Embodiment Construction

[0015] The present invention as figure 1 , 2 shown.

[0016] The rear protection device of the truck, the lower part of the tail of the frame 6 is provided with a symmetrical fixed bracket 1 downward, the fixed bracket 1 is provided with a connecting bracket 3 through the rotating shaft 1 2, and the connecting bracket 3 is provided with a transverse member 5 through the rotating shaft 2 4, wherein the horizontal Member 5 is triangular.

[0017] The first rotating shaft 2 and the second rotating shaft 4 are provided with a bead type locking mechanism.

[0018] The use of the bead-type locking mechanism makes the rotating shaft not only limited and locked when it rotates.

[0019] When the truck is running normally during use, such as figure 1 As shown, the connecting bracket 3 is lifted up to the upper maximum limit of the locking mechanism 2 through the second rotating shaft and locked, and then the bottom surface of the cross member 5 is adjusted to face the rear of the v...

Abstract

The invention provides a truck back protection device. Symmetrical fixing supports are arranged on the lower portion of the tail of a frame downwardly, a connecting support is arranged on each fixing support through a first rotating shaft, and each connecting support is provided with a triangular transverse member through a second rotating shaft. A collision bead type locking mechanism is arranged in each of the first and second rotating shafts. Due to the fact that the fixing supports and the connecting supports are connected through the rotating shafts and then each transverse member is connected and extends to the tail to function as a fender, drilling-in type collision of the tail of a truck is blocked; due to the action of the rotating shafts, when the truck parks, the transverse members can be wound to the bottom of rear wheels and function as stow-wood by the aid of the triangle stability principle to support the truck and prevent the truck from sliding on a slope, and safety in truck parking on ramps is ensured.

Description

technical field [0001] The invention relates to the technical field related to the automobile industry, in particular to a protective device for the rear of a truck. Background technique [0002] In order to reduce the damage to the vehicle when a small car collides with a truck and minimize personal injury, national regulations require that a truck with a total mass greater than 3500kg must be equipped with a rear protective device. Prevent drill-in collisions. [0003] At present, the rear protection devices of trucks sold in China generally use guardrails, which only meet the requirements for rear protection of vehicles. Contents of the invention [0004] In order to allow the rear guard of the truck not only to protect but also to prevent slopes, the present invention proposes the rear guard of the truck. [0005] For this reason, the technical solution of the present invention is that the protective device at the rear of the truck includes a vehicle frame, which is ...
