For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] Referring to Figures 1 to 3 , a structure schematic diagram of a headrest assembly is shown, the headrest assembly can specifically include: a headrest 10, a soft pillow 20, a heating element 21 and an electrical connector 30; the soft pillow 20 is detachably connected to the headrest 10; the heating element 21 is arranged in the soft pillow 20, and the soft pillow 20 is provided with an electrical connector 22, which is electrically connected to the heating element 21; the electrical connector 30 is arranged on the headrest 10, and the electrical connector 22 of the soft pillow 20 is detachably connected to the electrical connector 30.

[0044] In the embodiment of the present application, through detachable connection of the power connection part 22 of the soft pillow 20 and the power connection seat 30 arranged on the headrest 10, on the basis that the soft pillow 20 can realize the heating function through the heating element 21, the user has better use experience, and the detachable connection of the soft pillow 20 and the headrest 10 part can also be realized, which is convenient for disassembling, cleaning and replacing the soft pillow 20. When the heating function of the headrest assembly is needed, the heating element 21 realizes circuit conduction through the power connection part 22 and the power connection seat 30, and converts electrical energy into heat energy. When the soft pillow 20 needs to be disassembled for cleaning and replacement, one end of the soft pillow 20 can be disassembled from the headrest 10, and the power connection part 22 at the other end of the soft pillow 20 is disconnected from the power connection seat 30, so that the soft pillow 20 and the headrest 10 are disassembled, which is simple in structure and convenient to operate, so that the headrest assembly has both heating function and detachable convenience. The problem that the soft pillow 20 with heating function is difficult to realize detachable connection due to the need to arrange a connection wire harness is solved.

[0045] For example, in the embodiment of the present application, as shown in Figure 7 The soft pillow 20 can include a cover sleeve 26, a pillow core 25 and a heating element 21. The heating element 21 can be connected to the front side of the pillow core 25, i.e. the side close to the human head and neck, by sewing or the like. The cover sleeve 26 covers the outer periphery of the pillow core 25 and the heating element 21, and is used to protect the pillow core 25 and the heating element 21.

The first buckle can be a metal buckle, and the second buckle 31 can also be a metal buckle. The first buckle is connected to the second buckle 31, which can realize the circuit conduction between the heating element 21 in the soft pillow 20 and the electrical connecting element 40 in the headrest 10. For example, the number of the first buckles can be one, three, four, etc. The specific number of the first buckles can be set according to actual needs, and the present application does not limit the specific number of the first buckles. Correspondingly, the number of the first buckles can be one, three, four, etc. The specific number of the second buckles 31 can also be set according to actual needs, and the present application does not limit the specific number of the second buckles 31.

For example, the second fixing belt 24 can be arranged on the cover sleeve 26 of the soft pillow 20. The detachable connection between one end of the soft pillow 20 and the headrest 10 is realized through the second fixing belt 24, which is simple in structure and easy to operate.

[0050] For example, in the embodiments of the present application, Velcro can be arranged on the second fixing belt 24. After the second fixing belt 24 is connected around the fixing ring 11, the Velcro is used for adhesive fixing, which further improves the operation convenience and fixing reliability. The specific setting position of the Velcro can be set according to the size and shape of the fixing ring 11, and the present application does not limit the specific setting position of the Velcro.

[0051] In the embodiments of the present application, optionally, as shown in Figure 3 The headrest assembly further includes an electrical connecting element 40. The electrical connecting element 40 is arranged in the headrest 10 and extends out of the headrest 10.
