Technical Field

[0001] This utility model relates to the technical field, and in particular to an ultra-thin 2G feature phone. Background Technology

[0002] In the current telecommunications equipment market, 2G feature phones still maintain a certain market share due to their ease of use, low price, and stable signal, especially favored by the elderly and users with specific needs for basic communication functions. However, the 2G feature phones commonly found on the market have significant shortcomings in their structural design. These phones generally use a layout where the motherboard and battery are directly stacked together, and most structural components are board-type components. This traditional design makes the overall structure relatively thick and heavy. In the current trend of pursuing thin and portable electronic products, end users face many inconveniences when using and carrying these thick 2G feature phones, such as difficulty in putting them in pockets and poor hand feel, seriously affecting the user experience. Utility Model Content

[0003] The main purpose of this utility model is to provide an ultra-thin 2G feature phone, which aims to solve the problems of existing 2G feature phones being bulky, difficult to carry and use.

[0004] To achieve the above objectives, this utility model proposes an ultra-thin 2G feature phone, comprising:

[0005] A housing, which is divided into a first receiving cavity and a second receiving cavity along its length;

[0006] The motherboard and the display screen are installed in the first receiving cavity of the housing, with the motherboard stacked on the back of the display screen;

[0007] The battery and keypad are installed in the second receiving cavity of the housing, with the battery stacked on the back of the keypad;

[0008] A low-profile battery connector is used to establish an electrical connection between the motherboard and the battery.

[0009] The FPC connector is used to establish an electrical connection between the motherboard and the button board.

[0011] Optionally, it also includes a SIM card holder, which is disposed above the recessed battery connector.

[0012] Optionally, it also includes an earphone holder and a USB charging port disposed on the button panel.

[0013] Optionally, both the headphone jack and the USB charging port are recessed structures, and the total thickness of the headphone jack, the USB charging port, and the button panel after installation does not exceed the thickness of the battery.

[0014] Optionally, it also includes a battery cover, which is embedded in the housing so that the thickness of the battery cover after it is installed is at the same level as the thickness of the housing.

[0015] Optionally, the thickness of the motherboard and the keypad is 0.8±0.08mm.

[0016] Optionally, the thickness of the battery is 4±0.1mm.

[0017] Optionally, the thickness of the display screen is 2.2±0.1mm.

[0018] The beneficial effects of this utility model are as follows: it solves the problems of existing 2G feature phones being bulky, difficult to carry, and inconvenient to use. This application avoids directly stacking the motherboard and battery in the vertical direction by mounting the motherboard and display screen in the first part of the housing, and the battery and keypad in the second part, thus reducing the overall thickness and improving the device's lightness and portability. Simultaneously, it uses a recessed battery connector and an FPC connector to achieve signal transmission between the motherboard and keypad, reducing the vertical space occupied by this structure.

[0030] One embodiment of this utility model proposes an ultra-thin 2G feature phone, see reference. Figures 1 to 4 ,include:

[0031] The housing 1 is divided into a first receiving cavity 101 and a second receiving cavity 102 along its length.

[0032] The motherboard 4 and the display screen 3 are installed in the first receiving cavity 101 of the housing 1, and the motherboard 4 is stacked on the back of the display screen 3;

[0033] The battery 5 and the button panel 6 are installed in the second receiving cavity 102 of the housing 1, and the battery 5 is stacked on the back of the button panel 6;

[0034] A low-profile battery connector 8 is used to achieve an electrical connection between the motherboard 4 and the battery 5;

[0035] FPC connector 11 is used to realize the electrical connection between the motherboard 4 and the button board 6.

