Description

[0002] Headlights are a tool for vehicles to illuminate the road at night, and are also a tool for issuing various vehicle driving signals.
[0003] In related technologies, headlights are equipped with a light source. When in use, the light beam emitted by the light source needs to be reflected onto the floor or wall. A deflection mechanism is often used to directly adjust the angle of the light beam. However, the light source is large in size and must meet requirements for styling, performance, and functional integration. To ensure sufficient driving force for proper deflection, the deflection mechanism directly acting on the light source is also large. This results in a larger overall module size, a larger dimming envelope, and a limited illumination range. However, automotive headlights are increasingly demanding space requirements.

DETAILED DESCRIPTION
[0039] The following is combined with Figure 1-5 This application is described in further detail.
[0040] The embodiment of the present application discloses a total reflection adjustment device for a light source of a vehicle lamp. Figure 1-2 The total reflection adjustment device for a vehicle light source includes a light source body 1 and a reflection mechanism. The reflection mechanism includes a first driving component, a second driving component, a mounting bracket 2 and a dimming mirror 3. The light beam emitted by the light source body 1 is set toward the dimming mirror 3. The first driving component and the second driving component are arranged on the mounting bracket 2. The first driving component is used to drive the dimming mirror 3 to rotate toward a first direction 4. The second driving component is used to drive the dimming mirror 3 to rotate toward a second direction 5. The rotation axis of the dimming mirror 3 in the first direction 4 is perpendicular to the rotation axis in the second direction 5.
[0041] Light source 1 emits a light beam to dimming mirror 3. The first and second drive assemblies adjust the dimming mirror 3, allowing it to rotate up and down, left and right, and thus reflect the light beam from the light source to a defined range and position, such as the ground or a wall. By configuring the reflective mechanism, the dimming system of this application can achieve a smaller module size and dimming envelope, while also meeting a wider dimming range.
[0042] Reference Figure 1-4 The light source body 1 is any one or more of a film projector lamp, an MLA projector lamp, a low beam lamp, a high beam lamp, a fog lamp, a brake lamp, a turn signal lamp and a position lamp. The type and quantity of the light source can be selected according to actual conditions, and the application range is wide. The mounting frame 2 includes a mounting shell 21 and a mounting plate 22. The mounting plate 22 is fixed to the top surface of the mounting shell 21 by a connecting column 6 and a bolt. Compared with the mounting shell 21, the mounting plate 22 is closer to the dimming mirror 3. The dimming mirror 3 is rotatably connected to the mounting plate 22. The mounting plate 22 is provided with a clearance groove 221 for the dimming mirror 3 to rotate in the first direction 4. The mounting plate 22 and the mounting shell 21 have a simple structure and are easy to install. The setting of the clearance groove 221 provides a clearance space for the rotation of the dimming mirror 3 in the first direction 4.
[0043] Reference Figure 2-4 The light-adjusting mirror 3 includes a frame 31 and a mirror surface 32 mounted on the frame 31. The frame 31 comprises a base plate 311, a vertical plate 312, and triangular side plates 313 disposed at each end of the base plate 311. The mirror surface 32 is mounted on the side of the vertical plate 312 facing away from the base plate 311. The mirror surface 32 and the frame 31 can be manufactured separately and then assembled. This configuration of the frame 31 reduces material consumption while maintaining structural stability, thus helping to save costs.
[0044] Reference Figure 2-4 A rotating column 33 is fixedly connected to the side of the triangular side panels 313 facing away from each other. The rotation axis of the light-adjusting mirror 3 in the first direction 4 coincides with the axis of the rotating column 33. The rotating column 33 is arranged near the mirror surface 32. A rotating cylinder 34 for rotationally connecting the rotating column 33 is provided on the top surface of the mounting plate 22. The arrangement of the rotating column 33 and the rotating cylinder 34 provides a fulcrum for the rotation of the light-adjusting mirror 3. The structure is simple and facilitates the rotation of the light-adjusting mirror 3 in the first direction 4. The side of the bottom plate 311 facing away from the mirror surface 32 is outwardly protruded to form a protrusion 314, and the first drive assembly acts on the protrusion 314. The rotating column 33 and the protrusion 314 are remote from each other, which facilitates the first drive assembly to move a smaller stroke to achieve a wider range of rotation of the light-adjusting mirror 3 in the first direction 4, thereby facilitating the increase of the reflection range of the light-adjusting mirror 3.
[0045] Reference Figure 3-5The first driving assembly includes a first stepper motor 7 and a first connecting head 71. The first stepper motor 7 is fixedly arranged on the bottom surface of the mounting shell 21. The driving shaft of the first stepper motor 7 passes through the mounting shell 21. One end of the first connecting head 71 is movably connected to the driving shaft of the first stepper motor 7, and the other end of the first connecting head 71 is connected to the protrusion 314.
[0046] When the dimming mirror 3 needs to be adjusted in the first direction 4, the first stepper motor 7 is started, and the driving shaft of the first stepper motor 7 is extended and retracted, thereby driving the dimming mirror 3 to rotate around the axis of the rotating column 33 through the first connector 71, thereby realizing the rotation of the dimming mirror 3 in the first direction 4.
