Description

Technical Field

[0001] The present application relates to the field of unmanned aerial vehicle payload equipment, and in particular to an unmanned aerial vehicle airborne optoelectronic pod. Background Art

[0002] The optoelectronic pod onboard a drone is an important component of modern drone systems and is widely used in military reconnaissance, environmental monitoring, fire source detection and other fields. With the rapid development of drone technology, the demand for optoelectronic pods is also increasing. The optoelectronic pod can achieve high-precision target recognition and tracking by carrying various optical devices, such as cameras and infrared imagers. However, in actual applications, the performance and even life of the optoelectronic pod will be damaged during the flight of the drone. For example, the drone may suddenly change speed in an emergency, causing the fuselage to vibrate easily. The vibration will not only affect the acquisition of the image, but also easily affect the service life of the internal equipment of the optoelectronic pod. In addition, after the acquisition of the image is affected, the risk of drone flight will also increase.

[0003] In order to reduce these adverse effects, the commonly used solutions currently include using vibration reduction devices to absorb and buffer vibration energy. A common vibration reduction method is to set vibration reduction parts such as springs or rubber pads between the drone and the optoelectronic pod to absorb vibration energy through the deformation of the vibration reduction parts. However, this method can usually only achieve vibration reduction in a single direction and cannot provide a good vibration reduction protection effect. Summary of the invention

[0004] In order to solve the problem that the performance or life of the optoelectronic pod is easily damaged due to vibration or other unexpected conditions, the present application provides an optoelectronic pod onboard a drone.

[0005] The present application provides an unmanned aerial vehicle airborne optoelectronic pod that adopts the following technical solution: An unmanned aerial vehicle airborne optoelectronic pod comprises a vibration reduction component and a pod body; The vibration reduction assembly comprises a first mounting member, a second mounting member, a third mounting member and a plurality of vibration reduction units, wherein the first mounting member comprises a first connecting portion and a first sleeve portion, and one end of the first sleeve portion is connected to the first connecting portion; The second mounting member comprises a second connecting portion and a second sleeve portion, the second connecting portion is located inside the first sleeve portion, one end of the second sleeve portion is connected to the second connecting portion, and the other end of the second sleeve portion passes through the first sleeve portion; The third mounting member is disposed at an end of the first sleeve portion away from the first connecting portion and is used to limit the position of the second connecting portion; The vibration reduction unit includes a first elastic member, a second elastic member, a slider and an abutment rod, the first elastic member is arranged between the second connecting part and the third mounting member, the second elastic member, the slider and the abutment rod are all located between the first connecting part and the second connecting part, the slider is slidably connected to the first connecting part, one end of the second elastic member is connected to the slider, and the other end is connected to the first sleeve part, and the opposite ends of the abutment rod are respectively hinged to the slider and the second connecting part.

[0006] By adopting the above technical solution, the UAV airborne optoelectronic pod can effectively reduce the vibration transmitted to the interior of the pod during flight and improve the stability of the captured images. Specifically: The first elastic member is arranged between the second connecting part and the third mounting member, and can absorb most of the vibration force in the vertical direction, thereby reducing the influence of the external environment on the equipment in the cabin.

[0007] The design of the second elastic member, the slider and the abutment rod can effectively buffer the vibration in the horizontal direction, further improving the stability and reliability of the system. In addition, no matter whether the vibration direction of the second mounting member is in the vertical direction or the horizontal direction, the second elastic member can effectively absorb the vibration energy.

[0008] The two ends of the abutment rod are hinged to the slider and the second connection part respectively. This design can realize the effective transmission and dispersion of force, avoid excessive stress on a single component, and extend the service life.

[0009] In summary, the UAV-mounted optoelectronic pod provided by the present invention not only has excellent vibration reduction performance, but also has high reliability and durability, and is particularly suitable for the needs of performing tasks in high-altitude operations or complex environments.

[0010] Preferably, the third mounting member is threadedly connected to the first sleeve portion.

[0011] By adopting the above technical solution, the third mounting member is threadedly connected to the first sleeve portion so that the position of the third mounting member can be changed, and then the pre-compression amount of the first elastic member and the second elastic member can be adjusted to ensure that the first elastic member and the second elastic member can both have a good vibration reduction effect. In addition, since the third mounting member can also limit the second connecting portion, the threaded connection between the third mounting member and the first sleeve portion also makes it easy to disassemble and assemble the first mounting member, the second mounting member, the third mounting member and the vibration reduction unit, which is convenient for replacing components and improves the stability and reliability of the entire vibration reduction assembly.

