[0001] The utility model relates to the technical field of mobile power supplies, in particular to a highly safe mobile power supply. Background Art

[0002] A mobile power bank, also known as a power bank, a mobile power bank or a Mobile Power Bank / Pack, is a portable electronic device that is mainly used to charge handheld mobile devices (such as mobile phones, tablet computers, digital cameras, etc.) without an external power source. It contains a large-capacity battery for storing electrical energy and is equipped with a circuit that stabilizes the output voltage to ensure that it can safely charge different devices.

[0003] When the mobile power bank is working, the chemical energy in the battery is converted into electrical energy and output through the circuit. In this process, due to the impedance of the circuit and the energy conversion efficiency is not 100%, part of the electrical energy will be lost in the form of heat energy. When the mobile power bank is charging the device, it needs to convert the battery voltage into a voltage suitable for the device (such as 5V). This step-up and step-down process will also generate energy loss and corresponding heat.

[0004] Therefore, during the use of the mobile power supply, due to the inevitable energy loss in the process of power conversion and transmission, if it is used for a long time, the mobile power supply may heat up abnormally, become hot to use, and may cause damage to internal components, posing certain safety hazards.

[0029] Example

[0030] A highly safe mobile power source, see Figures 1 to 3, which includes a shell 10 and a battery body 30 disposed in the shell 10, and further includes a heat-conducting component 20, the shell 10 includes a first side surface 11, a second side surface 12 and an enclosure surface 13, the first side surface 11 and the second side surface 12 are arranged opposite to each other, the enclosure surface 13 is arranged between the first side surface 11 and the second side surface 12 to form an inner cavity for accommodating the battery body 30, and the heat-conducting component 20 is connected between the battery body 30 and the enclosure surface 13; the first side surface 11 and / or the second side surface 12 are provided with a heat-insulating layer 40. In this embodiment, by adding a heat-conducting component 20 to the mobile power supply and directly connecting the battery body 30 and the enclosure surface 13 of the shell 10, the heat conduction efficiency can be effectively improved, so that the heat generated by the battery when working can be quickly transferred and dispersed to the surface of the shell 10, thereby reducing the local high temperature of the battery and circuit board area and reducing the risk of overheating caused by long-term use. In this embodiment, a heat-insulating layer 40 is arranged on the first side 11 or / and the second side 12, so as to form a heat-isolating barrier outside the mobile power supply. Even if the internal battery and circuit generate heat, the heat-insulating layer 40 can prevent the heat from being quickly transferred to the part held by the user, thus avoiding the phenomenon of being scalded during use, significantly improving the user's safety experience, and protecting the internal electronic components from heat damage, thereby extending the service life of the mobile power supply. Through the optimized thermal management design, the battery performance degradation or circuit failure that may be caused by heat accumulation is reduced, ensuring that the mobile power supply can stably output power in a variety of working environments, providing continuous and safe charging services for mobile devices, and enhancing the reliability of the product and user satisfaction. In combination with the above-mentioned improvement measures, the high-safety mobile power supply is not only physically safer and more reliable, reducing safety hazards, but also because of the good heat dissipation performance, the product will not be deformed or discolored due to overheating in appearance, maintaining the aesthetics, and improving the user's overall comfort and trust.

[0031] Combination Figures 1 to 3As shown, the heat-conducting assembly 20 includes a heat-conducting member 21 and a heat sink 22, one end of the heat-conducting member 21 is connected to the battery body 30, and the other end of the heat-conducting member 21 is connected to the heat sink 22, and the enclosing surface 13 is provided with a mounting hole 14 for mounting the heat sink 22, so that the heat sink 22 is at least partially exposed to the outer surface of the shell 10. Specifically, the heat-conducting member 21 can be a heat pipe or a heat-conducting gel, so that the heat generated by the battery body 30 can be quickly transferred to the heat sink 22. The heat sink 22 can be set with copper material. In this embodiment, the battery body 30 and the heat sink 22 are directly connected by the heat-conducting member 21, forming an efficient heat conduction path, which can quickly transfer the heat energy generated by the battery when working to the heat sink 22. This design greatly improves the efficiency of heat energy transfer, reduces the loss of heat energy during conduction, and ensures that the heat can be processed in time. The design in which the heat sink 22 is partially exposed on the outer surface of the shell 10 makes full use of the principle of air convection, increases the contact area with the external environment, speeds up the heat dissipation from the mobile power supply to the air, effectively reduces the surface temperature of the mobile power supply, and maintains a low temperature rise even under high-load working conditions, thereby improving safety and comfort during use.

[0032] In this embodiment, the heat sink 22 is arranged around the battery body 30, and the mounting holes 14 are arranged circumferentially along the enclosure surface 13. The mounting holes 14 are arranged on the enclosure surface 13 for fixing the heat sink 22. This design not only meets the functional requirements, but also takes into account the overall structural layout and appearance aesthetics of the product, so that the installation of the heat sink component is stable and not obtrusive, maintaining the compactness and aesthetics of the mobile power supply. At the same time, this design makes full use of the principle of air convection, increases the contact area with the external environment, speeds up the speed of heat dissipation from the mobile power supply to the air, and effectively reduces the surface temperature of the mobile power supply.

