Description

Technical Field

[0001] The present application relates to the field of electronic equipment, and in particular to an electronic equipment. Background Art

[0002] Electronic devices typically have high heat dissipation requirements. For example, laptop computers have a fan or other ventilation mechanism installed inside the keyboard housing, discharging air through openings on the side of the keyboard housing. However, to maintain the aesthetics of the electronic device, the opening size needs to be reduced. However, small openings have poor airflow and cannot meet the heat dissipation requirements. Enlarging the opening size to address both airflow and heat dissipation requirements may expose the electronic device's internal components, reducing its aesthetics. Summary of the Invention

[0003] The embodiments of the present application provide an electronic device that solves the problem that current electronic devices cannot achieve both good air outlet effects and high aesthetics.

[0004] To achieve the above objectives, an embodiment of the present application provides an electronic device comprising a first structural member, a second structural member, a transmission assembly, and a baffle. The first structural member is movably connected to the second structural member and is movable relative to the second structural member between a closed position and an extended extreme position. The first structural member further has an intermediate position between the closed position and the extended extreme position. The baffle is movably connected to the second structural member. Such movable connection methods include, but are not limited to, rotational connections and sliding connections. The baffle is transmission-connected to the first structural member via the transmission assembly at least when the first structural member is between the closed position and the intermediate position. The first structural member is capable of driving the baffle from a shielding position to an open position when moving from the closed position to the intermediate position. When the baffle needs to move from the open position to the shielding position, this can be achieved by moving the first structural member from the intermediate position to the closed position, or by manually moving the baffle. The second structural member is provided with a hollow portion. When the baffle is in the open position, the area of ​​the hollow portion blocked by the baffle is larger than the area of ​​the hollow portion blocked by the baffle when in the shielding position. At least a limiting structure is provided on the transmission assembly, and the limiting structure can also be provided on the first structural member or the second structural member. The limiting structure can limit the baffle to the open position when the first structural member moves between the intermediate position and the expansion limit position.

[0005] When the electronic device is not in use, the first structural member is in a closed position and the baffle is in a shielding position, thereby improving the aesthetics of the electronic device when not in use. When the electronic device is in use, the baffle can reach an open position when the first structural member is in a position intermediate between the closed position and the extended limit position. As the opening of the first structural member increases, the baffle does not open further due to the restraint of the limit structure. In this way, during normal use, the position of the baffle can meet the airflow requirements of the hollow portion while also shielding the hollow portion within a certain viewing angle, thereby achieving a balance between heat dissipation and aesthetics when the electronic device is in use.

[0006] As some possible implementations, the transmission assembly includes a first transmission member and a second transmission member, the first transmission member being connected to the first structural member, the second transmission member being connected to the second structural member, and the baffle being transmission-connected to the second transmission member. When the first structural member moves between the closed position and the intermediate position, the first transmission member is transmission-connected to the second transmission member. When the first structural member moves between the intermediate position and the extended limit position, the first transmission member is transmission-disconnected to the second transmission member. Thus, when the first structural member is between the intermediate position and the extended limit position, the second transmission member is no longer subjected to the force exerted by the first transmission member, and the limiting structure only needs to maintain the current open position of the baffle, thereby reducing wear on the second transmission member.

[0007] As some possible implementation methods, the limiting structure includes at least a first limiting portion and a second limiting portion, the first limiting portion is arranged on the first transmission member or the first structural member, and the second limiting portion is arranged on the second transmission member. When the first structural member is between the intermediate position and the expansion limit position, the first limiting portion can limit the movement of the second limiting portion. In this way, the limiting structure can limit the second transmission member by limiting the second limiting portion by the first limiting portion, thereby limiting the baffle. The first limiting portion and the second limiting portion are respectively arranged on the first transmission member and the second transmission member, which is convenient for detection, maintenance and replacement, and simplifies the installation process. When the limiting structure is worn or stuck, only the transmission component needs to be replaced, and there is no need to replace the first structural member and the second structural member. It is convenient, fast and cost-effective. At the same time, the appropriate first limiting portion and second limiting portion can be replaced according to actual needs.

[0008] As some possible implementation methods, when the first structural member moves between the intermediate position and the expansion limit position, the first limiting portion is slidably connected to the second limiting portion. In this way, when the first structural member rotates from the closed position through the intermediate position toward the expansion limit position, the first limiting portion can achieve a sliding connection with the second limiting portion without changing the motion state and the connection state with the first transmission member. The transition is smooth, avoiding the impact and vibration that may be caused by sudden braking, and reducing the wear between the first limiting portion and the second limiting portion. At the same time, the first limiting portion can accurately limit the second limiting portion from stopping movement by slidingly connecting with the second limiting portion, thereby achieving accurate positioning of the second transmission member. The composition and coordination method of the limiting structure are simple, do not rely on a complex electronic control system, are less affected by the environment, have high reliability, and have good repeatability.

[0009] As some possible implementations, the first transmission member includes a first shaft fixedly connected to the first structural member and a first transmission structure connected to the first shaft, a first limiting portion is disposed on the first shaft or the first structural member, and the second transmission member includes a second shaft rotatably connected to the second structural member and a second transmission structure connected to the second shaft, a second limiting portion is disposed on the second shaft, and the second limiting portion forms a limiting groove. When the first structural member moves between the closed position and the intermediate position, the first transmission structure is transmission-connected to the second transmission structure. When the first structural member moves between the intermediate position and the extended limit position, the first transmission structure is released from the transmission connection with the second transmission structure, and the first limiting portion is at least partially located within the limiting groove to limit the rotation of the second limiting portion in at least one direction. It should be noted that the second limiting portion is capable of forward and reverse rotation, and the first limiting portion can limit the forward rotation of the second limiting portion, limit the reverse rotation of the second limiting portion, or limit both forward and reverse rotation. In particular, the rotation direction of the second limiting portion when the first structural member moves from the closed position to the intermediate position can be defined as forward rotation. In this way, the position of the second limiting part can be accurately limited by sliding the first limiting part in the limiting groove, thereby achieving accurate positioning of the second limiting part. The structure is simple and the assembly is convenient. After the assembly is completed, it is only necessary to ensure that the first limiting part is at least partially located in the limiting groove when the second limiting part needs to be limited, thereby reducing the requirements for installation accuracy.

[0010] As some possible implementations, a first transmission structure includes a first rack disposed on a first shaft, the first rack extending circumferentially along the first shaft; and a second transmission structure includes a second rack disposed on a second shaft, the second rack extending circumferentially along the second shaft. When the first structural member moves between a closed position and an intermediate position, the first rack engages with the second rack, allowing the second transmission member to drive the baffle to move between a shielding position and an open position. When the first structural member moves between the intermediate position and the shielding position, the first rack separates from the second rack. The arrangement of the first and second racks facilitates assembly and provides high reliability.

[0011] In some possible implementations, the central angle corresponding to at least one of the first rack and the second rack is 60°-120°. During normal use, the user generally rotates the first structural member 90°-120°, at which point the baffle may already be in the open position to optimize heat dissipation of the electronic device, or the baffle may be close to the open position to achieve near-optimal heat dissipation of the electronic device.

[0012] As some possible implementations, the first limiting portion has a limiting surface, and the wall of the limiting groove has an arcuate cross-section. When the first structural member moves between the intermediate position and the extended limit position, the limiting surface can adapt to and slide relative to the wall of the limiting groove. In this way, regardless of the movement of the first limiting portion, the second limiting portion can remain in place, thus achieving dual restrictions on the forward and reverse rotation of the second limiting portion, thereby achieving accurate positioning of the baffle.

[0013] In some possible implementations, the first stopper has a stopper surface. When the first structural member moves from the closed position toward the extended limit position, the second stopper rotates in a positive direction. The first stopper is slidably connected to the positive-facing wall of the stopper slot via the stopper surface. Thus, when the first structural member is between the intermediate position and the extended limit position, the first stopper restricts the second stopper from rotating in the opposite direction.

[0014] As some possible implementations, the limiting structure further includes a third limiting portion disposed on the second structural member, the third limiting portion being configured to limit the baffle to the open position. The third limiting portion can be configured to limit forward rotation of the second limiting portion, thereby, in combination with the first limiting portion limiting reverse rotation of the second limiting portion, achieving bidirectional restriction of the second transmission member. The third limiting portion can also independently achieve bidirectional restriction of the second limiting portion. In other words, the provision of the third limiting portion can compensate for the insufficient position restriction of the second limiting portion by the first limiting portion, thereby improving the reliability of the baffle restriction.

[0015] In some possible implementations, the third limiter includes an elastic structure disposed on the second structural member. When the baffle is in the open position, the baffle or the second transmission member elastically engages with the elastic structure. This elastic structure is simple, easy to configure, and low-cost. It also facilitates the user's ability to manually reset the baffle to the shielding position. Thus, even when the electronic device is turned off and the first structural member has not yet been rotated to the closed position, the baffle can return to the shielding position to prevent the ingress of external dust.

