Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an adjusting device and a unmanned aerial vehicle. 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] During the assembly process of the drone, the angle of the propeller blade needs to be adjusted. The existing adjustment method usually arranges a fixing groove on the propeller seat of the drone, inserts the root of the propeller blade into the fixing groove, and then uses a fixing piece to fix it. The specific position of the fixing groove is used to ensure that the propeller blade forms a specific angle after installation.

[0004] However, due to the limitation of the position of the fixing slot, the propeller blade can only be fixed at one angle and cannot be adjusted to other angles. When it is necessary to adjust to other angles, the propeller seat needs to be replaced. Therefore, the existing method of adjusting the propeller blade angle is relatively simple and the operation process is extremely inconvenient. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an adjustment device and a drone to solve the technical problem in the background technology that the existing propeller seat can only fix the propeller blades at one angle. When it needs to be adjusted to other angles, the propeller seat needs to be replaced. Therefore, the existing method of adjusting the propeller blade angle is relatively single and the operation process is extremely inconvenient.

[0006] The utility model provides an adjustment device, which is used to be installed on a drone, and the drone includes a propeller seat, a propeller root, and a fixing member for connecting the propeller root and the propeller seat;

[0007] The adjustment device comprises a special-shaped hole provided on the blade root, wherein the special-shaped hole comprises two special-shaped parts which are connected to each other, and the two special-shaped parts gradually increase from small to large at one end close to each other, so as to form a first adjustment space at one end close to each other and form a second adjustment space at one end far away from each other;

[0008] Wherein, the first adjustment space is opposite to the middle part of the fixing member, and the second adjustment space is opposite to the end part of the fixing member.

[0009] Furthermore, the special-shaped hole includes a first special-shaped portion and a second special-shaped portion which are interconnected.

[0010] Furthermore, the first special-shaped portion includes a first end and a second end, and the size of the first end extends from large to small toward the second end to form a second adjustment space on the first special-shaped portion for the first end of the fixing member to move.

[0011] Furthermore, the second special-shaped portion includes a third end and a fourth end, and the size of the third end extends from large to small toward the fourth end to form a second adjustment space on the second special-shaped portion for the second end of the fixing member to move.

[0012] Furthermore, the second end and the fourth end are connected to each other to jointly form the first adjustment space.

[0013] Furthermore, the size of the first adjustment space is smaller than the size of the second adjustment space.

[0014] Another aspect of the present invention is to provide an unmanned aerial vehicle, comprising a propeller seat, a propeller root, a fixing assembly and the above-mentioned adjustment device, wherein the adjustment device is arranged on the propeller root.

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

[0016] By installing the adjustment device in the utility model in an existing UAV, the angle of the blade can be adjusted without replacing the propeller seat. In the utility model, the adjustment device includes a special-shaped hole arranged on the propeller root, and the special-shaped hole includes two special-shaped parts that are interconnected. The ends of the two special-shaped parts that are close to each other gradually increase from small to large toward the other end, so as to jointly form a first adjustment space at the ends of the two special-shaped parts that are close to each other, and respectively form a second adjustment space at the ends of the two special-shaped parts that are far away from each other. Through the first adjustment space and the second adjustment space, when the angle of the blade is adjusted, the propeller root located at the root of the blade rotates with the blade. By using the first adjustment space and the second adjustment space, the end and the middle part of the fixing member can move relative to the first adjustment space and the second adjustment space, so that the angle of the propeller root can be adjusted, thereby solving the technical problem that the existing propeller seat can only fix the blade at one angle, and when it needs to be adjusted to other angles, the propeller seat needs to be replaced, and the operation process is extremely inconvenient.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] First embodiment

[0025] See also Figures 1 to 3 , which shows an adjustment device in an embodiment of the present utility model, the adjustment device 100 is used to be installed on a drone 200, and the drone 200 includes a propeller seat 210, a propeller root 220, and a fixing member 230 for connecting the propeller root 220 and the propeller seat 210;

[0026] The adjustment device 100 includes a special-shaped hole 110 provided on the blade root 220. The special-shaped hole 110 includes two special-shaped parts that are connected to each other. The two special-shaped parts are gradually increased from small to large at one end close to each other, so as to form a first adjustment space 113 at one end close to each other and form a second adjustment space 114 at one end far away from each other.

[0027] The first adjustment space 113 is opposite to the middle of the fixing member 230 , and the second adjustment space 114 is opposite to the end of the fixing member 230 .

