Embodiment
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：
The utility model discloses a kind of built-in child safety seat armrest of seat of height step-less adjustment, rear row seat is arranged on
Chair centre position both sides, the mechanism can switch between off working state and working condition, in off working state, handrail height
It is concordant with seat cushions, used for adult normal；In working condition, according to seat cushion rising height and child passenger height to helping
Hand is highly adjusted, and is adjusted to the height for being adapted to the child passenger, increase ride quality, while limiting child occupant from seat
Pad slides, and improves security.
As shown in figure 1, the armrest adjustment mechanism is arranged on automobile rear seat centre position both sides, the complete phase of structure on two sides
Together, it is concordant with seat cushion in off working state.
As shown in Fig. 2 in working condition, handrail is raised and is adjusted to suitable height by the governor motion.
A kind of as shown in figure 3, built-in child safety seat armrest of seat concrete structure of height step-less adjustment of the utility model
It is as follows：Include handrail body, slide rail, slide bar, first connecting rod, second connecting rod, first to fourth bearing pin, lower connecting plate, driving electricity
Machine, screw rod, screw rod pedestal, sliding block and chute.
Handrail body is hollow and lower ending opening；Slide rail is arranged in handrail body, parallel to automotive floor panel.
The upper end of first connecting rod is hinged, centrally through the second bearing pin by the first bearing pin in one end of slide rail and handrail body
With the center of second connecting rod is be hinged, lower end is hinged by the 3rd bearing pin and sliding block；The upper end of second connecting rod is provided with and passed through for slide bar
Through hole, lower end is hinged by one end of the 4th bearing pin and lower connecting plate；Slide bar is arranged on slide rail through through hole, can be along cunning
Rail is slidably.
Lower connecting plate is fixed on automotive floor panel；Chute is arranged on lower connecting plate, and chute is parallel with slide rail；Sliding block is set
Put on chute, can be along chute slidably.
Screw rod pedestal is fixed on lower connecting plate, which is provided with the smooth bore passed through for screw rod；Sliding block is provided with and spiral shell
The screwed hole that bar matches；Screw rod is threadedly coupled through the smooth bore on screw rod pedestal and sliding block, and screw rod and lower connecting plate
It is parallel.
Motor is arranged on lower connecting plate, and its output shaft and screw rod are fixedly linked, for drive screw turns.
Screw rod uses thread form angle as 60 ° of triangle fine thread, now, because screw flight lift angle rubs less than equivalent
Angle is wiped, meets condition of self-locking, self-locking can be realized at an arbitrary position by itself screw thread.
During work, motor drive screw turns, the screw thread cooperation of screw rod and sliding block causes sliding block to be slided in chute,
Sliding block is hinged with first connecting rod, and the motion of screw rod has driven the motion of first connecting rod, and the second bearing pin passes through first connecting rod
With second connecting rod, first connecting rod upper end is hinged in handrail body, and second connecting rod lower end is hinged on the pedestal on the upside of lower connecting plate
On, therefore connecting rod only can be achieved to rotate, and can not realize translation；Sliding block slides the lifting for realizing mechanism in chute, due to lower company
Fishplate bar is fixed on automotive floor panel, therefore can realize the lifting of handrail panel, that is, realizes the step-less adjustment of handrail height, and is passed through
Screw flight realizes self-locking.
