Description
Technical field
The utility model is related to passive safety feature technical field, the safety belt retracting of specifically a kind of low noise
Device.
Background technology
With the rapid development of automobile industry, people require also to be continuously improved to the safety of automobile and comfort.
Safety belt is the critical component of vehicle passive safety.Vehicle induction mechanism in safety belt, usually mainly by sensitive pawl,
Sensitive ball, sensitive seat, sensitive pin bank are into sensitive ball is freely movable in the space between sensitive pawl and sensitive seat.Work as emergency
During generation, sensitive pawl is lifted in sensitive ball rolling, the lockable mechanism of safety belt is triggered, so as to fulfill the protection to occupant.
However automobile is under steam, especially when by roughness pavement, sensitive club generates with body oscillating
Bounce, and sensitive pawl, sensitive seat collide with periphery, generate noise, influence the comfortable sexual experience of user.
In the prior art, typically using increase blimp or sensitive pawl and sensitive seat TPE thermoplastic elastomer (TPE)s
The methods of material or other softer modified plastics reduces noise.But both modes all Shortcomings：The former increases
Cost is added, the latter's noise reduction is limited, and due to the use of TPE thermoplastic elastic materials or softer plastic, causes part strong
Degree is reduced, is easily deformed, size is unstable, and there are the risks of safety belt locking disabler.
Therefore, it is necessary to design a kind of seat belt retractor of low noise, noise is generated when reducing Che Gan mechanisms in vibration
While, cost of implementation is cheap, target stable and reliable for performance.
Invention content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of seat belt retractor of low noise,
While generating noise when reducing Che Gan mechanisms in vibration, cost of implementation is cheap, target stable and reliable for performance.
In order to achieve the above object, the utility model is a kind of seat belt retractor of low noise, including U-shaped frame, winding
Cylinder, lockable mechanism, Che Gan mechanisms and with sense mechanism, belt reel is arranged on U-shaped frame, the end of belt reel be equipped with lockable mechanism and
Band sense mechanism, the ratchet pawl sensitive with Che Gan mechanisms with sense mechanism are engaged or are detached, it is characterised in that：Che Gan mechanisms include quick
Feel pawl, metal magnetic sensitivity ball, magnetic sensitive seat and sensitivity to sell, between the groove and sensitive pawl bottom groove on magnetic sensitive seat
Space in be placed with metal magnetic sensitivity ball.
Using sensitive pin connection between the sensitive pawl and sensitive seat.
The magnetic sensitive seat includes magnetic bases and sensitive pedestal, and magnetic bottom is equipped in the groove on sensitive pedestal
Seat, metal magnetic sensitivity ball are placed on magnetic bases.
The utility model compared with the existing technology, is coordinated using magnetic sensitive seat and metal magnetic sensitivity ball, is meeting method
While rule require, the bounce that metal magnetic sensitivity ball is generated in vibration is limited, it is low so as to reduce the noise that vibration generates
It is of low cost, it is stable and reliable for performance.
Description of the drawings
Fig. 1 is the mounting structure schematic diagram of the utility model.
Fig. 2 is the explosive view of the utility model.
Specific embodiment
The utility model is described further in conjunction with attached drawing.
Referring to Fig. 1, Fig. 2, the utility model is a kind of seat belt retractor of low noise, including U-shaped frame, belt reel, lock
Locking mechanism, Che Gan mechanisms and with sense mechanism, belt reel 20 is arranged on U-shaped frame 10, and the end of belt reel 20 is equipped with lockable mechanism
210 and with sense mechanism 330, band feel mechanism 330 the pawl 311 sensitive with Che Gan mechanisms 310 of ratchet 331 engage or detach.Vehicle sense
Mechanism 310 includes sensitive pawl 311, metal magnetic sensitivity ball 312, magnetic sensitive seat 315 and sensitive pin 313, sensitive pawl 311 with it is quick
It is connected between sense seat 315 using sensitive pin 313, sensitive pawl 311 can be rotated around sensitive pin 313.Groove on magnetic sensitive seat 315
It is placed with metal magnetic sensitivity ball 312 in space between sensitive 311 bottom groove of pawl, metal magnetic sensitivity ball 312 can be
It is freely rolled in the groove of magnetic sensitive seat 315.
Magnetic sensitive seat 315 includes magnetic bases 318 and sensitive pedestal 316, and magnetic is equipped in the groove on sensitive pedestal 316
Property pedestal 318, metal magnetic sensitivity ball 312 are placed on magnetic bases 318.Magnetic bases 318 are noted by having magnetic powder
It moulds, magnetic bases 318 are assembled after being separately formed with sensitive pedestal 316.Magnetic bases 318 and sensitive pedestal 316 select
With POM acetal resin materials, the integral strength of Che Gan mechanisms 310 can guarantee.
Upon occurrence of an emergency situation, vehicle occur acceleration, deceleration, it is inclined in the case of, due to metal magnetic sensitivity
The inertia of ball 312, metal magnetic sensitivity ball 312 roll on magnetic bases 318, generate relative displacement, metal magnetic sensitivity ball
312 lift sensitive pawl 311, the head of sensitive pawl 311 and the tooth engagement of ratchet 331, trigger the lockable mechanism 210 of safety belt,
Crevis 211 being pressed into the ratchet of U-shaped frame 10, realize the locking of belt reel 20, ribbon cannot pull out, so as to fulfill
Protection to occupant.Herein, since sensitive pedestal 316 and sensitive pawl 311 are preferably POM acetal resin materials, ensure vehicle sense
The integral strength of mechanism 310, so as to better ensure the reliability of locking.
Under automobile normal running, when by roughness pavement, pass through the magnetic limitation metal magnetic of magnetic bases 318
Sensitive ball 312 generates bounce in vibration, reduce metal magnetic sensitivity ball 312 and magnetic sensitive seat 315 and sensitive pawl 311 it
Between shock, so as to achieve the purpose that reduce noise.
