Abstract
Description
Technical Field

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0023] like Figure 1-2 As shown, a blade protection structure of a UAV includes a steering gear and a mounting seat 1 of the steering gear, an outer protective ring 2 is arranged on the mounting seat 1, and also includes a first plate 4 and a second plate 5 that are slidably assembled, and the first plate 4 and the second plate 5 are respectively provided with a lateral elastic member 3 at one end connected to the outer wall of the outer protective ring 2 at opposite ends;
[0024] A first plate member 4 and a second plate member 5 form a buffer group, and are arranged in a circular array about the outer protective ring member 2 .
[0025] Specifically, the mounting seat 1 is located at the axis of the outer protective ring 2, and the two are connected by a plurality of round rods arranged in a circumferential array, so that the mounting seat 1 is fixed. This is a conventional technology and will not be elaborated on.
[0026] Secondly, the lateral elastic member 3, the first plate member 4 and the second plate member 5 in the embodiment are all carbon fiber plates. Because the carbon fiber plates are relatively light and hard, they can be used in long-term collision environments.
[0027] In the above technology, multiple modular buffer groups arranged in a circumferential array are assembled on the outer anti-ring member 2 to provide a double protection effect. When a collision occurs, whether the first plate member 4 or the second plate member 5 is subjected to lateral or frontal force, the first plate member 4 and the second plate member 5 will shrink, and release the force and recover under the action of the lateral elastic member 3.
[0028] As an embodiment further provided by the present invention, the buffer group is divided into an upper buffer group and a lower buffer group along the axial direction of the outer anti-ring member 2, and a predetermined distance is maintained between the upper buffer group and the lower buffer group.
[0029] Specific, combined Figure 1 It can be known that the embodiment adopts the upper buffer group and the lower buffer group along the axial direction of the outer protective ring 2. The purpose is to make the first plate 4 and the second plate 5 be subjected to frontal force through the upper buffer group and the lower buffer group to divide the force, and the lateral force on the first plate 4 and the second plate 5 can also play a force dividing effect, thereby optimizing the buffering effect.
[0030] As another embodiment further provided by the present invention, the lateral elastic member 3 is in the shape of an oblique broken line and has at least two vertices, and both vertices are not in contact with the outer wall of the outer protective ring member 2 .
[0031] With respect to the horizontal plane, one end of the lateral elastic member 3 is at a high position, and the other end is at a low position, and the low position is connected to the outer protective ring member 2 .
[0032] Specifically, in the embodiment, when the first plate 4 and the second plate 5 are subjected to frontal force, during the deformation of the lateral elastic member 3, the two vertices may successively contact the outer protective ring member 2, thereby reducing the force applied to the first plate 4 and the second plate 5 to the outer protective ring member 2, thereby optimizing the buffering effect.
[0033] As another embodiment further provided by the utility model, the second plate 5 is provided with a notch 51 and further includes a U-shaped member 6, a first end of which is connected to the side wall of the first plate 4, and a second end of which is connected to an end of the first plate 4 opposite to the notch 51.
[0034] Furthermore, the bottom of the U-shaped member 6 extends out from the notch 51 and contacts the side wall of the outer protective ring member 2 .
[0035] Specifically, when the first plate member 4 or the second plate member 5 is subjected to force on either side, the U-shaped member 6 will also be squeezed and deformed, and at the same time, the force will be released and restored under the action of the lateral elastic member 3.
[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
