Description

Technical Field

[0001] This application relates to the field of ECU protection, and more specifically, to an ECU protective cover structure. Background Technology

[0002] The ECU, acting as the engine's brain, controls key parameters such as air intake and fuel injection. Some ECUs are directly mounted on the vehicle, while others are mounted on the engine itself, typically on the intake side, below the intake manifold. The diesel fuel filter is also mounted on the intake side, usually positioned higher up for easy filter replacement, with the filter's fuel line running directly above the ECU. This arrangement poses a risk. If the fuel filter or fuel line leaks, or if rainwater splashes in, oil or water can flow into the interface between the ECU and wiring harness, leading to signal transmission failures, ECU burnout, or even serious safety incidents such as fires. Therefore, we propose an ECU protective cover structure. Utility Model Content

[0003] To overcome the shortcomings of the existing system, this application provides an ECU protective cover structure that can solve the problem of the risk of oil droplets flowing to the interface.

[0004] The technical solution adopted by this application embodiment to solve its technical problem is: an ECU protective cover structure, including an ECU body installed on the engine, a lower protective shell detachably connected to the interface end of the ECU body, an upper protective shell detachably connected to the lower protective shell, a common wiring harness connector connecting one end of the lower protective shell and the upper protective shell, the wiring harness connector connecting to the engine wiring harness pipe, and a heat dissipation component connected to the side wall of the lower protective shell.

[0005] In one specific implementation, a first sealing ring is provided between the lower protective shell and the interface end of the ECU body, and a second sealing ring is provided between the lower protective shell and the upper protective shell.

[0006] In one specific implementation, the wiring harness connector includes a lower connector and an upper connector, which are respectively connected to the lower housing and the upper housing.

[0007] In one specific implementation, the same third sealing ring is installed in the lower connector and the upper connector, the engine wiring harness conduit is inserted into the lower connector and the upper connector, and the third sealing ring is fitted onto the engine wiring harness conduit.

[0008] In one specific implementation, the heat dissipation component includes a mounting tube that communicates with the lower housing, a cooling fan is installed inside the mounting tube, and an air inlet pipe is connected to one end of the mounting tube.

[0009] In one specific implementation, the air inlet pipe is L-shaped, with the inlet end facing downwards.

[0010] In one specific implementation, an air guide shroud is fixedly installed on the inner wall of the lower housing. The air guide shroud covers the outlet end of the mounting pipe. The air guide shroud is connected to one side wall of the ECU body. A plurality of air outlet holes are opened on one side wall of the ECU body, and the plurality of air outlet holes are all located inside the lower housing.

[0011] In one specific implementation, a through-hole is provided on one side wall of the ECU body, and the through-hole is located inside the air guide shroud.

[0012] The advantages of this embodiment are: by installing a lower protective shell on the interface end of the ECU body and an upper protective shell on the lower protective shell, the contact end of the ECU body is located inside the lower and upper protective shells, preventing oil and water from dripping onto the interface of the ECU body and affecting its use. The upper protective shell can be removed from the lower protective shell, which facilitates the maintenance of the internal ECU body interface. By installing a heat dissipation component on the side wall of the lower protective shell, heat dissipation can be achieved for the interface of the ECU body, thereby reducing the temperature of the wiring harness at the interface and ensuring that the wiring harness can be used normally.

Detailed Implementation

[0020] The technical solution in this application embodiment aims to address the risk of oil droplets flowing to the interface. The overall approach is as follows:

[0021] Example:

[0022] Please see Figure 1-6 An ECU protective cover structure includes an ECU body 10 mounted on an engine. Specifically, the mounting structure of the ECU body 10 is existing technology. A lower protective shell 20 is detachably connected to the interface end of the ECU body 10. The lower protective shell 20 is connected to the ECU body 10 via an existing snap-fit ​​structure. An upper protective shell 30 is detachably connected to the lower protective shell 20. Similarly, the upper protective shell 30 is connected to the lower protective shell 20 via a snap-fit ​​structure. One end of the lower protective shell 20 and the upper protective shell 30 is connected to the same wiring harness connector 40, which is connected to the engine wiring harness conduit. It should be noted that an engine wiring harness conduit is installed on the engine, allowing the engine wiring harness to pass through the engine wiring harness conduit, then through the wiring harness connector 40, and inserted into the lower protective shell 20, thereby connecting the engine wiring harness to the interface of the ECU body 10. A heat dissipation component 50 is connected to the side wall of the lower protective shell 20. The heat dissipation component 50 is used for heat dissipation inside the lower protective shell 20 to prevent the interface temperature of the ECU body 10 from becoming too high. Both the lower protective shell 20 and the upper protective shell 30 are made of plastic.

