[0035] This section will combine Figures 1 to 11 Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0036] In the description of the present application, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like are used to indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The features defined as "first" and "second" are used to distinguish the feature names, rather than having special meanings. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0037] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] like Figure 1 As shown, an embodiment of the present application provides an electronic device protective case, which includes an inner shell 101 and an outer shell 201. The inner shell 101 is sleeved on the back of the electronic device, and the outer shell 201 is installed on the outside of the inner shell 101. The inner shell 101 and the outer shell 201 are detachably connected, so that the inner shell 101 and the outer shell 201 together provide protection for the electronic device.

[0039] like Figure 2 As shown, in some examples, the inner shell 101 includes an inner shell back plate and an inner shell periphery, the inner shell periphery is at the edge of the inner shell back plate and extends at an angle from the edge of the inner shell back plate, and the inner shell back plate and the inner shell periphery enclose a space for the electronic device to be embedded. It can be understood that the size of the inner shell back plate and the inner shell periphery is set according to the shape of the electronic device, and when the inner shell 101 is sleeved on the back of the electronic device, the inner shell back plate covers the back of the electronic device, and the inner shell periphery covers the edge of the electronic device.

[0040] The inner shell 101 is made of a soft wear-resistant material. Specifically, the inner shell 101 is made of TPU plastic material, which has strong wear resistance and corrosion resistance, thereby preventing the inner shell 101 from being worn, scratched, and discolored by sweat corrosion.

[0041] like Figure 3 As shown, in some examples, the outer shell 201 includes an outer shell back and an outer shell periphery, and the outer shell periphery is at the edge of the outer shell back plate and extends at an angle from the edge of the outer shell back. The size of the outer shell back and the outer shell periphery is set according to the shape of the inner shell 101, so that the outer shell 201 can be connected to the outer side of the inner shell 101, and the inner shell 101 and the outer shell 201 are stacked and sleeved on the back of the electronic device to provide protection for the electronic device. It can be understood that when the outer shell 201 is connected to the outer side of the inner shell 101, the outer shell periphery surrounds the outer side of the inner shell periphery.

[0042] The outer shell 201 is made of a hard material, specifically, the outer shell 201 is made of hard plastic material and has a certain structural strength. When the outer shell 201 is used in combination with the inner shell 101, the outer shell 201 increases the overall strength of the protective shell of the electronic device.

[0043] At the same time, the back of the outer shell includes a first hollow portion 202, and the inner shell back plate includes a protrusion 102, the shape of the protrusion 102 matches the shape of the first hollow portion 202, and when the outer shell 201 is installed on the outer side of the inner shell 101, the protrusion 102 passes through the first hollow portion 202 and protrudes out of the back of the outer shell. Since the protrusion 102 is made of TPU plastic material, the wear resistance and corrosion resistance of the back of the electronic device protective shell are improved.

[0044] In addition, the inner shell 101 is connected to the outer shell 201 in a plug-in manner, so that the inner shell 101 and the outer shell 201 form a whole. Specifically, the side edge of the inner shell back plate is provided with a first slot 103, and the outer shell peripheral edge includes a first plug-in portion 203, the shape of the first plug-in portion 203 matches the shape of the first slot 103, and when the outer shell 201 is installed on the outer side of the inner shell 101, the first plug-in portion 203 is inserted into the first slot 103.

[0045] Furthermore, the inner shell 101 and the outer shell 201 include a lock screen side and an adjustment side, which respectively correspond to the side of the electronic device where the lock screen key is set and the side of the electronic device where the adjustment button is set. The lock screen side and the adjustment side of the inner shell 101 are both provided with a first slot 103, and correspondingly, the outer shell edges on the lock screen side and the adjustment side are both provided with a first plug-in portion 203.

[0046] like Figure 4 and Figure 5 As shown, in some examples, the inner shell periphery includes an anti-skid portion 104 protruding outward, the first slot 103 is between the anti-skid portion 104 and the inner shell back plate, and the first plug-in portion 203 is recessed inwardly into the outer shell periphery. When the first plug-in portion 203 is inserted into the first slot 103, the first plug-in portion 203 and the anti-skid portion 104 are stacked, and at this time, among the first plug-in portion 203 and the anti-skid portion 104, the first plug-in portion 203 is close to the edge of the electronic device, while the anti-skid portion 104 is far away from the edge of the electronic device, and the anti-skid portion 104 is exposed to the outside of the protective shell of the electronic device.

[0047] The outer surface of the anti-skid portion 104 is provided with anti-skid stripes, and when the user holds the electronic device, the anti-skid stripes can increase the friction between the electronic device protective shell and the user's hand, thereby improving the holding stability. It can be understood that the anti-skid portion 104 exists on both the lock screen side and the adjustment side of the inner shell 101.

[0048] like Figure 8 , Fig. 9 and Fig.11As shown, in some examples, in order to ensure the stable connection between the inner shell 101 and the outer shell 201, the end of the first plug-in portion 203 is provided with a first clamping structure 204, and the first clamping structure 204 extends in the direction of the anti-slip portion 104 to form a certain protrusion. At the same time, the inner side of the anti-slip portion 104 is provided with a first clamping groove 105, and the first clamping groove 105 forms a step shape on the inner side of the anti-slip portion 104. In the process of inserting the first plug-in portion 203 into the first slot 103, the first clamping structure 204 constantly approaches the first clamping groove 105. When the first plug-in portion 203 is plugged in place, the first clamping structure 204 is embedded in the first clamping groove 105, thereby locking the connection between the inner shell 101 and the outer shell 201, and preventing the outer shell 201 from accidentally falling off from the inner shell 101.

