[0002] As living standards improve, people often engage in outdoor activities such as swimming and visiting water parks. During these activities, electronic devices such as mobile phones, tablets, and e-readers may be damaged by water, which is why waterproof protective cases have appeared on the market.

[0003] Existing waterproof protective cases mainly consist of a housing and a transparent soft film. Electronic devices are installed inside the housing, and the transparent soft film is installed on the housing to enclose and seal the electronic devices, thus providing waterproofing. The transparent soft film also corresponds to the screen of the electronic device, allowing users to press the transparent soft film to touch and use the electronic device.

[0004] However, existing waterproof protective cases often suffer from touch interruptions due to the inability of the transparent soft film to fully and tightly adhere to the screen, resulting in a poor user experience. Furthermore, the transparent soft film is prone to aging or scratches due to material limitations, leading to a short lifespan. Therefore, it is necessary to design a new waterproof protective case for electronic devices to solve this problem. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application. The connection relationships shown in the accompanying drawings are only for clear description and do not limit the connection method.

[0031] See appendix Figure 1 - Appendix Figure 8A waterproof protective case for electronic devices includes a housing 1 and a faceplate 2. The housing 1 has an outwardly opening cavity 10 for housing an electronic device 4, and the edge of the housing 1 is provided with a first sealing connection part 11 around the opening of the cavity 10. A tempered glass film 3 with an adhesive surface 31 is installed on the faceplate 2, and the edge of the faceplate 2 is provided with a second sealing connection part 21 around the tempered glass film 3. The second sealing connection part 21 and the second sealing connection part 21 can cooperate with each other, and the adhesive surface 31 of the tempered glass film 3 can be used to adhere to the screen 41 of the electronic device 4.

[0032] Specifically, during assembly, first open the faceplate 2, place the electronic device 4 into the receiving cavity 10, then hold the faceplate 2 and align it with the housing 1 until the second sealing connection part 21 and the second sealing connection part 21 cooperate and connect with each other, so that the faceplate 2 can be installed and fixed on the housing 1. At the same time, the tempered glass film 3 also tightly adheres to the screen 41 of the electronic device 4, thereby sealing the opening of the receiving cavity 10 and completely enclosing the electronic device 4. When in use, it is necessary to ensure that it is in an underwater environment. The user can touch the surface of the tempered glass film 3 with their finger to touch the screen 41 and thus control the electronic device 4.

[0033] In summary, this utility model achieves a sealed and waterproof connection between the housing 1 and the frame 2 through the cooperation of the first sealing connection part 11 and the second sealing connection part 21, as well as the cooperation of the tempered glass film 3 and the screen 41 of the electronic device 4; the screen 41 is fully and tightly adsorbed by the adhesive surface 31 of the tempered glass film 3 to avoid touch interruption during use, thus improving the user experience. At the same time, the tempered glass film 3 is not easy to age or get scratched, thus extending its service life.

[0034] It should be noted that electronic device 4 can be a mobile phone, tablet computer, e-reader, or other similar products. Due to the variety of types, this utility model does not impose any restrictions on this.

[0035] See appendix Figure 6 - Appendix Figure 8 The inner side of the face frame 2 is provided with a retaining strip 22, which is designed in a ring shape. The edge of the tempered glass film 3 is glued to the ring retaining strip 22 so that the tempered glass film 3 is embedded in the face frame 2. This design can not only improve the tightness of the installation of the tempered glass film 3 and prevent water leakage at the joint gap, but also make the tempered glass film 3 and the face frame 2 more integrated and improve the aesthetics.

[0036] It should be noted that, in addition to the above-mentioned installation method, the tempered glass screen protector 3 can also be fixed to the face frame 2 by means of snap-fit, and a rubber ring (not shown in the figure) can be set at the connection between the tempered glass screen protector 3 and the face frame 2 to achieve a seal. Since there are various installation methods, this utility model does not limit this.

[0037] See appendix Figure 7A peelable film 32 is covered on the adhesive side 31 of the tempered glass screen protector 3. The design of the film 32 can protect the adhesive side 31 of the tempered glass screen protector 3. During assembly, the film 32 is peeled off to expose the adhesive side 31 so that the screen 41 can be attached.

