Description

Technical Field

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

[0002] Existing laptop computers have a fan and a heating element installed within their main housing. The main housing also has a heat inlet and a heat outlet. The fan draws air from the outside environment into the main housing through the heat inlet. The air then flows through the heating element, removing heat, and exits through the heat outlet. However, due to the lack of a barrier between the heat inlet and the heat outlet, hot air discharged from the heat outlet can flow into the heat inlet, affecting the laptop's cooling performance. Summary of the Invention

[0003] The present application provides a laptop computer to solve the technical problem that hot air discharged from a heat dissipation outlet flows toward a heat dissipation inlet, thereby affecting the heat dissipation effect of the laptop computer.

[0004] The technical solution is as follows:

[0005] A first aspect of the present application provides a laptop computer, comprising:

[0006] Display screen;

[0007] The main unit is rotatably connected to the display unit, the bottom of the main unit is provided with an air inlet, and the end of the main unit close to the rotational connection with the display unit is provided with an air outlet;

[0008] A damper mechanism, the damper mechanism including a baffle for opening or closing the air inlet;

[0009] The baffle is supported on the main unit, the air inlet includes a first side surface and a second side surface relative to each other, the second side surface is closer to the air outlet relative to the first side surface, and the baffle can extend out of the main unit and rotate in a direction away from the second side surface.

[0010] In the present application, the laptop computer is provided with a damper mechanism, so that when air needs to be taken in from the air inlet at the bottom of the main body, the baffle of the damper mechanism can be controlled to open the air inlet. The baffle in the open state can prevent the hot air discharged from the air outlet from flowing back to the air inlet, thereby improving the heat dissipation efficiency of the laptop computer. When air does not need to be taken in from the air inlet, the baffle of the damper mechanism can be controlled to close the air inlet, thereby preventing dust, hair and other debris from entering the interior of the laptop without affecting the aesthetics of the laptop computer.

[0011] In some implementations, the damper mechanism includes a transmission structure, the display screen portion includes a pivot assembly for rotationally connecting to the host portion, the transmission structure connects the pivot assembly and the baffle, the baffle is rotationally connected to the host portion, and the display screen portion can drive the baffle to move when it is opened relative to the host portion.

[0012] In this implementation, a transmission structure is provided to connect the baffle and the pivot assembly, thereby facilitating the connection between the baffle and the pivot assembly of the display screen portion in terms of spatial position, thereby facilitating the simplification of the structure of the transmission structure.

[0013] In some implementations, the transmission structure includes a sliding portion and a connecting portion, the connecting portion connects the sliding portion and the baffle, the sliding portion is movably connected to the pivot assembly, and when the display screen portion rotates, the pivot assembly can drive the sliding portion to move along the length direction of the pivot assembly or the radial direction of the pivot body.

[0014] In this implementation, the sliding portion is connected to the pivot assembly to convert the rotation into linear movement, and the connecting portion drives the baffle to open or close the air outlet through the reciprocating movement of the connecting portion along the linear direction.

[0015] In some implementations, a slide groove is provided on the circumferential side of the pivot assembly, one end of the sliding portion is inserted into the slide groove, and the slide groove includes at least an oblique groove portion, and the length of the oblique groove portion runs along the axial direction of the pivot assembly and along the circumferential direction of the pivot assembly.

[0016] In this implementation, by setting one end of the sliding part to be inserted into the inclined groove part on the circumferential side of the pivot assembly, the sliding part can be driven to move relative to the pivot assembly along the axial direction of the pivot assembly when the display screen part is rotated, and the transmission structure and the pivot assembly are coordinated.

[0017] In some implementations, the slide groove also includes a straight groove portion, which is connected to one end of the oblique groove portion, and the extension direction of the straight groove portion is along the circumferential direction of the pivot assembly; wherein, when the angle of the display screen portion is opened is not greater than the set angle, one end of the sliding portion is inserted into the oblique groove portion, and when the angle of the display screen portion is opened is greater than the set angle, one end of the sliding portion is inserted into the straight groove portion.

[0018] In this implementation, the sliding portion is provided to include not only an oblique groove portion but also a straight groove portion, so that even if the angle of the display screen portion is different due to different user habits, the baffle opening angle can be made the same. At the same time, when the baffle is subjected to an external force in the direction of closing the air inlet, the display screen portion will not rotate, that is, the movement can only be transmitted from the display screen side to the baffle side, otherwise it will get stuck.

[0019] In some implementations, the set angle ranges from 60° to 90°.

[0020] Typically, when using a laptop computer, the display screen is opened at an angle greater than 90° so that the user can easily view the content displayed on the display screen. Therefore, in the embodiment of the present application, the set angle is set in the range of 60° to 90°, so that even if the angle of the display screen varies due to different user habits, the bezel can still be opened at the same angle.

[0021] In some implementations, a sliding sleeve is provided on one end of the sliding portion extending into the sliding groove to reduce friction, so that the sliding portion can slide in the sliding groove.

[0022] In some implementations, the connecting part includes a fixed seat, a slider and a connecting rod. The fixed seat is fixed in the main body part. The slider is movably connected to the fixed seat and the fixed seat guides the movement of the slider. The slider is connected to the sliding part. The connecting rod connects the slider and the baffle and the connecting rod is rotatably connected to the slider and the baffle. When the sliding part moves along the length direction of the pivot assembly, the connecting rod can drive the slider to move on the fixed seat, thereby causing the slider to drive the connecting rod to move.

[0023] In this implementation, the structure of the damper mechanism can be simplified by providing the connecting portion including a fixing seat, a sliding block and a connecting rod.

[0024] In some implementations, a first protrusion is formed on the sliding portion, a slider groove is provided on the slider, and the first protrusion is inserted into the slider groove; the slider groove extends in a direction parallel to the axis of the pivot assembly and extends in a direction from close to the baffle to away from the baffle.

[0025] In this implementation, by setting a first protrusion on the sliding part to be inserted into the slider groove on the slider, the sliding part can drive the slider to move from the baffle to the baffle when moving along the length direction of the pivot assembly, and the connection structure between the sliding part and the slider is simple.

[0026] In some implementations, a first guide groove is provided on the fixed seat, and the slider is provided in the first guide groove. The opposite ends of the slider are fitted with the groove walls on the corresponding sides of the first guide groove along the axial direction parallel to the pivot assembly, and the length of the first guide groove along the axial direction perpendicular to the pivot assembly is greater than the length of the slider.

[0027] In this implementation, by providing the first guide groove on the fixing seat and the slider in the first guide groove, not only the fixing seat can guide the movement of the slider, but also the connection structure between the two is simple.

[0028] In some implementations, a second protrusion is provided on the sliding portion, a second guide groove is provided on the fixing seat, the second protrusion is inserted into the second guide groove, and the length extension direction of the second guide groove is parallel to the axial direction of the pivot assembly.

[0029] In this implementation, by providing a second protrusion on the slider portion and inserting the second protrusion into the second guide groove on the fixing seat, the limiting sliding portion can stably move along a length direction parallel to the pivot assembly.

[0030] In some implementations, there are two transmission structures, which are spaced apart along the length of the pivot assembly, and the connection position between each transmission structure and the baffle is close to the end of the corresponding side of the baffle.

[0031] In this implementation, the connection position between each transmission structure and the baffle is arranged close to the end of the corresponding side of the baffle, so that the baffle is evenly stressed.

[0032] In some implementations, the first side surface is an arcuate concave surface, one end of the baffle extends toward the first side surface, and the end of the baffle extending toward the first side surface is an arcuate convex surface matching the arcuate concave surface.

[0033] In this implementation, the first side surface of the air inlet is set as an arc concave surface and an arc convex surface is set on the baffle to match the arc concave surface, so that the baffle can be set in the air inlet and can be rotated relative to the bottom shell of the main unit.

[0034] In some implementations, one or more baffle grooves are provided on the inner side surface of the baffle, the baffle grooves being close to one side of the arc convex surface and being open to the arc convex surface, and each baffle groove is provided with a first mating protrusion;

[0035] The main unit includes a bottom shell with an air inlet, a bottom shell groove is provided on the inner side surface of the bottom shell, the bottom shell groove is close to the arc concave surface and is connected to the arc concave surface, a limiting member is provided on the bottom surface of the bottom shell groove, an arc groove surface is provided on the limiting member, a first mating protrusion is inserted into the arc groove surface and the first mating protrusion is rotatably connected to the limiting member.

