First, referring to fig. 1 and 2, the foldable stand of the present utility model comprises a sheet-like composite layer 10 and at least one bonding element; the sheet-like layer 10 is intended to be attached to a back plate 21 of a mobile device 20; the mobile device 20 is illustrated as a mobile phone; the back plate 21 is typically made of a magnetically attractable metal, but it is not excluded to make the back plate 21 of a non-magnetically attractable material such as plastic or nonferrous metal; at least one of the bonding elements may comprise a first bonding element 30 and a second bonding element 31.

With continued reference to fig. 3, the sheet-like composite layer 10 is disclosed as being formed by combining a seat body 11 for attaching to the back plate 21, a foldable inner body 12, and an outer body 13 for supporting the mobile device 20. Wherein:

the two ends of the seat body 11 are respectively a bonding end face 11a and a compound end face 11b. The attaching end face 11a may be made of a material having an adhesive capability, or the first adhesive member 30 may be embedded in the seat body 11, so that the attaching end face 11a of the seat body 11 has an anti-loosening capability of being firmly attached to the back plate 21. The first adhesion element 30 may be made of, for example, a magnetic material (such as a magnetic plate, a magnetic strip or a permanent magnet) capable of generating magnetic force lines, so that the first adhesion element 30 can be located in the adhesion end face 11a or embedded in the seat body 11 made of a non-magnetic material such as a rubber plate, a flannelette, rubber or leather, and the adhesion end face 11a generates magnetic force lines outwards, in which the back plate 21 is formed with a magnetically attractive material capable of receiving the magnetic force of the magnetic material, so that the adhesion end face 11a can be firmly attached to the back plate 21; the magnetic material may be made of magnetically permeable metal material.

In addition, the first adhesive element is an adhesive member having an adhesive or fastening function, the back plate is formed with an adhered object capable of receiving the adhesive fastener, the first adhesive element 30 may also be made of an adhesive member having an adhesive or fastening function (such as an adhesive tape, a velcro or a double sided adhesive), in which case the back plate 21 is formed with an adhered object capable of receiving the adhesive fastener (such as a base tape of an adhesive tape or a velcro or a surface capable of receiving double sided adhesive), so that the adhering end face 11a can be firmly adhered to the back plate 21.

The inner sheet 12 is cut to form at least two tongues capable of being lifted, including a first tongue 121 and a second tongue 122. The first tongue piece 121 is folded to form a first folded line portion 121a and a first bent portion 121b; the first tongue piece 121 is integrally connected to the inner sheet 12 via the first fold line portion 121a, the first tongue piece 121 is divided into a liftable first liftable portion 121c and a liftable first fixing portion 121d fixedly connected to the outer sheet 13 via the first curved portion 121b, and the first tongue piece 121 enables the first liftable portion 121c to be integrally connected to the inner sheet 12 via the first fold line portion 121 a. Correspondingly, the second tongue piece 122 is folded and formed with a second fold line portion 122a and a second bending portion 122b; the second tongue piece 122 is integrally connected with the inner sheet 12 through the second fold line portion 122a, the second tongue piece 122 is divided into a liftable second liftable portion 122c and a liftable second fixing portion 122d fixedly connected with the outer sheet 13 through the second bending portion 122b, and the second tongue piece 122 enables the second liftable portion 122c to be integrally connected with the inner sheet 12 through the second fold line portion 122 a. The second liftable portion 122c has a support length longer than that of the first liftable portion 121c (described later).

Furthermore, the inner sheet 12 is further folded by a folding line 125 to form a bonding surface 123 and a liftable surface 124, and a part of the surface of the bonding surface 123 is used for bonding to the composite end surface 11b of the seat sheet 11. The liftable surface 124 has a lap portion 124a formed thereon for providing adhesion of the second liftable portion 122 c.

The second attachment element 31 may be attached to or embedded in one of the second liftable portion 122c and the overlap portion 124a. Further, the second attachment element 31 may be made using the magnetic material or adhesive used for the first attachment element 30, with the difference that: when the second adhesive element 31 is made of a magnetic material, the magnetic material is required to be formed on the second liftable portion 122c or the bridging portion 124a, which is not loaded with the magnetic material. When the second adhesive element is a fastener with a bonding or fastening function, the second liftable portion 122c or the overlap portion 124a with the bonding element is removed, and the adhered object capable of receiving the bonding element must be formed.

