[0002] Some invention patents in the field of food delivery robot technology are disclosed in the prior art, among which the invention patent with application number CN117359662B discloses a food delivery robot, including an automatic food delivery device and a base, with a box fixed on the top of the base. When the food delivery robot is in use, the meal plate is placed on a movable plate, and the movable plate moves downward through a pushing mechanism. When it moves upward, the infrared sensor controls and adjusts the position of the meal plate according to the size of the meal plate. When the meal plate is stored inside the storage cavity, the scattered soup drips into the collection box through a fixed pipe for collection, which is convenient for centralized cleaning later. Later, the movable seat is contacted with the fixed seat, and the conical groove wraps the storage cavity. After wrapping, the phenomenon of cross-flavor between the dishes is avoided, and a heating mechanism is installed on the movable plate, which heats the meal plate to avoid the food getting cold and affecting the taste later.

[0003] In the modern catering service process, after the food is carefully prepared, it needs to be properly placed in special tableware to ensure the appearance and taste of the food; then, the delicious food is efficiently and accurately delivered to the hands of customers using a delivery robot; however, in the actual delivery process, the robot faces a variety of complex environmental challenges. For example, the uneven ground, including uphill and downhill road conditions, and the accidental collision with other people or objects that may be encountered during the delivery process.

[0004] These factors may cause the food delivery robot to tilt during movement, or even cause food to fall or spill. In addition, the vibration generated when the robot is hit will cause the food in the tableware to shake, which in turn will cause the food to scatter, seriously affecting the visual effect and taste of the food. In response to these problems, the existing food delivery robot technology needs to be optimized to improve the stability and safety of the delivery process and ensure that customers can enjoy a high-quality dining experience.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In the present invention, the lower part of the movable frame adopts a conical structure, so that it can naturally maintain a vertical state during the movement of the robot. Thanks to the precise matching of the bearing and the rotating shaft, the movable frame can rotate flexibly in the bearing, and the gravity at the bottom of the movable frame ensures that the entire structure always remains vertical, thereby effectively avoiding the tilting of the tableware placed in the groove, and significantly reducing the risk of food spilling during transportation; in addition, in view of possible collisions, an interactive mechanism between the second guide block and the second guide groove is designed; when the storage box encounters a collision, the second guide block can slide smoothly in the second guide groove. At this time, the third elastic component and the fourth elastic component are pushed by the second guide block, playing a key buffering role, cleverly absorbing and dispersing the vibration energy, and greatly reducing the possibility of food shaking and falling in the tableware caused by collision; in summary, the innovative design of the present invention not only ensures that the food is not prone to tilting and spilling during transportation, but also significantly improves the stability and safety of the food delivery robot when facing complex environmental challenges, not only improves the quality of catering services, but also brings customers a more secure and pleasant dining experience.

[0029] 2. In the present invention, when the sliding cover slides to the left to open, the elastic force applied by the first elastic component to the first guide block ensures the stability of the guide block in the initial stage and avoids unnecessary displacement. As the first elastic component gradually extends and returns to its original length, the continued movement of the sliding cover will trigger the resetting action of the extrusion frame. This process is cleverly driven by the resilience of the first elastic component. At the same time, under the action of the second elastic component, the sliding plate and the movable frame can move upward smoothly, and the synchronous rise of the contact plate and the second sliding rod further ensures the vertical transportation of the dinner plate and the food. In this During the process, the gas inside the second piston cylinder is squeezed and flows into the first piston cylinder through the intermediate tube, increasing the internal air pressure. This air pressure change accurately controls the movement of the first piston plate, and then acts on the clamping plate through the first sliding rod to make it contact with the movable frame, thereby maintaining the stability of the movable frame. Not only does it make the operation of taking and placing meals extremely convenient, but it also greatly improves the stability of the operation. Whether in the startup stage of the meal delivery robot or in the process of transporting and taking and placing meals, the present invention can ensure the safety and appearance of meals and effectively prevent the tilting and spilling of meals.

