[0002] Existing capacitive sensing modules installed in laptop computers control the operation of related components of the laptop computer by sensing changes in capacitance around the casing.

[0057] In the following description, if a specific drawing is indicated or shown in a particular drawing, it is only for emphasis in the following description, and most of the content mentioned and related appears in that particular drawing, but it does not limit the following description to refer only to that particular drawing.

[0058] Please refer to the following: Figures 1 to 5 The electronic device 100 of the present invention includes a housing 1, a sensing module 2, a keyboard module 3, and a display module 4. The electronic device 100 can be a notebook computer. The sensing module 2 and the keyboard module 3 are disposed within the housing 1. The display module 4 is movably connected to the housing 1 and may include a display screen and the housing. The display screen may be, for example, a conventional display screen or a touch screen. In different embodiments, the electronic device 100 may also be a tablet computer, etc., and this is not limited thereto. It should be noted that the housing 1 also contains related electronic components for enabling the electronic device 100 to operate normally, such as a motherboard, memory, and a central processing unit (CPU), which can vary according to requirements and are not limited here.

[0059] like Figure 2 and Figure 3 As shown, the housing 1 may include a main body 11 and a cover plate 12. The cover plate 12 is detachably fixed to the main body 11. The sensing module 2 of the present invention is fixedly disposed on the main body 11, and a portion of the sensing module 2 is exposed outside the housing 1. The sensing module 2 is used to sense changes in capacitance of the surrounding environment and emit a corresponding light beam accordingly. For example, when a user's finger approaches the vicinity of the sensing module 2, the sensing module 2 will sense a change in capacitance of the surrounding environment, and the user can then see the sensing module 2 exposed outside the housing 1 illuminate.

[0060] Please refer to the following: Figures 4 to 9 The sensing module 2 of the present invention includes: a substrate 21, five light-emitting units 22, a light guide component 23, two sensing circuit structures 24, and a sensing processor 25. The number of light-emitting units 22 included in the sensing module 2 can be increased or decreased as needed, and is not limited to the number shown in the figures. In different embodiments, the sensing module 2 may also include only a single sensing circuit structure 24.

[0061] Five light-emitting units 22 are spaced apart on the substrate 21. Each light-emitting unit 22 may be, for example, a light-emitting diode capable of emitting at least one color. The substrate 21 is electrically connected to the motherboard (not shown) of the electronic device 100, and the battery of the electronic device 100 can provide power to each light-emitting unit 22 through the motherboard (not shown) and the substrate 21. In practical applications, the substrate 21 may be electrically connected to the motherboard (not shown) of the electronic device 100 through an electrical connection component (such as a flexible circuit board, ribbon cable, etc.), but the connection method between the substrate 21 and the motherboard (not shown) is not limited thereto. The substrate 21 may include a flexible circuit board, a rigid circuit board, or both flexible and rigid circuit boards, and there is no limitation herein.

[0062] The light guide assembly 23 includes five light guide structures 231, a light emitting structure 232, and a barrier structure 233. The five light guide structures 231 are spaced apart from each other, and each light guide structure 231 has a light incident surface 2311. Each light incident surface 2311 faces a light emitting surface 221 of one of the light-emitting units 22. The light emitting structure 232 is connected to the five light guide structures 231 and includes a light emitting surface 2321, which is exposed outside the housing 1 (e.g., ...). Figure 2 As shown in the figure, in practical applications, the light-emitting surface 2321 can be approximately flush with the outer surface of the housing 1, but is not limited thereto. The light-emitting surface 2321 can also protrude from the outer surface of the housing 1, or the light-emitting surface 2321 can be slightly concave relative to the outer surface of the housing 1.

[0063] The light beams emitted from the light-emitting surfaces 221 of each light-emitting unit 22 can enter the light-guiding structure 231 through the light-incident surfaces 2311 of the adjacent light-guiding structure 231, and be guided by the light-guiding structure 231 to concentrate into the light-emitting structure 232. Finally, they are emitted outward from the light-emitting surfaces 2321 of the light-emitting structure 232. In other words, each light-guiding structure 231 is mainly used to ensure that most of the light beams emitted by the light-emitting unit 22 can be emitted from the light-emitting surfaces 2321 of the light-emitting structure 232. The specific shape of the light-guiding structure 231 is not limited to that shown in the figure. The number of light-guiding structures 231 included in the light-guiding assembly 23 is not limited to that shown in the figure, and the number of light-guiding structures 231 included in the light-guiding assembly 23 corresponds to the number of light-emitting units 22. In practical applications, the light-guiding structures 231 and the light-emitting structures 232 can be made of transparent or translucent materials, for example, but are not limited thereto.

