When in use, the first inner shell 110 and the second inner shell 120 are unfolded, and the first outer shell 210 and the second outer shell 220 are also unfolded. At this time, the tensile force on the connecting strip 300 is small, and the inner shell 100 and the outer shell 200 are buckled to double protect the 3C product and improve the shock absorption and anti-fall effect; when not in use, the first inner shell 110 and the second inner shell 120 are folded. , the first shell 210 and the second shell 220 are also folded. At this time, the connecting strip 300 is stretched under the tensile force. In this way, the 3C product in the storage state is protected by the cooperation of the inner shell 100, the outer shell 200 and the connecting strip 300. At the same time, the inner shell 100 and the outer shell 200 provide double protection to improve the shock absorption and anti-fall effects. In this way, the double-shell foldable 3C product case can protect the 3C product whether it is in use or in storage, and improve the shock absorption and anti-fall effects.

[0039] The inner shell 100 and the connecting strip 300 are arranged in a mortise and tenon connection.

[0040] The outer shell 200 and the connecting strip 300 are arranged in a mortise and tenon connection.

[0041] When the first inner shell 110 and the second inner shell 120 are folded, they can be folded outwards or inwards.

[0042] When the first housing 210 and the second housing 220 are folded, they can be folded outwards or inwards.

[0043] The folding direction of the first inner shell 110 and the second inner shell 120 is consistent with the folding direction of the first outer shell 210 and the second outer shell 220 .

[0044] Another embodiment: the inner shell 100 and the outer shell 200 are snap-fitted, the first inner shell 110 and the second inner shell 120 are integrally arranged, and the first outer shell 210 and the second outer shell 220 are integrally arranged; that is, the inner shell 100 and the outer shell 200 provide double protection to achieve shock absorption and anti-fall effects.

[0045] That is to say, the double-shell 3C product shell can be suitable for foldable applications as well as non-foldable applications.

[0046] The first outer shell 210 includes a first outer top frame 211, and the first outer top frame 211 has a first top installation groove. The second outer shell 220 includes a second outer top frame 221, and the second outer top frame 221 has a second top installation groove. The connecting bar 300 includes an upper telescopic bar 310 that is stretched or contracted under force. One end of the upper telescopic bar 310 is flatly fixed to the first top installation groove, and the other end of the upper telescopic bar 310 is flatly fixed to the second top installation groove; the first inner shell 110 includes a first inner top frame 111, and the second inner shell 120 includes a second inner top frame 121. The first outer top frame 211 and the first inner top frame 111 clamp and fix one end of the upper telescopic bar 310, and the second outer top frame 221 and the second inner top frame 121 clamp and fix the other end of the upper telescopic bar 310.

[0047] The outer distance between the first outer top frame 211 and the second outer top frame 221 can be adjusted according to the needs to meet different folding requirements; the greater the relative distance between the first outer top frame 211 and the second outer top frame 221, the lower the force on the connecting strip 300.

[0048] Under the action of the first top mounting groove and the second top mounting groove, the stability of the upper telescopic strip 310 is enhanced. At the same time, it is convenient for the first outer top frame 211 and the first inner top frame 111 to cooperate and clamp and fix one end of the upper telescopic strip 310, and it is also convenient for the second outer top frame 221 and the second inner top frame 121 to cooperate and clamp and fix the other end of the upper telescopic strip 310.

[0049] The first top mounting groove is formed in the first outer top frame 211 and is arranged to be arched upward, and the second top mounting groove is formed in the second outer top frame 221 and is arranged to be arched upward; the matching area between the first outer top frame 211 and the first inner top frame 111 is effectively increased to enhance the relative fixing effect, and the matching area between the second outer top frame 221 and the second inner top frame 121 is effectively increased to enhance the relative fixing effect.

[0050] Alternatively, the first top mounting groove is formed in the first inner top frame 111 and is arranged to be concave downward, and the second top mounting groove is formed in the second inner top frame 121 and is arranged to be concave downward, and the two ends of the upper telescopic strip 310 are respectively fixed to the first top mounting groove of the first inner top frame 111 and the second top mounting groove of the second inner top frame 121; the matching area between the first outer top frame 211 and the first inner top frame 111 is effectively increased, and the relative fixing effect is enhanced; the matching area between the second outer top frame 221 and the second inner top frame 121 is effectively increased, and the relative fixing effect is enhanced.

[0051] The first outer shell 210 includes a first outer bottom frame 212, and the first outer bottom frame 212 has a first bottom mounting groove. The second outer shell 220 includes a second outer bottom frame 222, and the second outer bottom frame 222 has a second bottom mounting groove. The connecting bar 300 includes a lower telescopic bar 320 that is stretched or contracted under force, one end of the lower telescopic bar 320 is flatly fixed to the first bottom mounting groove, and the other end of the lower telescopic bar 320 is flatly fixed to the second bottom mounting groove; the first inner shell 110 includes a first inner bottom frame 112, and the second inner shell 120 includes a second inner bottom frame 122. The first outer bottom frame 212 and the first inner bottom frame 112 clamp and fix one end of the lower telescopic bar 320, and the second outer bottom frame 222 and the second inner bottom frame 122 clamp and fix the other end of the lower telescopic bar 320; the upper telescopic bar 310 and the lower telescopic bar 320 are arranged correspondingly.

