Description

Technical Field

[0001] This utility model relates to the field of electronic water pump technology, specifically an integrated electronic water pump. Background Technology

[0002] Electric water pumps are widely used in the thermal management systems of new energy vehicles. They are key components for transporting coolant and are generally used in air conditioning systems, battery heating or cooling, and motor and electronic control cooling. Typically, an electric water pump consists of key components such as a housing, motor, and controller.

[0003] In the prior art, patent announcement number CN222478967U discloses an integrated electronic water pump, including a housing and a volute connected to the housing. The volute is provided with a sealing module that seals the integrated electronic water pump with a thermal management system integrated module. Along the axial direction of the volute, a first flow port is provided at one end of the volute, and a second flow port communicating with the first flow port is provided on the side of the volute.

[0004] To prevent foreign objects from entering the electronic water pump, a filter screen is typically installed at the pump's inlet. However, with prolonged use, this filter screen gradually becomes clogged. Specifically, when the filter screen becomes clogged due to extended use, the coolant cannot circulate smoothly within the pipes. In this situation, the coolant cannot effectively reach the battery compartment of the new energy vehicle, thus failing to provide the necessary cooling function. Especially during high-speed driving, if the battery loses critical cooling support, it faces the risk of overheating, which may not only affect battery performance and lifespan but also pose a safety hazard, significantly threatening driving safety. Therefore, an integrated electronic water pump is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an integrated electronic water pump to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated electronic water pump, comprising a pump body, a volute fixedly mounted on the pump body, an outlet fixedly mounted at the edge of the volute, an inlet fixedly mounted at the middle of the volute, a filter mechanism connected to the inlet, the filter mechanism including a connection port fixedly mounted on the inlet, a filter screen frame slidably mounted inside the connection port, a fine filter screen fixedly mounted on the filter screen frame, an inner rubber ring fixedly mounted inside the filter screen frame, an outer rubber ring fixedly mounted outside the filter screen frame, and a flow channel assembly mounted inside the connection port.

[0007] Preferably, a spring seat is fixedly installed inside the connection port, a return spring is installed on the spring seat, and a limit ring is installed inside the connection port.

[0008] Preferably, the connection port is provided with threads, and the limiting ring is installed in the connection port by the threads.

[0009] Preferably, the filter frame is confined within the connection port by a limiting ring, the fine filter is installed within the connection port through the filter frame, one end of the return spring is connected to the spring seat, and the other end of the return spring is connected to the bottom of the filter frame. Mounting grooves are provided on both the inner and outer walls of the filter frame, the inner rubber ring is installed on the inner wall of the filter frame through the mounting groove, and the outer rubber ring is installed on the outer wall of the filter frame through the mounting groove.

[0010] Preferably, the flow channel assembly includes a positioning frame fixedly installed in the connection port, an emergency flow channel is fixedly installed on the positioning frame, a flow channel notch is opened at the upper edge of the emergency flow channel, a coarse filter screen is fixedly installed at the lower end of the emergency flow channel, a liquid flow sensor is fixedly installed inside the emergency flow channel, and a data cable is connected to the liquid flow sensor.

[0011] Preferably, the emergency flow channel has an installation port, and the liquid flow sensor is installed on the emergency flow channel through the installation port.

[0012] Preferably, the emergency flow channel is fixedly installed in the connection port by a positioning frame, and a sliding opening is provided in the middle of the filter frame. The filter frame is slidably installed on the emergency flow channel through the sliding opening, and the filter frame stops at the opening of the flow channel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, the return spring applies a pushing force to the filter screen frame, ensuring it fits tightly against the limiting ring, thereby fixing the fine filter screen at the water inlet. The coolant must pass through the fine filter screen before flowing into the volute to prevent impurities from entering the water pump.

[0015] 2. In this application, when the fine filter is completely blocked, the suction force generated by the water pump will cause the filter frame to shift downwards. As the filter frame moves downwards, the flow channel opening opens, allowing coolant to flow into the volute through the emergency flow channel. This mechanism ensures that even in the emergency situation of a blocked fine filter, the coolant can still maintain circulation in the piping system, thereby ensuring the normal heat dissipation function of the vehicle battery and preventing potential dangerous situations.

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an integrated electronic water pump, including a water pump body 1, a volute 2 fixedly installed on the water pump body 1, a water outlet 3 fixedly installed at the edge of the volute 2, a water inlet 4 fixedly installed in the middle of the volute 2, a filter mechanism 5 connected to the water inlet 4, and a flow channel assembly 6 installed in the connection port 501. Through the cooperation of the filter mechanism 5 and the flow channel assembly 6, even if the filter screen is blocked, the coolant can still circulate in the pipe, so that the vehicle battery can dissipate heat normally and avoid dangerous situations.

