Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic equipment, and particularly relates to a light guide member body and a single-light-source pure digital signal mouse. BACKGROUND

[0002] A photosensitive key is a key that detects actions by using optical sensing technology. The photosensitive key detects pressing and releasing actions by replacing traditional mechanical contacts with optical components. When the key is pressed, the propagation path of light is blocked or changed, and a photosensitive receiving element located below the key receives light signals of different intensities or with or without light, thereby converting the optical change into an electrical signal and transmitting the electrical signal to a control chip of a device to identify the operation of the key. Today, various computer input devices use photosensitive keys, such as photosensitive key mice.

[0003] Because there is no wear and tear problem of mechanical contacts, the service life of the photosensitive key is usually much longer than that of the traditional mechanical micro key, and the double-clicking and malfunction caused by wear and tear of the key can be greatly reduced. The photosensitive key also has the advantages of fast response speed, high stability, and consistent key feel. However, the photosensitive key today is usually configured with a single light source. For example, if a photosensitive key mouse is equipped with multiple photosensitive keys, multiple light emitting members need to be matched for the multiple photosensitive keys.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] Furthermore, 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.

[0036] This utility model provides, for example 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 multiple photosensitive receiving elements 33 disposed on a computer input device. The main structure of this utility model includes: a light guide body 1, which is a transparent material structure capable of guiding light, and has a light source input end 11 and several light source output ends 12. The light source input end 11 is close to the light-emitting element 31 (e.g., an LED light-emitting element 31) of the computer input device, and the light-emitting element 31 illuminates the light source input end 11. The light source output ends 12 face the mouse optical IC 32 or photosensitive receiving elements 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 several light source output ends 12, and illuminate the mouse optical IC 32 or photosensitive receiving elements 33 near the light source output ends 12. To avoid light refraction and loss, the light guide body 1, the light source input end 11, and the light source output ends 12 are integrally formed.

[0037] It should be noted that the light-sensitive button 231 is usually configured with a light source alone. For example, if a mouse is equipped with multiple light-sensitive buttons 231, multiple light-emitting members 31 need to be provided for the multiple light-sensitive buttons 231. Such a structure design will inevitably increase the power consumption of the mouse and increase the production cost of the mouse.

[0038] The present application disperses the light source of the single light-emitting member 31 to the light source output end 12 through the light guide member body 1, and provides light sources for multiple light-sensitive receiving elements 33 with different function definitions. Only one single light source is needed to realize the light control function of the overall device, effectively reducing the energy consumption and production cost of the device.

[0039] Further, as shown in Figure 1 , Figure 2 and Figure 3 , the light guide member body 1 is provided with a plurality of light guide extension members 13, and the light source output end 12 is arranged at the end of the light guide extension member 13 away from the light guide member body 1. The light guide member body 1, the light guide extension member 13, the light source input end 11 and the light source output end 12 are integrally formed. The light guide extension member 13 can be a plastic column structure or a structure with fixed shape.

[0040] In some embodiments, the light guide extension member 13 is a light guide fiber. One end of the light guide fiber is connected to the light guide member body 1, and the other end is directed towards the mouse optical IC 32 or the light-sensitive receiving element 33 of the computer input device. The light guide fiber can be adjusted to bend according to the internal structure of the computer input device to realize end-to-end light transmission, facilitating production and assembly.

[0041] Further, as shown in Figure 2 and Figure 3 , the light source input end 11 is provided with an inner concave circular arc notch 111 for accommodating the light-emitting member 31. The inner concave circular arc notch 111 can better surround the light-emitting member 31, so that the light source emitted by the light-emitting member 31 can be as much as possible to illuminate the light guide member body 1, avoiding light scattering and affecting the utilization rate of light.

[0042] Further, the side wall of at least one of the light guide member body 1 and the light guide extension member 13 is provided with a light blocking layer for preventing light scattering. It can be understood that the light guide member body 1 is made of transparent material, and the side of the light guide member body 1 is prone to light scattering, which may lead to insufficient light at the light source output end 12. Further, it will affect the effective utilization rate of the light source output by the light-emitting member 31. Therefore, the light blocking layer is arranged on the side wall of at least one of the light guide member body 1 and the light guide extension member 13, and the light source originally scattered from the side wall of the light guide member body 1 and the light guide extension member 13 is reflected back. In this way, the effective utilization rate of the light source output by the light-emitting member 31 is improved.

