Description

Technical Field

[0001] The invention relates to the technical field of automobile electronic water pumps, in particular to a highly sealed and leak-proof automobile electronic water pump. Background Art

[0002] An automotive electronic water pump is a device used in a vehicle's cooling system that is primarily responsible for circulating coolant to keep the engine at an optimal operating temperature. Unlike traditional mechanical water pumps, electronic water pumps are usually driven by electric motors, which have higher efficiency and controllability. In the prior art, water leakage is easy to occur at the connection position between the electronic water pump and the pipeline. The automobile electronic water pump is prone to leakage due to poor sealing and the connection is not stable enough. In order to overcome the above-mentioned shortcomings, a Chinese patent of the prior art (Announcement No. CN103256242B) discloses an automotive electronic water pump, including a pump housing, a pump head, a housing, a rotor and a stator; the pump head is installed on one end face of the pump housing and forms a pump chamber with the pump housing; the housing is installed on the other end face of the pump housing and forms a closed accommodation chamber with the pump housing; the rotor is located in the aforementioned pump chamber; the stator is fixed in the aforementioned accommodation chamber and surrounds the aforementioned rotor. By sandwiching a static sealing ring between the pump head and the pump housing and forming a static sealing structure, the water channel in the pump chamber is completely isolated from the stator, thereby replacing the design of the traditional dynamic mechanical sealing structure. In this way, on the one hand, the performance loss caused by the friction resistance of the dynamic mechanical seal during operation of the pump can be effectively eliminated, thereby improving the efficiency of the pump. On the other hand, the wear of the mechanical seal can effectively eliminate the shortening of the seal life and the occurrence of water leakage, thereby improving the reliability of the pump. In order to overcome the above-mentioned shortcomings, a Chinese patent of the prior art (Announcement No. CN114320999A) discloses an automotive electronic water pump, in which an annular sleeve and a first elastic snap ring are arranged in a limiting mounting hole, the annular sleeve is arranged in the limiting mounting hole and sleeved on the front part of the shaft, a first annular snap ring groove is arranged on the front peripheral side of the shaft, the first elastic snap ring is clamped in the first annular snap ring groove, the depth of the first annular snap ring groove is less than the outer diameter of the ring body of the first elastic snap ring, the front end of the inner hole of the annular sleeve forms a first tapered hole with an aperture increasing from back to front, the front peripheral side of the shaft is radially inwardly recessed and provided with a step surface, and the inner hole of the annular sleeve is radially protruding inwardly to provide a limiting block; the advantage is that when the shaft moves more backward relative to the annular sleeve, the annular sleeve holds the first elastic snap ring more tightly, the better the clamping effect is, so that the annular sleeve and the shaft are not easily misaligned, and the first elastic snap ring is protected to a certain extent, so that the connection between the impeller and the shaft is tighter; Although the prior art can overcome the above-mentioned deficiencies, there are still other problems in its operation, such as: when the automotive electronic water pump is in use, it is inconvenient to connect it to the pipeline, and when connected, the pipeline is easily blocked for conveying liquid, which is not conducive to the delivery of the automotive electronic water pump.

[0008] Furthermore, the stable anti-blocking mechanism also includes a disc rod installed through the inside of the liquid inlet, and a second bevel gear is fixedly installed on the inner side of the disc rod, and a first bevel gear is meshingly installed on the lower end of the second bevel gear, and a rotating gear is fixedly installed on the inner side of the front and rear two first bevel gears, and the rotating gear is rotatably installed on the inner wall of the liquid inlet through a limit sleeve.

[0009] Furthermore, a toothed plate is meshedly mounted on the lower end of the rotating gear, and the right side of the toothed plate is fixedly mounted on the left end of the limiting rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. A component capable of automatic locking and sealing to prevent leakage is provided. When in use, the pump body adds liquid into the pump body through the liquid inlet and discharges it through the liquid outlet. Before the pump body is used, the liquid inlet and the liquid outlet are both installed with a specific delivery pipe.

[0015] 2. When the movable ring is squeezed and moved to the left, the limit rod passes through the fixed ring and drives the tooth plate to move to the left. As the tooth plate moves to the left, the tooth plate causes the rotating gear meshing with it to rotate, and while squeezing the vibration spring, the lug at the lower end knocks on the liquid inlet, thereby causing the liquid inlet to vibrate, thereby preventing impurities from solidifying and accumulating on the surface of the screen after the pump body was used last time. The impurities on the surface of the screen can be removed by vibration to ensure subsequent liquid delivery; 3. A component for limiting support of the conveying pipeline is arranged on the inner side of the right end of the fixing part. When in use, when the conveying pipeline vibrates and shakes, it is buffered by the supporting arc plate. During buffering, the supporting arc plate transmits force to the buffer rod rotatably installed at the upper end. Under the action of the damping rod, the force of reciprocating vibration of the buffer spring can be avoided, thereby reducing shock and protecting the connection between the conveying pipeline and the liquid inlet to avoid compression bending damage and increase the service life of the device.

