Description
Technical field
This utility model is related to model plane field, more particularly to buffer unit field of rising and falling before model plane, specifically, is one
Plant the preposition undercarriage of fixed-wing model plane using double damping structure.
Background technology
Model plane constantly expand for modern society's application, be no longer only for entertainment with game product, just because
Thus, as modern model plane such as are applied to investigate, shoot, monitor, racing at the various fields.Existing model plane are roughly divided into fixation
Two kinds of the wing and rotor, and constantly from without engine driving to there is the conversion of engine-driven type.
In general, rotor model plane are usually based on single rotor or many rotor model plane, the characteristic flown due to which is as straight
Aircraft is risen, need not be slided in takeoff and landing substantially, so without the need for arranging the device similar to undercarriage, need to only set
Put cushioning and support device.And fixed-wing model plane, similar to Fixed Wing AirVehicle, either taking off or landing is required to
Sliding for certain length, varies in weight according to model plane, and required sliding speed and distance are otherwise varied.
Existing fixed-wing model plane, especially the fixed-wing model plane with fuel engines, as which has larger weight
And inertia, so the cushioning effect of its undercarriage is particularly important.Existing fixed-wing model plane undercarriage is generally using self-control
Or the model plane accessory of purchase specialty, homemade undercarriage stability is not ensured and buffering effect is poor, especially drops in model plane
When falling, as the elevation angle control of angle of landing is bad, cause undercarriage impact excessive, easily cause the damage of model plane wing and head
Wound even fractures；Carry out installing the high economy of its cost using the accessory of purchase specialty not strong, on the other hand, due to existing
The damping device of professional model plane undercarriage damping is carried out using telescopic spring cylinder, in the case of not high for ground flat degree, its
The effect of damping energy-absorbing is poor, and the shake to fuselage transmission is big, easily releases wing flap control system, causes unnecessary failure.
Utility model content
The purpose of this utility model is the preposition undercarriage of fixed-wing model plane for providing a kind of employing double damping structure, is used for
Solve the nose-gear of the existing fixed-wing model plane energy-absorbing when taking off bad, generation jolts big, be easily damaged airborne equipment and
Prolongation reaches the coasting distance of takeoff speed；Secondly, fixed-wing model plane are solved in landing, as nose-gear moment energy-absorbing is imitated
The really poor wing for causing, head contact to earth the unnecessary damage problem for causing.
This utility model is achieved through the following technical solutions：
A kind of fixed-wing model plane preposition undercarriage of employing double damping structure, it is including the installing plate being connected with model plane, described
Installing plate lower surface is connected with one end of the first force rod, and the other end of first force rod is hinged with the second force rod, institute
State and wheel is installed on the second force rod lower end, be provided with upper end the first spring for being connected with first force rod and
Second spring.
Installation of the present utility model and maintenance for convenience, it is preferable that the installing plate is rectangular to be arranged and near four
The position at angle is provided with installing hole；The installing plate lower surface center is welded with installation set, is provided with the installation set
Female thread.

Upper end is fixedly connected with the installation set by screw thread, and the first force rod lower end is fixedly connected with and second force rod
The hinge fork being hinged, is provided with two hooks for being respectively used to the first spring and second spring described in clamping in the middle part of the first force rod
Ring.
What deserves to be explained is:The selection of the amount of elasticity and length of first spring and second spring is entered according to following standard
OK：When this utility model is arranged on model plane, in model plane not by the case of external force, first spring and second spring it
Between angle be 40 ° -45 °, the acute angle between first force rod and the second force rod be 45 ° -50 °, when to model plane
When applying the weight with the model plane kerb weight G50%, distance of the model plane head lower surface apart from ground is compared and naturalness
The 80%-85% of former naturalness distance will be reduced into when lower.If in the case of above-mentioned pressure, model plane head lower surface distance ground
Value after the distance in face reduces is higher than 85%, and illustrate the first spring and second spring makes a concerted effort excessive relative to model plane deadweight, and which subtracts
Shake DeGrain, instantaneous energy-absorbing effect are poor；If value of the model plane head lower surface after the distance diminution on ground is less than 80%,
Illustrate the first spring and second spring make a concerted effort conduct oneself with dignity too small relative to model plane, substantially, instantaneous energy-absorbing effect is good for its damping effect,
But due to too soft, it is too low that elastically-deformable rated pressure value occurs, and easily causes head and surprisingly contacts to earth, rises before causing
The frame damping that falls is failed and causes the problem that model plane overturn.
Still more preferably, check washer is provided with the installation set, can make the first force rod with the installation set
Locking effect is played in firm connection, and its locking principle is：First force rod is connected with installation set by screw thread, when
When the termination of one force rod extend into installation set bottom and is resisted against on the check washer, locking pad described under pressure
Piece can prevent the first force rod relative to the loosening of the installation set.
