Furthermore, the expansion and contraction joint 1221 extends along the axial direction of the shaft hole 113, and when the shaft body 122 rotates in the shaft hole 113, in order to maintain a stable frictional force, the position of the thickened layer 1222 in the axial direction will be changed. Located in the middle of the axial position of the expansion and contraction joint 1221, and the axial position of the thickened layer 1222 is also located in the middle of the axial position of the shaft hole 113, that is, the thickened layer 1222 The two opposite sides in the axial direction are consistent with the distance between the two opposite sides of the shaft hole 113 .

Please refer to FIGS. 6A to 6C . FIGS. 6A to 6C are schematic diagrams illustrating the operation of the stand device 10 according to an embodiment of the present invention. When the first bracket member 11 and the second bracket member 12 of the bracket device 10 are deployed relative to each other (as shown in FIG. 1 ), the relative positions of the shaft body 122 and the shaft hole 113 in the pivot assembly 100 will be as follows: As shown in FIG. 6A (this relative position is defined as 0 degree position below), in this case, the thickened layer 1222 on the arc wall 1223 of the outer contour of the shaft body 122 will interfere with the first position of the inner contour of the shaft hole 113. The arc portion 1131, while the plane wall 1224 of the outer contour of the shaft body 122 is in conflict with the straight portion 1132 of the inner contour of the shaft hole 113, in other words, the outer contour of the shaft body 122 and the inner contour of the shaft hole 113 are just right The state of the match.

When the first bracket part 11 and the second bracket part 12 of the bracket device 10 pivot relative to each other by 45 degrees, the relative positions of the shaft body 122 and the shaft hole 113 in the pivot assembly 100 will be as shown in FIG. 6B (hereinafter referred to as This relative position is defined as the 45 degree position), in this case, the thickened layer 1222 on the arc wall 1223 of the outer contour of the shaft body 122 will interfere with the linear part 1132 of the inner contour of the shaft hole 113, because the two straight lines Partial spacing will be smaller than the spacing between the two thickened layers 1222 of the shaft body 122, so the shaft body 122 will be compressed by the two linear parts of the shaft hole 113, so that the distance between the expansion and contraction joints 1221 will become smaller, and the shaft body 122 will be Due to the compression of the expansion and contraction joints 1221, an elastic restoring force is generated in the radial direction. This elastic restoring force will increase the stress applied by the two thickened layers 1222 to the inner wall of the shaft hole 113. Correspondingly, the friction between the shaft body 122 and the shaft hole 113 force will increase. That is to say, at the 0 degree position, the frictional force between the shaft body 122 and the shaft hole 113 is relatively small. A large force can make the shaft body 122 and the shaft hole 113 rotate relatively to overcome the relatively large frictional force between the shaft body 122 and the shaft hole 113 .

When the first bracket part 11 and the second bracket part 12 of the bracket device 10 pivot relative to each other by 90 degrees, the first bracket part 11 and the second bracket part 12 can form the aforementioned inverted V-shaped support structure, as shown in Figure 2 , and at this time the relative position of the shaft body 122 of the pivot assembly 100 and the shaft hole 113 will be shown in FIG. The thickened layer 1222 on the arc wall 1223 will interfere with the second arc portion 1133 of the inner contour of the shaft hole 113, because the distance between the two second arc portions 1133 will be greater than the distance between the two straight portions 1132, therefore, relatively At a position of 45 degrees, the distance between the expansion and contraction joints 1221 of the shaft body 122 will increase and the elastic recovery force will decrease accordingly. Moreover, when the two thickened layers 1222 fall into the two second arc portions 1133, a positioning effect will be produced.

By analogy, when the first support member 11 and the second support member 12 pivot to 180 degrees relative to each other and overlap each other (hereinafter this relative position is defined as a 180 degree position), the positioning effect will also be produced. The relative positions of the shaft body 122 and the shaft hole 113 in the hour pivot assembly 100 can be referred to as shown in FIG. 6A , where the difference is mainly that the shaft hole 113 is rotated 180 degrees relative to the shaft body 122 .

