Description

Technical Field

[0001] This application relates to the field of electronic products, and particularly to an electronic device and a display component. Background Art

[0002] Currently, consumers are increasingly concerned about the size and weight of electronic devices. Therefore, being thin and light has become one of the factors to measure the quality of electronic devices. A laptop computer is a widely used electronic device, which includes a display component and a host component. The two are rotationally connected through a hinge structure so that it can be in an open state and a closed state. Currently, the reduction of the thickness of a laptop computer is mainly achieved by reducing the size of the hinge structure, but this method has limited effect on reducing the thickness of the laptop computer. Therefore, how to further reduce the thickness of a laptop computer has been a problem that those skilled in the art have been concerned about. Summary of the Invention

[0003] Embodiments of this application provide an electronic device and a display component with a relatively thin overall thickness and better working performance.

[0004] In a first aspect, embodiments of this application provide an electronic device, including:

[0005] A display component, including a display housing and a display screen. The display screen includes a display panel and a circuit board assembly. The display panel and the display housing enclose a cavity, and the circuit board assembly is located in the cavity;

[0006] A host component, including a host housing and a keyboard. The host housing includes a keyboard mounting surface;

[0007] A hinge structure. The display housing and the host housing are rotationally connected through the hinge structure so that the electronic device can be in an open state and a closed state; when the electronic device is in the closed state, the display panel and the keyboard mounting surface are arranged at an angle, and along the direction from the opening and closing end of the electronic device to the hinge structure, the distance between the display panel and the keyboard mounting surface increases.

[0008] Compared with the prior art where the display panel is arranged parallel to the keyboard mounting surface, the display panel in the embodiments of this application is inclined relative to the first closed surface, making full use of the gap size between the circuit board assembly and the display housing. On the premise of ensuring the normal operation of the circuit board assembly, the size of the circuit board assembly and the display housing in the thickness direction is minimized as much as possible, achieving the effect of increasing the distance between the display panel and the keyboard. In this way, the position of the keyboard can be lifted upward relative to the host housing, reducing the occupation of the internal space of the host housing, which is beneficial to optimizing the layout of other electronic components inside the host housing, and further reducing the thickness of the host component, meeting the requirement of the thin and light design of the electronic device.

[0009] Furthermore, by reducing the thickness of the electronic device through the method provided in the embodiments of the present application, there is no need to sink the hinge structure of the vertical laptop computer to the side of the host assembly, which does not affect the arrangement of heat dissipation structures such as the heat dissipation fan and heat dissipation holes, nor does it block the air output of the heat dissipation fan, thereby further improving the overall performance of the laptop computer.

[0010] In one feasible embodiment, a groove is further provided on the surface of the display housing facing the display screen, the notch of the groove being opposite the circuit board assembly, and the distance between the circuit board assembly and the bottom wall of the groove being within a predetermined range. In this embodiment of the present application, the minimum distance between the circuit board assembly and the first housing is the distance between the circuit board assembly and the bottom of the groove. This increases the inclination angle of the display panel relative to the keyboard mounting surface, facilitating a larger distance between the display panel and the keyboard, increasing the height of the keyboard, and further reducing the keyboard's internal space occupied by the keyboard, thereby reducing the overall thickness of the electronic device.

[0011] In one feasible embodiment, the host assembly further includes a motherboard and a cooling fan. The cooling fan's air outlet faces the motherboard to dissipate heat from the motherboard. On a plane parallel to the keyboard mounting surface, the cooling fan's projection is at least partially or completely within the keyboard's projection. Placing the cooling fan completely or partially directly below the keyboard fully utilizes the space below the keyboard, allowing for a larger, higher-power cooling fan to improve cooling efficiency for the motherboard. Of course, the number of cooling fans can also be increased to further improve cooling efficiency for the motherboard.

[0012] In one feasible embodiment, a heat dissipation module is further included. The heat dissipation pipe comprises a first pipe section and a second pipe section connected by a fluid medium. The first pipe section overlaps the mainboard, and the second pipe section is located on the side of the cooling fan away from the coupling end. The addition of the heat dissipation module in this embodiment can further improve heat dissipation in localized areas of the mainboard where heat is generated, thereby increasing heat dissipation efficiency. This facilitates rapid and measured heat dissipation in localized areas of the mainboard, avoids localized high temperatures, and improves overall system performance. Furthermore, positioning the second pipe section on the side of the cooling fan away from the coupling end fully utilizes the space behind the cooling fan.

