To not affect the usage functions of mobile devices and without the need to frequently disassemble and assemble the protective covers, most protective covers are provided with corresponding buttons or openings for each functional part of the mobile device, so that users can, without removing the protective cover, press the buttons on the protective cover and trigger the corresponding buttons of the mobile device located inside the protective cover, thereby activating or deactivating their corresponding functions. Summary of the Invention

[0003] However, most protective covers fit onto the outside of mobile devices, so the buttons on the protective covers will also be aligned and fit onto the buttons on the mobile devices; in addition, in recent years, in order to pursue changes in shape or function, some buttons on protective covers are made of metal materials. Therefore, when a mobile device equipped with such a protective case accidentally falls, if it just hits the button, the metal button will easily hit the button on the mobile device, causing damage to the button on the mobile device or scratching its periphery.

[0065] To fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and in conjunction with the accompanying drawings, as follows:

[0066] Please refer to Figure 1, which is a preferred embodiment of the protective cover set of the mobile device of the present invention. The protective cover set of the mobile device includes a protective cover body 1 and at least one button 2, and the button 2 is detachably provided on the protective cover body 1.

[0067] Please refer to Figure 1 、 Figure 2 , the protective cover body 1 can be sleeved outside a mobile device (not shown in the figure). The mobile device can be, for example but not limited to, a mobile phone, a tablet computer, a smart watch or a wireless charging case for earphones, etc. Although the schematic diagram of this embodiment shows the protective cover body 1 for a mobile phone as an example, the present invention is not limited thereto. The protective cover body 1 has an inner surface 11, an outer surface 12, at least one through hole 13 and a ring flange 14. The inner surface 11 is opposite to the outer surface 12, and the through hole 13 penetrates the inner surface 11 and the outer surface 12. When the protective cover body 1 is sleeved outside the mobile device, the through hole 13 will be aligned with the button (such as a mechanical button or a metal thin film switch described below) on the mobile device; the ring flange 14 is located on the inner peripheral surface 131 of the through hole 13.

[0068] Please refer to Figures 3 to 5 , the button 2 includes a body 21, a pressing head 22 and an inner side part 23. The pressing head 22 and the inner side part 23 are respectively connected to two ends of the body 21. An inwardly concave annular groove 211 is provided on the outer peripheral surface of the body 21, so that the maximum width of the body 21 can be smaller than that of the pressing head 22 and the inner side part 23.

[0069] Please refer to Figure 6 , during assembly, the button 2 can be inserted into the corresponding through hole 13 with the inner side part 23, and the ring flange 14 of the protective cover body 1 can be aligned and inserted into the annular groove 211 of the button 2, so as to block the inner side part 23 by the ring flange 14 and prevent the button 2 from coming out of the corresponding through hole 13. At this time, the bottom end E of the inner side part 23 (the end of the button 2 facing the inside of the protective cover body 1) can be supported by the button 3 on the mobile device, so that the bottom surface of the pressing head 22 does not contact the ring flange 14, and at least a part of the pressing head 22 protrudes outside the through hole 13 for the user to press and operate.

[0070] Please refer to Figure 7 , when the user applies force to press the pressing head 22 of the button 2, the whole button 2 will displace in the direction of the inside of the protective cover body 1, and before the pressing head 22 abuts against the ring flange 14 or just abuts against the ring flange 14, the corresponding button 3 is triggered by the bottom end E of the inner side part 23, and a good feedback feel is obtained.

[0071] However, when the mobile device equipped with the protective sleeve body 1 accidentally drops and just hits the button 2, or the user presses the button 2 with improper force, so that the pressing head 22 of the button 2 receives an excessive pressing force, when the excessive pressing force causes the pressing head 22 to press against the annular flange 14, most of the pressing force can be immediately transmitted from the pressing head 22 to the annular flange 14, and then most of the pressing force is dispersed and absorbed by the protective sleeve body 1, so as to protect the corresponding button 3 on the mobile device from being damaged due to excessive force and prevent damage to the mobile device.

[0072] Therefore, for the mobile device protective sleeve set of the present invention, by enabling the annular flange 14 of the protective sleeve body 1 to be inserted into the annular groove 211 of the button 2 in alignment, the button 2 can disperse excessive pressing force to the protective sleeve body 1, effectively reducing the chance of damage to the button 3 on the mobile device or the area around the button 3. Among them, the protective sleeve body 1 and the button 2 can use the annular flange 14 and the annular groove 211 to make the transmission of force faster and more uniform, which is very helpful for improving the effect of dispersing force.

[0073] It is worth mentioning that in other embodiments, the perforation 13 of the protective sleeve body 1 can also be provided with an annular groove, and the pressing head 22 of the button 2 has an annular flange below, and the above effect can also be achieved by embedding the annular flange into the annular groove.

