The invention discloses a vehicle model identifier with an alarm and a shock absorber. The distance between a vehicle and the vehicle model identifier can be detected by using the vehicle model identifier. When the vehicle comes, a light curtain sensor and a double-piezoelectric film sensor in the vehicle model identifier are started, and the vehicle is identified, so that energy is saved; meanwhile, a distance sensor can detect the distance between the vehicle, a person or other objects and the vehicle model identifier, and an alarm is given; the vehicle model identifier can be effectively prevented from being scraped by the objects, and an antitheft function is achieved; moreover, a trapezoidal base is arranged at the bottom of a shell on which the light curtain sensor is mounted, and a rubber gasket is arranged inside the trapezoidal base, so that vibration caused by running of a large-sized heavy vehicle is reduced favorably, and the light curtain sensor can reliably and stably work; meanwhile, a bulged circular truncated cone is arranged on an upper bottom plate, the contact area between a supporting rod and the base is increased, and the supporting strength of the supporting rod is improved favorably.
