DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] In the description of this specification, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
[0051] See also Figure 1 to Figure 7 The embodiment of the present application provides an electronic device, including a first body 100, a second body 200 and a flexible display screen 300, wherein the first body 100 has a first sub-body 110 and a second sub-body 120 that are slidably connected, the second body 200 is rotationally connected and slidably connected to the first sub-body 110, and can rotate around a target axis P relative to the first sub-body 110, and the relative sliding direction of the first sub-body 110 and the second sub-body 120 and the relative sliding direction of the first sub-body 110 and the second body 200 are both parallel to the target axis P. The flexible display screen 300 has a first portion disposed on the first sub-body 110 and a second portion disposed on the second sub-body 120, and the target display area of the flexible display screen 300 changes size based on the relative sliding of the first sub-body 110 and the second sub-body 120.
[0052] The flexible display screen 300 of the electronic device is arranged on the first body 100. The target display area of the flexible display screen 300 can be understood as the area that displays the screen content to the user when the user uses the electronic device normally. The first part of the flexible display screen 300 is arranged on the first sub-body 110 of the first body 100, and the second part of the flexible display screen 300 is arranged on the second sub-body 120 of the first body 100. The size of the target display area can be adjusted by the relative sliding of the first sub-body 110 and the second sub-body 120. The rotational connection and sliding connection between the second body 200 and the first sub-body 110 means that the second body 200 and the first sub-body 110 can both rotate relative to each other and slide relative to each other. The electronic device can be of various different types such as a laptop computer, a desktop computer, an all-in-one computer, etc., so the second body 200 has a variety of setting methods to choose from. For example, in Figure 1In the exemplary embodiment, the second body 200 can be set as the host of the electronic device, that is, the second body 200 is configured with a computing module for data processing; for example, in other embodiments, the second body 200 can be set as a support, that is, the second body 200 only serves as a structural support member 230 to support the first body 100 (such as a desktop display, or the main body of an all-in-one computer).
[0053] Satisfying the parallel condition means being parallel or approximately parallel, and the relative sliding direction of the first sub-body 110 and the second sub-body 120 and the relative sliding direction of the first sub-body 110 and the second body 200 both satisfy the parallel condition with the target axis P, therefore, the relative sliding direction of the first sub-body 110 and the second sub-body 120 and the relative sliding direction of the first sub-body 110 and the second body 200 satisfy the parallel condition. In order to facilitate understanding of the working principle of the electronic device adjusting the use form, the accompanying drawings of the specification take a laptop as an example to embody the electronic device of the present application, when in use, the second body 200 can be placed on a support such as a desktop, and since the second body 200 and the first sub-body 110 can rotate relative to each other, the first body 100 and the second body 200 can realize opening and closing movements around the target axis P, so that the angle of the flexible display screen 300 toward the user can be adjusted, that is, the first body 100 can perform a pitching movement, so that the angle between the target display area of the flexible display screen 300 and the horizontal plane changes in size. At the same time, since the second body 200 and the first sub-body 110 can slide relative to each other, the first body 100 can move in a direction that satisfies the parallel condition with the target axis P, that is, the first body 100 can move left and right, so that the relative position relationship between the target display area of the flexible display screen 300 and the user changes. Moreover, the first sub-body 110 and the second sub-body 120, which are components of the first body 100, can slide relative to each other to adjust the size of the target display area of the flexible display screen 300, that is, the screen area can be adjusted. When a user uses an electronic device, the use form of the electronic device can be changed by any combination of the above-mentioned adjustment functions, so a very rich use form can be obtained. It can be seen that the electronic device of the present application can well meet the diverse use needs of users.