[0016] As some possible implementations, the limiting structure further includes an elastic portion, wherein the first limiting portion is elastically connected to the first transmission member via the elastic portion; when the first structural member moves from the closed position toward the extended limit position, the second limiting portion rotates in the positive direction; when the first structural member is in the intermediate position, the first limiting portion elastically abuts against the second limiting portion and the second structural member to limit the reverse rotation of the second transmission member. In this way, the first limiting portion not only limits the second limiting portion, but also, when the user moves the first structural member from the intermediate position toward the extended limit position, the force to be applied by the user gradually increases due to the gradual increase in deformation of the elastic portion, thereby improving the operational feel and preventing the user from applying excessive force when the first structural member is close to the extended limit position without realizing it, resulting in excessive force on the first structural member when it reaches the extended limit position, causing damage to the first structural member.

[0017] As one possible implementation, the limiting structure includes a damping member disposed between the second transmission member and the second structural member to generate a damping force between the second transmission member and the second structural member. When the first structural member is between the intermediate position and the extended limit position, the baffle is stationary under the action of the damping force. This arrangement can reduce the number of components in the limiting structure and lower the requirements for installation precision.

[0018] As one possible implementation, as the first structural member moves from the closed position toward the intermediate position, the damping force generated by the damping member first increases and then decreases. Thus, when opening the first structural member, the user first increases the force to improve the operating feel and prevent accidental opening of the first structural member. The force is then reduced to facilitate user adjustment of the angle of the first structural member during use while preventing significant changes in damping force when the first structural member is rotated past the intermediate position.

[0019] As some possible implementations, the transmission assembly further includes a mounting member connected to the second structural member and defining a first mounting hole and a second mounting hole. The first shaft is rotatably connected to the first mounting hole, and the second shaft is rotatably connected to the second mounting hole. The transmission assembly enables the first structural member to be rotatably connected to the second structural member, eliminating the need for a separate rotating component. This reduces the number of structural members, facilitates assembly, and saves installation space.

[0020] As some possible implementations, the transmission assembly further includes a connector and a torsion structure. The connector includes a connecting portion and a plate portion. The connecting portion is connected to the first shaft and extends along the extension direction of the first shaft. The plate portion is connected to the connecting portion and is plate-shaped. The first structural member is connected to the plate portion. The torsion structure is connected to the first shaft and the first structural member and is used to provide torsion for the rotation of the first structural member. In this way, the transmission assembly can increase damping through the torsion structure, improve the operating feel of the first structural member, and prevent the first structural member from accidentally opening.

[0021] As some possible implementations, the second structural member includes a top plate, a bottom plate, and side plates. The top plate and the bottom plate are disposed opposite and spaced apart from each other. The side plates are connected to the periphery of the top plate and the bottom plate and, together with the top and bottom plates, form a mounting cavity. The hollow portion includes at least one air outlet opening formed in the side plate. The baffle covers the air outlet opening when in the shielding position. In this way, when the electronic device is not in use, the baffle prevents external dust and moisture from entering the mounting cavity.

[0022] As some possible implementations, the baffle has a connected rotating portion and a shielding portion, the rotating portion being rotatably connected to the second structural member, the shielding portion being used to shield the hollow portion when the baffle is in an upper shielding position, and the rotation angle of the baffle from the shielding position to the open position is less than or equal to 90°. When the angle between the shielding surface of the baffle and the plane where the solid portion forming the hollow portion is located (such as the back of the third side portion) is greater than 90°, the opening size of the baffle has basically no effect on the airflow out of the hollow portion, and the airflow out of the hollow portion is basically the same as when the angle between the shielding surface of the baffle and the plane where the solid portion forming the hollow portion is located is 90°. At the same time, when the shielding portion of the baffle is rotated upward, an angle greater than 90° can easily cause the baffle to affect the rotation of the first structural member toward the extended limit position.

[0023] As some possible implementations, the transmission assembly also includes a rod chain, which includes at least a first rod and a second rod, one end of the first rod is fixedly connected to the second transmission member, and the two ends of the second rod are respectively rotatably connected to the other end of the first rod and the shielding part. In this way, the second transmission member is connected to the shielding part through the first rod and the second rod in turn. When the second transmission member rotates, the first rod pushes or pulls the second rod to move, and the second rod pushes or pulls the shielding part to rotate relative to the rotating part, thereby realizing the rotation of the baffle. This multi-rod structure can bypass some obstacles, has a certain degree of flexibility, and can adapt to different spatial layouts and movement requirements to a certain extent. In addition, when the baffle is suddenly subjected to force, this multi-rod structure can absorb part of the impact force, reduce the damage to the transmission assembly, thereby improving the stability and reliability of the system and extending the service life of the equipment. This connection method can achieve force transmission and amplification by reasonably designing parameters such as the length and angle of the rod.

[0024] As some possible implementations, the second structural member is provided with an arcuate slot, the rotating portion being slidably connected to the arcuate slot, with the rotation axis of the rotating portion coinciding with the corresponding central axis of the slot. This reduces the space occupied by the baffle during rotation, preventing interference with the installation of other components within the mounting cavity. Furthermore, when the baffle is in the open position, it can remain within the air outlet or protrude less from the air outlet, thereby improving the aesthetics of the electronic device, reducing the risk of bumps to the baffle, and enhancing its reliability.

[0025] As some possible implementation methods, the first structural member has an installation cavity, and the hollow portion is connected to the installation cavity. When the baffle moves from the shielding position to the open position, the shielding portion moves away from the installation cavity to avoid the movement of the shielding portion occupying the cavity space of the installation cavity.

[0026] As some possible implementations, when the baffle is in the shielding position, the rotating portion is located on a side of the shielding portion near the first structural member. Thus, when the user flips the first structural member over for use, the shielding portion rotates upward. When the electronic device is in use, the baffle is located above the hollow portion, with air flowing horizontally or diagonally downwardly from the hollow portion under the guidance of the shielding surface. The user's height is higher than the second structural member. Therefore, the baffle can block the user's view of the hollow portion, thereby improving the aesthetics of the electronic device.

[0027] As some possible implementations, a display screen is provided on the first structural member, and a keyboard is provided on the second structural member. The electronic device is a notebook computer, and the notebook computer can take into account both aesthetics and heat dissipation by providing the transmission assembly and the baffle.

[0060] Figure 1 This is a three-dimensional structural diagram of an electronic device provided in an embodiment of the present application. Figure 2 for Figure 1 A cross-sectional view of the electronic device at AA. Figure 1 and Figure 2As shown, an embodiment of the present application provides an electronic device comprising a first structural member 10 and a second structural member 20 that are articulated. The articulation methods include, but are not limited to, rotational and sliding connections. In this electronic device, at least the housing of the second structural member 20 defines a mounting cavity 201. A control device 91 is disposed within mounting cavity 201. This control device 91 is used to control the electronic device to implement certain functions. This control device 91 includes, but is not limited to, chips, circuit boards, and electronic components. Chips include, but are not limited to, system-on-chips (SoCs), central processing units (CPUs), graphics processing units (GPUs), universal flash storage (UFS) chips, basic input / output system chips (BIOSs), and intelligent algorithm chips. Circuit boards include, but are not limited to, rigid circuit boards and flexible printed circuits (FPCs). Electronic components include, but are not limited to, resistors, capacitors, inductors, potentiometers, electron tubes, heat sinks, electromechanical components, connectors, discrete semiconductor devices, laser devices, optoelectronic devices, sensors, switches, micromotors, electronic transformers, relays, speakers, microphones, cameras, antennas, and the like. Each electronic component can be independently configured and communicatively connected to a circuit board or chip, or combined with the circuit board and / or chip to form a functional module. The specific configuration method can be determined based on usage requirements.

[0061] Among them, the control device 91 will generate heat during use, and the heat accumulated in the installation cavity 201 will affect the performance of the control device 91. Therefore, it is necessary to open an air outlet 202 connected to the installation cavity 201 on the casing of the electronic device, so that the heat in the installation cavity 201 can be discharged through the air outlet 202.

[0062] Figure 3 It is a three-dimensional structural diagram of current related electronic equipment. Figure 3 As shown, the size of the air outlet 202 in the electronic device housing (e.g., the second structural member 20) directly affects the electronic device's aesthetics and airflow efficiency. Larger air outlet 202, while still meeting the electronic device's airflow efficiency and heat dissipation requirements, may expose the device's internal components, reducing its aesthetics. On the other hand, smaller air outlet 202, while improving the device's aesthetics, may result in poor airflow efficiency and fail to meet its heat dissipation requirements. Therefore, current electronic devices cannot achieve both optimal airflow efficiency and high aesthetics.

[0063] To address the aforementioned issues, embodiments of the present application provide an electronic device that utilizes air outlets 202 to dissipate heat when in use, thereby meeting the electronic device's heat dissipation requirements. When not in use, at least a portion of air outlets 202 is shielded to improve aesthetics. The electronic device may be a laptop, a convertible tablet, an ultra-mobile personal computer (UMPC), a netbook, or an in-vehicle device.

