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 usually have high heat dissipation requirements. For example, a laptop computer has a fan or other blowing structure installed in the keyboard side housing, and air is discharged through the openings on the side of the keyboard side housing. However, if the appearance of the electronic device is considered, the size of the opening needs to be reduced, but the air discharge effect of a small opening is poor and cannot meet the heat dissipation requirements; if the opening size is increased considering the air discharge effect and heat dissipation requirements of the electronic device, the internal components of the electronic device may be exposed, reducing the appearance of the electronic device. Summary of the invention

[0003] The embodiment of the present application provides an electronic device, which solves the problem that current electronic devices cannot achieve both better air outlet effects and higher aesthetics.

[0004] To achieve the above-mentioned purpose, an embodiment of the present application provides an electronic device, including 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 can move between a closed position and an extended limit position relative to the second structural member. The first structural member also has an intermediate position between the closed position and the extended limit position, and the baffle is movably connected to the second structural member. The above-mentioned movable connection method includes but is not limited to a rotation connection, a sliding connection, etc. The baffle is at least connected to the first structural member through a transmission assembly when the first structural member is between the closed position and the intermediate position. The first structural member can drive the baffle to move from the shielding position to the open position when it moves from the closed position to the intermediate position. When the baffle needs to move from the open position to the shielding position, it can be achieved by moving the first structural member from the intermediate position to the closed position, or by manually moving the baffle. A hollow portion is provided on the second structural member, and the shielding area of ​​the hollow portion by the baffle when it is in the open position is greater than the shielding area of ​​the hollow portion by the baffle when it is in the shielding position. At least a limiting structure is provided on the transmission component, 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 middle position and the expansion limit position.

[0005] When the electronic device is in a non - use state, the first structural member is in the closed position, and the baffle is in the shielding position, thereby improving the aesthetics of the electronic device in the non - use state. When the electronic device is in a use state, the baffle can reach the open position when the first structural member is at an intermediate position between the closed position and the deployment limit position, and as the opening degree of the first structural member increases, the opening degree of the baffle no longer continues to increase under the restriction of the limiting structure. In this way, during normal use by the user, the position of the baffle can meet both the air volume requirement of the hollow part and block the hollow part within a certain viewing angle, thus taking into account both the heat dissipation effect and the aesthetics of the electronic device in the use state.

[0006] As some possible implementation manners, the transmission assembly includes a first transmission member and a second transmission member. The first transmission member is connected to the first structural member, the second transmission member is connected to the second structural member, and the baffle is drivingly 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 drivingly connected to the second transmission member. When the first structural member moves between the intermediate position and the deployment limit position, the first transmission member is disengaged from the driving connection with the second transmission member. In this way, when the first structural member is between the intermediate position and the deployment limit position, the second transmission member no longer receives the acting force exerted by the first transmission member, and the limiting structure only needs to maintain the current open position of the baffle, reducing the wear on the second transmission member.

[0007] As some possible implementation manners, the limiting structure at least includes a first limiting portion and a second limiting portion. The first limiting portion is disposed on the first transmission member or the first structural member, and the second limiting portion is disposed on the second transmission member. When the first structural member is between the intermediate position and the deployment limit position, the first limiting portion can restrict the movement of the second limiting portion. In this way, the limiting structure can limit the second transmission member through the restriction of the first limiting portion on the second limiting portion, thereby realizing the limitation of the baffle. By respectively disposing the first limiting portion and the second limiting portion on the first transmission member and the second transmission member, it is convenient for detection, maintenance, and replacement, simplifying the installation process. When the limiting structure is worn or jammed, only the transmission assembly needs to be replaced, without replacing the first structural member and the second structural member, which is convenient, fast, and cost - saving. At the same time, appropriate first limiting portion and second limiting portion can be replaced according to actual needs.

[0008] As some possible implementation manners, when the first structural member moves between the middle position and the deployment 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 middle position towards the deployment limit position, the first limiting portion can achieve the slidable connection with the second limiting portion without changing the motion state and the connection state with the first transmission member, with a smooth transition, avoiding the impact and vibration that may be generated by sudden braking, and at the same time 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 to stop moving by slidably connecting with the second limiting portion, so as to achieve the accurate positioning of the second transmission member. The composition and cooperation mode of this limiting structure are simple, without relying on a complex electronic control system, less affected by the environment, with high reliability and good repeatability.

[0009] As some possible implementation manners, 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. The first limiting portion is disposed on the first shaft or the first structural member. 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. The second limiting portion is disposed on the second shaft. The second limiting portion forms a limiting groove. When the first structural member moves between the closed position and the middle position, the first transmission structure is in transmission connection with the second transmission structure. When the first structural member moves between the middle position and the deployment limit position, the first transmission structure is disengaged from the transmission connection with the second transmission structure, and at least a part of the first limiting portion is located in 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 can rotate forward and backward. The first limiting portion can limit the forward rotation of the second limiting portion, or limit the backward rotation of the second limiting portion, or limit both the forward rotation and the backward rotation. Among them, the rotation direction of the second limiting portion when the first structural member moves from the closed position towards the middle position can be defined as the forward rotation. In this way, the position of the second limiting portion is accurately limited by the sliding of the first limiting portion in the limiting groove, achieving the accurate positioning of the second limiting portion. The structure is simple and convenient to assemble. After assembly, only when the second limiting portion needs to be limited, at least a part of the first limiting portion needs to be located in the limiting groove, reducing the requirement for the installation accuracy.

[0010] As some possible implementation manners, the first transmission structure includes a first rack disposed on the first shaft, the first rack extending along the circumferential direction of the first shaft, and the second transmission structure includes a second rack disposed on the second shaft, the second rack extending along the circumferential direction of the second shaft. When the first structural member moves between the closed position and the intermediate position, the first rack meshes with the second rack, so that the second transmission member drives the baffle to move between the shielding position and the open position; when the first structural member moves between the intermediate position and the shielding position, the first rack and the second rack are separated. The arrangement of the first rack and the second rack is convenient for assembly and has high reliability.

[0011] As some possible implementation manners, the central angle corresponding to at least one of the first rack and the second rack is 60°-120°. When a user normally uses the device, the first structural member is generally rotated by 90°-120°, and at this time, the baffle may already be in the open position, so that the heat dissipation effect of the electronic device is optimal, or the baffle is close to the open position, so that the heat dissipation effect of the electronic device is close to optimal.

[0012] As some possible implementation manners, the first limiting portion has a limiting surface, and the cross section of the wall surface of the limiting groove is arc-shaped. When the first structural member moves between the intermediate position and the expanded limit position, the limiting surface can be adapted to and fit with the wall surface of the limiting groove and slide relative to the wall surface of the limiting groove. In this way, no matter how the first limiting portion moves, the second limiting portion can remain in place, that is, the double limitation of the forward rotation and the reverse rotation of the second limiting portion is realized, thereby realizing the accurate positioning of the baffle.

[0013] As some possible implementation manners, the first limiting portion has a limiting surface. When the first structural member moves from the closed position towards the expanded limit position, the second limiting portion rotates in the forward direction, and the first limiting portion is slidably connected to the upward wall surface of the limiting groove in the positive direction through the limiting surface. In this way, when the first structural member is between the intermediate position and the expanded limit position, the first limiting portion can limit the reverse rotation of the second limiting portion.

[0014] As some possible implementation manners, the limiting structure further includes a third limiting portion disposed on the second structural member, and the third limiting portion is used to limit the baffle to the open position. The third limiting portion can be used to limit the forward rotation of the second limiting portion, so that the double limitation of the second transmission member is jointly realized by combining the limitation of the reverse rotation of the second limiting portion by the first limiting portion. The third limiting portion can also independently realize the double limitation of the second limiting portion. That is to say, the arrangement of the third limiting portion can make up for the deficiency of the first limiting portion in limiting the second limiting portion and improve the reliability of limiting the baffle.

[0015] As some possible implementation manners, the third limiting portion 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 is elastically clamped to the elastic structure. This elastic structure is simple, convenient to set, and low in cost. At the same time, it is convenient for the user to manually control the baffle to reset to the shielding position. In this way, when the electronic device is turned off and the first structural member is not rotated to the closed position, the baffle can also return to the shielding position to prevent external dust from entering.

