Technical Field

[0001] The utility model relates to the field of automobile fuel system components, in particular to a novel fuel pump bracket assembly fixing buckle module. Background Art

[0002] In modern vehicles, the fuel pump assembly is a key component of the fuel injection system. Its primary function is to draw fuel from the fuel tank, establish the appropriate fuel pressure through the fuel pressure regulating valve, and then deliver the pressurized fuel to the fuel supply line to ensure proper engine operation. To accommodate fuel tanks of varying shapes and sizes, traditional fuel pump bracket assemblies typically utilize an integrated flange and fuel tank design. However, this design is inflexible for complex or unusual fuel tank shapes and sizes, making it difficult to meet the requirements of all vehicle models.

[0003] With the development of the automotive industry and technological advancements, the market has placed higher demands on fuel pump bracket assemblies, including but not limited to simpler assembly processes, higher stability and reliability, and better adaptability. To address these issues, a split fuel pump bracket assembly design has emerged in recent years, where the flange and fuel tank are no longer integrated, but assembled as separate components. While this change improves product flexibility, it also introduces a new technical challenge: how to quickly and securely install the fuel tank assembly into the fuel tank while ensuring it does not shift or fall off during vehicle operation. This application addresses this technical issue, providing improvements. Utility Model Content

[0004] The utility model proposes a novel fuel pump bracket assembly fixing buckle module, which can ensure that the oil storage barrel assembly is installed in the fuel tank and ensures that it will not be displaced or fall off during vehicle operation, solving the above-mentioned problems existing in the use process of the prior art.

[0005] The technical solution of the present utility model is achieved as follows: a new type of fuel pump bracket assembly fixing buckle module, including an oil storage barrel, a fixing buckle and a fuel tank, the outer side wall of the oil storage barrel is provided with a mounting groove for the fixing buckle to be installed therein, the bottom of the oil storage barrel is provided with a barrel avoidance groove penetrating into the mounting groove, the barrel avoidance groove is used for the fixing buckle to enter the mounting groove from bottom to top, the oil storage barrel is integrally formed with a barrel limiting circular rib on the front side of the avoidance groove, the fixing buckle is integrally formed with a buckle elastic rib plate, the buckle elastic rib plate is used to limit the fixing buckle when it is installed in the mounting groove and is set on the upper side of the barrel limiting circular rib, the bottom of the fuel tank is fixedly connected with a fuel tank limiting hook, and the fixing buckle is provided with a buckle fixing rib plate for engaging with the lower side of the fuel tank limiting hook.

[0006] Preferably, a plurality of connecting rings are integrally formed on the bottom of the oil storage barrel on a side away from the mounting groove, and a fixing boss corresponding to the connecting ring and used to insert the connecting ring from bottom to top is provided at the bottom of the oil tank.

[0007] Preferably, the mounting groove is used for the fixing buckle to be installed so as to slide up and down, and the oil storage barrel is fixedly connected with a barrel limiting hook on both sides of the mounting groove, and buckle limiting grooves for the barrel limiting hook to be engaged are provided on both sides of the fixing buckle.

[0008] Preferably, the oil storage barrel is provided with barrel fixing ribs on both sides of the mounting groove, and the barrel fixing ribs cover the front of both sides of the fixing buckle.

[0009] Preferably, the fixing buckle is integrally formed with a buckle push-pull convex plate protruding forward.

[0010] Preferably, a buckle limiting slot is provided on the rear side of the buckle push-pull convex plate, and a barrel limiting buckle is provided in the installation slot of the oil storage barrel. The barrel limiting buckle is used to be inserted into the buckle limiting slot, and a buckle avoidance groove is also provided on the lower side of the buckle limiting slot on the rear side of the fixed buckle.

[0011] Preferably, the fixing buckle is made of POM copolymer material.

[0012] In summary, the beneficial effects of the present invention are:

[0013] 1. The fixing buckle is installed in the installation groove of the oil storage barrel, and is limited by the buckle elastic rib and the barrel limit circular rib to prevent the fixing buckle from falling out of the installation groove of the oil storage barrel. The buckle fixing rib on the fixing buckle is engaged with the lower side of the oil tank limit hook of the oil tank, thereby forming a quick and stable locking between the oil storage barrel and the oil tank.

[0014] 2. The position of the oil storage barrel is restricted by inserting the fixing boss on the bottom of the fuel tank into the connecting ring. In this way, when the fixing rib on the fixing buckle is engaged with the lower side of the fuel tank limit hook of the fuel tank, it can ensure that the oil storage barrel will not be displaced or fall off during the operation of the vehicle, providing reliable locking performance.

