Description

Electronic device and method of manufacturing the same

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to an electronic device and a manufacturing method thereof.

Background

With the widespread of electronic devices such as notebook computers, the demand for the quality of appearance of the notebook computers is also increasing.

At present, in order to pursue the texture, the casing of the notebook computer is usually made of a metal material, such as aluminum or an aluminum alloy casing. Because the corrosion resistance of aluminum or aluminum alloy is poor, the conventional notebook computer usually carries out an anode appearance treatment process on an aluminum or aluminum alloy shell, so that the notebook computer has the appearance of a metal anode, the corrosion resistance of the notebook computer can be enhanced, and the shell of the notebook computer can be more delicate and has a smooth surface.

However, in a scenario that the notebook computer needs to be opened with one hand, the situation that the whole notebook computer is pushed to the rear often occurs when the notebook computer is operated with one hand to open the notebook computer, which may cause a failure in opening with one hand and may cause the notebook computer to fall and be damaged.

Disclosure of Invention

The application provides an electronic device and a manufacturing method thereof, which can be beneficial to realizing the configuration change of the electronic device by one hand.

A first aspect of the embodiments of the present application provides an electronic device, including a first housing, where the first housing is a metal part, the first housing includes a housing body and a friction surface, and the friction surface is formed on an outer surface of the housing body and forms a first touch area on the first housing; the part of the shell body exposed outside the friction surface forms a second touch area on the first shell; the first touch area is disposed near an edge of the first housing, and the first touch area and the second touch area have different surface roughness.

According to the embodiment of the application, the friction surface and the second touch area are arranged on the first shell, and the friction surface forms the first touch area on the first shell, so that an electronic device such as a notebook computer can simultaneously comprise the first touch area and the second touch area on the first shell. Due to the fact that the first touch area and the second touch area have different surface roughness, two different contact effects exist on the outer surface of the first shell of the electronic device, different friction forces can be provided for changing the configuration of the electronic device with one hand, and therefore the electronic device can be changed with one hand, and the electronic device, such as a notebook computer, can be opened and closed with one hand. In addition, because the friction surface is formed on the outer surface of the shell body, the friction surface can be formed in the preparation process of the first shell without post processing, and the same appearance effect can be realized when the first shell has different contact effects.

In one possible implementation, the surface roughness of the first touch area is greater than the surface roughness of the second touch area. Therefore, the surface roughness of the first shell can be locally increased through the first touch area, the electronic equipment is effectively prevented from being pushed to the rear when the electronic equipment is opened by one hand, and the electronic equipment is favorably changed by one hand.

In one possible implementation manner, the electronic device comprises a second shell, the first shell is movably connected with the second shell through a connecting portion, and the friction surface is located on one side, opposite to the connecting portion, of the first shell.

Therefore, the friction surface can be close to the user side of the electronic equipment, so that when a user uses one hand to change the configuration of the electronic equipment, for example, when the user uses one hand to open the electronic equipment, the user can effectively squeeze the first shell by placing fingers on the friction surface while buckling the display side of the electronic equipment, and the configuration of the electronic equipment can be changed by using one hand.

In one possible implementation, the friction surface is disposed adjacent to an opening and closing portion on a side wall of the second housing, and the opening and closing portion is located on a side of the second housing opposite to the connecting portion.

Through the arrangement of the opening and closing part, an effective squeezing area can be provided for fingers when a single-hand opening action is carried out. Meanwhile, the friction surface is close to the opening and closing part, so that the configuration of the electronic equipment can be changed conveniently by one hand.

In one possible implementation, the electronic device includes a display screen disposed on the first housing and opposite to the second housing. Therefore, the electronic device can be opened or closed by changing the position of the first shell relative to the second shell and further changing the configuration of the electronic device.

In a possible implementation manner, the area of the first touch area is smaller than the area of the second touch area, and at least part of the first touch area is wrapped by the second touch area. Therefore, the first shell is ensured to have different contact effects, so that the first shell has the touch change of local friction damping change, and meanwhile, the first touch area can be prevented from causing excessive influence on the touch or appearance of the first shell and the electronic device.

In one possible implementation manner, the first shell comprises a shell body, and the outer surface of the shell body is an oxidation layer with micropores;

the housing body comprises a first transparent hole sealing layer, the first transparent hole sealing layer is formed and filled with micropores, the first transparent hole sealing layer and the friction surface have different surface roughness, and the region of the first transparent hole sealing layer on the housing body forms a second touch region.

Therefore, the first shell can present the appearance of the metal anode through the arrangement of the oxide layer, and the surface of the first shell has metal luster. The pores can then be filled through the first transparent pore-sealing layer, so that the surface of the first shell is very smooth and the color of the first shell can be revealed, and the pores can be sealed to enhance the anti-pollution and anti-corrosion performance of the first shell. Because the first transparent hole sealing layer and the friction surface have different surface roughness, two different contact effects can be formed on the first shell, and the configuration of the electronic device can be changed by one hand.

In one possible implementation, the friction surface includes a masking portion that forms and fills the pores. By arranging the shielding part, the formation of the friction surface and the first touch area on the first shell can be facilitated, and meanwhile, the micropores in the first touch area can be sealed, so that the anti-pollution capacity and the anti-corrosion performance of the first shell are enhanced.

