Description

An electromagnetic coupling energy transmission device Technical Field

[0001] The present invention relates to an energy transmission device using electromagnetic induction for electric field coupling communication, and in particular sets specifications for the dimensions of an electric field sheet and a magnetic module used for electric field coupling communication, as well as the positional relationship between the electric field sheet, coil, and magnetic module, as well as the necessary characteristics for application in small personal transportation vehicles. Background Art

[0002] Cases of spontaneous combustion of small personal vehicles such as electric motorcycles and electric bicycles due to leakage, sparking and short circuits caused by rain occur every day, resulting in serious safety accidents and major property losses. Statistics show that the main reason is that the metal electrodes of the existing metal contact charging method are generally rusted due to exposure to the outdoor environment. There are only two solutions: the first is to use large personal vehicles such as electric vehicles, which adopt a charging gun and charging gun sleeve mechanical structure and a power supply algorithm technology with output voltage or current soft start. However, the cost will be close to 1 / 4 of the cost of a small personal vehicle, which is obviously inappropriate; the second is to use non-electrical contact charging technology, that is, to realize electromagnetic coupling energy transmission technology through coils to completely eliminate the possibility of leakage and sparks.

[0003] Existing electromagnetic coupling energy transmission technologies include the QI technology commonly used on mobile phones and the magnetic resonance technology invented by a team at the Massachusetts Institute of Technology. However, QI technology has technical defects such as low system conversion efficiency when the output power exceeds 15W, significant fluctuations in the output voltage or current of the electromagnetic coupling energy input device, and slow control closed-loop speed. Magnetic resonance technology has technical defects such as high material cost and slow control closed-loop speed. After comprehensive analysis, only the CN 2022106826024 technology applied by the inventor in 2022 has the advantages of the highest year-on-year efficiency, extremely fast control closed-loop that can achieve real-time feedback and response, the lowest year-on-year cost, and stable output voltage or current of the electromagnetic coupling energy input device. Therefore, it is most suitable for designing an electromagnetic coupling energy transmission device kit with an output power range of 100~1000W, which includes an energy output device and an energy input device using electromagnetic coupling energy transmission technology, for use in the field of personal small vehicles.

[0004] In real-world parking lots equipped with electromagnetic coupling energy transfer (ECET) charging, devices with a rated output power of 1000W are generally considered. However, the rated input power of small personal vehicles varies from 100 to 1000W. Alternatively, a user might install an EET device with a rated output power of 500W at home to charge a family member's electric scooter, 200W electric bicycle, or 800W electric motorcycle. Therefore, compatibility between EET devices with different power ratings must be considered.

[0005] Because electromagnetic coupling energy transmission devices of different power levels use coil modules of different sizes to reduce size and cost, for example, 100-200W devices generally use coil modules with a diameter of 40mm, 300-500W devices generally use coil modules with a diameter of 60mm, and 500-1000W devices generally use coil modules with a diameter of 80mm. During electromagnetic coupling energy transmission, the outer winding of the coil module experiences a high varying voltage AVc, generating an alternating electric field in the surrounding space. The PFM-type alternating voltage AVt is typically transmitted across the conductors used for electric field coupling communication in the CN 2022106826024 technology. Therefore, when the conductors used for electric field coupling communication in the CN 2022106826024 technology are interfered with by the AVc alternating electric field, the waveform of the AVt of the electric field coupling communication can be affected or even overwhelmed, causing signal loss and subsequent inability to operate. Therefore, it is necessary to set the spatial position between the electromagnetic coupling energy transmission coil and the conductor used to adjust the electromagnetic coupling energy transmission power to ensure that different models of products can be compatible with each other and charge using electromagnetic coupling technology.

