Detailed Description
In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.
Referring to fig. 1, fig. 2, and fig. 3, fig. 1 is a top view of an input device 10 according to an embodiment of the present invention, fig. 2 is an exploded view of a roller device 20 of fig. 1, and fig. 3 is an axial cross-sectional view of the roller device 20 of fig. 2 after assembly, wherein a lower housing 12 and an upper housing 14 are only schematically shown in fig. 3 by dashed lines, and related descriptions of the input device housing design are common in the prior art and are not repeated herein. The input device 10 can be applied to a portable electronic device (such as a notebook computer or a foldable keyboard device) having a folding mechanism composed of an upper case and a lower case, for a user to operate and execute a function desired by the user, as shown in fig. 1, fig. 2, and fig. 3, the input device 10 includes a lower case 12, an upper case 14, a main circuit board 16, a pressing input device 18, and a roller device 20. The upper housing 14 is connected to the lower housing 12 and has a roller slot 15 for receiving the roller device 20. The main circuit board 16 is disposed in the lower casing 12, the press input device 18, which is preferably a keyboard key combination, is disposed on the upper casing 14 for pressing operation by a user, and the press input device 18 is electrically connected to the main circuit board 16 for outputting a corresponding press input signal to the main circuit board 16 according to the key pressing operation by the user.
As for the design of the roller device 20, as shown in fig. 1, 2 and 3, the roller device 20 includes a hollow roller member 22, an encoder 24, a led circuit board 26, and leds 28 and 29 (the number (single or multiple) and arrangement of the leds may vary according to the actual application of the input device 10, and is not limited to fig. 2 and 3). The hollow roller member 22 is rotatably suspended in the roller slot 15 and partially protrudes from the roller slot 15, so that a user can perform a forward and backward rotation operation (e.g., an up and down movement of a longitudinal roller bar of a control window operation interface) by pushing the hollow roller member 22 with a finger. The encoder 24 is electrically connected to the main circuit board 16 and located at one side of the hollow roller member 22, and outputs a rolling input signal to the main circuit board 16 according to the rolling of the hollow roller member 22 to perform a function desired by a user. The led circuit board 26 is electrically connected to the encoder 24 and extends into the hollow roller member 22, and the leds 28 and 29 are disposed on the led circuit board 26 for emitting light to the hollow roller member 22.
In more detail, in this embodiment, the first end P1 of the hollow roller member 22 close to the encoder 24 has a first rotating shaft 30 and the second end P2 far from the encoder 24 has a second rotating shaft 32, so that the hollow roller member 22 can be rotatably suspended on the upper casing 14 via the first rotating shaft 30 and the second rotating shaft 32, and the first rotating shaft 30 can be formed with a shaft through hole 34 to allow the led circuit board 26 to extend into the hollow roller member 22 through the shaft through hole 34. In practical applications, in order to improve the assembly convenience of inserting the led circuit board 26 into the hollow roller member 22 through the axial through hole 34, the axial slot 36 may be transversely formed on the first rotating shaft 30 (as shown in fig. 2), so that the led circuit board 26 can be smoothly inserted into the hollow roller member 22 through the axial slot 36, further, the slot width of the axial slot 36 may be preferably larger than the diameter of the first rotating shaft 30, the axial slot 36 has two slot ends 42 extending outward relative to the first rotating shaft 30, the two slot ends 42 are located at the first end P1 of the hollow roller member 22, thereby suitably enlarging the board area of the led circuit board 26 that can be inserted into the hollow roller member 22, and facilitating the flexible configuration of the number of leds (for example, a plurality of leds may be configured to provide sufficient light to the hollow roller member 22, thereby enhancing the light emission luminance of the hollow roller member 22).
It should be noted that, in order to further prevent light leakage, as shown in fig. 2, the roller device 20 may further include a light shielding film 38 (schematically shown by a dotted line in fig. 2), the light shielding film 38 may be circumferentially attached to an outer periphery 40 of the first rotating shaft 30 and respectively covers two slot ends 42 of the axial slot 36 extending outward relative to the first rotating shaft 30, so as to shield the light of the light emitting diodes 28, 29 from being emitted from the axial slot 36, and the light shielding film 38 has a light leakage preventing effect.
Through the above design, after completing the assembly of the led circuit board 26 shown in fig. 2 through the axial through hole 34 and the axial slot hole 36 to extend into the hollow roller member 22, as can be seen from fig. 3, compared to the prior art adopting the design of emitting light from bottom to top, the light emitted by the leds 28 and 29 can directly emit from the inside of the hollow roller member 22 to the surface of the roller structure of the hollow roller member 22 to improve the light utilization efficiency, thereby providing sufficient light to the hollow roller member 22, and thus, the present invention can effectively solve the problems of low light utilization efficiency and poor light emitting effect caused by the prior art of disposing the light emitting unit under the roller. In addition to the above design for providing sufficient light to illuminate the entire hollow roller member 22, in practical applications, the roller device 20 may be designed such that only two ends of the hollow roller member 22 are made of transparent material, so that the light emitted from the light emitting diodes 28, 29 is only transmitted from two ends of the hollow roller member 22 to generate the illumination effect at two ends of the roller. In addition, as shown in fig. 3, the roller device 20 may be designed to have a partially transparent pattern 44 (such as, but not limited to, a neon pattern) formed around the outer periphery 46 of the hollow roller member 22, so that the light emitted from the leds 28, 29 can be emitted from the transparent region 48 of the partially transparent pattern 44 to generate a local light effect.
It should be noted that the above-mentioned two-end light-emitting design is not limited to the above-mentioned embodiments, and it can also adopt a light-guiding design, for example, please refer to fig. 4, which is an axial cross-sectional schematic view of a roller device 100 according to another embodiment of the present invention. As shown in fig. 4, the roller device 100 includes a first annular slant light guide structure 102, a second annular slant light guide structure 104, a hollow roller member 22, an encoder 24, and a led circuit board 26, and light emitting diodes 28 and 29, wherein the first annular inclined light guiding structure 102 is formed in the hollow roller 22 at a position corresponding to the light emitting diode 28 and inclined toward the first end P1 of the hollow roller 22, the second annular inclined light guiding structure 104 is formed in the hollow roller 22 at a position corresponding to the light emitting diode 29 and inclined toward the second end P2 of the hollow roller 22, so that the first annular inclined light guiding structure 102 can guide the light emitted by the light emitting diode 28 to enter the first end P1 of the hollow roller 22 and the second annular inclined light guiding structure 104 can guide the light emitted by the light emitting diode 29 to enter the second end P2 of the hollow roller 22, thereby generating the light emitting effect at both ends of the roller. It should be noted that the second annular inclined light guiding structure 104 is an element that can be omitted to simplify the structural design of the roller device provided by the present invention.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
