[0096] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0097] In the description of this application, the references to terms such as "one embodiment," "some embodiments," "example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of those different embodiments or examples.

[0098] In the description of this specification, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0099] See Figures 1-26 This application provides an electronic device that may include a first body 110, a second body 120, and a connecting device 200. The first body 110 may have a first display screen 112, and the second body 120 may have a second display screen 122. The second display screen 122 may be different from the first display screen 112; that is, the second display screen 122 and the first display screen 112 may not be the same component. In other words, the electronic device may have at least two independent display screens. The connecting device 200 may include a first axis 361 and a second axis 362, meaning the connecting device 200 may be a dual-axis rotation device. The connecting device 200 can connect the first body 110 and the second body 120, enabling the first body 110 and the second body 120 to rotate relative to each other. The electronic device may include a target state in which the first body 110 is positioned relative to the second body 120 at a target angle, and at least a portion of the projection of the first axis 361 toward the second axis 362 may be located on either the first body 110 or the second body 120.

[0100] The first body 110 and the second body 120 can rotate relative to each other based on the connecting device 200, causing the included angle α between the first body 110 and the second body 120 to change. This allows adjustment of the relative positions of the first body 110 and the second body 120 of the electronic device, ensuring they are in a target state. The included angle α between the first body 110 and the second body 120 can be the angular distance between the first body 110 and the second body 120 in the target state; that is, the target angle can be the angular distance between the first body 110 and the second body 120 in the target state. The target angle can include a smaller value between 0° and α greater than 0° (e.g., α not greater than 30°). In other words, the target state can include a state where the first body 110 and the second body 120 are completely folded (e.g., ...). Figure 1 and Figure 3 (as shown) and a state that is close to being completely folded.

[0101] The projection of the first axis 361 toward the second axis 362 refers to the projection of the first axis 361 along the direction from the first axis 361 to the second axis 362. The projection being at least partially located on the first body 110 or the second body 120 means that, ignoring any occlusion elements that may exist along the projection path, the projection of the first axis 361 overlaps with the first body 110 or the second body 120 to which the first axis 361 is connected. This overlap can be at least a portion of the projection of the first axis 361, that is, it can be a partial or complete portion of the projection of the first axis 361. The following explanation uses the example of the connecting device 200 where the first axis 361 is connected to the first body 110 and the second axis 362 is connected to the second body 120. See [link to documentation]. Figure 3 and Figure 10 When the first body 110 and the second body 120 are in a fully folded or nearly fully folded relative position, the projection of the first axis 361 toward the second axis 362 may overlap with the surface of the first body 110 near the second body 120. See also Figure 5 and Figure 7 As the opening angle of the first body 110 and the second body 120 increases, the overlap between the projection of the first axis 361 toward the second axis 362 and the opened surface of the first body 110 decreases. See also Figure 3 and Figure 24 When the first body 110 and the second body 120 are in a fully folded or nearly fully folded relative position, the projection of the first axis 361 toward the second axis 362 can overlap with the first display screen 112 on the first body 110. See also Figure 25 and Figure 26 As the opening angle of the first body 110 and the second body 120 increases, the overlap between the projection of the first axis 361 toward the second axis 362 and the first display screen 112 decreases.

[0102] When the first body 110 and the second body 120 of the electronic device are in a fully folded relative position, the included angle α between the first body 110 and the second body 120 is equal to or approximately equal to 0°. The opposing surfaces of the first body 110 and the second body 120 satisfy the parallel condition and are located on the mating plane (the mating plane is a virtual plane; during the folding process, the first body 110 and the second body 120 move closer to the mating plane). After the first body 110 and the second body 120 are opened, a seam is formed between the first display screen 112 and the second display screen 122 between their adjacent edges. The width of the seam affects the user's experience of viewing the combined two-screen display. In related technologies, as the first body 110 and the second body 120 are opened, the edges of the first body 110 and the second body 120 that form the seam move away from the mating plane prematurely, resulting in a wider seam. In the electronic device provided in this application, by setting the projection of the first axis 361 toward the second axis 362 in the target state to at least partially be located on the first body 110 or the second body 120, it is possible to ensure that the edge of the seam forming between the first body 110 and the second body 120 moves away from the mating plane only after the first body 110 and the second body 120 have opened a large angle. This results in a narrower seam, which improves the user experience when viewing the dual-screen display. For example, in... Figure 7 and Figure 8 When the display is in the open state, the seam between the first display screen 112 and the second display screen 122 is almost invisible. In this way, when using the two-screen combined mode, that is, when the complete display screen is presented by the first display screen 112 and the second display screen 122, the electronic device can present a seamless display effect, eliminating or reducing the visual disjointed feeling when the two screens are displayed together, thereby effectively improving the user experience.

[0103] It should be noted that the cross-sectional dimensions of the first axis 361 and the second axis 362 can be the same or different. In either case, as long as the projection of the first axis 361 toward the second axis 362 in the target state can be at least partially located on the first body 110 or the second body 120, it will help to make the gap between the first display screen 112 and the second display screen 122 narrower after the first body 110 and the second body 120 are opened, thereby improving the user experience of viewing the screen combined into one.

