Description

Laptop computer

Technical Field

The present disclosure relates to electronic products, and more particularly, to a laptop computer.

Background

Laptop computers have now become an indispensable electronic product for people's work and life, and they integrate a plurality of components such as a keyboard, a motherboard, a battery, and the like, in addition to a screen. Generally, a laptop computer main body includes a first housing (upper housing) and a second housing (lower housing). The first housing (upper housing) is combined with the second housing (lower housing), and there is no relative movement between the first housing (upper housing) and the second housing (lower housing). In order to integrate these components into the main body case of a laptop computer, the prior art generally provides a support member inside the main body case for carrying the components and fixing the support member in the main body case. For example, a metal keyboard holder may be disposed inside a host casing of a laptop computer, the keyboard may be assembled on one side of the metal keyboard holder, the motherboard and other components (or what may be understood as a motherboard stacking assembly) may be assembled on the other side of the metal keyboard holder, and finally the metal keyboard holder carrying the keyboard and motherboard stacking assembly may be secured within the host casing of the laptop computer to achieve the integration of the above components. Some of the electronic components within these laptop computers often generate thermal energy during operation, which affects the operational performance of the laptop computer.

As laptop computer functions are enhanced, heating power of electronic components such as a processor and a display chip will be increased accordingly, and although the laptop computer is currently provided with a heat dissipating hole formed on a second case (lower case), the conventional heat dissipating hole cannot meet the increased heat dissipating demand. In order to increase the heat dissipation efficiency, most existing laptop computers use heat sinks such as liquid-cooled to dissipate the heat inside the housing through a thermally efficient medium, but this design complicates the product structure. Some laptop computers increase the air intake by increasing the coverage area of the ventilation apertures in the bottom shell, but this design suffers from reduced bottom shell strength. Accordingly, how to configure the heat dissipating device in an efficient structure to have better heat dissipating efficiency is a problem to be addressed by those skilled in the art.

Embodiments will now be described more fully with reference to the accompanying drawings. Embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the embodiments to those skilled in the art. In the following description, well-known functions or constructions are not described in detail since they would obscure the embodiments with unnecessary detail and the same reference numerals in the drawings represent the same or similar elements throughout the description.

Referring to fig. 1 and 2, the laptop computer according to the embodiment of the present application includes a first housing 1 provided with a display module, and a second housing 2 connected to the first housing 1 through at least one hinge assembly 3, and the second housing 2 can accommodate a main board, a keyboard, a communication interface, and the like. The first casing 1 and the second casing 2 form the external appearance of the laptop computer and may be made of metal or plastic material. Further, the laptop computer may have a substantially rectangular parallelepiped shape, but is not limited thereto. The material, size and shape of the first housing 1 or the second housing 2 may be formed in various ways. When the first casing 1 is in the initial state, the first casing 1 and the second casing 2 are in the stacked state; when the first housing 1 is in use, the first housing 1 is turned to an angle (e.g. 90-120 degrees) with the second housing 2. Wherein the rotating shaft assembly 3 is connected with the first shell 1 through the first connecting plate 4, and the rotating shaft assembly 3 is connected with the second shell 2 through the second connecting plate 7.

In an embodiment of the present application, the spindle assembly 3 may comprise a first spindle assembly 3 and a second spindle assembly (not shown in the figures), wherein the first spindle assembly 3 is connected to a transmission structure. The other end of the transmission structure is connected with the air inlet cover plate 8, when the first shell 1 rotates from an initial state to a use state, the first shell 1 drives the first rotating shaft assembly 3 to rotate, the first rotating shaft assembly 3 rotates to drive the transmission structure, and the transmission structure drives the air inlet cover plate 8 to move. Since the first casing 1 is internally provided with the display module, the first casing 1 having the display module may also be referred to as a display module, a display end, or the like in the following embodiments. Similarly, since the second housing 2 is internally provided with a motherboard, a keyboard, a memory of a device system, and the like, the second housing 2 provided with the motherboard may also be referred to as a host, a system side, and the like in the following embodiments.

The air inlet only has an air inlet function, and the air inlet function is needed when the laptop computer is in a use state. That is, when the laptop is in an unused state, the air inlet function is not needed, and the air inlet can be closed, so that the air inlet is not always exposed to the outside to influence the overall visual effect of the laptop. Based on this, the air inlet cover plate 8 is arranged at the position of the air inlet, the air inlet cover plate 8 can cover the air inlet when the laptop is not in use, and the air inlet cover plate 8 can move to open the air inlet when the laptop is in use.

