Description

Technical Field

[0001] This application relates to the field of terminal equipment, and in particular to a frame assembly and a terminal device. Background Technology

[0002] As competition intensifies in the consumer electronics market, terminal devices are not only pursuing functional innovation but also focusing on personalized appearance design. Taking mobile phones as an example, to enhance the visual appeal and texture of the product, decorative parts are set on the mid-frame of the phone. These decorative parts enhance the phone's appearance and recognition, meeting the differentiated needs of consumers.

[0003] In related technologies, a separate assembly space is provided in order to fix the decorative parts on the middle frame and achieve waterproofing.

[0004] However, the setup of this assembly space has the problem of complex structure and occupies internal space of the middle frame. Utility Model Content

[0005] This application provides a frame assembly and a terminal device. It solves the problems of complex structure and low space utilization of the fixed decorative parts on the middle frame in the prior art. The technical solution is as follows:

[0006] In one aspect, a frame assembly is provided, including: a middle frame, decorative parts, and connectors;

[0007] The middle frame has a decorative groove, which has slots and bottoms that are oppositely distributed in a first direction, and the slots are located on the outer surface of the middle frame;

[0008] At least a portion of the decorative element is located within the decorative groove, and the side of the decorative element away from the bottom of the groove is exposed through the groove opening;

[0009] One side of the connector is connected to the side of the decorative piece facing the bottom of the groove, and the other side of the connector is connected to the bottom of the groove;

[0010] The first direction is perpendicular to the outer surface of the middle frame where the slot is formed.

[0011] Because decorative grooves are formed in the middle frame, with the groove openings and bottoms distributed along a first direction, and the groove openings located on the outer surface of the groove, a connector connects to the side of the decorative element facing the bottom of the groove on one side in the first direction, and to the bottom of the groove on the other side. Thus, when installing a decorative element within the groove, at least a portion of the decorative element and the connector can be placed within the groove through the grooves distributed on the outer surface of the groove in the first direction, and the connection between the groove and the decorative element is achieved through the connector. This effectively simplifies the fixing structure and process of the decorative element and frees up internal space in the middle frame in the first direction. When the internal space of the middle frame in the first direction is freed up or increased, the utilization rate of the internal space of the middle frame or the stacking efficiency can be improved.

[0012] In some possible implementations, one side of the connector is bonded to the side of the decorative element facing the bottom of the groove, and the other side of the connector is bonded to the side of the bottom of the groove facing the decorative element.

[0013] The connector uses adhesive bonding to secure the decorative elements within the decorative groove. This facilitates installation and fixation of the decorative elements within the groove. Furthermore, the connector can have a smaller size in the first direction, meaning it occupies less space there, thus freeing up internal space in the middle frame and improving space utilization. Additionally, the connector's simple structure facilitates manufacturing and reduces production costs for frame components including decorative elements.

[0014] In some possible implementations, the middle frame also has an opening communicating with the decorative groove, and in the first direction, the opening is located on the side of the groove bottom facing away from the groove opening;

[0015] The connector is fixedly connected to the decorative piece on the side facing the bottom of the groove, and the connector is snapped into the inner surface of the middle frame after passing through the opening.

[0016] By fixing one side of the connector to the decorative element facing the bottom of the decorative groove, and the other side of the connector passing through the opening and engaging with the inner surface of the middle frame, the connection strength between the connector and the middle frame at the bottom of the decorative groove can be improved, thus ensuring the reliability of the connection between the connector and the middle frame. Furthermore, since the connector is also fixedly connected to the decorative element, the improved reliability of the connection between the connector and the middle frame also improves the reliability of the connection between the decorative element and the middle frame. Therefore, even under extreme conditions such as drops or impacts, the connection reliability between the decorative element and the middle frame of the terminal device using this frame assembly can be guaranteed.

[0017] In some possible implementations, the connector includes: a first connector and a second connector; the first connector extends along the first direction, and both ends of the first connector in the first direction are respectively connected to the side of the decorative element facing the bottom of the groove and the second connector, and the extension direction of the second connector intersects the first direction;

[0018] The second connector passes through the opening and engages with the inner surface of the middle frame, and at least a portion of the first connector is located within the opening.

