Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of appearance structure, and in particular to an appearance structure and an electronic stylus. BACKGROUND

[0002] The appearance structure of many consumer products needs to be partially light-transmissive and other areas need to be non-light-transmissive. For example, the cap (or tail) of some electronic styluses is provided with a light strip. When the light source inside the pen barrel emits light, the light is transmitted from the light strip of the cap, and other areas are non-light-transmissive, thereby presenting the appearance effect of the cap partially emitting light. At present, there are mainly two methods to achieve this effect:

[0003] 1. A light hole is formed on the appearance structure, and a light guide structure is used to guide the light of the light source to the light hole, and the light is emitted from the light hole. This scheme needs to form a hole on the appearance structure, and there is a clear appearance step difference between the hole and other parts, which destroys the consistency of the appearance.

[0004] 2. A light-transmissive material is used to manufacture the base body of the appearance structure, and then non-light-transmissive paint is sprayed on the surface of the base body. Then, the non-light-transmissive paint of the area (such as the light strip) that needs to emit light is removed by laser engraving process, and finally the transparent color paint is sprayed on the surface after laser engraving, so that the appearance structure presents a specific color. The current non-light-transmissive paint is relatively thick, about 20 um, which can easily cause uneven spraying of the transparent color paint, uneven surface, and uneven surface of the appearance structure, resulting in a clear appearance step difference between the light-transmissive area and the non-light-transmissive area, and poor appearance effect.

[0005] It can be seen that the appearance step difference between the light-transmissive area and the non-light-transmissive area of the appearance structure that is partially light-transmissive in the prior art is obvious, which destroys the consistency and beauty of the appearance, and the appearance effect is poor. CONTENT OF THE UTILITY MODEL

[0006] The appearance structure and the electronic stylus provided by the embodiments of the present application solve the problem of the appearance step difference between the light-transmissive area and the non-light-transmissive area of the appearance structure that is partially light-transmissive in the prior art, which destroys the consistency and beauty of the appearance, and the appearance effect is poor.

[0007] The first aspect of the embodiments of the present application provides an appearance structure, which comprises a base body and a film layer. The base body is a light-transmissive structure, and the outer surface of the base body comprises a first part and a second part arranged in connection. The film layer is arranged on the first part and the second part.

[0008] The film layer includes a light-blocking layer and a light-transmitting layer. The light-blocking layer is a film-coated structure and is arranged on the first part of the outer surface, and the light-blocking layer is a non-light-transmitting structure. The light-transmitting layer is arranged on the second part of the outer surface and the surface of the light-blocking layer away from the base, the light-transmitting layer has a color and is a light-transmitting structure. The thickness of the light-blocking layer is less than 10 μm.

[0009] The appearance structure provided in the embodiments of the present application includes a base and a film layer. The base is a light-transmitting structure and can allow light to pass through. The outer surface of the base has a first part and a second part, and the film layer is arranged on the first part and the second part. When the appearance structure is used as part of the appearance of an electronic product, the film layer arranged on the first part and the second part can be exposed and used as part of the appearance of the product, thereby protecting the base and presenting a specific appearance effect.

[0010] The film layer includes a light-blocking layer and a light-transmitting layer. The light-blocking layer is a non-light-transmitting structure and can block light. The light-transmitting layer can not only transmit light but also show a variety of colors, so that the entire outer surface presents a designed color effect. The light-blocking layer only covers the first part of the outer surface, and the second part can still transmit light. It can be understood that the second part is a light-transmitting region of the outer surface, and the first part is a non-light-transmitting region, so that the appearance structure can realize the effect of transmitting light in a local region. The light-transmitting layer covers the light-blocking layer and the second part of the outer surface. It can be understood that the light-transmitting layer covers the light-transmitting region and the non-light-transmitting region of the outer surface at the same time.

[0011] Further, the light-blocking layer is a film-coated structure, and the thickness of the light-blocking layer is less than 10 μm. The film-coated structure is a film layer structure formed by processes such as electroplating. When the thickness is relatively thin, the height difference between the region (the first part) on the first surface where the light-blocking layer is arranged and the region (the second part) where the light-blocking layer is not arranged is small. When the light-transmitting color paint is sprayed, the gully to be filled by the light-transmitting color paint is shallow. Therefore, the light-transmitting color paint can achieve similar or even equivalent covering power on the light-blocking layer and the second part of the outer surface. The surface of the light-transmitting color paint is relatively uniform, the appearance difference between the light-transmitting region and the non-light-transmitting region of the appearance structure is small, the consistency is strong, and the whole is relatively beautiful.

[0012] Therefore, the appearance structure provided in the embodiments of the present application has a small appearance difference between the light-transmitting region and the non-light-transmitting region, a good overall appearance effect, strong consistency, and is relatively beautiful.

[0013] In a possible implementation, the thickness of the light-blocking layer is in the range of 2 μm to 5 μm. In this range, the thickness of the light-blocking layer is thin enough and has a good light-blocking effect.

[0014] In a possible implementation, the material of the light-blocking layer is metal or alloy. Metal and alloy can be easily prepared by methods such as electroplating and form a film layer with a thickness meeting the requirements.

[0015] In a possible implementation, the material of the light-shielding layer is silver. The silver plating layer has strong metallic luster, high-end appearance, good process repeatability, is suitable for mass production, and can ensure the stability and consistency of product quality. In addition, the metallic and alloy materials have strong luster, which can increase the texture of the appearance structure.

[0016] In a possible implementation, the color of the light-shielding layer is black, and the color of the light-transmitting layer is white. The light-shielding layer is set to black, which can prevent the light-shielding area of the appearance structure from leaking light, and the light effect is better. The light-transmitting layer is set to white, which has good light-transmitting effect, and can make the outer surface of the appearance structure have an integrated white appearance, which is simple and atmospheric and not easy to get tired of.

[0017] In a possible implementation, the thickness of the part of the light-transmitting layer covering the light-shielding layer is in the range of 35 μm to 45 μm.

[0018] By using the above scheme, the light-transmitting layer not only completely compensates for the height difference between the second part of the outer surface and the light-shielding layer, but also has a smooth and uniform surface and strong covering capacity, preventing the outer surface and the covering layer from transmitting light, so that the appearance gap between the light-transmitting area and the light-shielding area is further reduced.

[0019] In a possible implementation, the light-transmitting layer includes a first layer and a second layer which are stacked, the first layer covers the second part of the outer surface and the surface of the light-shielding layer away from the base, and the second layer covers the surface of the first layer away from the light-shielding layer.

