Description

Technical Field

[0001] This invention belongs to the field of elevator technology, and in particular relates to a stepless omnidirectional door car based on clutch transmission. Background Technology

[0002] Sightseeing elevators, with their simple and beautiful appearance, large space, and good views, are widely used in scenic spots, hotels, and shopping malls. Some existing sightseeing elevators can switch between single and double passage, but they can only open doors in a fixed direction and cannot open doors on different floors in different directions. For example, a "sightseeing elevator" disclosed in Chinese patent literature (publication number CN2753703Y) includes a car connected to a traction machine at the bottom of the shaft via a guide mechanism at the top of the shaft. The traction machine is connected to a counterweight block via pulleys. Its characteristic is that the car is octagonal, with doors at 90° angles to each other on either side of any one side. The corresponding surfaces of these doors are set as viewing glass. While this invention solves the user's need for double doors and can switch between single and double passage, it can only open doors in a fixed direction and cannot open doors on different floors in different directions. Summary of the Invention

[0003] The present invention aims to overcome the problem that existing elevator cars can only open doors in a fixed direction and cannot achieve door opening in different directions on different floors, and provides a stepless omnidirectional door opening car based on clutch transmission.

[0004] A further objective of this invention is to control two of the three car walls via a moving shaft and a clutch assembly, thereby enabling the car to open doors to different floors and in different directions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A continuously variable omnidirectional door car based on clutch transmission, the car being circular and comprising a car top, car walls, and a car floor, characterized in that the car top includes a support frame and a transmission assembly, the transmission assembly includes a clutch assembly and a transmission shaft, the transmission shaft includes two moving shafts and one fixed shaft, the clutch assembly is connected to the two moving shafts, the transmission assembly also includes a central shaft, the central shaft is provided with a bevel gear, the central shaft is connected to a door opening motor, the support frame includes a drive wheel, one end of the transmission shaft is connected to the bevel gear, the other end of the transmission shaft is connected to the drive wheel, a support ring is provided above the car wall, and the drive wheel is connected to the support ring. This invention discloses a stepless omnidirectional door car based on clutch transmission. It controls the independent movement between different floors of the car wall through a clutch assembly and a transmission shaft. The opening and closing of the door is achieved by utilizing the relative position of the notch in the middle of the car wall. It can realize four door opening modes: forward single passage, reverse single passage at any angle, forward double passage, and reverse double passage at any angle. It can realize any angle, any direction, and any passage opening method on any floor, providing more possibilities for building design and improving the operating efficiency of the elevator car.

[0007] In a preferred embodiment of the present invention, the clutch assembly includes an assembly bracket and a control ring. A connecting rod is mounted on the bracket, and a pull rod is connected to the connecting rod. The pull rod is connected to a drive motor via a lead screw. The connecting rod is connected to the control ring. The assembly bracket has a movable groove, and the control ring is disposed within the movable groove. The control ring is connected to a moving shaft in the drive shaft. In the above-described clutch assembly, the drive motor drives the connecting rod and pull rod via the lead screw, causing the control ring to slide within the movable groove. The control ring drives the moving shaft. When the control ring presses against the moving shaft in the direction of the drive shaft, the moving shaft engages with the drive rod through friction, thereby achieving power transmission.

[0008] In a preferred embodiment of the present invention, the load-bearing support further includes a load-bearing steel beam and a power wheel support. There are two load-bearing steel beams arranged in a cross configuration. The power wheel support is mounted on the load-bearing steel beams. A load-bearing wheel support is also provided on the load-bearing steel beams, and a load-bearing wheel is mounted on the load-bearing wheel support. The power wheel is mounted on the power wheel support. The load-bearing wheel support is used to support the car wall, and the power wheel support is used to transmit power and support the car wall.

[0009] As a preferred embodiment of the present invention, the load-bearing steel beams can also be arranged in one of the following ways: there are three load-bearing steel beams arranged at a 120-degree angle; there are four load-bearing steel beams arranged at a 90-degree angle; or there are five load-bearing steel beams arranged at a 72-degree angle. The shape of the load-bearing steel beams can be changed according to actual needs. A cross-shaped arrangement of the load-bearing steel beams is the optimal solution, including but not limited to three beams each at a 120-degree angle (one end of each of the three load-bearing steel beams is connected to a point, and each beam is arranged at a 120-degree angle, similar to the shape of the three angle bisectors of an equilateral triangle intersecting at a point), four beams each at a 90-degree angle, and five beams each at a 72-degree angle, etc.

