The third thermal insulation and sunshade canopy 3 has second sliding blocks 7 fixedly connected to both sides of its inner wall. The bottom of the first thermal insulation and sunshade canopy 1, the second thermal insulation and sunshade canopy 2, and the third thermal insulation and sunshade canopy 3 all have base plates 8 fixedly connected to both sides of their bottom ends. Each base plate 8 has four movable wheels 9 arranged in a linear array fixedly connected to its bottom end. The base plates 8 at the bottom of the sunshade canopy, with four movable wheels 9 arranged in a linear array fixed on the base plates 8, allow the entire sunshade canopy to be easily moved and... The first, second, and third insulated sunshades 1, 2, and 3 each include insulation panels 10, which are used to maintain the temperature inside the shed. The sunshade cloth 11 can block direct sunlight and reduce the temperature rise inside the cold storage. The outer walls of the three insulation panels 10 are all fixedly connected to the sunshade cloth 11, and the outer walls of the three sunshade cloths 11 are all fixedly connected to the reflector 12. The reflector 12 can reflect sunlight away, further reducing heat absorption and improving the sunshade effect of the shed.

Each layer of the shed includes insulation panels 10, sunshade cloth 11, and reflector 12, which blocks the intrusion of external heat and ultraviolet rays and improves the insulation performance of the cold storage.

[0032] Please see Figure 2 , Figure 4 andFigure 5 A grating transmitter 13 is fixedly connected to one side of the inner wall of the first insulated sunshade 1, and a grating receiver 14 is fixedly connected to the side of the inner wall of the first insulated sunshade 1 away from the grating transmitter 13. The grating transmitter 13 and the grating receiver 14 correspond to each other. The grating transmitter 13 emits light beams, which are received by the grating receiver 14. When an object or person enters the area between the grating transmitter 13 and the grating receiver 14, the light beams are blocked, causing the grating receiver 14 to be unable to receive a complete light signal, thus triggering the corresponding warning device to light up and prompting the truck driver to stop in time. The outer walls of the first insulated sunshade 1 are also fixedly connected to... The first heat-insulating sunshade shed 1 is fixed to two sides of a fixed block 15. Each fixed block 15 has a third sliding groove 16 on one side. A bidirectional screw 17 is rotatably connected inside each of the two third sliding grooves 16. A first movable block 18 is threaded to both ends of the outer wall of each of the two bidirectional screw 17. Two motors 19 are fixedly connected to the upper ends of each fixed block 15. The output ends of each motor 19 pass through one end of the fixed block 15 and are fixedly connected to the bidirectional screw 17 via a coupling. The fixed blocks 15 are fixed to both sides of the outer wall of the first heat-insulating sunshade shed 1, serving as a support and connection base. The third sliding groove 16 is located on one side of the fixed block 15 to accommodate and guide the bidirectional screw 17 and the first movable block 18. The movement of the 8-axis is achieved by rotating the bidirectional screw 17 inside the third slide groove 16, and threading it to the first moving block 18 through the thread on its outer wall. When the bidirectional screw 17 rotates, the first moving block 18 moves simultaneously along the thread direction of the screw. Fixed plates 21 are fixedly connected to both sides of the third heat-insulating sunshade 3. Each of the two fixed plates 21 has a fourth slide groove 22 inside, and a second moving block 23 is slidably disposed inside each of the two fourth slide grooves 22. As the main sunshade and heat-insulating structure, the third heat-insulating sunshade 3 needs to be able to adjust its position according to actual needs. The fixed plates 21 are fixedly connected to both sides of the third heat-insulating sunshade 3. As a support and connection, it is opened inside the fixed plate 21 to accommodate and guide the movement of the second moving block 23. The design of the slide groove allows the moving block to slide smoothly inside it. The four first moving blocks 18 and the second moving blocks 23 are rotatably connected to each other in pairs by scissor frames 20. The first moving blocks 18 and the second moving blocks 23 serve as the connection points of the scissor frames 20, providing a basis for support and adjustment. The scissor frame 20 is a hinged structure made of two intersecting metal rods or similar materials. When the first moving block 18 moves, the scissor frame 20 will unfold or fold accordingly, thereby changing its length and angle.

