Description

Technical Field

[0001] This utility model relates to the field of wireless charging coil technology, specifically a low-energy wireless charging receiving coil. Background Technology

[0002] Wireless charging receiving coils operate based on the principle of electromagnetic induction. The transmitting coil generates an alternating magnetic field. When the receiving coil is in this magnetic field, the magnetic flux changes. According to Faraday's law of electromagnetic induction, an induced electromotive force is generated in the receiving coil, thereby converting magnetic field energy into electrical energy to power electronic devices.

[0003] With the widespread use of electronic devices, wireless charging technology has received increasing attention due to its convenience. However, in the existing wireless charging receiving coil, due to the high resistance of the coil and the design of the structure, there will be a large loss during energy transmission, which further reduces the energy conversion efficiency and makes the charging process require higher energy consumption. Therefore, a low-energy wireless charging receiving coil is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a low-energy wireless charging receiver coil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-energy wireless charging receiving coil, including a support body, a fixed base is provided on the top of the support body, a receiving coil body is sleeved on the outer surface of the fixed base, a magnetic core is sleeved on the inner side of the support body, and several sets of heat dissipation holes are opened at the bottom of the support body.

[0006] As described above, the receiving coil body includes a copper core, the outer surface of which is covered with a plating layer, and the outer surface of which is covered with an insulating layer.

[0007] As described above, the two ends of the magnetic core pass through the support body, and the middle part of the magnetic core passes through the fixing seat and is fixed with glue.

[0008] As described above, the top of the magnetic core is flush with the top of the receiving coil body, and the receiving coil body is a spirally wound circle.

[0009] The insulating layer described above is made of polyimide, and the thickness of the insulating layer is 5-50 μm.

[0010] The aforementioned coating is made of silver and has a thickness of 1–5 μm.

[0011] As mentioned above, the magnetic core is made of nanocrystalline alloy, and both ends of the magnetic core are attached to the outer periphery of the receiving coil body.

[0012] Compared with existing technologies, this low-energy wireless charging receiver coil has the following advantages:

[0013] I. This utility model uses a silver layer to coat the copper core of the receiving coil body, which reduces the coil resistance and reduces power transmission loss by utilizing the higher conductivity of silver; the magnetic core is made of nanocrystalline alloy, which enhances the magnetic field strength of the receiving coil and promotes uniform magnetic field distribution by virtue of its high magnetic permeability, low coercivity and low loss characteristics; the two work together to improve wireless charging efficiency and achieve low-energy and high-efficiency charging.

[0014] II. This utility model utilizes the support body as the basic load-bearing structure. The fixed seat set at the top provides installation support for each component, preventing the receiving coil body from shaking and shifting during operation. The magnetic core passes through the support body at both ends and through the fixed seat in the middle and is fixed with glue, and is firmly installed inside the support body to avoid displacement during operation. This enhances the connection strength between the magnetic core and the fixed seat, ensures the stability of each component, and enables the receiving coil to perform stably during operation.

[0015] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-3As shown, this utility model provides a low-energy wireless charging receiving coil, including a support body 1, a fixing seat 2 is provided on the top of the support body 1, the receiving coil body 3 is sleeved on the outer surface of the fixing seat 2, a magnetic core 4 is sleeved on the inner side of the support body 1, and several sets of heat dissipation holes 5 are opened at the bottom of the support body 1.

[0022] The support body 1 serves as the basic load-bearing structure for the entire receiving coil. A fixed base 2 is provided on its top to provide a support platform for the installation and fixation of other components, ensuring the stability of each component during use. The fixed base 2 prevents the receiving coil body 3 from shaking or shifting during operation. The magnetic core 4 enhances the magnetic field strength of the receiving coil body 3, improving the efficiency of wireless charging. Several sets of heat dissipation holes 5 are provided at the bottom of the support body 1. During wireless charging, the heat dissipation holes 5 can accelerate air circulation and dissipate heat in a timely manner, avoiding the impact of heat accumulation on the device's performance and service life.

