Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to an exhaust device for an automobile electronic water pump. Background Art

[0002] With the popularization of automobiles, for safety and energy-saving considerations, electronic water pumps, as an important part of the automobile cooling system, play a particularly important role. Whether there is air is also a key issue in the quality inspection of whether the electronic water pump is qualified.

[0003] In order to prevent air from being present in the pipeline, existing automotive electronic water pumps usually add liquid through a vacuum device to prevent air from being present in the pipeline.

[0004] Regarding the related technologies mentioned above, although air can be excluded, when the antifreeze is missing, gas will enter the pipeline and the electronic water pump will report an idling failure. It is difficult for individuals or repair shops to exhaust the air in the pipeline, so an exhaust device is needed to solve this problem. Therefore, the technicians in this field provide an exhaust device for an automotive electronic water pump to solve the problems raised in the above background. Utility Model Content

[0005] The purpose of the utility model is to provide an exhaust device for an automobile electronic water pump to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] An exhaust device for an automotive electronic water pump comprises a water pump housing assembly, a rotor gasket, a rotor assembly, a stator assembly, an electric control board assembly, a rear cover, a mounting frame and a motor shaft. The water pump housing assembly and the rotor gasket are fastened together, the rotor assembly is located inside the stator assembly, the stator assembly and the water pump housing assembly are fastened together, the electric control board assembly and the stator assembly are fastened together, the rear cover and the stator assembly are fastened together, the mounting frame and the stator assembly are fastened together, the stator assembly comprises a coil assembly and a stator housing, the water pump housing assembly and the stator housing form a first chamber, the motor shaft is located inside the rotor assembly, the motor shaft and the rotor gasket are fastened together, the motor shaft and the rotor assembly are rotationally connected, the stator housing and the rear cover form a second chamber, and the electric control board assembly is assembled in the second chamber.

[0008] By adopting the above technical scheme, the sealing performance inside the water pump is ensured through the water pump housing assembly and the rotor gasket to prevent liquid leakage, and the power of the water pump is provided by the rotor assembly. The rotor assembly is usually composed of an upper impeller, a rotor core, a magnetic steel, a lower impeller, etc. A stable support structure is provided through the connection between the stator assembly and the water pump housing assembly to ensure the positioning of the motor shaft. The external signal is received by the electric control board assembly and converted into an electrical signal to control the flow rate, speed, time, etc. of the water pump. The motor is protected from interference by the external environment by the back cover. The mounting frame is optimized to achieve stability and support performance while ensuring that the device can be installed in an appropriate position. Axial rotation occurs through the motor shaft and the coil assembly, and a magnetic field is generated at the same time. The first chamber is a wet chamber for placing antifreeze, and the second chamber is a dry chamber with an electric control board assembly to ensure dryness.

[0009] Furthermore, the water pump casing assembly includes a water pump casing body, a rubber pad and a plug. The water pump casing body and the rubber pad are fastened together, the plug and the water pump casing body are threadedly connected, and the water pump casing body is provided with a water inlet, a water outlet and an exhaust port. The water inlet and the water outlet are connected, and the exhaust port and the plug are threadedly connected.

[0010] By adopting the above technical solution, the water pump casing body serves as the main structure of the water pump, which provides a shell for fixing and protecting the internal components. The rubber pad is located between the water pump casing body and other components. The main function of the rubber pad is to provide sealing to prevent water leakage. It can also absorb certain vibrations and reduce noise. The plug is connected to the water pump casing body through threads. The design of the plug allows the user to manually open or close the exhaust port to remove the air in the water pump system to ensure the efficient operation of the water pump. The water inlet and the water outlet are the basic functional parts of the water pump, which are responsible for sucking in and pressing out water respectively. Water can pass through the water pump smoothly to achieve continuous flow. The exhaust port is connected to the plug through threads. The exhaust port removes the internal air before the water pump starts working or if necessary during work to prevent air blockage from affecting the efficiency of the water pump.

[0011] Furthermore, the rubber pad plays a sealing role after being compressed.

[0012] By adopting the above technical solution, the rubber gasket will be compressed when assembled to the water pump housing body. The deformation caused by this compression allows the rubber gasket to fill all possible gaps, thereby forming a continuous sealing interface. This design effectively prevents water and air leakage.

[0013] Furthermore, the rotor gasket is fastened to the top end of the motor shaft.

[0014] By adopting the above technical solution, the rotor assembly will move forward during operation, and the rotor gasket will limit the movement of the rotor assembly. At the same time, the rotor gasket will rub against the end face of the rotor assembly, preventing the rotor assembly from rubbing against the water pump housing, thereby reducing noise.

[0015] Furthermore, the stator assembly also includes a positioning boss, the positioning boss is provided with a positioning surface and a positioning column, the electric control board assembly is provided with a positioning hole and a pin hole, and the electric control board assembly is placed in the positioning column through the positioning hole.

[0016] By adopting the above technical solution, the positioning boss on the stator assembly is used to accurately position the electric control board assembly. This boss provides a fixed reference point to ensure that the electric control board assembly can be installed on the stator assembly in a correct posture and position. The positioning surface and positioning column on the positioning boss are key features in the assembly process. The positioning surface provides a stable support surface for the electric control board assembly, and the positioning column is accurately inserted into the positioning hole on the electric control board assembly to ensure the correct position of the electric control board. The positioning hole is used to receive the positioning column to ensure the correct positioning and alignment of the electric control board assembly on the stator assembly. The pin hole is for receiving the electrical connection pins or wires on the electric control board. These pin holes must be accurately aligned with the corresponding electrical contacts on the stator assembly to ensure the correctness of the electrical connection, thereby improving assembly efficiency, reducing production costs, and helping to ensure product quality and reliability.

[0017] Furthermore, a rotation-stopping groove is provided on the stator shell, and the mounting frame includes a rotation-stopping boss, and the rotation-stopping boss and the rotation-stopping groove are installed correspondingly.

[0018] By adopting the above technical solution, when installing the stator assembly on the mounting frame, it is necessary to first align the anti-rotation groove and the anti-rotation boss, and then gently press down or slide the stator assembly so that the anti-rotation boss can be smoothly embedded in the groove. Once the boss is completely embedded in the groove, the relative position between the stator assembly and the mounting frame is fixed, preventing any unnecessary rotation or sliding, thereby reducing the risk of loosening of components due to vibration or long-term wear, and facilitating the disassembly and replacement of accessories.

[0019] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0020] 1. The water pump casing is the main structure of the water pump. It provides a shell to fix and protect the internal components. The rubber pad is located between the water pump casing and other components. The main function of the rubber pad is to provide sealing to prevent water leakage. It can also absorb certain vibrations and reduce noise. The plug is connected to the water pump casing through threads. The design of the plug allows the user to manually open or close the exhaust port to remove the air in the water pump system and ensure the efficient operation of the water pump. The water inlet and outlet are the basic functional parts of the water pump, which are responsible for sucking in and pressing out water respectively. Water can pass through the water pump smoothly to achieve continuous flow. The exhaust port is connected to the plug through threads. The exhaust port removes the internal air before the water pump starts working or if necessary during work to prevent air blockage from affecting the efficiency of the water pump.

[0021] 2. The rotor gasket is used to limit the movement of the rotor assembly. At the same time, the rotor gasket is allowed to rub against the end surface of the rotor assembly, preventing the rotor assembly from rubbing against the water pump housing, thereby reducing noise.

[0022] 3. When installing the stator assembly on the mounting frame, you first need to align the anti-rotation groove and the anti-rotation boss, and then gently press down or slide the stator assembly to allow the anti-rotation boss to smoothly embed into the groove.
