Figure 1 is a three-dimensional schematic view of the electronic device 100 according to an embodiment of the present disclosure, Figure 2 is an exploded schematic view of the electronic device 100 of Figure 1, and Figure 3 is a schematic view along the line 3- of Figure 1 3 is a schematic cross-sectional view of the electronic device 100. Please refer to Figures 1 to 3 together. The electronic device 100 includes a housing 110, a button 120, a light-emitting module 130, a circuit board 140, and a switch 150. For ease of description, the electronic device 100 is shown as a notebook computer in Figure 1. However, the electronic device 100 may also be a desktop computer, a tablet computer, or other devices with a housing 110, buttons 120, light-emitting modules 130, The electronic device 100 of the circuit board 140 and the switch 150 is not limited in this disclosure, and will be described first.

The housing 110 has an opening 112 and an accommodating space 114, and the accommodating space 114 is connected to the opening 112. In detail, the opening 112 is located on the outer side of the housing 110 (for example, the side close to the user), and the accommodating space 114 is located on the inner side of the housing 110 (for example, the side away from the user) to accommodate the circuit board 140, etc. Components.

The button 120 is disposed in the opening 112. The light emitting module 130 includes a light emitting source 132 and a light guide plate 134, and the light emitting module 130 is disposed in the groove 124 of the button 120. In other words, the light source 132 and the light guide plate 134 are both located in the groove 124 of the button 120. The light emitted by the light source 132 can be concentrated to the middle position of the button 120 to facilitate the operation of the user. The light-emitting source 132 may be a light-emitting diode (LED). As shown in FIGS. 2 and 3, since the light-emitting module 130 is disposed in the groove 124 of the button 120, the button 120 completely covers the light guide plate 134. In this way, the effect of avoiding light leakage can be achieved.

The circuit board 140 is disposed in the accommodating space 114. The switch 150 is disposed on the circuit board 140. The switch 150 and the light guide plate 134 are respectively located on two opposite sides of the circuit board 140. In detail, the light emitted by the light source 132 can be focused on the middle position of the button 120, and the position where the switch 150 is disposed on the circuit board 140 can correspond to the aforementioned middle position. In other words, the position of the switch 150 and the position where the light emitted by the light source 132 is focused on the button 120 are at the same horizontal position. With the aforementioned configuration, it is helpful for the user to press the middle position of the button 120 (that is, the concentrated position of the light emitted by the light-emitting source 132) to achieve the effect of consistent pressing force and feel.

In some embodiments, the electronic device 100 further includes a gel ring 160. The gel ring 160 is disposed on the outer edge 122 of the button 120. In detail, the glue ring 160 is attached to the outer edge 122 of the button 120 so that the button 120 is fixed to the circuit board 140 via the glue ring 160. In other words, the button 120 and the circuit board 140 can be connected via the gel ring 160 and can be regarded as one body. In this way, the light guide plate 134 can be sealed between the button 120 and the circuit board 140, which helps to concentrate the light and achieve the effect of no light leakage.

In some embodiments, the glue ring 160 directly contacts the button 120 and the circuit board 140 to fix the button 120 and the circuit board 140. The gel ring 160 may be designed to have a four-sided hollow shape. In some embodiments, the shape of the gel ring 160 is the same as the shape of the outer edge 122 of the button 120, which helps to achieve the effect of saving materials.

In some embodiments, the electronic device 100 further includes a supporting structure 170. The supporting structure 170 is disposed in the accommodating space 114, and the supporting structure 170 is attached to the housing 110. In some embodiments, the supporting structure 170 and the button 120 are respectively located on two opposite sides of the circuit board 140. In other words, the button 120, the light guide plate 134, and the gel ring 160 are all located on one side of the circuit board 140, and the switch 150 and the supporting structure 170 are located on the other opposite side of the circuit board 140.

In some embodiments, as shown in FIG. 3, the switch 150 is located in the gap G between the support structure 170 and the circuit board 140. One side of the switch 150 is attached to the circuit board 140, and the other side of the switch 150 is adjacent to the supporting structure 170. Since the button 120 and the circuit board 140 are connected via the gel ring 160, when the button 120 is pressed, the switch 150 contacts the support structure 170. In this way, the switch 150 is driven so that the light source 132 of the light emitting module 130 emits light. At this time, the middle position of the button 120 is the bright spot position. Furthermore, since the switch 150 is located in the gap G between the support structure 170 and the circuit board 140, no matter if the user presses the button 120 at any angle or any position, the switch 150 can contact the support structure 170, thereby triggering the light emitting mold. The light source 132 of the group 130 emits light. In other words, as long as the switch 150 contacts any point on the support structure 170, the light-emitting edge 132 of the light-emitting module 130 can be triggered to emit light. In this way, with the aforementioned configuration of the electronic device 100, the user can achieve the same effect of pressing force and hand feeling.

In some embodiments, the width of the switch 150 is substantially smaller than the width of the gap G, so that when the button 120 is pressed, the switch 150 can advance a certain distance to contact the supporting structure 170, thereby triggering the light source 132 of the light emitting module 130 to emit light.

In some embodiments, as shown in FIG. 3, the vertical projection of the switch 150 on the housing 110 overlaps the vertical projection of the button 120 on the housing 110. For example, the vertical projection of the switch 150 on the housing 110 is located in the middle of the vertical projection of the button 120 on the housing 110.

In some embodiments, as shown in FIG. 3, the housing 110 has a first part 116 and a second part 118, and the second part 118 is connected to the first part 116. The first part 116 of the housing 110 contacts the button 120, and the second part 118 of the housing 110 contacts the support structure 170. In other words, the button 120 and the supporting structure 170 respectively contact two opposite sides of the housing 110.

In some embodiments, the button 120 protrudes from the opening 112 of the housing 110. In detail, a part of the button 120 protrudes from the surface of the housing 110 for the user to press, and another part of the button 120 is located in the opening 112. In some embodiments, the housing 110 completely covers the supporting structure 170, and a part of the button 120 is exposed outside the housing 110.

In some embodiments, the button 120 is made of plastic material. When the user presses the button 120, the problem caused by excessive deformation can be avoided. In some embodiments, the button 120 is integrally formed and has the advantages of simple and robust structure. In some embodiments, the button 120 is made of a transparent material, which helps the light to be concentrated to the outside of the button 120, which is convenient for the user to operate, thereby enhancing the user's operating experience.

In some embodiments, the circuit board 140 may be a printed circuit board (PCB). The supporting structure 170 is made of a rigid material, so that the supporting structure 170 will not be deformed when in contact with the switch 150.

In some embodiments, the length of the circuit board 140 is greater than the length of the support structure 170. In some embodiments, the length of the support structure 170 is greater than the length of the key 120.

To sum up, the present disclosure provides an electronic device, which includes a housing, a button, a light-emitting module, a circuit board, and a switch. Since the switch and the light guide plate are respectively located on two opposite sides of the circuit board, the user's operating feel can be improved, and the light can be concentrated to the middle position of the button, thereby avoiding the problem of light leakage.
