Description

Technical Field

[0001] This utility model relates to the field of mobile terminal accessories technology, specifically to a mobile phone protective case that combines active heat dissipation and auxiliary mobile phone shooting functions. Background Technology

[0002] As smartphone performance improves, the issue of overheating in high-load scenarios (such as mobile games and 4K video recording) is becoming increasingly prominent. Traditional phone cases mostly rely on passive heat dissipation (such as heat sinks and hollow designs), which has low heat dissipation efficiency and can easily lead to phone throttling and lag. Some active heat dissipation phone cases only focus on heat dissipation and do not integrate other practical functions, resulting in limited cost-effectiveness.

[0003] On the other hand, some phones lack a physical sliding focus module, requiring users to adjust focus via touchscreen. This can easily lead to image shifts due to hand tremors, especially in distant or macro photography, resulting in insufficient focusing accuracy and convenience. Furthermore, existing magnetic phone cases often conflict with heat dissipation / control modules due to magnet placement issues, leading to inaccurate magnetic positioning and blocked airflow, thus failing to balance MagSafe wireless charging with functional practicality.

[0004] To address the triple pain points of the existing technology mentioned above, namely "low heat dissipation efficiency, lack of shooting assistance, and poor functional compatibility", there is an urgent need for an integrated phone case that combines active heat dissipation, Bluetooth-assisted shooting, and MagSafe compatible magnetic attachment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing mobile phone cases, such as limited functionality, poor heat dissipation, lack of auxiliary shooting capabilities, and conflicts between magnetic attraction and functional modules. It provides a mobile phone case with a compact structure, high functional integration, active heat dissipation, and auxiliary mobile phone shooting, achieving a triple synergy of "precise heat dissipation + convenient shooting + compatible magnetic attraction".

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A mobile phone case for active heat dissipation and assisting mobile phone photography includes a housing, a motherboard, a battery, a fan, and control keys. The housing has an air inlet and an air outlet, which are connected to form a heat dissipation channel. The motherboard is disposed inside the housing and is electrically connected to the battery, fan, and control keys. The battery powers the motherboard and fan. The control keys connect to the mobile phone via a Bluetooth communication module and are used to send shooting control commands to the mobile phone.

[0008] Furthermore, it also includes a temperature sensor electrically connected to the motherboard; the motherboard is configured to control the start, stop, and speed adjustment of the fan based on the temperature value detected by the temperature sensor.

[0009] Furthermore, the shooting control command includes at least one of a focus adjustment command and a shutter trigger command.

[0010] Furthermore, it also includes a magnet, integrated within the housing, for providing magnetic connection functionality.

[0011] Furthermore, the magnet assembly is a ring-shaped magnet array, and its arrangement is compatible with the MagSafe standard, enabling the phone case to support magnetic alignment wireless charging.

[0012] Furthermore, the motherboard is provided with charging contacts, and the housing is provided with through holes corresponding to the positions of the charging contacts for wired charging of the battery through an external power source. Magnets are provided at the charging contacts to facilitate magnetic fixation with the charging head.

[0013] Furthermore, the fan is positioned so that when the phone is installed inside the phone case, it is directly opposite the core heat-generating area of ​​the phone's motherboard.

[0014] Furthermore, it also includes a cover plate, which is connected to the housing to form an accommodating cavity for encapsulating the motherboard, battery, and fan within the housing. The motherboard is suspended, with an air duct passing beneath it and surrounding the magnet to dissipate heat from the motherboard and the phone.

[0015] Optionally, the cover plate can be made of insulating nano-carbon copper foil to improve thermal conductivity. Part of the air duct passes under the motherboard, and part of it is in direct contact with the cover plate. In this way, the nano-carbon copper foil can quickly conduct the heat from the back of the phone into the air duct.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] High heat dissipation efficiency: Active and precise heat dissipation is achieved through "temperature sensor + adjustable speed fan + linear air duct". The fan is directly facing the mobile phone processor area, and the heat dissipation efficiency is improved by more than 60% compared with passive heat dissipation, which can effectively avoid frequency reduction and lag in high load scenarios.

[0018] Strong shooting assistance: The Bluetooth physical button solves the pain point of some mobile phones lacking a sliding focus module. The focus accuracy and ease of operation are superior to touch screen control, making it especially suitable for handheld stable shooting.

[0019] Good functional compatibility: The magnetic components avoid the heat dissipation airflow and electronic components, which is compatible with MagSafe magnetic wireless charging and has no risk of magnetic field interference; the built-in battery provides independent power and does not consume the phone's power, and the sealed cover design extends the life of internal components.

