DETAILED DESCRIPTION OF THE INVENTION

[0037] To facilitate understanding of the purpose, characteristics and effects of the present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided as below.

[0038] Referring to FIG. 1, it relates to a mobile device protective case set of a preferable embodiment of the present disclosure, the mobile device protective case set includes a main frame 1 and an assembling component 2 that can be assembled to each other. The mobile device protective case set may be placed on the outside of a mobile device (not shown in the figure), the mobile device may, for example, but not be limited to, a mobile phone, a tablet, a smartwatch or a wireless charging case for earbuds; although the drawings of the present embodiment are presented as an example of a mobile device protective case set for a mobile phone, the present disclosure is not limited thereto.

[0039] Among them, taking a non-folding upright mobile phone as an example, the mobile device usually has a display screen, a side edge and a back side. The display screen is opposite to the back side, and the side edge can be connected between the display screen and the back side. When the mobile device protective case set is assembled on the mobile device, the main frame 1 can surround and clad the side edge of the mobile device. The present disclosure may optionally define a direction orthogonal to a plane of the display screen as a Z direction, and a place where the display screen is located is faces toward a forward direction, and a place where the back side is located faces toward a backward direction. When the user faces the mobile device and operates the touch screen, the left and right directions are defined as a X direction and the up and down directions are defined as a Y direction according to the direction when the user operates the touch screen.

[0040] Referring to FIG. 1 to FIG. 6, the cross-section of the main frame 1 of the present embodiment on the XY plane can be generalized as a hollow rectangle, but is not limited thereto. The main frame 1 has an inner circular surface 11 and an outer circular face 12, and is enclosed by the inner circular surface 11 to define a space S suitable for accommodating a mobile device E. The main frame 1 also has a front flange 13 and a back flange 14 opposite to each other in the Z direction, and the front flange 13 and the back flange 14 respectively protrude from the inner circular surface 11 towards the space S, so that the cross-section of the main frame 1 on the XZ plane can be generalized to a C shape (as shown in FIG. 3), and thus the side edge of the mobile device E assembled into the space S can be limited between the front flange 13 and the back flange 14 (as shown in FIG. 5).

[0041] In addition, the back flange 14 has a device abutting surface 141 facing forward, which is suitable for the back side of the mobile device E to abut (as shown in FIG. 5). The main frame 1 also has at least one positioning portion 15, which is located at the device abutting surface 141, the assembling component 2 has a base portion 21 and at least one clamping portion 22, the clamping portion 22 is disposed at the local outer peripheral edge of the base portion 21, and the clamping portion 22 is suitable for combining with the positioning portion 15.

[0042] In the present embodiment, when using a mobile device protective case set, the user may first assemble and combine the assembling component 2 to the main frame 1, and utilize the corresponding clamping portion 22 and the positioning portion 15 to make the assembling component 2 stably assembled in the main frame 1. The mobile device E is then assembled into the space S through the front flange 13, so that the device abutting surface 141 (as shown in FIG. 5) of the back flange 14 and a facing forward surface 221 (as shown in FIG. 6) of the clamping portion 22 can abut against the back side of the mobile device E, and thus the mobile device E will not shake in the space S.

[0043] Alternatively, the user may not assemble the assembling component 2, but directly assemble the mobile device E into the space S through the front flange 13. In this way, even if the clamping portion 22 of the assembling component 2 is missing, the back side of the mobile device E can still abut against the device abutting surface 141 of the back flange 14, and the same shaking is not generated in the space S, and can be blocked by the back flange 14, so as to ensure that the mobile device E cannot come out of the back side of the main frame 1.

[0044] Therefore, when using the mobile device protective case set in the present embodiment, whether the main frame 1 is assembled with the assembling component 2 or not, the mobile device E can be stably assembled, and the mobile device E is not easy to shake in the main frame 1, so the user can choose whether to assemble the assembling component 2 according to the demand, so as to meet different protection or modeling matching requirements. In addition, in the case of damage or loss of the assembling component 2, the user can still use the main frame 1 alone to provide protection effect for the mobile device E, without replacing the main frame 1 that is still functionally good, which can reduce unnecessary waste of resources.

[0045] It is worth noting that the present disclosure does not limit the form of the assembling component 2. For example, the assembling component 2 of the present embodiment may be a backplate, so the base portion 21 can be in the form of a plate, and after the assembling component 2 is connected to the main frame 1, the base portion 21 can shade all or part of a back opening of the main frame 1, that is, the base portion 21 can block the back side of the mobile device E and protect the back side of the mobile device E from being damaged. In other embodiments, the assembling component 2 may also be a structure similar to the traditional decorative strip, whereby, whether the main frame 1 is assembled with the assembling component 2 or not, the back side of the mobile device E can have a larger part of the exposed area, so that the assembling component 2 can be matched with the main frame 1 to produce more diverse decorative effects.

[0046] In addition, referring to FIG. 1 and FIG. 8, in one embodiment of the present disclosure, the back flange 14 can be composed of four segments. The four segments in the present embodiment may include two long segments and two short segments, a length of the long segment is greater than a length of the short segment, so as to conform to the form of most current mobile devices such as mobile phones or tablet computers; in other embodiments, the number of the long segments and/or the short segments is not limited, or each segment can also be made to be of equal length, the present disclosure does not limit thereto. In addition, the present embodiment can optionally dispose at least one positioning portion 15 on the four segments respectively, so that when the assembling component 2 is assembled on the main frame 1, the assembling component 2 can be stably combined with the main frame 1 in the X-axis direction and the Y-axis direction to prevent the assembling component 2 from loosening from the main frame 1, and the present disclosure also includes an aspect in which at least one of the four segments is provided with the positioning portion 15.