[0028] It should be noted that, in this embodiment, the special-shaped hole 110 includes a first special-shaped portion 111 and a second special-shaped portion 112 that are interconnected.

[0029] Specifically, the first shaped portion 111 includes a first end 1111 and a second end 1112 , and the size of the first end 1111 extends from large to small toward the second end 1112 to form a second adjustment space 1141 on the first shaped portion 111 for the first fixed end 231 of the fixing member 230 to move.

[0030] The second special-shaped portion 112 includes a third end portion 1121 and a fourth end portion 1122. The size of the third end portion 1121 extends from large to small toward the fourth end portion 1122, so as to form a second second adjustment space 1142 on the second special-shaped portion 112 for the second fixed end 232 of the fixing member 230 to move. It should be noted that the second adjustment space 114 includes the second first adjustment space 1141 and the second second adjustment space 1142.

[0031] The second end 1112 and the fourth end 1122 are connected to each other to form a first adjustment space 113 together.

[0032] It should be noted that the propeller root 220 is the root of the propeller blade, that is, when the propeller blade is adjusting its angle, the propeller blade will drive the propeller root 220 to continue rotating, that is, using the movable space of the second first adjustment space 1141 and the second second adjustment space 1142, so that when the propeller root 220 is rotating, the first fixed end 231 and the second fixed end 232 on the fixing member 230 can respectively perform relative movement in the second first adjustment space 1141 and the second second adjustment space 1142. It should be noted that the first fixed end 231 and the second fixed end 232 are the ends of the fixing member 230, which are specifically fan-shaped and movable, and the fixing member 230 is fixed. The middle part of the fixed part 230 corresponds to the first adjustment space 113, that is, the relatively small range of movement, and the sizes of the first adjustment space 113 and the second adjustment space 114 are used to limit the rotation of the propeller root 200. At the same time, the overall strength of the propeller root 220 can be guaranteed to avoid the insufficient strength of the original propeller root 220 due to the setting of the special-shaped hole 110. Through this setting, the problem that the existing propeller seat 210 can only fix the propeller blade at one angle and the propeller seat 210 needs to be replaced when it needs to be adjusted to other angles is solved. Therefore, the existing method of adjusting the propeller blade angle is relatively single and the operation process is extremely inconvenient.

[0033] It should also be noted that the paddle seat 210 is divided into two upper and lower seat bodies, and the upper seat body and the lower seat body are fixed by multiple bolts. The fixing part 230 in this embodiment can also be used. That is, when the paddle root 220 is fixed, it is fixed by the cooperation of the upper and lower seat bodies. Since the fixing method of the paddle seat 210 and the paddle root 220 belongs to the conventional existing technology in the field, it is not specially limited here.

[0034] Furthermore, the size of the first adjustment space 113 is smaller than the size of the second adjustment space 114 .

[0035] In summary, an adjustment device in an embodiment of the present invention has at least the following beneficial effects compared to the prior art method for adjusting the blades:

[0036] By installing the adjustment device 100 in the utility model in the existing UAV 200, the angle of the blade can be adjusted without replacing the propeller seat 210. In the utility model, the adjustment device 100 includes a special-shaped hole 110 arranged on the propeller root 220, and the special-shaped hole 110 includes two interconnected special-shaped parts, and the ends of the two special-shaped parts close to each other gradually increase from small to large toward the other end, so as to form a first adjustment space 113 at the ends of the two special-shaped parts close to each other, and form a second adjustment space 114 at the ends of the two special-shaped parts away from each other. Through the first adjustment space 113 and the second adjustment space 114, when the angle of the blade is adjusted, the blade root 220 located at the root of the blade rotates with the blade, and the first adjustment space 113 and the second adjustment space 114 are utilized so that the end and the middle part of the fixing member 230 can move relative to the first adjustment space 113 and the second adjustment space 114, so that the angle of the blade root 220 can be adjusted, thereby solving the technical problem that the existing blade seat 210 can only fix the blade at one angle. When it needs to be adjusted to other angles, the blade seat 210 needs to be replaced, and the operation process is extremely inconvenient.

[0039] Specifically, the adjusting device 100 is disposed on the propeller root 220 , and the adjusting device 100 can realize the fixing function of the propeller blade after adjusting the angle.

[0040] In summary, the drone in the second embodiment of the present invention has at least the following beneficial effects compared to the adjustment device in the first embodiment:

[0041] In this embodiment, by installing the adjustment device 100 in the first embodiment on a traditional UAV 200, it is convenient to adjust the angle of the blades on the UAV 200, thereby achieving an effect of convenient adjustment.
