Description

Technical Field

[0001] This invention belongs to the field of roller skating shoes and new energy technology, and specifically relates to a roller skating shoe. Background Technology

[0002] Roller skating has gradually become a popular recreational and fitness activity. To improve the intelligence and controllability of roller skating, people increasingly favor intelligent models with features such as location tracking, speed monitoring, and light or sound alerts. However, currently, these electronically controlled roller skating systems rely solely on batteries for power, unnecessarily increasing the size and weight of the skates. Most importantly, they are prone to losing some functions when the battery runs out during outdoor activities or long-distance skating. Therefore, there is an urgent need to develop roller skating systems capable of generating their own power, which would not only solve the power supply problem for their own intelligent systems but also charge portable electronic devices such as mobile phones. Summary of the Invention

[0003] This invention proposes a roller skating shoe, which mainly includes a shoe body, a wheel bracket, rollers and axles. The shoe body is mounted on the horizontal plate of the wheel bracket, the rollers are fitted on the axles, the axles are mounted on the vertical wall of the wheel bracket, and a circuit board and a power generation unit are mounted on the vertical wall of the wheel bracket. The power generation unit consists of a coil, an exciter and an inner shell.

[0004] The roller consists of a wheel body and a bushing. The wheel body is fitted onto the outer edge of the bushing via injection molding. The convex ring on the inner edge of the wheel body is embedded in the annular groove on the outer edge of the bushing. An actuator is embedded in the wheel body, consisting of one long or two short actuators. The two sets of actuators are evenly distributed on two different axial sections, and are located near the left and right sides of the wheel body, respectively. The actuator can be cubic, cylindrical, or spherical, and is made of ferromagnetic material, such as iron, cobalt, nickel, or a permanent magnet. When the actuator is a permanent magnet, its magnetic poles are arranged along the axial direction of the wheel body or along its circumference. The wheel body is made of rubber or plastic, while the bushing is made of non-ferromagnetic material, such as metal or high-strength plastic.

[0005] When the actuator is a permanent magnet and its magnetic poles are all arranged along the axial direction of the wheel body, the magnetic poles of two axially adjacent actuators in the two sets of actuators are arranged in the same direction, that is, the opposite magnetic poles of the two actuators are opposite to each other. The magnetic poles of two circumferentially adjacent actuators in the same set of actuators are arranged in opposite directions, that is, the opposite magnetic poles of the two actuators are located in the same axial section of the wheel body.

[0006] When the actuator is a permanent magnet and its magnetic poles are arranged along the circumferential direction of the wheel body, the magnetic poles of two axially adjacent actuators in the two sets of actuators are arranged in opposite directions, that is, the opposite magnetic poles of the two actuators are opposite to each other along the axial direction of the wheel body. The magnetic poles of two circumferentially adjacent actuators in the same set of actuators are arranged in the same direction, that is, the opposite magnetic poles of the two actuators are close to each other.

[0007] The axle consists of an axle body and studs at both ends of the axle body. The axle body and studs are an integral structure. The axle is made of a non-ferromagnetic material.

[0008] The roller is mounted on the axle body through the bushing hole and is axially positioned by two inner nuts, allowing the roller to rotate freely around the axle body. The two inner nuts are mounted on the studs at both ends of the axle body and abut against both sides of the axle body, with the roller located between the two inner nuts and able to rotate relative to them. The axle body is mounted on the vertical wall of the wheel bracket via two inner nuts and two outer nuts, with the studs at both ends of the axle body located in the slots of the two vertical walls of the wheel bracket body, and the inner and outer nuts press the axle body onto the vertical wall of the wheel bracket body.

[0009] At least one wheel support wall has a generator unit and a circuit board installed on its inner and outer sides, respectively. The side of the wheel support wall adjacent to the roller is the inner side, and the side of the wheel support wall away from the roller is the outer side. The circuit board is installed inside the outer casing, which is screwed onto the outer side of the wheel support wall. The generator unit consists of a coil, an exciter, and an inner casing. The coil is a ring structure, and the exciter is a sphere made of permanent magnet. The bottom wall of the inner casing has a coaxial inner cylinder and an outer cylinder. The end of the outer cylinder has a flange. The outer cylinder is longer than the inner cylinder. The inner cylinder and the outer cylinder form a coil groove, which is an annular groove. The coil is placed in the coil groove, and the exciter is placed in the inner cylinder cavity. The flange of the inner casing is screwed onto the wheel support wall. A gasket is placed between the inner cylinder and the wheel support wall, separating the exciter and coil from the wheel support wall. The axis of the coil is parallel to the axis of the wheel axle and the roller.

[0010] In this invention, the bushing, axle, wheel bracket, outer shell, and inner shell are all made of non-ferromagnetic materials.

