The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

It should be understood that the structures, ratios, sizes, and the like shown in the drawings are only used for matching the disclosure of the present disclosure, and are not used for limiting the conditions of the present disclosure, so that the present disclosure is not limited to the technical essence, and any modifications of the structures, changes of the ratios, or adjustments of the sizes, can still fall within the scope of the present disclosure without affecting the function and the achievable purpose of the present disclosure. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description only, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention unless otherwise specified.

As shown in fig. 1 to 10, the present invention provides a cinema viewing system, which comprises a platform 1 and a vehicle 2 located on the platform 1, wherein the vehicle 2 comprises a frame 21 and a driving wheel 22 mounted on the frame 21, the platform 1 comprises a left support 11 located on the left, a left driving cylinder 12 mounted on the left support 11, a right support 13 located on the right, a right driving cylinder 14 mounted on the right support 13, and a platform body 15, one end of the left driving cylinder 12 is hinged with the left end of the platform body 15, one end of the right driving cylinder 14 is hinged with the right end of the platform body 15, the left driving cylinder 12 is fixedly connected with the left support 11, and the right driving cylinder 14 is hinged with the right support 13; the vehicle 2 is fixed to the platform body 15 of the platform 1 by the clamping mechanism 3. The operating principle of the cinema film watching system is as follows: after the vehicle 2 with the audience is driven to the setting position on the platform body 15, the vehicle 2 is fixed on the platform body 15 of the platform 1 by the clamping mechanism 3; then, the left driving cylinder 12 is used for driving the left end of the platform body 15 to lift, and the right driving cylinder 14 is used for driving the right end of the platform body 15 to lift; because the left driving cylinder 12 is fixedly connected with the left support 11, the left driving cylinder 12 cannot rotate relative to the left support 11 as a whole, and the right driving cylinder 14 is hinged with the right support 13, so that the right driving cylinder 14 can rotate relative to the right support 13 as a whole, namely, the right driving cylinder 14 can swing relative to the right support 13; therefore, when the lifting amplitude of the left end of the platform body 15 driven by the left driving cylinder 12 is consistent with the lifting amplitude of the right end of the platform body 15 driven by the right driving cylinder 14, the platform body 15 is driven to lift integrally; when the left driving cylinder 12 drives the left end of the platform body 15 to ascend and descend and the right driving cylinder 14 drives the right end of the platform body 15 to ascend and descend, the platform body 15 is driven to swing left and right, namely the right end of the platform body 15 is driven to rotate around the left end of the platform body, so that the platform body 15 is lifted and swung left and right, and the platform 1 can drive the vehicle 2 on the platform body 15 to ascend and descend and swing left and right in a matching manner with a film. Meanwhile, the platform 1 and the cinema film watching system are simple in overall structure and low in manufacturing cost.

As shown in fig. 1 and fig. 2, in the present embodiment, the platform 1 further includes a balance frame 16, the balance frame 16 includes a first connecting arm 161 and a second connecting arm 162, one end of the first connecting arm 161 is hinged to the left support 11 or the right support 13, the other end of the first connecting arm 161 is hinged to one end of the second connecting arm 162, and the other end of the second connecting arm 162 is hinged to the platform body 15; the balance bracket 16 can restrict the platform body 15 from moving in the front-rear direction with respect to the left and

right supports

11 and 13. When the platform body 15 goes up and down or swings left and right, the balance frame 16 will move along with the platform body, specifically, the included angle between the first connecting arm 161 and the second connecting arm 162 will be increased or decreased along with the platform body, so as to avoid the influence on the normal up-and-down or swing left and right of the platform body 15. Meanwhile, the balance frame 16 can limit the platform body 15 from moving in the front-rear direction relative to the left support 11 and the right support 13 by the connection relationship of the first connecting arm 161 and the left support 11 or the right support 13 and the connection relationship of the second connecting arm 162 and the platform body 15, thereby preventing the platform body 15 from applying a force in the front-rear direction, i.e., in the longitudinal direction, to the left driving cylinder 12 and the right driving cylinder 14, which may cause damage to the left driving cylinder 12 and the right driving cylinder 14. In addition, as shown in fig. 1 and fig. 2, in the present embodiment, the second connecting arm 162 is hinged to the middle of the platform body 15 in the left-right direction, that is, the hinge point of the other end of the second connecting arm 162 and the platform body 15 is located between the hinge point of the left driving cylinder 12 and the platform body 15 and the hinge point of the right driving cylinder 14 and the platform body 15. In this embodiment, one end of the first connecting arm 161 is hinged to the left support 11.

