Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories, and more particularly to protective cases for mobile terminals. Background Technology

[0002] Phone cases are typically fitted onto phones to protect their outer surface. Current technology often includes lens covers on the case to protect the camera module. However, besides the lens, a phone's camera module usually includes components like a flash, microphone, and LiDAR. Existing lens covers not only obstruct the lens but also these other components, such as the flash (which can be used as a flashlight). This means users have to open the lens cover to access these other functions, which is inconvenient. Utility Model Content

[0009] In some embodiments, a first through hole is provided for displaying a plurality of rear cameras of the mobile terminal; a second through hole is provided for displaying the flash and microphone of the mobile terminal; the first through hole and the second through hole are spaced apart along the width direction of the protective shell body.

[0010] In some embodiments, when the protective cover is in the first position, the minimum distance L between the circumferential sidewall of the protective cover and the wall of the first through hole satisfies

[0011] L≥(H+h) / tan30°

[0012] Wherein, H is the thickness of the protective cover, and h is the minimum distance from the top surface of the rear lens to the upper surface of the protective shell body.

[0013] In some embodiments, the protective shell body includes a shell and a bracket mounted on the shell. The shell is provided with mounting holes, which are set to correspond to the rear camera and flash of the mobile terminal. The size of the bracket is set to correspond to the size of the mounting holes. The first through hole and the second through hole are both opened in the bracket. The protective cover and the bracket are connected by the pivot assembly, and the pivot assembly is located between the first through hole and the second through hole.

[0014] In some embodiments, the housing is provided with a receiving groove for accommodating a mobile terminal, and the bracket includes a first part and a second part connected together, the thickness of the first part being less than the thickness of the second part, such that the bracket is recessed on the side away from the receiving groove to form a receiving portion; the first through hole is provided on the first part, and the second through hole is provided on the second part; when the protective cover is in the second position, the protective cover can be completely accommodated in the receiving portion.

[0015] In some embodiments, the pivot assembly is disposed on the first portion, and when the protective cover is in the first position or the second position, the circumferential sidewall of the protective cover abuts against the sidewall of the second portion near the first portion.

[0016] In some embodiments, the protective cover has a chamfer, and the chamfer on the protective cover near the pivot assembly has an arc portion, which always maintains sliding contact with the side wall of the second portion near the first portion when the protective cover rotates between the first position and the second position.

[0017] In some embodiments, the protective cover has adjacent first side and second side. When the protective cover is in the second position, the first side is close to the second part, and the first side is provided with a chamfered portion. The chamfered portion is disposed opposite to the pivot assembly along the length direction of the protective shell body, and the chamfered portion extends obliquely from the middle section of the first side to the second side.

The limiting part and the elastic element are provided with positioning structures that cooperate with each other. When the protective cover is rotated to the first position or the second position, the positioning structure generates positioning resistance and prevents the rotating shaft assembly from continuing to rotate.

[0021] Implementing the embodiments of this utility model will have the following beneficial effects:

[0022] After adopting the aforementioned protective case for the mobile terminal, by moving the protective cover to the first position in a preset manner, the first through hole is exposed, and the rear camera of the mobile terminal is not obstructed and can be used. Alternatively, by moving the protective cover to the second position, which obstructs the first through hole, the rear camera of the mobile terminal is protected from scratches or pressure. Since the protective cover does not obstruct the second through hole in either the first or second position, the flash exposed through the second through hole can be activated at any time without being affected by the protective cover, and no additional operation is required on the protective cover, thereby improving the user experience.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] See appendix Figure 1 -Appendix Figure 14 This utility model proposes a protective case for a mobile terminal, comprising: a protective case body 1 and a protective cover 2. The protective case body 1 is provided with a first through hole 111 and a second through hole 112; the first through hole 111 and the second through hole 112 are spaced apart; the first through hole 111 is used to expose at least one rear camera 80 of the mobile terminal 8; the second through hole 112 is used to expose at least one flash 81 of the mobile terminal 8; the protective cover 2 is movably connected to the protective case body 1; the protective cover 2 moves along the upper surface of the protective case body 1, and when the protective cover 2 is in a first position, the first through hole 111 is exposed; when the protective cover 2 is in a second position, the protective cover 2 blocks the first through hole 111; and when the protective cover 2 is in either the first or second position, the second through hole 112 is exposed.

