[0066] The application discloses an electronic device.

[0067] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only some of the embodiments of the application, but not all the embodiments of the application. The embodiments are provided in the disclosure to make the disclosure thorough and complete and fully express the scope of the disclosure to those skilled in the art. It should be noted that: unless otherwise specified, the relative arrangement of components and steps, the component of materials, the numerical expression and the numerical value described in the embodiments should be interpreted as merely exemplary, but not as a limitation.

[0068] It should be noted that, in the description of the disclosure, unless otherwise specified, the meaning of "a plurality of" is greater than or equal to two; the orientation or position relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is only for the convenience of describing the disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0069] In addition, "first", "second", and similar words used in the disclosure do not represent any order, number or importance, but are only used to distinguish different parts. "Vertical" is not strictly vertical, but within the allowable range of error. "Parallel" is not strictly parallel, but within the allowable range of error. "Include" or "contain" and similar words mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0070] It should also be noted that, in the description of the disclosure, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral connection; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the disclosure can be understood according to the specific circumstances. When it is described that a specific device is located between a first device and a second device, there can be or can not be an intermediate device between the specific device and the first device or the second device.

[0071] All terms used in the present disclosure have the same meaning as understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted in a manner consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or overly formalized sense, unless specifically defined herein.

[0072] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered part of the specification where appropriate. Based on the examples in the present application, all other examples obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0073] Due to the increasing number of posture changes of electronic devices, the relative movement of at least two bodies of the electronic device can not be limited to single reverse movement. Taking an electronic device having a first body and a second body as an example, in a first posture of the electronic device, the first body and the second body can be relatively stacked; in a second posture of the electronic device, the first body and the second body can be moved to a target position (not overlapped). During the switching of the electronic device between the first posture and the second posture, the first body and the second body can have at least two directions of movement.

[0074] In the process of switching from the first posture to the second posture, the second body needs to move relative to the first body along the first direction until there is a gap between the first body and the second body, and then the second body moves along the second direction (e.g., perpendicular to the first direction) to achieve the lifting operation of the second body relative to the first body, so as to move the first body and the second body to the target position. The applicant found that when the gap between the first body and the second body is small, the edge of the second body interferes with or even collides with the edge of the first body when the second body is lifted (moves relative to the first body along the second direction), which can easily damage the first body and the second body, especially when the first body and the second body have a display screen (e.g., LCD (Liquid Crystal Display)) or other components made of glass or other brittle materials, which are more likely to be damaged. When the gap between the first body and the second body is large, although the interference between the first body and the second body is avoided, the distance between the first body and the second body in the second posture is large, which affects the cooperative use of the first body and the second body (e.g., the first body has a main display screen, and the second body has a secondary display screen, the main display screen and the secondary display screen are used to display different positions or contents of output information to realize complete information display).

[0075] Of course, there are other cases, for example, in the process of switching from the first posture to the second posture, the relative position of the first body and the second body along the first direction changes, and the angle between the second body and the first body also changes, that is, in the process of switching from the first posture to the second posture, the second body moves linearly relative to the first body and rotates. Similarly, the applicant found that when the first body and the second body move along the first direction and the gap between the first body and the second body is small, the edge of the second body interferes with or even collides with the edge of the first body; when the gap between the first body and the second body is large, after the second body rotates relative to the first body, the distance between the first body and the second body in the second posture is large, which affects the cooperative use of the first body and the second body.

[0076] As shown in Figures 1-3 , Figures 7-9 , Figures 11-13 The electronic device provided by the embodiment of the present application comprises:

[0077] The first body 100 can be a part of the electronic device that does not move with the posture change of the electronic device when placed on a bearing surface (a desktop or a placement platform, etc.). Taking a notebook computer as an example, the first body 100 can be a body with a touchpad or a keyboard, etc. Taking a display as an example, the first body 100 can be fixed relative to a display screen support. The structure shown by the reference numeral "100" in the above figure can be a part of the first body 100, and the first body 100 can further include components (such as a display screen, etc.) that are not shown in the figure.

[0078] The second body 200 can be a component that moves relative to the first body 100 during the posture change of the electronic device, wherein the second body 200 can have a relative motion such as sliding or rotating with the first body 100, and the first body 100 and the second body 200 can be directly movably connected or indirectly movably connected through other components.

[0079] The second body 200 can have a first position, a second position, and a third position switchable along a first direction X relative to the first body 100. Wherein, Figures 1-3 is a structural schematic view of the second body 200 in the first position along the first direction X relative to the first body 100, Figures 7-9 is a structural schematic view of the second body 200 in the second position along the first direction X relative to the first body 100, Figures 11-13 is a structural schematic view of the second body 200 in the third position along the first direction X relative to the first body 100. As Figure 2 , Figure 8 and Figure 12 indicated, in the case that the position of the first body 100 does not change, the second body 200 will move along the first direction X during the switching between the first position, the second position, and the third position. Wherein the first direction X can be a straight line direction, a rotating direction, or a direction along a predetermined trajectory, etc.

