Specific embodiment
As shown in Figures 1 to 7, the utility model automotive seat step-less adjustment armrest mechanism, armrest mechanism include handrail
Installing plate 1, spacer pin 5, unilateral bearing, unlock support shaft 10, mounting bracket 24, internal fixation plate 23 and tripper.
Hinged axle sleeve 2 is installed in mounting bracket 24；Handrail installing plate 1 is sleeved on hinged axle sleeve 2, handrail installation
Plate 1 can be rotated around hinged axle sleeve 2；Hinged axle sleeve 2 is equipped with unilateral bearing inner ring 3, and be provided with pad by 6 fixing sleeve of connecting key
Circle and connection bolt 19；Bearing dowel 26 is installed on internal fixation plate 23；
The one end for unlocking support shaft 10 is mounted on handrail installing plate 1, and the other end is mounted on internal fixation plate 23；Unlock
Unlock bracket torsion spring 12 and rotor solution lock support 11 are set on support shaft 10；The one end for unlocking bracket torsion spring 12 is mounted on handrail
On installing plate 1, the other end is mounted on rotor solution lock support 11；One end of rotor solution lock support 11 is cooperation control rotor 9
Jag；The hole of installation connection steel wire 13 is provided on the other end of rotor solution lock support 11；
Unilateral bearing includes unilateral bearing inner ring 3 and unilateral bearing outer ring 7；Unilateral bearing inner ring 3 and unilateral bearing outer ring 7
Upper and common rotor 8 controls the face that rotor 9 contacts as inner concave arc surface, sliding slot of the inner concave arc surface as rotor motion；Unilateral bearing
The outer surface of outer ring 7 is equipped with the fixation cotter way 30 of installation bearing dowel 26, and the inner surface of unilateral bearing outer ring 7, which is equipped with, to be held
Receive common rotor 8 common rotor slot 29 and accommodate control rotor 9 wedge groove 27；Common rotor 8 and control rotor 9 are in list
It is moved between bearing inner race 3 and unilateral bearing outer ring 7；Common rotor 8, control rotor 9 are cydariform, control the both ends of rotor 9
Equipped with 11 matched jag of rotor solution lock support control rotor connecting rod 28；Common rotor 8, control rotor 9, unilateral bearing
Lubricating grease is coated on inner ring 3, unilateral bearing outer ring 7, coordinates sliding slot and lubricating grease so that the rotation of rotor and unilateral bearing is matched
It closes firm, durable.
Wedge groove 27 divides for compared with big end 271 and small end 272, and compared with big end 271 and small end 272, difference lies in containing body
Long-pending size, if receiving volume is more than the volume of control rotor 9, for compared with big end 272；If receiving volume is less than control rotor 9
Volume, then be small end 272；Have compared with big end 271 makes the space of 9 free movement of control rotor enough, and the space of small end is small
In the volume of control rotor 9；Rotor solution lock support 11 can resist control rotor connecting rod 28 so that control rotor 9 is maintained at wedge
In the relatively big end 271 of shape slot 27；
Spacer pin 5 is fixed on handrail installing plate 1, and spacer pin 5 is movable in the arc groove 31 of banking stop 4, the banking stop 4
It is welded on hinged axle sleeve 2；The limit position of handrail is limited by controlling movement of the spacer pin 5 in 4 arc groove 31 of banking stop
It puts.
Tripper includes attacker's mounting bracket 14 mounted on 1 front end of handrail installing plate, consolidates in attacker's mounting bracket 14
Surely there is unlock attacker 15, the both ends of attacker's locating shaft 16 pass through unlock attacker 15 to be mounted in attacker's mounting bracket 14, Kou Shouding
Attacker's reduction torsion spring 17 is set on the axis 16 of position, the both ends of attacker's reduction torsion spring 17 are fixed in attacker's mounting bracket 14；Unlock
One end of attacker 15 is connected with connecting steel wire 13.15 surface of attacker is unlocked covered with attacker's decorative cover 18.
