Title:
CAB FRAME, CAB AND ENGINEERING VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/155553
Kind Code:
A1
Abstract:
A cab frame, a cab and an engineering vehicle. The cab frame comprises a support framework (1). The support framework (1) comprises a bottom frame (11), a top frame (12) and a four-upright-column structure (13) supported between the bottom frame (11) and the top frame (12). The four-upright-column structure (13) comprises two front upright columns (131) and two rear upright columns (132). The internal size of the cab frame (10) increases along the bottom-to-top direction. The cab frame is configured as a big-end-up structure supported by the four upright columns, and accordingly the cab may simultaneously have smaller dimensions on the bottom potion, larger dimensions on the top portion and few upright columns, thereby reducing obstruction of the field of view caused by bottom plates and the upright columns, and providing sufficient head room for an operator, thus being able to expand the field of view of the cab and improve the comfort of driving.
