaft mechanism. The rotary shaft mechanism can cause the first body 1 to rotate toward or away from the second body 2, thereby opening or closing the electronic device. Taking a laptop as an example, the first body can be a screen component and the second body a main computer component.

[0013] The first body 1 can include a display assembly, which can be a display device used by the electronic device. The display assembly can, for example, be a display screen.

[0014] The first body 1 can have a first display state and a second display state, between which it can switch. The first body 1 can have at least two display states, namely a first display state and a second display state, between which the first body 1 can switch. Optionally, the first body 1 can also have a third display state, which can be a state between the first and second display states. Optionally, the first body 1 can have different structural relationships in the first and second display states. With the change in the relationship between structural components of the first body 1, the center of gravity of the first body 1 can also change. Optionally, the display area (i.e., the size of the area for display) of the first body 1, which serves as the display surface, can be different in the first and second display states.

[0015] The display area of ​​the display assembly in the first display state can differ from the display area of ​​the display assembly in the second display state. The display assembly can have different display areas in the first and second display states. For example, the display output area of ​​the display screen can be different in the first and second display states, allowing users to adjust the display state of the electronic device according to their needs, thereby improving the user experience.

[0016] The target assembly can be located on the rotary shaft mechanism or have a mating relationship with the rotary shaft mechanism.

[0017] Optionally, the target assembly can be in a first target state if it has a first mating relationship with the rotating shaft mechanism, and in a second target state if it has a second mating relationship with the rotating shaft mechanism. Alternatively, the target assembly can have a mating relationship with the first body 1. The target assembly can be in the first target state if it has the first mating relationship with the first body 1, and in the second target state if it has the second mating relationship with the first body 1.

[0018] The second body 2 can be rotatably connected to the first body 1. The target assembly can be used to limit the rotation angle range of the first body 1 relative to the second body 2. The target assembly can have a first target state and a second target state. The target assembly can switch between these states. The main function of the target assembly can be to limit or control the rotation angle range of the first body 1 of the electronic device relative to the second body 2, allowing users to adjust the angle of the first body 1 of the electronic device according to their needs. This allows users to find the appropriate angle for the first body 1 of the electronic device in different display states, thereby improving the user experience of the electronic device.

[0019] In the first target state, the rotation angle range of the first body 1 relative to the second body 2 can be a first angular range, encompassing all angles between 0° and the maximum rotation angle of the first body 1 relative to the second body 2 in the first target state. In the second target state, the rotation angle range of the first body 1 relative to the second body 2 can be a second angular range, encompassing all angles between 0° and the maximum rotation angle of the first body 1 relative to the second body 2 in the second target state. The second angular range can differ from the first angular range. The target assembly can limit or control the upper limit of the rotation angle of the first body 1 relative to the second body 2, thus enabling the electronic device to be stably positioned in various orientations on a desk or other support object.For example, in the first target state, the upper limit of the first angle range can be 135°, and in the second target state, the upper limit of the second angle range can be 120°. That is, in the first target state, the upper limit of the rotation angle of the first body 1 relative to the second body 2 can be 135°, and in the second target state, the upper limit of the rotation angle of the first body 1 relative to the second body 2 can be 120°.

[0020] When the first body 1 switches between the first and second display states, the relationship between the structures of the first body 1 can change, and the display area of ​​the first body can differ. The target assembly can be used to limit the rotation angle range of the first body 1 relative to the second body 2. When the display assembly switches to the first display state, the target assembly can switch to the first target state. In the first target state, the rotation angle range of the first body 1 relative to the second body 2 can be the first angle range. When the display assembly switches to the second display state, the target assembly can switch to the second target state. In the second target state, the rotation angle range of the first body 1 relative to the second body 2 can be the second angle range.This allows the electronic device to have different rotation angle ranges of the first body 1 relative to the second body 2 for different display areas. In this embodiment, the target assembly can be used to limit the rotation angle range of the first body 1 relative to the second body 2, allowing the user to automatically adjust the rotatable angle according to the requirements of different display states. In this embodiment, different display modes can be created by using different display areas of the first body 1, corresponding to different rotatable angles of the first body 1 relative to the second body 2.The user can adjust the rotation angle range of the first body 1 relative to the second body 2 according to the different display areas of the first body 1, thus enabling the electronic device to offer a variety of display modes. Within these different display modes, the user can limit the rotation of the first body 1 relative to the second body 2 within varying rotation angle ranges. The user can adjust the desired rotation angle range for a specific display mode, allowing different users to achieve personalized, adjustable viewing angles that suit the display mode. This improves user comfort, enhances usability, and meets the needs of diverse users.

