Description

Technical Field

[0001] This utility model relates to the field of touch panels, and in particular to a novel touch panel glass button product. Background Technology

[0002] In the 5G era, smart touch screens and customer information input are all tablet touch screens, which have the characteristics of multi-touch, fast response time, long service life and thin and light structure. However, as a human-computer interaction tool, the biggest problem with touch interfaces is that they do not have a real operating feel. They cannot provide the strong feedback and response of a real keyboard. This is fatal for blind people or people with poor eyesight, who are basically unable to interact effectively.

[0003] The biggest problem with touch panels is the lack of tactile feedback, unlike a physical keyboard. This makes it difficult for visually impaired users to perceive button locations and interact effectively. Furthermore, actual product testing revealed an unreasonable distance between adjacent glass buttons; the actual distance between two buttons was too small, and the warping of the button glass affected adjacent buttons. Excessive warping and deformation of the button glass caused malfunctions in surrounding buttons, with some buttons failing to spring back after being pressed. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of touch panel glass button product to solve the problem that the touch panel button glass does not bounce back after being pressed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel touch panel glass button product, comprising a first glass substrate, a first optical adhesive layer, a second glass substrate, a second optical adhesive layer and a touch panel stacked sequentially;

[0006] The first glass substrate is provided with a plurality of button components evenly spaced along the longitudinal direction, and each button component includes a plurality of button units evenly spaced along the transverse direction.

[0007] Each button unit includes a button area and a rigid area. The rigid area is integrally formed on the first glass substrate. The surface of the rigid area near the touch panel is coplanar with the surface of the first glass substrate near the touch panel. A receiving cavity is formed in the middle of the rigid area. The button area is integrally formed inside the receiving cavity. The rigid area protrudes from the surface of the first glass substrate away from the touch panel. A button protrusion is formed on the surface of the button area away from the touch panel. The button protrusion protrudes from the surface of the rigid area away from the touch panel. A vacuum groove is formed on the surface of the button area near the touch panel. The button protrusion, the vacuum groove, and the first optical adhesive layer are sequentially connected.

[0008] Preferably, the spacing between two adjacent button components is set to Y millimeters, where Y satisfies the following relationship: Y∈[5.3, 10.3].

[0009] Preferably, the spacing between two adjacent button units in the same button assembly is set to X millimeters, where X satisfies the following relationship: X∈[4.3, 10.3].

[0010] Preferably, the length a mm of the button unit and the width b mm of the button unit satisfy the following relationship: a∈[10.3, 13.7], b∈[7.36, 9.4].

[0011] Preferably, the edge of the bottom of the vacuum tank is coplanar with the surface of the rigid area near the touch panel.

[0012] Preferably, the button area has the degree of freedom to elastically deform toward the second glass substrate, and the button protrusion elastically deforms under pressure, thereby reducing the depth of the vacuum groove.

[0013] Preferably, the rigid region is a rounded square frame, the rigid region is integrally formed with the first glass substrate, and the rigid region is bonded to the second glass substrate by a first optical adhesive layer.

[0014] Preferably, both the button area and the receiving cavity are rounded rectangles or circles.

[0015] Preferably, both the button protrusion and the vacuum groove are rounded rectangles or circles.

[0016] Preferably, the raised surface of the button is provided with raised text markings.

[0017] The beneficial effects of this utility model are as follows: two adjacent button areas are separated by the sides of two rigid areas. The rigid areas reduce the influence of warping from adjacent button units, solve the problem of the glass of the touch panel button area not springing back when pressed, and also improve the product yield.

[0018] The accompanying drawings further illustrate the present invention, but the embodiments in the drawings do not constitute any limitation on the present invention.

[0020] Figure 2 This is a schematic diagram of a structure provided for an embodiment of the present utility model;

[0021] In the figure, the markings are: 1: First glass substrate; 2: Button assembly; 3: Button unit; 4: Rigid area; 5: Button area; 6: Button protrusion; 7: Vacuum groove; 8: Second glass substrate; 9: Touch panel. Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] It should be noted that, in this utility model, unless otherwise stated, when an element is referred to as "connected to" or "set on" another element, it can be directly on the other element or may have an intervening element present simultaneously. "Inner" and "outer" refer to the inner and outer contours of a specific part. "Far" and "near" refer to the far and near relative to a certain component.

[0024] like Figures 1-2 As shown in the figure, a novel touch panel glass button product provided by an embodiment of the present invention includes a first glass substrate 1, a first optical adhesive layer, a second glass substrate 8, a second optical adhesive layer and a touch panel 9 stacked in sequence;

[0025] The first glass substrate 1 is provided with a plurality of button components 2 evenly spaced along the longitudinal direction, and each button component 2 includes a plurality of button units 3 evenly spaced along the transverse direction.

