Detailed implementation manners

[0046] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] The embodiments of the present invention provide a car door opening and closing control mechanism, as Figure 1-8 shown, the mechanism includes a car door electric drive assembly 1, a drive belt 2, and a drive guide assembly 3;

[0048] The car door electric drive assembly 1 is arranged on the car door through a car door upper guide rail 4 and is used to provide driving power to the drive belt 2;

[0049] The drive belt 2 is wound around the car door electric drive assembly 1 and is used to drive the drive guide assembly 3 and the left car door 5 to move in the opening direction or the closing direction under the action of the car door electric drive assembly 1;

[0050] The drive guide assembly 3 is arranged on the drive belt 2 and is used to lock, close or open the right car door 6 as it moves in the opening direction or the closing direction.

[0051] As Figure 4-8As shown in the figure, the driving and guiding assembly 3 includes a guide housing 31 with a limit groove, a guide rail 32, a stabilizing frame 33, a limit block 34, a belt connector 35, and a locking assembly 36. The lower side of the guide housing 31 slides on the car door upper guide rail 4 through an intermediate fixing bracket 37. The back side of the guide housing 31 is connected to the right car door 6. The guide rail 32 is arranged between the upper and lower layers of the driving belts 2 after winding. The two ends of the belt connector 35 are respectively connected to the upper driving belt 2, and a stabilizing frame 33 cooperating with the guide rail 32 is arranged on the lower side of one end. The limit block 34 is arranged on the lower side of the inner top of the guide housing 31. A locking assembly 36 is arranged on the belt connector 35, and the locking assembly 36 is arranged in cooperation with the limit groove of the guide housing 31 to lock, close or open the right car door 6.

[0052] The upper part of the left car door 5 is connected to the driving block 22 on the lower driving belt 2 through a first connecting member 51, and the upper part of the right car door 6 is connected to the guide housing 31 on the upper driving belt 2 through a second connecting member 61.

[0053] The locking assembly 36 includes a connecting arm 361, a driving shaft 362, and a convex block 363. The convex block 363 is connected to the connecting arm 361 through a horizontally arranged driving shaft 362. The connecting arm 361 is located outside the connecting arm 361 and is arranged in the limit groove of the guide housing 31.

[0054] The convex block 363 is also connected to the connecting arm 361 through a horizontally arranged pin shaft 364.

[0055] The driving shaft 362 and the convex block 363 are integrally formed. When the convex block 363 is in a vertical state, the driving shaft 362 is located in the vertical section of the guide groove of the guide 32. At this time, the connecting arm 361 is also in a vertical state, and the belt connector 35 contacts the limit block 34 to prevent the driving belt 2 from moving further.

[0056] The connecting arm 361, the pin shaft 364, and the driving shaft 362 are fixedly connected by two screws. The pin shaft 364 is located in the pin hole of the belt connector 35, and the connecting arm 361 and the driving shaft 362 can rotate in the pin hole of the belt connector 35 along with the pin shaft 364.

[0057] When the convex block 363 is located in the inclined section of the limit groove of the guide housing 31, that is, when the left car door 5 and the right car door 6 are in the closed and locked state. When the convex block 363 rotates out of the inclined section of the limit groove of the guide housing 31 and is located in the horizontal section, that is, when the left car door 5 and the right car door 6 are in the unlocked state. Subsequently, with the horizontal movement, the left car door 5 and the right car door 6 are gradually opened.

[0058] When closed, the bump 363 enters the horizontal section of the limit groove from outside the guide housing 31, and then enters the inclined section of the limit groove of the guide housing 31, that is, the left car door 5 and the right car door 6 are in the closed and locked state again.

[0059] Furthermore, it further includes a first car door lock switch 37 and a second car door lock switch 38. The first car door lock switch 37 is arranged on the back side of the guide housing 31. There is a connection between the first car door lock switch 37 and the back side of the guide housing 31 and the right car door 6. The second car door lock switch 38 is located below the first car door lock switch 37. The first car door lock switch 37 and the second car door lock switch 38 are arranged in cooperation. At this time, the bump 363 is in the vertical section of the limit groove.

[0060] The other end of the drive shaft 362 installs the first car door lock switch 37 through a car door lock switch bracket.

