Description

Technical Field

[0001] This utility model relates to the field of capacitive touch screen technology, specifically a panel-bonded capacitive touch screen. Background Technology

[0002] Panel-bonded capacitive touchscreens are a type of touchscreen technology that achieves more stable connections and better performance by directly bonding the capacitive touchscreen to the motherboard or other circuit boards. They work by utilizing the electrical current sensing of the human body.

[0003] When a finger touches the screen, a coupling capacitor is formed, and the finger absorbs a tiny current. The controller determines the touch position by calculating the current ratio, thus achieving precise touch control. However, when existing capacitive touch screens are not in use, the edges of the screen are only protected by the outer frame, while the central area is directly exposed. As a result, when workers place and carry the touch screen, it is easy for the screen to be damaged by collisions with hard objects due to the lack of protection. Utility Model Content

A rotating cylinder 27 is abutted to the surface of the protective plate 2. A slot 28 is opened on the surface of the protective plate 2. The cross-section of the protective plate 2 is U-shaped and fits and moves on the surfaces of the two sets of fixing blocks 21. The size of the protective plate 2 is larger than the size of the screen body 11.

[0030] Furthermore, there are two sets of fixed blocks 21 and rotating blocks 22. The two sets of fixed blocks 21 are installed on both sides of the outer frame 1, and the two sets of rotating blocks 22 are installed on both sides of the guard plate 2. The cross-section of the rotating block 22 is "T" shaped. The rotating block 22 is rotatably connected to the surface of the rotating hole 23. The diameter of the rotating hole 23 is the same as the inner diameter of the rotating block 22. With the connection between the rotating block 22 and the rotating hole 23, the guard plate 2 can rotate around the rotating block 22 as the center. The outer diameter of the rotating block 22 is larger than the diameter of the rotating hole 23 and fits against the surface of the fixed block 21.

[0031] Furthermore, the cross-section of the spring plate 24 is U-shaped. The spring plate 24 is engaged with the surface of the slot 28. There are two sets of side plates 25 and rotating cylinders 27. The two sets of side plates 25 and rotating cylinders 27 are installed at both ends of the spring plate 24. There are two side plates 25 in each set. The side plates 25 are attached to both ends of the rotating cylinder 27. The spring plate 24 has a certain elasticity and can undergo elastic deformation. When the spring plate 24 and the slot 28 are engaged, the two sets of rotating cylinders 27 can be placed on the outer surface of the guard plate 2 and abut against it to limit the position of the guard plate 2.

[0032] Furthermore, the two ends of the connecting shaft 26 are fixedly connected to the surface of the side plate 25. The diameter of the connecting shaft 26 is the same as the inner diameter of the rotating cylinder 27. The rotating cylinder 27 is rotatably connected to the surface of the connecting shaft 26. With the connection between the side plate 25 and the connecting shaft 26, the rotating cylinder 27 can be installed. The rotating cylinder 27 can play a limiting role while generating rolling friction with the guard plate 2, making the engagement process smoother.

[0033] Furthermore, the surface of the mounting plate 13 is provided with a connecting mechanism, which includes a connecting plate 3. The connecting plate 3 is installed on the surface of the panel body 12 and the mounting plate 13. The surface of the panel body 12 is provided with a connecting groove 31 and a screw hole 34. The surface of the connecting plate 3 is provided with an insertion hole 32 and a groove 33. A fastening nail 35 is inserted and connected to the surface of the insertion hole 32. One side of the connecting plate 3 is installed on the surface of the panel body 12 through the connecting groove 31, and the other side is installed on the surface of the mounting plate 13 through the connecting groove 31.

[0034] Furthermore, the connecting plate 3 is snapped onto the surface of the connecting groove 31. There are two sets of connecting grooves 31 and screw holes 34. One set of connecting grooves 31 and screw holes 34 is opened on the surface of the panel body 12, and the other set of connecting grooves 31 and screw holes 34 is opened on the surface of the mounting plate 13. Each set of connecting grooves 31 and screw holes 34 has four holes. The set of connecting grooves 31 on the surface of the panel body 12 is opened at its four ends, while the other set of connecting grooves 31 is opened on the surfaces of the four mounting plates 13 respectively. The connecting plate 3 can be installed through the connecting grooves 31.

[0035] Furthermore, two sets of insertion holes 32 and grooves 33 are provided, with the two sets of insertion holes 32 and grooves 33 located on both sides of the connecting plate 3. The diameter of the insertion hole 32 is smaller than the diameter of the groove 33. One end of the fastening nail 35 is threaded to the surface of the screw hole 34, and the other end of the fastening nail 35 is abutted to the surface of the groove 33. The fastening nail 35 can be installed through the insertion hole 32, groove 33, and screw hole 34. The groove 33 prevents the large end of the fastening nail 35 from protruding from the surface of the connecting plate 3 and obstructing the installation of the capacitive touch screen. With the connection of the fastening nail 35, insertion hole 32, and screw hole 34, the connecting plate 3 can be installed and fixed on the surface of the connecting groove 31.

[0036] Working principle: When the capacitive touch screen is not in use, the protective plate 2 is first moved so that it rotates around the rotating block 22 and moves on the surface of the fixed block 21. The rotating block 22 rotates on the surface of the rotating hole 23. When the protective plate 2 is close to the spring plate 24, the two sets of rotating cylinders 27 are pressed and brought close together, causing the spring plate 24 to undergo elastic deformation. Then, the protective plate 2 is passed through the slot 28 through the spring plate 24 and the two sets of rotating cylinders 27, so that the spring plate 24 is engaged on the surface of the slot 28. The rotating cylinder 27 rotates on the surface of the connecting shaft 26 and abuts against the outside of the protective plate 2 during the movement. Thus, the protective plate 2 is limited and installed on the surface of the outer frame 1 and covers and protects the exposed area of ​​the screen body 11.

[0037] When the mounting plate 13 is damaged and needs to be replaced, first align the new mounting plate 13 with the connecting groove 31 on the panel body 12, and then snap the connecting plate 3 onto the surface of the two sets of connecting grooves 31. At this time, the holes of the insertion hole 32 and the screw hole 34 are aligned. Then, insert the fastening nail 35 into the insertion hole 32 and turn it with a Phillips screwdriver so that the small end of the fastening nail 35 is connected to the surface of the screw hole 34 through the thread, while the large end abuts against the surface of the groove 33. Then, the new mounting plate 13 can be installed and fixed on the surface of the panel body 12 through the connecting plate 3.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