[0080] And the second body 200 can have a fourth position and a fifth position switchable along a second direction Y relative to the first body 100. Taking the second body 200 being lifted relative to the first body 100 as an example, that is, the second direction Y can be a straight line direction perpendicular to the first direction X. As Figure 9 indicated, in the state that the second body 200 has the fourth position along the second direction Y relative to the first body 100, the distance between the bottom surface (such as the downward surface in Figure 9 ) of the first body 100 and the top surface (the second functional surface 210, such as the upward surface in Figure 9 ) of the second body 200 is H1; as Figure 13As shown, when the second body 200 is in a fifth position relative to the first body 100 along the second direction Y, the bottom surface of the first body 100 (as shown) Figure 10 The face facing down) and the top surface of the second body 200 (the second functional surface 210, such as...) Figure 10 The distance between the faces (facing upwards) is H2, where H1 is different from H2. Alternatively, the second direction Y can be a rotational direction or a direction formed along the target trajectory.

[0081] Therefore, it can be seen that the first body 100 and the second body 200 can have relative movements along the first direction X and the second direction Y. Taking a first posture and a second posture of the first body 100 and the second body 200 as examples, in the first posture, the second body 200 is in a first position relative to the first body 100 along the first direction X and in a fourth position relative to the first body 100 along the second direction Y; in the second posture, the second body 200 is in a third position relative to the first body 100 along the first direction X and in a fifth position relative to the first body 100 along the second direction Y. The second position relative to the first body 100 along the first direction X can be an intermediate state for the electronic device switching between the first posture and the second posture.

[0082] In the first position, the second body 200 can be restricted by the first body 100 in the second direction Y to be in the fourth position; that is, when the second body 200 is in the first position relative to the first body 100 in the first direction X, due to the relative positional relationship between the second body 200 and the first body 100 in the first direction X, the second body 200 can be restricted by the first body 100 in the second direction Y and cannot switch between the fourth position and the fifth position, so that the second body 200 is in the fourth position.

[0083] In the second position, the second body 200 can switch from the fourth position to the fifth position in the second direction Y; that is, when the second body 200 is in the second position relative to the first body 100 along the first direction X, due to the relative positional relationship between the second body 200 and the first body 100 in the first direction X, the second body 200 is not restricted by the first body 100 in the second direction Y, so as to switch between the fourth position and the fifth position.

[0084] The position switching of the second body 200 in the first direction X and the second direction Y can be performed simultaneously, for example, the second body 200 can be switched from the second position to the third position along the first direction X, and at the same time, the second body 200 can be switched from the fourth position to the fifth position along the second direction Y. That is, the second body 200 can be switched from the second position to the third position along the first direction X, and at the same time, the second body 200 can be switched from the fourth position to the fifth position along the second direction Y.

[0085] The position switching of the second body 200 in the first direction X and the second direction Y can be performed simultaneously, for example, the second body 200 can be switched from the second position to the third position along the first direction X, and at the same time, the second body 200 can be switched from the fourth position to the fifth position along the second direction Y. That is, the second body 200 can be switched from the second position to the third position along the first direction X, and at the same time, the second body 200 can be switched from the fourth position to the fifth position along the second direction Y.

[0086] In the case that the second body 200 is in the fifth position along the second direction Y, the second body 200 can be switched from the second position to the third position, and the third position can be located between the first position and the second position along the first direction X. That is, in the case that the second body 200 is in the fifth position along the second direction Y, the second body 200 is in the third position along the first direction X. Since the third position is located between the first position and the second position along the first direction X, the second position is a position at which the first body 100 and the second body 200 are far apart along the first direction X, so as to provide sufficient space for the position switching of the second body 200 along the second direction Y, and avoid the interference between the first body 100 and the second body 200. In addition, compared with the second position, the third position is a position at which the first body 100 and the second body 200 are close to each other along the first direction X, so as to facilitate the use of the second body 200 (such as the cooperative use of the first body 100 and the second body 200, etc.).

[0087] In some embodiments, in the process of switching from the first position to the third position, the second body 200 can be moved from the first position to the second position along the first direction X, and then moved to the third position along the first direction X, that is, the second position is an intermediate position, and in the process of switching from the first position to the third position along the first direction X, the second body 200 will pass through the second position. In addition, in the process of switching from the third position to the first position, the second body 200 will pass through the second position. That is, the second body 200 can be moved from the third position to the second position along the first direction X, and then moved to the first position along the first direction X. Since the third position is located between the first position and the second position along the first direction X, the moving direction of the second body 200 from the first position to the second position along the first direction X is opposite to the moving direction of the second body 200 from the first position to the third position along the first direction X.

