[0063] In the related art, the material of the terminal structure can affect the appearance, weight, structural strength and manufacturing cost of the terminal device, and the connection scheme and process of different parts of the terminal structure during the assembly process are also related to its manufacturing cost. Therefore, it is difficult for the terminal structure in the related art to take into account the requirements of appearance texture, lightness and cost.

[0064] The present disclosure provides a terminal structural component, which is applied to terminal equipment. Figure 1 is a schematic diagram of a terminal structure in an exemplary embodiment of the present disclosure, such as Figure 1As shown, the terminal structure 1 includes a first part 11 and a second part 12. The first part 11 includes a first structural layer 111 and a second structural layer 112 stacked, the first structural layer 111 faces the outside of the terminal device, and the second structural layer 112 faces away from the outside of the terminal device. The connection area of ​​the second part 12 is seamlessly connected with the second structural layer 112 to form a continuous whole with the first part 11.

[0065] The first part 11 of the terminal structure 1 includes a first structural layer 111 and a second structural layer 112 which are stacked, so that the expected appearance and weight can be obtained by combining the properties of the first structural layer 111 and the second structural layer 112. The terminal structure 1 also includes a second part 12, and the connection area of ​​the second part 12 is seamlessly connected with the first part 11 to form a continuous whole, so it can be applied to conventional process equipment, which helps to simplify the process flow and reduce manufacturing costs.

[0066] Since the first part 11 includes a first structural layer 111 and a second structural layer 112 which are stacked, it is different from the connection scheme between a structural member of a single material and the second part 12, so that the terminal structural member 1 needs to redevelop a fixture and change the process flow during the process of the first part 11 and the second part 12, resulting in increased costs. The connection area of ​​the second part 12 of the present disclosure is seamlessly connected with the first part 11 and is used as a whole for subsequent processes, so it can adapt to the original process equipment, which helps to reduce costs and simplify the process flow.

[0067] It should be noted that the first part 11 involved in the present disclosure may be a frame, a back cover, a functional component, and other devices of the terminal device, and the second part 12 may be a structural member such as a middle plate, a bracket, and a reinforcement member that needs to be connected to the first part 11 to meet structural and process requirements. The following is an exemplary description of the terminal structural member 1 with the first part 11 as the frame and the second part 12 as the middle plate:

[0068] In some embodiments, the frame is a continuous frame structure, which can be directly connected to the middle plate before use, reducing the material connection process for each part of the frame itself, which helps to simplify the process flow. The middle plate can be provided with connection areas at positions corresponding to the four sides of the frame structure to achieve seamless connection with the frame structure and ensure connection reliability.

[0069] In other embodiments, the frame may include at least two interconnected substructures, and the shape of the substructure includes at least one of a U-shape, an I-shape, and an L-shape, so as to reduce the difficulty of forming the frame. At the same time, when the frame is required to be used as an antenna radiator, the antenna segmentation requirements can be adapted through its own structure. For example, a plate may include three substructures, namely Figure 2 The U-shaped Figure 3 Type I shown and Figure 4 In the L-shaped structure shown, three substructures of different shapes are formed into a frame structure through a material connection process. Similarly, the middle plate can be provided with connection areas at positions corresponding to the four sides of the frame structure to achieve seamless connection with the frame structure and ensure connection reliability.

[0070] The material of the middle plate can be aluminum or magnesium, so as to reduce the overall weight of the terminal structure 1 by selecting the material of the middle plate, while ensuring the functional requirements of the terminal structure 1. It should be noted that when the second part 12 is other parts of the terminal structure 1, the material of the second part 12 can also be other materials such as metal and plastic, and the present disclosure is not limited to this.

[0071] Since the first part 11 includes the first structural layer 111 and the second structural layer 112, different material selection schemes can be formed according to its structure and function. The material scheme of the first part 11 is exemplarily described below:

[0072] In some embodiments, the first structure layer 111 is an integrated structure of the same material. Since the first structure layer 111 faces the outside of the terminal device, the integrated first structure layer 111 of the same material can obtain a consistent appearance.

[0073] In this embodiment, the material of the first structural layer 111 may include one of stainless steel, titanium alloy, copper alloy, and aluminum alloy to obtain a metallic texture appearance effect.

[0074] In other embodiments, the first structural layer 111 includes at least two interconnected first structural sections, and the materials of the at least two first structural sections are different. The first structural sections of different materials enable the first structural layer 111 to form different appearance effects, which helps to enrich the external aesthetics of the terminal device.

