The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0032] See also Figure 1-Figure 5 , which is a schematic diagram of a lamp structure for fixing a light guide bar provided in an embodiment of the utility model, the lamp structure for fixing a light guide bar comprises a mounting bracket 100, a light guide bar assembly 200 disposed on the mounting bracket 100, and a light source component 300 disposed at one end of the light guide bar assembly 200, wherein:

[0033] In order to provide support for the light guide bar assembly 200, the mounting bracket 100 includes a bracket body 110 and a receiving groove 120 that is recessed along the length direction of the bracket body 110. Due to design requirements, the bracket body 110 is bent, so the receiving groove 120 is also bent, and the bracket body 110 is divided into a first bent portion 111 and a second bent portion 112, the first bent portion 111 and the second bent portion 112 are connected by an arched platform 113, and the receiving groove 120 is provided on the first bent portion 111.

[0034] Furthermore, a first guide hole 121 and a second guide hole 122 are respectively provided at both ends of the receiving groove 120. The first guide holes 121 are each provided at one end of the receiving groove 120 close to the arched platform 113. One end of the light guide bar assembly 200 passes through the first guide hole 121 into the receiving groove 120 until it is flush with the second guide hole 122. At this time, the other end of the light guide bar assembly 200 is just placed on the arched platform 113.

[0035] In order to install the light guide bar assembly 200, a limiting rib 130 is provided on one side of the first guide hole 121, so that when the light guide bar assembly 200 is inserted into the receiving groove 120 and one end thereof is flush with the second guide hole 122, the limiting rib 130 is used to abut against the other end of the light guide bar assembly 200 to prevent it from passing out of the receiving groove 120. At the same time, a connecting column 140 for connecting the light guide bar assembly 200 is also provided on the side of the limiting rib 130 away from the receiving groove 120. When the end of the light guide bar assembly 200 close to the second curved portion 112 is placed on the arched platform 113, the light guide bar assembly 200 is connected to the arched platform 113 through the fastener to complete the installation of the light guide bar assembly 200. The design of the receiving groove 120 can limit the movement of the light guide bar assembly 200 in the up, down, front and back directions, and the installation and connection of the light guide 210 can be completed under very limited space conditions. The assembly method is simple, and there is no need to lock too many screws, which reduces assembly time and saves labor costs.

[0036] Furthermore, the light guide bar assembly 200 includes a light guide 210, a fixing block 220, and a connecting plate 230 for connecting the light guide 210 and the fixing block 220. The light guide 210 and the fixing block 220 are both arranged on one side of the connecting plate 230 close to the receiving groove 120. In order to enhance the fit of the light guide 210, the shape of the receiving groove 120 is configured to conform to the shape of the light guide 210, so that when the light guide 210 is inserted into the receiving groove 120, it has a multi-directional restriction effect on the light guide 210, preventing it from moving, thereby enhancing the adaptability. At the same time, under the premise of the stable connection of the light guide 210, the generation of bright spot defects in the middle area of ​​the light guide 210 can be avoided, thereby avoiding the problem of luminous defects.

[0037] In order to connect the light guide 210 and the bracket body 110, a side of the fixing block 220 close to the bracket body 110 is recessed to form a clearance groove 221, and a connection hole 222 connected to the clearance groove 221 is also provided on the fixing block 220. When the fixing block 220 is placed on the arched platform 113, the connecting column 140 is just inserted into the clearance groove 221 and aligned with the connecting hole 222. A fastener is used to pass through the connecting hole 222 to connect with the connecting column 140. The fastener used in this embodiment is a bolt, which is screwed with the connecting column 140 to connect the fixing block 220 to the bracket body 110. This assembly method is simple, does not require locking too many screws, reduces assembly time, and saves labor costs.

[0038] It is worth emphasizing that when the fixing block 220 is connected to the connecting column 140 , the end thereof away from the connecting plate 230 abuts against the limiting rib 130 , thereby improving the stability of the connection between the light guide bar assembly 200 and the bracket body 110 .

[0039] Two limiting posts 231 extend from one side of the connecting plate 230 away from the fixing block 220 and the light guide 210. The two limiting posts 231 are arranged at opposite corners of the connecting plate 230. Meanwhile, abutting posts 232 are arranged at the other opposite corners of the connecting plate 230. Accordingly, rivet holes 310 corresponding in number and position to the limiting posts 231 are arranged on the light source component 300. When the limiting posts 231 are inserted into the rivet holes 310, the abutting posts 232 abut against the side plate of the light source component 300 to prevent the components arranged on the light source component 300 from being squeezed and damaged. At this time, the limiting posts 231 and the rivet holes 310 are connected by heat riveting to connect the light source component 300 with the light guide bar assembly 200.

[0040] In addition, a number of extended or recessed parts are injection-molded on the bracket body 110 to block unnecessary light. There is no need to add other light-shielding parts to achieve the ideal light-emitting effect, thus saving development costs.

[0041] In summary, according to a lamp structure for fixing a light guide bar proposed by the utility model, by inserting the light guide bar assembly into the receiving groove, the light guide bar assembly is avoided from being arranged on the bracket body to increase the volume of the lamp body, and the other end of the light guide bar assembly is connected to the bracket body to complete the installation of the light guide bar assembly under limited space conditions. Specifically, the mounting bracket includes a bracket body and a receiving groove arranged along the length direction of the bracket body. The light guide bar assembly is inserted into the receiving groove, one end of which is flush with one end of the receiving groove, and the other end is connected to the bracket body by a fastener to complete the installation of the light guide bar assembly under limited space conditions, while limiting the movement of the light guide bar assembly. The light source part is arranged at one end of the light guide bar assembly away from the receiving groove for lighting. The structure of the utility model completes the installation of the light guide bar assembly under very limited space conditions, the assembly method is simple, there is no need to lock too many screws, the assembly time is reduced, the labor cost is saved, and the generation of bright spot defects in the middle area of ​​the light guide is avoided under the premise of ensuring the stable connection of the light guide bar assembly. At the same time, the existing parts can be completely used to block the unnecessary light, without adding other shading parts, saving development costs.