[0012] Preferably, the second mounting member further comprises a lifting plate, the lifting plate is slidably connected to the second sleeve portion, the lifting plate abuts against the third mounting member, and the first elastic member is disposed between the lifting plate and the second connecting portion.

[0013] By adopting the above technical solution, the first elastic member does not directly contact the third mounting member, so that when the third mounting member rotates relative to the first sleeve portion, the first elastic member will not be laterally offset along with the third mounting member.

[0014] Preferably, the vibration reduction unit further includes a third elastic member, and two opposite sides of the third elastic member are respectively in contact with the first connecting portion and the second connecting portion.

[0017] By adopting the above technical solutions, the vibration reduction performance of the UAV airborne optoelectronic pod is significantly improved. Specifically: The fourth elastic member is arranged between the third mounting member and the second connecting portion, which further enhances the vibration reduction effect and effectively absorbs vibration energy.

[0018] One of the first elastic member and the fourth elastic member is selected as a spring, and the other is an airbag, so that the vibration reduction system can show excellent vibration reduction characteristics under vibrations of different frequencies, thereby improving the adaptability and reliability of the system. In addition, the airbag can have a vibration reduction effect in multiple directions, and can also prevent the spring from being overly compressed under the gravity of the cabin.

[0019] Preferably, a limiting groove is provided on the inner side wall of the first sleeve portion, and a limiting protrusion is provided on the side wall of the second connecting portion, and the limiting protrusion penetrates into the limiting groove.

[0020] By adopting the above technical solution, the limiting protrusion penetrates into the limiting groove, so that the limiting groove can limit the second connection part in the circumferential direction. And because the second elastic member can exert a force in the horizontal direction on the second connection part, the limiting protrusion does not need to contact the limiting groove, so as to avoid the vibration caused by the contact being transmitted to the second connection part.

[0021] Preferably, the UAV airborne optoelectronic pod also includes a storage cabin and a storage drive assembly, wherein the storage drive assembly is connected to the first mounting member and is used to drive the vibration reduction assembly and the cabin body to enter or escape from the storage cabin.

[0022] By adopting the above technical solution, the UAV-mounted optoelectronic pod can realize the automatic storage and release of the vibration reduction components and the pod during flight, thus avoiding damage to the pod in sudden or severe situations.

[0023] Preferably, the storage cabin has a cabin door, and the storage drive assembly is connected to the cabin door and is used to drive the cabin door to switch between the first state and the second state; In the first state, the cabin door is closed, and the vibration reduction assembly and the cabin body are located in the storage cabin; In the second state, the door is open, and the vibration reduction assembly and the cabin body are located outside the storage cabin.

[0024] By adopting the above technical solution, the storage cabin of the UAV-mounted optoelectronic pod has a door, and the storage drive assembly is connected to the door, so that the door can be switched between the first state and the second state. In the first state, the door is closed, and the vibration reduction assembly and the cabin are safely protected in the storage cabin, effectively preventing the external environment from affecting the equipment; in the second state, the door is opened, and the vibration reduction assembly and the cabin can be quickly deployed to the working position, improving the convenience of operation and work efficiency.

[0025] Preferably, the cabin door comprises a first door panel, a second door panel, a first rack and a second rack, wherein the first rack is arranged on the first door panel, and the second rack is arranged on the second door panel; The storage drive assembly includes a motor, a lead screw and a gear. The lead screw is rotatably connected to the inner wall of the storage compartment, the motor is connected to the lead screw, the first connecting portion is connected to the nut of the lead screw, the gear is sleeved on the lead screw, the first rack and the second rack are both engaged with the gear, and when the gear rotates, the first rack and the second rack approach or move away from each other.

[0026] By adopting the above technical solution, the automatic opening and closing function of the hatch of the UAV airborne optoelectronic pod can be realized. Specifically: By setting the first rack and the second rack to be connected to the first door panel and the second door panel respectively, and making the two racks mesh with the gear, when the motor drives the lead screw to rotate, the opening and closing of the first door panel and the second door panel can be controlled. This design not only improves the convenience and reliability of the hatch operation, but also can link the opening and closing of the hatch with the storage and ejection of the cabin body, ensuring the safety of the optoelectronic pod.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up multiple groups of vibration reduction units, each vibration reduction unit includes a first elastic member, a second elastic member, a slider and an abutment rod, which can effectively absorb and buffer vibration energy of different frequencies, and the second mounting member does not need to be in direct contact with the first mounting member, further reducing the impact of vibration on the cabin body from the UAV, and improving the stability and reliability of the optoelectronic pod under complex working conditions; 2. The threaded connection design between the third mounting member and the first sleeve portion is not only convenient for assembly and disassembly, but also makes the pre-compression amount of the first elastic member and the second elastic member adjustable, further improving the vibration reduction effect; 3.

