The utility model discloses sub vehicle frame before lightweight electric automobile's quality is light, and structural strength is high.
Description
Technical field
The utility model relates to electronlmobil field, particularly relates to a kind of light-weight electric automobile fore sub frame.
Background technology
Subframe can regard the skeleton of tandem axle as, is the component part of tandem axle.Subframe incomplete vehicle frame, just supported the support of tandem axle, suspension, make vehicle bridge, hang and be connected with " positive vehicle frame " by it again, be called traditionally " subframe ".The effect of subframe also comprises obstruct vibration & noise, reduces it and directly enters compartment.
For the automobile that complete vehicle quality is higher, particularly as the electronlmobil that course continuation mileage is long, by power brick weight, carload is higher, and as the carrying core of chassis front suspension, the requirement of strength of fore sub frame is often higher.For meeting the requirement of strength of these parts, select thicker sheet material to solve normally by double layered main body, but because of fore sub frame assembly accessory size specification comparatively large, carry out sheet material thickening, often cause that pts wt increases, manufacturing cost improves.The subframe of traditional design, material thickness be 3.0mm even more than.Thus the material thickness that there is fore sub frame is large, assembly pts wt is large, is unfavorable for that car load lightweight realizes, and fuel economy is poor and raw materials consumption is large, the problems such as manufacturing cost is higher.
Utility model content
The technical problems to be solved in the utility model, for solving the problems of the technologies described above, the utility model provides a kind of quality lighter, can ensure again enough structural strengths, light-weight electric automobile fore sub frame simultaneously.
The utility model is achieved in that
A kind of light-weight electric automobile fore sub frame, comprises, fore sub frame main body, left brace panel and right brace panel;
Described fore sub frame main body is shaping by monolithic steel plate punched, and the left and right sides of fore sub frame main body to be provided with before lower swing arm point of connection after point of connection and lower swing arm;
Described left brace panel and right brace panel are by the strip brace panel of steel plate punched, left brace panel to be welded in before the lower swing arm on the left of fore sub frame main body after point of connection and lower swing arm between point of connection, and right brace panel to be welded in before the lower swing arm on the right side of fore sub frame main body after point of connection and lower swing arm between point of connection.
Further, the left and right sides of described fore sub frame main body is arranged at horizontal strengthening groove respectively, and described left brace panel and right brace panel are arranged at the longitudinal strengthening groove orthogonal with described horizontal strengthening groove respectively.
Further, the thickness of the left brace panel of described fore sub frame main body and right brace panel is 1.5mm.
Further, the edge of described left brace panel and right brace panel is provided with flange, and left brace panel and right brace panel are welded with fore sub frame main body by described flange.
The utility model tool has the following advantages: be different from existing fore sub frame and adopt doubling plate to be welded, the main body of the utility model light-weight electric automobile fore sub frame is shaping by monolithic steel plate punched, and adopt the main stress point of (simplification) brace panel to major-minor bicycle frame both sides of two strips to carry out intensity reinforcement, thus alleviate the quality of fore sub frame, in turn ensure that the structural strength of fore sub frame simultaneously.

Detailed description of the invention
By describing technology contents of the present utility model, structural attitude in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Refer to Fig. 1 and Fig. 2, the utility model embodiment, a kind of light-weight electric automobile fore sub frame, this light-weight electric automobile fore sub frame comprises, fore sub frame main body 1, left brace panel 2 and right brace panel 3.
Described fore sub frame main body 1 is shaping by monolithic steel plate punched, and the left and right sides of fore sub frame main body 1 to be provided with before lower swing arm point of connection 12 after point of connection 11 and lower swing arm.The left and right two of described fore sub frame is connected front lower swing arm 4 respectively by point of connection 12 after point of connection 11 before described lower swing arm and lower swing arm.
Described left brace panel 2 and right brace panel 3 are by the strip brace panel of steel plate punched, left brace panel 2 to be welded in before the lower swing arm on the left of fore sub frame main body 1 after point of connection 11 and lower swing arm between point of connection 12, and right brace panel to be welded in before the lower swing arm on the right side of fore sub frame 1 after point of connection 11 and lower swing arm between point of connection 12.
The utility model embodiment light-weight electric automobile fore sub frame eliminates the structure of the double layered main body of existing subframe, this fore sub frame main body is single layer structure, and after point of connection 11 and lower swing arm, between point of connection 12, brace panel is set before 2 main stress point lower swing arms of fore sub frame main body, thus reach the object of expendable weight, in turn ensure that the structural strength of fore sub frame simultaneously.
Further, in the present embodiment, the left and right sides of described fore sub frame main body 1 is arranged at horizontal strengthening groove 13 respectively, and described left brace panel 2 and right brace panel 3 are arranged at the longitudinal strengthening groove 21,31 orthogonal with described horizontal strengthening groove 13 respectively.
Described horizontal strengthening groove 13 and longitudinal strengthening groove 21 and 31 are omnidirectional distribution in the present embodiment, thus improve the warping resistance intensity of fore sub frame each side.
Further, in the present embodiment, the left brace panel of described fore sub frame main body 12 and right brace panel 3 are thickness is that the steel plate punched of 1.5mm forms.Further, the edge of described left brace panel 2 and right brace panel 3 is provided with flange, and left brace panel and right brace panel are welded with fore sub frame main body by described flange.With the fore sub frame of existing double layered main body structure, before the utility model, the total quality of secondary vehicle reduces 6kg, and controlled at 14kg, expendable weight is about 27.5% of total mass, and part raw materials consumption single-piece reduces 50%.Simultaneously due on described left brace panel 2 and right brace panel 3 all by flanging welded in fore sub frame main body 1, make to form the cavity that a cross section is arch between the left brace panel of fore sub frame main body 12 and right brace panel 3, thus improve the warping resistance intensity of fore sub frame, can bear to lower swing arm pass to come stronger impact.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification sheets and accompanying drawing content to do equivalent shapes or Structural Transformation; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
