Therefore, be necessary to provide a kind of new electric transporting vehicle to solve the problems of the technologies described above in fact.
[utility model content]
The technical matters that the utility model need solve is the deficiency that overcomes technical background, provides a kind of complete vehicle weight light, the electric transporting vehicle that energy consumption is low.
A kind of electric transporting vehicle, comprise aluminium vehicle frame, described aluminium vehicle frame comprises the left longeron assembly that is oppositely arranged and right vertical beam assembly and is connected the crossbeam of described left longeron assembly and described right vertical beam assembly, described left longeron assembly and right vertical beam assembly are symmetrical structure, it is characterized in that, described left longeron assembly comprises upper left longeron and the bottom left longeron overlapping at above-below direction with described upper left longeron, and described upper left longeron and bottom left longeron are prismatic I-shaped aluminium section bar; The side of described upper left longeron and bottom left longeron lap-joint becomes circular-arc by side direction roll bending technique roll bending, and described crossbeam comprises and lays respectively at described left longeron assembly and the front end of described right vertical beam assembly, the front cross rail of rear end, after cross member and some center members and battery box between described front cross rail and after cross member.
Preferably, the side of described left longeron assembly and right vertical beam assembly is fixedly installed reinforcement attached plate.
Preferably, described front cross rail, after cross member are C type beam, and described center member is open circles tubulose beam.
Compare with correlation technique, a kind of electric transporting vehicle chassis side rail of the utility model adopts twin I-beam section bar roll bending package assembly to meet the installation requirements such as the crossbeam operator's compartment discrepancy in elevation, front-rear axle wheelbase.Rationally utilize Battery case structure, reduce crossbeam number.On longeron, establish reinforcement attached plate, improve frame strength, integral structure mainly adopts aluminium alloy structure, and weight is light compared with conventional steel vehicle frame, be particularly suitable for battery-driven car this for the responsive especially vehicle of weight, can under the condition of same charge power, realize longer course continuation mileage.

Fig. 4 is the schematic top plan view of Fig. 3.
In figure: left longeron assembly 1, right vertical beam assembly 2, lap-joint 11, strengthens attached plate 12, upper left longeron 13, bottom left longeron 14, front cross rail 31, after cross member 32, center member 33, battery box 34.
[specific embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As Figure 1-4, a kind of electric transporting vehicle, comprises aluminium vehicle frame, and aluminium vehicle frame comprises the left longeron assembly 1 that is oppositely arranged and right vertical beam assembly 2 and is connected the crossbeam of left longeron assembly 1 and right vertical beam assembly 2.Left longeron assembly 1 and right vertical beam assembly 2 are symmetrical structure.Wherein, left longeron assembly 1 comprises upper left longeron 13 and the bottom left longeron 14 overlapping at above-below direction with upper left longeron 13, and upper left longeron 13 and bottom left longeron 14 are prismatic I-shaped aluminium section bar; The side of the lap-joint 11 of upper left longeron 13 and bottom left longeron 14 becomes circular-arc by side direction roll bending technique roll bending, and crossbeam comprises and lays respectively at left longeron assembly 1 and the front end of right vertical beam assembly 2, the front cross rail of rear end 31, after cross member 32 and the center member 33 between front cross rail 31 and after cross member 32 and battery box 34.Because the intensity of aluminium section bar is lower than steel, with the steel ratio of same structure, aluminium section bar is carried out to side direction roll bending and be more prone to realize.Chassis side rail adopts twin I-beam section bar roll bending package assembly to meet the installation requirements such as the crossbeam operator's compartment discrepancy in elevation, front-rear axle wheelbase.Article two, the I-beam section of overlap joint adopts and is threaded, and is convenient to processing and assembling.Rationally utilize battery box 34 body structures, by battery box 34 be arranged at left longeron assembly 1 and right vertical beam assembly 2 between, played the effect of middle beam, reduced crossbeam number.
The side of left longeron assembly 1 and right vertical beam assembly 2 is fixedly installed strengthens attached plate 12.According to the loading characteristic of electric transporting vehicle each several part, select corresponding version.And for some weakness, carried out various forms of attached plates and strengthened, thereby guaranteed under less materials'use, the intensity of vehicle frame, rigidity have all reached the requirement of using, and each several part is stressed evenly, intensity surplus is less, and unitized frame weight is compared conventional steel vehicle frame and greatly reduced.Be particularly suitable for battery-driven car this for the responsive especially vehicle of weight, can under the condition of same charge power, realize longer course continuation mileage.
Front cross rail 31, after cross member 32 are C type beam, and center member 33 is open circles tubulose beam.C type beam is conducive to form good framework architecture, is also convenient to and other Member Weldings simultaneously.Center member 33 only two ends need to be welded on left-right longeron, selects open circles tubulose structure welding convenient, and load is even.
Compare with correlation technique, a kind of electric transporting vehicle chassis side rail of the utility model adopts twin I-beam section bar roll bending package assembly to meet the installation requirements such as the crossbeam operator's compartment discrepancy in elevation, front-rear axle wheelbase.Rationally utilize Battery case structure, reduce crossbeam number.On longeron, establish reinforcement attached plate, improve frame strength, integral structure mainly adopts aluminium alloy structure, and weight is light compared with conventional steel vehicle frame, be particularly suitable for battery-driven car this for the responsive especially vehicle of weight, can under the condition of same charge power, realize longer course continuation mileage.
Above-described is only embodiment of the present utility model; at this, it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make improvement, but these all belong to protection domain of the present utility model.
