DETAILED DESCRIPTION

[0048] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0049] The electronic device generally includes a first body, a second body, and a hinge mechanism connecting the first body and the second body, wherein the hinge mechanism is connected to the first body and the second body respectively to achieve an adjustable opening and closing angle of the first body relative to the second body. The first body and the second body can adjust the angle so that when the electronic device contacts a supporting object, the electronic device can remain independent and still, and can also be convenient for users to use.

[0050] In some embodiments, the second body contacts the supporting object, and the second body can support the first body as a bracket. The first body can be a body that can receive operations from the operating body, such as a control panel, a display interface, etc. When using an electronic device, the user can place the electronic device on a desktop or other supporting object, with the second body of the electronic device facing the desktop or other supporting object. The electronic device also includes a flexible screen for display, and the flexible screen can be provided on the first body and / or the second body. The flexible screen has a bendable property and can adaptively deform with the sliding position while ensuring the performance of use.

[0051] The inventor of the present application has discovered that as electronic devices become more multifunctional, user demands are also increasing. The display modes of electronic devices in traditional technologies are relatively single and cannot meet user demands.

[0052] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the electronic device provided by the embodiment of the present disclosure may include a first body 1, a second body 2 and a target component; the first body 1 and the second body 2 form two parts of the electronic device that can be opened and closed. The first body 1 and the second body 2 may be components connected to the hinge mechanism respectively, and the hinge mechanism may drive the first body 1 to rotate in a direction close to or away from the second body 2 to realize the opening and closing of the electronic device. Taking a laptop computer as an example, the first body may be a screen component, and the second body may be a host component.

[0053] The first body 1 may include a display component, where the display component may be a device used by the electronic device for display. For example, the display component may be a display screen.

[0054] The first body 1 may have a switchable first display state and a second display state. The first body 1 has at least two display states, namely the first display state and the second display state, and the first body 1 may switch between the first display state and the second display state. Optionally, the first body 1 may also include a third display state, and the third display state may be a state between the first display state and the second display state. Optionally, in the first display state and the second display state, the first body 1 may have different structural relationships, respectively. Since the relationship between the structures of the first body 1 itself changes, the center of gravity position of the first body 1 will also change accordingly. Optionally, in the first display state and the second display state, the display area of ​​the first body 1 as a display surface may be different.

[0055] The display area of ​​the display component in the first display state may be different from the display area of ​​the display component in the second display state. In the first display state and the second display state, the display component has different display areas. For example, it can be considered that in the first display state and the second display state, the display output area of ​​the display screen has different areas, so as to facilitate users to adjust the display state of the electronic device based on different usage requirements and improve the user's experience of using the electronic device.

[0056] The target component may be arranged on the rotating shaft mechanism, or may be in a matching relationship with the rotating shaft mechanism.

[0057] Optionally, the target component is in a first target state when it is in a first matching relationship with the shaft mechanism, and is in a second target state when it is in a second matching relationship with the shaft mechanism. Optionally, the target component may have a matching relationship with the first body 1, and is in a first target state when it is in a first matching relationship with the first body 1, and is in a second target state when it is in a second matching relationship with the first body 1.

[0058] The second body 2 can be rotatably connected to the first body 1; the target component is used to limit the rotatable angle range of the first body 1 relative to the second body 2, and the target component can have a first target state and a second target state. The target component can change state. The main function of the target component is to limit or control the rotatable angle range of the first body 1 of the electronic device relative to the second body 2, so as to facilitate users to adjust the angle of the first body 1 of the electronic device based on different usage requirements, so that users can find the appropriate usage angle of the first body 1 of the corresponding electronic device in different display states, thereby improving the user's experience of using the electronic device.

