Description

Technical Field

[0001] This utility model relates to the field of spring arm packaging technology, and in particular to a packaging box for automotive suspension spring arms. Background Technology

[0002] The spring arm is an important component of the rear suspension of a car chassis. Its outer end connects to the steering knuckle, its inner side connects to the subframe, and its middle section connects to components such as the shock absorber, shock absorber spring, and stabilizer bar connecting rod. It provides the following required functions: 1. Transmitting suspension load; 2. Supporting the spring, stabilizer bar connecting rod, and shock absorber; 3. Meeting the requirements of geometry and elastic kinematics.

[0003] Due to the complex stress conditions of the spring arm and the highly irregular structure of the parts, the packaging uses a flat-laying method. During transportation, the products are prone to sliding and bumping during sudden braking, sharp turns, and driving over potholes. Furthermore, the multi-layered flat-laying arrangement means that after each layer of products is used, workers must remove the dividers and pads from that layer and stack them in a designated location. After the entire box of products is used, all dividers and pads must be returned to the crate for recycling, which is very inconvenient. Therefore, reducing parts collisions and minimizing the number of steps required for workers in vehicle assembly plants are urgent problems to be solved in mass production. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a car suspension spring arm packaging box, in which one spring arm is placed in each small compartment, and a plug is inserted into the bushing at the upper part of the spring arm.
