[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 7 and attached Figure 8As shown, a car neck pillow structure with Y-axis angle adjustment and locking function includes an arc-shaped support 1 connected above the car seat. The support 1 has symmetrically hinged blades 2 at its left and right ends, and the two blades 2 are arc-shaped. The two blades 2 can rotate relative to each other or in opposite directions along the Y-shaped structure. The support 1 has symmetrically provided sleeves 6 at its left and right ends. At the opposite ends of the two blades 2, there are sleeves 7 that cooperate with sleeves 6. A rotating shaft 8 is passed through both sleeves 6 and sleeves 7 on the same side. Under the action of the rotating shaft 8, the two blades 2 can be rotated and adjusted by external force.

[0032] A locking device 3 is provided on the support 1 to automatically position the rotation of the two blades 2, and an adjustment device 4 is also provided to unlock the locking device 3. After the locking device 3 is unlocked, the two blades 2 automatically rotate to reset. A torsion spring 23 is wound on the rotating shaft 8 to reset the blades 2. One end of the torsion spring 23 abuts against the sleeve 6 and the other end abuts against the sleeve 7. When the locking of the two blades 2 is released, the two blades 2 automatically rotate to reset under the reaction of the torsion spring 23.

[0033] Combined with appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the locking device 3 includes two movable seats 9 that are disposed on the back of the bearing seat 1 and can slide in the direction of the blades 2 on both sides. The movable seats 9 are provided with positioning teeth 10. The two blades 2 are provided with several locking teeth 11 that cooperate with the positioning teeth 10 at their opposite ends. Rotating the blades 2 causes the positioning teeth 10 to engage with different locking teeth 11. The number of locking teeth 11 is three. The adjusting device 4 is used to adjust the sliding position of the movable seats 9 and thus control the engagement or disengagement of the positioning teeth 10 and the locking teeth 11. A return spring 19 is fixedly provided between the movable seats 9 and the bearing seat 1 along its sliding direction.

[0034] When the two blades 2 are rotated for adjustment, the positioning teeth 10 and the locking teeth 11 work together to block the sleeves 7 at both ends. At the same time, the moving seat 9 and the return spring 19 work together to automatically lock the two blades 2.

[0035] The three positioning teeth 10 allow for switching between three rotation angles on the two blades 2. When the locking tooth 11 abuts against the end face of the last positioning tooth 10, it is in the first position, which is the initial state, and the neck pillow is in a flat position with both wings flat. When the locking tooth 11 abuts against the end face of the middle positioning tooth 10, it is in the second position, and the neck pillow is in a slightly curved position with both wings. When the locking tooth 11 abuts against the end face of the foremost positioning tooth 10, it is in the third position, and the neck pillow is in a wrapping position with both wings. This allows for adaptive adjustment of the neck pillow according to the user's needs, improving the practicality of the device.

[0036] Combined with appendix Figure 2 Appendix Figure 4 and attached Figure 5 As shown, the adjustment device 4 includes a drive member 12 located at the ends of two movable seats 9 and slidably mounted on the support seat 1. The two movable seats 9 are provided with a sliding groove 15 that can pass through the drive member 12. The two drive members 12 are provided with a wedge-shaped surface 16 along their height direction. The inner walls of the two sliding grooves 15 are provided with a mating surface 17 that matches the wedge-shaped surface 16. The support seat 1 is provided with a transmission device 5 that enables the two drive members 12 to slide synchronously.

[0037] The transmission device 5 includes a button 13 located between two driving members 12 and slidably mounted on the support seat 1. The bottom surface of the button 13 is provided with an inverted U-shaped frame 14. The two ends of the U-shaped frame 14 are respectively connected to the corresponding driving members 12, and a reset spring 24 is provided between the button 13 and the support seat 1.

[0038] When it is necessary to unlock the two blades 2, press down button 13 to drive the U-shaped frame 14 to move downward, and then drive the drive components 12 at both ends to move downward synchronously, so that the wedge surfaces 16 and mating surfaces 17 at both ends are engaged, and the moving seats 9 at both ends are adjusted to slide relative to each other, thereby separating the locking teeth 11 and the positioning teeth 10, and releasing the positioning of the blades 2 at both ends.

[0039] Combined with appendix Figure 1 and attached Figure 6As shown, the back of the support seat 1 is detachably provided with a rear end cover 18 covering the adjustment device 4, and a second return spring 24 is fixedly connected between the button 13 and the rear end cover 18. Under the action of the second return spring 24, the button 13 can be automatically reset after the external force is removed. The support seat 1 is detachably provided with a connecting seat 20 covering the locking device 3. The connecting seat 20 is provided with a detachable support seat 21. The support seat 21 is telescopically connected to the mounting seat 22, and the mounting seat 22 is connected to the positioning rod of the headrest above the car seat. The telescopic function of the support seat 21 allows the support seat 1 to be slidably adjusted back and forth during use, so that this neck pillow can be suitable for the needs of different people.

[0040] In the specific implementation of this utility model, the mounting base 22 is first connected to the positioning rod of the headrest above the car seat. Then, the support base 21 is extended and retracted according to the use needs, while the bearing base 1 and the two blades 2 are extended and retracted. Then, the two blades 2 are rotated relative to each other to adjust the neck pillow to the second or third position. During the rotation adjustment process, the locking device 3 automatically positions the two blades 2.

[0041] When it is necessary to reset the two blades 2 to the first position, the positioning of the two blades 2 is first released by the adjustment device 4. Then, under the reaction of the torsion spring 23, the two blades 2 are automatically rotated to reset, thereby improving the ease of operation of the device.

[0042] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
