[0034] The present embodiment provides an electronic device protective shell, which has high versatility and can be used to protect screen-expandable electronic devices 100.

[0035] As shown in Figures 1 to 3 The electronic device protective shell includes a first shell 1, a second shell 2 and a limiting assembly 3.

[0036] As shown in Figure 3 The first shell 1 has a first groove 11, as shown in Figure 1As shown, the second shell 2 has a second groove 21, and the first shell 1 is connected to the second shell 2 through the limiting assembly 3, so that the first groove 11 and the second groove 21 can form the accommodating groove 10 in cooperation. In addition, the first shell 1 can slide relative to the second shell 2 in the width direction of the first shell 1 through the limiting assembly 3, so that the first groove 11 and the second groove 21 cooperate to form an accommodating groove 10 with variable size, thereby being capable of accommodating electronic products of different sizes. When the first shell 1 slides away from the second shell 2, the accommodating groove 10 gradually increases; when the first shell 1 slides towards the second shell 2, the accommodating groove 10 gradually decreases. It should be noted that the first shell 1 and the second shell 2 are respectively shells with notches, so as to form the accommodating groove 10.

[0037] The electronic device protective shell provided in the embodiment is connected by the first shell 1 and the second shell 2 through the limiting assembly 3, so that the first groove 11 of the first shell 1 and the second groove 21 of the second shell 2 can form the accommodating groove 10, and the electronic device 100 is installed in the accommodating groove 10 to be protected by the first shell 1 and the second shell 2. The first shell 1 can slide relative to the second shell 2, so that the size of the accommodating groove 10 can be adjusted, thereby the electronic device protective shell can be adjusted according to the size of the screen-expandable electronic device 100, has higher flexibility and universality, richer functions, and reduces the protection cost of the screen-expandable electronic device 100.

[0038] The specific structure of the limiting assembly 3 can be various, and in the embodiment, as shown in Figure 3 and Figure 4 The limiting assembly 3 includes a sliding groove 31 and a sliding block 32 that cooperate with each other. The first shell 1 is provided with the sliding groove 31, and the second shell 2 is provided with the sliding block 32. The sliding block 32 is slidingly connected in the sliding groove 31, so as to realize the sliding of the first shell 1 relative to the second shell 2. In addition, in the depth direction of the sliding groove 31, the sliding block 32 is limited in the sliding groove 31, so as to realize the clamping of the first shell 1 and the second shell 2 through the sliding groove 31 and the sliding block 32.

[0039] The shape of the sliding groove 31 can be set according to actual needs. In some embodiments, the sliding groove 31 is a T-shaped groove, a dovetail groove, etc., and correspondingly, the sliding block 32 is a T-shaped block, a dovetail block, etc., so that the sliding block 32 can be limited in the sliding groove 31.

[0040] In some optional embodiments, the first shell 1 and the second shell 2 are flexible members, and the first shell 1 and the second shell 2 are detachably connected. Please refer to Figure 3The first shell 1 is further provided with a mounting guide groove 12, which is in communication with one end of the sliding groove 31 and has a width greater than that of the sliding block 32, so that the sliding block 32 can slide into the sliding groove 31 through the guidance of the mounting guide groove 12, thereby realizing the assembly of the first shell 1 and the second shell 2. It should be noted that the width of the mounting guide groove 12 is greater than the maximum width of the sliding block 32, so that the sliding block 32 can be placed in the mounting guide groove 12. The length of the mounting guide groove 12 can be greater than, less than or equal to the length of the sliding block 32, which is not limited in the embodiment.

[0041] Optionally, as shown in Figure 2 , the first shell 1 includes a first bottom plate 14, a first end plate 15 and two first side plates 16. The two first side plates 16 are respectively connected to the two ends of the first bottom plate 14, and the first end plate 15 is connected to one side of the first bottom plate 14 and connected with the two first side plates 16 respectively, so as to form the first shell 1 with a notch. The first bottom plate 14 and the first side plate 16 respectively have a sliding groove 31, and the length direction of the sliding groove 31 is parallel to the width direction of the first bottom plate 14. In the embodiment, the first bottom plate 14 and the first side plate 16 respectively have a mounting guide groove 12.

[0042] Further optionally, please continue to refer to Figure 3 , the groove wall of the first recess 11 has a first boss 13, wherein the groove wall includes a bottom wall and a side wall.

One end of the mounting guide groove 12 is in communication with the sliding groove 31, and the other end of the mounting guide groove 12 extends to the first boss 13. The top surface of the first boss 13 is flush with the inner side surface of the second recess 21, specifically, the top surface of the first boss 13 is flush with the groove bottom wall and the groove side wall of the second recess 21, so as to better contact the electronic device 100, thereby improving the area and stability of supporting the electronic device 100.

[0043] Further, as shown in Figure 1 , the second shell 2 includes a second bottom plate 23, a second end plate 24 and two second side plates 25. The two second side plates 25 are respectively connected to the two ends of the second bottom plate 23, and the second end plate 24 is connected to one side of the second bottom plate 23 and connected with the two second side plates 25 respectively. The bottom surface on the other side of the second bottom plate 23 and the outer side surface of the second side plate 25 respectively have a sliding block 32, and the second end plate 24 is arranged opposite to the first end plate 15.

[0044] Optionally, the outer side wall of the second shell 2 has a second boss 22, which can abut against the side wall of the first shell 1 to limit the first shell 1 and the second shell 2. It should be noted that the electronic device protective case in the embodiment has multiple working states, for example, Figure 1 and Figure 7 the first working state provided by the embodiment, Figure 2 and Figure 8 the second working state provided by the embodiment. When the electronic device protective case is in the first working state, as shown in Figure 1 , the first shell 1 abuts against the second boss 22, at this time, the volume of the accommodating groove 10 reaches the minimum. It should be particularly noted that when the electronic device protective case is in the first working state, the slider 32 can be partially located in the installation guide groove 12, but will not be completely located in the installation guide groove 12, that is, when the second boss 22 abuts against the side wall of the first shell 1, at least part of the slider 32 is located in the sliding groove 31 to prevent the first shell 1 and the second shell 2 from being separated. When the electronic device protective case is in the second working state, the slider 32 slides to the end of the sliding groove 31 away from the installation guide groove 12, as shown in Figure 2 , the volume of the accommodating groove 10 reaches the maximum. In the embodiment, the second bottom plate 23 and the second side plate 25 each have a second boss 22.

[0045] In some optional embodiments, multiple limiting assemblies 3 are provided, and the multiple sliding grooves 31 are uniformly distributed on the first shell 1 to improve the stability of the first shell 1 and the second shell 2 when sliding. Correspondingly, the multiple sliders 32 are uniformly distributed on the second shell 2.
