[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] This utility model embodiment provides a mobile phone case 1000, such as... Figure 1 - Figure 6 As shown, the phone case 1000 includes a housing 10 and an unlocking mechanism 20. The housing 10 includes a first frame 11 and a second frame 12. The second frame 12 is located in a first direction (e.g., ...). Figure 1 On one side of the first frame 11 (as shown in the X direction), the second frame 12 is provided with a card holder 121 on the side facing the first frame 11. The card holder 121 is provided with a locking part 1211. The unlocking mechanism 20 includes an unlocking member 21 and a locking member 22. In the first direction, the unlocking member 21 is movably mounted on the first frame 11 and partially exposed outside the first frame 11. The unlocking member 21 has a first inclined surface 211, which is set at an angle to the first direction. The locking member 22 is located on the locking part 1211 in the second direction (as shown in the X direction). Figure 1 On one side of the first frame 11 (as shown in the Y direction), the second direction is set at an angle to the first direction. The locking member 22 is used to cooperate with the latching part 1211 to lock the first frame 11 and the second frame 12. The locking member 22 is provided with a second inclined surface 221 opposite to the first inclined surface 211, and the second inclined surface 221 is connected to the first inclined surface 211. The locking member 22 is movably installed in the first frame 11 in the second direction. When force is applied to the unlocking member 21, the first inclined surface 211 cooperates with the second inclined surface 221 to disengage the locking member 22 from the latching part 1211. The first elastic member 23 is installed in the first frame 11 and connected to the locking member 22 so that the locking member 22 is inserted into the latching part 1211 and the unlocking member 21 is reset. This application can solve the problem of easy scratching of mobile phones during the installation and removal of mobile phone cases in the prior art. The mobile phone case 1000 adopts a detachable connection, which not only avoids scratching the mobile phone, but also makes its installation and removal more convenient and quick.

[0038] Specifically, only force needs to be applied to the unlocking member 21 along the first direction. At this time, the first inclined surface 211 of the unlocking member 21 interacts with the second inclined surface 221 of the locking member 22, converting the movement of the unlocking member 21 in the first direction into the movement of the locking member 22 in the second direction, causing the locking member 22 to disengage from the latching part 1211. Subsequently, the second frame 12 can be displaced and separated relative to the first frame 11 along the first direction, and the mobile phone can be easily removed from the housing 10. Furthermore, during the installation process, there is no need to reverse the operation of the unlocking member 21 to return the second frame 12 to its original position. The first elastic member 23 will drive the locking member 22 to re-insert into the latching part 1211, so that the second frame 12 and the first frame 11 are automatically locked. At this time, the locking member 22 will also drive the unlocking member 21 to reset, preparing for the next disassembly. Compared with the prior art embodiment of the mobile phone case 1000 using a set method, during the installation and disassembly process, the first frame 11 and the second frame 12 do not directly contact or rub against the surface of the mobile phone, thereby avoiding the risk of the mobile phone case being scratched. Meanwhile, the entire operation process is simple and quick, greatly enhancing the user experience.

[0039] In addition, the first elastic member 23 can apply force to the locking member 22, so that the locking member 22 maintains the relative position with the locking part 1211 after locking, thereby improving the reliability after locking.

[0040] It should be noted that when the first frame 11 and the second frame 12 are connected, they together enclose an installation space for accommodating and installing the mobile phone. When the first frame 11 and the second frame 12 are separated, the installation space is released, so that the mobile phone can be easily removed.

[0041] The second direction is set at an angle to the first direction, and the size of the angle is not limited here. For example, in this application, the second direction is perpendicular to the first direction.

[0042] Similarly, the first inclined surface 211 is set at an angle to the first direction, and the size of the angle is not limited here. For example, in this application, the first inclined surface 211 is at 45° to the first direction.

[0043] The unlocking component 21 is located on the side of the first frame 11 facing away from the installation space, that is, it is located on the back of the first frame 11. It can be understood that the unlocking component 21 can also be located on the side of the first frame 11 in the first direction. The location of the unlocking component 21 is not limited here.

[0044] There are many ways to unlock the unlocking device 21. For example, the unlocking device 21 is unlocked by tossing; for another example, in this application, the unlocking device 21 is unlocked by sliding. The unlocking method of the unlocking device 21 is not limited here.

[0045] There are many ways to arrange the first frame 11 and the second frame 12. For example, in this application, the first frame 11 includes a first base 116 and two first clamping arms 117. The unlocking mechanism 20 is mounted on the first base 116. The two first clamping arms 117 are connected to the first base 116. A first clearance space 118 is provided between the two first clamping arms 117. The second frame 12 includes a second base 122 and two second clamping arms 123. The two second clamping arms 123 are connected to the second base 122. The card holder 121 is disposed on the second base 122. A second clearance space 124 is provided between the two second clamping arms 123. A third clearance space 13 is provided between any adjacent first clamping arms 117 and second clamping arms 123. The two first clamping arms 117 are used to cooperate with the two second clamping arms 123 to clamp the four corners of the mobile phone. Thus, the first clearance space 118, the second clearance space 124, and the third clearance space 13 expose the phone body to the outside of the phone case 1000, which helps the phone dissipate heat and, while protecting the phone, also restores the feel of holding the phone without a case, improving the user experience.

