[0027] See also Figures 1 to 3 A touch panel comprises a substrate 1, a cover plate 2, a touch sensing spring 3 and a circuit board 4; the substrate 1 is provided with a mounting hole 11, the mounting hole 11 has a first through-opening 111 and a second through-opening 112 which are arranged opposite to each other, the area of the first through-opening 111 is smaller than the area of the second through-opening 112, and the mounting hole 11 is tapered; the cover plate 2 is arranged on the substrate 1; the touch sensing spring 3 is arranged on the mounting hole 11, one end of the touch sensing spring 3 extends out of the first through-opening 111, and the end of the touch sensing spring 3 extending from the first through-opening 111 abuts against the cover plate 2; the circuit board 4 is arranged on a side of the substrate 1 away from the cover plate 2, the other end of the touch sensing spring 3 away from the cover plate 2 is connected to the circuit board 4, and the circuit board 4 covers the second through-opening 112.
[0028] For the touch panel, the touch sensing spring 3 is arranged in the mounting hole 11, and one end of the touch sensing spring 3 extends out of the first through hole 111, so that the gap between the touch sensing spring 3 and the first through hole 111 can be made smaller, thereby reducing the gap between the touch sensing spring 3 and the mounting hole 11, thereby reducing the deflection of the touch sensing spring 3 in the mounting hole 11, and improving the assembly efficiency; and when the touch sensing spring 3 is deflected in the mounting hole 11, the touch sensing spring 3 can quickly abut against the wall surface of the first through hole 111, so that the deflected part of the touch sensing spring 3 is driven to reset under the force generated by the wall surface of the first through hole 111; at the same time, the touch sensing spring 3 is arranged in the mounting hole 11, and The other end of the touch sensing spring 3 away from the cover plate 2 is located at the second opening 112, so that the gap between the touch sensing spring 3 and the second opening 112 can be larger, thereby increasing the gap between the touch sensing spring 3 and the mounting hole 11, thereby improving the alignment degree of the touch sensing spring 3 extending from the second opening 112 into the mounting hole 11, and improving the assembly efficiency; and when the touch sensing spring 3 extends into the mounting hole 11 from the second opening 112, if the touch sensing spring 3 contacts the tapered inner wall of the mounting hole 11 due to inaccurate positioning, the touch sensing spring 3 can be guided by the tapered inner wall of the mounting hole 11 and move through the first opening 111 along the tapered inner wall of the mounting hole 11, thereby automatically correcting the touch sensing spring 3, so that the touch sensing spring 3 can be smoothly assembled in the mounting hole 11.
[0029] Regarding the above-mentioned mounting hole 11, it can be understood that the mounting hole 11 is at least partially tapered, or the mounting hole 11 is tapered as a whole. It can also be understood that the cross-sectional shape of the mounting hole 11 is adapted to the cross-sectional shape of the touch sensing spring 3, that is, the cross-sectional shape of the mounting hole 11 along the height direction is the same as the cross-sectional shape of the touch sensing spring 3 along the height direction.
[0030] For mounting hole 11 above, see Figures 3 to 5 The mounting hole 11 includes a first hole body 113 and a second hole body 114, the first hole body 113 is connected to the second hole body 114, the first hole body 113 is tapered, the second hole body 114 is columnar, the side of the first hole body 113 away from the second hole body 114 is connected to the first through opening 111, and the side of the second hole body 114 away from the first hole body 113 is connected to the second through opening 112.

By satisfying that D1 is less than or equal to 0.4 mm, the touch sensing spring 3 can at least partially reduce the gap with the mounting hole 11, so that the mounting hole 11 at least partially maintains a small gap with the touch sensing spring 3. By satisfying that D2 is less than or equal to 1.5 mm, the touch sensing spring 3 can at least partially increase the gap with the mounting hole 11, so that the mounting hole 11 at least partially maintains a large gap with the touch sensing spring 3.
[0032] For the above touch panels, see Figure 2 and Figure 3 There are multiple mounting holes 11 and multiple touch sensing springs 3 , one touch sensing spring 3 is arranged in one mounting hole 11 , one end of multiple touch sensing springs 3 abuts against the cover plate 2 , and the other ends of multiple touch sensing springs 3 are connected to the circuit board 4 .

[0036] For the above touch panels, see Figures 3 to 5 , the cover plate 2 is made of transparent material. Through the above method, the light-emitting components can penetrate the cover plate 2.
