Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone cases, and more particularly to an inflatable airbag mobile phone case that is drop-proof and impact-proof. Background Technology
[0002] Most mobile phone cases currently available are made of plastic. During use, people frequently encounter bumps, knocks, or accidental drops that break the phone. Especially in winter when temperatures are low, the plastic casing becomes brittle and harder, making it more prone to breakage upon impact, significantly impacting the phone's lifespan.
[0003] To address this, existing phone cases incorporate airbags within the casing to prevent damage. However, these airbags are typically located at the four corners, and are inflated during manufacturing to create pressure. This design makes manufacturing cumbersome, and installing the phone is difficult due to the airbag's pressure causing it to bulge. Improper handling can even damage the airbag, rendering it useless. Furthermore, when the phone is dropped face down, the large aspect ratio can cause the unprotected center of the screen to collide directly with bumps or ledges on the ground, resulting in more severe damage, as the center is the most vulnerable part of the screen. Utility Model Content
[0004] The purpose of this invention is to provide an inflatable airbag-type mobile phone case that overcomes the shortcomings of the prior art. Using an inflatable airbag effectively avoids installation difficulties; the distribution of several small inflatable airbags can buffer or eliminate impact forces from all directions, thus protecting the mobile phone; the inflatable airbag design is also relatively simple to manufacture.
[0005] This utility model provides a novel inflatable airbag-type phone case, characterized by comprising an outer protective layer and an inner protective layer, both of which have pre-drilled connection holes for connecting to external devices on the phone; both the outer and inner protective layers are made of malleable material; the inner periphery and inner edge of the inner protective layer are fused with the outer periphery and outer edge of the outer protective layer to form fused edges, thereby forming a closed airbag between the outer and inner protective layers; a through hole is provided on the outer surface of the outer protective layer, and an air nozzle and an air valve are provided in the through hole, which communicate with the cavity of the closed airbag.
[0006] In the aforementioned inflatable airbag-type phone case, the outer protective layer and the inner protective layer are fused together to form multiple rib fusion edges. The rib fusion edges divide the sealed airbag into several small airbags, and each small airbag is connected to an air nozzle and an air valve through an air tube.
[0007] In the aforementioned inflatable airbag-type phone case, the air tube is fixed inside the welded edge of the rib.
[0008] The aforementioned inflatable airbag-type mobile phone case has a cavity on the outer surface of the outer protective layer, the air nozzle and air valve are located in the cavity, and a cap is provided at the opening of the cavity.
[0009] The aforementioned inflatable airbag-type phone case has a plastic cover with a snap-on mechanism.
[0010] The beneficial effects of this utility model are: 1. The inflatable airbag is relatively simple to manufacture and has low production costs. 2. Because it uses an inflatable airbag, it can be inflated after the phone is installed, making it easier to install the phone. 3. The distribution of several small inflatable airbags can better buffer or eliminate impact forces from all directions, preventing damage to the phone due to drops or bumps, thus providing all-round protection for the phone.

[0020] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.
[0021] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The illustration shows an embodiment of an inflatable airbag-type mobile phone case according to this utility model. It includes an inner protective layer 1 and an outer protective layer 2. Both the outer protective layer 2 and the inner protective layer 1 have pre-drilled connection holes and buttons required for connecting external devices to the mobile phone, such as a camera / video hole 23, a charging interface 24, an audio hole 25, and buttons 26. The outer protective layer 2 and the inner protective layer 1 are made of malleable materials such as TPU, PVC, or silicone. The inner periphery 11 and inner edge 12 of the inner protective layer 1 are fused with the outer periphery 21 and outer edge 22 of the outer protective layer 2 to form an edge fusion edge B12, thereby forming a closed airbag N12 between the outer protective layer 2 and the inner protective layer 1. The inner perimeter 11 and outer perimeter 21 mentioned here refer to the outermost peripheral edges of the inner protective layer 1 and the outermost peripheral edges of the outer protective layer 2, respectively. The inner edge 12 and outer edge 22 refer to the perimeters of the connecting holes and buttons located in the inner protective layer 1 and the outer protective layer 2, such as the perimeter of the camera hole 23. A through hole is provided on the outer surface of the outer protective layer 2, and an air nozzle 3 and an air valve are provided in the through hole. The air nozzle 3 and the air valve are connected to the cavity of the sealed airbag N12. Thus, before inflating the phone case, the phone is placed inside it. At this point, the phone's edges and back are pressed against the inner protective layer. Then, the air valve and nozzle 3 inflate the sealed airbag N12 to a certain pressure, causing it to bulge. This creates cavities around the edges and back of the phone, allowing the N12 to cushion or absorb impacts from all directions when the phone is bumped or dropped, providing all-around protection. If the pressure inside the cavities decreases during use, it can be re-inflated to maintain a certain pressure.
[0022] In a further embodiment, a receiving cavity 27 is provided on the outer surface of the outer protective layer 2, and the air nozzle 3 and the air valve are disposed within the receiving cavity 27. A cap 28 is provided at the opening of the receiving cavity 27. This can better protect the air nozzle 3 and the air valve, preventing damage that could cause the sealed airbag N12 to leak.
[0023] Reference Figure 6 , Figure 7 , Figure 8 , Figure 9 The image shows a second embodiment of an inflatable airbag-type mobile phone case according to this utility model. The difference between this second embodiment and the first embodiment is that the sealed airbag N12 is composed of multiple small airbags. See... Figure 6 As shown, on the corresponding areas on the back of the phone, small airbags N121 (upper left), N122 (upper right), N123 (lower left), and N124 (lower right) are formed by horizontal rib welded edges B121 and vertical rib welded edges B122. See... Figure 8 As shown, around the perimeter of the phone, the first edge rib welded edge B123, the second edge rib welded edge B124, and the third edge rib welded edge B125 form the first edge small airbag N125, the second edge small airbag N126, and the third edge small airbag N127. In this embodiment, the number of small airbags is set according to the size of the phone case and actual needs. Each small airbag is independent and connected to an air nozzle via an air tube, such as... Figure 8 In this configuration, the upper right small airbag N122 is connected to the air distribution tube 5 via the upper right air tube 41, and the air distribution tube 5 is connected to the air nozzle 3. The lower right small airbag N124 is connected to the air distribution tube 5 via the lower right air tube 42. The first edge small airbag N125 is connected to the air distribution tube 5 via the lower edge air tube 43. In this configuration, each small airbag has an air tube connected to the air distribution tube 5, and all are supplied with air via the air nozzle 3 and an air valve. All air tubes and air distribution tubes 5 are placed between the inner protective layer 1 and the outer protective layer 2, as shown below. Figure 7 The middle edge air tube 44; the branch air tube 5 can be integrally formed with the outer protective layer 2, and each air tube can be preset and fixed within the rib welded edge. Using small airbags, the failure of one small airbag will not affect the normal use of the other small airbags. Furthermore, due to the presence of the horizontal rib welded edge B121 and the vertical rib welded edge B122, a channel is created on the back of the phone between the two small airbags, such as... Figure 7 As shown, a channel D121 is generated between the upper left small airbag N121 and the upper right small airbag N122, and a channel D122 is generated between the second small airbag N126 on the edge and the upper left small airbag N121. These channels can help dissipate heat from the phone and are more conducive to protecting the phone.