[0046] The dimensions of the first frame 11 and the second frame 12 can be adjusted according to actual design requirements and are not limited here. For example, in the first direction, the first frame 11 and the second frame 12 are symmetrically arranged. Alternatively, in the first direction, the first frame 11 and the second frame 12 are asymmetrically arranged, with the side of the first frame 11 closer to the second frame 12 located below the center of the phone. In this way, the first frame 11 occupies a larger space, which is beneficial for arranging the unlocking mechanism 20 and other components.

[0047] In one embodiment, shock-absorbing pads are provided at both the first clamping arm 117 and the second clamping arm 123. Thus, when the phone is accidentally dropped, the shock-absorbing pads can absorb the impact, reducing the possibility of damage and improving the protective properties of the phone case 1000. Specifically, four shock-absorbing pads are provided, each corresponding to one of the four corners of the phone.

[0048] Combination Figure 7In one embodiment, the first frame 11 is provided with a slide groove 111 on the side facing the second frame 12, the card seat 121 is slidably disposed in the slide groove 111, and the slide groove 111 is provided with a mounting seat 112 on the groove wall. The mounting seat 112 is provided with a first guide groove 1121 and a second guide groove 1122. The second guide groove 1122 is located at one end of the first guide groove 1121 facing the groove opening of the slide groove 111. The locking member 22 is slidably connected to the second guide groove 1122, and the unlocking member 21 is slidably connected to the first guide groove 1121. The first inclined surface 211 extends into the second guide groove 1122 and abuts against the second inclined surface 221. The locking member 22 can extend or retract into the second guide groove 1122. Thus, the mounting base 112 and the slide groove 111 are designed to ensure that the locking part 1211 can be precisely aligned with the locking member 22. Furthermore, the unlocking member 21 is installed in the first guide groove 1121 and the locking member 22 is installed in the second guide groove 1122. The first guide groove 1121 and the second guide groove 1122 can improve the connection stability between the unlocking member 21 and the locking member 22, so that the first inclined surface 211 and the second inclined surface 221 can always be aligned and connected, ensuring that the force applied by the unlocking member 21 to the locking member 22 can be reliably converted into the movement of the locking member 22 in the second direction, thereby improving the stability and reliability of locking and unlocking.

[0049] Reference Figure 5 and Figure 6 In one embodiment, the card holder 121 includes a sidewall 1212 facing the second guide groove 1122, and the latching portion 1211 is a groove 1212a provided in the sidewall 1212. One end of the locking member 22 facing the card holder 121 is adapted to the groove 1212a. This configuration improves the connection stability between the latching portion 1211 and the locking member 22, prevents the phone case 1000 from loosening or shifting during use, and enhances the reliability of the phone case 1000.

[0050] Specifically, the shapes of the lock 22 and the groove 1212a can be adjusted according to design requirements, as long as they are compatible, and no limitation is made here.

[0051] Reference Figure 5 and Figure 6In one embodiment, a mounting groove 1122a is provided at the bottom wall of the second guide groove 1122. A first elastic member 23 is installed in the mounting groove 1122a and is sandwiched between the bottom 1122a of the mounting groove 1122a and the locking member 22. When the locking member 22 is unlocked, the first elastic member 23 compresses and stores energy, and when it releases energy, it drives the locking member 22 to reset. The first elastic member 23 can drive the locking member 22 to have a tendency to move toward the opening of the second guide groove 1122, that is, one end of the locking member 22 can remain extended out of the opening of the second guide groove 1122. When the card holder 121 moves to the point where the locking part 1211 is opposite to the opening of the second guide groove 1122, the first elastic member 23 releases energy. The elastic force generated by the first elastic member 23 drives the locking member 22 to extend out of the opening and cooperate with the locking part 1211. The mounting groove 1122a restricts the first elastic element 23 from misalignment, preventing it from tilting and ensuring that the force applied by the first elastic element 23 is fully applied to the locking element 22, thus improving locking efficiency. Specifically, the first elastic element 23 is a spring.

[0052] In one embodiment, the card holder 121 includes a bottom wall opposite to the bottom of the slide groove 111. A first chamfer is provided at the edge of the bottom wall, and a second chamfer is provided on the side of the locking member 22 facing the opening of the slide groove 111. The first and second chamfers abut against each other, causing the locking member 22 to retract into the second guide groove 1122. With this configuration, as the card holder 121 moves towards the bottom of the slide groove 111, the first and second chamfers abut against each other, generating a force on the locking member 22 in a second direction. This force overcomes the elastic force of the first elastic member 23, causing the locking member 22 to retract into the second guide groove 1122. This reduces jamming during the engagement of the card holder 121 and the locking member 22, allowing the locking member 22 to engage more smoothly with the locking part 1211, thus improving operational efficiency. Specifically, the first and second chamfers can be bevels or rounded corners, and are not limited here.