[0064] The barrier structure 233 may include six barrier walls 2331 and a connecting wall 2332. Each light-emitting unit 22 has a barrier wall 2331 on both sides, and the connecting wall 2332 is connected to the six barrier walls 2331. Each light-guiding structure 231 has a barrier wall 2331 on both sides. The light-guiding structures 231, two adjacent barrier walls 2331, and a part of the adjacent connecting wall 2332 will together form an accommodating space S, and each light-emitting unit 22 is correspondingly arranged in an accommodating space S.

[0065] Each baffle 2331 and connecting wall 2332 is used to ensure that most of the light beam emitted by the adjacent light-emitting unit 22 can enter the light guide structure 231 adjacent to the light-emitting unit 22. In a preferred embodiment, each baffle 2331 can be made of a material capable of reflecting the light beam emitted by the light-emitting unit 22, while the portion of the light beam emitted by the light-emitting unit 22 that does not enter the adjacent light guide structure 231 can re-enter the light guide structure 231 through reflection by the baffle 2331 or connecting wall 2332. In different embodiments, each baffle 2331 can also be made of a material capable of absorbing the light beam emitted by the light-emitting unit 22.

[0066] As described above, through the design of the light guide structure 231, the light emission structure 232, and the barrier structure 233, most of the light beams emitted by each light-emitting unit 22 will be emitted outward from the light emission surface 2321 of the light emission structure 232. The user can clearly see the number of light-emitting units 22 currently illuminated by the sensing module 2 from the light emission surface 2321 of the light emission structure 232. It should be noted that the number of barriers 2331 included in the barrier structure 233, and the position of each barrier 2331 relative to the light guide structure 231 and the light-emitting unit 22, are not limited to those shown in the figure.

[0067] like Figures 6 to 8As shown, in practical applications, the barrier structure 233 may also include two fixing parts 2333. These two fixing parts 2333 may be located at both ends of the barrier structure 233, and the light guide assembly 23 may be fixed to the substrate 21 via the two fixing parts 2333. For example, each fixing part 2333 may be a cylindrical structure, and the substrate 21 may have two corresponding through holes 211, with each fixing part 2333 fixed in one of the through holes 211. The fixing parts 2333 and the through holes 211 may be fixed to each other in a tight fit, for example. The number of fixing parts 2333 included in the barrier structure 233 and the number of through holes 211 included in the substrate 21 are not limited to those shown in the figures, and the shape and size of each fixing part 2333 and each through hole 211 are also not limited to those shown in the figures. Of course, the way the light guide component 23 is fixed to the substrate 21 is not limited to the above description. In different embodiments, the light guide component 23 may also be fixed to the substrate 21 by means of adhesive or the like. Alternatively, the light guide component 23 may be fixed to the substrate 21 by both the fixing part 2333 and the adhesive.

[0068] A portion of each sensing circuit structure 24 is disposed on one side 23A of the light guide assembly 23, which is adjacent to the light emitting surface 2321. Each sensing circuit structure 24 has a fixed end 24A and a free end 24B at its two ends. The fixed end 24A of each sensing circuit structure 24 is used for electrical connection with the substrate 21, and the free ends 24B of each sensing circuit structure 24 are disposed at intervals on the side 23A of the light guide assembly 23.

[0069] Each sensing circuit structure 24 may also include a sensing section 24C located on the side 23A. The fixed end 24A of each sensing circuit structure 24 may be used to electrically connect to an electrical connection structure 212 on the substrate 21, for example by soldering. Each sensing circuit structure 24 is electrically connected to the sensing processor 25 or an external controller (e.g., the central processing unit of the electronic device 100) through the electrical connection structure 212.

[0070] In practical applications, the five light guiding structures 231, light emitting structures 232, and barrier structures 233 included in the light guide component 23 can be integrally manufactured using dual-material injection molding technology, and the two sensing circuit structures 24 can be formed on the light guide component 23 using laser direct forming (LDS) technology.

