The present disclosure relates to a toy industry, and, more particularly, to a wall-climbing toy vehicle, and a bottom cover of such vehicle.
Wall-climbing toy vehicles are a new attraction among people, especially among children. Designing and manufacturing of the wall-climbing toy vehicles is a work of putting several scientific principles together. Designing and manufacturing a wall-climbing toy vehicle involves a lot of influence from science and that is why has been a field of constant innovation. More often than not, the user specially buys wall-climbing toy vehicle, which may exhibit characteristics like good withholding of car on wall, good maneuverability on the wall and so forth.
Whenever user chooses a wall-climbing toy vehicle, he/she is left over with lot of conventional wall-climbing toy vehicle in the market. Such conventional wall-climbing toy vehicles may be effective in meeting various requirements but may not be able to address some of the specific problems. For example, there may be the conventional wall-climbing toy vehicle which may climb on the wall but fall off the wall frequently due to less suction effect. Generally, such wall-climbing cars includes a bottom cover having a hole which enables air flow therefrom via a fan-motor assembly placed along the hole. Such hole may not be properly aligned or sized; or the fan-motor assembly may not be properly placed or aligned of along the hole. As a result, the conventional wall-climbing toy vehicle may not have sufficient air suction volume, thereby losing balance over the wall while climbing and may break upon repeated fall.
Further, there may be the conventional wall-climbing toy vehicle which may not be maneuvered on the curved section of the wall. For example, even if the convention wall-climbing vehicles may be designed to have greater suction volume, such wall-climbing vehicle with greater suction volume may not be able to have better maneuverability due to increased suction volume as bottom cover of such conventional wall-climbing toy vehicle may include plane and smooth surfaces.
Furthermore, there may be the conventional wall-climbing toy vehicle which may have less ground clearance with respect to the wall. As a result, the wall-climbing toy vehicle may not be able to climb the wall if any small obstacle comes in between.
Accordingly, there exists a need to overcome shortcomings of the existing wall-climbing toy vehicle. For example, there exists a need of a wall-climbing toy vehicle which may create substantial amount of suction effect to withhold the wall during climbing the wall. Further, there is need of such wall-climbing toy vehicle which may be able to balance with greater suction volume and be maneuverable on the curved section of the wall with ease. Further, there is need of such wall-climbing toy vehicle which may cross the obstacles coming between the wall and the wall-climbing toy vehicle, while climbing the wall. In this way, the user may get a wall-climbing toy vehicle which can climb the wall effectively without facing any hindrance.
In view of the foregoing disadvantages inherent in the prior art, the general purpose of the present disclosure is to provide a wall-climbing vehicle, and a bottom cover of such vehicle, to include all advantages of the prior art, and to overcome the drawbacks inherent in the prior art.
