[0001] The present invention relates to the technical field of kinetic energy conversion equipment, and in particular to a kinetic energy conversion type Ampere force coupler. Background Art

[0002] Couplers are often used during the use of fuel vehicles or other large-scale mechanical equipment with more complex working conditions. Currently, the commonly used couplers are mainly hydraulic couplers and magnetic couplers. The hydraulic coupler occupies a large space between the power machine and the working machine, and uses oil as the medium for transmitting torque. The seal is easy to break and oil leakage occurs. The magnetic coupler uses the Ampere force generated by the mutual movement between the permanent magnet and the conductor to realize the torque transmission between the power machine and the working machine.

[0003] During the use of fuel vehicles or other large-scale mechanical equipment with more complex working conditions, the power of the rear-end load will change with the changes in the working conditions, and the power fluctuations of the load are relatively large. Most of the time, it cannot reach full load operation, resulting in the engine power not being fully utilized, causing waste; and the other electrical equipment on the vehicle, such as the air conditioner and lighting lamps on the vehicle, also need to be equipped with separate charging equipment to power them, making the structure of the entire vehicle more complicated and the manufacturing cost higher. Summary of the invention

[0004] The purpose of the present invention is to provide a kinetic energy conversion Ampere force coupler that can output power and current simultaneously to avoid the situation where the load cannot run at full load under complex working conditions, resulting in the engine power not being fully utilized and causing waste.

[0005] The present invention comprises an input shaft, the input shaft is connected to a planetary gear speed increaser, the output end of the planetary gear speed increaser is connected to an intermediate shaft, an outer rotor assembly is installed on the intermediate shaft, a plurality of permanent magnets are installed around the inner side of the outer rotor assembly; an inner rotor assembly is coupled to the inner side of the outer rotor assembly, a plurality of induction coils are installed around the inner rotor assembly, the inner rotor assembly is connected to an output shaft, and the output shaft is connected to a load; a power receiving slip ring is also installed on the output shaft, a carbon brush is installed on the outer side of the power receiving slip ring, and the carbon brush is electrically connected to a power storage device.

[0006] Preferably, the planetary gear speed increaser comprises an input gear, the outer periphery of which is meshed with a planetary gear, a gear shaft is installed inside the planetary gear, a driven gear is also installed on the gear shaft, the driven gear is meshed with an output gear outside, and the output gear is connected to an intermediate shaft.

[0007] Preferably, the layout of the permanent magnets in the outer rotor assembly adopts a radial layout.

The permanent magnet one is evenly arranged along the circumference, the magnetic pole direction of the permanent magnet one is along the diameter direction, and the magnetic pole directions of adjacent permanent magnets one are opposite, that is, the N pole of one permanent magnet one points to the center of the circle, and the S pole of an adjacent permanent magnet one points to the center of the circle.

[0008] Preferably, the layout of the permanent magnets in the outer rotor assembly adopts a circumferential layout. The outer rotor assembly includes a flange, permanent magnet 2, a yoke, an upper magnetic isolation plate and a lower magnetic isolation plate. The permanent magnet 2 is evenly arranged along the circumference, the magnetic pole direction of the permanent magnet 2 is along the tangent direction of the circumference, and the magnetic pole directions of adjacent permanent magnets 2 are opposite; the permanent magnet positioning block is made of non-magnetic material; the flange is made of non-magnetic material.

[0010] Preferably, a control switch capable of controlling the connection or disconnection of the current loop between the carbon brush and the power storage device is provided between the carbon brush and the power storage device.

[0011] In summary, the present invention has the following beneficial effects:

[0012] 1. The input shaft rotates under the action of external power, and after being accelerated by the planetary gear speed increaser, the power is transmitted to the intermediate shaft, which drives the outer rotor assembly to rotate at high speed through the intermediate shaft, and forms a rotating magnetic field synchronized with the intermediate shaft; due to the rotation of the permanent magnet outer rotor assembly, a rotating magnetic field is generated in the gap, and an induced current is generated in the guide bar in the inner rotor assembly.

The electricity charged by the energy storage device can be used in other electrical equipment. Power transmission is achieved while charging the energy storage device, thereby realizing diversified transmission and conversion of energy. The structure is simple and the transmission efficiency is high.

[0014] 2. A control switch is provided between the carbon brush and the energy storage device.

[0026] The planetary gear speed increaser 2 includes an input gear 201, the outer periphery of which is meshed with a planetary gear 202, a gear shaft 203 is installed inside the planetary gear 202, a driven gear 204 is also installed on the gear shaft 203, the driven gear 204 is meshed with an output gear 205 on the outside, and the output gear 205 is connected to the intermediate shaft 3; the external power is input from the input shaft 1, and after being accelerated by the planetary gear speed increaser 2, the power is transmitted to the intermediate shaft 3, and the outer rotor assembly 4 is driven to rotate at a high speed through the intermediate shaft 3.

