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] The host housing of an existing laptop computer is provided with a fan and a heating element, and the host housing is provided with a heat dissipation inlet and a heat dissipation outlet. The fan drives the air in the external environment to enter the host housing from the heat dissipation inlet, and the air flows through the heating element to remove the heat and flows out from the heat dissipation outlet. However, due to the lack of a blocking structure between the heat dissipation inlet and the heat dissipation outlet, the hot air discharged from the heat dissipation outlet will flow to the heat dissipation inlet, thereby affecting the heat dissipation effect of the laptop computer. 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 to a heat dissipation inlet, thereby affecting the heat dissipation effect of the laptop computer.

[0004] The technical solution is as follows: A first aspect of the present application provides a laptop computer, comprising: Display screen unit; The host part is rotatably connected to the display part, an air inlet is arranged at the bottom of the host part, and an air outlet is arranged at one end of the host part close to the end rotatably connected to the display part; A damper mechanism, the damper mechanism comprising a baffle for opening or closing the air inlet; The baffle is supported on the main unit, the air inlet includes a first side surface and a second side surface opposite to each other, the second side surface is closer to the air outlet than 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.

[0005] 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 block 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 computer without affecting the aesthetics of the laptop computer.

[0006] 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.

[0007] In this implementation, by providing a transmission structure to connect the baffle plate and the pivot assembly, the baffle plate is conveniently connected to the pivot assembly of the display screen portion in terms of spatial position, thereby facilitating the simplification of the structure of the transmission structure.

[0008] In some implementations, the transmission structure includes a sliding part and a connecting part, the connecting part connects the sliding part and the baffle, the sliding part is movably connected to the pivot assembly, and when the display screen part rotates, the pivot assembly can drive the sliding part to move along the length direction of the pivot assembly or the radial direction of the pivot body.

[0009] In this implementation, the sliding part is connected to the pivot assembly to convert the rotation into linear movement, and the connecting part drives the baffle to open or close the air outlet through the reciprocating movement of the connecting part along the linear direction.

[0010] 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 at least includes an inclined groove portion, and the length of the inclined groove portion runs along the axial direction of the pivot assembly and along the circumferential direction of the pivot assembly.

[0011] 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 matched.

[0012] In some implementations, the slide groove also includes a straight groove portion, which is connected to one end of the oblique groove portion, and an extension direction of the straight groove portion is along the circumferential direction of the pivot assembly; wherein, when the display screen portion is opened at an angle not greater than a set angle, one end of the sliding portion is inserted into the oblique groove portion, and when the display screen portion is opened at an angle greater than a set angle, one end of the sliding portion is inserted into the straight groove portion.

[0013] In the present implementation, the sliding portion is provided to include not only an inclined groove portion but also a straight groove portion, so that the baffle can be opened at the same angle even if the angle of the display screen portion is different due to different user habits. 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.

[0014] In some implementations, the angle is set to a value range of 60° to 90°.

[0015] Usually, when using a laptop computer, the opening angle of the display screen is greater than 90°, so that the user can conveniently observe the content displayed on the display screen. Therefore, in the embodiment of the present application, the value range of the set angle is set to 60°~90°, so that even if the angle of the display screen is different due to different user habits, the angle of the baffle opening can be the same.

[0016] In some implementations, one end of the sliding portion extending into the sliding groove is sleeved with a sliding sleeve for reducing friction, so that the sliding portion can slide in the sliding groove.

[0017] 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, 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 and then the slider drives the connecting rod to move.

[0018] In this implementation, by providing a connecting portion including a fixing seat, a sliding block and a connecting rod, the structure of the damper mechanism can be simplified.

[0019] 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 in a direction from close to the baffle to away from the baffle.

[0020] 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.

[0021] In some implementations, a first guide groove is provided on the fixed seat, and a 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.

[0022] In this implementation, by providing the first guide groove on the fixing seat and the sliding block in the first guide groove, not only the fixing seat can guide the movement of the sliding block, but also the connection structure between the two is simple.

