Description
Technical Field
[0001] The utility model relates to the technical field of vehicle lamps, in particular to a multiple dimming mechanism for a high and low beam combination vehicle lamp. Background Art
[0002] Before leaving the factory, the high and low beam headlights are adjusted to the appropriate angles to meet regulatory requirements and provide optimal lighting performance. However, factors such as vehicle vibration and changes in the number of passengers can cause these factory-set angles to shift, necessitating further adjustments. This adjustment involves both horizontal and vertical adjustments, with horizontal adjustment oscillating the headlight's direction left and right, and vertical adjustment oscillating the direction up and down.
[0003] Previously, most high and low beam headlights required two separate vertical and horizontal adjustment mechanisms. While this approach met regulatory requirements, it not only increased the number of internal components, occupied limited installation space, and increased manufacturing costs. To address this, we developed a shared high and low beam adjustment mechanism that achieves both high and low beam dimming. Furthermore, we integrated a separate high beam dimming mechanism into this integrated dimming system, resulting in a low cost, compact structure, high space utilization, and comprehensive functionality.

DETAILED DESCRIPTION
[0026] In order to enable ordinary technicians in this field to fully understand the technical solutions and beneficial effects of the utility model, further description is given below in conjunction with specific embodiments and drawings.
[0027] like Figure 1-10 The low-beam combined headlight dimming mechanism shown mainly comprises a low-beam module system (1), a high-beam module system (2), a vertical adjustment system (3), a horizontal adjustment system (4), a housing (5), and a rear cover (6). The low-beam module system (1) and the high-beam module system (2) are fixedly connected by screws and threaded holes. By rotating different screws, the high-beam module system (2) can be driven to move in the horizontal and vertical directions relative to the low-beam module system (1), thereby realizing the high-beam fine-dimming function. A horizontal slide groove and a vertical slide groove are provided on the housing (5). The vertical adjustment system (3) and the horizontal adjustment system (4) are respectively connected to the housing (5) through corresponding slide grooves and can slide along their respective slide grooves. When the vertical adjustment system (3) slides, it drives one side of the low-beam module system (1) to move up and down, thereby realizing the vertical integrated dimming of the high-beam and low-beam; when the horizontal adjustment system (4) slides, it drives the other side of the low-beam module system (1) to move up and down, thereby realizing the horizontal integrated dimming of the high-beam and low-beam.
[0028] like Figure 3-4As shown, the low beam module system (1) includes a low beam module (1-1), a low beam module bracket (1-2), a fixed point ball head seat (1-3), a fixed point ball head seat bracket (1-4), a motor ball head seat (1-5), a screw hole (1-6), and a connecting shaft (1-7). The low beam module (1-1) is vertically fixed to the mounting hole in the middle of the low beam module bracket (1-2) by screws on both sides, the fixed point ball head seat (1-3) is horizontally fixed to the fixed point ball head seat bracket (1-4), and the fixed point ball head seat bracket (1-4) and the motor ball head seat (1-5) are vertically fixed to the low beam module bracket (1-2) by their own snap-fit structures, thereby forming the low beam module system (1). The low beam module system (1) is connected and fixed to the fixed point screw hole on the inner surface of the housing (5) by the fixed point ball head seat bracket (1-4). A plurality of screw holes (1-6) and a connecting shaft (1-7) are provided on the surface of the low beam module bracket (1-2) in the vertical direction and on the side in the horizontal direction. The high beam module system (2) and the horizontal adjustment system (4) are connected to the low beam module bracket (1-2) through these screw holes and the connecting shaft respectively and move synchronously.
[0029] like Figure 5-6 As shown, the high beam module system (2) includes a high beam module (2-1), a high beam module bracket (2-2), a high beam ball cap (2-3), a high beam adjustment screw (2-4), and a high beam fixing ball screw (2-5). The low beam module (1-1) and the high beam module (2-1) are split, and both are provided with light sources. When powered on, they respectively realize the low beam and high beam functions. The high beam module (2-1) is also vertically fixed to the mounting hole in the middle of the high beam module bracket (2-2) by screws on both sides. The high beam ball cap (2-3) is fixedly connected to the top of the high beam adjustment screw (2-4) and the high beam fixing ball screw (2-5), and is vertically fixed to the screw hole on the high beam module bracket (2-2) by the snap structure of the high beam ball cap (2-3), thereby forming the high beam module system (2). The high beam adjustment screw (2-4) and the high beam fixing ball screw (2-5) are passed through the screw holes (1-6) on the high beam module bracket (2-2) and the low beam module bracket (1-2) in the vertical direction, and then the two are fixed together. By rotating the tops of the left and right high beam adjustment screws (2-4), the high beam module system (2) can be driven to move in the horizontal and vertical directions relative to the low beam module system (1), thereby realizing the high beam fine-dimming function.
