Description

Technical Field

[0001] This utility model belongs to the field of water pump motor manufacturing, specifically relating to an integrated end cap and motor. Background Technology

[0002] The prior patent CN 207212660 U, entitled "A Novel Pump and Motor Connector Cover", owned by the applicant's controlling parent company, includes a double-sided cover plate (1). One side of the double-sided cover plate (1) is a pump cover surface (2), and the other side is a motor front end cover surface (3). The shaft hole of the pump cover and the shaft hole of the motor front end cover are the same shaft hole. The pump cover surface (2) of the double-sided cover plate (1) has a water outlet hole (4) that connects the pump cover surface (2) and the motor front end cover surface (3). The port of the water outlet hole (4) located on the side of the motor front end cover surface (3) is provided with an extension pipe (5), and the extension pipe (5) and the double-sided cover plate (1) are integrally cast. The water outlet of the extension pipe (5) is located directly below the double-sided cover plate (1), and the water inlet of the extension pipe (5) is provided with a pipe interface (6). The pump cover (2) has a secondary locking platform (7) around its opening, and the motor front cover (3) has a secondary locking platform (8) around its opening. Multiple reinforcing ribs (9) are provided on the inner wall of the motor front cover (3). Its drawback is that this new type of pump-motor cover does not have a condensate drain hole for the motor, causing the condensate to be unable to drain in time during use, thus affecting the motor's service life. Utility Model Content

[0003] Design objective: To avoid the shortcomings of the prior art, this paper designs an integrated end cap and motor that not only facilitates the timely drainage of condensate generated by the motor, but also has a compact structure and good waterproof performance.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The upper end face of the end cover body is provided with a first stop for assembly with the motor housing, and the lower end face of the end cover body is provided with a second stop for assembly with the water pump housing. The upper end face of the end cover body is provided with a through hole for the motor power output shaft, and the through hole for the motor power output shaft passes through both the upper and lower end faces of the end cover body. The upper end face of the end cover body is provided with a motor bearing mounting chamber. A groove is provided on one side of the end cover body. A through hole is provided on the upper end face of the end cover body, and the through hole extends vertically downward and communicates with the groove. The design of the groove being located between the first stop and the motor bearing mounting chamber is one of the technical features of this utility model. The purpose of this design is as follows: the upper end face of the end cover body is provided with a first stop for assembly with the motor housing, and the lower end face of the end cover body is provided with a second stop for assembly with the water pump housing. The upper end face of the end cover body is provided with a through hole for the motor power output shaft, which extends through both the upper and lower end faces of the end cover body. The upper end face of the end cover body is provided with a motor bearing mounting chamber. A groove is provided on one side of the end cover body. The upper end face of the end cover body is provided with a through hole that extends vertically downward and communicates with the groove. The groove is located between the first stop and the motor bearing mounting chamber. The through hole on the upper end face of the end cover body and the groove on one side of the end cover body add a drainage hole to the motor equipped with the integrated end cover (the motor is vertically mounted on the water pump). In this way, the condensate inside the motor can be discharged outward through the through hole and the groove under the action of gravity, thereby extending the service life of the motor.

[0006] 2. The lower end face of the end cover body is provided with a water pump outlet chamber, and the other side of the end cover body is provided with a water outlet. The end cover body has a water outlet channel, with one end of the channel communicating with the water outlet and the other end communicating with the water pump outlet chamber. This design is the second technical feature of this utility model. The purpose of this design is that the lower end face of the end cover body is provided with a water pump outlet chamber, the other side of the end cover body is provided with a water outlet, and the end cover body has a water outlet channel, with one end of the channel communicating with the water outlet and the other end communicating with the water pump outlet chamber. In this way, the motor end cover, the water pump end cover, and the water pump outlet are all concentrated on an integrated end cover. This makes the integrated end cover and the water pump motor structure assembled from the integrated end cover more compact, thereby greatly saving the installation space of the water pump motor.

[0007] 3. The end cap body has an annular water-proof cavity located between the motor bearing mounting chamber and the water pump outlet chamber. The inner side of the annular water-proof cavity communicates with the through hole of the motor power output shaft, and the outer side communicates with the groove. This is the third technical feature of this utility model. The purpose of this design is that the annular water-proof cavity, located between the motor bearing mounting chamber and the water pump outlet chamber, with its inner side communicating with the through hole of the motor power output shaft and its outer side communicating with the groove, allows water seeping from the water pump along the power output shaft to flow out through the annular water-proof cavity and the groove, thereby preventing water seeping from the water pump from entering the motor along the power output shaft, thus improving the waterproof effect of the water pump motor.

[0008] 4. The design of an annular groove for installing a skeleton oil seal on the inner wall of the motor bearing mounting chamber is the fourth technical feature of this utility model. The purpose of this design is that the annular groove on the inner wall of the motor bearing mounting chamber for installing a skeleton oil seal further improves the waterproof effect of the motor.

[0009] 5. The fifth technical feature of this utility model is that a flange is provided in the middle of the end cover body, and the outer diameter of the flange is larger than the diameter of the end cover body. The flange has multiple mounting through holes on its front side that extend through both sides. This design facilitates the fixed installation of the motor assembled from the one-piece end cover.

[0010] 6. The outer circular surface of the end cap body is provided with four first lugs, which are located outside the first stop. The front of the first lug is provided with a first lug through hole, which penetrates both sides of the first lug. The outer circular surface of the end cap body is provided with three second lugs, which are located outside the second stop. The front of the second lug is provided with a second lug through hole, which penetrates both sides of the second lug. The design of the first lugs and the second lugs being located on both sides of the flange is the sixth technical feature of this utility model. The purpose of this design is as follows: four first lugs are provided on the outer circular surface of the end cap body, and the four first lugs are located outside the first stop. The front of the first lug is provided with a first lug through hole, and the first lug through hole penetrates both sides of the first lug. Three second lugs are provided on the outer circular surface of the end cap body, and the three second lugs are located outside the second stop. The front of the second lug is provided with a second lug through hole, and the second lug through hole penetrates both sides of the second lug. The first lugs and second lugs are located on both sides of the flange. The arrangement of the first lugs and the first lug through holes facilitates the fixed installation of the integrated end cap and the motor housing. The arrangement of the second lugs and the second lug through holes facilitates the fixed installation of the integrated end cap and the water pump housing.
