Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a power distribution circuit board for new energy vehicles. Background Technology

[0002] Traditional circuit boards are fixed by drilling holes in the board material and using screws. This method is not only troublesome to install and disassemble, but also causes the circuit board to have poor solder joints or even be damaged due to the vibration generated when the new energy vehicle is running. At the same time, the circuit board generates a lot of heat when the car is running. If it cannot be dissipated in time, it will greatly shorten the service life of the circuit board.

[0003] Chinese patent CN114684036B discloses a protective circuit board for new energy vehicles, including a housing, a circuit board body, a liquid cooling head, and a radiator cover. A shock-absorbing seat is movably inserted into the bottom of the housing. Sleeves are fixedly connected to the left and right end walls of the housing. A pressure rod is movably inserted into the sleeve. A clamping plate is fixedly connected to the end of the pressure rod away from the sleeve. The circuit board body is fixedly clamped between the two clamping plates. A liquid cooling head is fixedly connected to the top of the circuit board body. A radiator cover is fixedly connected to the top of the housing. Multiple fixing plates are fixedly connected inside the radiator cover. Circulating heat dissipation pipes are fixedly clamped inside the fixing plates. Second sealing connectors are fixedly connected to the left and right sides of the bottom of the radiator cover. A wind-cooled protective shell is fixedly connected to the top of the radiator cover. Two air ducts are fixedly connected to the top of the wind-cooled protective shell. An exhaust fan is fixedly connected to the output end of the drive motor. This protective circuit board is easy to install and disassemble, effectively reduces vibration damage, and provides efficient heat dissipation for the circuit board.

[0004] The shortcomings of the above-mentioned existing technical solutions are that the fixing effect of fixing the circuit board body by clamping is poor when fixing spliced ​​circuit boards with multi-layer design, and there is still room for improvement in terms of practicality.
