Abstract
The utility model discloses a four-axis linkage for an engine compartment. The four-axis linkage comprises a front rocker, a rear rocker, and a servo motor. A rigid rod is fixed on each of the front rocker and the rear rocker. Power units are disposed at two ends of each rigid rod. The front rocker is connected with the servo motor through a pull rod. The front rocker and the rear rocker are connected together through a connecting rod. The four-axis linkage is good in synchronism, simple in structure and high in reliability; the front rocker and the rear rocker are connected through the connecting rod so as to allow four-axis linkage, power is increased, carrying capacity of an aircraft is increased, and power is stable, safe and reliable.
Description
Technical field
The utility model relates to model airplane field, especially relates to the four-axle linked mechanism of a kind of piggyback pod.
Background technology
Traditional aeromodelling airplane is generally divided into autogiro and fixed wing aircraft, autogiro flying speed is slow, and load carrying ability is low, and fixed wing aircraft take-off venue requires high, in the time taking photo by plane and investigate, because speed is inadequate, so manoevreability is poor, load carrying ability is low, so the detection equipment that aircraft can carry is limited, occasion limitation that can be applicable is larger, and the aircraft of fixed-wing can not be realized hovering, and autogiro speed is unhappy.
Utility model content
The utility model is for overcoming the above problems, provide a kind of piggyback pod four-axle linked mechanism for this reason, comprise front arm, rear arm and servomotor, on described front arm and rear arm, be fixedly installed stiff rod, the two ends of described stiff rod are provided with engine installation, described front arm and servomotor are coupled to each other by pull bar, and front arm and rear arm are coupled to each other by connecting rod.
As preferably, the bottom of described front arm is provided with engaging lug, and described engaging lug and pull bar are mutually permanently connected.
The beneficial effects of the utility model are: the utility model design is ingenious, and it is good to have synchronism, simple in structure, the advantage that reliability is high, and front and back are fixedly realized four-axle linked by connecting rod, improve power, increase planeload, and dynamical stability, safe and reliable.
Brief description of the drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is schematic side view of the present utility model;
Fig. 3 is the schematic perspective view of front swing arm;
In figure: 1, front arm; 2, rear arm; 3, stiff rod; 4, engine installation; 5, connecting rod; 6, servomotor; 7, pull bar.
Detailed description of the invention
Disclosed all features in this specification sheets, or step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary and accompanying drawing), unless narration especially all can be replaced by other equivalences or the alternative features with similar object.,, unless narration especially, each feature is an example in a series of equivalences or similar characteristics.
The four-axle linked mechanism of a kind of piggyback pod as depicted in figs. 1 and 2, comprise front arm 1, rear arm 2 and servomotor 6, on described front arm 1 and rear arm 2, be fixedly installed stiff rod 3, the two ends of described stiff rod 3 are provided with engine installation 4, described front arm 1 is coupled to each other by pull bar 7 with servomotor 6, and front arm 1 is coupled to each other by connecting rod 5 with rear arm 2.As shown in Figure 3, the bottom of described front arm 1 is provided with engaging lug 1.1, and described engaging lug 1.1 is mutually permanently connected with pull bar 7.Stiff rod 3 is fixedly installed on airframe, and described stiff rod 3 can rotate.
Pass through parallelogram lindage, pull front arm 1 with servomotor 6, and front arm 1 connects with the stiff rod 3 that connects left and right sides engine installation 4, thereby before realizing, piggyback pod rotates, and then power system adopts parallel four-bar linkage structure that rear arm 2 is connected with front arm 1, realize synchronous rotation, by controlling the amplitude of oscillation of servo, realize the change of engine installation 4 direction of pull, thereby realize the back and forth switching of aircraft between vertical hovering and level flight condition.The utility model design is ingenious, and it is good to have synchronism, simple in structure, the advantage that reliability is high, and front and back are fixedly realized four-axle linked by connecting rod, improve power, increase planeload, and dynamical stability, safe and reliable.
The utility model is not limited to aforesaid detailed description of the invention.The utility model expands to any new feature or any new combination disclosing in this manual, and the arbitrary new method disclosing or step or any new combination of process.
