Description

Technical Field

[0001] This utility model relates to the field of mobile phone case technology, specifically to a non-closed-loop mobile phone case metal bracket. Background Technology

[0002] Phone cases are decorative items used to protect or enhance the appearance of mobile phones. They have diversified with the increasing variety of phone brands and functions. Phone cases can be categorized by material, including PC cases, leather, silicone, fabric, hard plastic, leather cases, tempered glass metal cases, soft plastic, velvet, and silk. Phone cases not only enhance your phone's appearance but also protect it from drops, scratches, water, and shocks.

[0003] However, in existing technologies, when a mobile phone is magnetically charged, the bracket on the phone case is often made of metal and covers the magnetic charging area. This allows the magnetic charger to attract the bracket and the charging area together and charge the phone. However, the bracket on the phone case is often ring-shaped. When charging, the ring-shaped bracket generates an electromagnetic field after receiving current. This electromagnetic field can cause the charging components inside the phone to malfunction, leading to power outages and continuous overheating, which can damage the internal components of the phone. Summary of the Invention

[0004] The purpose of this utility model is to provide a non-closed-loop metal bracket for mobile phone cases, which has the advantage of disconnecting the mounting plate 201 from the support plate 203, preventing the formation of a circuit during charging and the generation of an electromagnetic field, which would cause power outages and continuous high temperatures during mobile phone charging, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-closed-loop mobile phone case metal bracket, comprising a case assembly, a bracket assembly, and an adjustment assembly. The case assembly is used to protect the mobile phone. The bracket assembly is disposed on the case assembly to support the mobile phone and prevent it from overheating during charging. The adjustment assembly is disposed on the bracket assembly for flipping and adjusting the support. The bracket assembly includes a mounting plate, a connecting plate, a support plate, two side plates, and a concave plate. The mounting plate is disposed inside the case assembly. The connecting plate is adhered to the mounting plate. The support plate is disposed on the mounting plate. Both side plates are fixedly mounted on the support plate. The concave plate is heat-fused onto the two side plates.

[0006] Furthermore, both the mounting plate and the support plate are provided with mounting notches, and the two mounting notches are respectively adapted to the connecting plate and the concave plate.

[0007] Furthermore, both the connecting plate and the concave plate are made of insulating plastic.

[0008] Furthermore, the housing assembly includes a protective shell and a mounting port, the mounting port being formed on one outer wall of the protective shell, and the mounting plate being fixedly installed inside the mounting port.

[0009] Furthermore, the adjustment assembly 3 includes a mounting port, a mounting bracket, a round rod, a ball bearing, a spring, a round plate, and a flip plate. The mounting port is opened on one outer wall of the mounting plate. The mounting bracket is rotatably mounted in the mounting port. The round rod is rotatably mounted on the mounting bracket. A groove is opened on the outer wall of the mounting bracket. The ball bearing is slidably mounted in the groove. The spring is fixedly mounted on the top inner wall of the groove. The bottom end of the spring is in contact with the ball bearing. The round plate is fixedly mounted on one outer wall of the mounting bracket. The flip plate is rotatably mounted on the round rod. The flip plate is fixedly connected to the support plate.

[0010] Furthermore, semi-circular grooves are evenly distributed on the inner wall of the mounting port, and the semi-circular grooves are adapted to the ball bearings.

[0011] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:

[0012] This invention uses a bracket assembly to attach the magnetic charger to the protective shell, covering the support plate and mounting plate. Since the mounting plate and support plate are made of metal and are conductive, the magnetic charger charges the phone's magnetic charging port through the mounting plate and support plate, forming a circuit with the magnetic charger, mounting plate, support plate, and the phone's magnetic charging port. Through the interaction of the connecting plate and the concave plate, the connecting plate disconnects the mounting plate, and the concave plate disconnects the support plate, preventing the mounting plate and support plate from forming a complete ring. During charging, when current flows through the mounting plate and support plate, because they are no longer a complete ring, they no longer form a circuit or magnetic field. Therefore, the phone is no longer affected by magnetic field interference, preventing power outages and continuous overheating. This invention has the advantage of disconnecting the mounting plate and support plate, preventing the formation of a circuit during charging that could generate an electromagnetic field and cause power outages and continuous high temperatures during phone charging.

