Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) take-off and landing platform technology, and in particular to an automatic take-off and landing platform for emergency communication vehicles and its usage method. Background Technology

[0002] Existing vehicle-mounted drone lifting platforms typically employ multiple independent drive mechanisms (such as multiple motors driving multiple lead screws) to coordinate the platform's lifting and lowering. This approach has a significant drawback in practical deployment: because the response characteristics, mechanical wear, or control errors of multiple drive units are difficult to maintain absolute consistency, it easily leads to asynchrony during lifting and lowering, causing platform tilting and level inaccuracies. This problem is particularly pronounced under long-term use or harsh operating conditions.

[0003] For high-precision automated take-off and landing of drones, the levelness of the platform is crucial. The platform tilt caused by insufficient synchronization not only increases the risk of collisions or rollovers during drone take-off and landing, affecting operational safety, but also limits the stable deployment of communication payloads, ultimately hindering the realization of the rapid and reliable deployment capability of emergency communication systems. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic take-off and landing platform for emergency communication vehicles and a method for using it, which solves the technical problems of asynchronous lifting, easy tilting, and difficulty in maintaining levelness caused by the use of multiple independent drive mechanisms in existing vehicle-mounted drone lifting platforms.

[0005] To achieve the above objectives, the present invention provides an automatic take-off and landing platform for an emergency communication vehicle-mounted unmanned aerial vehicle (UAV), comprising an emergency vehicle and a carriage, the carriage being mounted on the emergency vehicle, and further comprising a lifting assembly; the lifting assembly comprises a lifting platform, a first lead screw, a second lead screw, a first lifting seat, a second lifting seat, and a driving component, the first lead screw and the second lead screw being fixedly connected to the carriage and located inside the carriage, the first lifting seat being slidably connected to the first lead screw, the second lifting seat being slidably connected to the second lead screw, and the lifting platform being fixedly connected to the first lifting seat and the second lifting seat; the first lifting seat comprises a seat body and a lead screw nut, the lead screw nut being threadedly connected to the first lead screw and sleeved on the first lead screw, the seat body being rotatably connected to the lead screw nut and sleeved on the lead screw nut, the lifting platform being fixedly connected to the seat body, and the driving component being mounted on the lifting platform and used to drive the lead screw nut to rotate.

[0006] The driving component includes a geared motor, a first transmission rod, a drive gear, and a driven gear. The geared motor is connected to the lifting platform and located on one side of the lifting platform. The first transmission rod is mounted on the geared motor and connected to the output end of the geared motor, and is rotatably connected to the base. The driven gear is fixedly connected to the lead screw nut and is sleeved on the lead screw nut. The drive gear is fixedly connected to the first transmission rod and meshes with the driven gear.

[0007] The emergency communication vehicle-mounted drone automatic take-off and landing platform also includes a maintenance door, which is rotatably connected to the vehicle body and located on one side of the vehicle body.

[0008] The lifting assembly also includes a lighting fixture, which is fixedly connected to the lifting platform and located on one side of the lifting platform.

[0009] The lifting assembly also includes a camera, which is fixedly connected to the lifting platform and located on the side of the lifting platform closer to the lighting lamp.

[0010] The lifting assembly further includes a sealing component, which includes a fixed plate, a sliding cover, and an electric push rod. The fixed plate is fixedly connected to the carriage and located on one side of the carriage. The electric push rod is connected to the fixed plate and located on one side of the fixed plate. The sliding cover is disposed on the electric push rod and connected to the output end of the electric push rod.

[0011] The sealing component further includes a guide rod and a guide seat. The guide rod is fixedly connected to the carriage and located on the side of the carriage near the sliding cover. The guide seat is slidably connected to the guide rod and fixedly connected to the sliding cover, and is sleeved on the guide rod.

[0012] On the other hand, the present invention also includes a method for using an automatic take-off and landing platform for an emergency communication vehicle-mounted drone, comprising the following steps: Controlling the electric actuator to move the sliding cover smoothly along the guide rod, fully opening the opening on the top of the carriage; The reduction motor is started, and the lifting platform carrying the drone is driven to rise synchronously and smoothly through the drive component, and reaches the predetermined working position on the top of the carriage through the opening; during this process, the lights can be turned on as needed, and the take-off and landing status can be monitored through the camera; Control the drone to complete the tethered connection on the platform and take off automatically to perform aerial operations; After the operation is completed, the drone is controlled to return to home and land on the lifting platform. Then, the lifting platform is controlled to descend synchronously into the carriage, where it is supported by the buffer pad.