[0064] For ease of description, in the following embodiments, the electronic device is described as a laptop computer. Figure 4 This is a three-dimensional structural diagram of the electronic device in some embodiments of the present application in the use state. Figure 4 As shown, the first structural member 10 is rotatably connected to the second structural member 20. The rotatable connection methods include, but are not limited to, hinges, bearing connections, spline connections, coupling connections, etc. The first structural member 10 rotates about its rotation axis. The rotation axis of the first structural member 10 can be located on the rotation axis of a physical shaft or a virtual axis, without limitation. A virtual axis refers to the rotation axis of an axis that does not exist in an actual physical entity and is simulated through design or technology.

[0065] For a laptop computer, the first structural member 10 may optionally include a display side housing 10a on which a display screen 93 may be provided, and the second structural member 20 may optionally include a keyboard 94 side housing 20a on which a keyboard 94 may be provided.

[0066] The first structural member 10 and the second structural member 20 are both plate-shaped. The first structural member 10 has a display surface 10a1 and a top surface 10a2 facing each other. The display screen 93 is disposed on the display surface 10a1 side of the first structural member 10. The second structural member 20 has a mounting surface 20a1 and a bottom surface 20a2 facing each other. The keyboard 94 is located on the mounting surface 20a1 side of the second structural member 20. The first structural member 10 and the second structural member 20 each have opposing first and second ends. The first end of the first structural member 10 is rotatably connected to the first end of the second structural member 20. In other embodiments, the first end of the first structural member 10 may also be rotatably connected to the middle portion of the second structural member 20, which is not a limitation here.

[0067] Figure 5 is a perspective view of an electronic device in an embodiment of the present application, wherein the first structural member is in a closed position; Figure 6 for Figure 5 The electronic device is in a cross-sectional view at BB. The keyboard 94 side housing 20a is formed with a mounting cavity 201 and an air outlet 202 connected to the mounting cavity 201. The mounting cavity 201 is provided with a control device 91, a keyboard 94 (combined with Figure 4 ) and the display screen 93 are both connected to the control device 91. The user can input instructions to the control device 91 through the keyboard 94, and the control device 91 can control the display screen 93 (combined with the control device 91) according to the instructions. Figure 4 ) to display images or control the functional components therein to execute relevant instructions. To improve heat dissipation efficiency, a fan 92 may be provided within the mounting cavity 201. The housing is further provided with an air inlet 203 connected to the mounting cavity 201. Driven by the fan 92, air can enter the mounting cavity 201 through the air inlet 203 and exchange heat with heat-generating components such as the control device 91, forming a hot air flow. The hot air flow is then discharged from the mounting cavity 201 through the air outlet 202, thereby achieving heat dissipation for the electronic equipment.

[0068] When the electronic device is in use, the second structural member 20 is placed on a tabletop, with the bottom surface 20a2 of the second structural member 20 resting against the tabletop. The mounting surface 20a1 of the second structural member 20 faces upward, while the bottom surface 20a2 faces downward. The vertical direction corresponds to the thickness of the second structural member 20. The first end of the second structural member 20 is located at the rear of the second structural member 20, and the second end of the second structural member 20 is located at the front of the second structural member 20. The two extending ends of the rotation axis of the first structural member 10 extend to the left and right, respectively. It should be noted that the spatial orientation of the electronic device described in the following embodiments is consistent with the spatial orientation of the second structural member 20.

[0069] Figure 7 : is a three-dimensional structural diagram of the electronic device in some embodiments of the present application, wherein the first structural member is in the extended extreme position. Figure 5 and Figure 7As shown, the first structural member 10 is capable of rotating between a closed position and an extended limit position. Specifically, when the electronic device is not in use, the first structural member 10 is in the closed position, which can be selected as the position where the first structural member 10 and the second structural member 20 are engaged. In this position, the display screen 93 on the first structural member 10 faces the keyboard 94 on the second structural member 20. The display surface 10a1 of the first structural member 10 can be positioned against the mounting surface 20a1 of the second structural member 20, and the display surface 10a1 and the mounting surface 20a1 are parallel, i.e., the angle between the display surface 10a1 and the mounting surface 20a1 is 0°. When the electronic device is to be used, the front end of the first structural member 10 can be rotated upward and flipped backward until the first structural member 10 reaches the extended limit position, where it cannot rotate or is not required. The angle of rotation of the first structural member 10 from the closed position to the extended limit position can be greater than or equal to 120° and less than or equal to 360°. When the user has finished using the electronic device, the first structural member 10 can be rotated back to the closed position. That is, the first structural member 10 is movable relative to the second structural member 20 between a closed position and an extended limit position. When a user is viewing the display screen 93, the first structural member 10 can be located in the extended limit position or between the closed position and the extended limit position. The angle between the display surface 10a1 of the first structural member 10 and the mounting surface 20a1 of the second structural member 20 can be used to represent the opening of the first structural member 10. A larger angle indicates a larger opening of the first structural member 10, and a smaller angle indicates a smaller opening of the first structural member 10.

[0070] Generally, for a laptop computer, when the first structural member 10 is at the maximum unfolding angle, the angle between the display surface 10a1 of the first structural member 10 and the mounting surface 20a1 of the second structural member 20 is 180°. When the user is viewing the display screen 93, the angle between the display surface 10a1 of the first structural member 10 and the mounting surface 20a1 of the second structural member 20 is generally between 90° and 180° (e.g., Figure 4 In other embodiments, when the first structural member 10 is in the closed position, the angle between the display surface 10a1 of the first structural member 10 and the mounting surface 20a1 of the second structural member 20 may also be a specific angle greater than 0°, which is not limited here.

[0071] like Figure 6 and Figure 7As shown, the second structural member 20 is provided with a hollow portion 21. The second structural member 20 uses this hollow portion 21 to allow air to escape from the installation cavity 201, thereby dissipating heat from the control device 91 within the installation cavity 201. The hollow portion 21 may have a hole structure, a slot structure, a notch structure, a grille structure, a louver structure, a heat sink structure, a honeycomb structure, or the like, as long as it can ventilate the accommodating cavity. In some embodiments, the hollow portion 21 includes, but is not limited to, at least one air outlet 202. When the hollow portion 21 has multiple air outlets 202, the multiple air outlets 202 may be arranged in an array or an irregular arrangement, without limitation. The multiple air outlets 202 may form a grid-like structure, a pattern structure, an array structure, or the like in the solid portion forming the hollow portion 21. The cross-sectional shape of the air outlet 202 includes, but is not limited to, square, circular, semicircular, fan-shaped, elliptical, regular polygonal, or irregular shapes, without limitation. The cross-sectional shape of the air outlet 202 refers to the cross-sectional shape perpendicular to the direction in which the air outlet 202 is opened. The airflow in the installation cavity 201 can flow out of the air outlet 202 along the opening direction of the air outlet 202, that is, the opening direction of the air outlet 202 is the outlet direction of the air outlet 202. The solid parts forming the hollow portion 21 can be located on the same plane or not, and this is not limited here.

[0072] Figure 8 FIG. 1 is a partial exploded view of an electronic device in an embodiment of the present application, wherein the baffle is in a shielding position. Figure 8 As shown, in this embodiment of the application, the electronic device further includes a transmission assembly 30 and a baffle 40. The electronic device drives the baffle 40 through the transmission assembly 30 to block or avoid the air outlet 202.

[0073] Specifically, the baffle 40 is movably connected to the second structural member 20, and the movably connected connection methods include but are not limited to rotational connection and sliding connection. When the first structural member 10 is between the closed position and the intermediate position, the baffle 40 is transmission-connected to the transmission assembly 30, and the transmission assembly 30 is transmission-connected to the first structural member 10. That is, the baffle 40 is transmission-connected to the first structural member 10 through the transmission assembly 30. The transmission assembly 30 may or may not be connected to the second structural member 20. In this case, the first structural member 10 and the second structural member 20 may be rotationally connected solely through the transmission assembly 30, or through other structural members independent of the transmission assembly 30, or through a combination of the transmission assembly 30 and other structural members, without limitation. The above transmission connection methods include but are not limited to mechanical transmission (such as belt drive, rod drive, chain drive, gear drive, worm drive, etc.), fluid transmission (such as hydraulic transmission, pneumatic transmission, etc.), electric transmission (such as direct click transmission, power electronic transmission, etc.), and magnetic transmission. When the first structural member 10 is between the intermediate position and the extended extreme position, the baffle 40 may still maintain a transmission connection with the first structural member 10 through the transmission assembly 30, or the baffle 40 may only maintain a transmission connection with the transmission assembly 30, while the transmission assembly 30 internally disconnects the transmission connection, or the transmission assembly 30 disconnects the transmission connection with the first structural member 10 or the second structural member 20, or the baffle 40 disconnects the transmission connection with the transmission assembly 30, but the transmission assembly 30 still maintains a transmission connection with the first structural member 10, and this is not limited here. The second structural member 20 may be connected to one baffle 40 or multiple baffles 40. When multiple baffles 40 are connected to the second structural member 20, some or all of the multiple baffles 40 may be transmission-connected to the same transmission assembly 30, or multiple transmission assemblies 30 may be provided, with each baffle 40 being transmission-connected to one or more transmission assemblies 30, and this is not limited here.

