Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a device and method for simulating UAV launch impact testing. Background Technology

[0002] During launch, drones are subjected to varying degrees of impact overload, including impact overload on the fuselage and onboard equipment during launch, and impact overload on unlaunched drones caused by the launch of other drones during multi-drone launches.

[0003] Impact overload exceeding the structural limits of a drone or its onboard electronic components can lead to problems such as airframe deformation, component loosening, and circuit failure, directly affecting the drone's launch success rate, flight safety, and lifespan. Therefore, conducting launch impact tests on drones before they leave the factory is crucial. By simulating launch impact overloads, the impact resistance of the drone and related components can be effectively verified, providing a basis for optimizing design and improving reliability.

[0004] The existing technology for drone launch impact testing has the following problems: Most impact testing equipment currently used for drones is mainly used to simulate longitudinal overload. However, drones are not only subjected to longitudinal impact during launch, but also to lateral and normal impact. If longitudinal, lateral, and normal overloads exceed the load-bearing range during drone launch, they will directly affect the launch and flight reliability of the drone. Existing impact testing equipment is complex in structure and cumbersome to operate, and the impact overload is fixed, lacking the ability to adapt and adjust according to the impact overload parameters; Launch tubes are important test objects in impact tests, but existing impact testing equipment does not have the function of protecting launch tubes, resulting in a waste of resources. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device and method for simulating the launch impact test of a UAV; The solution adopted by this invention to solve the technical problem is: on the one hand: A simulated UAV launch impact test device includes a ground fixing device, a launch tube fixing device mounted on the ground fixing device for fixing the launch tube, a swing impact device detachably mounted on the launch tube fixing device for applying force to the launch tube, and a protection mechanism mounted on the launch tube fixing device for bearing the force of the swing impact device and transmitting the force to the launch tube; the swing impact device is rotatably engaged with the launch tube fixing device.

[0006] In some possible implementations, the swing impact device includes a rotating mounting plate disposed on the same side as the protection mechanism and mounted on the launch tube fixing device, and an impact hammer that rotates with the rotating mounting plate and is used to apply force to the outside of the protection mechanism.

[0007] In some possible implementations, the impact hammer includes an impact hammer head, a counterweight mounted on the impact hammer head, a hammer handle connected at one end to the impact hammer head and at the other end to a rotating mounting plate, and a locking element for locking the hammer handle to the rotating mounting plate.

[0008] In some possible implementations, a first pin is provided on the rotating mounting plate to rotate with the hammer handle, and a first bearing is provided on the hammer handle to cooperate with the first pin and to be fitted on the outside of the first pin; a slot is provided on the rotating mounting plate to engage with the launching tube fixing device.

[0009] In some possible implementations, the locking element includes a second bearing disposed on the hammer handle, a second pin disposed on the rotating mounting plate and fitted inside the second bearing, and a plurality of limiting holes disposed on the rotating mounting plate for mounting the second pin; the center of the plurality of limiting holes is equidistant from the axis of the first pin and the distance between adjacent sets of limiting holes is equidistant.

[0010] In some possible implementations, the rotating mounting plate is located directly above the protection mechanism; the center of the impact hammer near the end of the protection mechanism and the center of the protection mechanism are equidistant from the axis of the first pin.

[0011] In some possible implementations, the launch tube fixing device includes a support frame with a mounting groove and mounted on a ground fixing device, and a fixing pressure plate mounted on the support frame and vertically limiting the launch tube.

[0012] In some possible implementations, a connecting mechanism for connecting the support frame and achieving a rigid or flexible connection is provided on the ground fixing device, and a shock-absorbing pad and a counterweight are provided at the bottom of the ground fixing device.

[0013] In some possible implementations, the protective mechanism includes an impact frame disposed in a mounting slot and an impact plate mounted on the side of the impact frame away from the mounting slot and used in conjunction with the swinging impact device, the center of the impact plate being on the swinging trajectory of the swinging impact device.

[0014] on the other hand: A method for simulating a drone launch impact test, based on the aforementioned drone launch impact test equipment, specifically includes the following steps: According to the test requirements, the ground fixing device and the launching tube fixing device are connected using different connection mechanisms; the weight of the swing impact device and its relative position with the protection mechanism are adjusted according to the test requirements. The launch tube is installed so that the inner side of the protective mechanism is in contact with and fits against the launch tube; Release the limit between the swing impact device and the launching tube fixing device, the swing impact device rotates, and applies force to the outer side of the protection mechanism. The protection mechanism then transmits the impact force it is subjected to to the launching tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention can effectively simulate the impact overload generated during the launch of a UAV using testing equipment, and verify whether the UAV structure and onboard equipment meet the launch conditions. This invention achieves different impact effects by using a rotating mounting plate, impact hammer, and counterweights, and by increasing or decreasing the number of counterweights on the impact hammer and changing the release angle of the impact hammer. This invention selects different connection mechanisms according to the test requirements to adjust the frequency of impact vibration during the test, thereby simulating the launch overload state. This invention effectively limits the launch tube in both the horizontal and vertical directions through the cooperation of a fixed pressure plate and a protective mechanism. At the same time, the protective mechanism can also prevent damage to the launch tube and deformation of the impact hammer during impact. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0018] The present invention will now be described in detail.

