Description

Technical Field

[0001] The invention relates to the field of engine oil variable displacement pumps, in particular to an assembly structure of an engine oil variable displacement pump. Background Art

[0002] The variable oil pump, a core component in the engine lubrication system, often faces strict installation constraints imposed by the overall engine layout. To accommodate this limited space, the pump's size must be minimized to meet compact design requirements. However, this reduction in pump volume directly constrains the dimensions of key internal structures like the rotor and chamber, significantly limiting the pump's theoretical oil delivery rate per unit time and making it difficult to meet the engine's lubricant requirements under high-load conditions. To address the issue of insufficient flow in small variable oil pumps, existing technologies typically increase the drive motor power, driving the rotor at a higher speed to improve pumping efficiency. However, this solution has significant drawbacks: the high-power motor drives the rotor at high speeds, significantly increasing the relative speed between the rotor and mating components such as the pump body's inner wall and blades. It also significantly increases the workload on the rotor—including centrifugal force generated by high-speed rotation, fluid impact loads, and friction losses. Under these long-term high-load conditions, the rotor material is prone to cracking and increased wear due to accumulated fatigue, and in severe cases, even fracture, leading to oil pump failure. Furthermore, the high-speed operation of the rotor can cause increased vibration and noise in the pump body. Therefore, achieving high flow output within the limited installation space while avoiding damage caused by excessive rotor load has become a key technical bottleneck hindering the performance and reliability of the oil variable pump.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] In one embodiment, please refer to the appendix of the specification. Figure 1-9 As shown, the present invention describes an oil variable pump assembly structure, comprising a pump body 1, a pump cover 2 provided on the pump body 1, a pulley 3 provided on the pump cover 2, a rotor 5 provided on the pump body 1, and the rotor 5 is connected to the pulley 3, and is characterized in that the rotor 5 rotates to push the oil to move; a regulating valve 4 is provided on the pump body 1, and the regulating valve 4 is used to control the flow of oil entering the interior of the pump body 1; a bushing 6 is provided inside the pump body 1, and the bushing 6 cooperates with the rotor 5, and when the rotor 5 rotates faster, the oil flow rate inside the pump body 1 increases.

[0018] In order to increase the flow rate of the oil inside the pump body 1, a rotor 5 is provided inside the pump body 1. When the rotor 5 rotates, the rotor 5 pushes the oil into the pump body 1. When the rotor 5 rotates faster, the flow rate of the oil entering the pump body 1 becomes larger, and the oil flow rate becomes larger, and additional flow rate can be increased when the rotor 5 rotates at a higher speed; the oil flow rate entering the pump body 1 is adjusted by the regulating valve 4, so that when the rotor 5 rotates, the additional oil flow rate can be increased, and the bushing 6 can cooperate with the rotation of the rotor 5 to convey the oil; when the rotor 5 rotates, the bushing 6 cooperates with the rotor 5 to extend and retract to realize the variable of oil delivery. Therefore, when the pump body 1 is small in size, it is easy to install on the engine. The pump body 1 is small in size but generates variables in the process of conveying flow rate, so that it can rely on variables to realize oil delivery during operation, without additionally increasing the speed of the oil pump, which makes the oil pump have a longer service life.

[0019] The rotor 5 is provided with a blade assembly 50, which is a retractable structure. When the rotor 5 rotates at a fast speed, the blade assembly 50 retracts greatly and the oil flow increases; when the rotor 5 rotates at a slow speed, the blade assembly 50 retracts less and the oil flow decreases.

[0020] The blade assembly 50 includes a blade seat 51 arranged on the rotor 5, and a blade plate 52 is provided on the blade seat 51 to match it. A slide plate 53 is provided on the blade plate 52. A plate groove 54 is opened on the blade seat 51, and the slide plate 53 slides inside the groove.

[0021] Preferably, a second elastic member 55 is provided at the bottom of the guard plate, and the end of the second elastic member 55 is connected to the bottom of the plate slot 54. The second elastic member 55 can pull the slide plate 53 to move inside the slide slot, thereby resetting the slide plate 53 and returning the extended slide plate 53 to its original position. The second elastic member 55 can be a spring, and the stroke of the second elastic member 55 is greater than the length of the slide slot, so that the second elastic member 55 can be returned to its original position after extension without being damaged by the stretched spring.

[0022] In order to enable the blade assembly 50 to be adjusted during use, thereby changing the amount of oil transported inside the pump body 1 and realizing oil variable; when the speed of the rotor 5 is low, due to insufficient centrifugal force, the blade 52 that rotates to the top will not extend out of the inside of the blade seat 51, and since the bottom of the blade 52 fits against the inner wall of the bushing 6, the blade 52 is squeezed, and the blade 52 that rotates to the bottom of the bushing 6 will not fall down, and the oil can still be transported; when a large amount of oil needs to be transported, at this time, the speed of the rotor 5 needs to be increased. When the speed of the rotor 5 is faster, due to the action of centrifugal force, the blade 52 rotates and moves outward from the inside of the blade seat 51, the slide plate 53 slides inside the slide groove, the blade 52 extends, and the blade 52 unfolds and fits against the bushing 6; at this time, the oil entering the pump body 1 is transported outward from the inside of the pump body 1 at the maximum flow rate.