[0047] Reference Figure 5 The first connector 71 includes a first vertical tube 711 and a first horizontal tube 712, which are connected to each other. A first upper limit plate 713 and a first lower limit plate 714 are fixedly connected to the first vertical tube 711. The cross-sectional area of the first upper limit plate 713 is smaller than that of the first lower limit plate 714. The protrusion 314 defines a first mounting slot 715 for the first upper limit plate 713 to pass through. The size of the first mounting slot 715 is adapted to the size of the first upper limit plate 713. After passing through the first mounting slot 715, the first upper limit plate 713 rotates to be offset from the first mounting slot 715. The cross-section of the first horizontal tube 712 is Ω-shaped. The axis of the first horizontal tube 712 is perpendicular to the rotation axis of the dimming mirror 3 in the first direction 4. The end of the drive shaft of the first stepper motor 7 is spherical and snaps into the first horizontal tube 712.
[0048] When installing the first connector 71, the first upper limit plate 713 is passed through the first mounting slot 715 from bottom to top. The first vertical tube 711 is then rotated 90° along its axis. The first vertical tube 711 is then restrained on the mounting plate 22 by the first upper limit plate 713 and the first lower limit plate 714. The spherical end of the first stepper motor 7 drive shaft is then inserted into the end of the first transverse tube 712, facilitating the connection and installation between the mirror frame 31 and the first stepper motor 7. Simultaneously, the end of the first stepper motor 7 is slidably connected to the first transverse tube 712 via a ball hinge, facilitating the vertical rotation of the light-adjusting mirror 3.
[0049] Reference Figure 3-4The second drive assembly includes a second stepper motor 8 and a second connector 81. The second stepper motor 8 is fixedly mounted within the vehicle lamp. One end of the second connector 81 is movably connected to the drive shaft of the second stepper motor 8, and the other end of the second connector 81 is connected to the side of the mounting housing 21. When the dimming mirror 3 needs to be adjusted in the second direction 5, the second stepper motor 8 is activated, and the drive shaft of the second stepper motor 8 is extended and retracted, thereby driving the mounting frame 2 as a whole to rotate along the rotation axis in the second direction 5 via the second connector 81, thereby achieving rotation of the dimming mirror 3 in the second direction 5.
[0050] Reference Figure 3-4 The second connector 81 includes a second vertical tube 811 and a second horizontal tube 812, which are interconnected. A second upper limit plate 813 and a second lower limit plate 814 are fixedly connected to the second vertical tube 811. The cross-sectional area of the second upper limit plate 813 is smaller than that of the second lower limit plate 814. A second mounting slot 815 is defined on the side of the mounting housing 21 for the second upper limit plate 813 to pass through. The size of the second mounting slot 815 is adapted to the size of the second upper limit plate 813. After passing through the second mounting slot 815, the second upper limit plate 813 rotates to be offset from the second mounting slot 815. The second horizontal tube 812 has an Ω-shaped cross-section. The axis of the second horizontal tube 812 is perpendicular to the rotation axis of the dimming mirror 3 in the second direction 5. The end of the drive shaft of the second stepping motor 8 is spherical and engages with the second horizontal tube 812.
[0051] When installing the second connector 81, the second upper limit plate 813 is passed through the second mounting slot 815 from bottom to top, and then the second vertical tube 811 is rotated along the axis of the second vertical tube 811, for example, by 90 degrees. The second vertical tube 811 is restrained on the side wall of the mounting shell 21 by the second upper limit plate 813 and the second lower limit plate 814. Then, the spherical end of the drive shaft of the second stepper motor 8 is inserted into the end of the second transverse tube 812, thereby facilitating the connection and installation between the mounting frame 2 and the second stepper motor 8. At the same time, the end of the second stepper motor 8 is connected to the second transverse tube 812 in a slidable manner using a ball hinge, facilitating the left and right rotation of the mounting frame 2, and thereby facilitating the left and right rotation of the dimming mirror 3.
[0052] The implementation principle of a total reflection adjustment device for a light source for a vehicle lamp in an embodiment of the present application is as follows: a light source emits a light beam to a dimming mirror 3, and the dimming mirror 3 is adjusted by a first driving component and a second driving component so that the dimming mirror 3 can be rotated up and down and left and right, thereby causing the dimming mirror 3 to reflect the light beam emitted by the light source to a defined range and position state, such as the ground or a wall; through the setting of the reflection mechanism, the dimming form of the present application can produce a smaller module size and dimming envelope, while at the same time meeting a larger dimming range.
[0053] When installing the reflection mechanism, first install the second connector 81 on the mounting shell 21, and then connect the driving shaft of the second stepper motor 8 to the second connector 81; then install the first stepper motor 7, and then connect the first connector 71 to the driving shaft of the first stepper motor 7, connect the rotating column 33 and the rotating cylinder 34, and then connect the first connector 71 to the bottom plate 311, and finally connect the mounting plate 22 to the mounting shell 21. The structure is simple and the installation is quick and convenient.
[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