[0023] 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 a length extension direction of the second guide groove is parallel to an axial direction of the pivot assembly.

[0024] 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 position-limiting sliding portion can stably move along a length direction parallel to the pivot assembly.

[0025] In some implementations, there are two transmission structures, which are spaced apart along the length direction 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.

[0026] 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 as to facilitate uniform force on the baffle.

[0027] In some implementations, the first side surface is an arc 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 arc convex surface matching the arc concave surface.

[0028] In this implementation, the first side surface of the air inlet is set as an arc concave surface and an arc convex surface matching the arc concave surface is set on the baffle, so that the baffle can be set in the air inlet and can be rotated relative to the bottom shell of the main unit.

[0029] In some implementations, one or more baffle grooves are provided on the inner side surface of the baffle, the baffle grooves are close to one side of the arc convex surface and open to the arc convex surface, and each baffle groove is provided with a first matching protrusion; 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 with the arc concave surface, a limiting member is provided on the bottom surface of the groove of the bottom shell, an arc groove surface is provided on the limiting member, a first matching protrusion is inserted into the arc groove surface and the first matching protrusion is rotatably connected to the limiting member.

[0030] In some implementations, a second mating protrusion is further disposed in each baffle groove, and the second mating protrusions extend toward the corresponding bottom shell grooves respectively.

[0031] 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 match with the limiting member.

[0032] 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, and the air inlet is close to the cooling fan.

[0033] In this implementation, the air inlet is arranged close to the cooling fan so that when the cooling fan is working, external air can enter the content of the laptop through the air inlet.

[0034] In some implementations, the outer bottom surface of the host part includes a first area and a second area, the first area is close to the side where the host part is connected to the display part, and the second area is away from the side where the host part is connected to the display part, 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.

[0035] 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.

[0036] In some implementations, only the second area is provided with foot pads, and the baffle in an open state can support the host unit; or, no foot pads are provided on the first area and the second area, and the baffle in an open state can support the host unit.

[0037] 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 to simplify the structure of the laptop computer.

In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0045] It should be noted that, in this application, words such as "in one embodiment", "exemplarily", "for example", etc. are used to indicate examples, illustrations or descriptions. Any embodiment or design described in this application as "in one embodiment", "exemplarily", "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "in one embodiment", "exemplarily", "for example", etc. is intended to present related concepts in a specific way.

[0046] 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.

[0047] See also Figure 1-Figure 3 , Figure 1 is a structural schematic diagram of a related existing notebook computer 100 in an open state, Figure 2 FIG. 1 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 .

[0048] See also Figure 1 The notebook computer 100 generally includes a display screen portion 10 and a host portion 20, wherein the display screen portion 10 is rotatably connected to one end of the host portion 20. The host portion 20 includes a host housing 21', see Figure 1 A heat dissipation inlet 211' is provided at the bottom of the host housing 21', and a heat dissipation outlet 212' is provided at one end of the host part 20 and the display part 10 that are rotatably connected. A fan and a heating element are provided inside the host housing 21' of the notebook computer 100. The fan drives air in the external environment to enter the host housing 21' from the heat dissipation inlet 211', and the air flows through the heating element to take away the heat and flows out from the heat dissipation outlet 212'.

[0049] See also Figure 1 The bottom of the host housing 21' is also protruded 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'.

[0050] See also Figure 2 and Figure 3 The heat dissipation inlet 211' on the host housing 21' is usually in a grid shape, and the gap between the grids is relatively small, which can block 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.

[0051] See also Figure 2 , schematically showing 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 2The solid arrows indicate airflow flowing in from the heat dissipation inlet 211', and the dotted arrows indicate 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 host housing 21' under the action of the fan in the host housing 21', thereby allowing the hot air to re-enter the interior of the notebook computer 100, affecting the heat dissipation effect of the notebook computer 100. The electronic components in the notebook computer 100 are kept in a high temperature state for a long time and are easily damaged, affecting the service life of the notebook computer 100.

