[0002] Portable notebooks refer to personal notebook products with high mobility. Generally speaking, notebooks with a screen size of 12 inches or less and a weight of no more than 2kg can be considered portable notebooks. The first consideration for portable notebooks is the portability of the notebook.

[0003] A dual-screen display is a desktop display. Conventionally, the screen is fixed to a bracket with screws to achieve dual-screen interoperability.

The invention patent records that it includes a fixing frame, a first connecting member, a second connecting member, a display module and two wing panels. The two wing panels are respectively rotatably connected to the two ends of the back of the fixing frame. The first connecting member is arranged on the wing panel, and the second connecting member is arranged on the back of the display module. The first connecting member and the second connecting member are magnetically connected. The LCD screen assemblies on both sides are magnetically connected to the main structure to achieve communication and fixation. The LCD screen assemblies on both sides can be placed vertically or horizontally to meet the environmental requirements of using the notebook display for horizontal and vertical display. The two sides of the fixing frame can be pulled left and right to adjust the horizontal size to meet the needs of users who use dual-screen devices. They can be hung on laptop screens of different sizes.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Example

[0022] like Figure 1-5 As shown, the portable notebook double-sided expansion screen includes a support frame 1, a connecting component, a mounting frame 2 and an expansion screen 3; The rear end surface of the support frame 1 is provided with an interface component connected to the laptop computer, and the rear end of the support frame 1 is provided with a limit component 7 near both sides; the number of connecting components is two groups, and the connecting components are detachably installed on both sides of the support frame 1 near the rear end; The mounting frame 2 is mounted on the connection assembly; the extended screen 3 is embeddedly mounted on the mounting frame 2; Among them, the connecting component includes a connecting block 4, a supporting rotating shaft 5 and a 360-degree rotating shaft 6: one end of the supporting rotating shaft 5 is rotatably connected to the connecting block 4, and the other end of the supporting rotating shaft 5 is inserted into the interior of the supporting frame 1 and limited by the limiting component 7; the 360-degree rotating shaft 6 is rotatably installed on the connecting block 4, and the upper end of the 360-degree rotating shaft 6 extends to the interior of the mounting frame 2 and is fixedly connected to the mounting frame 2.

[0023] The 360-degree rotating shaft 6 enables the mounting frame 2 to rotate 360 ​​degrees perpendicular to the desktop, and can be adjusted to other directions when in use, making it convenient for people around to watch, and having a good use effect.

[0024] The interface component includes a type-c interface and a USB interface connected to the two sets of extended screens 3. The display of the two sets of extended screens 3 can be realized by connecting them to a computer, and the two extended screens 3 can be lit, connected and controlled at the same time.

[0025] The rear end face of the mounting frame 2 is also provided with several groups of function keys, which can realize "one-key switching to screen projection", "one-key mute", "one-key screenshot" and "one-key screen off" of the extended screen 3, helping users to use the extended screen 3 more conveniently and protect their privacy. The overall functionality is relatively strong.

[0026] When in use, the connecting block 4 is rotated around the supporting rotating shaft 5, and then the mounting frame 2 is rotated around the 360-degree rotating shaft 6, thereby changing the inclination angle of the mounting frame 2, thereby adjusting the angle of the extended screen 3, so that relevant staff can check it conveniently.

[0027] When stored, the structure is similar to that of a laptop computer, and the extended screen 3 is located inside, which can protect the screen so that it will not be easily damaged and has a longer service life.

[0028] The present invention records a double-sided expansion screen for a portable notebook computer, which changes the existing hanging structure and adopts a support and double rotation structure, so that the double-sided expansion screen of the notebook computer can be folded together when not in use, so that the volume of the double-sided expansion screen of the notebook computer is only slightly larger than the area of ​​a single expansion screen 3, and it is very convenient to carry. Moreover, when in use, it will not generate pressure on the screen shaft of the notebook computer, will not affect the operation of the notebook computer, has good use effect, and has a good use prospect. Example

[0029] like Figure 1-9 As shown, based on Example 1, this embodiment further includes the following structure: The outer surface of the supporting rotating shaft 5 is provided with a plurality of groups of slots 51 at equal intervals, and the limiting assembly 7 is engaged with any group of the slots 51 .

[0030] When in use, when the limiting assembly 7 is engaged with the card slots 51 at different positions, the distance between the two groups of extended screens 3 is different, so that it can be suitable for use with notebook computers of different sizes.

