Description

Technical Field

[0001] This utility model relates to the field of automotive controller technology, and in particular to an ECU controller housing. Background Technology

[0002] With the continuous development of automotive technology, the Electronic Control Unit (ECU), as a core component of the automotive industry, is becoming increasingly important. An ECU is a microprocessor-based device that receives signals from various sensors, processes them, and then sends control commands to actuators to ensure that the engine and other automotive systems operate according to preset programs and parameters, achieving precise control over various automotive functions.

[0003] The ECU serves as the "brain" of a car. During operation, its internal chips and power devices continuously generate heat. Without a well-designed heat dissipation structure, this can lead to transistor energy drift and accelerated component aging. Currently, existing ECUs typically include a housing, a circuit board mounted inside the housing, and connectors mounted on the side of the housing. The connectors consist of a socket and a set of pins on the socket. The inner ends of the pins engage with the circuit board to achieve electrical connection. To ensure good heat dissipation performance for the ECU, the housing is usually made of aluminum, which has good heat dissipation properties. However, aluminum is expensive, resulting in high production costs and impacting the product's market competitiveness.

[0004] Therefore, it is necessary to design an ECU controller housing with good heat dissipation performance and lower cost to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ECU controller housing that not only has good heat dissipation performance, ensuring the stability of the ECU controller's operation, but also has lower production costs, which helps to enhance the product's market competitiveness.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ECU controller housing, including a base plate and a top cover mounted on the base plate, wherein a mounting cavity for accommodating a circuit board is formed between the top cover and the base plate; it also includes a heat sink, the heat sink being made of aluminum, the heat sink including a connecting base plate and multiple heat sinks, a mounting opening being provided through the top cover, the connecting base plate being detachably mounted on the mounting opening, and the multiple heat sinks being evenly distributed at equal intervals on the side of the connecting base plate away from the mounting cavity.

[0007] By adopting the above technical solution, only the core heat dissipation components are made of aluminum. Through the connection of the substrate to the exposed, evenly distributed heat sinks, the heat generated by the circuit board within the mounting cavity can be quickly conducted to the external environment. Furthermore, the large heat dissipation area and excellent heat dissipation effect are beneficial for the long-term stable operation of the ECU. More importantly, unlike all-aluminum housing designs on the market, only the heat dissipation components are made of aluminum; the base plate and top cover can be made of low-cost alloys, steel, or plastic. This significantly reduces the overall amount of aluminum used, effectively lowering production costs while meeting heat dissipation requirements, thus enhancing the product's market competitiveness.

[0008] The present invention is further configured such that the area of ​​the connecting substrate is larger than the area of ​​the mounting opening, and a quick-release plate is provided on each of the left and right sides of the connecting substrate. The quick-release plate is provided with a quick-release hole. Two elastic quick-release rods are installed on the inner side of the top cover. The elastic quick-release rods pass through the corresponding quick-release holes, and the lower end of the elastic quick-release rod is provided with an inverted conical locking part for locking the corresponding quick-release plate to the inner side of the top cover.

[0009] By adopting the above technical solution, the operator only needs to press the heat sink to the mounting port of the upper cover, and the elastic quick-release rod will automatically snap into the quick-release hole to complete the locking and fixing (the inverted conical locking part at the lower end of the elastic block rod forms an axial anti-dislodgement limit after the elastic quick-release rod snaps into the quick-release hole), without the need to tighten screws or add buckle accessories, making the assembly operation very convenient.

[0010] The present invention is further configured such that a cross-shaped partition is provided at the lower end of the inverted conical locking part along the axial direction, so that the inverted conical locking part forms four elastic barbs.

[0011] By adopting the above technical solution, during the process of the inverted conical locking part of the elastic quick-release rod engaging with the quick-release hole, the four independent elastic barbs can simultaneously retract inward until the elastic quick-release rod completely passes through the quick-release hole. Then, the four independent elastic barbs return outward and axially lock and fix the quick-release plate, making assembly easier and more convenient.

[0012] The present invention is further configured such that the upper end of the elastic quick-release rod is provided with a snap-fit ​​plate, and the inner side of the upper cover is provided with two snap-fit ​​seats. The snap-fit ​​seats have a slot for inserting the snap-fit ​​plate on the side away from the installation port, and the bottom of the snap-fit ​​seats has a clearance hole for sliding the corresponding elastic quick-release plate in.

