Abstract

The invention relates to a door hinge, a novel control circuit of an electric parking door hinge, a motor current sampling circuit, a current signal amplification module and a microprocessor I are sequentially connected, a power supply interface, a 5V voltage stabilizing circuit, and a 3.3V voltage stabilizing circuit Connect with microprocessor 1 successively, motor interface, DC motor drive circuit and microprocessor 1 are connected successively, wireless signal receiving module, wireless switch signal interface circuit and microprocessor 1 are connected successively, wired switch interface connects microprocessor 1; The wireless signal transmitting module, the microprocessor II, the rechargeable battery, the wireless charging receiving module, the wireless charging transmitting module, the power adapter, the backup charging power supply module and the power interface are connected in sequence, and the button switch is connected to the microprocessor II; the wireless signal transmitting module sends The signal can be received by the wireless signal receiving module; the structure of the control circuit is simple, and the position of the motor can be judged without adding additional sensors; the design of the peripheral circuit is simple, which can reduce the failure rate of the circuit.

Description

technical field [0001] The invention relates to a door hinge, in particular to a circuit for controlling a new type of electric parking door hinge. The hinge is driven by a tiny DC motor and can realize parking and self-locking at any time. control circuit. Background technique [0002] In our life, doors are everywhere, but in the process of using the door, sometimes it needs to be slightly opened, sometimes it needs to be half-opened, and sometimes it needs to be fully opened. As for how to position the door, after the door is opened, if it cannot be positioned properly, the door will be forced to close due to wind or collision, and sometimes the door will be damaged. The current solution on the market is to choose a door stopper, but On the one hand, the door stopper is only used for the fully open state of the door. On the other hand, during the installation process of the door stopper, it is necessary to punch holes on the door, or on the floor, or on the wall. , this...
