Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics, especially to a vehicle and a vehicle compartment and a chassis thereof. BACKGROUND

[0002] The vehicle compartment is an indispensable part of modern logistics, and can load a variety of items for transportation at one time through its large capacity, thereby improving the efficiency of each transportation. The vehicle compartment is usually composed of a top plate, side plates, a front plate, and a rear door, and is integrally installed on the chassis of the vehicle.

[0003] According to different vehicle models and purposes, the chassis structures of vehicles are different, and the distances between the longitudinal beams of different vehicle chassis have great differences. Therefore, in order to match different vehicle chassis, customers often need to purchase vehicle compartments with different chassis sizes or re-drill holes in the cross beams and longitudinal beams of the existing vehicle compartment chassis, thereby causing the following problems: 1. When customers use different vehicle chassis, they need to customize new vehicle compartments from the manufacturer, which has a long order cycle and high cost. In order to shorten the order cycle, many customers will purchase different sizes of cargo boxes to stock up, which requires a large storage space and high storage cost; 2. When re-drilling holes in the existing vehicle compartment chassis, the re-drilling process is complicated, and when the positions of the cross beams and longitudinal beams are adjusted slightly, the two holes may coincide, resulting in the chassis being scrapped, and the strength of the re-drilled vehicle compartment chassis is reduced.

[0004] The patent application with the publication number CN112124428A discloses a chassis of an all-aluminum vehicle compartment, which includes a bottom frame, a bottom cross beam, and a secondary longitudinal beam. The bottom cross beam and the secondary longitudinal beam are connected in a cross manner, and the secondary longitudinal beam is connected to the vehicle body beam. The secondary longitudinal beam is configured as a slot structure with a horizontal opening. The bottom cross beam and the secondary longitudinal beam are connected by a cross beam double support, the vehicle head and tail bottom frame and the secondary longitudinal beam are connected by a single support, the support block is supported at the connection node of the secondary longitudinal beam, and the connection is achieved by simple bolts. The installation process is simplified, and the carrying capacity is strong. However, the chassis has the following problems: 1. The cross beam double support is used to support the bottom cross beam, and although the secondary longitudinal beam can move left and right along the bottom cross beam to adjust the distance between the secondary longitudinal beams, the cross beam double support is fixedly connected to the bottom cross beam by bolts after the distance between the secondary longitudinal beams is adjusted, which requires a high drilling position on the bottom cross beam and cannot be reused on different vehicle chassis; 2. The chassis has many connection fittings, such as the cross beam double support, which has a complex structure and requires high structural precision. Moreover, the number of fittings is large, and the fittings are easy to be missed or lost during packaging, long-distance transportation, and installation; 3. The connection structure between the secondary longitudinal beam and the bottom cross beam is exposed, and the overall appearance has poor aesthetic quality. SUMMARY
