Most existing mechanisms struggle to achieve high-precision motion control of the door body. During opening, the door often experiences jamming and shaking, failing to meet the stringent requirements of opening accuracy and stability in special environments such as high-end laboratories and precision instrument rooms. Furthermore, the traditional design layout is not rational enough, leading to difficulties in maintenance and repair, severely impacting the equipment's efficiency and lifespan. Innovative transmission mechanism designs are urgently needed to improve the current situation.
[0003] Existing door opener transmission mechanisms suffer from low integration, with components operating independently and lacking efficient coordination. This results in a bulky overall structure, complex installation, and significant difficulties in troubleshooting and maintenance. Furthermore, their poor transmission accuracy leads to positional deviations during door lifting and instability during translation, failing to meet the demands of scenarios requiring high door opening precision, such as high-end automated warehouses and precision instrument manufacturing workshops. Therefore, we propose a new door opener transmission mechanism to address these issues. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.
[0024] Example 1, refer to Figure 1-5 In this embodiment, to address the problems of existing door opener transmission mechanisms having low integration, independent components, and a lack of efficient coordination, resulting in large overall size, complex installation, and extremely inconvenient troubleshooting and maintenance, as well as poor transmission accuracy, which makes the door prone to positional deviation during lifting and difficult to maintain a stable trajectory during translation, this utility model discloses a door opener transmission mechanism.
[0025] The system comprises a base housing 1 and an upper housing 2, both employing a modular design. The base housing 1 is internally divided into a power transmission chamber 3 and a limit adjustment chamber 4. The upper housing 2 is divided by a partition plate 5 into a shaft movement chamber 6 and a main control module installation area 7. The limit adjustment chamber 4 is located directly in front of the power transmission chamber 3 and contains a pair of vertically distributed, variable-height arc-shaped limit tracks 9. By incorporating a specific motor drive mechanism within this door opener, in conjunction with the drive gear 16 and driven gear 15 within the power transmission chamber 3, and utilizing the variable-height arc-shaped limit tracks 9 within the limit adjustment chamber 4, along with cooperating limit rollers 14 and a rotating shaft 8, the system achieves the goal of driving the door to rotate and lift around the rotating shaft 8 at a small angle. This design enables precise control of the door's movement, allowing for smooth position adjustment during the initial opening phase and reducing the impact at the moment of opening. Subsequently, with the help of the linkage of various components, the door can smoothly perform the translational opening operation along the rotation axis 8, realizing a high-precision, stable and smooth opening process, which greatly improves the performance of the automatic door in operation and effectively meets the demand for high-precision opening of the automatic door.
[0026] The variable-height arc-shaped limiting track 9 has a semi-circular arc structure, and the upper and lower variable-height arc-shaped limiting tracks 9 are on the same vertical line. The starting and ending ends of the variable-height arc-shaped limiting track 9 are provided with a low-plane area 10, and the middle part is provided with a high-plane area 11. The low-plane area 10 and the high-plane area 11 are connected by a transition ramp 12. By installing the variable-height arc-shaped limiting track 9 with a semi-circular arc structure and the upper and lower parts on the same vertical line, and with the low-plane area 10 at the starting and ending ends and the high-plane area 11 in the middle connected by the transition ramp 12, the purpose of accurately guiding the door's movement trajectory is achieved. This makes the door's movement smoother, more precise, and controllable during small-angle rotation and lifting around the rotation axis 8, as well as during translational opening along the axis, effectively avoiding door movement deviation and improving the stability and reliability of the entire door opening machine transmission mechanism.
[0027] A through-hole 13 is provided in the limiting adjustment cavity 4, penetrating the entire base housing 1. A rotating shaft 8 is axially mounted within the through-hole 13. The axis of the rotating shaft 8 is aligned with the center of the variable-height arc-shaped limiting track 9 on the same vertical line. By creating a through-hole 13 in the limiting adjustment cavity 4 that penetrates the entire base housing 1, and axially mounting the rotating shaft 8 within the through-hole 13, while ensuring that the axis of the rotating shaft 8 is aligned with the center of the variable-height arc-shaped limiting track 9 on the same vertical line, the purpose of constructing a precise transmission and limiting system is achieved. This allows the rotating shaft 8 to move stably axially within the through-hole 13, providing stable support for the small-angle rotation and lifting of the door around the axis, as well as subsequent axial translation for door opening. This ensures that the door movement strictly follows the preset trajectory, effectively guaranteeing the accuracy and stability of the door opener's transmission mechanism, and significantly improving the overall transmission efficiency and reliability.