[0013] This invention features an adjustment component. When a concave plate is engaged, it moves a support plate, which in turn moves a flip plate. The support plate and flip plate rotate around a circular rod. The support plate moves outside the mounting plate and unfolds to provide support. Twisting the support plate causes the flip plate and circular rod to twist, which in turn causes the mounting frame and circular plate to rotate within the mounting opening. As the mounting frame rotates, it causes ball bearings to roll within the mounting opening. During this rolling motion, the ball bearings are compressed, compressing a spring. The spring deforms under this compression and accumulates elastic force. When the ball bearings align with the semi-circular groove within the mounting opening, the spring releases its elastic force and pushes the ball bearings to move. The ball bearings then engage with the semi-circular groove, limiting the position of the rotating support plate. This design offers the advantages of adjusting the phone's support angle through flipping and adjusting the phone's position. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides, for example Figures 1-4 As shown, a non-closed-loop mobile phone case metal bracket includes a case assembly 1, a bracket assembly 2, and an adjustment assembly 3. The case assembly 1 is used to protect the mobile phone. The bracket assembly 2 is disposed on the case assembly 1 to support the mobile phone and prevent it from overheating during charging. The adjustment assembly 3 is disposed on the bracket assembly 2 for flipping and adjusting the support. The bracket assembly 2 includes a mounting plate 201, a connecting plate 202, a support plate 203, two side plates 204, and a concave plate 205. The mounting plate 201 is disposed inside the case assembly 1. The connecting plate 202 is adhered to the mounting plate 201. The support plate 203 is disposed on the mounting plate 201. The two side plates 204 are fixedly mounted on the support plate 203. The concave plate 205 is heat-fused onto the two side plates 204. More specifically, a magnetic charger is attached to the protective case 101 and covers the support plate 203 and the mounting plate 201. Because the mounting plate 201 and the The support plate 203 is made of metal and is conductive. When the magnetic charger is charging, it charges the magnetic charging port of the mobile phone through the mounting plate 201 and the support plate 203, forming a circuit between the magnetic charger, the mounting plate 201, the support plate 203, and the magnetic charging port on the mobile phone. Through the cooperation between the connecting plate 202 and the concave plate 205, the connecting plate 202 disconnects the mounting plate 201, and the concave plate 205 disconnects the support plate 203, so that the mounting plate 201 and the support plate 203 are no longer a complete ring. When charging, when the current passes through the mounting plate 201 and the support plate 203, since the mounting plate 201 and the support plate 203 are no longer a complete ring, they no longer form a circuit or magnetic field. The mobile phone is no longer affected by the magnetic field interference, which can cause power outages and continuous heat generation. It has the advantage of disconnecting the mounting plate 201 and the support plate 203, preventing the formation of a circuit and the generation of an electromagnetic field during charging, which can cause power outages and continuous high temperatures during mobile phone charging.

[0021] In addition, both the mounting plate 201 and the support plate 203 are provided with mounting notches, and the two mounting notches are respectively adapted to the connecting plate 202 and the concave plate 205.

[0022] In addition, both the connecting plate 202 and the concave plate 205 are made of insulating plastic.

[0023] like Figure 1 As shown, the housing assembly 1 includes a protective shell 101 and a mounting port 102. The mounting port 102 is opened on one side of the outer wall of the protective shell 101, and the mounting plate 201 is fixedly installed in the mounting port 102.

