Description

Technical Field

[0001] The invention belongs to the field of automobile parts, and in particular relates to an adjustable mechanical wing structure. Background Art

[0002] In the internal structure of car seats, the side wing supports of the seat back frame and the seat cushion frame are usually realized by welding steel wire and sheet metal parts, which have poor support effect and no adjustment function. In order to achieve the adjustment of the side wing, many models on the market currently use pneumatic side wing structures, but the pneumatic side wing structure has problems such as insufficient travel and soft support, which can no longer meet the comfort requirements of drivers and passengers.

[0003] Chinese patent CN 108045271 B discloses "an adjustable wing structure". This wing structure increases the travel range of the pneumatic wing structure by introducing a worm screw mechanism, thereby improving the comfort experience. However, this wing structure still has the following problems: (1) The structure occupies a large space. Due to the space constraints of the seat frame, it cannot be applied to many car seats; (2) The wing structure has low strength and poor support effect; (3) The wing structure is too complicated, with many transmission mechanisms, which makes it difficult to install. In addition, it is easy to make abnormal noises, stop turning, get stuck, etc. during use, which increases the frequency of subsequent maintenance; (4) The travel is not large enough (about 30mm), which cannot meet the requirements of cutting-edge customers and affects the comfort of drivers or passengers; (5) There are many manufacturing processes and the manufacturing cost is high. Summary of the invention