[0019] on the one hand: like Figures 1-4 As shown, a simulated UAV launch impact test device is used to simulate the impact overload generated during the launch of a UAV and to verify whether the UAV structure and onboard equipment meet the launch conditions. It includes a ground fixing device 1, a launch tube fixing device 2 installed on the ground fixing device 1 for fixing the launch tube 100, a swing impact device 3 detachably installed on the launch tube fixing device 2 for applying force to the launch tube 100, and a protection mechanism 4 installed on the launch tube fixing device 2 for bearing the force of the swing impact device 3 and transmitting the force to the launch tube 100. The swing impact device 3 is rotatably engaged with the launch tube fixing device 2, and its rotation axis is parallel to the axis of the launch tube 100.

[0020] Specifically, during use, the launch tube 100 is installed on the launch tube fixing device 2, and the launch tube 100 is limited in the vertical direction and axial direction. The position of the protection mechanism 4 is adjusted so that the inner side of the protection mechanism 4 abuts against the launch tube 100 for limiting. The position of the swing impact device 3 relative to the swing impact device 3 and its own weight are adjusted according to the impact overload required by the test. During the test, the swing impact device 3 rotates from the top of the protection mechanism 4 towards the side closer to the protection mechanism 4 and applies a force to the side of the protection mechanism 4 away from the launch tube 100. The force is transmitted to the launch tube 100 through the protection mechanism 4 to realize the impact test simulation.

[0021] In some possible implementations, in order to effectively apply force to the protection mechanism 4 through the swing impact device 3 and enable the force to be adjusted according to the magnitude of the impact overload, the swing impact device 3 includes a rotating mounting plate 31 disposed on the same side as the protection mechanism 4 and mounted on the launch tube fixing device 2, and an impact hammer 32 rotatably engaged with the rotating mounting plate 31 and used to apply force to the outside of the protection mechanism 4.

[0022] Specifically, adjusting the height of the impact hammer 32 will adjust the magnitude of the force applied by the impact hammer 32 to the protection mechanism 4. For example, if the impact overload requirement is large, the distance between the impact hammer 32 and the protection mechanism 4 will be increased. Because the rotating mounting plate 31 and the impact hammer 32 are in rotational engagement, a greater distance between the impact hammer 32 and the protection mechanism 4 causes the impact hammer 32 to rotate around its axis of rotation with the rotating mounting plate 31 towards the side closer to the protection mechanism 4 when striking it, thus applying a force to the protection mechanism 4. Figure 4 As shown, during the test, the impact hammer 32 rotates clockwise toward the side closer to the protection mechanism 4 and strikes the protection mechanism 4.

[0023] In some possible embodiments, the impact hammer 32 includes an impact hammer head 321, a counterweight 322 mounted on the impact hammer head 321, a hammer handle 323 connected at one end to the impact hammer head 321 and at the other end to the rotating mounting plate 31, and a locking member 33 for locking the hammer handle 323 and the rotating mounting plate 31; the axis of rotation of the relative rotation of the hammer handle 323 and the rotating mounting plate 31 is set along the axial direction of the launching tube 100; Specifically, before the test, to prevent the impact hammer head 321 from shaking randomly, the locking component 33 is used to lock and fix the hammer handle 323 to the rotating mounting plate 31; of course, before the test, the impact hammer head 321 and the rotating mounting plate 31 also need to be locked; the setting of the counterweight block 322 will realize the adjustment of the weight of the impact hammer head 321. Through the rotational cooperation between the impact hammer head 321 and the rotating mounting plate 31, and the adjustment of the weight of the impact hammer head 321, the hammering force on the protection mechanism 4 will be effectively adjusted. Furthermore, each set of counterweights 322 weighs 2kg, and holes are provided on each set of counterweights 322. The counterweights 322 are installed by engaging screws through the holes. Furthermore, the impact hammer head 321 is cylindrical, the hammer handle 323 is connected to the outer side of the impact hammer head 321, and the counterweight block 322 is detachably installed on the top surface of the impact hammer head 321, and its bottom surface will serve as the surface on which the force is applied to the protection mechanism 4.

