Description

[0002] An optical key is a key that uses optical sensing technology to detect actions. An optical key detects pressing and releasing actions by replacing traditional mechanical contacts with optical components. When a key is pressed, it blocks or changes the propagation path of light. The photosensitive receiving element under the key receives light signals of different intensities or the absence of light, thereby converting this optical change into an electrical signal and transmitting it to the control chip of the device to identify the operation of the key. Nowadays, many computer input devices use optical keys, such as optical key mice.
[0003] Since there is no wear problem of mechanical contacts, the life of optical keys is usually much longer than that of traditional mechanical micro-switch keys, which can greatly reduce double-clicks, failures and other faults caused by key wear. Optical keys also have the advantages of fast response speed, high stability, and consistent key feel. However, today's optical keys are usually equipped with a single light source. For example, if an optical key mouse is equipped with multiple optical keys, it is necessary to match multiple light-emitting parts for each of the multiple optical keys.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.
[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0040] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0041] The present invention provides Figure 1 , Figure 2 and Figure 3 As shown, a light guide body 1 is used to disperse and conduct the light source of the light emitting element 31 to a plurality of photosensitive receiving elements 33 arranged on a computer input device; the main structure of the present invention includes: a light guide body 1, the light guide body 1 is a transparent material structure that can guide light, and a light source input end 11 and a plurality of light source output ends 12 are arranged on the light guide body 1. Among them, the light source input end 11 is close to the light emitting element 31 (such as an LED light emitting element 31) of the computer input device, and the light emitting element 31 irradiates toward the light source input end 11. The light source output end 12 is toward the mouse optical IC 32 or photosensitive receiving element 33 of the computer input device. The light guide body 1 is used to disperse and conduct the light source of the light source input end 11 to a plurality of light source output ends 12, and irradiate onto the mouse optical IC 32 or photosensitive receiving element 33 near the light source output end 12. Among them, in order to avoid the light from being refracted and lost, the light guide body 1, the light source input end 11 and the light source output end 12 are formed in one piece.
[0042] It should be noted that currently, a single light source is usually configured for the optical key 231. For example, if a mouse with an optical key 231 is equipped with multiple optical keys 231, it is necessary to respectively match multiple light-emitting elements 31 with the multiple optical keys 231. This structural design will inevitably increase the power consumption of the mouse and increase the production cost of the mouse.
[0043] This solution disperses the light source of the single light emitting element 31 to a plurality of light source output ends 12 through the light guide body 1, providing light source to a plurality of light sensitive receiving elements 33 with different functional definitions. Only one single light source is needed to enable the entire device to realize the light control function, effectively reducing the energy consumption and production cost of the device.
[0044] Further, such as Figure 1 , Figure 2 and Figure 3 As shown, a plurality of light guide extensions 13 are provided on the light guide body 1, and a light source output end 12 is provided on the light guide extension 13 at one end away from the light guide body 1, and the light guide body 1, the light guide extension 13, the light source input end 11 and the light source output end 12 are integrally formed. The light guide extension 13 can be a plastic columnar structure, or a structure with a fixed structure.
[0045] In some embodiments, the light guide extension 13 is a light guide fiber. One end of the light guide fiber is connected to the light guide body 1, and the other end is toward the mouse optical IC 32 or the photosensitive receiving element 33 of the computer input device. The light guide fiber can be adjusted and bent according to the internal structure of the computer input device to achieve end-to-end light transmission, which is convenient for production and assembly.
[0046] Further, such as Figure 2 and Figure 3As shown, the light source input end 11 is provided with a concave arc notch 111, which is used to accommodate the light emitting element 31. The concave arc notch 111 can better surround the light emitting element 31, so that the light emitted by the light emitting element 31 can irradiate the light guide body 1 as much as possible, avoiding light source scattering and affecting the utilization rate of light.
[0047] Furthermore, a light-blocking layer is provided on the side wall of at least one of the light guide body 1 and the light guide extension 13, and the light-blocking layer is used to prevent the scattering of the light source. It is understandable that the light guide body 1 is a transparent material structure, and the side of the light guide body 1 is prone to scattering of the light source, which can easily lead to insufficient light at the light source output end 12. This will in turn affect the effective utilization rate of the light source output by the light-emitting component 31. Therefore, a light-blocking layer is provided on the side wall of at least one of the light guide body 1 and the light guide extension 13, and the light source originally scattered from the side wall of the light guide body 1 and the light guide extension 13 is reflected back through the light-blocking layer. In this way, the effective utilization rate of the light source output by the light-emitting component 31 is improved.
[0048] Furthermore, the light blocking layer is a metal coating. For example, aluminum coating, chrome coating and silver coating all have good reflective properties. They can effectively reflect the light of the light emitting element 31, prevent the light source from scattering from the side walls of the light guide body 1 and the light guide extension 13, and effectively improve the utilization rate of the light source.
