Description

Technical Field

[0001] This utility model relates to the technical field of coaxial dual-rotor drone supporting equipment, and in particular to a drone mounting mechanism and a drone. Background Technology

[0002] In the fields of drones, firefighting, rescue, and special operations, the ability to quickly release payloads via catapult is a critical requirement.

[0003] Existing technologies (such as the payload, mounting mechanism, and UAV of CN222934087U) with dual-tube ejection structures only have a limiting hole and sliding pin in one tube arm, while the other tube arm is a sealed cavity structure. Because the ejected dual tubes are independent parts mounted on a fixed frame, gaps arise from the flatness of the tube bottom surfaces and installation fit errors, resulting in parallelism errors between the two tubes. This causes lateral contact friction when the limiting pin slides relative to the limiting hole, leading to an unbalanced force on the dual tubes during ejection and a failure to eject completely. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mounting mechanism and a drone for drones, which can compensate for errors and thus ensure that the dual tubes pop out smoothly and synchronously, thereby releasing the mounted object steadily.

[0005] The technical solution of this utility model is as follows: This utility model discloses a mounting mechanism for a drone and a drone. On one hand, this utility model discloses a mounting mechanism for a drone, including an upper mounting part, including a first mounting part and two sets of limiting sleeves arranged side by side at the bottom of the first mounting part, wherein the limiting sleeves are provided with connecting holes. The lower mounting component includes a locking seat and two sets of pop-out tubes disposed on the locking seat. The pop-out tubes are sleeved in the limiting sleeve and slide in cooperation with the connecting hole, and are used to cooperate with the upper mounting component to achieve limiting. The rotating assembly includes a rotary motor and a torque hook connected to the output end of the rotary motor. The torque hook is arranged in parallel with the limiting sleeve. The torque hook is provided with a hanging groove facing outwards, which is used to cooperate with the load to achieve loading.

[0006] As can be seen from the above solution, this utility model achieves the limiting and clamping of the mounted object through the lower mounting component and the torque hook. The upper mounting component is assembled with the pop-out tube through the limiting sleeve. The torque hook is used to transmit a large torque. The torque hook is used to hang the mounted object through the hanging groove. The rotating component drives the torque hook to rotate through a rotary motor, thereby releasing the mounted component without manual removal. The lower mounting component adopts a parallel sliding and limiting double-tube pop-out structure. This increases the fit clearance between the two pop-out tubes and the tube wall, offsetting the imbalance of frictional resistance caused by the parallelism error between the two tubes, allowing the two tubes to pop out smoothly in parallel, greatly reducing the failure rate and improving the reliability of the product.

[0007] The torque hook includes a limiting gear and a hook limiting member that engages with the limiting gear via fasteners. The hook limiting member is sleeved on the limiting gear. Therefore, the limiting gear and the hook limiting member work together to attach the load.

[0008] The hook limiting component includes a connecting part and a hanging part. The connecting part has an internal gear hole, and the hanging part has a mounting groove. The mounting groove communicates with the internal gear hole through a through hole, the diameter of which is smaller than the diameter of the mounting groove. Therefore, the internal gear hole is adapted to the limiting gear, driving the hook limiting component to rotate via the limiting gear. The internal gear hole and the through hole are used to fix the hook limiting component to the output end of the rotary motor, achieving a direct-drive connection. The mounting groove is used for assembling the hook limiting component with the limiting gear using fasteners.

[0009] The inner wall of the internal gear hole is provided with gear grooves that are adapted to the limiting gear. Therefore, the internal gear hole engages with the limiting gear through the gear grooves.

[0010] A pin is provided on the outer wall of the ejector tube, and a limiting groove is provided along the axis on the wall of the limiting sleeve. The pin passes through the limiting groove and connects to the ejector tube, and the pin slides within the limiting groove. Therefore, the pin slides within the limiting groove to guide the ejector tube out of the limiting sleeve. By providing limiting grooves in two sets of limiting sleeves and using a pin that slides within the limiting groove, the ejector tube can eject smoothly and parallel.

[0011] A spring is provided between the limiting sleeve and the ejector tube. A limiting protrusion is provided inside the limiting sleeve. One end of the spring is fitted onto the limiting protrusion and abuts against the inner wall of the limiting sleeve, while the other end is disposed within the limiting hole of the ejector tube. Therefore, the limiting protrusion is used for the mounting and positioning of the spring top, the spring is used for the connection of the ejector tube within the limiting sleeve, and the spring is used to increase the thrust of the ejector tube within the limiting sleeve.

[0012] On the other hand, this utility model also discloses a drone, including a drone body, with the mounting mechanism provided on both sides of the drone body, the upper mounting component being connected to the drone body via a connecting arm, and the two sets of mounting mechanisms being arranged on the drone body facing opposite directions.

