Detailed description of the invention
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in Figures 1 to 5, lid of cab structure of the present utility model, comprises top cover outside plate 1 and roof skeleton 2; Top cover outside plate 1 comprises front shroud 3, back shroud 4, left cover 5, right cover plate 6 and inter panel 7; Front shroud 3, back shroud 4, left cover 5 are all connected with inter panel 7 with right cover plate 6; Roof skeleton 2 comprises sinciput longeron 8, roof panel cross member 9, middle top longeron 10, rear top longeron 11 and middle parietal bone frame 12; Sinciput longeron 8 is connected with the front end of middle parietal bone frame 12, and roof panel cross member 9 is connected with the both sides of middle parietal bone frame 12 respectively, and middle top longeron 10 is connected with the rear end of middle parietal bone frame 12, and rear top longeron 11 is connected with middle top longeron 10 is vertical; Top cover outside plate 1 snaps onto the upper end of roof skeleton 2, and is welded and fixed with roof skeleton 2.Lid of cab structure of the present utility model, by optimizing the formation of lid of cab structure, being divided into top cover outside plate 1 and roof skeleton 2 two parts, and being increased the intensity of lid of cab structure by modularization assemble structure by lid of cab structure.Inter panel 7 wherein on top cover outside plate 1 combines with the middle parietal bone frame 12 on roof skeleton 2, a part of lid of cab pressure can be born, owing to adopting modularization assemble welding, stress during major part pressurized can from roof skeleton 2 all around four direction disperse, and stress to be passed on body shell by the crossbeam on roof skeleton 2 and longeron.Because stress is not concentrated in a bit to produce lid of cab structure and destroys, so when lid of cab pressurized, can play a protective role to driver and crew.Modular splicing structure can dispersive stress faster in addition, so suitably reduce the requirement of strength of single building block, so just can the common sheet metal component of choice for use, thus the material requirement reduced sheet metal component, rear top longeron for main load then adopts high strength steel, so both by the assembled intensity increasing lid of cab structural entity, the cost of exploitation material and mould can be additionally reduced, effectively raised production efficiency.
As shown in Figure 3, the side, lower end, the back side of back shroud 4 is provided with streamlined reefer housing adapter plate 13, and back shroud 4 is by being fixedly connected with streamlined reefer housing through the bolt of streamlined reefer housing adapter plate 13.Utilize streamlined reefer housing adapter plate 13 streamlined reefer housing can be fixedly attached on top cover outside plate 1, when streamlined reefer housing is subject to the stress influence of wind, stress can be delivered on top cover outside plate 1 by back shroud 4, then be passed on roof skeleton 2 by top cover outside plate 1, Stress transmit is on body shell the most at last, so just can ensure that streamlined reefer housing because of stressed excessive and produce damaged or fracture, can not effectively raise the service life of streamlined reefer housing.
It can also be seen that from Fig. 3, the outer face front lower ends of right cover plate 6 is provided with rearview mirror mounting plate 14, right cover plate 6 is by being fixedly connected with back mirror through the bolt of rearview mirror mounting plate 14, in the middle part of the outer face of right cover plate 6, be also provided with inlet channel adapter plate 15, right cover plate 6 is by being fixedly connected with inlet channel through the bolt of inlet channel adapter plate 15 simultaneously.Back mirror is very important parts for vehicle driving safety, and back mirror be easily subject to vehicle vibration stress impact and produce rock, when back mirror is fixedly attached on top cover outside plate 1 by rearview mirror mounting plate 14, the stress that back mirror is subject to also can be delivered on body shell by top cover outside plate 1 and roof skeleton 2, so just can ensure that back mirror can not be subject to the impact of vibration stress in vehicle travel process, actv. improves the service life of back mirror.In like manner, inlet channel is owing to needing the air providing burning to driving engine, also the stress influence of wind during air inlet can be subject to, if the fixing insecure or uneven easy generation of stress dispersion loosens, the work of driving engine can be affected time serious, when inlet channel is connected to top cover outside plate by inlet channel adapter plate 15, the stress that air inlet produces can be passed on body shell by top cover outside plate 1 and roof skeleton 2, actv. improves the intensity of inlet channel, increase the service life of inlet channel, ensure the normal work of driving engine.
As shown in Figure 4, the end of sinciput longeron 8 is connected with " L " shape air regulator cross-beam connecting plate 16, and air regulator cross-beam connecting plate 16 is connected with air regulator crossbeam by welding.Front Windshield is the bearing surface of vehicle forefront, need to bear vehicle front wind-force suffered in the process of moving, usually suffered stress can be born by air regulator crossbeam, long-term stressed meeting makes the intensity of air regulator crossbeam decline, and can by the Stress transmit suffered by air regulator crossbeam on roof skeleton 2 by air regulator cross-beam connecting plate 16, then roof skeleton 2 is passed through by Stress transmit on body shell, stress can be made progressively to disperse by transmitting layer by layer, can reduce thus and make air regulator crossbeam produce distortion because stress concentrates, and then minimizing front windshield glass produces the possibility of breaking because of discontinuity, the service life of effective raising air regulator.
In addition, as shown in Figure 4, reinforced company's fishplate bar 17 is welded with at rear top longeron 11 and the junction of middle top longeron 10.Owing to being vertical connection between rear top longeron 11 and middle top longeron 10, so when stress being disperseed after middle parietal bone frame 12 is stressed, easily concentrate at the junction generation stress of rear top longeron 11 and middle top longeron 10, time has grown easy generation distortion or fracture, utilize reinforced company's fishplate bar 17 can improve the junction intensity of rear top longeron 11 and middle top longeron 10, stress can be transmitted to vehicle body smoothly by reinforced company's fishplate bar 17, and then improve the service life of cap structure entirety.Meanwhile, be also provided with top cover back wall connecting panel 18 at the end of rear top longeron 11, rear top longeron 11 is fixedly connected with back shroud 4 by the bolt through top cover back wall connecting panel 18.Utilize top cover back wall connecting panel 18 rear top longeron 11 and back shroud 4 can be fixed together, owing to being also connected with streamlined reefer housing adapter plate 13 on back shroud 4, rear top longeron 11 and back shroud 4 are bolted, and are conducive to installing streamlined reefer housing and keeping in repair, and improve convenience.
Structure of the present utility model, feature and action effect is described in detail above according to illustrated embodiment; the foregoing is only preferred embodiment of the present utility model; but the utility model does not limit practical range with shown in drawing; every change done according to conception of the present utility model; or be revised as the Equivalent embodiments of equivalent variations; do not exceed yet specification sheets with diagram contain spiritual time, all should in protection domain of the present utility model.
