Abstract
Description
Technical Field
[0001] This invention relates to the field of heat dissipation technology for electronic products, and in particular to a rear-moving hinge structure, a heat dissipation control system, and an electronic product. Background Technology
[0002] The design trend of laptops has always been towards thinner and smaller designs. In order to provide a better user experience, the heat vents are usually moved to the rear, and a recessed hinge design is often chosen to achieve a higher screen-to-body ratio.
[0003] However, the disadvantage of the recessed hinge is that when the display is opened, the bottom of the display will block the rear heat vent, causing hot air to flow back. This not only affects the heat dissipation efficiency of the whole machine, but also leads to problems such as excessively high surface temperature of the casing, reduced processor performance, and system overheating and crashes.
[0004] To address the aforementioned issues, an additional air vent is added to improve heat dissipation efficiency. Specifically, the system's base plate is separated from the casing to form a new air vent, created by the rotation of a pivot. However, this method still doesn't solve the problem of the original air vent being blocked, and the new vent relies entirely on the pivot's support. The pivot's limited support force prevents users from pressing too hard on the casing while operating the system. Summary of the Invention

[0034] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0035] This invention provides a heat dissipation control system, including a controller, a rear-moving hinge structure, and a notification device. The controller acquires relevant information and determines whether the rear-moving hinge structure needs to be activated. When the acquired information reaches a set range, it indicates that auxiliary heat dissipation is required, and the rear-moving hinge structure moves backward to increase the heat dissipation space of the air outlet, thereby improving the heat dissipation efficiency of the air outlet. Conversely, when the acquired information is outside the set range, the rear-moving hinge structure resets.
[0036] The following description, in conjunction with the accompanying drawings, details the various structures of the heat dissipation control system provided by the present invention, the connection relationships between the structures, and their positional relationships.
[0037] like Figures 1 to 9 As shown, in this embodiment of the invention, the controller includes an acquisition module; the acquisition module is configured to acquire the rotational speed information of the cooling fan or the temperature information at a set position; the controller controls the start and stop of the linear drive module 32 according to the rotational speed information or the temperature information.
[0038] For example, when the cooling fan is running under high load, its speed is high. The speed of the fan can be obtained through the speed sensor. After the speed reaches the set range, the linear drive module 32 is activated to move, that is, the shaft moves backward (the specific backward movement method is described in the following text). Conversely, the linear drive module 32 is not activated to move, or the activated linear drive module 32 is reset in the reverse direction.
[0039] Alternatively, for example, temperature information at a set location can be obtained through a temperature sensor. For instance, if the temperature sensor is set at the location of the air outlet, and the temperature of that part is too high, it indicates that further heat dissipation is needed, and the linear drive module 32 can be activated to move backward.
[0040] In the technical solution of this invention, the fan speed information or the temperature information at the set position are two relatively intuitive and accurate parameters. However, the information obtained can also be of other types. For example, the processor temperature information or the software running information can be obtained. For instance, when the set software is running, the linear drive module 32 is activated to move backward.
[0041] Alternatively, for example, the start and stop of the linear drive module 32 moving backward is performed periodically. After the electronic product has been running for a period of time, the linear drive module 32 is started to move backward, and then the linear drive module 32 is reset. After a period of time after the reset, it starts to move backward again. This operation is repeated throughout the operation of the electronic product.
[0042] In this embodiment of the invention, the controller further includes a prompt information sending module, which is configured to issue a prompt signal when the speed or temperature information of the cooling fan is within a set range.
[0043] For example, the prompt message sending module is used to send a prompt signal to the display device, and the display device will display a pop-up prompt; or the prompt message sending module is used to send a prompt signal to the sound and light reminder device, and the sound and light reminder device will provide sound and / or light and light prompts.
[0044] The hinge movement occurs during the operation of electronic products; therefore, prompts can be provided to the user during movement and reset. For example, a pop-up notification can be used, conveniently located in the center or corner of the screen. Audible and visual prompts can also be used. Taking a laptop as an example, an indicator light can be placed at the edge of the touchpad. Normally, the light is off or constantly illuminated in one color. When the hinge moves backward or resets, a different color is displayed to serve as a reminder. For example, it might be green normally, and red when the hinge moves backward or resets.
