Description

Technical Field

[0001] This utility model relates to the field of mobile phone case technology, specifically a mobile phone case with an adjustable support structure. Background Technology

[0002] With the development and popularization of mobile phones, mobile phones have become an indispensable part of life. In order to protect the phone or enhance its appearance, most users choose to use a phone case. A phone case with a stand is also a type of phone case. It has the dual functions of protection and support, making it convenient to watch videos, play games, use hands-free navigation, etc.

[0003] However, common phone cases with stands are usually complex in structure, large in size, and not aesthetically pleasing, making it difficult to meet user needs. To overcome these shortcomings, existing technology (Chinese patent application number 202323639486.7, application date 2023-12-28) describes a phone case that uses the relative rotation between the turntable and the back panel, and between the support block and the turntable, to achieve a wider adjustment range and make it more convenient for users to adjust and use flexibly. This phone case has a simple structure, and when the stand is not used, the support block can be completely folded into the mounting groove of the back panel, saving more space and making the phone case smaller. In the folded state, the outer periphery of the support block fits perfectly with the wall of the mounting groove, making it more aesthetically pleasing. However, in actual operation, due to structural limitations, the support distance of the above-mentioned phone case is relatively limited. Therefore, when actually supporting the phone case, the tilt angle is relatively large, which is inconvenient for users to view.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a phone case with an adjustable support structure that can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile phone case with an adjustable support structure to solve the problem mentioned in the background art that, due to structural limitations, the support distance of the aforementioned mobile phone case is relatively limited during actual operation, resulting in a large tilt angle when actually supporting the mobile phone case, which is inconvenient for users to view.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone case with an adjustable support structure, comprising a mobile phone case body, an annular mounting groove at the rear end of the mobile phone case body, and a rotating seat rotatably disposed on the inner side of the mounting groove; a support seat is rotatably connected to the top end face of the rotating seat via a damping shaft, and an extension seat is disposed below the support seat, and the support seat and the extension seat form a complete annular structure; movable strips are fixedly connected to both ends of the extension seat, and movable grooves are provided inside both sides of the support seat, with the movable strips correspondingly sliding on the inner side of the movable grooves; a connecting horizontal plate is fixedly connected between the two ends of the support seat, and a limiting component is provided on the inner side of the support seat and the connecting horizontal plate for relative limiting and fixing of the movable strips and the movable grooves.

[0007] Preferably, the front inner edge of the main body of the phone case is formed with an edge protrusion to stably fasten the phone to the inside of the main body of the phone case, and the rear end of the main body of the phone case is formed with a lens protrusion at the outer edge of the phone lens to improve the protection effect of the phone lens.

[0008] Preferably, the outer wall of the rotating base is formed with a limiting protrusion, and the inner wall of the mounting groove is provided with a limiting slide groove that matches it, so as to ensure the stable effect of the rotating base being rotated and installed on the main body of the mobile phone case.

[0009] Preferably, the extension base has a pull opening at the bottom center, allowing the user to hook their fingers onto the pull opening to rotate and pull up the extension base and support base. Anti-slip pads are fixedly adhered to the bottom walls on both sides of the pull opening to increase the friction between the extension base and the mobile phone placement surface.

[0010] Preferably, the end of the moving strip is formed with a protrusion, and the moving groove is composed of two grooves that are respectively adapted to the size of the moving strip body and the protrusion, so that the moving strip can slide within a limited range along the moving groove.

[0011] Preferably, the limiting component includes multiple slots formed on one side of the two moving strips that are close to each other, and the slots are vertically and evenly distributed. The inner side of the connecting cross plate is slidably connected to two symmetrically distributed moving rods, and one end of each of the two moving rods is inserted into one of the slots on both sides. A spring is fixedly connected between the two moving rods.

[0012] Preferably, each of the two movable levers has a toggle portion formed on the side where they are close to each other, and the toggle portion protrudes from the end face of the connecting cross plate so as to push the two movable levers closer together by the toggle portion.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This kind of mobile phone case with adjustable support structure can be stably supported by rotating and pulling up the support base and extension base to form a certain angle with the rotating base. At this time, the damping shaft friction self-locks, and the main body of the mobile phone case and the mobile phone can be stably supported. By using the cooperation of the moving strip, moving groove, connecting horizontal plate and limiting component, the limiting component is used to fix the moving strip and moving groove relatively, so that it can remain stable after adjustment, and then the tilt angle of the mobile phone is reduced, so that the user can view and use it. The specific contents are as follows: (1) By rotating and pulling up the support base and extension base to form a certain angle with the rotating base, and then by the self-locking effect of the friction force generated by the damping shaft, the main body of the mobile phone case and the mobile phone can be stably supported at a certain angle. At the same time, by rotating the rotating base, different support effects for the mobile phone in the horizontal or vertical direction can be achieved.

[0014] (2) When the support distance is limited and the tilt angle of the mobile phone is too large, the extension seat can be pulled away from the support seat. The moving bar moves along the moving groove in sync. When the support distance is adjusted to be appropriate, the limiting component is used to fix the moving bar and the moving groove relatively, so that the adjusted length remains stable. This will reduce the tilt angle of the mobile phone, making it easier for the user to view and use.

