In related technologies, the drone parachute is fixedly connected to the drone body via a parachute box, with openings on the box for the parachute lines to pass through and connect to the drone. This allows the parachute to be secured to the drone via the parachute lines. However, this also makes the parachute lines susceptible to damage from external environmental factors during drone flight, reducing their lifespan and increasing the risk of parachute failure and drone damage. Utility Model Content

[0003] The purpose of this disclosure is to provide a drone parachute that can prevent damage from exposed parachute lines and avoid affecting the flight of the drone.

[0004] To achieve the above objectives, a first aspect of this disclosure provides a drone parachute, comprising:

[0005] An umbrella box, wherein the umbrella box is provided with a receiving cavity;

[0006] The umbrella body and paracords are located in the receiving cavity, and the first end of the paracords is connected to the umbrella body;

[0036] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0037] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "higher," "lower," "top," and "bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inner" and "outer" refer to the inner and outer contours of the corresponding component. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0038] This disclosure relates to a drone parachute capable of housing the parachute lines 3 within a parachute case 1, preventing the parachute lines 3 from interfering with the drone's flight. See also Figure 1 and Figure 2 The drone parachute disclosed herein includes a parachute box 1, which serves as the main body of the drone parachute and is provided with a receiving cavity 11. The receiving cavity 11 is used to receive the parachute body 2 and the parachute rope 3. The first end of the parachute rope 3 is connected to the parachute body 2. A parachute rope connector 4 is also provided in the receiving cavity 11. The parachute rope connector 4 is fixedly connected to the parachute box 1, either to the inner wall of the parachute box 1 or to the side wall of the parachute box 1. The second end of the parachute rope 3 is fixedly connected to the parachute rope connector 4, so that the parachute rope 3 can fix the parachute body 2 to the parachute box 1 through the parachute rope connector 4, thereby allowing the parachute body 2 and the parachute rope 3 to be completely located in the parachute box 1.

[0039] The drone parachute disclosed herein provides a mounting base for the second end of the parachute rope 3 by setting a parachute rope connector 4 in the parachute box 1, so that the parachute rope 3 is completely located in the parachute box 1. Compared with the related technology, which requires drilling holes in the parachute box 1 and then fixing the second end of the parachute rope 3 to the fuselage through the holes, this method can prevent the exposed parachute rope 3 from being easily damaged by the external environment, affecting the service life of the parachute rope 3 and the safety of the drone. It can also prevent the exposed parachute rope 3 from interfering with the normal flight of the drone.

[0040] In one embodiment of this disclosure, see Figure 2 , Figure 3 and Figure 4 The paracord connector 4 includes a connecting part 41 and a fixing part 42. The fixing part 42 can cooperate with the umbrella box 1, for example, with the bottom wall or side wall of the umbrella box 1, to connect with the umbrella box 1 and complete the fixation between the paracord connector 4 and the umbrella box 1 support. The connecting part 41 is located on the fixing part 42 and can be located on the top or side of the fixing part 42. It can be ring-shaped and can cooperate with the second end of the paracord 3. For example, the connecting part 41 is ring-shaped. When connecting, it is only necessary to tie the second end of the paracord 3 directly to the ring to complete the connection of the connecting part 41 of the paracord 3. Of course, in other embodiments, the paracord connector 4 can also have other structures, which can be determined according to the actual situation. This disclosure does not limit it.

[0041] In one embodiment of this disclosure, see Figure 2 , Figure 3 and Figure 4 The paracord connector 4 can be T-shaped. The connecting part 41 is fixedly connected to the center of one side of the fixing part 42 and protrudes from the fixing part 42 to facilitate connection with the paracord 3. The fixing part 42 can be sheet-shaped, which allows the fixing part 42 to fit against the inner wall of the umbrella box 1. The fixing part 42 is provided with a first connecting hole 421 and a second connecting hole 422. The first connecting hole 421 is located at the center of the other side of the fixing part 42. The umbrella box 1 can be provided with a connecting hole that mates with the first connecting hole 421 so that the first connecting hole 421 can mate with the first fastener 423 to fix the fixing part 42 to the umbrella box 1.

