Background technique

At present, most electronic devices such as tablet computers or smart phones usually adopt a wired charging method to provide current to the electric storage unit of the electronic device for charging, so as to provide the electric energy required for the operation of the electronic device. In recent years, compared with wired charging technology, wireless charging technology also has the characteristics of convenience and versatility, so it is gradually favored by consumers. The wireless charging technology is mainly realized by using the principle of electromagnetic induction. Generally speaking, a charging coil is provided in a wireless charging device, and an induction coil is provided in an electronic device. The charging coil can generate an electromagnetic signal, and the induction coil is adapted to generate current after sensing the electromagnetic signal sent from the charging coil, so as to charge the electric storage unit in the electronic device.

Generally speaking, the electronic device needs to lean on the wireless charging stand when performing wireless charging, so that the induction coil corresponds to the charging coil on the wireless charging stand. In addition, due to the short effective inductive charging distance of wireless charging, the side where the induction coil in the electronic device is located must be quite close to the side where the charging coil is located in the wireless charging stand. At this time, the heat generated by the electromagnetic coupling between the charging coil and the induction coil cannot be dissipated quickly, but is accumulated on the casing of the tablet computer or smart phone, resulting in an overheating of the casing. In this way, not only will the user feel hot when touching the case, but the electronic components inside the electronic device will also be affected by the high temperature and malfunction or be damaged.

The seat body 110 has an air guide 111 , a bearing portion 112 , a supporting portion 113 and a backboard portion 114 , wherein the bearing portion 112 is connected to the backboard portion 114 , and the supporting portion 113 protrudes from the backboard portion 114 . Here, the carrying portion 112 is, for example, a groove on the base body 110 , and the back plate portion 114 is, for example, an inclined surface connecting the aforementioned groove on the base body 110 , so that when the electronic device 10 is mounted on the base body 110 , it can resist Leaning against the supporting portion 113 and acting as a stopper through the supporting portion 112 , the electronic device 10 tilted on the seat body 110 is prevented from slipping, thereby improving the convenience and stability of the user when operating the electronic device 10 .

FIG. 4 is a schematic cross-sectional view of FIG. 2 along the section line A-A. Please refer to FIG. 1 and FIG. 4. In this embodiment, the support portion 113 may include at least one support pad 113a (two are schematically shown in FIG.

When the electronic device 10 is placed on the base body 110 , the electronic device 10 leans against the carrying portion 112 and the support pad 113 a. At this time, the support pad 113 a can prop up the electronic device 10 , so that the communication path P of the air guide opening is defined between the electronic device 10 , the back plate part 114 and the charging coil module 120 .

The charging coil module 120 protrudes from the back plate portion 114 , wherein the charging coil module 120 may include a charging coil 121 and a housing 122 , and the charging coil 121 is disposed in the housing 122 . Here, the shell 122 is, for example, integrally formed on the back panel 114 , or fixed on the back panel 114 by gluing or locking, which is not limited by the present invention. When the electronic device 10 is placed on the base body 110 , the position of the induction coil 11 corresponds to the position of the charging coil 121 , and the electronic device 10 abuts against the supporting part 112 and the supporting part 113 . There is a gap between the backboard part 114 and the charging coil module 120 and the electronic device 10 , and a first gap distance D1 is maintained between the backboard part 114 and the electronic device 10 . In detail, since the support pad 113a can prop up the electronic device 10, so that the communication path P of the air guide port is defined between the electronic device 10, the back plate part 114 and the charging coil module 120, so the first gap distance D1 is, for example, the same as the support pad 113a. The first thicknesses T1 of the pads 113a are equal.

On the other hand, the first thickness T1 of the support pad 113a is, for example, greater than the second thickness T2 of the shell 122, so the shell 122 of the charging coil module 120 protruding from the back plate 114 will not contact the electronic device 10 and retain the second thickness T2.

Specifically, the air guide port 111 is disposed corresponding to the corresponding fan 130 and is located on the back plate portion 114 . On the other hand, the seat body 110 also has a groove 115 , wherein the groove 115 is located on the back plate portion 114 and communicates with the air guide opening 111 . Accordingly, when the fan 130 is in operation, the airflow AF can sequentially pass through the corresponding air guide opening 111 and the groove 115 to blow the air guide opening communication path P.
