Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic devices, and in particular, to a lifting mechanism, a housing, and an electronic device. Background Art

[0002] As the power consumption of tablet computers is increasing and their performance is improving, the requirement for heat dissipation is also getting higher. The heat generated by high power consumption cannot be dissipated, which has become one of the bottlenecks restricting the performance improvement of tablet computers. Heat dissipation performance has also become a key indicator for tablet computers. In related technologies, heat dissipation holes are usually provided on the outer shell of tablet computers. However, the thickness of the tablet computers in related technologies is relatively large, which is not conducive to achieving the thin and light design of the whole machine. Summary of the Invention

[0003] The embodiments of the present application provide a lifting mechanism, a housing, and an electronic device, which are used to improve the problem of the relatively large thickness of electronic devices in related technologies.

[0004] To achieve the above object, the embodiments of the present application provide the following solutions:

[0005] On the one hand, the embodiments of the present application provide a lifting mechanism, which includes a base, a flipping bracket, a lifting bracket, and a linkage assembly. The base includes opposite first and second surfaces, and the direction from the second surface to the first surface is the lifting direction; the flipping bracket includes a first connection end and a first free end, and the first connection end is rotatably connected to the base; the lifting bracket includes a second connection end and a second free end, and the second connection end is movably connected to the base; the linkage assembly connects the flipping bracket and the lifting bracket. During the actual use of the lifting mechanism, the base can be connected to the structural member of the electronic structure, the first free end of the flipping bracket can be connected to the support housing of the electronic structure, and the second free end of the lifting bracket can be connected to the heat dissipation housing of the electronic structure. Through the above settings, when the flipping bracket rotates relative to the base, the flipping bracket can drive the support housing to rotate relative to the structural member; when the lifting bracket moves relative to the base, the lifting bracket can drive the heat dissipation housing to move relative to the structural member.

[0006] When the lifting mechanism is in the closed state, in the lifting direction, the distance between the first free end of the flipping bracket and the second surface is a first distance, and the distance between the second free end of the lifting bracket and the second surface is a second distance. When the lifting mechanism is in the open state, in the lifting direction, the distance between the first free end of the flipping bracket and the second surface is a third distance, and the distance between the second free end of the lifting bracket and the second surface is a fourth distance, and the third distance is greater than the first distance, and the fourth distance is greater than the second distance. During the process of the lifting mechanism transitioning from the closed state to the open state, the flipping bracket rotates towards the lifting direction, and the flipping bracket drives the lifting bracket to move in the lifting direction through the linkage assembly.

[0007] In summary, when the lifting mechanism is in the closed state, in the lifting direction, the distance between the first free end of the flipping bracket and the second surface is small, and the distance between the second free end of the lifting bracket and the second surface is small, so that the flipping bracket drives the support housing to close relative to the structural member, and the lifting bracket drives the heat dissipation housing to close relative to the structural member. This is beneficial to saving the occupied space of the electronic device and reducing the thickness of the electronic device when the electronic device is in the closed state. When the lifting mechanism is in the open state, in the lifting direction, the distance between the first free end of the flipping bracket and the second surface is large, and the distance between the second free end of the lifting bracket and the second surface is large, so that the flipping bracket drives the support housing to open relative to the structural member, and the lifting bracket drives the heat dissipation housing to open relative to the structural member. This is beneficial for the support housing to support the electronic device, and at the same time, it increases the air volume between the heat dissipation housing and the structural member, which is beneficial to improving the heat dissipation efficiency of the electronic device.

[0008] In some implementation manners, the rotation axis of the flipping bracket relative to the base is the first axis, the lifting bracket is rotatably connected to the base, and the rotation axis of the lifting bracket relative to the base is the second axis, and the second axis is parallel to the first axis. Through the above arrangement, one end of the lifting bracket is rotatably connected to the base, the other end of the lifting bracket can be connected to the heat dissipation housing, and the other end of the lifting bracket moves relative to the base driven by the linkage assembly, so that the other end of the lifting bracket drives the heat dissipation housing to open or close relative to the base. At the same time, since the second axis is parallel to the first axis, the rotation axis of the support housing relative to the base is parallel to the rotation axis of the heat dissipation housing relative to the base, which is beneficial to improving the structural compactness of the lifting mechanism.

[0009] In some implementation manners, the base has a first arc-shaped chute, and the first connection end of the flipping bracket has a first arc-shaped slider, and the first arc-shaped slider is slidably connected to the first arc-shaped chute. Through the above arrangement, the base and the flipping bracket can be rotatably connected together in a rotational connection manner of a virtual axis. When the first arc-shaped slider of the flipping bracket slides in the first arc-shaped chute, the flipping bracket rotates relative to the base.

[0010] In some implementation manners, the lifting bracket includes a lifting chute. In the direction close to the second axis, the lifting chute has an inclined chute section that inclines towards the direction close to the second surface. The first end of the linkage assembly is fixedly connected to the flipping bracket, the second end of the linkage assembly is slidably connected to the lifting chute, and the linkage assembly is also slidably connected to the base along a first direction, and the first direction is parallel to the second surface and perpendicular to the second axis. Through the above arrangement, the linkage between the flipping bracket and the lifting bracket can be realized. When the electronic device is in the open state, the flipping bracket drives the support housing to open relative to the structural member, and the lifting bracket drives the heat dissipation housing to open relative to the structural member. While the support housing can support the electronic device, the heat dissipation housing can also improve the heat dissipation efficiency of the electronic device.

[0011] In some implementations, the linkage assembly includes a first shaft core, a first connecting rod, and a second connecting rod. The first shaft core is fixedly connected to the flipping bracket, and the axial direction of the first shaft core is parallel to the first axis. The first end of the first connecting rod is sleeved on the first shaft core and rotatably connected to the first shaft core, and the first end of the first connecting rod is in clearance fit with the first shaft core. The second connecting rod is slidably connected to the base along the first direction, the first end of the second connecting rod is rotatably connected to the second end of the first connecting rod, the second end of the second connecting rod is located on the side of the first connecting rod away from the first shaft core, and the second end of the second connecting rod is slidably connected to the lifting chute. To sum up, when the flipping bracket rotates in the direction away from the base towards the supporting base surface, the flipping bracket also drives the first shaft core to move along the first direction, the first shaft core drives the first connecting rod to move along the first direction, and at the same time the first connecting rod also rotates relative to the first shaft core, the first connecting rod drives the second connecting rod to move along the first direction, so that the second connecting rod slides relative to the lifting chute of the lifting bracket, and the lifting bracket rotates in the direction away from the base towards the supporting base surface under the drive of the second connecting rod.

[0012] In some implementations, the base further includes a guiding groove, and the extending direction of the guiding groove is parallel to the first direction. The linkage assembly further includes a second shaft core, the second shaft core is slidably connected to the guiding groove, the axial direction of the second shaft core is parallel to the first axis, the second end of the first connecting rod is sleeved on the second shaft core and rotatably connected to the second shaft core, and the first end of the second connecting rod is sleeved on the second shaft core and rotatably connected to the second shaft core. Through the above arrangement, when the flipping bracket rotates relative to the base, it is beneficial to further ensure that the second connecting rod moves along the first direction.

[0013] In some implementations, the base has a sliding hole penetrating along the first direction, the sliding hole is located on the side of the guiding groove away from the first arc chute, the second connecting rod is slidably connected to the sliding hole, and the second end of the second connecting rod is located on the side of the sliding hole away from the lifting chute. Through the above arrangement, the second connecting rod can be slidably connected to the base along the first direction.

[0014] In some implementations, the lifting mechanism further includes an elastic member, the first end of the elastic member is connected to the base, and the second end of the elastic member is connected to the lifting bracket. When the lifting mechanism is in the closed state, the elastic member is in the first state. When the lifting mechanism is in the open state, the elastic member is in the second state, and the deformation amount of the elastic member in the second state is different from the deformation amount of the elastic member in the first state. Through the above arrangement, when the deformation amount of the elastic member of the lifting mechanism is large, the elastic restoring force of the elastic member is large. Under the action of the elastic restoring force of the elastic member on the lifting mechanism, the lifting bracket is pressed towards or away from the second surface relative to the base, which is beneficial to reducing the fitting clearance between the lifting bracket and other structural members and avoiding shaking when the lifting mechanism moves.

[0015] In some implementations, the elastic member includes a first plate portion, a bent plate portion, and a second plate portion. Both the first plate portion and the second plate portion are parallel to the second surface. The first plate portion is connected to the base, and the second plate portion is connected to the lifting bracket. The bent plate portion is connected between the first plate portion and the second plate portion and bends in a direction close to or away from the second surface. When the lifting mechanism is in the closed state, in the lifting direction, there is a first distance between the first plate portion and the second plate portion. When the lifting mechanism is in the open state, in the lifting direction, there is a second distance between the first plate portion and the second plate portion, and the second distance is greater than the first distance. Through the above arrangement, when the lifting mechanism is in the closed state, the first plate portion can be coplanar with the second plate portion, and in the lifting direction, the first distance is zero. When the lifting mechanism is in the open state, the second plate portion is relatively far from the second surface with respect to the first plate portion. In the lifting direction, the second distance is greater than the first distance, and the elastic restoring force of the bent plate portion acts on the lifting mechanism, causing the lifting bracket to be pressed tightly against the base, which is beneficial to reducing the fitting clearance between the lifting bracket and other structural members and avoiding shaking during the movement of the lifting mechanism.