[0031] The limiting assembly 7 includes a movable member 71, a clamping block 72 and a fixing member 73: The movable member 71 is arranged inside the support frame 1 , and a clamping block 72 plugged into the clamping slot 51 is installed on the movable member 71 ; the fixing member 73 is arranged inside the support frame 1 to limit the position of the movable member 71 .

[0032] When the distance between the extended screens 3 is not adjusted, the card block 72 is always inserted into the card slot 51 to limit the position of the supporting rotating shaft 5 and prevent the supporting rotating shaft 5 from rotating.

[0033] A pressing block 74 is mounted on the movable member 71 , and a clamping member 75 for locking the pressing block 74 is mounted on the fixed member 73 .

[0034] The pressing block 74 and the clamping member 75 are conventional locking structures, and therefore their specific shapes will not be described in detail.

[0035] When adjusting the distance between the extended screens 3, the push-type clamping block 74 and the clamping member 75 are locked and limited. At this time, the supporting rotating shaft 5 can be directly pulled to change the position of the supporting rotating shaft 5, thereby fixing the position of the extended screen 3.

[0036] The movable part 71 is provided with buttons and a reset component: One end of the button passes through the hole on the support frame 1 and extends to the outside of the support frame 1 ; one end of the reset component is installed on the movable member 71 , and the other end of the reset component is installed inside the support frame 1 .

[0037] When adjusting the distance between the extended screens 3, the button is pressed, and the button drives the movable part 71 to move, thereby driving the push-type card block 74 on the movable part 71 to be plugged into the card block 72. When the position of the supporting rotating shaft 5 is adjusted, the button is pressed again, the push-type card block 74 is separated from the card block 72, and the reset spring 76 restores its deformation, pushing the movable part 71 to move, so that the card block 72 is plugged into the card slot 51, thereby realizing the limiting of the supporting rotating shaft 5.

[0038] The reset component adopts a reset spring 76 , and the number of the reset spring 76 is two groups. The two ends of the reset spring 76 are fixedly connected to the movable part 71 and the inner wall of the support frame 1 respectively.

[0039] The reset component may also be implemented by other elastic structures, such as a spring sheet, or an elastic rope may be used at the other end of the movable member 71 .

[0040] A connecting shaft 41 is installed on the connecting block 4, and the lower end of the 360-degree rotating shaft 6 is rotatably connected to the connecting shaft 41. The 360-degree rotating shaft 6 is inserted into the lower end surface of the mounting frame 2 near the end position, and the 360-degree rotating shaft 6 and the mounting frame 2 are connected by bolts.

[0041] The 360-degree rotating shaft 6 and the supporting rotating shaft 5 both limit the rotation angle by damping.

[0042] Support feet 8 for adjusting the tilt angle of the support frame 1 are installed near both sides of the lower end surface of the support frame 1. The tilt angle of the support frame 1 can be adjusted to facilitate people to better use the laptop computer.

[0043] Figure 1 In order to show the structure of the supporting foot 8, the entire structure is flipped over and displayed, with the actual supporting foot 8 located at the bottom.

[0044] The present invention records a double-sided expansion screen for a portable notebook computer, in which a connecting component is provided, wherein a supporting rotating shaft 5 cooperates with a limiting component 7 to change the distance between two groups of expansion screens 3, so that the expansion screen 3 can be suitable for notebook computers of different widths, and the overall applicability is relatively high. The connecting block 4 can rotate relative to the supporting rotating shaft 5, and the mounting frame 2 can rotate around a 360-degree rotating shaft 6, so that the expansion screen 3 can present a wide range of angles, which is suitable for the needs of different groups of people, has a good use effect, and has a good prospect of use. Example

[0045] In the prior art, the connection of portable expansion screens usually relies on standard transmission protocols such as USB, HDMI, and Thunderbolt. However, with the increase in demand for high-resolution displays, the transmission bandwidth has become a bottleneck that limits the efficiency of data transmission, especially in high-performance display and high frame rate scenarios. In addition, the heat generated during high-speed transmission often causes the device temperature to be too high, affecting the stability and service life of the system. Existing solutions mainly solve these problems by increasing the transmission bandwidth or adding heat dissipation components, but the two are often not taken into account at the same time, and there is still a contradiction between transmission efficiency and heat dissipation effect.

[0046] In order to solve the above problems, the present invention provides a new data transmission control method when a portable expansion screen is connected. The method can intelligently adjust the data transmission rate and heat dissipation mechanism, thereby effectively reducing heat accumulation while ensuring efficient transmission and ensuring stable operation of the equipment.

