Technical Field

[0001] The utility model relates to the technical field of mobile phone accessories, in particular to an ultra-thin Kevlar mobile phone shell. Background Art

[0002] As the performance of smart terminals continues to improve, the components inside smart terminals are becoming more and more sophisticated and complex. Smart terminals are prone to bumps and slips during daily use. In addition, smart terminals are prone to heat up after long-term use. Mobile phone cases can protect mobile phones to a certain extent.

[0003] Existing mobile phone protective cases are mostly made of plastic, silicone and metal, which have defects such as poor drop resistance, heavy shell and poor heat dissipation performance. The thinnest mobile phone case with magnetic suction function is between 1.0 and 1.2 mm thick. The mobile phone case is relatively thick and heavy, and it is not very light when put on the mobile phone.

[0004] Please refer to Figure 1 , shown is an existing mobile phone case 100, including a surface shell 102 made of materials such as plastic, silicone and metal, an interlayer 103 and a bottom shell 100 made of materials such as plastic, silicone and metal. Among them, a through hole is opened on the middle interlayer 103 and a magnet 104 is installed, and after assembly, a mobile phone case 100 with an upper, middle and lower three-layer structure is formed. According to measurement, the thickness of the existing mobile phone case with magnetic suction function is between 1.0-1.2 mm, which is still relatively thick. In addition, the surface shell 102 and the bottom shell 100 are made of materials such as plastic, silicone and metal, which makes the manufactured mobile phone case relatively hard, with poor hand feel and inconvenient to disassemble and assemble.

[0005] In addition, in the existing three-layer structure of the mobile phone case 100, the magnet 104 is embedded between the surface case 102 and the bottom case 100, and the heat dissipation performance is poor. Summary of the invention

[0006] Based on this, in order to solve the above-mentioned technical problems in traditional technologies, the utility model proposes an ultra-thin Kevlar mobile phone case that is lighter, thinner, and more flexible. By setting exposed magnetic suction components inside and outside the mobile phone case, it is more conducive to the heat dissipation of the mobile phone and improves the positioning accuracy of wireless charging, thereby enhancing the product usage experience.

[0007] The utility model relates to an ultra-thin Kevlar mobile phone case, comprising a main shell body, wherein the main shell body comprises a Kevlar woven inner shell layer, a Kevlar woven outer shell layer and a magnetic attraction component, wherein a first through hole having the same shape as the magnetic attraction component is provided on the Kevlar woven inner shell layer, a second through hole having the same shape as the first through hole is provided on the Kevlar woven outer shell layer, and the magnetic attraction component is built in the first through hole and the second through hole.

[0008] One side of the magnetic attraction component is flush with the Kevlar braided inner shell layer, and the other side is flush with the Kevlar braided outer shell layer. The magnetic attraction component includes a magnet and a resin gasket that supports the magnet.

[0009] In terms of assembly, the ultra-thin Kevlar mobile phone case also includes an ultra-thin transparent glass fiber layer, which is covered on the magnet and bonded between the Kevlar woven inner shell layer and the Kevlar woven outer shell layer during a hot pressing process, and the edge of the resin gasket is bonded to the Kevlar woven inner shell layer in the first through hole through a hot pressing process.

[0010] Preferably, the ultra-thin transparent glass fiber layer has a thickness ranging from 0.05 mm to 0.1 mm.

[0011] Preferably, the thickness of the Kevlar braided inner shell layer and the Kevlar braided outer shell layer ranges from 0.1 mm to 0.3 mm.

[0012] The size of the main shell matches the size of the mobile phone, and the mobile phone case also includes a left frame, a right frame, a top frame and a bottom frame distributed along the edge of the main shell.

[0013] The top frame and the bottom frame are both provided with at least one notch for providing elastic force.

[0014] A camera window is provided on the main shell, and a protection ring is arranged on the camera window.

