Description

Technical Field

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

[0002] With the advancement of science and technology, electronic devices are now developing in the direction of multi-function, high speed and miniaturization. The integration of some electronic components in electronic devices, such as system on chip (SOC), central processing unit (CPU), graphics processing unit (GPU) and other components is getting higher and higher, resulting in a significant increase in the power consumption density of components, which in turn greatly increases the heat of electronic devices. Electronic devices will experience obvious losses when running at high temperatures, reducing product performance.

[0003] In order to solve the above problems, a heat dissipation method is usually adopted, such as using air cooling to cool down the heating components inside the electronic device. However, the above air cooling method may cause the problem of poor air flow, thereby reducing the heat dissipation efficiency. Summary of the invention

[0004] The present application provides an electronic device for alleviating the problem of poor air flow when heat is dissipated by air cooling.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In one aspect of the present application, an electronic device is provided, which includes a display screen, a host housing, a heat dissipation device, an air duct structure, and a driving mechanism. The host housing has a receiving cavity, the host housing is rotatably connected to the display screen, and a mounting hole connected to the receiving cavity is provided at one end of the host housing facing the display screen. The heat dissipation device is arranged in the receiving cavity, and the heat dissipation side of the heat dissipation device faces the mounting hole. At least a part of the air duct structure is located in the mounting hole and on the heat dissipation side of the heat dissipation device, and the air duct structure is rotatably connected to the host housing. The air duct structure includes an air outlet, and the air outlet is connected to the heat dissipation side of the heat dissipation device and the mounting hole. In addition, the driving mechanism is arranged in the receiving cavity and is transmission-connected to the air duct structure, and the driving mechanism is slidably matched with the host housing. If the display screen rotates to a first preset angle α relative to the host housing, the driving mechanism is transmission-connected to the display screen, and the driving mechanism is used to slide in the direction toward the display screen when the display screen rotates, and drive the air duct structure to rotate, and the rotation direction of the air outlet is the same as the rotation direction of the display screen.

[0007] As can be seen from the above, the display screen is rotatably connected to the host shell, and the display screen is transmission-connected to the driving mechanism, so when the display screen rotates to the first preset angle α relative to the host shell, the display screen can drive the driving mechanism to slide relative to the host shell toward the display screen during the rotation process, so that the rotational motion of the display screen can be converted into the linear motion of the driving mechanism. On this basis, since the air duct structure is rotatably connected to the host shell, and the driving mechanism is transmission-connected to the air duct structure, the driving mechanism can drive the air duct structure to rotate relative to the host shell during the sliding process, so as to convert the linear motion of the driving mechanism into the rotational motion of the air duct structure, so that the air duct structure rotates in the same direction as the display screen. In this way, when the display screen rotates to the first preset angle relative to the host shell, the air duct structure can be driven by the driving mechanism to rotate in the same direction as the display screen, so that the air outlet of the air duct structure can be tilted downward toward the direction of the desktop, so that the air outlet can avoid the rotating shaft, reduce the probability of the rotating shaft blocking the air outlet, or make the rotating shaft not block the air outlet, so that the heat exchanged by the heat dissipation device can be effectively discharged from the host shell.

[0008] In an optional embodiment, the electronic device further comprises a pin shaft. The pin shaft is located in the accommodating cavity, the first end of the pin shaft is rotatably connected to the host housing, and the second end of the pin shaft is connected to the display screen. In addition, the driving mechanism comprises a linear transmission part, a first transmission part and a second transmission part. Among them, the linear transmission part is slidably matched with the host housing. The first transmission part is arranged on the linear transmission part, the first transmission part is transmission-connected to the pin shaft, and the first transmission part is used to convert the rotational motion of the pin shaft into the linear motion of the linear transmission part. The second transmission part is arranged on the linear transmission part, the second transmission part is transmission-connected to the air duct structure, and the second transmission part is used to convert the linear motion of the linear transmission part into the rotational motion of the air duct structure. In this way, when the display screen rotates, the first transmission part converts the rotational motion of the display screen into the linear motion of the linear transmission part, and the second transmission part can convert the linear motion of the linear transmission part into the rotational motion of the air duct structure, so that the air duct structure can rotate in the same direction as the display screen.

[0009] In an optional embodiment, the linear transmission part may include a rack, and the extension direction of the rack is the same as the sliding direction of the linear transmission part. The first transmission part may include a first gear, which can be engaged with one end of the rack toward the pin shaft and connected to the pin shaft. In addition, the second transmission part includes a second gear, which can be engaged with one end of the rack away from the pin shaft. The second gear can also be connected to the air duct structure. In this way, the rotation of the pin shaft can drive the first gear to rotate, and then the first gear can drive the rack to slide toward the pin shaft, thereby driving the second gear to rotate in the same direction as the first gear. Since the second gear is connected to the air duct structure, and the air duct structure is rotationally connected to the main body housing, the rack can drive the air duct structure to rotate in the same direction as the first gear through the second gear.

[0010] In an optional embodiment, the electronic device further comprises a protrusion, which is located in the accommodating cavity and is arranged on the pin shaft to be connected with the pin shaft. The linear transmission part comprises a transmission rod, and the extension direction of the transmission rod is the same as the sliding direction of the linear transmission part. The first transmission part comprises a transmission groove, which is arranged at one end of the transmission rod facing the pin shaft, and the opening of the transmission groove faces the pin shaft; the protrusion is slidably matched with the transmission groove, and if the display screen rotates to a first preset angle α relative to the host, the protrusion abuts against the groove wall of the transmission groove on the side away from the transmission rod. The second transmission part comprises a first guide groove, which is arranged at one end of the transmission rod away from the pin shaft, and the guiding direction of the first guide groove is perpendicular to the extension direction of the transmission rod and the extension direction of the pin shaft; the air duct structure is slidably matched with the first guide groove. In this way, by arranging the protrusion on the pin shaft, intermittent transmission connection can be achieved between the drive mechanism and the display screen, and between the drive mechanism and the air duct structure. For example, when the display screen is closed on the host housing, or when the display screen rotates to the second preset angle β relative to the host housing, and β<α, the angle between the display screen and the host housing is small, the probability of the rotating shaft blocking the air outlet of the air duct structure is small, the driving mechanism and the display screen are in a state of non-transmission connection, and the driving mechanism and the air duct structure are in a state of non-transmission connection. At this time, the air duct structure does not need to rotate with the display screen. In addition, when the display screen rotates from the second preset angle β to the first preset angle α relative to the host housing, the angle between the display screen and the host housing is large. The protrusion abuts against the groove wall of the transmission groove, so that the display screen can be transmission-connected to the driving mechanism through the protrusion. Therefore, when the pin drives the protrusion to continue to rotate, the protrusion can drive the linear transmission part to slide toward the pin. In this case, the first guide groove will also slide toward the pin, so that the driving mechanism is transmission-connected to the air duct structure, and the air duct structure can slide upward in the first guide groove while also sliding toward the pin following the first guide groove, so that the purpose of the air duct structure rotating in the same direction as the display screen is achieved. In this way, the display screen can be rotated to drive the driving mechanism to move linearly, and then the driving mechanism can drive the air duct structure to rotate in the same direction as the display screen to avoid being blocked by the rotating shaft. Based on this, by setting an intermittent transmission connection between the driving mechanism and the display screen, and between the driving mechanism and the air duct structure, it is not necessary to drive the air duct structure to rotate together with the driving mechanism when the display screen starts to rotate, thereby reducing the sliding stroke of the driving mechanism, which is conducive to increasing the component space inside the host shell.

[0011] In an optional embodiment, the electronic device further comprises a first connecting member, the first connecting member is located between the transmission rod and the air duct structure, and is connected to the air duct structure, and a portion of the first connecting member is located in the first guide groove and is slidably matched with the first guide groove. In addition, the first connecting member is rotatably connected to the host housing. In this way, since the first connecting member is connected to the air duct structure and is rotatably connected to the host housing, the air duct structure can be indirectly rotatably connected to the host housing through the first connecting member. In addition, the first connecting member is also slidably matched with the first guide groove, so the air duct structure can be indirectly slidably matched with the first guide groove through the first connecting member.

[0012] In an optional embodiment, the first connecting member includes a first sliding rod, a first rotating rod and a first connecting plate. The first end of the first sliding rod is located in the first guide groove, and the first end of the first sliding rod is slidably matched with the first guide groove. The first end of the first rotating rod is rotatably connected to the host housing, and the second end of the first rotating rod is connected to the air duct structure. The first connecting plate is arranged between the first sliding rod and the first rotating rod, and the first connecting plate is connected to the first sliding rod and the first rotating rod. In this way, the rigidity of the entire first connecting member can be improved by the first connecting plate. In this case, the air duct structure can be slidably matched with the first guide groove through the first sliding rod, so that the first sliding rod drives the air duct structure to slide along the guide direction of the first guide groove. In addition, the air duct structure can be rotatably connected to the host housing through the first rotating rod, so that the air duct structure and the display screen can rotate in the same direction under the drive of the driving mechanism.