[0036] In some implementations, a second mating protrusion is further provided in each baffle groove, and the second mating protrusions extend toward the corresponding bottom shell groove.

[0037] In this implementation, the baffle is stably rotatably connected to the bottom shell by arranging the first matching protrusions to extend toward the corresponding bottom shell slots and the second matching protrusions to cooperate with the limiting member.

[0038] In some implementations, the host unit includes a main housing and a cooling fan. The cooling fan is disposed inside the main housing. An air inlet is disposed at the bottom of the main housing. The air inlet is located between the cooling fan and a side of the main housing where the display screen unit is disposed. The air inlet is close to the cooling fan.

[0039] In this implementation, the air inlet is arranged close to the cooling fan so that when the cooling fan is working, external air enters the laptop through the air inlet.

[0040] In some implementations, the outer bottom surface of the main unit includes a first area and a second area, the first area is close to the side where the main unit is connected to the display screen unit, and the second area is away from the side where the main unit is connected to the display screen unit, and the baffle is located in the first area, wherein: both the first area and the second area are provided with foot pads, and the two foot pads in the first area are located on both sides of the baffle, or, only the first area is provided with foot pads, and the two foot pads in the first area are located on both sides of the baffle.

[0041] In this implementation, the laptop computer is mainly supported on the support surface by the foot pad, so that the laptop computer is stably supported on the support surface.

[0042] In some implementations, only the second area is provided with a foot pad, and the baffle in the open state can support the host part; or, no foot pad is provided on the first area and the second area, and the baffle in the open state can support the host part.

[0043] In this implementation, the baffle in the open state can not only prevent the hot air discharged from the air outlet from flowing back to the air inlet, but also serve as a foot pad to support the laptop computer, thereby reducing or even eliminating the foot pad, thereby simplifying the structure of the laptop computer.

[0093] To make the purpose, technical solutions and advantages of this application more clear, the following will further describe the implementation methods of this application in detail with reference to the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and are intended to be used to explain this application, and should not be understood as limiting this application.

[0094] In the description of this application, it should be understood that the terms "length", "width", "thickness", "top", "bottom", "inside", "outside", "up", "down", "left", "right", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.

[0095] To facilitate the clear description of the technical solutions of this application, the words "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that the words "first" and "second" do not limit the quantity or order of execution, and the words "first" and "second" do not necessarily mean different.

[0096] In this application, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0097] In this application, "and / or" is simply a way to describe the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0098] It should be noted that, in this application, words such as "in one embodiment," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in one embodiment," "exemplarily," or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a concrete manner.

[0099] Before explaining the laptop computer 100 provided in the embodiment of the present application in detail, the existing related technologies and scenarios are first explained.

[0100] See Figure 1-Figure 3 , Figure 1 FIG1 is a structural diagram of an existing related notebook computer 100 in an open state. Figure 2 FIG1 is a bottom view of a notebook computer 100 in the prior art. Figure 3 FIG. 1 is another bottom view of the notebook computer 100 .

[0101] See Figure 1 The notebook computer 100 generally includes a display screen portion 10 and a main body portion 20, wherein the display screen portion 10 is rotatably connected to one end of the main body portion 20. The main body portion 20 includes a main body housing 21 ', see Figure 1A heat dissipation inlet 211' is provided at the bottom of the main housing 21', and a heat dissipation outlet 212' is provided at one end where the main unit 20 and the display unit 10 are pivotally connected. A fan and a heating element are provided within the main housing 21' of the laptop computer 100. The fan drives air from the external environment into the main housing 21' through the heat dissipation inlet 211'. The air then flows through the heating element, removing heat, and exits through the heat dissipation outlet 212'.

[0102] See Figure 1 The bottom of the host housing 21' is also protruding with a foot pad 30. When the laptop computer 100 is placed on the desktop, the foot pad 30 raises the laptop computer 100 so that there is a certain distance between the laptop computer 100 and the desktop to prevent the heat dissipation inlet 211' from being blocked, thereby ensuring that air in the external environment can flow into the heat dissipation inlet 211'.

[0103] See Figure 2 and Figure 3 The heat dissipation inlet 211' on the host shell 21' is usually in a grid shape, and the gaps in the grid are relatively small, which can prevent some dust, hair and other debris from entering the interior of the laptop computer 100. At the same time, it can also prevent small insects from entering the interior of the laptop computer 100 to a certain extent, avoiding damage to the interior of the laptop computer 100.

[0104] See Figure 2 , schematically shows that four foot pads 30 are distributed at the bottom of the host housing 21 ′, and the four foot pads 30 are respectively located near the four corners of the bottom of the host housing 21 ′. Figure 2 The solid arrows indicate the airflow flowing in from the heat dissipation inlet 211', and the dotted arrows indicate the airflow being discharged from the heat dissipation outlet 212'. The heat dissipation inlet 211' and the heat dissipation outlet 212' are relatively close to each other and since there is no obstruction between the heat dissipation inlet 211' and the heat dissipation outlet 212', the hot air discharged from the heat dissipation outlet 212' can easily flow back to the heat dissipation inlet 211' at the bottom of the main body shell 21' under the action of the fan in the main body shell 21', thereby allowing the hot air to re-enter the interior of the laptop computer 100, affecting the heat dissipation effect of the laptop computer 100. The electronic components in the laptop computer 100 are kept in a high temperature state for a long time and are easily damaged, thereby affecting the service life of the laptop computer 100.

[0105] See Figure 3, schematically showing the foot pads 30 located at the heat inlet 211' and the heat outlet 212'. The length of the foot pad 30 is not less than the length of the heat inlet 211'. In other words, it can be understood that a sufficiently long foot pad 30 can be provided so that the foot pad 30 can prevent the hot air discharged from the heat outlet 212' from flowing back toward the heat inlet 211'. However, if the foot pad 30 is too long, there will be some problems. For example, it will affect the overall appearance of the laptop computer 100. The foot pad 30 is fixed to the host housing 21' by glue. The large contact area of ​​the foot pad 30 is prone to debonding after long-term stress. Moreover, an overly long foot pad 30 also increases the difficulty of assembly.

[0106] Based on the above problems, an embodiment of the present application provides a laptop computer 100, which adopts a damper mechanism 40 set at the air inlet 218 at the bottom of the main body 20. When air needs to be taken in from the air inlet 218, the damper mechanism 40 can open the air inlet 218, and when the damper mechanism 40 is in the open state, it can prevent the hot air discharged from the air outlet 219 from flowing back to the air inlet 218. When air does not need to be taken in from the air inlet 218, the damper mechanism 40 can close the air inlet 218, which can prevent dust, hair and other debris from entering the interior of the laptop computer 100 without affecting the aesthetics of the laptop computer 100.

[0107] The laptop computer 100 provided in the embodiment of the present application is further described below in conjunction with the accompanying drawings.

[0108] See Figure 4-11 , Figure 4 This is a structural diagram of the display screen portion 10 of the notebook computer 100 provided in an embodiment of the present application in a closed state. Figure 5 for Figure 4 A partial enlarged view of point A in the middle. Figure 6 This is a structural diagram of the display screen portion 10 of the notebook computer 100 provided in an embodiment of the present application in an open state. Figure 7 for Figure 6 A partial enlarged view of point B in the middle; Figure 8 This is an exploded diagram of a laptop computer 100 provided in an embodiment of the present application. Figure 9 This is a schematic diagram of the structure of the main unit 20 and the damper mechanism 40 provided in an embodiment of the present application (the baffle 41 is not shown). Figure 10 This is a top view of the cooling fan 22 provided in the embodiment of the present application, which is arranged on the bottom shell 212. Figure 11 A schematic diagram of a laptop computer 100 provided in an embodiment of the present application when viewed from above Figure 1 .

[0109] For ease of description, see Figure 4In the embodiment of the present application, the length direction of the laptop computer 100 is defined as the X-axis direction, the width direction of the laptop computer 100 is defined as the Y-axis direction, and the thickness direction of the laptop computer 100 is defined as the Z-axis direction, wherein the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0110] It is worth noting that the qualifiers of positional relationships such as parallel and / or perpendicular mentioned in this embodiment are all based on the current state of the art, rather than being absolute and strict definitions in a mathematical sense. A small amount of deviation is allowed, and both approximately parallel and approximately perpendicular are acceptable. In addition, this embodiment uses directional terms such as "top", "bottom", "left", "right", "front" and "back" to describe the laptop computer 100. The directions are mainly based on the position of the laptop computer 100 relative to the attached computer. Figure 4 The display directions are explained in the figure, with the positive direction of the X axis being "right", the negative direction of the X axis being "left", the positive direction of the Y axis being "front", the negative direction of the Y axis being "back", the direction facing away from the positive direction of the Z axis being "top", and the direction facing the negative direction of the Z axis being "bottom".

