Description

Technical Field

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

[0002] like Figure 1 and Figure 2 As shown, the first mounting groove 7 on the existing oil pump body 1 for installing the sealing ring is far from the upper surface of the mounting base 2. Therefore, when the oil pump body and the mounting base are assembled, a potential water storage and dust collection space 3 will be formed between the oil pump body and the mounting base. At the same time, when the sealing ring is installed in the first mounting groove 7 and the second mounting groove 8, the two sealing rings will increase the disassembly and assembly resistance of the oil pump body 1 when the oil pump body 1 and the mounting base 2 are disassembled or installed. Utility Model Content

[0003] The purpose of this invention is to provide an electrically driven electronic oil pump to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an electrically driven electronic oil pump, comprising a mounting base and an oil pump body mounted on the mounting base, wherein the oil pump body is provided with a first mounting groove for mounting a sealing ring; after the oil pump body is connected to the mounting base, the upper bottom surface of the first mounting groove is flush with the upper surface of the mounting base.

[0005] As a preferred technical solution of this utility model: the oil pump body is also provided with a second mounting groove for installing the sealing ring, and the second mounting groove is located below the first mounting groove.

[0006] As a preferred technical solution of this utility model, a fixing lug is also provided on the outer circumferential surface of the oil pump body.

[0007] As a preferred technical solution of this utility model: the first mounting groove further includes a groove bottom surface and an inclined surface, and the end of the inclined surface away from the groove bottom surface is inclined downward.

[0008] As a preferred technical solution of this utility model: the angle between the bottom surface of the groove and the inclined surface is an obtuse angle.

[0009] As a preferred technical solution of this utility model, the included angle between the bottom surface of the groove and the inclined surface is 120°.

[0010] As a preferred technical solution of this utility model: the side of the mounting base facing the oil pump body is also provided with a guide surface.

[0011] As a preferred technical solution of this utility model, the guide surface and the outer wall surface of the mounting base are smoothly transitioned by a rounded corner.

[0012] The beneficial effects of this utility model using the above technical solution are as follows: After the oil pump body is connected to the mounting base, the upper bottom surface of the first mounting groove is flush with the upper surface of the mounting base. Therefore, the sealing ring in the first mounting groove can be used to seal from the upper side of the mounting base to reduce the potential water and dust collection space. Thus, while ensuring a reliable seal, the pressing resistance and pulling resistance of the oil pump body can be reduced, facilitating the assembly and disassembly of the oil pump body. In particular, although the device has a simple structure, this simple structure ensures a seal without affecting the overall structure of the oil pump body. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0021] Please see Figure 3-6 An embodiment of this utility model provides an electrically driven electronic oil pump, including a mounting base 2 and an oil pump body 1 mounted on the mounting base 2, wherein the oil pump body 1 is provided with a first mounting groove 7 for mounting a sealing ring; after the oil pump body 1 is connected to the mounting base 2, the upper bottom surface 5 of the first mounting groove 7 is flush with the upper surface of the mounting base 2.

[0022] In summary, after the oil pump body 1 is connected to the mounting base 2, the upper bottom surface 5 of the first mounting groove 7 is flush with the upper surface of the mounting base 2. Therefore, the sealing ring in the first mounting groove 7 can be used to seal from the upper side of the mounting base 2 to reduce the potential water and dust collection space 3. Thus, while ensuring a reliable seal, the pressing resistance and pulling resistance of the oil pump body 1 can be reduced, facilitating the assembly and disassembly of the oil pump body 1. In particular, although the device has a simple structure, this simple structure ensures a seal without affecting the overall structure of the oil pump body 1.

[0023] Furthermore, since the oil pump body 1 is also provided with a second mounting groove 8 for installing the sealing ring, and the second mounting groove 8 is located below the first mounting groove 7, there is a large space between the first mounting groove 7 and the second mounting groove 8. This facilitates the addition of a new sealing ring mounting groove between the first mounting groove 7 and the second mounting groove 8 to meet the customer's requirement to add a third dustproof and waterproof sealing ring.

[0024] Furthermore, since the outer circumferential surface of the oil pump body 1 is also provided with a fixing lug 9, the oil pump body 1 can be fixed to the mounting base 2 by using fasteners such as bolts through the fixing lug 9.

[0025] Based on the above solution, in order to reduce the installation resistance of the oil pump body 1, the following optimizations are made to the oil pump body: the first mounting groove 7 further includes a groove bottom surface 6 and an inclined surface 4, and the end of the inclined surface 4 away from the groove bottom surface 6 slopes downward. Therefore, the setting of the inclined surface 4 allows the sealing ring to move within the first mounting groove 7 during the installation process, thereby avoiding damage to the sealing ring caused by the oil pump body 1 and the mounting base 2 during installation.

[0026] Furthermore, the angle between the bottom surface 6 of the groove and the inclined surface 4 is an obtuse angle; specifically, the angle between the bottom surface 6 of the groove and the inclined surface 4 is 120°. Based on this, the sealing ring can be moved up and down along the inclined surface to reduce the resistance generated by the sealing ring during the disassembly and assembly of the oil pump body 1. Specifically, when the oil pump body 1 is being installed, the sealing ring can be moved from bottom to top to reduce the resistance during the installation of the oil pump body 1. At the same time, when the oil pump body 1 is pulled out upwards, the sealing ring can be moved downwards along the inclined surface 4 to reduce the resistance during the pulling out of the oil pump body 1.

[0027] To reduce the installation resistance of the oil pump body 1, the mounting base 2 is optimized as follows: a guide surface 10 is provided on the side of the mounting base 2 facing the oil pump body 1. Based on this, the guide surface 10 facilitates the smooth entry of the sealing ring into the mounting base 2 while further reducing the resistance of the oil pump body 1 during installation.

[0028] Furthermore, the guide surface 10 and the outer wall surface 11 of the mounting base 2 are smoothly transitioned by rounded corners. Since the guide surface 10 and the outer wall surface 11 of the mounting base are also smoothly transitioned by rounded corners, it ensures that the sealing ring can smoothly enter the outer wall surface 11 from the guide surface 10, while reducing the problem of the sealing ring being scratched by the sharp corners between the outer wall surface 11 and the guide surface 10 during the process of entering the outer wall surface 11.

[0029] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