[0013] In a feasible embodiment, the mainboard is located on the side of the cooling fan away from the second pipe section. In this embodiment, the mainboard and the second pipe section are located on both sides of the cooling fan, the layout structure is relatively compact, and the space utilization rate is high.

[0014] In a feasible embodiment, the hinge structure includes a core shaft, the host housing includes a C-surface facing the display assembly, the core shaft is located above the surface, and the keyboard mounting surface is located on the C-surface.

[0015] In a feasible embodiment, the angle between the display panel and the first closed surface ranges from 0.1° to 0.5°;

[0016] Alternatively / and, the minimum distance range between the circuit board assembly and the top wall of the display housing is from 0.3 mm to 0.7 mm. In this embodiment, the display panel is at an angle of 0.1° to 0.5° with the first closed surface, which does not affect the installation of other components in the display assembly while meeting the requirement of increasing the distance between the display panel and the keyboard.

[0017] In a second aspect, an embodiment of the present application further provides a display assembly of an electronic device. The electronic device includes a main body assembly and a display assembly rotatably connected. The display assembly includes:

[0018] A display housing having a first closed surface, which fits and cooperates with the main body assembly when the electronic device is in a closed state;

[0019] A display screen including a display panel and a circuit board assembly. The display panel and the display housing enclose a cavity, and the circuit board assembly is located in the cavity. The display housing includes opposite connection ends and opening / closing ends. The circuit board assembly is disposed at one end of the display screen close to the connection ends. The display panel is inclined relative to the first closed surface, and along the direction from the opening / closing ends to the connection ends, the distance between the display panel and the first closed surface increases.

[0020] Compared with the prior art where the display panel is parallel to the first closed surface, the display panel in the embodiment of the present application is inclined relative to the first closed surface, making full use of the gap size between the circuit board assembly and the display housing. On the premise of ensuring the normal operation of the circuit board assembly, the size of the circuit board assembly and the display housing in the thickness direction is minimized as much as possible, achieving the effect of increasing the distance between the display panel and the keyboard. In this way, the position of the keyboard can be lifted upward relative to the main body housing, reducing the occupation of the internal space of the main body housing, which is beneficial to optimizing the layout of other electronic components inside the main body housing, and further reducing the thickness of the main body assembly to meet the requirement of the thin and light design of the electronic device.

[0021] Moreover, by the method provided in the embodiment of the present application to reduce the thickness of the electronic device, there is no need to sink the hinge structure of the vertical laptop to one side of the main body assembly, which does not affect the layout of heat dissipation structures such as the cooling fan and heat dissipation holes, and does not block the air outlet of the cooling fan, further improving the overall performance of the laptop.

[0022] In a feasible embodiment, when the electronic device is in a closed state, the first closed surface is parallel to the keyboard mounting surface of the main body assembly.

[0023] In a feasible embodiment, the display housing includes a first housing. The first housing includes a top wall. A connecting structure is provided on one side of the top wall for connecting to the rotating shaft structure. Side walls are connected to the remaining sides of the top wall. The display screen is positioned inside the space surrounded by the side walls. The circuit board assembly is located between the display panel and the top wall. The surface of the side wall away from the top wall includes a first closed surface. In this embodiment, the first closed surface is provided on each side of the top wall except for the side connected to the rotating shaft structure. When the electronic device is in the closed state, the display assembly is supported on the host assembly through the first closed surface, avoiding vibration of the display assembly and improving the installation stability of the display assembly when in the closed state.

[0024] In a feasible embodiment, a raised surface is formed by the partial area of the surface of the side wall away from the top wall, and the raised surface is the first closed surface. This can minimize the thickness of the electronic device.

[0025] In a feasible embodiment, the top wall also has two wedge-shaped supports. The wedge-shaped supports extend from the connecting end to the opening and closing end. In the direction from the connecting end to the opening and closing end, the thickness of the wedge-shaped support gradually decreases. The display panel is supported against the wedge-shaped supports, and the two wedge-shaped supports are located on both sides of the circuit board assembly. This can improve the installation stability of the display panel.

[0026] In a feasible embodiment, the included angle range between the display panel and the first closed surface is: 0.1° to 0.5°;

[0027] Or / and, the minimum distance range between the circuit board assembly and the display housing is 0.3 mm to 0.7 mm.

