The present disclosure relates to a vehicle lamp, and particularly relates to an optical assembly mounting structure. The present disclosure also relates to a vehicle lamp lighting device, a vehicle lamp and a vehicle.
Vehicle lamps exhibit a significant trend towards miniaturization at present, which requires a more simplified and integrated structure of a lamp module, and a more compact arrangement of components of the lamp module.
With miniaturization and flattening of the styling of the vehicle lamp, there are increasingly demands on small vehicle lamp lighting devices in the market. A small vehicle lamp lighting device generally refers to a vehicle lamp in which the greatest one of a length, width and height of a lighting device is less than or equal to 130 mm, wherein the smaller one of a length and width of a light-emitting surface of a lens or an optical element with other light-emitting forms is less than or equal to 20 mm. Some small vehicle lamps require the greatest one of the length, width and height of the lighting device to be less than or equal to 110 mm, and require the smaller one of the length and width of the light-emitting surface of the light-emitting optical element to be less than or equal to 10 mm. The small vehicle lamp lighting device has more compact components and has higher requirements on position accuracy of optical components.
The existing optical assembly mounting structure has not been able to adapt to the demands of the development trend for miniaturization of vehicle lamps today, and there is no accurate and reliable overall mounting structure for optical assemblies of a miniaturized lighting device, and there is an urgent need in the market for an optical assembly mounting structure that is simplified, reliable and highly accurate in positioning for a miniaturized vehicle lamp.
The technical problem to be solved by the present disclosure is to provide an optical assembly mounting structure, which is highly accurate in positioning, simplified in mounting, and reliable. The technical problem further to be solved by the present disclosure is to provide a vehicle lamp lighting device, which has simple structure, high optical assembly positioning precision, and reliable mounting.
The technical problem further to be solved by the present disclosure is to provide a vehicle lamp, which is small in size and accurate and stable in lighting shape position.
The technical problem to be solved by the present disclosure is to provide a vehicle having a vehicle lamp with small size and accurate and stable lighting shape.

A rear end of the primary optical element is mounted on the radiator by fitting of the rear fitting portions and the C-shaped limiting structures, and a front end of the primary optical element is mounted on the lens mount by fitting of the front fitting portions and the primary element limiting frames.
Preferably, two primary element limiting frames are provided, and the two primary element limiting frames are disposed on two sides of the lens mount separately. Support grooves are formed in rear ends of the primary element limiting frames relative to positions of the front fitting portions, and the front fitting portions are mounted on the support grooves. In this preferred technical solution, stable fitting between the front end of the primary optical element and the lens mount may be formed by fitting of the support grooves in the primary element limiting frames on the two sides and the front fitting portions on the mounting portions of two sides of the primary optical element.
Further preferably, each support groove includes an on-groove contact surface, an in-groove contact surface and an under-groove contact surface.

The front upper fitting surface is in contact with the on-groove contact surface, the front-end fitting surface is in contact with the in-groove contact surface, and the front lower fitting surface is in contact with the under-groove contact surface. By this preferred technical solution, stable fitting and accurate positioning may be formed between the front fitting portions and the support grooves, such that mounting stability and mounting precision of the front end of the primary optical element on the lens mount are higher.
Further, each front fitting portion further includes a side stopper that is positioned on the outsides the primary element limiting frame and is in contact with the primary element limiting frame. By this preferred technical solution, the front fitting portion may be positioned in a left-right direction, further improving the positioning accuracy of the primary optical element.
Preferably, an outer side of each C-shaped limiting structure includes an upper circuit board limiting surface, an outer circuit board limiting surface and a lower circuit board limiting surface. Each C-shaped positioning groove includes a positioning groove upper portion, a positioning groove side portion and a positioning groove lower portion. The upper circuit board limiting surface is in contact with an upper side wall of the positioning groove upper portion, the outer circuit board limiting surface is in contact with an outer side wall of the positioning groove side portion, and the lower circuit board limiting surface is in contact with a lower side wall of the positioning groove lower portion. In this preferred technical solution, the circuit board is positioned by the three fitting surfaces between the outer side surface of each C-shaped positioning groove and the outer side surface of each C-shaped positioning structure, so that the positioning stability and the positioning accuracy are higher.
Further preferably, the radiator is provided with a circuit board contact surface. The C-shaped limiting structures are disposed on the circuit board contact surface, and the circuit board is in contact with the circuit board contact surface. In this preferred technical solution, due to contact between the circuit board and the circuit board contact surface, on the one hand, the circuit board and a light source mounted on the circuit board are in close contact with the radiator, thereby improving the heat dissipation effect of the light source. On the other hand, backward positioning of the circuit board is formed, improving the positioning accuracy of the circuit board and the light source mounted on the circuit board.
Preferably, an inner side of each C-shaped limiting structure includes an upper element limiting surface, an outer element limiting surface and a lower element limiting surface. Each rear fitting portion includes a rear upper fitting surface, a rear-side fitting surface, a rear lower fitting surface, and a rear-end fitting surface. The rear upper fitting surface is in contact with the upper element limiting surface, and the rear-side fitting surface is in contact with the outer element limiting surface. The rear lower fitting surface is in contact with the lower element limiting surface, and the rear-end fitting surface is in contact with the circuit board. By this preferred technical solution, multi-directional positioning of the rear fitting portion is formed, stable fitting of the primary optical element and the radiator is formed, and positioning accuracy between the rear end of the primary optical element and the circuit board and between the rear end of the primary optical element and the radiator is effectively improved.
Preferably, the lens mount includes a lens mounting opening at which a lens is fixedly connected. In this preferred technical solution, the mounting position of the lens on the lens mount is fixed by fitting between the lens mounting opening and the lens, thereby defining the relative position between the lens and the primary optical element and between lens and the light source, and guaranteeing the positioning accuracy between the lens and the primary optical element.
Further preferably, the lens and the lens mount are integrally formed. The positioning accuracy and the stability of the position of the lens are further guaranteed by this preferred technical solution.