In order to solve the problems of inconvenient installation of the water pump and poor sealing effect, the invention discloses: a pump body 1 and a liquid inlet 2 arranged at the right end of the pump body 1, and a liquid outlet 3 is arranged at the upper end of the pump body 1, and a delivery pipe 4 is arranged inside the liquid inlet 2 and the liquid outlet 3, and a screen 18 is arranged inside the liquid inlet 2 and the liquid outlet 3, and a pull rod 5 is installed through the upper and lower ends of the liquid inlet 2, and a highly sealed anti-leakage mechanism is arranged at the lower end of the pull rod 5, and the highly sealed anti-leakage mechanism is provided with a locking block 6, and the outer side of the locking block 6 is fixedly installed on the inner side of the pull rod 5, the highly sealed anti-leakage mechanism also includes a card slot 8 opened on the outer side of the delivery pipe 4, and the card slot 8 corresponds to the position of the locking block 6, and the shape of the locking block 6 is inclined, and a clamping spring 7 is sleeved on the surface of the pull rod 5, and the upper and lower ends of the clamping spring 7 are arranged between the liquid inlet 2 and the locking block 6, and the liquid inlet 2 and the locking block 6 are provided between the upper and lower ends of the clamping spring 7. A fixed ring 9 is fixedly installed on the inner wall of the liquid inlet 2, and a limit rod 11 is installed through the upper and lower ends of the fixed ring 9, and a movable ring 12 is fixedly installed on the right side of the limit rod 11, and a slider 13 is arranged on the upper and lower ends of the movable ring 12, a slide groove 14 is opened on the inner wall of the liquid inlet 2, and the slider 13 is connected to the slide groove 14 in a sliding connection, and a return spring 15 is sleeved on the outer side of the limit rod 11, and the left and right sides of the return spring 15 are arranged between the fixed ring 9 and the movable ring 12, two elastic air bags 10 are arranged on the right side of the fixed ring 9, and the shape of the elastic air bag 10 is arc-shaped, and an air guide tube 16 is installed through the outer side of the elastic air bag 10, and the right side of the air guide tube 16 is connected with a sealing air bag 17, the outer side of the sealing air bag 17 is fixedly installed on the inner wall of the liquid inlet 2, and the shape of the sealing air bag 17 is circular, and the inner side of the sealing air bag 17 fits the surface of the conveying pipe 4; When the pump 1 is in use, the liquid is added into the pump body 1 through the liquid inlet 2 and then discharged through the liquid outlet 3. Before the pump 1 is used, the liquid inlet 2 and the liquid outlet 3 are both installed with the specific delivery pipe 4. When the delivery pipe 4 is installed into the liquid inlet 2, the delivery pipe 4 contacts the locking block 6. Under the inclined setting of the locking block 6, the locking block 6 is pushed upward, and the delivery pipe 4 is continued to be installed until the slot 8 on the delivery pipe 4 corresponds to the position of the locking block 6. Then, through the setting of the locking spring 7, the locking block 6 can be engaged in the slot 8 for fixed installation. On the contrary, when the delivery pipe 4 needs to be removed, the pull rod 5 is pulled so that the pull rod 5 can pull the locking block 6 out of the engagement of the slot 8. Therefore, the effect of convenient installation and disassembly can be achieved, and the pump body 1 and the delivery pipe 4 can be quickly engaged and fixed, which is convenient for the use of the staff and can also save the operation time of the staff. 3 are all provided with screens 18 inside, which can filter the transported liquid, prevent impurities from entering and accumulating inside the pump body 1, prevent the parts inside the pump body 1 from being damaged, and improve the service life of the device. When the delivery pipeline 4 is installed, the left end of the delivery pipeline 4 squeezes the movable ring 12 at the same time. Under the limitation of the slider 13 and the slide groove 14, the movable ring 12 moves to the left to squeeze the elastic airbag 10 on the right side of the fixed ring 9, so that the air inside the elastic airbag 10 is delivered to the sealing airbag 17 through the air guide tube 16. After receiving the air, the sealing airbag 17 expands and fits the surface of the delivery pipeline 4. Conversely, when the delivery pipeline 4 stops squeezing the movable ring 12, the movable ring 12 can be reset under the setting of the limit rod 11 and the reset spring 15, and the air inside the sealing airbag 17 is sucked back into the elastic airbag 10 through the negative pressure of the expansion of the elastic airbag 10, so that the effect of high sealing and leakage prevention can be achieved, the sealing performance between the liquid inlet 2 and the delivery pipeline 4 can be guaranteed, and leakage during liquid transportation can be prevented.