[0028] A limiting roller 14 is axially connected and installed on the rotating shaft 8. The rotation axis 8 of the limiting roller 14 is perpendicular to the axis of the rotating shaft 8. The limiting roller 14 can roll on the variable-height arc-shaped limiting track 9. Both the upper and lower limiting rollers 14 are set in this manner. By axially connecting and installing the limiting roller 14 on the rotating shaft 8, ensuring that the rotation axis 8 of the limiting roller 14 is perpendicular to the axis of the rotating shaft 8, and allowing the limiting roller 14 to roll on the variable-height arc-shaped limiting track 9, the purpose of precisely limiting and guiding the movement path of the door is achieved. This allows for precise constraint of the door's movement during small-angle rotation and lifting around the rotating shaft 8, as well as during axial translation and opening. The rolling of the limiting roller 14 on the variable-height arc-shaped limiting track 9 effectively constrains the door's movement, preventing deviation and swaying during movement. This significantly improves the stability and accuracy of the door's movement, thereby optimizing the overall operation of the door opening mechanism.
[0029] Two driven gears 15 are welded and fixed on the rotating shaft 8. The height of the driven gears 15 is the same as the diameter of the limiting roller 14. The lowest position of the driven gears 15 is level with the lowest position of the limiting roller 14, and the highest position is level with the highest position of the limiting roller 14. At the intersection of the driven gears 15 and the limiting roller 14 at the same height, there is no setting between the two driven gears 15. By welding and fixing two driven gears 15 on the rotating shaft 8 and ensuring that the height of the driven gears 15 is the same as the diameter of the limiting roller 14, it is ensured that the lowest and highest positions of the driven gears 15 are level with the corresponding positions of the limiting roller 14. At the intersection of the driven gears 15 and the limiting roller 14 at the same height, there is no setting between the two driven gears 15, thus achieving the purpose of optimizing the coordination between power transmission and door movement. Driven by the driving gear 16, the driven gear 15 can accurately transmit power to the rotating shaft 8. At the same time, due to the special layout of the driven gear 15 and the limiting roller 14, the two cooperate with each other during the small-angle rotation and lifting of the door body around the rotating shaft 8 and the door opening process along the shaft, making the door body movement more stable and smooth. This effectively avoids jamming and deviation caused by mismatch between power transmission and door body limiting, and further improves the stability and efficiency of the door opening machine transmission mechanism.
[0030] A drive gear 16 is axially movably connected and installed within the power transmission chamber 3. Both the drive gear 16 and the driven gear 15 are spur gears. The diameter of the drive gear 16 is 3.5 times larger than that of the driven gear 15. By axially movably connecting and installing the drive gear 16 within the power transmission chamber 3, and by using spur gears for both the drive gear 16 and the driven gear 15, with the diameter of the drive gear 16 being 3.5 times larger than that of the driven gear 15, the goal of achieving efficient power transmission and precise torque adjustment is achieved. When the motor drives the drive gear 16, due to its larger diameter, its rotational speed per unit time is relatively low. According to the gear transmission principle, this allows for the output of a larger torque, thereby driving the driven gear 15 to operate stably. This design provides sufficient and stable power to the door body during the small-angle rotation and lifting of the door body around the rotating axis 8 and the translational movement along the axis to open the door. This ensures that the door body moves smoothly and steadily, effectively overcomes the resistance caused by factors such as the weight of the door body, and improves the operational reliability and power transmission efficiency of the entire door opening machine transmission mechanism under different working conditions.
[0031] A slot 17 is provided directly behind the limit adjustment cavity 4. The slot 17 is used for power transmission between the driving gear 16 and the driven gear 15. By providing a slot 17 directly behind the limit adjustment cavity 4 for power transmission between the driving gear 16 and the driven gear 15, the goal of constructing an efficient power transmission path and optimizing the transmission layout is achieved. This allows the power of the driving gear 16 to be conveniently and directly transmitted to the driven gear 15, avoiding unnecessary losses and interference in the power transmission process. This ensures timely and stable power transmission when the door body rotates and lifts at a small angle around the rotation axis 8 and moves along the axis to open the door. This design greatly improves the efficiency and reliability of the power transmission of the door opener's transmission mechanism, making the door body movement response more sensitive and further ensuring the high precision and smoothness of the entire door opening process.
[0032] The upper cover housing 2 is securely mounted directly above the base housing 1. The area of the partition plate 5 inside the upper cover housing 2 is half the plane area of the upper cover housing 2. The cavity directly below the partition plate 5 is the shaft system motion chamber 6, which provides space for the vertical movement of the rotating shaft 8. The main control module 18 is securely mounted directly above the partition plate 5. The drive motor 19 is securely mounted inside the upper cover housing 2. The drive motor 19 is connected to the drive gear 16. By securely mounting the upper cover housing 2 directly above the base housing 1 and setting the partition plate 5 with an area half its plane area inside the upper cover housing 2, forming the shaft system motion chamber 6 directly below the partition plate 5, sufficient space is provided for the vertical movement of the rotating shaft 8. The main control module 18 is securely mounted directly above the partition plate 5. At the same time, the drive motor 19 is securely mounted inside the upper cover housing 2 and connected to the drive gear 16, the purpose of optimizing the mechanism layout and ensuring the coordinated operation of each component is achieved. This design enables the rotating shaft 8 to move freely and stably in the vertical direction within the shaft system motion chamber 6, providing stable support for the small-angle rotation and lifting of the door body around the shaft, as well as its translational opening along the shaft. The main control module 18 can precisely control the operation of the drive motor 19, which in turn can transmit power to the driving gear 16 in a timely and efficient manner, thereby driving the driven gear 15 and achieving precise control of the door body's movement. This design significantly improves the overall stability, coordination, and controllability of the door opener's transmission mechanism, greatly optimizes the automated door opening process, and effectively ensures the high precision and smoothness of the door body's movement.
[0033] The specific working principle is as follows: Through an innovative modular architecture design, the base housing 1 and the upper cover housing 2 are uniquely combined. Internally, a power transmission chamber 3, a limit adjustment chamber 4, a shaft movement chamber 6, and a main control module installation area 7 are precisely divided. Furthermore, a series of collaborative components, including a drive gear 16, a driven gear 15, a variable-height arc-shaped limit track 9, limit rollers 14, and a rotating shaft 8, are innovatively configured, achieving the goal of creating a unique door opener transmission mechanism on the market. This enables the door to rotate and lift around the rotating shaft 8 at a small angle with unique high precision, and then translate along the shaft to open. This unique operating mode greatly improves the efficiency and quality of automated door opening, effectively meeting various special application scenarios with extremely high requirements for opening precision and stability, filling a gap in the market in this field. Thanks to the aforementioned unique modular architecture design, the installation positions of each component are clear and independent, achieving convenient installation, inspection, and maintenance. In practical use, when the motor or other components malfunction, maintenance personnel can directly operate on the corresponding area based on the modular features not found in other products on the market, without the need for complex and time-consuming overall disassembly. This advantage significantly shortens repair time, reduces maintenance costs, improves equipment availability and lifespan, and brings users an unprecedented level of convenience, making it stand out among similar products on the market.
[0034] Advantages of the innovative gate opener transmission mechanism: In the actual operation of this gate opener transmission mechanism, when the device starts working, the motor outputs power to drive the drive gear 16. Since the diameter of the drive gear 16 is 3.5 times larger than that of the driven gear 15, during power transmission, the drive gear 16 drives the driven gear 15 to rotate due to its larger torque. Simultaneously, the variable-height arc-shaped limit track 9 within the limit adjustment cavity 4 cooperates with the limit roller 14, allowing the rotating shaft 8, which houses the limit roller 14 and the driven gear 15, to not only rotate around its own axis when driven by the drive gear 16, but also to achieve vertical upward movement along the contour of the variable-height arc-shaped limit track 9. The high structural design of the driving gear 16 provides ample space for the rotation of the two driven gears 15 during the upward process, which can fully meet the needs of the two auxiliary gears to rotate and rise at the same time, ensuring that the entire transmission process is smooth and unobstructed. This enables the door to rotate and lift around the rotating axis 8 with high precision, and then move along the axis to open the door stably. This key design point plays a vital role in ensuring the efficient and stable operation of the door opening machine transmission mechanism involved in this utility model patent, and therefore it is described in detail in the specification of this utility model patent.
[0035] A high-precision door opener transmission mechanism solution suitable for confined spaces: This utility model discloses a door opener transmission mechanism, which is particularly suitable for scenarios where space is limited and conventional sliding door opening requirements cannot be met. Through a unique modular architecture, it integrates power transmission, limit adjustment, and other functional chambers within a limited space. With the coordinated operation of components such as the driving gear 16, driven gear 15, and variable-height arc-shaped limit track 9, it can precisely control the door to first rotate and lift around the rotation axis 8 at a small angle, cleverly utilizing vertical space, and then slide along the axis to open the door. The entire process is extremely precise, meeting the needs of places such as narrow passages and precision instrument rooms where there is a lack of sliding space and stringent requirements for door opening precision.
[0036] The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.
[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
