The emergence of automatic medicine delivery vehicles can effectively solve problems such as low efficiency and high labor costs in medicine delivery, and can also reduce problems such as mismatch and loss of medicines caused by human factors.

[0003] Existing automatic medicine delivery vehicles are generally composed of an automatic conveying vehicle body and a box body placed on the automatic conveying vehicle body. During transportation, some medicines need to be kept warm due to their medicinal properties to prevent the medicines from becoming ineffective. Such medicines, such as vaccines, biological products, etc., in order to meet the insulation requirement, existing automatic medicine delivery vehicles may also have an insulation function. Such medicine delivery vehicles generally install insulation cotton in the box where the medicines are placed or make the box body into a vacuum insulation structure, and the insulation effect is achieved by the insulation cotton or the vacuum that blocks heat transfer. Since there is a certain space in the box, when the medicines that need to be kept warm are placed in the box, at this time, the temperature in the box will generally be higher than the temperature when the medicines are just placed in. Therefore, after the medicines are placed in the box, the temperature of the medicines will rise to a certain extent, which affects the efficacy of the product to a certain extent.

[0004] Therefore, it is necessary to provide a new automatic sterile medicine delivery vehicle to solve the above technical problems. Utility Model Content

A box body 2 for placing medicines is installed on the top of the automatic conveying vehicle body 1. A vacuum insulation chamber 3 and a refrigeration chamber 4 separated from each other are respectively opened at positions near the outer surface and the inner wall of the box body 2. A refrigeration device is arranged in the refrigeration chamber 4. The refrigeration device can move in the vertical direction under the action of a lifting device installed in the refrigeration chamber 4. The sealed box cover is arranged on the top of the box body 2. The refrigeration device includes a mounting frame 5, two first refrigeration components 7 and two second refrigeration components 8 that are arranged opposite to each other. The first refrigeration component 7 and the second refrigeration component 8 can both be semiconductor refrigerators. The mounting frame 5 moves in the vertical direction under the action of the lifting device. The frame 5 is arranged along the refrigeration cavity 4, and the four corners of the inner side of the installation frame 5 are fixedly installed with installation blocks 6. The first refrigeration component 7 is installed on the two pairs of installation blocks 6 in the horizontal direction, and the second refrigeration component 8 is installed on the two pairs of installation blocks 6 in the longitudinal direction. Through the refrigeration device, the temperature in the inner cavity of the box body 2 is first reduced by the refrigeration component, and the installation frame 5 is driven to reciprocate in the vertical direction by the lifting device, thereby driving the refrigeration component to reciprocate, so that the temperature of the inner cavity of the box body 2 can be uniformly reduced. When the temperature of the inner cavity of the box body 2 is reduced to a certain degree, the medicine is placed in the inner cavity of the box body 2, so that the temperature of the medicine is not easy to spread too much, and the purpose of heat preservation is achieved through the vacuum insulation cavity 3;

[0026] The lifting device includes a threaded rod 10, a guide rod 11 and two connecting blocks 9. The two connecting blocks 9 are fixedly connected to the two sides of the installation frame 5 respectively. The bottom end of the threaded rod 10 is movably connected to the inner wall of the refrigeration chamber 4. The top of the threaded rod 10 extends to the outside of the refrigeration chamber 4. The threaded rod 10 is threadedly connected to one of the connecting blocks 9. The guide rod 11 is fixedly connected to the inner wall of the refrigeration chamber 4. The guide rod 11 is movably inserted into the through hole opened in the other connecting block 9. A motor 12 is installed on the top of the box body 2, and the output end of the motor 12 is fixedly connected to the top of the threaded rod 10.

[0027] The sealed box cover includes a cover plate 13, a fixing frame 14 and a flexible sealing pad 15. The fixing frame 14 is fixedly installed at the bottom of the cover plate 13. The bottom end of the fixing frame 14 is an inclined surface. The flexible sealing pad 15 is arranged around the fixing frame 14. The flexible sealing pad 15 fits the inner wall of the box body 2. The flexible sealing pad 15 can be rubber.

[0028] Two clamping assemblies for clamping medicines are installed in the box body 2, and the clamping assemblies include a fixed plate 16, a U-shaped mobile frame 17 and a spring 18.

The two ends of the spring 18 are respectively fixedly connected to the side wall of the fixed plate 16 and the inner wall of the mobile frame 17. Baffles 19 are provided at both ends of the mobile frame 17. When the mobile frame 17 is pulled, the spring 18 is compressed, and the medicine is placed in the box body 2. Under the action of the spring 18, the medicine is clamped by the mobile frames 17 on both sides, so that the medicine is not easy to shake during transportation.

[0029] The working principle provided by the utility model is as follows: when the device is used, before putting the medicine in, the temperature in the inner cavity of the box body 2 is first lowered by the refrigeration component, and the threaded rod 10 is driven to rotate by the motor 12. Under the action of the threaded rod 10, the mounting frame 5 performs reciprocating motion in the vertical direction, thereby driving the refrigeration component to perform reciprocating motion, so that the temperature of the inner cavity of the box body 2 can be uniformly lowered. When the temperature of the inner cavity of the box body 2 is reduced to a certain degree, the movable frame 17 can be pulled, and the spring 18 is compressed to place the medicine in the box body 2. Under the action of the spring 18, the medicine is clamped by the movable frames 17 on both sides, and the cover plate 13 is placed on the top of the box body 2. The flexible sealing pad 15 is moved into the inner cavity of the box body 2 after being compressed to a certain extent, thereby having a certain sealing effect on the box body 2, making the medicine not easily contaminated by bacteria, and achieving the purpose of insulation through the vacuum insulation chamber 3.
