The invention discloses a small angle adjuster for an automobile seat backrest. The small angle adjuster comprises a gear, a gear ring and a hoop, a gear body part meshed with the gear ring is arranged on the first side of the gear, a welding panel is arranged on the second side of the gear, the gear body part is integrally connected with the welding panel, under the condition that the diameter ofthe welding panel is not changed, the diameter of the gear body part and the diameter of the gear ring are reduced, a transition groove is naturally formed between the welding panel and the gear bodypart, the hoop is sleeved with the transition groove, and the outer ring of the hoop sleeves the gear ring. The gear is divided into a gear body part and a welding panel part in the axial direction according to functions, a metal injection molding process is adopted for integral molding, the diameter of the tooth body part is independently reduced, a groove-shaped structure is formed between thetooth body part and the welding panel in a natural transition mode to install the hoop, the defect that the diameter of the welding face in a traditional angle adjuster is limited by the inner diameter of the hoop is overcome, under the condition that the outer diameter of the angle adjuster is integrally reduced, the welding face is basically unchanged, and the welding strength of the angle adjuster is met.
本发明公开了一种汽车座椅靠背小型调角器,包括齿轮、齿圈和抱箍,齿轮的第一侧设置有与齿圈啮合的齿体部分,齿轮的第二侧设置有焊接面板,齿体部分与焊接面板一体连接,在不改变焊接面板的直径的情况下,缩小齿体部分和齿圈的直径,于焊接面板与齿体部分之间自然形成过渡凹槽,抱箍套设于过渡凹槽内且抱箍的外圈套住齿圈。本发明将齿轮按功能在轴向上划分为齿体部分和焊接面板两部分,采用金属注射成型工艺一体成型,单独减小齿体部分的直径,于齿体部分和焊接面板之间自然过渡形成一槽状结构来安装抱箍,克服传统调角器中焊接面直径受抱箍内径限制的弊端,在调角器外径整体减小的情况下,满足焊接面基本不变,满足调角器的焊接强度。
