Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a UAV take-off and landing auxiliary device. Background Technology

[0002] In the civilian sector, multi-rotor drones have expanded from traditional aerial surveying and mapping to diversified fields such as agricultural plant protection, power line inspection, mountain rescue, and logistics delivery, becoming a key tool for improving operational efficiency and reducing labor costs. However, accident statistics show that more than 60% of civilian drone equipment damage or operational interruption accidents occur during the two critical stages of takeoff and landing. The stability of the takeoff and landing process directly determines the operational safety and overall efficiency of drones, becoming a core bottleneck restricting the further release of their civilian value.

[0003] However, existing drone take-off and landing assistance devices have the following drawbacks:

[0004] (1) Traditional integrated take-off and landing platforms are difficult to transport in complex road sections such as mountains and farmland, and the assembly is cumbersome and delays operations;

[0005] (2) Traditional take-off and landing devices are difficult to provide horizontal stability in complex terrain with uneven or sloping terrain, which makes it easy for UAVs to tip over or slip during take-off and landing.

[0006] Therefore, this utility model provides a drone take-off and landing auxiliary device. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The problem solved by this utility model is to provide a highly practical drone take-off and landing auxiliary device, which solves the problems mentioned in the background art of difficulty in transportation in complex road sections such as mountains and farmland and difficulty in providing horizontal stability support.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution: a drone take-off and landing auxiliary device, including a platform, splicing platforms are provided around the platform, a connecting component is provided between two splicing platforms, and a threaded groove is provided at the bottom of each splicing platform, with a support component provided inside the threaded groove;

[0011] The connecting assembly includes connecting blocks disposed on opposite sides of two splicing platforms. Each connecting block has protrusions on both sides, and each of the two splicing platforms has grooves on opposite sides that mate with the protrusions. The connecting block has an internal cavity, and a movable plate is movably connected to the inner wall of the cavity. A spring is connected between one side of the movable plate and the inner wall of the cavity. Trapezoidal blocks are installed at the top and bottom of the other side of the movable plate. The inner walls of the two grooves have slots that mate with the trapezoidal blocks. A pressing rod is installed at the center of the other side of the movable plate.

[0012] The support assembly includes a mounting sleeve threaded to the inner wall of a threaded groove. A telescopic rod is movably connected to the inner wall of the mounting sleeve. A threaded hole is opened at the bottom of the surface of the mounting sleeve. A threaded rod is threaded to the inner wall of the threaded hole. A connecting plate is installed at one end of the threaded rod. A positioning block is fixedly connected to one side of the connecting plate. A plurality of positioning grooves that are adapted to the positioning block are opened on the surface of the telescopic rod. A support foot is connected to the bottom of the telescopic rod through a ball joint.

[0013] Optionally, a positioning ring is fixedly connected to the surface of the platform. An arc-shaped groove adapted to the positioning ring is opened on one side of both the splicing platform and the connecting block. Two bubble levels are installed on the surface of the splicing platform. During assembly, the arc-shaped groove fits along the arc of the positioning ring, which can prevent lateral misalignment or angular offset between the splicing platform and the central platform, and ensure that the surface of each module is flat and the gaps are uniform after splicing.

[0014] Optionally, an installation ring is fitted onto the surface of the mounting sleeve, and a rubber pad is fixedly connected to the top of the mounting ring. The top of the rubber pad contacts the bottom of the splicing platform. When the drone lands, the impact force is transmitted to the support components through the platform, and the rubber pad can absorb some of the vibration energy, reducing noise and component wear caused by rigid contact.

[0015] Optionally, the bottom of the support leg is fixedly connected to an anti-slip pad, and the surface of the anti-slip pad is provided with anti-slip texture. The anti-slip pad, in conjunction with the anti-slip texture on the surface, can significantly increase the friction with the ground and effectively prevent the platform from slipping due to the impact force of the drone's take-off and landing or the effect of crosswind.

