Description

Technical Field

[0001] This utility model relates to the field of electronic oil pump technology, specifically to an automotive electronic oil pump connector. Background Technology

[0002] The electronic oil pump uses electricity as its power source. A motor drives the rotor to rotate, creating a vacuum at the inlet of the impeller, which draws in fuel or lubricating oil. After pressurization, the oil is then expelled from the outlet and supplied to the system. During operation, a pressure sensor monitors the outlet pressure and feeds the signal back to the control system. By adjusting the motor speed or the opening of the impeller blades inside the pump, the pressure and flow rate of the fuel or lubricating oil are precisely controlled to meet the needs of different operating conditions.

[0003] A search revealed that patent application number 201821742857.0 discloses an automotive electronic oil pump connector. It includes an insulating hose containing a twisted pair of wires. The twisted pair branches into two strands at both ends. One end of each twisted pair is connected to a pair of first terminals. A wiring mold is fitted around the outer side of the first terminals. The wiring mold is hollow and includes a mold body. A pair of hooks are provided on the front side of the mold body, and the rear ends of the hooks are connected to the two sides of the front end of the mold body. The advantages of this invention are: an axial sealing structure between the connector housing and the terminals; a small diameter at the cable seal outlet significantly improves the sealing reliability and provides good waterproof performance; a large diameter at the twisted pair outlet facilitates compatibility with various connector specifications; and the wiring mold is equipped with handles and barbs for easy manual disassembly and assembly, as well as for fixing to other workpieces.

[0004] The connectors in the aforementioned application documents are electrical connectors. However, in actual use, not only electrical connections are required, but more importantly, oil circuit connections are needed. Oil hoses need to be connected between the oil tank, electronic oil pump, and supply system. Existing hoses and end pipes are assembled with clamps, which has poor sealing performance and is prone to falling off after long-term use.

[0005] Therefore, we propose an automotive electronic oil pump connector. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an automotive electronic oil pump connector that solves the problem of limited sealing performance and the need to improve the connection effect of existing oil pipe clamp-type connections.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an automotive electronic oil pump connector, including an oil tank and a supply system, and an electronic oil pump for connecting them;

[0008] The input and output ends of the electronic oil pump, the input end of the supply system, and the output end of the oil tank are all equipped with end pipes, and the ends of the oil delivery pipes clamped between adjacent end pipes are pressed together by a limiting component.

[0009] As a preferred embodiment of this utility model, the oil delivery pipe is a flexible hose made of fluororubber, and the radius of the oil delivery pipe is the same as the radius of the end pipe.

[0010] The use of fluororubber in the oil pipeline offers excellent resistance to high temperatures and chemical corrosion, enabling it to adapt to higher operating temperatures and harsher environments, making it highly practical. Furthermore, the identical radius specifications of the oil pipeline and the end pipe ensure that the outer end of the oil pipeline is tightly fitted onto the end sleeve at the outer end of the end pipe, guaranteeing a secure fit.

[0011] As a preferred embodiment of the present invention, the limiting component includes a sleeve that is movably fitted on the outside of the end pipe and a clamp on its end. The clamp is located on the outside of the end sleeve, and the inner side of the oil pipe end is press-fitted between the end sleeve and the clamp.

[0012] The design of the clamp and end sleeve shapes allows for the pressing of the inner side of the oil pipeline end between them during the backward movement, ensuring the sealing of the oil pipeline connection.

[0013] As a preferred embodiment of this utility model, a bearing ring is provided at the left end of the sleeve, a screw sleeve is fixedly installed on the outer wall of the bearing ring, and the end head of the oil delivery pipe is also press-fitted between the sleeve and the outer wall of the end pipe.

[0014] The ferrule design allows the end of the oil pipe to be pressed between itself and the outer wall of the end pipe during lateral movement, further ensuring a tight seal during connection.

[0015] As a preferred embodiment of this utility model, the outer wall of the end tube is provided with a threaded portion, the inner side of the screw sleeve is provided with an internal threaded portion, and the screw sleeve is threadedly fitted onto the threaded portion.

[0016] The rotation of the screw sleeve can squeeze the clamp and ferrule outward, and press the oil pipe end head between them and the outer wall of the end pipe and the end sleeve, ensuring the connection effect and sealing performance, and preventing the oil pipe end head from falling off after long-term use.

[0017] In a preferred embodiment of this utility model, the output end of the oil tank is connected to the input end of the electronic oil pump, and the output end of the electronic oil pump is connected to the input end of the supply system via an oil delivery pipe.

[0018] The oil pipeline is designed to generate negative pressure through the end pipe, which draws oil from the tank and forces it into the supply system, ensuring efficient oil delivery.

