Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) accessory technology, and in particular relates to a UAV parachute compartment. Background Technology

[0002] The drone's parachute compartment houses the parachute and its accessories. During mission recovery or in emergencies, the drone needs to deploy its parachute to slow its descent, reducing the risk of damage to the drone and related equipment, as well as any harm to people or property on the ground after landing. The parachute compartment cover seals the opening of the compartment, providing restraint for the parachute and its accessories. It also needs to respond promptly to commands and automatically drop to ensure successful deployment. Furthermore, when the drone is not in recovery mode, the parachute compartment cover must be securely attached to the drone.

[0003] Currently, the primary method for ejecting the parachute canopy cover is the explosive bolt separation method. This involves detonating an explosive bolt to sever the fixed connection between the canopy cover and the canopy body, releasing the cover and allowing it to separate from the drone body under gravity, pressure, or the force of an internal rocket. Currently, the explosive bolt is installed on the drone. One end of the canopy cover has a pre-drilled hole in the middle, which is screwed onto the bolt. The other end has two lugs that insert into pre-drilled guide slots on the drone. When the canopy cover separates, the explosive bolt detonates, severing the fixed connection and releasing the cover, thus separating it from the drone body. However, explosive bolts are single-use, resulting in high costs. Furthermore, as explosive devices, they require strict safety procedures during installation to ensure their safety. Transporting the explosive bolts requires specialized vehicles; storing them requires a qualified facility for storing explosive devices; and installing the explosive bolts requires personnel with professional explosive device handling certifications. All of this significantly increases the manufacturing and assembly costs of the drone. Utility Model Content

[0033] In order to describe this utility model in detail, the following is a specific description of a drone parachute compartment according to this utility model:

[0034] Please combine Figures 1 to 7As shown, this utility model provides a drone parachute compartment, including a parachute compartment body 1, a parachute compartment body cover 3, and a locking assembly 4. The parachute compartment body 1 has a receiving cavity for accommodating the parachute pack and a parachute compartment body opening for opening the parachute (not shown in the figures), and the parachute compartment body opening communicates with the receiving cavity. The parachute compartment body cover 3 covers the parachute compartment body opening to seal the receiving cavity. The locking assembly 4 is disposed between the parachute compartment body 1 and the parachute compartment body cover 3. The locking assembly 4 includes a latch 403, a locking fixing seat 404, and a locking member 402 movably disposed on the locking fixing seat 404. The locking member 402 has a locking position and an unlocking position. When the locking member 402 is in the locked position, the locking member 402 is close to the latch 403, and the locking member 402 and the latch 403 are locked to connect the umbrella compartment body cover 3 to the umbrella compartment body 1. When the locking member 402 is in the unlocked position, the locking member 402 and the latch 403 are unlocked to disengage the umbrella compartment body cover 3 from the umbrella compartment body 1. The latch 403 is provided on the umbrella compartment body 1, and the locking fixing seat 404 and the latch 403 are provided on the umbrella compartment body cover 3; or, the locking fixing seat 404 and the latch 403 are provided on the umbrella compartment body 1, and the latch 403 is provided on the umbrella compartment body cover 3. By setting a locking component 4 between the parachute compartment body 1 and the parachute compartment body cover 3, and locking and unlocking by locking element 402 and latch 403, the parachute compartment body cover 3 can be detached from the parachute compartment body 1 by unlocking the locking element 402 and latch 403 when the drone is recovered from a mission or encounters an emergency. During the normal use of the drone, the parachute compartment body cover 3 is connected to the parachute compartment body 1 by locking element 402 and latch 403. This eliminates the need for explosive bolt separation to separate the parachute compartment body cover 3 from the parachute compartment body 1, reducing the cost of drone manufacturing and assembly, and improving safety during use.

[0035] It should be noted that, Figure 1 and Figure 3 The diagram only shows a portion of the parachute compartment 1; the entire parachute compartment 1 is not shown. Figure 1 and Figure 3 The parachute compartment body 1 in the middle section only becomes the complete parachute compartment body 1 after it is combined with the skin on the UAV. For the sake of explanation in this application, the parachute compartment body 1 will be... Figure 1 and Figure 3 The partial parachute compartment body 1 is labeled as parachute compartment body 1.

[0036] When the parachute compartment cover 3 covers the opening of the parachute compartment body, the locking component 4 is located inside the receiving cavity. Placing the locking component 4 inside the receiving cavity can prevent the drone from being affected by the external environment during use and accidentally triggering the locking component 4 to unlock, causing the parachute compartment cover 3 to separate from the parachute compartment body 1, thus affecting the stability of the drone's use. In some embodiments, the locking component 4 is located on the outer surface of the parachute compartment body 1 and the parachute compartment cover 3.