[0051] Specifically, the mobile terminal 8 can be understood as a portable electronic device such as a smartphone or tablet. This utility model uses a smartphone as an example, but is not limited to this. Smartphones generally have multiple rear cameras 80 and a flash 81. The protective case body 1 includes a housing 10 for mounting the smartphone and a bracket 11 mounted on the housing 10. Specifically, the housing 10 has a mounting hole 100. After the housing 10 is placed on the smartphone, the mounting hole 100 exposes the back area of ​​the smartphone with the rear cameras 80 and the flash 81. The bracket 11 is sized to correspond to the mounting hole 100. The bracket 100 is provided on the housing 10 to support the electronic device and is set to correspond to the mounting hole 100. The bracket 100 can be hidden when combined with the protective cover 2. When it is necessary to support the electronic device, the bracket 11 can be opened for use. In other embodiments, the bracket 100 may not be provided, and the protective cover 2 may be directly connected to the housing 10. This embodiment is described with the protective case body 1 including the housing 10 and the bracket 11 mounted on the housing 10. The bracket 11 can be assembled at the mounting hole 100 using a hinge 113 and a snap-fit ​​connection. Alternatively, the bracket 11 and the housing 10 can also be integrally formed, or connected by a sliding groove 42, etc. Figure 4 , Figure 7 and Figure 10 The first through hole 111 and the second through hole 112 are both distributed on the bracket 11, so that the first through hole 111 is aligned and exposes multiple rear lenses 80, and the second through hole 112 is aligned and exposes the flash 81; the protective cover 2 can be connected to the bracket 11 by means of rotation, sliding, etc., and the protective cover 2 moves along the upper surface of the bracket 11. In other words, the protective cover 2 remains parallel to the upper surface of the bracket 11 in the first position, the second position, and during the movement; in use, by moving the protective cover 2 to the first position in a preset manner, so that... With the first through-hole 111 exposed, the rear camera 80 of the mobile terminal 8 is not obstructed, and the electronic device can use the rear camera. Alternatively, the protective cover 2 can be moved to a second position that obstructs the first through-hole 111, in which case the rear camera 80 of the mobile terminal 8 is protected from scratches or pressure. Since the protective cover 2 does not obstruct the second through-hole 112 in either the first or second position, the flash 81 exposed through the second through-hole 112 can be activated at any time without being affected by the protective cover 2, and no additional operation is required on the protective cover 2, thereby improving the user experience.

[0052] Reference Figures 1 to 8 In some embodiments, multiple first through holes 111 are provided, each corresponding to a different rear camera 80 of the mobile terminal 8. The multiple first through holes 111 are arranged adjacently to form a first hole group. Two second through holes 112 are provided, each corresponding to a different flash 81 and microphone 82 of the mobile terminal 8. The two second through holes 112 are arranged adjacently to form a second hole group. The first hole group and the second hole group are spaced apart along the width direction of the protective shell body 1. Specifically, the multiple rear cameras 80 can be understood as main cameras, The number of first through-holes 111 for wide-angle and telephoto lenses can be matched one-to-one with the number of rear lenses 80, so that the main lens, wide-angle lens, and telephoto lens can all be exposed through the corresponding first through-holes 111 for shooting; the number of second through-holes 112 is at least two, and the number of second through-holes 112 is associated with the number of functional components on the back of the mobile terminal 8, such as flash 81, microphone 82, infrared sensor, and LiDAR 83, so that these functional components can be exposed through the multiple second through-holes 112 for normal use by the user of the mobile terminal 8; such as Figure 4 and Figure 5The back of the mobile terminal 8 has functional components such as a flash 81 and a microphone 82, as well as multiple rear cameras 80, arranged horizontally. Therefore, the first hole group and the second hole group are spaced apart along the width direction of the protective shell body 1, so that the first hole group can expose multiple rear cameras 80, and the second hole group can expose functional components such as the flash 81 and the microphone 82. It should also be noted that the first hole group and the second hole group can be set according to the distribution and arrangement of the cameras and flash 81 on the back of the mobile terminal 8. For example, when the rear cameras 80 and the flash 81 are arranged along the length direction of the mobile terminal 8, the first hole group and the second hole group are spaced apart along the length direction of the protective shell body 1.

