[0035] Reference Figure 1-8 The figure shows a preferred embodiment of the present invention.

[0036] A foldable mobile phone case comprises an upper shell 10, a lower shell 20 and a connecting layer 30. The upper shell 10 has an upper mounting surface, the lower shell 20 has a lower mounting surface, and the connecting layer 30 is stretched or contracted when subjected to force. When the mobile phone case is unfolded, the upper mounting surface and the lower mounting surface are horizontally arranged correspondingly; an upper mounting groove concave downwardly is formed on the upper mounting surface, and a lower mounting groove concave downwardly is formed on the lower mounting surface, and the two ends of the connecting layer 30 are respectively flattened and fixed with the upper mounting groove and the lower mounting groove.

[0037] The above-mentioned foldable mobile phone case is unfolded when in use. At this time, the upper mounting surface and the lower mounting surface are arranged horizontally and correspondingly to form a plane, so that the mobile phone can be placed. At the same time, the tensile force on the connecting layer 30 is small, and the connecting layer 30 makes the upper shell 10 and the lower shell 20 relatively fixed. Under the action of the upper shell 10 and the lower shell 20, the mobile phone is protected; when not in use, the mobile phone case is folded, the upper shell 10 and the lower shell 20 are overlapped, and the connecting layer 30 is stretched under the tensile force, so that the upper shell 10 and the lower shell 20 are relatively fixed, which is convenient for carrying the mobile phone; in addition, the upper mounting groove and the lower mounting groove are arranged to avoid exposure of the connecting layer 30, and when the mobile phone case is folded, the tensile force applied to the connecting layer 30 is effectively reduced, thereby increasing the service life of the connecting layer 30; in this way, the foldable mobile phone can be protected whether in use or storage.

[0038] The foldable mobile phone case comprises a plurality of shuttle bars 40 , and the shuttle bars 40 are arranged in a long strip shape, so that the shuttle bars 40 can shuttle along the length direction.

[0039] Along the width direction, the shuttle bars 40 are arranged in sequence to ensure that the shuttle bars 40 effectively cover the exposed area of ​​the connection layer 30 , thereby effectively preventing the connection layer 30 from being exposed and protecting the connection layer 30 .

[0040] Furthermore, connecting blocks are provided between adjacent shuttle bars 40, and the two ends of the connecting blocks are respectively connected to fix adjacent shuttle bars 40, so that each shuttle bar 40 can move synchronously and form a whole, thereby reducing the lateral deviation of the shuttle bar 40 when moving.

[0041] One end of the shuttle bar 40 is fixedly connected to the lower shell 20, and the upper shell 10 has a shuttle hole, and the other end of the shuttle bar 40 passes through the shuttle hole. When the mobile phone case is gradually unfolded, the other end of the shuttle bar 40 gradually shuttles away from the upper shell 10, and the connecting layer 30 and each shuttle bar 40 are arranged in correspondence with each other up and down; when the mobile phone case is folded, the other end of the shuttle bar 40 shuttles toward the upper shell 10 and does not leave the shuttle hole; in this way, when the mobile phone case is folded or unfolded, the shuttle bar 40 shuttles to protect the connecting layer 30. At the same time, if the mobile phone case falls, each shuttle bar 40 plays a buffering and shock-absorbing role, thereby enhancing the protection effect of the folded mobile phone.

[0042] The upper shell 10 is thinned to form an upper thinned area, and the lower shell 20 is thinned to form a lower thinned area. One end of the shuttle bar 40 is docked and fixed to the lower thinned area. The upper thinned area is provided with a shuttle member, and the shuttle member forms a shuttle hole. The other end of the shuttle bar 40 passes through the shuttle member; thereby reducing the thickness of the mobile phone case and facilitating the setting of the shuttle member and the shuttle bar 40.

[0043] The top surface of the other end of the shuttle bar 40 is arranged in an arc transition, which reduces the mutual wear between the shuttle bar 40 and the shuttle member when the shuttle bar 40 moves in a shuttle manner, thereby increasing the service life.

