Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a novel vehicle lamp lens module. Background Technique

[0002] In the patent document CN202322257781.X, "a structure for improving the uniformity of vehicle lamp light" is disclosed, which includes a condenser, an optical structure, and a light-emitting structure. The optical structure is at least one layer, and the optical structure is formed by overlapping multiple diamond structures in sequence. One diagonal of the multiple diamond structures is parallel, and the other diagonal of the multiple diamond structures is perpendicular to the condenser. An LED is provided at the light-condensing end of the condenser. The light emitted by the LED is projected onto the end face of the diamond structure through the condenser, and then projected onto the light-emitting structure through the opposite side of the diamond structure, and the light is emitted from the light-emitting structure. The structure for improving the uniformity of vehicle lamp light of the utility model rationally utilizes the light effect, improves the lighting dark area, saves the usage amount of LEDs, and reduces the cost.

[0003] The lens module with three rows of diamond structures in this patent can improve the uniformity of light divergence. However, the distance between the lens and the light source remains unchanged, and the adjustment of the light uniformity cannot be achieved, so it cannot adapt to different driving environments, which has certain limitations. For this reason, we propose a novel vehicle lamp lens module to solve the problems raised in the above background technique. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a novel vehicle lamp lens module to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A novel vehicle lamp lens module includes a chassis, a light source, an adjustment mechanism, and a diffusing lens plate. The light source is fixedly installed at the center position on the top of the chassis. The number of the adjustment mechanisms is two and they are symmetrically installed on the chassis. The number of the diffusing lens plates is two and they are respectively fixedly connected to the moving ends of the two adjustment mechanisms;

[0006] The adjusting mechanism includes a vertical block fixedly connected to the top of the chassis. An adjusting cavity is formed inside the vertical block, and a transmission cavity is formed below the adjusting cavity inside the vertical block. A stepping motor is fixedly installed on the left side of the vertical block, and the output shaft of the stepping motor penetrates into the transmission cavity and is fixedly connected to a driving bevel gear. A rolling bearing is fixedly installed at the top of the inner wall of the adjusting cavity, and a screw rod is rotatably connected inside the rolling bearing. The bottom end of the screw rod penetrates into the transmission cavity and is fixedly connected to a driven bevel gear adapted to the driving bevel gear. A lifting block is threadedly connected to the surface of the screw rod located in the adjusting cavity. A through groove communicating with the adjusting cavity is formed on the right side of the vertical block, and the right side of the lifting block penetrates outside the through groove and is fixedly connected to one end of the diffusing lens plate. A guiding sliding groove adapted to the diffusing lens plate is formed on the right side of the lifting block.

[0007] Further, dust-proof folding curtains are fixedly connected to both the top and bottom of the inner wall of the through groove, and one side of the dust-proof folding curtain close to the lifting block is fixedly connected thereto.

[0008] Further, positioning plates are symmetrically installed on the chassis, and screw holes are formed in the positioning plates.

[0009] Further, the opposite sides of the two diffusing lens plates are in contact with each other.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] The present utility model uses the positioning plates to realize the installation and fixation of the chassis. After the light source emits light, it is evenly diffused by the diffusing lens plate. When the position needs to be adjusted, the stepping motor can be controlled to start, so that its output shaft drives the driving bevel gear to rotate. The driven bevel gear meshed therewith can drive the screw rod to rotate under the connection of the rolling bearing. Since one end of the diffusing lens plate is limited by cooperating with the guiding sliding groove on another vertical block, the lifting block threadedly connected to the screw rod will drive the diffusing lens plate to move vertically, thereby realizing the adjustment of the light uniformity. This new type of vehicle lamp lens module has a reasonable structural design and is convenient to use. It can effectively improve the uniformity of light diffusion. Moreover, the lens module adopts a movable design, and the uniformity of light diffusion can also be adjusted, so as to adapt to different driving environments, reduce limitations, and has a high use effect.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-4 , a new type of headlight lens module, including a chassis 1, a light source 2, an adjustment mechanism 3 and a light-diffusing lens plate 4. The light source 2 is fixedly installed at the center position on the top of the chassis 1. The number of adjustment mechanisms 3 is two and they are symmetrically installed on the chassis 1. The number of light-diffusing lens plates 4 is two and they are respectively fixedly connected to the mobile ends of the two adjustment mechanisms 3. The shape and structure of the light-diffusing lens plate 4 have been shown in the accompanying drawings and are mature prior arts, so they will not be described in detail here.

[0019] Specifically, the adjustment mechanism 3 includes a vertical block 31. The vertical block 31 is fixedly connected to the top of the chassis 1. An adjustment cavity 32 is opened inside the vertical block 31. A transmission cavity 33 is opened below the adjustment cavity 32 inside the vertical block 31. A stepper motor 34 is fixedly installed on the left side of the vertical block 31. The output shaft of the stepper motor 34 penetrates into the transmission cavity 33 and is fixedly connected to a driving bevel gear 35. A rolling bearing 36 is fixedly installed at the top of the inner wall of the adjustment cavity 32. A screw rod 37 is rotatably connected inside the rolling bearing 36. The bottom end of the screw rod 37 penetrates into the transmission cavity 33 and is fixedly connected to a driven bevel gear 38 adapted to the driving bevel gear 35. A lifting block 39 is threadedly connected to the surface of the screw rod 37 located in the adjustment cavity 32. A through slot 310 communicating with the adjustment cavity 32 is opened on the right side of the vertical block 31. The right side of the lifting block 39 penetrates outside the through slot 310 and is fixedly connected to one end of the light-diffusing lens plate 4. A guiding sliding slot 311 adapted to the light-diffusing lens plate 4 is opened on the right side of the lifting block 39.

[0020] Specifically, dust-proof folding curtains 312 are fixedly connected to both the top and bottom of the inner wall of the through groove 310. One side of the dust-proof folding curtain 312 close to the lifting block 39 is fixedly connected thereto. The dust-proof folding curtain 312 can prevent external dust, sundries, etc. from entering the adjustment cavity 32 through the through groove 310.

[0021] Specifically, positioning plates 5 are symmetrically installed on the chassis 1. Screw holes are provided on the positioning plates 5. The positioning plates 5 can cooperate with bolts to fix the chassis 1 and the lens module above.

[0022] Specifically, the opposite sides of the two astigmatic lens plates 4 are in contact with each other.

[0023] The novel vehicle headlight lens module has a reasonable structural design and is convenient to use. It can effectively improve the uniformity of light divergence. Moreover, the lens module adopts a movable design, and the uniformity of light divergence can also be adjusted, so as to adapt to different driving environments, reduce limitations, and has a high use effect.

[0024] During use, the chassis 1 is installed and fixed by using the positioning plates 5. After the light source 2 emits light, it is evenly diverged by the astigmatic lens plates 4. When its position needs to be adjusted, the stepper motor 34 can be controlled to start, so that its output shaft drives the driving bevel gear 35 to rotate. The driven bevel gear 38 engaged therewith can drive the screw rod 37 to rotate under the connection of the rolling bearing 36. Since one end of the astigmatic lens plate 4 is limited by cooperating with the guiding chute 311 on another upright block 31, the lifting block 39 threadedly connected to the screw rod 37 will drive the astigmatic lens plate 4 to move vertically, thereby realizing the adjustment of the light uniformity.
