Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a battery anti-drop mechanism for unmanned aerial vehicles in flight state. Background Art

[0002] Unmanned aerial vehicle, also known as drone, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. Due to its small size, drone has strong maneuverability. For the sake of practicality, the batteries of existing drones are usually installed as single units to facilitate replacement by staff. When the drone completes some more maneuverable flight actions, the batteries installed inside the drone will inevitably become loose, resulting in the battery falling and being damaged. This requires the use of a drone flight state battery anti-drop mechanism, so an existing drone flight state battery anti-drop mechanism has been continuously innovated and developed. Therefore, it can be seen that the current drone flight state battery anti-drop mechanism basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN218513564U discloses an anti-drop drone battery assembly, including a shell, a battery pack and a buffer member; the shell is provided with at least one battery compartment, each of which is provided with a battery pack, and the battery pack is slidably connected to the battery compartment, and at least one buffer member is provided between the battery pack and the battery compartment; the buffer member includes: a buffer groove, which is provided on the outer wall of the battery pack, and the end of the buffer groove in the length direction away from the battery compartment is through to the outside and open, and the other end opposite is the buffer groove wall; at least one buffer protrusion, which is provided on the compartment wall of the battery compartment and located in the buffer groove, and when the battery pack slides away from the battery compartment, the buffer groove wall can contact and open with the buffer protrusion. The utility model cooperates with the buffer groove and the buffer protrusion, and when the battery pack leaves the battery compartment, the buffer groove wall can engage with the buffer protrusion to play the role of buffering the battery pack, and by providing the buffer groove and the buffer protrusion, the buffer groove wall can engage with the buffer protrusion to play the role of buffering the battery pack.

[0004] However, the buffering effect and buffering limit value of the buffer mechanism of the above-mentioned device are fixed. When the UAV flies to a higher position, its buffer mechanism is difficult to effectively protect the battery, and other mechanisms are still required to prevent the battery from falling. Therefore, a battery anti-drop mechanism for UAV flight state is urgently needed to solve the above problem. Utility Model Content

[0005] The utility model aims to provide a battery anti-drop mechanism for a drone in flight, so as to solve the problem in the background art that the buffer mechanism is difficult to effectively protect the battery when the drone flies to a higher position.

[0006] To achieve the above object, the present utility model provides the following technical solutions, and discloses a battery anti-drop mechanism for the flight state of an unmanned aerial vehicle, including an unmanned aerial vehicle body. The two sides of the unmanned aerial vehicle body are fixedly connected with first connection blocks. The inner wall of the first connection block is rotatably connected with a connecting rod. The top of one end of the connecting rod is rotatably connected with a fan blade;

[0007] A fixing mechanism, including a placement groove. The back surface of the unmanned aerial vehicle body is provided with a placement groove. The inner wall of the placement groove is inserted with a battery body. A card slot is opened at the top of the battery body. One side of the inner wall of the unmanned aerial vehicle body is provided with a movable groove. The inner wall of the movable groove is slidably connected with a connection component. One side of the top of the connection component is fixedly connected with a clamping block, and the surface of the clamping block is inserted into the inner wall of the card slot. A first spring is arranged at the top of the connection component, and the top of the first spring abuts against the inner top wall of the unmanned aerial vehicle body.

[0008] As a preferred technical solution of the present utility model, the bottom of the connecting rod is fixedly connected with a second connection block. The inner wall of the second connection block is rotatably connected with a support column.

[0009] As a preferred technical solution of the present utility model, a chute is opened at the bottom of the connecting rod. The inner wall of the chute is slidably connected with a slider.

[0010] As a preferred technical solution of the present utility model, a second spring is arranged on one side of the inner wall of the chute, and one end of the second spring abuts against one side of the slider. The top of the slider is fixedly connected with a collar 7.

[0011] As a preferred technical solution of the present utility model, a limiting plate is fixedly connected to one side of the battery body. A handle is fixedly connected to one side of the limiting plate.

[0012] As a preferred technical solution of the present utility model, a support rod is fixedly connected to the inner bottom wall of the unmanned aerial vehicle body. The top end of the support rod is fixedly connected with an electronic component assembly.

[0013] As a preferred technical solution of the present utility model, a diversion plate is fixedly connected to the top of the back surface of the unmanned aerial vehicle body. The diversion plate is arc-shaped and is located above the opening of the placement groove.

[0014] As a preferred technical solution of the present utility model, the first connection block can rotate the groove at the top to adjust the tightness of the connecting rod. The middle of the connecting rod has a curvature. The first connection blocks on both sides of the front surface of the unmanned aerial vehicle body and the first connection blocks on both sides of the back surface of the unmanned aerial vehicle body are on the same horizontal line.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] In the present utility model, the battery body is inserted into the placement groove, and the spring pushes the clamping block downward to engage with the clamping groove, thereby fixing the battery body in the placement groove. Since one side of the bottom of the clamping block has a curvature, when the battery body comes into contact with it, the curvature of the clamping block can push it into the movable groove. When installing the battery body, no other operation steps are required, and when disassembling the battery, it can also be directly disassembled by pressing the connection component, making the disassembly and replacement of the battery relatively convenient, effectively improving the usability of the device. Moreover, due to the gravity of the clamping block itself and the elastic force of the spring, when the drone performs a rolling flight, the battery body can also be fixed, effectively preventing the battery from falling during flight.

[0017] In the present utility model, the support column is rotated out from the bottom of the second connection block to keep the support column in a vertical state, which can play a supporting role when the drone lands. After the drone is used, the support column is rotated to fix the collar, and then the connecting rod is rotated to both sides of the drone, thereby accommodating the flight mechanism and the support mechanism, reducing the space occupied by the drone, facilitating the storage and carrying of the drone, and effectively improving the practicality of the device.