[0033] In this embodiment, heat dissipation teeth are provided on the side of the heat sink 22 away from the battery body 30, which further promotes the heat exchange between the air and the heat sink 22 by increasing the total area of ​​the heat dissipation surface. The structural design of the heat dissipation teeth can guide the air flow, form more turbulence, accelerate the heat dissipation from the heat sink 22 to the surrounding environment, and greatly improve the heat dissipation efficiency. The layout of the heat dissipation teeth can optimize the airflow guidance around the housing 10, so that the airflow under natural convection or fan assistance can pass through the heat dissipation tooth gap more smoothly and take away more heat, which is particularly critical for improving the overall cooling effect, especially when the mobile power supply has high power output or the ambient temperature is high.

[0034] like Figures 1 to 3As shown, the heat insulation layer 40 is located on the inner side of the shell 10, one side of the heat insulation layer 40 is connected to the battery body 30, and the other side of the heat insulation layer 40 is connected to the first side 11 or the second side 12; the cross section of the heat insulation layer 40 is wavy or corrugated. The heat insulation layer 40 is in close contact with the battery body 30 and the first side 11 or the second side 12 of the shell 10, forming a direct heat isolation barrier, which effectively prevents the heat generated by the battery when working from being conducted to the user's hand-held part. This design significantly improves the heat insulation effect, and even under long-term high-load use, the surface temperature of the shell can be kept appropriate to avoid hot hands. The heat insulation layer 40 adopts a wavy or corrugated cross-section design, which not only increases the rigidity of the material itself, but also improves the overall structural strength and stability of the shell 10. This structural design can withstand external pressure and impact while reducing weight, protect the internal battery from damage, and extend the service life of the mobile power supply. The wavy or corrugated insulation layer 40 actually increases the distance between the battery and the shell 10 through its concave-convex structure without significantly increasing the volume of the mobile power supply, providing an additional channel for hot air circulation, indirectly assisting heat dissipation, improving internal temperature distribution, and reducing heat accumulation.

[0035] In this embodiment, the thermal insulation layer 40 is thermal insulation silicone. Silicone has the characteristic of low thermal conductivity, which can very effectively isolate the heat generated by the battery when it is working, prevent the heat from being transferred to the mobile power supply shell, keep the surface temperature of the shell moderate, and ensure that the user can hold it safely and comfortably. In other embodiments, the thermal insulation layer 40 is a vacuum insulation layer 40. The vacuum insulation layer 40 uses the extremely low thermal conductivity in a vacuum state, and its thermal conductivity is much lower than that of traditional insulation materials. It can extremely effectively isolate the transfer of battery heat energy to the shell 10 and the external environment, keep the surface temperature of the mobile power supply shell low, and improve the comfort and safety of the user holding it. The vacuum insulation technology allows the thermal insulation layer 40 to provide excellent thermal insulation performance while maintaining an extremely light weight, which helps to reduce the weight of the entire mobile power supply and improve portability.

[0036] like Figures 1 to 3 As shown, in this embodiment, the first side surface 11 and / or the second side surface 12 are provided with a gripping portion 16 in a circumferential direction, and the gripping portion 16 protrudes from the enclosure surface 13. By providing the gripping portion 16 in a circumferential direction on the first side surface 11 and / or the second side surface 12, an ergonomic gripping area is provided for the user, which increases the friction and comfort when holding the power bank, and ensures a stable grip to prevent accidental slipping even if the hands are sweating or the surface of the mobile power bank is slightly slippery. The design of the gripping portion 16 protruding from the enclosure surface 13 allows the user to keep a certain distance between the fingers and the heat sink 22 when holding the mobile power bank, effectively avoiding direct contact with the overheated surface, and improving the safety and comfort during use.

[0037] In this embodiment, the first side 11 is provided with the gripping portion 16 and the heat insulating layer 40, and the second side 12 is provided with the wireless charging module 15. The second side 12 is provided with the wireless charging module 15, which realizes the wireless charging function of the mobile power supply. The user only needs to place the device that supports wireless charging on it to start charging, without the need for additional cables, which increases the convenience and flexibility of use. This design makes rational use of the two-dimensional space of the mobile power supply and makes the product functions more diversified. The first side 11 integrates the gripping portion 16 and the heat insulating layer 40, which not only ensures the comfort and safety of the user when holding the mobile power supply, avoids discomfort due to long-term holding or the feeling affected by the heating of the device, but also ensures the safety of use at high power output, and improves the overall user experience.

[0038] In this embodiment, the outer surface of the first side surface 11 is in an arc shape, and the outer surface of the first side surface 11 is also provided with anti-skid patterns. The arc-shaped outer surface fits the curve of the hand better, and can provide a natural and comfortable grip whether it is held with one hand or two hands, reducing the fatigue caused by long-term holding. Adding anti-skid patterns on the outer surface is a practical and careful design consideration. Anti-skid patterns can effectively increase the friction of the contact surface, ensuring that the user holds it firmly even in sweaty hands or humid environments, preventing accidental slipping, thereby protecting the safety of the device and the user.

[0039] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
