Mobile phone case

[0001] The present application claims priority to Chinese Patent Application No. 202422716237.1, filed on November 07, 2024, the entire contents of which are incorporated herein by reference.

[0002] TECHNICAL FIELD

[0003] The present application relates to the technical field of mobile phone cases, and in particular to a mobile phone case. BACKGROUND

[0004] With the popularity of smart phones in people's daily life, mobile phone protective cases have become essential accessories for users to protect their phones. Mobile phone protective cases can effectively prevent scratches on the phone during daily use by wrapping around the outside of the phone. In the event of a phone drop, it can also serve as a buffer to reduce the risk of damage to the phone.

[0005] To further improve the safety and convenience of using a mobile phone, some mobile phone protective cases have a back strap or a back strap on the back. In use, the finger can be inserted into the finger ring or the back strap, which can prevent the phone from falling and improve the safety and convenience of use.

[0006] However, for mobile phone protective cases with a back strap, the back strap is directly provided on the back of the case, one end of the back strap is fixedly connected to the case by a rivet, and the other end of the back strap is slidably connected to the rivet on the case through a sliding hole, so that the back strap can be pulled apart and fitted on the finger. The mobile phone protective case of this structure has the back strap and the rivet protruding from the back of the case. On the one hand, the structure is not simple, and there are problems such as poor user experience, for example, when the phone is put into the pocket, the protruding back strap and rivet are stuck with the edge of the pocket, or when using a single hand, the palm inevitably contacts the protruding back strap and rivet, which affects the user experience and reduces the comfort of holding. On the other hand, since the back strap is usually made of flexible material and the sliding hole can expand to a certain extent, the sliding hole is easily detached from the rivet when the sliding hole and the rivet are slidably connected, resulting in poor connection reliability. SUMMARY

[0007] The main purpose of the present application is to provide a mobile phone case, which aims to at least solve one of the technical problems in the related art.

[0008] To achieve the above-mentioned purpose, the mobile phone case provided by the present application comprises:

[0009] a case, the front surface of the case having a receiving groove adapted to receive an electronic device, the back surface of the case being provided with a groove; and

[0010] The wrist strap has two ends connected to the housing, and has a closed state and an open state.

[0011] When the hand strap is in the closed state, it is folded into the groove. When the hand strap is in the open state, at least a portion of the structure of the hand strap is located outside the groove, forming a finger hole between it and the back of the housing, through which the user's fingers can pass.

[0012] In one embodiment, the wrist strap can automatically return from the open state to the closed state.

[0013] In one embodiment, the phone case further includes a hinge, the two ends of which are respectively connected to the end of the wrist strap and the case.

[0014] In one embodiment, 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 groove to return to the closed state.

[0015] In one embodiment, the hinge includes:

[0016] The first hinge, two first hinges are respectively located at both ends of the hand strap, one end of the first hinge being rotatably connected to the strap groove; and

[0017] A torsion spring is used to drive the first hinge to rotate into the groove, so as to drive the hand strap back to the closed state.

[0018] In one embodiment, the hinge includes a second hinge and a third hinge, the second hinge being connected to the groove, and the two ends of the third hinge being rotatably connected to the second hinge and the hand strap, respectively.

[0019] In one embodiment, the hinge further includes a torsion spring, the first torsion arm of which is fixed relative to the second hinge, the second torsion arm of which is fixed relative to the third hinge, and when the external force on the hand strap is removed, the torque of the torsion spring causes the third hinge to rotate into the strap groove, thereby driving the hand strap to return to the closed state.

[0020] In one embodiment, the wrist strap is made of a flexible material.

[0021] In one embodiment, the phone case further includes a bracket, which is rotatably connected to the case and has a first position and a second position;

[0022] When the bracket is in the first position, it is retracted into the housing. When the bracket is in the second position, it is set at an angle to the housing and can support the housing on an external bearing surface.

