Technical Field

[0001] The utility model discloses a drone blade with a protective structure, and relates to the field of drone blades. Background Art

[0002] Unmanned aerial vehicle, abbreviated as "UAV" in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] In the prior art, drone blades need to rotate at high speed during use. When the drone blades hit objects during high-speed rotation, the drone blades will be damaged. However, in order to avoid this situation, a protective structure needs to be installed on the outside of the drone blades. Traditional drone blade protection structures are made according to the size of the drone blades, and the drone blade protection structure also needs to be specifically made according to the installation position. At the same time, due to the different sizes and lengths of drone blades, the drone blade protection structure cannot be installed as needed, resulting in the problem of poor practicality of the drone blade protection mechanism. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a UAV blade with a protective structure to solve the problems raised in the above-mentioned background technology. The present invention is easy to use, easy to operate, has good stability and high reliability.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a drone blade with a protective structure includes a blade motor, a driving end of the blade motor is fixedly connected to a driving shaft, the outer side of the driving shaft is fixedly connected to a propeller frame, the outer side of the propeller frame is fixedly connected to a propeller blade, the outer side of the blade motor is fixedly connected to a protective mounting frame, one side of the protective mounting frame is fixedly connected to a fixing plate, one side of the fixing plate is threadedly connected to a fixing screw on the front side, the other side of the protective mounting frame is fixedly connected to an adjusting rod, the outer side of the adjusting rod is fixedly connected to an adjusting sleeve, the front side of the adjusting sleeve is threadedly connected to an adjusting screw, the top of the adjusting sleeve is fixedly connected to a support rod, and the top of the support rod is fixedly connected to a protective plate.

[0006] Furthermore, one side of the blade motor is fixedly connected to a cantilever body, and one end of the cantilever body is fixedly connected to a drone body.

[0007] Furthermore, an adjustment opening is provided at one end of the adjustment sleeve, the inner diameter of the adjustment opening is matched with the diameter of the adjustment rod, and the adjustment sleeve is fixedly connected to the adjustment rod via the adjustment opening and the adjustment screw.

[0008] Furthermore, the protective plate has an arc-shaped structure, and the outer surface of the protective plate is smooth.

[0009] Furthermore, four propeller blades are provided, the four propeller blades have the same shape, and the four propeller blades are arranged at equal intervals.

[0010] Furthermore, the adjusting rod is a solid cylindrical structure, and the outer surface of the adjusting rod is smooth.

[0011] The beneficial effects of the utility model are as follows: through the provision of the protective mounting frame, the adjusting rod, the adjusting sleeve and the protective plate, when using the UAV blades with the protective structure, the staff installs the protective mounting frame on the blade motor of the UAV blade, and then firmly fixes the protective mounting frame on the blade motor by twisting the fixing screws on the fixing plate. At the same time, when installing on other blade motors of different models and sizes, the staff adjusts the fixing screws, and the fixing screws can shrink and expand the protective mounting frame through the fixing plate, thereby installing the protective mounting frame on blade motors of different models and sizes. After installation, due to different models, the lengths of the propeller blades are also different. The staff loosens the adjusting screws according to the length of the propeller blades. The joint screw will not press against the adjusting rod. At this time, the staff can push the adjusting sleeve left and right, and the adjusting sleeve will move on the adjusting rod, and drive the protective plate to adjust the position through the support rod. After the position is adjusted, the staff tightens the adjusting screw, and the adjusting screw will press against the adjusting rod, thereby fixing the adjusting sleeve and the adjusting rod. When the blade motor drives the propeller blades on the propeller frame to rotate through the drive shaft, the protective plate will protect the propeller blades. When colliding with an object, the protective plate will play a blocking role. This structural setting enables the UAV blade protection structure to be adjusted according to the size of the UAV blade, and can also be installed on blade motors of different models and sizes, thereby improving the practicability of the UAV blade protection mechanism.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1 and Figure 4 The utility model provides a technical solution: a drone blade with a protective structure includes a blade motor 3, a driving end of the blade motor 3 is fixedly connected to a driving shaft 4, an outer side of the driving shaft 4 is fixedly connected to a propeller frame 5, an outer side of the propeller frame 5 is fixedly connected to a propeller blade 6, an outer side of the blade motor 3 is fixedly connected to a protective mounting frame 7, one side of the protective mounting frame 7 is fixedly connected to a fixing plate 8, a front side of one side of the fixing plate 8 is threadedly connected to a fixing screw 9, an other side of the protective mounting frame 7 is fixedly connected to an adjusting rod 10, an outer side of the adjusting rod 10 is fixedly connected to an adjusting sleeve 11, a front side of the adjusting sleeve 11 is threadedly connected to an adjusting screw 12, a top of the adjusting sleeve 11 is fixedly connected to a supporting rod 13, and a top of the supporting rod 13 is fixedly connected to a protective plate 14.

