The shapes of the existing parachute ejection devices are relatively rough, with low adaptability to the products used, affecting the experience, and the processing method is relatively simple, prone to quality problems. Moreover, for the existing parachute ejection devices, the actual products often have excessive strength and weight.

[0004] Therefore, an automatic ejection parachute device is proposed. Summary of the Utility Model

[0006] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0007] The automatic ejection parachute device includes a parachute cabin box. Inside the parachute cabin box, an ejection base is fixedly installed. At the inner bottom of the parachute cabin box, a large-torque servo is fixedly installed, and a metal servo arm is fixedly installed at the output end of the large-torque servo. At the bottom surface of the ejection base, a tongue limiting seat is fixedly installed. Inside the tongue limiting seat, a tongue plate is movably inserted. The tongue plate and the metal servo arm are hinged and installed. Small-diameter through grooves and large-diameter through grooves are formed on the surface of the tongue plate. At the top surface of the tongue plate, a spring base is fixedly installed, and a locking spring is fixedly installed between the end face of the spring base and the end face of the tongue limiting seat. A spring limiting rod is inserted into the ejection base, the tongue limiting seat, and the tongue plate. A snap ring is clamped on the surface of the spring limiting rod. The top end of the spring limiting rod is fixedly installed with a parachute cabin bottom plate, and a main spring is sleeved on the surface of the spring limiting rod.

[0008] Further, a power control interface is arranged on the surface of the parachute cabin box, and the power control interface is connected to the large-torque servo. The top surface of the parachute cabin box is covered with a parachute cabin cover.

[0009] Further, the parachute cabin box includes a cylinder body. Multiple installation bumps are fixedly installed on the surface of the cylinder body.

[0025] Such as Figures 1 to 5As shown in the figure, the automatic ejection parachute device includes a parachute cabin box 1. Inside the parachute cabin box 1, an ejection base 4 is fixedly installed. At the inner bottom of the parachute cabin box 1, a large-torque servo 5 is fixedly installed, and the output end of the large-torque servo 5 is fixedly installed with a metal servo arm 6. At the bottom surface of the ejection base 4, a tongue limiting seat 7 is fixedly installed. Inside the tongue limiting seat 7, a tongue plate 8 is movably inserted. The tongue plate 8 and the metal servo arm 6 are hinged. On the surface of the tongue plate 8, a small-diameter through groove 81 and a large-diameter through groove 82 are opened. On the top surface of the tongue plate 8, a spring base 9 is fixedly installed, and a locking spring 10 is fixedly installed between the end surface of the spring base 9 and the end surface of the tongue limiting seat 7. A spring limiting rod 11 is inserted into the ejection base 4, the tongue limiting seat 7, and the tongue plate 8. A snap ring 12 is clamped on the surface of the spring limiting rod 11. The top end of the spring limiting rod 11 is fixedly installed with a parachute cabin bottom plate 13, and a main spring 14 is sleeved on the surface of the spring limiting rod 11. More specifically, after the parachute is folded, it is installed on the parachute cabin bottom plate 13. Press the parachute cabin bottom plate 13 to the limit position. At this time, the locking spring 10 pushes the tongue plate 8 to clamp the limiting part of the spring limiting rod 11. When it is necessary to eject the parachute, a trigger command is sent through the power control interface 3. The large-torque servo 5 drives the metal servo arm 6 to pull the tongue plate 8 to move outwards so that it disengages from the limiting part of the spring limiting rod 11. At this time, the main spring 14 releases its elastic force to push the parachute cabin bottom plate 13, realizing the high-speed ejection of the parachute from the parachute cabin box 1. After pushing out a sufficient stroke, the snap ring 12 at the bottom of the spring limiting rod 11 is limited by the tongue limiting seat 7 to keep the parachute connected to the ejection device to realize the process of slow falling of the parachute after throwing.

[0026] On the surface of the parachute cabin box 1, a power control interface 3 is provided, and the power control interface 3 is connected to the large-torque servo 5. The top surface of the parachute cabin box 1 is covered with a parachute cabin cover 2. More specifically, through the power control interface 3, a trigger command can be triggered. Through the power control interface 3, the large-torque servo 5 can be triggered to rotate. By covering the parachute cabin cover 2 on the top surface of the parachute cabin box 1, the parachute cabin cover 2 can be pushed open when the parachute is ejected.

[0027] The parachute cabin box 1 includes a cylinder body 101. On the surface of the cylinder body 101, multiple groups of installation bumps 102 are fixedly installed. On the inner wall of the cylinder body 101, a stepped part 103 is provided. Inside the cylinder body 101 and at the top of the stepped part 103, the ejection base 4 is fixedly installed. More specifically, through the installation bumps 102 on the surface of the cylinder body 101, it is convenient to fix the ejection device. Through the stepped part 103, the ejection base 4 can be fixedly installed.

[0028] The spring limit rod 11 includes a rod body 1101. The rod body 1101 is movably inserted into the ejection base 4, the tongue limit seat 7, and the tongue plate 8. A notch 1102 is formed on the surface of the rod body 1101. An installation disk 1103 is fixedly installed at the top end of the rod body 1101, and a parachute compartment bottom plate 13 is fixedly installed on the top surface of the installation disk 1103. More specifically, when in the limit position, the small-diameter through groove 81 on the surface of the tongue plate 8 and the notch 1102 on the surface of the rod body 1101 are clamped to limit the rod body 1101. When the large-torque servo 5 drives the metal servo arm 6 to pull the tongue plate 8 outward, the large-diameter through groove 82 on the surface of the tongue plate 8 corresponds to the rod body 1101, enabling the vertical movement of the rod body 1101.

[0029] The diameter of the small-diameter through groove 81 on the surface of the tongue plate 8 is equal to the diameter of the notch 1102, and the diameter of the rod body 1101 is equal to the diameter of the large-diameter through groove 82. More specifically, due to the equal diameters of the small-diameter through groove 81 and the notch 1102, the rod body 1101 can be limited, and due to the equal diameters of the rod body 1101 and the large-diameter through groove 82, the relative movement between the rod body 1101 and the tongue plate 8 can be realized.

[0030] Convex strips are provided on the inner wall of the cylinder body 101, and notches are formed on the surface of the parachute compartment bottom plate 13. The notches on the surface of the parachute compartment bottom plate 13 and the convex strips on the inner wall of the cylinder body 101 are correspondingly arranged. More specifically, by meshing the notches on the surface of the parachute compartment bottom plate 13 with the convex strips on the inner wall of the cylinder body 101, the vertical movement of the parachute compartment bottom plate 13 can be limited and guided.

[0031] In summary: After folding the parachute, it is installed on the parachute compartment bottom plate 13. When the parachute compartment bottom plate 13 reaches the limit position, the locking spring 10 pushes the tongue plate 8 to clamp the limit part of the spring limit rod 11. When the parachute needs to be ejected, a trigger command is sent through the power control interface 3. The large-torque servo 5 drives the metal servo arm 6 to pull the tongue plate 8 outward to disengage it from the limit part of the spring limit rod 11. At this time, the main spring 14 releases its elastic force to push the parachute compartment bottom plate 13, realizing the high-speed ejection of the parachute from the parachute compartment box 1. After pushing out a sufficient stroke, the snap ring 12 at the bottom of the spring limit rod 11 is limited by the tongue limit seat 7 to keep the parachute connected to the ejection device and realize the process of slow falling of the parachute.
