[0029] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0032] Electronic products such as mobile phones, tablets, and e-readers are often protected with protective cases, and in some usage environments, a stand is needed to support the product. However, existing protective cases and stands are separate, requiring the stand to be carried separately and assembled into the protective case when needed, which is inconvenient.

[0033] An embodiment of this application provides a protective shell, including a shell, an adjustment component, and a bracket. The shell has a recessed portion, which includes a receiving groove and a mounting groove. Along a first direction, the receiving groove communicates with the mounting groove. The adjustment component is disposed in the mounting groove and includes a base and a connector. The base is rotatably embedded in the mounting groove, and the connector is fixed to the base, allowing the connector to rotate together with the base around the axis of the base within the mounting groove. The bracket has a connecting end, which is rotatably connected to the connector, allowing the bracket to rotate relative to the connector towards or away from the shell. The bracket, connector, and base can rotate together around the axis of the base. When the bracket rotates around the axis of the base to the corresponding mounting groove, the bracket can be embedded in the recessed portion.

[0034] In this application, the housing is mounted on the product. When product support is not required, the housing houses the bracket via a recess, concealing the bracket and preventing it from protruding and affecting aesthetics or product usability. When product support is needed, the bracket is driven to rotate relative to the connector away from the housing to unfold, providing support for the product. Furthermore, the bracket can also be driven to rotate the connector and base together around the base's axis, changing the bracket's orientation and allowing it to support the product from multiple angles, or be used as a handle. Therefore, the protective housing includes a bracket, eliminating the need for a separate bracket and facilitating convenient product support at any time. The bracket supports the housing from multiple angles, making it suitable for various products and applications, demonstrating good versatility.

[0035] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0036] Please see Figure 1 This application provides a protective case 100 for use with product 200. Product 200 includes electronic products such as mobile phones, tablets, or e-readers.

[0037] Please combine Figure 1 and Figure 2 In some embodiments, the protective shell 100 includes a shell 10, an adjustment assembly 20, and a bracket 30. The shell 10 has a receiving cavity 111 to receive the product 200, thereby mounting the shell 10 onto the product 200. The adjustment assembly 20 is located on the side of the shell 10 facing away from the receiving cavity 111 and is connected to the bracket 30, so that the bracket 30 is connected to the shell 10, thus providing the protective shell 100 with the bracket 30 for convenient support of the product 200 at any time. The adjustment assembly 20 can drive the bracket 30 to rotate relative to the shell 10, thereby facilitating the support of the shell 10 from multiple angles.

[0038] Please see Figure 2 The housing 10 has a recess 13 disposed opposite to the receiving cavity 111. The recess 13 includes a receiving groove 131 and a mounting groove 132. Along a first direction X, the receiving groove 131 communicates with the mounting groove 132. In the illustrated embodiment, the first direction X is the width direction of the housing 10.

[0039] Please combine Figure 2 and Figure 3 The adjustment component 20 is disposed in the mounting groove 132. The adjustment component 20 includes a base 21 and a connector 22. The base 21 is rotatably embedded in the mounting groove 132, and the connector 22 is fixed to the base 21, so that the connector 22 can rotate together with the base 21 in the mounting groove 132 about the axis of the base 21.

[0040] The bracket 30 has a connecting end 311, which is rotatably connected to the connector 22, allowing the bracket 30 to rotate relative to the connector 22 toward or away from the housing 10 (see reference). Figure 4 It also allows the bracket 30, connector 22, and base 21 to rotate together around the axis of base 21 (see...). Figure 5 This allows the bracket 30 to support the product 200 from multiple angles.

[0041] Please see Figure 3When product 200 is not required to be supported, the bracket 30 is first driven to rotate, causing the bracket 30, connector 22, and base 21 to rotate together around the axis of base 21 until the bracket 30 corresponds to the recess 13. Then, the bracket 30 is driven to rotate relative to connector 22 toward housing 10, causing the end of the bracket 30 away from connector 311 to approach housing 10, until the bracket 30 is embedded in the recess 13. At this time, housing 10 can accommodate the bracket 30 through the recess 13, thus hiding the bracket 30 and preventing it from protruding from housing 10, which would affect aesthetics or the use of product 200.