[0006] Considering the aesthetics of small personal vehicles and national laws and regulations, the optimal temporary fixation method for the energy output device and the energy input device is through magnetic field adsorption. Therefore, a magnetic module needs to be designed to achieve temporary fixation through magnetic field adsorption. However, because at least one side of the magnetic module must use a magnet or electromagnet, and the magnet or electromagnet needs to generate a sufficiently strong magnetic field adsorption capability, its surface fixed magnetic induction intensity is very strong and exceeds the saturation magnetic induction intensity of the soft magnetic material of the coil module. Therefore, if the magnet or electromagnet is very close to the soft magnetic material, the soft magnetic material near the magnet or electromagnet will become magnetically saturated or close to magnetic saturation. When the alternating magnetic field in the electromagnetic coupling energy transmission passes through this area, the soft magnetic material will be significantly heated, which not only affects the efficiency of energy transmission but also poses a serious safety hazard. Therefore, it is necessary to design and standardize the position and size of the magnetic module, and the shape and size of the soft magnetic material of the coil module, while achieving compatibility and high-efficiency electromagnetic coupling energy transmission.

[0007] Considering the wide variety of small personal vehicle (PMV) product forms, with surfaces often curved for aesthetics, and low-cost coil modules that are easily mass-produced, typically flat, integrating the coil module into the PMV's exterior is challenging, requiring a custom design for each product. On the other hand, PMVs typically feature rearview mirrors for enhanced safety, and the backs of rearview mirrors are typically flat. Therefore, an electromagnetic coupling energy input device could be integrated with the rearview mirror. The electromagnetic coupling energy input device could be installed outside the PMV's main body and connected to the PMV's battery module via a cable. Therefore, the internal structure of the electromagnetic coupling energy input rearview mirror needed to be designed to meet functional requirements. Technical issues

[0008] Cases of electric motorcycles, electric bicycles and other small personal transportation vehicles spontaneously catching fire due to leakage, sparking and short circuits during rain occur every day, resulting in serious safety accidents and major property losses. Statistics show that the main reason is that the metal electrodes of the existing metal contact charging method are generally corroded due to exposure to the outdoor environment. Technical Solutions

[0009] There are only two solutions: the first is to use a large personal vehicle, such as an electric car, which uses a charging gun and a charging gun sleeve-type mechanical structure and a power supply algorithm technology with output voltage or current soft start. However, the cost will be close to 1 / 4 of the cost of a small personal vehicle, which is obviously inappropriate; the second is to use non-electrical contact charging technology, that is, to realize electromagnetic coupling energy transmission technology through coils, completely eliminating the possibility of leakage and sparks.

[0010] Existing electromagnetic coupling energy transmission technologies include the QI technology commonly used on mobile phones and the magnetic resonance technology invented by a team at the Massachusetts Institute of Technology. However, QI technology has technical defects such as low system conversion efficiency when the output power exceeds 15W, significant fluctuations in the output voltage or current of the electromagnetic coupling energy input device, and slow control closed-loop speed. Magnetic resonance technology has technical defects such as high material cost and slow control closed-loop speed. After comprehensive analysis, only the CN 2022106826024 technology applied by the inventor in 2022 has the advantages of the highest year-on-year efficiency, extremely fast control closed-loop that can achieve real-time feedback and response, the lowest year-on-year cost, and stable output voltage or current of the electromagnetic coupling energy input device. Therefore, it is most suitable for designing an electromagnetic coupling energy transmission device kit with an output power range of 100~1000W, which includes an energy output device and an energy input device using electromagnetic coupling energy transmission technology, for use in the field of personal small vehicles.

[0011] The present invention discloses an electromagnetic coupling energy transmission device, which is characterized in that it has an electric energy conversion module, a coil module, a communication port and a shell; the electric energy conversion module has an AC power transmission port and a communication sub-module, which can convert AC power into external electric energy, and the communication sub-module has a signal transmission end and is used to transmit first information for controlling the AC power parameters; it has a coil and soft magnetic material for electromagnetic coupling energy transmission, and the coil module is electrically connected to the AC power transmission end; the communication port has an electric field sheet module, which is composed of a conductor and is used for electric field coupling communication, and the communication port is electrically connected to the signal transmission end; the electric field sheet module has a first plane where the surface is located close to the coil module and facing the electromagnetic coupling energy transmission direction.