[0075] In this embodiment, the material of the first structural section may include at least one of stainless steel, titanium alloy, copper alloy, and aluminum alloy to obtain different metallic texture appearance effects.

[0076] In some embodiments, the second structural layer 112 is an integrated structure of the same material. Since the second structural layer 112 has structural support and conductive connection functions, selecting an integrated structure of the same material can improve the reliability of conductive connection and structural strength.

[0077] In this embodiment, the material of the second structure layer 112 may include at least one of stainless steel, titanium alloy, copper alloy, and aluminum alloy. For example, the material of the second structure layer 112 may be aluminum.

[0078] In other embodiments, the second structural layer 112 includes at least two interconnected second structural sections, and the materials of the at least two second structural sections are different. The second structural sections of different materials enable the second structural layer 112 to obtain a support effect of expected strength in a specific area and form a directional conductive connection effect.

[0079] It should be noted that when the first structural layer 111 includes at least two first structural divisions, the connection between the two first structural divisions can be achieved by welding, riveting, pressing, injection molding, etc. Similarly, when the second structural layer 112 includes at least two second structural divisions, the connection between the two second structural divisions can be achieved by welding, riveting, pressing, injection molding, etc.

[0080] In some embodiments, the material of the first structural layer 111 includes one of stainless steel, titanium alloy, copper alloy, and aluminum alloy, and the material of the second structural layer 112 includes one of stainless steel, titanium alloy, copper alloy, and aluminum alloy, and the materials of the first structural layer 111 and the second structural layer 112 are different. Since the first structural layer 111 and the second structural layer 112 are exposed to the terminal device and are mainly used to achieve the appearance effect, and the second structural layer 112 is located inside the first structural layer 111 and is mainly used to achieve the support and conductive connection functions, selecting suitable materials for the first structural layer 111 and the second structural layer 112 based on the functional difference between the first structural layer 111 and the second structural layer 112 can ensure the realization of their respective functions and also help reduce the overall weight of the terminal structural component 1.

[0081] In some embodiments, the inner side surface of the second structural layer 112 facing away from the first structural layer 111 is provided with a connecting protrusion 1121, and the connecting protrusion 1121 is conductively connected to the second part 12. The connecting protrusion 1121 can extend relative to the inner side surface of the second structural layer 112 in structure, which helps to achieve conductive connection with the middle plate or other devices. The connecting protrusion 1121 can directly contact with the second part 12 to achieve conductive connection, or can achieve conductive connection through a spring, a connector, a connecting wire, etc., which can be selected according to specific needs, and the present disclosure is not limited to this.

[0082] In some embodiments, in the stacking direction of the first structure layer 111 and the second structure layer 112, the height of the connecting protrusion 1121 is greater than the thickness of the second structure layer 112. The height of the connecting protrusion 1121 is greater than the thickness of the second structure layer 112, which can ensure the structural strength of the first part 11 and the realization of the conductive connection function.

[0083] The second structural layer 112 and the connecting protrusion 1121 may be an integrated structure to simplify the process of setting the connecting protrusion 1121 and improve the structural strength of the connecting protrusion 1121, thereby improving the reliability of the conductive connection.

[0084] In the above embodiment, the thickness of the first structural layer 111 is greater than or equal to 0.5 mm and less than or equal to 3 mm, so as to avoid the first structural layer 111 being too thin and causing the appearance interface to be exposed when the molding process of the first structural layer 111 is realized. And / or, the thickness of the second structural layer 112 is less than or equal to 8 mm, so as to ensure the function of the second structural layer 112 and the realization of the molding process.

[0085] In the above embodiment, the connection area of ​​the second part 12 and the second structural layer 112 are seamlessly joined through the metallurgical bonding structure 13, so that the connection area of ​​the second structural layer 112 and the second part 12 forms a gapless connection, thereby improving the sealing and reliability of the connection.

[0086] The metallurgical bonding structure 13 may cover the connection area to further increase the connection reliability.

[0087] Furthermore, the thickness of the metallurgical bonding structure 13 may be greater than or equal to 1.5 mm to ensure the metallurgical bonding process is achieved while ensuring the connection strength.

[0088] It should be noted that the metallurgical bonding structure 13 includes one of a welding structure, a riveted structure and an injection molding structure. When the metallurgical bonding structure 13 is a welding structure, the welding process may be laser welding, friction welding (such as stir friction welding), ultrasonic welding, etc.

