[0001] The present invention relates to the technical field of smartphone cases, and more particularly to a smartphone case with an easily replaceable back cover. [Background technology]

[0002] Smartphones are common electronic devices, and people usually put smartphone cases on them, which are not only decorative items to make the smartphone more beautiful, but also protect the smartphone and provide effects such as drop prevention, scratch prevention, waterproofing, and shock resistance. The smartphone case includes a case body and a back panel, and the case body has an attachment cavity that fits the smartphone, the back case is removably attached to the back of the case body, and the decorative back panel has a removable structure, so that users can easily replace the back panel according to their needs and preferences.

[0003] However, due to the unreasonable structural design, the connection between the back panel and the case body is unstable, and it is inconvenient to attach and detach. In addition, the current smartphone itself is magnetic and can be magnetically attached to the smartphone holder, but after the smartphone case is attached, the magnetic adhesion effect between the smartphone and the smartphone holder is reduced, and the adhesion is unstable. It should be noted that the technology disclosed in this application may not be the prior art.

[0004] Therefore, focusing on the above problems, the present application proposes a new solution. Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, the present invention focuses on the deficiencies of the prior art and aims to provide a smartphone case whose back cover is easy to replace in order to solve the above problems. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention employs the following technical means.

[0007] A smartphone case with an easy-to-replace back cover comprises a case body and a back panel, the case body having an attachment cavity suitable for fitting a smartphone therein, the back panel being attached to the rear surface of the case body, the gap between the edge of the back panel and the case body being regulated by a snap-in structure, and a magnetic member being provided between the back panel and the rear surface of the case body, forming a magnetic fixing structure.

[0008] As a preferred technical means, the edge of the back panel is provided with at least one protrusion protruding outward, and the rear surface of the case body has a groove that engages with the protrusion, and the protrusion is engaged with the groove to form a snap-in protrusion.

[0009] As a preferred technical means, the back panel has the protrusions at both front corners, and the case body has corresponding grooves at both front corners on its rear surface.

[0010] As a preferred technical means, a recess is provided on the rear surface of the case body, the back panel is attached to the recess, and the groove is provided on the inner surface of the recess.

[0011] As a preferred technical means, the magnet member is provided on the rear surface of the case body.

[0012] As a preferred technical measure, the magnet member comprises an annular magnet member.

[0013] As a preferred technical means, the magnet member further comprises a block-shaped magnet member, and the block-shaped magnet member is located below the annular magnet member.

[0014] As a preferred technical measure, the four corners of the inner wall of the mounting cavity are each recessed outward to form a thin-walled portion. Effect of the Invention

[0015] Compared with the prior art, the present invention has obvious advantages and advantageous effects, which can be seen specifically from the above technical means, mainly: The cooperation of the snap-in structure and the magnet fixing structure not only allows the back panel and the case body to form a reliable connection structure, but also makes it very convenient to attach and detach the back panel. The snap-in structure is used to form a restricting effect to restrict the back panel from coming off the case body in a certain direction, thereby ensuring a reliable connection between the back panel and the case body, and then the magnet fixing structure is used to form the fixation, making it easy to attach and detach the back panel. With this structural feature, the back panel can be pre-customized with different appearances (patterns or shapes) according to needs. The present invention has multiple back panels with different appearances for users to use, and users can replace the back panels according to their needs and preferences. The attachment and detachment function can be formed only with the magnet member, but it should be noted that the connection is not secure after the back panel and the case body are attached. In addition, by providing a magnet member between the back panel and the back of the case body, the smartphone case itself can also be made magnetic, and the magnetism of the smartphone itself (if the smartphone has magnetism) and the magnetism on the smartphone case can be combined to ensure magnetic force, and when the smartphone (with the present invention attached) is magnetically attached to the smartphone holder, the stability of the attachment can be ensured. Of course, the present invention is not limited to smartphones that are magnetic in themselves, but can also be used with smartphones that are not magnetic in themselves, and there are no restrictions as they can be magnetically adsorbed and fixed onto the smartphone holder in the same way.

It will be understood that the specific embodiments described herein are merely for clarifying the technical contents of the present invention and are not intended to limit the present invention.

[0019] When an element is referred to as "fixed" to another element, it may be directly on the other element, or there may be intervening elements. It should be noted that when an element is referred to as "coupled" to another element, it may be directly coupled to the other element, or there may be intervening elements. As used herein, the terms "vertical," "horizontal," "left," "right," and similar expressions are used for descriptive purposes only.

