[0041] As Figure 1 and Figure 2 As shown, a drone with a throwing function provided by an embodiment of the present utility model includes a quad-rotor drone and a grenade throwing mechanism 4. The quad-rotor drone includes a fuselage 1 and four flight drive components connected to the fuselage 1. The flight drive component includes a support arm 2 and an electric rotor 3 provided at one end of the support arm 2. The grenade throwing mechanism 4 is arranged at the bottom of the fuselage 1.

[0042] The other end of the support arm 2 is foldably connected to the fuselage 1 through a folding component 5, enabling the support arm 2 to switch between a horizontally deployed state and a vertically retracted state. When the support arm 2 is in the vertically retracted state, the support arm 2 fits against the grenade throwing mechanism 4.

[0043] Specifically, as Figure 3 shown, the folding component 5 includes two relatively arranged support plates 6, a rotating member 8 rotatably installed between the two support plates 6 through a rotating shaft 7, and a limiting member arranged between the two support plates 6. The two support plates 6 are arranged longitudinally, and the bottom and top ends of the support plates 6 are fixedly installed on the fuselage 1 through screws.

[0044] As Figure 4As shown, the rotating member 8 includes a connecting portion 9 for connecting with the support arm 2 and a limiting portion 10 provided at the other end of the connecting portion 9. The connecting portion 9 can be a sleeve, and one end of the support arm 2 is directly inserted into the connecting portion 9 and fixed by screws to complete the assembly. The limiting portion 10 is plate-shaped, and the rotating shaft 7 rotates through the middle of the limiting portion 10. There is a limiting groove 11 on the top end face of the limiting portion 10 near the limiting member. The limiting groove 11 is of an L-shaped structure, and there is an arc-shaped transition surface 12 between the end of the limiting groove 11 close to the limiting member and the bottom end face of the limiting portion 10. The transition surface 12 is convexly provided.

[0045] The limiting member includes a limiting shaft 13 and an elastic member. There are horizontally extending movable holes 14 on the support plate 6. The limiting shaft 13 is arranged between the two movable holes 14, and both ends of the limiting shaft 13 extend out of the corresponding movable holes 14 and are movably arranged. The elastic member is connected to the limiting shaft 13, and the elastic force of the elastic member is perpendicular to the limiting shaft 13. The elastic force of the elastic member faces the rotating member 8, so that the limiting shaft 13 is always in contact with the limiting portion 10 under the action of the elastic force of the elastic member.

[0046] Among them, when the support arm 2 is in the horizontal unfolded state, the limiting shaft 13 is clamped in the limiting groove 11, and the limiting shaft 13 is in contact with the longitudinal side wall and the horizontal side wall of the limiting groove 11 to horizontally limit the support arm 2. When the support arm 2 is in the vertical storage state, the limiting shaft 13 abuts against the bottom end face of the limiting portion 10.

[0047] In this embodiment, the elastic member includes a horizontally arranged guide rod 15 and a spring 16 sleeved on the guide rod 15. One end of the guide rod 15 slidably passes through the middle of the limiting shaft 13. The guide rod 15 is perpendicular to the limiting shaft 13, and the limiting shaft 13 can slide axially along the guide rod 15. The other end of the guide rod 15 is fixedly provided with a fixing rod 17. The fixing rod 17 is perpendicular to the guide rod 15, and both ends of the fixing rod 17 are fixedly installed on the corresponding support plates 6. Both ends of the spring 16 respectively abut against the limiting shaft 13 and the fixing rod 17 to provide elastic force through the spring 16.

[0048] Moreover, end caps 18 are provided at both ends of the limiting shaft 13 outside the support plate 6. When it is necessary to fold and store the support arm 2, use a finger to pull the end cap 18 in the direction away from the support arm 2, so that the limiting shaft 13 moves in the movable hole 14 in the direction away from the support arm 2, and the limiting shaft 13 is separated from the limiting groove 11. Then, rotate the support arm 2 downward, and the limiting portion 10 will rotate upward around the rotating shaft 7 until the support arm 2 fits with the grenade throwing mechanism 4. Then, release the end cap 18 with the finger. Under the elastic force of the spring 16, the limiting shaft 13 is pushed to reset, so that the limiting shaft 13 abuts against the bottom end face of the limiting portion 10, and the support arm 2 will not move randomly.

[0049] When it is necessary to deploy the support arm 2, only need to pull up the support arm 2 upwards, the limiting part 10 will rotate downwards around the rotating shaft 7, squeeze the limiting shaft 13 through the transition surface 12 on the limiting part 10, and the limiting shaft 13 will move away from the support arm 2 along the movable hole 14 until the transition surface 12 rotates downwards to the end, and the limiting shaft 13 is re-engaged into the limiting groove 11 to horizontally deploy the support arm 2.

[0050] In this embodiment, as Figure 5 and Figure 6 shown, the grenade throwing mechanism 4 includes a longitudinally arranged storage cylinder 19, a downward pushing component 20 arranged at the top of the storage cylinder 19, and a grenade retaining ring 21 arranged at the bottom of the storage cylinder 19. The top end of the storage cylinder 19 and the downward pushing component 20 are both fixedly installed at the bottom of the fuselage 1. A loading hole 27 for loading grenades is arranged in the middle of the storage cylinder 19. The downward pushing component 20 pushes the grenades stored in the storage cylinder 19 downwards until the grenades fall out of the bottom of the storage cylinder 19 after breaking free from the restriction of the grenade retaining ring 21.

[0051] Specifically, the downward pushing component 20 includes an electric push rod 22 and a push plate 23 installed on the electric push rod 22. The top of the electric push rod 22 is fixedly installed at the bottom of the fuselage 1. The electric push rod 22 pushes the push plate 23 to move up and down along the storage cylinder 19.

[0052] The grenade retaining ring 21 includes an elastic cord 24 in the shape of a circular ring and a plurality of rolling balls 25 connected to the elastic cord 24. The elastic cord 24 is threaded through the rolling balls 25, and the rolling balls 25 can rotate around the elastic cord 24. A plurality of mounting holes 26 are evenly distributed along the circumference at the bottom of the barrel wall of the storage cylinder 19. The rolling balls 25 are arranged in one-to-one correspondence with the mounting holes 26. The elastic cord 24 is sleeved on the outer wall of the storage cylinder 19, and a part of the spherical surface of the rolling ball 25 passes through the mounting hole 26 and is arranged inside the storage cylinder 19.

[0053] When throwing a grenade, the electric push rod 22 pushes the push plate 23 to push the grenade stored in the storage cylinder 19 downwards. The grenade can fall down after squeezing through the grenade retaining ring 21. When the grenade squeezes through the grenade retaining ring 21, the rolling ball 25 will be extruded out of the mounting hole 26 by the grenade, but the rolling ball 25 will not completely break away from the mounting hole 26, so that the entire grenade retaining ring 21 will not be separated from the storage cylinder 19.

[0054] In summary, for the UAV with a throwing function provided by the present utility model, in the storage state, the support arm is attached to the grenade throwing mechanism, so that the volume can be reduced and it is more convenient to carry. Moreover, the grenade throwing mechanism is integrally cylindrical in shape with a compact structure. During the carrying process, the downward pushing component is not easily damaged by external objects, has strong protection, is more convenient to carry, and is more practical.

[0055] Finally, it should be noted that the technical features of the technical solution of the present application can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope recorded in the present application.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
