[0002] In today's society, mobile phones have become an indispensable tool for people in daily life. In order to protect mobile phones from being affected by external factors such as scratches, scratches and falls, mobile phone cases that match mobile phones have gradually become an indispensable choice for mobile phone users.

[0003] With the development and popularization of mobile phone shooting technology and functions, using mobile phones to shoot has become one of the most important functions of mobile phones. In daily use, the rear lens of mobile phones is prone to scratches or collisions. The main function of mobile phone cases is to protect the mobile phone body, but lacks protection for the rear lens of mobile phones.

[0004] Therefore, in order to solve this problem, many mobile phone cases that can protect the rear lens of mobile phones have appeared on the market. Such mobile phone cases usually set protective lenses at the hole position of the rear lens of the mobile phone, or protect the lens through a movable protective plate. However, mobile phone cases in the prior art usually use structures such as limiting protrusions to position and limit the protective plate at a special position. However, with long-term use, the limiting effect of the protective plate is poor, and the limiting plate is prone to shaking or displacement, etc., which leads to insufficient protection of the lens. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the utility model is to provide a mobile phone case to solve the problem that the protective plate of the mobile phone case in the prior art is easily shaken and displaced due to external influences, resulting in insufficient protection effect on the mobile phone lens.

[0010] Optionally, when the protection plate abuts against one side of the limiting frame in the width direction, the first magnetic attraction component and the second magnetic attraction component are staggered or partially overlapped.

[0011] Optionally, the mobile phone case further includes an isolation sheet, which is respectively arranged between the first magnetic attraction component and the middle case, and on a side of the second magnetic attraction component away from the middle case.

When the rear lens is not needed to shoot, the protective plate can be moved to the corresponding position of the through hole to cover the rear lens of the mobile phone for protection. When the rear lens of the mobile phone needs to be used, the protective plate is moved to completely expose the through hole. The protective plate can effectively protect the rear lens of the mobile phone and avoid scratches or damage. In actual use, through the mutual repulsion between the first magnetic suction member on the protective plate and the second magnetic suction member arranged in the middle of the width direction of the shell, the protective plate is forced to be pushed by the repulsion between the second magnetic suction member and the first magnetic suction member when passing through the second magnetic suction member, so that the protective plate moves to the desired position. On the other hand, when the protective plate moves to the desired position, the repulsive force between the second magnetic element and the first magnetic element will keep the protective plate relatively stable in the position and cannot move at will, thus preventing the protective plate from accidentally sliding due to shaking and other factors, thereby losing the protective function for the rear lens of the mobile phone. This setting can greatly improve the stability of the protective plate when the lens is opened or protected in the sinking groove, ensure the protection of the lens by the protective plate, and improve the protectiveness of the mobile phone case.

DETAILED DESCRIPTION

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0026] The present utility model embodiment provides a mobile phone shell 1000, such as Figure 1-3 As shown, the mobile phone case 1000 includes: a shell 100, a sinking groove 101 is provided on the shell 100, a through hole 301 is opened in the sinking groove 101, and the through hole 301 is used to correspond to the rear lens of the mobile phone, and a protective plate 200 that can be slidably connected to the sinking groove 101 is provided in the sinking groove 101, and a first magnetic component 202 is provided on the side of the protective plate 200 facing the shell 100, and a second magnetic component 303 is embedded on the side of the hand shell 100 facing the mobile phone, and the second magnetic component 303 is located in the middle of the shell 100 in the width direction, so that the protective plate 200 can be limited to one side of the shell 100 in the width direction under the repulsive force between the first magnetic component 202 and the second magnetic component 303.