[0019] The first connector in the connector facilitates the connection between the decorative part and the second connector, while the second connector and the inner surface of the middle frame can be interlocked to achieve an indirect connection between the decorative part and the middle frame. This ensures the connection strength and reliability between the decorative part and the middle frame.

[0020] In some possible implementations, the opening is a strip-shaped hole, the extension direction of which intersects with the first direction, and after the second connector is engaged with the inner surface of the middle frame, the extension direction of the strip-shaped hole intersects with the extension direction of the second connector.

[0021] By adjusting the angle between the extension direction of the second connector and the extension direction of the strip hole, so that the extension direction of the second connector intersects with the extension direction of the strip hole, a snap-fit ​​can be achieved between the second connector and the inner surface of the middle frame, thereby achieving a snap-fit ​​between the decorative part and the middle frame at the decorative groove. Furthermore, by adjusting the angle between the extension direction of the second connector and the extension direction of the strip hole, so that the extension direction of the second connector is parallel to the extension direction of the strip hole, the snap-fit ​​between the second connector and the inner surface of the middle frame can be released, thereby achieving separation of the decorative part from the middle frame at the decorative groove. This allows for the replacement or maintenance of the decorative parts on the middle frame, enhancing the flexibility of the frame components and improving the user experience.

[0022] In some possible implementations, the width of the strip hole is greater than the width of the first connector in the target direction and greater than the width of the second connector in the target direction;

[0023] After the second connector engages with the inner surface of the middle frame, the target direction intersects with the extension direction of the second connector and with the first direction.

[0024] The extension length of the second connector is greater than the width of the strip hole.

[0025] The width of the strip hole is greater than the width of the first connector in the target direction and greater than the width of the second connector in the target direction, so that at least a portion of the first connector can be placed in the strip hole, and the second connector can pass through the strip hole and be located on the inner surface side of the middle frame.

[0026] The extension length of the second connector is greater than the width of the strip hole, so that at least one end of the second connector on the inner surface of the middle frame can be engaged with the inner surface of the middle frame in its extension direction.

[0027] In some possible implementations, the middle frame has a storage groove on its inner surface at the location of the opening; the storage groove communicates with the decorative groove through the opening, and the portion of the connector that engages with the inner surface of the middle frame is located within the storage groove.

[0028] The storage slot provides a certain installation space for the second connector, which can protect the second connector at this location and ensure the reliability of the snap-fit ​​between the second connector and the middle frame. This also avoids interference from other surrounding components on the snap-fit ​​between the second connector and the inner surface of the middle frame.

[0029] In some possible implementations, in the first direction, the dimension of the portion of the connector located within the receiving groove is less than or equal to the depth of the receiving groove.

[0030] By ensuring that the size of the portion of the connector located within the storage slot is less than or equal to the depth of the storage slot, the connector within the storage slot can be more effectively protected. This ensures the reliability of the connection between the connector within the storage slot and the middle frame at this location, and avoids interference from other surrounding components on the connection between the connector within the storage slot and the inner surface of the middle frame.

[0031] In some possible implementations, the frame assembly further includes a seal; the seal is sandwiched between the decorative element and the decorative groove.

[0032] By using a sealant sandwiched between the decorative element and the decorative groove, the sealing of the space between the outer wall of the decorative element and the decorative groove can be ensured, thus providing better dust and water protection.

[0033] In some possible implementations, the seal is sandwiched between the outer wall of the decorative element and the side wall of the decorative groove, and / or, the seal is sandwiched between the side of the decorative element facing the bottom of the groove and the bottom of the groove.

[0034] In some possible implementations, the seal is sandwiched between the outer wall of the decorative element and the side wall of the decorative groove, and the outer wall of the decorative element has an annular sealing groove, a portion of the seal is embedded and fixed in the annular sealing groove, and another portion of the seal abuts against the side wall of the decorative groove.

[0035] The annular sealing groove can limit and fix the sealing element, ensuring the clamping position of the sealing element between the decorative element and the decorative groove, and also helping to ensure the sealing effect.

[0036] In some possible implementations, the inner surface of the middle frame has a wiring groove extending in a second direction, the wiring groove communicating with the decorative groove in the first direction;

[0037] The first direction and the second direction intersect; the wiring groove is used to install connecting wires.

