Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic control units, in particular to a low-position ECU waterproof device. Background Art
[0002] In today's automotive industry, the Electronic Control Unit (ECU), also known as the onboard computer or onboard computer, has become one of the indispensable electronic hearts of modern vehicles. As the engine's integrated control center, the ECU plays a critical role at all times, continuously receiving and analyzing diverse data from all parts of the vehicle. This data encompasses human control information such as braking operations and shift commands, as well as dynamic vehicle parameters such as acceleration status, tire slip, and fuel consumption. Based on pre-set sophisticated algorithms, the ECU deeply processes this data and outputs precise control parameters to the relevant actuators, ensuring coordinated operation and optimal performance of all vehicle components.
[0003] However, current automotive manufacturing technology designates the ECU for some models as being mounted relatively low on the engine's intake side, close to the wheels. While this placement has specific design considerations, it can pose safety risks in certain situations, particularly when driving on muddy roads or undergoing water-related operations such as car washes. The ECU's low position makes it susceptible to water intrusion, increasing the risk of internal ECU components ablating due to water intrusion. Such failures can not only severely impact the performance of the ECU itself but can also impact the vehicle's entire powertrain and driving safety.
[0004] In view of the above problems, the industry urgently needs a waterproof device for low-position ECUs to effectively cope with complex and changeable water environments, ensure that the ECU can operate stably under various conditions, and protect the overall performance and driving safety of the car.

[0023] The present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope and application of the present invention.
[0024] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically specified.
[0025] A low-position ECU waterproof device, such as Figure 1 and 2As shown, it includes an upper shell 1 and a lower shell 2. The lower end of the lower shell 2 is closed and embedded in the engine body 3. The upper part of the lower shell 2 protrudes from the engine body 3. The upper end of the lower shell 2 is open, which is a first opening. The ECU is placed into the lower shell through the first opening. The sides of the upper shell 1 are closed and arched. Making the sides closed can better prevent water from entering the ECU when the vehicle is wading, and the arched shape is more conducive to drainage. The upper shell 1 and the lower shell 2 are usually made of plastic. Making the sides of the upper shell 1 into an arc shape is easier to form and demold, reducing production costs. In some examples, the ECU may partially protrude from the first opening. The side shape of the upper shell 1 can be set to match the shape of the protruding part, thereby achieving minimized space occupation, compact structure and efficient space utilization. The lower end of the upper shell 1 is open, which is a second opening that matches the first opening. The lower end of the upper shell 1 is fitted with the upper end of the lower shell 2 and fixed with a number of connectors 4 to form a first space for accommodating the ECU to ensure the waterproof effect of the ECU; both the upper shell 1 and the lower shell 2 are provided with drain ports to drain water that enters the upper shell 1 and the lower shell 2. The ECU is placed in the first space and is wrapped by the upper shell 1 and the lower shell 2 to prevent water from entering the ECU to a large extent. In addition, due to the setting of the drain port, if the ECU accidentally enters water, the water that enters the upper shell 1 and the lower shell 2 can be quickly drained to prevent the ECU from being burned and extend its service life.
[0026] Specifically, if Figure 1 As shown, the drain port includes a first drain port 11 and a second drain port 21. The first drain port 11 is provided at the first end face of the upper shell 1, and the second drain port 21 is provided at a position on the upper portion of the lower shell 2 protruding from the engine body 3. It is understood that the wiring harness of the ECU extends from the first end face of the upper shell 1 (that is, the first drain port 11) to connect with other components of the vehicle. It is understood that appropriate waterproofing treatment, such as glue filling, should be done where the wiring harness extends. Specifically, depending on the different ECU settings of each vehicle model, in some examples, such as Figure 2 As shown, the upper shell is arranged vertically. In this case, the drain port 11 is the first drain port. In other examples, the upper portion of the lower shell 2 protruding from the engine body 3 includes a first side wall 22. The first side wall 22 is arranged at an angle to the engine body 3. Preferably, the first side wall 22 is arranged at a 90° angle to the engine body 3. The upper end of the first side wall 22 is the first opening, and the second drain port 21 is arranged on the first side wall 22. In other examples, such as Figure 1As shown, the upper portion of the lower shell 2 protruding from the engine body 3 also includes a first plane 23, and the first plane 23 is consistent with the setting direction of the engine body 3. The first space is below the first plane 23, and the lower end of the first side wall 22 is connected to the first plane 23. The second drain port 21 is arranged on the first side wall 22 and / or the first plane 23. In this example, the second drain port 21 is arranged on the first plane 23 and on the lower side of the upper shell 1. In order to improve the drainage effect, multiple second drain ports 21 can also be provided to more smoothly drain the water in the shell.
[0027] Specifically, the connecting member 4 can be a bolt, with a plurality of protrusions correspondingly provided at the lower end of the upper shell and the upper end of the lower shell, and mounting holes provided on the protrusions, and the bolts are used to connect the upper shell and the lower shell. In some examples, the connecting member can also be a buckle, which includes a male buckle and a female buckle, respectively provided at the lower end of the upper shell and the upper end of the lower shell. The buckle achieves a quick and stable connection and facilitates opening the upper shell for maintenance and other work.
