Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic mobile terminal. Background Art

[0002] Electronic mobile terminals are indispensable tools in people's modern life, such as mobile phones, tablet computers and other electronic products. Current electronic mobile terminals can generally be charged quickly, that is, they can charge as much electricity as possible in a short time to meet the user's needs. However, the lithium batteries in current electronic mobile terminals are prone to heat up during fast charging at room temperature or high temperature, and the heat of the battery will be transferred to the outer casing of the entire machine, resulting in a poor user experience. There are certain risks in fast charging of lithium-ion batteries in low temperature environments, because as the temperature decreases, the kinetic characteristics of the battery's graphite negative electrode will deteriorate, and the electrochemical polarization of the negative electrode will be significantly aggravated during charging. The precipitated metallic lithium is easy to form lithium dendrites and penetrate the diaphragm, resulting in a micro short circuit between the positive and negative electrodes, thereby affecting the performance and service life of the battery, and even explosion in severe cases.

[0029] The following will refer to Figure 1 and Figure 2 to describe the electronic mobile terminal according to some embodiments of the present application.

[0030] The present application provides an electronic mobile terminal. As Figure 1 and Figure 2 shown, the electronic mobile terminal includes a whole machine housing 9, a battery 8, and a composite adhesive tape. The battery 8 and the composite adhesive tape are both disposed inside the whole machine housing 9, and the composite adhesive tape is disposed between the battery 8 and the whole machine housing 9; the composite adhesive tape includes a heat insulation layer 3 and a first heating layer 1. The first heating layer 1 is stacked on one side of the heat insulation layer 3. The side of the first heating layer 1 facing away from the heat insulation layer 3 faces the battery 8 and is in contact with the surface of the battery 8. The side of the heat insulation layer 3 facing away from the first heating layer 1 faces the whole machine housing 9 and is in contact with the whole machine housing 9.

[0031] The first heating layer 1 can generate heat to heat the battery 8. The heat insulation layer 3 is made of a heat insulation material and has good heat insulation performance, which can effectively block heat transfer; therefore, in a low-temperature environment, when the battery 8 is charging, the battery 8 can be heated through the first heating layer 1, so that the battery 8 can quickly reach the temperature condition for high-current charging in a low-temperature environment, thereby ensuring the safety of fast charging of the battery 8. And through the heat insulation layer 3, the heat of the first heating layer 1 can be effectively blocked from being transferred to the whole machine housing 9 to avoid the whole machine housing 9 from getting hot and affecting the user experience; at the same time, in a normal-temperature or high-temperature environment, when the battery 8 generates heat, the heat insulation layer 3 can also effectively block the heat conduction of the battery 8 to the whole machine housing 9 to avoid the whole machine housing 9 from getting hot and affecting the user experience.

[0032] In an embodiment of the present application, preferably, the composite adhesive tape further includes a second heating layer 2. The second heating layer 2 is stacked on the side of the heat insulation layer 3 facing away from the first heating layer 1. The heat insulation layer 3 is in contact with the whole machine housing 9 through the second heating layer 2; the second heating layer 2 can generate heat. When the external environment temperature is relatively low, the whole machine housing 9 can be heated through the second heating layer 2, so that the electronic mobile terminal can actively generate heat and be used as a "warming baby" to heat external objects, for example, when the electronic mobile terminal is a mobile phone, when the user holds the mobile phone, the mobile phone can actively generate heat through the second heating layer 2 to warm the user's hand.

[0033] At the same time, since an insulating layer 3 that blocks heat transfer is provided between the first heating layer 1 and the second heating layer 2, the composite adhesive tape can achieve two-way unilateral heating, that is, the heat generated by the first heating layer 1 can be transferred to the battery 8 on the same side to heat the battery 8, but will not be transferred to the side of the second heating layer 2 to cause a significant impact on the temperature of the entire machine casing 9. Similarly, the heat generated by the second heating layer 2 can be transferred to the entire machine casing 9 to heat the entire machine casing 9, but will not be transferred to the side of the first heating layer 1 to cause a significant impact on the temperature of the battery 8.

[0034] In one embodiment of the present application, preferably, the composite adhesive paper also includes a first adhesive layer 4 and a second adhesive layer 5, wherein the first adhesive layer 4 is stacked between the first heating layer 1 and the thermal insulation layer 3, so that the first heating layer 1 is bonded and fixed to the thermal insulation layer 3 through the first adhesive layer 4; the second adhesive layer 5 is stacked between the second heating layer 2 and the thermal insulation layer 3, so that the second heating layer 2 is bonded and fixed to the thermal insulation layer 3 through the second adhesive layer 5.

