Description

Technical Field

[0001] This utility model belongs to the field of oil pump technology, and relates to a pump body control box cover plate connection structure and an electronic oil pump. Background Technology

[0002] With the rapid development of the automotive industry, electronic oil pumps are widely used in vehicle lubrication and / or cooling systems, primarily providing a power source for these systems. In some existing technical solutions, the controller of the electronic oil pump is directly immersed in oil to cool it.

[0003] Therefore, the pump body needs to be directly connected to the control box cover. Currently, bolts, welding, or hot riveting are commonly used for fixing, which results in high costs and inconvenient disassembly, leaving considerable room for improvement. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a pump body control box cover connection structure and an electronic oil pump.

[0005] The objective of this utility model can be achieved through the following technical solution: a pump body control box cover connection structure, comprising:

[0006] The pump body has snap-fit ​​protrusions on its inner wall;

[0007] The control box cover is provided with a snap-fit ​​connector, the snap-fit ​​connector has a snap-fit ​​recess, the snap-fit ​​connector is an elastic element, the control box cover can be snapped with the snap-fit ​​protrusion of the pump body through the snap-fit ​​connector, the inner circumference of the snap-fit ​​protrusion is greater than or equal to the outer circumference of the snap-fit ​​recess;

[0008] When the snap-fit ​​connector engages with the snap-fit ​​protrusion, the snap-fit ​​protrusion is located within the snap-fit ​​recess.

[0009] In the above-mentioned pump body control box cover connection structure, the pump body also has a first positioning surface, and the control box cover has a second positioning surface. When the snap-fit ​​connector is snapped into the snap-fit ​​protrusion, the first positioning surface contacts the second positioning surface.

[0010] In the above-mentioned pump body control box cover connection structure, the snap-fit ​​protrusion has a first sliding portion. The first sliding portion is located at one end of the snap-fit ​​protrusion near the control box cover. The inner circumference of the first sliding portion gradually decreases as it approaches the control box cover. When the control box cover approaches the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the first sliding portion, thereby squeezing itself.

[0011] In the above-mentioned pump body control box cover connection structure, the snap-fit ​​recess has a first fitting part, the shape of which is adapted to the shape of the first sliding part.

[0012] In the above-mentioned pump body control box cover connection structure, the snap-fit ​​connector also has a second sliding part. The second sliding part is located at one end of the snap-fit ​​connector near the pump body. The outer periphery of the second sliding part gradually decreases as it approaches the snap-fit ​​arm. When the control box cover is close to the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the second sliding part, thereby squeezing itself.

[0013] In the above-mentioned pump body control box cover connection structure, the snap-fit ​​protrusion has a third sliding part, which is located at the end of the snap-fit ​​protrusion away from the control box cover. The inner circumference of the third sliding part gradually increases as it approaches the control box cover. When the control box cover moves away from the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the third sliding part, thereby squeezing itself.

[0014] In the above-mentioned pump control box cover connection structure, the snap-fit ​​recess also has a fourth sliding part. The fourth sliding part is located at one end of the snap-fit ​​recess near the pump body. The outer periphery of the fourth sliding part gradually increases as it approaches the pump body. When the control box cover moves away from the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the fourth sliding part, thereby squeezing itself.

[0015] An electronic oil pump is also provided, including the aforementioned pump body control box cover connection structure.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. The control box cover can be snapped onto the pump body via a snap-fit ​​connector, replacing the original bolt connection method. Installation and disassembly are simple and convenient. The pump body and control box cover can be connected together simply by snapping them together, which also saves costs.

[0018] 2. When the snap-fit ​​connector engages with the snap-fit ​​protrusion, the first positioning surface contacts the second positioning surface, thereby positioning the pump body and the control box cover, while also ensuring the sealing between the two.

[0019] 3. When the control box cover is close to the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the first sliding part, thereby squeezing itself. Therefore, without manually pressing the snap-fit ​​connector, the snap-fit ​​protrusion can be bent by the mutual proximity between the control box cover and the pump body, thus achieving the fastening.

[0020] 4. The snap-fit ​​recess has a first fitting part that matches the shape of the first sliding part, so as to fit well with the first sliding part and achieve a stable connection.

[0021] 5. When the control box cover is close to the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the second sliding part, thereby squeezing itself. Therefore, without manually pressing the snap-fit ​​connector, the snap-fit ​​protrusion can be bent by the mutual proximity between the control box cover and the pump body, thus achieving the fastening.

[0022] 6. When the control box cover moves away from the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the third sliding part, thereby squeezing itself. Therefore, without manually pressing the snap-fit ​​connector, the snap-fit ​​protrusion bends due to the mutual separation between the control box cover and the pump body, thus unlocking the device.

[0023] 7. When the control box cover moves away from the pump body, the snap-fit ​​connector slides along the snap-fit ​​protrusion through the fourth sliding part, thereby squeezing itself. Therefore, without manually pressing the snap-fit ​​connector, the snap-fit ​​protrusion bends due to the mutual separation between the control box cover and the pump body, thus unlocking the device.

[0045] In this embodiment, when the snap-fit ​​connector 210 snaps into the snap-fit ​​protrusion 110, the first positioning surface 120 contacts the second positioning surface 230, thereby positioning the pump body 100 and the control box cover 200, while also ensuring the sealing between the two.

[0046] like Figures 1-8 As shown, based on the above embodiment, the snap-fit ​​protrusion 110 has a first sliding portion 111. The first sliding portion 111 is located at one end of the snap-fit ​​protrusion 110 near the control box cover plate 200. The inner circumference of the first sliding portion 111 gradually decreases as it approaches the control box cover plate 200. When the control box cover plate 200 approaches the pump body 100, the snap-fit ​​connector 210 slides along the snap-fit ​​protrusion 110 through the first sliding portion 111, thereby squeezing itself.

[0047] In this embodiment, when the control box cover 200 approaches the pump body 100, the snap-fit ​​connector 210 slides along the snap-fit ​​protrusion 110 via the first sliding part 111, thereby squeezing itself. Therefore, without manually pressing the snap-fit ​​connector 210, the snap-fit ​​protrusion 110 can be bent by the mutual proximity between the control box cover 200 and the pump body 100, thereby achieving the fastening.

[0048] like Figures 1-8As shown, based on the above embodiment, the snap-fit ​​recess 220 has a first adapter portion 221, the shape of which is adapted to the shape of the first sliding portion 111.
