Description

Technical Field

[0001] The utility model relates to the technical field of electronic control units, in particular to an ECU main drain device. Background Art

[0002] In today's automotive industry, the electronic control unit (abbreviation: ECU, full name: Electronic Control Unit), also widely known as the vehicle computer or in-vehicle computer, has become an indispensable electronic heart of modern vehicles. As the comprehensive control center of the engine, the ECU always plays a key role. It continuously receives and analyzes diversified data from various parts of the vehicle, including human control information such as brake operations and gearshift commands, as well as dynamic parameters during vehicle operation, such as acceleration status, tire slip conditions, and fuel consumption rate. Based on preset precise algorithms, the ECU deeply processes this data and outputs precise control parameters to relevant actuators accordingly, ensuring the coordinated operation of all parts of the vehicle and optimizing its performance.

[0003] In the current technology, after the ECU of some vehicle models is installed, the main harness runs higher than the ECU plug. When passing through the cleaning line, water is likely to accumulate in the main body, and even water flows back along the main line to the ECU plug, thus causing the ECU plug to be soaked in water and resulting in the ECU being damaged by water ingress and ablation.

[0004] The disclosure of the above background art content is only used to assist in understanding the concept and technical solution of the present utility model, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background art should not be used to evaluate the novelty and inventiveness of this application. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an ECU main drain device to solve the technical problem in the above prior art that water flows back along the ECU main line to the ECU plug, thereby causing the ECU plug to be soaked in water and further resulting in the ECU being damaged by water ingress and ablation.

[0006] To this end, the present utility model provides an ECU main drain device.

[0007] Preferably, the present utility model may also have the following technical features:

[0008] An ECU main drain device includes a first elbow, a second elbow, a connecting pipe and a support plate. The first elbow and the second elbow are nearly in a "Z" shape, where the second elbow is in an inverted "Z" shape. The position of the first elbow is not higher than the wiring harness of the ECU main. The left end of the connecting pipe is connected to the right end of the first elbow, and the right end of the connecting pipe is connected to the left end of the second elbow, forming a nearly "U" shaped pipe. The connecting pipe is located at the lowest point of the nearly "U" shaped pipe, and a drain port is provided at the bottom of the connecting pipe. The right side of the nearly "U" shaped pipe is higher than the left side. The wiring harness of the ECU main enters from the left side of the nearly "U" shaped pipe and exits from its right side to dock with other plugins of the device. The support plate is in an inverted "Z" shape, with its first end at the lower left side connected to the engine block and its second end at the upper right side connected to the first elbow for supporting the first elbow.

[0009] Preferably, the support plate is made of a metal material with a certain hardness and a certain thickness.

[0010] Preferably, the support plate is made of stainless steel or steel.

[0011] Preferably, it further includes several saddle clamps. The saddle clamps are arranged on the first elbow and are connected to the second end of the support plate by bolts.

[0012] Preferably, the first elbow and the second elbow are made of flexible pipes, and the joints are sealed by winding with adhesive tape or pouring glue.

[0013] Preferably, the connecting pipe is made of a plastic with a certain hardness.

[0014] Preferably, the connecting pipe is one of a tee pipe, a straight pipe with a drain port, and a bent pipe with a drain port.

[0015] The beneficial effects of the present utility model compared with the prior art include: The ECU main drain device involved in the present utility model is provided with a first elbow, a second elbow, a connecting pipe and a support plate outside the wiring harness of the ECU main. The connecting pipe is arranged between the first elbow and the second elbow to form a nearly "U" shaped pipe. By setting the connecting pipe at the lowest point of the nearly "U" shaped pipe and providing a drain port at the bottom of the connecting pipe, the water on both sides of the connecting pipe can flow towards the drain port and be discharged, which can prevent the water on the ECU main wiring harness from flowing back to the plugin, effectively avoiding the problem of the ECU being burned due to being soaked in water. A support plate is arranged on the first elbow to fix the first elbow, making the drainage effect of the drain device better and improving the structural stability of the device.

[0020] An ECU trunk drain device, such as Figure 1 As shown, it includes a first elbow 1, a second elbow 2, a connecting pipe 3 and a support plate 4, the first elbow 1 and the second elbow 2 are nearly "Z"-shaped, wherein the second pipe 2 is in an inverted "Z" shape, the position of the first elbow 1 is not higher than the wiring harness 5 of the ECU trunk, the left end of the connecting pipe 3 is connected to the right end of the first elbow 1, and the right end of the connecting pipe 3 is connected to the left end of the second elbow 2 to form a nearly "U"-shaped pipeline, the connecting pipe 3 is located at the lowest point of the nearly "U"-shaped pipeline, and a drain port 31 is provided at the bottom of the connecting pipe 3, the right side of the nearly "U"-shaped pipeline is higher than the left side, the wiring harness 5 of the ECU trunk enters from the left side of the nearly "U"-shaped pipeline, passes through from the right side, and docks with other plug-ins of the device; the support plate 4 is in an inverted "Z" shape, the first end of its lower left side is connected to the engine body 6, and the second end of its upper right side is connected to the first elbow 1, for supporting the first elbow 1. The drainage device is provided with a nearly "U"-shaped pipe outside the wiring harness 5 of the ECU trunk and at a position not higher than the wiring harness 5, and a drainage port is provided on the connecting pipe 3 at the lowest point of the "U"-shaped pipe, so that water on the wiring harness 5 of the ECU trunk can flow out from the drainage port 31, which can effectively prevent the ECU from being ablated by water bubbles, and can also prevent water from flowing through the wiring harness 5 of the ECU trunk to other plug-ins of the equipment, thereby preventing the machine from colliding due to water ingress.

[0021] Specifically, the support plate 4 is made of a metal material with a certain hardness and a certain thickness. The metal material here can be stainless steel or steel, so that the support plate 4 has a certain thickness, enabling it to better support the first elbow 1, avoiding the shaking of the wire harness 5 at the first elbow 1, and improving the stability of the drainage device. A number of saddle clamps can be used to fix the support plate 4 to the first elbow 1. Specifically, the saddle clamps are arranged on the first elbow 1 and connected to the second end of the support plate 4 by bolts.

In this case, the wire harness 5 of the ECU main trunk can be first wound together with a corrugated pipe, then passed through the first elbow 1, through the connecting pipe 3, and finally passed out through the second elbow 2. The combination of the first elbow 1, the second elbow 2 and the connecting pipe 3 can also slow down the weathering and aging of the wire harness 5 and prevent impurities from entering between the wire harnesses 5.

[0023] Specifically, the connecting pipe 3 is made of a plastic material with a certain hardness, which can be materials such as PVC (polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene) and PP (polypropylene). The connecting pipe 3 can be one of a tee pipe, a straight pipe with a drain port and a bent pipe with a drain port, as long as the drain port 31 is at the bottom of the connecting pipe 3 and can play a drainage role, and the specific structure is not limited.
