Description

The land sailing toy vehicle

Technical field:

The present invention relates to toy vehicle, especially relate to and adopt that the controlled in wireless mode is controlled, as to be with sail and wheel land toy vehicle by the wind-force promotion.

Background technology:

Can see the multiple toy vehicle of being used by toy and a large amount of amusement of wind-force promotion on the market, these all can be referred to as the land toy vehicle.These land toy vehicles have a sail that is used to catch wind-force, and the main body that sail is installed, and in addition, it also includes the wheel that is used for supportive body.In general, these toy vehicles are controlled by wireless signal, and it totally is the triangular shape structure, and it has a pair of trailing wheel and front-wheel that is used to turn to that is positioned at the rear axle two ends.Servo motor/receiver is installed to receive the wireless remote control signal that controller sends on these toy vehicles.Under the control of wireless signal, receiver and servo motor can alternately be controlled the front-wheel and the sail drive unit of the front wheel guide device on the main body.

There is a problem in such toy vehicle, promptly occurs the uncontrollable trend of toppling under the effect of high wind easily.In order to address this problem, the designer has done multiple effort, such as using flexible outer assembly wheel, special distribution of weight and regulating position of centre of gravity of vehicle and two wheels or the like.But these want that the effort that makes vehicle keep stable is not very successful when high-speed row.In addition, the Mast Controller that draws with line makes vehicle have the such mobility of sailing boat and also exists problem, its reason is: when mast rocks, the backguy meeting fluffs, and the device (using spool or capstan usually) of control backguy length tangles the threads easily, thereby disturbs the work of mast control system.

For this type toy vehicle that runs up, mast control and direction control are key points.This point is from preceding laid-open U.S. Patents application such as US 4,886,478 and 6,576, and 146 as can be seen.In U.S. Pat 4,886, the toy vehicle of describing in 478, the motion of its mast is limit by the backguy of a pine, and its front-wheel direction-control apparatus then comprises a pair of hawser that extends to front-wheel from the servo motor that is installed on the toy car rear end.And 6,576,146 toy vehicles that disclose another kind of form of United States Patent (USP), the backguy of its Mast Controller does not have guide frame, and extends a backguy of linking the control arm on the front-wheel from the servo motor of its control front-wheel.Toy vehicle during above-mentioned two kinds of directions and mast control system all can't make and be run up by being in of wind drive keeps stable state really.And above-mentioned two kinds of associated documents all do not provide any method that prevents that vehicle from toppling over.

The inventor wants to propose a kind of controllable and unlikely toy vehicle by wind drive of toppling over when running up now.The cost of this toy vehicle is cheap relatively, and the degree of reliability in when running is very high.

Summary of the invention:

The purpose of this utility model is exactly in order to overcome in the prior art by the existing unstability of the land toy vehicle of wind drive and easy pourability problem.For achieving the above object, the utility model comprises the parts of a plurality of novelties, as driving the worm gear arrangement of front-wheel; The mast control device of several uniquenesses, and round front-wheel steer assembly brake disc all around.

Desirable mast control device should allow mast can locate fast and stably so that prominent next external force is unlikely to focus on the vehicle.Adopting backguy to control mast is preferable mode, but because mast can freely swing, it may produce unnecessary pulling force and easy mat to vehicle, thereby influences the stability that vehicle is advanced as described above.In order to improve the mast control effect of sail, the inventor provides the technical scheme of three kinds of novelties, the backguy of these three kinds of modes or use tape guide structure or drive mechanism and pinion or the elastic band device of sliding, and the back will be described in detail.
