Description

Technical Field

[0001] This disclosure relates to the technical field of oil pump devices, and more specifically, to a filter structure, a pump cover assembly, a pump, and a vehicle. Background Technology

[0002] An electronic oil pump is used to pump oil from the tank into an electric drive system for cooling or lubrication of the transmission structure. To prevent impurities in the oil from entering the pump and affecting its operation, a filter screen is integrated on the pump cover at the oil inlet to filter impurities in the oil. However, in related technologies, the filter screen is easily deformed by the impact of the oil during use, which can cause damage to the filter screen. Utility Model Content

[0003] The purpose of this disclosure is to provide a filter structure, a pump cover assembly, a pump, and a vehicle, wherein the filter structure can prevent the filter from undergoing large deformation under the impact of oil, thereby preventing damage to the filter due to large deformation.

[0004] To achieve the above objectives, a first aspect of this disclosure provides a filter structure, comprising: A filter holder includes an annular frame and a support frame connected to the annular frame, the annular frame forming a flow channel for the passage of a flowing medium; and A filter body is connected to the annular frame and covers the flow channel. The support frame has a connection area covered by the projection of the filter body in the extension direction along the flow channel, and the connection area is connected to the filter body.

[0005] With this configuration, the support frame can support the filter body, preventing it from deforming significantly under the impact of the flowing medium, and thus avoiding damage to the filter body due to excessive deformation.

[0006] In some possible implementations, the filter body has a cross-section that extends outward from its centerline in a curved, zigzag, or wavy manner. This configuration increases the filtration area of ​​the filter body without increasing its projected area in the direction of the flow channel, thereby improving filtration efficiency and extending the lifespan of the filter body. Alternatively, The filter body has a cross-section that extends radially from one side of the flow channel to the opposite side in a curved, broken, or wavy manner. This configuration increases the filtration area of ​​the filter body without increasing the projected area of ​​the filter body in the extension direction of the flow channel. This improves filtration efficiency and extends the service life of the filter body.

[0007] In some possible implementations, the support frame includes at least one support rod connected to the annular frame, the connection area being located on the at least one support rod, and the support rod extending along the connected filter body in a curved, zigzag, or wavy line. This arrangement allows the support rod to provide more stable support to the filter body, reducing vibration of the filter body when subjected to the impact of flowing media, preventing fatigue fracture, and extending the service life of the filter body.

[0008] In some possible implementations, there are multiple support rods, with the first end of each support rod connected to the annular frame, and the second end of each support rod extending towards the centerline of the flow channel and interconnected. The support rods extend from the first end towards the second end in a curved, zigzag, or wavy line. This arrangement provides more stable support for the filter body, ensuring that the filter maintains a stable shape under the impact of the flowing medium, preventing deformation and collapse, thereby maintaining an effective filtration area and filtration efficiency.

[0009] In some possible implementations, the support frame is injection molded to the filter body; this arrangement ensures a stable connection between the support frame and the filter body, wherein the support frame can be made of plastic. This design makes the plastic support frame lightweight and flexible, capable of cushioning vibration and impact, further ensuring that the filter body does not deform when subjected to the impact of the flowing medium. And / or The support frame and the ring frame are integrated, which can improve the overall resistance to deformation and impact of the filter support.

[0010] In some possible implementations, the annular frame includes a connecting portion for insertion into the inlet channel of the pump cover. The connecting portion includes a plurality of snap-fit ​​structures spaced circumferentially along the inlet channel. The snap-fit ​​structures are connected to the pump cover, which facilitates the installation and disassembly of the annular frame.

[0011] In some possible implementations, the connecting portion further includes a plurality of guide structures, which are arranged alternately with the plurality of snap-fit ​​structures along the circumference of the flow channel. The guide structures are used to guide the connecting portion to be inserted into the flow channel, which facilitates the installation of the annular frame on the pump cover.

[0012] In some possible implementations, the guide structure is used to make an interference fit with the inlet channel, thereby improving the stability of the connection between the connection and the pump cover.

[0013] In some possible implementations, the annular frame further includes a limiting part connected to the side of the connecting part away from the flow channel. The limiting part is used to abut against the end of the pump cover to limit the annular frame and prevent the annular frame from being over-installed or not installed properly.

[0014] In some possible implementations, a notch is provided between the snap-fit ​​structure and the guide structure. The notch extends from the end of the connecting portion away from the limiting portion toward the limiting portion, and there is a gap between the bottom of the notch and the limiting portion, which is sufficient to ensure the stability of the connecting portion connected to the pump cover.

[0015] A second aspect of this disclosure provides a pump cover assembly, including a pump cover and a filter structure as provided in the first aspect of this disclosure. The pump cover includes an inlet channel, and the annular frame is inserted into the inlet channel. Thus, when the pump is running and draws in a flowing medium through the inlet channel of the pump cover, the filter body of the filter structure can filter impurities in the flowing medium, preventing impurities from entering the pump and affecting its operation.

