Description

Technical Field

[0001] This invention relates to a recessed laptop, and more particularly to a recessed laptop with an opening in the screen that corresponds to a rear hole when the screen is unfolded. Background Technology

[0002] The recessed hinge is a common hinge design used in laptop screens. Its hinge mechanism is located at the bottom of the keyboard. When the user unfolds the screen, one end of the screen will sink down into the back of the laptop and support the main body. This design not only provides a better visual experience, but also makes the laptop body more compact and beautiful.

[0003] However, when the screen of a known recessed hinge design is unfolded, it obstructs the ventilation holes or connection ports at the rear. If the ventilation holes are obstructed, heat will concentrate between the screen and the main unit, affecting the laptop's heat dissipation performance. If the connection ports are obstructed, they will be unable to connect. To solve these problems, the positions of the ventilation holes and connection ports need to be reconfigured to ensure that the laptop maintains good heat dissipation and connectivity during operation. However, this also limits the heat dissipation and connection port design of recessed hinge laptops, further leading the industry to abandon the launch of laptops using recessed hinge screens. Summary of the Invention

[0004] One object of the present invention is to provide a recessed laptop, which is connected by a connecting component to a first casing, a cover plate and a second casing. The second casing has an opening. When the second casing is rotated and unfolded, the connecting component causes the cover plate to rotate away from the opening of the second casing, so that the opening of the second casing corresponds to the hole in the first casing.

[0005] To achieve the aforementioned objectives and effects, the present invention provides a recessed laptop with a heat dissipation structure comprising: a first housing, a connecting component, a second housing, a cover plate, and a housing positioning component. The first housing has a hole on one side. The connecting component is disposed on the first housing. A bottom surface of the second housing is fixed to a top surface of the connecting component. The second housing has an opening. The cover plate is disposed on top of the second housing and covers the opening. A cover plate extension extends downward from a bottom surface of the cover plate. A pivot hole is provided on one side of the cover plate extension, pivotally connecting the connecting component. A cover slide rod is provided adjacent to one side of the first housing. One side of the housing positioning member is fixed to the bottom surface of the second housing. The other side of the housing positioning member, which is perpendicular to a normal, is provided with a housing slide groove. The cover slide rod slides in the housing slide groove. The first housing is pivotally connected to the second housing through the connecting component. When the second housing rotates relative to the first housing through the connecting component and the opening aligns with the hole, the connecting component and the housing positioning member move the cover plate together, causing the cover plate to rotate and protrude from the opening. This structure provides an opening for the screen and, when unfolded, can correspond to the recessed design of the laptop with the hole at the rear.

[0006] In one embodiment of the present invention, the connecting assembly includes a shaft, a support frame, a first gear, a second positioning member, a second gear, and a third gear. One side of the shaft is fixed to one side of a first connecting portion of the first housing. The shaft passes through and pivotally connects to a bottom of the support frame. One side of the first positioning member is fixed to one side of the support frame. The shaft passes through and pivotally connects to a bottom of the first positioning member. One side of the first gear is adjacent to the other side of the first positioning member and fixed to the other side of the shaft. The first gear includes a first gear body and a tooth. The second positioning member is adjacent to the other side of the first gear. The shaft passes through and pivotally connects to a bottom of the second positioning member. The second gear is disposed between the first positioning member and the second positioning member and meshes with the tooth of the first gear. The third gear is disposed between the first positioning member and the second positioning member and meshes with the second gear.

[0007] In one embodiment of the present invention, the second positioning member includes a positioning body, a second positioning member groove, a first pivot rod, and a second pivot rod. The second positioning member groove passes through one side of the positioning body, one side of the first pivot rod and one side of the second pivot rod are fixed to the same side of the positioning body, and the other side of the first pivot rod and the other side of the second pivot rod are fixed to the other side of the first positioning member.

[0008] In one embodiment of the present invention, the second gear includes a second gear pivot hole, and the first pivot rod is pivotally connected to the second gear pivot hole.

