Description

Technical Field

[0001] This disclosure relates to the field of electronic device technology, and in particular to a mid-frame assembly and an electronic device. Background Technology

[0002] As users' demands for electronic devices gradually increase, the number of related accessories for these devices also increases. For example, to improve the aesthetics of electronic devices or to make them easier to carry, users use chains to attach them to the devices.

[0003] In related technologies, a chain is connected to a protective case of the electronic device, and then the protective case is fitted over the outside of the electronic device's frame. However, the protective case increases the overall thickness of the electronic device, reducing its aesthetic appeal.

[0004] Therefore, the key problem to be solved is how to add a hanging chain to the electronic device without increasing the overall thickness of the electronic device. Summary of the Invention

[0005] This disclosure provides a mid-frame component and an electronic device that can solve the technical problems existing in the related art. The technical solutions of the mid-frame component and the electronic device are as follows.

[0006] In a first aspect, this disclosure provides a mid-frame assembly, the mid-frame assembly including a mid-frame and a connector;

[0007] The side wall of the middle frame has mounting holes, and the connector includes a buckle and a hook, with the buckle fixed to the hook;

[0008] The buckle is inserted into the interior of the middle frame through the mounting hole, and the hook is located on the outside of the middle frame for connecting with the hanging chain.

[0009] In one possible implementation, the sidewall of the latch has a first snap-fit ​​structure, and the middle frame has a second snap-fit ​​structure. The first snap-fit ​​structure snaps into the second snap-fit ​​structure, wherein one of the first snap-fit ​​structure and the second snap-fit ​​structure is a protrusion and the other is a groove.

[0010] In one possible implementation, the sidewall of the mounting hole has two grooves, the two ends of which communicate with the interior of the middle frame and the exterior of the middle frame, respectively.

[0011] The first snap-fit ​​structure consists of two snap-fit ​​protrusions on the side wall of the latch, and the two snap-fit ​​protrusions respectively pass through the two grooves from the outside of the middle frame into the inside of the middle frame;

[0012] The second snap-fit ​​structure consists of two snap-fit ​​grooves on the inner wall of the middle frame. After the snap-fit ​​protrusion enters the interior of the middle frame, the connector rotates at a certain angle so that the snap-fit ​​protrusion is limited to the snap-fit ​​groove.

[0013] In one possible implementation, the latch includes a column and a cap arranged axially, the diameter of the cap being larger than the diameter of the column, the snap-fit ​​protrusion being located on the side wall of the column, and the hook being fixed to the cap;

[0014] The mounting holes include a first through hole and a second through hole arranged along the axial direction. The second through hole is larger than the diameter of the first through hole. The first through hole communicates with the interior of the middle frame, and the second through hole communicates with the exterior of the middle frame. The two grooves are located on the side wall of the first through hole.

[0015] The snap-fit ​​protrusion passes through the first through hole via the two grooves and snaps into the inner wall of the middle frame. The diameter of the cap is larger than the diameter of the first through hole, and the cap is confined within the second through hole.

[0016] In one possible implementation, the diameter of the cap body is greater than the distance between the two opposing sidewalls of the two grooves.

[0017] In one possible implementation, the diameter of the cap is 3.2mm-3.5mm, the diameter of the post is 1.6mm-2mm, and the distance between the two opposite sidewalls of the two grooves is 2.8mm-3.2mm.

[0018] In one possible implementation, the mid-frame component further includes an elastic element;

[0019] The elastic element is looped around the column, with one end of the elastic element abutting against the cap body and the other end abutting against the bottom wall of the second through hole.

[0020] In one possible implementation, the elastic element is a rubber ring.

[0021] In one possible implementation, the sidewall of the second through hole has an overflow groove;

[0022] The overflow groove is annular and surrounds the rubber ring, with the inner diameter of the overflow groove being larger than the outer diameter of the rubber ring.

[0023] In one possible implementation, the sidewall of the rubber ring has multiple grooves;

[0024] The plurality of grooves are evenly distributed along the circumference of the rubber ring.

[0025] In one possible implementation, the rubber ring has multiple grooves evenly distributed circumferentially on both opposite sidewalls.

[0026] In one possible implementation, the thickness of the rubber ring 3a is 0.7mm-1mm.

[0027] In one possible implementation, the mid-frame assembly further includes a sealing member that is inserted into the interior of the mid-frame through the mounting hole and is detachably connected to the mid-frame;

[0028] The middle frame assembly has a first state and a second state. In the first state, the connector is connected to the middle frame, and in the second state, the sealing member is connected to the middle frame.