[0104] See Figures 3-10The first shaft 361 of the connecting device 200 may have a first axis S1. The first shaft 361 may be a shaft component of the connecting device 200 coaxially arranged with the first axis S1 as the axis. It should be noted that the first shaft 361 may include multiple (i.e., two or more) shaft components arranged coaxially. These shaft components of the first shaft 361 may be directly connected or indirectly connected. In addition, the shaft components of the first shaft 361 may be fixedly arranged in the connecting device 200 or rotatably arranged in the connecting device 200. For example, in some embodiments, depending on the different rotational needs of different parts of the first shaft 361 distributed along the axial direction, some shaft components of the first shaft 361 may be fixedly arranged in the connecting device 200, while shaft components of other positions may be rotatably arranged in the connecting device 200. Shaft components at different positions may be indirectly connected through other components of the connecting device 200.

[0105] Similarly, the second shaft 362 of the connecting device 200 may have a second axis S2. The second shaft 362 may be a shaft component of the connecting device 200 coaxially arranged with the second axis S2 as the axis. It should be noted that the second shaft 362 may include multiple (i.e., two or more) shaft components coaxially arranged. These shaft components of the second shaft 362 may be directly connected or indirectly connected. In addition, the shaft components of the second shaft 362 may be fixedly arranged in the connecting device 200 or rotatably arranged in the connecting device 200. For example, in some embodiments, depending on the different rotational needs of different parts of the second shaft 362 distributed along the axial direction, some shaft components of the second shaft 362 may be fixedly arranged in the connecting device 200, while shaft components of other positions may be rotatably arranged in the connecting device 200. Shaft components of different positions may be indirectly connected through other components of the connecting device 200.

[0106] The axes of the first axis 361 and the second axis 362 can define a target plane P. The target plane P can pass through the axis of the first axis 361 and the axis of the second axis 362. That is, the target plane P can be the plane containing the first axis S1 and the second axis S2. The projection of the first axis 361 toward the second axis 362 can refer to the projection of the first axis 361 onto the second axis 362 along the target plane P. In other words, it can refer to the orthographic projection of the first axis 361 toward the second axis 362 along a direction parallel or approximately parallel to the target plane P.

[0107] Electronic devices can be of various types, such as laptops, mobile phones, and monitors; this application does not limit the scope of the application. See also Figure 1 , Figure 2 and Figure 9In some embodiments, the connecting device 200 may include a cover 400 and a rotating mechanism 300. The cover 400 may serve as a carrier for the rotating mechanism 300, meaning the rotating mechanism 300 may be mounted on the cover 400. Multiple rotating mechanisms 300 may be provided on the cover 400. In the axial direction of the first axis 361 and the second axis 362 of the connecting device 200, the cover 400 may be sized similarly to the first body 110 and the second body 120. That is, in the axial direction, the size of the cover 400 may be approximately equal to the size of the first body 110 and the second body 120. Thus, the side of the cover 400 facing away from the rotating mechanism 300 can serve as the exterior surface of the electronic device, making the overall appearance of the electronic device more streamlined.

[0108] In some embodiments, the connecting device 200 may include a target component 350, which may connect to the first axis 361 and the second axis 362. That is, the target component 350 may refer to a component that simultaneously connects the first axis 361 and the second axis 362. The first display screen 112 and the second display screen 122 may be located on a first side of the target plane P defined by the first axis S1 and the second axis S2. The target component 350 may include a first region T located on the first side of the target plane P and a second region N located on a second side of the target plane P, with the second side opposite to the first side. The volume of the target component 350 in the first region T is smaller than the volume of the target component 350 in the second region N. That is, the volume of the target component 350 on the side of the target plane P facing away from the first display screen 112 and the second display screen 122 is larger than the volume on the other side of the target plane P. In other words, the target component 350 occupies more space on the side of the target plane P facing away from the first display screen 112 and the second display screen 122. In this way, the connecting device 200 can provide more space for the end of the first display screen 112 and the second display screen 122 that is close to the connecting device 200, so that the ends of the first display screen 112 and the second display screen 122 that are close to the connecting device 200 can be set closer to each other, making the physical seam between the first display screen 112 and the second display screen 122 narrower and improving the display effect when the two screens are displayed together.

[0109] See Figures 24-26In some embodiments, during the relative rotation of the first body 110 and the connecting device 200, the end of the first display screen 112 near the connecting device 200 can move relative to the connecting device 200 in a direction K perpendicular to the target plane P; during the relative rotation of the second body 120 and the connecting device 200, the end of the second display screen 122 near the connecting device 200 can move relative to the connecting device 200 in a direction K perpendicular to the target plane P. The movement trajectories of the adjacent edges of the first display screen 112 and the second display screen 122 at the connecting device 200 affect the size of the seam between the two display screens. Setting their movement trajectories as straight lines or approximately straight lines perpendicular to the target plane P allows the electronic device to be adjusted to multiple different states while ensuring that the physical seam between the first display screen 112 and the second display screen 122 is as small as expected, avoiding a visual disjointed feeling for the user when the two display screens are combined to display images.