[0023] This application also proposes a mobile phone case, including:

[0024] A housing having a receiving slot on its front side suitable for housing an electronic device, and a groove on its back side extending in a predetermined direction;

[0025] The wrist strap is made of a flexible material. Both ends of the wrist strap are connected to the groove by hinges. The wrist strap is flattened along the length of the groove and housed in the groove to form a folded state.

[0026] When the wrist strap moves away from the housing under the action of an external force, the wrist strap can switch from the closed state to the open state. In the open state, the wrist strap bends and forms a finger hole between itself and the back of the housing, through which the user's fingers can pass.

[0027] In one embodiment, 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 groove to return to the closed state.

[0028] In one embodiment, the hinge includes:

[0029] The first hinge has one end pivotally connected to the groove of the belt via a first pivot, and the other end pivotally connected to the hand strap via a second pivot.

[0030] When the wrist strap switches from the open state to the closed state, the first hinges of the two hinges rotate in a direction away from each other.

[0031] In one embodiment, the hinge further includes:

[0032] A torsion spring, wherein the first torsion arm of the torsion spring is fixed relative to the first hinge, and the second torsion arm of the torsion spring is fixed relative to the housing, 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 strap groove, and drives the hand strap to flatten and close into the strap groove to form the closed state.

[0033] In one embodiment, the groove is provided with a hinge portion, the hinge portion having two pivot portions opposite each other in the width direction of the groove;

[0034] One end of the first hinge is located between the two pivot portions, and one end of the first hinge has a notch. The torsion spring is located in the notch, and the first pivot passes through the torsion spring and pivotally connects one end of the first hinge to the pivot portion.

[0035] In one embodiment, the hinge includes:

[0036] The second hinge is fixed within the groove.

[0037] The third hinge, one end of which is pivotally connected to the second hinge via a third pivot, and the other end of which is pivotally connected to the wrist strap via a fourth pivot;

[0038] When the wrist strap switches from the open state to the closed state, the third hinge of the two hinges rotates in a direction away from each other;

[0039] A torsion spring, wherein the first torsion arm of the torsion spring is fixed relative to the second hinge, and the second torsion arm of the torsion spring is fixed relative to the third hinge. 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 strap groove, thereby causing the hand strap to flatten and close into the strap groove to form the closed state.

[0040] In one embodiment, the back of the housing is further provided with a support groove, and a support that can rotate between a first position and a second position is provided in the support groove.

[0041] When the bracket is in the first position, the bracket is housed in the bracket slot. When the bracket is rotated to the second position, the bracket forms a predetermined angle with the housing and can support the housing on an external bearing surface to form a predetermined viewing angle.

[0042] In one embodiment, the bracket is a U-shaped bracket, and the groove includes a first groove and a second groove connected in its length direction;

[0043] The width of the second groove is greater than the width of the first groove. When the hand strap is flattened and folded into the groove to form the folded state, a U-shaped support groove is defined between the hand strap and the peripheral wall of the second groove.

[0044] In one embodiment, a stop surface is formed at the connection between the first and second groove segments;

[0045] When the bracket is rotated 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.

[0046] In one embodiment, the housing is provided with a magnetic element, which is located near the end of the second groove and is used to attract and fix the U-shaped bracket when the U-shaped frame rotates and retracts into the bracket groove.

[0047] In one embodiment, the groove extends from the back of the housing to the receiving groove, and a cover plate for closing the groove is embedded on the bottom surface of the receiving groove, and the hinge portion is formed on the cover plate.

[0048] The technical solution of this application, by setting a groove on the back of the casing and using a hinge to connect both ends of the flexible wrist strap into the groove, achieves a fully retractable wrist strap within the groove, avoiding the problem of traditional wrist straps protruding outwards, making the overall structure of the phone case more concise and aesthetically pleasing. Furthermore, because the wrist strap is fully retracted into the groove and does not protrude outwards, the phone case can be placed stably on a wireless charging pad, allowing wireless charging to be used even with the phone case on, without removing the case, thus improving ease of use. When the wrist strap function is needed, it can be easily lifted from the groove, creating a finger hole between the wrist strap and the casing, ensuring stability during use.