[0016] In some implementations, the lifting chute further includes a first smooth chute section and a second smooth chute section. The inclined chute section communicates between the first smooth chute section and the second smooth chute section, and the first smooth chute section is farther from the second axis than the second smooth chute section. When the lifting mechanism is in the closed state, the second end of the linkage assembly is located in the first smooth chute section, and the first smooth chute section extends in a first direction. Through the above arrangement, when the flipping bracket is in the closed state relative to the base, since the first smooth chute section extends in the first direction and the second end of the linkage assembly is located in the first smooth chute section, the lifting bracket is also in the closed state relative to the base. When the lifting mechanism is in the open state, the second end of the linkage assembly is located in the inclined chute section and the second smooth chute section, and the second smooth chute section extends in the first direction. During the process of the lifting mechanism transitioning from the closed state to the open state, the second end of the linkage assembly slides from the first smooth chute section, via the inclined chute section, to the second smooth chute section. Through the above arrangement, when the flipping bracket rotates relative to the base, since the second end of the linkage assembly slides in the inclined chute section, it drives the lifting bracket to rotate relative to the base, so that the lifting bracket is also in the open state relative to the base. When the flipping bracket rotates relative to the base by a certain angle, the second end of the linkage assembly slides from the inclined chute section to the second smooth chute section. At this time, since the second smooth chute section extends in the first direction, when the flipping bracket continues to rotate relative to the base, the rotation angle of the lifting bracket relative to the base remains unchanged, and the open state of the lifting bracket relative to the base remains unchanged.

[0017] In some implementations, the lifting mechanism further includes a bushing. The first end of the bushing is sleeved on the first shaft core and is rotatably connected to the first shaft core. The first end of the bushing is in interference fit with the first shaft core. The second end of the bushing is slidably connected to the base in a direction perpendicular to the first axis. Through the above arrangement, the interference fit between the first end of the bushing and the first shaft core can provide torque, enabling the flipping bracket to maintain the required opening and closing angle when rotating relative to the base, and enabling the support housing to stably support the electronic device to prevent the electronic device from tipping over.

[0018] In some implementations, the lifting mechanism further includes a transition slider. The first end of the transition slider is rotatably connected to the base, and the second end of the transition slider is rotatably connected to the flipping bracket. The axis of rotation between the transition slider and the base is the first axis, and the axis of rotation between the transition slider and the lifting bracket is the first axis. A support area is formed between the flipping bracket and the base. Within the support area and in a direction perpendicular to the first axis, the flipping bracket shields the transition slider. Here, the "support area" can be understood as the fan-shaped area sandwiched between the flipping bracket and the base, and the support area is exposed to the user's view. Here, "shield" can be understood as that within the support area and in the perspective perpendicular to the first axis, the flipping bracket covers the transition slider so that the transition slider is not exposed to the user's view. Through the above arrangement, since the flipping bracket covers the transition slider, it is avoided that the user observes the phenomenon that the rotation angles of the transition sliders in multiple lifting mechanisms are not synchronized, which is beneficial to improving the aesthetics of the lifting mechanism.

[0019] In some implementations, the flipping bracket further has a second arc-shaped chute, which is adjacent to the first arc-shaped slider. The second end of the transition slider has a second arc-shaped slider, and the second arc-shaped slider is slidably connected to the second arc-shaped chute. Through the above arrangement, the flipping bracket and the transition slider can be rotatably connected together in a rotational connection manner of a virtual axis. The base further has a third arc-shaped slider, which is adjacent to the first arc-shaped chute. The first end of the transition slider has a third arc-shaped chute and a fourth arc-shaped slider, and the third arc-shaped chute is adjacent to the fourth arc-shaped slider. The third arc-shaped slider is slidably connected to the third arc-shaped chute, and the fourth arc-shaped slider and the first arc-shaped slider are both located in the first arc-shaped chute and the fourth arc-shaped slider is slidably connected to the first arc-shaped chute. Through the above arrangement, the base and the transition slider can be rotatably connected together in a rotational connection manner of a virtual axis. In the direction parallel to the first axis, the first end of the transition slider is flush with the first arc-shaped slider, or the first arc-shaped slider extends beyond the first end of the transition slider. Through the above arrangement, within the support area and in the perspective perpendicular to the first axis, the flipping bracket covers the transition slider so that the transition slider is not exposed to the user's view.

[0020] In some implementations, the second arc-shaped chute includes a first arc-shaped surface and a second arc-shaped surface that are oppositely arranged. The first arc-shaped surface is farther from the first axis than the second arc-shaped surface, and the first arc-shaped surface is adjacent to the first arc-shaped slider. A part of the first arc-shaped surface is recessed away from the first axis to form an arc-shaped mating chute. The transition slider has an arc-shaped slide rail that is arranged along the circumferential direction of the transition slider, and the arc-shaped slide rail is slidably connected to the arc-shaped mating chute. Through the above arrangement, when the flipping bracket rotates relative to the transition slider, the transition slider is prevented from deflecting under the lateral force, which is beneficial to improving the rotational reliability between the flipping bracket and the transition slider.

[0021] In some implementations, the orthographic projection of the second axis on the reference plane coincides with the orthographic projection of the first axis on the reference plane, and the reference plane is parallel to the second surface. Through the above arrangement, it is beneficial to improve the structural compactness of the lifting mechanism.

[0022] In some implementations, the second axis is located between the first free end and the second free end. Through the above arrangement, the rotation direction of the support housing relative to the base is opposite to the rotation direction of the heat dissipation housing relative to the base, and during the process of the electronic device transitioning from the closed state to the open state, interference between the support housing and the heat dissipation housing is avoided.

[0023] On the other hand, a housing is provided, which includes a lifting mechanism, a structural member, a support housing, and a heat dissipation housing as described in any of the above embodiments. Among them, the support housing and the heat dissipation housing are located on the same side of the structural member. The support housing is rotatably connected to the structural member. The flipping bracket of the lifting mechanism is located between the structural member and the support housing. The heat dissipation housing is rotatably connected to the structural member. The lifting bracket of the lifting mechanism is located between the structural member and the heat dissipation housing. The base is connected to the structural member. The flipping bracket is connected to the support housing. The lifting bracket is connected to the heat dissipation housing.

[0024] When the lifting mechanism is in the closed state, the support housing is closed relative to the structural member through the lifting mechanism, and the heat dissipation housing is closed relative to the structural member through the lifting mechanism. When the lifting mechanism is in the open state, the support housing is opened relative to the structural member through the lifting mechanism, and the support housing is used to support the structural member. The heat dissipation housing is opened relative to the structural member through the lifting mechanism, and the heat dissipation housing has heat dissipation holes communicating with the external environment. The housing provided by the embodiments of the present application includes the lifting mechanism as described above, and thus has all the above beneficial effects, which will not be elaborated here.

[0025] In some implementations, the heat dissipation housing includes a cover plate and side plates. The side plates are disposed around the edge of the cover plate, and the side plates are located on the side of the cover plate facing the structural member. The side plates have through heat dissipation holes. When the lifting mechanism is in the closed state, the heat dissipation holes are located within the orthographic projection of the structural member on the side plates. Through the above arrangement, the structural member shields the heat dissipation holes on the side plates, which is beneficial to reducing the thickness of the electronic device when the electronic device does not need heat dissipation. When the lifting mechanism is in the open state, at least part of the heat dissipation holes are located outside the orthographic projection of the structural member on the side plates. Through the above arrangement, the heat dissipation holes on the side plates are exposed, which is beneficial to improving the heat dissipation efficiency of the electronic device when the electronic device needs heat dissipation.

[0026] On the other hand, an electronic device is provided, including a housing as in any of the above embodiments, and a display module. The display module is connected to the structural member of the housing and is located on the side of the structural member away from the support housing and the heat dissipation housing. The electronic device provided by the embodiments of the present application includes the housing as described above, and thus has all the above beneficial effects, which will not be elaborated here.

[0027] On the other hand, a housing is provided, including a lifting mechanism, a structural member, and a heat dissipation housing. Among them, the heat dissipation housing is rotatably connected to the structural member, and the lifting mechanism is located between the structural member and the heat dissipation housing. The lifting mechanism includes a driving member and a pushing block. The driving member is connected to the structural member, the pushing block is connected to the driving member, and the pushing block has a first inclined surface. The side of the heat dissipation housing facing the structural member has a second inclined surface that cooperates with the first inclined surface. During the process of the lifting mechanism switching between the closed state and the open state, the driving member drives the pushing block to move in a direction parallel to the structural member.

[0028] Through the above arrangement, when the pushing block moves in a direction parallel to the structural member, the first inclined surface moves in a direction parallel to the structure, so that the second inclined surface slides relative to the first inclined surface, and further enables the heat dissipation housing to open relative to the structural member, increasing the air volume between the heat dissipation housing and the structural member, which is beneficial to improving the heat dissipation efficiency of the electronic device. When the pushing block moves in a direction parallel to the structural member and in the opposite direction, the heat dissipation housing is closed relative to the structural member.