[0074] The baffle 40 can be made of a hard material, such as engineering plastics, metal, or composite materials. The baffle 40 can be a plate-like structure, wherein the baffle 40 has a shielding surface. When the baffle 40 is in the shielding position, the airflow from the hollow portion 21 hits the shielding surface. The shielding surface can be flat, curved, or folded, without limitation. In other embodiments, the baffle 40 can be composed of both hard and flexible materials. For example, the frame of the baffle 40 can be formed of a hard material, and the shielding surface of the baffle 40 can be formed of a flexible material.

[0075] Figure 9 This is a three-dimensional structural diagram of an electronic device provided in some embodiments of the present application, wherein the baffle is in an open position. Figure 8 and Figure 9As shown, the baffle 40 has an open position and a shielding position. The baffle 40 is movable between the open and shielding positions. The projected area of ​​the baffle 40 in the airflow direction of the hollow portion 21 is the shielding area of ​​the baffle 40 on the hollow portion 21. When the baffle 40 is in the open position, the shielding area of ​​the hollow portion 21 is greater than when the baffle 40 is in the shielding position. As can be understood, when the baffle 40 is in the open position, the shielding area of ​​the hollow portion 21 is a, and when the baffle 40 is in the shielding position, the shielding area of ​​the hollow portion 21 is b, where b is greater than a. Thus, when the baffle 40 is in the shielding position, it can shield all or part of the hollow portion 21, thereby improving the aesthetics of the electronic device. When the baffle 40 is in the open position, the shielding area of ​​the hollow portion 21 is reduced, thereby increasing the airflow and improving the airflow efficiency to meet heat dissipation requirements.

[0076] As Figure 9 In the illustrated embodiment, the solid portion forming the hollow portion 21 is located on the same plane, and the airflow direction of the hollow portion 21 is perpendicular to the plane in which the solid portion forming the hollow portion 21 is located. When the baffle 40 is in the shielding position, the baffle 40 covers the hollow portion 21. At this time, the shielding surface of the baffle 40 can be perpendicular to the airflow direction of the hollow portion 21, or it can be at an angle other than 90° to the airflow direction of the hollow portion 21, without limitation. When the baffle 40 is in the open position, the shielding surface of the baffle 40 can be parallel to the airflow direction of the hollow portion 21, or it can be set at an obtuse angle to the plane in which the solid portion forming the hollow portion 21 is located, so as to reduce or eliminate the obstruction of the airflow blown out of the hollow portion 21 by the baffle 40. The angle between the blocking surface of the baffle 40 and the plane on which the solid portion forming the hollow portion 21 is located can be used to represent the opening of the baffle 40. The larger the angle between the two, the larger the opening of the baffle 40, and the smaller the angle between the two, the smaller the opening of the baffle 40. In other embodiments, when the baffle 40 is in the shielding position, the baffle 40 does not completely cover the hollow portion 21. For example, the blocking surface of the baffle 40 and the plane on which the solid portion forming the hollow portion 21 is located form an angle greater than 0°, or the baffle 40 is engaged with the solid portion forming the hollow portion 21, that is, the angle between the blocking surface of the baffle 40 and the plane on which the solid portion forming the hollow portion 21 is located is 0°, but the baffle 40 avoids part of the hollow portion 21. This is not limited here, as long as the opening of the baffle 40 in the open position is greater than the opening of the baffle 40 in the shielding position.

[0077] Since the first structural member 10 is linked to the baffle 40 via the transmission assembly 30, the rotation of the first structural member 10 can drive the baffle 40 to move relative to the second structural member 20. When the first structural member 10 moves from the closed position to the extended limit position, the baffle 40 also moves from the shielding position to the open position. However, if the baffle 40 is configured to be in the shielding position when the first structural member 10 is in the closed position and in the open position when the first structural member 10 is in the extended limit position, then the baffle 40 will only move to the open position when the first structural member 10 is in the extended limit position. Under normal circumstances, the user will not rotate the first structural member 10 to the extended limit position, but will rotate the first structural member 10 to a position that is convenient for viewing or operation, which is generally located between the closed position and the extended limit position. Therefore, if the open position is set to just meet the heat dissipation requirements of the electronic device to avoid the baffle 40 being opened too wide in the open position, thereby affecting the aesthetics of the electronic device, then when the user is in normal use, the baffle 40 will not be able to reach the open position, but will be between the shielding position and the open position, thus failing to meet the heat dissipation requirements of the electronic device. In order to enable the opening of the baffle 40 to meet the heat dissipation requirements of the electronic device when the user is in normal use, the opening of the baffle 40 in the open position needs to be set larger, but this will result in the hollow portion 21 being exposed at a wider angle when the first structural member 10 is rotated to the expansion limit position, thereby causing the user to be able to see the structural members in the mounting cavity 201, thereby affecting the aesthetics of the electronic device.

[0078] Based on this, in the embodiment of the present application, a limiting structure is provided at least on the transmission assembly 30 . Figure 10 FIG. 1 is a three-dimensional structural diagram of an electronic device in some embodiments of the present application, wherein the first structural member is in the middle position. Figure 10 As shown, the first structural member 10 has an intermediate position, which is located between the closed position and the extended extreme position. The first structural member 10 must first pass through the intermediate position before reaching the extended extreme position. The first structural member 10 can drive the baffle 40 from the shielding position to the open position when moving from the closed position to the intermediate position. When the first structural member 10 moves between the intermediate position and the extended extreme position, the limiting structure can limit the baffle 40 to the open position. At this time, the first structural member 10 can release the transmission connection with the baffle 40, or it can still maintain the transmission connection. However, the baffle 40 is restricted from moving with the first structural member 10 by the limiting structure.

[0079] Thus, when the electronic device is not in use, the first structural member 10 is in the closed position and the baffle 40 is in the shielding position, thereby improving the aesthetics of the electronic device when not in use. When the electronic device is in use, the baffle 40 can reach the open position when the first structural member 10 is in a position intermediate between the closed position and the extended limit position. As the opening of the first structural member 10 increases, the opening of the baffle 40 does not continue to increase due to the restraint of the limiting structure. In this way, during normal use, the position of the baffle 40 can meet the airflow requirements of the hollow portion 21 while also shielding the hollow portion 21 within a certain viewing angle, thereby achieving both the heat dissipation effect and the aesthetics of the electronic device when in use.

[0080] The opening degree of the first structural member 10 when in the intermediate position can be greater than or equal to the opening degree of the first structural member 10 when the user is normally using the electronic device, to ensure that the baffle 40 is already in the open position when the user is normally using the electronic device, thereby achieving the maximum possible airflow rate of the hollow portion 21. Of course, in other embodiments, the opening degree of the first structural member 10 when in the intermediate position can also be less than the opening degree of the first structural member 10 when the user is normally using the electronic device. However, when the user is normally using the electronic device, the opening degree of the first structural member 10 is close to the opening degree of the first structural member 10 when in the intermediate position.

[0081] It should be noted that when the baffle 40 is in the open position and needs to be returned to the shielding position, this can be achieved by rotating the first structural member 10 from the middle position to the closed position to achieve automatic closing of the baffle 40, or it can be achieved by manually moving the baffle 40 to increase the freedom of operation, which is not limited here.

[0082] like Figure 10 As shown, in some embodiments, the second structural member 20 includes a top plate 22, a bottom plate 23 and a side plate 24. The top plate 22 and the bottom plate 23 are spaced apart and are arranged relative to each other in the thickness direction of the second structural member 20. The top plate 22 has a mounting surface 20a1 of the second structural member 20, and the bottom plate 23 has a bottom surface 20a2 of the second structural member 20. The side plates 24 are connected to the peripheral sides of the top plate 22 and the peripheral sides of the bottom plate 23, and are jointly enclosed with the top plate 22 and the bottom plate 23 to form a mounting cavity 201. The hollow portion 21 includes at least one air outlet 202 opened on the side plate 24, and the baffle 40 covers the at least one air outlet 202 when in the shielding position.

[0083] Optionally, the side panel 24 includes a first side portion, a second side portion 241, a third side portion 242, and a fourth side portion, which are sequentially connected end to end. The first side portion is located in front of the second structural member 20, the second side portion 241 is located on the left side of the second structural member 20, the third side portion 242 is located on the rear side of the second structural member 20, and the fourth side portion is located on the right side of the second structural member 20. The hollow portion 21 includes a plurality of air outlet holes 202, each of which is provided on the third side portion 242 and arranged in a sequential left-right direction. In this case, the third side portion 242 is the solid portion forming the hollow portion 21 and has a back surface facing away from the mounting cavity 201. A baffle 40 is provided. When in the shielding position, the baffle 40 can block all of the air outlet holes 202 in the front-to-back direction. In this case, the baffle 40 can abut against the back surface of the third side portion 242. Of course, when the baffle 40 is in the shielding position, the baffle 40 can also be at least partially accommodated in the air outlet 202. At this time, the edge of the baffle 40 can fit into the gap between the hole wall of the air outlet 202, and the baffle 40 and the back of the third side portion 242 can be against each other or spaced apart.