[0064] With the widespread use of smartphones in people's daily lives, phone cases have become an essential accessory for protecting their phones. By covering the outside of the phone, a phone case effectively prevents scratches from everyday use and also acts as a cushioning device in the event of a drop, reducing the risk of damage.

[0065] To further enhance the safety and convenience of mobile phone use, some phone cases feature a ring or strap on the back. During use, fingers can be inserted into the ring or strap to prevent the phone from falling, thus improving safety and convenience.

[0066] However, for phone cases with straps, the strap is directly located on the back of the case. One end of the strap is fixed to the case with rivets, while the other end slides through a hole to connect with a rivet on the case, allowing the strap to be pulled open and slipped over the fingers. This structure, with the strap and rivets protruding from the back of the case, presents several problems. First, the structure is not clean, leading to a poor user experience. For example, when putting the phone in a pocket, the protruding strap and rivets may get stuck against the pocket edge. Second, when holding the phone with one hand, the palm inevitably comes into contact with the protruding strap and rivets, causing a foreign object sensation that affects the user experience and reduces grip comfort. Third, because the 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 can easily detach from the rivet, resulting in poor connection reliability.

[0067] Based on the above considerations, this application proposes a mobile phone case.

[0068] Referring to Figures 1 to 8, the mobile phone case provided according to the embodiments of this application 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 electronic equipment. The size and shape of the receiving slot H101 are adapted to the electronic equipment to be protected, ensuring that the electronic equipment can be securely installed inside the protective housing. The back of the housing 10 has a groove H102 that extends in a predetermined direction, such as along the length or width of the housing 10. This groove H102 is used to accommodate a wrist strap 20.

[0070] The two ends of the wrist strap 20 are respectively connected to the groove H102. The wrist strap 20 is flattened in the length direction of the groove H102 and housed in the groove H102 to form a closed state.

[0071] When the hand strap 20 moves away from the housing 10 under the action of an external force, the hand strap 20 can switch from the closed state to the open state. In the open state, the hand strap 20 bends and forms a finger hole between itself and the back of the housing 10, through which the user's fingers can pass.

[0072] In other words, when not in use, the wrist strap 20 can be completely flattened and stored in the slot H102, forming a folded state, keeping the back of the phone case flat. In actual use, the user can apply external force to pull the wrist strap 20 out of the slot H102. At this time, the wrist strap 20 will switch from the folded state to the open state by rotating the hinge 11. In the open state, the flexible wrist strap 20 will naturally form an arc shape, creating a finger hole between itself and the back of the case 10, allowing the user to pass their fingers through, thus providing stable grip support.

[0073] According to the embodiments of this application, the phone case provides a groove H102 on the back of the case 10, and connects both ends of the flexible wrist strap 20 to the groove H102. This allows the wrist strap 20 to be completely retracted into the groove H102, avoiding the problem of traditional shoulder straps protruding outwards, making the overall structure of the phone case simpler and more aesthetically pleasing. Furthermore, since the wrist strap 20 is completely retracted into the groove H102 and does not protrude outwards, the phone case can be placed stably on a wireless charging pad, allowing wireless charging to be used even when the phone is wearing the case, without needing to remove the case, thus improving ease of use. When the wrist strap 20 is needed, it can be easily lifted from the groove H102, creating an arc-shaped space suitable for fingers to pass through. This ensures the stability of the wrist strap 20 during use and solves the problems of foreign object sensation and jamming caused by protruding shoulder straps and rivets in traditional designs.

[0074] In some implementations, the wristband 20 is made of a flexible material that ensures both comfort during use and good bendability. For example, the flexible material can be made of silicone, leather, or other materials.