[0028] In a feasible embodiment, a groove is further provided on the surface of the display housing facing the display screen. The notch of the groove faces the circuit board assembly, and the distance between the circuit board assembly and the bottom wall of the groove is within a preset range. In the embodiment of the present application, the minimum distance between the circuit board assembly and the first housing is the distance between the circuit board assembly and the bottom of the groove. This can increase the inclination angle of the display panel relative to the keyboard mounting surface, which is beneficial to increasing the distance between the display panel and the keyboard, increasing the height of the keyboard lift, further reducing the occupation of the internal space of the unit housing by the keyboard, and playing a role in reducing the overall thickness of the electronic device.

[0048] In view of the problem of reducing the thickness of the notebook computer mentioned in the background art, the inventors of the present application have conducted a large amount of research on the structure of the existing notebook computer. In terms of reducing the thickness of the notebook computer, the difficulty of reducing the thickness of the notebook computer with the rotating shaft structure above the main body component is the greatest. The notebook computer with the rotating shaft structure above the main body component is also called a vertical shaft notebook computer. For a certain model of vertical shaft notebook computer, the rotating shaft in the rotating shaft structure is basically constant, and the space it occupies is also constant. Currently, the thickness of the vertical shaft notebook computer can only be reduced by sinking the rotating shaft part to one side of the main body component. However, when the rotating shaft structure sinks to the main body component, it occupies the installation space of the heat dissipation structure and blocks the air outlet of the heat dissipation fan, thereby affecting the overall performance of the notebook computer.

[0049] Based on the above research, the inventors of the present application further explored and proposed a technical solution that can effectively reduce the thickness of the notebook computer, which is particularly significant for reducing the thickness of the vertical shaft notebook computer.

[0050] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] The electronic device provided by the embodiment of the present application can be a mobile terminal such as a notebook computer, a tablet computer, a tablet computer accessory, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a mobile phone, etc. Or, it can also be a professional shooting device such as a digital camera, a single-lens reflex camera / mirrorless camera, an action camera, a gimbal camera, a drone, etc. The specific type of the electronic device is not limited in the embodiment of the present application. For the convenience of understanding, the following takes the electronic device as a notebook computer as an example for description.

[0052] Please refer to Figures 1 to 3 , Figure 1Schematic diagram of an electronic device in an open state in an embodiment of the present application; Figure 2 is Figure 1 Schematic diagram of the electronic device shown in a closed state; Figure 3 is Figure 1 Exploded schematic diagram of the electronic device shown. The electronic device 100 provided in an embodiment of the present application includes a host component 1, a display component 2, and a rotating shaft structure 3. The host component 1 and the display component are connected by the rotating shaft structure 3. By using the rotating shaft structure 3, the opening and closing ends of the host component 1 and the display component 2 are relatively close to or away from each other, so that the electronic device 100 is in a closed state and an open state. Figure 1 In the electronic device 100, a laptop computer is taken as an example. Figure 1 It is shown that the display component 2 is the display side of the laptop computer, and the host component 1 is the keyboard side of the laptop computer, where Figure 1 is a schematic diagram of the electronic device 100 at a certain moment in the open state. Figure 2 is a schematic diagram of the electronic device 100 in the closed state.

[0053] From Figure 1 it can be seen that the host component 1 includes a host housing 11 and a keyboard 12. The host housing 11 includes a housing one 111 and a housing two 112 ( Figure 1 not shown in Figure 3 for reference and understanding). Conventionally, the housing one 111 is also called the C shell, the surface of the housing one 111 facing the display screen 22 (the keyboard mounting surface 10) is called the C surface, the housing two 112 is called the D shell, and the bottom surface of the housing two 112 facing away from the housing one 111 is called the D surface. The housing one 111 and the housing two 112 are assembled to form an inner cavity for installing electronic devices in the host component 1.

