[0002] Electric double-hinged swing doors are motor-driven, allowing both doors to open and close. They are commonly used as entrances and exits in places like shopping malls, hotels, residences, and villa elevators. Some doors use a single motor to open and close both doors, while others use two motors, each driving one door. Whether driven by a single or dual motor, a synchronization control device is installed between the two doors to ensure synchronized opening and closing. However, existing synchronization control devices for electric double-hinged swing doors are ineffective. If one or both doors are subjected to external forces, the synchronization between the two doors deteriorates. Furthermore, the synchronization control device is complex in structure and requires a relatively high amount of power to maintain synchronization, resulting in high energy consumption and low energy consumption. Accidents can easily occur, and restoring synchronization is difficult, impacting the effectiveness of electric double-hinged swing doors. Summary of the Invention

A synchronization device 8 consisting of a left wheel 81, a right wheel 82 and a transmission chain 83 is provided between the left transmission shaft 5 and the right transmission shaft 7. The left wheel 81 is installed on the left transmission shaft 5, and the right wheel 82 is installed on the right transmission shaft 7. The transmission chain 83 is connected between the left wheel 81 and the right wheel 82, driving the left door 1 and the right door 2 to open and close synchronously. A reduction motor 9 with an output shaft connected to the left transmission shaft 5 or the right transmission shaft 7 is provided on the door frame 3.

[0008] Example 2, as Figure 2 As shown, the difference from the first embodiment is that the door frame 3 is provided with two reduction motors 9 whose output shafts are connected to the left transmission shaft 5 and the right transmission shaft 7 respectively.

[0009] The left door shaft 11 is arranged on the left side of the left door 1 along the up and down directions. The upper and lower ends of the left door shaft 11 are respectively rotated with the door frame 3 to hinge the left door 1 on the door frame 3. The upper end of the left door shaft 11 extends to the top of the door frame 3 and is fixedly connected to the output part of the left electromagnetic clutch 4.

[0010] The right door shaft 21 is arranged on the right side of the right door 2 along the up and down directions. The upper and lower ends of the right door shaft 21 are respectively rotated with the door frame 3 to hinge the right door 2 on the door frame 3. The upper end of the right door shaft 21 extends to the top of the door frame 3 and is fixedly connected to the output part of the right electromagnetic clutch 6.

[0011] The left wheel 81 and the right wheel 82 of the synchronization device 8 are synchronization wheels (such as Figure 1 、 Figure 2 As shown, the transmission chain 83 consists of a double-sided toothed synchronous belt 84 and a rectangular bridge 85. The two ends of the synchronous belt 84 are connected by the bridge 85, forming a figure-8 connection between the left and right wheels 81 and 82. The bridge 85 is located at the intersection of the figure-8, and the synchronous belt 84 passes through the square hole of the bridge 85 to avoid interference at the intersection. The teeth on one side of the double-sided toothed synchronous belt 84 mate with the left wheel 81. After passing through the square hole of the bridge 85, the teeth on the back side mate with the right wheel 82.

[0012] The bridge device 85 is composed of a left connecting member 86, a right connecting member 87, an upper connecting rod 88 and a lower connecting rod 89. The left connecting member 86 and the right connecting member 87 are respectively connected to the two ends of the synchronous belt 84. The upper connecting rod 88 and the lower connecting rod 89 are respectively located above and below the synchronous belt 84 at the intersection position. The right ends are fixedly connected to the right connecting member 87, and the left ends pass through the connecting rod holes on the left connecting member 86 and slide with the left connecting member 86. The upper connecting rod 88 and the lower connecting rod 89 extending to the left side of the left connecting member 86 are respectively provided with compression springs 90, and the left ends of the upper connecting rod 88 and the lower connecting rod 89 located on the left side of the compression spring 90 are respectively installed with nuts 91 through threads.

[0013] Alternatively, the left ends of the upper connecting rod 88 and the lower connecting rod 89 are connected to the left connecting member 86 via tension springs, which can also tighten the transmission chain belt 83.

[0014] The left wheel 81 and the right wheel 82 of the synchronization device 8 are respectively sprockets (such as Figure 3 As shown, the transmission chain 83 consists of a roller chain 92 and a rectangular bridge 85. The roller chain 92 is connected at both ends by the bridge 85, forming a figure-eight connection between the left and right wheels 81 and 82. The bridge 85 is located at the intersection of the figure-eight, and the roller chain 92 passes through the square hole of the bridge 85 to avoid interference at the intersection. One side of the roller chain 92 engages with the left wheel 81. After passing through the square hole of the bridge 85, the back side engages with the right wheel 82.

