Description

CROSS-REFERENCE TO THE RELATED APPLICATIONS The present application claims priority to Application No. 202420022210X, filed with the China National Intellectual Property Administration on January 4, 2024, and entitled "VEHICLE LAMP MODULE AND VEHICLE LAMP", the contents of which are incorporated herein by reference in entirety. TECHNICAL FIELD The present application relates to the technical field of vehicle illumination, and specifically to a vehicle lamp module, a vehicle lamp, and a vehicle. BACKGROUND The vehicle lamp plays a critical role in the vehicle illumination system and vehicle performance. It is a vital component in overall vehicle functionality that must satisfy not only aesthetic requirements but also provide an effective illumination effect. With the rapid development of the automotive industry and the user demand for intelligent driving assistance functions, the adaptive high-beam system has emerged as required. The adaptive high-beam system is an intelligent high-beam control system that is capable of adaptively adjusting the high beam based on road conditions. By turning off or dimming partial high-beam illumination segments, it not only can improve the field of vision of the driver, but also can prevent glare to illuminated objects. However, in the adaptive high-beam system, a plurality of reflecting surfaces needs to be provided. Light emitted from the light source is reflected by different reflecting surfaces to the lens. As different reflecting surfaces are located at varying distances from the focal point of the lens, boundaries of resulting light patterns formed by different reflecting surfaces are not flush, thereby compromising the illumination effect of the vehicle lamp. SUMMARY The present application aims at providing a vehicle lamp module, a vehicle lamp, and a vehicle, to address the above shortcomings in the prior art. The vehicle lamp module includes a light source, and a reflecting element and a lens which are sequentially arranged along a light path. The reflecting element is provided with a plurality of reflecting surfaces corresponding to the light source, such that light emitted by the light source is reflected by the plurality of reflecting surfaces and then emits from the lens to form a plurality of light-pattern units each having a first boundary. The plurality of light-pattern units are combined to form an illumination light pattern of an illumination module. Moreover, by providing side edges of the plurality of reflecting surfaces to form an undulating structure, a plurality of first boundaries in the illumination light pattern are allowed to be flush, so as to address the problem in the prior art-non-leveled boundaries in the illumination light pattern caused by different reflecting surfaces being located at varying distances from a focal point of the lens compromise the illumination effect.
