Utility Model Content

[0003] In view of this, the present application aims to provide a protective case component that can support both a tablet and a mobile phone, making it easier for users to browse content on their mobile phones while using a tablet, thereby improving user work efficiency and user comfort.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] This application provides a protective shell assembly, including:

[0006] A protective case includes a back plate and a support plate. The support plate supports the back plate. The back plate includes a folding portion, a first pivot, and a connecting portion.

[0007] A bracket is disposed on the back side of the folding portion, and the bracket is disposed between the lens hole and the first rotating shaft along a first direction, wherein the first direction intersects the extending direction of the first rotating shaft;

[0008] The bracket can extend and retract relative to the folding portion. In the retracted state, the bracket is located entirely on the back side of the folding portion. In the extended state, one end of the bracket extends toward one side of the folding portion for placing a mobile terminal.

[0009] In some embodiments, the support includes a first support and a second support, and the first support and the second support are rotatably connected. The first support includes a plurality of first sub-parts connected in sequence, and two adjacent first sub-parts are rotatably connected.

[0010] In the stored state, the plurality of first sub-parts are laid flat along the extension direction of the first rotating shaft, the second bracket extends along the extension direction of the first rotating shaft, the first sub-parts include opposing first surfaces and second surfaces, the second bracket is stacked on the first surfaces of the plurality of first sub-parts, and the second surfaces of the plurality of first sub-parts are connected to the folding portion.

[0011] In the extended state, the plurality of first sub-parts include a first part and a second part, the second surface of the second part is connected to the folding part, the first part is flipped onto the first surface of the second part, and is laid flat with the second bracket along the extension direction of the first pivot axis, so that the end of the second bracket away from the first bracket extends from one side of the periphery of the folding part for placing a mobile terminal.

[0012] In some embodiments, a flexible connection is formed at the junction of two adjacent first sub-parts to enable a rotatable connection between the two adjacent first sub-parts; and / or, the bracket includes a first hinge through which two adjacent first sub-parts are rotatably connected.

[0013] In some embodiments, the bracket includes a second hinge, the second bracket being a rigid member, and the first bracket and the second bracket are rotatably connected by the hinge.

[0014] In some embodiments, the second hinge includes a first leaf, a second leaf, and a second pivot connecting the first leaf and the second leaf, wherein the first leaf is bonded to the first bracket, and the second leaf is bonded to the second bracket.

[0015] In some embodiments, the first sub-part includes a first magnetic attraction component. In the retracted state, the first magnetic attraction component is used to magnetically engage with the folding portion and also to magnetically engage with the second bracket. In the extended state, the first magnetic attraction components of the two overlapping first sub-parts magnetically engage, and the second bracket magnetically engages with the first magnetic attraction component of the first sub-part of the second part and / or the folding portion.

That is, the protective case assembly can support both the tablet and the mobile phone at the same time, making it easier for users to browse content on the mobile terminal while using the tablet, which helps to improve user work efficiency and user comfort.

[0022] Furthermore, the bracket is positioned between the lens hole and the first pivot, which means that the bracket can be located in a relatively central position on the back side of the folding part 213 along the first direction. This allows the weight borne by the bracket to be mainly concentrated in the relatively central position of the folding part. In other words, the center of gravity of the protective case assembly will not be excessively raised, which helps to reduce the probability of the phone tipping over when placed on the back panel of the bracket. This helps to improve the stability of the phone when placed on the bracket, and thus improves the stability of the entire protective case assembly. Attached Figure Description

[0035] Please see Figures 1 to 5 This application provides a protective shell assembly, which includes a protective shell 20 and a bracket 10.

[0036] The protective shell 20 includes a back plate 21 and a support plate 22. The support plate 22 supports the back plate 21. The back plate 21 includes a folding portion 213, a first rotating shaft 212, and a connecting portion 211. The connecting portion 211 is connected to the support plate 22. The folding portion 213 is located on the side of the connecting portion 211 away from the support plate 22. The folding portion 213 is rotatably connected to the connecting portion 211 via the first rotating shaft 212. The folding portion 213 is used to place electronic devices. The rotatable connection between the folding portion 213 and the connecting portion 211 means that the angle between the folding portion 213 and the connecting portion 211 is adjustable. When the electronic device is placed in the folding portion 213, the angle between the folding portion 213 and the connecting portion 211 can be adjusted by rotating the folding portion 213, thereby changing the placement angle of the electronic device. At this time, the projection of the cross-section of the electronic device, the connecting portion 211, and the support plate 22 along the extension direction perpendicular to the first rotating shaft 212 forms a triangle, which helps to stably place the electronic device in the folding portion 213.

