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 their 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. Utility Model Content

[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, a connector, and a limiting member;

[0007] The side wall of the middle frame has a through hole, and the connector includes a column and a hook along the axial direction. The column passes through the through hole and is threadedly connected to the middle frame. The hook is located outside the middle frame and is used to connect a hanging chain.

[0008] The side wall of the column has a first anti-loosening surface, which is planar. The limiting member is fixed inside the middle frame and abuts against the first anti-loosening surface. The limiting member is elastic.

[0009] In one possible implementation, the limiting member includes a main body and a bent portion;

[0010] The main body and the bent portion are arranged in a bent manner. The main body is fixed to the inner wall of the middle frame, and the end of the bent portion away from the main body abuts against the first anti-loosening surface.

[0011] In one possible implementation, the main body includes a first segment and a second segment, with the two ends of the second segment connected to the first segment and the bent portion, respectively.

[0012] The first segment is fixed to the side wall of the middle frame, the side wall of the middle frame has a groove, and the second segment and the bent portion are located between the groove and the first anti-loosening surface.

[0013] In one possible implementation, the limiting member includes a fixing piece, a first spring piece, and a second spring piece, wherein the fixing piece is fixed inside the middle frame, and the first spring piece and the second spring piece are arranged at intervals.

[0014] The column has two first anti-loosening surfaces, which are arranged opposite to each other, and the first spring and the second spring respectively abut against the two first anti-loosening surfaces.

[0015] In one possible implementation, the width direction of the first spring and the width direction of the second spring are perpendicular to the axis of the connector.

[0016] In one possible implementation, the middle frame includes a middle frame body and a nut;

[0017] The nut is fixed to the side wall of the middle frame body, and the nut is opposite to the through hole. The column is threadedly connected to the nut.

[0018] In one possible implementation, the first anti-loosening surface is located inside the nut;

[0019] The nut has an opening on its side wall, and the limiting member extends into the opening and abuts against the first anti-loosening surface.

[0020] In one possible implementation, the nut includes a nut body and a base, the nut body being fixed to the base, the base having a mounting hole opposite to the through hole;

[0021] The side wall of the middle frame body has a first baffle and a second baffle arranged opposite to each other. The first baffle has a first limiting groove and the second baffle has a second limiting groove. The first limiting groove and the second limiting groove are opposite to each other. The two ends of the base are respectively located in the first limiting groove and the second limiting groove.

[0022] In one possible implementation, the mid-frame assembly further includes a sealing member, which is threadedly connected to the mid-frame through the through hole, and the sealing member has a second anti-loosening surface, which is planar.

[0023] The middle frame assembly has a first state and a second state. In the first state, the connector is connected to the middle frame. In the second state, the sealing member is connected to the middle frame, and the sidewall of the limiting member abuts against the second anti-loosening surface.

[0024] In a second aspect, this disclosure provides an electronic device including a mid-frame assembly as described in any of the first aspects.

[0025] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0026] This disclosure provides a mid-frame assembly. When a user needs to attach a lanyard to an electronic device, the connector with a hook is tightened onto the mid-frame, and then the lanyard is connected to the hook. This eliminates the need for a phone case on the outside of the electronic device, resulting in a thinner device. Furthermore, because the connector's column has a flat first anti-loosening surface, and the limiting member abuts against this surface, the limiting member prevents the connector from rotating. This prevents the connector from loosening under no loosening force, making it less likely to detach from the mid-frame. When the user needs to loosen or tighten the connector, under a larger external force, the limiting member deforms under the pressure of the connector, allowing the connector to rotate.

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

[0052] 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.

[0054] This disclosure provides a mid-frame component, such as... Figure 1 and Figure 2 As shown, the middle frame assembly includes a middle frame 1, a connector 2, and a limiting member 3. Figures 3-5 As shown, the side wall of the middle frame 1 has a through hole 10. The connector 2 includes a column 21 and a hook 22 along the axial direction. The column 21 passes through the through hole 10 and is threadedly connected to the middle frame 1. The hook 22 is located outside the middle frame 1 and is connected to the hanging chain 100. The side wall of the column 21 has a first anti-loosening surface 211, which is planar. The limiting member 3 is fixed inside the middle frame 1, and the side wall of the limiting member 3 abuts against the first anti-loosening surface 211. The limiting member 3 is elastic.

[0055] The connector 2 may also include a cap 23, the diameter of which is larger than the diameter of the column 21, and the cap 23 is located between the column 21 and the hook 22. The side wall of the middle frame 1 also has a positioning hole 15, which is connected to the through hole 10, and the diameter of the positioning hole 15 is larger than the diameter of the through hole 10, with the cap 23 located in the positioning hole 15.

