As shown in Figure 21,22, in another embodiment of the present invention, the first side plate 11 has the auxiliary side plates 17 of an extension, and auxiliary side plates 17 is towards the first cushion chamber 41 bendings, and the bending place of the first side plate 11 is provided with and connects air chamber C61-C6y.
Wherein, the both ends of an intermediate coat 30 are fixed in the auxiliary side plates 17 two sides corresponding heat-sealing relative with the 5th side plate 15.
One lateral edges 32 of intermediate coat 30 seals a lateral edges 22 of the internal membrane 20 on fixing and the 5th side plate 15, the convergence part 17a of auxiliary side plates is fixed in opposite side edge 31 heat-sealings of intermediate coat 30, auxiliary side plates 17 has inflatable a plurality of air chamber C7y, the second side plate 12, the 3rd side plate 13 and the 4th side plate 14 form the second cushion chamber 42 and containing cavity 45 around forming the first cushion chamber 41, the first side plates 11, auxiliary side plates 17 and the 5th side plate 15 heat-sealings.When being implemented on curved surface TV when (figure does not show); not only containing cavity 45 and the second cushion chamber 42 can tune to best position; and auxiliary side plates 17 can be filled up curved surface TV because of the formed space of curvature, the first side plate 11 and auxiliary side plates 17 can increase the effect of buffer protection.For presenting relative position and the structure of the second cushion chamber 42 and containing cavity 45, Figure 21 and Figure 22 only show the second cushion chamber 42 and the middle stationary state having sealed of containing cavity 45, the bottom side of the second cushion chamber 42 presents the not open state of heat-sealing, be beneficial to indicate the position of the second cushion chamber 42, the bottom side that actual heat-sealing state is the second cushion chamber 42 has sealed fixing.Moreover the first side plate 11 further can be provided with a plurality of air chamber C61-C6y and a plurality of air guide channel C1 of being connected with in the middle of auxiliary side plates 17, to be communicated with a plurality of air chamber C11-C1y and a plurality of air chamber C7y.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