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] First embodiment: Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of an emergency communication vehicle-mounted drone automatic take-off and landing platform. Figure 2 This is a structural diagram of the lifting assembly. Figure 3 This is a schematic diagram of the installation structure of the lead screw and nut.

[0026] This invention provides an automatic take-off and landing platform for vehicle-mounted unmanned aerial vehicles (UAVs) used in emergency communication, including an emergency vehicle 101, a vehicle body 102, and a lifting assembly 103. The lifting assembly 103 includes a lifting platform 104, a first lead screw 105, a second lead screw 106, a first lifting seat 107, a second lifting seat 108, and a driving component 109. The first lifting seat 107 includes a seat body 110 and a lead screw nut 111. The driving component 109 includes a reduction motor 112, a first transmission rod 113, a drive gear 114, and a driven gear 115. The driving component 109 drives the lead screw nut 111 inside the first lifting seat 107 and the second lifting seat 108 to rotate, thereby causing the first lifting seat 107 and the second lifting seat 108 to rise and fall on the first lead screw 105 and the second lead screw 106, achieving the purpose of driving the lifting platform 104 to rise and fall. It is understood that the aforementioned solution can be used in vehicle-mounted mobile emergency communication, monitoring, and support scenarios where there are stringent requirements for platform lifting synchronization, stability, and deployment speed.

[0027] In this specific embodiment, the first lead screw 105 and the second lead screw 106 are both fixedly connected to the carriage 102 and located inside the carriage 102. The first lifting seat 107 is slidably connected to the first lead screw 105, and the second lifting seat 108 is slidably connected to the second lead screw 106. The lifting platform 104 is fixedly connected to the first lifting seat 107 and the second lifting seat 108. The lead screw nut 111 is threadedly connected to the first lead screw 105 and sleeved on the first lead screw 105. The seat body 110 is rotatably connected to the lead screw nut 111 and sleeved on the lead screw nut 111. The lifting platform 104 is fixedly connected to the seat body 110. The driving component 109 is disposed on the lifting platform 104 and is used to drive the lead screw nut 111 to rotate.

[0028] Two of each of the first lead screw 105 and the second lead screw 106 are provided, and they are respectively located on the left and right sides of the carriage 102. Two of each of the first lifting seats 107 and the second lifting seats 108 are also provided. Two first lifting seats 107 are provided on two first lead screws 105, and two second lifting seats 108 are provided on two second lead screws 106. The structure of the first lifting seat 107 and the structure of the second lifting seat 108 are the same. The structure and working principle of the second lifting seat 108 will not be described in detail here.

[0029] The top of the carriage 102 is provided with an opening, through which the drone on the lifting platform 104 can rise to the outside of the carriage 102 or descend to be stored inside the carriage 102, realizing the safe storage and rapid take-off and landing of the drone within the carriage 102. When the lifting platform 104 descends, the drone can be housed inside the carriage 102 and is well protected. When operation is required, the drive component 109 drives each of the lead screw nuts 111 to rotate synchronously, driving the lifting platform 104 to rise smoothly, lifting the drone and sending it through the opening to the predetermined working position on the top of the carriage 102 for take-off. This invention integrates storage, lifting, and take-off and landing functions into one unit, effectively utilizing vehicle space and significantly improving the convenience, automation, and environmental adaptability of emergency communication vehicle deployment.

