Description

New energy logistics vehicles and carriages

technical field

The utility model relates to the technical field of vans and new energy vehicles, in particular to a new energy logistics vehicle and a carriage.

Background technique

Vans, also known as vans, are mainly used for fully sealed transportation of various items, and special types of vans can also transport chemical dangerous goods. In the transportation process, the van has the advantages of flexible maneuverability, convenient operation, efficient work, large transportation volume, full use of space, safety and reliability. Traditional vans are fuel vehicles, with sufficient power, long mileage and easy refueling. Therefore, iron corrugated boards are generally used to make the carriages. Such carriages are heavier, which will lead to short cruising range of new energy vehicles and cannot meet the requirements of new energy vehicles. The blue card is required to be listed, that is, it cannot be used on electric new energy vehicles. Moreover, at present, cities around the world have higher and higher requirements for energy conservation and environmental protection, and the express logistics industry also needs more new energy logistics vehicles to meet their needs.

The Chinese patent document with publication number CN106394706A discloses a logistics vehicle and its compartment, including a compartment body, and the compartment body includes a compartment panel assembly, an underframe assembly, a skirt assembly and a rear door panel assembly. Above the chassis assembly, the skirt assembly is arranged below the chassis assembly, and the rear door panel assembly is simultaneously connected with the car panel assembly, the chassis assembly and the skirt assembly; the logistics vehicle includes the above-mentioned compartment. The utility model has the advantages of simple structure, low self-weight and easy assembly, so that the carriage can be used on new energy vehicles, but the new energy logistics carriage has the following technical defects:

1) The side panel of the carriage and the chassis are connected by connecting bars arranged on the outside of the carriage, the connection strength is low, the structure is not firm enough, and the connecting bar connecting the side with the side door and the chassis is divided into three sections, Affects the overall structural strength of the carriage and the connection strength of the side door frame components to the side panels and chassis of the carriage;

2) The underframe of the carriage is welded into a whole by I-beam, which is large in size and heavy in weight. It is very inconvenient to transport, store and install, and for carriages of different sizes and specifications, it needs to be customized by the underframe manufacturer. Assembly plants are difficult and inefficient to assemble themselves;

3) When the car roof is installed, the left edge, front edge and rear edge of the roof are first fixed with the three first connectors, and then the roof is installed on the side plate of the car by the crane, which requires three first connections. The first connecting grooves on the parts must be fastened to the side panels of the carriage at the same time, but since the installation is located inside the carriage, there is no positioning aid, which makes it necessary to keep trying to connect the first connecting grooves on the three first connecting parts at the same time. It is time-consuming and labor-intensive to buckle on the side panel of the carriage, and the above situation is still an ideal installation condition. In the actual installation situation, considering the manufacturing accuracy and matching accuracy, different parts of the first connecting groove and the side panel of the carriage are different. The margins between the parts will change constantly, so that some of the first connecting grooves cannot be fastened to the side panels due to the small margins, and some of the first connecting grooves will affect the stability of the installation of the roof panel due to the large margins;

4) The weight of the carriage is still more than 600kg.

Therefore, patent documents with publication numbers of CN109515520B, CN209600620U, CN209600232U, CN109533026A, CN109515532A, etc. are aimed at the above technical problems 1), 2) and 4), by designing a series of connecting profiles to remove redundant connecting structures, thereby reducing the assembly of the above-mentioned carriages Difficulty, increase the structural strength of the above-mentioned carriage, improve the structure of the carriage underframe; and finally reduce the weight of the carriage to about 525kg while ensuring the structural strength of the carriage.

However, those skilled in the art have found through research that there is still room for further improvement in the structure and weight of the new energy logistics carriages in the patent documents with publication numbers such as CN109515520B, CN209600620U, CN209600232U, CN109533026A, CN109515532A, and the above-mentioned technical problems are not solved. 3).
