Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a light-guiding strip type high-mounted brake lamp with an integrated camera. Background Art

[0002] The high-mounted brake light is a brake warning light on a car, typically used in conjunction with the brake lights. When the driver presses the brake pedal, the left and right brake lights, located lower on either side of the vehicle, illuminate, and the high-mounted brake light, located at the top of the rear, illuminates simultaneously, alerting vehicles behind them to driving safety from different heights.

[0003] Existing high-mounted stop lights (HSLs) have relatively simple structures and functions, failing to meet the increasingly rapid upgrade needs of OEMs. Our company has previously developed a series of HSLs with varying shapes and structures, including CN117267656A, CN219264044U, CN216644090U, CN213237383U, CN213237384U, and CN210454617U. Building on these achievements, and to meet the functional requirements of new energy vehicles, we have developed a light-guided HSL with an integrated camera. Utility Model Content

[0007] Furthermore, the light guide bar includes a straight portion, an arc-shaped bending portion, and a flat connecting portion 15 . The arc-shaped bending portion is located between the straight portion and the flat connecting portion 15 , and the straight portion is close to the camera 3 .

[0008] Furthermore, the LED circuit board 16 is fixedly connected to the flat plate connecting portion 15 , and a transparent light inlet point is provided on the flat plate of the flat plate connecting portion 15 , and the light inlet point is directly facing the LED lamp beads on the LED circuit board 16 .

[0009] Furthermore, a pattern 14 is provided on the light-emitting surface of the light guide strip, and the pattern includes a serrated pattern, a concave-convex pattern, and a wavy pattern.

[0010] Furthermore, two light-emitting surfaces 13 are symmetrically provided on the light distribution mirror 8 , and the length of the light-emitting surface 13 is smaller than the length of the light guide bar.

[0011] This new design utilizes a bilaterally symmetrical split-type light guide structure, sandwiching the camera between these two sets of light guides. This design not only offers a simple and aesthetically pleasing design, but also integrates the functions of the high-mounted brake light and rearview camera, meeting the requirements of OEMs. This high-mounted brake light boasts numerous advantages, including a simple structure, rich functionality, and a stylish and novel appearance. It is expected to achieve significant economic benefits upon the launch of new vehicles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to enable ordinary technicians in this field to fully understand the technical solutions and beneficial effects of the utility model, further description is given below in conjunction with specific embodiments and drawings.

[0018] like Figure 4The high-mounted brake light shown is in the shape of a long and thin strip. A camera 3 is arranged in the middle of the lamp body. The two sides of the camera are the light-emitting surfaces 13 of the high-mounted brake light. When it is lit, it can serve as a brake warning and provide lighting for the camera.

[0019] The structure of the high-mounted brake light is as follows: Figure 1-2 As shown, the lamp primarily comprises a base 1, a wiring harness assembly 2, a camera 3, a camera mount 4, a left and right light guide assembly, a photometric lens 8, and an LED circuit board 16. The base 1 is injection-molded from opaque plastic and features a groove in its center. The camera mount 4 is first secured within this groove, and then the camera 3 is secured within the mount 4, completing the camera assembly. The left and right light guide assemblies, along with the LED circuit board 16, are then symmetrically secured to the base 1 using multiple screws 12. The wires of the wiring harness assembly 2 are then connected to the camera 3, the left and right light guide assemblies, and the LED circuit board 16, respectively. Finally, the photometric lens 8 is welded to the base 1, completing the package of the entire lamp.

[0020] The left light guide bar assembly and the right light guide bar assembly have the same structure and are symmetrical. The following description will take the right light guide bar assembly as an example. The right light guide bar assembly includes a right light guide bar bracket B5, a right light guide bar bracket A6, and a right light guide bar 7. The right light guide bar bracket B5 and the right light guide bar bracket A6 are fixed to the base 1 in a vertically parallel manner by means of buckles, screws 12, etc. (as shown in FIG. Figure 2 As shown), a groove is reserved between the two, and the light guide bar 7 is fixed in the groove.

[0021] The structure of the light guide bar 7 is as follows Figure 3 As shown, it includes a straight portion (approximately a straight line) close to the camera, an arc-shaped bending portion in the middle, and a flat connecting portion 15 on the outermost side. Although divided into three parts, the light guide bar is actually made of transparent plastic such as PC and is integrally injection-molded. This is mainly because the refractive index of PC is higher than that of air, and total internal reflection occurs when light propagates in the light guide bar made of PC. A pattern 14 for reflecting and scattering light is provided on the outer surface of the straight portion of the light guide bar 7, which is used to obtain a uniform lighting effect. The flat connecting portion 15 of the light guide bar 7 is fixedly connected to the LED circuit board 16 in a face-to-face manner, and a transparent light inlet point is provided on the flat connecting portion 15 at a position facing the LED lamp bead. When the LED is powered on and emits light, the light enters the light guide bar through the light inlet point and is emitted outward, ensuring that no light leakage occurs. In addition, the lengths of the leftmost and rightmost ends of the luminous surface 13 on the light distribution mirror 8 are shorter, ensuring that the installation point of the light guide bar will not appear in the visible area, so there will be no bright spots or black areas, which improves the lighting effect and aesthetics of the entire lamp.