[0010] As a preferred embodiment of the present invention, the car wall includes an inner wall of an inner layer and a middle wall of an intermediate layer. When the elevator needs to open doors in any direction on any floor, if there is no single-pass requirement and each floor is a double-pass, a double-layer car wall is used, retaining only the inner wall and the middle wall, and removing the outer wall, further simplifying the structure.

[0011] In a preferred embodiment of the present invention, the car wall further includes an outer wall, and each layer of the car wall is provided with a bearing ring. The inner ring of the bearing ring is provided with an annular groove, and the drive wheel and the load-bearing wheel are engaged in the groove and the edge of the groove. There are three drive wheels, and the three drive wheels are respectively engaged in the corresponding annular grooves of the three layers of the car wall. The drive wheels apply force to the bearing ring of the car wall, and the groove of the bearing ring acts as a positioning track, thereby driving the car wall to rotate. The three layers of the car wall, through their relative position arrangement, can realize four door opening modes: forward single passage, reverse single passage at any angle, forward double passage, and reverse double passage at any angle.

[0012] In a preferred embodiment of the present invention, there are three load-bearing wheel brackets and one power wheel bracket. The load-bearing wheel brackets and power wheel brackets are respectively installed at the four top ends of the load-bearing steel beam, and each load-bearing wheel bracket has three load-bearing wheels. The load-bearing wheel brackets, installed on the load-bearing steel beam, are used to support the inner wall, middle wall, and outer wall, respectively; the power wheel brackets, installed on the load-bearing steel beam, are used to transmit power and support the inner wall, middle wall, and outer wall, respectively. The load-bearing wheel brackets and power wheel brackets can be adjusted according to the weight of the car door; three load-bearing wheels and one power wheel is the optimal solution.

[0013] As a preferred embodiment of the present invention, both the inner wall and the middle wall include two car walls, and the two car walls are arranged in a through-type configuration facing each other. The outer wall includes one car wall. The inner wall and the middle wall are symmetrical through-type car walls, and the outer wall is a single-piece car wall. The three car walls, through their relative arrangement, can realize four door opening modes: forward single-pass, reverse single-pass at any angle, forward double-pass, and reverse double-pass at any angle. Specifically, when the gaps in the inner wall and the middle wall correspond, and the outer wall blocks one side of the gap, forward single-pass and reverse single-pass at any angle are realized. When the gaps in the inner wall and the middle wall correspond, and the outer wall does not block either side of the gap, forward double-pass and reverse double-pass at any angle are realized. If there is no need for single-pass, the outer wall can be removed to further simplify the structure and significantly improve the operating efficiency of the elevator.

[0014] In a preferred embodiment of the present invention, there are three bevel gears, which are evenly distributed from top to bottom on the central shaft. The transmission shaft includes three transmission rods, and the moving shaft includes a first moving shaft and a second moving shaft. The three transmission rods are arranged sequentially from top to bottom. One end of each of the three transmission rods is connected to one of the three bevel gears, and the other end is connected to the first moving shaft, the fixed shaft, and the second moving shaft, respectively. The fixed shaft is located in the middle, and the moving shafts are located at the top and bottom ends. The first moving shaft, the fixed shaft, and the second moving shaft are connected to the power wheel. The moving shaft can be connected to and disconnected from the transmission rods through a clutch assembly. By controlling two of the three car walls through the moving shaft and the clutch assembly, the opposite-floor, opposite-direction door opening of the car can be achieved.

[0015] Therefore, the present invention has the following beneficial effects: The present invention provides a stepless omnidirectional door opening car based on clutch transmission, which controls the independent movement between different layers of the car wall through the clutch assembly and the transmission shaft. It realizes door opening and closing by utilizing the relative position of the notch in the middle of the car wall. It can realize four door opening modes: forward single passage, reverse single passage at any angle, forward double passage, and reverse double passage at any angle. It can realize door opening methods of any angle, any direction, and any passage on any floor, providing more possibilities for building design, and improving the operating efficiency of the elevator car.

[0023] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0024] A continuously variable omnidirectional door car based on clutch transmission is disclosed. The car is circular and includes a car top 1, a car wall 2, and a car bottom 3. The car top 1 includes a support bracket 4 and a transmission assembly 5. The transmission assembly 5 includes a clutch assembly 11 and a transmission shaft 12. The transmission shaft 12 includes two moving shafts and a fixed shaft 23. The clutch assembly 11 is connected to the two moving shafts. A bevel gear 15 is provided on the central shaft 13. One end of the transmission shaft 12 is connected to the bevel gear 15. The central shaft 13 is connected to a door opening motor 14. The support bracket 4 includes a power wheel 10. The other end of the transmission shaft 12 is connected to the power wheel 10. A support ring 29 is provided above the car wall 2. The power wheel 10 is connected to the support ring 29.

