[0002] In the structural design of electronic equipment, button functions and indicator light functions are usually designed on the side of the housing of the electronic equipment.

[0003] In the button function, by pressing a button (such as the reset button), the pressing effect applied to the button is transmitted from the outside of the shell to the main board inside the shell, thereby achieving the control purpose of the button; in the indicator light function, the lighting effect on the main board inside the shell is guided to the outside of the shell through the light guide column, thereby achieving the light guiding purpose of the light guide column.

[0004] In practice, the inventors found that the following problems exist when assembling the above-mentioned structure: At present, the materials of the buttons and the light guide column are different, so the conventional practice is to make the buttons and the light guide column separately from the shell, and then assemble the manufactured buttons and light guide column with the shell respectively, so there are many assembly parts, the assembly process is complicated, and the production efficiency is low; since the light guide column is made of hard plastic material, it is necessary to use sealant between the light guide column and the shell for waterproofing. Because the sealant is injected into the side of the shell, the injection operation is difficult, and the glue is difficult to adapt to the harsh working environment, which directly affects the service life.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] In response to the problems existing in the prior art, the present application provides a composite insert, a shell and an electronic device. The technical solution of the present application mainly involves the structure of the composite insert, the structure of the shell, and the assembly relationship between the composite insert and the shell. The technical solution of the present application redesigns the above contents to achieve the purpose of reducing costs and simplifying the assembly process.

[0051] For composite inserts, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the composite insert provided in the embodiment of the present application. Figure 2 This is a schematic diagram of the structure of the key and light guide structure provided in the embodiment of the present application. Figure 3A schematic diagram of the structure of the reinforcement structure provided in an embodiment of the present application.

[0052] In a specific embodiment, the composite insert 1 provided in the embodiment of the present application is used to be assembled on the shell body 2, and the composite insert 1 includes a button and light-guiding structure 11 and a reinforcement structure 12. The button and light-guiding structure 11 have a button part 111 and a light-guiding part 112 with the same material. The button part 111 is used to transmit the pressing effect, and the light-guiding part 112 is used to guide the lighting effect. The hardness of the material used for the reinforcement structure 12 is greater than the hardness of the material used for the button and light-guiding structure 11. The reinforcement structure 12 is integrally formed with the button and light-guiding structure 11, and the reinforcement structure 12 is embedded in the button and light-guiding structure 11.

[0053] In the instructions for use of the composite insert 1, first, the composite insert 1 is assembled on the shell body 2, and then the main board 3 on the inner side of the shell body 2 is arranged corresponding to the buttons and light guide structure 11 of the composite insert 1. For example, the indicator light on the main board 3 is arranged at the light guide portion 112, and the button 31 on the main board 3 is arranged at the button portion 111; when in use, by pressing the button portion 111 on the outer side of the shell body 2, the pressing effect is transmitted from the button portion 111 to the button 31 on the main board 3, thereby realizing the function of the button 31, and through the lighting of the indicator light on the main board 3, the light guide portion 112 guides the lighting effect on the inner side of the shell body 2 to the outer side of the shell body 2, thereby realizing the indicator light function. In the processing instructions of the composite insert 1, because the hardness of the material used for the reinforcement structure 12 is greater than the hardness of the material used for the button part 111 and the light guide part 112, and the reinforcement structure 12 is integrally formed with the button and the light guide structure 11, and the reinforcement structure 12 is embedded in the interior of the button and the light guide structure 11, the appearance stability of the composite insert 1 can be effectively guaranteed, so that the soft material characteristics of the button and the light guide structure 11 can be used to form a waterproof seal with the shell body 2, and the problem of easy deformation of the button and the light guide structure 11 can be solved.

[0054] Combined with the above structure and process description, it can be seen that the composite insert 1 has at least the following beneficial effects: the composite insert 1 integrates the components of the button 31 function and the indicator light function into one part, and is assembled with the shell body 2 in the form of an insert, which reduces costs and simplifies the assembly process.

[0055] Optionally, for the material of the composite insert 1, the key and light guide structure 11 can be made of silicone, and the reinforcement structure 12 can be made of steel; in addition, other optional materials should also fall within the scope of the description of this embodiment.