[0061] The car door electric drive assembly 1 includes a motor 101, a first drive belt 102, and a drive assembly 103. Two drive assemblies 103 are arranged and are respectively located on both sides of the car door upper guide rail 4. The output ends of the two drive assemblies 103 are wound around the drive belt 2. The input end of one of the drive assemblies 103 is connected to the motor 101 through the first drive belt 102.

[0062] When the motor 101 rotates forward, the left car door 5 and the right car door 6 complete the unlocking and opening process. When the motor 101 rotates reversely, the left car door 5 and the right car door 6 complete the closing and locking process.

[0063] Furthermore, the mechanism includes a manual drive assembly 7. The manual drive assembly 7 is connected to the input end of another drive assembly 103 through a second drive belt 71.

[0064] The manual drive assembly 7 includes a manual runner 72, a third drive belt 73, and a synchronous belt pulley 74. The manual runner 72 is arranged inside the car and is connected to the synchronous belt pulley 74 through the third drive belt 73. The synchronous belt pulley 74 is connected to the input end of another drive assembly 103 through the second drive belt 71.

[0065] Match the handle with the manual runner 72. Manually rotate the handle to drive the synchronous belt pulley 74 to rotate, and then transmit the power to the drive belt 2, so that the drive belt 2 moves in the door-opening direction, and the left car door 5 and the right car door 6 are opened.

[0066] Car door status: the guide housing 31 is fixed to the middle fixed bracket 37 with guide bolts, and the two ends of the driving belt 2 are fixed to the two sides of the belt connector 35 with belt pressure plates 21 and pressure plate screws. At this time, the driving shaft 362 is located in the longitudinal groove section of the guide housing 31. Since the longitudinal groove of the guide housing 31 constrains the lateral movement of the driving shaft 362, the right car door 6 and the left car door 5 are in a locked state, and the car door lock switch bracket is in the car door lock switch on position.

[0067] Car door unlocking process: When the door opening power of the motor 101 drives the drive belt 2 to move in the door opening direction through the first transmission belt 102 and the transmission assembly 103, the drive shaft 362 is restricted by the limit groove of the guide housing 31, forcing the drive shaft 362 to move upward along the limit groove. Finally, the drive shaft 362 will move to the horizontal section of the limit groove of the guide housing 31. At this time, the connecting arm 361 and the drive shaft 362 rotate 90° clockwise, and the first car door lock switch 37 and the second car door lock switch 38 are in the disconnected state.

[0068] The protrusion 363 contacts the hall door opening and closing control mechanism as the driving shaft 362 rotates, so that the hall door opening and closing control mechanism is in an unlocked state, thereby linking the hall door to open.

[0069] Car door opening process: When the motor 101 continues to rotate in the door opening direction, the drive shaft 362 moves in the door opening direction, and the belt connector 35 enters the guide rail 32, driving the right car door 6 to move in the door opening direction at the same time. The left car door 5 moves in the door opening direction under the action of the drive block 22.

[0070] The door opening process continues until the motor stops automatically.

[0071] Car door closing process: When the motor 101 starts to rotate in the reverse direction from opening the door and stops, the drive shaft 362 starts to move in the reverse direction of closing the door. Under the constraint of the guide rail 32, the drive shaft 362 still remains in a horizontal state, the right car door 6 starts to move in the reverse direction of closing the door, and the left car door 5 starts to move in the reverse direction of closing the door under the action of the drive block 22.

[0072] Car door locking process: When the door closing process is about to end, the drive shaft 362 enters the inclined section of the limit groove of the guide housing 31, and the drive shaft 362 begins to rotate downward under the constraint of the inclined section of the limit groove until it enters the inclined section of the limit groove, and finally the belt connector 35 contacts the limit block 34 and stops moving.

[0073] When the drive shaft 362 enters the inclined section of the limit groove of the guide housing 31, the horizontal movement of the right car door 6 is restricted, and the car door is locked. At the same time, the first car door lock switch 37 and the second car door lock switch 38 are combined and connected to achieve the locking of the car door.