[0035] In this embodiment, preferably, both the first adhesive layer 4 and the second adhesive layer 5 are insulating adhesive layers with good thermal insulation performance. For example, both the first adhesive layer 4 and the second adhesive layer 5 are glass fiber double-sided adhesives, thereby further blocking the heat transfer between the two sides of the thermal insulation layer 3, that is, blocking the heat of the first heating layer 1 and the battery 8 from transferring to the whole machine housing 9, and also blocking the heat of the second heating layer 2 from transferring to the battery 8.

[0036] In one embodiment of the present application, preferably, the composite adhesive paper also includes a third adhesive layer 6 and a fourth adhesive layer 7, the third adhesive layer 6 is stacked on the side of the first heating layer 1 away from the thermal insulation layer 3, and the fourth adhesive layer 7 is stacked on the side of the second heating layer 2 away from the thermal insulation layer 3, so that the first heating layer 1 is bonded to the surface of the battery 8 through the third adhesive layer 6, and the second heating layer 2 is bonded to the entire machine casing 9 through the fourth adhesive layer 7, so that the composite adhesive paper is stably fixed between the surface of the battery 8 and the entire machine casing 9.

[0037] In this embodiment, preferably, the third adhesive layer 6 and the fourth adhesive layer 7 are both thermally conductive adhesive layers with good thermal conductivity.

[0038] By using thermally conductive adhesive as the third adhesive layer 6, when the first heating layer 1 heats the battery 8, the heat released by the first heating layer 1 can be quickly transferred to the battery 8, so that the battery 8 quickly reaches the temperature condition for high-current charging.

[0039] By using thermally conductive adhesive as the fourth adhesive layer 7, the heat released by the second heating layer 2 can be quickly transferred to the entire machine casing 9 when heating the entire machine casing 9, so as to quickly heat the entire machine casing 9 to a predetermined temperature, so that the electronic mobile terminal can be used as a "hot pack".

[0040] Further preferably, the third adhesive layer 6 and the fourth adhesive layer 7 are 3M double-sided adhesives. The 3M double-sided adhesives not only have good thermal conductivity but also have good insulation properties, thereby enabling insulation between the composite adhesive paper and the battery 8 and other electrical components within the electronic mobile terminal.

[0041] In this embodiment, preferably, the thicknesses of the third adhesive layer 6 and the fourth adhesive layer 7 are respectively 0.05 mm - 0.15 mm.

[0042] By making the third adhesive layer 6 have a relatively thin thickness, the heat transfer efficiency between the first heating layer 1 and the battery 8 can be improved to a certain extent, so that the battery 8 can be quickly heated by the first heating layer 1, enabling the battery 8 to quickly reach the temperature condition for high-current charging.

[0043] By making the fourth adhesive layer 7 have a relatively thin thickness, the heat transfer efficiency between the second heating layer 2 and the whole machine housing 9 can be improved to a certain extent, so that the whole machine housing 9 can be quickly heated by the second heating layer 2, enabling the electronic mobile terminal to be used as a "warm baby" to heat external objects.

[0044] In an embodiment of the present application, preferably, the heat insulation layer 3 is an aerogel felt layer, so that the heat insulation layer 3 has good heat insulation performance. Thus, when the first heating layer 1 heats the battery 8, the heat generated by the first heating layer 1 is blocked from being transferred to the side of the second heating layer 2 through the heat insulation layer 3. When the second heating layer 2 heats the whole machine housing 9, the heat generated by the second heating layer is blocked from being transferred to the side of the first heating layer 1 through the heat insulation layer 3, enabling the composite adhesive paper to achieve two-way unilateral heating.

[0045] In an embodiment of the present application, preferably, a heating circuit, such as a resistance wire, is provided on the first heating layer 1. When the heating circuit is energized, the heating circuit can generate heat to heat the battery 8. A wiring terminal is provided on the side of the first heating layer 1. The heating circuit is electrically connected to the wiring terminal, and at the same time, the wiring terminal is electrically connected to the protection board of the battery 8, so as to supply power to the heating circuit of the first heating layer 1 through the battery 8 to make it generate heat, and at the same time, control the power on and off of the first heating layer 1.

[0046] In addition, in addition to being electrically connected to the battery 8 protection board, the wiring terminal can also be electrically connected to the main board of the electronic mobile terminal, so that the wiring terminal is electrically connected to the battery 8 through the main board, so as to control the power on and off between the mobile phone battery 8 and the first heating layer 1 through the main board.

[0047] The second heating layer 2 has the same structure as the first heating layer 1, and also includes a heating circuit and a wiring terminal, which will not be elaborated here.