[0038] Connecting cables can be installed through the wiring trough. The wiring trough connects to the decorative groove in the first direction, and an inspection port can be formed at the connection point. This inspection port can be used to check the sealing of the decorative parts fixed in the decorative groove, thus ensuring the processing quality of the frame components.

[0039] In some possible implementations, the decorative element includes: a decorative support and a decorative body;

[0040] At least a portion of the decorative bracket is fixed within the decorative groove, the decorative bracket has a mounting groove on the side away from the bottom of the groove, and the decorative bracket is connected to the connector on the side facing the bottom of the groove.

[0041] At least a portion of the decorative body is fixed within the mounting groove.

[0042] In a second aspect, a terminal device is provided, comprising: a frame assembly, a battery cover, and a display screen; the frame assembly is any of the frame assemblies described above;

[0043] The battery cover and the display screen are respectively connected to the two sides of the middle frame that are opposite to each other. Attached Figure Description

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0057] In related technologies, decorative parts fixed on the middle frame of the frame assembly are usually provided with independent assembly space in order to achieve waterproofing, and the setting of this space occupies the installation space inside the middle frame.

[0058] Taking mobile phones as an example, when the assembly space for installing decorative parts on the middle frame occupies internal space, it will affect some components installed inside the phone, such as reducing the volume that can be used to install the battery, thereby affecting the phone's battery life.

[0059] In addition, the structure of the decorative parts fixed on the middle frame is complex, requiring the use of components such as pins, and tools are needed for assembly, which not only increases the installation process but also increases production costs.

[0060] Based on this, embodiments of this application provide a frame assembly suitable for terminal devices and a terminal device including the frame assembly, which simplifies the structure of the fixed decorative parts on the middle frame, improves space utilization, simplifies the installation process, and reduces production costs.

[0061] Figure 1 This is a structural schematic diagram of a frame component provided in an embodiment of this application. Please refer to it. Figure 1 In one embodiment of this application, a frame component 000 is provided, including: a middle frame 010, a decorative component 020, and a connector 030.

[0062] The middle frame 010 has a decorative groove C1, which has a groove opening and a groove bottom that are relatively distributed in a first direction, and the groove opening is located on the outer surface of the middle frame 010.

[0063] At least a portion of the decorative element 020 is located within the decorative groove C1, and the side of the decorative element 020 away from the bottom of the groove is exposed through the groove opening.

[0064] One side of connector 030 is connected to the side of decorative part 020 facing the bottom of the groove, and the other side of connector 030 is connected to the bottom of the groove.

[0065] Among them, the first direction is perpendicular to the outer surface of the middle frame 010, where the groove is set.

[0066] It is understood that at least a portion of the decorative element 020 is located within the decorative groove C1, and the side of the decorative element 020 away from the bottom of the groove C1 is exposed through the groove opening. Specifically, a portion of the decorative element 020 may be located within the decorative groove C1, with the side of the decorative element 020 away from the bottom of the groove protruding from the groove opening and thus exposed. Alternatively, the entire decorative element 020 may be located within the decorative groove C1, in which case the side of the decorative element 020 away from the bottom of the groove C1 is also located within the decorative groove C1, meaning that the side of the decorative element 020 away from the bottom of the groove is exposed and visible, but does not protrude from the groove opening relative to the decorative groove C1.

[0067] It should be noted that, Figure 1 The frame component 000 shown illustrates a partial middle frame 010 structure. The complete structure of the middle frame 010, as exemplified, can be referenced. Figure 2 , Figure 2 This is a schematic diagram of the structure of a middle frame provided in an embodiment of this application.

[0068] like Figure 2As shown, the middle frame 010 includes: a first frame 011, a second frame 012, a third frame 013, and a fourth frame 014. Among them, the first frame 011 and the third frame 013 are opposite to each other and spaced apart, and the second frame 012 and the fourth frame 014 are opposite to each other and spaced apart.

[0069] The first frame 011, the second frame 012, the third frame 013, and the fourth frame 014 are connected end to end to form a rectangular frame. The space inside this rectangular frame can be used to install other components of the corresponding terminal device 100, such as a battery. At this time, the outer surface of the middle frame 010 is also the outer sidewall of the middle frame 010, and correspondingly, the inner surface of the middle frame 010 can be the inner sidewall of the middle frame 010.