[0053] Reference Figure 10 In some embodiments, a first through-hole 111 is provided for exposing multiple rear cameras 80 of the mobile terminal 8; a second through-hole 112 is provided for exposing the flash 81 and microphone 82 of the mobile terminal 8; the first through-hole 111 and the second through-hole 112 are spaced apart along the width direction of the protective shell body 1, and the aperture of the first through-hole 111 can be determined according to the circumcircle formed by the multiple rear cameras 80, so that the first through-hole 111 can simultaneously expose multiple rear cameras 80, and the first through-hole 111 is arranged according to the arrangement of the multiple rear cameras 80. The distribution can be specifically set as a circular hole, a square hole, or an irregularly shaped hole. The second through hole 112 is specifically set as a circular hole, a square hole, or an irregularly shaped hole according to the arrangement of the flash 81, microphone 82, and lidar 83 of the mobile terminal 8. When the functional components such as the rear camera 80 and the flash 81 are distributed along the width direction of the mobile terminal 8, the first through hole 111 and the second through hole 112 are respectively set at intervals along the width direction of the protective shell body 1, so that the first through hole 111 exposes multiple rear cameras 80, and the second through hole 112 exposes the flash 81, microphone 82, and lidar 83.

[0054] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8In some embodiments, the protective shell body 1 includes a shell 10 and a bracket 11 mounted on the shell 10. The first through hole 111 and the second through hole 112 are both formed in the bracket 11. The protective cover 2 and the bracket 11 are connected by a pivot assembly 3, and the pivot assembly 3 is located between the first through hole 111 and the second through hole 112. The area of ​​the protective cover 2 only covers the first through hole 111 and does not cover the second through hole 112, ensuring that the protective cover 2 does not block the second through hole 112 in either the first or second position. Since the bracket 11 is adapted to the rear lens module, the smaller the size, the better the user experience. Therefore, the bracket 11 usually just covers the lens module of the electronic device. Assuming that the pivot assembly 3 is located on the side of the first through hole 111 away from the second through hole 112, there is no space to install the pivot assembly 3, which will increase the size of the bracket 11. Moreover, when the protective cover 22 covering the rear lens 80 is in the first position, the probability of the protective cover 22 blocking the rear lens 80 increases, which increases the difficulty of installing the pivot assembly 3. The pivot assembly 3 is positioned between the first through hole 111 and the second through hole 112, making it easy to install and allowing for a smaller size, thus improving the user experience. Specifically, one side of the bracket 11 along its length is connected to the housing 10 via a hinge 113, while the other side of the bracket 11 without the hinge 113 is fixed to the housing 10 using snap-fit, fastening, or adhesive methods. This allows the bracket 11 to be flipped in specific scenarios, facilitating the assembly of the bracket 11 with the housing 10 and other components on the bracket 11. Figure 6 The rotating shaft assembly 3 includes a rotating rod 30 and a limiting washer 31. The rotating rod 30 is integrally formed on the protective cover 2 and protrudes from the bottom surface of the protective cover 2. A connecting hole 114 is provided on the bracket 11. One end of the rotating rod 30 passes through the connecting hole 114, enabling the protective cover 2 and the bracket 11 to be rotatably connected. The protective cover 2 rotates around the rotating rod 30 along the upper surface of the bracket 11. The limiting washer 31 is fixed to the end of the rotating rod 30 that passes through the bracket 11 by means of snap-fit ​​or threaded connection. The radial dimension (length, width, or diameter) of the limiting washer 31 is larger than the diameter of the connecting hole 114, thereby axially limiting the rotating rod 30 and improving the connection stability between the protective cover 2 and the bracket 11. Figure 6 and Figure 7 The connecting hole 114 is located between the first through hole 111 and the second through hole 112, and is specifically opened at the edge of the bracket 11. The rotating rod 30 is formed at one end corner of the protective cover 2, so that the protective cover 2 can be rotated from the second position to the first position or from the first position to the second position by a small rotation angle.

