DETAILED DESCRIPTION

[0044] In the related art, a smartwatch usually has a bottom shell and an upper shell for mounting a display screen, and a mounting support structure for mounting a speaker is formed on the bottom shell. The bottom shell is usually processed by one-time injection molding, and the bottom wall thickness of the mounting support structure is relatively large. When the bottom shell is injection molded, the bottom wall position of the mounting support structure is prone to shrinkage and stress marks, which affects the yield rate of the bottom shell.

[0045] In view of this, the embodiment of the present application provides a wearable device and a shell processing device thereof, wherein the processing device is used to form a primary molded part by one injection molding, wherein the primary molded part includes at least an inner layer component, and the inner layer component is configured to support the first functional part of the wearable device; then the primary molded part is used as an inlay for secondary injection molding to form the shell of the wearable device. Such a setting not only does not change the structure of the shell, but also molds the thicker wall position in the shell twice, thereby solving the problems of shrinkage and stress marks and improving the yield rate of the shell.

[0046] Furthermore, the one-time molded part also includes a heart rate lens. When the heart rate lens is formed, the inner layer component is simultaneously formed by injection molding without adding additional steps, thereby ensuring the production efficiency of the shell.

[0047] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0048] The embodiment of the present application provides a wearable device, which includes a wearable device housing 110. Figure 1 and Figure 2 The wearable device housing 110 of the embodiment of the present application includes a housing body and a second functional component 130 disposed on the housing 110, and the second functional component 130 is fixedly connected to the wearable device housing 110. A support structure 111 is also formed on the housing 110 for mounting a first functional component 120 of the wearable device, such as a speaker. The wearable device of the embodiment of the present application may be a smart watch, a smart bracelet, a smart wristband, etc.

[0049] It should be noted that the wearable device housing 110 can be the bottom housing of the device or the upper housing of the device, and this embodiment of the present application does not limit this. For areas where the upper wall thickness of the housing 110 is relatively large and there are shrinkage and stress marks in the one-time molding, the secondary injection molding method in the embodiment of the present application can be used to improve the shrinkage and stress marks, so as to improve the yield rate of the housing.

[0050] In the embodiment of the present application, the second functional component 130 may be a heart rate lens, and three second functional components 130 are arranged side by side, and the three second functional components 130 are injection molded at the same time. Of course, this does not limit the number of the second functional components 130.

[0051] The support structure 111 is a rounded rectangular groove structure in the drawings, but this does not limit the shape and structure of the support structure 111. In the drawings, the housing 110 is roughly rounded rectangular, but this does not limit the shape of the housing 110.

[0052] Combination Figure 2 and Figure 3 The support structure 111 is in the shape of a groove, which includes a bottom wall and a side wall. The bottom wall of the support structure 111 is relatively thick. During the one-time injection molding process, there is more liquid injection material in the bottom wall area. During the cooling molding process, it is easy to shrink due to stress, and stress marks appear on the appearance, affecting the yield of the shell 110.

[0053] To this end, the embodiment of the present application uses a two-time injection molding method to process and shape the support structure 111. Specifically, Figure 4 and Figure 6 First, a primary molded part is formed using a first molding die 10 , wherein the primary molded part at least includes an inner layer component 112 .

[0054] In some examples, the once-molded component further includes a second functional component 130 . Thus, the inner layer component 112 is formed simultaneously with the process of molding the second functional component 130 , thereby avoiding adding additional processes and ensuring production efficiency.

[0055] The inner layer component 112 of the embodiment of the present application includes a bottom wall portion and a side wall portion that are connected. This not only facilitates molding, but also allows the thicker side walls of the support structure 111 to be injection molded twice, thereby avoiding shrinkage and stress marks on the side walls.

[0056] Then, the primary molded part is placed as an inlay in the second molding die 20, and the housing 110 is formed by the second molding die 20, thereby forming a complete support structure 111. This arrangement not only does not change the structure of the housing 110, but also molds the thicker part of the support structure 111 in the housing 110 twice, thereby solving the problems of shrinkage and stress marks and improving the yield rate of the housing 110.

[0057] The specific structure and function of the first molding die 10 and the second molding die 20 in the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0058] The embodiment of the present application also provides a wearable device shell processing device for forming the above-mentioned wearable device shell.

