Description

Technical Field

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

[0002] Drone parachutes are emergency recovery and passive safety protection devices designed for drone flight malfunctions. They can automatically detect abnormal drone attitudes, sudden acceleration drops, and other uncontrollable states to trigger parachute deployment. Once activated, they can quickly eject and unfold the parachute, using air resistance to slow the drone's descent. This reduces the risk of damage to the drone itself and its expensive onboard equipment, and also prevents it from crashing and causing injury to people and facilities on the ground. They are widely compatible with various mainstream drones, including consumer and industrial drones.

[0003] Current drone parachutes typically consist of a canopy, a push plate, a triggering device, and an ejection mechanism, all housed within a canopy compartment. The triggering device controls the ejection mechanism, which pushes the push plate to eject the canopy from the compartment. However, during the ejection process, uneven force distribution can occur on the push plate, causing it to tilt. Under the ejection mechanism's influence, the push plate moves rapidly towards the hatch, potentially causing a point on it to violently collide with the inner wall of the canopy compartment, resulting in the push plate jamming and hindering canopy opening. Furthermore, after separating from the canopy, the push plate is prone to wobbling, which can also collide with the inner wall of the canopy, damaging the compartment and reducing its lifespan.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes a drone parachute compartment, which aims to solve the problem that drone parachutes are prone to jamming during the opening process.

[0006] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0007] A drone parachute compartment includes a compartment body with an ejection assembly at the bottom. The ejection assembly has a push plate connected to its upper end for ejecting the parachute out of the hatch. The push plate has extensions on at least one opposite side, each extension extending to and abutting against the inner wall of the compartment body. When the push plate is controlled to move, it can reciprocate along the inner wall of the compartment body toward the hatch and the bottom of the compartment.

[0008] Preferably, the extension includes a connecting plate, and the inner wall of the parachute cabin body is provided with a guide groove from the bottom of the cabin towards the hatch at the corresponding position of the connecting plate. One end of the connecting plate is fixedly connected to the push plate, and the other end is embedded in the guide groove and slidably connected to the inner wall of the parachute cabin body.

[0009] Preferably, the guide groove is composed of two parallel first limiting plates, which are fixedly connected to the inner wall of the parachute compartment.

[0010] Preferably, a guide plate is fixedly connected to the end of the connecting plate away from the push plate, and the guide plate is embedded in the guide groove and slidably connected to the inner wall of the umbrella compartment body.

[0011] Preferably, each of the connecting plates has an arc-shaped guide portion at the end away from the push plate, and the arc-shaped guide portion is located at the upper end of the connecting plate.

[0012] Preferably, each of the extensions is provided with at least one reinforcing rib at the connection between it and the push plate.

[0013] Preferably, a support plate is fixedly connected to the bottom of the umbrella compartment body, the push plate is disposed above the support plate, and a surrounding plate is provided around the push plate and the connecting plate at the upper end of the support plate. The end of the surrounding plate away from the push plate is connected to the corresponding first limiting plate to form an integral whole.

[0014] Preferably, the support plate has a mounting groove at its bottom, the ejection assembly includes a spring, the spring is installed in the mounting groove, and the upper end of the spring is connected to the push plate.

[0015] Preferably, the support plate is provided with a second limiting plate around the periphery of the mounting groove, and the push plate has an avoidance groove at its lower end.

[0016] Preferably, the extension portion has four parts, which are fixedly connected to the periphery of the push plate in a cross-shaped symmetrical arrangement.

[0017] The beneficial effects of this utility model are:

[0018] The technical solution of this utility model provides extensions on at least one opposite side of the push plate. These extensions abut against the inner wall of the parachute compartment, thereby limiting the push plate and reducing its swaying during ejection. Simultaneously, the extensions can reciprocate along the inner wall of the parachute compartment towards the hatch and floor, thus pushing the parachute out of the hatch. Because the push plate is limited by the inner wall of the parachute compartment and guided, it moves smoothly during ejection, preventing the inner wall of the parachute compartment from jamming the push plate and affecting parachute opening.

[0025] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] As described in the background art, there is a certain gap between the push plate 2 used to propel the parachute and the inner wall of the parachute compartment in current UAV parachutes. When the ejection device pushes the push plate 2 towards the hatch, the push plate 2 may tilt due to uneven force, causing a certain point of the push plate 2 to collide with the inner wall of the parachute compartment, thus jamming the push plate 2. In addition, after the push plate 2 separates from the parachute, it is prone to shaking, causing it to collide with the inner wall of the parachute compartment, damaging the push plate 2 and the inner wall of the parachute compartment, and affecting its service life.

