[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-4 This utility model provides a fixing device for a notebook touchpad, including a fixing frame 1 and a touchpad body 2. Both sides of the inside of the fixing frame 1 are fixedly connected to intermediate support plates 4. A transmission cavity 19 is formed on one side of the connection between the two intermediate support plates 4 and the fixing frame 1. An installation cavity 15 is formed between the two intermediate support plates 4. A fixing mechanism for fixing the touchpad body 2 is provided inside the two transmission cavities 19. A trapezoidal block 3 is fixedly connected to one side of the touchpad body 2.

[0020] See Figure 2 , Figure 3 and Figure 4 Furthermore, each of the four corners of the fixed frame 1 is fixedly connected with a connecting hole 17, and each of the two intermediate support plates 4 has a sliding groove 18 in the middle. The fixing mechanism includes a screw seat 5, a rotating seat 10, and a worm gear support plate 13. A transmission screw 6 is rotatably connected inside the screw seat 5, and a driven gear 7 is fixedly connected to one end of the transmission screw 6. A locking plate assembly is slidably connected inside the sliding groove 18. The locking plate assembly includes a limiting locking plate 8, one end of which has a threaded hole 16. Limiting blocks 9 are fixedly connected to both sides of one end of the limiting locking plate 8. The surface of the limiting locking plate 8 is flush with the inner wall of the sliding groove 18. The sliding connection is provided. The threaded hole 16 is threadedly connected to the transmission screw 6. A worm gear 11 is rotatably connected to one side of the rotating seat 10. A transmission gear 12 is fixedly connected to one side of the worm gear 11. One side of the transmission gear 12 meshes with one side of the driven gear 7. One side of the worm support plate 13 extends to the outside of the fixed frame 1 and is rotatably connected to the transmission worm 14. One end of the transmission worm 14 is fixedly connected to the drive handle. One side of the transmission worm 14 meshes with one side of the worm gear 11. The trapezoidal block 3 is set inside the mounting cavity 15. The surfaces of the two limiting plates 8 are in contact with the surface of the trapezoidal block 3.

[0021] In use, the trapezoidal block 3 is aligned with the mounting cavity 15 and inserted. Then, the drive handle is rotated to drive the transmission worm gear 14 to rotate. The rotation of the transmission worm gear 14 drives the worm wheel 11 to rotate. The rotation of the worm wheel 11 causes the transmission gear 12 to rotate. The rotation of the transmission gear 12 drives the driven gear 7 and the transmission screw 6 to rotate. The threaded hole 16 on the limiting plate 8 is threadedly connected to the transmission screw 6. At the same time, the limiting plate 8 is slidably connected to the inside of the sliding groove 18. Therefore, the limiting plate 8 moves towards the trapezoidal block 3. The position where the limiting plate 8 contacts the waist of the trapezoidal block 3 is rounded. The rounded corners of the limiting plates 8 on both sides abut against the inclined surface of the trapezoidal block 3, which can generate clamping force and pressing force on the trapezoidal block 3. In addition, the screw, worm wheel 11 and transmission worm gear 14 have self-locking characteristics, which can ensure the stability of the touch panel 2.

[0022] In this embodiment, the trapezoidal block 3 is attached to the touchpad body 2 by adhesive. The speed and accuracy of the adhesive bonding can be improved by designing an adhesive mold. The outer dimensions of the trapezoidal block 3 are the same as the dimensions of the mounting cavity 15, which is rectangular. Before placing the trapezoidal block 3 into the mounting cavity 15, the limiting plate 8 is entirely inside the sliding groove 18. After placing the trapezoidal block 3 into the mounting cavity 15, one side of the transmission worm gear 14 can be rotated first. The rotation of the transmission worm gear 14 drives the worm wheel 11 and the transmission gear 12 to rotate. The rotation of the transmission gear 12 drives the driven gear 7 and the transmission screw 6 to rotate, causing the limiting plate 8 to move towards the trapezoidal block 3. This can be achieved by first rotating one side... The limiting components provide initial positioning, and then all the limiting components on both sides are tightened. This provides stable positioning for the trapezoidal block 3. The limiting block 9 prevents the threaded hole 16 from disengaging from the transmission screw 6, thus preventing the limiting plate 8 from falling off. After rotating to a certain position, the limiting block 9 is locked onto the middle support plate 4 and will not continue to move towards the mounting cavity 15. In the direction of the transmission cavity 19, the deepest part of the threaded hole 16 abuts against the end of the transmission screw 6, and the movement naturally stops. The threaded hole 16 has a certain depth, which ensures that the movement of the limiting plate 8 can be realized. The operation is convenient and quick, which can greatly improve the installation efficiency of the touch panel 2 and the efficiency of laptop assembly.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
