Description

Technical Field

[0001] This utility model relates to the field of computer functional components, and in particular to a lightweight touchpad module with adjustable pressing feel. Background Technology

[0002] A touchpad is a widely used tactile input device on laptops. Users move their fingers across the surface or press buttons to control the cursor on the screen and input information. Traditional touchpads typically place the pressing area in the lower center. This requires additional reinforcement of the pressing area in the design, resulting in a thicker overall touchpad. Furthermore, the pressing position is limited, and the feedback force varies depending on the location within the same area, leading to inconsistent and unstable performance. Additionally, it places high demands on the deformation and automatic reset capabilities of the support plate for the pressing area. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a lightweight touchpad module with adjustable pressing feel, which can improve the lightweight level of the touchpad module while adjusting the pressing feel as needed.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A lightweight touchpad module with adjustable pressing feel is provided. The lightweight touchpad module is assembled from a front panel, a PCB circuit board, a support plate, and a bottom frame stacked sequentially from top to bottom. A function button is provided in the middle of the PCB circuit board. A button hole is provided in the middle of the support plate corresponding to the position of the function button. Circuit clearance holes are symmetrically arranged on both sides of the button hole. The bottom frame is a rectangular hollow frame structure, and a shaping plate is provided in the middle of the bottom frame. The two ends of the shaping plate are respectively connected to the bottom frame. The midpoints of the two long side frames are connected. An adjustable travel top support mechanism is installed in the middle of the shaping plate. A top plate is provided at the top center of the adjustable travel top support mechanism. The top plate is located directly below the key hole. The size of the top plate is smaller than the size of the key hole. Multiple locking holes are symmetrically arranged on the two short side frames of the bottom frame. A full-area elastic support component is also provided between the support plate and the bottom frame. There are two full-area elastic support components symmetrically installed on both sides of the shaping plate, and the top of each full-area elastic support component is connected to the lower surface of the support plate.

[0005] In a preferred embodiment of this utility model, figure-eight reinforcing plates are symmetrically arranged between the two ends of the shaping plate and the two long side frames of the bottom frame.

[0006] The adjustable stroke support mechanism includes a chassis, a top plate, a threaded sleeve, an ejector screw, and an arc-shaped arch plate. The chassis is annular with multiple rivet posts evenly distributed on its back. The top plate is located in the center of the chassis, and the chassis and top plate are connected by multiple arc-shaped arch plates evenly arranged around the outer side of the top plate. A sleeve mounting hole matching the size of the threaded sleeve is provided at the center of the shaping plate. Riveting positioning holes corresponding to the rivet posts are evenly distributed around the sleeve mounting hole. During assembly, the chassis is fixed to the center of the shaping plate by the multiple rivet posts. At this time, the top plate is directly above the sleeve mounting hole, the threaded sleeve is installed in the sleeve mounting hole, and the ejector screw is installed in the threaded sleeve, enabling the top plate to be ejected upwards as needed. A PET buffer pad is adhered to the top plate, and the size of the PET buffer pad is not larger than the size of the key hole.

[0007] The full-area elastic support component is a stainless steel spring sheet, including a connecting plate, positioning corner plates, inner support arms, and diagonal support arms. The upper surface of the connecting plate is fixed to the lower surface of the support plate. There are two positioning corner plates, which are fixed to the two top corners on the corresponding side of the back of the bottom frame. Each positioning corner plate is connected to the connecting plate by a diagonal support plate. There are two inner support arms, which are arranged inside the connecting plate and extend symmetrically to the two long side frames of the bottom frame. The upper surface of the inner support arm is connected to the lower surface of the support plate. The top of the inner support arm is provided with a support foot near the end of the long side frame. The support foot is fixedly connected to the foot platform arranged one-to-one on the inner side of the two long side frames.

[0008] The beneficial effects of this utility model are as follows: This utility model optimizes the structure of existing laptop touchpad modules. By using a rectangular hollow frame structure as the bottom frame instead of a traditional bottom plate, the overall weight is significantly reduced. Furthermore, placing the press function key in the center of the touchpad module further improves the structural compactness of the entire module without affecting trajectory input, thus further enhancing the overall lightweight level of the module. In addition, by arranging a full-area elastic support component between the bottom frame and the support plate, the panel is provided with full-area elastic support. This ensures that when any point on the panel is subjected to force, the pressure is evenly transmitted to the entire panel. In other words, pressing any point on the panel provides the same pressing force to the central press function key, not only expanding the area for pressing functions but also providing uniform tactile force and sensitive signal feedback. An adjustable travel support mechanism is provided below the press function key, which can control the tactile feedback force by adjusting the ejection travel, making the pressing feel more comfortable.

