Lifting mechanism, housing and electronic device

Abstract

The embodiments of the present application relate to a lifting mechanism, a housing and an electronic device, which are used for solving the problem of relatively large thicknesses of electronic devices. The lifting mechanism comprises a base, a turn-over support, a lifting support and a linkage assembly. The turn-over support is rotatably connected to the base; the lifting support is movably connected to the base; the linkage assembly is connected to the turn-over support and the lifting support. In a closed state, the distance between a first free end of the turn-over support and a second surface is small, the distance between a second free end of the lifting support and the second surface is small, and the lifting support drives a heat dissipation housing to be closed with respect to a structural part, thus helping to reduce the thickness of an electronic device. In an open state, the distance between the first free end of the turn-over support and the second surface is large, and the distance between the second free end of the lifting support and the second surface is large, thus aiding in heat dissipation. In the process of the lifting mechanism switching from the closed state to the open state, by means of the linkage assembly, the turn-over support drives the lifting support to move in a lifting direction.

Lifting mechanism, housing and electronics

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 28, 2023, with application number 202311870430.4 and application name “Lifting mechanism, housing and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of electronic equipment, and in particular to a lifting mechanism, a housing, and an electronic device. Background Art

[0003] As tablet computer power consumption increases and performance improves, heat dissipation requirements are also becoming increasingly stringent. The inability to dissipate heat generated by high power consumption has become a bottleneck restricting tablet computer performance, making heat dissipation a key performance indicator for tablet computers. In related art, heat dissipation holes are typically provided on the tablet computer casing. However, these tablet computers are relatively thick, hindering the realization of a lightweight and thin device.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a lifting mechanism, a housing, and an electronic device, which are used to improve the problem of large thickness of electronic devices in related technologies.

[0006] To achieve the above objectives, the present invention provides the following solutions:

[0007] On the one hand, an embodiment of the present application provides a lifting mechanism, including a base, a flip bracket, a lifting bracket, and a linkage assembly. The base includes a first surface and a second surface relative to each other, and the direction from the second surface to the first surface is the lifting direction; the flip bracket includes a first connecting end and a first free end, and the first connecting end is rotatably connected to the base; the lifting bracket includes a second connecting end and a second free end, and the second connecting end is movably connected to the base; the linkage assembly connects the flip 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 flip bracket can be connected to the supporting shell of the electronic structure, and the second free end of the lifting bracket can be connected to the heat dissipation shell of the electronic structure. Through the above arrangement, when the flip bracket rotates relative to the base, the flip bracket can drive the supporting shell to rotate relative to the structural member; when the lifting bracket moves relative to the base, the lifting bracket can drive the heat dissipation shell to move relative to the structural member.

[0008] When the lifting mechanism is in a closed state, the distance between the first free end of the flip bracket and the second surface in the lifting direction 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 an open state, the distance between the first free end of the flip bracket and the second surface in the lifting direction is a third distance, and the distance between the second free end of the lifting bracket and the second surface is a fourth distance, wherein the third distance is greater than the first distance, and the fourth distance is greater than the second distance. During the transition of the lifting mechanism from a closed state to an open state, the flip bracket rotates in the lifting direction, and the flip bracket drives the lifting bracket in the lifting direction via the linkage assembly.

[0009] In summary, when the lifting mechanism is in a closed state, in the lifting direction, the distance between the first free end of the flip 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 flip bracket drives the support shell to close relative to the structural member, and the lifting bracket drives the heat dissipation shell to close relative to the structural member. This is beneficial for saving the space occupied by the electronic device when the electronic device is in a closed state, and is beneficial for reducing the thickness of the electronic device. When the lifting mechanism is in an open state, in the lifting direction, the distance between the first free end of the flip 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 flip bracket drives the support shell to open relative to the structural member, and the lifting bracket drives the heat dissipation shell to open relative to the structural member. This is beneficial for the support shell to support the electronic device, and at the same time, increases the airflow between the heat dissipation shell and the structural member, which is beneficial for improving the heat dissipation efficiency of the electronic device.

[0010] In some implementations, the rotation axis of the flip bracket relative to the base is a first axis, the lifting bracket is rotationally connected to the base, and the rotation axis of the lifting bracket relative to the base is a second axis, and the second axis is parallel to the first axis. Through the above arrangement, one end of the lifting bracket is rotationally connected to the base, and the other end of the lifting bracket can be connected to the heat dissipation housing. The other end of the lifting bracket moves relative to the base under the drive of 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, because 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 helps to improve the structural compactness of the lifting mechanism.

[0011] In some implementations, the base has a first curved slot, and the first connecting end of the flip bracket has a first curved slider, which is slidably connected to the first curved slot. With this arrangement, the base and the flip bracket can be rotatably connected together via a virtual axis rotational connection. When the first curved slider of the flip bracket slides within the first curved slot, the flip bracket rotates relative to the base.

[0012] In some implementations, the lifting bracket includes a lifting chute, and in a direction close to the second axis, the lifting chute has an inclined groove section that is inclined in a direction close to the second surface. The first end of the linkage assembly is fixedly connected to the flip bracket, and the second end of the linkage assembly is slidably connected to the lifting chute. 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. The above arrangement can achieve linkage between the flip bracket and the lifting bracket. When the electronic device is in the open state, the flip 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.

[0013] 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 flip 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 is rotationally 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 rotationally connected to the second end of the first connecting rod, the second end of the second connecting rod is located on a 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 slot. In summary, when the flip bracket rotates in a direction away from the base toward the support base, the flip bracket also drives the first shaft core to move in the first direction, the first shaft core drives the first connecting rod to move in the first direction, and the first connecting rod also rotates relative to the first shaft core. The first connecting rod drives the second connecting rod to move in the first direction, so that the second connecting rod slides relative to the lifting slot of the lifting bracket, and the lifting bracket rotates in a direction away from the base due to the drive of the second connecting rod.

[0014] In some implementations, the base further includes a guide groove extending parallel to the first direction. The linkage assembly further includes a second shaft core slidably connected to the guide groove, the axial direction of the second shaft core being parallel to the first axis. The second end of the first connecting rod is sleeved on and rotationally connected to the second shaft core, and the first end of the second connecting rod is sleeved on and rotationally connected to the second shaft core. This arrangement further ensures that the second connecting rod moves along the first direction when the flip bracket rotates relative to the base.

[0015] In some implementations, the base has a sliding hole extending along the first direction, the sliding hole being located on a side of the guide groove away from the first arcuate groove. The second connecting rod is slidably connected to the sliding hole, and the second end of the second connecting rod is located on a side of the sliding hole away from the lifting groove. With this arrangement, the second connecting rod can be slidably connected relative to the base along the first direction.

[0016] In some implementations, the lifting mechanism further includes an elastic member, wherein a first end of the elastic member is connected to the base, and a second end of the elastic member is connected to the lifting bracket. When the lifting mechanism is in a closed state, the elastic member is in a first state. When the lifting mechanism is in an open state, the elastic member is in a 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, and the elastic restoring force of the elastic member acts on the lifting mechanism, so that the lifting bracket is pressed relative to the base in a direction close to or away from the second surface, which is beneficial to reduce the fitting clearance between the lifting bracket and other structural members, and avoid shaking when the lifting mechanism moves.

[0017] In some implementations, the elastic member includes a first plate portion, a bent plate portion, and a second plate portion, the first plate portion and the second plate portion are both parallel to the second surface, the first plate portion is connected to the base, 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 the bent plate portion is bent in a direction closer to or away from the second surface. When the lifting mechanism is in a closed state, the first plate portion and the second plate portion have a first spacing in the lifting direction. When the lifting mechanism is in an open state, the first plate portion and the second plate portion have a second spacing in the lifting direction, and the second spacing is greater than the first spacing. Through the above arrangement, when the lifting mechanism is in a closed state, the first plate portion can be coplanar with the second plate portion, and the first spacing is zero in the lifting direction. When the lifting mechanism is in the open state, the second plate portion is away from the second surface relative to the first plate portion. In the lifting direction, the second spacing is greater than the first spacing. The elastic restoring force of the bent plate portion acts on the lifting mechanism, so that the lifting bracket is pressed relative to the base, which is beneficial to reducing the fitting clearance between the lifting bracket and other structural parts, and avoiding shaking when the lifting mechanism moves.