[0020] By using the above scheme, the light-transmitting layer is divided into two layers, and the two layers can be sprayed separately. First, the first layer is sprayed to compensate for the height difference between the second part of the outer surface and the light-shielding layer, and to preliminarily cover the light-shielding layer and the second part of the outer surface. Then, the second layer is sprayed to make the surface of the light-transmitting layer more uniform, achieving better spraying effect.

[0021] In a possible implementation, the thickness of the part of the first layer covering the light-shielding layer is in the range of 18 μm to 22 μm, and the thickness of the second layer is in the range of 18 μm to 22 μm. By controlling the thickness of the two layers to be in the range of 18 μm to 22 μm, the spraying surface can be more uniform.

[0022] In a possible implementation, the film layer further includes a protective layer, the protective layer is set to a light-transmitting structure, and covers the surface of the light-transmitting layer away from the base. The protective layer can protect the surface of the light-transmitting layer, prevent color loss, and provide good skin-friendly touch, improving touch comfort.

[0023] In a possible implementation manner, the light shielding layer is prepared by vacuum plating or non-conductive vacuum plating. The film structure prepared by vacuum plating or non-conductive vacuum plating is generally thin, generally micron level, and the total thickness can be less than 10 microns.

[0024] In a possible implementation manner, the second part of the outer surface is annular, and the light of the light source can light up the light ring when the light of the light source passes through the outer surface.

[0025] In a possible implementation manner, the appearance structure is a cap of an electronic stylus. The cap not only meets the requirements of local light transmission and appearance integration color, but also has no obvious step difference between the light transmission area and the non-light transmission area.

[0026] A second aspect of the embodiment of the present application provides an electronic stylus comprising the appearance structure provided by any of the implementation manners.

[0027] The appearance structure is used as a part of the appearance of the electronic stylus, the local light transmission of the shell of the electronic stylus is realized, and when the internal light source of the stylus does not emit light, the appearance of the stylus is highly consistent as a whole, and the appearance step difference between the light transmission area and the non-light transmission area is small.

[0028] In a possible implementation manner, the electronic stylus comprises a pen barrel and a cap arranged at one end of the pen barrel. When the appearance structure is the cap, a light source is arranged in the pen barrel, and light emitted by the light source passes through the second part of the outer surface of the cap and then passes out of the pen barrel.

[0029] By using the above scheme, the second part of the outer surface corresponds to the light transmission area of the cap, and the other part is the non-light transmission area. The light emitted by the light source only passes out of the light transmission area, and the other area is not light transmission. The effect of local light transmission of the cap is realized. In addition, by designing the first part and the second part of the outer surface into various shapes, various light effects can also be realized.

[0030] In a possible implementation manner, a light guide structure is further arranged in the pen barrel. The light guide structure is a light transmission structure. In the length direction of the pen barrel, the light guide structure has a first end face and a second end face opposite to each other. The first end face of the light guide structure is arranged opposite to the light source, and the second end face of the light guide structure is arranged opposite to the cap.

[0031] By using the above scheme, the light guide structure can transmit light, and the two end faces of the light guide structure are arranged opposite to the light source and the cap respectively, so that the light emitted by the light source can be more concentratedly transmitted to the cap.

[0032] In a possible implementation manner, a light shielding structure is further arranged in the pen barrel. The light shielding structure is a non-light transmission structure and is annularly arranged between the light guide structure and the pen barrel. In the direction perpendicular to the length direction of the pen barrel, at least part of the light guide structure is arranged in a stacked mode with the light shielding structure.

[0033] With the above scheme, the assembly gap exists between the cap and the pen barrel, the light shielding structure is arranged around the light guide structure and the pen barrel, and light leakage from the assembly gap can be prevented to avoid affecting the light emitting effect of the cap.

[0034] In a possible implementation, the cap includes a top portion and a ring-shaped flange connected to the outer periphery of the top portion, the first part and the second part of the outer surface are located on the top portion, and the ring-shaped flange is arranged in the pen barrel.

[0035] The ring-shaped flange is arranged around the light guide structure and the pen barrel, and in the length direction of the pen barrel, the light shielding structure has first and second end faces opposite to each other, the first end face of the light shielding structure is located on the side of the first end face of the light guide structure away from the cap, the second end face of the light shielding structure is arranged opposite to the end face of the ring-shaped flange toward the light source and is located between the first and second end faces of the light guide structure, and the end face of the ring-shaped flange toward the light source is located on the side of the second end face of the light guide structure close to the light source.

[0036] With the above scheme, in the length direction of the pen barrel, a part of the light guide structure close to the light source is nested in the light shielding structure to prevent light from leaking from the outer wall of this part of the light guide structure and prevent light leakage from the assembly gap between the cap and the pen barrel. A part of the light guide structure close to the cap is nested inside the ring-shaped flange of the cap, thereby guiding the light into the cap.

[0037] In a possible implementation, the cap includes a top portion and a ring-shaped flange connected to the outer periphery of the top portion, the first part and the second part of the outer surface are located on the top portion, the ring-shaped flange is arranged in the pen barrel, and the light shielding structure is arranged around the ring-shaped flange and the pen barrel.

[0038] In the length direction of the pen barrel, the light shielding structure has first and second end faces opposite to each other, the end face of the ring-shaped flange toward the light source is arranged opposite to the second end face of the light guide structure, the first end face of the light shielding structure is located on the side of the first end face of the light guide structure away from the cap, and the second end face of the light shielding structure is located on the side of the end face of the ring-shaped flange toward the light source away from the light source.

[0039] With the above scheme, the light guide structure and the ring-shaped flange are arranged opposite to each other, and light is butt-jointed through the end faces. A part of the light shielding structure close to the light source is sleeved outside the light guide structure to prevent light leakage from the outer wall of the light guide structure. A part of the light shielding structure close to the cap is sleeved outside the ring-shaped flange to prevent light leakage from the outer wall of the ring-shaped flange, thereby preventing light from leaking from the assembly gap between the cap and the pen barrel.

[0040] In a possible implementation, the light shielding structure is integrally formed on the surface of the light guide structure, or the light guide structure is integrally formed on the surface of the light shielding structure.

[0041] Adopting the above scheme, the light-shielding structural member and the light-guiding structural member can be integrally formed by double-color injection molding or the like, and have high connection strength and simple process.

[0042] In a possible implementation, the surface of the light-shielding structural member on the side away from the light-guiding structural member is fixedly connected with the inner wall surface of the pen barrel. Fixing the light-shielding structural member and the pen barrel together can improve the structural strength and stability of the region where the light-shielding structural member is located, and prevent the light-shielding structural member, the light-guiding structural member, and the like from being separated from the installation position in scenarios such as dropping of the stylus.

