[0051] Example 1

[0052] The integrated touch screen assembly provided in this embodiment is applied to a notebook computer. By optimizing the structure, it can add the power on / off function of the notebook computer without affecting its own functions, and has the advantage of low cost.

[0053] like Figures 1 to 6 As shown, the integrated touch screen assembly of this embodiment includes:

[0054] PCB board 10 is used to be electrically connected to the computer motherboard; wherein, PCB board 10 can transmit touch signals and click signals to the computer motherboard to simulate the mouse function, and can also transmit power on / off signals to the computer motherboard to control the power on and off of the laptop;

[0055] The touch screen unit 20 is stacked on the PCB board 10. The specific form of the touch screen unit 20 is not particularly limited, and it can be an integrated touch screen or a split touch screen.

[0056] The power button unit 31 is electrically connected to the PCB board 10. The power button unit 31 uses a dome (also known as a pot piece). When pressed, the PCB board 10 can promptly receive a feedback signal of the power button being pressed through the dome.

[0057] The touch and click button unit 32 is electrically connected to the PCB board 10. The touch and click button unit 32 uses a dome (also known as a dome). When pressed, the PCB board 10 can promptly receive a feedback signal indicating that the touch screen has been clicked through the dome.

[0058] The power trigger unit is provided on the touch screen unit 20 and is used to press the power button unit 31 under the action of an external force; that is, the user can apply pressure to the power trigger unit to send a power on / off signal to the computer motherboard;

[0059] The outer bracket unit 40 is arranged on a side of the PCB board 10 away from the touch screen unit 20 and is movably connected to the PCB board 10; wherein, the outer bracket unit 40 can be formed by bending a sheet metal part and installed on the C-shell of the laptop computer to carry the PCB board 10 and the touch screen unit 20, wherein the movable connection with the PCB board 10 provides a movable space for clicking the touch screen.

[0060] In this embodiment, the PCB 10 is connected to the computer motherboard via a 12-pin connector, with 8 pins used for touchscreen signal transmission and 4 pins for power on and off, resulting in a high degree of integration. It should be noted that in this embodiment, the power button unit 31 is located at one end of the PCB 10, and the touch-click button unit 32 is located at the other end of the PCB 10. This allows the user to easily distinguish between the power on and off functions and to avoid accidental touches. In other optional embodiments, the power button unit 31 and the touch-click button unit 32 can be located at the same end of the PCB 10.

[0061] Specifically, the integrated touch screen assembly of this embodiment integrates the power button unit 31 and the touch click button unit 32 into the PCB board 10, so that the integrated touch screen assembly has both the original click function and the power on / off function. Since the power button unit 31 is electrically connected to the PCB board 10, and the PCB board 10 is electrically connected to the computer motherboard, the power-on signal can be transmitted through the PCB board 10. Therefore, when assembling the laptop computer, no additional manpower is required to electrically connect the power button unit 31 to the computer motherboard, nor is there any need to perform operations such as cracking the C-shell and locking the power button unit 31, thereby reducing labor costs. At the same time, the power connection cable is eliminated, reducing material costs. In summary, this integrated touch screen assembly and laptop computer are lower in cost than conventional solutions. At the same time, it should be understood that this solution utilizes the original PCB board 10 of the touch screen assembly and the connection between the PCB board 10 and the computer motherboard, which saves materials. At the same time, it also utilizes the original process of attaching the touch click button unit 32 to the PCB board 10. For the staff, the labor cost of performing two attachment processes is far less than the labor cost of cracking the shell and locking processes.

[0062] Furthermore, if Figures 1 to 4As shown, the power button unit 31 and the touch-click button unit 32 are both connected to the wall surface of the PCB board 10 away from the touch screen unit 20. The power trigger unit includes a button symbol portion 23 and a power abutment portion 41. The button symbol portion 23 is formed on the touch screen unit 20 by silk screen printing, and the power abutment portion 41 is protruded on the outer bracket unit 40 at the position corresponding to the power button unit 31. When the user needs to turn the device on or off, by pressing the button symbol portion 23, the power button unit 31 moves in a direction closer to the outer bracket unit 40. The power abutment portion 41 then abuts against the power button unit 31, causing the power button unit 31 to deform and transmit the press signal to the PCB board 10. In this structure, the glass layer 21 of the touch screen unit 20 is utilized, and the outer bracket unit 40 (made of sheet metal, which easily forms the raised power abutment portion 41 and is low-cost) is also utilized to achieve the advantages of simple assembly, low cost, and compact structure of the power button unit 31.

