[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a distribution robot for a restaurant as shown in Figures 1 to 4 which includes a robot body 1. A plurality of storage cavities 2 are formed in the robot body 1, and a plurality of trays 3 are arranged in layers in each storage cavity 2. Each tray 3 is horizontally arranged and is slidably clamped with the robot body 1.

[0022] Taking one tray 3 as an example, two dust-proof and heat-insulating covers 4 are slidably assembled on the top of the tray 3. The two dust-proof and heat-insulating covers 4 are symmetrically distributed. The tray 3 is used to place dinner plates, and the dinner plates are located between the two dust-proof and heat-insulating covers 4, so as to keep the food on the dinner plates clean and warm.

[0023] Two opposed limiting sliding grooves are chiseled horizontally on the tray 3, and a slider 8 is slidably and limitedly fitted in each of the two limiting sliding grooves. The two sliders 8 correspond to the two dust-proof and heat-insulating covers 4 one by one, and each slider 8 is fixedly connected to the corresponding dust-proof and heat-insulating cover 4.

[0024] Each limiting sliding groove includes a first sliding groove 201 and a second sliding groove 202. The first sliding groove 201 is a vertical groove with the groove opening facing upwards. The second sliding groove 202 is a horizontal groove. The first sliding groove 201 and the second sliding groove 202 cross each other to form a horizontally arranged limiting sliding groove.

[0025] The slider 8 matches the limiting sliding groove for smooth sliding.

[0026] A thrust member is assembled on the tray 3. The thrust member is drivingly connected to the two dust-proof and heat-insulating covers 4 for pushing the two dust-proof and heat-insulating covers 4 to close.

[0027] The thrust member includes two second springs 15. The two second springs 15 correspond to the two limiting sliding grooves one by one. Each second spring 15 is located in the corresponding limiting sliding groove. The two second springs 15 correspond to the two dust-proof and heat-insulating covers 4 one by one. Each second spring 15 is arranged along the sliding direction of the corresponding dust-proof and heat-insulating cover 4. The two second springs 15 are both fixedly connected to the tray 3, and the movable ends are both fixedly connected to the slider 8 connected to the corresponding dust-proof and heat-insulating cover 4.

[0028] According to the actual use situation, the number of the second springs 15 connected to each slider 8 can be increased.

[0029] A mounting plate 12 is fixedly welded to the bottom of the tray 3, and a tension member is assembled on the mounting plate 12. The tension member is drivingly connected to two dust-proof and heat-insulating covers 4 for pulling the two dust-proof and heat-insulating covers 4 apart.

[0030] The tension member includes a motor 11, and the motor 11 is bolted to the mounting plate 12. Two wire wheels 10 are fixedly sleeved on the output shaft of the motor 11. A pulling rope 16 is fixedly connected to each of the two wire wheels 10, and each pulling rope 16 is wound around the corresponding wire wheel 10. The two pulling ropes 16 correspond to the two dust-proof and heat-insulating covers 4 one by one, and the movable end of each pulling rope 16 is fixedly connected to the slider 8 connected to the corresponding dust-proof and heat-insulating cover 4.

[0031] The motor 11 is a stepping motor to ensure self-locking.

[0032] Two pulley assemblies are assembled on the tray 3. The two pulley assemblies correspond to the two pulling ropes 16 one by one. Each pulling rope 16 is wound around the corresponding pulley assembly and is in rolling contact with the corresponding pulley assembly, facilitating the movement of the pulling rope 16 and ensuring the tension state of the pulling rope 16.

[0033] Each pulley assembly includes a first pulley 6 and a second pulley 7. Each first pulley 6 and each second pulley 7 are rotatably connected to the tray 3. A first pulley 6 is assembled in each limiting chute, and each second pulley 7 is assembled at the bottom of the tray 3. Each pulling rope 16 sequentially bypasses the corresponding second pulley 7 and first pulley 6, and at the same time, each pulling rope 16 slides into the limiting chute where the corresponding first pulley 6 is located.

[0034] A limiting member is assembled on the top of the tray 3. The limiting member is in driving cooperation with the two dust-proof and heat-insulating covers 4 and is also in limiting cooperation with the dinner plate. It is used to clamp and fix the dinner plate to prevent the food from spilling due to sliding during meal delivery.

