Description

Technical Field

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

[0002] An oil pump is a mechanical device that transports oil from an oil source to a required system or equipment. The main function of an oil pump is to transport oil from an oil storage tank or oil source to the required equipment or system to maintain the flow of oil and provide appropriate pressure. The housing supports the various components of the oil pump, ensuring the correct position and stable operation of each component. When the oil pump is working, the oil pump housing needs to dissipate the heat generated by the internal mechanical movement.

[0003] Chinese utility model patent (authorization announcement number CN222391467U) discloses a centralized oil pump housing structure, including an integrally machined oil pump housing. The bottom of the oil pump housing has inner and outer rotors, with a drive shaft inside the inner rotor. Both the inner and outer rotors are axially mounted. The bottom of the oil pump housing has an oil inlet and an oil outlet, which are radially opened and connected to the inner and outer rotors. The top of the oil pump housing also has a connector extending in the same direction as the motor and a waterproof and breathable membrane. This prior art provides a centralized oil pump housing structure that is compact, allows for control of motor size, has high motor housing integrity, good sealing at the oil inlet and outlet, long service life, and is easy to assemble and maintain.

[0004] The aforementioned prior art also mentions that several heat dissipation fins are integrally formed on the controller cover. The heat dissipation fins on the surface of the controller cover are integrally formed with the controller cover, which can increase the heat dissipation effect of the controller cover during operation. Since heat dissipation fins can generally only passively exchange heat with the outside air, they are more suitable for low-load, moderate-temperature environments. Under heavy loads or high ambient temperatures, the heat dissipation efficiency of the heat dissipation fins is low, making it difficult for the heat dissipation performance of the oil pump housing structure to meet the heat dissipation requirements of heavy loads or high ambient temperatures. Therefore, we propose an oil pump housing structure. Utility Model Content

[0005] To address the aforementioned issues, an oil pump housing structure is provided. This structure actively and forcibly dissipates heat from inside the housing through an active cooling mechanism. By forcing airflow, more air is directed to the heat dissipation surface, accelerating heat dissipation and removing a large amount of heat in a short time. This increases heat exchange efficiency and solves the technical problem that the low heat dissipation efficiency of the heat sink fins makes it difficult for the oil pump housing structure to meet the heat dissipation requirements of heavy loads or high ambient temperatures.

[0006] To address the problems of existing technologies, this utility model provides an oil pump housing structure, including a base, the upper side of which is connected to a housing, and the two sides of the housing are respectively connected to heat sinks. The oil pump housing structure also includes an active heat dissipation mechanism, a dustproof mechanism, and a cover. An active heat dissipation mechanism for actively dissipating heat from inside the housing is provided on the side of the housing near the heat sink. A dustproof mechanism for preventing dust in the air from entering the housing is provided on the active heat dissipation mechanism. A cover for preventing foreign objects from hitting the dustproof mechanism is provided on the dustproof mechanism.

[0007] Preferably, the active heat dissipation mechanism includes a mounting base and a heat dissipation component; the mounting base is connected to the side of the housing near the heat sink; the heat dissipation component is disposed on the mounting base.

[0008] Preferably, the dustproof mechanism includes a filter plate, a connecting frame, and an anti-clogging component; the filter plate is disposed on the outside of the heat dissipation component; the connecting frame is rotatably disposed on the filter plate; and one end of the anti-clogging component is connected to the connecting frame.

[0009] Preferably, the dustproof mechanism further includes a guiding mechanism, a docking mechanism, and a positioning mechanism; the guiding mechanism is disposed on the filter plate and the anti-clogging component, and is used to enhance the stability of the anti-clogging component. The docking mechanism is disposed on the heat dissipation component and the connecting frame, and is used to cooperate with the heat dissipation component to drive the anti-clogging component to move through the connecting frame; the positioning mechanism is disposed on the mounting base and the filter plate, and is used to help temporarily limit the filter plate to be positioned relative to the mounting base.

[0010] Preferably, the guiding mechanism includes a slider and an annular groove; the slider is connected to the end of the anti-clogging component away from the connecting frame; the annular groove is formed on the side of the filter plate near the slider.

[0011] Preferably, the docking mechanism includes a docking block and a docking groove; the docking block is connected to the working end of the heat sink; the docking groove is opened on the side of the connecting frame near the docking block, and the docking groove is used to engage with the docking block.