[0028] Please refer to Figure 1 , Figure 6 and Figure 7 , a battery anti-falling mechanism for the flight state of a UAV: comprising a UAV body 1, first connection blocks 2 are fixedly connected to both sides of the UAV body 1, a connecting rod 3 is rotatably connected to the inner wall of the first connection block 2, and the top of one end of the connecting rod 3 is rotatably connected to a fan blade 4;

[0029] Fixing mechanism, comprising a placement groove 5, a placement groove 5 is opened on the back of the UAV body 1, a battery body 6 is inserted into the inner wall of the placement groove 5, a card slot 7 is opened at the top of the battery body 6, a movable groove 8 is opened on one side of the inner wall of the UAV body 1, a connection component 9 is slidably connected to the inner wall of the movable groove 8, a clamping block 10 is fixedly connected to one side of the top of the connection component 9, and the surface of the clamping block 10 is inserted into the inner wall of the card slot 7. A first spring 11 is arranged on the top of the connection component 9, and the top of the first spring 11 abuts against the inner top wall of the UAV body 1.

[0030] Before using the battery anti-falling mechanism in the flight state of the drone, first insert the battery body 6 into the placement slot 5, so that the top of the battery body 6 touches the arc-shaped side of the latch 10. Push the latch 10 into the movable slot 8, and then after the battery body 6 is completely inserted into the placement slot 5, the elastic force of the first spring 11 pushes the connection component 9 to descend. The descent of the connection component 9 thus pushes the latch 10 at the bottom to descend. After the latch 10 descends into the card slot 7, the battery body 6 is fixed. The battery body 6 powers the drone body 1. Then rotate the connecting rod 3 out of the first connecting block 2, and then rotate the groove at the top of the first connecting block 2 to adjust the tightness of the rotation of the connecting rod 3, so as to fix the rotation angle of the connecting rod 3. The battery body 6 powers the fan blades 4, so that the fan blades 4 rotate to provide power for the drone body 1 and make it fly. When the battery body 6 needs to be replaced, first press the connection component 9 above the device, so that the connection component 9 drives the latch 10 to rise. After the latch 10 is removed from the card slot 7, take out the battery body 6 from the placement slot 5 and then replace the battery body 6.

[0031] Please refer to Figure 4 , Figure 5 and Figure 8 , a second connecting block 12 is fixedly connected to the bottom of the connecting rod 3. A support column 13 is rotatably connected to the inner wall of the second connecting block 12. A sliding groove 14 is opened at the bottom of the connecting rod 3. A sliding block 15 is slidably connected to the inner wall of the sliding groove 14. A second spring 16 is arranged on one side of the inner wall of the sliding groove 14, and one end of the second spring 16 abuts against one side of the sliding block 15. A collar 17 is fixedly connected to the top of the sliding block 15.

[0032] Before using the battery anti-falling mechanism in the flight state of the drone, first push the collar 17 towards one side of the drone body 1, and then rotate the support column 13 so that the support column 13 rotates in the second connecting block 12. Adjust the support column 13 to a vertical state, and then raise the groove on one side of the second connecting block 12 to fix the tightness of the support column 13. When the drone body 1 descends, the four support columns 13 can support the bottom of the connecting rod 3, thereby supporting the drone body 1. After using the device, rotate one side of the support column 13 to one side of the collar 17. The second spring 16 pushes the sliding block 15 to slide in the sliding groove 14, and the sliding of the sliding block 15 drives the collar 17 to move. Move the collar 17 to the surface of the support column 13, thereby fixing the support column 13 to the inner wall of the collar 17.

[0033] Please refer to Figure 3 and Figure 6, on one side of the battery body 6, a limiting plate 18 is fixedly connected, on one side of the limiting plate 18, a handle 19 is fixedly connected, on the inner bottom wall of the drone body 1, a support rod 20 is fixedly connected, and at the top of the support rod 20, an electronic component assembly 21 is fixedly connected.

[0034] The limiting plate 18 can block the gap between the placement groove 5 and the battery body 6, preventing rainwater from seeping into the gap between the placement groove 5 and the battery body 6. The support rod 20 can support the bottom of the electronic component assembly 21.

[0035] Please refer to Figure 2 and Figure 4 , at the top of the back of the drone body 1, a diversion plate 22 is fixedly connected. The diversion plate 22 is arc-shaped and is located above the opening of the placement groove 5. The top groove of the first connecting block 2 can rotate to adjust the tightness of the connecting rod 3. The middle of the connecting rod 3 has a curvature. The first connecting blocks 2 on both sides of the front of the drone body 1 and the first connecting blocks 2 on both sides of the back of the drone body 1 are on the same horizontal line.

[0036] The diversion plate 22 can block rainwater and sunlight on the top of the battery body 6. By rotating the connecting rod 3, the connecting rod 3 can be made to fit on both sides of the drone body 1, thereby storing the connecting rod 3. Moreover, the front and rear connecting rods 3 are at different heights and can be staggered to avoid interference between the two groups of connecting rods 3 during storage.

[0037] Working principle: When using the battery anti-drop mechanism of the drone in the flight state, first hold the handle 19 and insert the battery body 6 into the placement groove 5. The battery body 6 is fixed by the clamping block 10, and the battery body 6 supplies power to the drone body 1. Then rotate the connecting rod 3 to both sides of the drone body 1. After rotating the support column 13 to the vertical state, the rotation of the fan blade 4 drives the drone body 1 to fly. When the drone body 1 lands, the support column 13 at the bottom can support the drone body 1, and after use, the connecting rod 3 and the support column 13 can be stored.