[0075] Referring to Figures 3 and 4, in some embodiments of this application, the phone case further includes a hinge 11, with both ends of the hinge 11 connected to the end of the wrist strap 20 and the housing 10, respectively. The use of a hinge 11 replaces the traditional sliding hole and rivet structure, significantly improving the reliability of the wrist strap 20 connection and avoiding the risk of detachment caused by the expansion of the sliding hole. The phone case of this application, while ensuring functionality, greatly enhances the user experience and safety.

[0076] Referring to Figures 3 and 4, in some embodiments of this application, the hinge 11 is a torsion spring hinge 11. When the external force on the hand strap 20 is removed, under the torsion of the torsion spring hinge 11, the hand strap 20 is straightened and flattened in the length direction of the groove H102 to return to the closed state.

[0077] In this embodiment, the hinge 11 is a torsion spring hinge 11. This hinge 11 structure not only has the rotation function of a normal hinge 11, but also has the function of automatically resetting when the hand strap 20 is released, provided by the torsion spring 112.

[0078] 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 to return to the initial position. This causes the hand strap 20 to be automatically straightened and flattened along the length of the groove H102, and finally returned to the folded state completely stored in the groove H102.

[0079] The use of a torsion spring hinge 11 enables the automatic retraction of the wristband 20, greatly improving ease of use. After using the wristband 20, users do not need to manually press it back into the groove H102; simply releasing the wristband 20 allows it to automatically return to the retracted state under the force of the torsion spring 112, resulting in a smoother and more natural user experience. Furthermore, the torsion spring 112 provides moderate damping force, ensuring that the wristband 20 remains taut and securely attached to the fingers when open, thus maintaining a more stable fit and preventing wobbling or accidental slippage. This damping characteristic ensures stability during use without affecting the normal opening and closing of the wristband 20. Moreover, the torsion spring 112 ensures that the wristband 20 remains firmly attached to the bottom of the groove H102 when retracted, preventing wobbling or lifting within the groove and maintaining the product's flatness. This secure fit also prevents the wristband 20 from scratching or snagging with other items.

[0080] Referring to Figures 3 to 6, in one embodiment of this application, the hinge 11 includes a first hinge 111. One end of the first hinge 111 is pivotally connected to the groove H102 via a first pivot, and the other end of the first hinge 111 is pivotally connected to the hand strap 20 via a second pivot. This double pivot design allows the hand strap 20 to move with greater freedom, enabling smoother and more natural opening and closing.

[0081] When the hand strap 20 switches from the open state to the closed state, the first hinges 111 of the two hinges 11 rotate in a direction away from each other. Since the two first hinges 111 are respectively located at both ends of the hand strap 20, when the two first hinges 111 rotate in a direction away from each other, they can drive the two ends of the hand strap 20 to move in a direction away from each other, thereby straightening and flattening the hand strap 20 along the length of the groove H102.

[0082] For example, in the example shown in Figure 6, during the use of the hand strap 20, when the user pulls the hand strap 20 upwards, the hand strap 20 causes the first hinges 111 at both ends to rotate upwards. At this time, the two first hinges 111 move towards each other, thus providing conditions for the bending of the hand strap 20, allowing it to bend and form finger holes when pulled up. When the user releases the pulling force on the hand strap 20 and switches the hand strap 20 from the open state to the closed state, the first hinges 111 in the two hinges 11 rotate downwards, that is, the two first hinges 111 rotate away from each other, thus causing the two ends of the hand strap 20 to move away from each other, so that it can be straightened, flattened, and evenly and smoothly stored in the strap groove H102, avoiding wrinkles or deformation during the closing process.

[0083] 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 closing process, preventing wrinkles or deformation and improving the flatness and aesthetics of the closed state.

[0084] Referring to Figures 3 and 4, in one embodiment of this application, the hinge 11 further includes a torsion spring 112. The first torsion arm of the torsion spring 112 is fixed relative to the first hinge 111, and the second torsion arm of the torsion spring 112 is fixed relative to the housing 10. When the external force on the hand strap 20 is removed, the torque of the torsion spring 112 causes the first hinge 111 to rotate into the groove H102, and drives the hand strap 20 to flatten and close into the groove H102 to form the closed state.

