Abstract

The utility model discloses a motor shroud, the shroud column structure of this motor shroud for dismantling the formula of lifting on, this motor shroud be the motor shroud of an adoption GMT material, and this motor shroud includes a shroud body, a plurality of strengthening rib and a plurality of stiffening rib, and these a little strengthening ribs all set up in the surface of this shroud body, and these a little stiffening ribs all set up in the internal surface of this shroud body. The utility model discloses a novel light weight material replaces traditional steel for motor shroud is the light more, thereby realizes reducing the function of tare. Adopt and lift formula shroud column structure and detachable structural design on new, abdicate for the motor and arrange the space, satisfy and to bear, the demand dismantled at any time.

Description

Motor cover

Technical field

The utility model is related to a kind of motor cover, more particularly to one kind can carry, it is lighter and dismountable Motor cover.

Background technology

With energy-conservation and the requirement of environmental protection, lightweight has become the new trend of world car development.And light-weighted requirement In addition to haveing breakthrough in structure design, new diseases are also importance.In order to drop weight, now many body parts are opened Begin using aluminium alloy, magnesium alloy etc., but the application of composite is relatively fewer.

In existing certain electric motor car, because power assembly is rearmounted, EDU (motor) motor is arranged in base plate lower section after vehicle body Region, after at base plate tyre-well structure traditional sinking pit type can not be adopted to design, as shown in Figure 1.But this realization The material that mode is used not lightweight, is unfavorable for carrying, and existing cover lid is generally individually and vehicle body integral structure, not side Just demolition and maintenance.

Utility model content

A kind of problem and shortage that the utility model exists for prior art, there is provided new motor cover.

The utility model is to solve above-mentioned technical problem by following technical proposals：

The utility model provides a kind of motor cover, and its feature is that the motor cover is the cover lid of detachable, upper lift formula Shape structure, for one, using GMT, (GMT is a kind of prepreg of glass thermoplastic materials to the motor cover, is that glass and thermoplastic are pre- Semi-finished product sheet material made by elder generation) material motor cover, the motor cover include a bonnet body, multiple reinforcements and it is multiple plus Strong rib, those reinforcements may be contained within the outer surface of the bonnet body, and those ribs may be contained within the interior table of the bonnet body Face.

It is preferred that the ribs is triangle ribs.

It is preferred that those reinforcements are seven, wherein four reinforcements are longitudinally laid in the outer surface of the bonnet body, three Root reinforcement is laterally laid in the outer surface of the bonnet body.

It is preferred that the outward flange of the bonnet body is provided with a mounting groove, installation rubber strip is installed in the mounting groove.

It is preferred that being further opened with multiple through holes on the outward flange of the bonnet body, the bonnet body wears this by bolt A little through holes are fixedly connected with vehicle body.

On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, obtain final product the utility model respectively compared with Good example.

Positive effect of the present utility model is：

1st, by novel light material substitution tradition steel so that motor cover is lighter, so as to realize reducing vehicle body weight The function of amount.

2nd, it is that motor concedes arrangement space using new upper lift formula cover lid-like and detachable structure design, Satisfaction can be carried, the demand dismantled at any time.

Description of the drawings

Fig. 1 is the integrated figure of sinking pit type cover lid and part body part in prior art.

Fig. 2 is the schematic diagram one of the motor cover of the utility model preferred embodiment.

Fig. 3 is the schematic diagram two of the motor cover of the utility model preferred embodiment.

Fig. 4 is the motor cover of the utility model preferred embodiment and the integrated figure of part body part.

Specific embodiment

It is new below in conjunction with this practicality to make purpose, technical scheme and the advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, is clearly and completely described, it is clear that retouched to the technical scheme in the utility model embodiment The embodiment stated is a part of embodiment of the utility model, rather than the embodiment of whole.Based on the enforcement in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made all belongs to In the scope of the utility model protection.

As in Figure 2-4, the present embodiment provides a kind of motor cover, the motor cover has can be carried, it is lighter with And dismountable function.

As shown in Fig. 2 the present embodiment is optimized using the traditional iron and steel of new GMT material substitutions to new construction, obtain The cover lid of intensity, durable requirement must be met.First, not uniform thickness design, the most of region of cover lid are carried out according to stress analysis result For 3mm, the position being connected with vehicle body thicker (most thick 6.3mm).

Continue to see Fig. 2 and 4, the motor cover is the cover lid-like of a dismountable, upper lift formula, the motor cover includes The reinforcement 2 and multiple through holes 3 of vertical three horizontal strokes of one bonnet body 1, four, those reinforcements 2 may be contained within the appearance of the bonnet body 1 Face, those through holes 3 are located on the outward flange of the bonnet body 1, and the bonnet body 1 wears those through holes 3 and vehicle body by bolt (see Fig. 4) is fixedly connected, meanwhile, inserts is added near through hole 3.

As shown in figure 3, the motor cover also includes multiple triangle ribs 4 and mounting groove 5, those triangle ribs 4 inner surfaces that may be contained within the bonnet body 1, the mounting groove 5 is arranged at the outward flange of the bonnet body 1, peace in the mounting groove It is provided with installation rubber strip.

Jing model analysis verify that the design of traditional iron and steel panel beating cover lid is limited by moulding process etc., it is difficult to meet intensity, resistance to Require long, merely its thickness thickened to 1.2mm from 1.0mm, though stress value decreases, but still differ greatly with desired value, If continuing to thicken, it is contemplated that the various aspects such as cost and technique, have little significance.After employing new material GMT, according to stress point Cloth result combines the moulding process of GMT materials, and optimization has obtained the new upper lift formula cover structure with deep floor, not only intensity Performance is up to standard, and weight is also reduced to 3.4kg by original 7.4kg.Relatively conventional structure, new material, new construction are not only obviously improved Performance, and weight greatly reduces 4kg.

Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely illustrative of, and protection domain of the present utility model is defined by the appended claims.Those skilled in the art Member can make numerous variations to these embodiments or repair on the premise of without departing substantially from principle of the present utility model and essence Change, but these changes and modification each fall within protection domain of the present utility model.