[0013] In an optional embodiment, the host housing includes an upper cover plate and a lower cover plate. The lower cover plate includes a lower cover plate body and a warping portion. The lower cover plate body and the upper cover plate are stacked. The warping portion is arranged between the lower cover plate body and the upper cover plate, and is arranged on the side where the air duct structure is located. The warping portion is connected to the upper cover plate and the lower cover plate body, and the mounting hole is opened on the warping portion. Since the warping portion is arranged between the lower cover plate body and the upper cover plate, and is connected to the upper cover plate and the lower cover plate body, the warping portion can provide the height of the accommodating cavity along the Z direction. In addition, the warping portion is arranged on the side where the air duct structure is located, so the mounting hole is opened on the warping portion, which can facilitate the heat from the air duct structure to be discharged into the external space of the electronic device. Among them, if the display screen is rotated from 0° to a second preset angle β relative to the host housing, the driving mechanism is not in transmission connection with the display screen, and the air outlet direction of the air outlet is parallel to the plate surface of the upper cover plate, β<α. Based on this, if the display screen rotates from the second preset angle β to the first preset angle α relative to the host housing, the sliding direction of the first sliding rod in the first guide groove points from the lower cover plate body to the upper cover plate, the first connecting member drives the air duct structure to rotate clockwise, and the air outlet direction of the air outlet is away from the upper cover plate. Based on this, by setting an intermittent transmission connection between the drive mechanism and the display screen, and between the drive mechanism and the air duct structure, it is not necessary to drive the air duct structure to rotate together with the drive mechanism when the display screen starts to rotate, thereby reducing the sliding stroke of the drive mechanism, which is conducive to increasing the component space inside the host housing.

[0014] In an optional embodiment, the range of the second preset angle β is: 0°≤β≤90°, where β<α. When the display screen is rotated relative to the host housing to an angle range of 0°≤β≤90°, the angle between the display screen and the host housing is small, and the rotating shaft basically does not block the air outlet of the air duct structure.

[0015] In an optional embodiment, the vertical projection of the pin on the warping portion does not overlap with the position of the mounting hole, and the vertical projection of the pin on the warping portion is arranged close to the upper cover relative to the position of the mounting hole. In this way, when the display screen is closed on the host housing, or the display screen rotates at a small angle relative to the host housing, such as the second preset angle β, the shaft will not block the air outlet of the air duct structure when the air duct structure does not need to rotate with the display screen.

[0016] In an optional embodiment, the electronic device further includes a pin connector and a swivel bearing frame. The pin connector is located in the accommodating chamber and connected to the main body housing; the first end of the pin is located in the pin connector and is rotatably connected to the pin connector. The swivel bearing frame is located in the accommodating chamber and connected to the pin connector, and the swivel bearing frame is slidably engaged with the linear transmission part. In this case, since the pin connector is rotatably connected to the pin, the display screen can be indirectly rotatably connected to the main body housing through the pin and the pin connector. In addition, the swivel bearing frame is slidably engaged with the linear transmission part of the driving mechanism, so that the linear transmission part of the driving mechanism can be indirectly slidably engaged with the main body housing through the swivel bearing frame.

[0017] In an optional embodiment, the electronic device further includes a guide post, which is disposed on the swivel bearing frame and connected to the swivel bearing frame. In addition, the driving mechanism further includes a second connecting plate, which is disposed on the swivel bearing frame and connected to the linear transmission part; a second guide groove is provided on the second connecting plate, and the guiding direction of the second guide groove is the same as the sliding direction of the linear transmission part, and the guide post is provided in the second guide groove and slidably cooperates with the second guide groove. In this way, by providing the guide post on the swivel bearing frame and providing the second connecting plate connected to the linear transmission part on the linear transmission part, the guide post can slide in the second guide groove provided on the second connecting plate during the linear movement of the linear transmission part, so that the sliding direction of the linear transmission part is consistent with the guiding direction of the second guide groove.

[0018] In an optional embodiment, the electronic device further comprises an elastic member, the first end of which is connected to an end of the linear transmission part away from the pin shaft, and the second end of the elastic member is connected to the host housing. In this way, when the angle between the display screen and the host housing is the first preset angle α (90°≤α≤150°), the pin shaft rotates clockwise, and the protrusion abuts against the groove wall of the transmission groove. At this time, the driving mechanism is connected to the protrusion in a transmission manner so that the driving mechanism slides toward the pin shaft to drive the air duct structure to rotate clockwise. At this time, the elastic member is in a stretched state. In addition, when the angle between the display screen and the host housing is the second preset angle β (0°≤β≤90°), the pin shaft rotates counterclockwise, and the protrusion no longer abuts against the groove wall of the transmission groove. At this time, the driving mechanism is not connected to the protrusion in a transmission manner, and the elastic force recovery action of the elastic member causes the driving mechanism to slide away from the pin shaft to drive the air duct structure to rotate counterclockwise and reset.

[0019] In an optional embodiment, the electronic device further comprises a rotating bearing frame, and the rotating bearing frame is slidably matched with the linear transmission part. The second end of the elastic member is connected to the rotating bearing frame, and an avoidance groove is provided on the rotating bearing frame, and the vertical projection of the elastic member on the plate surface of the rotating bearing frame overlaps with the avoidance groove. In this way, when the elastic member is stretched and contracted, interference between the rotating bearing frame and the elastic member is avoided.

[0020] In an optional embodiment, the bottom of the transmission groove is a first arc surface, and the curvature of the first arc surface is the same as the curvature of the surface of the pin. The transmission groove passes through the transmission rod on the side away from the pin. In this way, when the pin drives the protrusion to rotate, it can slide into the transmission groove from the lower side of the transmission groove, thereby slidingly cooperating with the transmission groove.

[0021] In an optional embodiment, a limiting groove is provided at one end of the transmission rod facing the pin, and the opening of the limiting groove faces the pin. At least a portion of the groove bottom of the limiting groove is a second arc surface, the second arc surface has the same curvature as the surface of the pin, and the second arc surface and the first arc surface are concentrically arranged. The depth of the limiting groove is less than the depth of the transmission groove. If the display screen rotates to a third preset angle γ relative to the host housing, the pin abuts against the second arc surface, wherein γ>α. Based on this, if the display screen rotates to a third preset angle γ relative to the host housing, the pin can abut against the second arc surface, thereby preventing the transmission rod from moving further toward the pin, thereby limiting the air duct structure 30. Since the second arc surface has the same curvature as the surface of the pin, the contact area between the second arc surface and the pin can be increased, effectively ensuring the limiting effect of the limiting groove on the transmission rod.

[0022] In an optional implementation, the range of the third preset angle γ is: 130°≤γ≤155°. When the angle between the display screen and the host housing is less than 130°, the display screen is still within the range of the user's optimal viewing angle. When the angle between the display screen and the host housing is greater than 155°, the opening angle of the display screen is too large, and the damping structure connected to the shaft will be affected under the gravity of the display screen itself. Therefore, the maximum viewing opening angle of the display screen can be limited to the range of 130°≤γ≤155°.

[0023] In an optional embodiment, the electronic device further includes a guide member and a second connecting member. The guide member is disposed at one end of the air duct structure facing away from the linear transmission portion, the guide member is connected to the main body housing, a third guide groove is disposed on the guide member, and the guiding direction of the third guide groove is the same as the rotation direction of the air duct structure. The second connecting member is located between the guide member and the air duct structure and is connected to the air duct structure, a portion of the second connecting member is located in the third guide groove and is slidably engaged with the third guide groove; the second connecting member is rotatably connected to the guide member. In this way, since the second connecting member is connected to the air duct structure and is rotatably connected to the main body housing through the guide member, the air duct structure can be indirectly rotatably connected to the main body housing through the second connecting member and the guide member. In addition, the second connecting member is also slidably engaged with the third guide groove, so the air duct structure can be indirectly slidably engaged with the third guide groove through the second connecting member.

[0024] In an optional embodiment, the second connecting member includes a second sliding rod, a second rotating rod and a third connecting plate. The first end of the second sliding rod is located in the third guide groove, and the first end of the second sliding rod is slidably matched with the third guide groove. The first end of the second rotating rod is rotationally connected to the guide member, and the second end of the second rotating rod is connected to the air duct structure. The third connecting plate is arranged between the second sliding rod and the second rotating rod, and the third connecting plate is connected to the second sliding rod and the second rotating rod. The rigidity of the entire second connecting member is improved by the second connecting member. In this case, the air duct structure can be slidably matched with the third guide groove through the second sliding rod, so that the second sliding rod drives the air duct structure to slide along the guide direction of the third guide groove. In addition, the air duct structure can be rotationally connected to the host housing through the second rotating rod, so that the air duct structure and the display screen can rotate in the same direction under the drive of the driving mechanism.

