The invention discloses an unmanned aerial vehicle undercarriage, and belongs to the field of undercarriages, the unmanned aerial vehicle undercarriage comprises an unmanned aerial vehicle body and an undercarriage body, through arrangement of second buffer mechanisms, when the unmanned aerial vehicle body lands and the undercarriage body is subjected to impact force, the degree of an included angle formed between symmetrical second buffer rods is gradually reduced; in the changing process, connecting blocks are pushed towards the inner side direction through upper concave blocks, so that the symmetrical connecting blocks do relative movement operation along the fixing rods through connecting holes, and second buffer springs are forced to do retraction operation; the impact force brought by the undercarriage body is further absorbed and counteracted through the elastic deformation of the second buffer springs, and the undercarriage body can have a dual-buffer effect through the cooperative use of the first buffer mechanism, so that the impact resistance, the stability and the buffer effect of the undercarriage body and the unmanned aerial vehicle body are improved; and unnecessary damage to the unmanned aerial vehicle body is prevented.

    本发明公开了一种无人机起落架,属于起落架领域,包括无人机本体和起落架本体,通过设置的第二缓冲机构,当无人机本体降落且起落架本体受到冲击力时,对称的第二缓冲杆之间所形成的夹角度数将逐渐变小,并在发生变化的过程中通过上方的凹型块向内侧方向推动连接块,使对称的连接块通过连接孔顺着固定杆做出相对移动操作,并迫使第二缓冲弹簧做出缩进操作,以通过第二缓冲弹簧的弹性形变来进一步地吸收并抵消起落架本体带来的冲击力,并通过第一缓冲机构的配合使用可使起落架本体具有双重缓冲的作用,从而提高起落架本体和对无人机本体的抗冲击和稳定性能以及缓冲效果,防止无人机本体出现不必要的损坏。
