Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1~4, in the embodiment of the present invention, a kind of car belt retracting assembly, comprising: coiler 1, guiding
Roller 2, fixed disk 3, mounting rack 5, brake assemblies 6, the coiler 1 are fixed on mounting rack 5, are fixedly mounted by mounting rack 5
In the B column or C column of automobile frame, the guide roller 2 is arranged two groups, and is parallel to each other and is in same level, safety
Band 4 issues from coiler 1 and successively around two guide roller 2, is pierced by out of automobile frame;The wherein shaft of a guide roller 2
On be fixedly installed with fixed disk 3, the fixed disk 3 is in the form of annular discs, can rotate synchronously with guide roller 2, and the brake assemblies 6 wrap
Include: brake disc 61, thread spindle 62 and guide rod 63, the brake disc 61 are discoid, center setting and the cooperation of thread spindle 62
Threaded hole, through in the threaded hole, described 62 one end of thread spindle is rotatably arranged on mounting rack 5 thread spindle 62, the other end with
The shaft of guide roller 2 connects, and the guide rod 63 is fixed on mounting rack 5, and through the through-hole that 61 bottom end of brake disc is arranged in,
Thread spindle 62 is driven to rotate when guide roller 2 rotates, so that brake disc 61 is to the direction translational close to or far from fixed disk 3, Gu
It is provided with protrusion 31 on the end face of 3 relative brake disk 61 of price fixing, two groups of moveable buffer stoppers 611 are set in brake disc 61, and
Position is corresponding with protrusion 31, and the buffer stopper 611 is arranged in the slot of brake disc 61, and buffer stopper 611 is far from protrusion 31
Guide post 612 is set on one end, pressure spring 613 is set on the guide post 612, when fierce hit occurs for vehicle, safety belt 4 is quickly drawn
It is dynamic that guide roller 2 is driven to rotate, while brake disc 61 is mobile to 3 direction of fixed disk, when protrusion 31 is contacted with buffer stopper 611, benefit
Make 611 pairs of protrusions 31 of buffer stopper cause to limit with the elastic force of pressure spring 613, play a buffer function, to be generated to safety belt 4
Braking effect offsets the kinetic energy of Partial security band 4, and during guide roller 2 continues to rotate, brake disc 61 continues to fixed disk 3
It is close, so that the braking effect enhancing that 611 pairs of protrusions 31 of buffer stopper generate, until balancing out the kinetic energy of safety belt 4 makes its stopping,
In this process, protrusion 31 is generated multiple buffer-braking to safety belt 4 by multiple braking effect, i.e., in the stretching that collides
Safety belt is realized during safety belt repeatedly to buffer, and the pressure between safety belt and human body is divided into multistage and is offset, is kept away
The problem of final strong impaction of human body is damaged to safety belt is exempted from;Further, since in usually brake disc 61 far from fixed disk
3, normal use safety belt will not be impacted, only safety belt pull-out is played after exceeding certain length after automobile collides
Braking action.
Such as Fig. 5, buffer stopper 61 is set as arc-shaped with raised 31 opposite end faces and smoothly transits, and to stretch safety belt 4
When 2 rotation direction of guide roller be positive direction, the end face of buffer stopper 61 is gradually decreased along positive direction height, i.e., when colliding,
Raised 31 current buffer blocks 61 movement, and from its it is high-end moved to bottom end, in this way end of braking rear guide roller 2 can be in coiler
It is rotated backward under 1 return force function, brake disc 61 is made to return to original position.
Since when colliding, safety belt 4 has driving effect to guide roller 2, and realized between the two using friction therebetween
Synchronous Transmission, therefore in order to improve frictional force, it avoids occurring to slide relatively, ceramic layer of sand 21 is arranged in the surface of guide roller 2.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