[0047] Referring to FIG. 7 and FIG. 8, in one embodiment of the present disclosure, the device abutting surface 141 of the back flange 14 can be flush with the facing forward surface 221 of the clamping portion 22; that is to say, the device abutting surface 141 and the surface 221 fail to form a segment difference in the Z direction in substance. In this way, under the condition that the back side of the mobile device is basically formed in a plane, when the main frame 1 is assembled with the assembling component 2, the mobile device protective case set of the present embodiment can make the device abutting surface 141 of the back flange 14 and the facing forward surface 221 of the clamping portion 22 can be jointly supported on different parts of the back side of the mobile device; in the present embodiment, the different parts of the back side of the mobile device refer to a continuous edge of the outer periphery the back side of the mobile device. In other embodiments, as long as the device abutting surface 141 and the surface 221 can jointly support the back side of the mobile device, the present disclosure does not limit the form of the back side of the mobile device.

[0048] Referring to FIG. 6, in addition to the above embodiments, in one embodiment of the present disclosure, the inner circular surface 11 is preferably substantially smoothly connected with the facing forward surface 221 of the clamping portion 22. In this way, when the mobile device protective case set in the present embodiment is assembled with the mobile device E, the inner circular surface 11 of the main frame 1 can surround and clad the side edge of the mobile device E, and the junction between the inner circular surface 11 and the surface 221 can also smoothly transit to the back side of the mobile device E to conform to the side edge and the back side of the mobile device E, which can enhance the cladding property and binding stability of the mobile device protective case set to the mobile device E.

[0049] Similarly, referring to FIG. 3 and FIG. 5, in one embodiment of the present disclosure, the outer periphery 211 of the base portion 21 is preferably substantially smoothly connected with the device abutting surface 141 where the clamping portion 22 is not provided; that is to say, the outer periphery 211 and the device abutting surface 141 fail to form a segment difference in the Z direction. In this way, the mobile device protective case set in the embodiment can also jointly abut against the back side of the mobile device E at the junction of the device abutting surface 141 and the outer periphery 211 of the base portion 21, so that the cladding property and binding stability of the mobile device protective case set to the mobile device E can be enhanced.

[0050] Referring to FIG. 3, in addition to the above embodiments, in one embodiment of the present disclosure, on the XY plane, a protruding amplitude of the back flange 14 towards the space S may be greater than a protruding amplitude of the front flange 13 towards the space S; that is, referring to FIG. 9 and when looking down at the main frame 1, the back flange 14 can be seen. In this way, the main frame 1 of the present embodiment can form a protective structure to prevent the mobile device from coming out of the back side by a simple structure, and the back flange 14 can also be used to set the positioning portion 15, which has the effects such as improving the manufacturing convenience of the main frame 1 and the assembly convenience of the main frame 1 and the assembling component 2.

[0051] Referring to FIGS. 1, 4, 7 and 10, the shape of the positioning portion 15 can be matched with the shape of the clamping portion 22, so that the clamping portion 22 can be detachably combined with the corresponding positioning portion 15. For example, as shown in FIG. 4, in one embodiment of the present disclosure, the positioning portion 15 may have a groove 151, a hook portion 152 and a gap 153. The groove 151 is formed by the backward recess of the device abutting surface 141 towards the Z-axis, the hook portion 152 is located between the groove 151 and the space S, and the hook portion 152 can protrude forward from the bottom end of the groove 151. A height of a free end of the hook portion 152 on the Z-axis is lower than that of the device abutting surface 141 where the positioning portion 15 is not provided, and the gap 153 is formed thereby. As shown in FIG. 6, the clamping portion 22 can form a clamping hook to pass through the gap 153 and engage in the groove 151. In this way, the main frame 1 and the assembling component 2 can be combined by a structure that is easy to form and easy to disassemble, and has the effects of improving manufacturing convenience and assembly convenience and efficiency. In other embodiments, the positioning portion 15 and the clamping portion 22 can also form the corresponding structures of other different forms to position each other; for example, referring to FIG. 11, the positioning portion 15 can form a stepped shape, and the clamping portion 22 corresponds to form a flat plate shape so that it can be positioned in the positioning portion 15 by lapping, or other forms of structures, etc., and the present disclosure does not limit thereto.

[0052] Referring to FIG. 1, in addition to the above embodiments, in one embodiment of the present disclosure, the number of clamping portions 22 of the assembling component 2 may be plural, for example, the shorter upper and lower edges of the base portion 21 are respectively provided with one clamping portion 22, the longer left and right edges of the base portion 21 are respectively provided with a plurality of clamping portions 22, and the plurality of clamping portions 22 at the same left edge or right edge can be preferably disposed at equal intervals; the number and setting positions of the positioning portions 15 of the main frame 1 correspond to the clamping portions 22 of the assembling component 2. That is, the two short segments of the back flange 14 respectively correspond to the upper and lower edges of the base portion 21, so that the short segments of the back flange 14 can be optionally provided with one positioning portion 15 at the middle position; the two long segments of the back flange 14 respectively correspond to the left and right edges of the base portion 21, so that the long segments of the back flange 14 can be provided with two positioning portions 15, so as to improve the limiting effect of the main frame 1 on the assembling component 2, and avoid the assembling component 2 from loosening relative to the main frame 1. In this way, the binding stability and manufacturing convenience of the main frame 1 and the assembling component 2 can be taken into account. Among them, considering the product reliability requirements after the assembling component 2 is assembled to the main frame 1, the two positioning portions 15 disposed at the long segment of the back flange 14 are preferably disposed at intervals, which means that the two positioning portions 15 of the long segment of the back flange 14 are bridging with a device abutting surface 141.
