Description

Technical Field

[0001] This utility model relates to a fuel pump assembly, specifically a fuel pump mounting structure for a fuel pump assembly. Background Technology

[0002] In a fuel supply system, the fuel pump assembly, as a core component, is typically installed inside the fuel tank. Its structural design plays a crucial role in the efficiency and stability of fuel delivery. The fuel pump assembly generally includes components such as a fuel reservoir, fuel pump, injection pump, filter, pressure valve, fuel level sensor, and check valve. The fuel pump assembly draws fuel from the fuel tank and continuously delivers it to the engine through the fuel supply lines.

[0003] The fuel pump needs to be fixed inside the fuel reservoir. The connection method is as follows: multiple extended connecting arms protrude from the upper side wall of the fuel pump, and the outer end of the connecting arms is provided with a locking groove. The upper outer wall of the fuel reservoir has a number of buckles equal to the number of locking grooves. After the buckles are engaged with the locking grooves, the two are connected together. However, this connection method has a problem when disassembly is required. When separating, the outer end of the fuel pump connecting arm must be forcefully bent at a certain angle to separate the buckles from the locking grooves. Only in this way can the fuel pump be separated from the fuel reservoir. However, the connecting arm is easy to break when it is bent. If it breaks, the entire fuel pump housing will not function properly. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a fuel pump mounting structure for a fuel pump assembly.

[0005] The technical solution of this utility model is: a fuel pump mounting structure for a fuel pump assembly, including a fuel pump and a fuel tank. Multiple connecting arms protrude from the upper side wall of the fuel pump. Each connecting arm includes a connecting frame and a fixing clip. Each fixing clip has a snap-fit ​​groove on its outer side. The upper outer wall of the fuel tank has snap-fits equal in number to the snap-fit ​​grooves. The snap-fits engage with the snap-fit ​​grooves. One end of the connecting frame is fixed to the outer wall of the fuel pump, and the other end of the connecting frame has a sleeve with an insertion hole. One end of the fixing clip has a rod that inserts into the insertion hole of the sleeve and is detachably connected to the sleeve. A locking mechanism is installed on the upper end of the sleeve, including a locking rod for locking the rod.

[0006] Furthermore, the locking mechanism also includes a button and a spring. The middle part of the button is hinged to the upper end of the sleeve via a first pin. A second pin is rotatably connected to the upper end of the locking rod. The second pin is fixed to one end of the button, and the spring is locked between the other end of the button and the upper end of the sleeve.

[0007] Furthermore, the upper end of the insert has a first through hole that runs vertically through the locking rod, and the upper end of the insert has a second through hole that runs vertically through the locking rod, with the second through hole located directly below the first through hole.

[0008] Furthermore, when the button is pressed, the button rotates, causing the locking rod to move upwards and exit the second through hole.

[0009] The fuel pump mounting structure of the fuel pump assembly provided by this utility model has the following advantages: after pressing the button, the locking rod will separate from the second through hole of the insert rod. After the insert rod is freed from the restraint of the locking rod, it can be moved out of the insert hole. The fixing clip can be removed by pulling it outward, thereby separating the fuel pump from the fuel tank. It is not necessary to forcefully pry open the connecting arm of the fuel pump, and the connecting arm is not easily damaged. Attached Figure Description

Detailed Implementation

[0015] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0016] like Figure 1 — Figure 4As shown, a fuel pump assembly includes a fuel pump 1 and a fuel tank 2. Multiple connecting arms 3 protrude from the upper side wall of the fuel pump 1. Each connecting arm 3 includes a connecting frame 31 and a fixing clip 32. Each fixing clip 32 has a snap groove 321 on its outer side. The upper outer wall of the fuel tank 2 has a number of snap fasteners 21 equal to the number of snap grooves 321. The snap fasteners 21 snap into the snap grooves 321. One end of the connecting frame 31 is fixed to the outer wall of the fuel pump 1, and the other end of the connecting frame 31 has a sleeve 311 with a insertion hole 3111 inside. One end of the fixing clip 32 has a rod 322, which is inserted into the insertion hole 3111 of the sleeve 311 and detachably connected to the sleeve 311. A locking mechanism is installed at the upper end of the sleeve 311, including a locking rod 4 for locking the rod 322.

[0017] like Figure 3 As shown, the locking mechanism also includes a button 5 and a spring 6. The middle part of the button 5 is hinged to the upper end of the sleeve 311 via a first pin 7. A second pin 8 is rotatably connected to the upper end of the locking rod 4. The second pin 8 is fixed to one end of the button 5, and the spring 6 is engaged between the other end of the button 5 and the upper end of the sleeve 311. When the button 5 is pressed, the spring 6 is compressed. When the button 5 is released, the button 5 returns to its original position due to the elastic force of the spring 6.

[0018] like Figure 3 As shown, in order to facilitate the up and down movement of the locking rod 4, the upper end of the insert 311 has a first through hole 3112 that is vertically through and allows the locking rod 4 to pass through, and the upper end of the insert 322 has a second through hole 3221 that is vertically through and allows the locking rod 4 to pass through. The second through hole 3221 is located directly below the first through hole 3112.

[0019] When button 5 is pressed, button 5 rotates, and button 5 drives the locking rod 4 to move upward, and the locking rod 4 moves out of the second through hole 3221.

[0020] After pressing button 5, the locking lever 4 will separate from the second through hole 3221 of the insert lever 322. Once the insert lever 322 is freed from the locking lever 4, it can be moved out of the insertion hole 3111. Pulling the retaining clip 32 outwards will remove it, thus separating the fuel pump 1 from the fuel reservoir 2. There is no need to forcefully pry open the connecting arm 3 of the fuel pump 1, as the connecting arm 3 is less likely to be damaged. Figure 3 As shown, when the right end of button 5 is pressed down, the left end of button 5 will lift up, thereby causing the locking lever 4 to move upward.

[0021] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