[0020] 1 to 8, an embodiment of the present invention provides a smartphone case with an easy-to-replace back cover, which includes a case body 10 and a back panel 20. The case body 10 includes an attachment cavity 11 that is suitable for fitting a smartphone, the back panel 20 is attached to the back of the case body 10, and the gap between the edge of the back panel 20 and the case body 10 is regulated by a snap-in structure, and a magnet member is provided between the back panel 20 and the back of the case body 10 to form a magnet fixing structure.

[0021] The cooperation of the snap-in structure and the magnet fixing structure not only allows the back panel 20 and the case body 10 to form a reliable connection structure, but also makes it very convenient to attach and detach the back panel 20. The snap-in structure is used to form a restricting effect to restrict the back panel 20 from coming off from the case body 10 in a certain direction, thereby ensuring a reliable connection between the back panel 20 and the case body 10, and then the magnet fixing structure is used to form the fixation, making it easy to attach and detach the back panel 20. Due to such structural characteristics, the back panel 20 can be pre-customized with different appearances (patterns or shapes) according to needs. The present invention has a plurality of back panels 20 with different appearances for users to use, and users can replace the back panels 20 according to their needs and preferences. The attachment and detachment function can also be formed by only the magnet member, but it should be noted that the connection is not reliable after the back panel 20 and the case body 10 are attached. In addition, by providing a magnet member between the back panel 20 and the back surface of the case body 10, the smartphone case itself can be made magnetic, and the magnetic force can be secured by combining the magnetic force of the smartphone itself (if the smartphone is magnetic) with the magnetic force of the smartphone case, and the stability of the attachment can be secured when the smartphone (with the present invention attached) is magnetically attached to the smartphone holder. Of course, the present invention is not limited to smartphones that are magnetic, but can also be used with smartphones that are not magnetic, and there are no limitations because the smartphone can be magnetically attached to the smartphone holder and fixed in the same way.

[0022] In addition, at least one protrusion 21 protruding outward is provided on an edge of the back panel 20, and the back surface of the case body 10 has a groove 12 that engages with the protrusion 21, and the protrusion 21 engages with the groove 12 to form a snap-in protrusion 21. A restricting structure can be formed by the engagement of the protrusion-recess structure, and when actually assembling the back panel 20 and the case body 10, the back panel 20 is held by hand, the protrusion 21 is aligned with the groove 12, the protrusion 21 is fitted into the groove 12, and then the back panel 20 is attached to the back surface of the case body 10, and then the back panel 20 can be tightly attached to the case body 10 by the action of a magnet member.

[0023] In addition, the back panel 20 has the protrusions 21 at both corners on the front side, and the case body 10 has the grooves 12 at both corners on the front side of the back surface of the case body 10 corresponding to the protrusions 21. By providing the protrusions 21 and the grooves 12 at two positions on the same side, the engagement strength and stability can be further improved. Of course, in other embodiments, a plurality of (two or more) protrusions 21 can be provided at any positions on the left / right / rear side of the back panel 20, and a plurality of (two or more) grooves 12 can be provided at any positions on the left / right / rear side of the back surface of the case body 10 corresponding to the protrusions 21, and a snap-in restriction structure can be formed in the same manner. This embodiment is merely a preferred example, and is not limited thereto.

[0024] In addition, a recess 13 is recessed on the rear surface of the case body 10, the back panel 20 is attached to the recess 13, and the groove 12 is provided on the inner surface of the recess 13. The recess 13 provides an accommodation space for the attachment of the back panel 20, and improves the overall user experience of the present invention.

[0025] The magnet member is provided on the back surface of the case body 10, has magnetism, and can attract and fix the back panel 20.

[0026] The magnet member includes an annular magnet member 30. The annular structure reduces the amount of material used, while expanding the range of magnetic attraction and ensuring the reliability of magnetic adhesion.

[0027] In addition, the magnet member further includes a block-shaped magnet member 40, which is located below the annular magnet member 30. The block-shaped magnet member 40 can further improve the reliability of the magnetic adhesion.

[0028] In addition, the four corners of the inner wall of the mounting cavity 11 are each recessed outward to form a thin-walled portion 14. By providing the thin-walled portions 14 at the four corners of the inner wall of the mounting cavity 11, it is possible to provide the inner peripheral wall of the mounting cavity 11 with a good expansion and deformation effect. Since the thickness of the thin-walled portions 14 is small, the user can easily expand the mounting cavity 11, and it becomes easy to insert or remove the smartphone into or from the mounting cavity 11.

[0029] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made based on the principles of the present invention are within the protection scope of the present invention. [Explanation of symbols]
