Referring to fig. 1 to 3, an embodiment of the present utility model provides a flight control device, which includes a housing 1, a connector, at least two printed circuit boards 2, and at least two fixing mechanisms 3. The connector employs an inter-board connector that can be used for interconnection between the printed circuit boards 2. A schematic structure of a fixing mechanism 3 is illustrated in fig. 1.

As shown in fig. 1, at least two printed circuit boards 2 are arranged in parallel in a stacked manner, and adjacent two printed circuit boards 2 are connected by a connector. At least two fixing mechanisms 3 are provided at circumferentially different positions of the printed circuit board 2. The fixing mechanism 3 includes a fixing lever 31 and a fixing assembly 32. The fixing bar 31 is perpendicular to the surface of the printed circuit board 2. The number of the fixing members 32 is identical to that of the printed circuit boards 2, and one end of each fixing member 32 is fixed to the fixing lever 31 and the other end is used to clamp and fix one printed circuit board 2, respectively. The printed circuit board 2 is fixed by clamping and fixing the printed circuit board 2 by the fixing assembly 32 without damaging the printed circuit board 2. Fig. 1 shows a schematic structure of two printed circuit boards 2 with two fixing assemblies 32. The connector, at least two printed circuit boards 2 and at least two fixing mechanisms 3 are all arranged in the shell 1, and the bottom ends of the fixing rods 31 are fixed with the bottom surface of the shell 1.

According to the flight control device provided by the embodiment of the utility model, at least two printed circuit boards 2 are stacked in parallel, and the adjacent two printed circuit boards 2 are connected by the connector, so that the electrical connection between the printed circuit boards 2 can be realized. The at least two fixing mechanisms 3 are arranged at circumferentially different positions of the printed circuit board 2, and the fixing components 32 of the fixing mechanisms 3 can clamp and fix one printed circuit board 2, so that the at least two printed circuit boards 2 can be stably fixed at intervals without damaging the printed circuit board 2. The bottom end of the fixing rod 31 of the fixing mechanism 3 is fixed to the bottom surface of the housing 1, so that the printed circuit board 2 can be fixed to the inner cavity of the housing 1, and the printed circuit board 2 is indirectly fixed to the housing 1 through the fixing rod 31 without damaging the printed circuit board 2. The arrangement mode of the at least two printed circuit boards 2 stacked in parallel greatly reduces the space occupied by the printed circuit boards 2, thereby reducing the space occupied by the flight control device.

As shown in fig. 2, the fixing assembly 32 includes a fastening portion 321, two clamping pieces 322, and two rubber bushings 323. The fastening portion 321 is fixed to the fixing lever 31. Two clamping pieces 322 are matched and arranged, and one end of each clamping piece is inserted and fixed in the fastening part 321. The two rubber sleeves 323 are respectively sleeved at the outer part of the fastening part 321 of one clamping piece 322. The clamping piece 322 is generally made of a thinner stainless steel sheet, so that the clamping piece can have certain elastic deformation, and can provide better clamping force when the two clamping pieces 322 are matched. The fixing component 32 of the embodiment of the application has a simple structure and is easy to realize, and meanwhile, due to the arrangement of the rubber sleeve 323, the damage to the printed circuit board 2 can be reduced.

With continued reference to fig. 2, the fastening portion 321 includes a fixing block 3211 and a mounting block 3212, and the fixing mechanism 3 further includes a bolt and a nut. One end face of the fixing block 3211 is integrally connected to one end face of the mounting block 3212. One end of each clamping piece 322 is inserted and fixed in the mounting block 3212. The fixing rod 31 is provided with a groove extending along the axial direction, a plurality of through holes 311 are arranged on each side wall of the groove at equal intervals along the axial direction of the fixing rod 31, and the positions of the through holes 311 on the two side walls are uniform and correspond to each other. The fixed block 3211 is disposed in the groove and can slide along the groove, and a via hole is disposed thereon. Bolts are inserted into corresponding through holes 311 on two side walls of the fixed rod 31 and through holes on the fixed block 3211, and nuts are sleeved at the front ends of the bolts.

Because a plurality of through holes 311 are formed in each side wall of the groove at equal intervals, the fixing blocks 3211 of the fastening part 321 are arranged in the groove and can slide along the groove, so that the installation position of the fixing assembly 32 can be adjusted, and the position of the fixing assembly 32 can be better adapted to the fixed interval between two adjacent printed circuit boards 2. The fixing assembly 32 and the fixing rod 31 are fixed by bolts and nuts, so that the fixing assembly 32 can be firmly fixed on the fixing rod 31.

As shown in fig. 2, the holding piece 322 includes a first sub-lateral piece 3221, a circular arc sub-piece 3222, and a second sub-lateral piece 3223 connected in sequence. The first sub-lateral piece 3221 is inserted and fixed to the fastening portion 321. The circular arc sub-sheet 3222 and the second sub-cross-sheet 3223 are sleeved with a rubber sleeve 323.

