Description

Technical Field

[0001] This utility model belongs to the technical field of electronic device protective housings, and specifically relates to a protective housing. Background Technology

[0002] With the widespread adoption of smartphones in daily life and work, users are increasingly using their phones in diverse scenarios. Beyond basic calls and messaging, the frequency of using phones for video playback, video conferencing, and live streaming has significantly increased. Driven by this demand, phone cases are no longer limited to basic drop and scratch protection. Multifunctional cases have become a key trend in the industry, with the integrated "case + stand" design being one of the mainstream designs due to its ability to effectively improve ease of use.

[0003] Existing phone cases with integrated stand functionality typically have a recess or pre-drilled mounting position on the back of the case (the side of the phone opposite the screen), connected to a foldable stand via a hinge. In use, the user flips the stand from its folded-back position to a preset angle (e.g., a support angle of 30°-60°), using the stand's contact with a flat surface (e.g., a table) to keep the phone tilted upright, satisfying needs such as video viewing and hands-free operation, thus integrating the functions of a protective case and a stand.

[0004] However, current methods for positioning folding phone cases generally rely on rotational damping between the case and the pivot. Specifically, existing designs typically use an interference fit at the connection between the pivot and the case, or incorporate damping materials like rubber or silicone on the contact surface. Rotational damping is achieved through friction between the components. When the case is flipped to the target angle, the damping force counteracts the phone's gravitational torque, keeping the case in that position. However, in long-term use, repeated flipping causes wear on the damping components due to continuous friction (e.g., wear on interference-fit metal parts leading to increased clearance, or aging and detachment of the damping material). This results in a gradual decrease or even failure of the rotational damping force. When the damping force is insufficient to maintain positioning, the case may experience angle shifts or slippage under the phone's weight, severely impacting reliability and user experience. This is a critical technical defect that current phone cases with folding stands urgently need to address. Utility Model Content

[0010] Optionally, the first mating surface has a strip-shaped hole, which is spaced apart from the edge of the first mating surface to form a spring piece between the strip-shaped hole and the edge of the first mating surface, and the positioning groove is located on the spring piece.

[0011] Optionally, the spring piece is provided with an opening in the middle of the positioning groove, and the opening divides the spring piece into two suspended spring pieces.

[0012] Optionally, the width of the free end of the suspended spring is greater than the width of the fixed end of the suspended spring; and / or, The fixed end of the suspended spring is provided with a hollow hole.

[0013] Optionally, the housing has a through hole, and the fixing member and the rotating seat are embedded in the through hole, and the fixing member is fixedly connected to the through hole, and the rotating seat is rotatably disposed relative to the fixing member; The fixing member is an annular structure with a central hole. The rotating seat includes a first cover and a second cover. The fixing member is located between the first cover and the second cover. The first cover and the second cover are connected to each other through the central hole of the fixing member. The bracket is rotatably connected to the first cover. The positioning groove is provided on the side of the second cover facing the fixing member. The outer diameters of both the first cover and the second cover are larger than the inner diameter of the central hole of the fastener; The rotating seat also includes a first hinge plate and a second hinge plate, which are hinged to each other. The first hinge plate is connected to the bracket, and the second hinge plate is located between the first cover and the second cover, and is connected to the first cover and the second cover.

[0014] Optionally, the through hole is a stepped hole, the fastener is embedded in the stepped surface of the stepped hole, the inner wall of the stepped hole is provided with multiple limiting grooves, the fastener is provided with multiple positioning flanges, and the multiple positioning flanges are embedded in the multiple limiting grooves.

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] See Figures 1-8 As shown, one embodiment of this utility model provides a protective shell, including a shell 1, a bracket 2, a rotating base 3, and a fixing member 4. The fixing member 4 is disposed on the shell 1. The bracket 2 is rotatably disposed relative to the rotating base 3. The rotating base 3 and the fixing member 4 are stacked and fitted together, and the rotating base 3 is rotatably disposed relative to the fixing member 4. The surface of the rotating base 3 that is fitted with the fixing member 4 is a first fitting surface 323, and the first fitting surface 323 is provided with a positioning groove 321. The surface of the fixing member 4 that is fitted with the rotating base 3 is a second fitting surface 43, and the second fitting surface 43 is provided with a positioning protrusion 41 corresponding to the position of the positioning groove 321. When the rotating base 3 rotates until the positioning protrusion 41 is embedded in the positioning groove 321, the rotating base 3 and the fixing member 4 are in a temporary positioning state.

