[0032] As shown in FIGS. 1, 2 and 3, the light guide structure according to the embodiments of the present application comprises a base 10 and a light guide piece 20. Figure 1 and Figure 2 As shown in FIGS. 1, 2 and 3, the light guide structure according to the embodiments of the present application comprises a base 10 and a light guide piece 20.

[0033] Specifically, the base 10 is provided with a clamping groove 11 and a lead-out hole 12; the light guide piece 20 comprises a light guide column 21 and an elastic body 22 connected with each other, part of the light guide column 21 is arranged in the lead-out hole 12, the elastic body 22 is arranged in the clamping groove 11, and the elastic body 22 is in interference fit with the clamping groove 11.

[0034] In the above embodiment, the base 10 serves as an integral mounting base for providing support and stability; the light guide column 21 utilizes the principle of total reflection to conduct the light emitted by the light source from one end to the other end, the lead-out hole 12 is used for the light guide column 21 to pass through, providing a channel for the light to pass out or enter, the lead-out hole 12 can accurately position the vertical position of the light guide column 21, and the elastic body 22 is arranged in the clamping groove 11, so that the horizontal position of the light guide piece 20 can be limited by the clamping groove 11. Since the elastic body 22 has elasticity, it can adaptively deform according to the size of the clamping groove 11, automatically compensate for manufacturing errors and size changes during use, and avoid the light guide piece 20 from being loose from the base 10.

[0035] During assembly, the light guide column 21 is first inserted into the lead-out hole 12, and then the elastic body 22 is pressed into the clamping groove 11, so that the outer wall of the elastic body 22 tightly abuts the inner surface of the clamping groove 11, thereby realizing the assembly of the light guide piece 20 and the base 10.

[0036] It should be noted that the shape and size of the light-out hole 12 need to be matched with the light guide column 21 to reduce the loss of light, and when processing, the inner wall of the light-out hole 12 is allowed to have a small gap with the light guide column 21 to allow a small amount of displacement, so as to avoid excessive displacement to cause structural damage and light scattering.

[0037] The light guide column 21 is usually made of a high-transmittance material, and at the end of the light guide column 21 located outside the base 10, the end can be processed, for example, lens polishing, to optimize the exit angle of the light.

[0038] In a specific embodiment, the base is made of a plastic material. The elastic body 22 and the light guide column 21 are integrally formed and are both made of plastic.

[0039] According to the light guide structure of the embodiments of the present application, the elastic body 22 of the light guide member 20 is clamped in the clamping groove 11, and the elastic body 22 can be deformed under pressure. The clamping groove 11 cooperates with the elastic body 22, and when the elastic body 22 is clamped in the clamping groove 11, it can adapt to the processing error of the clamping groove 11 and be elastically deformed adaptively. Through the elastic restoring force of the elastic body 22, the light guide member 20 is always kept in the corresponding position, so that the light guide member 20 will not be displaced or fall off during use due to external force. At the same time, since the elastic body 22 has elastic force, it can also play a role in reducing vibration when the light guide structure is vibrated, avoiding functional failure of the light guide member 20 due to vibration or displacement. In addition, the elastic body 22 is in interference fit with the clamping groove 11, and the elastic body 22 and the clamping groove 11 are directly clamped to realize precise installation, without the need for additional fasteners, which can simplify disassembly and greatly save disassembly time and assembly difficulty.

[0040] As shown in FIGS. Figure 2 and Figure 4 In some embodiments, the clamping groove 11 is provided with a first limiting portion 30, the first limiting portion 30 and the light-out hole 12 are oppositely arranged, and the first limiting portion 30 abuts against the elastic body 22.

[0041] In detail, the first limiting portion 30 limits the movement of the elastic body 22 through the abutting action with the elastic body 22, avoiding displacement due to external force or vibration, and can indirectly provide additional support for the light guide column 21, effectively maintaining the correct position of the light guide column 21 and ensuring its stability in the light-out hole 12.

[0042] The first limiting part 30 can be provided in various structures, for example, the first limiting part 30 is configured as a transverse baffle plate, when the elastic body 22 is clamped in the clamping groove 11, the baffle plate is in contact with the elastic body 22 to prevent it from moving outward; the first limiting part 30 can also be provided in a tapered or stepped structure with different diameters, so that the elastic body 22 can only stay in a specific position, thereby effectively limiting the elastic body 22; the first limiting part 30 can also be provided with a buckle, when the elastic body 22 is clamped into the clamping groove 11, it is clamped by the buckle to prevent it from falling off.

