[0002] In the field of electronic oil pump technology, the mounting system of the electronic oil pump controller is crucial for the stable operation of the entire device. In existing technologies, the electronic oil pump controller is typically mounted using bolts and a combination of clips and a ring-shaped protective plate to fix the controller cover to the housing. This traditional mounting method has several drawbacks: First, to ensure the fixing force, the clips between the controller cover and the housing require extremely high machining precision, increasing production costs and processing difficulty. Second, to enhance the fixing effect, complex reinforcing components are often added, requiring riveting and bonding to prevent detachment, which not only increases the number of components and structural complexity but also increases the difficulty of process management. Third, the lack of effective positioning and anti-rotation mechanisms makes quick and accurate installation difficult, reducing production efficiency. Based on these problems, developing a new electronic oil pump controller mounting system can solve at least one of these issues. Utility Model Content

[0026] Example 1
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fixing system for an electronic oil pump controller includes a housing 1 and a cover plate 7. The housing 1 has a hollow internal cavity. The housing 1 and the cover plate 7 are connected by snap-fit connections. The specific connection method of the snap-fit is not limited; it can be a connection between a snap-fit and a groove, or a connection between a snap-fit and a protrusion. At least two first clamping parts 12 are provided on the outer peripheral surface of the housing 1, and second clamping parts 71 corresponding to the first clamping parts 12 are provided on the outer peripheral surface of the cover plate 7. The first clamping parts 12 and the second clamping parts 71 are connected by a fixing clip 8. Preferably, there are three to four first clamping parts 12. Figure 2 Three clamping parts are shown in the image. The spacing between the first clamping parts 12 is not limited. Preferably, the first clamping parts 12 are evenly spaced on the outer circumferential surface of the housing 1, and the fixing clips 8 are arranged in a one-to-one correspondence with the first clamping parts 12. Preferably, the fixing clips 8 are C-shaped, and the fixing clips 8 firmly clamp the cover plate 7 to the housing 1, thus eliminating the need for riveting, welding, bolting, or other fixing methods as in the prior art.
[0028] In this embodiment, as Figure 2 As shown, at least two fasteners 11 are provided on the upper part of the housing 1, and a locking member 73 corresponding to the fasteners 11 is provided on the cover plate 7. The fasteners 11 are connected to the locking members 73, as shown. Figure 2 As shown, the fastener 11 is disposed on the outer peripheral surface of the housing 1. The fastener 11 is disposed in the form of a protrusion, and the locking member 73 is disposed in the form of a ring. In other embodiments, the specific form and position of the locking member 11 and the fastener 73 are not limited. That is, the fastener 11 can also be disposed inside the housing 1, the fastener 11 can also be disposed in the form of a groove, and the locking member 73 can also be L-shaped, and connected to the groove through the protrusion of the L-shape.
[0029] In this embodiment, the fasteners 11 and the first clamping parts 12 are spaced apart, that is, one first clamping part 12 is provided between two fasteners. Preferably, there are also 3 to 4 fasteners 11. The spacing between the fasteners 11 is not limited, but preferably, the fasteners 11 are equally spaced on the housing 1.
[0030] In this embodiment, at least one of the second clamping portions 71 is provided with a limiting protrusion 72 on its side, and the limiting protrusion 72 is engaged with the side of the first clamping portion 12. Preferably, as shown... Figure 5 As shown, two limiting protrusions 72 are provided, both of which are disposed on both sides of the same second clamping part 71. The limiting protrusions 72 are precisely engaged with the sides of the first clamping part 12, allowing for precise positioning of the cover plate 7 and preventing rotation of the cover plate 7 relative to the housing 1, thus improving assemblability. In other embodiments, the limiting protrusions 72 can also be disposed on different second clamping parts 71. Preferably, the limiting protrusions 72 are disposed on different sides of the second clamping part 71. The limiting protrusions 72 are precisely engaged with different sides of the first clamping part 12, thus restricting clockwise or counterclockwise rotation of the cover plate. Preferably, the limiting protrusions 72 have a certain elastic deformation capability, enabling them to firmly clamp the two sides of the first clamping part 12 through their own elastic deformation. The use of limiting protrusions 72 allows for quick and accurate positioning and installation during assembly, improving production efficiency.
[0031] In this embodiment, a first sealing ring 3 is provided between the housing 1 and the cover plate 7. The first sealing ring 3 can prevent liquid from overflowing from the housing 1, and also prevent external liquids, dust and other objects from entering the housing 1.
[0032] In this embodiment, a motor rotor assembly 2 and a motor stator assembly 4 are disposed in the inner cavity of the housing 1. The motor stator assembly 4 is sleeved on the outer periphery of the motor rotor assembly 2. A controller 5 is disposed on the motor stator assembly 4 and is located on one side of the cover plate 7.
[0033] In this embodiment, a second sealing ring 6 is provided between the controller 5 and the housing 1. The controller 5 can be sealed by the second sealing ring 6.
