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 developing in the direction of multi-function and high speed. The integration of some electronic components in electronic devices, such as system on chip (SOC), central processing unit (CPU), graphics processing unit (GPU), memory 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. However, electronic devices also need to meet the requirements of lightweight design, which will result in the heat generated inside the electronic device cannot be effectively dissipated, reducing the heat dissipation efficiency and affecting the product performance. Summary of the invention

[0003] The present application provides an electronic device for alleviating the problem of low heat dissipation efficiency of the electronic device.

[0004] In order to achieve the above purpose, this application adopts the following technical solutions:

[0005] In one aspect of the present application, an electronic device is provided, which includes a display screen, a host housing, and a drive assembly. The host housing may include an upper cover plate and a lower cover plate connected to each other, a receiving chamber is formed between the upper cover plate and the lower cover plate, and the host housing is rotatably connected to the display screen. The drive assembly is arranged in the receiving chamber. The drive assembly includes a rotating mechanism and a sliding mechanism. The rotating mechanism is connected to the display screen. The sliding mechanism is transmission-connected to the rotating mechanism, and the sliding mechanism is slidably matched with at least a portion of the lower cover plate. The rotating mechanism is used to drive the sliding mechanism to move in a direction away from or toward the rotation center of the display screen under the rotation of the display screen; the sliding mechanism is used to drive at least a portion of the lower cover plate to move in a direction away from or toward the upper cover plate. In summary, the display screen is connected to the rotating mechanism, so that the angle between the display screen and the host housing gradually increases during the process of the display screen rotating from a closed state to an open state. The display screen can drive the rotating mechanism to rotate. The rotating mechanism is transmission-connected to the sliding mechanism, so that during the rotation of the rotating mechanism, the sliding mechanism can drive the sliding mechanism to move toward or away from the rotation center of the display screen. The sliding mechanism is slidably matched with at least a portion of the lower cover plate, so that when the sliding mechanism moves in a direction toward or away from the rotation center of the display screen, at least a portion of the lower cover plate can be driven to move away from the upper cover plate. In this case, the distance between the upper cover plate and the lower cover plate can be increased. Based on this, when the above electronic device adopts an air-cooling heat dissipation method, the air circulation rate in the accommodating cavity can be increased to improve the heat dissipation efficiency.

[0006] In an optional embodiment, the electronic device further comprises a rotating shaft, which is connected to the display screen, and the rotating shaft is rotatably connected to the host housing. In addition, the rotating mechanism comprises a first gear and a second gear. The first gear is arranged on the rotating shaft, and the first gear is connected to the rotating shaft. The second gear meshes with the first gear, and the second gear is transmission-connected to the sliding mechanism. Wherein, the first gear is used to drive the second gear to rotate under the rotation of the display screen, and the second gear is used to drive the sliding mechanism to move in a direction away from or toward the rotating shaft. In this way, the first gear can be a driving wheel, and the second gear can be a driven wheel. Therefore, during the rotation of the first gear, the second gear can be driven to rotate, and the rotation direction of the first gear is opposite to the rotation direction of the second gear. In addition, the second gear is transmission-connected to the sliding mechanism, so that the entire rotating mechanism can be transmission-connected to the sliding mechanism. In this case, the first gear is used to drive the second gear to rotate under the rotation of the display screen, and the second gear can drive the sliding mechanism transmission-connected to the second gear to move in a direction toward or away from the rotation center of the display screen.

[0007] In an optional embodiment, the sliding mechanism includes a pull rod, the extension direction of the pull rod is perpendicular to the rotating shaft, and the pull rod is slidably matched with at least a part of the lower cover plate. A first guide groove is provided at one end of the pull rod facing the rotating shaft, and the extension direction of the first guide groove is perpendicular to the upper cover plate. The driving assembly includes a first guide rod, the first end of the first guide rod is connected to the second gear, and the second end of the first guide rod is located in the first guide groove and slidably matched with the first guide groove. In this way, when the display screen rotates from a closed state to an open state, the display screen can drive the first gear to rotate counterclockwise. At this time, the second gear meshed with the first gear rotates clockwise, thereby driving the first guide rod to slide in the first guide groove. At this time, the pull rod can be pushed away from the rotating shaft to move, and then the movable plate can be driven to move downward. Conversely, when the display screen rotates from an open state to a closed state, the display screen can drive the first gear to rotate clockwise. At this time, the second gear meshed with the first gear rotates counterclockwise, thereby driving the first guide rod to slide in the first guide groove. At this time, the pull rod can be pulled to move toward the rotating shaft, thereby driving the movable plate to move upward.

[0008] In an optional embodiment, the sliding mechanism includes a rack and a pull rod. The first end of the rack is meshed with the second gear. The extension direction of the pull rod is perpendicular to the rotating shaft; one end of the pull rod facing the rotating shaft is connected to the second end of the rack; the pull rod is slidably matched with at least a portion of the lower cover. Based on this, when the display screen changes from a closed state to an open state, it can drive the first gear to rotate counterclockwise and the second gear to rotate clockwise. At this time, the rack meshed with the second gear moves away from the rotating shaft, so that the pull rod connected to the rack moves away from the rotating shaft. Next, the pull rod can move the movable plate downward relative to the fixed plate. Conversely, when the display screen rotates from an open state to a closed state, the display screen can drive the first gear to rotate clockwise and the second gear to rotate counterclockwise. At this time, the rack meshed with the second gear moves toward the rotating shaft, thereby pulling the pull rod to move toward the rotating shaft, driving the movable plate to move upward and flush with the fixed plate.

[0009] In an optional embodiment, the drive assembly further includes a first guide block and a second guide rod. The first guide block is connected to at least a portion of the lower cover plate, and a second guide groove is provided on the first guide block. The extension direction of the second guide groove has a first angle α1 with the lower cover plate. The first end of the second guide rod is connected to the pull rod, and the second end of the second guide rod is located in the second guide groove and slides with the second guide groove. In this way, when the pull rod moves away from or toward the rotating shaft, it can drive the second guide rod connected to the pull rod to slide in the second guide groove. Since the second guide groove is inclined, the pull rod can drive at least a portion of the lower cover plate connected to the first guide block to move up or down.

[0010] In an optional embodiment, along the direction from the lower cover plate to the upper cover plate, the first end of the second guide groove is close to the rotating shaft relative to the second end of the second guide groove. In this way, when the display screen changes from the above-mentioned closed state to the open state. The display screen can drive the first gear to rotate counterclockwise during the rotation process. At this time, the second gear meshing with the first gear rotates clockwise. At this time, the first guide rod connected to the second gear slides in the first guide groove, which can drive the pull rod to move away from the rotating shaft, and the second guide rod connected to the pull rod also moves away from the rotating shaft with the pull rod. Based on this, the second guide rod needs to slide in the second guide groove during the movement. Since the second guide groove is inclined, and the lower end of the second guide groove is close to the rotating mechanism, and the upper end of the second guide groove is far away from the rotating mechanism, the second guide rod can apply a downward force to the first guide block during the movement. In this way, the movable plate connected to the first guide block can move downward relative to the fixed plate.

[0011] In an optional embodiment, the driving assembly further includes a second guide block and a third guide rod. The second guide block is located on the side of the first guide block away from the rotating mechanism, the second guide block is connected to at least a part of the lower cover plate, and a third guide groove is provided on the second guide block. The first end of the third guide rod is connected to the pull rod, and the second end of the third guide rod is located in the third guide groove and slides with the third guide groove. In this way, when the pull rod moves away from or toward the rotating shaft, the third guide rod connected to the pull rod can be driven to slide in the third guide groove. Based on this, by spacing the first guide block and the second guide block that slide with the pull rod in the sliding direction of the pull rod, the stability of the sliding connection between the pull rod and at least a part of the lower cover plate can be increased, and then the swing amplitude of the movable plate can be reduced during the movement of the pull rod. In addition, the extension direction of the third guide groove has a second angle α2 with the lower cover plate. Along the direction from the lower cover plate to the upper cover plate, the first end of the third guide groove is close to the rotating shaft relative to the second end of the third guide groove, so that the third guide groove can be tilted. The effect of the inclined setting of the third guide groove can be obtained in the same way as the effect of the inclined setting of the second guide groove, which will not be described in detail here.

[0012] In an optional embodiment, the first angle α1 is equal to the second angle α2. When the display screen is in a closed state, the first gear and the second gear do not rotate, and the pull rod is in a stationary state. At this time, the free end of the second guide rod connected to the pull rod is located at the lower end of the second guide groove, and the third guide rod connected to the above pull rod is located at the lower end of the third guide groove. When the display screen changes from the above closed state to an open state. During the rotation process, the display screen can drive the first gear to rotate counterclockwise and the second gear to rotate clockwise. The first guide rod connected to the second gear slides in the first guide groove to drive the pull rod to move away from the rotating shaft, and the second guide rod and the third guide rod connected to the pull rod also move to the right with the pull rod. Based on this, during the movement of the second guide rod and the third guide rod, they need to slide in the second guide groove and the third guide groove respectively. Since the second guide groove and the third guide groove are inclined, and the lower ends of the second guide groove and the third guide groove are close to the rotating mechanism, and the upper ends of the second guide groove and the third guide groove are far away from the rotating mechanism, the second guide rod can apply a downward force to the first guide block during the movement to the right. Similarly, when the third guide rod moves to the right, a downward force can be applied to the second guide block. In this way, when the display screen is in an open state, the movable plate connected to the first guide block and the second guide block can be moved downward relative to the fixed plate. At this time, the second guide rod is located at the upper end of the second guide groove. Similarly, the third guide rod is located at the upper end of the third guide groove. Conversely, when the display screen rotates from an open state to a closed state, the display screen can drive the first gear to rotate clockwise, the second gear to rotate counterclockwise, and the first guide rod to move in the first guide groove. At this time, the pull rod can be moved toward the rotating shaft, so that the second guide rod and the third guide rod move toward the rotating shaft, driving the movable plate to move upward. In addition, when the display screen is in a closed state, the second guide rod and the third guide rod are respectively located at the lower ends of the second guide groove and the third guide groove, and the movable plate is flush with the fixed plate.

[0013] In an optional embodiment, the first angle α1 is greater than the second angle α2. When the shaft mechanism drives the pull rod to move and drives the movable plate to move downward, since α1>α2, the movable plate will tilt after moving downward, so that an angle is formed between the end of the movable plate facing the rotating mechanism and the fixed plate. In this way, the air intake can be increased, which is conducive to improving the heat dissipation efficiency.

