DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0020] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0021] Embodiment

[0022] As Figures 1-5 shown, in this embodiment, a light guide for preventing light leakage during housing assembly is mainly disclosed, which has a simple and reliable structure and is convenient for replacement and assembly. It includes a light guide body 1 and a mounting frame 2. One end of the light guide body 1 is for light introduction, and the other end is for light export. The mounting frame 2 is provided with a plurality of mounting channels 20 for mounting the light guide body 1. A buckle 21 for clamping and fixing the light guide body 1 is movably arranged in the mounting channel 20, and a lever 22 for releasing the clamping of the light guide body 1 and the buckle 21 is connected to the buckle 21. Specifically, the mounting channels 20 are relatively independent and are arranged in parallel side by side at equal intervals, ensuring that light is only exported through the light guide body 1 and effectively avoiding light leakage between adjacent light guide bodies 1. An avoidance groove for the movement of the buckle 21 is opened at the top of the mounting channel 20. When the light guide body 1 is installed, the buckle 21 is deformed by the abutment of the light guide body 1, so that the light guide body 1 can be smoothly inserted into the mounting channel 20. When the light guide body 1 is pushed in place, the buckle 21 returns to its original shape elastically and clamps with the light guide body 1 to prevent the light guide body 1 from withdrawing from the mounting channel 20, realizing the fixation of the light guide body 1. The lever 22 and the buckle 21 form a lever structure. When it is necessary to pull out the light guide body 1, press the lever 22 to make the buckle 21 tilt up and release the clamping with the light guide body 1, and then the light guide body 1 can be smoothly withdrawn from the mounting channel 20. The operation is simple, and the light guide body 1 can be freely combined with different mounting channels 20, improving the flexibility and applicability of the device.

[0023] Furthermore, in specific implementation, as Figure 5 shown, in the above light guide body 1 provided in the embodiment of the present invention, an inclined reflecting surface 12 is provided near the light introduction end for changing the light conduction direction. The end surface of the light export end of the light guide body 1 is a frosted surface 13, which can effectively diffuse light, improve the uniformity of light, and ensure the softness and visual effect of the light source.

[0024] Furthermore, in specific implementation, as Figure 3 shown, a light shielding plate 3 is provided on the above mounting frame 2 of the embodiment of the present invention. The light shielding plate 3 is arranged above the interval between adjacent mounting channels 20. It should be noted that since an avoidance groove for the movement of the buckle 21 is opened at the top of the mounting channel 20, the setting of the light shielding plate 3 can effectively prevent the blocking of light propagation and further avoid light leakage between adjacent mounting channels 20, which helps to improve the overall light efficiency and visual experience of the device.

[0025] Furthermore, in the specific implementation, Figures 1-2 As shown, the above-mentioned provided in the embodiment of the utility model also includes a panel 4, the panel 4 is bolted with a circuit board 5, the circuit board 5 is connected with a light-emitting element 51 close to the light-introducing end of the light guide 1, and the mounting frame 2 is bolted to the panel 4; specifically, a through hole is opened on the panel 4 for exposing the light-emitting end of the light guide 1, and the circuit board 5 and the mounting frame 2 are both bolted to the panel 4, which is convenient for maintenance and replacement; it is only necessary to bring the light-introducing end of the light guide 1 close to the light-emitting element 51 (such as a chip LED) on the circuit board 5, so that the light guide occupies a small space on the circuit board 5.

[0026] Furthermore, in the specific implementation, Figure 5 As shown, the light guide 1 provided in the embodiment of the utility model is made of a transparent plastic material through mold casting; excellent light transmittance is ensured, and at the same time, mold casting production can ensure that the shape and quality of each light guide 1 are consistent, thereby improving the overall product quality; it should be noted that during mold casting, the upper surface of the molded light guide 1 and the reflective surface 12 must not have a mold line, thereby effectively avoiding light loss.

[0027] Furthermore, in the specific implementation, Figure 5 As shown, the side wall of the light guide 1 provided in the embodiment of the utility model is provided with a retaining buckle 11 which cooperates with the buckle 21. The retaining buckle 11 is integrally formed with the light guide 1, which ensures that the light guide 1 is more stable during installation, reduces the loosening of components due to factors such as vibration, and improves the overall safety and reliability. Specifically, the retaining buckle 11 includes an insertion surface which cooperates with the buckle 21 in a wedge shape and an abutment surface which is engaged with the buckle 21.

[0028] Furthermore, in a specific implementation, the above-mentioned buckle 21, lift block 22 and mounting frame 2 provided in the embodiment of the utility model are integrally formed, which effectively reduces the complexity of component connection, improves production efficiency, and reduces potential failure points caused by assembly, thereby improving the stability of the overall structure.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