[0023] like Figure 3 As shown, the receiving coil body 3 includes a copper core 31, the outer surface of the copper core 31 is covered with a plating layer 32, and the outer surface of the plating layer 32 is covered with an insulating layer 33.

[0024] The core of the receiving coil body 3 is a copper core 31. The copper core 31 has good conductivity and can transmit current efficiently. Furthermore, since the outer surface of the copper core 31 is covered with a plating layer 32, silver has a higher conductivity than copper, which can further reduce the coil resistance, reduce the loss in the power transmission process, and improve the efficiency of wireless charging.

[0025] like Figure 1 , 2 As shown, the two ends of the magnetic core 4 pass through the support body 1, and the middle part of the magnetic core 4 passes through the fixing seat 2 and is fixed with glue.

[0026] The magnetic core 4 can be securely installed inside the support body 1, preventing the magnetic core 4 from shifting during operation. The middle part of the magnetic core 4 passes through the fixing base 2 and is fixed with glue. The glue fixation further enhances the connection strength between the magnetic core 4 and the fixing base 2, ensuring that the magnetic core 4 can stably play the role of enhancing the magnetic field when the receiving coil is working.

[0027] like Figure 1 , 2 As shown, the top of the magnetic core 4 is flush with the top of the receiving coil body 3, and the receiving coil body 3 is a spirally wound circle.

[0028] By aligning the top of the magnetic core 4 with the top of the receiving coil body 3, this design allows the magnetic core 4 to work better with the receiving coil body 3, fully leveraging the magnetic core 4's ability to enhance the magnetic field and ensuring that the magnetic field is evenly distributed around the receiving coil body 3, thereby improving the efficiency of wireless charging.

[0029] like Figure 3 As shown, the insulating layer 33 is made of polyimide, and the thickness of the insulating layer 33 is 5-50 μm.

[0030] The insulation layer 33 is designed to be made of polyimide, which has excellent insulation properties, high temperature resistance and chemical stability. It can work stably for a long time under harsh conditions such as high temperature and complex electromagnetic environment, effectively protecting the internal copper core 31 and silver layer.

[0031] like Figure 3 As shown, the plating layer 32 is made of silver, and the thickness of the plating layer 32 is 1 to 5 μm.

[0032] The plating layer 32 is designed to be made of silver. The high conductivity of silver can significantly reduce the coil resistance and reduce the heat loss of electrical energy during transmission, thereby achieving the goal of low energy consumption. The thickness of plating layer 32 is 1 to 5 μm. Within this thickness range, the conductivity advantage of silver can be fully utilized while the cost can be effectively controlled.

[0033] like Figure 2 As shown, the magnetic core 4 is made of nanocrystalline alloy, and the two ends of the magnetic core 4 are attached to the outer periphery of the receiving coil body 3.

[0034] The magnetic core 4 is made of nanocrystalline alloy, which has excellent magnetic properties such as high permeability, low coercivity and low loss. It can effectively enhance the magnetic field strength of the receiving coil, improve the efficiency of wireless charging, and realize low-energy and high-efficiency wireless charging function.

[0035] Working principle:

[0036] The coating 32 covering the outer surface of the copper core 31 further reduces the coil resistance due to the higher conductivity of silver, greatly reducing power transmission loss and significantly improving wireless charging efficiency. Meanwhile, the magnetic core 4, made of nanocrystalline alloy, effectively enhances the magnetic field strength of the receiving coil body 3 due to its high permeability, low coercivity, and low loss characteristics, and promotes uniform magnetic field distribution, further improving wireless charging efficiency. In addition, several sets of heat dissipation holes 5 at the bottom of the body 1 accelerate air circulation during wireless charging, dissipating the heat generated during operation in a timely manner and avoiding the impact of heat accumulation on device performance and lifespan. The collaborative work of multiple components ultimately achieves low-energy and high-efficiency wireless charging.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