[0054] In some embodiments, the electronic device may be configured to have at least one of the following first to fourth usage forms: First usage form: The first end of the first body 100 protrudes from the second body 200 along a first direction S1 that satisfies the parallel condition with the target axis P, and the second end of the first body 100 opposite to the first end protrudes from the second body 200 along a second direction S2 opposite to the first direction S1. Second usage state: The first end of the first body 100 protrudes from the second body 200 along the first direction S1, and the second end of the first body 100 is aligned with an end of the second body 200 corresponding to the second end. Third usage state: The second end of the first body 100 protrudes from the second body 200 along the second direction S2, and the first end of the first body 100 is aligned with an end of the second body 200 corresponding to the first end. Fourth usage state: The first end of the first body 100 is aligned with an end of the second body 200 corresponding to the first end, and the second end of the first body 100 is aligned with an end of the second body 200 corresponding to the second end.
[0055] See also Figure 1 In the fourth use form of the electronic device, both ends of the first body 100 and the second body 200 along the target axis P are aligned, and the electronic device as a whole presents a relatively regular shape. Figure 2 In the first use form of the electronic device, both ends of the first body 100 along the target axis P direction protrude from the second body 200, and the electronic device as a whole presents a T-shape, presenting a larger screen area than the fourth use form. It should be noted that in the first use form, the protruding lengths of the two ends of the first body 100 relative to the second body 200 can be the same or different. Figure 3 and Figure 4 In the second and third usage states of the electronic device, only one end of the first body 100 protrudes from the second body 200, and the other end is flush with the corresponding end of the second body 200. The electronic device as a whole presents an inverted L shape, presenting a larger screen area than the fourth usage state, but smaller than the screen area presented in the first usage state.
[0056] In some embodiments, the electronic device may be configured to have a fifth use state: at least one of the first end and the second end of the first body 100 is retracted into the second body 200 along a direction that satisfies the parallel condition with the target axis P. That is, at least one of the first end and the second end of the first body 100 is retracted into the inner side of the corresponding end of the second body 200 relative to the corresponding end of the second body 200. For example, both ends of the first body 100 along the direction of the target axis P are retracted into the second body 200, and the electronic device as a whole presents an inverted T shape. For another example, only one end of the two ends of the first body 100 is retracted into the second body 200, and the other end is flush with or protrudes from the corresponding end of the second body 200, and the electronic device as a whole presents an L shape or a Z shape. It should be noted that, in the case where both ends of the first body 100 are retracted into the second body 200, the retracted lengths of the two ends of the first body 100 relative to the second body 200 may be the same or different.
[0057] In some embodiments, the electronic device may include: a first driving device for driving the first sub-body 110 and the second sub-body 120 to slide relative to each other; a second driving device for driving the first sub-body 110 and the second main body 200 to slide relative to each other; and a controller electrically connected to the first driving device and the second driving device, the controller at least being used to control the first driving device and the second driving device to act simultaneously, and the first sliding speed between the first sub-body 110 and the second sub-body 120 and the second sliding speed between the first sub-body 110 and the second main body 200 satisfy an inverse two-fold relationship. After receiving the request signal containing the user's adjustment intention information, the controller may control the first driving device and the second driving device to act simultaneously, so that the sliding between the first sub-body 110 and the second main body 200 and the sliding between the first sub-body 110 and the second sub-body 120 are performed simultaneously, that is, the first main body 100 changes its position while adjusting the size of the screen area. It should be noted that the first sliding speed refers to the moving speed of the second sub-body 120 with the first sub-body 110 as a reference, and the second sliding speed refers to the moving speed of the first sub-body 110 with the second body 200 as a reference. Satisfying the reverse two-fold relationship means that the speed directions are opposite and the first sliding speed is twice the second sliding speed. That is, in a certain process of changing the size of the target display area, the first sub-body 110 and the second body 200 slide relative to each other, and the direction in which the first sub-body 110 slides relative to the second body 200 is opposite to the direction in which the second sub-body 120 slides relative to the first sub-body 110, and the speed of the second sub-body 120 relative to the first sub-body 110 is twice the speed of the first sub-body 110 relative to the second body 200. For example, in a process where Figure 1 The fourth use state shown is Figure 2In the process of the first use state transition shown, the first sub-body 110 moves relative to the second body 200 at a speed V along the second direction S2, and the second sub-body 120 moves relative to the first sub-body 110 at a speed 2V along the first direction S1. In this way, in a coordinate system with the second body 200 as a reference, both ends of the first body 100 move outward at the same expansion speed V, so that both ends of the first body 100 maintain symmetric positions relative to the second body 200 at any time during the process of adjusting the use state. It is easy to understand that in the reverse process, that is, by Figure 2 The first use state shown is Figure 1 During the transition to the fourth use state shown, the first sliding speed and the second sliding speed satisfying the inverse two-fold relationship also enable both ends of the first body 100 to maintain symmetrical positions relative to the second body 200 at any time during the above process.