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1 to 8 As shown, this utility model is a mounting mechanism for a drone and a drone, including an upper mounting component 2. The upper mounting component 2 includes a first mounting part 21 and two sets of limiting sleeves 22 arranged side by side at the bottom of the first mounting part 21. The limiting sleeves 22 are provided with connecting holes 221, and the bottom of the limiting sleeves 22 is provided with an opening 222 communicating with the connecting holes 221. The lower mounting component 3 includes a locking seat 31 and two sets of pop-out tubes 32 disposed on the locking seat 31. The pop-out tubes 32 are sleeved in the limiting sleeve 22 and slide in cooperation with the connecting hole 221, and are used to cooperate with the upper mounting component 2 to achieve limiting. The rotating assembly includes a rotary motor 4 and a torque hook 5 connected to the output end of the rotary motor 4. The rotary motor 4 is disposed in the first mounting part 21, and the torque hook 5 is disposed at the bottom of the first mounting part 21. The torque hook 5 is arranged side by side with the limiting sleeve 22. The torque hook 5 is provided with a hanging groove 50, which faces outward and away from the limiting sleeve 22, and is used to cooperate with the load to achieve loading.

[0016] In this embodiment, the first mounting part 21 includes a mounting plate and a limiting shell disposed on the mounting plate. The rotary motor 4 is disposed inside the limiting shell, and the limiting sleeve 22 is disposed at the bottom of the mounting plate. The reference numeral for the UAV is 100. The payload includes a grenade 200 and a safety pin 210 disposed on the grenade 200. When the UAV mounts the grenade 200 through the mounting mechanism, one end of the safety pin 10 is connected to the grenade 200, and the other end is hung in the hanging groove 50 of the torque hook 5. When the rotary motor 4 drives the torque hook 5 to rotate, the torque hook 5 and the safety pin 210 twist relative to each other, which is equivalent to pulling out the grenade safety pin, so that the UAV 100 releases the payload 200 when flying in the air. The locking seat 31 is formed with a semi-enclosed shell adapted to the grenade shell.

[0017] The torque hook 5 includes a limiting gear 51 and a hook limiting member 52 that cooperates with the limiting gear 51 through a fastener 511. The limiting gear 51 is located at the bottom of the first mounting part 21 and is parallel to the limiting sleeve 22. The hook limiting member 52 is sleeved on the limiting gear 51. The hook limiting member 52 includes a connecting part 521 and a hanging part 522. The connecting part 521 is provided with an internal gear hole 523. The hanging part 522 is provided with an outward-facing mounting groove 524. The mounting groove 524 communicates with the internal gear hole 523 through a through hole 525. A partition is integrally formed between the connecting part 521 and the hanging part 522. The through hole 525 is located at the center of the partition, and the diameter of the through hole 525 is smaller than the diameter of the mounting groove 524. In this embodiment, the hook limiting member 52 and the fastener 511 include a head and a columnar part integrally formed with the head. The diameter of the head is larger than the diameter of the columnar part. The head is limited in the mounting groove 524, and the columnar part is inserted into the center hole of the limiting gear 51 through the through hole.

[0018] The inner wall of the internal gear hole 523 is provided with a gear groove 526 that is adapted to the limiting gear 51.

[0019] A pin 33 is provided on the outer wall of the ejector tube 32, and a limiting groove 224 is provided along the axis on the cylinder wall of the limiting sleeve 22. The pin 33 passes through the limiting groove 224 and is connected to the ejector tube 32. The pin 33 is slidably engaged in the limiting groove 224.

[0020] A spring 6 is provided between the limiting sleeve 22 and the pop-out tube 32. A limiting protrusion 223 is provided inside the limiting sleeve 22. One end of the spring 6 is sleeved on the limiting protrusion 223 and abuts against the inner wall of the limiting sleeve 22, and the other end is provided in the limiting hole 321 of the pop-out tube 32.

[0021] This utility model also discloses a drone, including a drone body 100. The drone body 100 has mounting mechanisms on both sides. The upper mounting member 2 is connected to the drone body 100 via a connecting arm 1. The two sets of mounting mechanisms are arranged on the drone body 100 facing opposite directions. In this embodiment, multiple mounting mechanisms can be connected to the connecting arm 1 to mount multiple payloads.

[0022] The working process of this utility model is as follows: When the rotary motor 4 drives the limiting gear 51 to rotate, it drives the hook limiting member 52 to rotate relative to each other, thereby releasing the load. When the load is released, due to gravity, the ejector tube 32 slides along the limiting sleeve 22, and the pin member 33 slides and guides in the limiting groove 224. At the same time, it generates a thrust on the body 31 and increases the thrust through the spring 6 to prevent the body 31 from being obstructed and falling off, thereby realizing the smooth deployment of the UAV.

[0023] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
