Description

Technical Field

[0001] The present application relates to the technical field of new energy vehicle components, and in particular to a dustproof quick-change water-cooling joint. Background Art

[0002] Quick-change water cooling connectors are used at the connection between the body and battery in new energy vehicles to cool the batteries. When the battery pack is assembled, there will be some misalignment between the body and the battery connector. Therefore, the quick-change water cooling connectors are designed with a floating feature to absorb this misalignment. The floating structure incorporates a spring inserted into the connector, which is then positioned between mounting plates and protected by a cover. The spring's lateral force allows for deflection during assembly and resets the connector when the battery pack is separated.

[0003] Related prior art, such as Chinese patent application number CN202021439315.3, "New Self-Sealing Quick-Change Connector for Water-Cooling Pipes," discloses a male connector comprising a fixing plate, a pipe connector, and a male connector body. One end of the male connector body passes through the fixing plate and is threadedly connected to the pipe connector. A wave spring is provided between the end of the pipe connector and the fixing plate, and the other end of the male connector body is restrained below the fixing plate. The addition of the wave spring prevents the connector from being bent by the hose and automatically corrects the angle.

[0004] With the increasing popularity of new energy vehicles, they are subject to harsh driving conditions, and foreign matter such as mud and sand may adhere to the surface and gaps of the floating area of ​​the water-cooling joint. The gap between the fixing plate and the structure mounted on it can easily accumulate mud and sand over time as the vehicle moves, potentially causing the floating function to fail. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide a dustproof quick-change water-cooling joint, which provides overall protection for the floating area of ​​the water-cooling joint to prevent mud and sand from entering the floating area.

[0006] The technical solution adopted in this application is: a dustproof quick-change water-cooling joint, including a fixed plate, an upper protective part is provided on the upper surface of the fixed plate, and the upper protective part is a cylindrical structure as a whole. The piping connector is located in the upper protective part, and there is a distance between the piping connector and the inner wall surface of the upper protective part. The bottom surface of the upper protective part is attached to the upper surface of the fixed plate, and a lower protective part is provided on the lower surface of the fixed plate. The lower protective part is a cylindrical structure as a whole, the male head body is located in the lower protective part, and there is a distance between the male head body and the inner wall surface of the lower protective part, and the top surface of the lower protective part is attached to the lower surface of the fixed plate.

[0007] Compared with the prior art, the advantage of the present application is that, within a limited structural space, it cleverly provides overall protection for the upper and lower surfaces of the fixed plate without affecting the function of the product. Specifically, the piping connector is located in the upper protective part, and there is a gap between the piping connector and the inner wall surface of the upper protective part. The male body is located in the lower protective part, and there is a gap between the male body and the inner wall surface of the lower protective part. The structural setting of the present application does not affect the function of the product, especially in the case of floating function, and realizes the protection of the upper and lower connection structures of the fixed plate. The bottom surface of the upper protective part is attached to the upper surface of the fixed plate, and the top surface of the lower protective part is attached to the lower surface of the fixed plate. The setting of the upper and lower protective parts effectively increases the dust-proof structure of the product and reduces the risk of foreign matter such as dust and sand entering the floating gap.

[0008] In some embodiments of the present application, the cross-section of the upper protective member is runway-shaped, and both ends of the upper protective member in the length direction extend outward to form a mounting plate, and the mounting plate partially extends out of the fixed plate.

[0009] In some embodiments of the present application, a plurality of triangular reinforcement plates are provided between the mounting plate and the outer surface of the upper protective member, connecting the upper protective member and the mounting plate. The structural arrangement of the reinforcement plates effectively improves the structural strength of the mounting plate and ensures reliable and stable installation.

[0010] In some embodiments of the present application, the top surface of the upper guard has an 8-shaped opening, through which two pipe connectors pass. The upper guard with the above-described structural design can accommodate common dual-channel water-cooling joints and is the preferred structural setting of the present application.

[0011] In some embodiments of the present application, the lower protective component includes a protective bracket and a soft rubber sleeve, the protective bracket is arranged to fit the lower surface of the fixed plate, and the soft rubber sleeve and the protective bracket are injection molded.

[0012] In some embodiments of the present application, the protective bracket is a stepped tubular structure with the upper section having a larger diameter than the lower section, the upper section of the protective bracket is a waist-shaped tubular structure, and the lower end of the protective bracket is a waist-shaped tubular structure; the protective bracket is made of plastic material.

[0013] In some embodiments of the present application, the soft rubber sleeve is a waist-shaped tubular structure made of rubber, with the lower end of the soft rubber sleeve conforming to the battery pack mounting surface. The soft rubber sleeve can deform to conform to the battery pack mounting surface, absorbing the gaps caused by the Z-axis combination and providing better protection. In the present application, the protective bracket and soft rubber sleeve can be integrally injection molded using a two-color mold, which is a mature manufacturing process.

[0014] In some embodiments of the present application, both ends of the protective bracket in the length direction extend outward to form mounting columns, which extend outside the fixing plate and correspond to the fixing plate. The mounting columns and the fixing plate are locked by bolts.

[0015] In some embodiments of the present application, two mounting posts are provided at each end of the protective bracket's length, and the two mounting posts are fixedly connected to form a single unit. The two mounting posts can be integrated into a single structure to enhance the structural strength of the component. Specifically, in this application, one end is secured with two bolts, for a total of four bolts. The upper and lower protective members are connected using four self-tapping screws, a convenient and reliable connection method.

[0016] In some embodiments of the present application, the two ends of the protective bracket in the width direction extend outward to form a clamping member, and the ends of the clamping member are bent to fit the side of the fixing plate. The clamping members extend from both sides of the protective bracket to clamp the fixing plate to limit the position of the protective bracket.

[0017] The above embodiments can be combined arbitrarily based on the common knowledge in this field. BRIEF DESCRIPTION OF THE DRAWINGS
