Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a small robot for transporting articles in a commercial building. Background Art

[0002] With the development of economy, the level of science and technology is also developing rapidly. Robots are mechanical devices that perform work automatically. They can accept human commands, run pre-programmed programs, and act according to the principles and guidelines formulated by artificial intelligence technology. In restaurants or cafes in business buildings, robots can provide food delivery services and deliver food to customers. In addition, robots can deliver mail and packages inside business buildings to improve work efficiency.

[0003] The existing patent (publication number: CN211483440U) discloses a food delivery robot, which has a certain heat preservation effect while preventing food contamination, buffering the unevenness of the ground, reducing bumps and shaking, and improving the stability of the robot during walking.

[0004] In view of the above problems, the existing patents provide solutions, but in order to improve the heat preservation effect during the transportation of meals, the meals need to be placed in a closed environment. However, for hot food just out of the pot, the higher the temperature of the soup, the more active the movement of the molecules. Therefore, the hot air and steam generated by the hot food contain volatile molecules of the food. These molecules move faster as the temperature rises, thereby diffusing into the air faster. Therefore, when the robot delivers meals continuously, the residual taste in the lunch box will mix with the new hot dishes, which will affect the taste and mouthfeel of the dishes.

[0005] Therefore, a small robot for transporting items in commercial buildings is proposed. Summary of the invention

[0006] The purpose of the utility model is to provide a small robot for transporting goods in a commercial building, which can solve the problem that when the robot continuously delivers meals, the residual taste in the meal box will be mixed with the new hot dishes, thus affecting the taste and mouthfeel of the dishes.

[0007] To achieve the above purpose, the utility model provides the following technical solutions: a small robot for transporting goods in a commercial building, comprising a base and:

[0008] The stabilizing mechanism comprises a telescopic rod, a cabinet body and a cabinet door; the telescopic rod is installed on the base, the cabinet body is installed on the output end of the telescopic rod, the cabinet body is used to load the dining tray, the cabinet door is movably arranged on the cabinet body, and the telescopic rod is used to lower the center of gravity;

[0009] The buffer mechanism comprises a mounting plate, a socket, a support rod, and a control assembly, wherein the sockets are evenly arranged on the mounting plate, the support rod is movably inserted into the sockets, the support rod is used to limit the position of the dining plate, and the control assembly is used to control the position of the support rod;

[0010] The heat preservation mechanism comprises a cavity, an air supply component and a pressure valve; the cavity is opened on the cabinet, the pressure valve is inserted on the side wall of the cavity, the air supply component is arranged on the cabinet, and the air supply component is used to provide hot air for the cavity.

[0011] Preferably, the control assembly comprises a magnet mounted on the base, and an elastic membrane is mounted on the top wall of the mounting plate, and the elastic membrane is used to drive the support rod to reset.

[0012] Preferably, the air supply assembly includes a bellows mounted on the telescopic rod, the two ends of the bellows are respectively connected to the cabinet and the base, a conduit is inserted on the top wall of the cabinet, the bottom end of the conduit is connected to the bellows, and an air intake valve is provided on the conduit, and an exhaust valve is inserted on the side wall of the bellows, and the output end of the exhaust valve is connected to the cavity.

[0013] When food needs to be transported by the robot, the telescopic rod is first in an extended state. At this time, the mounting plate is away from the base. The support rod falls into the socket under the action of the elastic force of the elastic membrane and its own gravity, and then the meal plate to be delivered is placed on the end of the support rod. After placing the meal plate, the cabinet door is closed to prevent heat loss from the meal. The telescopic rod then contracts to lower the center of gravity of the entire robot, thereby improving stability during transportation and reducing the probability of the robot shaking when accidentally touched by pedestrians. At this time, the support rod is close to the magnet on the base, so under the action of repulsive force, part of the support rod extends from the socket, thereby improving stability during transportation and preventing the meal plate from sliding. The support rod drives the elastic membrane to wrap the meal plate, thereby reducing the pressure on the side wall of the meal plate. During the contraction of the telescopic rod, the gas in the bellows flows into the cavity through the exhaust valve.

[0014] When the robot transports food to the customer's table, the telescopic rod extends. At this time, the bellows is in a negative pressure state, so that when the cabinet door is opened to take food, it can absorb hot air from the cabinet through the duct and the suction valve, and absorb the smell remaining in the cabinet. Therefore, when the food is transported again, it can prevent the food flavors from mixing together, thereby reducing the impact on the taste of the food.

