[0024] In one embodiment, Figure 1-Figure 6 As shown, a food delivery service robot comprises a moving seat 1, a base 2 is rotatably mounted on the upper end of the moving seat 1, support blocks 3 are symmetrically fixed on both sides of the upper end of the base 2, a placement piece 5 is arranged between the two support blocks 3, adjustment grooves 31 are symmetrically opened at the opposite ends of the two support blocks 3, and adjustment structures 4 for adjusting the position of the placement piece 5 are arranged inside the two adjustment grooves 31, a motor 12 is arranged inside the moving seat 1, the output end of the motor 12 is fixed to the base 2, and a plurality of universal wheels 11 are installed at the bottom end of the moving seat 1.
[0025] In this embodiment, when in use, the plates to be delivered are placed on the placement piece 5 in turn, and the robot can be transported to the dining table where the food needs to be served through the universal wheel 11. The plate placed on the top of the food delivery robot is the food for this table. When the plates of a table are taken, the adjustment structure 4 drives the rotating piece to rotate, and the rotating piece drives the placement piece 5 to rotate, and another group of placement pieces 5 are rotated to the top of the food delivery robot. The motor 12 can adjust the rotation of the base 2 and its upper components, so as to facilitate the next delivery and the next meal collection.
[0026] In an optional embodiment, the adjustment structure 4 includes a gear 1 401 rotatably mounted at the center of the adjustment groove 31, an inner toothed ring 403 is fixed to the inner wall of the adjustment groove 31, four gears 2 402 are distributed on the inner circumference of the adjustment groove 31, and the four gears 2 402 are all meshed with the gear 1 401 and the inner toothed ring 403, and a fixed shaft 406 is fixed to the middle of one end of the four gears 2 402 close to another support block 3, and a rotating disk 404 is fixed to one end of the gear 1 401 close to another support block 3. A cross connecting rod 405 is fixed to one end of the rotating disk 404 away from the gear one 401, and the four ends of the cross connecting rod 405 are rotatably connected to the outer walls of four fixed shafts 406 respectively. A balance rod 407 rotatably installed on the outer wall of one of the fixed shafts 406 is also rotatably connected to another adjacent fixed shaft 406, and a placement piece 5 is rotatably installed on the other end of the fixed shaft 406. A motor two 41 is installed on the outer wall of one of the support blocks 3, and the output end of the motor two 41 extends to the inside of the adjustment slot 31 and is fixedly connected to the gear one 401.
[0027] It should be noted that the motor 2 41 drives the gear 1 401 inside the adjustment slot 31 provided in the support block 3 to rotate, and the rotation of the gear 1 401 will drive the four gears 2 402 meshing with it to rotate, and these four gears 2 402 are not only meshed with the gear 1 401, but also meshed with the inner gear ring 403. The inner gear ring 403 is fixed on the inner wall of the adjustment slot 31, providing a stable rotation track for the gear 2 402. Through this design, the gear 2 402 can rotate stably and synchronously around the gear 1 401 as the center. The rotation of the gear 2 402 will drive the fixed shaft 406 to rotate, and the fixed shaft 406 is connected to the placement piece 5. In order to ensure that the four placement pieces 5 can rotate synchronously and smoothly, the cross connecting rod 405 is designed to connect the gear 1 401 and the four fixed shafts 406. In this way, when the gear 1 401 rotates, the cross connecting rod 405 will drive the four fixed shafts 406 to rotate synchronously. In addition, a balance pole 407 is installed between adjacent fixed shafts 406 to further ensure stability and balance during rotation.
[0028] In an optional embodiment, the placement member 5 includes a placement block 501, both ends of the placement block 501 are rotatably connected to the fixed shaft 406, the upper end of the placement block 501 is hingedly installed with a placement cover 502, the inside of the placement block 501 is provided with a battery cavity 503 for installing a battery 504, and the upper end of the placement block 501 is provided with a heating structure 51 and a blowing structure 52.
[0029] It should be noted that the meal tray is placed on the placement block 501, and the placement cover 502 is closed during the meal delivery process, so as to prevent dust and some impurities from falling into the meal tray during the meal delivery process, thereby affecting the customer's appetite.
[0030] In an optional embodiment, the heating structure 51 includes a heating groove 511 opened at the upper end of the placement block 501, a heating groove 512 is opened at the bottom of the heating groove 511, a plurality of heating rods 516 are arranged at the middle position inside the heating groove 512, and the plurality of heating rods 516 are electrically connected to the battery 504, springs 515 are symmetrically fixed on both sides inside the heating groove 512, the upper ends of the springs 515 are fixedly connected to the insulation block 514, a heat conductive block 513 is arranged in the middle position of the insulation block 514, a trigger button 517 is arranged at the upper end of the heating groove 511, the trigger button 517 is electrically connected to the heating rod 516, and the upper end of the insulation block 514 is connected to the blowing structure 52.