[0025] The clutch assembly 11 includes an assembly bracket 16 and a control ring 21. A connecting rod 20 is mounted on the bracket, and the connecting rod 20 is connected to a pull rod 19. The pull rod 19 is connected to a drive motor 17 via a lead screw 18. The connecting rod 20 is connected to the control ring 21. The assembly bracket 16 has a moving groove, and the control ring 21 is located within the moving groove. The control ring 21 is connected to the moving shaft in the drive shaft 12. In the clutch assembly 11 described above, the drive motor 17 drives the connecting rod 20 and the pull rod 19 via the lead screw 18, causing the control ring 21 to slide within the moving groove. The control ring 21 drives the moving shaft. When the control ring 21 presses against the moving shaft in the direction of the drive shaft, the moving shaft engages with the drive rod 33 through friction, thus achieving power transmission.

[0026] The load-bearing support 4 also includes a load-bearing steel beam 6 and a power wheel support 9. There are two load-bearing steel beams 6, arranged in a cross shape. The power wheel support 9 is installed on the load-bearing steel beam 6. The load-bearing steel beam 6 is also equipped with a load-bearing wheel support 7, on which load-bearing wheels 8 are installed. The power wheel 10 is installed on the power wheel support 9. The load-bearing wheel support 7 is used to support the car wall 2, and the power wheel support 9 is used to transmit power and support the car wall 2.

[0027] The load-bearing steel beams 6 can also be configured in one of the following ways: there are three load-bearing steel beams 6 arranged at a 120-degree angle; there are four load-bearing steel beams 6 arranged at a 90-degree angle; or there are five load-bearing steel beams 6 arranged at a 72-degree angle. The shape of the load-bearing steel beams 6 can be changed according to actual needs. A cross-shaped arrangement of the load-bearing steel beams 6 is the optimal solution, including but not limited to three beams at 120 degrees each (one end of the three load-bearing steel beams is connected to a point, and each beam is arranged at a 120-degree angle, similar to the shape of the three angle bisectors of an equilateral triangle intersecting at a point), four beams at 90 degrees each, and five beams at 72 degrees each, etc.

[0028] The car wall 2 can have two layers, including an inner wall 27 and a middle wall 26. Each layer of the car wall 2 is equipped with a load-bearing ring 29, and the inner ring of the load-bearing ring 29 has a track. The drive wheel 10 is engaged with the corresponding track of the load-bearing ring 29 of the two layers of car walls 2. The drive wheel 10 applies force to the load-bearing ring 29 of the car wall 2, thereby driving the car wall 2 to rotate. The two layers of car walls 2 can achieve forward double passage and reverse double passage at any angle by their relative positions.

[0029] The car wall 2 can have three layers: an outer wall 25, an inner wall 27, and a middle wall 26. Each layer of the car wall 2 is equipped with a load-bearing ring 29, and the inner ring of the load-bearing ring 29 has a track. There are three drive wheels 10, which are respectively engaged on the tracks of the corresponding load-bearing rings 29 of the three layers of the car wall 2. The drive wheels 10 apply force to the load-bearing rings 29 of the car wall 2, thereby driving the car wall 2 to rotate. Through the arrangement of their relative positions, the three layers of the car wall 2 can realize four door opening modes: forward single passage, reverse single passage at any angle, forward double passage, and reverse double passage at any angle.

[0030] There are three load-bearing wheel brackets 7 and one power wheel bracket 9. The load-bearing wheel brackets 7 and power wheel brackets 9 are respectively installed at the four top ends of the load-bearing steel beam 6. Each load-bearing wheel bracket 7 is equipped with three load-bearing wheels 8. The load-bearing wheel brackets 7 are installed on the load-bearing steel beam 6 and are used to support the inner wall 27, the middle wall 26 and the outer wall 25 respectively; the power wheel brackets 9 are installed on the load-bearing steel beam 6 and are used to transmit power and support the inner wall 27, the middle wall 26 and the outer wall 25 respectively.