[0058] In some embodiments, the controller can be configured to at least control the first driving device and the second driving device to act simultaneously, and the first sliding speed between the first sub-body 110 and the second sub-body 120 and the second sliding speed between the first sub-body 110 and the second body 200 satisfy an inverse equal relationship. That is, in a certain process of changing the size of the target display area, the first sub-body 110 and the second body 200 slide relative to each other, the direction in which the first sub-body 110 slides relative to the second body 200 is opposite to the direction in which the second sub-body 120 slides relative to the first sub-body 110, and the speed of the second sub-body 120 relative to the first sub-body 110 is equal to the speed of the first sub-body 110 relative to the second body 200. For example, in a process of changing the size of the target display area, the first sub-body 110 and the second body 200 slide relative to each other, and the direction in which the first sub-body 110 slides relative to the second body 200 is opposite to the direction in which the second sub-body 120 slides relative to the first sub-body 110. Figure 1 The fourth use state shown is Figure 4 In the process of the third use state transition shown, the first sub-body 110 moves relative to the second body 200 at a speed V along the second direction S2, and the second sub-body 120 moves relative to the first sub-body 110 at a speed V along the first direction S1. In this way, in a coordinate system with the second body 200 as a reference, the end of the first body 100 facing the second direction S2 (i.e., the right end in the figure) moves outward at an expansion speed V, while the end of the first body 100 facing the first direction S1 (i.e., the left end in the figure) remains relatively motionless with the second body 200, so that this end of the first body 100 remains aligned with the corresponding end of the second body 200 at any time during the process of adjusting the use form. It is easy to understand that in the reverse process, i.e., by Figure 4 The third use state shown is Figure 1 During the transition to the fourth use state shown, the first sliding speed and the second sliding speed that satisfy the reverse equality relationship also ensure that the end of the first body 100 facing the first direction S1 remains aligned with the corresponding end of the second body 200 at any time during the above process.
[0059] In some embodiments, the controller may be configured to at least control the first driving device and the second driving device to act separately, that is, in a certain process of adjusting the use form, the sliding between the first sub-body 110 and the second body 200 and the sliding between the first sub-body 110 and the second sub-body 120 are not performed at the same time. Figure 1 The fourth use state shown is Figure 3 During the transition to the second use state shown, the first sub-body 110 remains relatively stationary relative to the second body 200, and the second sub-body 120 moves relative to the first sub-body 110 along the first direction S1 at a speed V, so that the end of the first body 100 facing the first direction S1 (i.e., the left end in the figure) moves outward at an expansion speed V, while the end of the first body 100 facing the second direction S2 (i.e., the right end in the figure) is always aligned with the corresponding end of the second body 200. Figure 2 The first use state shown is Figure 3 During the transition to the second use state shown in FIG. 1 , the second sub-body 120 remains relatively stationary relative to the first sub-body 110, and the first sub-body 110 moves relative to the second body 200 along the first direction S1 at a speed V. Figure 2 The first use state shown is Figure 4 During the transition to the third use state, the second sub-body 120 remains relatively stationary relative to the first sub-body 110 , and the first sub-body 110 moves at a speed V along the second direction S2 relative to the second body 200 .
