Description

Technical Field

[0001] The present invention relates to the technical field of magnetic wheels, and more specifically, to a magnetic wheel device. Background Art

[0002] Traditional magnetic wheels usually use permanent magnets as adsorption materials, and the wheel body is adsorbed on the rotor through magnetic force. The magnetic force of this kind of magnetic wheel is uncontrollable, so the utilization rate of magnetic force is relatively low. This means that the magnitude of the magnetic force cannot be adjusted according to actual needs, so that traditional magnetic wheels cannot meet the different requirements of various application scenarios. For example, when a smaller magnetic force is required, traditional magnetic wheels may not be able to change the magnitude of the magnetic force. In order to make the wheel body move, the motor may consume too much electricity, which will have an adverse impact on the performance of the entire system. In addition, due to the non-adjustable magnetic force, traditional magnetic wheels may not meet the requirements in some specific application scenarios.

[0003] In addition, although electromagnets have a large magnetic force, their magnetism needs to rely on an external power supply to maintain. This means that the magnetic force stability of electromagnets is relatively poor, and there are also many inconveniences in use. For example, once the power supply fails or is interrupted, the electromagnet will not be able to work properly. In addition, the magnetic field of the electromagnet is easily affected by the ambient temperature. In a high-temperature environment, the working efficiency of the electromagnet may decrease significantly, and it may even cause the coil to overheat and burn out.

[0004] Therefore, traditional magnetic wheels and electromagnets may not meet the requirements in some application scenarios. To solve these problems, we propose a magnetic wheel with controllable magnetic force. This kind of magnetic wheel can adjust the magnitude of the magnetic force according to actual needs, thereby improving the utilization rate of the magnetic force. In addition, this kind of magnetic wheel does not require an external power supply to maintain magnetism, so its magnetic force stability is better and it is more convenient to use.

[0031] Figure 1 It is a schematic structural diagram of a magnetic wheel device according to an embodiment of the present invention. The magnetic wheel device includes:

[0032] A magnetic force control component, which includes a planetary gear unit, a magnet unit, and a first motor 101 transmission unit. The magnet unit is placed inside the planetary gear unit to form a wheel-like structure. An outer shell 207 is provided outside the wheel-like structure. The first motor transmission unit is axially connected to the planetary gear unit and the magnet unit to adjust the magnitude and position of the magnetic force;

[0033] A motion control component, which includes a second motor transmission unit. The second motor transmission unit is axially connected to the outer shell 207;

[0034] Among them, the outer shell 207 is not axially connected to the wheel-like structure to achieve independent operation of magnetic force control and power control.

[0035] Specifically, as Figure 4 shown, a sealing end cover 107 is provided at the part where the first motor transmission unit is axially connected to the planetary gear unit and the magnet unit, and a sealing end cover 107 is also provided at the part where the second motor transmission unit is axially connected to the outer shell 207 to prevent dust, dirt, etc. from invading the moving parts.

[0036] In one embodiment, the magnet unit includes a sector magnet 108, as Figure 5 shown, and the sector magnet 108 is provided with holes.

[0037] In one embodiment, as Figure 2 shown, the first motor 101 drive unit includes a first motor 101, a magnet rotating small pulley 102, a magnet rotating drive belt 103, a magnet rotating large pulley 104, a magnet rotating mandrel 105, and a first bearing 106. The first motor 101 drives the magnet rotating small pulley 102, and the magnet rotating small pulley 102 transmits power to the magnet rotating large pulley 104 through the magnet rotating drive belt 103, and the magnet rotating large pulley 104 then transmits the power to the magnet rotating mandrel 105.

[0038] In one embodiment, as Figure 3 shown, the second motor drive unit includes a second motor 201, a wheel rotating small pulley 202, a wheel rotating drive belt 203, a wheel rotating large pulley 204, a wheel cover flange coupling 205, and a second bearing 206. The second motor 201 drives the wheel rotating small pulley 202, and the wheel rotating small pulley 202 transmits power to the wheel rotating large pulley 204 through the wheel rotating drive belt 203, and the wheel rotating large pulley 204 then transmits the power to the wheel cover flange coupling 205.

[0039] In one embodiment, the magnet rotating mandrel 105 is in shaft drive connection with the sector magnet 108 to enable the first motor 101 drive unit to drive the sector magnet 108 to move.

[0040] In one embodiment, the wheel cover flange coupling 205 is in drive connection with the housing 207 to enable the second motor drive unit to drive the housing 207 to move.

[0041] In one embodiment, the first motor 101 drive unit is disposed on one side of the wheel-shaped structure, and the second motor drive unit is disposed on the other side of the wheel-shaped structure.

[0042] In one embodiment, as Figure 6 shown, the planetary gear unit includes a sun gear, a planet carrier 301, a gear 302, and a ring gear 304, and the gear 302 and the ring gear 304 are not in drive connection.