[0043] Further, the light blocking layer is a metal plating layer. For example, aluminum plating layer, chromium plating layer and silver plating layer all have better light reflection performance. The light rays of the light emitting element 31 can be effectively reflected to avoid the light source from scattering out of the side wall of the light guide body 1 and the light guide extension 13, thereby effectively improving the utilization rate of the light source.

[0044] Further, the light guide body 1 is made of organic glass. It should be noted that the organic glass is called polymethyl methacrylate (PMMA). PMMA has excellent optical transparency, and the light transmittance is as high as about 92%, and the refractive index is about 1.49, which can make the light propagate efficiently therein. And it can be made into various complex shapes by injection molding, extrusion and other processes, 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 needs of the light-sensitive keys 231 of the device.

[0045] Moreover, the density of the organic glass is relatively low, about 1.19 g / cm 3 , and the texture is light, which is convenient for installation and use. The organic glass has good weather resistance and can maintain good performance under different environmental temperature and humidity conditions, and is not easy to yellow and brittle. For example, the light guide plate used in outdoor advertising light boxes can withstand long-term sun and rain without affecting the light guide effect.

[0046] As shown in Figure 4 and Figure 5 , the second aspect of the present application provides a single light source pure digital signal mouse, which is a common computer external input device for helping users to control the computer. It comprises a mouse shell 2, a circuit board 3 and a light guide body 1 as described in any one of the first aspect, the mouse shell 2 is provided with a plurality of keys 231; the circuit board 3 is arranged in the mouse shell 2, and the circuit board 3 is provided with a light emitting element 31, a mouse optical IC 32 and a plurality of light-sensitive receiving elements 33; the light guide body 1 is arranged in the mouse shell 2, the light source input end 11 on the light guide body 1 is correspondingly arranged with the light emitting element 31, the mouse optical IC 32 is correspondingly arranged with one of the plurality of light source output ends 12 on the light guide body 1, and the plurality of light-sensitive receiving elements 33 are correspondingly arranged with the light source output ends 12, and the keys 231 are used to open or block the channel between the light-sensitive receiving elements 33 and the light source output ends 12.

[0047] It should be noted that the light-sensitive keys 231 replace the traditional mechanical contacts to detect the pressing and releasing actions through the optical assembly. When the keys 231 are pressed, the propagation path of the light will be blocked or changed, and the light-sensitive receiving elements 33 located below the keys 231 will receive light signals of different intensities or without 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 keys 231.

[0048] Further, as shown in Figure 4 and Figure 5 , the mouse shell 2 comprises: a lower shell 21, a middle shell 22 and an upper shell 23, the bottom of the lower shell 21 is provided with a through hole 211, the lower shell 21 is provided with an optical lens 212 at a position corresponding to the through hole 211, one side of the optical lens 212 is provided with a light source input end 11, and the mouse optical IC 32 is arranged correspondingly to the optical lens 212; the middle shell 22 is arranged on the lower shell 21, the middle shell 22 is connected with the lower shell 21 to form a containing cavity, and the circuit board 3 is arranged in the containing cavity; the upper shell 23 is arranged on the middle shell 22, and at least one key 231 is arranged on the upper shell 23; wherein the key 231 is provided with a light blocking sheet 2311, and the light blocking sheet 2311 extends to a channel between the light-sensitive receiving element 33 and the light source output end 12. The light blocking sheet 2311 is used for shielding or changing the propagation path of the light output from the light source output end 12. The light-sensitive receiving element 33 located below the key 231 will receive light signals of different intensities or without 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.

[0049] Further, as shown in Figure 5 , the key 231 is provided with a first magnetic attraction piece 41, the middle shell is provided with a second magnetic attraction piece 42 at a position corresponding to the first magnetic attraction piece 41, the first magnetic attraction piece 41 and the second magnetic attraction piece 42 repel or attract each other to form a reset structure 4, and the reset structure 4 is used for resetting the key 231. The reset structure 4 formed by the first magnetic attraction piece 41 and the second magnetic attraction piece 42 can improve the damping touch feeling when the key 231 is actuated, and can effectively improve the touch experience of the user.

[0050] In summary, the application provides a light guide member body 1, a single light source pure digital signal mouse and a light control method. The light guide member body 1 disperses the light source of a single light emitting member 31 to a plurality of light source output ends 12, and provides light sources for a plurality of light-sensitive receiving elements 33 with different function definitions.