[0035] The following is combined with Figures 1 to 6 This application is described in further detail.

[0036] like Figures 1 to 3 As shown, an embodiment of the present application discloses an optoelectronic pod onboard a drone, comprising: a vibration reduction component 1, a gimbal 2 and a pod body 3.

[0037] The photoelectric pod on the drone is directly or indirectly connected to the drone via its vibration reduction assembly 1. The vibration reduction assembly and the cabin 3 are connected via a universal mount 2, so that the cabin 3 can change its orientation relative to the drone.

[0038] Specifically, Figure 1 As shown, the gimbal 2 includes an azimuth stator frame 21, an azimuth arm 22 and a pitch arm 23. The azimuth stator frame 21 is connected to the vibration reduction assembly 1 and the azimuth arm 22 respectively, and one end of the azimuth arm 22 away from the azimuth stator frame 21 is connected to the pitch arm 23. The cabin 3 includes a cabin shell and working equipment located in the cabin shell. The cabin shell includes a front cover 31, a rear cover 32 and a side cover 33, wherein the side cover 33 is connected to the pitch arm 23.

[0039] A first brushless motor is provided inside the azimuth stator frame 21, and the first brushless motor is used to drive the azimuth arm 22 to rotate. A second brushless motor is provided on the azimuth arm 22, and the second brushless motor is used to drive the pitch arm 23 to rotate. A third brushless motor is provided on the side cover 33, and the third brushless motor is used to drive the front cover 31, the rear cover 32 and the working equipment in the cabin shell to rotate. By providing the first brushless motor, the second brushless motor and the third brushless motor, the front cover 31, the rear cover 32 and the working equipment in the cabin shell can realize azimuth rotation, roll rotation and pitch rotation.

[0040] The working equipment in the cabin shell may include optical detection components, speed and position measurement components, video tracking and recording boards, computer boards, etc.

[0041] The optical detection assembly may include a visible light television and an infrared thermal imager. When the optoelectronic pod on the drone is flying with the drone, the visible light television and the infrared thermal imager can obtain images to perform reconnaissance tasks. The images can be transmitted to the ground station for observation by ground staff. Ground operators can control the television and thermal image conversion field of view to identify the target and track the target. For example, by controlling the drive assembly (the first brushless motor, the second brushless motor and the third brushless motor) to change the direction of the optical detection assembly, the target can be better searched and tracked.

[0042] The speed position measurement component may include a three-axis gyroscope and a magnetic encoder, wherein the three-axis gyroscope is used to monitor the angular velocity of the optical detection component when the optical detection component is turned. The magnetic encoder is used to achieve precise positioning of the optical detection component when the optical detection component is turned.

[0043] The video tracking and recording board mainly performs image preprocessing, video tracking and output. It receives two channels of high-definition digital video from visible light television and infrared thermal imaging channels, overlays graphics and characters on the video images, gives tracking deviations, and finally outputs the video. The video can store the original video on the hard disk inside the board through the recording function, and can be reviewed retrospectively.

[0044] The computer board mainly completes the summary processing and output of information, such as receiving external control instructions to complete the steering or function control of the optical detection component.

[0045] like Figure 1 to Figure 2 As shown, the vibration reduction assembly 1 includes a first mounting member 11, a second mounting member 12, a third mounting member 13 and a plurality of vibration reduction units 14. The first mounting member 11 includes a first connecting portion 111 and a first sleeve portion 112. One end of the first sleeve portion 112 is connected to the first connecting portion 111. The second mounting member 12 includes a second connecting portion 121 and a second sleeve portion 122. The second connecting portion 121 is located on the inner side of the first sleeve portion 112. One end of the second sleeve portion 122 is connected to the second connecting portion 121, and the other end passes through the first sleeve portion 112. The first connecting portion 111 and the second connecting portion 121 can both be circular flat plates, such as circular flanges, and the first connecting portion 111 is used to connect to the drone. The first sleeve portion 112 and the second sleeve portion 122 can both be cylindrical barrels. The azimuth stator frame 21 is connected to the second sleeve portion 122.