[0021] Optionally, when the display assembly switches to the first display state (for example, a display area of ​​50 cm × 70 cm), the target assembly can automatically switch to the corresponding first target state and adjust to the first display state with the first angle range (for example, 0 to 130°). When the display assembly switches to the second display state (for example, a display area of ​​50 cm × 80 cm), the target assembly can switch to the second target state and adjust to the second display state with the second angle range (for example, 0 to 120°). When the display assembly switches to the third display state (for example, a display area of ​​50 cm × 90 cm), the target assembly can switch to the third target state and adjust to the third display state with a third angle range (for example, 0 to 110°), and so on.Therefore, the electronic device may be able to present a variety of display modes with a better viewing angle, improve user comfort and ease of use, and meet the usage needs of different people.

[0022] When the first body 1 switches between the first and second display states, the relationship between the structures of the first body 1 can change, resulting in different display areas for the first body. This change in the relationship between the structures of the first body 1 can alter the position of the first body 1's center of gravity. If the center of gravity of the first body 1 changes, the electronic device may not be stable when placed on a desk or other support object.

[0023] Optionally, when the first body 1 switches between the first and second display states, the relationship between the structures of the first body 1 can change, causing the position of the center of gravity of the first body 1 to change. Based on the position of the center of gravity of the first body 1, the target assembly can change the rotational angular range of the first body 1 relative to the second body 2. Based on the change in the center of gravity of the first body 1, the target assembly can determine the first angular range of the first body 1 in the first display state and the second angular range of the first body 1 in the second display state. In this embodiment, the electronic device can be stably placed on a desk or other support object.If the second body 2 of the electronic device touches the desk or other support object during use, the second body 2 of the electronic device can remain stationary relative to the support object.

[0024] Alternatively, the size of the portion of the flexible screen located in the first body 1 can be adjusted by adjusting the size of the first body 1.

[0025] Optionally, the first body can have a movable structure, which may include a fixed part, a movable part, and a sliding component that drives the movable part. The movable part can shift relative to the fixed part, causing the combined size of the fixed and movable parts to change accordingly, which in turn changes the size of the first body 1. The flexible screen can adjust to the combined size of the fixed and movable parts. As the combined size of the fixed and movable parts increases, the exposed portion of the flexible screen can adjust to the increased area of ​​the first body 1, thereby increasing the display area of ​​the flexible screen.If the combined size of the fixed and movable parts decreases, the exposed portion of the flexible screen can adjust to the reduced area of ​​the first body 1, thereby decreasing the display area of ​​the flexible screen. By reducing the area of ​​the first body 1 through movement of the fixed part relative to the movable part, the area of ​​the first body 1 can be adjusted to match that of the second body 2, thus facilitating wear. By increasing the area of ​​the first body 1 by moving the fixed part relative to the movable part, making it larger than that of the second body 2, the display size can be increased.

[0026] The flexible display can be rolled up or extended using a kinematic structure to reduce or increase the display area, thus facilitating use. When the flexible display is extended, its center of gravity increases. Furthermore, the kinematic structure is typically also provided on the first body 1. This results in the first body 1 of an electronic device with a flexible display being heavier than the display of an electronic device without a flexible display. Therefore, when the center of gravity of the display increases, the electronic device may not be placed stably on a desk or other support object.

[0027] In some embodiments, the first body 1 can optionally have a first size and a first range of rotation angles relative to the second body 2 in the first display state. In the second display state, the first body 1 can have a second size and a second range of rotation angles relative to the second body 2. If the first size is smaller than the second size, the first range of angles can be larger than the second range of angles. If the first size is larger than the second size, the first range of angles can be smaller than the second range of angles. The first body 1 can have different structures in the first and second display states. Due to the changes in the relationship between the structures of the first body 1, the center of gravity of the first body 1 can also change.Optionally, as the first body 1 extends away from the rotating shaft mechanism to form the second display state, it can rotate by a defined angle relative to the second body 2. This causes the center of gravity of the first body 1 in the second display state to rise relative to the first body 1 in the first display state. The target assembly can limit the first angular range of the first body 1 in the first display state and the second angular range of the first body 1 in the second display state. This allows the electronic device to remain stable on a desk or other support object even after its center of gravity has risen, thus limiting the possibility of the electronic device tipping over.

