Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a dimming adapter structure. Background Technology

[0002] Currently, in existing technologies, vehicle headlights generally require manual adjustment in both horizontal and vertical directions for both high and low beams. Due to limitations in the headlight's own structure and the vehicle's sheet metal structure, direct manual adjustment is not possible; an adapter structure is needed to bring out the adjustment point for manual adjustment. Common headlight adapter structures use a bevel gear transmission between a dimming screw and a dimming adapter rod for adjustment. This structure is greatly affected by space constraints and is not suitable for all headlight designs. Referring to the existing patent CN220228834U, which uses a universal coupling assembly to connect the dimming tool, while solving some of the space constraints within the headlight, it is still limited by the surrounding space of the vehicle body, taking up considerable space and unsuitable for current headlight designs. It cannot meet the need for dimming in smaller spaces; furthermore, the existing structure has a limited angle rotation of the dimming path, and due to its structural limitations, it cannot achieve multi-angle or large-angle adjustments. Additionally, deformation of parts significantly affects the dimming torque, and in severe cases, stripping can occur. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a dimming adapter structure that can adapt to the needs of multi-angle adjustment and small space.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A dimming adapter structure includes a vehicle lamp housing, a dimming component extending out of the vehicle lamp housing, a dimming adapter rod driven to the outside of the dimming component, a dimming gear driven to the end of the dimming adapter rod away from the dimming component, the dimming gear being rotatably mounted on the outside of the vehicle lamp housing, and a first bevel gear suitable for connection with an external dimming power source being driven to the outside of the dimming gear.

[0006] Furthermore, the dimming gear is rotatably mounted on the outside of the headlight housing via a central mounting screw.

[0007] Furthermore, the dimming gear is rotatably sleeved on the outside of the mounting screw, and a pre-tightening groove is provided on the inner side of the headlight housing. The mounting screw passes through the headlight housing and its tightening end cooperates with the pre-tightening groove.

[0008] Furthermore, the dimming gear is a bevel gear.

[0009] Furthermore, one end of the dimming adapter rod engages with the dimming gear via a second bevel gear.

[0010] Furthermore, the second bevel gear and the dimming adapter rod are fitted with an internal hexagonal socket.

[0011] Furthermore, the end of the first bevel gear furthest from the dimming gear has an internal hexagonal structure.

[0012] Furthermore, a support block for supporting the dimming adapter rod is also provided on the outside of the headlight housing.

[0013] Furthermore, the outer side of the headlight housing is also provided with a first support frame for supporting the first bevel gear and a second support frame for supporting the second bevel gear.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] 1. This utility model, through the design of the dimming gear on the outside of the headlight housing, combined with the transmission cooperation of the first bevel gear and the second bevel gear, saves the space occupied by the adapter structure while ensuring normal dimming, and can be adapted to more headlight shapes and meet the needs of smaller spaces.

[0016] 2. This utility model uses a dimming gear as a transition structure, which, together with the transmission of the first bevel gear and the second bevel gear, allows the dimming path to adapt to the needs of multiple angles and large angles. When dimming manually from the outside, the angle is not limited, and dimming can be done quickly, efficiently and conveniently.

[0017] 3. This utility model uses mounting screws to install the dimming gear, and the dimming torque can be adjusted by adjusting the pressing depth of the dimming gear. Therefore, the deformation of the parts has little impact on the dimming torque of the structure. Attached Figure Description

[0022] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] like Figure 1-3 As shown, in this embodiment, a dimming adapter structure is provided, which mainly consists of a headlight housing 1, a dimming component 2, a dimming adapter rod 3, a dimming gear 4, mounting screws 5, a first bevel gear 6, and a second bevel gear 7. Taking a car headlight as an example, the headlight housing 1 has a conventional structure and is set inside the headlight housing 1. The head of the dimming component 2 has a gear and protrudes from the headlight housing 1. One end of the dimming adapter rod 3 also engages with the gear at the head of the dimming component 2 through a gear to achieve a transmission connection. A support block 30 is provided on the outside of the headlight housing 1 to support the dimming adapter rod 3. The end of the dimming adapter rod 3 away from the dimming component 2 is driven and mounted with the dimming gear 4. At the same time, the dimming gear 4 is rotatably mounted on the outside of the headlight housing 1. The first bevel gear 6 meshes with the outside of the dimming gear 4. A first support frame 60 is also provided on the outside of the headlight housing 1 to support the first bevel gear 6. The first bevel gear 6 is suitable for connecting to an external dimming power source.

[0024] Specifically, in this embodiment, the dimming gear 4 is rotatably mounted on the outside of the headlight housing 1 via a central mounting screw 5. That is, the dimming gear 4 is rotatably sleeved on the outside of the mounting screw 5, with a bearing connecting them in the middle. A pre-tightening groove 100 is provided inside the headlight housing 1, and the mounting screw 5 passes through the headlight housing 1. The dimming gear 4 is mounted on the outside of the mounting screw 5, and the tightening end of the mounting screw 5 engages with the pre-tightening groove 100. This allows adjustment of the pre-tightening degree of the mounting screw 5, thereby adjusting the pressing depth of the dimming gear 4 to adjust the dimming torque. Therefore, deformation of the parts has a relatively small impact on the dimming torque of the structure.

[0025] Specifically, in this embodiment, the dimming gear 4 is a bevel gear. One end of the dimming adapter rod 3 is connected to the dimming gear 4 via a second bevel gear 7. A second support frame 70 is also provided on the outside of the headlight housing 1 to support the second bevel gear 7. The second bevel gear 7 and the dimming adapter rod 3 are fitted with internal hexagonal sockets for easy disassembly and assembly. Simultaneously, the end of the first bevel gear 6 furthest from the dimming gear 4 also has an internal hexagonal structure. Thus, an external hexagonal wrench or similar tool can be used to directly apply force to the first bevel gear 6, causing the dimming gear 4 to rotate, which in turn rotates the second bevel gear 7 and the dimming adapter rod 3. The dimming adapter rod 3 then drives the dimming assembly 2 to dim. This structure in this embodiment, using the dimming gear 4 as the adapter structure, combined with the transmission engagement of the first bevel gear 6 and the second bevel gear 7, allows the dimming path to adapt to multi-angle and large-angle requirements. External manual dimming is not limited by angle, and dimming is quick, efficient, and convenient. At the same time, while ensuring normal dimming, it saves space occupied by the adapter structure, can be adapted to more headlight shapes, and can meet the needs of smaller spaces.
