Description

Technical Field

[0001] This utility model belongs to the field of connectors, and more specifically, it relates to a connector and a connection structure for connecting an automotive air intake and a flexible hose. Background Technology

[0002] Currently, both domestic and international gasoline vehicle condenser inlet and outlet pipe connectors are made of metal, and the connectors are directly connected to the condenser. However, due to the layout and installation requirements within the vehicle cabin, the condenser outlet needs to be bent at approximately 90 degrees about 50mm from the outlet. This bending angle is achieved by bending the connecting flexible hose. The bending angle of the flexible hose is difficult to maintain consistently, and the varying space occupied within the vehicle cabin leads to a risk of friction with surrounding components after assembly. Prolonged friction can cause wear and tear on the flexible hose, potentially resulting in air leakage. Utility Model Content

[0003] In view of the problems in the related technologies, this utility model proposes a connection structure for connecting a connector, an automotive air inlet, and a flexible hose, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

Detailed Implementation

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is a connection structure for connecting an automotive air inlet and a flexible hose, including a connector, an air inlet connector 1, and a flexible hose 3. The connector includes a bending connector 2, which includes a bending portion 21. One end of the bending portion 21 is provided with a quick-connect interface 22, and the other end of the bending portion 21 is provided with a sealing interface 23. A locking member 4 is installed on the quick-connect interface 22, which can lock and fix the quick-connect interface 22 and the external interface when they are plugged in. The outer ring of the air inlet connector 1 is provided with a groove 5. When the air inlet connector 1 and the quick-connect interface 22 are plugged in, the locking member 4 can lock and fix the air inlet connector 1 and the quick-connect interface 22 in a locked and fixed manner. The sealing interface 23 is sealed and plugged into the flexible hose 3.

[0029] During connection, the quick-connect interface 22 at one end of the bent connector 2 is inserted into the air inlet connector 1, and the locking piece 4 is engaged in the slot 5 to lock the air inlet connector 1 and the quick-connect interface 22. Then, the sealing interface 23 at the other end of the bent connector 2 is inserted into the hose 3 for sealing connection. This enables the bent connection between the air inlet connector 1 and the hose 3 without bending the hose 3 again, avoiding the problem of hose 3 rubbing and abrasion caused by the inconsistent bending angle, and improving the stability and sealing of the joint.

[0030] Specifically, the bending connector 2 is a plastic connector, which reduces the production cost of the connector compared to a metal connector.

[0031] Specifically, the locking member 4 is a U-shaped spring clip structure, and both sides of the locking member 4 are provided with locking parts 41; the outer ring of the quick-connect interface 22 is provided with a mounting groove 6, and the locking member 4 is snapped into the mounting groove 6. Both sides of the quick-connect interface 22 are also provided with through grooves 7 corresponding to the locking parts 41. The locking parts 41 extend into the interior of the quick-connect interface 22 through the corresponding through grooves 7. When the quick-connect interface 22 and the air inlet connector 1 are plugged in and connected, the U-shaped opening of the locking member 4 is first turned towards the air inlet connector 1. The two sides abut and open, so that the locking parts 41 on both sides of the locking member 4 move outward and open, without affecting the insertion connection of the quick-connect interface 22 and the air inlet connector 1. After the insertion connection is completed, the limit on both ends of the locking member 4 is released. At this time, the locking member 4 resets and retracts under its own elasticity, so that the locking parts 41 on both sides retract inward and move closer, so that the locking parts 41 on both sides respectively lock onto both sides of the slot 5, thereby locking and locking the quick-connect interface 22 and the air inlet connector 1.

[0032] Specifically, a sealing ring 13 is also fixedly installed on the inner ring of the quick-connect interface 22. When the air inlet connector 1 is inserted into the inner ring of the quick-connect interface 22, the sealing ring 13 seals against the seam between the air inlet connector 1 and the quick-connect interface 22, thereby sealing the seam between the air inlet connector 1 and the quick-connect interface 22 to improve the sealing performance of the interface.

[0033] Specifically, the outer ring of the quick-connect interface 22 is fixedly equipped with a protective cover 8 located on one side of the two ends of the locking member 4. The protective cover 8 can shield and protect the two ends of the locking member 4 to prevent other parts in the vehicle compartment from scratching or touching the two ends of the locking member 4.

[0034] Specifically, a limiting groove 11 is provided on the protective cover 8, and a lever 9 is rotatably installed in the limiting groove 11. One end of the lever 9 is rotatably connected to the end of the locking member 4, and the other end of the lever 9 extends to the outside of the protective cover 8. When the air inlet connector 1 and the quick-connect interface 22 are inserted or removed, the operator can use two fingers to push the outer ends of the lever 9 on both sides of the quick-connect interface 22 inward to close them. At this time, the inner end of the lever 9 rotates open, thereby driving the two ends of the locking member 4 to open outward, making it easier to open the locking member 4, so as to facilitate the insertion and removal connection between the air inlet connector 1 and the quick-connect interface 22.

[0035] Specifically, a slide groove 10 is provided on one side of the lever 9, and a slide bar 12 is slidably installed in the slide groove 10. The slide bar 12 can move and extend along the slide groove 10. When the slide bar 12 slides and retracts into the slide groove 10, the slide bar 12 abuts against the inner wall of the lever 9 and the limiting groove 11 to lock the lever 9 in the limiting groove 11.

[0036] When it is necessary to open the two ends of the locking member 4 outward, the slide bar 12 slides outward along the slide groove 10 to extend, thereby increasing the length of the outer end of the lever 9, making the lever 9 a force-saving lever. This allows the operator to push the two ends of the locking member 4 outward with less force when the slide bar 12 is pushed inward. When the air inlet connector 1 and the quick-connect interface 22 are inserted and removed, and the locking member 4 is engaged with the slot 5, the slide bar 12 slides inward along the slide groove 10 to retract, so that the slide bar 12 abuts against the inner wall of the lever 9 and the limiting groove 11, thereby locking the lever 9 in the limiting groove 11. This locks the end of the locking member 4 through the lever 9, keeping the locking member 4 in a closed and locked state, thereby improving the stability of the connection between the air inlet connector 1 and the quick-connect interface 22.