[0070] For example, a decorative piece 020 is fixed on the first frame 011 in the middle frame 010, at which time the first direction is... Figure 2 In the horizontal direction, i.e., the width direction, a decorative groove C1 is formed on the middle frame 010. The opening and bottom of the decorative groove C1 are distributed along the first direction. The opening of the decorative groove C1 is distributed on the outer surface of the decorative groove C1. The connector 030 connects to the decorative part 020 on one side of the first direction, facing the bottom of the decorative groove C1, and to the bottom of the decorative groove C1 on the other side. Thus, when installing the decorative part 020 in the decorative groove C1, it can be fixed only by installing it in the first direction. This effectively simplifies the fixing structure and process of the decorative part 020 and frees up the internal space of the middle frame 010 in the first direction. When the internal space of the middle frame 010 in the first direction is freed up or increased, the utilization rate of the internal space of the middle frame 010 can be improved. For example, larger components can be fixed in the middle frame 010, or more components can be installed, improving stacking efficiency. Among them, a larger component is fixed inside the middle frame 010, for example, a battery with a larger size in the first direction is fixed inside the middle frame 010, thereby improving the battery life of the terminal device 100 using the frame assembly 000.

[0071] For example, a decorative piece 020 can also be fixed to the second frame 012 in the middle frame 010, in which case the first direction is... Figure 2 The vertical direction, that is, the length direction.

[0072] It should be noted that, in the embodiments of this application, decorative elements 020 and structures corresponding to the decorative elements 020 (such as decorative grooves C1 and connectors 030) can be provided on one or more of the first frame 011, the second frame 012, the third frame 013 and the fourth frame 014 in the middle frame 010. The number of decorative elements 020 on a certain frame can be one or more, which can be set according to actual needs, and this application does not impose any restrictions.

[0073] In summary, by creating decorative grooves on the middle frame, with the groove openings and bottoms distributed along a first direction, and the groove openings located on the outer surface of the groove, and by connecting the connector on one side of the decorative element facing the bottom of the groove in the first direction, and the other side connecting to the bottom of the groove, when installing the decorative element within the groove, at least a portion of the decorative element and the connector can be placed within the groove through the grooves distributed on the outer surface of the groove in the first direction, and the connection between the decorative groove and the decorative element can be achieved through the connector. This effectively simplifies the fixing structure and process of the decorative element and frees up the internal space of the middle frame in the first direction. When the internal space of the middle frame in the first direction is freed up or increased, the utilization rate of the internal space of the middle frame or the stacking efficiency can be improved.

[0074] Figure 3 This is a schematic diagram of another frame component provided in an embodiment of this application. Please refer to it. Figure 3 In some possible implementations, one side of the connector 030 is bonded to the side of the decorative part 020 facing the bottom of the decorative groove C1, and the other side of the connector 030 is bonded to the side of the groove bottom facing the decorative part 020.

[0075] At this time, the connector 030 can be a sheet-like or plate-like adhesive, and the connector 030 is located in the decorative groove C1, between the side of the decorative part 020 facing the bottom of the decorative groove C1 and the side of the bottom of the decorative groove C1 facing the decorative part 020.

[0076] The connector 030 uses adhesive bonding to secure the decorative part 020 within the decorative groove C1. This facilitates the installation and fixation of the decorative part 020 within the groove C1. Furthermore, the connector 030 can have a smaller size in the first direction, meaning it occupies less space there, thus freeing up internal space in the middle frame 010 and improving space utilization. Additionally, the connector 030 has a simple structure, is easy to manufacture, and reduces the production cost of the frame assembly 000 including the decorative part 020.

[0077] Figure 4 This is a structural schematic diagram of another frame component provided in an embodiment of this application. Please refer to it. Figure 4 In some other possible implementations, the middle frame 010 also has an opening K1 communicating with the decorative groove C1, and in the first direction, the opening K1 is located on the side of the groove bottom away from the groove opening.

[0078] Among them, the connector 030 is fixedly connected to the decorative part 020 on the side facing the bottom of the groove, and the connector 030 is snapped into the inner surface of the middle frame 010 after passing through the opening K1.