[0059] In the first target state, the rotatable angle range of the first body 1 relative to the second body 2 may be a first angle range, and the first angle range may be any angle between 0° and the maximum angle at which the first body 1 rotates relative to the second body 2 in the first target state. In the second target state, the rotatable angle range of the first body 1 relative to the second body 2 may be a second angle range, and the second angle range may be any angle between 0° and the maximum angle at which the first body 1 rotates relative to the second body 2 in the second target state. The second angle range is different from the first angle range. The target component can limit or control the upper limit of the rotatable angle of the first body 1 relative to the second body 2, so that the electronic device can be stably placed on a desktop or a supporting object in different postures. For example, in the first target state, the upper limit of the first angle range is 135°, and in the second target state, the upper limit of the second angle range is 120°. In the first target state, the upper limit of the rotatable angle of the first body 1 relative to the second body 2 is 135°, and in the second target state, the upper limit of the rotatable angle of the first body 1 relative to the second body 2 is 120°, etc.

[0060] When the first body 1 switches between the first display state and the second display state, the relationship between the structures of the first body 1 itself will change. The display area of ​​the first body is different. The rotatable angle range of the first body 1 relative to the second body 2 is limited by the target component. When the display component switches to the first display state, the target component switches to the first target state. In the first target state, the rotatable angle range of the first body 1 relative to the second body 2 can be the first angle range. When the display component switches to the second display state, the target component switches to the second target state. In the second target state, the rotatable angle range of the first body 1 relative to the second body 2 can be the second angle range, so that the electronic device can have different rotatable angle ranges of the first body 1 relative to the second body 2 when the display area is different. In this embodiment, the rotatable angle range of the first body 1 relative to the second body 2 is limited by the target component, so that the user can automatically adjust the rotatable angle to adapt to different display states according to the needs of different display states. In this embodiment, a variety of display modes can be formed by corresponding different display areas of the first body 1 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, so that the electronic device presents a variety of display modes. In different display modes, the user can limit the rotation of the first body 1 relative to the second body 2 within different rotation angle ranges. The user can adjust the rotation angle range he wants in a certain display mode by himself, so that different users can obtain personalized, adjustable viewing angles that match the display mode, improve the user's operation comfort and convenience of use, and meet the usage needs of different people.

[0061] Optionally, when the display component switches to a first display state (such as a display area of ​​50CM*70CM), the target component automatically switches to a corresponding first target state, and adapts to the first display state with a first angle range (such as 0-130°); when the display component switches to a second display state (such as a display area of ​​50CM*80CM), the target component switches to a second target state, and adapts to the second display state with a second angle range (such as 0-120°); when the display component switches to a third display state (such as a display area of ​​50CM*90CM), the target component switches to a third target state, and adapts to the third display state with a third angle range (such as 0-110°), etc., so that the electronic device can present a variety of display modes with a better viewing angle, improve the user's operation comfort and convenience of use, and meet the usage needs of different people.

[0062] When the first body 1 switches between the first display state and the second display state, the relationship between the structures of the first body 1 itself will change, so that the display area of ​​the first body will be different. The change in the relationship between the structures of the first body 1 itself will cause the center of gravity position of the first body 1 to change. When the center of gravity of the first body 1 changes, there is a possibility that the electronic device cannot be stably placed on a desktop or other supporting objects.

[0063] Optionally, when the first body 1 switches between the first display state and the second display state, the relationship between the structures of the first body 1 itself changes, so that the center of gravity position of the first body 1 changes, and the target component can change the rotatable angle range of the first body 1 relative to the second body 2 according to the center of gravity position of the first body 1. The target component can determine the first angle range of the first body 1 in the first display state and the second angle range of the first body in the second display state according to the change in the center of gravity position of the first body 1. This embodiment can stably place the electronic device on a desktop or other supporting object, and when the second body 2 of the electronic device contacts the desktop or other supporting object during use, the second body 2 of the electronic device can remain relatively stationary with the supporting object.

[0064] Optionally, the size of the portion of the flexible screen located on the first body 1 may be adjusted by adjusting the size of the first body 1 .