[0044] Please see attached Figure 1 - Attachment Fig.11The present invention provides a technical solution: a food delivery robot, comprising a bottom support plate 1, a driving mechanism 2 is penetrated on the side of the bottom support plate 1, a bottom box 3 is installed on the bottom support plate 1, a storage basket 5 is penetrated on the front of the bottom box 3, a storage box 4 is fixedly connected to the bottom box 3, a sliding cover 6 is slidably connected to the storage box 4, two sliding grooves 11 are provided on the storage box 4, two sliding holes 12 that penetrate into the sliding grooves 11 are provided on the front and rear sides of the inner wall of the storage box 4, two first guide grooves 13 are provided under the sliding cover 6, a sliding adjustment mechanism 14 is provided in the first guide groove 13, a sliding support mechanism 15 is provided in the sliding hole 12, the two sliding support mechanisms 15 on the left side are arranged under the sliding adjustment mechanism 14, a connecting frame 16 located in the storage box 4 is fixedly installed on the back of the two sliding support mechanisms 15 on the front side, and the two A vertical plate 17 is installed on the opposite surface of each connecting frame 16, and a movable plate 18 is fixedly connected between the two vertical plates 17. Two second guide grooves 19 are provided on the opposite surfaces of the two vertical plates 17. Two sliding connection mechanisms 20 are slidably connected in the second guide grooves 19. A movable frame 21 is fixedly connected to the outside of the two sliding connection mechanisms 20 on the left side. Bearings 22 are provided on the front and rear sides of the movable frame 21. A rotating shaft 23 is rotatably connected in the bearing 22. A movable frame 24 is fixedly installed on the opposite surface of the two rotating shafts 23. Positioning blocks 26 are installed at the two diagonal positions on the inner side of the movable frame 21. A clamping and limiting mechanism 27 is fixedly connected to the side of the positioning block 26 close to the movable frame 24. An intermediate tube 28 is connected under the clamping and limiting mechanism 27, and the other end of the intermediate tube 28 is connected to an extrusion control mechanism 29 arranged in the storage box 4.

[0045] The bearing 22 and the rotating shaft 23 are used to make the movable frame 24 rotate in the movable frame 21. Since the center of gravity of the movable frame 24 is located below the rotating shaft 23, the movable frame 24 is kept in a vertical state, ensuring that the plate in the placement slot 25 is in a horizontal state.

[0046] Specifically, Figure 1-4 As shown, an electric hydraulic rod 10 is provided inside the sliding cover 6, and the other end of the electric hydraulic rod 10 is fixedly connected to the storage box 4. Two detection components 9 are installed on the right side of the storage box 4. A handle 7 is fixedly connected to the left side of the sliding cover 6. Two mesh plates 8 are penetrated through the sliding cover 6.

[0047] The electric hydraulic rod 10 controls the sliding cover 6 to move, thereby realizing the opening and closing process of the sliding cover 6;

[0048] Specifically, Figure 6 and Figure 8-9 As shown, a connecting groove 30 is opened under the movable plate 18, and the extrusion control mechanism 29 is arranged in the connecting groove 30. The lower half of the movable frame 24 is set to be conical, and the connection position between the rotating shaft 23 and the movable frame 24 is located on the upper side of the conical part. A placement groove 25 is opened on the movable frame 24.

[0049] Specifically, Figure 2 and Figure 4 As shown, the sliding adjustment mechanism 14 includes a first guide block 141 slidably connected in the first guide groove 13, a first elastic component 142 is fixedly connected to the side of the first guide block 141, the other end of the first elastic component 142 is connected to the first guide groove 13, a vertical rod 143 is fixedly connected under the first guide block 141, a pressing frame 144 is fixedly connected to the bottom end of the vertical rod 143, the side of the pressing frame 144 is set to be inclined, and the pressing frame 144 is arranged outside the sliding support mechanism 15.

