Description

Technical Field

[0001] The utility model belongs to the technical field of turn signal lamps, and in particular relates to a rearview mirror turn signal lamp capable of automatically adjusting brightness. Background Art

[0002] In the current automotive industry, automatically adjustable brightness rearview mirror turn signals have become a widely used safety configuration. This design integrates the turn signal indicator into the rearview mirror housing, which is not only beautiful, but also automatically controls the brightness of the turn signal according to the intensity of the external light during the day or at night, improving the visibility of the vehicle when changing lanes or turning. However, after long-term use, this design has also exposed some problems. The most prominent problem is the risk of dust accumulation and falling. Over time, dust, dirt and other tiny particles will gradually penetrate into the connection between the turn signal and the rearview mirror housing, which not only affects the brightness and clarity of the light, but may also cause the connection between the components to become loose.

[0003] If the rearview mirror turn signal is not fixed firmly enough, it will directly affect its use effect and safety performance. First, the loose turn signal may produce abnormal noise during driving, affecting the driving experience. Secondly, the angle of the light may be offset, reducing the effectiveness of the turn signal and increasing the risk of traffic accidents. More seriously, if it is not fixed properly, the turn signal may fall off during high-speed driving or in bad weather conditions, which will not only cause property damage, but also endanger the safety of other road users.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0014] Preferably, a spring is provided on the return rod, the spring is sleeved on the positioning rod, and the spring abuts against the fixed sleeve. The design of the spring ensures that the release sleeve will not contact the one-way sheet at ordinary times.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] (1) The mounting mechanism of the utility model realizes the stable mounting of the rearview mirror turn signal lamp through the ingenious coordination of the reflector housing, the light strip, the fixing sleeve, the fixing spring, the pressure plate, the compression spring, the fixing ring and the clamping block. The fixing spring is pressed on the reflector housing to provide a preliminary fixing force for the light strip. The fixing ring is pressed into the telescopic hole of the light strip through the action of the compression spring and the pressure plate, further enhancing the fixing effect of the light strip. The clamping block cooperates with the one-way sheet in the fixing sleeve to form a one-way limit to prevent the light strip from accidentally loosening. This multiple fixing method greatly improves the stability and reliability of the rearview mirror turn signal lamp and effectively solves the problem of dust falling after long-term use.

[0017] (2) The receiving mechanism of the utility model is composed of a receiving sleeve and a receiving spring, which provides additional support and buffering for the entire installation system. The receiving sleeve is slidably connected to the fixed sleeve, and multiple clamping blocks abut against the receiving sleeve to form a stable supporting structure. The receiving spring connects the receiving sleeve and the fixed sleeve to provide a return force for the system, so that the clamping state remains stable. This design not only increases the stability of the overall structure, but also absorbs vibration to a certain extent, thereby extending the service life of the equipment. At the same time, the existence of the receiving mechanism also provides the necessary buffer space for the operation of the unlocking mechanism, making the operation of the entire system smoother.

[0018] (3) The unlocking mechanism of the utility model includes an unlocking sleeve, a push rod, a push plate, a handle and an adjusting bolt, which facilitate the disassembly of the rearview mirror turn signal lamp. By pushing the push rod, the unlocking sleeve and the clamping block can slide downward synchronously, thereby releasing the clamping connection between the one-way plate and the annular groove. The unlocking sleeve can also keep the one-way plate in an expanded state to ensure complete separation from the annular groove. The design of the adjusting bolt allows the user to accurately control the unlocking process to avoid damage caused by improper operation. This design not only facilitates maintenance and replacement operations, but also greatly reduces the risk of damage to other components during operation, thereby improving the maintainability and service life of the product.
