Example 1
In a first aspect, embodiment 1 provides a supporting device for a portable electronic device, including a supporting seat, a limiting seat and at least one set of link mechanisms, where a side link of each link mechanism is rotatably connected to the supporting seat and the limiting seat through a hinge shaft, and when the supporting seat rotates around the limiting seat within a range of 0 to 90 °, the supporting seat and the limiting seat provide a supporting platform for supporting the electronic device; wherein, at least one articulated shaft adopts a damping rotating shaft mechanism, which is used for keeping the supporting seat to stay in a range of 0-90 degrees when rotating around the limiting seat, and the connecting rod mechanism adopts a double-rocker mechanism.
The following is a detailed description: a portable electronic device supporting device comprises a supporting seat 10, a limiting seat 11, an upper cover 106, a bottom cover 117 and two groups of double-rocker mechanisms, wherein each group of double-rocker mechanisms comprises an upper frame 102, a lower frame 114, a front side link 14 and a rear side link 15. The two groups of double-rocker mechanisms are positioned at two sides of the supporting seat/the limiting seat. Specifically, the left and right sides of the supporting seat 10 are respectively fixedly connected with the upper frame 102 through screws 101, the two sides of the limiting seat 11 corresponding to the supporting seat are also respectively provided with a lower frame groove 111 for placing a lower frame 114, and the lower frame 114 is installed in the lower frame groove 111 and fixed through screws. The front side link 14 and the rear side link 15 each have an open elastic hole at both ends thereof, and the open elastic hole has a C shape. The upper frame 102 is provided with a front hole groove 103 and a rear hole groove 104 which are respectively used for installing the front side link 14 and the rear side link 15; a damping shaft (i.e., a damping rotating shaft) 16 is interference-fitted with the open elastic hole at one end of the front side link 14 and is installed in the front hole groove 103 of the upper frame 102, and correspondingly, the damping rotating shaft 16 is interference-fitted with the open elastic hole at one end of the rear side link 15 and is installed in the rear hole groove 104 of the upper frame 102. The lower frame 114 corresponding to the front and rear hole grooves is also correspondingly provided with a front groove 115 and a rear groove 116 for connecting the front and rear side links, the open elastic hole at the other end of the front side link 14 is in interference fit with the front groove 115 of the lower frame 114 through a damping shaft and is installed in the rear groove 116 of the lower frame 114, and correspondingly, the open elastic hole at the other end of the rear side link 15 is in interference fit with the rear groove 116 of the lower frame 114 through a damping shaft. In order to make the support seat integral smooth in the rotating process, the rear side link 15 of each group of double-rocker mechanism is connected into a whole through a connecting piece 151 so as to form a rear side link assembly with an H shape. (or for processing convenience, the H-shaped rear side link component can be integrally formed, and then the end parts at two sides are processed into open elastic holes); therefore, a communicating groove 112 communicating with the lower frame groove 111 is formed in the stopper base opposite to the link 151; the size of the lower frame groove 111 and the communicating groove 112 is equal to the size of the orthographic projection area of the rear connecting frame rod component in the shape of H.
As shown in fig. 1(a1), a protruding stopper 113 integrally connected with the supporting seat 11 extends upward at the front end of the supporting seat, and when the supporting seat rotates around the supporting seat within 0-90 °, the protruding stopper 113, the supporting seat and the supporting seat form a U-shaped groove with an open side view when the supporting seat is opened at any angle. 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.
The movement process of the supporting device of the present application is further described below:
when the supporting seat 10 and the upper cover thereon are placed horizontally, the point B of the front end of the upper cover is substantially flush with the point 113A of the protruding stop 113 of the limiting seat 11, and is located on the same plane, and the point B of the front end of the upper cover is located on the inner side of the rear of the point 113 "a" (as shown in fig. 1(a 12)). 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 limiting seat 21 is further provided with a support groove 212 for accommodating the support seat 20, when the support seat and the limiting seat are closed, the support seat is located in the support groove 212 of the limiting seat, and the limiting seat 21 is installed on the bottom cover 217 to form a base, so that a cavity structure is formed inside the base. 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. An upper cover 206 is also fastened to the support base 20.
When the support base is horizontally placed, the support base 20 and the upper cover 206 thereon are located in the support groove 212 of the limiting base, and the upper surface of the upper cover 206 is flush with the protruding stop 214.
When the supporting seat 20 starts to rotate around the limiting seat 21 (or the base), the end of the supporting seat 20 moves backward and downward relative to the convex stopper. Meanwhile, the front side link and the rear side link are connected by a damping shaft to generate damping torque to provide opening holding force for the support seat, and the opening and closing torque of the damping rotating shaft is shown in fig. 6 (b).

As can be seen from the above description and the attached drawings, the supporting device of this embodiment 2 is substantially the same as that of embodiment 1, and a side link is also used to connect the supporting seat and the limiting seat, so that the supporting seat rotates around the limiting seat through the movement of the side link. The movement process of the present embodiment 2 is also substantially the same as that of the embodiment 1, and the description thereof will not be repeated. The supporting device of this embodiment 2 is different from the supporting device of embodiment 1 in that in this embodiment 2, the upper and lower frames of embodiment 1 are respectively integrated with the supporting seat and the limiting seat, and the limiting seat/the supporting seat of this embodiment 2 are connected by independent side links. Of course, in a possible implementation, the rear side links can also be connected into a whole by the connecting members as shown in example 1.

The upper shaft of the rotating shaft of the damping rotating shaft mechanism is provided with a rotation stopping plane which is used for driving the locking cam and the rotation stopping gaskets A/B to rotate together, and the disc springs between the rotation stopping gaskets A/B also rotate together. The rotation stopping gasket A/B and the locking cam central hole are non-circular (two straight edges are matched with two planes of the main shaft and do not rotate), when the nut is screwed and fixed, the disc spring provides axial thrust for the locking cam, and the end face of the rotating shaft and the end face of the fixing plate generate friction force. The lower shaft of the rotating shaft of the damping rotating shaft mechanism is fixed in a connecting hole at one end of the front (rear) side link in an interference fit manner (at the moment, open elastic holes at two ends of the front (rear) side link can be set into closed connecting holes), the connecting hole at the other end of the front (rear) side link is rotatably connected with the supporting seat through the rotating shaft, a fixing plate of the damping rotating shaft mechanism is installed on the limiting seat, a person skilled in the art can properly deform the limiting seat and the supporting seat according to the damping rotating shaft mechanism, when the supporting seat rotates around the limiting seat, the rotating shaft rotates relative to the fixing plate, and the rotating shaft does not rotate relative to the front (rear) side link.

The locking cam surface and the friction end surface c of the fixed plate are both cam curved surfaces, and the bracket can be set to have a locking force when being closed at 10-0 degrees; the opening and closing torque curve diagram is shown in fig. 6(d), and it can be seen from the diagram that when the supporting seat is initially opened, about 10 degrees, the initial opening torque of the damping rotating shaft mechanism is larger than the opening torque of the damping rotating shaft mechanism at 30 degrees, so as to provide a certain resistance for the initial opening of the supporting seat. It can be seen from the figure that as the opening angle of the supporting seat increases, the opening torque force enters a stable state, and the supporting seat can be opened smoothly, and the opening and closing torque force curve thereof is shown in fig. 6 (d).
