Description

Technical Field

[0001] This utility model relates to an improved invention of a fuel pump, and more particularly to an improved invention of a reinforced fuel pump assembly bracket. Background Technology

[0002] Traditional fuel pump assembly brackets are mostly made of metal. The high density of metal brackets (such as steel or aluminum alloy) makes the entire fuel pump system bulky, increasing fuel consumption and emissions. In the trend towards lightweight vehicles, this does not meet environmental requirements and affects vehicle dynamic performance. Furthermore, moisture or corrosive substances in the fuel environment can easily cause metal oxidation, leading to bracket corrosion, which may result in: Decreased structural strength increases the risk of fracture; rust contaminates the fuel system, affecting fuel pump life and engine performance; maintenance costs increase, requiring frequent component replacement; the high rigidity of metal materials makes it easy to transmit engine vibrations to the fuel pump assembly, which can cause: amplified noise, fatigue damage to components, and shortened assembly life, especially on bumpy roads or at high speeds, and potential safety hazards, such as loose connections leading to fuel leaks.

[0003] The plastic support structure is simple and lacks reinforcement, making it prone to deformation under thermal expansion and contraction or vibration, resulting in unstable connection between the top cover and the fuel tank assembly. Specific impacts include: decreased sealing, potentially causing fuel leakage or evaporative emissions; low installation accuracy, increasing assembly time and error rate; reduced overall reliability; and frequent repairs, increasing costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a lightweight, high-strength fuel pump assembly bracket.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the reinforced fuel pump assembly bracket includes a bracket body, which is connected and supported between the top cover and the fuel tank assembly. The bracket body is characterized in that: the bracket body is integrally injection molded, the bracket body has mesh reinforcing ribs distributed on both sides, a quick-installation structure is provided between the top of the bracket body and the top cover, and an elastic connection structure is provided between the bottom of the bracket body and the fuel tank assembly.

[0006] The main body of the support is made of polyoxymethylene.

[0007] The quick-installation structure consists of buckles and sliding grooves located at the top of the bracket body and the bottom of the top cover, respectively.

[0008] The elastic connection structure includes a hook disposed at the bottom of the support body, a spring sleeved on the lower section of the support body, and a hanging interface disposed on the oil storage tank assembly. The hook extends into the hanging interface and engages with it for limiting, while the spring provides elastic support between the hanging interface and the support body.

[0009] The middle part of the bracket body is set as a twisted section, the upper and lower sections of the bracket body are both vertical sections, the upper section of the bracket body is connected to the middle of the top cover, and the lower section of the bracket body is connected to the upper outer ring of the oil storage tank assembly.

[0010] The thickness of the mesh reinforcing ribs is 1.2 to 1.5 times the thickness of the main body of the support.

[0011] The beneficial effects of this utility model are that the improved reinforced fuel pump assembly bracket has a 45% lighter weight than the metal solution, a 50% higher installation accuracy, a 50% higher efficiency, a more than 40% higher structural strength, a 2-3 times longer service life, and a 15dB lower noise level. It has the advantages of being lightweight, high-strength, and easy to install. Attached Figure Description

[0018] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-5 The reinforced fuel pump assembly bracket includes a bracket body 1, which is connected and supported between the top cover 2 and the fuel tank assembly 3. The bracket body 1 is integrally injection molded, and mesh reinforcing ribs 4 are distributed on both sides of the bracket body 1 to form a three-dimensional reinforcing rib structure. A quick-installation structure 5 is provided between the top of the bracket body 1 and the top cover 2, which can be quickly assembled without tooling, improving efficiency and reducing costs. An elastic connection structure is provided between the bottom of the bracket body 1 and the fuel tank assembly 3 to reduce vibration and noise.

[0019] As a further improved implementation, the material of the bracket body 1 is polyoxymethylene, which balances strength while improving fuel corrosion resistance.

[0020] As a further improved specific implementation, the quick installation structure 5 consists of a buckle and a sliding groove respectively located at the top of the bracket body 1 and the lower end of the top cover 2. The buckle and the sliding groove are connected to each other to achieve quick assembly.

[0021] As a further improved embodiment, the elastic connection structure includes a hook 7 disposed at the bottom of the support body 1, a spring 8 sleeved on the lower section of the support body 1, and a hanging interface 9 disposed on the oil storage tank assembly 3. The hook 7 extends into the hanging interface 9 and engages with it for limiting. The spring 8 elastically supports the hanging interface between the support body 1 and the support body 1. A limiting step is provided in the hanging interface 9 and on the support body 1. When vibration occurs, the support body 1 can compress the spring 8 to extend into the hanging interface 9 to eliminate vibration damage, and the spring 8 will return to its original position. The hook 7 will then hook onto the hanging interface 9 in the opposite direction for limiting.

[0022] As a further improved specific implementation, the middle part of the support body 1 is set as a twisted section 6, the upper and lower sections of the support body 1 are both vertical sections, the upper section of the support body 1 is connected to the middle of the top cover 2, and the lower section of the support body 1 is connected to the upper outer ring of the oil storage tank assembly 3. The shape of the support body 1 is reasonably designed to improve the stability of the support for the top cover 2 and effectively avoid oil outlet pipes, wiring, etc.

[0023] As a further improved implementation, the thickness of the mesh reinforcing rib 4 is 1.2 to 1.5 times the thickness of the support body 1, ensuring structural strength and stability.

[0024] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