[0024] In some possible implementations, in order to effectively achieve the rotational engagement between the hammer handle 323 and the rotating mounting plate 31, a first pin 312 is provided on the rotating mounting plate 31 to rotate with the hammer handle 323 and to be arranged axially along the launch tube 100; a first bearing 3231 is provided on the hammer handle 323 to engage with the first pin 312 and to be fitted onto the outside of the first pin 312; and a slot 311 is provided on the rotating mounting plate 31 to engage with the launch tube fixing device 2. Before the test, the rotating mounting plate 31 is snapped onto the launching tube fixing device 2 through the slot 311, so that it is on the same side as the protection mechanism 4. The first bearing 3231 and the first pin 312 set on the hammer handle 323 can rotate with the rotating mounting plate 31 through the cooperation of the first bearing 3231 and the first pin 312. The rotational cooperation of the first bearing 3231 and the first pin 312 will reduce the friction during rotation.

[0025] In some possible implementations, to effectively lock the hammer handle 323 to the rotating mounting plate 31, the locking member 33 includes a second bearing 331 disposed on the hammer handle 323, a second pin 332 disposed on the rotating mounting plate 31 and fitted inside the second bearing 331, and multiple sets of limiting holes 333 disposed on the rotating mounting plate 31 for mounting the second pin 332. One end of the second pin 332 passes through the limiting hole and is inserted into the second bearing 331, cooperating with the first bearing 3231 to limit the hammer handle 323. The center of the multiple sets of limiting holes 333 is equidistant from the axis of the first pin 312, and the distance between adjacent sets of limiting holes 333 is equidistant. That is, the center of the multiple sets of limiting holes 333 is on the same circle, and the center of this circle is on the axis of the first pin 312. The axes of the first bearing 3231 and the second bearing 331 are on the same plane, and the second bearing 331 is disposed between the first bearing 3231 and the impact hammer head 321.

[0026] Furthermore, both the first bearing 3231 and the second bearing 331 are shoulder bearings; both the first pin 312 and the second pin 332 are quick-release pins. Specifically, the second pin 332 is a set, and the limiting holes 333 are multiple sets. During use, according to the test requirements, the second bearing 331 is adjusted to be coaxial with one set of limiting holes 333. One end of the second pin 332 passes through the limiting hole 333 and the second bearing 331, and cooperates with the first pin 312 to lock and fix the corresponding hammer handle 323. During the test, the second pin 332 is removed first. Under the action of gravity, the hammer handle 323 and the impact hammer head 321 rotate around the first pin 312 towards the side closer to the protection mechanism 4, and apply force to the protection mechanism 4 through the impact hammer head 321. The setting of multiple sets of limiting holes 333 will make the relative position of the impact hammer head 321 and the protection mechanism 4 different when the impact hammer head 321 is locked and fixed with the rotating mounting plate 31, thereby realizing the adjustment of the force.

[0027] Furthermore, there are two sets of rotating mounting plates 31 with identical structures. One end of the hammer handle 323 is positioned between the two sets of rotating mounting plates 31 and rotates in cooperation with the two sets of rotating mounting plates. This arrangement makes the connection more secure.

[0028] In some possible implementations, the rotating mounting plate 31 is located directly above the protective mechanism 4; the center of the impact hammer 321 near the protective mechanism 4 and the center of the protective mechanism 4 are equidistant from the axis of the first pin 312; in use, the impact hammer 321 rotates around the rotation axis of the hammer handle 323 and the rotating mounting plate 31 under the drive of the hammer handle 323. By controlling the impact hammer 321 to be close to the center line of the protective mechanism 4 and the center line of the protective mechanism 4 to be equidistant from the first pin 312, the two centers of the impact hammer 321 will coincide when applying force to the protective mechanism 4, making the force applied to the protective mechanism 4 more uniform, and thus making the force on the launching tube 100 more uniform.

[0029] In some possible implementations, the launch tube fixing device 2 includes a support frame 21 with a mounting groove 211 and mounted on a ground fixing device 1, and a fixing pressure plate 22 mounted on the support frame 21 and vertically limiting the launch tube 100.

[0030] Specifically, the support frame 21 includes a support column connected to the ground fixing device 1, a base frame installed on the support assembly, and a vertical frame 212 installed on the base frame and cooperating with the base frame to form a mounting groove 211; the mounting groove 211 has a U-shaped cross-section and opens upward. The rotating mounting plate 31 and the protective mechanism 4 are installed on one of the vertical frames 212. In order to avoid the installation of the rotating mounting plate 31 and the protective mechanism 4, the vertical height of this set of vertical frames 212 will be higher than that of the other set of vertical frames 212.

[0031] The fixing plate 22 is installed on another set of vertical frames 212. After the launch tube 100 is installed, the bottom of the fixing plate will be in contact with the top of the launch tube 100, thereby limiting the vertical sway of the launch tube 100.

