Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an oil pump mounting base. Background Technology

[0002] With the rapid development of automotive technology, consumers have increasingly higher requirements for automotive performance indicators. Automotive engine technology is also constantly improving. A series of new technologies such as turbocharging and direct fuel injection are widely used in gasoline engines. Direct injection technology requires high fuel injection pressure, which requires the engine to be matched with a fuel pump to extract fuel and thus ensure a normal fuel supply.

[0003] However, the existing oil pump mounting brackets are usually formed by stamping and flanging metal sheets. If the radius (R) is too small, it will cause stress concentration at the bending point. Under the vibration of the oil pump or external impact load, the stress concentration point is prone to cracking, eventually leading to the breakage of the base of the bracket. Utility Model Content

[0004] The purpose of this application is to provide an oil pump mounting base that has the advantages of improving the support strength of the oil pump mounting base. It solves the problem that the buckles of the existing oil pump mounting bases are usually formed by stamping and flanging metal sheets. If the radius of curvature is too small, it will cause stress concentration at the bending point of the material. Under the vibration of the oil pump or external impact load, the stress concentration point is prone to cracking, which will eventually lead to the breakage of the buckle root.

[0005] The oil pump mounting base provided in this application adopts the following technical solution: an oil pump mounting base includes a mounting ring, an extension ring is fixedly connected to the upper end of the mounting ring, a plurality of buckles arranged in a ring array are fixedly connected to the upper end of the extension ring, a wave groove is provided on the upper end of the inner wall of the plurality of buckles, a slope is provided on the upper end of the plurality of buckles, a plurality of reinforcing grooves arranged in a ring array are provided on the outer wall of the buckles, and a plurality of reinforcing ribs arranged in a ring array are fixedly connected to the outer wall of the plurality of buckles.

[0006] By adopting the above technical solution, multiple annular array clips connected to the upper end of the extension ring at the upper end of the mounting ring form a surrounding fixing structure for the oil pump. Combined with the sloping design at the upper end of the clips, this guides the insertion of the mounting cover plate during installation, reducing alignment difficulty and improving installation efficiency. Simultaneously, the sloping structure increases the R-value of the clips. The thickness at the corners enhances the structural strength of the buckle's stress-bearing parts, reducing the risk of breakage during long-term use. The corrugated grooves on the inner wall of the buckle can engage with the corresponding structure of the oil pump mounting cover. By increasing the contact friction and engagement area, it prevents the oil pump from rotating due to vibration during operation, avoiding loosening caused by the decrease in holding force, and ensuring the stability of the connection. The annular array of reinforcing grooves on the outer wall of the buckle reduces the overall structural weight while optimizing stress distribution. Combined with the reinforcing ribs in the annular array, it further enhances the overall structural strength of the buckle, improving its resistance to deformation and fracture, thus adapting to the vibration environment and load pressure of the oil pump during operation, reducing the probability of buckle damage, and extending the service life of the base. The device increases the structural strength at the buckle's R-corner through the slope setting, and the setting of reinforcing grooves and reinforcing strips optimizes stress distribution, improves its resistance to deformation and fracture, and thus extends its service life.

[0007] Preferably, a fixing groove is provided through one side of the outer wall of each of the multiple buckles.

[0008] By adopting the above technical solution, the setting of the fixing groove allows the buckle and the oil pump mounting ring to be further locked by bolts, pins and other connecting parts, forming a double fixing mechanism. When the oil pump is in use, it will vibrate. The cooperation between the fixing groove and the connecting parts can effectively reduce the rotation of the oil pump mounting ring and improve the stability of the overall connection. During the assembly process, the fixing groove can be used as a positioning reference to prevent the buckle connection from failing due to misalignment or insufficient rotation.

[0009] Preferably, the bottom end of the inner wall of the mounting ring is provided with a first rounded corner.

[0010] By adopting the above technical solution, the design of the first rounded corner eliminates the right-angle structure at the bottom of the inner wall of the mounting ring, avoiding stress concentration at the right angle under load. When the oil pump is fixed on the mounting ring by the buckle and vibrates, the rounded corner structure can make the stress evenly distributed on the inner wall of the mounting ring, reducing the risk of material fatigue cracking and improving the overall structural strength and service life of the base.

[0011] Preferably, a second rounded corner is provided between the mounting ring and the extension ring.

[0012] By adopting the above technical solution, the second rounded corner connecting the mounting ring and the extension ring eliminates the right-angle structure at the connection between the two components, disperses the stress generated by oil pump vibration or external impact, and avoids excessive stress concentration at the connection, which could lead to cracking.

[0013] Preferably, the mounting ring has multiple mounting holes arranged in a ring array inside.

[0014] By adopting the above technical solution, the mounting hole layout of the ring array conforms to industry standards, making the base widely applicable. By passing bolts or fasteners through the mounting holes, the mounting ring can be fixed in the installation position, ensuring the stability and reliability of the connection. Multiple mounting holes evenly distribute the vibration and impact force generated during the operation of the oil pump, avoiding structural damage caused by single-point force. The ring array design of the mounting holes provides a clear positioning reference, allowing operators to quickly align the mounting holes inside the mounting ring with the corresponding holes on the installation position, reducing assembly difficulty.