[0028] Optionally, the first body 1 can have a fixed part and a movable part, with the movable part shifting relative to the fixed part to change the combined size of the fixed and movable parts, thereby varying the size of the first body 1. The flexible screen can adapt to the combined size of the fixed and movable parts. If the combined size of the fixed and movable parts increases, the exposed portion of the flexible screen can adapt to the increased area of ​​the first body 1, thus increasing the portion of the flexible screen available for display. If the combined size of the fixed and movable parts decreases, the exposed portion of the flexible screen can adapt to the reduced area of ​​the first body 1, thus decreasing the portion of the flexible screen available for display.The fixed part of the first body 1 can be connected to the rotating shaft mechanism. The movable part can be able to move towards the rotating shaft mechanism to form the first display state with a smaller display area, and the movable part can be able to move away from the rotating shaft mechanism to form the second display state with a larger display area. When the display assembly transitions to the first display state, the target assembly can be moved to the first target state. When the display assembly transitions to the second display state, the target assembly can be moved to the second target state. The first body 1 can have different rotation angle ranges relative to the second body 2. When the display assembly is in the first display state, the target assembly can be moved to the first target state.When the display assembly is in the second state, the target assembly can be moved into the second target state. Therefore, it may be possible to place the second body 2 of the electronic device stably on a desk or other support object, thus limiting the possibility that the end of the first body 1 furthest from the rotating shaft mechanism will touch or approach (i.e., tip over) the desk or other support object due to the effect of gravity.

[0029] Optionally, the first body 1 can form the first and second display states based on changes in the relationship between its structures, and the positions of the center of gravity of the first body 1 can change accordingly in the first and second display states. The change in the center of gravity of the first body 1 in different display states can cause the relationship between the center of gravity and the position of the support object to change. In this case, the electronic device can tip over if the relative position of the center of gravity and the support object reaches a threshold angle A. A state change of the target assembly can limit the rotation angle of the first body 1 relative to the second body 2 to a specific range, which can be configured to avoid the threshold angle A and thus prevent tipping.

[0030] In one embodiment, the first body 1 can have a first display state and a second display state, between which it can switch. The target assembly can be used to limit the rotation angle range of the first body 1 relative to the second body 2. The target assembly can have a first target state and a second target state. In the first target state, the rotation angle range of the first body 1 relative to the second body 2 can be a first angular range, and in the second target state, the rotation angle range of the first body 1 relative to the second body 2 can be a second angular range. When the display assembly switches to the first display state, the target assembly can switch to the first target state. When the display assembly switches to the second display state, the target assembly can switch to the second target state. In the first display state, the display area of ​​the display assembly can be a first area.In the second display state, the display area of ​​the display assembly can be a second surface, which may be larger than the first. The first angular range can be larger than the second angular range. As the display area of ​​the display assembly increases, the corresponding rotational angular range of the first body 1 relative to the second body 2 can become smaller. This allows the second body 2 of the electronic device to be stably placed on a desk or other support object and reduces the possibility that, due to the effect of gravity, the end of the first body 1 furthest from the rotating shaft mechanism will touch or approach (i.e., tip over) the desk or other support object after the angle between the first body 1 and the second body 2 has been set.

[0031] As in Fig. 5, which illustrates the structure of the electronic device in its first display state, where α represents the first angular range, and Fig. Figure 6, which illustrates the structure of the electronic device in its second display state, where β represents the second angular range, shows that in one embodiment the first angular range in the first display state may be larger than the second angular range in the second display state.

[0032] As in Fig. Figure 7 shows where the solid line represents the structure of the electronic device in its first display state and the solid line extended by the dashed line represents the structure of the electronic device in its second display state, β represents the maximum value of the second angular range with the first body 1 extended relative to the second body 2 in both the first and second display states.

[0033] If the second surface is larger than the first surface, rotating the first body 1 relative to the second body 2 by a defined angle can cause the center of gravity of the first body 1 to rise in the second display state compared to the first body 1 in the first display state. The center of gravity of the first body 1 in the first display state can be located at a first height position, and the center of gravity of the first body 1 in the second display state can be located at a second height position, with the second height position being higher than the first height position.If the rotation angle of the first body 1 relative to the second body is greater than 90°, and the first body 1 is rotated by the same angle in both the first and second display states, the force arm L1 of the first body 1 in the first display state can be smaller than the force arm L2 of the first body 1 in the second display state. This means that the torque of the first body 1 can be smaller in the first display state than the torque of the first body 1 in the second display state. The target assembly can limit the upper limit of the rotation angle of the first body 1 relative to the second body 2. When the display assembly transitions to the first display state, the target assembly can transition to the first target state. In the first target state, the first body 1 can rotate within a certain angular range relative to the second body 2. When the display assembly transitions to the second display state, the target assembly can transition to the second target state.In the second target state, the first body 1 can rotate within a second angular range relative to the second body 2. This allows the first body 1 to rotate within different angular ranges relative to the second body 2 depending on the position of its center of gravity in different display states. By limiting the rotation angular range of the first body 1 relative to the second body 2 using the target assembly, the electronic device can be stably placed on a desk or other support object.If the second body 2 of the electronic device touches the desk or other support object during use, the second body 2 of the electronic device can remain stationary relative to the support object, thus limiting the possibility that the end of the first body 1 furthest from the rotating shaft mechanism will touch or approach (i.e. tip over) the desk or other support object due to gravity after the angle between the first body 1 and the second body 2 has been set.

