Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) equipment technology, specifically to a UAV generator starter engine. Background Technology

[0002] A drone is an unmanned aerial vehicle that can be operated via remote control or a pre-programmed flight path without the need for a human to ride in it. There are various types of drones, including consumer drones used for aerial photography, which can capture high-quality photos and videos.

[0003] Drones typically consist of a fuselage, power system, flight control system, communication system, and onboard equipment. As technology advances, the performance of drones continues to improve, with the power system being the primary source of power.

[0004] Most existing engines use gear transmission. While gear transmission is compact, wear and tear can occur after the gears mesh together during prolonged use, leading to reduced transmission efficiency and affecting the transmission effect.

[0005] Therefore, in response to the above problems, a method for starting the engine of an unmanned aerial vehicle (UAV) is proposed. Utility Model Content

At the same time, the arc-shaped design of the fixed plate and the baffle can reduce frictional resistance when in contact, thereby reducing the impact on the rotation of the round rod, so that the driving wheel and the driven wheel are lubricated by the tapping of the fixed plate when the round rod rotates, thereby maintaining the driving wheel and the driven wheel.

[0008] Preferably, a plurality of damping springs are fixedly connected inside the base; a placement plate is fixedly connected to the top of the damping springs; by adding damping springs, the swaying generated when driving the propeller to rotate can be absorbed, thereby increasing the stability on the base surface and thus reducing the swaying of the outer shell.

[0009] Preferably, the outer shell is porous; fins are fixedly attached to the surface of the engine body; multiple fins are arranged on the engine body; by adding fins, the heat inside the engine body can be quickly dissipated through the fins, thereby reducing the temperature inside the engine body.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, the UAV avionics generator starter includes a base 1, with a housing 11 on the top of the base 1; an engine body 12 is disposed inside the housing 11; a square plate 13 is fixedly connected inside the engine body 12; a motor 14 is fixedly connected to the side wall of the square plate 13; a round rod 15 is fixedly connected to the output end of the motor 14; the round rod 15 is through-hole and rotatably connected to the square plate 13; a drive wheel 16 is fixedly connected to the end of the round rod 15; the drive wheel 16 and the engine body 12 are rotatably connected; a driven wheel 17 is rotatably connected to the inner wall of the engine body 12; the driven wheel 17 is rotatably connected to the inner wall of the engine body 12; the driven wheel 16 is rotatably connected to the side ... Wheel 17 and drive wheel 16 are correspondingly arranged and drive-connected; a rotating shaft 18 is fixedly connected to the side wall of the driven wheel 17; the rotating shaft 18 is through-connected and rotatably connected to the engine body 12 and the housing 11; a fixing plate 19 is fixedly connected to the middle of the round rod 15; the end of the fixing plate 19 is arc-shaped; an oil box 101 is fixedly connected inside the engine body 12; a sliding plate 102 is slidably connected inside the oil box 101; a push rod 103 is fixedly connected to the bottom of the sliding plate 102; the push rod 103 is through-connected and slidably connected to the oil box 101; a baffle 105 is fixedly connected to the bottom of the push rod 103; the baffle 105 is arc-shaped; a compression spring 104 is fixed between the baffle 105 and the oil box 101; the bottom of the oil box 101 has multiple round holes 106; the round holes 106 are located between the drive wheel 16 and the driven wheel 17; during operation, the outer shell 11 is first placed on the surface of the base 1, and then the engine body 12 is installed inside the outer shell 11. Then, the motor 14 is started, causing the round rod 15 to drive the drive wheel 16 to rotate. When the drive wheel 16 rotates, it will push the driven wheel 17 to rotate. At this time, the propeller connected to the shaft 18 will rotate. When the round rod 15 rotates, the fixed plate 19 will rotate accordingly. When 9 rotates, the end will collide with the baffle 105. When the baffle 105 is impacted, it will move upward, thereby pushing the push rod 103 to move. When the push rod 103 is pushed, it will lift the slide plate 102. When the slide plate 102 leaves the round hole 106, the oil inside the oil box 101 will drip into the connection between the driving wheel 16 and the driven wheel 17 through the round hole 106. Then the slide plate 102 will return to its original state due to the pushing force applied by the compression spring 104 to the baffle 105, thereby closing the round hole 106. When the next impact occurs, the round hole 106 will open again to drip the oil, thereby lubricating the driving wheel 16 and the driven wheel 17.By adding a fixing plate 19 and an oil box 101, oil can be transferred to the connection point by the rotation of the round rod 15 when the driving wheel 16 and driven wheel 17 are used for transmission, thereby lubricating during transmission. This reduces friction upon contact, thus extending service life. Simultaneously, the arc-shaped design of the fixing plate 19 and the baffle 105 reduces frictional resistance upon contact, thereby minimizing the impact on the rotation of the round rod 15. Furthermore, the tapping action of the fixing plate 19 during the rotation of the round rod 15 lubricates the driving wheel 16 and driven wheel 17, thus maintaining their operation.