[0018] In some implementations, the lifting chute further comprises a first smooth chute segment and a second smooth chute segment, the inclined chute segment communicating between the first and second smooth chute segments, and the first smooth chute segment being spaced apart from the second axis relative to the second smooth chute segment. When the lifting mechanism is in a closed state, the second end of the linkage assembly is located within the first smooth chute segment, which extends in a first direction. With this arrangement, when the flip bracket is in a closed state relative to the base, since the first smooth chute segment extends in the first direction, the second end of the linkage assembly is located within the first smooth chute segment, thereby causing the lifting bracket to also be in a closed state relative to the base. When the lifting mechanism is in an open state, the second end of the linkage assembly is located within the inclined chute segment and the second smooth chute segment, which extend in the first direction. During the transition of the lifting mechanism from the closed state to the open state, the second end of the linkage assembly slides from the first smooth chute segment, via the inclined chute segment, to the second smooth chute segment. With this arrangement, when the flip bracket rotates relative to the base, the second end of the linkage assembly slides within the inclined chute segment, thereby driving the lifting bracket to rotate relative to the base, thereby causing the lifting bracket to also be in an open state relative to the base. When the flip bracket rotates to a certain angle relative to the base, the second end of the linkage assembly slides from the inclined groove section to the second smooth groove section. Since at this time, the second smooth groove section extends along the first direction, when the flip bracket continues to rotate relative to the base, the angle of rotation of the lifting bracket relative to the base remains unchanged, and the open state of the lifting bracket relative to the base does not change.

[0019] In some implementations, the lifting mechanism further comprises a sleeve, wherein a first end of the sleeve is sleeved on the first shaft core and rotatably connected to the first shaft core, the first end of the sleeve having an interference fit with the first shaft core, and a second end of the sleeve being slidably connected to the base in a direction perpendicular to the first axis. Through this arrangement, the interference fit between the first end of the sleeve and the first shaft core can provide torque, allowing the flip bracket to maintain a desired opening and closing angle when rotating relative to the base, and allowing the support housing to stably support the electronic device, preventing the electronic device from tipping over.

[0020] In some implementations, the lifting mechanism further comprises a transition slider, wherein the first end of the transition slider is rotationally connected to the base, and the second end of the transition slider is rotationally connected to the flip bracket. The rotation axis between the transition slider and the base is the first axis, and the rotation axis between the transition slider and the lifting bracket is the first axis. A support area is formed between the flip bracket and the base. Within the support area, and in a direction perpendicular to the first axis, the flip bracket shields the transition slider. Here, "support area" can be understood as a fan-shaped area sandwiched between the flip bracket and the base, and the support area is exposed to the user's field of view. Here, "shielding" can be understood as, within the support area, from a perspective perpendicular to the first axis, the flip bracket covers the transition slider so that the transition slider is not exposed to the user's field of view. Through the above arrangement, since the flip bracket covers the transition slider, the user is prevented from observing the phenomenon of asynchronous rotation angles of the transition sliders in multiple lifting mechanisms, thereby helping to improve the aesthetics of the lifting mechanism.

[0021] In some implementations, the flip bracket further comprises a second curved chute, the second curved chute being adjacent to the first curved slider, and the second end of the transition slider comprising a second curved slider being slidably connected to the second curved chute. Through the above arrangement, the flip bracket and the transition slider can be rotatably connected together via a rotational connection about a virtual axis. The base further comprises a third curved slider, the third curved slider being adjacent to the first curved chute, the first end of the transition slider comprising a third curved chute and a fourth curved slider being adjacent to the fourth curved slider, the third curved slider being slidably connected to the third curved chute, the fourth curved slider and the first curved slider being co-located within the first curved chute, and the fourth curved slider being slidably connected to the first curved chute. Through the above arrangement, the base and the transition slider can be rotatably connected together via a rotational connection about a virtual axis. In a direction parallel to the first axis, the first end of the transition slider is flush with the first curved slider, or the first curved slider extends beyond the first end of the transition slider. With the above arrangement, within the support area, at a viewing angle perpendicular to the first axis, the flip bracket covers the transition slider, so that the transition slider is not exposed to the user's field of view.

[0022] In some implementations, the second curved groove includes a first curved surface and a second curved surface disposed opposite each other, the first curved surface being spaced away from the first axis relative to the second curved surface, the first curved surface being adjacent to the first curved slider, and a portion of the first curved surface being recessed away from the first axis to form a curved mating groove. The transition slider includes a curved guide rail disposed circumferentially along the transition slider, the curved guide rail being slidably connected to the curved mating groove. This arrangement prevents the transition slider from deflecting due to lateral forces when the flip bracket rotates relative to the transition slider, thereby improving the rotational reliability between the flip bracket and the transition slider.

[0023] 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. The above arrangement is conducive to improving the structural compactness of the lifting mechanism.

[0024] In some implementations, the second axis is located between the first free end and the second free end. With this 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, thereby preventing interference between the support housing and the heat dissipation housing during transition of the electronic device from a closed state to an open state.

[0025] On the other hand, a shell is provided, comprising a lifting mechanism, a structural member, a supporting shell and a heat dissipation shell as in any of the above embodiments, wherein the supporting shell and the heat dissipation shell are located on the same side of the structural member, the supporting shell is rotatably connected to the structural member, the flip bracket of the lifting mechanism is located between the structural member and the supporting shell, the heat dissipation shell is rotatably connected to the structural member, the lifting bracket of the lifting mechanism is located between the structural member and the heat dissipation shell, the base is connected to the structural member, the flip bracket is connected to the supporting shell, and the lifting bracket is connected to the heat dissipation shell.

[0026] When the lifting mechanism is in the closed state, the supporting housing is closed relative to the structural member by the lifting mechanism, and the heat dissipation housing is closed relative to the structural member by the lifting mechanism. When the lifting mechanism is in the open state, the supporting housing is opened relative to the structural member by the lifting mechanism, and the supporting housing is used to support the structural member, while the heat dissipation housing is opened relative to the structural member by the lifting mechanism. The heat dissipation housing has heat dissipation holes that communicate with the external environment. The housing provided in the embodiments of the present application includes the lifting mechanism as described above, and thus has all the advantages described above, which will not be repeated here.

[0027] In some implementations, the heat dissipation housing includes a cover plate and a side plate, the side plate is arranged around the edge of the cover plate, and the side plate is located on the side of the cover plate facing the structural member, and the side plate has a heat dissipation hole running through it. When the lifting mechanism is in a closed state, the heat dissipation hole is located within the orthographic projection of the structural member on the side plate. Through the above arrangement, the structural member shields the heat dissipation hole on the side plate, which is beneficial to reducing the thickness of the electronic device when the electronic device does not need to dissipate heat. When the lifting mechanism is in an open state, at least part of the heat dissipation hole is located outside the orthographic projection of the structural member on the side plate. Through the above arrangement, the heat dissipation hole on the side plate is exposed, which is beneficial to improving the heat dissipation efficiency of the electronic device when the electronic device needs to dissipate heat.

[0028] In another aspect, an electronic device is provided, comprising a housing as described in any of the above embodiments, and a display module, wherein the display module is connected to a structural member of the housing and is located on a side of the structural member away from the supporting housing and the heat dissipation housing. The electronic device provided in the embodiments of the present application includes the above-described housing and thus has all the aforementioned beneficial effects, which will not be further elaborated here.

