Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a headlight high / low beam adjustment linkage. Background Technology

[0002] The headlight high / low beam adjustment linkage is a crucial mechanical component in a car's headlight system. It cleverly connects the headlight's high / low beam switching mechanism to the driver's control interface. When the driver operates the headlight switching lever or knob inside the vehicle, this linkage acts as a force transmission medium, accurately transmitting the operator's commands from the driver's cabin to the headlight assembly. Its design typically balances flexibility and durability, ensuring smooth operation even under frequent, prolonged use, and adapting to complex road conditions such as vehicle vibrations. This guarantees timely and accurate switching between high and low beams, providing clear and suitable illumination for nighttime driving and effectively improving driving safety.

[0003] CN209492442U discloses a vehicle headlight adjustment mechanism and a high / low beam headlight assembly. The headlight adjustment mechanism includes: a first transmission component including a first worm gear, a first turbine mounted on the first worm gear, and a second turbine meshing with the first turbine; and a second transmission component including a second worm gear, a third turbine mounted on the second worm gear, and at least one fourth turbine meshing with the third turbine. The fourth turbine has a locking hole for a dimming lever to be inserted. The first worm gear and the second worm gear are coaxially connected, which can shift the dimming insertion point. The use of multiple fourth turbines expands the number of dimming insertion points. However, the headlight assembly adjustment lever is provided in two sets. In the above technology, the two sets of adjustment levers cannot be adjusted synchronously, which greatly increases the adjustment time. Therefore, the above technology still has some room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a headlight high / low beam adjustment linkage to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a headlight high / low beam adjustment linkage, comprising a base plate, wherein a first adjustment rod and a second adjustment rod are provided within the base plate, and an installation groove for mounting the connecting rod is provided on the surface of the base plate. The first and second adjustment rods are axially inserted into the installation groove. One end of the connecting rod is connected to the first adjustment rod via a first transmission structure, and the end of the connecting rod away from the first adjustment rod is connected to the second adjustment rod via a second transmission structure. An adjustment component capable of linkage with the first transmission structure is provided on one side of the base plate. The adjustment component can drive the first and second adjustment rods for adjustment via the first and second transmission structures.

[0006] By adopting the above technical solution, a first adjusting rod and a second adjusting rod are set in the base plate, and an installation groove is opened on the surface of the base plate to accommodate the connecting rod. At the same time, the first transmission structure and the second transmission structure are respectively connected to the two ends of the first adjusting rod, the second adjusting rod and the connecting rod. An adjusting component that can be linked with the first transmission structure is set on one side of the base plate, thereby realizing the synchronous adjustment of the high beam and the low beam. When the adjusting component is operated, it first drives the first adjusting rod to move through the first transmission structure, and then drives the second adjusting rod to perform synchronous adjustment through the connecting rod and the second transmission structure.

[0007] The aforementioned headlight high / low beam adjustment linkage can be further configured as follows: the first transmission structure includes a first transmission gear disposed in the mounting groove, the first adjustment rod is installed at the bottom of the first transmission gear, the connecting rod is provided with a second transmission gear at one end facing the first adjustment rod, the first transmission gear and the second transmission gear mesh, the adjustment member is provided with a third transmission gear at one end facing the first transmission gear, the third transmission gear meshes with the first transmission gear to cause the adjustment member to drive the connecting rod to rotate.

[0008] Using the above technical solution, a first transmission gear is installed in the mounting slot, and a first adjusting rod is installed at its bottom. At the same time, a second transmission gear is installed at the end of the connecting rod facing the first adjusting rod, meshing with it, and a third transmission gear is installed at the end of the adjusting member facing the first transmission gear, meshing with it. This achieves synchronous adjustment of the high beam and low beam. When the adjusting member rotates, the third transmission gear rotates accordingly. Since it meshes with the first transmission gear, it will drive the first transmission gear and the first adjusting rod at its bottom to rotate. Since the second transmission gear is also in a meshing state with the first transmission gear, the rotation of the first transmission gear is further transmitted to the second transmission gear, thereby driving the connecting rod to rotate.

[0009] The aforementioned headlight high / low beam adjustment linkage can be further configured such that: the second transmission structure includes a fourth transmission gear disposed in the mounting groove, the second adjustment rod is mounted on the bottom of the fourth transmission gear, and a fifth transmission gear is provided at the end of the connecting rod away from the second transmission gear, the fifth transmission gear meshing with the fourth transmission gear.

