  The protection device 1 of the present embodiment includes a frame 100, a bumper 200, and a net 300, as shown in FIGS. As shown in FIG. 3 and the like, the frame 100 includes an upper plate 101, a lower plate 102, and a support 103, and holds the drone 500. The bumper 200 is a rod-like member provided so as to protrude in four directions from each of the upper plate 101 and the lower plate 102. The net 300 is a member that covers the entire drone 500. In FIGS. 1 to 8, the net 300 is held so as to cover an outer shell area where the drone 500 is held by the frame 100 and the tip end on the opposite side of the mounting end of the bumper 200 to the upper plate 101 and the lower plate 102 is a vertex. It shows the attached state. A substantially spherical cushion portion 210 is attached to the tip of the bumper 200.

  The drone 500 includes an upper panel 501 located below the upper plate 101 of the frame 100, a lower panel 502 located above the lower plate 102 of the frame 100, and four propellers 510 as propulsion units. As shown in FIGS. 7 and 8, the propellers 510 are positioned on the same two diagonal lines. The drone 500 is provided with an arm 520 for supporting the propeller 510, and between the upper panel 501 and the lower panel 502 is provided a precision instrument such as a camera or GPS.

1.2 Configuration of Net The net 300 is formed of a resin material such as aramid fiber. 7 with the cushion 210 of the protection device 1 at the top, the lower surface shown in FIG. 8, the front surface shown in FIG. 3, the back surface shown in FIG. 4, the left side shown in FIG.

By providing the net 300, when the drone 500 contacts or collides with an external thing, it is possible to prevent the external thing from being damaged by the propeller 510 or the like. Further, by providing the net 300, damage to the drone 500 such as the propeller 510 can also be prevented. Furthermore, by providing the net 300, the propeller 510 of the drone 500 can be prevented from hitting a person.

  Since the net 300 is formed of a reticulated resin material, it is lightweight and has low air resistance, and the impact on the flight performance of the drone 500 can be reduced.

1.3 Configuration of Frame FIGS. 9 to 16 are views corresponding to FIGS. 1 to 8 and are perspective views of the drone 500 and the protection device 1 of the drone 500 seen from the top in a state where the net 300 is removed, respectively.

Moreover, FIG.17 and FIG.18 leave the upper panel 501 and lower panel 502 of the drone 500 in each of FIG.9 and FIG. 11, The perspective view and the front view in the state which removed the other part of the drone 500. FIG.

  The frame 100 penetrates the upper plate 101 and the lower plate 102 sandwiching the drone 500 vertically and the upper panel 501 and the lower panel 502 of the drone 500 as shown in FIGS. , And a support 103 attached to the upper plate 101 and the lower plate 102. In the present embodiment, the number of columns 103 is two as an example, but the number of columns 103 may be further increased.

  In the present embodiment, the drone 500 and the frame 100 are connected via a cushioning material for shock absorption. Specifically, as shown in FIG. 18, between the upper panel 501 of the drone 500 and the upper plate 101 of the frame 100 and between the lower panel 502 of the drone 500 and the lower plate 102 of the frame 100, The cushion material 400 is disposed. Also, a cushioning material is disposed between the openings provided in the upper and lower panels 501 and 502 of the drone 500 and the columns 103 of the frame 100. Hereinafter, the cushion material provided between the support column 103 and the upper panel 501 and the lower panel 502 will be described.

  FIG. 19 is a cross-sectional view showing only the periphery of the column 103 in the cross section along line AA in FIG. FIG. 20 is a perspective view of only the support 103 taken out. As shown in FIG. 19, the column 103 has a small diameter pipe 130 having a length extending from the upper plate 101 to the lower plate 102 and a length corresponding to the distance from the upper panel 501 to the lower panel 502 of the drone 500. And a cylindrical support portion 131 which encloses the small diameter pipe 130. The small diameter pipe 130 is fitted to the support column 131 at a position that is the central axis in the longitudinal direction of the support column 131. The small diameter pipe 130 is formed of, for example, a metal material such as aluminum, and the column portion 131 is formed of, for example, a resin material or the like.

