Therefore, these storage compartments of delivery robots have specific functions. These storage compartments with specific functions inevitably have a complex and compact structure due to the increased electronic components and wiring harnesses, resulting in cumbersome wiring layouts and making disassembly and maintenance inconvenient.

Alternatively, when the interval distance is greater than a second preset distance, the control module controls the power module to turn off the power, and when the interval distance is less than a second preset distance, the control module controls the power module to turn on the power. The second preset distance is greater than the distance between the first bottom wall and the second bottom wall when the storage module is installed in the accommodating space.

[0009] In some embodiments of this application, the storage compartment structure further includes a locking mechanism, which is installed on one of the support frame and the compartment body. The locking mechanism includes a retractable latch, and the other of the support frame and the compartment body is provided with a lock hole.

[0013] In some embodiments of this application, the inner wall of the support frame is provided with a plurality of first guide portions, which are spaced apart, and the outer wall of the compartment is provided with a plurality of second guide portions, which are arranged in a one-to-one correspondence with the plurality of first guide portions.

[0014] In some embodiments of this application, the chamber includes a first storage chamber and a second storage chamber arranged side by side; a temperature control mechanism is located between the first storage chamber and the second storage chamber, the temperature control mechanism includes a cooling end and a heating end disposed opposite to the cooling end, the cooling end facing the first storage chamber to cool the first storage chamber, and the heating end facing the second storage chamber to heat the second storage chamber.

[0015] In some embodiments of this application, a first fluid channel is provided between the heating end and the second storage chamber.

[0018] The storage compartment structure provided in this application is used to store items on a delivery robot for delivery to its destination. This storage compartment structure is formed by combining independent support frames and storage modules. The storage modules are not only stably housed within the support frame's storage space, but can also be easily and quickly removed from the support frame's storage space. Furthermore, when the storage module is installed into the support frame's storage space, a first connector on the first bottom wall and a second connector on the second bottom wall directly plug into each other to form an electrical connection. When the storage module is removed from the support frame's storage space, the first and second connectors separate, breaking the electrical connection. The storage compartment structure of this application adopts a split design, allowing the storage modules used for storing items to be easily and quickly removed from the support frame's storage space. Moreover, the split design uses the first and second connectors to complete the electrical connection, eliminating complex wiring layouts.

[0042] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] According to a first aspect of this application, a storage compartment structure is provided. Furthermore, according to a second aspect of this application, the storage compartment structure provided in the embodiments of this application is applied to a delivery robot.

[0045] like Figures 1 to 13 As shown, the storage compartment structure provided in the embodiments of this application includes a support frame 10 and a storage module 20. As... Figure 2 and Figure 4 As shown, the support frame 10 has a receiving space 11, the receiving space 11 has a first bottom wall 12, and the first bottom wall 12 is provided with a first connector 13. The first connector 13 is used for electrical connection with a power module (wherein, the power module can be set on the support frame 10 or on the body of the delivery robot). Figures 1 to 6 The storage module 20 includes a compartment 21 and a temperature control mechanism. The compartment 21 has a second bottom wall 23, and the second bottom wall 23 is provided with a second connector 24. The temperature control mechanism is installed in the compartment 21 and can adjust the temperature inside the compartment 21. The temperature control mechanism is electrically connected to the second connector 24. The storage module 20 can slide into or out of the receiving space 11. When the storage module 20 is installed in place in the receiving space 11, the first bottom wall 12 is opposite to the second bottom wall 23, and the second connector 24 is plugged into the first connector 13 to form an electrical connection.

[0046] The storage compartment structure is formed by combining independent support frames 10 and storage modules 20. The storage modules 20 can not only be stably housed within the receiving space 11 of the support frame 10, but can also be easily and quickly removed from the receiving space 11. Furthermore, when the storage module 20 is installed into the receiving space 11 of the support frame 10, the first connector 13 on the first bottom wall 12 and the second connector 24 on the second bottom wall 23 can directly connect to form an electrical connection. When the storage module 20 is removed from the receiving space 11 of the support frame 10, the first connector 13 and the second connector 24 disconnect, breaking the electrical connection. The storage compartment structure of this application adopts a split design structure, which allows the storage module 20 for storing items to be easily and quickly disassembled and removed from the receiving space 11 of the support frame 10. Furthermore, the split design structure uses the first connector 13 and the second connector 24 to complete the electrical connection, eliminating the complex wiring layout. The wire harnesses are respectively hidden inside the support frame 10 and the storage module 20, making the overall external appearance of the storage compartment structure clean and simple.