[0054] Please refer to Figure 3It is understood that the host component 1 further includes components such as a main board 13, a cooling fan 15, a heat dissipation module 16, and a battery 17. Electronic devices such as the main board 13, the cooling fan 15, the heat dissipation module 16, and the battery 17 are located in the inner cavity formed by the housing one 111 and the housing two 112. Among them, the main board 13 in the host component 1 is the main board of the electronic device 100, which is the core component of the electronic device 100 and is the "overpass" for various hardware in the electronic device 100 to transmit data and information. It integrates various hardware such as a graphics card, memory, and a central processing unit (CPU), and organically combines the various electronic devices of the electronic device 100 to jointly maintain the normal operation of the electronic device 100. The air outlet of the cooling fan 15 faces the main board 13 to dissipate heat from the main board 13. The number of cooling fans 15 can be one or two. The housing one 111 also has a keyboard mounting surface 10, and keyboard mounting holes 11a are provided on the keyboard mounting surface 10. The housing one 111 is also provided with a touchpad mounting hole 11b for mounting the touchpad 14, and the touchpad 14 has at least the function of a mouse. In the embodiment of the present application, the housing one 111 includes a housing main body 111-1 and a bent side wall 111-2. The bent side wall 111-2 is connected to the circumference of the housing main body 111-1, and the bent side wall 111-2 is fixedly connected to the housing two 112, and the bent side wall 111-2 extends towards the housing two 112. The above-mentioned touchpad mounting hole 11b and keyboard mounting surface 10 are both provided on the housing main body 111-1, and a first heat dissipation hole 111a can be further provided on the bent side wall 111-2. The housing two 112 may include a bottom plate 112-1 and side plates 112-2 connected to the circumference of the bottom plate. The side plates 112-2 extend upward at a predetermined angle with respect to the bottom plate 112-1. The side plates 112-2 are fixedly connected to the bent side wall 111-2, and a second heat dissipation hole 112b may be further provided at a position where the side plates 112-2 are close to the cooling fan 15 and the heat dissipation module 16.

[0055] In the embodiment of the present application, the specific structures of the housing one 111 and the housing two 112 are not limited as long as they meet the usage requirements.

[0056] In the embodiment of the present application, the rotating shaft structure 3 includes a core shaft 31. The core shaft 31 is located on the surface of the housing one 111 facing the display screen 22, that is, the core shaft 31 is located above the C surface. There is a predetermined gap between the core shaft 31 and the C surface, and the predetermined gap can be 0.8 mm. There is a gap between the core shaft 31 and the C surface, which can prevent the rotating shaft structure 3 from wearing the C surface.

[0057] The keyboard mounting surface 10 is located on the surface (C surface) of the housing one 111 facing the display screen 22. That is to say, this surface (C surface) includes the keyboard mounting surface 10. Among them, this surface can be a plane, and of course, it can also be a non-plane, and the keyboard mounting surface 10 can sink relative to other positions on this surface.

[0058] Please refer to again Figure 3 , Figure 3 is Figure 1 an exploded view of the electronic device 100 shown, in which the display assembly 2 includes a display screen 22 and a display housing 21. The display screen 22 is assembled on the display housing 21. As can be seen from Figure 3 , the display housing 21 includes two parts: a first housing 211 and a second housing 212. Usually, the first housing 211 is also called the A shell, and the second housing 212 is also called the B shell. The display screen 22 is installed between the first housing 211 and the second housing 212. Of course, it is not excluded that the display housing 21 is of an integrated form and the display screen 22 is installed on the display housing 21.

[0059] In the embodiments of the present application, the display screen 22 is used to display images, videos, etc. The display screen 22 includes a display panel 221 and a circuit board assembly 222. The display panel 221 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Miniled, a MicroLed, a Micro-oLed, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the electronic device 100 may include one or N display screens 22, where N is a positive integer greater than 1.

[0060] In the embodiments of the present application, the circuit board assembly 222 in the display screen 22 is a printed circuit board (PCB) equipped with electronic devices, also known as a PCBA (Printed Circuit Board Assembly). The circuit board assembly 222 is used to control the display function of the display panel 221. The circuit board assembly 222 is usually located on the back side of the display panel 221 and close to one end of the rotating shaft structure 3. In the embodiments of the present application, the side of the display panel 221 where the display screen is located is defined as the front side, and correspondingly, the side facing away from the display screen is defined as the back side. For the sake of simplicity in describing the technical solution, in this article, the end of the display housing 21 close to the rotating shaft structure 3 is defined as the connecting end, and the end opposite to the connecting end and capable of rotating relative to the connecting end is defined as the opening and closing end. In the embodiments of the present application, the circuit board assembly 222 is disposed at one end of the display screen 22 close to the connecting end.

