Detailed Implementation Manner

[0017] In order to more clearly understand the above-mentioned objects, features, and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0018] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0019] Embodiment, according to Figures 1-9 , as Figures 1-2 shown, a tipping-proof food delivery robot provided by an embodiment of the present invention includes a main body mechanism 100, and a plurality of symmetrically distributed shock absorption mechanisms 300 are installed on the main body mechanism 100. A pallet mechanism 200 is installed on each of the symmetric shock absorption mechanisms 300. The pallet mechanism 200 can adjust the area for carrying food, and the pallet mechanism 200 can lock and position the shock absorption mechanism 300; as Figure 6 shown, the shock absorption mechanism 300 includes a bearing plate 301. Chutes 305 are penetrated and opened on both sides of the bearing plate 301. Lower support blocks 306 are fixedly connected to the four corners of the lower surface of the bearing plate 301. A mounting rod 307 is movably installed in each of the lower support blocks 306. A fixed sheet metal 302 is fixedly connected to one end of each mounting rod 307. A support spring 308 is sleeved and installed on each mounting rod 307. The bearing plate 301 can horizontally move along the mounting rod 307 through the lower support block 306. Among them, the support spring 308 can support and limit the lower support block 306, so as to stably support the bearing plate 301 on the mounting rod 307; as Figure 7As shown, the pallet mechanism 200 includes a pallet main body 202. The pallet main body 202 is arranged in a U shape. On both sides of the top end of the pallet main body 202, side slide rails 201 are fixedly connected. Two extension pallets 203 are slidably installed in each of the two side slide rails 201. Both of the two extension pallets 203 are located above the pallet main body 202. Side extension rods 204 are fixedly connected to the surfaces of both sides of the pallet main body 202. The two extension pallets 203 move along the side slide rails 201 to both sides, and the areas of the two extension pallets 203 and the pallet main body 202 can be adjusted, so as to be applicable to transporting more food items and improve the food delivery efficiency of the food delivery robot.

[0020] As Figures 3-5 shown, the main body mechanism 100 includes an assembly base 101. A mobile device 102 is installed on the lower surface of the assembly base 101. Support connecting rods 103 are fixedly connected to the four corners of the upper surface of the assembly base 101. The upper ends of the support connecting rods 103 are fixedly connected to a top plate 104. A display screen 105 is fixedly connected to the upper surface of the top plate 104. The display screen 105 can display food item information or guide guests. Each fixed sheet metal 302 is fixedly connected to the outer side wall of the support connecting rod 103. Side support plates 304 are fixedly connected to both sides of the lower surface of the bearing plate 301. Each fixed sheet metal 302 is fixedly connected to the outer side wall of the side support plate 304. One end of the inner side of each mounting rod 307 is rotatably installed with a restraint rod 309. A connecting bottom block 310 is rotatably installed between the two restraint rods 309. Each connecting bottom block 310 is fixedly connected to the lower end of the side extension rod 204. Each side extension rod 204 is movably installed through the bearing plate 301. When the food delivery robot jolts during movement, the pallet main body 202 and the side extension rods 204 will move up and down along the bearing plate 301. The connecting bottom block 310 can support the movement of the side extension rods 204, and the vibration force will be conducted to the support springs 308 through the mounting rods 307, so as to achieve a buffering and shock-absorbing effect on the bearing plate 301. A slide rail 303 is fixedly connected to the lower surface of the bearing plate 301 near one side of the chute 305.