[0034] In this embodiment, if the rotation angle range of the first body 1 is within the first angular range at the maximum value of the first angular range, the electronic device can use software or mechanical structures to prevent the first body 1 from switching from the first display state to the second display state, which prevents the electronic device from tipping over due to the increase in the center of gravity of the first body 1 when the first body 1 is at the maximum value α of the first angular range.

[0035] As in Fig. Figure 8 shows where the solid line represents a schematic diagram of the electronic device in the first display state, α can represent that the opening angle of the first body 1 relative to the second body 2 can be the maximum value α of the first angular range, and the dashed line represents a schematic diagram of the structure of the electronic device after a tip-over in the first display state.

[0036] In one embodiment in conjunction with Fig. 5, Fig. 6, Fig. 7 to Fig. In 8, α optionally represents the first angular range and β the second angular range. The first body 1 can switch between the first and second display states. The target assembly can be used to limit the rotational angular range of the first body 1 relative to the second body 2, and the target assembly can have a first target state and a second target state. In the first target state, the rotational angular range of the first body 1 relative to the second body 2 can be a first range, and in the second target state, the rotational angular range of the first body 1 relative to the second body 2 can be a second range. In the second display state, when the first body 1 is open to the maximum value of the first range, the second body 2 can rotate relative to a support object, which can be an object used to support the contact of the second body 2.After the second body 2 has rotated relative to the support object, the end of the first body 1 furthest from the rotating shaft mechanism can touch the support object. In the first display state, when the first body 1 is open to the maximum value of the first range, the second body 2 can remain stationary relative to the horizontally positioned support object, and the end of the second body 2 furthest from the rotating shaft mechanism can touch the support object, thus limiting the possibility of the end of the second body 2 furthest from the rotating shaft mechanism leaving the support object. By setting the maximum value of the first range, the electronic device can be stably positioned on a desk or other support object in both the first and second display states.

[0037] Based on this, the first angular range can be larger than the second angular range, which allows the electronic device to be placed stably on a desk or other support object in both the first and second display states.

[0038] Furthermore, the second body 2 can rotate relative to the support object when the first body 1 is in the second display state and opened to the maximum value of the first angular range. When the first body 1 is in the second display state and opened to the maximum value of the second angular range, the second body 2 can remain stationary relative to the horizontally positioned support object. If the electronic device touches the support object during use, the electronic device can remain stationary regardless of the support object.

[0039] Based on this, the second body 2 can remain stationary relative to the horizontally arranged support object when the first body 1 is in the first display state and opened to the maximum value of the first angular range. When the first body 1 is in the second display state and opened to the maximum value of the second angular range, the second body 2 can remain stationary relative to the horizontally arranged support object. When the first body 1 is in the second display state and opened to the maximum value of the first angular range, the second body 2 can rotate relative to the support. The target assembly can limit the rotatable angular range of the first body 1 relative to the second body 2, such that the rotatable angular range of the first body 1 relative to the second body 2 lies within the first angular range in the first target state.In the second target state, the rotatable angular range of the first body 1 relative to the second body 2 lies within the second angular range. If the electronic device touches a support object during use, the electronic device can remain stationary regardless of the support object.

[0040] In a specific embodiment, the first angular range can be 0 to 135° and the second angular range 0 to 120°. In the first target state, the first body 1 can be opened to the maximum value of 135° of the first angular range, thus achieving the user experience of a conventional laptop. In the second target state, the first body 1 can be opened to the maximum value of 120° of the second angular range, thereby limiting the possibility that the end of the first body 1 furthest from the rotating shaft mechanism will touch or approach (i.e., tip over) a desk or other support object under the influence of gravity in the second target state. This satisfies the user's need for a larger screen while simultaneously limiting the possibility of tipping over.

[0041] In a specific embodiment, the electronic device can comprise a first body 1, a second body 2, and a target assembly. The first body 1 can include a display unit that can have a first display state and a second display state, between which it is possible to switch. The display area of ​​the display assembly in the first display state can differ from the display area of ​​the display assembly in the second display state. The second body 2 can be rotatably connected to the first body 1. The target assembly can be used to limit the rotational angular range of the first body 1 relative to the second body 2. The target assembly can have a first target state and a second target state. In the first target state, the rotational angular range of the first body 1 relative to the second body 2 can be the first angular range.In the second target state, the rotation angle range of the first body 1 relative to the second body 2 can be the second angle range. The second angle range can differ from the first angle range. When the display assembly transitions to the first display state, the target assembly can transition to the first target state. When the display assembly transitions to the second display state, the target assembly can transition to the second target state, thus enabling the electronic device to have different rotation angle ranges of the first body 1 relative to the second body 2 in different display states.Users can adjust the rotation angle of the first body 1 relative to the second body 2 based on the different display areas of the first body 1. This allows the electronic device to offer a better viewing angle when presenting a variety of display modes, improving user comfort and convenience and meeting the needs of different users. A change in the state of the target assembly can limit the rotation angle of the first body 1 relative to the second body 2 to a specific range.