[0047] like Figure 2 As shown, the storage compartment structure also includes a positioning sensor 25, which is mounted on the first bottom wall 12 or the second bottom wall 23. The positioning sensor 25 is used to detect the interval distance and send the interval distance to the control module. The interval distance is the distance between the first bottom wall 12 and the second bottom wall 23. The control module can be a remote control device in the user's hand; it can also be a control module in the delivery robot's control system used to match and control the storage compartment structure, i.e., the control module is set on the body of the delivery robot; or, alternatively, the control module can be set on the support frame 10.

[0048] When the interval distance is greater than a first preset distance, the control module controls the power module to cut off power; when the interval distance is equal to the first preset distance, the control module controls the power module to power on. The first preset distance is the distance between the first bottom wall 12 and the second bottom wall 23 when the storage module 20 is installed in the receiving space 11. Alternatively, when the interval distance is greater than a second preset distance, the control module controls the power module to cut off power; when the interval distance is less than a second preset distance, the control module controls the power module to power on. The second preset distance is greater than the distance between the first bottom wall 12 and the second bottom wall 23 when the storage module 20 is installed in the receiving space 11, i.e., the second preset distance is greater than the first preset distance. In other words, the power module can power on the storage module 20 at a time that is not limited to the moment the storage module 20 is installed in the receiving space 11; it can also power on the storage module 20 before it is installed, as long as the first connector 13 and the second connector 24 have already completed electrical connection.

[0049] The distance from the opening of the accommodating space 11 to the first bottom wall 12 of the accommodating space 11 is D1; ​​when the storage module 20 is installed into the accommodating space 11, the distance between the first bottom wall 12 and the second bottom wall 23 is D2, that is, the first preset distance is D2; and the second preset distance is D0, so D2 < D0 ≤ D1. In fact, the second preset distance can also be slightly greater than D1.

[0050] To prevent the storage module 20 from easily detaching from the receiving space 11, such as Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 10 As shown, the storage compartment structure also includes a locking mechanism 30, which is installed on either the support frame 10 or the compartment body 21. The locking mechanism 30 includes a retractable latch 31, and the other of the support frame 10 and the compartment body 21 is provided with a lock hole 261. The latch 31 can extend to insert into the lock hole 261. That is, the control module is also used to control the latch 31 to extend and insert into the lock hole 261 when the interval distance is equal to a first preset distance, thereby locking the storage module 20 in the receiving space 11 and preventing the storage module 20 from easily falling out of the receiving space 11; and to retract and disengage from the lock hole 261. That is, the control module is connected to the control interface signal, and the control module is also used to control the latch 31 to retract and disengage from the lock hole 261 according to the signal sent by the control interface, so that the storage module 20 can slide out of the receiving space 11 along the extension direction of the first guide 15. The control interface can be set on the support frame 10, or the control interface can also be set on the body of the delivery robot.

[0051] like Figure 2 , Figure 4 , Figure 6As shown, the inner sidewall of the support frame 10 is provided with at least one first guide portion 15, wherein the inner sidewall of the support frame 10 and the first bottom wall 12 enclose an accommodating space 11 with an opening; the outer sidewall of the compartment 21 is provided with at least one second guide portion 26, wherein the outer sidewall of the compartment 21, the second bottom wall 23, and the entrance side of the compartment 21 constitute the outer surface of the compartment 21, the second bottom wall 23 is opposite to the entrance side, and the outer sidewall is a continuous circumferential sidewall. The second guide portion 26 is adapted to the first guide portion 15, and the storage module 20 slides into or out of the accommodating space 11 along the extending direction of the first guide portion 15. When the storage module 20 is installed into the receiving space 11 of the support frame 10, simply align the first guide portion 15 with the second guide portion 26, and then slide the storage module 20 along the extending direction of the first guide portion 15 (i.e., slide the second guide portion 26 along the first guide portion 15) to slide the storage module 20 into the receiving space 11, thus quickly installing the storage module 20 onto the support frame 10. When it is necessary to remove the storage module 20 from the support frame 10, simply slide the storage module 20 out of the receiving space 11 along the extending direction of the first guide portion 15 to quickly remove the storage module 20.

