In use, rear passengers can control the first drive device 5 to drive the first transmission structure 2 to flip relative to the support frame 3 by continuously pressing the switch component, thereby realizing the flipping and movement of the heating component 1. By controlling the second drive device 6 to drive the support frame 3 to rotate in the left and right directions, the horizontal angle of the heating component 1 can be adjusted, thereby providing all-round and rapid heating of the passengers' knees, calves, and feet, improving the comfort and experience of rear passengers.

[0038] Optionally, the first transmission structure 2 includes: a first transmission shaft 21 rotatably connected to the support frame 3; wherein the first transmission shaft 21 is rotatably connected to the support frame 3 by small-diameter positioning pins on both sides; a configuration plate is provided on the first transmission shaft 21; the configuration plate 22 has a semi-circular cross-section and is an overall elongated structure; the front horizontal part of the configuration plate 22 is connected to the mounting plate 24 by a support rod 23; a heating component 1 is fixedly provided on the front end face of the mounting plate 24; a reversing gear 25 that is transmitted and connected to the first driving device 5 is fixedly provided on one side of the configuration plate 22 on the first transmission shaft 21; the advantage of this design is that the design of the configuration plate 22 ensures the stability of the first transmission shaft 21 during rotation.

[0041] Specifically, the first drive device 5 is rotatably connected to the support frame 3 through the first mounting hole and meshes with the flip gear 25, thereby enabling the first transmission structure 2 to rotate relative to the support frame 3.

[0042] Optionally, the first driving device 5 includes: a first transmission rod 51 rotatably connected to the support frame 3 and a first drive motor 52 drivenly connected to the first transmission rod 51; wherein, the upper end of the first transmission rod 51 extending out of the first mounting hole is provided with a first transmission tooth 53 that meshes with the reversing gear 25; the lower end of the first transmission rod 51 is provided with a second transmission tooth 55 that meshes with the output shaft of the first drive motor 52; wherein, the outer surface of the output shaft of the first drive motor 52 is provided with helical teeth that mesh with the second transmission tooth 55; the bottom of the first transmission rod 51 is rotatably connected to the base plate 7 through a support column 54; the first drive motor 52 is fixed on the base plate 7.

The first transmission at the upper end of the first transmission rod 51 meshes with the reversing gear 25, thereby driving the first transmission shaft 21 to rotate and thus driving the heating component 1 to flip.

[0044] Optionally, a friction-reducing sleeve 32 is provided inside the first mounting hole; wherein the first transmission rod 51 passes through the friction-reducing sleeve 32; the upper and lower edges of the friction-reducing sleeve 32 extend outward along their circumferential sides and are provided with stop edges 33 that fit against the surface of the support frame 3. Preferably, the friction-reducing sleeve 32 is a spherical sliding bearing.
