[0033] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0034] First, the application scenarios to which this application is applicable are introduced. This application is applied to the field of robots. Specifically, the robot in the embodiment of this application is a delivery robot, which is used to transport delivery items to delivery points. As an intelligent device that replaces manual delivery services, it can not only bring customers a novel experience, but also reduce manual labor intensity and improve work efficiency. It has been increasingly used in canteens, restaurants, hotels and other places.

[0035] However, research has found that when existing delivery robots are performing delivery tasks, different types of delivery items will affect the environment in the delivery cabin, which may in turn contaminate subsequent delivery items.

[0036] Based on this, an embodiment of the present application provides a delivery robot that can solve the problem in the prior art that items in the delivery cabin are easily contaminated.

[0037] See also Figure 1 , Figure 1 A schematic diagram of the appearance structure of a delivery robot provided in an embodiment of the present application; Figure 2 A schematic diagram of the internal cabin structure of a delivery robot provided in an embodiment of the present application. Figure 1 and Figure 2As shown in the figure, the delivery robot provided by the embodiment of the present application includes: a mobile chassis 1 and a body 2 arranged on the mobile chassis; the mobile chassis 1 is connected to the body 2 to drive the body 2 to move synchronously; the body 2 is a cavity structure formed by the material, and a cabin 21 for carrying delivery items is arranged therein, and there is no restriction on the type of delivery items; a disinfection module 23 is arranged in the cabin 21, and is used to disinfect the environment in the cabin.

[0038] Continue reading Figure 3 , Figure 3 This is one of the circuit structure diagrams of a delivery robot provided in an embodiment of the present application. Figure 3 As shown in , the delivery robot provided in the embodiment of the present application further includes: a charging interface 5, a chassis controller 6 and a host computer 7. Specifically, one end of the chassis controller 6 is connected to one end of the host computer 7, and the other end of the host computer 7 is connected to the disinfection module 23; the other end of the chassis controller 6 is connected to the charging interface 5; and the charging interface 5 is used to connect to the charging pile 8.

[0039] During the charging process, the delivery robot is connected to the charging pile 8 through the charging interface 5, and the charging pile 8 outputs charging power to the delivery robot through the charging interface 5. When the delivery robot is electrically connected to the charging pile 8 through the charging interface 5, and the chassis controller 6 detects the charging voltage signal output by the charging pile 8 to the delivery robot through the charging interface 5, the chassis controller 6 can read the pre-stored charging status signal and send it to the host computer 7. Here, the charging status signal can indicate the charging status of the delivery robot, such as charging; the implementation method of the chassis controller 6 reading the pre-stored signal and sending the signal can refer to the implementation method in the prior art, and this application does not impose any restrictions here.

[0040] After receiving the charging status signal, the host computer 7 can read the pre-stored disinfection control instructions and send them to the disinfection module 23; wherein, the implementation method of the host computer 7 reading the pre-stored instructions and sending the instructions can also refer to the implementation method in the prior art, and this application does not impose any restrictions here.

[0041] After receiving the disinfection control instruction, the disinfection module 23 starts disinfecting the cabin 21 under the drive of the disinfection control instruction.

[0042] Optionally, the disinfection module 23 can be an ultraviolet lamp, which is arranged on the inner wall of the cabin 21 and disinfects the cabin 21 environment and the delivered items by emitting ultraviolet rays into the internal space of the cabin 21; or, the disinfection module 23 can also be other equipment that can sterilize and disinfect, such as an ozone sterilizer, etc., and the present application does not impose any restrictions here.

[0043] In this way, when connected to the charging pile for charging, the disinfection module uses the charging time to fully disinfect the cabin used to carry out delivery items, so as to ensure the cleanliness of the cabin and the safety of the delivery items; on the other hand, charging and disinfection are carried out at the same time, which meets the needs of the robot to automatically charge after a day's work or during a long period of idle time. During the automatic charging process, the disinfection module is automatically turned on to give the machine cabin sufficient time to disinfect, which can ensure the robot's endurance and avoid the robot frequently starting the disinfection module while performing delivery tasks. For example, avoid turning on the disinfection module while waiting for delivery tasks. If there are many tasks, the disinfection time is short and the disinfection and sterilization requirements cannot be met. Since the disinfection module is a high-power device, when there are many tasks while waiting for the task, frequently turning on the disinfection light module will greatly reduce the machine's endurance and lead to the problem of excessive power consumption.

