Description

Technical Field

[0001] This invention relates to the field of notebook computer technology, and more specifically to a notebook computer with a separate heat dissipation air inlet and heat dissipation air outlet. Background Technology

[0002] A laptop computer, or simply a notebook, is a small and lightweight electronic device. It is characterized by its compact size and portability, and is widely used in our daily work and life.

[0003] Typically, laptop cooling vents are located near the hinge between the chassis and the display, while cooling vents are located at the bottom of the chassis. During operation, cool air is drawn into the chassis through the cooling vents at the bottom by the cooling fan. After heat exchange within the chassis, the hot air is expelled from the cooling vents at the hinge, thus achieving the laptop's cooling function.

[0004] However, this setup has the following disadvantages: (1) The heat dissipation air inlet is located at the bottom of the chassis. When using a laptop, the bottom of the chassis is in contact with the desktop, and the desktop will block part of the heat dissipation air inlet, hindering the entry of cold air and affecting the heat dissipation effect; (2) Since the heat dissipation air inlet and the heat dissipation air outlet are located very close to each other, the hot air discharged from the heat dissipation air outlet can easily flow back to the heat dissipation air inlet at the bottom of the chassis under the action of the cooling fan, and then re-enter the chassis, further affecting the heat dissipation effect of the laptop. The electronic components inside the chassis are in a high-temperature state for a long time, which is easy to damage and affects the service life of the laptop. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defects of the prior art in which hot air from a laptop can easily flow back into the body, resulting in poor heat dissipation and affecting the lifespan of the laptop. The present invention provides a laptop with a separate heat dissipation inlet and outlet that can effectively prevent hot air backflow, provide good heat dissipation, and ensure the lifespan of the laptop.

[0006] To address the aforementioned problems, the present invention provides a laptop computer with a separated heat dissipation air inlet and outlet, comprising a display screen and a chassis hinged together. The chassis is provided with a heat dissipation air inlet and an air dissipation air outlet, and further includes a separating mechanism. The separating mechanism includes a separating component, at least one set of rotating components, and at least one set of hinge components. The rotating components are fixedly connected to the display screen, the upper part of the hinge components is fixedly connected to the chassis, and the separating component is disposed at the lower part of the hinge components. The rotating components drive the hinge components to open and close, and the separating component is located between the heat dissipation air inlet and the air dissipation air outlet.

[0007] Preferably, the rotating component engages with the hinge component for transmission.

[0008] Preferably, the rotating assembly includes a rotating shaft and a first gear. The rotating shaft includes a display screen mounting part, which is fixedly connected to the display screen. The first gear rotates coaxially with the rotating shaft.

[0009] Preferably, the rotating shaft further includes a first gear mounting portion, wherein the first gear is fixedly mounted in the first gear mounting portion.

[0010] Preferably, the hinge assembly includes a second gear, a connecting frame, and a rotating frame. The axle of the second gear is parallel to and connected to the rotating shaft. The second gear meshes with the first gear. The second gear and the rotating frame have a sliding opening and closing structure. The connecting frame is fixedly connected to the machine body. The connecting frame and the rotating frame are hinged at the ends away from the rotating shaft. The separating component is disposed at the lower part of the rotating frame.

[0011] Preferably, the rotating frame includes two identical rotating sub-frames, which are respectively disposed on both sides of the first gear and the second gear. The connecting frame includes two identical connecting sub-frames, which are respectively disposed on the outer side of the two rotating sub-frames. The rotating sub-frames and connecting sub-frames on the same side are hinged at the end away from the rotating shaft, and the other end of the connecting sub-frame is rotatably connected to the rotating shaft.

[0012] Preferably, the sliding opening and closing structure includes a slide groove and a slide rod. The slide groove is formed on the rotating bracket, and the slide rod is disposed on the extension of the second gear. The slide rod is adapted to slide within the slide groove.

[0013] Preferably, the groove has an arc-shaped structure.

[0014] Preferably, the separating component is a partition, and the upper surface of the partition is fixedly connected to the rotating frame.

[0015] Preferably, a foot pad is fixed on the lower surface of the partition.

[0016] The present invention has the following advantages:

[0017] 1. The laptop computer provided by this invention, which separates the heat dissipation air inlet and outlet, has a separating component between the heat dissipation air inlet and outlet at the bottom of the chassis. The separating component can be opened by the hinge assembly, thereby separating the heat dissipation air inlet and outlet and preventing hot air discharged from the outlet from re-entering the chassis through the heat dissipation air inlet, thus improving the heat dissipation effect of the laptop computer. At the same time, the opened separating component can lift the chassis, so that the bottom of the chassis is supported and a height difference is formed between it and the desktop. The desktop no longer blocks the heat dissipation air inlet, and cool air can enter the chassis more effectively from the heat dissipation air inlet, thereby improving the heat dissipation effect of the laptop computer and ensuring the service life of the laptop computer.

