Description

Technical Field

[0001] This utility model relates to the field of rear cantilever bending technology, specifically to a rear cantilever bending pipe for automobiles. Background Technology

[0002] Rear suspension bends are mainly used in the automotive manufacturing industry, particularly for connecting and supporting the rear suspension system. By fixing the rear suspension bend to the rear suspension, the stability and safety of the rear suspension can be effectively improved, thereby enhancing the overall vehicle's handling performance and ride comfort.

[0003] The existing rear suspension bend tubes still have certain shortcomings in actual use: the existing rear suspension bend tubes lack protective structures, which makes the bend tubes susceptible to impact and water immersion when the car encounters vibration or wading through water, resulting in a significant reduction in the service life of the bend tubes. Based on the shortcomings of the existing technology, this utility model designs a new type of automotive rear suspension bend tube. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rear suspension bend tube for automobiles, which has the advantages of being a protective bend tube, avoiding impacts and water immersion.

[0005] This utility model provides the following technical solution: a rear suspension bend tube for automobiles, comprising a bend tube body, with fixing rings fixedly installed at both ends of the bend tube body, and four fastening holes opened inside the two fixing rings; fixing structures are fixedly installed at both ends of the bend tube body; the two fixing structures include locking pins, with an outer flap fixedly installed at one end of each locking pin, and four fastening bolts threaded inside each outer flap; an inner groove is opened inside each outer flap, and fixing tubes are fixedly installed inside the four inner grooves; hooks are hung on the outer surfaces of the four fixing tubes, and a corrugated pipe is fixedly installed on one side of each of the four hooks.

[0006] As a preferred embodiment of this utility model, a connecting structure is fixedly installed at one end of the two corrugated pipes.

[0007] As a preferred embodiment of this utility model, the two connecting structures include connecting rings, and the two connecting rings are rotatably connected to the bellows.

[0008] As a preferred embodiment of this invention, a rotating ring is fixedly installed on one side of each of the two connecting rings.

[0009] As a preferred embodiment of this utility model, four first friction pads are fixedly installed inside the rotating ring on the left side.

[0010] As a preferred embodiment of this utility model, four second friction pads are fixedly installed inside the rotating ring on the right side.

[0011] As a preferred embodiment of this invention, the curvatures of the four first friction pads and the four second friction pads can be fitted together.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This type of automotive rear suspension bend tube, through a fixed structure and a fixed ring, fixes the main body of the bend tube to the rear suspension. First, two clips are inserted into both ends of the bend tube main body. Then, after aligning the fastening bolts with the fastening holes, the outer expansion flap is fixed to the fixed ring with the fastening bolts. At this time, the outer expansion flap is tightly attached to the fixed ring. Then, after fixing it to the hook through two sections of corrugated pipe, it is hung on the fixed pipe. In this way, the bend tube main body can be protected by the corrugated pipe, which can prevent it from being hit by a collision during vehicle driving or being submerged in water after wading. At the same time, it improves the overall aesthetics of the device.

[0014] 2. In this type of automotive rear suspension bend, when the two corrugated pipes at both ends are fitted onto the outside of the bend body, the two rotating rings are aligned and rotated to make the four first friction pads and four second friction pads contact and generate friction, thereby fixing the two rotating rings and connecting the two corrugated pipe sections.

[0021] 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.

[0022] Please see Figure 1-5 A rear suspension bend for automobiles includes a bend body 1, with fixing rings 4 fixedly installed at both ends of the bend body 1. Four fastening holes 41 are provided inside the two fixing rings 4. Fixing structures 2 are fixedly installed at both ends of the bend body 1. The two fixing structures 2 include locking posts 21, with outward expansion flaps 22 fixedly installed at one end of each locking post 21. Four fastening bolts 23 are threaded inside each outward expansion flap 22. Inner grooves 24 are provided inside each outward expansion flap 22. Fixing tubes 25 are fixedly installed inside the four inner grooves 24. Hooks 26 are hung on the outer surface of each fixing tube 25. A corrugated pipe 27 is fixedly installed on one side of each hook 26.

[0023] Please see Figure 2 and Figure 5 A connecting structure 3 is fixedly installed at one end of each of the two corrugated pipe sections 27. Each connecting structure 3 includes a connecting ring 31, which is rotatably connected to the corrugated pipe 27. A rotating ring 32 is fixedly installed on one side of each connecting ring 31. Four first friction pads 33 are fixedly installed inside the left rotating ring 32. Four second friction pads 34 are fixedly installed inside the right rotating ring 32. The curvatures of the four first friction pads 33 and the four second friction pads 34 can fit together.

[0024] When the two corrugated pipe sections 27 are fitted onto the outside of the bent pipe body 1, the two rotating rings 32 are aligned, and the four first friction pads 33 and four second friction pads 34 are brought into contact and friction is generated by rotating the rotating rings 32, thereby fixing the two rotating rings 32 and connecting the two corrugated pipe sections 27.

[0025] Working principle: When a car rear suspension bend tube is used, firstly, when fixing the bend tube body 1 to the rear suspension, firstly, insert two locking pins 21 into both ends of the bend tube body 1. Then, after aligning the fastening bolts 23 with the fastening holes 41, fix the outer flap 22 to the fixing ring 4 with the fastening bolts 23. At this time, the outer flap 22 and the fixing ring 4 are tightly attached. Then, after fixing the two corrugated tubes 27 to the hooks 26, hang them on the fixing tube 25. Thus, the corrugated tubes 27 can protect the bend tube body 1. Then, when the two corrugated tubes 27 are put on the outside of the bend tube body 1, align the two rotating rings 32 and rotate the rotating rings 32 to make the four first friction pads 33 and the four second friction pads 34 contact and generate friction, so that the two rotating rings 32 are fixed, thereby connecting the two corrugated tubes 27.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
