Description

Technical Field

[0001] This invention relates to the field of mobile phone cases, specifically to a mobile phone case with a foldable back strap that can be converted into a support stand. Background Technology

[0002] Currently, mainstream multi-functional mobile phone cases on the market fall into two categories: one type only has an independent folding stand, and the other type only has a neck strap or crossbody strap. Both types have the problem of limited functionality and structural interference, making it difficult to simultaneously meet the two high-frequency usage scenarios of carrying on the back and standing upright on a desktop.

[0003] Phone cases with crossbody straps or neck straps on the market can only be used for hanging and carrying without any supporting structure. When placed on a desk at home or in the office, they cannot be tilted or placed upright on their own. Watching videos or participating in online meetings still requires holding the phone, which can easily cause hand fatigue and soreness after a long time. In addition, these external straps and neck straps are easy to tangle and become messy when not in use, resulting in a poor carrying experience. Summary of the Invention

[0004] To address the aforementioned issues, we offer a phone case with a foldable shoulder strap that can be converted into a support stand. This aims to solve the problem that existing phone cases on the market with crossbody straps or neck straps only provide a hanging function and lack an independent support structure. When used at home or on an office desk, users cannot independently tilt or stand the phone upright, and still need to hold the phone while watching videos or participating in online meetings, which can easily cause hand fatigue and soreness after prolonged use.

[0005] To address the existing technical problems, the present invention provides the following technical solution: a mobile phone case with a foldable back strap that can be converted into a support bracket, comprising a mobile phone case, wherein a positioning piece is fitted on the back of the mobile phone case, the back of the mobile phone case is connected to the positioning piece via a mating plate, and an inner support frame and an outer support frame are connected to one side of the positioning piece; The back of the phone case is provided with an installation cavity, in which a mating plate is installed and a magnetic block is embedded.

[0006] One end of the outer support frame is foldably connected to one end of the end frame. The inner and outer support frames are foldably supported on the back of the phone case to support the phone case in a tilted state. The inner support frame and the outer support frame are stretched and unfolded in sequence to form a back strap structure with the end frame. The back strap structure is used for hanging and wearing the mobile phone case.

[0007] As a mobile phone protective case with a foldable back strap that can be converted into a support bracket according to the present invention, preferably, the outer support bracket is composed of a third fold strip, a fourth fold strip and a fifth fold strip, the two ends of the fourth fold strip are respectively connected to the third fold strip and the fifth fold strip, and the connecting ends of the fourth fold strip and the third fold strip and the fifth fold strip can be bent and adjusted.

[0008] As a mobile phone protective case with a foldable back strap that can be converted into a support bracket according to the present invention, preferably, the other end of the fifth fold strip is foldably and integrally connected to the end frame, the third, fourth and fifth fold strips are of the same length, and the width between the inner walls of the third, fourth and fifth fold strips gradually increases in an adaptive manner.

[0009] As a mobile phone protective case with a foldable back strap that can be converted into a support bracket according to the present invention, preferably, the inner support frame is composed of a center strip, a first folding strip, and a second folding strip, and the two ends of the first folding strip are respectively foldably and integrally connected to the center strip and the second folding strip.

[0010] As a mobile phone protective case with a foldable back strap that can be converted into a support bracket according to the present invention, preferably, the first fold strip is a U-shaped structure, the internal size of the first fold strip is adapted to the size of the center strip, and the maximum size of the first fold strip is adapted to the internal size of the second fold strip.

[0011] As a mobile phone protective case that can be converted into a support bracket according to the present invention, preferably, the first fold strip, the second fold strip, the third fold strip, the fourth fold strip, the fifth fold strip and the end frame are connected in sequence to form a strap structure.

[0012] The advantages of this invention compared to the prior art are: 1. Bend the center strip, first fold strip, second fold strip, third fold strip, fourth fold strip, and fifth fold strip along their joints to form an outer support frame and an inner support frame that rests on one side of the phone case.