[0015] Preferably, the outer wall of the mounting ring is provided with a positioning groove.

[0016] By adopting the above technical solution, the positioning groove opened on the outer wall of the mounting ring can cooperate with the positioning protrusion or guide on the fixed position during the installation process to form an alignment reference. This can guide the mounting ring to find the correct installation angle and position, avoid misalignment during installation, shorten the installation and debugging time, and improve assembly efficiency.

[0017] Preferably, a shock-absorbing pad is fixedly connected to the bottom end of the mounting ring, and the shock-absorbing pad has multiple through holes arranged in a ring array inside.

[0018] By adopting the above technical solution, the vibration damping pad can directly absorb the vibration energy generated during the operation of the oil pump. It can buffer the vibration impact through its own elastic deformation, reduce the transmission of vibration, and reduce the noise during equipment operation. The through hole is designed so that when the connector passes through the mounting hole, it can pass through the vibration damping pad through the through hole, ensuring a stable connection between the mounting ring and the mounting position.

[0019] Preferably, the shock-absorbing pad is made of rubber.

[0020] By adopting the above technical solution, the vibration damping pad is made of rubber material. Rubber material has excellent elasticity and toughness, and can absorb and buffer the vibration generated by the operation of the oil pump through its own deformation, converting vibration energy into elastic deformation, reducing vibration transmission efficiency, reducing the impact on the installation foundation and surrounding equipment. Its surface friction coefficient is large, which can enhance the friction between the installation ring and the installation foundation. Combined with the fixing effect of the installation hole, it further prevents the base from shifting during vibration and improves the overall stability of the installation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: This oil pump mounting base, through the design of a ring array of snap fasteners, wavy grooves, ramps, reinforcing grooves, and reinforcing ribs, increases the structural strength of the device and thus enhances the stability of the mounting base. During installation, the ramp at the upper end of the snap fastener guides the oil pump mounting cover to smoothly insert, improving installation efficiency. The engagement of the wavy groove with the oil pump mounting cover, combined with the fixing groove and the double locking of the connector, prevents loosening due to oil pump vibration, ensuring a stable connection. The ramp thickens the R-angle of the snap fastener, increasing its structural strength. The reinforcing groove and reinforcing rib optimize stress distribution, improving the snap fastener's resistance to deformation and fracture. The first and second rounded corners are used to disperse the stress of the mounting base, adapting to vibration and load environments and extending service life. The rubber shock-absorbing pad absorbs vibration through its own elasticity, reducing the impact of vibration on surrounding components, while also increasing the friction between the mounting ring and the mounting position, further ensuring installation stability. This device increases the structural strength of the snap fastener's R-angle through the ramp design, and optimizes stress distribution through the reinforcing groove and reinforcing strip, improving its resistance to deformation and fracture, thereby extending its service life.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0025] Example 1: An oil pump mounting base, as shown in the figure. Figure 1 , Figure 2 and Figure 3The system includes a mounting ring 1, with an extension ring 2 fixedly connected to the upper end of the mounting ring 1. Multiple snap fasteners 3 arranged in a ring array are fixedly connected to the upper end of the extension ring 2. These multiple ring array snap fasteners 3 connected to the upper end of the extension ring 2 form a surrounding fixing structure for the oil pump. The upper end of the inner wall of each snap fastener 3 is provided with a corrugated groove 4, which can engage with the corresponding structure of the oil pump mounting cover. By increasing the contact friction and engagement area, the system prevents the oil pump from rotating due to vibration during operation, avoids loosening due to pressure reduction, and ensures the stability of the connection. The upper end of each snap fastener 3 is provided with a ramp 5. The ramp 5 design at the upper end of the snap fastener 3 guides the insertion of the mounting cover during the installation process, reducing the alignment difficulty during assembly and improving installation efficiency. Simultaneously, the ramp 5 structure increases the R... The thickness at the corners enhances the structural strength of the stress-bearing parts of the buckle 3, reducing the risk of breakage during long-term use. Multiple reinforcing grooves 6 arranged in a ring array are provided on the outer wall of each buckle 3. Multiple reinforcing ribs 7 arranged in a ring array are fixedly connected to the outer wall of each buckle 3. The ring array of reinforcing grooves 6 on the outer wall of the buckle 3 reduces the overall structural weight while optimizing stress distribution. Combined with the ring array of reinforcing ribs 7, the overall structural strength of the buckle 3 is further enhanced, improving its resistance to deformation and fracture. This allows it to adapt to the vibration environment and load pressure during the operation of the oil pump, reducing the probability of buckle 3 damage and extending the service life of the base.

