[0030] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0031] According to one embodiment of the utility model, Figure 1 and Figure 2 As shown, an airbag mobile phone case comprises:

[0032] A housing, wherein the housing forms a receiving cavity;

[0033] An inner frame 2, the inner frame 2 is arranged in the outer shell, the middle areas of the four sides of the inner frame 2 are provided with embedded convex strips, and the outer shell is provided with openings adapted to the embedded convex strips;

[0034] The inner frame 2 is sealed and connected to the outer shell, and the outer sides of the four corners of the inner shell and the inner sides of the four corners of the outer shell form a closed airbag cavity.

[0035] As a common mobile phone accessory, mobile phone cases are mainly used to protect mobile phones, especially the four corners of mobile phones. According to research, in the mobile phone drop test experiment, the risk of damage when the mobile phone falls on the front or back is much smaller than the risk of damage when the mobile phone falls diagonally. This is because the mobile phone itself is rectangular. Although the corners are rounded, there is still a problem of stress concentration. Therefore, the impact of diagonal drops on the mobile phone is the greatest. In addition, after the mobile phone falls diagonally, it will usually bounce and cause secondary damage to the mobile phone.

[0036] To solve this problem, the inventor of the utility model proposes an airbag mobile phone case, which includes an outer shell and an inner frame 2, wherein the outer sides of the four corners of the inner shell and the inner sides of the four corners of the outer shell form a closed airbag cavity. The airbag cavity is formed at the four corners of the mobile phone case to protect the mobile phone, thereby buffering the impact force borne by the mobile phone when it falls diagonally, and giving the mobile phone case the ability to resist impact.

[0037] Furthermore, in this embodiment, the airbag cavity is filled with a certain amount of gas, which may be air, nitrogen or other single or mixed gases, and the outer shell and inner frame 2 of the mobile phone are both made of rubber material with a certain elasticity. When the mobile phone falls diagonally, the airbag corresponding to the contact angle with the ground is squeezed, and the impact force is dispersed to the outer shell and inner frame 2. The outer shell and inner frame 2 of the mobile phone absorb the impact force through their own elastic deformation, which can effectively prevent damage to the mobile phone.

[0038] In this embodiment, the shell includes a back plate 1 and an outer frame 3 arranged around the back plate 1, and the opening is provided with four sides of the outer frame 3. The back plate 1 and the outer frame 3 together constitute the shell. To further improve the integrity of the airbag mobile phone case, in this embodiment, the back plate 1 is placed in a shell mold and then the outer frame 3 is formed by injection molding. The advantage of this method is that it can ensure that the back plate 1 and the outer frame 3 form an integrated component, and then the inner frame 2 is sealed and connected to the shell. The connection point can be located at the edge of the outer frame 3 or on the back plate 1; this setting method provides a larger fault tolerance and operation space for subsequent steps.

[0039] According to an embodiment of the utility model, the back plate 1 includes a back plate 1 body and a lens frame 4, the back plate 1 body is provided with a lens hole, and the lens frame 4 is detachably connected to the back plate 1 body outside the lens hole. In this embodiment, the back plate 1 and the lens frame 4 are arranged in a split and detachable manner, on the one hand, because the mobile phone case has a certain aesthetic effect in addition to protecting the mobile phone, in this way, the user can match the lens frame 4 according to the color of his preference, which enhances the fun and playability of the mobile phone case.

[0040] Further, such as Figure 1 and Figure 2 As shown, the embedded ridges include a first ridge 5, a second ridge 6, a third ridge 7 and a fourth ridge 8 which are arranged in sequence around the four sides of the inner frame 2, wherein the second ridge 6 and the fourth ridge 8 are combined with the long sides of the outer shell, the first ridge 5 and the third ridge 7 are combined with the short sides of the outer shell, and the third ridge 7 is provided with a charging port opening 9 and a speaker opening 10. The embedded ridges are formed in the middle area of ​​the four sides of the inner frame 2 of the airbag mobile phone case of the utility model, and the embedded ridges are matched with the openings on the outer frame 3, so that before the inner frame 2 and the outer shell are sealed and connected, the relative positions of the inner frame 2 and the outer shell can be relatively fixed, and the positions of the two can be fixed without the help of external positioning tools, so as to prepare for the subsequent sealing connection steps.

[0041] In the present embodiment, the inner frame 2 and the outer shell are sealed and connected by ultrasonic welding. Since the inner frame 2 is provided with an embedded convex strip and the outer shell is provided with a corresponding opening, the outer shell and the inner frame 2 can be assembled and positioned before ultrasonic welding, avoiding the need for additional multiple clamps to fix the outer shell and the inner frame 2 separately during ultrasonic welding, thereby saving production costs for the production of the airbag mobile phone case of the utility model.

[0042] In this embodiment, the embedded ridges include a first ridge 5, a second ridge 6, a third ridge 7 and a fourth ridge 8 which are arranged in sequence around the four sides of the inner frame 2. The above four ridges correspond to the four sides of the mobile phone respectively, among which the third ridge 7 corresponds to the side where the charging port and the speaker hole of the mobile phone are located, so the charging port opening 9 and the speaker opening 10 are set on the third ridge 7.

[0043] Furthermore, a volume key cover 11 is provided on the second convex strip 6 or the fourth convex strip 8; a power key cover 12 is provided on the second convex strip 6 or the fourth convex strip 8. The volume key and / or the power key can be selectively provided on the second convex strip 6 or the fourth convex strip 8 according to the corresponding mobile phone model.

[0044] According to an embodiment of the utility model, the embedded convex strips on the inner frame 2 are in the same plane as the side surface of the outer shell after being embedded in the outer shell, and the surface of the embedded convex strips is formed with anti-slip grooves. During use, the user's hand usually holds the mobile phone along the length direction of the mobile phone. In order to ensure the hand feel of the mobile phone case, the embedded convex strips on the inner frame 2 are in the same plane as the side surface of the outer shell after being embedded in the outer shell, which avoids the side frame of the airbag mobile phone from having local protrusions or local depressions that affect the hand feel. In addition, if Figure 1 and Figure 2 As shown, in this embodiment, anti-skid patterns are formed on the surface of the embedded convex strips to increase the friction between the user's hand and the airbag mobile phone case, and the anti-skid patterns also have the effect of further improving the hand feel.

[0045] In this embodiment, the embedded convex strips on the inner frame 2 are made of thermoplastic polyurethane elastomer material, i.e., TPU material. This material has good wear resistance and can support the long-term use of the airbag mobile phone case. More importantly, this material has good ductility. When the mobile phone falls diagonally, the airbag can transfer the impact to the inner frame 2 and the outer shell after bearing the impact. The inner frame 2 and the outer shell can absorb the impact force through their own elastic deformation.

[0046] In the description of the specification, the description with reference to the terms "one embodiment", "some embodiments", "an embodiment", "some embodiments", "an example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
