FIG. 3 is a schematic diagram of an electronic device according to a preferred embodiment of the present invention. In this embodiment, the electronic device 300 is exemplified by a notebook computer having a first board body 310 and a second board body 320. The first board body 310 has a first electrical component (not shown). The second board 320 has a second electrical component. The first electrical component includes a display panel and a backlight module. The second electrical component includes a computer component, a battery, and a keyboard. The first plate body 310 is pivotally connected to the second plate body 320 through the pivot assembly 100. Therefore, the first plate body 310 can be relatively closed with the second plate body 320 or can be opened to the specific portion with respect to the second plate body 320. angle. As shown in FIG. 2, the pivot assembly 100 is provided with a cable 130 having a wire 133 having one end having a first joint 131 and the other end having a second joint 132. The first electrical component is electrically connected to the first connector 131, and the second electrical component is electrically connected to the second connector 132. The first electrical component and the second electrical component are transparent to the cable 130. They are electrically connected to each other.

As shown in FIG. 1 , the pivot assembly 100 includes a first fixing portion 110 and a second fixing portion 120 . The first fixing portion 110 includes a first fixing plate 111 and a shaft body 112 extending from one end of the first fixing plate 111. The surface of the shaft body 112 is recessed with a plurality of receiving grooves 113. The receiving groove 113 is formed by the shaft body 112. One end extends linearly to the other end and is parallel to the axial direction of the shaft body 112, and these accommodating grooves 113 are arranged in the axial direction and are circumferentially distributed on the surface of the shaft body 112.

The second fixing portion 120 includes a second fixing plate 121 and a ring body 122. One side of the second fixing plate 121 defines a fixing edge 125, and the ring body 122 extends from the fixing edge 125.

A portion of the shaft hole 123 is formed, and the end of the first ring wall 1221 is spaced apart from the fixed side 125 by a first opening 126. The second annular wall 1222 extends from the fixed edge 125 and is curled clockwise (opposite to the crimping direction of the first annular wall 1221) to form another portion of the shaft hole 123. The end of the second annular wall 1222 is spaced from the fixed edge 125. There is a second opening 127. In other words, the first ring wall 1221 and the second ring wall 1222 together form a shaft hole 123, and the shaft hole 123 corresponds to the shaft body 112, so that the shaft body 112 can pass through the shaft hole 123, and the shaft body 112 and the ring body The first fixing portion 110 and the second fixing portion 120 are pivotally connected to each other. At the same time, the friction generated by the surface of the shaft body 112 and the inner surface of the ring body 122 (that is, the hole wall of the shaft hole 123) can maintain the mutual opening angle of the first fixing portion 110 and the second fixing portion 120. Support.

The wire 133 is disposed to be disposed in the accommodating groove 113. In the embodiment, the depth of the accommodating groove 113 is greater than the thickness of the wire 133 or the radial diameter thereof, so that the wire 133 does not extend beyond the surface of the shaft body 112. This design considers that when the shaft body 112 is rotated in the shaft hole 123, it is necessary to avoid the possibility that the wire 133 and the hole wall of the shaft hole 123 rub against each other to damage the wire 133. As shown in FIG. 2, the wire 133 further includes a plurality of sub-wires 1331, 1332, and 1333, and the sub-wires 1331, 1332, and 1333 are respectively disposed. In the corresponding accommodating groove 113. Since the wires 133 are dispersed into the sub-wires 1331, 1332, and 1333, the thickness or the radial diameter of each of the sub-wires 1331, 1332, and 1333 can be greatly reduced as compared with the wires 133, and the sub-wire 1331 can be effectively avoided. 1,332, 1333 and the inner surface of the ring body 122 are rubbed. Preferably, the bottom of the accommodating groove 113 is also coated with a glue layer (not shown), and the glue layer is used for bonding the sub-wires 1331, 1332, and 1333 to be fixed at the bottom of the accommodating groove 113. In other embodiments, different engagement members, such as cassettes, may be employed to secure the wires in the receiving slots.

In addition, the first fixing plate 111 is provided with a plurality of first fixing holes 114, and the first fixing holes 114 correspond to the first fixing members (not shown). The second fixing plate 121 is provided with a plurality of second fixing holes 124. The second fixing holes 124 correspond to the second fixing member. The first fixing member and the second fixing member are screws, but are not limited thereto. The first fixing plate 111 is locked to the first plate body 310 and the second fixing plate 121 is locked to the second plate body 320 by the first fixing hole 111 and the second fixing hole 124. As a result, the first board body 310 and the second board body 320 of the electronic device 300 can be pivotally and electrically connected to each other by the pivot assembly 100.

Referring to FIG. 4 and FIG. 5, FIG. 4 is a schematic diagram of a first fixing portion according to another preferred embodiment of the present invention, and FIG. 5 is a pivot assembly of another preferred embodiment of the present invention. The schematic diagram of the pivot assembly 100 shown in FIG. 1 and FIG. 2 is different, and the difference is that the accommodating groove 113 and the accommodating groove 213 have different structures. As shown in FIG. 4, the first fixing portion 210 has a first fixing plate 211 and a shaft body 212 extending from one end of the first fixing plate 211, and the shaft body The receiving portion 213 is formed in a spiral shape around the surface of the shaft body 212. The shaft body 212 is also disposed in the ring body 122 of the second fixing portion 120. The wire 230 has a first joint 231, a second joint 232 and a wire 233 connected thereto. The wire 233 is disposed in the receiving groove 213. An advantage of this embodiment is that a substantially constant frictional force can be generated between the ring body 122 and the shaft body 212 during relative rotation of the first fixing portion 210 and the second fixing portion 120. In detail, since the accommodating groove 213 has a spiral relationship, the total area of the surface of the shaft body 212 and the inner surface of the ring body 122 is not affected by the opening of the ring body 122 regardless of the angle of rotation. The increase or decrease (as shown by the first opening 126 and the second opening 127 as indicated in FIG. 1) means that the total area in which the two are in contact with each other can be substantially maintained at a constant value during the rotation. In other words, when the first fixing portion 210 and the second fixing portion 120 are relatively rotated, the frictional force generated by them and the corresponding torque required to be rotated can be kept constant during the process.

In summary, the present invention is a pivot assembly and an electronic device using the same, which improves the friction between the wire and the pivot assembly and its shaft body, and is recessed by the surface of the shaft body. The groove is replaced by the design of the hollow structure. In the process, compared with the hollow structure along the axis of the shaft body, the technical difficulty of making the accommodating groove on the surface of the shaft body is relatively low, and the creation can also omit the lubricant, thereby reducing the production. Cost, in addition, is more convenient in terms of assembly.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make some changes and refinements without departing from the spirit and scope of the present invention.