[0023] In the protective shell, a mechanical locking positioning mechanism is constructed by layering and bonding the rotating base 3 and the fixing member 4, with positioning grooves 321 and positioning protrusions 41 respectively provided on their bonding surfaces. When the rotating base 3 rotates to the target position, the positioning protrusion 41 embeds into the positioning groove 321 to form a temporary position. This positioning method does not rely on frictional damping between components, completely avoiding the problem of damping force reduction or failure caused by long-term friction and wear, and significantly improving the stability and service life of the bracket 2's angle positioning. At the same time, the positioning feedback of the mechanical locking structure is clearer, and the operator can accurately judge the positioning status through the tactile feel of the protrusion and groove, making the operation experience more intuitive. In addition, the layered bonding design of the rotating base 3 and the fixing member 4 achieves reliable positioning without excessively increasing the overall thickness of the protective shell, taking into account both structural compactness and portability.

[0024] like Figure 2 As shown, in one embodiment, the housing 1 is provided with a receiving groove 13 for accommodating the bracket 2. The rotating seat 3 and the fixing member 4 are located on the side of the receiving groove 13. The rotation axis of the rotating seat 3 and the fixing member 4 is perpendicular to the surface of the housing 1. The rotation axis of the bracket 2 and the rotating seat 3 is parallel to the surface of the housing 1. When the rotating seat 3 rotates to a preset position, the bracket 2 can rotate relative to the rotating seat 3 to be inserted into the receiving groove 13 or disengaged from the receiving groove 13. At the preset position, at least one of the positioning protrusions 41 is embedded in at least one of the positioning grooves 321.

[0025] The shape of the receiving groove 13 is adapted to the shape of the bracket 2.

[0026] On the one hand, the receiving groove 13 on the housing 1 can accommodate the bracket 2, avoiding scratches or accidental contact caused by the bracket 2 being exposed, ensuring the flatness of the surface of the housing 1, and improving the overall aesthetics and carrying safety of the protective case; on the other hand, by clarifying that the rotation axis of the rotating seat 3 and the fixing part 4 is perpendicular to the surface of the housing 1, and the rotation axis of the bracket 2 and the rotating seat 3 is parallel to the surface of the housing 1, the flipping action of the bracket 2 (embedding / removing from the receiving groove 13) and the angle adjustment action of the rotating seat 3 are independent and coordinated with each other. The operator can first adjust the rotating seat 3 to the preset position (at this time, the positioning protrusion 41 and the positioning groove 321 are engaged to achieve positioning), and then flip the bracket 2 to complete the support or storage, making the operation logic clearer. Meanwhile, the design that "at least one of the positioning protrusions 41 is embedded in at least one of the positioning grooves 321 at the preset position" can play an auxiliary role in storage and positioning. When the bracket 2 needs to be stored, the rotating seat 3 is rotated to the preset position. At this time, the positioning protrusion 41 is embedded in the positioning groove 321, which can give the operator a feeling of rotating it into place. At this time, the flipped bracket 2 can be stored in the receiving groove 13, avoiding the positional deviation between the flipped bracket 2 and the receiving groove 13 caused by the rotation angle deviation of the rotating seat 3, making it difficult to embed into the receiving groove 13.

[0027] like Figure 7 As shown, in one embodiment, there are four positioning protrusions 41 arranged in a ring array on the fixing member 4, and two positioning grooves 321 located on a radial straight line of the rotating seat 3. The positioning protrusions 41 are hemispherical structures.

[0028] The positioning protrusions 41 are designed as multiple protrusions arranged in a ring array and adopt a hemispherical structure, which has two advantages: First, the multiple positioning protrusions 41 in the ring array cooperate with the corresponding positioning grooves 321 to realize multi-position positioning of the rotating seat 3, corresponding to different positioning needs. For example, in addition to the preset position positioning used for the storage of the bracket 2, it also allows the operator to flexibly select the support angle according to the usage scenario, making it more adaptable. Specifically, in this embodiment, there are 4 positioning protrusions 41 arranged in a cross shape, and there are 2 positioning grooves 321 arranged linearly. When 2 positioning protrusions 41 are embedded in 2 positioning grooves 321, the other 2 positioning protrusions 41 can play a role in balancing support, improving the stability of the rotating seat 3. Secondly, the hemispherical raised arc surface design makes the engagement and disengagement of the positioning protrusion and positioning groove smoother. This avoids the problems of sharp structure jamming or wear, and the guiding effect of the arc contact surface reduces the operating resistance when the operator rotates the rotating seat 3. It takes into account both positioning stability and operation convenience, and is especially suitable for the use of frequent angle adjustment needs.