[0012] To ensure optimal compatibility and mitigate interference with the electric field sheet during operation, the minimum distance (a) from the center of the coil module to the electric field sheet is 30-50 mm, and the length of the line connecting the center of the coil module to the center of the electric field sheet is 40-60 mm. This ensures that coil module sizes ranging from 40 mm in diameter to 80 mm in diameter will not overlap with the projection of the electric field sheet module onto the plane containing the sheet, nor will their projection exceed half the area of ​​the sheet.

[0013] According to the capacitance calculation formula, when the overlap area between the electric field sheet module and the coil module is small or almost non-existent, the capacitance formed between the electric field sheet module and the coil module is very small, making electric field coupling signal transmission relatively difficult or even extremely difficult. Therefore, when the electromagnetic coupling energy transmission device disclosed in the present invention is operating and an AC voltage is applied to the coil module, the alternating electric field in the area near the electric field sheet module will have relatively little interference with the electric field sheet module, and thus will not seriously interfere with the first information. This allows for compatibility between different models of electromagnetic coupling energy transmission devices disclosed in the present invention, thereby achieving high-efficiency, high-accuracy, and high-real-time electromagnetic coupling energy transmission.

[0014] The electric field sheet module has at least two forms. The first is that the electric field sheet module is a single continuous conductor, the signal transmission end of the communication sub-module is a single signal input and output interface, and the signal transmission end of the communication sub-module transmits a PFM-type square wave signal superimposed with a DC voltage bias; the second is that the electric field sheet module has two independent continuous conductors, and the electrical characteristics of the first information are two related PFM-type square wave signals superimposed with a DC voltage bias, and the related connection includes one of level difference, phase offset, and duty cycle difference; the two independent continuous conductors are the first electric field sheet and the second electric field sheet, respectively, and the shortest distance (d) between the first electric field sheet and the second electric field sheet is 10-20mm.

[0015] The first form can effectively cope with interference caused by harsh environments such as acid rain, salt spray, and seawater, but is more susceptible to interference from the coil module; the second form can effectively overcome the interference of the coil module, but is more susceptible to interference from objects with certain conductive capabilities such as condensation, acid rain, salt spray, and seawater.

[0016] The device disclosed in the present invention may also have a magnetic attraction module, the function of which is that when the device disclosed in the present invention needs to be temporarily fixed with other paired devices, the magnetic attraction module has the function of realizing magnetic field adsorption with the magnetic attraction components of the other paired devices under the action of the magnetic field. Therefore, the surface of the device disclosed in the present invention is very beautiful; and the center points of the coil module, the electric field sheet module and the magnetic attraction module are almost on the same straight line, and the magnetic attraction module is close to the first plane.

[0017] In order to avoid obvious misalignment between the opposing coil modules or the opposing electric field sheet modules when temporary fixation is achieved through magnetic field adsorption, so that high-efficiency electromagnetic coupling energy transmission or electric field coupling signal transmission cannot be performed, the magnetic attraction module includes at least a first magnetic attraction component and a second magnetic attraction component, and the first magnetic attraction component is closer to one side of the coil module, and the distance (f) from the center of the first magnetic attraction component to the center of the second magnetic attraction component is 91-101mm; and the distance (g) from the center of the first magnetic attraction component to the center of the coil module is 23-29mm; and the length of any one of the magnetic attractions components in the direction of the center line connecting the first magnetic attraction component and the second magnetic attraction component is 4~12mm.

