[0022] Example 1 See Figures 1 to 4 As shown, the oil guiding device provided in this application is installed on a housing with an oil passage. The oil guiding device includes an oil guiding component 101 and a mounting component. The oil guiding component 101 is injection molded; the housing has a mounting hole, and the oil guiding component 101 is installed in the mounting hole; the oil guiding component 101 is provided with a manifold 104, an oil inlet 102, and an oil outlet 103, both of which are connected to the manifold 104; the oil inlet 102 is located in the middle of the oil guiding component 101 and is connected to the oil passage; the oil outlet 103 is located at one end of the oil guiding component 101; the mounting component is located at the other end of the oil guiding component 101; the mounting component is connected to the housing to limit the movement of the oil guiding component 101.

[0023] Specifically, the oil guide component 101 of this application can be manufactured using plastic materials (such as PA66, PPS, PPA, etc.) through injection molding, exhibiting good oil compatibility, temperature resistance, and mechanical properties. Compared to traditional metal (such as ADC12 aluminum alloy) cover structures, the material density is lower, and the weight of the components is significantly reduced. The oil guide component 101 integrates the manifold 104, oil inlet 102, and oil outlet 103 through a one-time injection molding process, simplifying the process flow and significantly reducing both raw material and processing costs, which is beneficial for large-scale mass production and cost control.

[0024] Furthermore, the oil guide component 101 integrates a manifold 104, an oil inlet 102, and an oil outlet 103, which can collect lubricating oil from the housing oil passage and guide it to the parts to be lubricated, thereby achieving precise oil guiding. The manifold 104 design helps to balance oil pressure, stabilize flow rate, and improve lubrication uniformity and cooling effect.

[0025] The oil guiding device provided in this application achieves a synergistic improvement in lightweight, low cost, and high reliability of the oil guiding structure through material innovation, structural optimization, and process integration, solving the problems of large weight, high cost, and complex process of existing oil guiding structures.

[0026] In an optional embodiment, the oil guide 101 includes a main body 105 and a nozzle 106. The main body 105 includes a cylinder 107, a first end plate 108, and a second end plate 109. The cylinder 107, the first end plate 108, and the second end plate 109 surround and form a confluence cavity 104. An oil inlet 102 is provided on the side wall of the cylinder 107. A through hole is provided on the first end plate 108. The nozzle 106 is connected to the outside of the first end plate 108, and the spray chamber of the nozzle 106 communicates with the through hole to form an oil outlet 103.

[0027] In this embodiment, the main body 105 of the oil guide 101 is formed by the cylinder 107, the first end plate 108, and the second end plate 109, creating a closed manifold 104. This allows the oil entering from the side wall oil inlet 102 to be collected and buffered within this cavity, improving the integration and stability of the oil circuit system. The nozzle 106 communicates with the manifold 104 to precisely spray the lubricating oil onto the parts to be lubricated. The nozzle 106 can control the flow rate of the lubricating oil, enhancing the smoothness and uniformity of the oil flow.

[0028] In an optional embodiment, the size of the manifold 104 gradually decreases along the flow direction of the medium in the axial direction of the cylinder 107.

[0029] In this embodiment, by setting the manifold 104 to a gradually decreasing size structure, the natural acceleration and steady flow guidance of the oil under the condition of no external power is realized by utilizing the continuity law of the fluid itself. This not only improves the injection efficiency and system response speed, but also improves the flow field uniformity and anti-clogging ability.

[0030] In an optional embodiment, the oil guide 101 further includes a first reinforcing part; the first reinforcing part is disposed on the outer side of the first end plate 108; the first reinforcing part includes a first enclosure 110 and a first reinforcing rib 111, the first enclosure 110 is located at the circumferential edge of the first end plate 108, and the first reinforcing rib 111 is disposed between the first enclosure 110 and the nozzle 106.

