Description of the Invention: [Technical Field] The present invention relates to an energy transmission system and an energy transmission end assembly, and more particularly to an energy transmission system and an energy transmission end device having a small volume. [Prior Art] With the rapid development of technology, human beings have developed a wide range of electronic products to meet their needs. However, many electronic products provide power supplies such as transformers by means of wired transmission energy transmission systems, such as transformers. In order to allow users to use electronic products without restrictions, the wireless transmission energy transmission system has been continuously developed, and how to improve the transmission efficiency of the energy transmission system has become one of the goals pursued. In one example, the energy transfer device of the energy transfer system includes a resonator, a feed coil, a resonator, and the like. When the energy transfer device of the energy transfer system transmits the energy signal, the energy signal is transmitted through the resonator to resonate to a desired frequency, and the energy signal is coupled to the common resonator by feeding the coil. The resonator then wirelessly transmits the energy signal to the energy receiving device of the energy delivery system to obtain an energy signal for the electronic product. However, during the transmission, the inductor of the resonator causes energy loss, thus integrating the inductor and the feed coil into a metal coil. However, the metal coil satisfies the inductance value of the inductor to increase its number of turns, so that the magnetic flux of the metal coil is relatively increased, and the mutual inductance between the metal coil and the resonator and the coupling amount between the metal coil and the resonator become larger. Causes a mismatch between the metal coil and the resonator impedance. To achieve an impedance match, it is necessary to increase the spacing between the metal coil and the resonator to reduce the mutual inductance of the metal 3 201039528 coil and the resonator, which also increases the volume of the energy transfer system. SUMMARY OF THE INVENTION In view of the above, it is an object of the present invention to provide an energy transfer system. The energy transmission system integrates the feed coil and the inductor into a metal coil, and divides the metal coil into two parts, and respectively winds in different directions to reduce the equivalent magnetic flux of the metal coil after the current is flowed. Thus, the impedance between the metal coil and the resonator is matched to each other without increasing the distance between the metal coil and the resonator, which further reduces the volume of the energy transmission system. According to an aspect of the invention, an energy transfer system is proposed. The energy transmission system includes an energy transmission end device and an energy receiving end device, and the energy transmission end device includes a first metal coil, a first capacitor, and a first resonator. The first metal coil has a first portion and a second portion, the first portion is wound in a first direction and has N匝, and the second portion is wound in a second direction and has a meandering, A portion is adjacent to the second portion, and the first metal coil is used to achieve an equivalent inductance and a first coupling circuit, and the Ν and Μ are positive real numbers. The first capacitor is configured to receive the input energy signal, and the first capacitor and the equivalent inductor form an inductor-capacitor resonator for converting the first internal energy signal according to the input energy signal and providing the first internal energy signal to the first coupling circuit. A first internal energy signal on the first coupling circuit is coupled to the first resonator such that the first resonator has a second internal energy signal. The second internal energy signal is coupled to the energy receiving device such that the energy receiving device has a third internal energy signal. In accordance with another aspect of the present invention, an energy transfer device is provided for wirelessly providing an output energy signal to an energy receiving device using 201039528. The energy transfer device includes a first metal coil, a first capacitor, and a first resonator. The first metal coil has a first portion and a second portion, the first portion is wound in a first direction and has N匝, and the second portion is wound in a second direction and has a meandering, A portion is adjacent to the second portion, and the first metal coil realizes an equivalent inductance and a first coupling circuit, and the Ν and Μ are positive real numbers.

The first resonator, the first internal energy signal of the first coupling circuit is coupled to the first resonator such that the first resonator has a second internal energy signal. The energy receiving end device, the second internal energy signal is coupled to the energy receiving end device such that the energy receiving end device has a third internal energy signal. An embodiment will be described below. Referring to Figure 1, a block diagram of an energy transfer system in accordance with one embodiment of the present invention is shown. The energy transmission system 1A includes an energy transmission end device 1A and an energy receiving end device 30. The energy transmission end device 10 includes a metal coil M1, a capacitor C1, and a resonator 12. The capacitor C1 and the metal coil M1 are coupled to each other, and the capacitor C1 receives the input energy signal Pi. For example, the input energy signal Pi is a square wave energy signal. Please refer to Fig. 2, which is a detailed circuit diagram of the energy transfer system of Fig. 1. The metal coil M1 is used, for example, to realize the equivalent inductance L1 and the coupling circuit Cpl. The equivalent inductor L1 and the capacitor C1 form an inductor-capacitor resonator 14 for converting the internal energy signal Pa according to the input energy signal Pi and providing the internal energy signal Pa to the coupling circuit Cpl. For example, the internal energy signal Pa is a sine wave energy signal. The input energy signal of this embodiment is not limited thereto. In other examples, the energy signal Pa may also be a triangular wave or other waveform signal. The energy signal Pa on the coupling circuit Cpl is coupled to the resonator 12 such that the resonator 12 has an internal energy signal Pb. For example, the resonator 12 includes a metal coil M2 and a capacitor C2. One end of the metal coil M2 is coupled to one end of the capacitor C2, and the other end of the metal coil M2 and the capacitor C2 is coupled to the contact A1 and the contact A2, respectively. The contact A1 and the contact A2 can be connected to the ground. In another example, the contact A1 and the contact A2 are not connected to the 201039528 to the ground. The metal coil M2 is actually a capacitor resonator. The internal energy device 30 on the oscillating device 2 is realized by (4), and the internal energy device 