Description

Technical Field

[0001] This utility model belongs to the technical field of drones and accessories, and in particular relates to a shock-absorbing and protective frame for drones. Background Technology

[0002] Drones are short for unmanned aircraft. They are unmanned aircraft operated by radio remote control equipment and onboard program control devices. They are widely used in military, aerial photography, agriculture, plant protection, express delivery, disaster relief and other fields. In order to avoid damage to the internal components of drones due to excessive shock force when they land, protective frames are usually installed on drones to reduce the shock force when they land.

[0003] A shock-absorbing and protective frame for a drone is disclosed in a document with the existing authorization announcement number CN216424741U. The frame includes a drone body, with rotors fixedly connected to all four sides of the drone body. Shock-absorbing plates are fixedly connected to the top and bottom of the connection between the rotors and the drone body, and the shock-absorbing plates are fixedly connected to the drone body. Fixed plates are fixedly connected to the bottom two sides of the drone body, and a cavity is opened below the fixed plates. A rotating shaft is fixedly connected to the inner wall of the cavity at a relative position. A connecting plate is rotatably installed at the end of the rotating shaft away from the inner wall of the cavity. A torsion spring is sleeved on the rotating shaft. An arc-shaped support leg is fixedly connected to the bottom of the connecting plate.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The above-mentioned drone shock absorption and protection frame has its arc-shaped legs installed on the drone body through a pivot and connecting plate. The arc-shaped legs and shock absorption mechanism work together to provide shock absorption and protection for the drone body when it lands. However, it is not convenient to quickly install the arc-shaped legs and shock absorption mechanism on the drone body during use.

[0006] 2. The above-mentioned drone shock absorption and protection frame includes a limiting sleeve and a movable rod as its shock absorption mechanism. The shock absorption and protection of the drone body during landing is achieved through the movable connection between the limiting sleeve and the movable rod. However, in use, it is not convenient to adjust the shock absorption intensity of the drone body. The low shock absorption intensity results in poor protection of the drone body, or the high shock absorption intensity results in severe shaking of the drone body during landing.

[0007] To address these issues, we provide a shock-absorbing and protective frame for drones. Utility Model Content

[0008] The purpose of this utility model is to provide a shock-absorbing and protective frame for drones. The mounting plate and shock-absorbing structure are fixed to the drone body by the outer and inner clamping blocks, and the outer and inner clamping blocks are fixed to the legs of drone bodies of different sizes by the abutment rod. This solves the problem of the existing protective frame being inconvenient to install on the drone body. At the same time, the adjustment plate is driven to move by the threaded rod, and the initial deformation of the shock-absorbing spring is adjusted by the adjustment plate, which solves the problem of the existing shock-absorbing strength being inconvenient to adjust.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a shock-absorbing and protective frame for drones, including a drone body, a mounting plate on the legs of the drone body via a mounting component, and a shock-absorbing component on the mounting plate.

[0011] The mounting components include an outer clamp and an inner clamp located on the outer and inner sides of the outriggers of the drone body, respectively. The outer clamp and the inner clamp on the same outrigger of the drone body are fixedly connected to each other. Abutment rods are threaded through the outer walls of both the outer clamp and the inner clamp. A first nut is fixedly connected to one end of the abutment rod, and the other end of the abutment rod is abutted against the outrigger of the drone body.

[0012] The shock-absorbing assembly includes a housing fixedly connected to a mounting plate. A threaded rod is threaded through the top of the housing. A second nut is fixedly connected to the top of the threaded rod. The bottom of the threaded rod extends into the upper interior of the housing and is fixedly connected to an adjusting plate. A movable rod is movably connected through the bottom of the housing. A support plate is fixedly connected to the bottom of the movable rod. The top of the movable rod extends into the lower interior of the housing and is fixedly connected to a movable plate. A shock-absorbing spring is fixedly connected between the adjusting plate and the movable plate.

[0013] A further feature of this invention is that: a first ear seat is fixedly connected to the back surface of each of the front and rear adjacent outer clamping blocks, and a second ear seat is fixedly connected to the back surface of each of the front and rear adjacent inner clamping blocks. A fixing rod is rotatably connected inside the first ear seat, and the end of the fixing rod away from the first ear seat moves through the second ear seat and is threaded with a fastening nut.