[0031] In this embodiment, by providing a first reinforcing part consisting of a first enclosure 110 and first reinforcing ribs 111 on the outer side of the first end plate 108, the structural strength and assembly reliability of the nozzle 106 connection are significantly improved. The first enclosure 110 forms a circumferential boundary constraint frame, and there are multiple first reinforcing ribs 111 arranged radially between the first enclosure 110 and the nozzle 106, forming a structural support bridge from the edge of the end plate to the root of the nozzle 106. This increases the connection strength and effectively prevents structural deformation and loosening of the nozzle 106.

[0032] In an optional embodiment, the oil guide 101 further includes a second reinforcing part; the second reinforcing part is disposed on the outer side of the second end plate 109; the second reinforcing part includes a second enclosure 112 and a second reinforcing rib 113, the second enclosure 112 is located at the circumferential edge of the second end plate 109, and the second reinforcing rib 113 is located within the area enclosed by the second enclosure 112.

[0033] In this embodiment, the structure of the second end plate 109 is reinforced by providing a second reinforcing part consisting of a second enclosure 112 and a second reinforcing rib 113 on the outside of the second end plate 109. The second enclosure 112 forms a circumferential boundary constraint frame, and there are multiple second reinforcing ribs 113 connected in a cross shape to increase strength, effectively preventing structural deformation.

[0034] In an optional embodiment, the oil guide 101 further includes a limiting part; the oil guide 101 is provided with a limiting part at one end away from the oil outlet 103, and a limiting platform is provided on the wall of the mounting hole, with the limiting part being engaged with the limiting platform.

[0035] In this embodiment, as Figures 2 to 4 As shown, the limiting part is specifically a circumferentially protruding edge 114, and the edge 114 is connected to the second enclosure 112; the hole wall of the mounting hole is correspondingly provided with a limiting platform that cooperates with the edge 114, and the edge 114 and the limiting platform form a snap-fit ​​positioning, realizing the axial positioning and reliable stop of the oil guide 101 in the assembly direction, effectively solving the problems of position offset, uneven depth, loosening and falling off that are easy to occur in the traditional installation process.

[0036] In an optional embodiment, the limiting part is provided with a weight reduction cavity 115. Specifically, the weight reduction cavity 115 is a cavity formed by the edge 114, which realizes the lightweighting of the structure and reduces the use of materials.

[0037] In an optional embodiment, the mounting component is a retaining ring 116. The mounting hole wall is provided with a limiting groove. The retaining ring 116 is installed in the limiting groove and abuts against the limiting portion, thereby forming an axial bidirectional limiting structure for the oil guide component 101. This significantly improves the stability and anti-loosening ability of the oil guide component 101 during installation. The retaining ring 116 structure occupies less space and is lighter in weight, allowing for locking of the oil guide component 101 in confined installation spaces, thus saving even more space.

[0038] Example 2 The oil guiding device in this second embodiment is an improvement based on the above embodiments. The technical content disclosed in the above embodiments will not be described again, and the content disclosed in the above embodiments also belongs to the content disclosed in this second embodiment.

[0039] See Figure 4As shown, in an optional embodiment, the oil guide 101 is provided with a sealing groove 117 in the circumferential direction, and an O-ring 118 is installed in the sealing groove 117. Preferably, sealing grooves 117 are provided on both sides of the oil inlet 102 in the axial direction of the cylinder 107.

[0040] In this embodiment, by providing a sealing groove 117 in the circumferential direction of the oil guide 101 and arranging sealing grooves 117 on both sides of the oil inlet 102 in the axial direction, double-seal protection of the oil inlet area and uniform sealing pressure distribution throughout the circumference are achieved, which significantly improves the sealing reliability between the oil guide 101 and the mounting hole and prevents lubricating oil leakage.

[0041] Example 3 This application provides a motor in embodiment three, which includes the oil guiding device of any of the above embodiments. Therefore, it has all the beneficial technical effects of the oil guiding device of any of the above embodiments, which will not be repeated here.