[0027] The through hole 301 in the sinking groove 101 is arranged corresponding to the rear lens of the mobile phone, and the protective plate 200 can be moved in the sinking groove 101 to block or open the through hole 301. When the rear lens is not needed to shoot, the protective plate 200 can be moved to the corresponding position of the through hole 301 to cover the rear lens of the mobile phone for protection. When the rear lens of the mobile phone needs to be used, the protective plate 200 is moved to completely expose the through hole 301. The protective plate 200 can effectively protect the rear lens of the mobile phone to avoid scratches or damage. In actual use, through the mutual repulsion between the first magnetic suction member 202 on the protective plate 200 and the second magnetic suction member 303 arranged in the middle of the width direction of the shell 100, the protective plate 200 is forced to be pushed by the repulsion between the second magnetic suction member 303 and the first magnetic suction member 202 when passing through the second magnetic suction member 303, so that the protective plate 200 moves to the desired position. On the other hand, when the protective plate 200 moves to the desired position, the repulsive force between the second magnetic member 303 and the first magnetic member 202 will keep the protective plate 200 relatively stable in the position and cannot move at will, thus preventing the protective plate 200 from accidentally sliding due to shaking and other factors, thereby losing the protective function for the rear lens of the mobile phone. This arrangement can greatly improve the stability of the protective plate 200 when the lens is opened or protected in the sink 101, ensuring the protection of the lens by the protective plate 200 and improving the protectiveness of the mobile phone case 1000.

[0028] Specifically, the protective plate 200 can move along the width direction of the sinking groove 101 under the action of the repulsive force between the first magnetic component 202 and the second magnetic component 303. On the one hand, this design can make the protective plate 200 slide faster and smoother in the sinking groove 101. On the other hand, it can provide an additional stabilizing effect for the protective plate 200 at the position of opening the lens or protecting the lens, thereby preventing the protective plate 200 from losing protection for the mobile phone lens due to accidental sliding.

[0029] Specifically, the first magnetic member 202 is arranged on the side of the protection plate 200 facing the shell 100, so the first magnetic member 202 can move relative to the shell 100 following the protection plate 200, and the second magnetic member 303 is embedded in the side of the shell 100 away from the sinking groove 101, and is located in the middle of the width direction of the shell 100, so the second magnetic member 303 remains stationary relative to the shell 100. In the process of the protection plate 200 sliding relative to the shell 100, the first magnetic member 202 and the second magnetic member 303 can contact and overlap and generate a repulsive force, forcing the protection plate 200 to move to the edge of the sinking groove 101, or to the area where the first magnetic member 202 does not overlap with the second magnetic member 303.

[0030] Specifically, the shell 100 is provided with a through hole 301 for corresponding to the rear lens of the mobile phone, ensuring that the mobile phone lens can be used normally, while not affecting the overall structure of the mobile phone shell 1000.

[0031] In summary, the design of the above-mentioned protective plate 200 not only provides a protective function for the rear lens of the mobile phone, but also takes into account the operational convenience of the user during actual use, so that the user can conveniently use the mobile phone or carry the mobile phone without having to always pay attention to the relative position of the protective plate 200 in the sinking groove 101.

[0032] Further, refer to Figure 3 and Figure 4 The first magnetic member 202 has a first repulsive surface 2021 located on one side of the first magnetic member 202 , and the second magnetic member 303 has a second repulsive surface 3031 located on one side of the second magnetic member 303 . The first repulsive surface 2021 and the second repulsive surface 3031 are arranged opposite to each other.

[0033] The first repulsive surface 2021 of the first magnetic member 202 and the second repulsive surface 3031 of the second magnetic member 303 are arranged facing each other, which can ensure that when the first magnetic member 202 and the second magnetic member 303 intersect during the movement of the protective plate 200, a repulsive force is generated, so that the protective plate 200 can move more quickly and smoothly to the position of opening the lens or protecting the lens during the sliding process relative to the limit frame 500. When the protective plate 200 moves to the position of protecting the lens or opening the lens, the repulsive force between the first repulsive surface 2021 and the second repulsive surface 3031 can force the protective plate 200 not to shake or move due to external influences, thereby improving the stability of the protective plate 200 and strengthening the protective effect of the protective plate 200 on the mobile phone lens.