[0056] In some cases, the composite insert 1 provided in the embodiment of the present application designs the traditional light guide column and the reset button as one part, so the composite insert 1 is equivalent to the silicone button light guide column, and the reinforcement structure 12 is equivalent to the reinforcement steel sheet. The raw material of the part is translucent silicone, and when the silicone mold is made, the reinforcement steel sheet is pre-embedded and integrally formed; in this way, the reinforcement steel sheet can effectively ensure the shape stability of the silicone button light guide column, overcoming the shortcomings of the silicone part being soft and easy to deform.

[0057] In order to better illustrate the beneficial effects of the composite insert 1 provided by the embodiment of the present application, the composite insert 1 is now compared with several related solutions in the prior art.

[0058] For existing technologies, electronic devices such as card machines will use indicator lights and reset buttons. Usually, the reset button and indicator light are on the side of the product. The design of the side indicator light usually uses a light guide to guide the light of the LED light on the motherboard to the surface of the product. For electronic devices with waterproof requirements, the sealing of the reset button and the light guide with the shell is very important.

[0059] As for the assembly and sealing methods of the light guide column and the shell, one is to adopt two-color injection molding, specifically, the light guide column is made of transparent material, and the shell is made of another material, and the two are integrally formed in the same mold, which can ensure that they are tightly combined together and have a good waterproof effect. However, the price of the two-color molding mold is high, the yield rate is low, and the cost will be high. The other is that the light guide column and the shell are made separately, and the light guide column is sealed and fixed to the inner wall of the shell through the glue dispensing groove reserved in the shell by glue dispensing, but the side wall glue dispensing is difficult to operate, and it is easy to overflow the glue, causing the glue to stick to the light guiding surface of the light guide column. In addition, the glue currently on the market cannot pass the high and low temperature, aging and other tests, and cannot adapt to various harsh working environments, which directly affects the service life.

[0060] Regarding the assembly and sealing methods of the reset button and the shell, one method is to use a metal sheet or a similar device to install it from the side, and use the shell structure to support the metal sheet so that the metal sheet and the side wall of the shell jointly compress the silicone reset button to achieve a waterproof function. This method is not easy to assemble because the side compression force is all applied, and screw locking is required, which increases the assembly process and time; another method is to use waterproof foam adhesive to fix the silicone button and the side wall of the front shell for waterproofing, but in this method, because the button will be subjected to force when used, the direction of this force is perpendicular to the adhesive plane, which will cause the adhesive to fall off over time, and the double-sided adhesive itself has poor adaptability to harsh environments such as high and low temperatures and outdoor environments, and its reliability is not good.

[0061] In combination with the contents of the above-mentioned prior art, it can be seen that the existing reset button and light guide column are generally made of different materials. The reset button is generally made of soft rubber material, and the light guide column is made of hard rubber material. The two-color injection molding of the light guide column is expensive, and the side wall gluing solution is not easy to operate and cannot adapt to some harsh working environments; the reset button requires an additional design structure to extrude waterproofing, which increases the assembly process and assembly difficulty. In response to these problems, the present application proposes a simple and feasible solution in which the reset button and the light guide column are used as inserts, which are then integrated with the shell after injection molding. This can reduce costs and simplify the assembly process. At the same time, since the reset button and the light guide column are made of the same material, the soft characteristics of silicone are used to improve the sealing and waterproofing effect.

[0062] It should be noted that the focus of the above embodiment is to define the structure of the composite insert 1, and there is no specific limitation on the assembly of the composite insert 1 and the shell body 2; that is to say, on the basis of the above embodiment, the assembly scheme of the composite insert 1 and the shell body 2 allows both assembly and one-piece molding such as injection molding, which should belong to the description scope of this embodiment.

[0063] Please continue to refer to Figure 2 In some embodiments, the button and light guide structure 11 further has a coupling portion 113 , which is disposed on the assembly surface 101 where the composite insert 1 and the shell body 2 cooperate, and is used to enhance the coupling strength between the composite insert 1 and the shell body 2 .

[0064] It should be noted that the present embodiment does not limit the specific structure of the coupling portion 113. Therefore, the specific structure of the coupling portion 113 allows for both a convex structure and a concave structure. As long as it is possible to enhance the bonding strength between the composite insert 1 and the shell body 2 by means of convex-concave matching when the composite insert 1 is assembled with the shell, and ensure the connection reliability and sealing, it should fall within the scope of the description of the present embodiment.