[0084] In other embodiments, the hollow portion 21 may also be provided on the bottom plate 23 and / or the top plate 22, and the air outlet 202 may also be provided on other sides of the baffle 40 except the third side portion 242, which is not limited here.

[0085] Figure 11 FIG. 1 is a partial exploded view of the electronic device in some embodiments of the present application. Figure 11As shown, in some embodiments, the baffle 40 includes a rotating portion 41 and a shielding portion 42 connected to each other. The rotating portion 41 is rotatably connected to the second structural member 20. The shielding portion 42 has a shielding surface 401 of the baffle 40. The rotation axis of the rotating portion 41 can be the axis of a solid shaft, and the rotating portion 41 can be shaft-shaped. When the rotating portion 41 rotates, the shielding portion 42 performs a circular motion around the rotation axis of the rotating portion 41. When the angle between the shielding surface 401 of the baffle 40 and the plane of the solid portion forming the hollow portion 21 (e.g., the back surface of the third side portion 242) is less than or equal to 90°, the larger the opening of the baffle 40, the smaller the area shielded by the baffle 40 from the hollow portion 21, and the greater the airflow from the hollow portion 21. The smaller the opening of the baffle 40, the larger the area shielded by the baffle 40 from the hollow portion 21, and the smaller the airflow from the hollow portion 21. When the angle between the shielding surface 401 of the baffle 40 and the plane where the solid part forming the hollow part 21 is located (such as the back of the third side portion 242) is greater than 90°, the opening size of the baffle 40 has basically no effect on the air outlet of the hollow part 21, and the air outlet of the hollow part 21 is basically the same as when the angle between the shielding surface 401 of the baffle 40 and the plane where the solid part forming the hollow part 21 is located is 90°. At the same time, when the shielding part 42 of the baffle 40 is rotated upward, an angle greater than 90° can easily cause the baffle 40 to affect the rotation of the first structural member 10 toward the expansion limit position. Therefore, the angle between the shielding surface 401 and the plane where the solid part forming the hollow part 21 is located when the baffle 40 is in the open position can be set to be less than or equal to 90°. It should be noted that, as the opening of the baffle 40 is larger, the user can see the hollow portion 21 from a wider angle, and thus can see the components in the installation cavity 201 through the hollow portion 21. The smaller the opening of the baffle 40 is, the smaller the angle at which the user can see the hollow portion 21, and thus the less the user can see the components in the installation cavity 201. Therefore, in actual applications, the opening position of the baffle 40 can be set according to the specific structure and design requirements of the electronic equipment.

[0086] Optionally, when the baffle 40 is in the shielding position, the shielding portion 42 abuts against the second structural member 20, specifically against the back surface of the third side portion 242. At this point, the angle between the baffle 40 and the plane of the solid portion forming the hollow portion 21 is 0°, and the baffle 40 rotates from the shielding position to the open position at an angle of 60°-90°. This allows the baffle 40 to effectively adjust the airflow volume and ensures a sufficiently high airflow volume when the baffle 40 is in the open position. At the same time, the hollow portion 21 is shielded as much as possible, minimizing the angle at which the user sees the hollow portion 21.

[0087] Optionally, when the baffle 40 is in the shielding position, the rotating portion 41 is located on the side of the shielding portion 42 closer to the first structural member 10, that is, the rotating portion 41 is located above the shielding portion 42. In this way, when the user flips over the first structural member 10 for use, the shielding portion 42 rotates upward. When the electronic device is in use, the baffle 40 is located above the hollow portion 21, and the hollow portion 21 discharges air horizontally or obliquely downward under the guidance of the shielding surface 401. The user's height is higher than the second structural member 20. Therefore, the baffle 40 can block the user's view of the hollow portion 21, thereby improving the appearance of the electronic device.

[0088] Optionally, when the baffle 40 moves from the shielding position toward the open position, the shielding portion 42 moves in a direction away from the mounting cavity 201, that is, the shielding portion 42 moves outward relative to the rotating portion 41 to avoid the movement of the shielding portion 42 occupying the cavity space of the mounting cavity 201.

[0089] Figure 12 For Figure 11 A partially enlarged view of the electronic device in another embodiment of the present application from the perspective of FIG. Figure 12 As shown, the baffle 40 optionally further includes a stopper 43 connected to the edge of the shielding portion 42. The stopper 43 can form a step structure with the shielding surface 401, with the shielding surface 401 protruding beyond the stopper 43 in the direction of its normal. When the baffle 40 is in the shielding position, the shielding portion 42 is at least partially contained within the air outlet 202, and the stopper 43 abuts against the back surface of the third side portion 242. In this way, the baffle 40 is restricted in the shielding position by the stopper 43, while also improving the sealing performance of the air outlet 202. The stopper 43 can be provided on the edge of the shielding portion 42 away from the rotating portion 41, or on the left and right edges of the shielding portion 42. This is not a limitation, as long as it can effectively restrict the shielding portion 42. It should be noted that when there are multiple air outlet holes 202 and one baffle 40 is used to block all air outlet holes 202 or more than two air outlet holes 202, the baffle 40 may have multiple blocking parts 42, each blocking part 42 corresponds to an air outlet hole 202, and accordingly, there are also multiple rotating parts 41, each blocking part 42 corresponds one-to-one to each rotating part 41, and the multiple blocking parts 42 are connected through a stop part 43.

[0090] The rotation axis of the rotating portion 41 may be not only the axis of the physical axis mentioned above, but also a virtual axis. Figure 12As shown, the second structural member 20 is optionally provided with an arcuate groove 204. The arcuate groove 204 can be provided on the wall of the air outlet 202, on the wall of the mounting cavity 201, or on an independent structure connected to the second structural member 20, without limitation. The rotating portion 41 is slidably connected to the arcuate groove 204, and the baffle 40 rotates by sliding along the arcuate groove 204 via the rotating portion 41. The rotation axis of the rotating portion 41 coincides with the central axis corresponding to the arcuate groove 204. In this way, the space occupied by the baffle 40 during rotation is reduced, avoiding interference with the installation of other components in the mounting cavity 201. At the same time, when the baffle 40 is in the open position, the baffle 40 can still be located in the air outlet 202, or protrude less from the air outlet 202, thereby improving the aesthetics of the electronic device, while reducing the impact on the baffle 40 and improving the reliability of the baffle 40. In other embodiments, the hole wall of the air outlet 202 may also be provided with a slide groove extending along a straight line, and the extension direction of the slide groove is the same as the opening direction of the air outlet 202. When the rotating part 41 rotates, it can also slide along the slide groove toward the installation cavity 201. There is no limitation here.

[0091] like Figure 11 and Figure 12 As shown, the baffle 40 may optionally further include a reinforcement portion 44 in the form of a rib. The reinforcement portion 44 may protrude from the shielding surface 401 of the shielding portion 42 to enhance the structural strength of the shielding portion 42 and prevent deformation of the baffle 40 when subjected to uneven force. Furthermore, being disposed inside the shielding portion 42 may prevent the baffle 40 from being aesthetically pleasing. When the baffle 40 has multiple shielding portions 42, the reinforcement portion 44 may also be disposed on the stop portion 43 between two adjacent shielding portions 42 to enhance the reliability of the stop portion 43 and prevent deformation of the baffle 40 at the stop portion 43. The reinforcement portion 44 may be disposed on the outside of the stop portion 43, i.e., on the side facing away from the shielding surface 401, to prevent interference between the stop portion 43 and the back surface of the third side portion 242.

[0092] Optionally, the reinforcing portion 44 is arranged on the shielding portion 42 and extends in a direction inclined at the rotating portion 41 to the shielding portion 42. It can be understood that the reinforcing portion 44 has a first extension end and a second extension end, the first extension end is close to the rotating portion 41, and the second extension end is away from the rotating portion 41. The angle between the extension direction of the reinforcing portion 44 and the rotation axis of the baffle 40 is an angle other than 90°, so as to achieve inclined guidance of the airflow out of the air outlet 202.

[0093] Figure 13 3D diagram of the electronic device in some embodiments of the present application. Figure 12 and Figure 13As shown, some electronic devices may be provided with a socket 205 on the second side 241 or the fourth side for connecting to an external communication device. In this case, the reinforcing portion 44 may be configured such that its second extending end extends in a direction away from the socket 205, thereby directing part of the airflow toward the side away from the socket 205. For example, when the second side 241 is provided with the socket 205, the first extending end of the reinforcing portion 44 is close to the second side 241 and away from the fourth side, while the second extending end of the reinforcing portion 44 is close to the fourth side and away from the second side 241.

[0094] In addition to the air outlet 202, the third side portion 242 of some electronic devices also has a socket 205 for connecting to external communication devices, such as Figure 13 As shown, a socket 205 is provided in the middle of the third side portion 242, and air outlets 202 are provided on both the left and right sides of the socket 205. In this case, the reinforcement portion 44 can be configured so that its second extension end extends away from the socket 205, thereby directing part of the airflow toward the side away from the socket 205. For example, when the air outlet 202 is provided on the left side of the socket 205, the second extension end of the reinforcement portion 44 on the left baffle 40 is located to the right of the first extension end of the reinforcement portion 44. In this way, the reinforcement portion 44 not only improves the structural strength of the baffle 40 but also reduces the amount of air blowing toward the external communication device, thereby preventing it from affecting its performance.

