Abstract

The utility model provides a strong-balance toy vehicle, which comprises a vehicle casing, a chassis and a rear axle assembly. An integrally connected anti-vibration device is arranged between the rear axle assembly and the chassis. The strong-balance toy vehicle is characterized in that the anti-vibration device includes a connecting shaft and an anti-vibration spring, wherein the connecting shaft is installed at the middle position at the rear lower end of the rear axle assembly capable of swinging around the connecting shaft, and the anti-vibration spring is mounted above the connecting shaft. As a baffle plate capable of tightly compressing the anti-vibration spring is arranged on the chassis, the rear axle assembly can rotate by adopting the connecting shaft as a shaft core according to the conditions of the height of a road surface when the toy vehicle runs on an uneven road surface in running process, thereby enabling rear wheels of the toy vehicle to relatively swinging and accordingly ensuring stable running of the toy vehicle. Moreover, as the anti-vibration spring is arranged at the middle position, buffering and returning functions of the anti-vibration spring can be improved when the rear axle assembly swings, sensitivity of the toy vehicle is strengthened, and the toy vehicle suitable for running on various uneven road surfaces can be widely applied to toy industry.

Description

The toy car that balance is strong

Technical field

The utility model relates to a kind of toy car, specifically is the strong toy car of a kind of balance.

Background technology

Along with the extensive use of electronic technology in the toy car industry, remote-controlled electric toy car miscellaneous also enters the entertainment for children field thereupon, yet the trailing wheel and the drive unit thereof of the most of cars of existing remote-controlled electric toy car all are arranged on the car body, like this when the car instability of travelling, overturn easily.In order to address the above problem, someone adopts at the trailing wheel of car body and drive unit thereof and is installed on another rear axle assy that is independent of car body, and between car body and rear axle assy, be provided with and include shock-proof spring, the shock absorbing apparatus of connecting axle and fixture block and draw-in groove, wherein shock-proof spring is for vertically being provided with and being positioned at the rear axle assy both sides, when motion is shaken on car travels road surface in injustice like this, rear axle assy can be with respect to the car body swing, compress shock-proof spring simultaneously, whole vibrations are cushioned to some extent, thereby improved the moving equilibrium of toy car effectively, but the structure of this shock absorbing apparatus is too complicated, not only make the overall weight of toy car increase, manufacturing cost improves, and cause it to connect also more complicated, and inconvenient disassembling, assembling and replacing, and shock-proof spring vertically is provided with the shortage sensitivity, the rotation amplitude of whole rear axle assy is little, can better not bring into play the balance quality of toy car.

Summary of the invention

At above-mentioned existing in prior technology problem, it is ingenious, simple in structure that the purpose of this utility model provides a kind of design, fundamentally solve the toy car problem that the four-wheel equilibrium lands when various road traveling, can satisfy the strong toy car of balance of child's the enjoyment of playing, the strong toy car of balance of conveniently replaced rear axle assy further is provided on this basis.

For achieving the above object, the technical scheme that the utility model adopted is: the toy car that a kind of balance is strong, comprise car shell, chassis and include rear wheel and the rear axle assy of drive unit, be provided with shock absorbing apparatus between described rear axle assy and the chassis, the latter half of cavity that is provided with that it is characterized in that described chassis, described rear axle assy is arranged in the cavity of chassis, and described shock absorbing apparatus comprises that the connecting axle, the device that are connected with the cavity of rear axle assy and chassis bump the shock-proof spring that connects on rear axle assy and with the cavity rear portion of chassis.

Wherein, above-mentioned connecting axle is installed on above-mentioned rear axle assy posterior end position intermediate, and above-mentioned shock-proof spring is installed on the top of described connecting axle.

In order to guarantee this toy car easy accessibility, can change rear axle assy as required, above-mentioned chassis is formed by connecting by preceding chassis and back chassis, above-mentioned rear axle assy is installed on the chassis of described back by above-mentioned shock absorbing apparatus, so when changing rear axle assy, only need the back chassis is removed, the back chassis of changing other rear axle assy places gets final product.

The utility model is because employing is provided with the cavity of placing for rear axle assy at chassis, and the structure that chassis and rear axle assy is linked into an integrated entity by the shock absorbing apparatus formed by connecting axle and shock-proof spring, so when toy car runs into uneven road surface in the process of moving, particularly rear wheel runs into when being uneven, rear axle assy can be that a core rotates with connecting axle according to the situation of road surface height, make that the rear wheel of toy car is relative or high or low about front vehicle wheel or high or low or rear wheel relatively, thereby make toy car remain balance, guarantee the toy car smooth-ride, and shock-proof spring is arranged on the centre position, effect during shock-proof spring cushions and returns when having improved the rear axle assy swing effectively, make its sensitivity stronger, further make toy car be adapted to travel on the various uneven road surfaces; Again owing to preceding chassis is connected with circular hole by cylinder with the back chassis, and rear axle assy is installed on the chassis of described back by above-mentioned shock absorbing apparatus, therefore can be on each back chassis with different shock absorbing apparatus and rear axle assy device, child can change the back chassis as required when being at play, thereby reach the effect of changing shock absorbing apparatus and rear axle assy, but also can improve child's manipulative ability, improve child's critical thinking, the selection of simultaneously multiple back chassis can be satisfied child's the enjoyment of playing, and can obtain more children's favor.In sum, the toy car that balance described in the utility model is strong, its design is ingenious, simple in structure, balance quality is strong, adapt to various uneven road surfaces and travel, and disassembling, assembling and replacing is convenient and swift, child's the enjoyment of playing can be satisfied, toy industry can be widely used in.

The utility model is described in further detail below in conjunction with drawings and Examples.
