Description

Technical Field

[0001] This utility model belongs to the field of automobile manufacturing, and specifically relates to an oil pipe connection structure with assembly error prevention function. Background Technology

[0002] In a vehicle, the joints that bridge the gap between soft and hard pipes play a crucial role in the entire piping system. These joints are usually the weakest point in the entire piping system, and their manufacturing process can affect the quality of the entire piping system, and even the performance of the product and the safety of the entire vehicle.

[0003] Currently, various types of oil lines are widely used in vehicles, and the flexible-rigid connection between rubber hoses and rigid hoses is favored by designers. The rigid hose portion effectively shapes the entire pipeline, maintaining the required clearance with surrounding components, while the rubber hose portion increases the flexibility of the pipeline and reduces vibration in the entire pipeline system. In this context, the joint where the flexible and rigid hoses transition plays a crucial role in the entire pipeline system. This joint is often the weakest point in the entire pipeline system, and its manufacturing process affects the quality of the entire pipeline, even impacting product performance and vehicle safety.

[0004] In existing technologies, the main structural forms of hose and metal pipe joints include a metal pipe with a protruding ring at the end, which is then connected to the hose using a clamp, or a metal pipe with a limiting protrusion, the hose end pressing against the protrusion, and the hose being secured by a metal sleeve. The metal pipe has at least two circumferential grooves at the end extending into the hose, each groove containing a tension ring. Both of these structural forms have certain drawbacks. Firstly, the clamp connection structure with the metal pipe sleeve has low pressure resistance and is prone to detachment. Secondly, the groove and tension ring structure is complex, costly, and the assembly process of the hose and metal sleeve is uncontrollable. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a riveting joint between a rubber hose and a rigid pipe with a manufacturing error-proof function. This structure has advantages such as manufacturing error-proof and high structural strength.

[0006] To achieve the above objectives, the riveting joint structure with error-proof function adopted in this utility model includes: a rigid pipe end, a rubber hose end, and an envelope layer. The inner wall surface of the rubber hose end contacts the outer wall surface of the rigid pipe end, and is then riveted and fixed by the envelope layer. An opening is made in the envelope layer of the joint to monitor the insertion position of the rubber hose end, preventing incomplete insertion and insufficient strength of the riveting joint, which could lead to failure of the pipeline or even the entire vehicle.

[0007] Furthermore, the rigid tube end is fixed to the envelope layer by an extrusion boss.

[0008] Furthermore, the connector envelope layer is provided with openings.

[0009] Furthermore, the outer surface of the rigid tube end has a threaded groove.

[0010] After the inner wall of the rubber hose and the outer wall of the rigid tube end of this invention are fitted together, the rubber hose and the rigid tube are riveted together by extruding the envelope layer, thereby enhancing the structural strength. Furthermore, the addition of openings in the envelope layer allows for monitoring of the hose insertion depth, preventing insufficient insertion depth from causing insufficient strength in the riveted structure and resulting in component failure.

[0015] 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.

[0016] Implementation, for example Figures 1 to 3 As shown, the riveted joint structure includes a rigid tube end 1, a rubber hose end 2, an envelope layer 3, and an opening 4 in the envelope layer. The rigid tube end 1 is connected to the riveted envelope layer 3 via a pressing boss. The rubber hose end 2 is pre-connected to the rigid tube end 1 via a threaded groove. The envelope layer 3 is then pressed to form a riveted joint, ensuring the joint's sealing and strength. The opening 4 in the envelope layer 3 can monitor the insertion depth of the rubber hose end 2 during the pre-connection with the rigid tube end 1, preventing improper assembly that could lead to component or vehicle failure.

[0017] In use, when the hose end 2 is pre-connected to the rigid tube end 1, the insertion depth of the hose end 2 can be monitored through the opening 4 on the envelope layer 3, and the next riveting process can be carried out by detecting the insertion position of the hose end 2 with a laser.

[0018] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
