[0036] DETAILED DESCRIPTION
[0037] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.
[0038] The present invention provides an adjustment mechanism for a vehicle lamp module, referring to Figure 1-Figure 9 As shown, the adjustment mechanism is mainly composed of a headlight module 1, a first adjustment bracket 4 and a second adjustment bracket 5; wherein the headlight module 1 is rotatably connected to the first adjustment bracket 4 in the vertical direction, and the headlight module 1 is adjusted in pitch and rotation on the first adjustment bracket 4; the first adjustment bracket 4 is rotatably connected to the second adjustment bracket 5 in the horizontal direction, and the first adjustment bracket 4 is arranged to move up and down in the horizontal direction on the second adjustment bracket 5. Through the first adjustment bracket 4 and the second adjustment bracket 5, the headlight module 1 can not only be rotated in the horizontal direction, but also be translated up and down, which can compensate for the shading problem caused by the rotation adjustment of the module in the lamp. The external mirror of the headlight can be made smaller, hidden in the car body, and the shape design is more flexible.
[0039] The vehicle lamp module 1 includes a module bracket 2 and a module heat sink 3. Two second ball head seats 15 are arranged on the module bracket 2 and installed on two side walls of the vehicle lamp module 1 along the X direction. Two first ball head seats 8 are arranged on the module heat sink 3 and are located on the same side of the vehicle lamp module 1 along the Y direction. The first ball head seat 8 and the second ball head seat 15 are pre-installed on the vehicle lamp module 1 to form a module assembly 12.
[0040] A pair of ball head seat profiling grooves 21 are provided on the first adjustment bracket 4, and a pair of second ball head seats 15 on the module assembly 12 are respectively installed in the two ball head seat profiling grooves 21, and then covered by two ball head brackets 9, and the two sides of the ball head bracket 9 are locked by two screws 11. A screw base 7 is installed on one end of the first adjustment bracket 4 along the Y direction, and a vertical adjustment screw 6 is provided on the screw base 7. The vertical adjustment screw 6 is rotated and adjusted along the Y direction, and one end of the vertical adjustment screw 6 is embedded in a first ball head seat 8 of the module assembly 12. By rotating the vertical adjustment screw 6, the module assembly 12 is rotated and adjusted along the X axis. At this time, the rotation axis of the module assembly 12 on the first adjustment bracket 4 is the vertical adjustment axis. A lens is installed at the front end of the module assembly 12 along the Y direction, and the vertical adjustment axis is set close to the lens side, so that the space occupied by the front end during rotation adjustment can be smaller, reducing the impact on the molding space.
[0041] A third ball head seat 22 is installed at the top of the first adjustment bracket 4 along the Z direction, and spring pins 19 are respectively provided at both ends of the bottom of the first adjustment bracket 4 along the Z direction. The third ball head seat 22, the vertical adjustment screw 6 and the screw base 7 are pre-installed on the first adjustment bracket 4 to form the first adjustment bracket subassembly 13. The module assembly 12 is installed on the first adjustment bracket subassembly 13 to form the module pre-assembly assembly 16.
[0042] An up-down translation adjustment screw 18 is installed on the inner side of the top of the second adjustment bracket 5 in the Z direction. The up-down translation adjustment screw 18 is arranged to rotate and adjust in the Z direction. Two spring latch stopper grooves 20 are arranged at two corresponding positions at the bottom of the second adjustment bracket 5 in the Z direction. During installation, a compression spring is installed on each of the two spring latches 19, and the third ball head seat 22 on the first adjustment bracket subassembly 13 is pressed into the up-down translation adjustment screw 18 on the second adjustment bracket 5. The two spring latches 19 are respectively installed in the two spring latch stopper grooves 20. By rotating the up-down translation adjustment screw 19, the module pre-assembly assembly 16 translates up and down in the Z direction in the second adjustment bracket 5 under the action of the compression spring.
[0043] A horizontal adjustment screw 17 is installed at one end of the second adjustment bracket 5 along the Y direction. The horizontal adjustment screw 17 and the up-and-down translation adjustment screw 18 are installed on the second adjustment bracket 5 to form a second adjustment bracket subassembly 14 .
[0044] Install the module pre-assembly assembly 16 in the second adjustment bracket sub-assembly 14, first insert the compression spring 10 into the spring latch 19 in the module pre-assembly assembly 16, then insert the module pre-assembly assembly 16 obliquely aligned with the spring latch limit groove 20 on the second adjustment bracket sub-assembly 14, press the compression spring 10 to the bottom and align it with the upper side of the vertical translation adjustment screw 18, and align the third ball head seat 22 and press it in. Another first ball head seat 8 of the module sub-assembly 12 is pressed into the horizontal adjustment screw 17. The horizontal adjustment screw 17 is offset on the second adjustment bracket 4. When the horizontal adjustment screw 17 is rotated, the module pre-assembly assembly 16 rotates horizontally with the vertical translation adjustment screw 18 as the rotation axis. Since the size of the spring latch limiting groove 20 is larger than that of the spring latch 19, when the module pre-assembly assembly 16 rotates horizontally, the two spring latches 19 simultaneously translate in the spring latch limiting groove 20, and the spring latch limiting groove 20 limits the rotation angle of the module pre-assembly assembly 16. At this time, the axis of the vertical translation adjustment screw 18 is the horizontal adjustment axis.
[0045] The installation methods of the horizontal adjustment screw 17 and the up-and-down translation adjustment screw 18 are the same as the installation method of the vertical adjustment screw 6 .
[0046] The vertical adjustment axis and the horizontal adjustment axis are arranged close to the corresponding symmetry center, so that the space occupied by the rotation adjustment is smaller. For the headlight module 1, the vertical adjustment axis is arranged close to the module lens side, so that the space occupied by the front end rotation adjustment is smaller.
[0047] By adjusting the screw rod 18 and the compression spring, the module can be adjusted up and down in the lamp, and the adjustment space of the module can be optimized on the basis of the original rotation adjustment. The shading problem caused by the rotation adjustment of the module in the lamp can be compensated. The exterior mirror of the lamp can be made smaller and hidden in the car body, and the design is more flexible.
[0048] The headlight module 1 realizes vertical rotation on the first adjustment bracket subassembly 13 through the vertical adjustment shaft, realizes vertical translation of the headlight module 1 on the second adjustment bracket subassembly 14 along with the first adjustment bracket subassembly 13 through the up and down translation adjustment screw, and realizes horizontal rotation of the headlight module 1 on the second adjustment bracket subassembly 14 along with the first adjustment bracket subassembly 13 through the horizontal adjustment shaft. The above is only a preferred embodiment of the present invention and should not be construed as a limitation to the present application. In another embodiment, vertical rotation adjustment and horizontal rotation adjustment can be realized between the first adjustment bracket subassembly 13 and the second adjustment bracket subassembly 14, and up and down translation adjustment can be realized between the module and the first adjustment bracket subassembly 13.
[0049] In this embodiment, the light source is configured as a SMD LED, which is integrated on a PCBA or a heat sink and connected to the PCB board via a metal wire. In other embodiments, other light source types may be selected according to actual needs.
[0050] The present invention can be configured to generate multiple light distributions, the types of which are different, and the type of each light distribution is any one of the following: low beam lighting, high beam lighting, adaptive low beam lighting, ADB high beam lighting, corner fog lamp lighting, urban road mode lighting, country road mode lighting, highway mode lighting, curve mode lighting, rain and fog mode lighting, position signal lights, turn signal lights, daytime running lights, welcome lights, ambient lights, etc.