[0085] When the wrist strap 20 is in the open state, the torsion spring 112 is under torsional deformation and stores elastic potential energy. When the user removes the external force applied to the wrist strap 20, the torsion spring 112 releases the stored potential energy, generating a torque that causes the first hinge 111 to rotate into the groove H102. Under the action of this torque, the first hinge 111 pulls the end of the wrist strap 20 towards the end of the groove H102, ultimately causing the wrist strap 20 to flatten out along the length of the groove H102 and be completely retracted into the groove H102, forming a closed state.

[0086] As described above, the design of the torsion spring 112 enables the automatic retraction of the hand strap 20. Through the conversion of the elastic potential energy of the torsion spring 112, the hand strap 20 can automatically return to the retracted position without manual operation by the user. This automated retraction method greatly improves the ease of use of the product, making its operation simpler and more convenient.

[0087] Referring to Figures 3 and 4, in one embodiment of this application, a hinge portion 1011 is provided in the groove H102, the hinge portion 1011 having two pivot portions 1011a opposite to each other in the width direction of the groove H102.

[0088] One end of the first hinge 111 is located between the two pivot portions 1011a, and one end of the first hinge 111 has 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 pivot portion 1011a.

[0089] In this embodiment, a stable hinge 11 rotation support structure is formed by providing a hinge portion 1011 with two opposing pivot portions 1011a within the groove H102, and placing one end of the first hinge 111 between the two pivot portions 1011a. A notch at the end of the first hinge 111 provides installation space for the torsion spring 112, allowing the torsion spring 112 to be compactly installed inside the notch. The first pivot shaft passes through the torsion spring 112 and connects the first hinge 111 to the pivot portion 1011a, achieving integrated assembly of the torsion spring 112, the first hinge 111, and the pivot portion 1011a. This results in a more compact and lightweight structure with more stable and reliable pivoting.

[0090] It should be understood that in this embodiment, the hinge 11 only requires one hinge (i.e., the first hinge 111), which is directly pivotally connected to the hinge portion 1011 of the housing 10. That is, the pivotal connection between the end of the wrist strap 20 and the housing 10 is achieved by using one hinge and the torsion spring 112. This hinge 11 structure implemented by a single hinge can significantly simplify the structure. In scenarios where the thickness of the phone case is small, a pivotal connection can be achieved without increasing the thickness of the phone case as much as possible, and the reliability of its pivotal connection is also guaranteed.

[0091] In another embodiment of this application, the hinge 11 includes a second hinge and a third hinge, with the second hinge fixed within the groove H102. One end of the third hinge is pivotally connected to the second hinge via a third pivot, and the other end of the third hinge is pivotally connected to the hand strap 20 via a fourth pivot.

[0092] When the hand strap 20 switches from the open state to the closed state, the third hinge of the two hinges 11 rotates in a direction away from each other.

[0093] This embodiment employs a double-hinged structure design. Through the cooperation of the second and third hinges, the second hinge is fixed within the groove H102 as a reference component, while the third hinge forms a rotation node with the second hinge via a third pivot. Simultaneously, the third hinge is connected to the hand strap 20 via a fourth pivot, also forming a rotation node. This double-hinged design achieves the same pivotal connection while ensuring a flexible movement trajectory for the third hinge.

[0094] Optionally, the second hinge can be fixedly connected to the housing 10, thus eliminating the need for a pivoting connection structure on the housing 10. The second hinge can simply be fixed in the groove H102, simplifying the structure of the housing 10. Alternatively, the end of the second hinge furthest from the third hinge can be rotatably connected to the housing 10, allowing both the second and third hinges to unfold outwards.

