Specific embodiment
To make the objectives, technical solutions and advantages of the present invention clearer, below by shown in the accompanying drawings
Specific embodiment describes the utility model.However, it should be understood that these descriptions are merely illustrative, and it is not intended to limit this reality
With novel range.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid unnecessarily mixing
Confuse the concept of the utility model.
Here, it should also be noted that, in order to avoid having obscured the utility model because of unnecessary details, in the accompanying drawings
It illustrate only the structure and/or processing step closely related with scheme according to the present utility model, and be omitted practical with this
The little other details of new relationship.
As shown in Figure 1, Figure 2, Figure 3 shows, present embodiment uses following technical scheme: it includes body 1, quadrotor bar
Body 2, landing cushioning and supporting device；The quadrotor body of rod 2 is fixedly installed on the lateral wall of body 1, the bottom of the quadrotor body of rod 2 is solid
Equipped with landing cushioning and supporting device, the landing cushioning and supporting device includes shell 3, piston 4, reset spring 5, piston rod for Dingan County
6, rubber block 7, capping 8；The inside of shell 3 offers loose slot, and loose slot can be realized the activity of piston, and piston lateral wall
Sealing ring can be tightly connected with loose slot, piston 4 and loose slot are sealed and are flexibly connected, the bottom fixed installation of piston 4
There is piston rod 6, piston rod is used as support rod, can be realized stable support, and the bottom of piston rod 6 is fixedly installed with rubber
Block 7, rubber block 7 can support on the ground, and rubber block itself has the efficiency of buffer strength, further to improve buffering effect
The upper end of rate, piston rod 6 is fixedly connected by reset spring 5 with the bottom of loose slot, and the front end of shell 3 is fixedly installed with capping
8, housing seal is an entirety by capping 8, so that the silicone oil of enclosure interior is not easy to flow out, and is covered 8 and is connected with the sealing of shell 3
It connects, the middle part for covering 8 offers circular hole groove body, and circular hole groove body is sealed and is flexibly connected with piston rod 6, opens up on the piston 4
There are two symmetrical hole slot 4-1, silicone oil is marked in shell 3.
Further, the rubber block 7 is hollow type rubber block.
Further, the outside of the shell 3 is socketed with rubber sleeve.
The working principle of the present embodiment is as follows: landing cushioning and supporting device is mounted on the quadrotor body of rod on body 1
The support and buffer strength when landing are realized by landing cushioning and supporting device in lower end, while when in use, piston 4 is in shell
Carry out activity in body 3, and the reset spring 5 on piston 4 can be realized the buffering of dynamics, and can be realized work when dynamics disappears
The reset of plug is realized by rubber block 7 and is supported in support, and rubber block 7 can be realized buffer-type support, can be improved steady
Qualitative, shell 38 can be sealed into an entirety by capping, and the intracorporal silicone oil of shell can be realized pressure balance, when needing pressure
When, when piston moves up, the downside that the oil of piston on the side has hole slot to enter piston can reduce shaking dynamics, be effectively protected
Fuselage.
