[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, this utility model provides a specific embodiment of a protective device.

[0025] A protective device, reference Figure 1 and Figure 2 The protective device includes at least two protective shells 100 and a connecting middle shell 200 disposed between two adjacent protective shells 100. The connecting middle shell 200 includes a base plate 210 and two clamping arms 220. The base plate 210 and the two clamping arms 220 enclose a clamping space for clamping the two protective shells 100. At least one of the two clamping arms 220 is movably connected to the base plate 210 to adjust the distance between the two clamping arms 220. The two protective shells 100 are respectively provided with sidewalls 110 that cooperate with and connect with the two clamping arms 220. One of the protective shells 100 is provided with a belt 300 that can slide relative to the protective shell 100.

[0026] Specifically, refer to Figure 1 and Figure 2The protective device includes two protective shells 100 and a connecting middle shell 200. The two protective shells 100 are used to cover the folding screen device to protect the back of the two screens of the folding screen device respectively. The connecting middle shell 200 is disposed between the two protective shells 100 to connect the two protective shells 100 and protect the folding part of the folding screen device. The clamping arms 220 at both ends of the connecting middle shell 200 can clamp the two ends of the two protective shells 100 respectively. The clamping space formed by the clamping arms 220 at both ends of the connecting middle shell 200 can accommodate the two protective shells 100, and the two protective shells 100 can rotate relative to the connecting middle shell 200 to achieve folding or unfolding.

[0027] Furthermore, at least one of the two clamping arms 220 is movably connected to the base plate 210 and can extend and retract relative to the base plate 210 to adjust the distance between the two clamping arms 220, thereby facilitating the installation of the protective shell 100 in the clamping space or its removal from the clamping space. The two protective shells 100 are respectively provided with side walls 110 on both sides for cooperating with the clamping arms 220, thereby realizing the rotational connection between the protective shell 100 and the connecting middle shell 200.

[0028] Furthermore, one of the protective cases 100 is provided with a strap 300 that can slide relative to the protective case 100. The strap 300 can be put on the finger to reduce the probability of the device accidentally slipping off. The strap 300 can also be hung on other items to fix the phone to prevent it from being lost.

[0029] Currently, a large number of foldable screen devices have appeared on the market, which have unique unfolding and folding modes to provide a more flexible way of use. The emergence of a large number of foldable screen devices has increased the demand for protective cases suitable for foldable screen devices. Existing foldable protective cases usually require that multiple parts of the protective case be matched with different positions of the foldable screen device and then fixed one by one. This is not only complex in structure and very inconvenient to disassemble and assemble, but also has limited functions and cannot meet the diverse needs of users.

[0030] In this embodiment, a protective device is designed, including at least two protective shells 100 and a connecting middle shell 200 disposed between two adjacent protective shells 100. The connecting middle shell 200 includes a base plate 210 and two clamping arms 220. The base plate 210 and the two clamping arms 220 enclose a clamping space for clamping the two protective shells 100. At least one of the two clamping arms 220 is movably connected to the base plate 210 to adjust the distance between the two clamping arms 220. Side walls 110 that cooperate with and connect to the two clamping arms 220 are respectively provided on both sides of the two protective shells 100. A belt 300 that can slide relative to the protective shell 100 is provided on one of the protective shells 100. By setting at least one clamping arm 220 to be movably connected to the base plate 210, the clamping space can be adjusted to facilitate the assembly and disassembly of the two protective shells 100. By providing a belt 300 on one of the protective shells 100, the probability of the device accidentally slipping is effectively reduced, resulting in richer functions and higher practicality.

[0031] In one embodiment, reference Figure 2 The clamping arm 220 and the side wall 110 have a rotating shaft 221 protruding on one surface and a first groove 111 that engages with the rotating shaft 221 on the other surface.

[0032] Specifically, refer to Figure 2 The inner surfaces of the two clamping arms 220 are symmetrically provided with rotating shafts 221 at both ends. The side walls 110 of the two protective shells 100 are respectively provided with first grooves 111 for connecting with the two rotating shafts 221. Alternatively, the two rotating shafts 221 can be provided on the side walls 110 of the two protective shells 100, and the two first grooves 111 can be provided on both sides of the side walls 110.

[0033] In one embodiment, the first groove 111 is an elongated inclined groove. During the rotation of the protective shell 100 relative to the connecting middle shell 200, the rotating shaft 221 can move along the length direction of the first groove 111.

[0034] In one embodiment, the movable clamping arm 220 is connected to the end of the base plate 210 via an elastic connecting component. It can be configured such that both clamping arms 220 are telescopically connected to the two ends of the base plate 210 via the elastic connecting component, so as to move closer to or further away from each other to adjust the distance between them. Alternatively, only one clamping arm 220 can be configured to be movable, and this clamping arm 220 is connected to one end of the base plate 210 via the elastic connecting component, so as to move closer to or further away from another clamping arm 220 connected to the other end of the base plate 210, thereby adjusting the distance between them.