[0111] See Figure 4 The laptop computer 100 provided in the embodiment of the present application includes a display portion 10 and a host portion 20. The display portion 10 is rotatably connected to the host portion 20. The display portion 10 is used to display images and other information, and the host portion 20 is mainly used to process information and data.

[0112] The main unit 20 includes a main housing 21, a cooling fan 22 disposed inside the main housing 21, and heating components such as a processor (Central Processing Unit, CPU), and a battery. Figure 6 The main housing 21 may include a top housing 211 and a bottom housing 212. The top housing 211 covers the bottom housing 212, and a keyboard structure is disposed on the top housing 211. The top housing 211 and the bottom housing 212 together define a housing cavity for accommodating components such as the cooling fan 22 and heating elements. In one example, the main housing 21 may be made of a metal such as aluminum or carbon steel, which provides the main housing 21 with high strength and good structural stability.

[0113] See Figure 6 The display screen portion 10 includes a display screen assembly 11 and a display housing 12 . The display screen assembly 11 is disposed on the display housing 12 and is used to display images.

[0114] See Figure 4 and Figure 6The display screen 10 is located at one end of the main unit 20, and the display screen 10 is rotatably connected to the main unit 20. The angle between the display screen 10 and the main unit 20 can be adjusted by rotating the display screen 10 and the main unit 20, so that the display screen 10 can be adjusted to a position that is convenient for the user to observe. Figure 4 , indicating that the display screen portion 10 is covered on the host portion 20, and the user cannot use the display screen portion 10 to view images; see Figure 4 , when the display portion 10 moves along Figure 4 When rotating in the direction indicated by the middle arrow a, the angle between the display screen portion 10 and the host portion 20 gradually increases, and the user can rotate the display screen portion 10 to a suitable angle position to view the image information displayed on the display screen portion 10.

[0115] In one example, see Figure 8 The display screen portion 10 further includes a pivot assembly 13, which is disposed at one end of the display housing 12. The pivot assembly 13 includes two connecting shafts 131, which are respectively inserted into corresponding shaft seats 23 on the host portion 20 to achieve a rotational connection between the display screen portion 10 and the host portion 20. It is worth noting that in other examples, the host portion 20 may be provided with two connecting shafts 131 and the shaft seat 23 may be provided on the display screen portion 10, and the two connecting shafts 131 on the host portion 20 may be respectively inserted into corresponding shaft seats 23 on the display screen portion 10 to achieve a rotational connection between the display screen portion 10 and the host portion 20.

[0116] In one example, see Figure 8 The main unit 20 includes a rear end surface 213, which is the end of the main unit 20 away from the direction indicated by the Y-axis arrow. The middle area of ​​the rear end surface 213 is provided with an avoidance groove 214, which is arranged along the thickness direction of the main unit 20. Figure 8 In the Z-axis direction, the avoidance groove 214 is opened to the upper top surface 215 and the lower bottom surface 216 of the main body 20, and the avoidance groove 214 is opened along the length direction. Figure 8 In the X-axis direction, the two ends of the avoidance groove 214 are the protruding ends 217 of the main body 20. Figure 4 The pivot assembly 13 is disposed in the avoidance groove 214, and the two connecting shafts 131 of the pivot assembly 13 are respectively inserted into the corresponding protruding ends 217. It is worth noting that in other alternative examples, axle seats 23 can be provided on the upper top surface 215 of the main unit 20 along the thickness direction, with the two axle seats 23 close to the rear end surface 213 of the main unit 20, and the two connecting shafts 131 on the display unit 10 are respectively inserted into the two axle seats 23 on the upper top surface 215 of the main unit 20.

[0117] In the examples of this application, please see Figure 7The bottom of the main unit 20, namely the bottom shell 212, is provided with an air inlet 218, see Figure 5 An air outlet 219 is provided on the rear end surface 213 of the main unit 20. When the cooling fan 22 is in operation, the cooling fan 22 drives air from the external environment into the main unit housing 21 from the air inlet 218. The air flows through the heating element, takes away heat, and flows out from the air outlet 219.

[0118] The notebook computer 100 provided in the embodiment of the present application further includes a damper mechanism 40, which includes a baffle 41 for opening or closing the air inlet 218. Figure 5 , indicating that the baffle 41 is in a state of closing the air inlet 218. At this time, it is difficult for external air to flow into the interior of the main unit 20 through the air inlet 218. Figure 7 , indicating that the baffle 41 is in a state where the air inlet 218 is opened, and at this time, air can flow into the interior of the main unit 20 through the air inlet 218.

[0119] It is worth noting that the air inlet 218 provided in the embodiment of the present application is shown in FIG. Figure 7 and Figure 9 , rather than a grid, the entire area of ​​the air inlet 218 is hollowed out on the bottom shell 212. This not only makes it easier for the baffle 41 to open or close the air inlet 218, but also facilitates more airflow to enter through the air inlet 218, thereby improving the heat dissipation efficiency of the laptop computer 100.

[0120] In one example, when the baffle 41 is in a closed state, the outer side surface of the baffle 41 is in the same plane as the outer bottom surface of the main housing 21, thereby improving the aesthetics of the laptop computer 100. That is, in this example, when the baffle 41 is in a closed state, the baffle 41 is disposed within the air inlet 218, and the circumferential side surfaces of the baffle 41 are in contact with or have a gap with the circumferential side surfaces of the air inlet 218.

[0121] When the baffle 41 is in the state of opening the air inlet 218, the baffle 41 can prevent the hot air discharged from the air outlet 219 from flowing back to the air inlet 218, thereby improving the heat dissipation effect of the laptop computer 100, as follows: Figure 9 ,in Figure 9 The baffle 41 is not shown in the figure. The air inlet 218 includes a first side surface 2181 and a second side surface 2182 opposite to each other. The first side surface 2181 is closer to the air outlet 219 than the second side surface 2182. The baffle 41 can extend out of the main unit 20 and rotate in a direction away from the second side surface 2182. Figure 7 At this time, the air inlet 218 and the air outlet 219 are located on both sides of the baffle 41 along the Y-axis direction, and the baffle 41 can prevent the hot air discharged from the air outlet 219 from flowing back to the air inlet 218.

[0122] In one example, see Figure 9 A strip-shaped air inlet 218 is provided at the bottom of the main unit 20 , and a baffle 41 is provided at the air inlet 218 , or more than two baffles 41 are provided at the air inlet 218 , and each baffle 41 is provided in sequence along the length direction of the air inlet 218 .

[0123] In one example, more than two air inlets 218 are provided at the bottom of the main unit 20 , and the air inlets 218 are spaced apart along a length parallel to the air outlet 219 , and each air inlet 218 corresponds to a damper mechanism 40 .

[0124] In one example, the air inlet 218 is rectangular in shape, and the baffle 41 is also rectangular in shape to match the shape of the air inlet 218 .

[0125] In one example, the air inlet 218 is located between the side of the main housing 21 where the display screen 10 is located and the cooling fan 22. The air inlet 218 is close to the cooling fan 22. Figure 10 , illustrating the positions of the air inlet 218 and the cooling fan 22 , the inlet of the cooling fan 22 is close to the air inlet 218 , so that when the cooling fan 22 is working, external air enters the laptop computer 100 through the air inlet 218 .

[0126] In one example, only the air inlet 218 is provided at the bottom of the main body 20, or, in other examples, see Figure 11 At the bottom of the main unit 20, not only an air inlet 218 but also a grid air outlet 201 is provided. The grid air outlet 201 is provided on the side of the air inlet 218 away from the air outlet 219. When the cooling fan 22 in the main unit 20 is in operation, air can be taken in not only through the air inlet 218 but also through the grid air outlet 201, thereby improving the heat dissipation efficiency of the laptop computer 100. At the same time, when the baffle 41 is in the state of opening the air outlet 219, the baffle 41 can not only prevent the airflow discharged from the air outlet 219 from flowing back to the air inlet 218, but also prevent the airflow discharged from the air outlet 219 from flowing back to the grid air outlet 201, thereby improving the heat dissipation efficiency of the laptop computer 100.