[0044] Continue reading Figure 4 , Figure 4 This is a circuit structure diagram of a delivery robot provided in an embodiment of the present application. Figure 4 As shown in , the chassis controller 6 includes an oscillation circuit 61, an analog-to-digital converter 62 and a single-chip microcomputer 63; one end of the analog-to-digital converter 62 is connected to one end of the single-chip microcomputer 63, and the other end of the single-chip microcomputer 63 is connected to the host computer 7; the other end of the analog-to-digital converter 62 is connected to the charging interface 5, and the oscillation circuit 61 is connected to the charging interface 5.

[0045] The oscillation circuit 61 is used to send an oscillating square wave to the charging pile 8 through the charging interface 5 after the delivery robot is connected to the charging pile 8 through the charging interface 5. Here, when the charging interface 5 of the delivery robot is in stable contact with the charging pile 8, the oscillation circuit 61 will generate an oscillating square wave of a certain frequency and output it to the charging pile 8. After receiving the oscillating square wave, the charging pile 8 will turn on the internal power switch, and then output the charging voltage to charge the delivery robot.

[0046] The analog-to-digital converter 62 (Charge_ADC) is an electronic device for converting a continuous signal in analog form into a discrete signal in digital form. In this embodiment, the analog-to-digital converter 62 collects the analog charging voltage signal output by the charging pile 8 in response to the oscillating square wave through the charging interface 5, converts the analog charging voltage signal into a digital charging voltage signal, and sends the digital charging voltage signal to the single-chip microcomputer 63.

[0047] The single-chip microcomputer 63 (MCU) sends a charging status signal to the host computer 7 when receiving the digital charging voltage signal. Here, when the single-chip microcomputer 63 receives the digital charging voltage signal through the corresponding input pin, it indicates that the charging pile 8 is charging the delivery robot. The single-chip microcomputer 63 can read the pre-stored charging status signal and send it to the host computer 7 through the corresponding output pin to notify the host computer 7 that the delivery robot is charging. More specifically, after the delivery robot is connected to the charging pile 8, the specific way in which the chassis controller 6 outputs the charging status signal can be implemented based on the charging protocol in the prior art, and this application does not impose any restrictions here.

[0048] Through this architecture, the chassis controller can determine in a timely and accurate manner that the delivery robot is in charging status, and then notify the host computer.

[0049] Furthermore, the host computer 7 includes a robot whole machine control circuit 71, a display screen control circuit 72 and a peripheral control circuit 73; one end of the robot whole machine control circuit 71 is connected to the chassis controller 6, specifically the single chip microcomputer 63 in the chassis controller 6; the other end of the robot whole machine control circuit 71 is connected to one end of the display screen control circuit 72; the other end of the display screen control circuit 72 is connected to one end of the peripheral control circuit 73; the other end of the peripheral control circuit 73 is connected to the disinfection module 23.

[0050] The robot whole machine control circuit 71, which serves as the control center of the robot whole machine, can run a whole machine control application program; in the embodiment of the present application, based on the transparent transmission function, the received charging status signal is directly forwarded to the display screen control circuit 72.

[0051] The display screen control circuit 72 is connected to the display screen 41 of the delivery robot, and the display screen control circuit 72 can run a display screen control application; after receiving the charging status signal, the display screen 41 is controlled to display a pre-set charging interactive interface; at the same time, the charging status signal continues to be forwarded to the peripheral control circuit 73.