[0065] Optionally, the first body may include a motion structure, and the motion structure may include a fixed part, a sliding part, and a sliding member driving the sliding part. The sliding part slides relative to the fixed part, so that the overall size of the fixed part and the sliding part can change accordingly, that is, the size of the first body 1 can be changed. The flexible screen can adapt to the overall size of the fixed part and the sliding part. When the overall size of the fixed part and the sliding part increases, the exposed part of the flexible screen adapts to the increased area of ​​the first body 1, so that the part of the flexible screen used for display can be increased. When the overall size of the fixed part and the sliding part decreases, the exposed part of the flexible screen adapts to the reduced area of ​​the first body 1, so that the part of the flexible screen used for display can be reduced. When the area of ​​the first body 1 is reduced by the movement of the fixed part relative to the sliding part, the area of ​​the first body 1 can be adapted to the second body 2, which is convenient for carrying; when the area of ​​the first body 1 is larger than the area of ​​the second body 2 by the movement of the fixed part relative to the sliding part, the area of ​​the first body 1 is increased, and the display size of the display screen can be increased.

[0066] The flexible screen can be rolled in and spread out through the motion structure to reduce or enlarge the display area for easy use. The inventor of the present application found that after the flexible display screen is spread out, the center of gravity of the display screen will become higher. At the same time, the motion structure is generally also arranged on the first body 1, which causes the first body 1 of the electronic device with a flexible display screen to be heavier than the display screen of the electronic device without a flexible display screen. Therefore, when the center of gravity of the display screen becomes higher, there is a possibility that the electronic device cannot be stably placed on a desktop or other supporting objects.

[0067] Optionally, in some embodiments, in the first display state of the electronic device of the present application, the size of the first body 1 may be the first size, and the rotatable angle range of the first body 1 relative to the second body 2 may be the first angle range; in the second display state, the size of the first body 1 may be the second size, and the rotatable angle range of the first body 1 relative to the second body 2 may be the first angle range. When the first size is smaller than the second size, the first angle range may be larger than the second angle range; when the first size is larger than the second size, the first angle range may be smaller than the second angle range. In the first display state and the second display state, the first body 1 may have different structures respectively, and the relationship between the structures of the first body 1 itself changes, thereby causing the center of gravity position of the first body 1 to change accordingly. Optionally, when the first body 1 is extended in the direction away from the rotating shaft mechanism to form the second display state, the first body 1 rotates relative to the second body 2 by a set angle, so that the center of gravity of the first body 1 in the second display state is raised relative to the first body 1 in the first display state, and the first angle range of the first body 1 in the first display state and the second angle range of the first body in the second display state are limited by the target component, so that the center of gravity of the electronic device can be stably placed on a desktop or other supporting objects after the center of gravity of the electronic device is raised, thereby reducing the possibility of the electronic device tipping over.

[0068] Optionally, the first body 1 may include a fixed portion and a sliding portion, and the sliding portion may slide relative to the fixed portion, so that the overall size of the fixed portion and the sliding portion may change accordingly, that is, the size of the first body 1 may be changed. The flexible screen may adapt to the overall size of the fixed portion and the sliding portion. When the overall size of the fixed portion and the sliding portion increases, the exposed portion of the flexible screen adapts to the increased area of ​​the first body 1, thereby increasing the portion of the flexible screen used for display. When the overall size of the fixed portion and the sliding portion decreases, the exposed portion of the flexible screen adapts to the reduced area of ​​the first body 1, thereby reducing the portion of the flexible screen used for display. The fixed portion of the first body 1 may be connected to a rotating shaft mechanism, and the sliding portion may move toward the direction close to the rotating shaft mechanism to form a first display state with a smaller display area, and the sliding portion may move toward the direction away from the rotating shaft mechanism to form a second display state with a larger display area. When the display component switches to the first display state, the target component may switch to the first target state, and when the display component switches to the second display state, the target component may switch to the second target state, and the first body 1 may have a different rotatable angle range relative to the second body 2. When the display component is in the first display state, the target component can be switched to the first target state, and when the display component is in the second state, the target component can be switched to the second target state, so that the second body 2 of the electronic device can be stably placed on a desktop or other supporting object, reducing the possibility of the first body 1 contacting or approaching the desktop or other supporting objects (i.e., tipping over) at the end away from the hinge mechanism under the action of gravity.

