Embodiment 1

[0038] Such as Figure 1 to Figure 5 As shown, a commercial vehicle seat rotation mechanism includes an upper turntable 1, a pawl 2, a middle turntable 3, cross rollers 4, a fixed seat 5, and a lower turntable 6; the bottom surface of the upper turntable 1 and the top surface of the lower turntable 6 pass through several The bolts are connected to form the inner ring of the rotating mechanism; the upper turntable 1 is provided with a middle hole, and the wall of the middle hole extends downwards to extend out of the neck of the turntable; The middle hole, the middle hole is set on the outer periphery of the lower turntable 6; the bottom of the middle turntable 3 is connected with the fixed seat 5 by several bolts to form the outer ring of the rotating mechanism; the outer ring of the rotating mechanism and the inner ring of the rotating mechanism are connected by cross rollers 4 in rotation ; The ratchet 2 is rotationally connected with the upper turntable 1, and a rotation re...

Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that: in this embodiment, the rotation reset mechanism is a return spring, the return spring is sleeved on the rotating shaft 21 of the ratchet 2, and the two ends of the return spring are respectively fixed on the ratchet. On the claw mounting plate body 131 and the rotating shaft 21.

[0056] The working principle of this embodiment is:

[0057] In the initial state, the pawl 2 is locked with the ratchet 32 ​​of the middle turntable, and the relative position of the inner ring of the rotating mechanism and the outer ring of the rotating mechanism is locked;

[0058] When the seat needs to be rotated, the ratchet 2 is operated with a cable or a cylinder, so that the ratchet 2 is rotated downwards and disengaged from the ratchet 32 ​​of the middle turntable, so as to realize the unlocking of the inner ring of the rotating mechanism and the outer ring of the rotating mechanism;

[0059] Then turn the upper turnt...

Abstract

The invention discloses a seat rotating mechanism for a commercial vehicle. The seat rotating mechanism comprises an upper rotating disc, a pawl, a middle rotating disc, a crossed roller, a fixed seat and a lower rotating disc, the upper turntable is connected with the lower turntable to form a rotating mechanism inner ring; the bottom of the middle turntable is connected with the fixed seat to form a rotating mechanism outer ring; the rotating mechanism outer ring and the rotating mechanism inner ring are rotationally connected through a crossed roller; the upper turntable is provided with a middle hole, the hole wall of the middle hole integrally extends downwards to form a turntable neck, and the middle turntable is hollowly sleeved on the turntable neck; the fixed seat is provided with a middle hole, and the middle hole is hollowly sleeved on the lower turntable; the pawl is rotationally connected with the upper turntable, and a rotary reset mechanism is arranged between the pawl and the upper turntable; a plurality of sets of ratchets are distributed on the periphery of the middle rotary disc and used for being matched with the pawls for locking. The commercial vehicle seat can meet the installation space requirement of all commercial vehicle seats, is simple in structure, small in size, light in weight, low in cost, small in rotating gap, small in rotating torque and low in noise, and meets the strength requirement of the commercial vehicle seats.

Description

technical field [0001] The invention belongs to the technical field of commercial vehicle seats, and relates to a commercial vehicle seat rotation mechanism, which solves the problem that the installation space of a commercial vehicle (heavy-duty truck) is small and the conventional rotation mechanism does not meet the requirements for installation and use. Background technique [0002] With the rapid development of the automobile industry, car seats are one of the main components of auto parts. For car seats, not only to meet the needs of driving, but also the safety, comfort and beauty of the seats have become the winning market important factor in competition. [0003] In the design of car seats, in order to adapt to different occupants and meet the comfort requirements of passengers with different postures and shapes, the angle of the seat back is generally adjustable. In order to further improve the adaptability of the seat, some seats are also increased. Rotation adju...