[0079] One side of the connector 030 is fixedly connected to the decorative part 020 facing the bottom of the decorative groove C1, and the other side of the connector 030 passes through the opening K1 and engages with the inner surface of the middle frame 010. This improves the connection strength between the connector 030 and the middle frame 010 at the bottom of the decorative groove C1, thereby ensuring the connection reliability between the connector 030 and the middle frame 010. Furthermore, since the connector 030 is also fixedly connected to the decorative part 020, the improved connection reliability between the connector 030 and the middle frame 010 also improves the connection reliability between the decorative part 020 and the middle frame 010. Thus, even under extreme conditions such as drops or impacts, the terminal device 100 using this frame assembly 000 can ensure the connection reliability between the decorative part 020 and the middle frame 010.

[0080] Figure 5 This is a schematic diagram of another frame component provided in an embodiment of this application. Please refer to it. Figure 5 In some possible implementations, the connector 030 includes a first connector 031 and a second connector 032. The first connector 031 extends along a first direction, and its two ends in the first direction are respectively connected to the side of the decorative piece 020 facing the bottom of the groove and the second connector 032. The extension direction of the second connector 032 intersects the first direction.

[0081] The second connector 032 passes through the opening K1 and engages with the inner surface of the middle frame 010, and at least a portion of the first connector 031 is located inside the opening K1.

[0082] For example, the first connector 031, the second connector 032, and the decorative part 020 are integrated into one structure. This facilitates the production and processing of the frame assembly 000 and ensures the connection strength between the first connector 031 and the decorative part 020 and the second connector 032 respectively.

[0083] The first connector 031 in connector 030 facilitates the connection between decorative part 020 and second connector 032. The second connector 032 is engaged with the inner surface of middle frame 010, which enables an indirect connection between decorative part 020 and middle frame 010. This ensures the connection strength and reliability between decorative part 020 and middle frame 010.

[0084] In some possible implementations, the opening K1 is a strip-shaped hole K11. Please refer to [reference needed]. Figure 6 , Figure 6This is a schematic diagram of the structure of a connector in a frame assembly in a first state according to an embodiment of this application. At this time, the extension direction of the strip hole K11 intersects with the first direction, and the extension direction of the second connector 032 also intersects with the first direction. That is, at this time, the extension direction of the strip hole K11 and the extension direction of the second connector 032 are parallel.

[0085] Please refer to Figure 7 , Figure 7 This is a structural schematic diagram of a connector in a frame assembly in a second state, provided in an embodiment of this application.

[0086] At this time, the extension direction of the strip hole K11, the first direction, and the extension direction of the second connector 032 intersect each other. For example, the extension direction of the strip hole K11, the first direction, and the extension direction of the second connector 032 are perpendicular to each other.

[0087] by Figure 5 For example, at this time, the decorative part 020 and the connector 030 fixedly connected to the decorative part 020 are located outside the decorative groove C1. When installing the decorative part 020, along... Figure 5 The first direction moves towards the side closer to the middle frame 010, and at least a portion of the decorative piece 020 is placed in the decorative groove C1, while the second connector 032 of the connector 030 passes through the opening K1 and is located on the inner surface of the middle frame 010. (This can be referenced at this time.) Figure 6 The extension direction of the second connecting body 032 in connector 030 is parallel to the extension direction of the opening K1. Next, rotate the decorative part 020 90°, and connector 030 and decorative part 020 rotate synchronously. The extension direction of the second connecting body 032 in connector 030 is perpendicular to the extension direction of the opening K1. At this point, refer to... Figure 7 The second connector 032 is engaged with the inner surface of the middle frame 010.

[0088] If the user wants to replace the decorative part 020 later, the user can rotate the decorative part 020 in the opposite direction or continue to rotate it 90° so that the extension direction of the second connector 032 in the connector 030 is parallel to the extension direction of the opening K1. At this time, the decorative part 020 can be pulled outward along the first direction to release the snap-fit ​​relationship between the second connector 032 and the middle frame 010.

[0089] It is understood that the rotation angle of the decorative part 020 here is only an illustrative example. The decorative part 020 can also be rotated to other angles, as long as the extension direction of the second connector 032 intersects with the extension direction of the opening K1, so as to achieve the snap-fit ​​between the second connector 032 and the inner surface of the middle frame 010.