[0045] In this embodiment of the invention, the prompts regarding the movement of the rotating shaft can also be customized. For example, prompts can be customized according to the user's individual needs. For instance, based on pop-up prompts, the prompt content can be customized; based on audio-visual prompts, the sound content or light / electric color can be customized. Alternatively, other reminder methods can be customized, such as vibration reminders or breathing light reminders.
[0046] Continue to refer to Figures 1 to 9 As shown, in this embodiment of the invention, the rear movable pivot structure includes a housing assembly 10, a pivot assembly 20, and a drive assembly 30; the housing assembly 10 includes a housing body 11, a fixed bracket 12, and a movable bracket 13. The housing body 11 includes a notch 111. The fixed bracket 12 and the movable bracket 13 are stacked at the notch 111, and the fixed bracket 12 is fixedly connected to the housing body 11.
[0047] In this embodiment of the invention, the pivot is designed to be movable, so that part of the housing assembly 10 is designed as a split structure, that is, the housing assembly 10 is not a complete whole. In order to reduce the difference in appearance, the outer shape area of the housing assembly 10 can be a whole structure when the pivot structure is not moved backward.
[0048] For example, the main body 11 includes a first housing 112 and a second housing 113, with notches 111 respectively provided on the first housing 112 and the second housing 113, and the fixed bracket 12 is connected to the inner wall of the first housing 112 or the second housing 113; the movable bracket 13 includes a first sub-housing 131 and a second sub-housing 132, with the first sub-housing 131 located at the notch 111 of the first housing 112 and the second sub-housing 132 located at the notch 111 of the second housing 113, and the first connecting plate 21 and the linear drive module 32 are connected to the first sub-housing 131 or the second sub-housing 132.
[0049] The first sub-shell 131 and the second sub-shell 132 are located on both sides of the fixed bracket 12, and the outline shape of the first sub-shell 131 and the second sub-shell 132 is the same as the cross-sectional shape of the notch 111. In the normal state (without being moved back), the first sub-shell 131 and the second sub-shell 132 are located inside the notch 111, and their edge outlines form a complete structure with the outlines of the first shell 112 and the second shell 113.
[0050] The first connecting plate 21 is connected to the edge of the first sub-shell 131, maximizing the movement distance of the pivot assembly 20 when it is moved backward. For example, the movement range of the rear-moving pivot structure is 5 mm to 15 mm. For example, the movement distance of the rear-moving pivot structure is 10 mm, but when there is a need for heat dissipation, the air outlet is increased by 10 mm to provide more sufficient heat dissipation, reduce backflow, and improve heat dissipation efficiency.
[0051] For example, sliding components 40 are respectively provided between the first sub-shell 131 and the first shell 112, and between the first sub-shell 131 and the fixed bracket 12, and / or, sliding components 40 are respectively provided between the second sub-shell 132 and the second shell 113, and between the second sub-shell 132 and the fixed bracket 12; the sliding direction of the sliding components 40 is the same as the moving direction of the linear drive module 32. For example, the sliding component 40 includes a sliding protrusion 41 and a strip slide rail 42; the sliding protrusion 41 is provided on the first sub-shell 131 and / or the second sub-shell 132, and the strip slide rail 42 is provided on the first shell 112 and / or the second shell 113; or, the sliding protrusion 41 is provided on the first shell 112 and / or the second shell 113, and the strip slide rail 42 is provided on the first sub-shell 131 and / or the second sub-shell 132.
[0052] As shown in the figure, it includes two sets of sliding components 40. One set is located on both sides of the first sub-shell 131, with sliding protrusions 41 respectively provided on both sides of the first sub-shell 131. Strip rails 42 are respectively provided on the fixed bracket 12 on the same side. The sliding distance of the sliding protrusions 41 within the strip rails 42 is the moving distance of the rear-moving rotating shaft structure. The other set is located on the end face of the first sub-shell 131 where the rotating shaft assembly 20 is installed. Two parallel sliding protrusions 41 are provided on this end face. Strip rails 42 are provided on the fixed bracket 12. The strip rails 42 cooperate with the sliding protrusions 41 for guidance.
