Description

Technical Field

[0001] This utility model relates to the field of flying car technology, and in particular to a flying car parachute system. Background Technology

[0002] Flying cars are future transportation vehicles that combine the functions of automobiles and airplanes, capable of both ground driving and flight. Their core features include: employing electric vertical takeoff and landing (eVTOL) technology, allowing them to take off without a runway; and being equipped with multi-rotor or tiltrotor systems to switch between vertical takeoff and landing and cruise modes. They have broad application prospects, such as alleviating urban air traffic congestion, rapid emergency response, and transporting supplies to remote areas.

[0003] In the prior art, for example, Chinese Patent No. CN222452539U discloses a flying car parachute system, including a flying car, a parachute, a heat shield, a parachute opening agent, and a parachute opening device. The flying car has a parachute compartment on its top, the heat shield is slidably disposed within the parachute compartment, the parachute opening agent is located between the heat shield and the parachute compartment, the parachute is located in the parachute compartment and above the heat shield, and the bottom of the parachute is rotatably connected to the flying car. The parachute opening device is installed inside the flying car, extends into the parachute opening agent, and is controlled by a controller on the flying car. The parachute system has a simple structural design and allows the flying car's parachute to deploy quickly in the event of a malfunction.

[0004] While the above-mentioned scheme has the advantages mentioned above, its disadvantages are as follows: Although it can trigger a signal from the flying car's controller to the parachute deployment device to ignite the parachute detonator in the event of a malfunction, producing a large amount of high-temperature gas, the gas expands and moves towards the bottom of the heat shield, causing the heat shield to slide outward inside the flying car's parachute compartment, simultaneously opening the parachute and the parachute compartment canopy, the method of igniting the parachute detonator to open the parachute is problematic. During the use of the flying car, the driver may accidentally activate the parachute deployment device switch, accidentally releasing the parachute. This could lead to damage to the flying car, heat shield, and canopy due to the explosion of the detonator, thereby increasing the maintenance costs of the flying car. Utility Model Content

[0005] The purpose of this invention is to address the problem in existing technologies where, although a malfunction in the flying car triggers a signal from the flying car's controller to ignite the parachute detonator, producing a large amount of high-temperature gas that expands and moves towards the bottom of the heat shield, causing the heat shield to slide outwards within the flying car's parachute compartment and simultaneously opening the parachute and the parachute compartment canopy, the method of igniting the detonator to open the parachute is problematic. During use, the driver may accidentally activate the detonator switch, unintentionally releasing the parachute and potentially damaging the flying car, heat shield, and canopy due to the detonator explosion, thus increasing maintenance costs.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a flying car parachute system, comprising: a flying car body, and further comprising:

[0007] An ejection bay is located on the top of the flying vehicle. An ejection bay cover is installed inside the ejection bay, and a sealing cover plate is slidably connected inside the ejection bay. A parachute body is installed inside the ejection bay, and the connecting rope of the parachute body is fixedly connected to the inner wall of the ejection bay. Two airbag bays are symmetrically located on the top of the flying vehicle. High-pressure airbags are installed inside the airbag bays. A connecting pipe is fixedly connected to the outer surface of the high-pressure airbags. One end of the connecting pipe extends into the interior of the ejection bay. A solenoid valve is fixedly connected to the connecting pipe near the inner wall of the high-pressure airbag.

[0008] Preferably, the bottom of the high-pressure airbag is fixedly connected to the bottom of the inner wall of the airbag chamber, the interior of the high-pressure airbag is connected to the other end of the connecting pipe, and the top of the inner wall of the airbag chamber is detachably installed with an airbag cover by bolts.

[0009] Preferably, the inner wall of the ejection compartment has two symmetrical connecting holes, and the ejection compartment, the two connecting holes, and the two airbag compartments are connected to each other.

[0010] Preferably, one end of the connecting pipe is connected to the interior of the ejection chamber slot, and the outer surface of the connecting pipe is fixedly connected to the interior of the connecting hole.