[0035] It should be noted that, in addition to the elastic connection component, the spacing between the two clamping arms 220 can also be adjusted by using a threaded telescopic rod structure, a damped telescopic result, or a rack and pinion transmission telescopic structure.

[0036] In one embodiment, reference Figure 3 The elastic connection assembly includes at least one connecting rod 410 parallel to the base plate 210, and a telescopic spring 420 sleeved on the connecting rod 410; one end of the connecting rod 410 is fixedly connected to the base plate 210, and the other end is movably connected to the clamping arm 220; the free end of the connecting rod 410 is provided with a limiting structure 430 to prevent the clamping arm 220 from disengaging from the connecting rod 410, and the telescopic spring 420 provides elastic force to the limiting structure 430 and the clamping arm 220.

[0037] The telescopic spring 420 can be disposed between the first limiting part and the clamping arm 220. When the two clamping arms 220 are stretched outward simultaneously or one of them, the telescopic spring 420 is deformed and compressed or stretched by the force applied by the clamping arm 220. Both clamping arms 220 move in the length direction away from the base plate 210, so that the distance between the two clamping arms 220 increases. When the clamping arm 220 loses the external force, the telescopic spring 420 automatically resets and drives the clamping arm 220 to move closer to the base plate 210, so that the distance between the two clamping arms 220 decreases.

[0038] In one embodiment, at least one fastener is provided on one of the protective shells, and at least one end of the strap is fixed to the fastener.

[0039] Specifically, refer to Figure 2 and Figure 4 One of the protective shells 100 is provided with a first fixing member 120 and a second fixing member 130. One end of the belt body 300 is provided with a through hole 310, and the other end of the belt body 300 is provided with a U-shaped hole 320. The first fixing member 120 passes through the through hole 310 and is fixed to one end of the belt body 300. The second fixing member 130 passes through the U-shaped hole 320 and is movably connected to the other end of the belt body 300. When the belt body 300 is in contact with the protective shell 100, the second fixing member 130 is limited to one end of the U-shaped hole 320. When the belt body 300 slides and arches relative to the protective shell 100, the second fixing member 130 is limited to the other end of the U-shaped hole 320.

[0040] It should be noted that a fixing component and a magnetic component can also be installed on one of the protective shells. One end of the strap is fixed to the fixing component, and the other end of the strap can be arched or fitted relative to the protective shell, and magnetically fixed to the magnetic component on the protective shell in the arched or fitted state. Alternatively, an elastic strap can be used, and both ends of the strap can be fixed to two fixing components on the protective shell respectively, using the elasticity of the strap to achieve both fitted and arched states.

[0041] In the unused state, the strap 300 fits against the protective shell 100, and the second fastener 130 is limited to one end of the U-shaped hole 320. During use, a finger is passed through the strap 300, causing the strap 300 to slide and arch relative to the protective shell 100 to provide space for the finger. During the sliding of the strap 300 relative to the protective shell 100, its U-shaped hole 320 moves relative to the second fastener 130, causing the second fastener 130 to abut against the other end of the U-shaped hole 320 for limiting.

[0042] In one embodiment, reference Figure 4 The outer side of the base plate 210 is recessed with a receiving groove 211, and a support frame 212 is provided in the receiving groove 211. The support frame 212 can rotate relative to the base plate 210 and be stored in the receiving groove 211. The support frame 212 is used to improve the ease of use of the equipment. The support frame 212 can be unfolded to stand the equipment on the table, freeing up the hands and eliminating the need to carry an additional table stand. This effectively improves the functionality of the entire protective device and makes it more practical.

[0043] The recessed receiving groove 211 on the outer side of the base plate 210 allows the support frame 212 to be stored when not in use, thus reducing the space occupied by the protective device. By setting both the receiving groove 211 and the support frame 212 on the outer side of the base plate 210, when the two protective shells 100 of the protective device are unfolded, the support frame 212 can be supported precisely in the middle of the folding screen device, effectively improving the stability of the support.

[0044] In one embodiment, reference Figure 4 The support frame 212 is rotatably connected to the base plate 210 via a connecting structure. The connecting structure includes a first connecting plate 2131 and a second connecting plate 2132 that are rotatably connected. The first connecting plate 2131 is fixed to the base plate 210, and the second connecting plate 2132 is fixed to one end of the support frame 212.

[0045] In one embodiment, reference Figure 4 The support frame 212 also includes an extension 214, which is connected to the other end of the support frame 212. When the support frame 212 is stored in the receiving groove 211, the extension 214 fits against the outer side of the base plate 210. The extension 214 is detachably connected to the other end of the support frame 212 to adapt to different usage scenarios and different user needs.

[0046] In one embodiment, reference Figure 2The bottom plate 210 has eaves 2111 on both sides of the surface facing the clamping space to limit the two protective shells 100; when the two protective shells 100 are extended outward to be parallel to the bottom plate 210, the multiple eaves 2111 respectively position the two protective shells 100 so that the two protective shells 100 remain parallel.

[0047] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