[0038] See appendix Figure 1 - Appendix Figure 7 The first sealing connection part 11 is provided with a sealing groove 111 and a buckle 112, and the second sealing connection part 21 is provided with a sealing strip 211 and a locking position 212. Both the sealing groove 111 and the sealing strip 211 are annular. When the sealing strip 211 is inserted into the sealing groove 111 and the buckle 112 engages with the locking position 212, the face frame 2 is installed on the housing 1, and the adhesive surface 31 of the tempered film 3 is tightly bonded to the screen 41 of the electronic device 4.

[0039] Specifically, during the process of aligning the face frame 2 with and bringing it closer to the housing 1, the sealing strip 211 is gradually inserted into the sealing groove 111, and the buckle 112 gradually engages with the locking position 212; after the sealing strip 211 is fully inserted into the sealing groove 111, the edges of the housing 1 and the face frame 2 are sealed, thus providing a single-layer waterproof function, and the buckle 112 is fully engaged with the locking position 212 to fix the face frame 2 to the housing 1; and the tempered glass film 3 is also simultaneously bonded to the screen 41 of the electronic device 4 through the adhesive surface 31.

[0040] See appendix Figure 1 - Appendix Figure 7 The buckle 112 is annular and formed next to the sealing groove 111, and the locking position 212 is annular and formed next to the sealing strip 211. The buckle 112 and the locking position 212 cooperate with each other to engage.

[0041] Specifically, after the sealing strip 211 is gradually and completely inserted into the sealing groove 111, the buckle 112 fully engages with the locking position 212 to fix the face frame 2 onto the housing 1 and to provide a double layer of waterproofing between the edges of the housing 1 and the face frame 2. Therefore, when the sealing strip 211, the sealing groove 111, the buckle 112 and the locking position 212 are all in a ring design, there is a double layer of sealing between the housing 1 and the face frame 2, which further improves the waterproofing performance.

[0042] See appendix Figure 3 - Appendix Figure 7 The buckle 112 has a first inclined surface 1120 at its top, and the face frame 2 has a second inclined surface 2120 at its bottom side next to the locking position 212. When the face frame 2 is close to the housing 1, the second inclined surface 2120 is in contact with and presses against the first inclined surface 1120 to drive the buckle 112 to deform and enter the locking position 212. This design improves the ease of installation between the face frame 2 and the housing 1.

[0043] See appendix Figure 5 - Appendix Figure 8The first sealing connection part 11 is provided with a protruding end 110, and the second sealing connection part 21 is provided with a recessed end 210. The protruding end 110 corresponds to the recessed end 210 to drive the tempered film 3 to align with the screen 41 of the electronic device 4.

[0044] Specifically, during the process of aligning the faceplate 2 with the housing 1, the protruding end 110 of the first sealing connection 11 can be first aligned and inserted into the recessed end 210 of the second sealing connection 21 for preliminary alignment. Then, the faceplate 2 is moved along the height direction of the protruding end 110 until the faceplate 2 comes close to and abuts against the housing 1. Therefore, the combined use of the protruding end 110 and the recessed end 210 can ensure that the steel film can be more accurately aligned with the screen 41 of the electronic device 4, and can also make the faceplate move stably and come close to the housing 1, avoiding the problem of the adhesive surface 31 shifting, and effectively reducing the air bubbles generated after the adhesive surface 31 is bonded to the screen 41.

[0045] See appendix Figure 2 - Appendix Figure 6 A magnetic ring 12 is installed on the back of the housing 1. The magnetic ring 12 corresponds to the magnetic coil (not shown in the figure) of the electronic device 4 and the external wireless charger (not shown in the figure). The user attaches the wireless charger to the magnetic ring 12, and the electronic device 4 can be charged through the magnetic coil. There are many kinds of electronic devices 4 with magnetic coils, such as common mobile phones and e-readers. Magnetic charging is also an existing technology, so it will not be further described in this utility model.

[0046] See appendix Figure 3 - Appendix Figure 7 A waterproof button 13 is installed on the side wall of the housing 1, and the waterproof button 13 corresponds to the control key 42 of the electronic device 4. The user can control the electronic device 4 by pressing the waterproof button 13 to activate the control key, which is convenient for underwater shooting operations. The structure of the waterproof button 13 is relatively conventional in the field of waterproof housings and belongs to the prior art. Therefore, its structure will not be described in detail in this utility model.

[0047] It should also be noted that, although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application.