[0110] In some embodiments, the first body 110 and the second body 120 may be configured to rotate synchronously relative to the connecting device 200, that is, during the relative rotation of the first body 110 and the second body 120, both the first body 110 and the second body 120 rotate relative to the connecting device 200. Of course, in other embodiments, the first body 110 and the second body 120 may be configured to rotate asynchronously relative to the connecting device 200, that is, during the relative rotation of the first body 110 and the second body 120, only one of the first body 110 and the second body 120 may rotate relative to the connecting device 200, while the other may remain stationary relative to the connecting device 200.

[0111] See Figures 3-10 , Figures 24-26 In some embodiments, the connecting device 200 may include a third region, which may be symmetrical to the second region N about the target plane P. The difference between the third region and the first region T may be a fourth region M. That is, the fourth region M may be the target space formed by performing a volume difference logic operation on the portion of the target component 350 located on the target plane P away from the first display screen 112 and the second display screen 122, symmetrically moved to the other side of the target plane P, and the portion of the target component 350 located on the target plane P closer to the first display screen 112 and the second display screen 122. Since the fourth region M provides a certain space, it can provide more convenience for the rotation of the first display screen 112 and the second display screen 122 relative to the connecting device 200. In this way, it is easier to set the movement trajectory of the end of the first display screen 112 and the second display screen 122 closer to the connecting device 200 to satisfy the perpendicular condition of the target plane P.

[0112] In some embodiments, the first body 110 may include a first housing 111, and the second body 120 may include a second housing 121. The first housing 111 and the second body 120 may provide a receiving cavity for accommodating at least a portion of the connecting device 200. This not only allows the first display screen 112 and the second display screen 122 to be arranged closer together, but also minimizes the exposed area of ​​the connecting device 200, making the electronic device look cleaner.

[0113] The electronic device may include a first state and a second state. In the first state, the first display screen 112 and the second display screen 122 may face each other, that is, the first display screen 112 and the second display screen 122 face each other. The first display screen 112 and the second display screen 122 may be at least partially located in the fourth region M. The first target region of the connecting device 200 may be located within the first housing 111 and / or the second housing 121. In the second state, the first display screen 112 and the second display screen 122 may face the same direction. The projections of the first display screen 112 and the second display screen 122 onto the connecting device 200 along the direction K that satisfies the perpendicular condition to the target plane P may overlap with the fourth region M. The second target region of the connecting device 200 may be located within the first housing 111 and / or the second housing 121. The surface area of ​​the second target region may be greater than the surface area of ​​the first target region. That is, when the electronic device switches from the first state to the second state, the portion of the connecting device 200 housed within the first housing 111 and / or the second housing 121 increases, and correspondingly, the portion of the connecting device 200 exposed outside the first housing 111 and the second housing 121 decreases.

[0114] It should be noted that the first target area can be the portion of the connecting device 200 located within the first housing 111 in the first state, or the portion of the connecting device 200 located within the second housing 121 in the first state, or the sum of the portions of the connecting device 200 located within the first housing 111 and the portions located within the second housing 121 in the first state. Similarly, the second target area can be the portion of the connecting device 200 located within the first housing 111 in the second state, or the portion of the connecting device 200 located within the second housing 121 in the second state, or the sum of the portions of the connecting device 200 located within the first housing 111 and the portions located within the second housing 121 in the second state. When comparing the surface areas of the second target area and the first target area, the comparison should be based on the same accommodating cavity. For example, if the first target area is the portion of the connecting device 200 located within the first housing 111 in the first state, then when comparing the surface areas, the second target area should refer to the portion of the connecting device 200 located within the first housing 111 in the second state. When the first target area is the portion of the connecting device 200 located within the first housing 111 in the first state plus the portion located within the second housing 121, the second target area should refer to the portion of the connecting device 200 located within the first housing 111 in the second state plus the portion located within the second housing 121 when comparing the size of the surface areas.

[0115] In some embodiments, during the switching between the first state and the second state, the distance between the surface of the first display screen 112 of the first body 110 and the surface of the second display screen 122 of the second body 120 located at the connecting device 200 can satisfy the condition of invariance. That is, during the switching between the first state and the second state, the distance remains unchanged or approximately unchanged. For example, when the distance is 0.8 mm, the change in distance is only 0.02 to 0.05 mm, which is much less than 0.8 mm.

[0116] It is easy to understand that, in order to minimize the visual impact of the seam between the first display screen 112 and the second display screen 122 when displaying an image together, the screen of the display should extend as far as possible to the edge of the surface of the body on which it is located. In some embodiments, the first display screen 112 may be disposed on the first surface of the first body 110, and the second display screen 122 may be disposed on the second surface of the second body 120. The end of the first surface near the connecting device 200 may be the first side, the end of the second surface near the connecting device 200 may be the second side, the end of the first display screen 112 near the connecting device 200 may be the third side, and the end of the second display screen 122 near the connecting device 200 may be the fourth side. The third side may be located on the first side, that is, the third side may be a component of the first side, and the fourth side may be located on the second side, that is, the fourth side may be a component of the second side.

