Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to an automatic resetting platform for unmanned aerial vehicles. Background Art

[0002] With the rise of drones, unmanned airports for drones have developed greatly. The drone takes off from the airport platform, returns to the airport after completing the mission, and lands on the platform to charge or replace the battery. To this end, the drone must be accurately landed to the position before takeoff. The landing error of existing drones is about ±10 cm. In order to eliminate the error, accurate reset. Now generally use a "well" shaped manipulator resetter. That is, after the drone lands, the four mechanical arms on the left and right and the front and back move to the middle, pushing the drone to the middle position at takeoff to achieve accurate reset. And use the mechanical arm to press down the drone's feet to fix the drone to prevent wind and other disturbances from causing the drone to deviate. The following defects exist in the resetting of drones by manipulators:

[0003] 1. The structure of the manipulator is complex and the cost is high;

[0004] 2. The manipulator needs to occupy a large installation space, which increases the space occupied by the entire platform;

[0005] 3. Resetting by manipulator is troublesome and requires manual monitoring, making it difficult to achieve automatic reset;

[0006] 4. After resetting, you need to wait for the robotic arm to release before taking off, which is inconvenient.

[0007] Moreover, after the drone is reset, the propeller of the drone is prone to rotate under the action of wind, and there is a lack of a limiting device for the propeller, which can easily cause the drone to shake, and even the rotating propeller may damage other objects. Summary of the invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a drone automatic reset platform which has a simple structure, occupies little space, has low cost, can enable the drone to automatically reset and facilitates the drone to take off.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] An automatic reset platform for unmanned aerial vehicles is applied to unmanned aerial vehicles with four universal wheels at the bottom, comprising a support platform, a reset groove which is recessed downward is provided in the middle of the support platform, positioning parts are respectively provided at the four corners of the bottom surface of the reset groove, and a guide surface is connected between each two adjacent positioning parts, the middle part of the guide surface is higher than the two ends, and the side surface of the reset groove is a gradient surface connected to the outer edge of the guide surface.

[0011] As a further improvement of the above technical solution:

[0012] The positioning portion is provided with a positioning hole for the universal wheel of the drone to be inserted into.

[0013] A limiting portion with a high middle portion and low surrounding portions is arranged in the area enclosed by each of the guiding surfaces.

[0014] The periphery of the limiting portion is smoothly connected to the inner edges of each guiding surface.

[0015] A lifting seat is arranged at the bottom of the supporting platform.

[0016] The automatic reset platform of the UAV also includes a propeller restraining mechanism for limiting the rotation of the UAV threaded propeller, and the propeller restraining mechanism includes a lifting support and a propeller restraining sleeve, the lifting support is arranged on the support platform, and the propeller restraining sleeve is arranged on the top of the lifting support.

[0017] There are multiple propeller binding mechanisms, and the lifting supports of each propeller binding mechanism are fixed to the bottom of the support platform and arranged at intervals around the outer circumference of the reset groove. The support platform and the positions corresponding to each propeller binding sleeve are provided with passage holes for the propeller binding sleeve to lift and pass through.

[0018] The propeller restraining sleeve is an arc-shaped body with an opening on one side, and the opening of the propeller restraining sleeve is arranged toward the reset groove.

[0019] The top surface of the propeller sleeve is a guide surface which is high in the middle and inclined toward the opening direction on both sides.

