Description

A kind of remote-controlled toy vehicle

Technical field

The utility model relates to the toy technique field, particularly relates to a kind of remote-controlled toy vehicle.

Background technology

In the existing remote-controlled toy vehicle, generally have only comparatively simply and advance, retreat, about turn to, stop to wait action, seldom there is the single-wheel that can simulate true car to raise unsettled and forms the nose walking, cause its action single, lack interest and new meaning, reduced user's interest, at this situation, have on the market now some remote-controlled toy vehicles be provided with can nose action, but its effect is undesirable, generally have only unidirectional nose action, particularly its nose walking is very unreliable, and stability and persistence are poor, influence it and manipulate, reduced the interest of toy car.

Summary of the invention

The purpose of this utility model is the problem at above-mentioned existence, provides a kind of and has two-way nose walking function, and remote-controlled toy vehicle simple in structure, that action is reliable and stable, easy and simple to handle.On this basis, further purpose of the present utility model provides a kind of remote-controlled toy vehicle flexible, simple in structure, reliable in action that turns to.

The technical solution of the utility model is achieved in that

A kind of remote-controlled toy vehicle, comprise chassis and the car face-piece assembly of device on chassis, be characterized in that chassis comprises chassis, drive unit, left and right wheel, disk cover assembly, wherein the drive unit device is in the chassis, left and right wheel assembly is connected in the both sides, chassis and with drive unit, but the disk cover assembly comprises disk cover, installs the battery case at the two trundle device batteries at disk cover two ends, wherein the disk cover lid is put on the chassis and with the chassis and is connected as one removably, and battery pack device is at the medium position of disk cover.

Two-way nose walking of the present utility model is easier, action is more stable in order further to make, reliable and lasting, the utility model also includes the counter weight device that can regulate the vehicle's center of gravity position, this counter weight device comprises casing, balancing weight, wherein box body device is in car face-piece assembly or chassis, and balancing weight can forward and backwardly rollably be arranged in the casing.

For realizing further purpose of the present utility model, above-mentioned drive unit comprises two motors, two groups of driving gear set, wherein two motors install symmetrically at the forward and backward two ends of chassis cavity, two groups of driving gear set are installed respectively at the chassis cavity both ends, and the input of two groups of driving gear set is connected with the output shaft of two motors respectively, and its output is connected with left and right wheel respectively and the transmission left and right wheels.

The utility model is owing to adopt to improve the rigging position of battery dexterously and each position component structure that distributes symmetrically, the center of gravity of whole vehicle brought up to suitable height and it is adjusted on the symmetrical plane of front and back wheel.Like this, when vehicle in craspedodrome and suddenly under the situation of urgent reverse driving, the liftoff perk of vehicle one end under action of inertia and have only the walking that lands of other end wheel realizes the two-way nose walking function of vehicle reliably.Simultaneously by ballast box is set in car body and in ballast box the device balancing weight structure, because being provided with suitable cavity, ballast box can allow the balancing weight segment distance that rolls neatly before and after within it, strengthened action of inertia, made vehicle one end perk and have only the walking that lands of other end wheel easilier.Simultaneously owing to adopt the mode of four-wheel drive, use two motors respectively to drive one group of driving gear set and drive two left side wheel or two right side wheels separately, and form the different rotation directions combination of both sides wheel by the direction of rotation that changes two motors, thereby realize reliably advancing, retreat, about the function that turns to.The utility model increases the balancing weight of a roller in particular, the cost increase seldom, but performance improved greatly, improved the reliability and the persistence of two-way nose walking function widely, it is more free and relaxed that toy car is operated.
