Utility Model Content

[0004] This utility model provides a novel electromagnetic drive mechanism, the main purpose of which is to overcome the problem of complex structure of existing electromagnetic drive mechanisms.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A novel electromagnetic drive mechanism includes at least one drive assembly. The drive assembly includes a fixed base, a winding drum, and a movable iron rod. The movable iron rod is movably inserted into the fixed base. The winding drum is fixedly connected to the rear end of the fixed base. The rear part of the movable iron rod is located inside the winding drum. The front end of the movable iron rod extends out of the front end of the fixed base. The front end of the movable iron rod is connected to a transmission assembly. An electromagnetic coil is wound around the outer circumference of the winding drum. The electromagnetic coil is controlled by a controller.

[0007] Furthermore, the fixed base is provided with at least one set of limiting components, which form a limiting channel that restricts the movable iron rod to move only forward and backward.

[0008] Furthermore, the limiting component includes two vertical plates arranged symmetrically on the left and right, the two vertical plates are fixedly connected in the fixed base, and two limiting rollers arranged vertically are provided between the two vertical plates. The two limiting rollers are rotatably arranged and form the limiting channel between the two limiting rollers. The movable iron rod is located between the two limiting rollers and is in contact with the two limiting rollers.

[0009] Furthermore, the limiting roller is provided with two rubber rings on its outer periphery. The two rubber rings are located on the outer periphery of both ends of the limiting roller, and the two rubber rings are in contact with the moving iron rod.

[0010] Furthermore, the limiting component is provided in two sets, with the two sets of limiting components arranged one in front of the other.

[0011] Furthermore, the movable iron rod has a collar on its outer periphery, and the collar has multiple protrusions on its outer periphery. Each protrusion has a placement groove, and each placement groove has a rotatable friction roller. The movable iron rod abuts against the friction roller. The fixed base has a slotted photoelectric sensor. The collar has a slotted sensing piece that passes through the slotted photoelectric sensor on its outer periphery. The slotted photoelectric sensor is connected to the controller. The fixed base has a limiting groove for limiting the movement distance of the collar.

[0012] Furthermore, a reinforcing plate is fixedly connected to the top surface of the fixing base, and an end plate is fixedly provided at the rear end of the winding drum, with the top of the end plate fixedly connected to the rear end of the reinforcing plate.

[0013] Furthermore, the drive assembly is provided in two sets, which are arranged left and right. A connecting rod is fixedly connected between the front ends of the moving iron rods of the two sets of drive assemblies, and the transmission assembly is fixedly connected to the middle of the front end of the connecting rod.

The rear end of the first hinge plate is hinged to the fisheye bearing, and the bottom of the second hinge plate is hinged to the front end of the first hinge plate.

[0016] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following advantages: The controller can control the electromagnetic coil to alternately generate current in different directions, thereby causing the electromagnetic coil to generate magnetic fields in different directions. The magnetic fields in different directions can drive the moving iron rod to move forward and backward. The moving iron rod then drives the swinging device that can swing forward and backward through the transmission component. Compared with the existing electromagnetic drive mechanism, the structure of this utility model is simpler. Only an electromagnetic coil, a moving iron rod, and a transmission component are needed to constitute the electromagnetic drive mechanism, which also reduces the cost and weight of the electromagnetic drive mechanism.

[0028] Reference Figures 1 to 3 A novel electromagnetic drive mechanism includes at least one drive assembly. The drive assembly includes a fixed base 1, a winding drum 2, and a movable iron rod 3. The movable iron rod 3 is movably inserted into the fixed base 1. The winding drum 2 is fixedly connected to the rear end of the fixed base 1. The rear part of the movable iron rod 3 is located inside the winding drum 2, and the front end of the movable iron rod 3 extends out from the front end of the fixed base 1. A transmission assembly 4 is connected to the front end of the movable iron rod 3. An electromagnetic coil 5 is wound around the outer circumference of the winding drum 2, and the electromagnetic coil 5 is controlled by a controller. The fixed base 1 includes a base body 14 and a cover 15 locked to the top of the base body 14.

[0029] Reference Figure 1 , Figure 3 and Figure 4The fixed base 1 is provided with at least one set of limiting components 6, which form a limiting channel that restricts the movement of the movable iron rod 3 to only move back and forth. The limiting component 6 includes two vertical plates 61 arranged symmetrically from left to right. The two vertical plates 61 are fixedly connected to the fixed base 1. Two limiting rollers 62 are arranged vertically between the two vertical plates 61, and the two limiting rollers 62 are rotatably mounted. The limiting channel is formed between the two limiting rollers 62, and the movable iron rod 3 is located between and in contact with the two limiting rollers 62. The fixed base 1 is provided with a placement groove 11 for placing the vertical plates 61. The vertical plates 61 are fixed in the placement groove 11. Each end of the limiting roller 62 has a shaft portion 63, and each of the two vertical plates 61 has a shaft hole 64. The shaft portions 63 at both ends of the limiting roller 62 are located within the shaft holes 64 of the two vertical plates 61. Two rubber rings 65 are provided on the outer periphery of the limiting roller 62. The two rubber rings 65 are located on the outer periphery of both ends of the limiting roller 62 and are in contact with the moving iron rod 3. The two limiting rollers 62 of each set of limiting components 6 are used to limit the moving iron rod 3, so that the moving iron rod 3 can only move along a horizontal straight line. The contact between the rubber rings 65 and the moving iron rod 3 can reduce the noise of the moving iron rod 3 when it moves. In this embodiment, there are two sets of limiting components 6, which are arranged one after the other. The two sets of limiting components 6 can better ensure the straightness of the moving iron rod 3 when it moves in a horizontal straight line.