[0019] This utility model provides an automotive electronic fuel pump connector. It has the following advantages:

[0020] This automotive electronic oil pump connector, through a press-fit design between the end of the end pipe and the oil pipe, utilizes the rotation of the threaded sleeve in the limiting component to compress the clamp and sleeve outward, pressing the end of the oil pipe between itself, the outer wall of the end pipe, and the end sleeve. This ensures the press-fit sealing and connection effect at the oil pipe connection, solving the problem of limited sealing performance and the need to improve the connection effect of existing oil pipe clamp-fit ​​connections.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 Figure 1-4 This utility model provides a technical solution: an automotive electronic oil pump connector, including an oil tank and a supply system, and an electronic oil pump 1 for connecting them; the input and output ends of the electronic oil pump 1, the input end of the supply system and the output end of the oil tank are all provided with end pipes 2, and the ends of the oil delivery pipes 3 clamped between adjacent end pipes 2 are press-fitted by limiting components 4.

[0028] The automotive electronic oil pump connector, through the press-fit setting between the end of the end tube 2 and the oil pipe 3, can utilize the rotation of the screw sleeve 44 in the limiting component 4 to squeeze the clamp 41 and the sleeve 42 outward, press-fitting the end of the oil pipe 3 between itself, the outer wall of the end tube 2, and the end sleeve 21, ensuring the press-fit sealing and connection effect at the connection of the oil pipe 3, and solving the problem of limited sealing performance and the need to improve the connection effect of the existing oil pipe clamp-fit ​​connection.

[0029] The oil pipeline 3 is a flexible hose made of fluororubber, and the radius of the oil pipeline 3 is the same as that of the end pipe 2. The fluororubber material of the oil pipeline 3 has excellent high temperature resistance and chemical corrosion resistance, and can adapt to higher working temperatures and harsh environments, making it highly practical. The fact that the oil pipeline 3 and the end pipe 2 have the same radius ensures that the outer end of the oil pipeline 3 is tightly fitted onto the end sleeve 21 at the outer end of the end pipe 2, guaranteeing a tight fit.

[0030] The limiting component 4 includes a retaining sleeve 42 that is movably fitted on the outside of the end pipe 2 and a clamp 41 at its end. The clamp 41 is located on the outside of the end sleeve 21, and the inner side of the end of the oil pipe 3 is pressed between the end sleeve 21 and the clamp 41. The shape of the clamp 41 and the end sleeve 21 allows the inner side of the end of the oil pipe 3 to be pressed between them during their backward movement, ensuring the connection and sealing of the oil pipe 3.

[0031] A bearing ring 43 is provided at the left end of the ferrule 42. A threaded sleeve 44 is fixedly installed on the outer wall of the bearing ring 43, and the end of the oil pipe 3 is also pressed between the clamp 41 and the outer wall of the end pipe 2. The ferrule 42 can press the end of the oil pipe 3 between itself and the outer wall of the end pipe 2 during the lateral movement, further ensuring the sealing effect during connection.

[0032] The outer wall of the end pipe 2 is provided with a threaded part 22, and the inner side of the screw sleeve 44 is provided with an internal threaded part, and the screw sleeve 44 is threadedly fitted onto the threaded part 22; wherein, the rotation of the screw sleeve 44 can squeeze the clamp 41 and the ferrule 42 outward, and press them between the end pipe 2 outer wall and the end sleeve 21 to press the end of the oil pipe 3, ensuring the connection effect and sealing performance, and preventing the end of the oil pipe 3 from falling off after long-term use.

[0033] The output end of the oil tank is connected to the input end of the electronic oil pump 1, and the output end of the electronic oil pump 1 is connected to the input end of the supply system through the oil delivery pipe 3. The oil delivery pipe 3 is designed so that the negative pressure generated by the end pipe 2 can draw the oil in the oil tank and force it out to the supply system, thus ensuring the oil delivery effect.

[0034] The working principle and usage process of this utility model are as follows: When the device is working, the oil supply pipe 3 needs to be connected between the output end of the oil tank and the input end of the electronic oil pump 1, and between the output end of the electronic oil pump 1 and the input end of the supply system. The end of the oil supply pipe 3 is enlarged and clamped and fitted onto the outside of the end pipe 2. Then, the limiting component 4 on the end pipe 2 is rotated so that the clamp 41 and the sleeve 42 on it move laterally, pressing the end of the oil supply pipe 3 between the outer wall of the end pipe 2 and the end sleeve 21, ensuring the sealing and connection effect of the oil supply pipe 3 and the end of the end pipe 2. This solves the problem that the sealing effect of the existing clamped connection of oil pipe is limited and the connection effect needs to be improved.
