[0001] The present invention relates to the application of magnetic composite materials, and in particular to a hybrid power motion unit, a hybrid power structure and a demonstration system thereof. Background Art

[0002] Energy shortage and rational utilization are eternal topics facing contemporary society. Electric, pneumatic, oil-powered and hybrid power are booming in the automotive industry. How to adopt various hybrid power in the toy car industry to achieve lower energy consumption, more complex movement and controllability is also a difficult problem to solve.

[0003] In the prior art, the complexity of the motion that can be achieved while satisfying dynamic balance varies due to the different motion trajectories, different motion speeds, and the ever-changing force modes of moving objects and the differences in different energy drive modes.

[0004] Publication (Announcement) No. CN209519347U discloses a magnetic levitation train toy comprising several train sections and tracks. The tracks are provided with levitation magnetic strips. A levitation magnetic block is mounted on the bottom of each train section, with the north pole of the levitation magnetic block directly above the north pole of the levitation magnetic strip, and the south pole of the levitation magnetic block directly above the south pole of the levitation magnetic strip. Vertical sidewalls are mounted above the sides of the tracks, each equipped with a drive magnetic strip that extends along the track. An electromagnetic coil is mounted within the train section, located on one side of the train section near the drive magnetic strip. The electromagnetic coil is equipped with a control circuit. Furthermore, a microprocessor and a Hall effect sensor are mounted within the train section, connected to the microprocessor, which in turn is connected to the control circuit of the electromagnetic coil. This utility model features an ingenious mechanism for driving the toy train, enabling forward and backward movement, and precise and rapid acceleration and deceleration.

Summary of the Invention

[0005] The present invention discloses a hybrid power motion unit, a hybrid power structure and a demonstration system thereof. Through structural settings, the system utilizes direct current power, the adsorption force and repulsion force between permanent magnets, the mechanical friction force, gravity, centrifugal force and centripetal force during the motion process to achieve vertical up and down motion of the hybrid power motion unit, inner and outer arc motion at various angles of a three-dimensional circle, horizontal inverted motion, sideways motion and other complex motion modes. Users can be inspired by their understanding of various dynamic phenomena during the play process, and think about dynamics-related issues, such as how to achieve the rational use of hybrid power and demonstrate more complex motions with lower energy consumption.

[0006] A hybrid power unit comprising:

[0007] A permanent magnetic ring, which is magnetized in the thickness direction and fixed to one end of the central axis;

[0008] A coreless micro DC motor is connected to the central axis of the permanent magnet ring through a transmission mechanism.

[0009] Also includes:

[0010] An annular structural member is fixed on the central axis and closely relies on the upper end of the permanent magnetic ring. Saw teeth are set in the thickness direction of the outer periphery, and the maximum radius of the saw teeth is not greater than the radius of the permanent magnetic ring.

[0011] Also includes:

[0012] There are three accommodating cavities, which are arranged in a line. The accommodating cavities on both sides respectively place a set of the hollow cup micro DC motor and its transmission device, and the middle accommodating cavity places a button battery and a switch for the DC motor. The permanent magnetic ring and the annular structural member are respectively arranged under the accommodating cavities on both sides.

[0013] The three accommodating chambers are connected by a non-detachable movable shaft hole connection. The middle accommodating chamber is provided with a protruding horizontal axis on the adjacent surface, and the accommodating chambers on both sides are provided with two protruding through holes at positions matching the horizontal axis of the middle accommodating chamber, and the diameter of the through holes is larger than the diameter of the horizontal axis.

[0014] The permanent magnetic ring is an injection-molded or die-molded samarium iron nitrogen magnetic ring, or a die-molded or sintered neodymium iron boron magnetic ring.