[0052] Preferably, the first guide portion 15 is configured as a guide rail, and the second guide portion 26 is configured as a guide groove, with the guide rail and guide groove being mutually compatible. That is, the guide rail and guide groove cooperate to allow the storage module 20 to slide into or out of the receiving space 11 along the guide rail. To facilitate the removal of the storage module 20, the storage module 20 is provided with a handle 29.

[0053] like Figure 2 , Figure 4 As shown, the locking mechanism 30 is mounted on the support frame 10 and correspondingly disposed with respect to the first guide portion 15. The locking tongue 31 can extend out of the first guide portion 15 or retract into the first guide portion 15. Figure 2 , Figure 4 , Figure 6 As shown, the lock hole 261 is located in the second guide portion 26.

[0054] In the storage compartment structure provided in this embodiment, the inner wall of the support frame 10 is provided with a plurality of first guide portions 15, which are spaced apart. The outer wall of the compartment 21 is provided with a plurality of second guide portions 26, which are arranged in a one-to-one correspondence with the plurality of first guide portions 15. In this way, the support frame 10 and the storage module 20 are stably confined within the receiving space 11 of the support frame 10 through multiple sets of mutually cooperating first guide portions 15 and second guide portions 26, preventing the storage module 20 from shaking relative to the support frame 10 within the receiving space 11. That is, the storage module 20 can remain stable within the receiving space 11.

[0055] In the embodiments of this application, there are two first guide portions 15, which are respectively disposed on the inner walls of opposite sides of the accommodating space 11 and are arranged facing each other. There are also two second guide portions 26, which are respectively disposed on the outer walls of opposite sides of the storage module 20 and are arranged in a one-to-one correspondence with the two first guide portions 15.

[0056] like Figures 1 to 13 As shown, the storage unit 21 includes a first storage compartment 211 and a second storage compartment 212 arranged side by side. A temperature control mechanism is located between the first storage compartment 211 and the second storage compartment 212. The temperature control mechanism includes a cooling end 221 and a heating end 222 disposed opposite to the cooling end 221. The cooling end 221 faces the first storage compartment 211 to cool it, and the heating end 222 faces the second storage compartment 212 to heat it. The storage module 20 of this application can simultaneously meet at least two storage needs, such as refrigerated storage and heated storage.

[0057] like Figure 4 , Figure 8 , Figure 10 , Figure 12 and Figure 13 As shown, a first fluid channel 223 is provided between the heating end 222 and the second storage chamber 212. The storage module 20 also includes a fluid conveying device 27 and a second fluid channel 281. The fluid conveying device 27 is installed at the inlet end of the first fluid channel 223 or the support frame 10, and the fluid conveying device 27 is connected to the inlet end of the first fluid channel 223. The second fluid channel 281 surrounds at least a portion of the second storage chamber 212, and the inlet end of the second fluid channel 281 is connected to the outlet end of the first fluid channel 223. The support frame 10 is provided with a fluid outlet 16, and the outlet end of the second fluid channel 281 is connected to the fluid outlet 16. In the storage module 20 of this application embodiment, the first fluid channel 223 corresponds to the side facing the heating end 222 of the second storage compartment 212, and the second fluid channel 281 circumferentially surrounds the other three sides of the second storage compartment 212. Thus, the first fluid channel 223 and the second fluid channel 281 together circumferentially surround the second storage compartment 212 (i.e., surround the outer wall of the aforementioned compartment body 21), uniformly heating the second storage compartment 212 circumferentially. The heating end 222 transfers heat to the first fluid channel 223, and the fluid conveying device 27 delivers fluid to the first fluid channel 223, where the fluid absorbs heat. Then, the heated fluid flows along the first fluid channel 223 into the second fluid channel 281, and the fluid flows along the second fluid channel 281. In this way, the second storage compartment 212 is uniformly heated circumferentially by the fluids in the first fluid channel 223 and the second fluid channel 281, achieving the function of heating and storing items.

[0058] In the storage compartment structure of this application, the fluid delivery device 27 can be fixedly installed at the inlet end of the second fluid channel 281, or the fluid delivery device 27 can be fixedly installed on the support frame 10.

[0059] The temperature control mechanism includes a heat-conducting element 224, which is connected to the heating end 222 and located on the side of the heating end 222 facing the second storage chamber 212. The opposite sides of the heat-conducting element 224 are respectively attached to the walls of the heating end 222 and the second storage chamber 212. The heat-conducting element 224 is provided with a first fluid channel 223. That is, the heat generated by the heating end 222 is directly transferred to the heat-conducting element 224. On one hand, the heat-conducting element 224 absorbs a portion of the heat and transfers it to the second storage chamber 212 to directly heat it. On the other hand, the fluid conveying device 27 delivers fluid into the first fluid channel 223 and absorbs another portion of the heat from the heat-conducting element 224. The fluid, after absorbing heat, flows along the first fluid channel 223 into the second fluid channel 281, where it flows and heats the second storage chamber 212. In this way, the second storage chamber 212 is heated circumferentially, achieving the function of heating and storing items. The heat-conducting element 224 is preferably a copper plate, as copper's excellent thermal conductivity contributes to heat absorption efficiency. Furthermore, to improve the heat exchange efficiency between the fluid and the heat-conducting element 224 during fluid flow within the first fluid channel 223, the first fluid channel 223 of the heat-conducting element 224 is preferably configured as a harmonica tube.

[0060] The temperature control mechanism also includes a cooling element 225 and a heat insulation device 226. The cooling element 225 has a cooling end 221 and a heating end 222 on its two opposite sides. The cooling element 225 is installed on the heat insulation device 226, which surrounds the periphery of the cooling element 225 and is connected to the periphery of the cooling element 225. The heat insulation device 226 has a heat dissipation outlet 2261 that is connected to both the outlet end of the first fluid channel 223 and the outlet end of the second fluid channel 281. The support frame 10 has a first outlet 17 that is connected to the heat dissipation outlet 2261. The cooling and heating principle of the thermocouple 225 utilizes the Peltier effect of the semiconductor thermocouple. When current passes through the thermocouple, one side of the thermocouple 225 absorbs heat and does work (i.e., the cooling side), while the other side releases heat and does work (i.e., the heating side). After reaching a dynamic equilibrium, the current continues to flow, and the cooling side continues to produce a cooling effect while the heating side continues to produce a heating effect. The maximum temperature difference between the cooling side and the heating side can reach over 60°C. Preferably, the heat insulation device 226 and the periphery of the thermocouple 225 need to be sealed. This can be achieved by using a durable silicone gasket or by using durable structural adhesive to fill the assembly gap between the heat insulation device 226 and the periphery of the thermocouple 225 to achieve a good seal. No single method is specified here.

[0061] In some embodiments of this application, the temperature control mechanism may also adopt a refrigeration method similar to that of a refrigerator for refrigeration (i.e., compressor refrigeration) and heating (condenser heat dissipation). In this case, the compressor refrigeration components are concentrated as the refrigeration end 221, and the condenser heat dissipation components are concentrated as the heating end.

[0062] In some embodiments of this application, the storage module is not provided with a heat-conducting component 224. In this case, the first fluid channel 223 is a channel for fluid flow formed by the cooperation of the side wall of the second storage chamber 212 and the heat insulation device 226.

[0063] Furthermore, such as Figure 8 , Figures 10 to 13 As shown, the temperature control mechanism also includes a cooling conductor 227, which is connected to the cooling end 221 and located on the side of the cooling end 221 facing the first storage chamber 211. The opposite sides of the cooling conductor 227 are respectively attached to the walls of the cooling end 221 and the first storage chamber 211. The cooling conductor 227 transfers the cold energy generated by the cooling end 221 to the first storage chamber 211, thereby cooling the items stored in the first storage chamber 211 and achieving the cooling and storage function.