[0009] In one embodiment of the present invention, the third gear includes a third gear pivot hole, the second pivot rod is pivotally connected to the third gear pivot hole, an extension member extends from one side of the third gear, a third gear slide rod is provided on one side of the extension member, the third gear slide rod is correspondingly slidably disposed in the slide groove of the second positioning member, a third pivot rod is provided adjacent to the third gear slide rod on the side of the extension member, and the pivot hole of the cover plate is pivotally connected to the third pivot rod.

[0010] In one embodiment of the present invention, when the second housing rotates relative to the shaft via the support frame, the first positioning member and the second positioning member rotate relative to the shaft. The first gear is fixed to the shaft and drives the second gear to rotate. The second gear rotates on the first pivot rod and drives the third gear to rotate on the second pivot rod. The third gear slide rod slides in the groove of the second positioning member. The extension member and the third pivot rod push the cover plate extension member. The cover plate extension member drives the cover plate slide rod to slide in the housing groove, and causes the cover plate to protrude from the opening and move to one side of the opening.

[0011] In one embodiment of the present invention, when the second housing rotates relative to the shaft via the support frame, the first positioning member and the second positioning member rotate relative to the shaft, and the second gear rotates relative to the shaft. The second gear rotates on the first pivot rod and drives the third gear to rotate on the second pivot rod. The third gear slide rod slides in the slide groove of the second positioning member, and the cover plate slide rod slides in the slide groove of the housing, so that the cover plate retracts the opening.

[0012] In one embodiment of the present invention, a magnetic suction member is provided on the bottom surface of the cover plate. When the cover plate is fully retracted into the second housing, the cover plate is attracted to the side of the second housing through the magnetic suction member corresponding to the opening.

[0013] In one embodiment of the present invention, the hole communicates with an inner side of the first housing.

[0014] In one embodiment of the present invention, the cover plate protrudes from the opening and moves to the side of the second housing, so that a heat flow from the first housing flows out through the hole to the opening.

[0015] In one embodiment of the present invention, the hole is further provided with a connection port.

[0016] The beneficial effects of the present invention are that it provides a recessed laptop in which, when the second casing is rotated open relative to the hinge, the cover plate protrudes outward from the second casing via a connecting component, further aligning the heat dissipation holes of the first casing with the opening of the second casing and dissipating heat flow. This solves the problem that, when a known recessed laptop is opened, the screen blocks the heat dissipation holes behind the host, causing heat flow to concentrate between the screen and the host, thereby damaging the electronic components inside the host. It also solves the problem that, when a known recessed laptop is opened, the screen blocks the connection ports behind the host. Attached Figure Description

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0061] The accompanying drawings illustrate layer structure diagrams according to embodiments of this application. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0062] Obviously, the described embodiments are only some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without any innovative effort are within the scope of protection of this application.

[0063] In the description of this application, it should be noted that the terms "first", "second", and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0064] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0065] The disadvantage of using a recessed hinge design in laptops is that when the screen is open, it blocks the ventilation holes or connection ports at the back of the main unit. This reduces the heat dissipation of the main unit, causing heat to accumulate between the screen and the main unit, which can damage the electronic components inside the main unit. At the same time, blocking connection ports limits the design scope of the laptop.

[0066] In view of the problems of the above-mentioned prior art, the present invention provides a recessed laptop, which connects a first casing, a cover plate and a second casing through a connecting component. When the second casing is rotated open in relation to the first casing, the cover plate protrudes from the opening of the second casing, so that the opening of the second casing corresponds to the position of the hole in the first casing, thereby solving the problem of the second casing blocking the hole in the first casing when the second casing is opened.

[0067] Please see Figure 1A and Figure 1B , Figure 1A This is an exploded view of the structure of one embodiment of the present invention. Figure 1B The figure shows a schematic diagram of an embodiment of the present invention. This embodiment is the first embodiment, which is a recessed laptop 1. The recessed laptop 1 includes: a first housing 10, a connecting component 20, a second housing 30, a cover plate 40, and a housing positioning component 50.

