[0002] At present, automobile lightweighting is of great significance to automobile fuel saving, emission reduction, performance improvement, and healthy development of the automobile industry. It is an important direction for the development of modern automobile industry technology. Lightweighting has become an inevitable trend for building a conservation-oriented society and sustainable development. The support frame of the vehicle-mounted gas cylinder is a device used to fix and support the liquefied natural gas cylinder on the car. The design and structure of this frame are crucial to ensure the stability and safety of the gas cylinder. The traditional vehicle-mounted gas cylinder support frame has a pair of saddles for each saddle bracket, which makes the weight of the entire vehicle-mounted gas cylinder support frame very large, resulting in a heavy load on the car. The use of ordinary materials is not conducive to movement, installation and use. The support frame is heavy and will consume more fuel when installed on the car. Utility Model Content
