Description

Technical Field

[0001] This utility model belongs to the field of health emergency equipment technology, specifically relating to a hoisting mechanism for a health emergency drone robot dog. Background Technology

[0002] In extreme scenarios triggered by natural disasters such as earthquakes and floods, power outages, communication disruptions, and road blockages often hinder rescue forces from quickly reaching disaster areas to provide medical assistance. In such situations, the ability to rapidly establish communication links between the front lines and the rear, accurately assess the damage to disaster areas and medical institutions, and facilitate efficient on-site self-rescue becomes crucial to reducing casualties. Currently, drones equipped with robotic dogs are being used to penetrate deep into disaster sites. During missions, the drone first conducts a comprehensive aerial survey, accurately locating less damaged medical institutions before smoothly landing and releasing the robotic dog. Operators remotely control the robotic dog to penetrate the building's interior, comprehensively assessing structural stability, equipment damage, and material reserves. Meanwhile, medical experts at the rear, relying on the remote communication link established by the drone, robotic dog, and satellite, collaborate with frontline personnel in real time to quickly determine whether less damaged medical institutions in the disaster area are suitable for establishing emergency rescue stations. This allows for the full activation of existing medical resources for self-rescue during the critical rescue period, significantly improving disaster relief efficiency and the survival rate of affected people.

[0003] Currently, different models of robot dogs are used. After the robot dog is installed on the drone using a single mounting bracket, the position of the robot dog cannot be adjusted. The weight of the robot dog can easily cause the drone to be unbalanced on one side, affecting the normal flight of the drone and making it difficult to control the drone. Utility Model Content

[0004] This utility model provides a hoisting mechanism for a robotic dog on a medical emergency drone, which aims to solve the problem in the prior art that the robotic dog, after being installed on the drone, can easily cause the drone to become unbalanced and affect normal flight.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a hoisting mechanism for a medical emergency drone robot dog, comprising:

[0006] A mounting bracket is used to fix the device to the drone, and the length direction of the mounting bracket is defined as the first direction.

[0007] There are two sliding blocks, which are mounted on the fixed frame and have a degree of freedom to adjust their positions along a first direction.

[0008] A connecting bracket is detachably mounted on the sliding block, and the connecting bracket is used to connect and fix it to the robot dog;

[0009] A quick-release mechanism is provided between the sliding block and the connecting frame to enable quick disassembly between the sliding block and the connecting frame.

[0010] In one possible implementation, the fixing frame includes two parallel guide rods spaced apart, the length direction of the guide rods being arranged along a first direction, the sliding block being slidably disposed between the two guide rods, and the sliding block being threadedly connected to a clamping member for abutting against the outer wall of the guide rod.

[0011] In one possible implementation, the mounting bracket further includes mounting plates fixed to both ends of the two guide rods, the mounting plates being used to fix the device to the drone.

[0012] In one possible implementation, a first fixing block is fixedly installed on the bottom of the fixing plate, and a second fixing block is detachably installed on the first fixing block. The first fixing block and the second fixing block form a fixing hole for fixing the guide rod.

[0013] In one possible implementation, the connecting bracket is inserted inside the sliding block, and the quick-release mechanism includes a pin slidably disposed on the sliding block, the pin being insertable into the connecting bracket to limit the connecting bracket inside the sliding block.

[0014] In one possible implementation, a pushing component for driving the pin to slide on the sliding block is further provided on one side of the sliding block, the pushing component comprising:

[0015] A swing arm is rotatably mounted on one side of the sliding block;

[0016] The connecting rod is hinged at one end to the swing rod and at the other end to the pin.

[0017] In one possible implementation, the middle part of the swing rod is rotatably disposed between the two sliding blocks, and both ends of the swing rod are hinged with connecting rods, with the two connecting rods respectively hinged to the corresponding pins of the two sliding blocks.

[0018] In one possible implementation, a connecting plate is fixedly connected between the two sliding blocks, and a driving component is fixedly mounted on the connecting plate. The driving end of the driving component is connected to the swing rod for driving the swing rod to swing.

[0019] In one possible implementation, the end of the connecting bracket is provided with a pin hole for installing a pin, and the end of the pin hole is provided with a chamfer to facilitate the pin sliding into the pin hole.

[0027] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] Please refer to the following: Figures 1 to 4The present invention provides a description of the hoisting mechanism for a medical emergency drone / robot dog. The hoisting mechanism includes a fixed frame 1, sliding blocks 2, a connecting frame 3, and a quick-release mechanism. The fixed frame 1 is used to fix the drone to the drone, and the length direction of the fixed frame 1 is defined as the first direction. There are two sliding blocks 2, which are mounted on the fixed frame 1, and their positions on the fixed frame 1 have a degree of freedom that can be adjusted along the first direction. The connecting frame 3 is detachably mounted on the sliding blocks 2 and is used to connect and fix the drone to the robot dog. The quick-release mechanism is located between the sliding blocks 2 and the connecting frame 3 to achieve rapid disassembly between the sliding blocks 2 and the connecting frame 3.