[0029] In one possible implementation, in the second state, the end face of the sealing member facing the outside of the middle frame is flush with the outer wall of the middle frame.

[0030] In a second aspect, this disclosure also provides an electronic device including a mid-frame assembly as described in any of the first aspects.

[0031] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0032] This disclosure provides a mid-frame assembly that allows users to directly attach a lanyard to the hook of a connector when connecting an electronic device, eliminating the need for a protective case on the mid-frame assembly. This maintains the thickness of the electronic device and improves its aesthetics. Furthermore, eliminating the need for a protective case also facilitates heat dissipation, preventing overheating from affecting the lifespan of the electronic device.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings.

[0056] The terminology used in the embodiments of this disclosure is for illustrative purposes only and is not intended to limit the disclosure.

The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0057] As users' demands for electronic devices gradually increase, the number of related accessories for these devices also increases. For example, to improve the aesthetics of electronic devices or to make them easier to carry, users use chains to attach them to the devices.

[0058] In related technologies, a chain is connected to a protective case of the electronic device, and then the protective case is fitted over the outside of the electronic device. However, the protective case increases the overall thickness of the electronic device, reducing its aesthetics. Furthermore, the protective case can also affect the heat dissipation of the electronic device, causing it to reach higher temperatures and thus affecting its lifespan.

[0059] In view of the above-mentioned technical problems, this disclosure provides a mid-frame component, such as... Figure 1 and Figure 2As shown, the middle frame assembly includes a middle frame 1 and a connector 2. The side wall of the middle frame 1 has mounting holes 10. The connector 2 includes a latch 21 and a hook 22, with the latch 21 fixed to the hook 22. The latch 21 is inserted into the interior of the middle frame 1 through the mounting holes 10, and the hook 22 is located on the exterior of the middle frame 1 and is used to connect with the hanging chain 100.

[0060] In this embodiment, the specific structure of the hook 22 is not limited. Figure 3 As shown, the hook 22 can be a protrusion fixed to the latch 21, with the axis of the protrusion parallel or coincident with the axis of the latch 21. The side wall of the protrusion has a hanging hole 220 for the chain 100 to pass through, thus allowing the chain 100 to be connected to the hook 22. Alternatively, the hanging hole 220 can be a threaded hole, so that when the chain 100 has a screw, the chain 100 and the hanging hole 220 are threaded together. Alternatively, the hook 22 can also be a hanging ring, or a flexible hanging cord, etc.

[0061] The technical solution provided in this disclosure allows users to easily add a hanging chain 100 to the outside of an electronic device by simply connecting the chain 100 to the hook 22 of the mid-frame assembly. This eliminates the need for a protective case with hooks, thus avoiding an increase in the overall thickness of the electronic device and improving its aesthetics. Furthermore, not using a protective case also facilitates heat dissipation, preventing overheating from affecting the lifespan of the electronic device.

[0062] In some examples, connector 2 is detachably connected to the middle frame 1. When it is not necessary to attach the hanging chain 100 to the middle frame assembly, connector 2 can be removed from the middle frame 1, thereby preventing hook 22 from affecting the user's grip.

[0063] In some examples, the sidewall of the latch 21 has a first snap-fit ​​structure, and the middle frame 1 has a second snap-fit ​​structure. The first snap-fit ​​structure snaps into the second snap-fit ​​structure, wherein one of the first snap-fit ​​structure and the second snap-fit ​​structure is a protrusion and the other is a groove.

[0064] For example, the sidewall of the latch 21 has a protrusion, and the inner arm of the mounting hole 10 has a groove, with the protrusion confined within the groove.

[0065] Alternatively, the inner arm of the mounting hole 10 may have a protrusion, and the side wall of the latch 21 may have a groove, with the protrusion confined within the groove.

[0066] The following is an exemplary description of how the latch 21 and the middle frame 1 are connected.

[0067] In some examples, such as Figures 3-6As shown, the sidewall of the mounting hole 10 has two grooves 101, the two ends of which communicate with the interior and exterior of the middle frame 1, respectively. The first snap-fit ​​structure is that the sidewall of the latch 21 has two snap-fit ​​protrusions 211, which pass through the two grooves 101 from the exterior of the middle frame 1 into the interior of the middle frame 1. The second snap-fit ​​structure consists of two snap-fit ​​grooves 11 on the inner wall 1a of the middle frame 1. After the snap-fit ​​protrusions 211 enter the interior of the middle frame 1, the connector 2 rotates at a certain angle, so that the snap-fit ​​protrusions 211 are confined within the snap-fit ​​grooves 11.

