Description

Water-cooling pipeline inserts connection structure soon Technical Field The invention belongs to the technical field of battery pack connection structures, and particularly relates to a water-cooling pipeline quick-plug connection structure. Background The electric automobile is a development direction of a new energy automobile, and a battery pack is used for storing electric energy as a power source for driving the automobile to run. In order to ensure certain total electric quantity and output voltage requirements, the electric automobile needs to be provided with a certain number of battery packs, and each battery pack is connected through copper bars to form a battery module, so that the safety of a battery pack is improved, and the battery pack is assembled in a shell to form the battery pack. The battery pack is charged and discharged to generate heat to raise the temperature, the temperature is too high to adversely affect the performance and service life of the battery, even thermal runaway is caused to damage personal safety, so that the battery pack in use must be cooled, meanwhile, in a region with lower air temperature, the battery pack is required to be preheated in advance when the temperature is lower, the battery pack is required to be charged, the effect of quick charging is achieved, and therefore, a temperature control device is required to be added to facilities for arranging the battery pack in a battery bottom bin, a battery changing cabinet and the like and charging and discharging. In the traditional technical scheme, the whole water cooling plate paved in the frame is contacted with the battery pack inserted into the battery compartment of the vehicle, so that the heat exchange effect is achieved. However, each battery pack is independently provided with a water cooling plate, so that the heat exchange effect can be ensured, but the water cooling joint is relatively difficult to install and detach, so that the operation burden of staff is increased in the process of disassembling and replacing the multi-battery pack, and the operation process of maintaining and replacing the battery pack is limited to a large extent. Disclosure of Invention The invention aims to provide a water-cooling pipeline quick-plug connection structure which is put into use so as to solve the problems in the background technology. In order to achieve the purpose, the invention provides the technical scheme that the quick-plugging connecting structure of the water-cooling pipeline comprises plugging pipes capable of being plugged and connected, plugs are radially and slidably arranged in the two plugging pipes, one end of the plugging pipe behind each plug is sealed through a supporting seat, and a spring for pushing a mortgage part of each plug to be attached to the inner wall of the corresponding plugging pipe to seal a port of the corresponding plugging pipe is arranged between the supporting seat and each plug; when the insertion pipes are inserted, the plugs of the two insertion pipes are pushed to slide mutually, the spring is compressed, and the pushing parts of the plugs are separated from the inner wall of the insertion pipe. Preferably, the cannula comprises a thin pipe section opposite to the insertion end and a thick pipe section connected to the rear end of the thin pipe section; The spring pushes the plug to be attached to the inner wall of the connecting section of the thin pipe section and the thick pipe section, and the insertion pipe is closed. Preferably, one end of the plug is a flow-dispersing part which is arranged in the thin pipe section in a sliding way, and the flow-dispersing part is provided with a flow-guiding hole A opposite to the port of the cannula and a flow-guiding hole B arranged on the circumferential surface of the plug; the flow-dispersing section has two positional states within the cannula: the first step is that the spring is compressed, the flow-dispersing part slides along the thin pipe section to the thick pipe section, at the moment, the flow-guiding hole B of the flow-dispersing part is communicated with the thick pipe section, and the opposite insertion pipe is in a conducting state; secondly, the spring is reset, the flow dispersing part slides from the thick pipe section to the thin pipe section, at the moment, the flow guiding hole B of the flow dispersing part is sealed by the inner wall of the thin pipe section, and the opposite inserting pipe is in a sealed state. Preferably, the inner wall of the joint section of the thick pipe section and the thin pipe section is provided with an annular cambered surface, and the outer ring of the plug is correspondingly provided with a sealing ring; After the spring pushes the plug to reset, the round table-shaped sealing ring is attached to the annular cambered surface of the connecting section.
