Abstract
The utility model relates to a novel rear protective device system which can meet the requirements of different car types, has multiple functions and also has an important characteristic that the device has the buffering function and can well protect a car. The rear protective device system is convenient to manufacture and also has the advantages of simple structure, light weight, low cost and the like. The rear protective device system comprises a fixing device fixedly connected with a frame, the fixing device is connected with a rotary stretching device, and the rotary stretching device is connected with a cross rod.
Description
Technical field
The utility model relates to the novel protective device system afterwards that a kind of heavy motor vehicle is used, and is mainly used in non-tractor truck vehicle.
Background technology
For reducing the generation of major traffic accidents, the particularly generation of the rear-end collision of car and heavy duty truck, the standard rules and regulations heavy duty truck must install additional the back protective device, to reduce because of knocking into the back to the infringement of car, install the departure angle that the back protective system certainly will reduce vehicle additional, vehicle is just higher to the requirement of road like this.And the different vehicle ' height of different automobile types, requiring the different back protective system of coupling, this just requires to design multiple back protective device, has both increased the kind of back protective device, has also increased productive costs.
Summary of the invention
The technical problems to be solved in the utility model: non-tractor truck vehicle, cause the variation of car load height because of the difference of car load rear overhang length or suspension height or tire size, and then require the different back protective device system of coupling, to satisfy the requirement of whole-car parameterses such as different departure angles and ground Clearance, be in the technical design process or on mould development or production assembly technology, all to be a kind of great waste like this.
In order to solve the problems of the technologies described above; the utility model proposes a kind of novel protective device system afterwards; to satisfy different vehicles; accomplishing to use one more; and this device also has an important characteristic to have buffer action exactly; can better play a protective role to car, the utility model also has simple in structure, easily manufactured, in light weight, low cost and other advantages in addition.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel protective device system afterwards, it comprises the anchor fitting that is connected with vehicle frame, and anchor fitting is connected with the rotary extension device, and the rotary extension device is connected with cross bar.
Described anchor fitting is a pair of fixed support that vehicle frame is connected, and each fixed support is connected with corresponding rotary extension device.
Described rotary extension device comprises swinging strut and is connected telescope support with swinging strut, and wherein swinging strut is connected with fixed support, and telescope support then is connected with cross bar.
Described swinging strut is adjusted in 0 °-90 °.
Described telescope support is adjusted in the 0mm-90mm scope.
The beneficial effects of the utility model are: automobile is in fitting process, vehicle rear overhang length is inconsistent, if adopt a kind of rear overhang certainly will influence the departure angle of car load, make the crossing ability variation of vehicle, and adopt the back protective device of this kind structure, can be by the suitable increase departure angle of rotation back protective device support, if this moment, the back protective device exceeded the car load rear overhang, can also be by the be connected bracket holes of change with the cross bar assembly, shorten the transverse distance of whole device, satisfy laws and regulations requirement.If different suspensions or tire are adorned in client's choosing, cause the car load height change, also can be by regulating the requirement that this device satisfies differing heights, different departure angle, different transverse distances.
Description of drawings
Fig. 1 is a scheme of installation of the present utility model;
Fig. 2 is the block diagram of Fig. 1.
Wherein: 1, fixed support, 2, swinging strut, 3, telescope support, 4, cross bar, 5, vehicle frame.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, Fig. 2, it comprises a pair of fixed support 1 that is fixed on the vehicle frame 5, and each fixed support 1 flexibly connects with corresponding swinging strut 2, and 2 of swinging struts are connected with telescope support 3 accordingly, and telescope support 3 is connected with cross bar 4.
In use:
1. the front and back scalable realizes up and down.Change with realizing the continuity angle of swinging strut 2 in 0 ° of-90 ° of scope being connected of fixed support 1 by regulating swinging strut 2.Can realize the discountinuity variable in distance of cross bar assembly 0mm-90mm on flexible direction by regulating telescope support 3, the variation by this both direction realizes adjusting before and after the back protective device up and down, just really accomplishes usefulness more than one.
2. rear-end collision when taking place in the realization of buffer action, if impact force F reaches certain value, the rotation of certain angle will take place around fixed support 1 in swinging strut 2, when rotating to bottom, tie bolt will reach capacity, can not continue rotation this moment, this rotary course is a buffering course, avoids vehicle generation hard collision, reduces the injury to vehicle and chaufeur.
Adjustable+buffering back protective device system that the utility model adopts not only can reduce the kind of back protective device, and reduce the exploitation of mould and attractive in appearancely firmly reduced the deadweight and the cost of car load, be the first-selection of modern heavy-duty automobile.
Claims (5)
1. a novel protective device system afterwards is characterized in that it comprises the anchor fitting that is connected with vehicle frame, and anchor fitting is connected with the rotary extension device, and the rotary extension device is connected with cross bar.
2. novel protective device system afterwards as claimed in claim 1 is characterized in that described anchor fitting is a pair of fixed support that vehicle frame is connected, and each fixed support is connected with corresponding rotary extension device.
3. novel back as claimed in claim 1 or 2 protective device system is characterized in that, described rotary extension device comprises swinging strut and be connected telescope support with swinging strut, and wherein swinging strut is connected with fixed support, and telescope support then is connected with cross bar.
4. novel protective device system afterwards as claimed in claim 3 is characterized in that described swinging strut is adjusted in 0 °-90 °.
5. novel protective device system afterwards as claimed in claim 3 is characterized in that described telescope support is adjusted in the 0mm-90mm scope.
