Abstract
Description
Technical Field
[0001] This utility model relates to light sources, and more particularly to a light guide structure and an electronic product having the light guide structure. Background Technology
[0002] Light-emitting diodes (LEDs) are known as the fourth generation of light sources. Due to their energy-saving, environmentally friendly, safe, long lifespan, low power consumption, low heat generation, high brightness, waterproof, miniaturized, shockproof, easily dimmed, focused beam, and easy maintenance characteristics, they are widely used in various fields such as indicators, displays, decorations, backlights, and general lighting. However, LEDs are surface-mount devices (SMDs), located on the surface of a substrate. Therefore, LED light sources are generally embedded deep within products, limiting their visual appearance. Consequently, structures similar to light guides are often necessary.
[0003] Since the LED light source is built into the interior of the product, when using a light guide column for light guiding, it is necessary to prevent external water from seeping into the product from the edge of the light guide column and causing damage to the internal components such as the substrate. Therefore, when installing a structure similar to a light guide column, the waterproof requirements of both the light guide column and the product must be considered.
[0004] In addition, existing waterproof light guide structures usually adopt a split design, that is, the light guide structure is installed first, and then the rubber parts (such as rubber waterproof rings) are installed to achieve waterproofing.
[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0043] The embodiments of this application will now be described with reference to the accompanying drawings.
[0044] First aspect of the embodiments
[0045] This application provides a light guide structure. Figure 1 This is a schematic diagram of the light guide structure 100 according to an embodiment of this application, as shown below. Figure 1 As shown, the light guide structure 100 includes a light guide portion 110, a guide portion 120, and a fixing portion 130.
[0046] Figure 2 This is a cross-sectional schematic diagram of the light guide structure 100 according to an embodiment of this application, as shown below. Figure 1 and Figure 2As shown, in the light guide structure 100, the light guide portion 110 has a light incident surface 111 and a light exit surface 112. The guide portion 120 is disposed around the light guide portion 110 such that the light exit surface 112 is exposed. The fixing portion 130 is disposed on the light guide portion 110 and is located on the side of the guide portion 120 near the light incident surface 111.
[0047] In the above embodiment, the light guide portion 110, the guide portion 120, and the fixing portion 130 are set to a color that is translucent, thereby achieving a waterproof effect without affecting the light guiding function of the light guide structure 100.
[0048] Figure 2 The arrows in the image indicate the immersion path of the light guide structure 100 after it is assembled into the product, such as... Figure 1 and Figure 2 As shown, when water is immersed, the immersed water will flow along the outer side of the light guide 110, the guide 120, and the fixing part 130, such as... Figure 2 As indicated by the middle arrow, the water immersion path is lengthened due to the significant bends in the path, thus achieving an IPX7 waterproof rating.
[0049] The light guide structure 100 provided in this application embodiment integrates waterproof components onto the light guide components to form a component called light guide structure 100. This eliminates the need for additional waterproof components, reduces the number of components and assembly steps, and improves product production efficiency. Furthermore, by not using rubber materials to achieve waterproofing, the problem of waterproofing failure due to rubber aging is avoided.
[0050] Furthermore, when the light guide structure 100 is assembled onto the product, the fixing part 130 can also more securely fix the light guide structure 100 in the product, preventing the light guide structure 100 from rotating in the product, thereby avoiding defects such as flash on the product shell.
[0051] In some embodiments, such as Figure 2 As shown, the guide portion 120 has a first wall portion 121 and a second wall portion 122, wherein an included angle is formed between the first wall portion 121 and the second wall portion 122.
[0052] like Figure 1 and Figure 2As shown in the embodiment of this application, the guide portion 120 has a bent shape as an example. However, this application is not limited to this. In actual applications, the first wall portion 121 and the second wall portion 122 can also be flat and without bending. The included angle formed between the first wall portion 121 and the second wall portion 122 can be a right angle or another angle, depending on the structure and needs of the electronic product on which the light guide structure 100 is installed. This application does not impose any restrictions on this. For example, the shape of the guide portion 120 can be formed to match the shape of the light emitting surface 122 of the light guide portion 110. Thus, the guide portion 120 can achieve a good waterproof effect for light guide portions 110 of different shapes, improving the applicability of the light guide structure 100.
[0053] In the above embodiment, the extending direction of the fixing part 130 is parallel to the extending direction of the second wall part 122. By providing a fixing part 130 parallel to the second wall part 122, when the light guide structure 100 is assembled in the product, the fixing part 130 can make the light guide structure 100 more stable, preventing the light guide structure 100 from shaking in the product and causing defects such as shell burrs. This application is not limited to this; depending on the needs of the electronic product in which the light guide structure 100 is installed, the fixing part 130 may also be configured to have a certain angle relative to the second wall part 122, etc.