[0047] The core idea of ​​the present invention is: by combining dynamic data transmission adjustment and intelligent thermal management system, the high load and high heat generation during data transmission can be intelligently adjusted according to the actual use environment and equipment status to achieve a balance between transmission efficiency and heat dissipation problems.

[0048] A new data transmission control method when a portable expansion screen is connected, comprising: Step 1: Estimation of data transfer rate and cooling requirements 1. After the portable expansion screen is connected to the main device, the system first detects the current transmission rate and display requirements (such as resolution, refresh rate, color depth, etc.) through the data transmission protocol.

[0049] 2. Based on the current transmission load and display requirements, the system estimates the heat that may be generated during the current data transmission process and establishes a dynamic heat load model.

[0050] Step 2: Dynamically adjust the data transmission rate 1. When it is confirmed that the transmission load is too high (such as high resolution, high frame rate display requirements), the system automatically reduces the data transmission rate or resolution based on real-time temperature data and thermal load model to reduce the heat generated.

[0051] 2. When the temperature is low or the system load is light, the system can appropriately increase the data transmission rate or optimize the display parameters to improve transmission efficiency and display quality.

[0052] Step 3: Intelligent thermal management control 1. Based on real-time temperature sensor data, the system determines the temperature of key components of the device (such as processor, display panel, transmission interface, etc.).

[0053] 2. When the device temperature reaches a preset threshold, the system automatically enables a cooling mechanism (such as a fan, heat pipe, or liquid cooling system) and dynamically adjusts the cooling effect based on temperature changes. For example, the system can automatically adjust the fan speed or start additional cooling components based on temperature changes.

[0054] 3. When the device is in a low temperature state or the transmission load is light, the system can automatically shut down or reduce the working intensity of the cooling system to avoid unnecessary noise and power consumption.

[0055] Step 4: Coordinated optimization of transmission protocol and heat dissipation 1. The system dynamically optimizes the way data packets are sent based on the bandwidth limit and heat load of the transmission protocol (such as USB4, Thunderbolt, etc.). For example, under high load, the system may reduce bandwidth usage and heat accumulation by optimizing data compression or delaying the transmission of certain non-critical data.

[0056] 2. During high-bandwidth transmission, the system will prioritize enabling additional hardware acceleration functions (such as GPU or dedicated acceleration chips) to ensure stability and efficiency during data transmission and reduce CPU load, thereby reducing heat generation.

[0057] Step 5: Long-term temperature control strategy 1. The system will learn the temperature control performance of the device under different working modes during long-term use, and gradually optimize the adjustment strategy of data transmission rate and heat dissipation mechanism, so that the device can be intelligently adjusted according to the actual usage scenario.

[0058] 2. The system also supports user-defined temperature control strategies to adapt to different usage environments (such as office environments, outdoor high temperature environments, etc.).

[0059] The present invention combines dynamic data transmission rate with heat dissipation strategy. Different from the prior art that treats data transmission rate and heat dissipation system as independent modules, the present invention proposes an innovative method of dynamic coordination between the two, which can be intelligently adjusted according to equipment load and environmental conditions in real time, thereby improving transmission efficiency and heat dissipation effect. The present invention adopts an intelligent heat load prediction and transmission adjustment mechanism. By establishing a dynamic heat load model and combining data transmission with real-time monitoring of equipment temperature, it accurately predicts heat generation under high load, thereby providing data support for the optimization of data transmission rate and heat dissipation strategy. The present invention provides a temperature control optimization mechanism based on long-term learning through user-defined temperature control and intelligent adjustment, and users can adjust the transmission rate and heat dissipation strategy according to specific needs, providing higher flexibility and adaptability. It has the following beneficial effects: 1. Efficient data transmission: By dynamically adjusting the transmission rate and optimizing data flow control, the present invention ensures that data transmission remains efficient and stable under high load conditions.

[0060] 2. Reduce device temperature: The system monitors in real time and intelligently adjusts the heat dissipation method to avoid excessive heating, extend the life of the device, and ensure that the temperature is always maintained within a reasonable range during use.

[0061] 3. Improve user experience: The adaptive adjustment mechanism of the present invention reduces the need for user intervention in different environments, can automatically optimize the working state, and improve the user experience of the portable expansion screen.

[0062] In summary, the present invention provides a new data transmission control method when a portable expansion screen is connected. By intelligently adjusting the data transmission rate and the heat dissipation strategy, it effectively solves the problems of efficient transmission and heat dissipation, improves the performance and stability of the equipment, and reduces the risk of overheating, providing a new solution for portable expansion screen technology.