[0050] The first guide groove 13 maintains the connection between the first guide block 141 and the extrusion frame 144 and the slide cover 6. The inclined surface of the extrusion frame 144 will press the contact rod 156 downward when it is close to the contact rod 156. When the slide cover 6 slides to the left to open, the elastic force applied by the first elastic component 142 to the first guide block 141 ensures the stability of the guide block in the initial stage and avoids unnecessary displacement. As the first elastic component 142 gradually extends and returns to its original length, the continued movement of the slide cover 6 will trigger the reset action of the extrusion frame 144.

[0051] Specifically, Figure 5-7 As shown, the sliding support mechanism 15 includes a sliding plate 151 slidably connected in the sliding hole 12, a sliding sleeve 152 is connected through the sliding plate 151, a fixed rod 153 is slidably connected in the sliding sleeve 152, the fixed rod 153 is fixedly connected in the sliding hole 12, and a contact rod 156 is fixedly connected to the side of the sliding plate 151 close to the sliding groove 11, and the contact rod 156 is arranged under the extrusion frame 144.

[0052] An intermediate rod 155 is fixedly connected to one side of the sliding plate 151 close to the storage box 4. The intermediate rod 155 is fixedly connected to the outside of the connecting frame 16. A second elastic component 154 is provided on the outer sleeve of the fixed rod 153. The other end of the second elastic component 154 is fixedly connected to the sliding plate 151. The contact rod 156 is set to be cylindrical.

[0053] The fixed rod 153 guides and limits the movement of the sliding plate 151 and the connecting frame 16. After the contact rod 156 is separated from the extrusion frame 144, the second elastic component 154 controls the sliding plate 151 and the vertical plate 17 to reset upward. At this time, the vertical plate 17 controls the movable frame 21 and the movable frame 24 to move upward through the movable plate 18. When the extrusion frame 144 approaches the contact rod 156, it controls the movable frame 21 to move downward.

[0054] Specifically, Figure 3-4 and Figure 8-9As shown, the sliding connection mechanism 20 includes a second guide block 201 slidably connected in the second guide groove 19, a third elastic component 202 is fixedly connected under the second guide block 201, the third elastic component 202 is fixedly connected in the second guide groove 19, a fourth elastic component 203 is fixedly connected on the second guide block 201, the fourth elastic component 203 is fixedly connected in the second guide groove 19, an extension rod 204 is fixedly connected to the side of the second guide block 201, and the other end of the extension rod 204 is fixedly connected to the movable frame 21.

[0055] The second guide groove 19 cooperates with the second guide block 201 to ensure that the movable frame 21 can slide vertically along the second guide groove 19. The elastic force of the third elastic component 202 and the fourth elastic component 203 acts on the second guide block 201 to keep the second guide block 201 relatively stable. The third elastic component 202 and the fourth elastic component 203 are pushed by the second guide block 201 to achieve buffering protection against vibration of the movable frame 21, thereby reducing the shaking and falling of food in the tableware caused by the vibration.

[0056] Specifically, Figure 5-6 and Figure 10-11 As shown, the clamping and limiting mechanism 27 includes a first piston cylinder 271 fixedly connected to the outside of the positioning block 26, a first piston plate 272 is slidably connected inside the first piston cylinder 271, a first sliding rod 273 is fixedly connected to the side of the first piston plate 272 close to the movable frame 21, and a clamping plate 274 is fixedly connected to one end of the first sliding rod 273 located outside the first piston cylinder 271, a first connecting sleeve 275 is provided on the outer sleeve of the first sliding rod 273, and the first connecting sleeve 275 is connected to the side of the first piston cylinder 271, the first piston cylinder 271 is connected to the intermediate tube 28, and a fifth elastic component 276 connected to the first piston plate 272 and the inner wall of the first piston cylinder 271 is provided on the outer sleeve of the first sliding rod 273.

