[0002] Automotive instrument lamps, also known as automotive instrument ambient lights, can improve the safety of night driving, enhance the technological sense and modernity of the vehicle, and can relieve the fatigue of the driver, relax the mood, make the in-vehicle life more ritualistic, and create a relaxed and pleasant atmosphere. The automotive instrument lamp assembly of the related technology includes a bracket, a light-emitting element, a wire harness assembly, and a light guide bar. The light guide bar is generally a cylindrical light guide bar made of light guide materials such as PMMA, PC, PS, etc.; the light-emitting element includes a housing connected to the bracket and a circuit board connected inside the housing. The circuit board is integrated with an LED lamp, and the LED lamp is located at one end of the light guide bar. The light emitted by the LED is guided by the light guide bar, so that the entire light guide bar emits light, presenting a lighting effect around the automotive instrument.

[0003] The automotive instrument lamp assembly of the above related technology has the following defects in actual use: The bracket of the automotive instrument lamp assembly is generally of an irregular shape, which is adapted to the shape of the automotive center console, such as being set with an L-shaped cross-section; the light-emitting element is connected to the bottom of the bracket, so that the light guide bar has a first light guide portion extending along the side wall of the bracket and a second light guide portion extending along the longitudinal direction of the bracket. There is a bent corner portion between the first light guide portion and the second light guide portion; when the light emitted by the light-emitting element is transmitted from the first light guide portion to the second light guide portion, it has to pass through the corner portion between the first light guide portion and the second light guide portion. However, when the light passes through the corner portion, due to the bending of the light guide bar at the corner portion, the light forms a concentration at the corner portion, and under the blocking effect of the bracket, a concentrated bright spot is generated at the corner portion of the light guide bar, that is, the brightness at the corner portion is much higher than the brightness of the first light guide portion and the second light guide portion; moreover, a relatively bright light spot is generated on the automotive instrument panel, thus affecting the ambient lighting effect of the automotive instrument. Summary of the Utility Model

[0004] The technical problem to be solved by this application is to overcome the defects of the above related technologies and provide an automotive instrument lamp assembly that can avoid or reduce the defect of concentrated bright spots generated at the corner portion of the light guide bar.

[0021] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See Figures 1 to 4 As shown in the figure; the embodiments of the present application disclose an automotive instrument lamp assembly, the structure of which includes a bracket 1 and a light-emitting element 2 and a light guide bar 4 connected to the bracket 1. The bracket 1 is connected to the automotive center control skeleton. The bracket 1 includes a bottom plate 100 and a side plate 101 located on one side of the bottom plate 100. The bottom plate 100 and the side plate 101 are an integrally injection-molded structure. The bottom plate 100 is provided with a first mounting portion 102 for fixing the light guide bar 4, and the side plate 101 is provided with a second mounting portion 103 for fixing the light guide bar 4 along the horizontal direction or an approximately horizontal direction; wherein, the first mounting portion 102 is two spaced-apart mounting plates 104 connected to the bottom plate 100, and a first mounting portion 102 is formed between the two mounting plates 104. A limiting block 105 for preventing the light guide bar 4 from falling off is provided on the inner wall of the mounting plate 104; further, the second mounting portion 103 is a concave card slot 106 provided on the back of the side plate 101, and a clamping block 107 for preventing the second light guide portion 401 of the light guide bar 4 from falling off is provided on the card slot 106.

[0023] In this embodiment, the light-emitting element 2 is connected to the bracket 1, and the light-emitting element 2 includes a housing 200 and a circuit board 201 connected inside the housing 200. An LED lamp is electrically connected to the circuit board 201. The circuit board 201 is connected to the automotive driving computer to obtain power through a wire harness assembly 3. The outer end of the wire harness assembly 3 is connected with a plug 300 that is electrically connected to the automotive driving computer or the automotive power supply line.

[0024] It is not difficult to understand that in this embodiment, as Figure 4 shown, one side of the bottom plate 100 is provided with a mounting position. The housing 200 of the light-emitting element 2 is installed on the bottom plate 100 through screws. The housing 200 has a rear cover 203, and a hollow annular convex wall 202 is provided on the housing 200. The LED lamp on the circuit board 201 is located at the inner end of the annular convex wall 202. The end of the light guide bar 4 is tightly fitted inside the annular convex wall 202 and is arranged corresponding to the LED lamp.

[0025] Further, in the present embodiment, the light guide bar 4 is connected to the bracket 1. One end of the light guide bar 4 is disposed opposite to the LED lamp on the circuit board 201, and is used to conduct the light emitted by the LED lamp. The light guide bar 4 is arranged along the direction around the bracket 1, that is, a part of the light guide bar 4 is installed on the first installation portion 102 of the bottom plate 100, and another part of the light guide bar 4 is installed on the second installation portion 103 of the side plate 101. The height of the second installation portion 103 is higher than that of the first installation portion 102; therefore, after the light guide bar 4 passes through the first installation portion 102 and reaches the second installation portion 103, the light guide bar 4 makes a turn between the two; that is, the light guide bar 4 has a first light guide portion 400 extending along the height direction of the bracket 1 and a second light guide portion 401 extending along the horizontal direction of the bracket 1, and there is a curved turning portion 402 between the first light guide portion 400 and the second light guide portion 401.

[0026] It can be understood that the light guide bar 4 is bent at the turning portion 402, and the light is concentrated at the turning portion 402. Under the blocking or reflecting action of the bracket 1, the light at the turning portion 402 of the light guide bar 4 is not easily diffused out. Therefore, a concentrated light bright spot will be generated at the turning portion 402 of the light guide bar 4, that is, the brightness at the turning portion 402 is much higher than that of the first light guide portion 400 and the second light guide portion 401, which will generate a brighter light spot on the vehicle instrument panel, thus affecting the atmosphere lighting effect of the vehicle instrument. To solve the above defect that the light guide bar 4 generates a concentrated light bright spot at the turning portion 402, in the embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, a notch 109 is provided at the position of the bracket 1 corresponding to the turning portion 402 of the light guide bar 4. The setting of the notch 109 allows a part of the light at the turning portion 402 of the light guide bar 4 to diffuse outward to avoid the light being concentrated at the turning portion 402 to generate a bright spot. Therefore, in the present embodiment, the vehicle instrument lamp assembly is provided with a notch 109 at the position of the bracket 1 corresponding to the turning portion 402. The setting of the notch 109 increases the distance between the turning portion 402 and the bracket 1. Therefore, a part of the light at the turning portion 402 of the light guide bar 4 can be quickly diffused outward to avoid the light being concentrated at the turning portion 402 to generate a bright spot. Therefore, the vehicle instrument lamp assembly can avoid or reduce the defect of the concentrated bright spot generated at the turning portion 402 of the light guide bar 4, and make the atmosphere lighting effect of the vehicle instrument better.

[0027] Specifically, in this embodiment, a baffle 108 integrally formed with the side plate 101 is provided at the top of the second installation part 103, and a notch 109 is provided at one end of the baffle 108 close to the corner part 402. The inner wall of the notch 109 is set as an inclined surface with a lower inner end and a higher outer end. When light passes through the corner part 402, the light gathered at the corner part 402 can be diffused outward through the notch 109. Therefore, after a part of the light is diffused at the corner part 402, the high-brightness light spot at the corner part 402 becomes dim, thereby avoiding or reducing the defect of concentrated bright spots generated at the corner part 402 of the light guide bar 4.

[0028] In some embodiments, the surface of the baffle 108 of the bracket 1 is provided with leather texture. The setting of the leather texture makes the light emitted by the light guide bar 4 softer.