[0049] like Figure 6 and Figure 7 As shown, in some examples, the angled position of the electronic device is prone to collision damage, so an anti-collision structure is correspondingly provided at the angled position of the protective shell of the electronic device.

[0050] The inner shell periphery includes an anti-collision portion 106 protruding outward, the anti-collision portion 106 is at an angled position of the inner shell 101, and a second slot 107 is provided between the anti-collision portion 106 and the inner shell back plate. At the same time, the outer shell periphery includes a second plug-in portion 205, and the second plug-in portion 205 is recessed in the outer shell periphery, and the shape of the second slot 107 matches the shape of the second plug-in portion 205. When the outer shell 201 is installed on the inner shell 101, similar to the plug-in method of the first plug-in portion 203 and the first slot 103, the second plug-in portion 205 is also inserted into the second slot 107, then the second plug-in portion 205 and the anti-collision portion 106 are stacked, and the anti-collision portion 106 is exposed outside the electronic device protective shell, so as to improve the anti-collision performance of the electronic device protective shell and fully protect the electronic device.

[0051] Furthermore, to ensure that the second plug-in portion 205 is smoothly inserted into the second slot 107, there is a storage space at the angled position of the inner housing 101 that is connected to the second slot 107, so as to accommodate the second slot 107. At the same time, the volume of the storage space is larger than the volume of the second plug-in portion 205. When the second plug-in portion 205 is inserted into the second slot 107, the storage space is not yet filled, and the unfilled part of the storage space forms an air groove, providing space for the anti-collision portion 106 to deform. When the anti-collision portion 106 is impacted, the anti-collision portion 106 will form a certain elastic deformation to buffer the impact, further enhancing the protective effect of the electronic device protective shell.

[0052] like Figure 8 , Fig.10 and Fig.11As shown, in some examples, similar to the first plug-in portion 203 and the first slot 103, the end of the second plug-in portion 205 is provided with a second snap-fit ​​structure 206, and the second snap-fit ​​structure 206 extends in the direction of the anti-collision portion 106 to form a certain protrusion. At the same time, a second snap-fit ​​groove 108 is provided on the inner side of the anti-collision portion 106. When the second plug-in portion 205 is plugged in place, the second snap-fit ​​structure 206 is embedded in the second snap-fit ​​groove 108, thereby locking the connection between the inner shell 101 and the outer shell 201, and preventing the outer shell 201 from accidentally falling off from the inner shell 101.

[0053] In some examples, there are buttons such as a lock screen button and a volume adjustment button on the side edge of the electronic device. To ensure the sensitivity of the buttons of the electronic device, the inner shell edge includes a plurality of protruding button portions 301. Correspondingly, the outer shell edge includes a plurality of avoidance notches 304. The shape of the avoidance notches 304 matches the shape of the button portions 301. When the outer shell 201 is installed on the inner shell 101, the button portions 301 are embedded in the avoidance notches 304 and are exposed on the outside of the protective shell of the electronic device, ensuring that the user can operate the buttons of the electronic device through the button portions 301.

[0054] It can be understood that the button portion 301 is provided with an active button 302 , and the position of the active button 302 corresponds to the button of the electronic device and conflicts with the button of the electronic device.

[0055] In some examples, the button portion 301 is provided with an active groove 303, which is opened at the edge of the active key 302 to reduce the connection strength between the active key 302 and the main body of the button portion 301, reduce the resistance encountered by the user when pressing the active key 302, and improve the button sensitivity of the electronic device by improving the deformation ability of the active key 302.

[0056] In some examples, a camera is often provided on the back of the electronic device. It is understandable that the camera needs to be exposed to the electronic device protective shell to ensure the normal operation of the camera. Therefore, the inner shell back plate includes a second hollow portion 401, and the outer shell back includes a third hollow portion 402. The second hollow portion 401 is connected to the third hollow portion 402, and the shape of the second hollow portion 401 and the shape of the third hollow portion 402 both match the shape of the camera portion of the electronic device. When the electronic device protective shell is set on the back of the electronic device, the camera portion of the electronic device passes through the second hollow portion 401 and the third hollow portion 402. At the same time, a detachable lens frame is provided on the edge of the third hollow portion 402 to enhance the aesthetics of the electronic device protective shell.

[0057] In some examples, there is a socket at the edge of the electronic device, and the electronic device protective shell needs to avoid the socket of the electronic device. On this basis, the inner shell edge also includes a socket portion, and a step structure 501 is provided on the outer side of the socket portion. At the same time, the outer shell edge also includes a contact portion 502. When the outer shell 201 is installed on the inner shell 101, the contact portion 502 is attached to the step surface of the step structure 501.

[0058] In actual implementation, the electronic device protective shell can be mounted on the back of the electronic device in two ways. First, the inner shell 101 is mounted on the back of the electronic device, and then the outer shell 201 is plugged and locked into the inner shell 101; or, first, the outer shell 201 is plugged and locked into the inner shell 101 to form a complete electronic device protective shell, and then the electronic device protective shell is mounted as a whole on the back of the electronic device. The wear-resistant inner shell 101 protrudes from the outer shell 201 on the back, angled position and side edges of the electronic device protective shell, which improves the wear resistance and corrosion resistance of the electronic device protective shell. At the same time, the inner shell 101 and the outer shell 201 jointly provide protection for the electronic device.

[0059] In the description of this specification, if the reference terms "one embodiment", "some examples", "some embodiments", "illustrative embodiment", "example", "specific example", or "some examples" appear, it means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0060] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
