Description

Technical Field

[0001] This utility model relates to the field of touchpad bracket technology, specifically a touchpad bracket structure for a laptop computer. Background Technology

[0002] The user experience of a laptop touchpad is greatly influenced by the support structure beneath it. A typical touchpad support structure includes a rectangular support ring, an inner support spring, and a reinforcing plate. Localized stress concentration during the stamping process of the rectangular support ring can lead to deformation and low yield rates; the numerous welded points on the components increase the risk of thermal deformation; and the touchpad feels stiff when pressed with a finger. To address these issues, this invention provides a touchpad support structure for laptops. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a touchpad support structure for a laptop computer. This structure features an arc-shaped protrusion along the long side of a rectangular support ring and a pressure protrusion on the inner side of the short side. This design reduces deformation and increases the strength of the rectangular support ring, allowing for faster force transmission when the finger presses, thus improving the touchpad button operation feel. Furthermore, due to the improved design of the rectangular support ring, it has sufficient strength, eliminating the need for screws in the middle of the straight section, reducing laser welding positions, and lowering the area of ​​the welding heat-affected zone. This solves the technical problems mentioned in the background section.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a touchpad bracket structure for a laptop computer, comprising: a rectangular support ring, an inner support spring, and two reinforcing plates; the inner side of the long side of the rectangular support ring is provided with an inwardly convex arc-shaped protrusion, and the inner side of the short side of the rectangular support ring is provided with a pressing protrusion; the inner support spring includes two H-shaped base plates connected by a straight piece, and the two ends of the straight piece are respectively connected to the horizontal pieces of the two H-shaped base plates; the ends of the two vertical pieces of the H-shaped base plates are connected to the inner side of the short side of the rectangular support ring, and the other ends of the two vertical pieces of the H-shaped base plates are fixedly connected to the touchpad control board by screws; the reinforcing plates are fixedly installed on the bottom surface of the H-shaped base plates.

[0005] Preferably, the long side width of the rectangular support ring is 1.5-2.5mm, and the radius of curvature of the arc-shaped protrusion is R = 393+5 / -5mm.

[0006] Preferably, the pressing protrusion and the short side of the rectangular support ring form a pressing plane with a width of 3-6mm.

[0007] Preferably, the reinforcing sheet includes an integrally connected U-shaped sheet and an isosceles trapezoidal sheet, wherein the isosceles trapezoidal sheet is integrally connected to the outer side of the U-shaped sheet.

[0008] Preferably, the screw is threadedly connected to a nut welded to a corresponding position on the back of the touchpad control panel.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention features an arc-shaped protrusion on the long side of a rectangular support ring and a pressing protrusion on the inner side of the short side. This design reduces deformation and increases the strength of the rectangular support ring, allowing for faster force transmission when the finger presses, thus improving the touchpad button operation feel. Furthermore, due to the improved design of the rectangular support ring, it has sufficient strength, eliminating the need for screws in the middle of the flat plate, reducing laser welding positions, decreasing the area of ​​the welding heat-affected zone, and improving the smoothness of the touchpad button operation force curve, thereby enhancing the operation feel.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] like Figures 1 to 4 As shown, this embodiment provides a touchpad support structure for a laptop computer, including: a rectangular support ring 1, an inner support spring 2, and two reinforcing plates 3; the inner side of the long side of the rectangular support ring 1 is provided with an inwardly convex arc-shaped protrusion 11; specifically, the width of the long side of the rectangular support ring 1 is 1.5-2.5mm, and the radius of curvature of the arc-shaped protrusion 11 is R=393+5 / -5mm; this makes the punching force evenly distributed along the arc surface, reduces the stress per unit area, and is not easily deformed. The inner side of the short side of the rectangular support ring 1 is provided with a pressing protrusion 12; the pressing protrusion 12 and the short side of the rectangular support ring 1 form a pressing plane with a width of 3-6mm. The arc-shaped protrusion 11 on the long side of the rectangular support ring 1 and the pressing protrusion 12 on the inner side of the short side increase the strength of the rectangular support ring 1, and the force transmission is faster when the finger is pressed, thereby improving the drawback of the stiff feel of the touchpad button operation.

[0020] The inner support spring 2 includes two H-shaped base plates 22 connected by a straight piece 21. The two ends of the straight piece 21 are connected to the horizontal pieces of the two H-shaped base plates 22 respectively. The ends of the two vertical pieces of the H-shaped base plates 22 are connected to the inner side of the short side of the rectangular support ring 1. The other ends of the two vertical pieces of the H-shaped base plates 22 are fixedly connected to the touch panel control board by screws 4. Specifically, the screws 4 are threadedly connected to nuts welded to corresponding positions on the back of the touch panel control board. The reinforcing piece 3 is fixedly installed on the bottom surface of the H-shaped base plate 22. Specifically, the reinforcing piece 3 includes an integrally connected U-shaped piece and an isosceles trapezoidal piece. The isosceles trapezoidal piece is integrally connected to the outer side of the U-shaped piece. The U-shaped piece corresponds to the position of the H-shaped base plate 22, and the isosceles trapezoidal piece corresponds to the position of the straight piece 21. In the existing design, due to insufficient strength of the rectangular support ring 1, the middle position of the straight piece 21 needs to be fixedly connected to the touch panel control board by screws 4, that is, the corresponding position of the touch panel control board needs to be laser welded; however, in this embodiment, the rectangular support ring 1 is improved and has sufficient strength, so the middle position of the straight piece 21 does not need to be fixed by screws 4, reducing the laser welding position, reducing the area of ​​the welding heat-affected zone, improving the smoothness of the touch panel key operation force curve, and improving the operation feel.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