[0059] The wearable device shell processing device of the embodiment of the present application includes an injection device, a first molding mold 10 and a second molding mold 20. The injection device injects molding material into the first molding mold 10 to form a primary molded part; the injection device injects molding material into the second molding mold 20 to form a secondary molded part.

[0060] The first molding die 10 includes a lower half mold 200 and a first upper half mold 300 , and the second molding die 20 includes a lower half mold 200 and a second upper half mold 400 .

[0061] The lower mold 200 may be provided with a first upper mold 300 and a second upper mold 400 which are alternately combined with the lower mold 200 to alternately form a first molding mold 10 and a second molding mold 20 , and perform primary injection molding and secondary injection molding alternately.

[0062] In the embodiment of the present application, two lower half molds 200 are provided, and the two lower half molds 200 are detachably connected to the first upper half mold 300 and the second upper half mold 400, respectively, and the detachable connection method can be a threaded connection, etc. In this way, the first molding mold 10 and the second molding mold 20 exist at the same time, and the primary injection molding and the secondary injection molding are performed at the same time, which is conducive to improving production efficiency.

[0063] The processing device of the embodiment of the present application also includes a flipping mechanism, which is fixedly connected to the two lower half molds 200; the flipping mechanism is constructed to drive the two lower half molds 200 to rotate 180° when the first upper half mold 300 is separated from the lower half mold 200 and the second upper half mold 400 is separated from the lower half mold 200, so as to exchange the lower half molds 200 fixed with the first upper half mold 300 and the second upper half mold 400, and perform primary injection molding and secondary injection molding respectively.

[0064] The following is a detailed description with reference to the accompanying drawings. Figure 4 In the first molding die 10 shown in FIG. Figure 6 The second molding die 20 shown in the figure has a primary molding part embedded therein, and a secondary injection molding is performed; after the molding is cooled, the attached Figure 4 The first upper half mold 300 is separated from the lower half mold 200, and the Figure 4 The lower half mold 200 has a primary molded part; and Figure 5 The second upper mold 400 and the lower mold 200 are removed and the attached Figure 5 The housing 110 formed by the second molding die 20; the flip mechanism drives the fixed Figure 4 The lower half mold 200 and Figure 5 The lower half mold 200 in the middle rotates 180°; at this time, the attached Figure 5 The lower half mold 200 and the attached Figure 4 The first upper half mold 300 in the mold is formed into a first molding mold 10, and a single injection molding is performed; Figure 4 The lower half mold 200 and the attached Figure 5 The second upper half mold 400 in the second molding die 20 is formed for secondary injection molding. In this way, primary injection molding and secondary injection molding are performed simultaneously, thereby improving the production efficiency of the housing.

[0065] In the embodiment of the present application, cooling channels are respectively provided in the lower half mold 200, the first upper half mold 300 and the second upper half mold 400. The cooling channels are used to pass coolant to reduce the temperature of the molding mold, facilitate cooling and molding of the injection molded parts, and help further improve production efficiency.

[0066] Continue to refer to Figure 4 and Figure 5 The first upper mold 300 is matched and connected with the lower mold 200 to form a one-time molding chamber together. The one-time molding chamber at least includes an inner layer component chamber, which is constructed as an inner layer component 112 of the injection molding shell, wherein the inner layer component 112 is used to support the first functional part in the wearable device, such as a speaker.

[0067] Continue to refer to Figure 6 and Figure 7 The lower half mold 200 molded with the inner layer component is matched and connected with the second upper half mold 400 to form a secondary molding cavity together, and the secondary molding cavity is constructed to be an injection molded wearable device shell.

[0068] like Figure 6 and Figure 7 As shown, a slide groove is also provided at the joint between the lower half mold 200 and the second upper half mold 400, and a slider 440 is inserted into the slide groove to cooperate with the molding mold to form a concave structure of the shell.

[0069] Through the above-mentioned one-shot molding and two-shot molding, the support structure 111 with a thicker wall is processed and molded twice, which effectively avoids the shrinkage and stress mark problems caused by one-shot molding and improves the yield rate of the shell.

[0070] In an embodiment of the present application, the one-time molding chamber also includes a functional component chamber, which is configured to injection mold a second functional component 130 of the wearable device; wherein the second functional component 130 is fixedly connected to the wearable device housing.