[0032] In some possible implementations, a connecting mechanism 5 for connecting the support frame 21 and achieving a rigid or flexible connection is provided on the ground fixing device 1, and a shock-absorbing pad 11 and a counterweight 12 are provided at the bottom of the ground fixing device 1.

[0033] Specifically, the connecting mechanism 5 can realize a rigid or flexible connection between the ground fixing device 1 and the launching tube fixing device 2. During the test, different connecting mechanisms 5 can be selected for connection according to the usage requirements. The connecting mechanism 5 includes a first fixing plate 51 installed on the ground fixing device 1, and a second fixing plate 52 installed at the bottom of the support frame 21 and connected to the first fixing plate 51; the first fixing plate 51 and the second fixing plate 52 are provided with reinforcing plates connected to the ground fixing device 1 and the support frame 21, thereby reducing the deformation of the first fixing plate 51 and the second fixing plate 52 during the test; When the two are flexibly connected, the connecting mechanism 5 also includes a spring device, a wire rope device, and a rubber column device; furthermore, the fixing device, spring device, wire rope device, and rubber column device are capable of bearing a weight of about 400 kg and undergoing lateral and normal impacts of ≥10 g. When the two are fixedly connected, the first fixing piece 51 and the second fixing piece 52 can be directly connected by bolts.

[0034] Specifically, the shock-absorbing pad 11 installed at the bottom of the ground fixing device 1 will provide a good buffering effect between the ground and the device during the test; the counterweight 12 will prevent the device from moving or even tipping over due to shaking during the test. Furthermore, the shock-absorbing pads 11 are in four groups, evenly arranged at the bottom of the ground fixing device; During the test, different connection mechanisms 5 were selected according to the test requirements to connect the launch tube fixing device 2 with the ground fixing device 1, thereby adjusting the frequency of the impact vibration and simulating the launch overload state.

[0035] In some possible implementations, the protection mechanism 4 includes an impact frame 41 disposed in the mounting groove 211 and an impact plate 42 mounted on the side of the impact frame 41 away from the mounting groove 211 and used in conjunction with the swing impact device 3. The center of the impact plate 42 is on the swing trajectory of the swing impact device 3. Specifically, the impact hammer 321 will make a circular motion around the axis of the first pin 312. Furthermore, the protection mechanism 4 also includes an adjustment device 43 installed on the support frame 21 and connected to the impact frame 41. The positional relationship between the impact frame 41 and the launching tube 100 can be adjusted by the adjustment device 43 so that the impact frame 41 and the launching tube 100 come into contact during the test. Preferably, the adjustment device 43 consists of two sets, including screw holes on the vertical frame 212, pads installed on the outside of the vertical frame 212, shims installed on the outside of the pads, and bolts with one end passing through the shims, pads, and screw holes and connecting to the impact frame 41. Before the test, the position of the impact frame 41 is adjusted by adjusting the length of one end of the two sets of bolts extending into the mounting groove 211, so that the impact frame 41 and the launching tube 100 are in contact and abutting.

[0036] During the test, the impact hammer 321 will act on the impact plate 42, and the force will be transmitted to the impact frame 41 through the impact plate 42. Since the impact frame 41 is in contact with the launching tube 100, the force is transmitted to the launching tube 100 through the impact frame 41. The setting of the impact plate 42 will effectively prevent the launching tube 100 from being damaged and the impact hammer 32 from being deformed during the impact.

[0037] This invention achieves different impact effects by changing the angle formed between the axis of the hammer handle 323 and the outer side of the support frame 21, as well as the weight of the counterweight 322 on the hammer head, thereby changing the force applied by the hammer head to the impact plate 42 according to the test requirements.

[0038] on the other hand: A method for simulating a drone launch impact test, based on the aforementioned drone launch impact test equipment, specifically includes the following steps: According to the test requirements, the ground fixing device 1 and the launching tube fixing device 2 are connected by different connecting mechanisms 5; according to the test requirements, the weight of the swing impact device 3 and its relative position with the protection mechanism 4 are adjusted, that is, the angle between the axis of the hammer handle 323 and the center of the impact plate 42 and the plane where the first pin 312 is located is changed. The larger the angle, the farther the distance between the swing hammer head and the center of the impact plate 42 is, and vice versa. The launch tube 100 is installed so that the inner side of the protective mechanism 4 contacts and fits against the launch tube 100; specifically, after the launch tube 100 is installed in the mounting groove 211, the impact frame 41 is controlled to abut against the launch tube 100 by the adjusting device 43. Release the limiting position of the hammer handle 323 and the rotating mounting plate 31, and the hammer handle 323 rotates around its first pin 312, applying force to the side of the impact plate 42 away from the launching tube 100. The impact plate 42 will transfer the impact force it is subjected to to the impact frame 41, and then to the launching tube 100 through the impact frame 41, thus realizing the horizontal load hammer test.

[0039] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
