[0002] The fuel pump is one of the basic components of the fuel injection system of an electronically fuel-injected vehicle. It is located inside the vehicle fuel tank and works when the vehicle starts and the engine is running. Its function is to suck fuel out of the fuel tank, pressurize it, and then transport it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure.

[0003] In the assembly production line of existing automotive products, the assembly operation is often carried out in a pipeline manner. To ensure the assembly production rhythm of the vehicle, the operation time of each work station is usually short, which may easily lead to accidental stepping or trampling by the operator during the operation. The oil pump joints of the vehicle fuel tank oil pump are mostly conventional plastic part joints without a protection mechanism above. After being accidentally stepped on or trampled by the operator, the oil pump joints may break and the oil pump may be scrapped. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide an automobile fuel tank with an oil pump joint protection bracket, which is used to solve the problem that in the assembly operation of automotive products in the prior art, accidental stepping or trampling by the operator causes the oil pump joint to break and the oil pump to be scrapped.

[0005] To achieve the above purpose and other related purposes, the present utility model provides an automobile fuel tank with an oil pump joint protection bracket, including a fuel tank body. An oil pump body is installed above the fuel tank body, and an oil pump joint is installed above the oil pump body. The oil pump joint is connected to an outlet pipe and a return pipe. An oil pump bracket is installed around the oil pump body, and a protection bracket is installed on the oil pump bracket. The protection bracket covers the oil pump joint; a plurality of clamping claws for clamping the outer peripheral wall of the oil pump bracket are arranged on the protection bracket. The clamping claw includes two clamping fingers arranged crosswise up and down, and the distance between the two clamping fingers is less than the thickness of the outer peripheral wall of the oil pump bracket.

[0006] Optionally, the periphery of the oil pump bracket is a circle with a plurality of notches, and one notch corresponds to one clamping claw.

[0007] Optionally, the inner sides of the two clamping fingers of one clamping claw are adjacent, and both clamping fingers are inclined upward from the outside to the inside.

[0008] Optionally, the clamping claw further includes a support arm; the upper end of the support arm is connected to the outer peripheral wall of the protection bracket, and the lower end of the support arm is connected to the clamping finger.

[0009] Optionally, the protection bracket is provided with weight-reducing holes.

[0010] Optionally, the oil pump bracket includes a chassis and a sealing bracket. The chassis is fixedly installed on the fuel tank body, and the sealing bracket is buckled on the chassis.

[0011] Optionally, a plurality of buckles are provided on the chassis, and a plurality of buckling grooves are correspondingly formed on the sealing bracket.

[0012] Optionally, the buckling groove is composed of a first buckling groove and a second buckling groove that communicate with each other. The width of the first buckling groove is greater than the width of the second buckling groove; the buckle includes a connecting arm and a buckling arm. The connecting arm connects the chassis and the buckling arm, and the width of the connecting arm is less than the width of the second buckling groove; the width of the buckling arm is between the width of the first buckling groove and the width of the second buckling groove.

[0013] Optionally, a buckling protrusion is provided on the upper surface of the sealing bracket. The buckling protrusion is connected to the second buckling groove; after the connecting arm enters the second buckling groove, the buckling arm cooperates with the buckling protrusion to lock the sealing bracket on the chassis.

[0014] Optionally, there are at least three clamping claws.

[0015] As described above, a motor vehicle fuel tank with an oil pump joint protection bracket of the present utility model has at least the following beneficial effects:

[0016] 1. In the motor vehicle fuel tank with an oil pump joint protection bracket, an oil pump bracket is installed around the oil pump body, and a protection bracket is installed on the oil pump bracket. The design that the protection bracket covers the oil pump joint protects the oil pump joint when the operator installs the fuel tank, avoiding damage to the oil pump joint caused by the operator's trampling; at the same time, a plurality of clamping claws for clamping the outer peripheral wall of the oil pump bracket are provided on the protection bracket. The clamping claws include two clamping fingers arranged crosswise up and down, and the distance between the two clamping fingers is less than the thickness of the outer peripheral wall of the oil pump bracket. When the operator installs the protection bracket, the outer peripheral wall of the oil pump bracket can be clamped by the two clamping fingers to achieve the purpose of stably installing the protection bracket. Compared with using methods such as bolt connection and welding, this design facilitates the overall installation of the fuel tank and subsequent maintenance of the fuel tank.

[0017] 2. The automotive fuel tank with an oil pump joint protection bracket has a circular shape with multiple notches on the periphery of the oil pump bracket. One notch corresponds to one jaw design. When the operator installs the protection bracket, he only needs to align the jaws with the notches first, and then turn the protection bracket clockwise or counterclockwise to screw the jaws away from the notch position. The two fingers of the jaws can then clamp the outer peripheral wall of the oil pump bracket. When the operator wants to remove the protection bracket, he only needs to turn the protection bracket until the jaws are aligned with the notches, and then the protection bracket can be removed. Whether it is installation or disassembly, it is very convenient for the operator. When meeting the condition of protecting the oil pump joint, it not only improves the production efficiency but also enhances the subsequent maintainability of this automotive fuel tank.