[0026] Each button unit 3 includes a button area 5 and a rigid area 4. The rigid area 4 is integrally formed on the first glass substrate 1. The surface of the rigid area 4 near the touch panel 9 is coplanar with the surface of the first glass substrate 1 near the touch panel 9. A receiving cavity is formed in the middle of the rigid area 4, and the button area 5 is integrally formed inside the receiving cavity. The rigid area 4 protrudes from the surface of the first glass substrate 1 away from the touch panel 9. A button protrusion 6 protrudes from the surface of the button area 5 away from the touch panel 9. A vacuum groove 7 is recessed from the surface of the button area 5 near the touch panel 9. The button protrusion 6, the vacuum groove 7, and the first optical adhesive layer are sequentially connected. The rigid area cannot be pressed. When the button area is pressed, the rigid area improves the tactile feedback, making it easier for visually impaired people to use.

[0027] The spacing between two adjacent button components 2 is set to Y millimeters, where Y millimeters satisfies the following relationship: Y∈[5.3, 10.3]. This is to avoid two adjacent button components 2 being too close together, which could cause mutual interference between the button components 2.

[0028] The spacing between two adjacent button units 3 in the same button assembly 2 is set to X millimeters, where X satisfies the following relationship: X∈[4.3, 10.3]. This avoids two adjacent button units 3 being too close, which could cause mutual interference between the button units 3 and affect the warpage.

[0029] The length *a* mm and width *b* mm of the button unit 3 satisfy the following relationship: *a* ∈ [10.3, 13.7], *b* ∈ [7.36, 9.4]. The length *a* mm and width *b* mm of the button unit 3 are further preferably: *a* = 13.3, *b* = 7.38. The dimensions of the button unit 3, combined with the spacing between adjacent button units 3, ensure smooth button operation.

[0030] In this embodiment, two rows of button assemblies 2 are provided on the first glass substrate 1. Each row of button assemblies 2 consists of 3 button units 3, for a total of 6 button units 3 across the two rows. The length and width dimensions of the button unit 3 are set to 7.38mm * 13.3mm. Under the condition that the length, width, and thickness dimensions of the button unit 3 are fixed, a Design of Existing Dimensions (DOE) experiment is conducted with the lateral spacing X and the vertical spacing Y of the button unit 3 as variations to obtain a reasonable design spacing.

[0031] The experimental values ​​for the horizontal spacing X and the vertical spacing Y are shown in the table below:

[0032] The experimental results are as follows, where "●" indicates defective products with malfunctioning buttons, and "★" indicates good products with normal button function:

[0033] Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y8 Y9 Y10 X1 ● ● ● ● ● ● ● ● ● ● X2 ● ● ● ● ● ● ● ● ● ● X3 ● ● ● ● ● ● ● ● ● ● X4 ● ● ● ● ● ● ★ ★ ★ ★ X5 ● ● ● ● ● ★ ★ ★ ★ ★ X6 ● ● ● ● ● ★ ★ ★ ★ ★ X7 ● ● ● ● ● ★ ★ ★ ★ ★ X8 ● ● ● ● ★ ★ ★ ★ ★ ★ X9 ● ● ● ● ★ ★ ★ ★ ★ ★ X10 ● ● ● ● ★ ★ ★ ★ ★ ★

[0034] Based on experimental data, increasing the distance between the buttons can solve the problem of abnormal button functions caused by the large deformation of the glass. However, too large a distance is not aesthetically pleasing and the buttons are not easy to use. In actual product design, considering the product appearance and ease of use, X is preferably 4.3mm and Y is preferably 9.3mm.

[0035] The bottom edge of the vacuum groove 7 is coplanar with the surface of the rigid region 4 near the touch panel 9. The rigid region 4 is located on the second glass substrate 8 and cannot be deformed or pressed, thus improving tactile feedback.

[0036] The button area 5 has the degree of freedom to elastically deform toward the second glass substrate 8. When the button protrusion 6 is subjected to pressure, it elastically deforms, thereby reducing the depth of the vacuum groove 7. When the button area 5 is pressed, the button area 5 deforms inward, and the vacuum groove 7 shrinks, triggering a conductive path.

[0037] The rigid region 4 is a rounded square frame, integrally formed with the first glass substrate 1, and bonded to the second glass substrate 8 by a first optical adhesive layer. The rigid region 4 surrounds the button area 5, separating the button area 5 from other button units around it.

[0038] In one embodiment, both the button area 5 and the receiving cavity are circular, and both the button protrusion 6 and the vacuum groove 7 are circular. The button is a circular button.

[0039] In one embodiment, both the button area 5 and the receiving cavity are rounded rectangles, and both the button protrusion 6 and the vacuum groove 7 are rounded rectangles. The button is a rounded rectangle button.

[0040] In one embodiment, both the button area 5 and the receiving cavity are rounded rectangles, and both the button protrusion 6 and the vacuum groove 7 are circular. The button has a rounded rectangular outer surface and a circular vacuum groove inside, reducing manufacturing difficulty.

[0041] In one embodiment, the surface of the button protrusion 6 is provided with raised text markings. This allows for the creation of Braille on the button protrusion 6 using chemical etching, enabling blind and visually impaired individuals to use the touch panel 9.

[0042] The technical features of the embodiments described above can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these should all be considered to be within the scope of this specification.