In one possible implementation, the surface of the shielding part is flush with the surface of the housing body, or the surface of the shielding part is higher than the surface of the housing body. In this way, while the friction surface and the first touch region are formed on the first housing, the configurations of the shielding portion and the first housing can be further diversified.

In a possible implementation manner, when the surface of the shielding part is higher than the surface of the shell body, two adjacent shielding parts are connected with each other and form a shielding layer covering the outer surface of the shell body.

This enhances the tactile feel variation of the local frictional damping variation on the first housing brought about by the friction face, so that the user can better perceive two different contact effects on the first housing.

In one possible implementation, the shielding portion is a transparent structure. Thus, the friction surface on the first shell is formed, and simultaneously, the color of the first shell can be exposed through the shielding part, so that the first shell and the electronic equipment have two different contact effects under one appearance.

In one possible implementation, the masking portion is formed by curing a transparent masking material that does not chemically react with the sealant forming the first transparent hole-sealing layer. In this way the obscuration and the first transparent aperture layer may be co-present within the first housing so as to present two different contact effects on the first housing.

In one possible implementation, the surface roughness of the masking portion is greater than the surface roughness of the first transparent aperture sealing layer. Therefore, two different surface roughnesses can be formed on the first shell, so that the first shell has different contact effects, the first shell has touch change with local friction damping becoming large, and the configuration of the electronic device can be changed by one hand conveniently.

In one possible implementation, the friction surface comprises a second transparent hole sealing layer, the second transparent hole sealing layer is formed and filled with micropores, and the second transparent hole sealing layer and the first transparent hole sealing layer have different surface roughness.

The second transparent hole sealing layer forms a friction surface and a first touch area, two different surface roughnesses can be formed on the first shell while the micropores are sealed through the first transparent hole sealing layer and the second transparent hole sealing layer, the configuration of the electronic equipment can be changed by one hand in the first touch area, and the coloring adhesive force of the first shell can be improved.

In one possible implementation, the surface roughness of the second transparent aperture-sealing layer is greater than the surface roughness of the first transparent aperture-sealing layer. Therefore, two different surface roughnesses can be formed on the first shell, so that the first shell has different contact effects, and the configuration of the electronic device can be changed by one hand.

In one possible embodiment, the friction surface comprises a plurality of pores exposed at the housing body. This restores a rougher tactile impression to the micro-porous surface on the first housing to provide two different surface roughnesses on the first housing that facilitate one-handed changing of the configuration of the electronic device in the first touch area.

In a possible implementation manner, the first shell further comprises a dyed layer filled in the micropores, and the dyed layer is located at the bottom layer of the micropores. Therefore, the decorative film layer with better color can be formed on the shell body through the dyeing layer, so that the appearance diversity and the aesthetic property of the first shell are enhanced.

A second aspect of the embodiments of the present application provides a manufacturing method of an electronic device, the manufacturing method being applied to any one of the electronic devices described above, the manufacturing method including:

carrying out surface treatment on a base material for preparing a first shell;

performing corrosion oxidation on the base material after the surface treatment to form an oxide layer with micropores on the surface of the base material;

dyeing the surface of the substrate to form a dyed layer in the micropores;

the edge area of the base material is partially shielded to form a shielding layer covering the base material, wherein the area where the shielding layer is located is a first touch area on the first shell;

and carrying out hole sealing treatment on the second touch area on the first shell once to obtain the first shell, wherein the area except the first touch area on the first shell is the second touch area, and the surface roughness of the first touch area is different from that of the second touch area.

According to the embodiment of the application, through the arrangement of the shielding layer, different surface roughness can be formed on the first shell in the preparation process of the first shell under the condition that the appearance consistency is not influenced, so that two different contact effects exist on the outer surface of the first shell of the electronic equipment, different friction forces can be provided for changing the configuration of the electronic equipment by one hand, and the electronic equipment can be changed by one hand, for example, the notebook computer can be opened and closed by one hand.

In a possible implementation manner, the edge region of the substrate is masked to form a masking layer covering the housing body, and the method specifically includes:

filling the micropores in the edge area of the base material with a shielding material, and forming shielding parts in the micropores;

and connecting the two adjacent shielding parts to form a shielding layer covering the shell body.

Therefore, the touch feeling change of the local friction damping change on the first shell brought by the first touch area can be enhanced, so that a user can better perceive two different contact effects on the first shell. At the same time, by filling the pores in the edge region of the substrate with a masking material, the masking layer can be positioned at the edge region of the substrate, thereby facilitating one-handed changing of the configuration of the electronic device.

In a possible implementation manner, after the base material is subjected to the hole sealing treatment for one time, before the first shell is obtained, the method further includes:

and removing the shielding layer to expose the micropores on the base material covered by the shielding layer.

This exposes the micro-pores on the substrate and restores a rougher feel to the surface of the micro-pores on the first shell to form two different surface roughnesses on the first shell.

removing the shielding layer;

and carrying out secondary hole sealing treatment on the area where the shielding layer on the base material is positioned, wherein the secondary hole sealing treatment adopts a hole sealing agent with different surface roughness from the primary hole sealing treatment.

Therefore, two different kinds of surface roughness can be formed on the first shell by selecting the hole sealing agents with different surface roughness, the configuration of the electronic equipment can be changed by one hand in the first touch area, and meanwhile, the coloring adhesive force of the first shell can be improved.