[0014] In an optional embodiment, the driving assembly further includes a second guide block and a third guide rod. The second guide block is located on the side of the first guide block away from the rotating mechanism, the second guide block is connected to at least a portion of the lower cover plate, and a third guide groove is provided on the second guide block. The first end of the third guide rod is connected to the pull rod, and the second end of the third guide rod is located in the third guide groove and slides with the third guide groove. The extension direction of the third guide groove is parallel to the extension direction of the pull rod. Similarly, when the rotating shaft mechanism drives the pull rod to move and drives the movable plate to move downward, the movable plate will also tilt, so that an angle is formed between the end of the movable plate facing the rotating mechanism and the fixed plate, thereby achieving the purpose of increasing the air intake. In addition, the extension direction of the third guide groove is parallel to the extension direction of the pull rod, so that the free end of the third guide rod is easier to slide in the third guide groove.

[0015] In an optional embodiment, the display screen rotates to drive the first gear to rotate in the same direction as the display screen, and the second gear rotates in the opposite direction to the first gear. Based on this, when the display screen rotates to an open state, the second gear drives the pull rod to move in a direction away from the rotation center of the display screen, and the pull rod drives at least a portion of the lower cover plate to move in a direction away from the upper cover plate. In this case, the spacing between the upper cover plate and the lower cover plate can be increased. Based on this, when the above-mentioned electronic device adopts an air-cooled heat dissipation method, the air circulation rate in the accommodating cavity can be increased to improve the heat dissipation efficiency. In addition, when the display screen rotates to a closed state, the second gear drives the pull rod to move in a direction toward the rotation center of the display screen, and the pull rod drives at least a portion of the lower cover plate to move in a direction toward the upper cover plate, so that at least a portion of the above-mentioned lower cover plate returns to its initial position.

[0016] In an optional embodiment, along the direction from the lower cover plate to the upper cover plate, the first end (e.g., the lower end) of the second guide groove is away from the rotation axis relative to the second end (e.g., the upper end) of the second guide groove. Based on this, when the display screen is rotated to an open state, the second gear drives the pull rod to move in a direction toward the rotation center of the display screen, and the pull rod drives at least a portion of the lower cover plate to move in a direction away from the upper cover plate. In this case, the spacing between the upper cover plate and the lower cover plate can be increased. Based on this, when the above-mentioned electronic device adopts an air-cooled heat dissipation method, the air circulation rate in the accommodating cavity can be increased to improve the heat dissipation efficiency. In addition, when the display screen is rotated to a closed state, the second gear drives the pull rod to move in a direction away from the rotation center of the display screen, and the pull rod drives at least a portion of the lower cover plate to move in a direction toward the upper cover plate, so that at least a portion of the above-mentioned lower cover plate is restored to its initial position.

[0017] In an optional embodiment, the electronic device further includes a fan, and the fan is disposed in the accommodating chamber, and the lower cover plate includes a sliding plate and a fixed plate. The movable plate is slidably matched with the sliding mechanism, and the vertical projection of the fan on the lower cover plate overlaps with the movable plate. The fixed plate is connected to the upper cover plate, and a mounting hole penetrating the fixed plate is provided on the fixed plate, and the movable plate is located in the mounting hole. In this way, as the movable plate moves downward, a second air inlet can be formed between one side of the movable plate and the fixed plate, and a second air outlet can be formed between the other side of the movable plate and the fixed plate. In this case, during operation, the fan can suck cold air from the second air inlet into the accommodating chamber, and then the hot air generated after the heat exchange can be discharged from the second air outlet.

[0018] In an optional embodiment, when the display screen is in a closed state, there is a first gap H1 between the fan and the movable plate. When the display screen is in an open state, there is a first gap H2 between the fan and the movable plate, and H2>H1. In this case, when the display screen is in a closed state, the movable plate can be located in the mounting hole, and there is a first gap H1 between the fan and the movable plate. When the display screen rotates from a closed state to an open state, the angle between the display screen and the host housing gradually increases. Driven by the display screen, the rotating mechanism drives the sliding mechanism to move away from or toward the rotating shaft. The sliding mechanism can drive the movable plate to move downward away from the upper cover plate, so that there is a second gap H2 between the fan and the movable plate. Among them, H2>H1, thereby achieving the purpose of increasing the distance between the fan and the movable plate.

[0019] In an optional embodiment, the electronic device further includes a plurality of foot pads, which are arranged on a side surface of the fixed plate away from the upper cover plate. In this case, by adjusting the height of the foot pads, the fixed plate can be supported so that when the display screen is in a closed state, the movable plate flush with the fixed plate can have a certain distance from the above-mentioned desktop. The height of the distance is approximately equal to the height of the foot pads. In this way, when the display screen is rotated from the closed state to the open state, the movable plate can move downward away from the upper cover plate within the height range supported by the foot pads to form the above-mentioned second air inlet and second air outlet.

[0020] In an optional embodiment, the pull rod is slidably matched with the upper cover plate, wherein the pull rod is used to drive the upper cover plate to move toward or away from the lower cover plate, and the relative movement directions of the upper cover plate and the lower cover plate are opposite. In this way, the distance between the upper cover plate and the lower cover plate can be increased, the air flow rate in the accommodating cavity can be increased, and the heat dissipation efficiency can be improved.

[0021] In an optional embodiment, the driving assembly further includes a third guide block and a fourth guide rod. The third guide block is connected to the upper cover plate, and a fourth guide groove is provided on the third guide block, and a third angle α3 is formed between the extension direction of the fourth guide groove and the upper cover plate. The extension direction of the fourth guide groove intersects with the extension direction of the second guide groove. The fourth guide rod, the first end of the fourth guide rod is connected to the pull rod, and the second end of the fourth guide rod is located in the fourth guide groove and slides with the fourth guide groove. In this way, when the display screen changes from a closed state to an open state, under the drive of the rotating mechanism, when the pull rod moves away from the rotating shaft, the fourth guide rod connected to the pull rod can be driven to slide in the fourth guide groove. Since the fourth guide groove is inclined, the pull rod can push the lower cover plate connected to the first guide block to move downward while pushing the upper cover plate connected to the third guide block to move upward. Conversely, when the display screen rotates from an open state to a closed state, under the drive of the rotating mechanism, when the pull rod pushes the lower cover plate to move upward, the upper cover plate connected to the third guide block can be pushed downward.

[0022] In an optional embodiment, along the direction from the upper cover plate to the lower cover plate, the first end of the fourth guide groove is closer to the rotation axis than the second end of the fourth guide groove. In this way, the inclination direction of the fourth guide groove is opposite to the inclination direction of the second guide groove, so that the pull rod can drive the upper cover plate and the lower cover plate to move in opposite directions.

[0023] In an optional embodiment, the driving assembly further includes a fourth guide block and a fifth guide rod. The fourth guide block is located on the side of the third guide block away from the rotating mechanism. The fourth guide block is connected to the upper cover plate, and a fifth guide groove is provided on the fourth guide block. The first end of the fifth guide rod is connected to the pull rod, and the second end of the fifth guide rod is located in the fifth guide groove and slides with the fifth guide groove. In this way, when the pull rod moves away from or toward the rotating shaft, the fifth guide rod connected to the pull rod can be driven to slide in the fifth guide groove, so that during the movement of the pull rod, the upper cover plate can be stably driven to move up and down, reducing the swing amplitude of the upper cover plate. There is a fourth angle α4 between the extension direction of the fifth guide groove and the lower cover plate. Along the direction from the upper cover plate to the lower cover plate, the first end of the fifth guide groove is close to the rotating shaft relative to the second end of the fifth guide groove. In this way, the fifth guide groove can be tilted, and when the pull rod pushes the lower cover plate connected to the first guide block to move downward, the upper cover plate connected to the fourth guide block can be pushed to move upward. For example, the third angle α3 is greater than or equal to the fourth angle α4. In this way, when the rotating shaft mechanism drives the pull rod to move and drives the upper cover plate to move upward, the upper cover plate will tilt so that there is an angle between the end of the upper cover plate facing the rotating mechanism and the pull rod, thereby increasing the distance between the end of the upper cover plate close to the rotating mechanism and the end of the lower cover plate close to the rotating mechanism, thereby increasing the flow rate of air between the upper cover plate and the lower cover plate, thereby achieving the purpose of improving the heat dissipation efficiency.

[0024] In an optional embodiment, the drive assembly further includes a fourth guide block and a fifth guide rod. The fourth guide block is located on the side of the third guide block away from the rotating mechanism. The fourth guide block is connected to the upper cover plate, and a fifth guide groove is provided on the fourth guide block. The first end of the fifth guide rod is connected to the pull rod, and the second end of the fifth guide rod is located in the fifth guide groove and slidably cooperates with the fifth guide groove. The extension direction of the fifth guide groove is parallel to the extension direction of the pull rod. Similarly, when the rotating shaft mechanism drives the pull rod to move and drives the upper cover plate to move upward, the upper cover plate will tilt so that an angle is formed between the end of the upper cover plate facing the rotating mechanism and the pull rod. In addition, the extension direction of the fifth guide groove is parallel to the extension direction of the pull rod, so that the free end of the fifth guide rod is easier to slide in the fifth guide groove.

[0025] In an optional embodiment, the display screen rotates to drive the first gear to rotate in the same direction as the display screen, and the second gear rotates in the opposite direction to the first gear. Based on this, when the display screen rotates to an open state, the second gear drives the pull rod to move in a direction away from the rotation center of the display screen, the pull rod drives at least a portion of the lower cover plate to move in a direction away from the upper cover plate, and the pull rod also drives the upper cover plate to move in a direction away from the lower cover plate. In this case, the spacing between the upper cover plate and the lower cover plate can be increased. Based on this, when the above-mentioned electronic device adopts an air-cooled heat dissipation method, the air circulation rate in the accommodating cavity can be increased to improve the heat dissipation efficiency. When the display screen rotates to a closed state, the second gear drives the pull rod to move in a direction toward the rotation center of the display screen, the pull rod drives at least a portion of the lower cover plate to move in a direction toward the upper cover plate, and the pull rod also drives the upper cover plate to move in a direction toward the lower cover plate, so that the above-mentioned lower cover plate and the lower cover plate can be restored to their initial positions.

[0026] In an optional embodiment, the electronic device further comprises a fan, which is arranged in the accommodating cavity. A first air outlet is provided on the side of the main housing facing the rotation center of the display screen, and the first air outlet is connected to the accommodating cavity. A first air inlet is provided on the side of the main housing, and the first air inlet is connected to the accommodating cavity; the side is perpendicular to the side of the main housing facing the rotation center of the display screen. Wherein, the vertical projection of the first air inlet on the lower cover plate is located on the side away from the rotating shaft from the vertical projection of the fan on the lower cover plate. In this way, the installation position of the fan can be set between the first air inlet and the first air outlet, so that the setting position of the first air inlet and the setting position of the first air outlet can be physically isolated, avoiding setting the first air inlet and the first air outlet on the same side of the main housing, so that the positions of the first air inlet and the first air outlet are close, resulting in the phenomenon that the hot air discharged from the first air outlet is re-inhaled from the first air inlet into the accommodating cavity, which is beneficial to improve the heat dissipation efficiency of the heat dissipation device.