[0069] Optionally, the first body 1 can form a first display state and a second display state due to changes in the relationship between its own structures, and the position of the center of gravity of the first body 1 in the first display state and the second display state also changes accordingly. The change in the position of the center of gravity of the first body 1 in different display states causes the relationship between the center of gravity and the position of the support body to change; in this case, if the relative position of the center of gravity and the support body reaches a threshold angle A, it will cause the electronic device to tip over, and the target component switching state can limit the rotation angle of the first body 1 relative to the second body 2 to a certain range, which can be configured to avoid the above-mentioned threshold angle A, thereby avoiding tipping.

[0070] In one embodiment, the first body 1 may have a switchable first display state and a second display state. The target component is used to limit the rotatable angle range of the first body 1 relative to the second body 2, and the target component may have a first target state and a second target state. In the first target state, the rotatable angle range of the first body 1 relative to the second body 2 may be a first angle range, and in the second target state, the rotatable angle range of the first body 1 relative to the second body 2 may be a second angle range. When the display component switches to the first display state, the target component switches to the first target state, and when the display component switches to the second display state, the target component switches to the second target state. In the first display state, the display area of ​​the display component may be a first area, and in the second display state, the display area of ​​the display component may be a second area, and the second area is larger than the first area; the first angle range is larger than the second angle range. When the display area of ​​the display component increases, the corresponding rotatable angle range of the first body 1 relative to the second body 2 becomes smaller, so that the second body 2 of the electronic device can be stably placed on a desktop or other supporting object, reducing the possibility that the end of the first body 1 away from the hinge mechanism will contact or approach the desktop or other supporting objects (i.e., tip over) under the action of gravity after the angle between the first body 1 and the second body 2 is adjusted.

[0071] refer to Figure 5 and Figure 6 , Figure 5 A schematic diagram showing a structure of a first display state of an electronic device may be shown; α may represent a first angle range; Figure 6 The schematic diagram of the structure of the electronic device in the second display state is shown in FIG. β can represent the second angle range. Figure 5 and Figure 6 , the first angle range in the first display state is greater than the second angle range in the second display state.

[0072] refer to Figure 7 , Figure 7 The solid line in the middle may represent a schematic diagram of the electronic device in the first display state. Figure 7 The solid line plus the dotted line are extended to represent a schematic diagram of the second display state of the electronic device, and β represents that the unfolding angle of the first body 1 relative to the second body 2 in the first display state and the second display state is the maximum value β of the second angle range.

[0073] When the second area is greater than the first area, the first body 1 rotates relative to the second body 2 at a set angle, so that the center of gravity of the first body 1 in the second display state rises relative to the first body 1 in the first display state. The center of gravity position of the first body 1 in the first display state can be the first height position, and the center of gravity position of the first body 1 in the second display state can be the second height position. The height of the second height position is higher than the first height position. When the rotation angle of the first body 1 relative to the second body is greater than 90° and the first body 1 rotates at the same angle in the first display state and the second display state, the force arm L1 of the first body 1 in the first display state is less than the force arm L2 of the first body 1 in the second display state, that is, the torque of the first body 1 in the first display state is less than the torque of the first body in the second display state. The target component can limit the upper limit of the rotatable angle of the first body 1 relative to the second body 2. When the display component switches to the first display state, the target component switches to the first target state. In the first target state, the rotatable angle range of the first body 1 relative to the second body 2 can be the first angle range. When the display component switches to the second display state, the target component switches to the second target state. In the second target state, the rotatable angle range of the first body 1 relative to the second body 2 can be the second angle range, so that when the center of gravity of the first body 1 is different in different display states of the electronic device, the rotatable angle range of the first body 1 relative to the second body 2 is different. By limiting the rotatable angle range of the first body 1 relative to the second body 2 by the target component, the electronic device can be stably placed on a desktop or other supporting object. When the second body 2 of the electronic device contacts the desktop or other supporting object during use, the second body 2 of the electronic device can remain relatively stationary with the supporting object, reducing the possibility that the end of the first body 1 away from the rotating shaft mechanism contacts or approaches the desktop or other supporting object (i.e., tipping) under the action of gravity after the angle between the first body 1 and the second body 2 is adjusted.