[0015] 3. The fixing buckle can move up and down within the installation slot. When the fixing buckle is lifted, it is in the unlocked state. The tank limit hook inside the fuel tank interferes with the buckle fixing rib of the fixing buckle, causing the tank limit hook to retreat backwards. At this time, the tank limit hook cannot lock the oil storage barrel assembly. When the fixing buckle is pressed down, it is in the locked state. The buckle fixing rib moves downward to the lower side of the tank limit hook, and the tank limit hook abuts against the surface of the fixing buckle. At this time, the tank limit hook locks the oil storage barrel assembly, effectively preventing the oil storage barrel assembly from shaking. At the same time, a barrel limit buckle is provided on the oil storage barrel, and the fixing buckle is provided with a buckle limit slot and a buckle avoidance groove. When in the locked state, the barrel limit buckle abuts against the buckle limit slot to ensure that the fixing buckle will not detach. When in the unlocked state, the barrel limit buckle is in the buckle avoidance groove and does not affect installation.

[0016] 4. The barrel fixing rib is used to prevent the fixing buckle from falling out of the installation slot.

[0017] 5. The forward-facing buckle push-pull plate provides an obvious gripping point for the operator, making it easy to lift or press the buckle.

[0018] 6. The fixing buckle is made of POM copolymer material, which has good dimensional stability and mechanical strength, and is self-lubricating and resistant to chemical corrosion, adapting to the complex working environment of the automobile fuel system. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is a combination of the appended examples of the present invention Figure 1-12 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] Example:

[0035] like Figures 1 to 12As shown, the utility model discloses a novel fuel pump bracket assembly fixing buckle module, including a fuel storage barrel 1, a fixing buckle 2 and a fuel tank 3 (only the bottom of the fuel tank 3 is shown in the figure. Since the fuel tank 33 belongs to the prior art, other structures are not described in detail here). A mounting groove 16 for mounting the fixing buckle 2 is provided on the outer wall of the fuel storage barrel 1, and a barrel avoidance groove 15 penetrating into the mounting groove 16 is provided at the bottom of the fuel storage barrel 1. The barrel avoidance groove 15 is used for the fixing buckle 2 to enter the mounting groove 16 from bottom to top. The fuel storage barrel 1 is integrally formed with a barrel limiting rib 14 on the front side of the avoidance groove, and a barrel limiting rib 14 is formed on the fixing buckle 2. The body is formed with a buckle elastic rib plate 23, which is used to limit the position when the fixing buckle 2 is installed in the mounting groove 16 and is set on the upper side of the barrel limiting circular rib 14. When pushed from bottom to top, the buckle elastic rib plate 23 of the fixing buckle 2 is squeezed by the barrel limiting circular rib 14 of the oil storage barrel 1. The buckle elastic rib plate 23 bends inward without affecting the pushing work. After being pushed into place, the buckle elastic rib plate 23 pops outward and interferes with the barrel limiting circular rib 14 to limit the downward displacement of the fixing buckle 2. In addition, a fuel tank limiting hook 31 is fixedly connected to the bottom of the fuel tank 3, and the fixing buckle 2 is provided with a buckle fixing rib plate 24 for engaging with the lower side of the fuel tank limiting hook 31.

[0036] In addition, two connecting rings 17 are integrally formed on the bottom of the oil storage barrel 1 on the side away from the mounting groove 16, and the bottom of the fuel tank 3 is provided with a fixing boss 32 corresponding to the connecting ring 17 and used to insert the connecting ring 17 from bottom to top. During installation, the fixing boss 32 on the bottom of the fuel tank 3 is inserted into the connecting ring 17 to limit the position of the oil storage barrel 1. In this way, when the buckle fixing rib 24 on the fixing buckle 2 is engaged with the lower side of the fuel tank limit hook 31 of the fuel tank 3, it can ensure that the oil storage barrel 1 will not be displaced or fall off during the operation of the vehicle, providing reliable locking performance.

[0037] Furthermore, the mounting groove 16 is used for the fixing buckle 2 to be installed so as to slide up and down, and the oil storage barrel 1 is fixedly connected with the barrel limiting hook 12 on both sides of the mounting groove 16. The fixing buckle 2 is provided with a buckle limiting groove 22 on both sides for the barrel limiting hook 12 to be engaged. The barrel limiting hook 12 and the buckle limiting groove 22 of the fixing buckle 2 are locked with each other to limit the upward displacement of the fixing buckle 2. The fixing buckle 2 has two installation forms with different heights on the oil storage barrel 1. When the fixing buckle 2 is lifted, as shown in FIG. Figure 9 and Figure 10 As shown, at this time, it is in the unlocked state, the barrel limiting hook 12 is located in the buckle limiting groove 22, and the tank limiting hook 31 inside the fuel tank 3 interferes with the buckle fixing rib 24 of the fixing buckle 2, causing the tank limiting hook 31 to retreat backward. At this time, the tank limiting hook 31 cannot lock the oil storage barrel assembly; when the fixing buckle 2 is pressed down, the barrel limiting hook 12 goes up beyond the buckle limiting groove 22 and reaches the buckle upper notch 27 on the upper side of the buckle limiting groove 22, as shown in FIG. Figure 7 and Figure 8As shown, in this locked state, the buckle fixing rib 24 moves downward to the underside of the tank limit hook 31, which abuts against the surface of the fixing buckle 2. The tank limit hook 31 now locks the oil storage barrel assembly, effectively preventing the oil storage barrel 1 from shaking. The fixing buckle 2 has a compact structure and a rational design, a short molding cycle, easy dimensional control, and high plastic deformation, meeting production and assembly requirements. It also requires minimal operator skill, is easy to use, and facilitates rework, resulting in a high product qualification rate and meeting product performance requirements.

