With the application of digital light processing (DLP) technology in vehicle lamp imaging, more and more vehicle lamps require precise focal length control to ensure clear images at different distances. To solve this problem, the present invention introduces an autofocus system that combines an electronic rangefinder and a telescopically adjustable vehicle lamp module, and adjusts the focal length in real time by automatically measuring the distance, so as to achieve the purpose of optimizing the imaging effect.

[0049] The first sliding sleeve 2 is connected to the first transmission nut 5 through a transmission pin 10. The first transmission nut 5 is connected to the first threaded sleeve 7 through a pin 11. The first threaded sleeve 7 is fixedly connected to the input bolt 9 through a keyway; when the input bolt 9 rotates, the first threaded sleeve 7 is driven to rotate through the keyway transmission. The second sliding sleeve 3 is connected to the second transmission nut 6 through a transmission pin.

[0050] The headlight module system further includes: a third sliding sleeve 4; the third sliding sleeve 4 is slidably sleeved in the second sliding sleeve 3; a second threaded sleeve 8 is rotatably arranged on the second transmission nut 6, a first threaded sleeve 7 passes through the second transmission nut 6 and is connected to the second threaded sleeve 8, and the first threaded sleeve 7 can drive the second threaded sleeve 8 to rotate; the second threaded sleeve 8 is threadedly connected to the third sliding sleeve 4; a lens 12 is arranged at one end of the third sliding sleeve 4 away from the drive motor 13; when the drive motor 13 drives the input bolt 9 to rotate, the first sliding sleeve 2, the second sliding sleeve 3 and the third sliding sleeve 4 simultaneously expand and contract to adjust the distance between the DLP component 14 and the lens 12.

[0051] The second transmission nut 6 and the second threaded sleeve 8 are connected by a pin. The second threaded sleeve 8 and the first threaded sleeve 7 are fixedly connected through a keyway; when the first threaded sleeve 7 rotates, the second threaded sleeve 8 is driven to rotate through the keyway.

[0052] The headlight module system further includes: a ranging component and a control component; the ranging component is connected to the control component, and the control component is connected to the drive motor 13; the ranging component is used to measure the distance between the headlight and the object in front in real time and transmit the measured distance data to the control component, and the control component controls the drive motor 13 to drive the input bolt 9 according to the received distance data to adjust the distance between the lens 12 and the DLP component 14.

[0053] The driving motor 13 drives the input bolt 9 to rotate. The inner side of the first transmission nut 5 is threadedly connected to the input bolt 9, and the outer side is fixed to the first sliding sleeve 2 through a transmission pin 10. The first sliding sleeve 2 is fixed to the outer sleeve 1 through a keyway (a slide rail is also acceptable). Driving the bolt 9 to rotate drives the first transmission nut 5 to move axially in a straight line. The first transmission nut 5 drives the first sliding sleeve 2 to move axially in a straight line through the transmission pin 10. The first threaded sleeve 7 is connected to the first transmission nut 5 through a pin 11, and the first threaded sleeve 7 is fixed to the input bolt 9 through a keyway. When the input bolt 9 rotates, it drives the first threaded sleeve 7 to rotate through keyway transmission. At the same time, the first threaded sleeve 7 moves axially in a straight line under the push of the first transmission nut 5; the inner side of the second transmission nut 6 is threadedly connected to the first threaded sleeve 7, and the outer side is fixed to the second sliding sleeve 3 through a transmission pin. The second sliding sleeve 3 is fixed to the first sliding sleeve 2 through a keyway (a slide rail is also acceptable). The rotation of the first threaded sleeve 7 drives the second transmission nut 6 to move axially in a straight line. The second transmission nut 6 drives the second sliding sleeve 3 to move axially in a straight line through the transmission pin. The second transmission nut 6 is connected to the second threaded sleeve 8 through a pin, and the second threaded sleeve 8 is fixed to the first threaded sleeve 7 through a keyway. When the first threaded sleeve 7 rotates, it drives the second threaded sleeve 8 to rotate through the keyway. At the same time, the second threaded sleeve 8 moves axially in a straight line under the push of the second transmission nut 6; the second threaded sleeve 8 is threadedly connected to the third sliding sleeve 4, and the third sliding sleeve 4 is fixed to the second sliding sleeve 3 through a keyway (a slide rail is also acceptable).

[0054] This embodiment has multiple layers of sleeves, with the advantages of a larger focusing range and more accurate focusing accuracy. Since the multiple layers of sleeves are driven by the input bolt, and the input bolt is fixed to the first threaded sleeve and the second threaded sleeve through keyways, they rotate synchronously, so the multiple layers of sleeves expand simultaneously.

[0055] This embodiment also provides a vehicle, including the headlight module system with the above-mentioned lens that can be telescopically adjusted.

[0056] The ranging component 10 is an electronic rangefinder. The DLP component 5 is a DLP lamp.

[0057] As Figure 1 shown, it is the state where the first sliding sleeve 2, the second sliding sleeve 3, and the third sliding sleeve 4 are fully extended, and the distance between the lens 12 and the DLP component 14 is the maximum. As Figure 2 shown, it is the state where the first sliding sleeve 2, the second sliding sleeve 3, and the third sliding sleeve 4 are fully retracted, and the distance between the lens 12 and the DLP component 14 is the minimum.

[0058] In other embodiments, the input bolt 9 can be replaced with a lead screw, and the drive motor 13 can drive the lead screw to rotate through transmission gears.

[0059] The thick-walled part of this embodiment is a multi-layer sliding sleeve structure. In the case of limited modeling space, the stroke range of the multi-layer sliding sleeve is longer, and the accompanying focal length adjustment range is wider. The mechanical movement of the multi-layer sliding sleeve is more beautiful under the illumination of the light source. When not in use, the sleeve of the outer lens ring can be retracted inside the multi-layer sleeve, which can effectively protect the outer lens from scratches. Multiple power sources can also be set for the multi-layer sliding sleeve to be controlled separately, increasing the movement stability. When one sleeve cannot work effectively, the rest of the sleeves can be controlled to expand and contract independently to complete zooming.

[0060] The purpose of distance measurement is to determine the focal length for DLP projection, and the preset point is the distance between the two points of DLP and the projection surface. The electronic distance measurer can use laser reflection ranging.

[0061] Emit laser: When the operator presses the measurement button, the laser emitter will emit a laser beam.

[0062] Receive laser: After the laser beam irradiates the target object, it will be reflected by the target object. The receiver will receive the reflected laser signal.

[0063] Calculate the time difference: After the receiver receives the laser signal, it will record the time point when the signal is received.

[0064] Calculate the distance: Based on the propagation speed of light and the time point of receiving the signal, the electronic distance measurer can calculate the distance between the target object and the distance measurer.

[0065] The present invention uses a drive motor, an input bolt, and a multi-layer thread sleeve joint adjustment system in cooperation with an electronic distance measurer to realize that the lens can be automatically expanded and contracted, so as to achieve a clear image effect for the DLP imaging of vehicle lights at different distances.