[0029] like Figure 9 and Figure 10 As shown, in one embodiment, protrusions 326 are formed on both sides of the positioning groove 321, the protrusions 326 protrude from the first mating surface 323, the positioning groove 321 is a recess formed between the two protrusions 326, and the first mating surface 323, the protrusions 326 and the positioning groove 321 are smoothly transitioned.

[0030] By forming protrusions 326 on both sides of the positioning groove 321, a small damping feel can be provided before the positioning protrusion 41 is about to rotate into the positioning groove 321, thereby giving the operator a better sense of operation when the rotating seat 3 is rotated to the preset position, avoiding the problem of under-rotation or over-rotation, and achieving more accurate positioning.

[0031] In one embodiment, the first mating surface 323 has a strip-shaped hole 324, which is spaced apart from the edge of the first mating surface 323, so that a spring piece portion 325 is formed between the strip-shaped hole 324 and the edge of the first mating surface, and the positioning groove 321 is located on the spring piece portion 325.

[0032] The formation of the spring piece 325 by the strip hole 324 helps to improve the elastic deformation capability of the location of the positioning groove 321, thereby avoiding plastic deformation during rotation and ensuring the durability and stability of the positioning method.

[0033] like Figure 9 As shown, in one embodiment, the strip hole 324 is an arc-shaped hole.

[0034] like Figure 11 As shown, in one embodiment, the strip hole 324 is a straight hole.

[0035] In one embodiment, the spring piece portion 325 is provided with an opening 3252 in the middle of the positioning recess 321 groove, and the opening 3252 divides the spring piece portion 325 into two suspended spring pieces 3251. One end of the suspended spring piece 3251 is a fixed end 3254, and the other end of the suspended spring piece 3251 is a free end 3253, and the free ends 3253 of the two suspended spring pieces 3251 are spaced apart and opposite to each other.

[0036] The opening 3252 is provided on the spring piece 325, which allows the suspended spring piece 3251 to be fixed at one end and form a free end 3253 at the other end, so that it can undergo better elastic deformation under external force.

[0037] like Figure 11As shown, in one embodiment, the width of the free end 3253 of the suspended spring 3251 is greater than the width of the fixed end 3254 of the suspended spring 3251.

[0038] Due to the specific structure of the suspended spring 3251, it undergoes elastic deformation at the fixed end 3254. By setting the width of the free end 3253 of the suspended spring 3251 to be greater than the width of the fixed end 3254 of the suspended spring 3251, it is beneficial to improve the elastic deformation capability of the fixed end 3254.

[0039] In one embodiment, the fixed end 3254 of the suspended spring 3251 is provided with a hollow hole 327.

[0040] Similar to the width limiting function of the free end 3253, by opening a hollow hole 327 in the fixed end 3254, the cross-section of the fixed end 3254 can be reduced, which also improves the elasticity.

[0041] like Figure 2 and Figure 3 As shown, in one embodiment, the housing 1 has a through hole 14, and the fixing member 4 and the rotating seat 3 are embedded in the through hole 14. The fixing member 4 is fixedly connected to the through hole 14, and the rotating seat 3 is rotatably disposed relative to the fixing member 4.

[0042] By creating a through hole 14 in the housing 1 and embedding the fixing member 4 and the rotating base 3 into the through hole 14, and fixing the fixing member 4 to the through hole 14, the "rotating base 3 - fixing member 4" assembly and the housing 1 are integrated. This embedded structure reduces the external space occupied by the components in the housing 1, making the back of the protective case flatter and avoiding protruding structures that may affect the hand feel or cause instability. At the same time, the fixed connection between the fixing member 4 and the through hole 14 restricts the displacement or wobbling of the fixing member 4, ensuring the axial stability of the rotating base 3 when rotating relative to the fixing member 4, further reducing positioning deviation, and improving the overall assembly accuracy and reliability from the structural foundation. It is especially suitable for the design requirements of thin and light mobile phone protective cases.

