Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective case technology, and in particular to a protective case for electronic devices. Background Technology
[0002] CN110380751A discloses a protective shell, which includes a fixed base, a support member, and a cover member. The cover member can move relative to the fixed base between a first position and a second position. When the cover member moves to the first position, it is positioned above the second end of the support member, and the second end of the support member tends to spring up relative to the top surface, at which point the support is in a closed state. When the cover member moves to the second position, the second end of the support member disengages from the cover member and springs up relative to the top surface, at which point the support is in an open state. The support angle of the support member in this protective shell is limited and needs improvement. Utility Model Content
[0003] Therefore, this utility model needs to provide a protective case for electronic devices that provides support at a wider angle to meet the user's needs at different angles.

The support includes a rotating component disposed on the back of the case body and rotatably connected to the case body, and a support component hinged to the rotating component. Rotating the support component can change the angle between the support component and the rotating component.
[0005] Furthermore, the outer periphery of the rotating component is provided with a toothed ring, the shell body is provided with a lateral annular groove for accommodating the toothed ring, the toothed ring is constrained in the lateral annular groove, and the sidewall of the lateral annular groove is provided with an elastic protrusion, the elastic protrusion and the toothed ring being in a limited slip engagement.
[0006] Furthermore, the rotating component includes a central protrusion, and an annular receiving space is provided on the outer periphery of the central protrusion. The supporting component is a supporting ring, and the supporting component is placed in the receiving space after being folded.
[0007] Furthermore, the electronic device protective case also includes a first magnet for magnetic attraction with other items.
[0008] Furthermore, the first magnet is disposed in the cavity formed by the intermediate protrusion.
[0009] Furthermore, the support member is provided with a second magnet, which is used to magnetically fix the support member to the rotating member after it is folded.
[0010] Furthermore, the shell body includes a central base and protective arms that connect to the central base and extend to the four corners respectively, with corner guards formed at the ends of the protective arms.
[0011] Furthermore, the arm guard is detachably connected to the center seat.
[0012] Furthermore, the arm guard is connected to the center seat by screws.
[0013] The advantages of this invention are as follows: by rotating the rotating component, the supporting component can be rotated simultaneously, so that the supporting component is at the desired position angle relative to the shell body. Then, by opening the supporting component, the support angle of the shell body can be changed, thus providing support at a larger angle to meet the user's needs for use at different angles.

[0016] Figure 3 for Figure 2 Enlarged view of point A. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] This utility model provides a protective case for electronic devices, such as... Figure 1 and Figure 2 As shown, the electronic device protective case includes a case body 10 and a bracket 20. The bracket 20 includes a rotating member 21 disposed on the back of the case body 10 and rotatably connected to the case body 10 horizontally, and a support member 22 hinged to the rotating member 21. Rotating the support member 22 can change the angle between the support member 22 and the rotating member 21.
[0019] This invention allows the rotating component 21 to rotate simultaneously with the supporting component 22, positioning the supporting component 22 relative to the shell body 10 at the desired angle. By opening the supporting component 22, the support angle of the shell body 10 can be changed, thus providing support at a wider angle to meet the user's needs at different angles.
[0020] The support member 22 and the rotating member 21 can be connected together by a hinge 23.
[0021] In this embodiment, combined with Figure 3As shown, in order to provide rotational friction between the rotating component 21 and the shell body 10 and to prevent the rotating component 21 from rotating arbitrarily, the outer periphery of the rotating component 21 is provided with a toothed ring 210, and the shell body 10 is provided with a lateral annular groove 13 to accommodate the toothed ring 210. The toothed ring 210 is confined in the lateral annular groove 13, and the sidewall of the lateral annular groove 13 is provided with an elastic protrusion 14, which engages with the toothed ring 210 in a limited-slip engagement.
[0022] To facilitate the storage of the support member 22 after folding, the rotating member 21 includes a central protrusion 211, and an annular receiving space 212 is provided on the outer periphery of the central protrusion 211. The support member 22 is a support ring, and the support member 22 is placed in the receiving space 212 after folding.
[0023] The electronic device protective case also includes a first magnet 30 for magnetic attraction with other items. The first magnet 30 can fix the electronic device protective case to other items such as inside a vehicle or on a desktop, and can be used in conjunction with other items (including but not limited to the bracket 20).
[0024] The middle protrusion 211 forms a cavity 213 on the surface facing the shell body 10, and the first magnet 30 is disposed in the cavity 213 formed by the middle protrusion 211, so that the first magnet 30 is fixed.
[0025] The support member 22 is provided with a second magnet 221. The second magnet 221 is used to magnetically fix the support member 22 to the rotating member 21 after the support member 22 is folded, so as to prevent the support member 22 from easily rotating relative to the rotating member after the support member 22 is folded.
[0026] In this embodiment, the housing body 10 includes a central base 11 and protective arms 12 connected to the central base 11 and extending to the four corners. The ends of the protective arms 12 are formed with corner guards 121. This not only protects the electronic device but also reduces the weight of the housing body 10 and improves its aesthetic appearance. The protective arms 12 are detachably connected to the central base 11 for easy replacement. More specifically, the protective arms 12 are connected to the central base 11 by screws 16.
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