[0027] This technology includes conventional excitation generators. For the convenience of explaining its working principle, a permanent magnet generator is taken as an example. A plurality of permanent magnets are installed around the outer rotor assembly 4. The permanent magnets in the outer rotor assembly 4 are made of rare earth permanent magnet materials, and the number of magnetic poles thereof should satisfy the following relationship: f c =2pn s / N c ; where f c is the torque fluctuation factor; p is the number of permanent magnet pole pairs; n s N is the number of cage rotor bars; c For p and n s The least common multiple of c The selection criterion of is the minimum value that satisfies the above formula.

[0028] In one embodiment, if Figure 6 As shown, the layout of the permanent magnets in the outer rotor assembly 4 adopts a radial layout. The outer rotor assembly 4 includes a flange-shaped yoke 9, a pole shoe 10, a permanent magnet positioning block 11 and a permanent magnet 12. The permanent magnet 12 is evenly arranged along the circumference, and the magnetic pole direction of the permanent magnet 12 is along the diameter direction. The magnetic pole directions of adjacent permanent magnets 12 are opposite, that is, the N pole of one permanent magnet 12 points to the center of the circle, and the S pole of the adjacent permanent magnet 12 points to the center of the circle.

[0029] In another embodiment, Figure 7As shown, the layout of the permanent magnets in the outer rotor assembly 4 adopts a circumferential layout. The outer rotor assembly 4 includes a flange 13, a permanent magnet 14, a yoke 9, an upper magnetic isolation plate 15 and a lower magnetic isolation plate 16. The permanent magnet 14 is evenly arranged along the circumference, and the magnetic pole direction of the permanent magnet 14 is along the tangent direction of the circumference, and the magnetic pole directions of adjacent permanent magnets 14 are opposite; the permanent magnet positioning block 11 is made of non-magnetic material; the flange 13 is made of non-magnetic material.

[0030] The working principle of the present invention is as follows: the input shaft 1 rotates under the action of external power, and after being accelerated by the planetary gear speed increaser 2, the power is transmitted to the intermediate shaft 3, and the outer rotor assembly 4 is driven to rotate at a high speed through the intermediate shaft 3, and a rotating magnetic field synchronized with the intermediate shaft 3 is formed; due to the rotation of the permanent magnet outer rotor assembly 4, a rotating magnetic field is generated in the gap, and an induced current is generated in the conductive bar in the inner rotor assembly 5. The current is acted upon by the Ampere force in the magnetic field, so that the inner rotor assembly 5 rotates with the permanent magnet outer rotor assembly 4 at a certain slip rate, thereby realizing the transmission of the torque of the permanent magnet outer rotor assembly 4 to the inner rotor assembly 5, and the output shaft 6 is connected to the inner rotor assembly 5 by a key connection or a pressing method, and the torque is transmitted to the load.

[0031] At the same time, a power receiving slip ring 7 is also installed on the output shaft 6, and a carbon brush 8 is installed on the outer side of the power receiving slip ring 7. The carbon brush 8 is electrically connected to the power storage device. The current generated by the inner rotor assembly 5 cutting the magnetic flux lines is conducted through the power slip ring 7 and the carbon brush 8 to charge the external power storage device. The power transmission is realized while charging the power storage device, thereby realizing the diversified transmission and conversion of energy, with a simple structure, high transmission efficiency, and improved energy utilization rate.

[0032] The coupler uses the torque (Ampere force) principle generated by a conventional generator during the power generation process. Through mechanical design, two freely rotatable inner and outer rotors are optimally combined together, one of which is connected to the power source, and the other outputs power and is connected to the load. The speed difference between the two rotors is used to cut the magnetic flux lines, thereby generating current. The charged conductor can generate Ampere force in the magnetic field, and this force couples the input kinetic energy to the output rotor to transmit power. Among them, the current output by the induction coil directly determines the size of the coupling force. The size of the current is proportional to the speed of the power source input and the torque of the power output. When the current output is 0, the coupling force is also 0. In addition, by adjusting the input speed and output current, soft starting can be effectively achieved, and adjusting the size of the current output can change the size of the output speed and torque. By adjusting the input speed and output current, the output speed and torque can be flexibly controlled, thereby achieving efficient energy conversion and power transmission. This device has broad application prospects in occasions where electricity and power transmission are required at the same time.

[0033] Among them, a control switch is arranged between the carbon brush 8 and the energy storage device. By operating the opening and closing of the control switch, the connection or disconnection of the current circuit between the inner rotor assembly 5 and the energy storage device can be realized. When the control switch is closed, a current circuit is formed between the inner rotor assembly 5 and the energy storage device, and current flows through the inner rotor assembly 5, and the inner rotor assembly 5 charges the energy storage device; and the inner rotor assembly 5 rotates under the action of the Ampere force, driving the output shaft 6 to rotate, thereby transmitting the torque to the load; when the control switch is disconnected, the current circuit between the inner rotor assembly 5 and the energy storage device is disconnected, the outer rotor assembly 4 idles, and the inner rotor assembly 5 no longer rotates, thereby failing to drive the load to operate; the coupling or disconnection between the outer rotor assembly 4 and the inner rotor assembly 5 is controlled by the control switch to realize the operation or stop of the rear end load device, thereby avoiding the repeated starting or stopping of the front end power input device, which results in large energy loss, and too frequent starting and stopping will also affect the service life of the equipment.

Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
