Description

Technical Field

[0001] The utility model relates to the field of new energy refrigerated transport vehicles, and particularly to an automatic electrical connection device for the upper body and chassis of a new energy commercial vehicle. Background Technique

[0002] With the continuous growth of the demand in the cold chain logistics market in China, the cold chain transportation industry has developed rapidly, and the technology of new energy refrigerated trucks has also developed rapidly. Manufacturers of various cold chain logistics products have continuously developed chillers with higher efficiency and refrigerated boxes with better heat preservation effects, and designed different chiller devices and cold compartments for different vehicle manufacturers and different vehicle models to meet the unique matching requirements of different vehicle manufacturers and various vehicle models.

[0003] In the existing refrigerated trucks, the chiller is installed and fixed on the cold compartment to form an integral body, and then the integral body of the chiller and the cold compartment is installed and fixed on the vehicle chassis. Most of the chillers of new energy refrigerated trucks are powered by high voltage, and the power supply mostly comes from the power battery of the vehicle. At the same time, the integral body of the chiller and the cold compartment also needs to obtain a low-voltage power supply from the vehicle chassis and conduct CAN communication with the whole vehicle. An operation panel also needs to be set in the cab for the chiller, and some temperature sensors also need to be arranged in the refrigerated box, which are connected to the monitoring equipment on the chassis to collect the temperature information in the refrigerated compartment in real time and send it to the cloud platform of the operator through remote communication equipment. Therefore, there are many power supply and communication interfaces between the integral body of the chiller and the cold compartment and the vehicle chassis.

[0004] Since the chassis designed by each vehicle manufacturer is different, and even the chassis of different vehicle models designed by the same vehicle manufacturer also have differences, when the integral body of the chiller and the cold compartment is connected and matched with each vehicle model, special electrical interface designs need to be carried out to meet the matching requirements of different vehicle models.

[0005] At the same time, during the use of refrigerated trucks, there is usually a scenario where the integral body of the chiller and the cold compartment is separated from the chassis. However, after the traditional integral body of the chiller and the cold compartment is fixed to the vehicle chassis, it cannot be separated during subsequent use, resulting in a lack of convenience in actual use. Therefore, technical personnel in this field have provided an automatic electrical connection device for the upper body and chassis of a new energy commercial vehicle to solve the problems raised in the above background technique.