[0010] By adopting the above technical solution, a fourth transmission gear is set in the mounting groove, and the second adjusting rod is installed at its bottom. At the same time, a fifth transmission gear is set at the end of the connecting rod away from the second transmission gear and meshes with it. When the first transmission structure drives the first adjusting rod to move, this action is transmitted to the fifth transmission gear through the connecting rod. Since the fifth transmission gear is tightly meshed with the fourth transmission gear, the motion can be accurately transmitted to the second adjusting rod, so as to realize the synchronous adjustment of the high beam and low beam.

[0011] The aforementioned headlight high / low beam adjustment linkage can be further configured as follows: an adjustment groove for installing an adjustment component is provided on one side of the base plate; the adjustment component includes an adjustment surface for tool adjustment; a rotating ring is provided on one side of the adjustment surface; a rotating groove for the rotating ring to be embedded in the adjustment groove and the mounting groove is provided; a limiting groove is formed between the rotating ring and the third transmission gear; and a limiting groove for the limiting groove to be installed is provided on the side wall of the rotating groove.

[0012] The above technical solution includes an adjustment groove on one side of the base plate, and an adjustment surface and a rotating ring designed on the adjustment component for tool adjustment. A rotating groove is also provided between the adjustment groove and the mounting groove, and a limiting groove and a limiting groove on the side wall of the rotating groove are formed between the rotating ring and the third transmission gear. The setting of the adjustment surface makes adjustment with tools more convenient and efficient, while the cooperation between the rotating ring and the limiting groove and the limiting groove ensures that the adjustment component can be accurately positioned during the adjustment process, avoiding inaccurate adjustment caused by loosening or offset.

[0013] The aforementioned headlight high / low beam adjustment linkage can be further configured as follows: the base plate has a fixing groove on its outer periphery, the mounting groove is placed in the fixing groove, the fixing groove has a plurality of connecting posts on its side wall, the fixing groove has a dust cover plate, the dust cover plate has connecting ears on both sides, and the connecting ears and connecting posts are all provided with connecting holes for bolt installation.

At the same time, several connecting columns are set on the side wall of the fixing groove, and a dust cover is provided in the fixing groove. The dust cover has connecting ears on both sides corresponding to the connecting columns. Both the connecting ears and the connecting columns have connecting holes for bolt installation. This effectively prevents dust, debris and other objects from entering the mounting groove, keeps the transmission components clean and lubricated, and extends their service life.

[0015] The aforementioned headlight high / low beam adjustment linkage can be further configured as follows: the mounting groove includes an axial mounting groove for mounting the connecting rod and a gear mounting groove for mounting the first transmission gear and the fourth transmission gear. The axial mounting groove is connected to the gear mounting groove. The bottom of the first transmission gear and the fourth transmission gear is provided with a rotating block. The gear mounting groove is provided with a connecting groove for mounting the rotating block and an adjusting rod groove for mounting the first adjusting rod and the second adjusting rod. The connecting groove is connected to the adjusting rod groove.

[0016] By adopting the above technical solution, the mounting groove is divided into an axial mounting groove and a gear mounting groove, and the two are connected. At the same time, a rotating block is set at the bottom of the first transmission gear and the fourth transmission gear, and a connecting groove for mounting the rotating block and an adjusting rod groove for mounting the first adjusting rod and the second adjusting rod are set in the gear mounting groove, and the connecting groove and the adjusting rod groove are connected. This realizes the efficient integration and precise adjustment of the high beam and low beam adjustment mechanism. The axial mounting groove provides a stable installation position for the connecting rod, ensuring the linear movement and stability of the connecting rod during the adjustment process.

[0017] The aforementioned headlight high / low beam adjustment linkage can be further configured such that the second, third, and fifth transmission gears are bevel gears.

[0018] By adopting the above technical solution, and using bevel gears as the second, third, and fifth transmission gears, a highly efficient, precise, and compact transmission layout for the high beam and low beam adjustment mechanisms is achieved. Bevel gears have a large contact area and high load-bearing capacity, ensuring stability and reliability during transmission.

[0019] The beneficial effects of this utility model are as follows: by setting a first transmission structure and a second transmission structure, when the adjusting member is operated, it first drives the first adjusting rod to move through the first transmission structure, and then drives the second adjusting rod to make synchronous adjustment through the connecting rod and the second transmission structure.
