Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, in particular to a rail transit simulation model, a train track and a turnout device and a turnout control thereof. BACKGROUND

[0002] There are different scales of train models and matching track models, and the train model usually transmits power and control signals through the contact between the track and the wheel. The turnout device in the track model is the most complex, which not only needs to be powered by the track, but also needs to realize the function of changing tracks. Most of the existing turnout models use the principle of electromagnet, that is, the magnetism generated by the coil power supply drives the movement of the switch structure.

[0003] During the conception and implementation of the present application, the inventors found that at least the following problems exist: the structure of the foregoing model is relatively simple, but there is no device to detect the movement of the switch to the position, and the movement distance can only be controlled by controlling the power-on time. If the power-on time is too long, the coil will heat up and be damaged, and if the power-on time is too short, it is not enough to drive to the position. Moreover, the current is relatively large at the moment of power-on, which requires a large-current electronic control device. In the existing turnout model, the fixation of the switch is mostly achieved by providing a fixed fulcrum at the root of the switch, and the driving structure drives the rail tip of the switch, so that the whole switch moves around the fulcrum at the root. In use, if the fixed fulcrum at the root of the switch is loose and the aperture becomes large, the switch will easily sway and the turnout will be unstable. Moreover, in a relatively small-scale turnout model, the fulcrum structure at the root of the switch is particularly thin, which increases the probability of damage.

[0004] The foregoing narrative is to provide general background information and does not necessarily constitute the prior art. CONTENT OF THE UTILITY MODEL

[0028] Optionally, the motor driving circuit is connected with the speed reducer motor to control the movement of the motor.

[0029] Compared with the prior art, the present application has the following advantages:

[0030] (1) The two rail roots are connected by a disc structure, which can rotate in the corresponding circular groove on the turnout base, thereby fixing the relative position of the two rails and allowing only rotation parallel to the base plane around the disc structure. This planar contact disc structure is more stable than the traditional point contact structure of the rail root, and the rail will not sway. In a small-scale turnout model, the disc structure is relatively large in size compared to the track, is not easy to wear, is easy to process, and provides a reliable rail movement structure.

[0031] (2) The turnout device is driven by a built-in micro speed reducer motor. The motor is installed inside the track base, the motor output shaft is provided with a driving rod, the driving rod drives the first movement shaft, the first movement shaft is driven by the magnetism of the magnet, the first movement shaft drives the movement of the rail tip of the rail, thereby realizing the turnout operation. The advantage is that the motor output shaft is not directly connected to the rail, but the rail is driven by the magnetic coupling between the first movement shaft and the second movement shaft. The advantage is that even if the rail has foreign matter, it will not damage the transmission structure and the motor. When the train model is squeezed, the rail will be squeezed to drive the second movement shaft, and the magnetic coupling between the second movement shaft and the first movement shaft will not cause destructive extrusion to the first movement shaft.

[0032] (3) The running range of the first movement shaft is greater than that of the second movement shaft. When the first movement shaft moves, the second movement shaft is driven by magnetic coupling. The second movement shaft drives the movement of the rail. When the rail touches the basic rail, the movement of the second movement shaft is stopped, and the first movement shaft continues to move to the position. After the first movement shaft stops at the position, the magnetic field maintains the pulling force on the second movement shaft, thereby maintaining the pressure between the rail and the basic rail, and ensuring that the rail and the basic rail are in good contact.

[0033] (4) The magnets of the first movement shaft and the second movement shaft have coupling transmission function and can provide position detection function. Through the Hall sensor on the bottom circuit board module, the positions of the first movement shaft and the second movement shaft can be detected. When the turnout moves to the position, the motor movement is turned off to protect the driving structure and the circuit. And through the positions of the first movement shaft and the second movement shaft, it can be judged whether the rail is blocked by foreign matter.

[0034] (5) The structure integrates the turnout control and the turnout structure together, has high integration degree, and is convenient for making small-scale track devices. BRIEF DESCRIPTION OF DRAWINGS
