[0069] The above drawings show clear embodiments of the present disclosure, which will be described in more detail below. These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0070] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0071] The directional nouns involved in the embodiments of the present disclosure, such as "upper", "lower", "side", etc., are generally based on the relative directional relationship between the structures when the watch or injection mold is usually arranged, and these directional nouns are used only to more clearly describe the relationship between the structures, and are not intended to describe the absolute directional. When the watch or injection mold is placed in different postures, the directional may change, for example, "upper" and "lower" may be interchangeable.

[0072] Unless otherwise defined, all technical terms used in the embodiments of the present disclosure have the same meanings as commonly understood by those of ordinary skill in the art.

[0073] In order to make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0074] In the related art, reference Figure 1 , the watch may include a cover plate 01, a display component 02, a middle frame 03 and an adhesive layer 05, the middle frame 03 and the cover plate 01 protrude relative to the display component 02 to provide an adhesive area between the two, and the adhesive layer 05 is arranged between the middle frame 03 and the cover plate 01 to bond the middle frame 03 and the cover plate 01 together to achieve the assembly and packaging of the watch. Further, in order to prevent the display component 02 from interfering with the middle frame 03, a partial avoidance spacing needs to be reserved between the display component 02 and the middle frame 03. In this case, the frame size D of the watch is the sum of the size C of the non-display area of ​​the display component 02 (i.e., the frame of the display component itself), the avoidance spacing B between the display component 02 and the middle frame 03, and the width A of the adhesive layer 05. It should be noted that the frame of the watch generally refers to the structure of the watch outside the display area, which may include the frame of the display component itself (i.e., the non-display area) and the frame structure of the watch outside the display component for protecting the internal components.

[0075] In order to reduce the frame size of a watch, an embodiment of the present disclosure provides a watch. Figure 2 The watch of the embodiment of the present disclosure includes a cover plate 01, a display assembly 02, a middle frame 03 and a packaging member 04;

[0076] The cover plate 01, the display assembly 02 and the middle frame 03 are stacked in sequence;

[0077] The packaging component 04 is located between the cover plate 01 and the middle frame 03, and is connected or in contact with the cover plate 01 and the middle frame 03 respectively;

[0078] The orthographic projection of the package 04 on the cover plate 01 at least partially overlaps with the orthographic projection of the display component 02 on the cover plate 01 .

[0079] Since the packaging component generally does not affect the operation of the display component, in this embodiment, the packaging component can directly contact the display component without setting an avoidance distance.

[0080] In the disclosed embodiment, the packaging component of the watch is located between the cover plate and the middle frame, and is connected or in contact with the cover plate and the middle frame respectively, so as to achieve the packaging effect of the watch as a whole. Furthermore, the orthographic projection of the packaging component on the cover plate at least partially overlaps with the orthographic projection of the display component on the cover plate, and thus the effect of the packaging component on the frame size of the watch is at least partially offset by the effect of the non-display area of ​​the display component on the frame size, so that the frame size of the watch can be reduced, the proportion of the display area of ​​the watch can be increased, and the user experience is better.

[0081] To make the technical effect of the technical solution of the embodiment of the present disclosure easier to understand, please refer to Figure 3 , the frame size D1 of the watch provided in the embodiment of the present disclosure is actually the sum of the size C of the non-display area of ​​the display component 02 (i.e., the frame area of ​​the display area itself) and the partial width A1 of the package, which corresponds to the portion where the orthographic projection of the package on the cover plate does not overlap with the orthographic projection of the display component on the cover plate. It can be seen that, relative to the related art, the frame size D1 of the watch in the embodiment of the present disclosure at least reduces the aforementioned avoidance spacing B and the partial width of the packaging structure (the adhesive layer in the related art and the package in the embodiment of the present disclosure are the packaging structure), thereby reducing the frame size D1 of the watch and increasing the proportion of the display area of ​​the watch.

[0082] In some embodiments, reference Figure 2 The watch also includes an adhesive layer 05, which is filled between the packaging member 04 and the middle frame 03. With the help of the adhesive layer, the watch can be more effectively packaged, and the installation firmness of the cover plate, the packaging member and the middle frame can be improved. However, it should be noted that the adhesive layer is not necessarily provided. In the case where the packaging member is directly formed between the cover plate and the middle frame by injection molding or other processes, the packaging member can directly seal the gap between the cover plate and the middle frame, and no adhesive layer is required.