[0020] Embodiment 2: Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8The technical solution shown in the embodiment is based on the first embodiment. In order to solve the problem that impurities inside the water pump are likely to affect the service life of the water pump, the following is disclosed: a knocking bin 26 is fixedly installed on the outer wall of the liquid inlet 2, and a stable anti-blocking mechanism is arranged inside the knocking bin 26, and the stable anti-blocking mechanism is provided with a movable knocking plate 27, and the outer side of the movable knocking plate 27 is in contact with the inner wall of the knocking bin 26, the stable anti-blocking mechanism also includes a disc rod 23 installed through the inside of the liquid inlet 2, and a second bevel gear 22 is fixedly installed on the inner side of the disc rod 23, and the lower end of the second bevel gear 22 is meshed with the first bevel gear 21, and the front and rear first bevel gears 23 and 24 are provided on the inner side of the disc rod 23. A rotating gear 20 is fixedly installed on the inner side of the bevel gear 21, and the rotating gear 20 is rotatably installed on the inner wall of the liquid inlet 2 through a limiting sleeve. A tooth plate 19 is meshedly installed on the lower end of the rotating gear 20, and the right side of the tooth plate 19 is fixedly installed on the left end of the limiting rod 11. A positioning bolt 24 is fixedly installed on the upper end surface of the disc rod 23, and a groove push rod 25 is sleeved on the surface of the positioning bolt 24, and a knocking bin 26 is installed through the left side of the groove push rod 25, and the lower end of the movable knocking plate 27 is connected to the liquid inlet 2 through a vibration spring 28, and an inclined block 29 is fixedly installed on the outer side of the movable knocking plate 27, and the inclined block 29 is correspondingly arranged with the groove push rod 25; When the movable ring 12 is squeezed and moved to the left, the limiting rod 11 passes through the fixed ring 9 and drives the toothed plate 19 to move to the left. As the toothed plate 19 moves to the left, the toothed plate 19 causes the rotating gear 20 meshing therewith to rotate. The rotation of the rotating gear 20 can drive the disc rod 23 to rotate through the meshing of the first bevel gear 21 and the second bevel gear 22. When the disc rod 23 rotates, the positioning bolt 24 on the surface thereof can move the groove push rod 25. The groove push rod 25 is moved left and right under the limit of the knocking bin 26. When the groove push rod 25 moves to the left, the inclined block 29 is squeezed. After the inclined block 29 contacts the groove push rod 25, the inclined block 29 pushes the movable knocking plate 27 downward due to its own inclination. When the movable knocking plate 27 is pressed down, it squeezes the vibration spring 28 and knocks the liquid inlet 2 through the convex block at the lower end, so that the liquid inlet 2 vibrates, avoiding impurities solidified and accumulated on the surface of the screen 18 after the pump body 1 was used last time. The impurities on the surface of the screen 18 can be vibrated and removed to ensure the subsequent liquid transportation.

[0021] Embodiment 3: Figure 2 , Figure 3 , Fig. 9 and Fig.10The technical solution shown is based on the second embodiment. In order to solve the problem that the connection between the water pump and the pipeline is easily damaged, it is disclosed that: the upper and lower ends of the liquid inlet 2 are fixedly installed with fixing parts 30, and the inner side of the right end of the fixing part 30 is provided with a support anti-deviation mechanism, and the support anti-deviation mechanism is provided with a support arc plate 32, and the lower end of the support arc plate 32 corresponds to the outer wall of the conveying pipeline 4, and the support anti-deviation mechanism also includes a damping rod 31 fixedly installed at the lower end of the fixing part 30, and the lower end of the damping rod 31 is fixedly installed on the support arc plate The upper end of the arc plate 32 is supported by the arc plate 32, and the lower end of the arc plate 32 is in an arc shape, and the lower end of the arc plate 32 is provided with an anti-slip pad 33, the lower end of the fixing member 30 is fixedly installed with a positioning rod 34, and a moving block 35 is installed through the surface of the positioning rod 34, and a buffer rod 36 is rotatably installed at the lower end of the moving block 35, and the lower end of the buffer rod 36 is rotatably installed on the upper end of the arc plate 32, and a buffer spring 37 is sleeved on the surface of the positioning rod 34, and the left and right sides of the buffer spring 37 are arranged between the fixing member 30 and the moving block 35; A component for limiting and supporting the conveying pipe 4 is provided on the inner side of the right end of the fixing member 30. During use, when the conveying pipe 4 vibrates and shakes, it is buffered by the supporting arc plate 32. During buffering, the supporting arc plate 32 transmits force to the buffer rod 36 rotatably installed at the upper end. The buffer rod 36 rotates and pushes the moving block 35 along the positioning rod 34. The moving block 35 is pushed along the positioning rod 34 to squeeze the buffer spring 37, so that the elastic force of the buffer spring 37 itself is used for buffering to avoid the conveying pipe 4 from being damaged by excessive pressure. At the same time, the anti-slip pad 33 is provided to increase the friction between the supporting arc plate 32 and the conveying pipe 4 to avoid deviation. Finally, under the action of the damping rod 31, the force of the buffer spring 37 to vibrate back and forth can be avoided, so as to reduce shock and protect the connection between the conveying pipe 4 and the liquid inlet 2 to avoid compression and bending damage, thereby increasing the service life of the device.