[0030] The housing (5) is provided with a horizontal slide groove and a vertical slide groove. The vertical adjustment system (3) is slidably connected to the housing (5) via the vertical slide groove, and the horizontal adjustment system (4) is slidably connected to the housing (5) via the horizontal slide groove, thereby realizing the horizontal and vertical adjustment functions of the vehicle light. The specific process is as follows:
[0031] like Figure 7-8As shown, the vertical adjustment system (3) includes a motor bracket (3-1), a motor (3-2), an adjustment screw (7), a metal retaining spring (8), and an adjustment nut (9). After the adjustment nut (9) and the bottom of the adjustment screw (7) are horizontally engaged, they are fixed together in the adjustment nut hole of the housing (5). The middle part of the adjustment screw (7) is vertically fixed to the motor bracket (3-1) through the metal retaining spring (8). The connection between the adjustment screw (7) and the motor bracket (3-1) is a threaded matching structure. The motor (3-2) is vertically fixed on the other side of the motor bracket (3-1). The telescopic ball head of the motor (3-2) is connected to the motor ball head seat (1-5) of the low beam module system (1). Rotating the adjustment nut (9) drives the adjustment screw (7) to rotate, thereby driving the vertical adjustment system (3) as a whole to slide up and down in the vertical slide groove of the housing. Since the vertical adjustment system (3) is connected to the low beam module system (1), the low beam module system (1) is also driven to move synchronously. In addition, when the motor (3-2) is powered on and rotates, the ball head at its end can perform telescopic movement, which can also drive the low beam module system (1) to move, thereby realizing vertical integrated dimming of high and low beams.
[0032] like Figure 9-10 As shown, the horizontal adjustment system (4) includes a horizontal bracket (4-1), an adjustment screw (7), a bushing (4-2), a metal retaining ring (8), and an adjustment nut (9). After the adjustment nut (9) is horizontally engaged with the bottom of the adjustment screw (7), they are fixed together in the adjustment nut hole of the housing (5). The middle part of the adjustment screw (7) is vertically fixed to the horizontal bracket (4-1) through the metal retaining ring (8). The connection between the adjustment screw (7) and the horizontal bracket (4-1) is a threaded matching structure. The bushing (4-2) is horizontally fixed in the mounting hole of the horizontal bracket (4-1), and the connecting shaft (1-7) of the low beam module system (1) is horizontally fixed in the bushing (4-2). Rotating the adjusting nut (9) drives the adjusting screw (7) to rotate, thereby driving the horizontal adjustment system (4) as a whole to slide up and down in the horizontal slide groove of the housing (5). Since the horizontal adjustment system (4) is connected to the low beam module system (1), the low beam module system (1) is also driven to move synchronously, thereby realizing horizontal integrated dimming of high and low beams.
[0033] The rear cover (6) is fixed in the rear cover matching hole on the housing (5). When light adjustment is required, the rear cover (6) is removed and a dimming tool (such as a screwdriver or a sleeve) is inserted from outside the lamp to adjust the light.
[0034] The high and low beam combination headlight has the following three adjustment modes:
[0035] (a) Integrated high-beam and low-beam motor adjustment mode: After the motor (3-2) is powered on, the ball screw at its end is controlled to extend or shorten, driving the motor ball seat (1-5) and the low-beam module bracket (1-2) to rotate around a fixed point, thereby realizing the light adjustment of the low-beam module system (1) and the high-beam module system (2) in the vertical direction.
[0036] (b) Manual fine-tuning mode of the high beam module system (2): The high beam adjustment screw (2-4) is rotated by a tool to move it forward and backward, thereby driving the high beam module bracket (2-2) to rotate around the fixed point, thereby realizing the individual light adjustment of the high beam module system (2) in the vertical and horizontal directions.
[0037] (c) Manual integrated adjustment mode for high and low beams: by rotating the adjustment nut (9) in the horizontal adjustment system (4), the adjustment screw (7) is driven to rotate. Since the adjustment screw (7) is fixed in the housing (5), its rotation drives the horizontal adjustment bracket (4-1) to move up and down in the slide groove of the housing (5), and finally the low beam module bracket (1-2) and the high beam module bracket (2-2) rotate around the fixed point, thereby realizing the horizontal adjustment of the high and low beams; by the same principle, the adjustment nut (9) in the vertical adjustment system (3) is driven to rotate the adjustment screw (7), thereby finally realizing the vertical adjustment of the high and low beams.
[0038] The utility model realizes the integrated dimming function of high and low beams through a set of shared high and low beam adjustment mechanisms. At the same time, a separate dimming mechanism for high beam is integrated on the basis of the integrated dimming. The entire adjustment mechanism has the advantages of low cost, compact structure, high space utilization, and comprehensive functions.