[0016] As some possible implementation manners, the limiting structure further includes an elastic portion. The first limiting portion is elastically connected to the first transmission member through the elastic portion; when the first structural member moves from the closed position toward the unfolding limit position, the second limiting portion rotates in the positive direction; when the first structural member is in the middle 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 realizes the limitation of the second limiting portion, but also when the user moves the first structural member from the middle position toward the unfolding limit position, due to the gradual increase in the deformation of the elastic portion, the acting force applied by the user also gradually increases, thereby increasing the operation feel and avoiding the first structural member being overstressed when reaching the unfolding limit position due to excessive and unconscious force application by the user when the first structural member is close to the unfolding limit position, causing damage to the first structural member.

[0017] As some possible implementation manners, the limiting structure includes a damping member. The damping member is 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 middle position and the unfolding limit position, the baffle is stationary under the action of the damping force. This setting can reduce the components of the limiting structure and lower the requirement for setting accuracy.

[0018] As some possible implementation manners, during the process of the first structural member moving from the closed position toward the middle position, the damping force generated by the damping member first increases and then decreases. In this way, when the user opens the first structural member, it is necessary to first increase the applied force to improve the operation feel and avoid accidental opening of the first structural member, and then reduce the applied force to facilitate the user to easily adjust the angle of the first structural member in the use state, and at the same time avoid the damping change being too obvious when passing through the middle position.

[0019] As some possible implementation manners, the transmission assembly further includes a mounting member. The mounting member is connected to the second structural member and is provided with 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 first structural member can be rotationally connected to the second structural member through this transmission assembly without separately setting a rotating component, reducing the number of structural members, facilitating assembly, and saving installation space.

[0020] As some possible implementation manners, the transmission assembly further includes a connecting member and a torsion structure. The connecting member includes a connecting portion and a plate portion. The connecting portion is connected to the first shaft and extends along the extending direction of the first shaft. The plate portion is connected to the connecting portion and is in a plate shape. 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 the damping through the torsion structure, improve the operating feel of the first structural member, and avoid accidental opening of the first structural member.

[0021] As some possible implementation manners, the second structural member includes a top plate, a bottom plate and a side plate. The top plate and the bottom plate are oppositely arranged and spaced apart. The side plate is circumferentially connected to the periphery of the top plate and the periphery of the bottom plate and jointly encloses an installation cavity with the top plate and the bottom plate. The hollow portion includes at least one air outlet hole opened on the side plate. The baffle covers the air outlet hole when in the shielding position. In this way, when the electronic device is in a non-use state, the baffle can prevent external dust and water vapor from entering the installation cavity.

[0022] As some possible implementation manners, the baffle has a rotating portion and a shielding portion connected to each other. The rotating portion is rotatably connected to the second structural member. The shielding portion is used to shield the hollow portion when the baffle is in the upper shielding position. The rotation angle of the baffle from the shielding position to the open position is less than or equal to 90°. When the included 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 surface of the third side portion) is within a range greater than 90°, the opening degree of the baffle has basically no influence on the air outlet of the hollow portion, and the air outlet volume of the hollow portion is basically the same as that when the included angle between the shielding surface of the baffle and the plane where the solid portion forming the hollow portion is 90°. At the same time, when the shielding portion of the baffle rotates upward, an included angle greater than 90° easily causes the baffle to affect the rotation of the first structural member towards the unfolded limit position.

[0023] As some possible implementation manners, the transmission assembly further includes a rod chain. The rod chain includes at least a first rod and a second rod. One end of the first rod is fixedly connected to the second transmission member. Two ends of the second rod are respectively rotatably connected to the other end of the first rod and the shielding portion. In this way, the second transmission member is connected to the shielding portion through the first rod and the second rod in sequence. 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 portion to rotate relative to the rotating portion, thereby realizing the rotation of the baffle. This multi-rod structure can bypass some obstacles and has a certain flexibility, and can adapt to different spatial layouts and movement requirements to a certain extent. In addition, when the baffle is suddenly stressed, this multi-rod structure can absorb a 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 device. This connection method can realize the transmission and amplification of force by reasonably designing parameters such as the length and angle of the rod.

[0024] As some possible implementation manners, an arc-shaped sliding groove is provided on the second structural member, and the rotating portion is slidably connected to the arc-shaped sliding groove, and the rotation axis of the rotating portion coincides with the central axis corresponding to the sliding groove. In this way, the space occupied by the baffle during rotation is reduced, avoiding affecting the installation of other devices in the installation cavity. At the same time, when the baffle is in the open position, the baffle can still be located within the air outlet hole or protrude less from the air outlet hole, thereby improving the aesthetics of the electronic device, while reducing the bumps received by the baffle and improving the reliability of the baffle.

[0025] As some possible implementation manners, the first structural member has an installation cavity, and the hollow portion communicates with the installation cavity. When the baffle moves from the shielding position towards the open position, the shielding portion moves in a direction 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 implementation manners, when the baffle is in the shielding position, the rotating portion is located on the side of the shielding portion close to the first structural member. In this way, when the user flips the first structural member for use, the shielding portion rotates upward. In the usage state of the electronic device, the baffle is located above the hollow portion, and the hollow portion blows air horizontally or blows air obliquely downward under the guiding action of the shielding surface. The user's height is higher than that of the second structural member. Therefore, the baffle can block the user's line of sight towards the hollow portion, thereby improving the aesthetics of the appearance of the electronic device.

[0027] As some possible implementation manners, 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 laptop computer, and the laptop computer can take into account both the aesthetics of the appearance and the heat dissipation effect by setting the transmission assembly and the baffle.

[0032] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments.

[0033] Figure 1 This is a three-dimensional structure diagram of the electronic device provided by the embodiment of the present application. Figure 2 is Figure 1 the cross-sectional view of the electronic device in Figure 1 at A-A. As Figure 2As shown in the figure, an embodiment of the present application provides an electronic device, which includes a first structural member 10 and a second structural member 20 that are movably connected. The movable connection methods include but are not limited to rotational connection and sliding connection. In this electronic device, at least the housing of the second structural member 20 forms an installation cavity 201, and a control device 91 is arranged in the installation cavity 201. The control device 91 is used to control the electronic device to implement certain functions. The control device 91 includes but is not limited to chips, circuit boards, and electronic components. Among them, the chips include but are not limited to system-on-chip (SoC), central processing unit (CPU), graphics processing unit (GPU), universal flash storage (UFS) chips, basic input / output system chips (BIOS), intelligent algorithm chips, etc. The circuit boards include but are not limited to rigid circuit boards, flexible printed circuit (FPC) boards, etc. The electronic components include but are not limited to resistors, capacitors, inductors, potentiometers, electron tubes, heat sinks, electromechanical components, connectors, semiconductor discrete devices, laser devices, optoelectronic devices, sensors, switches, micro motors, electronic transformers, relays, speakers, microphones, cameras, antennas, etc. Each electronic component can be independently arranged and communicatively connected to the circuit board or the chip, or can be combined with the circuit board and / or the chip to form a functional module. The specific arrangement method can be determined according to the usage requirements.

[0034] Among them, heat will be generated during the use of the control device 91, and the accumulation of this heat in the installation cavity 201 will affect the performance of the control device 91. Therefore, it is necessary to open an air outlet hole 202 on the housing of the electronic device that communicates with the installation cavity 201. In this way, the heat in the installation cavity 201 can be discharged through the air outlet hole 202.

[0035] Figure 3 It is a three-dimensional structure diagram of a current related electronic device. As Figure 3 shown, the size of the air outlet hole 202 on the housing of the electronic device (such as the second structural member 20) directly affects the aesthetics and air outlet effect of the electronic device. If the size of the air outlet hole 202 is relatively large, although it can meet the air outlet effect and heat dissipation requirements of the electronic device, it may cause the internal components of the electronic device to be exposed, reducing the aesthetics of the electronic device. If the size of the air outlet hole 202 is relatively small, although it can improve the aesthetics of the appearance of the electronic device, it will cause a poor air outlet effect of the electronic device and cannot meet the heat dissipation requirements of the electronic device. Therefore, the current related electronic devices cannot balance a better air outlet effect and a higher aesthetics.