[0052] The peripheral control circuit 73 is connected to various external hardware devices of the delivery robot, such as the disinfection module 23, the lighting strip, etc. The peripheral control circuit 73 can run a peripheral control application program, and after receiving the charging status signal, it can read the pre-stored disinfection control instructions and send them to the disinfection module 23.

[0053] More specifically, the specific method in which the display screen control circuit 72 transmits instructions to the display screen 41 and the peripheral control circuit 73 transmits instructions to the disinfection module 23 can be implemented based on the communication data protocol in the prior art, and this application does not impose any limitations here.

[0054] In this way, under the upper computer architecture of the robot control circuit, display control circuit and peripheral control circuit, different robot components can be controlled by distributing signals and instructions step by step, which can adapt to the current more complex robot structure and achieve more comprehensive and intelligent control.

[0055] Optional, return to see Figure 1 and Figure 2 The delivery robot also includes a head 4, on which a display screen 41 is provided; the display screen 41 can realize human-machine interaction, for example, an interactive interface can be displayed on the display screen 41, through which control instructions input by the user are received, and various status information of the robot is displayed, such as the type of delivered items, the delivery destination, and the cabin disinfection status information. Exemplarily, during the charging process, the display screen 41 displays a charging interactive interface, in which cabin disinfection status information is displayed, and the cabin disinfection status information may include whether disinfection is in progress, the disinfection duration, and the power of the disinfection module.

[0056] Through the display screen, users can intuitively understand the current cabin disinfection status of the delivery robot, thereby improving the intelligence level of the delivery robot.

[0057] Optional, such as Figure 1 As shown in , the cabin 21 has a door 3 for opening or closing the cabin 21. The cabin door 3 can be closed to form a closed environment in the cabin 21 to reduce the pollution of the external environment to the delivered items. The cabin door 3 can be opened and closed automatically or manually.

[0058] The delivery robot further includes a door sensor (not shown in the figure), which is arranged on the door 3 and connected to the host computer 7. The door sensor is used to detect the switch signal of the door 3 and send the switch signal to the host computer 7. The door sensor may include at least one of the following: a camera, an infrared sensor and a laser radar.

[0059] When the host computer 7 receives a switch signal indicating that the cabin door 3 is open, it can control the disinfection module 23 to stop the disinfection work; thereafter, if the host computer 7 receives a closing signal indicating that the cabin door 3 is closed again, it can control the disinfection module 23 to continue the disinfection work.

[0060] Furthermore, before driving the disinfection module 23 to perform the disinfection work, the host computer 7 can detect whether the cabin door 3 is closed; when the cabin door 3 is closed, a disinfection control instruction is sent to drive the disinfection module 23 to disinfect the cabin 21.

[0061] In this way, through the cabin door sensor, the start and stop of the disinfection module can be controlled according to the cabin door switch status. When the cabin door is opened, the disinfection work of the disinfection module is automatically stopped, and when the cabin door is closed, the disinfection work of the disinfection module is automatically continued. While avoiding the impact of the disinfection equipment on the human body, the continuity of the disinfection work is guaranteed and the disinfection effect is improved.

[0062] In one example, an undivided integral distribution space may be formed in the cabin 21 ; in this case, the disinfection module 23 may be disposed on the inner wall at the top of the cabin 21 to fully disinfect the entire cabin 21 .

[0063] In another example, at least one storage layer 22 may be provided in the compartment 21 to form at least two sub-compartments. Figure 2 As shown in the figure, two storage layers 22 are arranged in the cabin 21 to form three sub-cabins, so as to improve the storage capacity of the cabin space and reduce the cross-influence of the delivered items between different sub-cabins.

[0064] At this time, the disinfection module 23 can be set at the bottom of the storage layer 22 between every two adjacent sub-chambers, or the disinfection module 23 can be set at the top of the cabin 21 and the bottom of the storage layer 22 between every two adjacent sub-chambers, so as to comprehensively disinfect each sub-chamber, making the disinfection more comprehensive and thorough.