[0046] The third mounting member 13 is disposed at one end of the first sleeve portion 112 away from the first connecting portion 111 and is used to limit the second connecting portion 121 to prevent the second connecting portion 121 from escaping from the first sleeve portion 112 .

[0047] Multiple groups of vibration reduction units 14 can be arranged at intervals along the circumferential direction. The vibration reduction unit 14 includes a first elastic member 141, a second elastic member 142, a third elastic member 143, a slider 144 and an abutment rod 145. The first elastic member 141 is vertically arranged between the second connecting portion 121 and the third mounting member 13, so as to reduce vibration and support the second mounting member 12 in the vertical direction.

[0048] The second elastic member 142, the third elastic member 143, the slider 144 and the abutting rod 145 are all located between the first connecting portion 111 and the second connecting portion 121. The third elastic member 143 is vertically arranged, and its two opposite sides are respectively abutted against the first connecting portion 111 and the second connecting portion 121. The third elastic member 143 can also play a vibration reduction role in the vertical direction.

[0049] The first connection part 111 is provided with a slide groove, and the slider 144 is located in the slide groove and is slidably connected with the slide groove on the first connection part 111. The second elastic member 142 is arranged horizontally, and one end of the second elastic member 142 is connected to the slider 144 (for example, abutting), and the other end is connected to the first sleeve part 112, and the opposite ends of the abutment rod 145 are respectively hinged to the slider 144 and the second connection part 121. When the second connection part 121 vibrates in the vertical direction, the first elastic member 141 and the third elastic member 143 can play a role in vibration reduction and energy absorption in the vertical direction, and the second elastic member 142 can simultaneously apply a force to the second connection part 121 in the vertical direction and the horizontal direction, thereby preventing the second elastic member 142 from vibrating.

[0050] For example, Figure 1 As shown, when the second connection part 121 moves upward, the second elastic member 142 will be compressed, and the reaction force of the second elastic member 142 includes a downward vertical component and a horizontal component pointing to the middle of the first sleeve part 112. The vertical component can prevent the second connection part 121 from moving upward, and the horizontal component can keep the second connection part 121 in the middle of the inner side of the first sleeve part 112 to prevent the second connection part 121 from contacting the first sleeve part 112. When the second connection part 121 vibrates in the horizontal direction, the second elastic member 142 can also be compressed. The second elastic member 142 can not only apply a horizontal force to prevent the second connection part 121 from vibrating and absorb the vibration energy in the horizontal direction, but also apply a vertical force to the second connection part 121, converting part of the vibration energy in the horizontal direction into the vertical direction and being absorbed by the first elastic member 141, the second elastic member 142 and the third elastic member 143.

[0051] Through the joint action of multiple groups of vibration reduction units 14, no matter the second connecting part 121 vibrates in the vertical direction or the horizontal direction, the first elastic member 141, the second elastic member 142 and the third elastic member 143 can simultaneously play a role in vibration reduction and energy absorption, thereby reducing the impact on the second mounting member 12 and the cabin body 3.

[0052] It should be noted that the vertical direction mentioned above is a direction parallel to the axis of the first sleeve portion 112 , and the horizontal direction is a direction perpendicular to the axis of the first sleeve portion 112 .

[0053] Furthermore, a limiting groove 1121 is provided on the inner side wall of the first sleeve portion 112, and a limiting protrusion is provided on the side wall of the second connecting portion 121, and the limiting protrusion penetrates into the limiting groove 1121, so that the limiting groove 1121 can play a circumferential limiting role on the second connecting portion 121. In addition, due to the presence of the second elastic member 142, the limiting protrusion does not need to contact the inner wall of the limiting groove 1121, so as to avoid the vibration from the first mounting member 11 to the second mounting member 12. Of course, a rubber vibration-damping pad can be provided in the limiting groove 1121, and even if the limiting protrusion collides with the inner wall of the limiting groove 1121, the rubber vibration-damping pad can still reduce vibration.

[0054] Furthermore, if Figures 1 to 3 As shown, the vibration reduction unit 14 also includes a fourth elastic member 146, which is disposed between the third mounting member 13 and the second connecting portion 121. Of the first elastic member 141 and the fourth elastic member 146, one is a spring and the other is an airbag. For example, the first elastic member 141 can be a spring and the fourth elastic member 146 can be an airbag. The first elastic member 141 can play a good role in vibration reduction and energy absorption in the vertical direction, while the fourth elastic member 146 can not only play a role in vibration reduction and energy absorption in all directions, but also assist in supporting the second connecting portion 121, thereby preventing the first elastic member 141 from being over-compressed due to the excessive weight of the second mounting member 12 and the cabin 3.

