Described sliding rail is that the cross section is the Steel section member of the thin-walled strip of doorframe shape; Above the sliding rail, along axis, long limit, be provided with the perforation of the rivet hole corresponding matching of the rivet hole of the upper bracket of described lockset, lower carriage and with the pilot hole position of the lower carriage of lockset and the through hole of size correspondent equal;
Described trapped orbit is the flute profile of crimping in the cross section is, the Steel section member of thin-walled strip; The trench bottom of trapped orbit along axis, long limit, is provided with some being replaced by circular port and mounting hole and arranges the lockhole that constitutes; The arrangement mode of lockhole is that a circular port, mounting hole, another circular port, replacing of another mounting hole are arranged; Wherein, mounting hole is two circular port path lengths, the Long Circle hole that circular aperture is wide; The pitch-row of lockhole is the distance in the center of circle of the center of circle of circular port and adjacent mounting hole circular arc, and promptly the distance in mounting hole two end circular arc centers of circle also is a pitch-row; The aperture of lockhole and pitch-row equate with the aperture and the pitch-row of the pilot hole of described lower carriage.
Mutual alignment and annexation
Spring base be fixed on upper bracket above, upper bracket be positioned at sliding rail doorframe shape above, lower carriage be positioned at sliding rail doorframe shape below, pass the rivet hole of upper bracket, the perforation of sliding rail, the rivet hole riveted of lower carriage with rivet and connect as one; In the chamber that the above part of the back-up ring step of pin surrounds between upper bracket and sliding rail, in the chamber that the following part of the back-up ring step of pin surrounds between sliding rail and lower carriage, the lower end that pin is provided with the guiding chamfering is passed down through the through hole of sliding rail, the pilot hole of lower carriage passes lower carriage downwards; The pusher dog of key tool claw-plate inserts the upper bracket from the side that the upper bracket of lockset is provided with linking arm, the pusher dog liner under the back-up ring step of pin and above the sliding rail between; The wherein side that the end of non-cap head of axle of having strong market potential passes the lockset upper bracket is provided with the pin shaft hole of the linking arm of hook, passes claw-plate again and wherein passes behind the hinge hole of hinge hole, torsion spring, the claw-plate opposite side of a side, and the key tool is linked to each other with lockset; One end of torsion spring and the hook of lockset upper bracket collude stumbles, and the other end and claw-plate collude stumbles; Sliding rail slide to insert in the trapped orbit, passes wherein three in the lower end of five pins of lockset lower carriage downwards, inserts at random in the lockhole of trapped orbit bottom land, and the bottom land retaining of remaining two tracks that then are fixed is between two adjacent lockholes.
Operating principle
External force is pulled the sled handle that key tool claw-plate is with sleeve downwards, the pusher dog of claw-plate upwards holds up five pins, and three pins that insert in the trapped orbit bottom land lockhole are also held up the lockset release simultaneously, sliding rail can move forward and backward along trapped orbit under the effect of external force;
Unclamp the sled handle of key tool claw-plate, resetted by the pusher dog of torsion spring effect claw-plate downwards, the lockset pin is moved down by the effect of spring, wherein three in the lower end of five pins, insert at random in the lockhole of trapped orbit bottom land, remaining two pins then are fixed the bottom land retaining of track between two adjacent lockholes; The lockset locking, sliding rail promptly is locked on the trapped orbit;
In three pins that insert in the lockhole, having only one of them is to be inserted in the circular lockhole, constitutes directly locking; Remaining two pin inserts in the lockhole of waist shape, contact with an end circular arc of the lockhole of waist shape, that is, if a pin contacts with the front end circular arc of the lockhole of the waist shape of being inserted, then another pin contacts with the rear end circular arc of the lockhole of the waist shape of being inserted, and two pins constitute symmetrical clamping locking;
The sled handle of key tool claw-plate is pulled, unclamped to external force downwards, along trapped orbit sliding rail imposed external force simultaneously, can regulate the relative position of sliding rail on trapped orbit by short distance;
Because sliding rail is direct by three pins, the locking of making a concerted effort of symmetrical clamping, therefore collided at automobile, when seat slide is subjected to intense impact, lockset and sliding rail, trapped orbit possess stronger more reliable shock resistance, anti-release ability out of control, and difficult the vibration because of being hit extracted release.
Beneficial effect
This device lockset is provided with five pins independently separately, and being moved up and down to insert in the trapped orbit lockhole by key tool control pin locks sliding rail; During the each locking of sliding rail, lockset always has three pins to participate in locking; Sliding rail has at least a pin can directly insert locking sliding rail in the trapped orbit bottom land lockhole under any non-released state in the lockset.
The side that this device has overcome the prior art locking device pawl that hangs tag fuses, and when a claw is hit tripping, then all claws all can tripping, defective that can't the secure ratcs automotive seat; Collided at automobile, seat slide is subjected to intense impact, the lockhole of trapped orbit is torn distortion because of stressed, and sliding rail vertically moves, and lockset is followed mobile, when lockset moved a pin diameter apart from the time, originally be fixed two idle pins of bottom land retaining between two adjacent lockholes of track, substitute inserts among unspoiled, the adjacent lockhole, at this moment immediately, whole five pin actings in conjunction continue the locking sliding rail, stop seat slippage out of control; Therefore this device possesses stronger more reliable shock resistance, anti-release ability out of control.
Above-mentioned, the present invention adopts lockset and key tool is set on sliding rail, five separate pins are set in lockset, do the upper and lower cotter joint action, the lockhole that some circular ports and mounting hole are alternately arranged is set at the bottom land of trapped orbit by five pins that the claw-plate of key tool is stirred lockset; During the each locking of sliding rail, lockset always has three pins to participate in locking, promptly, a pin in five pins of lockset inserts at random and does directly locking in the round keyhole of trapped orbit bottom land, make the technical scheme of symmetrical clamping locking in addition in the waist shape lockhole of two pin insertion trapped orbit bottom lands, overcome prior art and had complex structure, easy release out of control, the problems and shortcomings of no short distance regulatory function, the built-in five pin locking devices of a kind of sliding rail of automobile seat that is provided, participate in locking by three pins, utilize the circular port and the mounting hole of alternately arranging on the trapped orbit to be easy to the design feature that short distance is regulated the sliding rail latched position, make the locking device of sliding rail of automobile seat reach simple in structure, lock firm, shock resistance, anti-release out of control, the purpose that possesses the short distance regulatory function.