[0018] 2. The laptop computer with a separate heat dissipation air inlet and outlet provided by the present invention has a simple and reliable transmission structure between the rotating component fixed on the display screen and the hinge component fixed on the body. This transmission structure can open the separating component at the same time as the laptop screen is opened, thereby separating the heat dissipation air inlet and outlet of the laptop and supporting the body for convenient use.

[0019] 3. The laptop computer with a separate heat dissipation air inlet and heat dissipation air outlet provided by the present invention has a sliding opening and closing structure with an arc-shaped groove, which allows the partition to open more smoothly.

[0020] 4. The laptop computer with a separate heat dissipation air inlet and outlet provided by the present invention also has feet fixedly installed on the lower surface of the partition, which can increase the sliding friction between the partition and the table, thereby making the laptop computer more firmly placed on the table and preventing it from sliding at will.

[0047] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] Example 1

[0049] like Figure 1 , 4 Figure 5 shows a preferred embodiment of the laptop computer with a separate heat dissipation air inlet and heat dissipation air outlet according to the present invention.

[0050] The laptop computer in this embodiment includes a display screen 200 and a chassis 100 that are hinged together, such as... Figure 1 , 2 As shown in Figure 3, the body 100 is provided with a heat dissipation air inlet 1002 and a heat dissipation air outlet 1003, wherein the heat dissipation air inlet 1002 is located at the bottom of the body 100, and the heat dissipation air outlet 1003 is located at the hinge position between the body 100 and the display screen 200.

[0051] The laptop computer in this embodiment also includes a separation mechanism for separating the heat dissipation air inlet 1002 and the heat dissipation air outlet 1003, preventing the hot air discharged from the heat dissipation air outlet 1003 from re-entering the chassis through the heat dissipation air inlet 1002, thereby improving the heat dissipation effect of the laptop computer.

[0052] The partition mechanism includes a partition component, at least one set of rotating components, and at least one set of hinge components. The rotating components and hinge components cooperate with each other, and the rotating components can drive the hinge components to open and close through meshing transmission. In this embodiment, two sets of rotating components and two sets of hinge components are used, and the two sets of rotating components are respectively arranged on both sides of the laptop. Similarly, the two sets of hinge components are also respectively arranged on both sides of the laptop, and the rotating components and hinge components on the same side cooperate with each other.

[0053] The rotating component is fixedly connected to the display screen 200, and the opening and closing of the display screen 200 synchronously drives the rotating component. The upper part of the hinge component is fixed to the body 100, and the dividing component is fixed to the lower part of the hinge component. The length direction of the dividing component is parallel to the axis of the hinge between the body 100 and the display screen 200. The dividing component is further positioned between the heat dissipation air inlet 1002 and the heat dissipation air outlet 1003. The length of the dividing component can be set according to the body size and the positions of the heat dissipation air inlet 1002 and the heat dissipation air outlet 1003, as long as it can separate the heat dissipation air inlet 1002 and the heat dissipation air outlet 1003.

[0054] When the hinge assembly is closed, the partition component is attached to the bottom of the chassis 100. The hinge assembly opens under the rotation of the rotating assembly, and at the same time, the partition component also rotates and opens relative to the chassis 100. The partition component and the chassis 100 have a certain angle. The partition component can lift the chassis 100, so that a certain height difference is formed between the bottom of the chassis 100 and the desktop. At this time, the cool air can enter the chassis 100 smoothly through the heat dissipation air intake 1002, thereby improving the heat dissipation effect of the laptop and ensuring the service life of the laptop.

[0055] Specifically, the rotating assembly includes a rotating shaft 1 and a first gear 2. Wherein, as... Figure 6 As shown, the rotating shaft 1 has a first gear mounting part 101 and a display screen mounting part 103. The first gear 2 is fixedly mounted on the first gear mounting part 101, realizing coaxial rotation between the first gear 2 and the rotating shaft 1. The display screen mounting part 103 has a plurality of display screen mounting holes 104 and display screen positioning holes 105. In this embodiment, the display screen mounting part 103 has three circular display screen mounting holes 104, and the centers of the three display screen mounting holes 104 are not on a straight line, for use with screws and other connecting parts to be mounted on the display screen 200; the display screen mounting part 103 has two circular display screen positioning holes 105, which facilitates the positioning and installation between the rotating shaft 1 and the display screen 200. In this embodiment, the first gear 2 is a circular spur gear.

