Detailed ways

As mentioned above, the utility model provides an improved casing of a portable electronic device, which utilizes the integration of the lower casing and the fan casing of the portable electronic device during production, so as to further reduce the production cost of the portable electronic device .

Please refer to FIG. 1 , which shows an inner surface view of a lower casing of a portable electronic device according to an embodiment of the present invention. An arc wall is designed on the inner surface of the lower casing 100 of the portable electronic device as the radial casing 102 of the bare fan assembly 104 . When the upper case (not shown in the figure) of the portable electronic device is assembled with the lower case 100, the upper case will fit on the radial case 102 to form a complete case of the bare fan assembly 104, This enables the bare fan assembly 104 to perform its cooling function. The radial housing 102 has a radial opening 102 a as an air outlet of the bare fan assembly 104 . The above-mentioned design enables the shell of the bare fan assembly 104 to be integrated on the upper and lower shells of the portable electronic device, thereby avoiding the cost of additionally manufacturing the shell of the bare fan assembly. This design is especially suitable for plastic casings manufactured by injection molding, because the cost of mold opening for injection molding is very expensive. When the radial housing 102 and the lower housing 100 are integrally formed, only one mold can be used to manufacture both, which saves the cost of designing a mold for the housing of the bare fan assembly 104 . The bare fan assembly 104 is used in the portable electronic device to increase the effect of active heat dissipation, so the radial opening 102a of the radial housing 102 needs to be aligned with the plurality of heat dissipation through holes (106a; 106b) of the lower housing 100 to The heat dissipation effect of the bare fan assembly 104 is brought into play. In the area of the lower case 100 corresponding to the heat dissipation through holes (106a; 106b), heat dissipation fins can be installed, and the airflow generated by the bare fan assembly 104 can be used to increase heat dissipation performance.

In this embodiment, there is a gap 103 between the radial housing 102 and the lower housing 100 except for the portion of the radial opening 102a. Between the radial housing 102 and the lower housing 102 there are a plurality of connecting pieces 102b spanning the gap 103 to connect the radial housing 102 and the lower housing 102, so that the radial housing 102 can be stably connected to the lower housing 100 .

Please refer to FIGS. 2 and 3 at the same time. FIG. 2 shows the outer surface view of the lower case in FIG. 1 , and FIG. 3 shows the state where the fan device in FIG. 2 is separated from the lower case. A cover 105 can be designed on the outer surface (or bottom surface) of the lower casing 100 in the area of the bare fan assembly 104 . The cover 105 has a plurality of heat dissipation through holes 105 a, and when the cover 105 is on the outer surface of the lower casing 100 , the heat dissipation through holes 105 a are used as air inlets of the bare fan assembly 104 .

In this embodiment, the bare fan assembly 104 is loaded into or removed from the bottom of the lower casing 100 . The advantage of this design is that it is not necessary to disassemble the upper and lower casings of the portable electronic device when replacing the bare fan assembly 104 , reducing the man-hours required for replacing the bare fan assembly 104 .

The bare fan assembly 104 includes a fan frame 104a, a motor 104b and a fan blade 104c. The motor 104b (shown in dashed lines) is fixed on the central area of the fan frame 104a. The fan blade 104c is connected to the motor 104b and is driven to rotate. The edge of the fan frame 104a has a plurality of locking holes 104d, and the lower casing 100 also has corresponding locking holes 102c, so as to lock the bare fan assembly 104 to the lower casing 100 with screws. The fan frame 104a has a plurality of openings 104e located in its non-central area, and the openings 104e are located in the axial direction of the fan blade 104c. The opening 104e serves as an air inlet of the bare fan assembly 104 .

In this embodiment, the fan blade 104c of the bare fan assembly 104 is a centrifugal fan blade, so the airflow enters from the axial direction of the bare fan assembly 104 (through the heat dissipation through hole 105a and the opening 104e), and flows from the bare fan assembly 104. Radial air outlet of fan assembly 104 (air outlet through heat dissipation vias (106a, 106b)). However, the present invention does not limit the type of blades of the bare fan assembly. If other types of blades (such as axial flow blades) are required, the housing can also be integrated on the lower housing of the portable electronic device. .

Please refer to FIGS. 4 and 5 at the same time. FIG. 4 shows an inner surface view of a lower case of a portable electronic device according to another embodiment of the present invention. FIG. 5 is a diagram illustrating a state in which the fan device of FIG. 4 is separated from the lower casing. The difference between this embodiment and the embodiment shown in Figs. 1, 2 and 3 lies in the way of connection between the radial housing and the lower housing. In this embodiment, there is no gap connection between the radial housing 104' and the lower housing 100'. In the embodiments shown in Figures 1, 2, and 3, there is a gap 103 between the radial housing 102 and the lower housing 100 (except the radial opening 102a), and they are connected to each other across the gap 103 by a plurality of connecting pieces 102b . In Fig. 5, the center of the radial housing 102' has a positioning column 102d, which can be used to locate the position of the bare fan assembly 104' in the radial housing 102'. In addition, when replacing the bare fan assembly 104', the upper and lower housings of the portable electronic device need to be disassembled for replacement, which is different from the above-mentioned embodiments in Figures 1, 2 and 3.

From the above-mentioned embodiments of the present invention, it can be seen that the housing of the portable electronic device of the present invention utilizes "the design of integrally forming the radial housing of the fan and the lower housing" to save the cost of designing molds and further reduce the The purpose of the production cost of portable electronic devices.

Although the present utility model has been disclosed as above in terms of implementation, it is not intended to limit the present utility model. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the scope of protection of the present utility model should be defined by the scope of the appended patent application as the criterion.