Detailed Description

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

At present, with the increasing popularity of electronic devices such as notebook computers, the functions and appearance effects of users on notebook computers are gradually improved. Generally, the casing of the notebook computer is mostly made of metal, such as aluminum or aluminum alloy. When the notebook computer adopts the metal shell prepared from aluminum or aluminum alloy and the like, the metal shell can have the appearance of the metal anode by matching with the treatment processes such as anodic oxidation and the like, the metal shell presents metal luster, and the touch feeling on the surface of the notebook computer can be very smooth while the metal shell makes exquisite appearance effect, so that the requirement of a user on the appearance effect of the notebook computer is met.

Nowadays, more and more users pay attention to whether the notebook computer has the experience of opening with one hand. Particularly, a business group is mainly used, and the business group often has a scene that one hand answers a phone and the other hand needs to start a notebook computer during working, so that the demand of the user group on starting the notebook computer by one hand is stronger.

However, with the trend of the notebook computer becoming lighter and thinner, it is difficult to provide enough friction force with the working table top of the notebook computer, such as the desktop, only by the soft rubber pad at the bottom of the notebook computer, and in addition, the casing of the notebook computer is mostly made of metal, and the surface is very smooth. Therefore, when the user performs the action of opening the notebook computer 100 with the fingers 200 with one hand as shown in fig. 1, since the surface of the notebook computer 100 is very smooth, the situation that the whole notebook computer 100 is pushed backward (i.e. the whole notebook computer slides backward) as shown by the arrow in fig. 2 often occurs, which not only causes the failure of opening with one hand, but also may cause the notebook computer to fall and damage at a small angle (e.g. 30 degrees or 20 degrees) and thus affect the user experience.

In view of the above, embodiments of the present application provide an electronic device and a method for manufacturing the same, in which a friction surface and a second touch area are disposed on a first housing of the electronic device, and the friction surface forms a first touch area on the first housing, so that the electronic device can simultaneously include the first touch area and the second touch area on the first housing. The first touch area and the second touch area are provided with different surface roughness, so that two different contact effects exist on the outer surface of the first shell of the electronic equipment, different friction forces can be provided for changing the configuration of the electronic equipment by one hand, and the configuration of the electronic equipment, such as the configuration of a notebook computer, can be changed by one hand. On the basis, as the friction surface is formed on the outer surface of the shell body of the first shell, the friction surface can be formed in the preparation process of the first shell, and the first shell has different contact effects and can contribute to realizing the same appearance effect of the electronic equipment.

In this embodiment, the electronic device may include, but is not limited to, a notebook computer, a mobile phone, a tablet computer, a handheld computer, an intercom, a POS machine, a wearable device, or other electronic devices with a gripping or damping surface requirement.

Examples

Fig. 3 is a schematic structural diagram of a notebook computer according to an embodiment of the present application, and fig. 4 and 5 are schematic diagrams of a process for opening the notebook computer with one hand according to the embodiment of the present application. Fig. 4 and 5 are schematic structural diagrams of the notebook computer in different states when the notebook computer is opened by one hand.

Fig. 3 to 5 show a structure of a notebook computer, and referring to fig. 3 to 5, in order to better describe the structure of the notebook computer, the notebook computer 100 is generally divided into an a-side, a B-side, a C-side and a D-side. The surfaces a, B, C and D respectively correspond to the top cover, the display screen, the keyboard 30 and the bottom case 22 of the notebook computer 100. The top cover of the side a, the frame 21 of the side B and the side C, and the bottom case 22 together form a casing of the notebook computer 100.

As can be seen from fig. 3 to 5, the electronic device, such as the notebook computer 100, may include a first housing 10, the first housing 10 is a metal member, the first housing 10 includes a housing body 11 and a friction surface, the friction surface is formed on an outer surface of the housing body 11 and constitutes a first touch area 12 on the first housing 10. That is, the area of the friction surface is the first touch area 12.

The part of the shell body 11 exposed outside the friction surface forms a second touch area 13 on the first shell 10; the first touch area 12 is disposed near an edge of the first casing 10, and the first touch area 12 and the second touch area 13 have different surface roughness.

Thus, compared to the existing notebook computer, the electronic device, such as the notebook computer 100, of the embodiment of the present application may include both the first touch area 12 and the second touch area 13 on the first casing 10. Since the first touch area 12 and the second touch area 13 have different surface roughness, the electronic device has two different contact effects on the outer surface of the first casing 10, and the touch feeling of the local frictional damping change changes accordingly. Therefore, when the finger 200 is in contact with the first touch area 12 or the second touch area 13, the first touch area 12 and the second touch area 13 can provide different friction forces for changing the configuration of the electronic device with one hand, so as to realize changing the configuration of the electronic device with one hand, for example, opening the notebook computer 100 with one hand, to better meet the requirement of a business group on opening the notebook computer 100 with one hand, and enhance the experience of a user.

In addition to this, since the friction surface is formed on the outer surface of the housing body 11, it is possible to form the friction surface during the preparation of the first housing 10. That is, the friction surface is formed during the preparation of the first housing 10 without post-processing. This may help to achieve the same appearance effect of the electronic device while the first housing 10 has different contact effects.

