[0040] 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.

[0041] The present utility model embodiment provides a protective shell 1000, such as Figure 1-Figure 9 As shown, the protective shell 1000 includes a shell 100, a connecting belt 200, a first connecting component 300 and a supporting member 400. The connecting belt 200 is made of a flexible material, and the connecting belt 200 includes a first end 210 and a second end 220 arranged opposite to each other, and the first end 210 is connected to the shell 100. The first connecting component 300 is detachably mounted on the back side 110 of the shell 100, and the first connecting component 300 includes a first hard connecting block 310 and a second hard connecting block 320 connected to each other, and the second end 220 is sandwiched between the first hard connecting block 310 and the second hard connecting block 320. The supporting member 400 is rotatably connected to the first connecting component 300, so that the supporting member 400 can rotate relative to the back side 110 of the shell 100 and support the back side 110 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 support member 400 and then place the protective case 1000 on the desktop to support the mobile terminal using the support member 400. After use, the support member 400 can be stored by simply rotating the support member 400 in the opposite direction, which is very convenient.

[0043] Since the support member 400 is installed on the back side 110 of the shell 100 through the first connecting component 300, and the first connecting component 300 is detachably connected to the back side 110 of the shell 100, when the user needs wireless charging, or needs to install a radiator on the back side 110 of the mobile terminal, the first connecting component 300 can be removed from the back side 110 of the shell 100, so that the support member 400 will be detached from the back side 110 of the shell 100, which will not affect the wireless charging efficiency and the installation of the radiator.

[0044] Furthermore, since the protective shell 1000 is provided with a connecting belt 200, the connecting belt 200 includes a first end 210 and a second end 220 that are relatively arranged, the first end 210 is connected to the shell 100, and the second end 220 is connected to the first connecting component 300. Therefore, even if the first connecting component 300 is removed from the back side 110 of the shell 100, the first connecting component 300 and the support member 400 are still connected to the shell 100 and will not be lost.

[0045] Specifically, the first connecting component 300 of the present embodiment includes a first hard connecting block 310 and a second hard connecting block 320 which are connected to each other. The second end 220 of the connecting belt 200 is clamped between the first hard connecting block 310 and the second hard connecting block 320. The difference between this technical solution and the prior art is that this technical solution does not require a metal sheet to be set inside the second end 220. Therefore, when the user pulls the connecting belt 200, the interior of the connecting belt 200 will not be irreversibly damaged by the metal sheet, thereby effectively extending the service life of the connecting belt 200.

[0046] refer to Figure 8 , Fig. 9 In a specific embodiment, the first hard connection block 310 is provided with one of the first protrusion 311 or the first recess 221 on one side facing the second end 220, and the second end 220 is provided with the other of the first protrusion 311 and the first recess 221 on one side facing the first hard connection block 310, and the first protrusion 311 is accommodated in the first recess 221. In this way, the first protrusion 311 and the first recess 221 can be used to increase the connection stability between the first hard connection block 310 and the second end 220.

[0047] In some embodiments, the second hard connection block 320 is provided with one of a second protrusion (not shown in the figure) or a second recess (not shown in the figure) on one side facing the second end 220, and the second end 220 is provided with the other of the second protrusion and the second recess on one side facing the second hard connection block 320, and the second protrusion is accommodated in the second recess. In this arrangement, the second protrusion and the second recess can be used to increase the connection stability between the second hard connection block 320 and the second end 220.

[0048] refer to Fig.10 In some embodiments, a slot 111 is provided on the back side 110 of the housing 100 for inserting the first connecting component 300 .

[0049] The present embodiment demonstrates a specific implementation method in which the first connecting component 300 is detachably mounted on the back side 110 of the shell 100. Specifically, when one wants to remove the first connecting component 300 from the back side 110 of the shell 100, the first connecting component 300 can be pulled out of the slot 111. When one wants to install the first connecting component 300 back to the back side 110 of the shell 100, one only needs to insert the first connecting component 300 into the slot 111, which is very convenient.

[0050] In some embodiments, the first connecting component 300 is detachably connected to the back surface 110 of the housing 100 by means of magnetic attraction. Specifically, when the first connecting component 300 is to be removed from the back surface 110 of the housing 100, it is only necessary to apply a force to the first connecting component 300 away from the back surface 110 of the housing 100; when the first connecting component 300 is to be installed back to the back surface 110 of the housing 100, it is only necessary to place the first connecting component 300 on the back surface 110 of the housing 100, and the first connecting component 300 will be adsorbed on the back surface 110 of the housing 100 under the action of the magnetic attraction, which is very convenient.