[0052] See also Figure 3 , schematically shows the foot pads 30 located at the heat dissipation inlet 211' and the heat dissipation outlet 212'. The length of the foot pads 30 is not less than the length of the heat dissipation inlet 211'. That is, it can be understood that a sufficiently long foot pad 30 can be set so that the foot pad 30 can block the hot air discharged from the heat dissipation outlet 212' from flowing back toward the heat dissipation inlet 211'. However, if the foot pad 30 is too long, there will be some problems, such as affecting the overall appearance of the notebook computer 100, the foot pad 30 is fixed to the host housing 21' by glue, the foot pad 30 has a large contact area and is prone to debonding after long-term stress, and an overly long foot pad 30 also increases the difficulty of assembly.

[0053] 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 part 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 block 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.

[0054] The laptop computer 100 provided in the embodiment of the present application is further described below in conjunction with the accompanying drawings.

[0057] It is worth noting that the qualifiers of the parallel and / or perpendicular positional relationships mentioned in this embodiment are all for the current technological level, rather than absolute and strict definitions in the 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 directional terms are mainly based on the position of the laptop computer 100 relative to the attached 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".

The top housing 211 and the bottom housing 212 together define a receiving cavity for accommodating components such as a cooling fan 22 and a heating element. In an example, the material of the main housing 21 may be selected from metals such as aluminum and carbon steel, so that the main housing 21 has high strength and good structural stability.

[0060] See also 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 . The display screen assembly 11 is used to display images.

[0061] See also Figure 4 and Figure 6 The display screen 10 is close to one end of the host 20, and the display screen 10 is rotatably connected to the host 20. The angle between the display screen 10 and the host 20 can be adjusted by rotating the display screen 10 and the host 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 covers 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.

[0062] 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, two connecting shafts 131 may be provided on the host portion 20, and a shaft seat 23 may be provided on the display screen portion 10, and the two connecting shafts 131 on the host portion 20 are 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.

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 respectively opened to the upper top surface 215 and the lower bottom surface 216 of the main body 20, and the avoidance groove 214 is 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 arranged 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, the shaft seat 23 can be arranged on the upper top surface 215 of the host part 20 along the thickness direction, and the two shaft seats 23 are close to the rear side end surface 213 of the host part 20, and the two connecting shafts 131 on the display part 10 are respectively inserted into the two shaft seats 23 on the upper top surface 215 of the host part 20.

[0064] In the embodiments of this application, please refer to Figure 7 The bottom of the main unit 20, i.e., 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 in the external environment to enter the main unit housing 21 from the air inlet 218. The air flows through the heating element to take away heat and flows out from the air outlet 219.

[0065] The laptop computer 100 provided in the embodiment of the present application further includes a damper mechanism 40, and the damper mechanism 40 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 which time it is difficult for external air to flow into the interior of the host unit 20 through the air inlet 218, see Figure 7 , which shows that the baffle 41 is in a state where the air inlet 218 is opened, and air can flow into the interior of the main unit 20 through the air inlet 218.

[0066] It is worth noting that the air inlet 218 provided in the embodiment of the present application is shown in FIG. Figure 7 and Fig. 9 , rather than a grid-like shape, the entire area of ​​the air inlet 218 is hollowed out on the bottom shell 212 , so that it is not only convenient for the baffle 41 to open or close the air inlet 218 , but also conducive to more airflow entering through the air inlet 218 , so as to improve the heat dissipation efficiency of the laptop computer 100 .

[0067] 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, so as to improve the aesthetics of the notebook computer 100. That is, in this example, when the baffle 41 is in a closed state, the baffle 41 is disposed in the air inlet 218, and the side surface of the baffle 41 along the circumferential direction is in contact with or has a gap with the side surface of the air inlet 218 along the circumferential direction.

[0068] 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 notebook computer 100, as follows: Fig. 9,in Fig. 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, and the baffle 41 can extend out of the host part 20 and rotate in a direction away from the second side surface 2182, see 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.

[0069] In one example, see Fig. 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 .

[0070] In one example, more than two air inlets 218 are disposed 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 .

[0071] 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 .