[0030] The geared motor 112 is connected to the lifting platform 104 and located on one side of the lifting platform 104; the first transmission rod 113 is mounted on the geared motor 112 and connected to the output end of the geared motor 112, and is rotatably connected to the base 110; the driven gear 115 is fixedly connected to the lead screw nut 111 and is sleeved on the lead screw nut 111; the drive gear 114 is fixedly connected to the first transmission rod 113 and meshes with the driven gear 115; the geared motor 112 has two output ends, and the first transmission rod 113 has two parts, each connected to one of the two output ends of the geared motor 112; the drive gear 114 has two parts. The first transmission rod 113 is connected to the two first transmission rods 113 respectively. The operation of the reduction motor 112 drives the two first transmission rods 113 to rotate. The first transmission rod 113 drives the drive gear 114 mounted on it to rotate. The drive gear 114 drives the driven gear 115 to rotate. The driven gear 115 drives the lead screw nut 111 inside the seat 110 to rotate, thereby causing the lead screw nut 111 to rotate relative to the fixed first lead screw 105. Since the axial position of the first lead screw 105 is fixed by the carriage 102, the rotational motion of the lead screw nut 111 will be converted into its own linear lifting motion along the axis of the first lead screw 105, thereby driving the seat 110 to lift.

[0031] Secondly, the driving component 109 further includes two second transmission rods 117, which are connected to the first lifting seat 107 and the second lifting seat 108 respectively. Each end of the second transmission rod 117 is provided with a transmission gear 116. The two transmission gears 116 mesh with the corresponding driven gears 115 on the first lifting seat 107 and the second lifting seat 108 respectively, thereby synchronously transmitting the power output by the reduction motor 112 to the two second lifting seats 108. When the reduction motor 112 drives the driven gear 115 inside the first lifting seat 107 to rotate via the first transmission rod 113, the driven gear 115 drives the meshing transmission gear 116 to rotate, thereby driving the second transmission rod 117 to rotate. The rotation of the second transmission rod 117, in turn, drives the driven gear 115 inside the second lifting seat 108 to rotate synchronously via the transmission gear 116 at the other end, achieving the purpose of synchronously raising and lowering the two first lifting seats 107 and the two second lifting seats 108.

[0032] Second embodiment: Based on the first embodiment, please refer to Figures 4 to 7 , Figure 4 This is a schematic diagram of the installation structure of the access door in the second embodiment. Figure 5This is a schematic diagram of the camera mounting structure according to the second embodiment. Figure 6 This is the second embodiment. Figure 5 Enlarged view of point A, Figure 7 This is a schematic diagram of the installation structure of the electric actuator in the second embodiment. The emergency communication vehicle-mounted drone automatic take-off and landing platform in this embodiment also includes an inspection door 201. The lifting assembly 103 also includes a lighting lamp 202, a camera 203, a sealing component 204, a support seat 210, and a buffer pad 211. The sealing component 204 includes a fixing plate 205, a sliding cover 206, an electric actuator 207, a guide rod 208, a guide seat 209, and a sealing pad 212.

[0033] In this specific embodiment, the inspection door 201 is rotatably connected to the carriage 102 and is located on one side of the carriage 102; the inspection door 201 facilitates daily inspection and maintenance of the interior of the carriage 102 and the lifting assembly 103.

[0034] The lighting lamp 202 is fixedly connected to the lifting platform 104 and is located on one side of the lifting platform 104.

[0035] Secondly, the camera 203 is fixedly connected to the lifting platform 104 and is located on the side of the lifting platform 104 near the lighting lamp 202.

[0036] Both the lighting 202 and the camera 203 are fixedly installed on the lifting platform 104 and face upwards. When the lifting platform 104 is working at night or in an environment with insufficient light, the lighting 202 can provide sufficient lighting for the take-off and landing of the drone and the area around the platform. The camera 203 can collect visual information such as the drone's attitude and tether cable connection status on the platform in real time and transmit the images to the in-vehicle control terminal to assist operators in monitoring or as input for automatic recognition algorithms, thereby improving the system's visualization and intelligence level.

[0037] Meanwhile, the sealing component 204 includes a fixing plate 205, a sliding cover 206, and an electric actuator 207. The fixing plate 205 is fixedly connected to the carriage 102 and is located on one side of the carriage 102. The electric actuator 207 is connected to the fixing plate 205 and is located on one side of the fixing plate 205. The sliding cover 206 is disposed on the electric actuator 207 and is connected to the output end of the electric actuator 207.

