Description

Technical Field

[0001] This invention relates to the technical field of optoelectronic pods, and more specifically, to a linkage device for the deployment and retraction of an optoelectronic pod and the opening and closing of a door for flight equipment. Background Technology

[0002] Electro-optical pods are widely used in unmanned aerial vehicles (UAVs) for reconnaissance, identification, tracking, and surveillance of targets on land, sea, or in the air. Currently, UAV electro-optical pods are mainly fixedly installed in the belly of the fuselage. This causes aerodynamic drag during flight, affecting operational efficiency. Furthermore, the pods protrude from the fuselage, making them susceptible to damage from impacts during takeoff and landing. Therefore, a deployment and retrieval mechanism is needed to retract the pod into the pod for standby and extend it out during operation. This mechanism requires a hatch.

[0003] Existing technologies offer numerous solutions for the deployment and retraction of electro-optical pods and independent door opening and closing mechanisms. However, few mention mechanisms that coordinate the deployment and retraction of the pod with door opening and closing. For the two independent functional requirements of deployment and retraction and door opening and closing, existing technologies can only use two sets of equipment. Each set is equipped with a motion mechanism, motors and drive devices, and control units, which occupies space on the pod, increases weight, and raises costs. Furthermore, the coordinated control of these two sets of equipment faces challenges, potentially leading to incoordination and conflicts, or even equipment damage. To avoid such situations, more sensors are needed for detection, further increasing costs. A coordinated mechanism for the deployment and retraction of the electro-optical pod and door opening and closing significantly improves pod protection, simplifies equipment structure, controls weight, and reduces costs. Summary of the Invention

[0004] To address the problem that the existing door opening / closing and retraction mechanisms are not tightly coordinated, which can easily lead to improper timing of door opening or closing, this invention provides a linkage device for the retraction and retraction of an optoelectronic pod and the opening / closing of a door for flight equipment.

The lead screw nut is movably sleeved on the lead screw, and the lead screw nut is detachably fixedly connected to the transmission body.

At the same time, the hooks of the snap-fit ​​unit are arranged on the transmission body, and in conjunction with the stops arranged on the sliding body of the transmission unit, the force of the first elastic element is used to synchronously drive the sliding body to move on the first guide rail.

After the photoelectric pod is completed and retracted into the cabin, the hatch is closed synchronously. This achieves the coordinated movement of the two mechanisms, simplifies the number of devices, and reduces costs. Attached Figure Description

[0029] Significant progress has been made in the technology of existing UAV electro-optical pods, but there are still many shortcomings in the linkage mechanism for opening and closing the pod door. Current technologies mostly focus on the design and optimization of single functional modules, lacking systematic research on the coordinated operation of the pod's deployment and retrieval mechanisms and the door opening and closing mechanisms. Currently, the deployment and retrieval mechanisms and door opening and closing mechanisms of the electro-optical pods are designed independently, requiring two separate motion mechanisms, drive control units, and limit structures. These two sets of equipment occupy considerable space within the pod, are difficult to install and arrange, and increase structural weight, failing to meet the design requirements of small and lightweight UAVs. Furthermore, the two sets of control equipment increase costs. Regarding coordination, the existing door opening and closing mechanisms often do not work closely enough with the deployment and retrieval mechanisms, easily leading to improper timing of door opening or closing, affecting the normal operation of the electro-optical pods.

[0030] To address the aforementioned shortcomings, this invention integrates the two structural functions of the photoelectric pod 1 (deployment and retrieval) and the hatch (opening and closing) into a coordinated design, thereby achieving coordinated movement of the photoelectric pod 1 and the hatch (opening and closing) functions, simplifying the number of devices and reducing costs.

[0031] like Figures 1 to 5 As shown, the present invention discloses a linkage device for the deployment and retrieval of an optoelectronic pod 1 and the opening and closing of a cabin door for a flight device.

[0032] The flight equipment includes a cabin 11 with an opening at its bottom. A first door 2 and a second door are provided at the opening. In this application, the first door 2 and the second door move in opposite directions when they are open, and move in the same direction when they are retracted.

