Description

Somatosensory stand

Technical Field

The invention relates to the technical field of movable stands, in particular to a motion sensing stand capable of improving the experience of audiences in real scenes.

Background

The bleachers in the prior art are all fixed knot constructs, for the ornamental effect of further improvement film or stage performance, for the seat that provides except that the vision for spectator shakes experience system, this kind of system can provide more real physical sensation for spectator according to the change of scenario or scene to the scenario of cooperation film or stage performance reaches the purpose that promotes and vwatchs, experience effect. The prior art achieves this by rocking the seat. In the theater seat shaking system in the prior art, when the seats shake, the direction, amplitude and frequency of shaking of each seat in the theater are the same, and theoretically, shaking actions of any two seats are the same, so that the body sensations obtained by audiences at different positions are the same, which is different from a real scene greatly; for example, when a scenario is bumpy due to strong wind and strong waves on the sea, a real scene is that a certain part of the ship rises and the other part of the ship falls, and a seat shaking mode which is neat and uniform in the prior art is greatly different from the real scene, so that the improvement of the experience of audiences is influenced, and the watching and experience effects of the audiences are influenced. Chinese patent document No. CN203598497U, publication No. 5/21/2014, discloses a theater vibration system and a vibration seat, the theater vibration system includes: the audio amplifier is used for capturing input audio signals, the input audio signals are converted by the signal amplifier and the voltage conversion unit and then output to the vibrator in the vibration chair to generate vibration, and the stereo surround sound effect generated by the sound equipment is matched, so that the on-site experience of a user when watching a drama is improved. The structure has the advantages that the sound source amplifier, the signal amplifier and the voltage conversion unit are respectively and independently arranged, the structure is simple, the detection and the replacement can be respectively carried out in the aspects of maintenance, the cost is effectively reduced, the volume of the vibrator is far smaller than that of the existing vibrator, the space of the whole theater vibration system is effectively saved, and the space utilization rate is increased. However, the vibration direction, amplitude and frequency of each seat of the vibration system are the same, so that the vibration system is greatly different from a real scene, the improvement of the experience of audiences is influenced, and the viewing effect is influenced.

Disclosure of Invention

The invention aims to solve the problem that the seat shaking system in the prior art is greatly different from a real scene, and the improvement of the experience of audiences is influenced, so that the viewing effect of the audiences is influenced.

The invention adopts the technical scheme that the somatosensory stand comprises an underframe and a seat frame, wherein the seat frame is arranged above the underframe, a seat arranged in a step shape is arranged on the seat frame, a wheel groove and a swinging mechanism of the underframe are arranged on the underframe, bottom wheels used for supporting the somatosensory stand are arranged at the bottom of the underframe, the seat frame and the underframe are connected through a plurality of swinging mechanisms, each swinging mechanism comprises a supporting column, the bottom of the seat frame is hinged with the upper end of the supporting column, a roller is arranged at the lower end of the supporting column and can be matched in the wheel groove of the underframe in a rolling manner, each swinging mechanism also comprises a push-pull mechanism of the supporting column arranged on the seat frame, the push-pull mechanism is hinged on the seat frame, the front end of a push-pull rod on the push-pull mechanism is hinged with the middle part of the supporting column, when the somatosensory stand works, the swinging mechanism of the underframe drives the underframe and the seat frame to swing, the seat on the somatosensory stand swings back and forth; the push-pull mechanism of the support column pushes and pulls the support column to enable the idler wheel to roll back and forth in the wheel groove, so that the seat on the somatosensory stand integrally shakes. The stand is a steel structural member and is formed by combining an underframe and a seat frame up and down, the seat frame is connected with the underframe through a plurality of shaking mechanisms, the shaking mechanisms push and pull a support column through a push-pull rod to enable a roller at the bottom of the support column to roll in a wheel groove, so that the seat frame can be lifted or lowered relative to the underframe, and the function of the stand is similar to that of a cam. The seat frame is integrally shaken or rocked through the lifting action combination of different rocking mechanisms; the bottom frame used for supporting the seat frame can swing back and forth under the driving of the swing mechanism, so that the seat frame swings back and forth; under the combined action of the swinging mechanism of the underframe and the swinging mechanism of the seat frame, the seats on the whole stand can have bumpy feelings of ascending, descending or swinging (shaking) and the like, and the bumpy feelings are completely different from the shaking of a traditional single seat; meanwhile, the movement of the grandstand is different from the conventional (synchronous) swinging of all seats, when the grandstand moves, certain seats ascend, certain seats descend, the movement amplitude of certain seats is small, and the grand is matched with a movie picture or a performance scene, so that audiences feel a real scene with strong motion sense, such as an earthquake, a tsunami, a car bump or a ship swing. In addition, the device can be used in cooperation with stage equipment such as a fan and a smoke sprayer to achieve a better effect.

The seat of the stand is provided with water bag seat cushions for filling water, the water bag seat cushions on the same row (transverse) of seats are arranged in groups, and the water bag seat cushions in the same group are communicated through water pipes. Thus, when a certain audience on the water bag seat cushion is separated from the water bag seat cushion for a short time or the water bag seat cushion is pressed downwards due to the shaking of the stand, the water filling amount of the water bag seat cushion of the same group of audiences is directly influenced by the action of the water bag seat cushion. When a certain audience in the same group leaves the water bag seat cushion for a short time, the water bag seat cushions of other audiences in the group sink due to the outflow of water; when a certain audience in the same group squeezes the water bag seat cushion for a short time, the water bag seat cushions of other audiences in the group bulge due to the inflow of water; the irregular fluctuation can run through the whole performance process, the dynamic experience on the body can be realized through the fluctuation change of the seat cushion, and the watching pleasure of programs can be greatly improved by combining the actions of the swinging mechanism and the swinging mechanism, so that the watching effect is improved. The adjacent water bag seat cushions are connected through connecting pipes, the water bag seat cushions at the two ends are communicated with one or two water bag seat cushions at intervals through a guide pipe, and the inner diameter of the guide pipe is larger than that of the connecting pipes, so that water in the water bag seat cushions can influence other seats at a proper speed, the pipe diameter of the connecting pipe between the adjacent seats is small, namely the influence of the state change of one seat on the adjacent seat is relatively small and slow; the pipe diameter of the flow guide pipe between the water bag seat cushions which are separated by one or two seats is larger, so that the influence of the state change of a certain seat on the seats separated by one or two seats is relatively larger, and the seat has certain abruptness in action due to certain separation between the seat and the seat, so that the experience pleasure can be greatly increased.

Preferably, the somatosensory stand is provided with 10-12 rows of seats, each row of seats is provided with 20-25 seats, and the number of the seats on the whole stand is 200-300.
