Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp manufacturing, in particular to an adjustment device for an ADB lens module. Background Art

[0002] ADB is an intelligent high beam control system that can adaptively change the high beam pattern according to road conditions. ADB uses intelligent control to replace manual switching, making lighting control more convenient and comfortable; at the same time, anti-glare light pattern change replaces high and low beam switching, which expands the field of vision lighting while ensuring road safety.

[0003] The optical module corresponding to the high beam control system is the ADB lens module. The ADB lens module has a light pattern calibration process during the production process. Specifically, the light pattern of the lens module is controlled by adjusting the length of the two ball screws on the lens module until it is adjusted to the optically required position.

[0004] The defects of the prior art are: the ball screw is manually adjusted using a tool, which is inefficient, the adjustment accuracy is difficult to control, and the calibration process is cumbersome. Utility Model Content

[0005] The purpose of the utility model is to provide an adjustment device for an ADB lens module to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model proposes a solution: using a cylinder to provide thrust, so that the tool is aligned with the tail of the ball head screw and clamps the tail of the screw, and then using a servo motor to provide a rotational load, so that the tool drives the screw to rotate until the lens module reaches the required lighting light type.

[0007] Specifically, the present solution provides an adjustment device for an ADB lens module, which is used to adjust a screw on the ADB lens module so that the ADB lens module obtains a desired lighting light type; the adjustment device specifically includes a first component, the first component has a first end portion connected to the tail end of the screw, and the first end portion is configured to transmit a rotational load to the tail end of the screw; the second component is connected to the first component so that the second component can transmit a rotational load to the first component; and an elastic component is used to provide an elastic deformation force to the second component so that the first component can undergo a linear displacement relative to the second component under the action of the deformation force;

[0008] The adjustment device designed in this way only needs to use a power source to provide a controllable rotational load to the second component, so as to drive the second component and the screw to rotate in turn. At the same time, the elastic member also provides a thrust to the screw by acting on the second component, so that the screw is continuously subjected to the thrust and is continuously driven to rotate, thereby adjusting the lighting light pattern of the lens module through the screw until the required lighting light pattern is obtained. It has the technical effects of high efficiency, controllable precision and simple operation.

[0009] Preferably, the first component is a cylindrical member, and the first end is a non-circular cylindrical cavity recessed in one end of the cylindrical member, so that the tail end of the screw can extend into the non-circular cylindrical cavity to form a connection, that is, the shape of the non-circular cylindrical cavity matches the shape of the tail end of the screw, thereby driving the screw to rotate.

[0010] Preferably, the adjusting device also includes a third component, which is fixedly connected to the first component and connected to the second component via a pin and a pin groove formed on the third component, so that the second component can transmit the rotational load to the first component via the third component, that is, the first component and the second component are connected via the third component, and the force is transmitted via the third component.

[0011] Preferably, the pin groove extends along the screwing direction of the screw, so that the third component can be linearly displaced relative to the second component along the screwing direction of the screw, that is, when the third component is driven to rotate by the second component under the connecting action of the pin, since the pin groove is extended, it can also be linearly displaced relative to the second component, thereby driving the first component to be linearly displaced.

[0012] Preferably, the second component is a cylindrical component, the elastic component is a cylindrical spring placed in the cylindrical component, and the third component extends into the cylindrical component and abuts against the cylindrical spring, so that the third component can be deformed by the cylindrical spring to produce linear displacement.

[0013] Preferably, the regulating device further comprises a power assembly, the output end of the power assembly is connected to the second component to provide a rotational load to the second component.

[0014] Preferably, the power assembly includes: a motor; a first pulley connected to the output end of the motor; a second pulley fixedly connected to the second component; and a belt connecting the first pulley and the second pulley;

[0015] In this way, the motor is used to provide a rotational load to drive the first pulley to rotate, and then the second pulley is driven to rotate through the transmission effect of the belt, so that the rotational load can be transmitted to the second component.

[0016] Preferably, the adjusting device further comprises a first cylinder, the output end of which is connected to a power assembly, so as to drive the second component to undergo linear displacement through the power assembly, thereby controlling the first component to be connected to or disconnected from the tail of the screw.

[0017] Preferably, the adjusting device further comprises a seat member, which is used to support and fix the ADB lens module, so that the ball screw on the ADB lens module corresponds to the first component after fixation. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Further, such as Figure 2 A roller 12 is also provided on the power assembly. The roller 12 abuts against the belt 9 for tensioning the belt 9 , and the position of the roller 12 is adjustable to adjust the tension of the belt 9 .
