[0029] Embodiment 1:

[0030] A protective case for an electronic device according to a preferred embodiment of the present utility model. The protective case for an electronic device in the present utility model is a casing designed specifically for various electronic devices, used to protect the device from collisions, scratches, falls, dust, etc., and can effectively protect the appearance and internal components of the device, extending the service life of the electronic device. The electronic device includes, but is not limited to, mobile phones, tablet computers, laptop computers, readers, etc. Among them, the embodiment of the present utility model will be analyzed and described by taking a mobile phone case as an example. As Figure 1 shown, a protective case for an electronic device includes a back panel 10. Among them, the back panel 10 includes a substrate 11 and two movable plates 12 movably provided at the lower end of the substrate 11; in this embodiment, the back panel 10 is disposed on the back of the electronic device, and the two movable plates 12 are arranged side by side at the lower end of the substrate 11. In this embodiment, first edge wrappings 111 are provided on both the left and right sides of the substrate 11; second edge wrappings 121 are provided on both movable plates 12; the two first edge wrappings 111 respectively correspond to and protect the two top corners at the upper end of the electronic device; the two second edge wrappings 121 respectively protect the two top corners at the lower end of the electronic device.

[0031] In this embodiment, as Figure 2 shown, the two movable plates 12 can move relatively to the substrate 11 towards the two outer sides respectively; the outer sides of the substrate 11 are the outer sides of the left and right sides of the substrate; the two movable plates 12 move away from each other towards the left and right outer sides of the substrate respectively, and the distance between the two second edge wrappings increases accordingly. During the movement of the two movable plates 12, they both have a first state and a second state; as Figure 1 shown, when the two movable plates 12 are both in the first state, the two first edge wrappings 111 and the two second edge wrappings 121 enclose a first protection cavity for providing protection to the electronic device; at this time, the two first edge wrappings 111 and the two second edge wrappings 112 wrap the electronic device in the first protection cavity and fix it; as Figure 2 shown, when the two movable plates 12 are both in the second state, the two first edge wrappings 111 and the two second edge wrappings 121 enclose a second protection cavity, and the electronic device can be taken out from the second protection cavity; at this time, the distance between the two second edge wrappings is greater than the width of one end of the electronic device, thereby facilitating the removal of the electronic device from the second protection cavity; the design of this protective case for an electronic device is ingenious, and the purpose of quickly disassembling and assembling the protective case for an electronic device on the mobile phone can be achieved by switching the states of the two movable plates, which is convenient to use.

[0032] In this embodiment, the two movable plates 12 can be movably connected to the substrate 11. Optionally, in another embodiment, the electronic device protective case may further include a bottom plate (not shown in the figure); the two movable plates 12 and the substrate 11 can both be connected to the bottom plate; wherein, the substrate 11 and the movable plates 12 are both disposed on the same side of the bottom plate (not shown in the figure); the substrate 11 can be a part of the bottom plate (not shown in the figure), or can be fixedly connected to the bottom plate (not shown in the figure); the two movable plates 12 are both movably connected to the bottom plate (not shown in the figure), and the two movable plates are both disposed at the lower end of the substrate 11.

[0033] In this embodiment, as Figure 1 shown, when the two movable plates 12 are both in the first state, the two movable plates 12 are connected and fixed by the connecting component 13, and the connection is stable.

[0034] In this embodiment, the two movable plates 12 are both rotatably connected to the substrate 11; the rotation plane of the movable plate 12 and the plane where the substrate 11 is located are both in the same plane; the rotation plane and the plane of the substrate are coplanar, which can improve the structural stability, reduce the stress concentration and structural distortion caused by non-coplanar planes, and the coplanar design can reduce the space required for the movement of the movable plate.

[0035] In this embodiment, as Figure 3 shown, on the side surface of the substrate 11 facing the movable plate 12, there is a connecting portion 112 protruding outward, and on the outer side surface of the movable plate 12, there is a movable groove 122 for the connecting portion 112 to be inserted; optionally, the connecting portion 112 can also be disposed on the movable plate 12, and the movable groove 122 is disposed on the substrate 11; there is a rotating shaft (not shown in the figure) in the movable groove 122; the connecting portion 112 rotates in the movable groove 122 through the rotating shaft (not shown in the figure); optionally, both the connecting portion 112 and the movable groove 122 are strip-shaped, and the size of the connecting portion 112 is smaller than the size of the movable groove 122; the connecting portion 112 is eccentrically rotatably connected to the rotating shaft (not shown in the figure). On both connecting portions 112, there is a first stop surface 1121; on the substrate 11, there is a second stop surface 113; optionally, the second stop surface 113 can also be disposed on one side surface of the connecting portion 112. When the two movable plates 12 are both in the first state, the bottom surface of the movable groove 122 abuts against the first stop surface 1121, the two movable plates 12 are closed, the area of the first protection cavity is adapted to the outer contour of the electronic device, and the electronic device can be fixed in the first protection cavity through four side wraps. When the two movable plates 12 are both in the second state, the movable plate 12 abuts against the second stop surface 113, the two movable plates 12 are respectively opened outward, and the area of the second protection cavity is larger than the area of the first protection cavity, which is convenient for taking out the electronic device from the second protection cavity.