[0072] In one example, the air inlet 218 is located between the side of the main housing 21 where the display screen portion 10 is disposed and the cooling fan 22, and the air inlet 218 is close to the cooling fan 22. Fig.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 notebook computer 100 through the air inlet 218 .

[0073] In one example, only the air inlet 218 is provided at the bottom of the host part 20, or, in other examples, see Fig.11 At the bottom of the host part 20, not only an air inlet 218 but also a grid air outlet 201 is arranged. The grid air outlet 201 is arranged on the side of the air inlet 218 away from the air outlet 219. When the cooling fan 22 in the host part 20 is in working state, 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.

[0074] 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 the baffle 41 may be indirectly supported on the main unit 20. For example, the damper mechanism 40 further includes a driving device, which is connected to the main unit 20 and connected to the baffle 41. The driving device is used to drive the baffle 41 to move so that the baffle 41 closes the air inlet 218 or opens the air inlet 218.

[0075] When the baffle 41 is directly supported on the main unit 20, the baffle 41 is rotationally connected to the main unit 20. For example, in one example, a supporting 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 supporting shaft, and is rotationally connected to the bottom shell 212 through the supporting shaft.

[0076] When the baffle 41 is rotatably connected to the bottom shell 212 of the main unit 20 , the damper mechanism 40 can be set to be a mechanism for automatically controlling the opening of the baffle 41 , or the damper mechanism 40 can be set to be a mechanism for manually controlling the opening of the baffle 41 .

[0077] 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 arranged to also include a drive motor, and the drive motor is directly connected to the supporting shaft on the baffle 41; or, the damper mechanism 40 can be arranged to include a drive motor and a gear transmission structure, and the drive motor is connected to the supporting shaft through the gear transmission structure.

[0078] 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 controls the drive motor to start at the same time. 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.

[0079] 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, and the transmission structure connects the baffle 41 and the display screen portion 10. For example, a transmission structure can be provided to connect the baffle 41 and the display housing 12 of the display screen portion 10, and the baffle 41 can be driven to move when the display screen portion 10 is opened relative to the host portion 20. When the display screen portion 10 rotates in the opening direction relative to the host portion 20, the display screen portion 10 can drive the transmission structure to move so that the baffle 41 moves in the direction of opening the air inlet 218. When the display screen portion 10 rotates in the closing direction relative to the host portion 20, the display screen portion 10 can drive the transmission structure to move so that the baffle 41 moves in the direction of closing the air inlet 218. In this example, by setting the damper mechanism 40 to be linked with the display screen portion 10, not only can the baffle 41 open the air inlet 218 in time when the laptop computer 100 is used, but also the structure of the damper mechanism 40 can be simplified.

[0080] 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 unit 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 block 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, so as to prevent dust, hair and other debris from entering the interior of the laptop computer without affecting the aesthetics of the laptop computer 100.

[0081] See also Figure 12-Figure 15 , Fig.12 A bottom view of the host unit 20 provided in the embodiment of the present application Figure 2 , Fig.13 A bottom view of the host unit 20 provided in the embodiment of the present application Figure 3 , Fig.14 A bottom view of the host unit 20 provided in the embodiment of the present application Figure 4 , Fig.15 A bottom view of the host unit 20 provided in the embodiment of the present application Figure 5 .

[0082] 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 far away from the side where the host part 20 is connected to the display part 10. Fig.12 , showing the first area 2121 and the second area 2122, for easy observation, Fig.12 Two square dotted lines are shown in the figure to circle the first area 2121 and the second area 2122.

[0083] In one embodiment, see Fig.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 .

[0084] In one example, the two foot pads 30 of the first area 2121 are located on both sides of the baffle 41 .

[0085] In one example, the four foot pads 30 of the first area 2121 and the second area 2122 are respectively located at the four vertex positions of a rectangle.

[0086] 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 not in contact with a supporting surface (such as a desktop) supporting the notebook computer 100 .

[0087] In one example, the foot pad 30 is made of silicone or rubber, which can effectively reduce noise and vibration.

