Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.The experimental technique of unreceipted actual conditions in the following example, the usually conveniently conditioned disjunction condition of advising according to manufacturer.
Unless otherwise defined, all specialties used in literary composition and scientific words and one skilled in the art the meaning be familiar with identical.In addition, any method similar or impartial to described content and material all can be applicable in the utility model method.The use that better implementation method described in literary composition and material only present a demonstration.
Power brick bottom bracket
As shown in Figure 1, power brick bottom bracket of the present utility model, formed by extruded aluminium section 1 welding, inside has cavity.
Aluminium section bar be exactly aluminium bar by hot melt, extruding, thus obtains the aluminum of different cross section shape.Extruding is the means that section bar is shaped, first according to product forms Section Design, produce mould, utilize round casting rod extrusion molding from mould that extruder will heat.Extruded aluminium section of the present utility model, inside is hollow structure.
In another preference, weld with agitating friction again after adopting automatic jig first to carry out extruded aluminium section splicing, obtain described power brick bottom bracket.
In a preferred embodiment, the weight of described power brick bottom bracket is 8-10kg.
In a preferred embodiment, the volume of described power brick bottom bracket is 0.001-0.005m
3.
In a preferred embodiment, the area of described power brick bottom bracket is 2.2-2.8m
2.
In a preferred embodiment, described aluminium section bar inside is provided with reinforcement.
In the utility model, the layout of reinforcement is relevant with required bottom bracket intensity, can need employing means according to required bottom bracket intensity, as CAE simulation designs.
Bottom bracket of the present utility model, adopt extruded aluminum to carry out welding to form, concentrate the shaping advantage of aluminium two dimension end face, adopt hollow material effectively can stop the heat trnasfer of car halted state, also can utilize the adjustment of the reinforcement width of hollow material simultaneously, carry out the design of pilot hole, at the assembled good rear overall processing of welding, its dimensional uniformity is high, owing to adopting hollow material design, by the structural mechanics of end face designing material and the mechanical structure of material own, the bottom bracket of its aluminium section bar only has about 8-10KG.Be about the half of the weight of steel supporting plate, cost is but consistent with firm cost, and as considered to reclaim, its integrated cost is low compared with steel.