[0055] The housing 10 has a receiving groove for accommodating a mobile terminal. To make the structure of the protective housing more compact and aesthetically pleasing, the bracket 11 includes a first part 11a and a second part 11b connected together. The thickness of the first part 11a is less than the thickness of the second part 11b, so that the side of the bracket 11 away from the receiving groove is recessed to form a receiving portion 110. A first through hole 111 is provided on the first part 11a, and a second through hole 112 is provided on the second part 11b. When the protective cover 2 is in the second position, the protective cover 2 can be completely accommodated in the receiving portion 110. Specifically, the depth of the receiving portion 110 is greater than or equal to the depth of the protective cover 2. The thickness of the cover 2 allows it to be completely housed within the receiving portion 110 when in the second position, and the upper surface of the cover 2 is flush with the upper surface of the second portion 11b, preventing the cover 2 from protruding from the bracket 11 and thus reducing the thickness of the protective shell. In addition, the shape of the receiving portion 110 is the same as the shape of the cover 2, so that when the cover 2 is in the second position, it completely covers the upper surface of the receiving portion 110, preventing the cover 2 from protruding from the bracket 11 along its length or width direction. This improves the overall structural compactness of the protective shell and makes it more aesthetically pleasing.

[0056] Reference Figure 2 , Figure 7 and Figure 8 In some embodiments, the rotating shaft assembly 3 is disposed on the first part 11a, and when the protective cover 2 is in the first position or the second position, the circumferential sidewall of the protective cover 2 abuts against the sidewall of the second part 11b near the first part 11a. Specifically, the connecting hole 114 is opened at the position of the first part 11a near the second part 11b. Due to the thickness difference between the first part 11a and the second part 11b, a sidewall is naturally formed on the side of the second part 11b near the receiving part 110. For ease of explanation, this sidewall can be defined as the limiting wall 11b1. The axial sidewall of the protective cover 2 specifically includes a second side 22 and a third side 23 opposite to each other, and a first side 21 connecting the second side 22 and the third side 23. The rotating rod 30 of the rotating shaft assembly 3 is fixed to the protective cover 2. When the protective cover 2 is rotated to the first position exposing the first through hole 111, the adjacent corners of the first side 21 and the third side 23 abut against the limiting wall 11b1, preventing the protective cover 2 from rotating in that direction and thus avoiding excessive rotation of the protective cover 2 that would block the second through hole 112. Conversely, when the protective cover 2 is rotated to the second position that blocks the first through hole 111, the first side 21 of the protective cover 2 abuts against the limiting wall 11b1, preventing the protective cover 2 from rotating in that direction and thus avoiding excessive rotation of the protective cover 2 that would block the second through hole 112. This ensures that the second through hole 112 is always exposed, regardless of whether the protective cover 2 is in the first or second position, so that the user can activate the flash 81, microphone 82, and other functional components at any time.

[0057] Reference Figure 8 In some embodiments, the protective cover 2 has a chamfer 24 on its edge, and the rotating shaft assembly 3 is connected to the end corner of the protective cover 2 (located near the chamfer 24). The chamfer on the protective cover 2 near the rotating shaft assembly 3 has an arc portion. For example, the center of the arc portion coincides with the rotation center of the rotating assembly. When the protective cover 2 rotates between the first position and the second position, the arc portion of the chamfer 24 always maintains sliding contact with the side wall of the second part 11b near the first part 11a. Specifically, the arc portion of the chamfer 24 is specifically an angle formed by the first side 21 and the third side 23. By setting this angle to an arc shape, and because the center of the arc portion coincides with the rotation center of the rotating assembly, That is, when the protective cover 2 is in any position, the distance from the rotation center to the limiting wall 11b1 is the radius of the chamfer 24, ensuring that the chamfer 24 always maintains sliding contact with the side wall of the second part 11b close to the first part 11a. This can not only form a relief structure when the protective cover 2 rotates, but also improve the stability of the protective cover 2 during rotation. It should also be noted that the first side 21 and the third side 23 are perpendicular to each other, and the limiting wall 11b1 extends at least partially along the length direction of the protective shell body 1. The perpendicular first side 21 and the third side 23 allow the protective cover 2 to switch from the second position to the first position or from the first position to the second position by rotating 90°.