[0074] An embodiment of the present invention further provides a landing door opening and closing control mechanism, as Figure 9-14 shown. The mechanism includes a landing door knife assembly 8, an upper landing door guide rail 9, landing door pulleys 10, and a landing door linkage steel cable 11;

[0075] The landing door knife assembly 8 is connected to the head and tail ends of the upper landing door linkage steel cable 11, and is arranged in cooperation with the drive and guide assembly 3 of the car door opening and closing control mechanism in the above solution, and is used to drive the right landing door 14 to move in the opening direction or the closing direction under the control of the door opening and closing control mechanism;

[0076] The upper landing door guide rail 9 is arranged on the lower side of the top of the landing door bracket 12, and the left landing door 13 and the right landing door 14 are respectively arranged in cooperation on the lower side. Landing door pulleys 10 are respectively arranged on both sides of the upper side of the top of the landing door bracket 12;

[0077] The landing door linkage steel cable 11 is wound around two landing door pulleys 10, and the left landing door 13 is arranged on the lower layer of the landing door linkage steel cable 11 after winding.

[0078] The landing door opening and closing control mechanism belongs to a driven mechanism and does not have its own power source, and needs to synchronously follow the car door opening and closing control mechanism to switch states.

[0079] As Figure 11-14 shown, the landing door knife assembly 8 includes a door knife support body 81, a pair of door knives 82, a lock hook 83, and a lock hook tension spring 84. The back side of the door knife support body 81 is connected to a pair of door knives 82 through a square shaft 85. The pair of door knives 82 is arranged in cooperation with the drive and guide assembly 3 of the car door opening and closing control mechanism. One side of the lower part of the door knife support body 81 is connected to the right landing door 14, and the other side of the lower part is connected to the lock hook 83. The lock hook 83 is connected to the upper part of the front side of the door knife support body 81 through a lock hook tension spring 84.

[0080] The pair of door knives 82 includes a left door knife and a right door knife.

[0081] A door knife spring 851 is also wound around the square shaft 85.

[0082] Further, it further includes a first landing door lock switch 15 and a second landing door lock switch 16. The first landing door lock switch 15 is fixed on the door pocket 17. The door pocket 17 is connected to the landing door bracket 12 for installing the upper landing door guide rail 9. The second landing door lock switch 16 is arranged on the lower side of the lock hook 83. The first landing door lock switch 15 and the second landing door lock switch 16 are arranged in cooperation.

[0083] Hall door status: The square holes of the left and right door knives and the square shaft 85 are in loose fit. Under the elastic force of the door knife spring 851, they are pressed against the baffle of the door knife support body 81. The locking hook 83 and the door knife support body 81 are connected by a locking hook pin shaft screw. The locking hook 83 is in a horizontal position under the action of the locking hook tension spring 84. At this time, the locking hook 83 and the fixed seat of the hall door lock switch form a locked state, and the second hall door lock switch 16 and the first hall door lock switch 15 are closed and conduct electricity.

[0084] After the car door opening and closing control mechanism moves in the closing direction, the working surface of the drive shaft 362 of the car door opening and closing control mechanism gradually separates from the left and right door knives. Under the action of the locking hook tension spring 84, the locking hook 83 moves downward to the horizontal state to complete locking. At the same time, the second hall door lock switch 16 and the first hall door lock switch 15 are combined and conduct electricity.

[0085] Hall door unlocking process: When the car door opening and closing control mechanism moves in the opening direction, the first car door lock switch 37 and the second car door lock switch 38 are in the off state.

[0086] During the rotation of the drive shaft 362, it will come into contact with the left and right door knives, and push the right and left door knives to move to both sides. Since the side surface of the right door knife is in contact with the outer cylindrical surface of the pin of the locking hook 83, the locking hook 83 is lifted to unlock, and at the same time, the second hall door lock switch 16 and the first hall door lock switch 15 are disconnected.

[0087] Hall door opening process: When the car door opening and closing control mechanism continues to rotate in the opening direction, the left car door 5 and the right car door 6 move in the opening direction at the same time.

[0088] The drive shaft 362 moves in the opening direction. The left door knife exerts a clamping effect on the drive shaft 362 under the elastic force of the door knife spring 851. The drive shaft 362 moves in the opening direction, and the belt connector 35 enters the guide rail 32. The right car door 6 and the right hall door 14 move in the opening direction at the same time.

[0089] The left hall door 14 moves in the opening direction under the drive of the hall door linkage steel rope 11.

[0090] The opening process continues until the motor automatically stops.