[0038] In addition, the guide rod 208 is fixedly connected to the carriage 102 and is located on the side of the carriage 102 near the sliding cover 206; the guide seat 209 is slidably connected to the guide rod 208 and fixedly connected to the sliding cover 206, and is sleeved on the guide rod 208.

[0039] The sealing component 204 is used to seal the opening at the top of the carriage 102 after the lifting platform 104 is lowered back into the carriage 102, so as to protect the internal equipment from the intrusion of external environment such as rain and dust; the electric push rod 207 drives the sliding cover 206 to open or close, thereby opening or closing the opening; the guide rod 208 guides the movement of the guide seat 209, thereby guiding the movement of the sliding cover 206 and improving the stability of the sliding cover 206 when it moves.

[0040] Then, the sealing member 204 further includes a sealing gasket 212, which is fixedly connected to the fixing plate 205 and located on the side of the fixing plate 205 near the sliding cover 206; when the sliding cover 206 is closed, the sealing gasket 212 can seal the gap between the sliding cover 206 and the fixing plate 205, thereby improving the sealing effect of the sliding cover 206.

[0041] Finally, the support base 210 is fixedly connected to the carriage 102 and located inside the carriage 102; the buffer pad 211 is fixedly connected to the support base 210 and located on the side of the support base 210 close to the lifting platform 104; when the lifting platform 104 completes its descent, its lower surface will land on the buffer pad 211; the support base 210 provides stable mechanical support for the platform, preventing components such as the lead screw of the lifting mechanism from bearing static load on the platform for a long time; the buffer pad 211 can absorb the slight impact when the platform lands, reduce noise and vibration, and play a certain role in shock absorption and protection.

[0042] When using the emergency communication vehicle-mounted unmanned aerial vehicle (UAV) automatic take-off and landing platform of the present invention, the emergency vehicle 101 is first driven to the work area and brought to a stop. The electric actuator 207 is then activated to drive the sliding cover 206 to move along the guide rod 208 to fully open the opening at the top of the vehicle compartment 102. Next, the reduction motor 112 is started. The reduction motor 112 drives the two first transmission rods 113 to rotate synchronously through its two output ends, which in turn drives the drive gear 114 to rotate. The drive gear 114 drives the driven gear 115 in the first lifting seat 107 to rotate, thereby driving the lead screw nut 111 to rotate. Simultaneously, the rotation of the driven gear 115 is transmitted to the second transmission rod 117 through the meshing transmission gear 116, driving the driven gear 115 in the second lifting seat 108 to rotate synchronously. The four lead screw nuts 111 located at the four corners of the platform rotate in perfect unison under rigid mechanical linkage, smoothly and horizontally lifting the lifting platform 104 and the drone on it through the opening to the predetermined working position on the top of the carriage 102. The lighting 202 can provide illumination when the ambient light is insufficient, and the camera 203 can monitor the take-off and landing status of the drone in real time. The drone then performs automatic take-off and tethering operations. After the mission is completed, the drone automatically lands on the platform, the reduction motor 112 reverses, and drives the platform to descend synchronously and smoothly into the carriage 102, where the lower surface of the platform is supported by the buffer pad 211. Finally, the electric push rod 207 is controlled to close the sliding cover 206, and the sealing gasket 212 ensures that the opening is sealed, completing the entire recovery and protection process. Routine maintenance can be performed by opening the inspection door 201.

[0043] On the other hand, please see Figure 8 The present invention also includes a method for using an automatic take-off and landing platform for an emergency communication vehicle-mounted drone, comprising the following steps: S1: Control the electric push rod to drive the sliding cover to slide smoothly along the guide rod, and fully open the opening on the top of the carriage; S2: Start the reduction motor, drive the lifting platform to lift the drone synchronously and smoothly through the drive component, and reach the predetermined working position on the top of the carriage through the opening; during this process, the lights can be turned on as needed, and the take-off and landing status can be monitored through the camera; S3: Control the drone to complete the tethered connection on the platform and take off automatically to perform aerial operation tasks; S4: After the operation is completed, control the drone to return and land on the lifting platform, and then control the lifting platform to descend synchronously into the carriage, where it is supported by the buffer pad; S5: Control the electric push rod to close the sliding cover to achieve an opening seal, and routine system maintenance can be performed through the inspection door.
