Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A wheel carrier 100 for mounting on a toy vehicle according to an embodiment of the present invention will now be described with reference to fig. 1-9.
According to the wheel frame 100 for mounting on the toy vehicle of the embodiment of the invention, the wheels 1 are arranged on the wheel frame 100, the movable brake assembly 5 is also arranged on the wheel frame 100, and when the side part of the wheel frame 100 collides with an obstacle, the brake assembly 5 can move towards the obstacle and contact with the obstacle, so as to reduce the running speed of the toy vehicle.
It can be understood that when the toy vehicle passes through a curve, the head or tail of the toy vehicle easily collides with the inner side surface of the track, and the instantaneous speed of the contact point of the toy vehicle and the inner side surface of the track is rapidly reduced. If the overall speed of the toy vehicle fails to adaptively slow, the toy vehicle may easily jam in a curve or may be turned over and fly out of the track.
The brake assembly 5 is disposed on the wheel frame 100 so that the brake assembly 5 on the wheel frame 100 can be moved into contact with the inner side of the track when the toy vehicle is turning, for example, the brake assembly 5 may be disposed on the front side or the rear side of the wheel frame 100 facing the toy vehicle. When the toy car collides the inner side surface of the track, the brake component 5 can be contacted with the inner side surface of the track and reduce the running speed of the toy car, the toy car can easily turn after the speed of the toy car is reduced, and the toy car can be normally run at a speed which is increased after running through a curve.
Because the brake component 5 reduces the speed of the toy car after contacting with the obstacle, the toy car does not act when normally running on the road surface, and the influence on the normally running toy car can be avoided.
Of course, the toy vehicle with the wheel carrier 100 can be driven on other roads, such as indoors, where the toy vehicle is driven along the edge of a wall that forms an obstacle on the outside of the toy vehicle, and the brake assemblies 5 can help the toy vehicle move smoothly across a corner of a wall. For simplicity, the toy vehicle will be described as traveling on a track.
According to the wheel frame 100 for mounting on the toy vehicle of the embodiment of the invention, the brake assembly 5 capable of reducing the running speed of the toy vehicle is arranged on the wheel frame 100, so that the brake assembly 5 can contact with an obstacle when the toy vehicle encounters the obstacle and reduce the speed of the toy vehicle, the toy vehicle can turn smoothly, and the toy vehicle is prevented from being jammed or overturned when turning.
In some embodiments, as shown in fig. 1 and 6, includes: a mounting frame 2 and a wheel carrier 3.
The opposite ends of the mounting frame 2 are formed with transverse rotation shafts 21, and the wheels 1 rotate around the transverse rotation shafts 21 to drive the wheel frame 100 to move toward the driving direction of the toy vehicle. The guide wheel frame 3 is arranged on one side of the mounting frame 2 facing the head or the tail of the toy car, and the guide wheel frame 3 is provided with a guide wheel 4.
The guide wheels 4 of the toy vehicle may be in rolling contact with the obstacle wall against which the toy vehicle collides, for example, when the toy vehicle travels on a track, the guide wheels 4 are adapted to be in rolling contact with the side wall of the track, so that the guide wheels 4 may play a role of guiding, reducing the friction between the wheels 1 and the track surface when turning.
Referring to fig. 1, a brake assembly 5 is provided on at least one of the mounting frame 2 and the wheel frame 3, for example, may be installed on a side of the wheel frame 3 facing a head of the toy vehicle or a side facing a tail of the toy vehicle to reduce a traveling speed of the toy vehicle.
It is understood that the wheel frame 3 may be disposed on a side of the wheel frame 100 facing the head of the toy vehicle, the wheel frame 3 may be disposed on a side of the wheel frame 100 facing the tail of the toy vehicle, and the brake assembly 5 may be mounted on the wheel frame 3 in both cases.
If the wheel frame 3 is disposed on one side of the wheel frame 100 facing the head of the toy vehicle, the brake assembly 5 is disposed on one side of the wheel frame 3 facing the head of the toy vehicle, i.e., the brake assembly 5 is disposed on the front side of the toy vehicle, when the head of the toy vehicle touches the sidewall of the track, the brake assembly 5 can interact with the sidewall of the track to rapidly reduce the speed of the toy vehicle. If the wheel frame 3 is disposed on the side of the wheel frame 100 facing the tail of the toy vehicle, the brake assembly 5 is disposed on the side of the wheel frame 3 facing the tail of the toy vehicle, i.e., the brake assembly 5 is disposed on the tail side of the toy vehicle, when the tail of the toy vehicle touches the side wall of the track, the brake assembly 5 can act on the side wall of the track to rapidly reduce the speed of the toy vehicle.