[0052] In this way, under the action of the first bottom mounting groove and the second bottom mounting groove, the stability of the lower telescopic strip 320 is enhanced. At the same time, it is convenient for the first outer bottom frame 212 and the first inner bottom frame 112 to cooperate and clamp and fix one end of the lower telescopic strip 320, and it is also convenient for the second outer bottom frame 222 and the second inner bottom frame 122 to cooperate and clamp and fix the other end of the lower telescopic strip 320.

[0053] In addition, through the cooperation of the upper telescopic bar 310 and the lower telescopic bar 320, the first inner shell 110 and the second inner shell 120 can be more stable when they are unfolded or folded, and the first outer shell 210 and the second outer shell 220 can be more stable when they are unfolded or folded; at the same time, the upper telescopic bar 310 and the lower telescopic bar 320 have a pressure-sharing effect on each other, which helps to increase the service life of the upper telescopic bar 310 and the lower telescopic bar 320.

[0054] A plurality of shuttle bars 500 are provided between the inner shell 100 and the outer shell 200, and are arranged in sequence at intervals along the direction from the first outer top frame 211 to the first outer bottom frame 212; one end of the shuttle bar 500 is fixedly arranged with the second inner shell 120, and the first inner shell 110 is provided with a guide member 510, and the guide member 510 has a shuttle hole, and the other end of the shuttle bar 500 passes through the shuttle hole; when the first inner shell 110 and the second inner shell 120 are folded, the other end of the shuttle bar 500 shuttles in the direction toward the second inner shell 120 and does not leave the shuttle hole; in this way, when folded or unfolded, the shuttle bar 500 shuttles, thereby protecting the 3C products. At the same time, if the 3C products fall, each shuttle bar 500 plays a buffering and shock-absorbing role, thereby enhancing the protection effect on the 3C products.

[0055] The shuttle bar 500 is arranged in a long strip shape, so that the shuttle bar 500 can shuttle along the length direction.

[0056] The top surface of the other end of the shuttle bar 500 is arranged in an arc transition, which reduces the mutual wear between the shuttle bar 500 and the shuttle member when the shuttle bar 500 moves in a shuttle manner, thereby increasing the service life.

[0057] Furthermore, along the direction away from one end of the shuttle bar 500, the thickness of the other end of the shuttle bar 500 gradually decreases, and the bottom of the other end of the shuttle bar 500 is attached to the first inner shell 110, which is convenient for the movement of the shuttle bar 500. At the same time, it is convenient for the other end of the shuttle bar 500 to be attached to the first inner shell 110 and move, thereby reducing the shaking of the shuttle bar 500 during movement and improving the movement stability of the shuttle bar 500.

[0058] An inner partition area is formed between the first inner shell 110 and the second inner shell 120, and a notch 330 is formed on the connecting strip 300. The notch 330 is arranged in a recessed manner away from the folding direction, and the notch 330 is arranged corresponding to the inner partition area. When folded, the connecting strip 300 is symmetrically folded along the notch 330. In this way, under the action of the notch 330, the connecting strip 300 is facilitated to fold, while the force applied to the connecting strip 300 during folding is reduced, thereby increasing the service life of the connecting strip 300.

[0059] An outer partition area is formed between the first outer shell 210 and the second inner shell 220, and the notch 330 is arranged corresponding to the outer partition area; when folded, the outside of the connecting strip 300 extends to the outer partition area; in this way, under the action of the outer partition area, the connecting strip 300 is facilitated to fold, while reducing the force applied to the connecting strip 300 during folding, thereby increasing the service life of the connecting strip 300.

[0060] In addition, under the effect of the notch 330, the gap between the inner shell 200 and the outer shell 100 at the folding position is effectively reduced during folding, thereby improving the folding effect.

[0061] In this embodiment, the inner shell 100 has an inner shell thickness, the outer shell 200 has an outer shell thickness, and the connecting strip 300 has a wrapping layer; when the inner shell thickness is greater than the outer shell thickness, the outer shell 200 has an outer exposed portion, and the wrapping layer extends outward to cover the outer exposed portion; when the inner shell thickness is less than the outer shell thickness, the inner shell 100 has an inner exposed portion, and the wrapping layer extends inward to cover the inner exposed portion.

[0062] In this way, the relative fixing effect between the inner shell 100, the connecting bar 300 and the outer shell 200 is enhanced, and at the same time, the shock absorbing area of ​​the connecting bar 300 is increased, thereby improving the shock absorbing and anti-fall effects.