[0011] After the roller skates are assembled, the distance from the geometric center of the exciter and the magnet to the axis of the wheel axle is equal. The minimum distance between two adjacent exciters on the same axial section of the roller in the circumferential direction must satisfy the following: when the distance between one exciter and the adjacent magnet is the closest and the force is the greatest, there is no interaction force between the other exciter and the magnet, that is, the force between the two is zero.

[0012] When people wear roller skates, the rollers rotate continuously relative to the axle and wheel support. The exciter and the magnet alternately approach and separate, generating alternating forces between them. Because the magnet is a non-fixed, freely rotating sphere, an attraction is generated between the exciter and the magnet as they gradually approach and move away. As the exciter moves away from the magnet, it applies a rotational torque to the magnet, causing it to rotate rapidly and its two magnetic poles and magnetic field direction to change rapidly. The coil generates electricity by cutting the magnetic lines of force.

[0013] In this invention, the electrical energy generated by the power generation unit is transmitted to the circuit board via wires. When multiple power generation units generate electricity, they each use independent wires and rectifier bridges to output to the circuit board. The circuit board is equipped with an energy management and storage unit, a voice control unit, and an information transmission unit.

[0014] In this invention, to obtain better power generation capability, the parameter relationship between the coil and the exciter is: δ=T / D=0.6±0.4, η=V / D=2.25±0.75, β=U / D=1.3±0.7, where D is the diameter of the exciter, and T, V and U are the wall thickness, outer diameter and height of the coil, respectively.

[0015] Unlike existing electromagnetic power generation that relies on changes in magnetic field strength caused by the movement of an exciter, the power generation unit in this invention mainly generates electricity by changing the magnetic field strength through the rotation of the exciter. The exciter's main function is to drive the exciter to rotate rapidly. In this invention, the magnetic field direction when the magnetic field strength is at its maximum during the rotation of the exciter is parallel to the coil axis. The change in magnetic field strength caused by the change in the direction of the magnetic field inside the coil is large, and the exciter can generate multiple rotations and the coil can cut magnetic lines of force multiple times when excited once. Therefore, the power generation capacity is strong, the output voltage is high, and the amount of electricity is large.

[0016] Advantages and features: It has a self-generating function, which facilitates the use of lights and sounds for gliding in urban areas and for positioning and tracking of gliding activities in the wild. It can also be used as a power source for portable products. The power generation unit is non-contact toggle-activated, with a simple structure and excitation method, high mechanical reliability, and can generate electricity multiple times with a single excitation. The magnetic field gradient changes rapidly, resulting in a large amount of electricity generated and a high output voltage. Attached Figure Description

[0025] This invention proposes a roller skating shoe, which mainly includes a shoe body D, a wheel bracket B, a roller A, and a wheel axle C. The shoe body D is mounted on the horizontal plate b1 of the wheel bracket, the roller A is fitted on the wheel axle C, the wheel axle C is mounted on the vertical wall b2 of the wheel bracket, and a circuit board p and a power generation unit E are mounted on the vertical wall b2 of the wheel bracket. The power generation unit E is composed of a coil x, an exciter y, and an inner shell z.

[0026] Roller A consists of a wheel body a1 and a bushing a2. The wheel body a1 is fitted onto the outer edge of the bushing a2. The wheel body a1 is fitted onto the bushing a2 by injection molding. The convex ring a11 on the inner edge of the wheel body a1 is embedded in the annular groove on the outer edge of the bushing a2. An actuator w is embedded in the wheel body a1 of roller A. The wheel body a1 of roller A contains one long set or two short sets of actuators w. The two sets of actuators w are evenly distributed on two different axial sections and are close to the left and right sides of the wheel body a1, respectively. The actuator w is a cube, cylinder, or sphere. The actuator w is made of ferromagnetic material, such as iron, cobalt, nickel, or a permanent magnet. When the actuator w is a permanent magnet, its magnetic poles are arranged along the axial direction of the wheel body a1 or along the circumference of the wheel body a1. The material of the wheel body a1 is rubber or plastic, and the bushing a2 is made of non-ferromagnetic material, such as metal or high-strength plastic.

[0027] When the actuator w is a permanent magnet and its magnetic poles are all arranged along the axial direction of the wheel body a1, the magnetic poles of two axially adjacent actuators w in the two sets of actuators w are arranged in the same direction, that is, the opposite magnetic poles of the two actuators w are opposite to each other. The magnetic poles of two circumferentially adjacent actuators w in the same set of actuators w are arranged in opposite directions, that is, the opposite magnetic poles of the two actuators w are located in the same axial section of the wheel body a1.