[0036] To solve the above problems, an embodiment of the present application provides an electronic device. The electronic device can dissipate heat through the air outlet hole 202 in the use state to meet the heat dissipation requirements of the electronic device, and can shield at least part of the air outlet hole 202 in the non-use state to improve the aesthetics. The electronic device can be a laptop computer, a convertible tablet computer, an ultra-mobile personal computer (UMPC), a netbook, a vehicle-mounted device, etc.

[0037] For ease of description, in the following embodiments, the electronic device is taken as a laptop computer as an example for description. Figure 4 This is a three-dimensional structure diagram of the electronic device in the use state in some embodiments of the present application. As Figure 4 shown, wherein, the first structural member 10 is rotatably connected to the second structural member 20, and the rotational connection method includes but is not limited to hinge connection, bearing connection, spline connection, coupling connection, etc. Among them, the first structural member 10 rotates around its rotation axis, and the rotation axis of the first structural member 10 can be the rotation axis of a physical axis or a virtual axis, which is not limited here. The virtual axis refers to the rotation axis of an axis that does not exist as an actual physical entity simulated through design or technology.

[0038] For a laptop computer, the first structural member 10 can be selected to include a display-side housing 10a, and a display screen 93 can be arranged on the display-side housing 10a. The second structural member 20 can be selected to include a keyboard 94-side housing 20a, and a keyboard 94 can be arranged on the keyboard 94-side housing 20a.

[0039] Among them, both the first structural member 10 and the second structural member 20 are plate-shaped. The first structural member 10 has an opposite display surface 10a1 and a top surface 10a2. The display screen 93 is arranged on one side of the display surface 10a1 of the first structural member 10. The second structural member 20 has an opposite mounting surface 20a1 and a bottom surface 20a2. The keyboard 94 is arranged on one side of the mounting surface 20a1 of the second structural member 20. Both the first structural member 10 and the second structural member 20 have opposite first ends and second ends, and 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 can also be rotatably connected to the middle of the second structural member 20, which is not limited here.

[0040] Figure 5 This is a three-dimensional view of the electronic device in an embodiment of the present application, wherein the first structural member is in the closed position; Figure 6 For Figure 5 a cross-sectional view of the electronic device at B-B in. Among them, the keyboard 94-side housing 20a forms a mounting cavity 201 and an air outlet hole 202 communicating with the mounting cavity 201. A control device 91 is arranged in the mounting cavity 201, and the keyboard 94 (combinedFigure 4 ), and the display screen 93 are both communicatively 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 according to the instructions (in combination with Figure 4 ) to display an image or control the functional devices therein to execute relevant instructions. To improve the heat dissipation efficiency, a fan 92 can be provided in the installation cavity 201, and an air inlet hole 203 communicating with the installation cavity 201 is also provided on the outer shell. Under the action of the fan 92, air can enter the installation cavity 201 from the air inlet hole 203, and exchange heat with heat-generating devices such as the control device 91 to form a hot air flow. The hot air flow is discharged from the air outlet hole 202 out of the installation cavity 201, thereby realizing the heat dissipation of the electronic device.

[0041] When the electronic device is in use, the second structural member 20 is placed on the desktop, and at this time, the bottom surface 20a2 of the second structural member 20 abuts against the desktop. Among them, the installation surface 20a1 of the second structural member 20 faces upward, the bottom surface 20a2 faces downward, the up and down directions are the thickness direction of the second structural member 20, the first end of the second structural member 20 is located at the rear side of the second structural member 20, the second end of the second structural member 20 is located at the front side of the second structural member 20, and the extending directions of the two extending ends of the rotation axis of the first structural member 10 are the left side and the right side respectively. It should be noted that the spatial orientation of the electronic device described in the following embodiments is the same as that of the second structural member 20.

[0042] Figure 7 This is a three-dimensional structure diagram of the electronic device in some embodiments of the present application, in which the first structural member is in the expanded limit position. As Figure 5 and Figure 7As shown, the first structural member 10 can rotate between a closed position and an extended limit position. Specifically, when the electronic device is in a non-use state, the first structural member 10 is in the closed position, and the closed position can be selected as the position where the first structural member 10 is engaged with the second structural member 20. At this time, the display screen 93 on the first structural member 10 faces the keyboard 94 on the second structural member 20, and the display surface 10a1 of the first structural member 10 can be selected to abut against the mounting surface 20a1 of the second structural member 20, and the display surface 10a1 is parallel to the mounting surface 20a1, that is, the included angle between the display surface 10a1 and the mounting surface 20a1 is 0°. When the electronic device needs to be used, the front end of the first structural member 10 can be rotated upward and then flipped backward until the first structural member 10 cannot be rotated or does not need to be rotated, and the extended limit position of the first structural member 10 is reached. The angle by which the first structural member 10 rotates from the closed position to the extended limit position can be selected to be greater than or equal to 120° and less than or equal to 360°. When the user has finished using it, the first structural member 10 can be rotated in the reverse direction to the closed position. That is to say, the first structural member 10 can move relative to the second structural member 20 between the closed position and the extended limit position. When the user is viewing the display screen 93, the first structural member 10 can be located at the extended limit position or between the closed position and the extended limit position. Among them, the included 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 degree of the first structural member 10. The larger the included angle between the two, the larger the opening degree of the first structural member 10, and the smaller the included angle between the two, the smaller the opening degree of the first structural member 10.

[0043] Generally, for a notebook computer, when the first structural member 10 is at the extended limit angle, the included 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°. Among them, when the user is viewing the display screen 93, the included 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° (as Figure 4 shown). In other embodiments, when the first structural member 10 is in the closed position, the included angle between the display surface 10a1 of the first structural member 10 and the mounting surface 20a1 of the second structural member 20 can also be a specific angle greater than 0°, which is not limited here.

[0044] As Figure 6 and Figure 7As shown, a hollowed-out portion 21 is provided on the second structural member 20. The second structural member 20 realizes the air outlet of the installation cavity 201 through the hollowed-out portion 21, so as to realize the heat dissipation of the control device 91 in the installation cavity 201. The hollowed-out portion 21 can be a hole structure, a groove structure, a notch structure, a grille structure, a louver structure, a heat sink structure, a honeycomb structure, etc., as long as it can realize the ventilation of the accommodation cavity. In some embodiments, the hollowed-out portion 21 includes but is not limited to at least one air outlet hole 202. When the hollowed-out portion 21 has a plurality of air outlet holes 202, the plurality of air outlet holes 202 can be arranged in an array or irregularly, and no limitation is made here. The plurality of air outlet holes 202 can make the solid part forming the hollowed-out portion 21 form a grid-like structure, a pattern structure, an array structure, etc. The cross-sectional shape of the air outlet hole 202 includes but is not limited to a square, a circle, a semicircle, a sector, an ellipse, a regular polygon, a special shape, etc., and no limitation is made here. Among them, the cross-section of the air outlet hole 202 refers to the cross-section perpendicular to the opening direction of the air outlet hole 202. The air flow in the installation cavity 201 can flow out of the air outlet hole 202 along the opening direction of the air outlet hole 202, that is, the opening direction of the air outlet hole 202 is the air outlet direction of the air outlet hole 202. The solid parts forming the hollowed-out portion 21 can be located on the same plane or not on the same plane, and no limitation is made here.

[0045] Figure 8 is a partial explosion view of the electronic device in the embodiment of the present application, wherein the baffle is in the shielding position. As Figure 8 shown, in the embodiment of this application, the electronic device further includes a transmission assembly 30 and a baffle 40. The electronic device drives the baffle 40 to block or avoid the air outlet hole 202 through the transmission assembly 30.