[0055] The second elastic member 142 and the third elastic member 143 may also be springs.

[0056] Furthermore, along the axial direction of the first sleeve portion 112, the position of the third mounting member 13 is adjustable, so that by adjusting the position of the third mounting member 13, the pre-compression amount of the first elastic member 141, the second elastic member 142, the third elastic member 143 and the fourth elastic member 146 can be changed, so that the vibration reduction unit 14 has a better vibration reduction effect.

[0057] For example, the third mounting member 13 is threadedly connected to the first sleeve portion 112. By rotating the third mounting member 13, not only the position of the third mounting member 13 can be changed, but also the third mounting member 13 can be separated from the first sleeve portion 112, thereby facilitating disassembly and replacement of components of the vibration damping assembly 1.

[0058] In addition, the second mounting member 12 further includes a lifting plate 123, the lifting plate 123 is slidably connected to the second sleeve portion 122, the lifting plate 123 is in contact with the third mounting member 13, and the first elastic member 141 is disposed between the lifting plate 123 and the second connecting portion 121. By providing the lifting plate 123 to separate the third mounting member 13 from the first elastic member 141, it is possible to prevent the first elastic member 141 from being offset when the third mounting member 13 rotates.

[0059] like Figures 4 to 5As shown, the UAV airborne optoelectronic pod also includes a storage cabin 200 and a storage drive assembly 4. The storage cabin 200 can be formed on a mounting component (a component for connecting the first connecting portion 111 to the UAV, which can be regarded as a part of the UAV airborne optoelectronic pod) or the bottom of the UAV body.

[0060] The storage drive assembly 4 is connected to the first mounting member 11 and is used to drive the vibration reduction assembly 1, the universal mount 2 and the cabin body 3 to enter or escape from the storage cabin 200. When the optoelectronic pod is not working or encounters an emergency, by storing the cabin body 3 and other components in the storage cabin 200, it helps to reduce wind resistance and the probability of damage to the optoelectronic pod.

[0061] In addition, a door 201 is provided at the bottom of the storage cabin 200, and the storage drive assembly 4 is connected to the door 201 and can drive the door 201 to switch between the first state and the second state.

[0062] Specifically, Figure 5 to Figure 6 As shown, the hatch 201 includes a first door panel 2011, a second door panel 2012, a first rack 2013 and a second rack 2014. The first rack 2013 is arranged on the first door panel 2011, and the second rack 2014 is arranged on the second door panel 2012; like Figure 4 As shown, the storage drive assembly 4 includes a motor 41, a lead screw 42 and a gear 43, the lead screw 42 is rotatably connected to the inner wall of the storage compartment 200, the motor 41 is connected to the lead screw 42, the gear 43 is sleeved on the lead screw 42, the first connecting portion 111 is connected to the nut of the lead screw 42, and the first rack 2013 and the second rack 2014 are both meshed with the gear 43. When the gear 43 rotates, the first rack 2013 and the second rack 2014 are moved closer to or farther away from each other.

[0063] For example, when the motor 41 drives the screw 42 to rotate, so that the gear 43 drives the first rack 2013 and the second rack 2014 to approach each other, the vibration reduction assembly 1, the universal joint 2 and the cabin body 3 can move into the storage cabin 200 under the action of the screw 42. When the cabin body 3 and other components completely enter the storage cabin 200, the first door panel 2011 and the second door panel 2012 completely close the storage cabin 200, and the cabin door 201 is closed. At this time, the cabin door 201 is in the first state.

[0064] On the contrary, when the motor 41 drives the screw 42 to rotate, so that the gear 43 drives the first rack 2013 and the second rack 2014 to move away from each other, the hatch 201 gradually opens, and the vibration reduction assembly 1, the universal mount 2 and the cabin body 3 can move out of the storage cabin 200. When the cabin body 3 and other components are completely out of the storage cabin 200, the hatch 201 is fully opened, and the hatch 201 is in the second state.

[0065] Through the above arrangement, the motor 41 can simultaneously drive the cabin door 201, the cabin body 3 and other components to move, thereby saving energy and achieving better coordination between the cabin door 201, the cabin body 3 and other components.
