[0031] Example 1

[0032] See Figures 1 to 3 As shown, the electromagnetic drive device for the photoelectric rocking chair includes a base plate 1, a reel coil 2 on the base plate 1, and a support assembly 3 coaxial with the reel coil on the base plate 1 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. The drive core 4 has a scale mark 40. The support housing 30 has a window 302, and fixing posts 303 are provided on the surface of the support housing on both sides of the window 302. The device also includes a photoelectric switch 5 connected to the fixing post, which is used to identify the scale mark.

[0033] This invention improves the electromagnetic drive device by adding a photoelectric switch and a scale mark. The motion state of the drive core rod is identified through the cooperation of the photoelectric switch and the scale mark, making the detection more direct and enabling more precise control of the electromagnetic drive device. This overcomes the problems of potential errors and numerous variables in indirect detection in the prior art. Furthermore, the above improvements simplify the detection structure of the electromagnetic drive device, thereby reducing the manufacturing cost of the electromagnetic drive device and correspondingly reducing the cost of the electric rocking chair with this electromagnetic drive device.

[0034] The mounting housing 30 has auxiliary support components 31 at both ends. Each auxiliary support component 31 includes an arc-shaped support plate 310 evenly distributed along the edge of the support hole. Each end of the arc-shaped support plate 310 has a support plate 311. The support plates on adjacent arc-shaped support plates 311 are arranged in parallel. An auxiliary guide wheel 312 is provided between the support plates 311. The auxiliary guide wheel is in close contact with the drive core rod. This improves the structure of the mounting housing by using the auxiliary guide wheel to support the drive core rod, reducing wear between the drive core rod and the support hole, and extending the service life of the equipment.

[0035] The support hole 301 is divided into three equal parts by arc support plates 311. One auxiliary guide wheel 312 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. The two auxiliary guide wheels are symmetrically arranged. Specifically, the present invention has three auxiliary guide wheels to support the drive mandrel, making the movement of the drive mandrel smoother. The drive mandrel and the auxiliary guide wheels roll together, reducing the resistance during the movement of the drive mandrel.

[0036] The aforementioned drum coil 2 includes a drum 20 and upright plates 21 set 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 surface of the drum 20 is wound with a coil. We generate an electromagnetic field by passing current through the coil to drive the drive core rod to move back and forth, thereby driving the rocking chair to rock and meet people's usage needs.

[0037] See Figure 1 As shown, the drive core rod 4 has a connecting ear 40 at the end near the support component. A transition connecting plate 41 is hinged to the connecting ear 40. The other end of the transition connecting plate 41 is hinged to a fixed connecting plate 42 that is connected to the seat. This utility model realizes the connection between the drive core rod and the seat through the above components. The transition connecting plate is hinged to the connecting ear and the fixed connecting plate to meet the driving requirements during the rocking chair's movement.

[0038] In this embodiment, see Figure 4As shown, the scale markings 40 are recesses 401 spaced apart on the surface of the drive core rod. Specifically, recesses are machined downwards at intervals on the surface of the drive core rod, forming light and dark areas at intervals on the surface of the drive core rod. The scale markings correspond to the photoelectric switch. During the movement of the drive core rod, the photoelectric switch determines the movement state of the drive core rod by recognizing the scale markings, thereby facilitating and quickly detecting the drive core rod.

[0039] Example 2

[0040] The scale markings in this embodiment differ from those in Embodiment 1; see [link / reference]. Figure 5 As shown, the scale marking 40 in this embodiment represents a detection area with continuous light and dark intervals formed on the surface of the driving mandrel. We can form this continuous light and dark interval detection area on the surface of the driving mandrel in various ways. For example, a carrier strip can be set on the surface of the workpiece, with light and dark detection areas spaced apart on the carrier strip. Alternatively, reflective and non-reflective areas can be machined on the workpiece surface. For instance, a non-reflective area can be obtained through partial electroplating, and a reflective area can be obtained through partial polishing. This allows the light and dark interval detection area to be identified during photoelectric switch detection, thus meeting the detection requirements.

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

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

[0043] This invention improves the electromagnetic drive device by adding a photoelectric switch and a scale mark. The motion state of the drive core rod is identified through the cooperation of the photoelectric switch and the scale mark, making the detection more direct and enabling more precise control of the electromagnetic drive device. This overcomes the problems of potential errors and numerous variables in indirect detection in the prior art. Furthermore, the above improvements simplify the detection structure of the electromagnetic drive device, thereby reducing the manufacturing cost of the electromagnetic drive device and correspondingly reducing the cost of the electric rocking chair with this electromagnetic drive device.

[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.
