Description

Technical Field

[0001] The present invention relates to the technical field of display equipment, and in particular to a key panel indicator light shading body and a light shading method. Background Art

[0002] With the development of special display equipment, such as Figure 1 As shown, in addition to the light-emitting fonts or graphics engraved on the button, a button indicator light is also added for the equipment operator to observe the equipment operating status and related information. At the same time, the operator makes corresponding operations based on the information corresponding to the indicator light. The conventional design of the button indicator light is to design a corresponding shading structural feature on the structure of the button panel, and to isolate light through the structural feature, so as to achieve the effect of isolating light between lights and preventing light from crossing and focusing light.

[0003] However, the above-mentioned integrated conventional design often has the following defects:

[0004] 1. The integrated design of the panel shading body will make the structural parts complicated, increase the processing difficulty and thus increase the processing cost;

[0005] 2. The integrated design of the panel shading body has the risk of light leakage and bottom cross-light, and the consistency of product status cannot be achieved;

[0006] 3. The integrated design of the panel shading body makes it difficult to quickly and accurately isolate and locate the faulty lamp bead when the key panel fails, which increases the time for personnel to troubleshoot;

[0007] 4. The integrated design of the panel shading body has certain wall thickness requirements and cannot be applied to key products with a small internal space in the key panel structure cavity.

[0008] Therefore, there is an urgent need to provide a key panel indicator light shielding body to solve the above technical problems. Summary of the invention

[0009] One of the purposes of the present invention is to provide a key panel indicator light shielding body, which is compatible with a small-sized key panel, has a good light shielding effect and a wide range of applications.

[0010] Another object of the present invention is to provide a method for shading a key panel indicator light. The method can effectively prevent light leakage from the key indicator light or light from the bottom, and also simplifies the overall structural features, reduces processing costs, and improves design versatility.

[0011] In order to achieve the above-mentioned objectives, on one hand, the present invention provides a key panel indicator light shield, which includes a light shield body body, and an indicator light giving groove for installing a second indicator light is provided on the light shield body body. When the light shield body body is detachably installed on the key circuit board, it can completely separate the light beams of different colors emitted by the adjacent first indicator light and the second indicator light, and a pressing stroke cavity is reserved between the top surface of the light shield body body and the light guide column of the second indicator light installed on the key body.

[0012] Preferably, the outer surface of the light shielding body is formed with a matching surface that can fit with adjacent components on the key panel.

[0013] Preferably, the outer surface corners of the light-shielding body are all rounded.

[0014] Preferably, the inner corners of the indicator light yielding groove are all formed with rounded corners.

[0015] Another aspect of the present invention provides a key panel indicator light shading method, wherein the key panel indicator light shading method uses the key panel indicator light shading body as described above to shade the key panel indicator light.

[0016] Preferably, the method includes: first, covering the light-shielding body onto the second indicator light so that the second indicator light is completely located in the indicator light yielding groove; then, fixing the bottom of the light-shielding body onto the key circuit board so that it separates the first indicator light and the second indicator light that can emit light beams of different colors; finally, when installing the key body, a pressing stroke is reserved between the light-shielding body and the light guide column of the second indicator light.

[0017] According to the above technical solution, the present invention installs the light shield body onto the key circuit board with the lamp beads welded thereon. When the key panel is powered on, the light shield body will separate the light beams of the first indicator light and the second indicator light of different colors, and there will be no risk of light crosstalk at the bottom of the light shield body. At the same time, in order to facilitate key pressing, the light guide column of the indicator light is also reserved with a press travel margin according to the key device needs.

[0018] Other features and advantages of the present invention will be described in detail in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0031] In the present invention, unless otherwise stated, directional words such as "inside, outside, top, bottom" contained in the terms merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0032] See also Figure 2 and Figure 5 On one hand, the present invention provides a key panel indicator light shielding body, the key panel indicator light shielding body comprises a light shielding body body 1, the light shielding body body 1 is provided with an indicator light giving slot 2 (such as Figure 3 When the light shielding body 1 is detachably mounted on the key circuit board 3, it can completely separate the light beams of different colors emitted by the adjacent first indicator light 41 and the second indicator light 42, and a pressing stroke cavity (such as Figure 4 shown).

[0033] Through the above technical solution, the light shield body 1 is installed on the key circuit board 3 with the lamp beads welded. When the key panel is powered on, the light shield body 1 will separate the light beams of the first indicator light 41 and the second indicator light 42 of different colors, and there will be no risk of cross-light at the bottom of the light shield body 1. At the same time, in order to facilitate key pressing, the light guide column 6 of the indicator light is also reserved with a press stroke margin according to the key device. In addition, the light shield body 1 can also make the space volume required for independent processing smaller, and can also be made of metal or composite materials according to different environmental requirements without the need to be consistent with the panel material, thereby achieving different user needs such as weight reduction, light focusing, and light transmission.

[0034] In this embodiment, in order to enable the key panel indicator light shield to be more closely attached to adjacent components to avoid light leakage affecting the light shielding effect, preferably, the outer surface of the light shield body 1 is formed with a matching surface that can fit adjacent components on the key panel.

[0035] When the shade body 1 is mounted on the key circuit board 3 , in order to prevent the sharp outer contour from scratching the surrounding parts or cutting the operator's hands during manual installation, the outer surface corners of the shade body 1 are preferably chamfered.

[0036] Similarly, the indicator light is also fragile and can be easily damaged when it comes into contact with sharp objects, squeezed or collided with, which not only delays the assembly time, but also increases the production and processing costs. In order to avoid this situation, it is preferred that the corners of the indicator light yielding groove 2 are chamfered.

[0037] In addition, the present invention also provides a key panel indicator light shading method, which uses the key panel indicator light shading body to shade the key panel indicator light.

[0038] The specific operation method is: first, the light-shielding body 1 is covered on the second indicator light 42, so that the second indicator light 42 is completely located in the indicator light yielding groove 2; then, the bottom of the light-shielding body 1 is fixed to the key circuit board 3, so that it can separate the first indicator light 41 and the second indicator light 42 that can emit light beams of different colors; finally, when installing the key body 5, a pressing stroke is reserved between the light-shielding body 1 and the light guide column 6 of the second indicator light 42.

[0039] By installing the light shielding body 1 on the key panel, the risks of light leakage from the key indicator light and light cross-talk from the bottom are solved, which can lay a solid foundation for the design and manufacture of similar products. At the same time, the independent light shielding body has a simple structure, low processing cost, and small structural space requirement, which is convenient for assembly and manufacture during the production process. In the actual production and processing process, the corresponding indicator light can be designed with a corresponding type of light shielding body, which can be directly borrowed in the subsequent research and development process without repeated design, thereby improving the design efficiency.

[0040] In addition, the application of the above-mentioned button panel indicator light shielding body not only saves design, manpower and financial costs, reduces the risk of product damage and delayed delivery caused by rework of the button panel indicator light due to light leakage or cross-light, but also can improve the product qualification rate, ensure status consistency, guarantee the product production cycle, and enhance the product's competitiveness in the market.

[0041] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0043] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