[0056] The rotating shaft 1 also has a limiting part 102, such as Figure 11As shown, the limiting member 8 is sleeved on the limiting part 102 through the rotating shaft mounting part 801, and the limiting member 8 is rotatably connected to the rotating shaft 1. The rotating shaft 1 can rotate in the limiting member 8. The limiting member 8 also has a limiting rib 802. The limiting member 8 is fixedly connected to the hinge assembly through the limiting rib 802, so as to realize the limiting between the hinge assembly and the limiting member 8, and better prevent the hinge assembly from moving.

[0057] The hinge assembly includes a second gear 3, a connecting frame 6, and a rotating frame 4. The axis of the second gear 3 is parallel to the rotating shaft 1, and the second gear 3 is connected to the rotating shaft 1. In this embodiment, the second gear 3 is connected to the rotating shaft 1 via positioning members 7 connected to both sides of the first gear 2. The second gear 3 meshes with the first gear 2 for transmission.

[0058] like Figure 10 As shown, the inner side of the positioning member 7 has a connecting frame mounting portion 701 and a second gear mounting portion 703. The connecting frame mounting portion 701 also has a connecting frame mounting rib 702 for fixed connection with the connecting frame 6. In this embodiment, the connecting frame mounting rib 702 is a curved protruding rib, suitable for cooperating with the rotating shaft 1.

[0059] like Figure 7 As shown, the second gear 3 has an extension 301 and a driven rib 303. The extension 301 has slide rods 302 at both ends. The second gear 3 is rotatably connected to the second gear mounting part 703 through the driven rib 303, so that the second gear 3 can rotate in the positioning member 7. The second gear 3 and the rotating frame 4 have a sliding opening and closing structure. When the second gear 3 rotates, the slide rod 302 also performs a circular motion, so that the slide rod 302 slides in the rotating frame 4, so that the angle of the rotating frame 4 can change.

[0060] In this embodiment, the second gear 3 is a circular spur gear, and the second gear 3 has teeth that are distributed circumferentially.

[0061] like Figure 8 As shown, the rotating frame 4 consists of two parallel rotating sub-frames 401 and a base plate connecting the two rotating sub-frames 401. One end face of the rotating sub-frame 401 near the rotating shaft 1 has a groove 402. The groove 402 and the slide rod 302 together form a sliding opening and closing structure, and the slide rod 302 is adapted to slide within the groove 402. In this embodiment, the groove 402 is an arc-shaped structure, and the length of the arc-shaped groove 402 meets the opening angle requirements of the laptop screen 200 during normal use. Simultaneously, the arc-shaped groove 402 allows for smoother rotation of the rotating frame 4. The other end of the rotating sub-frame 401 away from the rotating shaft 1 has a rotating rib 403. The rotating frame 4 is hinged to the connecting frame 6 via the rotating rib 403. The separating component is fixedly installed at the bottom of the base plate of the rotating frame 4. The opening and closing of the rotating frame 4 drives the separating component to open and close.

[0062] The partition is a partition 5. The upper surface of the partition 5 is fixed to the bottom of the base plate of the rotating frame 4. The lower surface of the partition 5 is also fixedly installed with a foot pad 9, which can increase the sliding friction between the partition 5 and the desktop and prevent the laptop from sliding randomly.

[0063] In this embodiment, the partition 5 is made of a rigid material, such as plastic.

[0064] like Figure 9 As shown, the connecting frame 6 consists of two connecting sub-frames 604, which are arranged opposite to each other. Each connecting sub-frame 604 has a body fixing part 602 for connecting to the mounting base 1001 of the body 100. In this embodiment, the body fixing part 602 has two circular body connecting holes 606 and one circular body positioning hole 607. The body connecting holes 606 can be fitted with screws or other connecting parts to be installed on the mounting base 1001 at the bottom of the body 100. One end of the connecting sub-frame 604 has a mounting hole 601 for connecting to the rotating shaft 1. In this embodiment, the mounting hole 601 is sleeved on both sides of the positioning member 7. The connecting sub-frame 604 also has a limiting hole 605 near the mounting hole 601 for inserting and engaging with the limiting rib 802 of the limiting member 8 to achieve a fixed connection. In this embodiment, the limiting hole 605 is a square through hole. The other end of the connecting bracket 604 has a rotating hole 603 for rotating connection with the rotating rib 403, thereby realizing the hinge between the rotating bracket 4 and the connecting bracket 6.