[0091] Hall door closing process: When the car door opening and closing control mechanism rotates in the reverse direction from the opening stop, the left car door 5 and the right car door 6 start to move in the reverse closing direction.

[0092] The drive shaft 362 starts to move in the reverse closing direction. Constrained by the door knife spring 851 and the guide rail 32, the drive shaft 362 still remains horizontal. The right car door 6 and the right landing door 14 start to move in the reverse closing direction. Under the action of the drive block 22, the left car door 5 starts to move in the reverse closing direction. The left landing door 14 moves in the closing direction driven by the landing door linkage steel rope 11.

[0093] Landing door locking process: When the closing process is about to end, the car door opening and closing control mechanism locks the car door.

[0094] The working surface of the drive shaft 362 gradually separates from the left door knife and the right door knife. Under the action of the lock hook pulling spring 84, the lock hook 83 moves downward to the horizontal state to complete the locking. At the same time, the second landing door lock switch 16 and the first landing door lock switch 15 are combined and conducted.

The upper landing door guide rail 9 and the lower landing door guide rail 18 are respectively arranged on the upper and lower sides of the landing door support 12. The upper and lower ends of the left landing door 13 and the right landing door 14 are respectively connected to the upper landing door guide rail 9 and the lower landing door guide rail 18 in cooperation. The door pocket 17 is arranged on the front side of the landing door support 12.

[0098] Both the left car door 5 and the right car door 6 are composed of a plurality of door strips. Adjacent left and right door strips are hinged through a shaft structure or a shaftless structure; both the left landing door 13 and the right landing door 14 are composed of a plurality of door strips. Adjacent left and right door strips are hinged through a shaft structure or a shaftless structure.

[0099] Both the left car door 5 and the right car door 6, and both the left landing door 13 and the right landing door 14 are symmetric structures.

[0100] As Figure 16 、 17 As shown in Figures 18 and 19, each door leaf is formed by hinging multiple door bars, which are divided into two structures: shafted hinge and shaftless hinge. The two structures have the same function. The shafted hinge can improve the hinge strength, but the structure is relatively complex. The shaftless hinge has a simple structure but slightly worse hinge strength;

[0101] During the opening and closing movement of the door leaf, it can rotate and deform under the constraint of the upper and lower guide rails, without occupying the width dimension of the hoistway, thus realizing the reduction of the hoistway width dimension;

[0102] When the door leaf is in the closed state, a plane can be formed on both the inner and outer sides of the door leaf, and the gaps between adjacent door bars meet the requirements of relevant elevator standards;

[0103] Since each door bar has an independent closed cavity, the structural strength of the door bar is relatively high, and the strength of the door leaf assembly is relatively high.

[0104] Car door state: The guide housing 31 is fixed on the intermediate fixing bracket 37 with guide bolts. Both ends of the drive belt 2 are fixed on both sides of the belt connector 35 with belt pressing plates 21 and pressing plate screws. At this time, the drive shaft 362 is located in the longitudinal groove section of the guide housing 31. Due to the longitudinal groove of the guide housing 31 restricting the lateral movement of the drive shaft 362, the right car door 6 and the left car door 5 are in the locked state, and the car door lock switch bracket is in the car door lock switch conducting position.

[0105] Hall door state: The square holes of the left door knife and the right door knife are in a movable fit with the square shaft 85, and are pressed against the baffle of the door knife support body 81 under the elastic force of the door knife spring 851; The lock hook 83 is connected to the door knife support body 81 with a lock hook pin shaft screw. The lock hook 83 is in a horizontal position under the action of the lock hook tension spring 84. At this time, the lock hook 83 forms a locked state with the hall door lock switch fixing seat, and the second hall door lock switch 16 and the first hall door lock switch 15 are closed and conducted.

[0106] When the drive shaft 362 enters the inclined section of the limit groove of the guide housing 31, the drive shaft 362 starts to rotate downward under the constraint of the inclined section of the limit groove. The working surface of the drive shaft 362 gradually separates from the left door knife and the right door knife. Under the action of the lock hook tension spring 84, the lock hook 83 moves downward to the horizontal state to complete locking. At the same time, the second hall door lock switch 16 and the first hall door lock switch 15 are combined and conducted.