  In the upper panel 501 and the lower panel 502 of the drone 500, an opening having a diameter larger than the outer diameter of the support portion 131 is formed. Therefore, a gap is generated between the opening of the upper panel 501 and the lower panel 502 and the outer periphery of the support portion 131. In the present embodiment, as shown in FIG. 19 and FIG. A cushion material 401 is provided on the side surface of the portion 131 to cover the side surface of the support portion 131. For the cushion material 401, for example, an elastic material such as rubber or a resin material can be used. As described above, the support portion 131 is press-fit into the opening portions of the upper panel 501 and the lower panel 502 without a gap by the cushion material 401 covering the side surface of the support portion 131.

  The receiving portion 105 is attached to the lower surface of the upper plate 101 of the frame 100 and the upper surface of the lower plate 102, and both ends of the small diameter pipe 130 of the column 103 are fitted to the receiving portion 105. With such a structure, the drone 500 can be held by the upper plate 101, the lower plate 102 and the support 103 of the frame 100.

  As described above, in the present embodiment, the cushioning material 401 is provided between the support column 103 and the upper panel 501 and the lower panel 502 of the drone 500, and the upper panel 501 and the upper plate of the frame 100 are provided. A cushioning material 400 is provided between the space 101 and the lower panel 502 and the lower plate 102 of the frame 100. Therefore, even when the cushion portion 210 attached to the bumper 200 contacts the ground or the like when the drone 500 lands, or even when the protection device 1 contacts or collides with another object, The impact is not transmitted directly to the drone 500 but transmitted to the drone 500 via the cushioning members 400 and 401. As a result, even when the drone 500 lands or when the protection device 1 contacts or collides with another object, the impact force transmitted to the drone 500 is alleviated and damage to the drone 500 can be prevented.

1.4 Bumper Configuration The bumper 200 is provided at its tip with a cushion portion 210 for absorbing an impact. The cushion portion 210 in the present embodiment is, for example, formed in a spherical shape. The shape of the cushion portion 250 is not limited to a spherical shape, and may be another shape such as a heart shape, for example. As the cushion portion 210, an elastic material such as rubber or a resin material can be used. By providing the cushion portion 210, when the protection device 1 contacts or collides with another object, the cushion portion 210 first contacts or collides with the other object, thereby reducing the impact given to the other object. Other objects can be protected. In addition, since the cushion portion 210 is provided on the outer side of the propeller 510 of the drone 500, the propeller 510 can be prevented from coming into contact with a person even when the protection device 1 comes into contact with a person, damaging the person. Can be prevented.

  FIG. 21 shows only the periphery of the bumper 200. As shown in FIG. As shown in FIG. 21, the bumper 200 includes a buffer portion 220 in the middle of the attachment portion 221 to the upper plate 101 or the lower plate 102 and the tip portion 222. Buffer portion 220 in the present embodiment has a bellows structure as shown in FIG. 21 as an example. The structure of the buffer portion 220 is not limited to the bellows structure, and may be, for example, a spring structure. The connection 225 between the buffer 220 and the bumper 200 is thinner than the other parts of the bumper 200. When a large impact is applied to the bumper 200 due to a collision or the like between the cushion portion 210 and another object, stress concentrates on the connecting portion 225 due to the moment, and the bumper 200 is cut off by the buffer portion 220. It is configured. As described above, in the present embodiment, by providing the buffer portion 220 in the bumper 200, even when the cushion portion 210 collides with or contacts another object, the shock at that time is obtained by the buffer portion 220. Being absorbed, the drone 500 can be prevented from being damaged and the drone 500 can be protected.

  The bumper 200 is made of, for example, plastic (nylon, ABS, polycarbonate or the like), plastic with carbon (CRP), dry / wet carbon fiber or the like, and can be replaced. The bumper 200 is attached to the upper plate 101 and the lower plate 102 of the frame 100, and the upper plate 101 and the lower plate 102 are attached to the upper panel 501 and the lower panel 502 of the drone 500 via the cushioning material 400 as described above. . Thus, in the present embodiment, the bumper 200 is provided on the upper plate 101 and the lower plate 102 different from the support of the propeller 510 of the drone 500. Therefore, even if the cushion portion 210 collides with or contacts another object, the impact at that time can be prevented from being directly transmitted to the drone 500, and the drone 500 can be protected.