[0043] In a possible implementation, the second part of the outer surface is annular. When the light source emits light, the annular light band on the cap can be lit.

[0044] In a possible implementation, the light source is a plurality of light sources, the plurality of light sources are arranged at intervals along the circumference of the pen barrel, and the material of the base body of the cap includes light-uniformizing powder.

[0045] Adopting the above scheme, arranging a plurality of light sources at intervals along the circumference of the pen barrel can make the distribution of the light sources more dispersed, and to a certain extent, can improve the uniformity of the brightness of the light ring. On this basis, increasing the light-uniformizing powder in the cap improves the scattering effect of the cap on light, so that the light can uniformly propagate in the cap, and the brightness of the light ring is more uniform.

[0075] The specific embodiments of the present application will be described hereinafter by specific embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the content disclosed in the specification. Although the description of the present application will be introduced in combination with some embodiments, this does not mean that the features of the present application are limited to the embodiments. On the contrary, the purpose of introducing the present application in combination with the embodiments is to cover other options or modifications that can be extended based on the claims of the present application. In order to provide a deep understanding of the present application, many specific details will be included in the following description. The present application can also be implemented without using these details. In addition, in order to avoid confusion or obscure the focus of the present application, some specific details will be omitted in the description. It should be noted that the embodiments and features in the embodiments in the present application can be combined with each other without conflict.

[0076] It should be noted that in the specification, similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0077] Hereinafter, the terms that may appear in the embodiments of the present application are explained.

[0078] In the description of the present application, it should be noted that the orientations or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0079] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0080] In the description of the present application, it should be understood that "electrically connected" in the present application can be understood as that the components are in physical contact and electrically conductive; or can be understood as that the different components are connected through the entity line which can transmit electric signal such as copper foil or wire of printed circuit board (PCB) in the line configuration.

[0081] Opposite / Relative arrangement: A and B opposite arrangement can mean that A and B are arranged opposite to each other or face to face. For example, when two components are arranged opposite to each other, the two components are arranged with at least partial area overlapping in a certain direction.

[0082] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0083] Many appearance structural parts of consumer products need to be partially transparent, and other areas need to be opaque. For example, the cap (or tail) of some electronic stylus is configured with a light strip. When the light source inside the pen barrel emits light, the light is transmitted from the light strip of the cap, and other areas are opaque, thereby presenting the appearance effect of partial light emission of the cap. Currently, there are mainly two methods to achieve this effect, which will be introduced one by one below with reference to the drawings.

[0084] Please refer to Figures 1 to 3d , Figure 1 is a partial structure view of the electronic device in the first reference design; Figure 2 is a structure schematic view of the appearance structural part in the second reference design; Figures 3a to 3d is a processing step schematic view of the appearance structural part in the second reference design.

[0085] As shown in Figure 1 , in the first reference design, the electronic device 100' (such as an electronic stylus) is internally provided with a light source 61', and the appearance structural part 100' (such as a cap) is provided with a light hole 1001', and the light emitted by the light source 61' can be transmitted from the light hole 1001'. The device is also provided with a light guide structure 7' inside the device. The light guide structure 7' is a light-transmitting structure, one end of which faces the light source 61', and the other end of which faces the light hole 1001', guiding the light emitted by the light source 61' to the light hole 1001'. The appearance structural part 100' is only transparent at the light hole 1001', and other parts are opaque, thereby realizing the effect of partial light transmission. However, this scheme needs to open a hole on the appearance structural part 100', and there is a clear appearance gap between the hole and other parts, which destroys the consistency of the appearance.

[0086] As shown in Figure 2As shown, in the second reference design, the exterior structural component 100" includes a substrate 1", and opaque paint 21" and translucent paint 22" stacked on the outer surface of the substrate 1". The substrate 1 and translucent paint 22" are translucent structures, while the opaque paint 21" is an opaque structure. In an example scenario, the processing flow of the exterior structural component 100" may include:

[0087] 1. For example Figure 3a As shown, the substrate 1 of the exterior structural component 100 is made of a light-transmitting material.

[0088] 2. For example Figure 3b As shown, an opaque paint 21 is sprayed onto the surface of substrate 1".

[0089] 3. For example Figure 3c As shown, the opaque paint 21” in the area that needs to emit light (i.e., the area within the dotted box in the figure) is removed by laser engraving.

[0090] 4. For example Figure 3d As shown, a translucent paint 22” is sprayed onto the laser-engraved surface, so that the translucent paint 22” covers the opaque paint 21” and the area of ​​the appearance structural component 100” where the opaque paint 21” has been removed.

[0091] After the above steps are completed, the area on the exterior structural component 100” covered by the opaque paint 21” is an opaque area, and the area not covered by the opaque paint 21 is a translucent area, thus achieving the effect of partial light transmission.

[0092] The translucent paint 22” not only allows light to pass through but also gives the exterior structural component 100” a specific color, such as white, yellow, or blue. When the exterior structural component 100” is applied to electronic devices containing a light source, the light only passes through the translucent area when the light source is emitting light. When the light source is not emitting light, since the translucent paint 22” covers both the translucent and opaque areas, there is no obvious difference between the two areas. The exterior structural component 100” can present the color of the translucent paint 22” as a whole, maintaining a consistent appearance.

[0093] However, the current opaque paint 21” is quite thick, around 20μm, and cannot be less than 10μm. When spraying the translucent paint 22”, the translucent paint 22” needs to first fill the grooves formed when the opaque paint 21” was removed by laser engraving (i.e. Figure 3c The gaps within the dashed frame are then filled with opaque paint 21”, and the surface of the translucent paint 22” within the grooves is then completely covered. Because the opaque paint 21” is relatively thick, the height difference between the area where the opaque paint 21” was removed after laser engraving and the area where it remains is significant (or the grooves formed by laser engraving are deeper), which can easily cause uneven application of the translucent paint 22” in the subsequent spraying.Figure 3d As shown, the surface of the light-transmitting color paint 22" is uneven, resulting in an uneven surface of the appearance structure 100", and there is still a relatively obvious appearance gap between the light-transmitting region and the non-light-transmitting region of the appearance structure 100", and the appearance effect is poor. Especially when the light-transmitting color paint 22" is a light-colored paint such as white, the hiding power is poor, and the appearance gap is more obvious.