[0015] A hybrid power structure comprising:

[0016] At least one of the above hybrid sports units;

[0017] A spliced track comprising at least two track units and connectors on their backs, the three being detachably fixedly connected; flexible permanent magnetic strips with identical vertically aligned magnetic poles are installed in the side walls of both sides of the track units, with the lower edges of the magnetic strips away from the bottom of the track, and the flexible permanent magnetic strips are magnetized on both poles of the inner surface plane;

[0018] The hybrid motion unit is placed in the spliced track, the magnetic strips in the permanent magnetic ring and the side walls of the track unit have opposite vertical poles, and the horizontal gap between the magnetic ring and the track side wall is 1-8 mm.

[0019] Also includes:

[0020] The support body comprises at least one support unit in the vertical direction: two vertical double connecting columns of equal height and two upper and lower connecting pieces, which are detachably fixedly connected to each other.

[0021] The connector is provided with a first protruding mechanism on the outside on both sides that matches the vertical double connecting columns to build the connection of the support unit itself; one side of the connector is also provided with a second protruding mechanism on the inside that matches the through hole of the track unit to build the connection with the track unit.

[0022] The spliced track includes straight track units with track side walls vertically upward, vertically downward, horizontally, and laterally, inner arc or outer arc track units with track side walls that are part of a three-dimensional circle at various angles, and at least one track unit with other irregular shapes and various angles.

[0023] The side walls of the track unit are horizontal, the lateral straight track unit, the track side walls are in the form of inner arc or outer arc of a part of a three-dimensional circle at various angles, and the edges of the side walls of the track unit on both sides are provided with serrations matching the thickness direction of the outer circumference of the annular structure.

[0024] A hybrid power demonstration system comprises a roller coaster toy having any of the above hybrid power structures.

[0025] Beneficial effects

[0026] One source of hybrid power is that the magnetic rings and the magnetic strips in the two track sidewalls have opposite magnetic poles relative to each other. The result of the three attracting each other is that the hybrid motion unit leaves the bottom of the track, or drives the permanent magnet ring to move and rotate, and also drives the coaxial annular structure to rotate, or hover on one side of the track sidewall. Although the permanent magnet ring and the annular structure rotate forward or backward, they are no longer wheels in the traditional sense and do not need to meet the requirement of supporting the overall gravity, which greatly reduces energy consumption.

[0027] The second source of hybrid power is that inside the track, a coreless DC micromotor drives the permanent magnet ring and the coaxial ring structure through a transmission device to rotate forward and backward synchronously. Because of the superposition of the above-mentioned magnetic rotation, the motor rotation load is greatly reduced, and energy consumption is greatly reduced;

[0028] The matching of the annular structure and its serrations with the partial track units and the serrations thereon helps the hybrid motion unit to complete various complex movements within the spliced track, especially vertical up and down movement and movement on the inner or outer arc tracks of a part of a three-dimensional circle at various angles;

[0029] In the hybrid demonstration system of Example 3 of the present application, the hybrid motion unit roller coaster, driven by a combination of electric and permanent magnetic energy, maintained an average speed of approximately 0.21 m / s under various complex track conditions. It did not fall off the top of the inner ring of the vertical circle, nor was it thrown off the top of the outer ring of the vertical circle. It could maintain motion or suspension on an inverted straight track or on a track at any lateral angle. When stopped at any location, it could eventually leave the bottom and stabilize on the inner side of the track after inertia.

[0030] The roller coaster of this embodiment has simple components, is easy to implement and mass-produce, has low production cost, and has a good market prospect.

[0049] The embodiments of the present application are described in detail below. It should be noted that the "first" and "second" mentioned herein are only used to distinguish technical features, and cannot be understood as indicating or implying the relative importance in time or the number of the indicated counting features or the order of the indicated technical features; "matching" means that the position, size, and shape are consistent with each other and can be assembled or connected; not greater than means equal to or less than; the magnetization in the thickness direction of the permanent magnetic ring refers to the axial magnetization with the magnetization direction parallel to the central axis. Example 1