[0060] In some embodiments, the flexible display screen 300 can be configured to achieve expansion and contraction of the target display area only at one end of the first sub-body 110 in a direction that satisfies the condition of being parallel to the target axis P. Figure 1~Figure 4 In the exemplary embodiment, the flexible display screen 300 realizes screen expansion and reduction only at the end of the first sub-body 110 facing the first direction S1. In this way, some structures such as interfaces, heat dissipation holes, sound outlet holes, etc. can be set at the end of the first sub-body 110 facing the second direction S2, that is, the right side of the first body 100 in the figure.
[0061] There are many options for the structural form of the first driving device. In some embodiments, the electronic device may include: a winch shaft 800, which is arranged on the first sub-body 110, and the winch shaft 800 has a first shaft section and a second shaft section; a force pulley 111, which is rotatably arranged on the first sub-body 110; a power cable 910, one end of which is wound around the first shaft section, and the other end is wound around the force pulley 111 and then wound around the second shaft section. The winding directions of the power cable 910 in the first shaft section and the second shaft section are opposite, and the target point of the power cable 910 is fixedly connected to the first anchor point 121 on the second sub-body 120; a first motor 710, which is arranged on the first sub-body 110, is connected to the winch shaft 800 in a transmission manner, and is electrically connected to the controller. Figure 6 , the hoisting shaft 800 and the force pulley 111 are arranged on the first sub-body 110, and the force pulley 111 is equivalent to the fixed pulley on the first sub-body 110. In some embodiments, the hoisting shaft 800 and the force pulley 111 can be installed on a fixed frame 114 fixedly connected to the first sub-body 110. The hoisting shaft 800 and the force pulley 111 are arranged in sequence along the first direction S1, and the target point of the power cable 910 (a certain point on the power cable 910 can be flexibly selected as the target point as needed) is fixedly connected to the first anchor point 121 on the second sub-body 120, so that the power cable 910 can drive the second sub-body 120 to move relative to the first sub-body 110 during the movement. The hoisting shaft 800 is driven to rotate by the first motor 710. During the rotation of the hoisting shaft 800, its first shaft section and second shaft section complete the opposite winding and unwinding process, that is, one of them winds up the power cable 910, and the other releases the power cable 910. It is easy to understand that the movement direction of the second sub-body 120 relative to the first sub-body 110 can be switched between the first direction S1 and the second direction S2 by controlling the forward and reverse rotation of the first motor 710. Of course, in other embodiments, the first driving device can be set to other structural forms, such as driving the first sub-body 110 and the second sub-body 120 to slide relative to each other through a linear motor.
[0062] In some embodiments, the electronic device may include: a steering pulley 122, rotatably disposed on the second sub-body 120; a connector 130, slidably disposed on the second sub-body 120, and fixedly connected to the second portion of the flexible display screen 300; a closed-loop cable 920, one end of which is fixedly connected to a second anchor point 131 on the connector 130, and the other end of which is fixedly connected to a third anchor point 112 on the first sub-body 110 after passing around the steering pulley 122. The steering pulley 122 is disposed on the second sub-body 120, and is equivalent to a movable pulley for the first sub-body 110. The connector 130 is located on the side of the second sub-body 120 that is away from the aforementioned target display area of the flexible display screen 300, see Figure 1 and Figure 6, the flexible display screen 300 is fixedly connected to the connecting member 130 after passing through one end of the second sub-body 120 facing the first direction S1. In some embodiments, the connecting member 130 can be set as a crossbeam frame structure. It is easy to understand that during the sliding of the second sub-body 120 relative to the first sub-body 110 along the first direction S1, the end of the second sub-body 120 facing the first direction S1 pushes the curved portion of the flexible display screen 300 outward, and the connecting member 130 slides relative to the second sub-body 120 along the first direction S1. Conversely, during the sliding of the second sub-body 120 relative to the first sub-body 110 along the second direction S2, the steering pulley 122 moves relative to the first sub-body 110 along the second direction S2, and pulls the connecting member 130 through the closed-loop pull line 920, so that the connecting member 130 slides relative to the second sub-body 120 along the second direction S2 with a part of the flexible display screen 300.