[0063] It should be added that the outer bracket unit 40 is also provided with a click abutment 42 at the position corresponding to the touch click button unit 32. When the touch click button unit 32 moves downward under the action of external force, the click abutment 42 will cause the touch click button unit 32 to deform, thereby transmitting the click signal.

[0064] Furthermore, if Figure 3 and Figure 4 As shown, a first inner bracket unit 71 is further provided between the PCB board 10 and the outer bracket unit 40. The first inner bracket unit 71 is fixedly connected to the PCB board 10. A plurality of flexible support blocks 73 are provided between the first inner bracket unit 71 and the outer bracket unit 40. The plurality of flexible support blocks 73 are arranged around the power button unit 31. An elastic region is formed between the plurality of flexible support blocks 73, and the size of the elastic region matches the size of the key symbol portion 23. Specifically, by forming the elastic region between the first inner bracket unit 71 and the outer bracket unit 40, when a user presses the key symbol portion 23, the elastic region provides good tactile feedback, thereby optimizing the user's user experience. It should be understood that the area of ​​the touch screen unit 20 corresponding to the first inner bracket unit 71 is the upper region. The upper region includes the elastic region described above. Within the upper region, the area outside the elastic region is referred to as the rigid region. Through the above arrangement, the user can effectively prevent the power button unit 31 from being accidentally triggered, thereby further optimizing the user's user experience.

[0065] In a specific embodiment, there are two flexible support blocks 73, and the two flexible support blocks 73 are symmetrically arranged about the power button unit 31; the size of the flexible support block 73 is 7mm*3.5mm*1.5mm, and the center gap between the flexible support block 73 and the power button unit 31 is 15mm. Therefore, the size of the entire elastic area is 30*8mm (greater than 7mm because there are no other parts on the edge of the flexible support block 73, which will be appropriately wider than the flexible support block 73). At the same time, the first inner bracket unit 71 is provided with a plurality of support point portions 74 protruding from the outside of the elastic area, and the support point portions 74 abut against the outer bracket unit 40. In this embodiment, the number of support point portions 74 is 8, divided into two groups of four, and the two groups of support point portions 74 are also symmetrically arranged about the power button unit 31.

[0066] On the basis of the above embodiment, the flexible support block 73 is a foam block. It should be understood that the flexible support block 73 can also be made of elastic materials such as rubber blocks.

[0067] Furthermore, if Figure 5 and Figure 6 As shown, a second inner bracket unit 72 is also provided between the PCB board 10 and the outer bracket unit 40. It should be added that the above-mentioned first inner bracket unit 71 and the second inner bracket unit 72 are both bonded to the PCB board 10 by adhesive, which has the advantage of compact structure; the second inner bracket unit 72 is fixedly connected to the PCB board 10.

[0068] At the same time, a balance bar assembly is mounted on the second inner bracket unit 72 to enhance the touch and click feel, and the end of the balance bar assembly away from the second inner bracket unit 72 abuts against the outer bracket unit 40. In one specific embodiment, the second inner bracket unit 72 is rotatably connected to a balance bar unit 81. Both ends of the balance bar unit 81 are provided with protruding sleeve portions 82, each of which is provided with a balancing movable groove 83. A balance column unit 84 is threadedly connected to the outer bracket unit 40, and the balance column unit 84 passes through the balancing movable groove 83 and can move within the balancing movable groove 83. A spring unit 85 is sleeved on the balance column unit 84, and one end of the spring unit 85 abuts against the second inner bracket unit 72, and the other end abuts against the outer bracket unit 40. Specifically, when the user presses the bottom area (click area) of the touch screen unit 20, the second inner bracket unit 72 drives the balance rod unit 81 to press down, and the sleeve portion 82 at its end will rise under the action of the balance movable groove 83 and the balance column unit 84, thereby balancing the pressure and optimizing the user's tapping experience. Among them, the setting of the spring unit 85 causes the sleeve portions 82 at both ends to be stretched, making the structure of the balance rod unit 81 more stable.

