Description

Technical Field

[0001] This utility model relates to the field of electronic oil pump technology, and in particular to an electronic oil pump with high-efficiency oil cooling. Background Technology

[0002] With economic development and the rapid growth of the automotive industry, users now have higher requirements for vehicle intelligence and comfort, in addition to demanding power and stability.

[0003] To ensure the cooling and lubrication of various engine components, an electronic oil pump is needed to power the oil circulation. The electronic oil pump is powered by an internal motor, which drives the impeller (inner and outer rotors) to circulate the oil, thereby cooling and lubricating the relevant components. According to different customer needs, oil pumps are developing towards higher levels of sophistication, higher power, and smaller size. The heat dissipation problem of oil pumps in limited spaces is an urgent problem to be solved. The current oil pump structure is relatively simple, and the heat dissipation and lubrication effect of the oil pump is limited, which cannot meet the higher production requirements. Therefore, it is necessary to improve it. Utility Model Content

[0004] This utility model provides an optimized product structure that utilizes oil pump fluid to effectively dissipate heat and lubricate the controller and motor components within the oil pump. This solves the problem of high heat generation in electronic oil pumps under high load operation, providing a highly efficient oil-cooled electronic oil pump that can meet higher user demands. It also addresses the technical problems of existing electronic oil pumps, such as their simple structure, limited heat dissipation and lubrication effects, and the fact that having the inlet and outlet on the same side can have a certain impact, thus failing to meet higher user requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a high-efficiency oil-cooled electronic oil pump, including an oil pump body, the oil pump body including an outer oil pump housing, a bottom pump head structure, a top controller module and a middle motor module, the top of the oil pump body is provided with a controller cover plate, the oil inlet of the oil pump body is opened on the top controller side, and the oil outlet of the oil pump body is opened on the bottom pump head; an oil baffle is provided in the oil inlet at the top of the oil pump body, and the mounting surfaces of the oil pump housing, the controller housing and the controller cover plate are all assembled with a groove structure; the oil flows into the oil pump from the oil inlet, passes through the controller and the motor module and then flows into the pump head structure, and finally flows out through the oil outlet on the pump head. This invention optimizes the original structure where the oil inlet and outlet are on the same side. The oil inlet is located on the controller end, and the oil outlet is on the pump head at the other end. An oil baffle is installed inside the oil inlet. When oil flows in, it first impacts the baffle and then flows into the controller through the gap below the baffle, effectively preventing direct impact on the controller and avoiding damage to its electronic components. The assembly of the electronic oil pump with the controller housing and cover uses a grooved structure, which facilitates assembly, improves assembly stability, and reduces the risk of oil leakage. The electronic oil pump of this invention can utilize oil for efficient lubrication and cooling. The separate inlet and outlet effectively avoid the negative effects of having them on the same side, improving product stability and ease of installation.

[0006] Preferably, the oil baffle is a "plug" type structure with an integrally formed limiting buckle structure at the bottom. During installation, the oil baffle is pressed into the oil inlet, and the limiting buckle at the bottom of the oil baffle secures it to prevent it from falling off. When oil flows in, it first impacts the oil baffle, and then flows into the controller through the gap below the oil baffle, effectively preventing the oil from directly impacting the controller.

[0007] Preferably, the limiting buckle structure is segmented. In this invention, the limiting buckle structure is segmented, not a continuous ring structure, to ensure smooth oil flow and can be adjusted according to actual conditions.

[0008] Preferably, the top diameter of the oil baffle is the largest to receive oil impact, while the middle diameter is smaller to allow oil to flow in. In this invention, the top diameter of the oil baffle is the largest, and the diameter of the middle section is smaller than the diameter of the oil inlet. The top of the oil baffle is used to receive oil impact, and the oil flows downward through the gap in the middle section.