[0026] Example 2: An oil pump mounting base, referring to... Figure 1 , Figure 4 and Figure 5Multiple clips 3 have a fixing groove 8 extending through one side of their outer wall. The fixing groove 8 allows for further locking of the clips 3 and the oil pump mounting ring 1 using bolts, pins, or other connecting parts, forming a double fixing mechanism. When the oil pump vibrates during use, the cooperation between the fixing groove 8 and the connecting parts effectively reduces the rotation of the oil pump mounting ring 1, improving the overall connection stability. During assembly, the fixing groove 8 can serve as a positioning reference, preventing the clips 3 from failing due to misalignment or insufficient rotation. The bottom of the inner wall of the mounting ring 1 has a first rounded corner 9. The design of the first rounded corner 9 eliminates the right-angle structure at the bottom of the inner wall of the mounting ring 1, avoiding stress concentration at the right angle under load. When the oil pump is fixed to the mounting ring 1 by the clips 3 and generates... During vibration, the rounded corner structure allows for uniform stress distribution on the inner wall of the mounting ring 1, reducing the risk of material fatigue cracking and improving the overall structural strength and service life of the base. A second rounded corner 10 is provided between the mounting ring 1 and the extension ring 2, connecting the mounting ring 1 and the extension ring 2. This eliminates the right-angle structure at the connection point of the two components, dispersing the stress generated by oil pump vibration or external impact, and preventing excessive stress concentration at the connection point that could lead to cracking. Multiple mounting holes 11 arranged in a circular array are perforated inside the mounting ring 1. The layout of the circular array of mounting holes 11 conforms to industry standards, giving the base wide versatility. By passing bolts or fasteners through the mounting holes 11, the mounting ring 1 can be fixed in the installation position, ensuring the stability and reliability of the connection. The mounting holes 11 evenly distribute the vibration and impact forces generated during the operation of the oil pump, avoiding structural damage caused by single-point stress. The annular array design of the mounting holes 11 provides a clear positioning reference, allowing operators to quickly align the mounting holes 11 inside the mounting ring 1 with the corresponding holes on the installation position, reducing assembly difficulty. The outer wall of the mounting ring 1 has a positioning groove 12, which can cooperate with the positioning protrusion or guide on the fixed position during installation to form an alignment reference, guiding the mounting ring 1 to find the correct installation angle and position, avoiding misalignment, shortening installation and debugging time, and improving assembly efficiency. The bottom end of the mounting ring 1 is fixedly connected to a shock-absorbing pad 13, and the shock-absorbing pad 13 has multiple through holes arranged in an annular array inside. 14. The vibration damping pad 13 can directly absorb the vibration energy generated during the operation of the oil pump. Through its own elastic deformation, it buffers the vibration impact, reduces vibration transmission, and lowers the noise level during equipment operation. The through hole 14 allows the damping pad 13 to pass through the mounting hole 11 when the connector passes through it, ensuring a stable connection between the mounting ring 1 and the installation position. The damping pad 13 is made of rubber, which possesses excellent elasticity and toughness. It can absorb and buffer the vibration generated during the operation of the oil pump through its own deformation, converting vibration energy into elastic deformation, reducing vibration transmission efficiency, and minimizing the impact on the installation foundation and surrounding equipment. Its high surface friction coefficient enhances the friction between the mounting ring 1 and the installation foundation.In conjunction with the fixing function of mounting holes 11, the base is further prevented from shifting during vibration, thus improving the overall stability of the installation.

[0027] The implementation principle of this application embodiment is as follows: During operation, the installation angle and position are first determined by the positioning groove 12 on the outer wall of the mounting ring 1 cooperating with the positioning structure of the installation position. Then, the base is fixed to the installation position using bolts and other fasteners through the annular array mounting holes 11 inside the mounting ring 1. The rubber shock-absorbing pad 13 is pressed between the mounting ring 1 and the installation position. Its own elasticity and the through hole 14 structure can absorb the vibration generated by the oil pump during operation, reduce vibration transmission and enhance friction, and prevent the base from shifting. When installing the oil pump, the oil pump mounting cover slides in along the slope 5 at the upper end of the buckle 3. The slope 5 guides it to smoothly embed between the buckles 3 in the annular array. The wave groove 4 on the inner wall of the buckle 3 engages with the corresponding structure of the mounting cover to form a preliminary fixation. Then, bolts or pins are inserted through the fixing groove 8 on the outer wall of the buckle 3 to further lock the buckle 3 and the mounting cover, forming a double fixation to prevent the oil pump from loosening or rotating when vibrating. During operation, the reinforcing groove 6 on the outer wall of the buckle 3 optimizes the stress distribution, and the reinforcing rib 7 enhances the structural strength. Combined with the thickened buckle 3 R of the slope 5, the buckle 3 is further fixed. The corners enhance the buckle 3's resistance to deformation and fracture. The second rounded corner 10 between the mounting ring 1 and the extension ring 2, and the first rounded corner 9 on the inner wall of the mounting ring 1, disperse stress, prevent excessive local stress from causing cracking, and ensure that the overall structure remains stable under vibration and load, thereby achieving stable installation and reliable operation of the oil pump.