[0021] As Figures 7-9As shown in the figure, a connecting sheet metal 212 is fixedly connected to the edge of the lower surface of each of the extension pallets 203. A fixed connecting rod 211 is fixedly connected to the inner side of each of the connecting sheet metals 212. A limiting sheet metal 210 is movably installed on each of the fixed connecting rods 211. Each of the limiting sheet metals 210 is fixedly connected to the lower surface of the side extension rod 204. On both sides of one end of each of the fixed connecting rods 211, a transmission connecting rod 209 is rotatably installed. Below the two transmission connecting rods 209, an installation bracket 207 is rotatably installed. The installation bracket 207 is slidably installed in the chute 305. The two installation brackets 207 and the two fixed connecting rods 211 are connected by four transmission connecting rods 209. When the two extension pallets 203 move outward, the distance between the two installation brackets 207 will be shortened. On the contrary, when the two extension pallets 203 contract inward, the distance between the two installation brackets 207 will increase. The two installation brackets 207 are both meshed with a driving lead screw 208. A double-shaft motor 206 output shaft is fixedly connected between the two driving lead screws 208. The double-shaft motor 206 is fixedly connected to the middle of the upper surface of the bearing plate 301. The double-shaft motor 206 drives the driving lead screw 208 to rotate, and the driving lead screw 208 drives the installation bracket 207 to move horizontally along the chute 305. A push rod 214 is rotatably installed on the lower surface of each of the installation brackets 207. The lower end of the push rod 214 is rotatably installed with a turntable 213. The center of the upper surface of the turntable 213 is fixedly connected with a central shaft 215. The top end of the central shaft 215 is rotatably installed on the lower surface of the bearing plate 301. When the two installation brackets 207 move, by adjusting the distance between the two installation brackets 207, the turntable 213 can be driven to rotate around the central shaft 215. On the edge of both sides of the upper surface of the turntable 213, a restraint plate 216 is also rotatably installed. One end of each of the restraint plates 216 is rotatably installed with a slider 217. Each of the sliders 217 is slidably installed in the slide rail 303. A plug rod 218 is fixedly connected to the outer side wall of each of the sliders 217. Each of the plug rods 218 is inserted and connected in the limit groove 205. When the turntable 213 rotates, the two extension pallets 203 will extend to both sides with the pallet body 202 as the center. When the food delivery robot carries more food items, the food items will be affected by inertia and may tip over. The turntable 213 can push the slider 217 to move horizontally along the slide rail 303 through the restraint plate 216. Subsequently, the plug rod 218 will be inserted into the limit groove 205 of the side extension rod 204, and the side extension rod 204 will not rise or fall, thereby realizing the locking and positioning of the bearing plate 301, so that the food delivery robot achieves the effect of preventing tipping.

[0022] The working principle of the present invention is as follows: This food delivery robot can be adjusted according to the number of food deliveries. When the number of food deliveries is small, the dual-axis motor 206 is started to drive the driving lead screw 208 to rotate. The driving lead screw 208 drives the two mounting brackets 207 to move horizontally along the chute 305, increasing the distance between the two mounting brackets 207. Further, the extended pallet 203 will move above the pallet main body 202. When the food delivery robot jolts during movement, the pallet main body 202 and the side extension rod 204 will move up and down along the bearing plate 301. The connecting bottom block 310 can support the movement of the side extension rod 204, and the vibration force will be transmitted to the support spring 308 through the mounting rod 307, thereby achieving a buffering and shock-absorbing effect on the bearing plate 301. When the number of food deliveries is large, the dual-axis motor 206 drives the two mounting brackets 207 to shorten the distance. Through the transmission of the transmission connecting rod 209, the distance between the two fixed connecting rods 211 is increased. Subsequently, the fixed connecting rod 211 will drive the extended pallet 203 to move horizontally along the side slide rail 201, and the extended pallet 203 unfolds with the pallet main body 202 as the center. Then, the mounting bracket 207 drives the turntable 213 to rotate around the central axis 215 through the lower surface push rod 214. The turntable 213 can push the slider 217 to move horizontally along the slide rail 303 through the restraint plate 216. Subsequently, the insertion rod 218 will be inserted into the limit groove 205 of the side extension rod 204, and the side extension rod 204 will not move up and down, thereby achieving the locking and positioning of the bearing plate 301 and enabling the food delivery robot to achieve the effect of preventing tipping.

[0023] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