[0042] As in Fig. 1, Fig. 2, Fig. 3 to Fig. As shown in Figure 4, the target assembly can comprise a drive component 34 and a brake component 30. The drive component 34 can comprise a motor, a gear, and a rotary shaft mechanism. The brake component 30 can be in a mating relationship with the rotary shaft mechanism. Optionally, if the brake component 30 and the rotary shaft mechanism are in a first mating relationship, the target assembly can be in the first target state. If the brake component 30 and the rotary shaft mechanism are in a second mating relationship, the target assembly can be in the second target state. The drive component 34 can drive the brake component 30 to switch between the first and second mating relationships with the rotary shaft mechanism.

[0043] The drive component 34 and the brake component 30 can be interconnected, and the drive component 34 can be configured to drive the brake component 30, causing the brake component 30 to change its position to limit the opening angle of the first body 1 relative to the second body 2. In the first target state, the first body 1 can rotate within the first angular range relative to the second body 2, and in the second target state, the first body 1 can rotate within a second angular range. A change in the position of the brake component 30 can cause the rotational angular range of the first body 1 relative to the second body 2 to switch between the first and second angular ranges.In this embodiment, the brake component 30 can be driven by the drive component 34 to change its position, thereby limiting the rotation angle range of the first body 1 relative to the second body 2. When the display assembly switches to the first display state, the target assembly can switch to the first target state, and the rotation angle range of the first body 1 relative to the second body 2 can be the first angle range. When the display assembly switches to the second display state, the target assembly can switch to the second target state, and the rotation angle range of the first body 1 relative to the second body 2 can be the second angle range.This allows the electronic device to exhibit different rotation angle ranges of the first body 1 relative to the second body 2 in various display states. This makes it easier for users to adjust the angle of the first body 1 of the electronic device according to their needs and allows users to find the appropriate operating angle of the first body 1 of the electronic device in different display states, thereby improving the user experience. The electronic device can also be placed stably on a desk or other support object. That is, if the electronic device touches the support object during use, the electronic device can remain in a static state regardless of the support object.

[0044] In one embodiment, the electronic device can comprise a first body 1, a second body 2, and a target assembly. The first body 1 can comprise a display assembly and can have a first display state and a second display state, between which it is possible to switch. The target assembly can have a first target state and a second target state.

[0045] The target assembly can comprise a drive component 34, a brake component 30, and a rotary shaft mechanism. The drive component 34 and the brake component 30 can be transmissionally connected. The drive component 34 can be used to drive the brake component 30. The rotary shaft mechanism can comprise a first rotary component 31, a second rotary component 32, and a connecting assembly 33. The first rotary component 31 and the second rotary component 32 can be rotaryally connected by the connecting assembly 33. The first rotary component 31 can be connected to the first body 1, and the second rotary component 32 can be connected to the second body 2. Optionally, the first rotary component 31 and the first body 1 can be connected by fasteners or by welding, and the second rotary component 32 and the second body 2 can be connected by fasteners or by welding.Optionally, the first rotary component 31 can have a first rotating shaft and a first connecting component arranged on the first rotating shaft. The first connecting component can be rotatably connected to the first rotating shaft and can be used to connect to the first body 1. The second rotary component 32 can have a second rotating shaft and a second connecting component arranged on the second rotating shaft. The second connecting component can be rotatably connected to the second rotating shaft and can be used to connect to the second body 2. The connecting assembly can be a gear assembly or a hinge. The connecting assembly can be arranged on the first rotating shaft and the second rotating shaft and can be connected to the first connecting component and the second connecting component.The brake component 30 can be arranged coaxially with the first rotary component 31, and the axial direction of the brake component 30 can lie on the same line as the axial direction of the first rotary component 31. Optionally, the direction of movement of the brake component 31 can be the same as the axial direction of the first rotary component 31. The first rotary component 31 can have an abutment component 311. The drive component 34 can be used to drive the brake component 30 to move axially along the first rotary component 31, thus enabling the brake component 30 to move towards or away from the first rotary component 31 along its axis. This can allow the brake component 30 to be in contact with the contact component 311 in the first position to limit the rotation angle of the first rotary component 31, or to be detached from the contact component 311 in the second position.When the brake component 30 is in the first position, it can be in contact with the contact component 311, allowing the target assembly to move into the second target state. When the brake component 30 is in the second position, it can be detached from the contact component 311, allowing the target assembly to move into the first target state. When the brake component 30 is detached from the contact component 311, the target assembly cannot touch the contact component 311 during the rotation of the first body 1 relative to the second body 2. In this embodiment, the drive component 34 can drive the brake component 30, allowing the position of the brake component 30 to change, thereby changing the target state of the target assembly.When the display assembly is moved to the first display state, the brake component 30 can be in the second position, the target assembly can be moved to the first target state, and the first body 1 can rotate within the first angular range relative to the second body 2. When the display assembly is moved to the second display state, the brake component 30 can be in the first position, the target assembly can be moved to the second target state, and the first body 1 can rotate within the second angular range relative to the second body 2. This allows the electronic device to rotate within different angular ranges relative to the second body 2 in various display states, enabling it to be stably positioned on a desk or other support object.This means that if the electronic device touches a support object during use, the electronic device can maintain an independent static state relative to the support object.