[0023] See Figure 5 A first sealing ring is provided between the lower housing 20 and the interface end of the ECU body 10, and a second sealing ring is provided between the lower housing 20 and the upper housing 30. Specifically, neither the first nor the second sealing ring is shown. By providing the first and second sealing rings, the sealing performance between the lower housing 20 and the outer wall of the ECU body 10, and between the lower housing 20 and the upper housing 30, is improved.

[0024] See Figure 5 The wiring harness connector 40 includes a lower connector 410 and an upper connector 420, which are respectively connected to the lower housing 20 and the upper housing 30. Specifically, the lower connector 410 can be closed with the upper connector 420, so that the engine wiring harness passes through the lower connector 410 and the upper connector 420. Furthermore, the same third sealing ring is installed in the lower connector 410 and the upper connector 420. The engine wiring harness conduit is inserted into the lower connector 410 and the upper connector 420, and the third sealing ring is fitted on the engine wiring harness conduit. Specifically, a lead tube is connected to the outer wall of the engine wiring harness conduit, and the lead tube is inserted into the wiring harness connector 40. At the same time, the third sealing ring is fitted on the lead tube to improve the sealing performance.

[0025] See Figure 1 and 5The heat dissipation component 50 includes a mounting pipe 510, which is connected to the lower housing 20. A cooling fan 520 is installed inside the mounting pipe 510. One end of the mounting pipe 510 is connected to an air inlet pipe 530. Specifically, when the cooling fan 520 operates, it causes air to flow inside the mounting pipe 510. The air flows into the lower housing 20 and then enters the engine wiring harness pipe through the wiring harness connector 40, thereby achieving air circulation. The engine wiring harness pipe has open ends, and the open ends are located away from the filter and oil pipe. Furthermore, the air inlet pipe 530 is L-shaped, with the inlet end facing downwards, which can prevent oil and water from entering the air inlet pipe 530.

[0026] See Figure 4-6 An air guide shroud 210 is fixedly installed on the inner wall of the lower housing 20. The air guide shroud 210 covers the outlet end of the mounting tube 510. The air guide shroud 210 is connected to one side wall of the ECU body 10. Several air outlets 110 are opened on one side wall of the ECU body 10. The air outlets 110 are all located inside the lower housing 20. Specifically, the air in the mounting tube 510 flows into the air guide shroud 210, so that the air can enter the ECU body 10 through the air guide shroud 210, and then be blown out into the lower housing 20 from the air outlets 110. This allows the air to flow through the interior of the ECU body 10, achieving the purpose of cooling the interior of the ECU body 10. A through-hole 120 is opened on one side wall of the ECU body 10. The through-hole 120 is located inside the air guide shroud 210. When set up, the air in the air guide shroud 210 enters the ECU body 10 through the through-hole 120.

[0027] When this application is used:

[0028] The lower housing 20 is installed on the side wall of the ECU body 10. The lower connector 410 is fitted onto the lead pipe of the engine wiring harness pipe, and the third sealing ring is fitted onto the engine wiring harness pipe. The engine wiring harness passes through the lower connector 410 and enters the lower housing 20. Then, the interface of the engine wiring harness and the ECU body 10 is connected. After that, the upper housing 30 can be connected to the lower housing 20. The upper connector 420 is fitted onto the lead pipe of the engine wiring harness pipe to achieve sealing protection of the interface end of the ECU body 10. During the operation of the ECU body 10, the cooling fan 520 works, allowing air to enter the air intake pipe 530, then through the mounting pipe 510 into the air guide shroud 210, and then into the ECU body 10 through the through-hole 120. Thus, several air outlets 110 blow air into the lower housing 20 and the upper housing 30, and then through the wiring harness connector 40 into the engine wiring harness pipe to achieve airflow and dissipate heat from the ECU body 10 and its contact points.

[0029] It should be noted that the specific model and specifications of the ECU body 10 and the cooling fan 520 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0030] The power supply and working principle of the ECU body 10 and the cooling fan 520 are clear to those skilled in the art, and will not be described in detail here.

[0031] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