[0016] In some possible implementations, the sidewall of the inlet channel is provided with a snap-fit ​​portion, and the snap-fit ​​structure of the annular frame snaps into the snap-fit ​​portion, so that the annular frame is detachably snapped into the pump cover.

[0017] In some possible implementations, the snap-fit ​​portion includes an annular groove extending circumferentially along the inlet channel, and the snap-fit ​​structure includes a claw that snaps into the annular groove. This configuration achieves snap-fit ​​between the snap-fit ​​structure and the snap-fit ​​portion.

[0018] A third aspect of this disclosure provides a pump including a pump cover assembly as provided in a second aspect of this disclosure.

[0019] This disclosure provides a vehicle including the pump provided in the third aspect of this disclosure.

[0020] The above technical solution provides a filter support comprising an annular frame and a support frame connected to the annular frame. The annular frame forms a flow channel for the passage of the flowing medium. The filter body is connected to the annular frame and covers the flow channel. The support frame has a connection area covered by the projection of the filter body along the extension direction of the flow channel, and the connection area is connected to the filter body. This arrangement ensures full contact between the support frame and the filter body, providing stable support. When the flowing medium impacts the filter body through the flow channel, the connection area of ​​the support frame supports the filter body, preventing significant deformation of the filter body under the impact of the flowing medium, and thus preventing damage to the filter body due to excessive deformation.

[0021] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] Unless otherwise stated, directional terms such as "inner" and "outer" refer to the inner and outer contours relative to the outline of the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0026] The first aspect of this disclosure provides a filter structure 10, such as... Figures 1 to 6As shown, the filter includes a filter support 12 and a filter body 11. The filter support 12 includes an annular frame 121 and a support frame 122 connected to the annular frame 121. The annular frame 121 forms a flow channel 13 for the flow of a fluid medium. The filter body 11 is connected to the annular frame 121 and covers the flow channel 13. The support frame 122 has a connection area 12211 covered by the projection of the filter body 11 along the extension direction of the flow channel 13. The connection area 12211 is connected to the filter body 11.

[0027] With the above configuration, the support frame 122 is in full contact with the filter body 11 through the connection area 12211, providing stable support. When the flowing medium impacts the filter body 11 through the flow channel 13, the support frame 122 can support the filter body 11, preventing the filter body 11 from being deformed under the impact of the flowing medium, thereby preventing the filter body 11 from being damaged due to large deformation.

[0028] The filter body 11 can be constructed in any suitable form and can be made of any suitable material.

[0029] In some embodiments, the filter body 11 has a cross-section that curves, breaks, or wavy outwards from its centerline. This configuration increases the filtration area of ​​the filter body 11 without increasing its projected area in the extension direction of the flow channel 13. This improves the filtration efficiency of the filter body 11 for the flowing medium and reduces the likelihood of clogging by impurities in the flowing medium, thus extending its service life and preventing frequent replacements due to clogging. It is understood that the cross-section is a section passing through the centerline of the filter body 11 or a section passing through the central axis of the flow channel 13. For example, in this embodiment, rotating the cross-section around the centerline of the filter body 11 reveals its shape.

[0030] In other embodiments, the filter body 11 has a cross-section that extends radially from one side of the flow channel 13 to the opposite side in a curved, zigzag, or wavy manner. This configuration increases the filtration area of ​​the filter body 11 without increasing its projected area in the extension direction of the flow channel 13. This improves the filtration efficiency of the filter body 11 for the flowing medium; furthermore, the increased filtration area makes the filter body 11 less prone to clogging by impurities in the flowing medium, extending its service life and preventing frequent replacements due to clogging. For example, with... Figure 3Taking the placement direction of the filter body shown as an example, the filter body 11 may have a cross-section that extends from the bottom to the top in the form of a curve, a broken line, or a wavy line. This cross-section may be a section passing through the central axis of the flow channel 13.

[0031] In some implementations, such as Figures 1 to 4 As shown, the filter body 11 includes a wall filter portion 111 connected to the annular frame 121 and protruding outward or recessed in the flow channel 13 along the extension direction of the flow channel 13, and an end filter portion 112 connected to the end of the wall filter portion 111 away from the annular frame 121. The end filter portion 112 includes a groove portion 1122 and a protrusion portion 1121 arranged radially outward from the center line of the end filter portion 112.

[0032] In the above embodiments, the wall filter portion 111 protrudes outward or is recessed inward along the extension direction of the flow channel 13, and the end filter portion 112 includes a groove portion 1122 and a protrusion portion 1121 arranged radially outward from the center line of the end filter portion 112, which can increase the effective filtration area of ​​the filter body 11 and improve the filtration efficiency.

