Technical Field

[0001] The utility model relates to a lamp housing of an automobile lamp, in particular to a lamp housing structure of an automobile headlamp with a shockproof function, belonging to the technical field of lamp housings of automobile headlamps. Background Art

[0002] With the rapid development of the automobile industry, people's requirements for automobile safety performance are getting higher and higher. As an important safety component, the stability and reliability of automobile headlights are directly related to the driving safety of drivers.

[0003] In order to maintain the aesthetic appearance of the car, existing car manufacturers often use a partial clamping structure to control the gap between the front bumper and the car headlight to improve the stability of the lampshade. However, this partial clamping structure is not only complex in design, but also has a small area formed by the lamp housing installation point, making installation difficult.

[0004] A car headlight bracket and a car with announcement number CN218400367U include a bracket body, the bracket body having a first edge and a second edge arranged relatively to each other, a plurality of clamping parts arranged in sequence along the second edge, and a positioning rib arranged close to one side of the second edge. The utility model connects the headlight and the front bumper respectively through the mounting part and the clamping part on the body to optimize the gap and surface difference in the matching gap area between the front bumper and the headlight, thereby improving the exquisiteness of the appearance of the whole vehicle. The positioning rib design on the bracket body also increases the area formed by the mounting point between the bracket and the lamp housing, thereby improving the positioning stability of the car headlight bracket in the width direction of the whole vehicle.

[0005] In the above technical solution, by setting the positioning ribs on the bracket body, the area formed by the mounting point between the bracket body and the lamp housing can be increased, thereby improving the stability of the positioning of the automobile headlight bracket in the width direction of the entire vehicle. However, in actual use, especially when the car is driving for a long time or driving on bumpy roads, the vibration of the vehicle itself and the vibration generated by the road surface are superimposed on each other, which may produce a large vibration amplitude. This long-term vibration can easily lead to damage to the bulb key components inside the automobile headlight housing. For this reason, we provide a car headlight housing structure with a shockproof function. Utility Model Content

[0026] Working principle:

[0027] First, through the characteristics of the first spring 18 connected below the support baffle 15, the first spring 18 can provide a certain buffer when the support baffle 15 is subjected to vibration impact, thereby reducing the direct impact of the vibration on the bulb, which helps to extend the service life of the bulb and reduce the risk of damage to the bulb caused by vibration. The other end of the first spring 18 is fixed to the bottom of the first limiting hole 12, which can be limited;

[0028] Secondly, the fixing buckle 10 and the latch teeth 17 are engaged with each other, ensuring that the installation opening protection cover 9 can be firmly installed on the bulb installation opening 8, and when the bulb needs to be installed or maintained, the fixing buckle 10 is unlocked from the top of the latch teeth 17, and the installation opening protection cover 9 is twisted to make the limiting slider 20 slide in the slide groove 13, and the limiting pressing block 19 is lifted up by the rebound force of the first spring 18 under the supporting baffle 15. After being lifted up, the installation opening protection cover 9 can be opened, so that the bulb can be replaced or inspected conveniently. The wire tube protection shell 11 is used to protect the wires or wire tubes connected to the bulb to prevent them from being damaged by the external environment;

[0029] Then, when the installation opening protective cover 9 is closed, the installation opening protective cover 9 is twisted to make the limiting slider 20 slide in the slide groove 13 and slide to the card slot 14. The limiting slider 20 is pushed to the card slot 14 through the cooperation between the support baffle 15 and the first spring 18, which can improve the stability between the bulb installation opening 8 and the installation opening protective cover 9;

[0030] Finally, the bulb mounting hole 16 can limit the bulb in the center of the support baffle 15 and the first spring 18, so that the bulb is evenly shock-absorbed in the bulb mounting port 8, thereby increasing the service life. The sealing edge 3 between the front lampshade 1 and the lampshade rear shell 2 ensures a tight connection between the two, while the first fixing frame 4, the second fixing frame 5 and the third fixing frame 6 enhance the stability of the entire lamp housing structure, and are fixed to the vehicle body or other components through the fixing frame limiting hole 7, further improving the stability of the lamp housing.