[0025] In an optional embodiment, the range of the first preset angle α is: 90°≤α≤150°. When the angle between the display screen and the host housing is too small, for example, less than 90°, or the angle between the display screen and the host housing is too large, for example, greater than 150°, the user cannot see the complete display surface of the display screen. Therefore, when the angle between the display screen and the host housing is within the range of 90°≤α≤150°, the display surface of the display screen can be fully displayed in front of the user during the user's use of the electronic device, which is convenient for the user to watch. In this case, when the first preset angle α is within the above range, the display screen can be at a more ideal observation angle, and the electronic device can be in a state of being used. At this time, the air duct structure is driven by the driving mechanism and rotates in the same direction as the display screen, so that the electronic device can be effectively cooled during the user's use of the electronic device, thereby improving the user's experience.

[0026] In an optional embodiment, a portion of the air duct structure is embedded in the mounting hole so that the air outlet of the air duct structure can be connected to the mounting hole. In this way, the air outlet of the air duct structure can have a guiding function to transfer the heat from the heat dissipation side of the heat dissipation device to the external environment of the electronic device through the air outlet of the air duct structure.

The top cover 111 and the front frame 112 are connected to form a cavity, and the screen body 110 is disposed in the cavity formed by the top cover 111 and the front frame 112. The top cover 111 is located on the back of the screen body 110, the front frame 112 is located on the side where the display surface of the screen body 110 is located, and a mounting hole for exposing the display surface of the screen body 110 is provided on the front frame 112.

[0075] For example, the screen body 110 may be a liquid crystal display (LCD), an organic light emitting diode (OLED), or a micro or mini light emitting diode (LED). The embodiment of the present application does not limit the type of the screen body 110.

[0076] Continue as Figure 1AAs shown, it can be known from the above that the host 10 and the display screen 11 are rotatably connected, so that the display screen 11 can rotate around the X-axis relative to the host 10, so as to realize the opening and closing of the display screen 11. For the convenience of explanation below, an XYZ coordinate system with the electronic device 01 is established in the accompanying drawings. The above X-axis can be the direction of the rotation axis of the display screen 11 when the display screen 11 rotates relative to the host 10, and can also be called the length direction of the electronic device 01. The Y-axis is a direction perpendicular to the X-axis. When the display screen 11 is closed on the host 10, the plane formed by the X-axis and the Y-axis can be parallel or approximately parallel to the display surface of the display screen 11. In addition, the Z-axis can be the thickness direction of the electronic device 01, such as Figure 1B As shown, when the display screen 11 is closed on the host 10, the display screen 11 is stacked on the host 10 along the Z axis.

[0077] The following is an example of the closed and open states of the display screen 11. Figure 1B As shown, in the initial state, the display screen 11 can be closed (or buckled) on the host 10. At this time, Figure 1A The front frame 112 of the display screen 11 and the upper cover 1011 of the host 10 can be parallel or in contact with each other, and the angle between the host 10 and the display screen 11 can be 0° or close to 0°. Figure 1A When the display screen 11 is rotated along the X-axis as shown, the angle between the display screen 11 and the host 10 can be increased, so that the display screen 11 is in an open state, so that the user can see the picture displayed on the display screen 11. In the embodiment of the present application, the display screen 11 can rotate relative to the host 10 at an angle of 0° to 180°.

[0078] In addition, continue as Figure 1A As shown, the host 10 may include a host housing 101, and the host housing 101 may be rotatably connected to the display screen 11, so that the entire host 10 is rotatably connected to the display screen 11. The host housing 101 may include an upper cover plate (also referred to as a C shell) 1011 and a lower cover plate (also referred to as a D shell) 1012 that are arranged opposite to each other, and the upper cover plate 1011 is arranged relative to the lower cover plate 1012 and close to the display screen 11. Among them, the upper cover plate 1011 and the lower cover plate 1012 may form a Figure 2A In addition, the electronic device 01 may further include a keyboard and a control panel (not shown) disposed on the upper cover 1011 and a housing cavity 1013 (such as Figure 2A The processor (not shown in the figure) can control the screen body 110 to display.

[0079] For example, the processor may include one or more processing units, for example, the processor may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). Different processing units may be independent devices or integrated into one or more processors. In addition, the electronic device 01 may also include an external memory interface, an internal memory, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a mobile communication module, a wireless communication module, an audio module, a speaker, a receiver, a microphone, a headphone interface, a sensor module, a button, and a camera. The sensor module may include a pressure sensor, a gyroscope sensor, an air pressure sensor, a magnetic sensor, an acceleration sensor, a distance sensor, a proximity light sensor, a fingerprint sensor, a temperature sensor, a touch sensor, an ambient light sensor, and a bone conduction sensor.

[0080] In some embodiments of the present application, the processor may be used as a heating element and may generate a large amount of heat during operation. In order to dissipate the heat of the heating element, the electronic device 01 may further include: Figure 2B The heat sink 20 shown. In some embodiments of the present application, the heat sink 20 may be an air-cooled heat sink. For example, the heat sink 20 may include a heat conductive sheet 201, a heat pipe 202, a fan 203, and heat sink fins 204. The heat conductive sheet 201 may be a metal sheet or a heat spreader with good thermal conductivity, and the heat conductive sheet 201 may be connected to the heating element through a heat conductive medium. The heat conductive sheet 201 is also connected to the first end of the heat pipe 202, and the second end of the heat pipe 202 may be connected to the air outlet side of the fan 203 and the heat sink fins 204. For example, the heat pipe 202 may be made of at least one of copper or aluminum. The heat spreader may be made of at least one of copper, aluminum, or stainless steel.

[0081] In this way, the heat of the heating element can be transferred to the first end of the heat pipe 202 through the heat conductive sheet 201, so that the working medium in the heat pipe is vaporized, and the vaporized working medium flows along the extension direction of the heat pipe 202 to the second end of the heat pipe 202. The airflow generated by the fan 203 can exchange heat with the heat at the second end of the heat pipe 202, and increase the heat dissipation surface area through the heat dissipation fins 204. Finally, the heat exchanged between the heating element and the heat dissipation device 20 will be taken out of the host housing 101 (such as Figure 2A In addition, after the working fluid at the second end of the heat pipe 202 is cooled by the fan 203, it flows back to the first end of the heat pipe 202 for the next heat cycle. The above is an example of the heat dissipation device 20, and does not constitute a limitation on the structure and quantity of the heat dissipation device 20. In other embodiments of the present application, the heat dissipation device 20 may also include a vacuum chamber (VC) and a pump and other components, which are not described in detail in this application.

[0082] On this basis, in order to be able to bring the heat exchanged between the heating element and the heat dissipation device 20 out of the host housing 101, in some embodiments of the present application, such as Figure 3 As shown, the electronic device 01 may further include an air duct structure 30 and a driving mechanism 40 , and the air duct structure 30 and the driving mechanism 40 may both be disposed in the accommodating cavity 1013 of the host housing 101 .

[0083] In addition, if Figure 4A As shown, the host housing 101 faces the display screen 11 (as shown in FIG. Figure 3 The mounting hole 100 connected to the accommodating cavity 1013 is provided at one end of the main body housing 101, and the mounting hole 100 can penetrate the main body housing 101, so that the accommodating cavity 1013 of the main body housing 101 is connected to the external environment of the electronic device 01. The heat dissipation side of the heat dissipation device 20 (the side where the multiple arrows arranged side by side in the figure) faces the mounting hole 100. For example, the heat dissipation device 20 includes Figure 2B In the case of the fan 203 shown, the heat dissipation side of the heat dissipation device 20 may be the air outlet side of the fan 203 , that is, the air outlet side of the fan 203 faces the mounting hole 100 .

[0084] As can be seen from the above, the host housing 101 includes: Figure 4AThe upper cover plate 1011 and the lower cover plate 1012 are shown. In some embodiments of the present application, the lower cover plate 1012 may include a lower cover plate body 10121 and a tilting portion 10122 connected as an integral structure. Among them, the lower cover plate body 10121 can be stacked with the upper cover plate 1011. The tilting portion 10122 is arranged between the lower cover plate body 10121 and the upper cover plate 1011. In addition, the tilting portion 10122 is arranged on the side where the air duct structure 30 is located, and the tilting portion 10122 can be connected to the upper cover plate 1011 and the lower cover plate body 10121, and the above-mentioned mounting hole 100 can be opened on the tilting portion 10122.

[0085] In this way, if Figure 4B As shown, since the warping portion 10122 is disposed between the lower cover body 10121 and the upper cover 1011, and is connected to the upper cover 1011 and the lower cover body 10121, the warping portion 10122 can provide a height of the accommodating cavity 1013 along the Z direction. Figure 4A As shown, the raised portion 10122 is disposed on the side where the air duct structure 30 is located, so the mounting hole 100 is opened on the raised portion 10122, which can facilitate the discharge of heat from the air duct structure 30 to the external space of the entire electronic device 01.

