Technical Field

[0001] The invention relates to the technical field of vehicle lamp adjustment, and in particular to an LED double high-beam lens assembly. Background Art

[0002] With the development of automobile technology and the improvement of road conditions, the requirements for the lighting distance and brightness of automobile headlights are getting higher and higher. The lighting distance of modern automobile headlights has reached 200-400 meters to ensure that drivers can clearly see obstacles in the distance when driving at high speed, thereby improving driving safety.

[0003] In order to improve the visibility of distant scene lighting, it is necessary to increase the light intensity of the high beam. In the prior art, two high beam modules are generally used to enhance the light intensity of the high beam to improve the visibility of distant scenes. However, there are some defects in the existing two high beam modules, such as the two high beam modules cannot be adjusted independently, and the two high beam modules will produce two light spots. However, the driver's attention is often focused on one point. The existence of two light spots is inconsistent with the driver's observation habits. Long-term observation will make the driver feel tired, which may cause the driver to fail to find obstacles in distant scenes in time, and in some cases may cause traffic accidents. Therefore, how to increase the light intensity while eliminating the interference of this double light spot, so that the lighting of distant scenes by car headlights is more in line with the driver's observation habits, and improve the driver's flexibility in responding to distant obstacles so as to make various emergency responses in time and reduce the occurrence of traffic accidents, is a technical problem that needs to be solved to improve the performance of car headlights.

[0016] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0017] 1. The LED dual high-beam lens group provided by the present invention has a universal seat fixedly connected to the second bracket, and the second bracket fixedly connected to the first high-beam lens group, so the first high-beam lens group, the universal seat and the second bracket are fixedly connected as a whole. When the ball head adjustment screw is rotated, the ball head adjustment screw will move axially. Due to the buckling of the ball socket of the universal seat and the ball head of the ball head adjustment screw, the axial movement of the ball head adjustment screw will cause the ball head to slide and rub in the ball socket, so that the universal seat will deflect. The deflection of the universal seat will drive the second bracket and the first high-beam lens group to deflect as a whole. The deflection of the first high-beam lens group will cause the change of the projection direction and range of the light. At the same time, due to the gap between the second bracket and the first bracket, that is, the deflection of the second bracket is interfered, so the deflection of the second bracket can only be deflected in the gap space, and the first high-beam lens group can achieve an adjustment angle of ±2°. The second high-beam lens group is fixedly connected to the first bracket and has nothing to do with the deflection of the second bracket, so the projection direction and range of the second high-beam lens group will not change with the first high-beam lens group, realizing independent dimming of the first high-beam lens group and the second high-beam lens group, which is more convenient. In addition, taking the aiming of the second high-beam lens group as a reference, if the first high-beam lens group is not dimmed, it may cause the illumination of the first high-beam lens group and the second high-beam lens group to be parallel, and two light spots appear. At this time, the ball head adjustment screw can be fine-tuned to adjust the first high-beam lens group to a suitable angle to coincide with the aiming reference of the second high-beam lens group, so that while enhancing the visibility of the distant scene lighting, the interference of the double light spots is eliminated, so that the illumination of the distant scene by the car headlights is more in line with the driver's observation habits, and the driver's flexibility in responding to distant obstacles is improved, so that various emergency responses can be made in time, thereby reducing the occurrence of traffic accidents.

[0018] 2. The LED dual high-beam lens group provided by the present invention, after the second high-beam lens group is adjusted, that is, the aiming of the second high-beam lens group is determined, if the first high-beam lens group needs to be adjusted left and right, the first ball head adjustment screw can be rotated to fine-tune the axial movement of the first ball head adjustment screw, which will cause the first universal seat to deflect. At the same time, due to the sliding friction between the second universal seat and the ball head in the second ball head adjustment screw, and the sliding friction between the third universal seat and the ball head in the third ball head adjustment screw, the second bracket will drive the first high-beam lens group to deflect up and down with the straight line formed by the second ball head adjustment screw and the third ball head adjustment screw as the axis, so that the projection direction and range of the first high-beam lens group are changed, and overlap with the aiming of the second high-beam lens group, thereby increasing the high-beam light intensity and avoiding the interference of the double light spots of the first high-beam lens group and the second high-beam lens group. If it is necessary to adjust the first high-beam lens group forward and backward, the third ball head adjustment screw can be rotated to fine-tune the projection direction and range of the first high-beam lens group, and the axial movement of the third ball head adjustment screw will cause the third universal seat to deflect. At the same time, due to the sliding friction between the second universal seat and the ball head in the second ball head adjustment screw, and the sliding friction between the first universal seat and the ball head in the first ball head adjustment screw, the second bracket will drive the first high-beam lens group to deflect forward and backward with the straight line formed by the first ball head adjustment screw and the second ball head adjustment screw as the axis, so that the projection direction and range of the first high-beam lens group are changed, and overlap with the aiming of the second high-beam lens group.

