Description

Technical Field

[0001] This utility model relates to the field of battery swapping connectors, and in particular to a hydroelectric integrated quick-swap connector. Background Technology

[0002] With the support of national policies, the new energy vehicle industry has entered a period of rapid development. Battery swapping technology is an important way to replenish energy for new energy vehicles. It achieves rapid replenishment of electric vehicles by replacing batteries at swapping stations, shortening recharge time, reducing range anxiety, and improving the convenience of electric vehicle use. Battery swapping connectors require both water-cooled and electric quick-swap connectors. Water-cooled quick-swap connectors are used for quick swapping of liquid-cooled systems, while electric quick-swap connectors are used for quick replacement of high-voltage, low-voltage, and grounding components. Existing water-cooled and electric quick-swap connectors are generally two independent, separate connectors. Their drawbacks are: firstly, as two independent devices with limited functionality, they can only achieve quick swapping of either the liquid-cooled system or the power system, requiring independent assembly, increasing assembly time and procedures, and reducing assembly convenience; secondly, each has its own mounting panel and matching mechanism, resulting in more parts, a more complex structure, and higher mold and manufacturing costs; and thirdly, they require larger mounting panels and product layout space, increasing product size and hindering product structure arrangement. Utility Model Content

[0004] According to one aspect of the present invention, a water and electricity integrated quick-change connector includes: a plug housing, a socket housing, a water quick-change module, an electricity quick-change module, and a floating module.

[0005] The plug housing is threaded to the battery pack and has guide posts symmetrically arranged on both sides.

[0006] The socket housing is detachably connected to the vehicle body, and the vertical floating seat of the floating housing is vertically slidably connected to the middle of the inner cavity of the socket housing;

[0007] The upper water inlet and upper water outlet of the water fast-change module are symmetrically installed on both sides of the plug housing, and its lower water inlet and lower water outlet are symmetrically installed on both sides of the longitudinal and transverse floating plates inside the floating housing.

[0008] The upper housing of the electric fast-change module is connected to the middle of the plug housing and its lower housing is connected to the middle of the longitudinal and transverse floating plates. The upper housing is provided with a plug terminal assembly and the lower housing is provided with a socket assembly.

[0009] The floating module has guide sleeves symmetrically arranged on both sides of its floating shell;

[0010] When the guide post is inserted into the coupling connection guide sleeve, the upper end shell and the lower end shell are sealed and connected, and the plug terminal assembly and the socket assembly are coupled and connected, so that the conductive system is connected. The upper water inlet interface and the lower water inlet interface, the upper water outlet interface and the lower water outlet interface are coupled and connected, so that the liquid cooling system is connected, thereby forming an internally and externally isolated electrical cavity and liquid cavity.

[0011] In some embodiments, the upper end shell is integrally formed in the middle of the plug shell; the lower end of the plug shell is provided with an outer end ring, and the outer end ring is fitted with an outer sealing ring, which is matched with the battery pack mounting panel to achieve end face sealing.

[0012] In some embodiments, the inner end ring of the upper end shell at the lower end of the upper end shell is an inner sealing ring of the upper end bushing, and the inner end ring is equal in diameter to the inner wall of the lower end shell of the bushing, and the inner sealing ring interferes with the end face groove of the lower end shell of the bushing.

[0013] In some implementations, the four corners of the vertical floating seat cavity are connected to the four corners of the longitudinal and transverse floating plates by four inclined longitudinal and transverse floating spring mechanisms.

[0014] In some embodiments, a Z-axis floating spring mechanism is provided at the lower end of the vertical floating seat, and the lower end of the Z-axis floating spring mechanism is attached to the lower wall of the inner cavity of the socket housing.

[0015] In some embodiments, the four corners of the vertical floating seat are also connected to the lower wall of the socket housing cavity via Z-direction guides.

[0016] In some embodiments, the linear sleeve of the Z-direction guide is fixed inside the vertical floating seat, and the upper end of the guide shaft is fitted with the linear sleeve and the lower end is fixedly connected to the lower wall of the socket housing.

[0017] In some embodiments, two parallel floating baffles of the vertical floating seat are connected by a fixing pin to form a rectangular frame. The longitudinal and transverse floating plates float vertically and longitudinally and laterally between the two floating baffles. The guide sleeve, lower end shell, lower water inlet, and lower water outlet pass through the middle hole of the upper floating baffle.

Replacing one device allows for quick-change of both the liquid cooling system and the power system, reducing assembly time and procedures and increasing the convenience of quick-change. Second, the connector optimizes the product structure, reducing the number of parts and effectively lowering mold, manufacturing, and maintenance costs. The more compact component layout results in a smaller volume and less operating space, which is beneficial for overall design. Third, the water and electric quick-change modules are placed in independently separated sealed cavities, avoiding the impact of water dripping during quick-change and ensuring high safety. Fourth, the electric quick-change module is positioned in the middle, with the water quick-change modules symmetrically distributed on both sides, solving the problem of uneven force distribution between the water and electric quick-change modules during coupling, resulting in smoother, faster, and less jamming insertion.