[0094] As can be seen, the appearance gap between the light-transmitting region and the non-light-transmitting region in the appearance structure that is partially light-transmitting in the prior art is obvious, which destroys the consistency and aesthetics of the appearance, and the appearance effect is poor.

[0095] To solve the above problems, an appearance structure is provided in the embodiments of the present application, which improves the uniformity of the sprayed color paint by thinning the thickness of the light-shielding layer on the appearance structure.

[0096] Please refer to Figures 4 to 6 , Figure 4 for a structure diagram of the appearance structure in the embodiments of the present application Figure 1 . Figure 5 for a structure diagram of the appearance structure in the embodiments of the present application Figure 2 . Figure 6 for a structure diagram of the appearance structure in the embodiments of the present application

[0097] As Figure 4 shown, the appearance structure 100 includes a base body 1 and a film layer 2, the base body 1 is a light-transmitting structure and has an outer surface 11, the outer surface 11 includes a first part 111 and a second part 112 arranged in connection, and the film layer 2 is arranged on the first part 111 and the second part 112.

[0098] The base body 1 is a light-transmitting structure and can allow light to pass through. The base body 1 has an outer surface 11, and the film layer 2 is arranged on the outer surface 11. The outer surface 11 can be understood as a part of the outer surface of the appearance structure 100 on which the film layer 2 is arranged, which can be the whole or a part of the outer surface of the appearance structure 100. When the appearance structure 100 is part of the appearance of a product, the film layer 2 arranged on the outer surface 11 can be exposed and part of the appearance of the product, which can protect the outer surface 11 and present a specific appearance effect. As Figure 4 shown, in one possible implementation, the outer surface 11 is a part of the outer surface of the appearance structure 100, that is, only a part of the outer surface of the appearance structure 100 is covered with the film layer 2. In some possible implementation, the outer surface of the appearance structure 100 can also be covered with the film layer 2 as a whole, which is not limited in the embodiments of the present application. It should be noted that the "light-transmitting structure" mentioned in the embodiments of the present application can be completely light-transmitting, such as a transparent structure, or semi-transparent and semi-light-transmitting structure, as long as the structure can allow light to pass through, which is within the scope of the "light-transmitting structure".

[0099] Further, the film layer 2 comprises an opaque layer 21 and a light-transmitting layer 22. The opaque layer 21 is a film-coated structure and is arranged on the first part 111 of the outer surface 11, and the opaque layer 21 is a non-light-transmitting structure. The light-transmitting layer 22 is arranged on the second part 112 of the outer surface 11 and the surface of the opaque layer 21 away from the base 1, and the light-transmitting layer 22 has a color and is a light-transmitting structure. The thickness of the opaque layer 21 is less than 10 μm. It should be noted that the “non-light-transmitting structure” mentioned in the embodiments of the present application can be a structure that can completely block light, or a structure in which the brightness of light can be greatly weakened after the light passes through, or can be understood as a structure with low light transmission, which is not limited in the embodiments of the present application.

[0100] In the appearance structure 100 provided by the embodiments of the present application, the film layer 2 comprises an opaque layer 21 and a light-transmitting layer 22, wherein the opaque layer 21 is a non-light-transmitting structure and can block light. The light-transmitting layer 22 not only can transmit light, but also can show rich and colorful colors, so that the entire outer surface 11 presents a designed color effect. The outer surface 11 comprises a first part 111 and a second part 112, the opaque layer 21 only covers the first part 111, and the second part 112 can still transmit light. It can be understood that the second part 112 is a light-transmitting region of the outer surface 11, and the first part 111 is a non-light-transmitting region, so that the appearance structure 100 can realize the effect of transmitting light in a local region. The light-transmitting layer 22 covers the opaque layer 21 and the second part 112 of the outer surface 11, and it can be understood that the light-transmitting layer 22 covers the light-transmitting region and the non-light-transmitting region of the outer surface 11 at the same time.

[0101] The opaque layer 21 is a film-coated structure, and the thickness of the opaque layer 21 is less than 10 μm. The film-coated structure is a film layer structure formed by electroplating or other processes. When the thickness is relatively thin, the height difference between the region (the first part 111) on the first surface where the opaque layer 21 is arranged and the region (the second part 112) where the opaque layer 21 is not arranged is small. When the light-transmitting color paint 22 is sprayed, the gap (which can be understood as the gap formed by the second part 112 being recessed relative to the opaque layer 21 on the first surface) to be filled by the light-transmitting color paint 22 is shallow. Therefore, the light-transmitting color paint 22 can realize similar or even equivalent covering force on the opaque layer 21 and the second part 112 of the outer surface 11. The surface of the light-transmitting color paint 22 is relatively uniform, the appearance difference between the light-transmitting region and the non-light-transmitting region on the appearance structure 100 is small, the consistency is strong, and the whole is relatively beautiful.

[0102] Therefore, the appearance structure 100 provided by the embodiments of the present application has small appearance difference between the light-transmitting region and the non-light-transmitting region, good overall appearance effect, strong consistency and relatively beautiful.

[0103] It should be noted that the specific material of the base 1 is not limited, for example, it can include acrylic or PC (Polycarbonate, polycarbonate), as long as it can transmit light. In one possible implementation, the material of the base 1 includes transparent PC, which has high transparency and light transmittance of more than 89%, close to the light transmittance of glass. And the strength of PC is high, the toughness is good, and it is anti-falling and durable. In some possible implementations, uniform light powder can also be added to the transparent PC, which can improve the scattering effect of light and make the light propagate uniformly in the base 1, so that the brightness of the light transmission area is more uniform. Other materials can also be doped in the base 1 according to actual needs, which is not limited by the embodiments of the application.

[0104] It should be noted that the specific material and formation of the light shielding layer 21 are not limited. In some possible implementations, the light shielding layer 21 can be processed by vacuum plating or NCVM process (Non-Conductive Vacuum Metallization, non-conductive vacuum metallization technology). Vacuum plating is a process of depositing a thin film on the surface of an object in a vacuum environment through physical or chemical methods, including vacuum evaporation plating (in a vacuum chamber, the material in the evaporation source is heated to vaporize and deposit on the surface of the substrate to form a thin film), PVD vacuum plating (Physical Vapor Deposition, physical vapor deposition vacuum plating, depositing a thin film on the surface of the substrate by physical method), vacuum electroplating (depositing a metal thin film on the surface of an object in a vacuum environment by electrochemical method), ion plating (plating under vacuum conditions by gas discharge), etc. The specific type and operation of the vacuum plating are not limited by the embodiments of the application. The thickness of the plating film structure obtained by vacuum plating is usually thin, generally micron level, and the specific thickness range varies with the process and application requirements, and the overall thickness can be less than 10 μm. The NCVM process is a high-tech evolved from traditional vacuum plating technology. By plating a metal thin film and an insulating compound thin film on the surface of a non-conductive substrate such as plastic, a discontinuous structure is formed, which gives the product a metallic appearance. The thickness of the plating film structure obtained by the NCVM process can also be less than 10 μm. The light shielding layer 21 can also be a plating film structure obtained by other processes, which is not limited by the embodiments of the application.