[0065] In some cases, taking the case where the button and light-guiding structure 11 are made of silicone, the reinforcement structure 12 is made of steel, and the composite insert 1 is integrally injection-molded with the shell as an example, in order to make the button and light-guiding structure 11 as an insert tightly combined with the shell to prevent it from falling off, a joint 113 is designed when the button and light-guiding structure 11 are molded, and then when the shell is molded, an anti-slip structure that cooperates with the joint 113 is formed on the shell. At this time, the joint 113 of the button and light-guiding structure 11 is firmly combined with the anti-slip structure of the shell, which can effectively prevent the button and light-guiding structure 11 from falling off, avoid loosening between the composite insert 1 and the shell body 2 when pressed, and ensure the reliability of waterproofing.

[0066] In some embodiments, the joint part 113 is arranged and protrudes on the surface of the composite insert 1 facing the shell body 2. It should be noted that the design of the joint part 113 is intended to enhance the bonding strength and sealing between the composite insert 1 and the shell body 2, and the number and setting position of the joint part 113 are not limited in this embodiment. These joint parts 113 can be evenly distributed or concentrated at key stress points, edge areas, or arranged at different positions of the composite insert 1 in a multi-point support manner, so as to achieve the purpose of enhancing the bonding strength and sealing between the insert 1 and the shell body 2 as a whole.

[0067] Please refer to Figures 4 to 6 , Figure 4 This is a cross-sectional structural diagram of the composite insert provided in the embodiment of the present application at the key position. Figure 5 This is a cross-sectional structural diagram of the composite insert provided in the embodiment of the present application at the light guide position. Figure 6 This is a cross-sectional structural diagram of a key and a light-guiding structure at the key position provided in an embodiment of the present application.

[0068] In a specific embodiment, Figure 4 and Figure 6 As shown, the button portion 111 includes a first connecting body 1111, a button body 1112 and a column 1113. The first connecting body 1111 is arranged around the button body 1112 and connected to the button body 1112, the first connecting body 1111 provides support for the button body 1112, the button body 1112 protrudes from the surface of the first connecting body 1111, the outer end surface of the button body 1112 plays a role in receiving pressure, the force-bearing end of the column 1113 is connected to the inner end surface of the button body 1112, the force-applying end of the column 1113 can abut against the button on the main board inside the shell body 2, and the column 1113 plays a role in transmitting the pressing effect on the button body 1112 to the button on the main board.

[0069] like Figure 4 As shown, the coupling portion 113 includes a first protrusion 1131 provided corresponding to the button portion 111 , or an annular protrusion 1132 provided corresponding to the button portion 111 , or both the first protrusion 1131 and the annular protrusion 1132 provided simultaneously.

[0070] As for the first protrusion 1131, the first protrusion 1131 is arranged on the first connector 1111, the first protrusion 1131 is a dovetail matching structure, and is in the shape of a barb with a narrow bottom and a wide top. A single first protrusion 1131 is arranged on the first connector 1111 along the axial extension of the button portion 111, and a plurality of first protrusions 1131 are distributed around the circumference of the button portion 111 on the first connector 1111. When the composite insert 1 is combined with the shell body 2, the first protrusion 1131 on the first connector 1111 is used to enhance the bonding strength between the composite insert 1 and the shell body 2.

[0071] The annular protrusion 1132 is arranged on the outer circumferential surface of the button body 1112. A single annular protrusion 1132 is arranged on the outer circumferential surface of the button body 1112 in a circumferential direction of the button portion 111. A plurality of annular protrusions 1132 are distributed at intervals along the axial direction of the button portion 111 on the outer circumferential surface of the button body 1112. When the composite insert 1 is combined with the shell body 2, the annular protrusion 1132 on the outer circumferential surface of the button body 1112 enhances the combination strength of the composite insert 1 and the shell body 2. It should be noted that, because the first protrusion 1131 and the annular protrusion 1132 are structures arranged at different positions of the button portion 111, when the composite insert 1 is combined with the shell body 2, an anti-slip structure that cooperates with the first protrusion 1131 and the annular protrusion 1132 is formed on the shell, and a multi-position combination scheme is formed at the same time, thereby further enhancing the bonding strength and sealing between the insert 1 and the shell body 2, thereby enhancing the bonding strength between the composite insert 1 and the shell body 2 by concave-convex matching in different directions, thereby ensuring the connection reliability and sealing.

