DETAILED DESCRIPTION

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0020] See Figure 1-Figure 4 , the utility model provides a technical solution:

[0021] The automatic synchronization linkage mechanism for an electric gun includes an electric gun assembly, a sliding assembly, a support plate 1, a rotating plate 2, a motor 3, and linear guides 4. A sleeve 5 is mounted on the support plate 1, on which the rotating plate 2 is mounted. A motor 3 is mounted at the bottom of the support plate 1 and connected to the sleeve 5. Linear guides 4 are mounted at the four corners of the support plate 1, and fixed plates 6 are mounted on the linear guides 4. The electric gun assembly is mounted on one end of the fixed plate 6, and a connecting rod 7 is mounted on the other end of the fixed plate 6, which is connected to the rotating plate 2. Sliding assemblies are mounted at each end of the support plate 1. The support plate 1 serves as the supporting structure for the entire mechanism, playing the important role of supporting and securing the other components. The rotating plate 2 is connected to the electric gun assembly via a hinge or other connection method, allowing relative rotation between them. The design of the rotating plate 2 generally requires consideration of factors such as its rotation range, rotation accuracy, and coordination with other components to ensure that the mechanism can move according to the predetermined trajectory and pattern. A bearing and a sliding core are mounted within the sleeve 5, and the sliding core is mounted within the bearing. Motor 3 is the primary power source for the automatic synchronization linkage mechanism of the electric gun. It generates rotational motion to drive components such as the sliding core and rotating plate 2, thereby achieving automatic synchronization and coordinated movement of the entire mechanism. Linear guides 4 guide and support the movement of the fixed plate 6 in the automatic synchronization linkage mechanism of the electric gun. They ensure that the fixed plate 6 can move linearly along a predetermined trajectory during movement, thereby improving the movement accuracy and stability of the mechanism. Connecting rod 7 is one of the key components connecting the rotating plate 2 and the fixed plate 6. It is connected to the rotating plate 2 and the fixed plate 6 via a hinge or other connection method, allowing relative movement between them. The design of connecting rod 7 generally requires consideration of factors such as its length, angle, and coordination with other components to ensure that the mechanism can move according to the predetermined trajectory and method. The electric gun assembly, as the core executive component of the mechanism, is primarily responsible for generating and transmitting the required electricity or energy to complete specific operating tasks. The sliding assembly plays a key connecting and transmission role in the automatic synchronization linkage mechanism of the electric gun.

[0022] In some embodiments, the stun gun assembly includes a connector 8, a flange bearing 9, and a stun gun 10. The connector 8 is mounted on the fixed plate 6, the flange bearing 9 is mounted on the connector 8, and the stun gun 10 is mounted on the connector 8, with one end of the stun gun 10 rotatably connected to the flange bearing 9. The connector 8 ensures that the stun gun 10 is stably mounted on the fixed plate 6 and can withstand the various forces generated by the stun gun 10 during operation, ensuring precise alignment and a tight connection between the stun gun 10 and the fixed plate 6. This precision is crucial to ensuring the performance and accuracy of the stun gun 10. Within the stun gun 10 assembly, the flange bearing 9 primarily serves as support and rotational support. It allows the stun gun 10 to rotate within a certain range on the fixed plate 6 to accommodate different shooting angles and positions. Furthermore, the flange bearing 9 provides precise rotational control, ensuring the stability of the stun gun 10 during rotation.

[0023] In some embodiments, the sliding assembly includes a frame 11, an auxiliary plate 12, a first cylinder 13, a slide 14, a slider 15, and a first limit plate 16. The auxiliary plate 12 is provided on the frame 11. The first cylinder 13 is provided on one end of the auxiliary plate 12. The piston portion of the first cylinder 13 is connected to the support plate 1. The slide 14 is provided on the other end of the auxiliary plate 12. The first limit plate 16 is provided on the support plate 1. A slider 15 is provided between the slider 14 and the first limit plate 16, and the slider 15 is fixedly connected to the first limit plate 16. Among them, the frame 11 provides a stable mounting platform for other components, ensuring the overall stability and reliability of the sliding assembly. The auxiliary plate 12 serves as a bridge connecting the frame 11 and the first cylinder 13 and the slide 14, playing the role of transmitting force and motion, and ensuring that the first cylinder 13 can smoothly push the support plate 1. The first cylinder 13 pushes and pulls the support plate 1 through the telescopic movement of its piston portion, thereby driving the sliding of the entire sliding assembly. This power transmission mode is efficient, stable and easy to control. The slide plate 14, the slider 15 and the first limit plate 16 play a role in assisting the first cylinder 13 and the entire device to move up and down, reducing friction and wear and improving the movement accuracy and stability of the mechanism.

[0024] In some embodiments, a second stopper 17 is provided on the support plate 1, located near one end of the rotating plate 2. This second stopper 17 prevents the rotating plate 2 from moving beyond a predetermined range, thereby preventing potential damage or misoperation. This second stopper 17 acts as a "stopper," ensuring that the rotating plate 2 moves within a safe operating area.

[0025] In some embodiments, a second air cylinder 18 is disposed beneath the connector 8. The addition of the second air cylinder 18 provides additional driving force for the connector 8 and its connected components. The second air cylinder 18 also provides necessary support for the connector 8 and its connected components. This support helps maintain the stability and reliability of the mechanical system. By adjusting the extension and retraction of the second air cylinder 18, the position and posture of the connector 8 and its connected components can be fine-tuned. This adjustment allows the mechanical system to better adapt to different working environments and task requirements.