[0105] The thickness of the light shielding layer 21 is not limited, for example, as shown in Figure 4 In one possible implementation, the thickness h1 of the light shielding layer 21 is in the range of 2 μm to 5 μm, for example, 2 μm, 2.5 μm, 3.2 μm, 5 μm, etc., and the specific thickness is not limited. Within this range, the thickness of the light shielding layer 21 is thin enough and has good light shielding effect. In some possible implementations, the thickness h1 of the light shielding layer 21 can also be less than 2 μm or greater than 5 μm, which is not limited by the embodiments of the application.

[0106] In a possible implementation, the material of the light-shielding layer 21 is metal or alloy. The metal and alloy can be easily prepared by electroplating or other methods, and a film layer 2 with a required thickness is formed. The metal and alloy have strong luster, and can add texture to the appearance structure 100. Specifically, the material of the light-shielding layer 21 can be silver, copper, aluminum, iron, aluminum alloy, or the like, which is not limited in the application. In a possible implementation, the material of the light-shielding layer 21 is silver. The silver plating layer has strong metal luster, high-end appearance, good process repeatability, and is suitable for mass production, which can ensure the stability and consistency of product quality. It should be noted that the material of the light-shielding layer 21 can also be non-metal such as plastic, which is not limited in the embodiments of the application.

[0107] The specific material of the light-transmitting layer 22 is not limited, for example, it can be colored paint or glue. In a possible implementation, the material of the light-transmitting layer 22 is paint, which can be attached to the light-shielding layer 21 and the outer surface 11 by spraying. The spraying has a wide and uniform distribution area. The light-transmitting layer 22 can also be processed by painting or other methods, which is not limited in the embodiments of the application.

[0108] The color of the light-shielding layer 21 and the light-transmitting layer 22 is not limited. In a possible implementation, the color of the light-shielding layer 21 is black. As can be understood by those skilled in the art, black has the strongest light-shielding ability, and the light-shielding layer 21 in black can prevent the non-transparent area of the appearance structure 100 from leaking light, and has better light effect. In addition, the light-shielding layer 21 can also be dark gray, dark brown, or other darker colors, which is not limited in the embodiments of the application.

[0109] In a possible implementation, the color of the light-transmitting layer 22 is white. White has good light-transmitting effect, and can make the outer surface 11 of the appearance structure 100 have an integrated white appearance, which is simple, elegant, and timeless. The color of the light-transmitting layer 22 can also be blue, yellow, green, or other colors, or can also be colored, which is not limited in the embodiments of the application.

[0110] As Figure 4As shown, in one possible implementation, the thickness h2 of the portion of the light-transmitting layer 22 covering the light-shielding layer 21 is in the range of 35μm-45μm. Within this range, the light-transmitting layer 22 can not only completely compensate for the height difference between the second portion 112 on the outer surface 11 and the light-shielding layer 21, but also present a smooth and uniform surface, and has strong covering ability, preventing color transmission between the outer surface 11 and the covering layer, thereby further reducing the appearance difference between the light-transmitting area and the opaque area. The specific thickness of the portion of the light-transmitting layer 22 covering the light-shielding layer 21 can be 35μm, 35.2μm, 38μm, 43μm, 45μm, etc., and this application embodiment does not limit this. In some possible implementations, the thickness h2 of the portion of the light-transmitting layer 22 covering the light-shielding layer 21 can also be less than 35μm or greater than 45μm, and this application embodiment does not limit this.

[0111] like Figure 5 As shown, in one possible implementation, the light-transmitting layer 22 includes a first layer 221 and a second layer 222 stacked together. The first layer 221 covers the second portion 112 of the outer surface 11 and the surface of the light-shielding layer 21 facing away from the substrate 1. The second layer 222 covers the surface of the first layer 221 facing away from the light-shielding layer 21. Alternatively, the light-transmitting layer 22 can be understood as two layers that can be sprayed separately. First, the first layer 221 is sprayed to compensate for the height difference between the second portion 112 on the outer surface 11 and the light-shielding layer 21, providing initial coverage of the light-shielding layer 21 and the second portion 112 of the outer surface 11. Then, the second layer 222 is sprayed to make the surface of the light-transmitting layer 22 more uniform, achieving a better spraying effect. Those skilled in the art will understand that the composition of the first layer 221 and the second layer 222 can be completely identical, and there is no obvious dividing line between them. The dividing line in the attached figures is only for distinguishing the thickness of the first layer 221 and the second layer 222.

[0112] like Figure 5As shown, in one possible implementation, the thickness h21 of the portion of the first layer 221 covering the light-shielding layer 21 is in the range of 18μm-22μm, and the thickness h22 of the second layer 222 is in the range of 18μm-22μm. Controlling the thickness of both layers within the range of 18μm-22μm allows for a more uniform coating surface. Specifically, the thickness of each layer can be 18μm, 19μm, 22μm, etc., and can be set according to actual needs. In some possible implementations, the thickness of each layer can also be less than 18μm or greater than 22μm; this application embodiment does not impose any limitations on this. The thickness h21 of the portion of the first layer 221 covering the light-shielding layer 21 and the thickness h22 of the second layer 222 can be exactly the same or different, and the materials of the two layers can be exactly the same or different; this application embodiment does not impose any limitations on this. In some possible implementations, the light-transmitting layer 22 can also include 3, 4, or more layers; this application embodiment does not impose any limitations on this.

[0113] like Figure 6 As shown, in one possible implementation, the film layer 2 further includes a protective layer 23. The protective layer 23 is a light-transmitting structure and is applied to the surface of the light-transmitting layer 22 facing away from the substrate 1. The protective layer 23 can protect the surface of the light-transmitting layer 22, prevent fading, and provide a good skin-friendly feel, improving touch comfort. The material of the protective layer 23 is not limited. In one possible implementation, the material of the protective layer 23 is a transparent UV (Ultraviolet Curing Material). Transparent UV has good light transmittance, does not affect the light transmission and appearance of the appearance structural component 100, and can form a tough coating after UV curing, with high wear resistance, providing good protection for the appearance structural component 100.