Referring to fig. 4, a portion of the surface of the bonding surface 123 of the inner sheet 12 is bonded to the composite end surface 11b of the seat sheet 11, so that the inner sheet 12 and the seat sheet 11 can be combined into a whole; the first tongue piece 121 and the second tongue piece 122 of the inner sheet 12 are in a bending shape capable of being lifted; in particular, the inner sheet 12 can be fixed to the corresponding end surface of the outer sheet 123 by the first fixing portion 121d and the second fixing portion 122d, and then combined into a whole.

Next, please refer to fig. 5a, 5b to 5c. Wherein:

fig. 5a shows a side view of the sheet-like composite layer 10 attached to the back plate 21, showing the sheet-like composite layer 10 being thinned, space-saving and hand-held by a user before being unfolded.

Fig. 5b shows that the user can lightly peel the outer sheet 13, so that the outer sheet 13 can use the first liftable portion 121c on the first tongue 121 and the second liftable portion 122c on the second tongue 122 of the inner sheet 12 as double swing arms, and further gradually unfold the outer sheet 13, wherein the liftable portion 124 is gradually lifted, and the liftable angle of the second liftable portion 122c connected to the second tongue 122 of the liftable portion 124 can be increased.

Fig. 5c shows that the second liftable portion 122c of the second tongue 122 is lifted to be capable of adhering to the lap portion 124a of the liftable surface 124 of the inner sheet 12, and the second liftable portion 122c and the lap portion 124a are adhered to each other by the second adhering element 31 to generate anti-loosening effect, and the first liftable portion 121c and the second liftable portion 122c are located between the seat sheet 11 and the outer sheet 13 to play a role of a supporting beam, and one end portion of the outer sheet 13 can apply a pushing force F to abut against a part of the surface of the adhering surface 123. In this state, since the support length H1 of the first liftable portion 121c and the support length H2 of the second liftable portion 122c are not equal; more precisely, the supporting length H2 of the second liftable portion 122c is greater than the supporting length H1 of the first liftable portion 121c, and after the second liftable portion 122c and the bridging portion 124a are firmly attached to each other, the supporting length H2 of the second liftable portion 122c should be interpreted as including the lifting length of the liftable surface 124, so that the unfolded support frame can present a firm support structure with triangular area.

With reference to fig. 6, the support frame with triangular area after being unfolded is placed on a table top 40, the end portion of the outer sheet 13 can apply the pushing force F to abut against the surface of the abutting surface 123, so as to disperse the gravity of the mobile device 20 when being supported on the table top by virtue of the inner sheet 12 and the outer sheet 13, so that the support frame of the present utility model can stably support the mobile device 20 on the table top 40.

When the user wants to fold the support frame, the user only needs to remove the second liftable portion 122c and the overlap portion 124a, which are firmly attached to each other, so as to separate them from each other, and then can easily fold the second liftable portion 122c on the second tongue piece 122, so that the inner sheet 12 and the outer sheet 13 can be restored to the state of fig. 5a, that is, the inner sheet 12, the outer sheet 13 and the seat sheet 11 are again combined into the sheet-like multi-layer 10, so that the user can hold the mobile device 20 attached with the sheet-like multi-layer 10.

Next, referring to fig. 7, another embodiment of the present utility model is disclosed, which is different from the above embodiment in that: the carrier body 11 in the embodiment shown in fig. 1 to 6 is omitted, i.e. the inner body 12 is made to have the same function as the carrier body 11 can be attached to the back plate 21 of the mobile device 20. Further, the bonding surface 123 of the inner sheet 12 replaces the bonding end surface 11a provided by the original seat sheet 11, so that the bonding surface 123 is made of a material with bonding capability, or the first bonding element 30a is embedded in the bonding surface 123, so that the inner sheet 12 can be firmly attached to the back plate 21 by virtue of the bonding surface 123. Except for this, the remainder of the implementation shown in fig. 7 is substantially the same as the implementation shown in fig. 1-6.

According to the above embodiments, the sheet-like composite layer 10 is formed by combining the seat body 11, the inner body 12 and the outer body 13, or by combining only the inner body 12 and the outer body 13, and the outline of each sheet can be made into, for example, a quadrangular sheet as shown in the above figures, or other identical outline (such as a circle, a trapezoid, or an ellipse), so as to facilitate the user to hold the mobile device 20 to which the sheet-like composite layer 10 is attached.

The above description is illustrative of the utility model and is not to be construed as limiting, and it will be understood by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
