AI Technical Summary
Technical Problem
In existing technology, the gap between the headrest rod and the headrest causes the headrest to shake and generate noise during vehicle operation.
Method used
By setting a snap-fit groove and a compensation block between the headrest rod and the core component base, the compensation block absorbs the tolerance, eliminates the gap, and prevents shaking. The design is simple and low-cost.
Benefits of technology
It effectively prevents the headrest from wobbling on the headrest rod, eliminates noise, and is easy and inexpensive to install.

Abstract
The headrest rod installation structure comprises a headrest assembly and a headrest rod, the headrest assembly comprises a core piece base, the upper end of the headrest rod is inserted into the core piece base and is in clearance fit with the core piece base, a clamping groove is formed in the position, close to the headrest rod, of the core piece base, a compensation block is inserted into the clamping groove, and the compensation block is arranged in the clamping groove. The side end of the clamping groove is provided with a hollowed-out part, the outer circle of the headrest rod enters the clamping groove in a protruding mode through the hollowed-out part, and the compensation block is arranged between the inner wall of the clamping groove and the outer circle of the headrest rod in an expanding mode. The tolerance between the headrest rod and the core piece base is absorbed through the compensation block, a gap between the headrest rod and the core piece base is eliminated, the core piece base is prevented from shaking relative to the headrest rod, and shaking abnormal sound is also avoided; the installation structure is simple, the compensation block is directly inserted into the clamping groove to complete assembly, arrangement is convenient, and the machining cost is low.