[0046] Specifically, the baffle 40 is movably connected to the second structural member 20, and the movable connection manners 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 in transmission connection with the transmission assembly 30, and the transmission assembly 30 is in transmission connection with the first structural member 10, that is, the baffle 40 realizes the transmission connection with the first structural member 10 through the transmission assembly 30. Among them, the transmission assembly 30 may not have a connection relationship with the second structural member 20, or may be in transmission connection with the second structural member 20. At this time, the first structural member 10 and the second structural member 20 may realize rotational connection only through the transmission assembly 30, or may realize rotational connection through other structural members independent of the transmission assembly 30, or may also realize rotational connection through the combination of the transmission assembly 30 and other structural members, which is not limited here. The above-mentioned transmission connection manners include but are not limited to mechanical transmission (such as belt transmission, rod transmission, chain transmission, gear transmission, worm transmission, etc.), fluid transmission (hydraulic transmission, pneumatic transmission, etc.), electric drive (such as direct drive of a motor, power electronic drive, etc.) and magnetic drive. When the first structural member 10 is between the intermediate position and the deployment limit position, the baffle 40 may still maintain the transmission connection with the first structural member 10 through the transmission assembly 30, or the baffle 40 may only maintain the transmission connection with the transmission assembly 30, the internal transmission connection of the transmission assembly 30 is disconnected, or the transmission assembly 30 is disconnected from the first structural member 10 or the second structural member 20, or the baffle 40 is disconnected from the transmission assembly 30, but the transmission assembly 30 still maintains the transmission connection with the first structural member 10, which is not limited here. One baffle 40 may be connected to the second structural member 20, or multiple baffles 40 may be connected. When multiple baffles 40 are connected to the second structural member 20, some or all of the multiple baffles 40 may be in transmission connection with the same transmission assembly 30, or multiple transmission assemblies 30 may also be provided, and each baffle 40 is in transmission connection with one or more transmission assemblies 30, which is not limited here.

[0047] The baffle 40 may be made of a hard material, such as engineering plastics, metals, composite materials, etc. The baffle 40 may be in a plate-like structure. Among them, the baffle 40 has an occlusion surface. When the baffle 40 is in the shielding position, the airflow blown out from the hollow portion 21 hits the occlusion surface, and the occlusion surface may be a plane, a curved surface or a folded surface, which is not limited here. In other embodiments, the baffle 40 may also be composed of a hard material and a flexible material. For example, the frame of the baffle 40 is formed by a hard material, and the occlusion surface of the baffle 40 is formed by a flexible material.

[0048] Figure 9 A three-dimensional structure diagram of an electronic device provided in some embodiments of the present application, in which the baffle is in the open position. As Figure 8 and Figure 9As shown, the baffle 40 has an open position and a shielding position, and the baffle 40 can move between the open position and the shielding position. The projection area of ​​the baffle 40 in the air outlet 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 the shielding area of ​​the hollow portion 21 when the baffle 40 is in the shielding position. It can be understood that when the baffle 40 is in the open position, the shielding area of ​​the hollow portion 21 of the baffle 40 is a, and when the baffle 40 is in the shielding position, the shielding area of ​​the hollow portion 21 of the baffle 40 is b, and b is greater than a. In this way, when the baffle 40 is in the shielding position, it can shield all or part of the hollow portion 21 to improve the aesthetics of the electronic device. When the baffle 40 is in the open position, the shielding area of ​​the hollow portion 21 of the baffle 40 is reduced, thereby increasing the air outlet volume and improving the air outlet effect to meet the heat dissipation requirements.

[0049] As Figure 9 In the embodiment shown, the solid part forming the hollow portion 21 is on the same plane, and the air outlet direction of the hollow portion 21 is perpendicular to the plane where the solid part 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 air outlet direction of the hollow portion 21, or it can be at other angles other than 90° with the air outlet direction of the hollow portion 21, which is not limited here. When the baffle 40 is in the open position, the shielding surface of the baffle 40 can be parallel to the air outlet direction of the hollow portion 21, or it can be set at an obtuse angle with the plane where the solid part forming the hollow portion 21 is located, so as to reduce or eliminate the shielding of the airflow blown out of the hollow portion 21 by the baffle 40. The angle between the shielding surface of the baffle 40 and the plane where the solid part forming the hollow part 21 is located can be used to indicate 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 part 21, for example, the shielding surface of the baffle 40 and the plane where the solid part forming the hollow part 21 is located form an angle greater than 0°, or the baffle 40 is buckled with the solid part forming the hollow part 21, that is, the angle between the shielding surface of the baffle 40 and the plane where the solid part forming the hollow part 21 is located is 0°, but the baffle 40 avoids part of the hollow part 21, and there is no limitation here, as long as the opening of the baffle 40 when it is in the open position is greater than the opening of the baffle 40 when it is in the shielding position.

[0050] Since the first structural member 10 is linked to the baffle 40 through 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 towards the deployment limit position, the baffle 40 also moves from the shielding position towards the open position. However, if the baffle 40 is set 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 deployment limit position, then the baffle 40 will only move to the open position when the first structural member 10 is in the deployment limit position. Usually, users will not rotate the first structural member 10 to the deployment limit position, but will rotate the first structural member 10 to a position convenient for viewing or operation, which is generally between the closed position and the deployment limit position. Therefore, if the open position is set to just meet the heat dissipation requirements of the electronic device to prevent the baffle 40 from having too large an opening degree in the open position and affecting the aesthetics of the electronic device, then when the user is using it normally, the baffle 40 cannot reach the open position, but is between the shielding position and the open position, and thus cannot meet the heat dissipation requirements of the electronic device. If the opening degree of the baffle 40 when in the open position is set to be larger in order to enable the baffle 40 to meet the heat dissipation requirements of the electronic device when the user is using it normally, this will cause the hollow part 21 to be exposed at a wider angle when the first structural member 10 rotates to the deployment limit position, and thus the user can see the structural members in the installation cavity 201, affecting the aesthetics of the electronic device.

[0051] Based on this, in the embodiments of the present application, a limiting structure is at least provided on the transmission assembly 30. Figure 10 This is a three-dimensional structural diagram of the electronic device in some embodiments of the present application, where the first structural member is in the middle position. As Figure 10 shown, the first structural member 10 has a middle position, which is between the closed position and the deployment limit position. The first structural member 10 can only reach the deployment limit position after passing through the middle position from the closed position. The first structural member 10 can drive the baffle 40 to move from the shielding position to the open position when moving from the closed position to the middle position. When the first structural member 10 moves between the middle position and the deployment limit position, the limiting structure can limit the baffle 40 in the open position. At this time, the first structural member 10 can be disconnected from the transmission connection with the baffle 40, or can still maintain the transmission connection, but the movement of the baffle 40 following the first structural member 10 is restricted by the limiting structure.

[0052] In this way, when the electronic device is in a non-use state, 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 in the non-use state. When the electronic device is in the use state, the baffle 40 can reach the open position when the first structural member 10 is at an intermediate position between the closed position and the deployment limit position, and as the opening degree of the first structural member 10 increases, the opening degree of the baffle 40 no longer continues to increase under the restriction of the limiting structure. In this way, during normal use by the user, the position of the baffle 40 can meet the air volume requirement of the hollow portion 21 and can also block the hollow portion 21 within a certain viewing angle, thereby taking into account the heat dissipation effect and aesthetics of the electronic device in the use state.

[0053] Wherein, the opening degree of the first structural member 10 when it is at the intermediate position can be greater than or equal to the opening degree of the first structural member 10 when the user normally uses the electronic device, so as to ensure that the baffle 40 is already in the open position when the user normally uses the electronic device, so that the air volume of the hollow portion 21 is in the maximum state that can be reached. Of course, in other embodiments, the opening degree of the first structural member 10 when it is at the intermediate position can also be less than the opening degree of the first structural member 10 during normal use, but when the user normally uses it, the opening degree of the first structural member 10 is already close to the opening degree of the first structural member 10 when it is at the intermediate position.

[0054] It should be noted that when the baffle 40 is located at the open position and needs to return to the shielding position, it can be realized by rotating the first structural member 10 from the intermediate position to the closed position to realize the automatic closing of the baffle 40, or it can also be realized by manually moving the baffle 40 to improve the operation freedom, and no limitation is made here.

