Description

Technical Field

The control box cover in the onboard touch control screen is a key component. Therefore, the control box cover plays a vital role in the onboard touch control screen. Figure 4 and 5 The figure shows the control box cover 49 in the vehicle-mounted touch control screen. The surface of the control box cover 49 is printed with arrows 49-1 and engraved lines 49-2 to facilitate assembly, and the control box cover 49 has downward flanges 49-3 on all sides to facilitate assembly. In addition, with the rapid development of new energy vehicles, production is increasing, and the demand for control box covers is increasing. In order to meet the production needs of customers, it is necessary to improve the utilization rate of product raw materials and improve the production efficiency of products to meet the production needs of customers.

[0003] At present, the control box cover products in the on-board touch control screen of new energy vehicles are mainly produced by continuous molds, and step-by-step stamping production is carried out by adding material points in the width direction of the shape.