[0029] The medical emergency drone robot dog hoisting mechanism provided in this embodiment, compared with the prior art, features a fixed frame 1 with both ends for fixing to the bottom of the drone. Two sliding blocks 2 are installed on the fixed frame 1, spaced apart. A connecting frame 3 is detachably installed on each sliding block 2. The top of the connecting frame 3 is detachably mounted on the sliding block 2, and the bottom of the connecting frame 3 is fixedly mounted on the robot dog. In this application, when installing the robot dog onto the drone, the fixed frame 1 is first fixed to the drone. Then, the connecting frame 3 is connected to the top of the robot dog. By adjusting the position of the sliding blocks 2, the connecting frame 3 is inserted into the sliding blocks 2, thus connecting the robot dog to the drone. Simultaneously adjusting the positions of the two sliding blocks 2 brings the robot dog's center of gravity closer to the center of the drone, enabling stable flight and ensuring stability during flight.

[0030] In some embodiments, the aforementioned fixing frame 1 may be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 The fixing frame 1 includes two parallel guide rods 11 spaced apart, with the length direction of the guide rods 11 along a first direction. A sliding block 2 is slidably disposed between the two guide rods 11, and a tightening member 21 for abutting against the outer wall of the guide rod 11 is threaded onto the sliding block 2. The two guide rods 11 are spaced apart and parallel, and the same sliding block 2 is slidably disposed between the two guide rods 11. This prevents the sliding block 2 from flipping along the pitch angle and simultaneously improves the connection strength of the sliding block 2.

[0031] Specifically, in this embodiment, a guide hole is provided on the sliding block 2 to slide with the guide rod 11, and a threaded through hole is provided on the side wall of the guide hole. The clamping member 21 is a bolt, which can be used to clamp the sliding block 2 on the guide rod 11 to achieve the fixation of the sliding block 2 on the guide rod 11.

[0032] Specifically, in this embodiment, a weight-reducing hole is provided in the middle of the sliding block 2 to reduce the weight of the sliding block 2.

[0033] In some embodiments, the aforementioned fixing frame 1 may be as follows: Figure 1 , Figure 3 The structure shown. See also... Figure 1 , Figure 3 The mounting bracket 1 also includes mounting plates 12 fixed to both ends of the two guide rods 11. The mounting plates 12 are used to fix the drone. The mounting plates 12 are provided with mounting holes for fixing to the drone, and the ends of the guide rods 11 are fixedly mounted to the bottom of the mounting plates 12. The two ends of the two guide rods 11 are respectively fixedly mounted to the two mounting plates 12. The mounting plates 12 can fix the position of the two guide rods 11, allowing them to be mounted on the drone.

[0034] In some embodiments, the guide rod 11 may be adopted as follows: Figure 3 The structure shown. See also Figure 3 A first fixing block 5 is fixedly installed on the bottom of the fixing plate 12, and a second fixing block 6 is detachably installed on the first fixing block 5. The first fixing block 5 and the second fixing block 6 form a fixing hole for fixing the guide rod 11. The first fixing block 5 is fixedly installed on the bottom of the fixing plate 12 by bolts, and the second fixing block 6 is detachably installed on the side of the first fixing block 5 away from the fixing plate 12 by bolts. The opposite sides of the first fixing block 5 and the second fixing block 6 are provided with an arc-shaped structure that matches the shape of the guide rod 11. When the second fixing block 6 is fixed to the first fixing block 5 by bolts, the guide rod 11 is pressed between the first fixing block 5 and the second fixing block 6, thereby fixing the guide rod 11.

[0035] Specifically, in this embodiment, during the installation process, the first fixing block 5 is first installed onto the fixing plate 12, and then a suitable position on the drone is selected to fix the fixing plate 12 to the bottom of the drone. After the two fixing plates 12 are fixed, the guide rod 11 is then fixed between the two fixing plates 12 by the second fixing block 6.

[0036] In some embodiments, the connecting frame 3 described above may be as follows: Figure 2 , Figure 4 The structure shown. See also... Figure 2 , Figure 4 The connecting bracket 3 is inserted inside the sliding block 2, and the quick-release mechanism includes a pin 7 slidably disposed on the sliding block 2. The pin 7 can be inserted into the connecting bracket 3 to limit the connecting bracket 3 inside the sliding block 2. A mounting hole for inserting the top end of the connecting bracket 3 is provided in the middle of the sliding block 2. The mounting hole is a square hole, and the top end of the connecting bracket 3 is slidably disposed inside the mounting hole. Therefore, when the top end of the connecting bracket 3 is inserted into the mounting hole, it can prevent the connecting bracket 3 from rotating on the sliding block 2, ensuring the stability of the installation position of the connecting bracket 3.