[0088] In the first position, the first body 100 and the second body 200 can at least partially overlap in projection along the second direction Y; that is, the first body 100 and the second body 200 at least partially overlap along the second direction Y. In this state, the thickness of the electronic device can include the thickness of the overlapping part of the first body 100 and the second body 200. In the first attitude of the electronic device, the second body 200 is in the first position relative to the first body 100 along the first direction X, and the at least partial overlap of the first body 100 and the second body 200 along the second direction Y in this state can reduce the size of the electronic device along the first direction X of the first body 100 and the second body 200.

[0089] In the second position, the first body 100 and the second body 200 can have a first gap between the projections along the second direction Y; that is, the first body 100 and the second body 200 are relatively independent and do not overlap along the second direction Y. In this state, the thickness of the electronic device can include the thickness of the first body 100 or the second body 200. As shown in Figure 8 , the first gap can be L1, and the specific value of L1 can be 3mm, 5mm or 10mm, etc. As shown in Figure 19 and Figure 20 , the first body 100 has a first functional surface 101, and the second body 200 has a second functional surface 210. In the case of a first gap between the first body 100 and the second body 200, there is a gap between the first functional surface 101 and the second functional surface 210, and a whole plane cannot be formed.

[0090] In the third position, the first body 100 and the second body 200 can have a second gap between the projections along the second direction Y, and the second gap is smaller than the first gap. That is, the first body 100 and the second body 200 are relatively independent and do not overlap along the second direction Y. In this state, the thickness of the electronic device can include the thickness of the first body 100 or the second body 200. As shown in Figure 12 , the second gap can be L2, and the specific value of L2 can be 0mm, 2mm or 7mm, etc. Wherein, when the second gap is L2=0, it is equivalent to the first body 100 and the second body 200 being in abutment, so that the faces of the first body 100 and the second body 200 towards the second direction Y can be abutted as a whole face. As shown in Figure 21 and Figure 22As shown, the first body 100 has a first functional surface 101, and the second body 200 has a second functional surface 210. In the case of L2=0, the edge of the first functional surface 101 facing the second body 200 can contact the edge of the second functional surface 210 facing the first body 100, so that the first functional surface 101 and the second functional surface 210 form an integral large functional surface, so as to increase the area of functional action. The functional action can include information input (such as a touchpad) or information output (such as a display surface), etc.

[0091] Since the third position can be between the first position and the second position in the first direction X, the second body 200 is farther away from the first body 100 in the case of the third position than in the case of the first position.

[0092] In the third position, the second body 200 can be limited in the fifth position by the first body 100 in the second direction Y for the stability of the second body 200 in the fifth position. That is, in the case that the second body 200 is in the third position relative to the first body 100 in the first direction X, due to the relative position relationship between the second body 200 and the first body 100 in the first direction X, the second body 200 can be limited by the first body 100 in the second direction Y and cannot switch between the fourth position and the fifth position, so that the second body 200 is in the fifth position.

[0093] The second body 200 can also be able to switch between the fourth position and the fifth position in the second direction Y in the third position.

[0094] The movement of the second body 200 relative to the first body 100 can be manually exerted by a force. In order to improve the stability of the force exerted on the second body 200, a driving unit 300 capable of providing a first force can also be provided.

[0095] In some embodiments, the electronic device can include a driving unit 300 capable of providing a first force moving in the first direction X; wherein in the first position, the first force can drive the second body 200 to move in the first direction X, so that the second body 200 moves to the second position. That is, the direction of the first force is the first direction X, and the first force exerted by the driving unit 300 drives the second body 200 to move to the second position in the first direction X.

[0096] It can be understood that the component powered by the driving unit 300 is taken as an example of the motor, the second position is the position reached by the second body 200 in the intermediate state, and the second body 200 is difficult to be accurately moved to the second position by controlling the start and stop of the motor without setting other limiting structures. Therefore, the first driving force applied by the driving unit 300 can drive the second body 200 to be switchable to the first position, the second position and the third position along the first direction X relative to the first body 100, that is, the first driving force can drive the second body 200 to switch from the first position to the third position, passing through the second position in the middle. Therefore, in the second position, the first driving force can also drive the second body 200 to move to the third position along the first direction X. That is, the first driving force of the driving unit 300 can drive the second body 200 to move to the first position, the second position and the third position along the first direction X relative to the first body 100.

