Abstract
The utility model provides a head cover of a cab of a heavy truck. The head cover assembly comprises a head cover outer plate and a head cover inner plate located on the inner side of the head cover outer plate. Transverse beams and longitudinal beams which are formed in an integrated mode are integrated on the head cover inner plate. The transverse beams comprise two left transverse beams which are parallel to each other and two right transverse beams which are parallel to each other. The longitudinal beams comprise a left longitudinal beam, a middle longitudinal beam and a right longitudinal beam which are mutually parallel. A top window frame integrated with the two left transverse beams and the two right transverse beams are arranged between the two left transverse beams and the two right transverse beams. Thus, the transverse beams, the longitudinal beams and a top window stamping part are integrated on the head cover inner plate, the number of parts is reduced, and a plurality of stamping parts in the prior art are substituted by one stamping part, and therefore the number of dies is reduced, and manufacture cost of the dies is reduced. Moreover, the head cover inner plate does not need welding so that welding deformation and error accumulation do not exist, and therefore precision of products is improved.
Description
Technical field
The utility model relates to a kind of heavy duty truck, especially a kind of lid of cab of heavy truck assembly.
Background technology
The top cover assembly of heavy duty truck generally is welded by top cover outside plate and roof skeleton.Roof skeleton comprises the blanked part at longeron, crossbeam and position, skylight.After the top cover assembly welding again with the body shell cab body weld together.The shortcoming of this lid of cab assembly is: (1) part is many, causes the accumulated error of welding back product big, and dimensional accuracy of products is restive; (2) welding sequence is many, takes welding processs such as spot welding, CO2 protection weldering, causes the product distortion big in the welding process; (3) top cover assembly adopts spot welding to be connected with body, and solder joint is exposed outside, influences the attractive in appearance of product.Existing in prior technology weak point that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly at the existing in prior technology deficiency, and provides a kind of top cover inner panel integrated lid of cab of heavy truck assembly.
This programme is realized by following technical measures: this lid of cab of heavy truck assembly comprises the top cover outside plate, it also comprises the top cover inner panel of captiveing joint with the top cover outside plate, be integrated with integrated lock piece and longeron on the top cover inner panel, crossbeam comprises two right crossbeams that parallel left crossbeam is parallel with two, longeron comprises the left longeron that is parallel to each other, middle longeron and right vertical beam, between two left crossbeams and two right crossbeams roof window framework integrated with it arranged, the periphery of top cover inner panel has reinforced rib integrated with it.
Above-mentioned top cover inner panel and body shell cab body are bonding, and bonding replacement welding process of the prior art exposes solder joint thereby reduced effectively, have improved presentation quality and the aesthetic property of product.And, the bonding oscillation frequency that improves body shell cab body, because bond area is much larger than the solder joint area, therefore, the intensity of this connection mode is higher.
The side of above-mentioned top cover inner panel is provided with at least three through holes, and the staking nut is installed in the through hole, cooperates with bolt by the staking nut top cover inner panel and body shell cab body are coupled together, to strengthen both Joint strenghts.
Longeron is between the top cover inner panel and roof window framework of a side in above-mentioned.
Left side longeron and right vertical beam run through the top cover inner panel.
Have and both integrated air regulator upper skeleton inner panels between the top cover inner panel of the opposite side relative with above-mentioned middle longeron and the roof window framework.
The periphery of above-mentioned top cover inner panel is connected with strength beam integrated with it by strengthening longeron, strengthens the bulk strength of top cover inner panel by strength beam.
Above-mentioned top cover outside plate and top cover inner panel be fixedly connected as welding.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this lid of cab of heavy truck assembly, be integrated with integrated lock piece and longeron on the top cover inner panel, crossbeam comprises two right crossbeams that parallel left crossbeam is parallel with two, longeron comprises the left longeron that is parallel to each other, middle longeron and right vertical beam, between two left crossbeams and two right crossbeams roof window framework integrated with it arranged, so just with crossbeam, longeron and roof window blanked part integrate on the top cover inner panel, reduced number of parts, a plurality of blanked parts of the prior art are replaced with a blanked part, thereby reduced number of molds, reduced die manufacturing cost, and this top cover inner panel does not need welding, does not have welding deformation and the accumulation of error, thereby has improved the precision of product.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is apparent.