[0068] Continuing from the above, in this embodiment, a hole 14 is provided on one side of the first housing 10, and the connecting component 20 is disposed on the same side of the first housing 10, adjacent to the hole 14. A bottom surface of the second housing 30 is fixed to a top surface of the connecting component 20. The connecting component 20 connects the first housing 10 and the second housing 30. The second housing 30 also has an opening 32. A cover plate 40 is disposed on the top surface of the second housing 30 and covers the opening 32. A bottom surface of the cover plate 40 extends downward to provide a... The cover plate extension 42 has a pivot hole 421 on one side, which is pivotally connected to the connecting assembly 20. A cover plate slide rod 423 is provided adjacent to one side of the pivot hole 421. One side of the housing positioning member 50 is fixed to the bottom surface of the second housing 30. A housing slide groove 52 is provided on the other side of the housing positioning member 50, which is perpendicular to a normal. The cover plate slide rod 423 of the cover plate extension 42 passes through the housing slide groove 52, so that the cover plate slide rod 423 slides in the housing slide groove 52.

[0069] Continuing from the above, in this embodiment, the first housing 10 is pivotally connected to the second housing 30 via the connecting component 20. When the second housing 30 rotates relative to the first housing 10 via the connecting component 20 and the opening 32 aligns with the hole 14, the connecting component 20 and the housing positioning member 50 move the cover plate 40 together, causing the cover plate 40 to rotate and protrude from the opening 32, so that the opening 32 communicates with the hole 14.

[0070] In one embodiment, the first casing 10 is the main casing of a laptop computer, and the second casing 30 is the screen casing of a laptop computer.

[0071] In one embodiment, the housing slide groove 52 is arc-shaped, and its shape allows the cover plate 40 to protrude from the opening 32 or close the opening 32 when the cover plate slide rod 423 slides in the housing slide groove 52.

[0072] See again Figure 1A and Figure 1B And see Figures 2A to 2C , Figures 3A to 3D , Figures 2A to 2C This is a schematic diagram illustrating the operation of an embodiment of the present invention. Figures 3A to 3D This is a schematic diagram of the usage state of an embodiment of the present invention. This embodiment is a second embodiment, which is based on the first embodiment described above. In this embodiment, the connecting component 20 further includes: a shaft 200, a support frame 210, a first positioning member 220, a first gear 230, a second positioning member 240, a second gear 250, and a third gear 260.

[0073] Continuing from the above, in this embodiment, a first connecting portion 12 is provided on the side of the first housing 10. The first connecting portion 12 is adjacent to the hole 14. One side of the shaft 200 is fixed to one side of the first connecting portion 12. The shaft 200 passes through and pivotally connects to one bottom of the support frame 210. One side of the first positioning member 220 is fixed to one side of the support frame 210. The shaft 200 passes through and pivotally connects to one bottom of the first positioning member 220. The support frame 210 connects to and supports the second housing 30.

[0074] Continuing from the above, in this embodiment, one side of the first gear 230 is adjacent to the other side of the first positioning member 220 and fixed to the other side of the shaft member 200. The first gear 230 includes a first gear body 231 and a tooth 233. The tooth 233 is disposed on the outside of the first gear body 231, and the first gear body 231 is fixed to the shaft member 200.

[0075] Continuing from the above, in this embodiment, the second positioning member 240 is disposed adjacent to the other side of the first gear 230, and the shaft member 200 passes through and pivotally connects to a bottom of the second positioning member 240. The second positioning member 240 includes a positioning body 241, a second positioning member groove 243, a first pivot rod 245, and a second pivot rod 247. The second positioning member groove 243 passes through one side of the positioning body 241. One side of the first pivot rod 245 and one side of the second pivot rod 247 are fixed to the same side of the positioning body 241. The other side of the first pivot rod 245 and the other side of the second pivot rod 247 are fixed to the other side of the first positioning member 220.

[0076] Continuing from the above, in this embodiment, the second gear 250 is disposed between the first positioning member 220 and the second positioning member 240. The second gear 250 meshes with the tooth portion 233 of the first gear 230. The second gear 250 includes a second gear pivot hole 252. The first pivot rod 245 of the second positioning member 240 is pivotally connected to the second gear pivot hole 252, so that the second gear 250 can rotate on the second positioning member 240.

