First embodiment

A supporting device 100 according to a first embodiment of the present invention will be described in detail with reference to fig. 1 to 4.

As shown in fig. 1 to 3, the supporting device 100 mainly includes a back plate 110 and a supporting member 120 connected to the back plate 110, wherein the back plate 110 is used for connecting to a mobile terminal. As shown in fig. 3, one side of the back plate 110 is connected to the mobile terminal 10, and the support member 120 is connected to a side of the back plate 110 facing away from the mobile terminal 10. The support member 120 can be switched between a stored state (fig. 1) laid flat on the back plate 110 and a support state (fig. 2 to 3) expanded into a solid shape, and the support member 120 in the support state can support the mobile terminal 10 on a table at an angle with respect to a horizontal plane.

The back plate 110 may have a magnet built therein, or a magnet may be disposed on one side surface of the back plate 110, so that the one side surface of the back plate 110 may be attracted to the mobile terminal 10 having a magnetic coil built therein. In another embodiment, not shown, a side of the back plate is provided with a backing glue, such that the back plate can be attached to the mobile terminal by the backing glue. In another embodiment, not shown, the peripheral edge of the back plate may be provided with a bent snap-in portion, which may be snapped into the mobile terminal.

In the present embodiment, the back plate 110 is configured substantially as a rectangular plate. The back panel 110 preferably has an overall size smaller than that of the mobile terminal 10 so that the supporting device 100 in the stored state is not easily visible from the front of the mobile terminal 10 when the mobile terminal 10 is placed on a desktop at the front. It will be understood by those skilled in the art that the shape of the back plate 110 is not limited to the present embodiment, and the back plate 110 may be configured as a square, a polygon, or any other suitable shape plate as required.

With continued reference to fig. 1-3, the support member 120 basically includes a first connection plate 121, a second connection plate 122, a third connection plate 123 and a fourth connection plate 124. The first connecting plate 121, the second connecting plate 122, the third connecting plate 123, and the fourth connecting plate 124 are made of a rigid material, and are each configured in a flat plate shape. For example, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 may be made of a metal material.

The first connecting plate 121 is invertably connected to the back plate 110, the second connecting plate 122 is invertably connected to the first connecting plate 121, the third connecting plate 123 is invertably connected to the second connecting plate 122, the fourth connecting plate 124 is invertably connected to the third connecting plate 123, and the fourth connecting plate 124 is connected to the back plate 110. That is, the first connecting plate 121 may be turned with respect to the back plate 110, the second connecting plate 122 may be turned with respect to the first connecting plate 121, the third connecting plate 123 may be turned with respect to the second connecting plate 122, and the fourth connecting plate 124 may be turned with respect to the third connecting plate 123. In the present embodiment, the fourth connecting plate 124 is movably connected to the backplate 110 with respect to the backplate 110.

Specifically, one side of the first connecting plate 121 is connected to one side of the back plate 110 in a reversible manner, for example, connected to the long side of the back plate 110 in a reversible manner. The length of the side of the first connecting plate 121 may be equal to or slightly less than the length of the side of the back plate 110. One side of the second connecting plate 122 is pivotally connected to the other side of the first connecting plate 121, for example, pivotally connected to a side of the first connecting plate 121 away from the back plate 110. One side of the third connecting plate 123 is turnably connected to the other side of the second connecting plate 122. One side of the fourth connecting plate 124 is connected to the other side of the third connecting plate 123 in a reversible manner.

The first connecting plate 121 is configured substantially as a trapezoidal shaped plate, the second connecting plate 122 and the third connecting plate 123 are each configured substantially as a parallelogram shaped plate, and the fourth connecting plate 124 may be a plate of any suitable shape. It may be understood by those skilled in the art that the structures of the first, second, and third connection plates 121, 122, and 123 are not limited to the present embodiment. The first, second and third connecting plates 121, 122, 123 may also be any other suitably shaped structure, as desired.

In the present embodiment, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 are separately provided, so that it is convenient to process the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124, and to achieve reversible connection between adjacent two of the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124. In another embodiment, not shown, at least two of the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 are integrally provided. For example, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 are integrally formed, so that the number of parts can be reduced, and the production cost can be reduced.