[0088] In one example, the foot pad 30 is fixed to the bottom of the bottom shell 212 of the main unit 20 by gluing or snapping.

[0089] 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 , so that the laptop computer 100 is stably supported on the support surface.

[0090] In one embodiment, see Fig.13 The first area 2121 is provided with a foot pad 30 , the second area 2122 is not provided with a foot pad 30 , and the baffle 41 is located in the first area 2121 .

[0091] In one example, the two foot pads 30 of the first area 2121 are located on both sides of the baffle 41 .

[0092] 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 not in contact with a supporting surface (such as a desktop) supporting the notebook computer 100 .

[0093] In the embodiment of the present application, the bottom surface of the host part 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 notebook computer 100 and the desktop, thereby ensuring that the air in the external environment can flow into the air inlet 218.

[0094] In one embodiment, see Fig.14 , only the second area 2122 is provided with the foot pad 30, and the baffle 41 in the open state can support the host part 20; or, in other embodiments, see Fig.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 host part 20 .

[0095] 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, so as to simplify the structure of the laptop computer 100.

[0096] In one example, a reinforcement structure is disposed on the inner side 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 .

[0097] Next, the damper mechanism 40 provided in the embodiment of the present application is further described in detail.

[0098] See also Figure 16-Figure 17 , Fig.16 The exploded schematic diagram of the notebook computer 100 provided in the embodiment of the present application is as follows: Fig.17 A partial top view schematically showing the transmission structure 44 provided in an embodiment of the present application connecting the baffle 41 and the pivot assembly 13 .

[0099] In one embodiment, see Fig.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 the display screen portion 10 can drive the baffle 41 to move when it rotates relative to the host portion 20.

[0100] In one example, see Fig.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 Fig.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.

[0101] In one example, see Fig.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. Fig.16The 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.

[0102] In one example, see Fig.17 The number of baffles 41 is one and the number of transmission structures 44 is two. The two transmission structures 44 are arranged at intervals 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.

[0103] In one example, see Fig.17 The number of baffles 41 is one and the number of transmission structures 44 is two. The two transmission structures 44 are arranged at intervals 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 the baffle 41 to be stably stressed.

[0104] 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.

[0105] 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.

[0106] In one embodiment, see Fig.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, and 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.

[0107] For example, when the pivot assembly 13 rotates forward, the sliding part 42 can be driven to move leftward along the length direction of the pivot assembly 13; when the pivot assembly 13 rotates reversely, the sliding part 42 can be driven to move rightward 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, the sliding part 42 can be driven to move forward in the radial direction of the pivot assembly 13; when the pivot assembly 13 rotates reversely, the sliding part 42 can be driven 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.

[0108] 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.

[0109] 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 part 42 is inserted into the cam groove. When the pivot assembly 13 rotates, the sliding part 42 slides in the cam groove and drives the sliding part 42 to move along the radial direction of the pivot assembly 13.

[0110] 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.

[0111] See also Figure 18-Figure 22 , Fig.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. Fig.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 slide groove 133. Fig. 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. Fig.21 This is a schematic diagram of the structure of the transmission structure 44 provided in the embodiment of the present application. Fig. 22 An exploded schematic diagram of the transmission structure 44 provided in an embodiment of the present application.

[0112] In one embodiment, see Fig.17 A slide groove 133 is provided on the circumferential side of the pivot assembly 13, one end of the sliding portion 42 is inserted into the slide groove 133 and the sliding portion 42 can slide along the length direction of the slide groove 133, see Fig.18 The slide 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 .

[0113] See also Fig.18 , which shows that one end of the sliding part 42 is inserted into the inclined groove part 1331. When the pivot assembly 13 rotates, the groove side wall of the inclined groove part 1331 along the length direction squeezes the sliding part 42 and extends into the end of the inclined groove part 1331, so that the sliding part 42 slides along the length direction of the slide groove 133, thereby realizing the movement of the sliding part 42 relative to the pivot assembly 13 along the axis direction of the pivot assembly 13. In addition, see Fig.18 , illustrating that a connecting shaft 131 of the pivot assembly 13 is supported on the shaft seat 23 on the bottom shell 212.

