[0029] Please refer to Figures 1-10 ,

[0030] Embodiment one: a kind of headrest for being applied to the up and down adjustable headrest of car seat, including headrest body, pillow rod 300, locking plate body 400, two guide sleeve assemblies are formed, headrest body includes front shell 100, rear shell 200, pillow rod 300, locking plate body 400, pillow rod 300 is symmetrically arranged at the bottom end of rear shell 200 two sides.

[0031] Guide sleeve assembly includes guide sleeve body 500 and spring sheet 600, and two first locking plate sides 400-1, second locking plate sides 400-2 are symmetrically arranged in the two sides of locking plate body 400, and the side of first locking plate side 400-1 is provided with first square hole 400-3, and the side of second locking plate side 400-2 is provided with second square hole 400-4.

[0032] First clamping groove 500-1, second clamping groove 500-2, third clamping groove 500-3 are evenly provided on guide sleeve body 500, and the end of guide sleeve body 500 is provided with guide sleeve hole position 500-4, and the top of guide sleeve body 500 is provided with deep groove 500-5, and the top of guide sleeve body 500 is also provided with buckle structure 500-6.

[0033] First square hole 400-3 and second square hole 400-4 are symmetrically arranged in the two sides of locking plate body 400.

[0034] Embodiment two: the difference between this embodiment and embodiment one is that, first clamping groove 500-1, second clamping groove 500-2, third clamping groove 500-3 are evenly arranged in the bottom end of the side of guide sleeve body 500.

[0035] Embodiment three: the difference between this embodiment and embodiment one is that the pillow rod 300 is in the shape of U.

[0036] The pillow rod 300 provides better support.

[0037] Embodiment four: the difference between this embodiment and embodiment one is that the spring sheet 600 is in the shape of wave.

[0038] The spring sheet 600 provides better buffering.

[0039] In this embodiment, due to the existing headrest, the standard size of the headrest may not provide accurate support for different body types and neck curves, and the height of the headrest may not be enough for people with higher body, so that their necks cannot be properly supported, and for people with shorter body, the headrest may be too high, causing uncomfortable posture such as head forward.

[0040] In summary, in the specific implementation, the headrest body includes a front shell 100 and a rear shell 200, which cooperate with each other to form the external contour and internal accommodating space of the headrest,

[0041] The guide sleeve assembly is composed of a guide sleeve body 500 and three spring sheets 600 installed in the guide sleeve slots, and is arranged to be installed in the first square hole 400-3 and the second square hole 400-4 at both ends of the locking plate body 400, and works with the locking plate body 400, so that the headrest can be stably maintained at the set position and will not easily change the height or appear loose and shake due to vibration, providing stable support for the neck of the passenger.

[0042] The locking plate body 400 is arranged to be horizontally placed at the bottom end inside the rear shell 200 and works with the guide sleeve assembly, and the pillow rod 300 is arranged to be inserted in the headrest body in the vertical direction and is clamped with the guide sleeve assembly.

[0043] The spring sheet 600 is designed to have an arc-shaped sheet structure, which is respectively embedded in the first clamping slot 500-1, the second clamping slot 500-2 and the third clamping slot 500-3, and can provide certain elastic force and friction force, so that the pillow rod 300 is stably clamped in the guide sleeve body 500 under normal circumstances, thereby maintaining the headrest at the set height position.

[0044] Due to the elastic deformation characteristics of the spring sheet 600, the spring sheet 600 will gradually deform elastically under external force, reducing the pressure and friction force on the pillow rod 300, so that the pillow rod 300 can slide relatively in the guide sleeve body 500. At this time, the pillow rod 300 can be smoothly moved upward or downward to realize the height adjustment of the headrest.

[0045] In the adjustment process, the elastic force of the spring sheet will change accordingly with the movement of the pillow rod, when the pillow rod 300 is adjusted to the appropriate height, the external force disappears, the spring sheet 600 relies on its own elastic restoring force to fix the pillow rod 300 again, and ensures that the headrest is stable and reliable at the new height position, and will not be displaced due to subsequent vehicle vibration or other interference factors.

[0046] The locking plate body 400 is horizontally placed at the bottom end inside the rear shell 200, and plays a crucial role in limiting and supporting the pillow rod 300. Its position and shape design are matched with the structure of the pillow rod 300 and the guide sleeve assembly. When the pillow rod 300 is inserted into the guide sleeve hole 500-4 and cooperates with the guide sleeve assembly, the locking plate body 400 can effectively prevent the pillow rod 300 from excessive downward displacement. During vehicle driving, especially when encountering bumpy road or emergency braking, acceleration, etc., the headrest will be subjected to a larger external force.

[0047] The locking plate body 400 bears and disperses these external forces through close contact with the pillow rod 300, avoiding the headrest from sliding off the pillow rod 300 or excessive shaking due to accidental stress, etc. The first locking plate side 400-1 and the second locking plate side 400-2 are designed as smooth and continuous curved surfaces. When the guide sleeve body 500 interacts with the locking plate body 400, the curved surface can effectively eliminate the gap. At the same time, the design of the curved surface can also make the force transmission more uniform and smooth. When the headrest is subjected to external force, it can better disperse the force to the entire locking plate structure, further enhancing the impact resistance of the headrest.

[0048] The guide sleeve body 500 is designed with a buckle structure 500-6 on three sides of the outside. When inserted into the headrest body, it can be firmly fixed to ensure that the guide sleeve body 500 normally plays a guiding and clamping function on the pillow rod 300 inside the headrest, ensuring that the position of the guide sleeve body 500 inside the headrest is accurate and cannot be displaced. At the same time, the buckle structure 500-6 makes its installation inside the headrest body quick and easy. The other side of the guide sleeve is designed with a first clamping groove 500-1, a second clamping groove 500-2, and a third clamping groove 500-3. The clamping groove is used to place the spring sheet 600, which can stably accommodate the spring sheet and prevent it from shifting or falling off during use.

[0049] At the same time, the guide sleeve is designed with a deep groove 500-5 on the upper part, which can be precisely embedded in the first square hole 400-3 and the second square hole 400-4 at both ends of the locking plate, playing a key role in positioning and fixing. This connection method not only can accurately position the guide sleeve in the horizontal direction, ensuring that the installation angle and position of the guide sleeve inside the headrest always remain consistent, but also can effectively share the pressure and impact force from the pillow rod 300 in the vertical direction. When the vehicle encounters bumpy road conditions or emergency braking, acceleration, etc. during driving, the connection structure of the deep groove and the locking plate can work together to evenly distribute external forces to the entire headrest structure, greatly enhancing the overall stability and reliability of the headrest, providing continuous and stable support for the passenger's neck.
