Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a rigid cabin body for UAV emergency rescue. Background Technology
[0002] In the field of emergency medical care, timely and effective treatment is the key line of defense for protecting patients' lives and health. The traditional emergency medical system relies heavily on on-site response by ground emergency vehicles and medical personnel. However, in scenarios such as the normalization of urban traffic congestion and significant geographical barriers in remote areas, it is often difficult to overcome spatial limitations and reach patients within the "golden treatment time." This not only causes patients to miss the best treatment window but also significantly increases the risk factor for life-saving treatment.
[0003] With technological innovation, drones are becoming a game-changer in the field of emergency medical care. Their speed advantage and immunity to ground transportation allow them to quickly reach areas traditionally neglected by emergency services, buying precious time for critically ill patients. However, the practical application of drone-based emergency medical care technology still faces two major technical bottlenecks:
[0004] First, there are reliability defects in the connection system: existing drones and patient transport cabins generally use tow ropes or hooks for connection. These flexible connection structures are not only not durable enough, but also lack a visual connection status monitoring mechanism, which makes it impossible for the operator to monitor the connection stability in real time. In actual rescue, the cabin sliding or even separating often occurs, which seriously threatens the safety of patient transport. Secondly, the above-mentioned connection methods are mostly distributed on the side where the drone and the cabin are in contact, so the stability of the connection cannot be observed intuitively, which makes it impossible to detect risks in the first place.
[0005] Secondly, the cabin is prone to collision with the ground: In the rescue operation process, the cabin is attached to the ground before being grabbed, while the drone only carries out take-off and landing operations through simple connection. This means that when the drone lands, the cabin will inevitably touch the ground before the fuselage, forming a hard collision impact similar to "tower crane unloading". This mechanical impact may cause secondary injury to the patient inside the cabin, which is technically conflicting with the core objective of emergency rescue operations. Therefore, we propose a rigid cabin for drone emergency rescue. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this utility model provides a rigid cabin for drone-based emergency medical services, solving the technical problems of poor connection stability and the risk of secondary injury to patients during use of existing drone-based emergency medical cabins.
[0008] (II) Technical Solution
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] A rigid cabin for drone-based emergency rescue, the cabin being connectable to the main body of the drone, the cabin comprising:
[0011] A docking assembly connected to the main body of the drone;
[0012] The cabin frame can be connected to the docking components on the main body of the drone, and the interior is used to place patients awaiting emergency treatment.
[0013] The docking assembly includes two opposing support frames, which are driven by a drive component on the docking assembly to open and close. When the support frames move toward the cabin frame, they can be fitted onto the end of the cabin frame.
[0014] Preferably, the driving component includes a lead screw with two sets of threads in opposite directions, located at both ends of the lead screw. The two support frames are respectively connected to one set of threads. When the lead screw rotates, it can drive the two support frames to open and close.
[0015] The distance between the two support frames when fully open is greater than the length of the cabin frame, and the ends of the cabin frame correspond to the holes on the support frames.
[0016] Preferably, the driving component further includes a driven worm gear connected to the end of the lead screw, and the driven worm gear meshes with a driving worm inside the docking assembly. One end of the driving worm is connected to an extension rod, and the extension rod is connected to a handwheel on the outside of the docking assembly.
[0017] When the handwheel rotates, it can drive the lead screw to rotate synchronously.
[0018] Preferably, the bottom of the cabin frame is connected to two opposing lifting plates, and the lifting plates are equipped with casters to allow the emergency cabin to slide and rub against the ground.
[0019] The lifting plate has a ramp facing the end of the cabin frame, and the inner wall of the support frame is equipped with pulleys opposite to the lifting plate. When the support frame moves in the direction of the cabin frame, the pulleys on the support frame slide along the ramp on the lifting plate, raising the horizontal height of the cabin frame.
[0020] Preferably, a connecting rod is installed on each side of the docking assembly, and the end of the connecting rod corresponds to the guide groove on the surface of the support frame. When the support frame and the end of the connecting rod are in contact, the joint of the end of the connecting rod is located at the opening of the guide groove.
[0021] The guide groove extends downward along the outer wall of the support frame, and the connector can slide along the guide groove to the bottom of the support frame under the action of gravity.