In particular, in an advantageous embodiment of the application, the transmission structure comprises a gear wheel 5 fitted over the first shaft assembly 3, and a rack 6 connected to the gear wheel 5. Wherein the air inlet cover plate 8 is connected with the rack 6. The air inlet cover plate 8 is used to prevent dust from the air inlet of the fan from entering the interior of the laptop when the display end of the laptop is closed. The air inlet cover plate 8 is driven by the rack 6, and the opening and closing process of the display end of the laptop is related to the action of the air inlet cover plate 8 through the gear 5 and the rack 6. In the process that the display end of the laptop is closed relative to the system end, the display end drives the gear 5 and the rack 6 to drive the air inlet cover plate 8 to seal the air inlet; in the process of opening the display end of the laptop relative to the system end, the display end drives the gear 5 and the rack 6 to drive the air inlet cover plate 8 to open the air inlet.

Thus, the opening and closing of the air inlet of the laptop computer is controlled by the air inlet cover plate 8, namely when the display end is opened, the laptop computer is in a use state, the air inlet cover plate 8 is far away from the air inlet, and the air inlet is opened to increase the air inlet quantity; when the display end is closed, the laptop is in an initial state, the air inlet cover plate 8 seals the air inlet, so that dust is effectively prevented from entering the interior from the air inlet, and the service life of internal components is prolonged.

The rack 6 is further configured such that when the first housing 1 is moved from the initial state to the use state, the rack 6 can drive the air inlet cover 8 to move to open the air inlet. Thus, when a user opens the display screen to use the laptop, the heat generated by the main board can be cooled by the air entering from the air inlet. Correspondingly, when the air inlet cover plate 8 moves from the use state to the initial state along the guide rail 9, the air inlet cover plate 8 moves from being separated from the air inlet to covering the air inlet, so that the air inlet is closed. Therefore, when the display screen is buckled, the first casing 1 is in an initial state, and the air inlet is not exposed.

The manner in which the guide rail 9 of the laptop computer is connected to the second casing 2 is also non-limiting, as long as the guide rail 9 can be fastened to the second casing 2. For example, the guide rail 9 may be connected to the second housing 2 by welding or bonding, or the guide rail 9 may be connected to the second housing 2 by a snap-fit connection. The second housing 2 may also be provided with a mounting plate, on which the guide rail 9 may be fixed. In other embodiments, the guide rail 9 may be detachably connected to the second housing 2, so that the guide rail 9 may be detached for subsequent maintenance or replacement.

In the preferred embodiment of the application, two mutually parallel guide rails 9 are arranged at two ends of the air inlet cover plate 8, the two guide rails 9 comprise a first guide rail close to the rack 6 and a second guide rail 9 far away from the rack 6, two ends of the air inlet cover plate 8 extend in a first direction and are respectively connected with the first guide rail and the second guide rail, and the air inlet cover plate 8 penetrates through the first guide rail in the first direction to be connected with the rack 6. The air inlet cover plate 8 is in transmission connection with the first rotating shaft assembly 3 through the rack 6. In this way, the first rotating shaft assembly 3 can drive the air inlet cover plate 8 to move in the second direction so as to open or close the air inlet. Wherein the first direction and the second direction may be 90 degrees to each other. The air inlet cover plate 8 can cover the air inlet arranged in the second shell. The rack 6, the first guide rail, the second guide rail and the air inlet cover plate 8 are all configured to be arranged parallel to the direction of the second shell 2, and the air inlet cover plate 8 penetrates through the first guide rail to be connected with the rack 6.

The connection structure of the air inlet cover plate 8 and the guide rail 9 will be described in detail below by taking the connection of the air inlet cover plate 8 and the first guide rail as an example. It should be understood that the structure provided at the first rail may also be provided symmetrically on the second rail for the same purpose.

Referring to fig. 3 to 7, wherein the intake cover 8 is provided with a first protruding unit 10 and a second protruding unit 11 toward the first rail, the first protruding unit 10 and the second protruding unit 11 are respectively configured to abut against a first portion of the first rail and a second portion of the first rail in the second direction. Wherein a first portion of the first rail is adjacent to one end of the inlet cover plate 8; the second portion of the first rail is adjacent the other end of the inlet cover 8. I.e. the first protruding unit 10 and the second protruding unit 11 may be arranged at both ends of the intake cover plate 8 in the second direction.