[0023] The pump body 1 is provided with an oil inlet 11 and an oil outlet 12 , and both the oil inlet 11 and the oil outlet 12 cooperate with the bushing 6 .

[0024] The oil inlet 11 and the oil outlet 12 provided on the pump body 1 facilitate the transportation of engine oil from the oil inlet 11 to the oil outlet 12 .

[0025] The bushing 6 is provided with two through holes 65, and a flow-increasing groove is provided inside the bushing 6, a flow-increasing port 62 is provided at one end of the flow-increasing groove, and an outlet 64 is provided at the other end of the flow-increasing groove, and the flow-increasing groove is used to increase the flow of the engine oil; a first baffle 63 is provided on one side of the flow-increasing port 62, and a second baffle 67 is provided on one side of the outlet 64, and first guide plates 61 are provided on both sides of the first baffle 63, and the first guide plates 61 are in contact with the end of the vane 52, and the vane 52 slides on the surface of the first guide plates 61; when the vane 52 is extended, the engine oil is pushed from the flow-increasing port 62 into the interior of the flow-increasing groove and discharged from the outlet 64; a second guide plate 66 is provided on each side of the second baffle 67, and the second baffle 67 is used to limit the flow of the engine oil and allow the engine oil to enter the through hole 65; The first guide plate 61 and the second guide plate 66 are both arc-shaped structures. When the blade 52 contacts the surfaces of the first guide plate 61 and the second guide plate 66 , the blade 52 slides along the surfaces of the first guide plate 61 and the second guide plate 66 .

[0026] The flow-increasing port 62 is arranged on one side of the oil inlet 11. When the engine oil enters the pump body 1, the engine oil will enter one side of the flow-increasing port 62 from the through hole 65 on the bushing 6. When the vane 52 rotates, the engine oil is pressurized to one side of the first baffle 63. The engine oil on one side of the first baffle 63 will enter the interior of the oil-increasing port, and the engine oil moves along the inside of the flow-increasing groove. The engine oil inside the flow-increasing groove is discharged from the flow outlet 64. The flow outlet 64 is located on one side of another through hole 65. The through hole 65 is connected to the oil outlet 12, and the oil outlet 12 discharges the engine oil; the first guide plate 61 is arranged to be an arc-shaped structure. When the rotating vane 52 rotates to contact the first guide plate 61, the first vane 52 contracts. At this time, the vane 52 is always in contact with the first guide plate during the rotation process. The plate 61 is fitted, and the first guide plate 61 is a two-section arc structure. One arc allows the vane 52 to move up along the arc direction, and the other arc allows the vane 52 to move down along the arc direction; so that the vane 52 will not be damaged during the rotation process, thereby increasing the service life; the role played by the second guide plate 66 is the same as that of the first guide plate 61 during the rotation of the vane 52; the first baffle 63 and the second baffle 67 are both used to block the engine oil, the first baffle 63 allows the engine oil to enter the inside of the oil inlet 11, and the second baffle 67 allows the engine oil to enter the inside of the through hole 65, so that the engine oil can be quickly transported from the oil inlet 11 of the pump body 1 to the oil outlet 12 during the transportation process, making the variable efficiency higher.

[0027] The regulating valve 4 includes a valve body 41 arranged on the oil inlet 11, and a blocking ball 43 and a first elastic member 42 are arranged inside the valve body 41. The end of the first elastic member 42 is provided with a blocking ball 43, and the first elastic member 42 is used to push the blocking ball 43 to reset; a filter plate 44 is provided inside the valve body 41, and a blocking plate 45 is provided on the filter plate 44. The blocking plate 45 slides on the filter plate 44 to adjust the oil intake.

[0028] In order to further adjust the oil intake when the variable is small, the oil intake is adjusted after the oil intake increases. When the oil intake increases, the blocking plate 45 moves, and the blocking plate 45 slides from the filter plate 44, so that the mesh on the filter is opened. After the mesh is opened, the flow of the oil is increased; thereby, when the rotor 5 rotates rapidly, the oil intake from the oil inlet 11 is increased.

[0029] The regulating valve 4 also includes a regulating port 48 arranged on the valve body 41, and at least two sliding rods 49 are provided on the regulating port 48, and sliders 410 are provided on the sliding rods 49 in a one-to-one correspondence. The valve body 41 is provided with a sliding groove corresponding to the slider 410, and the slider 410 slides on the sliding groove. A pull rod 47 is provided on the regulating port 48, and the end of the pull rod 47 is connected to the pull rope 46, and the end of the pull rope 46 is fixed on the blocking plate 45.

