In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art in the field of the present invention. The terms used in this specification are intended only to describe specific embodiments and are not intended to limit the present invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0027] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Existing AR mirrors are usually installed as separate components on terminal devices (such as tablets, learning machines, etc.), or removed from terminal devices. For users who need to use AR mirrors for auxiliary learning, they need to frequently remove and install the AR mirrors. They are not very portable and are easily lost after being removed from the terminal devices. In related technologies, by setting the AR mirror on a protective cover, the risk of losing the AR mirror can be reduced because the AR mirror and the protective cover are integrated. However, for users who do not need to use the AR mirror, the AR mirror on the protective cover appears redundant and takes up space, affecting the appearance of the protective cover.

[0029] To solve the above problems, the present application provides a protective case, which removably clips the AR mirror assembly to the shell. For users who need to use the AR mirror assembly, there is no need to frequently install or disassemble the AR mirror assembly, thereby reducing the risk of losing the AR mirror assembly; for users who do not need to use the AR mirror assembly, the AR mirror assembly can be removed from the shell, thereby reducing the space occupied by the protective case and improving the aesthetics of the protective case.

[0030] The specific structure and functions of this technical solution are described in detail below.

[0031] See also Figure 1 The protective case 100 includes a shell 1 and an AR mirror assembly 2. The AR mirror assembly 2 is removably arranged on the shell 1. The shell 1 is used to accommodate a terminal device (not shown) to protect the terminal device. The terminal device can be a tablet computer, a tablet-type learning machine, etc. The AR mirror assembly 2 is used to identify the content of the terminal device for auxiliary learning.

[0032] In some embodiments, see Figure 1 The shell 1 is provided with a receiving slot 11 and a card slot 12. The receiving slot 11 is used to receive the terminal device, and the card slot 12 is provided on a side wall of the shell 1. The AR mirror assembly 2 includes a main body 22 and a connector 21. The main body 22 is used to capture images; optionally, it can also be used to process the captured images. For example, the main body 22 captures documents placed in a preset range around the terminal device and identifies the documents to assist learning. The connector 21 is used to connect the main body 22 and the shell 1.

[0033] Specifically, one end of the connector 21 is removably engaged with the slot 12, and the body 22 is disposed at an end of the connector 21 away from the slot 12. When the AR mirror assembly 2 is mounted on the housing 1, the AR mirror assembly 2 can switch between a first state and a second state.

[0034] When the AR mirror assembly 2 is in the first state, refer to Figure 1 The main body 22 and the receiving slot 11 are spaced apart along the first direction X, and along the second direction Y, at least part of the main body 22 protrudes from the notch of the receiving slot 11, so that the main body 22 can identify the content of the terminal device in the receiving slot 11, wherein the second direction Y is parallel to the direction of the notch of the receiving slot 11.

[0035] When the AR mirror assembly 2 is in the second state, see Figure 2 The connecting member 21 is bent so that the body 22 abuts against the back surface 13 of the shell 1 , wherein the back surface 13 of the shell 1 is the surface of the shell 1 facing away from the receiving groove 11 , and the first direction X is parallel to the back surface 13 .

[0036] In this embodiment, for users who need to use the AR mirror assembly 2, when they need to use the AR mirror assembly 2, they can adjust the AR mirror assembly 2 to Figure 1 When the AR mirror assembly 2 is not needed, the AR mirror assembly 2 can be adjusted to Figure 2 In the second state shown, the AR mirror assembly 2 does not need to be removed, reducing the risk of losing the AR mirror assembly 2. In addition, by removably engaging one end of the connector 21 with the card slot 12, users who do not need to use the AR mirror assembly can also remove the AR mirror assembly 2 to reduce the space occupied by the AR mirror assembly 2 and improve the aesthetics of the protective case 100, thereby meeting the needs of different users.

[0037] In some embodiments, see Figure 3 and Figure 4 A first groove 211 is provided at one end of the connector 21 away from the body 22, and a first protrusion 1211 is provided on the first sidewall 121 of the slot 12. The first protrusion 1211 is engaged with the first groove 211, thereby achieving a snap-fit ​​connection between the connector 21 and the first slot 12. In this embodiment, by providing the first groove 211 and the first protrusion 1211, the first protrusion 1211 is engaged with the first groove 211 to achieve a removable connection between the AR mirror assembly 2 and the housing 1, which has a simple structure and is easy to assemble.

[0038] In some embodiments, see Figure 3 and Figure 4 The end of the connector 21 away from the body 22 is further provided with a second groove 212, and the second side wall 122 of the slot 12 is provided with a second protrusion 1221. The second side wall 122 is arranged opposite to the first side wall 121, and the second protrusion 1221 is engaged with the second groove 212. In this embodiment, by engaging the second protrusion 1221 with the second groove 212, the stability of the engagement between the connector 21 and the housing 1 can be improved, and the risk of the AR mirror assembly 2 being separated from the housing 1 can be reduced.