[0051] refer to Figure 5 , Fig.10 In some embodiments, one of the elastic block 112 and the slot 321 is disposed on the slot wall 1111 of the slot 111 , and the other of the elastic block 112 and the slot 321 is correspondingly disposed on the first connecting component 300 .

[0052] By implementing this embodiment, after the first connecting component 300 is inserted into the slot 111, the elastic card block 112 can be locked in the card slot 321, so that the first connecting component 300 will be constrained by the elastic card block 112 and the card slot 321, and the first connecting component 300 can be more stably accommodated in the slot 111, and will not be easily detached from the slot 111 due to external forces, providing an excellent user experience.

[0053] refer to Fig.11 In a specific embodiment, the elastic card block 112 includes two side walls 1121 arranged opposite to each other in the direction of the notch 1112 of the insertion slot 111 , and the two side walls 1121 gradually approach each other in the direction from the elastic card block 112 toward the bottom of the card slot 321 .

[0054] Specifically, when the first connecting component 300 enters the slot 111, one of the side walls 1121 of the elastic card block 112 will be squeezed, and because the two side walls 1121 gradually approach each other in the direction of the elastic card block 112 toward the bottom of the slot 321, as long as the first connecting component 300 is provided with enough force to deform and store energy for the elastic card block 112, the elastic card block 112 will be subjected to force, deform and store energy, so that the first connecting component 300 can smoothly enter the slot 111; when the first connecting component 300 is pulled out of the slot 111, the other side wall 1121 of the elastic card block 112 will be squeezed, and because the two side walls 1121 gradually approach each other in the direction of the elastic card block 112 toward the bottom of the slot 321, as long as the first connecting component 300 is provided with enough force to deform and store energy for the elastic card block 112, the elastic card block 112 will be subjected to force, deform and store energy, so that the first connecting component 300 can smoothly detach from the slot 111.

[0055] refer to Figure 5In some embodiments, two elastic card blocks 112 are provided, and the two elastic card blocks 112 are symmetrically arranged on both sides of the slot 111. Two card slots 321 are correspondingly provided. In this way, the first connecting component 300 can be more stably accommodated in the slot 111.

[0056] refer to Fig.12 In some embodiments, the back side 110 of the housing 100 is provided with a second connection assembly 600, the second connection assembly 600 includes a third hard connection block 610 and a fourth hard connection block 620 connected to each other, and the first end 210 is sandwiched between the third hard connection block 610 and the fourth hard connection block 620. In this way, the first end 210 of the connection belt 200 is not easily damaged when subjected to force, which effectively prolongs the service life of the connection belt 200.

[0057] refer to Figure 4 , Fig.10 , Fig.11 In some embodiments, the slot 111 is arranged on the third hard connection block 610, and the third hard connection block 610 is provided with a mounting groove 611 on one side close to the front side of the shell 100, and an opening 11111 connected to the mounting groove 611 is provided on the slot wall 1111 of the slot 111, and the elastic card block 112 includes a mounting portion 1122 and a clamping portion 1123, the mounting portion 1122 is limitedly arranged in the mounting groove 611, and the clamping portion 1123 is inserted into the slot 111 through the opening 11111, and the two side walls 1121 of the elastic card block 112 are both arranged on the clamping portion 1123.

[0058] In some embodiments, the elastic block 112 is a sphere or a hemisphere, and a spring is provided on the side of the elastic block 112 facing away from the slot, so that when the slot 321 moves to a position opposite to the elastic block 112, the elastic block 112 will be inserted into the slot 321 under the action of the spring.

[0059] refer to Figure 6 , Figure 7 In some embodiments, a positioning friction block 240 is provided on the slot wall 1111 of the slot 111, and the positioning friction block 240 is used to abut against the first connecting component 300. In this way, after the first connecting component 300 is inserted into the slot 111, it will contact the positioning friction block 240, and the positioning friction block 240 can provide positioning friction for the first connecting component 300, so that the first connecting component 300 can be more stably accommodated in the slot 111, and will not be easily separated from the slot 111 due to external forces, and the user experience is excellent.