[0095] In some embodiments, hinge 11 further includes a torsion spring 112. The first torsion arm of the torsion spring 112 is fixed relative to the second hinge, and the second torsion arm of the torsion spring 112 is fixed relative to the third hinge. When the external force on the handle 20 is removed, the torque of the torsion spring 112 causes the third hinge to rotate into the groove H102, thereby flattening and closing the handle 20 within the groove H102 to form the closed state. Furthermore, the cooperative design of the torsion spring 112 with the second and third hinges makes the pivoting structure more reliable and stable.

[0096] In some embodiments, the end of the second hinge furthest from the third hinge is rotatably connected to the housing 10. In this case, a torsion spring can be provided between the second hinge and the housing 10. When the external force on the hand strap 20 is removed, the torque of the torsion spring between the second hinge and the housing 10 causes the second hinge to rotate into the groove H102, thereby driving the third hinge and the hand strap 20 to move into the groove. At the same time, the torque of the torsion spring between the second hinge and the third hinge causes the third hinge to rotate into the groove H102, thereby causing the hand strap 20 to flatten and fold into the groove H102 to form the folded state.

[0097] Referring to Figures 2 and 7, in some embodiments of this application, the phone case further includes a bracket 12, which is rotatably connected to the housing 10 and has a first position and a second position. When the bracket 12 is in the first position, it is folded into the housing 10. When the bracket 12 is in the second position, it is set at an angle to the housing 10 and can support the housing 10 on an external bearing surface.

[0098] This embodiment achieves the support function of the phone case by configuring a rotatable bracket 12 on the back of the housing 10. The bracket 12 can switch between a first position and a second position. The first position is the storage position, in which the bracket 12 is completely stored in the bracket groove H103 of the housing 10, maintaining the flatness of the back of the phone case. The second position is the support position, in which the bracket 12 rotates out and forms a predetermined angle with the housing 10, which can stably support the phone and place it on a table or other support surface at a suitable angle.

[0099] Referring to Figures 2 to 4 and Figure 7, in some embodiments of this application, the back of the housing 10 is further provided with a support groove H103, and a support 12 that can rotate between a first position and a second position is provided in the support groove H103.

[0100] When the bracket 12 is in the first position, the bracket 12 is housed in the bracket groove H103. When the bracket 12 is rotated to the second position, the bracket 12 forms a predetermined angle with the housing 10 and can support the housing 10 on the external bearing surface to form a predetermined angle.

[0101] This embodiment achieves the support function of the phone case by providing a support groove H103 on the back of the housing 10 and arranging a rotatable support 12 therein. The support 12 can switch between a first position and a second position. The first position is the storage position, in which the support 12 is completely stored in the support groove H103, maintaining the flatness of the back of the phone case. The second position is the support position, in which the support 12 rotates out from the support groove H103 and forms a predetermined angle with the housing 10, which can stably support the phone and place it on a table or other support surface at a suitable angle.

[0102] The design of the stand 12 and stand slot H103 allows the stand 12 to be completely retracted, preventing it from being exposed and affecting phone case storage and user experience. When not in use, the stand 12 can be folded into the stand slot H103. In use, simply rotating the stand 12 to the second position creates a predetermined angle, ensuring phone stability and providing a comfortable viewing experience. Furthermore, this rotatable stand 12 allows users to quickly switch phone placement positions, improving product usability and meeting diverse user needs.

[0103] Referring to Figures 3 and 4, in one embodiment of this application, the bracket 12 is a U-shaped bracket, and the groove H102 includes a first groove H102a and a second groove H102b connected in its length direction.

[0104] The width of the second groove H102b is greater than the width of the first groove H102a. When the hand strap 20 is flattened and folded into the groove H102 to form the folded state, a U-shaped support groove H103 is defined between the hand strap 20 and the peripheral wall of the second groove H102b.

[0105] In other words, in this embodiment, the groove H102 is divided into two segments along its length: a first segment H102a and a second segment H102b, wherein the width of the second segment H102b is greater than the width of the first segment H102a. This width difference causes a U-shaped space to be naturally formed between the hand strap 20 and the peripheral wall of the second segment H102b when the hand strap 20 is in the retracted state. This space is used as the support groove H103 of the U-shaped frame.