[0033] like Figure 1 As shown, the retraction and hatch opening / closing linkage device includes: a support 6, which is detachably fixed inside the cabin 11; a transmission unit, which includes a first guide rail 12, a slider 13, a first linkage assembly, and a second linkage assembly; the first guide rail 12 is detachably fixed to the support 6, and the slider 13 is slidably disposed on the first guide rail 12; one end of the first linkage assembly is movably connected to the slider 13 to form a first engagement, and the other end of the first linkage assembly is detachably connected to the first hatch 2; one end of the second linkage assembly is movably connected to the slider 13 to form a second engagement, and the other end of the second linkage assembly is detachably connected to the second hatch; and a drive unit, which includes... The system includes a transmission body 17, a drive assembly, and a mounting bracket 3. The drive assembly is detachably fixed to a support 6, the transmission body 17 is movably connected to the drive assembly, and the mounting bracket 3 is detachably fixed to the transmission body 17. A photoelectric pod 1 is fixedly mounted on the mounting bracket 3. The system also includes a snap-fit ​​unit, which includes a stop block 20, a hook 19, and a first elastic element 21. The hook 19 is detachably fixed to the transmission body 17. One end of the stop block 20 is hinged to a sliding body 13, and the two opposite ends of the first elastic element 21 abut against the sliding body 13 and the stop block 20, respectively. An abutment portion is formed on the end of the stop block 20 away from the side where the first elastic element 21 is located, and the abutment portion is movably fitted with the hook 19.

[0034] In this embodiment, the drive assembly in the drive unit drives the transmission body 17 to move, thereby realizing the retraction and extension of the photoelectric pod 1. At the same time, the hook 19 of the snap-fit ​​unit is arranged on the transmission body 17 and cooperates with the stop 20 arranged on the sliding body 13 of the transmission unit. The force of the first elastic element 21 is used to synchronously drive the sliding body 13 to move on the first guide rail 12. Then, the opening and closing states of the first hatch 2 and the second hatch are controlled by driving the first linkage assembly and the second linkage assembly. The two motion mechanisms of retraction and extension of the photoelectric pod and opening and closing of the hatch are combined. Before the photoelectric pod 1 is released outside the cabin for work, the hatch is opened. After the photoelectric pod 1 is retracted into the cabin, the hatch is closed synchronously. The coordinated movement of the two mechanisms is achieved, which simplifies the number of devices and reduces costs.

[0035] Specifically, the end of the stop block 20 away from the sliding body 13 has an abutment portion, which extends toward the end of the sliding body 13. The end of the stop block 20 away from the first elastic member 21 has a guide surface formed between the abutment portion and the abutment portion, and the guide surface and the abutment surface of the abutment portion are smoothly connected.

[0036] Specifically, the drive assembly includes a motor 9, a lead screw nut 18, and a lead screw 5. The lead screw 5 is rotatably connected to the opposite ends of the support 6 along the extension direction of the first guide rail 12. The motor 9 is fixedly connected to the support 6, and the output shaft of the motor 9 is connected to the lead screw 5 for transmission. The lead screw nut 18 is movably sleeved on the lead screw 5, and the lead screw nut 18 is detachably fixedly connected to the transmission body 17.

[0037] Specifically, the mounting bracket 3 is also provided with a limiting component 10, which is movably matched with the limiting structure 7 of the support 6. The limiting component 10 is used to limit the circumferential rotation of the transmission body 17 around the lead screw 5.

[0038] Specifically, a limiting block is provided at one end of the first guide rail 12 near the bottom of the cabin 11, and a buffer is arranged on the limiting block. The other end of the first guide rail 12 extends toward the top of the support 6, and a guide is also provided at the top of the support 6. The guide is arranged to movably cooperate with the contact part of the stop block 20.

[0039] Specifically, the first linkage assembly includes a first elastic link 15, a first rocker arm, and a second elastic member 4. One end of the first elastic link 15 is hinged to the sliding body 13 to form a first joint, and the other end of the first elastic link 15 is hinged to one end of the first rocker arm to form a third joint. The first rocker arm is hinged to the support 6 to form a fourth joint 16, and the other end of the first rocker arm is detachably connected to the first hatch 2. One end of the second elastic member 4 is fixed to the support 6, and the other end of the second elastic member 4 is hinged to the first rocker arm to form a fifth joint. The fourth joint 16 is located between the third joint and the fifth joint, and the second elastic member 4 is in a compressed state.

[0040] Specifically, the second linkage assembly includes a second elastic link, a second rocker arm, and a third elastic member; one end of the second elastic link is hinged to the sliding body 13 to form a second joint, the other end of the second elastic link is hinged to one end of the second rocker arm to form a sixth joint, the second rocker arm is hinged to the support 6 to form a seventh joint, and the other end of the second rocker arm is detachably connected to the second hatch; one end of the third elastic member is fixed to the support 6, the other end of the third elastic member is hinged to the second rocker arm to form an eighth joint, the seventh joint is located between the sixth joint and the eighth joint, and the third elastic member is in a compressed state.

[0041] Specifically, when the first hatch 2 and the second hatch are closed, the first joint, the third joint, the fourth joint 16 and the fifth joint are not on the same straight line; the second joint, the sixth joint, the seventh joint and the eighth joint are not on the same straight line.