[0071] like Figure 8 and Figure 9As shown, in a preferred embodiment, the light guide assembly 23 may further include an auxiliary side surface 23C, which is adjacent to the side surface 23A. The normal vector of the auxiliary side surface 23C is not parallel to the normal vector of the side surface 23A, and a portion of the sensing section 24C of the sensing circuit structure 24 is disposed on the auxiliary side surface 23C. For example, if the side surface 23A of the light guide assembly 23 is located in the XY plane of the coordinate system shown in the figure, then the auxiliary side surface 23C is not located in the XY plane, and the auxiliary side surface 23C may face the light emitting surface 2321. By designing a portion of the sensing circuit structure 24 to be disposed on the auxiliary side surface 23C, the sensing sensitivity of the sensing section 24C of each sensing circuit structure 24 can be improved.

[0072] A sensing processor 25 is disposed on the substrate 21. The sensing processor 25 can cooperate with two sensing circuit structures 24 to sense the capacitance changes around each sensing circuit structure 24 and generate a corresponding sensing signal. The sensing processor 25 or an external controller (such as the central processing unit of the electronic device 100) can control at least one light-emitting unit 22 according to the sensing signal, thereby causing at least one light-emitting unit 22 to emit light, turn off light, emit a light beam of a specific color, increase brightness, decrease brightness, etc.

[0073] In one specific embodiment, when a user's finger approaches the light-emitting surface 2321 of the light-emitting structure 232 of the sensing module 2, and at least one sensing circuit structure 24 and sensing processor 25 cooperate with each other to sense a change in capacitance around the sensing circuit structure 24, the sensing processor 25 will generate a sensing signal accordingly. After receiving the sensing signal, the sensing processor 25 or the central processing unit (i.e., the external controller) of the electronic device 100 can control at least one light-emitting unit 22 to emit light based on the current battery level of the electronic device 100. In this way, the user can know the current battery level of the electronic device 100 by observing the number of currently emitting light-emitting units 22. For example, if the user sees five light-emitting units 22 lit up, it means that the battery level is 80-100%. If four light-emitting units 22 are lit up, it means that the battery level is 60-80%, and so on. If only one light-emitting unit 22 is lit up, it means that the battery level is less than 20%. In one embodiment, when the battery power is less than 20%, the sensing processor 25 may control the single light-emitting unit 22 to light up, or it may control the light-emitting unit 22 to emit light beams of different colors (e.g., red) to remind the user that the current battery power is low and needs to be charged.

[0074] Of course, after receiving the sensing signal, the sensing processor 25 or the external controller is not limited to controlling at least one light-emitting unit 22 of the sensing module 2 to light up based on the current power of the electronic device 100. In practical applications, the sensing processor 25 or the external controller can control different numbers of light-emitting units 22 to light up according to the actual needs of the electronic device 100 based on the different states of the electronic device 100 (such as wireless signal strength).

[0075] It should be noted that in the embodiment where the sensing module 2 includes two sensing circuit structures 24, the sensing processor 25 can cooperate with the two sensing circuit structures 24 respectively to sense whether a change in capacitance occurs around each sensing circuit structure 24. For example, the sensing processor 25 can control at least one light-emitting unit 22 to light up only when both sensing circuit structures 24 sense a change in capacitance around them. When only one sensing circuit structure 24 senses a change in capacitance around it, the sensing processor 25 will not control either light-emitting unit 22 to light up. In this way, the situation of misjudgment by the sensing module 2 can be effectively avoided.

[0076] In an embodiment where the sensing module 2 includes two sensing circuit structures 24, the sensing processor 25 can also cooperate with the two sensing circuit structures 24 to determine whether the user is sliding from left to right or from right to left on the light-emitting surface 2321 (or in the air adjacent to the light-emitting surface 2321). The sensing processor 25 can control at least one light-emitting unit 22 to emit light according to different states of the electronic device 100. For example, if the sensing processor 25 determines that the user is sliding from the right side of the light-emitting surface 2321 to the left side, the sensing processor 25 can control the corresponding number of light-emitting units 22 to light up according to the battery power of the electronic device 100. Conversely, if the sensing processor 25 determines that the user is sliding from the left side of the light-emitting surface 2321 (or in the air adjacent to the light-emitting surface 2321) to the right side, the sensing processor 25 can control the corresponding number of light-emitting units 22 to light up according to the wireless signal strength of the electronic device 100.

[0077] In an embodiment where the sensing module 2 includes two sensing circuit structures 24, the sensing processor 25 may also control at least one light-emitting unit 22 to operate only when both sensing circuit structures 24 sense the capacitance change around them and it exceeds a predetermined threshold based on the two sensing signals.

