In addition, the description for being such as related to " first ", " second " in the present invention is used for description purposes only, and cannot manage Solution is its relative importance of indication or suggestion or the quantity for implicitly indicating indicated technical characteristic.Define as a result, " the One ", the feature of " second " can explicitly or implicitly include at least one of the features.It is " more in the description of the present invention, It is a " it is meant that at least two, such as two, three etc., unless otherwise specifically defined.

In the present invention unless specifically defined or limited otherwise, term " connection ", " fixation " etc. should do broad sense reason Solution, for example, " fixation " may be a fixed connection, may be a detachable connection, or integral；It can be mechanical connection, it can also To be electrical connection；It can be directly connected, the connection inside two elements can also be can be indirectly connected through an intermediary Or the interaction relationship of two elements, unless otherwise restricted clearly.It for the ordinary skill in the art, can be with The concrete meaning of above-mentioned term in the present invention is understood as the case may be.

It in addition, the technical solution between each embodiment of the utility model can be combined with each other, but must be with ability Based on domain those of ordinary skill can be realized, it will be understood that when the combination of technical solution appearance is conflicting or cannot achieve The combination of this technical solution is not present, also not within the protection scope of the requires of the utility model.It should be appreciated that this place is retouched The specific embodiment stated is only used to explain the utility model, is not used to limit the utility model.

As shown in Figures 1 to 6, hood provided by the utility model includes outside plate 1 and inner panel 2, outside plate 1 and inner panel 2 It is plastic part, the one side of outside plate 1 towards inner panel 2 is equipped with welding plate 11, and inner panel 2 offers the through-hole 21 cooperated with welding plate 11. The outside plate 1 and inner panel 2 of the present embodiment are injection molding, have the advantages that molding simply and be easy to make, and with it is traditional Metal plate hood is compared, and since the outside plate 1 and inner panel 2 of the hood are plastic part, largely alleviates hair The quality of motivation cover realizes light-weighted design, meets the loss of weight and power conservation requirement of electric car, and can also improve moulding The freedom degree of design.

After welding plate 11 in the hood on outside plate 1 and the through-hole 21 on inner panel 2 cooperate, using welding process by outside plate 1 and inner panel 2 link together, realize the fixation of outside plate 1 and inner panel 2, and at the same time meet the intensity requirement of hood, guarantee The appearance quality of outside plate 1.The outside plate 1 of the present embodiment hood and the connection type of inner panel 2 are simple and convenient, at low cost, and The intensity requirement of hood can be met simultaneously.

Further, in this embodiment the quantity of welding plate 11 be it is multiple, multiple welding plates 11 along close to outside plate 1 edge between It is consistent with the quantity of welding plate 11 every the quantity of arrangement, through-hole 21 and correspond arrangement, conducive to by the outside plate 1 of hood and interior The multi-faceted fixation of plate 2 is securely attached together outside plate 1 and inner panel 2, and guarantee the marginal position of hood simultaneously Intensity.

In the present embodiment, welding plate 11 is in bar shaped plate, and through-hole 21 is in strip-shaped hole, has structure simply and is easy to make excellent Point.Interval in view of the shrinkage of plastic material product, between the edge of the outside plate 1 of the present embodiment and the edge of inner panel 2 For 3mm-5mm, it is convenient for assembly outside plate 1 and inner panel 2.

As shown in figures 1 and 3, in order to guarantee the intensity of hood entirety, in the present embodiment, outside plate 1 and inner panel 2 Intermediate region is connected using bolt 3, specifically, bolt block is provided on outside plate 1, and inner panel 2 is equipped with the hole passed through for bolt block, Bolt 3 cooperates with bolt block outside plate 1 and inner panel 2 to be connect.Since the open angle of hood is limited, and its wedge angle 10 The case where stress set compares concentration, and 10 position of wedge angle is caused to be easy to appear deformation and the fracture of welding plate 11, in order to avoid becoming The case where shape and welding plate 11 are broken, 10 position of wedge angle of outside plate 1 and 10 position of wedge angle of inner panel 2 are using double groups in the present embodiment Divide polyurethane adhesive bonding, before bonding, using the surface of 10 position of wedge angle of plasma treatment outside plate 1 and the wedge angle 10 of inner panel 2 Surface of position, to improve the surface energy of the surface energy of 10 position of wedge angle of outside plate 1 and 10 position of wedge angle of inner panel 2, to be conducive to Bonding.Meanwhile two component polyurethane glue sticking, the present embodiment hair are integrally used compared to the hood of existing plastic material Motivation cover only uses two component polyurethane glue sticking in 10 position of wedge angle, is conducive to reduce input cost.

In the present embodiment, outside plate 1 is made of ethylene propylene diene rubber blended and modified polypropylene (PP+EPDM-T30) material, interior Plate 2 is made of long glass fiber-reinforced polypropylene (PP+LGF40) material, and PP is substrate, excellent with low manufacture cost with being easy to make Point.Further, outside plate 1 with a thickness of 2.5mm-3.5mm, preferably 3mm, inner panel 2 with a thickness of 3mm-3.5mm, preferably 3mm, compared with identical with area and traditional metal plate hood with a thickness of 0.65mm, the quality of the hood of the present embodiment The quality of the opposite metal plate hood alleviates 34%, realizes the light-weighted design of hood.In the present embodiment, outside plate 1 It is integrally formed design with inner panel 2, has the advantages that be easy to make and low manufacture cost.

Further, in this embodiment the outer surface of outside plate 1 can make multiple small tag type faces, i.e., formed on outside plate 1 There are multiple curved surfaces, obtain preferable presentation quality and realize the shape-designing of multiplicity, and due to 1 He of the outside plate of the hood Inner panel 2 is plastic part, the angle of the two sides wedge angle 10 of hood can be designed as 40 ° -60 °, is reduced to starting The limitation of the shape-designing of hood improves the freedom degree of shape-designing.

In addition, the utility model also provides a kind of electric car, which includes vehicle body main body and such as above-mentioned hair Motivation cover, hood are mounted in vehicle body main body.Since the vehicle uses whole technical solutions of above-mentioned all embodiments, Therefore at least there are all beneficial effects brought by the technical solution of above-described embodiment, this is no longer going to repeat them.

The above is only the preferred embodiments of the utility model, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