[0074] In this embodiment, when the rotatable angle range of the first body 1 at the maximum value of the first angle range may be within the first angle range, the electronic device can limit the first body 1 from changing from the first display state to the second display state through software or mechanical structure, thereby avoiding the possibility of the electronic device 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 angle range.

[0075] refer to Figure 8 As shown, Figure 8 The solid line in the middle may represent a schematic diagram of the electronic device in the first display state, α represents that in the first display state, the unfolding angle of the first body 1 relative to the second body 2 may be the maximum value α of the first angle range, Figure 8 The middle dotted line may represent a schematic diagram of the structure of the electronic device after it is tipped over in the first display state.

[0076] In one embodiment, in combination Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, optionally, α represents the first angle range, and β represents the second angle range. The first body 1 can switch between the first display state and the second display state. The target component is used to limit the rotatable angle range of the first body 1 relative to the second body 2, and the target component can have a first target state and a second target state. In the first target state, the rotatable angle range of the first body 1 relative to the second body 2 can be a first angle range, and in the second target state, the rotatable angle range of the first body 1 relative to the second body 2 can be a second angle range. When the first body 1 is in the second display state, when it is opened to the maximum value of the first angle range, the second body 2 rotates relative to the support body, and the support body can be an object used to support the contact of the second body 2. After the second body 2 rotates relative to the support body, the end of the first body 1 away from the shaft mechanism can contact the support body; when the first body 1 is in the first display state, when it is opened to the maximum value of the first angle range, the second body 2 can be relatively still with the horizontally arranged support body, and the end of the second body 2 away from the shaft mechanism can contact the support body, reducing the possibility of the end of the second body 2 away from the shaft mechanism leaving the support body. By setting the maximum value of the first angle range, the electronic device can be stably placed on a desktop or other supporting objects when the electronic device is in the first display state and the second display state.

[0077] On this basis, the first angle range is greater than the second angle range, so that the electronic device can be stably placed on a desktop or other supporting objects when the electronic device is in the first display state and the second display state.

[0078] On this basis, when the first body 1 is in the second display state and is opened to the maximum value of the first angle range, the second body 2 rotates relative to the support body; when the first body 1 is in the second display state and is opened to the maximum value of the second angle range, the second body 2 can be relatively still with respect to the horizontally arranged support body. When the electronic device contacts the support object during use, the electronic device can maintain an independent still state with the support object.

[0079] On this basis, when the first body 1 is in the first display state and is opened to the maximum value of the first angle range, the second body 2 can be relatively still with the horizontally arranged support body; when the first body 1 is in the second display state and is opened to the maximum value of the second angle range, the second body 2 can be relatively still with the horizontally arranged support body; when the first body 1 is in the second display state and is opened to the maximum value of the first angle range, the second body 2 rotates relative to the support body; the target component is used to limit the rotatable angle range of the first body 1 relative to the second body 2, so that in the first target state, the rotatable angle range of the first body 1 relative to the second body 2 can be the first angle range, and in the second target state, the rotatable angle range of the first body 1 relative to the second body 2 can be the second angle range, and when the electronic device contacts the supporting object during use, the electronic device can maintain an independent static state with the supporting object.

[0080] In a specific embodiment, the first angle range can be 0 to 135°, and the second angle range can be 0 to 120°. In the first target state, the first body 1 can be opened to the maximum value of 135° in the first angle range, achieving the user experience of a normal laptop; in the second target state, the first body 1 can be opened to the maximum value of 120° in the second angle range, reducing the possibility that the end of the first body 1 away from the hinge mechanism contacts or approaches the desktop or other supporting objects (i.e., topples) under the action of gravity in the second target state. This can not only meet the user's demand for a large screen, but also reduce the possibility of toppling.