It is understood that, as shown in fig. 2 and 3, the first touch area 12 is disposed near the edge of the first casing 10 in the embodiment of the present application, so that when a single hand contacts the first touch area 12, the first casing 10 can be opened from the edge of the first casing 10, and the configuration of the electronic device can be changed by changing the position of the first casing 10 relative to other casings of the electronic device, such as the notebook computer 100, thereby facilitating the single-hand opening of the notebook computer 100 and the like.

It should be noted that, in the embodiment of the present application, by providing the first touch area 12 and the second touch area 13 on the first casing 10, the present application is not only applicable to an application scenario of one-handed opening of the notebook computer 100 and the like, but also applicable to other application scenarios, for example, a scenario that the electronic device needs to be held by one hand, such as a mobile phone and the like, or a scenario that surface friction damping of other electronic devices, such as a mobile phone or a handheld computer, has a changing requirement, so as to increase a risk of falling prevention of the electronic device and the like.

The first casing 10 may be understood as a top cover of the a-side of the notebook computer 100. Thus, different contact effects can be formed on the top cover, so that a single hand can contact and press the first touch area 12 or the second touch area 13 of the top cover to open the top cover, and the notebook computer 100 is changed from the closed state shown in fig. 4 to the open state shown in fig. 5, thereby changing the configuration of the notebook computer 100 and realizing the one-hand opening of the notebook computer 100 and the like.

Exemplary metal articles include, but are not limited to, metal structures made of metal materials such as aluminum, aluminum alloys, titanium or titanium alloys that can be anodized.

As can be seen from fig. 3 to 5, the electronic device, such as the notebook computer 100, may further include a second housing 20, and the first housing 10 is movably connected to the second housing 20 through a connecting portion. The first housing 10 is thus movable relative to the second housing 20 such that the first housing 10 can be positionally varied relative to the second housing 20 to facilitate changing the configuration of the electronic device.

Wherein, the movable connection includes but not limited to a rotation connection or a sliding connection. This makes it possible to make the connection manner of the first casing 10 and the second casing 20 more diversified.

When the first casing 10 is rotatably connected to the second casing 20 through the connecting portion, the first casing 10 can be moved relative to the second casing 20 by a rotating manner, thereby changing the configuration of the electronic device.

Illustratively, the connecting portion includes, but is not limited to, a rotating shaft. The first casing 10 and the second casing 20 can be rotatably connected by a rotating shaft, so that the first casing 10 rotates relative to the second casing 20 around the rotating shaft under the action of external force, thereby changing the configuration of the electronic device.

The second casing 20 can be understood as a frame 21 and a bottom casing 22 of the C-side of the notebook computer 100. That is, the frame 21 and the bottom case 22 of the C-side constitute the second casing 20 of the notebook computer 100.

Specifically, the electronic device, such as the notebook computer 100, may further include a display screen, which is disposed on the first casing 10 and is opposite to the second casing 20. That is, the first casing 10 is located at a side of the electronic device having the display screen. This allows the electronic device to be opened or closed by changing the position of the first housing 10 relative to the second housing 20, and thus the configuration of the electronic device, such that the display screen is in an open or closed position.

It is to be understood that the illustrated structure of the embodiment of the present application does not specifically limit the notebook computer 100. In other embodiments of the present application, the notebook computer 100 may also include more or fewer components than shown, or some components may be combined, some components may be separated, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

To facilitate one-handed opening of an electronic device such as a notebook computer 100, the friction surface may be located on a side of the first housing 10 opposite to the connecting portion as shown in fig. 3 to 5. That is, the friction surface is disposed proximate to the front end of the electronic device. Therefore, the friction surface can be close to the user side 16 of the electronic device, which is in accordance with the operation habit of the user, so that the user can change the configuration of the electronic device with one hand, for example, when performing a single-hand opening action, as shown in fig. 4, the user can use the thumb to buckle the display side of the electronic device, and at the same time, the user can place the rest fingers 200 on the friction surface, and effectively squeeze the first housing 10 by using the friction force between the fingers 200 and the friction surface, which can greatly reduce the possibility that the whole notebook computer 100 slides backwards when the notebook computer 100 is opened with one hand, so that the position of the first housing 10 relative to the second housing 20 is changed under the combined action of the thumb, thereby realizing the configuration change of the electronic device with one hand, for example, realizing the single-hand opening of the notebook computer 100 as shown in fig. 5. The display side of the electronic device may be understood as a side of the electronic device, such as the notebook computer 100, having the display screen.

As a possible embodiment, referring to fig. 3 to 5, the friction surface may be provided near an opening and closing portion 23 on a side wall of the second housing 20, the opening and closing portion 23 being located on a side of the second housing 20 opposite to the connecting portion. That is, the opening and closing part 23 is located at the front end or user side 16 of the electronic device. By providing the opening/closing portion 23, an effective pressing area can be provided for the finger 200 such as a thumb when performing a one-handed opening operation, so that the display side of the electronic apparatus can be closed with the thumb. Meanwhile, since the friction surface is disposed close to the opening/closing portion 23, the finger 200 can simultaneously act on the opening/closing portion 23 and the friction surface, and the configuration of the electronic device can be changed by one hand.

Illustratively, the opening and closing portion 23 includes, but is not limited to, a groove on a sidewall of the second housing 20. This can expose a part of the edge of the first casing 10, so that the display side of the electronic device can be buckled while the finger 200 is squeezed in the groove to the second casing 20, which helps to realize the configuration change of the electronic device with one hand.

