The novel front cabin skeleton structure of the electric automobile facilitates mounting of a power assembly and electrical appliance parts, front cabin space is effectively used, the vibration and impulse loads subjected by a front cabin are isolated or reduced, and the strength and the rigidity of the front cabin skeleton structure are effectively improved.
Description
Technical field
The present invention relates to a kind of novel front cabin skeleton structure, particularly relate to a kind of novel front cabin skeleton structure for power assembly of electric automobile and electric component installation.
Background technology
From automobile invention so far, but more than 100 year time, but look back this period of history, we can see that automobile has been played the part of and promote economic development and the key player of social progress.Along with the increase of automobile pollution and day by day universal, improved greatly people's life, expanded people's radius of action, adapted to the needs of modernization industry, meanwhile, also alleviated the drawback of bringing due to industrialization and urbanization.Yet people, when enjoying automobile civilization, also must face the negative effect that automobile brings: problem of environmental pollution and problem of energy crisis.In this case, zero-emission " and the electronlmobil of " low noise " just arisen at the historic moment.
In the process of moving, front deck dynamic assembly and installation electric component need bear vibration or impact loading to electronlmobil.For the vibration of isolation and decay dynamic assembly, and the impulsive force of decay dynamic assembly, to realize noise reduction object and to improve driver comfort.When structure design, just introduced a novel front cabin skeleton structure.This structure has that intensity is high, rigidity is large, facilitate front deck arrangement of parts, can meet the advantages such as lightweight requirements and processing technology are simple simultaneously.The front cabin skeleton structure that electronlmobil is used at present, because section form is various, therefore processing technology is complicated, needs a large amount of large-scale punching press, machining equipment.And some beam section structures are comparatively simple, as channel-section steel, but its intensity is very poor.If adopt the channel-section steel of large interface in order to increase the intensity of mounting structure merely, increase again large vehicle frame weight and cost.
Summary of the invention
The object of the invention is to: design the novel front cabin skeleton structure of a kind of electronlmobil, being convenient to dynamic assembly and electric component installs and effectively utilizes front deck space, isolation or decay front deck bear vibration and impact loading, effectively improve the strength and stiffness of front cabin skeleton structure.
The technical solution used in the present invention:
The novel front cabin skeleton structure of a kind of electronlmobil, it comprises the left longeron of front deck and front deck right vertical beam, between the left longeron of front deck and front deck right vertical beam, be provided with front deck crossbeam skeleton structure, described front deck crossbeam skeleton structure and the left longeron of front deck, front deck right vertical beam forms a kind of frame type front cabin skeleton structure, described frame type front cabin skeleton structure is divided upper and lower two-layer layout by cabin of electric automobile, its lower floor is provided with a dynamic assembly left side and suspends, the dynamic assembly right side suspends and dynamic assembly rear-suspending, its upper strata is provided with IPU mounting hole and DCDC mounting hole, frame type front cabin skeleton structure top is separately installed with IPU and DCDC by IPU mounting hole and DCDC mounting hole, frame type front cabin skeleton structure bottom is provided with drive motor and retarder, described drive motor and retarder form power assembly of electric automobile by hard connection, described power assembly of electric automobile is by its left mounting bracket, right mounting bracket and rear suspension bracket suspend with a front deck dynamic assembly left side respectively, the dynamic assembly right side suspends and is connected with dynamic assembly rear-suspending.
Above-mentioned front deck crossbeam skeleton structure is two square steel skeleton structures, and its both sides are separately fixed on the left and right longeron of front deck, on two side girders, mounting flange are set, for welding with described square steel skeleton structure.
The technique effect that the present invention obtains:
This cabin of electric automobile skeleton structure can be installed separately the power system of automobile front chamber and all the other annexes, makes the layout of front deck more flexible, keep in repair more convenient, simultaneously this structure have advantages of high strength and rigidity large.Reduce a large amount of connection brackets and brace panel, met the simple requirement of existing automotive light weight technology and processing technology.This automobile body fore-cabin mounting structure can be applicable to widely the front deck parts of various electronlmobils and install.
Cabin of electric automobile skeleton structure comprises the left longeron of front deck, front deck right vertical beam and front deck crossbeam skeleton structure.This front deck crossbeam skeleton structure can be arranged and need to design its mounting bracket according to front deck, be had stronger alerting ability.Front deck is divided into upper and lower double-layer structure, and superstructure is installed DCDC and IPU, and 2 of the left and right that understructure is installed dynamic assembly suspend.Actv. has utilized front deck space.This structure can also be welded with reinforcing bar according to actual needs, plays and improves front deck intensity and the fixedly effect of electrical equipment wiring harness.
Accompanying drawing explanation
Fig. 1 is the novel front cabin skeleton constructional drawing of electronlmobil of the present invention;
Fig. 2 is front deck dynamic assembly of the present invention and front deck mounting parts constructional drawing;
Fig. 3 is the novel front cabin skeleton constructional drawing that battery-driven car dynamic assembly and electric parts are housed.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Referring to Fig. 1-3, the novel front cabin skeleton structure of a kind of electronlmobil, it comprises the left longeron 4 of front deck and front deck right vertical beam 8, between the left longeron of front deck and front deck right vertical beam, be provided with front deck crossbeam skeleton structure 3, described front deck crossbeam skeleton structure and the left longeron of front deck, front deck right vertical beam forms a kind of frame type front cabin skeleton structure, described frame type front cabin skeleton structure is divided upper and lower two-layer layout by cabin of electric automobile, its lower floor is provided with a dynamic assembly left side and suspends 5, the dynamic assembly right side suspends 7 and dynamic assembly rear-suspending 6, its upper strata is provided with IPU mounting hole 1 and DCDC mounting hole 2, frame type front cabin skeleton structure top is separately installed with IPU15 and DCDC9 by IPU mounting hole and DCDC mounting hole, frame type front cabin skeleton structure bottom is provided with drive motor 12 and retarder 11, described drive motor and retarder form power assembly of electric automobile by hard connection, described power assembly of electric automobile is by its left mounting bracket 10, right mounting bracket 13 and rear suspension bracket 14 suspend 5 with a front deck dynamic assembly left side respectively, the dynamic assembly right side suspends and 7 is connected with dynamic assembly rear-suspending 6.Described front deck crossbeam skeleton structure is two square steel skeleton structures, and its both sides are separately fixed on the left and right longeron of front deck, on two side girders, mounting flange are set, for welding with described square steel skeleton structure.