[0058] Reference Figure 3 , Figure 7 and Figure 8 In some embodiments, when the protective cover 2 is in the second position, the first side 21 is close to the second part 11b, and the first side 21 is provided with a beveled portion 210. The beveled portion 210 and the rotating shaft assembly 3 are arranged opposite to each other along the length direction of the protective shell body 1, which is, for example, the length direction of the shell 10. The beveled portion 210 extends obliquely from the middle section of the first side 21 to the middle section of the second side 22, so that when the protective cover 2 rotates 90° from the second position to the first position, the protective cover 2 will not block the first through hole 111 opened in the second part 11b because an avoidance notch is formed at the position of the beveled portion 210. The cover 2 is designed to switch between the first and second positions with a smaller rotation angle, ensuring that the first through hole 111 is fully exposed when the cover 2 is in the first position and completely covered when the cover 2 is in the second position. The second part 11b protrudes outward from the shape of the first side 21 of the cover 2, forming a beveled protrusion that fits against the beveled portion 210. This ensures that when the cover 2 is in the second position, the first side 21 of the cover 2 is fully fitted against the side wall of the second part 11b near the receiving portion 110. It should also be noted that the beveled portion 210 can be a straight edge, an arc edge, or a wavy edge, which can be set according to user requirements.

[0059] To ensure that the circumferential sidewall of the protective cover 2 does not interfere with the viewing angle of the rear lens 80 within the first through hole 111 when the protective cover 2 is in the first position, in some embodiments, the minimum distance L between the circumferential sidewall of the protective cover 2 and the wall of the first through hole 111 when the protective cover 2 is in the first position satisfies:

[0060] L≥(H+h) / tan30°,

[0061] Where H is the thickness of the protective cover 2, and h is the minimum distance from the upper surface of the rear lens 80 to the upper surface of the protective shell body 1, specifically the distance from the upper surface of the rear lens 80 to the upper surface of the first part 11a of the bracket 11, such as... Figure 9 The beveled portion 210 is the circumferential sidewall of the protective cover 2 closest to the first through hole 111. Taking this as an example, L is the minimum distance between the beveled portion 210 and the wall of the first through hole 111. Since the rear lens 80 has such Figure 9 The two rays R constituting the viewing angle β shown can be considered as the light paths of the rear lens 80. That is, ray R cannot intersect with the protective cover 2. When the viewing angle β of the rear lens 80 is uniquely determined, the angle θ formed by the ray R and the upper surface of the rear lens 80 is also uniquely determined. As an example, when the angle of the viewing angle β of the rear lens 80 is 120°, the angle θ can be calculated to be 30° using the formula θ=(180-β) / 2. Based on this, and combined with the Pythagorean theorem, the minimum distance L between the oblique cut portion 210 of the protective cover 2 and the wall of the first through hole 111 needs to satisfy...

[0062] L≥(H+h) / tan30°,

[0063] This ensures that when the protective cover 2 is in the first position, it will not affect the normal shooting angle of the rear lens 80 inside the first through hole 111.

[0064] Reference Figure 11 In some embodiments, an anti-friction structure 4 is provided between the protective cover 2 and the protective shell body 1; the anti-friction structure 4 includes a wear-resistant component 40, and one of the protective cover 2 and the protective shell body 1 is provided with a wear-resistant component 40. The wear-resistant component 40 covers the bottom surface of the protective cover 2. Specifically, wear-resistant components 40 can be provided in both the protective cover 2 and the first part 11a of the bracket 11. The wear-resistant component 40 can be made of sheet-like wear-resistant materials such as Mylar sheet or patch, which can prevent the protective cover 2 from rubbing against the bracket 11 and wear, and also minimize the thickness of the protective shell.