[0078] Please refer to the following: Figure 1 and Figure 5In one specific embodiment, the substrate 21 can be a flexible circuit board. Five light-emitting units 22 are disposed at one end of the substrate 21, while the other end of the substrate 21 is used to connect to an external controller (e.g., the central processing unit of the electronic device 100). The electronic device 100 may also include a transient voltage suppressor (TVS) and at least one capacitor C. The sensing processor 25, the transient voltage suppressor TVS, and the capacitor C are disposed on the flexible circuit board 21B. The sensing processor 25 is electrically connected to the sensing circuit structure 24 through a path on the flexible circuit board (e.g., a conductive metal line located within the flexible circuit board 21B). One end of the transient voltage suppressor TVS is connected to the path, and one end of the capacitor C is connected to the path. The other end of the transient voltage suppressor TVS is grounded, and the other end of the capacitor C is grounded. By providing the transient voltage suppressor TVS and the capacitor C, the influence of static electricity on the sensing circuit structure 24 can be effectively avoided.

[0079] In practical applications, the number of transient voltage suppressors (TVS) and capacitors C included in the sensing module 2 can correspond to the number of sensing circuit structures 24, but is not limited thereto. The placement of the transient voltage suppressors (TVS) and capacitors C is also not limited to what is shown in the figure. In practical applications, the transient voltage suppressors (TVS) and capacitors C can be placed adjacent to the sensing circuit structure 24, which will improve the electrostatic discharge (ESD) protection effect.

[0080] It should be particularly emphasized that the accompanying drawings of this embodiment are based on the example of the sensing module 2 containing two sensing circuit structures 24. However, the number of sensing circuit structures 24 contained in the sensing module 2 is not limited to two. In different embodiments, the sensing module 2 may also contain only a single sensing circuit structure 24.

[0081] Please refer to the following: Figures 10 to 16 The diagrams shown below illustrate different embodiments of the sensing module of the present invention. The sensing module 5 in this embodiment includes a substrate 51, five light-emitting units 52, a light guide assembly 53, two sensing circuit structures 54, and a sensing processor 55. The light-emitting units 52 and sensing processor 55 described in this embodiment are the same as those in the aforementioned embodiments, and will not be repeated hereafter.

[0082] The substrate 51 may include a rigid circuit board 51A and a flexible circuit board 51B. Multiple light-emitting units 52 are disposed on the rigid circuit board 51A. The flexible circuit board 51B is connected to the rigid circuit board 51A. The end of the flexible circuit board 51B opposite to the end connected to the rigid circuit board 51A is used to connect to the electronic device 100 (e.g., ...). Figure 1The motherboard shown is a board. Of course, in different embodiments, the substrate 51 may only contain a rigid circuit board 51A, and the substrate 51 is electrically connected to the motherboard of the electronic device 100 through connecting wires, contacts, etc.

[0083] The light guide assembly 53 includes a light guide structure 531, a light emitting structure 532, two fixing structures 533, and two auxiliary fixing structures 534. In practical applications, the light guide structure 531, the light emitting structure 532, the two fixing structures 533, and the two auxiliary fixing structures 534 can be integrally formed. The two ends of the light guide structure 531 are connected to the two fixing structures 533, which abut against the side of the substrate 51 where five light-emitting units 52 are provided. Each fixing structure 533 may, for example, include a fixing post 5331, which engages with a fixing hole 511 in the substrate 51.

[0084] like Figures 13 to 15 As shown, the light guide structure 531 has a light-incident surface 5311 facing a light-emitting surface 521 of each light-emitting unit 52. The side of the light guide structure 531 opposite to the light-incident surface 5311 is connected to the light-emitting structure 532. The light beams emitted by each light-emitting unit 52 from its light-emitting surface 521 enter the light guide structure 531 through the light-incident surface 5311, are guided by the light guide structure 531, and then emitted outwards from the light-emitting surface 5321 of the light-emitting structure 532. The shape of the light guide structure 531 is not limited to that shown in the figure. In practical applications, the shape of the light guide structure 531 can be changed to make the light beams entering the light guide structure 531 more concentrated and emitted outwards from the light-emitting surface 5321 of the light-emitting structure 532.

[0085] In the accompanying drawings of this embodiment, the light-incident surface 5311 of the light guide structure 531 is shown as having a gap between it and the light-emitting surface 521 of each light-emitting unit 52. However, in actual applications, this is not the limitation. In different embodiments, there may be almost no gap between the light-incident surface 5311 and each light-emitting surface 521, or the light-incident surface 5311 may abut against each light-emitting surface 521.

