[0002] The dining car is small, environmentally friendly, economical and low-noise, suitable for the meal delivery needs of cities and factories. It has a simple and elegant appearance and a functional modification design. It is widely used in meal delivery services in large factories, airports, schools, hospitals, hotels and other places. It truly realizes health and environmental protection, comfort and energy saving, and meets the different needs of customers. The dining car is composed of a chassis and a body.
[0003] However, during the long-term use of the existing dining car chassis, the leaf spring ear position will have the problem of insufficient force, resulting in an unstable chassis structure and unable to effectively improve the strength and stability of the leaf spring ear. When the dining car chassis is assembled with wheels or other equipment, the two sides of the dining car chassis are exposed, making it easy to be affected by external environmental factors when it is placed or stops moving, making it easy for it to collide with the two sides of the dining car chassis. At this time, not only the dining car chassis is damaged, but also the dining car chassis and the overall equipment are easily displaced, which requires the user to manually or with the help of external tools to prevent the dining car chassis and the overall equipment from moving. This undoubtedly reduces the safety of the user and the surrounding environment and is inconvenient to use. Therefore, we propose a reinforced dining car chassis with easy-to-use functions, which is urgently needed to be developed. Utility Model Content