[0043] In one embodiment, the ring gear 304 is in drive connection with the housing 207 and the wheel cover flange coupling 205, and the gear 302 is in drive connection with the sector magnet 108 and the magnet rotating mandrel 105.

[0044] In one embodiment, two planetary gear units are provided. Each single planetary gear unit includes three gears 302. The sector magnet 108 is disposed between the two planetary gear units, and the sector magnet 108 and the gears 302 are fixed through holes.

[0045] Specifically, the magnetic wheel device includes two types of components:

[0046] Rotating assembly inside the sector magnet wheel: The first motor 101 is the power source of the rotating assembly inside the sector magnet wheel. Through the rotation of the first motor 101, force is transmitted to the magnet rotating small pulley 102, causing it to start rotating and introducing energy into the mechanical system. Immediately afterwards, the magnet rotating drive belt 103 intervenes in the movement, transmitting the power from the magnet rotating small pulley 102 to the magnet rotating large pulley 104. The magnet rotating drive belt 103 is tightly wrapped between the magnet rotating small pulley 102 and the magnet rotating large pulley 104 to ensure efficient energy transmission. The movement of the magnet rotating drive belt 103 starts the rotation of the magnet rotating large pulley 104. Along with the rotation of the magnet rotating large pulley 104, energy is transmitted to the magnet rotating core shaft 105. The magnet rotating core shaft 105 passes through the center of the magnet rotating large pulley 104. When the magnet rotating large pulley 104 rotates, the magnet rotating core shaft 105 also starts to rotate. Finally, the rotational movement of the magnet rotating core shaft 105 is transmitted to the sector magnet 108. By controlling the rotation of the sector magnet 108, the distance between the sector magnet 108 and the contact surface can be adjusted, thereby precisely controlling the magnitude of the magnetic force. Each component in the entire mechanical system collaborates precisely to ensure the accuracy and diversity of the movement inside the magnetic wheel.

[0047] Magnetic wheel movement assembly: The power of the entire system comes from the second motor 201. Through the rotational power of the second motor 201, it is transmitted to the wheel rotating small pulley 202, starting its rotation, which realizes the mechanical introduction of energy. Subsequently, the wheel rotating drive belt 203 intervenes in the movement, transmitting the power to the wheel rotating large pulley 204. The wheel rotating drive belt 203 is tightly wrapped between the wheel rotating small pulley 202 and the wheel rotating large pulley 204 to ensure efficient energy transmission. The movement of the wheel rotating drive belt 203 starts the rotation of the wheel rotating large pulley 204. As the wheel rotating large pulley 204 rotates, energy is transmitted to the wheel cover flange coupling 205. The wheel cover flange coupling 205 is connected to the housing 207 and moves together with the housing 207.

[0048] The rotation component inside the sector magnet wheel and the magnetic wheel movement component are independent of each other. The sector magnet 108 is restricted by two planetary gear units of the wheels and positioned by three synchronizing shafts 303. The rotation of the sector magnet 108 is achieved by the first motor 101, which ultimately affects the three gears 302. At the same time, the movement of the wheel achieved by the second motor 201 ultimately affects the gear ring 304 inside the wheel. It should be noted that the movement between the gear 302 and the gear ring 304 is a follow-up movement, and there is no active power transmission between them. This method provides excellent flexibility and adjustability. Users can optimize the magnetic force control system and the movement system respectively according to different application requirements to achieve the best performance.

[0049] The present invention has the following beneficial effects:

[0050] 1. Magnetic force controllability: The present invention adopts the design of a sector magnet. By simply adjusting the distance between the sector magnet and the contact surface, users can achieve precise control of the magnetic force. This design is not only convenient and practical but also can meet the requirements of various different application scenarios. For example, in occasions where a smaller magnetic force is required, the magnetic force can be weakened by reducing the distance between the sector magnet and the contact surface; while in occasions where a larger magnetic force is required, the distance between the two can be appropriately increased to enhance the magnetic force.

[0051] 2. Magnetic force efficiency: The sector magnet used in the present invention is a permanent magnet with high magnetic force characteristics. Compared with an electromagnet, a permanent magnet does not require an external power source to maintain its magnetism, so it has a higher energy efficiency ratio and a longer service life. In addition, since the magnetic field of a permanent magnet is relatively stable, it is not as easily affected by the ambient temperature as an electromagnet.

[0052] 3. Versatility: By separating the rotation inside the sector magnet wheel from the movement of the magnetic wheel, the present invention enables the magnetic wheel to be either magnetically controlled or the magnetic force remains unchanged during the movement of the magnetic wheel with an innovative design. The rotation part inside the magnet wheel and the movement part of the magnetic wheel are independent of each other, allowing users to flexibly adjust the magnitude of the magnetic force as needed and maintain the stability of the magnetic force during the movement of the magnetic wheel.
