Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat headrests, and more specifically, to an automobile seat headrest. Background Art

[0002] In the current technical field of automotive accessories, car seat headrests are an important part of improving riding comfort, and the convenience of their installation and removal has a direct impact on user experience. However, existing car seat headrests have certain shortcomings in this regard. First of all, the installation process of many seat headrests is complicated, requiring the use of specific tools or following cumbersome steps, which not only increases the difficulty of operation for users, but also prolongs the installation time. In this case, even for experienced users, installing the headrest has become a time-consuming and laborious task, which undoubtedly reduces the convenience of use.

[0003] On the other hand, when the headrest needs to be disassembled for cleaning or replacement, the existing design is often not user-friendly. Since the disassembly process may involve multiple fixing points or complex structures, users may encounter difficulties when trying to disassemble, and may even damage the headrest or seat. This inconvenience not only affects the user's daily maintenance work, but may also increase maintenance costs and reduce the overall user experience of the car seat headrest. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a car seat headrest, which has the following beneficial effects:

[0017] 1. The design of the fixing mechanism enables the car seat headrest to be firmly installed on the seat. The headrest body is connected to the insertion rod through the connecting mechanism, and the insertion rod is fixed to the seat through the fixing sleeve. This structure not only ensures the stability of the headrest, but also facilitates the installation process. The fixed installation of the fixing sleeve and the sliding connection of the insertion rod allow the headrest to be adjusted according to the size of different seats, thereby improving the adaptability of the equipment.

[0018] 2. The clamping mechanism realizes a tight connection between the headrest and the seat through the cooperation of the telescopic rod and the push spring. When the insertion rod is inserted into the fixing sleeve, the compression of the push spring causes the top head to expand and contract outward, so that the insertion rod can smoothly enter the fixing sleeve. When the insertion rod is in place, the elastic force of the push spring causes the top head to contact the annular groove, thereby realizing a firm fixation of the headrest and the seat. This clamping method not only simplifies the operation process, but also improves the installation efficiency.

[0019] 3. The connecting mechanism realizes a firm connection between the headrest body and the insertion rod through the cooperation of the fixing rod and the threaded section. The installation of the fixing rod and the threaded connection of the threaded section enable the headrest body to be firmly connected to the insertion rod. This structure not only ensures the stability of the headrest, but also facilitates the installation process. BRIEF DESCRIPTION OF THE DRAWINGS