[0114] See also Fig.18 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. 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 arranged 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 along the circumferential direction of the pivot assembly 13 at the same time.

[0115] In one example, see Fig.18 , the projection of the inclined groove portion 1331 in the direction of the XOY plane is a straight line; or, the projection of the inclined groove portion 1331 in the direction of the XOY plane is an arc shape; or, the projection of the inclined groove portion 1331 in the direction of the XOY plane is a wave shape formed by two arcs, etc.

[0116] 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 can 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.

[0117] See also Fig.18 and Fig.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, and the inclined groove first end 13311 is sequentially arranged along the axial direction of the pivot assembly 13 and along the circumferential direction of the pivot assembly 13 relative to the inclined groove second end 13312, see Fig. 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 portion 10 is in a state of being buckled on the host portion 20, and the baffle 41 is also in a state of closing the air inlet 218. When the display portion 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 Fig.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.

[0118] In one example, one end of the sliding portion 42 extending into the sliding groove 133 is spherical or cylindrical with rounded corners.

[0119] In one example, see Fig.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.

[0120] In an example, the material of the sliding sleeve 45 is a metal material, for example, the material of the sliding sleeve 45 is copper.

[0121] 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 .

[0122] 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, when the display screen portion 10 is rotated, the sliding portion 42 can be driven to move relative to the pivot assembly 13 along the axial direction of the pivot assembly 13, and the matching structure of the transmission structure 44 and the pivot assembly 13 is simple.

[0123] In one embodiment, see Fig.19The slide groove 133 also includes a straight groove portion 1332, the straight groove portion 1332 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 a set angle, one end of the sliding portion 42 is inserted into the straight groove portion 1332.

[0124] See also Fig.19 , showing that one end of the sliding portion 42 is inserted into the straight groove portion 1332. Fig. 20 When the display screen 10 is buckled on the host 20, one end of the sliding part 42 is located at the first end 13311 of the inclined slot, and the baffle 41 closes the air inlet 218. When the display screen 10 is rotated, the sliding part 42 can move along the inclined slot 1331 toward the second end 13312 of the inclined slot, and the sliding part 42 drives the connecting part 43 to move so that the connecting part 43 drives the baffle 41 to rotate to open the air inlet 218. When the display screen 10 is opened to a set angle, see Fig.18 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 rotate and open, one end of the sliding portion 42 moves toward the straight groove portion 1332, and when the sliding portion 42 is driven by the display screen portion 10, it moves in the straight groove portion 1332 in a direction away from the second end 13312 of the inclined groove. 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 length 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.

[0125] When the display screen portion 10 is opened at an angle greater than the set angle relative to the host portion 20, one end of the sliding portion 42 is located at 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 direction close to the second end 13312 of the inclined groove. At this time, the baffle 41 does not rotate relative to the host portion 20 (that is, the opening 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 part 42 is located at the second end 13312 of the inclined groove. When the display screen part 10 continues to be rotated in the opposite direction until the display screen part 10 is buckled on the main unit 20, the sliding part 42 can move along the inclined groove part 1331 toward the first end 13311 of the inclined groove until one end of the sliding part 42 is located at the first end 13311 of the inclined groove. When the sliding part 42 moves along the inclined groove part 1331, the baffle 41 gradually rotates in the direction of closing the air inlet 218 until the display screen part 10 is buckled on the main unit 20, and the baffle 41 closes the air inlet 218.

[0126] That is to say, in the embodiment of the present application, when the sliding portion 42 slides in the inclined 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.

[0127] When using the laptop computer 100, different users open the display screen 10 at different angles according to the habits of each user. If the slide groove 133 only includes the inclined groove portion 1331, the angle of the display screen 10 in the use state will affect the opening angle of the baffle 41. Therefore, in the embodiment of the present application, the sliding portion 42 is provided to include not only the inclined groove portion 1331 but also the straight groove portion 1332, so that when the display screen 10 of the laptop computer 100 is opened from the preset angle and then rotated to open, it will not affect the opening angle of the baffle 41, so that even if the angle of the display screen 10 is different due to different habits of different users, the baffle 41 can be opened at the same angle. Of course, it is worth noting that in an example, the slide groove 133 can also be provided to include only the inclined groove portion 1331.