[0086] In addition, if Figure 5 (along Figure 3 As shown in the cross-sectional view obtained by the dotted line Q1-Q1 in the figure, the air duct structure 30 can be located on the heat dissipation side of the heat dissipation device 20. For example, when the heat dissipation device 20 includes a fan 203, the air duct structure 30 can be located on the air outlet side of the fan 203 (the side where the thick solid arrow is located in the figure). In addition, when the heat dissipation device 20 also includes a heat pipe 202 and a heat conductive sheet 201, the end of the heat pipe 202 connected to the fan 203 can be located between the air outlet side of the fan 203 and the air duct structure 30, so that the airflow generated by the fan 203 can discharge the heat from the heat pipe 202 to the air duct structure 30, so as to improve the heat dissipation efficiency.

[0087] Continue as Figure 5 As shown, the air duct structure 30 may include an air outlet 301, and the air outlet 301 is connected to the heat dissipation side (in the direction indicated by the arrow in the figure) of the heat dissipation device 20 and Figure 4A The mounting hole 100 is shown. For example, during the installation process, at least a portion of the duct structure 30 can be embedded in the Figure 4A The air outlet 301 of the air duct structure 30 can be connected to the mounting hole 100. Figure 5As shown, the air outlet 301 of the air duct structure 30 can have a guiding function to transfer the heat from the heat dissipation side of the heat dissipation device 20 to the external environment of the electronic device 01 through the air outlet 301 of the air duct structure 30.

[0088] In some embodiments of the present application, Figure 6 As shown, the air duct structure 30 may be strip-shaped and have a plurality of air outlets 301 arranged side by side, so that the air duct structure 30 may be a grid structure. In this way, the heat from the heat dissipation side of the heat dissipation device 20 may not only be transmitted to the external environment of the electronic device 01 through the plurality of air outlets 301 of the air duct structure 30, but also may be transmitted to the external environment of the electronic device 01 through the plurality of air outlets 301 of the air duct structure 30. Figure 6 The retaining wall 302 between two adjacent air outlets 301 of the air duct structure 30 shown in the figure blocks dust from the external environment and reduces dust ingress. Figure 5 The probability of being within the accommodating cavity 1013 of the host housing 101 is shown.

[0089] On this basis, continue Figure 5 As shown, the air duct structure 30 can be rotatably connected to the host housing 101. For example, the rotation direction of the air duct structure 30 relative to the host housing 101 can be the same as the rotation direction of the display screen 11 relative to the host housing 101. In this case, since the display screen 11 can be rotated along Figure 5 The air duct structure 30 can be rotated relative to the main body housing 101 in the direction of the arrow shown in the figure to open and close the display screen 11. Figure 5 The arrow direction shown is rotation relative to the host housing 101. For example, the electronic device 01 may include a rotating shaft 50, and the display screen 11 may be rotatably connected to the host housing 101 via the rotating shaft 50.

[0090] In addition, continue as Figure 5 As shown, the driving mechanism 40 is disposed in the accommodating cavity 1013 and is transmission-connected with the air duct structure 30 and the display screen 11. In the embodiment of the present application, the transmission connection refers to a connection relationship between two transmission-connected components, in which the active component performs mechanical movement (movement or rotation) while driving the driven component to perform mechanical movement (movement or rotation), thereby realizing mechanical transmission, including connection relationships such as snap-on, meshing, abutment, and sliding.

[0091] For example, the transmission connection between the drive mechanism 40 and the display screen 11 means that when the display screen 11 is an active component and the drive mechanism 40 is a driven component, the display screen 11 can drive the drive mechanism 40 to perform mechanical movement when the display screen 11 performs mechanical movement, thereby realizing mechanical transmission between the drive mechanism 40 and the display screen 11. Similarly, the transmission connection between the drive mechanism 40 and the air duct structure 30 means that when the drive mechanism 40 is an active component and the air duct structure 30 is a driven component, the drive mechanism 40 can drive the air duct structure 30 to perform mechanical movement when the drive mechanism 40 performs mechanical movement, thereby realizing mechanical transmission between the drive mechanism 40 and the air duct structure 30.

[0092] Based on this, in some embodiments of the present application, Figure 7 As shown, since the driving mechanism 40 is in transmission connection with the display screen 11, if the display screen 11 rotates to the first preset angle α relative to the host housing 101, the rotation of the display screen 11 can drive the driving mechanism 40 to move. In some embodiments, the driving mechanism 40 can be slidably matched with the host housing 101. For example, the driving mechanism 40 can slide toward or away from the display screen 11 along the Y direction relative to the host housing 101. Therefore, the driving mechanism 40 can slide in the direction (Y direction) toward (or away from) the display screen 11 when the display screen 11 rotates clockwise (or counterclockwise).

[0093] On this basis, since the driving mechanism 40 is connected to the air duct structure 30 by transmission, and the air duct structure 30 is rotatably connected to the host housing 101, the driving mechanism 40 can drive the air duct structure 30 to move along the direction (Y direction) toward (or away from) the display screen 11. Figure 7 The arrow in FIG. 1 rotates clockwise (or counterclockwise) so that the rotation direction of the air outlet 301 of the air duct structure 30 is the same as the rotation direction of the display screen 11.

[0094] As can be seen from the above, the display screen 11 is rotatably connected to the host housing 101, and the display screen 11 is transmission-connected to the driving mechanism 40. Figure 7 As shown, when the display screen 11 rotates to the first preset angle α relative to the host housing 101, the display screen 11 can drive the driving mechanism 40 to slide relative to the host housing 101 along the Y direction toward the display screen 11 during the rotation process, so that the rotational motion of the display screen 11 can be converted into the linear motion of the driving mechanism 40. On this basis, since the air duct structure 30 is rotationally connected to the host housing 101, and the driving mechanism 40 is transmission-connected to the air duct structure 30, the driving mechanism 40 can drive the air duct structure 30 to rotate relative to the host housing 101 during the sliding process, thereby converting the linear motion of the driving mechanism 40 into the rotational motion of the air duct structure 30, so that the air duct structure 30 and the display screen 11 rotate in the same direction.

[0095] In this way, if Figure 8 As shown, when the display screen 11 rotates to a first preset angle α relative to the host housing 101, the air duct structure 30 can be driven by the driving mechanism 40 to rotate in the same direction as the display screen 11, so that the air outlet 301 of the air duct structure 30 can be tilted downward toward the desktop (indicated by a shaded horizontal line in the figure), so that the air outlet 301 can avoid the rotating shaft 50, reducing the probability of the rotating shaft 50 blocking the air outlet 301, or making the rotating shaft 50 unobstructed to the air outlet 301, so that the heat exchanged by the heat dissipation device 20 can be effectively discharged from the host housing 101.

[0096] For example, the range of the first preset angle α can be: 90°≤α≤150°. When the angle between the display screen 11 and the host housing 101 is too small, for example, less than 90°, or the angle between the display screen 11 and the host housing 101 is too large, for example, greater than 150°, the user cannot see the complete display surface of the display screen 11. Therefore, when the angle between the display screen 11 and the host housing 101 is within the range of 90°≤α≤150°, when the user is using the electronic device 01, the display surface of the display screen 11 can be fully displayed in front of the user, which is convenient for the user to watch. For example, the first preset angle α can be 90°, 100°, 135°, 145°, 150°, etc.

[0097] In this case, when the first preset angle α is within the above range, the display screen 11 can be at a relatively ideal observation angle, and the electronic device 01 can be in a state of being used. At this time, the air duct structure 30, driven by the driving mechanism 40, rotates in the same direction as the display screen 11, and can effectively dissipate the heat of the electronic device 01 during the user's use of the electronic device 01, thereby improving the user's experience.

[0098] In some embodiments of the present application, continue as Figure 8 As shown, in order to ensure that the air duct structure 30, under the drive of the driving mechanism 40, rotates in the same direction as the display screen 11, the shaft 50 does not block the air outlet 301 of the air duct structure 30, when the display screen 11 rotates to a first preset angle α relative to the main body shell 101, the inner wall of the air outlet 301 of the air duct structure 30 can be tangent to the shaft 50, or the inner wall of the air outlet 301 of the air duct structure 30 can be located below the shaft 50.

[0099] Based on this, Fig.9AIn the related technology shown, the heat dissipation port 200 cannot rotate in the same direction as the display screen 11 rotates, so that when the display screen 11 rotates to a certain angle relative to the host housing 101, the shaft 50 will block a portion of the heat dissipation port 200, causing the heat exchanged by the fan 203 to be blocked by a portion of the shaft 50 when flowing through the heat dissipation port 200 and return (solid arrow portion) to the inside of the host housing 101, resulting in heat reflux phenomenon, thereby reducing the heat dissipation efficiency of the electronic device 01.