[0117] In some embodiments, the electronic device can be configured such that, during the switching between the first state and the second state, the gap width between the first side and the second side is no greater than a preset value, so that the side of the connecting device 200 closest to the first display screen 112 and the second display screen 122 meets the condition of not being exposed. This way, the user will not be visually disturbed by the connecting device 200 when viewing the electronic device's display screen, which is beneficial for improving the display effect when the first display screen 112 and the second display screen 122 display the same image. It should be noted that the condition of not being exposed on the side of the connecting device 200 closest to the first display screen 112 and the second display screen 122 means that this side of the connecting device 200 is obscured by the first body 110 and the second body 120 to the point that it is visually negligible. It is easy to understand that the aforementioned preset value should be a small value, such as 0.8 mm, 0.5 mm, etc.

[0118] See Figures 3-8 , Figures 24-26 In the first body 110 and the second body 120 of the electronic device, there are Figure 3 The status shown is turned on. Figure 7 In the process shown, or vice versa, by Figure 7 The state shown is closed to Figure 3 During the process shown, the width of the gap between the first display screen 112 and the second display screen 122 can remain constant.

[0119] In some embodiments, in a first state, the first body 110 and the second body 120 can be stacked; in a second state, the first body 110 and the second body 120 can be flattened, and the first display screen 112 and the second display screen 122 can satisfy the coplanar condition. See also Figures 3-8 The stacking of the first body 110 and the second body 120 can mean that the included angle α becomes 0° or approximately 0°, and the flattening of the first body 110 and the second body 120 can mean that the included angle α becomes 180° or approximately 180°. When the first body 110 and the second body 120 are flattened, the first display screen 112 and the second display screen 122 meet the coplanar condition, which can form a flat display surface for the two screens combined into one, thereby making the overall picture of the two screens combined into one stronger and improving the user's viewing experience.

[0120] See Figure 7 and Figure 30In some embodiments, the electronic device may include at least a dustproof component for shielding against dust. The dustproof component may include a first shield 113 and / or a second shield 123. The first shield 113 may be connected to the end of the first body 110 near the connecting device 200 and protrude from the edge of the first body 110. The second shield 123 may be connected to the end of the second body 120 near the connecting device 200 and protrude from the edge of the second body 120. In the second state, the dustproof component can shield the gap between the first display screen 112 and the second display screen 122, preventing impurities such as dust and fine sand from entering the interior of the connecting device 200 through the gap. This helps to avoid negative impacts such as increased resistance and friction damage to the normal movement of the moving parts of the connecting device 200 caused by dust and other impurities.

[0121] Before folding the electronic device, i.e., before switching from the second state to the first state, the user can first turn the electronic device in the second state upside down and gently shake it up and down to empty any impurities covered by the dust cover from the gap between the first display screen 112 and the second display screen 122, and then fold the electronic device. Of course, even if the user does not empty the impurities covered by the dust cover before folding the electronic device, as the first body 110 and the second body 120 rotate relative to each other, the impurities will fall into a specific small area under the guidance of the dust cover. That is, the dust cover also has the function of guiding the impurities to a designated area during the relative rotation of the first body 110 and the second body 120. Under the guidance of the dust cover, the impurities are confined to a very limited area within the connecting device 200, which can effectively prevent impurities from running around inside the connecting device 200 and reduce the risk of impurities causing negative impacts such as increased resistance and friction damage to the normal movement of the moving parts of the connecting device 200.

[0122] Dustproof components can be made of types such as brushes or thin, soft sheets. Figure 30 In the exemplary embodiment shown, the dustproof component may include a first shielding member 113 and a second shielding member 123, that is, in the second state, the first shielding member 113 and the second shielding member 123 together shield the gap between the first display screen 112 and the second display screen 122. In other embodiments, the dustproof component may also be composed of one of the first shielding member 113 and the second shielding member 123, that is, the dustproof component may only have the first shielding member 113 or the second shielding member 123. Taking the dustproof component only having the first shielding member 113 as an example, the portion of the first shielding member 113 protruding from the edge of the first body 110 can completely shield the gap between the first display screen 112 and the second display screen 122, so it is not necessary to have the second shielding member 123.

[0123] In some embodiments, the target member 350 may have a first portion connected to a first axis 361, a second portion connected to a second axis 362, and a third portion connecting the first portion and the second portion. The target member 350 may be configured such that the entire third portion is located on the second side of the target plane P, thereby forming a fourth region M between the first portion and the second portion. Alternatively, the target member 350 may be configured such that the third portion is divided by the target plane P into a first portion located on the first side and a second portion located on the second side, the first portion being smaller than the second portion, thereby forming a fourth region M between the first portion and the second portion. That is, the target member 350 may have various structural forms to choose from in order to form the fourth region M between the first portion and the second portion.