[0031] It should be noted that when the dinner plate is placed on the insulation block 514, the dinner plate presses down the insulation block 514, the spring 515 is compressed, and the insulation block 514 moves downward, pressing the trigger button 517, and the trigger button 517 starts the heating rod 516, and the heating rod 516 starts working. The heat-conducting block 513 in the middle position of the insulation block 514 transfers the heat generated by the operation of the heating rod 516 to the dinner plate, thereby heating and keeping the food on the dinner plate warm.
[0032] In an optional embodiment, the blowing structure 52 includes a side groove 521 opened inside the placement block 501, and a baffle 523 is slidably installed inside the side groove 521. The two sides of the bottom end of the baffle 523 are fixedly connected to the upper end of the insulation block 514 through connecting blocks 522. A fan cavity 524 is opened inside the side groove 521, and a plurality of hair dryers 525 are installed inside the fan cavity 524. The plurality of hair dryers 525 are electrically connected to the battery 504, and a filter plate 526 is installed at one end of the fan cavity 524 close to the side groove 521.
[0033] It should be noted that when the dinner plate is placed on the insulation block 514, the insulation block 514 moves downward, and the baffle 523 is pulled downward by the connecting block 522. The baffle 523 blocks the filter plate 526, effectively blocking the airflow generated by the hair dryer 525, thereby preventing the temperature of the food from dropping. When the dinner plate is taken away, the spring 515 rebounds, and the baffle 523 cannot block the hair dryer 525 inside the fan cavity 524. The wind force generated by the fan cavity 524 passes through the filter plate 526 and enters the position of the insulation block 514, which not only effectively dispels the residual odor, but also avoids the odor crosstalk that may be generated between the previous and next dishes, thereby ensuring that the taste and smell of each dish are presented to the diners.
[0034] In an optional embodiment, a temperature sensor 53 is installed at one end of the side groove 521 close to the insulation block 514 , and the temperature sensor 53 is electrically connected to the battery 504 .
[0035] It should be noted that when the dinner plate is placed on the heat-insulating block 514, the temperature sensor 53 will immediately start working and continuously monitor the temperature of the dinner plate. Once the temperature of the dinner plate reaches the preset upper limit of the heating temperature, the temperature sensor 53 will send a signal to the control system, and the storage battery 504 will stop supplying power to the heating rod 516, and the heating rod 516 will stop heating, ensuring that the temperature of the dinner plate will not continue to rise, thereby avoiding the loss of taste and nutritional value that may be caused by overheating of the food.
[0036] The above embodiment discloses a meal delivery service robot, wherein the robot moves through the universal wheels 11 at the bottom thereof, and can flexibly deliver the meal tray to the designated table. The motor 12 drives the base 2 and the components at the upper end thereof to rotate, so as to adjust the meal delivery direction or prepare for the next meal delivery.
[0037] The dinner plate is placed on the placement member 5, specifically on the placement block 501, and is closed by a placement cover 502 to prevent dust and impurities from falling in.
[0038] When the meal tray needs to be switched, the motor 2 41 drives the gear 1 401 to rotate, thereby driving the four gears 2 402 to rotate synchronously. The gear 2 402 is connected to the placement member 5 through the fixed shaft 406, so the placement member 5 will rotate accordingly to achieve the switching of the meal tray.
[0039] When the dinner plate is placed on the heat insulating block 514, the dinner plate presses down the heat insulating block 514, the spring 515 is compressed, and the heat insulating block 514 presses the trigger button 517. The trigger button 517 activates the heating rod 516, and the heating rod 516 starts to work and transfers heat to the dinner plate through the heat conducting block 513 to heat and keep the food warm.
[0040] The temperature sensor 53 continuously monitors the temperature of the dinner plate, and once the preset upper heating temperature limit is reached, a signal is sent to the control system to stop supplying power to the heating rod 516 to prevent overheating of the food.
[0041] When the dinner plate is placed on the insulation block 514, the insulation block 514 pulls the baffle 523 downward through the connecting block 522, and the baffle 523 blocks the filter plate 526, effectively blocking the airflow generated by the hair dryer 525, thereby preventing the temperature of the dishes from dropping. When the dinner plate is taken away, the spring 515 rebounds, and the baffle 523 cannot block the hair dryer 525 inside the fan chamber 524. The wind force generated by the hair dryer 525 passes through the filter plate 526 and enters the location of the insulation block 514. Blowing air not only effectively dispels residual odors, but also avoids possible odor crosstalk between previous and next dishes, thereby ensuring the taste and smell of each dish.
[0042] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
