[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0040] The present utility model embodiment provides a protective shell 1000, such as Figure 1-Figure 5As shown, the protective shell 1000 includes a shell 100, a connecting block 200, a supporting member 400, a positioning friction block 500 and a connecting belt 600. The back of the shell 100 is provided with one of the slot structure 320 and the plug-in structure 310, and the connecting block 200 is provided with the other of the slot structure 320 and the plug-in structure 310. The slot structure 320 and the plug-in structure 310 are in a first direction ( Figure 1 The connecting block 200 is plugged and matched in the X direction (in the X direction) so that the connecting block 200 is detachably connected to the housing 100. The supporting member 400 is rotatably connected to the connecting block 200 so that the supporting member 400 can rotate relative to the back of the housing 100 and support the back of the housing 100. The connecting block 200 includes a second direction ( Figure 1 The first surface 210 is perpendicular to the first direction (in the Y direction), and the second direction is perpendicular to the first direction. The positioning friction block 500 is installed on the first surface 210 to provide positioning friction when the slot structure 320 is plugged into the plug structure 310. The connecting belt 600 includes a first end 610 and a second end 620 that are oppositely arranged. The first end 610 is connected to the back of the housing 100, and the second end 620 is connected to the connecting block 200.

[0041] It should be noted that since the connecting block 200 can be removed from the back of the shell 100 and move relative to the shell 100, there is a problem of unclear reference to the second direction. In order to make the reference to the second direction clear, the second direction referred to in this embodiment is determined based on the state when the connecting block 200 is installed on the back of the shell 100.

[0042] By implementing this embodiment, when the user needs to watch a movie or TV series, the user can first rotate the bracket, and then place the protective shell 1000 on the desktop to use the bracket to support the mobile terminal. After use, you only need to rotate the bracket in the opposite direction to store the bracket, which is very convenient. Since the support member 400 is installed on the back of the shell 100 through the connecting block 200, and the connecting block 200 is detachably connected to the back of the shell 100 by the cooperation of the slot structure 320 and the plug-in structure 310, when the user needs wireless charging, or needs to install a radiator on the back of the mobile terminal, the connecting block 200 can be pulled out from the back of the shell 100, so that the bracket will be detached from the back of the shell 100, which will not affect the wireless charging efficiency and the installation of the radiator.

[0043] Since the slot structure 320 and the plug-in structure 310 are plugged in and matched in a first direction, and the positioning friction block 500 is installed in the second direction of the connecting block 200, which is inconsistent with the plug-in matching direction of the slot structure 320 and the plug-in structure 310, the positioning friction block 500 can be used to provide positioning friction when the slot structure 320 and the plug-in structure 310 are plugged in and matched, so that the plug-in structure 310 will not be easily detached from the slot structure 320, thereby improving the user experience and reducing the probability of losing the support member 400.

[0044] The connecting belt 600 includes a first end 610 and a second end 620 that are arranged opposite to each other, wherein the first end 610 is connected to the back of the housing 100, and the second end 620 is connected to the connecting block 200. In this way, even if the plug-in structure 310 is separated from the slot structure 320, the connecting block 200 and the supporting member 400 can still be connected to the back of the housing 100 through the connecting belt 600, effectively preventing the supporting member 400 from being lost.

[0045] refer to Figure 1 In a specific embodiment, the first direction is the length direction or the width direction of the shell 100 , the connecting block 200 includes a second surface 220 facing away from the first surface 210 , and the second end 620 is connected to the second surface 220 .

[0046] Specifically, the plug-in structure 310 and the slot structure 320 need to have a certain insertion depth to ensure sufficient insertion stability. If the first direction is the thickness direction of the housing 100, then either the insertion stability of the plug-in structure 310 and the slot structure 320 will be sacrificed, or the thickness of the protective shell 1000 will be relatively large. In order to make the protective shell 1000 thinner and the plug-in structure 310 and the slot structure 320 have sufficient insertion stability, the first direction in this embodiment is the length direction or width direction of the housing 100.