[0029] In some implementations, the driving member includes a driving motor and a lead screw. The driving shaft of the driving motor is connected to the lead screw, and the lead screw is threadedly connected to the pushing block. Through the above arrangement, the driving shaft of the driving motor drives the lead screw to rotate, and the pushing block threadedly connected to the lead screw moves along the extension direction of the lead screw. The first inclined surface moves in a direction parallel to the structure, so that the second inclined surface slides relative to the first inclined surface, and further enables the heat dissipation housing to rotate relative to the structural member, increasing the air volume between the heat dissipation housing and the structural member, which is beneficial to improving the heat dissipation efficiency of the electronic device.

[0058] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0059] Hereinafter, terms such as "first" and "second" are only used for convenience of description and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more such features. In the description of this application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0060] In the embodiments of this application, words such as "exemplary" or "for example" are used to mean serving as an example, illustration, or explanation. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0061] In the embodiments of this application, direction indicators such as up, down, left, right, front, and back used to explain the structures and movement directions of different components in this application are relative. When the components are in the positions shown in the figure, these indicators are appropriate. However, if the description of the component positions changes, then these direction indicators will also change accordingly.

[0062] The embodiments of this application provide an electronic device. Among them, the electronic device can be a terminal product such as a mobile phone, a pad, a television, a smart wearable product (for example, a smart watch, a smart bracelet), a virtual reality (VR) device, an augmented reality (AR) device, etc.

[0063] Figure 1 It is a structural diagram of an electronic device provided by the embodiments of this application in a closed state; Figure 2 It is a structural diagram of an electronic device provided by the embodiments of this application in an open state; Figure 3 It is an exploded view of the structure of an electronic device provided by the embodiments of this application. Hereinafter, reference is made to Figure 1 、 Figure 2 and Figure 3 to describe the electronic device in the embodiments of this application.

[0064] The electronic device 1 may further include a housing 90 and a display module 80, and the display module 80 is connected to the housing 90. Among them, the display module 80 may include a display panel, and the display panel may adopt a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Miniled, a MicroLed, a Micro-oLed, a quantum dot light-emitting diode (QLED), etc.

[0065] Among them, the housing 90 may include a structural member 93, and the structural member 93 may be connected to the display module 80. The structural member 93 may include, for example, a middle frame structure for mounting and fixing other functional components in the electronic device 1.

[0066] In some embodiments, the electronic device 1 includes a plurality of functional components (not shown in the figure), and the plurality of functional components may be mounted on the structural member 93. The plurality of functional components may include, for example, a camera module, a processor, an internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, a headphone interface, a sensor module, a key, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc. Among them, the electronic device 1 may have more or fewer components than those described above, may combine two or more components, or may have different component configurations. The various components may be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and / or application-specific integrated circuits.

[0067] Continuing to refer to Figure 3 , the housing 90 may further include a support housing 92 and a lifting mechanism 10. The support housing 92 may be rotatably connected to the structural member 93, and the support housing 92 may be located on the side of the structural member 93 away from the display module 80. The lifting mechanism 10 may be fixedly connected to the structural member 93, and the lifting mechanism 10 may also be connected to the support housing 92. The lifting mechanism 10 is used to drive the support housing 92 to rotate relative to the structural member 93.

[0068] Among them, asFigure 1 As shown, when the lifting mechanism 10 is in the closed state, the support housing 92 is closed relative to the structural member 93 through the lifting mechanism 10. For example, the support housing 92 and the structural member 93 are parallel to each other. The support housing 92 is used to protect the devices inside the middle frame structure and also to present part of the appearance of the foldable electronic device 1.

[0069] As Figure 2 shown, when the lifting mechanism 10 is in the open state, the support housing 92 is opened relative to the structural member 93 through the lifting mechanism 10, and the support housing 92 is used to support the structural member 93. For example, the included angle between the support housing 92 and the structural member 93 is a1 (a1 can be, for example, 30°, 60° or 130°). For example, the support housing 92 is used for the user to apply a force and plays a supporting role for the structural member 93. The lifting mechanism 10 is used to realize the rotation of the support housing 92 and provide torsion to hold the support housing 92 at a certain opening and closing angle.

[0070] In addition, referring to Figure 1 and Figure 3 , the housing 90 may further include an inner housing 94. The inner housing 94 is located between the support housing 92 and the structural member 93, and the lifting mechanism is located between the inner housing 94 and the structural member 93. When the support housing 92 is opened relative to the structural member 93, the inner housing 94 can be used to shield the structural member 93 and the lifting mechanism 10, which is beneficial to improving the aesthetics.

[0071] In one embodiment, the electronic device 1 includes but is not limited to a two-in-one product, an all-in-one computer, and a mobile phone. Among them, the two-in-one product usually includes a host and a keyboard assembly. The host and the keyboard assembly are detachably connected. After the host is separated from the keyboard assembly, the host can still be used as an independent electronic device 1. For example, the host can be a tablet computer. Among them, the host may include the structural member 93 in the electronic device 1, the display module 80 fixed to the structural member 93, and functional components. The support housing 92 may be located on the back side of the host to support the host, and the rotating shaft device is located between the host and the support member.

[0072] Based on the above structure, in some embodiments, heat dissipation holes may also be provided on the structural member 93. For example, the heat dissipation holes may be located on the side or the top of the structural member 93. However, setting a plurality of heat dissipation holes on the structural member 93 easily causes an increase in the thickness of the structural member 93, and further causes an increase in the thickness of the electronic device 1. Moreover, setting a plurality of heat dissipation holes on the structural member 93 also affects the aesthetics of the electronic device 1.

[0073] Figure 4 This is a structural diagram of a heat dissipation housing provided by an embodiment of the present application. Combining Figure 4, in view of this, the housing 90 may further include a heat dissipation housing 91. The heat dissipation housing 91 may be rotatably connected to the structural member 93, and the heat dissipation housing 91 and the support housing 92 are located on the same side of the structural member 93. The display module 80 is located on the side of the structural member 93 away from the support housing 92 and the heat dissipation housing 91. Accordingly, at least a part of the lifting mechanism 10 provided in the embodiment of the present application may be connected between the heat dissipation housing 91 and the structural member 93. The lifting mechanism 10 has a closed state and an open state, and the lifting mechanism 10 is used to drive the heat dissipation housing 91 to rotate relative to the structural member 93.

[0074] As Figure 1 shown, when the lifting mechanism 10 is in the closed state, the support housing 92 is closed relative to the structural member 93 through the lifting mechanism 10, and the heat dissipation housing 91 is closed relative to the structural member 93 through the lifting mechanism 10. For example, the heat dissipation housing 91 and the structural member 93 are parallel to each other. Through the above settings, when the electronic device 1 is not in use, the lifting mechanism 10 is in the closed state, and both the support housing 92 and the heat dissipation housing 91 are also closed relative to the structural member 93, which is beneficial to saving occupied space.

[0075] As Figure 2 shown, when the lifting mechanism 10 is in the open state, the support housing 92 is opened relative to the structural member 93 through the lifting mechanism 10, and the support housing 92 is used to support the structural member 93. The heat dissipation housing 91 is opened relative to the structural member 93 through the lifting mechanism 10, and the heat dissipation housing 91 exposes the heat dissipation holes 915 communicating with the external environment. For example, the included angle between the heat dissipation housing 91 and the structural member 93 is a2 (a2 may be 5°, 8° or 10° for example). Through the above settings, when the user uses the electronic device 1, the lifting mechanism 10 is in the open state, and the support housing 92 is opened relative to the structural member 93, which is beneficial to supporting the electronic device 1 and meeting the user's usage requirements in different scenarios; at the same time, the heat dissipation housing 91 is opened relative to the structural member 93, and the heat dissipation housing 91 exposes the heat dissipation holes 915 communicating with the external environment, which is beneficial to realizing the heat dissipation of the electronic device 1. Compared with directly providing the heat dissipation holes 915 on the structural member 93, it is beneficial to reduce the thickness of the electronic device 1.

[0076] In some embodiments, with continued reference to Figure 4 , the heat dissipation housing 91 may include a cover plate 911 and a side plate 913. The side plate 913 is disposed around the edge of the cover plate 911, and the side plate 913 is located on the side of the cover plate 911 facing the structural member 93. The side plate 913 has through heat dissipation holes 915. For example, the cover plate 911 may be a rectangular flat plate, and the side plate 913 may extend along the edge of the cover plate 911 in a direction perpendicular to the cover plate 911. Accordingly, as shown in Figure 3 , the structural member 93 may have a receiving groove 931, and the receiving groove 931 may be located on the side of the structural member 93 facing the heat dissipation housing 91.

[0077] When the lifting mechanism 10 is in the closed state, the heat dissipation holes 915 can be located within the orthographic projection of the structural member 93 on the side plate 913. For example, when the lifting mechanism 10 is in the closed state, the cover plate 911 of the heat dissipation housing 91 can be parallel to the bottom of the accommodation groove 931, and the side plate 913 of the heat dissipation housing 91 can be located within the accommodation groove 931, so that the heat dissipation holes 915 can be located within the orthographic projection of the groove wall of the accommodation groove 931 on the side plate 913. Through the above arrangement, the structural member 93 shields the heat dissipation holes 915 on the side plate 913, which is beneficial to reducing the thickness of the electronic device 1 when the electronic device 1 does not need heat dissipation.

