Description

Technical Field

[0001] This utility model relates to the field of DC conversion equipment technology, specifically to a dual-output dual-DC converter control system. Background Technology

[0002] Currently, dual-output DC-DC converters are not widely used in the two-wheeled and three-wheeled vehicle market. Existing DC-DC converters are mostly single-output designs, making it difficult to simultaneously meet the needs of various electrical devices in the vehicle and the charging needs of users' mobile phones. Using multiple independent converters to supply power is not only cumbersome to install and requires a large amount of space, but also suffers from poor compatibility and high maintenance costs. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a dual-output DC-DC converter control system with high integration, reliable protection, efficient heat dissipation, flexible installation and strong safety.

[0004] The technical solution adopted by this utility model is as follows: This utility model provides a dual-output DC-DC converter control system, including a die-cast aluminum housing, a PCBA board, a power inductor, a 12V output interface, and a 5V output interface. The PCBA board is fixed inside the die-cast aluminum housing with bolts. A transistor switch is welded onto the PCBA board. The power inductor is welded onto the PCBA board. The 12V output interface is connected to the PCBA board through a first connecting line, and the 5V output interface is connected to the PCBA board through a second connecting line. Both sides of the die-cast aluminum housing are provided with cable outlet slots. The first connecting line and the second connecting line respectively pass through the cable outlet slots on both sides. Sealing plugs are provided in the cable outlet slots on both sides. The die-cast aluminum housing is filled with two-component epoxy resin to form a sealed protective layer.

[0005] Preferably, the die-cast aluminum shell is provided with a fixing lug, and the fixing lug is provided with a waist-shaped groove.

[0006] Preferably, the die-cast aluminum shell is provided with a high-pressure warning label pasting area.

[0007] Preferably, the die-cast aluminum shell is provided with heat dissipation fins.

[0008] Preferably, the bolt is an M3 bolt.

[0009] The beneficial effects of this utility model by adopting the above structure are as follows: This utility model adopts a dual-channel independent output design. The 12V output interface is adapted to the vehicle's conventional electrical equipment, and the 5V output interface is adapted to USB mobile phone charging, meeting the power needs of two-wheeled and three-wheeled vehicles in multiple scenarios. There is no need to equip multiple converters, simplifying the equipment layout.

[0010] The die-cast aluminum shell combines excellent heat dissipation performance and structural strength. Combined with internal two-component epoxy resin potting treatment, it forms double protection inside and out, effectively achieving rainproof, vibrationproof, waterproof, dustproof, and electromagnetic interference-resistant properties, significantly improving the product's stability and service life under complex working conditions.

[0011] The PCBA board is secured with M3 screws and connected to the main body of the equipment via fixing lugs on both sides, ensuring a stable installation and preventing loosening or displacement during equipment operation. It is connected to the main wiring harness of the vehicle via connecting sleeves, making disassembly and assembly convenient and highly interchangeable. Damaged individual parts can be replaced individually, reducing return rate and failure loss rate. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] like Figures 1-4 As shown, this utility model discloses a dual-output DC-DC converter control system, including a die-cast aluminum housing 1, a PCBA board 2, a power inductor 3, a 12V output interface, and a 5V output interface 5. The PCBA board 2 is fixed inside the die-cast aluminum housing 1 by bolts 7. A transistor switch 21 is soldered onto the PCBA board 2. The power inductor 3 is soldered onto the PCBA board 2. The 12V output interface is connected to the PCBA board 2 via a first connecting wire 41, and the 5V output interface 5 is connected to the PCBA board 2 via a second connecting wire 51. 2. Connection: Both sides of the die-cast aluminum housing 1 are provided with cable outlet grooves. The first connecting wire 41 and the second connecting wire 51 pass through the cable outlet grooves on both sides respectively. Both sides of the cable outlet groove are provided with sealing plugs 8. The die-cast aluminum housing 1 is filled with two-component epoxy resin 6 to form a sealing and protective layer. The die-cast aluminum housing 1 is provided with fixing lugs 12, and the fixing lugs 12 are provided with waist-shaped grooves 13. The die-cast aluminum housing 1 is provided with a high-voltage warning label pasting area 11. The die-cast aluminum housing 1 is provided with heat dissipation fins 14. The bolts 7 are M3 bolts.

[0017] In practical use, the device is fixed in the target position by using bolts 7 through the waist-shaped groove 13 of the fixing ear plate 12. The position is finely adjusted according to the installation requirements to ensure a stable installation. The external power supply is connected to the input pin of the PCBA board 2 (the connecting wire is led out from the reserved hole and arranged separately from the output wire). The 12V output interface 4 and the 5V output interface are connected to the corresponding external devices respectively. After the power is turned on, the transistor switch 21 on the PCBA board 2 and the power inductor 3 work together to convert the input voltage into a stable 12V and 5V DC voltage, which is output to the external device through the corresponding interface. The heat generated during the operation is conducted to the die-cast aluminum shell through the PCBA board 2, and then dissipated into the air through the heat sink fins 14. The sealed two-component epoxy resin glue 6 and the sealing plug 8 isolate external humidity and dust, protecting the internal components and ensuring stable operation.

[0018] In summary, this utility model adopts a dual-output independent design. The 12V output interface 4 is compatible with conventional vehicle electrical equipment, and the 5V output interface 5 is compatible with USB mobile phone charging, meeting the power needs of two-wheeled and three-wheeled vehicles in various scenarios without the need for multiple additional converters, thus simplifying the equipment layout. The die-cast aluminum shell combines excellent heat dissipation performance and structural strength. Combined with internal two-component epoxy resin potting treatment 6, it forms double protection, effectively achieving rainproof, vibration-proof, water-proof, dustproof, and electromagnetic interference-resistant properties, significantly improving the product's stability and service life under complex working conditions. The PCBA board 2 is fixed with M3 screws, and connected to the main body of the equipment with fixing lugs 12 on both sides, ensuring a stable installation and preventing loosening or displacement during equipment operation. It is connected to the vehicle's main wiring harness through connecting sleeves, making disassembly and assembly convenient and highly interchangeable. Damaged individual parts can be replaced individually, reducing return rates and failure loss rates.
