Description

Transmission mechanism of airplane toys

The utility model relates to an innovative design of an airplane toy, especially refers to an airplane toy that, after being started, will produce movements of rising, rotating, and falling of the body, and a small ornamental model is pre-buried in the top of the body, and can also be used by the inside The action of the transmission mechanism produces a transmission mechanism for special actions such as rising and protruding out of the outer top of the fuselage.

Generally, the design of common aircraft toys tends to be polarized. One is to win by the appearance, and supplemented by relatively simple actions (such as: body movement, etc.) to increase its variability. The kung fu is too old to be new, and it cannot produce wonderful and diverse movements, nor can it meet the high requirements of today's children for innovation and change. For this reason, the producer develops the transmission structure of the airplane toy towards another characteristic of a single airplane toy with multi-directional special actions. It becomes extremely complicated, not only the cost is higher, but also the failure rate of the toy increases accordingly. Therefore, how to make a balance between cost pressure, durability and exciting and diverse actions is an important issue for ordinary manufacturers.

The purpose of the utility model is to provide a transmission mechanism of an airplane toy with diversified actions, relatively simple structure and low cost.

The purpose of this utility model is achieved in that the utility model is mainly made up of parts such as cabinet, rotary power wheel group and lifting support.

As for the detailed structure, application principle, function and effect of the present utility model, then can obtain complete understanding with reference to the explanation that following accompanying drawing is done:

Fig. 1 is a schematic diagram of the overall combination of the utility model.

Fig. 2 is an overall exploded view of the utility model.

Fig. 3 is a schematic diagram of the operation of the internal components of the chassis of the utility model.

Fig. 4 is a schematic diagram of the action between the small aircraft model of the present invention and the body cover door.

Fig. 5 is a diagram of a preferred embodiment of the utility model.

Please refer to the drawings, it can be seen from the drawings that the utility model is mainly provided with a prime mover 11 such as a motor at one end of the cabinet 1, and the prime mover 11 is respectively connected with a gear set 12 with a joint in the up and down direction. Rotating shaft 21 and a driving shaft 13 arranged front and back, the bottom end of the connecting rotating shaft 21 stretches out of the cabinet 1 and the body 9, and a rotating power wheel set 2 is provided, and the transmission gear 22 meshing with the appropriate position on the connecting rotating shaft 21 A connecting gear set 121 is connected; a driven gear 131 is provided at the front end of the above-mentioned drive shaft 13, and two cams 132 and 133 with inconsistent convex directions are respectively provided at two appropriate positions toward the tail end, and one of the cams 132 is correspondingly arranged on a On the top of the lifting support 3, when the cam 132 rotates downward, the pressing lifting support 3 can be moved downward relatively, and the other cam 133 is relatively arranged below the decorative body support piece 5, and can be transferred on the cam 33. When it is in the upper position, move the decoration support piece 5 upwards; moreover, the two sides of the cabinet 1 are provided with a slot 14 facing up and down, and the slot 14 is for a moving rod 32 to pass through, and the moving rod 32 is inside the cabinet 1 Knot the lifting support shaft 3, and display the two ends of the moving rod 32 respectively outside the slot 14, and be elastically supported by an elastic element 4 from bottom to top, and the top of the lifting support shaft 31 is provided with a rotating gear 7, The lifting support 3 is pivotally connected with a lifting support shaft 31 downwards, and a base is provided at the bottom of the lifting support shaft 31. Therefore, when the cam 132 corresponding to the lifting support 3 rotates downward, it can just press the lifting support. The seat 3 descends, and when it reaches the bottom dead point, the rotating gear 7 on it is correspondingly meshed with the connecting gear set 121; the above-mentioned decorative body brace 5 has a pivot end 51 for pivoting on the chassis 1, and its other The free end is then provided with a decorative body 52 (which can be a small aircraft), and is hooked between the decorative body strut 5 and the chassis 1 by an elastic element 6, so that the normal pulling decorative body strut 5 has a downward tendency .

According to the above-mentioned structural combination, the overall action of the utility model is: when the prime mover 11 is energized, the gear set 12 is driven to continuously drive the connecting shaft 21, so as to drive the connecting gear set 121 and a rotating power wheel set 2 to rotate, so that the airplane toy Walking around, at this time, the connecting gear set 121 also drives the driven gear 131 of the driving shaft 13 to rotate, so that the two cams 132, 133 on the shaft body rotate synchronously, and when the cam 132 corresponding to the lifting support 3 is pressed downward, the Make the lifting support 3 move downwards, the moving rod 32 also moves down synchronously along the guiding direction of the slot 14, and the elastic element 4 outside the cabinet 1 is also pressed down by the moving rod 32 to the bottom dead point of the slot 14 , at this stage, the aircraft body 9 is supported by the lifting support 3 and presents an upward movement, the rotating power wheel set 2 has no effect because it is off the ground, and the rotating gear 7 at the top of the lifting support 3 is descending and connecting with the gear set 121 engages and rotates, so that the lifting support 3 and the lifting support shaft 31 can rotate, and then the aircraft body 9 can also rotate in situ. Pushing the decorative body support piece 5 makes it take the pivot joint end 51 as the fulcrum to generate an upward tilting action, so that the decorative body 52 at the front end of the decorative body support piece 5 can rise and push the top to open the preset cover door on the top of the body 9 8. Present the ornamental body 52 on the outer top of the body 9, and when the two cams 132, 133 are transferred to the opposite positions respectively, the body 9 and the ornamental body 52 will be lowered back to their original positions respectively, and the original action will be restored.

From the above, it can be seen that the transmission structure of the airplane toy of the present invention does have a variety of wonderful changing actions, and the structure is relatively simple, the cost is low, and the advantages of increasing interest and attractiveness can improve common airplane toys and diversify actions. Relatively simple, complicated structure, the shortcoming of higher cost.
