[0045] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, the water outlet pipe seat 100 provided in this embodiment is provided with a plurality of water outlets 120 on the pipe seat body 110, which can be connected to other multiple parts through multiple water outlet pipes, and is connected to the cylinder head of the engine through the water outlet 120. Compared with the structure in the related art that adopts multiple parts to be directly connected to the cylinder head of the engine, the water outlet pipe seat 100 provided in this embodiment has the advantages of high integration and small space occupation.

[0046] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, the outlet pipe seat 100 provided in this embodiment is provided with three outlets 120, namely, a coolant outlet 121, a HVAC outlet 122, and an EGR system cooling outlet 123, and a temperature sensor 140 for testing the temperature of cooling water or coolant. Each outlet is provided with a positioning boss 170 for limiting the installation position of the nozzle of the radiator hose. The connection structure between the outlet pipe seat and the radiator hose is used to connect one of the outlets and the nozzle of the radiator hose so that the two can be quickly fixedly connected. In this embodiment, the connection between one of the outlets 120, namely, the coolant outlet 121 and the nozzle of the radiator hose is used as an example to illustrate a connection structure between a water outlet pipe seat and a radiator hose provided in this embodiment.

[0047] The connection structure includes: a first joint 1 and a second joint 2.

[0048] The first joint 1 is connected to the water outlet 120, and a recessed portion 101 is provided on the outer side of the first joint 1; the second joint 2 is connected to the pipe mouth of the radiator hose, and a movable protrusion 301 is provided on the inner side of the second joint 2, and the movable protrusion 301 is suitable for moving along the radial direction of the second joint 2.

[0050] Furthermore, if Figure 1-Figure 3 As shown, after the first connector 1 and the second connector 2 are connected, the pipe mouth of the coolant outlet 121 in the outlet 120 is suitable for abutting against the inner wall of the pipe mouth of the radiator hose, and cooperates with the sealing device to seal the connection position of the two pipe mouths, thereby ensuring the sealing of the cooling water or coolant flowing through the pipe mouth connection position.

The movable protrusion 301 can realize radial movement along the second joint 2, that is, the movable protrusion 301 can expand along the radial direction of the second joint 2 and then reset.

[0052] As an embodiment, the movable protrusion 301 is configured as a spring movable block connected to the inner wall of the second joint 2. When the second joint 2 is sleeved to the first joint 1, the outer wall of the first joint 1 abuts against the spring movable block to expand it radially, so that the second joint 2 passes through the outer wall of the first joint 1, and abuts against the recessed portion 101 of the first joint 1 until it fails. The spring movable block elastically resets and falls into the recessed portion 101, completing the connection between the first joint 1 and the second joint 2.

[0053] As another embodiment, Figure 1-Figure 3As shown, a movable protrusion 301 is formed by setting a clamping member 3 clamped on the hollow part 201 of the second joint 2, and the movable protrusion 301 is set as a partial structure of the clamping member 3 exposed in the hollow part 201. When the second joint 2 is sleeved to the first joint 1, the outer wall of the first joint 1 abuts against the partial structure of the clamping member 3 exposed in the hollow part 201 to expand it radially, so that the second joint 2 passes through the outer wall of the first joint 1, and abuts against the position of the recessed part 101 of the first joint 1 to fail, and the partial structure of the clamping member 3 exposed in the hollow part 201 is reset and falls into the recessed part 101, completing the connection between the first joint 1 and the second joint 2.

[0054] The present embodiment provides a connection structure between a water outlet pipe seat and a radiator hose, which comprises a first joint 1 connected to a water outlet 120 and a second joint 2 connected to the pipe mouth of the radiator hose, and a movable protrusion 301 disposed on the inner side of the second joint 2 and adapted to move radially along the second joint 2 is connected to a recessed portion 101 on the outer side of the first joint 1. When the second joint 2 is sleeved onto the first joint 1, the movable protrusion 301 is quickly connected to the recessed portion 101, thereby realizing a quick connection between a water outlet 120 of the water outlet pipe seat 100 and the pipe mouth of the radiator hose. This solves the problem that the assembly of the joint of the water outlet pipe and the joint of the radiator hose in the current water outlet pipe seat assembly takes a long time, thereby affecting production efficiency.

The partial structure of the clamping member 3 exposing the hollow portion 201 is reset and falls into the recessed portion 101, thereby achieving a stable connection between the first joint 1 and the second joint 2.

[0061] Furthermore, if Figure 3 As shown, in this embodiment, the clamp 3 exposes two hollow portions 201 at least at two symmetrical positions to facilitate clamping of the recessed portion 101 .

[0062] Furthermore, if Figure 3 As shown, an opening is formed in one direction of the clamp 3, and the circumferential position with a hollow portion 201 on the outer side of the second joint 2 is clamped through the opening, so that part of the structure of the clamp 3 is exposed in the hollow portion 201, thereby forming a movable protrusion 301.