[0039] In some embodiments, see Figure 3 The protective shell 100 further includes a first magnetic member 3, which is embedded in the housing 1. The outer shell (not numbered) of the body 22 includes a magnetic material or the body 22 is embedded with a magnetic member (not shown). When the AR mirror assembly 2 is in Figure 2 In the second state shown in FIG, the first magnetic member 3 is magnetically attracted to the body 22 to secure the body 22 to the housing 1. This configuration reduces the risk of the AR mirror assembly 2 shaking when the AR mirror assembly 2 is in the second state. This prevents shaking of the body 22 from affecting the user's experience of using the terminal device, and also reduces the risk of collision between the body 22 and the housing 1, thereby protecting the body 22.

[0040] In some embodiments, see Figure 1 The protective shell 100 also includes a support component 4, which is arranged on the back side 13 of the shell 1. The support component 4 is used to support the shell 1 to facilitate the user to view or operate the terminal device in the shell 1.

[0041] In some embodiments, see Figure 1 and Figure 3 The support assembly 4 includes a support frame 41 and a connecting frame 42. One end of the support frame 41 is connected to the back surface 13 of the housing 1, and the other end of the support frame 41 is used to abut against a supporting surface, wherein the supporting surface can be a desktop, the ground, etc., which is used to support the protective case 100 and the terminal device. One end of the connecting frame 42 is connected to the back surface 13 of the housing 1, and the other end is connected to the support frame 41. The connecting frame 42, the support frame 41, and the back surface 13 of the housing 1 can form a triangular support structure together, thereby improving the stability of the support frame 41 in supporting the housing 1.

[0042] In some embodiments, see Figure 3 The support frame 41 includes a first fixing section 411 and a supporting section 412. The first fixing section 411 is connected to the back surface 13 of the housing 1. One end of the supporting section 412 is rotatably connected to the first fixing section 411, and the other end of the supporting section 412 is used to abut the supporting plane. The end of the connecting frame 42 away from the back surface 13 of the housing 1 is connected to the supporting section 412. In this embodiment, by rotatably connecting one end of the supporting section 412 to the first fixing section 411, the angle between the supporting section 412 and the back surface 13 of the housing 1 can be adjusted, thereby adjusting the inclination angle of the housing 1 relative to the supporting plane, so that the user can adjust the terminal device to an angle that is convenient for viewing or operation.

[0043] In some embodiments, see Figure 5 The protective shell 100 further includes a second magnetic member 5, which is disposed on the back surface 13 of the housing 1. The first fixing section 411 is embedded with a magnetic member (not shown) or the first fixing section 411 includes a magnetic material, so that the first fixing section 411 can generate magnetic attraction with the second magnetic member 5, thereby achieving fixation between the first fixing section 411 and the back surface 13 of the housing 1. In this embodiment, the first fixing section 411 is fixed to the housing 1 through the magnetic attraction between the second magnetic member 5 and the first fixing section 411, which has a simple structure and is easy to operate.

[0044] In some embodiments, the number of the second magnetic pieces 5 is multiple, the multiple second magnetic pieces 5 are all inlaid in the shell 1, and the multiple second magnetic pieces 5 are spaced apart along the first direction X, and the multiple second magnetic pieces 5 are all used to be magnetically attracted to the first fixed segment 411 to fix the first fixed segment 411 to the back surface 13 of the shell 1. Wherein, when the first fixed segment 411 is magnetically attracted to different second magnetic pieces 5, the position of the first fixed segment 411 in the first direction X relative to the shell 1 is different, so that the included angle between the support segment 412 and the back surface 13 of the shell 1 is different, and then the inclination angle of the shell 1 relative to the bearing plane is different to adapt to the needs of different users. For example, please refer to Figure 5 , the number of the second magnetic pieces 5 is three, and the three second magnetic pieces 5 correspond to three gears respectively, when the first fixed segment 411 is magnetically attracted to the second magnetic piece 5 closest to the AR lens assembly 2, as shown in Figure 6 , the support segment 412 is parallel to the back surface 13 of the shell 1, at this time, the support frame 41 is in the first gear, the support frame 41 is folded, and the support frame 41 cancels the support to the shell 1; when the first fixed segment 411 is magnetically attracted to the second magnetic piece 5 in the middle, as shown in Figure 2 , the support frame 41 is in the second gear, at this time, the included angle between the support segment 412 and the back surface 13 of the shell 1 is a first preset included angle, and the support segment 412 supports the shell 1 to a first position; when the first fixed segment 411 is magnetically attracted to the second magnetic piece 5 farthest from the AR lens assembly 2, as shown in Figure 7 , the support frame 41 is in the third gear, at this time, the included angle between the support segment 412 and the back surface 13 of the shell 1 is a second preset included angle, and the support segment 412 supports the shell 1 to a second position, wherein the second preset included angle is greater than the first preset included angle. In this embodiment, by arranging multiple second magnetic pieces 5, when the first fixed segment 411 is magnetically attracted to different second magnetic pieces 5, the included angle between the first fixed segment 411 and the back surface 13 of the shell 1 is different, so that the inclination angle of the shell 1 can be adjusted, so that the user can adjust the shell 1 to a comfortable angle according to his own needs.