[0078] When the lifting mechanism 10 is in the open state, at least part of the heat dissipation holes 915 are located outside the orthographic projection of the structural member 93 on the side plate 913. For example, when the lifting mechanism 10 is in the open state, there can be an included angle between the plane where the cover plate 911 is located and the plane where the bottom of the accommodation groove 931 is located, and at least part of the heat dissipation holes 915 can be located outside the accommodation groove 931, so that at least part of the heat dissipation holes 915 can be located outside the orthographic projection of the groove wall of the accommodation groove 931 on the side plate 913. Through the above arrangement, the heat dissipation holes 915 on the side plate 913 are exposed, which is beneficial to improving the heat dissipation efficiency of the electronic device 1 when the electronic device 1 needs heat dissipation.

[0079] Figure 5 It is a structural diagram of a lifting mechanism in the closed state provided by an embodiment of the present application; Figure 6 It is a structural diagram of a lifting mechanism in the open state provided by an embodiment of the present application; Figure 7 It is another structural diagram of a lifting mechanism in the open state provided by an embodiment of the present application; Figure 8 It is an exploded view of the structure of a lifting mechanism provided by an embodiment of the present application. The following will be combined with Figure 5 , Figure 6 , Figure 7 and Figure 8 to illustrate a lifting mechanism provided by an embodiment of the present application.

[0080] In some embodiments, the lifting mechanism 10 may include a base 100, a flipping bracket 200, a lifting bracket 300, and a linkage assembly 400. Among them, the base 100 may include opposite first surface N1 and second surface N2, and the direction from the second surface N2 to the first surface N1 is the lifting direction Z. Exemplarily, the base 100 may include opposite bottom surface and top surface, the top surface may be the first surface N1, the bottom surface may be the second surface N2, the bottom surface may be in contact with the structural member 93, for example, the bottom surface may be in contact with the bottom of the accommodation groove 931 and parallel to the bottom of the accommodation groove 931. The top surface may be the surface away from the structural member 93.

[0081] In some embodiments, the flipping bracket 200 can be rotatably connected to the base 100. Among them, the flipping bracket 200 can include a first connection end 200a and a first free end 200b, and the first connection end 200a is rotatably connected to the base 100. The lifting bracket 300 can be movably connected to the base 100. Among them, the lifting bracket 300 can include a second connection end 300a and a second free end 300b, and the second connection end 300a is movably connected to the base 100. The linkage assembly 400 can connect the flipping bracket 200 and the lifting bracket 300.

[0082] Among them, the second surface N2 of the base 100 can be connected to the structural member 93, the first free end 200b of the flipping bracket 200 can be connected to the support housing 92, and the second free end 300b of the lifting bracket 300 can be connected to the heat dissipation housing 91. Through the above settings, when the flipping bracket 200 rotates relative to the base 100, the flipping bracket 200 can drive the support housing 92 to rotate relative to the structural member 93; when the lifting bracket 300 moves relative to the base 100, the lifting bracket 300 can drive the heat dissipation housing 91 to move relative to the structural member 93.

[0083] Referring to Figure 8 , the base 100 can include a first support member 100a and a second support member 100b, and the first support member 100a and the second support member 100b can enclose a frame. The base 100 can be connected to the structural member 93 together by threaded fasteners such as bolts.

[0084] The rotation axis of the flipping bracket 200 rotating relative to the base 100 can be the first axis L1. For the convenience of description below, the direction perpendicular to the first axis L1 and parallel to the second surface N2 can be defined as the first direction Y, and the direction parallel to the first axis L1 can be defined as the second direction X.

[0085] When the lifting mechanism 10 is in the closed state, in the lifting direction Z, the distance between the first free end 200b of the flipping bracket 200 and the second surface N2 is the first distance D1, and the distance between the second free end 300b of the lifting bracket 300 and the second surface N2 is the second distance D2. When the lifting mechanism 10 is in the open state, in the lifting direction Z, the distance between the first free end 200b of the flipping bracket 200 and the second surface N2 is the third distance D3, and the distance between the second free end 300b of the lifting bracket 300 and the second surface N2 is the fourth distance D4. The third distance D3 is greater than the first distance D1, and the fourth distance D4 is greater than the second distance D2.

[0086] With the above settings, when the lifting mechanism 10 is in the closed state, the flipping bracket 200 drives the support housing 92 to close relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation housing 91 to close relative to the structural member 93, so that the electronic device 1 is in the closed state. When the lifting mechanism 10 is in the open state, the flipping bracket 200 drives the support housing 92 to open relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation housing 91 to open relative to the structural member 93, so that the electronic device 1 is in the open state.

[0087] During the process of the lifting mechanism 10 transitioning from the closed state to the open state, the flipping bracket 200 rotates towards the lifting direction Z, and the flipping bracket 200 drives the lifting bracket 300 to move in the lifting direction Z through the linkage assembly 400. For example, during the process of the lifting mechanism 10 transitioning from the closed state to the open state, the first free end 200b of the flipping bracket 200 can rotate towards the lifting direction Z. The lifting bracket 300 can be connected to the flipping bracket 200 through the linkage assembly 400. When the flipping bracket 200 moves, the linkage assembly 400 drives the lifting bracket 300 to move. For example, during the process of the lifting mechanism 10 transitioning from the closed state to the open state, the flipping bracket 200 drives the second free end 300b of the lifting bracket 300 to move in the lifting direction Z through the linkage assembly 400.

[0088] In summary, when the lifting mechanism 10 is in the closed state, the flipping bracket 200 drives the support housing 92 to close relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation housing 91 to close relative to the structural member 93. This is beneficial for saving the occupied space of the electronic device 1 and reducing the thickness of the electronic device 1 when the electronic device 1 is in the closed state. When the lifting mechanism 10 is in the open state, the flipping bracket 200 drives the support housing 92 to open relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation housing 91 to open relative to the structural member 93. This is beneficial for the support housing 92 to support the electronic device 1. At the same time, it increases the air volume between the heat dissipation housing 91 and the structural member 93, which is beneficial for improving the heat dissipation efficiency of the electronic device 1.

[0089] In some embodiments, the lifting mechanism 10 can be rotatably connected to the base 100. For example, the second connection end 300a of the lifting mechanism 10 can be rotatably connected to the base 100, and the second free end 300b of the lifting mechanism 10 can rotate relative to the base 100, thereby changing the distance between the second free end 300b of the lifting mechanism 10 and the second surface N2 in the lifting direction Z. Alternatively, in some other embodiments, the lifting mechanism 10 can also be drivingly connected to the base 100. For example, the base 100 can drive the second connection end 300a of the lifting mechanism 10 to move, thereby changing the distance between the second free end 300b of the lifting mechanism 10 and the second surface N2 in the lifting direction Z.

[0090] Figure 9 An assembly structure diagram of a flipping bracket and a transition slider provided by an embodiment of the present application. Among them, Figure 9 Figure (a) in Figure 9 is a structure diagram of the flipping bracket and the transition slider in a relative rotation state; Figure 10 is an exploded structure diagram of a flipping bracket and a transition slider provided by an embodiment of the present application. Referring to Figure 8 、 Figure 9 and Figure 10 , the base 100 may have a first arc-shaped chute 110, and the first connection end 200a of the flipping bracket 200 may have a first arc-shaped slider 220, and the first arc-shaped slider 220 may be slidably connected to the first arc-shaped chute 110. Exemplarily, the base 100 may include two first arc-shaped chutes 110, and the two first arc-shaped chutes 110 are respectively denoted as a first sub-chute 110a and a second sub-chute 110b.

[0091] Figure 11 is a structure diagram of a base provided by an embodiment of the present application. Referring to Figure 11 , the first support member 100a and the second support member 100b may be arranged along the second direction X. The first support member 100a may include a first extension portion 101a extending along the first direction Y, and the second support member 100b may include a second extension portion 101b extending along the first direction Y. The side of the first extension portion 101a facing the second extension portion 101b may have a first sub-chute 110a, and the side of the second extension portion 101b facing the first extension portion 101a may have a second sub-chute 110b.

[0092] Correspondingly, referring to Figure 10 , the flipping bracket 200 may include a first main body 210 and two first arc-shaped sliders 220. The first main body 210 is used to connect to the support housing 92. The two first arc-shaped sliders 220 are respectively denoted as a first sub-slider 220a and a second sub-slider 220b. For example, the first sub-slider 220a and the second sub-slider 220b are respectively connected to the first main body 210 and are arranged along the second direction X. The first sub-slider 220a is slidably connected to the first sub-chute 110a, and the second sub-slider 220b is slidably connected to the first sub-chute 110a.

[0093] With the above settings, the base 100 and the flipping bracket 200 can be rotationally connected together by a rotational connection manner of a virtual axis. When the first arc-shaped slider 220 of the flipping bracket 200 slides in the first arc-shaped chute 110, the flipping bracket 200 rotates relative to the base 100. Among them, the center line of the first arc-shaped slider 220 coincides with the center line of the first arc-shaped chute 110, and moreover, the center line of the first arc-shaped slider 220 is the first axis L1, and the center line of the first arc-shaped chute 110 is also the first axis L1. Among them, the first axis L1 can be a virtual axis, and the first axis L1 can be located on the side of the base 100 close to the first surface N1.

[0094] Of course, in some other embodiments, the base 100 can have the first arc-shaped slider 220, the first connection end 200a of the flipping bracket 200 can have the first arc-shaped chute 110, and the first arc-shaped slider 220 can be slidably connected to the first arc-shaped chute 110, so that the base 100 and the flipping bracket 200 can be rotationally connected together by a rotational connection manner of a virtual axis.