[0065] The opening and closing process of the laptop computer in this embodiment is described below:

[0066] When it is necessary to open the laptop screen, the laptop screen 200 is opened, and the screen mounting part 103, which is fixedly connected to the screen 200, drives the pivot 1 to rotate clockwise. Figure 4(Angle), the rotating shaft 1 drives the first gear 2 to rotate clockwise, and the second gear 3, which meshes with the first gear 2, rotates counterclockwise. The slide rod 302 will slide counterclockwise in the slide groove 402. The slide rod 302 provides a downward component force on the arc-shaped slide groove 402, thereby driving the rotating frame 4 to rotate clockwise at the end of the connecting frame 6. Finally, it drives the partition 5, which is fixedly installed at the bottom of the rotating frame 4, to rotate clockwise, so that the partition 5 is separated from the body 100 at a certain angle. During the continued flipping of the display screen 200, the slide rod 302 continues to slide in the arc-shaped slide groove 402. When the slide rod 302... After sliding to the apex of the arc-shaped slide 402, the arc-shaped slide 402 and the slide bar 302 follow the same circular motion trajectory. The slide bar 302 no longer provides downward force to the arc-shaped slide 402. At this time, the partition 5 reaches its maximum rotation angle and no longer rotates with the rotation of the display screen 200. Ultimately, the partition 5 can be automatically opened when the laptop display screen 200 is opened, separating the heat dissipation air inlet 1002 and the heat dissipation air outlet 1003. This facilitates user use while improving the heat dissipation effect of the laptop and ensuring the lifespan of the laptop.

[0067] When the laptop screen needs to be turned off, the screen 200 is closed. The screen mounting part 103, which is fixedly connected to the screen 200, drives the rotating shaft 1 to rotate counterclockwise. The rotating shaft 1 drives the first gear 2 to rotate counterclockwise, and the second gear 3, which meshes with the first gear 2, rotates clockwise. The slide bar 302 will rotate clockwise in the slide groove 402. The slide bar 302 first slides along the track of the slide groove 402. When the slide bar 302 slides to the highest point of the slide groove 402, the slide bar 302 provides an upward component force on the slide groove 402, thereby driving the rotating frame 4 to rotate counterclockwise at the end of the connecting frame 6. Finally, it drives the partition 5, which is fixedly installed at the bottom of the rotating frame 4, to rotate counterclockwise, thereby closing the partition 5 at the bottom of the chassis 100 until the screen 200 is completely closed and the partition 5 is completely attached to the bottom of the chassis 100.

[0068] Furthermore, since the end of the rotating shaft 1 has a washer that provides torque (this washer is existing technology and will not be described in detail here), the rotating shaft 1 will not rotate during normal use due to the torque provided by the washer. Therefore, the display screen 200 and the partition 5 will not be closed due to the weight of the body 100 or pressing the body 100 during normal use. That is, the partition 5 will not close during normal use after it is opened.

[0069] The laptop computer with a separate heat dissipation air inlet and outlet provided by the present invention allows adjustment of the opening angle of the partition 5 by adjusting the distance between the slider 302 and the driven rib 303. For example, increasing the distance between the slider 302 and the driven rib 303 correspondingly increases the length of the sliding groove 402 that cooperates with the slider 302, thereby increasing the opening angle of the partition 5 and thus increasing the distance between the chassis 100 and the desktop; conversely, decreasing the opening angle of the partition 5 decreases the distance between the chassis 100 and the desktop.

[0070] Example 2

[0071] The difference between the laptop computer with separate heat dissipation air inlet and outlet in this embodiment and the first embodiment is that, in order to simplify the structure, the limiting member 8 can be removed, and the corresponding limiting hole 605 can also be removed, while still ensuring the position of the connecting bracket 6 is limited, which is convenient for installation.

[0072] Example 3

[0073] The difference between the laptop computer with separate heat dissipation air inlet and outlet in this embodiment and the first embodiment is that: if the smoothness of opening the display screen 200 and the partition 5 is not required, a set of rotating components and hinge components can be used to simplify the structure and save costs, as long as the normal operation of the mechanism is ensured.

[0074] Example 4

[0075] The difference between the laptop with separate heat dissipation inlet and outlet in this embodiment and the laptop in embodiment one is that if the anti-slip requirements of the laptop are low, the feet 9 can be omitted to simplify the structure and save costs.

[0076] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
