[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and with reference to data. It should be understood that the embodiments are only intended to illustrate the present invention and are not intended to limit the scope of the present invention in any way.

[0036] The mobile terminal in this application refers to mobile terminal devices such as mobile phones and tablets.

[0037] The airbag bracket in the present application refers to a bracket with a retractable airbag that is directly attached to the back of a mobile terminal or to a protective shell of the mobile terminal, and props up the mobile device on the surface of an object when the airbag is extended.

[0038] like Figure 1-2 As shown, the utility model discloses an airbag bracket for a mobile terminal, including an airbag component and a base 3;

[0039] The airbag assembly comprises an airbag 1 and a fixing ring 2 connected by secondary injection molding; the airbag 1 is made of TPU, and the fixing ring 2 is made of PC.

[0040] The airbag 1 includes a telescopic end 11 and a connecting end 12 . The telescopic end 11 can move axially as the airbag 1 is telescoped. The connecting end 12 is fixedly connected to the fixing ring 2 .

[0041] The base 3 has a fixing groove 31; the fixing ring 2 and the fixing groove 31 are detachably connected. The base 3 has a front and a back, the front is used to connect with the airbag 1, and the back is attached to the mobile terminal (not shown in the figure). In this embodiment, the fixing ring 2 and the fixing groove 31 are detachably connected by threaded connection. In this embodiment, the fixing ring 2 has an internal thread, and the fixing groove 31 has an external thread. In one embodiment, the fixing ring 2 has an external thread, and the fixing groove 31 has an internal thread.

[0042] The telescopic end 11 is rotatably connected to a support 4 , which is a disc-shaped structure. The outer diameter of the support 4 is larger than the inner diameter of the fixing ring 2 . When the airbag 1 contracts, the support can cover the opening of the fixing ring 2 .

[0043] like Figure 2-4 As shown, the fixed ring 2 includes a fixed outer ring 21 and a connecting inner ring 22 connected to each other, and the fixed outer ring 21 can be detachably connected to the base 3; the connecting inner ring 22 is connected to the connecting end 12 of the airbag. The connecting inner ring 22 includes a connecting inner ring body and ribs 221 evenly distributed along the outer periphery of the connecting inner ring, the ribs 221 are connected to the fixed outer ring 21, and an axially through channel 222 is formed between the ribs 221. The connecting end 12 of the airbag 1 can cover the connecting inner ring 22. By arranging the ribs 221 at intervals on the outer periphery of the connecting inner ring body, on the one hand, it is used to connect the fixed outer ring 21 and the connecting inner ring body, and on the other hand, the channel 222 formed between the ribs 221 forms an injection channel during secondary injection molding, and the injection channel enables the connecting end of the airbag to cover the connecting inner ring 22 during secondary injection molding.

[0044] In one embodiment, the connecting end 12 of the airbag is configured to pass through the channel 222 and form a stop step (not shown in the figure) at the lower opening of the channel 222, and the stop step can limit the connecting end 12 of the airbag from detaching from the connecting inner ring 22.

[0045] like Figure 5-7 As shown, in another embodiment, the connecting end 12 of the airbag further has a lower edge 121, a limiting ring 311 is coaxially arranged in the fixing groove 31, the outer side surface of the limiting ring 311 is configured to be able to abut against the inner side surface of the lower edge 121, the inner side surface of the fixing groove 31 is configured to be able to abut against the outer side surface of the lower edge 121, and the inner edge of the fixing outer ring 21 has a flange 211 protruding downward, and the flange 211 can abut against the outer side surface of the lower edge 121 in a vertical direction. The advantage of this arrangement is that by further locking the lower edge 121 of the airbag, during the use of the airbag bracket, especially during the stretching of the airbag, the connection ability between the airbag and the base 3 is further strengthened, and a part of the connection strength between the airbag and the connecting inner ring 22 is assumed.

[0046] like Figure 8-10 As shown, in one embodiment, the base 3 has an attachment mechanism, which is used to attach the airbag bracket to the back of the mobile terminal or the protective shell of the mobile terminal, and the attachment mechanism includes a clamping attachment mechanism 32, a magnetic adsorption attachment mechanism 33 or an adhesive attachment mechanism 34.

[0047] like Figure 8 As shown, a clamping and attaching mechanism 32 is provided on the back of the base 3, and the clamping and attaching mechanism 32 includes a clamping mechanism body 321, and clamping blocks 322 inserted at both ends of the clamping mechanism body 321, and an elastic element (not shown in the figure) is also connected between the clamping block 322 and the clamping mechanism body 321, and the elastic element is used to prevent the clamping block 322 from moving to both ends, thereby providing a clamping force for the clamping and attaching mechanism 32, so that the airbag bracket can be clamped and connected to mobile devices of different sizes.

[0048] like Fig.11 As shown, in one embodiment, retractable hanging holes 35 are provided on both sides of the base 3, and the hanging holes 35 are used to connect with the hanging chain 36. The retractable hanging holes are provided on both sides of the base 3, so that the airbag bracket can cooperate with the chain, so as to be used as a mobile phone chain to carry the mobile phone. That is, when the airbag bracket of the present application is used as a mobile phone bracket, the airbag is pulled out and used as a bracket or a mobile phone ring. When the mobile phone needs to be carried at any time, it is connected to the chain through the hanging holes on both sides, so as to be used as a mobile phone chain.