[0100] also, Fig. 9B In the related art shown, a guide structure 205 is provided for guiding the flow direction of the heat exchanged by the fan 203. Since the guide direction of the guide structure 205 is fixed, when the display screen 11 is rotated to a fixed angle so that the guide direction of the wire structure 205 is tangent to the shaft 50, the heat exchanged by the fan 203 is not blocked at the heat dissipation port 200. However, when the display screen 11 is not rotated to the above-mentioned fixed angle, the shaft 50 will still block the heat dissipation port 200, so that the heat exchanged by the fan 203 will be blocked by a part of the shaft 50 when flowing through the heat dissipation port 200 and return (the solid arrow part) to the inside of the host housing 101, resulting in heat reflux phenomenon, which reduces the heat dissipation efficiency of the electronic device 01.

[0101] Therefore, relative to Fig.9A and Fig. 9B For the scheme shown, the embodiments of the present application provide Figure 8 In the scheme shown, when the display screen 11 rotates to a first preset angle α relative to the main body shell 101, the air duct structure 30 can be driven by the driving mechanism 40 to rotate in the same direction as the display screen 11, so that when the user uses the electronic device, the shaft 50 can reduce or even avoid blocking the air outlet 301 of the air duct structure 30, thereby effectively reducing the probability of heat reflux and improving the heat dissipation efficiency of the electronic device.

[0102] also, Fig.10 In the related art shown, the display screen 11 and the rotating shaft 50 need to be arranged above the host 10 to avoid blocking the heat dissipation port 200. Although this can effectively allow the heat exchanged by the fan 203 to flow out of the heat dissipation port 200, it will increase the thickness of the entire electronic device in the Z direction, which is not conducive to the design of ultra-thin products. Figure 8 In the illustrated solution, the rotating shaft 50 does not need to be stacked on the main body housing 101, thereby being able to effectively reduce the overall thickness of the electronic device.

[0103] in addition, Fig.11In the related art shown in the figure, in order to make the rotating shaft 50 avoid the heat dissipation port 200, the display screen 11 and the host 10 are configured in a special shape, which will reduce the integrity of the product appearance. Figure 8 In the solution shown, the obstruction of the air outlet 301 of the air duct structure 30 by the rotating shaft 50 can be reduced or even avoided, so that the display screen 11 and the host 10 do not need to be configured in a special shape, thereby improving the integrity of the product appearance.

[0104] As can be seen from the above, when the display screen 11 rotates to the first preset angle α relative to the host housing 101, Figure 8 The driving mechanism 40 shown can convert the rotational motion of the display screen 11 into the linear motion of the driving mechanism 40 itself. In addition, the driving mechanism 40 can also convert the linear motion into the rotational motion of the air duct structure 30, so that under the drive of the driving mechanism 40, the air duct structure 30 can rotate in the same direction as the display screen 11, thereby reducing the shielding of the display screen 11 by the rotating shaft 50. The structure of the driving mechanism 40 and the structure related to the driving mechanism 40 in the electronic device are described below by way of example.

[0105] From the above, we can see that if Fig.12 As shown, in order to enable the display screen 11 and the host housing 101 to be rotatably connected, the electronic device 01 may include a rotating shaft 50. In some embodiments of the present application, the rotating shaft 50 may include a pin 501 and a shaft housing 502. The shaft housing 502 may be connected to the display screen 11, and a shaft hole 503 is provided on the shaft housing 502. For example, when the display screen 11 includes a top cover 111 and a front frame 112, the shaft housing 502 may be connected to at least one of the top cover 111 and the front frame 112 as an integrated structure.

[0106] On this basis, continue Fig.12 As shown, the pin 501 can be arranged in the accommodating cavity 1013 of the main body shell 101, and the first end a1 of the pin 501 can be directly and indirectly connected to the main body shell 101, so that the pin 501 can rotate around the X axis. In addition, the second end a2 of the pin 501 can be installed in the shaft hole 503 of the shaft shell 502, so that the second end a2 of the pin 501 can be connected to the display screen 11, and then the positions of the pin 501 and the display screen 11 can be relatively fixed. For example, the second end a2 of the pin 501 can be interference fit, snap-fit, threaded or bonded with the shaft hole 503 of the shaft shell 502. In this way, the display screen 11 is connected to the second end a2 of the pin 501 through the shaft shell 502, so that the positions of the display screen 11 and the pin 501 are relatively fixed. In addition, the first end a1 of the pin 501 is connected to the main body shell 101, so that the display screen 11 can be indirectly connected to the main body shell 101 through the above-mentioned rotating shaft 50.

[0107] Based on this, Fig.12 The drive mechanism 40 shown may include: Fig.13A The linear transmission part 400, the first transmission part 401 and the second transmission part 402 are shown. The linear transmission part 400 can be connected to the linear transmission part 400 along the Y direction. Fig.12 The main body housing 101 shown in FIG. 1 is slidably matched. The first transmission part 401 can be arranged on the linear transmission part 400. The first transmission part 401 is in transmission connection with the pin shaft 501, so that the first transmission part 401 can rotate the pin shaft 501 around the X axis (such as Fig.12 The rotational motion of the linear transmission part 400 is converted into the linear motion of the linear transmission part 400 along the Y axis. In addition, the second transmission part 402 is arranged on the linear transmission part 400, and the second transmission part 402 is connected to the air duct structure 30 in a transmission manner, so that the second transmission part 402 can convert the linear motion of the linear transmission part 400 along the Y axis into the linear motion of the air duct structure 30 around the X axis (as shown in FIG. Fig.12 The rotational movement shown).

[0108] In this way, continue as Fig.13A As shown, when the display screen 11 rotates around the X axis (such as Fig.12 When the display screen 11 rotates around the X-axis (as shown in FIG. 1 ), the first transmission part 401 converts the rotational motion of the display screen 11 around the X-axis into the linear motion of the linear transmission part 400 along the Y-axis, and the second transmission part 402 can convert the linear motion of the linear transmission part 400 along the Y-axis into the linear motion of the air duct structure 30 around the X-axis (as shown in FIG. Fig.12 The air duct structure 30 can rotate in the same direction as the display screen 11 by means of the rotational movement of the air duct structure 30 (as shown).

[0109] The structures of the linear transmission part 400, the first transmission part 401 and the second transmission part 402 in the driving mechanism 40 are described in detail below. Fig.13A The linear transmission unit 400 may include Fig. 13B The rack 410 shown has an extending direction that is the same as the sliding direction (ie, the Y direction) of the linear transmission part 400 . Fig.13A The first transmission part 401 may include Fig. 13B The first gear 411 shown in the figure can be meshed with one end of the rack 410 facing the pin 501 and connected to the pin 501. In addition, Fig.13A The second transmission part 402 may include Fig. 13B The second gear 412 shown can be meshed with the end of the rack 410 away from the pin 501. The second gear 412 can also be connected to the air duct structure 30.

[0110] In this way, the clockwise rotation of the pin shaft 501 can drive the first gear 411 to rotate, and then the first gear 411 can drive the rack 410 to slide toward the pin shaft 501 along the Y direction, thereby driving the second gear 412 to rotate clockwise. Since the second gear 412 is connected to the air duct structure 30, and the air duct structure 30 is rotatably connected to the host housing 101, the rack 410 can drive the air duct structure 30 to rotate clockwise through the second gear 412.

[0111] Or, in other embodiments of the present application, Fig.13A The linear transmission unit 400 may include Fig. 13C The transmission rod 4001 shown in the figure has an extension direction which is the same as the sliding direction (ie, the Y direction) of the linear transmission part 400 . Fig.13A The first transmission part 401 may include Fig. 13C The transmission groove 4011 shown in the figure may be opened at one end of the transmission rod 4001 facing the pin 501 , and the opening of the transmission groove 4011 faces the pin 501 .

[0112] also, Fig.13A The second transmission part 402 may include Fig. 13C The first guide groove 4021 shown is provided at one end of the transmission rod 4001 away from the pin 501, and the guiding direction (i.e., Z direction) of the first guide groove 4021 is perpendicular to the extending direction (i.e., Y direction) of the transmission rod 4001 and the extending direction (i.e., X direction) of the pin 501. The air duct structure 30 can slide with the first guide groove 4021 along the guiding direction (i.e., Z direction).

[0113] Continue as Fig. 13C As shown, the rotating shaft 50 may further include a protrusion 504, which may be located in the accommodating cavity 1013 ( Fig.12 As shown in the figure, the protrusion 504 is arranged on the pin 501 and connected to the pin 501. For example, the protrusion 504 can be made of the same material as the pin 501, so as to be connected as an integrated structural member through a single preparation process (for example, injection molding, etc.). Alternatively, for another example, the protrusion 504 can also be connected to the pin 501 by means of clamping, threading, bonding, etc. During the rotation of the pin 501, the protrusion 504 can be driven to rotate together.

[0114] The above is an example of the structure of the linear transmission part 400, the first transmission part 401 and the second transmission part 402 in the driving mechanism 40, and does not constitute a limitation on the structure of the linear transmission part 400, the first transmission part 401 and the second transmission part 402. As long as the first transmission part 401 can convert the rotational motion of the display screen 11 around the X-axis into the linear motion of the linear transmission part 400 along the Y-axis, the second transmission part 402 can convert the linear motion of the linear transmission part 400 along the Y-axis into the linear motion of the air duct structure 30 around the X-axis (such as Fig.12 The rotational motion of the embodiment (as shown) belongs to the protection scope of this application.

