The coiler that specific embodiment of the present invention provides, including bracket assembly 1, mandrel 2, vehicle induction device 3, retainer
4, external toothing 5, control loop 6, balance wheel 7, interior pawl, band sense pawl 8 and vehicle sense pawl 9.Retainer 4 and external toothing 5 are installed on successively
1 inside of bracket assembly, control loop 6 are installed on 1 outside of bracket assembly, and control loop 6, retainer 4 and external toothing 5 are coaxial with mandrel 2
Setting, 4 periphery of retainer are provided with outer ratchet, and 4 inner circumferential of retainer is provided with interior ratchet, and 5 periphery of external toothing is also correspondingly arranged on ratchet.
The side that definition is equipped with retainer 4 is 1 inside of bracket assembly, and the side for being equipped with control loop 6 is 1 outside of bracket assembly.
When mandrel 2 is rotated relative to retainer 4 and the external toothing 5, the interior pawl can stretch out and above-mentioned bracket assembly 1
Locking, 6 periphery of control loop include anti-lock section 61 of large-calibred belt sense, path band sense locking section 62, anti-lock section 63 of major diameter vehicle sense and path
Vehicle sense locking section 64, the diameter of major diameter section are more than the diameter of path section.One end of vehicle sense pawl 9 offsets with vehicle induction device 3, vehicle sense
The other end of pawl 9 and the periphery of control loop 6 offset, with sense pawl 8 and vehicle sense pawl 9 hinged with bracket assembly 1 respectively,
Middle part with sense pawl 8 is provided with the protrusion to offset with 6 periphery of control loop, while being provided with spring, can push vehicle sense pawl 9
With band sense pawl 8 close to control loop 6.
When safety belt needs anti-lock, i.e. the length of safety belt extraction at this time is not up to predetermined length, and expression personnel are taking out
During going out safety belt, therefore locking is not needed, anti-lock section 61 of the large-calibred belt sense of control loop 6 at this time and anti-lock section of major diameter vehicle sense
63 offset with band sense pawl 8 and vehicle sense pawl 9 respectively, are relatively large in diameter for anti-lock section due to major diameter, make band sense pawl 8 far from retainer 4,
And detached with outer ratchet, and vehicle sense pawl 9 pushes so that vehicle induction device 3 is detached with the periphery of external toothing 5, mandrel 2 is relative to lock
Circle 4 and the external toothing 5 are static, that is, during extracting safety belt out, while band moving mandrel 2 rotates, and retainer 4 and external toothing 5
Also it can rotate synchronously, no matter quickly extract safety belt or vehicle deceleration out, interior pawl will not stretch out and 1 locking of bracket assembly, reality
It is existing anti-lock.
Safety belt needs the length of safety belt extraction at this time when locking to reach predetermined length, and expression personnel have fastened safety
Band, it is therefore desirable to which locking, during extracting safety belt out before, mandrel 2 persistently rotates, and makes control loop by transmission device
6 rotate therewith, and under the action of transmission device, and after safety belt extracts predetermined length out, control loop 6 can also turn to predetermined angle
It spends, the path band sense locking section 62 of control loop 6 offsets with the protrusion with sense pawl 8 at this time, path vehicle sense locking section 64 and vehicle sense
Pawl 9 offsets, and since path locking section diameter is smaller, makes band sense pawl 8 close to retainer 4, band sense pawl 8 under the action of the spring
With outer ratchet locking, vehicle sense pawl 9 lifts, and when vehicle deceleration reaches predetermined value, vehicle induction device 3 is no longer limited, with external tooth
The periphery locking of circle 5, safety belt extraction acceleration is when reaching predetermined value, balance wheel 7 lift with interior ratchet locking, make 2 phase of mandrel
Retainer 4 and external toothing 5 are rotated.I.e. retainer 4 is no longer rotated with external toothing 5 at this time, and safety belt continues extraction can band moving mandrel 2
Lasting rotation, make interior pawl stretch out and with 1 locking of bracket assembly, realize the locking of safety belt.
Specifically, vehicle deceleration is not up to 0.45g, will not locking, vehicle deceleration reaches 0.45g, vehicle sense locking, peace
Full band extraction acceleration is less than 0.8g, will not locking, safety belt extracts acceleration out and is greater than or equal to 2.0g, band sense locking.
The case where there is effectively anti-lock measure, avoid still having locking when normally extracting safety belt out simultaneously, conveniently make
With reduction number of parts simplifies structure, reduces assembly difficulty and cost.
In the coiler that specific embodiment of the present invention provides, vehicle induction device 3 includes being installed on bracket assembly 1
Vehicle sense seat 31 is provided with gravitation ball 32 and vehicle sense arm 33 in vehicle sense seat 31, and one end and the gravitation ball 32 of vehicle sense arm 33 offset, vehicle sense
The other end of arm 33 offsets with vehicle sense pawl 9, and when vehicle deceleration reaches predetermined value, gravitation ball 32 pushes vehicle sense arm 33 and external tooth
The periphery locking of circle 5.
Wherein, one end that mandrel 2 stretches out on the outside of bracket assembly 1 is provided with external tooth, and 6 inner circumferential of control loop is provided with internal tooth,
Transmission device specially engages the duplex-gear of external tooth and internal tooth respectively, is realized and is rotated synchronously by gear structure, and mandrel 2 passes through axis
It covers across and is articulated with bracket assembly 1.Other modes can also be used and realize synchronous rotation, in the scope of protection of the utility model
Within.
On the basis of the coiler that above-mentioned each specific implementation mode provides, 1 periphery of bracket assembly is provided perpendicular to prop up
The mounting hole of frame assembly 1.In order to improve the stability of control loop 6, the band sense driving that 6 periphery of control loop packet is set gradually in an axial direction
Face and vehicle sense drive surface include anti-lock section 61 of large-calibred belt sense being sequentially arranged in the circumferential direction. and path band sense locking section with sense drive surface
62, vehicle sense drive surface includes anti-lock section 63 of major diameter vehicle sense being sequentially arranged in the circumferential direction. and path vehicle sense locking section 64.By control loop 6
Periphery vertical profile be two annulars, two annular peripheries are respectively band sense drive surface and vehicle sense drive surface, then respectively will be with sense
Drive surface and vehicle sense drive surface are divided into major diameter section and path section, form four drive surfaces in 6 periphery of control loop, adjust band at this time
The position of the protrusion of sense pawl 8 and vehicle sense pawl 9 is contacted with corresponding drive surface, also can according to circumstances adjust setting for drive surface
Mode is set, both is within the protection scope of the present invention.
Bracket assembly 1 includes the holder of the locking closure and steel material of plastic cement material, and locking closure is installed on holder, and locking closure is used for
Connecting components, holder be used for interior pawl locking, improve enough rigidity.