[0037] In some embodiments, the folding portion 213 is formed with a lens aperture 2131. The lens aperture 2131 is used to expose the lens of the electronic device, enabling the lens to sense ambient light and acquire images based on the sensed ambient light.

[0038] In some embodiments, the bracket 10 is disposed on the back side of the folding portion 213. The bracket 10 is disposed between the lens hole 2131 and the first rotating shaft 212 along a first direction, wherein the first direction intersects the extending direction of the first rotating shaft 212. The bracket 10 can extend and retract relative to the folding portion 213. In the retracted state, the bracket 10 is located entirely on the back side of the folding portion 213. In the extended state, one end of the bracket 10 extends toward one side of the folding portion 213 for placing the mobile terminal 30.

[0039] In other words, the bracket 10 is located on the back side of the folding part 213 and between the lens hole 2131 and the first pivot 212. This helps to position the bracket 10 in a relatively central position along the first direction of the folding part 213. With this arrangement, when the mobile terminal 30 is placed on the extended end of the bracket 10, the weight borne by the bracket 10 is mainly concentrated in the relatively central position of the folding part 213. In other words, the center of gravity of the protective shell assembly will not rise excessively, which helps to reduce the probability of the mobile terminal 30 tipping over when placed on the back panel 21 of the bracket 10, thereby helping to improve the stability of the mobile terminal 30 when placed on the bracket 10.

[0040] It is understood that the electronic device can be a tablet, laptop, mobile phone, etc. This application will use a tablet as an example for illustration.

[0041] It is understood that the mobile terminal 30 can be a mobile phone or a smartwatch. This application embodiment will use a mobile phone as the mobile terminal 30 for explanation.

[0042] The protective case assembly provided in this application embodiment has a bracket 10 that can extend from one side of the folding part 213 to hold a mobile phone. That is, the protective case assembly can support both the tablet and the mobile phone at the same time, making it easier for users to browse the content on the mobile terminal 30 while using the tablet, which helps to improve user work efficiency and user comfort.

[0043] Furthermore, the bracket 10 is located between the lens hole 2131 and the first pivot 212, which means that the bracket 10 can be located in a relatively central position on the back side of the folding part 213 along the first direction. This allows the weight borne by the bracket 10 to be mainly concentrated in the relatively central position of the folding part 213. In other words, the center of gravity of the protective case assembly will not be excessively raised, which helps to reduce the probability of the phone tipping over when placed on the back panel 21 of the bracket 10. This helps to improve the stability of the phone when placed on the bracket 10, and thus improves the stability of the entire protective case assembly.

[0044] For example, the first direction is Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in d1, the extension direction of the first rotating shaft 212 is... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The direction indicated by d2.

[0045] Please see Figure 6 The bracket includes a first bracket 11 and a second bracket 12, and the first bracket 11 and the second bracket 12 are rotatably connected. The first bracket 11 includes a plurality of first sub-parts 111 connected in sequence, and two adjacent first sub-parts 111 are rotatably connected. The bracket 10 includes a retracted state and an extended state.

[0046] In the stowed state, multiple first sub-parts 111 are laid flat along the extension direction of the first pivot 212, and the second support 12 extends along the extension direction of the first pivot 212. Each first sub-part 111 includes a first surface 111a and a second surface 111b facing away from each other. The second support 12 is stacked on the first surface 111a of the multiple first sub-parts 111, and the second surface 111b of the multiple first sub-parts 111 is used to connect to the folding portion 213. That is, in the stowed state, the first support 11 and the second support 12 are stacked along the thickness direction of the first sub-parts 111. This minimizes the overall size of the support 10 along the extension direction of the first pivot 212, facilitating the stowage of the support 10 to the back side of the folding portion 213.

