[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] A vertical crank arm swing door machine, such as Figure 1 、 4 , 5, comprising a motor 1, a planetary gearbox 2 and a thickened bearing chamber 3; one side of the planetary gearbox 2 is directly connected to the motor 1, and the thickened bearing chamber 3 is provided on the other side of the planetary gearbox 2; two support bearings 3-1 are provided in the thickened bearing chamber 3 to assist in supporting the output shaft 4, and the two support bearings 3-1 are respectively adhered to the inner side surfaces at both ends of the thickened bearing chamber 3; the thickened bearing chamber 3 is provided with a raised bottom plate mounting surface 3-2.

[0023] Specifically, by thickening the bearing chamber 3, not only the overall strength of the bearing chamber 3 is improved, but also its support capacity for the output shaft 4 is enhanced, which can effectively reduce bearing wear and loosening caused by vibration or long-term operation, thereby extending the service life of the equipment. At the same time, the output shaft is supported by two bearings. Compared with the single-bearing design, it can more effectively disperse the load, reduce uneven force on the bearing, and improve the stability and reliability of the system. The design of the planetary gearbox 2 directly connected to the motor 1 reduces energy loss during power transmission and improves the overall transmission efficiency. The two supporting bearings fit tightly into the inner surface of the thickened bearing chamber to ensure the stability and accuracy of the output shaft during rotation, which is particularly important for application scenarios that require precise control of the door opening and closing position. The raised base plate mounting surface 3-2 enables the door opener to be more firmly fixed to the foundation during installation. At the same time, additional mounting holes or positioning structures are provided to simplify the installation process and improve installation accuracy. The overall solution is applicable to door bodies of various specifications and weights. By adjusting the motor power and the transmission ratio of the planetary gearbox, it can flexibly respond to different usage requirements.

[0024] As a preferred embodiment of the above, Figure 4 As shown, the motor 1 is directly connected to the first-stage gear of the planetary gearbox 2 through an output gear.

[0025] Specifically, the structure in which the motor 1 is directly connected to the first-stage gear of the planetary gearbox 2 through the output gear reduces intermediate transmission components, the overall structure of the system is more compact, and the risk of failure due to loose or worn components is reduced. At the same time, the direct-connected transmission method also reduces the transmission of vibration and noise, improves the stability and smooth operation of the door opener, and the direct-connected transmission method enables the power output by the motor 1 to be transmitted to the planetary gearbox 2 more quickly, thereby driving the movement of the door body, thereby having a fast response capability to adapt to occasions that require precise control of the time and position of opening and closing the door.

[0026] As a preferred embodiment of the above, Figure 4 As shown, the planetary gearbox 2 is provided with four gear stages.

[0027] As a preferred embodiment of the above, Figure 1 、 2 As shown, a curved shell 5 is also provided, and a door opener mounting surface 5-1 is provided on the back of the curved shell 5.

[0028] Specifically, the streamlined curved shell design makes the door opener more visually beautiful, which is in line with the modern decoration style of the commercial environment and enhances the customer's shopping experience. The back door opener mounting surface 5-1 is designed with multiple mounting holes and positioning structures, which is convenient for rapid installation in areas with dense crowds and limited space. At the same time, the sturdy curved shell can effectively resist external impacts and malicious damage, protect internal mechanical components from damage, improve the safety of the door opener, and prevent damage to others.

[0029] As a preferred embodiment of the above, Figure 1 As shown, a door opening arm 6 is also provided, which is arranged on the top of the arc surface housing 5 and connected to the output shaft 4.

[0030] Specifically, by further providing a door-opening arm 6, which is positioned at the top of the curved housing 5 and connected to the output shaft 4, the door-opening arm 6 is directly connected to the output shaft 4, eliminating intermediate transmission links and improving transmission efficiency. This means that the power output by the motor can be more directly and efficiently converted into the movement of the door-opening arm, thereby driving the opening and closing of the door. The close connection between the door-opening arm 6 and the output shaft 4 makes the door opening action more precise and controllable. By adjusting the rotation angle and speed of the output shaft 4, the movement trajectory and force of the door-opening arm 6 can be precisely controlled, thereby achieving smooth opening and closing of the door.

[0031] As a preferred embodiment of the above, Figure 1 As shown, the door opening arm 6 is further provided with an arc-shaped bend 6 - 1 .

[0032] Specifically, the design of the arcuate bend 6-1 enables the door opening arm 6 to more smoothly follow the movement trajectory of the door body when pushing the door body. This design reduces resistance and friction during the door opening process, making the opening and closing of the door body smoother and more fluid. The arcuate bend 6-1 also helps to reduce energy loss during the transmission process. Because the bent portion can better guide the movement direction of the door opening arm 6, the transmission is more direct and efficient, thereby reducing the inefficiency caused by poor transmission or energy dissipation, and helps to reduce the safety risks caused by the door body suddenly closing or clamping objects or people during the door opening process. When the door body encounters an obstacle during the opening or closing process, the arcuate bend of the door opening arm 6 can play a certain buffering role, reducing the risk of pinching.

[0033] As a preferred embodiment of the above, Figure 1 As shown, a double ring member 6-2 for fixing the door is provided at the end of the door opening arm 6.

[0034] Specifically, the double ring 6-2 design provides a more stable and secure connection point for tightly connecting the door opening arm 6 to the door body. This design ensures the stability and reliability of the door body during opening and closing, and reduces the risk of failure caused by loose or falling connections.

[0035] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
