Description

Technical Field

[0001] This utility model relates to amusement facilities, specifically a cable-driven mechanism and a viewing device. Background Technology

[0002] Flying theaters are currently a popular amusement park ride that offers an immersive viewing experience. Riders are lifted up by their seats and off the ground, and with the help of a giant screen (especially a dome screen), they can simulate the actual sensory experience of various scenes through the motion feedback of their seats, such as passing through caves, flying at high altitudes, and climbing over mountain peaks.

[0003] Generally, these facilities consist of a base, drive components, a support frame, and seats. To allow visitors to easily sit down, the seats need to be lowered to be level with the ground. After the visitors are seated, the drive components drive the support frame to swing on the base, lifting the seats. The conventional drive method is to use a winch to pull a cable, which, in conjunction with the base, causes the support frame to swing, thus lifting the seats off the ground. However, in this winch-driven cable system, if a malfunction occurs, the cable cannot be released normally, and the release speed is difficult to control. This can easily cause the seats to hang in the air, preventing visitors from leaving their seats, resulting in significant difficulties in evacuation and prolonged waiting time. Once a malfunction occurs, it seriously affects the visitor experience. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable-driven mechanism and a viewing device that can quickly evacuate tourists and lower them to the ground when the amusement facility malfunctions, thereby improving the tourist experience.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable drive mechanism, comprising a drive mechanism and a cable, one end of which is connected to the drive mechanism and the other end to a tensioned component. The drive mechanism includes a cylinder and a piston rod connected to the cylinder. The cylinder and the piston rod are hydraulically driven. The cable is connected to the piston rod, and the cylinder drives the piston rod to extend and retract, pulling the cable. The cylinder is connected to a venting assembly for venting the pressure in the cylinder, thereby releasing the tension on the cable after the pressure is released through the venting assembly.

[0006] As a further improvement of this utility model, the cylinder body is located above and the piston rod is located below the cylinder body. The piston rod extends and retracts vertically. When the cylinder body is depressurized, the piston rod slowly descends to release the tension on the cable.

[0007] As a further improvement of this utility model, the cable is also equipped with one or more fixed pulleys, and one end of the cable corresponding to the piston rod is connected to the piston rod after the direction is adjusted by the positioning wheel.

[0008] A movie viewing device includes a base fixed to the ground, a bracket rotatably connected to the base, and a seat mounted on the bracket; the bracket is driven to rotate by a drive mechanism to take the seat away from the ground, the drive mechanism adopts any of the above-mentioned improved cable drive mechanisms, and one end of the cable corresponding to the tensioned part is used to drive the bracket, cooperating with the base to drive the bracket to rotate.

[0009] As a further improvement of this utility model, the base has a slide rail on which a moving mechanism is installed. The moving mechanism slides along the slide rail to drive the bracket to rotate. One end of the cable corresponding to the bracket is connected to the moving mechanism to pull the moving component to slide on the slide rail.

[0010] As a further improvement of this utility model, the slide rail is inclined, and the end of the seat that is away from the ground is higher than the other end. The piston rod pulls the moving mechanism on the slide rail to move upward through the cable, so as to rotate the bracket and take the seat away from the ground. When the cylinder is depressurized, the bracket is reset and the moving mechanism moves downward on the slide rail.

[0011] As a further improvement of this utility model, the base has a connector, the bracket includes a swing arm and a frame, the swing arm is rotatably connected to the connector and is used to swing in coordination with the connector to move the frame; the seat is rotatably connected to the frame, and the moving mechanism is rotatably connected to the frame to adjust the posture of the frame in coordination with the swing arm.

[0012] As a further improvement of this utility model, the seat tends to be vertical on the frame by gravity.

[0013] As a further improvement of this utility model, a pushing mechanism is provided on the frame. When the frame adjusts its posture in conjunction with the swing arm and moves the seat away from the ground, the seat abuts against the pushing mechanism and the pushing mechanism pushes the seat to change its posture.

[0014] As a further improvement of this utility model, the pushing mechanism is a cam and a driver, the driver being mounted on the frame to drive the cam to rotate or swing to push the seat.

[0015] The beneficial effects of this invention are that, during the depressurization process, the piston rod gradually releases the tension on the cable. At this time, the tensioned component can slowly recover under the action of external force or gravity. This design avoids the self-locking problem of the winch and provides a buffering effect for slow depressurization, preventing the cable from suddenly losing tension and causing damage to the tensioned component due to rapid loss of force. The depressurization component also provides a cushioning effect when lowering the seat, improving safety. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0021] Reference Figure 1-3 As shown,

[0022] A cable drive mechanism includes a drive mechanism 1 and a cable 2. One end of the cable 2 is connected to the drive mechanism 1, and the other end is connected to a tensioned component. The drive mechanism 1 includes a cylinder 11 and a piston rod 12 connected to the cylinder 11. The cylinder 11 and the piston rod 12 are hydraulically driven. The cable 2 is connected to the piston rod 12, and the cylinder 11 drives the piston rod 12 to extend and retract, pulling the cable 2. The cylinder 11 is connected to a relief assembly 3 for relieving the pressure in the cylinder 11, so as to release the tension on the cable 2 after the pressure is released by the relief assembly 3.

