[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model discloses an intelligent car seat with an adjustable headrest.

[0017] Reference Figure 1-3An intelligent car seat with an adjustable headrest includes a seat body 1 and a headrest 3. The headrest 3 is positioned above the seat body 1. A through hole is provided at the top of the seat body 1, and a slide rod 2 is slidably disposed inside the through hole. The upper end of the slide rod 2 is fixedly connected to the headrest 3. A limit block 4 is fixedly disposed on one side of the seat body 1. A through groove is provided on the surface of the limit block 4, and a push rod 5 is slidably disposed inside the through groove. Both the through groove and the push rod 5 have rectangular cross-sections. The rod wall of the push rod 5 abuts against the inner wall of the through groove, allowing the push rod 5 to slide stably. A connecting rod 6 is fixedly disposed at the upper end of the push rod 5 and on the side close to the headrest 3. One end of the connecting rod 6 is fixedly connected to the headrest 3. A rotating rod 8 is disposed below the push rod 5. One end of the rotating rod 8 is rotatably connected to the seat body 1. A rotating strip 9 is fixedly sleeved on the rod wall of the rotating rod 8. A transmission mechanism for driving the push rod 5 to move longitudinally is provided at the upper end of the rotating strip 9, and a limiting mechanism for restricting the rotation of the rotating rod 8 is provided at the lower end of the rotating strip 9.

[0018] Reference Figure 1-3 The transmission mechanism includes a movable frame 7 and a round pin 10. The movable frame 7 is fixedly installed at the lower end of the push rod 5. The round pin 10 passes through the interior of the movable frame 7. One end of the round pin 10 is fixedly connected to the upper end of the rotating bar 9. An anti-detachment ring 11 is fixedly sleeved on the end of the round pin 10 away from the rotating bar 9 to effectively prevent the round pin 10 from slipping out of the movable frame 7.

[0019] Reference Figure 1-3 The limiting mechanism includes a threaded rod 13. The lower end of the rotating bar 9 has a threaded hole. The threaded rod 13 is threaded into the inside of the threaded hole. The side wall of the seat body 1 has multiple insertion holes 12 arranged in a ring array around the rotating rod 8. One end of the threaded rod 13 is inserted into the insertion hole 12. The end of the threaded rod 13 away from the insertion hole 12 is fixedly sleeved with a knob 14 to facilitate the rotation of the threaded rod 13.

[0020] In this utility model, when the user needs to adjust the height of the headrest 3, they hold the knob 14 and rotate the threaded rod 13 counterclockwise to pull the threaded rod 13 out of the current insertion hole 12, thus releasing the restriction on the rotating bar 9. Using the rotating rod 8 as the axis, the rotating bar 9 is rotated upwards or downwards: when the rotating bar 9 is rotated upwards, the pin 10 at its upper end rotates synchronously with the rotating bar 9. The pin 10 slides within the movable frame 7 and pushes the movable frame 7 upwards. The movable frame 7 drives the push rod 5 to slide upwards along the through groove of the limiting block 4. The push rod 5, through the connecting rod 6, drives the headrest 3 to rise synchronously. The rod 2 slides upward along the through hole of the seat body 1, serving as a guide; when the rotating bar 9 is rotated downward, the round pin 10 pulls the movable frame 7 downward, which in turn drives the headrest 3 to descend through the push rod 5 and connecting rod 6, realizing continuous adjustment of the headrest height. Users can adjust it in real time according to their own height and sitting posture without repeatedly plugging and unplugging or switching gears until a comfortable position is found; after adjustment, the knob 14 is rotated clockwise to insert the threaded rod 13 into the corresponding insertion hole 12, relocking the rotating bar 9 and preventing the headrest 3 from moving on its own; the whole adjustment process is convenient to operate.

[0021] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
