[0027] Referring to Figures 1 to 8As shown in the specific embodiment, the technical scheme adopted by the present embodiment is: a breathable and heat-dissipating type double-shoulder backpack, comprising a backpack body 1, two shoulder straps 2 arranged at the right end of the backpack body 1, and a plurality of support plates 3 arranged at the right end face of the backpack body 1, wherein the plurality of support plates 3 are longitudinally equidistantly arranged at the right end face of the backpack body 1, the left end of the support plate 3 is arranged obliquely upward from bottom to top, the right end of the support plate 3 is arranged obliquely downward from top to bottom, the right end face of the support plate 3 is provided with a flexible contact layer 4, a plurality of air holes 5 are arranged on the right end of the support plate 3 and the flexible contact layer 4, and the left end and the right end of the support plate 3 are in an inverted V shape or an inverted L shape. When the support plate 3 is directly arranged at the right end of the backpack body 1, the support plate 3 is arranged on the backpack body 1 by means of adhesives or hot melt adhesives. The number of support plates 3 can also be two, and the two support plates 3 are arranged on the upper and lower sides of the backpack body 1. The support plate 3 is integrally formed and can be produced by mold manufacturing or 3D printing.

[0028] The included angle between the left end of the support plate 3 and the right end face of the backpack body 1 is 33°-38°, and the included angle between the right end of the support plate 3 and the right end face of the backpack body 1 is 10°-12°.

[0029] The flexible contact layer 4 is a silica gel layer or a memory cotton layer or a sponge layer. The flexible contact layer 4 can reduce the extrusion force of the support plate 3 on the back of the human body when the support plate 3 is in contact with the back of the human body, thereby improving the comfort.

[0030] A connecting seat 6 is arranged between the right end of the backpack body 1 and the left end of the support plate 3, the left end of the connecting seat 6 is fixedly arranged at the right end of the backpack body 1, and the left end of the support plate 3 is connected to the right end of the connecting seat 6 through a connecting piece. The left end of the connecting seat 6 is fixedly connected to the right end of the backpack body 1 by adhesives.

[0031] The connecting piece comprises a sub-connecting plate 7 arranged at the left end of the support plate 3, a connecting horizontal plate 8 arranged at the left upper end of the sub-connecting plate 7, a longitudinal clamping groove 9 arranged at the upper end of the connecting seat 6 and below the connecting horizontal plate 8, a positioning clamping plate 10 arranged at the lower end of the connecting horizontal plate 8 and in gap cooperation with the longitudinal clamping groove 9, and a connecting bolt 11 arranged between the middle part of the sub-connecting plate 7 and the connecting seat 6. There are two support plates 3 on the sub-connecting plate 7, and the two support plates 3 are arranged in front of and behind each other. The connecting bolt 11 is located between the two support plates 3. The connecting bolt 11 is threadedly connected with the sub-connecting plate 7 and the connecting seat 6, or the screw rod part is threadedly connected with the connecting seat 6, and the sub-connecting seat 6 is provided with a plug hole larger than the diameter of the screw rod part of the connecting bolt 11 and smaller than the diameter of the head part of the connecting bolt 11, and the sub-connecting plate 7 is pressed tightly on the connecting seat 6 through the head part of the connecting bolt 11.

[0032] The right end surface of the support plate 3 is provided with an arc-shaped contact surface 12. When the arc-shaped contact surface 12 is not provided, the support plate 3 is provided in a whole horizontal state. The flexible contact layer 4 is also arc-shaped.

[0033] The support plate 3 is a polycarbonate plate, a polystyrene plate, a polyoxymethylene plate, a nylon plate or a carbon fiber plate.
