[0032] Reference Figure 1 and Figure 2 As shown, a mobile phone case with low-temperature charging and heating functions includes:
[0033] Casing 100;
[0034] The first receiving cavity 200 and the second receiving cavity 300 are both located inside the housing 100, and the first receiving cavity 200 and the second receiving cavity 300 are arranged adjacent to each other; the first receiving cavity 200 is used to place the mobile phone 600, and the second receiving cavity 300 is used to place the charging module 500.
[0035] A heating module 400 is located between the first receiving cavity 200 and the second receiving cavity 300; the heating module 400 is connected to the charging module 500;
[0036] The heating module 400 is provided with a temperature acquisition unit 410, which is used to acquire the temperature inside the first receiving cavity 200.
[0037] When the heating module 400 is in the off state and the temperature in the first accommodating cavity 200 is less than A, the heating module 400 switches to the on state;
[0038] When the heating module 400 is in the on state and the temperature in the first accommodating cavity 200 is less than B or greater than C, the heating module 400 switches to the off state.
[0039] By using the heating module 400 disposed between the first receiving cavity 200 and the second receiving cavity 300, both receiving cavities can be heated simultaneously, so that both the mobile phone 600 and the charging module 500 are at a normal internal temperature.
[0040] In this embodiment, the charging module 500 uses a low-temperature power bank and a low-temperature charging chip. In extremely cold conditions of -50°C, it can both charge the dedicated mobile phone 600 and provide power to the heating module 400.
[0041] In some embodiments of this utility model, reference continues to be made to... Figure 1 and Figure 2 As shown, the housing 100 includes a first surface 110, a second surface 120, and symmetrically arranged side surfaces 130; the first surface 110, the heating module 400, and the side surfaces 130 form a first receiving cavity 200; the second surface 120, the heating module 400, and the side surfaces 130 form a second receiving cavity 300.
[0042] Specifically, in order to adapt to the shape and structure of the mobile phone 600, the various accommodating cavities formed within the housing 100 are rectangular parallelepipeds.
[0043] The housing 100 includes six surfaces, including a first surface 110, a second surface 120, two side surfaces 130, a bottom surface, and a top surface. The first surface 110 and the second surface 120 are arranged parallel to each other and serve as the mating surfaces of the mobile phone 600 and the charging module 500, respectively; the two side surfaces 130 are used to connect the first surface 110 and the second surface 120.
[0044] In some other embodiments, the housing 100 is made of special camouflage fabric, because the special camouflage fabric can not only blend into the soldiers patrolling Yanbian for easy concealment, but also has the functions of windproof, coldproof and rainproof.
[0045] Specifically, the first surface 110, together with the heating module 400 and the side surface 130, forms a first receiving cavity 200; the first receiving cavity 200 is used to place the mobile phone 600, and in order to facilitate the operation of the mobile phone 600 on the first surface 110, a viewing window film is provided on the first surface 110; when the mobile phone 600 is located in the first receiving cavity 200, the viewing window film is attached to the display screen of the mobile phone 600.
[0046] The viewing window film is primarily made of a high-definition frosted film material, which serves to prevent glare and provide high touch sensitivity, allowing users to switch screen information and use the front-facing camera without removing the phone. It also prevents condensation caused by temperature differences between the inside and outside of the phone in low-temperature conditions.
[0047] The first receiving cavity 200 and the second receiving cavity 300 are isolated by a heating module 400.
[0048] The heating module 400 also includes a temperature control switch 420, a resistance coil 430, and a heat preservation unit 440; the resistance coil 430 is connected to the charging module 500 through the temperature control switch 420.
[0049] In some embodiments of this utility model, the temperature control switch 420, the resistance coil 430, and the temperature acquisition unit 410 are all disposed within the heat preservation unit 440.
[0050] In some embodiments of this utility model, the heat preservation unit 440 comprises a waterproof layer and a heat preservation layer, the waterproof layers are symmetrically arranged, and the heat preservation layer is located between the two waterproof layers; the heating module 400 is bendable.
[0051] Reference Figure 3As shown, the heating module 400 uses a PI thin film heater, which is composed of a plush lining, insulation cotton, a temperature control switch 420, a resistance coil 430, and a sensor. It can not only effectively keep the temperature, but also effectively alleviate the collision and friction problem between the mobile phone 600 and the charging module 500 during use, thus playing a role in heat preservation and protection.
[0052] In some embodiments of this utility model, the main performance indicators of the charging module 500 are as follows: it can input via Micro or Type-C, USB; 5V / 2A, USB2.0 output; capacity is 9600mAh / 36.48Wh; operating temperature is -50° to 35°.
[0053] In some embodiments of this utility model, the charging module 500 is provided with multiple charging interfaces, and the charging interfaces are connected to the mobile phone 600 or the heating module 400.
[0054] In this embodiment, the charging module 500 is provided with at least two charging ports. One port can be connected to the mobile phone 600 via a charging cable, and the charging needs of the mobile phone 600 can be met as long as the charging module 500 is within its operating temperature range. The other charging port can be connected to the heating module 400 to meet the automatic heating function of the heating module 400.
[0055] In some embodiments of this utility model, reference continues to be made to... Figure 1 and Figure 2 As shown, the top of the 600 sets of mobile phones is also provided with a sealing cover, which is foldable relative to the first surface 110.
[0056] Specifically, the sealing cover is a foldable flat plate structure, and the sealing cover extends upward along the first surface 110; the sealing cover may be made of the same material as the first surface 110.
[0057] During use, after placing the mobile phone 600 and the charging module 500 in the first receiving cavity 200 and the second receiving cavity 300 respectively, the sealing cover can be folded towards the second surface 120; the sealing cover 140 seals the top surface of the first receiving cavity 200 and the second receiving cavity 300.
[0058] In some embodiments of this utility model, the sealing cover 140 is provided with a fitting portion 150, and the second surface 120 is provided with a mating portion 160; when the sealing cover 140 is folded relative to the first surface 110, the fitting portion 150 and the mating portion 160 are attracted and fixed together.
[0059] In some embodiments of this utility model, the fitting part 150 and the mating part 160 are attracted and fixed by magnets; during use, after the sealing cover 140 is bent, the fitting part 150 gradually approaches the mating part 160 until the two are attracted together to complete the sealing of the first receiving cavity 200 and the second receiving cavity 300, which has a heat preservation effect, thereby reducing the rate of temperature drop of the first receiving cavity 200 and the second receiving cavity 300 in extremely cold environments.
[0060] In some embodiments of this utility model, a wire clip 170 is also provided on the outer side of the second surface 120; the wire clip 170 is used to fix the mobile phone 600 sets.
[0061] Specifically, the cable clip 170 can be made of stainless steel, which makes it lightweight, sturdy and rust-resistant. The cable clip 170 can be clipped to the belt or worn on the shoulder to fix the phone 600 case.
[0062] The working process of the phone case is as follows:
[0063] The charging module 500 is placed into the second receiving cavity 300 and connected to the USB interface; the temperature acquisition unit 410 acquires the temperature inside the mobile phone 600 shell; when the temperature inside the mobile phone 600 shell is less than 0°C, the temperature control switch 420 is in the open state, the charging module 500 supplies power to the resistance coil 430, and the resistance coil 430 heats the first receiving cavity 200 and the second receiving cavity 300;
[0064] The temperature acquisition unit 410 collects the temperature inside the phone 600 casing in real time. When the temperature inside the phone 600 casing exceeds 10°C, it indicates that the external ambient temperature has not reached a cold level, so the temperature control switch 420 is adjusted to the off state. When the temperature inside the phone 600 casing is below -50°C, it indicates that the external ambient temperature has reached an extremely cold level, exceeding the operating temperature range of the charging module 500, so the temperature control switch 420 is adjusted to the off state.
[0065] In other words, when the temperature control switch 420 is in the open state and the temperature inside the mobile phone 600 is between -50℃ and 10℃, the charging module 500 can continuously charge the heating module 400 and the mobile phone 600.
[0066] When the temperature control switch 420 is in the open state and the temperature inside the mobile phone 600 is not lower than 0°C, the charging module 500 can continuously charge the heating module 400 and the mobile phone 600.
[0067] The technical solution of this utility model has the following technical advantages over the prior art:
[0068] This invention, through its built-in heating module 400 and low-temperature charging module 500, enables the mobile phone 600 to charge freely in extremely cold environments, while ensuring the normal communication function of the mobile phone 600.
[0069] In addition, a viewing window film is set on the outside of the phone 600, which can be used to operate the phone 600 directly, avoiding the excessive consumption of the phone's battery caused by taking the phone out in cold environments.
[0070] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0071] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