DETAILED DESCRIPTION

[0024] The present invention provides an LED dual high-beam lens assembly, such as Figure 1-Figure 4As shown, it includes a first bracket 1 and a second bracket 2 with a gap, and the first bracket 1 is provided with a first high-beam lens group 3 and a second high-beam lens group 4 arranged in parallel from top to bottom. When the LED headlight needs to be dimmed, the projection direction and range of the light can be changed by adjusting the position or angle of the first high-beam lens group 3 or the second high-beam lens group 4, thereby achieving the adjustment of the high beam. The first bracket 1 is threadedly connected with three ball head adjustment screws. Specifically, the first bracket 1 is provided with a first bracket threaded hole 5, and each ball head adjustment screw also includes a threaded portion (not shown), which is threadedly connected in the first bracket threaded hole 5. The three ball head adjustment screws include a first ball head adjustment screw 6, a second ball head adjustment screw 7 and a third ball head adjustment screw 8. The first ball head adjustment screw 6 is located above the first high-beam lens group 3, and the second ball head adjustment screw 7 and the third ball head adjustment screw 8 are located between the first high-beam lens group 3 and the second high-beam lens group 4 and are in a straight line, so that the three ball head adjustment screws are L-shaped as a whole. The first high-beam lens group 3 passes through the first bracket 1 and the second bracket 2 and is fixedly connected to the second bracket 2. Specifically, the first bracket 1 is provided with a first through hole 9 and a second through hole 10, the second bracket 2 is provided with a third through hole 11, the first high-beam lens group 3 passes through the first through hole 9 and the third through hole 11, and the first high-beam lens group 3 is provided with a first high-beam lens group shoulder 12 so as to limit the first high-beam lens group 3. The first high-beam lens group shoulder 12 is provided with first connecting holes 13 at the four corners, the first through hole 9 on the first bracket 1 is provided with first bracket connecting holes 14 at the four corners of the edge, and the second bracket boss 15 is provided at the four corners of the edge of the third through hole 11 of the second bracket 2. The first connecting hole 13, the first bracket connecting hole 14 and the second bracket boss 15 correspond to and fit one by one, respectively, and the second bracket boss 15 is plugged into the first bracket connecting hole 14. A boss hole 16 is provided at the center of the boss of the first bracket, and the first connection hole 13 and the boss hole 16 are threadedly connected by screws, so that the first high-beam lens group 3 is fixedly connected to the second bracket 2. The second high-beam lens group 4 is fixedly connected to the first bracket 1. Specifically, the second high-beam lens group 4 passes through the second through hole 10, and the second high-beam lens group 4 is provided with a second high-beam lens group shoulder 17 to limit the second high-beam lens group 4. Second connection holes 18 are provided at the four corners of the second high-beam lens group shoulder 17, and first bracket receiving holes 19 are provided at the four corners of the edge of the second through hole 10 on the first bracket 1. The second connection hole 18 corresponds to and fits with the first bracket receiving hole 19 and is threadedly connected by screws, so that the second high-beam lens group 4 is fixedly connected to the first bracket 1.

[0025] Three universal seats are fixedly connected to one side of the second bracket 2 close to the first bracket 1, and the three universal seats correspond to the three ball head adjustment screws one by one. The three universal seats include a first universal seat 20, a second universal seat 21 and a third universal seat 22. The first ball head adjustment screw 6 is connected to the first universal seat 20, the second ball head adjustment screw 7 is connected to the second universal seat 21, and the third ball head adjustment screw 8 is connected to the third universal seat 22. The ball head 23 of the ball head adjustment screw is connected in the universal seat. The connection relationship between the first ball head adjustment screw 6 and the first universal seat 20 is described below by taking them as an example. Specifically, the first universal seat 20 is hollow as a whole and includes a connected ball socket 24, a wing 25 and a cylindrical portion 26. The side wall of the cylindrical portion 26 is provided with a clamping wing 27. The second bracket 2 is provided with a hollow boss 28 corresponding to the first universal seat 20. The inner wall of the boss 28 is provided with a convex edge 29. The cylindrical portion 26 is inserted into the boss 28 and the clamping wing 27 is clamped onto the convex edge 29 to achieve a fixed connection between the first universal seat 20 and the second bracket 2. In addition, the wing 25 is provided with a wing through hole 30, which corresponds to the reserved hole (not shown) on the second bracket 2 to be threadedly connected by a screw, further ensuring the fixed connection between the first universal seat 20 and the second bracket 2. The first ball head adjustment screw 6 includes a ball head 23, which abuts against the ball socket 24. A plurality of convex wings 31 are provided on the inner wall of the ball socket near the opening to limit the ball head 23 in the ball socket 24 so that the ball head 23 is fixed in the first universal seat 20.

