Description

TECHNICAL FIELD

[0001] The present application relates to a pickup truck cargo box side wall structure assembly, which is applied to a light commercial vehicle (pickup truck) and belongs to the technical field of automobile bodies. BACKGROUND

[0002] According to market demand, cargo boxes of different widths are provided for selection. Due to the different overall structures of the cargo boxes, the development cycle of the cargo boxes is relatively long, and the development cost is relatively high. Since the wheel cover bending part of the cargo box side wall outer plate is an open structure, the springback amount of the stamping part is difficult to control. In order to ensure the stamping forming, a relatively large springback angle is often set, and the splash guard is often fixed in a whole lap joint form. The side view edge of the splash guard and other exterior trim parts is obviously exposed, which seriously affects the appearance quality of the cargo box. With the increase of living standards, higher demands are put forward for pickup trucks. The single carrying function cannot meet the needs of users. At present, the charging seat of the pickup truck cargo box is mostly a ready-made product fixed on the cargo box by modification. The inner plate product of the cargo box is a large-size thin plate stamping part. It is difficult to preinstall a raised nut, and the installation strength of the charging seat is weak. In addition, the charging seat is convex, which affects the carrying, loading and unloading of goods and the safety of electrical appliances. When the "L" type bracket is welded to the upper part of the inner and outer plates, the welding point position cannot be visually confirmed due to the influence of the bending structure. It is necessary to manually mark in advance or increase the investment in automatic equipment, which is low in production efficiency and high in production cost. The traditional tail lamp mounting point is arranged on the cargo box outer plate and the connecting part thereof. The precision requirement of the tail lamp matching surface at the rear part of the cargo box outer plate is high, and the stability is poor. However, a large installation force is required for the tail lamp assembly, which is easy to cause the deformation of the matching surface at the tail lamp port, thereby affecting the appearance.