[0020] The automatic reset platform for the UAV also includes a plurality of propeller-binding mechanisms for limiting the rotation of the UAV threaded propellers, the propeller-binding mechanisms including a fixed support and a propeller-binding sleeve, the fixed support being arranged below the support platform, the propeller-binding sleeve being arranged on the top of the fixed support, the fixed supports of each of the propeller-binding mechanisms being arranged at intervals around the outer circumference of the lifting seat, and the positions of the support platform and each propeller-binding sleeve corresponding to each other are provided with through holes for the propeller sleeves to pass through when being lifted or lowered.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] The automatic reset platform of the unmanned aerial vehicle of the present invention is that the unmanned aerial vehicle lands on the reset groove of the support platform. If the universal wheel of the unmanned aerial vehicle is located on the gradient surface, under the guiding effect of the gradient surface and the action of its own gravity, the universal wheel of the unmanned aerial vehicle will roll along the gradient surface to the guide surface (the four universal wheels are moved to the four guide surfaces respectively), and then, under the guiding effect of the guide surface and the action of its own gravity, the four universal wheels will automatically slide along the corresponding guide surface to the lower positioning part, so as to realize the automatic and accurate reset of gravity. The automatic reset platform of the unmanned aerial vehicle can automatically and accurately reset under the action of its own gravity, and does not need to be equipped with other auxiliary equipment (such as a manipulator) for reset. It has a simple structure, occupies less space, and has low cost. In addition, the universal wheel that falls into the positioning part, because the positioning part is relatively low relative to the surroundings, under the limiting effect of the positioning part on the universal wheel around, the general horizontal wind and disturbance will not cause the unmanned aerial vehicle to be horizontally displaced, so that the unmanned aerial vehicle is stably on the platform. In addition, when the unmanned aerial vehicle takes off, the universal wheel will move vertically upward, and the positioning part has no upward obstruction effect on the universal wheel, so the unmanned aerial vehicle will take off smoothly. The automatic reset platform for unmanned aerial vehicles has a simple structure, occupies little space, has low cost, can enable the unmanned aerial vehicle to achieve automatic reset and facilitates the unmanned aerial vehicle to take off.

[0023] The automatic reset platform for the unmanned aerial vehicle of the present invention can prevent the universal wheel from shaking horizontally under the limiting effect of the positioning hole after the unmanned aerial vehicle is reset, thereby improving the stability of the unmanned aerial vehicle at the reset position.

[0024] The automatic reset platform for unmanned aerial vehicles of the present invention is used when the unmanned aerial vehicle lands on the reset groove of the support platform. If the universal wheels of the unmanned aerial vehicle are located on the limiting portion, the universal wheels of the unmanned aerial vehicle will roll along the top surface of the limiting portion to the guide surface (the four universal wheels move to the four guide surfaces respectively) under the guiding effect of the top surface of the limiting portion and the effect of its own gravity. Of course, there are other shapes of designs for the intervals enclosed by the guide surfaces, as long as the universal wheels falling thereon do not have a horizontal movement limit effect or a downward movement limit effect, so as to ensure that the universal wheels can roll to the guide surface under the effect of their own gravity.

[0025] The automatic reset platform for unmanned aerial vehicles of the present invention is generally covered with an outer cover outside the automatic reset platform for unmanned aerial vehicles to protect the unmanned aerial vehicles. An openable and closable top cover is provided on the top of the outer cover for the entry and exit of the unmanned aerial vehicles. A lifting seat is provided on the bottom of the support platform. Before the unmanned aerial vehicle lands, the top cover is opened, and the lifting seat rises to push the support platform out from the top of the outer cover to wait for the unmanned aerial vehicle to land; after the unmanned aerial vehicle lands and resets, the lifting seat descends, and the support platform descends with it, so that the unmanned aerial vehicle is lowered into the outer cover, and then the outer cover is covered.

[0026] The automatic reset platform for the drone of the present invention has a binding effect on the propeller of the drone after the drone is reset, so as to prevent the propeller from rotating, avoid shaking of the drone due to the rotation of the propeller, and avoid the rotating propeller from damaging other objects.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Embodiment 1:

[0040] Figures 1 to 7An embodiment of the automatic reset platform for unmanned aerial vehicles of the present invention is shown. The automatic reset platform for unmanned aerial vehicles is applied to unmanned aerial vehicles with four universal wheels at the bottom, and comprises a support platform 1. A reset groove 2 which is sunken downward is provided in the middle of the support platform 1. Positioning parts 3 are respectively provided at the four corners of the bottom surface of the reset groove 2. A guide surface 4 is connected between two adjacent positioning parts 3. The middle part of the guide surface 4 is higher than the two ends. The side of the reset groove 2 is a gradient surface 21 connected to the outer edge of the guide surface 4. The middle part of the guide surface 4 is higher than the two ends, that is, the positioning part 3 is lower than the guide surface 4.

