Improved electronic oil pump and method of use thereof

Abstract

This invention discloses an improved electronic oil pump, comprising: an oil pump body; a protective plate fixedly connected to the bottom of the oil pump body, and a connecting mechanism fixedly connected to the bottom of the protective plate; a heat dissipation assembly fixedly connected to the right side of the oil pump body; and a buffer mechanism fixedly connected to the left side of the oil pump body. Through the connection mechanism, this invention enables a rearward-pushing turntable to move a rotating rod backward, causing a magnetic coupling disk to contact a bolt for magnetic connection. Then, rotating the turntable causes the rotating rod to rotate, which in turn causes the magnetic coupling disk and bolt to rotate synchronously. The bolt is then tightened for installation. Finally, pulling the rotating rod forward causes the magnetic coupling disk to disengage from the bolt, releasing the magnetic connection. The rotating rod is then rotated counterclockwise, and the rotating rod, in conjunction with a threaded sleeve, tightens and secures the bolt, reducing the impact of accidental operation of the rotating rod on the bolt caused by the magnetic coupling disk.

Description

Technical Field

[0001] This invention relates to the field of electronic oil pump technology, specifically to an improved electronic oil pump and its usage method. Background Technology

[0002] The electronic fuel pump is a roller-type electric gasoline pump, mainly composed of a housing, cylindrical rollers, and a rotor. Five rollers slide radially within the grooves of the rotor. There is a certain eccentricity between the rotor and the housing. Driven by a DC motor, the rotor rotates, and under centrifugal force, the rollers press tightly against the inner surface of the pump body, forming five relatively independent sealed cavities. In a comparative case (publication number CN105179909A), this invention provides an improved fuel pump body, belonging to the field of mechanical technology. This improved fuel pump body includes a main body composed of an integrated chassis and a support. Several independent oil passages of varying widths are opened within the main body. The oil inlets of the oil passages are located on the support, and the oil outlets are located on the chassis. This improved fuel pump body has the advantages of reasonable oil passage distribution, good sealing performance, and stable operation.

[0003] However, during the implementation of the relevant technology, the following problems were found in the improved oil pump body: the body has several oil passages of different widths and independent of each other. The oil inlet of the oil passage is located on the stand, and the oil outlet of the oil passage is located on the chassis. The motor part of the existing electric oil pump includes a permanent magnet fixed on the housing, an armature that generates electromagnetic torque, and a brush device mounted on the housing. The brushes are in contact with the commutator on the armature, and their leads are connected to the terminals on the housing to lead the voltage controlling the electric fuel pump to the armature winding. The two ends of the electric fuel pump housing are rolled and riveted to assemble the components into a non-removable assembly. Its installation requires special tools, which is time-consuming and labor-intensive, reducing the convenience of electric oil pump installation.

[0004] Therefore, it is necessary to redesign the electric fuel pump to effectively prevent the electric motor part of the electric fuel pump, which includes a permanent magnet fixed on the housing, an armature that generates electromagnetic torque, and a brush assembly mounted on the housing. The brushes are in contact with the commutator on the armature, and their leads are connected to the terminals on the housing to lead the voltage controlling the electric fuel pump to the armature winding. The two ends of the electric fuel pump housing are rolled and riveted to assemble the components into a non-removable assembly. Its installation requires special tools and is time-consuming and labor-intensive. Summary of the Invention

The brushes are in contact with the commutator on the armature, and their leads are connected to terminals on the housing to supply the voltage controlling the electric fuel pump to the armature winding. The housing of the electric fuel pump is crimped and riveted at both ends, assembling all components into a non-removable assembly.

[0007] The buffer mechanism includes a fixed plate, a scissor bar, an aluminum plate, and a chain. The fixed plate is fixedly connected to the left side of the oil pump body.

[0014] As a preferred embodiment of the present invention, magnetic blocks are fixedly connected to both the back end of the magnetic coupling disk and the front end of the bolt, and the number of magnetic blocks is several and they are evenly distributed.

[0015] As a preferred embodiment of the present invention, it includes the following steps; S1; The user connects the oil pump body to the machine bracket, then pushes the turntable backward. The turntable moves backward, causing the rotating rod to move backward until the magnetic coupling plate and the bolt are magnetically connected. Then, the turntable is rotated clockwise. The rotation of the turntable causes the rotating rod to rotate, which in turn causes the magnetic coupling plate to rotate.

The rotation of the rotating rod causes the magnetic coupling disk and the bolt to rotate synchronously. The bolt rotates to tighten and install. Then, the rotating rod is pulled forward to drive the magnetic coupling disk to disengage from the bolt and release the magnetic connection. The rotating rod is then rotated counterclockwise. The rotation of the rotating rod cooperates with the threaded sleeve to tighten and fix it, reducing the impact of the magnetic coupling disk on the bolt due to misoperation of the rotating rod.

[0017] 2. The present invention, through the setting of the buffer mechanism, enables the aluminum plate to press against the oil pump body to reduce vibration. When the aluminum plate is impacted, the scissor fork rod folds to buffer the kinetic energy. With the cooperation of the chain to tightly bind, the vibration of the oil pump body during operation is reduced.

