For example, the roof panel 400 may be fixed to at least one of the cross member 320H of the first support bracket 321 and the cross member 320H of the second support bracket 322. It should be noted that when the roof panel 400 is directly fixedly connected to the top of the first and

second support brackets

321 and 322, the connection beam 330 described above in connection with fig. 2 may be omitted.

In an exemplary embodiment, the roof panel 400 may also be fixed to a third support frame 323, for example, an upper cross member 323U fixed to the third support frame 323. The roof panel 400 may include one roof panel, but the number of the roof panels 400 is not limited thereto, and for example, the roof panel 400 may be formed by joining two or more roof panels. In some embodiments, the roof panel 400 may include a roof panel corresponding to the top of the cockpit and a roof panel corresponding to the top of the cargo box, and the two roof panels may or may not be coplanar with each other.

510P and 520P being disposed between the second and third support frames 322 and 323.

As shown in FIG. 1, in an exemplary embodiment, the body 10 may also include a bulkhead 370. The partition 370 is provided on the second support bracket 322 for forming a cabin with the left door 510G, the right door 520G, and the front floor 210.

Referring to FIG. 8, and in conjunction with FIG. 2, in an exemplary embodiment, the body 10 may also include a tailgate 380. A tailgate 380 is provided on the third support frame 323 for forming a cargo box with the bulkhead 370, the left side panel 510P, the right side panel 520P, and the rear floor 220. In the present embodiment, the vehicle 1 may be a truck, in particular a mini-truck for logistics transport, such as an express delivery vehicle.

In the present embodiment, the vehicle body 10 includes a center sill 100, a floor pan 200, and a support frame 300, and the center sill 100, the floor pan 200, and the support frame 300 form a self-supporting structure. That is, the vehicle body 10 is a monocoque body in the present embodiment. By load-carrying vehicle body is meant that the vehicle body carries the entire vehicle body, the vehicle body load being transmitted to the wheels via the suspension assembly. The bearing type vehicle body has the advantages of high utilization rate of the internal space, light weight, low gravity center, high stability and low energy consumption. The front frame and the rear frame of the bearing type vehicle body can be collapsed when a collision accident happens so as to absorb the impact force and protect the driver and passengers in the vehicle, thereby having high safety.

According to yet another aspect of the present invention, the vehicle 1 includes a body 10 and a chassis 20. The vehicle body 10 includes a floor 200 and a support frame 300. The tray 20 includes a generally longitudinally extending center keel 100. The support frame 300 and the floorboard 200 are fixed to the center sill 100, the support frame 300 includes a bracket 310 and a support bracket 320, the bracket 310 is fixed to the center sill 100, and the support bracket 320 is fixed to the bracket 310.

Fig. 9 schematically shows a perspective view of a chassis according to an embodiment of the invention. As shown in fig. 9, the chassis 20 includes a center runner 100 and a wheel pair 600 secured to the center runner 100. Specifically, the wheel-set 600 may include a front wheel-set 610 and a rear wheel-set 620. The front wheel pair 610 is secured to the front end of the center keel 100 and the rear wheel pair 620 is secured to the rear end of the center keel 100.

In this embodiment, the chassis 20 includes a center keel 100, and the support frame 300 and the floor pan 200 are fixed to the center keel 100. That is, in the present embodiment, the vehicle body 10 is a non-self-supporting vehicle body. In the non-load-bearing vehicle body, the chassis includes a center keel to have high strength. Because the center console is rigid and can absorb and resist the torsional force well, the influence that the non-bearing type automobile body receives when the vehicle passes uneven road surface is reduced remarkably. Besides the buffering and vibration absorbing functions of the tire and the suspension system on the whole vehicle, a damping material can be arranged between the central keel and the vehicle body to play a role in assisting in buffering, properly absorbing torsional deformation of the vehicle frame and reducing noise, so that the service life of the vehicle body is prolonged, and the riding comfort is improved. The chassis and the vehicle body can be assembled separately and then assembled together, which simplifies the assembly process and facilitates organization of specialized cooperation. Further, the vehicle components are mounted on the center console, thereby facilitating replacement or repair of the components.

It should be noted that the description of the remainder of the vehicle above with respect to fig. 1-8 applies to this embodiment, except that the chassis 20 includes a center keel 100, and therefore will not be described again.

The foregoing description is only exemplary of the preferred embodiments of the invention and is illustrative of the principles of the technology employed. It will be appreciated by those skilled in the art that the scope of the invention herein disclosed is not limited to the particular combination of features described above, but also encompasses other arrangements formed by any combination of the above features or their equivalents without departing from the spirit of the invention. For example, the above features and (but not limited to) features having similar functions disclosed in the present invention are mutually replaced to form the technical solution.