[0027] In an optional embodiment, the vertical projection of the fan on the lower cover is located within the range of the movable plate. In this way, the fan can be arranged directly above the movable plate, and when the movable plate moves relative to the fixed plate, the fan is rotated, which is conducive to the external cold air entering the accommodating cavity and the hot air inside the accommodating cavity being discharged out of the accommodating cavity.

[0028] In an optional embodiment, a first positioning hole and a second positioning hole may be respectively formed at both ends of the pull rod. In this case, the electronic device may further include two guide posts, such as pins, which pass through the first positioning hole and the second positioning hole respectively and are connected to the upper cover plate, so that when the pull rod is driven and moved by the rotating mechanism, the two pins can slide in the first positioning hole and the second positioning hole, thereby reducing the deviation of the pull rod.

[0029] Another aspect of the present application provides an electronic device, which includes a display screen, a host housing, and a rotating mechanism. The host housing includes an upper cover plate and a lower cover plate connected to each other, and a receiving cavity is formed between the upper cover plate and the lower cover plate, and the host housing is rotatably connected to the display screen. The rotating mechanism is arranged in the receiving cavity, and the rotating mechanism is connected to the display screen and the upper cover plate; when the display screen is in an open state, the rotating mechanism abuts against the lower cover plate. In this way, the distance between the upper cover plate and the lower cover plate can be increased, so as to achieve the purpose of improving the air flow efficiency and the heat dissipation efficiency.

[0030] In an optional embodiment, the electronic device further comprises a rotating shaft, which is connected to the display screen, and the rotating shaft is rotatably connected to the host housing. Wherein, the rotating mechanism comprises a first gear, a second gear and a first abutting portion. The first gear is arranged on the rotating shaft, and the first gear is connected to the rotating shaft. The second gear is meshed with the first gear. The first end of the first abutting portion is connected to the second gear; when the display screen is in an open state, the second end of the first abutting portion abuts against the lower cover plate. In this case, when the display screen is converted from a closed state to an open state, the first gear rotates counterclockwise and the second gear rotates clockwise, thereby driving the first abutting portion to rotate clockwise and abut against the lower cover plate, and the first abutting portion applies a downward force to the lower cover plate. Based on this, since the rotating mechanism is connected to the upper cover plate through the rotating shaft, when the lower cover plate is placed on the desktop, the lower cover plate can apply an upward reaction force to the upper cover plate through the rotating mechanism, thereby driving a part of the upper cover plate to move in a direction away from the lower cover plate, so that the end of the upper cover plate close to the rotating shaft tilts upward, thereby achieving the purpose of increasing the air flow rate in the accommodating chamber.

[0031] In an optional embodiment, the electronic device further includes a fan and a carrier plate. The fan is disposed in the accommodating chamber, the carrier plate is disposed in the accommodating chamber, the fan is mounted on the carrier plate, and one end of the carrier plate away from the rotating shaft is hinged to the main body housing. In addition, the rotating mechanism includes a second abutting portion, the first end of the second abutting portion is connected to the second gear; when the display screen is in an open state, the second end of the second abutting portion abuts against the surface of the carrier plate facing the upper cover plate. In this case, when the display screen is converted from a closed state to an open state, the first gear and the second gear drive the first abutting portion and the second abutting portion to rotate clockwise, and the first abutting portion abuts against the lower cover plate, and the second abutting portion abuts against the carrier plate. The first abutting portion applies a downward force to the lower cover plate, and the second abutting portion applies a downward force to the carrier plate. When the first abutting portion applies a downward force to the lower cover plate, the end of the upper cover plate close to the rotating shaft can tilt upward. In addition, since the end of the carrier plate away from the rotating shaft is hinged to the main body housing, the second abutting portion applies a downward force to the carrier plate, so that the carrier plate rotates relative to the main body housing and the end of the carrier plate close to the rotating shaft can be tilted downward. In this way, the distance between the upper cover plate and the carrier plate can be increased, so as to increase the distance between the upper cover plate and the fan, thereby increasing the flow rate of air between the fan and the upper cover plate, and achieving the purpose of improving the heat dissipation efficiency.

[0032] In an optional embodiment, the electronic device further includes an elastic member, one end of which is connected to the rotating mechanism, and the other end of which is connected to the lower cover. When the upper cover is tilted upward relative to the lower cover, the elastic member can be in a stretched state. When the display screen is converted from an open state to a closed state, the first gear and the second gear drive the first abutment portion and the second abutment portion to rotate counterclockwise, and the first abutment portion no longer abuts against the lower cover, and the second abutment portion no longer abuts against the supporting plate. In this case, the elastic member can pull the end of the lower cover close to the rotating shaft upward under the action of the elastic restoring force, thereby removing the above-mentioned reaction force of the lower cover on the upper cover, so that the upper cover moves downward to return to its initial position.

[0074] In the drawings of the embodiments of the present application, components are represented by guide lines with arrows; parts are represented by guide lines only; and hollow structures such as openings and holes are represented by guide lines with wavy lines at the ends.

[0075] An embodiment of the present application provides an electronic device, which can be applied to various communication systems or communication protocols, such as: Bluetooth (BT) communication technology, global positioning system (GPS) communication technology, global system of mobile communication (GSM) communication technology, wireless fidelity (WiFi) communication technology, wideband code division multiple access wireless (WCDMA) communication technology, long term evolution (LTE), 5G communication technology and other future communication technologies, etc.

[0076] For example, the electronic device may be a computer, such as a desktop computer, a laptop computer, including an ordinary home or commercial laptop computer, or a game book, a mobile phone, a television, a smart wearable product (e.g., a smart watch, a smart bracelet), a virtual reality (VR) electronic device, an augmented reality (AR) electronic device, etc. The embodiments of the present application do not impose any special restrictions on the specific form of the electronic device. For the convenience of explanation, the following description is based on the example of a laptop computer as the electronic device.

[0077] The electronic device 01 provided in this application may include: Figure 1A The host 10 and the display screen 11 shown are rotatably connected. The display screen 11 may include a screen body 110, a top cover (also referred to as an A shell) 111 and a front frame (also referred to as a B shell) 112. 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.

[0078] 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.

[0079] Continue as Figure 1A As 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 relative to the host 10 around the X-axis. In this case, the display screen 11 can have two states relative to the host 10, such as an open state and a closed state. For the convenience of explanation below, an XYZ coordinate system related to the electronic device 01 is established in the accompanying drawings. The X-axis can be the direction of the rotation axis of the display screen 11 when it 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 Figure 1B As shown in the closed state, when the display screen 11 is buckled 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. When the display screen 11 is in the closed state, the display screen 11 is stacked on the host 10 along the Z-axis.

[0080] The following is an example of the closed state and the open state of the display screen 11. Figure 1B As shown, in the closed state, the display screen 11 can be buckled onto the host 10. Figure 1A The front frame 112 of the display screen 11 and the upper cover plate 1011 of the host 10 can be parallel or in contact with each other, and the angle γ (such as Figure 1AWhen the user rotates the display screen 11, one end of the display screen 11 can rotate around Figure 1A The X-axis shown is rotated relative to the host 10. At this time, the angle γ between the display screen 11 and the host 10 gradually increases from the above 0°, so that the display screen 11 is in an open state, which is convenient for the user to see the picture displayed on the display screen 11. In the embodiment of the present application, the angle of rotation of the display screen 11 relative to the host 10, that is, the above angle γ, can be 0° to 180°. When the user is using the electronic device 01, the angle γ between the host 10 and the display screen 11 can be 90° to 135°.

[0081] In addition, continue 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. Figure 1B As shown, when the display screen 11 is in a closed state, the upper cover plate 1011 is arranged close to the display screen 11 relative to the lower cover plate 1012. Figure 2 In addition, the electronic device 01 may also include a keyboard and a control panel (not shown in the figure) disposed on the upper cover 1011, and components such as a processor and a memory (not shown in the figure) disposed in the accommodating cavity 1013. The processor may control the screen body 110 to display.

[0082] 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. In some embodiments of the present application, taking the processor as a heating element, the heating element generates 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 3A 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 (not shown in the figure). Among them, 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. 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.

[0083] 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. 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 2 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.

[0084] As can be seen from the above, the host housing 101 can be rotatably connected to the display screen 11, so that the entire host 10 is rotatably connected to the display screen 11. Based on this, in order to make the host housing 101 rotatably connected to the display screen 11, in some embodiments of the present application, continue as follows Figure 3A (along Figure 1A As shown in the cross-sectional view obtained by cutting along the line Q1-Q2 in FIG. 1 , the electronic device 01 may further include a shaft 50. The shaft 50 may include two oppositely disposed ends, one end of which may be connected to the display screen 11. In addition, the other end of the shaft 50 may be rotatably connected to the host housing 101, for example, the other end of the shaft 50 may be rotatably connected to the upper cover plate 1011 in the host housing 101.

[0085] In this way, when the user rotates the display screen 11, the rotating shaft 50 and the display screen 11 can be driven to rotate relative to the host housing 101, thereby changing the angle γ between the display screen 11 and the host housing 101, so that the display screen 11 rotates to an open state or a closed state. In this case, the rotation center of the display screen 11 can be the axis of the rotating shaft 50. Based on this, in some embodiments of the present application, continue as follows Figure 3A As shown, a first air outlet 32 ​​is provided on one side of the main housing 101 facing the rotation center (i.e., the rotation axis 50) of the display screen 11, and the first air outlet 32 ​​can be connected to the accommodating cavity 1013. A first air inlet 31 is provided on the side of the main housing 101, and the first air inlet 31 is connected to the accommodating cavity 1013. Figure 3AOn the side where the ZY plane is shown, the side surface of the host housing 101 is perpendicular to the side of the host housing 101 facing the rotation center (i.e., the rotation axis 50) of the display screen 11. For example, the first air inlet 31 and the first air outlet 32 ​​can be provided on the upper cover plate 1011 or on the lower cover plate 1012, and this application does not limit this.

[0086] In this case, the fan 203 can transfer the cold air ( Figure 3A The cold air is sucked into the accommodating chamber 1013 (as indicated by the dashed arrow in the figure), so that the cold air can exchange heat with the heat conducting sheet 201, the heat pipe 202 and the heat dissipating fins. The hot air generated after the heat exchange ( Figure 3A The air (as indicated by the solid arrow) can be discharged from the first air outlet 32.

