Description

Power control devices for electronic devices and vehicles

[0001] The present embodiment relates to an electronic device and a power control device for a vehicle.

[0002]

[0003] The most common electronic devices in automobiles are engine electrical devices (starter, ignition, charging) and lighting devices, but recently, as vehicles have become more electronically controlled, most systems, including chassis electrical devices, are becoming more electronic.

[0004] Recently, with the development of the information technology industry, various new technologies (motorized power steering, the Internet, etc.) aimed at increasing the convenience of automobiles are being incorporated into vehicles, and it is expected that the development of new technologies that can make the most of the current automobile systems will continue in the future.

[0005] Various electronic devices installed in automobiles, such as lamps, audio, heaters, and air conditioners, are supplied with power from the battery when the automobile is stopped and from the generator when the automobile is running. In this case, the power generation capacity of the 14V power system is used as the normal power voltage.

[0006] An electronic device may include a housing and a printed circuit board disposed within the housing, wherein a plurality of electronic components for driving the electronic device are disposed on the printed circuit board. In addition, the electronic device may receive or provide power from an external component, and accordingly may include a connector for power connection to the external component. The external power provided from the connector may be transmitted to the printed circuit board, and in this case, a fuse is provided between the connector and the printed circuit board to prevent overcurrent flow.

[0007] Electronic devices according to the prior art have a sub-printed circuit board that is distinct from the printed circuit board in order to secure a fuse placement area, and have adopted a method of connecting the printed circuit board and the sub-printed circuit board through a bus bar. However, there is a problem in that the manufacturing cost increases due to additional components, and production efficiency decreases due to an increase in assembly work.

[0008] Meanwhile, electronic devices include a housing and numerous electronic components arranged within it. Since electronic components generate heat as they operate, heat dissipation structures are essential considerations. For example, electronic devices may include refrigerant pipes, which can dissipate heat from the electronic components to the outside via the refrigerant flowing within them.

[0009] Meanwhile, although the refrigerant pipe can be placed at least partially on the surface of the housing, there is a problem that the manufacturing cost increases and production efficiency decreases due to increased assembly work, as welding is performed to secure the refrigerant pipe to the surface of the housing or additional parts are required to secure the refrigerant pipe.

[0010] An eco-friendly vehicle includes an on-board charger (OBC) that receives grid power from an external charging facility and converts it into direct current power for charging a battery, a converter that converts the voltage provided from the on-board charger into a low voltage and provides it to an electric load, and a battery that is charged with the power provided from the on-board charger.

[0011] Conventional vehicle power systems have problems in that the number of components increases and it is difficult to secure sufficient space for component placement within the vehicle, as the onboard charger (OBC), converter, charging module, and control module are each implemented as separate devices.

[0012]

[0013] The present embodiment provides an electronic device that can lower the manufacturing cost by reducing the number of parts and improve production efficiency by improving assembly.

[0014] In addition, the purpose is to provide an electronic device in which the refrigerant pipe can be fixed to the surface of the housing through a clamp, and the clamp can be compatible with various sizes of the refrigerant pipe.

[0015] In addition, the present invention provides a vehicle power control device that can reduce the number of components compared to conventional devices and secure a wider space for component placement within a vehicle by arranging components related to charging of a vehicle battery, power conversion, and power control within a single housing.

[0016]

[0017] An electronic device according to the present embodiment comprises: a housing; a printed circuit board disposed within the housing; a connection line disposed within the housing; and a fuse assembly disposed on the printed circuit board, wherein the fuse assembly comprises: a bracket disposed on the printed circuit board; a first bus bar disposed on the bracket and coupled to the connection line; a second bus bar disposed on the bracket to be spaced apart from the first bus bar in a second direction (Y) and coupled to the printed circuit board; and a fuse having both ends coupled to the first bus bar and the second bus bar.

[0018] The first bus bar may include a first plate portion coupled with the connecting line; a second plate portion bent from one side of the first plate portion and extending downward; a third plate portion bent from a lower end of the second plate portion and extending downward; and a first connecting portion including a plurality of first guide plates protruding upward from the third plate portion and having one end of the fuse coupled therebetween.

[0019] The second bus bar may include a fourth plate portion; a fifth plate portion that is bent and extends downward from one side of the fourth plate portion; a sixth plate portion that is bent and extends from a lower end of the fifth plate portion; and a second connecting portion that includes a plurality of second guide plates that protrude upward from the sixth plate portion and between which the other end of the fuse is connected.

[0020] The upper surface of the bracket includes a central portion and an edge portion arranged on the outer side of the central portion, and a first joining groove to which the third plate portion is joined and a second joining groove to which the sixth plate portion is joined may be formed in the central portion.

