Abstract
The utility model relates to a car cab rear wall reinforcing structure. The reinforcing structure is composed of an outer shell and an internal structure, the outer shell comprises a shell body, a rear window is arranged at the upper end of the shell body, and reinforcing bars are arranged at the lower end of the shell body. The internal structure is provided with a first connecting transverse beam and a second connecting transverse beam corresponding to the upper end and the lower end of the rear window. The internal structure is provided with side body connecting beams corresponding to the positions nearby the left side and the right side of the rear window respectively, and connecting portions used for a floor assembly are arranged at the lower ends of the side body connecting beams. Y-direction flanges used for being in screw joint with a side body assembly are arranged on the end portion of the first connecting transverse beam. Welding extending portions used for being welded to the side body assembly are arranged on the end portion of the second connecting transverse beam. According to the car cab rear wall reinforcing structure, rigidity and strength of a cab are improved, better safety guarantees can be provided for passengers in a car when the car is overturned, the weight of parts is reduced through the reasonable structure, therefore, vibration and noise of the cab are lowered, and riding comfort is improved.
Description
Technical field
The utility model belongs to the technical field of automotive body structure, and in particular, the utility model relates to a kind of automobile cab back wall and strengthens structure.
Background technology
In prior art, in cab structure in the time there is roll-over accident, operator's compartment can not provide good supporting role, thereby cause the injury to occupant, major cause has following 3 points: 1: back wall assembly is connected without closed section with floor assembly, cannot bear larger X to Z-direction load, the Rigidity and strength of structure a little less than; 2: back wall assembly only depends on flange to be connected with side wall assembly, cannot bear larger Y-direction load, a little less than the Rigidity and strength of structure; 3: on rear end panel, inner panel area is larger, and structure is heavier.
Utility model content
The above-mentioned technical matters existing in order to solve prior art, the purpose of this utility model is to provide a kind of automobile cab back wall to strengthen structure.
Automobile cab back wall described in the utility model is strengthened structure, its Width along vehicle vertically arranges, and as the dividing plate of rear cabin, described reinforcement structure is made up of shell and inner structure, described shell comprises housing, housing upper end is provided with rear window window, and lower end is provided with reinforced rib; It is characterized in that: corresponding to the top and bottom place of described rear window window, described inner structure has the first connecting cross beam and the second connecting cross beam; Near left side and right side corresponding to described rear window window, described inner structure also has respectively gusset tie-beam, the lower end of described gusset tie-beam have for the connecting portion of floor assembly; Wherein, the end of described the first connecting cross beam is provided with the Y-direction flange being spirally connected for side wall assembly; The end of described the second connecting cross beam is provided with the welding extension with side wall assembly welding.
Wherein, on described the first connecting cross beam, the second connecting cross beam and gusset tie-beam, be provided with multiple auxiliary holes.
Automobile cab back wall described in the utility model is strengthened structure and is compared with prior art had following beneficial effect:
Automobile cab back wall of the present utility model is strengthened structure, improve the Rigidity and strength of operator's compartment, in the time of automobile generation roll-over accident, better guaranteed passenger's safety, and by the weight of rational structure decrease part, thereby improve vibration and the noise of operator's compartment, improve ride comfort sense.

The specific embodiment
Below with reference to embodiment and accompanying drawing, automobile cab back wall described in the utility model being strengthened to structure is described in further detail.
Embodiment 1
As shown in Figure 1, automobile cab back wall described in the present embodiment is strengthened structure, its Width along vehicle vertically arranges, and as the dividing plate of rear cabin, described reinforcement structure is made up of shell 10 and inner structure 20, described shell 10 comprises housing, and housing upper end is provided with rear window window 11, and lower end is provided with reinforced rib 12; And corresponding to the top and bottom place of described rear window window 11, described inner structure has the first connecting cross beam 21 and the second connecting cross beam 22; Near left side and right side corresponding to described rear window window 11, described inner structure also has respectively gusset tie-beam 23, the lower end of described gusset tie-beam 23 have for the connecting portion 24 of floor assembly; Wherein, the end of described the first connecting cross beam 21 is provided with the Y-direction flange 25 being spirally connected for side wall assembly; The end of described the second connecting cross beam 22 is provided with the welding extension 26 with side wall assembly welding.On described the first connecting cross beam 21, the second connecting cross beam 22 and gusset tie-beam 23, be provided with multiple auxiliary holes 27.
As shown in Figure 2-5, in reinforcement structure described in the utility model, end at the first connecting cross beam increases Y-direction flange (referring to section F-F), with bolts with side wall assembly part 3,4,5, thereby the coupling stiffness of upper part and side wall assembly after improving, improve the object of operator's compartment opposing Y-direction load, and then improve the object of cab structure Rigidity and strength.The end of the second connecting cross beam is provided with the welding extension (referring to section E-E) with side wall assembly welding, with side wall assembly part 3,5 weld togethers, thereby improve the coupling stiffness of bottom part of rear boarding and side wall assembly, improve the object of operator's compartment opposing Y-direction load, and then improve the object of cab structure Rigidity and strength.And back wall bottom column section and floor assembly part 1,2,6,7 can reach the object (referring to section D-D) of closed section, improve the object of operator's compartment opposing Z-direction load, and then reach the object that improves cab structure Rigidity and strength.By above loss of weight and strengthening measure to operator's compartment, actv. improve the strength and stiffness of operator's compartment, make better to guarantee occupant's safety in the time that operator's compartment has an accident, and improve travelling comfort.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