When the two clamping pieces 322 clamp and fix the printed circuit board 2, stress concentration and damage are likely to occur at the edge position of the printed circuit board 2. And when the two clamping pieces 322 clamp and fix the printed circuit board 2, the edge position of the printed circuit board 2 is positioned at the position of the arc sub-piece 3222, so that the edge position of the printed circuit board 2 can be prevented from being damaged when the printed circuit board 2 is clamped and fixed. Of course, in order to make the clamping force of the fixing component 32 better, as shown in fig. 2, the thickness of the rubber sleeve 323 corresponding to the concave in the circular arc sub-piece 3222 is thicker, so that the fixing component 32 can maintain better clamping force, and the edge position of the printed circuit board 2 can be ensured not to be damaged.

Referring to fig. 1 and 2, the fixing mechanism 3 further includes a cylindrical seat 33. The top surface of the cylinder seat 33 is fixed to the bottom end of the fixing rod 31. The cylindrical seat 33 is fixed to the bottom surface of the housing 1. The cylindrical seat 33 is provided to make the fixing rod 31 more stable, and the fixing area of the fixing mechanism 3 for fixing with the bottom surface of the housing 1 is larger, which is more convenient for fixing.

As shown in fig. 2, the fixing mechanism 3 further includes a clamping structure 34. The clamping structure 34 includes a sleeve 341, a limiting member 342, and an operating end 343. The sleeve 341 is sleeved on the upper end of the fixed rod 31. The sleeve 341 facilitates the fixing of the clamping structure 34 to the fixing rod 31. The lower end of the limiting member 342 is integrally connected with the upper end surface of the sleeve 341, and the upper end is connected with the lower end of the operation end 343. The stopper 342 protrudes outward of the sleeve 341. A limit groove matched with the limit piece 342 is arranged on the inner side wall of the shell 1.

In practice, at least two printed circuit boards 2 arranged in parallel stacked are fixed to the bottom surface of the housing 1 by the fixing mechanism 3, but the printed circuit boards 2 have the possibility of rattling in the inner cavity of the housing 1. The arrangement of the clamping structure 34 can enable the upper portion of the fixing mechanism 3 to be restrained, and at least two printed circuit boards 2 are not easy to shake in the inner cavity of the shell 1 in the flight process of the unmanned aerial vehicle. Specifically, after the lower end of the fixing mechanism 3 is fixed to the bottom surface of the housing 1, the clamping structure 34 is deformed by pressing the operation end 343, and then the clamping structure 34 is released when the limiting member 342 is aligned to the limiting groove, so that the limiting member 342 of the clamping structure 34 is clamped into the limiting groove. When the printed circuit board 2 needs to be disassembled, the clamping structure 34 is deformed by pressing the operation end 343, and the limiting member 342 is withdrawn from the limiting groove.

Further, as shown in fig. 2, the limiting member 342 includes a first horizontal section 3421, a first inclined section 3422, a second inclined section 3423, and a second horizontal section 3424, which are sequentially connected. The first horizontal section 3421 and the second horizontal section 3424 are each parallel to the bottom surface of the housing 1. When the limiting piece 342 is clamped into the limiting groove, the first horizontal section 3421 is attached to the upper wall of the limiting groove, and the second horizontal section 3424 is attached to the lower wall of the limiting groove, so that the first horizontal section 3421 and the second horizontal section 3424 limit the movement of the fixing mechanism 3 in the height direction. The limit groove is internally provided with a triangular protrusion which is matched with the first inclined section 3422 and the second inclined section 3423, and when the limit piece 342 extends into the limit groove, the triangular protrusion plays a role in guiding the limit piece 342. The two side surfaces of the limiting piece 342, which are parallel to the direction extending into the limiting groove, are attached to the two side surfaces of the limiting groove, so that the fixing mechanism 3 is limited to move in the horizontal direction.

The transition fillets are arranged between the first horizontal section 3421 and the first inclined section 3422 and between the second inclined section 3423 and the second horizontal section 3424, so that the inner wall of the shell 1 can be prevented from being scratched by the fixing mechanism 3 in the mounting and dismounting processes.

Alternatively, the housing 1 is made of an aluminum material. The density of the aluminum alloy material is smaller, and the weight of the product can be reduced.

The utility model further provides an unmanned aerial vehicle, which comprises the flight control device, wherein the flight control device occupies small space of the unmanned aerial vehicle.

In this specification, each embodiment is described in a progressive manner, and the same or similar parts of each embodiment are referred to each other, and each embodiment is mainly described as a difference from other embodiments.

The above embodiments are only for illustrating the technical solution of the present application, and not for limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced with equivalents; such modifications and substitutions do not depart from the spirit of the corresponding technical solutions.
