Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a flattening and positioning structure for plastic parts of an unmanned aerial vehicle. Background Technique

[0002] At present, in order to facilitate the manufacture of the fuselage main body parts of unmanned aerial vehicles, most of the fuselage main body parts of multi-axis unmanned aerial vehicle aircraft are made of plastic materials and integrally formed by injection molding, which can not only save the material cost, but also has a light, stable and firm overall structure.

[0003] In the prior art, arm sleeves are arranged inside the fuselage main body parts of unmanned aerial vehicles to facilitate the insertion and connection of the arms, and then multiple groups of bolt locking clamps are used to tightly fix and position the arms. However, this structure is troublesome to operate when locking, and the outer shape structure of the clamp is fixed, making it difficult to fit with arms of different shapes, resulting in insufficient firmness after clamping and the problem that the arms are prone to looseness and deflection.

[0004] Therefore, we propose a flattening and positioning structure for plastic parts of an unmanned aerial vehicle to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a flattening and positioning structure for plastic parts of an unmanned aerial vehicle to solve the problems raised in the above background technique.

The arm sleeve is arranged inside the fuselage main body part, and the movable clamp and the fixed clamp are installed inside the arm sleeve for clamping and positioning the arm. One end of the fixed clamp is connected with a guide rod, and the guide rod movably penetrates through one end of the movable clamp. The other end of the fixed clamp is installed with a stop piece, a screw rod is rotatably connected to the stop piece, and the screw rod is threadedly connected to the other end of the movable clamp. Profiled rubber pads are installed on the opposite surfaces of the movable clamp and the fixed clamp, and the profiled rubber pads are fitted to the outer shape of the arm.

[0008] In a further embodiment, a back plate is provided on the back of the fixed clamp, and one end of the arm extending into the arm sleeve is fitted to the back plate.

[0009] In a further embodiment, T-shaped grooves are formed on the opposite surfaces of the movable clamp and the fixed clamp, and T-shaped strips are provided on the back of the profiled rubber pads and are matingly clamped with the T-shaped grooves.

[0010] In a further embodiment, a positioning groove is formed in the middle of the T-shaped groove along the radial direction, and a positioning protrusion is provided in the middle of the T-shaped strip and is matingly clamped with the positioning groove.

[0011] In a further embodiment, a short rod is connected under the baffle, and a nut is screwed on one end of the short rod passing through the lower part of the fixed clamp.

[0012] In a further embodiment, the outer diameter of the baffle is smaller than the outer diameter of the screw rod, and the outer diameter of the baffle is larger than the outer diameter of the short rod.

[0013] In a further embodiment, embedding grooves are formed on the opposite surfaces of the movable clamp and the fixed clamp.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The present utility model can customize the shape of the profiling rubber pad according to different shapes of the machine arm. When the movable clamp and the fixed clamp are tightened, the profiling rubber pad fits more closely to the shape of the machine arm, thereby enhancing the firmness of the pressing and positioning of the machine arm, making it difficult for the machine arm to loosen and deflect. And only by rotating the screw rod, the movable clamp can be controlled to approach or move away from the fixed clamp, thereby realizing clamping or loosening of the machine arm, making the disassembly and assembly operation of the machine arm more convenient and labor-saving.

[0026] Please refer to Figures 1-3, A flattening and positioning structure for a plastic part of a drone, including a movable clamp 4 and a fixed clamp 5. The movable clamp 4 and the fixed clamp 5 are installed in the arm sleeve 3, and the arm sleeve 3 is installed in the fuselage main body 1. The bottom of the fixed clamp 5 is fixed to the bottom surface of the fuselage main body 1. The arm 2 passes through the arm sleeve 3 from outside the fuselage main body 1 and is clamped and positioned by the movable clamp 4 and the fixed clamp 5. One end of the fixed clamp 5 is connected with a guide rod 6, and the guide rod 6 movably penetrates through one end of the movable clamp 4. A stop piece 7 is installed at the other end of the fixed clamp 5. A screw rod 8 is rotatably connected to the stop piece 7, and the screw rod 8 is threadedly connected to the other end of the movable clamp 4. The screw rod 8 penetrates through the movable clamp 4. When the screw rod 8 is rotated, due to the thread action and the limiting action of the guide rod 6, the movable clamp 4 will not deflect but move closer to or away from the fixed clamp 5. Imitation rubber pads 9 are installed on the opposite surfaces of the movable clamp 4 and the fixed clamp 5. Considering the actual production and manufacturing process, the shape of the arm 2 may be designed into different shapes, such as circular, oval, irregular, etc. The shape of the imitation rubber pad 9 can be customized according to the shape of different arms 2, so that the imitation rubber pad 9 fits the shape of the arm 2 and the positioning is more firm.

[0027] Please refer to Figure 3 and Figure 5 , In order to facilitate the arm 2 to press against the entire positioning structure, a back plate 51 is provided on the back of the fixed clamp 5, and one end of the arm 2 extending into the arm sleeve 3 is attached to the back plate 51, so as to limit the end of the arm 2.

[0028] Please refer to Figures 5-6 , In order to facilitate the replacement of imitation rubber pads 9 of different shapes, T-shaped grooves 13 are provided on the opposite surfaces of the movable clamp 4 and the fixed clamp 5, and T-shaped strips 91 are provided on the back of the imitation rubber pad 9 and are matched and clamped with the T-shaped grooves 13. The T-shaped strips 91 can be inserted into the T-shaped grooves 13, so that the connection and disassembly are convenient.

[0029] Furthermore, a positioning groove 14 is radially provided in the middle of the T-shaped groove 13, and a positioning protrusion 92 is provided in the middle of the T-shaped strip 91 and is matched and clamped with the positioning groove 14.