Figure 6 In the case where both the power cable 910 and the closed-loop cable 920 are provided, the closed-loop cable 920 can be arranged in the middle of the first body 100 (the middle refers to the middle of the first body 100 in the direction that satisfies the vertical condition with respect to the first direction S1, i.e. Figure 6 The middle part in the up-down direction of the display), and the two closed-loop pull wires 920 are symmetrically arranged at the positions on both sides of the closed-loop pull wire 920, so as to improve the stability of the movement of the flexible display screen 300.
[0063] In some embodiments, the electronic device may include: a limit sensor fixed to the first sub-body 110, and the limit sensor is triggered when the connecting member 130 moves to the target position of the first sub-body 110. The limit sensor can be set to the limit position to which the connecting member 130 is allowed to move. When the connecting member 130 moves to this position, the limit sensor is triggered to send an in-position signal to the controller. After receiving the in-position signal sent by the limit sensor, the controller controls the first driving device to stop moving, thereby stopping the connecting member 130 from moving. In addition, the safe sliding range of the second sub-body 120 and the first sub-body 110 can also be determined by detecting the positional relationship of the target point of the second sub-body 120 relative to the first sub-body 110. For example, Figure 6 In the illustrated embodiment, a first limit sensor 151 and a second limit sensor 152 distributed along the second direction S2 can be arranged on a sensor bracket 150 fixed to the first sub-body 110, and a sensing element 124 can be arranged on a second guide bar 123 fixed to the second sub-body 120. The sensing element 124 moves with the second sub-body 120. When the sensing element 124 moves to the position of the first limit sensor 151 or the second limit sensor 152, the limit sensor at that position is triggered to send an in-position signal to the controller.
[0064] See also Figure 6In some embodiments, the first sub-body 110 and the second sub-body 120 may be provided with a long strip-shaped slide groove extending along the first direction S1, the first sub-body 110 may be fixedly connected with a first guide bar 113 that slides with the slide groove on the second sub-body 120, and the second sub-body 120 may be fixedly connected with a second guide bar 123 that slides with the slide groove on the first sub-body 110. By providing the guide bars and slide grooves that slide with each other, the relative sliding of the first sub-body 110 and the second sub-body 120 may be more stable. In some embodiments, the slide grooves of the first sub-body 110 and the slide grooves of the second sub-body 120 may be distributed in an interdigitated manner, that is, the slide grooves of the first sub-body 110 and the slide grooves of the second sub-body 120 are alternately arranged in a direction perpendicular to the first direction S1.
[0065] exist Figure 6 In the exemplary embodiment, a part of the flexible display screen 300 slides inside the first body 100, so as to adjust the area of the target display area of the flexible display screen 300 (which can be understood as the part of the flexible display screen 300 exposed on the front of the first body 100). In order to improve the smoothness of the movement and the safety of the flexible display screen 300, a guide roller 140 can be provided at one end of the second sub-body 120 away from the first sub-body 110. The guide roller 140 is rotatably provided on the second sub-body 120, corresponding to the curved part of the flexible display screen 300, and plays the role of guiding the flexible display screen 300 to turn and bend and supporting the flexible display screen 300. In other embodiments, the flexible display screen 300 can also be set as a rolling screen, that is, a part of the flexible display screen 300 rolls inside the first body 100, so as to adjust the area of the target display area of the flexible display screen 300. In this structure, a rotating shaft can be provided on the second sub-body 120 to roll the flexible display screen 300.