[0029] In another aspect, a housing is provided, comprising a lifting mechanism, a structural member, and a heat dissipation housing. 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 push block, wherein the driving member is connected to the structural member, and the push block is connected to the driving member. The push block has a first inclined surface, and the heat dissipation housing has a second inclined surface on a side facing the structural member that mates with the first inclined surface. When the lifting mechanism transitions between a closed state and an open state, the driving member drives the push block to move in a direction parallel to the structural member.

[0030] With the above arrangement, when the push block moves in a direction parallel to the structural member, the first inclined surface moves in a direction parallel to the structure, causing the second inclined surface to slide relative to the first inclined surface, thereby opening the heat dissipation housing relative to the structural member, increasing the airflow between the heat dissipation housing and the structural member, and facilitating improved heat dissipation efficiency of the electronic device. When the push block moves in a direction parallel to the structural member and in the opposite direction, the heat dissipation housing closes relative to the structural member.

[0031] In some implementations, the drive member includes a drive motor and a screw, wherein a drive shaft of the drive motor is connected to the screw, which is in turn threadedly connected to a push block. With this arrangement, the drive shaft of the drive motor drives the screw to rotate, causing the push block, which is threadedly connected to the screw, to move along the extension direction of the screw. The first inclined surface moves in a direction parallel to the structure, causing the second inclined surface to slide relative to the first inclined surface, thereby causing the heat dissipation housing to rotate relative to the structural member, thereby increasing the airflow between the heat dissipation housing and the structural member and facilitating improved heat dissipation efficiency of the electronic device.

[0060] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0061] In the following, the terms "first," "second," etc., are used for descriptive convenience only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0062] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0063] In the embodiments of the present application, directional indications such as up, down, left, right, front, and back, used to explain the structure and movement of various components of the present application are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0064] The present application provides an electronic device, which may be a mobile phone, a tablet computer (pad), a television, a smart wearable product (e.g., a smart watch, a smart bracelet), a virtual reality (VR) device, an augmented reality (AR) device, or other terminal products.

[0065] Figure 1 is a structural diagram of an electronic device in a closed state according to an embodiment of the present application; Figure 2 is a structural diagram of an electronic device in an open state according to an embodiment of the present application; and Figure 3 is an exploded view of the structure of an electronic device according to an embodiment of the present application. The electronic device according to the embodiment of the present application will be described below with reference to Figures 1, 2, and 3.

[0066] 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. The display module 80 may include a display panel, and the display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-oLed, a quantum dot light-emitting diode (QLED), etc.

[0067] The housing 90 may include a structural member 93, which 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.

[0068] In some embodiments, the electronic device 1 includes multiple functional components (not shown in the figure), and the multiple functional components can be installed on the structural member 93. The multiple 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 jack, a sensor module, a button, a motor, an indicator, and a subscriber identification module (SIM) card interface. Among them, the electronic device 1 may have more or fewer components than 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.

[0069] Continuing with Figure 3 , the housing 90 may further include a support shell 92 and a lifting mechanism 10. The support shell 92 may be rotatably connected to the structural member 93 and may be located on a 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 may also be connected to the support shell 92 to drive the support shell 92 to rotate relative to the structural member 93.

[0070] As shown in Figure 1 , when the lifting mechanism 10 is in the closed state, the support housing 92 is closed relative to the structural member 93 via 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 components within the midframe structure and also serves to partially present the appearance of the foldable electronic device 1.

[0071] As shown in FIG2 , when the lifting mechanism 10 is in the open state, the support housing 92 is opened relative to the structural member 93 by the lifting mechanism 10, and the support housing 92 is used to support the structural member 93. For example, the 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 to allow the user to apply force and to support the structural member 93. The lifting mechanism 10 is used to achieve the rotation of the support housing 92 and provide torque to maintain the support housing 92 at a certain opening and closing angle.

[0072] 1 and 3 , the housing 90 may further include an inner housing 94, which is positioned between the outer support housing 92 and the structural member 93, and the lifting mechanism 10 is positioned between the inner housing 94 and the structural member 93. When the outer 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, thereby improving the aesthetics.

[0073] In one embodiment, electronic device 1 includes, but is not limited to, a two-in-one product, an all-in-one computer, and a mobile phone. A two-in-one product typically includes a main unit and a keyboard assembly. The main unit and keyboard assembly are detachably connected. After being separated from the keyboard assembly, the main unit can still function as an independent electronic device 1. For example, the main unit may be a tablet computer. The main unit may include a structural member 93 of the electronic device 1, a display module 80 and functional components fixed to the structural member 93, a support housing 92 may be located on the back of the main unit to support the main unit, and a hinge device may be located between the main unit and the support member.

[0074] Based on the above structure, in some embodiments, the structural member 93 may further be provided with heat dissipation holes. For example, the heat dissipation holes may be located on the side of the structural member 93 or at the top of the structural member 93. However, providing multiple heat dissipation holes on the structural member 93 may easily increase the thickness of the structural member 93, thereby increasing the thickness of the electronic device 1. Furthermore, providing multiple heat dissipation holes on the structural member 93 may affect the aesthetics of the electronic device 1.

[0075] Figure 4 is a structural diagram of a heat dissipation housing provided in an embodiment of the present application. In conjunction with Figure 4, in view of this, the housing 90 may further include a heat dissipation housing 91, which may be rotatably connected to a structural member 93. The heat dissipation housing 91 and the support housing 92 are located on the same side of the structural member 93, and the display module 80 is located on a side of the structural member 93 away from the support housing 92 and the heat dissipation housing 91. Accordingly, at least a portion of the lifting mechanism 10 provided in this 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 is used to drive the heat dissipation housing 91 to rotate relative to the structural member 93.

[0076] As shown in Figure 1 , when the lifting mechanism 10 is in the closed state, the support housing 92 is closed relative to the structural member 93 by the lifting mechanism 10, and the heat dissipation housing 91 is also closed relative to the structural member 93 by the lifting mechanism 10. For example, the heat dissipation housing 91 and the structural member 93 are parallel to each other. With this arrangement, 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 helps save space.

[0077] As shown in Figure 2, when the lifting mechanism 10 is in the open position, the support housing 92 is opened relative to the structural member 93 by 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 by the lifting mechanism 10, and the heat dissipation housing 91 exposes heat dissipation holes 915 that communicate with the external environment. For example, the angle between the heat dissipation housing 91 and the structural member 93 is a2 (a2 can be, for example, 5°, 8°, or 10°). With this arrangement, when a user uses the electronic device 1, the lifting mechanism 10 is in the open position, and the support housing 92 is opened relative to the structural member 93, which facilitates supporting the electronic device 1 and meets the user's usage needs in different scenarios. At the same time, the heat dissipation housing 91 is opened relative to the structural member 93, and the heat dissipation holes 915 that communicate with the external environment are exposed, which facilitates heat dissipation of the electronic device 1. Compared to directly providing the heat dissipation holes 915 on the structural member 93, this helps reduce the thickness of the electronic device 1.

[0078] In some embodiments, with continued reference to FIG4 , 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 is located on the side of the cover plate 911 facing the structural member 93. The side plate 913 has a through-hole 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 FIG3 , 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.

[0079] 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 panel 913. For example, when the lifting mechanism 10 is in the closed state, the cover 911 of the heat dissipation housing 91 can be parallel to the bottom of the accommodating groove 931, and the side panel 913 of the heat dissipation housing 91 can be located within the accommodating groove 931, so that the heat dissipation holes 915 can be located within the orthographic projection of the groove wall of the accommodating groove 931 on the side panel 913. Through this arrangement, the structural member 93 shields the heat dissipation holes 915 on the side panel 913, which helps reduce the thickness of the electronic device 1 when heat dissipation is not required.