[0020] Highly practical: The compact structure combines four major functions: protection, heat dissipation, shooting, and magnetic attachment. It is compatible with mainstream Apple models and is suitable for everyday use, mobile games, outdoor shooting, and more. Attached Figure Description

[0029] The accompanying drawings have illustrated specific embodiments of the present invention, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1 to 7 This embodiment focuses on Apple iPhone 13, 14, and 15 series models. These models lack a physical sliding focus module in their hardware design, making touchscreen focusing prone to image shake. Furthermore, the processor generates significant heat under high load, which traditional passive cooling cases cannot adequately address. Therefore, this embodiment focuses on "precise active cooling + Bluetooth-assisted shooting + MagSafe compatible magnetic attachment + independent power supply," achieving multi-functional synergy in structural design and circuit layout. Of course, besides Apple iPhones, it can also be applied to other brands of mobile phones.

[0033] From an overall structural perspective, the phone case adopts a layered layout of "cover plate 7 - functional layer - shell 1". The motherboard 3 in the functional layer is the central hub of the circuit system, integrating core circuit modules such as power management, temperature detection, Bluetooth communication, fan drive and button response. It forms an electrical connection with the built-in battery 4, fan 2, temperature sensor and control keys 5, and together they support the operation of various functions.

[0034] like Figure 7 As shown, the selection of core components and circuit design of motherboard 3 revolve around four major aspects: power supply, detection, control, and communication. The power management circuit is the foundation of the entire system's energy supply and is divided into two parts: a charging circuit and a power supply circuit. The charging circuit consists of an external 5V power supply, charging contacts 31, a TP4056 charging management chip, and battery 4. The power supply circuit consists of battery 4, a low-dropout regulator, and various power-consuming modules. The 3.7V voltage output from battery 4 is regulated by an XC6206P332MR LDO to output a stable 3.3V voltage, which supplies the MCU, Bluetooth module, and temperature sensor; fan 2 is directly supplied with 3.7V voltage from battery 4.

[0035] The temperature detection circuit is the sensing end for the active cooling function, using an MF52-10K NTC thermistor as the sensing element. The MCU on motherboard 3 is an STM32F030C8T6, whose ADC module has a 12-bit resolution and a sampling rate set to 1Hz.

[0036] The fan drive circuit is the actuator for active cooling, and its core component is an AO3401 N-channel MOSFET. The MCU's GPIO pin outputs a PWM signal to the gate of the MOSFET. By adjusting the duty cycle of the PWM signal, the speed of fan 2 is adjusted. Of course, in some embodiments, a physical switch, such as a regular button or touch switch, can be added to turn the fan on, off, or in operation.

[0037] The Bluetooth communication circuit serves as the transmission bridge for the auxiliary shooting function. In this embodiment, the CC2541 low-power BLE module is selected. The module's TX and RX pins are connected to the MCU's UART pins, and the communication baud rate is set to 9600bps. The module's KEY pin is connected to the MCU's GPIO pin to control the module to enter pairing mode.

[0038] In terms of structural and circuit compatibility, magnet 6 uses neodymium iron boron permanent magnets, arranged in an alternating ring according to MagSafe standards, avoiding the motherboard 3 and battery 4 areas; cover plate 7 is made of a material with high thermal conductivity, fixed by buckles or ultrasonic welding, and has waterproof strips and waterproof membranes on the edges to achieve IP54 protection level.

[0039] Please see Figure 5 , 6 As shown, the distance and position between the air inlet 11 and the air outlet 12 can be adjusted according to actual needs. The motherboard 3 is suspended, with some air ducts passing under the motherboard 3 and surrounding the magnet 6 to carry away the heat from the motherboard 3. Some air ducts are directly in contact with the cover plate 7. In this way, the cover plate with nano-carbon copper foil can quickly conduct the heat from the back of the phone into the air ducts to carry away the heat from the motherboard and the phone.

[0040] Tests have shown that the circuit system in this embodiment can achieve a heat dissipation efficiency of more than 60% compared to traditional passive heat dissipation shells, more than double the full-frequency running time of the mobile phone processor, a focusing accuracy of ±0.1 times the focal length for shooting assistance functions, MagSafe magnetic charging efficiency of ≥90%, and the built-in battery 4 supports the fan 2 to work continuously at low speed for more than 8 hours, fully meeting the needs of users in daily use, mobile games, outdoor shooting and other scenarios.

[0041] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention. This application is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and embodiments are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the foregoing claims.

[0042] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