30 on the oscillating device 2 is configured to enable the energy to reach the coupling port to the receiving 糨. In the energy receiving (4), there is an internal energy signal. For example, Receive & Device 3 () includes a total. The internal resonator θ w of the resonator 12 is connected to the resonator 32 of the circuit j such that the internal energy 4 / 2 on the energy receiving end device 3 〇 32 has an internal energy signal h. Resonator ο circuit 34 can be coupled to coupling circuit 34 such that it is coupled to provide a rounded energy signal P〇. For example, the end of the resonator 3 metal _M3 and the capacitor and the other end of the capacitor C3 are the ends of C3, the metal coil M3 ^ knife is coupled to the contact A3 and the contact Α4. Wherein, ^ point A3 and contact point 可4 can be connected to the mantle 4 points and the contact point Α4 can also not be connected to a "in the example, the connection point Α and the capacitor C3 form a salty metal coil Μ3 to achieve equivalent inductance, electric valley formation Inductance and capacitance resonators. Ο For example, the metal coil M1 needs to effectively realize the equivalent inductance L1 and the line of the light-emitting circuit ^^ value with a metal with a high number of turns. Traditionally, it has a more "coil energization". After that, the higher magnetic, u-sen, and the mutual inductance between the coil and the resonator will be generated, and the spacing will be increased correspondingly to make the metal _ and != ground drop match each other. In one example, the two coils of the metal coil are burned to reduce the metal coil, and the same mutual inductance value is maintained. The distance between the two wires, such as M1 and the resonator 12, can correspondingly decrease. The metal line and the resonator 12 can still achieve impedance matching. Next, let's take a look at, for example, 1 7 201039528. Please refer to Fig. 3A, which shows an example of the metal coil of Fig. 2. The metal coil M1 has a first portion S1 and a second portion (4) wound in a direction IH and having an N resistance, the second portion being twisted in the direction D2, and having a μ匝, the first portion S1 being The second part, S2, is adjacent, and the Ν and Μ are positive real numbers. For example, if the metal coil originally has five turns, it is divided into a part / a part si and a second part S2, and has three turns and two turns, respectively. The winding direction D1 of the second portion si and the direction D2 of the second portion S2 are, for example, opposite to each other. The magnetic flux generated by the first portion S1 and the second portion S2 after the current flows in the starting end τ1 of the first portion si and flows in the direction D1 and flows out at the terminal T2 of the second portion S2 and from the direction D2. On the contrary, the equivalent magnetic flux of the metal coil M1 substantially corresponds to the magnetic flux of one turn of the metal coil. Thus, the pitch between the metal coil M1 and the resonator 12 can be correspondingly lowered due to the decrease in the coupling amount, and the metal coil M1 and the resonator ι2 can be impedance-matched because the mutual inductance values are still equal. Although the first portion S1 and the second portion s2 of the present embodiment are described as having different numbers of turns, the present invention is not limited thereto. For example, the first portion S1 and the second portion S2 may have the same number of turns. When the first portion S1 and the second portion S2 have the same number of turns, the equivalent magnetic flux generated by the metal coil M1 approaches zero. Thus, the energy transmitting end device 10 can have a lower electromagnetic energy as a whole. In this way, the energy transmission end device 10 can be more easily conformed to the Electromagnetic Interference (EMI) regulations of the related products. A detailed explanation is given below. 201039528 Please refer to FIG. 2 and FIG. 3B simultaneously, and FIG. 3B is a side view showing an example of the metal coil of FIG. 2 on one side of the resonator. The resonator 12 is located on the same plane as the metal coil M1, and the pitch of the metal coil M1 and the resonator 12 is substantially zero. The axis of the resonator 12 is substantially parallel to the axis of the metal coil M1. For example, the axis of the resonator 12 is substantially parallel to the axis of the first portion S1 and the second portion S2 of the metal coil M1. This is not a limitation. For example, the metal coil M2 of the resonator 12 is in the same current direction as the first portion S1 of the metal coil M10, which produces a magnetic flux in the first direction. The current direction of the metal coil M2 and the second portion S2 of the metal coil M1 is opposite to the first portion S1 (that is, the current direction of the metal coil M2), which respectively generates the magnetic flux in the second direction and the magnetic flux in the first direction, The first and second directions are opposite to each other. In this example, magnetic fluxes of the same direction are coupled to each other to generate a positive magnetic coupling amount, and magnetic fluxes of opposite directions are combined with each other to generate a magnetic coupling amount of a negative polarity. For example, the magnetic energy coupling amount generated by the first portion S1 and the region b defined by the metal coil M2 and the magnetic energy surface combined amount generated by the second portion S2 and the region d defined by the metal coil M2 have the first Polarity (for example, positive polarity). The amount of magnetic energy coupling generated by the region a defined by the first portion S1 and the metal coil M2 has the same amount as the amount of magnetic energy coupling generated by the second portion S2 and the region c defined by the second portion S2 and the metal coil M2. Bipolar (for example, negative polarity). The equivalent coupling amount of the metal coils M1 and M2 is determined by the sum of the amounts of magnetic energy generated by the aforementioned regions a-d, and the amount of the equivalent magnetic energy coupling of the metal coils M1 and M2 can be changed correspondingly by the area of the adjustment region a_d. However, it is also possible to adjust the polarity of the magnetic energy coupling amount generated by the region ad by adjusting the polarity of the magnetic coupling amount of the region ad, and then change the equivalent magnetic energy coupling amount of the metal coil Mi and M2. Let me give another example - the description is as follows. Referring to Fig. 4, a side view of another example in which the metal coil of Fig. 2 is on one side of the resonator is shown. Please refer to FIG. 3B and FIG. 4 simultaneously. For example, it is assumed that the current direction is the same as that described in FIG. 3 'Compared to the area a and the area b 'the metal coil M2A and the area defined by the first portion S1A are, for example, only have Single polarity (eg, positive polarity) compared to area c and area d 'metal coil M2A and area a2 defined by second part siA
