Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an automotive pipe bracket. Background Technology

[0002] Automotive pipe brackets are an important component of automotive piping systems. They are mainly used to fix, support, and protect various pipes such as fuel lines, brake lines, and cooling lines, ensuring their stability during vehicle operation and preventing loosening, wear, or leakage due to vibration, friction, or external impact.

[0003] Currently, most automotive pipes and supports are connected by spot welding or arc welding. This connection method, due to the concentrated heating generated during welding, can cause the heat-affected zone of the material to expand. This can not only easily cause deformation of parts, but also reduce the mechanical properties and corrosion resistance of the material. This is especially true when dealing with dissimilar metal connections, such as welding steel supports to aluminum pipes. Furthermore, rigid welded joints are prone to fatigue cracks under continuous vibration, while local welding makes it difficult to guarantee the complete sealing required by the pipeline system.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, an automotive piping bracket includes a bracket 1, and further includes:

[0021] Multiple mounting holes 2 are formed at the top of the bracket 1. The bracket 1 serves as the basic load-bearing structure for connecting other components and providing support for the pipe 4. The mounting holes 2 are used for connection and installation with the vehicle body or other fixed components. A fixing block 3 is fixedly connected to the bottom of the outer wall of the bracket 1. The fixing block 3 serves to fix the pipe 4, ensuring the stability of the pipe 4 on the bracket 1 and preventing it from shaking or shifting. The pipe 4 is brazed at the bottom bend of the bracket 1. The bottom of the fixing block 3 is set at the top of the pipe 4. The pipe 4, which is used to transport liquids or gases, is brazed to effectively avoid... It avoids damage to pipe 4 caused by welding, reduces cracking of pipe 4 at the weld joint due to vibration, improves product qualification rate, and effectively enhances the reliability and durability of the entire vehicle pipe system 4. It avoids the high-temperature heat-affected zone problem of ordinary welding, does not cause deformation of the base material, and maintains the original mechanical properties of the metal. It is particularly suitable for the precision connection of thin-walled pipes. The metallurgical joint formed by brazing has high strength and good sealing performance, which can fully meet the stringent requirements of automotive pipe system 4 for leak prevention. The continuous and uniform characteristics of the brazed seam give it excellent vibration fatigue resistance and it is not easy to crack under long-term driving vibration environment.

[0022] An expansion sleeve 5 is installed on the inner wall of the mounting hole 2. An expansion cavity 6 is formed inside the expansion sleeve 5. A limit block 7 is fixedly connected to the bottom of the inner wall of the expansion cavity 6. The limit block 7 restricts the movement range of the internal components of the expansion sleeve 5, ensuring that the expansion process proceeds according to design requirements and preventing excessive movement of components. A clamping block 8 is fixedly connected to the top of the limit block 7. A threaded post 9 is threadedly connected to the top of the expansion sleeve 5. A groove 10 is formed at the bottom of the threaded post 9. The top of the clamping block 8 is located at the bottom of the groove 10. An installation plate 11 is fixedly connected to the top of the threaded post 9. An installation rod 12 is connected through the inner wall of the installation plate 11. The inner wall of the clamping block 8 is installed on the outer wall of the installation rod 12. The outer wall of the installation rod 12 is connected through the bottom of the expansion sleeve 5 and the inner wall of the limit block 7. A connecting plate 13 is fixedly connected to the top of the installation rod 12. A threaded connection is formed to the bottom of the installation rod 12. When bracket 1 needs to be installed, the nut 14 is used. The mounting rod 12 is inserted into the mounting plate 11 via the connecting plate 13 connected to the vehicle body component at the top, into the expansion sleeve 5, and further into the clamping block 8, protruding from the bottom of the expansion sleeve 5. The nut 14 is then tightened at the threaded joint of the mounting rod 12, fixing the mounting rod 12 inside the expansion sleeve 5. The mounting plate 11 is then rotated, further rotating the threaded post 9 downwards along the thread inside the expansion sleeve 5, engaging the clamping slot 10 into the top of the clamping block 8. This causes the clamping block 8 to retract along the groove 10, simultaneously locking the mounting rod 12, completing the quick installation and locking of bracket 1. The installation process is simple and efficient, significantly improving assembly efficiency. Disassembly only requires a reverse rotation for quick release, facilitating maintenance and replacement. Furthermore, in conjunction with the pipe 4 fixing block 3 and the welded structure, it ensures stable support for pipe 4 and prevents loosening due to external pulling, effectively improving the safety and durability of the automotive pipe 4 system.

[0023] Working principle: The bracket 1 and the pipe 4 are brazed, which can effectively avoid damage to the pipe due to welding, reduce cracking of the pipe at the weld due to vibration, and improve the product qualification rate. When the bracket 1 needs to be installed, first connect the connecting plate 13 to the vehicle body component, insert the mounting rod 12 into the mounting plate 11, the expansion sleeve 5 and through the clamping block 8 in sequence, and tighten the nut 14 after it protrudes from the bottom of the expansion sleeve 5 to fix the mounting rod 12. Then rotate the mounting plate 11, which drives the threaded column 9 to rotate downward along the thread in the expansion sleeve 5. Its bottom groove 10 is engaged with the top of the clamping block 8. As the threaded column 9 moves downward, the clamping block 8 is constrained by the groove 10 and contracts along its interior, while holding the mounting rod 12 tightly. During this process, the limiting block 7 restricts the movement range of the internal components of the expansion sleeve 5 to ensure that the expansion process is stable and controllable, and realizes a firm connection between the bracket 1 and the vehicle body. The whole process is simple and efficient, and easy to install and maintain.