[0026] like Figure 2 As shown, multiple damping springs 2 are fixedly connected inside the base 1; a placement plate 21 is fixedly connected to the top of the damping springs 2; during operation, after the outer shell 11 is placed on the surface of the base 1, the engine body 12 is started to drive the propeller to rotate, which will generate vibration. At this time, the vibration will be transmitted to the damping springs 2 through the placement plate 21, and then the damping springs 2 will absorb these vibrations, thereby reducing the overall shaking and increasing the overall stability during operation; by adding damping springs 2, the shaking generated when driving the propeller to rotate can be absorbed, thereby increasing the stability on the surface of the base 1, thereby reducing the shaking of the outer shell 11.

[0027] like Figure 4 As shown, the outer shell 11 is porous; fins 3 are fixed to the surface of the engine body 12; multiple fins 3 are arranged on the engine body 12; during operation, the driving wheel 16 and the driven wheel 17 transfer heat to the surroundings. At this time, the heat inside the engine body 12 is dispersed to the outside through the fins 3, thereby dispersing the heat and reducing the hot air inside the engine body 12; by adding fins 3, the heat inside the engine body 12 can be quickly eliminated through the fins 3, thereby reducing the temperature inside the engine body 12.

[0028] like Figure 5 As shown, a telescopic rod 4 is fixedly connected to the top of the oil box 101; the end of the telescopic rod 4 is fixedly connected to the slide plate 102; during operation, the telescopic rod 4 will extend and retract synchronously when the slide plate 102 moves, thereby increasing the stability of the slide plate 102 when it moves, and increasing the support when the slide plate 102 moves; by adding the telescopic rod 4, the slide plate 102 can be more stable when it moves, so that the slide plate 102 maintains vertical movement and reduces shaking.

[0029] like Figure 5As shown, a counterweight 5 is fixedly connected to the top of the slide plate 102; multiple counterweights 5 are arranged on the slide plate 102; during operation, after the fixed plate 19 pushes the baffle 105, the slide plate 102 will fall due to the extension of the compression spring 104. At this time, the counterweight 5 increases the weight of the slide plate 102, thereby cooperating with the compression spring 104 to quickly restore the slide plate 102 and close the round hole 106; by adding the counterweight 5, the weight of the slide plate 102 can be increased, which makes the speed of the slide plate 102 moving down faster, thereby speeding up the closing of the round hole 106.

[0030] like Figure 4 As shown, a rubber pad 6 is fixed to the surface of the engine body 12; the rubber pad 6 is located at the bottom of the engine body 12; during operation, when the engine body 12 is placed inside the housing 11, the rubber pad 6 will first contact the housing 11, and then the rubber pad 6 will deform to buffer the impact when the engine body 12 falls; by adding the rubber pad 6, protection can be increased when placing the engine body 12, thereby reducing impact damage.

[0031] Working principle: First, place the outer casing 11 onto the surface of the base 1, then install the engine body 12 inside the outer casing 11. Then, start the motor 14, causing the rod 15 to drive the drive wheel 16 to rotate. When the drive wheel 16 rotates, it pushes the driven wheel 17 to rotate. At this time, the propeller connected to the shaft 18 will rotate. When the rod 15 rotates, the fixed plate 19 will rotate accordingly. When the fixed plate 19 rotates, its end will collide with the baffle 105. When the baffle 105 is impacted, it moves upward, thereby pushing the push rod 103 to move. When the push rod 103 is pushed, it will lift the slide plate 102. When the slide plate 102 leaves the round hole 106, the oil inside the oil box 101 will drip into the connection between the drive wheel 16 and the driven wheel 17 through the round hole 106. Then, the slide plate 102 will return to its original position due to the pushing force exerted by the compression spring 104 on the baffle 105, thus closing the round hole 106. When the next impact occurs, the round hole 106 will open again to drip oil, thereby lubricating the drive wheel 16 and the driven wheel 17. After the outer casing 11 is placed on the surface of the base 1, the engine body 1 is placed on the base 1. When the engine starts and drives the propeller to rotate, it will generate vibration. This vibration will be transmitted to the damping spring 2 through the placement plate 21. The damping spring 2 will absorb these vibrations, thereby reducing the overall shaking and increasing the overall stability during operation. When the drive wheel 16 and the driven wheel 17 are working, they will transfer heat to the surroundings. At this time, the heat inside the engine body 12 will be dispersed to the outside through the fins 3, thereby dispersing the heat and reducing the amount of hot air inside the engine body 12. When the slide plate 102 moves, the telescopic rod 4 will extend and retract synchronously, thereby increasing the stability of the slide plate 102 during movement and providing more support. After the fixed plate 19 pushes the baffle 105, the slide plate 102 will fall due to the extension of the compression spring 104. At this time, the counterweight 5 will increase the weight of the slide plate 102, thereby quickly restoring the slide plate 102 in conjunction with the compression spring 104 and closing the round hole 106. When the engine body 12 is placed inside the outer casing 11, the rubber pad 6 will first contact the outer casing 11, and then the rubber pad 6 will deform to buffer the impact when the engine body 12 falls.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