[0011] Preferably, the outer surface of the sealing cover is provided with an annular groove, and a sealing ring is fixedly connected to the inner wall of the annular groove. The sealing ring is made of rubber.

[0012] Preferably, a pull rope is fixedly connected to the bottom of the sealing cover, and one end of the pull rope is fixedly connected to the bottom of the inner wall of the ejection compartment.

[0013] Preferably, the top of the flying car body is provided with a second groove, which is connected to the ejection compartment slot. A round rod is fixedly connected to the opposite side of the inner wall of the groove, and a connecting block is rotatably connected to the outer surface of the round rod. The connecting block is fixedly connected to the ejection compartment cover.

[0014] Preferably, the bottom of the connecting block is provided with a groove, and two torsion springs are symmetrically arranged on the outer surface of the round rod, and the torsion springs are fixedly connected to the connecting block and the round rod respectively.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model controls the opening of the solenoid valve via a controller, allowing high-pressure gas from inside the high-pressure airbag to enter the ejection chamber through the connecting pipe. With the cooperation of the sealing cover and sealing ring, the high-pressure gas cannot escape through the gap between the sealing cover and the ejection chamber. When the air pressure between the ejection chamber and the sealing cover increases rapidly, the sealing cover is subjected to a large force, causing it to be ejected along the inside of the ejection chamber, simultaneously ejecting the parachute body. This allows the parachute body to open quickly, providing a landing buffer for the flying car. This eliminates the need for an explosive parachute to open the parachute, thus avoiding damage to the flying car body, sealing cover, and ejection chamber cover due to accidental contact, thereby reducing the maintenance cost of the flying car body.

[0017] 2. In this invention, when the parachute body is rapidly ejected, a force is applied to the ejection canopy, causing the ejection canopy and connecting block to rotate upwards around the outer surface of the round rod. Simultaneously, the torsion spring is twisted. Under the restoring force of the torsion spring, the connecting block and ejection canopy can be buffered to a certain extent, preventing the ejection canopy from directly detaching from the flying car body or from being damaged due to a collision. Simultaneously, through the setting of the pull rope, when the sealing cover slides out of the ejection canopy due to high-pressure gas, the sealing cover can be pulled back by the pull rope, avoiding the difficulty of finding the sealing cover after it detaches from the flying car body. This can prevent the sealing cover and ejection canopy from directly detaching from the flying car body, thus facilitating the reuse of the sealing cover and ejection canopy.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Examples, such as Figure 1-5 As shown, this utility model provides a flying car parachute system, including: a flying car body 1, and an ejection bay 9, which is opened on the top of the flying car. An ejection bay cover 2 is provided inside the ejection bay 9, and a sealing cover plate 16 is slidably connected inside the ejection bay 9. A parachute body 4 is provided inside the ejection bay 9, and the connecting rope of the parachute body 4 is fixedly connected to the inner wall of the ejection bay 9. Two airbag bays 12 are symmetrically opened on the top of the flying car body 1. A high-pressure airbag 11 is provided inside the airbag bay 12. A connecting pipe 14 is fixedly connected to the outer surface of the high-pressure airbag 11. One end of the connecting pipe 14 extends into the interior of the ejection bay 9. A solenoid valve 19 is fixedly connected to the connecting pipe 14 near the inner wall of the high-pressure airbag 11.

[0028] Furthermore, such as Figure 1-5As shown, the bottom of the high-pressure airbag 11 is fixedly connected to the bottom of the inner wall of the airbag chamber 12. The interior of the high-pressure airbag 11 is connected to the other end of the connecting pipe 14. The top of the inner wall of the airbag chamber 12 is detachably installed with an airbag cover 3 by bolts. The high-pressure airbag 11 facilitates the delivery of high-pressure gas to the connecting pipe 14, and the airbag cover 3 facilitates the protection of the high-pressure airbag 11.

[0029] Furthermore, such as Figure 1-5 As shown, two connecting holes 13 are symmetrically opened on the inner wall of the ejection compartment 9. The ejection compartment 9, the two connecting holes 13 and the two airbag compartments 12 are connected. The connection holes 13 facilitate the connection between the ejection compartment 9 and the two airbag compartments 12.

