the frame module is rotatably connected with the rear seat module so as to enable the rear seat module to be in a closed state or an open state under the rotating action; when the rear seat module is in a closed state, the rear seat module abuts against the upper end of the inner side mudguard;

the pedal module fixedly connected with the lower end of the inner side mudguard is arranged in a concave manner towards the direction close to the ground, so that the distance from the seat surface of the rear seat module in the closed state to the pedal surface of the pedal module is kept within a comfortable distance range.

2. A vehicle body structure as defined in claim 1, wherein:

the distance range from the pedal module to the ground is 410-445 mm.

3. A vehicle body structure as defined in claim 1, wherein:

the frame module also comprises a connecting transverse plate which is fixedly connected with the inner side of the frame;

the lower end of the connecting transverse plate is connected with the upper end of the inner side mudguard;

the front end of the connecting transverse plate is rotatably connected with the rear seat module.

4. A vehicle body structure as defined in claim 1, wherein:

the inside fender includes: a first inboard fender and a second inboard fender; the first inner side fender is positioned at the left end of the frame, and the second inner side fender is positioned at the right end of the frame;

the frame module further comprises a bottom plate which is arranged between the first inner side mudguard and the second inner side mudguard and is connected with the first inner side mudguard and the second inner side mudguard to form a storage space.

5. A cabin structure according to claim 4, characterized in that:

the storage space is provided with an object taking opening, and the opening direction of the object taking opening faces the rear-row seat module;

when the rear seat module is in a closed state, the rear seat module is used for covering the fetching port;

when the rear seat module is in an opening state, the fetching opening is exposed at the front end and the upper end of the storage space.

6. A cabin structure according to claim 4, characterized in that:

the lower end of the inner side mudguard is provided with a first bending part and a second bending part;

the first bending part extends towards the direction of the pedal module and is fixedly connected with the pedal module;

the second bending part extends towards the direction of the bottom plate and is fixedly connected with the bottom plate.

7. A vehicle body structure as defined in claim 1, wherein:

the upper end of the inner side mudguard is provided with a bearing part;

the rear seat module comprises a propping part, and the propping part is arranged at the left end and the right end of the rear seat module and props against the bearing part when the rear seat module is in a closed state.

8. A vehicle body structure as defined in claim 7, wherein:
