## Background
BACKGROUND
1. Technical Field
The present invention relates to an entertainment facility. More particularly, the present invention relates to a lateral dynamic simulation device that is capable of performing in six degrees of freedom of motion with the Stewart Platform.
2. Related Art
Stewart Platform is a parallel working platform including six linear actuators, six universal joints, which join the upper and lower parts, and the platform and the base. The six linear actuators has varieties of lengths to motivate the universal joints to lead the platform on the top position in different positions and angles, thus to satisfy the inquiry for operation.
The conventional technique of applying Stewart Platform in the entertainment facility includes placing the passenger carriage above the Stewart Platform in the early stage, or reversely hang the Stewart Platform in the air and beneath the Stewart Platform. The former is an older design and the latter is designed based on the dynamic simulation for the reality and the convulsion. The dynamic force motors from the top of the carriage thus to enable the players to experience the simulation of reality.
However, the Stewart Platform is designed to position above the rear part of the carriage that substantially blocks the view to the carriage, and accordingly the surrounding layout and design. After all, such dynamic simulation for the entertainment facility not only provides the players the physical experience but also the visual and audio effects. Therefore, if the surrounding layout and design are affected, the reality simulation cannot be as good as it supposed to be.
BRIEF SUMMARY
The present invention provides a lateral dynamic simulation device including a motor mechanism. The Stewart Platform, with six degrees of freedom positioned behind the carriage is connected to a motor to enable the players to feel the reality of hanging in the air while sitting in the carriage without affecting the surrounding layout and design since the Stewart Platform is positioned at the rear side of the carriage.
The present invention provides a lateral dynamic simulation device comprising a positioning platform, a motor mechanism and a carriage. The positioning platform comprises an upright arm. The motor mechanism comprises a plurality of degrees of freedom and comprises a base and a platform and a plurality of stretchable bars connecting the base and the platform. The stretchable bars are connected to the base and the platform by the universal joint. The carriage comprises a seating space at a frontal portion for carrying passengers; and the back side of the seating space is a rear portion of the carriage. The base of the motor mechanism is fixed positioning on the arm of the platform, and the platform of the motor mechanism is securely connected to the rear portion of the carriage.

DETAILED DESCRIPTION
Referring to FIGS. 1 and 2, perspective and perspective view along another angle of the present invention, the present invention provides a lateral dynamic simulation device comprising a positioning platform 1, a motor mechanism 2 and a carriage 3.
The positioning platform 1 is for placing and fixing the dynamic simulation device on the ground, and comprises an upright arm 10 positioned erectly for positioning the motor mechanism 2. In the embodiment of the present invention, the positioning platform 1 comprises a sliding track 11 for the arm 10 to move horizontally therein.
The motor mechanism 2 comprises six degrees of freedom. Referring to FIG. 3 at the same time, the motor mechanism 2 comprises a base 20, a platform 21 and a plurality of stretchable bars 22 for connecting the base 20 and the platform 21. The stretchable bars 22, the base 20 and the platform 21 are joined by the universal joint 220. The assembly of the above elements forms the motor mechanism 2 with six degrees of freedom, for example the Stewart Platform. In the embodiment of the present invention, the base 20 and the platform 21 are formed in triangular shape and positioned alternatively for the stretchable bar 22 to connect the tips of the triangular base 20 and the platform 21. Furthermore, the base 20 and the platform 21 also comprise axial portions 200, 210 at the triangle tips, and the axial portions 220, 210 comprise axial holes 211 for receiving the universal joints 220 of the stretchable bar 22. The universal joints 220 of stretchable bars 22 comprise a protruded axle 221 to fit into the axial hole 211. The axial hole can be formed in a C-shape opening for receiving the corresponding axle 221. Every stretchable bar 22 can be a linear actuator and respectively control the length by a motor device 222. The motor device 222 can be a motor or an oil cylinder.
The carriage 3 is for carrying passengers, referring to FIG. 4, the carriage 3 comprises a space 30 at the frontal region for the passengers to sit and a back portion 31 behind the space 30 of the carriage 3. The present invention has the base 20 of the motor mechanism 2 fixed to the arm 10 of the positioning platform 1, and the platform 21 of the motor mechanism 2 is fixed to the back portion 31 of the carriage 3, thus the carriage 3 is positioned in air by the joining the motor mechanism 2 without having the frontal vision blocked by the motor mechanism 2. With the lateral position, the overall space occupation in height can be substantially reduced to benefit the surrounding layout and design.
Furthermore, referring to FIG. 4, the arm 10 of the positioning platform 1 is able to slide in the sliding track 11 and to move horizontally, thus when the arm 10 moves backward horizontally on the sliding track 11, the passengers can get on the carriage 3 easily as the carriage 3 is correspondingly positioned on the positioning platform 1. When the motor mechanism 2 is about to operate, the arm 10 moves forward horizontally by the sliding track 11 and push the carriage 3 out of the frontal side of the positioning platform 1 to allow the passengers to experience more excitement of hanging in air. Moreover, the sliding track 11 can be positioned underneath the arm 10, or positioned above the arm 10 as shown in FIG. 7. The tripping accident can be avoided when the sliding track 11 is positioned above the arm 10.
Referring to FIGS. 5 and 6, to increase the stability for the motor mechanism 2 and support the carriage 3, bars 23 can be installed along the stretchable bars 22 to join the base 20 and the platform 21. With the reinforcement of the bars 23 for supporting the base 20 and the platform 21, the motor mechanism 2 can perform more steadily in supporting the carriage 3 in the lateral position, and accordingly to upgrade the safety.
The above description is given by way of example, and not limitation. Given the above disclosure, one skilled in the art could devise variations that are within the scope and spirit of the invention disclosed herein, including configurations ways of the recessed portions and materials and/or designs of the attaching structures. Further, the various features of the embodiments disclosed herein can be used alone, or in varying combinations with each other and are not intended to be limited to the specific combination described herein.