[0060] refer to Figure 7 In a specific embodiment, the positioning friction block 240 is integrally formed with the first end portion 210. This can reduce the number of parts, thereby effectively reducing assembly costs and production costs.

[0061] refer to Figure 8 , Fig. 9 In some embodiments, the first connecting component 300 includes a screw (not shown in the figure), and the first hard connecting block 310 is provided with an internal thread column 312 on the side facing the second hard connecting block 320, and the internal thread column 312 is penetrated through the second end 220. The second hard connecting block 320 is provided with an internal thread column 312 on one side, and the internal thread column 312 is penetrated through the second end 220. The second hard connecting block 320 is provided with a mounting hole 322, and the screw is penetrated through the mounting hole 322 and the internal thread column 312 to fix the first hard connecting block 310 and the second hard connecting block 320.

[0062] Threaded connection can provide reliable connection strength, and has a relatively simple structure and relatively low cost, so the first hard connection block 310 and the second hard connection block 320 in this embodiment are connected together by screws. In some embodiments, the connection method of the third hard connection block 610 and the fourth hard connection block 620 is the same as the connection method of the first hard connection block 310 and the second hard connection block 320 in this embodiment, so this embodiment will not be repeated here.

[0063] refer to Figure 8 , Fig. 9 In order to increase the connection stability between the first hard connection block 310 and the second hard connection block 320, in a specific embodiment, four internal threaded columns 312 are provided, and the four internal threaded columns 312 are arranged in a matrix on the side of the first hard connection block 310 facing the second hard connection block 320, and four mounting holes 322 are provided corresponding to the screws.

[0064] refer to Figure 6 In some embodiments, the orientation of the notch 1112 of the slot 111 (see Figure 6 The X direction in the case 100) and the thickness direction in the case 100 (reference Figure 6 The slot 111 has a through hole 1113 at its bottom for the connecting belt 200 to pass through.

[0065] Specifically, the first connection component 300 and the slot 111 need to have a certain insertion depth to ensure sufficient insertion stability. If the notch 1112 of the slot 111 is oriented in the thickness direction of the housing 100, the thickness of the housing 100 will be relatively large, and the user experience will be poor. In order to make the housing 100 thinner, the notch 1112 of the slot 111 in this embodiment is oriented perpendicular to the thickness direction of the housing 100.

[0066] refer to Fig.10In some embodiments, the through opening 1113 includes a first area 11131 and a second area 11132, wherein the first area 11131 is located on a side of the second area 11132 close to the front surface of the housing 100. The position where the connecting belt 200 is adjacent to the second end 220 is passed through the second area 11132, and a stop step 230 is provided at the position where the connecting belt 200 is adjacent to the first end 210. The stop step 230 is blocked at the first area 11131, and the stop step 230 is used to stop the first connecting component 300.

[0067] Specifically, when the first connection component 300 is inserted into the slot 111, the position where it first enters the slot 111 is called the starting end, and the position where it last enters the slot 111 is called the end. If the first connection component 300 can continue to move along the insertion direction after it moves to the end of the first connection component 300 and enters the slot 111, then each time the first connection component 300 is installed, the insertion depth of the first connection component 300 and the slot 111 will be different, so that it is difficult to position the first connection component 300 at the optimal installation position.

[0068] In order to solve this technical problem, in this embodiment, a stop step 230 is provided adjacent to the first end 210 of the connecting belt 200, and the stop step 230 is provided at the first area 11131. The stop step 230 is used to stop the first connecting component 300. In this way, after the first connecting component 300 moves to the end of the first connecting component 300 and enters the slot 111, it will be stopped by the stop step 230. When installing the first connecting component 300, the user only needs to push the first connecting component 300 until it abuts against the stop step 230. In this way, each time the first connecting component 300 is installed, the first connecting component 300 will be in the same position.

[0069] refer to Figure 3 In some embodiments, a first magnetic ring 500 is mounted on the support member 400 , and a second magnetic ring (not shown) is disposed on the back side 110 of the housing 100 , and the first magnetic ring 500 attracts the second magnetic ring.

[0070] By implementing this embodiment, the support member 400 can be adsorbed to the surface 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 first connecting component 300 is connected to the support member 400, after the support member 400 is adsorbed to the second magnetic ring, the connection stability between the first connecting component 300 and the shell 100 will be stronger, and it will not be easily separated from the shell 100 due to external force, and the user experience is excellent.

[0071] 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.
