Description

Technical Field

[0001] The utility model relates to the technical field of headlamp production, in particular to an openable decorative ring structure. Background Art

[0002] With the continuous progress of automobile production technology and the continuous improvement of automobile quality, people have higher requirements for every detail of automobiles. The combined headlamp is the headlamp with the highest requirements, the most complex structure, and the greatest difficulty in design and manufacturing among headlamps. It not only needs to meet the safety requirements in regulations but also satisfy some other requirements. For example, the appearance should be integrated with the overall appearance of the automobile, be beautiful and practical, and meet the requirements of aerodynamics. Therefore, the current headlamp design technology is also changing with each passing day with the development of the automobile industry. The decorative ring is an important part of the combined headlamp, located between the reflector and the light distribution lens, and plays the role of decoration and beauty as well as reflecting part of the light in the lamp system. Due to the diverse designs of automotive combined headlamps, the decorative ring is no exception. However, there are certain technical problems in the existing technology: First, the rotation of one pair or multiple pairs of decorative ring bodies will occupy a relatively large space in the headlamp cavity; Second, when these decorative ring bodies are applied to the periphery of the lens module, the space between the lamp cover, the housing and the main decorative ring remains unchanged. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the utility model provides a pressing plate fixing structure to solve the problems.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An openable decorative ring structure, comprising a stepping telescopic motor, a transmission rod, a movable decorative ring and a fixed decorative ring, characterized in that: the stepping telescopic motor and the fixed decorative ring are fixedly installed in the lamp housing, the transmission rod is provided with a first ball head, the movable decorative ring is provided with a ball bowl corresponding to the first ball head of the transmission rod, and is provided with track grooves on both sides, the fixed decorative ring is provided with a second ball head corresponding to the track grooves of the movable decorative ring, one end of the transmission rod is fixedly connected to the stepping telescopic motor, and the other end is movably clamped to the ball bowl of the movable decorative ring through the first ball head, and the second ball head of the fixed decorative ring is movably clamped in the track grooves of the movable decorative ring.

[0006] The openable decorative ring structure of the utility model is scientifically designed, reasonable in structure, simple in construction, small in occupied space, convenient to install and use, safe and reliable in function, good in effect, and low in manufacturing cost. Description of the Drawings

[0007] The drawings described herein are used to provide a further understanding of the present application, and constitute a part of the present application. The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation to the present application.

[0012] In the figure: 1 - stepper telescopic motor; 2 - transmission rod; 21 - first ball head; 3 - movable decorative ring; 31 - ball bowl; 32 - track groove; 4 - fixed decorative ring; 41 - second ball head. Specific embodiments

[0013] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the present utility model. In these descriptions, keywords that need to be noted include "movable decorative ring" and "fixed decorative ring", etc. These are only for the convenience of describing the present utility model and simplifying the description, and therefore cannot be construed as limitations on the present utility model.

[0014] As Figure 1 shown, the openable and closable decorative ring structure of the present utility model includes a stepper telescopic motor 1, a transmission rod 2, a movable decorative ring 3 and a fixed decorative ring 4. The stepper telescopic motor 1 and the fixed decorative ring 4 are fixedly installed in the lamp housing. The transmission rod 2 is provided with a first ball head 21. The lower part of the movable decorative ring 3 is provided with a ball bowl 31 corresponding to the first ball head 21 of the transmission rod 2, and both sides are provided with track grooves 32. The fixed decorative ring 4 is provided with a second ball head 41 corresponding to the track grooves 32 of the movable decorative ring 3. One end of the transmission rod 2 is fixedly connected to the stepper telescopic motor 1, and the other end is movably connected (clamped) to the ball bowl 31 of the movable decorative ring 3 through the first ball head 21. The second ball head 41 of the fixed decorative ring 4 is movably connected (clamped) in the track grooves 32 of the movable decorative ring 3. When the present utility model works, the transmission rod 2 is driven by the telescopic movement of the stepper telescopic motor 1, and the movable decorative ring 3 is driven to slide with the second ball head 41 of the fixed decorative ring 4 as a support in the track grooves 32, so that the movable decorative ring 3 swings by a certain amplitude, realizing the partial opening and closing of the main body of the decorative ring. It can cooperate with the lighting shape to complete personalized dynamic design, can also prevent sunlight focusing by rotating to a certain extent, and can also change the air flow circulation space structure between the decorative ring and the lamp shade and the housing, promote the dissipation of fog, and reduce the risk of fog generation.

[0015] The above is only one implementation mode of the present utility model. For those skilled in the art, the present utility model may also have various other implementation modes with changes and variations, which will not be elaborated one by one here. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model are all included within the scope of protection required by the present utility model.