[0086] In the accompanying drawings of this embodiment, the light guide structure 531 is shown as having only a single planar light incident surface 5311. However, the number and shape of the light incident surfaces 5311 included in the light guide structure 531 are not limited to this. In different embodiments, the light guide structure 531 may also include five light incident surfaces 5311, and each light incident surface 5311 is an arc surface, and each light incident surface 5311 is a light emitting surface 521 facing one of the light emitting units 52.

[0087] like Figures 11 to 15As shown, the two auxiliary fixing structures 534 may each include a through hole 5341, and each through hole 5341 can be used to provide housing 1 (e.g. Figure 1 Two limiting structures (not shown, for example, cylindrical structures) are inserted, and the two auxiliary fixing structures 534 and the two limiting structures can together restrict the light guide assembly 53 relative to the housing 1 (e.g., Figure 1 The activity range is shown in the diagram. Each sensing circuit structure 54 has a fixed end 54A and a free end 54B at its two ends. A portion of each sensing circuit structure 54 is disposed on one side 53A of the light guide assembly 53, adjacent to the light-emitting surface 5321, and a sensing section 54C of each sensing circuit structure 54 is located on the side 53A. The free ends 54B of each sensing circuit structure 54 are spaced apart from the side 53A. The fixed ends 54A of each sensing circuit structure 54 may be disposed on the other side 53B of the light guide assembly 53, adjacent to the side 53A. When the light guide assembly 53 is fixed to the substrate 51, the fixed ends 54A of each sensing circuit structure 54 can be electrically connected to an electrical connection structure 5111 of the substrate 51.

[0088] In a preferred embodiment, the light guide assembly 53 may further include a protruding structure 535, which is integrally formed with the light guide structure 531. The protruding structure 535 may be disposed on the side surface 53A, and may have an auxiliary side surface 5351 adjacent to the side surface 53A. The normal vector of the auxiliary side surface 5351 is not parallel to the normal vector of the side surface 53A, and a portion of the sensing section 54C of each sensing circuit structure 54 is disposed on the auxiliary side surface 5351, which is generally oriented towards the light emitting surface 5321. Similar to the previous embodiment, by disposing a portion of the sensing section 54C of each sensing circuit structure 54 on the auxiliary side surface 5351, the sensing sensitivity of each sensing circuit structure 54 can be further improved.

[0089] Please refer to the following: Figure 11 and Figure 12As shown, in practical applications, the sensing module 5 may also include an insulating shielding member 56 disposed on the side 53A of the light guide assembly 53. The insulating shielding member 56 is used to shield at least a portion of the sensing sections 54C of each sensing circuit structure 54 to prevent the sensing sections 54C from being directly exposed. Of course, the function of the sensing processor 55 in cooperating with each sensing circuit structure 54 to sense changes in the surrounding capacitance of each sensing circuit structure 54 is not affected by the insulating shielding member 56, which is only used to protect the sensing sections 54C. In one specific application, the insulating shielding member 56 may also be an adhesive, which can be used to assist in fixing the light guide assembly 53 to the substrate 51.

[0090] It should be particularly emphasized that the accompanying drawings of this embodiment are based on the example of the sensing module 5 containing two sensing circuit structures 54. However, the number of sensing circuit structures 54 contained in the sensing module 5 is not limited to two. In different embodiments, the sensing module 5 may also contain only a single sensing circuit structure 54.

[0091] In summary, the electronic device and sensing module of the present invention, by arranging the sensing sections of each sensing circuit structure on the side of the light guide structure, and with the side adjacent to the light emitting surface of the light emitting structure, allows the sensing circuit structure to be closer to the location touched or approached by the user (i.e., the light emitting surface), thereby enabling the sensing circuit structure to better sense changes in capacitance around it. Furthermore, by designing that no other electronic components or conductors are disposed between each sensing circuit structure and the light emitting surface, the electronic device and sensing module of the present invention can significantly reduce the possibility of misjudgments by the sensing circuit structure.

[0092] It is worth mentioning that the sensing module of the present invention can also be manufactured, implemented and sold independently, and the sensing module is not limited to being manufactured, implemented and sold only together with the above-mentioned electronic device.

[0093] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made based on the description and drawings of the present invention are included within the protection scope of the present invention.