[0034] refer to Figure 3 A first receiving groove 201 and a shifting block 203 are provided on the protection plate 200 . The first magnetic attraction member 202 is provided in the first receiving groove 201 . The shifting block 203 is provided on a side of the protection plate 200 away from the first receiving groove 201 .

[0035] A first magnetic member 202 is disposed in the first receiving groove 201, and the first magnetic member 202 is directly disposed on the protective plate 200 through the first receiving groove 201, ensuring that the first magnetic member 202 will not fall off accidentally, thereby improving the stability of the connection between the first magnetic member 202 and the protective plate 200. The shifting block 203 can facilitate the user to move the protective plate 200, making the sliding of the protective plate 200 in the sinking groove 101 more convenient and convenient, and can also prevent fingers from directly contacting the mobile phone lens in the process of fiddling with the protective plate 200, thereby maintaining the cleanliness of the lens.

[0036] Specifically, the shift block 203 can facilitate the user to move the protective plate 200, which can improve the user's usage experience and comfort, making it more convenient for the user to protect the mobile phone lens or use the lens to take pictures, thereby improving the user's overall experience.

[0037] refer to Figures 2 to 4 The shell 100 includes a middle shell 300 and a limiting frame 500, the sinking groove 101 is located on the middle shell 300, the limiting frame 500 is arranged in the sinking groove 101, the protection plate 200 is arranged in the limiting frame 500, the through hole 301 is arranged at the bottom of the sinking groove 101, the middle shell 300 is provided with a second accommodating groove 302, and the second magnetic attraction member 303 is arranged in the second accommodating groove 302.

[0038] A limit frame 500 is provided on the middle shell 300. The limit frame 500 increases the structural strength of the mobile phone shell 1000, and also improves the stability of the sliding process of the protection plate 200, and improves the protective effect of the protection plate 200 on the mobile phone lens. The limit frame is arranged in the sinking groove 101, and the protection plate 200 is arranged in the limit frame 500, which can effectively provide a certain protection and limit effect for the protection plate 200, prevent the protection plate 200 from sliding beyond the range of motion, and ensure that external collision or friction will not cause damage to the protection plate 200.

[0039] Specifically, a second accommodating groove 302 is provided on the middle shell 300, and a second magnetic component 303 is provided therein, which is arranged opposite to the first magnetic component 202 on the protective plate 200, ensuring that the protective plate 200 can generate a repulsive force between the first magnetic component 202 and the second magnetic component 303 during the movement, thereby helping the protective plate 200 to remain stable in the position of opening the lens or protecting the lens.

[0040] refer to Figure 3 and Figure 4 When the protection plate 200 abuts against one side of the limiting frame 500 in the width direction, the first magnetic member 202 and the second magnetic member 303 are staggered or partially overlapped.

[0041] During the movement of the protection plate 200, the first magnetic member 202 in the first receiving groove 201 can have a large overlapping area with the second magnetic member 303 in the second receiving groove 302, so that a strong repulsive force can be generated between the first magnetic member 202 and the second magnetic member 303. In actual use, when the protection plate 200 slides relative to the limit frame 500, the first magnetic member 202 and the second magnetic member 303 will have an overlapping area, and a repulsive force will be generated between the overlapping parts, forcing the protection plate 200 to slide quickly relative to the limit frame 500. When the protective plate 200 moves to the position of protecting the lens or opening the lens, the first magnetic member 202 and the second magnetic member 303 are staggered or partially overlapped, so that there is no overlap between the first magnetic member 202 and the second magnetic member 303 or the overlapping area is small, so when the protective plate 200 wants to slide, it will not be able to slide due to the repulsive force generated by the overlapping part that will appear between the first magnetic member 202 and the second magnetic member 303, unless a greater external force is applied to the protective plate 200 to move it. Therefore, to a certain extent, the protective plate 200 can be limited to the position of opening the lens or protecting the lens through the repulsive force generated by the edge of the first magnetic member 202 and the edge of the second magnetic member 303.