[0080] When the lifting mechanism 10 is in the open state, at least some of the heat dissipation holes 915 are located outside the orthographic projection of the structural member 93 on the side panel 913. For example, when the lifting mechanism 10 is in the open state, the plane on which the cover plate 911 lies can be at an angle to the plane on which the bottom of the accommodating groove 931 lies, and at least some of the heat dissipation holes 915 can be located outside the accommodating groove 931, so that at least some of the heat dissipation holes 915 can be located outside the orthographic projection of the groove wall of the accommodating groove 931 on the side panel 913. Through this arrangement, the heat dissipation holes 915 on the side panel 913 are exposed, which helps improve the heat dissipation efficiency of the electronic device 1 when heat dissipation is required.

[0081] FIG5 is a structural diagram of a lifting mechanism provided in an embodiment of the present application in a closed state; FIG6 is a structural diagram of a lifting mechanism provided in an embodiment of the present application in an open state; FIG7 is a structural diagram of another lifting mechanism provided in an embodiment of the present application in an open state;

[0082] Figure 8 is an exploded view of the structure of a lifting mechanism provided in an embodiment of the present application. The lifting mechanism provided in an embodiment of the present application will be described below in conjunction with Figures 5, 6, 7 and 8.

[0083] In some embodiments, the lifting mechanism 10 may include a base 100, a flip bracket 200, a lifting bracket 300, and a linkage assembly 400. The base 100 may include a first surface N1 and a second surface N2 relative to each other, and the direction from the second surface N2 to the first surface N1 is a lifting direction Z. Exemplarily, the base 100 may include a bottom surface and a top surface relative to each other, the top surface may be the first surface N1, and the bottom surface may be the second surface N2. The bottom surface may contact the structural member 93. For example, the bottom surface may contact the bottom of the accommodating groove 931 and be parallel to the bottom of the accommodating groove 931. The top surface may be a surface away from the structural member 93.

[0084] In some embodiments, the flip bracket 200 can be rotatably connected to the base 100. The flip bracket 200 can include a first connection end 200a and a first free end 200b, with the first connection end 200a being rotatably connected to the base 100. The lifting bracket 300 can be movably connected to the base 100. The lifting bracket 300 can include a second connection end 300a and a second free end 300b, with the second connection end 300a being movably connected to the base 100. The linkage assembly 400 can connect the flip bracket 200 and the lifting bracket 300.

[0085] The second surface N2 of the base 100 can be connected to the structural member 93, the first free end 200b of the flip 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. With this arrangement, when the flip bracket 200 rotates relative to the base 100, the flip bracket 200 can drive the support housing 92 to rotate relative to the structural member 93; and 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.

[0086] 8 , the base 100 may include a first support member 100a and a second support member 100b, which may be enclosed by a frame. The base 100 may be connected to the structural member 93 by threaded fasteners such as bolts.

[0087] The rotation axis of the flip bracket 200 relative to the base 100 can be the first axis L1. For the convenience of explanation 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.

[0088] 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 flip bracket 200 and the second surface N2 is a first distance D1, and the distance between the second free end 300b of the lifting bracket 300 and the second surface N2 is a 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 flip bracket 200 and the second surface N2 is a third distance D3, and the distance between the second free end 300b of the lifting bracket 300 and the second surface N2 is a 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.

[0089] With the above arrangement, when the lifting mechanism 10 is in the closed state, the flip 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, thereby placing the electronic device 1 in the closed state. When the lifting mechanism 10 is in the open state, the flip 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, thereby placing the electronic device 1 in the open state.

[0090] During the transition of the lifting mechanism 10 from the closed state to the open state, the flip bracket 200 rotates toward the lifting direction Z, and the flip bracket 200 drives the lifting bracket 300 to move in the lifting direction Z through the linkage assembly 400. For example, during the transition of the lifting mechanism 10 from the closed state to the open state, the first free end 200b of the flip bracket 200 can rotate toward the lifting direction Z. The lifting bracket 300 can be connected to the flip bracket 200 through the linkage assembly 400, and when the flip bracket 200 moves, the linkage assembly 400 drives the lifting bracket 300 to move. For example, during the transition of the lifting mechanism 10 from the closed state to the open state, the flip 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.

[0091] In summary, when the lifting mechanism 10 is in the closed state, the flip bracket 200 drives the support shell 92 to close relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation shell 91 to close relative to the structural member 93. This is beneficial for saving the space occupied by the electronic device 1 when the electronic device 1 is in the closed state, and is beneficial for reducing the thickness of the electronic device 1. When the lifting mechanism 10 is in the open state, the flip bracket 200 drives the support shell 92 to open relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation shell 91 to open relative to the structural member 93. This is beneficial for the support shell 92 to support the electronic device 1, and at the same time, increases the airflow between the heat dissipation shell 91 and the structural member 93, which is beneficial for improving the heat dissipation efficiency of the electronic device 1.

[0092] In some embodiments, the lifting mechanism 10 may be rotatably connected to the base 100. For example, the second connection end 300a of the lifting mechanism 10 may be rotatably connected to the base 100, and the second free end 300b of the lifting mechanism 10 may 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 along the lifting direction Z. Alternatively, in some other embodiments, the lifting mechanism 10 may be transmission-connected to the base 100. For example, the base 100 may 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 along the lifting direction Z.

[0093] FIG9 is an assembly structure diagram of a flip bracket and a transition slider provided in an embodiment of the present application, wherein FIG9 (a) is a structural diagram of the flip bracket and the transition slider in one relative rotation state, and FIG9 (b) is a structural diagram of the flip bracket and the transition slider in another relative rotation state; FIG10 is an exploded structural diagram of a flip bracket and a transition slider provided in an embodiment of the present application. Referring to FIG8, FIG9 and FIG10, the base 100 may have a first arcuate chute 110, and the first connecting end 200a of the flip bracket 200 may have a first arcuate slider 220, and the first arcuate slider 220 may be slidably connected to the first arcuate chute 110. Exemplarily, the base 100 may include two first arcuate chute 110, and the two first arcuate chute 110 are respectively recorded as a first sub-chute 110a and a second sub-chute 110b.

[0094] Figure 11 is a structural diagram of a base provided in an embodiment of the present application. Referring to Figure 11 , a first support member 100a and a second support member 100b may be arranged along a second direction X. The first support member 100a may include a first extension portion 101a extending along a first direction Y, and the second support member 100b may include a second extension portion 101b extending along the first direction Y. The first extension portion 101a may have a first sub-slot 110a on the side facing the second extension portion 101b, and the second extension portion 101b may have a second sub-slot 110b on the side facing the first extension portion 101a.

[0095] Accordingly, referring to FIG10 , the flip bracket 200 may include a first body 210 and two first curved sliders 220 . The first body 210 is configured to connect to the support housing 92 . The two first curved sliders 220 are referred to as a first sub-slider 220 a and a second sub-slider 220 b . For example, the first sub-slider 220 a and the second sub-slider 220 b are each connected to the first body 210 and arranged along the second direction X. The first sub-slider 220 a is slidably connected to the first sub-slider groove 110 a, and the second sub-slider 220 b is slidably connected to the first sub-slider groove 110 a.

[0096] Through the above arrangement, the base 100 and the flip bracket 200 can be rotatably connected together via a virtual axis rotational connection. When the first curved slider 220 of the flip bracket 200 slides within the first curved slot 110, the flip bracket 200 rotates relative to the base 100. The centerline of the first curved slider 220 coincides with the centerline of the first curved slot 110. Furthermore, the centerline of the first curved slider 220 is also the first axis L1, and the centerline of the first curved slot 110 is also the first axis L1. The first axis L1 can be a virtual axis and can be located on the side of the base 100 closer to the first surface N1.

[0097] Of course, in some other embodiments, the base 100 may have a first arc-shaped slider 220, the first connecting end 200a of the flip bracket 200 may have a first arc-shaped groove 110, and the first arc-shaped slider 220 may be slidably connected to the first arc-shaped groove 110, so that the base 100 and the flip bracket 200 can be rotatably connected together through a rotational connection of a virtual axis.

