[0046] With the rapid development of mobile communication technology and consumer electronic products, smart phones and other portable electronic products have become an indispensable part of people's daily lives. However, the normal operation of these devices depends on the good working condition of their built-in batteries. Especially in cold climatic conditions, such as during winter outdoor activities, low temperature will have a significant negative impact on common portable device batteries such as lithium-ion batteries. Research shows that in an environment of minus 5 degrees Celsius, the power consumption of the same mobile phone will increase to 1.7 times that at standard room temperature (about 20 degrees Celsius); and when the ambient temperature further drops to minus 30 degrees Celsius, most of the tested mobile phones will experience automatic shutdown, that is, the so-called "power loss" problem. This phenomenon greatly limits the usability of electronic products under low temperature conditions and brings great inconvenience to the user experience.

[0047] Traditional solutions often focus on improving the battery material itself or optimizing the battery management system, but these methods usually are difficult to achieve significant effects in a short time and may be accompanied by an increase in cost. In addition, some auxiliary devices on the market, such as external battery packs or heating pads, although they can alleviate the problems brought by low temperature to a certain extent, most of them rely on chemical reaction heat release, have problems such as unstable temperature control, inconvenient use, etc., and may have certain safety hazards.

[0048] In view of this, there is an urgent need for a new solution to address the problem of the decline in battery performance of electronic products in low-temperature environments. An ideal solution should be able to effectively maintain the temperature of the environment around the battery, ensure that the battery can still maintain a good working state under low-temperature conditions, and at the same time, the solution should also have the characteristics of being easy to use, safe and reliable, etc.

[0049] For this purpose, as Figures 1 to 8 shown, the heating device proposed by the present utility model includes a main body 100 and a self-controlled temperature heating component 200 connected to the main body 100. Among them, the main body 100 is used to be connected to an electronic product, and the self-controlled temperature heating component 200 includes a self-controlled temperature heating sheet 210 and an energization circuit 220. The position of the self-controlled temperature heating sheet 210 corresponds to the position of the driving power supply of the electronic product. The energization circuit 220 is electrically connected to the self-controlled temperature heating sheet 210. In application, the energization circuit 220 is used to be connected to a power supply and supply power to the self-controlled temperature heating sheet 210, driving the self-controlled temperature heating sheet 210 to heat up to a preset temperature and maintain at the preset temperature to heat the driving power supply. It should be noted that by designing the self-controlled temperature heating component 200 corresponding to the position of the driving power supply of the electronic product, the temperature around the driving power supply can be quickly increased to a preset range, such as between 40°C and 50°C, in a low-temperature environment, thereby effectively improving the working state of the driving power supply. It can not only improve the performance of the driving power supply under low-temperature conditions and reduce the occurrence of power-off phenomena, but also ensure the safety and stability of the battery during the heating process due to the characteristics of its uniform heating surface and constant temperature; in addition, the design of this device is convenient for installation and disassembly, has strong adaptability, and is suitable for use with various types of electronic products.

[0050] Refer to Figure 1, in some embodiments of the present utility model, the main body 100 includes an annular portion 110. The annular portion 110 is arranged around the peripheral wall of the electronic product. The annular portion 110 is detachably sleeved with the electronic product, which not only simplifies the installation and disassembly steps of the user, improves the convenience of use, but also allows the user to replace or adjust the heating device at any time according to actual needs, enhancing the flexibility and practicality of the device. Moreover, the annular portion 110 can protect the electronic product, acting as a protective cover to protect the electronic product from being scratched, dropped, etc. In some embodiments, the main body 100 includes a supporting portion 120. The self-controlled temperature heating sheet 210 is installed on the inner or outer side of the supporting portion 120, and the supporting portion 120 is adapted to abut against the outer wall of the electronic product for heat conduction. Such a structural design is conducive to the effective conduction of heat, ensuring that the heat generated by the self-controlled temperature heating sheet 210 can be quickly transferred to the driving power supply of the electronic product, thereby improving the heating efficiency and better protecting the driving power supply of the electronic product from the influence of low temperature. It is easy to understand that the supporting portion 120 can not only support the self-controlled temperature heating sheet 210, but also play the role of supporting the electronic product. Optionally, the supporting portion 120 is a flat structure, which can better support the planar self-controlled temperature heating sheet 210. In some embodiments, the annular portion 110 surrounds the outer peripheral edge of the supporting portion 120 and is integrally formed with the supporting portion 120. Specifically, as Figure 1 shown, artificial leather 500 is provided on the outer side wall of the supporting portion 120, and the self-controlled temperature heating sheet 210 is directly installed on the artificial leather 500. For example, the self-controlled temperature heating sheet 210 is sewn on the artificial leather 500. Referring again to Figure 3 and Figure 4 , the self-controlled temperature heating sheet 210 is pressed between two partition plates 510, and the artificial leather 500 is laminated on the outermost partition plate 510 and fixedly connected thereto.