[0061] Please refer to Figure 4-1 , Figure 4-2 , Figure 5 and Figure 6. In the embodiments of the present application, when the electronic device 100 is in a closed state, theoretically, the display housing 21 and the host housing 11 can partially fit together. That is to say, the display housing 21 has a first closing surface 2110, and the host housing 11 has a second closing surface 1111. Theoretically, when the electronic device 100 is in a closed state, the first closing surface 2110 and the second closing surface 1111 are parallel and fit together. Of course, in some embodiments, due to installation limitations, assembly errors, machining errors, etc., the first closing surface 2110 and the second closing surface 1111 are approximately parallel, and there is a non-fitting situation. As long as it is within the allowable error range, it is within the range of the fitting cooperation between the first closing surface 2110 and the second closing surface 1111 described in the embodiments of the present application.

[0062] In the embodiments of the present application, the first closing surface 2110 is provided on the first housing 211. Specifically, the first housing 211 includes a top wall 211-1. A connecting structure is provided on one side of the top wall 211-1 for connecting to the rotating shaft structure 3. The connecting structure can be determined according to the specific form of the rotating shaft structure 3. On the sides of the top wall other than the side where the connecting structure is provided, side walls 211-2 are provided. The display screen 22 is positioned in the space surrounded by the side walls 211-2 and the top wall 211-1. Taking a laptop computer as an example, the top wall 211-1 is a rectangular plate, and a connecting structure is provided on one side edge of the rectangular plate, and side walls 211-2 are provided on the other three side edges. In the embodiments of the present application, the surface of the side wall 211-2 away from the top wall 211-1 includes the first closing surface 2110. The first closing surface 2110 can be a part of this surface or the entire surface. In the present application, it is shown that the first closing surface 2110 is a part of this surface, which is beneficial to reducing the weight of the electronic device 100. In this embodiment, the first closing surface 2110 is provided on each side of the top wall 211-1 except the side connected to the rotating shaft structure 3. When the electronic device 100 is in a closed state, the display assembly 2 is supported on the host assembly 1 through the first closing surface 2110, avoiding vibration of the display assembly and improving the installation stability of the display assembly when it is in a closed state.

[0063] In the embodiments of the present application, a raised surface is formed by the partial region of the surface of the side wall away from the top wall. The raised surface fits and cooperates with the second closing surface 1111 on the housing 111 of the host assembly 1. In some embodiments, the second closing surface 1111 and the keyboard mounting surface 10 can be coplanar. Of course, the second closing surface 1111 and the keyboard mounting surface 10 can also be non-coplanar and parallel to each other.

[0064] Please refer to Figure 7 and Figure 8 , Figure 7 For Figure 5Simplified diagram of the structure shown Figure 8 is Figure 7 an enlarged schematic view of the position E in [reference document]. The dashed line S in the figure represents the original position of the lower surface of the display panel 221 before rotation. For a schematic diagram of the electronic device in the closed state in the prior art, please further refer to Figure 9 . In the embodiment of the present application, the display panel 221 is inclined relative to the first closed surface 2110, and along the direction from the opening and closing end to the connecting end, the distance between the display panel 221 and the first closed surface 2110 shows an increasing trend. That is to say, the closer to the connecting end, the greater the distance between the display panel 221 and the first closed surface 2110. That is, when the electronic device 100 is in the closed state, along the direction from the opening and closing end to the connecting end, the distance between the display panel 221 and the keyboard mounting surface 10 shows an increasing trend. The closer to the connecting end, the greater the distance between the display panel 221 and the keyboard mounting surface 10. The display panel 221 and the keyboard mounting surface 10 are arranged at a predetermined angle, and the range of this angle can be determined according to the minimum distance between the circuit board assembly and the top wall. In one embodiment, the minimum distance m between the circuit board assembly and the top wall can range from 0.3 mm to 0.7 mm, such as 0.3 mm, 0.4 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, etc. Those skilled in the art should understand that the minimum distance between the circuit board assembly 222 and the top wall 211-1 can be any value within the above numerical range. The range of this angle is approximately from 0.1° to 0.5°, such as 0.1°, 0.2°, 0.3°, 0.4° or 0.5°, etc. The above numerical ranges in the embodiments of the present application are only optional embodiments. Of course, in other embodiments, the numerical ranges can also be other values, as long as the function of increasing the distance between the display panel 221 and the system components is achieved by the inclined setting of the display panel 221

