Abstract

An unmanned vehicle includes a body and a gimbal assembly arranged at the body. The body includes a bottom cover arranged at a bottom of the body. The gimbal assembly includes a shock-absorbing structure arranged inside the body and fixedly mounted at an inner bottom wall of the bottom cover, and a gimbal arranged outside the body and coupled to the shock-absorbing structure. The inner bottom wall is arranged inside the body and faces towards a top of the body.

First claim

What is claimed is:

1. An unmanned vehicle comprising:
a body including a receiving portion defined in the body; and
a gimbal assembly arranged at the body and including:
a gimbal arranged outside the body; and
a shock-absorbing structure arranged in the receiving portion of the body and including:
a shock-absorbing ball; and
a positioning structure including:
a fixing member connected to a first end of the shock-absorbing ball and an inner wall of the receiving portion; and
a moving member connected to a second end of the shock-absorbing ball and the gimbal, the second end of the shock-absorbing ball being farther away from the inner wall of the receiving portion than the first end of the shock-absorbing ball, and a part of the fixing member connected to the body being farther away from the inner wall of the receiving portion than a part of the moving member connected to the gimbal.

2. The unmanned vehicle of claim 1 , wherein the body further includes:
a main shell arranged above a bottom cover of the body, the bottom cover being detachably connected to the main shell.

3. The unmanned vehicle of claim 1 , wherein:
a peripheral portion of a bottom cover of the body extends toward a top of the body, forming a receiving space; and
the shock-absorbing structure is received in the receiving space.

4. 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.

5. 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.

6. 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.

7. 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.

8. 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.

9. 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.

10. 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.

11. 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.

12. 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.

13. 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.

14. The unmanned vehicle of claim 13 , wherein:
the connecting arm is a first connecting arm; and
the fixing member includes:
a positioning portion fixedly connected to the body;
a connecting portion extending from a side of the positioning portion;
a second connecting arm extending from an end of the connecting portion distal from the positioning portion, a distal end of the second connecting arm being connected to the shock-absorbing ball; and
a limiting portion fixedly connected to the positioning portion and approximately parallel to the positioning portion.

15. The unmanned vehicle of claim 14 , wherein:
the elastic sleeve is a first elastic sleeve;
the neck portion is a first neck portion; and
the shock-absorbing ball includes a second elastic sleeve configured to sleeve on a second neck portion provided at the distal end of the second connecting arm.

16. The unmanned vehicle of claim 15 , wherein:
the first elastic sleeve and the second elastic sleeve are arranged at opposite ends of the shock-absorbing ball.

17. The unmanned vehicle of claim 15 , wherein:
the first elastic sleeve includes a first sleeve through hole configured to sleeve on the first neck portion;
the second elastic sleeve includes a second sleeve through hole configured to sleeve on the second neck portion; and
a first sleeve direction of the first sleeve through hole is not parallel to a second sleeve direction of the second sleeve through hole.

18. The unmanned vehicle of claim 17 , wherein:
the first sleeve direction is perpendicular to the second sleeve direction.

19. The unmanned vehicle of claim 18 , wherein:
the shock-absorbing ball includes a first through hole and a second through hole;
a center of the second through hole coincides with a center of the shock-absorbing ball; and
an opening direction of the second through hole is perpendicular to an opening direction of the first through hole.

20. An unmanned vehicle comprising:
a body including a bottom cover arranged at a bottom of the body; and
a gimbal assembly arranged at the body and including:
a gimbal arranged outside the body; and
a shock-absorbing structure arranged inside the body and fixedly mounted at an inner bottom wall of the bottom cover, the inner bottom wall being arranged inside the body and facing towards a top of the body, and the shock-absorbing structure including:
a shock-absorbing ball; and
a positioning structure fixedly connecting the shock-absorbing ball to the body and including:
