Description

Technical Field

[0001] The utility model relates to a mobile phone case, in particular to a hinged wrist strap mobile phone case. Background Art

[0002] With the increasing popularity of smartphones in our daily lives, phone cases have become an essential accessory for users to protect their phones. By covering the outside of the phone, a phone case effectively protects it from scratches during daily use and also acts as a cushioning device in the event of a drop, reducing the risk of damage.

[0003] In order to further improve the safety and convenience of using mobile phones, some mobile phone protective cases are provided with finger rings or straps on the back. During use, fingers can be inserted into the finger rings or straps to prevent the risk of the mobile phone falling, thereby improving the safety and convenience of use.

[0004] However, for mobile phone protective cases with a shoulder strap, the shoulder strap is directly installed on the back of the shell, with one end of the shoulder strap fixedly connected to the shell by a rivet, and the other end of the shoulder strap slidingly connected to the rivet on the shell through a sliding hole, so that the shoulder strap can be pulled open and put on the finger. In mobile phone protective cases with this structure, the shoulder strap and rivet protrude from the back of the shell. On the one hand, the structure is not simple and there are problems such as poor user experience. For example, when putting the mobile phone into a pocket, the protruding shoulder strap and rivet will get stuck with the edge of the pocket, or when holding it with one hand, the palm will inevitably come into contact with the protruding shoulder strap and rivet. This foreign body sensation will affect the user experience and reduce the comfort of holding. On the other hand, because the shoulder strap is usually made of flexible material, the sliding hole can expand to a certain extent. When the sliding hole and rivet slide together, the sliding hole is easy to fall off the rivet, resulting in problems such as poor connection reliability. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the purpose of the present invention is to provide a hinged wrist strap mobile phone case.

[0006] To achieve the above-mentioned purpose, a hinged wrist strap mobile phone case according to an embodiment of the present invention includes:

[0007] A housing, wherein the front of the housing has a receiving slot suitable for receiving the electronic device, and the back of the housing is provided with a belt slot extending along a predetermined direction;

[0008] A hand strap, wherein the hand strap is made of a flexible material, and both ends of the hand strap are connected to the belt slot via hinges. The hand strap is flattened in the longitudinal direction of the belt slot and accommodated in the belt slot to form a folded state;

[0009] When the hand strap moves in a direction away from the shell under the action of external force, the hand strap can switch from the folded state to the open state. In the open state, the hand strap bends and forms a finger hole for the user's finger to pass through between the hand strap and the back side of the shell.

[0010] According to the hinged wrist strap mobile phone case provided by the embodiment of the present invention, a belt groove is set on the back of the shell, and the two ends of the flexible hand strap are connected to the belt groove by a hinge method, so that the hand strap can be completely stored in the belt groove. The problem of the traditional shoulder strap protruding outwards is avoided, and the overall structure of the mobile phone case is more simple and beautiful. When the hand strap function is needed, the hand strap can be easily lifted from the belt groove, and the rotation of the hinge makes the hand strap form an arc-shaped space suitable for the fingers to pass through, which not only ensures the stability of the hand strap during use, but also solves the foreign body sensation and jamming problems caused by the protrusion of the shoulder strap and rivets in the traditional design. At the same time, the hinge connection method is adopted to replace the traditional sliding hole and rivet structure, which significantly improves the reliability of the hand strap connection and avoids the risk of falling off caused by the expansion of the sliding hole. The hinged wrist strap mobile phone case of the present application greatly improves the user experience and safety reliability while ensuring functionality.

[0011] In addition, the hinged wrist strap mobile phone case according to the above embodiment of the present invention may also have the following additional technical features:

[0012] According to one embodiment of the present invention, the hinge is a torsion spring hinge. When the external force on the hand strap is removed, under the torsion of the torsion spring hinge, the hand strap is straightened and flattened in the length direction of the strap slot to restore to the folded state.

[0013] According to one embodiment of the present invention, the hinge comprises:

[0014] a first hinge, one end of the first hinge being pivotally connected to the strap slot via a first rotating shaft, and the other end of the first hinge being pivotally connected to the hand strap via a second rotating shaft;

[0017] A torsion spring, wherein the first torsion arm of the torsion spring is relatively fixed to the first hinge, and the second torsion arm of the torsion spring is relatively fixed to the shell, and when the external force on the hand strap is removed, the torsion force of the torsion spring causes the first hinge to rotate into the belt slot, and drives the hand strap to flatten and fold into the belt slot to form the folded state.

[0018] According to one embodiment of the present invention, a hinge portion is provided in the belt slot, and the hinge portion has two pivot portions that are opposite to each other in the width direction of the belt slot;

[0019] One end of the first hinge is located between the two pivoting portions, and a notch is provided at one end of the first hinge. The torsion spring is located in the notch. The first rotating shaft passes through the torsion spring and pivotally connects one end of the first hinge to the pivoting portion.

[0020] According to one embodiment of the present invention, the hinge comprises:

[0021] a second hinge, the second hinge being fixed in the belt slot;

[0022] a third hinge, one end of the third hinge being pivotally connected to the second hinge via a third rotating shaft, and the other end of the third hinge being pivotally connected to the hand strap via a fourth rotating shaft;

[0023] When the hand strap switches from the open state to the folded state, the third hinges of the two hinges rotate in a direction away from each other;

[0024] A torsion spring, wherein the first torsion arm of the torsion spring is relatively fixed to the second hinge, and the second torsion arm of the torsion spring is relatively fixed to the third hinge, and when the external force on the hand strap is removed, the torsion force of the torsion spring causes the third hinge to rotate into the belt slot, and drives the hand strap to flatten and fold into the belt slot to form the folded state.

[0025] According to one embodiment of the present invention, a bracket groove is further provided on the back of the housing, and a bracket capable of rotating between a first position and a second position is provided in the bracket groove;

[0026] When the bracket is located at the first position, the bracket is received in the bracket slot. When the bracket is rotated to the second position, the bracket forms a predetermined angle with the shell and can support the shell on an external bearing surface to form a predetermined viewing angle.

[0027] According to one embodiment of the present invention, the bracket is a U-shaped bracket, and the belt groove includes a first groove section and a second groove section connected in the length direction thereof;

[0028] The width of the second section of the groove is greater than that of the first section of the groove. When the hand strap is flattened and folded in the strap groove to form the folded state, the U-shaped bracket groove is defined between the hand strap and the peripheral wall of the second section of the groove.

[0029] According to an embodiment of the present invention, a magnetic member is provided on the shell, and the magnetic member is adjacent to the end of the second section groove, for adsorbing and fixing the U-shaped bracket when the U-shaped bracket is rotated and retracted into the bracket groove.

[0030] According to one embodiment of the present invention, a stop surface is formed at the connection between the first groove section and the second groove section;

[0031] When the bracket rotates to the second position, the stop surface abuts against the bracket, so that the bracket stops at the second position and forms the predetermined angle with the housing.

[0067] The hinged wrist strap mobile phone case according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0068] Reference Figures 1 to 8 As shown, the hinged wrist strap mobile phone case provided according to an embodiment of the present invention includes a housing 10 and a wrist strap 20.

[0069] Specifically, the front of the housing 10 has a receiving slot H101 suitable for accommodating an electronic device. The size and shape of this receiving slot H101 are adapted to the electronic device to be protected, ensuring that the electronic device can be securely installed within the protective case. The back of the housing 10 has a belt slot H102 extending in a predetermined direction, for example, along the length or width of the housing 10. This belt slot H102 is used to accommodate the hand strap 20.

[0070] The hand strap 20 is made of a flexible material, which ensures both comfort and flexibility. For example, the flexible material can be silicone, leather, or other materials. The ends of the hand strap 20 are connected to the strap slot H102 via hinges 11. The hand strap 20 is flattened along the length of the strap slot H102 and accommodated within the strap slot H102 to form a collapsed state.

[0071] When the hand strap 20 moves in a direction away from the shell 10 under the action of external force, the hand strap 20 can switch from the folded state to the open state. In the open state, the hand strap 20 bends and forms a finger hole between it and the back side of the shell 10 for the user's finger to pass through.

[0072] That is, when not in use, the hand strap 20 can be completely flattened and stored within the hand strap slot H102, forming a folded state, keeping the back of the phone case flat. During use, the user can apply external force to pull the hand strap 20 out of the hand strap slot H102, at which point the hand strap 20 switches from the folded state to the open state via the rotation of the hinge 11. In the open state, the flexible hand strap 20 naturally forms an arc, forming a finger hole between the flexible hand strap 20 and the back of the phone case 10 for the user to insert their fingers, providing stable grip support.

[0073] According to the hinged wristband mobile phone case provided by the embodiment of the utility model, by providing a belt slot H102 on the back of the housing 10 and connecting the two ends of the flexible hand strap 20 within the belt slot H102 using a hinge 11, the hand strap 20 can be completely stored in the belt slot H102 in a folded state, avoiding the problem of protruding straps in traditional shoulder straps and making the overall structure of the mobile phone case more simple and beautiful. When the hand strap 20 function is needed, the hand strap 20 can be easily lifted from the belt slot H102. The rotation of the hinge 11 forms an arc-shaped space suitable for the hand strap 20 to pass through. This not only ensures the stability of the hand strap 20 during use, but also solves the foreign body sensation and jamming problems caused by the protruding shoulder strap and rivets in traditional designs. At the same time, the hinge 11 connection method replaces the traditional sliding hole and rivet structure, significantly improving the reliability of the hand strap 20 connection and avoiding the risk of falling off due to the expansion of the sliding hole. The hinged wristband mobile phone case of the present application greatly enhances the user experience and safety reliability while ensuring functionality.

[0074] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the hinge 11 is a torsion spring hinge 11. When the external force on the hand strap 20 is removed, under the action of the torsion force of the torsion spring hinge 11, the hand strap 20 is straightened and flattened in the length direction of the strap groove H102 to restore to the folded state.

[0075] In this embodiment, the hinge 11 is a torsion spring hinge 11 . This hinge 11 structure not only has the rotation function of an ordinary hinge 11 , but also has the function of automatically resetting when the hand strap 20 is released, provided by the torsion spring 112 .

[0076] During use, when the user pulls up the hand strap 20, the torsion spring 112 is twisted and stores elastic potential energy. When the user removes the external force applied to the hand strap 20, the torsion spring 112 releases the stored potential energy, causing the hinge 11 to automatically rotate in the opposite direction and return to its initial position, thereby driving the hand strap 20 to be automatically straightened and flattened along the length direction of the strap groove H102, and finally returning to the folded state completely housed in the strap groove H102.

[0077] The torsion spring hinge 11 enables the automatic folding of the hand strap 20, significantly improving its usability. After using the hand strap 20, the user no longer needs to manually press it into the slot H102. Simply releasing the hand strap 20 automatically returns to the folded position under the force of the torsion spring 112, providing a smoother and more natural user experience. Furthermore, the torsion spring 112 provides a moderate damping force, ensuring that the hand strap 20 fits tightly against the finger when in the open position, further ensuring a more stable fit and preventing it from shaking or accidentally falling off. This damping property ensures stability during use while also preventing the hand strap 20 from being pulled up and opened properly. Furthermore, the torsion spring 112 ensures that the hand strap 20 fits snugly against the bottom of the slot H102 when folded, preventing the hand strap 20 from shaking or tilting within the slot H102 and maintaining the product's smooth appearance. This conforming fit also prevents the hand strap 20 from scratching or snagging on other objects.

[0078] Reference Figures 3 to 6 As shown, in one embodiment of the present invention, the hinge 11 includes a first hinge 111, one end of which is pivotally connected to the strap slot H102 via a first rotating shaft, and the other end of which is pivotally connected to the hand strap 20 via a second rotating shaft. This dual-rotating shaft pivot design allows the hand strap 20 to move with greater freedom, allowing for smoother and more natural folding and opening.

[0079] When the hand strap 20 switches from the open state to the closed state, the first hinges 111 of the two hinges 11 rotate away from each other. Since the two first hinges 111 are respectively provided at the two ends of the hand strap 20, when the two first hinges 111 rotate away from each other, the two ends of the hand strap 20 can be driven to move away from each other, thereby straightening and flattening the hand strap 20 along the length direction of the strap groove H102.

[0080] For example: Figure 6 In the example, when the hand strap 20 is in use, when the user pulls up the hand strap 20, the hand strap 20 drives the first hinges 111 at both ends to rotate upward. At this time, the two first hinges 111 move toward each other, thereby providing conditions for the hand strap 20 to bend, so that the hand strap 20 can bend to form finger holes when it is pulled up. When the user removes the pulling force on the hand strap 20 and switches the hand strap 20 from the open state to the folded state, the first hinges 111 in the two hinges 11 rotate downward, that is, the two first hinges 111 rotate away from each other, thereby moving the two ends of the hand strap 20 away from each other, and then being able to be straightened and flattened and evenly stored in the strap groove H102, avoiding wrinkles or deformation during the folding process.

[0081] In this embodiment, the coordinated reverse movement of the hinges 11 at both ends of the hand strap 20 ensures that the hand strap 20 can be straightened and flattened during the folding process, preventing wrinkles or deformation, and improving the flatness and aesthetics in the folded state.

[0082] Reference Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the hinge 11 also includes a torsion spring 112, the first torsion arm of the torsion spring 112 is relatively fixed to the first hinge 111, and the second torsion arm of the torsion spring 112 is relatively fixed to the shell 10, and when the external force on the hand strap 20 is removed, the torsion force of the torsion spring 112 causes the first hinge 111 to rotate into the belt slot H102, and drives the hand strap 20 to flatten and fold into the belt slot H102 to form the folded state.

[0083] When the wrist strap 20 is open, the torsion spring 112 is twisted and deformed under load, storing elastic potential energy. When the user removes the external force applied to the wrist strap 20, the torsion spring 112 releases this stored potential energy, generating a torque that causes the first hinge 111 to rotate toward the inner portion of the wrist strap slot H102. This torque pulls the end of the wrist strap 20 toward the end of the wrist strap slot H102, ultimately flattening the wrist strap 20 along the length of the wrist strap slot H102 and completely retracting it into the closed position.

[0084] As described above, the design of torsion spring 112 enables the automatic folding function of wrist strap 20. By converting the elastic potential energy of torsion spring 112, wrist strap 20 automatically returns to the folded position without manual operation by the user. This automated folding method greatly improves the user-friendliness of the product, making it easier and more convenient to operate.

[0085] Reference Figure 3 and Figure 4 As shown, in one embodiment of the present invention, a hinge portion 1011 is provided in the belt slot H102 , and the hinge portion 1011 has two pivot portions 1011 a opposite to each other in the width direction of the belt slot H102 .

[0086] One end of the first hinge 111 is located between the two pivoting portions 1011a, and one end of the first hinge 111 is provided with a notch, the torsion spring 112 is located in the notch, and the first rotating shaft passes through the torsion spring 112 and pivotally connects one end of the first hinge 111 to the pivoting portion 1011a.

[0087] In this embodiment, a hinged portion 1011 having two opposing pivoting portions 1011a is disposed within slot H102, and one end of the first hinge 111 is positioned between the two pivoting portions 1011a, thereby forming a stable rotational support structure for hinge 11. A notch provided at the end of the first hinge 111 provides installation space for a torsion spring 112, allowing the torsion spring 112 to be compactly mounted within the notch. A first rotating shaft extends through the torsion spring 112 and connects the first hinge 111 to the pivoting portion 1011a, achieving an integrated assembly of the torsion spring 112, the first hinge 111, and the pivoting portion 1011a. This results in a more compact and lightweight structure and more stable and reliable pivoting.

[0088] It should be understood that, in the present embodiment, the hinge 11 only requires one hinge (i.e., the first hinge 111), and the first hinge 111 is directly pivotally connected to the hinge portion 1011 of the shell 10. That is, the end of the hand strap 20 is pivotally connected to the shell 10 using one hinge and a torsion spring 112. The hinge 11 structure implemented by such a single hinge can significantly simplify the structure. In the scenario where the thickness of the mobile phone case is relatively small, the pivotal connection can be achieved without increasing the thickness of the mobile phone case as much as possible, and the reliability of its pivotal connection is also guaranteed.

[0089] In another embodiment of the present invention, the hinge 11 includes a second hinge, a third hinge, and a torsion spring 112. The second hinge is fixed in the strap slot H102. One end of the third hinge is pivotally connected to the second hinge via a third shaft, and the other end of the third hinge is pivotally connected to the wrist strap 20 via a fourth shaft.

[0090] When the hand strap 20 switches from the open state to the folded state, the third hinges in the two hinges 11 rotate away from each other.

[0091] The first torsion arm of the torsion spring 112 is relatively fixed to the second hinge, and the second torsion arm of the torsion spring 112 is relatively fixed to the third hinge. When the external force on the hand strap 20 is removed, the torsion of the torsion spring 112 causes the third hinge to rotate into the belt slot H102, and drives the hand strap 20 to flatten and fold into the belt slot H102 to form the folded state.

[0092] This embodiment differs from the above-described embodiment in that it employs a dual-hinge design. The second hinge is secured within the belt slot H102 as a reference member through the cooperation of the second hinge and the third hinge. The third hinge forms a pivot point with the second hinge via a third rotating shaft. Simultaneously, the third hinge forms a pivot point with the hand strap 20 via a fourth rotating shaft. The dual-hinge design achieves the same pivotal connection and also ensures a flexible motion trajectory for the third hinge.

[0093] Compared to a single-hinge structure, the double-hinge structure does not require a pivoting member on the housing 10; instead, the second hinge is simply secured in the slot H102, simplifying the structure of the housing 10. Furthermore, the coordinated design of the torsion spring 112 with the second and third hinges makes the pivoting structure more reliable and stable.

[0094] Reference Figures 2 to 4 and Figure 7 As shown, in some embodiments of the present invention, a bracket groove H103 is further provided on the back of the housing 10 , and a bracket 12 capable of rotating between a first position and a second position is provided in the bracket groove H103 .

[0095] When the bracket 12 is located at the first position, the bracket 12 is received in the bracket slot H103. When the bracket 12 is rotated to the second position, the bracket 12 forms a predetermined angle with the shell 10 and can support the shell 10 on an external bearing surface to form a predetermined viewing angle.

[0096] This embodiment achieves the support function of the phone case by providing a support slot H103 on the back of the case 10 and disposing a rotatable support 12 therein. Support 12 can be switched between a first position and a second position. The first position is the stowed position, where support 12 is fully retracted within support slot H103, maintaining the flatness of the back of the phone case. The second position is the support position, where support 12 is rotated out of support slot H103 and forms a predetermined angle with the case 10, providing stable support for the phone, allowing it to be placed at a suitable viewing angle on a table or other support surface.

[0097] The design of the bracket 12 and bracket slot H103 allows the bracket 12 to be completely retracted, preventing its exposure from interfering with the phone case's storage and user experience. When not in use, the bracket 12 can be simply retracted into the bracket slot H103. During use, simply rotating the bracket 12 to the second position creates a predetermined angle, ensuring stable placement of the phone and providing a comfortable viewing experience. Furthermore, this rotatable bracket 12 allows users to quickly switch between different phone placement positions, enhancing product convenience and meeting diverse user needs.

[0098] Reference Figures 3 and 4 As shown, in one embodiment of the present invention, the bracket 12 is a U-shaped bracket, and the belt groove H102 includes a first groove section H102a and a second groove section H102b connected in the length direction thereof.

[0099] The width of the second section groove H102b is greater than that of the first section groove H102a. When the hand strap 20 is flattened and folded in the strap groove H102 to form the folded state, the U-shaped bracket groove H103 is defined between the hand strap 20 and the peripheral wall of the second section groove H102b.

[0100] That is, in this embodiment, the strap slot H102 is divided into two sections along its length: a first section H102a and a second section H102b. The width of the second section H102b is greater than that of the first section H102a. This width difference creates a U-shaped space between the strap 20 and the wall of the second section H102b when the strap is folded, which serves as the bracket slot H103 of the U-shaped frame.

[0101] By structurally integrating the bracket slot H103 with the strap slot H102, the need for a separate bracket slot H103 is avoided, thereby reducing the number of slots on the back of the housing 10, resulting in a simpler product structure and a more aesthetically pleasing appearance. Furthermore, the complexity of mold processing is reduced, which helps improve product production efficiency and reduce manufacturing costs. Furthermore, by utilizing the space between the hand strap 20 and the peripheral wall of the second section slot H102b as the bracket slot H103, the existing structural space is fully utilized, improving space utilization. When the hand strap 20 is in the folded state, the naturally formed U-shaped space, due to the wider second section slot H102b, can perfectly accommodate the U-shaped frame, allowing the bracket 12 to be completely hidden and maintaining the flatness of the product's back.

[0102] For example, the two ends of the U-shaped frame are bent outward to form a pivot portion, and an axis hole is provided on both side walls of the bracket groove H103. The pivot portions at both ends of the U-shaped frame are pivotally matched with the axis holes on both side walls of the bracket groove H103 one by one. In this way, the pivot connection between the U-shaped frame and the shell 10 can be realized.

[0103] Preferably, if Figure 8 As shown, a damping sleeve 121 is provided on the rotating shaft portion. The damping sleeve 121 can be made of soft rubber material, such as rubber, silicone, etc. When the rotating shaft portion is matched with the shaft hole, the damping sleeve 121 can increase the rotational damping between the shaft hole and the shaft hole, ensuring that the U-shaped frame is not easy to rotate at will, thereby improving the user experience.

[0104] In some embodiments of the present invention, a magnetic member 102 is provided on the housing 10. The magnetic member 102 is located adjacent to the end of the second slot H102b and is used to secure the U-shaped bracket when the U-shaped bracket is rotated and retracted into the bracket slot H103. The magnetic member 102 may be a permanent magnet. As a result, when the U-shaped bracket is rotated and retracted into the bracket slot H103, the magnetic member 102 securely and stably holds the U-shaped bracket within the bracket slot H103, preventing the U-shaped bracket from easily falling out of the bracket slot H103.

[0105] It is understandable that in other embodiments, in order to prevent the U-shaped frame from falling off from the bracket slot H103, other methods can be used to replace or combine with the magnetic member 102, such as providing a retaining structure on the side wall of the bracket slot H103.

[0106] Reference Figure 4 As shown, in one embodiment of the present invention, a stop surface S10 is formed at the junction of the first groove H102a and the second groove H102b. When the bracket 12 rotates to the second position, the stop surface S10 abuts against the bracket 12, causing the bracket 12 to stop at the second position and form the predetermined angle with the housing 10.

[0107] That is to say, since the widths of the first groove H102a and the second groove H102b are different, a stop surface S10 is formed at the connection between the first groove H102a and the second groove H102b, and the position where the U-shaped frame is pivotally connected to the shell 10 is adjacent to the stop surface S10. In this way, when the bracket 12 rotates from the first position to the second position, the bracket 12 will conflict with the stop surface S10, thereby naturally forming a mechanical limit, so that the bracket 12 stays stably in the second position and maintains a predetermined angle with the shell 10.

[0108] This embodiment forms a stop surface S10 at the junction of the first groove H102a and the second groove H102b, providing a simple and reliable positioning structure for the bracket 12. This design eliminates the need for additional positioning components and directly utilizes the geometric characteristics of the groove H102 to position the bracket 12, saving component costs, simplifying the product structure, and improving product reliability.

[0109] Reference Figures 1 to 4 As shown, in one embodiment of the present invention, a belt groove H102 extends from the back of the housing 10 to the receiving groove H101. A cover plate 101 is embedded in the bottom surface of the receiving groove H101 to close the belt groove H102. The hinge portion 1011 is formed on the cover plate 101. For example, the cover plate 101 can be fixed to the housing 10 by snap fasteners, screws, bonding, or any other suitable fixing method.

[0110] In this embodiment, the belt groove H102 is set as a through structure, and then the belt groove H102 is closed by the cover plate 101, which can facilitate the structural processing of the shell 10. Since the cover plate 101 needs to be provided with a hinge part 1011 and other structures, the cover plate 101 is processed separately, making the processing technology simpler.
