Abstract
Description
Technical Field
[0001] The utility model mainly relates to the field of light guide inlays, and specifically relates to a low-temperature shrinkage-resistant light guide inlay structure, a low-temperature shrinkage-resistant light guide inlay structure with an anti-shrinkage bracket, a luminous key light guide plate, and a night vision compatible key control panel. Background Art
[0002] The inlay structure of the light guide panel needs to have a certain structural strength when used in low-temperature scenarios. Usually metal or other high-strength materials are selected. To achieve the light guide function, a piece of transparent material needs to be embedded in the light guide position instead of the panel material.
[0003] In extremely harsh working scenarios with repetitive high and low temperature cycles, cracks may occur at the junction of the two materials in the inlay solution. This phenomenon is especially true when the inlay is large in size, with larger expansion and contraction sizes, and the probability of cracking is higher.
[0004] Normally, the panel is made of metal and the inlay is made of plexiglass. The thermal expansion coefficient of plexiglass is larger than that of metal. If there is no limit design, the inlay will shrink more at low temperatures, causing separation from the panel and surface cracking.
[0005] The utility model proposes a light-guiding inlay structure that is resistant to low-temperature shrinkage. Without changing the existing inlay form, the inlay and the panel are changed to coordinate with each other. The structure needs to be assembled in a low-temperature environment to limit the relative movement between the two materials and solve the problem of cracking at the joint at low temperatures.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items. Example
[0051] Reference Figure 1-10 , a low-temperature shrinkage-resistant light-guiding inlay structure, comprising the following structure:
[0052] The inlay 1 is made of a light-transmitting material, and a mounting protrusion 2 is fixedly arranged on one side of the non-light-emitting surface.
[0053] The panel 3 has a rectangular hole for light transmission fixedly formed on it, a groove 4 for embedding the inlay 1 is formed outside the rectangular hole, and a limiting protrusion 5 is fixedly formed inside the groove 4.
[0054] In this embodiment, the shape of the inlay 1 matches the shape of the rectangular hole on the panel 3 , the surface where the inlay 1 is assembled with the rectangular hole of the panel 3 is the first contact surface 6 , and the surface where the inlay 1 is assembled with the limiting protrusion 5 is the second contact surface 7 .
[0055] In this embodiment, the assembly protrusions 2 are distributed continuously and / or discontinuously on the non-light-emitting surface side of the inlay 1 .
[0056] In this embodiment, a raised feature is also designed around the panel 3 at positions corresponding to the raised features of the inlay 1, and its height is higher than that of the inlay 1, so as to reserve space for the expansion and contraction of the inlay 1 after assembly. The raised feature is continuous and / or discontinuous.
[0057] In this embodiment, the edges of the assembly joints of the inlay 1 and the panel 3 are chamfered.
[0058] The assembly of the inlay 1 and the panel 3 is carried out at a relatively low temperature, and the inlay 1 is forcibly embedded in the panel 3 by means of interference fit. The assembled view is shown in the accompanying drawings of the specification. Figure 3 As shown, at high temperature, since the expansion of the inlay 1 is greater, the inlay 1 is inside the panel 3, and the panel 3 limits the expansion of the inlay 1, the bonding surface between the inlay 1 and the panel 3 will not separate and crack.
[0059] At low temperatures, since the inlay 1 and the panel 3 are in an interference fit relationship, it is equivalent to storing a certain amount of elastic deformation. When the temperature drops, this part of the elastic deformation will be released, slowing down the separation of the contact surface. At the same time, at the contact position between the limiting protrusion 5 on the panel 3 and the assembly protrusion 2 on the inlay 1, the limiting protrusion 5 of the panel 3 shrinks less, and the shrinkage of the inlay 1 is limited by the upper protrusion structure of the panel 3, thereby reducing the dimensional shrinkage of the appearance of the inlay 1 and avoiding the separation and cracking of the inlaid joint.
[0060] A light guide inlay 1 structure with an anti-shrinkage ring 8 and anti-low-temperature shrinkage, comprising the following structures:
[0061] A convex feature is designed around the periphery of the inlay 1, which has a certain height and is at an appropriate distance from the outer contour. The convex structural feature is continuous and / or discontinuous.
[0062] The anti-shrinkage ring 8 is a ring-shaped structure made of high-strength material with a small thermal expansion system, and its outer contour matches the internal structure of the raised features of the inlay 1;
[0063] The panel 3 has a rectangular hole for light transmission fixedly formed on it, a groove 4 for embedding the inlay 1 is formed outside the rectangular hole, and a limiting protrusion 5 is fixedly formed inside the groove 4.
[0064] The assembly process is carried out at low temperature to reduce the difficulty of interference assembly and facilitate the stability of nesting at low temperature. Figure 1As shown, after assembly, the inlay 1 and the panel 3 are completely fitted together at the contact surface 1 and the contact surface 2 .
[0065] In this embodiment, the outside of the inlay 1 is nested in the rectangular hole on the panel 3 , and the inside of the bottom of the inlay 1 is nested with the outside of the anti-shrinkage ring 8 .
[0066] When the temperature drops, both the inlay 1 and the panel 3 shrink, and the shrinkage of the inlay 1 is greater than that of the panel 3. The inlay 1 shrinks faster, and the contact surface 1 faces the risk of separation and cracking. However, since the inlay 1 and the panel 3 are in an interference fit relationship at the contact surface 1, it is equivalent to storing a certain amount of elastic deformation, and the temperature reduction will release this part of the elastic deformation. At the same time, since the contact surface 2 is designed between the inlay 1 and the panel 3, at the contact surface 2, since the shrinkage of the inlay 1 is greater than that of the panel 3, the raised structure on the panel 3 limits the further shrinkage of the inlay 1 at low temperature, thereby reducing the shrinkage size of the inlay 1 at the contact surface 1, and then preventing the panel 3 and the inlay 1 from separation and cracking at the contact surface 1.
[0067] A light-emitting key light guide plate comprises a key, the surface of which is provided with a low-temperature shrinkage-resistant light guide inlay 1 structure and / or a low-temperature shrinkage-resistant light guide inlay 1 structure with an anti-shrinkage ring 8.
[0068] A night vision compatible key control panel 3 comprises an operation panel 3, the surface of which is provided with a low temperature shrinkage resistant light guide inlay 1 structure and / or a low temperature shrinkage resistant light guide inlay 1 structure with an anti-shrinkage ring 8.
[0069] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