[0114] Please see Figures 7a to 7f , Figures 7a to 7f This is a schematic diagram of the processing steps for the appearance structural component in an embodiment of this application.

[0115] In one possible implementation, the processing technology of the exterior structural component 100 includes:

[0116] 1. For example Figure 7a As shown, a transparent PC doped with homogenizing powder is used to make the substrate 1.

[0117] 2. For example Figure 7bAs shown, a light-shielding coating structure is processed on the outer surface 11 of the substrate 1. In one possible implementation, a coating structure can be formed on the outer surface 11 by vacuum deposition or NCVM process. Specifically, the substrate 1 can be cleaned and surface activated, then placed in a vacuum chamber, heated to evaporate the coating material and deposit it on the outer surface 11 to form a thin film. Subsequent post-processing processes such as cooling and inspection can also be performed; the specific operation process is not limited in this embodiment.

[0118] 3. For example Figure 7c As shown, the coating structure of the second part 112 of the outer surface 11 is removed, while the coating structure of the first part 111 is retained and serves as a light-shielding layer 21.

[0119] 4. For example Figure 7d As shown, a first layer of colored paint is sprayed onto the light-shielding layer 21 and the second part 112 of the outer surface 11, and after curing, it serves as the first layer 221.

[0120] 5. For example Figure 7e As shown, a second layer of colored paint is sprayed onto the surface of the first layer 221, and after curing, it becomes the second layer 222.

[0121] 6. For example Figure 7f As shown, a transparent UV coating is sprayed onto the surface of the second layer 222, which, after curing, serves as a protective layer 23.

[0122] The substrate 1 can be fabricated, for example, by injection molding; the coated structure can be processed, for example, by vacuum plating; and the coated structure of the second part 112 of the outer surface 11 can be removed, for example, by laser engraving. This application embodiment does not limit these methods. The above process is merely illustrative; in actual production, it may include more or fewer steps than described above, and this application embodiment does not limit these methods.

[0123] The appearance structural component 100 produced by the above process not only meets the requirements of partial light transmission and integrated color appearance, but also has a good appearance effect and skin-friendly touch, with no obvious step difference between the light-transmitting area and the opaque area.

[0124] Those skilled in the art will understand that the shape and structure of the appearance structural component 100, as well as the shape of the outer surface 11 and the distribution of the first part 111 and the second part 112, are all related to the specific application scenario of the appearance structural component 100, and the embodiments of this application do not limit this. In one possible implementation, the appearance structural component 100 is the cap of the electronic stylus 200. The structure and appearance of the cap will be further described below with reference to the accompanying drawings.

[0125] Please see Figures 8 to 11 , Figure 8 This is a schematic diagram of the structure of the electronic stylus according to an embodiment of this application; Figure 9This is a partial structural diagram of the electronic stylus according to an embodiment of this application; Figure 10 This is a partial structural breakdown diagram of the electronic stylus in an embodiment of this application. Figure 1 ; Figure 11 A partial structural cross-section of the electronic stylus according to an embodiment of this application. Figure 1 .

[0126] like Figure 8 As shown in the illustration, this application also provides an electronic stylus 200. The electronic stylus 200 can be a standalone product or an add-on device used with electronic devices such as mobile phones, tablets, laptops, and touchscreens; this application does not impose any limitations on this. The specific type of the electronic stylus 200 can be a capacitive stylus, an electromagnetic induction stylus, a Bluetooth stylus, etc.; this application does not impose any limitations on this.

[0127] like Figure 8 , Figure 9 As shown, the electronic stylus 200 may include a pen barrel 3, and a pen tip 4 and a pen cap 5 respectively disposed at both ends of the pen barrel 3. The pen barrel 3 is the main body of the electronic stylus 200, which can be gripped, and houses multiple components. The pen tip 4 can be used for clicking, writing, drawing graphics, and other operations on the touchscreen. The pen cap 5 is located at the tail end of the pen barrel 3, also known as the pen tail of the electronic stylus 200; the portion of the pen cap 5 protruding from the pen barrel 3 can serve as part of the housing of the electronic stylus 200.

[0128] This application does not limit the application of the pen cap 5. Those skilled in the art will understand that the pen cap 5 can be fixedly connected to the pen barrel 3 and used simply as a housing. In some scenarios, the pen cap 5 can also be designed as a pressable structure relative to the pen barrel 3 to trigger corresponding operations of the internal parts of the pen barrel 3. Alternatively, the pen cap 5 can be detachably connected to the pen barrel 3, allowing it to be removed and used as an independent product.

[0129] This application does not limit the type and specific function of the internal components of the electronic stylus 200. In one possible implementation, the electronic stylus 200 may have a processor, which may include storage and processing circuitry for supporting the operation of the electronic stylus 200 and controlling the electronic stylus 200 to perform various operations. The processing circuitry may be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio chips, application-specific integrated circuits, etc., and this application does not limit this.

[0130] For example, during the operation of the electronic stylus 200, the software running on the processor can process sensor input, button input, and input from other devices to monitor the movement of the electronic stylus 200 and user input, and can also detect user commands and communicate with the matching electronic device. In order to support the wireless communication between the electronic stylus 200 and the matching electronic device, the electronic stylus 200 can also include a wireless module. The wireless module can be, for example, a Bluetooth module, a WIFI hotspot module, a WIFI point-to-point module, etc., and the embodiments of the present application do not limit this.

[0131] The electronic stylus 200 can also include a charging module to support the charging and discharging function of the electronic stylus 200 and provide power for the electronic stylus 200.

[0132] The electronic stylus 200 can include more or fewer functional modules than the above examples, and the embodiments of the present application do not limit this.

[0133] The electronic stylus 200 provided in the embodiments of the present application also includes an appearance structure 100. In one possible implementation, the surface of the film layer 2 in the appearance structure 100 away from the base 1 constitutes at least part of the outer surface of the electronic stylus 200. By taking the appearance structure 100 as part of the appearance of the electronic stylus 200, the partial light transmission of the shell of the electronic stylus 200 can be realized, and when the internal light source 61 of the stylus does not emit light, the overall consistency of the appearance of the stylus is high, and the appearance of the light transmission area and the non-light transmission area has small difference. Specifically, the appearance structure 100 can be the cap 5 of the electronic stylus 200, or the pen barrel 3, or a part of the pen barrel 3, etc., and the embodiments of the present application do not limit this.