[0043] like Figure 6 and Figure 8 As shown, in one embodiment, the fixing member 4 is an annular structure with a central hole, the rotating seat 3 includes a first cover 31 and a second cover 32, the fixing member 4 is located between the first cover 31 and the second cover 32, the first cover 31 and the second cover 32 are connected to each other through the central hole of the fixing member 4, the bracket 2 is rotatably connected to the first cover 31, and the positioning groove 321 is provided on the side of the second cover 32 facing the fixing member 4.

[0044] The first cover 31, the fixing member 4, and the second cover 32 form a sandwich assembly structure. On the one hand, the clamping action of the first cover 31 and the second cover 32 stabilizes and limits the fixing member 4, preventing axial loosening between the fixing member 4 and the rotating seat 3, and ensuring that the positioning protrusion 41 and the positioning groove 321 always remain in contact, thus improving positioning stability. On the other hand, the bracket 2 is rotatably connected to the first cover 31, and the positioning groove 321 is located on the side of the second cover 32 facing the fixing member 4, so that the flipping action of the bracket 2 and the angle adjustment action of the rotating seat 3 are spatially separated, avoiding interference between the two movements. At the same time, it simplifies the internal structural layout of the component, reduces assembly complexity, and facilitates mass production.

[0045] In one embodiment, the first cover 31, the fixing member 4 and the second cover 32 are all sheet-like structures, which have a small axial thickness after being stacked, and are suitable for embedded installation on the housing 1, so as to avoid protruding from the housing 1 and affecting the surface flatness.

[0046] In one embodiment, the outer diameters of the first cover 31 and the second cover 32 are both larger than the inner diameter of the intermediate hole of the fixing member 4.

[0047] This design creates an axial limiting structure: the edges of the first cover 31 and the second cover 32 can shield and limit the fixing member 4, preventing the fixing member 4 from coming out of the central hole between the first cover 31 and the second cover 32, thus avoiding the failure of the positioning function due to the fixing member 4 falling off. Compared with methods that rely on adhesive bonding or additional fasteners, this mechanical limiting structure is more reliable and requires no additional assembly steps. It simplifies the manufacturing process and improves the component's drop and impact resistance, ensuring that the "rotating seat 3 - fixing member 4" assembly can still maintain a stable assembly state when the protective shell is accidentally dropped or collided.

[0048] In one embodiment, the rotating seat 3 further includes a first hinge plate 33 and a second hinge plate 34, the first hinge plate 33 and the second hinge plate 34 are hinged to each other, the first hinge plate 33 is connected to the bracket 2, the second hinge plate 34 is located between the first cover 31 and the second cover 32, and the second hinge plate 34 is connected to the first cover 31 and the second cover 32.

[0049] The second hinge plate 34 has a plurality of first mounting holes 341. The first cover 31 has a plurality of connecting posts 311 on the side facing the second cover 32. The second cover plate has a plurality of second mounting holes 322. Some of the connecting posts 311 pass through the first mounting holes 341 and the second mounting holes 322, and some of the connecting posts 311 pass through the second mounting holes 322. The connecting posts 311 are connected to the mounting holes by welding, riveting or screw connection.

[0050] The first hinge plate 33 and the second hinge plate 34 are connected to each other by a hinge 35. The first cover 31 is provided with a notch 312 to avoid the hinge 35, so that the hinge 35 is embedded in the first cover 31 and the hinge 35 is not protruding from the first cover 31, causing the surface of the shell 1 to be uneven.

[0051] Specifically, the first cover 31 is a semi-circular sheet structure with a notch 312, the fixing member 4 is an annular sheet structure, and the second cover 32 is a circular sheet structure.

[0052] like Figure 3 As shown, in one embodiment, the through hole 14 is a stepped hole, the fixing member 4 is embedded in the stepped surface of the stepped hole, the inner wall of the stepped hole is provided with a plurality of limiting grooves 15, the fixing member 4 is provided with a plurality of positioning flanges 42, and the plurality of positioning flanges 42 are embedded in the plurality of limiting grooves 15.

