Description
Technical field
The present invention relates to car belt technical field, a kind of automobile safety belt retractor assembly.
Background technology
Along with the development of auto industry level, people for the level of comfort of automobile, bearing strength, technological level,
Appearance requirement, quality and mobility require more and more higher, seat belt " become driver and the problem of occupant's overriding concern, also
It is one of most important performances such as automobile.Occurring in that the seat belt with coiler at present, coiler is one of important parts,
Being related to the safety of seat belt, but current winder structure design is not reasonable, the security performance of seat belt is the most to be added
By force.
Summary of the invention
For solving the problems referred to above, the purpose of the present invention is to provide a kind of automobile safety belt retractor assembly, solves passenger
In the case of fastening seat belts can freely movable above the waist, and can be by seat belt rolling to coiler.
For achieving the above object, automobile safety belt retractor assembly, including support and mandrel, the two of described mandrel for the present invention
End extends through support, and has the wind spring base plate and locking base plate being engaged with it, at the bottom of described wind spring by toothed disc connection respectively
Being provided with outside on plate and be cased with the core body of wind spring, the other end of described wind spring is fixed on the wind spring lid being connected with wind spring base plate,
Described wind spring base plate interior is provided with the S spring of band slide block, and described locking base plate is provided with the internal gear of S spring card master, institute
Stating locking base plate interior and be additionally provided with car sensor seat and steel ball, described internal gear is internally provided with external gear, and external gear is with interior
Being additionally provided with rotating inertia between gear fast, the fast outer, two ends of described inertia is inserted in external gear, in described internal gear
Portion is also respectively provided with the interior ratchet contacted soon with inertia, and the leaf spring of return, described external gear after inertia rotates soon
Outside be additionally provided with the outer ratchet contacted with car sensor seat and steel ball, described locking base plate is covered with locking lid.
Owing to using above technical scheme:
1. spring reclaims function, has a backrush spring inside coiler, and the ribbon being wound on spool can be made toward reclaiming, so
Ensure that ribbon againsts human body all the time.
2. inclination of vehicle sensing, has a car sensor seat and steel ball inside coiler, can sense the angle of inclination of vehicle from
And by mechanical locking mechanism, wind spring is blocked, ribbon cannot pull out.
3. vehicle sense of acceleration is answered, and shares an induction apparatus, i.e. car sensor seat and steel ball with tilt induction, can sense vehicle and dash forward
So acceleration-deceleration, is blocked spool by mechanical locking mechanism, and ribbon cannot pull out.
4. belt acceleration sensing, collides in an instant, and due to inertia, people can be moved along making ribbon pull out, now ribbon
Acceleration sensing, experiences this change, blocks spool in time, and ribbon cannot pull out.
This most practical advantage and good effect be:
Movable upper body that can be comfortable while driver and crew are effectively protected, has been greatly improved by bus comfortable
Property, and mixed and disorderly seat belt can automatically retract in making car, raising car body is tested.

Detailed description of the invention
As shown in Fig. 1 Fig. 2, automobile safety belt retractor assembly, including support 1 and mandrel 11, the two ends of mandrel 11 are respectively
Run through support 1, and have the wind spring base plate 13 and locking base plate 7 being engaged with it, on wind spring base plate 13 by toothed disc connection respectively
Being provided with outside and be cased with the core body 14 of wind spring 17, the other end of wind spring 17 is fixed on the wind spring 17 being connected with wind spring base plate 13 and covers 12
On, wind spring base plate 13 is internally provided with the S spring 16 of band slide block 15, and locking base plate 7 is provided with the internal gear that S spring 16 card is main
8, locking base plate 7 is internal is additionally provided with car sensor seat and steel ball 9, and internal gear 8 is internally provided with external gear 3, and external gear 3 is with interior
Being additionally provided with rotating inertia fast 4 between gear 8, the outer, two ends of inertia fast 4 is inserted in external gear 3, and internal gear 8 is internal also
It is respectively arranged with fast with the inertia 4 interior ratchets 10 contacted, and the leaf spring 6 of return after inertia fast 4 rotates, external gear 3
Outside is additionally provided with the outer ratchet 5 contacted with car sensor seat and steel ball 9, and locking base plate 7 is covered with locking lid 2.
The operation principle of the present invention: inclination of vehicle senses, and is the inclination angle being sensed car body by car sensor seat and steel ball 9
Degree, touches outer ratchet 5 and blocks external gear 3, and external gear 3 blocks mandrel 11 makes ribbon not extract out, and human body is fixed on the seat；
Vehicle sense of acceleration is answered, and is also the acceleration-deceleration being sensed car body by car sensor seat and steel ball 9, touches outer ratchet 5 and block external tooth
Wheel 3, external gear 3 blocks mandrel 11 makes ribbon not extract out, and human body is fixed on the seat equally；Belt acceleration senses, when
Inertia in coiler fast 4 when ribbon quickly pulls out, under the effect of mandrel 11 rotary centrifugal force, make inertial mass 4 offset,
Ratchet 10 in touching, interior ratchet 10 touches internal gear 8 makes mandrel 11 not rotate, and ribbon can not pull out, fixing for human body present
On chair, leaf spring 6 effect is the device making the fast return of inertia 4, thus releases lockup state, and S spring 16 is the device making mandrel return
Thus release lockup state.
The foregoing is only the schematic detailed description of the invention of the present invention, be not limited to the scope of the present invention.Any
Those skilled in the art, equivalent variations done on the premise of without departing from the design of the present invention and principle and amendment, all
The scope of protection of the invention should be belonged to.
