Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to a bending structure for improving the top output force of the card tray beam. Background Technology

[0002] A mobile phone is a communication device that allows users to communicate with others. Mobile phones use a SIM (Subscriber Identity Module) card to identify the user. When communicating with others, the phone needs this SIM card. The SIM card needs to be purchased from the operator and installed in the phone's SIM card tray. The tray is then inserted into the phone, allowing the SIM card to connect to the phone's internal communication module. The phone can then use the SIM card to communicate with others.

[0003] This demonstrates the importance of the SIM card tray. As mobile phone functions become more diversified and intelligent, the internal space of mobile phones is constantly being compressed. To save space, the structure of the SIM card tray is also being continuously optimized and compressed, and the thickness of the SIM card tray is becoming smaller and smaller. For a specific example, please refer to the SIM card tray disclosed in Chinese Patent Publication No. CN118214440A. This type of SIM card tray has an extremely small thickness, with the thickness of its long side (i.e., side beam) and short side (i.e., cross beam) being only between 1mm and 1.5mm. As a result, when the SIM card tray is ejected, the long side and short side are prone to deformation. When the short side is deformed, the SIM card tray may become impossible to remove.

[0004] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

[0005] This utility model provides a bending structure to improve the top output force of the card holder crossbeam, aiming to solve the problem that the existing card holders, in pursuit of thinness and lightness, result in insufficient strength of the crossbeam and easy deformation.

[0006] To achieve the above objectives, this utility model provides a bending structure for improving the top output force of the card holder crossbeam, including a card holder body. The card holder body includes a pressing part, a crossbeam, and two side beams. The two side beams are spaced apart, and the two ends of the two side beams are respectively connected to the pressing part and the crossbeam.

[0007] The card holder body is composed of a metal substrate and an outer plastic layer covering at least a portion of the metal substrate; the metal substrate has a first reinforcing part formed by bending at the position corresponding to the crossbeam, and the thickness of the first reinforcing part is at least twice the thickness of the metal substrate other than the first reinforcing part.

[0008] In some embodiments, an upper structure bent upwards is formed on the metal substrate, a lower structure bent downwards is formed on the metal substrate, a middle structure is formed between the upper structure and the lower structure, and the upper structure, the middle structure and the lower structure are sequentially stacked to form the first reinforcing part.

[0009] In some embodiments, the metal substrate is provided with a second reinforcing part at the connection between the crossbeam and the side beam.

[0010] In some embodiments, the second reinforcing part is a recessed structure formed by stamping or a laminated structure formed by bending.

[0011] In some embodiments, the card holder body further includes a card placement section, which is surrounded by the pressing section, the crossbeam and two side beams, and a portion of the metal substrate or the outer plastic layer is located within the card placement section to form a support section.

[0012] In some embodiments, the pressing portion has an elastic abutment structure formed near the card placement portion.

[0013] In some embodiments, the metal substrate is provided with at least one bent connecting portion, which strengthens the connection between the metal substrate and the outer plastic layer.

[0014] In some embodiments, the metal substrate has at least one connection hole, and a portion of the outer plastic layer fills the connection hole.

[0015] In some embodiments, a sealing ring is formed on the outside of the pressing part.

[0016] In some embodiments, the upper and / or lower surfaces of the outer plastic layer are formed with card removal notches.

[0017] The technical effect of the bending structure for improving the top output force of the card tray beam involved in this utility model is as follows: through the design of the first reinforcing part in the metal matrix formed inside the card tray body, the thickness of the metal matrix in the part corresponding to the beam can be increased. In this way, the strength of the beam of the card tray body can be improved, the risk of beam deformation can be reduced, that is, the risk of the card tray not being able to be removed can be reduced, and at the same time, the thin and light characteristics of the card tray body can be preserved to the greatest extent.

Therefore, it should not be construed as a limitation of this utility model.

[0028] To more clearly illustrate the technical solution of this utility model, a preferred embodiment is provided below for reference. Figures 1-4A bending structure for improving the top output force of the card holder crossbeam includes a card holder body 1. The card holder body 1 includes a pressing part 1a, a crossbeam 1b, and two side beams 1c. The two side beams 1c are spaced apart, and the two ends of the two side beams 1c are respectively connected to the pressing part 1a and the crossbeam 1b.