[0051] As Figure 1 shown, the power supply is arranged outside the main body 100, and the self-controlled temperature heating sheet 210 is powered by an external power supply (not shown in the figure) for heating. In application, an external power supply needs to be directly plugged in for power supply. Further, in some embodiments of the present utility model, the annular portion 110 is provided with a clearance groove 1101. The clearance groove 1101 is used for the electrical interface 230 of the power supply to pass through, so as to energize the power-on circuit 220, ensuring the availability of the power supply and guaranteeing the normal operation of the device. At the same time, the design of the clearance groove 1101 also takes into account not affecting the normal use of the electronic product, improving the rationality of the overall design. In some embodiments, the clearance groove 1101 is provided on the bottom wall of the annular portion 110; in some embodiments, the clearance groove is provided on the side wall of the annular portion (not shown in the figure); in some embodiments, the clearance groove is provided on the top wall of the annular portion (not shown in the figure).

[0052] In some embodiments of the present utility model, the power supply is installed inside the main body 100, and, referring toFigure 5 , a control button 102 is provided on the outer wall of the main body 100. The control button 102 is electrically connected to the power supply and is used to control the on and off of the power supply. Furthermore, the user can easily operate the on and off of the power supply through the control button 102, enhancing the user's operation experience and the controllability of the power supply. In this regard, a circuit board 700 is provided inside the main body 100. The circuit board 700 integrally controls the power supply through the control button 102. And, an electrical interface 230 is provided on the circuit board 700 and extends out from the installation groove 101. The electrical interface 230 is used to connect to an external power source to charge the power supply. Optionally, the electrical interface 230 can be various common interfaces such as Microsoft USB, Type-C, etc. Referring again to Figure 2 , in some embodiments of the present invention, the power supply is a receiving coil 310, and the receiving coil 310 is charged by wireless charging. The wireless charging method not only eliminates the restraint of traditional charging cables, making the heating device more portable and easy to use, but also reduces the risk of damage that may be caused by frequent plugging and unplugging of the charging interface 230, and extends the service life of the product. In addition, a magnetic induction ring 311 is also provided inside the main body 100, which can assist in magnetic absorption charging. Referring again to Figure 5 and Figure 6 , in some embodiments of the present invention, the power supply is a storage battery. Optionally, the storage battery is a lithium battery. Correspondingly, the main body 100 is provided with an installation groove 101, and the storage battery is installed in the installation groove 101. And, the main body 100 is equipped with a heat conducting plate 400. One end face of the heat conducting plate 400 is used to cover the self-controlled temperature heating sheet 210, and the other end face is used to abut against the driving power source of the electronic product. The design of the storage battery enables the heating device to work independently of the power system of the electronic product itself, increasing the autonomy and flexibility of the heating device. In addition, the design of the heat conducting plate 400 further enhances the efficiency of heat conduction, ensuring that the driving power source can be fully heated and protected. In some embodiments, a detachable rear cover 600 is provided on the back side of the main body 100, which can conveniently perform maintenance and repair on the self-controlled temperature heating component 200 and the power supply. Specifically, the rear cover 600 is provided with positioning posts 610, and the back side of the main body 100 is provided with positioning grooves (not shown in the figure). The positioning posts 610 are conical structures and are adapted to be inserted and matched with the positioning grooves. And, the rear cover 600 is provided with fixing blocks 620, and the main body 100 is provided with fixing protrusions 103. A fixing groove with a closed setting is provided in the middle of the fixing block 620. During the insertion process of the rear cover 600 and the main body 100, the fixing block 620 deforms towards the center of the rear cover 600 and resets after being inserted in place. At this time, the fixing protrusion 103 is inserted into the fixing groove to fix the main body 100 and the rear cover 600.

[0053] In some embodiments of the present invention, such as Figure 7As shown in the figure, the self-controlled temperature heating sheet 210 includes a first PI film layer 211, a conductive layer 212, a plating layer 213, a PTC paste layer 214, and a second PI film layer 215 that are sequentially laminated. Such a structure not only provides excellent mechanical strength and electrical insulation performance, but also the plating layer 213 can prevent the conductive layer 212 from being oxidized. Moreover, the use of the PTC paste layer 214 ensures that the heating sheet has good self-controlled temperature characteristics, can automatically adjust the heat generation amount according to the ambient temperature change, avoid overheating phenomena, and ensure the safety and stability of the heating sheet during operation. Among them, the preset temperature is A, satisfying: 40° ≤ A ≤ 50°. This temperature range can not only effectively increase the working temperature around the drive power supply, but also will not cause damage to the drive power supply. By precisely controlling the temperature of the heating sheet, it is possible to ensure that the performance of the battery in a low-temperature environment is improved, extend the service life of the drive power supply of the electronic product, and provide a comfortable hand feeling temperature for the user. Specifically, the preset temperature is 45°. Reference can be made to the patent with the publication number of CN 109907878 A and the patent name of a rapid heating constant temperature hot compress element and its preparation method, as well as the patent with the publication number of CN 108503940 A and the patent name of a PTC organic composite material with a low Curie temperature point and its preparation method.