[0065] Reference Figure 6 , Figure 7In some embodiments, the anti-friction structure 4 includes a protrusion 41 and a groove 42. One surface of the protective cover 2 and the protective shell body 1 is provided with a protrusion 41, and the other surface is provided with a groove 42. The protrusion 41 can slide within the groove 42, and the height of the protrusion 41 protruding from the corresponding component surface is greater than the depth of the groove 42. Specifically, a protrusion 41 can be provided on the upper surface of the first part 11a of the bracket 11, and a groove 42 can be provided on the bottom surface of the protective cover 2. Because the height of the protrusion 41 is greater than the depth of the groove 42, a gap is formed between the protective cover 2 and the bracket 11, thereby avoiding large-area contact and friction between the protective cover 2 and the bracket 11. To improve the compactness of the structure, while ensuring that a gap is formed between the bracket 11 and the protective cover 2, the height of the protrusion 41 can be greater than the depth of the groove 42. The depth difference of the slide groove 42 is set as small as possible; in addition, the slide groove 42 can be set as an arc groove according to the rotation trajectory of the protective cover 2. Since the protective cover 2 only needs to rotate 90° and can only switch between the first position and the second position, the central angle of the slide groove 42 is specifically 90°. That is, when the protrusion 41 is at any end of the length direction of the slide groove 42, the protective cover 2 is in the first position or the second position. The excessive rotation of the protective cover 2 is further restricted by the contact between the protrusion 41 and the two ends of the slide groove 42. In order to improve the stability of the protective cover 2 when rotating, there can be two protrusions 41 and two corresponding slide grooves 42. The two slide grooves 42 are distributed at intervals and arranged around the periphery of the rotating shaft assembly 3. The center of the two slide grooves 42 is the rotation center of the rotating shaft assembly 3.

[0066] Reference Figure 6 and Figure 11 In some embodiments, the protective cover 2 is provided with a first magnetic element 51, and the bracket 11 is provided with at least two second magnetic elements 52, which are spaced apart. When the protective cover 2 is in the first position, one second magnetic element 52 is magnetically attracted to the first magnetic element 51; when the protective cover 2 is in the second position, the other second magnetic element 52 is magnetically attracted to the first magnetic element 51. Specifically, the first magnetic element 51 and the second magnetic element 52 can be configured as follows: Figure 6 The circular magnet shown holds the protective cover 2 in a first position by magnetic attraction between the first magnetic element 51 and the second magnetic element 52, or holds it in a second position by magnetic attraction between the first magnetic element 51 and the second magnetic element 52. Furthermore, the magnetic attraction between the first magnetic element 51 and the second magnetic element 52 during the rotation of the protective cover 2 effectively improves the user's feel when rotating the cover to either the first or second position. Figure 11 In other embodiments, both the first magnetic element 51 and the second magnetic element 52 are arc-shaped strips, arranged around the periphery of the rotating shaft assembly 3, and the magnetic poles of the first magnetic element 51 distributed along its length are opposite to those of the second magnetic element 52 distributed along its length. Figure 11When the magnetic pole distribution of the first magnetic element 51 is N-S, the magnetic pole distribution of the second magnetic element 52 is SN. When the protective cover 2 is rotated to a position close to the first or second position, the attraction between the first magnetic element 51 and the second magnetic element 52 can be accelerated. When the protective cover 2 is disengaged from the first or second position, the attraction between the first magnetic element 51 and the second magnetic element 52 can be pushed away, further enhancing the user's feel when rotating the protective cover 2.

[0067] Reference Figure 12 , Figure 13 and Figure 14 In some embodiments, one of the bracket 11 and the rotating shaft assembly 3 is provided with a limiting part 6, and the other is provided with an elastic element 7. The limiting part 6 and the elastic element 7 are provided with mutually cooperating positioning structures. When the protective cover 2 rotates to the first position or the second position, the positioning structure generates positioning resistance, preventing the rotating shaft assembly 3 from continuing to rotate. Specifically, the limiting part 6 can be provided on the limiting pad 31 of the rotating shaft assembly 3, and the elastic element 7 can be provided on the surface of the bracket 11 away from the protective cover 2. The bracket 11 has a receiving groove on this surface for receiving the limiting pad 31 and the elastic element 7. The receiving groove prevents the limiting pad 31 and the elastic element 7 from protruding from the surface of the bracket 11, thus avoiding affecting the installation of the mobile terminal 8. The positioning structure can specifically adopt the following... Figure 12 The spring clip type shown is either press-fit or uses, as shown in the figure. Figure 13 and Figure 14 The interlocking type shown uses the resistance generated by the positioning structure to limit the rotation of the rotating shaft assembly 3, thereby keeping the protective cover 2 in the first or second position.