[0041] The drone lands on the reset groove 2 of the support platform 1. If the universal wheels of the drone are located on the gradient surface 21, under the guidance of the gradient surface 21 and the action of its own gravity, the universal wheels of the drone will roll along the gradient surface 21 to the guide surface 4 (the four universal wheels are moved to the four guide surfaces 4 respectively). Then, under the guidance of the guide surface 4 and the action of its own gravity, the four universal wheels will automatically slide along the corresponding guide surface 4 to the lower positioning part 3, realizing automatic and precise reset by gravity. This drone automatic reset platform can automatically and accurately reset under the action of its own gravity, and does not need to be equipped with other auxiliary equipment (such as a manipulator) for reset. It has a simple structure, occupies less space, and has low cost. In addition, the universal wheels that fall into the positioning part 3, because the positioning part 3 is relatively low in position relative to the surroundings, under the limiting action of the universal wheels around the positioning part 3, general horizontal wind and disturbance will not cause the drone to shift horizontally, so that the drone is stably on the platform. Moreover, when the drone takes off, the universal wheel will move vertically upward, and the positioning part 3 will not hinder the universal wheel upward, so the drone will take off smoothly. The drone automatic reset platform has a simple structure, occupies less space, has low cost, can realize automatic reset of the drone and facilitates the drone to take off.

[0042] In this embodiment, Figure 5 As shown, the positioning portion 3 is provided with a positioning hole 31 for the universal wheel of the drone to be inserted into. After the drone is reset, the universal wheel is inserted into the positioning hole 31. Under the limiting effect of the positioning hole 31, the universal wheel is further prevented from shaking horizontally, thereby improving the stability of the drone in the reset position.

[0043] In this embodiment, Figure 1 , Figure 4 and Figure 5As shown, a limiting portion 5 with a high middle and low surroundings is provided in the area enclosed by each guiding surface 4. When the drone lands on the reset groove 2 of the support platform 1, if the universal wheel of the drone is located on the limiting portion 5, under the guiding effect of the top surface of the limiting portion 5 and the action of its own gravity, the universal wheel of the drone will roll along the top surface of the limiting portion 5 to the guiding surface 4 (the four universal wheels move to the four guiding surfaces 4 respectively). Of course, there are other shapes for the area enclosed by each guiding surface 4, as long as there is no horizontal movement limiting effect or downward movement limiting effect on the universal wheel falling thereon, so as to ensure that the universal wheel can roll to the guiding surface 4 under the action of its own gravity.

[0044] In this embodiment, the periphery of the limiting portion 5 is smoothly connected to the inner edges of each guiding surface 4. With this design, the universal wheel landing on the limiting portion 5 can smoothly roll onto the guiding surface 4, reducing collision.

[0045] In this embodiment, Figure 4 and Figure 5 As shown, a lifting seat 6 is provided at the bottom of the support platform 1. An outer cover is generally provided outside the automatic reset platform of the drone to protect the drone. A closable top cover is provided on the top of the outer cover for the drone to enter and exit. The lifting seat 6 is provided at the bottom of the support platform 1. Before the drone lands, the top cover is opened, and the lifting seat 6 rises to push the support platform 1 out from the top of the outer cover, waiting for the drone to land; after the drone lands and resets, the lifting seat 6 descends, and the support platform 1 descends with it, lowering the drone into the outer cover, and then the outer cover is closed.