[0055] As Figure 10 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 oppositely arranged in the thickness direction of the second structural member 20. The top plate 22 has an installation 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 plate 24 is circumferentially connected to the circumferences of the top plate 22 and the bottom plate 23 and jointly encloses an installation cavity 201 with the top plate 22 and the bottom plate 23. The hollow portion 21 includes at least one air outlet hole 202 opened on the side plate 24, and the baffle 40 covers at least one air outlet hole 202 when in the shielding position.

[0056] Optionally, the side plate 24 includes a first side portion, a second side portion 241, a third side portion 242, and a fourth side portion that are connected end to end in sequence. The first side portion is located on the front side 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, and the plurality of air outlet holes 202 are all arranged on the third side portion 242 and are arranged in sequence in the left-right direction. At this time, the third side portion 242 is the solid part forming the hollow portion 21, and the third side portion 242 has a back surface facing away from the installation cavity 201. There is one baffle 40, and when in the shielding position, the baffle 40 can block all the air outlet holes 202 in the front-rear direction. At this time, 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 received in the air outlet holes 202. At this time, the edge of the baffle 40 can be in clearance fit with the hole wall of the air outlet holes 202, and the baffle 40 and the back surface of the third side portion 242 can abut or be spaced apart.

[0057] In other embodiments, the hollow portion 21 can also be provided on the bottom plate 23 and / or the top plate 22, and air outlet holes 202 can also be opened on other side portions of the baffle 40 except the third side portion 242, and there is no limitation here.

[0058] Figure 11 This is a partial exploded view of the electronic device in some embodiments of the present application. As Figure 11As shown, in some embodiments, the baffle 40 has a connected rotating portion 41 and a shielding portion 42. 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 moves in 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 where the solid part forming the hollow portion 21 is located (such as the back surface of the third side portion 242) is less than or equal to 90°, the larger the opening degree of the baffle 40, the smaller the shielding area of the baffle 40 for the hollow portion 21, and the larger the air outlet volume of the hollow portion 21; the smaller the opening degree of the baffle 40, the larger the shielding area of the baffle 40 for the hollow portion 21, and the smaller the air outlet volume of 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 portion 21 is located (such as the back surface of the third side portion 242) is within a range greater than 90°, the size of the opening degree of the baffle 40 has basically no influence on the air outlet of the hollow portion 21, and the air outlet volume of the hollow portion 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 portion 21 is located is 90°. At the same time, when the shielding portion 42 of the baffle 40 rotates upward, an angle greater than 90° easily causes the baffle 40 to affect the rotation of the first structural member 10 towards the unfolded limit position. Therefore, the angle between the shielding surface 401 of the baffle 40 and the plane where the solid part forming the hollow portion 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 since the larger the opening degree of the baffle 40, the wider the angle from which the user can see the hollow portion 21, and thus the devices in the installation cavity 201 through the hollow portion 21, and the smaller the opening degree of the baffle 40, the smaller the angle from which the user can see the hollow portion 21, and thus the fewer devices in the installation cavity 201 that the user can see. Therefore, in practical applications, the open position of the baffle 40 can be set according to the specific structure and design requirements of the electronic device.

[0059] Optionally, when the baffle 40 is in the shielding position, the shielding portion 42 abuts against the second structural member 20, specifically, it can abut against the back surface of the third side portion 242. At this time, the angle between the baffle 40 and the plane where the solid part forming the hollow portion 21 is located is 0°. The rotation angle of the baffle 40 from the shielding position to the open position is 60° - 90°. In this way, the baffle 40 can effectively adjust the air outlet volume, and make the air outlet volume of the baffle 40 large enough when it is in the open position. At the same time, the hollow portion 21 can be shielded as much as possible to reduce the angle from which the user can see the hollow portion 21.

[0060] Optionally, when the baffle 40 is in the shielding position, the rotating portion 41 is located on the side of the shielding portion 42 close 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 the first structural member 10 for use, the shielding portion 42 rotates upward. When the electronic device is in the use state, the baffle 40 is located above the hollow portion 21, and the hollow portion 21 blows air horizontally or blows air obliquely downward under the guiding action of the shielding surface 401. The user's line of sight is higher than the second structural member 20. Therefore, the baffle 40 can block the user's line of sight looking at the hollow portion 21, thereby improving the aesthetic appearance of the electronic device.

[0061] Optionally, when the baffle 40 moves from the shielding position towards the open position, the shielding portion 42 moves in a direction away from the installation cavity 201, that is, the shielding portion 42 moves outward relative to the rotating portion 41 to prevent the movement of the shielding portion 42 from occupying the cavity space of the installation cavity 201.

[0062] Figure 12 For the Figure 11 partial enlarged view of the electronic device in the present application in another embodiment under the perspective in. As Figure 12 shown, optionally, the baffle 40 further has a stopper portion 43 connected to the edge of the shielding portion 42. The stopper portion 43 can form a stepped structure with the shielding surface 401, and the shielding surface 401 protrudes from the stopper portion 43 in the extending direction of its normal line. When the baffle 40 is in the shielding position, the shielding portion 42 is at least partially received in the air outlet hole 202, and the stopper portion 43 abuts against the back surface of the third side portion 242. In this way, the baffle 40 realizes the limit of the baffle 40 in the shielding position through the stopper portion 43, and at the same time improves the sealing performance of the air outlet hole 202. Among them, the stopper portion 43 can be arranged on the edge of the shielding portion 42 away from the rotating portion 41, or can be arranged on the left and right side edges of the shielding portion 42. There is no limitation here as long as the limit of the shielding portion 42 can be realized. It should be noted that when there are multiple air outlet holes 202 and one baffle 40 is used to block all the air outlet holes 202 or two or more air outlet holes 202, the baffle 40 can have multiple shielding portions 42, each shielding portion 42 corresponds to one air outlet hole 202. Correspondingly, there are also multiple rotating portions 41, and each shielding portion 42 corresponds to each rotating portion 41 one by one. The multiple shielding portions 42 are connected through the stopper portion 43.

[0063] The rotation axis of the rotating portion 41 can be not only the axis of the above-mentioned solid axis, but also a virtual axis. As Figure 12As shown, optionally, an arc-shaped sliding groove 204 is provided on the second structural member 20. The arc-shaped sliding groove 204 can be provided on the hole wall of the air outlet hole 202, can also be provided on the cavity wall of the installation cavity 201, or can also be provided on an independent structure connecting the second structural member 20, and there is no limitation here. The rotating part 41 is slidably connected to the arc-shaped sliding groove 204, and the baffle 40 rotates by sliding along the arc-shaped sliding groove 204 through the rotating part 41. The rotation axis of the rotating part 41 coincides with the central axis corresponding to the arc-shaped sliding groove 204. In this way, the space occupied by the baffle 40 during rotation is reduced, avoiding affecting the installation of other devices in the installation 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 hole 202 or protrude less from the air outlet hole 202, thereby improving the aesthetics of the electronic device and reducing the bumps received by the baffle 40, improving the reliability of the baffle 40. In other embodiments, a sliding groove extending along a straight line can also be provided on the hole wall of the air outlet hole 202, and the extending direction of the sliding groove is the same as the opening direction of the air outlet hole 202. When the rotating part 41 rotates, it can also slide along the sliding groove towards the installation cavity 201, and there is no limitation here.

[0064] As Figure 11 and Figure 12 shown, optionally, the baffle 40 may further have a reinforcing part 44. The reinforcing part 44 is in the shape of a rib, and the reinforcing part 44 can be convexly provided on the shielding surface 401 of the shielding part 42 to improve the structural strength of the shielding part 42, avoiding deformation of the baffle 40 when the force is uneven, and at the same time, being provided inside the shielding part 42 can avoid affecting the aesthetics of the appearance of the baffle 40. When the baffle 40 has a plurality of shielding parts 42, the reinforcing part 44 can also be provided on the stopping part 43 between two adjacent shielding parts 42 to improve the reliability of the stopping part 43 and avoid deformation of the baffle 40 at the stopping part 43. Among them, the reinforcing part 44 can be provided on the outer side of the stopping part 43, that is, on the side facing away from the shielding surface 401, to avoid affecting the abutment of the stopping part 43 against the back surface of the third side part 242.

