[0062] Embodiment 2: As a further improved solution or a side-by-side solution or an optional independent solution, the seat back panel 10 contains fixing holes below, when the half part 14 of the back panel and the lower part 18 of the back panel hang down naturally, the lower part Fixing screws 20 fix the rear panel insert 17 to the seat back panel 10 . The substantive technical effect and realization process of the technical solution here are as follows: Based on the first embodiment, when isolation is not performed, it is a specific fixing method and structure, and similar implementation methods are described in this article. within the scope of patent protection.

[0063] Embodiment 3: As a further improved solution or a side-by-side solution or an optional independent solution, the rear panel half 14 and the rear panel lower half 18 respectively include side hanging baffle 1 22 and side hanging baffle 2 23. Make people's seats into a relatively closed space. The substantive technical effect and the realization process of the technical solution here are as follows: the effect of this embodiment is groundbreaking, it can realize the left and right isolation at the same time of the upper and lower isolation, and the isolation effect is better; at the same time, it has the following two outstanding features: The actual effect of:

[0064] 1. Build a relatively private environment; avoid people who don't know each other from disturbing each other;

[0065] 2. Build a relatively isolated environment; avoid cross-infection. For example, with this structure, this patent is used in the new crown epidemic device, and the vehicle can appropriately i

[0066] Embodiment 4: As a further improved solution or a side-by-side solution or an optional independent solution, the surfaces of the half part 14 of the rear panel and the lower part 18 of the rear panel contain a layer of sponge. The substantive technical effect and the realization process of the technical solution here are as follows: one layer of sponge can play the effect of anti-collision.
