Technical Field
[0001] This utility model belongs to the field of mobile phone accessories technology, specifically relating to a mobile phone interface protection device with charging fixing function. Background Technology
[0002] Smartphones are a general term for mobile phones that have an independent operating system and independent running space, allowing users to install programs provided by third-party service providers such as games and navigation apps, and can access wireless networks through mobile communication networks. With the rapid development of technology, smartphones have become an indispensable part of people's lives. From daily communication and social entertainment to work, study, and mobile payments, the functions of smartphones are becoming increasingly powerful, and their usage frequency has also increased significantly. As a key link in maintaining the normal operation of smartphones, their importance is self-evident.
[0003] However, in actual use, the problem of chargers easily detaching during phone charging frequently occurs. In a home environment, when people use their phones to charge in bed or on the sofa, physical movement or unintentional pulling can easily cause the charger to fall off the phone's charging port. For example, if you're using your phone in bed at night and want to put it aside to charge when you get tired, you might accidentally bump into the charging cable while turning over, causing the charger to separate from the phone and interrupting charging. The next morning, your phone will be low on battery, affecting normal use. In an office setting, employees may accidentally bump into the charging cable while charging their phones during work breaks due to the many items on their desks, or a colleague might accidentally bump into it while moving around, causing the charger to detach. This not only... Interrupting the charging process can also cause wear and tear on the phone's charging port due to repeated plugging and unplugging of the charger. In public places such as restaurants and cafes, it is common for people to charge their phones while eating. In such situations, the surrounding environment is complex and people are moving around frequently, making it easy for collisions or pulling of the charging cable to occur, causing the charger to fall off. Moreover, in some public charging facilities, due to the use by many people, the charging cable interface may be damaged to varying degrees, further increasing the risk of the charger falling off. Although there are some phone cases on the market, most of these cases only focus on protecting the appearance of the phone and preventing it from being impacted and scratched, but lack an effective solution to the problem of the charger easily falling off during charging.

[0011] Preferably, the protrusion fits tightly to the socket, the shape and size of the protrusion are adapted to the socket, and the fixing area, flipping area and connecting strip are integrally formed.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] (1) The device of this utility model forms a reliable fixing mechanism by the cooperation between the flip area of the silicone sheet and the protrusion on the charger. When charging, the flip area is flipped to the appropriate position and the socket is put on the outside of the protrusion on the charger, which can firmly fix the charger to the charging port of the mobile phone. This fixing method can effectively resist various accidental pulling and collisions, and avoid the problem of the charger falling off due to user activities, collisions with surrounding objects, etc. The fixing effect of this device can reduce the shaking and loosening between the charger and the charging port of the mobile phone, reduce the current fluctuation caused by poor contact, and the stable transmission of current can not only improve the charging speed, but also reduce the damage to the mobile phone battery and extend the battery life.
[0014] (2) The design of this utility model fully considers different types and specifications of mobile phone cases and can be adapted to various mobile phones that can wear mobile phone cases. Whether it is a hard mobile phone case, a soft mobile phone case or a mobile phone case with a special design, the fixed function can be achieved by pasting the silicone sheet on the back of the mobile phone case near the charging port. This wide compatibility allows users to use this device without changing the mobile phone case, which greatly improves the convenience and universality of use. The protrusions on the charger can be fixed to the charger by pasting, without being limited by the brand and model of the charger. Whether it is the original charger or the third-party charger, as long as its shape and size meet certain requirements, the protrusions of this device can be installed to achieve the cooperation with the silicone sheet.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0022] Example 1:
[0023] Please see Figure 1 - Figure 5 As shown, a mobile phone interface protection device with charging fixing function includes:
[0024] Phone case 1, with a charging slot 11 on one side and a charger 12 on the other side;
[0025] Silicone sheet 2 is disposed on one side of phone case 1. Silicone sheet 2 includes a fixing area 21, a flipping area 22, and a connecting strip 23. A protrusion 24 is fixedly connected to one side of the fixing area 21. A socket 25 is opened on one side of the flipping area 22. The socket 25 is correspondingly set with the protrusion 24. A protrusion 24 is also provided on one side of the charger 12.
[0026] Specifically, the fixing area 21 is attached to the back of the phone case 1 near the charging slot 11, the socket 25 is fitted on the outside of the protrusion 24, the fixing area 21 and the flip area 22 are connected by the connecting strip 23, so that the flip area 22 can be flipped on the side of the fixing area 21, the protrusion 24 and the socket 25 are tightly fitted, the protrusion 24 and the socket 25 are matched in shape and size, and the fixing area 21, the flip area 22 and the connecting strip 23 are integrally formed.
[0027] As can be seen from the above, both the phone case 1 and the charger 12 are user-owned accessories. The fixing area 21 is attached to the back of the phone case 1 near the charging slot 11 with 3M adhesive. The flip area 22 can be flexibly flipped on one side of the fixing area 21 and can be fastened to one side of the fixing area 21 by the cooperation of the protrusion 24 and the socket 25. The protrusion 24 on the charger 12 can also be attached to the charger 12 with 3M adhesive. Users can attach it themselves according to the actual size of the end of the charger 12.
[0028] In use, first, put the phone case 1 on the phone normally. Peel off the 3M adhesive protective film on the back of the fixing area 21. Accurately align the fixing area 21 with the position on the back of the phone case 1 near the charging slot 11. Gently press the silicone sheet 2 to firmly stick it to the phone case 1. Attach the other independent protrusion 24 to one side of the charger 12. When attaching, ensure that the position of the protrusion 24 does not affect the normal use of the charger 12 and matches the position of the socket 25 on the subsequent flip area 22. Next, insert the charger 12 into the phone's charging port. Then, align the socket 25 on the flip area 22 with the protrusion 24 on one side of the charger 12. Slowly fold the flip area 22 so that the socket 25 fits smoothly onto the outside of the protrusion 24. During the insertion process, ensure that the socket 25 and the protrusion 24 fit tightly without gaps. To ensure a secure fit, gently pull the charging cable to check if the charger 12 is firmly fixed to the phone's charging port. If the charger 12 is stably fixed to the phone, the fixation is successful and normal charging can proceed. If the charger 12 shows signs of looseness, the insertion position of the socket 25 and the protrusion 24 needs to be readjusted to ensure a secure fit. After charging is complete, hold the flip area 22 of the silicone sheet 2 and flip it upwards, gradually bringing the flip area 22 closer to the back of the phone case 1. Align the socket 25 on the flip area 22 with the protrusion 24 on the fixing area 21, and slowly press the flip area 22 downwards so that the socket 25 fits onto the protrusion 24 of the fixing area 21. At this point, the flip area 22 is stored behind the phone case 1 and will not affect the daily carrying and use of the phone.