[0034] In this embodiment, the fixing clip 8 is made of an elastic material. The elastic material can be spring steel, stainless steel, high-strength aluminum alloy, high-strength plastic, etc. The fixing clip 8 can be formed by sheet metal bending or mold processing, preferably by sheet metal bending. The elastic deformation capability of the fixing clip 8 allows the housing 1 and the cover plate 7 to be positioned and clamped together, resulting in fast assembly.
[0035] The beneficial effects of this embodiment are as follows: Through the arrangement of fasteners, clips, a first clamping part, a second clamping part, and a fixing clip, the cover plate and the housing are pre-fixed by the fasteners and clips. Then, they are fixed to the first and second clamping parts by C-clamps, which can firmly clamp the housing and the cover plate. This results in high assemblability, a simple structure, improved production efficiency, and reduced production costs. The limiting protrusions ensure precise installation of the cover plate on the housing, preventing rotation. Compared with existing technologies, the fixing system for an electronic oil pump controller in this embodiment has the advantages of simple structure and low manufacturing precision requirements. It can be clamped and fixed using the elasticity of the fixing clip itself, eliminating the need for complex processes such as subsequent riveting, welding, and bolting, thereby improving assembly convenience, simplifying the structure, and reducing costs.
[0036] Example 2
[0037] The difference between this embodiment and Embodiment 1 is that, in this embodiment, pressure sensors (not shown in the figure) are provided on the first clamping part 12, the second clamping part 71, or the fixing clamp 8. The pressure sensors are connected to the controller 5, and the connection can be wired or wireless, such as via Bluetooth or ZigBee. When the pressure sensor is located on the first clamping part 12, it is preferably located on the upper and lower end faces of the first clamping part. When the pressure sensor is located on the second clamping part 71, it is preferably located on the upper and lower end faces of the second clamping part. When the pressure sensor is located on the fixing clamp, it is preferably located on the inner surfaces of both ends of the C-shaped fixing clamp. When the pressure sensor monitors changes in pressure at the fixing part in real time, it promptly feeds back to the controller if the pressure becomes abnormal (too high or too low). The controller then reminds the user to perform inspection and maintenance to prevent malfunctions caused by loose or overly tight fixing, thereby improving the safety and stability of the electronic oil pump.
[0038] The working principle or operation process in this implementation is as follows: During assembly, the cover plate 7 is connected to the fastener 11 via the clamp 73, achieving pre-fixation between the cover plate 7 and the housing 1. Next, the fixing clamp 8 is clamped onto the first clamping part and the second clamping part, thereby firmly clamping the housing 1 and the cover plate 7, ensuring efficient assembly, structural simplicity, and improved production efficiency while reducing production costs. During the pre-fixation stage between the cover plate 7 and the housing 1, the limiting protrusion 72 can perform precise positioning, ensuring that the cover plate 7 can be accurately installed onto the housing 1, effectively preventing rotation of the cover plate 7 relative to the housing 1. In subsequent use, the pressure sensor can monitor changes in pressure at the fixing point in real time. Once the pressure is abnormal (too high or too low), it promptly feeds back to the controller, which then reminds the user to check and maintain the device to prevent malfunctions caused by loose or overly tight fixing, thus improving the safety and stability of the electronic oil pump.
[0039] The beneficial effects of this embodiment are as follows: by setting up a pressure sensor, the pressure between the housing and the cover plate can be monitored in real time. When an abnormal pressure is detected, the user will be promptly reminded so that the fixing system can be checked and maintained as necessary. This effectively prevents failures caused by improper fixing (loosening or overtightening), thereby enhancing the safety and stability of the electronic oil pump.
[0040] The advantages of this utility model are as follows: Through the arrangement of fasteners, clips, a first clamping part, a second clamping part, and a fixing clip, the cover plate and the housing are pre-fixed by the fasteners and clips. Then, they are fixed to the first and second clamping parts by C-clamps, which can firmly clamp the housing and the cover plate. This results in high assemblability, a simple structure, improved production efficiency, and reduced production costs. The limiting protrusions ensure precise installation of the cover plate on the housing, preventing rotation. The pressure sensor monitors the pressure between the housing and the cover plate in real time. When an abnormal pressure is detected, the user is promptly alerted to perform necessary checks and maintenance on the fixing system, effectively preventing malfunctions caused by improper fixing (loosening or overtightening), thereby enhancing the safety and stability of the electronic oil pump. This utility model provides a fixing system for an electronic oil pump controller. It has the advantages of simple structure and low manufacturing precision requirements. It can be clamped and fixed by the elasticity of the fixing clamp itself, without the need for complex processes such as subsequent riveting, welding, and bolt tightening. This improves the ease of assembly, simplifies the structure, reduces costs, and enables real-time monitoring of the pressure of the fixed part to prevent failures caused by improper fixing.