[0047] In addition, if the second end 620 and the positioning friction block 500 are arranged on the same surface of the connection block 200, the size of the connection block 200 needs to be increased to accommodate the second end 620 and the positioning friction block 500, which is not only not conducive to the miniaturization of the protective shell 1000, but also the huge connection block 200 will lead to a poor visual experience. Therefore, the second end 620 and the positioning friction block 500 of this embodiment are arranged on two opposite surfaces of the connection block 200, so that the two do not interfere with each other, the size of the connection block 200 can be made relatively small, and the visual experience is excellent.

[0048] refer to Figure 3 , Figure 5 In one embodiment, the plug-in structure 310 is disposed at the back of the housing 100. The plug-in structure 310 includes two plug-in blocks 311 disposed along a first direction. The two plug-in blocks 311 are disposed along a third direction ( Figure 3 The first end portion 610 is disposed between the two insert blocks 311, and the third direction is perpendicular to the first direction and the second direction.

[0049] By implementing this embodiment, when the connecting block 200 is installed on the back of the shell 100, the first end 610 is covered. Compared with the implementation method in which the first end 610 is exposed in the protective shell 1000, the aesthetics of the protective shell 1000 can be effectively improved.

[0050] refer to Figure 4 , Figure 7 In a specific embodiment, the slot structure 320 includes two contoured slots 321 respectively used in conjunction with the two plug blocks 311. A mounting groove 211 is also provided on the first surface 210. The mounting groove 211 is located between the two contoured slots 321. The positioning friction block 500 is installed in the mounting groove 211 so that the positioning friction block 500 is arranged opposite to the first end 610 in the second direction. In this way, the positioning friction block 500 can cooperate with the first end 610 to provide positioning friction force.

[0051] Specifically, the positioning friction block 500 of this embodiment is arranged between two contoured slots 321. Compared with the positioning friction block 500 arranged at other positions, the size of the connecting block 200 can be made smaller, and the visual experience is excellent. The purpose of setting the mounting slot 211 is to provide a clear installation position for the positioning friction block 500. When the mounting slot 211 is not set, the positioning friction block 500 is easy to be installed crooked, so that the positioning friction block 500 deviates from the preset installation position. If the deviation is too large, it may also cause insufficient positioning friction. In order to solve this technical problem, the present embodiment sets the mounting slot 211 between the two contoured slots 321, and sets the positioning friction block 500 at the mounting slot 211, so that the positioning friction block 500 can be prevented from being installed crooked.

[0052] refer to Figure 5 In one embodiment, a first abutting step is provided at a position adjacent to the end of the first end portion 610 and the end of the inserting block 311 , and the first abutting step 611 is used to abut against the connecting block 200 .

[0053] Specifically, when the plug block 311 is inserted into the slot structure 320, the position where it first enters the slot structure 320 is called the starting end, and the position where it last enters the slot structure 320 is called the end. If the connection block 200 can continue to move along the insertion direction after moving to the end of the plug block 311 and entering the slot structure 320, then each time the connection block 200 is installed, the insertion depth of the plug block 311 and the slot structure 320 will be different, so that it is difficult to position the connection block 200 at the optimal installation position, so that the plug block 311 is more likely to be separated from the slot structure 320.

[0054] In order to solve this technical problem, in the present embodiment, a first abutment step 611 is provided at a position adjacent to the first end portion 610 and the end of the plug block 311, so that after the connecting block 200 moves to the end of the plug block 311 and enters the slot structure 320, it will be blocked by the first abutment step 611. When the user installs the connecting block 200, he only needs to push the connecting block 200 until it abuts against the first abutment step 611. In this way, each time the connecting block 200 is installed, the connecting block 200 will be in the same position.

[0055] refer to Figure 8-Figure 12 In one embodiment, the back of the housing 100 is provided with two protrusions 330 extending in the first direction, and the two protrusions 330 are extended in the third direction ( Fig.10 The first end portion 610 is disposed between the two protrusions 330, and the third direction is perpendicular to the second direction.

[0056] By implementing this embodiment, when the connecting block 200 is installed on the back of the shell 100, the first end 610 is covered. Compared with the implementation method in which the first end 610 is exposed in the protective shell 1000, the aesthetics of the protective shell 1000 can be effectively improved.

[0057] refer to Fig.12 In a specific embodiment, a second abutting step 612 is provided at a position of the first end portion 610 adjacent to the end of the slot structure 320 , and the second abutting step 612 is used to abut against the plug-in structure 310 .

