Description

Technical Field

[0001] This invention relates to the field of emergency facilities technology for experience cabins, specifically to an emergency device for sealing the door of an experience cabin and its usage method. Background Technology

[0002] With VR glasses and VR virtual reality technology, users can experience the impact of 3D technology by wearing VR glasses, making them feel as if they are in the environment, providing an immersive experience. The same technology can also be applied to meditation therapy. In order to achieve the best experience, a relatively independent and quiet simulated environment is created. The therapy cabin is designed to be closed or semi-closed. After the user enters the experience cabin and the door is closed, physical methods are used to completely relax and soothe the user's body and mind, so as to achieve the purpose of meditation therapy.

[0003] To ensure comfortable entry for users, the cabin door is relatively large. The exterior of the therapy cabin includes the door 1 and the cabin base 3, as shown below. Figure 1 As shown; to minimize the footprint, a top-and-bottom opening door structure is adopted. Chinese patent CN201710813681.7 discloses a spherical top-and-bottom opening self-service intelligent rest cabin. The cabin door is generally driven by an electric push rod. Chinese patent CN202020181881.2 discloses an electric push rod, a controller and operator for the electric push rod. The two ends of the electric push rod are respectively hinged and fixed to the cabin body and the cabin door. The electric push rod is an integral structure, which is difficult to disassemble quickly. Especially in emergency conditions (power outage or damage to the electric push rod, etc.), the cabin door is difficult to open, and the user will be locked inside the cabin, which is very likely to cause a serious personal safety accident. Summary of the Invention

[0004] This invention provides an emergency device for a sealed experience cabin door, overcoming the problem that existing experience cabin doors using electric push rods cannot be opened in emergency situations because the electric push rod is an integral structure that cannot be separated, and the cabin door is locked and difficult to open.

[0005] This invention provides the following technical solution: an emergency device for a sealed experience cabin door, comprising a cabin base, a cabin door, a movable hinge, and an electric telescopic device; the cabin base is placed horizontally on the ground, the cabin is hemispherical, and the hemispherical cavity of the cabin base faces away from the ground; the cabin door is hemispherical, with the hemispherical cavity of the cabin door facing the hemispherical cavity of the cabin base, and the hemispherical cross-section of the cabin door and the hemispherical cross-section of the cabin base are opposite to each other and mutually seal each other; symmetrical mounting grooves are provided on both sides of the inner edge of the hemispherical cross-section of the cabin door at halfway along the meshing direction between the cabin door and the cabin base, and the cabin door is connected at one end of two sets of electric telescopic devices through the symmetrically arranged mounting grooves and the use of pins, and the other ends of the two sets of electric telescopic devices are relatively horizontally and symmetrically fixed in the hemispherical cavity of the cabin base.

[0006] Driven by an electric telescopic device, the hatch opens and closes vertically via a hinge located at the highest point of the hemispherical cross-section of the hatch base. The electric telescopic device includes a lead screw, a nut, a drive motor, a sleeve, a release device, and a spring device. One end of the lead screw is connected to the drive motor near the hemispherical cavity of the hatch base. The lead screw and the nut are connected by a threaded pair. The release device includes a rotary guide sleeve and a rotary release sleeve that can rotate synchronously in the same direction around the sleeve. The rotary guide sleeve and the rotary release sleeve can only move axially. The nut is embedded in one end of the sleeve through the release device, and the other end of the sleeve is connected to the hatch. The release device is equipped with a spring device along the direction of the lead screw, which has the function of pushing or retracting the hatch.

[0007] The sleeve is hollow, and its length is sufficient to accommodate the lead screw that is screwed into the sleeve when the hatch is closed during recovery. One end of the sleeve has an installation hole for connection with the hatch, and the other end of the sleeve has symmetrical grooves along the sleeve wall. The grooves have a rectangular cross-section and are fitted with nuts that are embedded in the sleeve. The nuts include a round nut and a round nut seat. The outer diameter of the round nut is less than or equal to the inner diameter of the sleeve to facilitate insertion into the sleeve. The outer diameter of the round nut seat is the same as the outer diameter of the sleeve. The side cross-section of the nut is T-shaped. The two symmetrical sides of the round nut seat are ground flat along the tangent of the round nut. The ground flat position matches the groove of the sleeve to fit the nut into the sleeve.