[0023] like Figure 2 and Figure 3 As shown, the filtration mechanism 5 includes a connection port 501 fixedly installed on the water inlet 4. A filter screen frame 504 is slidably installed inside the connection port 501. A fine filter screen 503 is fixedly installed on the filter screen frame 504. An inner rubber ring 505 is fixedly installed on the inner side of the filter screen frame 504, and an outer rubber ring 506 is fixedly installed on the outer side of the filter screen frame 504. A spring seat 508 is fixedly installed inside the connection port 501. A return spring 507 is installed on the spring seat 508. A limit ring 502 is installed inside the connection port 501. A thread is opened inside the connection port 501. The limit ring 502 is installed inside the connection port 501 through the thread. One end of the return spring 507 is connected to the spring seat 508, and the other end of the return spring 507 is connected to the bottom of the filter screen frame 504.

[0024] Specifically, the return spring 507 continuously applies a stable thrust to the filter frame 504, ensuring that the filter frame 504 is tightly pressed against the position of the limiting ring 502. In this way, the fine filter 503 is securely fixed inside the inlet 4. Before the coolant enters the volute 2, it is filtered through the fine filter 503, a process that effectively intercepts and removes various impurities and particles from the coolant. This prevents these impurities from entering the water pump along with the coolant, thus protecting the water pump from damage and extending its service life.

[0025] like Figure 2 and Figure 4 As shown, the flow channel assembly 6 includes a positioning frame 603 fixedly installed in the connection port 501. An emergency flow channel 601 is fixedly installed on the positioning frame 603. A flow channel notch 602 is opened at the upper edge of the emergency flow channel 601. A coarse filter screen 604 is fixedly installed at the lower end of the emergency flow channel 601. A liquid flow sensor 605 is fixedly installed inside the emergency flow channel 601. A data cable 606 is connected to the liquid flow sensor 605. An installation port is opened on the emergency flow channel 601. The liquid flow sensor 605 is installed on the emergency flow channel 601 through the installation port. A sliding port is opened in the middle of the filter screen frame 504. The filter screen frame 504 is slidably installed on the emergency flow channel 601 through the sliding port, and the filter screen frame 504 stops at the flow channel notch 602.

[0026] Specifically, when the fine filter 503 becomes completely clogged due to impurities, the strong suction generated by the water pump during operation will inevitably exert a downward pull on the filter frame 504, causing it to move downwards. As the filter frame 504 gradually moves downwards, the previously closed flow channel opening 602 will open. Once the flow channel opening 602 successfully opens, the coolant can flow smoothly into the volute 2 through the newly formed emergency flow channel 601. This series of actions ensures that even in an emergency where the fine filter 503 is completely clogged, the coolant can still circulate within the piping system through this emergency channel, thus promptly removing the heat generated by the vehicle battery during operation and ensuring that the battery can maintain a normal temperature range for heat dissipation. In this way, not only is the normal operating condition of the vehicle battery guaranteed, but more importantly, various dangerous situations that may be caused by battery overheating are avoided, greatly improving the safety and reliability of vehicle operation.

[0027] Working principle: During operation, the volute 2 is first connected to the vehicle's circulation pipe. Then, the rotor inside the water pump body 1 drives the impeller inside the volute 2 to rotate, causing coolant to enter the impeller 2 through the inlet 4 and exit through the outlet 3. The return spring 507 provides thrust to the filter frame 504, pressing it against the limiting ring 502, thus fixing the fine filter 503 inside the inlet 4. Before entering the volute 2, the coolant passes through the fine filter 503, filtering the coolant and preventing impurities from entering the water pump. When the fine filter 503 is completely clogged, the suction generated by the water pump will cause the filter frame 504 to move downwards. When the filter frame 504 moves downwards, the flow channel opening 602 will open. After the flow channel opening 602 opens, the coolant will enter the volute 2 through the emergency flow channel 601. This ensures that the coolant can still circulate in the pipes even in the emergency situation of the fine filter 503 being clogged, so that the vehicle battery can dissipate heat normally and avoid dangerous situations. In addition, the liquid flow sensor 605 can detect whether liquid is passing through the emergency flow channel 601. When liquid is passing through the emergency flow channel 601, it means that the fine filter 503 is clogged, thus reminding the user to replace the filter in time.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