[0083] Optionally, the package 04 is an injection molded part. The injection molded part here refers to a structure obtained by injection molding. Based on such a setting, the preparation accuracy of the package can be improved, and the matching degree between the package and adjacent components can be improved.

[0084] It should be noted that there are at least two ways to form the package in a watch: one is to directly use the cover plate and the display component as the basis, use an injection mold to form the package, and then assemble the structure formed with the package with the middle frame. In this case, an adhesive layer is generally required; the other is to first assemble the cover plate, the display component and the middle frame together, and then use the injection mold as the basis for injection molding to obtain a watch with the package. At this time, the package is in contact with the cover plate, the display component and the middle frame respectively, with no gap between them, and no additional adhesive layer is required.

[0085] Optionally, package 04 is a vacuum potted component. The vacuum potted component here refers to a structural component formed by means of a vacuum potting process. The vacuum potting process is an automatic glue filling operation method that ensures that the product is under absolute negative pressure. Specifically, the product is placed in a vacuum box, the air in the vacuum box is extracted, the vacuum box reaches a negative pressure state, and then the pre-prepared colloid is poured into the product. After the colloid is solidified, the product can be taken out, and the preparation of the package is completed. This method is conducive to further reducing the size of the package and reducing the size of the mobile phone frame.

[0086] In some embodiments, reference Figure 2 , the package 04 includes a first part 041, a second part 042 and a third part 043;

[0087] The first part 041 is located between the cover plate 01 and the middle frame 03, and the orthographic projection of the first part 041 on the cover plate 01 is staggered with the orthographic projection of the display component 02 on the cover plate 01; the second part 042 is located between the display component 02 and the cover plate 01, and the third part 043 is located between the display component 02 and the middle frame 03, and the first part 041 is connected to the second part 042 and the third part 043 respectively.

[0088] It should be noted that the display assembly may have multiple stacked layers, some of which may extend relative to other layers, so that the side of the display assembly as a whole has a drop, that is, has relative protrusions. Or the display assembly may have a main circuit board and a connecting circuit board, and the connecting circuit board (such as a flexible circuit board FPC) is electrically connected to the main circuit board from one or some layers of the display assembly to realize signal control of the aforementioned layers. The connecting circuit board passes through the side of the display assembly, so that the side of the display assembly has a local arched structure or a protruding portion. The second part may be located between the protruding portion and the cover plate, or between the arched structure and the cover plate. The third part may be directly located between a side of the display assembly away from the cover plate and the middle frame. The first part may be located at the periphery of the most convex point of the side of the display assembly (that is, the highest point of the aforementioned protruding portion or arched portion relative to the entire side). At least one of the first part, the second part and the third part may directly contact the surface of the display assembly. Here, the side of the display assembly is a surface that intersects or is perpendicular to the display surface of the display assembly.

[0089] The aforementioned “offset” means that there is no overlapping portion between the orthographic projection of the first portion 041 on the cover plate 01 and the orthographic projection of the display component 02 on the cover plate 01 .

[0090] In this embodiment, the second part of the package is actually in contact with the cover plate and the display assembly, filling the gap between the two and improving the assembly stability between the two; the third part is actually in contact with the display assembly and the middle frame, filling the gap between the two and improving the assembly stability between the two; and the first part is directly filled between the cover plate and the middle frame, and is connected to the second part and the third part respectively. With the cooperation of these three parts, the package can effectively encapsulate the cover plate, the display assembly and the middle frame on the one hand, and fully fill the gap in the watch on the other hand to prevent air from corroding the display assembly or the middle frame; on the other hand, it can act as a bracket to ensure that the cover plate is not easy to dent even if the watch is subjected to external force.

[0091] Optional, reference Figure 2 The third part 042 or the second part 043 extends along the extension direction of the display surface of the display assembly. In this way, the contact area between the second part or the third part and the adjacent components is larger, which is conducive to improving the sealing between the components and the assembly reliability.