[0042] Please see Figure 4 When product 200 needs support, the drive bracket 30 rotates relative to the connector 22 away from the housing 10 to unfold the bracket 30. The distance between the end of the bracket 30 away from the connector 311 and the housing 10 is adjustable, allowing the bracket 30 to support product 200. Please refer to [link to relevant documentation]. Figure 5 Furthermore, the drive bracket 30 can drive the connector 22 and the base 21 to rotate together around the axis of the base 21, thereby changing the orientation of the bracket 30 and allowing the bracket 30 to be adjusted to any angle, so that the bracket 30 can support the product 200 from multiple angles.

[0043] Therefore, the protective case 100 in this application has a bracket 30. The bracket 30 does not need to be carried separately and is convenient to use at any time to support the product 200. The bracket 30 can support the case 10 from multiple angles and can be used by different products 200 at multiple angles. It is suitable for various application scenarios of the product 200 and has good versatility.

[0044] Please see Figure 6 In some embodiments, the bracket 30 is elongated. First, unfold the bracket 30 and adjust the distance between the end of the bracket 30 away from the connecting end 311 and the housing 10; then drive the bracket 30 to rotate the connecting piece 22 and the base 21 together around the axis of the base 21 to change the orientation of the bracket 30; use the bracket 30 as a handle extending from the product 200, and the user holds the bracket 30 with four fingers to fix the position of the product 200. At this time, the user can hold the bracket 30 and use the product 200 to take pictures.

[0045] Please see Figure 7 In some embodiments, the housing 10 includes an inner shell 12 and an outer shell 11. A receiving cavity 111 is injection molded from the outer shell 11. The outer shell 11 has a through groove 112 extending along a second direction Z. A mounting groove 132 is provided in the inner shell 12, and the inner shell 12 is fixedly mounted to the outer shell 11, such that the through groove 112 and the inner shell 12 form a receiving groove 131. In the illustrated embodiment, the second direction Z is perpendicular to the first direction X, and the second direction Z is the thickness direction of the housing 10.

[0046] In some embodiments, the inner wall of the mounting groove 132 is provided with a plurality of arched portions 1323 at intervals. The plurality of arched portions 1323 are spaced apart and smoothly transition with the inner wall of the mounting groove 132. The outer wall of the base 21 is interference-fitted with the inner wall of the mounting groove 132, so that the base 21 rotates around its own axis in the mounting groove 132 under the action of external force.

[0047] By interfering with the inner wall of the mounting groove 132, the base 21 can be adjusted and kept in the adjusted position after the user adjusts the base 21 to rotate. This makes it convenient for the user to adjust the angle and position of the bracket 30 and prevents the base 21 from rotating freely when it is not under force, which would affect the use of the bracket 30.

[0048] Please see Figure 8 and Figure 9 In some embodiments, the inner shell 12 is provided with a stop surface 1322, which is located within the mounting groove 132. The stop surface 1322 is disposed facing the bottom surface 1321 of the mounting groove 132. The stop surface 1322 is configured to abut against the base 21, so that the bottom surface 1321 and the stop surface 1322 limit the base 21 within the mounting groove 132, thereby preventing the base 21 from moving in the second direction Z during rotation around the axis under force, which would cause the base 21 to detach or fall out of the mounting groove 132. For ease of description, the bottom surface 1321 of the mounting groove 132 will be referred to as the bottom surface 1321 in the following text.

[0049] In the illustrated embodiment, the stop surface 1322 and the bottom surface 1321 are spaced apart along the second direction Z, and the stop surface 1322 is parallel to the bottom surface 1321.

[0050] Please see Figure 8 and Figure 9 In some embodiments, the housing 11 is provided with a guide groove 113, which is located on the side of the housing 11 facing the bottom surface 1321. The base 21 is provided with a protrusion 211 on the side facing away from the bottom surface 1321, which is movably disposed in the guide groove 113. The guide groove 113 is configured to guide the base 21 to rotate about the axis of the base 21 within the mounting groove 132.

