The invention provides a touch panel that does not need to be equipped with a spring, and can simultaneously meet the correctness of the pen touch panel sensing when the consumer presses. This saves manufacturing costs while reducing process steps. See Figure 1 and Figure 2. FIG. 1 is a perspective view showing the touch panel 100 combined with the upper cover 510 of the notebook according to an embodiment of the invention. 2 is a view showing the explosion of the touch panel 100 of FIG. Figure. The touch panel 100 is applied to a notebook. The notebook has an upper cover 510. The upper cover 510 has an opening 520. The touch panel 100 includes a connection portion 110 and a support plate 120. The connecting portion 110 is connected to the bottom surface 512 of the upper cover 510 (see Fig. 4). The support plate 120 includes a body 124 and an upper stop 130. The body 124 is connected to the connecting portion 110.

See Figure 2 and Figure 3. Figure 3 is a cross-sectional view along line 3-3' of the touch panel of Figure 2; The first vertical projection of the body 124 relative to the bottom surface 512 is located within the opening 520. The upper stop portion 130 is coupled to the body 124. The second vertical projection of the upper stop 130 relative to the bottom surface 512 at least partially overlaps the bottom surface 512. Therefore, if the support plate 120 moves upward, the upper stop portion 130 abuts against the bottom surface 512 to limit the support plate 120, and at the same time limits the deformation of the touch panel 100. Therefore, the touch panel 100 is not easily damaged by the original interference due to deformation. .

When the touch panel 100 uses the plastic support plate 120 to omit the design of the spring, it is necessary to consider the problem that the plastic itself is deformed due to aging. Therefore, the support plate 120 is designed with an upper stop portion 130 to limit the upward deformation of the support plate 120 due to aging. Therefore, even if the touch panel 100 has aged, the touch panel 100 can still be correctly sensed, and the user feels that the shape of the touch panel 100 is still flat.

See Figure 2, Figure 5, and Figure 6. Figure 5 is a cross-sectional view along line 5-5' of the touch panel 100 of Figure 1. FIG. 6 is a perspective view of the touch panel 100 in accordance with an embodiment of the present invention. The touch panel 100 includes a sensing module 160. The sensing module 160 covers and connects the body 124 and is located within the opening 520. The opening 520 has a first edge 530 and a second edge 540. The touchpad 100 further includes a spring arm 140 coupled to the bottom surface 512. The connecting portion 110 and the elastic arm 140 extend from the first edge 530 and the second edge 540 to a region within the opening 520, respectively.

Therefore, when the user presses the left button 162 or the right button 164, the elastic support can be felt underneath, so that the operation is more sensitive.

See Figure 4, Figure 5, and Figure 6. 4 is a cross-sectional view of the touch panel 100 along the line 4-4' along the line 1 (the arm 142 is not shown). The elastic arm 140 includes a cantilever 142 and a convex portion 144. The cantilever 142 is coupled to the bottom surface 512. The protrusion 144 connects the cantilever 142. The protrusion 144 abuts against the sensing module 160. The elastic arm 140 further includes a cantilever 142 and a convex portion 144. The cantilever 142 provides the resilient force and the projection 144 is used to constantly abut the sensing module 160. Therefore, when the user presses the sensing module 160 in the direction 300, the user feels that the force of the rebound is continuous, so the user feels better when pressing the sensing module 160.

The touch panel 100 includes a lower stop 150. The lower stop portion 150 connects the bottom surface 512 and extends to an area within the opening 520. The sensing module 160 further covers the lower stop 150. The lower stopper portion 150 is located at a position relative to the left key 162 and the right key 164 (see Fig. 2). The lower stop portion 150 is used to prevent the user from pressing excessively when pressing the sensing module 160, thereby causing the touch panel 100 or Damage to other components.

See Figure 2, Figure 5, and Figure 6. The number of upper stops 130 is two and is located on both sides of the body 124. When the user presses the left button 162 or the right button 164, regardless of whether the left button 162 or the right button 164 is pressed, when the support plate 120 is bounced, the upper stopper portion 130 can prevent the support plate 120 from excessively bouncing upward.

The connecting portion 110 and the elastic arm 140 are connected to the lower stopper portion 150 to form a frame body 180. In the present invention, the connecting portion 110 is designed, and the elastic arm 140 is connected to the lower stopper portion 150 to form the frame body 180. Therefore, only one mold press molding is required to produce the touch panel 100. In addition, when the touch panel 100 is assembled to the notebook, it is not necessary to assemble all the components one by one, and the assembly procedure is largely saved.

See Figure 6. The touch panel 100 includes a support rib 152 coupled to the lower stop portion 150 for reinforcing the pressure that the lower stop portion 150 can withstand. The touch panel 100 includes a rib 170 connected to the frame 180. The rib 170 is located between the connecting portion 110 and the lower stop portion 150 for assisting with the pressure applied by the sensing module 160 (Fig. 4).

In summary, the touch panel of the present invention does not need to be equipped with a spring, and can simultaneously meet the correctness of the pen touch panel sensing when the consumer presses. The touch panel of the present invention has the upper stop portion abutting the bottom surface to limit the movement of the support plate, and at the same time limits the deformation of the touch panel, so that the touch panel is not easily damaged by the original member due to deformation. Furthermore, when the touch panel uses a plastic support plate to omit the design of the spring, it is necessary to consider the problem that the plastic itself is deformed due to aging. Therefore, the support plate is designed with an upper stop to limit the upward deformation of the support plate due to aging. So even if the trackpad is aging, the trackpad is still However, the correct sensing can make the user feel that the shape of the touchpad is still flat.