[0022] Preferably, a traction motor is installed inside the docking assembly, and a traction rope is connected to the output shaft of the traction motor. The other end of the traction rope is connected to a connecting rod. When the traction motor winds up the traction rope, it can pull the connecting rod to move towards the location of the docking assembly.
[0023] Preferably, the frame includes a first aid cabin, and the first aid cabin is hinged to the outside with a cover. Both ends of the first aid cabin are provided with instrument compartments for storing instruments.
[0024] Preferably, a clamping member is installed on the top of the docking assembly and is connected to a bracket on the main body of the drone via the clamping member. The clamping member includes a base and a compression cap that are screwed together, and the base is connected to the docking assembly.
[0025] When the bracket is connected to the docking assembly, the base and the compression cap are located on both sides of the rod-shaped structure on the bracket.
[0026] (III) Beneficial Effects
[0027] First, the two support frames are driven by a drive mechanism to open and close. When the cabin is placed between the two support frames, the drive mechanism can move the support frames towards the cabin, so that they fit over the end of the cabin until the support frames come into contact with the casters at the bottom of the cabin, thus completing the fitting of the cabin. Then, the position between the two support frames is fixed by a connecting rod to restrict the sliding of the support frames and ensure that the support frames will not move during transportation. This design effectively solves the technical problem of poor connection stability when using existing UAV emergency rescue cabins, and realizes the visible connection of the cabin. At the same time, the support frames and the connecting rod form a stable "rectangular frame" that can stably clamp the cabin, improving the safety and stability of cabin transportation.
[0028] Secondly, a ramped lifting plate is used as the load-bearing structure for the casters, and pulleys are installed on the inner wall of the support frame. When the support frame moves towards the casters, the cabin can be lifted to a certain height along the ramp of the lifting plate under the compression of the support frame, thus separating the cabin from the ground. This design effectively solves the technical problem that existing drone emergency cabins are prone to causing secondary injuries to patients, realizes the separation of the cabin from the ground, avoids the impact force of the drone landing directly acting on the cabin, and thus improves the safety of patients.

[0050] This application provides a rigid cabin for drone-based emergency medical services, solving the technical problems of poor connection stability and the risk of secondary injury to patients in existing drone-based emergency medical cabins. In existing drone-based emergency medical cabins, a drive mechanism moves two support frames to open and close. When the cabin is placed between the two support frames, the drive mechanism moves the support frames towards the cabin, thus securing them to the ends of the cabin until they contact the casters at the bottom of the cabin. A connecting rod then fixes the position of the two support frames, restricting their sliding and ensuring movement during cabin transport. This also enables visibility of the cabin. The design incorporates a modular connection, forming a stable rectangular frame through the connection of the support frame and connecting rods. This securely holds the cabin in place, enhancing the safety and stability of its transport. Furthermore, the use of a ramped lifting plate as the load-bearing structure for the casters, along with pulleys installed on the inner wall of the support frame, allows the cabin to be lifted and moved higher when the support frame compresses it, thus separating the cabin from the ground. This effectively solves the technical problem of existing drone-based emergency rescue cabins potentially causing secondary injuries to patients during use. It also achieves cabin separation from the ground, preventing the impact of the drone landing from directly affecting the cabin and improving patient safety.
[0051] Example: The technical solution in this application example solves the technical problem that existing drone emergency rescue cabins have poor connection stability and are prone to causing secondary harm to patients during use. The overall idea is as follows:
[0052] To address the problems existing in the prior art, this utility model provides a rigid cabin for drone-based emergency medical services. This cabin can be connected to the drone body 1 and is primarily used to house patients. The drone then transports the cabin containing the patient to the hospital, thus enabling patient transport via drone and resolving the traffic congestion issues associated with existing ambulances. To this end, we have developed a cabin that can be connected and detached from the drone, and is applicable to various large drones. It mainly consists of three parts: first, the drone body 1, which is a large drone to accommodate the patient's weight; second, the cabin frame 3, which, to reduce patient discomfort, uses a reclining cabin as the patient transport housing; and third, the docking component 2 for connecting the drone body 1 and the cabin frame 3. To be compatible with different types and models of drone bodies 1, a replaceable docking component 2 is used instead of modifying the drone itself, thus avoiding incompatibility with other drones. The specific structure is as follows:
[0053] The main body of the drone 1 is a large drone with a support 4. The reason for using a drone with a support 4 is to facilitate the subsequent connection with the docking component 2. Therefore, the support 4 of the drone can be used as the connection structure of the docking component 2.
