Description

Technical Field

[0001] This utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to the technical field of spiral support structures. Background Technology

[0002] The propeller support of a drone refers to the structural component that connects the propeller and the fuselage; it is also known as the drone arm.

[0003] As described in the patent document with announcement number CN221438412U, the spiral bracket is only connected and fixed to the drone body through one end, and the connection strength is not high. As shown in the patent document with announcement number CN221189124U, the spiral bracket is generally a slender rod or tube, and it experiences greater resistance when rising. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a drone spiral support that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a drone propeller support, comprising a support body, which is composed of four centrally symmetrical upright support plates. Each upright support plate includes an integrally connected mounting portion and an extension portion. The mounting portions of the four upright support plates enclose an inner frame, and the extension portions of the four upright support plates extend to the outside of the inner frame. The end of the extension portion away from the mounting portion is provided with a mounting plate for mounting a propeller. The end of the mounting portion away from the extension portion is bent inward to form a connecting plate. The connecting plate is connected to an adjacent upright support plate, and a fixing plate is provided on the mounting portion.

[0006] Preferably, the extension has a connection hole corresponding to the connecting plate, and the top of the connection hole has an inclined surface that slopes downward toward the mounting plate.

[0007] Preferably, the mounting plate and the fixing plate are arranged horizontally, and the connecting plate is arranged vertically.

[0008] Preferably, the width of the upright plate support is smaller than the height of the upright plate support.

[0009] Preferably, both the mounting plate and the fixing plate are integrally bent from the upright bracket.

[0010] Preferably, the inner frame is square.

[0011] Preferably, the fixing plate is connected to the mounting part through a side plate, and the bottom sides of the side plate are transitioned by arc edges.

[0012] The beneficial effects of this utility model are as follows: This utility model improves the stability of installation by connecting and fixing the upright plate brackets to each other through connecting plates, and then fixing them to the machine body through the overall inner frame. This solves the problem of stress concentration and poor stability caused by fixing only the end points. The upright plate brackets are designed as thin plate structures, which reduces the resistance to upward movement.

[0013] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0017] See Figure 1 , Figure 2 A drone propeller support includes a support body composed of four centrally symmetrical upright supports 1. Each upright support 1 includes an integrally connected mounting portion 2 and an extension portion 3. The mounting portions 2 of the four upright supports 1 enclose an inner frame 4. The extension portions 3 of the four upright supports 1 extend to the outside of the inner frame 4. The end of the extension portion 3 away from the mounting portion 2 is provided with a mounting plate 5 for mounting a propeller. The end of the mounting portion 2 away from the extension portion 3 is bent inward to form a connecting plate 6. The connecting plate 6 is connected to an adjacent upright support 1. The mounting portion 2 is provided with a fixing plate 7.

[0018] The extension 3 has a connecting hole 8 corresponding to the connecting plate 6. The top of the connecting hole 8 has a slope 9, which slopes downward toward the mounting plate 5.

[0019] The bevel increases the mounting area at the connection hole, improves the stability of the connection, and distributes stress more evenly over a larger area, avoiding stress concentration.

[0020] The mounting plate 5 and the fixing plate 7 are horizontally arranged, and the connecting plate 6 is vertically arranged.

[0021] The fixing plate 7 is located at the midpoint of the mounting part 2.

[0022] The width of the upright support 1 is less than the height of the upright support 1.

[0023] Both the mounting plate 5 and the fixing plate 7 are integrally bent from the upright bracket 1.

[0024] The inner frame 4 is square.

[0025] The fixing plate 7 is connected to the mounting part 2 via the side plate 10, and the bottom sides of the side plate 10 are transitioned by the arc edge 11.

[0026] The curved edge structure strengthens the connection between the side plate and the mounting part, preventing deformation.

[0027] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