From the above, it can be seen that at the positions of 0°, 90° and 180°, the first support member 11 and the second support member 12 will have a positioning effect, that is, it is necessary to apply a relatively large force to make the first support member 12 in these three positions. The bracket part 11 and the second bracket part 12 are further rotated relative to each other, because there are positioning effects at these three positions, so when the shaft body 122 and the shaft hole 113 rotate relative to each other between 0 to 90 degrees and 90 degrees to 180 degrees, there will be Larger friction force, which means that the first bracket 11 and the second bracket 12 can be in three states: unfolded state (0 degree position), support state (90 degree position) and stacked state (180 degree position) It has a good maintenance or support effect. Compared with the pivot assembly used to produce the positioning effect in the prior art, the pivot assembly 100 of the present embodiment has a simpler structure, which can improve the yield and reduce the cost.

The difference between the pivot assembly 100' and the pivot assembly 100 of FIGS. 1 to 6C is mainly The shaft hole 113 of the first pivot member 110 will be described in detail later, and the same or similar components and connections of the pivot assemblies 100 and 100 ′ will not be described again.

Please refer to FIG. 8 , which is a schematic diagram of the first pivot member 110 according to another embodiment of the present invention. The pivot accommodating part 112 of the first pivot member 110 of the pivot assembly 100' is a single-pack structure, and its ring wall 114 includes a fixed end 1141 and a free end 1142, and the fixed end 1141 and the free end 1142 are along the shaft hole 113. Axial extension. The first fixing portion 111 is fixedly connected to the fixing end 1141 , and the free end 1142 is separated from the fixing end 1141 by a distance to define a spacer 1143 . Since the free end 1142 and the fixed end 1141 have the relationship of the interval 1143, the shaft hole 113 has a certain degree of elasticity in the radial direction (that is, the shaft hole 113 can be expanded within the degree of elasticity to match the rotation of the shaft body 122). The function provided by the spacer 1143 in the cooperation between the shaft body 122 and the shaft hole 113 is similar to the expansion and contraction joint 1221 of the pivot assembly 100 (that is, the expansion and contraction joint 1221 can shrink within an elastic degree to match the rotation of the shaft body 122 ).

The ring wall 114 includes a portion of a thin wall 1144 and a portion of a thick wall 1145 , and the portion of the thin wall 1144 is a portion that is thinned on the inner wall of the shaft hole 113 . Due to the existence of the thin wall 1144, the two opposite sides of the ring wall 114 in the first direction d1 have a thin wall 1144 and a thick wall 1145 on the other side, that is to say, the ring wall 114 is not equal in the first direction d1. thick, and the two opposite sides of the ring wall 114 in the second direction d2 are both thick walls 1145 . Correspondingly, the first diameter b1 of the inner contour of the shaft hole 113 in the first direction d1 is larger than the second diameter b2 of the inner contour of the shaft hole 113 in the second direction d2, so the shaft hole 113 also forms a non-circular section on the vertical axis. The inner contour of the shape. In this embodiment, there are two parts of the thin wall 1144 , the two thin walls 1144 are arranged along the axial direction, and there is an intermediate region 1146 between the two thin walls 1144 , the thickness of the intermediate region 1146 is the same as that of the thick wall 1145 .

The shaft body 122 of the pivot assembly 100 and 100' is similar, and both of them have an arc wall 1223 and a plane wall 1224, so as to cooperate with the shaft hole 113. That is to say, when the shaft body 122 and the shaft hole 113 of the pivot assembly 100' are at the positions of 0 degrees, 90 degrees and 180 degrees, the positioning effect will also be produced, and the relative rotation between 0 to 90 degrees and 90 degrees to 180 degrees greater frictional force will be generated, so that the first bracket part 11 and the second bracket part 12 can be in the unfolded state (0 degree position), support state (90 degree position) and superimposed state (180 degree position) and so on. It has a good maintenance or support effect in the state. The principle can refer to FIG. 6A to FIG. 6C and related descriptions, and will not be repeated here.
