Description

Technical Field

[0001] This utility model relates to the field of automotive cooling system flange technology, specifically a three-port flange quick connector for automotive cooling systems. Background Technology

[0002] With the rapid advancement and upgrading of technology, automobile manufacturing technology is also constantly innovating. A car consists of an engine, transmission, chassis, body, electrical system, tires, and other major components. These components work together to ensure the normal operation of the car. There are also some smaller components and systems in a car, such as the cooling system, fuel system, and air conditioning system. The cooling system plays an important role in a car, ensuring that the engine operates within a suitable operating temperature range, preventing overheating, regulating the engine temperature, and improving the stability and reliability of the engine during operation. However, when connecting cooling pipes, most existing pipe joints are fixed by welding, and tools are required to separate the pipes when disassembling them. This makes the installation, disassembly, maintenance, and repair of the pipes extremely inconvenient. Furthermore, when a joint is damaged, the entire component must be replaced, making maintenance and repair quite troublesome. Utility Model Content

[0003] The purpose of this invention is to provide a quick-connect plug for a three-port flange automotive cooling system, in order to solve the problem mentioned in the background art that the connecting pipes in the cooling pipeline system cannot be quickly plugged in and installed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a three-port flange quick connector for an automotive cooling system, comprising an end cap, wherein the end cap is symmetrically designed and has a through hole on one side surface; a cavity is fixedly installed on the outer surface of the end cap, and three insertion interfaces are evenly fixed on the outer surface of the cavity; and an insertion mechanism is provided on the outer surface of the insertion interfaces, which enables the connector to be quickly connected and fixed, facilitating the disconnection and connection of the connected cooling pipes.

[0005] Preferably, the insertion mechanism includes: an insertion port, which is evenly opened on the outer surface of the insertion interface, and an inclined sliding groove is provided on the side of the insertion interface near the end cap, and the outer surface of the inclined sliding groove is in contact with the outer surface of the insertion port.

[0006] By adopting the above technical solution, the plug can be inserted into the inside of the socket and pass through the insertion port. Then, by twisting the plug, the outer surface of the plug can move along the direction of the inclined slide groove, so that the outer surface of the plug can fit tightly against the outer surface of the socket, realizing the quick connection and disconnection of the plug and the socket, and facilitating the separation of the plug and the socket.

[0007] Preferably, the end cap away from the through hole has a waist-shaped hole fixedly provided, and the waist-shaped hole and the through hole are symmetrically designed.

[0008] Using the above technical solution, the end cap can be fixed to the automotive component that needs to be fixed through the through hole and the oblong hole. The oblong hole allows the end cap to move within a certain range, making it convenient to make fine adjustments to the position of the end cap. Furthermore, if the end cap is damaged, it can be easily disassembled and replaced without replacing the entire component.

[0009] Preferably, a shell reinforcing rib is fixedly installed on the outer surface of the end cap, and the other end of the shell reinforcing rib is connected to the cavity. A reinforcing block is provided on the outer surface of the cavity, and the reinforcing block is fixedly connected to the insertion interface.

[0010] By adopting the above technical solution, the connection strength between the end cap and the cavity can be strengthened by the shell reinforcing ribs, and the connection strength between the cavity and the insertion interface can be strengthened by the reinforcing blocks. This saves the materials required for the overall flange manufacturing, while maintaining the strength of the connection, reducing the chance of damage, and reducing its own weight.

[0011] Preferably, a sliding snap-fit ​​mechanism is provided between the end cap and the cavity. The plug can be quickly fixed by the sliding snap-fit ​​mechanism without the need for screws or other items. There is no need to worry about the plug falling off due to vibration or other reasons, and the situation of cracks in the cavity caused by screwing in screws is reduced.

[0012] By adopting the above technical solution, the damage caused by screws being screwed into the outer surface of the cavity can be reduced, the probability of the cavity being cracked during screw fixing can be reduced, and the overall service life of the flange can be improved.

[0013] Preferably, the sliding snap-fit ​​mechanism includes: a baffle plate, which is fixedly installed on the outer surface of the cavity. The baffle plate is arc-shaped and located on one side of the plug interface. A slot is formed on the outer surface of the baffle plate, and a snap pin is fixedly installed inside the slot. The snap pin and the slot are respectively engaged with the outer surface of the plug.

[0014] Using the above technical solution, when the plug is inserted into the socket and rotated, the outer surface of the plug will come into contact with the outer surface of the baffle and gradually move with the rotation, eventually falling into the slot. At the same time, as it falls, the locking pin will engage with the outer surface of the plug, so that the plug will automatically lock after rotating into place. This prevents the plug from rotating and detaching from the socket due to vibration or pulling during use, reducing the risk of liquid leakage from the cooling system during use.

[0015] Preferably, both ends of the end cap are fixedly equipped with protruding reinforcing ribs, which surround the outer surfaces of the through hole and the waist-shaped hole. The outer surface of the end cap away from the insertion interface is fixedly equipped with a protruding outlet, which is inserted into the outer surface to be fixed, and the protruding outlet is located below the cavity.

[0016] By adopting the above technical solution, the connection strength between the through hole and the oblong hole can be strengthened by the protruding reinforcing rib, so that the through hole and oblong hole can withstand greater pressure from the screw when fixed. At the same time, the weight of the flange itself can be reduced and its strength can be improved. In addition, when fixing the end cover, the protruding outlet can be inserted into the interior of the automotive parts.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the quick-connect plug for the three-port flange automotive cooling system:

[0018] 1. The end cap can be fixedly installed on the outer surface of the vehicle parts through the through hole and the oblong hole. Then, the plug can be inserted into the inside of the connector and one end of the plug can be passed through the insertion hole. Then the plug can be rotated to move the outer surface of the plug along the direction of the inclined slide, so that the outer surface of the plug and the outer surface of the connector are tightly fitted to prevent the liquid in the cooling system from leaking out, and the plug and the pipe can be quickly connected.