[0053] Reference Figure 5 and Figure 6 In one embodiment, the phone case 1000 further includes a second elastic element 30, which is installed in the first frame 11 and connected to the card holder 121 to compress and store energy when the locking member 22 and the latching part 1211 are locked. The second elastic element 30 causes the card holder 121 to tend to move away from the bottom of the slide groove 111. When locked, the second elastic element 30 compresses and stores energy, and when unlocked, the second elastic element 30 releases energy and uses the generated elastic force to push the card holder 121 towards the opening of the slide groove 111, so that the second frame 12 can automatically disengage from the second frame 12 after unlocking, simplifying the unlocking steps and making the entire disassembly process smoother and faster. Specifically, the second elastic element 30 is a spring.

[0054] Reference Figure 5 and Figure 6In one embodiment, the card holder 121 includes two card arms 1213, which are arranged opposite to each other in a second direction. The unlocking mechanism 20 is located between the two card arms 1213, and the locking part 1211 is disposed on one of the card arms 1213. Two second elastic members 30 are provided, which are respectively connected between the two card arms 1213 and the bottom of the slide groove 111. This arrangement increases the number of second elastic members 30, allowing the card holder 121 to be separated from the first frame 11 by sufficient force. On the other hand, the second elastic members 30 are respectively connected to the two card arms 1213, making the force on the card holder 121 more balanced, ensuring that the card holder 121 can slide smoothly in the slide groove 111 and reducing the occurrence of jamming.

[0055] Reference Figure 6 and Figure 7 In one embodiment, the card holder 121 is provided with a limiting block 1214, and the groove of the slide 111 is provided with a blocking block 1111. In the sliding direction of the card holder 121, the projection of the blocking block 1111 and the projection of the limiting block 1214 at least partially overlap, and the limiting block 1214 can move to abut against the blocking block 1111. With this configuration, the limiting block 1214 and the blocking block 1111 ensure that after the second frame 12 is unlocked and separated from the first frame 11, the second frame 12 still maintains a connection and engagement with the first frame 11, and the two will not completely separate. This makes it convenient for the phone to be reinstalled into the phone case 1000, and makes the locking operation more convenient and efficient.

[0056] Reference Figure 8 In one embodiment, the back of the first frame 11 is provided with a receiving groove 113, which accommodates a support member 114. The support member 114 is rotatably mounted in the receiving groove 113 and can be flipped out of the receiving groove 113 to support the housing 10. With this configuration, when a mobile phone needs to be supported, the user can flip the support member 114 out of the receiving groove 113 to support the mobile phone, and by adjusting the angle between the support member 114 and the mobile phone housing 1000, the mobile phone can be placed at a suitable tilt angle, making it convenient for the user to watch videos or operate the screen, thus improving ease of use.

[0057] In one embodiment, a rotating seat 115 is rotatably disposed within the receiving groove 113, and a support member 114 is mounted on the rotating seat 115. With this configuration, the support member 114 can rotate relative to the receiving groove 113 via the rotating seat 115. When the phone needs to be viewed in portrait or landscape orientation, the support member 114 can be flipped out of the receiving groove 113 and further rotated to adjust it to the most suitable support position for the current screen orientation, thereby improving the support effect.

[0058] Reference Figure 4 and Figure 9In one embodiment, the rotating seat 115 is a frustum, and a toothed ring 1151 is provided on the outer peripheral surface of the frustum. The phone case 1000 also includes a positioning component 40, which is installed inside the first frame 11 and located on one radial side of the rotating seat 115. The positioning component 40 is used to engage with any tooth groove of the toothed ring 1151 to lock the rotating seat 115. With this configuration, the positioning component 40 can lock the rotating seat 115, ensuring that the rotating seat 115 will not accidentally deflect, improving the reliability of the overall structure, and providing a large rotation adjustment range to better meet the application needs of different scenarios.

[0059] Specifically, the positioning component 40 includes a positioning post 41 and a third elastic element 42. The first frame 11 has a fixed groove communicating with the receiving groove 113. The third elastic element 42 is sandwiched between the positioning post 41 and the bottom of the fixed groove. One end of the positioning post 41, away from the bottom of the fixed groove, extends into the receiving groove 113 and engages with the toothed groove of the gear ring 1151. The third elastic element 42 ensures that the positioning post 41 always tends to move towards the gear ring 1151. The positioning post 41 is held in place by an elastic force at any toothed groove of the gear ring 1151. When the rotating seat 115 is rotated, the positioning post 41 is forced to retract into the fixed groove, overcoming the elastic force of the third elastic element 42. At this time, the third elastic element 42 compresses and stores energy. After the rotating seat 115 is adjusted to the desired position, the third elastic element 42 releases energy to drive the positioning post 41 to reset, thus engaging the positioning post 41 with the currently corresponding toothed groove, achieving locking. This configuration allows the support member 114 to be infinitely adjustable, making adjustment more convenient.

[0060] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
