Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an adjustable swing motor device. Background Technology

[0002] A swing motor is a device that converts electrical energy into mechanical swinging motion, with its output shaft capable of periodic reciprocating rotation within a specific angular range. Compared to traditional continuous rotary motors, swing motors, due to their unique motion characteristics, are widely used in many fields such as household appliances, automotive windshield wipers, and swing probes in medical equipment.

[0003] Currently, the main technical solutions for achieving oscillating motion in rocking motors are mechanical transmission and electromagnetic direct drive. Mechanical transmission rocking motors convert continuous rotation into oscillating motion by combining traditional rotary motors with mechanical transmission components such as gear sets, cam mechanisms, or crank connecting rods. Their drawbacks include complex mechanical structures, large size, difficulty in meeting miniaturization requirements, and a fixed, non-adjustable oscillation amplitude. Electromagnetic direct drive rocking motors directly drive the oscillation through electromagnetic coupling between the stator and mover. Their drawbacks include high manufacturing costs; the oscillation angle is limited by the electromagnetic field distribution, making large-angle, high-precision control difficult; and heat dissipation is difficult, with significant temperature rise under continuous load, affecting lifespan.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1-11 As shown, this utility model provides an adjustable swing motor device, which includes a motor 1 and a gearbox 2. A motor base 3 is provided between the motor 1 and the gearbox 2. The motor base 3 is used for connecting and fixing the motor 1 and the gearbox 2, and at the same time facilitates the disassembly and maintenance of the motor.

[0031] The gearbox 2 includes a housing 21 and a cover 22, which together form a closed chamber. Inside the chamber are a drive turbine 4, a drive worm gear 5, a rocking shaft 6, and a telescopic connecting rod 7. The drive worm gear 5 is fixedly connected to the output end of the motor 1. The drive turbine 4 meshes with the drive worm gear 5. The transmission ratio between the drive turbine 4 and the drive worm gear 5 is 40:1-60:1. The rocking shaft 6 is connected to the drive turbine 4 via the telescopic connecting rod 7. The motor 1 drives the drive worm gear 5 to rotate, and the drive worm gear 5 drives the drive turbine 4 to rotate. The drive turbine 4 drives the rocking shaft 6 to reciprocate through the telescopic connecting rod 7.

[0032] The side wall of the housing 21 is provided with an output turntable 211 and a turbine shaft hole 212. The output turntable 211 is used for the installation and fixation of the swing shaft 6, and the stability of the swing shaft 6 is enhanced by the protruding structure of the output turntable 211. The turbine shaft hole 212 is used to drive the rotation and fix the turbine 4.

[0033] The box cover 22 is used to seal the box body 21. An adjustment port 221 is provided on one side of the box cover 22. An adjustment cover 222 is installed on the adjustment port 221. The adjustment port 221 is used to adjust the length of the telescopic connecting rod 7, thereby adjusting the swing amplitude of the swing shaft 6.

[0034] The drive turbine 4 is rotatably connected to the housing 21 of the gearbox 2 via a turbine shaft and bearings. An eccentric shaft 41 is provided on the end face of the drive turbine 4, which is used to connect one end of the telescopic connecting rod 7.

[0035] The swing shaft 6 includes a swing shaft 61, a swing connecting plate 62, and a connecting shaft 63. The swing shaft 61 and the connecting shaft 63 are respectively fixedly and perpendicularly to the swing connecting plate 62. The swing shaft 61 and the connecting shaft 63 are located at both ends of the swing connecting plate 62. The swing shaft 61 is rotatably connected to the housing 21 through the output turntable 211 and the bearing. The connecting shaft 63 is connected to the eccentric shaft 41 through the telescopic connecting rod 7.

[0036] Since the drive turbine 4 is equipped with an eccentric shaft 41, the eccentric shaft 41 is connected to the connecting shaft 63 of the swing shaft 6 through the telescopic connecting rod 7. The swing shaft 61 of the swing shaft 6 is rotatably connected to the housing 21 through the output turntable 211, bearings, and the housing 21. The distance between the eccentric shaft 41 and the turbine shaft is less than the distance between the connecting shaft 63 and the swing shaft 61. When the motor 1 drives the drive worm 5 to rotate, the drive worm 5 drives the drive turbine 4 to rotate. One end of the telescopic connecting rod 7 rotates around the turbine shaft of the drive turbine 4 with the eccentric shaft 41, and the other end of the telescopic connecting rod 7 reciprocates around the center line of the swing shaft 61, thereby realizing the reciprocating swing of the swing shaft 61 driven by the motor 1.

[0037] The telescopic link 7 includes a first link 71 and a second link 72, which are connected by an adjusting screw 73. The front end of the first link 71 is provided with an eccentric shaft hole 711 for mounting an eccentric shaft 41. The eccentric shaft 41 is rotatably connected to the first link 71 through the eccentric shaft hole 711. The rear end of the first link 71 is provided with a link slide groove 712. The middle part of the first link 71 is provided with a screw limiting plate 713, and the middle part of the screw limiting plate 713 is provided with a limiting hole 714.

[0038] The front end of the second connecting rod 72 is provided with a connecting rod slide post 721, which is slidably connected to the connecting rod slide groove 712. The rear end of the second connecting rod 72 is provided with a connecting shaft hole 722, which is used for the installation of the connecting shaft 63. The connecting shaft 63 is rotatably connected to the second connecting rod 72 through the connecting shaft hole 722. The middle part of the second connecting rod 72 is provided with a screw connecting plate 723, and the middle part of the screw connecting plate 723 is provided with a screw shaft hole 724.

[0039] The adjusting screw 73 includes an internal hexagon nut, a straight rod section, and a threaded rod section. The adjusting screw 73 is connected to the first connecting rod 71 and the second connecting rod 72 through a screw limiting plate 713 and a screw connecting plate 723. The straight rod section of the adjusting screw 73 is rotatably connected to the screw limiting plate 713, and the threaded rod section of the adjusting screw 73 is threadedly engaged with the screw connecting plate 723. When the adjusting screw 73 is rotated using an internal hexagon wrench, the first connecting rod 71 and the second connecting rod 72 perform telescopic movements under the limiting action of the connecting rod slide groove 712 and the connecting rod slide post 721, thereby realizing the adjustment of the length of the telescopic connecting rod 7.

[0040] Since the drive turbine 4 drives the swing shaft 6 to swing back and forth through the telescopic link 7, the swing amplitude of the swing shaft 6 can be adjusted by adjusting the length of the telescopic link 7. In order to facilitate the adjustment of the length of the telescopic link 7, an adjustment port 221 is provided on one side of the box cover 22, and an adjustment cover 222 is installed on the adjustment port 221.

[0041] This invention provides an adjustable swing motor device, including a motor 1, a gearbox 2, and a motor base 3. The gearbox 2 internally houses a drive turbine 4, a drive worm gear 5, a swing shaft 6, and a telescopic connecting rod 7. The motor 1 drives the drive worm gear 5 and the drive turbine 4 to rotate. The drive turbine 4 drives the swing shaft 6 to reciprocate through the telescopic connecting rod 7. The telescopic connecting rod 7 includes a first connecting rod 71 and a second connecting rod 72. Adjusting the screw 73 allows for adjustment of the relative telescopic movement of the first connecting rod 71 and the second connecting rod 72, thereby adjusting the length of the telescopic connecting rod 7 and thus the swing amplitude of the swing shaft 6. This design is simple in structure, small in size, meets miniaturization requirements, has low manufacturing costs, and offers adjustable swing amplitude to meet various swing amplitude needs.
