Description

TECHNICAL FIELD

[0001] The utility model relates to an unmanned plane parking platform technical field, concretely relates to an unmanned plane parking positioning type platform. BACKGROUND

[0002] At present, the precision of landing of unmanned aerial vehicles has become a key problem as the application of unmanned aerial vehicles is increasingly widespread. The existing unmanned aerial vehicle parking systems usually rely on GPS or RTK systems for positioning. However, due to the errors of GPS and RTK systems, the unmanned aerial vehicles cannot be accurately parked at the designated location when landing. Such errors may cause the unmanned aerial vehicles to fail to accurately dock with the charging device, and even cause damage to the unmanned aerial vehicles when the landing platform is retracted. Some unmanned aerial vehicle parking systems in the prior art have complex structures, high costs, and low reliability. Therefore, there is an urgent need for a mechanical structure that can automatically correct the parking position of an unmanned aerial vehicle to ensure that the unmanned aerial vehicle can be accurately parked at the center of the hangar for easy charging and maintenance.

[0003] There are mainly the following solutions to the deviation of the parking position of unmanned aerial vehicles in the existing market:

[0004] Manual intervention: The operator manually adjusts the landing position of the unmanned aerial vehicle through a remote control. This method requires the operator to have high operating skills and attention, has high labor costs, and is low in efficiency. At the same time, human operation is easily affected by external factors (such as weather, operator fatigue, etc.), resulting in large errors and unable to guarantee the precision of each landing.

[0005] Partially automatic positioning device: uses a complex visual recognition system and multiple drive mechanisms to correct the landing position of the unmanned aerial vehicle. Although this type of device achieves automation to some extent, it has a complex structure and high cost. The complex visual recognition system requires high-precision cameras and powerful image processing capabilities, increasing the hardware cost and instability of the system. The multiple drive mechanisms not only increase energy consumption, but also make the maintenance of the device more difficult and reduce the reliability. In addition, these devices often have high requirements for the environment, and in poor light or complex environments, the positioning accuracy will be severely affected, the positioning accuracy is not enough, which not only affects the charging function of the unmanned aerial vehicle, but also affects the stability of the charging of the unmanned aerial vehicle because the unmanned aerial vehicle is not completely fixed. SUMMARY

[0006] The utility model aims at providing an unmanned aerial vehicle parking positioning type platform with high positioning accuracy.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme:

[0008] A drone parking and positioning platform includes a housing. The top of the housing has a supporting top plate, and the surface of the supporting top plate has a flat-bottomed groove for drone parking. A charging through hole is located in the center of the flat-bottomed groove. The surface of the supporting top plate, located at the rear and front sides of the flat-bottomed groove, respectively, has elongated rear sliding holes and elongated front sliding holes. Rear sliders A and B are housed in the elongated rear sliding holes, and front sliders A and B are housed in the elongated front sliding holes. A transverse positioning rod A and a transverse positioning rod B are located above the supporting top plate. The two ends of the transverse positioning rod A are fixed to the rear slider A and the front slider B, respectively, and the two ends of the transverse positioning rod B are fixed to the rear slider B and the front slider B, respectively. The surface of the supporting top plate, located at the left and right sides of the flat-bottomed groove, respectively, has elongated left sliding holes and elongated right sliding holes. Left sliders A and B are housed in the elongated left sliding holes, and right sliders A and B are housed in the elongated right sliding holes.

The two ends of the longitudinal positioning rod A are fixed to the left slider A and right slider B, respectively, and the two ends of the longitudinal positioning rod B are fixed to the left slider B and right slider B, respectively. The longitudinal positioning rods A and B are located above the transverse positioning rods A and B. Long strip-shaped pressure blocks are provided on the bottom surfaces of the transverse positioning rods A and B to press down the support feet of the drone and prevent the drone from moving freely. The housing contains a servo motor and a transmission mechanism. The servo motor drives the rear slider A, rear slider B, front slider A, front slider B, left slider A, left slider B, right slider A, and right slider B simultaneously through the transmission mechanism, so as to drive the transverse positioning rods A and B to move towards each other and the longitudinal positioning rods A and B to move towards each other, so as to push the drone to position it at the center of the flat-bottomed groove for drone parking.

[0009] Furthermore, the elongated pressure block is made of rubber material, and a chamfer is provided on the side of the elongated pressure block facing the charging port. The purpose of the chamfer is to allow the elongated pressure block to move smoothly above the drone's support feet, so as to facilitate pressing down the drone's support feet.

[0010] Furthermore, a ring of drone landing indicator lights is distributed around the charging port on the flat-bottomed groove where the drone is parked.

