Description

Technical Field

[0001] The utility model relates to the technical field of energy transmission, in particular to a double-vibrator energy transmission module. Background Art

[0002] Energy can be efficiently transferred between two objects with the same vibration frequency, while objects with different vibration frequencies have almost no effect. The coils at the transmitter and receiver are adjusted into a magnetic resonance system. When the frequency of the oscillating magnetic field generated by the transmitter is the same as the natural frequency of the receiver, resonance occurs at the receiver, thereby achieving energy transmission. According to the characteristics of resonance, energy transmission is carried out within such a resonance system and will not have any effect on objects outside the resonance system.

[0003] When the transmitter is powered on, it does not emit electromagnetic waves, but only forms a non-radiative magnetic field around it. This magnetic field is used to communicate with the receiver and stimulate the resonance of the receiver, thereby transmitting energy at a very low cost.

[0004] The dual-vibrator energy transmission module adopts a single-feed design concept, with ceramics as the main radiation source, a microstrip line series structure, and a dual ceramic unit structure to enhance the radiation width and gain size.

[0005] In the prior art, during the use of energy transmission, when a dual-vibrator energy transmission module is used, there is often a risk of point array due to the interconnection of an external high-frequency wiring harness and a corresponding SMA head, which affects actual use; therefore, we have made improvements to this and proposed a dual-vibrator energy transmission module.

[0034] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0035] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the present invention to be protected, but only represents some embodiments of the present invention.

[0037] like Figure 1-2 As shown, this embodiment proposes a dual-vibrator energy transmission module, including a transmission module body 1 and a vibrator body 2, the outer end of the vibrator body 2 is provided with a protective cover, the outer end of the vibrator body 2 is provided with a protective cover, a PCB board 17 is provided in the center of the transmission module body 1, a welding foot 16 is welded at the left end of the PCB board 17, an SMA head 15 is fixed to the outer end of the welding foot 16, a strong magnetic sheet and a disassembly port are embedded in the bottom end of the transmission module body 1, and the bottom end of the transmission module body 1 is wrapped with an anti-slip pad.

[0038] Similar products on the market are all connected to other devices through a high-frequency wire with an SMA head 15. In actual engineering use, the high-frequency wire harness is easily broken. In this embodiment, the SMA head 15 is directly double-sided welded on the PCB board 17, which ensures the stability and reliability of the structure and eliminates the quality problems caused by the breakage of the high-frequency wire harness;

[0039] A strong magnetic sheet is embedded and installed on the back of the transmission module body 1, and an anti-skid pad is wrapped around the outer end of the strong magnetic sheet, so that the product is easy to install and the position is stable and not easy to slide;

[0040] By embedding two disassembly openings on the back of the transmission module body 1 , the back plate of the transmission module body 1 can be easily removed to check the internal PCB board 17 .

[0041] The working principle of the transmission module body 1 is as follows: 915MHZ is used as the antenna radiation center point, a single feed design concept is adopted, and ceramic is used as the main radiation source of the antenna, so that it can ensure the best signal in a plane size of 65X65mm. Considering the usage scenario, a microstrip line series structure is used to adopt a double ceramic unit structure to enhance the radiation width and gain size. From the structural section, we use a 50Ω impedance line method so that it can be fixed on the PCB board 17 through the SMA head 15. This method is not only structurally stable and easy to install, but also has low transmission loss.

[0042] In terms of performance, this product uses a circularly polarized antenna, and its electromagnetic wave electric field and magnetic field show spiral radiation, so in practical applications it has strong resistance to multipath interference and can improve signal stability and reliability; it is also widely applicable and not restricted by the use environment, and can achieve transmission in different signal directions; furthermore, its signal coverage is wide and radiates in an apple-shaped manner, reducing radiation dead angles; finally, the high-gain ceramic material design and matching antenna array solution can meet both wide lobe and high gain requirements.

