[0033] Specifically, the cushion body 20 is arranged on the cushion framework 10. On the one hand, the cushion framework 10 can bear the pressure from the human body and evenly distribute the pressure, so as to ensure that the cushion 100 can provide stable support for the user and ensure the overall structural strength and safety of the cushion 100. On the other hand, the cushion body 20 can adapt to the shape of the user's hips and legs and support the user's hips, legs and even the whole body, so as to improve the comfort of the user.

[0034] Considering different needs of users when using the seat, the cushion 100 is further provided with the electric device 30. By selectively arranging different electric devices 30 and controlling the operation of the electric device 30, the needs of the user such as ventilation, heating and the like can be met, and the comfort of the user can be improved.

[0035] It can be understood that the operation of the electric device 30 needs power supply. By arranging the battery box assembly 40 at the rear end of the cushion framework 10, and making the battery box assembly 40 include the battery box 41, the battery 42 and the magnetic charging connector 441.

[0036] Specifically, the battery 42 is detachably arranged in the battery box 41, and the battery 42 is electrically connected with the electric device 30. In this way, the built-in battery 42 can be realized, the position of the external power supply of the cushion 100 can be limited, and the power supply demand of the cushion 100 in different occasions can be met.

[0037] And the battery box assembly 40 includes the magnetic charging connector 441, and the magnetic charging connector 441 is electrically connected with the battery 42. In this way, the user can electrically connect the external power supply through the magnetic charging connector 441, charge the battery 42, or supply power to the electric device 30, so as to improve the endurance of the cushion 100 and be more environmentally friendly and energy-saving.

[0038] It should be noted that the magnetic charging connector 441 realizes the stable connection between the cushion 100 and the external power supply through the interaction between the magnetic materials. In this way, not only can the operation experience of the user be simplified, the electrical connection between the cushion 100 and the external power supply is facilitated, but also when an accident occurs, such as excessive pulling, as long as the pulling force exceeds the threshold of the magnetic charging connector 441, the magnetic connection will be automatically disconnected, which can avoid possible damage and improve the safety of use.

[0039] Therefore, by making the battery box assembly 40 include: the battery box 41, the battery 42 and the magnetic charging connector 441, the battery 42 is detachably arranged in the battery box 41, the battery 42 is electrically connected with the electrical device 30, and the magnetic charging connector 441 is electrically connected with the battery 42.