[0081] In a specific embodiment, the electronic device may include a first body 1, a second body 2, and a target component; the first body 1 may include a display component, the first body 1 may have a switchable first display state and a second display state, and the display area of ​​the display component in the first display state may be different from the display area of ​​the display component in the second display state; the second body 2 may be rotatably connected to the first body 1; the target component may be used to limit the rotatable angle range of the first body 1 relative to the second body 2, and the target component may have a first target state and a second target state. In the first target state, the rotatable angle range of the first body 1 relative to the second body 2 may be a first angle range, and in the second target state, the rotatable angle range of the first body 1 relative to the second body 2 may be a second angle range, and the second angle range may be different from the first angle range. When the display component is switched to the first display state, the target component is switched to the first target state, and when the display component is switched to the second display state, the target component is switched to the second target state, so that when the electronic device is in different display states, the rotatable angle range of the first body 1 relative to the second body 2 is different. The user can adjust the rotation angle of the first body 1 relative to the second body 2 according to the different display areas of the first body 1, so that when the electronic device presents a variety of display modes, it can have a better viewing angle, improve the user's comfort and convenience of use, and meet the needs of different people. The target component switching state can limit the rotation angle of the first body 1 relative to the second body 2 within a certain range.

The driving member 3 may drive the brake member so that the brake member 30 can switch between the first matching relationship and the second matching relationship with the rotating shaft mechanism.

[0083] The driving member 34 and the braking member 30 are connected by transmission; the driving member 34 is used to drive the braking member 30, so that the position of the braking member 30 changes to limit the opening angle of the first body 1 relative to the second body 2, so that in the first target state, the rotatable angle range of the first body 1 relative to the second body 2 can be a first angle range, and in the second target state, the rotatable angle range of the first body 1 relative to the second body 2 can be a second angle range. The change in the position of the braking member 30 can cause the rotatable angle range of the first body 1 relative to the second body 2 to change between the first angle range and the second angle range. In this embodiment, the driving member 34 drives the braking member 30, so that the position of the braking member 30 can be changed, thereby limiting the rotatable angle range of the first body 1 relative to the second body 2. When the display component switches to the first display state, the target component switches to the first target state, and the rotatable angle range of the first body 1 relative to the second body 2 can be the first angle range. When the display component switches to the second display state, the target component switches to the second target state, and the rotatable 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 rotatable angle ranges of the first body 1 relative to the second body 2 when it is in different display states. This not only allows users to adjust the angle of the first body 1 of the electronic device based on different usage requirements, so that users can find the appropriate usage angle of the first body 1 of the electronic device in different display states, thereby improving the user's experience of using the electronic device; it can also be stably placed on a desktop or other supporting object, that is, when the electronic device contacts the supporting object during use, the electronic device can maintain an independent static state with the supporting object.

When the brake member 30 is separated from the abutment portion 311, the brake member 30 is always not in contact with the abutment portion 311 when the first body 1 rotates relative to the second body 2. In this embodiment, the brake member 30 is driven by the driving member 34, so that the position of the brake member 30 can be changed, thereby switching the target state of the target component. When the display component is switched to the first display state, the brake member 30 is in the second position, the target component is switched to the first target state, and the rotatable angle range of the first body 1 relative to the second body 2 can be the first angle range.When the display component is switched to the second display state, the brake member 30 is in the first position, the target component is switched to the second target state, and the rotatable angle range of the first body 1 relative to the second body 2 can be a second angle range, so that when the electronic device is in different display states, the rotatable angle range of the first body 1 relative to the second body 2 is different, so that it can be stably placed on a desktop or other supporting object, that is, when the electronic device contacts the supporting object during use, the electronic device can maintain an independent static state with the supporting object.

The first rotating member 31 is provided with an abutment portion 311. The electronic device may further include a controller, the controller is used to generate a first control signal or a second control signal; the controller may be connected to a driving member 34, the driving member 34 may be used to drive the brake member 30 to move to the first position according to the first control signal, so that the brake member 30 can abut against the abutment portion 311, so as to limit the rotation angle of the first rotating member 31, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be a second angle; the driving member 34 is used to drive the brake member 30 to move to the second position according to the second control signal, so that the brake member 30 can be separated from the abutment portion 311, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the first angle. Optionally, the first angle can be the maximum value of the first angle range, and the second angle can be the maximum value of the second angle range. The brake member 30 can be coaxially arranged with the first rotating member 31, and the first rotating member 31 is provided with an abutment portion 311. When the controller generates the first control signal, the driving member 34 drives the brake member 30 to move to the first position, the brake member 30 can abut against the abutment portion 311, and the target assembly switches to the second target state, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the second angle. When the controller generates the first control signal, the driving member 34 drives the support member to move to the second position, the brake member 30 can be separated from the abutment portion 311, and the target assembly switches to the first target state, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the first angle. In this embodiment, the controller controls the driving member 34 to drive the brake member 30, so that the position of the brake member 30 can be changed, thereby switching the target state of the target assembly.