[0077] Continuing from the above, in this embodiment, the third gear 260 is disposed between the first positioning member 220 and the second positioning member 240. The third gear 260 meshes with the second gear 250. The third gear 260 includes a third gear pivot hole 262, and the second pivot rod 247 is pivotally connected to the third gear pivot hole 262, allowing the third gear 260 to rotate on the second positioning member 240. An extension rod is provided on one side of the third gear 260. The extension member 264 has a third gear slide rod 2642 on one side, which is slidably disposed in the second positioning member slide groove 243 of the second positioning member 240. A third pivot rod 2644 is provided on the side of the extension member 264 adjacent to the third gear slide rod 2642. The pivot hole 421 of the cover plate 40 is pivotally connected to the third pivot rod 2644, so that when the third gear 260 rotates, it drives the cover plate 40 to move accordingly.

[0078] Continuing from the above, such as Figures 2A to 2C as well as Figures 3A to 3D As shown, in this embodiment, when the second housing 30 is unfolded, the second housing 30 rotates relative to the shaft 200 via the support frame 210. The shaft 200 drives the first positioning member 220 and the second positioning member 240 to rotate relative to the shaft 200. Since the first gear 230 is fixed to the shaft 200, the shaft 200 drives the first gear 230 to rotate, which in turn drives the second gear 250 to rotate. The second gear 250 rotates at the first pivot rod 245 and... The third gear 260 is driven to rotate on the second pivot rod 247. When the third gear 260 rotates, it drives the third gear slide rod 2642 to slide in the second positioning member groove 243, causing the extension 264 to push the cover plate extension 42. The cover plate extension 42 drives the cover plate slide rod 423 to slide in the housing groove 52, and causes the cover plate 40 to protrude from the opening 32 and move to one side of the opening 32. At this time, the opening 32 is open and corresponds to the hole 14 of the first housing 10.

[0079] Continuing from the above, conversely, when the second housing 30 is closed, as the second housing 30 rotates relative to the shaft 200 via the support frame 210, the first positioning member 220 and the second positioning member 240 rotate relative to the shaft 200, and the second gear 250 rotates relative to the shaft 200. The second gear 250 rotates on the first pivot rod 245 and drives the third gear 260 to rotate on the second pivot rod 247. The third gear slide rod 2642 slides on the second positioning member slide groove 243, causing the cover plate slide rod 423 to slide on the housing slide groove 52, causing the cover plate 40 to retract into the opening 32.

[0080] Continuing from the above, in one embodiment, the second positioning groove 243 is arc-shaped.

[0081] See again Figures 1A to 2C This embodiment is the third embodiment, which is based on the second embodiment described above. In this embodiment, the first gear 230 further includes a first idle stroke portion 235 and a second idle stroke portion 237. The gear portion 233, the first idle stroke portion 235 and the second idle stroke portion 237 are disposed above the first gear body 231.

[0082] Continuing from the above, in this embodiment, a bottom of the first gear 230 is fixed to the shaft 200. When the first positioning member 220 and the second positioning member 240 rotate on the shaft 200, the first positioning member 220 and the second positioning member 240 drive the second gear 250 to move from the first idle stroke portion 235 of the first gear 230 to engage the tooth portion 233.

[0083] Continuing from the above, before the second gear 250 moves from the toothed portion 233 to the second idle stroke portion 237, the second gear 250 meshes with the third gear 260, causing the third gear 260 to rotate and thus drive the third gear slide rod 2642 of the extension member 264 to slide in the second positioning member groove 243. Due to the stroke design of the second positioning member groove 243, the extension member 264 guides the cover plate extension member 42 upward. At this time, the cover plate slide rod 423 slides in the housing groove 52. Further through the stroke design of the housing groove 52, the cover plate 40 is moved away from the opening 32 and away from the second housing 30.