[0115] For the convenience of explanation, the following are based on Fig.13A The linear transmission unit 400 includes Fig. 13C The transmission rod 4001 shown, Fig.13A The first transmission part 401 includes Fig. 13C The transmission groove 4011 shown, Fig.13A The second transmission part 402 may include Fig. 13C The first guide groove 4021 shown is used as an example for explanation.

[0116] Based on this, in some embodiments of the present application, when Fig.14A As shown, when the display screen 11 is closed on the host housing 101, the pin 501 can be in a static state. Fig. 14B As shown, the protrusion 504 can be located outside the transmission groove 4011, and there is no transmission connection between the protrusion 504 and the transmission groove 4011, that is, the display screen 11 (such as Fig.14A There is no transmission connection between the air duct structure 30 and the driving mechanism 40. Therefore, the driving mechanism 40 will not slide along the Y axis. In this case, the air duct structure 30 will not slide relative to the first guide groove 4021 of the driving mechanism 40, and the air duct structure 30 will not rotate with the rotation of the display screen 11. In this case, continue as Fig.14A As shown, the air outlet direction of the air outlet 301 of the air duct structure 30 can be parallel to the plate surface of the upper cover plate 1011, that is, the Y direction.

[0117] Or, in other embodiments of the present application, Fig.15A or Fig. 15B As shown, the pin 501 can rotate clockwise to rotate the display screen 11 to a second preset angle β relative to the host housing 101, and β<α. For example, it can be seen from the above that the range of the first preset angle α can be 90°≤α≤150°. Since β<α, the range of the second preset angle β can be 0°≤β≤90°. When the display screen 11 is rotated to an angle range of 0°≤β≤90° relative to the host housing 101, the angle between the display screen 11 and the host housing 101 is small. Fig.15AThe rotating shaft 50 shown will not substantially block the air outlet 301 of the air duct structure 30. Fig.15A Take β<90° as an example. Fig. 15B The description is made by taking β=90° as an example.

[0118] Based on this, Fig. 15C (along Fig.14A As shown in the view taken along the A1 direction in FIG. 1 , when the pin 501 drives the protrusion 504 to rotate clockwise, the protrusion 504 can rotate from the outside of the transmission groove 4011 to the inside of the transmission groove 4011 and slide with the transmission groove 4011. However, since β<α, the protrusion 504 will not abut against the groove wall 4012 of the transmission groove 4011 away from the transmission rod 4001.

[0119] At this time, the movement of the protrusion 504 will not change the movement of the driving mechanism 40, so there is no transmission connection between the protrusion 504 and the transmission groove 4011, that is, Fig.15A or Fig. 15B There is no transmission connection between the display screen 11 and the driving mechanism 40. The driving mechanism 40 will not slide along the Y axis. In this case, the air duct structure 30 will not slide relative to the first guide groove 4021 of the driving mechanism 40, and the air duct structure 30 will not rotate with the rotation of the display screen 11. Fig.15A or Fig. 15B As shown, the air outlet direction of the air outlet 301 of the air duct structure 30 can be parallel to the plate surface of the upper cover plate 1011, that is, the Y direction.

[0120] Based on this, in order to ensure that the rotating shaft 50 does not block the air outlet 301 of the air duct structure 30 when the display screen 11 is closed on the host housing 101 or the display screen 11 is rotated to the second preset angle β relative to the host housing 101, as shown in FIG. Fig.15D As shown, the vertical projection of the pin 501 and the entire rotating shaft 50 on the tilted portion 10122 of the lower cover 1012 does not overlap with the position of the mounting hole 100 opened on the tilted portion 10122. In addition, the vertical projection of the pin 501 and the entire rotating shaft 50 on the tilted portion 10122 is arranged close to the upper cover 1011 relative to the position of the mounting hole 100.

[0121] In this way, when the display screen 11 is closed on the main housing 101, or the display screen 11 is rotated at a smaller angle relative to the main housing 101, such as the second preset angle β mentioned above, the air duct structure 30 does not need to rotate with the display screen 11, and the rotating shaft 50 will not block the air outlet 301 of the air duct structure 30.

[0122] Alternatively, in some other embodiments of the present application, when the display screen 11 rotates relative to the host housing 101 from the second preset angle β to Fig.16A When the first preset angle α is shown, Fig. 16B As shown, the pin 501 can drive the protrusion 504 located in the transmission groove 4011 in the clockwise direction to move the groove wall 4012 (as shown in FIG. Fig. 16C as shown) abutment.

[0123] At this time, if Fig. 16C (along Fig. 16B As shown in the view taken along the A2 direction in FIG. 1 , since the protrusion 504 abuts against the groove wall 4012 of the transmission groove 4011 on the side away from the transmission rod 4001, the display screen 11 can be transmission-connected with the driving mechanism 40 through the protrusion 504. Therefore, when the pin 501 drives the protrusion 504 to continue rotating, the protrusion 504 can drive the linear transmission part 400 to slide toward the pin 501 (to the right) along the Y direction.

[0124] In this case, continue as Fig. 16C As shown, the first guide groove 4021 provided on the linear transmission part 400 will also slide along the Y direction toward the pin shaft 501 (to the right), so that the driving mechanism 40 is in transmission connection with the air duct structure 30, so that the air duct structure 30 can slide upward in the first guide groove 4021, and also slide along the Y direction toward the pin shaft 501 (to the right) following the first guide groove 4021, so that the air duct structure 30 rotates clockwise to achieve the purpose of rotating in the same direction as the display screen 11. Fig. 16C The dotted lines in FIG. 3 are used to indicate the positions of the driving mechanism 40 and the air duct structure 30 when the driving mechanism 40 and the air duct structure 30 are not in transmission connection.

[0125] In summary, by providing the protrusion 504 on the pin shaft 501, the drive mechanism 40 and the display screen 11, as well as the drive mechanism 40 and the air duct structure 30 can be intermittently connected. Fig.14A As shown, when the display screen 11 is closed on the host housing 101, or as Fig.15A As shown, when the display screen 11 rotates to the second preset angle β relative to the host housing 101, and β<α, the driving mechanism 40 and the display screen 11 are in a state of no transmission connection, and the driving mechanism 40 and the air duct structure 30 are in a state of no transmission connection. At this time, since the second preset angle β is small, for example, less than or equal to 90°, the angle between the display screen 11 and the host housing 101 is small, Fig.15A The probability of the rotating shaft 50 blocking the air outlet 301 of the air duct structure 30 is small, so the air duct structure 30 does not need to rotate with the display screen 11.

[0126] In addition, when the display screen 11 is rotated relative to the host housing 101 from the second preset angle β to Fig.16A At the first preset angle α shown, the angle between the display screen 11 and the main body housing 101 is relatively large, and the driving mechanism 40 and the display screen 11, as well as the driving mechanism 40 and the air duct structure 30 are all in a state of transmission connection. In this way, the display screen 11 can drive the driving mechanism 40 to move linearly along the Y axis during rotation, and then the driving mechanism 40 drives the air duct structure 30 to rotate in the same direction as the display screen 11, so that the air outlet 301 of the air duct structure 30 faces away from the upper cover plate 1011, thereby avoiding being blocked by the rotating shaft 50.

[0127] As can be seen from the above, when the driving mechanism 40 drives the air duct structure 30 to rotate, it needs to slide along the Y-axis toward the display screen 11. Based on this, by setting an intermittent transmission connection between the driving mechanism 40 and the display screen 11, and between the driving mechanism 40 and the air duct structure 30, it is not necessary to drive the air duct structure 30 to rotate together with the driving mechanism 40 when the display screen 11 starts to rotate, thereby reducing the sliding stroke of the driving mechanism 40, which is conducive to increasing the component space inside the host housing 101.

[0128] On this basis, in some embodiments of the present application, when the display screen 11 rotates from the first preset angle α to the third preset angle γ relative to the host housing 101, where γ>α, the display screen 11 can be in a state of maximum opening angle, in which case, the air duct structure 30 does not need to be further rotated. In this case, a limit structure can be provided in the above-mentioned driving mechanism 40, and the limit structure is described by example below.

[0129] For example, Fig.17 As shown, the bottom of the transmission groove 4011 of the driving mechanism 40 is a first arc surface S1, and the curvature of the first arc surface S1 can be the same as the curvature of the surface of the pin shaft 501. The transmission groove 4011 runs through the transmission rod 4001 on the side away from the pin shaft 501 (i.e., the lower side in the figure), so that when the pin shaft 501 drives the protrusion 504 to rotate, it can slide into the transmission groove 4011 from the lower side of the transmission groove 4011, thereby slidingly cooperating with the transmission groove 4011.