[0016] Optionally, a pressing plate and a knob are respectively installed at one end of the pressing rod and the other end of the threaded rod. The surface of the pressing plate is provided with a circular groove, and the surface of the knob is provided with a knurled groove. The pressing plate at the end of the pressing rod increases the area for hand application, and the knurled groove on the surface of the knob increases the friction between the hand and the knob.

[0017] Optionally, a limiting block is fixedly connected to the surface of the telescopic rod, and a limiting groove adapted to the limiting block is opened on the inner side wall of the mounting sleeve. The limiting block is movably connected to the inside of the limiting groove. The limiting block can limit the maximum extension length of the telescopic rod and prevent the telescopic rod from being completely pulled out of the mounting sleeve due to operational errors, resulting in component loss or support failure.

[0018] (III) Beneficial Effects

[0019] This utility model provides a drone take-off and landing assistance device, which has the following beneficial effects:

[0020] 1. This drone take-off and landing assistance device breaks down the overall platform into one central platform and four independent splicing platforms. Each module is small in size and light in weight, supporting both single-person backpack carrying and multi-person collaborative transport. It can easily traverse complex terrains such as mountain forest trails and farmland furrows. Upon arrival at the site, assembly is completed through protrusions and grooves and spring-loaded locking blocks, avoiding delays caused by complex assembly processes. The disassembled modules are easy to store and can be directly placed into the drone's toolbox, reducing additional storage space. This transforms the assistance device from a traditional bulky device into a lightweight and portable tool, reducing labor transportation costs and operational preparation time.

[0021] 2. This drone take-off and landing assistance device allows for operation by rotating the knob to loosen the positioning block, pulling the telescopic rod to adjust the height, and rotating the knob in the opposite direction to lock the positioning block. The four sets of support legs can adapt to different ground heights. Together with the bubble level on the splicing platform surface, it can quickly calibrate the platform to a level state, preventing the center of gravity of the drone from shifting due to platform tilt. The ball joint connection structure at the bottom of the telescopic rod allows the legs to automatically adjust the contact angle with the tilted ground, ensuring that the anti-slip pads at the bottom of the legs are fully in contact with the ground, greatly enhancing the support stability and preventing the platform from sliding due to reaction force during drone take-off or shifting due to impact force during landing.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 4 The present invention provides a technical solution: a drone take-off and landing auxiliary device, including a platform 1, splicing platforms 101 are provided around the platform 1, a connecting component 2 is provided between two splicing platforms 101, and a threaded groove is provided at the bottom of each splicing platform 101, and a support component 3 is provided inside the threaded groove.

[0029] The connecting component 2 includes a connecting block 201 disposed on one side of two splicing platforms 101. Both sides of the connecting block 201 are provided with protrusions. The two splicing platforms 101 are provided with grooves that are adapted to the protrusions on one side of each other. The connecting block 201 has a cavity inside. The inner wall of the cavity is movably connected to a movable plate 202. A spring 203 is connected between one side of the movable plate 202 and the inner wall of the cavity. Trapezoidal blocks 204 are installed at the top and bottom of the other side of the movable plate 202. The inner walls of the two grooves are provided with slots that are adapted to the trapezoidal blocks 204. A pressing rod 205 is installed at the center of the other side of the movable plate 202.

[0030] The support assembly 3 includes a mounting sleeve 301 threaded to the inner wall of a threaded groove. A telescopic rod 302 is movably connected to the inner wall of the mounting sleeve 301. A threaded hole is provided at the bottom of the surface of the mounting sleeve 301. A threaded rod 303 is threaded to the inner wall of the threaded hole. A connecting plate 304 is installed at one end of the threaded rod 303. A positioning block 305 is fixedly connected to one side of the connecting plate 304. A plurality of positioning grooves that are adapted to the positioning block 305 are provided on the surface of the telescopic rod 302. A support foot 307 is connected to the bottom of the telescopic rod 302 through a ball head 306.

