Description

Technical Field

[0001] This utility model relates to the field of gasoline pump technology, specifically a gasoline pump assembly. Background Technology

[0002] The fuel pump assembly is a core component of a car's fuel system, responsible for delivering fuel from the fuel tank to the engine and ensuring stable fuel pressure to meet injection requirements. Modern vehicles typically use electric fuel pump assemblies, which are integrated inside the fuel tank. Existing electric fuel pump assemblies mainly consist of a fuel cup, an electric fuel pump, a fuel pump bracket, a fuel level sensor, and connecting pipes.

[0003] Traditional fuel pump assemblies typically consist of a fuel cup, a fuel pump, and a mounting bracket. The fuel pump is directly fixed to the bottom or side wall of the fuel cup via a rigid bracket. During installation, it is crucial to ensure that the spacing between the fuel pump and the columns on the inner wall of the fuel cup matches; otherwise, a customized bracket structure is required. While fuel pump brackets fix the pump position by welding or bolts, the fit between the bracket and the fuel cup depends on pre-designed dimensions. Therefore, a fuel pump mounting solution that also allows for adaptive spacing is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a gasoline pump assembly that solves the problem that the gasoline pump bracket cannot be self-adjusting.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a gasoline pump assembly, including a fuel cup, three columns on the inner bottom surface of the fuel cup, a fuel pump inside the fuel cup, a support sleeve on the outer side of the fuel pump, a connector for connecting to the columns on the periphery of the support, and a spring installed on the bottom surface of the fuel pump. The installation height of the connector is adjustable.

[0007] Furthermore, the support includes a ring seat fitted around the outside of the oil pump, and multiple connectors are installed on the outer surface of the ring seat.

[0008] Furthermore, the connector includes a support arm fixed to the outer surface of the ring seat, the end of the support arm is connected to a sliding rod, an elongated groove is formed on the outer surface of the column, the sliding rod is fitted inside the column, and the support arm moves along the elongated groove.

[0009] Furthermore, both ends of the ring seat are provided with multiple extension plates, which are attached to the outer surface of the oil pump.

[0010] Furthermore, the bottom end of the slide rod is provided with a chamfered structure, the top end of the slide rod is provided with a deep groove, and the top end of the slide rod is provided with a screw hole, in which a screw is fitted and installed. The screw, when screwed in, pushes the top end of the slide rod to expand outward.

[0011] Furthermore, a through groove is provided on the outer surface of the slide rod, and the end of the support arm is inserted into the through groove.

[0012] Furthermore, the top of the oil cup is provided with a cover, and the oil cup and the cover are connected by a rod. A hose is connected to the cover, and the other end of the hose is connected to the oil pump.

[0013] This utility model has the following beneficial effects:

[0014] This utility model, through the adjustable support arm and through groove design, allows the installation position of the oil pump to be flexibly adjusted according to the different spacing of the three columns in the oil cup, and the length of the support arm extending into the through groove can be adjusted accordingly, eliminating the need for customized brackets and improving versatility.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 As shown, this utility model is a gasoline pump assembly, including a fuel cup 1, three columns 101 are provided on the inner bottom surface of the fuel cup 1, a fuel pump 2 is provided inside the fuel cup 1, a support 3 is sleeved on the outer side of the fuel pump 2, and a connector connected to the columns 101 is provided on the periphery of the support 3. A spring 7 is installed on the bottom surface of the fuel pump 2, wherein the installation height of the connector is adjustable.

[0028] During installation, the oil pump 2 placed inside the oil cup 1 is supported by the spring 7, and the position of the oil pump 2 is fixed by the support 3. The installation position of the oil pump 2 is changed by changing the fixed position of the support 3.

[0029] Among them, support 3 is made of polyethylene or polypropylene.

[0030] The support 3 includes a ring seat 301 sleeved on the outside of the oil pump 2. Multiple connectors are installed on the outer surface of the ring seat 301. Screws can also be installed on the ring seat 301 to fix the ring seat 301 to the outside of the oil pump 2.

[0031] The connector includes a support arm 303 fixed to the outer side of the ring seat 301. A slide rod 304 is connected to the end of the support arm 303. A long groove 102 is opened on the outer side of the column 101. The slide rod 304 fits in the column 101, and the support arm 303 moves along the long groove 102.

[0032] The movement range of the support arm 303 is limited by the long groove 102, thereby limiting the movement range of the support 3.

[0033] Both ends of the ring seat 301 are provided with multiple extension plates 302. The extension plates 302 are attached to the outer side of the oil pump 2. The ring seat 301, the extension plates 302 and the support arm 303 are an integral structure.

[0034] Two annular grooves are provided on the outer side of the oil pump 2, and a protruding rib is provided on the inner side end of the extension plate 302. The protruding rib is limited and fitted in the annular groove to solve the problem of the oil pump 2 slipping out of the annular seat 301 after installation.

[0035] The bottom end of the slide rod 304 is provided with a chamfered structure, the top end of the slide rod 304 is provided with a deep groove 3042, the top end of the slide rod 304 is provided with a screw hole, and a screw 305 is installed in the screw hole. The screw 305, when screwed in, pushes the top end of the slide rod 304 to expand outward.

[0036] The slide bar 304 is made of polyethylene or polypropylene. The chamfered structure of the slide bar 304 facilitates the insertion of the bottom end into the column 101. The tail of the screw 305 is a frustum structure. As the screw 305 is screwed in, the screw 305 pushes the end with the deep groove 3042 to expand outward. The top of the expanded slide bar 304 is fixed in the column 101.

[0037] A through groove 3041 is provided on the outer side of the slide bar 304, and the end of the support arm 303 is inserted into the through groove 3041.

[0038] The adjustable support arm 303 and the through groove 3041 are designed to fit together, so that the installation position of the oil pump 2 can be flexibly adjusted according to the different spacing of the three columns 101 in the oil cup 1. The length of the support arm extending into the through groove can adapt to a spacing tolerance of ±10mm, eliminating the need for a customized bracket and improving versatility.

[0039] The length of the support arm 303 extending into the through groove 3041 is adjusted according to the distance between the three columns 101 and the center of the oil pump 2;

[0040] It can adapt to different installation requirements of the spacing of the columns 101. In addition, the adjustable installation position of the slide bar 304 reduces the requirements for the machining accuracy of the parts. At the same time, by replacing the slide bar 304 of different sizes, the installation requirements of different columns 101 can be met.

[0041] The central angle between two adjacent support arms 303 is 120°, and the central angle between two adjacent columns 101 is 120°.

[0042] The top of the oil cup 1 is provided with a cover 4. The oil cup 1 and the cover 4 are connected by a rod 5. A hose 6 is connected to the cover 4, and the other end of the hose 6 is connected to the oil pump 2.