[0015] In this embodiment, there are many ways to implement the magnet. The shape of the magnet is square, round, elongated, annular, or irregular. The shapes of the first through hole and the second through hole are the same as the shape of the magnet.

[0016] When the magnet is an annular magnet, the main shell includes a Kevlar woven outer shell sheet and a Kevlar woven inner shell sheet arranged inside the annular magnet, the ultra-thin transparent glass fiber layer is covered on the annular magnet and the Kevlar woven outer shell sheet, and during the hot pressing process, the edge of the ultra-thin transparent glass fiber layer is bonded between the Kevlar woven inner shell layer and the Kevlar woven outer shell layer.

[0017] When the magnet is a ring magnet, the ring magnet includes 4, 6, 18 or 36 magnet blocks.

[0018] The beneficial effects of the utility model are:

[0019] The ultra-thin Kevlar mobile phone case of the utility model adopts Kevlar woven material for both inner and outer materials. The Kevlar woven material has very good thermal stability, fire resistance, chemical resistance, insulation, high strength and modulus. The mobile phone case can be made thinner and lighter, and has better flexibility, and is also convenient for disassembly and assembly on the mobile phone.

[0020] The ultra-thin Kevlar mobile phone case of the utility model has magnet particles of the magnetic attraction component that can be directly seen inside and outside, and the mobile phone case design with exposed magnets is more beautiful. In addition, the design of exposed magnet particles has no sandwich structure, which can reduce the thickness of the mobile phone case as much as possible while having the magnetic attraction function, making the mobile phone case lighter and thinner.

[0021] The ultra-thin Kevlar mobile phone case of the utility model has two sides of the magnetic particles not covered by a thick shell, and the magnetic field distribution can improve the positioning accuracy during magnetic charging. At the same time, the two sides of the magnetic particles are not covered by a thick shell, which does not attenuate the wireless charging efficiency of the bare phone and is also more conducive to the heat dissipation of the mobile phone.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Please refer to Figure 2 , Figure 3 as well as Figure 6 The ultra-thin Kevlar mobile phone case of the utility model comprises a main shell 10 that is consistent with the appearance of the mobile phone. The main shell 10 is formed by bonding a Kevlar braided inner shell layer 101, a Kevlar braided outer shell layer 102 and a magnetic suction component in a mold through a hot pressing process. The magnetic suction component comprises a magnet 3 and a resin gasket 2 that carries the magnet 3. The ultra-thin Kevlar mobile phone case of this embodiment has both inner and outer materials made of Kevlar braided material. Kevlar braided material has very good thermal stability, fire resistance, chemical resistance, insulation, high strength and modulus. The mobile phone case can be made thinner and lighter, and has better flexibility, and is also easy to disassemble and assemble on the mobile phone.

[0033] The Kevlar braided inner shell 101 defines a first through hole 106 having the same shape as the magnetic component. The Kevlar braided outer shell 102 defines a second through hole 108 having the same shape as the first through hole. The magnetic component is installed in the first through hole 106 and the second through hole 108 .

[0034] The design point of the utility model is that the magnetic attraction component is nearly exposed on the mobile phone shell, and the magnetic attraction component is visible at the front and back of the mobile phone shell.

[0035] In one embodiment, in order to maintain a good hand feel, one side of the magnetic component is flush with the Kevlar braided inner shell 101 layer, and the other side is flush with the Kevlar braided outer shell 102 layer. In other functional design embodiments, one side of the magnetic component can be slightly higher or lower than the Kevlar braided inner shell, and the other side can be slightly higher or lower than the Kevlar braided outer shell 102 layer.

[0036] In this embodiment, there are many ways to implement the magnet 3 of the magnetic attraction component. The shape of the magnet can be square, round, elongated, annular, or irregular. The shape of the first through hole 106 and the second through hole 108 is the same as the shape of the corresponding magnet 3.