[0008] Preferably, the tripping device includes a sleeve, a rotary guide sleeve, and a rotary tripping sleeve. The inner and outer diameters of the rotary guide sleeve and the rotary tripping sleeve are the same, and the inner diameter of the rotary guide sleeve and the rotary tripping sleeve is the same as the outer diameter of the sleeve. The sleeve is symmetrically provided with horizontal elongated holes perpendicular to the direction of the tube near the groove. The sleeve is provided with continuous rotating elongated holes with the same rotation angle along the direction away from the notch on the tube wall near the groove and at a distance longer than the horizontal elongated holes. One end of the rotary guide sleeve is provided with a baffle extending outward from the sleeve wall, and the other end is provided with an engagement notch A. The sleeve wall of the rotary guide sleeve is provided with through-hole rotary guide pin holes.

[0009] Preferably, one end of the rotary release bushing is provided with a pawl, which is a symmetrical set of protrusions extending into the bushing wall. This set of protrusions is used to limit the engagement and disengagement of the circular nut seat in the bushing. The other end is provided with an engagement notch B, and the bushing wall of the rotary release bushing is provided with a through-hole horizontal guide pin hole.

[0010] The rotary guide sleeve and the rotary release sleeve are engaged with each other through engagement notches A and B to form a relatively fixed integral structure. They are respectively confined within the rotary guide pin hole and the horizontal guide pin hole by the rotary guide pin and the horizontal guide pin hole. The rotary guide sleeve can make relative displacement circular motion on the sleeve within the limit range of the rotary guide pin hole, and the rotary release sleeve can make fixed-point circular motion on the sleeve within the horizontal guide pin hole.

[0011] The length of the projection of the rotating elongated hole onto the horizontal elongated hole is the same as the length of the horizontal elongated hole. The rotating guide pin hole on the rotating guide bushing is initially fixed at the end of the sleeve near the groove of the sleeve. The rotating guide pin hole on the rotating release bushing is initially fixed at the side of the horizontal elongated hole in the opposite direction of the rotation trend stroke of the rotating guide bushing.

[0012] Preferably, the engagement notch A and engagement notch B are regular or irregular and can disengage along the rotation direction, including but not limited to rectangular, triangular and arc-shaped, and the straight engagement length along the straight direction of the sleeve diameter is not less than the length of the rotating elongated hole projected onto the horizontal direction along the sleeve diameter.

[0013] Preferably, the elastic device includes a spring, an elastic push cylinder, a spring mounting base, and a release switch. The elastic push cylinder is an annular sleeve with a diameter consistent with the outer diameter of the rotary release bushing. It is annularly sleeved around the lead screw and abuts against the spring mounting base. The spring is annularly sleeved around the outer wall of the elastic push cylinder. One end of the spring is fixed to the spring mounting base near the drive motor, and the other end abuts against the push cylinder edge that extends outward perpendicular to the cylinder diameter. A pair of fixing strips extending symmetrically from the edge of the elastic push cylinder in the opposite direction to the elastic force direction are movably fixed to the spring mounting base via the release switch. The length of the elastic push cylinder diameter is between the outer diameter of the rotary release bushing and the maximum outer diameter of the upper baffle of the rotary guide bushing. The spring is in an elastically compressed energy storage state.

[0014] The instructions for using this emergency device are as follows:

[0015] a. When the hatch is operating normally and opening and closing, the drive motor rotates and drives the nut to move axially, which in turn drives the sleeve that is paired with the nut to move forward or backward. The rotating guide sleeve and the rotating release sleeve are fixed to each other on the sleeve, and the protrusion of the pawl of the rotating release sleeve wraps around the long diameter of the snap-on circular nut seat from the outside to the inside, thereby fixing the nut in the sleeve.