[0047] In the extended state, the plurality of first sub-parts 111 include a first part and a second part. The second surface 111b of the second part is used to connect to the folding part 213. The first part is flipped to the first surface 111a of the second part and is laid flat with the second bracket 12 along the extension direction of the first pivot 212, so that the end of the second bracket 12 away from the first bracket 11 extends from one side of the periphery of the folding part 213 for placing the mobile terminal 30.

[0048] It should be noted that the plurality of first sub-parts 111 include a first part and a second part, meaning that the plurality of first sub-parts 111 of the first support 11 are divided into a first part and a second part, and the first part includes at least one first sub-part 111, the second part includes at least one first sub-part 111, and the sum of the number of first sub-parts 111 in the first part and the number of first sub-parts 111 in the second part is the total number of first sub-parts 111 of the first support 11.

[0049] It is understood that the first part refers to at least one first sub-part 111 that is laid flat along the extension direction of the second bracket 12 in the extended state, and the second part refers to at least one first sub-part 111 that is connected to the folding part 213 in the extended state. The number of first sub-parts 111 in the first part and the number of first sub-parts 111 in the second part are not fixed. The number of first sub-parts 111 in the first part and the number of first sub-parts 111 in the second part will change with the distance that the second bracket 12 extends along the extension direction of the first bracket 212.

[0050] In this embodiment, a portion of the first bracket 11, namely the first part, can be flipped to a position coplanar with the second bracket 12, thereby changing the position of the second bracket 12 in the folding portion 213, so that the end of the second bracket 12 away from the first bracket 11 can extend from one side of the periphery of the folding portion 213, thereby allowing the mobile terminal 30 to be placed at the end of the second bracket 12 away from the first bracket 11, that is, the mobile terminal 30 can be placed on one side of the folding portion 213 along the extension direction of the first rotation axis.

[0051] Furthermore, by adjusting the number of first sub-parts 111 in the first part, the distance by which the second bracket 12 extends beyond the folding portion 213 along the extension direction of the pivot 212 can be further adjusted. Firstly, by adjusting the extension distance of the second bracket 12, the distance between the phone and the folding portion 213 along the extension direction of the first pivot 212 can be adjusted. Secondly, the second bracket 12 can accommodate various phone placement configurations. That is, it can accommodate not only vertical placement of the phone (see [reference]). Figure 2 and Figure 3 It can also accommodate the horizontal placement of the phone (see [link]). Figure 4 and Figure 5Or it can be placed at a certain angle.

[0052] Please see Figure 2 and Figure 3 The vertical placement of the mobile phone refers to the position where the mobile phone is placed at the end of the second bracket 12 away from the first bracket 11, so that the contact area between the mobile phone and the second bracket 12 along the extension direction of the first rotating shaft 212 is minimized.

[0053] Please see Figure 4 and Figure 5 The horizontal placement of the mobile phone refers to the maximum contact size between the mobile phone and the second bracket 12 along the extension direction of the first pivot 212 when the mobile phone is placed at the end of the second bracket 12 away from the first bracket 11.

[0054] In some embodiments, a flexible connection portion 131 is formed at the junction of two adjacent first sub-parts 111 to enable a rotatable connection between the two adjacent first sub-parts 111; and / or, the bracket 10 includes a first hinge through which the two adjacent first sub-parts 111 are rotatably connected. The flexible connection portion 131 allows one of the adjacent first sub-parts 111 to be flipped to a position where it overlaps with the other first sub-part 111 along the thickness direction of the first sub-part 111, thereby facilitating the first part to overlap with the first surface 111a of the second part. The rotatable connection between the two adjacent first sub-parts 111 is achieved through the first hinge, allowing one of the adjacent first sub-parts 111 to be flipped to a position where it overlaps with the other first sub-part 111 along the thickness direction of the first sub-part 111. Furthermore, the first hinge also provides auxiliary support for the first sub-parts 111, helping to make the connection between the two overlapping first sub-parts 111 more stable.