[0074] Please refer to Figures 3 to 5 , in addition to the above embodiments, in an embodiment of the present invention, the button 2 can also have a trigger member 24, and the trigger member 24 is disposed at the bottom end E of the inner side portion 23. Thus, when the button 2 is not subjected to a pressing force, the trigger member 24 can be supported by the corresponding button 3 on the mobile device, so that the pressing force applied to the pressing head 22 can be more accurately transmitted and triggered by the trigger member 24 to the corresponding button 3 on the mobile device. For example, the trigger member 24 can be integrally formed and connected to the inner side portion 23, or a convex body can be formed on the bottom surface of the inner side portion 23 by means of dotting, etc., and the present invention is not limited thereto.

[0075] In addition, in an embodiment of the present invention, the button 2 may be provided with an assembly hole 25. The assembly hole 25 may extend from the bottom end E of the inner portion 23 to the other end and may be formed in a state of not penetrating the pressing head 22. The trigger member 24 may be a rod T. The trigger member 24 may have an assembly portion 241 and an abutting portion 242. The assembly portion 241 may be inserted through the assembly hole 25, and the abutting portion 242 may protrude from the bottom end E of the inner portion 23. In this way, the button 2 may have a simple structure, be easy to manufacture and assemble, and different parts of the button 2 can be formed of different materials according to different requirements. For example, the body 21, the pressing head 22, and the inner portion 23 may be made of a metal material, and the trigger member 24 may be made of an elastic material such as silica gel or rubber. When the abutting portion 242 of the trigger member 24 triggers the corresponding button 3 on the mobile device, elastic deformation can occur, achieving the effects of improving the control accuracy and feel. Furthermore, when the pressing head 22 is pressed, the button 2 itself can also absorb part of the pressing force by the elastic deformation ability of the trigger member 24, further enhancing the effect that the overall mobile device protective cover group protects the button 3 on the mobile device or the periphery of the button 3 from being easily damaged. Among them, the depth of the assembly hole 25 can be set according to requirements. For example, considering the bonding strength with the assembly portion 241 of the trigger member 24 or leaving a gap, the depth of the assembly hole 25 in this embodiment can reach inside the pressing head 22, and in other embodiments, the depth of the assembly hole 25 can also only reach inside the body 21.

[0076] In an embodiment of the present invention, the button 2 may be conductive and is suitable for triggering a metal thin film switch. For example, the body 21, the pressing head 22, and the inner portion 23 of the button 2 may be integrally formed and connected structures and made of a conductive metal material. The trigger member 24 (the rod T) is made of a conductive rubber rod or a conductive silica gel rod, etc., so that the trigger member 24 can have elasticity and conductivity. In this way, please refer to Figure 1, the protective cover body 1 can be a mobile phone case, and the perforation 13 can be provided at the ring frame of the mobile phone case. For example, it is located on one of the long sides of the ring frame and adjacent to the outer end, so that the button 2 assembled in the perforation 13 can be conveniently pressed by the user when the mobile phone is placed horizontally. In addition, a screen film can be attached to the touch screen of the mobile phone installed on the protective cover body 1. The screen film has a film body and an invisible circuit layer. The invisible circuit layer is provided on the film body. The invisible circuit layer can correspond to a specific area of the touch screen and extend from the edge of the film body to form at least one touch part; the button 3 in this embodiment can be, for example, a metal dome membrane switch. The button 3 is connected to the touch part and is aligned with the perforation 13. Thus, when the user presses the button 2, the trigger member 24 (the rod T) can trigger the touch part of the invisible circuit layer when pressing against the button 3, forming an effect equivalent to pressing the touch screen of the mobile phone with a finger. Therefore, the mobile device protective cover set in this embodiment can form an e-sports mobile phone case suitable for playing mobile games. As long as the mobile phone is placed horizontally, the user can firmly hold the protective cover body 1. When playing games, for example, pressing the button 2 with the index finger is as comfortable and easy to operate as using a professional game controller, and the finger operating the button 2 will not block the game screen, which can speed up the game response time and bring a better game experience and usage convenience.

[0077] It is worth mentioning that when the button 3 is a metal dome membrane switch, in the embodiment where the trigger member 24 and the button 2 are integrally formed and connected, the button 2 can also be entirely made of the same conductive material. For example, the whole button can be made of a conductive metal material, or it can be entirely made of conductive silicone or rubber material, and the present invention is not limited thereto.

[0078] Please refer to Figure 3 , Figure 6 and Figure 7 , in an embodiment of the present invention, the button 2 can have a first receiving groove 26. The first receiving groove 26 can be recessed inward from the bottom end E of the inner side portion 23 and communicate with the assembly hole 25. A part of the abutting portion 242 of the trigger member 24 can be located in the first receiving groove 26 and partially protrude from the first receiving groove 26; preferably, the abutting portion 242 of the trigger member 24 can be located at the central position of the first receiving groove 26, but it is not limited thereto. In this way, when the elastic trigger member 24 is elastically deformed by pressing the trigger by its abutting portion 242, the first receiving groove 26 can accommodate the part of the abutting portion 242 that expands due to deformation, making the feedback feel of pressing the button 2 better.

