Abstract
Description
Technical Field
[0001] This utility model relates to the field of sliding door operators, and in particular to a sliding door operator that can quickly switch transmission modes. Background Technology
[0002] There are two types of sliding door operators sold in domestic and international markets: rack and pinion sliding door operators and sprocket and chain sliding door operators. Different application scenarios have different requirements for the transmission method. For example, synchronous belt drive is suitable for occasions that require high precision and low noise (such as high-end office buildings and hotels), while chain drive is suitable for industrial environments with high load and high torque (such as factories and warehouses). When the same door operator needs to be used in different scenarios, the entire transmission system must be replaced. The two transmission methods are incompatible, which not only increases the equipment cost, but also prolongs the installation and commissioning time.
[0003] Therefore, there is an urgent need for a sliding door operator that can quickly switch between drive modes, allowing users to switch between synchronous belt drive and chain drive simply by replacing the drive components (such as synchronous belts or chains), without replacing the entire equipment. This improves the equipment's versatility, reduces maintenance costs, shortens installation and commissioning time, and meets the needs of different application scenarios. Utility Model Content
[0004] The purpose of this utility model is to provide a sliding door operator that can quickly switch transmission modes, enabling rapid replacement of chains and timing belts. By simply replacing a single part (chain or timing belt), it is possible to switch freely between chain and timing belt modes, thereby solving the problems mentioned in the background art.
[0005] The technical problem solved by this utility model is achieved through the following technical solution:
[0006] A sliding door operator with a fast-switching transmission mode includes a door operator bracket and a sliding door operator body. The sliding door operator body includes a base, which is fixedly mounted on the door operator bracket. A motor is fixedly mounted on the upper surface of the base. A combination wheel assembly is provided on the upright plate of the base. A driven wheel is rotatably mounted on one end face of the combination wheel assembly on the door operator bracket. A transmission component connects the driven wheel and the combination wheel assembly. The combination wheel assembly is provided with a toothed structure including a first transmission tooth and a second transmission tooth for switching between different types of transmission components. The output end of the motor is connected to the combination wheel assembly through a clutch-type transmission assembly.
[0007] Preferably, the clutch-type transmission assembly includes a worm gear shaft, on which a worm gear is rotatably mounted. The combined wheel component is fixedly connected to the worm gear shaft. The worm gear shaft has a hollow section, and a clutch pinion is slidably mounted in the worm gear shaft, passing through the hollow section. A flat key is fixedly mounted on the clutch pinion, and a compression spring is connected between the flat key and the inner groove of the hollow section. The worm gear has a worm gear groove, and the flat key can be embedded in the worm gear groove.
[0008] Preferably, the clutch-type transmission assembly further includes a clutch handle, and the inner end of the clutch handle is provided with a cam portion, which abuts against the clutch pinion.
[0009] Preferably, the gantry crane bracket includes a bracket horizontal plate and a bracket side plate, with the bracket side plate fixedly installed on the left and right sides of the bracket horizontal plate.
[0010] Preferably, a circuit board is installed on the base, and the circuit board is electrically connected to the motor. A limit switch is installed on the circuit board. When the limit switch receives a sensing signal, it sends a signal to the circuit board to de-energize the motor, thereby realizing the action of opening and closing the door.
[0011] Preferably, the first transmission tooth is configured as a sprocket tooth for chain drive, and the second transmission tooth is configured as a synchronous belt pulley tooth for synchronous belt drive.
[0012] The advantages and positive effects of this utility model are:
[0013] This utility model achieves rapid switching of transmission modes through an innovative design that integrates sprocket teeth and synchronous belt teeth into a combined wheel assembly. Only the chain or synchronous belt needs to be replaced to adapt to different scenarios. Combined with a clutch-type manual operating mechanism, it ensures safe emergency operation during power outages or debugging. Simultaneously, the modular structure and standardized components simplify installation and maintenance processes and improve versatility. With magnetic limiters and intelligent control, it achieves precise positioning and efficient power transmission for door opening and closing, combining high reliability, environmental adaptability, and cost-effectiveness, making it suitable for sliding door system needs in various scenarios.

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. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in an illustrative manner. Therefore, they only show the components related to the present invention.
[0026] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.