[0021] In the central portion, a first compartment that divides the first coupling groove from another area and a second compartment that divides the second coupling groove from another area may be arranged.

[0022] The above edge portion includes a first edge on which the first bus bar is arranged, and a second edge opposite the first edge on which the second bus bar is arranged, and a third joining groove to which the first plate portion is joined may be formed on an upper surface of the first edge, and a fourth joining groove to which the fourth plate portion is joined may be formed on an upper surface of the second edge.

[0023] A terminal extending downward from the fourth board portion and coupled to the printed circuit board may be provided, and a terminal to which the terminal is coupled may be arranged on the upper surface of the printed circuit board.

[0024] The above bracket includes a body and a plurality of leg portions protruding downward from the body, and a first element is arranged on the printed circuit board, and the first element can be arranged to overlap the body in a vertical direction.

[0025] A first catch portion may be arranged on the inner surface of the first compartment, and a second catch portion may be arranged on the inner surface of the second compartment.

[0026] The above fuses are provided in multiple numbers and arranged to be spaced apart from each other, and the first bus bar and the second bus bar can be provided in multiple numbers corresponding to the number of the fuses.

[0027]

[0028] In this embodiment, the fuse placement area is secured through the bracket, and the electrical connection structure of the fuse is implemented through the bus bar, so that the structure is simpler than the connection structure through the conventional sub-printed circuit board, and thus the component placement space within the housing can be secured more widely, and production efficiency can be improved due to improved assembly.

[0029] In addition, since the refrigerant pipe can be fixed to the surface of the housing through a clamp, there is an advantage in that the assembly process can be made simpler by omitting processes such as welding.

[0030] In addition, since the size of the joining area of ​​the refrigerant pipe can be adjusted by rotating the second body relative to the first body according to the size of the refrigerant pipe, there is an advantage in that it can be compatible with refrigerant pipes of various sizes.

[0031] In addition, since components related to charging the vehicle battery, power conversion, and power control are provided together in a single housing, the number of parts can be reduced compared to conventional systems, and there is an advantage in that the space for arranging parts within the vehicle can be secured more widely.

[0130] When the refrigerant pipe (1200) has a second diameter larger than the first diameter, the clamp (1300) can be adjusted so that the protrusion (1392) is positioned in the second hole (1343) within the adjustment hole (1341). Accordingly, a space (S2) having a second size larger than the first size in which the refrigerant pipe (1200) is arranged can be formed between the first coupling portion (1330) and the second coupling portion (1380).

[0131] When the refrigerant pipe (1200) has a third diameter larger than the second diameter, the clamp (1300) can be adjusted so that the protrusion (1392) is positioned in the third hole (1344) within the adjustment hole (1341). Accordingly, a space (S3) having a third size larger than the second size in which the refrigerant pipe (1200) is arranged can be formed between the first coupling portion (1330) and the second coupling portion (1380).

[0132] According to the structure as described above, the refrigerant pipe can be fixed to the surface of the housing through a clamp, so there is an advantage in that processes such as welding are omitted, making the assembly process simpler.

[0133] In addition, since the size of the joining area of ​​the refrigerant pipe can be adjusted by rotating the second body relative to the first body according to the size of the refrigerant pipe, there is an advantage in that it can be compatible with refrigerant pipes of various sizes.

[0161] Below, the operation of the vehicle power control device (30) according to an embodiment of the present invention will be described.

[0162] High voltage AC power can be provided to the vehicle power control device (30) through the first connector (2610). The AC power provided to the vehicle power control device (30) can pass through the EMC filter (2200) and be provided to the power conversion module (2500). The AC power provided to the power conversion module (2500) can be converted into high voltage DC power through the first electronic component (2520) within the power conversion module (2500).

[0163] The high voltage DC power converted through the first electronic component (2520) can charge the first battery in the vehicle through the BEM (2400) and the third connector (2630).

[0164] Additionally, the high voltage DC power converted through the first electronic component (2520) can be provided to the first load and the second load through the fuse (2570), the fourth connector (2650), and the fifth connector (2660).

[0165] In addition, the high-voltage DC power converted through the first electronic component (2520) can be converted into low-voltage DC power through the second electronic component (2550). The low-voltage DC power converted through the second electronic component (2550) can charge the second battery through the sixth connector (2670).

[0166] Meanwhile, as described above, charging of the first battery can be performed more quickly by transmitting DC power provided from the second connector (2620) through the BEM (2400) and the third connector (2630) in addition to the converted power through the power conversion module (2500).

[0167] According to the above structure, since components related to charging, power conversion, and power control of the vehicle's battery are all provided within a single housing, the number of components can be reduced compared to conventional systems, and there is an advantage in that the space for arranging components within the vehicle can be secured more widely.