[0026] Since the universal seat is fixedly connected to the second bracket 2, and the second bracket 2 is fixedly connected to the first high-beam lens group 3, the first high-beam lens group 3, the universal seat and the second bracket 2 are fixedly connected as a whole. When the ball head adjustment screw is rotated, the ball head adjustment screw will move axially. Due to the engagement between the ball socket 24 of the universal seat and the ball head 23 of the ball head adjustment screw, the axial movement of the ball head adjustment screw will cause the ball head 23 to slide and rub in the ball socket, so that the universal seat will deflect. The deflection of the universal seat will drive the second bracket 2 and the first high-beam lens group 3 to deflect as a whole. The deflection of the first high-beam lens group 3 will cause the change of the projection direction and range of the light. At the same time, since there is a gap between the second bracket 2 and the first bracket 1, that is, the deflection of the second bracket 2 is interfered, so the deflection of the second bracket 2 can only be deflected in the gap space, and the first high-beam lens group 3 can achieve an adjustment angle of ±2°. The second high-beam lens group 4 is fixedly connected to the first bracket 1 and has nothing to do with the deflection of the second bracket 2, so the projection direction and range of the second high-beam lens group 4 will not change with the first high-beam lens group 3, realizing the independent dimming of the first high-beam lens group 3 and the second high-beam lens group 4, which is more convenient. In addition, based on the aiming of the second high-beam lens group 4, if the first high-beam lens group 3 is not dimmed, it may cause the illumination of the first high-beam lens group 3 and the second high-beam lens group 4 to be parallel, and two light spots will appear. At this time, the ball head adjustment screw can be fine-tuned to adjust the first high-beam lens group 3 to a suitable angle to coincide with the aiming reference of the second high-beam lens group 4, so that while enhancing the visibility of the distant scene lighting, the interference of the double light spots is eliminated, so that the illumination of the distant scene by the car headlights is more in line with the driver's observation habits, and the driver's flexibility in responding to distant obstacles is improved, so that various emergency responses can be made in time, thereby reducing the occurrence of traffic accidents.

[0027] In addition, after the second high-beam lens group 4 is adjusted, that is, the aiming of the second high-beam lens group 4 is determined, if the first high-beam lens group 3 needs to be adjusted left and right, the first ball head adjustment screw 6 can be rotated to fine-tune the axial movement of the first ball head adjustment screw 6, which will cause the first universal seat 20 to deflect. At the same time, due to the sliding friction between the second universal seat 21 and the ball head 23 in the second ball head adjustment screw 7, and the sliding friction between the third universal seat 22 and the ball head 23 in the third ball head adjustment screw 8, the second bracket 2 will drive the first high-beam lens group 3 to deflect up and down with the straight line formed by the second ball head adjustment screw 7 and the third ball head adjustment screw 8 as the axis, so that the projection direction and range of the first high-beam lens group 3 are changed, and overlap with the aiming of the second high-beam lens group 4, thereby increasing the high-beam light intensity and avoiding the interference of the double light spots of the first high-beam lens group 3 and the second high-beam lens group 4. If it is necessary to adjust the first high-beam lens group 3 forward and backward, the third ball head adjustment screw 8 can be rotated to fine-tune the axial movement of the third ball head adjustment screw 8, which will cause the third universal seat 22 to deflect. At the same time, due to the sliding friction between the second universal seat 21 and the ball head 23 in the second ball head adjustment screw 7, and the sliding friction between the first universal seat 20 and the ball head 23 in the first ball head adjustment screw 6, the second bracket 2 will drive the first high-beam lens group 3 to deflect forward and backward with the straight line formed by the first ball head adjustment screw 6 and the second ball head adjustment screw 7 as the axis, so that the projection direction and range of the first high-beam lens group 3 are changed, and overlap with the aiming of the second high-beam lens group 4.

[0028] The LED dual high-beam lens group provided by the present invention, in a specific application process, when the driver needs to perform dimming operation, first adjusts the dimming screw (not shown) connected to the second high-beam lens group 4. After the illumination of the second high-beam lens group 4 is adjusted, according to the actual need of overlapping the illumination of the first high-beam lens group 3 with the illumination of the second high-beam lens group 4, if the first high-beam lens group 3 needs to be adjusted left and right, the first ball head adjustment screw 6 is rotated to fine-tune, and if the first high-beam lens group 3 needs to be adjusted front and back, the third ball head adjustment screw 8 is rotated to fine-tune, thereby realizing independent dimming, and achieving while enhancing the visibility of the distant scene illumination, eliminating the interference of the double light spots, so that the illumination of the distant scene by the car headlights is more in line with the driver's observation habits, and the driver's flexibility in responding to distant obstacles is improved, so that various emergency responses can be made in time, thereby reducing the occurrence of traffic accidents.

[0029] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
