Further, a protective cover bracket is installed on the lower end of the connecting plate, and a cylindrical wire harness protective cover is installed on the protective cover bracket. Interference between the connecting wire harness and surrounding objects causes the wire harness to be cut off.

Further, a ring-shaped anti-decoupling hook is welded under the first connecting piece, and the RV rope is fixed in the anti-decoupling hook to prevent the RV from falling off due to the bumping of the passenger car.

Further, the anti-collision beam is in a rearward convex arc shape, and the anti-collision beam is set to have a higher supporting strength for the rear impact force.

Further, a reinforced partition is arranged inside the cavity of the anti-collision beam to increase the rigidity and strength of the anti-collision beam.

Further, the connection between the anti-collision beam and the passenger car is bolted, the connecting plate is bolted to the anti-collision beam, the first connecting piece and the protective sleeve bracket are bolted to the connecting plate, and are connected by bolts. Stable and reliable, and easy to disassemble.

Compared with the prior art, the beneficial effects of the utility model are as follows: the length of the connecting structure between the passenger car and the RV can be adjusted according to the different front-end structures of different RVs, so as to ensure a safe distance; Interference between the connecting wire harness and surrounding objects causes the wire harness to be cut off; an anti-decoupling hook is set to fix the RV rope to prevent the RV from falling off due to bumps in the passenger car.