[0134] As shown in Figures 9 to 11 In one possible implementation, the appearance structure 100 is the cap 5 of the electronic stylus 200, and the outer surface of the part of the cap 5 outside the pen barrel 3 constitutes the outer surface 11. The pen barrel 3 is provided with a light source 61, and the light emitted by the light source 61 transmits out of the pen barrel 3 through the second part 112 (the area inside the annular dashed line) of the outer surface 11 in the cap 5. The specific type of the light source 61 is not limited, which can be, for example, an LED lamp, a fluorescent lamp, an incandescent lamp, a halogen lamp, etc. Figure 9

[0135] With this structure, the second part 112 of the outer surface 11 corresponds to the light transmission area (which can be understood as a lamp strip) of the cap 5, and the first part 111 is the non-light transmission area. The light emitted by the light source 61 only transmits out of the light transmission area, and the other areas are not light-transmissive, thereby realizing the effect of partial light transmission of the cap 5. Moreover, by designing the first part 111 and the second part 112 of the outer surface 11 into various shapes, a variety of light effects can also be realized.

[0136] ​It should be noted that the specific shape of the second part 112 is not limited. Or it can be understood that the specific shape of the light strip on the pen cap 5 is not limited. As shown in Figure 9 In one possible implementation, the second part 112 of the outer surface 11 is annular. When the light source 61 emits light, a light ring on the pen cap 5 can be lit. In some possible implementations, the second part 112 can also be circular, rectangular, irregular, or set in a special pattern, which can be flexibly designed according to the overall appearance of the stylus.

[0137] As shown in Figure 10 , Figure 11 In one possible implementation, the light source 61 is multiple, and the multiple light sources 61 are arranged at intervals along the circumference of the pen barrel 3. The material of the pen cap 5 includes a light uniforming powder. The specific number of light sources 61 can be 2, 3 or more, which is not limited by the embodiments of the present application. As shown in Figure 10 In one possible implementation, the number of light sources 61 is two. As can be understood by those skilled in the art, the light source 61 inside the stylus is usually a point light source 61, and the light ring is annular. When the number of light sources 61 is small (for example, only one light source 61), the brightness of the light ring is uneven, and local over-brightness and local over-darkness are prone to occur. Arranging multiple light sources 61 at intervals along the circumference of the pen barrel 3 can make the distribution of the light sources 61 more dispersed, and to a certain extent, can improve the uniformity of the brightness of the light ring. On this basis, increasing the light uniforming powder in the pen cap 5 improves the scattering effect of the pen cap 5 on light, which can make the light propagate uniformly in the pen cap 5, so that the brightness of the light ring is more uniform, and the brightness is consistent everywhere. In some possible implementations, only one light source 61 can be provided, and the material of the pen cap 5 can also not include light uniforming powder, which is not limited by the embodiments of the present application.

[0138] As shown in Figure 10 , Figure 11 In one possible implementation, the pen cap 5 is a structure that can be pressed relative to the pen barrel 3. When the pen cap 5 is pressed, the light source 61 switch can be triggered to perform operations such as turning on the light and turning off the light. Specifically, the pen cap 5 includes a guide column 53, the guide column 53 is sleeved with an elastic member 62, and the light source 61 is installed on a circuit board 64. The circuit board 64 is also provided with a trigger piece 63, the trigger piece 63 is electrically connected with the light source 61, and is used for controlling the light source 61 to emit light or extinguish. One end of the guide column 53 abuts against the trigger piece 63. For example, when the pen cap 5 is pressed, the guide column 53 extrudes the trigger piece 63, so that the internal circuit of the trigger piece 63 is conducted, a trigger signal is sent to the light source 61, and the light source 61 is controlled to emit light. When the pressing force applied to the pen cap 5 is removed, the pen cap 5 automatically rebounds under the elastic force of the elastic member 62. If the pen cap 5 is pressed again, the guide column 53 extrudes the trigger piece 63 again, and the trigger piece 63 can send a trigger signal to the light source 61 again to extinguish the light source 61.

[0139] The trigger 63 may be, for example, a travel switch, and the specific type and structure of the trigger 63 is not limited in the embodiments of the present application. The elastic member 62 may be, for example, a spring, and the specific type of the elastic member 62 is not limited in the embodiments of the present application. The guide column 53 may be in an integral structure with other parts of the cap 5, or may be in a separate structure, and the specific type of the guide column 53 is not limited in the embodiments of the present application.

[0140] It should be noted that the pressing structure and the control circuit are only examples, and the embodiments of the present application are not limited to the examples. In some possible implementations, the electronic stylus 200 may also be controlled to perform operations other than switching on / off the light, such as controlling a matched electronic device to take a photo, record a video, or play music, and the embodiments of the present application are not limited in this regard.

[0141] As shown in FIG. 7, Figure 10 Figure 11 In a possible implementation, the pen barrel 3 further comprises a light guide structure 7, which is a light-transmitting structure. The light guide structure 7 has a first end face 71 and a second end face 72 opposite to each other in the length direction L of the pen barrel. The first end face 71 of the light guide structure 7 is arranged opposite to the light source 61, and the second end face 72 of the light guide structure 7 is arranged opposite to the cap 5.

[0142] The light guide structure 7 is capable of transmitting light, and the two end faces 521 of the light guide structure 7 are arranged opposite to the light source 61 and the cap 5 respectively, so as to guide the light of the light source 61 to be more concentratedly transmitted to the cap 5. The specific material of the light guide structure 7 is not limited, and in some possible implementations, the light guide structure 7 may also be made of acrylic or transparent PC mixed with light-uniformizing powder, which not only has good light-transmitting property, but also enhances the scattering effect of the light, so that the light of the light source 61 is uniformly dispersed to all regions of the light ring of the cap 5, and the light ring is uniformly bright.

[0143] It should be noted that the specific shape of the light guide structure 7 is not limited, and the light guide structure 7 is only schematically shown in the drawings. In a possible implementation, the light guide structure 7 is in an annular columnar structure, so as to cooperate with the annular light-transmitting region, and the annular columnar structure can accommodate the elastic member 62 and the guide column 53, so as to make full use of the space.

