Background
Wireless router products have become increasingly a household necessity in today's society, and as the demand for internet access becomes more important, the performance and design of wireless routers connected to home terminals become more important. Meanwhile, the design of the router is gradually designed according to the direction of the furniture, the router is integrated into the layout of the family, the aesthetic property of the family layout is improved, and the router is the requirement of consumers.
The router is provided with an optical signal source for displaying related information, and in order to enable the optical signal to be displayed clearly and accurately and meet the requirement of improving the attractiveness of family layout, a certain structure needs to be arranged for assistance, so that the aim of attractiveness can be fulfilled. The housing of an electronic device such as a router is usually made of a plastic material, and due to the fact that plastic has light transmission, gaps and other factors, it is imperative to correctly guide out light emitted by an LED light source and eliminate irrelevant light pollution.
A current light guide structure is a light guide pillar, i.e., a snap-fit light guide structure, which is specifically shown in fig. 1 and 2, where fig. 1 is a specific structural diagram and fig. 2 is an assembly diagram. The light guide column is matched with the shell through the light emitting surface, ears on two sides of the light guide column, so that the light guide column is fastened, the light guide column is convenient to mount, and the light guide effect is good; however, the structure is only suitable for the situation that the light-emitting surface is small and the light guide column is narrow, once the light guide structure becomes wide and large, the clamping amount of ears at two sides needs to be enhanced, otherwise, the matching strength is difficult to ensure in batch production; in addition, if the card sum design is large, the problem that the card sum design is difficult to install and disassemble and cannot be replaced is faced.
Regarding the conventional hot-melt structure of the light guide column: the traditional light guide column hot melting structure is characterized in that the light guide column and the plastic machine body are melted together by heating and melting on the premise of depending on the matching of the light guide column and the plastic of the machine body, so that the fixing mode is firmer, but the operation is complicated, and later-stage disassembly and replacement cannot be carried out; meanwhile, for some special products, light can overflow from the welding position and is difficult to process, and in addition, the hot melting is limited by various factors such as plastic materials and the like.
In summary, the current light guiding structure has the following disadvantages: the structure is too complex and the installation is not firm; poor light guiding effect, inconvenient assembly and the like, and the mass production may result in uneven product quality and reduced customer satisfaction. The existing product is not beneficial to mass production due to the complex fixing structure, the screw fixing and assembling time is prolonged, the productivity is reduced, the cost is increased, and the benefit of an enterprise is reduced.

The specific technical problems are the light-emitting surface structure and the assembly structure shown in fig. 1.
In the improved scheme of the scheme, the structure is as follows: first, the light guide device includes a main body 1 for carrying a light source and a light guide part 2 located on the top of the main body 1.
The main body part 1 is used for placing a required point light source; after the point light source is placed on the main body 1, the light is irradiated on the light guide part 2, the light is guided to a predetermined position by the light guide part 2, and the light guide part 2 focuses light and prevents light overflow.
The light guide part 2 has a first feature surface 3 and a second feature surface 4, the first feature surface 3 is located on one side of the light guide part 2 facing the light source, and the second feature surface 4 is located on the opposite side of the first feature surface 3. That is, the light guide part 2 has two surfaces for guiding the light emitted from the point light source, and the first characteristic surface 1 faces the point light source, and the second characteristic surface 2 faces away from the point light source; these two faces are front and back faces located on both sides of the light guide portion 2. After the light is emitted by the point light source, the light irradiates the first characteristic surface 3, and the light finally guides to a preset area by passing through the first characteristic surface 3 for the first time and combining with the second characteristic surface 4 to form a preset light beam so as to achieve a preset effect.
Here, the light guide portion 2 and the main body portion 1 in this embodiment are L-shaped as a whole. That is, if the main body part 1 is horizontally placed, the light guide part 2 is vertically disposed, so that the light guide part 2 and the main body part 1 exhibit an L-shaped coupling structure. In this configuration, the point light source located on the main body 1 can directly emit light onto the first characteristic surface 3 of the light guide portion 2, and in this embodiment, the light guide portion 2 has one first characteristic surface 3 with a large area, and the first characteristic surface 3 can receive more light and can store all the light.
The second characteristic surface 4 is provided with a light-emitting part 5, the base part of the light-emitting part 5 is positioned on the second characteristic surface 4, and the tail end part of the light-emitting part 5 is provided with a light-emitting surface 6.
After passing through the first feature surface 3, the light emitted by the point light source is finally collected to the base of the light-emitting portion 5 in cooperation with the second feature surface 4, the light is transmitted along the base of the light-emitting portion 5 to the end portion, and finally collected to the light-emitting surface 6 at the end of the light-emitting portion 5, so that a required light beam is obtained on the light-emitting surface 6.
As shown in fig. 3 to 7, the first feature surface 3 and the second feature surface 4 are combined surfaces formed by combining a plurality of sub-planes at an angle. That is, the first feature surface 3 and the second feature surface 4 are not one plane but are surfaces composed of several different planes, and the first feature surface 3 and the second feature surface 4 are fitted to each other, and thus, sub-surfaces constituting the two surfaces are also fitted to each other.
The first characteristic surface 3 includes a first inclined surface 9 and a first straight surface 10, two surfaces of the first inclined surface 9 and the first straight surface 10 have an angle, specifically, the upper surface of the main body 1 is connected with the first inclined surface 9, then the first inclined surface 9 is connected with the first straight surface 10, the upper surface of the main body 1, the first inclined surface 9 and the first straight surface 10 together form an L-shaped surface, and the first characteristic surface 3 is a part of the L-shaped surface.
The second characteristic surface 4 is provided with a second inclined surface 11 and a second straight surface 12 corresponding to the first characteristic surface 3, and an angle is formed between the second inclined surface 11 and the second straight surface 12. Specifically, the lower surface of the main body 1 is connected to a second inclined surface 11, the upper end of the second inclined surface 11 is connected to a second straight surface 12, the lower surface of the main body 1, the second inclined surface 11 and the second straight surface 12 form an L-shaped surface, and the second feature surface 4 is a part of the L-shaped surface.
Under the matching reflection of the first inclined surface 9, the first straight surface 10, the second inclined surface 11 and the second straight surface 12, the light of the point light source entering from the first characteristic surface 3 is reflected and finally reaches the base of the light emergent portion 5.
Above the first straight surface 10, there is also provided a third inclined surface 14,
preferably, the first inclined surface 9 and the second inclined surface 11 are parallel to each other, and the first straight surface 10 and the second straight surface 12 are parallel to each other.
That is, both faces of the first inclined face 9 and the first straight face 10 have an angle identical to that of the second inclined face 11 and the second straight face 12.
Meanwhile, the third inclined surface 14 is also parallel to the first inclined surface 9 and the second inclined surface 11.
As shown in fig. 3 to 7, in relation to the assembly and fixation problem of the whole structure, in particular, the main body 1 is provided with a first elastic arm 7 and a second elastic arm 8 on both sides, the base parts of the first elastic arm 7 and the second elastic arm 8 are connected with both sides of the main body 1, and the bodies of the first elastic arm 7 and the second elastic arm 8 are separated from the main body 1 to form an arm-shaped structure.
This is different from the installation method shown in fig. 1 in the background art, and two elastic arms of the structure, namely the first elastic arm 7 and the second elastic arm 8, are of elastic structures.

In order to improve the ease of assembly, the first elastic arm 7 and the second elastic arm 8 have a difference in length therebetween. That is, the second elastic arm 8 is longer than the first elastic arm 7, or alternatively, the first elastic arm 7 is longer than the second elastic arm 8.
As a further improvement, the longer spring arm is set to have a smaller outer diameter than the longer spring arm.
That is, one case is: the second elastic arm 8 is longer than the first elastic arm 7, and is thinner, and the second elastic arm 8 is thinner than the first elastic arm 7;
another case is: the first elastic arm 7 is not only longer but also thinner than the second elastic arm 8, and the first elastic arm 7 is elongated than the second elastic arm 8.
The first elastic arm 7 in the first case and the second elastic arm 8 in the second case are short and thick, and mainly play a role in positioning the light guide structure in the assembling process, so that the light guide structure is prevented from rotating out of the working position after the assembling is finished;
and the rest elastic arms are more slender and better in elasticity, and are designed to have proper interference values during setting.
At the lower extreme of two elastic arms of first elastic arm 7 than second elastic arm 8, all design has the chamfer to smoothly enter into operating position (first muscle position 15 and second muscle position 16 and first stop muscle position 17 and second stop muscle position 18 department) when making things convenient for light guide structure to install. The chamfer makes the first elastic arm 7 more easily enter the working position than the second elastic arm 8 and is not easy to be separated. Thereby ensuring stability of the assembly.
As shown in fig. 3 to 7, the light emergent portion 5 is specifically disposed on the second straight surface 12, the light emergent portion 5 is a sheet-shaped structure, and the thickness of the light emergent portion 5 is gradually reduced from the base portion to the end portion. The cross section of the light emergent portion 5 has a certain length-width ratio, and specifically, the light guide portion 5 gradually decreases from the base to the end, mainly showing the thickness, and the degree of the decrease is determined according to actual conditions.
In order to avoid interference caused by light partially passing through the second feature surface 4, a light shielding sheet 13 for covering other areas outside the light emergent portion 5 is arranged on the second feature surface 4, and the light shielding sheet 13 is a mylar sheet.