[0046] In this embodiment, Figures 1 to 4 As shown, the automatic reset platform of the UAV further includes a propeller restraining mechanism 7 for limiting the rotation of the propeller of the UAV, and the propeller restraining mechanism 7 includes a lifting support 71 and a propeller restraining sleeve 72, wherein the lifting support 71 is arranged on the support platform 1, and the propeller restraining sleeve 72 is arranged on the top of the lifting support 71. After the reset of the UAV is completed, the lifting support 71 drives the propeller restraining sleeve 72 to rise, so that the propeller restraining sleeve 72 is sleeved on the propeller of the UAV to prevent the propeller from rotating, avoid shaking of the UAV due to the rotation of the propeller, and avoid the rotating propeller from damaging other objects.

[0047] In this embodiment, a plurality of propeller binding mechanisms 7 are provided, and the lifting supports 71 of each propeller binding mechanism 7 are fixed to the bottom of the support platform 1 and are arranged at intervals around the outer circumference of the reset groove 2. The positions of the support platform 1 corresponding to each propeller binding sleeve 72 are provided with through holes 11 for the propeller binding sleeve 72 to pass through and rise and fall. The lifting supports 71 are fixed on the support platform 1 and move with the support platform 1. The lifting supports 71 are fixed to the bottom of the support platform 1 to avoid interfering with the lifting and lowering movement of the UAV. Before the UAV lands, the lifting supports 71 make the propeller binding sleeve 72 be located at a position lower than the top surface of the through hole 11 to avoid the propeller binding sleeve 72 interfering with the landing movement of the UAV. After the UAV is reset, the lifting supports 71 drive the propeller binding sleeve 72 to rise, so that the propeller binding sleeve 72 passes through the through hole 11 and is sleeved on the threaded propeller of the UAV to prevent the threaded propeller from rotating. Of course, in other embodiments, the propeller-binding mechanism 7 can also be arranged on the periphery of the support platform 1, so that the through hole 11 can be avoided. However, the size of the outer cover must be increased to increase the floor space, and it is difficult for the support platform 1 to form an upper and lower partition inside the outer cover, so it is difficult to protect the lifting seat 6 under the support platform 1. Specifically, there are four propeller-binding mechanisms 7, and correspondingly, there are also four through holes 11, which are respectively located at the four corners of the top of the reset groove 2, and are applied to drones with four propellers at the four corners of the top.

[0048] In this embodiment, the propeller cover 72 is an arc-shaped body with an opening 721 on one side, and the opening 721 of the propeller cover 72 is arranged toward the reset groove 2. It is convenient for the outer end of the propeller to be inserted into the propeller cover 72 through the opening 721. The opening 721 is arranged vertically, and the blocking effect on both sides of the opening 721 limits the rotation angle of the propeller, preventing the propeller from rotating or rotating at a large angle.

[0049] In this embodiment, Figure 2 , Figure 6 and Figure 7As shown, the top surface of the propeller sleeve 72 is an introduction surface 722 which is high in the middle and inclined toward the opening 721 on both sides. Applicable to a drone with multiple propellers at the four corners of the top, the top of the drone is generally provided with multiple propellers, which are arranged at intervals around the drone, and the propeller includes two blades 8, one end of each of the two blades 8 can be rotatably arranged on the drone, which is convenient for adjusting the angle between the two blades 8, and there is also an elastic reset member between the two blades 8, so that the two blades 8 are protected in a co-linear state without the action of external force. After the reset of the propeller sleeve 72 is completed, the center of the propeller is directly opposite to the propeller sleeve 72 below, and the lifting support 71 drives the propeller sleeve 72 to rise, so that the top surface of the propeller sleeve 72 contacts the blades 8. As the propeller sleeve 72 continues to rise, under the action of the guide thrust of the introduction surface 722, the two blades 8 of the propeller will be folded toward the direction of the opening 721 of the propeller sleeve 72 until the two blades 8 are stuck in the opening 721 of the propeller sleeve 72. Under the action of the guiding thrust of the introduction surface 722, the propeller can be automatically folded without the help of other external forces. In addition, since the opening 721 of the propeller cover 72 is arranged toward the reset groove 2, after the two blades 8 of the propeller are folded to the opening 721 by central rotation, they are both located on the side of the propeller cover 72 facing the reset groove 2, which reduces the size of the overall structure of the drone and facilitates the drone to descend into the outer cover. Accordingly, the outer cover can also be set smaller, reducing the occupied space.

