[0028] like Figures 1 to 5 As shown, this embodiment provides an aviation unmanned aerial vehicle engine throttle servo mounting bracket assembly, including: a mounting base 10, a servo bracket 20 disposed on the mounting base 10, and a cable bracket 30 disposed on the servo bracket 20.

[0029] like Figures 1 to 4 As shown, the mounting base 10 includes multiple mounting blocks 11 and mounting beams 12.

[0030] In this embodiment, each mounting block 11 is mounted on an engine and positioned near the engine's output end. Each mounting block 11 has multiple threaded grooves 13 on its top wall.

[0031] like Figure 5 As shown, the specific number of mounting blocks 11 depends on the number of engines. One mounting block 11 can be installed above and below each engine, and near the throttle valve.

[0032] In this embodiment, the mounting beam 12 is detachably mounted on the mounting block 11. The mounting beam 12 is located above the engine and its arrangement direction is perpendicular to the axial direction of the engine. The top wall of the mounting beam 12 is provided with two through holes 14, and each of the two through holes 14 is provided with a limiting bolt 15. Each limiting bolt 15 is fixed to the mounting beam 12 by a nut 16.

[0033] like Figure 5 As shown, the mounting beam 12 is preferably L-shaped and inverted on multiple mounting blocks 11.

[0034] In this embodiment, a positioning hole 17 is provided on the mounting beam 12 at the position corresponding to each threaded groove 13, and a first fixing bolt 18 is provided in each positioning hole 17 for fixing the mounting beam 12 to the mounting block 11. The inner wall of the positioning hole 17 is provided with internal thread.

[0035] like Figures 1 to 4 As shown, the servo mount 20 is T-shaped and horizontally mounted on the mounting base 10. The servo mount 20 has a vertical section 21 and a horizontal section 22. The bottom wall of the vertical section 21 is flush with the top wall of the mounting beam 12. U-shaped through slots 23 are formed on both outer sides of the vertical section 21, extending inwards. The two through slots 23 are located above the two through holes 14. The side wall of the horizontal section 22 is flush with the side wall of the mounting beam 12. A mounting hole 24 for placing the servo is formed on the top wall of the horizontal section 22, above the mounting beam 12. The vertical section 21 and horizontal section 22 of the servo mount 20 can be found in the attached instruction manual. Figure 2 Included with instruction manual Figure 3 It is clearly distinguishable and can be seen in the text.

[0036] In this embodiment, the top wall of the horizontal segment 22 is provided with a plurality of mounting holes 25 for fixing the servo motor, located above and below the mounting hole 24. Each mounting hole 25 has an internal thread on its hole wall and a second fixing bolt 26 is provided in each mounting hole 25.

[0037] In this embodiment, a fixing hole 27 is provided on the top wall of the horizontal segment 22 and on one side of the mounting hole 24, and the inner wall of the fixing hole 27 is provided with an internal thread.

[0038] In this embodiment, the bottom wall of the mounting hole 24 and the top wall of the vertical section 21 are located on the same horizontal plane.

[0039] In this embodiment, the distance between the two limiting bolts 15 is greater than the distance between the bottoms of the two through slots 23, but less than the distance between the openings of the two through slots 23. Furthermore, the distance between the end of the limiting bolt 15 and the top wall of the mounting beam 12 is not less than the depth of the through slot 23, and the end diameter of the limiting bolt 15 is greater than the width of the through slot 23.

[0040] like Figures 1 to 4 As shown, the cable support 30 is detachably mounted on the servo frame 20. The cable support 30 has a slot 31 for the cable to pass through, and the slot 31 is located below the servo's adjustment lever.

[0041] In this embodiment, the slot 31 is funnel-shaped. Because the existing adjusting cable has a metal sheath on the outside, the funnel-shaped slot 31 makes it easy to place the adjusting cable into the slot 31, and at the same time, it can better limit and fix the adjusting cable at the wider part of the funnel opening.

[0042] In this embodiment, the cable frame 30 is L-shaped, and threaded holes 32 are provided on the vertical part of the cable frame 30 corresponding to the position of each fixing hole 27. Each threaded hole 32 is provided with a third fixing bolt 33.

[0043] The role and effect of the embodiments

[0044] According to the aviation unmanned aerial vehicle (UAV) engine throttle valve servo mounting bracket assembly involved in this utility model, by optimizing the bracket structure, the bracket structure is simple and compact, easy to assemble, and has high strength, thereby preventing the bracket from deforming during use. At the same time, because the bracket is arranged close to the engine throttle valve, it can reduce the cumulative control error of the throttle valve drive, and ensure the accuracy and consistency of the UAV engine throttle valve position control.

[0045] According to the aviation unmanned aerial vehicle engine throttle servo mounting bracket assembly involved in this utility model, because the inner walls of the positioning hole, mounting hole and fixing hole are all provided with threads, they can be directly threadedly connected to the first fixing bolt, the second fixing bolt and the third fixing bolt, thereby eliminating the need for fixing nut workpieces, and thus making the structure of this utility model simple.

[0046] According to the aviation unmanned aerial vehicle engine throttle servo mounting bracket assembly involved in this utility model, because the servo bracket is slidably mounted on the mounting base through two U-shaped through slots, the position of the servo bracket can be freely adjusted within the through slots.

[0047] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
