Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0055] The following is combined Figures 1-12 This invention describes a direct-drive, low-noise rhythmic motor core.

[0056] Understandably, referring to Figure 1 , Figure 2 , Figure 5 and Figure 6 The direct-drive low-noise rhythm motor core includes a rhythm frame 1, a direct-drive power motor 2, a crankshaft swing actuator 3, and a coupling 4.

The direct-drive power motor 2 has a rotating shaft, and the other end of the crankshaft 32 is connected to the rotating shaft through the coupling 4.

[0057] The direct-drive low-noise rhythm motor core provided by this utility model directly drives the crankshaft swing actuator 3 through the direct-drive force motor 2, which reduces the number of transmission components, lowers noise, lowers the failure rate, and is convenient to install and disassemble, thus helping to reduce production and manufacturing costs.

[0058] Understandably, referring to Figure 1 , Figure 2 , Figure 5 , Figure 6 as well as Figures 8 to 11 In this embodiment of the utility model, the rhythm frame 1 includes a fixed support 11 and a vibration support 12, and the vibration support 12 is connected to the swing connector 5.

[0059] Specifically, in this embodiment of the invention, the fixed support 11 and the vibration support 12 have at least the following five transmission methods:

[0060] In implementation method 1, refer to Figure 6 The rhythm frame 1 also includes a connecting spring 13, which is disposed between the fixed support 11 and the vibration support 12, and the two ends of the connecting spring 13 are fixedly connected to the fixed support 11 and the vibration support 12 respectively; wherein, the fixed support 11 suspends the vibration support 12 through the connecting spring 13, so that the vibration support 12 can vibrate in the front and back directions, which is simple in structure and easy to assemble and manufacture.

[0061] In implementation method 2, refer to Figure 9 The fixed bracket 11 supports the vibration bracket 12 through the connecting spring 13, so that the vibration bracket 12 can vibrate in the front and back directions. The connecting spring 13 plays a supporting role, and the structure is simple and easy to assemble and manufacture.

[0062] In implementation method 3, refer to Figure 8 The rhythm frame 1 also includes a connecting spring 14, which is disposed between the fixed support 11 and the vibration support 12, and the two ends of the connecting spring 14 are respectively fixedly connected to the fixed support 11 and the vibration support 12.

[0063] The fixed support 11 suspends the vibration support 12 through the connecting spring 14, so that the vibration support 12 can vibrate in the front and back directions. The structure is simple and easy to assemble and manufacture. The connecting spring 14 can absorb and buffer the impact force generated during vibration, reduce damage to the equipment, and extend its service life.

[0064] In implementation method 4, refer to Figure 8 The fixed bracket 11 supports the vibration bracket 12 through the connecting spring 14, so that the vibration bracket 12 can vibrate in the front and back directions. The connecting spring 14 plays a supporting role, and the structure is simple and easy to assemble and manufacture.

[0065] In implementation method 5, refer to Figure 10 and Figure 11 The rhythm frame 1 also includes a hinged boom 16, which is disposed between the fixed support 11 and the vibrating support 12, with both ends of the hinged boom 16 hinged to the fixed support 11 and the vibrating support 12, respectively. The fixed support 11 suspends the vibrating support 12 via the hinged boom 16, allowing the vibrating support 12 to vibrate in the back-and-forth direction. The hinged connection between the hinged boom 16 and the fixed support 11 and the vibrating support 12 prevents the boom 161 from deforming and fatigued, thus preventing breakage.

[0066] Specifically, refer to Figure 10 and Figure 11 In this embodiment of the utility model, the articulated boom 16 includes a boom 161, two hinge seats 162 and two hinge shafts 163. One hinge seat 162 is connected to the fixed support 11, and the other hinge seat 162 is connected to the vibration support 12. The two hinge shafts 163 are connected to the two hinge seats 162 in a one-to-one correspondence. The two ends of the boom 161 are hinged to the two hinge seats 162 in a one-to-one correspondence through the corresponding hinge shafts 163. A first bearing is provided between the hinge seats 162 and the hinge shafts 163.

[0067] Because of the use of a hinge structure, the boom 161 can rotate around the hinge shaft 163, providing the boom 161 with a large range of motion and flexibility. This allows the boom 161 to adapt to different working angles and positions, increasing operational flexibility and ensuring smooth movement and equipment stability, which is very important for mechanical equipment that requires precise operation and vibration control.

[0068] Specifically, refer to Figure 6 and Figure 7 In this embodiment of the utility model, the direct drive motor 2 includes a drive motor 21 and a gearbox body 22. The gearbox body 22 is fixedly connected to the drive motor 21. The drive motor 21 has a rotating shaft, and the gearbox body 22 has a power input shaft. One end of the rotating shaft is connected to the power input shaft, and the other end of the power input shaft is connected to the crankshaft 32 of the crankshaft swing actuator 3 through a coupling 4.