[0124] In some embodiments, the electronic device may have a third state and a fourth state. In the third state, the relative angle between the first body 110 and the second body 120 may be a first angle, and the volume of the first display screen 112 and / or the second display screen 122 located in the fourth region M may be a first value. In the fourth state, the relative angle between the first body 110 and the second body 120 may be a second angle, which may be greater than the first angle, and the volume of the first display screen 112 and / or the second display screen 122 located in the fourth region M may be a second value, which may be less than the first value. The relative angle between the first body 110 and the second body 120 may refer to the angle α between the plane of the first display screen 112 of the first body 110 and the plane of the second display screen 122 of the second body 120. As the first body 110 and the second body 120 rotate relative to each other, the relative angle between the first body 110 and the second body 120 may change, and at the same time, the volume of the fourth region M occupied by the first display screen 112 and / or the second display screen 122 may change. When the electronic device switches from the third state to the fourth state, the relative angle between the first body 110 and the second body 120 increases, and the volume of the fourth region M occupied by the first display screen 112 and / or the second display screen 122 decreases. Conversely, when the electronic device switches from the fourth state to the third state, the relative angle between the first body 110 and the second body 120 decreases, and the volume of the fourth region M occupied by the first display screen 112 and / or the second display screen 122 increases.

[0125] It should be noted that the aforementioned first value can be the volume of the first display screen 112 located in the fourth region M in the third state, or the volume of the second display screen 122 located in the fourth region M in the third state, or the sum of the volumes of the first display screen 112 and the second display screen 122 in the fourth region M in the third state. Similarly, the aforementioned second value can be the volume of the first display screen 112 located in the fourth region M in the fourth state, or the volume of the second display screen 122 located in the fourth region M in the fourth state, or the sum of the volumes of the first display screen 112 and the second display screen 122 in the fourth region M in the fourth state. When comparing the magnitudes of the first and second values, the comparison should be based on the same display screen configuration. For example, if the first value is the volume of the first display screen 112 located in the fourth region M in the third state, then when comparing the magnitudes of the first and second values, the second value should refer to the volume of the first display screen 112 located in the fourth region M in the fourth state. When the first value is the volume of the first display screen 112 in the third state located in the fourth region M plus the volume of the second display screen 122 in the third state located in the fourth region M, when comparing the size of the first value and the second value, the second value should refer to the volume of the first display screen 112 in the fourth state located in the fourth region M plus the volume of the second display screen 122 in the fourth state located in the fourth region M.

[0126] In some embodiments, in the first state, the relative angle between the first body 110 and the second body 120 can be a third angle, which can be smaller than the first angle. The volume of the first display screen 112 and / or the second display screen 122 located in the fourth region M can be a third value, which can be greater than the first value. It should be noted that the aforementioned third value can be the volume of the first display screen 112 located in the fourth region M in the first state, or the volume of the second display screen 122 located in the fourth region M in the first state, or the sum of the volumes of the first display screen 112 and the second display screen 122 located in the fourth region M in the first state. When comparing the magnitudes of the aforementioned first and second values, the comparison should be based on the same display screen configuration.

[0127] See Figure 27 and Figure 28In some embodiments, the electronic device may include a fifth state in which the first display screen 112 and the second display screen 122 may face the same direction, and their projections along a direction K perpendicular to the target plane P may overlap. During relative rotation of the first body 110 and the connecting device 200, the second body 120 may remain stationary relative to the connecting device 200, and the end of the first display screen 112 near the connecting device 200 may move relative to the connecting device 200 in a first active area. During relative rotation of the second body 120 and the connecting device 200, the first body 110 may remain stationary relative to the connecting device 200, and the end of the second display screen 122 near the connecting device 200 may move relative to the connecting device 200 in a second active area, where the second active area and the first active area may overlap. That is, the first body 110 and the second body 120 can rotate asynchronously relative to the connecting device 200. During the relative rotation of the first body 110 and the second body 120, only one of the first body 110 and the second body 120 can rotate relative to the connecting device 200, while the other can remain stationary relative to the connecting device 200. The first body 110 may have a first overlapping portion 101, and the second body 120 may have a second overlapping portion 102. When the first body 110 and the second body 120 are rotated open to 180° or approximately 180°, the first display screen 112 and the second display screen 122 can face the same direction. The first overlapping portion 101 and the second overlapping portion 102 are stacked in a direction K that satisfies the perpendicular condition to the target plane P. Figure 27 or Figure 28 In the exemplary embodiment, the first overlapping portion 101 is stacked on the side of the second overlapping portion 102 facing away from the target plane P. When it is necessary to fold the electronic device, the second body 120 can be rotated first, and the end of the second display screen 122 near the connecting device 200 (i.e., the end where the second overlapping portion 102 is located) can move along the first curved trajectory R1 in the fourth region M (the second display screen 122 performs a non-centering rotation relative to the cover 400). Then the first body 110 is rotated, and the end of the first display screen 112 near the connecting device 200 (i.e., the end where the first overlapping portion 101 is located) can move along the second curved trajectory R2 in the fourth region M (the first display screen 112 performs a non-centering rotation relative to the cover 400). The second curved trajectory R2 and the first curved trajectory R1 have an overlapping portion, that is, in the movement plane of the first display screen 112 and the second display screen 122, the first curved trajectory R1 and the second curved trajectory R2 have an intersection point.