As shown in fig. 1, when the supporting member 120 is in the storage state, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 are located on the same plane parallel to the backplate 110, and the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 are all laid on the backplate 110, so that the supporting device 100 is compact and has a thin overall thickness, so as to achieve a certain degree of "stealth" for storage. As shown in fig. 2 and 3, when the support member 120 is in the support state, neither the first connecting plate 121 nor the third connecting plate 123 is parallel to the back plate 110, and the second connecting plate 122 is spaced apart from the back plate 110 by a predetermined distance, so that the support member 120 is unfolded into a solid shape, thereby enabling the mobile terminal 10 to be supported on a table top at an angle with respect to the table top.

Since the third connecting plate 123 is configured as a parallelogram plate, and opposite ends of the third connecting plate 123 are reversibly connected to the second connecting plate 122 and the fourth connecting plate 124, respectively, such that when the support member 120 is in the supporting state, both the second connecting plate 122 and the fourth connecting plate 124 are parallel to the backplate 110, and the fourth connecting plate 124 is laid flat on the backplate 110. In the present embodiment, the first connecting plate 121 and the third connecting plate 123 together determine a supporting angle of the supporting member 120, that is, an angle at which the supporting device 100 supports the mobile terminal 10 on a desktop. For example, the supporting angle of the supporting member 120 may be changed by changing the height of the third connecting plate 123.

As shown in fig. 1 to 4, the back plate 110 is provided with guide holes 126. The guide hole 126 is disposed at a side of the back plate 110 away from the first connection plate 121 and is configured as an arc-shaped hole. The support member 120 further includes a mount 125 (see fig. 4) connected to the fourth connection plate 124, and the mount 125 is movably disposed in the guide hole 126 along a length direction of the guide hole 126 so that the fourth connection plate 124 can slide along the back plate 110, thereby enabling the support member 120 to be switched between the storage state and the support state. That is, the fourth connecting plate 124 is always parallel to the back plate 110 and is tiled on the back plate 110. Therefore, when the supporting member 120 needs to be switched from the storage state to the supporting state, only the fourth connecting plate 124 needs to be pushed horizontally along the back plate 110, so that the mounting piece 125 slides along the guide hole 126 from one end of the guide hole 126 to the other end, and the operation is simple and convenient for the user.

As shown in fig. 1, when the support member 120 is in the storage state, the mounting part 125 is located at one end of the guide hole 126, that is, at one end of the guide hole 126 away from the second connection plate 122. As shown in fig. 2 and 3, when the support member 120 is in the support state, the mount 125 has moved along the guide hole 126 to the other end of the guide hole 126, i.e., to the end of the guide hole 126 near the second connection plate 122. Since the mount 125 moves along the guide hole 126 from the end of the guide hole 126 remote from the second link plate 122 to the end close to the second link plate 122, the third link plate 123 is turned relative to the fourth link plate 124, and the second link plate 122 and the first link plate 121 are turned as the third link plate 123 is turned, so that the support member 120 is switched from the storage state to the support state.

As shown in fig. 4, the mounting member 125 includes an extension 128 connected to the fourth web 124 and a projection 129 projecting radially outward from the extension 128. The extension 128 is substantially cylindrical in shape and the projection 129 is substantially annular plate-shaped. The side of the back plate 110 facing away from the second connecting plate 122 is provided with a groove 127, and the shape of the groove 127 corresponds to the shape of the guide hole 126. The guide hole 126 extends through the groove 127, and the extension 128 extends through the guide hole 126. The protrusion 129 is disposed in the groove 127 and does not protrude from the outer surface of the back plate 110. The mounting member 125 does not additionally increase the overall thickness of the support device 100 and prevents friction between the protrusion 129 and the mobile terminal 10 when the mounting member 125 slides along the guide hole 126.

The mounting member 125 and the fourth connecting plate 124 may be separately or integrally disposed, so as to optimize the structure of the mounting member 125 and the fourth connecting plate 124 according to actual needs and reduce production cost.

As shown in fig. 2, when the supporting member 120 is in the supporting state, the included angle a between the third connecting plate 123 and the fourth connecting plate 124 satisfies: a is more than or equal to 60 degrees and less than or equal to 90 degrees. When the supporting device 100 is placed on a table top, the first connecting plate 121 is flatly placed on the table top, and the gravity of the mobile terminal 10 acts on the supporting member 120, so that the third connecting plate 123 applies a force to the mounting part 125 via the fourth connecting plate 124 toward the second connecting plate 122, limited by the size and shape of the guiding hole 126, and the mounting part 125 cannot continuously slide along the guiding hole 126, thereby keeping the supporting member 120 in a supporting state more firmly. It will be understood by those skilled in the art that the included angle a between the third connecting plate 123 and the fourth connecting plate 124 in the supporting state is not limited to the above range, and a may be less than 60 ° or greater than 90 ° as required. For example, a may be 50 °, 55 °, 95 °, or 100 °.

