Description

Technical Field

[0001] This invention provides a radial magnetizing magnet assembly with high charging efficiency, belonging to the technical field of magnetizing magnet assemblies. Background Technology

[0002] The wireless charging magnet is an important component in wireless charging devices, providing magnetic attraction for wireless chargers. The magnetic charging magnet component is widely used in wireless charging of mobile phones and other devices.

[0003] Existing magnet components can basically meet the needs of normal wireless charging. However, in order to ensure the magnet has a high attraction force, the magnet is often relatively thick. Furthermore, the magnet has relatively poor magnetic properties after being magnetized, resulting in low charging efficiency and energy loss.

[0004] Based on this, the present invention provides a radial magnetizing assembly with high charging efficiency. Utility Model Content

[0005] The technical problem solved by this invention is that it is difficult to ensure that the magnet is thin while achieving high adsorption force. The magnetized magnet has relatively poor magnetic properties, resulting in low charging efficiency and energy loss.

[0006] To solve the technical problem, the technical solution provided by this utility model is as follows: a radial magnetizing assembly with high charging efficiency, comprising a transparent silicone PET protective film, a red PET film on the top of the transparent silicone PET protective film, a magnet on the top of the red PET film, the magnet having a thickness of 0.3-0.35mm, 3M double-sided adhesive on the top of the magnet, a blue PET release film on the top of the 3M double-sided adhesive, and an opening on one side of the magnet on the red PET film.

[0007] Furthermore, the thickness of the transparent silicone PET protective film and the blue PET release film is 0.075 mm.

[0008] Furthermore, the thickness of the red PET film is 0.1 mm.

[0009] Furthermore, the thickness of the 3M double-sided adhesive is 0.05 mm.

[0010] Furthermore, the red PET film has outer and inner perforations. The outer perforations are formed in the same shape as the magnet and are open rings.

[0011] The beneficial effects of this utility model are:

[0012] This invention first assembles the components without magnetism, applies a protective film, and then places them in a specific magnetizer for magnetization. The magnetization direction is unconventional radial magnetization, with lateral adsorption. The magnetic adsorption positions are accurate, which can improve alignment precision, increase charging efficiency, and reduce energy loss. The magnets are high-grade N56, which are both ultra-thin and have high adsorption force, resulting in a significantly stronger magnetic attraction effect than ordinary products.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] According to the appendix Figure 1 , 2 As shown in Figure 3: This utility model provides a radially magnetized magnet assembly with high charging efficiency: it includes a transparent silicone PET protective film 1 with an adhesiveness of 100-150g; a red PET film 2 on top of the transparent silicone PET protective film 1, which is non-adhesive and silicone oil-free for release; a magnet 3 on top of the red PET film 2, noting the magnetization direction; the bare magnetic Gauss must be ≥1000±200GSN / S; the thickness of the magnet 3 is 0.3-0.35mm; a 3M double-sided adhesive 4 on top of the magnet 3; a blue PET release film 5 on top of the 3M double-sided adhesive 4, with a release force of 3g; and an opening 8 on one side of the red PET film 2. 2 has an outer perforation 6 and an inner perforation 7. The outer perforation 6 is formed with the same overall shape as the magnet 3. The outer perforation 6 is an open ring shape. The magnet 3 is a high-grade N56. The thickness of the magnet 3 can be 0.3-0.35mm, and it is ultra-thin to ensure the magnet's attraction force. The magnet can ensure that the charger and the device's charging interface are accurately aligned and firmly attracted together, preventing charging interruption due to poor contact. The assembly-before-magnetization scheme is used. The magnets are assembled without magnetism first, a protective film is applied, and then they are placed in a special magnetizer to be magnetized. This effectively avoids the problem of the last magnet always being magnetized when magnetized first and then assembled, so as to prevent all the previous magnets from being attracted together again.

[0019] As an optional embodiment, the thickness of the transparent silicone PET protective film 1 and the blue PET release film 5 is 0.075mm, the thickness of the red PET film 2 is 0.1mm, the thickness of the 3M double-sided adhesive 4 is 0.05mm, and the total thickness of the radially magnetized magnet assembly is strictly controlled.

[0020] This invention first assembles the components without magnetism, applies a protective film, and then places them in a specific magnetizer for magnetization. The magnetization direction is unconventional radial magnetization, with lateral adsorption. The magnetic adsorption positions are accurate, which can improve alignment precision, increase charging efficiency, and reduce energy loss. The magnet 3 can be both thin and have high adsorption force, with a magnetic adsorption effect that is significantly stronger than that of ordinary products.

[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