[0044] Furthermore, along the direction away from one end of the shuttle bar 40, the thickness of the other end of the shuttle bar 40 gradually decreases, and the bottom of the other end of the shuttle bar 40 is attached to the thinned area; this facilitates the movement of the shuttle bar 40, and at the same time, facilitates the other end of the shuttle bar 40 to move in contact with the upper thinned area, thereby reducing the shaking of the shuttle bar 40 during movement and improving the movement stability of the shuttle bar 40.

[0045] Another embodiment of the shuttle bar 40 arrangement:

[0046] One end of the shuttle bar 40 is fixedly connected to the upper shell 10, and the lower shell 20 has a shuttle hole, and the other end of the shuttle bar 40 passes through the shuttle hole; when the mobile phone case is gradually unfolded, the other end of the shuttle bar 40 gradually shuttles in the direction toward the upper shell 10, and the connecting layer 30 and each shuttle bar 40 are arranged in correspondence with each other up and down; when the mobile phone case is folded, the other end of the shuttle bar 40 shuttles in the direction away from the upper shell 10 and does not leave the shuttle hole; in this way, when the mobile phone case is folded or unfolded, the shuttle bar 40 shuttles to protect the connecting layer 30. At the same time, if the mobile phone case falls, each shuttle bar 40 plays a buffering and shock-absorbing role, thereby enhancing the protection effect of the folded mobile phone.

[0047] The lower thinning area is provided with a shuttle member, the shuttle member forms a shuttle hole, and the other end of the shuttle bar 40 passes through the shuttle member.

[0049] The shielding cover includes a plurality of shield pieces, and the shield pieces are arranged end to end in sequence; when the mobile phone case is gradually unfolded, the shield pieces are gradually overlapped and contracted, and when the mobile phone case is gradually folded, the shield pieces are gradually unfolded and arranged in a wave shape; through the unfolding and contraction of the shield pieces, the connecting layer 30 is effectively shielded, and at the same time, the upper shell 10 and the lower shell 20 are arranged in a relatively fixed manner.

[0050] The connecting layer 30 has an outer end surface facing the shielding cover, and a buffer strip is provided on the outer end surface of the connecting layer 30. The buffer strip is extended along the length direction, and the bottom of the buffer strip is fixed to the outer end surface of the connecting layer 30; when the mobile phone case is folded, the top of the buffer strip contacts the shielding cover; under the action of the buffer strip, when the mobile phone case falls, the shielding cover plays a preliminary shock-absorbing role, and the buffer strip performs shock-absorbing again, thereby effectively enhancing the shock-absorbing effect.

[0051] One end of the connecting layer 30 forms an upper contact surface, and when one end of the connecting layer 30 is laid flat and fixed on the upper mounting groove, the upper contact surface is flush with the upper mounting surface; the other end of the connecting layer 30 forms a lower contact surface, and when one end of the connecting layer 30 is laid flat and fixed on the lower mounting groove, the lower contact surface is flush with the lower mounting surface; in this way, when the mobile phone is placed in the mobile phone case, the upper contact surface and the upper mounting surface as well as the lower contact surface and the lower mounting surface respectively contact the back of the mobile phone to form a plane, thereby protecting the back of the mobile phone, achieving synchronous contact with the back of the mobile phone, and enhancing the placement stability of the mobile phone.

[0052] The upper shell 10 and the lower shell 20 are combined to form a placement cavity, which is used to place a mobile phone; the upper contact surface is formed with a plurality of upper contact bars, which are arranged along the length, and each upper contact bar is arranged in sequence and spaced along the width direction, and the top of the upper contact bar is arranged flush with the upper mounting surface; the lower contact surface is formed with a plurality of lower contact bars, which are arranged along the length, and each lower contact bar is arranged in sequence and spaced along the width direction, and the top of the lower contact bar is arranged flush with the lower mounting surface; when the mobile phone is placed in the placement cavity, the bottom surface of the mobile phone contacts the top of each upper contact bar and the top of each lower contact bar.

[0053] In this way, under the action of each upper and lower contact strip, the overall height of the space in which the mobile phone is placed in the placement cavity is increased, which is convenient for the heat dissipation of the mobile phone. At the same time, when the mobile phone falls, the bottom is protected and shock-absorbing.

[0054] The lower shell 20 includes a lower bottom plate 28 having a lower mounting surface. The lower bottom plate 28 is formed with a lifting platform 27, and the lifting platform 27 is located below the lower mounting surface.