[0018] 3. The present invention enables the cooling fan to start working during the operation of the oil pump body by setting up a heat dissipation component. The cooling fan blows air to allow external air to enter the interior of the rear end cover, and the air inside the rear end cover comes into contact with the oil pump body for air cooling.

[0024] As a technical optimization of the present invention, by setting the heat dissipation component 4, the heat dissipation fan 42 can draw external air into the rear end cover 41, and the air entering the rear end cover 41 can perform air cooling on the oil pump body 1.

[0025] refer to Figure 4 A grille 6 is provided on the right side of the inner wall of the rear cover 41, and the grille 6 is used in conjunction with the cooling fan 42.

[0026] As a technical optimization of the present invention, the grille 6 can assist the cooling fan 42 in its operation and also serve as a filter to prevent dust particles in the air from entering the interior of the rear cover 41 and causing pollution.

[0027] refer to Figure 2 A return spring 7 is fixedly connected to the front end of the inner wall of the rectangular plate 32, and the back end of the return spring 7 is fixedly connected to the bottom of the slide plate 33.

[0028] As a technical optimization of the present invention, the reset spring 7 can assist the slide plate 33 in working and at the same time play a role in reset buffering, thus preventing the slide plate 33 from failing to reset after moving.

[0029] refer to Figure 2 The surface of the rotating rod 35 is provided with a helical thread 8, which is used in conjunction with the rotating rod 35.

[0030] As a technical optimization of the present invention, the setting of the oblique thread 8 can assist the rotating rod 35 in working and at the same time play the role of thread fixation, thus avoiding the inability to tighten and fix the rotating rod 35 during rotation.

[0035] refer to Figure 3 Magnetic blocks 11 are fixedly connected to the back end of the magnetic coupling disk 37 and the front end of the bolt 34. There are several magnetic blocks 11, which are evenly distributed.

[0036] As a technical optimization of the present invention, the magnetic block 11 can assist the magnetic coupling disk 37 in working and play a magnetic connection role, thus preventing the magnetic coupling disk 37 from being unable to connect with the bolt 34.

[0037] refer to Figure 2 This includes the following steps; S1; The user connects the oil pump body 1 to the machine bracket, then pushes the turntable 36 to move backward. The turntable 36 moves backward, causing the rotating rod 35 to move backward until the magnetic coupling disk 37 is magnetically connected to the bolt 34. Then, the user rotates the turntable 36 clockwise. The rotation of the turntable 36 causes the rotating rod 35 to rotate, which in turn causes the magnetic coupling disk 37 to rotate. The magnetic attraction of the rotating magnetic coupling disk 37 causes the bolt 34 to rotate as well. The rotation of the bolt 34 completes the tightening and fixing with the bracket, and S2 is executed. S2; After the oil pump body 1 is installed, it is driven to work. Then, the aluminum plate 53 is used to press against the oil pump body 1 to reduce vibration. When the aluminum plate 53 is impacted, the scissor bar 52 folds to buffer the kinetic energy. The chain 54 is used to tightly bind and reduce the vibration of the oil pump body 1 during operation.

[0038] The working principle and usage process of this invention are as follows: During use, the return spring 7 pulls the slide plate 33 backward, causing the bolt 34 to move backward. The bolt 34 passes through the connecting box 31 and connects with the external bracket. Then, the turntable 36 is pushed backward, causing the rotating rod 35 to move backward. The rotating rod 35 causes the magnetic coupling disk 37 to contact the bolt 34 for magnetic connection. Then, rotating the turntable 36 causes the rotating rod 35 to rotate, causing the magnetic coupling disk 37 and the bolt 34 to rotate synchronously. The bolt 34 rotates to tighten the installation. Then, pulling the rotating rod 35 forward causes the magnetic coupling disk 37 to disengage from the bolt 34, releasing the magnetic connection, and then reversing the direction of rotation. The needle rotates the rod 35, and the rod 35 rotates and is tightened with the threaded sleeve 38 to reduce the impact of the magnetic coupling disk 37 on the bolt 34 due to misoperation of the rod 35. After the oil pump body 1 is installed, it is driven to work. Then, the aluminum plate 53 is used to press against the oil pump body 1 to reduce vibration. When the aluminum plate 53 is impacted, the scissor fork 52 folds to buffer the kinetic energy. The chain 54 is used to tightly bind and reduce the vibration of the oil pump body 1 during operation. When the oil pump body 1 is working, the cooling fan 42 draws air from outside the rear end cover 41. The outside air is filtered through the grille 6 and enters the interior of the rear end cover 41. The air inside the rear end cover 41 provides air cooling for the oil pump body 1.

[0039] In summary, this improved electronic fuel pump and its usage method, through the coordinated use of the pump body 1, protective plate 2, connecting mechanism 3, connecting box 31, rectangular plate 32, sliding plate 33, bolt 34, rotating rod 35, turntable 36, magnetic coupling plate 37, threaded sleeve 38, heat dissipation assembly 4, buffer mechanism 5, fixed plate 51, scissor bar 52, aluminum plate 53, and chain 54, solves the problem of existing electronic fuel pumps where the motor part includes a permanent magnet fixed on the housing, an armature that generates electromagnetic torque, and a brush device mounted on the housing.

The installation of this assembly requires special tools and is time-consuming and labor-intensive.
