[0002] With the rapid development of science and technology in my country, people have higher and higher requirements for riding comfort. At present, car seats and adjustable seats are adjusted by setting a recliner that can adjust the backrest angle. However, the operating forms of the recliners on the market are also handwheel type and handle type. The twisting handwheel is driven by the eccentric shaft to move eccentrically along its internal gear seat to adjust the backrest angle. The handle type directly drives the shift block and the inner gear plate to move through the handle, so that the inner gear plate is engaged and disengaged, and the inner gear plate is engaged with the large gear through the tension spring to position it. At the same time, the back arm is returned to its position through the power of the coil spring, so as to achieve the purpose of adjusting the angle. However, both the handwheel type and the handle type recliners have the problems of complex structure, inconvenient installation, more parts and high manufacturing cost. Summary of the invention

DETAILED DESCRIPTION

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] like Figure 1 Figure 2 Figure 3 Figure 4 As shown, the angle adjuster includes an adjusting handle 1, an adjusting core component 2 connected to the adjusting handle 1 and an adjuster housing 9, the adjusting core component 2 is provided with a through hole along its central axis, a planetary gear assembly 5 is arranged in the through hole, two adjusting disks 4 are arranged on both sides of the adjusting core component 2 and form a cavity with the through hole, the two adjusting disks 4 are fixedly connected by a fixed connecting member, the planetary gear assembly 5 is composed of an inner ring gear 8, two planetary gears 6 meshing with the inner ring gear 8 and a sun gear 7 located at the central axis position of the inner ring gear 8, the inner ring gear 8 is provided on the inner circumferential wall of the through hole, the angle adjuster achieves the adjustable purpose through the planetary gear assembly 5 and the adjusting disk 4, the structural design is reasonable, the manufacturing is simple and convenient, and compared with the traditional angle adjuster, the manufacturing cost is low and the structure is simple.

[0016] To explain in further detail, the sun gear 7 is composed of two first gears 10 and a second gear 11. The first gear 10 has a first tooth portion 12 on its outer wall that meshes with the corresponding planetary gear 6, and the second gear 11 has a second tooth portion 13 on its outer wall that meshes with the corresponding planetary gear 6. The first gear has a first flange portion 14 that extends outward and serves as a limiter, and the second gear has a second flange portion 15 that extends outward and serves as a limiter. The first tooth portion 12 and the second tooth portion 13 mesh with the respective corresponding planetary gears 6 to achieve locking. When the sun gear 7 in the planetary gear assembly 5 is rotated by adjusting the handle 1, the originally meshed sun gear 7 is rotated to the first flange portion 14 and the second flange portion 15, so that the backrest can be automatically adjusted.

[0017] To further explain, two guide grooves 16 for limiting the travel of the planetary gears 6 are provided on the adjusting disk 4, and the two planetary gears 6 have upwardly protruding limit portions 18 along the center axis, and the limit portions 18 are located in the guide grooves 16.