[0087] On this basis, in order to reduce the probability of the hot air discharged from the first air outlet 32 ​​being re-inhaled into the accommodating chamber 1013 from the first air inlet 31, as shown in FIG. Figure 3A As shown, the vertical projection of the first air inlet 31 on the lower cover 1012 can be located on the side away from the rotating shaft 50 from the vertical projection of the fan 203 on the lower cover 1012. In this way, the installation position of the fan 203 can be set between the first air inlet 31 and the first air outlet 32, so that the setting position of the first air inlet 31 and the setting position of the first air outlet 32 ​​can be physically isolated, avoiding setting the first air inlet 31 and the first air outlet 32 ​​on the same side of the host housing 101, so that the positions of the first air inlet 31 and the first air outlet 32 ​​are close, resulting in the phenomenon that the hot air discharged from the first air outlet 32 ​​is re-inhaled from the first air inlet 31 into the accommodating cavity 1013, which is beneficial to improve the heat dissipation efficiency of the heat dissipation device 20.

[0088] In other embodiments of the present application, in order to improve the heat dissipation efficiency of the heat dissipation device 20, as shown in FIG. Figure 3B (along Figure 3A As shown in the schematic diagram obtained from the D direction in FIG. 1 , the electronic device 01 may have two first air inlets 31 and two first air outlets 32. The two first air inlets 31 may be arranged on two opposite sides of the host housing 101, that is, Figure 3B In addition, the two first air outlets 32 may be located on the same side of the host housing 101, that is, both are located on the side of the host housing 101 facing the rotation center of the display screen 11 ( Figure 3B ), which is located at the upper end of Figure 3B At positions ③ and ④ in the figure.

[0089] In addition, if Figure 3AAs shown, there may be a first gap H1 between the fan 203 and the lower cover plate 1012, and the first gap H1 may provide a certain space so that the air in the accommodating cavity 1013 can flow effectively during the rotation of the fan 203. Based on this, in some embodiments of the present application, the air flow speed in the accommodating cavity 1013 may be increased by increasing the first gap H1, thereby improving the heat dissipation efficiency of the heat dissipation device 20. In order to increase the first gap H1, other structures of the electronic device 01 are described below by way of example.

[0090] Specifically, Figure 4 As shown, the electronic device 01 may further include at least one driving component 40 . Figure 4 The electronic device 01 includes two drive assemblies 40 as an example for description. The two drive assemblies 40 can be respectively arranged on both sides of the lower cover 1012 along the X direction. In some embodiments of the present application, any one of the drive assemblies 40 can include a rotating mechanism 401 and a sliding mechanism 402. The rotating mechanism 401 can be connected to the display screen 11. For example, the rotating mechanism 401 is connected to the rotating shaft 50, so that the rotating mechanism 401 can be connected to the display screen 11 through the rotating shaft 50. In this way, during the rotation of the display screen 11, the rotating mechanism 401 can rotate along with the rotation of the display screen 11.

[0091] In addition, the sliding mechanism 402 can be in transmission connection with the rotating mechanism 401, and the sliding mechanism 402 is in sliding cooperation with at least a portion of the lower cover plate 1012. Figure 4 As shown, the rotating mechanism 401 is used to follow the rotation of the display screen 11 and drive the sliding mechanism 402 to move along the Y direction, away from or toward the rotation center of the display screen 11 (i.e., the rotation axis 50). That is, the rotating mechanism 401 can drive the sliding mechanism 402 to move left or right along the Y direction. In addition, the sliding mechanism 402 is used to drive at least a portion of the lower cover plate 1012 to move away from or toward the upper cover plate 1011 ( Figure 3A That is, the sliding mechanism 402 can drive at least a portion of the lower cover plate 1012 to move upward or downward along the Z direction.

[0092] In the embodiment of the present application, the transmission connection refers to the connection between two transmission-connected components, where the active component, such as the rotating mechanism 401, performs mechanical movement, such as rotation (or movement), and can drive the driven component, such as the sliding mechanism 402, to perform mechanical movement, such as movement (or rotation), thereby realizing a mechanical transmission connection relationship, including connection relationships such as snap-in, meshing, abutment, and sliding.

[0093] In summary, Figure 4The display screen 11 is connected to the rotating mechanism 401, so that when the display screen 11 is rotated from the closed state to the open state, the display screen 11 and the host housing 101 (such as Figure 3A The angle γ between the upper and lower covers 1012 increases gradually. The display screen 11 can drive the rotating mechanism 401 to rotate. The rotating mechanism 401 is in transmission connection with the sliding mechanism 402, so that the rotating mechanism 401 can drive the sliding mechanism 402 to move along the Y direction toward or away from the rotation center of the display screen 11, that is, the rotation axis 50. The sliding mechanism 402 is slidably matched with at least a portion of the lower cover plate 1012, so that the sliding mechanism 402 can drive at least a portion of the lower cover plate 1012 downward along the Z direction, that is, away from the rotation center of the display screen 11, when it moves along the Y direction. Figure 3A In this case, the first gap H1 between the fan 203 and the lower cover 1012 can be increased, and the distance between the upper cover 1011 and the lower cover 1012 is increased, which is beneficial to the air circulation in the accommodating cavity 1013 and improves the heat dissipation efficiency.

[0094] In addition, when the display screen 11 rotates from the open state to the closed state, the display screen 11 and the host housing 101 (such as Figure 3A The included angle γ between the two ends of the cover plate 1012 gradually decreases. The sliding mechanism 402 moves along the Y direction under the drive of the rotating mechanism 401, and drives at least a portion of the lower cover plate 1012 upward along the Z direction, that is, toward Figure 3A The upper cover plate 1011 shown moves so that the first gap H1 between the fan 203 and the lower cover plate 1012 returns to an initial value.

[0095] On this basis, in order to further improve the heat dissipation efficiency, in some embodiments of the present application, continue as follows Figure 4 As shown, the lower cover 1012 may include a movable plate (referred to as an E-shell) 10121 and a fixed plate 10122. The movable plate 10121 may be slidably matched with the sliding mechanism 402. Figure 5AAs shown, the vertical projection of the fan 203 on the lower cover plate 1012 overlaps with the movable plate 10121. In this way, the fan 203 can be arranged directly above the movable plate 10121. When the movable plate 10121 moves relative to the fixed plate 10122, the fan 203 is conducive to the external cold air entering the accommodating chamber 1013 and the hot air inside the accommodating chamber 1013 is discharged from the accommodating chamber 1013 during the rotation process. In addition, the fixed plate 10122 can be connected to the upper cover plate 1011, so that the lower cover plate 1012 can be connected to the upper cover plate 1011. The fixed plate 10122 is provided with a mounting hole 10123 which penetrates the fixed plate 10122 , and the movable plate 10121 can be located in the mounting hole 10123 , so that when the sliding mechanism 402 drives the movable plate 10121 , the movable plate 10121 can move upward and downward along the Z direction relative to the fixed plate 10122 , thereby realizing the sliding cooperation between the movable plate 10121 and the sliding mechanism 402 .

[0096] in, Figure 4 When the sliding mechanism 402 shown drives the movable plate 10121, the movable plate 10121 can move up and down relative to the fixed plate 10122 in the Z direction. This may mean that when the sliding mechanism 402 drives the movable plate 10121, the sliding mechanism 402 applies a force to the movable plate 10121, so that the movable plate 10121 moves up and down in the Z direction, while the fixed plate 10122 is fixed. Alternatively, this may mean that when the sliding mechanism 402 drives the movable plate 10121, the sliding mechanism 402 applies a force to the movable plate 10121, so that the fixed plate 10122 moves up and down in the Z direction, while the movable plate 10121 is fixed. The following description is made by taking the movable plate 10121 moving up and down in the Z direction, while the fixed plate 10122 is fixed, as an example.

[0097] In this case, when the display screen 11 is in the Figure 5A In the closed state shown in FIG. 1 , the movable plate 10121 can be located in the mounting hole 10123, and a first gap H1 is provided between the fan 203 and the movable plate 10121. When the display screen 11 is rotated from the closed state to the open state, as shown in FIG. Figure 5B As shown, the angle γ between the display screen 11 and the host housing 101 gradually increases. Figure 4 The rotating mechanism 401 shown in the figure is driven by the display screen 11 to drive the sliding mechanism 402 to move away from or toward the rotating shaft 50 along the Y direction. The sliding mechanism 402 can drive Figure 5B The movable plate 10121 shown moves downward along the Z direction away from the upper cover plate 1011, so that a second gap H2 is formed between the fan 203 and the movable plate 10121. H2>H1, thereby increasing the distance between the fan 203 and the movable plate 10121.

[0098] In this way, continue as Figure 5B As shown, since the movable plate 10121 moves downward along the Z direction, a second air inlet 33 can be formed between the side of the movable plate 10121 close to the first air inlet 31 and the fixed plate 10122, and a second air outlet 34 can be formed between the side of the movable plate 10121 close to the first air outlet 32 ​​and the fixed plate 10122. In this case, during the operation of the fan 203, cold air (as shown by the dotted arrows in the figure) can be sucked into the accommodating cavity 1013 from the first air inlet 31 and the second air inlet 33, and the hot air generated after the heat exchange (as shown by the solid arrows in the figure) can be discharged from the first air outlet 32 ​​and the second air outlet 34, thereby increasing the number of air inlets and air outlets, which is conducive to improving the heat dissipation efficiency. In addition, during the heat dissipation process of the electronic device 01, it is only necessary to drive the movable plate 10121 to move relative to the fixed plate 10122, and the display screen 11 will not be blocked, thereby improving the appearance design effect of the electronic device.

[0099] In addition, if Figure 6 As shown, the second air inlet 33 can be located on both sides of the movable plate 10121, namely, at position ⑤ and position ⑥. The second air outlet 34 can be arranged at the rotation center of the movable plate 10121 toward the display screen 11 ( Figure 6 Therefore, the second air inlet 33 at position ⑤ and position ⑥ can be physically isolated from the second air outlet 34 at position ⑦, thereby avoiding the second air inlet 33 and the second air outlet 34 being arranged on the same side of the host housing 101, so that the second air inlet 33 and the second air outlet 34 are arranged close to each other, resulting in the hot air discharged from the second air outlet 34 being re-inhaled from the second air inlet 33 into the accommodating cavity 1013 (such as Figure 5A The phenomenon shown in FIG. 1 occurs, which is beneficial to improving the heat dissipation efficiency of the heat dissipation device 20.

[0100] The above is based on Figure 4 When the sliding mechanism 402 shown drives the movable plate 10121, the sliding mechanism 402 applies a force to the movable plate 10121, so that the movable plate 10121 moves up and down along the Z direction, while the fixed plate 10122 is fixed. In this case, in order to place the electronic device 01 on a carrier, such as a desktop, there is a certain distance between the movable plate 10121 and the desktop to provide a certain space for the movable plate 10121 to move downward along the Z direction, such as Figure 6 As shown, the electronic device 01 may further include a plurality of foot pads 51, for example, four foot pads 51 respectively disposed at four corners of the fixing plate 10122. In addition, the foot pads 51 may be disposed at the fixing plate 10122 away from the upper cover plate 1011 (eg Figure 5BOne side surface of the device.