[0054] In some embodiments, such as Figure 2 As shown, one end of the fixing part 130 is connected to the guiding part 120, and the other end extends toward the light incident surface 111. In practical applications, to accommodate the different shapes of light guide structures required by different product models, the extending direction of the fixing part 130 may not be parallel to the second wall part 122, but may extend toward the light incident surface 111. This ensures that the light guide structure 100 maintains good stability when adapted to different products.
[0055] like Figure 1 and Figure 2 As shown, in the above embodiment, the outer surface S1 of the fixing part 130 and the outer surface S2 of the guide part 120 are on the same plane, that is, the outer surface S1 of the fixing part 130 and the outer surface S2 of the guide part 120 are flush, but this application is not limited to this. Figure 3 This is another schematic diagram of the light guide structure 100 according to an embodiment of this application; as shown Figure 3 As shown, in some embodiments, the outer surface S1 of the fixing portion 130 is closer to the light guide portion 110 than the outer surface S2 of the guide portion 120. That is, the outer surface S1 of the fixing portion 130 is recessed into the outer surface S2 of the guide portion 120.
[0056] Figure 4 Is it like this? Figure 3A schematic diagram of the waterproof path of the light guide structure 100 shown; as follows: Figure 4 As shown, according to Figure 3 The light guide structure 100 shown can form a water immersion path from a to a', relative to Figure 1 In the embodiment shown, where the outer surface S2 of the guide portion 120 is flush with the outer surface S1 of the fixing portion 130, the outer surface S1 of the fixing portion 130 is recessed into the outer surface S2 of the guide portion 120, forming an inwardly recessed stepped structure at the part where the guide portion 120 and the fixing portion 130 are in contact, which further lengthens the water immersion path and makes the light guide structure 100 have a better waterproof effect.
[0057] Figure 5 This is another schematic diagram of the light guide structure 100 according to an embodiment of this application; as shown Figure 5 As shown, in some embodiments, the outer surface S1 of the fixing portion 130 is further away from the light guide portion 110 than the outer surface S2 of the guide portion 120. That is, the outer surface S1 of the fixing portion 130 protrudes beyond the outer surface S2 of the guide portion 120.
[0058] Figure 6 Is it like this? Figure 5 A schematic diagram of the waterproof path of the light guide structure 100 shown; as follows: Figure 6 As shown, according to Figure 5 The light guide structure 100 shown can form a water immersion path from b to b', relative to Figure 1 The embodiment shown, in which the outer surface S2 of the guide portion 120 is flush with the outer surface S1 of the fixing portion 130, forms an outwardly protruding stepped structure at the part where the guide portion 120 and the fixing portion 130 are attached, which can further lengthen the water immersion path and make the light guide structure 100 have a better waterproof effect.
[0059] In the above embodiments, the light guide portion 110, the fixing portion 120, and the guiding portion 130 are integrally formed. For example, the light guide portion 110, the fixing portion 120, and the guiding portion 130 are integrally injection molded from materials such as PA (polyamide) and ABS (acrylonitrile-butadiene-styrene copolymer). For specific materials and injection molding processes, please refer to relevant technologies in the field. This application does not limit these aspects.
[0060] Therefore, by integrating the light guide 110 for guiding light, the guide 120 for waterproofing, and the fixing part for fixing into the same component, not only is the light guiding function guaranteed and the waterproofing and stability enhanced, but the number of parts and assembly steps are also reduced, thus improving the efficiency of product assembly.
[0061] According to the light guide structure 100 provided in the embodiments of this application, waterproof parts are integrated onto light guide parts to form a light guide structure, eliminating the need for additional waterproof parts, reducing the number of parts and assembly steps, and improving product production efficiency.
[0062] Furthermore, the guide part 120 and the fixing part 130 form a water immersion route with a larger turning radius and a longer path, which can achieve a better waterproof effect. In addition, the waterproof purpose is achieved without using rubber material, which can also avoid the problem of waterproof failure due to rubber aging.

A light guide structure 100 as described in the first aspect embodiment is also disposed above the circuit board 200. The light guide structure 100 conducts the light emitted by the light source 201. The circuit board 200 is fixed to the housing 300 by a fastening member 400, such as a screw, which is not limited in this application.
[0066] like Figure 7 As shown, the electronic product 10 also includes: a housing 300, which has a fixing groove H. The light guide structure 100 can be arranged as follows: Figure 7 The device is mounted in the fixing groove H via the fixing part 13 as shown.
[0067] After the light guide structure 100 is installed on the electronic product 10, the light guide part 110 can be evenly wrapped from four directions, thereby achieving all-round waterproofing.
[0068] In this application embodiment, the type of electronic product is not limited. Any electronic product that can use a light guide structure is included in the scope of electronic products in this application embodiment. For the specific composition and function of the electronic product, please refer to the relevant technology, which is omitted here.