[0095] There are various ways to dispose the transmission assembly 30. For example, the transmission assembly 30 includes two transmission members disposed on the first structural member 10 and the second structural member 20, respectively. In this case, the limiting structure 60 can be disposed on at least one of the transmission members, or can also be disposed on the first structural member 10 or the second structural member 20. The transmission assembly 30 can also include only a transmission member disposed on the first structural member 10. In this case, the limiting structure 60 can be disposed on the transmission member, or can also be disposed on the first structural member 10 or the second structural member 20. The following embodiments illustrate the above-mentioned methods respectively.

[0096] Figure 14 FIG. 1 is a partial cross-sectional view of the electronic device in some embodiments of the present application. Figure 14As shown, in some embodiments, the transmission assembly 30 includes a first transmission member 31 and a second transmission member 32. The first transmission member 31 is connected to the first structural member 10, the second transmission member 32 is connected to the second structural member 20, and the baffle 40 is transmission-connected to the second transmission member 32. When the first structural member 10 moves between the closed position and the intermediate position, the first transmission member 31 is transmission-connected to the second transmission member 32. When the first structural member 10 moves between the intermediate position and the extended limit position, the first transmission member 31 is transmission-disconnected to the second transmission member 32. Thus, when the first structural member 10 is between the intermediate position and the extended limit position, the second transmission member 32 is no longer subjected to the force applied by the first transmission member 31. The retaining structure only needs to maintain the current open position of the baffle 40, reducing wear on the second transmission member 32.

[0097] The first transmission member 31 includes a first shaft 311 fixedly connected to the first structural member 10 and a first transmission structure 312 connected to the first shaft 311. The second transmission member 32 includes a second shaft 321 rotatably connected to the second structural member 20 and a second transmission structure 322 connected to the second shaft 321. The first transmission structure 312 and the second transmission structure 322 are in transmission connection with each other, and the baffle 40 is in transmission connection with the second shaft 321. When the first structural member 10 rotates, the first shaft 311 rotates with the rotation of the first structural member 10. When the first structural member 10 is between the closed position and the intermediate position, the first shaft 311 drives the second shaft 321 to rotate through the transmission connection between the first transmission structure 312 and the second transmission structure 322, and the second shaft 321 drives the baffle 40 to move between the shielding position and the open position. The first structural member 10 and the second structural member 20 are rotationally connected via the transmission assembly 30. The rotation axis of the first structural member 10 coincides with the central axis of the first shaft 311, and the rotation axis of the first shaft 311 is parallel to the rotation axis of the second shaft 321. In other embodiments, the rotation axis of the first shaft 311 may also be arranged at an angle to the rotation axis of the second shaft 321, such as a 90° angle. In this case, the first transmission structure 312 and the second transmission structure 322 may both be bevel gears.

[0098] In order to shield the first transmission member 31, a notch can be opened on the first structural member 10, and the first transmission member 31 can be set at the notch. Then, the first structural member 10 is covered by a shielding cover 50 and connected to the second structural member 20 to improve the aesthetics of the electronic device.

[0099] Optionally, the first transmission structure 312 includes a first rack 312a, which is disposed on the first shaft 311 and extends circumferentially around the first shaft 311. The circumferential direction of the first shaft 311 refers to a direction around the rotation axis of the first shaft 311. The second transmission structure 322 includes a second rack 322a, which is disposed on the second shaft 321 and extends circumferentially around the second shaft 321. The circumferential direction of the second shaft 321 refers to a direction around the rotation axis of the second shaft 321. When the first structural member 10 moves between the closed position and the intermediate position, the first rack 312a engages with the second rack 322a, allowing the second transmission member 32 to drive the baffle 40 between the shielding position and the open position. When the first structural member 10 moves between the intermediate position and the shielding position, the first rack 312a and the second rack 322a separate.

[0100] When the first structural member 10 moves from the closed position toward the intermediate position, the first shaft 311 drives the second shaft 321 to rotate through the engagement of the first rack 312a and the second rack 322a. At this time, the rotation of the second shaft 321 can be defined as forward rotation. When the first structural member 10 moves from the intermediate position toward the closed position, the rotation of the second shaft 321 can be defined as reverse rotation. The forward rotation of the second shaft 321 can drive the baffle 40 from the shielding position toward the open position, and the reverse rotation of the second shaft 321 can drive the baffle 40 from the open position toward the shielding position. It should be noted that the forward and reverse directions are clockwise and counterclockwise, respectively. As shown in the figure, the forward direction is clockwise and the reverse direction is counterclockwise.

[0101] Exemplarily, the central angle corresponding to the first rack 312a and the central angle corresponding to the second rack 322a are both 60°-120°, and the central angle corresponding to the first rack 312a and the central angle corresponding to the second rack 322a are the same. With this central angle s being the same, the rotation angle of the first structural member 10 from the closed position to the intermediate position is also s. During normal use, the user generally rotates the first structural member 10 90°-120°. At this point, the baffle 40 may already be in the open position to optimize the heat dissipation of the electronic device, or the baffle 40 may be close to the open position to optimize the heat dissipation of the electronic device. In the illustrated embodiment, the central angle corresponding to the first rack 312a and the central angle corresponding to the second rack 322a are both 90°, ensuring that the baffle 40 is in the open position when the electronic device is in normal use.

[0102] In other embodiments, the central angle corresponding to the first rack 312a and the central angle corresponding to the second rack 322a may also be different. In this case, the rotation angle of the first structural member 10 from the closed position to the intermediate position is the same as the smaller of the corresponding central angles of the first rack 312a and the second rack 322a. That is, when the central angle corresponding to the first rack 312a is smaller than the central angle corresponding to the second rack 322a, the rotation angle of the first structural member 10 from the closed position to the intermediate position is the same as the central angle corresponding to the first rack 312a. When the central angle corresponding to the first rack 312a is larger than the central angle corresponding to the second rack 322a, the rotation angle of the first structural member 10 from the closed position to the intermediate position is the same as the central angle corresponding to the second rack 322a. The first transmission structure 312 and the second transmission structure 322 may also be a turbine and a worm, a belt and a pulley, a chain and sprocket teeth, a screw and a nut, two rough surfaces, etc., without limitation herein.

[0103] like Figure 14 As shown, in some embodiments, the transmission assembly 30 further includes a rod chain 33 comprising at least a first rod 331 and a second rod 332. One end of the first rod 331 is fixedly connected to the second shaft 321, while both ends of the second rod 332 are rotatably connected to the other end of the first rod 331 and the shielding portion 42, respectively. In this manner, the second transmission member 32 is connected to the shielding portion 42 via the first rod 331 and the second rod 332, respectively. When the second shaft 321 rotates, the first rod 331 pushes or pulls the second rod 332 to move, which in turn pushes or pulls the shielding portion 42 relative to the rotating portion 41, thereby rotating the baffle 40. This multi-rod structure can circumvent obstacles, offers a certain degree of flexibility, and can adapt to different spatial layouts and movement requirements. Furthermore, when the baffle 40 is suddenly subjected to force, this multi-rod structure can absorb some of the impact force, reducing damage to the transmission assembly 30, thereby improving the stability and reliability of the system and extending the service life of the device. This connection method can achieve force transmission and amplification by rationally designing parameters such as rod length and angle.

[0104] In other embodiments, the rod chain 33 may include more than three rods in a transmission connection, which is not a limitation herein. The transmission assembly 30 may also achieve a transmission connection between the second transmission member 32 and the baffle 40 through other transmission structures, such as other mechanical transmissions (e.g., belt drives, chain drives, gear drives, worm drives, etc.), fluid transmissions (e.g., hydraulic transmissions, pneumatic transmissions, etc.), electric transmissions (e.g., direct click transmissions, power electronic transmissions, etc.), and magnetic transmissions, which are not a limitation herein.

[0105] Figure 15 A partial three-dimensional structural diagram of a transmission assembly in an electronic device of the present application in one embodiment; Figures 16 to 20It is a partial cross-sectional view of the electronic device in the embodiment of the present application at different opening degrees, wherein: Figure 16 The opening of the first structural member is 0°, Figure 17 The opening angle of the first structural member is 45°. Figure 18 The opening angle of the first structural member is 60°. Figure 19 The opening angle of the first structural member 10 is 90°. Figure 20 The opening of the first structural member is 180°. For the convenience of description, the opening of the first structural member 10 when it is in the middle position is 60°, that is, when the opening of the first structural member 10 is 60°, the baffle 40 is in the open position, and the opening of the baffle 40 is 90°. Figures 15 to 20 .

