detailed description

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

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 Figs.

According to an embodiment of the present invention, a wheel carrier 100 for mounting on a toy vehicle is provided with a wheel 1 on the wheel carrier 100. The wheel carrier 100 is further provided with a movable brake assembly 5, and a collision obstacle on the side of the wheel carrier 100. The brake assembly 5 can move toward the obstacle and come into contact with the obstacle to reduce the running speed of the toy vehicle.

It can be understood that when the toy car passes the curve, the front or the tail of the toy car easily collides with the inner side of the track, and the instantaneous speed at the point of contact between the toy car and the inner side of the track is rapidly reduced. If the overall speed of the toy car fails to slow down adaptively, the toy car can easily get stuck in the corner, or the toy car can fly directly out of the track.

The brake assembly 5 is disposed on the wheel carrier 100, and then the brake assembly 5 on the wheel carrier 100 can be moved to contact with the inner side of the track when the toy vehicle turns, for example, the brake assembly 5 can be disposed on the front of the wheel carrier 100 facing the toy vehicle. Side or tail side. When the toy car collides with the inner side of the track, the brake assembly 5 can contact the inner side of the track and reduce the running speed of the toy car. The speed of the toy car is reduced and the turning is easy. After the curve is passed, the toy car can be lifted at a normal speed.

Since the brake assembly 5 lowers the speed of the toy vehicle after coming into contact with the obstacle, the toy vehicle does not function when it is normally driven on the road surface, and can avoid affecting the normally driven toy vehicle.

Of course, the toy car equipped with the above wheel frame 100 can also travel on other road surfaces. For example, when the toy car travels indoors, when the toy car runs along the edge of the wall, the wall also constitutes a barrier wall outside the toy car, and the brake assembly 5 can be Help the toy car to drive through the corner. In order to simplify the description, the description is made by taking the toy car on the track as an example.

According to an embodiment of the present invention, a wheel carrier 100 for mounting on a toy vehicle is provided with a brake assembly 5 on the wheel carrier 100 that can reduce the traveling speed of the toy vehicle. When the toy vehicle hits an obstacle, the brake assembly 5 can be The obstacles contact and reduce the speed of the toy car, so that the toy car can make a smooth turn, avoiding the toy car getting stuck or rolling when turning.

The guide wheel 4 of the toy car can be in rolling contact with the obstacle wall of the toy car. For example, when the toy car is traveling on the track, the guide wheel 4 is used for rolling contact with the side wall of the track, so that the guide wheel 4 can play a guiding role. To reduce the friction between the wheel 1 and the track surface during cornering.

Referring to Figure 1, the brake assembly 5 is provided on at least one of the mounting bracket 2 and the carriage 3, for example, possibly on the side of the carriage 3 facing the front of the toy vehicle or toward the side of the tail of the toy vehicle to lower The speed of the toy car.

When you get stuck or roll over.

Hereinafter, for simplification of description, the structure of the brake assembly 5 and the connection structure with other components will be described by taking the guide frame 3 on the side of the wheel carrier 100 facing the front of the toy vehicle. When the guide frame 3 is disposed on the side of the wheel carrier 100 facing the rear end of the toy vehicle, the structure of the brake assembly 5 and the connection structure with other components may be disposed by the guide frame 3 The structure of the wheel carrier 100 toward the side of the toy car head is directly derived, and the details will not be described below.

In some embodiments, as shown in FIG. 2, the brake assembly 5 includes a brake pad 52 that can be brought into contact with the rail sidewalls earlier when the toy car turns, the brake pad 52 being squeezed and rubbing against the rail sidewalls The deformation energy generated by the brake pad 52 and the friction heat generation consume the kinetic energy of the toy car, thereby achieving the purpose of buffering and slowing down.

The structure of the brake assembly 5 is very simple. When the toy car goes straight, the brake assembly 5 generally does not function to avoid interference with the normal running of the toy car.

Specifically, the brake assembly 5 includes a movable plate 55 movable relative to the guide frame 3, and the brake pad 52 is disposed on the movable plate 55.

Thus, when the toy vehicle hits the side wall of the track, if the side wall of the track hits the guide wheel 4 or the movable plate 55, the movable plate 55 may move relative to the guide frame 3. When the movable plate 55 is moved relative to the guide frame 3, the purpose of buffering and slowing down can be achieved.

Optionally, an elastic member 56 is connected between the movable plate 55 and the guide frame 3, and the elastic member 56 is disposed to absorb kinetic energy and convert into elastic internal energy when the movable plate 55 moves relative to the guide frame 3, so that the movable member can further Relieve impact and reduce the speed of the toy car.

Depending on the structure and the position of the movable plate 55, the action of the buffering and deceleration of the movable plate 55 is different. For example, when the movable panel 55 is coupled to the front side wall of the guide frame 3 via the elastic member 56, if the front face of the toy vehicle hits the side wall of the rail, the movable panel 55 with the brake pad 52 hits the wall before other parts of the toy vehicle. . During the collision, the rail side wall exerts a force on the movable plate 55 to compress the elastic member 56, and the arrangement of the brake pad 52 and the elastic member 56 causes the running speed of the toy car to be greatly reduced. When the momentum of the toy car is lowered, the elastic member 56 returns to the original shape and pushes the toy car backward, so that the toy car and the side wall of the track are pulled away to facilitate turning. After the structure of the movable plate 55 is changed, the working principle of the movable plate 55 and the elastic member 56 changes accordingly, and is not limited herein.

In the present invention, some of the brake pads 52 are detachably provided on the movable plate 55 to facilitate replacement of the brake pads 52. Some of the brake pads 52 are directly glued to the connecting surface 553, so that the brake pads 52 are connected easily and effortlessly. After the brake pad 52 is glued, the brake pad 52 can still be directly torn off, and the brake pad 52 is equivalently detachably connected to the connecting surface 553. The brake pad 52 is labor-saving and easy to replace.

Alternatively, the brake pad 52 may be a rubber member or a sponge member. Alternatively, the brake pad 52 may be made of other materials. For example, the brake pad 52 may be made of a relatively strong plastic member or the like, which is not specifically limited herein.
