Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted actuators, and in particular to a stable pump body structure. Background Art

[0002] Electronic pump actuators are installed on new energy or traditional automobile engines to achieve various functions, such as providing circulation power for cooling oil. Traditional oil pumps are directly connected to the engine and provide power through engine rotation. Their speed is proportional to the engine. They cannot flexibly adjust the oil flow according to actual temperature and other factors, and cannot be accurately controlled. Therefore, they are gradually being eliminated.

[0003] The current mainstream electronic pumps use independent motors to provide power, and use integrated controllers and several high-precision sensors for precise control. They can not only provide different speeds and flows according to different working conditions, but also protect the pump in time under some abnormal conditions (overload, overtemperature, stall, etc.).

[0004] The current electronic pump structure is relatively simple. Based on the current development trend of miniaturization, high power and high integration of electronic actuators, how to reduce product noise and vibration and increase product stability while meeting the needs of the entire vehicle is a problem that needs to be solved urgently. Therefore, it is necessary to improve it. Summary of the invention

During installation, the first connecting piece and the second connecting piece are superimposed and aligned to form a ring structure, and then the bushing is installed between the pump body and the ring structure, so that the pump body can be fixed on the base, and the ring and the base themselves have no direct contact with the pump body, the bushing flexibly connects the pump body and the ring, and its function is to effectively reduce the vibration transmission in the axial, radial, axial rotation, radial rotation and other directions, to ensure that the vibration between the main engine and the pump body is not transmitted, and to avoid the superposition of vibration to cause product failure.

[0007] Preferably, the liner kit includes a buffer body made of rubber material in the middle, and bolt bodies made of metal material are fixed on both sides of the buffer body, and the bolt bodies on both sides of the buffer body are respectively connected to the pump body and the collar.

During the working process, since the buffer body between the pump body and the collar is made of rubber material, the vibration transmission in the axial, radial, axial rotation, radial rotation and other directions can be effectively reduced, ensuring that the vibration between the main engine and the pump body is not transmitted, and avoiding the superposition of vibration to cause product failure.

[0008] Preferably, the bolts at both ends of the buffer body are plastic-coated and fixed inside, and the buffer bodies between the bolt bodies are made of rubber material, and the bolt bodies are not connected.

[0010] Preferably, the number of the lining members is 3. The number of the lining members can be adjusted according to actual conditions, and the present invention is described by taking 3 lining members as an example.

The positioning grooves on the positioning plate are used to facilitate the quick fixing and alignment of various components during installation.

[0013] Preferably, the length of the base is greater than the length of the pump body, and a plurality of positioning holes are provided on the base. The collar structure is wrapped outside the pump body, and the length of the base also exceeds the pump body, which can effectively protect the pump body in both axial and radial directions, and reduce possible damage during transportation and installation. The number of positioning holes on the base can be adjusted according to actual conditions, and the positioning holes on the base are used to fix the base.

[0014] Preferably, the pump body surface is integrally formed with a plurality of sheet-shaped reinforcing ribs. The reinforcing ribs on the pump body surface are integrally formed with the shell, and can effectively increase the overall strength of the shell and increase the heat dissipation capacity.

DETAILED DESCRIPTION

[0023] The technical solution of the invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] Example:

[0025] like Figure 1 and 2 As shown in Figures 3, 4 and 5, a stable pump body structure includes a pump body 1, which is composed of a motor housing, a rotor cover plate and a controller cover plate. The surface of the pump body 1 is integrally formed with a plurality of sheet-like reinforcing ribs 2, and the surface of the pump body 1 is also integrally formed with a waterproof breathable plug mounting hole 3.

[0026] A horizontal base 4 is installed on the outer bottom of the pump body 1 . The length of the base 4 is greater than the length of the pump body 1 , and three positioning holes 5 are opened on the surface of the base 4 .

[0027] Two connecting plates that can be connected to each other are installed on the base 4. The connecting plates include an arc-shaped first connecting plate 6 that is stamped integrally with the base 4. An arc-shaped second connecting plate 7 is installed in the gap between the first connecting plate 6 and the base 4. The first connecting plate 6 and the second connecting plate 7 are connected to form an annular ring structure.

[0028] A positioning plate 8 parallel to the pump body 1 is integrally stamped on the second connecting piece 7 , and a plurality of positioning grooves 9 are formed on the positioning plate 8 .

[0029] Three flexibly connected lining members 10 are installed between the collar and the pump body 1. The lining member 10 includes a buffer body 11 installed between the collar and the pump body 1. The buffer body 11 is made of rubber. Both sides of the buffer body 11 are fixed with bolt bodies 12 made of metal. The bolt bodies 12 on both sides of the buffer body 11 are respectively connected to the pump body 1 and the collar through threads.

[0030] A buffer body 11 made of rubber is disposed between the bolt bodies 12 at both ends, and the two bolt bodies 12 are not connected.

[0031] The plug body 12 is an hourglass-shaped structure with a small diameter in the middle and large diameters at both ends.

[0032] During installation, the first connecting piece 6 and the second connecting piece 7 are overlapped and aligned to form a collar structure, and then the two ends of the bushing 10 are respectively aligned and installed on the pump body 1 and the collar structure, so that the pump body 1 can be fixed on the base 4, and the collar and the base 4 themselves have no direct contact with the pump body 1.

[0033] During operation, since the buffer body 11 between the pump body 1 and the ring is made of rubber, it can effectively reduce the transmission of vibrations in axial, radial, axial rotation, radial rotation and other directions, ensure that the vibration between the main unit and the pump body 1 is not transmitted, and avoid product failure caused by the superposition of vibrations.

[0034] The collar structure is wrapped around the pump body 1, and the length of the base 4 also exceeds the pump body 1, which can effectively protect the pump body 1 in the axial and radial directions and reduce possible damage during transportation and installation.