In this embodiment, the left driving cylinder 12 and the right driving cylinder 14 are both oil cylinders to ensure that the left driving cylinder 12 and the right driving cylinder 14 can both apply a large driving force to the platform body 15, thereby ensuring that the platform body 15 can be smoothly driven to ascend and descend or swing left and right. The present platform 1 also includes a hydraulic power system.

As shown in fig. 1 and fig. 2, in the present embodiment, the cylinder body of the left driving cylinder 12 is fixedly connected to the left support 11, and the piston rod of the left driving cylinder 12 is hinged to the left end of the platform body 15; the cylinder body of the right driving cylinder 14 is hinged with the right support 13, and the piston rod of the right driving cylinder 14 is hinged with the right end of the platform body 15. In this way, the cylinder body of the left drive cylinder 12 will not be able to rotate relative to the left support 11, whereas the cylinder body of the right drive cylinder 14 will be able to rotate, i.e. oscillate, relative to the right support 13. When the extension and retraction amplitude of the piston rod of the left driving cylinder 12 is consistent with that of the piston rod of the right driving cylinder 14, the platform body 15 is driven to integrally lift; when the telescopic amplitude of the piston rod of the left driving cylinder 12 is inconsistent with the telescopic amplitude of the piston rod of the right driving cylinder 14, the right end of the platform body 15 is driven to rotate around the hinged point of the platform body 15 and the left driving cylinder 12, and the right driving cylinder 14 rotates relative to the right support 13, so that the platform body 15 swings left and right.

As shown in fig. 3, in the present embodiment, there are a plurality of left driving cylinders 12, and all the left driving cylinders 12 are spaced apart in the front-rear direction, so that the force applied to the platform body 15 is increased by using the plurality of left driving cylinders 12; the right drive cylinder 14 is plural, and all the right drive cylinders 14 are spaced in the front-rear direction to increase the force applied to the platform body 15 by the plural right drive cylinders 14. Meanwhile, in the present embodiment, all the left driving cylinders 12 are connected to the synchronous shunt motor, so that the synchronous operation of all the left driving cylinders 12 is realized by using the synchronous shunt motor, thereby ensuring the synchronism of the lifting of the left end of the platform body 15. In addition, in this embodiment, all the right driving cylinders 14 are connected to the synchronous shunt motor, so that the synchronous operation of all the right driving cylinders 14 is realized by the synchronous shunt motor, thereby ensuring the synchronism of the lifting of the right end of the platform body 15. As shown in fig. 3, two left drive cylinders 12 are provided in this embodiment. The right drive cylinder 14 in this embodiment is specifically two.

In the present embodiment, the left drive cylinder 12 is only capable of performing the lifting operation, and the left drive cylinder 12 is also referred to as a lift cylinder. The right drive cylinder 14 can swing around the right support 13 and its cylinder block in addition to lifting, and the right drive cylinder 14 is also called a swing cylinder.

In this embodiment, the platform 1 is specifically located in a platform pit, the left support 11 and the right support 13 are fixed on the bottom surface of the platform pit, and the upper surface of the platform body 15 is flush with the ground. In the film watching process, after the vehicle 2 is driven to the upper part of the platform body 15 and is stopped stably, the vehicle 2 is fixed on the platform body 15 through the clamping mechanism 3; both the left and

right drive cylinders

12, 14 are in a minimum stroke state. When the movie begins to play, the piston rods of the left driving cylinder 12 and the right driving cylinder 14 realize the swinging and vertical lifting of the platform body 15 around the general axis by extending and contracting until the whole movie is finished. After the platform 1 completes the corresponding action, the left driving cylinder 12 and the right driving cylinder 14 return to the initial contraction state, and after the clamping mechanism 3 breaks the fixed connection between the vehicle 2 and the platform body 15, the vehicle 2 can be smoothly driven away.