[0046] Optionally, the first rotating component 31 can have a first rotating shaft and a first connecting plate. The first connecting plate can be attached to the first rotating shaft and can be attached to a mounting section. A clamping plate can be attached to the first rotating shaft and can have a clamping section.

[0047] The second rotating component 32 can have a second rotating shaft and a second connecting plate. The second connecting plate can be attached to the second rotating shaft and the second connecting plate can be attached to the second body 2. Optionally, several gears can mesh to allow the second rotating shaft to rotate around the first rotating shaft.

[0048] Optionally, the first rotating component 31 and the second rotating component 32 can be rotatably connected to a connecting assembly 33. Optionally, the connecting assembly 33 can have several meshing gears.

[0049] In one embodiment, the electronic device can comprise a first body 1, a second body 2, and a target assembly. The first body 1 can include a display assembly and can have a first display state and a second display state, between which it can switch. The target assembly can have a first target state and a second target state. The target assembly can include a drive component 34, a brake component 30, and a rotary shaft mechanism. The drive component 34 and the brake component 30 can be transmissionally connected. The drive component 34 can be used to drive the brake component 30. The rotary shaft mechanism can include a first rotary component 31, a second rotary component 32, and a connecting assembly 33. The first rotary component 31 and the second rotary component 32 can be rotaryally connected via the connecting assembly 33.The first rotating component 31 can be connected to the first body 1, and the second rotating component 32 can be connected to the second body 2. The first rotating component 31 can be provided with a contact component 311. The electronic device can further include a control unit for generating a first control signal or a second control signal. The control unit can be connected to the drive component 34, and the drive component 34 can be used, according to the first control signal, to drive the brake component 30 to move to the first position, so that the brake component 30 contacts the contact component 311 to limit the rotation angle of the first rotating component 31, and the angle of maximum extension of the first body 1 relative to the second body 2 is the second angle.The drive component 34 can also be used, according to the second control signal, to drive the brake component 30 to move to the second position, so that the brake component 30 releases from the contact component 311 and the angle of maximum extension of the first body 1 relative to the second body 2 is the first angle. Optionally, the first angle can be the maximum value of the first angle range and the second angle the maximum value of the second angle range. The brake component 30 can be arranged coaxially with the first rotary component 31, and the first rotary component 31 can be provided with the contact component 311.When the control unit generates the first control signal, the drive component 34 can drive the brake component 30 to move towards the first position, allowing the brake component 30 to contact the abutment component 311, and the target assembly switches to the second target state, allowing the first body 1 to have a maximum opening angle relative to the second body 2, which is equal to the second angle. When the control unit generates the first control signal, the drive component 34 can drive the support component to move towards the second position, allowing the brake component 30 to detach from the abutment component 311, and the target assembly switches to the first target state, allowing the first body 1 to have a maximum opening angle relative to the second body 2, which is equal to the first angle.In this embodiment, the control unit can control the drive component 34 to drive the brake component 30, thereby changing the position of the brake component 30 and switching the target state of the target assembly. When the display assembly switches to the first display state, the brake component 30 can be in the second position, the target assembly can switch to the first target state, and the first body 1 can rotate within the first angular range relative to the second body 2. When the display assembly switches to the second display state, the brake component 30 can be in the first position, the target assembly can switch to the second target state, and the first body 1 can rotate within the second angular range relative to the second body 2.Therefore, the rotational angular range of the first body 1 relative to the second body 2 can differ when the electronic device is in various display states, allowing it to be placed stably on a desk or other support object. This means that even if the electronic device touches the support object during use, it can maintain an independent static state with the support object.

[0050] Optionally, pressing a button on the electronic device can generate a control signal corresponding to the button press. This control signal can be a first, second, or third control signal. Based on this control signal, the drive component 34 can perform a corresponding control operation. Based on the first control signal, the drive component 34 can drive the brake component 30 to move towards the first position, allowing the brake component 30 to contact the bearing component 311. This limits the rotation angle of the first rotating component 31 and enables the first body 1 to have a maximum opening angle relative to the second body 2, which is equal to the second angle.