[0050] In other embodiments, Figure 8 As shown, a rolling element 723, such as a roller, a ball, a bearing, etc., can be set in the middle position of the introduction surface 722 to facilitate the introduction of the two blades 8 of the propeller to the inclined surfaces (curved surfaces) on both sides of the middle of the introduction surface 722, so as to prevent the propeller blades 8 from being stuck in the middle position of the introduction surface 722 and unable to rotate and fold.

[0051] In other embodiments, the lifting support 71 may also be independently arranged relative to the support platform 1 to avoid being affected by the lifting movement of the support platform 1 .

[0052] Embodiment 2:

[0053] Fig. 9 Another embodiment of the automatic reset platform for unmanned aerial vehicles of the present invention is shown. The automatic reset platform for unmanned aerial vehicles is applied to unmanned aerial vehicles with four universal wheels at the bottom, and includes a support platform 1. A reset groove 2 which is recessed downward is provided in the middle of the support platform 1. Positioning parts 3 are provided at the four corners of the bottom surface of the reset groove 2. A guide surface 4 is connected between two adjacent positioning parts 3. The middle part of the guide surface 4 is higher than the two ends. The side of the reset groove 2 is a gradient surface 21 connected to the outer edge of the guide surface 4. The middle part of the guide surface 4 is higher than the two ends, that is, the positioning part 3 is lower than the guide surface 4.

[0054] The drone lands on the reset groove 2 of the support platform 1. If the universal wheels of the drone are located on the gradient surface 21, under the guidance of the gradient surface 21 and the action of its own gravity, the universal wheels of the drone will roll along the gradient surface 21 to the guide surface 4 (the four universal wheels are moved to the four guide surfaces 4 respectively). Then, under the guidance of the guide surface 4 and the action of its own gravity, the four universal wheels will automatically slide along the corresponding guide surface 4 to the lower positioning part 3, realizing automatic and precise reset by gravity. This drone automatic reset platform can automatically and accurately reset under the action of its own gravity, and does not need to be equipped with other auxiliary equipment (such as a manipulator) for reset. It has a simple structure, occupies less space, and has low cost. In addition, the universal wheels that fall into the positioning part 3, because the positioning part 3 is relatively low in position relative to the surroundings, under the limiting action of the universal wheels around the positioning part 3, general horizontal wind and disturbance will not cause the drone to shift horizontally, so that the drone is stably on the platform. Moreover, when the drone takes off, the universal wheel will move vertically upward, and the positioning part 3 will not hinder the universal wheel upward, so the drone will take off smoothly. The drone automatic reset platform has a simple structure, occupies less space, has low cost, can realize automatic reset of the drone and facilitates the drone to take off.

[0055] In this embodiment, the positioning portion 3 is provided with a positioning hole 31 for the universal wheel of the drone to be inserted into. After the drone is reset, the universal wheel is inserted into the positioning hole 31. Under the limiting effect of the positioning hole 31, the universal wheel is further prevented from shaking horizontally, thereby improving the stability of the drone in the reset position.

[0056] In this embodiment, a limiting portion 5 with a high middle and low surroundings is provided in the area enclosed by each guiding surface 4. When the drone lands on the reset groove 2 of the support platform 1, if the universal wheel of the drone is located on the limiting portion 5, under the guiding effect of the top surface of the limiting portion 5 and the action of its own gravity, the universal wheel of the drone will roll along the top surface of the limiting portion 5 to the guiding surface 4 (the four universal wheels move to the four guiding surfaces 4 respectively). Of course, there are other shapes of designs for the area enclosed by each guiding surface 4, as long as there is no horizontal movement limiting effect or downward movement limiting effect on the universal wheel falling thereon, so as to ensure that the universal wheel can roll to the guiding surface 4 under the action of its own gravity.