[0016] b. In emergency situations, the release switch can be manually or otherwise assisted by external electrical control. At this time, the spring, which is in an elastic compression and energy storage state, can be released instantly and fully extended, instantly pushing the elastic pusher. The elastic pusher triggers the baffle of the rotary guide sleeve. The rotary guide sleeve rotates and rises around the sleeve within the limit of the rotary guide pin hole. At the same time, it drives the rotary release sleeve to rotate at a fixed point within the limit of the horizontal guide pin hole and the horizontal elongated hole. The pawl on the rotary release sleeve rotates out of the groove position, the nut disengages from the rotary guide sleeve and is released, that is, the sleeve and the lead screw nut can be disengaged. The sleeve is then pushed out, and the hatch is opened.

[0017] The present invention has the following beneficial effects: The present invention achieves a one-time pin release through the lead screw and nut pair and the rotating release and compression energy storage structure that cooperates with it, and the spring release pushes the key components to disengage from the connection relationship, while pushing the sleeve open, so as to achieve the effect of emergency door opening;

[0018] 1) The electric telescopic device can be detached under emergency conditions, avoiding the inability to detach the integral electric push rod in existing technologies;

[0019] 2) The electric expansion joint is equipped with an energy storage component, which can be released under emergency conditions to achieve the effect of actively opening the door;

[0020] 3) Easy to operate. Only one operation is needed to realize both structural separation and active door opening, solving the difficulty of people performing many complex actions under emergency conditions. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Please see Figure 1 An emergency device for a sealed experience cabin door includes a cabin base 2, a cabin door 1, a movable hinge, and an electric telescopic device 3. The cabin base 2 is placed horizontally on the ground. The cabin is hemispherical, with the hemispherical cavity of the cabin base facing away from the ground. The hemispherical cross-section of the cabin base is tilted at a 45-degree angle relative to the horizontal plane. The cabin door 1 is hemispherical, with its hemispherical cavity facing the hemispherical cavity of the cabin base, and the cabin door and the cabin base are sealed together. The inner edge of the hemispherical cross-section of the cabin door 1 has symmetrical mounting grooves on both sides at halfway along the meshing direction between the cabin door and the cabin base. The cabin door 1 is connected to one end of two sets of electric telescopic devices 3 through the symmetrically arranged mounting grooves and pins. The other ends of the two sets of electric telescopic devices 3 are symmetrically and horizontally fixed in the hemispherical cavity of the cabin base 2.

[0036] Please see Figure 1-2 The hatch 1 opens and closes vertically around the movable hinge 4 at the highest point of the hemispherical cross-section of the hatch base under the drive of the electric telescopic device 3. The electric telescopic device 3 includes a lead screw 5, a nut 6, a drive motor 7, a sleeve 8, a release device, and a spring device. One end of the lead screw 5 is connected to the drive motor 7 near the hemispherical cavity of the hatch base 2. The lead screw 5 and the nut 6 are connected by a threaded pair. The release device includes a rotary guide sleeve 10 and a rotary release sleeve 11 that can rotate synchronously around the sleeve in the same direction. The rotary guide sleeve 10 and the rotary release sleeve 11 can only move axially. The nut 6 is embedded in one end of the sleeve 8 through the release device. The other end of the sleeve 8 is connected to the hatch 1. The release device is provided with a spring device that pushes towards the hatch along the direction of the lead screw.

[0037] Please see Figure 2-5The sleeve 8 is hollow, and its length is sufficient to accommodate the lead screw that screws into the sleeve when the hatch is closed during recovery. One end of the sleeve 8 has an installation hole for connection with the hatch 1. The other end of the sleeve 8 has symmetrical grooves 9 along the sleeve wall. The grooves 9 have a rectangular cross-section and are fitted with nuts 6. Nut 6 includes a circular nut 61 and a circular nut seat 62. The outer diameter of the circular nut 61 is less than or equal to the inner diameter of the sleeve 8, which facilitates insertion into the sleeve. The outer diameter of the circular nut seat 62 is the same as the outer diameter of the sleeve 8. The side cross-section of the nut 6 is T-shaped. The two symmetrical sides of the circular nut seat 62 are ground flat along the tangent of the circular nut. The ground position 63 matches the grooves 9 of the sleeve, fitting the nut 6 into the sleeve 8. When the nut is embedded in the groove of the sleeve, both rotate synchronously. Under normal use, the pawl of the rotating release sleeve presses the nut to prevent the nut from disengaging from the sleeve. At this time, the sleeve, rotating guide sleeve, rotating release sleeve and nut are relatively stationary and follow the nut in axial movement.

