The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

Example 1:

the present embodiment provides a drone, see the figure, comprising a body comprising a fuselage 100, an arm 100 and a motor mount 400, the drone in the present embodiment, preferably a mapping drone, the arms comprise two main arms 200, each main arm 200 is connected with two branch arms 300 through a tee joint, the two main arms 200 are oppositely connected to two sides of the machine body 100 and are coaxial, the two branch arms on the same side are coaxial, the end parts of the two branch arms are fixed with the motor base, the surveying and mapping unmanned aerial vehicle provided by the embodiment is a four-rotor unmanned aerial vehicle, this unmanned aerial vehicle still includes foldable foot rest 500, foldable foot rest 500 is fixed on the motor cabinet 400, specifically, the motor cabinet bottom on four horn is fixed with this foldable foot rest respectively, and four foldable foot rests are vertical connection respectively in corresponding motor cabinet bottom, and when unmanned aerial vehicle landed, foldable foot rest was used for supporting whole organism.

The foldable foot rest that this embodiment provided includes fixed joint 1, connector 2 and supporting leg 3, connector 2 with supporting leg 3 is connected, fixed joint 1's one end fixed connection be in on the organism, the other end with connector 2 rotates and connects, 3 framves of supporting legs pass through connector 2 is relative fixed joint 1 rotates, be equipped with two at least spacing grooves 2.3 on the connector 2, be equipped with on the fixed joint 1 with the corresponding spacing portion of spacing groove 2.3, when supporting leg 3 is under different states, corresponding spacing inslot is gone into to spacing portion correspondence card. Each limit groove corresponds to one state of the support foot rest, for example, when the support foot rest 3 is positioned in a vertical state, the limit part is correspondingly clamped into one limit groove 2.3 on the connector, and when the support foot rest is folded by a certain angle relative to the fixed connector, the limit part is clamped into the other corresponding limit groove, so that the support foot rest can be kept in a corresponding state.

The foot rest that this embodiment provided includes fixed joint, connector and support foot rest, if one of them part damages, can directly change, need not to change whole foot rest, is favorable to saving cost of maintenance.

Example 2:

on the basis of the embodiment 1, in this embodiment, preferably, the connector 2 is opened up and down and is hollow inside, the connector 2 includes a first connection portion 2.1 and a second connection portion 2.2 integrally connected up and down, and one end of the fixed joint 1 extends into the first connection portion 2.1 and is rotatably connected with the first connection portion. The fixed joint 1 is connected with the connector through a rotating pin 4, and two ends of the rotating pin 4 are connected to the connector 2. The second connecting portion 2.2 with 3 threaded connection of supporting foot rest, second connecting portion 2.2 is equipped with the external screw thread, the supporting foot rest is equipped with the internal thread.

The fixed joint 2 comprises a fixed seat 1.1, two connecting lug pieces 1.3 extend downwards from the lower part of the fixed seat 1.1, and the two connecting lug pieces extend into the first connecting part 2.1 of the connector and are rotatably connected onto a rotating pin 4. Two fixed columns 1.2 extend upwards on the upper portion of fixing base 1.1, fixing base 1.1 is connected with unmanned aerial vehicle's organism through the connecting piece that passes it, specifically, is connected with the motor cabinet on the unmanned aerial vehicle horn, and the connecting piece can be bolt and nut, and the motor cabinet includes base 401 and grafting pipe 402, and grafting pipe 402 an organic whole is connected on base 401, grafting pipe 402 is used for the one end of grafting horn, and downwardly extending has two parallel connecting blocks 403 on the pipe wall of the pipe of pegging graft, forms the accommodation space between two connecting blocks, and two fixed columns on the fixing base insert in the accommodation space, and the bolt passes through nut locking behind connecting block and the fixed column in proper order.

The first connecting portion are tubular, the pipe wall one side of first connecting portion is equipped with from top to bottom and sets up dodges breach 2.4, the rotating pin is horizontal dodge the breach inboard, should dodge the breach and can make two connection lug pieces pass through jointly when the supporting leg rotates, the both ends of rotating pin are connected on the inboard pipe wall of the breach of dodging of first connecting portion, the connector pass through the rotating pin to dodge the opposite side rotation of breach.

Because the supporting leg frame 3 is realized folding by the user after rotating to the opposite side of dodging breach place direction, if under the external force collision, the supporting leg frame also appears folding easily to lead to the unmanned aerial vehicle organism to empty, in order to overcome this defect, adopted following technical scheme in this embodiment: when the supporting foot stand is in an unfolded state, namely the folding foot stand is not provided, and when the foot stand is used for supporting the unmanned aerial vehicle body, the central line of the supporting foot stand inclines for 5-15 degrees to one side of the avoidance notch relative to the vertical direction. In this embodiment, it is preferred, slope 10 degrees, through with the supporting leg to dodging breach place one side slope, from this, be in under the state of supporting the unmanned aerial vehicle organism at the foot rest, if the supporting leg is collided to external force, the weight that needs overcome the whole organism of unmanned aerial vehicle could be folded the supporting leg, required this external force is great, general external force mistake collision is difficult to fold the supporting leg, thereby can guarantee the supporting role that the foot rest stabilizes, on the other hand, it is folding with restriction supporting leg mistake also to have saved the hasp structure.

Preferably, the limiting part is formed at the bottom of the connecting lug plate, and the limiting part is pointed

And (4) a bulge 1.4. The pipe walls on two sides of the avoidance notch are respectively provided with two limiting grooves which comprise a first limiting groove and a second limiting groove, and the two limiting grooves form an included angle of 95-105 degrees relative to the axis of the rotating pin, namely, an angle of 90+ external hectare of the supporting foot rest (for example, if the external hectare is 5 degrees, the included angle is 95 degrees).

In this embodiment, an angle of 100 degrees is preferred. The positions of the two limiting grooves respectively correspond to a supporting state (the supporting foot stand deviates from the vertical direction by a certain angle) and a horizontal state of the supporting foot stand, namely when the supporting foot stand is in the supporting state, the bottom of the pointed protrusion is clamped into the corresponding first limiting groove, when the supporting foot stand is folded towards the other side of the avoiding gap, the supporting foot stand drives the rotating pin 4 to rotate through the connector, and when the supporting foot stand is folded to the horizontal state, the supporting foot stand is correspondingly clamped into the second limiting groove. The foot rest is convenient and quick to fold, simple in fixing mode after being folded and easy to operate.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