[0090] By adjusting the angle between the extension direction of the second connector 032 and the extension direction of the strip hole K11, so that the extension direction of the second connector 032 intersects with the extension direction of the strip hole K11, a snap-fit ​​can be achieved between the second connector 032 and the inner surface of the middle frame 010, thereby achieving a snap-fit ​​between the decorative part 020 and the middle frame 010 at the decorative groove C1. Furthermore, by adjusting the angle between the extension direction of the second connector 032 and the extension direction of the strip hole K11, so that the extension direction of the second connector 032 is parallel to the extension direction of the strip hole K11, the snap-fit ​​between the second connector 032 and the inner surface of the middle frame 010 can be released, thereby achieving separation of the decorative part 020 from the middle frame 010 at the decorative groove C1. This allows for the replacement or maintenance of the decorative part 020 on the middle frame 010, enhancing the usability of the frame assembly 000 and improving the user experience.

[0091] Please refer to Figure 6 In some possible implementations, the width of the strip hole K11 is greater than the width of the first connector 031 in the target direction, and also greater than the width of the second connector 032 in the target direction. For example, the extending direction of the second connector 032 can be parallel to the extending direction of the strip hole K11.

[0092] Please refer to Figure 7 After the second connector 032 engages with the inner surface of the middle frame 010, the target direction intersects the extension direction of the second connector 032 and also intersects with the first direction. For example, the target direction is perpendicular to the extension direction of the second connector 032 and also perpendicular to the first direction.

[0093] The extension length of the second connector 032 is greater than the width of the strip hole K11.

[0094] The width of the strip hole K11 is greater than the width of the first connector 031 in the target direction and greater than the width of the second connector 032 in the target direction, so that at least a portion of the first connector 031 can be placed in the strip hole K11, and the second connector 032 can pass through the strip hole K11 and be located on the inner surface side of the middle frame 010.

[0095] The extension length of the second connector 032 is greater than the width of the strip hole K11, so that at least one end of the second connector 032 on one side of the inner surface of the middle frame 010 in its extension direction can be engaged with the inner surface of the middle frame 010.

[0096] For example, the width of the first connector 031 and the width of the second connector 032 can be the same, which facilitates the processing and manufacturing of the first connector 031 and the second connector 032.

[0097] The two ends of the second connector 032 in its extension direction can be symmetrically distributed about the first connector 031. That is, in the extension direction of the second connector 032, the middle part of the first connector 031 and the second connector 032 are fixedly connected. In this way, the second connector 032 can be engaged with the inner surface of the middle frame 010 at both ends. This can improve the engagement strength between the second connector 032 and the middle frame 010, thereby improving the connection strength between the decorative part 020 and the middle frame 010.

[0098] Please refer to Figure 7 In some possible implementations, the middle frame 010 has a storage groove C2 on its inner surface at the location of the opening K1. The storage groove C2 is connected to the decorative groove C1 through the opening K1, and the part of the connector 030 that engages with the inner surface of the middle frame 010 is located within the storage groove C2.

[0099] The storage slot C2 provides a certain installation space for the second connector 032, which can protect the second connector 032 at this location. This ensures the reliability of the snap-fit ​​between the second connector 032 and the middle frame 010 at this location and avoids interference from other surrounding components on the snap-fit ​​between the second connector 032 and the inner surface of the middle frame 010.

[0100] For example, in the first direction, the size of the portion of the connector 030 located within the storage groove C2 is less than or equal to the depth of the storage groove C2. That is, the side of the second connector 032 in the connector 030 facing away from the first connector 031 can be flush with the groove opening of the storage groove C2 on the inner surface of the middle frame 010, or the side of the second connector 032 in the connector 030 facing away from the first connector 031 can be recessed within the storage groove C2.

[0101] By ensuring that the size of the portion of connector 030 located within the storage slot C2 is less than or equal to the depth of the storage slot C2, connector 030 within the storage slot C2 can be more adequately protected. This ensures the reliability of the engagement between connector 030 and the middle frame 010 within the storage slot C2, and prevents interference from other surrounding components on the engagement between connector 030 and the inner surface of the middle frame 010 within the storage slot C2.