[0106] As one of the embodiments, the limiting structure 60 includes at least a first limiting portion 61 and a second limiting portion 62. The first limiting portion 61 is provided on the first transmission member 31. The first limiting portion 61 can be fixedly connected to the first transmission member 31, and can also move relative to the first transmission member 31 under the action of a certain external force, which is not limited here. The second limiting portion 62 is provided on the second transmission member 32. The second limiting portion 62 can be fixedly connected to the second transmission member 32, and can also move relative to the second transmission member 32 under the action of a certain external force, which is not limited here. The first limiting portion 61 can limit the movement of the second limiting portion 62. It can be understood that when the first structural member 10 moves from the closed position toward the middle position (such as Figure 16 ), the first transmission member 31 drives the second transmission member 32 to move, the first limiting member moves with the movement of the first transmission member 31, and the second limiting member moves with the movement of the second transmission member 32, and the first limiting portion 61 and the second limiting portion 62 do not interact with each other; when the first structural member 10 moves between the intermediate position and the extended limit position (such as Figure 19 ), the first limiting portion 61 can limit the movement of the second limiting portion 62. In this way, the limiting structure 60 can limit the second transmission member 32 by limiting the second limiting portion 62 by the first limiting portion 61, thereby limiting the baffle 40. The first limiting portion 61 and the second limiting portion 62 are respectively arranged on the first transmission member 31 and the second transmission member 32, which facilitates inspection, maintenance and replacement, and simplifies the installation process. When the limiting structure 60 is worn or stuck, only the transmission assembly 30 needs to be replaced, without replacing the first structural member 10 and the second structural member 20. This is convenient, fast and cost-effective. At the same time, the first limiting portion 61 and the second limiting portion 62 can be replaced as needed.

[0107] Among them, when the first structural member 10 moves between the intermediate position and the expansion limit position, the first limiting portion 61 can move with the movement of the first transmission member 31. At this time, the first limiting portion 61 limits the movement of the second limiting portion 62 during its own movement. In the above process, the first limiting portion 61 can also be limited by the second structural member 20 and remain stationary relative to the second structural member 20. At this time, the first limiting portion 61 is transmission-connected with the second limiting portion 62. The stationary state of the first limiting portion 61 also makes the second limiting portion 62 stationary, thereby limiting the movement of the second limiting portion 62.

[0108] For example, when the first structural member 10 moves between the intermediate position and the deployment limit position (eg Figure 19 The first stopper 61 is slidably connected to the second stopper 62. Specifically, the first stopper 61 moves with the movement of the first transmission member 31. During this movement, the first stopper 61 slides relative to the second stopper 62, limiting the movement of the second stopper 62 and thus securing the windshield in the open position. Thus, as the first structural member 10 rotates from the closed position through the intermediate position toward the extended limit position, the first stopper 61 can achieve a sliding connection with the second stopper 62 without changing its motion state or connection with the first transmission member 31. This smooth transition prevents shock and vibration caused by sudden braking and reduces wear between the first stopper 61 and the second stopper 62. Furthermore, the sliding connection between the first stopper 61 and the second stopper 62 precisely prevents the second stopper 62 from stopping, thereby accurately positioning the second transmission member 32. This stopper structure 60 has a simple composition and coordination, does not require a complex electronic control system, is less susceptible to environmental influences, and offers high reliability and good repeatability.

[0109] When the first structural member 10 rotates between the closed position and the intermediate position (eg Figure 16 ), the first limiting portion 61 and the second limiting portion 62 may be spaced apart, when the first structural member 10 is in the middle position (such as Figure 17 ), the first rack 312a and the second rack 322a are at the boundary between engagement and separation, and the first limiting portion 61 and the second limiting portion 62 are also at the boundary between separation and contact. In other embodiments, when the first structural member 10 rotates between the closed position and the intermediate position, the first limiting portion 61 and the second limiting portion 62 may also remain in a state of constant transmission connection, which is not a limitation herein.

[0110] Specifically, the first limiting portion 61 is provided on the first shaft 311, and the first limiting portion 61 and the first rack 312a are arranged along the axial direction of the first shaft 311 (eg, Figure 15), the two can be spaced apart or connected, which is not limited here. The first limiting portion 61 has a limiting surface 611, which can be a curved surface or a flat surface. Among them, the first limiting portion 61 can be a block structure protruding from the circumferential side of the first shaft 311. In this case, the limiting surface 611 can be the outer surface of the first limiting portion 61 on the side away from the first shaft 311. The second limiting portion 62 is provided on the second shaft 321, and the second limiting portion 62 and the second rack 322a are arranged along the axial direction of the second shaft 321. The two can be spaced apart or connected, which is not limited here. The second limiting portion 62 forms a limiting groove 621, wherein the second limiting portion 62 can be a block structure protruding from the circumferential side surface of the second shaft 321, and the second limiting portion 62 has a limiting groove 621 on its surface. The second limiting portion 62 can also be a surface structure, which is surrounded by the limiting groove 621, that is, the surface structure is the groove wall surface of the limiting groove 621. At this time, the limiting groove 621 can be opened on the circumferential side surface of the first shaft 311.

[0111] When the first structural member 10 moves between the intermediate position and the deployment limit position (eg Figures 17 to 20 ), the first limiting portion 61 is at least partially located within the limiting groove 621 to limit the rotation of the second limiting portion 62 in at least one direction. It is understood that when the first structural member 10 moves between the intermediate position and the extended limit position, the first limiting portion 61 may be at least partially located in the movement path of the positive groove sidewall of the first limiting portion 61 when it rotates in the reverse direction. Therefore, the first limiting portion 61 can at least limit the reverse rotation of the second limiting portion 62, thereby limiting the baffle 40 in the open position. The first limiting portion 61 limiting the rotation of the second limiting portion 62 refers to limiting the reverse rotation of the second limiting portion 62, or limiting both positive and reverse rotation of the second limiting portion 62. In this way, the first limiting portion 61 can accurately limit the position of the second limiting portion 62 by sliding within the limiting groove 621, thereby achieving accurate positioning of the second limiting portion 62. This has a simple structure and is easy to assemble. After assembly, when the second limiting portion 62 needs to be limited, it is only necessary for the first limiting portion 61 to be at least partially located within the limiting groove 621, thereby reducing the requirements for installation accuracy. In other embodiments, the first limiting portion 61 may not be convexly provided on the circumferential side surface of the first shaft 311, but may be flush with or recessed in the circumferential side surface of the first shaft 311. The second limiting portion 62 may also not be convexly provided on the circumferential side surface of the second shaft 321, but may be flush with or recessed in the circumferential side surface of the second shaft 321. This is not a limitation herein.

[0112] Optionally, the cross-section of the groove wall of the limiting groove 621 is arc-shaped, and the cross-section of the limiting surface 611 is also arc-shaped, so that the limiting surface 611 can adapt and fit with the groove wall of the limiting groove 621. In other words, when the first structural member 10 is between the intermediate position and the extended limit position, the limiting surface 611 slides along the groove wall of the limiting groove 621. In this way, no matter how the first limiting portion 61 moves, the second limiting portion 62 can remain in place, thus achieving dual restrictions on the forward and reverse rotation of the second limiting portion 62, thereby achieving accurate positioning of the baffle 40. The above-mentioned cross-sections all refer to cross-sections perpendicular to the rotation axis of the first shaft 311.

[0113] Figure 21 and Figure 22 They are partial cross-sectional views of the electronic device in different embodiments of the present application, wherein: Figure 21 and Figure 22 The third limiter is set in a different way. Figure 21 and Figure 22 As shown, optionally, the limiting surface 611 is in sliding connection with only a portion of the groove wall surface facing the positive direction of the limiting groove 621, and the limiting surface 611 is separated from the groove wall surface facing the negative direction of the limiting groove 621. In this way, when the first structural member 10 is between the intermediate position and the extended limit position, the first limiting portion 61 can limit the reverse rotation of the second limiting portion 62. It should be noted that the contact portion on the groove wall surface of the limiting groove 621 that is in sliding connection with the limiting surface 611 can be point contact, line contact, or surface contact, and this is not limited here.

[0114] In this case, the baffle 40 can be maintained in the open position under the action of gravity. Alternatively, the limiting structure 60 can be configured to further include a third limiting portion 63 provided on the second structural member 20. The third limiting portion 63 is used to limit the baffle 40 in the open position. The provision of the third limiting portion 63 can compensate for the insufficient limiting effect of the first limiting portion 61 on the second limiting portion 62, thereby improving the reliability of the limiting effect on the baffle 40. There are various ways to configure the third limiting portion 63, which are described below by way of example.

[0115] like Figure 21 As shown, for example, when the baffle 40 is in the open position, it abuts against the third stopper 63. The third stopper 63 can be the wall of the air outlet 202 or another abutting structure provided on the second structural member 20. In this way, the third stopper 63 can limit the movement of the baffle 40 away from the shielding position, thereby reducing the machining accuracy of the stopper slot 621 and lowering the machining cost.

[0116] like Figure 22As shown, for example, when the baffle 40 is in the open position, the second transmission member 32 abuts against the third limiter 63. Thus, the third limiter 63 can restrict the second shaft 321 from continuing to rotate in the forward direction. This arrangement avoids acting on the baffle 40, reducing wear on the baffle 40.