[0144] As shown in FIG. 7, Figure 10 Figure 11 In a possible implementation, the pen barrel 3 further comprises a light shielding structure 8, which is a light-blocking structure and is annularly arranged between the light guide structure 7 and the pen barrel 3. At least part of the light guide structure 7 is arranged in a stacked manner with the light shielding structure 8 in a direction perpendicular to the length direction L of the pen barrel. It can be understood by those skilled in the art that there is an assembly gap A between the cap 5 and the pen barrel 3, and the light shielding structure 8 is annularly arranged between the light guide structure 7 and the pen barrel 3, so as to prevent the light from leaking out of the assembly gap A, so as to avoid affecting the light-emitting effect of the cap 5.​​

[0145] The specific way the light-shielding structure 8, light-guiding structure 7, and pen cap 5 are matched is not limited. It should be flexibly set according to the space inside the pen barrel 3. Two possible solutions are described below with reference to the attached drawings.

[0146] like Figure 10 , Figure 11 As shown, in one possible implementation, the pen cap 5 includes a top 51 and an annular flange 52 connected to the outer periphery of the top 51. A first portion 111 and a second portion 112 of the outer surface 11 are located on the top 51, meaning the entire outer surface 11 is located on the top 51. The annular flange 52 is disposed within the pen barrel 3. Alternatively, the top 51 of the pen cap 5 is exposed outside the pen barrel 3, serving as part of the stylus's appearance and outer casing, while the annular flange 52 is embedded within the pen barrel 3. When the pen cap 5 is a pressable structure, the user can press the top 51 of the pen cap 5, causing the annular flange 52 to slide up and down relative to the inner wall of the pen barrel 3.

[0147] Furthermore, the annular flange 52 is arranged between the light guide structure 7 and the pen barrel 3. In the length direction L of the pen barrel, the light shielding structure 8 has a first end face 81 and a second end face 82 facing away from each other. The first end face 81 of the light shielding structure 8 is located on the side of the first end face 71 of the light guide structure 7 away from the pen cap 5. The second end face 82 of the light shielding structure 8 is arranged opposite to the annular flange 52 and is located between the first end face 71 and the second end face 72 of the light guide structure 7. The end face 521 of the annular flange 52 facing the light source 61 is located on the side of the second end face 72 of the light guide structure closer to the light source 61.

[0148] This can be understood as follows: along the length L of the pen barrel, a portion of the light-guiding structure 7 near the light source 61 is nested within the light-shielding structure 8 to prevent light from leaking out from the outer wall of this portion of the light-guiding structure 7, thus preventing light leakage at the assembly gap A between the pen cap 5 and the pen barrel 3. The portion of the light-guiding structure 7 near the pen cap 5 is nested inside the annular flange 52 of the pen cap 5, thereby guiding light into the pen cap 5.

[0149] like Figure 11 As shown, in one possible implementation, the second end face 82 of the light-shielding structure 8 and the annular flange 52 are spaced apart to reserve pressing space for the pen cap 5. In some possible implementations, if the pen cap 5 does not adopt a pressing design, the second end face 82 of the light-shielding structure 8 and the annular flange 52 can also directly abut against each other to enhance the light leakage prevention effect. This application embodiment does not limit this.

[0150] Please see Figures 12 to 13 , Figure 12 This is a partial structural exploded view of the electronic stylus in an embodiment of this application. Figure 2 ; Figure 13A partial structural cross-section of the electronic stylus according to an embodiment of this application. Figure 2 .

[0151] People like Figures 12 to 13 As shown, in one possible implementation, the light-shielding structure 8 is arranged in a ring between the annular flange 52 and the pen barrel 3. Along the length L of the pen barrel, the end face 521 of the annular flange 52 facing the light source 61 is opposite to the second end face 72 of the light guide structure 7. The first end face 81 of the light-shielding structure 8 is located on the side of the first end face 71 of the light guide structure 7 away from the pen cap 5, and the second end face 82 of the light-shielding structure 8 is located on the side of the end face 521 of the annular flange 52 facing the light source 61 away from the light source 61.

[0152] This can be understood as follows: the light guide structure 7 and the annular flange 52 are arranged opposite each other, and the two are connected by the end face 521. A portion of the light-shielding structure 8 near the light source 61 is fitted over the light guide structure 7 to prevent light leakage from the outer wall of the light guide structure 7. A portion of the light-shielding structure 8 near the pen cap 5 is fitted over the annular flange 52 to prevent light leakage from the outer wall of the annular flange 52, thereby preventing light from leaking out from the assembly gap A between the pen cap 5 and the pen barrel 3.

[0153] like Figure 13 As shown, in one possible implementation, the second end face 82 of the light-shielding structure 8 is spaced apart from the top 51 of the pen cap 5 to reserve pressing space for the pen cap 5. In some possible implementations, if the pen cap 5 does not adopt a pressing design, the second end face 82 of the light-shielding structure 8 and the top 51 of the pen cap 5 can also directly abut against each other to enhance the light leakage prevention effect. This application embodiment does not limit this.

[0154] In one possible implementation, the light-shielding structural component 8 is integrally formed on the surface of the light-guiding structural component 7, or the light-guiding structural component 7 is integrally formed on the surface of the light-shielding structural component 8. Alternatively, the light-shielding structural component 8 and the light-guiding structural component 7 can be integrally formed using methods such as two-color injection molding. For example, the light-shielding structural component 8 can be formed by injection molding with an opaque material first, and then the guiding structural component can be formed by injection molding with a translucent material in the same mold. Using this structure, the connection strength between the light-shielding structural component 8 and the light-guiding structural component 7 is high, and the process is simple. In some possible implementations, the light-guiding structural component 7 and the light-shielding structural component 8 can also be processed separately; this application does not limit this.

[0155] In a possible implementation, the surface of the light-shielding structure 8 on the side away from the light guide structure 7 is fixedly connected with the inner wall of the pen barrel 3. Specifically, the surface of the light-shielding structure 8 on the side away from the light guide structure 7 can be fixedly connected with the inner wall of the pen barrel 3 by means of gluing, welding, riveting or the like, and the present application is not limited in this regard. Fixing the light-shielding structure 8 with the pen barrel 3 together can improve the structural strength and stability of the region where the light-shielding structure 8 is located, and prevent the light-shielding structure 8, the light guide structure 7 and other components from being separated from the installation position in scenarios such as dropping of the stylus. In a possible implementation, the light-shielding structure 8 and the inner wall of the pen barrel 3 are fixed by gluing, thereby simplifying the production process and reducing the difficulty of fixing.

[0156] Those skilled in the art can understand that, in addition to the electronic stylus, the appearance structure 100 provided by the present application can also be applied to electronic devices such as mobile phones, computers, vehicle-mounted devices and personal digital devices, or applied to other fields, and the present application will not list them one by one.

[0157] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and equivalent technologies thereof, the present application also intends to include these modifications and variations.