[0068] like Figure 7 As shown, when installing the connector 2 on the middle frame 1, first align the two snap-fit ​​protrusions 211 axially with the two grooves 101 respectively. Then, pass the snap-fit ​​protrusions 211 through the grooves 101, so that the latch 21 passes through the mounting hole 10 and extends into the interior of the middle frame 1. Then, rotate the connector 2 (rotation direction as shown). Figure 7 (As indicated by the dashed arrow), the snap-fit ​​protrusion 211 is aligned axially with the snap-fit ​​groove 11. Finally, the connector 2 is pulled outwards towards the middle frame 1, causing the snap-fit ​​protrusion 211 to be positioned within the snap-fit ​​groove 11. This ensures a high connection strength between the middle frame 1 and the connector 2, preventing the connector 2 from detaching from the middle frame 1. The two snap-fit ​​protrusions are evenly distributed circumferentially along the mounting hole 10, resulting in more even force distribution on the latch 21. This prevents the latch 21 from shifting within the mounting hole 10, improving the reliability of the connector 2.

[0069] When it is no longer necessary to connect the hanging chain 100 to the middle frame assembly, the connector 2 can be removed from the middle frame 1. The removal process is as follows: Figure 8 As shown. First, press down on connector 2 so that the two snap-fit ​​protrusions 211 disengage from the two grooves 101 respectively. Then rotate connector 2 (rotation direction as shown). Figure 8 (In the direction indicated by the dashed arrow), align the snap-fit ​​protrusion 211 and the groove 101 axially. Finally, pull the connector 2 outward toward the middle frame 1 to disengage the connector 2 from the middle frame 1.

[0070] Among them, the two snap-fit ​​protrusions 211 can be evenly distributed along the circumference of the latch 21.

[0071] For example, the line connecting the two snap-fit ​​slots 11 and the line connecting the two recesses 101 can form a 90° angle. After the latch 21 passes through the mounting hole 10 and extends into the interior of the middle frame 1, rotating the rotating connector 2 90° clockwise or counterclockwise will axially align the snap-fit ​​protrusion 211 with the snap-fit ​​slot 11.

[0072] In some examples, such as Figure 3As shown, the latch 21 includes a column 21a and a cap 21b arranged axially, the diameter of the cap 21b being larger than the diameter of the column 21a. A snap-fit ​​protrusion 211 is located on the side wall of the column 21a, and a hook 22 is fixed to the cap 21b. Correspondingly, as... Figure 4 As shown, the mounting hole 10 includes a first through hole 10a and a second through hole 10b arranged axially, with the diameter of the second through hole 10b being larger than the diameter of the first through hole 10a. The first through hole 10a communicates with the interior of the middle frame 1, and the second through hole 10b communicates with the exterior of the middle frame 1. Two grooves 101 are located on the sidewall of the first through hole 10a. The mounting hole 10 can be considered as a stepped hole.

[0073] The snap-fit ​​protrusion 211 passes through the first through hole 10a via two grooves 101 and snaps into the inner wall 1a of the middle frame 1. The diameter of the cap 21b is larger than the diameter of the first through hole 10a, and the cap 21b is confined within the second through hole 10b. The snap-fit ​​protrusion 211 and the cap 21b can axially limit the latch 21, preventing the latch 21 from moving within the mounting hole 10, thereby enhancing the stability of the connection between the latch 21 and the middle frame 1. Furthermore, the snap-fit ​​connection method is relatively simple, making it easy for users or workers to connect the connector 2 to the middle frame 1.

[0074] Alternatively, in some other examples, the latch 21 may not have a cap 21b, and the diameter of the hook 22 may be larger than the diameter of the mounting hole 10. In this way, the snap-fit ​​protrusion 211 and the hook 22 can axially limit the latch 21.

[0075] In some examples, the length of the snap-fit ​​protrusion 211 along the radial direction of the latch 21 is 0.5mm-0.7mm. If the length of the snap-fit ​​protrusion 211 is too small, the latch 21 will easily detach from the mounting hole 10. If the length of the snap-fit ​​protrusion 211 is too large, the length of the groove 101 along the radial direction of the latch 21 will be too large, resulting in a larger overall size of the mounting hole 10. Since the thickness of the middle frame 1 is relatively small, it is not convenient to provide a large mounting hole on the middle frame 1.