[0033] In some embodiments, the support frame 122 can also be constructed in any suitable form. For example, as... Figure 3 and Figure 6 As shown, the support frame 122 includes at least one support rod 1221 connected to the ring frame 121. The connection area 12211 is located on the at least one support rod 1221. The support rod 1221 extends along the connected filter body 11 in a curved, zigzag, or wavy line. With this arrangement, the support rod 1221 can provide more stable support for the filter body 11, reduce the vibration of the filter body 11 when it is impacted by the flowing medium, avoid fatigue fracture, and extend the service life of the filter body 11.

[0034] In addition, there are multiple support rods 1221. The first end of each support rod 1221 is connected to the ring frame 121. The second end of each support rod 1221 extends toward the center line of the flow channel 13 and is connected to each other. The support rods 1221 extend from the first end toward the second end in a curved, broken, or wavy line.

[0035] In the above embodiments, there are multiple support rods 1221, that is, the support frame 122 includes multiple support rods 1221, which can further provide more stable support for the filter body 11, ensure that the filter maintains a stable shape under the impact of the flowing medium, prevent deformation and collapse, and thus maintain an effective filtration area and filtration efficiency.

[0036] In some implementations, such as Figure 6As shown, multiple support frames 122 can be arranged circumferentially and evenly along the flow channel 13, which can provide uniform support for the filter body 11 and improve the stability of the filter support.

[0037] In some embodiments, the support frame 122 and the filter body 11 can be connected in different ways according to actual needs. For example, the filter body 11 can be made of metal, and the support frame 122 can be made of plastic, and the support frame 122 can be injection molded to the filter body 11. With this configuration, the support frame 122 and the filter body 11 are stably connected, and the plastic support frame 122 is lightweight and flexible, which can buffer vibration and impact, further ensuring that the filter body 11 does not deform when subjected to the impact of the flowing medium.

[0038] In another embodiment, the support frame 122 may also be adhered to the filter body 11. In this embodiment, exemplarily, the support frame 122 may be located downstream of the filter body 11 in the flow direction of the fluid. For example, the support frame 122 may be located on the side of the filter body 11 facing the interior of the flow channel 13. Furthermore, the support frame 122 may also be provided upstream of the filter body 11 in the flow direction of the fluid, meaning that support frames 122 may be provided on opposite sides of the filter body 11. This disclosure does not specifically limit this aspect.

[0039] In some embodiments, the support frame 122 and the annular frame 121 can be constructed as a single unit. For example, the support frame 122 and the annular frame 121 can be made of the same material and integrally molded, or the support frame 122 and the annular frame 121 can be made of different materials and connected as a single unit by injection molding. This disclosure will not elaborate on such variations. In addition, the integral construction of the support frame 122 and the annular frame 121 can significantly improve the manufacturing efficiency of the support frame 122 and the annular frame 121, and the integral molding of the support frame 122 and the annular frame 121 can improve the overall deformation resistance and impact resistance of the filter support 12.

[0040] For example, the support frame 122 and the annular frame 121 can be made of plastic, and the support frame 122 and the annular frame 121 can be injection molded together. Alternatively, the filter body 11 can be made of metal, and the filter body 11 is connected to the annular frame 121. The annular frame 121 can be plastic-coated around the edge of the filter body 11 for fixed connection to the edge of the filter body 11. The support frame 122 supports the filter body 11 to prevent it from deforming under impact. Further details are omitted here.

[0041] In some implementations, such as Figure 3 and Figure 4As shown, the annular frame 121 includes a connecting part 1211, which is used to insert into the feed channel of the pump cover 20. The connecting part 1211 includes a plurality of snap-fit ​​structures 12111 arranged circumferentially along the flow channel 13. The snap-fit ​​structures 12111 are connected to the pump cover 20, which can facilitate the installation and disassembly of the annular frame 121.

[0042] In some embodiments, the connecting part 1211 further includes a plurality of guide structures 12112, and the plurality of guide structures 12112 and the plurality of snap-fit ​​structures 12111 are arranged alternately along the circumference of the flow channel 13. The guide structures 12112 are used to guide the connecting part 1211 to be inserted into the flow channel 21, which facilitates the installation of the annular frame 121 on the pump cover 20.

[0043] In some embodiments, after the connecting part 1211 is inserted into the inlet channel 21, the guide structure 12112 can be interference-fitted with the inlet channel 21, thereby improving the stability of the connection between the connecting part 1211 and the pump cover 20.

[0044] In addition, such as Figure 3 and Figure 4 As shown, the annular frame 121 includes a limiting part 1212, which is connected to the side of the connecting part 1211 opposite to the flow channel 13. The limiting part 1212 is used to abut against the end of the pump cover 20 to limit the annular frame 121 and prevent the annular frame 121 from being over-installed or under-installed. That is, when the annular frame 121 is installed on the pump cover 20 and the limiting part 1212 abuts against the end of the pump cover 20, it indicates that the snap-fit ​​structure 12111 of the annular frame 121 is installed in place.