[0023] This solution differs from existing winches in that it features a pressure relief function. The pressure relief component 3 releases pressure from the cylinder 11, allowing the piston rod 12 to gradually release the tension on the cable 2 during the pressure relief process. At this time, the tensioned components can slowly recover under the influence of external force or gravity. This solution avoids the self-locking problem of winches and provides a buffering effect through slow pressure relief, preventing the cable 2 from suddenly losing tension and causing damage to the tensioned components due to rapid loss of force. The pressure relief component 3 is inherent in the hydraulically operated cylinder 11 and is a relatively mature technology; its use in this solution is a unique feature, providing a buffering effect and improving safety.

[0024] In this scheme, the cylinder 11 and piston rod 12 can be placed horizontally, vertically, or tilted, as long as the piston rod 12 can extend and retract to drive the cable 2. Different states can be coordinated by the fixed pulley 4 to adjust the direction of the cable 2.

[0025] The horizontal arrangement can be hidden underground and covered with a cover plate, which can provide a concealment effect and reduce the external footprint. However, if the tensile force requirement of the tensioned component is very large, sufficient lateral connection force is required to fix the cylinder 11.

[0026] However, a tilted design may require more space.

[0027] Preferably, in this design, the cylinder 11 is located at the top and the piston rod 12 is located below the cylinder 11. The piston rod 12 extends and retracts vertically. When the cylinder 11 is depressurized, the piston rod 12 slowly descends to release the tension on the cable 2.

[0028] The cylinder body 11 can be fixed by other components, and the extension of the piston rod 12 can be assisted by gravity. Longitudinal fixing is simpler than lateral fixing in providing the same connection force. Moreover, it can reduce the footprint in the longitudinal direction, and during the discharge process, the piston rod 12 can naturally extend downward by gravity. As discharge occurs, it can gradually reduce the tension on the cable 2, thereby providing a buffering function. Especially in the cases described in the background art, if a failure occurs in some scenarios, this solution can use gravity to buffer and gradually release the tension, resulting in higher safety.

[0029] In order to better cooperate with the piston rod 12, the cable 2 is also equipped with one or more fixed pulleys 4, and the end of the cable 2 corresponding to the piston rod 12 is connected to the piston rod 12 after the direction is adjusted by the positioning wheel.

[0030] After the cable 2 passes over the fixed pulley 4, its direction can be adjusted to make the cooperation between the cable 2 and the piston rod 12 more effective. This allows the end of the cable 2 corresponding to the piston rod 12 to be aligned with the extension and retraction direction of the piston rod 12 as much as possible, making the pulling force more direct. There can be multiple fixed pulleys 4, which can be adjusted according to the pulling direction of the tensioned component.

[0031] The above structure describes a cable 2 drive mechanism 1. When applied to a movie-watching device, it can form the following technical solution: a movie-watching device includes a base 51 fixed on the ground, a bracket 52 rotatably connected to the base 51, and a seat 53 mounted on the bracket 52. The bracket 52 rotates after being driven by the drive mechanism 1, so as to take the seat 53 away from the ground. The drive mechanism 1 adopts the cable 2 drive mechanism 1 as described above, and one end of the cable 2 corresponding to the tensioned part is used to drive the bracket 52, which in turn drives the bracket 52 to rotate in cooperation with the base 51.

[0032] In this solution, the bracket 52 can be driven by the cable 2. The cylinder 11 drives the piston rod 12 to retract, and the cable 2 pulls the bracket 52, allowing the bracket 52 to swing on the base 51. As the bracket 52 swings upward, the seat 53 can be lifted off the ground, thereby creating a better viewing experience in conjunction with the screen.

[0033] Since the support 52 swings upwards to lift the seat 53 off the ground, the support 52 itself has a large weight. In case of failure, the tension of the cable 2 can be gradually released by releasing the pressure of the cylinder 11 and using the downward rotation tendency of the support 52 under gravity and the downward extension tendency of the piston rod 12 under gravity. This allows the support 52 to descend slowly, and the seat 53 to descend as well, providing a rapid evacuation function. Unlike the winch used in the prior art, this solution will not have the problem of locking. This solution can quickly evacuate while also having higher safety, and will not cause safety hazards due to the support 52 suddenly losing tension.

