Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The preferred embodiment of the present invention is an electronic device protective shell for foldable electronic devices. The electronic device protective shell in the present invention is a shell specially designed for various electronic devices, used to protect the devices from collisions, scratches, falls and dust, etc. It can effectively protect the appearance and internal components of the device and extend the service life of the electronic device. Electronic devices include but are not limited to mobile phones, tablet computers, laptop computers, readers, etc. Among them, the embodiment of the present invention is analyzed and explained by taking a mobile phone protective shell as an example. Figure 1-2 As shown, there are respectively shown the folded state diagram and the unfolded state diagram of the electronic device protective shell, which includes at least two protective shells 10; a connecting middle shell 20 is provided between the two adjacent protective shells 10; wherein, the connecting middle shell 20 includes a bottom plate 21 and two clamping arms 22; in one embodiment, both clamping arms 22 are movably connected to the bottom plate 21; optionally, only one clamping arm 22 can be movably connected to the bottom plate 21; the bottom plate 21 and the two clamping arms 22 enclose a clamping space 23 for clamping the two protective shells 10; the distance between the two clamping arms 22 is adjustable, so that the protective shell can be easily installed in the clamping space or removed from the clamping space. Side walls 11 that are connected to the two clamping arms 22 are provided on both sides of the two protective shells 10; as shown Figure 3As shown, in one embodiment, rotating shafts 24 are symmetrically protruded on both sides of the inner surfaces of the two side walls 11, and the side walls of the two protective shells 10 are respectively provided with first grooves 12 that cooperate with the two rotating shafts 24; optionally, the two rotating shafts 24 can also be respectively provided on the side walls of the two protective shells 10, and the two first grooves 12 are provided on both sides of the side wall 11; the above simple position replacements all fall within the scope of protection of the present utility model.

[0027] The electronic device protective shell has a simple structure. The bottom plate and the two clamping arms enclose a clamping space for clamping the two protective shells. The size of the clamping space can be adjusted by adjusting the distance between the two clamping arms so that the two protective shells can be directly inserted into the connected middle shell or directly removed from the connected middle shell. When the two protective shells are installed in place, the rotating shaft is engaged with the corresponding first groove to achieve movable positioning, and the installation is stable. During the process of folding and rotating the two protective shells relative to the connected middle shell, the rotating shaft rotates in the first groove and rotates flexibly. When disassembling, the protective shell can be removed from the connected middle shell by simply adjusting the distance between the two clamping arms again to separate the rotating shaft from the first groove, and the disassembly and assembly are simple.

[0028] In this embodiment, the electronic device protective shell has a folded state and an unfolded state; Figure 1 As shown, the electronic device protective shell is folded. At this time, the two protective shells are parallel to each other and are located at the upper and lower ends of the inner side of the connecting middle shell. The two protective shells are arranged perpendicular to the connecting middle shell. The folded electronic device protective shell is small in size and easy to store. Figure 2 As shown, it shows the state diagram of the electronic device protective shell being unfolded. At this time, the two protective shells are parallel to the connecting middle shell, and both protective shells overlap with the connecting middle shell at least in part. The unfolded electronic device protective shell is similar in shape to the unfolded mode of the mobile phone; it is flexible to use.

[0029] Furthermore, the first groove 12 is a long inclined groove; during the rotation of the protective shell 10 relative to the connected shell 20, the shaft 24 can move along the length direction of the first groove 12, so that the protective shell 10 has a larger range of rotation and more flexible rotation.

[0030] In this embodiment, the movable clamping arms 22 are connected to the left and right ends of the base plate 21 through an elastic connection component 25; the two clamping arms 22 can move closer to or farther away from each other to adjust the distance between them; optionally, the two clamping arms 22 can also adopt a threaded telescopic rod structure or a damping telescopic structure or a rack and gear transmission telescopic distance adjustment structure in the prior art to achieve distance adjustment.

[0031] like Figure 4As shown, the elastic connecting assembly 25 includes at least one connecting rod 251 parallel to the base plate 21; a telescopic spring 252 is sleeved on the connecting rod 251; one end of the connecting rod 251 is fixedly connected to the base plate 21, and the other end is movably connected to the clamping arm 22; the free end of the connecting rod 251 is provided with a first limiting portion 253 to prevent the clamping arm 22 from detaching from the connecting rod 251; the telescopic spring 252 provides elastic force to the first limiting portion 253 and the clamping arm 22; the telescopic spring 252 can be arranged between the first limiting portion 253 and the clamping arm 22. When the two clamping arms 22 are stretched outward at the same time, the telescopic springs 252 on both sides are deformed, compressed or stretched by the force applied by the clamping plate, and the two clamping arms 22 move in the length direction away from the base plate 21, so that the distance between the two clamping arms 22 increases; when the clamping arms 22 lose the external force, the telescopic spring 252 automatically resets and drives the clamping arms 22 closer to the base plate 21, so that the distance between the two clamping arms 22 decreases.

[0032] Furthermore, the clamping arm 22 is provided with a movable slot 221 through which the connecting rod 251 passes and into which the telescopic spring 252 rests. The telescopic spring 252 is concealed within the movable slot 221, enhancing the aesthetics of the connected housing while also protecting it from environmental influences. A retaining surface 222 is provided on the side of the movable slot 221 facing the base plate 21, preventing the first retaining portion 253 from disengaging from the clamping arm 22 and supporting the telescopic spring 252. The ends of the telescopic spring 252 abut against the first retaining portion 253 and the retaining surface 222, respectively, ensuring a stable connection.

[0033] Alternatively, if Figure 3 As shown, a second groove 211 is provided inwardly along the length direction of the bottom plate 21 on one side surface facing the clamping space 23; a certain amount of space is provided for the two protective shells and the folding mobile phone to avoid movement, which not only facilitates the two protective shells to be flexibly folded and rotated on the connecting middle shell, but also when the folding mobile phone and the electronic protective shell are folded and rotated, the central axis of the folding mobile phone will not hit the connecting middle shell, which can effectively avoid scratching the central axis of the folding mobile phone.

[0034] Furthermore, a window 212 is provided on the bottom plate 21 and is connected to the second groove 211. When the two protective shells are folded, the window 212 allows the user to clearly see the logo on the mobile phone.

[0035] Furthermore, the two side edges of the bottom plate 21 facing the clamping space 23 are respectively provided with eaves 213; when the two protective shells are expanded outward to be parallel to the bottom plate, the multiple eaves respectively position the two protective shells 10 so that the two protective shells 10 remain parallel.

[0036] Furthermore, at least one side wall 11 of the protective shell 10 is provided with a second limiting portion 13 parallel to the upper surface of the electronic device; the plurality of second limiting portions can make the electronic product fit more closely with the protective shell.

[0037] Furthermore, a bracket 14 for supporting electronic products is provided on the back of any protective shell 10. The addition of the bracket makes the mobile phone protective shell no longer just a tool for protecting the mobile phone, but can also be used as a support device when watching videos, thereby increasing the practicality of the product.

[0038] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
