[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a welded pipeline for a new energy vehicle thermal management system, comprising a rigid pipe 1 and a rigid pipe 2. A welding bracket 3 is provided on the outer side of the rigid pipe 1. A limiting groove 5 is formed inside the welding bracket 3. A welding wire 4 is provided on the side wall of the welding bracket 3. A connecting block 6 is fixedly connected to the outer wall of the welding bracket 3. A connecting block 7 is provided on the outer wall of the connecting block 6. A welding bracket 8 is fixedly connected to the outer wall of the connecting block 7. The side wall of the welding bracket 8 is provided on the outer wall of the rigid pipe 2. An installation component is provided on the outer side of the connecting block 6, and the installation component is used to connect the connecting block 6 and the connecting block 7.

[0025] Specifically, rigid pipe 1 is welded to welding bracket 3, and rigid pipe 2 is welded to welding bracket 8. An inwardly inclined limiting groove 5 is opened at the welding position of welding bracket 3 and rigid pipe 1, and a similar inwardly inclined mechanism is opened at the welding position of welding bracket 8 and rigid pipe 2. At the same time, rigid pipe 1 and rigid pipe 2 are connected by a support structure composed of welding bracket 3, connecting block 6, connecting block 7 and welding bracket 8. Connecting block 6 and connecting block 7 are quickly aligned and installed by locking block 9 and locking groove 10. Before welding, welding wire 4 is placed in the limiting groove 5. The inwardly inclined structure can eliminate the deformation of the heated parts. During the welding process, the flux and welding liquid generated by welding wire 4 will not flow into the non-welding area of ​​the parts, which can make the rigid pipe 1 and welding bracket 3 fully fused, and the welding quality is guaranteed. This can prevent the quality defects of false welding, missing welding and weld beads, ensure the connection strength of rigid pipe 1 and welding bracket 3, improve the reliability and stability of the thermal management system, and further adapt to the performance of the whole vehicle.

[0026] Reference Figure 3 The installation components include a card block 9, the outer wall of which is fixedly connected to the outer wall of the first connecting block 6, and a card slot 10 is provided inside the second connecting block 7.

[0027] Specifically, since the card block 9 is fixedly connected to the connecting block 6, the card block 9 is inserted into the slot 10, and the slot 10 is opened inside the connecting block 7. At this time, the connecting block 6 and the connecting block 7 are aligned and installed to avoid the bracket from tilting.

[0028] Reference Figure 3 The outer wall of the card block 9 is located inside the connecting block 2 7, and the outer wall of the card block 9 is located inside the card slot 10.

[0029] Specifically, by matching the internal shape of the card slot 10 with the external shape of the card block 9, the card block 9 fits snugly with the card slot 10, thereby enhancing the stability of the connection between the connecting block 1 6 and the connecting block 2 7.

[0030] Reference Figure 1 and Figure 2 The outer side of the welding wire 4 is set on the outer wall of the rigid tube 1, and the outer wall of the welding wire 4 is set inside the limiting groove 5.

[0031] Specifically, welding wire 4 is used to weld the rigid tube 1 to the welding bracket 3, and the opening of the limiting groove 5 prevents the welding liquid generated during the welding of welding wire 4 from flowing out of the welding area.

[0032] Reference Figure 2 and Figure 4A fixing block 11 is fixedly connected to the outer wall of connecting block 16, and a fixing block 28 is fixedly connected to the outer wall of connecting block 27. The outer wall of fixing block 11 is disposed on the outer wall of fixing block 28. A rotating block 12 is rotatably connected to the side wall of fixing block 11, and a rotating block 27 is rotatably connected to the side wall of fixing block 11. A handle 16 is fixedly connected to the outer side of rotating block 12. A limit component is disposed on the side wall of fixing block 11, and the handle 16 is connected to the limit component. The limit component includes a limit block 13, the outer wall of which is fixedly connected to the side wall of fixing block 11, and a limit block 24 is fixedly connected to the side wall of fixing block 11. The outer wall of the handle 16 is disposed on the side wall of limit block 24.

[0033] Specifically, by moving the handle 16 to disengage it from the interior of the limiting block 14, the rotating block 12 rotates along the inner walls of the fixing block 11 and the fixing block 18 under the influence of the handle 16. Simultaneously, the rotating block 17 rotates along the inner walls of the fixing block 11 and the fixing block 18 under the influence of the rotating block 12. When the handle 16 reaches the limiting block 13 and engages there, the rotating block 17 disengages from the interior of the fixing block 11, and the rotating block 12 disengages from the interior of the fixing block 18. Thus, the rotating blocks 12 and 17 are no longer stuck between the fixing blocks 11 and 18. At this point, fixing block 11 and fixing block 2 can be separated, and then connecting block 16 and connecting block 2 can be separated. The handle 16 is made of stainless steel, while limiting block 13 and limiting block 2 are both made of magnetic material. This allows limiting block 13 and limiting block 2 to fix the handle 16 with magnetic force, so as to prevent the handle 16 from falling off and causing fixing block 11 and fixing block 2 to separate due to external impact. This achieves the effect of convenient and quick removal and installation of rigid pipe 1 and rigid pipe 2, while maintaining the stability of rigid pipe 1 and rigid pipe 2 and preventing external impact from separating rigid pipe 1 and rigid pipe 2.

[0034] Reference Figure 4 The outer wall of rotating block 12 is set on the outer wall of rotating block 2 17. The outer wall of rotating block 12 is rotatably connected to the side wall of fixed block 2 18. The outer wall of rotating block 2 17 is rotatably connected to the side wall of fixed block 2 18.

[0035] Specifically, rotating block 12 and rotating block 2 17 are installed between fixed block 11 and fixed block 2 18 by offset installation to connect fixed block 11 and fixed block 2 18.

[0036] Reference Figure 4 The fixed block 11 has a groove 15 inside, the outer wall of the handle 16 is set inside the groove 15, the outer wall of the rotating block 12 is rotatably connected to the inside of the groove 15, and the outer wall of the rotating block 2 17 is rotatably connected to the inside of the groove 15.

[0037] Specifically, the slide 15 provides rotation space for the grip 16 and limits the rotation range of the grip 16. Since the first rotating block 12 rotates synchronously with the grip 16 and the second rotating block 17 rotates under the drive of the first rotating block 12, the rotation range of the first rotating block 12 and the second rotating block 17 is thus limited.

[0038] Working principle: By opening a limiting groove 5 at the welding position of welding bracket 1 3 and the same internal inclined mechanism at the welding position of welding bracket 2 8, the welding wire 4 is placed in the limiting groove 5 before welding. The internal inclined structure can eliminate the deformation of the heated parts. During the welding process, the flux and the welding liquid generated by the welding wire 4 will not flow into the non-welding area of ​​the parts, which can make the welding between the rigid pipe 1 and the welding bracket 1 3 sufficient. This can prevent welding defects, ensure the connection strength of the pipe welding position after welding, and improve the reliability and stability of the thermal management system to adapt to the performance of the whole vehicle.

[0039] By rotating the handle 16, the first rotating block 12 rotates under the influence of the handle 16, and the second rotating block 17 rotates synchronously under the influence of the first rotating block 12. Finally, the handle 16 reaches the limit block 13, and the first fixing block 11 and the second fixing block 18 can be separated. Then the first connecting block 6 and the second connecting block 7 can be separated. This allows users to install the rigid pipe 1 and the rigid pipe 2 efficiently, while ensuring the stability of the rigid pipe 1 and the rigid pipe 2 and preventing external impacts from separating the rigid pipe 1 and the rigid pipe 2.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