[0130] In addition, continue to Fig.17 As shown, a limiting groove 4013 is provided at one end of the transmission rod 4001 facing the pin shaft 501, and the opening of the limiting groove 4013 faces the pin shaft 501. At least a portion of the groove bottom of the limiting groove 4013 is a second arc surface S2, and the second arc surface S2 has the same curvature as the surface of the pin shaft 501, and the second arc surface S2 and the first arc surface S1 can be concentrically arranged.

[0131] On this basis, the depth (dimension along the Z direction) of the limiting groove 4013 can be smaller than the depth (dimension along the Z direction) of the transmission groove 4011. Based on this, if the display screen 11 rotates to the third preset angle γ relative to the host housing 101, the pin 501 can abut against the second arc surface S2, thereby preventing the transmission rod 4001 from further moving toward the pin 501 along the Y direction. Since the second arc surface S2 and the pin 501 have the same surface curvature, the contact area between the second arc surface S2 and the pin 501 can be increased, effectively ensuring the limiting effect of the limiting groove 4013 on the transmission rod 4001.

[0132] In this way, when the display screen 11 is at the maximum viewing opening angle (i.e., the third preset angle γ), the second arc surface S2 of the limiting groove 4013 abuts against the pin shaft 501, so that the driving mechanism 40 will not continue to move along the Y direction relative to the main body housing 101, thereby preventing the driving mechanism 40 from further driving the air duct structure 30 to rotate, thereby playing a role in limiting the air duct structure 30.

[0133] For example, the range of the third preset angle γ is: 130°≤γ≤155°. When the angle between the display screen 11 and the host housing 101 is less than 130°, the display screen 11 is still within the range of the user's optimal viewing angle. When the angle between the display screen 11 and the host housing 101 is greater than 155°, the opening angle of the display screen 11 is too large, and the damping structure connected to the rotating shaft 50 will be affected under the weight of the display screen 11 itself. Therefore, the maximum viewing opening angle of the display screen 11 can be limited to the range of 130°≤γ≤155°.

[0134] In addition, if Fig. 16C As shown, when the driving mechanism 40 moves rightward along the Y axis, the air duct structure 30 that is slidably matched with the first guide groove 4021 of the driving mechanism 40 can slide upward in the first guide groove 4021, and also slide along the Y direction toward the pin 501 (to the right) following the first guide groove 4021, so that the air duct structure 30 rotates clockwise. In order to enable the air duct structure 30 to slide with the first guide groove 4021, in some embodiments of the present application, such as Fig.18A As shown, the electronic device 01 may further include a first connecting member 61 .

[0135] Among them, continue as Fig.18A As shown, the first connecting member 61 may be located between the transmission rod 4001 and the air duct structure 30, and the first connecting member 61 may be connected to the air duct structure 30. Fig.18B As shown, a portion of the first connecting member 61 is located in the first guide groove 4021 and slides with the first guide groove 4021. The first connecting member 61 is also rotated with the main housing 101 (as shown in FIG. Fig.16A In this way, since the first connecting member 61 is connected to the air duct structure 30 and is rotatably connected to the host housing 101, the air duct structure 30 can be indirectly rotatably connected to the host housing 101 through the first connecting member 61. In addition, the first connecting member 61 is also slidably matched with the first guide groove 4021, so the air duct structure 30 can be indirectly slidably matched with the first guide groove 4021 through the first connecting member 61.

[0136] For example, Fig.18A As shown, the first connecting member 61 may include a first sliding rod 611 and a first rotating rod 612. The first end (e.g., the left end) of the first sliding rod 611 is located in the first guide groove 4021, and the first end (e.g., the left end) of the first sliding rod 611 can be slidably matched with the first guide groove 4021, so that the first sliding rod 611 can slide along the guide direction (e.g., the Z direction) of the first guide groove 4021. In addition, the first end (e.g., the left end) of the first rotating rod 612 can be aligned with the main housing 101 (e.g., the left end) of the main housing 101. Fig.16A In order to connect the first connecting member 61 to the air duct structure 30, for example, the second end (for example, the right end) of the first sliding rod 611 and the second end (for example, the right end) of the first rotating rod 612 are both connected to the air duct structure 30.

[0137] Or, for example, Fig.18A As shown, the first connecting member 61 may further include a first connecting plate 613, which may be disposed between the first sliding rod 611 and the first rotating rod 612, and the first connecting plate 613 is connected to the first sliding rod 611 and the first rotating rod 612. In this way, the rigidity of the entire first connecting member 61 may be improved by the first connecting plate 613. Based on this, in order to connect the first connecting member 61 to the air duct structure 30, at least one of the second end (e.g., the right end) of the first sliding rod 611 and the second end (e.g., the right end) of the first rotating rod 612 may be connected to the air duct structure 30.

[0138] Alternatively, in order to avoid other components when the first connecting member 61 drives the duct structure 30 to slide along the first guide groove 4021, the second end (for example, the right end) of the first rotating rod 612 located below the first sliding rod 611 can be connected to the duct structure 30.

[0139] In this case, if Fig.18B As shown, the air duct structure 30 can be slidably matched with the first guide groove 4021 through the first sliding rod 611, so that the first sliding rod 611 drives the air duct structure 30 to slide along the guide direction (for example, the Z direction) of the first guide groove 4021. In addition, the air duct structure 30 can be slidably matched with the main body housing 101 (for example, the Z direction) through the first rotating rod 612. Fig.16A As shown in the figure, the air duct structure 30 and the display screen 11 are rotatably connected so that the air duct structure 30 and the display screen 11 can rotate in the same direction under the drive of the driving mechanism 40.

[0140] Based on this, when the display screen 11 rotates relative to the host housing 101 from the second preset angle β to Fig.18C At the first preset angle α shown, the first sliding rod 611 slidably matched with the first guide groove 4021 can drive the air duct structure 30 to slide in the first guide groove 4021 in the direction from the lower cover body 10121 to the upper cover 1011 (i.e. upward along the Z direction). At the same time, the first rotating rod 612 drives the air duct structure 30 to rotate relative to the host housing 101, so that the entire first connecting member 61 can drive the air duct structure 30 and the display screen 11 to rotate clockwise in the same direction, so that the air outlet direction of the air outlet 301 of the air duct structure 30 can be away from the upper cover 1011, so as to avoid the rotating shaft 50 blocking the air outlet 301.

[0141] As can be seen from the above, the first connecting member 61 can realize the sliding fit between one end of the air duct structure 30 and the first guide groove 4021 and the rotation connection with the host housing 101. Based on this, in order to keep both ends of the air duct structure 30 stable during the rotation process, as shown in FIG. Fig.18A As shown, the electronic device may further include a guide member 62 and a second connecting member 63 .

[0142] The guide member 62 can be disposed at one end of the air duct structure 30 facing away from the linear transmission portion (i.e., the transmission rod 4001), and the guide member 62 can be connected to the host housing 101 so that the guide member 62 will not be relative to the host housing 101 (e.g., Fig.16A The guide member 62 is provided with a third guide groove 621, and the guiding direction of the third guide groove 621 is the same as the rotation direction of the air duct structure 30. In addition, the second connecting member 63 can be located between the guide member 62 and the air duct structure 30, the second connecting member 63 is connected to the air duct structure 30, and a part of the second connecting member 63 is located in the third guide groove 621 and slidably cooperates with the third guide groove 621. In addition, the second connecting member 63 is rotatably connected to the guide member 62. Since the guide member 62 is connected to the host housing 101, the second connecting member 63 can be rotatably connected to the host housing 101 through the guide member 62.

[0143] In this way, continue by Fig.18AAs shown, since the second connecting member 63 is connected to the air duct structure 30 and is rotatably connected to the host housing 101 through the guide member 62, the air duct structure 30 can be indirectly rotatably connected to the host housing 101 through the second connecting member 63 and the guide member 62. In addition, the second connecting member 63 is also slidably matched with the third guide groove 621, so the air duct structure 30 can be indirectly slidably matched with the third guide groove 621 through the second connecting member 63.

[0144] In this case, when one end of the air duct structure 30 close to the transmission rod 4001 slides upward in the first guide groove 4021, it slides along the Y direction toward the pin shaft 501 (to the right) following the first guide groove 4021, so that the air duct structure 30 rotates clockwise, the end of the air duct structure 30 close to the guide member 62 can slide along the third guide groove 621, so that the two ends of the air duct structure 30 can remain stable during the rotation of the air duct structure 30.

[0145] For example, Fig.18D As shown, the second connecting member 63 may include a second sliding rod 631 and a second rotating rod 632. The first end (right end) of the second sliding rod 631 is located in the third guide groove 621, and the first end (right end) of the second sliding rod 631 is slidably matched with the third guide groove 621. The first end (right end) of the second rotating rod 632 can extend into the guide member 62 and be rotatably connected to the guide member 62. In order to connect the second connecting member 63 to the air duct structure 30, for example, the second end (for example, the left end) of the second sliding rod 631 and the second end (for example, the left end) of the second rotating rod 632 are both connected to the air duct structure 30.