[0051] Based on the foregoing, the contact component 311 can have a contact wall 311a. When the control unit generates the first control signal, the drive component 34 can drive the brake component 30 to move toward the first position so that the brake component 30 can contact the contact wall 311a, and the target assembly can move into the second target state, allowing the first body 1 to have a maximum opening angle relative to the second body 2, which is equal to the second angle. The contact wall 311a can contact the brake component 30 when the first body 1 is opened to the second angle relative to the second body 2. This can allow the first body 1 to rotate to the maximum angle relative to the second body 2 when the electronic device is in the second display state.This can allow the second body 2 to remain stationary relative to a horizontally arranged support object when the electronic device is unfolded at the second angle. If the second body 2 of the electronic device touches a support object during use, the possibility of the end of the first body 1 furthest from the rotating shaft mechanism touching or approaching (i.e., tipping over) a desk or other support object due to gravity can be reduced, thus allowing the electronic device to remain stably placed on a desk or other support object.

[0052] In one embodiment, the electronic device can comprise a first body 1, a second body 2, and a target assembly. The first body 1 can comprise a display assembly and can have a first display state and a second display state, between which it can switch. The target assembly can have a first target state and a second target state. The target assembly can comprise a drive component 34, a brake component 30, a rotary shaft mechanism, a first support component 35, and / or a second support component 39. The drive component 34 and the brake component 30 can be transmissionally connected and can be used to drive the brake component 30. The rotary shaft mechanism can comprise a first rotary component 31, a second rotary component 32, and a connecting assembly 33. The first rotary component 31 and the second rotary component 32 can be rotaryally connected via the connecting assembly 33.The first rotating component 31 can be connected to the first body 1, and the second rotating component 32 can be connected to the second body 2. The first rotating component 31 can be provided with a contact component 311. The brake component 30 can be arranged coaxially with the first rotating component 31, and the drive component 34 can be used to drive the brake component 30 to move axially along the first rotating component 31, such that in the first position the brake component 30 is in contact with the contact component 311 to limit the angle of rotation of the first rotating component 31, and in the second position the brake component 30 is separated from the contact component 311. The first support component 35 can be connected to the second body 2. Optionally, the first support component 35 and the second body 2 can be connected by means of fasteners.The drive component 34 can be installed on the first support component 35, and the output end of the drive component 34 can be connected to the screw rod 38 to cause the screw rod 38 to rotate. The first support component 35 can be provided with a guide pin 36, and the guide pin 36 can be slidably connected to a slide 37. The slide 37 can be threaded to the screw rod 38, and the slide 37 can be connected to the brake component 30. When the drive component 34 rotates the screw rod 38, the slide 37, which is located on the screw rod 38, can move axially along the screw rod 38. When the slide 37 moves in the direction of the first rotating component 31, the slide 37 can drive the brake component 30, causing the brake component 30 to move to the first position, which causes the brake component 30 to rest against the bearing component 311.The target assembly can switch to the second target state, so that the maximum opening angle of the first body 1 relative to the second body 2 can be the maximum value of the second angle range. Optionally, the slide 37 and the brake component 30 can be connected by a connecting rod 40. If the brake component 30 is disconnected from the contact component 311, the target assembly can switch to the first target state, so that the maximum opening angle of the first body 1 relative to the second body 2 can be the maximum value of the first angle range. The slide 37 can move with the guide pin 36, which allows the slide 37 to move axially along the guide pin 36. This improves the stability of the slide 37's movement, thereby improving the stability of the brake component 30 and the stability of the target assembly when switching between the first and second target states.

[0053] Optionally, the second support component 39 can be connected to the second body 2 and provided with a guide hole. The brake component 30 can slidably engage in the guide hole, allowing it to move along the hole, thereby improving the stability of the brake component 30 and the stability of the target assembly when switching between the first and second target states.

[0054] Based on the foregoing, the brake component 30 can have a limiter arranged at an end of the brake component 30 facing the first rotating component 31. The limiter can be in contact with the contact component 311 in the first position and can be released from the contact component 311 in the second position. When the drive component 34 actuates the brake component 30 to move to the first position, the limiter can be in contact with the contact component 311 and the target assembly can move into the second target state, thereby enabling the maximum opening angle of the first body 1 relative to the second body 2 to be the maximum value of the second angular range.When the drive component 34 drives the brake component 30 to move to the second position, the limiter can detach from the contact component 311 and the target assembly switches to the first target state, thus enabling the maximum opening angle of the first body 1 relative to the second body 2 to be the maximum value of the first angle range.