[0021] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0022] See Figures 1-6 As shown, the present invention provides the following technical solution: a mobile phone case with a foldable back strap that can be converted into a support bracket, including a mobile phone case 1, a positioning piece 2 is assembled on the back of the mobile phone case 1, the back of the mobile phone case 1 is connected to the positioning piece 2 through a docking plate 11, and an inner support frame 5 and an outer support frame 4 are connected to one side of the positioning piece 2. The inner support frame 5 and the outer support frame 4 are made of silicone and magnetic sheets, specifically with magnetic sheets embedded in the silicone. In use, the inner support frame 5 and the outer support frame 4 can magnetically engage with the magnetic block 12 in the positioning piece 2, thus maintaining their folded state.

[0023] After use, the silicone outer shell of the inner support frame 5 and the outer support frame 4 will automatically return to its folded storage state due to the elasticity of the silicone material. (See attached image.) Figure 3 As described above, after folding and storing, the magnetic sheets inside the inner support frame 5 and the outer support frame 4 will further attract together with the magnetic block 12 in the docking plate 11, thereby stably maintaining the folded and stored state.

[0024] The back of the phone case 1 is provided with an installation cavity 13, in which a docking plate 11 is installed and a magnetic block 12 is embedded. One end of the outer support frame 4 is foldably connected to one end of the end frame 3. The inner support frame 5 and the outer support frame 4 are foldably supported on the back of the phone case 1 to support the phone case in a tilted state 1. After the inner support frame 5 and the outer support frame 4 are stretched and unfolded in sequence, they form a strap structure with the end frame 3. The strap structure is used to hang the mobile phone case 1.

[0025] When the inner support frame 5 and the outer support frame 4 are folded, their ends will press against the surfaces of the phone case 1 and the shelf, allowing the phone case 1 to be placed at an angle. The inner support frame 5 and the outer support frame 4 will also form a triangular support structure with the shelf.

[0026] Both the outer support frame 4 and the inner support frame 5 are made of Shore A60 high-toughness TPU material through integral extrusion molding.

[0027] Bracket mode switching operation: Bend the center strip 31, the first fold strip 32, the second fold strip 33, the third fold strip 34, the fourth fold strip 35, and the fifth fold strip 36 inward along the joint of the thin fold lines between the components. The center strip 31 can be bent and positioned on one side of the positioning piece 2 as a support base. The center strip 31, the first fold strip 32, and the second fold strip 33 are folded to the corresponding side to form the inner support frame 5 double-layer support arm. The third fold strip 34, the fourth fold strip 35, and the fifth fold strip 36 are also bent to the corresponding side to form the outer support frame 4. The inner support frame 5 and the outer support frame 4 are folded to form several sets of triangular support structures. The triangular support structures are supported on the back of the phone case 1. The rigidity of each fold strip after bending locks the tilt angle, so that the phone case 1 can maintain a stable tilted position when in use. See Figure 4 and Figure 5 As shown, the outer support frame 4 is composed of a third folding strip 34, a fourth folding strip 35 and a fifth folding strip 36. The two ends of the fourth folding strip 35 are connected to the third folding strip 34 and the fifth folding strip 36 respectively, and the joint ends of the fourth folding strip 35 with the third folding strip 34 and the fifth folding strip 36 can be bent and adjusted. When in use: Fold the third fold strip 34 to one side along the end that is connected to the second fold strip 33, and fold the fifth fold strip 36 in the opposite direction at one end of the fourth fold strip 35, so that the three form two sets of triangular support structures. When switching the shoulder strap mode, the third fold strip 34, the fourth fold strip 35 and the fifth fold strip 36 are stretched outward, and the three are straightened along the fold lines to form an outer support strip section, which serves as the outer load-bearing section of the shoulder strap. See Figure 4 and Figure 5As shown, the other end of the fifth fold strip 36 is bent and integrally connected to the end frame 3. The third fold strip 34, the fourth fold strip 35 and the fifth fold strip 36 are of the same length, and the width between the inner walls of the third fold strip 34, the fourth fold strip 35 and the fifth fold strip 36 gradually increases in an adaptive manner.