[0036] This application solves the problem of existing 2G feature phones being bulky, difficult to carry, and inconvenient to use. This application avoids directly stacking the motherboard 4 and display screen 3 in the vertical direction by mounting the motherboard 4 and display screen 3 in the first part of the housing 1, and the battery 5 and keypad 6 in the second part of the housing 1, thus reducing the overall thickness and improving the device's thinness and portability. Simultaneously, a recessed battery connector is used, and signal transmission between the motherboard 4 and keypad 6 is achieved through an FPC connector, reducing the vertical space occupied by this structure. In this embodiment, the housing 1 is made of a lightweight yet strong material. The first receiving cavity 101 is located inside the housing 1 near the top, and the second receiving cavity 102 is located inside the housing 1 near the bottom. The motherboard 4 and display screen 3 are fixed in the first receiving cavity 101 by stacking, and the battery 5 and keypad 6 are fixed in the second receiving cavity 102 by stacking. Furthermore, the motherboard 4 and battery 5 are arranged in a staggered manner, meaning they do not overlap in the thickness direction of the feature phone, thereby reducing the vertical stacking thickness and further reducing the overall thickness, improving the device's thinness and portability. The low-profile battery connector 8 is fixed to the motherboard 4, with one end electrically connected to the battery 5, thereby realizing the electrical connection between the motherboard 4 and the battery 5. Since the keypad 6 and the motherboard 4 are partitioned within the feature phone, the FPC connector 11 is configured as a flexible structure with a certain length. One end of the FPC connector 11 is connected to the motherboard 4, and the other end is connected to the keypad 6, which can adapt to the positional distribution of the two in different accommodating cavities of the housing 1, realizing flexible signal transmission connection.

[0037] Furthermore, the low-profile battery connector 8 is a recessed battery connector, which is mounted on the motherboard 4. In this embodiment, a slot 61 is formed at the bottom of the motherboard 4. The size of the slot 61 is adapted to the shape of the recessed battery connector, and the recessed battery connector is embedded in the slot 61, so that the height of the recessed battery connector is no higher than the SIM card slot 7. By embedding it in the slot 61, the recessed battery connector and the motherboard 4 form a tightly fitting structure, avoiding the increased thickness caused by the traditional on-board connector protruding from the surface of the motherboard 4.

[0038] Furthermore, it also includes a SIM card holder 7, which is disposed above the recessed battery connector. In this embodiment, the SIM card holder 7 and the recessed battery connector are arranged in a stacked configuration. Since the recessed battery connector is a recessed structure and is embedded in the slot 61 of the motherboard 4, its height is no higher than the position of the SIM card holder 7. Therefore, the SIM card holder 7 can be placed above the recessed battery connector, so that the SIM card holder 7 does not occupy additional space on the motherboard 4, and the total space occupied by the two in the vertical direction does not increase the thickness of the motherboard 4. This arrangement ensures the normal installation and use of the SIM card holder 7, enabling smooth insertion and reading of SIM cards. It also works in conjunction with the design of the recessed battery connector, avoiding the problem of increased overall thickness due to improper layout of the two. At the same time, the compact layout also makes the arrangement of components on the motherboard 4 more reasonable, saving the overall space of the motherboard 4 and helping to improve the compactness of the internal structure of the device.

[0039] Furthermore, it also includes a headphone jack 9 and a USB charging port 10 disposed on the button panel 6. Specifically, the headphone jack 9 and USB charging port 10 are located below the button panel 6, increasing the space available for the motherboard 4. Compared to the traditional approach of concentrating interfaces on the motherboard 4, this layout eliminates the need for the motherboard 4 to reserve space for the headphone jack 9 and USB charging port 10, thereby improving the space utilization of the motherboard 4. At the same time, integrating the headphone jack 9 and USB charging port 10 onto the button panel 6 simplifies the circuit design of the motherboard 4, reduces interference caused by cross-line crossings, and is beneficial to the stability of signal transmission.

[0040] Furthermore, both the headphone jack 9 and the USB charging port 10 are recessed structures, and the total thickness of the headphone jack 9, the USB charging port 10, and the button plate 6 after installation does not exceed the thickness of the battery 5. In this embodiment, the bottom of the button plate 6 has two slots 61. The headphone jack 9 and the USB charging port 10 adopt a recessed structure, and the headphone jack 9 and the USB charging port 10 are respectively embedded in the slots 61, so that the total thickness of the headphone jack 9, the USB charging port 10, and the button plate 6 after installation does not exceed the thickness of the battery 5. This achieves the interface function while avoiding increasing the overall thickness of the device due to the interface protruding. Since the battery 5 is stacked on the back of the button plate 6, when the total thickness of the headphone jack 9, the USB charging port 10, and the button plate 6 does not exceed the thickness of the battery 5, the headphone jack 9 and the USB charging port 10 will not protrude from the surface of the battery 5, allowing the battery 5 to fit tightly against the button plate 6, without the need to reserve additional protruding space for the headphone jack 9 and the USB charging port 10 on the housing 1.

