Detailed Description
The invention is further described below with reference to examples and figures.
Referring to fig. 1 to 4, a seat back unlocking mechanism of a convenient seating system of an automobile comprises a rotating plate 2, a base plate 14, and an operating assembly and a locking assembly which are all arranged on the base plate 14, wherein the rotating plate 2 and the base plate 14 are rotationally connected through a recliner 1, when the recliner 1 is locked, the rotating plate 2 and the base plate 14 cannot rotate relatively, the relative position is locked, and when the recliner 1 is unlocked, the rotating plate 2 and the base plate 14 can rotate relatively.
Referring to fig. 1 to 4, the locking assembly includes an angle adjuster unlocking end 11 and a limiting pulling piece 12. The angle adjuster unlocking end 11 is connected with the angle adjuster 1 through welding, and the angle adjuster 1 can be locked and unlocked by rotating the angle adjuster unlocking end 11, and the angle adjuster unlocking end 11 has a trend of elastic reset (a reset spring is arranged in the angle adjuster 1), namely the angle adjuster unlocking end 11 has a trend of elastic rotation to a locking position. The limiting poking piece 12 is rotatably mounted on the base plate 14 through the torsion spring, when the limiting poking piece 12 is located at the locking position, the limiting poking piece 12 can interfere with the rotation of the rotating plate 2, so that the seat back can rotate by a certain angle and cannot be leveled, when the limiting poking piece 12 rotates to the unlocking position, the limiting poking piece 12 is used for yielding the rotating plate 2, and the rotating plate 2 can rotate by a larger angle relative to the base plate 14, so that the seat back can be leveled.
It should be noted that, the unlock positions of the recliner unlock end 11, the recliner unlock link 13, and the limit dial 12 refer to the respective current positions when the rotating plate 2 is able to rotate freely relative to the base plate 14 (the seat back can be put flat), and the lock positions refer to the respective current positions when the rotating plate 2 is unable to rotate freely relative to the base plate 14.
Referring to fig. 6, the shaft portion 111 of the recliner unlocking tip 11 includes two arcuate segments 111a and two inner cut segments 111b, and the two arcuate segments 111a and the two inner cut segments 111b are disposed in a pair by pair. And, the maximum aperture of the inscribed section 111b is smaller than that of the arc-shaped section 111 a. Further, the inner section 111b is a planar structure to facilitate the design of the steering assembly.
