[0036] This application provides a protective shell assembly; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3The protective housing assembly includes a protective housing 10 and a bracket 20.

[0037] The protective case 10 includes a back panel 11 for housing electronic devices.

[0038] Understandably, electronic devices can be tablets, mobile phones, etc.

[0039] The bracket 20 includes a folding part 21 and a support part 22 that are rotatably connected.

[0040] The support portion 22 is used to support the back plate 11, and the support plate and the back plate 11 are rotatable relative to each other in the plane where the back plate 11 is located. In this way, by causing relative rotation between the support plate and the back plate 11, the placement position of the back plate 11 on the support portion 22 can be adjusted, thereby adjusting the placement position of the electronic device.

[0041] It should be noted that "placement position" refers to the orientation of the electronic device and / or backplate 11 relative to the support surface of the supported object, within the plane of the backplate 11. For example, relative to the support surface of the supported object, the electronic device and / or backplate 11 is positioned laterally (e.g., horizontally) within the plane of the backplate 11. Figure 2 As shown), vertical (as shown) Figure 1 (as shown) or placed at an angle.

[0042] The specific type of the supporting object is not limited, as long as it can provide support. For example, the supporting object can be a table, windowsill, or the ground.

[0043] The plane containing the back plate 11 refers to any cross-section of the back plate 11 along the thickness direction.

[0044] The folding part 21 can be flipped about the axis of rotation defined by it and the support part 22, in a direction closer to or away from the back plate 11.

[0045] Please see Figure 1 and Figure 2 The bracket 20 has an unfolded state. In the unfolded state, the end of the folding part 21 away from the rotation axis and the end of the support part 22 away from the rotation axis are placed on the support surface of the supported object to support the protective shell 10. In the unfolded state, the folding part 21, the support part 22, and the support surface of the supported object form a stable triangular support, allowing the support part 22 to provide relatively stable support for the back plate 11, thereby providing support for the protective shell 10. Moreover, by adjusting the flip angle of the folding part 21, the included angle between the folding part 21 and the support part 22, and the included angle between the support part 22 and the support surface, can be adjusted, thereby adjusting the tilt angle of the support part 22 relative to the support surface to a certain extent. In this way, the tilt angle of the protective shell 10 relative to the support surface can also be adjusted, that is, the tilt angle of the electronic device relative to the support surface can be adjusted.

[0046] The protective case assembly provided in this application embodiment can, on the one hand, change the placement position of the electronic device by rotating the support part 22 relative to the back plate 11 in the plane where the back plate 11 is located, and on the other hand, adjust the tilt angle of the electronic device relative to the support surface by flipping the folding part 21 around the rotation axis defined by it and the support part 22, so that the placement position and tilt angle of the electronic device can meet more placement requirements of the user.

[0047] For example, the support portion 22 is plate-shaped, and in the unfolded state, the support portion 22 and the back plate 11 are stacked together along the thickness direction of the back plate 11. In this way, the support portion 22 supports the back plate 11.

[0048] For example, the folding part 21 is plate-shaped, and the bracket 20 has a folded state, such as... Figure 3 As shown, in the stowed state, the support portion 22 and the folding portion 21 are laid flat on the surface of the back panel 11. This helps to reduce the space occupied by the protective case assembly in the thickness direction when the bracket 20 is stowed, and helps to increase the portability of the protective case assembly.

[0049] It is understandable that the way the folding part 21 and the support part 22 are rotatably connected is not limited.

[0050] For example, the bracket 20 includes a hinge 24, and the folding portion 21 and the support portion 22 are rotatably connected by the hinge 24.

[0051] In other embodiments, the folding portion 21 and the support portion 22 can also be rotatably connected by a damping shaft.

[0052] In some embodiments, please refer to Figure 1 and Figure 2 The protective shell 10 includes an annular portion 12 fixed to the back plate 11. (See also...) Figure 5 The support portion 22 has an arc-shaped groove 221 formed on the side facing the back plate 11, and the annular portion 12 is accommodated in the arc-shaped groove 221, allowing the annular portion 12 to rotate within the arc-shaped groove 221. That is, the annular portion 12 and the arc-shaped groove 221 can rotate relative to each other, thereby achieving relative rotation between the back plate 11 and the support portion 22. In this embodiment, the arc-shaped groove 221 has a guiding function.

[0053] For example, the annular portion 12 and the back plate 11 can be an integral structure.

[0054] In some embodiments, such as Figure 9 As shown, the annular portion 12 has a plurality of positioning grooves 121, which are arranged circumferentially along the annular portion 12. Figure 5As shown, the bracket 20 includes an elastic positioning structure 23 disposed on the support portion 22. The elastic positioning structure 23 is capable of elastic deformation along the radial direction of the annular portion 12, and the end of the elastic positioning structure 23 can extend into or retract from the positioning groove 121 under its own elastic force. The elastic positioning structure 23 extends into the positioning groove 121 to hold the annular portion 12 in its current rotational position.

[0055] The end of the elastic positioning structure 23 can exit the positioning groove 121 under its own elastic force. This means that when the user rotates the annular part 12 or the support part 22, the annular part 12 and the support part 22 rotate relative to each other. The positioning groove 121 can squeeze the elastic positioning structure 23, causing the elastic positioning structure 23 to be compressed and exit the positioning groove 121. In other words, the elastic positioning structure 23 can play a certain degree of limiting role in the positioning groove 121, but it will not completely prevent the positioning groove 121 from rotating.