[0014] A further feature of this invention is that: positioning holes are provided around the outer wall of the outer clamping block near the inner clamping block, and positioning posts are fixedly connected around the outer wall of the inner clamping block near the outer clamping block, with the end of the positioning post away from the inner clamping block fitted into the positioning hole with a clearance fit.

[0015] A further feature of this invention is that a sleeve is provided between adjacent outer and inner clamping blocks, and a connecting rod is movably fitted inside the sleeve at both the front and rear ends. The end of the connecting rod located outside the sleeve is fixedly connected to the outer and inner clamping blocks.

[0016] A further feature of this invention is that: mounting rods are fixedly connected to both the front and rear ends of the outer wall of the mounting plate near the outer clamping block, and the end of the mounting rod away from the mounting plate is fixedly connected to the front and rear ends of the outer wall of the outer clamping block near the mounting plate.

[0017] A further feature of this invention is that L-shaped plates are fixedly connected to both the front and rear ends of the outer shell, and the longitudinal support arms of the L-shaped plates are fixedly connected to the mounting plate.

[0018] A further feature of this invention is that a feeding port is provided at the center of the outer wall on the side of the outer shell away from the mounting plate, and a sealing piston is engaged inside the feeding port.

[0019] A further feature of this invention is that a groove is provided on the lower surface of the support plate, and a load-bearing block is fitted and fixed inside the groove.

[0020] This utility model has the following beneficial effects:

[0021] 1. This utility model, by setting up an installation component, first places the outer clamping block and the inner clamping block on the outside and inside of the outriggers of the UAV body, respectively, and rotates the fixing rod so that one end of the fixing rod passes through the second ear on the inner clamping block. The fastening nut is then threaded onto the fixing rod, and the fastening nut is tightly fitted to the outer wall of the second ear away from the first ear. This allows the mounting plate and shock-absorbing structure to be installed on the UAV body, making it easy to install and disassemble, and facilitating shock absorption and protection of the UAV body.

[0022] 2. This utility model, by setting up a shock-absorbing component, rotates the second nut, which drives the threaded rod to rotate, and the threaded rod drives the adjusting plate to rise and fall inside the outer shell. The movement of the adjusting plate realizes the adjustment of the initial deformation of the shock-absorbing spring, which makes it easy to adjust the shock absorption strength of the UAV body according to the needs, and facilitates the shock absorption protection of the UAV body.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this is the first embodiment of the present invention. This embodiment provides a shock-absorbing and protective frame for a drone, including a drone body 1. The legs of the drone body 1 are provided with mounting plates 3 by mounting components 2. The mounting components 2 include an outer clamping block 201, an inner clamping block 202, and an abutment rod 203. The mounting plates 3 and the shock-absorbing structure are fixed to the drone body 1 by the outer clamping block 201 and the inner clamping block 202, and the outer clamping block 201 and the inner clamping block 202 are fixed to the legs of drone bodies 1 of different sizes by the abutment rod 203, which solves the problem that it is inconvenient to install the protective frame on the drone body 1 in the existing system.

[0037] Specifically, the outer clamping block 201 is located on the outside of the leg of the UAV body 1, and the inner clamping block 202 is located on the inside of the leg of the UAV body 1. The outer clamping block 201 and the inner clamping block 202 on the same leg of the UAV body 1 are fixedly connected to each other. The outer walls of the outer clamping block 201 and the inner clamping block 202 are threaded with abutting rods 203. One end of the abutting rod 203 is fixedly connected to a first rotating cap 203a, and the other end of the abutting rod 203 is abutted against the leg of the UAV body 1. The outer clamping block 201 and the inner clamping block 202 are used to fix the mounting plate 3 to the leg of the UAV body 1. The abutting rod 203 is used to fix the outer clamping block 201 and the inner clamping block 202 to the legs of the UAV body 1 with different diameters. The first rotating cap 203a is provided to facilitate the rotation of the abutting rod 203.

[0038] Furthermore, a first ear seat 201a is fixedly connected to the back surface of each of the front and rear adjacent outer clamping blocks 201, and a second ear seat 202a is fixedly connected to the back surface of each of the front and rear adjacent inner clamping blocks 202. A fixing rod 201b is rotatably connected inside the first ear seat 201a, and one end of the fixing rod 201b away from the first ear seat 201a moves through the second ear seat 202a and is threaded with a fastening nut 201c.