[0011] Furthermore, the housing includes a rotary motor, a turntable, lifting device A, lifting device B, a power charging plug, and a wireless charging pad. The power charging plug and the wireless charging pad are respectively mounted on top of lifting devices A and B, which are situated on the turntable. The turntable is mounted on the output shaft of the rotary motor. When charging with the wireless charging pad, the rotary motor drives the turntable to move the wireless charging pad directly below the charging port. Lifting device B then pushes the wireless charging pad upward through the charging port, bringing it closer to the drone's charging section. When using wired charging, the rotary motor drives the turntable to move the power charging plug directly below the charging port. Lifting device A then pushes the power charging plug upward through the charging port and inserts it into the power charging socket at the bottom of the drone.

[0012] Furthermore, the lifting devices A and B are electric push rods.

[0013] Furthermore, the servo motor and transmission mechanism are mounted and fixed on the lower surface of the supporting top plate.

[0014] Furthermore, the transmission mechanism includes a rear lead screw, a front lead screw, a left lead screw, and a right lead screw. Each of the rear, front, left, and right lead screws has a threaded section A and a threaded section B with opposite thread directions. A servo motor is connected to one end of the rear lead screw via a coupling. The other end of the rear lead screw is connected to one end of the right lead screw via a bevel gear set. The other end of the right lead screw is connected to one end of the front lead screw via a bevel gear set. The other end of the front lead screw is connected to one end of the left lead screw via a bevel gear set. The rear slider A and rear slider B are respectively mounted on the threaded sections A and B of the rear lead screw via nuts. The front slider A and front slider B are respectively mounted on the threaded sections A and B of the front lead screw via nuts. The left slider A and left slider B are respectively mounted on the threaded sections A and B of the left lead screw via nuts. The right slider A and right slider B are respectively mounted on the threaded sections A and B of the right lead screw via nuts.

[0015] Furthermore, the rear slider A, rear slider B, front slider A, front slider B, left slider A, left slider B, right slider A, and right slider B have the same structure. The rear slider A is provided with a through hole, and a nut is provided in the through hole. One end of the nut is provided with a flange, and the flange is fixed to the side of the rear slider A by screws.

[0016] Furthermore, the bottom surface of the flat-bottomed groove for parking the drone is a polished surface, which reduces the resistance when the drone moves and adjusts in the flat-bottomed groove for parking the drone.

[0017] The beneficial effects of this utility model are as follows:

[0018] This application enables precise positioning of the drone through two longitudinal positioning rods and two transverse positioning rods. At the same time, an elongated pressure block is added to the transverse positioning rod to prevent the drone from moving freely, thereby improving the stability of the drone during charging.

[0019] The bottom surface of the drone parking groove in this application is polished, which can greatly reduce the resistance when the drone moves and adjusts in the drone parking groove.

[0020] This application features a ring of drone landing indicator lights distributed around the charging port to help improve the accuracy of the drone's landing position.

[0021] This application adds a wired and wireless charging conversion mechanism inside the housing, enabling automatic wired and wireless charging of the drone and improving its adaptability to different drone models.

[0032] like Figure 1As shown, a drone parking and positioning platform includes a housing 1. The top of the housing 1 is provided with a supporting top plate 2. The surface of the supporting top plate 2 has a drone parking flat-bottom groove 3. A charging through-hole 4 is located in the center of the drone parking flat-bottom groove 3. A ring of drone landing indicator lights 5 is distributed around the charging through-hole 4 on the drone parking flat-bottom groove 3. The surface of the supporting top plate 2, located at the rear and front sides of the drone parking flat-bottom groove 3, respectively, has elongated rear sliding holes 6 and elongated front sliding holes 7. Rear sliders A8 and B9 are located in the elongated rear sliding hole 6, and front sliders A10 and B11 are located in the elongated front sliding hole 7. A transverse positioning rod A12 and a transverse positioning rod B13 are provided above the supporting top plate 2. The two ends of the transverse positioning rod A12 are fixed to the rear slider A8 and the front slider A10, respectively. The two ends of the transverse positioning rod B13 are fixed to the rear slider B9 and the front slider, respectively. On B11; on the surface of the supporting top plate 2, and on the left and right sides of the UAV parking flat-bottom groove 3, there are respectively a long strip-shaped left sliding hole 14 and a long strip-shaped right sliding hole 15. The long strip-shaped left sliding hole 14 is provided with a left slider A16 and a left slider B17, and the long strip-shaped right sliding hole 15 is provided with a right slider A18 and a right slider B19. Above the supporting top plate 2, there are longitudinal positioning rods A20 and B21. The two ends of the longitudinal positioning rod A20 are respectively fixed. The longitudinal positioning rod B21 is fixed at both ends to the left slider A17 and right slider B19, respectively, on the left slider A16 and right slider A18. The longitudinal positioning rods A20 and B21 are located above the transverse positioning rods A12 and B13. Elongated pressure blocks 22 are provided on the bottom surfaces of the transverse positioning rods A12 and B13 to hold down the drone's support feet and prevent free movement. The bottom surface of the drone parking groove is polished to reduce resistance when the drone moves and adjusts within the groove. In this embodiment, two longitudinal positioning rods and two transverse positioning rods are installed, enabling precise positioning of the drone. The addition of elongated pressure blocks on the transverse positioning rods further prevents free movement, improving the stability of the drone during charging.