[0054] In order to connect the docking assembly 2 to the bracket 4 of the drone body 1, a clamping component 5 (such as a pipe clamp) is installed on the top of the docking assembly 2. The clamping component 5 is used to connect the docking assembly 2 to the bracket 4 on the drone body 1. Figure 13 As shown, the clamping component 5 consists of two parts: an arc-shaped base 51 and an arc-shaped compression cap 52. These two parts are combined to form a complete circular sleeve. The base 51 and the compression cap 52 can be connected together by bolts. When the bracket 4 is connected to the docking assembly 2, the rod-shaped structure on the bracket 4 is aligned with the groove on the top of the base 51. After this, the compression cap 52 is placed on the other side of the rod-shaped structure, aligning with the base 51 (the screw holes on the base 51 and the screw holes on the compression cap 52 correspond vertically). Then, the base 51 and the compression cap 52 are connected together by bolts. Figure 13 As shown, at this time, the docking component 2 is fixed to the bottom of the bracket 4, thereby completing the connection between the docking component 2 and the drone body 1.
[0055] Another important structural element is the cabin frame 3, which mainly comprises a rectangular emergency cabin 31. Its interior has a storage cavity for patient placement. To reduce the difficulty of patient transport, the stretcher board 33 inside the cabin frame 3 can be removed (each of the four corners of the stretcher board 33 has a handle for easy lifting by staff). The patient is then placed flat on the stretcher board 33 and lifted into the emergency cabin 31 by staff. The upper cover 32 is then closed. To prevent the patient from feeling confined, a transparent observation panel is installed on the cover 32, corresponding to the position of the patient's head on the stretcher board 33. Figure 3 As shown; in order to facilitate ensuring the patient's physical condition during transportation, an instrument compartment 34 is opened at each end of the emergency cabin 31, which can be used to store instruments, such as oxygen cylinders.
[0056] Secondly, the cabin frame 3 is also equipped with a visual camera to facilitate timely observation of the patient's condition inside the cabin; an emergency alarm button, which can be pressed to remind the drone operator to perform an emergency landing operation, etc.
[0057] The focus of this application is on the connection method between the UAV and the cabin frame 3, thereby ensuring the stability of the connection between the UAV body 1 and the cabin frame 3 while improving the safety of the cabin frame 3. The specific improvement scheme is as follows;
[0058] Firstly, to address the stability issue during transport of the drone carrier frame 3, it's essential to understand the root causes of this instability. An investigation of existing drone mounting structures revealed that a major reason for this problem is the inability to prevent relative swaying between the drone and the carrier frame 3. Traditional drone connection structures often employ tow ropes or hooks, which, while providing a connection, cannot guarantee that the carrier frame 3 will not sway during transport. This swaying not only affects the patient's mental state but also, with continued shaking, may lead to loosening or even separation.
[0059] To solve the above problems, we use two opposing support frames 22 as the gripping structure for the UAV to grasp the cabin frame 3. The two support frames 22 are driven by a drive device (drive component 23) to open and close, like a "gripper". When the two support frames 22 approach each other, they clamp the cabin frame 3 located between the support frames 22. However, the support frames 22 stop moving when they come into contact with the casters 36 at the bottom of the cabin frame 3. In this way, the movement range of the cabin frame 3 is restricted by the mutual compression between the casters 36 and the support frames 22. When the cabin frame 3 wants to move, the casters 36 are installed on it, and the movement of the cabin frame 3 will pull the casters 36. However, since the casters 36 are restricted between the support frames 22, the movement range of the cabin frame 3 is restricted.
[0060] This application uses a manually controlled drive unit 23 as an example. In addition to the drive structure given in this application, other structures and devices that can achieve the same function can also be used, and are not limited to the following structures indicated in this application.