[0079] In addition, in an embodiment of the present invention, the button 2 may further have a guiding inclined surface 27 located at the edge of the inner portion 23, such that the bottom end E of the inner portion 23 can be formed in a shape with a decreasing width; the first receiving groove 26 can be formed in an outwardly expanding shape, and the direction in which the bottom end E of the inner portion 23 forms a decreasing width is opposite to the direction in which the first receiving groove 26 expands outward. In this way, the guiding inclined surface 27 and the first receiving groove 26 can cause the bottom end E of the inner portion 23 to be formed in a shape with a decreasing wall thickness and be more likely to generate elastic deformation; during the process of inserting the button 2 into the corresponding through hole 13 with the inner portion 23, the bottom end E of the inner portion 23 can pass through the annular flange 14 more smoothly through the guiding inclined surface 27, and the inner portion 23 can be deformed and contracted into the first receiving groove 26, which helps to improve the smoothness of the operation when assembling the button 2.

[0080] Please also refer to Figure 2 , Figure 6 and Figure 7 , in an embodiment of the present invention, the section of the through hole 13 from the annular flange 14 to the inner surface 11 can be formed in an enlarged hole shape to form a second receiving groove 15. In this way, when the pressing head 22 receives a relatively large pressing force, the annular flange 14 will also undergo elastic deformation, and the second receiving groove 15 can provide a relatively large elastic deformation margin for the annular flange 14 and can also accommodate the portion of the inner portion 23 that expands due to deformation.

[0081] Please refer to Figure 8 , in addition to the above embodiments, in an embodiment of the present invention, the rod body T can be a metal rod with good electrical conductivity, such as a copper rod or the like. The rod body T can be loosely fitted and combined with the assembling hole 25 and be engaged with the assembling hole 25 to prevent the rod body T from easily coming out of the assembling hole 25. Moreover, there can be at least one elastic body 28 between the rod body T and the bottom surface 251 of the assembling hole 25, and the elastic body 28 can be, for example, a spring or a silicon / rubber cushion block or the like. In this way, when the pressing head 22 is pressed, part of the pressing force can be absorbed by the elastic body 28 of the button 2 itself. In other embodiments, the button 2 can also be formed by a method of inserting a copper rod into the assembling hole 25 and then injecting conductive glue for fixation, or other equivalent structures, and the present invention is not limited thereto.

[0082] Please refer to Figure 9, in addition to the above embodiments, in an embodiment of the present invention, a reinforcing structure 16 may be provided in the through hole 13 of the protective sleeve body 1. The reinforcing structure 16 is located between the annular flange 14 and the inner surface 11 of the protective sleeve body 1, and the reinforcing structure 16 is connected to the annular flange 14. For example, the reinforcing structure 16 may be in the form of a complete ring, a C shape, or several blocks connected below the annular flange 14. The reinforcing structure 16 can be used to enhance the structural strength of the annular flange 14, and at least a part of the reinforcing structure 16 can be orthogonally projected within the range of the pressing head 22, so as to effectively improve the effect of dispersing the force on the pressing head 22.

[0083] In addition, in an embodiment of the present invention, the bottom end E of the inner portion 23 may form a convex arc surface, the assembly hole 25 may be located at the most convex point of the convex arc surface, and a space S may be left between the rod body T and the hole bottom surface 251 of the assembly hole 25. In this way, the wrapping rate of the main body 21 on the rod body T can be improved, which helps to improve the combination stability of the two, and the rod body T can elastically deform into the space S at the top to provide buffering.

[0084] Please refer to Figures 10 to 12 , in addition to the above embodiments, in an embodiment of the present invention, when the button 3 is a metal thin film switch and the protective sleeve body 1 is sleeved outside the mobile device, the through hole 13 is aligned with the button 3, and the reinforcing structure 16 can abut against the outer edge 31 of the button 3 (outside the metal elastic sheet of the metal thin film switch), so that the reinforcing structure 16 can both position the button 3 and maximize the effect of enhancing the structural strength of the annular flange 14 and dispersing the force on the pressing head 22.

[0085] It is worth mentioning that the aforementioned mobile device protective sleeve set and the screen film can constitute the mobile device accessory set of the present invention, and the aforementioned mobile device accessory set can be combined with a mobile device to constitute the electronic device of the present invention; however, the electronic device and the mobile device accessory set of the present invention are not limited to only being applicable to the form of a mobile phone, nor are they limited to being used for playing mobile phone games. Any invention form that can implement the claims in the scope of the patent application of this case is covered by the present invention; for example, it is applied to the protective case of a smart watch, and the metal thin film switch connecting the screen film is triggered by the button of the mobile device protective sleeve set to quickly start or control certain functions, etc.

[0086] The present invention has been disclosed above with preferred embodiments. However, those skilled in the art should understand that these embodiments are only used to describe the present invention and should not be construed as limiting the scope of the present invention. It should be noted that all equivalent changes and substitutions to these embodiments should be considered as falling within the scope of the present invention.