[0009] Preferably, the surface of the oil baffle is provided with a flow channel to enhance the flow rate. The flow channel can be adjusted according to the flow rate requirements, and it is optional to choose whether to provide a flow channel on the surface of the oil baffle. This utility model is illustrated by taking an example where no concave flow channel is provided on the surface of the oil baffle.

[0010] Preferably, the oil baffle is fitted with a removable sealing ring in the middle section, with the sealing ring positioned between the oil baffle and the oil inlet. The sealing ring acts as a buffer, similar to a spring, and can be installed or removed as needed.

[0011] Preferably, an oil passage is provided on the baffle between the controller and the motor module inside the oil pump body, through which oil flows into the motor. The oil passage on the baffle between the controller and the motor ensures that the function of the baffle itself is not altered, and does not affect the flow of oil into the motor.

[0012] Therefore, the high-efficiency oil-cooled electronic oil pump of this utility model has the following advantages: the product structure is optimized, and the oil pump can effectively dissipate heat and lubricate the controller and motor inside the oil pump, solving the problem of high heat generation of electronic oil pumps under high load operation, and meeting the higher usage requirements of users.

Detailed Implementation

[0022] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example:

[0024] like Figure 1 and 2 As shown in Figures 3, 4, 5, 6, 7, and 8, an efficient oil-cooled electronic oil pump includes an oil pump body 1. The oil pump body 1 includes an outer oil pump housing 2, a bottom pump head structure 3, a top controller module, and a middle motor module. A controller cover plate 4 is installed on the top of the oil pump body 1, and a controller housing is installed inside the oil pump body 1. The oil pump housing 2 is assembled with the controller housing and the controller cover plate 4 using a groove structure on their assembly surfaces.

[0025] An oil inlet 5 is provided on the controller cover plate 4 at the top of the oil pump body 1, and an oil outlet 6 is provided on the pump head at the bottom of the oil pump body 1. An oil baffle 7 is installed inside the oil inlet 5 at the top of the oil pump body 1.

[0026] An oil passage 8 is provided on the baffle between the controller and the motor module inside the oil pump body 1, and the oil flows downward into the motor through the oil passage 8.

[0027] The oil flows into the oil pump through the inlet 5, passes through the controller and motor module, then flows into the pump head structure 3, and finally flows out through the outlet 6 on the pump head.

[0028] The oil baffle 7 has a "plug" type structure. The top diameter of the oil baffle 7 is larger than the middle diameter. The top of the oil baffle 7 is used to receive the impact of the oil, and the oil flows downward from the middle section of the oil baffle 7.

[0029] The bottom of the oil baffle 7 is integrally formed with a limiting buckle structure 9, which is segmented to facilitate the downward flow of oil. A removable sealing ring 10 is sleeved and installed in the middle section of the oil baffle 7, and the sealing ring 10 is placed between the oil baffle 7 and the oil inlet 5.

[0030] This utility model optimizes the original structure where the oil inlet and outlet 6 are on the same side to an oil inlet 5 on the controller end and an oil outlet 6 on the pump head at the other end. An oil baffle 7 is installed inside the oil inlet 5. When oil flows in, it first impacts the oil baffle 7 and then flows into the controller from the gap below the oil baffle 7, effectively preventing the oil from directly impacting the controller and avoiding damage to the electronic components on the controller.

[0031] An oil passage 8 is provided on the baffle between the controller and the motor, so that the function of the baffle itself is not changed and the flow of oil into the motor is not affected.

[0032] In this utility model, the assembly of the electronic oil pump with the controller housing and controller cover plate 4 adopts a groove structure, which facilitates assembly, improves assembly stability, and reduces the risk of oil leakage.

[0033] The electronic oil pump of this invention can use oil for efficient lubrication and cooling. By using separate inlet and outlet ports 6, the influence of inlet and outlet ports 6 being on the same side can be effectively avoided, thus improving the stability of the product and the ease of installation.

[0034] The specific embodiments described herein are merely illustrative of the concept of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
