Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a shock-absorbing support frame for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicle, abbreviated as UAV in English, is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device, or operated completely or intermittently autonomously by an on-board computer.

[0003] There is a bracket at the bottom of the drone, which is generally rigidly connected to the drone. The rigid connection causes the vibration force of the bracket landing on the ground to be transmitted to the drone body, affecting the service life of the drone. As the usage time increases, the connection between the bracket and the drone may also become loose.

[0004] Therefore, in order to solve the above problems, the utility model proposes a shock-absorbing support frame for a drone. Utility Model Content

[0005] The purpose of the utility model is to provide a shock-absorbing support frame for a drone to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a shock-absorbing support frame for an unmanned aerial vehicle, comprising a body, a plurality of symmetrically arranged upright blocks are fixedly connected to the bottom end of the body, a plurality of upright blocks are rotatably connected to a rotating rod, two outer walls of the rotating rods are fixedly connected to a bracket, the mutually distant surfaces of the plurality of upright blocks are fixedly connected to a blocking block, two square blocks are fixedly connected at the positions of the two rotating rods corresponding to the blocking blocks, two outer walls of the rotating rods are fixedly connected to a transmission gear, two side walls of the body are fixedly connected to a support plate, the two support plates are rotatably connected to an adjusting screw rod, the two support plates are slidably connected to a symmetrically arranged limit rod, the bottom ends of the limit rods are jointly fixedly connected to an adjusting plate, the two adjusting plates are slidably connected to a symmetrically arranged connecting rod, the bottom ends of the connecting rods are jointly fixedly connected to a lifting plate, the top of the lifting plate is fixedly connected to a spring at the position corresponding to the connecting rod, and the bottom ends of the lifting plates are fixedly connected to a symmetrically arranged transmission rack.

[0007] Preferably, the adjusting screw is located in the middle of the adjusting plate, and the adjusting screw is threadedly connected to the adjusting plate.

[0008] Preferably, the two connecting rods are both located at the hollow position of the spring, and the top end of the spring is fixedly connected to the bottom end of the adjustment plate.

[0009] Preferably, the transmission racks are all meshingly connected with the transmission gears.

[0010] Preferably, the top end of the adjusting screw rod is fixedly connected with a handle, and the handle is circular in shape.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: a transmission gear, a transmission rack, an adjusting bolt and a spring, etc. are provided. When the bracket at the bottom end of the drone body falls to the ground, the vibration force of the landing will cause the transmission gear to rotate, and the rotation of the transmission gear will cause the various mechanisms to be linked, so that the lifting plate squeezes the spring. The process of the spring contraction and popping out can convert the force of the bracket falling to the ground from rigidity to flexibility, preventing the rigid vibration force from being completely transferred to the drone body, which can stably improve the service life of the drone body, and can also prevent the loosening of the connection between the bracket and the drone body, and the position of the adjusting plate and the spring can be adjusted by adjusting the bolt, so as to achieve the purpose of adjusting the shock absorption force.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3The utility model provides a technical solution: a shock-absorbing support frame for an unmanned aerial vehicle, comprising a body 1, a plurality of symmetrically arranged upright blocks 2 are fixedly connected to the bottom end of the body 1, a rotating rod 3 is rotatably connected between the plurality of upright blocks 2, a bracket 4 is fixedly connected to the outer walls of the two rotating rods 3, and the mutually distant surfaces of the plurality of upright blocks 2 are fixedly connected to blocking blocks 5, and the two rotating rods 3 are fixedly connected to square blocks 6 at the positions corresponding to the blocking blocks 5, and the outer walls of the two rotating rods 3 are fixedly connected to transmission gears 7, and the two side walls of the body 1 are fixedly connected to support plates 8, and the two support plates 8 are rotatably connected to adjusting screw rods 9, and the two support plates 8 are slidably connected to symmetrically arranged limit rods 10, and the bottom ends of the limit rods 10 are commonly fixedly connected to an adjusting plate 11, and the two adjusting plates 11 are slidably connected to symmetrically arranged connecting rods 12, and the bottom ends of the connecting rods 12 are commonly fixedly connected to a lifting plate 13, and the top of the lifting plate 13 is fixedly connected to a spring 14 at the position corresponding to the connecting rod 12, and the bottom ends of the lifting plates 13 are fixedly connected to symmetrically arranged transmission racks 15.

[0018] Furthermore, the adjusting screw rod 9 is located at the middle position of the adjusting plate 11 , and the adjusting screw rod 9 is threadedly connected to the adjusting plate 11 , so that the adjusting screw rod 9 can easily drive the adjusting plate 11 to move.

[0019] Furthermore, the two connecting rods 12 are both located at the hollow position of the spring 14 , and the top end of the spring 14 is fixedly connected to the bottom end of the adjustment plate 11 .

[0020] Furthermore, the transmission racks 15 are meshed and connected with the transmission gears 7 so as to drive the transmission racks 15 to move.

[0021] Furthermore, a handle 16 is fixedly connected to the top of the adjusting screw rod 9 . The handle 16 is circular in shape, and the handle 16 facilitates the rotation of the adjusting screw rod 9 .

[0022] Specifically, when the utility model is used, when the machine body 1 lands with the bracket 4, the impact force of the landing will act on the bracket 4, and the bracket 4 cannot rotate downward at this time because the square block 6 on the rotating rod 3 is in contact with the blocking block 5. When the bracket 4 is impacted and rotates upward, the rotating rod 3 and the transmission gear 7 will be driven to rotate, and the transmission gear 7 will drive the transmission rack 15 to move upward. The upward movement of the transmission rack 15 will drive the lifting plate 13 and the connecting rod 12 to move upward. The upward movement of the lifting plate 13 will squeeze and contract the spring 14. The contraction process of the spring 14 will convert the impact force from rigidity to flexibility, and at the same time, the spring 14 will When the spring 14 has absorbed the impact, it will also rebound and return. The contraction and return rebound of the spring 14 can convert the maximum absorption of the impact force, thereby achieving the purpose of shock absorption for the body 1. When the rebound amplitude of the spring 14 needs to be adjusted, the adjusting screw 9 can be rotated through the handle 16. The adjusting screw 9 will drive the adjusting plate 11 to move downward. When the adjusting plate 11 moves downward, the spring 14 will be squeezed and contracted, and the position of the lifting plate 13 remains unchanged, because at this time the transmission gear 7 and the transmission rack 15 are in a connected state, and the rotating rod 3 cannot be rotated downward, and then the adjusting plate 11 squeezes the spring 14 to a suitable state to complete the adjustment.
