Description

Technical Field

[0001] The utility model belongs to the technical field of light-emitting equipment and relates to a side-emitting optical fiber insert structure. Background Art

[0002] The side-emitting optical fiber emits soft and uniform light with a large emitting angle, and is very suitable for use in external signal lamps or decorative lamps of automobiles. Traditional lighting equipment of passenger cars is generally composed of optical fiber, light-guiding components, brackets and masks. During installation, the optical fiber is installed in the card slot of the bracket, and the mask is fixed and sealed on the bracket with glue. However, the solution requires the use of a gluing process, which is extremely complicated. In addition, the overall space of the lighting equipment after gluing is large, which is not convenient for people to install the lighting equipment later. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a side-emitting optical fiber insert structure which has a simple manufacturing process and occupies a small space.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A side-emitting optical fiber insert structure, comprising: a bracket, an optical fiber assembly is clamped in the bracket, a cover is provided on the bracket, and the cover is integrally injection-molded on the upper surface of the bracket.

[0008] In the above-mentioned side-emitting optical fiber insert structure, a groove for clamping the optical fiber assembly is provided inside the bracket.

[0009] In the above-mentioned side-emitting optical fiber insert structure, the overall shape of the groove is the same as the shape of the optical fiber assembly after bending.

[0010] In the above-mentioned side-emitting optical fiber insert structure, the width of the groove is 0.9 times the diameter of the optical fiber component.

[0011] In the above-mentioned side-emitting optical fiber insert structure, the optical fiber assembly includes a light-guiding glass filament and an optical fiber protective layer, and the optical fiber protective layer wraps the light-guiding glass filament.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the process of making the optical fiber insert structure, after people insert the optical fiber component into the corresponding position of the bracket, they need to place the bracket in a mold suitable for the optical fiber insert structure. Thereafter, the surface of the bracket used to install the optical fiber component is injection molded, and when the injection molding is completed, a cover will be formed on the side of the bracket facing the optical fiber component, and the cover will be bonded to the bracket, thereby avoiding the use of the gluing process and reducing the process steps of the optical fiber insert structure. Secondly, the gluing process step is also omitted, reducing the workload of workers. At the same time, it can also effectively reduce the thickness of the optical fiber insert structure, thereby making the space occupied by the optical fiber insert structure smaller.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1 — Figure 4 As shown, a side-emitting optical fiber insert structure of the present invention includes a bracket 100 , an optical fiber assembly 200 and a cover 300 .

[0020] An optical fiber component 200 is stuck in the bracket 100, and a cover shell 300 is provided on the bracket 100. The cover shell 300 is integrally injection-molded on the upper surface of the bracket 100. In the process of making the optical fiber insert structure, after people insert the optical fiber component 200 into the corresponding position of the bracket 100, the bracket 100 needs to be placed in a mold suitable for the optical fiber insert structure. Thereafter, the surface of the bracket 100 for installing the optical fiber component 200 is injection-molded, and when the injection molding is completed, a cover shell 300 will be formed on the side of the bracket 100 facing the optical fiber component 200, and the cover shell 300 will be bonded to the bracket 100, thereby avoiding the use of the gluing process, thereby reducing the process steps of the optical fiber insert structure. Secondly, the gluing process step is also omitted, reducing the workload of workers. At the same time, it can also effectively reduce the thickness of the optical fiber insert structure, thereby making the space occupied by the optical fiber insert structure smaller.

[0021] In the present invention, PUR is a self-repairing material, which refers to polyurethane material. It is a special polymer material. This self-repairing ability makes PUR self-repairing material have potential in many application fields, especially those materials that require wear resistance and durability, such as plastics, coatings, coatings, repair materials, and various applications in the automotive, construction and aerospace fields. It has high light transmittance and good fluidity, so that it will generate a lower temperature during the injection molding process.

[0022] The cover 300 is injection molded from PUR material. Therefore, when the cover 300 is injection molded, the temperature generated by the injection molding is relatively low, which will reduce damage to the optical fiber assembly 200 or will not affect the optical fiber assembly 200, that is, avoid the optical fiber assembly 200 from being hot-melted.

[0023] Both ends of the optical fiber assembly 200 have optical fiber light input ports (not marked in the figure). Furthermore, each of the optical fiber light input ports (not marked in the figure) is provided with a wrapping layer 210. During the injection molding process, people need to wrap the wrapping layer 210 around the optical fiber light input port (not marked in the figure) to prevent the PUR material from being contaminated on the optical fiber light input port (not marked in the figure) during the injection molding process, thereby ensuring the stability of the connection between the optical fiber assembly 200 and the external device.

[0024] The inside of the bracket 100 is provided with a groove 110 for clamping the optical fiber assembly 200. During installation, people need to clamp the optical fiber assembly 200 in the groove 110 of the bracket 100 so that the optical fiber assembly 200 is not easily dislocated relative to the bracket 100 during the injection molding process of the bracket 100.

[0025] The overall shape of the groove 110 is the same as the shape of the optical fiber component 200 after being bent. During installation, people can bend the optical fiber component 200 into a required shape as needed, and make the shape of the groove 110 the same as the shape of the optical fiber component 200, so that the optical fiber component 200 can be smoothly inserted into the groove 110. In this way, when the optical fiber component 200 is illuminated, a light source of a corresponding shape will be presented to increase the beauty of the optical fiber insert structure.

[0026] When people insert the optical fiber assembly 200 into the groove 110, since the width of the groove 110 is 0.9 times the diameter of the optical fiber assembly 200, an interference fit between the optical fiber assembly 200 and the groove 110 can be achieved, so that the optical fiber assembly 200 can be stably stuck in the bracket 100.

[0027] The optical fiber assembly 200 includes a light-guiding glass fiber 220 and an optical fiber protective layer 230. The optical fiber protective layer 230 wraps the light-guiding glass fiber 220. The optical fiber protective layer 230 can better protect the light-guiding glass fiber 220. Secondly, the optical fiber protective layer 230 is light-transmitting, and the cover 300 made of PUR material also has a good light-transmitting effect. In this way, the light generated by the light glass fiber can pass through the optical fiber protective layer 230 and the cover 300 in turn, thereby achieving the purpose of generating light by the optical fiber insert structure.

If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