[0068] Reference Figure 12 In some embodiments, the positioning structure adopts a spring-loaded pressing type: the limiting part 6 consists of a first limiting edge 61 and a second limiting edge 62 adjacent to and perpendicular to the limiting pad 31, and the elastic element 7 is specifically a deformable straight spring 70. When the protective cover 2 is in the first position, the first limiting edge 61 abuts against the straight spring 70. When the protective cover 2 is in the second position, the second limiting edge 62 abuts against the straight spring 70, so that the protective cover 2 is kept in the first position or the second position. Furthermore, the corner formed by the first limiting edge 61 and the second limiting edge 62 is rounded, so that when the rotating rod 30 drives the limiting pad 31 to rotate, the corner forms a rotation avoidance and squeezes the straight spring 70 to deform, so that the first limiting edge 61 on the limiting pad 31 transitions to the second limiting edge 62 or the second limiting edge 62 transitions to the first limiting edge 61.

[0069] Reference Figure 13In some embodiments, the positioning structure adopts a concave-convex snap-fit ​​type: the limiting part 6 is a first limiting protrusion 63 radially protruding on the circumferential sidewall of the limiting pad 31, and the elastic element 7 is specifically a deformable arc-shaped spring sheet 71. Two spaced first limiting grooves 710 are provided on the arc-shaped spring sheet 71. The first limiting protrusion 63 can be snapped with any one of the first limiting grooves. During the rotation of the protective cover 2, the first limiting protrusion 63 always abuts against the arc-shaped spring sheet 71. When the protective cover 2 is in the first position, the first limiting protrusion 63 is snapped with one of the first limiting grooves 710. When the protective cover 2 is in the second position, the second limiting edge 62 is snapped with the other first limiting groove 710, so that the protective cover 2 is kept in the first position or the second position.

[0070] Reference Figure 14 In some embodiments, the positioning structure adopts a concave-convex snap-fit ​​type: the limiting part 6 is a second limiting groove 64 that is radially recessed on the circumferential sidewall of the limiting pad 31, and the elastic element 7 is two deformable convex springs 72. The convex springs 72 are provided with protrusions 720 that engage with the second limiting groove 64. During the rotation of the protective cover 2, the protrusions 720 always abut against the circumferential sidewall of the limiting pad 31. When the protective cover 2 is in the first position, the second limiting groove 64 engages with the protrusion 720 of one convex spring 72. When the protective cover 2 is in the second position, the second limiting groove 64 engages with the protrusion 720 of the other convex spring 72, so that the protective cover 2 is held in the first position or the second position.

[0071] The following are further examples combining the above content:

[0072] like Figures 1-9The first embodiment shown in this embodiment has a protective case for the mobile terminal, which includes a protective case body 1 and a protective cover 2. The protective case body 1 includes a housing 10 and a bracket 11 connected to the housing 10 via a hinge 113. The first part 11a of the bracket 11 has a plurality of first through holes 111, which correspond one-to-one with the plurality of rear cameras 80 of the mobile terminal 8. The second part 11b of the bracket 11 has a plurality of second through holes 112, which correspond one-to-one with the flash 81, microphone 82 and lidar 83 of the mobile terminal 8. The protective cover 2 is rotatably connected to the first part 11a of the bracket 11 via a pivot assembly 3. The first magnetic element 51 and the two second magnetic elements 52 are both disc-shaped. The first magnetic element 51 is attached to the bottom surface of the protective cover 2, and the two second magnetic elements 52 are attached to the side of the bracket 11 away from the protective cover 2, and the two second magnetic elements 52 are spaced apart. When the protective cover 2 is in the first position... The first magnetic element 51 is magnetically attracted to one of the second magnetic elements 52, so that the protective cover 2 is held in the first position. When the protective cover 2 is in the second position, the first magnetic element 51 is magnetically attracted to the other of the second magnetic elements 52, so that the protective cover 2 is held in the second position. The magnetic attraction between the first magnetic element 51 and the second magnetic element 52 can improve the user's feel when rotating the protective cover 2. In addition, in order to prevent friction between the protective cover 2 and the bracket 11, the anti-friction structure 4 specifically includes two corresponding protrusions 41 and two sliding grooves 42. The two protrusions 41 are disposed on the surface of the second part 11b of the bracket 11, and the two sliding grooves 42 are disposed on the bottom surface of the protective cover 2. By the protrusions 41 extending into the sliding grooves 42 and abutting against the bottom wall of the sliding grooves 42, a gap is formed between the protective cover 2 and the surface of the second part 11b of the bracket 11, thereby preventing friction between the protective cover 2 and the bracket 11.

