[0030] Example 1

[0031] See Figure 1As shown, the electromagnetic drive device for the rocking chair includes a base plate 1, on which a reel coil 2 is mounted. A support assembly 3, coaxial with the reel coil 2, is located on the base plate next to the reel coil 2. The support assembly 3 includes a support housing 30 with a support hole 301, and a drive core 4 inserted into the support hole and extending into the reel coil. A mounting housing 31 is located at the top of the support housing 30, and a connecting hole 310 is located at the bottom of the mounting housing 31, allowing communication between the mounting housing 31 and the support hole 301. Support seats 311 are located on both sides of the mounting housing 31 on the connecting hole 310. The upper end of 1 is provided with a bearing groove 3110, and also includes a detection wheel 32. The support shafts 320 on both sides of the detection wheel 32 are installed in the bearing groove 3110. The detection wheel 32 passes through the connecting hole and is in close contact with the surface of the drive core rod. A detection circuit board 35 is also provided in the mounting housing 31. The detection circuit board is provided with a detection sensor to monitor the movement of the detection wheel. Specifically, the detection circuit board is set in the mounting housing. The detection sensor can be used in various ways, such as a through-beam photoelectric switch or a Hall sensor. The detection sensor monitors the back-and-forth movement of the detection wheel. It also includes a cover plate 33, which is fixedly connected to the upper end of the mounting housing.

[0032] This utility model relates to an electromagnetic drive device. The electromagnetic drive device uses electromagnetic force to drive a drive core rod to move back and forth, thereby causing the seat to swing back and forth, achieving the rocking motion of a rocking chair and meeting people's usage needs. This utility model improves the detection method of the electromagnetic drive device, mainly by using a detection wheel that is in close contact with the drive core rod for detection. When the drive core rod moves back and forth under the drive of the drum coil, it drives the detection wheel to rotate. By detecting the direction and speed of the detection wheel's rotation, the electromagnetic drive device can be controlled, ensuring the detection accuracy of the electromagnetic drive device and better driving the rocking chair. Furthermore, the above-mentioned detection device also reduces the cost of the electromagnetic drive device, thereby reducing the cost of the rocking chair, as it eliminates the need for high-cost sensors to detect parameters such as the rocking chair's angular velocity.

[0033] See Figure 3 and Figure 5As shown, the inner wall of the mounting housing 30 is provided with a V-groove 34, and the support shaft of the detection wheel is fitted into the V-groove. The lower surface of the cover plate 33 is provided with two clamping blocks 330, and the lower surface of the clamping blocks is provided with clamping grooves 3301. The clamping grooves rest on the support shaft. The V-groove serves as a guide. When the detection wheel is assembled into the mounting housing, the support shaft of the detection wheel moves downward along the V-groove. The upper opening of the V-groove is large, which facilitates the quick entry of the support shaft. The V-groove has a structure that is larger at the top and smaller at the bottom. The bottom of the V-groove can limit the support shaft. At the same time, the clamping blocks on the cover plate limit it in the vertical direction, thereby ensuring that the detection wheel can stably and reliably contact the drive core rod after installation.

[0034] The cover plate 33 is provided with a wire outlet hole 331, which facilitates external wiring.

[0035] See Figure 4 As shown, both ends of the mounting housing 30 are provided with auxiliary support components 34. The auxiliary support components 34 include arc support plates 340 evenly distributed along the edge of the support hole. Both ends of the arc support plates 340 are provided with support plates 341. The support plates 341 on adjacent arc support plates are arranged in parallel. An auxiliary guide wheel 342 is provided between the support plates. The auxiliary guide wheel 342 is in close contact with the drive core rod. This utility model uses auxiliary support components to support the drive core rod, reducing wear between the drive core rod and the inner wall of the mounting housing.

[0036] The edge of the connecting hole is divided into three equal parts by arc-shaped support plates.

[0037] One auxiliary guide wheel is located directly above the drive mandrel, and the other two auxiliary guide wheels are located on both sides of the lower part of the drive mandrel, with the two auxiliary guide wheels arranged symmetrically.

[0038] The positions of each auxiliary guide wheel are defined here. The auxiliary guide wheels located on both sides at the bottom can balance the force in the horizontal direction, and there is only the force in the vertical direction, which is shared by the two auxiliary guide wheels. This reduces the force on each auxiliary guide wheel and helps to extend the service life of the equipment.

[0039] The aforementioned drum coil 2 includes a drum 20 and upright plates 21 at both ends of the drum. The drum and the upright plates are integrally formed. The lower end of the upright plate 21 is fixedly connected to the base plate 1. The lower end of the upright plate has a horizontal edge with a through hole. Fasteners pass through the through hole to fix the upright plate to the base plate, thereby fixing the drum coil to the base plate. The surface of the drum 20 is wound with a coil. By energizing the coil, a magnetic field is generated. The magnetic field drives the drive core rod to move on the axis of the drive housing, thereby driving the seat to swing.

[0040] The drive core rod 4 has a connecting ear 40 at the end near the support component. A threaded hole is provided on the axis of the drive core rod. The connecting ear is fixedly connected in the threaded hole. A transition connecting plate 41 is hinged to the connecting ear 40. A fixed connecting plate 42 connected to the seat is hinged to the other end of the transition connecting plate 41. The connection between the drive core rod and the rocking chair body is realized through the above structure.

[0041] An electrically driven rocking chair includes the aforementioned electromagnetic drive device for rocking chairs.

[0042] In summary, this utility model has the following beneficial effects:

[0043] This invention improves the detection method of the electromagnetic drive device. It mainly uses a detection wheel that is in close contact with the drive core rod for detection. When the drive core rod moves back and forth under the drive of the drum coil, it drives the detection wheel to rotate. By detecting the direction and speed of the rotation of the detection wheel, the electromagnetic drive device can be controlled, ensuring the detection accuracy of the electromagnetic drive device and enabling better driving of the rocking chair. In addition, the detection device also reduces the cost of the electromagnetic drive device, thereby reducing the cost of the rocking chair, as there is no need to use high-cost sensors to detect parameters such as the angular velocity of the rocking chair.

[0044] Based on the described 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.