[0128] 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, the sliding portion 42 will not be driven to move, and the display screen portion 10 will not be rotated in the direction of being engaged with the host portion 20. Or, in other words, if the slide groove 133 only includes the inclined groove portion 1331, when the laptop computer 100 is in use, one end of the sliding portion 42 is located in the inclined 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 inclined groove portion 1331, so that the display screen portion 10 will rotate in the direction of being engaged with the host portion 20.

[0129] 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.

[0130] 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 inclined groove portion 1331, and 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°.

[0131] For example, the value range of the set angle may be 60°~65° or 65°~70° or 75°~80° or 85°~90°.

[0132] For example, when the display screen portion 10 is opened at an angle not greater than 90°, one end of the sliding portion 42 is inserted into the inclined groove portion 1331 , and when the display screen portion 10 is opened at an angle greater than 90°, one end of the sliding portion 42 is inserted into the straight groove portion 1332 .

[0133] Usually, when the notebook computer 100 is used, the opening angle of the display screen 10 is greater than 90°, so that the user can conveniently observe the content displayed on the display screen 10. Therefore, in the embodiment of the present application, the value range of the set angle is set to 60°~90°, so that even if different users have different habits and cause different opening angles of the display screen 10, the baffle 41 can be opened at the same angle.

[0134] In one embodiment, see Fig.21 The connecting portion 43 includes a fixing seat 431, a slider 432 and a connecting rod 433, see Fig.18 and Fig.19 The fixed seat 431 is fixed in the main unit 20, the slider 432 is movably connected to the fixed seat 431 and the fixed seat 431 guides the slider 432 to move, 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.

[0135] See also Fig.18 and Fig.19 The fixing seat 431 is fixed on the inner side of the bottom shell 212 of the main body 20. In one example, the fixing seat 431 is adhered to the bottom shell 212; in other examples, the fixing seat 431 is detachably connected to the bottom shell 212.

[0136] 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.

[0137] See also Fig.18 and Fig.19 The 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.

[0138] In one example, see Fig.18A slider connecting ear 4321 is provided 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 .

[0139] In one example, see Fig.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.

[0140] 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.

[0141] In one embodiment, see Fig.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 Fig.18 and Fig.19 The slider slot 4322 extends in a direction parallel to the axis of the pivot assembly 13 and in a direction from close to the baffle 41 to away from the baffle 41 .

[0142] See also Fig.18 and Fig. 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.

[0143] In one example, see Fig. 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.

[0144] See also Fig. 20When 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 along the direction indicated by the arrow facing away from 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 to move toward the baffle 41, so that the connecting rod 433 connected to the slider 432 pushes the baffle 41 to rotate in the direction of opening the air inlet 218; see Fig.18 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 one end of the sliding portion 42 slides in the straight groove portion 1332, since the sliding portion 42 does not move along the length direction of the pivot assembly 13, the slider 432 does not move relative to the fixing seat 431, and the baffle 41 does not rotate relative to the host portion 20.

[0145] See also Fig.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, and 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, thereby causing the connecting rod 433 connected to the slider 432 to pull the baffle 41 to rotate in the direction of closing the air inlet 218.

[0146] It is worth mentioning that Fig.18 It is shown 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 sliding groove. Fig. 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.

[0147] 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.

[0148] In one embodiment, see Fig.21 and Fig. 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, Fig.21 The two opposite ends of the slider 432 in the X-axis direction are in contact with the groove walls of the corresponding sides of the first guide groove 4311, and the slider 432 is in contact with the first guide groove 4311 along the direction perpendicular to the axis of the pivot assembly 13. Fig.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 .