When the display assembly switches to the second display state, the brake member 30 is in the first position, the target assembly switches to the second target state, and the rotatable angle range of the first body 1 relative to the second body 2 can be the second angle range.Therefore, when the electronic device is in different display states, the rotatable angle range of the first body 1 relative to the second body 2 is different, so that it can be stably placed on a desktop or other supporting object. That is, when the electronic device contacts the supporting object during use, the electronic device can maintain an independent static state with the supporting object.

[0090] Optionally, when a key operation is performed on the electronic device, a control signal corresponding to the key operation can be generated, and the control signal can be a first control signal, a second control signal, or a third control signal. The driver 34 performs a corresponding control operation according to the control signal. The driver 34 drives the brake member 30 to move to the first position according to the first control signal, so that the brake member 30 can abut against the abutment portion 311 to limit the rotation angle of the first rotating member 31, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the second angle; the driver 34 drives the brake member 30 to move to the second position according to the second control signal, so that the brake member 30 can be separated from the abutment portion 311, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the first angle.

[0091] On the basis of the above, the abutment portion 311 may include an abutment wall 311a. When the controller generates a first control signal, the driving member 34 drives the brake member 30 to move to the first position, and the brake member 30 may abut against the abutment wall 311a. The target assembly switches to the second target state, so that the maximum unfolding angle of the first body 1 relative to the second body 2 can be the second angle. The abutment wall 311a can abut against the brake member 30 when the unfolding angle of the first body 1 relative to the second body 2 is the second angle, so that when the electronic device is in the second display state, the maximum rotatable angle of the first body 1 relative to the second body 2 can be the second angle, so that when the electronic device is opened to the second angle, the second body 2 can be relatively still with the horizontally arranged support. When the second body 2 of the electronic device contacts the support object during use, the possibility of the end of the first body 1 away from the rotating shaft mechanism contacting or approaching the desktop or other support objects (i.e. tipping) under the action of gravity can be reduced, so that the electronic device can be stably placed on the desktop or other support objects.

When the driving member 34 drives the screw rod 38 to rotate, the slider 37 disposed on the screw rod 38 can move along the axial direction of the screw rod 38. When the slider 37 moves in the direction close to the first rotating member 31, the slider 37 can drive the brake member 30 to move the brake member 30 to the first position, so that the brake member 30 can abut against the abutment portion 311, and the target assembly switches to the second target state, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the maximum value of the second angle range. Optionally, the slider 37 and the brake member 30 can be connected by a connecting rod 40. The brake member 30 is separated from the abutment portion 311, and the target assembly can switch to the first target state, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the maximum value of the first angle range. The slider 37 can be slidably matched with the guide column 36, so that the slider 37 can move along the axial direction of the guide column 36, thereby improving the stability of the movement of the slider 37, thereby improving the stability of the brake member 30, and improving the stability of the target assembly switching between the first target state and the second target state.

[0094] On the basis of the above, the brake member 30 forms a limiting portion, which is arranged at one end of the brake member 30 close to the first rotating member 31. The limiting portion can be used to abut against the abutment portion 311 when in the first position, and the limiting portion can be separated from the abutment portion 311 when in the second position. When the driving member 34 drives the brake member 30 to move the brake member 30 to the first position, the limiting portion abuts against the abutment portion 311, and the target component switches to the second target state, so that the maximum expansion angle of the first body 1 relative to the second body 2 can be the maximum value of the second angle range.