[0033] like Figure 2 As shown, the elongated pressure block 22 is made of rubber material, and a chamfer 23 is provided on the side of the elongated pressure block 22 facing the charging through hole 4. The function of the chamfer 23 is to allow the elongated pressure block to move smoothly above the support feet of the drone, so as to press down the support feet of the drone and make the drone more stable during charging operations.

[0034] like Figure 3As shown, the housing 1 is equipped with a servo motor 24 and a transmission mechanism. Specifically, the servo motor 24 and the transmission mechanism are mounted and fixed on the lower surface of the supporting top plate 2. The transmission mechanism includes a rear lead screw 25, a front lead screw 26, a left lead screw 27, and a right lead screw 28. Each of the rear lead screw 25, front lead screw 26, left lead screw 27, and right lead screw 28 has a threaded section A and a threaded section B with opposite thread directions. The servo motor 24 is connected to one end of the rear lead screw 25 via a coupling 29. The other end of the rear lead screw 25 is connected to one end of the right lead screw 28 via a bevel gear set. The other end of the right lead screw 28 is connected to the right lead screw 28 via a bevel gear set. The wheel assembly is connected to one end of the front lead screw 26, and the other end of the front lead screw 26 is connected to one end of the left lead screw 27 via a bevel gear set. The rear sliders A8 and B9 are respectively mounted on the threaded sections A and B of the rear lead screw 25 via nuts. The front sliders A10 and B11 are respectively mounted on the threaded sections A and B of the front lead screw 26 via nuts. The left sliders A16 and B17 are respectively mounted on the threaded sections A and B of the left lead screw 27 via nuts. The right sliders A18 and B19 are respectively mounted on the threaded sections A and B of the right lead screw 28 via nuts. This transmission mechanism has a simple structure, uses a single drive source to achieve overall operation, and ensures motion stability through mechanical structure, thereby reducing costs and improving the reliability of the UAV platform.

[0035] Servo motor 24 simultaneously drives rear slider A8, rear slider B9, front slider A10, front slider B11, left slider A16, left slider B17, right slider A18, and right slider B19 via a transmission mechanism. This causes the lateral positioning rods A and B to move in opposite directions, as well as the longitudinal positioning rods A and B to move in opposite directions, thus positioning the drone at the center of the flat-bottomed groove where it is parked. When the servo motor rotates, the front lead screw and the rear lead screw rotate in opposite directions, and the left lead screw and the right lead screw rotate in opposite directions. The sliders connected to both ends of the same positioning rod move in the same direction, meaning that along the direction of the positioning rod, the sliders simultaneously compress or stretch the positioning rod. This ensures that the two sliders do not have relative angular displacement with respect to the supporting top plate, and that the sliders do not contact or rub against the supporting top plate. In other words, when the servo motor outputs torque in different directions, the sliders will not sway left or right.

[0036] like Figure 4 As shown, the rear slider A8, rear slider B9, front slider A10, front slider B11, left slider A16, left slider B17, right slider A18, and right slider B19 have the same structure. The rear slider A8 is provided with a through hole 30, and a nut 31 is provided in the through hole 30. One end of the nut 31 is provided with a flange 32, and the flange 32 is fixed to the side of the rear slider A8 by screws 33.

[0037] like Figure 5 As shown, the housing contains a rotary motor 34, a turntable 35, a lifting device A36, a lifting device B37, a power charging plug 38, and a wireless charging pad 39. The power charging plug 38 and the wireless charging pad 39 are respectively mounted on the top of the lifting devices A36 and B37. The lifting devices A36 and B37 are located on the turntable 35, which is mounted on the output shaft of the rotary motor 34. When charging with the wireless charging pad, the rotary motor 34 drives the turntable 35 to move the wireless charging pad 39 directly below the charging hole 4. The lifting device B pushes the wireless charging pad upward through the charging hole 4 so that the wireless charging pad 39 is close to the charging part of the drone. When charging with a wired connection, the rotary motor 34 drives the turntable 35 to move the power charging plug 38 directly below the charging hole 4. The lifting device A36 pushes the power charging plug upward through the charging hole 4 and inserts it into the power charging socket at the bottom of the drone.

[0038] In this embodiment, the lifting device A36 and the lifting device B37 are electric push rods.

[0039] Furthermore, those skilled in the art can combine and integrate the different embodiments or examples described herein, as well as the features of those different embodiments or examples, without contradiction. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