The first guide rail may be configured such that a third projection unit 12 and a fourth projection unit 13 are provided towards the intake cover 8. When the air inlet cover plate 8 covers the air inlet, the third protruding unit 12 is abutted against the first protruding unit 10, and the fourth protruding unit 13 is abutted against the second protruding unit 11. The first protruding unit 10, the second protruding unit 11, the third protruding unit 12 and the fourth protruding unit 13 are all provided with rectangular matching surfaces, namely when the air inlet cover plate 8 covers the air inlet, the third protruding unit 12 and the first protruding unit 10 are abutted together through a plane, and the fourth protruding unit 13 and the second protruding unit 11 are abutted together through a plane.

The first, second, third and fourth projection units 10, 11, 12 and 13 are provided with inclined transition surfaces, and the inclination angles of the four transition surfaces are the same. As shown in fig. 6, the first projection unit 10 is formed with a transition surface of β, and the third projection unit 12 is formed with a transition surface of α, where β=α. Similarly, the second projection unit 11 is formed with a transition surface of α, and the fourth projection unit 13 is formed with a transition surface of β, where α=β.

After the air inlet cover plate 8 with the same height of the first protruding unit 10, the second protruding unit 11, the third protruding unit 12 and the fourth protruding unit 13 starts to move along the second direction, the four protruding units are abutted from a plane to an inclined transition plane; referring to fig. 7, when the inlet cover 8 moves more than four protruding units in the second direction, the first protruding unit 10 and the second protruding unit 11 may abut against the guide rail 9 because the protruding units are the same in height. The third protruding unit 12 and the fourth protruding unit 13 may be in contact with the air inlet cover 8 in the same manner.

Referring to fig. 8 and 9, the first and second projection units 10 and 11 are spaced apart a predetermined distance in a first direction, which is different from the moving direction of the intake cover 8. The third projection unit 12 and the fourth projection unit 13 are also disposed at a predetermined distance in the first direction. This arrangement makes it possible that the first projection unit 10 and the second projection unit 11 do not interfere with each other, i.e., the first projection unit 10 is not interfered by the fourth projection unit 13 when it moves in the second direction to the vicinity of the fourth projection unit 13. This arrangement allows the mechanical structure to operate more smoothly. Wherein the predetermined distance may be 0.5mm.

Referring to fig. 10 to 15, in other preferred embodiments of the application, the face of the intake cover 8 facing the second housing 2 is provided with a first plane and a second plane, the first plane being configured to cover the intake when the first housing 1 is in the initial position; the second plane is configured to abut against the second housing 2 when the first housing 1 is in the initial position. Wherein the first plane is lower than the second plane, and a height difference between the first plane and the second plane may be equal to a thickness of the second housing 2, the first plane being flush with a lower surface of the second housing 2 when the first housing 1 is in the initial position.

An inclined plane is provided between the first plane and the second plane, the inclination angle of the inclined plane may be set to θ, the second housing 2 may also be provided with an inclined plane, and the angle of the inclined plane is set to μ, where θ=μ. And the inclination direction of the inclined plane between the first plane and the second plane is the same as the inclination direction of the inclined plane of the second shell 2. When the air intake cover 8 is moved, the first plane is smoothly brought into contact with the upper surface of the second housing 2 from flush with the lower surface of the second housing 2 by the inclined surface, so that the air intake cover 8 can move along the gap between the second housing 2 and the fan 14. In order to avoid interference, the distance between the intake cover 8 and the fan 14 should be equal to or greater than the thickness of the second housing 2 when the first housing 1 is in the initial position.

With reference to fig. 16 and 17, in other preferred embodiments of the present application, the length of the inlet cover 8 may be optimized, for example, the difference between the length of the guide rail 9 and the length of the inlet cover 8 (R in the figure) should be greater than the length of the inlet (Q in the figure).

It is to be understood that the embodiments described herein should be considered in descriptive sense only and not for purposes of limitation. The description of features or aspects within each implementation side should generally be considered to be applicable to other similar features or aspects in other embodiments. Although one or more embodiments have been described with reference to the accompanying drawings, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope as defined by the following claims.
