Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4 of the specification, an embodiment of the present invention provides a smart watch, which includes a middle frame 200, a display screen assembly (not shown), a double-sided motherboard 100, a battery (not shown), and a bottom cover (not shown), wherein the bottom cover is provided with a sensor assembly (not shown). Wherein, the middle frame 200 is internally provided with a clapboard 200a which divides the middle frame 200 into two parts, the double-sided mainboard 100 is arranged in the upper cavity of the middle frame 200, and the display screen component is sealed at the cavity opening of the upper cavity of the middle frame 200. The battery is arranged in the lower cavity of the middle frame 200, and the bottom cover is sealed at the cavity opening of the lower cavity of the middle frame 200. The middle of the partition board 200a is hollowed out for the battery and sensor assembly to be connected to the double-sided motherboard 100 through the flexible flat cable.
In this embodiment, the double-sided motherboard 100 includes a double-sided PCB substrate 110, and electronic components are mounted on both sides of the double-sided PCB substrate 110. Four mounting holes 110a are uniformly distributed along the circumferential direction of the double-sided PCB substrate 110, a supporting column 120 is inserted and connected in each mounting hole 110a, the upper end of each supporting column 120 extends outwards from the front surface of the double-sided PCB substrate 110, and the extending height of each supporting column is higher than that of an electronic component mounted on the front surface of the double-sided PCB substrate 110. The lower ends of the supporting pillars 120 extend outward from the reverse side of the double-sided PCB substrate 110, and the extending height is higher than that of the electronic component mounted on the reverse side of the double-sided PCB substrate 110.
Two semicircular first positioning grooves 110b and a rectangular second positioning groove 110c are formed in the outer edge side wall of the double-sided PCB substrate 110, and the two first positioning grooves 110b and the second positioning grooves 110c are uniformly distributed along the circumferential direction of the double-sided PCB substrate 110. Correspondingly, a semicircular first protrusion 200b and a rectangular second protrusion 200c corresponding to the first positioning groove 110b are formed on the inner wall of the middle frame 200. The first positioning groove 110b and the second positioning groove 110c with different shapes arranged on the outer edge side wall of the double-sided PCB substrate 110 can play a fool-proof role.
During assembly, the first positioning groove 110b and the second positioning groove 110c of the double-sided PCB substrate 110 are aligned with the first protrusion 200b and the second protrusion 200c and then are installed in the upper cavity of the middle frame 200, so that the lower end of the supporting column 120 abuts against the partition board 200a of the middle frame 200, and the double-sided PCB substrate 110 and the partition board 200a keep a certain interval to avoid the electronic component on the back side of the double-sided PCB substrate 110; then, the display screen assembly is sealed at the cavity opening of the cavity at the upper part of the middle frame 200, and the upper end of the supporting column 120 provides support for the display screen assembly and enables the display screen assembly and the electronic components on the front surface of the double-sided PCB substrate 110 to keep a certain interval to avoid the electronic components.