Fig. 6 is a schematic structural diagram of another notebook computer provided in the embodiment of the present application, and fig. 7 is a schematic structural diagram of another notebook computer provided in the embodiment of the present application.

As shown in fig. 3 to 7, the frictional surface may be provided to face the opening/closing portion 23. This facilitates the finger 200 to act on the opening/closing portion 23 and the frictional surface at the same time. The friction face may be located in the middle of the user side 16 of the first housing 10 as shown in figures 3 to 5. Alternatively, the friction face may be located at the right end of the user side 16 of the first housing 10 as shown in fig. 6. Alternatively, the friction face may be located at the left end of the user side 16 of the first housing 10 as shown in figure 7. In the present embodiment, the position of the friction surface on the first housing 10 is not further limited.

As another possible embodiment, the friction surface may be located at a side of the edge of the first housing 10 (i.e., at a right side or a left side of the notebook computer 100 shown in fig. 7). This may locally increase the friction of the first housing 10, increasing the risk of falling of the notebook computer 100.

The electronic device in the embodiment of the present application will be further explained below by taking the first touch area 12 as an example located in the middle of the user side 16 of the first housing 10.

As a possible implementation, as shown in fig. 3 to 7, the area of the first touch area 12 is smaller than the area of the second touch area 13, and at least a part of the first touch area 12 is surrounded by the second touch area 13. Thus, while ensuring that the first casing 10 has different contact effects, so that the first casing 10 has a touch change with a local friction damping change, the area occupied by the first touch region 12 on the first casing 10 can be made smaller, so that most of the surface of the first casing 10 is still smooth, and thus the first touch region 12 is prevented from having an excessive influence on the touch or appearance of the first casing 10 and the electronic device.

It should be noted that the second touch area 13 may be an area with a smooth surface after being anodized or processed by other processes such as electrophoresis.

Wherein the first touch area 12 and the second touch area 13 constitute the outer surface of the first housing 10. At least a part of the first touch area 12 is surrounded by the second touch area 13, that is, the first touch area 12 may be completely surrounded by the second touch area 13 as shown in fig. 3 to 7, or the first touch area 12 may be provided at an outermost edge of the first housing 10 such that a part of the first touch area 12 is surrounded by the second touch area 13. In the present embodiment, the position and size of the first touch area 12 are not further limited.

As a possible embodiment, the surface roughness of the first touch area 12 is greater than the surface roughness of the second touch area 13. Thus, the surface roughness of the first casing 10 can be locally increased through the first touch area 12, an area with a larger friction force is provided on the first casing 10, a better force application point can be provided for the finger 200, the friction force between the finger 200 and the first casing 10 is increased, so that the finger 200 can effectively squeeze the first casing 10, the possibility that the electronic device such as the notebook computer 100 integrally slides backwards when the single-hand opening action is performed is effectively reduced, and the change of the configuration of the electronic device, such as the single-hand opening of the notebook computer 100, is facilitated.

Alternatively, the surface roughness of the first touch area 12 may be smaller than the surface roughness of the second touch area 13.

The electronic device in the embodiment of the present application will be further described below by taking as an example that the surface roughness of the first touch area 12 is greater than the surface roughness of the second touch area 13.

Fig. 8 is a microscopic view of the first housing of the notebook computer in fig. 3 taken along a-a direction, fig. 9 is an enlarged view of the first housing of the notebook computer in fig. 8 at a portion B, fig. 10 is another enlarged view of the first housing of fig. 9 at a portion B provided in an embodiment of the present application, and fig. 11 is another microscopic view of the first housing of fig. 9 at a portion B provided in an embodiment of the present application.

Referring to fig. 8 to 11, the first case 10 may include a case body 11, and an outer surface of the case body 11 is an oxide layer having micro holes 111. Through the arrangement of the oxide layer, the first shell 10 can present a metal anode appearance, and the surface has a metal luster, so that the first shell 10 can make a delicate appearance effect to meet the requirement of a user on the appearance of the electronic device.

The oxide layer having the micropores 111 may be formed on the surface of the base material 114 of the case body 11 by performing an anodic oxidation process on the base material 114 of the case body 11.

Specifically, the housing body 11 includes a first transparent hole sealing layer 113, the first transparent hole sealing layer 113 is formed to fill the micro holes 111, the first transparent hole sealing layer 113 and the friction surface have different surface roughness, and a region of the first transparent hole sealing layer 113 on the housing body 11 constitutes the second touch region 13. Thus, the first transparent hole sealing layer 113 fills up the micro holes 111, on one hand, the surface of the first casing 10 in the second touch area 13 is very smooth, and at the same time, the color of the first casing 10 can be exposed due to the transparent property of the first transparent hole sealing layer 113; on the other hand, the micro-holes 111 can be closed by the first transparent hole-sealing layer 113 to enhance the anti-contamination capability and the anti-corrosion performance of the first casing 10 and the electronic device.

Meanwhile, since the first transparent capping layer 113 and the friction surface have different surface roughness, that is, the first touch region 12 and the second touch region 13 have different surface roughness. This enables two different contact effects to be formed on the first housing 10, which facilitates a one-handed configuration change of the electronic device, such as a one-handed opening of the notebook computer 100.

It should be noted that the first transparent hole sealing layer 113 is formed by curing the sealant filled in the micro holes 111.