[0065] Please refer to Figure 9 and Figure 10 for understanding Figure 9 is a schematic diagram of the structure of the display panel 221 before rotation; before the display panel 221 rotates, the distance between the display panel 221 and the keyboard 12 is m1. A gap is provided between the display panel 221 and the keyboard 12 mainly to avoid contact and wear between the display panel 221 and the keyboard 12. Please refer to Figure 10 , Figure 10Schematic diagram of the electronic device 100 when the display panel 221 rotates but the keyboard 12 has not been lifted yet. When the display panel 221 rotates by a predetermined angle around the side edge P near the opening / closing end side, when the minimum distance m between the circuit board assembly 222 and the top wall 211-1 meets the design requirements, the distance between the display panel 221 and the keyboard 12 increases significantly. At this time, the minimum distance m2 between them is the distance m2 between the first end 124 of the keyboard 12 near the opening / closing end side and the display panel 221, and the distance between the second end 123 of the keyboard 12 near the connection end side and the display panel 221 is significantly greater than m2. Obviously, the increased minimum distance between the display panel 221 and the keyboard is m2 - m1. In this way, on the premise of meeting the design requirement gap m between the display panel 221 and the keyboard 12, the installation position of the keyboard 12 can be moved a distance of m2 - m1 relative to the main body housing 11 towards the display screen 22 side, and the internal space occupied by the keyboard in the main body assembly 1 is reduced.

[0066] Compared with the prior art where the display panel 221 is arranged parallel to the first closing surface 2110, in the embodiment of the present application, the display panel 221 is inclined relative to the first closing surface 2110, making full use of the gap size between the circuit board assembly 222 and the display housing 21. On the premise of ensuring the normal operation of the circuit board assembly 222, the size of the circuit board assembly 222 and the display housing 21 in the thickness direction is minimized as much as possible, achieving the effect of increasing the distance between the display panel 221 and the keyboard. In this way, the position of the keyboard can be lifted upwards relative to the main body housing 11, reducing the occupation of the internal space of the main body housing 11, which is beneficial to optimizing the layout of other electronic devices inside the main body housing 11, and further reducing the thickness of the main body assembly 1 to meet the thin and light design requirements of the electronic device 100.

[0067] Moreover, by the method provided in the embodiment of the present application to reduce the thickness of the electronic device 100, there is no need to sink the rotating shaft structure of the vertical laptop computer to one side of the main body assembly 1, which does not affect the arrangement of heat dissipation structures such as the heat dissipation fan and heat dissipation holes, and does not block the air outlet of the heat dissipation fan, further improving the overall performance of the laptop computer.

[0068] In the embodiment of the present application, the minimum distance range between the circuit board assembly 222 and the display housing 21 is 0.5 mm to 0.7 mm. That is to say, after the display panel 221 is inclined, the minimum distance between the circuit board assembly 222 and the display housing 21 can be between 0.5 mm and 0.7 mm to ensure the reliable operation of the circuit board assembly 222.

[0069] In the embodiment of the present application, the included angle range between the display panel 221 and the first closing surface 2110 is 0.1° to 0.5°, and the included angle between them can be any value within the range of 0.1° to 0.5°, such as 0.1°, 0.2°, 0.3°, 0.4° or 0.5°.

[0070] In the embodiment of the present application, when the display panel 221 is an LCD panel and the included angle between the display panel 221 and the first closed surface 2110 is 0.2°, the minimum distance between the circuit board assembly 222 and the display housing 21 is 0.6 mm. The gap between the keyboard and the display panel 221 changes from the original equal gap of 0.6 mm to a trapezoidal gap of 0.97 mm to 1.5 mm. At this time, on the premise of maintaining the minimum gap of 0.6 mm between the keyboard and the display panel 221, the keyboard can be lifted 0.37 mm towards the display panel 221 side. In this way, the thickness of the host component 1 can be reduced by 0.37 mm, and further the overall thickness of the electronic device 100 can be reduced by 0.37 mm.

[0071] Generally speaking, after the display panel 221 is arranged at an included angle with the keyboard mounting surface (the first closed surface 2110) in the embodiment of the present application, for a display panel with a relatively large thickness such as an LCD panel, the reduction range of the thickness dimension of the electronic device is about 0.5 mm. If the display panel is an OLED, because the display screen is thinner and the gap space between the circuit board assembly 222 and the display housing is more abundant, the inclination angle of the display panel 221 will be larger, and the reduction dimension of the thickness of the electronic device 100 will be larger.

