Description
Technical field
The utility model is related to the accessory of automotive seat, specifically a kind of disc spring guide type locking system.
Background technology
Currently, there are many type of angle adjusting device for reclining seat of automoble both at home and abroad, it is round automotive seat to be normally applied more
Angle demodulator, such as " the built-in circle automobile of disclosed Patent No. " ZL200620069427.8 " on Chinese patent website
Seat angle adjustment ", it includes involucrum, disk, small tooth plate, circular tooth disk, lock tooth torsional spring, lock tooth shifting block and central shaft；Circle
Disk is installed together with circular tooth disk tight fit, and involucrum is sleeved on the outer circle surrounding of circular tooth disk and disk, and lock tooth shifting block close-fitting exists
On central shaft, one end of small tooth plate is engaged with circular tooth disk gear, the other end and lock tooth shifting block cam engagement.But it is this existing
The angle adjusting device for reclining seat of automoble of technology haves the shortcomings that following：Since disk and involucrum have radially in this configuration
Gap, therefore, when automotive seat adjuster when in use, i.e., in the angle of adjusting automobile seat back, disk and involucrum
Between can collide or relatively rotate, then will produce noise in operation；In addition, this touching can make between disk and involucrum by
So that piece surface is generated abrasion in friction, and then influence the normal use of recliner, shortens its service life.
102001296 B of notification number CN the invention discloses a kind of angle regulating device for seat of vehicle, including shell (1), have it is interior
The circular tooth disk (7) of cavity, the disk fixed seat (3) with inner cavity, central shaft (4) and locking system, the circular tooth disk (7)
Outer circle with ring gear (10), and circular tooth disk (7) is linked in disk fixed seat (3), makes the inner cavity and circle of circular tooth disk (7)
The inner cavity of disk fixed seat (3) constitutes the cavity that an energy houses locking system, and the shell (1) is linked in disk fixed seat
(3) on periphery, the locking system is a tight fit on central shaft (4), the shell (1) and disk fixed seat (3) it
Between be equipped with rolling member.After using the above structure, make to ensure the two by rolling member between disk fixed seat and shell
Between the stationarity that mutually moves, to avoid the noise generated by touching；Also extend the use of angle regulating device for seat of vehicle simultaneously
Service life.The patented technology has the following disadvantages：1, poorly sealed close, because there is the presence of the mounting hole (11) of disc spring free end,
It directly results in pitch-dark part and dust is easily accessible intracavitary to cause the blunt phenomenon of card, make its failure；2 be to use ball (2) in ring
Movement, all inconvenient in manufacture and installation in this way in slot (12), when ball (2) blocks blunt failure；3 be using central shaft (4) and
Cam (5) precision-fit, failure is just will appear when firmly slightly larger.
A kind of recliners for automotive seat of 102717732 B of notification number CN, include circular tooth disk with ring gear,
Disc seat and locking system constitute the inner cavity for housing locking system, the lock between the circular tooth disk and disc seat
Locking apparatus includes cam, disc spring and two locking tooth plates, and described locking tooth plate one end is equipped with and the circular tooth disk ring gear phase
The teeth of engagement, disk base inner surface are equipped with the sliding slot being slidably matched in it for locking tooth plate, and the cam is circumferentially
If there are four convex block, it is equipped with and the matched locking groove of convex block on two locking tooth plates；The center of the cam, which is equipped with, to be used
In with the matched through-hole of square column, and extended downwardly out at the center of the lower face of the cam for matched with disc spring
Fang platform, the square hole fitting that the disc spring is equipped with through middle part are installed on the outer wall of the fang platform, the free end of the disc spring
In the aperture that the disc seat is equipped with.The balance and stability of cam be more preferable, locking good reliability.
Absolute cooperation, while the system of mold are needed for cam (3) and cooperation locking tooth plate (4) in the patented technology
It is high to make requirement, serious forgiveness is low, while central shaft runs through from outside, is susceptible to gap, also can be to spring and cam and locking tooth
The cooperation of plate generates deviation, and the gap that this deviation directly results in seat adjusting increases.
202225758 U of notification number CN disclose a kind of locking system of angle regulating device for seat of vehicle, including cam (4) and
Disc spring (2), the cam (4) are equipped with pillar (4.2) with cam (4) integral molding and vertically arranged, institute
The one end for the disc spring (2) stated is resisted against on the pillar (4.2).In actual use, since pillar and cam are one
Body formula is molding, so intensity higher, is not susceptible to deform and drop off, good reliability, can guarantee angle regulating device for seat of vehicle just
It is often used.
The disc spring in locking system in above-mentioned 3 patented technologies realizes locking by pillar on cam or boss, but
It is that disc spring is easy bias under twisting force, to make its torsion change, so as to cause failure.
Invention content
The utility model reduces gap in order to make angle regulating device for seat of vehicle reach sealing effect, also for system
Make with it is easy for installation, have and also to be disc spring and be oriented to and moved in certain space, spy proposes a kind of disc spring guide type
Locking system.
The technical solution of the utility model is a kind of disc spring guide type locking system thus, including fixed seat, fixed seat to
End face is externally provided with multiple recess, and be recessed interior filling butter, and being staggered to be recessed into end face is equipped with multiple boss, shape between multiple boss
