[0034] The utility model provides a side enclosure structure of a vehicle body, see Figure 1 As shown, including:

[0035] Side inner panel 1;

[0036] The roll cage includes a plurality of roll bars 2, and the roll bars 2 are fixed on the side inner plate 1;

[0037] The side enclosure outer plate 3 is fixedly connected to the side enclosure inner plate 1 and together with the side enclosure inner plate 1 forms a roll bar cavity covering the roll bar 2;

[0038] The foam sheet 4 is provided on the side inner panel 1 and is used to fill the gap between the peripheral side wall of the anti-roll bar 2 and the side inner panel 1;

[0039] The foam bracket 5 is arranged on the peripheral side wall of the roll bar 2 to fill the gap between the peripheral side wall of the roll bar 2 and the side outer panel 3.

[0040] See also Figure 1 As shown, the roll bar 2 is a hollow tube. By optimizing the material and the tube shape, the structural weight of the roll bar 2 can be reduced while ensuring high protection strength, thereby reducing the vehicle's unit-kilometer fuel consumption and / or unit-kilometer electricity consumption.

[0041] In some embodiments of the present invention, the roll bar 2 is optionally made of metal. The side inner plate 1 is arranged on the outside of the roll bar 2 and together with the side inner plate 1 forms a roll bar cavity that covers the roll bar 2, which can effectively isolate the entry of external water and dust and protect the material of the roll bar 2.