[0102] As mentioned earlier, since the connector 030 includes a first connector 031 and a second connector 032 connected to each other, the second connector 032 in the connector 030 is located in the storage groove C2, and it can be understood that the inner surface of the middle frame 010 that is engaged with the second connector 032 is also the bottom of the storage groove C2.

[0103] In other feasible embodiments, the opening K1 can also be a non-strip-shaped hole, such as a circular hole. Correspondingly, the first connecting body 031 is a circular rod, and the second connecting body 032 is a cone or frustum. The radial dimension of the second connecting body 032 decreases continuously from the side closer to the first connecting body 031 to the side away from the first connecting body 031.

[0104] The radial dimension of the circular rod is smaller than that of the circular hole, the maximum radial dimension of the second connector 032 is larger than that of the circular hole, and the second connector 032 is a cone or frustum made of a deformable material (e.g., silicone).

[0105] In this way, after the second connector 032 is squeezed and deformed through the circular hole, the second connector 032 recovers its deformation, thus achieving the snap-fit ​​connection with the inner surface of the middle frame 010.

[0106] In some possible implementations, the frame assembly 000 further includes a seal 040. The seal 040 is sandwiched between the decorative element 020 and the decorative groove C1.

[0107] By using the sealing element 040 sandwiched between the decorative element 020 and the decorative groove C1, the sealing of the space between the outer wall of the decorative element 020 and the decorative groove C1 can be ensured, thus providing better dust and water protection.

[0108] For example, a waterproof layer is provided on both the side of the seal 040 near the decorative part 020 and the side near the decorative groove C1. For instance, waterproof adhesive is applied to both the side of the seal 040 near the decorative part 020 and the side near the decorative groove C1 to form a waterproof layer, which further enhances the waterproof effect at the seal 040.

[0109] In some possible implementations, the seal 040 is sandwiched between the outer wall of the decorative element 020 and the side wall of the decorative groove C1, and / or, the seal 040 is sandwiched between the side of the decorative element 020 facing the bottom of the groove and the bottom of the groove.

[0110] When the sealing element 040 is sandwiched between the decorative element 020 on the side facing the bottom of the groove and the bottom of the groove, the sealing element 040 can be located at the outer periphery of the connector 030. In this way, the connector 030 can be avoided while the sealing effect can be achieved. For example, the sealing element 040 is a silicone sealing gasket.

[0111] Figure 8 This is a structural schematic diagram of a frame component provided in another embodiment of this application. Figure 8 Connector 030 in the middle corresponds to Figure 3 030 is an adhesive-bonded connector. Figure 9 This is a schematic diagram of another frame component provided in another embodiment of this application. Figure 9 Connector 030 in the middle corresponds to Figure 4 030 is a type of connector with a card-type connection.

[0112] Please refer to Figures 8-9 In some possible implementations, the seal 040 is sandwiched between the outer wall of the decorative element 020 and the side wall of the decorative groove C1, and the outer wall of the decorative element 020 has an annular sealing groove C3. A part of the seal 040 is embedded and fixed in the annular sealing groove C3, and another part of the seal 040 abuts against the side wall of the decorative groove C1.

[0113] The annular sealing groove C3 can limit and fix the sealing element 040, ensuring the clamping position of the sealing element 040 between the decorative element 020 and the decorative groove C1, and also helping to ensure the sealing effect.

[0114] Please refer to Figures 8-9 In one feasible implementation, the middle frame 010 includes: a first-layer frame P1, a second-layer frame P2, and a third-layer frame P3.

[0115] The second frame P2 can be a plastic frame, positioned between the first frame P1 and the second frame P2. The first frame P1 and the third frame P3 can be metal frames.

[0116] Correspondingly, the decorative groove C1 on the middle frame 010 can penetrate at least the first frame P1 and the second frame P2. For example, the decorative groove C1 penetrates the first frame P1 and the second frame P2, the opening of the decorative groove C1 is located on the outer surface of the first frame P1, and the bottom of the decorative groove C1 is located on the third frame P3.

[0117] For example, the shape of the decorative groove C1 is adapted to the shape of the decorative element 020.

[0118] Please refer to Figure 4 In the first direction, the decorative groove C1 is divided into a first groove D1 and a second groove D2. The first groove D1 is located on the side close to the outer surface of the middle frame 010, and the second groove D2 is located on the side away from the outer surface of the middle frame 010.