[0037] Specifically, in this embodiment, the top of the connecting frame 3 is an arc-shaped structure that facilitates sliding into the mounting hole, and a limiting platform is provided on the connecting frame 3 to abut against the bottom surface of the sliding block 2, thereby limiting the position of the top of the connecting frame 3 inside the sliding block 2.

[0038] Specifically, in this embodiment, a pin 7 is slidably disposed between the connecting frame 3 and the sliding block 2. The pin 7 can be inserted between the connecting frame 3 and the sliding block 2 to fix the connecting frame 3 and the sliding block 2. Furthermore, the connecting frame 3 is inserted into the interior of the sliding block 2 from the bottom. When the pin 7 is pulled out from the interior of the connecting frame 3, the connecting frame 3 detaches from the sliding block 2 according to the robot dog's own weight, thereby realizing the detachment of the robot dog from the drone.

[0039] In some embodiments, the aforementioned actuating component may employ, for example... Figure 4 The structure shown. See also Figure 4 A pushing assembly for driving the pin 7 to slide on the sliding block 2 is also provided on one side of the sliding block 2. The pushing assembly includes a swing rod 41 and a connecting rod 42. The swing rod 41 is rotatably mounted on one side of the sliding block 2; one end of the connecting rod 42 is hinged to the swing rod 41, and the other end is hinged to the pin 7. The hinge axis of the swing rod 41 on one side of the sliding block 2 is parallel to the hinge axes of the swing rod 41 and the connecting rod 42, and the axes are all arranged in the vertical direction. When the swing rod 41 swings on one side of the sliding block 2, the pin 7 moves through the transmission of the connecting rod 42.

[0040] Optionally, in this embodiment, an electric push rod is also hinged to one side of the sliding block 2. The fixed end of the electric push rod is hinged to one side of the sliding block 2, and the driving end of the electric push rod is hinged to the swing rod 41. By controlling the working state of the electric push rod, the swing rod 41 is driven to swing on the sliding block 2. The working state of the electric push rod can be remotely controlled by the controller, thereby enabling the robot dog to automatically detach from the drone. The specific control method is prior art and will not be described here.

[0041] In some embodiments, the aforementioned swing arm 41 may be as follows: Figure 4 The structure shown. See also Figure 4 The swing arm 41 is rotatably positioned between two sliding blocks 2 at its center, and both ends of the swing arm 41 are hinged with connecting rods 42. The two connecting rods 42 are respectively hinged to the corresponding pins 7 of the two sliding blocks 2. When the swing arm 41 swings, it can swing synchronously through the two connecting rods 42, thereby achieving synchronous movement of the corresponding pins 7 of the two sliding blocks 2. This allows the two connecting frames 3 to simultaneously detach from the sliding blocks 2, completing the separation of the robot dog from the drone.

[0042] In some embodiments, the sliding block 2 described above can be as follows: Figure 4 The structure shown. See also Figure 4 A connecting plate 8 is fixedly connected between the two sliding blocks 2. A driving component 43 is fixedly installed on the connecting plate 8. The driving end of the driving component 43 is connected to the swing rod 41 to drive the swing rod 41 to swing. The two ends of the connecting plate 8 are fixedly installed on the bottom of the two sliding blocks 2 by bolts. This not only fixes the two sliding blocks 2 together, but also provides installation space for the driving component 43 and the swing rod 41. The driving component 43, which is a motor, is fixedly installed at the bottom of the connecting plate 8. The middle part of the swing rod 41 is fixedly installed on the driving end of the driving component 43, and the swing rod 41 can be driven to swing through the driving component 43. This allows control of the corresponding pins 7 of the two sliding blocks 2, enabling the robot dog to automatically disengage.

[0043] Preferably, in this embodiment, the working state of the drive component 43 can be remotely controlled by the controller, thereby enabling the robot dog to automatically detach from the drone. The specific control method is existing technology and will not be described further here.

[0044] In some embodiments, the connecting frame 3 described above may be as follows: Figure 4 The structure shown. See also Figure 4 The end of the connecting frame 3 is provided with a pin hole for mounting the pin 7, and the end of the pin hole is provided with a chamfer to facilitate the pin 7 sliding into the pin hole. The pin 7 slides in the pin hole, and a through hole of the same size as the pin hole is provided on the sliding block 2. The pin 7 is always located inside the through hole on the sliding block 2. The end of the pin hole on the connecting frame 3 is provided with an inclined chamfer, which can guide the pin 7 to slide into the pin hole, making it easy to install the robot dog on the drone.

[0045] Preferably, in this embodiment, the end of the pin 7 near the connecting bracket 3 is a spherical structure, which makes it easier for the pin 7 to slide into the pin hole through the guide of the end of the pin 7 and the chamfer.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
