Description
Technical field
The invention belongs to automobile collision preventing technical field of structures, and in particular to a kind of rear protecting reinforcement structure of truck.
Background technique
The tailstock of lorry is generally fitted with rear defence protection structure, for prevent to knock into the back traffic accident when car pierce
Lorry rear end bottom, the driver's cabin of car can be seriously damaged when car pierces lorry tail end bottom, to can make to driver
At larger danger, thus safeguard structure can be avoided and cause bigger injury.Existing rear defence protection structure generally all includes installation
Frame and collision prevention girders, and mounting rack generally is L-shaped structure, is fixed on vehicle frame because collision prevention girders only pass through mounting rack, and install
Frame is usually bolted on vehicle frame, and overall structural strength is poor, when lorry is by car rear-end, rear defence protection structure by
Shock is easy to cause the vertical section of mounting rack to be bent, and then the car to knock into the back may be made to continue to pierce lorry tail end bottom, makes
The injury of Cheng Geng great, meanwhile, huge impact force also results in bolt fracture, and the junction of mounting rack and vehicle frame is made to cause to damage
It is bad.
Summary of the invention
The present invention is for the poor drawback of rear protecting structural strength, the rear protecting for providing a kind of truck add in the prior art
Strong structure, for reinforcing the stiffening plate of mounting rack, which can be used in preventing on mounting rack the rear protecting structure setting
Vertical section bending, to promote the structural strength of rear defence protection structure.
Goal of the invention of the invention is achieved through the following technical solutions: a kind of rear protecting reinforcement structure of truck,
Including the mounting rack being fixedly mounted on straight chassis frame, which includes the orthogonal vertical section being fixedly connected and level
Section, vertical section and horizontal segment constitute L-shaped structure, and the vertical section is fixedly connected with straight chassis frame, vertically solid on the horizontal segment
Surely it is connected with protection crossbeam；It is fixed between the mounting rack and straight chassis frame, compartment straight beam for preventing vertical section from being bent
Stiffening plate, the stiffening plate, protection crossbeam be located at the front and rear sides of vertical section, and the stiffening plate is towards the side of vertical section
While being fixedly connected with the bending plate vertical with itself, which is bonded and is fixedly connected with the front side of vertical section.Above scheme
In, it prevents vertical section from being bent by stiffening plate, to enhance the structural strength of vertical section, also vertical section can be prevented straight with vehicle frame
The junction of beam generates destruction, and then enhances the overall structural strength of rear defence protection structure, is able to ascend the anti-impact of rear defence protection structure
Performance is hit, prevents car from piercing lorry tail end bottom in rear-end collision.The bending plate is by stiffening plate main part bent
At, it is easy to process, and bending plate can determine according to actual needs relative to the overbending direction of stiffening plate.
Preferably, being detachably fixed connection between the stiffening plate and compartment straight beam.In existing some lorries, vehicle

It is achieved a fixed connection between bending plate on plate by bolt.The setting of vertical section epipleural, horizontal segment upper side edge setting energy
It is enough to promote vertical section, the structural strength of horizontal segment respectively, and then the structural strength of mounting rack is promoted, and the side plate on front side of vertical section
Cooperate with the bending plate in stiffening plate, be capable of increasing contact area, be easily installed screw, thus realize vertical section and stiffening plate it
Between be detachably fixed connection.
Preferably, stiffener is fixedly connected between the vertical section and horizontal segment, the stiffening plate and stiffener point
Not Wei Yu vertical section front and rear sides.The setting of stiffener is able to ascend the structural strength of vertical section Yu horizontal segment junction, into
And promote the structural strength of mounting rack entirety.
Preferably, the length direction of the stiffener and the length direction angulation of horizontal segment are 45 °.
Preferably, the stiffener is bent into L-shaped structure by plate.The bending resistance and structure of single plate are strong
Spend poor, and plate is bent into L-shaped structure and is able to ascend bending resistance and structural strength, and then promotes the counter-bending of stiffener
Performance and structural strength, the final structural strength for promoting junction between vertical section and horizontal segment.
Compared with prior art, the invention has the following advantages: the present invention is able to ascend by the setting of stiffening plate
The bending resistance of vertical section on mounting rack, and then the structural strength of mounting rack is promoted, it is able to bear mounting rack, protection crossbeam
Stronger impact force, car pierces lorry bottom when avoiding lorry and car that rear-end collision occurs, and promotes security performance.Meanwhile
The installation of stiffening plate will not influence the installation of U bolt between lorry compartment straight beam itself and straight chassis frame, and stiffening plate also can
Play the function that fixedly connected part is equivalent to the fixed function between compartment straight beam and straight chassis frame, prevent compartment straight beam with
Opposite sliding between straight chassis frame.