[0020] Specific implementation method: One side of the blade motor 3 is fixedly connected to the cantilever body 2, and one end of the cantilever body 2 is fixedly connected to the drone body 1. The cantilever body 2 can support the blade motor 3, so that the blade motor 3 can be kept at a certain distance from the drone body 1, so that the propeller blade 6 can operate better.

[0021] Specific implementation method: An adjustment port 1101 is provided at one end of the adjustment sleeve 11, and the inner diameter of the adjustment port 1101 is adapted to the diameter of the adjustment rod 10. The adjustment sleeve 11 is fixedly connected to the adjustment rod 10 through the adjustment port 1101 and the adjustment screw 12. By loosening the adjustment screw 12, the adjustment screw 12 will not support the adjustment rod 10. At this time, the staff can push the adjustment sleeve 11 left and right, and the adjustment sleeve 11 will move on the adjustment rod 10, and the protective plate 14 can be driven to adjust the position through the support rod 13. After the position is adjusted, the staff tightens the adjustment screw 12, and the adjustment screw 12 will support the adjustment rod 10, thereby fixing the adjustment sleeve 11 and the adjustment rod 10.

[0022] Specific implementation method: The protective plate 14 is in an arc-shaped structure, and the outer surface of the protective plate 14 is smooth, so that the protective plate 14 can play a more comprehensive protective role.

[0023] Specific implementation: There are four propeller blades 6, which have the same shape and are arranged equidistantly, so that the propeller blades 6 are more stable during rotation and will not vibrate greatly due to gravity.

[0024] Specific implementation method: The adjusting rod 10 is a solid cylindrical structure, and the outer surface of the adjusting rod 10 is smooth. It pushes the adjusting sleeve 11 left and right, and the adjusting sleeve 11 can move left and right on the adjusting rod 10 more flexibly.

[0025] Working principle: through the provision of the protective mounting frame 7, the adjusting rod 10, the adjusting sleeve 11 and the protective plate 14, when using the UAV blade with the protective structure, the staff installs the protective mounting frame 7 on the blade motor 3 of the UAV blade, and then firmly fixes the protective mounting frame 7 on the blade motor 3 by twisting the fixing screw 9 on the fixing plate 8. When installing on other blade motors 3 of different models and sizes at the same time, the staff adjusts the fixing screw 9, and the fixing screw 9 can shrink and expand the protective mounting frame 7 through the fixing plate 8, so as to install the protective mounting frame 7 on blade motors 3 of different models and sizes. After installation, the lengths of the propeller blades 6 are different due to different models. At the same time, the staff loosens the adjusting screw 12 according to the length of the propeller blade 6, and the adjusting screw 12 will not press against the adjusting rod 10. At this time, the staff can push the adjusting sleeve 11 left and right, and the adjusting sleeve 11 will move on the adjusting rod 10, and drive the protective plate 14 to adjust the position through the support rod 13. After the position is adjusted, the staff tightens the adjusting screw 12, and the adjusting screw 12 will press against the adjusting rod 10, so that the adjusting sleeve 11 and the adjusting rod 10 are fixed together. When the blade motor 3 drives the propeller blade 6 on the propeller frame 5 to rotate through the drive shaft 4, the protective plate 14 will protect the propeller blade 6, and when it hits an object, the protective plate 14 will play a blocking role.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
