Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water pump integrated with a rubber gasket. Background Art

[0002] At present, new energy vehicles are the main development direction of the automotive industry. Since the engine is removed in new energy vehicles, the noise and vibration of the whole vehicle are very small. Most new energy vehicles are equipped with a thermal management integration module. The water pump is the main excitation source on the integration module. Reducing the noise and vibration of the water pump can effectively reduce the noise of the whole vehicle.

[0003] Existing water pumps, such as the prior art with the application number CN201822164269.X, include a water pump impeller, a chassis, a through hole, a column platform, a reinforcing ring, a surface A, blades, reinforcing ribs, a surface B, a first water retaining ring, etc. A reinforcing ring is provided on the circumferential side of the column platform. The cross-section of the reinforcing ring is triangular. By setting the reinforcing ring on the circumferential side of the column platform, the structural strength of the circumferential side of the column platform is improved according to the stability characteristic of a triangle.

[0004] The main function of the water pump on the thermal integration module is to transport liquid. However, during the operation of the prior art, due to reasons such as the difference between the front and rear covers and the liquid reaction force, the impeller will generate an axial force, resulting in the impeller constantly hitting the limit on the volute, generating vibration. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a water pump integrated with a rubber gasket, which can reduce the vibration and noise of the water pump body, has a simple structure, is convenient to install, and has a low cost.

[0006] A water pump integrated with a rubber gasket of the utility model includes a housing mechanism and a conveying mechanism; it also includes a first gasket and a second gasket. The first gasket and the second gasket are both installed on the conveying mechanism. The first gasket and the second gasket are located inside the housing mechanism. The housing mechanism protects the whole, and the conveying mechanism transports water. The first gasket improves the wear resistance of the whole. The second gasket can improve the noise and vibration generated by the axial force during the operation of the whole; the housing mechanism protects the whole and is convenient for assembly. The conveying mechanism transports water. The first gasket improves the wear resistance of the whole, can buffer and reduce vibration, and reduce noise. The second gasket can improve the noise and vibration generated by the axial force during the operation of the whole. The structure is simple. The second gasket is convenient to install and has a low cost.

[0007] Preferably, the housing mechanism includes a volute and a casing. The volute and the casing are connected together by ultrasonic welding; the internal conveying mechanism is protected by the volute and the casing, and it is convenient to assemble the conveying mechanism.

[0008] Preferably, the conveying mechanism includes an upper impeller cover, a lower impeller cover, a waterproof chamber, a stator, a PIN, and a PCB. The PCB is installed on the housing, the PIN is installed on the PCB, the stator is located on top of the PIN, the waterproof chamber is installed on the stator, the lower impeller cover is installed on the waterproof chamber, and the upper impeller cover is installed on the lower impeller cover. Moreover, the conveying mechanism is located inside the volute and the housing. The upper impeller cover and the lower impeller cover are mainly used to fix and protect the impeller, ensuring that the impeller remains stable during high-speed rotation and preventing coolant leakage. During the high-speed rotation of the impeller, the upper impeller cover and the lower impeller cover play a role in sealing and support, ensuring that the coolant circulates inside the impeller without leaking. The waterproof chamber is tightly connected to components such as the impeller and the stator, forming a closed coolant circulation space. During the operation of the water pump, the waterproof chamber ensures that the coolant only circulates inside the water pump and does not penetrate into other areas that should not come into contact with the coolant. When the power is connected to the circuit on the PCB through the PIN, the control logic on the PCB energizes the coil in the stator. After the stator coil is energized, a rotating magnetic field is generated, and this magnetic field interacts with the permanent magnet or induction coil in the rotor to drive the rotor and the impeller to rotate.

[0009] Preferably, a first gasket and a second gasket are added between the volute and the lower impeller cover. Through the above setting, the noise and vibration of the water pump body are improved.

[0010] Preferably, the material of the first gasket is ceramic. Through the above setting, the overall wear resistance is improved, and it can buffer and dampen vibrations and reduce noise.

