Driving recorder electronics
A driving recorder captures information such as video and sound while a vehicle is on the road. Recording the driving process can provide evidence for traffic incidents, and can also document self-driving journeys and the negotiation of difficult routes.
The PCB is a core component of the driving recorder. This board design addresses the mounting of the recorder motherboard, with attention to removal and reinstallation during maintenance.
DVR PCB assembly and procurement
- Provide the PCB fabrication files and parts list for the project.
- PCB fabrication and circuit-board component procurement are included in the manufacturing scope.

PCB mounting design for a driving recorder
- A support rod is fixed to the inner bottom wall of the housing, with a tray fixed to the rod. The rod passes through a motherboard opening whose inner wall has an arcuate groove. A telescopic slot on the left side of the support rod contains a spring fixed to the slot’s right inner wall. The spring’s other end connects to a locating pin, which engages the arcuate groove. A ring groove at the top of the support rod holds a movable slider. An arcuate rod is fixed to the top of that slider, with its lower face overlapping the motherboard surface.
- Two brackets are fixed to the inner bottom wall of the housing.
- A limiting seat is fixed to the top of each bracket. The seats engage the motherboard’s lower-left and lower-right corners.
- A slot on the lower face of the motherboard engages a retaining piece fixed to the upper face of the tray.
- The left end of the locating pin has an arcuate profile.