[0030] Reference Figure 3 and Figure 4 The movable iron rod 3 has a collar 7 on its outer periphery. The collar 7 has two protrusions 71 on its outer periphery, each protrusion 71 having a placement groove 72. Each placement groove 72 contains a rotatable friction roller 73. The movable iron rod 3 abuts against the friction roller 73. A slotted photoelectric sensor 12 is installed inside the fixed base 1. A slotted sensing plate 74 passes through the slotted photoelectric sensor on the outer periphery of the collar 7. The slotted photoelectric sensor 12 is connected to a controller. The fixed base 1 has a limiting groove 13 for restricting the movement distance of the collar 7. Four connecting posts 75 are provided on the outer periphery of the collar 7. A buffer rubber ring 76 is fixedly connected to the outer periphery of each connecting post 75. When the collar 7 moves forward and backward with the movable iron core 3, the buffer rubber ring 76 provides cushioning against collisions between the collar 7 and the sidewall of the limiting groove 13.

[0031] Reference Figure 1 and Figure 3A reinforcing plate 8 is fixedly connected to the top surface of the fixing base 1. Specifically, the reinforcing plate 8 is connected to the top surface of the base cover 15. An end plate 21 is fixedly provided at the rear end of the winding drum 2. The top of the end plate 21 is fixedly connected to the rear end of the reinforcing plate 8. The front end of the winding drum 2 is connected to the fixing base by bolts, and the top of the rear end of the winding drum 2 is connected to the reinforcing plate 8 by bolts. In this way, both the front and rear ends of the winding drum 2 can be fixed.

[0032] Reference Figure 1 and Figure 5 The transmission assembly 4 includes a first connecting member 41, a transmission member 42, and a second connecting member 43. The first connecting member 41 is U-shaped with its opening facing forward. The transmission member 42 is arranged horizontally, and the second connecting member 43 is arranged vertically. The front end of the first connecting member 41 is fixedly connected to the front end of the movable iron rod 3. The bottom of the second connecting member 43 is U-shaped with its opening facing downward. The front end of the transmission member 42 is hinged to the opening at the bottom of the second connecting member 43, and the rear end of the transmission member 42 is hinged to the opening of the first connecting member 41. The second connecting member 43 is fixedly connected to the transmission rod of a swing device 10. The swing device 10 is an existing device, and its specific structure will not be described in detail here.

[0033] Reference Figures 1 to 5 The working principle of this utility model is as follows: The controller can control the electromagnetic coil 5 to generate current in different directions, thereby causing the electromagnetic coil 5 to generate magnetic fields in different directions. When the electromagnetic coil 5 generates a magnetic field that attracts the movable iron core 3 to move backward, the movable iron core 3 drives the swing device 10 to swing backward through the first connecting member 41, the transmission member 42, and the second connecting member 43; when the electromagnetic coil 5 generates a magnetic field that pushes the movable iron core 3 to move forward, the movable iron core 3 drives the swing device 10 to swing forward through the first connecting member 41, the transmission member 42, and the second connecting member 43. This cycle can realize the back-and-forth swing of the swing device.

[0034] When the movable iron rod 3 is provided with a collar 7 on its outer periphery and a slotted photoelectric sensor 12 is provided in the fixed base 1, when the movable iron rod 3 moves, the collar 7 will move forward and backward due to friction and the weight of the collar 7 itself when it comes into contact with the friction roller 33. For example, when the movable iron rod 3 moves forward, the slotted photoelectric sensor 12 senses the sensing information of the sensing plate 74. At this time, the controller controls the electromagnetic coil 5 to be energized, so that the movable iron rod 3 moves forward. When the sensing plate 74 has completely passed the slotted photoelectric sensor 12, the slotted photoelectric sensor 12 can no longer sense the sensing information of the sensing plate 74. At this time, the controller controls the electromagnetic coil 5 to change the current direction, so that the movable iron rod 3 moves backward until the slotted photoelectric sensor 12 can no longer sense the sensing information of the sensing plate 74. Then the controller controls the electromagnetic coil 5 to change the current direction again, so that the movable iron rod 3 moves forward again. Repeating the above actions will enable the moving iron rod 3 to move back and forth. By sensing the sensing plate 74 through the slotted photoelectric sensor 12, the controller can more accurately control the timing of the electromagnetic coil 5 generating current in different directions.

The first hinge plate 45 is arranged horizontally, and the second hinge plate 46 is arranged vertically. The fisheye bearing 44 is fixedly connected to the front end of the movable iron rod 3. The rear end of the first hinge plate 45 is hinged to the fisheye bearing 44, and the bottom of the second hinge plate 46 is hinged to the front end of the first hinge plate 45. The working principle of the fisheye bearing 44, the first hinge plate 45, and the second hinge plate 46 is the same as that of the first connecting member 41, the transmission member 42, and the second connecting member 43 in Embodiment 1, and will not be described again here.