[0037] When the magnet 3 is a ring magnet, the magnet blocks provided in the ring magnet can be implemented in a variety of ways, for example, the ring magnet includes 4, 6, 18 or 36 magnet blocks. Figure 2 as well as Figure 5The embodiment of 36 magnet blocks shown and Figure 4 An embodiment of 18 magnet blocks is shown.

[0038] The following specific structure of the ultra-thin Kevlar mobile phone case is introduced based on an embodiment of 36 magnet blocks or an embodiment of 18 magnet blocks in which the magnetic attraction component is flush with the Kevlar braided inner shell layer 101 and the Kevlar braided outer shell layer 102.

[0039] Please refer to Figure 2 as well as Figure 3 , the size of the main housing 10 matches the size of the mobile phone. The ultra-thin Kevlar mobile phone case of this embodiment includes a main housing 10 that is consistent with the appearance of the mobile phone. The mobile phone case also includes a left frame 11, a right frame 12, a top frame 13 and a bottom frame 14 distributed along the edge of the main housing 10. The left frame 11 and the right frame 12 are provided with button holes. The top frame 13 and the bottom frame 14 are both provided with at least one notch for providing elastic force. For example, the top frame 13 is provided with a first notch 131 and a second notch 132 for providing elastic force.

[0040] Please refer to Figure 4 as well as Figure 5 A camera window 105 is opened on the main shell 10 , and a protective ring 6 is set on the camera window 105 .

[0041] Please refer to Figure 6 In order to achieve assembly, the ultra-thin Kevlar mobile phone case also includes an ultra-thin transparent glass fiber layer 8.

[0042] Please refer to Figure 7 During assembly, the magnet 3 together with the resin gasket 2 are built into the first through hole 106 and the second through hole 108 which are connected up and down. The ultra-thin transparent glass fiber layer 8 is covered on the magnet 3 and bonded between the Kevlar braided inner shell layer 101 and the Kevlar braided outer shell layer 102 during the hot pressing process. The edge of the resin gasket 2 is bonded to the Kevlar braided inner shell layer 101 in the first through hole 106 through the hot pressing process.

[0043] like Figure 5 As shown, in the embodiment of the annular magnet, the ultra-thin transparent glass fiber layer 8 also needs to cover the Kevlar braided layer set in the middle of the annular magnet. When the magnet 3 is an annular magnet, the main shell 10 includes a Kevlar braided outer shell sheet 107 and a Kevlar braided inner shell sheet set inside the annular magnet. The ultra-thin transparent glass fiber layer 8 covers the annular magnet 3 and the Kevlar braided outer shell sheet 107, and the edge of the ultra-thin transparent glass fiber layer 8 is bonded between the Kevlar braided inner shell layer 101 and the Kevlar braided outer shell layer 102 during the hot pressing process.

[0044] The present technical solution has a magnet 3 built into the exterior surface of the mobile phone case. The production process is as follows: the Kevlar braided inner shell layer 101, the Kevlar braided outer shell layer 102 and the ultra-thin transparent glass fiber layer 8 are cut. The protective film of the Kevlar braided inner shell layer 101 is removed, and the magnet assembly and the ultra-thin transparent glass fiber layer 8 are placed and fixed in position. The protective film of the Kevlar braided outer shell layer 102 is removed, and the Kevlar braided inner shell layer 101 is pasted and placed in a mold for hot pressing.

[0045] In this embodiment, the resin gasket 2 and the ultra-thin transparent glass fiber layer 8 are substantially transparent and very thin. After hot pressing and compounding, the magnet 3 appears to be exposed in the front and rear directions of the main housing 10 .

[0046] In a specific implementation, the thickness of the ultra-thin transparent glass fiber layer 8 is in the range of 0.05 mm to 0.1 mm.

[0047] The thickness of the Kevlar braided inner shell layer 101 and the Kevlar braided outer shell layer 102 ranges from 0.1 mm to 0.3 mm.

[0048] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