[0015] The bridge device 85 is composed of a left connecting member 86, a right connecting member 87, an upper connecting rod 88 and a lower connecting rod 89. The left connecting member 86 and the right connecting member 87 are respectively connected to the two ends of the roller chain 92. The upper connecting rod 88 and the lower connecting rod 89 are respectively located above and below the roller chain 92. The right ends are fixedly connected to the right connecting member 87, and the left ends pass through the connecting rod holes on the left connecting member 86 and slide with the left connecting member 86. The upper connecting rod 88 and the lower connecting rod 89 extending to the left side of the left connecting member 86 are respectively provided with compression springs 90. The left ends of the upper connecting rod 88 and the lower connecting rod 89 located on the left side of the compression spring 90 are respectively installed with nuts 91 through threads.

[0016] Alternatively, the left ends of the upper connecting rod 88 and the lower connecting rod 89 are connected to the left connecting member 86 via tension springs, which can also tighten the transmission chain 83 to ensure that the left door 1 and the right door 2 are opened and closed synchronously.

[0017] The left wheel 81 and the right wheel 82 of the synchronization device 8 are double groove wheels (such as Figure 4 、 Figure 5 The left end of the lower transmission chain belt 83 passes by the rear side, left side and front side of the lower groove of the left wheel 81, and the end is fixedly connected to the right wheel 82.

[0018] The two transmission chains 83 intersect with each other when viewed from above, and are staggered in upper and lower positions to ensure that the two transmission chains 83 do not interfere with each other, thereby driving the left door 1 and the right door 2 to open and close synchronously.

[0019] Each transmission chain 83 is composed of two sections, the right end of the left section transmission chain 83 and the left end of the right section transmission chain 83 are connected by a tension spring 93 (such as Figure 4 As shown), or by tensioning the compression spring 90 (as Figure 5 The purpose is also to tighten the transmission chain 83 to ensure that the left door 1 and the right door 2 open and close synchronously.

[0020] The transmission chain belt 83 is a double-sided toothed synchronous belt 84, a roller chain 92, a V-belt, a flat belt or a steel rope, and the left wheel 81 and the right wheel 82 are matched to form a double synchronous wheel, a double sprocket, a double-groove V-belt pulley, a double-groove flat belt pulley or a double-groove steel rope pulley.

[0021] Working principle: When the two doors are driven by a reduction motor 9, the reduction motor 9 will drive the door on that side to open and close through the drive shaft, electromagnetic clutch and door shaft on the side where the reduction motor 9 is installed. The synchronization device 8 installed between the left drive shaft 5 and the right drive shaft 7 will drive the drive shaft, electromagnetic clutch and door shaft on the other side to rotate through the left wheel 81, right wheel 82 and transmission chain belt 83, thereby driving the door on the other side to open and close, achieving the purpose of driving the two doors to open and close synchronously.

[0022] When the two doors are driven by a reduction motor 9 respectively, the reduction motor 9 on the left drives the left door 1 to open and close through the left transmission shaft 5, the left electromagnetic clutch 4 and the left door shaft 11, and the reduction motor 9 on the right drives the right door 2 to open and close through the right transmission shaft 7, the right electromagnetic clutch 6 and the right door shaft 21. The synchronizing device 8 installed between the left transmission shaft 5 and the right transmission shaft 7 will make the left transmission shaft 5 and the right transmission shaft 7 rotate synchronously through the left wheel 81, the right wheel 82 and the transmission chain belt 83, so as to achieve the purpose of controlling the synchronous opening and closing of the left door 1 and the right door 2.

[0023] When two doors are driven by a single reduction motor 9, the power to one electromagnetic clutch can be manually or programmatically disconnected. This prevents the drive shaft on that side from rotating the door shaft and door, thereby controlling the opening and closing of only one door. When two doors are each driven by a single reduction motor 9, if only one door needs to be opened or closed, the power to one electromagnetic clutch and reduction motor (on the same or different sides) can be manually or programmatically disconnected. This prevents the drive shaft on the same side of the electromagnetic clutch from rotating the door shaft and door, thereby controlling the opening and closing of only one door. Opening and closing a door individually saves energy, is suitable for low-traffic areas, and is also suitable for door maintenance, providing greater convenience and user-friendliness.

[0024] If the external force applied to the two doors during opening or closing is excessive, exceeding the upper limit of the electromagnetic clutch's torque transmission capacity, relative rotation will occur between the input and output components of the electromagnetic clutch, providing overload protection and buffering for both the synchronizing and transmission mechanisms. If the two doors become out of sync due to external force or other reasons, one door will fully close while the other does not. When a sensor detects this, it transmits information to the controller, which disconnects the power to the electromagnetic clutch on the same side of the fully closed door, allowing the remaining door on the other side to continue closing completely. This restores both doors to a fully closed, synchronized state. Reconnecting the electromagnetic clutch automatically restores synchronization when the doors are reopened. Compared to existing technologies, adjusting and correcting this out-of-sync situation is significantly easier.