[0127] In the embodiment of the present application, the baffle 41 is supported on the main unit 20. The baffle 41 may be directly supported on the main unit 20, or indirectly supported on the main unit 20. For example, the damper mechanism 40 further includes a driving device connected to the main unit 20, the driving device being connected to the baffle 41, and the driving device being configured to drive the baffle 41 to close or open the air inlet 218.

[0128] When the baffle 41 is directly supported on the main unit 20, the baffle 41 is rotatably connected to the main unit 20. For example, in one example, a support shaft is provided on the baffle 41, and the baffle 41 is supported on the bottom shell 212 of the main unit 20 through the support shaft, and is rotatably connected to the bottom shell 212 through the support shaft.

[0129] When the baffle 41 is rotatably connected to the bottom shell 212 of the main body 20, the damper mechanism 40 can be set to automatically control the opening of the baffle 41, or the damper mechanism 40 can be set to manually control the opening of the baffle 41.

[0130] For example, when the damper mechanism 40 is a mechanism that automatically controls the opening of the baffle 41, the damper mechanism 40 can be set to also include a drive motor, and the drive motor is directly connected to the support shaft on the baffle 41; or, the damper mechanism 40 can be set to include a drive motor and a gear transmission structure, and the drive motor is connected to the support shaft through the gear transmission structure.

[0131] In one example, the drive motor is connected to the processor in the host unit 20. When the processor receives a power-on signal from the laptop computer 100, the processor simultaneously controls the drive motor to start, and the drive motor works to drive the baffle 41 to open the air inlet 218. After the baffle 41 rotates to a preset angle, the drive motor is controlled to stop working; when the processor receives a laptop shutdown signal, the processor controls the drive motor to start, and the drive motor works to drive the baffle 41 relative to the air inlet 218.

[0132] When the damper mechanism 40 is a mechanism for manually controlling the opening of the baffle 41, in one example, the damper mechanism 40 includes a transmission structure that connects the baffle 41 and the display screen 10. For example, a transmission structure can be provided that connects the baffle 41 and the display housing 12 of the display screen 10. When the display screen 10 is opened relative to the host unit 20, the transmission structure can be driven to move the baffle 41. When the display screen 10 rotates in an open direction relative to the host unit 20, the display screen 10 can drive the transmission structure to move the baffle 41 toward opening the air inlet 218. When the display screen 10 rotates in a closed direction relative to the host unit 20, the display screen 10 can drive the transmission structure to move the baffle 41 toward closing the air inlet 218. In this example, by arranging the damper mechanism 40 in conjunction with the display screen 10, not only can the baffle 41 promptly open the air inlet 218 when the laptop computer 100 is in use, but the structure of the damper mechanism 40 can also be simplified.

[0133] In the embodiment of the present application, the laptop computer 100 is provided with a damper mechanism 40, so that when air needs to be taken in from the air inlet 218 at the bottom of the main body part 20, the baffle 41 of the damper mechanism 40 can be controlled to open the air inlet 218. The baffle 41 in the open state can prevent the hot air discharged from the air outlet 219 from flowing back to the air inlet 218, thereby improving the heat dissipation efficiency of the laptop computer 100. When air does not need to be taken in from the air inlet 218, the baffle 41 of the damper mechanism 40 can be controlled to close the air inlet 218, thereby preventing dust, hair and other debris from entering the interior of the laptop computer 100 while not affecting the aesthetics of the laptop computer 100.

[0134] See Figure 12-15 , Figure 12 This is a bottom view of the host unit 20 provided in the embodiment of the present application. Figure 2 , Figure 13 This is a bottom view of the host unit 20 provided in the embodiment of the present application. Figure 3 , Figure 14 This is a bottom view of the host unit 20 provided in the embodiment of the present application. Figure 4 , Figure 15 This is a bottom view of the host unit 20 provided in the embodiment of the present application. Figure 5 .

[0135] The outer bottom surface of the host part 20 includes a first area 2121 and a second area 2122. The first area 2121 is close to the side where the host part 20 is connected to the display part 10, and the second area 2122 is away from the side where the host part 20 is connected to the display part 10. Figure 12 , schematically showing the first area 2121 and the second area 2122, for easy observation, Figure 12 Two square dotted lines are shown in FIG. 2 to circle the first area 2121 and the second area 2122 .

[0136] In one embodiment, see Figure 12 Both the first area 2121 and the second area 2122 are provided with foot pads 30 , and the baffle 41 is located in the first area 2121 .

[0137] In one example, the two foot pads 30 in the first area 2121 are located on both sides of the baffle 41 .

[0138] In one example, the four foot pads 30 in the first area 2121 and the second area 2122 are respectively located at the four vertex positions of a rectangle.

[0139] In one example, when the baffle 41 is fully opened (ie, the baffle 41 is opened to the maximum angle), the baffle 41 is in contact with or out of contact with a supporting surface (such as a desktop) supporting the laptop computer 100 .

[0140] In one example, the foot pad 30 is made of silicone or rubber, which can effectively reduce noise and vibration.

[0141] In one example, the foot pad 30 is fixed to the bottom of the bottom shell 212 of the main body 20 by gluing or snapping.

[0142] In the embodiment of the present application, by providing foot pads 30 in both the first area 2121 and the second area 2122 , the laptop computer 100 is mainly supported on the support surface by the foot pads 30 , thereby facilitating stable support of the laptop computer 100 on the support surface.

[0143] In one embodiment, see Figure 13 A foot pad 30 is provided in the first area 2121 , a foot pad 30 is not provided in the second area 2122 , and the baffle 41 is located in the first area 2121 .

[0144] In one example, the two foot pads 30 in the first area 2121 are located on both sides of the baffle 41 .

[0145] In one example, when the baffle 41 is fully opened (ie, the baffle 41 is opened to the maximum angle), the baffle 41 is in contact with or out of contact with a supporting surface (such as a desktop) supporting the laptop computer 100 .

[0146] In the embodiment of the present application, the bottom surface of the main body 20 is mainly lifted by the foot pad 30 of the first area 2121, so that there is a certain distance between the air inlet 218 on the laptop computer 100 and the desktop, thereby ensuring that air in the external environment can flow into the air inlet 218.

[0147] In one embodiment, see Figure 14 , only the second area 2122 is provided with the foot pad 30, and the baffle 41 in the open state can support the main unit 20; or, in other embodiments, see Figure 15 No foot pads 30 are provided on the first area 2121 and the second area 2122 , and the baffle 41 in the open state can support the main unit 20 .

[0148] The baffle 41 that is set in an open state can not only prevent the hot air discharged from the air outlet 219 from flowing back to the air inlet 218, but also serve as the foot pad 30 to support the laptop computer 100, thereby reducing or even eliminating the foot pad 30, thereby simplifying the structure of the laptop computer 100.

[0149] In one example, a reinforcement structure is provided on the inner side surface of the baffle 41 , for example, the reinforcement structure may be a rib plate or a rib bar, so as to improve the strength of the baffle 41 .

[0150] Next, the damper mechanism 40 provided in the embodiment of the present application is further described in detail.

[0151] See Figure 16-17 , Figure 16 This is an exploded diagram of a laptop computer 100 provided in an embodiment of the present application. Figure 17 A partial top view of the transmission structure 44 provided in an embodiment of the present application connecting the baffle 41 and the pivot assembly 13.

[0152] In one embodiment, see Figure 17 The damper mechanism 40 includes a transmission structure 44, the display screen portion 10 includes a pivot assembly 13 for rotationally connecting with the host portion 20, the transmission structure 44 connects the pivot assembly 13 and the baffle 41, the baffle 41 is rotationally connected with the host portion 20, and when the display screen portion 10 rotates relative to the host portion 20, it can drive the baffle 41 to move.

[0153] In one example, see Figure 16 A relief groove 214 is provided in the middle area of ​​the rear end surface 213 of the main unit 20, and two protruding ends 217 of the main unit 20 are formed along the length direction of the relief groove 214; see Figure 16 The pivot assembly 13 includes a pivot body 132 and a connecting shaft 131. The two connecting shafts 131 are respectively arranged at both ends of the pivot body 132. The pivot body 132 is arranged in the avoidance groove 214 and the connecting shafts 131 at both ends of the pivot body 132 are respectively inserted into the corresponding protruding ends 217. The transmission structure 44 is connected to the pivot body 132 through the air outlet 219 on the main unit 20.