[0065] Optionally, the reinforcing part 44 is provided on the shielding part 42 and extends along a direction inclined to the direction from the rotating part 41 to the shielding part 42. It can be understood that the reinforcing part 44 has a first extension end and a second extension end. The first extension end is close to the rotating part 41, and the second extension end is far from the rotating part 41. The extension direction of the reinforcing part 44 forms an angle other than 90° with the rotation axis of the baffle 40 to realize the inclined guiding of the airflow discharged from the air outlet hole 202.

[0066] Figure 13 is a perspective view of the electronic device in some embodiments of the present application. As Figure 12 and Figure 13As shown, a socket 205 is provided on the second side portion 241 or the fourth side portion of some electronic devices for external connection to a communication device. At this time, by setting the reinforcing portion 44 to extend in a direction away from the socket 205 side with its second extension end, part of the airflow can be guided to the side away from the socket 205. For example, when the socket 205 is provided on the second side portion 241, the first extension end of the reinforcing portion 44 is close to the second side portion 241 and away from the fourth side portion, and the second extension end of the reinforcing portion 44 is close to the fourth side portion and away from the second side portion 241.

[0067] In addition to the air outlet hole 202, a socket 205 is also provided on the third side portion 242 of some electronic devices for external connection to a communication device. For example Figure 13 As shown, the socket 205 is provided in the middle of the third side portion 242, and the air outlet holes 202 are provided on both the left and right sides of the socket 205. At this time, by setting the reinforcing portion 44 to extend in a direction away from the socket 205 side with its second extension end, part of the airflow can be guided to the side away from the socket 205. For example, when the air outlet hole 202 is provided on the left side of the socket 205, the second extension end of the reinforcing portion 44 on the left baffle 40 is located on the right side of the first extension end of the reinforcing portion 44. In this way, the baffle 40 not only improves its own structural strength through the setting of the reinforcing portion 44, but also reduces the blowing towards the externally connected communication device, avoiding affecting the performance of the externally connected communication device.

[0068] There are various ways to set the transmission component 30. For example, the transmission component 30 includes two transmission parts respectively provided on the first structural member 10 and the second structural member 20. At this time, the limiting structure 60 can be provided on at least one transmission part, or can also be provided on the first structural member 10 or the second structural member 20. The transmission component 30 can also only include the transmission part provided on the first structural member 10. At this time, the limiting structure 60 can be provided on this transmission part, or can also be provided on the first structural member 10 or the second structural member 20. The following embodiments will respectively illustrate the above methods.

[0069] Figure 14 This is a partial cross-sectional view of the electronic device in some embodiments of the present application. As 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 drivingly 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 drivingly connected to the second transmission member 32. When the first structural member 10 moves between the intermediate position and the deployment limit position, the first transmission member 31 is disengaged from the driving connection with the second transmission member 32. In this way, when the first structural member 10 is between the intermediate position and the deployment limit position, the second transmission member 32 no longer receives the acting force applied by the first transmission member 31, and the limiting structure only needs to hold the current open position of the baffle 40, reducing the wear on the second transmission member 32.

[0070] Wherein, 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 is drivingly connected to the second transmission structure 322, and the baffle 40 is drivingly connected to 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 driving 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. Among them, the first structural member 10 and the second structural member 20 are rotationally connected through 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 can also be arranged at an angle with the rotation axis of the second shaft 321, such as being arranged at a 90° angle. At this time, both the first transmission structure 312 and the second transmission structure 322 can be bevel gears.

[0071] To shield the first transmission member 31, a notch can be formed on the first structural member 10, and the first transmission member 31 can be arranged 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. Optionally, the first transmission structure 312 includes a first rack 312a disposed on the first shaft 311. The first rack 312a extends along the circumferential direction of the first shaft 311, and the circumferential direction of the first shaft 311 refers to the direction around the rotation axis of the first shaft 311. The second transmission structure 322 includes a second rack 322a disposed on the second shaft 321. The second rack 322a extends along the circumferential direction of the second shaft 321, and the circumferential direction of the second shaft 321 refers to the 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 meshes with the second rack 322a to cause the second transmission member 32 to drive the baffle 40 to move 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 is separated from the second rack 322a.

[0072] Wherein, when the first structural member 10 moves from the closed position towards the intermediate position, the first shaft 311 drives the second shaft 321 to rotate through the meshing of the first rack 312a and the second rack 322a. At this time, the rotation of the second shaft 321 can be defined as a forward rotation. When the first structural member 10 moves from the intermediate position towards the closed position, the rotation of the second shaft 321 can be defined as a reverse rotation. The forward rotation of the second shaft 321 can drive the baffle 40 to move from the shielding position towards the open position, and the reverse rotation of the second shaft 321 can drive the baffle 40 to move from the open position towards the shielding position. It should be noted that the above forward and reverse directions are clockwise and counterclockwise respectively. As shown in the figure, the forward direction is the clockwise direction and the reverse direction is the counterclockwise direction.

[0073] 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 they are the same. Taking this central angle as s, the rotation angle of the first structural member 10 from the closed position to the intermediate position is also s. When the user normally uses the device, the first structural member 10 is generally rotated by 90° - 120°. At this time, the baffle 40 may already be in the open position to achieve the best heat dissipation effect of the electronic device, or the baffle 40 is already close to the open position to make the heat dissipation effect of the electronic device close to the best. 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° to ensure that when the electronic device is normally used, the baffle 40 is already in the open position.

[0074] In other embodiments, the central angles corresponding to the first rack 312a and the second rack 322a may also be different. At this time, 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 central angles corresponding to 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 greater 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 a sprocket, a screw and a nut, two rough surfaces, etc., which are not limited herein.

[0075] As Figure 14 shown, in some embodiments, the transmission assembly 30 further includes a rod chain 33. The rod chain 33 includes 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. Two ends of the second rod 332 are respectively rotatably connected to the other end of the first rod 331 and the shielding portion 42. In this way, the second transmission member 32 is connected to the shielding portion 42 through the first rod 331 and the second rod 332 in sequence. When the second shaft 321 rotates, the first rod 331 pushes or pulls the second rod 332 to move. The second rod 332 pushes or pulls the shielding portion 42 to rotate relative to the rotating portion 41, so as to realize the rotation of the baffle 40. This multi-rod structure can bypass some obstacles, has a certain flexibility, and can adapt to different spatial layouts and movement requirements to a certain extent. In addition, when the baffle 40 is suddenly stressed, this multi-rod structure can absorb a part of the impact force, reduce the damage to the transmission assembly 30, thereby improving the stability and reliability of the system and prolonging the service life of the equipment. This connection method can realize the transmission and amplification of force by reasonably designing parameters such as the length and angle of the rod.

[0076] In other embodiments, the rod chain 33 may further include more than three rods connected in transmission, which are not limited herein. The transmission assembly 30 may also realize the transmission connection between the second transmission member 32 and the baffle 40 through other transmission structures, such as other mechanical transmissions (such as belt transmission, chain transmission, gear transmission, worm transmission, etc.), fluid transmissions (hydraulic transmission, pneumatic transmission, etc.), electric transmissions (such as direct drive of an electric motor, power electronic transmission, etc.) and magnetic transmissions, etc., which are not limited herein.

[0077] Figure 15 is a partial three-dimensional structural diagram of the transmission assembly in one embodiment of the electronic device of the present application; Figures 16 to 20Partial cross-sectional views of the electronic device in the embodiments of the present application at different opening degrees, where Figure 16 the opening degree of the first structural member in Figure 17 is 0°, Figure 18 the opening degree of the first structural member in Figure 19 is 45°, Figure 20 the opening degree of the first structural member 10 in Figures 15 to 20 is 90°, and

[0078] the opening degree of the first structural member in Figure 16 is 180°. For ease of description, the opening degree of the first structural member 10 when it is in the middle position is 60°, that is, when the opening degree of the first structural member 10 is 60°, the baffle 40 is in the open position, and at this time the opening degree of the baffle 40 is 90°. In the following embodiments, reference is made to Figures 15 to 20 .

