and the shock-absorbing structure is received in the receiving space. ### Claim 4 (depends on 1) The unmanned vehicle of claim 1, wherein a mounting hole is provided at a bottom of a bottom cover of the body, the gimbal being fixedly connected to the shock-absorbing structure through the mounting hole. ### Claim 5 (depends on 4) The unmanned vehicle of claim 4, further comprising: a connecting structure arranged outside the body and connected between the shock-absorbing structure and the gimbal. ### Claim 6 (depends on 1) The unmanned vehicle of claim 1, wherein the fixing member includes: a positioning portion fixedly connected to the inner wall of the receiving portion, the positioning portion including: a plurality of positioning holes; and a plurality of fixing devices passing through the plurality of positioning holes and configured to lock the shock-absorbing structure on the inner wall of the receiving portion. ### Claim 7 (depends on 1) The unmanned vehicle of claim 1, wherein: the shock-absorbing ball is one of a plurality of shock-absorbing balls of the shock-absorbing structure; the fixing member is fixedly connected to an end of each of the plurality of shock-absorbing balls and the inner wall of the receiving portion; and the moving member is fixedly connected to another end of each of the plurality of shock-absorbing balls and the gimbal. ### Claim 8 (depends on 7) The unmanned vehicle of claim 7, wherein: the plurality of shock-absorbing balls are symmetrically arranged with respect to a center of the moving member or a center of the gimbal assembly; or the plurality of shock-absorbing balls are evenly distributed with respect to the center of the moving member or the center of the gimbal assembly. ### Claim 9 (depends on 7) The unmanned vehicle of claim 7, wherein: each of the plurality of shock-absorbing balls includes a through hole; and a center of the through hole coincides with a center of a corresponding one of the plurality of shock-absorbing balls. ### Claim 10 (depends on 9) The unmanned vehicle of claim 9, wherein: the plurality of shock-absorbing balls are arranged symmetrically with respect to a symmetry center; and a line connecting a center of the gimbal and the symmetry center is perpendicular to a centerline of an opening direction of the through hole of each of the plurality of shock-absorbing balls. ### Claim 11 (depends on 1) The unmanned vehicle of claim 1, wherein the moving member includes: a connecting plate fixedly connected to the gimbal; and a connecting arm extending from a side of the connecting plate, a distal portion of the connecting arm being connected to the shock-absorbing ball. ### Claim 12 (depends on 11) The unmanned vehicle according to claim 11, wherein the connecting plate is fixedly connected to the gimbal via a connecting structure, the connecting structure being arranged outside the body. ### Claim 13 (depends on 11) The unmanned vehicle of claim 11, wherein: the distal portion includes a neck portion; and the shock-absorbing ball includes an elastic sleeve configured to sleeve on the neck portion of the connecting arm. ### Claim 14 (depends on 13) The unmanned vehicle of claim 13, wherein: the connecting arm is a first connecting arm;