[0018] 3. The automotive fuel tank with an oil pump joint protection bracket has the inner sides of the two fingers of one jaw adjacent to each other, and both fingers are designed to tilt from the outside to the inside and upwards. When the jaw of the protection bracket is aligned with the notch on the oil pump bracket and then during the turning process, it can be turned more easily and can gradually tighten the protection bracket on the oil pump bracket, that is, during the process of turning the protection bracket, gradually let the two fingers of one jaw clamp the outer peripheral wall of the oil pump bracket; the process of removing the protection bracket is the opposite; compared with the design where the two fingers are horizontally arranged, this design is obviously more convenient for the operator's installation operation and disassembly operation.

[0019] 4. The automotive fuel tank with an oil pump joint protection bracket also includes a support arm for the jaw; the upper end of the support arm is connected to the outer peripheral wall of the protection bracket, and the lower end of the support arm is connected to the finger of the jaw. Compared with the design where the finger is directly connected to the protection bracket, it has higher stability, can support a greater weight, and has a better protection effect on the oil pump joint.

[0020] 5. The oil pump bracket of the automotive fuel tank with an oil pump joint protection bracket includes a bottom frame and a sealing frame. The bottom frame is fixedly installed on the fuel tank body, and the sealing frame is buckled on the bottom frame. This design not only provides a stable installation foundation for the protection bracket but also plays a role in stabilizing the oil pump body, reducing the possibility of oil leakage from the connection between the fuel tank body and the oil pump body.

[0029] The following individual embodiments are only for illustration purposes. Combinations can be made between the individual embodiments, and it is not limited to the content shown in the following single embodiment.

[0030] Please refer to Figure 1 , the present utility model provides an automotive fuel tank with an oil pump connector protection frame, including a fuel tank body 1. An oil pump body 3 is installed above the fuel tank body 1, and an oil pump connector 4 is installed above the oil pump body 3. The oil pump connector 4 is connected to an outlet pipe 5 and a return pipe 6. The above is the conventional design in the prior art. The different design point of this automotive fuel tank from the prior art is that an oil pump support 7 is installed around the oil pump body 3, and a protection frame 2 is installed on the oil pump support 7. The protection frame 2 covers the oil pump connector 4; when the operator installs the fuel tank, it plays a role in protecting the oil pump connector 4 and avoids the situation that the oil pump connector 4 is damaged due to the operator's trampling. That is, it solves the problem in the prior art that during the assembly operation of automotive products, the operator accidentally steps on or tramples on the oil pump connector 4, causing the oil pump connector 4 to break and the oil pump to be scrapped.

[0031] Such as Figure 2As shown, a plurality of jaws 21 for clamping the outer peripheral wall of the oil pump bracket 7 are provided on the protective frame 2. The jaw 21 includes two clamping fingers 211 arranged crosswise up and down, and the distance between the two clamping fingers 211 is less than the thickness of the outer peripheral wall of the oil pump bracket 7. When the operator installs the protective frame 2, the outer peripheral wall of the oil pump bracket 7 can be clamped by the two clamping fingers 211 to achieve the purpose of firmly installing the protective frame 2. Compared with the methods such as bolt connection and welding, this design facilitates the overall installation of the fuel tank and subsequent maintenance of the fuel tank.

[0032] In another embodiment, please refer to Figure 2 and Figure 4 , the periphery of the oil pump bracket 7 is a circle with a plurality of notches 724, and one notch 724 corresponds to one jaw 21. The technical solution adopted in this embodiment enables the operator to, when installing the protective frame 2, first align the jaw 21 with the notch 724, and then turn the protective frame 2 clockwise or counterclockwise to screw the jaw 21 away from the notch 724 position, and the two clamping fingers 211 of the jaw 21 can clamp the outer peripheral wall of the oil pump bracket 7; when the operator wants to remove the protective frame 2, as long as the protective frame 2 is turned until the jaw 21 is aligned with the notch 724, the protective frame 2 can be removed. Whether it is installation or disassembly, it is very convenient for the operator to operate. When the condition of protecting the oil pump joint 4 is met, it not only improves the production efficiency but also enhances the subsequent maintainability of this automotive fuel tank.

[0033] At the same time, the design of the notch 724 also facilitates the operator to use tools to perform other operations on the oil pump bracket 7 from the notch 724.

[0034] In another embodiment, please refer to Figure 2 and Figure 3 , the inner sides of the two clamping fingers 211 of one jaw 21 are adjacent, and both of the two clamping fingers 211 are inclined upward from the outside to the inside. When the operator aligns the jaw 21 of the protective frame 2 with the notch 724 on the oil pump bracket 7 and then turns it, it can be turned more easily, and the protective frame 2 can be gradually tightened on the oil pump bracket 7, that is, during the process of turning the protective frame 2, the two clamping fingers 211 of one jaw 21 are gradually tightened against the outer peripheral wall of the oil pump bracket 7; the reverse working process is for removing the protective frame 2; compared with the design where the two clamping fingers 211 are horizontally arranged, this design is obviously more convenient for the operator's installation and disassembly operations.

