Description

Technical Field

[0001] This utility model relates to the field of electronic device protective cases, and in particular to an ultra-thin functional electronic device protective case. Background Technology

[0002] Recently, a plethora of multifunctional phone cases have emerged on the market, with those incorporating various electronic features (such as Bluetooth, LED lights, and displays) becoming a market trend. However, the main problem with existing functional phone cases is their thickness and weight. They are also prone to interference with the phone's wireless charging coil, antenna, and magnetic functions, affecting normal phone use. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides an ultra-thin functional electronic device protective case.

[0004] An ultra-thin functional electronic device protective case includes a housing and a shielding plate; the housing has a cavity for accommodating the electronic device; an expansion slot with a one-way opening is provided in the upper side wall of the housing, and a bottom wall is spaced between the expansion slot and the cavity; the expansion slot is used to accommodate a PCB board; at least one vent is provided on the housing adjacent to the expansion slot; the shielding plate matches the size of the housing and closes the openings of the expansion slot and the vent.

[0005] Preferably, the length of the expansion slot matches the length of the upper sidewall of the housing.

[0006] Preferably, the opening direction of the expansion slot is opposite to the opening direction of the cavity.

[0007] Preferably, the opening of the vent hole faces the same direction as the opening of the expansion slot.

[0008] Preferably, there are two vent holes, which are located below the two ends of the expansion slot, respectively.

[0009] Preferably, the upper sidewall and the bottom wall are provided with corresponding pickup holes.

[0010] Preferably, a PCB board is placed in the expansion slot, and the PCB board has through holes corresponding to the position of the pickup hole.

[0011] Preferably, a charging hole is provided on the shielding plate at the position corresponding to the expansion slot.

[0012] Preferably, the housing is provided with a camera hole, which is located below the expansion slot.

[0013] Preferably, the PCB board integrates LED lights and a rechargeable battery.

[0014] This utility model provides an ultra-thin functional electronic device protective case. The expansion slot for housing the PCB board and its electronic components is located at the top of the case, away from the wireless charging coil on the phone, thus avoiding interference. Simultaneously, since the expansion slot houses the PCB board and other electronic components, the vent holes prevent the case from thickening after adhesive bonding, achieving the effect of venting and reducing adhesive usage to ensure the overall thickness of the case remains constant. Furthermore, the microphone holes on the top and bottom walls improve the phone's sound reception and antenna signal.

[0015] Compared with the prior art, the technical solution provided by this utility model makes the overall thickness thinner and lighter when the shell is equipped with the same PCB board and related electronic components, and the antenna signal and sound reception effect are better. It not only increases the playability of electronic functions, but also does not affect the normal functions of the mobile phone such as wireless charging and magnetic attraction, and has a thin and beautiful appearance.

[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Provides an ultra-thin functional electronic device protective case, such as Figures 1 to 6 As shown, it includes a housing 1 and a shielding plate 2; the housing has a cavity 3 for accommodating electronic equipment; an expansion slot 4 with a one-way opening is provided in the upper side wall 11 of the housing, and a bottom wall 12 is provided between the expansion slot and the cavity; the expansion slot is used to accommodate a PCB board 7; at least one vent 5 is provided on the housing adjacent to the expansion slot; the shielding plate matches the size of the housing and closes the openings of the expansion slot and the vent 5.

[0026] The electronic devices can be mobile phones, tablets, etc. The shape of the expansion slot can be flexibly configured. Located within the upper side wall of the housing, it is separated from the cavity by the bottom wall, keeping it away from power devices of common electronic devices (such as wireless charging coils) to avoid interference. Electronic components, including but not limited to rechargeable batteries, LEDs, and Bluetooth devices, are integrated on the PCB board. The number and shape of the vents can be flexibly configured, prioritizing their proximity to the expansion slot. A shielding plate is used to close the openings of the expansion slot and vents, enhancing the aesthetics of the housing exterior.

[0027] Furthermore, the length of the expansion slot is matched with the length of the upper sidewall of the housing, that is, the space range of the expansion slot is maximized so that more electronic components can be accommodated on the PCB board, corresponding to the possibility of adding more functions.

[0028] Furthermore, the opening direction of the expansion slot is opposite to the opening direction of the cavity, which facilitates the installation of the PCB board and related components into the expansion slot from the back of the housing.

[0029] Furthermore, the opening direction of the vent hole is the same as the opening direction of the expansion groove. That is, when the glue at the edge of the expansion groove is too thick, it is easier for the glue to seep into the adjacent vent hole, thereby achieving the purpose of reducing glue content. Preferably, there are two vent holes, which are located below both ends of the expansion groove, respectively, to facilitate glue reduction for the laterally arranged expansion groove.

[0030] Furthermore, corresponding microphone holes 6 are provided on the upper side wall of the housing and the bottom wall of the expansion slot. These microphone holes make the expansion slot a partially enclosed cavity. When the microphone holes correspond to the microphone and antenna positions of an electronic device (such as a mobile phone), the sound reception and antenna signal of the electronic device can be improved. Even further, through holes 71 corresponding to the positions of the microphone holes are provided on the PCB board, which can further enhance the aforementioned sound reception and antenna signal.

[0031] Furthermore, a charging hole 8 is reserved on the shielding plate at the position corresponding to the expansion slot. The charging hole corresponds to the charging interface supported on the PCB board, such as a Type-C interface hole, a DC hole, etc.

[0032] Furthermore, a camera hole 13 is provided on the housing, which is located below the expansion slot and corresponds to the camera area on the electronic device.

[0033] In one implementation, an LED 72 and a rechargeable battery are integrated on the PCB board; the LED is used to generate various lighting effects, and the rechargeable battery is used to power the devices on the PCB board. Understandably, based on the structure of this electronic device protective case, various other devices can be integrated on the PCB board to give the ordinary protective case multiple functions, while maintaining a relatively thin overall thickness.

[0034] The above is a description of the present utility model, which is used to help understand the present utility model. However, the implementation of the present utility model is not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the principle of the present utility model shall be considered as equivalent substitutions and shall be included within the protection scope of the present utility model.