[0071] Through the above arrangement, the second functional part 130 and the inner layer component 112 can be injection molded simultaneously in one molding chamber, thus avoiding the need for additional steps and ensuring the production efficiency of the shell.

[0072] In some specific implementations, the functional component chamber is configured to be a transparent functional component of the wearable device, such as a heart rate lens, for injection molding. In this way, the inner layer component 112 and the heart rate lens are molded at the same time without changing the injection molding material, which is conducive to ensuring the production efficiency of the shell.

[0073] In some possible implementations, the inner component chamber is constructed to form an inner support structure of the shell, for example, the inner support structure is used to support the first functional part, and the first functional part can be supported without additional machining on the shell.

[0074] In the embodiment of the present application, the first upper mold 300 is provided with a first injection channel 301 and a second injection channel 302, the first injection channel 301 is connected to the inner layer component cavity, and the second injection channel 302 is connected to the functional component cavity. After the injection device injects the injection molding material into the functional component cavity through the second injection channel 302, and injects the injection molding material into the inner layer component cavity through the first injection channel 301, and after cooling, the second functional component 130 is injection molded in the functional component cavity, and the inner layer component 112 is injection molded in the inner layer component cavity. The second functional component 130 and the inner layer component 112 are primary molded parts, which are placed in the lower mold 200 as inserts for secondary injection molding.

[0075] A third injection channel 401 connected to the secondary molding chamber is formed on the second upper mold 400. After the injection device injects the injection material toward the secondary molding chamber through the third injection channel 401 and cools, the secondary molding chamber injection molds the wearable device shell.

[0076] In some possible embodiments, the first upper mold 30 and the lower mold 200 together form a primary molding chamber; the second upper mold 400 and the lower mold 200 together form a secondary molding chamber, so that a shell can be molded at one time. In this way, the molding mold is simple and the injection runner design is simple.

[0077] In some other possible implementations, the first upper mold 300 and the lower mold 200 are enclosed together to form a plurality of primary molding cavities. For example, the plurality of primary molding cavities are arranged at intervals along a set direction (e.g., a length direction) of the first upper mold 300; the second upper mold 400 and the lower mold 200 are enclosed together to form a plurality of secondary molding cavities. The number of the secondary molding cavities is the same as the number of the primary molding cavities, and the arrangement position of the secondary molding cavities is the same as the arrangement position of the primary molding cavities. In this way, the lower mold 200 can be shared or exchanged. With such an arrangement, multiple shells can be molded at one time, which is conducive to improving the production efficiency of the shells.

[0078] In some specific implementations, the multiple primary molding cavities are centrally symmetrically distributed about the center of the lower mold 200; the multiple secondary molding cavities are centrally symmetrically distributed about the center of the lower mold 200; of course, the second injection channel 302, the first injection channel 301, and the third injection channel 401 are centrally symmetrically distributed about the center of the lower mold 200. With such an arrangement, when the two lower molds 200 are flipped using the flip mechanism, injection can be achieved without changing the injection equipment, which is conducive to improving production efficiency.

[0079] In the embodiment of the present application, the first upper mold 300 and the lower mold 200 are enclosed together to form two primary molding chambers, and the two primary molding chambers are centrally symmetrically distributed about the center of the lower mold 200; the second upper mold 400 and the lower mold 200 are enclosed together to form two secondary molding chambers, and the two secondary molding chambers are centrally symmetrically distributed about the center of the lower mold 200. With such a configuration, two shells can be injection molded at the same time, and the mold can be prevented from being too complicated and resulting in high mold opening costs.

[0080] The structures and functions of the first upper mold half 300 , the second upper mold half 400 and the lower mold half 200 are respectively introduced below with reference to the accompanying drawings.

[0081] like Figure 4 and Figure 5 As shown, the first upper mold 300 includes a first mold body 310 and a first insert, and a first groove 311 is provided on the side of the first mold body 310 facing away from the lower mold 200, and a second injection channel 302 and a first injection channel 301 are provided on the bottom wall of the first groove 311. In the drawings, the first groove 311 is a rectangular groove, which is not a limitation on the shape of the first groove 311.

[0082] A first embedding hole 312 is provided on the bottom wall of the first groove 311, and the first insert can be matched and installed in the first embedding hole 312. In this way, the first insert and the first embedding hole 312 cooperate with the first mold body 310 and the lower half mold 200 to form a closed inner layer component cavity.

