Description

Modular frame device for food delivery robot

The invention relates to a frame device, in particular to a modular frame device of a food delivery robot.

With the aging of most developed countries and the continuous advancement of robot-related technologies, the trend of replacing old labor jobs with robots is unstoppable. This trend has also blown to the fields of home care, restaurant and shopping mall automation. A food delivery robot that can automatically deliver meals in a specific area, this type of food delivery robot usually transports the meals placed on the bracket through a fixed bracket, that is, each food delivery robot is set with a fixed height , fixed width and fixed number of layers of brackets, but this kind of fixed brackets cannot be adjusted according to the type of meal, the size of the application area, and the service content, for example, the bracket layer cannot be lowered under the condition of low load capacity number to reduce collisions in narrow environments, or conversely increase the number of bracket layers to increase the carrying capacity, which is not conducive to modularization and low versatility. In addition, the position of the center of gravity of the general bracket is not specially designed, which makes it easy for the food delivery robot to lean forward due to the unstable center of gravity when moving, which will cause the situation of overturning.

Therefore, the object of the present invention is to provide a stable and freely assembled frame device.

Therefore, the modular frame device of the meal delivery robot of the present invention is suitable for being arranged on a meal delivery robot, and the modular frame device includes a bottom unit fixed on the meal delivery robot, and a plurality of units detachably arranged on the meal delivery robot. A seat above the bottom unit, a plurality of connecting pieces detachably embedded in the seat, and at least one receiving unit. The bottom unit includes two bases respectively arranged on the left and right sides of the meal delivery robot, and two underframes respectively inserted on the bases. Each chassis has a lower inserting portion inserted on the corresponding base, a plurality of obliquely curved ribs extending upward and backward from the lower inserting portion, and a plurality of obliquely curved ribs extending upwardly from the obliquely curved ribs respectively. supporting ribs, and an upper inserting portion connected to the supporting ribs and protruding upwards. The center of gravity of the upper socket part is located relatively behind the center of gravity of the lower socket part. The at least one receiving unit includes a supporting plate extending along the horizontal direction and having two connecting pieces at the same height at the left and right ends detachably connected respectively.

The effect of the present invention is that: the present invention adopts a modular assembly design, so users can freely assemble a matching number of these sockets and these connecting pieces according to conditions such as the loading capacity and the size of the site each time, so as to connect all The number of layers of carrier plates is required. When the carrying capacity is large and the space permits, more layers of carrier plates can be assembled to increase the number of meals that can be placed. When the carrying capacity is small, fewer layers of carrier plates can be assembled. Carrier (or even just one layer) to reduce the waste of space. In addition, through the design of these obliquely curved ribs bent backwards, the center of gravity of the seat assembled on the upper insertion parts is shifted backwards, and at the same time, the center of gravity of the entire modular frame device is moved backwards. When the food delivery robot moves, it can generate a counter moment capable of resisting the moment of inertia, which solves the problem of the food delivery robot tilting forward and improves the stability of the food delivery robot when it is moving.

Referring to Fig. 2, Fig. 5, and Fig. 9, these reinforcing pieces 6 are respectively embedded in the two lowermost seats 3, and each reinforcing piece 6 includes a wall-mounted part that is clamped to the corresponding seat 3 31 between the main body portion 61, an upper buckle portion 62 connected to the upper end of the main body portion 61 and extending inwardly between the pillar portions 42 of the corresponding bracket 4, and a buckle portion 62 connected to the lower end of the main body portion 61 and inwardly. The lower buckle portion 63 extends between the support ribs 223 corresponding to the base frame 22 . The reinforcing member 6 is disposed on the seat 3 and fastened to the bracket 4 and the base frame 22 so that the bracket 4 and the base frame 22 are not easy to shake relative to each other and can improve stability.

Referring to Fig. 2, Fig. 10, and Fig. 11, each receiving unit 7 includes a bearing plate 71 extending in the horizontal direction and the left and right ends are respectively detachably connected to two connectors 5 at the same height, and two through The supporting plate 71 and the fixing pins 72 of the connecting parts 5 , a non-slip pad 73 fixed on the supporting plate 71 , and a plurality of trays 74 arranged on the supporting plate 71 . One end of the supporting plate 71 is inserted into the socket 521 of the extension plate portion 52 of the corresponding connecting piece 5, and the fixing pin 72 passes through the positioning opening 522 and the supporting plate 71 to fix the supporting plate 71 on on the connector 5. Each tray 74 has a disc body portion 741 placed on the supporting plate 71, a plurality of positioning claws 742 extending radially outward from the disc body portion 741 and bent upward to hook up, and a set of positioning claws 742 arranged on the tray. The magnetic attraction part 743 of the body part 741 . The non-slip pad 73 can make the meals placed on it not easy to slide. In addition, the meals can be placed on the trays 74, and the position of the meals can be limited by the positioning claws 742, and the magnetic attraction can 743 further absorbs the metal dinner plate to increase the fixing effect, thereby improving the stability of the meal during transportation.

Referring again to Fig. 1 and Fig. 2, the main advantage of this embodiment is that it allows the user to freely assemble the components according to actual needs, so in addition to the aforementioned configuration methods, there are also other different assembly methods due to different types of robots. For example, the two lowermost seats 3 in this case are just on both sides of the meal delivery robot 1, so they will be blocked by the body of the meal delivery robot 1 and cannot be equipped with a carrier plate 71, but when the body height is lower than the When the food delivery robot 1 of the bottom unit 2 is on the ground, the reinforcing parts 6 can be replaced with the connecting parts 5 to add a layer of bearing plate 71 . In addition, the number of the seats 3 can be increased or decreased to increase or decrease the number of the bearing plates 71, so that modular frame devices of different heights can be assembled according to the required carrying capacity or walking space. , and the trays 74 or the anti-slip pads 73 that can improve the stability can be installed according to the type of meals to be carried. The versatility is extremely high, and the modular and detachable design can also reduce the difficulty of maintenance and mold opening cost.

In summary, the present invention can be freely assembled into different forms according to the needs of users, so that it can be customized and adjusted for different application scenarios, has high versatility and is also convenient for maintenance; in addition, through each obliquely curved rib The top of 222 is designed to be offset backwards compared to the bottom, so that the center of gravity of the entire modular frame device moves backwards, so that when the food delivery robot 1 moves, it can generate a moment in the opposite direction that can resist the moment of inertia, and solve the problem of delivery. The problem of the forward inclination of the meal robot 1 improves the stability of the meal delivery robot 1 when it travels, so the purpose of the present invention can indeed be achieved.