[0027] To address this issue, this embodiment proposes a UAV parachute compartment, referencing... Figure 1 The system includes a parachute compartment body 1 for installing and releasing a parachute. The parachute compartment body 1 has a receiving cavity 11 for installing the parachute. The upper end of the parachute compartment body 1 has a hatch, and a hatch cover 12 is installed at the hatch. Applying a certain force to the hatch cover 12 inside the parachute compartment body 1 can open the hatch cover 12 so that the parachute can be pushed out of the hatch.

[0028] For details, please refer to Figure 1An ejection assembly is provided at the bottom of the parachute compartment body 1, with the output end of the ejection assembly facing the hatch, for ejecting the parachute out of the hatch. A push plate 2 is connected to the upper end (i.e. the output end) of the ejection assembly, and the parachute is installed on the upper end of the push plate 2. At least one opposite side of the push plate 2 is provided with an extension, which extends to the inner wall of the parachute compartment body 1 and abuts against the inner wall of the parachute compartment body 1. When the extension is controlled to move, it can reciprocate along the inner wall of the parachute compartment body 1 toward the hatch and the bottom of the compartment.

[0029] When the parachute is opened, the ejection assembly pushes the push plate 2 towards the hatch, which in turn pushes the parachute out of the hatch. During the movement of the push plate 2, the extension moves closely against the inner wall of the parachute compartment body 1.

[0030] This embodiment provides extensions on at least one opposite side of the push plate 2, extending the extensions to abut against the inner wall of the parachute compartment body 1, thereby limiting the push plate 2 and reducing the shaking that occurs when the push plate 2 is pushed by the ejection assembly. At the same time, since the push plate 2 is limited by the inner wall of the parachute compartment body 1 and plays a guiding role, the push plate 2 moves smoothly during the pushing process, thereby preventing the inner wall of the parachute compartment body 1 from jamming the push plate 2 and affecting the opening of the parachute. In addition, the extensions can also increase the...

[0031] In detail, the ejection assembly serves to drive the push plate 2 to push the parachute out of the hatch, and its specific structure is not limited. Optionally, in one embodiment, the ejection assembly includes an elastic element and a locking element. The elastic element is installed between the push plate 2 and the bottom of the parachute compartment body 1, with its two ends abutting against the bottom of the push plate 2 and the bottom of the parachute compartment body 1, respectively. The locking element is used to fix the push plate 2. When the push plate 2 moves towards the bottom of the compartment, the locking element locks the push plate 2. During the movement of the push plate 2 towards the bottom of the compartment, the elastic element is compressed. When the locking element releases the locking state with the push plate 2, the push plate 2 moves towards the hatch under the action of the elastic element, thereby pushing the parachute installed on the upper end of the push plate 2 out of the hatch.

[0032] It should be understood that two or more extensions can be provided, symmetrically arranged around the push plate 2. In special cases, extensions are provided along the periphery of the push plate 2, so that the push plate 2 and the extensions form an integral plate, and the periphery of the plate is attached to the inner wall of the parachute body 1, changing with the shape of the parachute body 1.

[0033] Preferably, refer to Figure 2 The extension section has four parts, which are fixedly connected to the push plate 2 in a cross-shaped symmetrical manner. While achieving the expected guiding effect, it also prevents the push plate 2 from being too heavy due to too many extension sections, thus increasing the load on the drone.

[0034] Preferably, such as Figures 1 to 2As shown, the extension includes a connecting plate 21. A guide groove 4, extending from the bottom of the canopy towards the hatch, is provided on the inner wall of the canopy body 1 at a corresponding location on the connecting plate 21. One end of the connecting plate 21 is fixedly connected to the push plate 2, and the connecting plate 21 and the push plate 2 are integrally formed. The other end of the connecting plate 21 is embedded in the guide groove 4 and slidably connected to the inner wall of the canopy body 1. The guide groove 4 limits and guides the connecting plate 21, allowing the connecting column to slide smoothly within the guide groove 4, further preventing shaking or jamming during the movement of the push plate 2.