[0154] In one example, see Figure 16 The pivot assembly 13 further includes a connecting plate 134, which is located in the display screen portion 10 and is fixedly connected to the display housing 12 of the display screen portion 10. Figure 16 The display shell 12 includes a display shell body 121 and a cover plate 122. The display screen assembly 11 is set on the display shell body 121. The cover plate 122 is located below the display screen assembly 11. The connecting plate 134 is set between the display shell body 121 and the cover plate 122. The cover plate 122 is fixedly connected to the display shell body 121.

[0155] In one example, see Figure 17 The number of baffles 41 is one and the number of transmission structures 44 is two. The two transmission structures 44 are spaced apart along the length direction of the pivot assembly 13, and the connection position of each transmission structure 44 and the pivot body 132 is close to the end of the corresponding side of the pivot body 132.

[0156] In one example, see Figure 17The number of baffles 41 is one and the number of transmission structures 44 is two. The two transmission structures 44 are spaced apart along the length direction of the pivot assembly 13, and the connection position between each transmission structure 44 and the baffle 41 is close to the end of the corresponding side of the baffle 41, so as to facilitate stable force on the baffle 41.

[0157] In one example, the transmission structure 44 includes a gear portion, a rack portion, and a connecting rod. The gear portion is formed on the pivot body 132, the rack portion is meshed with the gear portion, and the connecting rod is rotatably connected to the rack portion and the baffle 41 respectively. The rotation of the pivot body 132 drives the gear portion to rotate, and the rotation of the gear portion drives the rack portion to move. The rack portion moves to push the connecting rod to enable the baffle 41 to open or close the air inlet 218.

[0158] In the embodiment of the present application, a transmission structure is provided to connect the baffle 41 and the pivot assembly 13, so that the baffle 41 is conveniently connected to the pivot assembly 13 of the display screen portion 10 in terms of spatial position. That is, while realizing the linkage between the baffle 41 and the display screen portion 10 without the need for an additional power source, it is also helpful to simplify the structure of the transmission structure 44.

[0159] In one embodiment, see Figure 17 The transmission structure 44 includes a sliding portion 42 and a connecting portion 43. The connecting portion 43 connects the sliding portion 42 and the baffle 41. The sliding portion 42 is connected to the pivot assembly 13. When the display screen portion 10 rotates, the pivot assembly 13 can drive the sliding portion 42 to move along the length direction of the pivot body 132 or the radial direction of the pivot body 132.

[0160] For example, when the pivot assembly 13 rotates forward, it can drive the sliding part 42 to move to the left along the length direction of the pivot assembly 13. When the pivot assembly 13 rotates backward, it can drive the sliding part 42 to move to the right along the length direction of the pivot assembly 13. When the sliding part 42 moves back and forth along the length direction of the pivot assembly 13, the connecting part 43 can drive the baffle 41 to open or close the air outlet 219; or, when the pivot assembly 13 rotates forward, it can drive the sliding part 42 to move forward in the radial direction of the pivot assembly 13. When the pivot assembly 13 rotates backward, it can drive the sliding part 42 to move backward in the radial direction of the pivot assembly 13. When the sliding part 42 moves back and forth in the radial direction of the pivot assembly 13, the connecting part 43 can drive the baffle 41 to open or close the air outlet 219.

[0161] In one example, the sliding portion 42 is threadedly connected to the pivot assembly 13 and the two form a screw structure, that is, the pivot assembly 13 is equivalent to a screw rod, and the sliding portion 42 is equivalent to a slider 432. When the pivot assembly 13 rotates, the sliding portion 42 can move along the axial direction (that is, the length direction) of the pivot assembly 13.

[0162] In one example, a cam is provided on the pivot assembly 13, and a cam groove is provided on the circumferential side of the cam. The length direction of the cam groove is along the circumferential direction of the cam. One end of the sliding portion 42 is inserted into the cam groove. When the pivot assembly 13 rotates, the sliding portion 42 slides in the cam groove and drives the sliding portion 42 to move along the radial direction of the pivot assembly 13.

[0163] In the embodiment of the present application, the sliding part 42 is connected to the pivot assembly 13 to convert the rotation of the pivot assembly 13 into a linear movement of the sliding part 42. The connecting part 43 moves back and forth in a linear direction to drive the baffle 41 to open or close the air outlet 219.

[0164] See Figures 18-22 , Figure 18 This is a partial schematic diagram of the transmission structure 44 connecting the baffle 41 and the pivot assembly 13 when the sliding portion 42 provided in the embodiment of the present application is inserted into the second end 13312 of the inclined groove of the sliding groove 133. Figure 19 This is a partial schematic diagram of the transmission structure 44 connecting the baffle 41 and the pivot assembly 13 when the sliding portion 42 provided in the embodiment of the present application is inserted into the straight groove portion 1332 of the sliding groove 133. Figure 20 This is a partial schematic diagram of the transmission structure 44 connecting the baffle 41 and the pivot assembly 13 when the sliding portion 42 provided in the embodiment of the present application is inserted into the first end 13311 of the inclined groove of the sliding groove 133. Figure 21 This is a schematic diagram of the structure of the transmission structure 44 provided in an embodiment of the present application. Figure 22 This is an exploded schematic diagram of the transmission structure 44 provided in an embodiment of the present application.

[0165] In one embodiment, see Figure 17 A sliding groove 133 is provided on the circumferential side surface of the pivot assembly 13. One end of the sliding portion 42 is inserted into the sliding groove 133 and the sliding portion 42 can slide along the length direction of the sliding groove 133. Figure 18 The sliding groove 133 at least includes an inclined groove portion 1331 , and the length of the inclined groove portion 1331 is along the axial direction of the pivot assembly 13 and along the circumferential direction of the pivot assembly 13 .

[0166] See Figure 18 , illustrating that one end of the sliding portion 42 is inserted into the inclined groove portion 1331. When the pivot assembly 13 rotates, the inclined groove portion 1331 squeezes the sliding portion 42 along the longitudinal sidewall of the groove and extends into the end of the inclined groove portion 1331, causing the sliding portion 42 to slide along the longitudinal direction of the slide groove 133, thereby achieving movement of the sliding portion 42 relative to the pivot assembly 13 along the axis of the pivot assembly 13. In addition, see Figure 18 , schematically shows that a connecting shaft 131 of the pivot assembly 13 is supported on the shaft seat 23 on the bottom shell 212.

[0167] See Figure 18 The length of the inclined groove portion 1331 is along the axial direction of the pivot assembly 13 and the circumferential direction of the pivot assembly 13. It can be understood that the inclined groove portion 1331 is not a straight groove extending only along the axial direction of the pivot assembly 13, nor is it an arc groove set only along the circumferential direction of the pivot assembly 13. The length of the inclined groove portion 1331 is along the axial direction of the pivot assembly 13 and the circumferential direction of the pivot assembly 13 at the same time.

[0168] In one example, see Figure 18 , the projection of the inclined groove portion 1331 in the XOY plane direction is a straight line; or, the projection of the inclined groove portion 1331 in the XOY plane direction is an arc shape; or, the projection of the inclined groove portion 1331 in the XOY plane direction is a wave shape formed by two arcs, etc.

[0169] It is worth noting that when the pivot assembly 13 rotates so that the sliding part 42 moves relative to the pivot assembly 13 along the axial direction of the pivot assembly 13, the moving direction of the sliding part 42 may be completely parallel to the axial direction of the pivot assembly 13. In addition, when the moving direction of the sliding part 42 is not completely parallel to the axial direction of the pivot assembly 13, that is, there is a relatively small angle with the axial direction of the pivot assembly 13, it can also be understood that when the pivot assembly 13 rotates, the sliding part 42 moves relative to the pivot assembly 13 along the axial direction of the pivot assembly 13.

[0170] See Figure 18 and Figure 19 Along the length extension direction of the inclined groove portion 1331, the inclined groove portion 1331 includes an inclined groove first end 13311 and an inclined groove second end 13312. The inclined groove first end 13311 is sequentially arranged along the axis direction of the pivot assembly 13 relative to the inclined groove second end 13312 and is sequentially arranged along the circumferential direction of the pivot assembly 13. Figure 20 , showing that one end of the sliding portion 42 is located at the first end 13311 of the inclined groove. At this time, the display unit 10 is in a state of being fastened to the main unit 20, and the baffle 41 is also in a state of closing the air inlet 218. When the display unit 10 is rotated, the sliding portion 42 can move along the inclined groove portion 1331 toward the second end 13312 of the inclined groove, so that the sliding portion 42 moves relative to the pivot assembly 13 along the axis direction of the pivot assembly 13. See Figure 18 , which shows that one end of the sliding portion 42 is located at the second end 13312 of the inclined groove. At this time, the display portion 10 is opened at a certain angle relative to the host portion 20, and the baffle 41 is also in a state of opening the air inlet 218.

