[0002] At present, since the installation position of the headlights is fixed, it is easy to cause the installation position of the headlights to shift after the car has been running for a long time. The headlight adjuster mainly adjusts the overall position of the headlights so that the light beam can be directed horizontally to the road surface, so that the light is not too high and the road surface cannot be seen clearly, or the light is not too low and the light cannot be far. Summary of the invention

[0003] In response to the technical problem of the offset of the installation position of the car light raised in the background technology, the present invention aims to provide a car light adjuster with a manual adjustment function, wherein the adjustment rod threadedly connected to the inside of the telescopic tube is moved by the movement of the telescopic tube to realize electric adjustment, and the adjustment stroke of the electric adjustment is fixed; and then the manual adjustment member is rotated to drive the adjustment rod to move in the telescopic tube to realize manual adjustment, so as to increase the total adjustment stroke.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] An automobile headlight adjuster with a manual adjustment function comprises a housing, a power member, a transmission gear assembly and a telescopic device, wherein the power member and the transmission gear assembly are both installed inside the housing, the power member is drivingly connected to the telescopic device through the transmission gear assembly, the telescopic device comprises a telescopic cylinder, an adjustment rod with one end disposed inside the telescopic cylinder and the other end disposed outside the telescopic cylinder, a spiral convex strip is disposed inside the inner side wall of the telescopic cylinder, an end of the adjustment rod disposed inside the telescopic cylinder is provided with an external thread, and the spiral convex strip is threadedly connected to the external thread;

The peripheral side of the adjusting rod is sleeved with a manual adjusting member, and the manual adjusting member includes an integrally formed finger shifting portion and a driving portion. The finger shifting portion is composed of a plurality of fingers, and gaps are left between the plurality of fingers. The arc length of the gaps is greater than or equal to the arc length of the fingers. The inner side wall of the finger shifting is provided with shifting teeth, and the shifting teeth are meshed with the adjusting rack.

[0007] The movement of the telescopic cylinder drives the adjustment rod threadedly connected therein to move, thereby realizing electric adjustment; the rotation of the manual adjustment member drives the adjustment rod to move in the telescopic cylinder, thereby realizing manual adjustment.

[0008] Through the above technical solution, the movement of the telescopic cylinder drives the adjustment rod threaded inside it to move, realizing electric adjustment; the rotation of the hand-adjusting piece drives the adjustment rod to move inside the telescopic cylinder, realizing manual adjustment. The purpose of setting the gap is that when the adjustment stroke is adjusted to the position of the absolute stroke, although the finger itself can continue to rotate, it bends outward, thus failing to play the actual manual adjustment role, and having the same effect as slipping threads; moreover, the gap between the teeth is set to be greater than or equal to the arc length of the finger itself, so that when the adjustment stroke is adjusted to the position of the absolute stroke, the finger is more convenient to bend outward and is not prone to getting stuck.

[0009] The present invention is further configured as follows: the housing includes a base shell and a cover shell, the power member and the transmission gear assembly are installed on the base shell, and the cover shell is installed on the base shell and covers the power member and the transmission gear assembly therein.

[0012] Through the above technical solution, the transmission gear assembly is mainly used to transmit the power of the power part to the telescopic cylinder, and the transmission gear assembly drives the telescopic cylinder to perform telescopic movement forward and backward to achieve the purpose of adjusting the high and low beams of the car lights.

[0013] The present invention is further configured as follows: a guide strip is provided on the circumferential side of the telescopic cylinder, a guide groove is provided in the second gear, and the guide strip is slidably connected in the guide groove.

[0014] Through the above technical solution, the guide strip is provided to make the telescopic movement of the telescopic tube more stable, so that the light of the car headlight is more stable when being adjusted, and the light is not easy to shake.

[0015] The present invention is further configured such that: a driving gear is provided on the peripheral side of the driving part.

[0016] Through the above technical solution, a driving shift gear is provided, and a gear can be externally connected to the driving shift gear, so that the external gear can be conveniently adjusted to the position of the car steering wheel for manual adjustment.

[0017] The present invention is further configured as follows: one end of the adjusting rod provided with an external thread is provided with a guide head of one quarter of the length, the spiral ridge is set to be three quarters of the length of the circumference of the external thread, and the spiral ridge leaves a one quarter guide opening.

[0018] Through the above technical solution, the guide head and the guide port are provided, which are mainly used to accurately align the installation position of the adjusting rod when installing the adjusting rod, thereby improving the installation efficiency.

[0019] The present invention is further configured as follows: a positioning rod is axially penetrated through the coaxially arranged turbine and the first gear, the positioning rod is rotatably installed at the axial center position of the turbine and the first gear, and the two ends of the positioning rod are respectively fixed to the base shell and the cover shell.

[0020] Through the above technical solution, a positioning rod is provided, so that the first gear is not easy to shake along its radial direction when rotating, so that the transmission is more stable.

[0021] The present invention is further configured as follows: an anti-collision opening is provided on the cover shell, and the anti-collision opening is located at the end of the worm.

[0022] Through the above technical solution, since the vortex rod is prone to rocking and shifting along its axial direction when moving, when the end of the vortex rod shifts to the inner wall of the shell and contacts the inner wall of the shell, it is easy to generate noise and wear. Therefore, an anti-collision hole is opened on the inner wall of the cover shell to provide a moving stroke for the end of the vortex rod, so that the regulator is not easy to generate noise and wear during use.

[0023] In summary, the present invention has the following beneficial effects:

[0024] (1) The telescopic tube moves to drive the adjusting rod threaded inside to move, thus achieving electric adjustment; the manual adjustment member is rotated to drive the adjusting rod inside the telescopic tube to achieve manual adjustment;