The operation principle of the utility model is as follows：The unilateral bearing direction of the utility model is counter clockwise direction, i.e. handrail
The direction being rotated up.The up and down adjustment angle of this handrail design be 130 °, be by banking stop 4 and be fixed on handrail pacify
1 spacer pin 5 realizes that, when handrail rotates upwardly and downwardly, banking stop 4 is will not to turn with handrail installing plate 1 jointly in loading board
It is dynamic, and spacer pin 4 is then as handrail installing plate 1 rotates upwardly and downwardly in the arc groove 31 of banking stop 4, it is lower thereon to adjust the angle then
Opening angle depending on its arc groove 31.Adjust its 31 opening angle of arc groove i.e. high-low limit position of adjustable arm.
Bearing dowel 26 in fixed plate 23 is used to unilateral bearing outer ring 7 being fixed on handrail installing plate 1 so that outside unilateral bearing
Circle 7 is rotated with handrail.
When the utility model is located at minimum angle as shown in Figure 1, since spacer pin 5 has been in 4 arc groove 31 of banking stop
Extreme higher position, at this time handrail can not continue to rotate down.
When the utility model is rotated up, as shown in fig. 6, at this time there is no operation unlock attacker 15, therefore rotor unlocks
Stent 11 is not contacted with control rotor 9；Control rotor 9 in unilateral bearing moves in the relatively big end 271 of wedge groove 27, by
It is freely rotated in thering are enough spaces to give control rotor 9 compared with big end 271, therefore handrail is rotated up having no any obstacle, it can be certainly
By moving free position to.
If in the case where not operating unlock attacker 15, i.e., under non-unlocked state, if handrail is wanted to rotate down, control at this time
Rotor 9 can roll to the small end 272 of wedge groove 27, but because the space of small end 272 is less than the volume of control rotor 9, nothing
Method allows control rotor 9 to be freely rotated, therefore handrail can be because entire unilateral bearing part be blocked, and can not rotate down, that is, realizes
It is rotated up freely accessible, rotates down confined effect.
If operating unlock attacker 15, i.e., in the unlocked state, at this time since pull-up understands lock hand 15, connect so as to pass through
It connects steel wire 13 and holds rotor solution lock support 11, rotor solution lock support 11 is rotated around rotor field spider axis 10, rotor solution lock support 11
One end resist control rotor 9 on control rotor connecting rod 28.
In the unlocked state, handrail moves upwards and non-unlocked state and indistinction.
In the unlocked state, control rotor 9 by one end of rotor solution lock support 11 due to being resisted, as shown in Fig. 7, this
When control rotor 9 be limited in the relatively big end 271 of wedge groove 27, even if handrail rotates down, control rotor 9 will not enter to
In the small end 272 of wedge groove 27；Unilateral bearing does not have " unidirectional " function at this time, i.e. unilateral bearing can be realized normally at this time
, can Double-directional rotary plain bearing function.
Common rotor 8, due to being placed in common rotor slot 29, the shape of common rotor slot 29 as shown in Fig. 1,5,6,
For an arc, clockwise, counterclockwise rotation will not all block.
When unclamp unlock attacker 15 when, rotor solution lock support 11 can because unlock bracket torsion spring 12 discharge press solution lock
The power that is received during hand 15 and rotor solution lock support 11 is rebounded non-unlocked state when position, similarly, unlock attacker 15 also can
Should be attacker's reduction torsion spring 17 release power and rebound non-unlocked state when position.
In summary, the handling characteristics of the utility model are：Non- unlocked state can only turn, upwards after going to suitable position
Stop；Unlocked state rotates upwardly and downwardly, and unclamps unlock attacker 15 after going to suitable position, that is, stops.
Above-described embodiment of the utility model is not the restriction to scope of protection of the utility model, the reality of the utility model
It is without being limited thereto to apply mode, all this kind the above according to the present utility model, according to the ordinary technical knowledge of this field and used
With means, under the premise of the above-mentioned basic fundamental thought of the utility model is not departed from, the utility model above structure is made its
The modification, replacement or change of its diversified forms, should all fall and be within the protection scope of the utility model.