[0043] As shown in Figure 2 and Figure 4 , in some embodiments, the clamping groove 11 includes opposite first and second side walls, the first side wall is provided with the lead-out hole 12, and the second side wall is provided with the first limiting part 30, and the elastic body 22 is spaced from the second side wall to define the first avoiding space 50.

[0044] In the above embodiments, the first and second side walls are oppositely arranged, the lead-out hole 12 is arranged on the first side wall, and the first limiting part 30 is provided on the second side wall, so that the first limiting part 30 can better support and limit the light guide column 21, improve the mechanical stability of the light guide column 21, and at the same time, during assembly, the protruding first limiting part 30 can serve as a positioning mark, making the assembly process more convenient, reducing the installation time, and playing a foolproof role. The first avoiding space 50 provides greater assembly flexibility, so that the elastic body 22 can be more easily adjusted and aligned during assembly in the clamping groove 11, ensuring the reliability of the overall structure.

[0045] As shown in Figure 2 and Figure 4 , in some embodiments, the first limiting part 30 includes first and second limiting subparts 31 and 32 connected to each other, the first limiting subpart 31 abuts against the side wall of the elastic body 22, and the second limiting subpart 32 abuts against the bottom wall of the elastic body 22 to space the elastic body 22 from the bottom wall of the clamping groove 11 to define the second avoiding space 60, and the second avoiding space 60 is communicated with the first avoiding space 50.

[0046] In the above embodiments, the first limiting subpart 31 abuts against the side wall of the elastic body 22 to provide lateral positioning, and the second limiting subpart 32 abuts against the bottom wall of the elastic body 22 to space the elastic body 22 from the bottom wall of the clamping groove 11 to define the second avoiding space 60, which can make the installation design of the light guide member 20 more flexible and reduce the overall weight of the base 10.

[0047] In some embodiments, the bottom wall of the clamping groove 11 is provided with a support part 40, and the support part 40 is located below the elastic body 22 and abuts against the elastic body 22.

[0048] AsFigure 4 As shown in the above embodiments, the support part 40 is located below the elastic body 22 and abuts against the elastic body 22, which can provide additional support force for the elastic body 22 to prevent it from being deformed or displaced too much due to stress, thereby improving the stability of the overall structure. At the same time, the elastic body 22 is in interference fit with the clamping groove 11, and the setting of the support part 40 can further enhance the tightness of this fit.

[0049] As shown in the above embodiments, the support part 40 is located below the elastic body 22 and abuts against the elastic body 22, which can provide additional support force for the elastic body 22 to prevent it from being deformed or displaced too much due to stress, thereby improving the stability of the overall structure. At the same time, the elastic body 22 is in interference fit with the clamping groove 11, and the setting of the support part 40 can further enhance the tightness of this fit.

At the same time, the elastic body 22 is in interference fit with the clamping groove 11, and the setting of the support part 40 can further enhance the tightness of this fit.

[0050] In the above embodiments, the first cross beam 221 and the two connecting arms 222 form a frame structure of the elastic body 22, which can enhance the overall strength of the elastic body 22 and avoid breaking or deforming due to stress. At the same time, the installation position of the light guide column 21 can be fixed by cooperating the connecting arm 222 with the second cross beam 23, ensuring the overall strength and stability of the light guide 20, and ensuring the installation accuracy of the light guide column 21. The second cross beam 23 is provided with the light guide column 21 for fixing the position of the light guide column 21, and by abutting against the first side wall, the connection stability of the light guide 20 and the base 10 is enhanced. The first cross beam 221 and the two connecting arms 222 form an elastic structure that allows a certain degree of deformation to adapt to minor errors during installation or use. The first sub-part 41 provides support for the first cross beam 221, improving the stability of the first cross beam 221 and preventing it from sinking or deforming due to stress. The second sub-part 42 provides support for the connecting arm 222, optimizing the stress distribution of the elastic body 22, improving the stability and service life of the light guide structure, and enhancing the elastic deformation capability of the elastic body 22.