[0076] The present disclosure does not limit the number of snap-fit ​​protrusions 211, and the number of snap-fit ​​protrusions 211 may be one or more. It is understood that the number of snap-fit ​​grooves 11 and the number of recesses 101 are the same as the number of snap-fit ​​protrusions 211.

[0077] In some examples, such as Figure 9 As shown, the diameter D of the cap 21b is greater than the distance L between the two opposite sidewalls of the two grooves 101. In this way, when the connector 2 is fixed to the middle frame 1, the cap 21b can cover the grooves 101, preventing the grooves 101 from being exposed and affecting the sealing performance of the middle frame 1.

[0078] For example, the diameter D of the cap 21b is 3.2mm-3.5mm, the diameter of the column 21a is 1.6mm-2mm, and the distance L between the two opposite sidewalls of the two grooves 101 is 2.8mm-3.2mm.

[0079] The present disclosure does not specifically limit the implementation of the detachable connection between the connector 2 and the middle frame 1. In other examples, the latch 21 and the mounting hole 10 can also be connected by threads.

[0080] In some examples, such as Figure 9 and Figure 10 As shown, the middle frame assembly also includes an elastic element 3. The elastic element 3 is looped around the column 21a, with one end of the elastic element 3 abutting against the cap 21b and the other end abutting against the bottom wall of the second through hole 10b. The elastic element 3 is always in a compressed state.

[0081] When installing connector 2, first press connector 2, and the elastic element 3 will further compress, causing the snap-fit ​​protrusion 211 to pass through the snap-fit ​​groove 11. After rotating connector 2 and aligning the snap-fit ​​protrusion 211 with the snap-fit ​​groove 11, stop pressing connector 2. This allows the elastic element 3 to apply a spring force to the cap 21b, with the spring force directed towards the outside of the middle frame 1. This causes the cap 21b to exert a pulling force on the column 21b towards the outside of the middle frame 1. In this way, the snap-fit ​​protrusion 211 can abut against the bottom wall of the snap-fit ​​groove 11, preventing the snap-fit ​​protrusion 211 from falling out of the snap-fit ​​groove 11. This prevents connector 2 from rotating or axially loosening, thus ensuring the stability of the connection between connector 2 and the middle frame 1.

[0082] Before installing connector 2, the elastic element 3 can be inserted through the cap 21b or the snap-fit ​​protrusion 211 and placed on the outside of the column 21a. This prevents the elastic element 3 from obstructing the snap-fit ​​protrusion 211 when installing connector 2.

[0083] For example, such as Figure 10 As shown, the elastic element 3 is a rubber ring 3a, and the inner wall of the rubber ring 3a abuts against the side wall of the column 21a. On the one hand, the rubber ring 3a can apply elastic force to the cap 21b, thereby ensuring the stability of the connection between the connector 2 and the middle frame 1. On the other hand, the rubber ring 3a can further improve the sealing performance of the middle frame 1.

[0084] When installing or removing connector 2, connector 2 needs to be pressed down, and the rubber ring 3a is compressed, causing the snap-fit ​​protrusion 211 to extend into the interior of the middle frame 1 and disengage from the snap-fit ​​groove 11. When connector 2 is fixed to the middle frame 1, the rubber ring 3a rebounds, causing the cap 21b to move outwards from the middle frame 1, thereby pulling the column 21a to move, and thus causing the snap-fit ​​protrusion 211 to extend into the snap-fit ​​groove 11. Therefore, the rubber ring 3a needs to have a large compression capacity.

[0085] In some examples, such as Figure 9 As shown, the sidewall of the second through hole 10b has an overflow groove 102. The overflow groove 102 is annular and surrounds the rubber ring 3a. The inner diameter of the overflow groove 102 is larger than the outer diameter of the rubber ring 3a. When the rubber ring 3a is compressed, its axial length becomes shorter and its diameter becomes longer, and the shorter the axial length, the longer the diameter. When the connector 2 is pressed, a portion of the rubber ring 3a can extend into the overflow groove 102, which facilitates radial deformation of the rubber ring 3a, and further facilitates axial deformation of the rubber ring 3a, resulting in a larger compression amount for the rubber ring 3a.

[0086] In addition, in order to make the rubber ring 3a have a larger compression, such as Figure 11 As shown, the sidewall of the rubber ring 3a has multiple grooves 30, which are evenly distributed along the circumference of the rubber ring 3a. Thus, when the rubber ring 3a is compressed, the grooves 30 facilitate deformation of the rubber ring 3a, resulting in a larger compression amount, which in turn facilitates the installation and disassembly of the connector 2.

