DETAILED DESCRIPTION

[0021] The application will be further described in detail below with reference to the accompanying drawings.

[0022] The application discloses a car pillow, referring to Figure 1 , 2 , comprising a pillow body 1, the rear end of the pillow body 1 is provided with a rear protrusion which fits the recess of the headrest of a seat, the front end of the pillow body 1 is provided with a front protrusion which fits the neck, and the pillow body 1 is provided with a buffer air bag 2 which corresponds to the shape of the pillow body 1, the buffer air bag 2 can provide elastic support for the pillow body 1 and be more comfortable.

[0023] Referring to Figure 1 , 2 , the buffer air bag 2 is provided with a pressure reduction structure 3 at both ends, the pressure reduction structure 3 comprises an inflatable air bag 31, an abutting claw 32 and an abutting disc 33, the inflatable air bag 31 is accommodated in the side wall of the pillow body 1 and is communicated with the buffer air bag 2, the inflatable air bag 31 can be inflated outward and is arranged in the side wall of the pillow body 1; the abutting disc 33 is fixed to one end of the inflatable air bag 31 relative to the pillow body 1; the abutting claw 32 is fixed to the pillow body 1 and is arranged correspondingly to the inflatable air bag 31, and the abutting claw 32 abuts against the abutting disc 33, so that the inflatable air bag 31 can support the pressure of the buffer air bag 2; when the buffer air bag 2 is subjected to a larger pressure, the abutting claw 32 cannot bear the pressure of the abutting disc 33, then the inflatable air bag 31 is inflated outward, so that the pressure of the buffer air bag 2 is reduced and the buffer air bag 2 is collapsed, and the abutting force on the neck is lost, so that the pressure on the neck is smaller.

[0024] Referring to Figure 1 , 2 , the front side of the buffer air bag 2 is provided with a folding seam 5, the folding seam 5 extends transversely along the front side of the buffer air bag 2, and two sections of the transversely extending end of the folding seam 5 extend towards the four corners of the buffer air bag 2 respectively, when the air bag is collapsed, the transversely extending end of the folding seam 5 is preferentially bent and folded due to its small pressure resistance, and the folding seam 5 extending towards the four corners is bent and folded later due to its strong pressure resistance, so that the neck is opposite to the middle part of the pillow, and is better protected.

[0025] Referring to Figure 2 , 3, the inflation air bag 31 is provided with a pressure relief structure 4, the pressure relief structure 4 further comprises an abutting piston 42, a reset spring 43 and a communication pipe 44, the abutting piston 42 is provided on the pressure relief valve 41 close to one end of the inflation air bag 31 and is slidably connected, the inflation air bag 31 gradually tapers towards the side away from the pillow 1, so that the inflation air bag 31 is misaligned with the abutting piston 42 when it is folded, preventing abutment between them, the abutting piston 42 is connected to the pressure relief valve 41, thereby further relieving the pressure of the buffer structure; the reset spring 43 is fixed to the pressure relief valve 41 and drives the abutting piston 42 to the closed end of the pressure relief valve 41; one end of the communication pipe 44 is communicated with the pressure relief valve 41 and the other end is communicated with the inflation air bag 31; the inflation air bag 31 is provided with an inflation nozzle 6 extending outward at one end of the abutting disc 33, and the buffer air bag 2 after pressure relief is re-pressurized through the inflation nozzle 6.

[0026] The working process of the present application is: when driving daily, the neck touches the buffer air bag 2, and the inflation air bag 31 connected with the buffer air bag 2 keeps the volume unchanged through the limitation of the abutting claw 32, so that the buffer air bag 2 can keep the pressure stable and play a role in shock absorption and support for the neck.

[0027] When the vehicle is impacted by a rear-end impact, the neck hits the buffer air bag 2, and the buffer air bag 2 and the inflation air bag 31 increase the overall pressure, the inflation air bag 31 breaks through the limitation of the abutting claw 32 and expands, so that the gas in the buffer air bag 2 enters the inflation air bag 31, and the buffer air bag 2 pressure becomes small and can be collapsed to absorb energy.

[0028] If the impact pressure is large, the inflation air bag 31 expands to the limit, the side wall of the inflation air bag 31 abuts against the abutting piston 42, the abutting piston 42 loses the sealing of the pressure relief valve 41, and multiple pressure relief valves 41 can quickly deflate, thereby further reducing the pressure of the buffer air bag 2, avoiding the pillow 1 causing large pressure to the neck, and the buffer air bag 2 after pressure relief can be re-inflated through the inflation nozzle 6.

[0029] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
