Summary of the Invention

[0004] The main purpose of the present invention is to overcome the defects existing in the above-mentioned background technology and provide an electronic product protective case with a replaceable back plate.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A protective case for an electronic product with a replaceable back panel, comprising:

[0007] The back plate of the protective shell body is provided with a receiving slot for receiving the electronic device;

[0008] A replaceable external back panel, which is detachably mounted on the back panel of the protective case body via a magnetic assembly;

[0009] Wherein, the magnetic attraction component includes at least one of a whole magnetic area, a peripheral magnetic area or a peripheral magnetic area of ​​the camera frame arranged on the back plate of the protective shell body and / or the replaceable external back plate.

[0010] Furthermore, the entire magnetic area is: the back plate of the protective shell body and / or the replaceable external back plate are entirely made of magnetic material.

[0011] Furthermore, the peripheral magnetic area is: the magnets are continuously arranged along the outer edge of the back plate of the protective shell body and / or the replaceable external back plate.

[0012] Furthermore, the peripheral magnetic area of ​​the camera frame is: the magnet is arranged around the periphery of the camera opening of the replaceable external back panel.

[0013] Furthermore, a slot is provided on the side of the back panel of the protective shell body, and the replaceable external back panel is inserted into the slot and fixed by the magnetic attraction component.

[0014] Furthermore, the magnetic attraction component includes an electromagnet and is equipped with a power supply module;

[0015] The power supply module is an external rechargeable battery or is connected to an electronic device via a charging cable to obtain power and supply power to the electromagnet.

[0016] Furthermore, it also includes a group of magnets with the same polarity and mutually repelling each other, which are configured to form an air gap buffer layer between the replaceable external back plate and the back plate of the protective shell body;

[0017] The protective shell body is further provided with a fixing portion for limiting the displacement range of the replaceable external back panel.

[0018] Furthermore, it also includes a group of magnets with the same poles that repel each other and a group of magnets with different poles that attract each other, which are configured to form an air gap buffer layer between the replaceable external backplate and the backplate of the protective shell body, and achieve self-stable suspension through magnetic balance.

[0026] Furthermore, the removal mechanism is arranged at the camera frame or any hollow area of ​​the replaceable external back panel.

[0027] The present invention has the following beneficial effects:

[0028] This invention proposes a protective case for electronic products with a replaceable back panel. A magnetic assembly allows for a detachable connection between the replaceable external back panel and the back panel of the protective case itself, allowing users to update the style or expand functionality without having to replace the entire case, thus reducing resource waste. The magnetic assembly offers a variety of magnetic area settings (such as a full magnetic area, a peripheral magnetic area, and a magnetic area around the camera frame), allowing for flexible selection based on actual needs. This not only meets the magnetic attraction requirements in different scenarios, but also avoids affecting the wireless charging function of the electronic device itself.

[0029] The slot design on the side of the back panel of the protective case allows the replaceable external back panel to be inserted through the slot and fixed by a magnetic component, providing guidance for the installation process and improving the accuracy and convenience of installation.

[0030] The magnetic component uses an electromagnet and is equipped with a power supply module (such as installing an external rechargeable battery or connecting an electronic device to draw power through a charging cable). The magnetic force can be turned on and off by controlling the on and off of the current, further enhancing the flexibility of use and allowing users to quickly replace the back panel as needed.

[0031] A group of magnets with similar poles that repel each other is provided to form an air gap buffer layer between the replaceable external back panel and the back panel of the protective case body. Self-stable suspension is achieved by combining with the fixed part or through the magnetic balance between the group of magnets with similar poles that repel each other and the group of magnets with different poles that attract each other, effectively improving the anti-fall performance of the protective case and providing more reliable protection for electronic equipment. The presence of the air gap buffer layer effectively reduces the impact of external shocks on electronic equipment.

[0032] The design of a removable mechanism (e.g., a grip or lever-type release) for the replaceable external back panel allows for easy removal using a pull or lever mechanism, making operation simple and effortless. Furthermore, the grooved design of the release section further optimizes the user's grip and makes the removal process smoother. The release mechanism can be located on the camera frame or in any other cutout area, ensuring a seamless aesthetic while facilitating user operation and significantly improving the user experience.

[0033] Other beneficial effects of the embodiments of the present invention will be further described below. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0049] See Figures 1 to 11c , an embodiment of the present invention provides an electronic product protective case with a replaceable back panel, comprising a protective case body back panel 1 and a replaceable external back panel 2. The protective case body back panel 1 is provided with a receiving slot for accommodating electronic equipment, which can firmly wrap the electronic equipment therein to provide basic protection. In the present invention, the replaceable external back panel 2 is detachably mounted on the protective case body back panel 1 by a magnetic component, thereby realizing flexible replacement of the back panel. The magnetic component includes at least one of a whole magnetic area, a peripheral magnetic area, or a camera frame peripheral magnetic area arranged on the protective case body back panel 1 and / or the replaceable external back panel 2.

[0050] In some embodiments, the magnetic component can be configured in a variety of ways. For example, the first is a whole magnetic area, such as Figure 1 As shown, the protective shell body back plate 1 and / or the replaceable external back plate 2 are made of magnetic material as a whole, so that the entire back plate surface is magnetic and can generate suction evenly to ensure the stability of the installation of the replaceable external back plate 2. The second type is the peripheral magnetic area, such as Figure 2 As shown, the magnets 3 are continuously arranged along the outer edge of the back plate 1 of the protective case body and / or the replaceable external back plate 2. This method can effectively avoid affecting the wireless charging function of the electronic device itself while ensuring the adsorption force. The third type is the magnetic area outside the camera frame, such as Figure 3 As shown, the magnet 3 is arranged around the periphery of the camera opening of the replaceable external back plate 2, providing targeted adsorption force, which does not affect the use of the lens while achieving the fixation of the back plate.

[0051] In some embodiments, in the installation structure, a slot 4 is provided on the side of the back plate 1 of the protective shell body. Figure 4 As shown, the replaceable external back panel 2 is inserted through the slot 4 and fixed by a magnetic assembly. The presence of the slot 4 provides precise guidance for the installation process, so that the replaceable external back panel 2 can be installed quickly and accurately, thereby improving the convenience and accuracy of the installation.

[0052] In some embodiments, the magnetic attraction component can also use an electromagnet and be equipped with a power supply module 5, such as Figure 5As shown, the power supply module 5 can be equipped with an external rechargeable battery for independent power supply. Alternatively, it can be connected to an electronic device via a charging cable to save additional power. By controlling the current flow, the magnetic force can be turned on and off, allowing users to quickly replace the back panel as needed, enhancing flexibility.

[0053] In some embodiments, in order to improve the drop resistance of the protective shell, the protective shell is further provided with a group of magnets 6 with the same polarity and mutually repelling magnets. Figure 6 As shown, the same-pole mutually repelling magnet group 6 is configured to form an air gap buffer layer 7 between the replaceable external back plate 2 and the protective shell body back plate 1. At the same time, the protective shell body is further provided with a fixing portion 8 for limiting the displacement range of the replaceable external back plate 2, ensuring the stability of the back plate position while providing buffering. In another embodiment, as Figure 7 As shown, a like-pole repelling magnet group 6 and an opposite-pole attracting magnet group 9 are provided at the same time, and an air gap buffer layer 7 is formed between the replaceable external back panel 2 and the back panel 1 of the protective shell body through configuration, and self-stable suspension is achieved through the magnetic balance of the like-pole repelling magnet group 6 and the opposite-pole attracting magnet group 9, thereby ensuring the stability of the back panel without the need for a fixed part, and effectively reducing the impact of external shocks on the electronic equipment.

[0054] In some embodiments, the replaceable external back panel 2 is provided with a removal mechanism 10, such as Figure 8 For example, the removal mechanism can include two forms. The first form is a hand grip 11, which is connected to the external back plate 2 body through a connecting portion, such as Figure 9a-9b As shown, when the hand grip is pulled, the external back panel 2 can be driven to separate from the protective shell body back panel 1. The second type is a separation portion 12, which is provided with a lever portion 13 extending to the bottom surface of the external back panel 2, and the middle of the separation portion 12 is rotatably connected to the end of the external back panel 2, as shown in FIG. Figure 10a-Figure 10b As shown, when the separation portion 12 is pulled, the lever portion 13 rotates downward, using the principle of leverage to press down the protective case body back panel 1 and pry the external back panel 2 off the protective case body back panel 1, so that the external back panel 2 is separated from the protective case body back panel 1. Further preferably, the separation portion 12 may further have a groove 14 for the user's finger to pull, thereby optimizing the user's grip and operating convenience.

[0055] In some embodiments, the removal mechanism 10 can be set at the camera frame of the replaceable external back plate 2 or any hollow area, such as Figure 11a-Figure 11c As shown, it does not affect the overall appearance of the protective case and is convenient for users to operate.
