Description
Technical field
This utility model is specifically related to a kind of undercarriage cushioning device.
Background technology
Unmanned plane undercarriage does not has damping device, only minority to use prestressing force mode damping mostly.The most not only land
Time can to part strength member produce impact, and just in case unmanned plane land the fastest or out of control falling be easy to break undercarriage very
To body.
Utility model content
For existing issue, the utility model discloses a kind of undercarriage cushioning device, it can effectively reduce unmanned plane
Impact during landing, it is ensured that unmanned plane body is injury-free.
The technical solution of the utility model is as follows:
A kind of undercarriage cushioning device, connects the carbon fiber pipe of undercarriage, sets below described carbon fiber pipe including a upper end
There is a connection piece, below described connector, be provided with a damping oil cylinder；The lower end of described damping oil cylinder connects one end of a connecting rod one,
The other end of described connecting rod one connects connecting rod two one end, and the other end of described connecting rod two connects described connector；Described damping
Oil cylinder is arranged with a spring；The adjustable pipe that damping oil cylinder can be slided by a cylinder body and the top of lower section in cylinder body forms.
The utility model proposes a kind of undercarriage cushioning device, it is possible to effectively reduce the unmanned plane impulse force when landing,
Ensure that unmanned plane body is injury-free.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, required in embodiment being described below
Accompanying drawing to be used is briefly described.
Fig. 1 is the structure chart of the undercarriage cushioning device that the utility model proposes.
In figure, numeral represents:
1, carbon fiber pipe 2, connector 3, damping oil cylinder 4, connecting rod 1, connecting rod two
6, spring.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe.
Shown in Fig. 1, a kind of undercarriage cushioning device, the carbon fiber pipe 1 of undercarriage, carbon fiber pipe 1 is connected including a upper end
Lighter in weight, has the advantage reducing unmanned plane deadweight；A connection piece 2, described connector 2 it is provided with below described carbon fiber pipe 1
Lower section is provided with a damping oil cylinder 3；The adjustable pipe group that damping oil cylinder 3 can be slided by a cylinder body and the top of lower section in cylinder body
Become, place hydraulic oil in cylinder body, by the kinetic energy above the resistance of hydraulic oil and then buffering when adjustable pipe is moved down by compression；Described
The lower end of damping oil cylinder 3 connects one end of a connecting rod 1, and the other end of described connecting rod 1 connects connecting rod 25 one end, described
The other end of connecting rod 25 connects described connector 2；Connecting rod 1 and connecting rod 25 form push and pull system, push and pull system and connector 2
Form a transformable triangular support system, it is possible to well ensure stability during unmanned plane landing；Described damping oil
Cylinder 3 is arranged with a spring 6, and spring 6 is to buffer kinetic energy during unmanned plane landing further.
The utility model proposes a kind of undercarriage cushioning device, it is possible to effectively reduce the unmanned plane impulse force when landing,
Ensure that unmanned plane body is injury-free.
Multiple amendment to these embodiments will be apparent from, herein for those skilled in the art
Defined General Principle can be real in other embodiments in the case of without departing from spirit or scope of the present utility model
Existing.