[0101] In this case, by adjusting the height of the foot pad 51, the fixed plate 10122 can be supported so that when the display screen 11 is in the closed state, the movable plate 10121 flush with the fixed plate 10122 can have a certain distance from the desktop. The height of the distance can be approximately equal to the height of the foot pad 51. In this way, when the display screen 11 is rotated from the closed state to the open state, the movable plate 10121 can move downward (away from the upper cover plate 1011) within the height range supported by the foot pad 51 to form a Figure 5B The second air inlet 33 and the second air outlet 34 are shown.

[0102] Alternatively, in some other embodiments of the present application, the foot pad 51 may be disposed on the movable plate 10121 away from the upper cover plate 1011 (eg Figure 5B When the electronic device 01 is placed on the desktop, the desktop can support the movable plate 10121 through the foot pad 51. Figure 4 When the sliding mechanism 402 shown drives the movable plate 10121, for example, when the sliding mechanism 402 applies a downward force to the movable plate 10121, the desktop will generate an upward reaction force on the movable plate 10121, and the movable plate 10121 can transmit the above-mentioned upward reaction force to the sliding mechanism 402. Since the sliding mechanism 402 can be indirectly connected to the fixed plate 10122 through the rotating mechanism 401, the above-mentioned upward reaction force can drive the fixed plate 10122 to move along the Z direction. On the contrary, when the sliding mechanism 402 no longer applies a downward force to the movable plate 10121, the fixed plate 10122 moves downward along the Z direction to return to the initial position. Based on this, when the display screen 11 is in a closed state, the fixed plate 10122 flush with the movable plate 10121 can have a certain distance from the above-mentioned desktop. The height of the distance is approximately equal to the height of the foot pad 51. When the display screen 11 is rotated from the closed state to the open state, the sliding mechanism 402 applies a force to the movable plate 10121, so that the fixed plate 10122 moves upward (toward the upper cover plate 1011) relative to the movable plate 10121 within the height range supported by the foot pad 51, thereby forming a Figure 5B The purpose of the second air inlet 33 and the second air outlet 34 shown.

[0103] The structures of the rotating mechanism 401 and the sliding mechanism 402 are described below by way of example. Figure 7As shown, the rotating mechanism 401 may include a first gear 4011 and a second gear 4012. The first gear 4011 may be disposed on a rotating shaft 50, and the first gear 4011 is connected to the rotating shaft 50. For example, the rotating shaft 50 may pass through the center of the first gear 4011 and be key-connected to the first gear 4011. As can be seen from the above, the display screen 11 is connected to the rotating shaft 50, so when the user rotates the display screen 11, the rotating shaft 50 may drive the first gear 4011 to rotate, so that the rotation direction of the first gear 4011 is the same as the rotation direction of the display screen 11, that is, the display screen 11 may drive the first gear 4011 to rotate in the same direction as the display screen 11, that is, the display screen 11 may drive the first gear 4011 to rotate in the same direction as the display screen 11.

[0104] In addition, continue Figure 7 As shown, the second gear 4012 can mesh with the first gear 4011. In this way, the first gear 4011 can be a driving wheel, and the second gear 4012 can be a driven wheel. Therefore, during the rotation of the first gear 4011, the second gear 4012 can be driven to rotate, and the rotation direction of the first gear 4011 is opposite to the rotation direction of the second gear 4012. In addition, the second gear 4012 is transmission-connected with the sliding mechanism 402, so that the entire rotating mechanism 401 can be transmission-connected with the sliding mechanism 402. In this case, under the rotation of the display screen 11, the first gear 4011 can drive the second gear 4012 to rotate, and the second gear 4012 can drive the sliding mechanism 402 transmission-connected with the second gear 4012 to move along the Y direction, away from or toward the direction of the rotating shaft 50.

[0105] For example, when the display screen 11 is Figure 7 As shown in the figure, when the display screen 11 rotates counterclockwise from the closed state to the open state, the display screen 11 can drive the first gear 4011 to rotate counterclockwise. At this time, the second gear 4012 meshing with the first gear 4011 rotates clockwise, thereby driving the sliding mechanism 402 to move away from the rotating shaft 50 in the Y direction, and then the sliding mechanism 402 can drive the movable plate 10121 to move downward in the Z direction.

[0106] On the contrary, when Figure 7 When the display screen 11 shown rotates clockwise from the open state to the closed state, the display screen 11 can drive the first gear 4011 to rotate clockwise. At this time, the second gear 4012 meshing with the first gear 4011 rotates counterclockwise, thereby driving the sliding mechanism 402 to move toward the rotating shaft 50 along the Y direction, and then the sliding mechanism 402 can drive the movable plate 10121 to move upward along the Z direction.

[0107] On this basis, in order to enable the sliding mechanism 402 to be transmission-connected with the second gear 4012 in the rotating mechanism 401, in some embodiments of the present application, for example Fig. 8A As shown, the sliding mechanism 402 may include a pull rod 4021, and the extension direction (along the Y direction) of the pull rod 4021 may be perpendicular to the rotating shaft 50, that is, perpendicular to the axis of the rotating shaft 50. Figure 8B As shown, the end of the pull rod 4021 facing the rotating shaft 50 is provided with a first guide groove 601, and the extension direction of the first guide groove 601 (ie, the guiding direction of the first guide groove 601) is aligned with the upper cover plate 1011 (eg, Figure 5B ) is vertical. In addition, the driving assembly 40 may further include a first guide rod 611, the first guide rod 611 having a first end and a second end arranged opposite to each other. The first end of the first guide rod 611, i.e., the fixed end, is connected to the second gear 4012, and the second end of the first guide rod 611, i.e., the free end, is located in the first guide groove 601 and slidably cooperates with the first guide groove 601. In addition, as described in the following Fig. 8A As shown, the pull rod 4021 is slidably matched with at least a portion of the lower cover plate 1012 , such as the above-mentioned movable plate 10121 , so that the entire sliding mechanism 402 can be slidably matched with the movable plate 10121 .

[0108] In this way, when the display screen 11 is Figure 7 When the display screen 11 rotates counterclockwise from the closed state to the open state, the first gear 4011 can be driven by the display screen 11. Figure 8B At this time, the second gear 4012 meshing with the first gear 4011 rotates clockwise, thereby driving the first guide rod 611 to move downward in the first guide groove 601 along the Z direction. At this time, the pull rod 4021 can be pushed to move away from the rotating shaft 50 along the Y direction, thereby driving Fig. 8A The movable plate 10121 is shown moving downward along the Z direction.

[0109] On the contrary, when Figure 7 When the display screen 11 shown rotates clockwise from the open state to the closed state, the display screen 11 can drive the first gear 4011 to rotate clockwise. At this time, the second gear 4012 meshing with the first gear 4011 rotates counterclockwise, thereby driving the first guide rod 611 to move upward along the Z direction in the first guide groove 601. At this time, the pull rod 4021 can be pulled to move toward the rotating shaft 50 along the Y direction, thereby driving Fig. 8A The movable plate 10121 is shown moving upward along the Z direction.

[0110] Based on this, continue as Fig. 8AAs shown, in order to make the pull rod 4021 move stably along the Y direction under the drive of the rotating mechanism 401 and reduce the displacement of the pull rod 4021 in the XY plane during the movement, the two ends of the pull rod 4021 can respectively open a first positioning hole 4022 and a second positioning hole 4023. In this case, the electronic device 01 can also include two guide posts (not shown in the figure), such as pins, which pass through the first positioning hole 4022 and the second positioning hole 4023 respectively and are connected to the upper cover plate 1011 (such as Figure 5B As shown in the figure, the two pins can slide in the first positioning hole 4022 and the second positioning hole 4023 when the pull rod 4021 moves in the Y direction under the drive of the rotating mechanism 401, thereby reducing the displacement of the pull rod 4021 on the XY plane.

[0111] On this basis, continue Fig. 8A As shown, in order to make the pull rod 4021 and at least a part of the lower cover, such as the above-mentioned movable plate 10121, slide and cooperate, so that when the pull rod 4021 moves away from the rotating shaft 50 along the Y direction, it can be driven Fig. 8A The movable plate 10121 shown in the figure moves downward along the Z direction, and when the pull rod 4021 moves along the Y direction close to the rotating shaft 50, it can drive Fig. 8A The movable plate 10121 shown moves upward along the Z direction. In some embodiments of the present application, the driving assembly 40 may further include a first guide block 403 and a second guide rod 405 .

[0112] Among them, continue as Fig. 8A As shown, the first guide block 403 is connected to at least a portion of the lower cover plate 1012, such as the movable plate 10121. For example, the first guide block 403 can be connected to the movable plate 10121 by threaded connection, clamping or bonding. The first guide block 403 is provided with a second guide groove 4031, and the second guide groove 4031 can penetrate the first guide block 403. The extension direction (i.e., the guiding direction) of the second guide groove 4031 can have a first angle α1 with the lower cover plate 1012, so that the second guide groove 4031 can be tilted relative to the lower cover plate 1012.

[0113] In addition, the second guide rod 405 has a first end and a second end that are arranged opposite to each other. The first end of the second guide rod 405, i.e., the fixed end, can be connected to the pull rod 4021. For example, the fixed end of the second guide rod 405 can be connected to the pull rod 4021 as an integral structure. The second end of the second guide rod, i.e., the free end, can be located in the second guide groove 4031 and slidably cooperate with the second guide groove 4031. In this way, when the pull rod 4021 moves away from or toward the rotating shaft 50 along the Y direction, the second guide rod 405 connected to the pull rod 4021 can be driven to slide in the second guide groove 4031. Since the second guide groove 4031 is arranged obliquely, the pull rod 4021 can drive at least a portion of the lower cover plate (e.g., the movable plate 10121) connected to the first guide block 403 to move up and down along the Z direction.

[0114] On this basis, in order to enable the pull rod 4021 to stably drive the movable plate 10121 to move up and down in the Z direction during the movement in the Y direction, and reduce the swing amplitude of the movable plate 10121 in the XY plane, continue as follows Fig. 8A As shown, the driving assembly 40 may further include a second guide block 404 and a third guide rod 406 .

[0115] The second guide block 404 is located on the side of the first guide block 403 away from the rotating mechanism 401, and a gap may be formed between the second guide block 404 and the first guide block 403, so that the movable plate 10121 is subjected to balanced force in the Y direction. In addition, the second guide block 404 is connected to at least a portion of the lower cover plate 1012, such as the movable plate 10121, and a third guide groove 4041 is provided on the second guide block 404. In some embodiments of the present application, the extension direction (i.e., the guiding direction) of the third guide groove 4041 may have a second angle α2 with the lower cover plate 1012, so that the third guide groove 4041 may be tilted relative to the lower cover plate 1012.

[0116] In addition, the first end and the second end of the third guide rod 406 are arranged opposite to each other. Similarly, the first end (i.e., the fixed end) of the third guide rod 406 is connected to the pull rod 4021. For example, the fixed end of the third guide rod 406 can be connected to the pull rod 4021 as an integral structure. The second end (i.e., the free end) of the third guide rod 406 is located in the third guide groove 4041 and is slidably matched with the third guide groove 4041. Similarly, when the pull rod 4021 moves away from or toward the rotating shaft 50 along the Y direction, the third guide rod 406 connected to the pull rod 4021 can be driven to slide in the third guide groove 4041. Since the third guide groove 4041 is inclined, the pull rod 4021 can drive at least a portion of the lower cover plate 1012 (e.g., the movable plate 10121) connected to the second guide block 404 to move up and down along the Z direction.

[0117] In this way, continue as Fig. 8A As shown, by spacing the first guide block 403 and the second guide block 404 that slide together with the pull rod 4021 in the sliding direction of the pull rod 4021, the stability of the sliding connection between the pull rod 4021 and at least a portion of the lower cover plate 1012 (for example, the movable plate 10121) can be increased, and thus the swing amplitude of the movable plate 10121 in the XY plane when it moves up and down in the Z direction can be reduced during the movement of the pull rod 4021 in the Y direction.

[0118] As can be seen from the above, the extension direction (i.e., the guiding direction) of the second guide groove 4031 can have a first angle α1 with the lower cover plate 1012, and the extension direction (i.e., the guiding direction) of the third guide groove 4041 can have a second angle α2 with the lower cover plate 1012, so the second guide groove 4031 and the third guide groove 4041 are inclined relative to the lower cover plate 1012. The following is an example of the process of the rotating mechanism 401 driving the pull rod 4021, and the pull rod 4021 driving the movable plate 10121 to move up and down along the Z direction according to the parameters such as the size and the inclination direction of the inclination angle of the second guide groove 4031 and the third guide groove 4041.

[0119] In some embodiments of the present application, the second guide groove 4031 and the third guide groove 4041 have the same inclination direction and inclination angle. Fig. 8A As shown, along the lower cover plate 1012 toward the upper cover plate 1011 (as shown Figure 5B ) direction, i.e. along Fig. 8A From bottom to top in the Z direction, the first end (i.e., the lower end) of the second guide groove 4031 is closer to the rotation shaft 50 relative to the second end (i.e., the upper end) of the second guide groove 4031. Also, from bottom to top along the Z direction, the first end (i.e., the lower end) of the third guide groove 4041 is closer to the rotation shaft 50 relative to the second end (i.e., the upper end) of the third guide groove 4041. In addition, the first included angle α1 is equal to or approximately equal to the second included angle α2.

[0120] Based on this, Fig. 9A As shown, when the display screen 11 is in the closed state, the first gear 4011 and the second gear 4012 do not rotate, and the pull rod 4021 is in a stationary state. At this time, the free end of the second guide rod 405 connected to the pull rod 4021 is located at the lower end of the second guide groove 4031, and the third guide rod 406 connected to the pull rod 4021 is located at the lower end of the third guide groove 4041.

[0121] like Fig. 9BAs shown, when the display screen 11 rotates counterclockwise, the display screen 11 changes from the above-mentioned closed state to the open state. The display screen 11 can drive the first gear 4011 to rotate counterclockwise during the rotation. At this time, the second gear 4012 meshing with the first gear 4011 rotates clockwise. At this time, the first guide rod 611 connected to the second gear 4012 slides in the first guide groove 601 from top to bottom along the Z direction. The second gear 4012 can be located at the lower end of the first guide groove 601, so that in the process of the first guide rod 611 sliding downward, it can drive the pull rod 4021 to move away from the rotating shaft 50 along the Y direction (that is, move to the right along the arrow). The pull rod 4021 moves along Fig. 9B During the movement to the right in the direction shown, the second guide rod 405 and the third guide rod 406 connected to the pull rod 4021 also move to the right following the pull rod 4021 .

[0122] Based on this, when the second guide rod 405 and the third guide rod 406 move to the right, they need to slide in the second guide groove 4031 and the third guide groove 4041 respectively. Since the second guide groove 4031 and the third guide groove 4041 are inclined, and the lower ends of the second guide groove 4031 and the third guide groove 4041 are close to the rotating mechanism 401, and the upper ends of the second guide groove 4031 and the third guide groove 4041 are far away from the rotating mechanism 401, the second guide rod 405 can apply a downward force to the first guide block 403 when it moves to the right. Similarly, when the third guide rod 406 moves to the right, it can apply a downward force to the second guide block 404.

[0123] In this way, if Fig. 10A As shown, when the display screen 11 is in the open state, it can be seen from the above that the display screen 11 is driven Fig. 9B The first gear 4011 shown rotates in the same direction as the display screen 11, and the first gear 4011 drives the second gear 4012 to rotate in the opposite direction to the first gear 4011. When the second gear 4012 drives the pull rod to move away from the rotating shaft 50 along the Y direction, Fig. 10A The movable plate 10121 connected to the first guide block 403 and the second guide block 404 moves downward along the Z direction relative to the fixed plate 10122, thereby forming the second air inlet 33 and the second air outlet 34. Fig. 10B As shown, the first guide rod 611 connected to the second gear 4012 can be located at the lower end of the first guide groove 601. In addition, the second guide rod 405 connected to the pull rod 4021 is located at the upper end of the second guide groove 4031 opened on the first guide block 403. Similarly, the third guide rod 406 connected to the pull rod 4021 is located at the upper end of the third guide groove 4041 opened on the second guide block 404. In this case, the display screen 11 and the host housing 101 (as shown in FIG. Figure 5B The angle γ between the two sides (as shown) can be 90° to 135°, so that the electronic device 01 is in a state of being used by the user.

[0124] On the contrary, when Fig. 9B When the display screen 11 rotates clockwise from the open state to the closed state, the display screen 11 can drive the first gear 4011 to rotate clockwise. At this time, the second gear 4012 meshing with the first gear 4011 rotates counterclockwise, thereby driving the first guide rod 611 to move upward along the Z direction in the first guide groove 601. At this time, the pull rod 4021 can be pulled to move toward the rotating shaft 50 along the Y direction, so that the second guide rod 405 and the third guide rod 406 move to the left, driving the movable plate 10121 to move upward along the Z direction. In addition, when the display screen 11 is in the closed state, as shown in FIG. Fig. 9A As shown, the second guide rod 405 and the third guide rod 406 are located at the lower ends of the second guide groove 4031 and the third guide groove 4041, respectively. Fig. 9B The movable plate 10121 shown is flush with the fixed plate 10122.

[0125] The above is based on Fig. 9B The second guide groove 4031 and the third guide groove 4041 are shown to have the same inclination direction and inclination angle, and the second guide groove 4031 and the third guide groove 4041 are inclination directions such that the lower ends of the second guide groove 4031 and the third guide groove 4041 are close to the rotation shaft 50, and the upper ends are away from the rotation shaft 50, so that when the display screen 11 is in the open state, the pull rod 4021 moves away from the rotation shaft 50 along the Y direction to drive Fig. 9B The movable plate 10121 shown moves downward along the Z direction, and when the display screen 11 rotates from the open state to the closed state, the pull rod 4021 moves toward the rotating shaft 50 along the Y direction, and the description is made by taking the example of driving the movable plate 10121 to move upward along the Z direction.

[0126] In other embodiments of the present application, Fig.11A As shown in the figure, when the inclination direction and inclination angle of the second guide groove 4031 and the third guide groove 4041 are the same, the inclination direction of the second guide groove 4031 and the third guide groove 4041 is along the lower cover plate 1012 pointing to the upper cover plate 1011, and the lower ends of the second guide groove 4031 and the third guide groove 4041 are away from the rotating shaft 50, and the upper ends are close to the rotating shaft 50, so that when the display screen 11 is in the open state, the pull rod 4021 moves along the Y direction toward the rotating shaft 50 to drive Fig.11AThe movable plate 10121 shown moves downward along the Z direction, and when the display screen 11 rotates from an open state to a closed state, the pull rod 4021 moves away from the rotating shaft 50 along the Y direction to drive the movable plate 10121 to move upward along the Z direction and be flush with the fixed plate 10122.

[0127] Specifically, Fig.11A As shown, when the display screen 11 rotates counterclockwise, the display screen 11 changes from a closed state to an open state. During the rotation of the display screen 11, the first gear 4011 can be driven to rotate counterclockwise and the second gear 4012 can be driven to rotate clockwise. At this time, the first guide rod 611 slides from top to bottom in the first guide groove 601 along the Z direction. The second gear 4012 can be located at the upper end of the first guide groove 601, thereby driving the pull rod 4021 to move toward the rotating shaft 50 along the Y direction (i.e., move to the left along the arrow) during the downward sliding of the first guide rod 611. The pull rod 4021 moves along the Z direction. Fig.11A During the movement to the left in the direction shown, the second guide rod 405 and the third guide rod 406 connected to the pull rod 4021 also move to the left along with the pull rod 4021 .

[0128] At this time, since the second guide groove 4031 and the third guide groove 4041 are inclined, and the upper ends of the second guide groove 4031 and the third guide groove 4041 are close to the rotating mechanism 401, and the lower ends are far away from the rotating mechanism 401, the second guide rod 405 and the third guide rod 406 can respectively apply downward force to the first guide block 403 and the second guide block 404 during the movement to the left, so that the movable plate 10121 moves downward along the Z direction relative to the fixed plate 10122, so as to form the following Fig. 11B The second air inlet 33 and the second air outlet 34 are shown. At this time, the display screen 11 is in the open state, so that the electronic device 01 is in the state of user use. Fig. 11B The display screen 11 rotates clockwise from an open state to a closed state. The movement modes of the rotating mechanism 401, the pull rod 4021, the second guide rod 405 and the third guide rod 406 can be obtained in the same way, which will not be described again here.

[0129] The above is an example of the inclination direction of the second guide groove 4031 and the third guide groove 4041. The present application does not limit the inclination direction of the second guide groove 4031 and the third guide groove 4041. For the convenience of description, the inclination direction of the second guide groove 4031 and the third guide groove 4041 is taken as an example. Fig. 9B The second guide groove 4031 and the third guide groove 4041 shown in the figure have lower ends close to the shaft 50 and upper ends far from the shaft 50. Based on this, the above description is based on the second guide groove 4031 and the third guide groove 4041 having the same inclination angle, that is, Fig. 8A The first angle α1 and the second angle α2 shown in the figure are equal or approximately equal to each other. In other embodiments of the present application, Fig. 12A As shown, the first angle α1 may be greater than the second angle α2, that is, α1>α2.

