[0021] 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 of the embodiments.

[0022] In the description of the present invention, it should be noted that the directions or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the directions 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0023] A compact door opener, such as Figure 1 , 3 As shown, it includes a door opener body 1 and a pull rod 2; a power group 3 is arranged in the door opener body 1; the power group 3 includes a motor 4, a first gear 5, an output gear 6 and a second gear 7, and the motor 4 drives the first gear 5; the output gear 6 is fixed on the output shaft 7, and the upper and lower gears of the output gear 6 are driven by the second gear 7 and the first gear 5 respectively; a transition gear 6-1 is arranged between the upper and lower gears of the output gear 6, and the transition gear 6-1 drives the matching transition gear 7-1 of the second gear 7.

[0024] Specifically, the invention comprises a door opener body 1 and a pull rod 2; a power group 3 is arranged in the door opener body 1; the power group 3 comprises a motor 4, a first gear 5, an output gear 6 and a second gear 7, the motor 4 drives the first gear 5; the output gear 6 is fixed on the output shaft, and the upper and lower gears of the output gear 6 are driven by the second gear 7 and the first gear 5 respectively; a transition gear 6-1 is arranged between the upper and lower gears of the output gear 6, and the transition gear 6-1 drives the second gear 7 to move with the matching transition gear 7-1, so that the motor 4 of the power group 3 in the door opener body 1 drives the first gear 5, and then the first gear 5 drives the lower gear of the output gear 6, and at the same time drives the transition gear 6-1 to drive the matching transition gear 7-1, and then drives the second gear 7 to drive the upper gear of the output gear 6, and further drives the pull rod 2 to move. By adding the transition gear 6-1, the door opener can better control and adjust the power transmission method, so that the power transmission between the upper and lower gears of the output gear 6 is smoother, and the power loss is reduced, thereby improving the efficiency of the door opener. And because the upper and lower gears of the output gear 6 are driven by the second gear 7 and the first gear 5 respectively, the presence of the transition gear 6-1 can ensure a more balanced load distribution between the two gears. This reduces the wear of the gears, improves the stability and service life of the entire door opener, and at the same time, the mechanical structure of the door opener and the proportional relationship between the gears can be more easily adjusted through the transition gear 6-1 to adapt to different application scenarios and door opening requirements, further making the door opener more versatile and adaptable. At the same time, the direct impact and friction between the gears in the power group 3 are reduced, further reducing noise and vibration, and the entire door opener mechanism is more compact, which can further reduce the space it occupies and its own weight.

[0025] As a preferred embodiment of the above, Figure 3 As shown, the motor 4 drives the first gear 5 to mesh in a helical gear meshing manner, and the first gear 5 drives the lower gear of the output gear 6 to mesh in a spur gear meshing manner.

[0026] Specifically, the meshing mode of the first gear 5 driven by the motor 4 is helical gear meshing, and the meshing mode of the gear below the output gear 6 driven by the first gear 5 is a spur gear meshing structure, thereby further improving the efficiency and stability of its basic transmission.

[0027] As a preferred embodiment of the above, Figure 3 As shown, the meshing mode of the second gear 7 driving the upper gear of the output gear 6 is spur gear meshing.

[0028] Specifically, the meshing mode of the upper gear of the output gear 6 driven by the second gear 7 is a spur gear meshing structure, and further through the combination of helical gears and spur gears, the spatial layout is optimized while ensuring the transmission performance.

[0029] As a preferred embodiment of the above, Figure 3 As shown, the diameter of the transition gear 6 - 1 is smaller than the upper and lower gears of the output gear 6 .

[0030] As a preferred embodiment of the above, Figure 3 As shown, the size of the mating transition gear 7 - 1 is adapted to the diameter of the upper and lower gears of the transition gear 6 - 1 which is smaller than that of the output gear 6 .

[0031] Specifically, by adopting a structure in which the diameter of the transition gear 6-1 is smaller than the upper and lower gears of the output gear 6 and the size of the matching transition gear 7-1 is adapted to the transition gear 6-1 being smaller than the diameter of the upper and lower gears of the output gear 6, the power transmission capacity is further optimized on the basis of reducing the overall size.

[0032] As a preferred embodiment of the above, Figure 3 As shown, a control group 8 is arranged in the door opener body 1, and the power group 3 and the control group 8 are arranged on both sides of the door opener body 1.

[0033] Specifically, a control group 8 is provided in the door opener body 1, and the power group 3 and the control group 8 are arranged on both sides of the door opener body 1, thereby making the structure of the entire door opener more compact, and further reducing the space occupied and its own weight.

[0034] As a preferred embodiment of the above, Figure 1 As shown, the door opener body 1 and the pull rod 2 are connected via a compact connecting arm 9 .

[0035] Specifically, the structure in which the door opener body 1 and the pull rod 2 are connected by the compact connecting arm 9 further reduces the space occupied by the entire door opener and its own weight.

[0036] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
