Description

Technical Field

[0001] The utility model relates to the technical field of car door welcome lights, in particular to a multi-module car door welcome light. Background Technique

[0002] A welcome light is an automotive accessory whose main function is to automatically light up and project onto the ground when the driver and passengers get on and off the car, so as to be beautiful and remind passers-by. When the car door is closed, the welcome light will automatically go out. The welcome light is usually set at the car door position, together with the reading light and the sunroof switch on the car roof. As long as it is turned on once, the welcome light can automatically sense and switch itself on and off. The welcome light is a new type of green light source for vehicles. It irradiates a film through an LED light source, and then presents the image on the film on the irradiated object through the refraction of a lens. The principle of the welcome light is similar to that of a slide projector.

[0003] The welcome lights in the prior art usually can only display one logo pattern or text, while some users need to display multiple logo patterns or texts. In this case, the welcome lights that display a single logo pattern cannot meet their requirements. Moreover, the light spots projected by the commonly used welcome lights at present have obvious color differences, which affect the user experience. Their structures are also relatively large, occupying a large space and being inconvenient for installation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a multi-module car door welcome light, aiming to solve the above technical problems. The utility model adopts two convex lenses and one concave lens to form a lens group, and the two low-dispersion optical glass lenses and one high-dispersion optical glass lens in the imaging group cooperate with each other, which not only effectively eliminates dispersion and other color differences, but also enables the field of view angle of the imaging module to reach 30 - 60 degrees. The utility model has multiple groups of condenser groups, film groups and imaging groups, which can project multiple groups of logo patterns or texts at the same time, can be applied to multiple scenarios, and has high compatibility. The overall structure is compact, occupying less space, and can project multiple patterns onto corresponding multiple independent areas, can adapt to multiple scenarios, and can also effectively eliminate color differences.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A multi-module door welcome light includes a lens barrel. Inside the lens barrel, an imaging group, a film group, and a condenser group are sequentially arranged from the inside to the outside. The three groups are combined into an imaging module. The imaging group includes a first lens, a second lens, and a third lens. The first lens is a convex lens convex towards the object side, the second lens is a concave lens, and the third lens is a plano-convex lens convex towards the image side. The condenser group includes a condenser lens. The film group includes a film tray and a film. The plano-convex lens can adjust the imaging distance. By adjusting the distance between the object and the lens, the imaging position can be changed to adapt to different actual needs.

[0007] Further, both the first lens and the third lens are optical glass lenses with low dispersion, and the second lens is an optical glass lens with high dispersion. The optical glass lenses have good transparency, very high optical refractive index uniformity, and dispersion performance, which can effectively eliminate dispersion and other chromatic aberrations and make the imaging clearer.

[0008] Further, the film tray is arranged between the condenser lens and the imaging group. A light-transmitting hole is provided in the middle of the film tray. The film tray includes an upper film tray and a lower film tray arranged corresponding to each other up and down. A film limiting groove is provided on the bottom surface of the upper film tray. The film is installed in the film limiting groove and is located between the upper film tray and the lower film tray. The setting of the film limiting groove is used to limit the movement of the film and avoid the displacement of the projected image.

[0009] Further, the condenser lens is a biconvex lens. The biconvex lens reduces the total length of the lens, is used for light field correction, corrects the aberration and distortion problems in the optical system, and improves the imaging quality.

[0010] Further, a first washer is provided between the first lens and the second lens, a second washer is provided between the second lens and the third lens, and a third washer is provided between the third lens and the film tray.

[0011] Further, one or more imaging modules are provided. Each imaging module can independently perform imaging projection, and different imaging modules can also interact for imaging projection to achieve the expected imaging effect.

[0012] Further, one or more lens group mounting cavities are provided in the lens barrel. The number of lens group mounting cavities is equal to the number of imaging modules. A positioning and mounting portion extends outward from the outer side of the bottom of the lens barrel, and a positioning and mounting hole is provided on the positioning and mounting portion. The positioning and mounting portion can fix the lens barrel to the bottom of the door.

[0013] Further, a light-transmitting hole is provided at the front end of the lens group installation cavity, and an imaging group installation position and a condenser film installation position are provided in each lens group installation cavity. The imaging group is installed on the imaging group installation position, and the film group and the condenser group are installed on the condenser film installation position.

[0014] Further, a limiting groove is provided on the condenser film installation position, and a correspondingly arranged limiting protrusion is provided on the outer side of the film group. The limiting protrusion is adapted to the limiting groove, which can, on the one hand, play a role in positioning and installing the film group, and on the other hand, effectively limit the rotation of the film group in the lens group installation cavity.

[0015] Further, the field of view angle of the imaging module is 30 - 60 degrees.

[0016] The multi-module door welcome light of the present utility model has the following beneficial effects:

[0017] 1. In the multi-module door welcome light of the present utility model, one or more groups of the condenser group, the film group and the imaging group can be provided, that is, the required number of groups can be set according to needs. In this way, a pattern can be projected, or multiple groups of logo patterns or characters can be projected simultaneously, which can be applicable to multiple scenarios, has high compatibility, and low cost, solving the problem in the prior art that the projection lamp can only be used in a single scenario and has poor compatibility due to a single welcome mode.

[0018] 2. In the multi-module door welcome light of the present utility model, the imaging module is combined through the first lens, the second lens and the third lens. Coupled with the cooperation of the two low-dispersion convex lenses and one high-dispersion concave lens of the lens group, the dispersion of the concave lens and the dispersion of the convex lens can compensate each other, thereby eliminating dispersion and other chromatic aberrations, effectively improving the imaging clarity and enhancing the user experience.

[0019] 3. In the multi-module door welcome light of the present utility model, the condenser lens adopts a single double convex lens, which reduces the total length of the lens, making the overall volume of the present utility model smaller and occupying less space.

[0020] 4. In the multi-module door welcome light of the present utility model, the imaging group installation position and the condenser film installation position are provided in the lens group installation cavity for fixing the lens and the film, which can effectively prevent the lens and the film from rotating, making the projection more stable.

[0021] 5. In the multi-module door welcome light of the present utility model, the combination of two convex lenses and one concave lens enables the field of view angle of the lens group to reach 30 - 60 degrees, and the field of view angle of the imaging module can project the imaging onto the ground better.