[0069] In another specific embodiment, Figure 9As shown, the second inner support unit 72 is rotatably connected to the balance bar unit 81. A guide portion 88 is mounted on the outer support unit 40, and a guide groove 89 is defined in the guide portion 88. A first connecting portion 86 extends from each end of the balance bar unit 81. The first connecting portion 86 is connected to a second connecting portion 87, and the second connecting portion 87 can slide in the guide groove 89. A spring unit 85 is disposed in the guide groove 89, and is disposed between the top wall of the guide groove 89 and the second connecting portion 87. Specifically, when a user presses the bottom area (click area) of the touch screen unit 20, the second inner support unit 72 drives the balance bar unit 81 downward, causing the first connecting portion 86 to press downward. Subsequently, under the action of the guide groove 89, the second connecting portion 87 slides upward. During this process, the distance between the first connecting portion 86 and the second connecting portion 87 increases, and the spring unit 85 is in a compressed state. The second connecting portion 87 and the first connecting portion 86 provide a reaction force to the balance bar unit 81, providing a good tapping feeling for the user.

[0070] In summary, the integrated touch screen assembly of this embodiment has both mouse simulation function and power on / off function, and has the advantages of low cost, structural stability, good user experience, and simple assembly.

[0071] Example 2

[0072] like Figure 8 like Figure 9 As shown, the difference between the integrated touch screen assembly of this embodiment and the embodiment 1 is that the structures of the power button unit 31 and the power trigger unit are different; specifically, the power button unit 31 is connected to the wall surface of the PCB board 10 close to the touch screen unit 20, and the touch click button unit 32 is connected to the wall surface of the PCB board 10 away from the touch screen unit 20; the touch screen unit 20 is provided with a power avoidance groove 24 at the position corresponding to the touch click button unit 32 and the power trigger unit; the power trigger unit includes a trigger bottom cover unit 50 and a trigger top cover unit 60; the trigger The bottom cover unit 50 is fixedly connected to the PCB board 10 and is provided with a first clip 51, which is arranged in the power avoidance groove 24; the trigger top cover unit 60 is arranged in the power avoidance groove 24 and is provided with a second clip 62 corresponding to the position of the first clip 51. The first clip 51 and the bottom of the power avoidance groove 24 form a clip movable groove, and the second clip 62 can move in the clip movable groove; the trigger top cover unit 60 is provided with a power trigger part 61 corresponding to the position of the power button unit 31, and the power trigger part 61 can abut against the power button unit 31.

[0073] For example, when the trigger cover unit 60 is pressed, the power trigger portion 61, constrained by the power avoidance slot 24 and the two clips, squeezes the power button unit 31, triggering the power on / off signal. In the above structure, the trigger cover unit 60 cooperates with the trigger bottom cover unit 50. No matter where the user clicks on the touch screen unit 20, as long as they do not click the trigger cover unit 60, no accidental touches will occur, thus optimizing the user experience.

[0074] In this embodiment, the touch screen unit 20 includes a backlight layer 22 and a glass layer 21 stacked sequentially in a direction away from the PCB board 10. The glass layer 21 defines a first avoidance hole 211, and the backlight layer 22 defines a second avoidance hole 221. The first avoidance hole 211 and the second avoidance hole 221 form a power avoidance slot 24. The second avoidance hole 221 is larger than the first avoidance hole 211, and the first and second latches 51 and 62 both protrude beyond the edges of the first avoidance hole 211. By adjusting the sizes of the first and second avoidance holes 211 and 221, a movable slot is created in the wall of the power avoidance slot 24, within which the first and second latches 51 and 62 are confined. This further improves overall stability while maintaining a low cost and compact structure.

[0075] In summary, the integrated touch screen assembly of this embodiment has both mouse simulation function and power on / off function, and has the advantages of low cost, structural stability, good user experience, and compact structure.

The specific structure and technical effects of the integrated touch screen assembly are described in embodiments 1 and 2. The laptop computer of this embodiment refers to the structure and also has the same technical effects.

[0078] Furthermore, the laptop computer also includes:

[0079] A monitoring module, used to detect the pressing time of the power button unit 31 in the power-on state;

[0080] A detection module, configured to send a shutdown signal when detecting that the pressing time exceeds a preset time threshold;

[0081] The shutdown module is used to execute the shutdown command when receiving the shutdown signal.

[0082] Through the above settings, it is possible to avoid shutdown caused by the user accidentally touching the power trigger unit, thereby optimizing the user experience.

[0083] In summary, the laptop computer of this embodiment integrates the mouse simulation function and the power on / off function on the touch screen, and has the advantages of low cost, structural stability, and good user experience.