[0095] Continue to refer to Figure 8 、 Figure 9 and Figure 10 In addition, the lifting mechanism 10 can further include a transition slider 500. The first end of the transition slider 500 is rotationally connected to the base 100, the second end of the transition slider 500 is rotationally connected to the flipping bracket 200, the rotational axis between the transition slider 500 and the base 100 is the first axis L1, and the rotational axis between the transition slider 500 and the lifting bracket 300 is the first axis L1.

[0096] Exemplarily, the lifting mechanism 10 can include two transition sliders 500, which are respectively denoted as the first transition slider 500a and the second transition slider 500b. Among them, the first transition slider 500a can be connected between the base 100 and the flipping bracket 200, and the second transition slider 500b can be connected between the base 100 and the flipping bracket 200. With the above settings, the first arc-shaped slider 220 of the flipping bracket 200 rotates relative to the transition slider 500, and the transition slider 500 rotates relative to the first arc-shaped chute 110 of the base 100, which is beneficial to increasing the rotation angle of the flipping bracket 200 relative to the base 100 and is beneficial to meeting the usage requirements of users in different scenarios.

[0097] In some embodiments, such as Figure 6 and Figure 7As shown, a support area S can be formed between the flip bracket 200 and the base 100. Within the support area S and in a direction perpendicular to the first axis L1, the flip bracket 200 shields the transition slider 500. Here, the "support area S" can be understood as a fan-shaped area sandwiched between the flip bracket 200 and the base 100, and the support area S is exposed to the user's view. Here, "shield" can be understood as that within the support area S and from a perspective perpendicular to the first axis L1, the flip bracket 200 covers the transition slider 500 so that the transition slider 500 is not exposed to the user's view.

[0098] It can be understood that during the rotation of the flip bracket 200 relative to the base 100, the rotational movement position of the transition slider 500 relative to the base 100 is not fixed, that is, the rotation angle of the transition slider 500 relative to the base 100 is not fixed. To achieve a good support effect for the support housing 92, multiple lifting mechanisms 10 are usually included in the electronic device 1. Through the above settings, since the flip bracket 200 covers the transition slider 500, it is avoided that the user observes the phenomenon that the rotation angles of the transition sliders 500 in the multiple lifting mechanisms 10 are out of sync, which is beneficial to improving the aesthetics of the lifting mechanism 10.

[0099] Continue to refer to Figure 9 and Figure 10 Figure, the flip bracket 200 can also have a second arc-shaped chute 230. The second arc-shaped chute 230 is adjacent to the first arc-shaped slider 220. The second end of the transition slider 500 has a second arc-shaped slider 521, and the second arc-shaped slider 521 is slidably connected to the second arc-shaped chute 230.

[0100] Exemplarily, the flip bracket 200 can also include two second arc-shaped chutes 230. Denote the two second arc-shaped chutes 230 as the third sub-chute 230a and the fourth sub-chute 230b. Among them, the third sub-chute 230a is adjacent to the first sub-slider 220a, and the third sub-chute 230a is closer to the first axis L1 than the first sub-slider 220a; the fourth sub-chute 230b is adjacent to the second sub-slider 220b, and the fourth sub-chute 230b is closer to the first axis L1 than the second sub-slider 220b.

[0101] Correspondingly, denote the two second arc-shaped sliders 521 as the third sub-slider 521a and the fourth sub-slider 521b. The second end of the first transition slider 500a can have a third sub-slider 521a, and the third sub-slider 521a is slidably connected to the third sub-chute 230a; the second end of the second transition slider 500b can have a fourth sub-slider 521b, and the fourth sub-slider 521b is slidably connected to the fourth sub-chute 230b.

[0102] With the above settings, the flipping bracket 200 and the transition slider 500 can be rotationally connected together by means of a virtual axis. When the second end of the transition slider 500 slides within the second arc-shaped chute 230, the flipping bracket 200 rotates relative to the transition slider 500. Among them, the center line of the second arc-shaped slider 521 coincides with the center line of the second arc-shaped chute 230, and the center line of the second arc-shaped slider 521 is also the first axis L1, and the center line of the second arc-shaped chute 230 is also the first axis L1, so that the rotation axis of the flipping bracket 200 relative to the transition slider 500 is the first axis L1.

[0103] Alternatively, in some other embodiments, the flipping bracket 200 may further have a second arc-shaped slider 521, the second end of the transition slider 500 has a second arc-shaped chute 230, and the second arc-shaped slider 521 is slidably connected to the second arc-shaped chute 230, so that the flipping bracket 200 and the transition slider 500 can be rotationally connected together by means of a virtual axis.

[0104] Based on the above structure, continue to refer to Figure 10 , a part of the groove wall of the second arc-shaped chute 230 protrudes to form a first stop block 250. Correspondingly, the second arc-shaped slider 521 further has a second stop block 5213 that cooperates with the first stop block 250. When the flipping bracket 200 rotates relative to the transition slider 500 to a certain angle, the first stop block 250 and the second stop block 5213 abut against each other, so that the flipping bracket 200 stops rotating relative to the transition slider 500, which is beneficial to preventing the flipping bracket 200 from detaching from the transition slider 500 during the rotation process, and thus is beneficial to improving the rotational reliability between the flipping bracket 200 and the transition slider 500.

[0105] Continue to refer to Figure 8 and Figure 10 , the base 100 further has a third arc-shaped slider 120, the third arc-shaped slider 120 is adjacent to the first arc-shaped chute 110, the first end of the transition slider 500 has a third arc-shaped chute 511 and a fourth arc-shaped slider 512, the third arc-shaped chute 511 is adjacent to the fourth arc-shaped slider 512, the third arc-shaped slider 120 is slidably connected to the third arc-shaped chute 511, and the fourth arc-shaped slider 512 and the first arc-shaped slider 220 are jointly slidably connected to the first arc-shaped chute 110.

[0106] Exemplarily, the base 100 may further include two third arc-shaped sliders 120, which are denoted as a fifth sub-slider 120a and a sixth sub-slider 120b. Among them, the fifth sub-slider 120a is adjacent to the first sub-chute 110a, and the fifth sub-slider 120a is closer to the first axis L1 than the first sub-chute 110a; the sixth sub-slider 120b is adjacent to the second sub-chute 110b, and the sixth sub-chute 511b is closer to the first axis L1 than the second sub-slider 220b.

[0107] Correspondingly, the two third arc-shaped chutes 511 are denoted as a fifth sub-chute 511a and a sixth sub-chute 511b, the two fourth arc-shaped sliders 512 are denoted as a seventh sub-slider 512a and an eighth sub-slider 512b. The first end of the first transition slider 500a may have an adjacent fifth sub-chute 511a and seventh sub-slider 512a, and the seventh sub-slider 512a is farther from the first axis L1 than the fifth sub-chute 511a. The seventh sub-slider 512a is slidably connected to the first sub-slider 220a and the first sub-chute 110a, and the fifth sub-slider 120a is within the fifth sub-chute 511a. The first end of the second transition slider 500b may have an adjacent sixth sub-chute 511b and eighth sub-slider 512b, and the eighth sub-slider 512b is farther from the first axis L1 than the sixth sub-chute 511b. The eighth sub-slider 512b is slidably connected to the second sub-slider 220b and the second sub-chute 110b, and the sixth sub-slider 120b is slidably connected to the sixth sub-chute 511b.

[0108] Through the above settings, the base 100 and the transition slider 500 can be rotationally connected together by a rotational connection method of a virtual axis. When the third arc-shaped slider 120 slides within the first end of the transition slider 500, the transition slider 500 rotates relative to the base 100. Among them, the center line of the third arc-shaped slider 120 coincides with the center line of the third arc-shaped chute 511, and moreover, the center line of the third arc-shaped slider 120 is the first axis L1, and the center line of the third arc-shaped chute 511 is also the first axis L1, so that the rotation axis of the transition slider 500 relative to the base 100 is the first axis L1.

[0109] Alternatively, in some other embodiments, the base 100 further has a third arc-shaped chute 511, and the first end of the transition slider 500 has a third arc-shaped slider 120, and the third arc-shaped slider 120 is slidably connected to the third arc-shaped chute 511, so that the base 100 and the transition slider 500 can be rotationally connected together by a rotational connection method of a virtual axis.

[0110] Based on the above structure, the first end of the first transition slider 500a can protrude to form a third stop block 513. Correspondingly, the third arc-shaped slider 120 also has a fourth stop block 130 that cooperates with the third stop block 513. When the transition slider 500 rotates relative to the base 100 by a certain angle, the third stop block 513 and the fourth stop block 130 abut against each other, so that the transition slider 500 stops rotating relative to the base 100, which helps to prevent the transition slider 500 from detaching from the base 100 during the rotation process, and thus helps to improve the rotational reliability between the transition slider 500 and the base 100.

[0111] In the direction parallel to the first axis L1, the first end of the transition slider 500 is flush with the first arc-shaped slider 220, or the first arc-shaped slider 220 extends beyond the first end of the transition slider 500.

