Description

Cases for portable electronic devices

The present invention relates to a casing of a portable electronic device, in particular to a casing of a portable electronic device that combines functional components with the casing through a binding layer.

Existing portable electronic devices use a casing and a panel to jointly hold a sealing gasket, so that the sealing gasket is pressed against the casing and the panel in a contact manner to achieve waterproof or dustproof effects. Since the sealing gasket is not fixed on the casing or the panel, the sealing gasket can easily fall off during the assembly or disassembly of the casing and the panel. In addition, the sealing gasket is also susceptible to inaccurate human assembly and cannot be in close contact with the chassis or panel, resulting in poor waterproof or dustproof effects.

In order to achieve the anti-collision effect of existing portable electronic devices, a buffer pad is placed on an outer peripheral surface of the casing. However, the above-mentioned setting method is easily affected by artificial assembly inaccuracies, which may cause the cushion pad to fall off the casing when the portable electronic device is dropped, thereby causing damage to the casing. Another method is to cover the casing and four cushion pads with a shell, and then fix the cushion pads at the four corners of the casing respectively to prevent the cushion pads from falling off. However, the above-mentioned method increases the use cost of the casing and causes the thickness of the portable electronic device to become thicker.

Therefore, one of the objects of the present invention is to provide a casing for a portable electronic device that can overcome at least one disadvantage of the prior art.

Therefore, the casing of the new portable electronic device includes a shell, at least one bonding layer, and at least one functional component.

The shell includes at least one joint surface. The bonding layer is formed on the bonding surface, and the bonding layer contains a material of a chemical element. The functional part is combined with the shell through the bonding layer, and the functional part is made of a material containing the chemical element.

In some embodiments, the chemical element is silicon.

In some embodiments, the bonding layer includes silicon or silicon dioxide.

In some implementations, the functional component is made of silicone.

In some implementations, the bonding layer has a modified surface bonded to the functional component.

In some implementations, the joint surface is a bearing surface in a surrounding and closed shape, the bonding layer is in a surrounding and closed shape, and the functional component is a sealing gasket in a surrounding and closed shape.

In some implementations, the joint surface is an outer peripheral surface in a surrounding and closed shape, the bonding layer is in a surrounding and closed shape, and the functional component is a cushioning pad in a surrounding and closed shape.

In some embodiments, the shell includes four joint surfaces spaced apart from each other, each of the joint surfaces is an angular surface, and the casing includes four bonding layers respectively formed on the joint surfaces, and are respectively bonded to Each of the four functional parts of the bonding layer is a cushion.

In some implementations, the joint surface is located on the outer peripheral surface of the shell, and the functional component is a cushion.

In some implementations, the joint surface is located on the inner peripheral surface of the shell, and the functional component is a sealing gasket.

The new type has at least the following effects: fast manufacturing speed and capable of mass production. In addition, the functional component can be firmly fixed on the joint surface of the shell through the binding layer, so that the functional component will not fall off from the shell.

The base wall 11 has a long wall shape, for example. The surrounding wall 12 is formed on the outer periphery of the base wall 11 and has an inner peripheral surface 121 and an outer peripheral surface 122 opposite to the inner peripheral surface 121 . The outer peripheral surface 122 is in a closed shape and has four corner portions 123 spaced apart from each other. In the first embodiment, each angular surface 123 is an arc-shaped surface as an example, but it is not limited to this. Each corner surface 123 may also be an L-shaped right-angled surface. The load-bearing wall 13 extends inwardly from the inner peripheral surface 121 of the surrounding wall 12 and is spaced apart from the base wall 11 . The bearing wall 13 is in a closed shape and has a bearing surface 131 opposite to the base wall 11 . The bearing surface 131 is in a closed shape and is connected to the inner peripheral surface 121 . In this first embodiment, the bearing surface 131 of the bearing wall 13 is a joint surface, and the joint surface is located on the inner peripheral surface 121 of the shell 1 .

Referring to FIG. 1 , FIG. 5 and FIG. 6 , in step S2 , a bonding layer 2 is formed on the bearing surface 131 of the shell 1 . The bonding layer 2 contains a chemical element material. The bonding layer 2 has a layer 21 opposite to the bearing surface 131 . Since the bearing surface 131 is in a surrounding and closed shape, the bonding layer 2 formed on the bearing surface 131 is also in a surrounding and closed shape. In this first embodiment, the chemical element is silicon (Si) as an example but is not limited thereto. The bonding layer 2 contains silicon or silicon dioxide (SiO ₂ ) and is plated on the bearing surface 131 of the shell 1 by, for example, physical vapor deposition (PVD), chemical vapor deposition (CVD) or coating. The shell 1 is made of a material that can be plated with the chemical element, such as a metal material but is not limited thereto.

