Four-direction electric adjusting headrest structure and using method thereof

Abstract

The invention relates to a four-direction electric adjusting headrest structure and a using method thereof. The four-direction electric adjusting headrest structure comprises a front shell and a rear cover which are arranged front and back, a guide mechanism moving front and back is arranged between the front shell and the rear cover, a containing space is formed between the front shell and the rear cover, an insertion pipe penetrates into the containing space from bottom to top, and a lifting base is slidably installed on the insertion pipe located in the containing space; the lifting base is fixedly connected with the rear cover; a transmission mechanism is mounted in the lifting base; the front shell is fixedly provided with a transverse rack backwards penetrating through the lifting base, and further comprises a longitudinal rack fixedly connected with the insertion pipe; the transmission mechanism comprises a first gear and a second gear which are coaxially arranged, the first gear is meshed with the longitudinal rack, and the second gear is meshed with the transverse rack; the first gear rotates to move up and down relative to the longitudinal rack meshed with the first gear, and the transmission mechanism and the lifting base drive the rear cover and the front shell to move up and down; and the second gear rotates to enable the transverse rack meshed with the second gear to move back and forth to pull the front shell to move back and forth. Therefore, up-down and front-back four-direction adjustment of the headrest is achieved, layout is optimized, and use is convenient and reliable.

Description

technical field [0001] The invention relates to the technical field of seat headrests, in particular to a structure of a four-way electric adjustable headrest and a method for using the same. Background technique [0002] Car seats are generally equipped with adjustable headrests, such as up and down two-way height adjustment, front and rear two-way position adjustment or four-way adjustment, to meet the needs of different users and enhance the comfort and safety of the user's neck sex. [0003] In the prior art, the four-way adjustable headrest usually uses two sets of different adjustment mechanisms to realize the adjustment in the up and down or front and rear directions respectively. The existence of the two sets of mechanisms often makes the internal structure of the headrest complex and the parts are complicated, resulting in the headrest as a whole. Larger volume. Contents of the invention [0004] Aiming at the shortcomings in the above-mentioned existing product...