Through set up the brake subassembly 5 that can reduce the speed of traveling of toy car on guide wheel frame 3, the toy car can reduce the speed of toy car at brake subassembly 5 when touchhing the barrier, makes the toy car turn gently, avoids the toy car card to die or the car turns over when turning.
Hereinafter, for the sake of simplicity, the structure of the brake assembly 5 and the connection structure with other components will be described by taking the example that the wheel carrier 3 is disposed on the side of the wheel carrier 100 facing the head of the toy vehicle. When the wheel frame 3 is disposed on the side of the wheel frame 100 facing the tail of the toy vehicle, the structure of the brake assembly 5 and the connection structure with other components can be derived directly from the structure of the wheel frame 3 disposed on the side of the wheel frame 100 facing the head of the toy vehicle, and the description thereof is omitted.
In some embodiments, as shown in fig. 2, the brake assembly 5 includes a brake pad 52, the brake pad 52 can contact with the rail sidewall earlier when the toy vehicle turns, the brake pad 52 is pressed and generates friction with the rail sidewall, and the kinetic energy of the toy vehicle is consumed by the deformation energy and the frictional heat generated by the brake pad 52, so as to achieve the purpose of buffering the deceleration.
The brake assembly 5 is of a very simple construction, and when the toy vehicle is travelling in a straight line, the brake assembly 5 will generally not function, avoiding interference with the normal operation of the toy vehicle.
Specifically, the brake assembly 5 includes: a movable plate 55 movable relative to the wheel frame 3, and a brake pad 52 provided on the movable plate 55.
Thus, if the side wall of the track hits the guide wheel 4 or the movable plate 55 after the toy vehicle hits the side wall of the track, the movable plate 55 may move relative to the wheel frame 3. When the movable plate 55 moves relative to the wheel frame 3, the purpose of buffering and reducing the speed can be achieved.
Optionally, an elastic member 56 is connected between the movable plate 55 and the wheel frame 3, and the elastic member 56 is configured to absorb kinetic energy and convert the kinetic energy into elastic internal energy when the movable plate 55 moves relative to the wheel frame 3, so as to further alleviate the impact force and reduce the speed of the toy vehicle.
The action principle of the buffering deceleration action of the movable plate 55 is different according to the structure and the arrangement position of the movable plate 55. For example, when the movable plate 55 is connected to the front side wall of the wheel frame 3 by the elastic member 56, if the head of the toy car collides with the rail side wall, the movable plate 55 with the brake pads 52 collides with the wall before other parts of the toy car. During a collision, the elastic member 56 is compressed by the force of the rail sidewall on the movable plate 55, and the driving speed of the toy vehicle is greatly reduced by the arrangement of the brake pad 52 and the elastic member 56. When the momentum of the toy vehicle falls, the resilient member 56 returns to its original shape and pushes the toy vehicle rearward, allowing the toy vehicle to turn around after being pulled a substantial distance from the side wall of the track. After the structure of the movable plate 55 is changed, the working principle of the movable plate 55 and the elastic member 56 is changed accordingly, which is not limited herein.
In the present invention, some of the brake pads 52 are detachably provided on the movable plate 55, thereby facilitating replacement of the brake pads 52. The brake lining 52 is glued directly to the attachment surface 553, which makes the attachment of the brake lining 52 very easy and labor-saving. After the other brake pads 52 are glued, the brake pads 52 can still be directly torn off, the brake pads 52 are detachably connected to the connecting surface 553, and the brake pads 52 are labor-saving to install and convenient to replace.
Alternatively, the brake pad 52 may be a rubber or sponge member, or the brake pad 52 may be made of other materials, for example, the brake pad 52 is made of a plastic member with high elasticity, and the like, which is not limited herein.

When the toy car passes through a curve, the guide wheel 4 of the car head contacts with the side wall of the track firstly, so that the guide wheel 4 generates pressure on the side wall of the track, and meanwhile, the side wall of the track generates counter pressure on the guide wheel 4. After the counter pressure on the guide wheel 4 is applied to the guide wheel frame 3, the guide wheel frame 3 moves relative to the movable plate 55, which is equivalent to the movable plate 55 moving towards the side wall of the track, so that the brake pad 52 on the movable plate 55 can contact with the side surface of the track, the speed of the toy car passing through the curve is reduced, and the toy car can smoothly pass through the curve.