[0097] A plurality of driving mechanisms can also be provided, one of which is the driving unit 300 capable of applying the first driving force to drive the second body 200 to move from the first position to the second position along the first direction X, and the other driving mechanisms are capable of applying other driving forces to drive the second body 200 to move from the second position to the third position along the first direction X.

[0098] In some embodiments, the first driving force can drive the second body 200 to move along the second direction Y, so as to switch the second body 200 from the fourth position to the fifth position along the second direction Y. That is, the power for moving the second body 200 along the first direction X and along the second direction Y is the first driving force provided by the driving unit 300, avoiding the additional setting of the driving structure for moving the second body 200 along the second direction Y.

[0099] Other driving structures capable of applying the second driving force along the second direction Y can also be provided separately, which are not limited herein and are within the protection scope.

[0100] In some embodiments, the electronic device can include a transmission assembly 400, which can connect the driving unit 300 and the second body 200.

[0101] The transmission assembly 400 can include a pullback unit 410 and a switching unit 420. The pullback unit 410 can connect the driving unit 300 and the second body 200, and the pullback unit 410 can realize a pullback effect and drive the second body 200 to move in a direction opposite to the direction of the first driving force (along the first direction X).

[0102] In the embodiment that the second body 200 is moved along the first direction X relative to the first body 100 by the first force of the driving unit 300 and sequentially moves to the first position, the second position and the third position, since the third position is between the first position and the second position along the first direction X, in the case that the direction of the first force is the direction from the first position to the second position, the first force can drive the second body 200 to move from the first position to the second position along the first direction X without the participation (pull back) of the pull back unit 410, while in the process that the second body 200 moves from the second position to the third position, the pull back unit 410 needs to pull back the second body 200 to enable the second body 200 to move along the opposite direction of the first force under the action of the first force.

[0103] In the embodiment, the pull back unit 410 can have a first state and a second state, in the first state, the size of the pull back unit 410 along the first direction X is constant under the action of the first force, while in the second state, the size of the pull back unit 410 along the first direction X changes (such as decreases) under the action of the first force. The switching unit 420 is connected with the pull back unit 410 through the connecting rod component 430 to facilitate the switching of the pull back unit 410 between the first state and the second state.

[0104] In order to facilitate the slim design of the electronic device, it is generally necessary to reduce the stacking of the components in the thickness direction (the second direction Y), therefore, in the embodiment, the projection area of the pull back unit 410 along the second direction Y can be independent of the projection area of the switching unit 420 to avoid the stacking of the pull back unit 410 and the switching unit 420 along the thickness direction (the second direction Y) of the electronic device, which reduces the size requirement of the electronic device in the thickness direction, thereby facilitating the reduction of the thickness of the electronic device.

[0105] In some embodiments, when the second body 200 moves from the first position to the second position along the first direction X, the switching unit 420 can drive the pull back unit 410 to switch from the first state to the second state through the connecting rod component 430, and the size of the pull back unit 410 along the first direction X changes to drive the second body 200 to move to the third position.

[0106] In the embodiment, the size change of the pull back unit 410 along the first direction X can be telescopic deformation or a rotating connection.

[0107] Taking the pull back unit 410 as an example that can be telescopic along the first direction X, the pull back unit 410 can include a scissors structure 411 movably connected between the second body 200 and the driving unit 300, wherein in the second state, the scissors structure 411 can be telescopic along the first direction X under the action of the first force to drive the second body 200 to move from the second position to the third position.

[0108] The support member or the like structure that can be additionally supported between the second body 200 and the driving unit 300 can be used to achieve the relative limiting and unlimiting of the second body 200 and the driving unit 300. In the first state, the support member can be supported between the second body 200 and the driving unit 300 to avoid the telescopic change of the scissor structure 411; in the second state, the support member can be moved relative to the second body 200 and the driving unit 300, so that the second body 200 and the driving unit 300 can be relatively moved to enable the telescopic change of the scissor structure 411. The switching unit 420 can control the support or non-support of the support member through the connecting rod member 430.

[0109] Of course, the switching unit 420 can also be used to achieve the relative limiting and unlimiting of the second body 200 and the driving unit 300.

[0110] The pullback unit 410 can also include a tension spring or a gear and rack structure, which is not specifically limited herein and is within the protection scope.

[0111] In order to further facilitate the slim design, the axis direction of the two connecting rods rotatably connected in the scissor structure 411 can be the second direction Y, that is, in the telescopic change process of the scissor structure 411, the connecting rods can rotate along the axis in the second direction Y, without changing the size of the scissor structure 411 in the second direction Y, thereby reducing the size requirement of the electronic device in the thickness direction (the second direction Y).