[0045] It is worth noting that when the number of the second magnetic pieces 5 is multiple, the distance between two adjacent second magnetic pieces 5 can be the same or different, which is not limited in the present application.

[0046] In some embodiments, please refer to Figure 5The connecting frame 42 includes a second fixed section 421, a connecting section 422, and a third fixed section 423. One end of the connecting section 422 is connected to the second fixed section 421, and the connecting section 422 can swing relative to the second fixed section 421. The other end of the connecting section 422 is connected to the third fixed section 423, and the third fixed section 423 can swing relative to the connecting section 422. The second fixed section 421 is fixed to the back surface 13 of the shell 1, and the third fixed section 423 is fixed to the above-mentioned support section 412. With this arrangement, when the support frame 41 switches to different gears (i.e., the first fixed section 411 is magnetically attracted to different second magnetic members 5), the connecting frame 42 can remain connected to the support section 412 and the back surface 13 of the shell 1, so as to increase the stability of the support frame 41 supporting the shell 1.

[0047] In some embodiments, see Figure 5 The back surface 13 of the housing 1 is provided with a first receiving groove 131. Along the second direction Y, the projections of the plurality of second magnetic members 5 are all located in the first receiving groove 131. The second direction Y is perpendicular to the back surface 13 of the housing 1. Figure 5 and Figure 6 When the first fixing section 411 is magnetically attracted to the second magnetic component 5 closest to the AR mirror assembly 2, the support frame 41 is accommodated in the first accommodating groove 131, so that when the support frame 41 is no longer needed to support the shell 1, the shell 1 can be placed flat on the supporting plane, that is, the back side 13 of the shell 1 is supported on the supporting plane.

[0048] In some embodiments, see Figure 5 and Figure 6 The bottom wall of the first accommodating groove 131 is further provided with a second accommodating groove 1311. When the first fixing section 411 is magnetically attracted to the second magnetic component 5 closest to the AR mirror assembly 2, at least a portion of the connecting frame 42 can be accommodated in the second accommodating groove 1311, so as to reduce the risk of the supporting frame 41 protruding out of the first accommodating groove 131 along the second direction Y, thereby avoiding affecting the shell 1 from being placed flat on the load-bearing plane.

[0049] In some embodiments, see Figure 2 and Figure 5 The protective shell 100 also includes a limiting member 7, which is arranged on the bottom wall of the first accommodating groove 131. The first fixing section 411 is provided with a limiting groove 4111. When the first fixing section 411 is magnetically attracted to one of the first magnetic members 3 other than the one closest to the AR mirror assembly 2, the limiting member 7 is received in the limiting groove 4111 to limit the sliding of the first fixing section 411 along the bottom wall of the first accommodating groove 131, which is beneficial to improving the stability of the support of the support assembly 4 to the shell 1.

[0050] In some embodiments, see Figure 5 and Figure 6The protective case 100 further includes a third magnetic member 6, which is disposed on the bottom wall of the first receiving groove 131 and is located on the side of all the second magnetic members 5 facing away from the AR mirror assembly 2 along the first direction X. The support segment 412 is embedded with a magnetic member (not shown) or the support segment 412 includes a magnetic material. When the first fixing segment 411 is magnetically attracted to the second magnetic member 5 closest to the AR mirror assembly 2, the first fixing segment 411 and the support segment 412 are both accommodated in the first receiving groove 131, and the third magnetic member 6 is magnetically attracted to the support segment 412, thereby reducing the risk of the support segment 412 being separated from the first receiving groove 131.

[0051] In some embodiments, see Figure 5 The protective shell 100 also includes a covering member 8, which is accommodated in the first accommodating groove 131 and is bonded and fixed to the bottom wall of the first accommodating groove 131. Along the second direction Y, the covering member 8 covers the third magnetic member 6 and all the second magnetic members 5, thereby fixing the third magnetic member 6 and all the second magnetic members 5 to the shell 1, while preventing the third magnetic member 6 and each second magnetic member 5 from being exposed, which is beneficial to improving the aesthetics of the protective shell 100.

[0052] In an embodiment of the present invention, when the AR mirror assembly 2 needs to be used, the AR mirror assembly 2 can be adjusted to the first state. When the AR mirror assembly 2 is not needed, the AR mirror assembly 2 can be adjusted to the second state without removing the AR mirror assembly 2, thereby reducing the risk of losing the AR mirror assembly 2. In addition, by removably snapping one end of the connector 21 into the card slot 12, the AR mirror assembly 2 can also be removed for users who do not need to use the AR mirror assembly, thereby reducing the space occupied by the AR mirror assembly 2 and improving the aesthetics of the protective case 100.

[0053] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