As shown in fig. 1 and 2, the first magnetic portion 131 is disposed at a position of the back plate 110 corresponding to the second connecting plate 122, such that when the supporting member 120 is in the storage state, the second connecting plate 122 is magnetically attracted to the first magnetic portion 131, and therefore the second connecting plate 122 can be tightly attached to the back plate to prevent the second connecting plate 122 from tilting. Specifically, the first magnetic portion 131 may be a magnet, the second connecting plate 122 may be a magnet capable of magnetically attracting the first magnetic portion 131, or a magnet capable of magnetically attracting the first magnetic portion 131 is disposed on the second connecting plate 122, or the second connecting plate 122 is made of iron, so that the second connecting plate 122 is capable of magnetically attracting the first magnetic portion 131.

The support member 120 further includes a connector (not shown) connected to the back plate 110. In the present embodiment, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123, and the fourth connecting plate 124 are provided separately from the connecting member. The first, second, third and fourth connection plates 121, 122, 123 and 124 are connected to the connection members, respectively, and are disposed spaced apart from each other. In particular, the connecting element is made of a flexible material, for example, it may be made of cloth, leather material (dermis or artificial skin).

In the present embodiment, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123 and the fourth connecting plate 124 are attached to the connecting member. Specifically, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123, and the fourth connecting plate 124 are connected to the connecting members via glue. For example, the first connecting plate 121, the second connecting plate 122, the third connecting plate 123, and the fourth connecting plate 124 are bonded to the connecting members via liquid glue or solid glue, or the first connecting plate 121, the second connecting plate 122, the third connecting plate 123, and the fourth connecting plate 124 are thermally pressed to the connecting members via hot melt glue.

Thus, the connectors may be bent from the gap between the first connecting plate 121 and the back plate 110, the gap between the second connecting plate 122 and the first connecting plate 121, the gap between the third connecting plate 123 and the second connecting plate 122, and the gap between the fourth connecting plate 124 and the third connecting plate 123, so as to realize that the first connecting plate 121 is reversibly connected to the back plate 110, the second connecting plate 122 is reversibly connected to the first connecting plate 121, the third connecting plate 123 is reversibly connected to the second connecting plate 122, and the fourth connecting plate 124 is reversibly connected to the third connecting plate 123, thereby realizing that the support member 120 is switched between the storage state and the support state.

Preferably, the gap between the first connection plate 121 and the back plate 110 is 0.5mm to 3mm, the gap between the second connection plate 122 and the first connection plate 121 is 0.5mm to 3mm, the gap between the third connection plate 123 and the second connection plate 122 is 0.5mm to 3mm, and the gap between the fourth connection plate 124 and the third connection plate 123 is 0.5mm to 3 mm. Further preferably, the gap between the first connecting plate 121 and the back plate 110, the gap between the second connecting plate 122 and the first connecting plate 121, the gap between the third connecting plate 123 and the second connecting plate 122, and the gap between the fourth connecting plate 124 and the third connecting plate 123 are all equal, which not only facilitates the manufacturing, but also makes the appearance of the supporting device 100 more beautiful. It will be understood by those skilled in the art that the gap between the first connection plate 121 and the back plate 110, the gap between the second connection plate 122 and the first connection plate 121, the gap between the third connection plate 123 and the second connection plate 122, and the gap between the fourth connection plate 124 and the third connection plate 123 are not limited to the above ranges.

In one embodiment, not shown, the connector is integrally provided with at least one of the first, second, third and fourth connector plates. For example, the connecting member may be integrally formed with the first connecting plate, the second connecting plate, the third connecting plate, and the fourth connecting plate, so that the number of parts can be reduced, and the production cost can be reduced. In addition, the first connecting plate 121 can be connected to the back plate 110 in an invertible manner, the second connecting plate 122 can be connected to the first connecting plate 121 in an invertible manner, the third connecting plate 123 can be connected to the second connecting plate 122 in an invertible manner, and the fourth connecting plate 124 can be connected to the third connecting plate 123 in an invertible manner.

The back plate 210 is also provided with a first magnetic part 231 at a position corresponding to the second connecting plate 222, and when the supporting member 220 is in the storage state, the second connecting plate 222 is also magnetically attracted to the first magnetic part 231.