[0031] Both the inner wall 27 and the middle wall 26 contain two car wall pieces 2, which are arranged in a through-type configuration. The outer wall 25 contains one car wall piece 2. The inner wall 27 and the middle wall 26 are symmetrical through-type car walls, while the outer wall 25 is a single-piece car wall. The three car walls 2, through their relative arrangement, can achieve four door opening modes: forward single-pass, reverse single-pass at any angle, forward double-pass, and reverse double-pass at any angle. Specifically, when the gaps in the inner wall 27 and the middle wall 26 correspond, and the outer wall 25 blocks one side of the gap, forward single-pass and reverse single-pass at any angle are achieved. When the gaps in the inner wall 27 and the middle wall 26 correspond, and the outer wall 25 does not block either side of the gap, forward double-pass and reverse double-pass at any angle are achieved. If there is no need for single-pass operation, the outer wall 25 can be removed to further simplify the structure and significantly improve the elevator's operating efficiency.

[0032] The size of a single car wall can be determined according to the actual operation of the elevator and the needs of the building. In the double car wall of inner wall 27 and middle wall 26, the two single car walls are symmetrically distributed. Theoretically, the angle of a single car wall is between 90 degrees and 180 degrees. When the angle of a single car wall is 90 degrees, the car cannot be sealed. When it is 150-180 degrees, it will cause inconvenience in getting in and out. Therefore, the optimal angle of a single car wall in the double car wall of inner wall and middle wall is 100-130 degrees.

[0033] There are three bevel gears 15, evenly distributed from top to bottom on the central shaft 13. The transmission shaft includes three transmission rods 33, and the moving shaft includes a first moving shaft 22 and a second moving shaft 24. The three transmission rods 33 are arranged sequentially from top to bottom as an upper transmission rod, a middle transmission rod, and a lower transmission rod. One end of each of the three transmission rods 33 is connected to one of the three bevel gears 15, and the other end is connected to the first moving shaft 22, the fixed shaft 23, and the second moving shaft 24, respectively. The fixed shaft 23 is located in the middle, and the moving shafts are located at the top and bottom ends. The first moving shaft 22, the fixed shaft 23, and the second moving shaft 24 are connected to the power wheel. The moving shaft can be connected to and disconnected from the transmission rods 33 through the clutch assembly 11. By controlling two of the three car walls through the moving shaft and the clutch assembly 33, the opposite-floor and opposite-direction opening of the car doors can be achieved.

[0034] The car wall 2 also includes a liner and a boot liner 32. The liner includes an upper liner 28 and a lower liner 31, and the boot liner 32 is located below the lower liner 31.

[0035] The connection method of each component of the car wall 2 and the transmission assembly 5 is as follows: outer wall 25 - power wheel 10 - first moving shaft 22 - clutch assembly 11 - upper transmission rod - bevel gear 15; middle wall 26 - power wheel 10 - fixed shaft 23 - middle transmission rod - bevel gear 15; inner wall 27 - power wheel 10 - second moving shaft 24 - clutch assembly 11 - lower transmission rod - bevel gear 15.

[0036] In this embodiment, such as Figure 1The illustrated car features a continuously variable omnidirectional door opening mechanism based on clutch transmission, comprising a car top 1, car walls 2, and car floor 3. For example... Figure 2 As shown, the aforementioned car roof 1 includes a load-bearing bracket 4 and a transmission assembly 5, used to support the door opening transmission system and hang the car wall 2; the aforementioned load-bearing bracket 4 includes a load-bearing steel beam 6, a load-bearing wheel bracket 7, a load-bearing wheel 8, a power wheel bracket 9, and a power wheel 10. Figure 3 As shown, the aforementioned transmission assembly 5 includes a clutch assembly 11, a drive shaft 12, a central shaft 13, and a door opening motor 14. Figure 4 As shown, the clutch assembly 11 includes an assembly bracket 16, a drive motor 17, a pull rod 19, a connecting rod 20, a control ring 21, a fixed shaft 23, and a moving shaft. The moving shaft includes a first moving shaft 22 and a second moving shaft 24. There are two of each of the drive motor 17, pull rod 19, connecting rod 20, and control ring 21, each controlling one moving shaft. Figure 5 As shown, the aforementioned car wall 2 includes an inner wall 27, a middle wall 26, and an outer wall 25, simultaneously functioning as both a car wall and a car door. The inner wall 27, middle wall 26, and outer wall 25 each include an upper circular support ring 29, a glass car wall 30, upper and lower lining plates 31, and a bottom shoe liner 32. The clutch assembly 11 has a drive motor 17 at both the top and bottom. The upper and lower drive shafts operate on the same principle and have the same structure, differing only in the arrangement of the drive motors 17. This results in the upper motor pulling the connecting rod and lever, driving the control ring, and disconnecting the power; the lower motor pushes the connecting rod and lever, driving the control ring, and disconnecting the power. The upper first moving shaft 22 drives the outer wall 25, the middle fixed shaft 23 drives the middle wall 26, and the lower second moving shaft 24 drives the inner wall 27. The upper first moving shaft 22 and the lower second moving shaft 24 are connected by a clutch device, which can disconnect the power transmission when necessary. The middle fixed shaft 23 has no clutch device and is directly driven by the door opening motor 14.