[0056] During the relative rotation of the annular portion 12 and the support portion 22, the elastic positioning structure 23 extends into different positioning grooves 121, causing the annular portion 12 to rotate at different angles relative to the support portion 22, thereby changing the placement position of the back plate 11. Furthermore, during the relative rotation of the annular portion 12 and the support portion 22, the elastic positioning structure 23 reciprocates against the annular portion 12 under its own elastic force to produce sound.

[0057] It is understandable that the shape of the positioning groove 121 is not limited, as long as it can compress the elastic positioning structure 23 during rotation.

[0058] For example, please refer to Figure 9 The outer peripheral surface of the annular portion 12 has a plurality of teeth 122 arranged in the circumferential direction, and a positioning groove 121 is formed between two adjacent teeth 122.

[0059] In some embodiments, such as Figure 5 As shown, the support portion 22 has a receiving groove 222, which is located radially outside the arcuate groove 221 and communicates with it. A portion of the elastic positioning structure 23 is located within the receiving groove 222, and the end of the elastic positioning structure 23 is located in the arcuate groove 221 and abuts against the annular portion 12. The receiving groove 222 is used to install the elastic positioning structure 23 and to guide and position the elastic positioning structure 23 along its deformation direction.

[0060] In some embodiments, please refer to Figure 4 and Figure 10 The support portion 22 is provided with a first notch 223. The protective shell assembly includes a cover portion 30, which covers the first notch 223.

[0061] For example, such as Figure 6As shown, the cover 30 includes a disc 31 and a flange 32 connected to each other. The disc 31 extends into the radially inner side of the annular portion 12 and is radially interference-fitted with the annular portion 12, so that the disc 31 can be relatively stably fixed to the back side of the back plate 11, thereby enabling the cover 30 to stably cover the first notch 223.

[0062] like Figure 10 As shown, the flange 32 is located on the side of the support portion 22 away from the back plate 11. That is, the support portion 22 is located between the flange 32 and the back plate 11 along the thickness direction of the back plate 11. The flange 32 is used to limit the support portion 22 along the thickness direction of the back plate 11, so that the support portion 22 will not detach from the annular portion 12 along the thickness direction of the back plate 11 during the relative rotation of the support portion 22 and the annular portion 12.

[0063] In some embodiments, please refer to Figure 5 The arc-shaped groove 221 includes a first groove wall 2211 and a second groove wall 2212 that are connected to each other. The first groove wall 2211 is radially positioned and fitted with the outer peripheral surface of the annular portion 12, and the second groove wall 2212 is located on the side of the first groove wall 2211 away from the back plate 11.

[0064] In this embodiment, a first notch 223 is formed in the radially inner space of the second groove wall 2212. The first notch 223 is used for the disc portion 31 to pass through and engage with the annular portion 12. The flange 32 is located on the side of the second groove wall 2212 away from the back plate 11, so that the second groove wall 2212 is located between the back plate 11 and the flange 32 along the thickness direction of the back plate 11.

[0065] In this embodiment, please refer to Figure 10 The outer periphery of the disk portion 31, the first groove wall 2211, and the second groove wall 2212 together form an annular groove 50, and a portion of the annular portion 12 is disposed within the annular groove 50. During the relative rotation of the support portion 22 and the annular portion 12, due to the interference fit between the disk portion 31 and the annular portion 12, the arc-shaped groove 221 rotates relative to the disk portion 31 and the annular portion 12. That is, during the rotation of the arc-shaped groove 221, the annular groove 50 is formed at different positions of the first groove wall 2211, the second groove wall 2212, and the outer periphery of the disk portion 31.

[0066] For example, please combine Figure 9 and Figure 10 The outer periphery of the disc portion 31 has a locking groove 311, and the inner peripheral wall of the annular portion 12 has a locking protrusion 123, which extends into the locking groove 311. This achieves circumferential positioning of the disc portion 31 and the annular portion 12, preventing relative rotation between them and helping to improve the structural stability of the protective shell assembly.

[0067] In some other embodiments, the outer periphery of the disk portion 31 may have a snap-fit ​​protrusion, and the inner peripheral wall of the annular portion 12 may have a snap-fit ​​groove, with the snap-fit ​​protrusion extending into the snap-fit ​​groove.

[0068] In the embodiment where the bracket 20 is in its stowed state, and the support portion 22 and the folding portion 21 are laid flat on the surface of the back plate 11, the folding portion 21 has a second notch 211. The first notch 223 and the second notch 211 together form a mounting hole 20a, and the disc portion 31 is located within the mounting hole 20a. That is, the mounting hole 20a allows the disc portion 31 to pass through to engage with the annular portion 12.

[0069] It should be noted that in this embodiment, when the bracket 20 needs to switch between a stowed state and a folded state, the folding portion 21 must not interfere with the annular portion 12 or the cover portion 30. That is, the inner wall 21a of the second notch 211 is located radially outside the cover portion 30 and the annular portion 12. In this way, the second notch 211 avoids the cover portion 30 and the annular portion 12, so that in the stowed state, the folding portion 21 can be laid flat with the support portion 22, and it is convenient for the folding portion 21 to switch between different states of the bracket 20.

[0070] In some embodiments, the protective shell assembly includes a first magnetic chuck 40 and a second magnetic chuck. The first magnetic chuck 40 is disposed on the support portion 22, and the second magnetic chuck is disposed on the back plate 11. The first magnetic chuck 40 and the second magnetic chuck are magnetically attracted to each other. In the unfolded state, the action of the first magnetic chuck 40 and the second magnetic chuck allows the back plate 11 to be stably connected to the support portion 22. When it is necessary to change the placement position of the back plate 11, it is only necessary to apply force to separate the first magnetic chuck 40 and the second magnetic chuck while simultaneously rotating the support portion 22 relative to the back plate 11, which is convenient to operate.

[0071] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0072] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
