Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is control principle drawing of the present utility model.
In figure, 1. support frame, 11. drag reduction perforation, supporting leg on 21., 22. lower support leg, 3. horizon sensors, 4. the first rotating mechanism, 5. the second rotating mechanism, 6. telescoping mechanism, 7. pressure sensor.
Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of full landform helicopter landing gear, comprise controller, support frame 1 and four supporting legs, the top of described supporting leg is connected on described support frame 1, described support frame 1 is provided with horizon sensor 3, to measure described support frame 1 whether level.The number of described supporting leg also can be set according to the weight of the support strength of described supporting leg and helicopter in other embodiments.
Described supporting leg comprises supporting leg 21 and lower support leg 22, described upper supporting leg 21 is connected by the first rotating mechanism 4 with described lower support leg 22, described upper supporting leg 21 is connected by the second rotating mechanism 5 with described support frame 1, the S. A. of described first rotating mechanism 4 and the S. A. of described second rotating mechanism 5 are parallel to described support frame 1 respectively, described lower support leg 22 includes telescoping mechanism 6, described telescoping mechanism 6 is arranged on described lower support midleg, the expansion link of described telescoping mechanism 6 is arranged so that described lower support leg 22 is along its axial stretching along the axis along described lower support leg 22, described in concrete enforcement, telescoping mechanism can be arranged on the middle part of described lower support leg 22, the expansion link of described telescoping mechanism and described lower support leg 22 coaxial line, also described telescoping mechanism can be arranged on the part of one end as described lower support leg 22 for described lower support leg 22, described lower support leg 22 also can be made along the object of its axial stretching.
The bottom of described lower support leg 22 is provided with the pressure sensor 7 that connects described controller for the contact of lower support leg described in perception 22 with ground.
Described controller connects described first rotating mechanism 4, described second rotating mechanism 5, described telescoping mechanism 6, described horizon sensor 3 and described pressure sensor 7 respectively, when described horizon sensor 3 senses horizontal signal, described sensor also adjusts described first rotating mechanism 4, the described anglec of rotation of the second rotating mechanism 5 and the collapsing length of described telescoping mechanism 6 according to the horizontal signal of described horizon sensor 3, makes described support frame 1 maintain horizontality.When described pressure sensor 7 senses that contact does not reach preset pressure, even if when described support frame 1 is level, described first rotating mechanism 4 of described controller adjustment respective support leg, described second rotating mechanism 5 and described telescoping mechanism 6, when contact reaches preset value, respective support leg is fixed.This set can prevent described support frame 1 level and the unsettled situation of one or more supporting leg, keeps the level of described support frame 1 and stable, thus realizes the level of helicopter and stable, is adapted to full landform landing.
Described supporting leg is symmetrical arranged along the left and right sides of described support frame 1, agrees with the constructional feature of helicopter, enhances steadiness of the present utility model.
Described in concrete enforcement, telescoping mechanism 6 is set to hydraulic telescopic machanism, also can be arranged to the telescoping mechanisms such as electric expansion bar, cylinder to reach the object that can stretch.