[0037] A continuously variable omnidirectional door car based on clutch transmission includes a car top 1, car walls 2, and car floor 3. The car top 1 includes a support bracket 4 and a transmission assembly 5, which are used to support the door opening transmission system and hang the car walls 2.

[0038] The aforementioned support bracket 4 includes two load-bearing steel beams 6, a load-bearing wheel bracket 7, a load-bearing wheel 8, a power wheel bracket 9, and a power wheel 10. The aforementioned transmission assembly 5 includes a clutch assembly 11, a drive shaft 12, a central shaft 13, and a door opening motor 14; the aforementioned drive shaft 12 has three shafts, upper, middle, and lower, each controlling one ring of the car wall, of which the upper and lower two are driving shafts, connected and controlling the outer and inner car walls through the clutch assembly 11, and the middle shaft is a fixed shaft, directly connected and controlling the middle car wall.

[0039] The included angle between the two load-bearing steel beams 6 mentioned above is not limited to 90 degrees, but the effect is best when the included angle is 90 degrees.

[0040] There are three load-bearing wheel supports 7, which are respectively arranged at the 3 o'clock, 6 o'clock, and 9 o'clock positions of the circular car. The load-bearing wheel supports 7 are installed on the load-bearing steel beam 6 and are used to support the inner wall 27, the middle wall 26, and the outer wall 25.

[0041] There is one drive wheel bracket 9, which is located at the 12 o'clock position of the circular car. The drive wheel bracket 9 is installed on the supporting steel beam 6 and is used to transmit power and support the inner wall 27, the middle wall 26 and the outer wall 25.

[0042] The clutch assembly 11 includes an assembly bracket 16, a drive motor 17, a pull rod 19, a connecting rod 20, a control ring 21, a fixed shaft 23, and a moving shaft. When the clutch assembly 11 is working, the motor pulls the pull rod 19 through the lead screw 18, the pull rod 19 drives the connecting rod 20 to move, and the connecting rod 20 drives the control ring 21 to move along the groove on the assembly bracket 16, thereby causing the moving shaft to press against or move away from the central shaft 13, realizing the transmission and disconnection of axial force.

[0043] The aforementioned door opening motor 14 drives the central shaft 13, which has three bevel gears 15, corresponding to the three drive shafts 12 respectively.

[0044] The aforementioned drive wheel 10 has a toothed or roughened surface.

[0045] The aforementioned car wall 2 includes an inner wall 27, a middle wall 26, and an outer wall 25, which simultaneously functions as a car wall and a car door. The inner wall 27, middle wall 26, and outer wall 25 each include an upper circular support ring 29, a glass car wall 30, upper and lower lining plates 31, and a bottom boot liner 32. The inner ring of the circular support ring 29 has an annular groove, in which the drive wheel 10 and the load-bearing wheel 8 are engaged, and at the edge of the groove, to secure the drive wheel 10. The load-bearing wheel 8 moves within the groove.

[0046] like Figure 6 As shown, the aforementioned car wall 2 includes an inner wall 27, a middle wall 26, and an outer wall 25. The inner wall 27 and middle wall 26 are symmetrical, continuous car walls, while the outer wall 25 is a single-piece car wall. The three layers of car walls 2, through their relative arrangement, can achieve four door opening modes: forward single-pass, reverse single-pass at any angle, forward double-pass, and reverse double-pass at any angle. Specifically, when the gaps in the inner wall 27 and middle wall 26 correspond, and the outer wall 25 blocks one side of the gap, forward single-pass and reverse single-pass at any angle are achieved. When the gaps in the inner wall 27 and middle wall 26 correspond, and the outer wall 25 does not block either side of the gap, forward double-pass and reverse double-pass at any angle are achieved. If there is no need for single-pass operation, the outer wall 25 can be removed, further simplifying the structure and significantly improving the elevator's operating efficiency.