[0112] Exemplarily, in the direction parallel to the first axis L1, the fourth arc-shaped slider 512 and the third stop block 513 of the transition slider 500 can both be flush with the first arc-shaped slider 220, or the first arc-shaped slider 220 extends beyond the fourth arc-shaped slider 512 and the third stop block 513 of the transition slider 500. With the above arrangement, within the support area S, when viewed from a perspective perpendicular to the first axis L1 (e.g., Figure 6 and Figure 7 the P perspective in

[0113] Based on the above structure, referring to Figure 10 , the second arc-shaped chute 230 can include a first arc-shaped surface 231 and a second arc-shaped surface 232. The first arc-shaped surface 231 is farther from the first axis L1 than the second arc-shaped surface 232, and the first arc-shaped surface 231 is adjacent to the first arc-shaped slider 220. A part of the first arc-shaped surface 231 is recessed in the direction away from the first axis L1 to form an arc-shaped mating chute 240. Correspondingly, the transition slider 500 has an arc-shaped slide rail 530. The arc-shaped slide rail 530 is arranged along the circumference of the transition slider 500, and the arc-shaped slide rail 530 is slidably connected to the arc-shaped mating chute 240.

[0114] Exemplarily, the center line of the arc-shaped mating chute 240 can be the first axis L1, and the center line of the arc-shaped slide rail 530 can also be the first axis L1. With the above arrangement, when the flip bracket 200 rotates relative to the transition slider 500, it is possible to prevent the transition slider 500 from deflecting due to a lateral force, which helps to improve the rotational reliability between the flip bracket 200 and the transition slider 500.

[0115] In some embodiments, the lifting bracket 300 may be rotatably connected to the base 100. The rotation axis of the lifting bracket 300 relative to the base 100 is the second axis L2, and the second axis L2 is parallel to the first axis L1.

[0116] Continuing to refer to Figure 8 , the lifting bracket 300 may include two lifting members arranged along the second direction X. Denote the two lifting members as the first lifting member 300c and the second lifting member 300d. Wherein, the base 100 may further include two protruding posts 150 arranged oppositely along the second direction X. One of the protruding posts 150 is located on the side of the first extension portion 101a of the first support member 100a away from the second support member 100b, and the other protruding post 150 is located on the side of the second extension portion 101b of the second support member 100b away from the first support member 100a. One end of the first lifting member 300c may be sleeved on the protruding post 150 of the first support member 100a to rotatably connect the first lifting member 300c to the first support member 100a; one end of the second lifting member 300d may be sleeved on the protruding post 150 of the second support member 100b to rotatably connect the second lifting member 300d to the second support member 100b.

[0117] With the above arrangement, one end of the lifting bracket 300 is rotatably connected to the base 100, and the other end of the lifting bracket 300 can be connected to the heat dissipation housing 91. The other end of the lifting bracket 300 moves relative to the base 100 under the drive of the linkage assembly 400, so that the other end of the lifting bracket 300 drives the heat dissipation housing 91 to open or close relative to the base 100. At the same time, since the second axis L2 is parallel to the first axis L1, the rotation axis of the support housing 92 relative to the base 100 is parallel to the rotation axis of the heat dissipation housing 91 relative to the base 100, which is beneficial to improving the structural compactness of the lifting mechanism 10.

[0118] In addition, the lifting mechanism 10 may further include two spring buckles 600. One spring buckle 600 may be sleeved on a rotating shaft and is located on the side of the lifting bracket 300 away from the base 100. With the above arrangement, the lifting bracket 300 is prevented from disengaging from the base 100 during rotation.

[0119] In some embodiments, the orthographic projection of the second axis L2 on the reference plane and the orthographic projection of the first axis L1 on the reference plane may coincide, and the reference plane may be parallel to the second surface N2. Through the above arrangement, it is beneficial to improve the structural compactness of the lifting mechanism 10. Further, the second axis L2 may be located between the second free end 300b of the lifting bracket 300 and the first free end 200b of the flipping bracket 200. Through the above arrangement, the rotation direction of the support housing 92 relative to the base 100 is opposite to the rotation direction of the heat dissipation housing 91 relative to the base 100, so as to avoid interference between the support housing 92 and the heat dissipation housing 91 when the electronic device 1 is switched from the closed state to the open state.

[0120] Figure 12 Exploded view of the structure of another lifting mechanism provided by the embodiments of the present application. In combination with Figure 8 and Figure 12 , in some embodiments, the lifting bracket 300 may include a lifting chute 310. In the direction close to the second axis L2, the lifting chute 310 has an inclined chute section 311 that inclines in the direction close to the second surface N2. Exemplarily, the inclined chute section 311 may be strip-shaped, and in the direction close to the second axis L2, the extending direction of the length of the inclined chute section 311 may incline in the direction close to the second surface N2. Among them, one side of the first lifting member 300c facing the second lifting member 300d may have a lifting chute 310, and one side of the second lifting member 300d facing the first lifting member 300c may also have a lifting chute 310.

[0121] Correspondingly, the first end 400a of the linkage assembly may be fixedly connected to the flipping bracket 200, the second end 400b of the linkage assembly may be slidably connected to the lifting chute 310, and the linkage assembly 400 is also slidably connected to the base 100 in the first direction Y, and the first direction Y is parallel to the second surface N2 and perpendicular to the second axis L2. Since the flipping bracket 200 is rotatably connected to the base 100 by a virtual axis connection method, when the flipping bracket 200 rotates relative to the base 100, the flipping bracket 200 also moves relative to the base 100. Exemplarily, when the flipping bracket 200 rotates in the lifting direction Z (the rotation direction may be the Figure 12 clockwise direction B1 shown in Figure 12 ), the flipping bracket 200 also drives the linkage assembly 400 to move (the moving direction may be the Figure 12 translation direction B2 shown in

[0122] In summary, through the above settings, the linkage between the flipping bracket 200 and the lifting bracket 300 can be achieved. When the electronic device 1 is in the open state, the flipping bracket 200 drives the support housing 92 to open relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation housing 91 to open relative to the structural member 93. While the support housing 92 can support the electronic device 1, the heat dissipation housing 91 can also improve the heat dissipation efficiency of the electronic device 1.

[0123] In some embodiments, the lifting bracket 300 may further include a first smooth groove section 313 and a second smooth groove section 312. The inclined groove section 311 communicates between the first smooth groove section 313 and the second smooth groove section 312, and the first smooth groove section 313 is farther from the second axis L2 than the second smooth groove section 312.

[0124] When the lifting mechanism 10 is in the closed state, the second end 400b of the linkage assembly is located in the first smooth groove section 313, and the first smooth groove section 313 extends along the first direction Y. Through the above settings, when the flipping bracket 200 is in the closed state relative to the base 100, since the first smooth groove section 313 extends along the first direction Y and the second end 400b of the linkage assembly is located in the first smooth groove section 313, the lifting bracket 300 is also in the closed state relative to the base 100.

[0125] When the lifting mechanism 10 is in the open state, the second end 400b of the linkage assembly is located in the inclined groove section 311 and the second smooth groove section 312, and the second smooth groove section 312 extends along the first direction Y. During the process of the lifting mechanism 10 transitioning from the closed state to the open state, the second end 400b of the linkage assembly slides from the first smooth groove section 313, via the inclined groove section 311, to the second smooth groove section 312. Through the above settings, when the flipping bracket 200 rotates relative to the base 100, since the second end 400b of the linkage assembly slides in the inclined groove section 311, the lifting bracket 300 is driven to rotate relative to the base 100, so that the lifting bracket 300 is also in the open state relative to the base 100. When the flipping bracket 200 rotates relative to the base 100 by a certain angle, the second end 400b of the linkage assembly slides from the inclined groove section 311 to the second smooth groove section 312. At this time, since the second smooth groove section 312 extends along the first direction Y, when the flipping bracket 200 continues to rotate relative to the base 100, the rotation angle of the lifting bracket 300 relative to the base 100 remains unchanged, and the open state of the lifting bracket 300 relative to the base 100 does not change.

[0126] Wherein, the lengths of the first smooth groove section 313 and the second smooth groove section 312 can be set according to actual requirements, and the embodiments of the present application do not make special limitations on this.

[0127] Figure 13An assembly structure diagram of a base, a flip bracket, and a linkage assembly provided by an embodiment of the present application; Figure 14 is Figure 13 the structural explosion diagram of the assembly structure in Figure 15 An embodiment of the present application provides a structural explosion diagram of a flip bracket and a linkage assembly. The following will be combined with Figure 13 , Figure 14 and Figure 15 to illustrate the linkage assembly in the embodiments of the present application.

[0128] In some embodiments, the linkage assembly 400 may include a first shaft core 410, a first connecting rod 420, and a second connecting rod 440. Among them, the first shaft core 410 may be connected to the flip bracket 200, the first connecting rod 420 may be connected between the first shaft core 410 and the second connecting rod 440, and the second connecting rod 440 may be connected to the lifting bracket 300. Through the above settings, the lifting bracket 300 can be connected to the flip bracket 200 through the linkage assembly 400.

[0129] Referring to Figure 15 , the first shaft core 410 may be fixedly connected to the flip bracket 200, and the axial direction of the first shaft core 410 is parallel to the first axis L1. The first end 421 of the first connecting rod is sleeved on the first shaft core 410 and is rotatably connected to the first shaft core 410, and the first end 421 of the first connecting rod has a clearance fit with the first shaft core 410. The second connecting rod 440 is slidably connected to the base 100 along the first direction Y. The first end 441 of the second connecting rod is rotatably connected to the second end 422 of the first connecting rod. The second end 442 of the second connecting rod is located on the side of the first connecting rod 420 away from the first shaft core 410, and the second end 442 of the second connecting rod is slidably connected to the lifting chute 310.