[0034] In a further configuration, the base 51 has a slide rail 511 on which a moving mechanism 6 is mounted. The moving mechanism 6 slides along the slide rail 511 to drive the bracket 52 to rotate. One end of the cable 2 corresponding to the bracket 52 is connected to the moving mechanism 6 to pull the moving component to slide on the slide rail 511.

[0035] The cable 2 moves by pulling the moving mechanism 6, which makes the pulling smoother. Moreover, the moving mechanism 6 works in conjunction with the slide rail 511 to make the cooperation between the cable 2 and the bracket 52 more stable. It is equivalent to the moving mechanism 6 and the slide rail 511 working together as a guide to make the movement of the bracket 52 more accurate and stable.

[0036] Furthermore, as a preferred embodiment, the slide rail 511 is inclined, and the end of the seat 53 that is away from the ground is higher than the other end. The piston rod 12 pulls the moving mechanism 6 on the slide rail 511 to move upward through the cable 2, so as to rotate the bracket 52 and take the seat 53 away from the ground. When the cylinder 11 is depressurized, the bracket 52 is reset and the moving mechanism 6 moves downward on the slide rail 511.

[0037] The inclined slide rail 511 in this design allows the bracket 52 to reset better. In the reset state, due to the inclined angle, the moving mechanism 6 is less likely to move freely in its natural state, making the seat 53 more stable, making it easier for tourists to get on and off the seat 53, and also improving safety.

[0038] Furthermore, during reset, the moving mechanism 6 can slide on the slide rail 511 with the help of gravity, further assisting the extension of the piston rod 12 and allowing the bracket 52 to fall. In the absence of power, the bracket 52 can be reset quickly, improving the efficiency of tourist evacuation.

[0039] Specifically, the base 51 has a connector 512, the support 52 includes a swing arm 521 and a frame 522, the swing arm 521 is rotatably connected to the connector 512 and is used to swing in coordination with the connector 512 to move the frame 522; the seat 53 is rotatably connected to the frame 522, and the moving mechanism 6 is rotatably connected to the frame 522 to adjust the posture of the frame 522 in coordination with the swing arm 521.

[0040] As shown in the figure, the swing arm 521 is used to connect the connector 512, which is part of the base 51. It can be a column inserted into the ground and supported by the connector 512. The position of the swing arm 521 connected to the connector 512 serves as a hinge point for swinging, thereby adjusting the height of the frame 522. At the same time, it moves in conjunction with the moving mechanism 6 to adjust the angle of the frame 522. As the angle of the frame 522 is adjusted, the position of the seat 53 can be adjusted to create a better light and shadow experience, and the position of the frame 522 can be moved as far back as possible to reduce its appearance in the field of view.

[0041] Preferably, seat 53 tends to be in an upright state on frame 522 due to gravity. Using gravity to keep seat 53 upright reduces the need for power actuation, and during the descent of frame 522, seat 53 can maintain its upright position by gravity, eliminating the need for additional power to adjust its posture, making crowd control more convenient and simpler to control. In some existing technologies, the position of seat 53 requires a separate drive component, and when frame 522 descends, the drive component needs to synchronously drive seat 53 to maintain a near-vertical position. This control is cumbersome and very troublesome during crowd control, requiring constant adjustment of the matching relationship between frame 522 and seat 53.

[0042] Therefore, this solution also adopts the following method: a pushing mechanism 54 is set on the frame 522. When the frame 522 adjusts its posture in conjunction with the swing arm 521 and moves the seat 53 away from the ground, the seat 53 abuts against the pushing mechanism 54 and the pushing mechanism 54 pushes the seat 53 to change its posture.

[0043] The pushing mechanism 54 engages only after the seat 53 has moved away from the ground. Ideally, the seat 53 should be raised to its final position before engaging, and the pushing mechanism 54 should then cause the seat 53 to sway or vibrate. As the frame 522 descends, the seat 53 will approach the ground. At this point, the seat 53 will separate from the pushing mechanism 54. Without the support of the pushing mechanism 54, the seat 53 can maintain its vertical position as much as possible under gravity. It can adjust its vertical position without additional power support, simplifying the overall structure and making control easier. The seat 53 can automatically adjust its position, resulting in a better visitor experience and faster crowd control.

[0044] Preferably, the pushing mechanism 54 consists of a cam 541 and a driver 542, with the driver 542 mounted on the frame 522 for driving the cam 541 to rotate or swing to push the seat 53.

[0045] The cam 541 works in conjunction with the driver 542. The driver 542 can be controlled by directly driving the cam 541 to rotate using a motor, or by using a push rod in conjunction with a lever to make the cam 541 swing and generate a pushing effect. The cam 541 is positioned to make better contact with the seat, is easier to drive, and has a simpler structure.

[0046] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