Illustratively, the pore depth of the micropores 111 includes, but is not limited to, 5um to 20um, and the like. This facilitates the formation of the first transparent aperture sealing layer 113 and the rubbing face without affecting the strength of the first housing 10. In practical applications, the depth of the micro-hole 111 may be adjusted according to the type of the electronic device and the thickness of the whole device. In the present embodiment, the hole depth of the micro-hole 111 is not further limited.

Further, referring to fig. 8 to 11, the first housing 10 further includes a dye layer 112 filled in the micro-holes 111, and the dye layer 112 is located at a bottom layer of the micro-holes 111. Since fig. 8 to 11 are structural diagrams of the first housing 10 in a microscopic state, the first housing 10 is dyed by the arrangement of the dyed layer 112 in the micro-holes 111, so that the housing body 11 has a decorative film layer with better color, so as to enhance the variety and the aesthetic property of the appearance of the first housing 10, and the appearance of the first housing 10 and the electronic device is more personalized and refined, so as to better meet the requirement of a user for the appearance of the electronic device.

The dye layer 112 is formed by curing a dye filled in the bottom of the micro-hole 111. To facilitate the formation of the first transparent aperture-sealing layer 113 and the rubbing face, the dye layer 112 does not fill the depth of the pores 111.

As a possible embodiment, referring to fig. 8 to 10, the friction surface may include a shielding portion 14 therein, and the shielding portion 14 forms and fills the micro-holes 111. That is, the shielding portion 14 forms a friction surface of the first housing 10. By the arrangement of the shielding portion 14, not only the shielding layer 15 can form a friction surface on the first casing 10 and the first touch area 12, which is helpful for realizing different surface roughness on the first casing 10 under the same appearance effect, and is convenient for changing the configuration of the electronic device with one hand, but also the micropores 111 in the first touch area 12 can be sealed to enhance the anti-pollution capability and the anti-corrosion capability of the first casing 10.

Illustratively, the shielding portion 14 may be a transparent structure. In this way, while the formation of the friction surface on the first housing 10 is ensured, the color of the first housing 10 (i.e., the color of the dyed layer 112) can be revealed through the shielding part 14, so that the first housing 10 and the electronic device have two different surface roughnesses under the same appearance.

The shielding portion 14 may be formed by curing a transparent shielding material, and the shielding material does not chemically react with the sealant forming the first transparent hole sealing layer 113. Thus, during the process of forming the first transparent hole sealing layer 113, the hole sealing agent cannot chemically react with the shielding material, so that the shielding portion 14 and the first transparent hole sealing layer 113 can coexist in the first housing 10 to present two different contact effects on the first housing 10.

Illustratively, the masking material may be an organic paint. The organic coating may include paint or ink, among others. The paint includes, but is not limited to, existing paint containing polyvinyl alcohol or polyvinyl acetate, and the ink includes, but is not limited to, existing alcohol-soluble ink containing polyvinyl alcohol or polyvinyl acetate. Accordingly, the sealant constituting the first transparent hole sealing layer 113 includes, but is not limited to, conventional sealant including nickel acetate and sodium fluoride. In the present embodiment, the kind of the masking material and the sealant constituting the first transparent hole sealing layer 113 are not further limited as long as both do not chemically react.

As a possible embodiment, the surface roughness of the shielding portion 14 may be greater than the surface roughness of the first transparent aperture sealing layer 113. This makes it possible to make the first casing 10 have a surface roughness with a large frictional force on the frictional surface, so that the first casing 10 has a tactile sensation variation with a large local frictional damping, so as to facilitate a one-handed change in the configuration of the electronic apparatus.

Alternatively, the surface roughness of the shielding portion 14 may be larger than the surface roughness of the first transparent hole sealing layer 113. In the present embodiment, the surface roughness of the shielding portion 14 and the surface roughness of the friction surface are not further limited.

Here, as shown in fig. 8 and 9, the surface of the shielding portion 14 may be higher than the surface of the housing body 11, or, as shown in fig. 10, the surface of the shielding portion 14 may be flush with the surface of the housing body 11. This makes it possible to diversify the structures of the shielding portion 14 and the first casing 10 while ensuring that the shielding portion 14 can form the friction surface and the first touch region 12 on the first casing 10.

Referring to fig. 8 and 9, when the surface of the shielding part 14 is higher than the surface of the housing body 11, adjacent two shielding parts 14 may be connected to each other and form a shielding layer 15 covering the outer surface of the housing body 11. This enables the scattered shielding portions 14 to be connected to each other and form the shielding layer 15, so as to enhance the tactile sensation variation of the local frictional damping variation on the first housing 10 caused by the friction surface, so that the user can better perceive two different contact effects on the first housing 10, and at the same time, can enable the finger 200 to be better pressed on the first housing 10, which is more beneficial to realize the configuration change of the electronic device with one hand.

The surface of the shielding portion 14 shown in fig. 8 and 9 is higher than the surface of the housing body 11, and the structure of the shielding portion 14 is described in detail. In practice, the height of the shielding portion 14 from the surface of the housing body 11 is not visible to the naked eye, which does not affect the appearance of the first housing 10 while facilitating one-handed configuration change of the electronic device. In the present embodiment, the height of the shielding portion 14 is not further limited.

