Description
Technical field
The utility model relates to car belt technical field, particularly relates to a kind of prefastening 3 safety strap.
Background technology
When a fault occurs, forward, seat backward for people for seat belt pretensioners, if now safety strap is excessively loose, occupant easily skids off below safety strap, or people encountered air bag but now safety strap due to tensioning surplus excessive and fail to tighten in time, this all may cause occupant's major injuries.
Firmly beforehand means of the prior art is all the mode adopting indirect transfer, and the sensitive time is long, and induction efficiency is poor, and the Occupation coefficient that result in safety strap is not high.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of prefastening 3 safety strap, simple and compact for structure, and velocity response mode more directly effectively, improves the warning degree of driver and crew to snapping safety strap, ensure that making full use of of safety strap.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of prefastening 3 safety strap, comprise: taking-up device, speed sensor and pretension control unit, the speed sensor that described taking-up device comprises housing, is arranged on the axle drive shaft of enclosure interior and installs on the driving shaft, described pretension control unit comprises revolving wheel, elastic draw bar and connecting rope, one end of described connecting rope connects on the driving shaft, the other end is connected on revolving wheel, and described elastic draw bar is connected with axle drive shaft.
In the utility model preferred embodiment, for be electrically connected between described speed sensor and taking-up device.
In the utility model preferred embodiment, the sensitive time of described speed sensor is 0.01s ~ 0.1s.
In the utility model preferred embodiment, described elastic draw bar is arranged for abutting with between axle drive shaft.
In the utility model preferred embodiment, described axle drive shaft is also provided with an antiskid pad.
The beneficial effects of the utility model are: the utility model prefastening 3 safety belt structures are simply compact, and velocity response mode more directly effectively, improves the warning degree of driver and crew to snapping safety strap, ensure that making full use of of safety strap.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of prefastening of the present utility model 3 safety strap one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, housing, and 2, axle drive shaft, 3, speed sensor, 4, revolving wheel, 5, elastic draw bar, 6, connecting rope.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of prefastening 3 safety strap, comprising: taking-up device, speed sensor 3 and pretension control unit, the speed sensor 3 that described taking-up device comprises housing 1, is arranged on the axle drive shaft 2 of housing 1 inside and installs on driving shaft 2.
Described pretension control unit comprises revolving wheel 4, elastic draw bar 5 and connecting rope 6, one end of described connecting rope 6 connects on driving shaft 2, the other end is connected on revolving wheel 4, and described elastic draw bar 5 is connected with axle drive shaft 2, and described elastic draw bar 5 is arranged for abutting with between axle drive shaft 2.
For to be electrically connected between described speed sensor 3 and taking-up device, the sensitive time of described speed sensor 3 is 0.01s ~ 0.1s.The moving velocity of automobile is once higher than specified value, and namely speed sensor 3 receives speed signal, is sent to axle drive shaft 2 simultaneously, starts seat belt pre-tensioning pattern.
Speed sensor 3 controls firmly beforehand means, can allow driver and crew more direct feeling to the protective effect of safety strap, improve the warning degree of driver and crew to snapping safety strap, ensure that making full use of of safety strap.
Described axle drive shaft 2 is also provided with an antiskid pad, reduces the friction force of connecting rope 6, ensure that pretension control unit pretensioning capacity rapidly and efficiently.
When the moving velocity of automobile exceedes specified value, speed sensor 3 receives speed signal, simultaneously by signal transmission to axle drive shaft 2, the action of axle drive shaft 2 rotating band dynamic elasticity pull bar 5, simultaneously revolving wheel 4 starts and tightens up safety strap by connecting rope 6.
The beneficial effect of the utility model prefastening 3 safety strap is:
Simple and compact for structure, velocity response mode more directly effectively, improves the warning degree of driver and crew to snapping safety strap, ensure that making full use of of safety strap.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
