Abstract

A locking track mechanism for a toy speeding car comprises a chassis (1) and at least a pair of locking wheels (21, 22). The locking wheels (21, 22), symmetrically set on the bottom of the chassis (1), can lock and move along a track (5) for the toy speeding car. A movable pedestal (7) of the locking wheels (21, 22) is set on the bottom of the chassis (1). A guiding wheel frame (71) is pivoted to the movable pedestal (7). The locking wheels (21, 22) are installed on the guiding wheel frame (71). The mechanism effectively ensures that the toy speeding car firmly grips the track (5) in a compact manner, so that the car can run at a high speed without getting off from the track (5). The car can be exposed completely out of the track (5), thus enhancing the velocity of the car and the viewing effect. The track (5) in the strip shape also reduces the volume of track, and can be made into various structures, to realize various styles of shuttles of the car.

Description

Toy car speed rail mechanism

The invention relates to the field of toy vehicles, in particular to a card rail mechanism of a toy vehicle. Background technique

The existing toy car for children's games is generally a four-wheel drive model. A pair of guide wheels are fixedly mounted on the front sides of the toy car. The track matched with the toy car is semi-closed, and the toy car is placed inside. The guide wheel walks along the track, and the guide wheel only contacts the track, and is only constrained by the left and right direction without being constrained by the up and down direction. Therefore, the speed of the racing car is too fast or it is easy to get off the track and fly out of the track at the corner. This will cause the car to stop and affect the car. At the same time, because the toy car travels in the track, the track width is wide and the area is large, and the track can only be changed from high to low, and it is difficult to make a complicated and varied shape, and the viewing quality is relatively poor. Moreover, due to the side panels erected on both sides of the track, the toy car is blocked, which affects the observer's line of sight and reduces the fun of play. Summary of the invention

The object of the present invention is to provide a toy that can hold a track while racing, can drive at a high speed without derailing, realize various kinds of fancy shuttles, and enhance the fun of play and the enjoyment of racing. Speed car track mechanism.

The technical solution of the present invention is achieved as follows: A toy flying car track mechanism includes a chassis, a shackle that is disposed at the bottom of the chassis and that is slidable along the track.

Wherein, the above-mentioned locating wheel can be arranged in various ways. One type is that the two accommodating wheels are symmetrically arranged on the two sides of the bottom of the chassis, respectively, and the wheel rails provided on both sides of the toy locomotive track are respectively driven along the wheel track. The card holding wheel can also be provided with two groups, the rear group holding wheel is a power wheel. In order to stabilize the card-holding track, a groove corresponding to the wheel track on the track may be provided on the rim surface of the card-carrying wheel, and the card-carrying wheel clamps the wheel track through the groove and travels on the wheel track. At least one of the above-mentioned latching wheels is a power wheel, and the power wheel is connected to the transmission mechanism.

The installation of the card wheel can be carried out in various forms. In order to facilitate the installation of the toy car on the track, the card wheel can be movably mounted on the bottom of the chassis through the movable base of the wheel, and the pivot base of the movable base of the wheel A guide wheel frame is connected, and the clamping wheel device is arranged on the guide wheel frame, and the two guide wheel frames are locked on the movable base of the clamping wheel through the pin wheel lock of the guide wheel. The card-carrying wheel movable base can also be set as a fixing device at the bottom of the chassis, and the guide wheel frame can also be set to be fixed. When the structure is installed, the guide rail can pass through the space enclosed by the two guide wheel frames of the toy car, so that the toy car card Hold on the rails and not detach.

Confirmation In order to facilitate the cooperation with the tubular track, reduce the volume and air resistance, and increase the speed of the toy car, the bottom of the chassis is provided with a concave surface that fits the shape of the guide rail and can accommodate the guide rail. The guide rail has a circular or elliptical or mushroom-shaped tubular body or a solid body.

The invention adopts the structural form of the reckoning wheel which is arranged on the bottom of the chassis of the toy flying car and which is driven along the track, thereby ensuring that the toy flying car is closely combined with the track and travels at high speed without derailing. The guide wheel frame is rotatably mounted on the chassis of the vehicle. The pin wheel lock of the guide wheel can make the two guide wheels expand at an appropriate angle, which facilitates the toy car to be hung on the track and also prevents the guide wheel from being separated from the track. Since the rim surface of the accommodating wheel is provided with a groove corresponding to the wheel rail on the track, the toy locomotive is more stable. The invention can effectively ensure that the toy speeding card holds the track at a high speed without derailing during the racing process, so that the previous toy car can be driven into the track while the car is in the track, and the toy car can be completely exposed outside the track. It improves the speed and viewing effect of the car. At the same time, the strip track not only reduces the volume of the track, but also can be made into various structural shapes to realize various kinds of fancy shuttles of the toy car, and enhance the fun of play.

The invention will now be further described with reference to the accompanying drawings. DRAWINGS