[0073] like Figure 10 The protective case of the mobile terminal shown in Embodiment 2 is largely the same as that of the mobile terminal in Embodiment 1. The similarities will not be repeated here. The main difference is that the first through hole 111 and the second through hole 112 of the mobile terminal protective case in this embodiment are different from those of the mobile terminal protective case in Embodiment 1. Specifically, the first through hole 111 and the second through hole 112 of this embodiment are both provided. Multiple rear cameras 80 of the mobile terminal 8 are exposed through a single first through hole 111, and the flash 81, microphone 82 and lidar 83 of the mobile terminal 8 are exposed through a single second through hole 112.

[0074] like Figure 11The protective case of the mobile terminal shown in Embodiment 3 is largely the same as that of the mobile terminal in Embodiment 1, and the similarities will not be repeated here. The main difference lies in the anti-friction structure 4, the first magnetic component 51, and the second magnetic component 52 of the protective case of the mobile terminal in this embodiment. Specifically, the anti-friction structure 4 in this embodiment is a wear-resistant component 40, which is made of a fabric patch. The wear-resistant component 40 is attached to the bottom surface of the protective cover 2, so that the bottom surface of the protective cover 2 does not directly contact the surface of the second part 11b of the bracket 11. The soft properties of the wear-resistant part 40 achieve the purpose of preventing friction. In addition, in this embodiment, the first magnetic part 51 and the second magnetic part 52 are both arc-shaped strips, and the magnetic pole distribution of the first magnetic part 51 in its length direction is opposite to that of the second magnetic part 52 in its length direction. This arrangement makes the protective cover 2 accelerate the attraction of the first magnetic part 51 and the second magnetic part 52 when it is close to the first position or the second position, and accelerate the separation of the first magnetic part 51 and the second magnetic part 52 when it is far away from the first position or the second position, effectively improving the user's feel when rotating the protective cover 2.

[0075] like Figure 12 The protective case of the mobile terminal shown in Embodiment 4 is largely the same as that of the mobile terminal in Embodiment 1, and the similarities will not be repeated here. The main difference is that the protective case of the mobile terminal in this embodiment also has a limiting part 6 and an elastic member 7 between the pivot assembly 3 and the bracket 11. The limiting part 6 and the elastic member 7 are provided with mutually cooperating positioning structures, and the positioning structure in this embodiment adopts the following... Figure 12 The spring-loaded snap-fit ​​design shown in the diagram allows the protective cover 2 to be held in either the first or second position, thereby improving the structural stability of the protective shell.

[0076] like Figure 13 The protective case of the mobile terminal shown in Embodiment 5 is largely the same as that of the mobile terminal in Embodiment 4 above. The similarities will not be repeated here. The main difference lies in the positioning structure of this embodiment, which adopts the following... Figure 13 The interlocking design shown allows the protective cover 2 to be held in either the first or second position, thereby improving the structural stability of the protective shell.

[0077] like Figure 14 The protective case of the mobile terminal shown in Embodiment Six is ​​largely the same as that of the mobile terminal in Embodiment Four, and the similarities will not be repeated here. The main difference is that the positioning structure in this embodiment adopts the following... Figure 14The interlocking design shown allows the protective cover 2 to be held in either the first or second position, thereby improving the structural stability of the protective shell.
