Problems solved by technology

[0003] The above three types of recliners have their own advantages and disadvantages in terms of performance. Among them, the ratchet pawl mechanism has disadvantages such as limited adjustment range, limited strength, large clearance, and limited adjustment accuracy; the planetary gear transmission adjustment mechanism has limited strength, large clearance, and large volume. Disadvantages: The transmission of the eccentric adjustment mechanism based on the principle of planetary gear transmission with less tooth difference has the disadvantages of non-concentric transmission, uneven operation and inability to be used for monotony.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0035] The horizontal, vertical and Figure 5 , Image 6 The orientation shown is a reference, showing a relative positional relationship perpendicular to each other.

[0036] Such as Figures 1 to 4 As shown, an angle adjustment mechanism, its structure includes a fixed plate 1, a sliding block 2, a toothed plate 3 and a moving plate 4 arranged in sequence along the axial direction, and a hoop 11 is sleeved on the outer side of the fixed plate 1 and the moving plate 4. , wherein the moving disk 4 is fixedly connected with the hoop 11, and the fixed disk 1 and the hoop 11 rotate in cooperation. When the angle adjustment mechanism works, the moving disk 4 rotates coaxially relative to the fixed disk 1. An inner ring gear 4a is provided on the moving disc 4, and an outer tooth 3a internally meshing with the inner ring gear 4a is provided on the circumferenti...

Abstract

The invention discloses an angle adjusting mechanism which comprises a fixed disc, a sliding block, a fluted disc and a movable disc which are sequentially arranged in the axial direction, and the movable disc can concentrically rotate relative to the fixed disc; an inner gear ring is arranged on the movable disc, outer teeth meshed with the inner gear ring are arranged on the fluted disc, and thenumber of the outer teeth is smaller than that of the inner gear ring. The sliding block is in sliding fit with the fixed disc, the fluted disc is in sliding fit with the sliding block, and the sliding direction of the sliding block relative to the fixed disc is perpendicular to the sliding direction of the fluted disc relative to the sliding block. The movable disc is provided with an installation hole, a driving shaft is installed in the installation hole in an eccentric rotating mode, and the driving shaft stretches into a center hole of the fluted disc and is used for driving the fluted disc to move. The angle adjusting mechanism has the advantages that the concentric rotation of the movable disc can be achieved, the situation that transmission is not concentric and operation is not smooth is avoided, and the use comfort of the angle adjusting mechanism is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of seat adjustment, and in particular relates to an angle adjustment mechanism. Background technique [0002] At first, the recliner was mainly used on the car seat to adjust the inclination angle of the seat back. At present, the recliner can be roughly divided into the following three categories: one is the locking adjustment mechanism that adopts the principle of the ratchet and pawl mechanism, The second type is a gear-type adjustment mechanism that adopts the principle of planetary gear transmission, and the third type is an eccentric adjustment mechanism that adopts the principle of planetary gear transmission with small tooth difference. [0003] The above three types of recliners have their own advantages and disadvantages in terms of performance. Among them, the ratchet pawl mechanism has disadvantages such as limited adjustment range, limited strength, large clearance, and limited adjustment accura...