[0039] The outer clamping block 201 has positioning holes 201d on all four sides of the outer wall of the side near the inner clamping block 202. The inner clamping block 202 has positioning posts 202b fixedly connected on all four sides of the outer wall of the side near the outer clamping block 201. The end of the positioning post 202b away from the inner clamping block 202 is fitted with a clearance inside the positioning hole 201d.

[0040] A sleeve 204 is provided between adjacent outer clamping blocks 201 and inner clamping blocks 202. A connecting rod 204a is movably sleeved at both the front and rear ends of the sleeve 204. One end of the connecting rod 204a located on the outside of the sleeve 204 is fixedly connected to the outer clamping block 201 and the inner clamping block 202.

[0041] Mounting rods 301 are fixedly connected to the front and rear ends of the outer wall of the mounting plate 3 near the outer clamping block 201. The end of the mounting rod 301 away from the mounting plate 3 is fixedly connected to the front and rear ends of the outer wall of the outer clamping block 201 near the mounting plate 3.

[0042] The operation process of this embodiment is as follows: First, place the outer clamping block 201 and the inner clamping block 202 on the outer and inner sides of the legs of the UAV body 1, respectively, and rotate the fixing rod 201b so that one end of the fixing rod 201b passes through the second ear seat 202a on the inner clamping block 202. Then, thread the fastening nut 201c onto the fixing rod 201b so that the fastening nut 201c is tightly attached to the outer wall of the second ear seat 202a away from the first ear seat 201a, thereby realizing the installation of the mounting plate 3 and the shock absorption structure on the UAV body 1. Example 2

[0043] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a shock-absorbing component 4 is also provided on the mounting plate 3. The shock-absorbing component 4 includes a housing 401, a threaded rod 402, an adjusting plate 403, a movable rod 404, a support plate 405, a movable plate 406, and a shock-absorbing spring 407. The threaded rod 402 drives the adjusting plate 403 to move, and the adjusting plate 403 adjusts the initial deformation of the shock-absorbing spring 407, thus solving the problem of the existing method of not being able to adjust the shock absorption intensity.

[0044] Specifically, the outer casing 401 is fixedly connected to the mounting plate 3. A threaded rod 402 is threaded through the top of the outer casing 401. A second cap 402a is fixedly connected to the top of the threaded rod 402. The bottom end of the threaded rod 402 extends to the upper interior of the outer casing 401 and is fixedly connected to an adjusting plate 403. A movable rod 404 is movably connected to the bottom of the outer casing 401. A support plate 405 is fixedly connected to the bottom of the movable rod 404. The top end of the movable rod 404 extends to the lower interior of the outer casing 401 and is fixedly connected to a movable plate 406. A shock-absorbing spring 407 is fixedly connected between the adjusting plate 403 and the movable plate 406. Damping fluid is also filled between the adjusting plate 403 and the movable plate 406 to dissipate the kinetic potential energy of the movable plate 406.

[0045] Furthermore, L-shaped plates 401a are fixedly connected to both the front and rear ends of the outer casing 401, and the longitudinal support arms of the L-shaped plates 401a are fixedly connected to the mounting plate 3.

[0046] A feeding port 401b is provided at the center of the outer wall on the side away from the mounting plate 3 of the outer casing 401, and a sealing piston 401c is snapped into the inside of the feeding port 401b;

[0047] The lower surface of the support plate 405 has a groove 405a, and a load-bearing block 405b is fitted and fixed inside the groove 405a.

[0048] The rest of the structure is the same as in Example 1.

[0049] The operation process of this embodiment is as follows: Rotate the second nut 402a, which drives the threaded rod 402 to rotate. The threaded rod 402 then drives the adjusting plate 403 to rise and fall inside the outer shell 401. The movement of the adjusting plate 403 adjusts the initial deformation of the shock-absorbing spring 407, thereby adjusting its shock absorption strength. When the UAV body 1 lands, its support plate 405 contacts the ground. At this time, the ground applies an external force to the movable rod 404 through the support plate 405. The movable rod 404 then drives the shock-absorbing spring 407 to move through the movable plate 406. Through the deformation of the shock-absorbing spring 407 and the damping fluid filled inside the outer shell 401, shock absorption protection is achieved for the landing of the UAV body 1.
