Description

Technical Field

[0001] This utility model belongs to the field of automotive interior and exterior lighting technology, specifically relating to an optical fiber connector light source module and automotive interior and exterior trim parts. Background Technology

[0002] Currently, automotive interior and exterior products are rapidly developing towards illumination. More and more OEMs need to use illuminated exteriors as a carrier to enhance the safety, aesthetics, and intelligent interaction capabilities of the entire vehicle. Due to their installation in relatively concealed areas on the exterior of the car, thin and long are the characteristics of these products. Therefore, the advantages of fiber optic products in terms of uniform light emission, brightness, color consistency, and flexibility can meet this requirement. As an important light-injection component of the luminous fiber, the fiber optic connector plays an important role in the luminous effect and ease of installation of the fiber. Existing fiber optic connectors are mostly designed for communication fibers and can usually only accommodate one fiber filament. However, the luminous fiber optics of automotive interior and exterior products usually need to contain hundreds of fiber filaments. The light-injection problem of luminous fibers cannot be solved by existing products and technologies. At the same time, existing fiber optic connectors do not have a snap-fit ​​sealing structure. Especially at the connection and driving position, existing fiber optic connectors cannot withstand high-temperature erosion. The entire light source has high power, high temperature, small lamp assembly size, and low heat dissipation efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fiber optic connector light source module that can solve the problem of light input to the light-emitting fiber, and has good high temperature resistance, anti-derailment sealing and heat dissipation, thus ensuring the light emission effect of the fiber optic cable.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a fiber optic connector light source module, characterized in that it includes:

[0005] An optical fiber connector assembly, comprising an optical fiber component and a connecting component, wherein the optical fiber component is used for emitting light, and the connecting component is installed at one end of the optical fiber component;

[0006] The fiber optic module assembly is connected to the fiber optic component via a connecting component. The fiber optic module assembly contains a light source, which is transmitted through the fiber optic component to make the entire fiber optic component emit light.

[0007] In the aforementioned fiber optic connector light source module, the fiber optic component includes an optical fiber and a sheath. The optical fiber is composed of multiple fiber filaments, which are arranged inside the sheath and assembled into a single optical fiber.

[0008] In the aforementioned fiber optic connector light source module, the fiber optic module assembly includes a heat sink, a top cover, a circuit board, and a light source. The top cover is mounted on the front of the heat sink, and the light source is mounted on the circuit board. The assembly consisting of the circuit board and the light source is installed in the mounting space formed between the heat sink and the top cover. One end of the optical fiber extends into the top cover, and the light source is aligned with the optical fiber.

[0009] In the aforementioned fiber optic connector light source module, the upper cover has multiple mounting pieces on its periphery, each mounting piece having a mounting groove, and a mounting protrusion that mates with the mounting groove is provided on the periphery of the heat sink.

[0010] In the aforementioned fiber optic connector light source module, a first rubber ring is also installed between the heat sink and the top cover.

[0011] In the aforementioned fiber optic connector light source module, a heat dissipation component is integrally connected to the rear of the heat sink, and the heat dissipation component consists of multiple spaced heat sinks.

[0012] In the aforementioned fiber optic connector light source module, the heat dissipation component is provided with a connector for connecting to an external control component, and the circuit board has pins located inside the connector.

[0013] In the aforementioned fiber optic connector light source module, the connector has an external mounting flange.

[0014] In the aforementioned fiber optic connector light source module, a thermal pad is also installed on the bottom of the circuit board inside the heat sink.

[0015] In the aforementioned fiber optic connector light source module, the connecting component includes a connector, a snap fastener, and a spring. One end of a single optical fiber is inserted into the connector, the snap fastener is fitted onto the connector, and the spring is fitted onto the connector, with both ends acting on the connector and the snap fastener respectively. The snap fastener is installed and connected to the upper cover.

[0016] In the aforementioned fiber optic connector light source module, the connector is made of metal.