[0053] The positioning flange 42 and the fixing member 4 are an integral structure.

[0054] The through hole 14 is designed as a stepped hole, with the fastener 4 embedded in the stepped surface for axial positioning. Simultaneously, the limiting groove 15 on the inner wall of the stepped hole engages with the positioning flange 42 of the fastener 4, achieving circumferential positioning of the fastener 4. This design provides double positioning of the fastener 4 in both axial and circumferential dimensions, completely eliminating axial movement or circumferential rotation of the fastener 4 during use. This ensures the relative position stability of the fastener 4 and the rotating seat 3, preventing misalignment of the positioning protrusion 41 and the groove due to displacement of the fastener 4, thus affecting the positioning function. Compared to single axial or circumferential fixing, the double-limiting structure offers higher assembly precision, making it particularly suitable for scenarios involving frequent and prolonged rotation of the rotating seat 3, effectively maintaining the stability of the positioning structure.

[0055] like Figure 6 As shown, in one embodiment, a protective plate 5 is also included. The protective plate 5 is located on the side of the second cover 32 away from the first cover 31, and the protective plate 5 closes the through hole 14 to isolate the second cover 32 from the internal cavity of the housing 1, so as to avoid interference between the second cover 32 and the surface of the electronic product inside the housing 1 during rotation.

[0056] like Figure 4 As shown, in one embodiment, the bracket 2 includes a magnetic suction member 23, a first arc-shaped portion 25, a second arc-shaped portion 21, and a rotating connecting portion 22. The first arc-shaped portion 25 is connected to the rotating connecting portion 22. The two ends of the first arc-shaped portion 25 and the two ends of the second arc-shaped portion 21 are connected to each other to form a gourd-like structure. The rotating connecting portion 22 is rotatably disposed with the rotating seat 3. The first arc-shaped portion 25 is used to avoid the mobile phone logo. An arc-shaped groove 211 is provided in the second arc-shaped portion 21. The magnetic suction member 23 is an arc-shaped sheet and is embedded in the arc-shaped groove 211.

[0057] By setting the first arc-shaped part 25, the back logo of the phone can be avoided, thus preventing the bracket 2 from obscuring the phone logo and improving the overall aesthetics.

[0058] The magnetic component 23 enables the mobile phone to be compatible with external magnetic accessories (such as magnetic charging docks and magnetic brackets 2), expanding the functional scenarios of the protective case and breaking through the limitation of the existing bracket 2 which can only support a single function. Furthermore, the arc groove 211 design of the second arc part 21 can accurately position and fix the arc-shaped magnetic component 23. At the same time, setting the magnetic component 23 as a non-closed arc-shaped piece can reduce the impact of the setting of the magnetic component 23 on wireless charging, reduce the current generated by the magnetic component 23 under electromagnetic induction, and avoid interference with wireless charging.

[0059] The rotating connection 22 and the rotating seat 3 rotate together to ensure that the bracket 2 flips smoothly. Combined with the positioning function of the rotating seat 3, it realizes the dual functions of "support angle adjustment + magnetic attraction function", which improves the ease of use for operators and the adaptability to different scenarios.

[0060] In one embodiment, the bracket 2 further includes an annular cover plate 24, which covers the second arcuate portion 21 and the first arcuate portion 25 and closes the arcuate groove 211.

[0061] like Figure 1 As shown, in one embodiment, the housing 1 includes a back plate 11 and a side wall 12. The side wall 12 surrounds the edge of the back plate 11, and the side wall 12 and the back plate 11 enclose a receiving cavity for accommodating electronic products. The fastener is disposed on the back plate 11.

[0062] like Figure 12 and Figure 13As shown, in one embodiment, the bracket 2 includes a first support frame 26 and a second support frame 27. One side of the first support frame 26 is rotatably connected to the rotating seat 3, and the other side of the first support frame 27 is rotatably connected to one side of the second support frame 27. The housing 1 has a camera clearance hole 16 for exposing the camera module. In the initial state, the first support frame 26 and the second support frame 27 are fitted around the outer periphery of the camera module. In the use state, the first support frame 26 and the second support frame 27 rotate to disengage from the camera module.

[0063] In use, the first support frame 26 and the second support frame 27 are designed to provide support for the protective case 1, thus acting as a phone stand.