As another possible embodiment, the masking portion 14 in fig. 10 may be replaced by another structure such as a second transparent capping layer. That is, the rubbing surface may include a second transparent hole sealing layer formed to fill the micro holes 111, the second transparent hole sealing layer and the first transparent hole sealing layer 113 having different surface roughness. Thus, the second transparent hole sealing layer can form a friction surface on the first casing 10 and the first touch area 12, two different surface roughnesses can be formed on the first casing 10 through the second transparent hole sealing layer and the first transparent hole sealing layer 113, further touch effect adjustment of damping feeling of the outer surface of the first casing 10 is achieved through different hole sealing agents, configuration of electronic equipment can be changed by one hand in the first touch area 12, meanwhile, micropores 111 in the friction surface can be sealed, and therefore pollution resistance and corrosion resistance of the first casing 10 and the electronic equipment are improved. Meanwhile, compared with the shielding part 14, the second transparent hole sealing layer can provide more reliable coloring adhesion force for the coloring layer 112, thereby improving the coloring adhesion force of the first housing 10.

As a possible embodiment, the surface roughness of the second transparent aperture-sealing layer may be greater than the surface roughness of the first transparent aperture-sealing layer 113. This allows two different surface roughnesses to be formed on the first housing 10, so that the first housing 10 has different contact effects, facilitating a one-handed change of the configuration of the electronic device.

Alternatively, the surface roughness of the second transparent hole-sealing layer may be smaller than the surface roughness of the first transparent hole-sealing layer 113, and in this embodiment, the relationship between the surface roughness of the second transparent hole-sealing layer and the surface roughness of the first transparent hole-sealing layer 113 is not further limited.

As a possible embodiment, as shown in fig. 11, the friction surface may further include a plurality of micro holes 111 exposed on the housing body 11. This restores a rougher feel to the surface of the micro-holes 111 in the first housing 10 in the friction plane to provide two different surface roughnesses in the first housing 10 to facilitate one-handed changing of the configuration of the electronic device in the first touch area 12.

Fig. 12 is a schematic flow chart of a method for manufacturing an electronic device according to an embodiment of the present disclosure, and fig. 13 to 17 are microscopic representations of a substrate for preparing a first housing at different stages.

On the basis of the above, referring to fig. 12 in combination with fig. 13 to 17, an embodiment of the present application further provides a manufacturing method of an electronic device, which can be applied to the above electronic device, and the manufacturing method includes:

step S01: and carrying out surface treatment on the substrate for preparing the first shell.

The surface treatment of the substrate 114 may be degreasing, polishing, neutralization, cleaning, and the like in this order, so that dust, grease, and the like on the surface of the substrate 114 can be removed, the surface of the substrate 114 is smooth, the metal color of the substrate 114 itself is exhibited, and the treatment liquid remaining on the substrate 114 during the surface treatment can be removed. A microscopic view of the surface-treated substrate 114 can be shown in fig. 13.

The base material 114 includes, but is not limited to, a metal base material made of a metal material such as aluminum, an aluminum alloy, titanium, or a titanium alloy. The degreasing, polishing, neutralizing, cleaning, and the like are conventional surface treatment processes performed on the metal substrate 114, and in this embodiment, no further description is provided for the surface treatment performed on the substrate 114.

Step S02: and etching and oxidizing the surface-treated base material to form an oxide layer with micropores on the surface of the base material.

It should be noted that, the corrosion oxidation refers to subjecting the surface-treated base material 114 to corrosion in an acidic or alkaline solution and performing conventional anodic oxidation, and controlling anodic oxidation conditions, such as voltage, anodic current density, anodic oxidation time, and the like, to form an oxide layer with micropores 111 on the surface of the base material 114, so that the surface of the base material 114 presents a metal anode appearance, and the surface has a metallic luster, so as to make a delicate appearance effect on the base material 114 and the first housing 10, and at the same time, enhance the corrosion resistance of the base material 114 and the first housing 10. A microscopic view of the substrate 114 after the etching oxidation treatment can be seen in fig. 14.

The composition of the oxide layer depends on the material of the substrate 114, for example, when the substrate 114 is an aluminum material, the oxide layer may be an aluminum oxide film. Therefore, in this embodiment, the composition of the oxide layer is not further limited. The etching oxidation is a corresponding flow in the conventional anodic oxidation process, and in this embodiment, the specific flow of the etching oxidation is not further described.

Step S03: the surface of the substrate is dyed to form a dyed layer within the microwells.

It should be noted that, due to the existence of the micropores 111 in the oxide layer, the oxide layer has a relatively large porosity and an adsorption force, so that when the surface of the substrate 114 is dyed, since the micropores 111 in the oxide layer are in a microscopic state and the arrangement of the micropores 111 in the oxide layer is very close, the dyeing of the substrate 114 can be realized while the dye is adsorbed in the micropores 111 in the oxide layer, so as to form a decorative film layer with a good color on the surface of the substrate 114 and the first housing 10.

Referring to fig. 15, the dye layer 112 is not filled in the micro-holes 111 and is located at the bottom of the micro-holes 111. This allows the sealant to continue to fill the pores 111 to form the first transparent pore sealing layer 113, and also facilitates formation of the rubbing surface on the first housing 10.