[0035] The limiting member includes two symmetrically distributed clamping plates 13, and the two clamping plates 13 are both slidably connected to the tray 3. At the same time, the two clamping plates 13 correspond to the two dust-proof and heat-insulating covers 4 one by one, and each clamping plate 13 is arranged along the sliding direction of the corresponding dust-proof and heat-insulating cover 4. A sliding rod 14 is fixedly connected to the opposite ends of the two clamping plates 13, and the sliding rod 14 on each clamping plate 13 slides through the corresponding dust-proof and heat-insulating cover 4. A limiting plate 5 is installed at the end of each sliding rod 14 away from the connected clamping plate 13. The limiting plate 5 is in limiting cooperation with the dust-proof and heat-insulating cover 4 to prevent the sliding rod 14 from sliding out of the clamping plate 13.

[0036] A first spring 9 is sleeved on each sliding rod 14. One end of the first spring 9 is fixedly connected to the clamping plate 13, and the other end of the first spring 9 is fixedly connected to the dust-proof and heat-insulating cover 4.

[0037] The two clamping plates 13 are adapted to the dinner plate, and the dinner plate is located between the two clamping plates 13 to ensure stable clamping of the dinner plate.

[0038] Working principle: When the delivery robot delivers food, the motor 11 is started. The output shaft of the motor 11 drives the two wire wheels 10 to rotate, and the two wire wheels 10 wind up the two pull ropes 16. The two pull ropes 16 pull the two sliders 8 to slide away along the limit chute, and the two sliders 8 drive the two dust-proof and heat-insulating covers 4 to move apart.

[0039] During this process, the two dust-proof and heat-insulating covers 4 push the two limit plates 5 to move away, the two limit plates 5 pull the two sliding rods 14 to move away, and the two sliding rods 14 drive the two clamping plates 13 to slide away. At the same time, the two sliders 8 compress the two second springs 15.

[0040] When the dinner plate can pass between the two dust-proof and heat-insulating covers 4 and the dinner plate can be placed between the two clamping plates 13, the motor 11 is shut down, and the output shaft of the motor 11 stops rotating.

[0041] Then place the dinner plate between the two clamping plates 13. After that, start the motor 11 again, and the output shaft of the motor 11 rotates in reverse. At this time, under the elastic force of the two second springs 15, the two sliders 8 slide close and drive the two dust-proof and heat-insulating covers 4 to move close. At the same time, the two sliders 8 pull the two pull ropes 16 to be released from the wire wheels 10. During this process, the output shaft of the motor 11 rotates slowly to ensure that the two pull ropes 16 are always in a tensioned state to prevent the pull ropes 16 from detaching from the pulley assembly and the wire wheels 10.

[0042] During the process of the two dust-proof and heat-insulating covers 4 approaching and closing, the clamping plates 13 are pushed to slide close to the dinner plate by the first spring 9.

[0043] When the two clamping plates 13 contact the dinner plate, the two second springs 15 continue to overcome the elastic force of the two first springs 9 and continue to push the two dust-proof and heat-insulating covers 4 to slide close. During this process, the two first springs 9 are continuously compressed, and the clamping force of the two clamping plates 13 on the dinner plate gradually increases.

[0044] When the two dust-proof and heat-insulating covers 4 abut and close, the motor 11 is shut down. At this time, the elastic force of the two second springs 15 is still greater than the elastic force of the two first springs 9 to ensure the stability of the dinner plate.

[0045] When the dinner plate needs to be taken out, the motor 11 is started for the third time, and the output shaft of the motor 11 rotates in reverse relative to the second rotation. At this time, the two wire wheels 10 wind up the pull ropes 16, the two pull ropes 16 pull the two sliders 8 to slide away, and the two sliders 8 drive the two dust-proof and heat-insulating covers 4 to move apart.

[0046] During this process, the two first springs 9 extend, and the clamping force of the two clamping plates 13 on the dinner plate decreases. After the dust-proof and heat-insulating cover 4 contacts the limit plate 5, the limit plate 5 is pushed away from the dinner plate. The limit plate 5 drives the sliding rod 14 away from the dinner plate, and the sliding rod 14 drives the clamping plate 13 away from the dinner plate. When the dinner plate can be taken out between the two dust-proof and heat-insulating covers 4, turn off the motor 11 and take out the dinner plate.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