[0028] When the actuator w is a permanent magnet and its magnetic poles are all arranged along the circumferential direction of the wheel body a1, the magnetic poles of two axially adjacent actuators w in the two sets of actuators w are arranged in opposite directions, that is, the opposite magnetic poles of the two actuators w are opposite to each other along the axial direction of the wheel body a1. The magnetic poles of two circumferentially adjacent actuators w in the same set of actuators w are arranged in the same direction, that is, the opposite magnetic poles of the two actuators w are close to each other.

[0029] The axle C is composed of an axle body c1 and studs c2 at both ends of the axle body c1. The axle body c1 and studs c2 are an integral structure. The material of the axle C is a non-ferromagnetic material.

[0030] Roller A is mounted on the shaft body c1 of axle C through bushing hole a3 and is axially positioned by two inner nuts f. Roller A can rotate freely around shaft body c1. The two inner nuts f are mounted on studs c2 at both ends of axle C and abut against both sides of shaft body c1 respectively. Roller A is located between the two inner nuts f and can rotate relative to the inner nuts f. Axle C is mounted on wheel bracket wall b2 through two inner nuts f and two outer nuts g. The studs c2 at both ends of axle C are located in the slots of the two wheel bracket walls b2 respectively. The inner nuts f and outer nuts g press the axle onto the wheel bracket wall b2.

[0031] At least one wheel support wall b2 has a power generation unit E and a circuit board p installed on its inner and outer sides, respectively. The side of the wheel support wall b2 adjacent to the roller A is the inner side, and the side of the wheel support wall b2 away from the roller A is the outer side. The circuit board p is installed inside the outer casing d, which is screwed onto the outer side of the wheel support wall b2. The power generation unit E consists of a coil x, an exciter y, and an inner casing z. The coil x is a ring structure, and the exciter y is a sphere made of permanent magnet. The bottom wall z1 of the inner casing z has a coaxial inner cylinder z3 and an outer cylinder z2. The end of the inner shell is provided with a flange z6. The outer cylinder z2 is longer than the inner cylinder z3. The inner cylinder z3 and the outer cylinder z2 form a coil groove z5, which is an annular groove. The coil x is placed in the coil groove z5, and the exciter y is placed in the inner cylinder cavity z4. The flange z6 of the inner shell z is installed on the wheel bracket wall b2 by screws. A gasket h is provided between the inner cylinder z3 and the wheel bracket wall b2. The gasket h separates the exciter y and the coil x from the wheel bracket wall b2. The axis of the coil x is parallel to the axis of the wheel axle C and the roller A. The wheel bracket B, the outer shell d, and the inner shell z are all made of non-ferromagnetic materials.

[0032] After the roller skates are assembled, the distances from the geometric centers of the exciter w and the magnet y to the axis of the wheel axle C are equal. The minimum distance between two exciters w that are adjacent in the circumferential direction on the same axial section of the roller A must satisfy the following: when one exciter w is closest to the adjacent magnet y and the force is the greatest, there is no interaction force between the other exciter w and the magnet y, that is, the force between the two is zero.

[0033] When people wear roller skates and skate, the roller A rotates continuously relative to the axle C and the wheel support B. The exciter w and the exciter y alternately approach and separate, generating alternating forces between them. Since the exciter y is a non-fixed, freely rotating sphere, an attraction is generated between the exciter w and the exciter y as they gradually approach and gradually move away. As the exciter w moves away from the exciter y, it applies a rotational torque to the exciter y, causing the exciter y to rotate rapidly and its two magnetic poles and magnetic field direction to change rapidly. The coil generates electricity by cutting the magnetic lines of force.

[0034] In this invention, the electrical energy generated by the power generation unit E is transmitted to the circuit board p via wires. When multiple power generation units E generate electricity, they each use independent wires and rectifier bridges to output to the circuit board p. The circuit board p is equipped with an energy management and storage unit, a voice control unit, and an information transmission unit.

[0035] In this invention, to obtain better power generation capability, the parameter relationship between coil x and exciter y is: δ=T / D=0.6±0.4, η=V / D=2.25±0.75, β=U / D=1.3±0.7, where D is the diameter of exciter y, and T, V and U are the wall thickness, outer diameter and height of coil x, respectively.

[0036] Unlike existing electromagnetic power generation that relies on changes in magnetic field strength caused by the movement of an exciter, in this invention, the power generation unit E mainly generates electricity by changing the magnetic field strength through the rotation of the exciter y. The exciter w mainly drives the exciter to rotate rapidly. In this invention, the magnetic field direction when the magnetic field strength is at its maximum during the rotation of the exciter y is parallel to the coil axis. The change in magnetic field strength caused by the change in the direction of the magnetic field in the coil x is large, and the exciter y can generate multiple rotations when excited once, and the coil x cuts the magnetic lines of force multiple times. Therefore, the power generation capacity is strong, the output voltage is high, and the amount of electricity is large.
