Description
Technical field
The invention belongs to automotive seating art fields, and in particular to a kind of lock ring structure of back seat backrest.
Background technique
The fixation of automobile rear-row seat-backrest mostly uses install lock ring on the C column of present chair back two sides greatly, for bearing
The strength of entire backrest.Existing lock ring is fixed structure, is usually made of lock ring and lock seat, and lock ring is " U "-shaped, lock
The two ends of ring are fixed on lock seat, and are fixed on C column by latching seat.
The shortcoming of existing lock ring structure is: lock ring position fixation after installation can not be adjusted, and cause back seat
Inclination angle can not also adjust, be unable to satisfy the individual demand of passenger itself, especially for long-distance travel vehicle come
It says, riding comfort is in urgent need to be improved.
Summary of the invention
The present invention is intended to provide a kind of adjustable electronic lock ring, can be carried out a certain range of electrodeless adjustment, thus real
The inclination angle of existing back seat backrest can arbitrarily be adjusted in a certain range, improved riding comfort, met the individual character of passenger
Change demand.
For this purpose, the technical scheme adopted by the invention is as follows: electronic lock ring, including lock is adjusted in a kind of back seat backrest
Ring and lock mounting base, further include motor, screw rod and sliding block, and the slide block set constitutes leading screw and nut mechanism on screw rod, institute
Lock ring to be stated to be fixedly mounted on sliding block, screw rod is mounted in lock mounting base, and the motor drives sliding block to slide by screw rod,
To drive lock ring to move left and right.
The lock mounting base uses sheet metal component, including bottom plate and both side plate, the screw rod as a preferred embodiment of the above solution,
Left and right ends be separately mounted to lock mounting base correspondence side plate on, at the position that each side plate is connect with bottom plate rush have reinforcement
Muscle.The structure of optimization lock mounting base, realizes light-weight design, and ensure to latch the integral strength of mounting base.
Further preferably, two guide rods are also equipped on the sliding block, two guide rods are arranged symmetrically in screw rod
Upper and lower two sides, the left and right ends of guide rod are separately mounted on the correspondence side plate of lock mounting base.Symmetrically arranged double guide rods,
Ensure stress balance in sliding block moving process and entirety will not deflect.
Further preferably, the sliding block is provided with blind hole at the middle position of the bottom plate side of lock mounting base,
Cylindrically coiled spring is installed in the blind hole, "T"-shaped rubber mat is housed between sliding block and bottom plate, the end of "T"-shaped rubber mat is supported
On bottom plate, the bar portion of "T"-shaped rubber mat is protruded into blind hole, and one end of cylindrically coiled spring is against blind via bottom, and " T " is inserted in one end
It is against after the bar portion of shape rubber mat on the step surface of "T"-shaped rubber mat, the end of the "T"-shaped rubber mat is tapered to reduce and bottom plate
Contact area；When sliding block sliding, cylindrically coiled spring and "T"-shaped rubber mat are moved left and right with sliding block.To ensure that sliding block is suitable
Smooth sliding, sliding block are vacantly arranged, and there are gaps between bottom plate；But when driving in order to avoid long-distance bumpy road, screw rod and cunning
Block generates shake, so that back seat be driven to generate shake and abnormal sound, adds blind hole, cylindrically coiled spring and "T"-shaped rubber mat, energy
It is shaken caused by buffering bumpy road, avoids abnormal sound, improve comfort；But since sliding block is adjustable, can stop in any position
Under, then the Buffer Unit that cylindrically coiled spring and "T"-shaped rubber mat are constituted is moved together with sliding block, "T"-shaped rubber mat uses taper
End can reduce the mobile generation resistance of Buffer Unit added to sliding block, structure is skilful to reduce the contact area with bottom plate
It is wonderful, and function is reliable.
Further preferably, the screw rod passes through and is set with bushing at the position of both side plate, and the one of guide rod belt end
End cap is equipped with butterfly gasket, and the other end is set with retaining retainer ring.
Further preferably, the fastening bolt being triangularly arranged in the lock mounting base equipped with three, being used for can
Adjust installation of the electronic lock ring on automotive C column.
Further preferably, the lock ring is bent into " u "-shaped by steel wire, and is fixed on cunning by the open end of " u "-shaped
On block, wherein a side of " u "-shaped is moved closer to since middle part towards another side, so that the open end width of " u "-shaped
Less than closed end width.Bending part is conducive to increase the intensity of lock ring, while ensuring that closed end width meets requirement
Under the premise of, reduce the width of open end, to reduce the width of sliding block, to vacate the stroke that more spaces increase sliding block.
Beneficial effects of the present invention: driving lock ring mobile by leading screw and nut mechanism, realizes lock ring in screw rod stroke
The adjusting of any position in range, so that back seat backrest is enable to carry out the electrodeless adjustment of arbitrary angle in a certain range,
Passenger can be adjusted in due course as needed, and motor driven, high degree of automation, and then improve riding comfort.