It should be noted that, reference may be made to the above description of the dye layer 112 and the microwell 111 for the formation of the dye layer 112 and the depth of the microwell 111, and in this embodiment, further description is not repeated for the formation of the dye layer 112 and the depth of the microwell 111.

Step S04: and partially shielding the edge area of the substrate to form a shielding layer covering the substrate, wherein the area where the shielding layer is located is a first touch area on the first shell.

In step S04, the step of masking the edge area of the substrate to form a masking layer covering the substrate specifically includes:

filling the pores 111 in the edge region of the substrate 114 with a masking material and forming the masking portions 14 in the pores 111;

the adjacent two shielding portions 14 are connected to each other to form a shielding layer 15 covering the substrate 114, and the specific structure is shown in fig. 16 and 17.

By arranging the shielding layer 15, a friction surface can be formed on the first casing 10 during the manufacturing process of the first casing 10 without affecting the consistency of the appearance, and the first touch area 12 is defined by the friction surface, which facilitates the formation of different surface roughness and touch areas on the first casing 10, thereby facilitating the configuration change of the electronic device, such as the one-handed opening and closing of the notebook computer 100, with one hand. At the same time, the touch feeling change of the local friction damping change on the first casing 10 brought by the first touch area 12 can be enhanced by the shielding layer 15, so that the user can better perceive two different contact effects on the first casing 10.

It should be noted that, according to the preset position of the friction surface and the first touch area 12 on the first casing 10, the edge area of the substrate 114 may be partially shielded at the position corresponding to the preset position, and the structure of the shielded substrate 114 may be as shown in fig. 16 and 17. The shielding layer 15 may be formed by forming a shielding material such as an organic paint on the edge region of the substrate 114 by printing or the like, and then curing the material.

In this embodiment, reference may be made to the above description of the shielding layer 15, and in this embodiment, further description is not given to the formation of the shielding layer 15 and the hole depth of the micro-hole 111.

S05: and carrying out hole sealing treatment on the second touch area on the first shell once to obtain the first shell, wherein the area except the first touch area on the first shell is the second touch area, and the surface roughness of the first touch area is different from that of the second touch area.

It should be noted that the one-time sealing treatment may be understood that the micropores 111 in the second touch region 13 are filled with the sealing agent, and then the sealing agent is subjected to a curing treatment (such as heating or light irradiation) so that the micropores 111 in the second touch region 13 can be filled with the first transparent sealing layer 113.

The structure of the first housing 10 obtained is as shown in fig. 8 to 11. The obtained surface of the first casing 10 presents an anode appearance made of a metal material, and has a metallic luster, and a decorative film layer with a good color can be formed on the surface of the first casing 10, so as to meet the requirements of users on the appearances of the first casing 10 and the electronic device.

In order to form two different surface roughnesses on the first casing 10, as another possible embodiment, after the base material is subjected to the sealing treatment once and before the first casing is obtained, the method may further include:

the masking layer 15 is removed to expose the micro-holes 111 on the substrate 114 covered by the masking layer 15. This exposes the micro-holes 111 on the base material 114 and restores a rougher tactile sensation to the surface of the micro-holes 111 on the first housing 10, and the exposed micro-holes 111 form a rubbing surface as shown in fig. 11, so that two kinds of touch areas having different surface roughness are formed on the first housing 10.

It should be understood that in the embodiment of the present application, the masking layer 15 may be removed by chemically reacting the masking layer dissolving agent with the masking material in the masking layer 15 to etch the masking layer 15. The type of the dissolving agent for the shielding layer 15 depends on the shielding material used for the shielding layer 15, and in this embodiment, the type of the dissolving agent for the shielding layer 15 is not further limited.

Alternatively, after the base material is subjected to the first sealing treatment and before the first housing is obtained, the method may further include:

removing the shielding layer 15;

and (3) carrying out secondary hole sealing treatment on the area where the shielding layer 15 is positioned on the substrate 114, wherein the secondary hole sealing treatment adopts a hole sealing agent with different surface roughness from the primary hole sealing treatment.

Note that, the area where the shielding layer 15 is located, that is, the first touch area 12, is subjected to a secondary sealing treatment, so that the micropores 111 located in the first touch area 12 are filled with the second transparent sealing layer and formed therein. The embodiment of the application can form the transparent hole sealing layer with two different surface roughnesses on the first shell 10 by selecting the hole sealing agents with different surface roughnesses in the primary hole sealing treatment and the secondary hole sealing treatment, and the coloring adhesive force of the first shell 10 can be improved while the configuration of the electronic equipment is changed by one hand in the first touch area 12.

In the embodiment of the present application, two different surface roughnesses may be formed on the first housing 10 in other manners. In the present embodiment, the structure of the first housing 10 in the friction surface is not further limited.

It should be understood that the manufacturing method in the embodiment of the present application is mainly directed to the preparation of the first casing 10 of the electronic device, and the manufacturing method of the rest of the electronic device may refer to the corresponding prior art, and will not be further described in this embodiment.

In the embodiment of the present application, the friction surface is disposed on the first casing 10, and the friction surface forms the first touch area 12 on the first casing 10, so that the electronic device can simultaneously include the first touch area 12 and the second touch area 13 with different surface roughnesses on the first casing 10, so that two different contact effects exist on the external surface of the first casing 10 of the electronic device, which is beneficial to changing the configuration of the electronic device, such as opening and closing the notebook computer 100 with one hand.