[0072] The reduced dimension of the overall thickness of the electronic device 100 is related to the type of the display panel 221, the included angle between the display panel 221 and the first closed surface 2110, and the minimum distance between the circuit board assembly 222 and the display housing 21. The above parameters can be set according to specific products to achieve the reduction of the overall thickness of the electronic device 100.

[0073] In particular, when the technical solution in the embodiment of the present application is applied to the case where the display panel 221 is an OLED, the reduction degree of the thickness of the electronic device 100 is very significant.

[0074] In addition, after the keyboard is lifted, the installation of the electronic components inside the unit housing 11 can be optimized. For example, the cooling fan 15 can be completely or partially placed directly below the keyboard 12, that is, at least part or all of the projection of the cooling fan 15 is located inside the projection of the keyboard 12. In this way, a cooling fan 15 with a larger volume and higher power can be used to improve the heat dissipation efficiency of the main board 13. Of course, the number of cooling fans 15 can also be increased to improve the heat dissipation efficiency of the main board 13.

[0075] Alternatively, the electronic device 100 can add a heat dissipation module 16 or increase the volume of the heat dissipation module 61 to further improve the additional heat dissipation for a local area of the main board with a relatively large heat generation, improve the heat dissipation efficiency of the main board 13, facilitate the rapid dissipation of the heat in the local area of the main board, and thus enhance the overall working performance of the machine. In the embodiment of the present application, the heat dissipation module includes a heat dissipation pipe 161 with a medium flowing inside. The heat dissipation pipe 161 includes a first pipe section and a second pipe section. The first pipe section and the second pipe section are connected through the flowing medium. The first pipe section is stacked with the main board 13, and the second pipe section is located on one side of the heat dissipation fan 15 away from the opening and closing end. A plurality of heat dissipation fins 162 can be provided on the second pipe section to improve the heat dissipation efficiency.

[0076] Among them, the main board and the second pipe section can be located on both sides of the heat dissipation fan, that is, the main board is located on the side of the heat dissipation fan away from the second pipe section. In this embodiment, the structure of the electronic device 100 is relatively compact. A plurality of through holes can be opened on the side wall of the main body housing 11 for air intake or heat dissipation.

[0077] In order to minimize the thickness of the electronic device 100 as much as possible, the embodiment of the present application can also be set as follows.

[0078] Please refer to Figures 11 to 12 , in the embodiment of the present application, a groove 2112 is provided on the top wall of the first housing. That is to say, a groove 2112 is also provided on the surface of the display housing 21 facing the display screen 22. The notch of the groove 2112 faces the circuit board assembly 222, and the distance between the circuit board assembly 222 and the bottom wall 21121 of the groove 2112 is within a preset range. The preset range can be about 0.6 mm as described above.

[0079] In this embodiment, the size of the groove 2112 is determined according to the partial structure of the circuit board assembly 222 close to the first housing. The circuit board assembly 222 can be partially located inside the groove 2112. Of course, the circuit board assembly 222 can also be completely located outside the groove 2112. The depth of the groove 2112 can be determined according to the specific electronic device 100 as long as the use strength of the first housing at the position where the groove 2112 is provided can be ensured. In the embodiment of the present application, the minimum distance between the circuit board assembly 222 and the first housing is the distance between the circuit board assembly 222 and the bottom of the groove 2112. In this way, the inclination angle of the display panel 221 relative to the keyboard mounting surface 10 (the first closing surface 2110) can be increased, which is beneficial to increasing the distance between the display panel 221 and the keyboard, increasing the height of the keyboard lift, further reducing the occupation of the internal space of the unit housing by the keyboard, and playing a role in reducing the overall thickness of the electronic device 100.

[0080] In the embodiments of the present application, the top wall further has a wedge-shaped support body, which extends from the connecting end to the opening and closing end. In the direction from the connecting end to the opening and closing end, the thickness of the wedge-shaped support body gradually decreases, and the display panel 221 is abutted and supported on the wedge-shaped support body. The number of the wedge-shaped support bodies is two, and the two wedge-shaped support bodies are located on both sides of the circuit board assembly 222. The wedge-shaped support body can play a role in stably supporting the display panel 221 and improve the reliability of the fixation of the display panel 221 to the display housing 21.

[0081] Please refer to Figure 11 , in order to improve the heat dissipation performance of the electronic device 100, a foot pad 1121 can also be provided at a partial position at the bottom of the housing two 112. The electronic device 100 is supported on the desktop through the foot pad 1121, which is beneficial to the heat dissipation at the bottom of the electronic device 100.