[0033] Please see Figure 1 , Figure 2 and Figure 3Indicator lights 24 are fixedly connected to the surfaces of both fixed plates 21, and warning lights 25 are fixedly connected to one side of the upper end of both fixed plates 21. These lights are fixedly connected to the surface of the fixed plates 21 and located in a conspicuous position within the truck driver's line of sight, used to indicate to the truck driver that the vehicle has been parked correctly. The warning lights 25 emit an audible and visual warning when the sunshade moves, alerting nearby personnel to avoid the area. The second insulated sunshade 2 is slidably installed inside the first insulated sunshade 1, and the third insulated sunshade 3 is slidably installed inside the second insulated sunshade 2. Two first sliders 5 are slidably installed inside the first slide groove 4, and two second sliders 7 are slidably installed inside the second slide groove 6. The first slide groove 4 is located at an appropriate position on the first insulated sunshade 1 to guide the sliding of the first sliders 5. The first sliders 5 are fixedly connected to the sides or appropriate positions of the second insulated sunshade 2. By sliding inside the first slide groove 4, the second slider 5 moves. The second insulated sunshade 2 slides inside the first insulated sunshade 1. The second sliding groove 6 is opened at an appropriate position in the second insulated sunshade 2 to guide the sliding of the second slider 7. The second slider 7 is fixedly connected to both sides or an appropriate position of the third insulated sunshade 3. By sliding inside the second sliding groove 6, the third insulated sunshade 3 can slide inside the second insulated sunshade 2. All three insulation boards 10 are made of high-density polyurethane foam, and all three reflectors 12 are made of aluminum. High-density polyurethane foam has excellent thermal insulation performance and can effectively block the transfer of external heat. As the main insulation layer of the insulated sunshade, the high-density polyurethane foam insulation board 10 can significantly improve the insulation effect of the sunshade and reduce energy consumption. Aluminum has good reflectivity and thermal conductivity. It can reflect most of the sunlight and heat, reducing the temperature rise inside the sunshade.

[0034] In this embodiment, by setting up a first heat-insulating sunshade shed 1, a second heat-insulating sunshade shed 2, and a third heat-insulating sunshade shed 3, a heat-insulating and sun-shading structure is formed. Each layer of the sunshade shed includes an insulation board 10, a sunshade cloth 11, and a reflector 12, which blocks the intrusion of external heat and ultraviolet rays, improving the heat insulation performance of the cold storage. The bottom of the sunshade shed is provided with a base plate 8, on which four movable wheels 9 arranged in a linear array are fixed, so that the entire sunshade shed can be easily moved and positioned, and the position of the sunshade shed can be adjusted to adapt to different sun-shading and heat-insulating needs. The insulation board 10 is used to maintain the temperature inside the shed, the sunshade cloth 11 can block direct sunlight and reduce the temperature rise inside the cold storage, and the reflector 12 can reflect sunlight out, further reducing heat absorption and improving the sun-shading effect of the sunshade shed. This sunshade shed achieves the advantages of heat insulation and sun shading through multi-layer heat-insulating and sun-shading design, efficient sun-shading and reflection, etc.

[0035] The working principle of the above embodiments is as follows:

[0036] First, the sunshade is installed at the entrance and exit of the cold storage. The first insulated sunshade 1, the second insulated sunshade 2, and the third insulated sunshade 3 are nested sequentially and connected by sliders and grooves. The bottom plates 8 of all three are equipped with casters 9 for easy movement and positioning. Each layer of the sunshade includes a high-density polyurethane foam insulation board 10, a sunshade cloth 11, and a reflector 12 made of aluminum, collectively forming an insulated sunshade structure. When it is necessary to extend the sunshade to increase shading and insulation effects... Two motors 19 drive two bidirectional screws 17 to rotate, which in turn drives the first moving blocks 18 to move relative to each other. The movement of the two first moving blocks 18 causes the scissor bracket 20 to extend and retract, which in turn moves the third sunshade. The third sunshade is moved by the sliding of the second slider 7 in the second slide groove 6, which in turn moves the second sunshade, thus realizing the unfolding action. When the truck enters the sunshade, after the rear of the truck reaches the position, it blocks the light beam emitted by the grating emitter 13. When the grating receiver 14 does not receive the light signal, the indicator light 24 lights up to indicate to the driver that the truck has stopped in place and can stop.