[0042] refer to Figure 3 and Figure 4 The mobile phone case 1000 further includes an isolation sheet 600 , which is respectively arranged between the first magnetic member 202 and the middle shell 300 , and on a side of the second magnetic member 303 away from the middle shell 300 .

[0043] The isolation sheet 600 is disposed between the first magnetic member 202 and the middle shell 300 , and can physically isolate the first magnetic member 202 to prevent the first magnetic member 202 from causing damage to the middle shell 300 such as scratches.

[0044] The isolation sheet 600 is also arranged on the side of the second magnetic member 303 away from the middle shell 300. The isolation sheet 600 can not only protect the mobile phone from being scratched by the second magnetic member 303, but also isolate or reduce the magnetic field of the second magnetic member 303, thereby reducing the impact of the second magnetic member 303 on the mobile phone. The isolation sheet 600 can not only prevent the first magnetic member 202 and the second magnetic member 303 from causing damage to the shell 100 and / or the mobile phone, but also avoid or reduce the interference of the magnetic field of the second magnetic member 303 on the internal components of the mobile phone, thereby avoiding affecting the normal operation of the mobile phone.

[0045] Specifically, the first magnetic member 202 and the second magnetic member 303 can be prevented from affecting the housing 100 and / or the mobile phone by setting the isolation sheet 600. At the same time, the isolation sheet 600 can also structurally improve the connection stability between the first magnetic member 202 and the protective plate 200, and the connection stability between the second magnetic member 303 and the middle shell 300, ensuring that the connection between the first magnetic member 202 and the protective plate 200, and between the second magnetic member 303 and the middle shell 300 is more secure, and preventing the first magnetic member 202 and the second magnetic member 303 from loosening or falling off.

[0046] It should be noted that, because the first magnetic component 202 needs to slide relative to the middle shell 300 following the protective plate 200, and the first magnetic component 202 needs to generate a repulsive force with the second magnetic component 303, the isolation sheet 600 between the first magnetic component 202 and the middle shell 300 does not need to isolate the magnetic field of the first magnetic component 202, but only needs to isolate the positional relationship between the first magnetic component 202 and the middle shell 300 to avoid excessive friction between the first magnetic component 202 and the middle shell 300 during the movement of the protective plate 200, thereby affecting the normal sliding of the protective plate 200. Therefore, the isolation sheet 600 corresponding to the first magnetic component 202 needs to have a relatively smooth surface to reduce the friction during the sliding process, such as: Mylar sheet. The second magnetic component 303 is fixed relative to the middle shell 300, and the second magnetic component 303 is arranged on the side of the middle shell 300 close to the mobile phone. Therefore, in order to avoid the magnetic field of the second magnetic component 303 from interfering with the electronic components inside the mobile phone, the isolation sheet 600 arranged corresponding to the second magnetic component 303 needs to have the function of isolating the magnetic field, such as: copper sheet, iron sheet or wooden material, etc., to ensure the normal use of the mobile phone.

[0047] refer to Figure 1 , Figure 2 and Figure 5 The middle shell 300 is also provided with a back cover 700, and the back cover 700 is arranged adjacent to the limit frame 500. The back cover 700 is provided with a third accommodating groove 701, and a bracket assembly 800 is arranged in the third accommodating groove 701, and an avoidance groove 304 is opened on the middle shell 300 corresponding to the bracket assembly 800.

[0048] The back cover 700 is disposed adjacent to the limit frame 500, and the back cover 700 wraps part of the middle shell 300 to provide additional protection for the middle shell 300, so that the mobile phone case 1000 has better protection performance for the mobile phone and protects the mobile phone from scratches, falls and other damages. The back cover 700 is provided with a bracket assembly 800, and the bracket assembly 800 is located in the third receiving groove 701, so that the mobile phone case 1000 has a supporting function. The user can conveniently support the mobile phone in different occasions through the bracket assembly 800, which improves the convenience of using the mobile phone case 1000.