[0084] Continuing from the above, as the second housing 30 continues to rotate relative to the shaft 200, the second gear 250 begins to move and meshes with the tooth 233 of the first gear 230 to the second idle stroke portion 237. At this point, the second gear 250 stops moving, and the third gear 260 rotates, thereby causing the third gear slide rod 2642 of the extension 264 to slide in the second positioning member groove 243. The stroke design of the second positioning member groove 243 during this stage allows the extension 264 to guide the cover plate extension. 42 moves, at which point the cover slide rod 423 slides in the housing slide groove 52. The travel design of the housing slide groove 52 at this stage allows the cover 40 to continue moving parallel to the second housing 30 at a certain interval. When the third gear slide rod 2642 stops sliding in the second positioning slide groove 243, the second housing 30 has moved away from the first housing 10 and is only connected by the support frame 210. The cover 40 aligns the opening 32 of the second housing 30 with the hole 14 of the first housing 10.

[0085] Continuing from the above, when the second gear 250 enters the second idle stroke section 237, it does not move until the second housing 30 is closed. Then, the second gear 250 re-engages with the tooth 233 of the first gear 230, causing the cover plate 40 to cover the opening 32 of the second housing 30.

[0086] See again Figures 1A to 2C This embodiment is the fourth embodiment, which is based on the second embodiment described above. In this embodiment, a magnetic suction member 44 is provided on the bottom surface of the cover plate 40. When the cover plate 40 is completely retracted into the second housing 30, the cover plate 40 is attracted to the side of the second housing 30 through the magnetic suction member 44 corresponding to the opening 32.

[0087] Continuing from the above, when the third gear slide bar 2642 has slid to stop at the second positioning groove 243, the cover plate 40 protrudes completely from the second housing 30 and moves to one side of the opening 32. The cover plate 40 is then attached to one side of the second housing 30 by the magnetic suction member 44.

[0088] See again Figures 1A to 3D This embodiment is the fifth embodiment, which is based on the first embodiment or the second embodiment described above. In this embodiment, the hole 14 of the first housing 10 is connected to an inner side of the first housing 10 for heat dissipation. For example, the exhaust port of the heat dissipation module of the first housing 10 is connected to the hole 14.

[0089] Continuing from the above, in this embodiment, when the cover plate 40 protrudes from the opening 32 and moves to the side of the second housing 30, a heat flow W from the first housing 10 flows out through the hole 14 to the opening 32, so that the heat flow W from the hole 14 is not blocked by the second housing 30, and can generate convection with the outside through the opening 32.

[0090] Continuing from the above, in one embodiment, the heat flow W is generated by electronic components such as a central processing unit, graphics processor, memory, and solid-state drive inside the first housing 10.

[0091] See again Figures 1A to 3C And see Figures 4A to 4B , Figures 4A to 4B This is a schematic diagram of the usage state of another embodiment of the present invention. This embodiment is the sixth embodiment, which is based on the first embodiment or the second embodiment described above. In this embodiment, the hole 14 of the first housing 10 is further provided with a connection port P1.

[0092] Continuing from the above, in this embodiment, when the cover plate 40 protrudes from the opening 32 and moves to the side of the second housing 30, the opening 32 of the second housing 30 corresponds to the hole 14 of the first housing 10 and the connection port P1, so that a connecting line L1 can pass through the opening 32 and electrically connect to the connection port P1.

[0093] Continuing from the above, in one embodiment, the connection port P1 may be an image connection port (such as DP, HDMI), a USB connection port, an audio source connection port (such as a Combo jack), or a network connection port, and the corresponding connection cable L1 may be an image connection port (such as DP, HDMI), a USB connection port, an audio source connection port (such as a Combo jack), or a network connection port, but this is not a limitation.

[0094] In summary, the present invention provides a recessed laptop in which, when the second casing is rotated open relative to the hinge, the cover plate protrudes outward from the second casing via a connecting assembly. This further aligns the heat dissipation holes of the first casing with the opening of the second casing, dissipating heat flow. This addresses the problem in known recessed laptops where the screen blocks the heat dissipation holes at the rear of the host when the laptop is opened, causing heat flow to concentrate between the screen and the host, thus damaging electronic components inside the host. It also addresses the problem in known recessed laptops where the screen blocks the connection ports at the rear of the host when the laptop is opened.