[0130] Exemplarily, the flip bracket 200 may include two fixing holes 550 arranged along the second direction X. The fixing holes 550 are located on the side of the flip bracket 200 away from the first arc-shaped slider 220. Both ends of the first shaft core 410 may be inserted into the two fixing holes 550 and have an interference fit with the fixing holes 550 to fixedly connect the first shaft core 410 to the flip bracket 200. The first end 421 of the first connecting rod may have a first connection hole 4213 penetrating along the second direction X. The first connection hole 4213 has a clearance fit with the first shaft core 410 to enable the first end 421 of the first connecting rod to be rotatably connected to the first shaft core 410.

[0131] In addition, the linkage assembly 400 may further include a second shaft core 430. The axial direction of the second shaft core 430 may be parallel to the first axis L1. The second end 422 of the first link is sleeved on the second shaft core 430 and rotatably connected to the second shaft core 430. The first end 441 of the second link is sleeved on the second shaft core 430 and rotatably connected to the second shaft core 430. Exemplarily, the second end 422 of the first link may have a second connection hole 4215 penetrating along the second direction X. The second connection hole 4215 is in clearance fit with the second shaft core 430 to enable the second end 422 of the first link to be rotatably connected to the second shaft core 430. The first end 441 of the second link may have a third connection hole 4413 penetrating along the second direction X. The third connection hole 4413 is in clearance fit with the second shaft core 430 to enable the first end 441 of the second link to be rotatably connected to the third shaft core. The second end 442 of the second link may have a first guide post 4415 protruding in the second direction X. The first guide post 4415 may be slidably engaged with the lifting chute 310 to enable the second end 442 of the second link to be slidably connected to the lifting chute 310.

[0132] In the embodiments of the present application, the numbers of the first link 420 and the second link 440 are not specifically limited. For example, as Figure 15 shown, the number of the first links 420 may be one, and the number of the second links 440 may be two. One of the second links 440 is slidably connected to the lifting chute 310 of the first lifting member 300c, and the other second link 440 is slidably connected to the lifting chute 310 of the second lifting member 300d.

[0133] Figure 16 For Figure 13 the sectional view of the assembly structure along the A-A section line in Figure 13 and Figure 16, the base 100 may have a sliding hole 160 extending through in the first direction Y. The sliding hole 160 is located on the side of the guiding groove 170 away from the first arc-shaped sliding groove 110. The second connecting rod 440 is slidably connected to the sliding hole 160, and the second end 442 of the second connecting rod is located on the side of the sliding hole 160 away from the lifting sliding groove 310. Exemplarily, the first support plate of the base 100 may include a first bending portion 101c extending in the second direction X, and the second support plate of the base 100 may include a second bending portion 101d extending in the second direction X. The first bending portion 101c and the second bending portion 101d are stacked to jointly enclose the sliding hole 160. Wherein, the number of the sliding holes 160 may be the same as the number of the second connecting rods 440. In an embodiment where the number of the second connecting rods 440 is two, the number of the sliding holes 160 enclosed by the first bending portion 101c and the second bending portion 101d may also be two. Through the above arrangement, the second connecting rod 440 can be slidably connected to the base 100 along the first direction Y.

[0134] In summary, when the flipping bracket 200 rotates towards the lifting direction Z (the rotation direction may be Figure 12 the clockwise direction shown in Figure 12 ), the flipping bracket 200 also drives the first shaft core 410 to move along the first direction Y (the moving direction may be towards

[0135] the left side direction shown in Figure 14 ). The first shaft core 410 drives the first connecting rod 420 to move along the first direction Y. At the same time, the first connecting rod 420 also rotates relative to the first shaft core 410. The first connecting rod 420 drives the second connecting rod 440 to move along the first direction Y, so that the second connecting rod 440 slides relative to the lifting sliding groove 310 of the lifting bracket 300. The lifting bracket 300 rotates towards the lifting direction Z under the drive of the second connecting rod 440.

[0136] Figure 17 is an assembly structure diagram of a flipping bracket, a bushing, a first shaft core and a first connecting rod provided by an embodiment of the present application; Figure 18 is an exploded view of the structure of another lifting mechanism provided by an embodiment of the present application. Refer toFigure 17 and Figure 18 , in some embodiments, the lifting mechanism 10 may further include a bushing 700. In combination with Figure 8 , the first end 710 of the bushing is sleeved on the first shaft core 410 and rotatably connected to the first shaft core 410. The first end 710 of the bushing is interference-fitted with the first shaft core 410, and the second end 720 of the bushing is slidably connected to the base 100 in a direction perpendicular to the first axis L1. Herein, "interference fit" refers to an interference fit or a fitting method that can generate torque and friction. Exemplarily, the first end 710 of the bushing may have a fitting hole 711 penetrating along the second direction X, and the fitting hole 711 is interference-fitted with the first shaft core 410 so that the first end 710 of the bushing is interference-fitted with the first shaft core 410. The second end 720 of the bushing may have two second guiding columns 721 protruding in the second direction X.

[0137] Correspondingly, the base 100 further includes a fitting chute 180. The extending direction of the fitting chute 180 may be perpendicular to the first axis L1, and in the direction approaching the first axis L1, the distance between the fitting chute 180 and the second surface N2 decreases. Among them, the number of the fitting chutes 180 may be two. One fitting chute 180 is located on the first extension 101a of the first support 100a, and the other fitting chute 180 is located on the second extension 101b of the second support 100b. The second guiding column 721 may be slidably fitted with the fitting chute 180 so that the second end 720 of the bushing is slidably connected to the fitting chute 180.

[0138] Through the above settings, during the rotation of the flipping bracket 200 relative to the base 100, the second end 720 of the bushing slides in the fitting chute 180. By setting the fitting chute 180 inclined relative to the second surface N2, it is beneficial to extend the length of the fitting chute 180 within a limited space, so as to increase the rotation angle of the flipping bracket 200 relative to the base 100. At the same time, the interference fit between the first end 710 of the bushing and the first shaft core 410 can provide torque, so that the flipping bracket 200 can maintain the required opening and closing angle when rotating relative to the base 100, and enables the support housing 92 to stably support the electronic device 1 and prevent the electronic device 1 from tipping over.

[0139] Figure 19 A structural diagram of a lifting mechanism provided by an embodiment of the present application after omitting a part of the lifting bracket and a part of the second link; Figure 20 A structural diagram of an elastic member provided by an embodiment of the present application. Refer to Figure 19 , in some embodiments, the lifting mechanism 10 may further include an elastic member 800. The first end 810 of the elastic member may be connected to the base 100, and the second end 820 of the elastic member may be connected to the lifting bracket 300. Exemplarily, in combination with Figure 14, one end of the first lifting member 300c away from the second axis 430 is bent towards the second lifting member 300d to form a first enclosing portion 301a, and one end of the second lifting member 300d away from the second axis 430 is bent towards the first lifting member 300c to form a second enclosing portion 301b. The first enclosing portion 301a and the second enclosing portion 301b are connected together and are located on the side of the first bending portion 101c and the second bending portion 101d away from the second axis L2. The first end 810 of the elastic member can be connected to the first bending portion 101c and / or the second bending portion 101d, and the second end of the elastic member 800 can be connected to the first enclosing portion 301a and / or the second enclosing portion 301b.

[0140] When the lifting mechanism 10 is in the closed state, the elastic member 800 is in the first state. When the lifting mechanism 10 is in the open state, the elastic member 800 is in the second state, and the deformation amount of the elastic member 800 in the second state is different from the deformation amount of the elastic member 800 in the first state. It can be understood that, in order to ensure the smooth movement between the sliding fit and the rotational fit in the above embodiments, the clearance fit is usually adopted between the shaft and the hole, and there is also usually a clearance between the chute and the slider. However, the superposition of multiple clearances may cause the lifting mechanism 10 to shake during movement. Through the above settings, when the deformation amount of the elastic member 800 of the lifting mechanism 10 is large, the elastic restoring force of the elastic member 800 is large. Under the action of the elastic restoring force of the elastic member 800 on the lifting mechanism 10, the lifting bracket 300 is pressed against the base 100 in a direction close to or away from the second surface N2, which is beneficial to reducing the fit clearance between the lifting bracket 300 and other structural members 93 and avoiding the shaking of the lifting mechanism 10 during movement.

[0141] For example, when the deformation amount of the elastic member 800 in the second state is greater than the deformation amount of the elastic member 800 in the first state, when the lifting mechanism 10 is in the open state, it is beneficial to reduce the fit clearance between the lifting bracket 300 and other structural members 93 and avoid the shaking of the lifting mechanism 10 during movement. Or, when the deformation amount of the elastic member 800 in the second state is less than the deformation amount of the elastic member 800 in the first state, when the lifting mechanism 10 is in the closed state, it is beneficial to reduce the fit clearance between the lifting bracket 300 and other structural members 93 and avoid the shaking of the lifting mechanism 10 during movement.