[0051] The guide groove 113 guides the base 21 to rotate around its own axis within the mounting groove 132, preventing the base 21 from shifting its position when it is subjected to force and rotates.

[0052] Please see Figure 10 In some embodiments, the protrusion 211 forms a non-closed annular protrusion 211 structure around the axis of the base 21 on the side of the base 21 facing away from the bottom surface 1321. The protrusion 211 structure forms a notch 212, which is configured to receive the support 30 when the support 30 is embedded in the recess 13.

[0053] By setting a notch 212 to avoid obstructing the bracket 30, the protrusion 211 structure is prevented from affecting the folding and storage of the bracket 30.

[0054] In some embodiments, the guide groove 113 is a non-closed annular guide groove structure. Along the second direction Z, the center of the guide groove 113 structure coincides with the center of the protrusion 211 structure, so that the guide groove 113 can guide the base 21 to rotate around the axis of the base 21 within the mounting groove 132. That is, the centers of the guide groove 113 structure and the protrusion 211 structure both fall on the axis, and the axis coincides with the extension line extending from the center along the second direction Z.

[0055] Please see Figure 11 In some embodiments, the connector 22 includes a chuck 223, and a locking block 2231 is fixedly provided on the outer wall of the chuck 223. The inner wall of the base 21 is provided with a locking groove 213. The locking block 2231 engages with the locking groove 213, so that the chuck 223 is held and fixed to the base 21.

[0056] The chuck 223 and the base 21 are connected by a locking block 2231 and a locking slot 213, so that the chuck 223 and the base 21 can rotate together around the axis of the base 21.

[0057] Please combine Figure 10 and Figure 12 In some embodiments, the connector 22 further includes a chuck 223, a fixing portion 221, and a connecting rod 222. The fixing portion 221 is partially sandwiched between the bottom surface 1321 and the chuck 223, so that the chuck 223 stops the fixing portion 221 in the mounting groove 132, thereby preventing the fixing portion 221 from moving in the second direction Z during rotation around the axis in the mounting groove 132 under force, which would cause the fixing portion 221 to detach or fall out of the mounting groove 132. The fixing portion 221 arches along the second direction Z toward the side opposite to the bottom surface 1321 to form a channel 2211. The arched portion 1323 of the fixing portion 221 passes through the chuck 223, so that the fixing portion 221 can drive the chuck 223 and the base 21 to rotate together around the axis of the base 21. The connecting rod 222 passes through the channel 2211, and the connecting end 311 of the bracket 30 is connected to the connecting rod 222, so that the bracket 30 can rotate relative to the fixed part 221 around the connecting rod 222, that is, the bracket 30 can rotate relative to the connecting member 22 towards or away from the housing 10; it also allows the bracket 30 to drive the fixed part 221, the chuck 223 and the base 21 to rotate together around the axis of the base 21 through the connecting rod 222.

[0058] In use, the user can control the bracket 30 to rotate around the connecting rod 222 or control the bracket 30 to rotate around the axis of the base 21 so that the bracket 30 can be adjusted to any position.

[0059] In some embodiments, when the connecting rod 222 is rotatably disposed within the channel 2211, the connecting end 311 of the bracket 30 is fixedly connected to the connecting rod 222. When the connecting rod 222 is fixed within the channel 2211 formed by the fixing part 221, the connecting end 311 of the bracket 30 is rotatably connected to the connecting rod 222.

[0060] In some embodiments, the connecting end 311 of the bracket 30 is provided with two sleeves 3111, which are fixedly sleeved on both ends of the connecting rod 222.

[0061] In some embodiments, the extension direction of the link 222 is defined as a third direction Y, which is perpendicular to the first direction X and the second direction Z. In the illustrated embodiment, the third direction Y is the length direction of the housing 10.

[0062] In some embodiments, when the connecting rod 222 is rotatably disposed within the channel 2211, the connecting rod 222 and the channel 2211 are interference-fitted, allowing the bracket 30 to rotate around the connecting rod 222 under the action of external force. Furthermore, the bracket 30 remains in the adjusted position after the user adjusts its rotation around the connecting rod 222, facilitating the user's adjustment of the angle and position of the bracket 30 and preventing the connecting rod 222 from rotating freely when not under force, thus affecting the use of the bracket 30. When the connecting rod 222 is fixedly disposed within the channel 2211, the sleeve 3111 and the connecting rod 222 are interference-fitted.