[0041] Furthermore, it also includes a battery cover 2, which is embedded in the housing 1 so that the thickness of the battery cover 2 after it is installed is at the same level as the thickness of the housing 1. The battery cover 2 is embedded in the housing 1, and the housing 1 has a recessed structure or a snap-fit ​​structure at a corresponding position to accommodate the battery cover 2. When the battery cover 2 is installed in place, its outer surface is flush with the outer surface of the housing 1, forming a smooth and complete back profile. Unlike the protruding battery cover 2 in traditional feature phones, this embedded battery cover 2 avoids the extra thickness brought by the battery cover 2 itself, reduces the overall thickness of the device, and helps to achieve a slim and lightweight appearance. In this embodiment, the battery cover 2 is snapped into the housing 1. The inner circumference of the battery cover 2 is provided with several mounting blocks 21, and the outer circumference of the housing 1 is provided with several mounting grooves 103 corresponding to the mounting blocks 21. The mounting blocks 21 are provided with limiting grooves, and the mounting grooves 103 are provided with limiting protrusions. When installing the battery cover 2, insert the mounting block 21 into the mounting groove 103, then push the battery cover 2 upwards. The mounting block 21 will slide along the mounting groove 103. When the mounting block 21 slides to the position of the limiting protrusion, continue to push the battery cover 2 upwards. The limiting groove in the mounting block 21 will engage with the limiting protrusion in the mounting groove 103, thus fixing the battery cover 2 to the solid. When disassembly is required, simply push the battery cover 2 downwards. The limiting protrusion will be squeezed out of the limiting groove, and the mounting block 21 will slide downwards, at which point the battery cover 2 can be easily removed. This snap-fit ​​structure not only ensures the firmness of the battery cover 2 after installation and simplifies the installation and removal operation, but also hides the overall structure in the connection part, without increasing the overall thickness of the device.

[0042] Furthermore, the thickness of the motherboard 4 and the button board 6 is 0.8±0.08mm. A thickness of approximately 8mm ensures sufficient structural strength for both to support the soldering and installation of various electronic components, while also guaranteeing the structural strength of the button board 6 under frequent operation, preventing deformation or damage due to excessive thinness. When the motherboard 4 and the display screen 3 are stacked in the first receiving cavity 101, the relatively thin motherboard 4 does not significantly increase the overall stacking height in that area; similarly, when the button board 6 and the battery 5 are stacked in the second receiving cavity 102, their thickness does not excessively raise the position of the battery 5, thus avoiding wasted space in the vertical direction.

[0043] Furthermore, the thickness of the battery 5 is 4 ± 0.1 mm. The approximately 4 mm thickness of the battery 5 complements the 0.8 ± 0.08 mm thickness of the button plate 6, ensuring that the total thickness of the battery 5 in the vertical direction is not excessive after it is stacked on the back of the button plate 6, thus preventing an excessive increase in the overall thickness of the second receiving cavity 102. Simultaneously, the ± 0.1 mm tolerance provides a reasonable margin of error in the manufacturing of the battery 5, ensuring precise assembly of the battery 5 with the second receiving cavity 102 of the housing 1 and components such as the button plate 6.

[0044] Furthermore, the thickness of the display screen 3 is 2.2 ± 0.1 mm. This thickness of approximately 2.2 mm complements the thickness of the motherboard 4 (0.8 ± 0.08 mm). When the motherboard 4 is stacked on the back of the display screen 3, the total thickness of both in the vertical direction is reasonably compressed, without excessively increasing the overall thickness of the first receiving cavity 101. Simultaneously, the ± 0.1 mm tolerance provides appropriate error margin for the manufacturing of the display screen 3, ensuring precise assembly with the first receiving cavity 101 of the housing 1 and components such as the motherboard 4, avoiding any impact on the overall structural compactness due to dimensional deviations.

[0045] Furthermore, through the arrangement of the aforementioned components such as the motherboard 4, button board 6, display screen 3, and battery 5, the total thickness of the feature phone is 7.3mm, thereby achieving the thinness and lightness of the entire device.

[0046] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