[0050] Reference Figure 1 A schematic diagram of the structure of a hybrid motion unit in a specific embodiment, a hybrid motion unit 100, comprising: a permanent magnet ring 11 magnetized in the thickness direction, fixed to one end of its central axis; a coreless micro DC motor 12, connected to the central axis of the permanent magnet ring through a transmission mechanism, thereby driving the permanent magnet ring to rotate 12' around the central axis; an annular structure 13 fixed to the central axis, closely leaning against the upper end of the permanent magnet ring, with serrations 14 provided in the outer thickness direction, the maximum radius of the serrations being no larger than that of the permanent magnet ring; three accommodating cavities 16 arranged in a line, with the accommodating cavities on both sides respectively placing a set of the coreless micro DC motor and its transmission device 15, and the middle accommodating cavity placing a button battery and a switch for the DC motor; the annular structure and the permanent magnet ring are arranged closely above and below the accommodating cavities on both sides;

[0051] The permanent magnet ring selected in this embodiment has an outer diameter of 30 mm, an inner diameter of 18 mm, and a thickness of 5 mm. The permanent magnet ring is magnetized in the height direction, and the magnetic pitch is 2.5 mm. The maximum outer diameter of the annular structure is 30 mm, the inner diameter is 18 mm, and the thickness is 3.5 mm.

[0052] It is understandable that the switch can also be connected to a remote control setting; the button battery and switch can be adjusted according to the actual size of the accommodating cavity and the specific voltage, 2 button batteries in series for 3V, or 1 button battery for 3V. In this embodiment, 4 button batteries are used, and 3V is supplied to the hollow cup batteries on both sides after two buttons are connected in series.

[0053] The permanent magnetic ring is an injection-molded or compression-molded samarium iron nitrogen magnetic ring, or a compression-molded, injection-molded, or sintered neodymium iron boron or samarium cobalt magnetic ring. The surface magnetism of the permanent magnetic ring is 1800-5500Gs. In this embodiment, the permanent magnetic ring is a nickel-plated sintered neodymium iron boron magnetic ring with a surface magnetism of 3800Gs.

[0054] The coreless DC motor in the hybrid motion unit drives the permanent magnet ring to rotate. The permanent magnet ring is both a structural wheel and part of the magnetic power source, which is very different from traditional wheels.

[0055] The annular structure coaxial with the permanent magnet ring is driven to rotate by the DC motor and acts as a wheel to increase the friction required for the movement process. Its sawtooth structure helps the hybrid motion unit to complete various movements.

[0056] It is understandable that one of the sources of hybrid power is the drive of a coreless DC motor;

[0057] The three accommodating cavities are connected by a non-detachable movable shaft-hole connection 17. The middle accommodating cavity is provided with a horizontal axis on the adjacent surface, and the accommodating cavities on both sides are provided with two protruding through holes at positions matching the horizontal axis of the middle accommodating cavity. The diameter of the through hole in this embodiment is 0.25 mm larger than the diameter of the horizontal axis. It can be understood that the movable shaft-hole connection provides a basis for the fitting movement of the hybrid motion unit and the track arc surface, and can be deformed by squeezing or stretching the arc according to the shape of the outer arc or inner arc track unit. Example 2

[0058] Reference Figure 3a Schematic diagram of the connection structure of the support body, the splicing track, and the hybrid power motion unit in a specific embodiment, a hybrid power structure includes:

[0059] At least one of the above-mentioned hybrid motion units 100;

[0060] Splicing track 200, also refer to Figure 2a , comprising at least two track units 21 and a connector 31 on the back thereof, the three being detachably fixedly connected; identical flexible permanent magnetic strips 22' are installed in the side walls 22 on both sides of the track unit 21, and the magnetic strips are both magnetized with two poles on a single plane on the inner side of the track, and the magnetic sequence of the vertical poles is the same;

[0061] It is understood that the flexible permanent magnetic strip is one of rolled or extruded neodymium iron boron, samarium iron nitride, ferrite, and samarium cobalt magnetic strips. In this embodiment, an extruded flexible ferrite magnetic strip is selected, which has a height of 8 mm and a thickness of 4 mm. After installation, the surface magnetic field of the inner wall of the track reaches 550 Gs, and the bottom edge of the magnetic strip is 5.5 mm away from the bottom surface of the track.

