When the mobile phone support is used specifically, electronic products such as a mobile phone and a tablet personal computer can be supported and leaned on the support seat, and the bottom of the mobile phone is propped against the protruding stop block of the U-shaped groove, so that a stable support is provided for the mobile phone. A bottom cover 117 is fastened to the bottom of the limiting seat 11 to form a base, and an upper cover 106 is fastened to the supporting seat 10. When the support base is horizontally placed on the base, the upper surface of the upper cover is substantially flush with the protruding stopper.
As shown in fig. 1(b11), the hinge shafts a, b, c and d of the front and rear side links of each set of double-rocker mechanism and the upper and lower frames can be arbitrarily set as one or more damping rotating shafts to form damping torque, and provide 0-90 degrees of opening and closing holding force of the supporting seat. During the opening process, as shown in fig. 1(b21) -fig. 1(b31), the shafts a, b, c and d do not rotate relative to the upper and lower frames, and the front and rear connecting rods are in interference fit with the shafts to generate damping torsion, and the damping torsion can also be provided by other ways, such as an additional axial disc spring and a friction plate or a radial holding manner.
As can be seen from fig. 1, in this embodiment 1, the upper and lower frames, the front side link and the rear side link form an integral four-bar linkage, wherein the front side link has an arc-shaped cross section, and the open elastic holes at the two ends of the front side link and the rear side link are connected with the damping shaft (i.e., the damping rotating shaft) in a matching manner to generate the damping torque. Therefore, when the upper frame on the left side and the right side of the supporting seat start to rotate around the lower frame, the left side and the right side of the supporting seat can be opened synchronously; therefore, when the supporting seat is opened, the supporting seat can integrally and smoothly rotate around the base (or the limiting seat). The opening and closing torque curve of the support seat rotating around the base is shown in fig. 6 (b). As shown in fig. 6(b), the outside diameter of the torsion curve shaft is not a complete circle and should be similar to a D-shape, so the C-shaped opening of the side link also needs to be similar to a D-shape on the inside diameter surface to match with the shaft). (the actual illustration shows that the torque curve corresponding to the opening direction of the side link is similar to that of fig. 6(e), i.e. the torque is light on and heavy off.)
As can be seen from fig. 6(b), the opening torque gradually increases when the supporting seat is opened at 0-20 °, and the opening torque is in a steady state when the supporting seat is opened at an enlarged opening angle.
In this application embodiment 1, adopt two rocker mechanism and damping pivot to connect between supporting seat and the spacing seat, the two rocker mechanism of this embodiment 1 has set up upper and lower frame, consequently when the supporting seat rotated around spacing seat, goes up the frame and just is equivalent to two rocker mechanism's "connecting rod".
In one embodiment, the connecting member 151 connecting the rear side link 15 may not be provided, and only each set of double-rocker mechanism is provided at two sides of the supporting seat and rotatably connected with the supporting seat and the limiting seat.
In one embodiment, the bump stopper may not be provided on the stopper seat, and may be replaced by the following manner: a V-shaped groove is formed in the limiting seat at the front end of the connecting position of the limiting seat and the supporting seat, when the supporting seat rotates around the limiting seat, the V-shaped groove and the supporting seat provide a supporting platform for supporting electronic equipment such as a mobile phone, the bottom of the mobile phone is supported in the V-shaped groove, and the back of the mobile phone leans on the supporting seat. And a support groove for placing the support seat is also formed on the limiting seat at the rear end (namely, the rear part of the connecting position), and when the support seat is in a horizontal state, the support seat is placed in the support groove.
In one embodiment, the damping rotation shaft is set to about 0-10 ° and the initial opening torque of the damping rotation shaft is greater than the opening torque of the damping rotation shaft at 30 ° to provide a certain resistance to the initial opening of the support seat, and the opening and closing torque is shown in fig. 6 (d). Therefore, when the supporting seat is closed, the damping rotating shaft has a closing locking force at 0 degree, so that the supporting seat can resist certain external acting force and cannot be opened easily.
In an implementation mode, the upper frame and the lower frame are not required to be arranged, and connecting grooves used for being connected with the front side link and the rear side link in a rotating mode are directly formed in the supporting seat and the limiting seat. And one end (which can be a front side link or a rear side link) of one side link of each group of double-rocker mechanisms is rotatably connected with the upper/lower rack through a semi-automatic rotating shaft mechanism, so that semi-automatic opening and closing torque is provided for the supporting seat. Other ends of the front and rear side links are not provided with open elastic holes, and only need to be rotationally connected with the upper and lower frames through a common rotating shaft. The structure of the semi-automatic spindle mechanism is the same as that described in embodiment 3.

At this time, the connecting member 151 between the rear link holders 15 is horizontally placed in the communicating groove 112 of the stopper base.
When the supporting seat starts to rotate around the limiting seat 11, the point B at the front end part of the upper cover moves backwards and downwards relative to the point A of the protruding stop block at the front end of the limiting seat. At the same time, the front side link 14 and the rear side link 15 rotate about their damping shafts, which do not rotate relative to the upper and lower frames, providing an opening holding force for the support base. When the supporting seat is opened at a certain angle and is kept still, the supporting seat, the protruding stop block at the front end of the limiting seat and the limiting seat form a U-shaped groove with the side surface looking open, and a stable supporting platform can be provided by horizontally or vertically placing the mobile phone or the tablet computer.
When the supporting seat rotates around the limiting seat (or the base), the supporting seat is connected with the limiting seat through the front and rear frame connecting rods, so that the length of the front and rear frame connecting rods also limits the rotating angle of the supporting seat. As shown in fig. 1(b11), the connecting rotation points of the upper frame 102 and the front and rear side link rods are respectively named as point a and point b, and the connecting rotation points of the lower frame 114 and the front and rear side link rods are respectively named as point c and point d, so that the sum of the lengths of ab and ac is smaller than the sum of the lengths of bd and cd in order to enable the supporting seat to rotate around the limiting seat within the range of 0-90 °.
In the embodiment, damping torque is arranged at any one or more positions of the hinging shafts at the points a, b, c and d, so that 0-90-degree closing retaining force is provided for the supporting seat. In the process of opening the supporting seat, shafts at points a, b, c and d do not rotate relative to the upper frame and the lower frame, the front connecting frame rod and the rear connecting frame rod are in interference fit with the shafts to generate damping torsion, and the damping torsion can be provided in other modes, such as an additional axial disc spring and a friction disc or a radial clamping mode.

The front end of the limiting seat 21 is integrally formed with a convex edge 213 extending upward and forward, and when the limiting seat 21 and the bottom cover 27 are fixed, the convex edge 213 abuts against the front end of the bottom cover to form a protruding stop 214.