[0053] In this embodiment of the invention, the hinge assembly 20 includes a first connecting plate 21 and a second connecting plate 22. The first connecting plate 21 is connected to the first sub-shell 131 or the second sub-shell 132, and the second connecting plate 22 is used to connect to the shell of other structures. Taking a laptop as an example, the hinge assembly 20 is set on the shell of the system end, and the second connecting plate 22 is used to connect to the shell of the display end.
[0054] For example, a sliding assembly 40 is provided between the fixed bracket 12 and the first connecting plate 21, as shown in the figure. A sliding protrusion 41 is provided on the first connecting plate 21, and a strip groove that cooperates with the sliding protrusion 41 is provided on the fixed bracket 12. When the rotating shaft assembly 20 moves, the sliding protrusion 41 and the strip groove cooperate to guide it.
[0055] Continue to refer to Figures 1 to 9 As shown, in this embodiment of the invention, the driving component 30 includes a slider 31 and a linear driving module 32. The linear driving module 32 is slidably connected to the slider 31, the slider 31 is connected to the fixed bracket 12, and the linear driving module 32 is connected to the movable bracket 13. The linear driving module 32 is used to drive the movable bracket 13 and the rotating shaft assembly 20 to move to the outside of the notch 111.
[0056] By controlling the forward or reverse rotation of the linear drive module 32, the rearward movement or reset of the rear-moving rotating shaft structure can be adjusted. For example, the linear drive module 32 includes a frame 321, a drive motor 322, a gearbox 323, and a linear screw 324; the drive motor 322, gearbox 323, and linear screw 324 are mounted on the frame 321, which is connected to either the first sub-shell 131 or the second sub-shell 132; the output shaft of the drive motor 322 is connected to the driving gear of the gearbox 323, the linear screw 324 is connected to the driven gear of the gearbox 323, and the linear screw 324 is screwed to the slider 31.
[0057] By controlling the forward or reverse rotation of the drive motor 322, the forward or reverse rotation of the linear screw 324 can be controlled, thereby achieving position adjustment of the rear-moving shaft structure. For example, the gearbox 323 can adjust the number of gears according to the speed distribution, that is, multiple intermediate gears can mesh between the driving gear and the driven gear.
[0058] For example, the linear drive module 32 can also adopt other telescopic movement drive methods, such as cylinder drive.
[0059] For example, the linear screw 324 is set in the direction of movement of the rotating shaft assembly 20, or the linear screw 324 is set in a direction perpendicular to the direction of movement of the rotating shaft assembly 20. In this structure, the slider 31 can swing along a set angle. As the linear screw 324 and the slider 31 rotate relative to each other, the sliding swing drives the fixed bracket 12 to move along the direction of movement of the rotating shaft assembly 20.
[0060] This invention provides an electronic product, including the aforementioned rear-moving hinge structure or the aforementioned heat dissipation control system. Taking a laptop computer as an example, the laptop computer includes a system end and a display end, wherein the rear-moving hinge structure is disposed on the system end, and the second connecting plate 22 of the hinge assembly 20 is connected to the display end.
[0061] When a laptop starts up and runs for a period of time or runs large software, it operates under high load, causing its internal temperature to rise. When the detected temperature or fan speed exceeds the set conditions, a message pops up in the lower right corner of the display screen to notify the user that the hinge is about to move backward. At the same time, the indicator light on the touchpad will change from green to red to warn that the system temperature is too high and the hinge opens to move backward. When the drive motor 322 (such as a servo motor) receives a signal from the system, it drives the linear screw 324 to rotate, causing the hinge to move backward, so that the air vent at the system end has more space for heat dissipation.
[0062] The laptop continues to run after the hinge moves backward. When the system temperature or fan speed falls below the set conditions, a message pops up in the lower right corner of the display screen to notify the user that the hinge is about to start resetting. At the same time, the indicator light on the touchpad changes from red to green, and the servo motor moves in the opposite direction, causing the hinge to reset.
[0063] The present invention provides a technical solution in which the rotating shaft structure is moved backward, which can alleviate or avoid obstruction of the air outlet, thereby improving heat dissipation efficiency. Furthermore, the way the rotating shaft structure is moved backward does not change the other structures of the housing assembly 10, and can provide stable support.