[0015] When the food is transported again, the telescopic rod drops again, so that the hot air in the bellows can be discharged into the cavity, thereby heating the cabinet. Under the action of heat exchange, the heat preservation effect of the food is improved; and under the action of the pressure valve, the excess gas in the cavity can be discharged, ensuring that the gas in the bellows can enter the cavity normally.

[0016] Preferably, a baffle is installed on the inner top wall of the cabinet.

[0017] Since the density of hot air is relatively small, the diffusion range of the hot air can be limited by arranging a baffle on the inner top wall of the cabinet, thereby ensuring that the bellows can absorb the hot air and improving the utilization rate of the hot air flow.

[0018] Preferably, a connecting pipe extending to the surface of the mounting plate is inserted on the side wall of the cavity, and the thickness of the elastic membrane is 2-4 mm.

[0019] Since the elastic film is in close contact with the dinner plate, the heat exchange efficiency can be improved by making hot air contact with the thinner elastic film through the connecting pipe, thereby improving the heat preservation effect of the dinner plate.

[0020] Preferably, an elastic rod is installed on the top wall of the base, and a reflective tape is installed on the elastic rod.

[0021] When the robot moves, the reflective tape installed on the elastic rod swings, which can remind pedestrians around to avoid it and prevent the robot from colliding with pedestrians.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The present application sets a telescopic rod, a pressure valve, a bellows, a duct, and an air intake valve. During the contraction of the telescopic rod, the gas in the bellows flows into the cavity through the exhaust valve. When the robot transports the food to the customer's table, the telescopic rod extends, and the bellows is in a negative pressure state. Therefore, when the cabinet door is opened to take the food, hot air can be absorbed from the cabinet through the duct and the air intake valve, thereby absorbing the taste remaining in the cabinet.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figures 1 to 4 , the utility model provides a technical solution:

[0033] A small robot for transporting articles in a commercial building, comprising a base 1, and further comprising:

[0034] The stabilizing mechanism includes a telescopic rod 2, a cabinet body 3, and a cabinet door 4; the telescopic rod 2 is mounted on the base 1, the cabinet body 3 is mounted on the output end of the telescopic rod 2, the cabinet body 3 is used to load the dinner plate, the cabinet door 4 is movably arranged on the cabinet body 3, and the telescopic rod 2 is used to lower the center of gravity;

[0035] The buffer mechanism includes a mounting plate 5, a socket 6, a support rod 7, and a control component. The sockets 6 are evenly arranged on the mounting plate 5, the support rod 7 is movably inserted in the socket 6, the support rod 7 is used to limit the position of the dining plate, and the control component is used to control the position of the support rod 7;

[0036] The heat preservation mechanism includes a cavity 8, an air supply component, and a pressure valve 9; the cavity 8 is opened on the cabinet 3, the pressure valve 9 is inserted on the side wall of the cavity 8, the air supply component is arranged on the cabinet 3, and the air supply component is used to provide hot air for the cavity 8.

[0037] The control assembly includes a magnet 10 mounted on the base 1 , and an elastic membrane 11 is mounted on the top wall of the mounting plate 5 , and the elastic membrane 11 is used to drive the support rod 7 to reset.

[0038] The air supply assembly includes a bellows 12 sleeved on the telescopic rod 2, the two ends of the bellows 12 are respectively connected to the cabinet 3 and the base 1, a conduit 13 is inserted on the top wall of the cabinet 3, the bottom end of the conduit 13 is connected to the bellows 12, and an air intake valve 14 is provided on the conduit 13, and an exhaust valve 15 is inserted on the side wall of the bellows 12, and the output end of the exhaust valve 15 is connected to the cavity 8.

[0039] When it is necessary to transport food by the robot, the telescopic rod 2 is first in an extended state. At this time, the mounting plate 5 is away from the base 1. At this time, the support rod 7 falls into the socket 6 under the action of the elastic force of the elastic membrane 11 and its own gravity, and then the food plate to be delivered is placed on the end of the support rod 7. After placing the food plate, the cabinet door 4 is closed to prevent the heat loss of the food. Then the telescopic rod 2 is retracted to lower the center of gravity of the entire robot, thereby improving the stability during transportation and reducing the probability of the robot shaking when being accidentally touched by pedestrians. At this time, the support rod 7 is close to the magnet 10 on the base 1. Therefore, under the action of repulsive force, part of the support rod 7 extends from the socket 6, thereby improving the stability during transportation and preventing the food plate from sliding. The support rod 7 drives the elastic membrane 11 to wrap the food plate, which can reduce the pressure on the side wall of the food plate. During the contraction of the telescopic rod 2, the gas in the bellows 12 flows into the cavity 8 through the exhaust valve 15.