[0055] In one embodiment as in Fig. As shown in Figure 9, the electronic device can comprise a first body 1, a second body 2, and a target assembly. The first body 1 can have a display unit that can switch between a first display state and a second display state. The target assembly can have a first target state and a second target state. The target assembly can comprise a drive component 34, a first rotating shaft, a second rotating shaft, and a control unit. The first rotating shaft can be provided with a first gear 41 that can be connected to the first body 1. The second rotating shaft can be provided with a second gear 42 that can be connected to the second body 2. The first gear 41 and the second gear 42 can be in transmission connection, which allows the first body 1 to rotate relative to the second body 2.Optionally, the first gear 41 and the second gear 42 can be connected by several interlocking gears, which allows the first body 1 and the second body 2 to rotate synchronously in opposite directions.

[0056] The output end of the drive component 34 can be in drive connection with the first gear 41 or the second gear 42. Alternatively, the drive component 34 can be a drive motor with a drive gear 44 mounted at its output end. The drive gear 44 can mesh with either the first gear 41 or the second gear 42.

[0057] The control unit can be configured to generate a third or a fourth control signal. The drive component 34 can be connected to the control unit and configured to drive the first gear 41 or the second gear 42 based on the third or the fourth control signal.

[0058] In one embodiment, the drive component 34 can, for example, drive the first gear 41. When the control unit generates the third control signal, the drive component 34 can drive the drive gear 44 to rotate the first gear 41, which rotates by a first angle. When the first gear 41 rotates by the first angle, the first body 1 can rotate relative to the second body 2. When the control unit generates the fourth control signal, the drive component 34 can drive the drive gear 44 to rotate the first gear 41, which rotates by a second angle, and the first body 1 rotates relative to the second body 2.In this embodiment, the drive component 34 can drive the first gear 41 or the second gear 42 to rotate by different angles, thereby enabling the first body 1 to exhibit different rotatable angles relative to the second body 2 in different display states of the electronic device. This not only facilitates user adjustment of the angle of the first body 1 of the electronic device according to usage requirements, allowing the user to find the appropriate angle for the first body 1 of the electronic device in different display states, thus improving the user experience of the electronic device, but also enables the electronic device to be placed stably on a desk or other support object.This means that if the electronic device touches the support object during use, the electronic device can remain stationary regardless of the support object.

[0059] In one embodiment as in Fig. As shown in Figure 10, the electronic device can have a first body 1, a second body 2, and a target assembly. The first body 1 can have a display unit that can have a first display state and a second display state, between which it is possible to switch. The target assembly can have a first target state and a second target state. The target assembly can have a first rotating shaft, a second rotating shaft, and a drive component 34. The first rotating shaft can be provided with a fourth gear 46 and a fifth gear 47, each of which is fixedly connected to the first rotating shaft and the first body 1, respectively.

[0060] The second rotating shaft can be equipped with a third gear that is slidably engaged with the second rotating shaft. The third gear can be connected to the second body 2 and can be movable relative to the second body 2 along the axis of the second rotating shaft. Alternatively, the second rotating shaft can be fixed to the second body 2, and the third gear can be movable along the axis of the second rotating shaft. When the third gear rotates, it can cause the second body 2 to rotate. Alternatively, the second rotating shaft can be fixed to the second body 2, and the third gear can be movable along the axis of the second rotating shaft. The third gear can rotate relative to the second rotating shaft.

[0061] The fourth gear 46 can be provided on its circumferential side with a first toothed structure 461 and a first stop 462. The first stop 462 can be arranged at both ends of the first toothed structure 461. The fifth gear 47 can be provided with a second toothed structure 471 and a second stop 472. The second stop 472 can be arranged at both ends of the second toothed structure. The drive element 34 can be connected to the third gear and drive the third gear to engage with the first toothed structure 461 or the second toothed structure 471, thereby rotating the first body 1 relative to the second body 2. Optionally, the drive element 34 can have a movable component that drives the third gear to move axially along the second rotating shaft. The movable component can be a cylinder or another structure.The drive component 34 can include a drive motor that drives the third gear to rotate. Optionally, after the third gear has engaged with the first toothed structure 461, the drive component 34 can drive the third gear to rotate the fourth gear 46. Alternatively, after the third gear has engaged with the second toothed structure 471, the drive component 34 can drive the third gear to rotate the fifth gear 47.

[0062] The number of teeth in the first toothed structure 461 can differ from the number of teeth in the second toothed structure 471. This allows the first body 1 to rotate within the first angular range relative to the second body 2 when the third gear engages the first toothed structure 461, and allows the first body 1 to rotate within the second angular range relative to the second body 2 when the third gear engages the second toothed structure 471. When the third gear engages the first toothed structure 461, the display assembly can switch to the first display state, and when the third gear engages the second toothed structure 471, the display assembly can switch to the second display state.This not only facilitates user adjustment of the angle of the first body 1 of the electronic device according to usage needs, allowing the user to find the appropriate angle for the first body 1 of the electronic device in different display states, thereby improving the user experience of the electronic device, but also allows the electronic device to be placed stably on a desk or other support object. That is, if the electronic device touches the support object during use, the electronic device can remain stationary regardless of the support object.