[0018] Because the first magnetic attraction component may be a permanent magnet or an electromagnet, or it may be a ferromagnetic material magnetized by the first magnetic attraction component of other paired devices, and in order to avoid severe magnetization of the soft magnetic material, after referring to the closed magnetic flux three-dimensional structure of common permanent magnets, in the device disclosed by the present invention, when the coil diameter of the coil module is greater than 45 mm, the soft magnetic material of the coil module needs to be specifically designed in the area close to the first magnetic attraction component, so that the shortest distance D1 from the soft magnetic material to the first magnetic attraction component is greater than 1 / 5 of the shortest distance D2 from the center point of the first magnetic attraction component to the soft magnetic material.

[0019] In order to prevent users from getting confused during use, when the device disclosed in the present invention is mainly used for energy output, the central area of ​​the side of the first magnetic component facing the electromagnetic coupling energy transmission direction of the coil module is the S pole, and the central area of ​​the side of the second magnetic component facing the electromagnetic coupling energy transmission direction of the coil module is the N pole; and when the device disclosed in the present invention is mainly used for energy input, the central area of ​​the side of the first magnetic component facing the electromagnetic coupling energy transmission direction of the coil module is the N pole, and the central area of ​​the side of the second magnetic component facing the electromagnetic coupling energy transmission direction of the coil module is the S pole.

[0020] The device disclosed in the present invention is primarily used to charge electric vehicles via electromagnetic coupling energy transmission. Therefore, when the electromagnetic coupling energy transmission device disclosed in the present invention serves as an electromagnetic coupling energy input device, the device is in the form of a rearview mirror. The rearview mirror has a reflective lens. Once the electromagnetic coupling energy transmission device described in the present invention is installed and secured, the reflection is generally directed toward the user. Because the mirror utilizes a process such as aluminum plating to create a reflective layer, a metal layer approximately 0.1 mm thick exists, making it difficult for the alternating magnetic field to penetrate, while the alternating electric field may be attenuated or interfered with. Therefore, the coil module and the electric field sheet module are disposed on the back of the reflective lens. The electromagnetic coupling energy transmission direction of the coil module is generally directed away from the reflective lens, while the electric field coupling information transmission direction of the electric field sheet module is generally directed away from the reflective lens. As a rearview mirror, the reflective lens generally utilizes a convex mirror structure.

[0021] Furthermore, the reflector also has a camera module, and the camera transmits the captured image information to a matching image receiving module.

[0022] Furthermore, the image receiving module has a recording submodule, and the image receiving module stores the image information output by the camera module after obtaining it.

[0023] Taking into account the cost and volume as well as the requirements for image clarity, the camera module adopts a fisheye lens with a field of view exceeding 180°, and the lens axis of the camera module is substantially parallel to the surface of the mirror.

[0024] Generally speaking, the electric vehicles are electric bicycles, electric motorcycles, electric small tractors, electric wheelchairs, and the like. Beneficial effects

[0025] This invention utilizes contactless charging technology, achieving electromagnetic coupling energy transmission through coils, completely eliminating the possibility of leakage and sparking. It offers the highest efficiency, extremely fast closed-loop control for real-time feedback and response, the lowest cost, and a stable output voltage or current from the electromagnetic coupling energy input device.

[0035] Figure 1 shows an embodiment of the present invention comprising at least a coil module 1, an electric field sheet module 2, a power conversion module 3, and a housing 4, wherein the electric field sheet module 2 is a continuous conductor. The coil module 1 is electrically connected to the AC power transmission terminal of the power conversion module 3 and transmits a first AC current. The electric field sheet module 2 is electrically connected to the signal transmission terminal of the communication submodule 31 of the power conversion module 3 and transmits a first information signal. The electrical signal characteristic of the first information is a PFM-like square wave signal superimposed with a DC voltage bias. The housing 4 has a first region for electromagnetically coupled energy transmission and electric field coupled communication transmission. The coil module 1 and the electric field sheet module 2 are located in close proximity in the first region of the housing 4. Furthermore, the shortest distance (a) from the center of the coil module 1 to the electric field sheet module 2 is 30-50 mm, and the length (b) of the line connecting the center of the coil module to the center of the electric field sheet module is 40-60 mm.