[0078] As one of the embodiments, the limiting structure 60 at least includes a first limiting portion 61 and a second limiting portion 62. The first limiting portion 61 is disposed on the first transmission member 31. The first limiting portion 61 can be fixedly connected to the first transmission member 31 or can move relatively under a certain external force, and no limitation is made here. The second limiting portion 62 is disposed on the second transmission member 32. The second limiting portion 62 can be fixedly connected to the second transmission member 32 or can move relatively under a certain external force, and no limitation is made 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 towards 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. 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 middle position and the unfolded 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 restricting the second limiting portion 62 by the first limiting portion 61, so as to limit the baffle 40. The first limiting portion 61 and the second limiting portion 62 are respectively disposed on the first transmission member 31 and the second transmission member 32, which is convenient for detection, maintenance and replacement, simplifies the installation process. When the limiting structure 60 is worn or stuck, only the transmission assembly 30 needs to be replaced, and there is no need to replace the first structural member 10 and the second structural member 20, which is convenient and fast, saves costs, and at the same time, the appropriate first limiting portion 61 and the second limiting portion 62 can be replaced according to actual needs.

[0079] Wherein, when the first structural member 10 moves between the middle position and the deployment limit position, the first limiting portion 61 can move along with the movement of the first transmission member 31. At this time, the first limiting portion 61 restricts the movement of the second limiting portion 62 during its own movement. During the above process, the first limiting portion 61 can also be restricted by the second structural member 20 and be stationary relative to the second structural member 20. At this time, the first limiting portion 61 is in transmission connection with the second limiting portion 62, and the stationary state of the first limiting portion 61 also makes the second limiting portion 62 in a stationary state, thereby restricting the movement of the second limiting portion 62.

[0080] Exemplarily, when the first structural member 10 moves between the middle position and the deployment limit position (such as Figure 19 ), the first limiting portion 61 is slidably connected to the second limiting portion 62. That is to say, the first limiting portion 61 moves along with the movement of the first transmission member 31. The first limiting portion 61 slides relative to the second limiting portion 62 during the movement, and can restrict the movement of the second limiting portion 62 during the sliding process, so that the windshield is limited to the open position. In this way, when the first structural member 10 rotates from the closed position through the middle position towards the deployment limit position, the first limiting portion 61 can achieve a sliding connection with the second limiting portion 62 without changing the motion state and the connection state with the first transmission member 31, with a smooth transition, avoiding the impact and vibration that may be generated by sudden braking, and at the same time reducing the wear between the first limiting portion 61 and the second limiting portion 62. At the same time, the first limiting portion 61 can accurately restrict the second limiting portion 62 from stopping the movement by slidably connecting with the second limiting portion 62, thereby realizing the accurate positioning of the second transmission member 32. The composition and cooperation mode of the limiting structure 60 are simple, do not rely on a complex electronic control system, are less affected by the environment, have high reliability, and have good repeatability.

[0081] Wherein, when the first structural member 10 rotates between the closed position and the middle position (such as Figure 16 ), the first limiting portion 61 and the second limiting portion 62 can 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 demarcation point between meshing and separating, and the first limiting portion 61 and the second limiting portion 62 are also at the demarcation point between separating and contacting. In other embodiments, when the first structural member 10 rotates between the closed position and the middle position, the first limiting portion 61 and the second limiting portion 62 can also always be in a transmission connection state, which is not limited here.

[0082] Specifically, the first limiting portion 61 is arranged 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 (such as Figure 15), the two can be spaced apart or connected, and there is no limitation here. The first limiting part 61 has a limiting surface 611, and the limiting surface 611 can be a curved surface or a flat surface. Among them, the first limiting part 61 can be a block structure convexly arranged on the circumferential side surface of the first shaft 311. At this time, the limiting surface 611 can be selected as the outer surface of the first limiting part 61 on the side far from the first shaft 311. The second limiting part 62 is arranged on the second shaft 321. The second limiting part 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, and there is no limitation here. The second limiting part 62 forms a limiting groove 621. Among them, the second limiting part 62 can be a block structure convexly arranged on the circumferential side surface of the second shaft 321. The second limiting part 62 is provided with a limiting groove 621 on its surface. The second limiting part 62 can also be a surface structure, and the surface structure encloses to form 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.

[0083] When the first structural member 10 moves between the middle position and the deployment limit position (such as Figures 17 to 20 ), at least a part of the first limiting part 61 is located in the limiting groove 621 to limit the rotation of the second limiting part 62 in at least one direction. It can be understood that when the first structural member 10 moves between the middle position and the deployment limit position, at least a part of the first limiting part 61 can be located on the moving path when the groove side wall directly above the first limiting part 61 rotates in the reverse direction. Therefore, the first limiting part 61 can at least limit the reverse rotation of the second limiting part 62, and further limit the baffle 40 in the open position. Among them, the first limiting part 61 restricting the rotation of the second limiting part 62 means restricting the reverse rotation of the second limiting part 62, or restricting the forward rotation and reverse rotation of the second limiting part 62. In this way, the position of the second limiting part 62 is accurately restricted by the sliding of the first limiting part 61 in the limiting groove 621, realizing the accurate positioning of the second limiting part 62. The structure is simple and the assembly is convenient. After the assembly is completed, only when it is necessary to limit the second limiting part 62, at least a part of the first limiting part 61 needs to be located in the limiting groove 621, reducing the requirement for the installation accuracy. In other embodiments, the first limiting part 61 may not be convexly arranged on the circumferential side surface of the first shaft 311, but be flush with the circumferential side surface of the first shaft 311 or concave in the circumferential side surface of the first shaft 311. The second limiting part 62 may not be convexly arranged on the circumferential side surface of the second shaft 321, but be flush with the circumferential side surface of the second shaft 321 or concave in the circumferential side surface of the second shaft 321, and there is no limitation here.

[0084] 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, and the limiting surface 611 can be matched and fitted with the groove wall of the limiting groove 621. In other words, when the first structural member 10 is between the middle position and the unfolding 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, that is, the dual restriction of the forward rotation and reverse rotation of the second limiting portion 62 is realized, thereby realizing the accurate positioning of the baffle 40. Among them, the above-mentioned cross sections all refer to the cross sections perpendicular to the rotation axis of the first shaft 311.

[0085] 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 only slidably connected with a portion of the groove wall surface on the positive side of the limiting groove 621, and the limiting surface 611 is spaced from the groove wall surface on the reverse side of the limiting groove 621. In this way, when the first structural member 10 is between the middle position and the unfolding limit position, the first limiting portion 61 can limit the reverse rotation of the second limiting portion 62. It should be noted that on the groove wall surface of the limiting groove 621, the contact portion that is slidably connected with the limiting surface 611 can be point contact, line contact, or surface contact, which is not limited here.

[0086] In this case, the baffle 40 can be kept in the open position under the action of gravity, and the limiting structure 60 can also be set to further include a third limiting portion 63 provided on the second structural member 20, and the third limiting portion 63 is used to limit the baffle 40 in the open position. The setting of the third limiting portion 63 can make up for the deficiency of the first limiting portion 61 in limiting the second limiting portion 62, and improve the reliability of limiting the baffle 40. There are many ways to set the third limiting portion 63, which are described by examples below.

[0087] like Figure 21 As shown, illustratively, when the baffle 40 is in the open position, the baffle 40 abuts against the third limit portion 63. At this time, the third limit portion 63 can be the hole wall of the air outlet 202, or can be other abuttable structures arranged on the second structural member 20. In this way, the third limit portion 63 can limit the baffle 40 from moving further away from the shielding position, thereby reducing the processing accuracy of the limit groove 621 and reducing the processing cost.

[0088] like Figure 22As shown, illustratively, when the baffle 40 is in the open position, the second transmission member 32 abuts against the third limit portion 63. In this way, the third limit portion 63 can limit the second shaft 321 from continuing to rotate in the forward direction. This arrangement can avoid acting on the baffle 40 and reduce the wear on the baffle 40.

[0089] 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 disposed on the second structural member 20. When the baffle 40 is in the open position, the second transmission member 32 may 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 may release the elastic engagement with the elastic structure under the force of the first transmission member 31, thereby achieving reverse rotation. The elastic structure is simple, convenient to set up, and low in cost. At the same time, it is convenient for the user to manually control the baffle 40 to reset to the shielding position. In this way, when the electronic device is turned off and the first structural member 10 is not rotated to the closed position, the baffle 40 may 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.