[0112] In some embodiments, the scissor structure 411 can include a first connecting rod 4112, a second connecting rod 4114, and an intermediate connecting rod 4113. The first connecting rod 4112 can be rotatably connected with the first member 441; the second connecting rod 4114 can be rotatably connected with the second member 220; and the intermediate connecting rod 4113 can be rotatably arranged between the first connecting rod 4112 and the second connecting rod 4114, and the rotating connection part 4110 can be located in the intermediate connecting rod 4113. The first connecting rod 4112, the intermediate connecting rod 4113, and the second connecting rod 4114 are sequentially connected to form a connecting rod group, and the scissor structure 411 can have at least two groups of symmetrically arranged connecting rod groups. The above connecting rod group can also be composed of two connecting rods, four connecting rods, or other number of connecting rods, which is not specifically limited herein and is within the protection scope.

[0113] In the process of moving the second body 200 from the second position to the third position, the first member 441 can move along the first direction X to make the intermediate connecting rod 4113 rotate relative to the main body member 421 and the rotating connection part 4110 and the second member 220 approach the first member 441.

[0114] In some embodiments, the electronic device may include a guide structure 500 for guiding the second body 200, thereby enabling switching between a fourth position and a fifth position.

[0115] To facilitate the slim design of electronic devices, it is generally necessary to reduce the stacking of components in the thickness direction (second direction Y). Therefore, in this embodiment, along the second direction Y, the projection area of ​​the guide structure 500, the projection area of ​​the pull-back unit 410, and the projection area of ​​the switching unit 420 are independent of each other, so as to avoid the guide structure 500, the pull-back unit 410, and the switching unit 420 being stacked along the thickness direction (second direction Y) of the electronic device, thereby reducing the size requirements of the electronic device in the thickness direction and thus facilitating the reduction of the thickness of the electronic device.

[0116] like Figure 17 and Figure 18 As shown, during the switching process of the second body 200 between the second and third positions along the first direction X, the guide structure 500 can guide the second body 200 to move along the guide trajectory, so that the second body 200 can switch between the fourth and fifth positions along the second direction Y. Specifically, under the action of the first force, during the switching process of the second body 200 from the second position to the third position along the first direction X, the guide structure 500 can guide the second body 200 to move along the guide trajectory, so that the second body 200 can move from the second position to the third position along the first direction X and from the fourth position to the fifth position along the second direction Y. Through the above configuration, the first force, in conjunction with the guide structure 500, can realize the switching of the second body 200 between the fourth and fifth positions. Of course, other triggering devices can also be provided, and the first force can unlock the triggering device, allowing the triggering device to exert other forces on the second body (such as a second force along the second direction Y), so that the second body 200 can switch between the fourth and fifth positions. The triggering device can be a compression spring or elastic block in an energy storage state.

[0117] The guide structure 500 may include a guide groove 510 and a guide protrusion 520. In the second position, one of the guide groove 510 and the guide protrusion 520 may be fixed relative to the second body 200, and the other of the guide groove 510 and the guide protrusion 520 may be fixed relative to the first body 100. The guide groove 510 may form a certain angle with both the first direction X and the second direction Y, so that the second body 200 can move along the first direction X and the second direction Y as the guide protrusion 520 moves along the guide groove 510. The guide groove 510 may be a straight groove or an arc-shaped groove; no specific limitation is made here, and both are within the scope of protection.

[0118] In this embodiment, the other of the guide groove 510 and guide protrusion 520 can be connected to the main body component 421, and in the second position, the main body component 421 is positioned relative to the first body 100. One of the guide groove 510 and guide protrusion 520 can be connected to the second component 220.

[0119] The connection end of the scissor lift structure 411 and the second component 220 may have a rotating connector 4111. During the movement of the second body 200 along the guide structure 500, the rotating connector 4111 may rotate relative to the second component 220 to adjust the connection position of the scissor lift structure 411 and the second component 220 in the second direction Y, so as to avoid the scissor lift structure 411 and the guide structure 500 from interfering with each other or getting stuck.

[0120] like Figures 4-6 and Figures 14-16 As shown, the switching unit 420 may include a main body component 421 and a locking component 422. The main body component 421 is movable relative to the first body 100 along the first direction X, and the connecting rod component 430 is movably connected to the main body component 421. The locking component 422 is movably connected to the connecting rod component 430 and has a fifth state and a sixth state. In the fifth state, the locking component 422 connects the main body component 421 and the second body 200. In the sixth state, the main body component 421 is separated from the second body 200.

[0121] During the movement of the second body 200 from the first position to the second position, the relative movement of the rotating engagement part 4110 and the first component 441 can be restricted, and the connection part 4221 of the locking component 422 can be connected to the second component 220. During the movement of the second body 200 from the second position to the third position, the rotating engagement part 4110 and the first component 441 can be brought closer to each other, and the connection part 4221 of the locking component 422 can be separated from the second component 220.