[0065] The number, specific installation position and installation method of the disinfection modules 23 can be set as needed, and this application does not impose any restrictions here. As an example, considering that the frequency of use of the first-layer sub-cabin is high in practice, in order to achieve sufficient disinfection, at least two disinfection modules 23 are arranged at the top of the cabin 21; at least one disinfection module 23 is arranged at the bottom of the storage layer 22 between every two adjacent sub-cabins. That is, at least two disinfection modules 23 are arranged in the first-layer sub-cabin, and at least one disinfection module 23 is arranged in each of the other layers of sub-cabins.

[0066] Furthermore, the host computer 7 can also control the start and stop of the disinfection module 23 by detecting whether the disinfection effect meets the preset conditions. Specifically, when it is determined that the disinfection effect meets the preset conditions, the disinfection module 23 is controlled to stop the disinfection work; otherwise, the disinfection work continues. Among them, the preset conditions can be that the disinfection time reaches the preset time, the concentration of the disinfectant reaches the preset concentration, etc., which will not be explained one by one here.

[0067] In one example, when the preset condition is that the disinfection time reaches the preset time, the delivery robot also includes a timing circuit (not shown in the figure); the timing circuit is connected to the host computer 7. The timing circuit triggers the timing when the disinfection module 23 disinfects the cabin 21, and generates a timing stop signal after the timing reaches the preset time and sends it to the host computer 7; when the host computer 7 receives the timing stop signal, it controls the disinfection module 23 to stop the disinfection work. Among them, the preset time can be set as needed, such as 1 hour, 15 minutes, and this application does not make any restrictions here. In this way, while ensuring a good disinfection effect on the cabin, it can reduce power consumption and save resources.

[0068] Furthermore, the chassis controller 6 is also used to send a charging stop signal to the host computer 7 when it is detected that the charging interface 5 is disconnected from the charging pile 8; the host computer 7 is also used to send a disinfection stop instruction to the disinfection module 23 after receiving the charging stop signal, so as to drive the disinfection module 23 to stop disinfecting the cabin 21. In this way, the disinfection module 23 can be turned off in time after the charging is completed and the delivery robot is disconnected from the charging pile 8 to ensure that charging and disinfection are carried out synchronously, avoiding the problem that the disinfection module 23 is frequently started during the delivery task, resulting in excessive power consumption and affecting the robot's endurance.

[0069] Further, regarding the timing of the host computer 7 starting disinfection, the host computer 7 may refer to the above description and immediately send a disinfection control instruction to drive the disinfection module 23 to disinfect the cabin 21 after receiving the charging status signal indicating charging, that is, after sensing that the charging pile 8 is charging; or send a disinfection control instruction to drive the disinfection module 23 to disinfect the cabin 21 when sensing that the charging pile 8 is charging and other conditions are met. Exemplarily, the preset condition may be that the cabin door 3 is detected to be closed, the charging reaches a preset ratio, etc.

[0070] A delivery robot provided in an embodiment of the present application includes: a mobile chassis, a fuselage arranged on the mobile chassis, a charging interface, a chassis controller, a host computer and a disinfection module; a cabin for carrying delivery items is arranged in the fuselage; one end of the chassis controller is connected to one end of the host computer, and the other end of the host computer is connected to the disinfection module; the disinfection module is arranged in the cabin; the other end of the chassis controller is connected to the charging interface; the charging interface is used to connect to a charging pile; the chassis controller is used to send a charging status signal to the host computer when the delivery robot is connected to the charging pile through the charging interface and detects the charging voltage signal output by the charging pile; the host computer is used to send a disinfection control instruction to the disinfection module after receiving the charging status signal, so as to drive the disinfection module to disinfect the cabin.

[0071] In this way, when the delivery robot is connected to the charging pile for charging, the disinfection module can use the charging time to fully disinfect the cabin used to carry the delivery items, thereby ensuring the cleanliness of the cabin and the safety of the delivery items. On the other hand, charging and disinfection are carried out simultaneously to ensure the robot's endurance and avoid the problem of excessive power consumption caused by frequent activation of the disinfection module during the delivery task.