  22 and 23 are diagrams for explaining the state when the cushion portion 210 contacts an object on the ground or the outside. When the cushion portion 210 contacts the ground or an external object in the direction as shown in FIG. 23, the attachment portion 221 of the bumper 200 in the vertical direction to the upper plate 101 or the lower plate 102 of the frame 100 becomes the tip. The length and angle of the bumper 200 are set such that the distance D1 to the point of contact with the ground or external object of the cushion portion 210 is larger than the distance D2 from the attachment portion 221 to the outermost edge in the vertical direction of the drone 500. ing. In addition, the bumper 200 is provided at a position not to interfere with the propeller 510 of the drone 500. In this case, the outermost edge of the drone 500 in the vertical direction is an end of the support portion 530 of the drone 500.

  Further, when the cushion portion 210 contacts the ground or an external object in the direction as shown in FIG. 23, the attachment portion 221 of the bumper 200 in the horizontal direction with respect to the upper plate 101 or the lower plate 102 of the frame 100 The length and angle of the bumper 200 are such that the distance D3 to the contact point with the ground or external object of the cushion portion 210 becomes larger than the distance D4 from the attachment portion 221 to the outermost edge in the horizontal direction of the drone 500. It is set. In addition, the bumper 200 is provided at a position not to interfere with the propeller 510 of the drone 500. In this case, the outermost edge of the drone 500 in the horizontal direction is the end of the propeller 510 of the drone 500.

  In the present embodiment, as described above, the distances D1 and D2 from the attachment portion 221 of the bumper 200 in the vertical direction and the horizontal direction to the upper plate 101 or the lower plate 102 of the frame 100 are The length and angle of the bumper 200 are set to be larger than the distances D3 and D4 from the mounting portion 221 to the outermost edge in the vertical direction and the horizontal direction of the drone 500.

  Therefore, regardless of the angle at which the protection device 1 contacts the ground or an external object, the cushion portion 210 attached to the tip end portion 222 of the bumper 200 contacts the ground or external object, as described above. Due to the bumper 200 whose length and angle are set, the propeller 510 of the drone 500 and the like do not contact the ground or other objects. As a result, damage to the drone 500 can be prevented.

  Four bumpers 200 are provided on the upper plate 101 and the lower plate 102 of the frame 100. The direction of the bumper 200 is set in the same direction as the arm 520 supporting the propeller 510, as shown by arrow B in FIG. By setting the mounting direction of the bumper 200 in this manner, the length of the bumper 200 can be shortened and the weight can be reduced while minimizing the number of the bumpers 200.

  For example, when three bumpers 200 are provided on the upper plate 101 and the lower plate 102 of the frame 100, in order to realize the length and angle that can protect the drone 500 as described above, the apex of the bumper 200 Because of the small number, the length of the bumper 200 needs to be longer than in the present embodiment. As a result, the overall weight of the protection device 1 is increased. However, in the present embodiment, by setting the mounting direction of the bumper 200 to be the same as the direction of the arm 520 supporting the propeller 510, the weight of the protection device 1 can be reduced.

2. Operation Next, the operation of the protection device 1 in the present embodiment will be described. When flying the drone 500, the propeller 510 is to be rotated, but the bumper 200 is provided at a position not interfering with the propeller 510 as described above, and the net 300 is formed in a mesh shape . Accordingly, the propeller 510 rotates without being interfered by the bumper 200, and the drone 500 can fly with low air resistance.

  At the time of landing of the drone 500, or if the drone 500 loses control due to any reason, the cushion portion 210 attached to the tip portion 222 of the bumper 200 may be attached to the ground or another object or person. It will contact. However, the cushion portion 210 relieves the impact force transmitted to the bumper 200 by its elastic force. Furthermore, the net 300 forms an outer shell of the drone 500 covering the whole of the drone 500 and does not bring the propeller 510 of the drone 500 into contact with a person.