[0069] The drive motor 21 and the gearbox body 22 are integrated as a whole, making installation and disassembly easier. The transmission components in the gearbox body 22 are located inside the housing, making lubrication easier and extending their service life.

[0070] It should be noted that, referring to Figure 1 In this embodiment, the crankshaft 32 has an eccentric structure, comprising a first section connected to the rocker connector 5 and a second section connected to the rotating shaft via a coupling 4, wherein the axes of the first and second sections are eccentrically arranged. Alternatively, refer to... Figure 2 The rotating shaft and the power input shaft are eccentrically set.

[0071] Specifically, refer to Figures 3 to 5In this embodiment of the present invention, the crankshaft oscillation actuator 3 further includes a bearing housing 31, which includes a bearing base 311, a bearing cover 312, a limiting ring 313, and a bearing body 314. The bearing base 311 and the bearing cover 312 are arranged vertically and are fixedly connected by a first bolt, forming a shaft hole between the bearing base 311 and the bearing cover 312. The bearing body 314 is provided between the bearing base 311 and the bearing cover 312, and both ends of the crankshaft 32 pass through the bearing body 314 and the shaft hole, respectively. The bearing base 311 and the bearing cover 312 are provided with a limiting ring 313 on their sides, which is used to restrict the bearing body 314 from sliding along the shaft hole.

[0072] The design of the bearing housing 31 provides precise guidance for the crankshaft 32, which helps to ensure the stability of the crankshaft 32's motion trajectory during rotation, reduce offset, and improve operational accuracy. The two ends of the crankshaft 32 pass through the bearing body 314 and the shaft hole. This design ensures a tight fit between the crankshaft 32 and the bearing, reduces clearance, and thus reduces vibration and noise during operation. This allows the crankshaft 32 to rotate smoothly, reduces energy loss, and improves transmission efficiency.

[0073] Specifically, refer to Figures 3 to 5 In this embodiment of the invention, the rocking connector 5 includes a bushing seat 51, a connecting plate 52, and a rocking spring 53. The bushing seat 51 is disposed on the fixed bracket 11 and sleeved on the crankshaft 32. A second bearing is disposed between the bushing seat 51 and the crankshaft 32.

One end of the rocking spring 53 is fixedly connected to the vibration bracket 12 by a second bolt, and the other end is fixedly connected to the connecting plate 52 by a third bolt. With the above structure, the rocking spring 53 can cause elastic deformation during the vibration of the rhythm frame 1 driven by the rocking connector 5.

[0074] Understandably, referring to Figure 12 In this embodiment of the utility model, a positioning structure is provided on the fixed bracket 11, which is used to limit the extreme position of the up and down swing of the swing connector 5.

[0075] With the above configuration, the positioning structure ensures that the swing connector 5 swings within a predetermined range, preventing it from exceeding the safe range due to external forces or mechanical failures, thereby avoiding potential damage or danger and helping to improve stability.

[0076] Specifically, refer to Figure 12 In this embodiment of the utility model, the positioning structure includes two positioning plates 6, which are spaced apart.

[0077] Each positioning plate 6 is provided with a positioning through groove 61. The positioning through grooves 61 of the two positioning plates 6 are arranged facing each other. The left and right sides of the swing connector 5 correspond one-to-one with the positioning through grooves 61 of the two positioning plates 6, and the left and right sides of the swing connector 5 extend into the corresponding positioning through grooves 61.

[0078] The upper and lower sides of the swing connector 5 are spaced from the upper and lower side walls of the positioning groove 61.

[0079] With the above structure, the positioning slot 61 provides a precise guide path for the rocker connector 5, ensuring that the rocker connector 5 maintains linear motion when swinging up and down, and avoiding lateral deviation; the two positioning plates 6 and the positioning slot 61 work together to limit the extreme positions of the rocker connector 5's up and down swing, preventing it from exceeding the designed range of motion. By limiting the movement of the rocker connector 5, the positioning structure helps maintain stability.

[0080] Specifically, in this embodiment, the positioning plate 6 and the fixed bracket 11 can be integrally formed or detachably connected. Of course, the positioning plate 6 and the fixed bracket 11 can also be slidably connected to facilitate the replacement or adaptation of the swing spring 53 of the swing connector 5 with different widths.

[0081] In this embodiment of the invention, the working process of the above-mentioned vibration core is as follows:

[0082] The crankshaft swing actuator 3 is driven to rotate by the direct drive motor 2. The crankshaft swing actuator 3 drives the swing connector 5 to swing, ultimately achieving the purpose of driving the vibration bracket 12 of the rhythm frame 1 to vibrate. The fixed bracket 11 and the vibration bracket 12 of the rhythm frame 1 can be connected by the connecting spring 13, the connecting spring 14, or the hinged boom 16. The connection structure of the connecting spring 13 and the connecting spring 14 can either allow the fixed bracket 11 to support the vibration bracket 12 or suspend the vibration bracket 12. The hinged boom 16 can only suspend the vibration bracket 12.
