1. A method for adjusting a strap of a virtual reality (VR) device, wherein the VR device comprises a VR main body and a VR strap adjustment mechanism, wherein the VR strap adjustment mechanism comprises a first strap and a second strap that are connected to the VR main body, a transmission component, a driver, a tightening trigger, a pressure sensor, a printed circuit board (PCB) electrically connected to the driver, the tightening trigger, and the pressure sensor, and a loosening trigger electrically connected to the PCB, wherein the driver is configured to drive the first strap and the second strap through the transmission component;
wherein the method for adjusting the strap comprises a method for tightening the strap, wherein the method for tightening the strap comprises:
obtaining, by the tightening trigger, a tightening trigger signal;
controlling, by the PCB, the driver to drive the transmission component based on the tightening trigger signal in such a manner that the first strap and the second strap are driven to be tightened synchronously;
obtaining, by the loosening trigger, a loosening trigger signal;
controlling, by the PCB, the driver to reversely drive the transmission component based on the loosening trigger signal in such a manner that the first strap and the second strap are driven to be loosened synchronously;
obtaining, by the pressure sensor, a pressure value at a preset part;
when the pressure value obtained by the pressure sensor reaches a first preset pressure value, controlling, by the PCB, the driver to stop driving the transmission component based on a first preset pressure value signal obtained by the pressure sensor in such a manner that the first strap and the second strap are synchronously tightened to an appropriate position; and
a second preset pressure value is zero, when the pressure value obtained by the pressure sensor reaches the second preset pressure value, controlling, by the PCB, the driver to stop reversely driving the transmission component based on a second preset pressure value signal obtained by the pressure sensor in such a manner that the first strap and the second strap stop loosening.