[0055] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The bracket 10 includes a second hinge 14, and the second bracket 12 is a rigid member. The first bracket 11 and the second bracket 12 are rotatably connected by the second hinge 14. That is, the second hinge 14 is used to connect the second bracket 12 and the first sub-part 111 adjacent to the second bracket 12 in the first bracket 11. Moreover, the second hinge 14 can also provide auxiliary support for the second bracket 12 and the first bracket 11, which helps to make the second bracket 12 more stably positioned on the first bracket 11.

[0056] For example, such as Figure 6As shown, the second hinge 14 includes a first hinge piece 141, a second hinge piece 142, and a second pivot 143 connecting the first hinge piece 141 and the second hinge piece 142. The first hinge piece 141 is bonded to the first support 11, and the second hinge piece 142 is bonded to the second support 12. The bonding operation is convenient, and the bonding will not excessively increase the thickness between the first hinge piece 141 and the first support 11, or between the second hinge piece 142 and the second support 12.

[0057] For example, hot melt adhesive, pressure-sensitive adhesive, or instant adhesive can be used to achieve bonding.

[0058] In some embodiments, the first sub-part 111 includes a first magnetic attraction component 1111. In the retracted state, the first magnetic attraction component 1111 is used to magnetically engage with the folding part 213 and also to magnetically engage with the second bracket 12. In the extended state, the first magnetic attraction components 1111 of the two overlapping first sub-parts 111 are magnetically engaged, and the second bracket 12 is magnetically engaged with the first magnetic attraction component 1111 and / or the folding part 213 of the second sub-part 111.

[0059] In this embodiment, in the stored state, the first magnetic component 1111 attracts the second bracket 12, so that the second bracket 12 is detachably connected to the first bracket 11. The first magnetic component 1111 magnetically engages with the folding part 213, so that the first bracket 11 and the second bracket 12 are fixed together with the folding part 213, thereby realizing the storage of the bracket 10 on the back side of the folding part 213.

[0060] In the extended state, the first magnetic attraction components 1111 of the two overlapping first sub-parts 111 magnetically engage, and the second bracket 12 magnetically engages with the first magnetic attraction component 1111 and / or the folding portion 213 of the second part. The magnetic engagement of the first magnetic attraction components 1111 of the two overlapping first sub-parts 111 magnetically connects the overlapping areas of the first and second parts, thereby fixing the first part. The second bracket 12 can engage with either the first magnetic attraction component 1111 of the first sub-part 111 of the second part or with the folding portion 213, thereby fixing the second bracket 12.

[0061] It is understandable that the magnetic attraction between the second bracket 12 and the folding part 213 can be achieved by providing a magnetic attraction component on one of the second bracket 12 and the folding part 213, or by providing a magnetic attraction component on both the second bracket 12 and the folding part 213.

[0062] For example, in some embodiments, the protective shell 20 includes a magnetic element disposed on the folding portion 213. The magnetic element is magnetically attracted to the magnetic guide plate 15. Thus, the magnetic element can magnetically attract the second bracket 12 through the magnetic guide plate 15, so that the second bracket 12 can be stably connected to the folding portion 213 when it is extended.

[0063] In some other embodiments, the magnetic element protrudes from the back side of the folded portion 213 and is located on the side of the magnetic plate 15 near the end of the second support 12. Thus, when the first part and the second part are stacked, that is, when there is a gap between the second support 12 and the folded portion 213, the protruding magnetic element can provide relatively stable support and magnetic adsorption for the second support 12.

[0064] It is understandable that when the dimension of the first part along the extension direction of the first rotating shaft 212 is greater than the dimension of the second part along the extension direction of the first rotating shaft 212, the first magnetic attraction component 1111 of the first sub-part 111 in the second part cannot generate a magnetic attraction effect on the second bracket 12. At this time, the second bracket 12 needs to be magnetically engaged with the folding part 213 to fix the second bracket 12 in the folding part 213.