In the embodiment, different types of tracks are arranged on the platform body 15 according to needs to allow rail vehicles to stop or trackless vehicles to stop, so that the screen clamping cinema device with two screens is very suitable for screen clamping cinema devices with two screens. The platform body 15 of the platform 1 in this embodiment can be lifted and swung left and right, and when the vehicle is used, the platform body 15 can drive the vehicle 2 located on the platform body 15 to cooperate with a film to lift up and down and swing left and right. The platform 1 is a two-degree-of-freedom dynamic platform system, can realize the left-right swinging and up-down lifting actions of the vehicle 2, and generates certain acceleration during lifting, so that an experiencer has an in-person impression. The platform 1 in this embodiment is specifically called a dynamic platform for dynamic crossing cinema. And the platform 1 has simple integral structure, low cost and convenient maintenance. In addition, the pump station of this platform 1 need not to set up on vehicle 2, and the pump station specifically sets up in special pump station room, so when this platform 1 moves, it is less to the produced noise of experience person. And because the platform 1 is a two-degree-of-freedom dynamic platform system, the platform body 15 is not allowed to move horizontally in the longitudinal direction, namely the platform body 15 is not allowed to move along the horizontal direction and the front-back direction, otherwise, the left driving cylinder 12 and the right driving cylinder 14 are damaged, the balance frame 16 is arranged, so that the platform body 15 is limited to move along the front-back direction by the balance frame 16, and the parallelogram effect between the oil cylinders is prevented.

As shown in fig. 4 to 6, in the present embodiment, the clamping mechanism 3 includes a first clamping arm 31, a second clamping arm 32, and a first telescopic arm 33 mounted on the platform 1, one end of the first telescopic arm 33 is movably connected with one end of the first clamping arm 31, the other end of the first telescopic arm 33 is movably connected with one end of the second clamping arm 32, the middle of the first clamping arm 31 is hinged with the middle of the second clamping arm 32, and the other end of the first clamping arm 31 and the other end of the second clamping arm 32 can move away from and approach each other; the clamped block 23 is mounted on the frame 21, and the other end of the first clamping arm 31 and the other end of the second clamping arm 32 are both used for contacting with the clamped block 23 of the frame 21. When the vehicle 2 needs to be fixed on the platform body 15, the first telescopic arm 33 is shortened, and drives one end of the first clamping arm 31 and one end of the second clamping arm 32 to approach each other, and the other end of the first clamping arm 31 and the other end of the second clamping arm 32 approach each other by combining the hinging of the middle part of the first clamping arm 31 and the middle part of the second clamping arm 32, until the other end of the first clamping arm 31 and the other end of the second clamping arm 32 are both tightly contacted with the clamped block 23, so that the vehicle frame 21 is fixed, the vehicle 2 is clamped, and the vehicle 2 is fixed on the platform 1; meanwhile, compared with the mode of clamping the wheels in the prior art, the clamping mechanism 3 directly clamps the frame 21 of the vehicle 2, and the reliability is higher. And the whole structure of the clamping mechanism 3 is simpler.

As shown in fig. 4 to 6, in the present embodiment, the clamping mechanism 3 further includes a second telescopic arm 34, one end of the second telescopic arm 34 is hinged to the platform 1, and the other end of the second telescopic arm 34 is hinged to one end of the first clamping arm 31. When the vehicle 2 needs to be clamped, the second telescopic arm 34 is extended or shortened to drive the first clamping arm 31 and the second clamping arm 32 to move in the left-right direction, so that the first clamping arm 31 and the second clamping arm 32 can still clamp the clamped block 23 when the vehicle 2 is in a parking position and shifts in the left-right direction. In this embodiment, one end of the second telescopic arm 34 is hinged to the platform body 15.

As shown in fig. 4 to 6, the clamping mechanism 3 in this embodiment further includes a third connecting arm 35, one end of the third connecting arm 35 is hinged to one end of the first clamping arm 31, and the other end of the third connecting arm 35 is hinged to one end of the first telescopic arm 33. Thus, one end of the first telescopic arm 33 is movably connected with one end of the first holding arm 31 through the third connecting arm 35, and when the first telescopic arm 33 extends or shortens, the third connecting arm 35 drives one end of the first holding arm 31 to move.

As shown in fig. 4 to 6, in this embodiment, the other end of the first clamping arm 31 is provided with a first hook portion 311, the other end of the second clamping arm 32 is provided with a second hook portion 321, the clamped block 23 includes an upper clamped portion 231 located above and a lower clamped portion 232 located below, the lower clamped portion 232 is fixedly connected to the upper clamped portion 231, and the width of the lower clamped portion 232 in the left-right direction is greater than the width of the upper clamped portion 231 in the left-right direction. When the vehicle 2 needs to be clamped, the first hook portion 311 of the first clamping arm 31 and the second hook portion 321 of the second clamping arm 32 approach each other until both the first hook portion 311 and the second hook portion 321 contact the clamped block 23 and are clamped by the clamped block 23, and the vehicle 2 can be effectively prevented from moving in the up-and-down direction by the matching relationship between the first hook portion 311 and the clamped block 23 and the second hook portion 321, as shown in fig. 5 and 6. The clamped block 23 in this embodiment is shaped like an inverted T. In addition, when it is necessary to release the vehicle 2, the first hook portion 311 of the first gripper arm 31 and the second hook portion 321 of the second gripper arm 32 are moved away from each other to release the gripped block 23, as shown in fig. 4 to 6. The clamped piece 23 is also referred to as a shoe of the frame 21.

