Abstract
The utility model relates to a connect firm trailer back thick stick, including two support arms, anticollision roof beam, the support arm is located and welds with trailer frame junction has the reinforcing plate, and the cross-section of anticollision roof beam is the polygon, and the polygon is located the vertical setting in limit and the bottom of trailer rear side and is equipped with the chamfer, and the support arm middle part is dashed there is the flanging hole that is used for strengthening and subtract the weight effect, and anticollision roof beam both ends all are equipped with the rubber shrouding. The surface of the rear side of the anti-collision beam is a vertical plane, and the contact surface of a rear vehicle and the anti-collision beam is in surface contact when collision occurs, so that the transmission of collision force is facilitated, and the accident loss is reduced; the chamfer at the bottom of the rear side of the anti-collision beam increases the departure angle of the vehicle, so that the vehicle is more convenient to use; the setting up of reinforcing plate has increased the thickness of support arm and trailer frame junction, and when taking place the lateral part collision, the shearing force bearing capacity of the junction of support arm and trailer is bigger, connects more firmly, has avoided connecting bolt to break off to reduce the guard action's of back thick stick the condition.
Description
Technical Field
The utility model relates to a vehicle safety facility technical field especially relates to a connect firm trailer back thick stick.
Background
The anti-collision beam of thick stick generally adopts round tube formula or square tube formula behind current trailer, and two kinds of modes mainly have following defect: firstly, the contact surface of a rear vehicle and the circular tube type anti-collision beam is in line contact during collision, so that the transmission of collision force is not facilitated, and the accident loss is easily expanded; secondly, in order to ensure the strength, the width of the square tube type anti-collision beam is large, so that the departure angle of the vehicle is small, and the square tube type anti-collision beam is inconvenient to use; thirdly, when a side collision occurs, the joint of the rear bumper and the trailer is subjected to a large shearing force, and the connecting bolt is easily broken, so that the protective effect of the rear bumper is reduced.
Disclosure of Invention
The utility model discloses aim at solving prior art's not enough, and provide one kind and connect firm trailer back thick stick.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
the utility model provides a connect thick stick behind firm trailer, including two support arms, the anticollision roof beam, support arm top and trailer frame afterbody fixed connection, the support arm is located and welds the reinforcing plate with trailer frame junction, two support arms are the vertical setting in platelike and place plane, two support arms are parallel with the direction of travel of trailer, the support arm top sets up to trailer front side slope, support arm bottom and anticollision roof beam fixed connection, the cross-section of anticollision roof beam is the polygon, the polygon is located the vertical setting in limit and the bottom of trailer rear side and is equipped with the chamfer, the support arm middle part is dashed there is the flanging hole that is used for strengthening and subtracts the weight effect, the anticollision roof beam both ends all are equipped with the rubber.
Preferably, each support arm is fixedly connected with the trailer frame through four bolts.
Preferably, the back side and the top of the supporting arm are provided with flanges for reinforcement.
Preferably, the hollow setting of anticollision roof beam, the cross-section of anticollision roof beam all is equipped with the chamfer for quadrangle and front side and rear side.
The utility model has the advantages that: the surface of the rear side of the anti-collision beam is a vertical plane, and the contact surface of a rear vehicle and the anti-collision beam is in surface contact when collision occurs, so that the transmission of collision force is facilitated, and the accident loss is reduced; the chamfer at the bottom of the rear side of the anti-collision beam increases the departure angle of the vehicle, so that the vehicle is more convenient to use; the setting up of reinforcing plate has increased the thickness of support arm and trailer frame junction, and when taking place the lateral part collision, the shearing force bearing capacity of the junction of support arm and trailer is bigger, connects more firmly, has avoided connecting bolt to break off to reduce the guard action's of back thick stick the condition.

fig. 4 is a left side view of an embodiment of the present invention;
in the figure: 1-a support arm; 2-an anti-collision beam; 3-a reinforcing plate; 4-flanging holes; 5-rubber closing plate;
the following detailed description will be made in conjunction with embodiments of the present invention with reference to the accompanying drawings.
Detailed Description
The invention will be further explained with reference to the following figures and examples:
as shown in the figure, a connect firm trailer back thick stick, including two support arms 1, anticollision roof beam 2, 1 top of support arm and trailer frame afterbody fixed connection, support arm 1 is located and welds with trailer frame junction has reinforcing plate 3, two support arms 1 are the vertical setting in platelike and place plane, two support arms 1 are parallel with the direction of travel of trailer, support arm 1 top inclines to the trailer front side and sets up, 1 bottom of support arm and 2 fixed connection of anticollision roof beam, the cross-section of anticollision roof beam 2 is the polygon, the polygon is located the vertical setting in limit and the bottom of trailer rear side and is equipped with the chamfer, 1 middle part of support arm is dashed there is the flanging hole 4 that is used for strengthening and subtract the heavy effect, 2 both ends of anticollision roof beam all are equipped with rubber.
Preferably, each support arm 1 is fixedly connected with the trailer frame through four bolts.
Preferably, the back side and the top of the support arm 1 are provided with flanges for reinforcement.
Preferably, crashproof roof beam 2 is hollow to be set up, and crashproof roof beam 2's cross-section all is equipped with the chamfer for quadrangle and front side and rear side.
When the utility model is used, the surface of the anti-collision beam 2 facing the rear side is a vertical plane, and the contact surface of the rear vehicle and the anti-collision beam 2 is in surface contact when collision happens, thus being beneficial to the transmission of collision force and reducing accident loss; the chamfer at the bottom of the rear side of the anti-collision beam 2 increases the departure angle of a vehicle, so that the vehicle is more convenient to use, and compared with the existing square tube type rear bumper, the departure angle is increased from the original 35 degrees to 39 degrees by taking the existing vehicle of a certain type as an example; the thickness of support arm 1 with the trailer frame junction has been increased in setting up of reinforcing plate 3, and when the lateral part collision took place, the shearing force bearing capacity of the junction of support arm 1 and trailer was bigger, and it is more firm to connect, has avoided connecting bolt to break off to reduce the guard action's of back thick stick the condition.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above embodiments, and various improvements made by the method concept and technical solution of the present invention or directly applied to other occasions without improvement are all within the protection scope of the present invention.