[0042] In some embodiments, the first fastener 423 can also be used for a fixed connection between the parachute box 1, the parachute cord connector 4, and the drone fuselage. The connection can be achieved by first connecting the parachute cord connector 4 to the parachute box 1 via the first connecting hole 421 and the first fastener 423, and then indirectly connecting the parachute cord connector 4 to the fuselage via the connection between the parachute box 1 and the drone fuselage. This improves the stability of the parachute cord connector 4 and avoids the problem of the parachute cord connector 4 only being connected to the parachute box 1, leading to the parachute cord 3 detaching and the parachute failing if the connection point is damaged. Of course, in other embodiments, the parachute cord connector 4 can also be directly connected to the fuselage via the first fastener 423, depending on the actual situation. This disclosure does not impose any limitations on this.

[0043] Two second connecting holes 422 are provided, symmetrically distributed on both sides of the first connecting hole 421. Connecting holes that mate with the second connecting holes 422 can be provided on the umbrella box 1, allowing the second connecting holes 422 to engage with the second fastener 424 to securely connect the fixing part 42 to the umbrella box 1. By providing the second connecting holes 422 to fix the fixing part 42 to the umbrella box 1, the first connecting hole 421 and the second connecting hole 422 can be engaged, further enhancing the stability of the connection between the paracord connector 4 and the umbrella box 1, and avoiding safety issues caused by the paracord connector 4 detaching.

[0044] In some embodiments, the first connecting hole 421 and the second connecting hole 422 can be threaded holes, and the first fastener 423 and the second fastener 424 can be bolts. When connecting the paracord connector 4 to the umbrella box 1, it is only necessary to align the first connecting hole 421 and the second connecting hole 422 with the corresponding connecting holes on the umbrella box 1, then pass the ends of the bolts through each connecting hole in sequence, and finally fix the bolts with nuts to complete the fixed connection between the paracord connector 4 and the umbrella box 1. Of course, in other embodiments, the connecting part 41 and the fixing part 42 can also be of other structures, depending on the actual situation, and this disclosure does not limit them.

[0045] In one embodiment of this disclosure, see Figure 2 and Figure 5The drone parachute disclosed herein also includes a filling airbag 7, which is located in the receiving cavity 11 and fixedly connected to the parachute box 1. The parachute body 2 is configured to enclose at least part of the filling airbag 7, or the filling airbag 7 can be completely enclosed. When the drone malfunctions, the filling airbag 7 will be activated. The drone malfunction can be determined by monitoring the drone's flight data through different types of sensors on the drone, or by checking whether the drone's circuit is powered on. After the filling airbag 7 is activated, it will expand and support the parachute body 2 and the box cover 6, causing the parachute body 2 and the box cover 6 to detach from the parachute box 1. After the parachute body 2 detaches from the parachute box 1, it will open, allowing the malfunctioning drone to slowly descend from high altitude under the action of the opened parachute body 2, avoiding the safety risks and damage to the drone caused by direct fall after malfunction.

[0046] In one embodiment of this disclosure, see Figure 2 and Figure 5 Multiple parachute rope connectors 4 can be provided, symmetrically distributed around the inflatable bladder 7. Since the parachute body 2 includes the inflatable bladder 7, and the multiple parachute ropes 3 need to be connected symmetrically along the circumference of the parachute body 2 when connecting to it, to avoid the parachute body 2 shifting after opening, the parachute rope connectors 4 need to be arranged symmetrically relative to the inflatable bladder 7 so that after the first end of the parachute rope 3 is connected to the parachute body 2, it can be directly fixed to the corresponding parachute rope connector 4, avoiding entanglement between multiple parachute ropes 3, which would affect the opening and use of the parachute.

[0047] In one embodiment of this disclosure, see Figure 2 and Figure 5 The airbag 7 includes an airbag body 71 and an inflation device 72. The airbag body 71 is located in the receiving cavity 11 and is fixedly connected to the parachute box 1 so that the inflation device 72 can inflate the airbag body 71. The inflation device 72 is located in the airbag body 71 and can inflate the airbag body 71. For example, it can be activated when the drone malfunctions so that the airbag body 71 expands and drives the parachute 2 and the box cover 6 to detach from the parachute box 1. The parachute 2 ensures that the drone can land safely.

