The invention provides a vehicle-mounted CNG cylinder protection mechanism which comprises a CNG cylinder, buffering assemblies, a limiting assembly and an anti-impact assembly, a first protection shell and a second protection shell are arranged on the outer wall of the CNG cylinder, the buffering assemblies are arranged in the protection shells, the first protection shell is connected with the limiting assembly, the anti-impact assembly is connected between the two protection shells, and each buffering assembly comprises a sliding rod. The sliding rod is fixedly connected with the protective shells and sleeved with two buffering sliding blocks, a reset spring is fixedly connected between the two buffering sliding blocks, buffering rods are hinged to the buffering sliding blocks, the two buffering rods are hinged to the fixing ring, the buffering sliding block in the first protective shell is connected with a limiting assembly, the limiting assembly comprises a hinge rod, and the hinge rod is connected with a first limiting rod. The first limiting rod is connected with a first limiting plate, the buffering sliding block is fixedly connected with a second limiting rod, and the second limiting rod penetrates through the top end of the protection shell and is connected with a second limiting plate. According to the vehicle-mounted CNG cylinder protection mechanism, fatigue damage is reduced, the buffering force is enhanced, and the fixing stability is enhanced.