[0092] In summary, in the watch provided by the embodiment of the present disclosure, the orthographic projection of the package on the cover plate at least partially overlaps with the orthographic projection of the display component on the cover plate, so that the effect of the package on the size of the watch frame is at least partially offset, the size of the watch frame is reduced, the proportion of the watch display area is increased, and the user experience is better. Furthermore, the package can also prevent air from corroding the display component or the middle frame, and act as a bracket to improve the watch's drop resistance.

[0093] On the other hand, the embodiment of the present disclosure provides a mold for injection molding a watch. Specifically, the mold can at least be used to injection mold the packaging part in the aforementioned watch.

[0094] In injection molding technology, an injection mold is generally required to clamp the basic structural parts or form a cavity of a specific shape, and then inject liquid material through the injection hole of the mold. After the liquid material solidifies, the mold can be removed to obtain the target structural parts for injection molding.

[0095] Injection molds are frequently pulled during repeated use, and the inner surface of molds made of certain materials may have problems such as bulging, bubbles, or breakage.

[0096] To ensure the accuracy of injection molding, the mold with the above problems needs to undergo a series of maintenance processes. During this period, the injection mold cannot be used normally, resulting in reduced production efficiency of the production line and high maintenance costs.

[0097] The mold for injection molding a watch provided by the embodiment of the present disclosure has high maintenance efficiency, high production efficiency, and high product surface accuracy. Figure 4-6 The injection mold comprises a first mold 1 and a second mold 2, wherein the first mold 1 is opposite to the second mold 2;

[0098] The first mold 1 includes a mold core 11 and a mold frame 12. The mold core 11 includes a mold core support 111 and a silicone structure 112 supported by the mold core support 111. The mold core support 111 is detachably mounted on the mold frame 12.

[0099] A pouring space x is formed between the silicone structure 112 and the second mold 2 .

[0100] In the injection mold provided by the embodiment of the present disclosure, the mold core and the mold frame of the first mold are detachably installed. When the mold core has problems during production, the mold core can be removed and replaced with a new mold core (the mold core can be pre-produced in batches and stored), so that production can be quickly resumed, which can effectively improve production efficiency and maintenance efficiency. At the same time, the mold core includes a mold core support and a silicone structural member. The mold core support can ensure that the overall rigidity of the mold core is high, and a pouring space is formed between the silicone structural member and the second mold. The surface of the product produced by the injection mold is smoother and flatter, so that the production accuracy of the product is better.

[0101] Exemplarily, when the above mold is used to injection mold the packaging of a watch, the process may include (taking the packaging formed on the cover plate and the display assembly first, and then assembling it with the middle frame as an example): placing the assembly structure of the cover plate and the display assembly between the first mold and the second mold, evacuating (an optional step), injecting liquid material through the first mold, waiting for solidification, separating the first mold and the second mold, and taking out the assembly structure with the packaging. The packaging obtained by the above process has a high degree of fit with the cover plate and the display assembly, and the surface is smooth and free of burrs.

[0102] In some embodiments, the silicone structure 112 is formed on the mold support 111 by injection molding. By using the injection molding process to form the silicone structure 112, the production cost of the mold can be lowered. Optionally, the hardness of the silicone structure can be controlled between 50A and 70A.

[0103] Optionally, the mold core bracket 111 is a plastic bracket. The plastic bracket can effectively improve the overall hardness of the mold core, ensure that the mold core does not deform during the production process, and thus ensure that the shape and size of the produced product are highly accurate. Optionally, the mold core bracket can be made of polycarbonate (PC) or polyamide (PA), which has low shrinkage performance and can control the dimensional tolerance of the mold core bracket within ±0.03mm.

[0104] In some embodiments, reference Figure 5 The first mold 1 further includes a reinforcing member 13, which reinforces the mold core bracket 111 and installs it on the mold frame 12. With the help of the reinforcing member, the installation stability and reliability of the entire mold core on the mold frame can be effectively ensured, thereby improving the stability and reliability of production.

[0105] Optional, combined Figure 5 and Figure 8 The mold frame 12 has a first limiting step 121 , the mold core support 111 has a second limiting step 1111 , and the first limiting step 121 abuts against the second limiting step 1111 .

[0106] Based on the above arrangement, the matching relationship between the mold frame and the mold core support can be more stable and reliable, and the mold frame and the mold core support can move as a whole.

