Embodiment 1

[0028] like Figure 1-7 As shown, the present invention provides a multi-functional backpack mat, including a base plate 1 installed on the back of the backpack and an elastic pad 2 installed on the back of the base plate 1. There are two elastic pads 2, which are symmetrically arranged on the base plate 1 Above, a fan device 3 is provided between the elastic pads 2, a rechargeable mobile power supply 5 is provided at the bottom of the front of the substrate 1, a solar cell panel 4 is installed on the upper side of the substrate 1, and the solar cell panel 4 The power transmission line is electrically connected to the charging interface of the mobile power supply 5, and the power transmission interface of the mobile power supply 5 is connected to the fan device 3 through a DC-AC inverter point; the fan device 3 includes a bracket and is installed on the The protective shell 31 on the bracket and the fan installed in the protective shell 31, the side of the protective shell 31 ...

Embodiment 2

[0039] like Figure 8 As shown, the difference between this embodiment and Embodiment 1 lies in two points: 1. The number, arrangement and additional structure of the elastic pads 2; 2. The number of fans. The elastic pad 2 also includes elastic pads 2 respectively arranged on the upper and lower sides of the back of the substrate 1, and the elastic airbags 22 in the elastic pads 2 on the upper and lower sides pass through the elastic airbags 22 on the left and right sides of the back of the substrate 1. The WeChat air pump is connected to the valve, and the air pump and the valve are respectively connected in series to the power transmission interface of the mobile power supply 5 through corresponding switches. And there are two fans arranged up and down in the middle of the base plate 1 .

[0040] The elastic airbags 22 on the left and right sides can be sucked into the elastic airbags 22 on the upper and lower sides through the air pump and the valve, so that if the user f...

Abstract

The invention discloses a multifunctional backpack cushion, and the cushion comprises a substrate and elastic cushions. The number of elastic cushions is two, and the two elastic cushions are disposedon the substrate in a manner of left-right symmetry. A fan device is also disposed between the elastic cushions, and the bottom of the front of the substrate is provided with rechargeable mobile power supply. The upper side of the substrate is provided with a solar cell panel, and a power output line of the solar cell panel is electrically connected to a charging interface of the mobile power supply. A power output interface of the mobile power supply is connected to the fan device through a DC-AC inverter point. The fan device comprises a support, a protection housing installed on the support, and a fan installed in the protection housing. One side, facing the substrate, of the protection housing is an air inlet, and the other side is an air outlet. The air outlet is fixedly provided with a protection fence, and the back surface of the substrate is covered by silica gel. The fan is installed at the central part through a support, and the incoming of air from the upper and lower sidesis convenient. The wind is strong, so the backrest is easier to be dry, thereby enabling a user to feel comfortable.

Description

technical field [0001] The invention relates to the field of backpacks, in particular to a multifunctional backpack pad. Background technique [0002] Nowadays, with the improvement of people's living standards, the number of people who go out to travel every year has risen sharply. However, there are always inconveniences when going out, which causes a lot of troubles for everyone. For example, the long-term contact between the long-carrying travel bag and the back causes the back to be completely sweaty, and the long-term carrying of the backpack puts a lot of pressure on the shoulders, which is very uncomfortable. In addition, although the backpack can pack more and heavier items, once the user falls into the water, the shoulder straps and abdominal straps are not easy to open, which is very dangerous for the user. Therefore need to improve existing knapsack structure, adapt to the multiple situations that go out to run into. [0003] For example, the utility model pate...