[0045] In some implementations, such as Figure 4 and Figure 6 As shown, a notch 12113 is provided between the snap-fit ​​structure 12111 and the guide structure 12112. The notch 12113 extends from the end of the connecting portion 1211 away from the limiting portion 1212 toward the limiting portion 1212, and there is a gap between the bottom of the notch 12113 and the limiting portion 1212.

[0046] In the above embodiment, a notch 12113 is provided between the snap-fit ​​structure 12111 and the guide structure 12112. The notch 12113 extends from the end of the connecting part 1211 away from the limiting part 1212 toward the limiting part 1212. In this way, the snap-fit ​​structure can form a cantilever, which can provide elastic deformation space. When the snap-fit ​​structure 12111 is inserted into the inlet channel 21, the snap-fit ​​structure 12111 is pressed against the inner wall of the inlet channel 21 and deforms. When assembled in place, the snap-fit ​​structure 12111 returns to its original shape to snap onto the pump cover 20, forming a stable connection to complete the assembly between the ring frame 121 and the pump cover 20.

[0047] Furthermore, there is a gap between the bottom of the notch 12113 and the limiting part 1212, which can ensure the stability of the connection part 1211 connected to the pump cover 20.

[0048] A second aspect of this disclosure provides a pump cover assembly 100, such as Figures 1 to 6 As shown, the pump cover assembly 100 includes a pump cover 20 and a filter structure 10 as provided in the first aspect of this disclosure. The pump cover 20 includes an inlet channel 21, and an annular frame 121 is inserted into the inlet channel 21.

[0049] In the above embodiment, the annular frame 121 is inserted into the inlet channel 21, which enables the filter structure 10 to be assembled on the pump cover 20. Thus, when the pump is running and draws in the flowing medium through the inlet channel 21 of the pump cover 20, the filter body 11 of the filter structure 10 can filter impurities in the flowing medium, preventing impurities in the flowing medium from entering the pump and affecting the operation of the pump.

[0050] It should be noted that the flowing medium mentioned above is constructed from different substances depending on the application of the pump. For example, when the pump is used to transport water, the flowing medium mentioned above is water; when the pump is used to transport oil, the flowing medium mentioned above is oil. There is no restriction here.

[0051] In some implementations, such as Figures 3 to 5 As shown, the side wall of the inlet channel 21 is provided with a snap-fit ​​part 211, and the snap-fit ​​structure 12111 of the annular frame 121 snaps into the snap-fit ​​part 211 so that the annular frame 121 can be detachably snapped into the pump cover 20.

[0052] In some embodiments, the snap-fit ​​portion 211 includes an annular groove 2110 extending circumferentially along the inlet channel 21, and the snap-fit ​​structure 12111 includes a snap-fit ​​claw 12111a snapping into the annular groove 2110.

[0053] In the above embodiment, the claw 12111a engages with the annular groove 2110 to achieve engagement between the engagement structure 12111 and the engagement part 211.

[0054] In addition, the setting of the annular groove 2110 allows the claw 12111a to be directly inserted into the inlet channel 21 when it is at any position around the inlet channel 21, so as to achieve the engagement with the annular groove 2110, making it more convenient to assemble the annular frame 121 onto the pump cover 20.

[0055] In some other possible embodiments, the snap-fit ​​portion 211 includes an annular protrusion extending circumferentially along the inlet channel 21, and the snap-fit ​​structure 12111 includes a claw 12111a that snaps into the annular protrusion. The claw 12111a snaps into the annular protrusion to achieve the assembly between the annular frame 121 and the pump cover 20. This is not a limitation.

[0056] A third aspect of this disclosure provides a pump including a pump cover assembly 100 as provided in the second aspect of this disclosure. The pump also includes a pump body, and the pump cover assembly 100 is mounted on the pump body. The pump draws in a flowing medium through an inlet channel 21 in the pump cover 20 of the pump cover assembly 100. A filter screen body 11 in the pump cover assembly 100 is capable of filtering the drawn-in flowing medium. The pump cover 20 can be connected to the pump body in any suitable mounting manner with reference to related technologies, which will not be described in detail in this disclosure.

[0057] This fourth aspect of the disclosure provides a vehicle that includes a pump as provided in the third aspect of the disclosure. The vehicle may be a gasoline vehicle, a hybrid vehicle, or an electric vehicle. When the vehicle is a hybrid vehicle or an electric vehicle, the pump may be an electronic oil pump applied to the electric drive system of the vehicle, which will not be described in detail here.

[0058] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0060] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
