Description

[0002] Corner lights provide auxiliary lighting for the corners of the road in front of the vehicle or for the side of the vehicle. When the road lighting conditions are insufficient, corner lights play a certain auxiliary lighting role and provide a guarantee for driving safety.

[0003] At present, there are many common LED lenses commonly used in lens modules for automobile headlights, but the functions are single.

The lens bracket 150 is cylindrical and fixedly sleeved on the outside of the corner lamp thick wall inner lens 130 and the high beam inner lens 140.

[0046] The main lens 160 is a glass lens, which is fixedly mounted on the front end of the lens bracket 150 (the end facing the front of the car). The main lens 160 is divided into a first part 161 and a second part 162. The first part 161 is located on the upper side corresponding to the position of the corner light circuit board 110, and the second part 162 is located on the lower side corresponding to the position of the high beam light circuit board 120.

[0047] The heat sink 170 is fixedly connected to the back sides of the corner light circuit board 110 and the high beam light circuit board 120 , and the heat sink 170 is fixedly connected to the rear end of the lens bracket 150 .

[0048] The auxiliary bracket 180 is arranged in the lens bracket 150 and is located on the opposite side of the corner lamp thick-walled inner lens 130, that is, the auxiliary bracket 180 is arranged on the same side as the high beam inner lens 140; the auxiliary bracket 180 is a U-shaped bracket, which is arranged around the outer side of the high beam inner lens 140 and does not block the high beam inner lens 140.

Among them, the length of the first side 141c of the main body 141 close to the inner side of the vehicle body is greater than the length of the second side 141d close to the outer side of the vehicle body, so that the arc surface end 141b of the main body 141 is inclined toward the outer side of the vehicle body.

[0052] A plurality of total reflection lenses 142 are mounted on the plane end 141a of the thick-walled inner lens body 141 of the corner lamp. The through hole 143 is located between the plane end 141a and the curved surface end 141b of the thick-walled inner lens body 141 of the corner lamp, and penetrates the thickness direction of the body 141, that is, the through hole 143 is opened in the vertical direction; the end face of the through hole 143 and the cross-sectional contour line in the horizontal direction are both shuttle-shaped and have the same size, and the shuttle shape (in the length direction) is arranged along the width direction of the body 141. The two curved surfaces in the through hole 143 near the plane end 141a and the curved surface end 141b respectively constitute optical structures.

[0053] As a preferred embodiment, the contour line of the arc surface end 141b along the horizontal cross section from the first side 141c to the second side 141d of the main body 141 includes: a first arc 141ba, a second arc 141bb, a third arc 141bc and a straight line segment 141bd.

The contour lines of each (vertical) cross section of the arc surface end 141 b along the length direction of the main body 141 are all vertical straight line segments.

[0054] As a preferred embodiment, the contour line of the end face (cross-section contour line in the horizontal direction) of the through hole 143 is composed of two arcs arranged opposite to each other on the concave side, namely, the arc 143a close to the plane end 141a and the arc 143b close to the arc surface end 141b. The curvature radius of the arc 143a and the arc 143b are both 90-110 mm; the arc lengths are both 50-70 mm.

[0055] As a further preference, the number of the total reflection lenses 142 is at least 3. In this embodiment, the number of the total reflection lenses 142 is 4.

[0056] The working principle of the high beam lens module with optical thick-wall corner lamp function provided by the present invention is as follows: the light emitted by the corner lamp (LED) light source is completely absorbed by multiple total reflection lenses 142 and reflected into the thick-wall inner lens 130 of the corner lamp, and the light passes through the arc surface where the arc 143a is located, the arc surface where the arc 143b is located, and the arc surface end 141b in the thick-wall inner lens 130 in turn, so that the light is refracted multiple times and scattered out, and finally refracted and scattered out through the first part 161 of the main lens 160, and finally illuminated on the ground 30° to 60° to the left (right) outside of the front of the car that needs to be lit, so as to achieve the corner lamp lighting requirements. The light emitted by the high beam lamp (LED) light source is refracted by the high beam lamp inner lens 140, and then refracted and scattered out through the second part 162 of the main lens 160, so as to achieve the high and low beam functions. The material cost of the present invention is low, the manufacturing cost is low, the assembly is simple, the corner lamp does not need to occupy a separate space, and there is no need to add other installation structures or separate structures. The function is simple and easy to implement. It can be integrated with the high beam inside the lens to achieve overall lighting, which can greatly meet the styling requirements of automobile headlights.

[0057] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
