When the trunk needs to be protected from cold, the handle 64 is turned so that the handle 64 drives the screw rod 61 to rotate, so that the screw rod 61 drives the dovetail The slider 9 slides, so that the dovetail slider 9 drives the telescopic frame 5 to expand, so that the telescopic frame 5 drives the movable plate 4 to move upward, so that the movable plate 4 drives the arc-shaped shell 15 to move upward through the fixed rod 3, so that the arc-shaped shell 15 drives The cold-proof layer 13 is unfolded, and at the same time, through the engagement of the positioning block 10 and the positioning groove 11, the arc-shaped plate 1 on the other side is deployed upwards synchronously, and then the rotation of the handle 64 is stopped, so that the cold-proof layer 13 can be protected around the trunk. , when in a high temperature environment, the endothermic box 88 is made to absorb heat, so that the gas inside the endothermic box 88 is heated and expanded, so that the sealing plug 86 drives the spring 87 to deform, so that the sealing plug 86 drives the rack 85 to move, so that the rack 85 Drive the gear 815 to rotate, so that the gear 815 drives the knob switch 84 to close the controller 83, so that the controller 83 can control the blower fan 810 and the heating plate 814 to stop running. The type of the knob switch 84 can be a micro switch, which can make the gear 815 Slight rotation can trigger the action of the knob switch 84. The structure of the heating box 88 is composed of cylinders with different sizes and diameters, wherein the small cylinder is provided with a rack 85, and the large cylinder and the small cylinder are filled with volume The gas with a relatively large expansion coefficient, of course, is not ruled out as a gas-liquid two-phase substance. With such a design, by arranging the rack 85 in the small cylinder, both the large cylinder and the small cylinder at the rear can be filled with gas, which leads to The change in gas volume caused by the overall volume can be focused in a small cylinder to make the rack produce a longer stroke. The essence of the small cylinder is an amplifier, which produces a change in the stroke caused by the change in the total volume expansion and improves the micro motion. The sensitivity of the switch. If it is in a low temperature environment, the elastic force of the spring 87 drives the sealing plug 86 to reset, so that the sealing plug 86 drives the rack 85 to reset, so that the rack 85 drives the gear 815 and the knob switch 84 to rotate, so that the controller 83 controls the blower fan 810 and The heating plate 814 runs, so that the fan 810 enters the air through the air inlet 813, so that the air can be heated through the heating plate 814, and the hot air is input into the arc-shaped shell 15, and the connecting pipe 12 is connected with the arc-shaped shell 15, so that Hot air can enter multiple arc-shaped shells 15 and be sprayed out through the air outlet head 14, thereby protecting the trunk. The two ends of the sealing plug 86 can be provided with limit protrusions (not shown in the figure) to prevent the large driving force caused by the large ambient temperature difference from adversely affecting the knob switch 84, or even malfunctioning. In addition, if ventilation is required , turn the handle 64 in the opposite direction, so that the handle 64 drives the screw rod 61 to rotate, so that the second nut 62 drives the dovetail slider 9 to slide, so that the dovetail slider 9 drives the telescopic frame 5 to shrink, so that the telescopic frame 5 passes through the movable plate 4 and the fixed rod 3 drive the arc-shaped shell 15 to fold downwards, so that the cold-proof layer 13 can carry out the work of folding, and now the trunk can be ventilated.

This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.