[0090] It should be noted that when the second transmission member 32 is elastically engaged with the elastic structure, the elastic structure may be being squeezed and deformed, or may have just been squeezed and deformed and has recovered to its original state, which is not limited here. The elastic engagement includes an interference fit, that is, when the baffle 40 is in the open position, the second transmission member 32 and the third limit portion 63 are relatively pressed and moved to form an interference fit, and the third limit portion 63 is slightly elastically deformed.

[0091] 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, which 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, and at this time the elastic structure or the baffle 40 undergoes elastic deformation.

[0092] Figure 23 FIG. 1 is a partial cross-sectional view of the electronic device of the present application in another embodiment. Figure 23As shown, as another implementation, the first limiting part 61 may not be arranged on the first transmission part, but on the first structural part 10. When the first structural part 10 rotates, it drives the first limiting part 61 to rotate synchronously. Among them, the first limiting part 61 may be arranged on one side edge of the first structural part 10 close to the rotating assembly. The second limiting part 62 is arranged on the second transmission part 32, and the first limiting part 61 can limit the movement of the second limiting part 62. The structure and function of the first limiting part 61 may be the same as those of the first limiting part 61 installed on the first transmission part 31 in the above implementation, and the structure and function of the second limiting part 62 are also the same as those in the above implementation, which will not be elaborated here.

[0093] Figure 24 is a partial cross-sectional view of the electronic device of the present application in another embodiment. As Figure 24 shown, as another implementation, the limiting structure 60 includes a damping member 64. The damping member 64 is arranged between the second transmission part 32 and the second structural part 20. It can be understood that the damping member 64 can be arranged on the second transmission part 32 and abut against the second structural part 20. At this time, there is a damping force between the damping member 64 and the second structural part 20. The damping member 64 can also be arranged on the second structural part 20 and abut against the second transmission part 32. At this time, there is a damping force between the damping member 64 and the second transmission part 32. When the first structural part 10 is between the middle position and the unfolding limit position, the baffle 40 is stationary under the action of the damping force. Taking the damping member 64 arranged on the second transmission part 32 as an example, when the user drives the first structural part 10 to rotate between the closed position and the middle position, the damping member 64 can overcome the damping force with the second structural part 20 and rotate with the rotation of the second transmission part 32. When the first structural part 10 rotates past the middle position and enters the range between the middle position and the unfolding limit position, the first transmission part 31 and the second transmission part 32 are disengaged from the transmission connection, and the second transmission part 32 is stationary under the action of the damping force, so that the baffle 40 remains in the current open position. This setting can reduce the components of the limiting structure 60 and reduce the requirement for setting accuracy. Correspondingly, a damping structure 323 matching the damping member 64 can also be arranged on the second structural part 20 to increase the damping force between the two.

[0094] Optionally, the damping member 64 can be set so that the damping force first increases and then decreases when the first structural part 10 moves from the closed position towards the middle position. In this way, when the user opens the first structural part 10, the applied force needs to be increased first to improve the operation feel and avoid accidental opening of the first structural part 10, and then the applied force is reduced so that the user can easily adjust the angle of the first structural part 10 in the use state, and at the same time avoid too obvious damping change when passing the middle position.

[0095] The damping member 64 can be optionally the first torsion structure 64a, and the first torsion structure 64a can provide torsion for the rotation of the second transmission member 32. Figure 25 It is a partial assembly structure diagram of the transmission assembly in one embodiment of the electronic device of the present application. As Figure 25 shown, specifically, the first torsion structure 64a includes a shaft rod 641, a disc spring group 642, and a concave-convex group 643 provided 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, and the second tooth block 6432 has a corrugated second arc surface. Both the first tooth block 6431 and the second tooth block 6432 are connected to the shaft rod 641. Among them, 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, and the first arc surface and the second arc surface face each other and are abutted under the elastic force of the disc spring group 642. One of the disc spring group 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 arc surface and the second arc surface are matched and fitted, that is, the wave crest of the first arc surface corresponds to the wave trough of the second arc surface, and the wave trough of the first arc surface corresponds to the wave crest of the second arc surface. When the first transmission member 31 drives the second transmission member 32 to rotate, the wave crest of the first arc surface moves towards the wave crest of the second arc surface, the first tooth block 6431 presses the disc spring group 642, the disc spring group 642 is compressed and deformed, the elastic force applied to the first tooth block 6431 increases, and then the abutting force of the first tooth block 6431 on the second tooth block 6432 also increases, and the damping force of the first structural member 10 increases during the rotation towards the middle position. The second tooth block 6432 continues to rotate, the wave crest of the first arc surface crosses the wave crest of the second arc surface and moves towards the next wave trough, the disc spring group 642 elongates, releases the elastic force, the abutting force of the first tooth block 6431 on the second tooth block 6432 decreases, and the damping force of the first structural member 10 decreases. In this way, the damping force received by the first structural member 10 is increased first and then decreased. It should be noted that a first torsion structure 64a may not be provided between the first structural member 10 and the second structural member 20, but the change of torsion is realized through the damping member 64, or another identical or different first torsion structure 64a may be additionally provided, which is not limited here.

[0096] Figure 26 It is a partial cross-sectional view of the electronic device of the present application in another embodiment. As Figure 26As shown, as another implementation, the limit structure 60 further includes an elastic part 65. The first limit part 61 can be elastically connected to the first transmission part 31 through the elastic part 65. When the first structural part 10 moves between the closed position and the intermediate position, the first limit part 61 and the second limit part 62 do not interact, that is, the first limit part 61 and the second limit part 62 are spaced apart. The third limit part 63 is provided on the second structural part 20, and the third limit part 63 is used to limit the forward rotation of the second transmission part 32 when the first structural part 10 is in the intermediate position. The first limit part 61 has a first abutting surface and a second abutting surface. When the first structural part 10 reaches the intermediate position, the first limit part 61 abuts against the second limit part 62 in the opposite direction of the second limit part 62 through the first abutting surface, and the first limit part 61 abuts against the second structural part 20 through the second abutting surface. The second structural part 20 can limit the movement of the second abutting surface of the first limit part 61. Correspondingly, the movement of the second abutting surface of the first limit part 61 is also limited, so as to prevent the second limit part 62 from rotating in the reverse direction, and the second transmission part 32 is limited to the current position, so that the baffle 40 is kept in the open position. When the first structural part 10 continues to move towards the deployment limit position, the elastic part 65 undergoes elastic deformation, but the positions of the first abutting surface and the second abutting surface of the first limit part 61 remain unchanged. When the first structural part 10 rotates from the deployment limit position towards the intermediate position, the elastic part returns to its original state under the action of its own elastic restoring force. When the first structural part 10 rotates past the intermediate position and enters the area between the closed position and the intermediate position, the first abutting surface of the first limit part 61 separates from the second limit part 62, and the second abutting surface of the first limit part 61 separates from the second structural part 20. In this way, the first limit part 61 not only realizes the limitation of the second limit part 62, but also when the user moves the first structural part 10 from the intermediate position towards the deployment limit position, due to the gradual increase in the deformation of the elastic part 65, the force applied by the user also gradually increases, thereby increasing the operating feel and preventing the user from applying too much force unconsciously when the first structural part 10 is close to the deployment limit position, resulting in excessive force on the first structural part 10 when it reaches the deployment limit position and causing damage to the first structural part 10.

Among them, the plane where the plate portion 352 is located can be parallel to the display surface 10a1 of the first structural member 10 to achieve thinning of the first structural member 10.

[0100] Optionally, a second torsion structure 36 may be provided at one end of the shaft portion 3111 away from the connecting member 35. The specific structure of the second torsion structure 36 is the same as that of the first torsion structure 64a serving as the damping member 64 in the above embodiment, and will not be elaborated here. At this time, the shaft rod of the second torsion structure 36 is connected to the shaft portion 3111, and the disc spring group is connected to the first structural member 10.