[0049] Furthermore, the light guide body 1 is a plexiglass structure. It should be noted that the plexiglass is called polymethyl methacrylate (PMMA). PMMA has excellent optical transparency, with a light transmittance of up to about 92%, and a refractive index of about 1.49, which enables light to propagate efficiently therein. And it can be made into various complex shapes through processes such as injection molding and extrusion, which is conducive to the design and manufacture of the light guide body 1. It is more convenient to design the light guide body 1 into different shapes according to the requirements of the optical key 231 of the device.
[0050] And the density of plexiglass is relatively low, about 1.19g / cm 3 , light texture, easy to install and use. Organic glass has good weather resistance, can maintain good performance under different ambient temperature and humidity conditions, and is not easy to turn yellow and brittle. For example, the light guide plate used in outdoor advertising light boxes, PMMA material can withstand long-term sun and rain without affecting the light guide effect.
[0051] like Figure 4 and Figure 5As shown, the second aspect of the present application provides a single-light source pure digital signal mouse, which is a common computer external input device used to help users control computers. It includes: a mouse housing 2, a circuit board 3, and a light guide body 1 as described in any one of the first aspects, the mouse housing 2 is provided with a plurality of buttons 231; the circuit board 3 is arranged in the mouse housing 2, and the circuit board 3 is provided with a light emitting element 31, a mouse optical IC 32, and a plurality of photosensitive receiving elements 33; the light guide body 1 is arranged in the mouse housing 2, the light source input end 11 on the light guide body 1 is arranged correspondingly to the light emitting element 31, the mouse optical IC 32 is arranged correspondingly to one of the plurality of light source output ends 12 on the light guide body 1, and the plurality of photosensitive receiving elements 33 are respectively arranged correspondingly to the light source output ends 12, and the button 231 is used to conduct or cut off the channel between the photosensitive receiving element 33 and the light source output end 12.
[0052] It should be noted that the optical key 231 detects the pressing and releasing actions by replacing the traditional mechanical contacts with optical components. When the key 231 is pressed, the propagation path of the light will be blocked or changed, and the light receiving element 33 located under the key 231 will receive light signals of different intensities or the presence or absence of light, thereby converting this optical change into an electrical signal and transmitting it to the control chip of the device to identify the operation of the key 231.
[0053] Further, such as Figure 4 and Figure 5 As shown, the mouse housing 2 includes: a lower housing 21, a middle housing 22 and an upper housing 23. A through hole 211 is provided at the bottom of the lower housing 21. An optical lens 212 is provided at a position corresponding to the through hole 211 on the lower housing 21. A light source input terminal 11 is provided on one side of the optical lens 212. The mouse optical IC 32 is provided corresponding to the optical lens 212. The middle housing 22 is provided on the lower housing 21. The middle housing 22 and the lower housing 21 are connected to form a receiving cavity. The circuit board 3 is provided in the receiving cavity. The upper housing 23 is provided on the middle housing 22. At least one button 231 is provided on the upper housing 23. A light shielding sheet 2311 is provided on the button 231. The light shielding sheet 2311 extends to the passage between the photosensitive receiving element 33 and the light source output terminal 12. The light shielding sheet 2311 is used to block or change the propagation path of the light output from the light source output terminal 12. The photosensitive receiving element 33 located under the button 231 will receive light signals of different intensities or presence or absence, thereby converting this optical change into an electrical signal and transmitting it to the control chip of the device to identify the operation of the button 231.
[0054] Further, such as Figure 5As shown, a first magnetic member 41 is disposed on the button 231, and a second magnetic member 42 is disposed on the middle shell at a position corresponding to the first magnetic member 41. The first magnetic member 41 and the second magnetic member 42 repel or attract each other to form a reset structure 4, and the reset structure 4 is used to reset the button 231. The reset structure 4 formed by the first magnetic member 41 and the second magnetic member 42 can improve the damping touch when the button 231 is active, which can effectively improve the user's touch experience.
[0055] A third aspect of the present application provides a light control method for a single-light-source pure digital signal mouse according to any one of the second aspects, the light control method comprising the following steps:
[0056] Step 1: receiving light emitted by the light emitting element 31 through the light source input end 11 of the light guide body 1, wherein the light source input end 11 and a plurality of light source output ends 12 are provided on the light guide body 1;

[0059] Step 4: Obtain the photosensitivity signal of the photosensitivity receiving element 33 and the photosensitivity signal of the mouse optical IC 32 corresponding to the optical lens 212 .
[0060] In summary, the present application provides a light guide body 1, a single light source pure digital signal mouse and a light control method. The present solution disperses the light source of a single light emitting element 31 to a plurality of light source output ends 12 through the light guide body 1, and provides light to a plurality of light sensitive receiving elements 33 with different functional definitions. Only a single light source is needed to enable the overall device to realize the light control function, effectively reducing the energy consumption and production cost of the device.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
