Abstract

The invention discloses a gear and screw connecting type heavy vehicle rear protective device and aims at overcoming the problems that an existing heavy vehicle rear protective device is large in mass, high in cost and complex in structure and is not suitable for promotion. The gear and screw connecting type heavy vehicle rear protective device includes a helical gear fixing frame, a platform frame, a driving motor, a controller, a screw rod, a bearing supporting seat, a supporting rod and a bumper. The driving motor is installed at the left ends of two of upper end transverse beams in the platform frame. The controller is fixedly installed on the internal side of the third upper end transverse beam in the platform frame. The controller is connected with the driving motor through an electric wire. The helical gear fixing frame is installed on two of the upper end transverse beams on the right side of the driving motor. The bearing supporting seat is installed at the rear end of an upper end longitudinal beam through a bolt. The left end of the screw rod is connected with the output end of the driving motor through a flange plate. The right end of the screw rod is installed on the bearing supporting seat by using a bearing after passing through the helical gear fixing frame. The upper end of the supporting rod is connected with a first helical gear element and a second helical gear element which are in the helical gear fixing frame in a threaded mode. The lower end of the supporting rod is fixedly connected with the front end face of the bumper.

Description

technical field [0001] The invention relates to a rear protection device applied to vehicles, more precisely, the invention relates to a gear screw connection type heavy-duty vehicle rear protection device. Background technique [0002] At present, the research on the rear protective device of heavy-duty vehicles at home and abroad is mainly based on the purely mechanical rear protective device, that is, the rear protective device is directly rigidly connected with the rear bumper. This purely rigidly connected rear protective device not only affects the passability of heavy vehicles, but also will be damaged due to the vehicle running on bad roads, so that its protective function cannot be guaranteed. In addition, because the rear protective device of heavy vehicles is relatively high from the ground, when vehicles such as cars or SUVs collide with heavy vehicles, it is easy for vehicles such as cars or SUVs to "drill" into the rear suspension of heavy vehicles, which canno...