[0057] In this embodiment, the periphery of the limiting portion 5 is smoothly connected to the inner edges of each guiding surface 4. With this design, the universal wheel landing on the limiting portion 5 can smoothly roll onto the guiding surface 4, reducing collision.

[0058] In this embodiment, a lifting seat 6 is provided at the bottom of the support platform 1. An outer cover is generally provided outside the automatic reset platform of the drone to protect the drone. An openable and closable top cover is provided on the top of the outer cover for the drone to enter and exit. The lifting seat 6 is provided at the bottom of the support platform 1. Before the drone lands, the top cover is opened, and the lifting seat 6 rises to push the support platform 1 out from the top of the outer cover, waiting for the drone to land; after the drone lands and resets, the lifting seat 6 descends, and the support platform 1 descends with it, and the drone is lowered into the outer cover, and then the outer cover is covered.

[0059] In this embodiment, the automatic reset platform of the UAV further includes a propeller binding mechanism 7 for limiting the rotation of the UAV screw propeller, and the propeller binding mechanism 7 includes a fixed support 73 and a propeller binding sleeve 72, the fixed support 73 is arranged below the support platform 1, and the propeller binding sleeve 72 is arranged on the top of the fixed support 73. Before the UAV lands, the top cover is opened, the lifting seat 6 rises to push the support platform 1 out from the top of the outer cover, and waits for the UAV to land. At this time, the propeller binding sleeve 72 is located below the support platform 1 to avoid interfering with the landing of the UAV; after the UAV lands and resets, the lifting seat 6 descends, and the support platform 1 descends with it, and the UAV is lowered into the outer cover. During the descent of the support platform 1, the propeller binding sleeve 72 rises relative to the support platform 1. When the UAV descends to a predetermined position in the outer cover, the propeller of the UAV is covered on the propeller binding sleeve 72 to prevent the screw propeller from rotating. This embodiment is equivalent to the first embodiment, and the fixed support 73 is fixedly arranged and can be arranged at the bottom of the lifting seat 6, which is not affected by the lifting and lowering of the lifting seat 6. The fixed support 73 does not have the lifting function of the lifting support 71, and the structure is simpler and the operation is more convenient.

[0060] In this embodiment, a plurality of propeller tying mechanisms 7 are provided, and fixed supports 73 of each propeller tying mechanism 7 are arranged at intervals around the outer circumference of the lifting base 6. Positions corresponding to the support platform 1 and each propeller tying sleeve 72 are provided with passage holes 11 for the propeller tying sleeve 72 to pass through when being lifted or lowered.

[0061] Of course, in other embodiments, the propeller-binding mechanism 7 can also be located on the periphery of the support platform 1, so that the through hole 11 can be avoided. However, the size of the outer cover must be increased to increase the floor space, and it is difficult for the support platform 1 to form an upper and lower partition inside the outer cover, so it is difficult to protect the lifting seat 6 under the support platform 1. Specifically, there are four propeller-binding mechanisms 7, and correspondingly, there are also four through holes 11, which are respectively located at the four corners of the top of the reset groove 2, and are applied to a drone with four propellers on the top.

[0062] In this embodiment, the propeller cover 72 is an arc-shaped body with an opening 721 on one side, and the opening 721 of the propeller cover 72 is arranged toward the reset groove 2. It is convenient for the outer end of the propeller to be inserted into the propeller cover 72 through the opening 721. The opening 721 is arranged vertically, and the blocking effect on both sides of the opening 721 limits the rotation angle of the propeller, preventing the propeller from rotating or rotating at a large angle.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