[0106] By structurally integrating the support groove H103 with the groove H102, on the one hand, the need for a separate support groove H103 is avoided, thereby reducing the number of grooves on the back of the housing 10, making the product structure simpler and the appearance more aesthetically pleasing. Furthermore, it reduces the complexity of mold processing, which is beneficial for improving production efficiency and reducing manufacturing costs. On the other hand, utilizing the space between the hand strap 20 and the peripheral wall of the second groove H102b as the support groove H103 fully utilizes the existing structural space and improves space utilization. When the hand strap 20 is in the retracted state, the naturally formed U-shaped space due to the wider second groove H102b perfectly accommodates the U-shaped frame, allowing the support 12 to be completely hidden and maintaining the flatness of the product's back side.

[0107] For example, the two ends of the U-shaped frame are bent outward to form a pivot portion, and shaft holes are provided on both sides of the support groove H103. The pivot portions at both ends of the U-shaped frame are pivotally engaged with the shaft holes on both sides of the support groove H103, so that the pivotal connection between the U-shaped frame and the housing 10 can be realized.

[0108] Preferably, as shown in Figure 8, a damping sleeve 121 is fitted on the rotating shaft. The damping sleeve 121 can be made of soft rubber material, such as rubber or silicone. When the rotating shaft is engaged with the shaft hole, the damping sleeve 121 can increase the rotational damping between the shaft and the shaft hole, ensuring that the U-shaped frame is not easy to rotate at will, thus improving the user experience.

[0109] In some embodiments of this application, the housing 10 is provided with a magnetic element 102, which is located near the end of the second groove H102b, and is used to attract and fix the U-shaped frame when it rotates and retracts into the support groove H103. The magnetic element 102 can be a permanent magnet. In this way, when the U-shaped frame rotates and retracts into the support groove H103, the U-shaped frame can be reliably and stably held in the support groove H103 under the attraction of the magnetic element 102, preventing the U-shaped frame from easily falling out of the support groove H103.

[0110] It is understood that in other embodiments, in order to prevent the U-shaped frame from easily falling off the support groove H103, other methods may be used to replace or combine the magnetic component 102, such as setting a buckle or other structure on the side wall of the support groove H103.

[0111] Referring to FIG4, in one embodiment of this application, a stop surface S10 is formed at the connection between 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, so that the bracket 12 stops at the second position and forms the predetermined angle with the housing 10.

[0112] In other words, because 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. The position where the U-shaped frame is pivotally connected to the housing 10 is close to the stop surface S10. Thus, when the bracket 12 rotates from the first position to the second position, the bracket 12 will abut against the stop surface S10, thereby naturally forming a mechanical limit, so that the bracket 12 is stably stopped in the second position and maintains a predetermined angle with the housing 10.

[0113] In this embodiment, a stop surface S10 is formed at the connection between the first groove H102a and the second groove H102b. This stop surface S10 provides a simple and reliable positioning structure for the bracket 12. This design eliminates the need for additional positioning parts, directly utilizing the geometric features of the groove H102 to achieve the positioning of the bracket 12. This saves on parts costs, simplifies the product structure, and improves product reliability.

[0114] Referring to Figures 1 to 4, in one embodiment of this application, a groove H102 extends from the back of the housing 10 to the receiving groove H101. A cover plate 101 for closing the groove H102 is embedded in the bottom surface of the receiving groove H101, and a hinge portion 1011 is formed on the cover plate 101. Exemplarily, the cover plate 101 can be fixed to the housing 10 by snap-fit, screws, adhesive, or any other fixable method.

[0115] In this embodiment, the groove H102 is set as a through structure, and the groove H102 is closed by the cover plate 101, which can facilitate the processing of the housing 10 structure. Since the cover plate 101 needs to be provided with a hinge part 1011 and other structures, the cover plate 101 is processed separately, which makes the processing technology simpler.

[0116] The above description is merely an exemplary embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