[0036] Further, as Figures 3 - 5As shown in the figure, the connecting component 13 includes a hook 131 disposed on the surface of a movable plate 12, and a locking groove 132 disposed on another movable plate 12; a locking block 133 is slidably disposed in the locking groove 132, and an elastic member 134 that provides an elastic force to the locking block 133; the elastic member 134 is a spring in the prior art; the movable plate 12 having the locking groove 132 is provided with a locking hole 135 communicating with the locking groove 132 and for the hook 131 to be inserted, and a pushing member 136 slidably connected to the movable plate 12 and fixedly connected to the locking block 133; the locking block 133 is provided with a clamping groove 1331 that cooperates with the hook 131 for clamping; when the hook 131 is inserted into the locking hole 135, the elastic member 134 drives the locking block 133 to be clamped with the hook 131. When unlocking, only apply a force to the pushing member 136 to compress the elastic member 134 and move the locking block away from the locking hole, so that the locking block is separated from the hook, and then the hook can be pulled out of the locking hole to release the connection state of the two movable plates. Then move the two movable plates away from each other to the second state to take out the electronic device from the second protection cavity. During installation, both movable plates are in the second state. The user only needs to put the electronic device into the second protection cavity, and then move the two movable plates relative to each other to the first state at the same time, so that the second protection cavity is switched to the first protection cavity. During the process of the hook being inserted into the locking groove 132 from the locking hole 135, the hook applies a squeezing force to the locking block 133 and compresses the elastic member 134. When the hook is clamped with the clamping groove on the locking block 133, the locking block 133 loses the squeezing force, and the elastic member automatically resets and drives the locking block to clamp the hook tightly in the locking groove. At this time, the four side wraps limit and fix the mobile phone in the first protection cavity, achieving the purpose of quickly disassembling and assembling the electronic device protective case on the mobile phone.

[0037] Optionally, in order to ensure that the hook can be accurately inserted into the locking hole; positioning protrusions 124 are respectively provided on the opposite outer side surfaces of the two movable plates 12, and positioning grooves 125 adapted to the positioning protrusions 124; when the two movable plates 12 are closed, the positioning protrusions 124 are inserted and positioned with the positioning grooves 125. In this embodiment, the positioning protrusion 124 is gradually expanding from the outside to the inside, and both top corners of the positioning protrusion 124 are provided with rounded corners, so that the positioning protrusion can easily enter the positioning groove or easily disengage from the positioning groove.

[0038] In another embodiment, the two movable plates 12 can also be dampedly connected to the substrate by using a damping structure in the prior art, such as a damping connecting piece, a damping hinge, a damper, etc., so as to achieve the purpose of damping connection between the movable plate and the substrate, and further achieve the purpose of the two movable plates moving and being controlled and positioned on the substrate; the connecting component described above may not be used between the two movable plates. After the user applies a force to the two movable plates 12 to make both movable plates in the first state and then withdraws the external force, under the influence of no external force, the damping force between the two movable plates and the substrate can keep both movable plates in the first state and will not easily undergo relative displacement.

[0039] Further, in order to provide additional protection and security when the user accidentally drops or collides the mobile phone, thereby reducing the risk of damage to the mobile phone, protective airbags 14 are provided on both the first edge 111 and the second edge 121 of the electronic device protective case. When the mobile phone drops, the protective airbags 14 can play a buffering role, absorb the impact force, and reduce the direct impact on the mobile phone.

[0040] Further, a bracket 15 for supporting the electronic device is provided on the substrate 11. The addition of the bracket makes the mobile phone protective case no longer just a tool for protecting the mobile phone, but also can be used as a supporting device when watching videos, increasing the practicality of the product.

[0041] Embodiment 2

[0042] This embodiment provides an electronic device protective case. The same parts as those in Embodiment 1 will not be described in detail. The differences are as Figure 6 and Figure 7 shown. Both movable plates 12 are slidably connected to the substrate 11. On the two outer side surfaces of the substrate 11 and the movable plates 12 that are opposite to each other, one of the outer side surfaces is provided with an outwardly protruding slider 114, and the other outer side surface is provided with a chute 123 that is slidably connected to the slider 114. The chute 123 is provided with a first position a and a second position b that are communicated with each other. As Figure 6 shown, when both movable plates 12 are in the first state, both sliders 114 move to the first position a and the two movable plates 12 are closed together. The area of the first protection cavity is adapted to the outer contour of the electronic device, and the electronic device can be fixed in the first protection cavity through the four edges. As Figure 7 shown, when both movable plates 12 are in the second state, both sliders 114 move to the second position b and the two movable plates 12 are opened outwards respectively. The area of the second protection cavity is larger than that of the first protection cavity, which is convenient for taking out the electronic device from the second protection cavity.

[0043] Optionally, the connecting component can also be a first magnet 137 and a second magnet 138 that cooperates with the first magnet 137 for magnetic attraction. The first magnet 137 is arranged on one side surface of a movable plate 12, and the second magnet 138 is arranged on the opposite side surface of the other movable plate 12. When both movable plates are in the first state, the first magnet and the second magnet attract each other.
