[0024] Reference Figure 1-3 This utility model provides a reinforcing rib structure arrangement at the fuel pump mounting location in the gear chamber, including:

[0025] The mounting unit 100 includes a housing 101. A mounting plate 102 is fixedly connected to one end of the outer surface of the housing 101. A reinforcing component 103 is provided on one side of the outer surface of the mounting plate 102. Multiple stepped ribs 105 are fixedly connected to the other side of the outer surface of the mounting plate 102. Multiple extension plates 106 are fixedly connected to the lower surface of the mounting plate 102. Multiple screw holes 108 are formed on the upper surface of the mounting plate 102. A mounting hole 110 is formed in the middle of the upper surface of the mounting plate 102. A second reinforcing plate 104 is fixedly connected to the adjacent sides of the stepped ribs 105 and the extension plates 106. One side of the outer surface of the second reinforcing plate 104 is fixedly connected to the lower surface of the mounting plate 102, and the upper surface of the second reinforcing plate 104 is fixedly connected to the rear outer surface of the housing 101. The stepped ribs 105 evenly bear the external forces on the mounting plate 102 through a distributed layout, forming good bending resistance. The extension plate 106, as a supporting component, works together with the stepped ribs 105 to effectively disperse the pressure borne by the mounting plate 102. The second reinforcing plate 104 connects the stepped ribs 105 and the extension plate 106, further enhancing the overall rigidity of the structure and ensuring the operational stability of the fuel pump. The screw holes 108 provided on the mounting plate 102 provide a multi-point fixing function, enabling the fuel pump to be reliably installed on the gear chamber housing 101. The mounting hole 110 is located in the middle of the mounting plate 102 and can be precisely aligned with the interface of the fuel pump body to ensure no offset during the connection process and improve installation efficiency and stability.

[0026] The reinforcing component 103 includes multiple diagonal braces 103a, one side of which is fixedly connected to the outer surface of the mounting plate 102. A first reinforcing plate 103b is fixedly connected to the adjacent side of each diagonal brace 103a. The lower surface of the first reinforcing plate 103b is fixedly connected to the front surface of the outer shell 101. A protrusion 103c is fixedly connected to the lower surface of each diagonal brace 103a. The outer surface of the protrusion 103c is fixedly connected to the adjacent sides of the mounting plate 102 and the outer shell 101. The diagonal braces 103a are right-angled triangles, and the stepped ribs 105 are stepped. The positions of both the diagonal braces 103a and the stepped ribs 105 are consistent with the screw holes 108. Both the diagonal braces 103a and the stepped ribs 105 are fixedly connected to the outer surface of the outer shell 101. The diagonal brace 103a, with its right-angled triangular design, efficiently converts the vertical load borne by the mounting plate 102 into a horizontal component and transmits the force to the outer shell 101. Its arrangement not only enhances the stability of the overall structure but also effectively reduces stress concentration at a single connection point, thereby reducing fatigue damage. Since the position of the diagonal brace 103a coincides with the screw hole 108, its supporting function during the installation and operation of the fuel pump can reduce deformation or cracking at the screw hole 108 that may be caused by overload. The protrusion 103c, by tightly connecting the mounting plate 102 and the outer shell 101, further improves the rigidity and stability between the components. The first reinforcing plate 103b, by connecting with the diagonal brace 103a, provides additional bending rigidity to the entire reinforcing assembly 103.

[0027] Furthermore, the upper surface of the extension plate 106 is fixedly connected to the rear outer surface of the housing 101, and one end is fixedly connected to another position on the housing 101. A buffer pad 107 is fixedly connected to the upper surface of the mounting plate 102, and a screw hole 108 penetrates the upper surface of the buffer pad 107. A washer 109 is fixedly connected inside the screw hole 108 of the buffer pad 107. The extension plate 106, by connecting the rear outer surface of the housing 101 to other positions, forms a rigid bridge across the components, effectively dispersing the load on the housing 101. The buffer pad 107, fixed to the upper surface of the mounting plate 102, uses its flexible material to absorb local vibration energy at the screw hole 108, preventing excessive impact force from being transmitted to the housing 101, thus protecting and extending the lifespan of the components. The washer 109 is embedded inside the screw hole 108, and its main functions include protecting the surrounding structure of the screw hole 108 from wear, reducing stress concentration during installation, and improving the stability of the screw connection.

[0028] During use, the fuel pump is first placed into the mounting hole 110, and then aligned with the screw holes 108 of the mounting plate 102 for tight installation. The buffer pad 107 and the washer 109 improve the tightness of the screw installation and reduce the impact of fuel pump vibration. The diagonal brace 103a and the stepped brace 105 enhance the overall rigidity of the structure. The first reinforcing plate 103b and the second reinforcing plate 104 increase the connection area between the mounting plate 102 and the outer shell 101, improve the stability of the structure, and thus support a heavier fuel pump, reduce the risk of cracking, and improve ease of use.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