[0098] Continuing to refer to Figures 8, 9 and 10, the lifting mechanism 10 can also include a transition slider 500, the first end of the transition slider 500 is rotatably connected to the base 100, the second end of the transition slider 500 is rotatably connected to the flip bracket 200, the rotation axis between the transition slider 500 and the base 100 is the first axis L1, and the rotation axis between the transition slider 500 and the lifting bracket 300 is the first axis L1.

[0099] For example, the lifting mechanism 10 may include two transition sliders 500, which are referred to as a first transition slider 500a and a second transition slider 500b, respectively. The first transition slider 500a may be connected between the base 100 and the flip bracket 200, and the second transition slider 500b may be connected between the base 100 and the flip bracket 200. With this arrangement, the first curved slider 220 of the flip bracket 200 rotates relative to the transition slider 500, and the transition slider 500 rotates relative to the first curved slot 110 of the base 100, thereby increasing the rotation angle of the flip bracket 200 relative to the base 100 and meeting user needs in different scenarios.

[0100] In some embodiments, as shown in Figures 6 and 7 , a support area S can be formed between the flip bracket 200 and the base 100. Within the support area S, and along a direction perpendicular to the first axis L1, the flip bracket 200 shields the transition slider 500. Here, "support area S" can be understood as the fan-shaped area sandwiched between the flip bracket 200 and the base 100, and the support area S is exposed to the user's field of view. Here, "shielding" can be understood as meaning that within the support area S, from a perspective perpendicular to the first axis L1, the flip bracket 200 covers the transition slider 500, preventing the transition slider 500 from being exposed to the user's field of view.

[0101] It will be appreciated that during the rotation of the flip bracket 200 relative to the base 100, the rotational position of the transition slider 500 relative to the base 100 is not fixed; that is, the rotational angle of the transition slider 500 relative to the base 100 is not fixed. To achieve a good support effect for the supporting housing 92, the electronic device 1 typically includes multiple lifting mechanisms 10. With this arrangement, since the flip bracket 200 covers the transition slider 500, the user is prevented from observing the asynchronous rotation angles of the transition sliders 500 in the multiple lifting mechanisms 10, thereby improving the aesthetics of the lifting mechanisms 10.

[0102] Continuing to refer to Figures 9 and 10, the flip bracket 200 can also have a second arc-shaped slide groove 230, which is adjacent to the first arc-shaped slider 220, and the second end of the transition slider 500 has a second arc-shaped slider 521, which is slidably connected to the second arc-shaped slide groove 230.

[0103] Exemplarily, the flip bracket 200 may further include two second arc-shaped slide grooves 230, which are referred to as a third sub-slide groove 230a and a fourth sub-slide groove 230b, wherein the third sub-slide groove 230a is adjacent to the first sub-slide block 220a, and the third sub-slide groove 230a is closer to the first axis L1 than the first sub-slide block 220a; the fourth sub-slide groove 230b is adjacent to the second sub-slide block 220b, and the fourth sub-slide groove 230b is closer to the first axis L1 than the second sub-slide block 220b.

[0104] Correspondingly, the two second arc-shaped sliders 521 are recorded 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 slidingly connected to the third sub-slider 230a; the second end of the second transition slider 500b can have a fourth sub-slider 521b, and the fourth sub-slider 521b is slidingly connected to the fourth sub-slider 230b.

[0105] Through the above arrangement, the flip bracket 200 and the transition slider 500 can be rotatably connected together via a virtual axis rotational connection. When the second end of the transition slider 500 slides within the second arcuate slot 230, the flip bracket 200 rotates relative to the transition slider 500. The centerline of the second arcuate slider 521 and the centerline of the second arcuate slot 230 coincide with each other. Furthermore, the centerline of the second arcuate slider 521 is also the first axis L1, and the centerline of the second arcuate slot 230 is also the first axis L1. Therefore, the rotation axis of the flip bracket 200 relative to the transition slider 500 is the first axis L1.

[0106] Alternatively, in some other embodiments, the flip bracket 200 may also have a second arc-shaped slider 521, the second end of the transition slider 500 has a second arc-shaped groove 230, and the second arc-shaped slider 521 is slidingly connected to the second arc-shaped groove 230, so that the flip bracket 200 and the transition slider 500 can be rotatably connected together through a rotational connection of a virtual axis.

[0107] Based on the above structure, referring again to Figure 10 , a portion of the wall of the second curved chute 230 protrudes to form the first stop block 250. Accordingly, the second curved slider 521 also has a second stop block 5213 that cooperates with the first stop block 250. When the flip bracket 200 rotates to a certain angle relative to the transition slider 500, the first stop block 250 and the second stop block 5213 abut against each other, stopping the flip bracket 200 from rotating relative to the transition slider 500. This helps prevent the flip bracket 200 from separating from the transition slider 500 during rotation, thereby improving the rotational reliability between the flip bracket 200 and the transition slider 500.

[0108] Continuing with reference to Figures 8 and 10, the base 100 also has a third curved slider 120, which is adjacent to the first curved slot 110. The first end of the transition slider 500 has a third curved slot 511 and a fourth curved slider 512, which are adjacent to the fourth curved slider 512. The third curved slider 120 is slidingly connected to the third curved slot 511, and the fourth curved slider 512 and the first curved slider 220 are slidingly connected to the first curved slot 110.

[0109] Exemplarily, the base 100 may further include two third curved sliders 120, which are referred to as the fifth sub-slider 120a and the sixth sub-slider 120b, wherein the fifth sub-slider 120a is adjacent to the first sub-slider 110a, and the fifth sub-slider 120a is closer to the first axis L1 than the first sub-slider 110a; the sixth sub-slider 120b is adjacent to the second sub-slider 110b, and the sixth sub-slider 511b is closer to the first axis L1 than the second sub-slider 220b.

[0110] Correspondingly, the two third arc-shaped slots 511 are recorded as the fifth sub-slot 511a and the sixth sub-slot 511b, and the two fourth arc-shaped sliders 512 are recorded as the seventh sub-slot 512a and the eighth sub-slot 512b. The first end of the first transition slider 500a can have adjacent fifth sub-slot 511a and seventh sub-slot 512a, and the seventh sub-slot 512a is farther away from the first axis L1 than the fifth sub-slot 511a. The seventh sub-slot 512a is slidably connected to the first sub-slot 220a and the first sub-slot 110a, and the fifth sub-slot 120a is in the fifth sub-slot 511a. The first end of the second transition slider 500b can have an adjacent sixth sub-slide 511b and an eighth sub-slide 512b, and the eighth sub-slide 512b is farther away from the first axis L1 than the sixth sub-slide 511b. The eighth sub-slide 512b is slidingly connected to the second sub-slide 220b and the second sub-slide 110b, and the sixth sub-slide 120b is slidingly connected to the sixth sub-slide 511b.

[0111] With the above arrangement, the base 100 and the transition slider 500 can be rotatably connected together via a virtual axis rotational connection. When the third curved slider 120 slides within the first end of the transition slider 500, the transition slider 500 rotates relative to the base 100. The centerline of the third curved slider 120 coincides with the centerline of the third curved slot 511. Furthermore, the centerline of the third curved slider 120 is also the first axis L1, and the centerline of the third curved slot 511 is also the first axis L1. Therefore, the rotation axis of the transition slider 500 relative to the base 100 is the first axis L1.

[0112] Alternatively, in some other embodiments, the base 100 further has a third arc-shaped groove 511, the first end of the transition slider 500 has a third arc-shaped slider 120, and the third arc-shaped slider 120 is slidingly connected to the third arc-shaped groove 511, so that the base 100 and the transition slider 500 can be rotatably connected together through a rotational connection of a virtual axis.

