This utility model relates to an externally mounted three-dimensional illuminated lettering and an automobile, belonging to the technical field of externally mounted illuminated lettering. It includes a base cover and a lampshade, with an installation space between the base cover and the lampshade. A circuit board is housed within the installation space, and an LED module is encapsulated on the circuit board. The inner surface of the lampshade has laser-engraved character boundaries; the area within the character boundaries is a light-transmitting area, and the area outside the character boundaries is an opaque area. Light emitted by the LED module passes through the light-transmitting area. By placing the circuit board and LED module inside the base cover and lampshade, and driving them via an externally located driving circuit through electrical connections, the overall size and height of the lettering are reduced, meeting the requirement that the external protrusion height of the automobile is ≤10mm. The lettering is designed separately and can be assembled externally, saving installation space and offering a high degree of assembly flexibility. Even when not illuminated, the laser-engraved character boundaries still have a three-dimensional effect; when illuminated, the light-transmitting area allows light to pass through, thereby improving the lettering's recognition effect.

The utility model discloses a novel cantilever platform structure based on the lever principle. The novel cantilever platform structure comprises a groove type empty box structure and a rod straining beam plate structure. The groove type empty box structure serves as a basic supporting structure of the whole cantilever platform system, the top of the groove type empty box structure is fixedly connected with the rod system beam plate structure, the rod system beam plate structure extends by a certain length on the two sides of the groove type empty box structure, and the lower portion of the inner side end of the rod system beam plate structure is fixedly connected with a ballasting block to form a ballasting structure and a cantilever structure. The outer edge of a lower foundation of the groove type empty box structure serves as a fulcrum of the whole cantilever platform structure, the dead weight and upper loads of the cantilever platform form power torque, the saddle weight and upper loads of the saddle weight form resistance torque, and the outer side of the rod system beam plate structure extends out of the corbel structure to serve as a supporting arm of the cantilever platform structure. According to the utility model, the splicing width of the platform can be flexibly controlled, and a convenient traffic system in which people and vehicles are separated is formed.