[0061] The driving component 23 mainly includes a lead screw 231 (with a bearing housing 232 fitted at each of its two ends and the middle position, and the bearing housing 232 being connected to the outer wall of the lead screw 231 through bearings, such as...) Figure 6 and Figure 7 As shown, the bearing seats 232 are all installed in the embedded grooves on the back of the support seats 21. They have two sets of threads with opposite helical directions, located at both ends of the lead screw 231. Each of the two support frames 22 is connected to one of these sets of threads. This allows the two support frames 22 to open and close when the lead screw 231 rotates. This is because the two sets of threads on the lead screw 231 have opposite helical directions, and when the lead screw 231 rotates, the support frames 22 do not rotate synchronously with it. Instead, they move along the length of the lead screw 231 under the action of the threads. Therefore, the two support frames 22 can open and close under the action of the two threads with opposite helical directions. To provide sufficient space for the cabin frame 3, the distance between the two support frames 22 when fully open must be greater than the length of the cabin frame 3. Figure 9 and Figure 10 As shown, the end of the cabin frame 3 corresponds to the hole on the support frame 22. Thus, when the support frame 22 moves in the direction of the cabin frame 3, the cabin frame 3 passes through the hole on the support frame 22, and the support frame 22 fits onto the end of the cabin frame 3. Figure 11 As shown, the support frame 22 stops when it encounters the caster wheel 36.
[0062] To facilitate manual rotation of the lead screw 231 and prevent reverse rotation under force, a worm gear anti-locking function is employed. A driven worm gear 233 is connected to the end of the lead screw 231, and the driven worm gear 233 meshes with the drive worm 234 inside the docking assembly 2. One end of the drive worm 234 is connected to a handwheel on the outside of the docking assembly 2. Thus, rotating the handwheel 237 causes the drive worm 234 connected to the handwheel 237 to rotate synchronously. Because the drive worm 234 and the driven worm gear 233 mesh... The screw 231 is engaged with the driven worm gear 233, so when the worm gear 234 rotates, it can drive the driven worm wheel 233 to rotate. Since the lead screw 231 is connected to the driven worm wheel 233 and the support frame 22 is threadedly connected to the lead screw 231, the support frame 22 can be moved when the handwheel 237 rotates. This allows the support frame 22 to be manually started, in the same way as the rocker arm used for raising and lowering a hospital bed. Similarly, a motor with a self-locking function can be used to drive the lead screw 231 to rotate, thereby achieving automatic control.
[0063] By installing a hollow extension rod 235 at one end of the drive worm gear 234, and inserting one end of the handwheel 237 into the interior of the extension rod 235, as shown... Figure 7 As shown, this allows the handwheel 237 to slide back and forth along the extension rod 235, but prevents it from rotating relative to the extension rod 235. A limiting groove is provided on the outer side of the support base 21 near the handwheel 237. After the support frame 22 rotates to its position, the handwheel is pressed into the limiting groove. Figure 12 As shown. This locks the handwheel 237 to prevent it from shaking. In addition, when the support frame 22 is subjected to a reverse force, the force cannot be transmitted to the handwheel through the lead screw 231 (the limiting function of the worm gear).
[0064] Since one end of the two support frames 22 is connected to the lead screw and the other end is suspended, they are prone to sliding under external forces. This also affects the stability of the connection between the UAV body 1 and the cabin frame 3. Therefore, we installed a connecting rod 24 (the length of which is equal to the distance between the two sets of universal wheels 36) on each side of the support base 21, and the end of the connecting rod 24 corresponds to the guide groove 26 on the surface of the support frame 22. Figure 11 As shown, when the support frame 22 and the end of the connecting rod 24 are attached, the butt joint 25 at the end of the connecting rod 24 is located at the opening of the guide groove 26. This allows the connecting rod 24 to slide into the guide groove under its own weight. Figure 12 As shown, it slides along the guide groove to the bottom of the support frame 22. Thus, under the restriction of the connecting rod 24, the two support frames 22 cannot move freely, thereby locking them in place, forming a shape as shown. Figure 8 and Figure 12 The rectangular frame shown allows for position locking between the cabin frame 3 and the drone body 1.