[0171] In one example, the end of the sliding portion 42 extending into the sliding groove 133 is spherical or cylindrical with rounded corners.

[0172] In one example, see Figure 21 One end of the sliding portion 42 extending into the sliding groove 133 is sleeved with a sliding sleeve 45 for reducing friction, so that the sliding portion 42 can slide in the sliding groove 133.

[0173] In one example, the sliding sleeve 45 is made of metal, for example, copper.

[0174] In one example, the sliding sleeve 45 contacts the bottom surface of the sliding groove 133 , or in other examples, there is a gap between the sliding sleeve 45 and the bottom surface of the sliding groove 133 .

[0175] In the embodiment of the present application, by setting one end of the sliding portion 42 to be inserted into the inclined groove portion 1331 on the circumferential side of the pivot assembly 13, the sliding portion 42 can be driven to move relative to the pivot assembly 13 along the axial direction of the pivot assembly 13 when the display screen portion 10 is rotated, and the matching structure of the transmission structure 44 and the pivot assembly 13 is simple.

[0176] In one embodiment, see Figure 19 The slide groove 133 also includes a straight groove portion 1332, which is connected to one end of the oblique groove portion 1331 (the second end 13312 of the oblique groove). The straight groove portion 1332 is communicated with the oblique groove portion 1331, and the extension direction of the straight groove portion 1332 is along the circumferential direction of the pivot assembly 13; wherein, when the display screen portion 10 is opened at an angle not greater than a set angle, one end of the sliding portion 42 is inserted into the oblique groove portion 1331, and when the display screen portion 10 is opened at an angle greater than the set angle, one end of the sliding portion 42 is inserted into the straight groove portion 1332.

[0177] See Figure 19 , showing that one end of the sliding portion 42 is inserted into the straight groove portion 1332. Figure 20 When the display unit 10 is buckled onto the main unit 20, one end of the sliding portion 42 is located at the first end 13311 of the inclined slot. At this time, the baffle 41 closes the air inlet 218. When the display unit 10 is rotated, the sliding portion 42 can move along the inclined slot 1331 toward the second end 13312 of the inclined slot. The sliding portion 42 drives the connecting portion 43 to move, so that the connecting portion 43 drives the baffle 41 to rotate to open the air inlet 218. When the display unit 10 is opened to the set angle, see Figure 18One end of the sliding portion 42 is located at the second end 13312 of the oblique groove. When the display screen portion 10 continues to rotate and open, one end of the sliding portion 42 moves toward the straight groove portion 1332, and when the sliding portion 42 moves in the straight groove portion 1332 away from the second end 13312 of the oblique groove under the drive of the display screen portion 10, since the extension direction of the straight groove portion 1332 is along the circumferential direction of the pivot assembly 13, the sliding portion 42 will not move relative to the pivot assembly 13 along the longitudinal direction of the pivot assembly 13, and thus will not drive the connecting portion 43 to move, so that the connecting portion 43 continues to drive the baffle 41 to rotate.

[0178] When the display screen portion 10 is opened relative to the host portion 20 at an angle greater than a set angle, one end of the sliding portion 42 is located in the straight groove portion 1332. When the display screen portion 10 is rotated in the opposite direction to reduce the angle between the display screen portion 10 and the host portion 20, one end of the sliding portion 42 moves in the straight groove portion 1332 toward the second end 13312 of the inclined groove. At this time, the baffle 41 does not rotate relative to the host portion 20 (i.e., the angle of the baffle 41 remains unchanged). When the display screen portion 10 is rotated in the opposite direction until the angle between the display screen portion 10 and the host portion 20 is the set angle, When the angle is fixed, one end of the sliding portion 42 is located at the second end 13312 of the inclined groove. When the display screen portion 10 continues to be rotated in the opposite direction until the display screen portion 10 is buckled on the main unit 20, the sliding portion 42 can move along the inclined groove portion 1331 toward the first end 13311 of the inclined groove until one end of the sliding portion 42 is located at the first end 13311 of the inclined groove. When the sliding portion 42 moves along the inclined groove portion 1331, the baffle 41 gradually rotates in the direction of closing the air inlet 218 until the display screen portion 10 is buckled on the main unit 20, and the baffle 41 closes the air inlet 218.

[0179] That is to say, in the embodiment of the present application, when the sliding portion 42 slides in the oblique groove portion 1331, the sliding portion 42 will move relative to the pivot assembly 13 along the length direction of the pivot assembly 13, and then drive the connecting portion 43 to move so that the connecting portion 43 drives the baffle 41 to rotate; when the sliding portion 42 slides in the straight groove portion 1332, the sliding portion 42 will not move relative to the pivot assembly 13 along the length direction of the pivot assembly 13, and then will not drive the connecting portion 43 to move so that the connecting portion 43 drives the baffle 41 to rotate.

[0180] When using the laptop computer 100, different users may open the display screen 10 at different angles depending on their habits. If the slide groove 133 only includes the oblique groove portion 1331, the angle of the display screen 10 during use will affect the angle at which the baffle 41 opens. Therefore, in the embodiment of the present application, the sliding portion 42 includes not only the oblique groove portion 1331 but also the straight groove portion 1332. This ensures that when the display screen 10 of the laptop computer 100 is further opened from the preset angle, the angle of the baffle 41 is not affected. This ensures that even if the angle of the display screen 10 varies due to different user habits, the baffle 41 can still be opened to the same angle. Of course, it is worth noting that, in one example, the slide groove 133 may also include only the oblique groove portion 1331.

[0181] When the laptop computer 100 provided in the embodiment of the present application is in use, one end of the sliding portion 42 is located in the straight groove portion 1332. If the baffle 41 is subjected to an external force in the direction of closing the air inlet 218, if the baffle 41 wants to rotate in the direction of closing the air inlet 218, the sliding portion 42 needs to move relative to the pivot assembly 13 along the length direction of the pivot assembly 13. Since one end of the sliding portion 42 is located in the straight groove portion 1332 at this time, the sliding portion 42 cannot move along the length direction of the pivot assembly 13. Therefore, even if the baffle 41 is subjected to an external force in the direction of closing the air inlet 218, it will not drive the sliding portion 42 to move, and the display screen portion 10 will not rotate in the direction of being engaged with the host portion 20. Or, in other words, if the slide groove 133 only includes the oblique groove portion 1331, when the laptop computer 100 is in use, one end of the sliding portion 42 is located in the oblique groove portion 1331, that is, when the baffle 41 rotates in the direction of closing the air inlet 218, the sliding portion 42 will be driven by the connecting portion 43 to move along the oblique groove portion 1331, so that the display screen portion 10 will rotate in the direction of being engaged with the host portion 20.

[0182] In the embodiment of the present application, the sliding portion 42 is provided to include not only the oblique groove portion 1331 but also the straight groove portion 1332. Therefore, even if different users have different usage habits and thus the opening angles of the display screen portion 10 are different, the baffle 41 can be opened at the same angle. At the same time, when the baffle 41 is subjected to an external force in the direction of closing the air inlet 218, the display screen portion 10 will not rotate, that is, the movement can only be transmitted from the display screen portion 10 side to the baffle 41 side, otherwise it will get stuck.

[0183] In one embodiment, when the display screen portion 10 is opened at an angle not greater than a set angle, one end of the sliding portion 42 is inserted into the oblique groove portion 1331; when the display screen portion 10 is opened at an angle greater than a set angle, one end of the sliding portion 42 is inserted into the straight groove portion 1332, wherein the set angle has a value range of 60° to 90°.

[0184] For example, the value range of the set angle may be 60°~65°, 65°~70°, 75°~80°, or 85°~90°.

[0185] For example, when the display screen portion 10 is opened to an angle not greater than 90°, one end of the sliding portion 42 is inserted into the oblique groove portion 1331 ; and when the display screen portion 10 is opened to an angle greater than 90°, one end of the sliding portion 42 is inserted into the straight groove portion 1332 .