[0117] The abutment between the second transmission member 32 and the third limiting portion 63 may also be an interference fit. For example, the third limiting portion 63 includes an elastic structure provided on the second structural member 20. When the baffle 40 is in the open position, the second transmission member 32 can be elastically engaged with the elastic structure. When the first structural member 10 rotates past the intermediate position and moves toward the closed position, the first rack 312a and the second rack 322a re-engage, and the second transmission member 32 can release the elastic engagement with the elastic structure under the force applied by the first transmission member 31, thereby achieving reverse rotation. This elastic structure is simple, easy to set up, and low in cost. It also facilitates the user to manually reset the baffle 40 to the shielding position. In this way, when the electronic device is turned off and the first structural member 10 has not rotated to the closed position, the baffle 40 can also return to the shielding position to prevent external dust from entering. The shape of the elastic structure includes but is not limited to a spring, an elastic block, a spring, an elastic bar, etc.

[0118] It should be noted that when the second transmission member 32 is elastically engaged with the elastic structure, the elastic structure may be in the process of being squeezed and deformed, or may have just been squeezed and deformed and has returned to its original state, without limitation herein. The elastic engagement includes an interference fit, i.e., when the baffle 40 is in the open position, the second transmission member 32 and the third limiting portion 63 form an interference fit through relative abutment and movement, at which point the third limiting portion 63 undergoes slight elastic deformation.

[0119] Of course, in other embodiments, the third limiting portion 63 may not undergo elastic deformation, but the second transmission member 32 may undergo elastic deformation. This is not limited here. In addition, when the baffle 40 is in the open position, the baffle 40 may also be elastically connected to the elastic structure. At this time, the elastic structure or the baffle 40 undergoes elastic deformation.

[0120] Figure 23 FIG. 1 is a partial cross-sectional view of another embodiment of the electronic device of the present application. Figure 23As shown, as another implementation method, the first limiting portion 61 may also be provided on the first structural member 10 instead of on the first transmission member. When the first structural member 10 rotates, it drives the first limiting portion 61 to rotate synchronously. The first limiting portion 61 may be provided on a side edge of the first structural member 10 close to the rotating assembly. The second limiting portion 62 is provided on the second transmission member 32. The first limiting portion 61 can limit the movement of the second limiting portion 62. The structure and function of the first limiting portion 61 may be the same as the structure and function of the first limiting portion 61 installed on the first transmission member 31 in the above implementation method. The structure and function of the second limiting portion 62 are also the same as those in the above implementation method, and are not described here.

[0121] Figure 24 FIG. 1 is a partial cross-sectional view of another embodiment of the electronic device of the present application. Figure 24 As shown, as another implementation, the limiting structure 60 includes a damping member 64, which is disposed between the second transmission member 32 and the second structural member 20. It is understood that the damping member 64 can be disposed on the second transmission member 32 and abutted against the second structural member 20, in which case a damping force is generated between the damping member 64 and the second structural member 20. The damping member 64 can also be disposed on the second structural member 20 and abutted against the second transmission member 32, in which case a damping force is generated between the damping member 64 and the second transmission member 32. When the first structural member 10 is between the intermediate position and the extended limit position, the baffle 40 remains stationary under the action of the damping force. For example, if the damping member 64 is disposed on the second transmission member 32, when the user drives the first structural member 10 to rotate between the closed position and the intermediate position, the damping member 64 can overcome the damping force between the damping member 64 and the second structural member 20 and rotate with the rotation of the second transmission member 32. When the first structural member 10 rotates past the intermediate position and enters a position between the intermediate position and the extended limit position, the first transmission member 31 and the second transmission member 32 are disconnected from each other, and the second transmission member 32 becomes stationary under the action of the damping force, thereby maintaining the baffle 40 in its current open position. This arrangement reduces the number of components in the position-limiting structure 60 and reduces the requirements for installation precision. Accordingly, the second structural member 20 can also be provided with a damping structure 323 that cooperates with the damping member 64 to increase the damping force between the two.

[0122] Optionally, the damping member 64 can be configured so that the damping force first increases and then decreases when the first structural member 10 moves from the closed position toward the middle position. In this way, when the user opens the first structural member 10, the user needs to first increase the force to improve the operating feel and avoid the first structural member 10 from being opened by mistake, and then reduce the force so that the user can easily adjust the angle of the first structural member 10 when in use, while avoiding too obvious changes in damping when turning past the middle position.

[0123] The damping member 64 may be a first torsion structure 64 a , which can provide torsion for the rotation of the second transmission member 32 . Figure 25 This is a partial assembly structure diagram of the transmission component in one embodiment of the electronic device of this application. Figure 25 As shown, specifically, the first torsion structure 64a includes a shaft rod 641, a disc spring group 642 and a concave-convex group 643 arranged at one end of the disc spring group 642, the disc spring group 642 includes a plurality of stacked disc springs, the concave-convex group 643 includes a first tooth block 6431 and a second tooth block 6432, the first tooth block 6431 has a corrugated first arc surface, the second tooth block 6432 has a corrugated second arc surface, the first tooth block 6431 and the second tooth block 6432 are both connected to the shaft rod 641, wherein the first tooth block 6431 is slidably connected to the shaft rod 641 along the axial direction of the shaft rod 641, the second tooth block 6432 is rotatably connected to the shaft rod 641, the first tooth block 6431 is connected to the disc spring group 642, the first arc surface and the second arc surface face each other and abut against each other under the elastic force of the disc spring group 642. One of the disc spring assembly 642 and the second tooth block 6432 is connected to the second structural member 20, and the other is connected to the second transmission member 32. When the first structural member 10 is in the closed position, the first curved surface and the second curved surface are aligned with each other, that is, the peaks of the first curved surface correspond to the troughs of the second curved surface, and the troughs of the first curved surface correspond to the peaks of the second curved surface. When the first transmission member 31 drives the second transmission member 32 to rotate, the wave crest of the first arcuate surface moves toward the wave crest of the second arcuate surface, the first tooth block 6431 squeezes the disc spring assembly 642, and the disc spring assembly 642 is compressed and deformed, increasing the elastic force applied to the first tooth block 6431. Consequently, the abutment force of the first tooth block 6431 on the second tooth block 6432 also increases. As the first structural member 10 rotates toward the intermediate position, the damping force increases. The second tooth block 6432 continues to rotate, the wave crest of the first arcuate surface passes over the wave crest of the second arcuate surface, and moves toward the next trough. The disc spring assembly 642 stretches, releasing the elastic force, and the abutment force of the first tooth block 6431 on the second tooth block 6431 decreases, thereby reducing the damping force on the first structural member 10. In this way, the damping force on the first structural member 10 first increases and then decreases. It should be noted that the first torsion structure 64a does not need to be set between the first structural member 10 and the second structural member 20. Instead, the change of torque can be achieved through the damping member 64. Another identical or different first torsion structure 64a can also be set. This is not limited here.

[0124] Figure 26 FIG. 1 is a partial cross-sectional view of another embodiment of the electronic device of the present application. Figure 26As shown, as another implementation method, the limiting structure 60 also includes an elastic portion 65, and the first limiting portion 61 can be elastically connected to the first transmission member 31 through the elastic portion 65. When the first structural member 10 moves between the closed position and the intermediate position, the first limiting portion 61 and the second limiting portion 62 do not interact, that is, the first limiting portion 61 and the second limiting portion 62 are spaced apart. The above-mentioned third limiting portion 63 is provided on the second structural member 20, and the third limiting portion 63 is used to limit the forward rotation of the second transmission member 32 when the first structural member 10 is in the intermediate position. The first limiting portion 61 has a first abutting surface and a second abutting surface. When the first structural member 10 reaches the intermediate position, the first limiting portion 61 abuts against the second limiting portion 62 in the opposite direction of the second limiting portion 62 through the first abutting surface, and the first limiting portion 61 abuts on the second structural member 20 through the second abutting surface. The second structural member 20 can limit the movement of the second abutting surface of the first limiting portion 61. Accordingly, the second abutting surface of the first limiting portion 61 is also limited in movement, thereby preventing the second limiting portion 62 from rotating in the opposite direction. The second transmission member 32 is limited in its current position, so that the baffle 40 remains in the open position. When the first structural member 10 continues to move toward the extended limit position, the elastic portion 65 elastically deforms, but the positions of the first and second abutting surfaces of the first limiting portion 61 remain unchanged. When the first structural member 10 rotates from the extended limit position toward the intermediate position, the elastic member returns to its original state under the action of its own elastic restoring force. When the first structural member 10 rotates past the intermediate position and enters a position between the closed position and the intermediate position, the first abutting surface of the first limiting portion 61 separates from the second limiting portion 62, and the second abutting surface of the first limiting portion 61 separates from the second structural member 20. In this way, the first limiting portion 61 not only limits the second limiting portion 62, but also when the user moves the first structural member 10 from the middle position toward the expansion limit position, the deformation of the elastic portion 65 gradually increases, and the force to be applied by the user also gradually increases, thereby increasing the operating feel and preventing the user from applying too much force when the first structural member 10 is close to the expansion limit position without knowing it, resulting in excessive force on the first structural member 10 when it reaches the expansion limit position, causing damage to the first structural member 10.