[0062] Reference Figure 2g Schematic diagram of the magnet pole structure. The hybrid motion unit is placed in the spliced track. The permanent magnet ring and the magnetic strips on the side walls of the track unit have opposite vertical poles, and the three attract each other. The horizontal gap between the magnet ring and the side wall is 1-8mm.

[0063] It can be understood that the permanent magnet rings in the hybrid motion unit and the magnetic strips 22' in the side walls 22 of the track unit are mutually attracted to each other, allowing the hybrid motion unit to leave the bottom of the track, move forward and spin, move forward or backward within the track, or suspend against the side walls of the track. It can be seen that the movement modes of moving, stopping, suspending, and rotating achieved by the attraction between the permanent magnets are also one of the sources of hybrid power in this application.

[0064] See also Figure 2b-2f , the spliced track of this embodiment includes track units with track sidewalls that are vertically upward, vertically downward, or horizontally straight, and track units with track sidewalls that are inner arc or outer arc track units that are part of a three-dimensional circle at various angles;

[0065] This embodiment uses a track side wall height of 14.5mm, and the material can be at least one of acrylic, ABS, PU, PP, POM, PS, PE, and PVC;

[0066] In this embodiment, under the hybrid power of the motor and magnetic attraction, the permanent magnetic ring of the hybrid motion unit and the magnetic strips in the side walls of the track unit attract each other to achieve balance, and the bottom of the magnetic ring is more than 5.5 mm away from the bottom of the track, without having to bear gravity, and energy consumption is reduced; the motion unit moves forward, backward, or suspends next to the side wall in the track; the rotation, movement, and stop generated by the dynamic balance of magnetic attraction between the hollow cup micro DC motor driven rotation superimposed permanent magnetic strips and permanent magnetic rings greatly reduce energy consumption; at the same time, due to the existence of magnetic attraction, not only the annular structure is higher than the side wall of the track, but the three accommodating cavities are higher than the side wall of the track, and the hybrid motion unit will not fall due to the inverted state. It can be understood that the larger the surface magnetism of the flexible permanent magnetic strips and permanent magnetic rings, the stronger the magnetic attraction, the greater the spin drive of the motion unit, and the stronger the load-bearing capacity of the volume and weight of the three accommodating cavities;

[0067] The track sidewalls are horizontal and lateral linear track units, and the track sidewalls are in the form of inner arcs or outer arcs of a portion of a three-dimensional circle at various angles. The edges of the two sidewalls of the track unit are provided with saw teeth 24 that match the thickness direction of the outer circumference of the annular structure.

[0068] It is understandable that the mutually matching saw teeth also help the hybrid telecontrol unit to complete various vertical and three-dimensional arc movements.

[0069] A hybrid structure further includes: a support body 300, also referring to Figure 3b , an exploded view of the support unit of the support body, wherein the support body vertically comprises at least one support unit: two vertical double connecting columns 34 of equal height and two upper and lower connecting members 31, which are detachably fixedly connected to each other; the connecting member at least connects the track unit and one of the support units, thereby constructing the splicing track 200, the support body 300 itself and the connection between each other;

[0070] Reference Figure 3c Schematic diagram of the connecting member structure, the connecting member 31 is provided with a first protruding mechanism 32 on the outside that matches the vertical double connecting column on both sides to build the connection of the support unit itself; the connecting member is also provided with a second protruding mechanism 33 on the inside that matches the through hole 23 of the track unit on one side to build the connection with the track unit.

[0071] It is understandable that the unique double-sided connection design of the connector makes it possible to install the splicing track in two opposite directions, and also makes the movement of the hybrid motion unit more complex and diversified. Example 3