[0035] In another embodiment, please refer to Figure 2, the jaw 21 further includes a support arm 212; the upper end of the support arm 212 is connected to the outer peripheral wall of the protective frame 2, and the lower end of the support arm 212 is connected to the finger 211. The technical solution of this embodiment has higher stability compared with the design where the finger 211 is directly connected to the protective frame 2, can support a greater weight, and can play a good protective role for the oil pump joint 4 even if the stepped weight exceeds the conventional weight.

[0036] In another embodiment, please refer to Figure 2 , a weight-reducing hole is provided on the protective frame 2, which saves production materials while ensuring the function of the protective frame 2 to protect the oil pump joint 4.

[0037] In another embodiment, please refer to Figure 2 and Figure 4 , the oil pump bracket 7 includes a bottom frame 71 and a sealing frame 72. The bottom frame 71 is fixedly installed on the fuel tank body, and the sealing frame 72 is buckled on the bottom frame 71. The technical solution of this embodiment not only provides a stable installation foundation for the protective frame 2, but also plays a role in stabilizing the oil pump body 3, reducing the possibility of oil leakage from the connection between the fuel tank body and the oil pump body 3.

[0038] In another embodiment, please refer to Figure 2 , a plurality of buckles are provided on the bottom frame 71, and a plurality of buckling grooves are correspondingly provided on the sealing frame 72. The sealing frame 72 and the bottom frame 71 are buckled, which is more conducive to the installation and disassembly of the sealing frame 72 and enhances the maintainability of the automotive fuel tank.

[0039] In another embodiment, please refer to Figure 4 , the buckling groove is composed of a first buckling groove 721 and a second buckling groove 722 that are interconnected. The width of the first buckling groove 721 is greater than the width of the second buckling groove 722; the buckle includes a connecting arm 711 and a buckling arm 712. The connecting arm 711 connects the bottom frame 71 and the buckling arm 712, and the width of the connecting arm 711 is less than the width of the second buckling groove 722; the width of the buckling arm 712 is between the width of the first buckling groove 721 and the width of the second buckling groove 722. A buckling protrusion 723 is provided on the upper surface of the sealing frame 72, and the buckling protrusion 723 is connected to the second buckling groove 722. When the operator installs the sealing frame 72 on the bottom frame 71, first align the first buckling groove 721 with the buckle and put it down, then twist the sealing frame 72 to twist the second buckling groove 722 to the buckle. The buckling arm 712 and the buckling protrusion 723 cooperate to lock the sealing frame 72 on the bottom frame 71. The whole operation process is simple and clear, which is beneficial to improving production efficiency.

[0040] In other embodiments, there are at least three jaws 21, because three can ensure the stability of the protective bracket. Of course, as Figure 3As shown, in our actual production, a design with 4 such jaws 21 is adopted.

[0041] In summary, in this utility model, an oil pump bracket 7 is installed around the oil pump body 3, and a protective frame 2 is installed on the oil pump bracket 7. The design that the protective frame 2 covers the oil pump joint 4 plays a role in protecting the oil pump joint 4 when the operator installs the fuel tank, avoiding the situation that the oil pump joint 4 is damaged due to the operator's stepping on it; also, a plurality of jaws 21 for clamping the outer peripheral wall of the oil pump bracket 7 are provided on the protective frame 2. The jaw 21 includes two clamping fingers 211 arranged crosswise up and down, and the distance between the two clamping fingers 211 is less than the thickness of the outer peripheral wall of the oil pump bracket 7. When the operator installs the protective frame 2, the outer peripheral wall of the oil pump bracket 7 can be clamped by the two clamping fingers 211 to achieve the purpose of firmly installing the protective frame 2. Compared with using methods such as bolt connection and welding, this design facilitates the overall installation of the fuel tank and subsequent maintenance of the fuel tank; at the same time, the outer periphery of the oil pump bracket 7 is a circle provided with a plurality of notches 724, and one notch 724 corresponds to one jaw 21. When the operator installs the protective frame 2, only need to align the jaw 21 with the notch 724 first, and then turn the protective frame 2 clockwise or counterclockwise to screw the jaw 21 away from the notch 724 position, and the two clamping fingers 211 of the jaw 21 can clamp the outer peripheral wall of the oil pump bracket 7; when the operator wants to remove the protective frame 2, as long as the protective frame 2 is turned until the jaw 21 is aligned with the notch 724, the protective frame 2 can be removed. Whether it is installation or disassembly, it is very convenient for the operator to operate. When meeting the condition of protecting the oil pump joint 4, it not only improves production efficiency but also enhances the subsequent maintainability of this automotive fuel tank. Therefore, this utility model effectively overcomes the shortcomings in the prior art and has high industrial utilization value.