Meanwhile, in this embodiment, the first telescopic boom 33 is composed of an oil cylinder, the second telescopic boom 34 is composed of an oil cylinder, a rod chamber of the first telescopic boom 33 is communicated with a rod chamber of the second telescopic boom 34, and a rod chamber of the first telescopic boom 33 is communicated with a rod chamber of the second telescopic boom 34. When the vehicle 2 is driven to a designated position above the platform 1, the rod chamber of the first telescopic arm 33 and the rod-free chamber of the second telescopic arm 34 are respectively filled with oil, that is, the first telescopic arm 33 is shortened, and the second telescopic arm 34 is extended, so as to drive the first clamping arm 31 and the second clamping arm 32 to move and clamp the frame 21.

In the present embodiment, the first telescopic arm 33 is also referred to as a clamp cylinder, and the second telescopic arm 34 is also referred to as an adjustment cylinder. The first holding arm 31, the second holding arm 32, and the third connecting arm 35 constitute a clamp. The platform 1 is specifically referred to as a platform for dynamic activity. The clamping mechanism 3 in this embodiment is specifically referred to as a dynamic cross-cinema vehicle clamping device. When the vehicle 2 runs to a specified position above the dynamic platform 1, the rod cavity of the clamping oil cylinder and the rodless cavity of the adjusting oil cylinder respectively feed oil, so that the clamping oil cylinder contracts and the adjusting oil cylinder extends, and thus, the clamping oil cylinder drives the clamp to act and clamps the vehicle frame 21; the position of the clamp along the left-right direction is adjusted by the adjusting oil cylinder so as to adapt to the error of the vehicle 2 caused by left-right deviation, namely when the parking position of the vehicle 2 deviates along the left-right direction, the clamp effectively clamps the frame 21 through corresponding adjustment.

When the vehicle 2 is not driven above the platform 1, as shown in fig. 5, the clamping mechanism 3 is in a relaxed state, the adjusting cylinder is in a minimum stroke state, the clamping cylinder is in a maximum stroke state, the clamp is opened, and the skid shoe of the vehicle 2 can normally pass through. When the vehicle 2 runs to a designated position, the sliding shoes enter the clamps, the vehicle 2 stops, the adjusting oil cylinder extends, and the clamping oil cylinder contracts at the same time until the sliding shoes of the vehicle 2 are clamped, and at the moment, the clamping device of the vehicle 2 in the cinema is in a clamping state, which is shown in figure 6. After the action is finished, the clamping device of the vehicle 2 in the cinema returns to the loosening state again, and the vehicle 2 can be driven away smoothly.

When the clamping mechanism 3 is used, the frame 21, namely the vehicle body, is directly clamped, an intermediate link is bypassed, so that the vehicle 2 does not need to select a bearing with large bearing capacity and a shaft with high strength, the manufacturing cost of the bearing and the shaft is reduced, the service life of the bearing is greatly prolonged, the reliability of the mode of directly clamping the frame 21 is higher, and the construction cost of the vehicle 2 and a cinema is lower.

The present embodiment uses the clamping mechanism 3 to clamp the frame 21 of the vehicle 2 to fix the vehicle 2 on the platform 1. In this embodiment, a plurality of sets of the clamping mechanisms 3 are mounted on the platform 1, and when in use, the plurality of sets of the clamping mechanisms 3 are used to respectively clamp a plurality of clamped blocks 23 on the frame 21, so that the vehicle 2 is firmly fixed on the platform 1.

As shown in fig. 4, in the present embodiment, there are a plurality of the held blocks 23, and all the held blocks 23 are respectively clamped by a plurality of sets of the clamping mechanisms 3, so that the carriage 21 and the vehicle 2 can be more firmly fixed at the presentation position, that is, the set position on the platform 1. In this embodiment, there are four clamped blocks 23, and the four clamped blocks 23 are located at four corners of the rectangle respectively. Four sets of clamping mechanisms 3 are mounted on the platform 1 to clamp the four clamped blocks 23, respectively, using the four sets of clamping mechanisms 3, thereby fixing the vehicle 2 on the platform 1.