[0019] 2. After prolonged use, flanges inevitably wear out or break. At this time, the screws can be removed from the through hole and the oblong hole, and then the end cover can be easily removed from the automotive parts and replaced. This allows the damaged joints of automotive parts to be replaced without replacing the entire part, which is convenient for maintenance and can reduce maintenance costs.

[0020] 3. When the plug is inserted into the socket and rotated, the outer surface of the plug will slide on the outer surface of the baffle, allowing one end of the plug to be inserted into the slot and engaged with the locking post. This allows the plug to be fixed to the outer surface of the cavity without the need for screws, reducing the cracks caused by screws being screwed into the cavity and improving the overall service life of the flange.

[0029] 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.

[0030] Please see Figure 1-7 This utility model provides a technical solution: a three-port flange quick connector for an automotive cooling system, including an end cover 1. The end cover 1 has a symmetrical design, and a through hole 2 is opened on one side surface of the end cover 1. A cavity 4 is fixedly installed on the outer surface of the end cover 1, and three plug interfaces 8 are evenly fixed on the outer surface of the cavity 4. A plug-in mechanism is provided on the outer surface of the plug interface 8. The plug can be quickly connected and fixed through the plug-in mechanism, which facilitates the disconnection and connection of the connected cooling pipes.

[0031] The cavity 4 connects to the three connectors 8, allowing multiple cooling pipes to be gathered together, facilitating the centralized delivery of multiple cooling lines to the heat dissipation device.

[0032] The insertion mechanism includes: an insertion port 9, which is evenly distributed on the outer surface of the insertion interface 8, and an inclined groove 11 is provided on the side of the insertion interface 8 near the end cover 1, and the outer surface of the inclined groove 11 is in contact with the outer surface of the insertion connector.

[0033] When a quick connection of the plug is required, simply insert one end of the plug into the inside of the socket 8 and pass one end of the plug through the insertion port 9. Then, rotate the plug to slide it along the inclined slide groove 11 so that the outer surface of the plug can fit tightly against the outer surface of the socket 8. This prevents the leakage of liquid cooling medium after the flange and the plug are connected, and allows the plug and flange to be quickly connected and disconnected for easy maintenance.

[0034] An oblong hole 3 is fixedly provided at the end of the end cap 1 away from the through hole 2, and the oblong hole 3 and the through hole 2 are designed symmetrically.

[0035] The end cap 1 can be quickly and securely installed on the outer surface of the automotive interior parts through the through hole 2 and the oblong hole 3, making it easy to replace the flange after it is damaged without replacing the entire part, thus reducing the cost of maintenance and replacement.

[0036] A housing reinforcing rib 14 is fixedly installed on the outer surface of the end cap 1, and the other end of the housing reinforcing rib 14 is connected to the cavity 4. A reinforcing block 10 is provided on the outer surface of the cavity 4, and the reinforcing block 10 is fixedly connected to the insertion interface 8.

[0037] The shell reinforcing rib 14 can strengthen the connection between the end cap 1 and the cavity 4, while the reinforcing block 10 can strengthen the connection between the cavity 4 and the insertion interface 8, so that the insertion interface 8 and the cavity 4 will not leak due to the pressure generated during use. At the same time, it can reduce the material required for flange manufacturing and reduce its own weight.

[0038] A sliding snap-fit ​​mechanism is provided between the end cap 1 and the cavity 4. The plug can be quickly fixed by the sliding snap-fit ​​mechanism without the need for screws or other items. There is no need to worry about the plug falling off due to vibration or other reasons, and the situation of cracks appearing in the cavity 4 caused by screwing in screws is reduced.

[0039] When fixing the plug, the plug can be fixed to the outer surface of the cavity 4 without screws, reducing the cracking of the cavity 4 caused by screws, allowing the flange to be used for a longer period of time and extending the overall service life of the flange.

[0040] The sliding snap-fit ​​mechanism includes: a baffle 5, which is fixedly installed on the outer surface of the cavity 4. The baffle 5 is arc-shaped and located on one side of the plug interface 8. A slot 6 is provided on the outer surface of the baffle 5, and a snap post 7 is fixedly installed inside the slot 6. The snap post 7 and the slot 6 respectively engage with the outer surface of the plug.

[0041] When the plug is inserted into the socket 8 and rotated, the plug will slide on the outer surface of the baffle 5 and be inserted into the slot 6 and the pin 7, so that the plug can be fixed on the outer surface of the baffle 5. This prevents the plug and flange from rotating and separating from the socket 8 due to vibration or other reasons, reducing the risk of liquid leakage in the cooling system.

[0042] Both ends of the end cap 1 are fixedly installed with protruding reinforcing ribs 13, and the protruding reinforcing ribs 13 surround the outer surface of the through hole 2 and the waist-shaped hole 3. The outer surface of the end cap 1 away from the insertion interface 8 is fixedly installed with a protruding outlet 12, and the protruding outlet 12 is inserted into the outer surface to be fixed, and the protruding outlet 12 is located below the cavity 4.

[0043] The protruding reinforcing rib 13 can strengthen the connection between the through hole 2 and the waist-shaped hole 3, so that the screw will not be damaged by compression when it is inserted and screwed into the through hole 2 and the waist-shaped hole 3. After the end cap 1 is fixed, the protruding outlet 12 can be inserted into the outer surface of the automotive part.

[0044] 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.