[0028] When in use: When folded into the support state, the third fold strip 34 can be completely embedded in the inner groove of the fourth fold strip 35, and the fourth fold strip 35 is embedded in the inner groove of the fifth fold strip 36. The three fold strips are nested and stacked to reduce the thickness of the support when stored. When fully unfolded to form the carrying strap, the progressively widening inner grooves completely separate, and the three folded strips are connected in a straight line, combining with the end frame 3 to form a complete outer carrying strap section; See Figure 4 and Figure 5 As shown, the inner support frame 5 is composed of a center strip 31, a first folding strip 32, and a second folding strip 33. The two ends of the first folding strip 32 are respectively connected to the center strip 31 and the second folding strip 33 in a bendable integrated manner.

[0029] When switching the support mode, the center strip 31 is used as a fixed base, and the first fold strip 32 is folded upward along the two end folds, so that the center strip 31, the first fold strip 32 and the open area of ​​the phone case 1 form a triangular support structure. Simultaneously, the joint ends of the second fold strip 33 and the first fold strip 32 abut against the back of the phone case 1. The second fold strip 33, under the force of the third fold strip 34 opening, will further expand to one side, thus forming a triangular support structure between the third fold strip 34 and the second fold strip 33. This, combined with the outer support frame 4, forms multiple working triangular support structures, enhancing support stability. When switching the shoulder strap mode, straighten the first fold strip 32, the second fold strip 33 and the third fold strip 34 outwards. The three are connected in a straight line to form the inner bearing section of the shoulder strap, which is spliced ​​with the outer support frame 4. See Figure 4 and Figure 5 As shown, the first fold strip 32 has a U-shaped structure, the internal dimensions of the first fold strip 32 are adapted to the dimensions of the center strip 31, and the maximum dimension of the first fold strip 32 is adapted to the internal dimensions of the second fold strip 33.

[0030] When in use: When folded into a support state, the center strip 31 is embedded in the U-shaped groove of the first folding strip 32, and the first folding strip 32 is embedded in the groove of the second folding strip 33. The three-layer components of the inner support frame 5 are nested and folded together, greatly reducing the thickness and fitting the back of the phone case 1 without any protrusions. When unfolded into a shoulder strap, each fold unfolds straight to form a flat shoulder strap contact surface, improving wearing comfort; See Figure 4 and Figure 5As shown, the first fold strip 32, the second fold strip 33, the third fold strip 34, the fourth fold strip 35, the fifth fold strip 36 and the end frame 3 are connected in sequence to form the shoulder strap structure.

[0031] When in use: fully unfold all the folds of the inner support frame 5 and the outer support frame 4 along the butt joint folds. The center strip 31 serves as the fixed base point for one end of the shoulder strap. Unfold the first fold strip 32, the second fold strip 33, the third fold strip 34, the fourth fold strip 35, and the fifth fold strip 36 in sequence. Finally, the end frame 3 connected to the fifth fold strip 36 extends to the other end of the shoulder strap. The straight sections are connected in series to form a closed ring shoulder strap. When using, put the ring strap on your shoulders and chest. The weight of the phone is evenly distributed by the overall toughness of the continuous folds, so that you can carry the phone case on your back or crossbody, freeing your hands. Working principle: The principle of the bracket support: With the positioning piece 2 and the center strip 31 as the fixed base, the first fold strip 32 and the second fold strip 33 of the inner support frame 5 are bent to the corresponding side. At the same time, the third fold strip 34, the fourth fold strip 35 and the fifth fold strip 36 of the outer support frame 4 are also folded. The inner support frame 5 and the outer support frame 4 form multiple triangular support structures between themselves and the phone case 1 through the folding of the above components. The rigid deformation after the fold strips are bent provides support force, stably supports the phone case 1 and freely adjusts the tilt angle. The multi-layered nested structure significantly reduces the thickness of the support storage, allowing it to completely fit the back of the phone when not in use.

[0032] The principle of the carrying strap: All the inner and outer folds are fully stretched outward along the fold lines. The center strip 31, the first fold strip 32, and the second fold strip 33 are connected to form the inner section of the strap. The third fold strip 34, the fourth fold strip 35, and the fifth fold strip 36 are connected to form the outer section of the strap. The two sections are connected end to end by the end frame 3 to form a closed ring strap. The grooves, which gradually widen with each fold, unfold to form a flat and wide bearing surface, evenly distributing the load pressure. Relying on the overall toughness of the plastic, it can be worn in two ways: crossbody or chest carry, allowing the phone case to be carried on your person and freeing your hands.