[0107] Optional, combined Figure 5 and Figure 8 The mold support 111 has a first reinforcement surface 1112 , and the mold frame 12 has a second reinforcement surface 126 ; the side of the reinforcement member 13 close to the mold support 111 abuts against the first reinforcement surface 1112 and the second reinforcement surface 126 .

[0108] Based on the above arrangement, the reinforcement piece can simultaneously abut against the mold core support and the reinforcement surface of the mold frame, ensuring that the mold core support is always fixed relative to the mold frame in the presence of the reinforcement piece, thereby enhancing the installation stability of the mold core relative to the mold frame.

[0109] In some embodiments, in combination Figure 5 and Fig. 9 The reinforcement member 13 includes a pressing block 131 and a fastener 132 . The pressing block 131 is formed with a first fastening hole 1311 . The mold frame 12 is formed with a second fastening hole 122 . The fastener 132 is installed in the first fastening hole 1311 and the second fastening hole 122 .

[0110] With the help of the fasteners and the first fastening holes on the pressing block and the second fastening holes on the mold frame, the installation reliability of the pressing block or the reinforcement member as a whole relative to the mold frame can be effectively ensured, thereby ensuring the installation reliability of the mold core relative to the mold frame. It should be noted that the aforementioned "reinforcement member" against the first reinforcement surface or the second reinforcement surface refers to the pressing block against the first reinforcement surface or the second reinforcement surface.

[0111] Optionally, the fastener 132 is any one of a screw, a bolt or a screw. Here are only some examples, and those skilled in the art can also adjust the form of the fastener according to needs.

[0112] In some embodiments, the silicone structural member 112 is interference fit with the mold support 111. It should be noted that in this embodiment, the silicone structural member can be preformed. By setting the silicone structural member and the mold support to have an interference fit, the assembly firmness between the silicone structural member and the mold support can be effectively ensured. Optionally, the interference fit size here is 0.02 to 0.05 mm.

[0113] In some embodiments, in combination Fig.10 The mold core 11 has a first glue port 113 and a second glue port 114, and the first glue port 113 and the second glue port 114 are both connected to the injection space x. Of the first glue port 113 and the second glue port 114, one can be used to inject liquid, and the other can be used to overflow the liquid (it should be noted that the "glue" and "liquid" in this application can be liquid rubber or plastic, and are not limited to glue in a narrow sense). With the help of these two glue ports, it can be ensured that during the injection molding process, the injected liquid can overflow after filling the injection space without excessive accumulation, thereby improving the manufacturing accuracy of the product. Optionally, the first glue port and the second glue port can be located at two positions far apart from each other on the mold core, such as on a diagonal line, so as to ensure higher manufacturing accuracy of the product.

[0114] In some embodiments, in combination Fig.10 and Figure 4The mold core 11 has a first vent 115, and the mold frame 12 has a second vent 123, and the first vent 115 is connected to the second vent 123. With the help of the first vent and the second vent, it can be ensured that after the initial production of the product is completed, the product can be easily removed by blowing air through the first vent and the second vent, ensuring that the product is not easily deformed when removed.

[0115] In some embodiments, in combination Figure 4-6 , the mold frame 12 has a glue notch 124;

[0116] Combination Figure 11-13 The mold core 11 has a first gluing channel 116 and a second gluing channel 117, and the first gluing channel 116 and the second gluing channel 117 are respectively located in a gluing notch 124;

[0117] The first glue passage 116 is communicated with the first glue port 113 , and the second glue passage 117 is communicated with the second glue port 114 .

[0118] In this embodiment, the mold core has two gluing channels, each of which can be located in a gluing slot of the mold frame. During the injection molding process, the gluing channel in the gluing slot can be used to conveniently inject liquid or collect overflowed liquid, which is beneficial to improving the convenience of the injection molding process.

[0119] In some embodiments, in combination Figure 12-14 The mold frame 12 has a first limiting structure 125, and the mold core 11 has a second limiting structure 118. The first limiting structure 125 cooperates with the second limiting structure 118 to limit.

[0120] With the above arrangement, it can be further ensured that the mold frame and the mold core can be assembled quickly and accurately with the help of the cooperation between the first limiting structure and the second limiting structure, thereby improving the efficiency of injection mold maintenance.