[0113] Based on the above structure, the first end of the first transition slider 500a can protrude to form a third stop block 513. Accordingly, the third curved slider 120 also has a fourth stop block 130 that cooperates with the third stop block 513. When the transition slider 500 rotates to a certain angle relative to the base 100, the third stop block 513 and the fourth stop block 130 abut against each other, stopping the transition slider 500 from rotating relative to the base 100. This helps prevent the transition slider 500 from separating from the base 100 during rotation, thereby improving the rotational reliability between the transition slider 500 and the base 100.

[0114] In a direction parallel to the first axis L1 , the first end of the transition slider 500 is flush with the first curved slider 220 , or the first curved slider 220 exceeds the first end of the transition slider 500 .

[0115] For example, in a direction parallel to the first axis L1, the fourth curved slider 512 and the third stop block 513 of the transition slider 500 may both be flush with the first curved slider 220, or the first curved slider 220 may extend beyond the fourth curved slider 512 and the third stop block 513 of the transition slider 500. With the above arrangement, within the support area S, from a perspective perpendicular to the first axis L1 (e.g., perspective P in Figures 6 and 7 ), the flip bracket 200 covers the transition slider 500, preventing the transition slider 500 from being exposed to the user's field of view.

[0116] Based on the above structure, referring to FIG10 , the second curved groove 230 may include a first curved surface 231 and a second curved surface 232. The first curved surface 231 is spaced away from the first axis L1 relative to the second curved surface 232, and the first curved surface 231 is adjacent to the first curved slider 220. A portion of the first curved surface 231 is recessed away from the first axis L1 to form the curved mating groove 240. Accordingly, the transition slider 500 includes a curved guide rail 530 disposed along the circumference of the transition slider 500 and slidably connected to the curved mating groove 240.

[0117] For example, the centerline of the arcuate matching groove 240 can be the first axis L1, and the centerline of the arcuate slide rail 530 can also be the first axis L1. With this arrangement, when the flip bracket 200 rotates relative to the transition slider 500, the transition slider 500 is prevented from deflecting due to lateral forces, thereby improving the rotational reliability between the flip bracket 200 and the transition slider 500.

[0118] In some embodiments, the lifting bracket 300 may be rotatably connected to the base 100 , and 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 .

[0119] Continuing with reference to FIG8 , the lifting bracket 300 may include two lifting members arranged along the second direction X, which are denoted as a first lifting member 300c and a second lifting member 300d. The base 100 may further include two bosses 150 arranged opposite each other along the second direction X, one of the bosses 150 being located on a side of the first extension portion 101a of the first support member 100a away from the second support member 100b, and the other boss 150 being located on a 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 onto the boss 150 of the first support member 100a to enable the first lifting member 300c to be rotatably connected to the first support member 100a; one end of the second lifting member 300d may be sleeved onto the boss 150 of the second support member 100b to enable the second lifting member 300d to be rotatably connected to the second support member 100b.

[0120] Through 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. Driven by the linkage assembly 400, the other end of the lifting bracket 300 moves relative to the base 100, thereby causing the other end of the lifting bracket 300 to drive the heat dissipation housing 91 to open or close relative to the base 100. At the same time, because 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 helps to improve the structural compactness of the lifting mechanism 10.

[0121] In addition, the lifting mechanism 10 may further include two spring buckles 600, one spring buckle 600 being sleeved on a rotating shaft and located on a side of the lifting bracket 300 away from the base 100. Through the above arrangement, the lifting bracket 300 is prevented from being separated from the base 100 during rotation.

[0122] 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. The above arrangement is conducive to improving the structural compactness of the lifting mechanism 10. Furthermore, 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 flip bracket 200. The above arrangement allows the rotation direction of the support housing 92 relative to the base 100 to be opposite to the rotation direction of the heat dissipation housing 91 relative to the base 100, thereby preventing interference between the support housing 92 and the heat dissipation housing 91 during the transition of the electronic device 1 from a closed state to an open state.

[0123] FIG12 is an exploded view of the structure of another lifting mechanism provided in an embodiment of the present application. In combination with FIG8 and FIG12, in some embodiments, the lifting bracket 300 may include a lifting slot 310, and in the direction close to the second axis L2, the lifting slot 310 has an inclined slot section 311 inclined in the direction close to the second surface N2. Exemplarily, the inclined slot section 311 may be in the shape of a strip, and in the direction close to the second axis L2, the extension direction of the length of the inclined slot section 311 may be inclined in the direction close to the second surface N2. Among them, the first lifting member 300c may have a lifting slot 310 on the side facing the second lifting member 300d, and the second lifting member 300d may also have a lifting slot 310 on the side facing the first lifting member 300c.

[0124] Accordingly, the first end 400a of the linkage assembly can be fixedly connected to the flip bracket 200, and the second end 400b of the linkage assembly can be slidably connected to the lifting slot 310. The linkage assembly 400 is also slidably connected to the base 100 along a first direction Y. The first direction Y is parallel to the second surface N2 and perpendicular to the second axis L2. Because the flip bracket 200 and the base 100 are rotationally connected via a virtual axis, when the flip bracket 200 rotates relative to the base 100, the flip bracket 200 also moves relative to the base 100. Illustratively, when the flip bracket 200 rotates toward the lifting direction Z (the rotation direction may be the clockwise direction B1 shown in FIG12 ), the flip bracket 200 also drives the linkage assembly 400 to move (the movement direction may be the translation direction B2 shown in FIG12 ), so that the second end 400b of the linkage assembly slides relative to the lifting slot 310 of the lifting bracket 300, and the lifting bracket 300 rotates toward the lifting direction Z (the rotation direction may be the counterclockwise direction B3 shown in FIG12 ) driven by the linkage assembly 400.

[0125] To sum up, the above-mentioned setting can realize the linkage of the flip bracket 200 and the lifting bracket 300. When the electronic device 1 is in the open state, the flip bracket 200 drives the supporting shell 92 to open relative to the structural member 93, and the lifting bracket 300 drives the heat dissipation shell 91 to open relative to the structural member 93. While the supporting shell 92 can support the electronic device 1, the heat dissipation shell 91 can also improve the heat dissipation efficiency of the electronic device 1.

[0126] In some embodiments, the lifting bracket 300 may also include a first smooth groove section 313 and a second smooth groove section 312, the inclined groove section 311 is connected between the first smooth groove section 313 and the second smooth groove section 312, and the first smooth groove section 313 is away from the second axis L2 relative to the second smooth groove section 312.

[0127] When the lifting mechanism 10 is in the closed state, the second end 400 b 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. With the above arrangement, when the flip 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, the second end 400 b of the linkage assembly is located in the first smooth groove section 313 , thereby keeping the lifting bracket 300 in the closed state relative to the base 100 .

[0128] When the lifting mechanism 10 is in the open state, the second end 400b of the linkage assembly is located within 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 transition of the lifting mechanism 10 from the closed state to the open state, the second end 400b of the linkage assembly slides from the first smooth groove section 313, through the inclined groove section 311, to the second smooth groove section 312. With this arrangement, when the flip bracket 200 rotates relative to the base 100, the second end 400b of the linkage assembly slides within the inclined groove section 311, thereby driving the lifting bracket 300 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 flip bracket 200 rotates to a certain angle relative to the base 100, the second end 400b of the linkage assembly slides from the inclined groove section 311 to the second smooth groove section 312. Since at this time, the second smooth groove section 312 extends along the first direction Y, when the flip 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.

[0129] The lengths of the first smooth groove section 313 and the second smooth groove section 312 can be set according to actual needs, and the embodiment of the present application does not impose any special limitation on this.

[0130] Figure 13 is a diagram illustrating the assembly structure of a base, a flip bracket, and a linkage assembly according to an embodiment of the present application; Figure 14 is an exploded view of the assembly structure in Figure 13; and Figure 15 is an exploded view of the flip bracket and linkage assembly according to an embodiment of the present application. The linkage assembly according to an embodiment of the present application will be described below in conjunction with Figures 13, 14, and 15.

