[0019] The present application will be further described below in conjunction with specific embodiments. Obviously, the embodiments described are only a portion of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative changes are within the scope of protection of the present application.
[0020] like Figure 1 and 2As shown, a simplified installation structure for an automotive lamp includes a light guide 1, a bracket 2, a light guide PCB 3, and a PCB board 5. The light guide 1 is mounted on the bracket 2, and has a first limiter at one end. The light guide PCB 3 is mounted on one side of the light guide 1, and the first limiter limits the light guide PCB 3 in a first direction and a second direction. The PCB board 5 is mounted on the bracket 2, and has a second limiter at one end. The second limiter limits the light guide PCB 3 in a third direction. The first direction, second direction, and third direction are perpendicular to each other.
[0021] A first limiting portion is provided on the light guide 1, which can position the light guide PCB 3 at one end thereof so that the LED on the light guide PCB 3 corresponds to the light guide 1, and the light emitted by the LED on the light guide PCB 3 can be guided out through the light guide 1. The second limiting portion on the PCB board 5 can further limit the position of the light guide PCB 3, and thus fix the light guide PCB 3. No additional riveting or screw 6 structure is required, which simplifies assembly, improves production efficiency, and does not require additional riveting or locking tooling, saving costs.
[0022] like Figure 2 As shown, to facilitate the installation of the light guide 1, in some embodiments, the bracket 2 is provided with a hook 21 structure, and the light guide 1 is installed on the bracket 2 via the hook 21 structure. Specifically, the bracket 2 can be configured as a structure with a U-shaped cross section, and the light guide 1 is installed at the bottom of the bracket 2. The hook 21 can confine the light guide 1 therein to prevent it from slipping.
[0023] like Figure 2 As shown, specifically, in some embodiments, the first limiting portion is a limiting post 11 extending from one end of the light guide 1, and the light guide PCB 3 is provided with a first positioning hole 31 corresponding to the limiting post 11. Specifically, the number of limiting posts 11 is set to two or more. During installation, the first positioning hole 31 on the light guide PCB 3 is plugged into the limiting post 11, so that the limiting post 11 can limit the light guide PCB 3 in the first and second directions, so that the light guide PCB 3 can only slide along the direction of the limiting post 11. At the same time, in conjunction with the second limiting portion of the PCB board 5, the light guide PCB 3 can be limited in the third direction, so that the light guide PCB 3 cannot slide in the direction of the limiting post 11, thereby fixing the light guide PCB 3. It can be understood that the first direction and the second direction are two directions perpendicular to the extension direction of the limiting post 11, and the third direction is the extension direction of the limiting post 11.
[0024] like Figure 1 and 2As shown, to prevent heat accumulation when the light guide PCB 3 emits light, in some embodiments, a heat sink 4 is provided on one side of the light guide PCB 3. The heat sink 4 is provided with second positioning holes 42 corresponding to the limiting posts 11. The heat sink 4 is a sheet-like structure that fits snugly against the light guide PCB 3. Heat sink 4 can quickly dissipate heat from the light guide PCB 3. The positioning of the heat sink 4 is similar to that of the light guide PCB 3, and no additional positioning structure is required.
[0025] like Figure 1 and 2 As shown, specifically, in some embodiments, the PCB 5 is perpendicular to the light guide PCB 3. A notch 51 is provided at one end of the PCB 5 near the light guide PCB 3. The notch 51 forms the second limit portion, and the light guide PCB 3 is located within the notch 51. The light guide PCB 3 is inserted into the notch 51, and thus cannot move in the third direction.
[0026] like Figure 2 As shown, to facilitate installation of the PCB board 5, in some embodiments, the bracket 2 is provided with a positioning post 22 and a stud 23. The PCB board 5 is provided with a third positioning hole 52 that matches the positioning post 22, and a fixing hole 53 that corresponds to the stud 23. When installing the PCB board 5, the third positioning hole 52 can be aligned with the positioning post 22 for preliminary positioning, and then the PCB board 5 can be locked to the bracket 2 with the screw 6. This facilitates installation and has a simple structure.
[0027] In some embodiments, a heat sink 4 is further provided on one side of the light guide PCB 3 , and the heat sink 4 is located in the gap 51 .
[0028] like Figure 3As shown, in order to enable the PCB board 5 to better limit and fix the light guide PCB 3 and the heat sink 4, in some embodiments, a protruding rib 41 is provided on the side of the heat sink 4 opposite to the light guide PCB 3. The rib 41 includes a guide portion 411 and a platform portion 412. The platform portion 412 is a planar structure and is provided in the middle of the rib 41. The guide portion 411 is an inclined surface and connects the surface of the heat sink 4 and the platform portion 412. During installation, align the notch 51 of the PCB board 5 with the PCB board 5 and the heat sink 4, and press the PCB board 5 downward to insert the light guide PCB 3 and the heat sink 4 into the notch 51. During this process, a side wall of the notch 51 contacts the guide portion 411 of the rib 41. The inclined guide portion 411 enables the light guide PCB 3 and the heat sink 4 to smoothly enter the notch 51. At the same time, the rib 41 squeezes the heat sink 4 and the light guide PCB 3, causing them to slide and press along the limiting column 11 toward the main body of the light guide 1 until the side wall of the notch 51 contacts the platform portion 412, thereby tightly restricting and pressing the light guide PCB 3 and the heat sink 4 on the limiting column 11. Figure 1 As shown. Simple structure and stable installation.
[0029] like Figures 1 to 3 As shown, to prevent interference between the light guide PCB 3 and heat sink 4 and the PCB 5, in some embodiments, the heat sink 4 and the light guide PCB 3 are provided with a clearance portion, which is located at the same height as the rib 41. After the light guide PCB 3 and heat sink 4 are inserted into the notch 51 of the PCB 5, one end of the PCB 5 falls into the clearance portion, preventing interference between them.
[0030] During installation, the light guide 1 is mounted on the bracket 2, and the first positioning hole 31 of the light guide PCB 3 and the second positioning hole 42 of the heat sink 4 are sleeved on the limiting post 11 of the light guide 1. The PCB board 5 is then sleeved on the positioning post 22 of the bracket 2 through the third positioning hole 52 for preliminary positioning. The notch 51 of the PCB board 5 is aligned with the heat sink 4 and the light guide PCB 3. The PCB board 5 is continuously pressed until the PCB board 5 and the heat sink 4 are pressed against the limiting post 11. Finally, screws 6 are passed through the fixing holes 53 and the studs 23 on the bracket 2 to lock the PCB board 5. The assembly is complete.
[0031] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of this application.