[0011] Preferably, the material of the second gasket is rubber. When the water pump is running, due to reasons such as the difference between the front and rear covers and the reaction force of the liquid, the impeller will generate an axial force. The impeller will first impact on the first gasket and then be transmitted to the volute through the first gasket. Since the material of the first gasket is rubber and has a vibration absorption effect, the force transmitted to the volute will be weakened, thereby improving the noise and vibration of the water pump body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The overall structure is protected by the housing mechanism and is convenient for assembly. The conveying mechanism transports water. The first gasket improves the overall wear resistance, can buffer and dampen vibrations, and reduce noise. The second gasket can improve the noise and vibration generated by the axial force during the overall operation. The structure is simple, the installation of the second gasket is convenient, and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The upper impeller cover 4 and the lower impeller cover 5 are mainly used to fix and protect the impeller, ensuring that the impeller remains stable during high-speed rotation and preventing coolant leakage. During the high-speed rotation of the impeller, the upper impeller cover 4 and the lower impeller cover 5 play a role in sealing and support, ensuring that the coolant circulates inside the impeller without leakage. The waterproof chamber 6 is tightly connected to components such as the impeller and the stator 7 to form a closed coolant circulation space. During the operation of the water pump, the waterproof chamber 6 ensures that the coolant only circulates inside the water pump and does not penetrate into other areas that should not come into contact with the coolant. When the power supply is connected to the circuit on the PCB 9 through the PIN 8, the control logic on the PCB 9 energizes the coil in the stator 7. After the stator 7 coil is energized, a rotating magnetic field is generated, and this magnetic field interacts with the permanent magnet or induction coil in the rotor to drive the rotation of the rotor and the impeller.

[0026] Embodiment 2

[0027] As Figures 1 to 5 shown, a water pump with an integrated rubber gasket includes a housing mechanism 01 and a conveying mechanism 02, and also includes a first gasket 2 and a second gasket 3. The first gasket 2 and the second gasket 3 are both installed on the conveying mechanism 02, and the first gasket 2 and the second gasket 3 are located inside the housing mechanism 01;

[0033] The material of the second gasket 3 is rubber;

[0034] The overall wear resistance is improved by the first gasket 2, and it can buffer and dampen vibrations and reduce noise. When the water pump is running, due to reasons such as the difference between the front and rear covers and the reaction force of the liquid, the impeller will generate an axial force. The impeller will first impact on the first gasket 2 and then be transmitted to the volute 1 through the first gasket 2. Since the material of the first gasket 2 is rubber and has a vibration-absorbing effect, the force transmitted to the volute 1 will be weakened, thereby improving the noise and vibration of the water pump body.

[0035] As Figures 1 to 5 shown, for a water pump with an integrated rubber gasket of the present utility model, during operation, the upper impeller cover 4 and the lower impeller cover 5 are mainly used to fix and protect the impeller, ensuring that the impeller remains stable during high-speed rotation and preventing coolant leakage. During the high-speed rotation of the impeller, the upper impeller cover 4 and the lower impeller cover 5 play a sealing and supporting role, ensuring that the coolant circulates inside the impeller without leaking outside. The waterproof chamber 6 is tightly connected to components such as the impeller and the stator 7 to form a closed coolant circulation space. During the operation of the water pump, the waterproof chamber 6 ensures that the coolant only circulates inside the water pump and does not penetrate into other areas that should not come into contact with the coolant. When the power supply is connected to the circuit on the PCB 9 through the PIN 8, the control logic on the PCB 9 energizes the coil in the stator 7. After the stator 7 coil is energized, a rotating magnetic field is generated. This magnetic field interacts with the permanent magnet or induction coil in the rotor to drive the rotor and the impeller to rotate. The overall wear resistance is improved by the first gasket 2, and it can buffer and dampen vibrations and reduce noise. When the water pump is running, due to reasons such as the difference between the front and rear covers and the reaction force of the liquid, the impeller will generate an axial force. The impeller will first impact on the first gasket 2 and then be transmitted to the volute 1 through the first gasket 2. Since the material of the first gasket 2 is rubber and has a vibration-absorbing effect, the force transmitted to the volute 1 will be weakened, thereby improving the noise and vibration of the water pump body.

[0036] The stator 7, PIN 8, and PCB 9 of the present utility model are purchased on the market. Those skilled in the art only need to install and operate them according to the attached user manual, without the need for those skilled in the art to perform creative labor.