[0038] In the above technical solution, the fixing buckle 2 and the oil storage barrel 1 are detachably assembled with each other, and the oil storage barrel 1 and the oil tank 3 can be locked or unlocked by pushing the fixing buckle 2 up and down to adjust the installation height.

[0039] Furthermore, the oil storage barrel 1 is provided with barrel fixing ribs 13 on both sides of the mounting groove 16 , and the barrel fixing ribs 13 cover the front of both sides of the fixing buckle 2 , and the barrel fixing ribs 13 are used to prevent the fixing buckle 2 from falling out of the mounting groove 16 forward.

[0040] During installation, the fixing buckle 2 is first installed with the oil storage barrel 1. The fixing buckle 2 passes through the barrel avoidance groove 15 of the oil storage barrel 1 from bottom to top and is pushed upward under the oil storage barrel 1 for installation. The barrel fixing ribs 13 cover both sides of the fixing buckle 2 to prevent the fixing buckle 2 from falling off. The barrel fixing ribs 13 to the installation surface height of 5.2mm are clearance-matched with the thickness of 5mm of the fixing buckle 2. At the same time, a process fillet is provided at the installation end of the fixing buckle 2 for easy installation. When pushing, the buckle elastic rib 23 of the fixing buckle 2 is affected by the barrel limit rib 1 of the oil storage barrel 1. 4. The buckle elastic rib 23 bends inward without affecting the pushing operation. After being pushed into place, the buckle elastic rib 23 pops outward and interferes with the barrel limiting circular rib 14 to limit the downward movement of the fixed buckle 2. At the same time, the barrel limiting hook 12 of the oil storage barrel 1 and the buckle limiting groove 22 of the fixed buckle 2 interlock with each other, limiting the upward and downward movement of the fixed buckle 2 and keeping the fixed buckle 2 in the unlocked state. When locking with the fuel tank is required, the fixed buckle 2 is pressed downward again, causing the barrel limiting hook 12 to disengage the buckle limiting groove 22 and reach the buckle upper notch 27. This design is compact and rational, meeting the product's performance requirements.

[0041] In the present invention, a buckle push-pull convex plate 21 protruding forward is integrally formed on the fixing buckle. The protruding buckle push-pull convex plate 21 is 14.7 mm long and 8.4 mm wide, which increases the contact area when pressed down and facilitates locking. A buckle limit slot 25 is provided on the rear side of the buckle push-pull convex plate 21, and the oil storage barrel 1 is provided with a barrel limit buckle 11 in the installation groove 16. The barrel limit buckle 11 is used to be inserted into the buckle limit slot 25, and a buckle avoidance groove 26 is also provided on the rear side of the fixing buckle 2 at the lower side of the buckle limit slot 25.

[0042] The forward-facing push-pull tab 21 provides a clear gripping point for the operator, facilitating the lifting or lowering of the retaining tab 2. Lifting the retaining tab 2 slides it into the unlocked position, while pressing it down slides it into the locked position. In the locked position, the barrel limiter clip 11 is located within the clip limiter slot 25; in the unlocked position, the barrel limiter clip 11 is located within the clip avoidance groove 26, which does not affect installation. The 13.6mm internal distance between the barrel limiter hooks 12 on either side creates an interference fit with the 14.7mm width of the retaining tab 2, ensuring a secure installation. The 13.6mm internal distance between the barrel limiter hooks 12 on either side creates a clearance fit with the 13.2mm width of the clip limiter grooves 22 on either side, and bevels are provided on the clip limiter grooves 22 and the front end for easy installation. Each time the oil tank 3 is installed or removed from the oil storage barrel 1, the tank limiter hooks 31 will contact and retract against the barrel limiter rib 14. Therefore, bevels are provided on the upper and lower outer sides of the barrel limiter rib 14 to facilitate installation. The design is compact and reasonable, meeting the working performance requirements of the product.

[0043] The retaining clip 2 is made of POM copolymer material, which offers excellent dimensional stability, high surface hardness, self-lubrication, friction resistance, and excellent electrical insulation. It is resistant to a variety of conventional fuel media, including methanol gasoline, ethanol gasoline, and regular gasoline, and maintains considerable chemical stability at high temperatures. It is well suited to the complex operating environment within the vehicle's fuel tank 3. The injection-molded retaining clip 22 provides secure installation and meets all operational and installation requirements.

[0044] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