[0038] Please see Figure 2-7 The tripping device includes a sleeve 8, a rotary guide sleeve 10, and a rotary tripping sleeve 11. The inner and outer diameters of the rotary guide sleeve 10 and the rotary tripping sleeve 11 are the same, and the inner diameter of the rotary guide sleeve 10 and the rotary tripping sleeve 11 is the same as the outer diameter of the sleeve 8. The sleeve 8 is symmetrically provided with horizontal elongated holes 12 perpendicular to the direction of the tube near the groove. The sleeve 8 is provided with continuous rotary elongated holes 13 with the same rotation angle along the direction away from the notch on the tube wall near the groove and at a distance longer than the horizontal elongated holes. One end of the rotary guide sleeve 10 is provided with a baffle 101 extending outward from the sleeve wall, and the other end is provided with an engagement notch A102. The tube wall of the rotary guide sleeve 10 is provided with a through rotary guide pin hole 103.

[0039] One end of the rotary release bushing 11 is provided with a pawl, which is a symmetrical set of protrusions 111 extending into the bushing wall. This set of protrusions is used to limit the loosening and engagement of the circular nut seat 62 in the sleeve 8. The other end is provided with an engagement notch B112. The rotary release bushing wall is provided with a through horizontal guide pin hole 113.

[0040] The rotary guide sleeve 10 and the rotary release sleeve 11 are engaged with each other through engagement notches A102 and B112 to form a relatively fixed integral structure. They are respectively limited within the rotary guide pin hole 103 and the horizontal guide pin hole 113 by the rotary guide pin and the horizontal guide pin, respectively. The rotary guide sleeve 10 can perform relative displacement circular motion on the sleeve 8 within the limited range of the rotary guide pin hole 103, and the rotary release sleeve 11 can perform fixed-point circular motion on the sleeve 8 within the horizontal guide pin hole 113.

[0041] The length of the projection of the rotating elongated hole 13 onto the horizontal direction of the horizontal elongated hole is the same as the length of the horizontal elongated hole 12. The rotating guide pin hole 103 on the rotating guide bushing 10 is initially fixed at the end of the sleeve 8 near the sleeve groove 9 of the rotating elongated hole 13. The rotating guide pin hole 103 on the rotating release bushing 11 is initially fixed at the side of the horizontal elongated hole 12 in the opposite direction of the rotation trend stroke of the rotating guide bushing.

[0042] Both the rotary guide sleeve and the rotary release sleeve are tubular structures with similar or identical outer diameters and thicknesses. They mate with each other, with the "peak" of the rotary guide sleeve's engagement notch A embedded within the "valley" of the rotary release sleeve's engagement notch B, and the "valley" of the rotary guide sleeve covering the "peak" of the rotary release sleeve. They are coaxially nested on the sleeve, rotating synchronously, but only capable of axial translation. It should be noted that the "peak" and "valley" refer only to their mating relationship.

[0043] A horizontal guide pin is embedded in the horizontal guide pin hole of the rotary release bushing, and at the same time, the horizontal guide pin passes through the horizontal elongated hole of the sleeve and is tangentially engaged with the horizontal elongated hole. Therefore, the rotary release bushing and the sleeve can perform a certain degree of relative rotational movement, but cannot perform relative axial parallel movement.