[0131] 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. 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 arrangement, the lifting bracket 300 can be connected to the flip bracket 200 via the linkage assembly 400.

[0132] 15 , the first shaft core 410 can be fixedly connected to the flip bracket 200, with the axial direction of the first shaft core 410 being parallel to the first axis L1. The first end 421 of the first connecting rod is sleeved on the first shaft core 410 and rotatably connected to the first shaft core 410, with the first end 421 of the first connecting rod having 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, with the first end 441 of the second connecting rod being rotatably connected to the second end 422 of the first connecting rod. The second end 442 of the second connecting rod is located on a 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.

[0133] For example, the flip bracket 200 may include two fixing holes 550 arranged along the second direction X. The fixing holes 550 are located on a side of the flip bracket 200 away from the first curved slider 220. The two 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, thereby fixedly connecting the first shaft core 410 to the flip bracket 200. The first end 421 of the first connecting rod may have a first connecting hole 4213 extending along the second direction X. The first connecting hole 4213 has a clearance fit with the first shaft core 410, thereby achieving a rotational connection between the first end 421 of the first connecting rod and the first shaft core 410.

[0134] 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 connecting rod is sleeved on the second shaft core 430 and is rotatably connected to the second shaft core 430, and the first end 441 of the second connecting rod is sleeved on the second shaft core 430 and is rotatably connected to the second shaft core 430. Exemplarily, the second end 422 of the first connecting rod may have a second connecting hole 4215 extending along the second direction X, and the second connecting hole 4215 is loosely fitted with the second shaft core 430 to enable the second end 422 of the first connecting rod to be rotatably connected to the second shaft core 430. The first end 441 of the second connecting rod may have a third connecting hole 4413 extending along the second direction X, and the third connecting hole 4413 is loosely fitted with the second shaft core 430 to enable the first end 441 of the second connecting rod to be rotatably connected to the third shaft core. The second end 442 of the second connecting rod may have a first guide column 4415 protruding in the second direction X. The first guide column 4415 may be slidably engaged with the lifting slot 310 to enable the second end 442 of the second connecting rod to be slidably connected to the lifting slot 310.

[0135] In the embodiment of the present application, there is no specific limitation on the number of first connecting rods 420 and second connecting rods 440. For example, as shown in FIG15 , there can be one first connecting rod 420 and two second connecting rods 440. One of the second connecting rods 440 is slidably connected to the lifting groove 310 of the first lifting member 300 c, and the other second connecting rod 440 is slidably connected to the lifting groove 310 of the second lifting member 300 d.

[0136] Figure 16 is a cross-sectional view of the assembly structure along section line AA in Figure 13 . Referring to Figures 13 and 16 , the base 100 may include a sliding hole 160 extending along the first direction Y. The sliding hole 160 is located on the side of the guide groove 170 away from the first arcuate 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 groove 310. Exemplarily, the first support plate of the base 100 may include a first bent portion 101c extending along the second direction X, and the second support plate of the base 100 may include a second bent portion 101d extending along the second direction X. The first bent portion 101c and the second bent portion 101d are stacked so that the first bent portion 101c and the second bent portion 101d together enclose the sliding hole 160. The number of the sliding holes 160 can be the same as the number of the second connecting rods 440. In an embodiment where there are two second connecting rods 440, the number of the sliding holes 160 defined by the first bent portion 101c and the second bent portion 101d can also be two. With the above arrangement, the second connecting rod 440 can be slidably connected relative to the base 100 along the first direction Y.

[0137] To sum up, when the flip bracket 200 rotates toward the lifting direction Z (the rotation direction can be the clockwise direction shown in Figure 12), the flip bracket 200 also drives the first axis core 410 to move along the first direction Y (the moving direction can be to the left direction shown in Figure 12), and the first axis 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 axis 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 slot 310 of the lifting bracket 300, and the lifting bracket 300 rotates in the lifting direction Z driven by the second connecting rod 440.

[0138] In some embodiments, referring to FIG14 , the base 100 may further include a guide groove 170 extending parallel to the first direction Y. For example, the guide groove 170 may be located on a side of the first arcuate chute 110 away from the mating chute 180. There may be two guide grooves 170, one located on the first extension 101a of the first support member 100a, and the other located on the second extension 101b of the second support member 100b. The second shaft core 430 is slidably connected to the guide groove 170, which helps further ensure that the second connecting rod 440 moves along the first direction Y when the flip bracket 200 rotates relative to the base 100.

[0139] Figure 17 is an assembly diagram of a flip bracket, a sleeve, a first shaft core, and a first connecting rod according to an embodiment of the present application; Figure 18 is an exploded view of another lifting mechanism according to an embodiment of the present application. Referring to Figures 17 and 18, in some embodiments, the lifting mechanism 10 may further include a sleeve 700. In conjunction with Figure 8, the first end 710 of the sleeve is sleeved on the first shaft core 410 and is rotatably connected to the first shaft core 410. The first end 710 of the sleeve is in an interference fit with the first shaft core 410, and the second end 720 of the sleeve is in a sliding connection with the base 100 in a direction perpendicular to the first axis L1. Here, "interference fit" refers to an interference fit or a fit that generates torque or friction. For example, the first end 710 of the sleeve may have a mating hole 711 extending along the second direction X. The mating hole 711 is in an interference fit with the first shaft core 410, thereby creating an interference fit between the first end 710 of the sleeve and the first shaft core 410. The second end 720 of the sleeve may have two second guide posts 721 protruding in the second direction X.

[0140] Accordingly, the base 100 further includes a mating groove 180. The mating groove 180 may extend perpendicular to the first axis L1, and the distance between the mating groove 180 and the second surface N2 decreases as it approaches the first axis L1. There may be two mating grooves 180, one located on the first extension 101a of the first support member 100a, and the other located on the second extension 101b of the second support member 100b. The second guide post 721 may slidably engage with the mating groove 180, thereby slidably connecting the second end 720 of the sleeve to the mating groove 180.

[0141] Through the above arrangement, during the rotation of the flip bracket 200 relative to the base 100, the second end 720 of the sleeve slides within the mating groove 180. Providing the mating groove 180 at an angle relative to the second surface N2 facilitates extending the length of the mating groove 180 within a limited space, thereby increasing the rotation angle of the flip bracket 200 relative to the base 100. Simultaneously, the interference fit between the first end 710 of the sleeve and the first shaft core 410 provides torque, enabling the flip bracket 200 to maintain the desired opening and closing angle during rotation relative to the base 100, and allowing the support housing 92 to stably support the electronic device 1, preventing the electronic device 1 from tipping over.

[0142] FIG19 is a structural diagram of a lifting mechanism provided in an embodiment of the present application, omitting a portion of the lifting bracket and a portion of the second connecting rod; FIG20 is a structural diagram of an elastic member provided in an embodiment of the present application. Referring to FIG19 , in some embodiments, the lifting mechanism 10 may further include an elastic member 800, wherein a first end 810 of the elastic member may be connected to the base 100, and a second end 820 of the elastic member may be connected to the lifting bracket 300. For example, in conjunction with FIG14 , an end of the first lifting member 300c away from the second axis 430 is bent toward the second lifting member 300d to form a first enclosure 301a, and an end of the second lifting member 300d away from the second axis 430 is bent toward the first lifting member 300c to form a second enclosure 301b. The first enclosure 301a and the second enclosure 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 may be connected to the first bending portion 101c and / or the second bending portion 101d, and the second end of the elastic member 800 may be connected to the first enclosing portion 301a and / or the second enclosing portion 301b.

