Abstract

The utility model relates to a vehicle bumper, and the utility model is mainly relates to a single swing arm overtaking collision protection device for vehicles when a small car collides the truck tail of a large truck. In the utility model, the lower parts of two single swing arms are respectively provided with an elastic clamping plate, and the elastic clamping plate is composed of a front plate and two elastic plates which extend backwardly at both sides, and inclination supporters whose lower ends are connected together are arranged on the front plates of the elastic clamping plates. Thus, the utility model has the advantages of reliable overtaking collision protection, and the utility model has the advantages that the guard protection device can not be shaken during the driving time of the vehicle.

Description

Elastic clip formula simple pendulum arm protects the device that knocks into the back

The utility model relates to a kind of anticollision device for vehicle, mainly refers to the anti-device that knocks into the back of simple pendulum arm of the small passenger car collision truck tailstock.

At present, the most of highway of China is still small passenger car and truck all-purpose road, small passenger car knocks into the back truck and collides bottom the truck, accident easily gets into an accident, common truck afterbody is provided with fixing plane baffle plate frame, knocks into the back to prevent small passenger car, but has little effect, and when running into the road surface higher obstacle being arranged, the baffle plate frame can take place broken.Though many failure-freies protection device that knocks into the back recently appears,, vehicle rocking of swing arm often occur when the travels down of injustice or speed change are travelled, both produced noise, and is fragile again.

In view of this, present purpose of the present utility model provides a kind of elastic clip formula simple pendulum arm and protects the device that knocks into the back, and the diagonal ligament lower end of stretching out on girder is provided with Elastic clamping plate and clamps the simple pendulum arm bottom, and tube frame is not rocked.

The purpose of this utility model realizes like this: it comprises two simple pendulum arms and a tube frame, wherein tube frame is to be fused by upper and lower horizontal endless tube, VERTICAL TUBE and the folded pipe of many groups, it is characterized in that: all be provided with Elastic clamping plate in two simple pendulum arm bottoms, this Elastic clamping plate is to be made of two elastic plates that stretch a header board and two rear flank thereof, is provided with the diagonal ligament that is connected with its lower end again on the header board of Elastic clamping plate.

Above-mentioned two elastic plate cantilever ends are the ends that curve inwardly.

Owing to adopt such scheme: anti-knocking into the back impacted reliably, and protective device can not rock during car travelled, and protective device also can lift automatically when meeting obstacle simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments is shown clever figure.

The A-A generalized section of Fig. 2 the utility model exemplary embodiments Fig. 1.

Among the figure: 1, simple pendulum arm 2, tube frame 21, last horizontal endless tube 22, following horizontal endless tube 23, VERTICAL TUBE 24, folded pipe 3, diagonal ligament 4, Elastic clamping plate 41, header board 42, elastic plate

Present embodiment comprises two simple pendulum arms 1, one tube frame 2, two diagonal ligaments 3 and two Elastic clamping plate plates 4, as shown in Figure 1, wherein: the upper end of two simple pendulum arms 1 (as: channel-section steel section bar) is articulated in truck girder tail end, and back, lower end stationary pipes framework 2, this tube frame 2 is by last horizontal endless tube 21, following horizontal endless tube 22, VERTICAL TUBE 23 and folded pipe 24 fuse, wherein go up, following horizontal

endless tube

21,22 is identical, and many VERTICAL TUBE 23 separately connect, following horizontal

endless tube

21,22 1 sides, the folded pipe of many again groups 24 compartment of terrains are connected to, following horizontal endless tube 21, before 22, between rear side, with the rigidity of reinforced pipe framework 2, belong to prior art.

Two diagonal ligaments 3 (as: square frame section bar) upper end is fixed on truck girder lower end, and the lower end connects the header board 41 of Elastic clamping plate 4.

Two cartridge clip plates 4 are to be made of two elastic plates 42 that stretch a header board 41 and two rear flank thereof, these Elastic clamping plate 4 cantilever ends are the ends that curve inwardly, as shown in Figure 2, two elastic plates 42 clamp simple pendulum arm 1 bottom (front and both sides) ordinatedly, and the front of simple pendulum arm 1 is against the header board 41 of Elastic clamping plate 4, keeping during truck travels, in speed change (comprising startups, parking) and when jolting, simple pendulum arm 1 and tube frame 2 do not rock, and avoid noise generation and member to damage.

The principle of work of present embodiment is as follows:

When the car that knocks into the back collides the tube frame 2 of truck afterbody below, impulsive force is absorbed by VERTICAL TUBE 23, upper and lower horizontal

endless tube

21,22 and folded pipe 24, and the damage that alleviates car is when big as if impulsive force, two

simple pendulum arms

1 and 3 flexural deformations of two diagonal ligaments can stop that still car creeps into the truck bottom; When truck runs into obstacle to overtake, two simple pendulum arms 1 can be thrown off Elastic clamping plate 4 and be gone up (anticlockwise direction on Fig. 1) swing backward, through behind the obstacle, tube frame 2 recovers automatically below the truck tail end because of conducting oneself with dignity again and simple pendulum arm 1 enters clamping in the Elastic clamping plate 4.

Claims

1, a kind of elastic clip formula simple pendulum arm protection device that knocks into the back comprises two simple pendulum arms (1) and a tube frame (2), wherein tube frame (2) is to be fused by upper and lower horizontal endless tube (21), (22), VERTICAL TUBE (23) and many folded pipes of group (24), it is characterized in that: all be provided with Elastic clamping plate (4) in two simple pendulum arms (1) bottom, this Elastic clamping plate (4) is to be made of two elastic plates (42) that stretch a header board (41) and two rear flank thereof, is provided with the diagonal ligament (3) that is connected with its lower end again on the header board (41) of Elastic clamping plate (4).

2, protect the device that knocks into the back by the described elastic clip formula of claim 1 simple pendulum arm, it is characterized in that: above-mentioned two elastic plates (42) cantilever end is the end that curves inwardly.