[0027] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:
[0028] Please see Figures 1-9 This utility model provides an embodiment comprising a sliding door operator with a fast-switching transmission mode and a sliding door 1. The bottom of the sliding door 1 is equipped with rollers 4 for movement. Fixed components 2 are respectively installed at both ends of the sliding door 1, and a transmission component 7 is connected between the two fixed components 2. A magnetic steel fixing frame 5 is fixedly installed on the sliding door 1, and a magnet 6 is fixedly installed on the magnetic steel fixing frame 5. The fast-switching sliding door operator includes a door operator bracket 9 and a sliding door operator body 11. The sliding door operator body 11 includes a base 12, which is fixedly installed on the door operator bracket 9. A motor 14 is fixedly installed on the upper surface of the base 12. Combined wheels 16 are provided on the upright plate of the base 12. The door operator bracket 9... A driven wheel 15 is rotatably mounted on one end face of the combined wheel assembly 16. A transmission component 7 is connected between the driven wheel 15 and the combined wheel assembly 16. The transmission component 7 can be a synchronous belt or a transmission chain. The combined wheel assembly 16 is provided with a toothed structure including a first transmission tooth and a second transmission tooth. The first transmission tooth is set as a sprocket tooth for chain transmission, and the second transmission tooth is set as a synchronous belt pulley tooth for synchronous belt transmission. This structure is used for switching between different types of transmission components 7. The output end of the motor 14 is connected to the combined wheel assembly 16 through a clutch-type transmission assembly. A circuit board 13 is mounted on the base 12. The circuit board 13 is electrically connected to the motor 14. A limit switch 18 is mounted on the circuit board 13.
[0029] The door operator bracket 9 is composed of two horizontal bracket plates 17 and two side bracket plates 20, which are fixed to the ground with expansion bolts. The sliding door operator body 11 is fixed to the door operator bracket 9 with bolts. The transmission component 7 is installed between the driven wheel 15 and the combined wheel component 16. The transmission component 7 is fixed to the fixing component 2 through the connecting component 3. The magnet fixing frame 5 is fixed to the part of the sliding door 1 near the edge (the distance is determined by the user) with bolts, and the magnet 6 is aligned with the height of the limit switch 18. Because the combined wheel component 16 contains both a synchronous belt pulley and a sprocket, and the fixing component 2 and the connecting component 3 are connected by a chain knot, the connection by chain and the connection by synchronous belt are interchangeable. This allows for quick switching between a synchronous belt sliding door operator and a chain sliding door operator simply by changing the chain or the synchronous belt.
[0030] The operating principle is as follows:
[0031] The sliding door operator is connected to mains power, which is input to circuit board 13. Circuit board 13 supplies power to motor 14. The motor shaft rotates, causing the combined wheel assembly 16 to rotate. The combined wheel assembly 16 drives the transmission component 7 to move. When the transmission component 7 moves, it drives the connecting assembly 3, the fixing assembly 2, the sliding door 1, and the magnet 6 to move together. When the magnet 6 reaches the sensing area of the limit switch 18, the limit switch 18 sends a signal to circuit board 13, causing motor 14 to be de-energized and the moving door to stop, thus realizing the opening / closing action.
[0032] It is worth mentioning that, in this embodiment, the clutch-type transmission assembly includes a worm gear assembly and a worm. The worm is fixedly connected to the output end of the motor 14 to achieve transmission. The worm gear assembly includes a worm gear shaft 26 and a worm gear 23. The worm gear 23 is rotatably mounted on the worm gear shaft 26. The combined wheel component 16 is fixedly connected to the worm gear shaft 26. The worm gear shaft 26 has a hollow section. A clutch pin 22 is slidably mounted in the worm gear shaft 26, passing through the hollow section. A flat key 24 is fixedly mounted on the clutch pin 22. A compression spring 25 connects the flat key 24 and the inner groove of the hollow section. The worm gear 23 has a worm gear groove, and the flat key 24 can be embedded in the worm gear groove.
[0033] Under normal circumstances, the clutch does not need to be disengaged, as the sliding door operator is electrically operated to open and close. However, during installation, commissioning, or power outages, the clutch needs to be disengaged to manually open and close the door.
[0034] Figure 8 The display shows the clutch is not engaged. The motor 14 is powered on and drives the worm gear, which in turn drives the worm wheel 23. At the same time, the force is transmitted to the worm wheel shaft 26, the combined wheel assembly 16, and the transmission component 7 through the key 24, thereby driving the opening and closing of the sliding door 1.
[0035] Figure 9 The display shows the clutch is open. Pulling the clutch handle 21 outward by 90 degrees with the clutch key will use the cam principle to push the clutch shaft 22 to push the flat key 24 out of the worm gear groove, causing the worm gear 23 and the worm gear shaft 26 to disengage. At this time, you can manually push and pull the door. Push the clutch handle 21 back to its original position, and the clutch shaft 22 will be pushed back into the worm gear groove by the compression spring 25.
[0036] In summary, this utility model achieves rapid switching of transmission modes through an innovative design that integrates sprocket teeth and synchronous belt teeth into a combined wheel assembly. Only the chain or synchronous belt needs to be replaced to adapt to different scenarios. Combined with a clutch-type manual operating mechanism, it ensures safe emergency operation during power outages or debugging. Furthermore, the modular structure and standardized components simplify installation and maintenance processes and enhance versatility. With the addition of magnetic limit switches and intelligent control, it achieves precise positioning and efficient power transmission for door opening and closing, combining high reliability, environmental adaptability, and cost-effectiveness, making it suitable for sliding door system needs in various scenarios.
[0037] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