[0064] Furthermore, the heat insulation device 226 simultaneously covers both the heat-conducting component 224 and the cold-conducting component 227. In other words, the heat insulation device 226 acts as the outer layer of the temperature control mechanism, covering the other components. In this way, the heat insulation device 226 can prevent the leakage of heat absorbed by the heat-conducting component 224 and cold absorbed by the cold-conducting component 227, thereby improving the efficiency of heat transfer and cold transfer.

[0065] In some embodiments of this application, the fluid conveying device 27 includes an air supply device for supplying air to the inlet end of the first fluid channel 223. The air supply device, the first fluid channel 223, the second fluid channel 281, and the fluid outlet 16 are connected to form a flow path. In this embodiment, the airflow flowing in the first fluid channel 223 absorbs and transfers heat to the heat-conducting element 224, and then the airflow flows into the second fluid channel 281 to heat the second storage chamber 212.

[0066] Alternatively, in some other embodiments of this application, the fluid delivery device 27 of the storage module includes a liquid pump device for pumping liquid to the inlet end of the first fluid channel 223, wherein the liquid pump device, the first fluid channel 223, the second fluid channel 281, and the fluid outlet 16 are connected to form a flow path. In this embodiment, the liquid flowing in the first fluid channel 223 absorbs the heat transferred to the heat conductor 224, and then the flowing liquid flows into the second fluid channel 281 and heats the second storage tank 212.

[0067] like Figures 1 to 4 , Figures 6 to 8 , Figures 10 to 13 As shown, the storage module 20 also includes a first insulating shell 51 and a second insulating shell 52. The first insulating shell 51 covers the first storage compartment 211 and is tightly attached to the outer wall of the first storage compartment 211, thereby improving the refrigeration effect of the refrigerated items stored in the first storage compartment 211. The second insulating shell 52 covers the second storage compartment 212, improving the heat preservation effect of the heated items stored in the second storage compartment 212. Furthermore, the first insulating shell 51 prevents the leakage of cold air from the first storage compartment 211, and the second insulating shell 52 prevents the leakage of heat from the second storage compartment 212, which helps to reduce the overall operating power of the temperature control mechanism and reduce energy consumption. The second insulating shell 52 has a second outlet 521 that communicates with the outlet end of the second fluid channel 281, and the second outlet 521 is connected to the fluid outlet 16.

[0068] In some embodiments of this application, such as Figure 8 , Figures 10 to 13 As shown, the storage module 20 also includes a channel component 28, which is located between the second insulation shell 52 and the second storage compartment 212. The channel component 28 is in close contact with the outer wall of the second storage compartment 212, and the second insulation shell 52 is in close contact with the outer wall of the channel component 28. A second fluid channel 281 is disposed within the channel component 28.

[0069] In some other embodiments of this application, when the second thermal insulation shell 52 covers the second storage chamber 212, it does not adhere to the outer wall of the second storage chamber 212, but is spaced apart from the outer wall of the second storage chamber 212, thereby forming a second fluid channel 281.

[0070] like Figure 6 As shown, the storage module 20 is provided with a heat dissipation outlet 2261, which is opposite to the outlet end of the first fluid channel 223. The heat dissipation outlet 2261 is connected to both the first fluid channel 223 and the second fluid channel 281. Furthermore, as... Figure 5 , Figure 6 and Figure 10As shown, the storage module 20 also includes a first valve 41 and a second valve 42. The first valve 41 is located at the inlet end of the second fluid channel 281, and can open and close the second fluid channel 281. The second valve 42 is located at the heat dissipation outlet 2261, and can open and close the heat dissipation outlet 2261. When the first valve 41 is open and the second valve 42 is closed, the fluid conveyed by the fluid conveying device 27 can absorb heat in the first fluid channel 223 and continue to flow along the second fluid channel 281, so that the second storage chamber 212 is uniformly heated circumferentially by the fluid in the second fluid channel 281 and the first fluid channel 223. When the first valve 41 is closed and the second valve 42 is open, the fluid conveyed by the fluid conveying device 27 absorbs heat in the first fluid channel 223 and is immediately discharged to the external environment from the heat dissipation outlet 2261. That is, most of the heat transferred from the heating end 222 to the second storage chamber 212 is carried away by the fluid and discharged to the external environment, and the amount of heat that the heating end 222 can use to heat the second storage chamber 212 is greatly reduced. This allows for heating and temperature control of the second storage compartment 212. Preferably, both the first valve 41 and the second valve 42 are solenoid valves.