[0128] Of course, in other embodiments, it can also be configured such that, in the fifth state, the second overlapping portion 102 is stacked on the side of the first overlapping portion 101 facing away from the target plane P. When it is necessary to fold the electronic device, the first body 110 can be rotated first, and then the second body 120 can be rotated. See also Figure 27 In some embodiments, in the fifth state, the first display screen 112 and the second display screen 122 can satisfy the coplanar condition. Of course, in other embodiments, the fifth state can also be configured as follows: Figure 28 As shown, in the fifth state, the first display screen 112 and the second display screen 122 may not satisfy the coplanar condition.

[0129] It should be noted that, in Figure 27 or Figure 28 In the exemplary embodiment, in the fifth state, the projections of the first display screen 112 and the second display screen 122 along the direction K that satisfies the perpendicular condition to the target plane P may have an overlapping portion, while the projections of the first housing 111 of the first body 110 and the second housing 121 of the second body 120 along this direction may not have an overlapping portion. That is, in the fifth state, the shapes of the first housing 111 and the second housing 121 may be similar to... Figure 7 The presentation is the same.

[0130] See Figures 9-23 In some embodiments, the connecting device 200 may include a first swing member 321 and a second swing member 322. The first swing member 321 may connect the first shaft 361 and the first body 110, and the second swing member 322 may connect the second shaft 362 and the second body 120. The target member 350 may include a slider 323 slidably connected to the first shaft 361 and the second shaft 362, i.e., the slider 323 may be configured as one of the target members 350. During the relative rotation of the first swing member 321 and the second swing member 322, the first swing member 321 may push the slider 323 to slide along the first shaft 361 through two first contact portions 321a distributed circumferentially along the first shaft 361, and the second swing member 322 may push the slider 323 to slide along the second shaft 362 through two second contact portions 322a distributed circumferentially along the second shaft 362.

[0131] The first swing member 321, the second swing member 322, and the sliding member 323 can constitute a synchronous rotation assembly. This assembly controls the synchronous rotation of the first body 110 and the second body 120, which are rotatably connected via the connecting device 200, relative to the connecting device 200. In related technologies, synchronous rotation assemblies suffer from poor stability and reliability, often resulting in noticeable rotational jamming after a period of use, negatively impacting the user experience. In the embodiments provided in this application, the first swing member 321 may have two first contact portions 321a distributed circumferentially along the first axis 361 for pushing the slider 323 to slide along the first axis 361, and the second swing member 322 may have two first contact portions 321a distributed circumferentially along the second axis 362 for pushing the slider 323 to slide along the second axis 362. In this way, the slider 323 is subjected to more uniform force during the rotation provided by the connecting device 200, and is less prone to deformation and damage. Therefore, the synchronous rotation assembly can be made more stable in quality during service, and the stability and reliability of the synchronous rotation of the first body 110 and the second body 120 connected by the connecting device 200 can be improved, which is beneficial to improving the user experience.

[0132] It should be noted that the aforementioned embodiment in which the first body 110 and the second body 120 can rotate asynchronously relative to the connecting device 200 can be achieved by omitting the first swing member 321, the second swing member 322 and the sliding member 323. That is, without the synchronous rotation component, since there is no synchronous rotation constraint, the first body 110 and the second body 120 can rotate asynchronously relative to the connecting device 200.

[0133] In some embodiments, the slider 323 may include a first connecting portion 301 connected to a first shaft 361 and a second connecting portion 302 connected to a second shaft 362. Both ends of the first connecting portion 301 and / or the second connecting portion 302 along the rotation axis of the connecting device 200 may be provided with protrusions 304 distributed circumferentially along the shaft to which the connecting portion is connected. The protrusions 304 are used to connect with the first contact portion 321a or the second contact portion 322a. It is readily understood that since the first swing member 321 can push the slider 323 to slide along the first shaft 361 through the two first contact portions 321a distributed circumferentially along the first shaft 361, one or both ends of the first connecting portion 301 may be provided with two protrusions 304 connected to the first contact portions 321a. For example, if protrusions 304 are provided at both ends of the first connecting portion 301, each end of the first connecting portion 301 may have two protrusions 304 distributed circumferentially along the first shaft 361. Similarly, since the second swing member 322 can push the slider 323 to slide along the second axis 362 through the two second contact portions 322a distributed circumferentially along the second axis 362, one or both ends of the second connecting portion 302 can be provided with two protrusions 304 connected to the second contact portions 322a. For example, if both ends of the second connecting portion 302 are provided with protrusions 304, each end of the second connecting portion 302 can be provided with two protrusions 304 distributed circumferentially along the second axis 362.