[0119] Among them, the maximum radial dimension of the first section D1 is greater than the maximum radial dimension of the second section D2, and the radial dimension refers to the direction perpendicular to the first direction.

[0120] For example, from the side away from the second segment D2 towards the side closer to the second segment D2, the radial dimension of at least some segments in the first segment D1 continuously decreases. The second segment D2 is a cylindrical segment.

[0121] By using the second groove D2 located near the interior of the middle frame 010, internal space of the middle frame 010 can be saved, interference with components inside the middle frame 010 can be avoided, and the utilization rate of internal space of the middle frame 010 can be improved.

[0122] Figure 10 This is a structural schematic diagram of another frame component provided in another embodiment of this application. Please refer to it. Figure 10 In some possible implementations, the inner surface of the middle frame 010 has a wiring groove C4 extending in a second direction, and the wiring groove C4 is connected to the decorative groove C1 in a first direction.

[0123] The first and second directions intersect (e.g., are perpendicular). Cable tray C4 is used to install connecting cables.

[0124] The connecting cable can be, for example, a flexible flat cable or a coaxial cable, which can be used to electrically connect the antenna inside the middle frame 010 to the motherboard in the internal space of the middle frame 010.

[0125] Connecting wires can be installed through the wiring groove C4. The wiring groove C4 is connected to the decorative groove C1 in the first direction, and an inspection port can be formed at the connection point. This inspection port can be used to check the sealing performance of the decorative part 020 fixed at the decorative groove C1, thus ensuring the processing quality of the frame assembly 000.

[0126] Please refer to Figure 8 or Figure 9 In some possible implementations, the decorative element 020 includes: a decorative support 021 and a decorative body 022.

[0127] At least a portion of the decorative bracket 021 is fixed within the decorative groove C1. The side of the decorative bracket 021 away from the bottom of the groove has a mounting groove C5, and the side of the decorative bracket 021 facing the bottom of the groove is connected to the connector 030.

[0128] At least a portion of the decorative body 022 is fixed within the mounting groove C5.

[0129] For example, the decorative body 022 is a decorative structure made of materials such as diamonds, gemstones, gold, or platinum. The first connector 031, the second connector 032, and the decorative support 021 are an integral structure.

[0130] In summary, by creating decorative grooves on the middle frame, with the groove openings and bottoms distributed along a first direction, and the groove openings located on the outer surface of the groove, and by connecting the connector on one side of the decorative element facing the bottom of the groove in the first direction, and the other side connecting to the bottom of the groove, when installing the decorative element within the groove, at least a portion of the decorative element and the connector can be placed within the groove through the grooves distributed on the outer surface of the groove in the first direction, and the connection between the decorative groove and the decorative element can be achieved through the connector. This effectively simplifies the fixing structure and process of the decorative element and frees up the internal space of the middle frame in the first direction. When the internal space of the middle frame in the first direction is freed up or increased, the utilization rate of the internal space of the middle frame or the stacking efficiency can be improved.

[0131] Figure 11 This is a schematic diagram of the structure of a terminal device according to one embodiment of this application. Please refer to it. Figure 11 In another embodiment of this application, a terminal device 100 is provided, including: a frame assembly 000, a battery cover 110, and a display screen 120. The frame assembly 000 is any of the frame assemblies described above.

[0132] The battery cover 110 and the display screen 120 are respectively connected to the two sides of the middle frame 010.

[0133] Terminal devices 100 include, for example, electronic products such as laptops, tablets, mobile phones, and e-readers.

[0134] In some possible implementations, the terminal device 100 also includes a battery installed within the space enclosed by the housing assembly 000, the battery cover 110, and the display screen 120.

[0135] Since the terminal device 100 adopts the frame assembly 000 in the above embodiments, the space occupied by the frame assembly 000 in the first direction can be freed up, that is, the internal space of the frame assembly 000 in the first direction can be increased. After the internal space of the frame assembly 000 in the first direction is increased, the space can be optimized and the space utilization rate can be improved. For example, the size of the battery in the first direction can be increased to improve the battery life of the terminal device 100, and the stacking efficiency can also be improved, making the internal space layout of the terminal device 100 more rational.

[0136] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0137] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