[0049] Specifically, the middle shell 300 is provided with an escape groove 304 corresponding to the bracket assembly 800, for escaping the bracket assembly 800. The escape groove 304 can ensure that the bracket assembly 800 can be stored in the third receiving groove 701 and the escape groove 304 when not in use, avoiding the inconvenience caused by the protrusion of the bracket assembly 800, and also contributing to the aesthetics of the overall appearance of the mobile phone shell 1000.

[0050] Specifically, the back cover 700 is disposed on the middle shell 300 , so that the back cover 700 and the limiting frame 500 can maintain levelness to a certain extent, thereby improving the integrity of the mobile phone shell 1000 .

[0051] Further, refer to Figure 5 The bracket assembly 800 includes a supporting piece 801 and a shielding plate 802 . The supporting piece 801 is disposed in the third receiving groove 701 , and the shielding plate 802 is rotatably connected to the supporting piece 801 .

[0052] The support sheet 801 is disposed in the third receiving groove 701, so that the connection between the bracket assembly 800 and the back cover 700 is relatively stable, ensuring that the bracket assembly 800 can still be firmly fixed on the mobile phone case 1000 through the support sheet 801 during use. The shielding plate 802 is rotatably connected to the support sheet 801. When the bracket assembly 800 needs to be used, the shielding plate 802 can be rotated to open the bracket assembly 800, thereby playing a supporting effect on the mobile phone.

[0053] Specifically, the rotatable connection design between the shielding plate 802 and the supporting plate 801 makes it easier for users to operate the bracket assembly 800. The user can easily adjust the angle of the shielding plate 802 relative to the supporting plate 801 without performing complicated operating steps.

[0054] refer to Figure 2 The mobile phone case 1000 further includes a protective frame 900, which is disposed in the middle case 300. The middle case 300 and the protective frame 900 form a receiving space for receiving the mobile phone.

[0055] The protective frame 900 is arranged in the middle shell 300, which can improve the horizontal structural strength of the mobile phone case 1000, effectively improve the protective performance of the mobile phone case 1000, and enable the mobile phone case 1000 to better absorb the impact force in the horizontal direction of the mobile phone, effectively reducing the impact on the mobile phone frame caused by falling and bumping. At the same time, after the mobile phone is covered with the mobile phone case 1000, the height of the protective frame 900 is slightly higher than the thickness of the mobile phone, so it can better protect the screen of the mobile phone when the mobile phone accidentally falls or the screen is turned upside down, avoid scratches or cracks on the mobile phone screen, and allow the mobile phone case 1000 to provide more comprehensive protection for the mobile phone. The protective frame 900 is arranged in the middle shell 300 and together form a storage space, which can ensure that the mobile phone case 1000 can accommodate the mobile phone stably and fit, avoid the situation that the mobile phone is loose or falls off, and ensure the safety of the mobile phone in daily use.

[0056] refer to Figure 2 and Figure 4 The bottom of the sinking groove 101 and the side of the mobile phone shell 1000 facing the mobile phone are respectively provided with anti-slip stripes 305.

[0057] The bottom of the sinking groove 101 is provided with anti-skid stripes 305, which can provide a certain friction force between the protective plate 200 and the housing 100 when the protective plate 200 slides to the position of protecting the lens or opening the lens, that is, when it abuts against one side of the width direction of the limit frame 500, so that the protective plate 200 can be better limited at the position. The anti-skid stripes 305 are arranged on the side of the back cover 700 facing the mobile phone, which can provide an anti-skid function between the mobile phone case 1000 and the mobile phone, increase the friction of the mobile phone case 1000 relative to the mobile phone, reduce the possibility of the mobile phone accidentally detaching and sliding in the mobile phone case 1000, and improve the protection of the mobile phone by the mobile phone case 1000. On the other hand, gaps will be formed between adjacent anti-skid stripes 305, which can reduce the contact area between the mobile phone case 1000 and the mobile phone, and the existence of the gaps can make the air circulation between the mobile phone case 1000 and the mobile phone better, so as to achieve a certain heat dissipation effect on the mobile phone.

[0058] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