[0065] In some embodiments, the support 10 includes a flexible covering 13 that covers the outer periphery of a plurality of first sub-parts 111, and the flexible covering 13 forms a flexible connection 131 between two adjacent first sub-parts 111. The flexible covering 13 covers the outer periphery of the plurality of first sub-parts 111, thereby forming a single unit, i.e., the first support 11 becomes a single unit. The flexible covering 13 forms a flexible connection 131 between two adjacent first sub-parts 111, facilitating rotation between adjacent first sub-parts 111 and allowing one of the first sub-parts 111 to be flipped to a position where it overlaps with its adjacent first sub-part 111.

[0066] In some embodiments, the bracket 10 includes a magnetic plate 15 for connection with the folding portion 213, and a plurality of first magnetic attraction components 1111 of the first sub-parts 111 magnetically engage with the magnetic plate 15. The connection between the magnetic plate 15 and the folding portion 213, and the engagement of the plurality of first magnetic attraction components 1111 with the magnetic plate 15, helps to ensure a more stable magnetic engagement between the first magnetic attraction components 1111 and the magnetic plate 15, thereby making the bracket 10 more stably positioned on the back side of the folding portion 213.

[0067] For example, the magnetic plate 15 can be bonded to the folded portion 213. For example, bonding can be achieved by hot melt adhesive, pressure-sensitive adhesive, or instant adhesive.

[0068] It is understood that in some other embodiments, the bracket 10 includes a first bracket 11 and a second bracket 12. The first bracket 11 is connected to the folding portion 213, and the second bracket 12 is slidably disposed on the first bracket 11. In the extended state, one end of the second bracket 12 extends toward one side of the folding portion 213. That is, in this embodiment, the first bracket 11 can be fixed to the folding portion 213, and the extended and retracted states of the bracket can be changed by changing the sliding distance of the second bracket 12 on the first bracket 11.

[0069] There are several ways to achieve sliding. For example, the first support 11 can be set as a guide rail, and the second support 12 can include a slider. The sliding of the second support 12 on the first support 11 can be achieved through the cooperation of the guide rail and the slider.

[0070] Alternatively, the first support 11 can be configured as a sliding groove, and the second support 12 can include a slider. The sliding groove and the slider are used to enable the second support to slide on the first support 11.

[0071] In some embodiments, the bracket 10 includes a magnetic structure 16, which is located at the end of the bracket 10 extending toward the folding portion 213. The magnetic structure 16 is used to attract the mobile terminal 30. That is, the magnetic attraction of the mobile terminal 30 by the magnetic structure 16 allows the mobile terminal 30 to be placed on the bracket 10.

[0072] For example, the magnetic structure 16 is ring-shaped. The ring shape allows the magnetic structure 16 to provide magnetic force in multiple directions, which helps to stabilize the mobile terminal 30 when placed on the support 10.

[0073] In some embodiments, the annular magnetic structure 16 has a notch. The annular magnetic structure 16 with the notch can provide magnetic force to the mobile phone in multiple directions and also helps to reduce the cost of the magnetic structure 16.

[0074] In some embodiments, the magnetic attraction force provided by the magnetic attraction structure 16 is 9 to 11 Newtons (N), that is, 9N≤magnetic attraction force provided by the magnetic attraction structure 16≤11N. By controlling the magnetic attraction force of the magnetic attraction structure 16 within this range, it is possible to avoid the mobile terminal 30 being unstable when placed on the bracket 10 due to the magnetic attraction force being too small, and it is also possible to avoid the mobile terminal 30 being difficult to separate from the bracket 10 due to the magnetic attraction force being too large.

[0075] In some embodiments, the protective casing 20 also includes a keyboard 23, which is disposed on the support plate 22 and is used for signal connection with an electronic device or mobile terminal 30. By connecting the keyboard 23 to the electronic device or mobile terminal 30, typing input can be achieved using the keyboard 23. In this case, the user can type without operating the electronic device or mobile terminal 30, which helps to improve work efficiency.

[0076] In some embodiments, the protective shell 20 includes a damping pivot, and the support plate 22 and the connecting part 211 are rotatably connected through the damping pivot. Thus, by rotating the connecting part 211 around the damping pivot, the angle between the back plate 21 as a whole and the support plate 22 can be changed. That is, the display angle of the tablet can be adjusted by adjusting the angle between the connecting part 211 and the support plate 22.

[0077] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application.
