Bow and arrow auxiliary aiming equipment

Abstract

The invention discloses bow and arrow auxiliary aiming equipment. A corresponding table of the draw length and the shooting speed of a bow and arrow is obtained and input into a processor; the targetdistance between the bow and arrow and a target sheet is input into the processor through a first knob type potentiometer, the arrow flight time is obtained through calculation in combination with thearrow shooting speed, and the arrow falling height is obtained through the flight time and the gravitational acceleration; the processor calculates to obtain a theoretical shooting angle according tothe falling height and the target distance, calculates to obtain an initial pitch angle error of the bow and arrow according to the ratio of the difference value between the height of a target centerpoint and the height of a nocking point to the target distance, and inputs the initial pitch angle error into the processor through the second knob type potentiometer, therefore an optimal shooting angle of the bow and arrow is obtained; and an acceleration sensor is used for obtaining static pitch angles of different holding positions of the bow and arrow, the processor calculates the differencevalue between the optimal shooting angle and the static pitch angles, and if the absolute value of the obtained difference value is smaller than or equal to an optimal releasing angle judgment value,a display module prompts an arrow shooter that the current position of the bow and arrow is an optimal releasing angle.

Description

technical field [0001] The invention relates to the technical field of bow and arrow, in particular to an auxiliary aiming device for bow and arrow. Background technique [0002] The traditional bow sight is fixed on the side of the bow handle by screws, and the aiming frame is extended to the front end of the bow handle. There are one or more pointers in the aiming frame (the pointers can be cross pointers, red dots or optical fibers) , used to refer to the point where the arrow falls after the arrow is shot. The vertical and horizontal positions of the pointer and the pitch angle can be fine-tuned to match different bows and different personal habits; Put the pointer on the yellow heart of the target paper and let it go, the arrow will shoot out to complete the archery action. [0003] Based on the structural characteristics of the traditional sight, when the human eye, the pointer and the target become a straight line, the direction of the arrow is uncertain, and slight ...