[0012] Preferably, the positioning mechanism includes a first magnetic block and a second magnetic block; the first magnetic block is embedded in the side of the filter plate near the mounting base; the second magnetic block is embedded in the side of the mounting base near the first magnetic block.

[0013] Preferably, the cover includes a limiting mechanism for limiting the cover and the mounting seat. The limiting mechanism includes a connecting plate, a slot, and a screw. The connecting plate is connected to the cover. The slot is located on the side of the mounting seat near the connecting plate. The screw passes through the filter plate and is threadedly connected to the slot.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. By actively dissipating heat from inside the casing through an active cooling mechanism, more airflow is directed to the heat dissipation surface through forced airflow, which can accelerate heat dissipation and remove a large amount of heat in a short time, thereby increasing heat exchange efficiency. This solves the technical problem that the heat dissipation efficiency of the heat dissipation fins is low, making it difficult for the heat dissipation performance of the oil pump housing structure to meet the heat dissipation requirements of heavy loads or high ambient temperatures.

[0016] 2. The dust and lint on the outside of the filter plate are cleaned by the anti-clogging component of the dustproof mechanism, which prevents dust and lint from clogging the filter plate and ensures that the filter plate always maintains a high ventilation efficiency. This allows the heat dissipation components to operate stably and solves the technical problem of reduced heat dissipation effect of the heat dissipation components due to filter plate clogging when the oil pump housing structure starts up.

Detailed Implementation

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1-2 As shown, an oil pump housing structure includes a base 1, the upper side of which is connected to a housing 11. Both sides of the housing 11 are connected to heat sinks 12. The oil pump housing structure also includes an active cooling mechanism, a dustproof mechanism, and a cover 2. An active cooling mechanism for actively dissipating heat from the inside of the housing 11 is provided on the side of the housing 11 near the heat sinks 12. A dustproof mechanism for preventing dust from entering the housing 11 is provided on the active cooling mechanism. A cover 2 for preventing foreign objects from hitting the dustproof mechanism is provided on the dustproof mechanism. The active cooling mechanism includes a mounting base 21 and a heat sink 22. The mounting base 21 is connected to the side of the housing 11 near the heat sinks 12. The heat sink 22 is disposed on the mounting base 21.

[0027] Specifically, the heat sink 22 uses a cooling fan as the implementing element.

[0028] When the oil pump is used in a low-load, moderate ambient temperature environment, the heat sink 12 of the housing 11 can dissipate heat through natural convection of the outside air, without the need for an additional power supply, and only requires periodic cleaning of the dust on the surface of the heat sink 12.

[0029] When the oil pump is used in scenarios with heavy loads and high ambient temperatures, the heat sink 22 is activated, and the cooling fan forces airflow inside the casing 11 to remove a large amount of heat in a short time, thereby accelerating the heat dissipation of the oil pump. At the same time, the fan speed can be adjusted according to the working status and load of the oil pump to achieve more flexible heat dissipation control.

[0030] See Figures 1-7As shown, the dustproof mechanism includes a filter plate 23, a connecting frame 24, and an anti-clogging component 25; the filter plate 23 is disposed on the outside of the heat sink 22; the connecting frame 24 is rotatably disposed on the filter plate 23; one end of the anti-clogging component 25 is connected to the connecting frame 24; the dustproof mechanism also includes a guiding mechanism, a docking mechanism, and a positioning mechanism; the guiding mechanism is disposed on the filter plate 23 and the anti-clogging component 25, and the guiding mechanism is used to enhance the stability of the anti-clogging component 25. The docking mechanism is mounted on the heat sink 22 and the connecting frame 24. The docking mechanism is used to cooperate with the heat sink 22 to drive the anti-blocking component 25 to move through the connecting frame 24. The positioning mechanism is mounted on the mounting base 21 and the filter plate 23. The positioning mechanism is used to help the filter plate 23 temporarily limit its position with the mounting base 21. The guiding mechanism includes a slider 26 and an annular groove 27. The slider 26 is connected to the end of the anti-blocking component 25 away from the connecting frame 24. The annular groove 27 is opened on the side of the filter plate 23 near the slider 26. The docking mechanism includes a docking block 28 and a docking groove 29. The docking block 28 is connected to the working end of the heat sink 22. The docking groove 29 is opened on the side of the connecting frame 24 near the docking block 28. The docking groove 29 is used to cooperate with the docking block 28 for locking and docking.