[0146] Or, for example, Fig.18D As shown, the second connecting member 63 may include a third connecting plate 633, which may be disposed between the second sliding rod 631 and the second rotating rod 632, and the third connecting plate 633 may be connected to the second sliding rod 631 and the second rotating rod 632. In this way, the rigidity of the entire second connecting member 63 may be improved by the third connecting plate 633. Based on this, in order to connect the second connecting member 63 to the air duct structure 30, at least one of the second end (e.g., the left end) of the second sliding rod 631 and the second end (e.g., the left end) of the second rotating rod 632 may be connected to the air duct structure 30. Alternatively, when the air duct structure 30 is connected to the air duct structure 30, as shown in FIG. Fig.18B When the second end (eg, the right end) of the first rotating rod 612 is connected to the second end (eg, the right end) of the first rotating rod 612, in order to make the two ends of the air duct structure 30 flush, the air duct structure 30 is connected to the second end (eg, the right end) of the first rotating rod 612. Fig.18D The second end (eg, left end) of the second rotation rod 632 is shown connected.

[0147] As can be seen from the above, when the driving mechanism 40 is in transmission connection with the display screen 11, the display screen 11 can be driven to rotate along the driving mechanism 40. Fig.19 In the Y direction shown, the drive mechanism 40 slides relative to the host housing 101 toward the pin 501. The following is an example of a structure in the electronic device 01 that enables the drive mechanism 40 to slide relative to the host housing 101.

[0148] In some embodiments of the present application, the electronic device 01 may further include: Fig.19 The pin connecting member 70 and the rotating bearing frame 71 are shown. The pin connecting member 70 is located in the accommodating cavity 1013 (such as Figure 4A The pin connection member 70 is provided with a connection hole (not shown in the figure), and the first end of the pin 501 is located in the connection hole and is rotatably connected to the pin connection member 70. For example, the electronic device 01 may further include a damping component disposed in the connection hole of the pin connection member 70, and the damping component may support the display screen 11 during the rotation of the display screen 11 relative to the host housing, so that the display screen 11 can remain in the open state at any angle when it is rotated to the angle.

[0149] In addition, the rotating bearing frame 71 is located in the accommodating cavity 1013 (such as Figure 4A 4 ) is connected with the pin connection member 70, and the swivel bearing frame 71 is slidably matched with the linear transmission part 400 of the driving mechanism 40. For example, at least one of the pin connection member 70 and the swivel bearing frame 71 can be connected to the main body housing 101. In this way, since the pin connection member 70 and the swivel bearing frame 71 are connected to each other, the pin connection member 70 and the swivel bearing frame 71 can be connected to the main body housing 101.

[0150] In this case, since the pin connection member 70 is rotatably connected to the pin 501, the display screen 11 can be indirectly rotatably connected to the host housing 101 through the pin 501 and the pin connection member 70. In addition, the swivel bearing bracket 71 is slidably matched with the linear transmission part 400 of the driving mechanism 40, so the linear transmission part 400 of the driving mechanism 40 can be indirectly slidably matched with the host housing 101 through the swivel bearing bracket 71.

[0151] On this basis, continue Fig.19As shown, the electronic device 01 further includes a guide post 72, which can be arranged on the rotating bearing frame 71, and the guide post 72 can be connected to the rotating bearing frame 71. Based on this, the driving mechanism 40 can also include a second connecting plate 403. The second connecting plate 403 can be arranged on the rotating bearing frame 71, and the second connecting plate 403 is connected to the linear transmission part 400. In addition, a second guide groove 4031 is provided on the second connecting plate 403, and the guiding direction of the second guide groove 4031 is the same as the sliding direction (i.e., the Y direction) of the linear transmission part 400. Based on this, the guide post 72 can be arranged in the second guide groove 4031, and the guide post 72 can be slidably matched with the second guide groove 4031.

[0152] In this way, by setting a guide column 72 on the rotating bearing frame 71 and setting a second connecting plate 403 connected to the linear transmission part 400 on the linear transmission part 400, the guide column 72 can slide in the second guide groove 4031 opened on the second connecting plate 403 during the movement of the linear transmission part 400 along the Y direction, so that the sliding direction of the linear transmission part 400 is consistent with the guiding direction of the second guide groove 4031 (i.e., the Y direction).

[0153] The above description is based on the example of setting the guide column 72 on the rotating bearing frame 71 and opening the second guide groove 4031 on the second connecting plate 403 connected to the linear transmission part 400. In other embodiments of the present application, the guide column 72 can also be connected to the linear transmission part 400, and the second connecting plate 403 provided with the second guide groove 4031 can be connected to the rotating bearing frame 71.

[0154] The above is an explanation of the example of the display screen 11 rotating clockwise relative to the host housing 101, with the angle increasing in sequence to open the display screen 11, for example, rotating from the second preset angle β to the first preset angle α and the third preset angle γ. In other embodiments of the present application, when the user rotates the opened display screen 11 counterclockwise relative to the host housing 101, with the angle decreasing in sequence to close the display screen 11, when the display screen 11 rotates to the second preset angle β (0°≤β≤90°), it can be seen from the above that, Fig.19 As shown, the protrusion 504 on the pin 501 no longer abuts against the groove wall of the driving mechanism 40 that serves as the transmission groove 4011, or rotates out of the transmission groove 4011. At this time, the driving mechanism 40 can be reset to make the driving mechanism 40 slide away from the pin 501 along the Y direction, thereby driving the air duct structure 30 to rotate counterclockwise, so as to align the air outlet direction of the air outlet 301 of the air duct structure 30 with the upper cover plate 1011 (as shown in FIG. Fig.18C shown) in parallel.

[0155] In some embodiments of the present application, in order to reset the driving mechanism 40, the electronic device 01 may further include: Fig.19 The elastic member 73 shown in the figure. For example, the elastic member 73 can be an elastic rubber strip or a spring, etc. For the convenience of description, the following description is made by taking the elastic member 73 as a spring as an example.

[0156] Continue as Fig.19 As shown, the first end (e.g., the right end) of the elastic member 73 is connected to the end of the linear transmission part 400 of the driving mechanism 40 away from the pin 501, and the second end (e.g., the left end) of the elastic member 73 is connected to the main body housing 101 (e.g., Fig.18C For example, when the electronic device further includes a rotating bearing frame 71, the second end (for example, the left end) of the elastic member 73 can be connected to the rotating bearing frame 71, so that the second end of the elastic member 73 can be indirectly connected to the host housing 101 (for example, the left end) through the rotating bearing frame 71. Fig.18C shown) are connected.

[0157] In this case, when the angle between the display screen 11 and the host housing 101 is the first preset angle α (90°≤α≤150°), Fig. 20A As shown, the pin shaft 501 rotates clockwise, and the protrusion 504 abuts against the groove wall of the transmission groove 4011. At this time, the driving mechanism 40 is in transmission connection with the protrusion 504, so that the driving mechanism 40 slides toward the pin shaft 501 along the Y direction to drive the air duct structure 30 to rotate clockwise. At this time, the elastic member 73 is in a stretched state.

[0158] In addition, when the angle between the display screen 11 and the host housing 101 is the second preset angle β (0°≤β≤90°), as shown in FIG. Fig. 20B As shown, the pin shaft 501 rotates counterclockwise, and the protrusion 504 no longer abuts against the groove wall of the transmission groove 4011. At this time, the driving mechanism 40 is not in transmission connection with the protrusion 504, and the elastic force of the elastic member 73 causes the driving mechanism 40 to slide away from the pin shaft 501 along the Y direction, so as to drive the air duct structure 30 to rotate counterclockwise and reset.

[0159] On this basis, in order to avoid interference between the rotating bearing frame 71 and the elastic member 73 when the elastic member 73 stretches and contracts, as shown in FIG. Fig.21 As shown, the swivel bearing frame 71 may be provided with an avoidance groove 711 , and the vertical projection of the elastic member 73 on the plate surface of the swivel bearing frame 71 overlaps with the avoidance groove 711 .

[0160] The above description is based on an example in which the electronic device 01 includes a duct structure 30 and a driving mechanism 40 driving the duct structure 30. In other embodiments of the present application, Fig. 22 As shown, the electronic device 01 may include two air duct structures, namely a first air duct structure 30a and a second air duct structure 30b, and two driving mechanisms, namely a first driving mechanism 40a and a second driving mechanism 40b.

[0161] The first driving mechanism 40a is used to drive the first air duct structure 30a to rotate, and the first driving mechanism 40a and the first air duct structure 30a can be arranged on the left side of the host housing 101. The second driving mechanism 40b is used to drive the second air duct structure 30b to rotate, and the second driving mechanism 40b and the second air duct structure 30b can be arranged on the right side of the host housing 101. The above-mentioned first air duct structure 30a and the second air duct structure 30b, and the arrangement of the first driving mechanism 40a and the second driving mechanism 40b are the same as described above, and will not be repeated here.

[0162] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application shall be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