[0083] The embodiment of the present application provides a first insert, which, on the one hand, helps to simplify the mold structure and facilitate mold processing; on the other hand, the tiny gap between the first insert and the first embedding hole 312 helps to discharge gas when injecting the injection molding material, avoids the formation of bubbles in the injection molded part, and helps to improve the injection molding quality and injection molding efficiency.

[0084] Combination Figure 8 and Fig. 9In the embodiment of the present application, the cross-sectional shape of the first inlay hole 312 is rectangular, and the first inlay hole 312 has two first hole walls 3121, which are opposite to each other along the first direction and have a gap; a part of one of the first hole walls 3121 protrudes toward the other first hole wall 3121 to form a protrusion 313. The first injection channel 301 can be disposed on the protrusion 313. The cross-sectional shape of the protrusion 313 can be rectangular.

[0085] Correspondingly, the first insert has a recessed portion matching the protrusion 313. Through the cooperation between the protrusion 313 and the recessed portion, it not only has an anti-error function, but also helps to guide the first insert to be installed into the first embedding hole 312 or taken out from the first embedding hole 312, thereby improving the convenience of disassembly and assembly of the first insert.

[0086] Continue to refer to Figure 8 and Fig. 9 A limiting platform 314 is provided in the first inlay hole 312, the limiting platform 314 protrudes toward the first inlay hole 312, and the limiting platform 314 is located on the side of the protruding portion 313. Optionally, two limiting platforms 314 can be provided, and the two limiting platforms 314 are provided on both sides of the protruding portion 313 along the second direction, wherein the second direction is perpendicular to the first direction. There is a gap between the two limiting platforms 314 to facilitate the first insert to pass through. Correspondingly, a step portion matching the limiting platform 314 is provided on the first insert.

[0087] In the embodiment of the present application, a limiting platform 314 is provided, and the limiting platform 314 abuts against the step portion of the first insert to play a limiting role, so as to limit the position of the first insert inserted into the first embedding hole 312.

[0088] In the embodiment of the present application, the inner layer component chamber includes a first cavity and a second cavity that are connected, the first cavity is perpendicular to the axial direction of the first embedding hole 312, the second cavity is located at the edge of the first cavity, and the second cavity is perpendicular to the first cavity; the outlet end of the first injection channel 301 is located in the first cavity. Figure 3 The first cavity is used for injection molding to form the bottom wall of the inner layer component 112, and the second cavity wall is used for injection molding to form the side wall of the inner layer component 112. Such a configuration not only facilitates the molding of the inner layer component 112, and the molding of the housing 110 when used as an insert; moreover, the outlet end of the first injection channel 301 is located in the first cavity, and the layout space is sufficient.

[0089] like Fig. 9 As shown, an annular wall 315 is provided on the side of the first mold body 310 of the first upper mold 300 facing the lower mold 200, and the lower mold 200 has a gap with the first mold body 310 and the first insert to form a first cavity; the lower mold 200 is partially recessed and abuts against the annular wall 315 to form a second cavity.

[0090] In the embodiment of the present application, the shape of the annular wall 315 matches the shape of the step surface of the support structure 111. The annular wall 315 is an open annular wall, which facilitates the molding of the internal structure of the support structure 111. The embodiment of the present application facilitates the molding of the inner layer component 112 by providing the annular wall 315, which helps to simplify the structure of the mold.

[0091] In some possible implementations, the outlet end of the first injection channel 301 is located at the center of the inner component cavity. Such a configuration facilitates the balance of liquid injected into the inner component cavity, thereby helping to improve the injection molding quality.

The second insert, the first mold body 310 and the lower mold 200 are jointly enclosed to form a functional component cavity.

[0093] Such a configuration not only helps to simplify the mold structure and facilitate mold processing, but also the tiny gap between the second insert and the second embedding hole 316 helps to discharge gas when injecting the injection molding material, avoids the formation of bubbles in the injection molding part, and helps to improve the injection molding quality and injection molding efficiency.

[0094] Of course, a limiting structure is provided in the second embedding hole 316 , and the limiting structure abuts against the step structure of the second embedding component to play a limiting role, so as to limit the position of the second embedding component inserted into the second embedding hole 316 .
