DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] An embodiment of the present utility model is as follows Figure 1 and Figure 2 As shown, a first adjustment mechanism 5 is provided on the top of the base 4, and a headrest rod 41 is provided below the base 4. The headrest body includes a connecting plate 7 located above the first adjustment mechanism 5. On the top of the connecting plate 7, a front shell 1 and a rear shell 2 are connected to each other. A through hole is provided between the fitting surfaces of the front shell 1 and the rear shell 2, and a second adjustment mechanism 6 is provided in the through hole. A neck support pillow 3 is provided on one side of the front shell 1 away from the rear shell 2. The outside of the headrest body is covered with a headrest cotton cover. Through the two groups of adjustment mechanisms, fine adjustment of the horizontal position, height position and angular position of the car seat headrest is realized, meeting the usage requirements of different people, and improving the comfort, applicability and flexibility during use.

[0023] As Figure 5 shown, the first adjustment mechanism 5 includes a slide rail assembly provided between the base 4 and the connecting plate 7. At least two groups of slide rail assemblies are provided and installed in parallel. The slide rail assembly installed on the base is a guide rail structure, and the slide rail assembly installed at the bottom of the connecting plate 7 is a slider structure matching the guide rail structure. The two are mutually clamped and the stroke of the guide rail structure is greater than the length of the slider structure. Limit blocks are provided at both ends of the slide rail assembly in the length direction to prevent the headrest body from exceeding the stroke. The slide rail assembly is used for fine adjustment of the horizontal position of the headrest, and the adjustment range is the difference between the guide rail structure and the slider structure.

[0024] A locking mechanism 42 is installed on the outer side of the base 4 of the slide rail assembly. The locking mechanism 42 includes a sleeve fixed on the base 4 and a pressing rod movably arranged in the sleeve. A return spring is installed between the pressing rod and the sleeve. The locking mechanism has a rebounding effect to realize point-moving locking and limiting of the slide rail assembly.

[0025] As Figure 2 and Figure 3 shown, the front shell 1 and the rear shell 2 are fixedly connected by bolts. The front shell 1 is provided with outwardly extending flanges 11 on both sides of the neck support pillow 3. One end of the neck support pillow 3 close to the front shell 1 is provided with a guide rod. The front shell 1 is provided with a concave surface. The guide rod of the neck support pillow passes through the concave surface and is connected to the front shell for fixing the neck support pillow, which is convenient for disassembly and assembly.

[0026] As Figure 6 shown, the second adjustment mechanism 6 includes a rotating shaft 61 provided in the through hole. A shaft sleeve 62 is sleeved on the middle section of the rotating shaft 61. A fixing rod 63 is provided at the bottom of the shaft sleeve 62 and is connected to the connecting plate 7. The shaft sleeve 62 is movably arranged in the through hole between the front shell 1 and the rear shell 2. One end of the rotating shaft 61 is provided with a rebounding structure. By the driver's raising and lowering of the head, a force is applied to the headrest, so that the headrest body makes an angular fine adjustment with the rotating shaft as the rotation center. The rebounding structure is used for the reset of the headrest structure.

[0027] As Figure 4As shown, a clamping block 64 is provided on the rotating shaft 61, and a clamping groove 21 corresponding to the clamping block 64 is formed on the arc surface of the through hole of the rear shell 2. The rotating shaft 61 is connected to the headrest body through the clamping block 64 and the clamping groove 21. The shaft sleeve 62 provides positioning for the rotating shaft 61, and the headrest body can rotate around the rotating shaft after an external force is applied to it. As Figure 1 shown, after the front shell 1 and the rear shell 2 are installed, there is a gap at the bottom. The angle adjustment range of the headrest body is the distance between the front shell 1 and the fixing rod 63, and the distance between the rear shell 2 and the fixing rod 63.

[0028] The guide rod on the back of the neck pillow 3 is connected to the front shell 1. The neck pillow 3 is of an arc-shaped structure, and massage blocks are arranged at the position where the concave surface is close to the human neck to improve the comfort of the driver.

[0029] The working principle of this embodiment: The driver manually inserts the headrest rod into the top of the car seat, adjusts the height of the headrest according to his own needs, locks the height position after adjustment, adjusts the angle of the car seat so that the headrest is in a more comfortable position, manually presses the locking mechanism, makes fine adjustments to the front and back of the horizontal position of the headrest and locks it, and makes fine adjustments to the angle of the headrest through the up and down movements of the driver during driving.

[0030] The following points need to be explained: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the communication inside two components, and can be directly connected.