[0035] In one embodiment, reference Figure 2 The guide groove 4 is composed of two parallel first limiting plates 41. One end of each first limiting plate 41 is fixedly connected to the inner wall of the parachute compartment body 1, and the first limiting plate 41 can be integrally formed with the parachute compartment body 1. By adding limiting plates 41 to the inner wall of the parachute compartment body, the guide groove 4 is formed for guidance, and the parachute compartment body 1 is also reinforced, which is equivalent to acting as a reinforcing rib. It also helps to keep the wall thickness of the parachute compartment body 1 relatively thin and reduce the overall weight.

[0036] Furthermore, for the stability of the overall structure of the parachute compartment, refer to Figure 3 A support plate 6 is fixedly connected to the bottom of the parachute compartment body 1. A push plate 2 is positioned above the support plate 6. A surrounding plate 5 is provided around the push plate 2 and connecting plate 21 on the upper end of the support plate 6, with the end of the surrounding plate 5 away from the push plate 2 connected to the first limiting plate 41, making the first limiting plate 41 and the surrounding plate 5 a whole. When the push plate 2 abuts against the upper end of the support plate 6, the push plate 2 and connecting plate 21 are embedded in the space formed by the surrounding plate 5. The whole formed by the surrounding plate 5 and the first limiting plate 41 strengthens the structural strength of the parachute compartment body and, to a certain extent, limits and restricts the push plate 2, causing it to move towards the hatch in a specific direction, increasing the stability of the ejection assembly and the ejection process of the push plate 2.

[0037] Preferably, refer to Figure 1 and Figure 4 A guide plate 22 is fixedly connected to the end of the connecting plate 21 away from the push plate 2. The guide plate 22 is embedded in the guide groove 4 and abuts against the inner wall of the parachute body 1, allowing it to slide relative to the guide groove 4. By increasing the contact area with the guide groove 4 through the guide plate 22, the guiding effect on the connecting plate 21 is enhanced. At the same time, by limiting the position of the guide plate 22, the tilting angle between the push plate 2 and the connecting plates 21 on its opposite sides is reduced, thereby making the movement of the push plate 2 more stable and preventing jamming. The guide plate 22 also serves to reinforce the connecting plate 21.

[0038] In a preferred embodiment, reference Figure 1 and Figure 4The connecting plate 21 has an arc-shaped guide part 23 at the end away from the push plate 2. When the thrust on the push plate 2 is not in the center of the push plate, the connecting plates 21 on both sides of the push plate 2 will be at different heights, which can easily cause the connecting plate 21 to get stuck on the inner wall of the parachute body 1. However, the guiding effect of the arc-shaped guide part 23 can avoid the jamming situation to a certain extent.

[0039] Understandably, since the parachute requires a significant force to be ejected from the hatch, the ejection assembly exerts a relatively large force on the push plate 2. To increase the service life of the push plate 2 and prevent breakage at the connection between the push plate 2 and the extension during ejection, refer to... Figure 2 and Figure 4 Therefore, at least one reinforcing rib 24 is provided at the connection between each extension and the push plate 2.

[0040] Further, refer to Figure 3 The support plate 6 has a mounting groove 31 at its bottom. The ejection assembly includes a spring 3, which is installed in the mounting groove 31. The upper end of the spring 3 is connected to the push plate 2. The mounting groove 31 guides the spring 3, causing it to eject in a fixed direction. This prevents the direction of the force exerted by the spring 3 on the push plate 2 from changing during ejection, which could cause uneven force on the push plate 2 and tilting, resulting in jamming and affecting the ejection of the parachute.

[0041] Furthermore, refer to Figure 3 The support plate 6 is provided with a second limiting plate 32 around the mounting groove 31, and the lower end of the parachute push plate 2 is provided with a clearance groove. When the push plate 2 abuts against the support plate 6, the third limiting groove is embedded in the clearance groove. The third limiting part further strengthens the limiting effect on the spring 3, making its movement direction more stable.

[0042] The technical solution of this utility model provides extensions on at least one opposite side of the push plate 2. These extensions abut against the inner wall of the parachute compartment body 1, thereby limiting the push plate 2 and reducing the shaking that occurs when the push plate 2 is pushed by the ejection assembly. At the same time, by allowing the extensions to reciprocate along the inner wall of the parachute compartment body 1 toward the hatch and the bottom of the compartment, the parachute is pushed out of the hatch. Since the push plate 2 is limited by the inner wall of the parachute compartment body 1 and guides the push plate 2, the push plate 2 moves smoothly during the pushing process, thereby preventing the inner wall of the parachute compartment body 1 from jamming the push plate 2 and affecting the opening of the parachute.

[0043] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