[0057] The elastic force of the fifth elastic component 276 on the first piston plate 272 keeps the first piston plate 272 stable when the first piston cylinder 271 is at normal pressure, and keeps the clamping plate 274 separated from the movable frame 24. The increased air pressure in the first piston cylinder 271 controls the movement of the first piston plate 272. The first piston plate 272 controls the clamping plate 274 to move to contact with the movable frame 24 through the first sliding rod 273, so that the movable frame 24 remains stable and cannot rotate when the movable frame 24 is at the upper limit position.

[0058] Specifically, Figure 5-6 and Fig.10As shown, the extrusion control mechanism 29 includes a second piston cylinder 291 fixedly connected to the inner wall of the storage box 4, a second piston plate 292 is slidably connected in the second piston cylinder 291, a second sliding rod 293 is fixedly connected to the second piston plate 292, and a contact plate 294 is fixedly connected to the top end of the second sliding rod 293, and the contact plate 294 is arranged in the connecting groove 30.

[0059] The second sliding rod 293 is slidably connected to the outside with a second connecting sleeve 295, and the second connecting sleeve 295 is connected to the second piston cylinder 291 through a sixth elastic component 296 fixedly connected to the second piston plate 292 and the inner wall of the second piston cylinder 291 is disposed on the outer sleeve of the second sliding rod 293. The space in the second piston cylinder 291 located on the upper side of the second piston plate 292 is connected to the intermediate tube 28.

[0060] When the movable frame 24 pushes the dinner plate upward, the movable plate 18 moves upward, the contact plate 294 and the second sliding rod 293 move upward, the movable frame 24 drives the dinner plate and the food to move upward, and the elastic force of the sixth elastic component 296 automatically controls the second piston plate 292 to move upward. At this time, the gas in the upper space inside the second piston cylinder 291 is squeezed through the intermediate tube 28 into the first piston cylinder 271, controlling the air pressure change in the first piston cylinder 271.

[0061] Working principle, when using:

[0062] When the driving mechanism 2 operates according to the detection result of the detection component 9, the food delivery robot is controlled to move. If the ground is tilted, the bottom box 3 and the storage box 4 will be tilted during the movement of the driving mechanism 2. The movable frame 21 and the rotating shaft 23 rotate in the bearing 22. Due to the influence of the gravity at the bottom of the movable frame 24, the movable frame 24 is kept in a vertical state, so that the tableware in the placement slot 25 is kept in a horizontal state, and the food is prevented from tilting and spilling. If the storage box 4 is collided, the second guide block 201 slides in the second guide slot 19, and the third elastic component 202 and the fourth elastic component 203 are pushed by the second guide block 201 to achieve buffering protection against vibration of the movable frame 21, thereby reducing the shaking and falling of food in the tableware caused by vibration;

[0063] When it is necessary to take out the food, the electric hydraulic rod 10 extends to control the movement of the slide cover 6, and the slide cover 6 slides to the left to open. The elastic force of the first elastic component 142 on the first guide block 141 temporarily keeps the first guide block 141 in a stable and immobile state. The first elastic component 142 continues to extend. After the first elastic component 142 returns to its original length, the slide cover 6 continues to move and the first elastic component 142 pulls the squeezing frame 144 to reset. The second elastic component 154 controls the sliding plate 151 and the vertical plate 17 to reset upward. At this time, the vertical plate 17 controls the movable frame 21 and the movable frame 24 to move upward through the movable plate 18.

[0064] When the movable plate 18 moves upward, the contact plate 294 and the second sliding rod 293 move upward, and the movable frame 24 drives the dinner plate and the food to move upward. The gas in the upper space inside the second piston cylinder 291 is squeezed through the intermediate tube 28 into the first piston cylinder 271. The increased air pressure in the first piston cylinder 271 controls the movement of the first piston plate 272. The first piston plate 272 controls the clamping plate 274 through the first sliding rod 273 to move to contact with the movable frame 24, so that the movable frame 24 remains stable. After the sliding cover 6 moves to a fully open state, the electric hydraulic rod 10 stops working, and the food in the stable movable frame 24 can be removed.

[0065] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