[0122] like Figure 6 As shown, the locking member 422 may have a control part 4222 opposite to the connecting part 4221. The part of the locking member 422 located between the connecting part 4221 and the control part 4222 may be rotatably connected to the main body member 421 to improve the rotational stability of the locking member 422. The second end 432 is connected to the control part 4222. The rotation of the second end 432 drives the control part 4222 to rotate, thereby realizing the position movement of the connecting part 4221, thereby controlling the connection and separation of the connecting part 4221 of the locking member 422 from the second member 220.

[0123] In some embodiments, the locking unit can include a limiting component 423 and an elastic component 424, wherein the limiting component 423 can be rotationally connected with the main body component 421, and the limiting component 423 can be connected with the locking component 422; the elastic component 424 can be used to provide an elastic restoring force to the limiting component 423; during the movement of the second body 200 from the first position to the second position, the connecting portion 4221 is connected with the second component 220, and under the action of the elastic restoring force, the first limiting surface 4231 of the limiting component 423 abuts against the first matching surface 4223 of the locking component 422 to provide a first limiting force to the locking component 422.

[0124] In some embodiments, the locking unit can include a limiting component 423 and an elastic component 424, wherein the limiting component 423 can be rotationally connected with the main body component 421, and the limiting component 423 can be connected with the locking component 422; the elastic component 424 can be used to provide an elastic restoring force to the limiting component 423; during the movement of the second body 200 from the first position to the second position, the connecting portion 4221 is connected with the second component 220, and under the action of the elastic restoring force, the first limiting surface 4231 of the limiting component 423 abuts against the first matching surface 4223 of the locking component 422 to provide a first limiting force to the locking component 422.

[0125] In some embodiments, the main body component 421 can be slidably connected with the first body 100, and the scissors structure 411 can have a rotation matching portion 4110 rotationally connected with the main body component 421; the locking component 422 can be relatively connected with the main body component 421 and has a connecting portion 4221 connectable with the second component 220. The locking component 422 can be connected with the second end 432 of the main body component 421, and the movement of the connecting link component 430 can drive the locking component 422 to rotate, so that the connecting portion 4221 moves relative to the connecting position (such as the arc-shaped groove 222 shown in FIG. 11) of the second component 220 to realize the switching of the locking component 422 between the fifth state and the sixth state by the driving of the connecting link component 430. Figure 17 In some embodiments, the main body component 421 can be slidably connected with the first body 100, and the scissors structure 411 can have a rotation matching portion 4110 rotationally connected with the main body component 421; the locking component 422 can be relatively connected with the main body component 421 and has a connecting portion 4221 connectable with the second component 220. The locking component 422 can be connected with the second end 432 of the main body component 421, and the movement of the connecting link component 430 can drive the locking component 422 to rotate, so that the connecting portion 4221 moves relative to the connecting position (such as the arc-shaped groove 222 shown in FIG. 11) of the second component 220 to realize the switching of the locking component 422 between the fifth state and the sixth state by the driving of the connecting link component 430.

[0126] In the first position, the locking component 422 can be in the fifth state to limit the relative position of the main body component 421 and the second body 200, i.e., the size of the pull-back unit 410 in the first direction X is fixed. Thus, the first acting force can drive the main body component 421 to move in the first direction X through the second body 200 to move the second body 200 to the second position.

[0127] And, in the above process, the main body component 421 can be driven by the connecting rod component 430 to switch the pull-back unit 410 from the first state to the second state. That is, the state switching of the pull-back unit 410 is also realized by the first force. Since the locking component 422 is in the fifth state, the second body 200 is driven to move by the first force to drive the main body component 421 to move, since the connecting rod component 430 connects the main body component 421 and the locking component 422, the connecting rod component 430, the main body component 421 and the locking component 422 all move relative to the first body 100, therefore, the connecting rod component 430 can drive the pull-back unit 410 to switch from the first state to the second state through the relative cooperation of the locking component 422 and the first body 100 or the relative cooperation of the connecting rod component 430 and the first body 100, thereby realizing the state switching of the pull-back unit 410, avoiding the additional setting of the power component for switching the state of the pull-back unit 410.

[0128] In the second position, the connecting rod component 430 can drive the locking component 422 to switch to the sixth state, so that the second body 200 moves relative to the main body component 421 and moves to the third position. The state switching of the locking component 422 can be realized by the connecting rod component 430, that is, the state switching of the locking component 422 can be indirectly realized by the first force, which also reduces the power component for switching the state of the locking component 422.