[0017] In the aforementioned fiber optic connector light source module, the upper cover has protrusions, and the latching member has an L-shaped slot. After the fiber optic connector assembly is inserted into the upper cover of the fiber optic module assembly, the latching member is pushed to the bottom and rotated so that its slot engages and is fixedly connected with the protrusions of the upper cover.

[0018] In the aforementioned fiber optic connector light source module, a second rubber ring is installed between the upper cover and the connector.

[0019] An automotive interior and exterior trim component is equipped with the aforementioned fiber optic connector light source module.

[0020] Compared with the prior art, the advantages of this utility model are:

[0021] 1. Fiber optic connectors are made of high-temperature resistant materials, usually metal, which can effectively withstand high temperatures (150℃) and achieve rapid heat conduction. In addition, the fiber optic connectors can ensure that the glue at the fiber connection will not oxidize or corrode under high temperature conditions, thus ensuring that the light source fiber has a good light-emitting effect.

[0022] 2. The connector is equipped with a sealing ring and has a sealing and anti-loosening structure design when installed with metal buckles. The buckles contain springs that provide a tightening and buffering effect during assembly, making installation and disassembly convenient and easy.

[0023] 3. The use of heat sinks for heat dissipation greatly reduces the size and weight of the light source assembly, making the entire light source module lightweight while providing excellent heat dissipation. In addition, it prevents the heat generated by the circuit board and light source components from accumulating on the heat sink, which could lead to the failure or performance reduction of the light source components and thus affect the brightness of the fiber optic cable.

[0025] Figure 2 This is a schematic diagram of the internal structure of the assembled fiber optic connector light source module;

[0026] Figure 3 This is a structural diagram of the connector, clips, springs, and optical fiber assembly. Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] In the diagram, the following components are included: fiber optic connector assembly 100; fiber optic module assembly 200; fiber optic component 300; connector component 400; fiber optic cable 500; sheath 600; fiber optic filament 700; heat sink 800; top cover 900; circuit board 1000; light source 1001; mounting plate 1002; mounting slot 1003; mounting protrusion 1004; first rubber ring 1005; heat sink 1006; connector 1007; connector pin 1008; assembly flange 1009; connector 1010; buckle 1011; spring 1012; protrusion 1013; slot 1014; second rubber ring 1015; and thermal pad 1016.

[0029] like Figure 1 The fiber optic connector light source module shown here mainly consists of two parts: a fiber optic connector assembly 100 and a fiber optic module assembly 200. The fiber optic connector assembly 100 is composed of a fiber optic component 300 and a connecting component 400. The fiber optic component 300 is used for light emission, and the connecting component 400 is installed at one end of the fiber optic component 300 and its main function is for connection. The fiber optic module assembly 200 is connected to the fiber optic component 300 through the connecting component 400. The fiber optic module assembly 200 is mainly used for light emission and has a light source inside. The light source is conducted through the fiber optic component 300 and makes the entire fiber optic component 300 emit light.

[0030] Specifically, the optical fiber component 300 includes an optical fiber 500 and a sheath 600. In order to achieve a good light-emitting effect, in this patent, the optical fiber 500 is composed of multiple optical fiber strands 700. The multiple optical fiber strands 700 are arranged inside the sheath 600 and assembled into a single optical fiber 500. Here, the sheath 600 serves a protective function on the one hand, and on the other hand, it can integrate multiple optical fiber strands 700 into a single optical fiber 500. Furthermore, different irregular shapes of optical fibers 500 can be manufactured according to the shape of the sheath 600.

[0031] like Figure 2 As shown, as a further optimization, to facilitate light emission and heat dissipation, the fiber optic module assembly 200 includes a heat sink 800, a top cover 900, a circuit board 1000, and a light source 1001. The top cover 900 is mounted on the front of the heat sink 800, and the light source 1001 is mounted on the circuit board 1000. The assembly consisting of the circuit board 1000 and the light source 1001 is installed in the mounting space formed between the heat sink 800 and the top cover 900. One end of the optical fiber extends into the top cover 900 and the light source 1001 is aligned with the optical fiber. Here, the light source 1001 mainly provides the light source. The light emitted by the light source 1001 is transmitted through the optical fiber and then emits light. In this patent, the heat sink 800 provides mounting space for the light source 1001 and its main function is heat dissipation.