[0043] like Figure 3-7 As shown, this embodiment proposes a dual-oscillator energy transmission module. Furthermore, a coil 3 is provided at the inner end of the protective cover, a positioning frame 13 is provided at the upper end of the coil 3, a positioning groove 14 is provided at the inner end of the positioning frame 13, a linkage spiral frame 9 is provided at the lower end of the linkage spiral frame 9, a linkage leather strip 8 is provided at the inner end of the linkage leather strip 8, a storage rod 10 is provided at the inner end of the linkage leather strip 8, an energy storage rod 10 is wrapped with an energy storage electric ring 11 at the outer end of the energy storage electric ring 11, a linkage rod 12 is provided at the outer end of the linkage rod 12, an insulating ring 7 is provided at the lower end of the insulating ring 7, an insulating rod 6 is provided at the lower end of the insulating rod 6, a spare line segment 4 is provided at the lower end of the spare line segment 4, and a coupling frame 5 is provided at the starting end of the spare line segment 4.

[0044] The tail end of the coil 3 is electrically connected to the spare line segment 4 via a coupling frame 5 , and the coupling frame 5 is used for electrical conduction between the tail end of the coil 3 and the spare line segment 4 .

[0045] The number of the spare line segments 4 is set to four groups, the four groups of spare line segments 4 are wrapped around each other, the upper ends of the four groups of spare line segments 4 are respectively fixed with insulating rods 6, and each group of spare line segments 4 is fixed to three groups of insulating rods 6.

[0046] The upper ends of each three groups of insulating rods 6 are fixed to a group of insulating rings 7 , and the center of the insulating ring 7 is fixed by a linkage rod 12 . The linkage rod 12 slides up and down along the positioning groove 14 , and the center of the linkage rod 12 is fixed by the energy storage electric ring 11 .

[0047] The energy storage electric coil 11 slides up and down along the energy storage rod 10 , and the energy storage rod 10 and the energy storage electric coil 11 are in contact with each other to supply power. The energy storage rod 10 is used to collect the excess mechanical energy of the vibrator body 2 and convert it into electrical energy.

[0048] One end of the linkage leather strip 8 is fixed to a power assembly, and the power assembly is a micro push rod.

[0049] The linkage leather strip 8 moves spirally along the linkage spiral frame 9, and the spare line segment 4 slides up and down along the linkage spiral rod.

[0050] The linkage spiral frame 9 penetrates through the upper and lower outer surfaces of the positioning frame 13 , and the cross-sectional size of the lower end of the positioning frame 13 is larger than that of the upper end.

[0051] When using this application: adopt a single feed design idea, use ceramic as the main radiation source of the antenna, so that it can ensure the best signal in a plane size of 65X65mm. Considering the usage scenario, a microstrip line series structure is used to adopt a dual ceramic unit structure to enhance the radiation width and gain size. From the structural section, we use a 50Ω impedance line method so that it can be fixed on the PCB board 17 through the SMA head 15. This method is not only structurally stable and easy to install, but also has low transmission loss. When the size of the coil 3 needs to be changed for different transmission requirements, the power component pushes the linkage leather strip 8 to slide along the linkage spiral frame 9, driving the energy storage electric ring 11 wrapped on the energy storage rod 10 to push the insulating rod 6 linkage with the insulating ring 7 through the linkage rod 12. The spare line segment moves downward. In this process, the number of turns of the exposed linkage spiral frame 9 from the inside to the outside is the number of turns that the coil 3 needs to increase according to how much the linkage leather strip 8 is pushed. The spare line segment 4 connected to the insulating rod 6 is pushed downward by the insulating ring 7, driving the coupling frame 5 and the corresponding coil 3 tail end to wrap around each other. At this time, the coupling frame 5 can facilitate the conductive connection between the spare line segment 4 and the original coil 3, which is convenient for changing the number of turns of the coil 3 under different transmission conditions.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