[0037] like Figure 2As shown, the latch 403 and the locking element 402 are locked together by a locking structure. The locking and unlocking mechanism facilitates assembly and production.

[0038] Specifically, the locking structure includes an insertion part and a blocking part 4031. The insertion part is located on the locking member 402, and the blocking part 4031 is located on the latch 403; or the insertion part is located on the latch 403, and the blocking part 4031 is located on the locking member 402. The blocking part 4031 has a passage opening 4032, which is located on the movement trajectory of the insertion part, and at least part of the insertion part enters the blocking part 4031 through the passage opening 4032. When the locking member 402 is in the locked position, the blocking part 4031 prevents the insertion part from moving along a first direction to prevent the parachute body cover 3 from separating from the parachute body 1. The first direction is the direction in which the parachute body cover 3 is closed on the parachute body 1.

[0039] In this embodiment, the locking member 402 includes a transmission rod 4022, a linkage rod 4021, and an actuating rod 4023. The linkage rod 4021 is movably mounted on the locking fixing seat 404 along a second direction. The transmission rod 4022 and the actuating rod 4023 are respectively connected to the linkage rod 4021. The transmission rod 4022 extends along a first direction, and the actuating rod 4023 extends along a third direction. The first direction, the second direction, and the third direction are all perpendicular to each other. The second direction is the line direction connecting the locked position and the unlocked position of the locking member 402. The transmission rod 4022 is used to push the linkage rod 4021 to move with the aid of external force, and the insertion part is located at the end of the actuating rod 4023. The blocking part 4031 is located on the latch 403. The latch 403 is plate-shaped. The blocking part 4031 of the latch 403 has a snap-fit ​​groove 4033 extending in the second direction. The snap-fit ​​groove 4033 passes through both sides of the latch 403. The snap-fit ​​groove 4033 has a through port 4032 for the insertion part. The through port 4032 communicates with the snap-fit ​​groove 4033. The insertion part enters the snap-fit ​​groove 4033 through the through port 4032. The extension direction of the insertion part of the actuating rod 4023 is perpendicular to the orientation of the through port 4032.

[0040] In some embodiments, the locking structure includes a limiting hole and an entry portion for insertion into the limiting hole. The opening of the limiting hole is the aforementioned through port 4032. The entry portion is inserted into the limiting hole through port 4032. When the limiting hole is located on the latch 403, the entry portion is located on the locking member 402. The hole of the limiting hole extends in the second direction. The entry portion is rod-shaped. One end of the action rod 4023 of the locking member 402 is connected to the linkage rod 4021. The other end of the action rod 4023 of the locking member 402 is provided with an entry portion extending in the second direction. When the locking member 402 is in the locked position, the entry portion is inserted into the limiting hole. When the locking member 402 is in the unlocked position, the entry portion is outside the limiting hole.

[0041] like Figure 2 and Figure 5 As shown, an elastic element 401 is provided between the locking base 404 and the locking member 402. The elastic element 401 is used to drive the locking member 402 back to the locked position. By providing the elastic element 401, the locking member 402 can automatically return to the locked position under the action of the elastic element 401, maintaining the locked state of the locking assembly 4. In this embodiment, the elastic element 401 is a spring. One end of the spring is connected to the locking base 404, and the other end of the spring is connected to the locking member 402. The spring is sleeved on the linkage rod 4021. The opening 4032 is arranged in the second direction away from the spring. When the locking member 402 is in the locked position, the spring is in a compressed state. In some embodiments, the opening 4032 can be arranged in the second direction closer to the spring.

[0042] The locking member 402 includes a linkage rod 4021. A limiting hole is provided on the locking base 404 to limit the movement direction of the linkage rod 4021. The linkage rod 4021 passes through the limiting hole and can reciprocate along the hole. By providing the limiting hole, the movement direction of the locking member 402 can be limited. In this embodiment, the limiting hole extends along a second direction. The locking base 404 includes two limiting portions 4041 arranged sequentially along the second direction. Each limiting portion 4041 has a limiting hole. The linkage rod 4021 passes through the limiting hole. An actuating rod 4023 is arranged along the second direction outside the line connecting the two limiting portions 4041 of the linkage rod 4021. A transmission rod 4022 is arranged along the second direction between the two limiting portions 4041 of the linkage rod 4021. One end of a spring abuts against the transmission rod 4022, and the other end of the spring is connected to one of the two limiting portions 4041.