[0134] The slider 323 may include a third connecting portion 303 connecting the first connecting portion 301 and the second connecting portion 302. Since the slider 323 can be configured as one of the target components 350, the structure of the third connecting portion 303 can be configured with reference to the previous description of the third part of the target component 350, which will not be repeated here. In some embodiments, the slider 323 may be configured such that: the first connecting portion 301 is slidably sleeved on the first shaft 361, the second connecting portion 302 is slidably sleeved on the second shaft 362, the first connecting portion 301 and the second connecting portion 302 are symmetrically provided with a first helical surface, the first helical surface is located on the protrusion 304, and both the first contact portion 321a and the second contact portion 322a are provided with a second helical surface that slides in cooperation with the first helical surface. A helical surface refers to a curved surface extending along a helical line, see [reference]. Figures 16-19 At the same end of the first connecting portion 301 and the second connecting portion 302, the first helical surface 301a and the first helical surface 302a are symmetrically arranged; at the other end of the first connecting portion 301 and the second connecting portion 302, the first helical surface 301b and the first helical surface 302b are symmetrically arranged. Since the structures of the first contact portion 321a and the second contact portion 322a are symmetrically arranged, only one of them will be described as an example. Figure 19As shown, the second contact portion 322a can be cylindrical, surrounded by a first spiral sub-body and a second spiral sub-body arranged in a double spiral structure. The first spiral sub-body and the second spiral sub-body satisfy the condition of being interconnected end to end. That is, one end of the second contact portion 322a defines the first spiral sub-body and the second spiral sub-body's head end, and the other end of the second contact portion 322a defines the first spiral sub-body and the second spiral sub-body's tail end. Both the first spiral sub-body and the second spiral sub-body extend from the head end along a spiral line to the tail end. At the same time, the tail end of the first spiral sub-body and the head end of the second spiral sub-body are connected, forming a double spiral structure with interconnected head to tail.

[0135] In some embodiments, the first oscillating member 321 may be circumferentially fixedly connected to the first shaft 361. For example, the first oscillating member 321 may be provided with a non-circular hole sleeved at a corresponding position on the first shaft 361, and the shaft-like component at that position on the first shaft 361 may be rotatably disposed in the connecting device 200. Of course, in other embodiments, the first oscillating member 321 may be configured to rotate relative to the first shaft 361. For example, the first oscillating member 321 may be provided with a circular hole sleeved at a corresponding position on the first shaft 361, and the shaft-like component at that position on the first shaft 361 may be fixedly disposed in the connecting device 200. Similarly, the second oscillating member 322 and the second shaft 362 may be relatively fixedly disposed or rotatably connected.

[0136] See Figures 14-19 In some embodiments, the connecting device 200 may include a first elastic element 324, which may be connected to the sliding element 323. The elastic restoring force of the first elastic element 324 may be used to make the first helical surface on the sliding element 323 in close contact with the second helical surface on the first contact portion 321a and the second contact portion 322a. This can reduce the possibility of jerky movement due to poor contact between the first swinging element 321 or the second swinging element 322 and the sliding element 323, and make the rotation provided by the connecting device 200 smoother.

[0137] See Figures 9-13 , Figures 20-22In some embodiments, the connecting device 200 may include a rotation control component, which may be used at least to control the movement trajectory of the first body 110 and the second body 120 connected by the connecting device 200. The rotation control component may include a third swing member 331, a fourth swing member 332, and a base 333. The base 333 may be configured as one of the target members 350. One end of the third swing member 331 may have a first sliding connection portion 331a that slides with a first arcuate guide rail 333a disposed on the base 333, and the other end may be rotatably connected to one of the first body 110 and the second body 120. One end of the fourth swing member 332 may have a second sliding connection portion 332a that slides with a second arcuate guide rail 333b disposed on the base 333, and the other end may be rotatably connected to the other of the first body 110 and the second body 120. The base 333 can be fixedly installed in the connecting device 200. The third swing member 331 can rotate relative to the base 333 around the center of the first arc-shaped guide rail 333a. The fourth swing member 332 can rotate relative to the base 333 around the center of the second arc-shaped guide rail 333b.

[0138] The connecting device 200 may include a first connecting member 311 and a second connecting member 312. The first connecting member 311 may be fixedly connected to the first body 110 and hinged to the end of the third swing member 331 away from the first sliding connection portion 331a, thereby achieving a rotational connection between the third swing member 331 and the first body 110. The second connecting member 312 may be fixedly connected to the second body 120 and hinged to the end of the fourth swing member 332 away from the second sliding connection portion 332a, thereby achieving a rotational connection between the fourth swing member 332 and the second body 120. The first connecting member 311 may be slidably connected to the end of the first swing member 321 away from the first shaft 361, thereby achieving a slidable connection between the first swing member 321 and the first body 110. The second connecting member 312 may be slidably connected to the end of the second swing member 322 away from the second shaft 362, thereby achieving a slidable connection between the second swing member 322 and the second body 120.