[0129] As shown in Figure 5 , Figure 6 and Figure 16 , in some embodiments, the connecting rod component 430 can have a first end 431 and a second end 432 opposite to each other; the main body component 421 and the connecting rod component 430 can slide relative to each other.

[0130] Wherein, the first component 441 can have a third guide structure 4411, the third guide structure 4411 can slide with the first end 431, and the third guide structure 4411 can have a first guide segment 44111 and a second guide segment 44112 connected with each other. The second guide segment 44112 can be arranged along the first direction X, and the first guide segment 44111 and the second guide segment 44112 can satisfy the perpendicular condition. That is, the first guide segment 44111 and the second guide segment 44112 can be L-shaped structures, the extension direction of the first guide segment 44111 is perpendicular to the first direction X, and the extension direction of the second guide segment 44112 can be parallel to the first direction X, that is, in the state that the second body 200 moves along the first direction X, in the state that the first end 431 cooperates with the first guide segment 44111, the first component 441 moves synchronously with the first end 431 of the connecting rod component 430; in the state that the first end 431 cooperates with the second guide segment 44112, the first component 441 and the first end 431 of the connecting rod component 430 slide with each other.

[0131] The first body 100 can have a fourth guide structure 110 which can be slidably fitted with the second end 432, the fourth guide structure 110 can have a third guide segment 111 and a fourth guide segment 112 which are connected with each other, the third guide segment 111 can be arranged along the first direction X, and the third guide segment 111 and the fourth guide segment 112 can have a target angle (such as 120°, 135°, etc.). In the state that the second body 200 moves along the first direction X, the second end 432 of the connecting rod component 430 moves along the fourth guide structure 110, and in the process of switching from the first position to the second position, the second end 432 of the connecting rod component 430 slides along the third guide segment 111, and the position of the first end 431 of the connecting rod component 430 relative to the first component 441 remains unchanged, so that the first end 431 is fitted with the first guide segment 44111. In the process of switching from the second position to the third position, the second end 432 of the connecting rod component 430 moves along the fourth guide segment 112, as shown, the second end 432 moves to the lower right corner of the illustrated position, so as to drive the first end 431 of the connecting rod component 430 to move to the second guide segment 44112, in this state, the connecting part 4221 of the locking component 422 is separated from the second component 220, so that the first component 441 has a movement trend of relatively approaching the second component 220 under the first action force (the first component 441 moves along the horizontal right direction), so that the connecting end (the rotating connecting piece 4111) of the scissors structure 411 connected with the second component 220 can move in the direction of the first component 441 (the horizontal left direction), so as to realize the pullback operation. Figure 5 Figure 6 Figure 6

[0132] That is, in the process of moving the second body 200 from the first position to the second position, the second end 432 moves along the third guide segment 111, the first end 431 is located in the first guide segment 44111, and the connecting rod component 430 is limited relative to the main body component 421, and the relative movement of the rotating fitting part 4110 and the second component 220 is limited; in the process of moving the second body 200 from the second position to the third position, the second end 432 moves along the fourth guide segment 112 to move the connecting rod component 430 relative to the main body component 421, and drive the first end 431 to move along the first guide segment 44111 to the second guide segment 44112, so that the first component 441 and the second component 220 can be relatively close.

[0133] Through the above arrangement, the driving unit 300 providing the first action force can be used as a power source to realize various movements and state switching, effectively improve the utilization rate of the driving unit 300, reduce the number of parts, and thus reduce the space occupied by the electronic device.​​​

[0134] That is, the pullback unit 410 can include a first component 441 connected with the driving unit 300 (the driving end of the driving unit 300 is connected with the power input end of the transmission assembly 400, and the power output end of the transmission assembly 400 has the first component 441), a second component 220 connected with the second body 200, and a scissor structure 411 movably connected between the first component 441 and the second component 220; wherein, when the switching unit 420 controls the pullback unit 410 to be in the first state, the switching unit 420 limits the relative movement of the first component 441 and the second component 220, so that the structure of the pullback unit 410 is unchanged; when the switching unit 420 controls the pullback unit 410 to be in the second state, the first component 441 and the second component 220 can relatively approach, so that the pullback unit 410 can be deformed in structure.

[0135] In some embodiments, in order to cooperate with the movement of the connecting rod component 430, the main body component 421 can have a first guide structure 4211 slidably matched with the first end 431 and a second guide structure 4212 slidably matched with the second end 432. The first guide structure 4211 can be a strip-shaped hole extending along a direction perpendicular to the first direction X, and the second guide structure 4212 is an arc-shaped hole, so as to facilitate the movement of the second end 432 along the third guide segment 111 and the fourth guide segment 112 of the fourth guide structure 110, that is, in the process of moving the second end 432 from the third guide segment 111 to the fourth guide segment 112, the second end 432 is slidably matched with the second guide structure 4212.

