Description

Technical Field

[0001] This utility model relates to the field of ECU housing technology, specifically a heat-dissipating and waterproof ECU housing. Background Technology

[0002] As modern automobiles continue to evolve towards intelligence and automation, the Electronic Control Unit (ECU) plays an increasingly crucial role. It is responsible for the precise control and adjustment of numerous automotive systems, such as the engine control system, transmission control system, and vehicle stability system, to ensure normal vehicle operation, performance optimization, and driving safety. Today, the number of ECUs in automobiles is constantly increasing, and their functions are becoming increasingly complex.

[0003] The ECU generates heat during operation. Existing ECUs use a waterproof and breathable membrane structure to mitigate the impact of airflow and effectively dissipate heat. However, these membranes are typically attached to the outer wall of the housing, and are prone to loosening under continuous airflow, thus affecting the ECU's operation. Therefore, we need a waterproof ECU housing that can dissipate heat. Utility Model Content

[0011] Preferably, the bearing spring is in a stretched state, and the disc is rotationally connected to the inner wall of the fixing block.

[0012] Preferably, the fixing block is provided with clamping grooves which are arranged in a circumferential array on the fixing block.

[0013] Preferably, the anti-impact mechanism comprises first and second notches which are arranged in a staggered manner in the interior of the shell.

[0014] Compared with the prior art, the waterproof ECU shell with heat dissipation has the following beneficial effects:

[0015] 1. The waterproof ECU shell with heat dissipation can drive the bent plate to rotate and reset through the elastic force of the torsion spring in the stabilizing mechanism, drive the rubber block on the outer wall through the bent plate to clamp and fix the outer wall of the waterproof and breathable film, prevent loosening of the waterproof and breathable film, and make the rubber block in a suspended state through clamping of the clamping teeth into the clamping grooves, so that the waterproof and breathable film is convenient to replace.

[0016] 2.

[0024] In the embodiment, firm mechanism 4 is provided on fixed block 3, the elastic force of torsion spring 44 in firm mechanism 4 can drive bent plate 42 to rotate reset, the rubber block 43 on the outer wall is driven by bent plate 42, which can clamp and fix the outer wall of waterproof air-permeable membrane 2, prevent the loosening of waterproof air-permeable membrane 2, and the rubber block 43 is in a suspended state by the clamping of the teeth 46 into the inside of the card slot 49, which is convenient for replacing waterproof air-permeable membrane 2.

[0025] In the embodiment, the inside of shell 1 is provided with anti-impact mechanism 5, by the staggered arrangement of first slot 51 and second slot 52, when waterproof air-permeable membrane 2 releases heat dissipation to airflow, the impact of airflow can be buffered, to prevent the impact of airflow from causing damage to waterproof air-permeable membrane 2 and affecting the service life of waterproof air-permeable membrane 2.

[0026] The above-mentioned firm mechanism 4 includes a rotating rod 41, which is rotatably connected to the inner wall of the fixed block 3. The outer wall of the rotating rod 41 is fixedly installed with a bent plate 42. The bent plate 42 is arranged in a bent shape. By pressing the end of the bent plate 42 around the rotating rod 41, the bent plate 42 can drive the rubber block 43 to release the clamping of the waterproof air-permeable membrane 2. The outer wall of the bent plate 42 is fixedly installed with a rubber block 43. The rubber block 43 is in a state of adhesion with the outer wall of the waterproof air-permeable membrane 2. The outer wall of the rotating rod 41 is fixedly connected with one end of a torsion spring 44. The other end of the torsion spring 44 is fixedly connected with the inner wall of the fixed block 3. The outer wall of the rotating rod 41 is slidably connected with a sleeve 45. The end of the sleeve 45 is provided with a tooth 46. The inner wall of the sleeve 45 is fixedly connected with one end of a bearing spring 47. The other end of the bearing spring 47 is fixedly connected with the outer wall of a disc 48. The bearing spring 47 is in a stretched state. The sleeve 45 can move towards the direction of the card slot 49 by the elastic force of the bearing spring 47. The disc 48 is rotatably connected with the inner wall of the fixed block 3. The fixed block 3 is provided with a card slot 49. The card slot 49 is distributed in a circular array on the fixed block 3. The sleeve 45 drives the tooth 46 to be clamped into the inside of the card slot 49, so that the sleeve 45 drives the rotating rod 41 to be unable to rotate.
