Toy Gun Trigger Linkage Mechanism for Pawl Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trigger linkage mechanisms in toy guns lack precise control over the rotation radius and speed of the pawl member, resulting in suboptimal firing speed and user experience due to the design of arc-shaped springs providing both vertical and horizontal elastic forces.
Innovation Solution
A trigger linkage mechanism featuring a push block, linkage member with an abutting part, pull member with a pawl part, and two recovery springs (helical and torsional) to control and adjust the rotation radius and speed of the pawl part, allowing for precise adjustment of the elastic coefficients and abutting part location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an arc-shaped spring is used to drive the pawl member, then the pawl member can be recovered when the trigger is released, but the rotation radian and speed of the pawl member cannot be precisely controlled
Solution Approach 1:
The single arc-shaped spring is divided into two separate recovery springs: a first recovery spring (helical spring) and a second recovery spring (torsion spring). Each spring independently controls different aspects of the pawl member's motion, enabling precise control over rotation radian and speed while maintaining reliable recovery function.
Solution Approach 2:
The invention changes the elastic force parameters by using two different spring types with distinct characteristics. The first recovery spring provides vertical elastic force while the second recovery spring provides horizontal elastic force, allowing independent adjustment of force parameters to precisely control rotation radian and speed.
2Power
If the arc-shaped spring provides both vertical and horizontal elastic forces, then the pawl member can be driven to rotate, but the firing speed and user experience are not optimal
Solution Approach 1:
The combined elastic force function is segmented into two independent spring systems. The first recovery spring handles vertical force requirements while the second recovery spring handles horizontal force requirements, allowing each spring to be optimized for its specific function and improving overall firing speed.
Solution Approach 2:
The invention introduces dynamic control by allowing independent adjustment of the two recovery springs' elastic coefficients. This enables optimization of the drive mechanism's dynamic characteristics to achieve better firing speed and user experience.

Function Achieved in This Case
This design enables precise control over the rotation radius and speed of the pawl part, enhancing firing speed and user experience by ensuring smooth pellet firing and preventing pellet obstruction between the magazine bore and gun barrel.
Implementation Method 1
a first recovery spring clamped between the gun frame and the linkage member; and a second recovery spring clamped between the linkage member and the pull member

AI summary
A trigger linkage mechanism for use in toy gun includes: a trigger pivoted to a gun frame and formed with a push block; a linkage member having one end formed with a first pivotal part and the other end formed with a second pivotal part. The linkage member is formed with an abutting part disposed between the two pivotal parts and abutted against the push block; a pull member pivoted to the second pivotal part and formed with a pawl part capable of being correspondingly buckled with the buckle part; a first recovery spring clamped between the gun frame and the linkage member; and a second recovery spring clamped between the linkage member and the pull member. Accordingly, the rotation radian and speed of the pawl part is able to be controlled and adjusted.