[0066] The structural form of the second driving device can be selected in many ways. In some embodiments, the electronic device may include: a screw rod 600, which is arranged on the second body 200, and the axis of the screw rod 600 is parallel to the target axis P; a slider 500, which is threadedly connected to the screw rod 600, and the slider 500 moves along the screw rod 600 based on the rotation of the screw rod 600, and the slider 500 is rotationally connected to the first body 100, and the first body 100 rotates around the target axis P relative to the slider 500; a second motor 720, which is arranged on the second body 200, is transmission-connected to the screw rod 600, and is electrically connected to the controller. Figure 5, the slider 500 is arranged on the second body 200 and connected to the first sub-body 110 through the rotating shaft 400, and the second motor 720 drives the lead screw to rotate. Since the rotation of the slider 500 relative to the second body 200 is limited by the limiting structure of the second body 200 (such as the track groove accommodating the movement of the slider 500), during the rotation of the lead screw, the slider 500 drives the first sub-body 110 to slide relative to the second body 200. It is easy to understand that the movement direction of the first sub-body 110 relative to the second body 200 can be switched between the first direction S1 and the second direction S2 by controlling the forward and reverse rotation of the second motor 720. Of course, in other embodiments, the second driving device can be set to other structural forms, such as driving the first sub-body 110 and the second body 200 to slide relative to each other through an electric cylinder.
[0067] In some embodiments, the electronic device may be configured such that when the target display area of the flexible display screen 300 is adjusted to the maximum area by the relative sliding of the first sub-body 110 and the second sub-body 120, the slider 500 is located in the middle position of the first body 100 in the direction of the relative sliding of the first sub-body 110 and the second sub-body 120. Figure 1 and Figure 5 , when the target display area of the flexible display screen 300 is not expanded to the maximum area, the distances between the slider 500 and the two ends of the first body 100 are not equal, that is, the slider 500 is at an offset position of the first body 100 in the direction of the target axis P, and when the target display area of the flexible display screen 300 is expanded to the maximum area, such as Figure 2 , Figure 3 or Figure 4 As shown, the distances from the slider 500 to the two ends of the first body 100 are equal or approximately equal, that is, the slider 500 is located in the middle position of the first body 100 in the direction of the target axis P.
[0068] See also Figure 7 In some embodiments, the electronic device may include: a position sensor 220, which is disposed on the second body 200 and is electrically connected to the controller. The position sensor 220 is triggered when the slider 500 moves to the target position of the second body 200. By providing the position sensor 220, it is helpful to accurately stop the slider 500 at the specified position. For example, the position sensor 220 can be disposed at the middle position of the second body 200 in the direction of the target axis P. When the electronic device is Figure 1 , Figure 3 or Figure 4 The usage status shown is Figure 2During the adjustment of the use state shown, the slider 500 can accurately stop at the middle position of the second body 200. It should be noted that the position sensor 220 can be arranged on the outer surface or inside of the second body 200, and the present application does not limit this. In addition, the number of position sensors 220 can be more than one, for example, three, which are respectively arranged at the starting position, the middle position and the end position of the movement stroke of the slider 500.
[0069] See also Figure 7 In some embodiments, the electronic device may include: a support member 230, which is rotatably disposed on the second body 200 and is slidably connected to the first sub-body 110, the rotation axis of the support member 230 and the second sub-body 120 relative to each other is parallel to the target axis P, and the direction of relative sliding of the first sub-body 110 and the support member 230 is parallel to the target axis P. In the process of the first body 100 sliding relative to the second body 200, the support member 230 can support the first body 100, so that the first body 100 can slide relative to the second body 200 more stably. Moreover, in the case where the first sub-body 110 and the second body 200 are connected by the slider 500, the support member 230 can support the first body 100 together with the slider 500, which is when the slider 500 is in the offset position of the first body 100 (for example Figure 1 The supporting member 230 reduces the downward movement of the end of the first body 100 farther from the slider 500 relative to the other end, thereby preventing the flexible display screen 300 from displaying the screen content to the user in a skewed posture and affecting the user's usage experience.
[0070] See also Figure 1 to Figure 7 In some embodiments, the second body 200 may include an input component 210, which may be, for example, a keyboard, a touchpad, etc. The input component 210 is arranged on the input surface of the second body 200, and the input surface refers to the side of the second body 200 facing away from the desktop when the second body 200 is placed on the desktop. When the first body 100 and the second body 200 are rotated to an angle of 0°, that is, the first body 100 and the second body 200 are in a stacked state, the input surface of the second body 200 faces the flexible display screen 300.