[0042] In this embodiment, the support 6 is fixedly installed inside the cabin 11, and the limiting structure 7 is fixedly installed on the support 6. A limiting member 10 is movably fitted on the limiting structure 7, and the limiting member 10 moves up and down on the limiting structure 7. The photoelectric pod 1 is installed on the limiting member 10 via the mounting bracket 3 and the transmission body 17. In this application, the limiting structure 7 can be a guide rail, and the limiting member 10 can be a slider. The transmission body 17 is connected to the lead screw nut 18. The two ends of the lead screw 5 are supported and installed on the support 6 by angular contact bearings. The output end of the reducer is meshed with the transmission gear on the lead screw 5. After the motor 9 rotates, it drives the lead screw to rotate through the reducer, which is converted into linear motion of the lead screw nut 18. The lead screw nut 18 drives the photoelectric pod 1 and forces the slider to slide on the guide rail, realizing the extension and retraction movement of the photoelectric pod 1. The motor 9 integrates a brake, which can receive control commands to lock the rotor, ensuring that the photoelectric pod 1 remains stable during operation or standby. The motor 9 is controlled by a drive controller.

[0043] Specifically, the first guide rail 12 is fixedly installed on the cabin 11, the sliding body 13 slides along the first guide rail 12, and the first hatch 2 is installed on the support 6 via the first rocker arm, allowing it to rotate around the fourth joint 16. The second elastic member 4 is stretched to connect the first hatch 2 to the support 6. In its natural state, the first hatch 2 is in an open state, such as... Figure 2 As shown. The first rocker arm and the sliding body 13 are connected by the first elastic connecting rod 15. Controlling the position of the sliding body 13 can control the opening and closing of the first hatch 2, as shown. Figure 3 As shown. In this application, the fourth joint 16 can be a pivot, and the second elastic member 4 can be a spring.

[0044] Specifically, the second hatch is mounted on the support 6 via a second rocker arm, which can rotate around the seventh joint. The third elastic element connects the second hatch to the support 6, and in its natural state, the second hatch is in the open position. The second rocker arm is connected to the sliding body 13 via a second elastic link, and controlling the position of the sliding body 13 controls the opening and closing of the second hatch. In this application, the seventh joint can be a pivot, and the third elastic element can be a spring.

[0045] Specifically, hook 19 is fixedly installed on transmission body 17 and moves linearly with lead screw nut 18. Stop 20 is hinged to sliding body 13 and can rotate around an axis. A first elastic element 21 is provided between stop 20 and sliding body 13. Under the pre-elastic force of the first elastic element 21, stop 20 remains as follows. Figure 4 and Figure 5 As shown, when hook 19 is above stop 20, hook 19 moves downward and abuts against the guide surface. By continuing to drive hook 19 downward, it pushes stop 20 to compress the first elastic element 21, allowing it to smoothly pass stop 20 and continue downward. When hook 19 is below stop 20, hook 19 is blocked by the abutment of stop 20 when moving upward. This forces stop 20 to move slider 13 upward as well, dragging the first hatch 2 and the second hatch to close under the action of the first and second linkage assemblies. When hook 19 forces stop 20 to move to the top support 6, the abutment of stop 20 contacts the guide, compressing the first elastic element 21 under the contact force, forcing stop 20 to separate from hook 19. Stop 20 and the connected slider 13 move downward under the action of the second and third elastic elements until they touch the limit block. To avoid strong impact, a buffer is provided between slider 13 and limit block. In this application, the first elastic element 21 can be a compression spring.

[0046] In this embodiment, the process from standby to working state and back to standby state of the photoelectric pod 1 is as follows: In the standby state, the first and second doors are closed, the photoelectric pod 1 is inside the pod, the hook 19 is above the stop block 20, the controller controls the motor 9 to rotate, causing the lead screw 5 to move upward, dragging the stop block 20 upward to contact the top support 6. This process utilizes the elasticity of the elastic connecting rod to extend it. After continuous contact, the stop block 20 compresses the first elastic element 21, causing the stop block 20 to separate from the hook 19. Under the combined action of the second elastic element 4 connected to the first door 2 and the third elastic element connected to the second door, the pod is stretched and dragged. The stop block 20 and the slider 13 move downward along the first guide rail 12 to the limit block, the first hatch 2 and the second hatch open, and then the controller controls the motor 9 to rotate so that the lead screw 5 drives the photoelectric pod 1 to move downward, passing the stop block 20 to the lowest working point, and reaching the working state; after the photoelectric pod 1 finishes working, the controller controls the motor 9 to rotate so that the lead screw 5 drives the photoelectric pod 1 to move upward. When it moves to the stop block 20, it pushes the stop block 20 and the slider 13 connected to it to move upward, dragging the hatch to close, and reaching the standby state. In this process, the photoelectric pod 1 first moves upward into the cabin and then closes the cabin, so no collision will occur.

[0047] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