[0015] (3) By setting the edge protrusion, the mobile phone can be stably attached to the inside of the mobile phone case body, and the protection effect of the corners of the mobile phone can be improved. At the same time, by setting the lens protrusion, the protection effect of the mobile phone lens can be improved.

[0016] (4) By setting a limiting component, the two moving rods are pushed by the spring to be firmly inserted into the slot, so as to limit and fix the moving strip, thereby fixing the position of the support seat and the extension seat. The distance between the support seat and the extension seat can be adjusted by simply moving the two moving rods close to each other until they are dislodged from the slot. After the adjustment is completed, the moving rods can be re-inserted into the close slot. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a mobile phone case with an adjustable support structure, including a mobile phone case body 1, an edge protrusion 2 formed on the inner edge of the front end of the mobile phone case body 1, the edge protrusion 2 can not only stably fasten the mobile phone to the inside of the mobile phone case body 1, but also improve the protection effect of the corners of the mobile phone, and a lens protrusion 3 formed on the outer edge of the mobile phone lens at the rear end of the mobile phone case body 1, which is used to improve the protection effect of the mobile phone lens.

[0026] The rear end of the main body 1 of the mobile phone case has an annular mounting groove 4, and a rotating seat 5 is rotatably mounted on the inner side of the mounting groove 4. The outer wall of the rotating seat 5 is formed with a limiting protrusion, and the inner wall of the mounting groove 4 has a limiting slide groove that matches it, so as to ensure the stability of the rotating seat 5 when it is rotatably mounted on the main body 1 of the mobile phone case. The top end face of the rotating seat 5 is rotatably connected to the support seat 7 through the damping shaft 6, and an extension seat 8 is provided below the support seat 7. The support seat 7 and the extension seat 8 form a complete annular structure.

[0027] In use, by rotating and pulling up the support base 7 and extension base 8 to form a certain angle with the rotating base 5, and then through the self-locking effect of friction generated by the damping rotating shaft 6, the main body of the phone case 1 and the phone can be stably supported at a certain angle. At the same time, by rotating the rotating base 5, different support effects for the main body of the phone case 1 and the phone can be achieved in the horizontal or vertical direction.

[0028] Movable strips 10 are fixedly connected to both ends of the extension base 8, and movable grooves 11 are provided inside both sides of the support base 7. The movable strips 10 slide on the inner side of the movable grooves 11. The ends of the movable strips 10 are formed with protrusions, and the movable grooves 11 are composed of two grooves that are adapted to the size of the movable strip 10 body and the protrusions, respectively. This allows the movable strips 10 to slide within a limited range along the movable grooves 11, thereby preventing the support base 7 from separating from the extension base 8. A connecting horizontal plate 13 is fixedly connected between the two ends of the support base 7, and a limiting component is provided on the inner side of the support base 7 and the connecting horizontal plate 13 to limit and fix the movable strips 10 and the movable grooves 11 relative to each other.

[0029] When in use, if the limited support distance causes the phone to tilt at an excessive angle (especially vertically), the extension seat 8 can be pulled away from the support seat 7 by the coordinated use of the moving bar 10, the moving groove 11, the connecting horizontal plate 13, and the limiting component. The moving bar 10 moves synchronously along the moving groove 11. When the overall support distance of the support seat 7 and the extension seat 8 is adjusted to be appropriate, the limiting component is used to fix the moving bar 10 and the moving groove 11 relatively, so that the adjusted length remains stable. This reduces the tilt angle of the phone case body 1 and the phone, making it easier for the user to view and use the phone.

[0030] Example 2: Based on Example 1, the extension base 8 has a pull opening at the bottom center, which allows the user to easily pull up the extension base 8 and the support base 7 by hooking the pull opening with their fingers for support. Anti-slip pads 9 are fixedly adhered to the bottom walls on both sides of the pull opening of the extension base 8. The anti-slip pads 9 can increase the friction between the extension base 8 and the mobile phone placement surface to improve the stability of the support.

[0031] Meanwhile, the limiting component includes multiple slots 12 opened on the side of the two moving bars 10 that are close to each other, and the slots 12 are vertically and evenly distributed. Two moving rods 14 that are symmetrically distributed are slidably connected to the inner side of the connecting horizontal plate 13. One end of each of the two moving rods 14 is inserted into one of the slots 12 on both sides. A spring 16 is fixedly connected between the two moving rods 14. By pushing the two moving rods 14 away from each other by the spring 16, the two moving rods 14 can be firmly inserted into the inner side of the slot 12, thereby limiting and fixing the moving bars 10, so as to fix the position of the support seat 7 and the extension seat 8. The distance between the support seat 7 and the extension seat 8 can be adjusted by simply moving the two moving rods 14 closer together and letting their ends disengage from the slots 12. After the adjustment is completed, the moving rods 14 can be re-inserted into the inner side of the corresponding close slots 12.

[0032] Furthermore, each of the two movable levers 14 has a toggle part 15 formed on the side of the two movable levers 14 that are close to each other, and the toggle part 15 protrudes from the end face of the connecting horizontal plate 13 so as to push the two movable levers 14 closer together by the toggle part 15.