[0031] The surface of platform 1 is fixedly connected with a positioning ring 4. Both the splicing platform 101 and the connecting block 201 have arc-shaped grooves on one side that are adapted to the positioning ring 4. Two bubble levels 5 are installed on the surface of the splicing platform 101. During assembly, the arc-shaped groove fits along the arc of the positioning ring 4, which can prevent lateral misalignment or angular displacement between the splicing platform 101 and the central platform 1, and ensure that the surface of each module is flat and the gaps are uniform after splicing.

[0032] Mounting sleeve 301 has a mounting ring 6 fitted onto its surface. A rubber pad 7 is fixedly connected to the top of the mounting ring 6. The top of the rubber pad 7 contacts the bottom of the splicing platform 101. When the drone lands, the impact force is transmitted through the platform 1 to the support component 3. The rubber pad 7 can absorb some of the vibration energy, reducing the noise and component wear caused by rigid contact.

[0033] The bottom of the support leg 307 is fixedly connected to an anti-slip pad 8. The surface of the anti-slip pad 8 is provided with anti-slip texture. The anti-slip pad 8, in conjunction with the anti-slip texture on the surface, can significantly increase the friction with the ground and effectively prevent the platform 1 from slipping due to the impact of the drone's take-off and landing or the effect of crosswind.

[0034] A pressing plate 9 and a knob 11 are respectively installed at one end of the pressing rod 205 and the other end of the threaded rod 303. The surface of the pressing plate 9 is provided with a circular groove, and the surface of the knob 11 is provided with a knurled groove. The pressing plate 9 at the end of the pressing rod 205 increases the area for hand application, and the knurled groove on the surface of the knob 11 increases the friction between the hand and the knob 11.

[0035] The surface of the telescopic rod 302 is fixedly connected to a limiting block 10. The inner side wall of the mounting sleeve 301 is provided with a limiting groove that matches the limiting block 10. The limiting block 10 is movably connected to the inside of the limiting groove. The limiting block 10 can limit the maximum extension length of the telescopic rod 302, so as to avoid the telescopic rod 302 being completely pulled out of the mounting sleeve 301 due to operational errors, resulting in component loss or support failure.

[0036] In this invention, the working steps of the device are as follows:

[0037] The first step: The lifting platform 1 consists of a central platform 1 and four peripheral splicing platforms 101. The two splicing platforms 101 have grooves on opposite sides. The connecting block 201 has protrusions on both sides. The protrusions are embedded in the grooves. The spring 203 is in a naturally extended state in the cavity inside the connecting block 201. It pushes the movable plate 202 to move outward, causing the trapezoidal locking block 204 on the movable plate 202 to pop out and lock into the slot on the inner side wall of the groove. Press the pressing rod 205 in the center of the connecting block 201. The pressing rod 205 pushes the movable plate 202 to compress the spring 203. The trapezoidal locking block 204 retracts into the cavity with the movable plate 202 and disengages from the slot. The two modules can be directly separated to the sides. The separated modules can be carried individually or even carried by multiple people. It is suitable for scenarios where it is necessary to carry on foot in mountainous areas and farmland. After arriving at the work site, the connecting components 2 are positioned by the protrusions and grooves and locked by the spring 203 and trapezoidal locking block 204. The assembly is completed to form a complete lifting platform 1.

[0038] Step 2: Rotate the knob 11 at the end of the threaded rod 303 to pull the threaded rod 303 outward. The positioning block 305 at one end of the threaded rod 303 disengages from the positioning groove on the surface of the telescopic rod 302. Depending on the ground height, pull the telescopic rod 302 up or down. In the recessed area of ​​the ground, lengthen the telescopic rod 302 so that the support leg 307 touches the bottom. In the raised area of ​​the ground, shorten the telescopic rod 302 to prevent the platform 1 from tilting. After the height is adjusted to the correct position, rotate the knob 11 in the opposite direction to push the positioning block 305 back into the positioning groove of the corresponding height. The bottom of the telescopic rod 302 is connected to the support leg 307 through the ball head 306. When the support leg 307 contacts the inclined ground, the ball head 306 will automatically adjust the angle according to the ground slope so that the anti-slip pad 8 of the support leg 307 is completely in contact with the ground.