  In addition, since the bumper 200 is set to the length and angle as described above, the propeller 510 or the like of the drone 500 can be directly connected to another object or the like even in the case of landing or contact or collision of another object or the like. Do not touch. Furthermore, since the bumper 200 is attached to the upper plate 101 and the lower plate 102 of the frame 100 which are members different from the props of the propeller 510 of the drone 500, the impact force applied to the bumper 200 is directly applied to the drone 500. I can not tell you. Further, the cushioning material 400 provided between the upper plate 101 and the lower plate 102 of the frame 100 and the upper panel 501 and the lower panel 502 of the drone 500 reduces the impact force transmitted to the drone 500. Similarly, cushioning materials 401 provided between the support columns 103 of the frame 100 and the upper and lower panels 501 and 502 of the drone 500 reduce the impact force transmitted to the drone 500.

  Even if a relatively strong impact force is applied to the bumper 200, the buffer portion 220 provided between the tip end portion 222 of the bumper 200 and the attachment portion 221 is broken at the connection portion 225, and the impact is strong The force does not convey to the drone 500.

3. Effect etc. The protection device 1 of the present disclosure includes a frame 100 for holding the drone 500, a rod-like bumper 200 attached to the frame 100, and a net 300 attached to the bumper 200 and covering the entire drone 500. As a result, without providing a mechanism for operating the air bag or the like, it is possible to prevent damage to the drone 500 upon landing or collision and to prevent other objects or people from being injured with a simple configuration. Specifically, when the bumper 200 contacts or collides with an external object, the propeller 510 and the arm 520 which are part of the drone 500 are prevented from contacting or colliding with the external object. As a result, it is possible to prevent damage to the propeller 510, the arm 520 and the like which are part of the drone 500. In addition, when the bumper 200 collides with an external object and a large impact force is applied to the bumper 200, the cushion portion 210 and the buffer portion 220 of the bumper 200 and the cushion material absorb the impact on the drone 500. Ru. As a result, even when the drone 500 is mounted with a precision machine such as a camera, damage to the precision machine such as a camera can be prevented. Furthermore, since the entire drone 500 is covered by the net 300, the propeller 510 of the drone 500 can be prevented from contacting the human body.

  The frame 100 of the present disclosure includes an upper plate 101 and a lower plate 102 sandwiching the drone 500 at the upper and lower sides, and a support column 103 connecting the upper plate 101 and the lower plate 102. Thereby, it is possible to prevent direct application of impact force received by the protection device 1 to the drone 500, and damage to the drone 500 can be prevented.

  The bumper 200 of the present disclosure includes a cushion portion 210 provided at the tip end, and a buffer portion 220 provided between the attachment portion 221 to the frame 100 and the tip end 222. As a result, even if a strong impact force is applied to the bumper 200, the buffer portion 220 can be broken at the connection portion 225 to prevent the strong impact force from being directly applied to the drone 500. Damage can be prevented.

  In the bumper 200 of the present disclosure, the distance from the attachment portion 221 of the bumper 200 to the tip 22 in the vertical and horizontal directions with respect to the upper plate 101 and the lower plate 102 of the frame 100 is the vertical direction of the drone 500 from the attachment portion 221. Larger than the distance to the outermost edge in the horizontal direction. Therefore, it is possible to prevent the drone 500 from coming into direct contact or collision with the ground or other object regardless of the posture of the protection device 1 in contact or collision with the ground or other object.

  The four bumpers 200 of the present disclosure are provided in each of the upper plate 101 and the lower plate 102 and have the same direction as the arm 520 supporting the propeller 510 of the drone 500. As a result, the number of the bumpers 200 can be minimized, and the length of the bumpers 200 can be shortened, so that the weight of the protection device 1 can be reduced.

  The drone 500 of the present disclosure and the frame 100 are connected via a cushioning material. Thus, it is possible to protect the drone 500 without directly transmitting the impact force applied to the frame 100 through the bumper 200 to the drone 500.