[0072] like Figure 5 As shown, the coupling portion 113 includes a second protrusion 1133 arranged corresponding to the light guide portion 112. The structure and arrangement of the second protrusion 1133 are similar to those of the first protrusion 1131. The second protrusion 1133 is in the shape of a hook with a narrow bottom and a wide top. A single second protrusion 1133 is arranged on the circumference of the light guide portion 112 and extends along the axial direction of the light guide portion 112. A plurality of second protrusions 1133 are distributed circumferentially around the circumference of the light guide portion 112. By so arranging, an anti-slip structure that cooperates with the second protrusion 1133 is formed on the shell, thereby enhancing the structural strength of the composite insert 1 and the shell body 2 through a concave-convex matching method.

[0073] Please continue to refer to Figure 3 In some embodiments, the reinforcement structure 12 has a first positioning hole 121 , and the first positioning hole 121 is used to realize the positioning of the reinforcement structure 12 when the reinforcement structure 12 is integrally formed with the key and the light guide structure 11 .

[0074] In this embodiment, when the composite insert 1 is integrally formed, the reinforcement structure 12 is positioned in the silicone mold by using the first positioning hole 121 to achieve pre-embedding of the reinforcement structure 12, and then the composite insert 1 can be integrally formed, thereby ensuring the accuracy of part molding.

[0075] Furthermore, the button and light guide structure 11 also has a second positioning hole 114 that matches the first positioning hole 121 , and the second positioning hole 114 is used to achieve positioning of the composite insert 1 when the composite insert 1 is assembled with the shell body 2 .

[0076] In this embodiment, after the integral molding of the composite insert 1 is completed, a second positioning hole 114 cooperating with the first positioning hole 121 is formed on the button and the light-guiding structure 11. When the shell is integrally molded, the second positioning hole 114 is used, which is similar to the positioning of the reinforcement structure 12. Here, the second positioning hole 114 is used for positioning with the oblique pin in the shell mold, thereby realizing the positioning of the composite insert 1 and ensuring the accuracy of the position of the composite insert 1.

[0077] Please continue to refer to Figures 4 to 6 , and refer to Figure 7 , Figure 7 This is a cross-sectional structural diagram of the key and light guide structure provided in an embodiment of the present application at the light guide position.

[0078] In some embodiments, the reinforcement structure 12 has a first reinforcement portion 122 disposed corresponding to the button portion 111 and a second reinforcement portion 123 disposed corresponding to the light guide portion 112 , and the first reinforcement portion 122 and the second reinforcement portion 123 are integrally formed.

[0079] Corresponding to the button portion 111, the reinforcement structure 12 is provided with a first reinforcement portion 122 inside the first connecting body 1111, and the first connecting body 1111 is formed with a first mounting groove 11111 for the first reinforcement portion 122 to be embedded in. Optionally, the first reinforcement portion 122 is annular, and the first mounting groove 11111 is an annular groove. After the first reinforcement portion 122 is embedded in the first mounting groove 11111, it surrounds the circumference of the column 1113 in a surrounding form and at a certain interval.

[0080] like Figure 5 and Figure 7 As shown, the light guide portion 112 includes a second connector 1121 and a light guide 1122. The second connector 1121 is disposed around the light guide 1122 and connected to the light guide 1122. The second connector 1121 provides support for the light guide 1122. The outer end of the light guide 1122 leads to the outside, and the inner end of the light guide 1122 can lead to the LED light on the main board inside the shell body 2. The light guide 1122 plays a light-guiding role in guiding the light effect inside the shell body 2 to the outside of the shell. Corresponding to the light guiding portion 112, the reinforcement structure 12 is provided with a second reinforcement portion 123 inside the second connecting body 1121, and the second connecting body 1121 is formed with a second mounting groove 11211 for the second reinforcement portion 123 to be embedded in; as an option, the second reinforcement portion 123 is annular, and the second mounting groove 11211 is an annular groove, and after the second reinforcement portion 123 is embedded in the second mounting groove 11211, it surrounds the circumference of the light guiding portion 112 in a surrounding form and at a certain interval.

[0081] It should be noted that, since the button portion 111 and the light guide portion 112 are an integrally formed structure, a third connector is formed between the first connector 1111 and the second connector 1121 for connection; for a plurality of light guide portions 112, a fourth connector is formed between the plurality of light guide portions 112 for connection; and for a plurality of button portions 111, a fifth connector is formed between the plurality of button portions 111 for connection.