[0056] This embodiment does not limit the specific structure of the hook 22. The hook 22 includes a first limiting block 221, a fixing block 222, and a second limiting block 223 connected axially in sequence. The diameters of the first limiting block 221 and the second limiting block 223 are larger than the diameter of the fixing block 222. The first limiting block 221 is fixed to the cap body 23. The chain 100 is sleeved on the fixing block 222. The first limiting block 221 and the second limiting block 223 limit the chain to prevent it from falling off the hook 22. The end face of the second limiting block 223 may have a slot or a cross slot, allowing a tool to be inserted into the slot or cross slot for easy rotation of the connector 2. Alternatively, the hook 22 may also have a boss with a hanging hole, and the boss is fixed to the cap body 23.

[0057] The technical solution provided in this disclosure allows users to connect a hanging chain 100 to an electronic device simply by tightening the connector 2 with hooks 22 onto the middle frame 1, and then connecting the hanging chain 100 to the hooks 22. This eliminates the need for a phone case on the outside of the electronic device, resulting in a thinner device. Furthermore, because the column 21 of the connector 2 has a planar first anti-loosening surface 211, and the limiting member 3 abuts against the first anti-loosening surface 211, the limiting member 3 can prevent the connector 2 from rotating. This prevents the connector 2 from loosening under no loosening force, making it less likely for the connector 2 to detach from the middle frame 1. When the user needs to loosen or tighten the connector 2, under a larger external force, the limiting member 3 deforms under the pressure of the connector 2, allowing the connector 2 to rotate.

[0058] The following is an exemplary description of one implementation of the limiting member 3.

[0059] In some examples, such as Figure 4 and Figure 5 As shown, the limiting member 3 includes a main body 31 and a bent part 32. The main body 31 and the bent part 32 are arranged in a bent manner. The main body 31 is fixed to the inner wall of the middle frame 1, and the end of the bent part 32 away from the main body 31 abuts against the first anti-loosening surface 211.

[0060] When installing or removing connector 2, under the action of external force, connector 2 tends to rotate, thereby compressing the bent portion 32. This causes the bent portion 32 to deform, which in turn allows connector 2 to rotate.

[0061] In some examples, such as Figure 4As shown, the main body 31 includes a first segment 311 and a second segment 312, with both ends of the second segment 312 connected to the first segment 311 and the bent portion 32, respectively. The first segment 311 is fixed to the side wall of the middle frame 1, and the side wall of the middle frame 1 has a groove 1a. The second segment 312 and the bent portion 32 are located between the groove 1a and the first anti-loosening surface 211. When installing or removing the connector 2, the connector 2 presses against the bent portion 32, and the bent portion 32 transmits the pressure to the main body 31. The groove 1a on the side wall of the middle frame 1 allows the main body 31 to deform in a direction away from the connector 2, thereby facilitating the installation or removal of the connector 2.

[0062] After the connector 2 is tightened onto the middle frame 1, the main body 31 is opposite to the first anti-loosening surface 211.

[0063] In other examples, the sidewalls of the middle frame 1 may not have the groove 1a. The connector 2 can be installed or removed solely by external force and the deformation of the bending portion 32.

[0064] The following is an exemplary description of another implementation of the limiting member 3.

[0065] In some examples, such as Figures 6-9 As shown, the limiting member 3 includes a fixing piece 33, a first spring piece 34, and a second spring piece 35. The fixing piece 33 is fixed inside the middle frame 1, and the first spring piece 34 and the second spring piece 35 are arranged at intervals and located on the same side of the fixing piece 33. The column 21 has two first anti-loosening surfaces 211, and the two first anti-loosening surfaces 211 are arranged opposite to each other. The first spring piece 34 and the second spring piece 35 abut against the two first anti-loosening surfaces 211 respectively.

[0066] When installing or removing connector 2, under the action of external force, connector 2 tends to rotate, thereby compressing the first spring 34 and the second spring 35. This causes the first spring 34 and the second spring 35 to deform, thus allowing connector 2 to rotate. The first spring 34 and the second spring 35 provide a high connection strength between connector 2 and the middle frame 1, making connector 2 less prone to loosening.

[0067] In some examples, such as Figure 9 As shown, the width direction of the first spring piece 34 and the width direction of the second spring piece 35 are perpendicular to the axis A of the connector 2. This ensures that the first spring piece 34 and the second spring piece 35 can only deform under a relatively large external force, meaning that the connector 2 can only be loosened under a relatively large external force. This helps to improve the connection strength between the connector 2 and the middle frame 1, preventing the connector 2 from detaching from the middle frame 1.

[0068] In some examples, the sidewall of the through hole 10 in the middle frame 1 may have threads, and the connector 2 may be directly threaded to the sidewall of the through hole 10.