[0186] Typically, when using the laptop computer 100, the display screen 10 is opened at an angle greater than 90° so that the user can conveniently view the content displayed on the display screen 10. Therefore, in the embodiment of the present application, the set angle is set in a range of 60° to 90°, so that even if different users have different habits and thus open the display screen 10 at different angles, the bezel 41 can still be opened at the same angle.

[0187] In one embodiment, see Figure 21 The connecting portion 43 includes a fixing seat 431, a slider 432 and a connecting rod 433. Figure 18 and Figure 19 The fixed seat 431 is fixed in the main body 20, the slider 432 is movably connected to the fixed seat 431 and the fixed seat 431 guides the movement of the slider 432, the slider 432 is connected to the sliding part 42, the connecting rod 433 connects the slider 432 and the baffle 41, and the connecting rod 433 is rotatably connected to the slider 432 and the baffle 41. When the sliding part 42 moves along the length direction of the pivot assembly 13, the connecting rod 433 can drive the slider 432 to move on the fixed seat 431, so that the slider 432 can drive the connecting rod 433 to move.

[0188] See Figure 18 and Figure 19 The fixing base 431 is fixed to the inner side of the bottom shell 212 of the main body 20. In one example, the fixing base 431 is adhered to the bottom shell 212; in other examples, the fixing base 431 is detachably connected to the bottom shell 212.

[0189] The slider 432 is movably connected to the fixed seat 431 and the fixed seat 431 guides the movement of the slider 432. There is an angle between the movement direction of the slider 432 relative to the fixed seat 431 and the length direction of the pivot assembly 13. For example, the movement direction of the slider 432 relative to the fixed seat 431 is perpendicular to the length direction of the pivot assembly 13.

[0190] See Figure 18 and Figure 19The connecting rod 433 is rotatably connected to the slider 432 and the baffle 41. When the connecting rod 433 moves toward the baffle 41 driven by the slider 432, the connecting rod 433 can push the baffle 41 to rotate and open the air inlet 218. When the connecting rod 433 moves away from the baffle 41 driven by the slider 432, the connecting rod 433 can pull the baffle 41 to rotate and close the air inlet 218.

[0191] In one example, see Figure 18 A slider connecting ear 4321 is set on the slider 432, and the two slider connecting ears 4321 are arranged relatively spaced apart. One end of the connecting rod 433 is inserted between the two slider connecting ears 4321, and the connecting shaft connects the two slider connecting ears 4321 and one end of the connecting rod 433.

[0192] In one example, see Figure 18 A baffle connecting ear 411 is set on the inner side of the baffle 41, and the two baffle connecting ears 411 are set relatively spaced apart. The other end of the connecting rod 433 is inserted between the two baffle connecting ears 411, and the connecting shaft connects the two baffle connecting ears 411 and one end of the connecting rod 433.

[0193] In the embodiment of the present application, by providing the connecting portion 43 including a fixing seat 431 , a sliding block 432 and a connecting rod 433 , the structure of the damper mechanism 40 can be simplified.

[0194] In one embodiment, see Figure 21 , a first protrusion 423 is formed on the sliding portion 42, a slider groove 4322 is provided on the slider 432, the first protrusion 423 is inserted into the slider groove 4322 and the first protrusion 423 can move along the length direction of the slider groove 4322; see Figure 18 and Figure 19 The slider slot 4322 extends in a direction parallel to the axis of the pivot assembly 13 and extends in a direction from close to the baffle 41 to away from the baffle 41.

[0195] See Figure 18 and Figure 20 Along the length extension direction of the slider groove 4322, the slider groove 4322 includes a slider groove first end 43221 and a slider groove second end 43222, the slider groove second end 43222 is arranged in sequence relative to the slider groove first end 43221 along a direction parallel to the axis of the pivot assembly 13, and the slider groove second end 43222 is arranged away from the baffle 41 relative to the slider groove first end 43221.

[0196] In one example, see Figure 20 , the projection of the slider groove 4322 in the XOY plane direction is a straight line; or, the projection of the slider groove 4322 in the XOY plane direction is an arc shape.

[0197] See Figure 20 When one end of the sliding portion 42 is inserted into the first end 13311 of the inclined groove, the first protrusion 423 is located at the first end 43221 of the slider groove. When the sliding portion 42 moves along the inclined groove portion 1331 toward the second end 13312 of the inclined groove, the sliding portion 42 moves in the direction indicated by the arrow opposite to the X-axis, and the first protrusion 423 moves along the slider groove 4322 toward the second end 43222 of the slider groove. Since the second end 43222 of the slider groove is away from the baffle 41 relative to the first end 43221 of the slider groove, the slider 432 is pushed toward the baffle 41, thereby causing the connecting rod 433 connected to the slider 432 to push the baffle 41 to rotate in the direction of opening the air inlet 218; see Figure 18 When one end of the sliding portion 42 extends into the second end 13312 of the inclined slot, the first protrusion 423 is located at the second end 43222 of the slider slot. When one end of the sliding portion 42 slides within the straight slot 1332, the sliding portion 42 does not move along the length of the pivot assembly 13, and thus the slider 432 does not move relative to the fixing seat 431, and thus the baffle 41 does not rotate relative to the main unit 20.

[0198] See Figure 18 , illustrating that when one end of the sliding portion 42 extends into the second end 13312 of the inclined groove, the first protrusion 423 is located at the second end 43222 of the slider groove. When the sliding portion 42 moves along the inclined groove portion 1331 toward the first end 13311 of the inclined groove, the first protrusion 423 moves along the slider groove 4322 toward the first end 43221 of the slider groove. Since the second end 43222 of the slider groove is away from the baffle 41 relative to the first end 43221 of the slider groove, the slider 432 is pulled to move in the direction away from the baffle 41, and then the connecting rod 433 connected to the slider 432 pulls the baffle 41 to rotate in the direction of closing the air inlet 218.

[0199] It is worth mentioning that Figure 18 It shows that when one end of the sliding portion 42 extends into the second end 13312 of the inclined groove, the first protrusion 423 is located at the second end 43222 of the slider groove. Figure 20 It illustrates that when one end of the sliding portion 42 is inserted into the first end 13311 of the inclined groove, the first protrusion 423 is located at the first end 43221 of the slider groove, that is, the length of the projection of the slider groove 4322 in the XOY plane direction is equal to the length of the projection of the slide groove 133 in the XOY plane direction. In other examples, the length of the projection of the slider groove 4322 in the XOY plane direction can also be set to be greater than the length of the projection of the slide groove 133 in the XOY plane direction.

[0200] In the embodiment of the present application, by setting the first protrusion 423 on the sliding part 42 to be inserted into the slider groove 4322 on the slider 432, the sliding part 42 can move along the length direction of the pivot assembly 13 to drive the slider 432 to move in the direction close to the baffle 41 and away from the baffle 41. At the same time, the connection structure between the sliding part 42 and the slider 432 is simple.

[0201] In one embodiment, see Figure 21 and Figure 22 The fixing seat 431 is provided with a first guide groove 4311, and the slider 432 is provided in the first guide groove 4311, along the axis direction parallel to the pivot assembly 13, that is, Figure 21 The two opposite ends of the slider 432 in the X-axis direction are in contact with the groove wall of the first guide groove 4311, and the slider 432 is ... Figure 21 The length of the first guide groove 4311 in the middle Y-axis direction is greater than the length of the slider 432 , that is, the slider 432 can move relative to the fixing seat 431 in a direction perpendicular to the axis of the pivot assembly 13 .

[0202] In one example, see Figure 22 The slider 432 includes an upper slider segment 4323 and a lower slider segment 4324. The upper slider segment 4323 is arranged above the lower slider segment 4324 and the two are connected, along the axis direction parallel to the pivot assembly 13, that is, Figure 22 In the middle X-axis direction, at least one of the two ends of the lower slider segment 4324 protrudes from the end of the corresponding side of the upper slider segment 4323. Figure 22 , indicating that both ends of the lower slider segment 4324 protrude from the ends of the corresponding sides of the upper slider segment 4323.

[0203] In one example, the slider 432 is an integrally formed structure.

[0204] In one example, see Figure 22 One end of the first guide groove 4311 is connected to the end of the fixed seat 431 away from the sliding part 42, so as to avoid the slider connecting ear 4321 and the connecting rod 433, and to facilitate the insertion of the slider 432 into the fixed seat 431 through one end of the first guide groove 4311.