[0058] Specifically, when the plug-in structure 310 is inserted into the slot structure 320, it will first enter the starting end of the slot structure 320 and then gradually move to the end of the slot structure 320. If the connection block 200 can continue to move along the insertion direction after the plug-in structure 310 enters the end of the slot structure 320, then each time the connection block 200 is installed, the insertion depth of the plug-in structure 310 and the slot structure 320 will be different, so that the connection block 200 is difficult to be positioned at the optimal installation position, so that the plug-in block 311 is more likely to be separated from the slot structure 320.

[0059] In order to solve this technical problem, in the present embodiment, a second abutment step 612 is provided at a position adjacent to the end of the first end 610 and the slot structure 320, so that after the connecting block 200 moves to the end where the plug-in structure 310 enters the slot structure 320, it will be blocked by the second abutment step 612. When the user installs the connecting block 200, he only needs to push the connecting block 200 until it abuts against the second abutment step 612. In this way, each time the connecting block 200 is installed, the connecting block 200 will be in the same position.

[0060] refer to Figure 1 In one embodiment, a side of the second end portion 620 facing away from the first surface 210 is provided with an anti-slip protrusion 621 .

[0061] Specifically, the anti-skid protrusion 621 can increase the friction when the user pushes out the connection block 200, making it easier for the user to apply force to push out the connection block 200, and providing a better user experience. The anti-skid protrusion 621 has many specific shapes, such as convex strips and convex dots; therefore, this embodiment is not limited here.

[0062] In one embodiment, a first magnetic ring (not shown in the figure) is installed on the support member 400, and a second magnetic ring (not shown in the figure) is installed on the back of the housing 100, and the first magnetic ring attracts the second magnetic ring.

[0063] By implementing this embodiment, the support member 400 can be adsorbed to the back of the shell 100 by the second magnetic ring when stored, so as to prevent the support member 400 from being rotated and opened due to external force. In addition, since the connecting block 200 is connected to the support member 400, after the support member 400 is adsorbed to the second magnetic ring, the plug-in stability between the slot structure 320 and the plug-in structure 310 will be higher, and the plug-in structure 310 will not easily detach from the slot structure 320.

[0064] refer to Figure 1 , Figure 8 In one embodiment, the first direction is the length direction of the shell 100 , and the connecting belt 600 further includes a connecting portion 630 , which is connected between the first end 610 and the second end 620 , and the connecting portion 630 protrudes from the bottom of the shell 100 .

[0065] By implementing this embodiment, when the user holds the mobile terminal with one hand, he needs to hold both sides of the mobile terminal. If the connection portion 630 protrudes from the side of the housing 100, it will affect the comfort of holding. In this embodiment, the connection portion 630 protrudes from the bottom, so when the user holds the mobile terminal with one hand, he will not be disturbed by the connection belt 600, or the interference of the connection belt 600 is relatively small, so the user experience is better.

[0066] It is worth mentioning that the connection portion 630 protrudes from the bottom of the housing 100 means that the connection portion 630 protrudes from the bottom of the housing 100 in a natural state. The connection portion 630 protrudes from the bottom of the housing 100, so that the connection portion 630 has a sufficient length for the user to pass part of the fingers through the accommodating space defined by the connection portion 600 when holding the mobile terminal, so that even if the mobile terminal is not held firmly, it will not fall from the user's hand.

[0067] refer to Figure 6 , Fig.13In one embodiment, a hard pin 640 is disposed on a side of the second end portion 620 facing the second surface 220 , and a plug hole 221 is disposed on the second surface 220 , and the hard pin 640 is installed in the plug hole 221 .

[0068] Specifically, since the hard plug 640 is hard in texture, it can cooperate with the plug hole 221 to increase the connection stability between the second end 620 and the connection block 200 .

[0069] refer to Figure 3 , Figure 5 In one embodiment, the housing 100 includes a housing body 110 and a mounting block 120 mounted on the back of the housing body 110, one of the slot structure 320 and the plug-in structure 310 is disposed on the mounting block 120, and the first end 610 is also connected to the mounting block 120. Optionally, the housing body 110 and the mounting block 120 may be integrally formed, or may be separately formed and then assembled together, which is not limited in the present invention.

[0070] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