[0149] In one example, see Fig. 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, Fig. 22 In the 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, see Fig. 22 , illustrating that both ends of the lower slider segment 4324 protrude from the end portions of the corresponding sides of the upper slider segment 4323 .

[0150] In one example, the slider 432 is an integrally formed structure.

[0151] In one example, see Fig. 22 One end of the first guide groove 4311 is connected to the end of the fixed seat 431 away from the sliding portion 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.

[0152] 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 the fixing seat 431 can guide the movement of the slider 432 , but also the connection structure between the two is simple.

[0153] In one embodiment, see Fig.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 .

[0154] In one example, see Fig. 22 The second protrusion 424 includes an upper protrusion section 4241 and a lower protrusion section 4242. The lower protrusion section 4242 is along Fig. 22 At least one of the two ends in the Y-axis direction protrudes from the end of the corresponding side of the upper raised section 4241, see Fig. 22 , showing the lower raised section 4242 along Fig. 22 The ends of the upper protrusion section 4241 protrude from the ends of the corresponding sides thereof at both ends in the 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 escaping from the fixing seat 431 upwardly along the Z-axis direction.

[0155] In one example, the second guide groove 4312 is arranged along the length direction (ie Fig. 22 At least one of the two ends (in the X-axis direction) is connected to the corresponding side of the fixing seat 431, so as to facilitate the second protrusion 424 to be inserted into the fixing seat 431 from one end of the second guide groove 4312.

[0156] In one example, see Fig. 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.

[0157] In one example, the sliding portion 42 is an integrally formed structure.

[0158] 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 .

[0159] 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 mentioning that the sliding part 42 may also be arranged not to include the second protrusion 424 and the second guide groove 4312 is not arranged 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 arranged 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 arranged 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.

[0160] The above description is about the first protrusion 423 on the sliding part 42 being 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 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 with 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 with 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.

Fig.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. Fig.26 This is a 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. Fig. 27 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.

[0162] In one embodiment, see Fig.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.

[0163] 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 with 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.

[0164] 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 respectively face 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.

[0165] 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 matching the arc concave surface is set on the baffle 41, 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.

[0166] In one embodiment, see Fig.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 .

[0167] One or more baffle grooves 413 are provided on the inner side surface of the baffle 41 , that is, one baffle groove 413 may be provided on the inner side surface of the baffle 41 , or more than two baffle grooves 413 may be provided, and the baffle grooves 413 are arranged in sequence and spaced apart along the length direction of the baffle 41 .

[0168] See also Fig.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 an arc groove surface 21241 is provided on the limiting member 2124.

[0169] See also Fig.25 and Fig.26 The first mating protrusion 414 is inserted into the arc groove surface 21241 on the limiting member 2124 and the first mating protrusion 414 is rotatably connected to the limiting member 2124. When the baffle 41 rotates, the second mating protrusion 415 rotates relative to the limiting member 2124, that is, the axis of the second mating protrusion 415 is the rotation axis of the baffle 41.

[0170] In one example, the cross section of the first mating protrusion 414 (the cross section parallel to 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.

[0171] In one example, see Fig.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.

[0172] In the embodiment of the present application, the first matching protrusion 414 is provided to match with the limiting member 2124 , so as to facilitate the baffle 41 to be stably rotatably connected to the bottom shell 212 .

[0173] In one embodiment, see Fig.25 Each baffle groove 413 is also provided with a second mating protrusion 415, see Fig. 27 , the second matching protrusion 415 extends toward the corresponding bottom shell groove 2123 .

[0174] In one example, see Fig.25 The second mating protrusion 415 is in the shape of a half cylinder, and the arc surface of the second mating protrusion 415 faces upward along the Z-axis direction.

[0175] In one example, see Fig.25 The first mating protrusions 414 are respectively provided at both ends of the second mating protrusion 415 along the X-axis direction.

[0176] In the embodiment of the present application, the first matching protrusions 414 are respectively extended to the corresponding bottom shell slots 2123 and the second matching protrusions 415 are matched with the limiting members 2124 , so that the baffle 41 can be stably rotatably connected to the bottom shell 212 .