[0107] Unlocking process: When the door opening power of the motor 101 drives the drive belt 2 to move in the door opening direction through the first transmission belt 102 and the transmission assembly 103, the drive shaft 362 is restricted by the limit groove of the guide housing 31, forcing the drive shaft 362 to move upward along the limit groove. Finally, the drive shaft 362 will move to the horizontal section of the limit groove of the guide housing 31. At this time, the connecting arm 361 and the drive shaft 362 rotate 90° clockwise, and the first car door lock switch 37 and the second car door lock switch 38 are in the disconnected state.

[0108] The protrusion 363 contacts the hall door opening and closing control mechanism as the driving shaft 362 rotates, so that the hall door opening and closing control mechanism is in an unlocked state, thereby linking the hall door to open.

[0109] During the rotation of the drive shaft 362, it will come into contact with the left door knife and the right door knife, pushing the right door knife and the left door knife to move to both sides. Since the side surface of the right door knife contacts the outer cylindrical surface of the pin of the lock hook 83, the lock hook 83 is lifted and unlocked, and at the same time, the second hall door lock switch 16 is disconnected from the first hall door lock switch 15.

[0110] Door opening process: When the motor 101 continues to rotate in the door opening direction, the drive shaft 362 moves in the door opening direction, and the belt connector 35 enters the guide rail 32, driving the right car door 6 to move in the door opening direction at the same time. The left car door 5 moves in the door opening direction under the action of the drive block 22.

[0111] When the motor 101 continues to rotate in the door opening direction, the drive shaft 362 moves in the door opening direction, and the left door knife clamps the drive shaft 362 under the action of the elastic force of the door knife spring 851, and the drive shaft 362 moves in the door opening direction. The belt connector 35 enters the guide rail 32, and the right car door 6 and the right hall door 14 move in the door opening direction at the same time.

[0112] The left car door 5 moves in the door opening direction under the action of the driving block 22;

[0113] The left hall door 14 moves toward the door opening direction under the driving of the hall door linkage steel rope 11 .

[0114] The door opening process continues until the motor stops automatically.

[0115] Door closing process: When the motor 101 starts to rotate in the reverse direction from the door opening state, the drive shaft 362 starts to move in the reverse direction of the door closing. Under the constraint of the guide rail 32, the drive shaft 362 still remains in a horizontal state, the right car door 6 starts to move in the reverse direction of the door closing, and the left car door 5 starts to move in the reverse direction of the door closing under the action of the drive block 22.

[0116] When the motor 101 starts to rotate in the reverse direction from the door-opening stop, the drive shaft 362 starts to move reversely towards door-closing. Constrained by the door knife spring 851 and the guide rail, the drive shaft 362 still maintains a horizontal state. The right car door 6 and the right landing door 14 start to move reversely towards door-closing. Under the action of the drive block 22, the left car door 5 starts to move reversely towards door-closing. The left landing door 14 moves towards the door-closing direction driven by the landing door linkage steel rope 11.

[0117] Locking process: When the door-closing process is about to end, the drive shaft 362 enters the inclined section of the limit slot of the guide housing 31. Constrained by the inclined section of the limit slot, the drive shaft 362 starts to rotate downward until it enters the inclined section of the limit slot. Finally, the belt connector 35 contacts the limit block 34 and stops moving.

[0118] When the drive shaft 362 enters the inclined section of the limit slot of the guide housing 31, the horizontal movement of the right car door 6 is restricted, the car door is locked, and at the same time, the first car door lock switch 37 and the second car door lock switch 38 are combined and conducted to achieve the locking of the car door.

[0119] When the drive shaft 362 enters the vertical section of the limit slot of the guide housing 31, the horizontal movement of the right car door 6 is restricted, the car door is locked, and at the same time, the first car door lock switch 37 and the second car door lock switch 38 are combined and conducted.

[0120] When the drive shaft 362 enters the inclined section of the limit slot of the guide housing 31, the drive shaft 362 starts to rotate downward under the constraint of the inclined section of the limit slot. The working surface of the drive shaft 362 gradually separates from the left door knife and the right door knife. Under the action of the lock hook tension spring 84, the lock hook 83 moves downward to the horizontal state to complete the locking. At the same time, the second landing door lock switch 16 and the first landing door lock switch 15 are combined and conducted.

[0121] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