[0030] In order to compensate for the flow of oil inside the bushing 6, the oil is allowed to flow toward the inside of the bushing 6 through the regulating port 48. When the rotor 5 rotates faster, the amount of oil adsorbed becomes larger. The amount of oil is pushed by the rotation of the vane 52 to be discharged from the oil outlet 12. When the oil is discharged from the oil outlet 12, negative pressure is generated inside the pump body 1, causing the oil to enter from the oil inlet 11 at an accelerated speed. When the amount of oil entering increases, the regulating port 48 drives the slide rod 49 to move, and the movement of the slide rod 49 drives the slider 410 to slide on the inner wall of the valve body 41. After the port 48 slides, a gap is left between it and the valve body 41, and the engine oil is discharged from the gap between the valve body 41 and the regulating port 48, so that the flow rate of the engine oil becomes larger to meet the flow rate of the engine oil inside the pump body 1; when the regulating port 48 moves, the regulating port 48 moves downward by pulling the pull rod 47, and the movement of the pull rod 47 drives the pull rope 46 to move, and the movement of the pull rope 46 drives the sealing plate 45 to move. After the sealing plate 45 moves, the holes on the filter plate 44 are opened, which increases the flow rate of the engine oil so that the flow rate of the engine oil meets the demand for oil transportation inside the pump body 1.

[0031] Preferably, a spring is provided on the pull rod 47, and the spring is used to push the pull rod 47 to reset; a spring is provided on one side of the blocking plate 45, and the spring is used to push the blocking plate 45 to reset.

[0032] When the speed of the rotor 5 becomes slower, the oil flow inside the pump body 1 is not that large. At this time, there is no need for a large amount of oil to enter the interior of the pump body 1. Under the action of the spring, the blocking plate 45 is reset. After a long period of use, some impurities will accumulate on the blocking plate 45, and the impurities will enter the surface of the filter plate 44 located on one side of the blocking plate 45, forming an accumulation. When the flow rate needs to be increased, the speed of the rotor 5 is fast, and the blocking plate 45 is pulled to move by the negative pressure. After the blocking plate 45 is pulled, the blocked holes are opened. Since impurities accumulate on the filter plate 44, the oil intake is affected. The blocking plate 45 is moved away, and the blocking plate 45 is lowered. The square holes are not blocked by impurities, so the flow rate entering the pump body 1 increases; when the blocking plate 45 is reset, the blocking plate 45 will push the impurities accumulated on the filter plate 44 to one side; when the impurities completely affect the oil intake, the regulating mechanism can be removed from the oil inlet 11 for cleaning, and the filter plate 44 can be cleaned by backwashing to clean the impurities on the surface of the filter plate 44. The regulating mechanism after cleaning is installed on the oil inlet 11 for continued use; the oil flow entering the pump body 1 is adjusted by the regulating mechanism to meet the oil amount entering the pump body 1.

[0033] When the present invention is in use, when the amount of engine oil needs to be increased, the rotor 5 needs to rotate quickly, so that the blade assembly 50 on the rotor 5 is extended. When the rotation speed of the rotor 5 is faster, due to the action of centrifugal force, the blade 52 rotates and moves outward from the inside of the blade seat 51, the slide plate 53 slides inside the slide groove, the blade 52 extends, and the blade 52 unfolds and fits with the bushing 6; when the engine oil enters the pump body 1, the engine oil will enter one side of the flow-increasing port 62 from the through hole 65 on the bushing 6, and the engine oil will be pressurized to one side of the first baffle 63 when the blade 52 rotates. The engine oil on one side of the first baffle 63 will enter the inside of the oil-increasing port, and the engine oil moves along the inside of the flow-increasing groove. The engine oil inside the flow-increasing groove is discharged from the outlet 64. The outlet 64 is located on one side of another through hole 65, and the through hole 65 is connected to the oil outlet 12, and the oil outlet 12 discharges the engine oil. During this process, the regulating port 48 allows the oil to flow toward the inside of the bushing 6. When the rotor 5 rotates faster, the amount of adsorbed oil increases, and the amount of oil is pushed by the rotation of the vane 52 to discharge the oil from the oil outlet 12. When the oil is discharged from the oil outlet 12, negative pressure is generated inside the pump body 1, causing the oil to enter from the oil inlet 11 at an accelerated speed. When the amount of oil entering increases, the regulating port 48 drives the slide rod 49 to move, and the movement of the slide rod 49 drives the slider 410 to slide on the inner wall of the valve body 41. After the regulating port 48 slides, a gap is left between it and the valve body 41, and the oil is discharged from the gap between the valve body 41 and the regulating port 48, so that the flow rate of the oil increases to meet the flow rate of the oil inside the pump body 1; when the regulating port 48 moves, the regulating port 48 moves downward by pulling the pull rod 47, and the movement of the pull rod 47 drives the pull rope 46 to move, and the movement of the pull rope 46 drives the blocking plate 45 to move When the oil pump 1 is in a closed position, the oil filter 44 is opened and the oil pump 1 is turned back to the pump 1. When the oil pump 1 is in a closed position, the oil pump 1 is turned back to the pump 1. When the oil pump 1 is in a closed position, the oil pump 1 is turned back to the pump 1. When the oil pump 1 is in a closed position, the oil pump 1 is turned back to the pump 1. When the oil pump 1 is in a closed position, the oil pump 1 is turned back to the pump 1. When the oil pump 1 is in a closed position, the oil pump 1 is turned back to the pump 1.