[0071] like Figures 1 to 4 , Figure 8 , Figures 11 to 13 As shown, the storage compartment structure also includes a temperature sensor 91. Specifically, the first storage compartment 211 has at least one mounting hole 92 for mounting at least one temperature sensor 91, and the second storage compartment 212 has at least one mounting hole 92 for mounting at least one temperature sensor 91, as shown. Figures 11 to 13 As shown, four temperature sensors 91 are circumferentially installed in the first storage compartment 211 and four temperature sensors 91 are circumferentially installed in the second storage compartment 212. A first connector 13 is used for electrical connection to a power source and is also electrically connected to the fluid delivery device 27. A second connector 24 is electrically connected to the cooling chip 225 and the temperature sensors 91. When the storage module 20 slides into the receiving space 11, the first connector 13 and the second connector 24 simultaneously complete the connection. In this way, the temperature sensors 91 detect the temperature of the first storage compartment 211 and the second storage compartment 212.

[0072] When the refrigeration temperature of the first storage compartment 211 drops to the lower limit of the preset refrigeration threshold range, the control module controls the cooling element 225 to be de-energized. The cooling side then stops absorbing heat and performing work. However, due to the large temperature difference between the heating and cooling sides, the temperature of the heating side is higher, and the control module continues to control the fluid delivery device 27 to deliver fluid, thus maintaining heat transfer to the second storage compartment 212. When the refrigeration temperature of the first storage compartment 211 rises to the upper limit of the preset refrigeration threshold range, the control module controls the cooling element 225 to be energized again, and the cooling side absorbs heat and performs work to cool the first storage compartment 211 until the refrigeration temperature of the first storage compartment 211 drops to the lower limit of the preset refrigeration threshold range. This achieves constant-temperature refrigerated storage in the first storage compartment 211.

[0073] When the heating temperature of the second storage chamber 212 rises to the upper limit of the preset heating threshold range, the control module controls the first valve 41 to close and the second valve 42 to open. At this time, the heat dissipation outlet 2261 is connected to the external environment through the first outlet 17 of the support frame 10, which is equivalent to stopping the heating of the second storage chamber 212. When the heating temperature of the second storage chamber 212 drops to the lower limit of the preset heating threshold range, the control module controls the first valve 41 to open and the second valve 42 to close, thus reheating the second storage chamber 212 until the heating temperature of the second storage chamber 212 rises to the upper limit of the preset heating threshold range. In this way, the second storage chamber 212 can be heated and stored at a constant temperature.

[0074] According to a second aspect of this application, a delivery robot is provided, which includes the storage compartment structure as described above. Furthermore, the fluid outlet 16 of the support frame 10 communicates with the first outlet 17 to the exterior of the delivery robot's body.

[0075] The delivery robot of this application also includes a chassis motion module, a main control module, and an autonomous navigation module. The main body is mounted on the chassis motion module, and both the main control module and the autonomous navigation module are mounted on the main body. The chassis motion module's walking system is electrically connected to the autonomous navigation module, the main control module is electrically connected to the autonomous navigation module, and the main control module is electrically connected to the control system of the aforementioned storage compartment structure. Specifically, the main control module collects and calculates data sent by the autonomous navigation module and data sent by the control system. The delivery robot first walks empty through the work area. During this process, the autonomous navigation module scans the walking route of the work area and sends it to the main control module for storage. When an item is placed in the storage module of the delivery robot and needs to be delivered to the target location, the main control module sends a navigation command to the autonomous navigation module. The autonomous navigation module controls the chassis motion module's walking system to move along the walking route. During the movement, the autonomous navigation module detects obstacles on the walking path in real time and sends data to the main control module. The main control module receives and calculates the data and sends an obstacle avoidance command to the autonomous navigation module. The autonomous navigation module controls the walking system to avoid obstacles until the target location is reached. As the delivery robot travels to its target location, the main control module controls the control system to monitor the cooling and heating effects of the storage module on the stored items in real time.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