[0130] In this case, continue as Fig. 12A As shown in FIG. 1 , when the display screen 11 rotates counterclockwise and changes from the closed state to the open state, the display screen 11 drives the first gear 4011 to rotate counterclockwise, and the second gear 4012 to rotate clockwise, driving the pull rod 4021 to move away from the rotating shaft 50 along the Y direction. The second guide rod 405 and the third guide rod 406 connected to the pull rod 4021 move to the right, and the movable plate 10121 moves downward along the Z axis. Next, as shown in FIG. Fig. 12B As shown in FIG. 1 , when the display screen 11 is in the open state, the second guide rod 405 and the third guide rod 406 are respectively located at the upper ends of the second guide groove 4031 and the third guide groove 4041. At this time, since α1>α2, Fig. 12B As shown, after the movable plate 10121 moves downward, the movable plate 10121 tilts, so that an angle θ is formed between the end of the movable plate 10121 facing the rotating mechanism 401 and the fixed plate 10122. In this way, the opening area of ​​the second air inlet 33 can be increased, thereby increasing the air intake volume, which is beneficial to improving the heat dissipation efficiency.

[0131] Or, in other embodiments of the present application, Fig.13 As shown, the extension direction (i.e., the guiding direction) of the third guide groove 4041 is parallel to the extension direction of the pull rod 4021, i.e., the Y direction. Similarly, when the rotating mechanism 401 drives the pull rod 4021 to move along the Y direction and drives the movable plate 10121 to move downward, the movable plate 10121 will also tilt, so that an angle θ is formed between the end of the movable plate 10121 facing the rotating mechanism 401 and the fixed plate 10122, thereby increasing the opening area of ​​the second air inlet 33 and the air intake volume. In addition, the extension direction of the third guide groove 4041 is parallel to the extension direction of the pull rod 4021, so that the free end of the third guide rod 406 can slide more easily in the third guide groove 4041.

[0132] The above description is based on an example in which the driving assembly 40 has two guide blocks connected to the movable plate 10121, for example, the first guide block 403 and the second guide block 404, and two guide rods connected to the pull rod 4021, for example, the second guide rod 405 and the third guide rod 406. The present application does not limit the number of the guide blocks and guide rods. For example, in other embodiments of the present application, Fig.14As shown, the driving assembly 40 may include a guide block connected to the movable plate 10121, such as a first guide block 403, and a guide rod connected to the pull rod 4021, such as a second guide rod 405, and the second guide rod 405 is slidably matched with a second guide groove 4031 provided on the first guide block 403. The schemes of sliding match of other numbers of guide blocks and guide rods can be obtained in the same way, and will not be described one by one here. For the convenience of description, the following description is based on the example that the driving assembly 40 includes the above two guide blocks and two guide rods.

[0133] The above is based on Fig.11A The second gear 4012 in the transmission mechanism 401 shown in the figure slides with the first guide slot 601 on the pull rod 4021 in the sliding mechanism 402 through the first guide rod 611 connected to the second gear 4012, so as to realize the transmission connection between the transmission mechanism 401 and the sliding mechanism 402. In other embodiments of the present application, in order to make the transmission mechanism 401 transmission-connected with the sliding mechanism 402, as shown in FIG. Fig.15 As shown, the sliding mechanism 402 may include a pull rod 4021 and a rack 4024. The first end (eg Fig.15 The left end of the rack 4024 may be meshed with the second gear 4012. Fig.15 The right end of the pull rod 4021 can be connected to the end of the pull rod 4021 facing the rotating shaft 50. The pull rod 4021 is as described above, and its extension direction is perpendicular to the rotating shaft 50, and the pull rod 4021 can be slidably matched with at least a portion of the lower cover 1012, such as the movable plate 10121. The manner in which the pull rod 4021 and the movable plate 10121 are slidably matched is as described above, and will not be repeated here. For the convenience of explanation, the following is an example of the pull rod 4021 slidingly matching with the movable plate 10121 through the first guide block 403, the second guide block 404, the second guide rod 405 and the third guide rod 406.

[0134] Based on this, Fig.16AAs shown, when the display screen 11 rotates counterclockwise to change from a closed state to an open state, the first gear 4011 can be driven to rotate counterclockwise and the second gear 4012 can be driven to rotate clockwise. At this time, the rack 4024 meshing with the second gear 4012 moves away from the rotating shaft 50 along the Y direction, that is, moves to the right, so that the pull rod 4021 connected to the rack 4024 moves away from the rotating shaft 50 along the Y direction. Next, as described above, the second guide rod 405 and the third guide rod 406 connected to the pull rod 4021 move to the right following the pull rod 4021. While the second guide rod 405 and the third guide rod 406 slide in the second guide groove 4031 and the third guide groove 4041, respectively, they apply downward force to the first guide block 403 and the second guide block 404, respectively, so that the movable plate 10121 moves downward along the Z direction relative to the fixed plate 10122. In this way, as described above, Fig. 16B As shown, a second air inlet 33 and a second air outlet 34 may be formed.

[0135] On the contrary, when the display screen 11 rotates clockwise from the open state to the closed state, the display screen 11 can drive the first gear 4011 to rotate clockwise and the second gear 4012 to rotate counterclockwise. At this time, the rack 4024 meshed with the second gear 4012 moves toward the rotating shaft 50 along the Y direction (i.e., moves to the left), thereby pulling the pull rod 4021 to move toward the rotating shaft 50 along the Y direction, so that the second guide rod 405 and the third guide rod 406 move to the left, driving the movable plate 10121 to move upward along the Z direction and be flush with the fixed plate 10122.

[0136] The above is an example of the transmission connection between the transmission mechanism 401 and the sliding mechanism 402, and does not constitute a limitation on the transmission connection between the two. Fig.11A The second gear 4012 in the transmission mechanism 401 shown is slidably matched with the first guide rod 611 connected to the second gear 4012 and the first guide groove 601 on the pull rod 4021 in the sliding mechanism 402 to achieve the transmission connection between the transmission mechanism 401 and the sliding mechanism 402.

[0137] In addition, the above is an example of the lower cover plate 1012 including a movable plate 10121 and a fixed plate 10122, and when the sliding mechanism 402 drives the movable plate 10121, the movable plate 10121 and the fixed plate 10122 move relative to each other along the Z direction. In other embodiments of the present application, the lower cover plate 1012 may be a whole plate-like structure, and the sliding mechanism 402 may drive the entire lower cover plate 1012 to move up and down along the Z direction. The present application does not limit the structure of the lower cover plate 1012.

[0138] Alternatively, in some other embodiments of the present application, the pull rod 4021 may also be Fig.17A The upper cover plate 1011 shown in the figure is slidably matched, so that when the display screen 11 is rotated from the closed state to the open state, the sliding mechanism 402 driven by the rotating mechanism 401 can simultaneously drive the upper cover plate 1011 and the lower cover plate 1012 to move in opposite directions in the Z direction. Fig.17A As shown, the driving assembly may further include a third guide block 407 and a fourth guide rod 408 .

[0139] The third guide block 407 may be connected to the upper cover plate 1011, for example, the third guide block 407 may be connected to the upper cover plate 1011 by threaded connection, clamping or bonding. A fourth guide groove 4071 is provided on the third guide block 407, and the fourth guide groove 4071 may penetrate the third guide block 407. The extension direction (i.e., the guiding direction) of the fourth guide groove 4071 may have a third angle α3 with the upper cover plate 1011, so that the fourth guide groove 4071 may be inclined relative to the upper cover plate 1011.

[0140] Based on this, in order to enable the pull rod 4021 to move in the Y direction, the upper cover plate 1011 and the lower cover plate 1012 can be driven to move in opposite directions in the Z direction, such as Fig.17A As shown, the extension direction of the fourth guide groove 4071 intersects with the extension direction of the second guide groove 4031, so that the inclination direction of the fourth guide groove 4071 is opposite to the inclination direction of the second guide groove 4031. For example, along the direction from the lower cover plate 1012 to the upper cover plate 1011 (i.e., from bottom to top along the Z direction), when the first end (i.e., the lower end) of the second guide groove 4031 approaches the shaft 50 relative to the second end (i.e., the upper end) of the second guide groove 4031, along the direction from the upper cover plate 1011 to the lower cover plate 1012 (i.e., from top to bottom along the Z direction), the first end (i.e., the upper end) of the fourth guide groove 4071 approaches the shaft 50 relative to the second end (lower end) of the fourth guide groove 4071. In addition, as continued Fig.17A As shown, the fourth guide rod 408 has a first end and a second end that are relatively set. The first end of the fourth guide rod 408, that is, the fixed end can be connected to the pull rod 4021, and the second end of the fourth guide rod 408, that is, the free end can be located in the fourth guide groove 4071 and slidably cooperate with the fourth guide groove 4071.

[0141] In this way, if Fig. 17BAs shown, when the display screen 11 rotates counterclockwise to change from the closed state to the open state, the pull rod 4021 moves away from the rotating shaft 50 along the Y direction (i.e., moves to the right) under the drive of the rotating mechanism 401, and can drive the fourth guide rod 408 connected to the pull rod 4021 to slide in the fourth guide groove 4071. Since the fourth guide groove 4071 is inclined, and the inclination direction of the fourth guide groove 4071 is opposite to the inclination direction of the second guide groove 4031, the pull rod 4021 can push the upper cover plate 1011 connected to the third guide block 407 to move along the Z direction while pushing the lower cover plate 1012 connected to the first guide block 403 to move downward along the Z direction. On the contrary, when the display screen 11 rotates clockwise from the open state to the closed state, under the drive of the rotating mechanism 401, the pull rod 4021 pushes the lower cover plate 1012 to move upward along the Z direction, and at the same time, the upper cover plate 1011 connected to the third guide block 407 can be pushed to move downward along the Z direction. Therefore, the relative movement directions of the upper cover plate 1011 and the lower cover plate 1012 are opposite.

[0142] On this basis, in order to enable the pull rod 4021 to stably drive the upper cover plate 1011 to move up and down in the Z direction during the movement in the Y direction, and reduce the swing amplitude of the upper cover plate 1011 in the XY plane, continue as follows Fig.17A As shown, the driving assembly 40 may further include a fourth guide block 409 and a fifth guide rod 410 .

[0143] The fourth guide block 409 is located on the side of the third guide block 407 away from the rotating mechanism 401, and there may be a gap between the fourth guide block 409 and the third guide block 407. In addition, the fourth guide block 409 may be connected to the upper cover plate 1011, and a fifth guide groove 4091 is provided on the fourth guide block 409. The fifth guide rod 410 may have a first end and a second end that are arranged opposite to each other, and the first end of the fifth guide rod 410, that is, the fixed end, may be connected to the pull rod 4201. For example, the fixed end of the fifth guide rod 410 may be connected to the pull rod 4021 as an integral structure. The second end of the fifth guide rod 410, that is, the free end, may be located in the fifth guide groove 4091 and slidably cooperate with the fifth guide groove 4091. Similarly, when the pull rod 4021 moves away from or toward the rotating shaft 50 along the Y direction, the fifth guide rod 410 connected to the pull rod 4021 may be driven to slide in the fifth guide groove 4091.

