In above-mentioned fuel tank welding support, described installing hole one is opened in the middle part of groove one, and center of circle installing hole one center of circle of described installing hole two is not at same perpendicular.
The design of the position of installing hole one and installing hole two improves the intensity of installation position so that fuel tank, methanol canister and seat are convenient, be firmly installed on rack body, improve installation effectiveness.
In above-mentioned fuel tank welding support, the thickness of described rack body is 20mm～30mm.
Being arranged within the scope of this by the thickness of rack body, rack body when ensureing to meet intensity, can improve the light-weight design of vehicle body, better realize the punch forming of rack body simultaneously to greatest extent.
Compared with prior art, this fuel tank welding support has the advantage that
1, the setting of groove one and protruding cavity, adds the integration of rack body, also mitigates the weight of other supports needed in the art simultaneously, it is achieved that the light-weight design of rack body.
2, being equipped with of groove one, groove two, flange one, flange two and protruding cavity, the cross section of rack body can be made substantially in undaform, improving the intensity of support, when car load is reversed, the bending stiffness of rack body also has lifting, can better realize the light-weight design of rack body.
3, the thickness of rack body is arranged so that rack body when ensureing to meet intensity, can improve the light-weight design of vehicle body, better realize the punch forming of rack body simultaneously to greatest extent.