[0136] In order to play a guiding effect and not interfere with the movement of the first end 431 and the second end 432, in the process of moving the second body 200 from the first position to the second position, the projection of the first guide segment 44111 along the rotation axis direction of the first end 431 and the first component 441 can coincide with the projection of the first guide structure 4211; in the process of moving the second body 200 from the second position to the third position, the second end 432 moves along the third guide segment 111 and the second guide structure 4212.

[0137] In the embodiments of the present application, the first end 431 and the second end 432 can have a rotation shaft or a roller structure, and the axis line thereof is arranged along the second direction Y. Through the rotation of the rotation shaft or the roller, the friction loss between the first end 431 and the second end 432 and the wire structure is further reduced.

[0138] In some embodiments, the switching unit 420 can include a limiting component 423 and an elastic component 424, wherein the limiting component 423 can be rotationally connected with the main body component 421, and the limiting component 423 can be in limiting contact with the locking component 422 in the fifth state and the sixth state; the elastic component 424 is configured to provide an elastic force to the limiting component 423 so that the limiting component 423 provides a limiting force to the locking component 422 through the limiting contact. With the above arrangement, the limiting force can be applied to the locking component 422 through the limiting component 423, and the accuracy of the locking component 422 in the fifth state and the sixth state is improved.

[0139] The elastic component 424 can provide an elastic force in a direction perpendicular to the second direction Y. The elastic component 424 can be elastically deformed along the direction of the elastic force. Since the elastic force is perpendicular to the second direction Y, the size of the second direction Y is not affected, and the thin design of the electronic device can be achieved.

[0140] In the present embodiment, the elastic component 424 can be a torsion spring, one end of which is connected with the limiting component 423, and the other end of which is connected with the main body component 421. The size requirement of the elastic component 424 in the second direction Y is further reduced. The elastic component 424 can also be a telescopic spring or a constant force spring, which is not limited herein and is within the protection scope.

[0141] In some embodiments, the first body 100 and the second body 200 of the electronic device can each have a functionality, and the functionalities can be used together or separately.

[0142] The first body 100 can have a first functional surface (not shown), and the second body 200 can have a second functional surface 210. The orientations of the first functional surface and the second functional surface 210 satisfy a same direction condition. The same direction condition means that the orientations of the first functional surface and the second functional surface 210 can satisfy that a user can observe or operate the first functional surface and the second functional surface 210 at the target position at the same time. The orientations of the first functional surface and the second functional surface 210 can be the same or can form a certain angle.

[0143] In the fourth position, the first functional surface and the second functional surface 210 can have a height difference. In the fifth position, the first functional surface and the second functional surface 210 can satisfy a coplanar condition. The coplanar condition includes that the first functional surface and the second functional surface 210 are located in the same plane, or the height difference between the first functional surface and the second functional surface 210 is less than or equal to a target size (e.g., 5 mm), which does not affect the user to use the first functional surface and the second functional surface 210 that satisfy the coplanar condition cooperatively.

[0144] The second body 200 and the transmission assembly 400 can be connected through the second component 220.

[0145] In some embodiments, the transmission assembly 400 can include a transmission unit 440, the transmission unit 440 can include a power input end connected with the driving end of the driving unit 300 and a power output end (a first part 441) capable of moving in the first direction X, the power output end is used for connecting with the second body 200; wherein the power input end of the transmission assembly 400 inputs a first stroke, the power output end of the transmission assembly 400 can output a second stroke, the second stroke can be greater than the first stroke. By setting the transmission unit 440, the stroke demand of the driving end of the driving unit 300 is reduced on the premise of meeting the stroke demand (second stroke) of the second body 200, so as to improve the movement speed of the second body 200 under the condition that the driving end speed of the driving unit 300 is unchanged, so as to improve the switching speed of the second body 200 at different positions. And under the condition of meeting the movement speed of the second body 200, the movement speed of the driving end of the driving unit 300 can be reduced, so that the driving end of the driving unit 300 can be more accurately adjusted, so as to reduce vibration and the like. And a driving unit 300 with smaller stroke demand (such as a motor) can be used, so as to reduce the size of the driving unit 300 and optimize the space layout.

[0146] Wherein, the arrangement direction of the transmission unit 440 and the driving unit 300 can be perpendicular to the second direction Y. Through the above setting, the transmission unit 440 and the driving unit 300 can be avoided to be stacked in the second direction Y, and the size demand of the electronic device in the thickness direction (second direction) is reduced.

[0147] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0148] The above description of the disclosed embodiments enables a person skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