[0024] like Figure 1 As shown, in some embodiments, the adjustment assembly 3 includes a mounting port 301, a mounting bracket 302, a round rod 303, a ball bearing 304, a spring 305, a round plate 306, and a flip plate 307. The mounting port 301 is formed on one outer wall of the mounting plate 201. The mounting bracket 302 is rotatably mounted in the mounting port 301. The round rod 303 is rotatably mounted on the mounting bracket 302. A groove is formed on the outer wall of the mounting bracket 302. The ball bearing 304 is slidably mounted in the groove. The spring 305 is fixedly mounted on the top inner wall of the groove. The bottom end of the spring 305 is in contact with the ball bearing 304. The round plate 306 is fixedly mounted on one outer wall of the mounting bracket 302. The flip plate 307 is rotatably mounted on the round rod 303. The flip plate 307 is fixedly connected to the support plate 203. More specifically, when the concave plate 205 is engaged, the concave plate 205 drives the support plate 203 to move. The rotating plate 307 is moved, and the support plate 203 and the rotating plate 307 move and rotate around the round rod 303. The support plate 203 moves out of the mounting plate 201 and unfolds to provide support. Twisting the support plate 203 causes the rotating plate 307 and the round rod 303 to twist. The round rod 303 causes the mounting frame 302 and the round plate 306 to rotate within the mounting opening 301. When the mounting frame 302 rotates, it causes the ball bearing 304 to roll within the mounting opening 301. When rolling, the ball bearing 304 is squeezed, and the ball bearing 304 squeezes the spring 305. The spring 305 deforms under compression and accumulates elastic force. When the ball bearing 304 is aligned with the semi-circular groove in the mounting opening 301, the spring 305 releases its elastic force and pushes the ball bearing 304 to move. The ball bearing 304 moves and gets stuck in the semi-circular groove, limiting the rotation adjustment of the support plate 203. It has the advantages of rotating to adjust the support of the mobile phone and rotating to adjust the support angle of the mobile phone.

[0025] In some embodiments, semi-circular grooves are evenly distributed on the inner wall of the mounting port 301, and the semi-circular grooves are adapted to the ball bearings 304.

[0026] Working principle:

[0027] Step 1: Flip and adjust. Activate the concave plate 205. The concave plate 205 moves the support plate 203, which in turn moves the flipping plate 307. The support plate 203 and flipping plate 307 move and flip around the round rod 303. The support plate 203 moves out of the mounting plate 201 and unfolds to provide support. Twist the support plate 203. The support plate 203 moves the flipping plate 307 and the round rod 303 in a twisting motion. The round rod 303 then moves the mounting bracket 302 and the round plate 307 in a twisting motion. 6. The mounting bracket 302 rotates within the mounting port 301. When the mounting bracket 302 rotates, it drives the ball bearing 304 to roll within the mounting port 301. When rolling, the ball bearing 304 is squeezed, and the ball bearing 304 squeezes the spring 305. The spring 305 deforms under compression and accumulates elastic force. When the ball bearing 304 is aligned with the semi-circular groove in the mounting port 301, the spring 305 releases its elastic force and pushes the ball bearing 304 to move. The ball bearing 304 moves and gets stuck in the semi-circular groove, limiting the rotation adjustment support plate 203.

[0028] Step 2: Connect the charger. Attach the magnetic charger to the protective case 101, covering the support plate 203 and mounting plate 201. Since the mounting plate 201 and support plate 203 are made of metal and are conductive, the magnetic charger charges the phone's magnetic charging port through the mounting plate 201 and support plate 203. This forms a circuit between the magnetic charger, mounting plate 201, support plate 203, and the phone's magnetic charging port. Through the interaction between the connecting plate 202 and the concave plate 205, the connecting plate 202 disconnects the mounting plate 201, and the concave plate 205 disconnects the support plate 203. This prevents the mounting plate 201 and support plate 203 from forming a complete ring. During charging, when current flows through the mounting plate 201 and support plate 203, since they are no longer a complete ring, they no longer form a circuit or magnetic field. Therefore, the phone is no longer affected by magnetic field interference, preventing power outages and continuous overheating.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