[0013] By adopting the above technical solution, the detachable structure between the elastic quick-release rod and the top cover is not only easier to process, but also has strong structural maintainability. When the elastic quick-release rod is damaged, it can be replaced separately, saving maintenance costs.

[0014] The present invention is further provided that the inner wall of the slot of the card holder is provided with an elastic anti-loosening protrusion for restricting the card plate in the slot.

[0015] By adopting the above technical solution, the elastic anti-loosening protrusion restricts the position of the snap-fit ​​plate, keeping it always inside the socket, which greatly improves the stability of the snap-fit ​​plate installation.

[0016] The present invention is further provided that the upper end of the connecting substrate is provided with an annular recess near the outer edge, and an annular sealing ring is embedded in the annular recess for abutting against the inner side of the upper cover to form a seal.

[0017] By adopting the above technical solution, the annular sealing ring can not only provide dust and water protection, but also provide a vertical pre-tightening force for the connecting substrate, so as to make the inverted conical locking part firmly abut against the connecting substrate, thereby improving the stability of the heat sink installation.

[0018] The present invention is further provided that the inner side of the upper cover is provided with an annular flange for abutting against the upper end of the annular sealing ring.

[0019] By adopting the above technical solution, the contact stress between the top cover and the annular sealing ring can be increased, thereby further improving the sealing performance between the top cover and the connecting substrate.

[0020] The present invention is further configured to include two brackets respectively disposed on both sides of the base plate. Each bracket includes an integrally formed upper connecting plate, a bent plate, and a lower connecting plate. The height of the upper connecting plate is greater than the height of the lower connecting plate. The upper connecting plate, the base plate, and the upper cover are connected together by screws. The lower connecting plate is also provided with multiple mounting holes.

[0021] By adopting the above technical solution, not only is assembly convenient, but the bracket can also lift the entire shell, which not only adapts to the reserved installation space of different depths, but also increases the overall heat dissipation effect. Attached Figure Description

[0024] 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.

[0025] Example: As attached Figures 1-9 The ECU controller housing shown includes a base plate 1 and a top cover 2 mounted on the base plate 1. A mounting cavity 3 for accommodating a circuit board is formed between the top cover 2 and the base plate 1. The housing also includes a heat sink 4 made of aluminum. The heat sink 4 includes a connecting base plate 5 and multiple heat sinks 6. A mounting port 7 is provided through the top cover 2, and the connecting base plate 5 is detachably mounted on the mounting port 7. The multiple heat sinks 6 are evenly distributed at equal intervals on the side of the connecting base plate 5 away from the mounting cavity 3. In this embodiment, only the core heat dissipation component is made of aluminum. Through the evenly distributed heat sinks 6 on the exposed side of the connecting base plate 5, the heat generated by the circuit board in the mounting cavity 3 can be quickly conducted to the external environment. The large heat dissipation area and good heat dissipation effect are beneficial to the long-term stable operation of the ECU. More importantly, unlike all-aluminum housing designs on the market, only the heat sink 4 is made of aluminum. The base plate 1 and top cover 2 can be made of low-cost alloy, steel, or plastic materials, greatly reducing the overall amount of aluminum used. While meeting heat dissipation requirements, this effectively reduces the production cost of the product, which is beneficial to improving the product's market competitiveness.

[0026] As attached Figures 2-4 The area of ​​the connecting base plate 5 is larger than the area of ​​the mounting port 7, meaning the orthographic projection of the mounting port 7 is completely within the area of ​​the connecting base plate 5. A quick-release plate 8 is provided on each of the left and right sides of the connecting base plate 5, and a quick-release hole 9 is provided on the quick-release plate 8. Two elastic quick-release rods 10 are installed on the inner side of the upper cover 2. The elastic quick-release rods 10 pass through the corresponding quick-release holes 9, and the lower end of each elastic quick-release rod 10 has an inverted conical locking part 11 for locking the corresponding quick-release plate 8 to the inner side of the upper cover 2. The inverted conical locking part 11 and the quick-release rod are an integral structure. The operator only needs to press the heat sink 4 onto the mounting port 7 of the upper cover 2 to allow the elastic quick-release rod 10 to automatically engage with the quick-release hole 9 and complete the locking (the inverted conical locking part 11 at the lower end of the elastic block rod forms an axial anti-disengagement limit after the elastic quick-release rod 10 engages with the quick-release hole 9), eliminating the need for additional screws 26 or additional clip accessories, making assembly very convenient.