[0144] Based on this, in some embodiments of the present application, Fig. 17BAs shown, the extension direction (i.e., the guiding direction) of the fifth guide groove 4091 can be parallel to the extension direction of the pull rod 4201, i.e., the Y direction. Similarly, when the rotating mechanism 401 drives the pull rod 4021 to move along the Y direction and drives the upper cover plate 1011 to move upward, the upper cover plate 1011 will tilt, so that an angle δ1 is formed between the end of the upper cover plate 1011 facing the rotating mechanism 401 and the pull rod 4021. In addition, since the extension direction of the fifth guide groove 4091 is parallel to the extension direction of the pull rod 4021, the free end of the fifth guide rod 410 can slide more easily in the fifth guide groove 4061. As can be seen from the above, when the extension direction of the third guide groove 4041 (i.e., the guide direction) is parallel to the extension direction of the pull rod 4201, i.e., the Y direction, the pull rod 4021 moves along the Y direction and drives the lower cover plate 1012 to move downward, and the lower cover plate 1012 will tilt, so that an angle δ2 is formed between the end of the lower cover plate 1012 facing the rotating mechanism 401 and the pull rod 4021. In this way, the distance between the end of the upper cover plate 1011 close to the rotating mechanism 401 and the end of the lower cover plate 1012 close to the rotating mechanism 401 can be increased, so that the flow rate of the air between the upper cover plate 1011 and the lower cover plate 1012 can be increased, so as to achieve the purpose of improving the heat dissipation efficiency.

[0145] Or, in other embodiments of the present application, Fig.18 As shown, the fifth guide groove 4091 can be arranged at an angle. For example, the extension direction (i.e., the guiding direction) of the fifth guide groove 4091 can have a fourth angle α4 with the upper cover plate 1011. The inclination direction of the fifth guide groove 4091 can be in the direction from the upper cover plate 1011 to the lower cover plate 1012 (i.e., from top to bottom along the Z direction), and the first end (upper end) of the fifth guide groove 4091 is close to the rotating shaft 50 relative to the second end (lower end) of the fifth guide groove 4091. In this case, the third angle α3 can be greater than the fourth angle α4, i.e., α3>α4. Similarly, in this way, when the rotating mechanism 401 drives the pull rod 4021 to move along the Y direction and drives the upper cover plate 1011 to move upward, as shown in FIG. Fig. 17B As shown, the upper cover plate 1011 is tilted so that an angle δ1 is formed between the end of the upper cover plate 1011 facing the rotating mechanism 401 and the pull rod 4021 .

[0146] As can be seen from the above, the air inlet of the electronic device 01 is arranged on the side of the electronic device 01, such as Fig.19A As shown, when the upper cover 1011 is close to the rotating shaft 50 (or Fig.17A When one end of the rotating mechanism 401 shown in FIG. 1 is tilted upward along the Z direction, and one end of the lower cover plate 1012 close to the rotating shaft 50 is tilted downward along the Z direction, the openings of the air inlets at positions ① and ② are enlarged, thereby increasing the amount of cold air (indicated by the dotted arrow) entering the air. Fig.19AAs shown in FIG. 1 , an air outlet is added at a position of the main housing 101 close to the rotating shaft 50, i.e., position ③, so that hot air (indicated by a solid arrow) can be quickly discharged from the main housing 101. Based on this, the hot air (indicated by a solid arrow) discharged from the air outlet added at position ③ can be as follows Fig.19B As shown, the hot air is discharged from between the upper cover plate 1011 and the display 11. In addition, due to the inclination of the lower cover plate 1012, the opening of the first air outlet 32 ​​is enlarged, which can also increase the discharge speed of the hot air and improve the heat dissipation efficiency. Fig.19C As shown, the upper cover plate 1011 and the lower cover plate 1012 are in an approximately parallel state.

[0147] The above embodiment is an example of the sliding mechanism 402 driving at least a part of the lower cover plate 1012, or the lower cover plate 1012 and the upper cover plate 1011. In other embodiments of the present application, the sliding mechanism 402 can also only drive the upper cover plate 1011 to translate or tilt upward along the Z direction. The setting method of the sliding mechanism 402 and the rotating mechanism 401 connected to the sliding mechanism 402 is the same as described above, and will not be repeated here.

[0148] In addition, the above embodiment is described by taking the example that the driving assembly 40 includes the rotating mechanism 401 and the sliding mechanism 402, and taking the example that at least one of the lower cover plate 1012 and the upper cover plate 1011 in the host housing 101 is translated or tilted along the Z direction. Fig. 20 The embodiment shown includes the display screen 11, the main body housing 101, the heat dissipation device, the rotating shaft 50 and the rotating mechanism 401, which is arranged in the accommodating cavity 1013 and connected to the display screen 11. The difference from the above embodiment is that when the display screen 11 is in the open state, the rotating mechanism 401 can abut against the lower cover plate 1012. In this way, the distance between the upper cover plate 1011 and the lower cover plate 1012 can be increased, so as to achieve the purpose of improving the air flow efficiency and the heat dissipation efficiency.

[0149] For example, in order to make the rotating mechanism 401 contact with the lower cover plate 1012, continue as follows Fig. 20As shown, the rotating mechanism 401 may include a first gear 4011, a second gear 4012 and a first abutting portion 4013. The first gear 4011 and the second gear 4012 are arranged in the same manner as described above, that is, the first gear 4011 is arranged on the rotating shaft 50 and connected to the rotating shaft, and the second gear 4012 is meshed with the first gear 4011. In addition, the first abutting portion 4013 includes a first end and a second end, and the first end (i.e., the fixed end) of the first abutting portion 4013 is connected to the second gear 4012. In addition, when the display screen 11 is in the open state, the second end (i.e., the free end) of the first abutting portion 4013 can abut against the lower cover plate 1012.

[0150] In this case, for example, continue as Fig. 20 As shown, when the display screen 11 rotates counterclockwise to change from a closed state to an open state, the first gear 4011 rotates counterclockwise, and the second gear 4012 meshing with the first gear 4011 rotates clockwise, thereby driving the first abutment portion 4013 to rotate clockwise and abut against the lower cover plate 1012, and the first abutment portion 4013 applies a downward force along the Z direction to the lower cover plate 1012. Based on this, since the rotating mechanism 401 is connected to the upper cover plate 1011 through the rotating shaft 50, when the lower cover plate 1012 is placed on the desktop and the first abutment portion 4013 applies a downward force along the Z direction to the lower cover plate 1012, the desktop will generate an upward reaction force along the Z direction. The reaction force can be transmitted to the upper cover plate 1011 through the lower cover plate 1012 and the rotating mechanism 401, thereby driving a part of the upper cover plate 1011 to move in a direction away from the lower cover plate 1012, so that the end of the upper cover plate 1011 close to the rotating shaft 50 tilts upward, thereby achieving the purpose of increasing the air flow rate in the accommodating chamber 1013.

[0151] On this basis, in other embodiments of the present application, such as Fig.21A As shown, the electronic device may further include a carrier plate 4014, which may be located in the accommodating cavity 1013, and the fan 203 may be disposed on the carrier plate 4014, and one end of the carrier plate 4014 (the right end in the figure) away from the rotating shaft 50 may be hinged to the host housing 101, for example, the lower cover plate 1012 in the host housing 101. Based on this, in order to increase the spacing between the upper cover plate 1011 and the fan 203, the rotating mechanism 401 may further include a second abutting portion 4015. The second abutting portion 4015 may include a first end and a second end that are relatively arranged, and the first end (i.e., the fixed end) of the second abutting portion 4015 may be connected to the second gear 4012. In addition, when the display screen 11 is in an open state, the second end (i.e., the free end) of the second abutting portion 4015 may abut against the surface of the carrier plate 4014 facing the upper cover plate 1101.

[0152] In this case, continue as Fig.21A As shown, when the display screen 11 rotates counterclockwise to switch from the closed state to the open state, the first gear 4011 rotates counterclockwise, and the second gear 4012 meshing with the first gear 4011 rotates clockwise, thereby driving the first abutting portion 4013 and the second abutting portion 4015 to rotate clockwise, and the first abutting portion 4013 abuts against the lower cover plate 1012, and the second abutting portion 4015 abuts against the supporting plate 4014. The first abutting portion 4013 applies a force downward along the Z direction to the lower cover plate 1012, and the second abutting portion 4015 applies a force downward along the Z direction to the supporting plate 4014.

[0153] Based on this, it can be known from the above that when the first abutting portion 4013 applies a force downward along the Z direction to the lower cover plate 1012, the end of the upper cover plate 1011 close to the rotating shaft 50 can be tilted upward along the Z direction. In addition, since the end of the supporting plate 4014 away from the rotating shaft 50 (the right end in the figure) is hinged to the host housing 101, the second abutting portion 4015 applies a force downward along the Z direction to the supporting plate 4014, so that the supporting plate 4014 rotates relative to the host housing 101, and the end of the supporting plate 4014 close to the rotating shaft 50 can be tilted downward along the Z direction. In this way, the distance between the upper cover plate 1011 and the supporting plate 4014 can be increased, so as to increase the distance between the upper cover plate 1011 and the fan 203, thereby increasing the flow rate of the air between the fan 203 and the upper cover plate 1011, and achieving the purpose of improving the heat dissipation efficiency.

[0154] On this basis, if Fig.21A As shown, the electronic device 01 may further include an elastic member 70. For example, the elastic member 70 may be a coil spring, a rubber spring, etc. One end (for example, the upper end) of the elastic member 70 is connected to the rotating mechanism 401, and the other end (for example, the lower end) of the elastic member 70 may be connected to the lower cover plate 1012. When the upper cover plate 1011 is tilted upward along the Z direction relative to the lower cover plate 1012, the elastic member 70 may be in a stretched state.

[0155] In addition, if Fig.21B As shown, when the display screen 11 rotates clockwise to change from the open state to the closed state, the first gear 4011 rotates clockwise, and the second gear 4012 meshing with the first gear 4011 rotates counterclockwise, thereby driving the first abutting portion 4013 and the second abutting portion 4015 to rotate counterclockwise, and the first abutting portion 4013 no longer abuts against the lower cover plate 1012, and the second abutting portion 4015 no longer abuts against the bearing plate 4014. In this case, the elastic member 70 can pull the end of the lower cover plate 1012 close to the rotating shaft 50 upward along the Z direction under the action of the elastic restoring force, thereby removing the lower cover plate 1012 from the upper cover plate 1011 (as shown in FIG. Fig.21AThe above-mentioned reaction force (as shown) causes the upper cover plate 1011 to move downward along the Z direction to return to its initial position.

[0156] The above is an example of the heat dissipation method of the electronic device 01 taking the electronic device 01 as a notebook. When the electronic device is a desktop computer, a mobile phone or other device, the above heat dissipation method and structure are also applicable.

[0157] 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 should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