[0032] As a further optimization, to facilitate the disassembly and portable installation of the upper cover 900 and the heat sink 800, the upper cover 900 has multiple snap-fit ​​pieces 1002 on its periphery, and each snap-fit ​​piece 1002 has a snap-fit ​​groove 1003. The heat sink 800 has a snap-fit ​​protrusion 1004 on its periphery that mates with the snap-fit ​​groove 1003. When the snap-fit ​​protrusion 1004 snaps into the snap-fit ​​groove 1003, the upper cover 900 and the heat sink 800 are assembled. As a further optimization, in order to ensure good sealing performance, a first rubber ring 1005 is also installed between the heat sink 800 and the upper cover 900.

[0033] As a further optimization, the heat generated by the light source component can accumulate in the heat dissipation base, leading to light source component failure or performance degradation, thus affecting fiber optic brightness. To achieve efficient heat dissipation, a heat dissipation component is integrally connected to the rear of the heat dissipation base 800. The heat dissipation component consists of multiple spaced heat sinks 1006. To efficiently conduct the heat generated by the light source component 1001, a thermal pad 1016 is also installed at the bottom of the circuit board 1000 inside the heat dissipation base 800 in this patent. In this way, the heat generated on the circuit board 1000 can be conducted to the heat dissipation component through the thermal pad 1016 for rapid heat dissipation. In this patent, the entire heat dissipation base 800 is made of aluminum alloy and adopts a pin-column heat dissipation structure with 13 column-shaped heat sinks 1006 distributed on it for heat dissipation. This greatly reduces the size and weight of the light source assembly, making the entire light source module lightweight while having a good heat dissipation effect. In addition, it can prevent the heat generated by the circuit board 1000 and the light source component 1001 from accumulating in the heat dissipation base 800, thereby preventing the light source component 1001 from failing or its performance degradation, thus affecting fiber optic brightness.

[0034] To facilitate connection with external control components, the heat dissipation component is provided with a connector 1007 for connecting to the external control components. The circuit board 1000 has a pin 1008, which is located inside the connector 1007. The connector 1007 has a mounting flange 1009 on its outside. In use, the control component can be controlled by simply engaging the mounting flange 1009 and connecting it to the pin 1008.

[0035] like Figure 3As shown, another innovation of this patent is that the connecting component 400 includes a connector 1010, a latching component 1011, and a spring 1012. One end of a single optical fiber is inserted into the connector 1010. The latching component 1011 is fitted onto the connector 1010, and the spring 1012 is fitted onto the connector 1010, with both ends acting on the connector 1010 and the latching component 1011 respectively. The latching component 1011 is installed and connected to the upper cover 900. Here, the connector 1010 is made of a high-temperature resistant material for the optical fiber connector, generally a metal material, which can effectively withstand high temperatures (150℃). This solves the problem that the connector 1010 will not corrode under high-temperature conditions and ensures that the light source optical fiber has a good light-emitting effect. The latching component 1011 mainly serves as an intermediate connection, which can connect the entire optical fiber connector assembly 100 and the optical fiber module assembly 20. The components are connected together. For easy assembly and installation, the upper cover 900 has protrusions 1013, and the latching component 1011 has an L-shaped slot 1014. After the fiber optic connector assembly 100 is inserted into the upper cover 900 of the fiber optic module assembly 200, the latching component 1011 is pushed to the bottom and rotated so that its slot 1014 engages and is fixedly connected with the protrusions 1013 of the upper cover 900. Here, the L-shaped slot 1014 not only has an anti-detachment function, but also allows for quick assembly and connection of the latching component 1011 and the upper cover 900. To ensure good sealing performance at the connection, a second rubber ring 1015 is installed between the upper cover 900 and the connector 1010. Through the connector 1010, the latching component 1011, and the second rubber ring 1015, the required sealing and anti-detachment function can be achieved while being resistant to high temperatures.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