Referring to FIG. 1 , FIG. 6 and FIG. 7 , in step S3 , surface modification is performed on the layer 21 of the bonding layer 2 so that the layer 21 is transformed into a modified surface 22 . The layer 21 of the bonding layer 2 can be surface-modified through oxygen ion treatment, ultraviolet rays or plasma, for example, and then transformed into a modified surface 22 .

Referring to Figures 1, 8 and 9, in step S4, a functional component 3 is provided, and the functional component 3 is made of a material containing the chemical element. That is to say, the functional component 3 and the bonding layer 2 are both made of materials containing silicon. The functional component 3 is combined with the modified surface 22 of the bonding layer 2 so that the functional component 3 is bonded to the shell 1 via the bonding layer 2 .

In the first embodiment, the functional component 3 is made of silicone, for example, but is not limited to this. Specifically, the functional part 3 is made of liquid silicone rubber (LSR). In addition, in the first embodiment, the functional component 3 is formed on the modified surface 22 of the bonding layer 2 so that the functional component 3 is directly and fixedly bonded to the modified surface 22 of the bonding layer 2 . The functional component 3 can be formed on the modified surface 22 of the bonding layer 2 by, for example, hot pressing, injection molding, or coating methods, and can be directly bonded to the modified surface 22 . When the functional component 3 is combined with the modified surface 22 of the bonding layer 2 , the casing 100 of a portable electronic device is completed. Since the bonding layer 2 is in a surrounding and closed shape, the functional component 3 formed on the bonding layer 2 is also in a surrounding and closed shape. Thereby, the functional part 3 can function as a sealing gasket.

The bonding layer 2 is formed by, for example, physical vapor deposition (PVD), chemical vapor deposition (CVD) or coating method to form a thin film on the bearing surface 131 of the shell 1, so that the bonding layer 2 can be directly and fixedly bonded to the bearing surface 131 to enhance the bonding strength. Since the physical vapor deposition method can coat hundreds of shells 1 with the bonding layer 2 at one time, the manufacturing speed is fast, mass production can be achieved, and the manufacturing cost can be reduced. In addition, since the bonding layer 2 and the functional part 3 are both made of materials containing the chemical element, the functional part 3 is easily bonded to the bonding layer 2 and can be firmly fixed on the bonding layer 2, thereby making the function The component 3 can be firmly coupled and fixed to the bearing surface 131 of the shell 1 through the binding layer 2 . Thereby, the shell 1 does not need to design a gripping structure such as barbs or grooves to cover the functional component 3 , which can reduce the design complexity of the shell 1 structure and the manufacturing cost of the shell 1 . Furthermore, by performing surface modification on the bonding layer 2 so that the layer 21 (as shown in FIG. 6 ) is transformed into a modified surface 22, the stability of the functional component 3 being bonded to the bonding layer 2 can be further improved.

Referring to FIG. 10 , when a panel 4 and the shell 1 of the portable electronic device casing 100 are assembled and fixed together, for example, by engaging hooks and slots, the panel 4 will be pressed tightly against the casing 100 of the portable electronic device. On the functional part 3, the functional part 3 plays a sealing role to prevent water or dust from penetrating from the external environment into an internal space jointly defined by the shell 1 and the panel 4. Since the functional component 3 is fixed on the bearing surface 131 through the bonding layer 2 instead of pressing against the bearing surface 131 through contact, the waterproof and dustproof effect of the functional component 3 between the shell 1 and the panel 4 can be effectively improved. , it can also prevent the functional part 3 from falling off the shell 1 during the assembly or disassembly of the panel 4 and the shell 1 .

It should be noted that the material used to manufacture the bonding layer 2 in the first embodiment is selected based on the material of the functional component 3 . That is to say, the chemical element contained in the material of the bonding layer 2 must be the same as the chemical element contained in the material of the functional component 3, so that the functional component 3 can be successfully bonded to the bonding layer 2. It can be understood that in other implementation aspects of the first embodiment, the chemical element contained in the material of the functional component 3 and the bonding layer 2 can also be a chemical element other than silicon, and is not limited to silicon.

The difference lies in the joint surface of the casing 1 and the functions and functions of the functional component 3 .

In the second embodiment, the outer peripheral surface 122 of the housing 1 surrounding the wall 12 is a joint surface, that is to say, the joint surface is located on the outer peripheral surface 122 of the housing 1 . The bonding layer 2 is formed on the outer peripheral surface 122 of the shell 1 . Since the outer peripheral surface 122 is in a surrounding and closed shape, the bonding layer 2 formed on the outer peripheral surface 122 and the functional component 3 formed on the bonding layer 2 are also in a surrounding and closed shape. Thereby, the functional component 3 can function as a cushion, so that the casing 100 of the portable electronic device can achieve an anti-collision effect.