[0030] Furthermore, such as Figure 1-5 As shown, one end of the connecting pipe 14 is connected to the inside of the ejection chamber 9, and the outer surface of the connecting pipe 14 is fixedly connected to the inside of the connecting hole 13. Through the above arrangement, the gas inside the connecting pipe 14 can enter the inside of the ejection chamber 9.

[0031] Furthermore, such as Figure 1-5 As shown, an annular groove 17 is provided on the outer surface of the sealing cover plate 16, and a sealing ring 18 is fixedly connected to the inner wall of the annular groove 17. The sealing ring 18 is made of rubber, and the sealing ring 18 provides a certain sealing effect.

[0032] Furthermore, such as Figure 1-5 As shown, a pull rope 15 is fixedly connected to the bottom of the sealing cover 16. One end of the pull rope 15 is fixedly connected to the bottom of the inner wall of the ejection compartment 9. The sealing cover 16 is pulled by the pull rope 15 to prevent the sealing cover 16 from becoming detached from the flying car body 1 and making it inconvenient to find.

[0033] Furthermore, such as Figure 1-5 As shown, the top of the flying car body 1 has a groove 2 10, which is connected to the ejection compartment slot 9. A round rod 7 is fixedly connected to the opposite side of the inner wall of the groove. A connecting block 5 is rotatably connected to the outer surface of the round rod 7. The connecting block 5 is fixedly connected to the ejection compartment cover 2. With the above arrangement, the connecting block 5 can rotate around the outer surface of the round rod 7, and synchronously drive the ejection compartment cover 2 to rotate.

[0034] Furthermore, such as Figure 1-5 As shown, the bottom of the connecting block 5 is provided with a groove 6, and two torsion springs 8 are symmetrically arranged on the outer surface of the round rod 7. The torsion springs 8 are fixedly connected to the connecting block 5 and the round rod 7 respectively, and play a certain buffering effect under the reset force of the torsion springs 8.

[0035] Working principle: In emergency situations requiring the ejection of the parachute body 4, the pilot can press the ejection switch to open the solenoid valve 19 via the controller. This allows the high-pressure gas inside the high-pressure airbag 11 to enter the ejection chamber through the connecting pipe 14. With the cooperation of the sealing cover 16 and the sealing ring 18, the high-pressure gas cannot escape through the gap between the sealing cover 16 and the ejection chamber 9. When the air pressure between the ejection chamber 9 and the sealing cover 16 increases rapidly, the sealing cover 16 is subjected to a large force, causing it to eject along the inside of the ejection chamber 9, simultaneously ejecting the parachute body 4. This allows the parachute body 4 to open quickly, providing a landing buffer for the flying car body 1. This eliminates the need for an explosive release to open the parachute body 4, thus preventing accidental damage to the flying car body 1, sealing cover 16, and ejection chamber. In the event of damage to the ejection canopy 2, the maintenance cost of the flying car body 1 is reduced. When the parachute body 4 is ejected rapidly, a force is applied to the ejection canopy 2, causing the ejection canopy 2 and the connecting block 5 to rotate upward around the outer surface of the round rod 7. Simultaneously, the torsion spring 8 is twisted. Under the restoring force of the torsion spring 8, the connecting block 5 and the ejection canopy 2 can be buffered to prevent the ejection canopy 2 from directly detaching from the flying car body 1 or from being damaged due to a collision. Simultaneously, through the setting of the pull rope 15, when the sealing cover 16 slides out of the ejection slot 9 due to high-pressure gas, the sealing cover 16 can be pulled back by the pull rope 15, so as to avoid the sealing cover 16 being difficult to find after it is separated from the flying car body 1. This can prevent the sealing cover 16 and the ejection canopy 2 from directly detaching from the flying car body 1, thereby facilitating the reuse of the sealing cover 16 and the ejection canopy 2.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