[0048] The inflation device 72 is equipped with a pressure boosting valve 721. Since the airbag body 71 is mostly made of multiple fabric pieces sewn together, gaps are inevitable at the seams. If the inflation pressure of the inflation device 72 is too low, the gas entering the airbag body 71 will leak out through the gaps, resulting in a slow inflation speed of the airbag body 71. The parachute body 2 and the cover 6 will also detach from the parachute box 1 at a slower speed, ultimately leading to a longer parachute opening time and increased risk of damage to the drone. However, by pressurizing the gas through the pressure boosting valve 721, the airbag body 71 can be rapidly inflated, causing the parachute body 2 and the cover 6 to detach from the parachute box 1, allowing the parachute to open quickly and ensuring a safe landing for the drone. In some embodiments, the pressure boosting valve 721 can be made of aluminum sheet. Of course, in other embodiments, the structure of the pressure boosting valve 721 and the filling airbag 7 can also be of other types, depending on the actual situation. This disclosure does not impose any limitations on this.

[0049] In one embodiment of this disclosure, see Figure 1 and Figure 2 The drone parachute disclosed herein also includes a connecting frame 5, which can be made of metal to provide good strength and durability. The connecting frame 5 is used to fix the parachute box 1 to the fuselage of the drone, including a first connecting surface 51 for connecting to the fuselage and a second connecting surface 52 for connecting to the parachute box 1. The connection between the first connecting surface 51 and the second connecting surface 52 and the fuselage and the parachute box 1 can be welding, bonding, or bolting, or other connection methods known to those skilled in the art, which will not be elaborated further here. The second connecting surface 52 is also recessed relative to the first connecting surface 51. This arrangement reduces the distance between the top surface of the parachute box 1 and the fuselage after the connecting frame 5 fixes the parachute box 1 to the fuselage, thereby reducing the height of the parachute box 1 protruding from the fuselage, making the overall structure of the drone more compact, and also reducing the flight drag of the drone to a certain extent, thus improving flight efficiency.

[0050] In one embodiment of this disclosure, see Figure 1 and Figure 2The umbrella box 1 is provided with a third connecting hole 53, which penetrates the umbrella box 1 and the second connecting surface 52. The umbrella box 1 and the second connecting surface 52 can be fixedly connected through the third connecting hole 53. The connection method can be by bolts or other connection methods known to those skilled in the art. As described in the above embodiments, a first connection hole 421 can be provided on the parachute cord connector 4. The first connection hole 421 can be concentrically arranged with the third connection hole 53. After the parachute box 1 and the parachute cord connector 4 are fixedly connected by the first fastener 423, the first connection hole 421 and the third connection hole 53, the first fastener 423 can also fix the parachute box 1 and the second connection surface 52 through the third connection hole 53 on the parachute box 1 and the second connection surface 52, thus completing the fixed connection between the parachute box 1 and the fuselage through the connecting bracket 5. In this way, the parachute cord connector 4 can be indirectly connected to the fuselage through the first fastener 423, thereby improving the stability of the parachute cord connector 4 and avoiding the problem that the parachute cord connector 4 is only connected to the parachute box 1. When the connection with the parachute box 1 is damaged, the parachute cord 3 will detach and the parachute will fail.

[0051] In some embodiments, the first connecting hole 421 and the third connecting hole 53 can be threaded holes, and the first connector 423 can be a bolt. When connecting the umbrella box 1 and the paracord connector 4, and the umbrella box 1 and the connecting frame 5, the threaded holes on the three can be aligned, and then the fixing end of the bolt can be passed through the three threaded holes in sequence. Finally, it can be fixed by the nut to complete the fixed connection between the umbrella box 1, the paracord connector 4 and the connecting frame 5.

[0052] In one embodiment of this disclosure, see Figure 5 and Figure 6 The drone parachute disclosed herein also includes a cover 6, which covers the parachute box 1 and seals the parachute body 2 and parachute ropes 3 inside the parachute box 1, preventing rainwater, dust, and other impurities from entering the parachute box 1. A first connecting component 61 is also provided on the side of the cover 6 near the receiving cavity 11. The first connecting component 61 connects the cover 6 to the parachute body 2, making the cover 6 and the parachute body 2 a single unit. This prevents the cover 6 from flying out after the parachute opens, thus avoiding safety risks, and also facilitates subsequent cost recovery of the cover 6 after the parachute opens. In some embodiments, the first connecting component 61 may include a ring and bolts and nuts for fixing the ring to the cover 6. The parachute body 2 and the cover 6 can then be fixedly connected by ropes through the ring. Of course, in other embodiments, the first connecting component 61 may have other structures, depending on the actual situation, and this disclosure does not limit this.