[0047] like Figure 6 As shown, in this embodiment, the dynamic control process for the car to achieve forward double-passage is given: First, the car is in the closed state, such as... Figure 6-1 As shown, at this time, the inner wall 27 and the middle wall 26 of the car enclose the car in a closed state, and the outer wall 25 is in the same direction as one of the inner walls 27. At this time, the transmission motor 17 in the clutch assembly 11 is activated, so that the first moving shaft 22 is connected to the upper transmission rod, and the second moving shaft 24 is disconnected from the lower transmission rod. At this time, the door opening motor 14 in the transmission assembly 5 is activated, driving the central shaft 13 to rotate, thereby driving the first moving shaft 22 and the fixed shaft 23 to rotate, thereby driving the outer wall 25 and the inner wall 27 of the car to rotate 90 degrees clockwise at the same time, so as to achieve the desired effect. Figure 6-2 The car is shown in a forward two-way open state.

[0048] like Figure 6 As shown in the figure, in this embodiment, the dynamic control process for the car to achieve forward one-way passage is given: First, the car is in the closed state, such as... Figure 6-1 As shown, at this time, the inner wall 27 and the middle wall 26 of the car enclose the car in a closed state, and the outer wall 25 is in the same direction as one of the inner walls 27. At this time, the transmission motor 17 in the clutch assembly 11 is activated, so that the first moving shaft 22 and the second moving shaft 24 are connected to the upper and lower transmission rods. At this time, the door opening motor 14 in the transmission assembly 5 is activated, driving the central shaft 13 to rotate, thereby driving the first moving shaft 22, the second moving shaft 24 and the fixed shaft 23 to rotate, thereby driving the inner wall 27, the middle wall 26 and the outer wall 25 of the car to rotate 90 degrees clockwise. Then, the transmission motor 17 in the clutch assembly 11 is activated, so that the second moving shaft 24 is disengaged from the lower transmission rod. At this time, the door opening motor 14 in the transmission assembly 5 is activated, driving the central shaft 13 to rotate, thereby driving the first moving shaft 22 and the fixed shaft 23 to rotate, thereby driving the middle wall 26 and the outer wall 25 of the car to rotate 90 degrees counterclockwise, achieving the desired effect. Figure 6-3 The image shows the car in a forward single-pass state.

[0049] like Figure 6 As shown in the figure, in this embodiment, the dynamic control process for the car to achieve dual-direction passage is given: First, the car is in the closed state, such as... Figure 6-1 As shown, at this time, the inner wall 27 and the middle wall 26 of the car enclose the car in a closed state, and the outer wall 25 is in the same direction as one of the inner walls 27. At this time, the transmission motor 17 in the clutch assembly 11 is activated, causing the first moving shaft 22 and the second moving shaft 24 to move away from the upper and lower transmission rods and disconnect. At this time, the door opening motor 14 in the transmission assembly 5 is activated, driving the central shaft 13 to rotate, thereby driving the fixed shaft 23 to rotate, thereby driving the middle wall 26 of the car to rotate 90 degrees clockwise / counterclockwise, and then achieving the desired effect. Figure 6-4 The car is shown in a state of dual-direction operation.

[0050] like Figure 6 As shown in the figure, in this embodiment, the dynamic control process for the car to achieve one-way passage in opposite directions is given: First, the car is in the closed state, such as... Figure 6-1As shown, at this time, the inner wall 27 and the middle wall 26 of the car enclose the car in a closed state, and the outer wall 25 is in the same direction as one of the inner walls 27. At this time, the transmission motor 17 in the clutch assembly 11 is activated, causing the second moving shaft 24 to move away from and disconnect from the lower transmission rod, and the first moving shaft 22 to connect with the upper transmission rod. At this time, the door opening motor 14 in the transmission assembly 5 is activated, driving the central shaft 13 to rotate, thereby driving the first moving shaft 22 and the fixed shaft 23 to rotate, thereby driving the outer wall 25 and the middle wall 26 of the car to rotate 90 degrees clockwise, achieving the desired effect. Figure 6-5 The image shows the car in a single-direction, opposite-direction state.

[0051] After the car of the present invention achieves both double-passage and single-passage, it can achieve both double-passage and single-passage at any angle by simultaneously driving the three layers of car walls to rotate synchronously.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the scope of protection of the present invention.