[0084] In this embodiment, the composite insert 1 is assembled into one with the shell body 2; optionally, the composite insert 1 is used to be integrally molded with the shell body 2; in some cases, the composite insert 1 and the shell body 2 are injection molded; with such a configuration, on the one hand, the integral molding of the composite insert 1 and the shell body 2 can reduce costs and simplify the assembly process, and on the other hand, because of the integral molding, the waterproof reliability can be greatly improved, which is suitable for various working environments.

[0085] Please continue to refer to Figure 8 And refer to Fig.11 and Fig.12 , Fig.11 This is a schematic diagram of the structure of the combination of the shell and the composite insert provided in the embodiment of the present application. Fig.12 This is an assembly structure diagram of the combination provided in an embodiment of the present application from another perspective.

[0086] In a specific embodiment, the present application further provides a housing, including a housing body 2 and the composite insert 1, the side of the housing body 2 has a key and light guide assembly position 21, the key and light guide assembly position 21 is installed with the composite insert 1, and the composite insert 1 is assembled with the housing body 2. The housing should have all the beneficial effects of the composite insert 1, which will not be repeated here.

[0087] It should be noted that the shell body 2 shown in the figure is a front shell, which is equivalent to a half of a complete shell. The assembly method of the complete shell belongs to the existing technology and will not be repeated here.

[0088] Please refer to Fig. 9 and Fig.10 ,and Fig.13 and Fig.14 , Fig. 9 This is a cross-sectional structural diagram of the housing at the key position provided in an embodiment of the present application. Fig.10 This is a cross-sectional structural diagram of the housing provided in the embodiment of the present application at the light guide position. Fig.13 A cross-sectional structural diagram of the combination provided in the embodiment of the present application at the key position, Fig.14 A cross-sectional structural diagram of the assembly provided in an embodiment of the present application at the light guiding position.

[0089] like Fig. 9 As shown, on the side of the shell body 2, the button and light guide assembly position 21 includes a first bayonet 211 corresponding to the first protrusion 1131, and an annular groove 212 corresponding to the annular protrusion 1132. When the shell is formed, the first protrusion 1131 will be embedded in the first bayonet 211, and the annular protrusion 1132 will be embedded in the annular groove 212, which can effectively prevent the composite insert 1 from falling off. Even if an inward pressing force is applied to the composite insert 1 during use, due to the existence of the above-mentioned anti-slip matching structure, it will not cause looseness between the composite insert 1 and the shell body 2, and the reliability of waterproofing is well guaranteed.

[0090] like Fig.10 As shown, on the side of the shell body 2, the button and light guide assembly position 21 includes a second bayonet 213 corresponding to the second protrusion 1133. When the shell is formed, the second protrusion 1133 will be embedded in the second bayonet 213, which also prevents the composite insert 1 from falling off, avoids loosening between the composite insert 1 and the shell body 2, and ensures the reliability of waterproofing.

[0091] In some embodiments, the outer surface of the shell body 2 is flush with the outer surface of the composite insert 1, and the outer surfaces of the shell body 2 and the composite insert 1 are all painted except the light guide portion 112. In actual operation, by only shielding the light guide portion 112, the outer surfaces of the shell body 2 and the composite insert 1 are all exposed to the painting range except the light guide portion 112, and then the painting operation is performed, so that the outer surfaces of the shell body 2 and the composite insert 1 are all painted except the light guide portion 112.

[0092] In this embodiment, before the shell is injected, the composite insert 1 is placed as a separate part in the injection mold for making the shell body 2. At this time, the second positioning hole 114 can still be used as a positioning hole, and positioned with the oblique pin in the shell mold to ensure the accuracy of the position of the composite insert 1; when the shell body 2 is injected, the second positioning hole 114 is supported by the structure on the oblique pin of the injection mold, and supports the inner wall, so that the outer surface of the button part 111 and the light guide part 112 contact the mold core wall of the mold, forming a slight compression, so that after the injection molding is completed, the outer surface of the composite insert 1 can be guaranteed to be in the same plane as the outer surface of the shell body 2. When spraying the shell surface, the button part 111 and the shell body 2 can be easily sprayed together to ensure the integrated effect of the appearance and avoid the color difference problem existing in the separate production method.