[0065] Furthermore, when a reset is required, the traction rope 28 can be wound up by the traction motor 27 installed inside the docking assembly 2. Since the other end of the traction rope 28 is connected to the connecting rod 24, when the traction motor 27 (which is a motor with a self-locking function, such as a self-locking motor) rotates, the connecting rod 24 can be pulled to move towards the location of the docking assembly 2, thereby causing the connector 25 at the end of the connecting rod 24 to move out of the guide groove, thus completing the unlocking of the support frame 22.
[0066] During use, it was found that because the cabin frame 3 is attached to the ground before grabbing, the cabin will inevitably touch the ground before the fuselage when the drone lands, forming a hard impact similar to "tower crane unloading". This mechanical impact may cause secondary injury to the patient inside the cabin, creating a technical conflict with the core objective of emergency rescue operations. To solve this problem, two opposing lifting plates 35 are first connected to the bottom of the cabin frame 3, and then casters are installed on the lifting plates 35. In this way, the emergency cabin 31 can slide and rub against the ground through the casters, reducing friction. Secondly, a ramp is provided at the end of the lifting plate 35 facing the cabin frame 3. When the support frame 22 moves along the ramp, since the bottom position of the support frame 22 remains unchanged, the cabin frame 3 is lifted upward under the action of the ramp, thus separating from the ground. In order to reduce the friction 35 between the support frame 22 and the lifting plate 35, pulleys 6 opposite to the lifting plate 35 are installed on the inner wall of the support frame 22. In this way, when the support frame 22 moves in the direction of the cabin frame 3, the pulleys 6 on the support frame 22 slide along the ramp on the lifting plate 35, raising the horizontal height of the cabin frame 3 and reducing the difficulty of lifting.
[0067] In the specific implementation process, the main body 1 of the UAV carrying the docking assembly 2 is controlled to fly directly above the cabin frame 3, and the length direction of the cabin frame 3 is aligned with the positions of the two support frames 22 on the docking assembly 2, such as... Figure 9 As shown, after completion, control the drone body 1 to descend, causing the cabin frame 3 to fall between the two support frames 22, with the end of the cabin frame 3 corresponding to the hole on the support frame 22, as shown. Figure 10 As shown, after completion, the handwheel 237 on the outside of the support base 21 is turned. Since the handwheel 237 is connected to the drive worm 234 inside the support base 21, and the drive worm 234 meshes with the driven worm wheel 233, and the driven worm wheel 233 is coaxial with the lead screw 231, the handwheel 237 can drive the lead screw 237 to rotate when it rotates. Since the two support frames 22 are respectively connected to the two threads on the lead screw 231, and the helical directions of the two threads are opposite, the lead screw 231 can also drive the two support frames 22 to move towards the center when it rotates, and the end of the cabin frame 3 is inserted into the hole of the support frame 22.
[0068] Meanwhile, since a ramped lifting plate 35 is connected to the bottom of the cabin frame 3, when the support frame 22 moves along the ramp, the bottom position of the support frame 22 remains unchanged. Therefore, when the support frame 22 moves in the direction of the cabin frame 3, the pulleys 6 on the support frame 22 slide along the ramp on the lifting plate 35, raising the horizontal height of the cabin frame 3, reducing the difficulty of lifting, and allowing the cabin frame 3 to separate from the ground. Similarly, when the UAV body 1 lands, because the cabin frame 3 is raised, it will not contact the ground before the UAV. Figure 11As shown, the connection stops when the support frame 22 is in contact with the caster 36 at the bottom of the cabin frame 3, and the butt joint 25 at the end of the connecting rod 24 is located at the opening of the guide groove 26, so that the subsequent connecting rod 24 can slide into the guide groove when subjected to its own weight.
[0069] After completing the above steps, the traction motor 27 inside the control support 21 rotates in the reverse direction, releasing the traction rope 28 wound on its output shaft. At this time, the connecting rod 24 at the other end of the traction rope 28 slides along the guide groove to the bottom of the support frame 22 under its own gravity. Thus, under the restriction of the connecting rod 24, the two support frames 22 cannot move freely, thereby locking them in place, forming a... Figure 8 and Figure 12 The rectangular frame shown allows for position locking between the cabin frame 3 and the drone body 1.
[0070] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