[0027] As attached Figure 7 As shown, the lower end of the inverted conical locking part 11 has a cross-shaped partition 12 along the axial direction, so that the inverted conical locking part 11 forms four elastic barbs 13, wherein the cross-shaped partition 12 extends to the upper part of the elastic quick-release rod 10. During the process of the inverted conical locking part 11 of the elastic quick-release rod 10 engaging with the quick-release hole 9, the four independent elastic barbs 13 can simultaneously retract inward until the elastic quick-release rod 10 completely passes through the quick-release hole 9, and the four independent elastic barbs 13 return to their original position and axially lock and fix the quick-release plate 8, making assembly easier and more convenient.

[0028] As attached Figure 7 and attached Figure 8 As shown, the upper end of the elastic quick-release rod 10 is also provided with a snap-fit ​​plate 14, and the inner side of the upper cover 2 is also provided with two snap-fit ​​seats 15. The snap-fit ​​seat 15 has a slot 16 for inserting the snap-fit ​​plate 14 on the side away from the mounting port 7. The opening of the slot 16 is set in the direction away from the mounting port 7. The bottom of the snap-fit ​​seat 15 is provided with a clearance hole 17 for the corresponding elastic quick-release plate 8 to slide into. The width of the clearance hole 17 is smaller than the width of the slot 16, and the width of the clearance hole 17 is approximately equal to the diameter of the elastic quick-release rod 10. The upper end of the quick-release plate 8 abuts against the lower end of the snap-fit ​​seat 15, and the lower end of the quick-release plate 8 abuts against the upper end of the inverted conical locking part 11. The detachable structure between the elastic quick-release rod 10 and the upper cover 2 not only makes processing more convenient, but also makes the structure more maintainable. When the elastic quick-release rod 10 is damaged, it can be replaced separately, saving maintenance costs.

[0029] As attached Figure 3As shown, the inner wall of the slot 16 of the connector 15 is provided with an elastic anti-loosening protrusion 18 for restricting the connector plate 14 within the slot 16. The elastic anti-loosening protrusion 18 is semi-ellipsoidal in shape. The elastic anti-loosening protrusion 18 restricts the position of the connector plate 14, keeping it always inside the socket, which greatly improves the stability of the connector plate 14 installation.

[0030] As attached Figure 3 and attached Figure 4 As shown, an annular recess 19 is provided at the upper end of the connecting base plate 5 near its outer edge. The annular recess 19 is formed by stamping, and an annular sealing ring 20 is embedded in the annular recess 19 to form a seal against the inner side of the upper cover 2. The annular sealing ring 20 not only provides dust and water protection, but also provides a vertical preload to the connecting base plate 5, causing the inverted conical locking part 11 to firmly abut against the connecting base plate 5, thereby improving the stability of the heat sink 4 installation.

[0031] As attached Figure 3 As shown, the inner side of the upper cover 2 is integrally provided with an annular flange 21 for abutting against the upper end of the annular sealing ring 20. This design can increase the contact stress between the upper cover 2 and the annular sealing ring 20, thereby further improving the sealing performance between the upper cover 2 and the connecting substrate 5.

[0032] As attached Figure 9 As shown, the housing also includes two brackets 22 respectively disposed on both sides of the base plate 1. Each bracket 22 includes an integrally formed upper connecting plate 23, a bent plate 24, and a lower connecting plate 25. The height of the upper connecting plate 23 is greater than the height of the lower connecting plate 25. The upper connecting plate 23, the base plate 1, and the upper cover 2 are connected together by screws 26. Specifically, the upper connecting plate and the base plate 1 are respectively provided with through holes for the screws 26 to pass through, and the upper cover 2 is provided with screw holes or screw sleeves for the screws 26 to be screwed in. The lower connecting plate 25 is also provided with multiple mounting holes 27. This design not only facilitates assembly, but also allows the brackets 22 to lift the entire housing, adapting to different depths of reserved installation space while also increasing the overall heat dissipation effect.