[0205] In the embodiment of the present application, by providing the first guide groove 4311 on the fixing seat 431 and the slider 432 being provided in the first guide groove 4311 , not only can the fixing seat 431 guide the movement of the slider 432 , but the connection structure between the two is also simple.

[0206] In one embodiment, see Figure 21A second protrusion 424 is formed on the sliding portion 42 , a second guide groove 4312 is provided on the fixing seat 431 , the second protrusion 424 is inserted into the second guide groove 4312 , and the length extension direction of the second guide groove 4312 is parallel to the axial direction of the pivot assembly 13 .

[0207] In one example, see Figure 22 The second protrusion 424 includes an upper protrusion section 4241 and a lower protrusion section 4242. The lower protrusion section 4242 is along Figure 22 At least one of the two ends in the Y-axis direction protrudes from the end portion of the corresponding side of the upper raised section 4241, see Figure 22 , showing the lower raised section 4242 along Figure 22 The ends of the upper protrusion section 4241 protrude from the ends at the corresponding sides of the middle Y-axis direction, and the shape of the second guide groove 4312 matches the shape of the second protrusion 424 to prevent the second protrusion 424 from separating from the fixing seat 431 upward along the Z-axis direction.

[0208] In one example, the second guide groove 4312 is arranged along the length direction (ie Figure 22 At least one end of the two ends (in the X-axis direction) is connected to the corresponding side surface of the fixing seat 431, so that the second protrusion 424 can be inserted into the fixing seat 431 from one end of the second guide groove 4312.

[0209] In one example, see Figure 22 The sliding portion 42 includes a sliding rod 421, a sliding body 422, a first protrusion 423 and a second protrusion 424. The first protrusion 423 and the second protrusion 424 are arranged on the bottom surface of the sliding body 422 and close to the two ends of the sliding body 422. The sliding rod 421 is arranged on the top surface of the sliding body 422 and close to one end of the sliding body 422. The sliding rod 421 is located above the second protrusion 424, and one end of the sliding rod 421 extends into the sliding groove 133.

[0210] In one example, the sliding portion 42 is an integrally formed structure.

[0211] In the embodiment of the present application, the second protrusion 424 on the sliding portion 42 is inserted into the second guide groove 4312 on the fixing seat 431 , so that the limiting sliding portion 42 can stably move along the length direction parallel to the pivot assembly 13 .

[0212] The above describes that the second protrusion 424 on the sliding part 42 is inserted into the second guide groove 4312 on the fixed seat 431. It is worth noting that the sliding part 42 may also be set not to include the second protrusion 424 and the second guide groove 4312 is not set on the fixed seat 431. For example, in one embodiment, a matching structure of the first protrusion 423 and the slider groove 4322 may also be set, so that the first protrusion 423 cannot be separated from the slider groove 4322 upward along the Z-axis direction. For example, a limiting ball head may be set at the free end of the first protrusion 423, and the diameter of the limiting ball head may be larger than the diameter of the cross section of the first protrusion 423, so that the first protrusion 423 cannot be separated from the slider groove 4322 upward along the Z-axis direction, thereby allowing the sliding part 42 to move stably along the length direction of the pivot assembly 13.

[0213] The above description shows that the first protrusion 423 on the sliding part 42 is inserted into the slider groove 4322 on the slider 432 to realize the connection between the sliding part 42 and the slider 432. It is worth noting that the first protrusion 423 on the sliding part 42 may also be inserted into the slider groove 4322 on the slider 432. For example, in one embodiment, the connecting part 43 also includes an auxiliary fixing seat, which is fixed on the inner side surface of the bottom shell 212 of the main unit 20. The sliding part 42 is slidably connected to the auxiliary fixing seat, and the auxiliary fixing seat guides the sliding part 42 to move along the length direction of the pivot assembly 13. The sliding part 42 and the slider 432 are connected through an intermediate connecting rod, and the intermediate connecting rod is rotatably connected to the sliding part 42 and the slider 432. When the sliding part 42 moves along the length direction of the pivot assembly 13, the slider 432 is pulled or pushed to move on the fixing seat 431 through the intermediate connecting rod.

[0214] See Figure 23-Figure 27 , Figure 23 This is a schematic top view of the portion where the baffle 41 provided in the embodiment of the present application is connected to the bottom shell 212 of the main unit 20. Figure 24 for Figure 23 A partial enlarged view of point C in the middle. Figure 25 This is a partial enlarged view of the baffle 41 and the bottom shell 212 of the main unit 20 provided in the embodiment of the present application in an exploded state. Figure 26 This is a partial enlarged view of the baffle 41 and the bottom shell 212 in a cross-sectional state provided in an embodiment of the present application. Figure 27 This is another partial enlarged view of the baffle 41 and the bottom shell 212 provided in the embodiment of the present application in a cross-sectional state.

[0215] In one embodiment, see Figure 25 The first side surface 2181 of the air inlet 218 is an arc concave surface, one end of the baffle 41 extends toward the first side surface 2181 , and the end of the baffle 41 extending toward the first side surface 2181 is an arc convex surface 412 matching the arc concave surface.

[0216] The first side surface 2181 cooperates with the arc convex surface 412, so that the first side surface 2181 of the air inlet 218 is set to fit the arc convex surface 412 of the baffle 41. The axis corresponding to the arc convex surface 412 on the baffle 41 is the rotation axis of the baffle 41. When the baffle 41 rotates relative to the bottom shell 212 of the main unit 20, the baffle 41 can rotate around the axis of the arc convex surface 412.

[0217] When the baffle 41 closes the air inlet 218, the baffle 41 is arranged inside the air inlet 218, that is, the circumferential side surfaces of the baffle 41 are respectively facing the circumferential side surfaces of the corresponding sides of the air inlet 218. In one example, when the baffle 41 closes the air inlet 218, the circumferential side surfaces of the baffle 41 are in contact with the circumferential side surfaces of the air inlet 218.

[0218] In the embodiment of the present application, the first side surface 2181 of the air inlet 218 is set as an arc concave surface and an arc convex surface 412 is set on the baffle 41 to match the arc concave surface, so that the baffle 41 can be set in the air inlet 218 while facilitating the rotation of the baffle 41 relative to the bottom shell 212 of the main unit 20.

[0219] In one embodiment, see Figure 25 One or more baffle grooves 413 are provided on the inner side surface of the baffle 41 . The baffle grooves 413 are close to one side of the arc convex surface 412 and open to the arc convex surface 412 . A first matching protrusion 414 is provided in each baffle groove 413 .

[0220] One or more baffle grooves 413 are provided on the inner side surface of the baffle 41 , that is, one baffle groove 413 can be provided on the inner side surface of the baffle 41 , or more than two baffle grooves 413 can be provided, and each baffle groove 413 is provided in sequence and spaced apart along the length direction of the baffle 41 .

[0221] See Figure 25 A bottom shell groove 2123 is provided on the inner side surface of the bottom shell 212, the bottom shell groove 2123 is close to the first side surface 2181 and is connected to the first side surface 2181, a limiting member 2124 is provided on the bottom surface of the bottom shell groove 2123, and a circular arc groove surface 21241 is provided on the limiting member 2124.

[0222] See Figure 25 and Figure 26 The first mating protrusion 414 is inserted into the arc groove surface 21241 on the limit member 2124 and the first mating protrusion 414 is rotatably connected to the limit member 2124. When the baffle 41 rotates, the second mating protrusion 415 rotates relative to the limit member 2124, that is, the axis of the second mating protrusion 415 is the rotation axis of the baffle 41.

[0223] In one example, the cross section of the first mating protrusion 414 (the cross section parallel to the YOZ) is semicircular, that is, the first mating protrusion 414 is half cylindrical, and the arc surface of the first mating protrusion 414 faces upward along the Z-axis direction.

[0224] In one example, see Figure 25 Two first matching protrusions 414 are provided on each baffle groove 413, and two limiting members 2124 are also provided on each bottom shell slot 2123. The two first matching protrusions 414 on each baffle groove 413 are respectively connected to the two limiting members 2124 on the bottom shell slot 2123.

[0225] In the embodiment of the present application, the first mating protrusion 414 is provided to cooperate with the limiting member 2124 , so as to facilitate the stable rotation connection between the baffle 41 and the bottom shell 212 .

[0226] In one embodiment, see Figure 25 Each baffle groove 413 is further provided with a second mating protrusion 415, see Figure 27 , the second matching protrusion 415 extends toward the corresponding bottom shell groove 2123 .