[0089] In some embodiments, the terminal structural component 1 may further include at least one filling structure, which is formed in the interval space between the first part 11 and the second part 12 to fill the space between the first part 11 and the second part 12, thereby improving the overall structural strength and sealing performance of the terminal structural component 1 and reducing the mass of the terminal structural component 1.

[0090] The filling structure can be an injection molding structure, with glue filling and sealing between the filling structure and the first part 11, and glue filling and sealing between the filling structure and the second part 12. The glue filling and sealing further increase the sealing effect of the terminal structure 1, supporting the waterproof effect of the terminal device to reach IP68.

[0091] It should be noted that before injection molding the filling structure, the surface of the first part 11 and / or the second part 12 in contact with the filling part can be T-treated to form nano-voids to enhance the connection strength between the first part 11 and the second part 12 of the injection molding structure.

[0092] In some embodiments, the volume of a single filling structure is less than or equal to 1750 mm 3 , in order to comprehensively consider the structural divisions of various regions of the terminal structural member 1 and ensure the flame retardant performance of the terminal structural member 1.

[0093] The present disclosure further provides a terminal device, which includes the terminal structure 1 mentioned above.

[0094] Since the first part 11 of the terminal structure 1 includes the first structure layer 111 and the second structure layer 112 stacked, the expected appearance and weight can be obtained by combining the properties of the first structure layer 111 and the second structure layer 112. Among them, the connection area of ​​the second part 12 of the terminal structure 1 is seamlessly connected with the first part 11 to form a continuous whole, so it can be applied to conventional process equipment, which helps to simplify the process flow and reduce manufacturing costs.

[0095] It should be noted that the above-mentioned terminal device can be a mobile phone, a tablet computer, a vehicle-mounted terminal, a medical terminal, a wearable device, etc., and the present disclosure does not limit this.

[0096] The present disclosure further provides a method for processing a terminal structure part 1 , which is used for processing the terminal structure part 1 . Figure 5 is a flow chart of a method for processing a terminal structure 1 in an exemplary embodiment of the present disclosure, such as Figure 5 As shown, the above method can be implemented by the following steps:

[0097] In step S501 , a first portion 11 including a first structure layer 111 and a second structure layer 112 is formed.

[0098] In some embodiments, forming the first part 11 including the first structure layer 111 and the second structure layer 112 may be: pressing the first structure layer 111 and the second structure layer 112 into a pressed structure, and bending and / or forging the pressed structure to obtain the first part 11.

[0099] In some embodiments, the first part 11 includes at least two substructures, and bending and / or forging the pressed structure to obtain the first part 11 can be: bending and / or forging the pressed structure to obtain the substructure, and connecting the substructures to form the first part 11. Connecting the substructures after forming can reduce the difficulty of forming the frame, and at the same time, when the frame is needed to be used as an antenna radiator, it can adapt to the antenna segmentation requirements through its own structure. For example, the plate can include three substructures, namely U-shaped, I-shaped, and L-shaped, and the three shapes of substructures are formed into a frame structure through a connecting process. Similarly, the middle plate can be provided with connection areas at positions corresponding to the four sides of the frame structure, so as to achieve seamless connection with the frame structure and ensure the reliability of the connection.

[0100] In some embodiments, before seamlessly joining the connection area of ​​the second part 12 to the second structural layer 112 to form a continuous whole with the first part 11 , the method further includes: obtaining the second part 12 by machining and / or die casting.

[0101] In step S502 , the connection area of ​​the second portion 12 is seamlessly joined to the second structural layer 112 to form a continuous whole with the first portion 11 .

[0102] Since the first part 11 of the terminal structure 1 includes the first structure layer 111 and the second structure layer 112 stacked, the expected appearance and weight can be obtained by combining the properties of the first structure layer 111 and the second structure layer 112. Among them, the connection area of ​​the second part 12 of the terminal structure 1 is seamlessly connected with the first part 11 to form a continuous whole, so it can be applied to conventional process equipment, which helps to simplify the process flow and reduce manufacturing costs.

[0103] In some embodiments, the connection area of ​​the second portion 12 is seamlessly joined to the second structural layer 112 to form a continuous whole with the first portion 11. The method may be:

[0104] The connection area of ​​the second part 12 is seamlessly joined to the second structural layer 112 through the metallurgical bonding structure 13 to form a continuous first whole with the first part 11, the first whole is machined to obtain a connector, a filling structure is formed in the space between the first part 11 and the second part 12 in the connector to obtain a second whole, and the second whole is machined to obtain the terminal structural part 1.

[0105] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