[0036] The difference between Figure 2 and Figure 1 is that the electric field sheet module 2 includes a first electric field sheet 21 and a second electric field sheet 22, wherein the positions of the electric field sheets 21 and 22 can be interchanged, and the first information is transmitted simultaneously between the communication sub-module 31 and the first electric field sheet 21, and between the communication sub-module 31 and the second electric field sheet 22. In the embodiment of Figure 2, the electrical signal characteristics of the first information transmitted by the communication sub-module 31 and the first electric field sheet 21, and by the communication sub-module 31 and the second electric field sheet 22 are respectively a PFM-type first square wave signal and a second square wave signal superimposed with an independent DC voltage bias.

[0037] In all embodiments, if the communication submodule 31 in the embodiments of the present invention serves as the first information receiver and receives the first information, it will control the power conversion module 3 to adjust the parameters of the first alternating current according to the first information.

[0038] Figures 3 and 4 show a set of matching electromagnetic coupling energy transmission devices, where Figure 3 shows an electromagnetic coupling energy output device and Figure 4 shows an electromagnetic coupling energy input device, and the direction of Figures 3 and 4 toward the reader is the direction of electromagnetic coupling energy transmission. In Figures 3 and 4, compared to Figure 1, a magnetic module 5 is added. The center points of the magnetic module 5, coil module 1, and electric field sheet module 2 are almost on the same straight line. The magnetic module 5 includes a first magnetic component 51 and a second magnetic component 52. The spatial distance (f) from the center of the first magnetic component to the center of the second magnetic component is 91-101 mm, and the distance (g) from the center of the first magnetic component to the center of the coil module is 23-29 mm.

[0039] In Figure 3 , the center area of ​​the side of the first magnetic component 51 facing the direction of electromagnetic coupling energy transmission of the coil module 1 is the S pole, and the center area of ​​the side of the second magnetic component 52 facing the direction of electromagnetic coupling energy transmission of the coil module 1 is the N pole. In Figure 4 , the center area of ​​the side of the first magnetic component 51 facing the direction of electromagnetic coupling energy transmission of the coil module 1 is the N pole, and the center area of ​​the side of the second magnetic component 52 facing the direction of electromagnetic coupling energy transmission of the coil module 1 is the S pole.

[0040] In actual use, when the respective first areas of the electromagnetic coupling energy transmission devices shown in Figures 3 and 4 are close to each other, the respective magnet modules 5 of the electromagnetic coupling energy transmission devices shown in Figures 3 and 4 are attracted to each other by the magnetic field, thereby achieving alignment and adsorption, and then achieving the respective coil modules 1 facing each other to achieve efficient electromagnetic coupling energy transmission, and the respective electric field sheet modules 2 facing each other to achieve efficient electric field coupling first signal transmission.

[0041] When the coil 11 of the coil module 1 is large in size, the matching soft magnetic material 12 will be closer to the first magnetic component 51. In order to avoid severe magnetization of the first magnetic component 51, an arc structure away from the first magnetic component 51 is specially designed on the soft magnetic material 12 to ensure that the shortest distance D1 from the soft magnetic material 12 to the first magnetic component 51 is greater than 1 / 5 of the shortest distance D2 from the center point of the first magnetic component to the soft magnetic material.

[0042] Figures 6 and 7 show exploded views of the present invention as an electromagnetically coupled energy input device in the form of a rearview mirror. Compared to Figure 4, a reflective lens 6 and a camera module 7 are added. When the embodiments of Figures 5 and 6 are mounted on the handlebars of a small personal vehicle, the reflective lens 6 provides a rearview mirror function facing the rear of the small personal vehicle, while the camera module 7 can capture road surface images during driving and provide them to a recording module for storage or to a computing module for recognition and judgment.
