Embodiment 1

[0029] Such as Figure 1-7 As shown, the present invention provides a lifesaving backpack pad, comprising a base plate 1 mounted on the back of the backpack and an elastic pad 2 mounted on the back of the base plate 1. There are two elastic pads 2 symmetrically arranged on the left and right On the substrate 1, 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 The power transmission line of the board 4 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, an installation The protective case 31 on the support and the fan installed in the protective case 31, the side of the protective case 31 facin...

Embodiment 2

[0040] Such as 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 .

[0041] 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 use...

Abstract

The invention discloses a backpack pad with a lifesaving function. The backpack pad comprises a base plate and two elastic pad bodies; the two elastic pad bodies are symmetrically arranged on the baseplate left and right, and a fan device is arranged between the elastic pad bodies; a rechargeable mobile power source is arranged at the bottom of the front surface of the base plate, a solar panel is mounted at the upper side of the base plate, a power transmission line of the solar panel is electrically connected to a charging interface of the mobile power source, and a power transmission interface of the mobile power source is connected to the fan device through a DC-AC inverter point; the fan device comprises a bracket, a protection shell mounted on the bracket and a fan mounted in the protection shell, an air outlet opening of the fan device is fixedly provided with a protection grille, and the back surface of the base plate is covered with silica gel; each elastic pad body comprisesa silica gel layer located on the surface and an elastic airbag arranged inside. According to the backpack pad, the fan is mounted in the middle through the bracket, air inlet is convenient from theupper and lower sides or the left and right sides, the wind power is large, the back is more likely to be dry, and a user feels comfortable.

Description

technical field [0001] The invention relates to the field of backpacks, in particular to a backpack pad with lifesaving function. 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 m...