[0143] When the lifting mechanism 10 is in a closed state, the elastic member 800 is in a first state. When the lifting mechanism 10 is in an open state, the elastic member 800 is in a second state, and the deformation of the elastic member 800 in the second state is different from the deformation of the elastic member 800 in the first state. It can be understood that in order to ensure smooth movement between the sliding fit and the rotational fit in the above embodiment, the shaft holes are usually clearance fit, and there is also usually a gap between the slide groove and the slider. However, the superposition of multiple gaps may cause the lifting mechanism 10 to shake when it moves. Through the above arrangement, when the deformation of the elastic member 800 of the lifting mechanism 10 is large, the elastic restoring force of the elastic member 800 is large. When the elastic restoring force of the elastic member 800 acts on the lifting mechanism 10, the lifting bracket 300 is pressed relative to the base 100 in the direction close to or away from the second surface N2, which is conducive to reducing the fitting gap between the lifting bracket 300 and other structural members 93, and avoiding shaking when the lifting mechanism 10 moves.

[0144] For example, when the deformation of the elastic member 800 in the second state is greater than the deformation of the elastic member 800 in the first state, when the lifting mechanism 10 is in the open state, it is helpful to reduce the matching clearance between the lifting bracket 300 and other structural members 93, thereby preventing shaking during the movement of the lifting mechanism 10. Alternatively, when the deformation of the elastic member 800 in the second state is less than the deformation of the elastic member 800 in the first state, when the lifting mechanism 10 is in the closed state, it is helpful to reduce the matching clearance between the lifting bracket 300 and other structural members 93, thereby preventing shaking during the movement of the lifting mechanism 10.

[0145] FIG20 is a structural diagram of an elastic member provided in an embodiment of the present application, wherein FIG20(a) is a structural diagram of the elastic member 800 in a first state, and FIG20(b) is a structural diagram of the elastic member 800 in a second state. In conjunction with FIG20 , 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 closer to or away from the second surface N2. When the lifting mechanism 10 is in a closed state, a first spacing is provided between the first plate portion 811 and the second plate portion 821. When the lifting mechanism 10 is in the open state, a second distance H2 is defined between the first plate portion 811 and the second plate portion 821 , and the second distance H2 is greater than the first distance.

[0146] For example, when the lifting mechanism 10 is in a closed state, the first plate portion 811 can be coplanar with the second plate portion 821, and the first spacing is zero in the lifting direction Z. When the lifting mechanism 10 is in an open state, the second plate portion 821 is closer to the first surface N1 relative to the first plate portion 811, and the second spacing H2 is greater than the first spacing in the lifting direction Z. 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 helps to reduce the matching clearance between the lifting bracket 300 and other structural components 93, thereby preventing shaking of the lifting mechanism 10 during movement.

[0147] In some other embodiments, the elastic member 800 may also be a torsion spring or a spring, etc., which can reduce the fitting clearance between the lifting bracket 300 and other structural members 93 .

[0148] In some embodiments, the lifting mechanism 10 may be symmetrically arranged, or the lifting mechanism 10 may be arranged on one side. For example, the base 100 may include only one of the first support member 100a and the second support member 100b, and the lifting bracket 300 may include only one of the first lifting member 300c and the second lifting member 300d. Accordingly, the number of the second connecting rod 440 may be only one.

[0149] Figure 21 is an exploded view of the structure of another electronic device provided in an embodiment of the present application; Figure 22 is an assembly structure diagram of a heat dissipation housing and a lifting mechanism provided in an embodiment of the present application. Referring to Figures 21 and 22, in another shell 90 of an embodiment of the present application, the shell 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, and the connecting plate 101 has a through hole. The heat dissipation housing 91 may also have a matching through hole, and the rotating shaft is provided in 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 embodiments, and will not be repeated here.

[0150] FIG23 is a partial enlarged view of the assembly structure in FIG22 at position M. In conjunction with FIG23 , the housing 90 further includes another lifting mechanism 10, which can be located between the structural member 93 and the heat dissipation housing 91. The lifting mechanism 10 can include a driving member 191 and a push block 192. The driving member 191 can be connected to the structural member 93, and the push block 192 can be connected to the driving member 191.

[0151] Figure 24 is a partial enlarged view of the heat dissipation housing at position M in Figure 22; Figure 25 is a structural diagram of a first lifting mechanism provided in an embodiment of the present application. Referring to Figures 24 and 25, push block 192 has a first inclined surface 1917, and the side of heat dissipation housing 91 facing structural member 93 has a second inclined surface 9133 that mates with first inclined surface 1917. When lifting mechanism 10 transitions between the closed and open states, driver 191 drives push block 192 in a direction parallel to structural member 93 (e.g., direction C1 or C2 in Figure 23).

[0152] In some embodiments, the driving member 191 can perform linear reciprocating motion within a certain range. Since the driving member 191 is connected to the push block 192, the driving member 191 can drive the push block 192 to move in a direction parallel to the structural member 93. For example, the driving member 191 can be a cylinder, the push rod of the cylinder is connected to the push block 192, and the push rod of the cylinder is parallel to the structural member 93.

[0153] With the above arrangement, when the push block 192 moves in a direction parallel to the structural member 93 (e.g., direction C1 in FIG. 23 ), the first inclined surface 1917 moves in a direction parallel to the structure, causing the second inclined surface 9133 to slide relative to the first inclined surface 1917, thereby opening the heat dissipation housing 91 relative to the structural member 93, increasing the airflow between the heat dissipation housing 91 and the structural member 93, and facilitating improved heat dissipation efficiency of the electronic device 1. When the push block 192 moves in a direction parallel to the structural member 93 and in the opposite direction (e.g., direction C2 in FIG. 23 ), the heat dissipation housing 91 closes relative to the structural member 93.

[0154] In some embodiments, referring to FIG. 25 , the drive member 191 may include a drive motor and a screw 1913. The drive shaft of the drive motor is connected to the screw 1913, which is threadedly connected to the push block 192. Based on the above structure, the drive shaft of the drive motor drives the screw 1913 to rotate. The screw 1913 can be arranged parallel to the structural member 93. The push block 192, which is threadedly connected to the screw 1913, moves along the extension direction of the screw 1913. 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, thereby increasing the airflow between the heat dissipation housing 91 and the structural member 93, and facilitating improved heat dissipation efficiency of the electronic device 1.

[0155] In some embodiments, a circuit board 193 may be further included, and the circuit board 193 is electrically connected to the drive motor. Furthermore, the circuit board 193 may be electrically connected to the mainboard of the electronic device 1. The mainboard of the electronic device 1 may include control software, which controls the movement of the drive motor.

[0156] In some embodiments, a data acquisition device may also be included. For example, the data acquisition device may include a temperature sensor, which may be electrically connected to the mainboard of the electronic device 1. When the temperature of the electronic device 1 reaches a preset temperature, the mainboard of the electronic device 1 controls the drive motor to move, causing the heat dissipation housing 91 to open relative to the structural member 93.

[0157] Based on the above structure, the shell 90 may include a supporting shell 92, or the shell 90 may also omit the supporting shell 92. In the embodiment in which the shell 90 includes the supporting shell 92, the supporting shell 92 is rotatably connected to the structural member 93. The data acquisition device may further include a Hall magnet sensor, which may be electrically connected to the mainboard of the electronic device 1, and the Hall magnet sensor includes a first magnetic body and a second magnetic body, the first magnetic body being connected to the supporting shell 92, and the second magnetic body being connected to the structural member 93. When the supporting shell 92 is closed relative to the structural member 93, the mainboard of the electronic device 1 controls the driving motor to move so that the heat dissipation shell 91 is closed relative to the structural member 93. When the supporting shell 92 is opened relative to the structural member 93, the mainboard of the electronic device 1 controls the driving motor to move so that the heat dissipation shell 91 is opened relative to the structural member 93.

[0158] The lifting mechanism 10 comprising the driving member 191 and the pushing block 192 is referred to as a first lifting mechanism 10a. A second lifting mechanism 10b may be further included between the support housing 92 and the structural member 93.