[0069] In other examples, such as Figure 10 As shown ( Figure 10 for Figure 4 (A partially enlarged view) shows that the middle frame 1 includes a middle frame body 11 and a nut 12. The nut 12 is fixed to the side wall of the middle frame body 11, and the nut 12 is opposite to the through hole 10. The column 21 is threadedly connected to the nut 12. In this way, the connection area between the column 21 and the middle frame 1 can be increased, thereby increasing the connection strength between the column 21 and the middle frame 1, making it less likely for the connector 2 to fall off the middle frame 1.

[0070] In some examples, the first anti-loosening surface 211 is located inside the nut 12. For example... Figures 10-12 As shown, the side wall of the nut 12 has an opening 120, and the limiting member 3 extends into the opening 120 and abuts against the first anti-loosening surface 211. In this way, the nut 12 can be threadedly connected to the column 21 without obstructing the abutment between the limiting member 3 and the first anti-loosening surface 211.

[0071] Alternatively, in some other examples, the sidewall of the nut 12 may not have an opening 120. The post 21 extends from the nut 12, allowing the retaining member 3 to abut against the first anti-loosening surface 211.

[0072] For example, such as Figure 10 As shown, when the limiting member 3 includes the main body 31 and the bent part 32, the bent part 32 extends into the opening 120.

[0073] For example, such as Figure 11 As shown, when the limiting member 3 includes a fixing piece 33, a first spring piece 34 and a second spring piece 35, the nut 12 has two openings 120, and the first spring piece 34 and the second spring piece 35 extend into the two openings 120 respectively.

[0074] In some examples, such as Figures 11-13 As shown, the nut 12 includes a nut body 121 and a base 122. The nut body 121 is fixed to the base 122, and the base 122 has a mounting hole 1221, which is opposite to the through hole 10. The side wall of the middle frame body 11 has a first baffle 13 and a second baffle 14 arranged opposite to each other. The first baffle 13 has a first limiting groove 131, and the second baffle 14 has a second limiting groove 141. The first limiting groove 131 and the second limiting groove 141 are opposite to each other, and the two ends of the base 122 are respectively located in the first limiting groove 131 and the second limiting groove 141.

[0075] The opening 120 is located at the connection between the nut body 121 and the base 122. Alternatively, the opening 120 is located in the nut body 121.

[0076] For example, the base 122 is rectangular and abuts against the bottom wall of the middle frame 1, thereby achieving circumferential limiting of the nut 12.

[0077] In some examples, such as Figure 14 As shown ( Figure 14 for Figure 6 (Partial enlarged view), the fixing piece 33 is fixed to the base 122. The first spring piece 34 and the second spring piece 35 are bent in the same direction relative to the fixing piece 33. The fixing piece 33 abuts against the first side wall of the base 122, and the first spring piece 34 and the second spring piece 35 abut against the second side wall of the base 122. The first side wall and the second side wall are two adjacent side walls.

[0078] When the hanging chain 100 is not needed on the mid-frame assembly, the connector 2 can be directly removed from the mid-frame 1. However, this will expose the through 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.

[0079] Therefore, in some examples, such as Figure 15 and Figure 16 As shown, the middle frame assembly also includes a sealing member 4. The sealing member 4 is threadedly connected to the middle frame 1 through a through hole 10. The sealing member 4 has a second anti-loosening surface 41, which is planar. The middle frame assembly has a first state and a second state. In the first state, the connecting member 2 is connected to the middle frame 1, allowing the hanging chain 100 to be connected to the middle frame assembly. In the second state, the sealing member 4 is connected to the middle frame 1, and the side wall of the limiting member 3 abuts against the second anti-loosening surface 41. The second anti-loosening surface 41 and the limiting member 3 can prevent the sealing member 4 from rotating, avoiding loosening of the sealing member 4 under no loosening force, making it difficult for the sealing member 4 to fall off the middle frame 1.

[0080] For example, the sealing member 4 includes a rod 42 and a head 43, the diameter of the head 43 being larger than the diameter of the rod 42, the rod 42 penetrating through the through hole 10, and the rod 42 being located in the positioning hole 15.

[0081] For example, the end face of the head 43 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.

[0082] 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 through holes 10, which may be located on opposite sidewalls 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 through holes 10 respectively, or connect the two connectors 2 to the two through holes 10 respectively, or connect the two sealing members 4 to the two through holes 10 respectively.

[0083] This disclosure also provides an electronic device, which includes the aforementioned mid-frame component.

[0084] Among them, electronic devices can be mobile phones or tablets, etc.

[0085] 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, the connector 2 and the frame 1 have a high connection strength, making it difficult for the chain 100 to detach from the electronic device.

[0086] 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.
