When pushing the first mobile pallet 8 and the second mobile pallet 9, the surface of the positioning rod 11 will be plugged into the inner wall of the positioning hole 10, so as to enhance the stability of the first mobile pallet 8 and the second mobile pallet 9.

[0035] Example 2

[0036] The difference between the present embodiment 2 and the embodiment 1 is that: a slide groove 20 is provided on the top of the base 7, and a slide plate 21 adapted to the slide groove 20 is fixedly installed on the bottom of the first movable tray 8 and the second movable tray 9, and the surface of the slide plate 21 is slidably connected to the inner wall of the slide groove 20, and the top of the base 7 is slidably connected to the limit plate 22, and the top of the limit plate 22 is threadedly connected to the limit rod 23, and the bottom of the limit rod 23 penetrates the limit plate 22 and extends to the bottom of the limit plate 22 and is threadedly connected to the surface of the base 7, and screw holes 24 adapted to the limit rod 23 are equidistantly provided on the surface of the base 7, and the surface of the limit rod 23 is threadedly connected to the inner wall of the screw hole 24, and the front and rear sides of the inner cavity of the carriage body 3 are fixedly installed with temperature and humidity sensors 25, and protective covers 26 are fixedly installed on the front and rear sides of the inner cavity of the carriage body 3 and outside the temperature and humidity sensors 25;

[0037] By using the slide groove 20 and the slide plate 21 in coordination, the stability of the first movable tray 8 and the second movable tray 9 during movement can be improved, and the positions of the first movable tray 8 and the second movable tray 9 can be prevented from being offset during the movement. By using the limit plate 22 and the limit rod 23 in coordination, when loading is completed, the user can push the limit plate 22 to make the limit plate 22 fit with the surface of the second movable tray 9, and then tighten the limit rod 23 to fix the positions of the first movable tray 8 and the second movable tray 9. In this embodiment, two movable trays are provided, and the size and number of the movable trays can be changed during actual use. By setting the temperature and humidity sensor 25, the temperature and humidity inside the carriage body 3 can be monitored. The temperature and humidity sensor 25 is connected to the signal of the refrigeration unit 15, and the refrigeration power of the refrigeration unit 15 can be adjusted according to the temperature and humidity inside the carriage body 3. By setting the protective cover 26, the temperature and humidity sensor 25 can be protected.

[0038] The surface of the shell 12 and the surface of the carriage body 3 are both set in an arc shape, and the front and rear sides of the carriage body 3 are both inclined. The surface of the carriage body 3 and the inner wall of the bucket 2 are fixedly connected together through an L-shaped connecting plate 27, and the L-shaped connecting plate 27 is fixedly installed with the surface of the carriage body 3 and the inner wall of the bucket 2 by countersunk screws. A high-mounted brake light 28 is fixedly installed on one side of the carriage body 3 and above the door 4, and an arc-shaped shoulder 29 is fixedly installed on one side of the carriage body 3 and on both sides of the high-mounted brake light 28. A taillight maintenance hole 1 is opened on one side of the carriage body 3 and on both sides of the door 4;

[0039] The surface of the shell 12 and the surface of the car body 3 are both set to be arc-shaped, so that the car body 3 as a whole is streamlined to a certain extent, which greatly reduces the air resistance of the whole vehicle during driving. The front and rear sides of the car body 3 are inclined at a certain angle, forming a perfect transition with the appearance of the pickup truck bed 2, as if it were one body. The surface of the car body 3 and the inner wall of the bed 2 are fixedly connected together by an L-shaped connecting plate 27, which can perfectly match the pickup truck bed 2; the lower edges of the L-shaped connecting plates 27 on the front and rear sides are sealed with sealant at the contact edges with the bed 2 to ensure beauty while preventing water leakage, and red and white warning labels are affixed. There are downward arc-shaped shoulders 29 on both sides from the position of the high-mounted brake light 28, which has the effect of protruding the high-mounted brake light 28 and being beautiful. Through the taillight maintenance hole 1, the taillight maintenance operation is convenient.

[0040] Example 3

[0041] The difference between the present embodiment 3 and the embodiments 1 and 2 is that: the curvature of one side of the carriage body 3 and the place where the front of the vehicle 1 is close to each other is consistent with the curvature of the cab outer shape of the front of the vehicle 1, so that the carriage body 3 fits the cab of the front of the vehicle 1 as much as possible, and reduces the gap between the carriage body 3 and the cab of the front of the vehicle 1, so as to maximize the inner length of the carriage body 3, and is connected with the front end of the pickup truck's truck bed 2, which well ensures the consistency of the appearance of the whole vehicle, and is beautiful and generous; the front and rear surfaces of the carriage body 3 are fixedly installed with window-shaped lines, which improves the beauty of the whole vehicle; four shallow grooves are left in the middle of the top of the carriage body 3, and three reinforcing ribs are formed in the middle of the grooves to reinforce the carriage body 3;

[0042] After the carriage body 3 and the truck bed 2 are installed, polyurethane foam is sprayed between the carriage body 3 and the inner wall of the truck bed 2, which can enhance the sealing performance and have good thermal insulation performance. The carriage body 3 uses polyurethane foam as the thermal insulation material and is made using the mature "sandwich board" manufacturing process. It has good thermal insulation performance and can be used with the refrigeration unit 15 to stably maintain the temperature in the compartment at the required lower temperature to meet the medical refrigeration needs. The compartment door 4 uses a rectangular steel tube frame as the door frame, which is firm and durable; the rear door frame is made of 2.5mm thick stainless steel plates bent and welded, and calcium plastic strips are installed around the door frame and between the panels, which can be used as an insulation bridge to reduce the heat exchange between the compartment and the rear door frame; the rear door panel also uses polyurethane material as the thermal insulation layer, and sealing strips are installed around the door panel to enhance the air tightness and thermal insulation performance of the compartment after the rear door is closed;

[0043] The inner wall of the carriage body 3 is made of 0.8mm thick brushed stainless steel inner skin, which is neat, beautiful and corrosion-resistant. Three air guide groove profiles are installed on one side and the front and rear sides of the inner cavity of the carriage body 3, and two air guide groove profiles are installed on the rear door panel. The floor adopts 5cm wall floor, which together form an air circulation channel in the carriage to keep the temperature around the goods consistent, meeting the requirements of pharmaceutical refrigerated trucks.
