Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of for backplate under the battery pack of pure electric automobile, comprising: the first plate 1, second plate 2 and the 3rd plate 3.Wherein, the first plate 1 and the 3rd plate 3 are rectangle, and the second plate 2 is in square, and the second plate 2 is vertically set in the middle part of the side broadside of the first plate 1, and the first plate 1 and the second plate 2 are formed in one structure, overall in T-shape after the first plate 1 and the second plate 2 are connected.The width of the 3rd plate 3 is identical with the width of the first plate 1, and the side broadside of the 3rd plate 3 overlaps with the broadside relative with the second plate 2 on the first plate 1.First plate 1, second plate 2 and the 3rd plate 3 are that the composite material of PP and PE is made, this material possess heat-resisting, resist cold, cold and heat succeed each other and shock resistance.To be followed closely by bolt, nut and spring cotter in lap-joint on the lower house and car load subframe that this backplate is fixed on battery pack, after the below of battery pack installs this lower backplate additional, can effectively avoid sandstone to the impact of battery pack, strengthen the protection to battery pack, and then also improve the safety of car load.
It is overall in T-shape after first plate 1 and the second plate 2 are connected, the bottom of the second plate 2 is ramp shaped flow-guiding type structure, as shown in Figure 2, when the front end of air from the second plate 2 flows into, when flowing to the first plate 1 and the 3rd plate 3, air can flow to the bottom of the first plate 1 and the second plate 2 naturally along moulding surface structure, this design effectively reduces the windage that car load is subject in the process of moving, simultaneously the first plate 1 and the second plate 2 have employed the assembling mode overlapped up and down, and which effectively overcomes whole lower guard plate apparatus can produce at car load driving process the deficiency that wind makes an uproar.
First plate 1, second plate 2 and the 3rd plate 3 are provided with air channel, cooling effect can be played to battery pack.
As shown in Figure 3 and Figure 5, in order to make the connection of the lower house of lower backplate and battery pack and car load subframe fastening, preferably, the first plate 1 and the second plate 2 are evenly distributed with on the first mounting hole the 4, three plate 3 are evenly distributed with the second mounting hole 5.By the first mounting hole 4 and the second mounting hole 5, by bolt can by lower backplate and the lower house of battery pack and the connection of car load subframe more fastening.Because two shoulder structures of the junction of the first plate 1 and the second plate 2 are thiner, for this reason, further preferably, the first mounting hole 4 is provided with at two shoulders, be fastenedly connected by the lower house of bolt and battery pack and car load subframe, avoid the first plate 1 and the second plate 2 ruptures in junction.
A kind of embodiment, as shown in Figures 3 to 6, the first plate 1 is evenly distributed with on the second guiding gutter 8 and the first leaking hole 7, second plate 2 and is evenly distributed with the first guiding gutter 6.3rd plate 3 is evenly distributed with the second guiding gutter 8 and the second leaking hole 9.First leaking hole 7 and the second leaking hole 9 are all arranged on the nadir of profile, the design of leaking hole avoids battery pack lower house and can produce ponding, when backplate under power has ponding, water can flow out by the rounding off curved surface in the first guiding gutter 6 and the second guiding gutter 8, flows away from leaking hole.
Consider the strength problem of lower backplate, as shown in Figure 3 and Figure 5, the first plate 1 and the second plate 2 all arrange the first reinforced rib 10, this first reinforced rib 10 is uniformly distributed in the profile of the first plate 1 and the second plate 2.3rd plate 3 is evenly distributed with the second reinforced rib 11, in addition, the long limit, both sides of the 3rd plate 3 is provided with flange, and reinforced rib and flange ensure that lower backplate intensity on the whole.
As shown in Figure 7, under battery pack, backplate all has the structure design of external flanging type obliquely, and whole battery pack wraps by this design dexterously, can play sufficient protective action to battery pack.Under battery pack backplate profile on all have arrow points to identify, this mark can allow assembly crewman be easy to just pick out assembly direction, reaches mistake proofing object.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, and these embodiments are all included within scope of the present utility model.