[0023] Please see Figures 1 to 7 The embodiments of this utility model include:

[0024] A lightweight touchpad module with adjustable pressing feel is disclosed. The lightweight touchpad module is assembled from a panel 1, a PCB circuit board 2, a support plate 3, and a bottom frame 4 stacked sequentially from top to bottom. The PCB circuit board 2 has a function button in the center. The support plate 3 has a button hole 601 in the center corresponding to the function button position, and circuit clearance holes 302 on both sides of the button hole 601. The bottom frame 5 is a rectangular hollow frame structure, with a shaping plate 501 in the center. The two ends of the shaping plate 501 are connected to the midpoints of the two long sidewalls of the bottom frame 5, respectively. An adjustable travel support mechanism is installed in the middle. A top plate 602 is provided at the center of the top of the adjustable travel support mechanism. The top plate 602 is located directly below the button hole 301. The size of the top plate 602 is smaller than the size of the button hole 301. Four locking holes 504 are symmetrically arranged on the two short side edges of the bottom frame 4. A full-area elastic support component is also provided between the support plate 3 and the bottom frame 4. There are two full-area elastic support components symmetrically installed on both sides of the shaping plate 501, and the top of each full-area elastic support component is connected to the lower surface of the support plate 3.

[0025] The shaping plate 501 is symmetrically arranged with figure-eight reinforcing plates 502 between its two ends and the two long sidewalls of the base frame 5. By setting the figure-eight reinforcing plates 502 together with the shaping plate 501 to form a shaping support, they can work together to improve the stress stability of the entire base frame 5 and prevent the entire base frame 5 from deforming under stress.

[0026] The adjustable stroke support mechanism includes a chassis 603, a top plate 602, a threaded sleeve 601, an ejector screw 606, and an arc-shaped arch plate 604. The chassis 603 is annular with three evenly distributed riveting posts 605 on its back. The top plate 602 is located in the middle of the chassis 603. The chassis 603 and the top plate 602 are connected by three evenly distributed arc-shaped arch plates 604 on the outer side of the top plate 602. The center position of the shaping plate 501 is set to match the size of the threaded sleeve 601. The matching sleeve mounting hole is surrounded by riveting positioning holes 505, each corresponding to a riveting post 605. During assembly, the base plate 603 is fixed in the middle of the shaping plate 501 by three riveting posts 605. At this time, the top plate 602 is located directly above the sleeve mounting hole. The threaded sleeve 601 is installed in the sleeve mounting hole, and the ejector screw 606 is installed in the threaded sleeve 601, which can push the top plate 602 upward as needed. In this way, during actual assembly, the ejection height of the ejector screw 606 can be adjusted according to the required tactile feedback force when pressing the touchpad, pushing the top plate 602 into the button hole 301, and directly abutting against the function button on the PCB circuit board 2 without affecting the support performance of the surrounding all-area elastic support components.

[0027] A PET buffer pad 607 is adhered to the top plate. The size of the PET buffer pad 607 is not larger than the size of the button hole 301. By adhering the PET buffer pad 607 to the top plate 602, the adjustment stroke range of the ejector screw 606 is increased. On the other hand, it replaces the top plate 602 in direct contact with the function button, reducing the direct impact when pressed and minimizing damage to the function button.

[0028] The full-area elastic support component is a stainless steel spring sheet made of 304 stainless steel, including a connecting plate 401, a positioning corner plate 405, an inner support arm 402, and a diagonal support arm 403. The upper surface of the connecting plate 401 is bonded and fixed to the lower surface of the support plate 3. There are two positioning corner plates 405, which are fixed to the two top corners of the corresponding side of the back of the bottom frame 5. Each positioning corner plate 405 is connected to the connecting plate 401 by a diagonal support plate 403. There are two inner support arms 402, which are arranged inside the connecting plate 401 and extend symmetrically to the two long side frames of the bottom frame 5. The upper surface of the inner support arm 402 is bonded and fixed to the lower surface of the support plate 3. The top of the inner support arm 402 is provided with a support foot 404 near the end of the long side frame. The support foot 404 is bonded and fixed to the foot platform 503 arranged one-to-one on the inner side of the two long side frames. The full-area elastic support component is made of stainless steel and has good elastic deformation capability. It is symmetrically installed between the support plate 3 and the bottom frame 5. On the one hand, the structural strength of the four top corners of the bottom frame 5 can be strengthened by the positioning corner plate 405, which enhances the structural stability of the bottom frame 5 under stress. On the other hand, the two full-area elastic support components support the entire space between the support plate 3 and the bottom frame 5 on both sides of the shaping plate 501. While facilitating the installation of the adjustable stroke top support mechanism, it also creates full-area elastic support for the entire module. In this way, pressing any point on the panel 1 will provide the same pressing force to the function button in the middle, with uniform tactile force and sensitive and accurate signal feedback.