[0063] Please combine Figure 10 and Figure 11 In some embodiments, the connector 22 further includes a first pad 224 and a second pad 225. Both the first pad 224 and the second pad 225 are fixedly disposed on the side of the chuck 223 facing away from the bottom surface 1321. Along the first direction X, the first pad 224 and the second pad 225 are respectively disposed on both sides of the arched portion 1323 of the fixing portion 221 to avoid obstructing the arched portion 1323 of the fixing portion 221. Along the second direction Z, the thickness of the first pad 224 is greater than the thickness of the second pad 225.

[0064] Please see Figure 9 When the bracket 30 is embedded in the recessed part 13, the second pad 225 supports part of the bracket 30, and the first pad 224 is coplanar with the side of the bracket 30 facing away from the bottom surface 1321, preventing the bracket 30 from tilting or sinking, so that when the housing 10 stores the bracket 30, the protective shell 100 has an aesthetically pleasing appearance and does not affect the use of the product 200.

[0065] Please see Figure 12 In some embodiments, the support 30 includes a first frame 31 and a second frame 32. The first frame 31 is rotatably mounted on the connector 22. The second frame 32 is rotatably connected to the end of the first frame 31 away from the connector 22.

[0066] In some embodiments, both the first frame 31 and the second frame 32 are elongated.

[0067] Please see Figure 4 , Figure 5 , Figure 6 and Figure 11 By rotating and opening the second frame 32, the length of the first frame 31 can be increased, making it easier for the user to hold the bracket 30 and use the product 200 for shooting; the second frame 32 can also provide auxiliary support for the shell 10, so that the bracket 30 can more stably support the product 200 from multiple angles.

[0068] Please see Figure 12 In some embodiments, the first frame 31 is provided with a clearance groove 312, and a support rod 313 is provided within the clearance groove 312. The second frame 32 is provided with a connecting tube 321. The connecting tube 321 is sleeved on the support rod 313, allowing the second frame 32 to rotate relative to the first frame 31 around the support rod 313 to adjust the angle of the second frame 32. The clearance groove 312 is configured to accommodate the second frame 32 when it rotates toward the first frame 31, so as to fold the second frame 32 into the clearance groove 312, facilitating the storage of the first frame 31 when the second frame 32 is not needed.

[0069] In some embodiments, the extension direction of the support rod 313 is parallel to the connecting rod 222.

[0070] In some embodiments, a stop plate 3121 is provided in the clearance groove 312. When the second frame 32 is housed in the clearance groove 312, the stop plate 3121 supports the first frame 31 to prevent the first frame 31 from rotating in the opposite direction.

[0071] In some embodiments, the support rod 313 is interference-fitted with the inner wall of the connecting cylinder 321, so that the second frame 32 rotates around the support rod 313 under the action of external force. Furthermore, the second frame 32 remains in the adjusted position after the user adjusts the rotation around the support rod 313, which facilitates the user to adjust the angle and position of the second frame 32 and prevents the second frame 32 from rotating freely when it is not under force, thus affecting the use of the bracket 30.

[0072] In some embodiments, the end of the second frame 32 away from the connecting cylinder 321 is provided with an inclined surface, so that when the second frame 32 is stored in the clearance groove 312, there is a gap between the second frame 32 and the stop plate 3121, which makes it convenient for the user to unfold the second frame 32.

[0073] Please see Figure 3 and Figure 10In some embodiments, when the second frame 32 is housed in the clearance groove 312 and the bracket 30 is embedded in the recess 13, the second frame 32 extends out of the first frame 31 along the first direction X, and the length of the through groove 112 is greater than the length of the second frame 32 along the third direction Y, that is, there is a gap between the through groove 112 and the end of the bracket 30 away from the connection end 311, which makes it convenient for the user to unfold the first frame 31.

[0074] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
