Abstract
The utility model relates to a rear lower arm structure of a new energy automobile, which comprises a rear lower arm body and a spring tray, wherein a groove is formed in the middle of the rear lower arm body, the groove is matched with the spring tray, and the spring tray is fixedly connected with the rear lower arm body through welding. The utility model has the beneficial effects that: the structure of the spring tray is formed by welding the rear lower arm body and the spring tray, the welding process is simple, the welding process is less, the size of the product is more stable, and the matching part of the rear lower arm and the spring tray adopts a boss structure with a groove, so that the spring tray can more effectively play roles of positioning and preventing rotation compared with the previous circular boss structure, and the flanging structure is added, so that the strength and the durability of the product are better.
Description
Technical Field
The utility model relates to an automobile part structure, in particular to a rear lower arm structure of a new energy automobile.
Background
The rear lower arm used in the existing market is formed by welding a plurality of parts, the number of the parts is 3-4, the size of a finished product of a product is not easy to control, the manufacturing process is complex, a circular boss and a spring disc are arranged at the bottom of the rear lower arm for positioning, but the positioning structure only plays a limiting role, the rotation prevention function is not achieved, and the product structure is not perfect.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provides the rear lower arm structure of the new energy automobile, which is more reasonable in structure and better in performance.
The utility model adopts the technical scheme for solving the technical problems that: this kind of arm structure under new energy automobile back, including back underarm body and spring tray, open slottedly in the middle of the back underarm body, groove and spring tray phase-match, spring tray is fixed through welding and this body coupling of back underarm.
The middle of the spring tray is provided with a boss, and the edge of the boss is provided with a groove.
And the spring tray is provided with a positioning hole.
The two side edges of the rear lower arm body are provided with outward flanges.
The utility model has the beneficial effects that: the structure of the spring tray is formed by welding the rear lower arm body and the spring tray, the welding process is simple, the welding process is less, the size of the product is more stable, and the matching part of the rear lower arm and the spring tray adopts a boss structure with a groove, so that the spring tray can more effectively play roles of positioning and preventing rotation compared with the previous circular boss structure, and the flanging structure is added, so that the strength and the durability of the product are better.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic diagram of a spring tray configuration;
fig. 3 is a schematic structural view of the rear lower arm body.
Description of reference numerals: rear lower arm body 1, spring tray 2, groove 11, turn-ups 12, recess 21, locating hole 22, boss 23.
Detailed Description
The utility model will be further described with reference to the accompanying drawings in which:
as shown in the figure, this kind of arm structure under new energy automobile back, including back underarm body 1 and spring tray 2, open slotted 11 in the middle of back underarm body 1, slotted 11 and spring tray 2 phase-match, spring tray 2 is connected fixedly through welding and back underarm body 1, and welding process is simpler, and the process has reduced, and the size of product is more stable. Spring tray 2 is independent stamping workpiece, is equipped with boss 23 in the middle of spring tray 2, and boss 23 is circular, and the edge of boss 23 is equipped with recess 21, and recess 21 is the convex of indent, plays the effect of location and preventing the spring rotation simultaneously. The spring tray 2 is provided with a positioning hole 22, and the positioning hole 22 plays a role in positioning the spring tray 2 during welding. Two side edges of the rear lower arm body 1 are provided with outward flanges 12, so that the strength and the fatigue resistance of the product are improved.
The structure of the utility model has simple process and low production cost; the product performance is excellent, and the consistency is better; the whole vehicle is well matched, and the effects of bearing the spring disc and preventing the spring from rotating are effectively achieved.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