[0044] A rotary guide pin is embedded in the rotary guide pin hole of the rotary guide bushing, and at the same time, the rotary guide pin passes through the rotary guide hole of the sleeve and is tangentially matched with the rotary elongated hole. Therefore, the rotary guide bushing and the sleeve can only perform a certain regular rotational upward or downward movement, which is consistent with the spiral pattern of the rotary elongated hole.

[0045] Please see Figure 6-7 The engagement notch A102 and engagement notch B112 are rectangular and can disengage along the rotation direction. The straight engagement length along the straight direction of the sleeve 8 diameter is greater than the length of the rotating elongated hole projected onto the horizontal direction along the sleeve 8 diameter.

[0046] Please see Figure 9 The engagement notch A102 and engagement notch B112 are triangular in the direction of rotation and can disengage.

[0047] Please see Figure 10 The engagement notch A102 and engagement notch B112 are arc-shaped along the direction of rotation and can disengage from engagement;

[0048] Please see Figure 11 The engagement notch A102 and engagement notch B112 are another type of arc-shaped disengageable engagement along the rotation direction.

[0049] Please see Figure 8The elastic device includes a spring 14, an elastic push cylinder 15, a spring mounting base 16, and a release switch 17. The elastic push cylinder 15 is an annular sleeve with a diameter that matches the outer diameter of the rotary release bushing 11. It is annularly fitted onto the lead screw 5 and abuts against the spring mounting base 16. The spring 14 is annularly fitted onto the outer wall of the sleeve of the elastic push cylinder 15. One end of the spring 14 is fixed to the spring mounting base 16 near the drive motor, and the other end abuts against the push cylinder edge 151, which extends outward perpendicular to the cylinder diameter. A pair of fixing strips 152 extend symmetrically from the elastic push cylinder edge 151 in the opposite direction to the elastic force direction and are movably fixed to the spring mounting base via the release switch. The length of the elastic push cylinder is between the outer diameter of the rotary release bushing and the maximum outer diameter of the upper baffle of the rotary guide bushing. The spring is in an elastic compression and energy storage state. The spring includes, but is not limited to, a helical spring and a gas spring.

[0050] The instructions for using this emergency device are as follows:

[0051] a. Please refer to Figure 12 When the hatch is operating normally, the drive motor rotates and drives the nut to move axially, which in turn drives the sleeve that is paired with the nut to move forward or backward. The rotary guide sleeve and the rotary release sleeve are fixed to each other on the sleeve, and the protrusion of the pawl of the rotary release sleeve wraps around the long diameter of the snap-on circular nut seat from the outside to the inside, thereby fixing the nut in the sleeve and closing together with the hatch.

[0052] b. Please refer to Figure 13 In an emergency, the spring switch can be manually or otherwise assisted by an external electronic control to release the spring, which is in an elastic compression and energy storage state. The spring can be released instantly and fully extended, pushing the elastic pusher. The elastic pusher triggers the baffle of the rotary guide sleeve. The rotary guide sleeve rotates and rises around the sleeve within the limit of the rotary guide pin hole. At the same time, it drives the rotary release sleeve to rotate at a fixed point within the limit of the horizontal guide pin hole and the horizontal elongated hole. The pawl on the rotary release sleeve rotates out of the groove position, and the nut disengages from the rotary guide sleeve and is released. That is, the sleeve and the lead screw nut can be separated. The sleeve is then pushed out, and the hatch is opened.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

In emergency situations, the release switch can be manually or otherwise assisted by external electrical control. At this time, the spring, which is in an elastic compression and energy storage state, can be released instantly and fully extended, instantly pushing the elastic pusher. The elastic pusher triggers the baffle of the rotary guide sleeve. The rotary guide sleeve rotates and rises around the sleeve within the limit of the rotary guide pin hole. At the same time, it drives the rotary release sleeve to rotate at a fixed point within the limit of the horizontal guide pin hole and the horizontal elongated hole. The pawl on the rotary release sleeve rotates out of the groove position, the nut disengages from the rotary guide sleeve and is released, that is, the sleeve and the lead screw nut can be disengaged. The sleeve is then pushed out, and the hatch is opened.