[0139] The first connecting member 311 can slide relative to the first swing member 321 while rotating with the first swing member 321 around the first axis S1. The first connecting member 311 can also slide relative to the second swing member 322 while rotating with the second swing member 322 around the center of the first arc-shaped guide rail 333a. This allows for constraint and control of the movement trajectory of the first body 110 relative to the connecting device 200. Similarly, the second connecting member 312 can slide relative to the second swing member 322 while rotating with the second swing member 322 around the second axis S2. The second connecting member 312 can also slide relative to the second swing member 322 while rotating with the second swing member 322 around the center of the second arc-shaped guide rail 333b. This allows for constraint and control of the movement trajectory of the second body 120 relative to the connecting device 200.

[0140] In some embodiments, the connecting device 200 may include a torque assembly, which may include: a first torque member 341, one end of which wraps around the first shaft 361 circumferentially to generate rotational torque; and / or a second torque member 342, one end of which wraps around the second shaft 362 circumferentially to generate rotational torque. That is, the torque assembly may only have the first torque member 341, or only have the second torque member 342, or both the first torque member 341 and the second torque member 342 may be provided.

[0141] See Figures 9-13 , Figure 23 The principle by which the first torque member 341 and the second torque member 342 generate rotational torque is the same. The following description uses the second torque member 342 as an example. One end of the second torque member 342 can be provided with a wrapping portion 342a, and the other end can be provided with a third sliding connection portion 342b. The third sliding connection portion 342b can be slidably connected to the second connecting member 312, so that the second body 120 can drive the second torque member 342 to rotate around the second axis S2. The wrapping portion 342a of the second torque member 342 can circumferentially wrap around the corresponding position of the second shaft 362. The shaft component at this position of the second shaft 362 is fixedly disposed in the connecting device 200. During the rotation of the second torque member 342 around the second axis S2, the wrapping portion 342a of the second torque member 342 rubs against the second shaft 362, generating a rotational torque that opposes rotation through friction. It is easy to understand that rotational torque can also be generated when there is a relative rotational tendency between the second torque member 342 and the second shaft 362. In some embodiments, the rotational torque provided by the torque component under rotational tendency can keep the first body 110 and the second body 120 relatively stationary. For example, the first body 110 and the second body 120 can be opened to about 120°, and the user can place the electronic device on a support such as a desktop and use the electronic device in the mode of a regular laptop.

[0142] See Figures 9-15 In some embodiments, the connecting device 200 may include a self-locking component, which may include a first latching member 371, a second latching member 372, and a second elastic member 373 connected to the second latching member 372. The first latching member 371 may be configured as one of the target members 350. The second latching member 372 may be circumferentially rotatably disposed on the first axis 361 or the second axis 362, that is, the second latching member 372 may rotate with the first axis 361 or the second axis 362 where it is located. The elastic restoring force of the second elastic member 373 may be used to make the second latching member 372 and the first latching member 371 in close contact. When the first latching member 371 and the second latching member 372 are latched, the self-locking component may provide a locking force for locking the first body 110 and the second body 120 connected by the connecting device 200.

[0143] like Figure 15 As shown, taking the second latching member 372 mounted on the second shaft 362 as an example, since the first latching member 371 is configured as one of the target members 350, that is, the first latching member 371 is connected to both the first shaft 361 and the second shaft 362, the first latching member 371 can remain stationary while the second shaft 362 rotates with the second latching member 372. Therefore, the second latching member 372 rotates relative to the first latching member 371 under the drive of the second shaft 362. The first latching member 371 and the second latching member 372 are provided with mutually cooperating slots and protrusions. When the second latching member 372 rotates to the position where the slot and the protrusion meet, the second latching member 372 moves along the axial direction of the second shaft 362 under the action of the elastic restoring force of the second elastic member 373, thereby causing the protrusion to engage in the slot to form a latching connection. The latching connection between the first latching member 371 and the second latching member 372 can provide a locking force for locking the first body 110 and the second body 120.

[0144] The locking force provided by the self-locking component allows the first body 110 and the second body 120 to remain more securely stationary at the expected relative angle. For example, in some embodiments, the first latch 371 and the second latch 372 can be configured to latch onto each other when the first body 110 and the second body 120 are opened to 180° or approximately 180°, allowing the user to better use the electronic device in tablet mode. Furthermore, the first latch 371 and the second latch 372 can also be configured to latch onto each other when the first body 110 and the second body 120 are closed to 0° or approximately 0°, thus reducing the possibility of the first body 110 and the second body 120 accidentally coming loose after the electronic device is stored away.

[0145] See Figures 1-28This application also provides a connecting device 200, which may include a first axis 361 and a second axis 362. The connecting device 200 can be used to connect a first body 110 and a second body 120 of an electronic device, so that the first body 110 and the second body 120 can rotate relative to each other, so that the electronic device includes a target state. In the target state, the first body 110 can be at a target angle relative to the second body 120, and the projection of the first axis 361 toward the second axis 362 can be at least partially located on the first body 110 or the second body 120.

[0146] The connecting device 200 can be used to connect the first body 110 and the second body 120 of various types of electronic devices such as laptops, mobile phones, and monitors. The structural form and working principle of the connecting device 200 can be referred to the description of the relevant parts of the connecting device 200 when introducing electronic devices, which will not be repeated here.