[0087] For example, such as Figure 11 As shown, the two opposite sidewalls of the rubber ring 3a each have a plurality of grooves 30 evenly distributed in the circumferential direction, which can further improve the compression of the rubber ring 3a.

[0088] For example, the rubber ring 3a has 4-6 grooves 30 on each of its two opposite sidewalls. This allows the rubber ring 3a to have a large amount of compression while preventing it from being too easily compressed, which could affect the stability of the connection between the connector 2 and the middle frame 1.

[0089] In some examples, the thickness of the rubber ring 3a is 0.7mm-1mm. If the thickness of the rubber ring 3a is too small, the compression of the rubber ring 3a will also be too small, which is not conducive to the installation and disassembly of the connector 2. Since the thickness of the side wall of the middle frame 1 is limited, the thickness of the rubber ring 3a cannot be too large either.

[0090] When the hanging chain 100 is not needed on the mid-frame assembly, the connector 2 can be removed from the mid-frame 1. However, this will expose the mounting hole 10, affecting the sealing of the mid-frame assembly and allowing external debris or water to easily enter the interior of the mid-frame assembly. If the connector 2 is not removed from the mid-frame 1, the hook 22 will affect the user's grip.

[0091] Therefore, in some examples, such as Figure 12As shown, the middle frame assembly also includes a sealing member 4, which is inserted into the middle frame 1 through the mounting hole 10 and detachably connected to the middle frame 1. The middle frame assembly has a first state and a second state. In the first state, the connector 2 is connected to the middle frame 1. In the second state, the sealing member 4 is connected to the middle frame 1. The middle frame assembly is in the first state when connected to the hanging chain 100. When the middle frame assembly and the hanging chain 100 are separated, it can be in the second state. In the second state, the sealing member 4 prevents the mounting hole 10 from being exposed and does not affect the user's grip.

[0092] For example, such as Figure 13 As shown, the structure of the sealing member 4 is roughly the same as that of the latch 21 of the connector 2. The side wall of the sealing member 4 has two lugs 41, which can extend into the interior of the middle frame 1 through the groove 101. After the sealing member 4 is rotated at a certain angle, the two lugs 41 are respectively confined in the two snap-fit ​​grooves 11.

[0093] When the sealing component 4 is connected to the middle frame 1, the rubber ring 3a surrounds the sealing component 4. Under the elastic force of the rubber ring 3a, the two lugs 41 of the sealing component 4 can abut against the bottom wall of the snap-fit ​​groove 11, preventing the lugs 41 from falling out of the snap-fit ​​groove 11. This ensures that the sealing component 4 cannot rotate or loosen axially, guaranteeing the stability of the connection between the sealing component 4 and the middle frame 1.

[0094] It is understandable that the specific assembly and disassembly steps of the sealing component 4 and the middle frame 1 are roughly the same as those of the connecting component 2 and the middle frame 1, and will not be repeated here.

[0095] For example, the end face of the sealing member 4 facing the outside of the middle frame 1 has a slot or cross slot, which allows a tool to be inserted into the slot or cross slot, making it easy to rotate the sealing member 4 and to press the sealing member 4 towards the inside of the middle frame 1.

[0096] In some examples, in the second state, the end face of the sealing element 4 facing the outside of the middle frame 1 is flush with the outer wall 1b of the middle frame 1, thereby avoiding affecting the user's feel.

[0097] In some examples, the middle frame assembly may include two connectors 2 and two sealing members 4. Correspondingly, the sidewall of the middle frame 1 may have two mounting holes 10, which may be located on opposite sides of the middle frame 1, or at opposite ends of the same sidewall. Depending on the user's needs for using the hanging chain 100, the user may connect one connector 2 and one sealing member 4 to the two mounting holes 10 respectively, or connect the two connectors 2 to the two mounting holes 10 respectively, or connect the two sealing members 4 to the two mounting holes 10 respectively.

[0098] This disclosure also provides an electronic device, which includes the aforementioned mid-frame component.

[0099] Among them, electronic devices can be mobile phones or tablets, etc.

[0100] The electronic device provided in this embodiment features a frame 1 connected to a connector 2. Therefore, when the electronic device needs to be connected to the chain 100, the chain 100 can be directly connected to the main body of the electronic device. This eliminates the need for a protective casing, resulting in a thinner overall device and improved aesthetics. Furthermore, eliminating the need for a protective casing also facilitates heat dissipation, preventing overheating from affecting the device's lifespan.

[0101] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the principles of this disclosure should be included within the protection scope of this disclosure.