[0043] like Figure 7 As shown, the umbrella canopy cover 3 has a covering portion 302 that covers the opening of the umbrella canopy body 1. The covering portion 302 is disposed corresponding to the edge of the opening of the umbrella canopy body. That is, the umbrella canopy cover 3 includes the covering portion 302 and a shielding portion 301 that matches the size of the opening of the umbrella canopy body. The projection of the shielding portion 301 in the first direction is approximately coincident with the projection of the opening of the umbrella canopy body in the first direction. The covering portion 302 is disposed around the edge of the shielding portion 301. By providing the covering portion 302, the umbrella canopy cover 3 can better seal the umbrella canopy body 1. At the same time, when the locking assembly 4 locks the umbrella canopy body 1 and the umbrella canopy cover 3, the covering portion 302 can prevent the umbrella canopy cover 3 from entering the receiving cavity of the umbrella canopy body 1, thereby improving the stability of the umbrella canopy body 1 during use.

[0044] The umbrella canopy cover 3 has an insert 5 on the side facing the receiving cavity. The insert 5 corresponds to the opening of the umbrella canopy body. The insert 5 includes a support part 502 and an insertion part 501. The insertion part 501 is elongated. One end of the insertion part 501 is connected to the support part 502, and the other end is used for detachable connection with the umbrella canopy body 1. The umbrella canopy body 1 has a strip-shaped receiving groove for accommodating the insertion part 501. One end of the receiving groove has an inlet for inserting the insertion part 501. The insertion part 501 enters the receiving groove through the inlet to limit the position of the umbrella canopy cover 3 relative to the umbrella canopy body. In this embodiment, only one locking assembly 4 is provided on the umbrella canopy. The umbrella canopy cover 3 has two inserts 5. The insertion parts of the two inserts 5 extend in a third direction away from the locking assembly 4. The locking assembly 4 and the two inserts 5 are arranged in a third direction on opposite sides of the umbrella canopy cover 3. By providing two lugs 5 on the canopy cover 3, the stability of the canopy cover 3 installed on the canopy body 1 can be increased. When the locking component 4 is in the unlocked state, there will be an open opening between the canopy cover 3 and the canopy body 1. At this time, due to the weight of the canopy cover 3 and the change in air pressure inside and outside the canopy cover 3, the position between the canopy cover 3 and the lugs 5 will change, and the connection between the lugs 5 and the canopy body 1 will fail, thereby causing the canopy cover 3 to detach from the canopy body 1. In this embodiment, the canopy cover 3 is square, and the side without the lugs 5 and the locking component 4 is provided with a covering part 302.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, the UAV parachute compartment includes a drive component, which drives the locking component 402 to move. The drive component is mounted on the parachute compartment cover 3 or on the parachute compartment body 1. In this embodiment, the drive component is a servo motor 2, which includes a servo head 201 and a rocker arm 202. The rocker arm 202 is rotatably mounted on the servo head 201, and a drive rod 203 is mounted on the rocker arm 202. The servo motor 2 drives the drive rod 203 to move through the rocker arm 202. The drive rod 203 is in contact with a transmission rod 4022. The drive rod 203 extends along a third direction, and the transmission rod 4022 extends along a first direction. The servo motor 2 has advantages such as high-precision positioning and control, large torque output, and fast response speed. In some embodiments, the drive component can be a linear motor, with the drive rod 203 mounted on the output shaft of the linear motor, driving the drive rod 203 to move along the first direction; or the drive component can be a slide, with the drive rod 203 mounted on the moving end of the slide, driving the drive rod 203 to move along the first direction. The type of drive unit can be adjusted according to actual usage needs.

[0046] To ensure that the linkage 4021 does not rotate around its axial direction when it moves in the second direction, a limiting structure is provided on the locking base 404. The limiting structure includes a limiting block 4043 and a limiting groove 4042 formed on the locking base 404. The limiting groove 4042 extends in the second direction, and the limiting block 4043 is slidably disposed in the limiting groove 4042. The limiting block 4043 is connected to the end of the transmission rod 4022 away from the servo motor 2. The extension length of the limiting groove 4042 in the first direction must meet the requirements for the locking member 402 to move between the locked position and the unlocked position.

[0047] In summary, by setting a locking component 4 between the parachute compartment body 1 and the parachute compartment body cover 3, and locking and unlocking it through the locking element 402 and the latch 403, the parachute compartment body cover 3 can be detached from the parachute compartment body 1 by unlocking the locking element 402 and the latch 403 when the drone is recovered from a mission or encounters an emergency. During the normal use of the drone, the parachute compartment body cover 3 is connected to the parachute compartment body 1 by locking the locking element 402 and the latch 403. This eliminates the need for explosive bolts to separate the parachute compartment body cover 3 from the parachute compartment body 1, reducing the cost of drone manufacturing and assembly, and improving safety during use.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