[0029] The card holder body 1 is composed of a metal substrate 11 and an outer plastic layer 12 covering at least a portion of the metal substrate 11; the metal substrate 11 is provided with a first reinforcing part 111 formed by bending at the position corresponding to the crossbeam 1b, and the thickness of the first reinforcing part 111 is at least twice the thickness of the metal substrate 11 other than the first reinforcing part 111; the metal substrate 11 other than the first reinforcing part 111 mentioned here refers to other unbent parts of the metal substrate 11.

[0030] In this embodiment, the metal substrate 11 formed inside the card tray body 1 is designed with a first reinforcing part 111, which increases the thickness of the metal substrate 11 in the part corresponding to the crossbeam 1b. This can improve the strength of the crossbeam 1b of the card tray body 1, reduce the risk of crossbeam 1b deformation, and reduce the risk of the card tray not being able to be removed. At the same time, it can retain the thin and light characteristics of the card tray body 1 to the greatest extent.

[0031] In some embodiments, an upper structure 111a bent upwards is formed on the metal substrate 11, and a lower structure 111b bent downwards is formed on the metal substrate 11. A middle structure 111c is formed between the upper structure 111a and the lower structure 111b. The upper structure 111a, the middle structure 111c, and the lower structure 111b are sequentially stacked to form a first reinforcing part 111. With this design, the strength of the crossbeam 1b of the card tray body 1 involved in this embodiment can reach three times the strength of the crossbeam 1b of existing card trays. The crossbeam 1b of the card tray body 1 can withstand an ejection force of about 25N, and the crossbeam 1b will hardly deform when the card tray body 1 is ejected.

[0032] In some embodiments, the metal substrate 11 is provided with a second reinforcing portion 112 at the connection between the corresponding crossbeam 1b and side beam 1c; wherein the second reinforcing portion 112 is a stamped concave structure or a bent laminated structure. This design can improve the strength of the connection between the crossbeam 1b and the side beam 1c, and further reduce the risk of deformation of the crossbeam 1b.

[0033] In some embodiments, the card tray body 1 further includes a card placement portion 13, which is formed by a pressing portion 1a, a crossbeam 1b, and two side beams 1c. A portion of the metal substrate 11 or the outer plastic layer 12 is located within the card placement portion 13 to form a support portion 14. The card placement portion 13 is used to accommodate an SD card or a SIM card, while the support portion 14 is used to hold the SD card or SIM card so that the SD card or SIM card is stably placed within the card placement portion 13.

[0034] In some embodiments, a resilient abutment structure 15 is formed on the pressing part 1a near the card holder 13. The resilient abutment structure 15 is formed on the outer plastic layer 12 and is used to apply an elastic force to the SD card or SIM card placed in the card holder 13, thereby clamping the SD card or SIM card in the card holder 13; this resilient abutment structure 15 is particularly important for the card tray body 1 that can hold cards on both sides.

[0035] In some embodiments, a card placement mark 16 is formed on the surface of the outer plastic layer 12, which allows the user to know how to place the SD card and SIM card.

[0036] In some embodiments, the metal substrate 11 is provided with at least one bent connecting portion 113, which strengthens the connection between the metal substrate 11 and the outer plastic layer 12; in addition, the design of the bent connecting portion 113 can further improve the strength of the metal substrate 11.

[0037] In some embodiments, the metal substrate 11 is provided with at least one connection hole 114, and a portion of the outer plastic layer 12 is filled in the connection hole 114. By opening the connection hole 114, the connection strength between the metal substrate 11 and the outer plastic layer 12 can be further improved.

[0038] In some embodiments, a sealing ring 17 is formed on the outside of the pressing part 1a. When the card tray body 1 is installed in the mobile phone, the sealing ring 17 can seal the gap between the card tray body 1 and the mobile phone to prevent liquid from seeping into the inside of the mobile phone.

[0039] In some embodiments, a card removal notch 18 is formed on the upper and / or lower surfaces of the outer plastic layer 12. The card removal notch 18 allows the user to more easily remove the SD card or SIM card from the card holder 13.

[0040] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
