Description

Technical Field

[0001] This utility model belongs to the technical field of aircraft parachute landing systems, specifically relating to a modular parachute deployment mechanism suitable for multiple loads. Background Technology

[0002] In some scenarios, such as during landing, aircraft need to use parachutes to slow down their flight speed. Currently, aircraft typically have a parachute compartment within the fuselage to hold the parachutes, which include a pilot parachute and a main parachute. When the aircraft lands, the compartment door opens, and gravity deploys the main parachute and pilot parachute outside the compartment, thus slowing the aircraft down.

[0003] A prior art patent, CN215043748U, describes a parachute altitude control and deployment mechanism. This patent includes a drone and a deployment box. The drone has a connecting base at its top center, and the bottom of the deployment box is connected to the top of the connecting base. The deployment box includes a shell and a top cover. A parachute is housed inside the shell, and a rope is connected to the bottom of the parachute. A magnet is installed inside one end of the top cover, and a rotating shaft is located at the end of the top cover opposite the magnet. A connecting post is located below the rotating shaft, and a first spring is sleeved on the outside of the connecting post. The mechanism utilizes the top cover's... A magnetic block is installed at one end, and a first spring is installed on the outside of the rotating shaft at the other end. After the magnetic block and electromagnet are de-energized, the first spring, which was originally stretched, quickly contracts, causing the top cover to rotate quickly around the rotating shaft, shortening the opening time of the top cover, and also increasing the gap when the top cover is opened, which is more conducive to the deployment of the parachute. However, in actual use, there are still the following shortcomings: In practice, when this patent is used in conjunction with the hatch to open the parachute, the parachute cannot be opened in a timely manner according to the opening operation of the hatch, which makes it difficult for the parachute to be fully deployed, thereby reducing the ease of use of the device.

[0004] Therefore, a modular parachute deployment mechanism suitable for multiple loads is needed to solve the problem in the prior art that the parachute cannot be deployed in a timely manner according to the opening operation of the hatch. Utility Model Content

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5This utility model provides a modular parachute deployment mechanism suitable for multiple loads, including a fixed base 1, a mounting plate 2, a parachute compartment 3, and a hatch 4. The mounting plate 2 is located on the upper part of the fixed base 1, the parachute compartment 3 is fixedly connected to the top of the mounting plate 2, and the hatch 4 is located on the upper part of the parachute compartment 3. The upper part of the fixed base 1 has a mounting cavity 101, and the mounting plate 2 is slidably disposed within the fixed base 1 through the mounting cavity 101. A limit block 201 is fixedly connected to the inner side wall of the mounting cavity 101, and a limit groove 203 is formed on the mounting plate 2 at the corresponding position of the limit block 201. A second spring 202 is fixedly connected to the bottom of the mounting plate 2. A parachute 5 is disposed at the top of the parachute compartment 3, and a spring 202 is connected to the bottom of the parachute 5. Rope 6, with a movable plate 8 fixedly connected to its bottom end. The movable plate 8 has four positioning holes 801 evenly distributed. A first spring 9 is fixedly connected to the bottom of the movable plate 8 and is located inside the parachute compartment 3 via the movable plate 8. A parachute opening mechanism 7 is located inside the parachute compartment 3 via the positioning holes 801 on the movable plate 8. The parachute opening mechanism 7 is used to control the opening operation of the parachute 5. The door 4 is located on the upper part of the parachute compartment 3 and is opened and closed by the control system. Multiple limit blocks 201 are evenly distributed inside the fixed base 1. The mounting plate 2 is limited and slids within the fixed base 1 by the limit blocks 201 and the limit grooves 203.

[0025] The mounting plate 2 integrates a CAN bus communication socket at its bottom to transmit the status signal of the hatch 4 to the flight controller.

[0026] Further as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that the umbrella opening mechanism 7 includes a positioning cylinder 701, which is fixedly connected to the top of the mounting plate 2 and located inside the umbrella compartment 3. A through-hole 702 is provided on the positioning cylinder 701, corresponding to the positioning port 801. An installation groove 703 is provided above the through-hole 702 inside the positioning cylinder 701. A third spring 704 is fixedly installed in the installation groove 703. A sliding plate 705 is fixedly connected to the bottom of the third spring 704 and slides within the installation groove 703. A matching block 706 is fixedly connected to the bottom of the sliding plate 705. A positioning block 708 is provided on the outer side of the matching block 706, and a fixed shaft 7 is rotatably connected to the positioning block 708. 09. The positioning block 708 is rotatably set inside the through opening 702 via the fixed shaft 709. The positioning block 708 has a through groove 7010, which is set at an angle and the higher end is set away from the fixed shaft 709. The positioning rod 707 is slidably set inside the through groove 7010. The positioning rod 707 is fixedly connected to the matching block 706. The matching block 706 has a top rod 7012 below it. The bottom end of the top rod 7012 is fixedly connected to an electric telescopic rod 7011. The electric telescopic rod 7011 is fixedly connected to the fixed base 1. The bottom end of the positioning cylinder 701 is connected to the upper part of the mounting plate 2. The electric telescopic rod 7011 passes through the mounting plate 2 on the fixed base 1 and slides inside the positioning cylinder 701.

[0027] Specifically, the inclination angle of the through groove 7010 is set to 45°±2° to ensure that the positioning block 708 rotates when the positioning rod 707 slides.

[0028] The electric telescopic boom 7011 requires both the hatch 4 opening signal and the altitude sensor (not shown in the attached diagram) to activate.

[0029] This solution has the following working process: When this device is in use, the entire device is fixedly installed via the fixing base 1 for use. During its use, the opening and closing of the hatch 4 facilitates the deployment of the parachute 5 inside the parachute compartment 3. At this time, the electric telescopic rod 7011 operates, thereby pushing the top rod 7012 upward. During the upward movement of the top rod 7012, it pushes the matching block 706, causing the matching block 706 to slide within the mounting groove 703 via the sliding plate 705. Furthermore, the sliding of the matching block 706 causes the positioning rod 707 to slide within the through groove 7010. The positioning rod 707 slides within the through slot 7010, causing the positioning block 708 to rotate within the through opening 702 via the fixed shaft 709. This releases the positioning block 708 from its limit at the positioning opening 801. At this point, the elastic action of the first spring 9 pushes the movable plate 8 to slide on the positioning cylinder 701, thereby pushing the parachute 5 and ropes 6 out of the parachute compartment 3, thus completing the deployment of the parachute 5. Through the above process, accidental deployment of the parachute 5 can be prevented, improving the deployment efficiency of the parachute 5. Furthermore, its signal connection facilitates adaptation to multiple scenarios and enhances its modularity.

[0030] In summary, the parachute deployment mechanism 7 can autonomously control the deployment of the parachute 5 located inside the parachute compartment 3 based on the opening operation of the hatch 4, thereby improving the timeliness of the parachute 5 deployment. This allows for increased efficiency in parachute deployment based on the aircraft's status and enhances the modular applicability of the device.
