[0001] This utility model relates to the technical field of automotive engine water pumps, specifically an integrated automotive engine water pump. Background Technology

[0002] A car water pump is a machine that transfers the mechanical energy of the engine to the fluid, increasing its kinetic and pressure energy. It is an important component of the engine cooling system.

[0003] For example, an integrated automotive engine water pump with authorization announcement number "CN219242306U" solves the problem of existing integrated automotive engine water pumps occupying a large space and causing significant space and material waste. The above-mentioned water pump is assembled into an automotive engine water pump and air pump bracket assembly by combining the engine air pump bracket with the water pump body and air pump bracket in one piece casting and one-stop processing, which ensures casting strength and processing accuracy, and also greatly saves its assembly space on the engine. Considering that the existing integrated automotive engine water pumps have shaft bearings installed between the water pump and the shaft during rotation, the vibration during movement generates noise, which can damage the pump itself and affect its service life. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing integrated automotive engine water pumps generate noise due to vibration during operation, which causes damage to the pump itself and affects its service life. Therefore, this invention proposes an integrated automotive engine water pump.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated automotive engine water pump, comprising a pump body and connecting holes, wherein the surface of the pump body is machined with multiple connecting holes, the lower end of the pump body is fixedly connected to a rubber strip, the upper end of the pump body is fixedly connected to a water inlet head and a water outlet head, and the inner wall of the pump body is connected to a disassembly mechanism.

[0006] Preferably, the disassembly mechanism includes a connecting plate, the outside of which is threaded to the pump body, the upper end of which is fixedly connected to a connecting cylinder, and the inner wall of the connecting cylinder abutting against the water seal.

[0007] Preferably, the inner wall of the water seal is movably connected to the shaft bearing, and the outer wall of the shaft bearing is connected to a noise reduction mechanism.

[0008] Preferably, the noise reduction mechanism includes a rubber sleeve, the inner wall of which is fixedly connected to a shaft bearing, the outer wall of which is threadedly connected to a hammer-shaped cylinder, and the inner wall of the hammer-shaped cylinder is machined with a through hole.

[0010] Preferably, the outer wall of the connecting disc is fitted with the sealing ring, and the upper end of the sealing ring is fixedly connected to the pump body.

[0011] The integrated automotive engine water pump proposed in this utility model has the following advantages: the impeller is driven to rotate by the shaft bearing, and the movement of the impeller helps the coolant to circulate in the pump body. The vibration generated by the rotation of the shaft bearing is absorbed by the rubber sleeve on the conical cylinder and further absorbed by the multi-position through holes on the conical cylinder, thereby reducing the damage caused by the movement between the shaft bearing and the pump body and improving the service life.

[0019] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0020] Please see Figure 1-6 In this embodiment, an integrated automotive engine water pump includes a pump body 1 and connecting holes 2. The surface of the pump body 1 is machined with multiple connecting holes 2. The lower end of the pump body 1 is fixedly connected to a rubber strip 3, and the upper end of the pump body 1 is fixedly connected to a water inlet head 4 and a water outlet head 5. A disassembly mechanism 6 is connected to the inner wall of the pump body 1.

[0021] The disassembly mechanism 6 includes a connecting plate 601, which can be unscrewed from the pump body 1 to separate the shaft bearing 7 and the rubber sleeve 801 inside the pump body 1. The outside of the connecting plate 601 is threaded to the pump body 1, and the upper end of the connecting plate 601 is fixedly connected to the connecting cylinder 602. The inner wall of the connecting cylinder 602 is pressed against the water seal 603.

[0022] The inner wall of the water seal 603 is movably connected to the shaft bearing 7. The outer wall of the shaft bearing 7 is connected to a noise reduction mechanism 8. The vibration generated by the rotation of the shaft bearing 7 during movement is absorbed by the rubber sleeve 801 on the conical cylinder 802, thereby achieving the effect of noise reduction for the movement of the shaft bearing 7. The noise reduction mechanism 8 includes a rubber sleeve 801. The inner wall of the rubber sleeve 801 is fixedly connected to the shaft bearing 7, and the outer wall of the rubber sleeve 801 is threadedly connected to the hammer-shaped cylinder 802. The inner wall of the hammer-shaped cylinder 802 is machined with a through hole 803.

[0023] The shaft bearing 7 drives the impeller 10 to rotate. The movement of the impeller 10 helps the coolant to circulate in the pump body 1. The vibration generated by the rotation of the shaft bearing 7 is absorbed by the rubber sleeve 801 on the conical cylinder 802 and further absorbed by the multi-position through holes 803 on the conical cylinder 802. This reduces the damage caused by the movement between the shaft bearing 7 and the pump body 1 and improves its service life.

[0024] A hub 9 is installed at the end of the shaft bearing 7, and an impeller 10 is installed at the lower end of the shaft bearing 7. The outer wall of the connecting plate 601 is in contact with the sealing ring 11, and the upper end of the sealing ring 11 is fixedly connected to the pump body 1.

[0025] Working principle:

[0026] The engine air pump bracket is integrated into the pump body 1 to form an integrated assembly. The pump body 1 and the air pump bracket are integrally cast and processed in one stop, ensuring casting strength and machining accuracy. Tightening the connecting plate 601 allows it to be installed inside the pump body 1, enabling the shaft bearing 7 and rubber sleeve 801 to be installed inside the pump body 1. The air pump bracket is assembled through the connecting hole 2 and the lower rubber strip 3, which meets the requirements of the compact layout of the engine and improves installation efficiency. When the hub 9 is driven by external power, the hub 9 will drive the shaft bearing 7 to rotate, which in turn drives the impeller 10 to rotate. Coolant is injected into the interior through the water inlet 4 and flows outward through the drain head 5. The movement of the impeller 10 will help the coolant to form a circulation state. The vibration generated by the rotation of the shaft bearing 7 will be absorbed by the rubber sleeve 801 on the conical cylinder 802 and further absorbed by the multi-position through holes 803 on the conical cylinder 802, thus improving the service life of the shaft bearing 7 inside the pump body 1.

[0027] 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.