[0142] Figure 20 It is a structural diagram of an elastic member provided by an embodiment of the present application, where Figure 20 Figure (a) is a structural diagram of the elastic member 800 in the first state, Figure 20 Figure (b) is a structural diagram of the elastic member 800 in the second state. Combining Figure 20, in some embodiments, the elastic member 800 may include a first plate portion 811, a bent plate portion 830, and a second plate portion 821. The first plate portion 811 and the second plate portion 821 may both be parallel to the second surface N2. The bent plate portion 830 is connected between the first plate portion 811 and the second plate portion 821. The first plate portion 811 is connected to the base 100, and the second plate portion 821 is connected to the lifting bracket 300. The bent plate portion 830 bends in a direction close to or away from the second surface N2. When the lifting mechanism 10 is in the closed state, there is a first distance between the first plate portion 811 and the second plate portion 821. When the lifting mechanism 10 is in the open state, there is a second distance H2 between the first plate portion 811 and the second plate portion 821, and the second distance H2 is greater than the first distance.

[0143] Exemplarily, when the lifting mechanism 10 is in the closed state, the first plate portion 811 may be coplanar with the second plate portion 821. In the lifting direction Z, the first distance is zero. When the lifting mechanism 10 is in the open state, the second plate portion 821 is closer to the first surface N1 relative to the first plate portion 811. In the lifting direction Z, the second distance H2 is greater than the first distance. The elastic restoring force of the bent plate portion 830 acts on the lifting mechanism 10, so that the lifting bracket 300 is pressed against the base 100, which is beneficial to reducing the fitting clearance between the lifting bracket 300 and other structural members 93 and avoiding shaking when the lifting mechanism 10 moves.

[0144] In some other embodiments, the elastic member 800 may also be a torsion spring or a spring, etc., as long as it can achieve reducing the fitting clearance between the lifting bracket 300 and other structural members 93.

[0145] In some embodiments, the above-mentioned lifting mechanism 10 may be symmetrically arranged, or the above-mentioned lifting mechanism 10 may also be arranged unilaterally. For example, the base 100 may also include only one of the first support member 100a and the second support member 100b, and the lifting bracket 300 may also include only one of the first lifting member 300c and the second lifting member 300d. Correspondingly, the number of the second link 440 may also be only one.

[0146] Figure 21 It is an exploded view of the structure of another electronic device provided by the embodiment of the present application; Figure 22 It is an assembly structure diagram of a heat dissipation housing and a lifting mechanism provided by the embodiment of the present application. Refer to Figure 21 and Figure 22, in another housing 90 of the embodiment of the present application, the housing 90 includes a structural member 93 and a heat dissipation housing 91, wherein the heat dissipation housing 91 is rotatably connected to the structural member 93. Exemplarily, a connecting plate 101 may be connected to the structural member 93. The connecting plate 101 has a through hole, and the heat dissipation housing 91 may also have a matching through hole. A rotating shaft passes through the through hole of the connecting plate 101 and the through hole of the heat dissipation housing 91, so that the heat dissipation housing 91 and the structural member 93 are rotatably connected. The shapes of the heat dissipation housing 91 and the structural member 93 may be as described in the above embodiment, and will not be elaborated here.

[0147] Figure 23 is Figure 22 a partial enlarged view of the assembly structure in M in Figure 23 , the housing 90 further includes another lifting mechanism 10. The lifting mechanism 10 may be located between the structural member 93 and the heat dissipation housing 91. Among them, the lifting mechanism 10 may include a driving member 191 and a pushing block 192. The driving member 191 may be connected to the structural member 93, and the pushing block 192 may be connected to the driving member 191.

[0148] Figure 24 is Figure 22 a partial enlarged view of the heat dissipation housing in M in Figure 25 is a structural diagram of a first lifting mechanism provided by an embodiment of the present application. Referring to Figure 24 and Figure 25 , the pushing block 192 has a first inclined surface 1917, and one side of the heat dissipation housing 91 facing the structural member 93 has a second inclined surface 9133 that cooperates with the first inclined surface 1917. During the process of the lifting mechanism 10 switching between the closed state and the open state, the driving member 191 drives the pushing block 192 to move in a direction parallel to the structural member 93 (for example Figure 23 the C1 direction or the C2 direction in

[0149] In some embodiments, the driving member 191 can perform a linear reciprocating motion within a certain range. Since the driving member 191 is connected to the pushing block 192, the driving member 191 can drive the pushing block 192 to move in a direction parallel to the structural member 93. For example, the driving member 191 may be a cylinder, and the push rod of the cylinder is connected to the pushing block 192, and the push rod of the cylinder is parallel to the structural member 93.

[0150] Through the above settings, when the pushing block 192 moves in a direction parallel to the structural member 93 (for example Figure 23 the C1 direction in ), the first inclined surface 1917 moves in a direction parallel to the structure, so that the second inclined surface 9133 slides relative to the first inclined surface 1917, and further causes the heat dissipation housing 91 to open relative to the structural member 93, increasing the air volume between the heat dissipation housing 91 and the structural member 93, which is beneficial to improving the heat dissipation efficiency of the electronic device 1. When the pushing block 192 moves in a direction parallel to the structural member 93 and in the opposite direction (for exampleFigure 23 in the C2 direction, so that the heat dissipation housing 91 is closed relative to the structural member 93.

[0151] In some embodiments, referring to Figure 25 , the driving member 191 may include a driving motor and a lead screw 1913. The driving shaft of the driving motor is connected to the lead screw 1913, and the lead screw 1913 is threadedly connected to the push block 192. Based on the above structure, the driving shaft of the driving motor drives the lead screw 1913 to rotate. The lead screw 1913 may be arranged parallel to the structural member 93. The push block 192 threadedly connected to the lead screw 1913 moves along the extending direction of the lead screw 1913, and the first inclined surface 1917 moves in a direction parallel to the structure, so that the second inclined surface 9133 slides relative to the first inclined surface 1917, thereby causing the heat dissipation housing 91 to rotate relative to the structural member 93, increasing the air volume between the heat dissipation housing 91 and the structural member 93, and being beneficial to improving the heat dissipation efficiency of the electronic device 1.

[0152] In some embodiments, a circuit board 193 may further be included. The circuit board 193 is electrically connected to the driving motor. And the circuit board 193 may also be electrically connected to the main board of the electronic device 1. Among them, the main board of the electronic device 1 may include control software, and the driving motor is controlled to move through the control software.

[0153] In some embodiments, a data acquisition device may further be included. For example, the data acquisition device may include a temperature sensor, and the temperature sensor may be electrically connected to the main board of the electronic device 1. When the temperature of the electronic device 1 reaches a preset temperature, the main board of the electronic device 1 controls the driving motor to move, so that the heat dissipation housing 91 is opened relative to the structural member 93.

[0154] Based on the above structure, the housing 90 may include a support housing 92, or the support housing 92 may be omitted from the housing 90. In the embodiment where the housing 90 includes the support housing 92, the support housing 92 is rotatably connected to the structural member 93. Among them, the data acquisition device may further include a Hall magnet sensor.

The first magnetic body is connected to the support housing 92, and the second magnetic body is connected to the structural member 93. When the support housing 92 is closed relative to the structural member 93, the main board of the electronic device 1 controls the driving motor to move, so that the heat dissipation housing 91 is closed relative to the structural member 93. When the support housing 92 is opened relative to the structural member 93, the main board of the electronic device 1 controls the driving motor to move, so that the heat dissipation housing 91 is opened relative to the structural member 93.

[0155] The lifting mechanism 10 including the driving member 191 and the pushing block 192 described above is referred to as the first lifting mechanism 10a. A second lifting mechanism 10b may also be included between the support housing 92 and the structural member 93. Among them, the first lifting mechanism 10a and the second lifting mechanism 10b may be two independent structures. The first lifting mechanism 10a may be installed between the support housing 92 and the structural member 93, and the second lifting mechanism 10b may be installed between the heat dissipation housing 91 and the structural member 93.

[0156] Figure 26 It is a structural diagram of a second lifting mechanism in a closed state provided by an embodiment of the present application; Figure 27 It is a structural diagram of a second lifting mechanism in an open state provided by an embodiment of the present application; Figure 28 It is an exploded view of the structure of a second lifting mechanism provided by an embodiment of the present application. As Figure 26 、 Figure 27 and Figure 28 shown, the second lifting mechanism 10b may include a base 100, a flipping bracket 200, a transition slider 500, a first shaft core 410, and a bushing 700. Among them, the structures of the flipping bracket 200, the transition slider 500, the first shaft core 410, and the bushing 700 may be as described in the above embodiments, and will not be elaborated here. Correspondingly, the base 100 may also only include the mating chute 180, the first arc chute 110, and the third arc slider 120 in the above embodiments. The specific structure of the base 100 will not be elaborated here.

[0157] Combined with Figure 5 and Figure 6 , when the second lifting mechanism 10b is in the closed state, in the lifting direction Z, the distance between the first free end 200b of the flipping bracket 200 and the second surface N2 is the first distance D1. When the lifting mechanism 10 is in the open state, in the lifting direction Z, the distance between the first free end 200b of the flipping bracket 200 and the second surface N2 is the third distance D3, and the third distance D3 is greater than the first distance D1.

[0158] When the second lifting mechanism 10b is in the closed state, the flipping bracket 200 drives the support housing 92 to close relative to the second structural member 93. This is beneficial to saving the occupied space of the electronic device 1 when the electronic device 1 is in the closed state. When the second lifting mechanism 10b is in the open state, the flipping bracket 200 drives the support housing 92 to open relative to the structural member 93, which is beneficial to the support housing 92 to support the electronic device 1.

Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