[0040] When the robot transports the food to the customer's table, the telescopic rod 2 extends. At this time, the bellows 12 is in a negative pressure state, so that when the cabinet door 4 is opened to take the food, hot air can be absorbed from the cabinet 3 through the duct 13 and the suction valve 14, and the taste remaining in the cabinet 3 can be absorbed. Therefore, when the food is transported again, the taste of the food can be prevented from mixing together, which plays a role in reducing the impact on the taste of the food.

[0041] When the food is transported again, the telescopic rod 2 is lowered again, so that the hot air in the bellows 12 can be discharged into the cavity 8, thereby heating the cabinet 3. Under the action of heat exchange, the heat preservation effect of the food is improved; and under the action of the pressure valve 9, the excess gas in the cavity 8 can be discharged, which ensures that the gas in the bellows 12 can enter the cavity 8 normally.

[0042] Specifically, Figure 4 As shown, a baffle 16 is installed on the inner top wall of the cabinet 3.

[0043] Since the density of hot air is relatively small, the diffusion range of the hot air can be limited by arranging a baffle 16 on the inner top wall of the cabinet 3, thereby ensuring that the bellows 12 can absorb the hot air and improving the utilization rate of the hot air flow.

[0044] Specifically, Figure 4 As shown, a connecting pipe 17 extending to the surface of the mounting plate 5 is inserted on the side wall of the cavity 8, and the thickness of the elastic membrane 11 is 2-4 mm.

[0045] Since the elastic film 11 is in close contact with the dinner plate, the hot air is brought into contact with the thin elastic film 11 through the connecting pipe 17, so that the heat exchange efficiency can be improved, thereby improving the heat preservation effect on the dinner plate.

[0046] Specifically, Figure 1As shown, an elastic rod 18 is installed on the top wall of the base 1, and a reflective tape 19 is installed on the elastic rod 18.

[0047] When the robot moves, the reflective tape 19 installed on the elastic rod 18 swings, thereby prompting pedestrians around to avoid it, thereby preventing the robot from colliding with pedestrians.

[0048] Working principle: When it is necessary to transport food by the robot, the telescopic rod 2 is first in an extended state. At this time, the mounting plate 5 is away from the base 1. At this time, the support rod 7 falls into the socket 6 under the action of the elastic force of the elastic membrane 11 and its own gravity, and then the food plate to be delivered is placed on the end of the support rod 7. After placing the food plate, the cabinet door 4 is closed to prevent the heat loss of the food. Then the telescopic rod 2 contracts to lower the center of gravity of the entire robot, thereby improving the stability during transportation and reducing the probability of the robot shaking when accidentally touched by pedestrians. At this time, the support rod 7 is close to the magnet 10 on the base 1. Therefore, under the action of repulsive force, part of the support rod 7 extends from the socket 6, thereby improving the stability during transportation and preventing the food plate from sliding. The support rod 7 drives the elastic membrane 11 to wrap the food plate, which can reduce the pressure on the side wall of the food plate; during the contraction of the telescopic rod 2, the gas in the bellows 12 flows into the cavity 8 through the exhaust valve 15.

[0049] When the robot transports the food to the customer's table, the telescopic rod 2 extends. At this time, the bellows 12 is in a negative pressure state, so that when the cabinet door 4 is opened to take the food, hot air can be absorbed from the cabinet 3 through the duct 13 and the suction valve 14, and the taste remaining in the cabinet 3 can be absorbed. Therefore, when the food is transported again, the taste of the food can be prevented from mixing together, which plays a role in reducing the impact on the taste of the food.

[0050] When the food is transported again, the telescopic rod 2 is lowered again, so that the hot air in the bellows 12 can be discharged into the cavity 8, thereby heating the cabinet 3. Under the action of heat exchange, the heat preservation effect of the food is improved; and under the action of the pressure valve 9, the excess gas in the cavity 8 can be discharged, which ensures that the gas in the bellows 12 can enter the cavity 8 normally.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