[0031] Specifically, the anti-clogging component 25 is implemented using a brush that will not damage the filter plate 23. The slider 26 is adapted to the annular groove 27, and the mating block 28 matches the rectangular cross-section mating groove 29. The anti-clogging component 25 and the filter plate 23 are kept in a state of compression contact.

[0032] When the oil pump is running, the filter plate 23 is installed on the outside of the heat sink 22. The filter plate 23 can effectively prevent external dust and lint from entering the interior of the housing 11. When the filter plate 23 is installed on the outside of the heat sink 22, its docking groove 29 docks with the docking block 28. Based on the compatibility between the docking block 28 and the docking groove 29, the two are engaged.

[0033] When the heat sink 22 is activated, the fan blades begin to rotate. Utilizing the rectangular cross-sectional structure of the docking groove 29, the heat sink 22 drives the connecting frame 24 to rotate through the interlocking action of the docking block 28 and the docking groove 29. This, in turn, causes the connecting frame 24 to drive the anti-clogging component 25 to rotate. At this time, the end of the anti-clogging component 25 away from the connecting frame 24 drives the slider 26 to slide along the annular groove 27. Relying on the fitting relationship between the slider 26 and the annular groove 27, the slider 26 provides auxiliary limiting for the anti-clogging component 25, ensuring that the anti-clogging component 25 and the filter plate 23 maintain a stable compression state. Since the anti-clogging component 25 uses a brush that will not damage the filter plate 23 as its implementing element, it can effectively remove dust and lint trapped on the outside of the filter plate 23 during the rotation of the anti-clogging component 25, preventing dust and lint from clogging the filter plate 23.

[0034] See Figures 3-5As shown, the positioning mechanism includes a first magnetic block 210 and a second magnetic block 211; the first magnetic block 210 is embedded in the filter plate 23 on the side near the mounting base 21; the second magnetic block 211 is embedded in the mounting base 21 on the side near the first magnetic block 210; the cover 2 includes a limiting mechanism, which is used to limit the cover 2 and the mounting base 21. The limiting mechanism includes a connecting plate 212, a slot 213 and a screw 214; the connecting plate 212 is connected to the cover 2; the slot 213 is opened on the side of the mounting base 21 near the connecting plate 212; the screw 214 passes through the filter plate 23 and is threadedly connected to the slot 213.

[0035] Specifically, the first magnetic block 210 and the second magnetic block 211 are attracted to each other by magnetism.

[0036] When the filter plate 23 drives the docking groove 29 to engage with the docking block 28, it simultaneously drives the first magnetic block 210 and the second magnetic block 211 to stick together. Based on the magnetic attraction between the first magnetic block 210 and the second magnetic block 211, the filter plate 23 is temporarily fixed to the outside of the heat sink 22.

[0037] At this point, the operator can install the cover 2 onto the outside of the filter plate 23, and then use the screw 214 to pass through the connecting plate 212 and the filter plate 23 in sequence, and screw it into the slot 213. Due to the threaded connection characteristics of the slot 213 and the screw 214, they limit each other, thereby realizing the sequential installation and fixation of the filter plate 23 and the cover 2 on the outside of the heat sink 22. When the filter plate 23 needs to be disassembled for maintenance, the operator only needs to remove the cover 2 to simultaneously remove the filter plate 23 for cleaning, which significantly improves the convenience of disassembling and maintaining the filter plate 23.

[0038] Under the operating conditions of the oil pump housing, the filter plate 23 is first installed on the outside of the heat sink 22, so that the mating groove 29 and the mating block 28 are engaged and assembled, temporarily fixing the filter plate 23 on the outside of the heat sink 22. Then, the cover 2 and the filter plate 23 are fastened to the outside of the heat sink 22 by the screw 214. After the assembly is completed, the heat sink 22 is started, and its power drives the connecting frame 24 to rotate the anti-clogging component 25. During this process, the anti-clogging component 25 cleans the dust and lint adhering to the outside of the filter plate 23, effectively preventing dust and lint from accumulating on the surface of the filter plate 23 and causing blockage, thereby ensuring that the filter plate 23 always maintains a high ventilation efficiency.

[0039] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