[0053] In one embodiment of this disclosure, see Figure 5 and Figure 6A second connecting component 62 is also provided on the side of the lid 6 away from the receiving cavity 11. This second connecting component 62 can fix the lid 6 to the drone's canopy, making the drone canopy, lid 6, and parachute 2 a single unit. This prevents the lid 6 and drone canopy from flying out after the parachute opens, thus avoiding safety risks. It also facilitates subsequent recovery of the lid 6 and drone canopy after the parachute opens, saving costs. In some embodiments, the second connecting component 62 may include a fastener and bolts and nuts for fixing the fastener to the lid 6. The drone canopy and lid 6 can then be fixedly connected using bolts or adhesive. Of course, in other embodiments, the second connecting component 62 may have other structures, depending on the actual situation, and this disclosure does not limit this.

[0054] In one embodiment of this disclosure, see Figure 2 and Figure 5 A connecting film 63 is provided at the contact point between the umbrella box 1 and the lid 6, which can seal the umbrella box 1 and the lid 6 together. In some embodiments, the connecting film 63 can be double-sided adhesive. Double-sided adhesive has a moderate bonding strength, which can ensure the sealing effect and the connection effect while avoiding the problem that the connection between the umbrella box 1 and the lid 6 is too tight, making it difficult to open the lid 6.

[0055] The drone parachute disclosed herein has a parachute rope connector 4 installed in the parachute box 1, allowing the first end of the parachute rope 3 to be connected to the parachute body 2, and the second end to be fixedly connected to the parachute rope connector 4. This eliminates the need to drill holes in the parachute box 1 to fix the second end of the parachute rope 3 to the fuselage, avoiding damage to the exposed parachute rope 3 and affecting the drone's flight. When connecting the parachute box 1 to the fuselage, the connecting frame 5 can also be used to lower the height of the top of the parachute box 1 from the fuselage, improving the overall compactness of the drone. In the event of a drone malfunction, the inflatable airbag 7 will activate, inflating the parachute body 2 and the box cover 6, causing the parachute body 2 and the box cover 6 to detach from the parachute box 1. After detaching from the parachute box 1, the parachute body 2 will open, allowing the malfunctioning drone to slowly descend from a high altitude under the action of the opened parachute body 2, avoiding the safety risks and damage to the drone caused by a direct fall after a malfunction.

[0056] A second aspect of this disclosure also provides a drone, see [link to relevant documentation]. Figure 7 and Figure 8The system includes a fuselage 8 and the drone parachute described in the above embodiments, with the drone parachute fixedly connected to the fuselage 8. Specifically, the fuselage 8 may include a crossbeam 81, which is the main body of the transverse connecting part of the fuselage 8. The drone parachute may include a parachute box 1 and a connecting frame 5. The connecting frame 5 may have an approximately Z-shaped structure. The first connecting surface 51 on the connecting frame 5 can overlap the crossbeam 81 and is fixedly connected to the crossbeam 81. The fixed connection can be achieved by welding or bolting. The second connecting surface 52 can support the parachute box 1 and contact the bottom surface of the parachute box 1, and is fixedly connected to the parachute box 1. The fixed connection can also be achieved by welding or bolting.

[0057] In some embodiments, an extension plate 511 extending vertically may be provided on the first connecting surface 51. The extension plate 511 is attached to and fixedly connected to the side plate 82 on the fuselage 8. The fixed connection may be achieved by welding or bolting, etc., to further increase the stability of the connection between the connecting frame 5 and the fuselage 8. A support frame 54 may also be provided at the bottom of the second connecting surface 52. The support frame 54 may be a tripod structure to enable the connecting frame 5 to have a better ability to support the parachute box 1. Of course, in other embodiments, the connection method between the fuselage 8 and the parachute may also be other, depending on the actual situation. This disclosure does not limit this.

[0058] By using the drone parachute disclosed herein, damage to the parachute lines 3 due to exposure and the resulting impact on drone flight can be avoided. The connection and cooperation relationships of other components in the parachute can be found in the descriptions of the above embodiments, and will not be repeated here.

[0059] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0061] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
