technical field

The utility model belongs to the technical field of meal delivery robots, in particular to a dining tray cover for a meal delivery robot.

Background technique

With the increasing quality of service in the catering industry, most people choose to dine out; for restaurants, many waiters need to be employed to deliver meals in order to meet the needs of customers. However, the ageing population at this stage has led to higher costs for hiring waiters. Moreover, during the peak meal period, manual meal delivery is prone to accidental collisions, resulting in accidents such as meals being overturned and personnel injuries, increasing the risk of meal delivery.

Existing mobile food delivery robots include trays for carrying objects to be transported. The trays are exposed to the air, have poor dust-proof effect, and are easily taken away by humans. Based on this, the patent document with publication number CN208529109U discloses a box-type mobile robot, including a control module, a robot body, a universal wheel, a driving wheel and a chassis, the chassis includes a first support plate, and the universal wheel and the driving wheel are connected with the chassis; The robot body includes a door body, a second support plate, and a storage structure that forms a storage space with the door body; the door body and the storage structure are respectively connected to the second support plate, and the second support plate and the first support plate pass through The first connector is connected. The robot body controls the rotation direction and rotation speed of the driving wheel through the control module to control the movement of the box-type mobile robot; the bottom surface of the storage structure is connected with the second support plate through the rotating structure, and the storage structure is closed with the door to form a closed storage space to avoid the storage space being exposed to the external environment, so as to prevent the items placed in the storage space from slipping to the ground or being destroyed or taken away by humans, which improves the safety of the robot to transport items. However, the storage structure of the box-type mobile robot has inconveniences when taking the dishes, for example, it is necessary to bend over to take the dishes.

Therefore, it is necessary to design a new dining tray cover for food delivery robots.

Detailed ways

In order to illustrate the embodiments of the present utility model more clearly, the specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, and for those of ordinary skill in the art, other drawings can also be obtained from these drawings without creative efforts. Obtain other implementations.

As shown in FIGS. 1-6 , the dish cover of the meal delivery robot according to the embodiment of the present invention includes a cover body 1 and a plate rack installed in the cover body 1 . There is a cover 11 for opening or closing the meal opening.

The plate rack includes three layers of plate holders 20 distributed along the height direction of the cover body and with preset spacing (the number of layers of the plate holders is not limited to three layers, but can also be two layers, four layers, five layers, six layers, etc.) And the foldable brackets 21 arranged between the adjacent plate holders; in addition, as shown in Figures 3 and 4, the plate holder also includes four guide columns 22 (the number of the guide columns is not limited to four, it can also be two 1, three, six, etc.), each plate seat is slidably fitted with the guide column; specifically, the plate seat 20 has a sliding sleeve 200 corresponding to the guiding column one-to-one, and the sliding sleeve 200 is slidably connected with the corresponding guiding column 22 to improve the The stability of the plate seat rising. A load-bearing seat 5 is fixed below the plate seat of each layer, so as to improve the structural strength of the plate seat.

As shown in FIG. 5 , in the original state, the foldable bracket 21 is in the unfolded state, and under the action of external force, the foldable bracket 21 moves to the folded state, as shown in FIG. 6 . Specifically, the foldable bracket 21 includes a first connecting piece 210 and a second connecting piece 211 that are hinged with each other, and the first connecting piece 210 and the second connecting piece 211 are respectively hinged with two adjacent tray seats, so that the foldable bracket 21 When switching from the original state to the folded state, the distance between the two adjacent dinner plates can be reduced in coordination, that is, the lower plate can be raised. Wherein, the number of the foldable brackets 21 disposed between two adjacent dinner plates can be designed according to actual requirements, for example: one, two, three, four and so on.

In order to realize the folding of the foldable brackets, the plate cover of the embodiment of the present invention further includes a driving mechanism, which is used to drive the lower plate seat to rise, so as to link the folding of each foldable bracket to raise the corresponding plate seat. Specifically, as shown in Figures 3 and 4, the drive mechanism includes a drive motor 3 and a rotating shaft 4, the drive motor 3 is used to drive the rotating shaft 4 to rotate, the rotating shaft 4 includes a threaded section 40 and a polished rod section 41, the threaded section 40 and the motor of the driving motor The shafts are connected so that the drive motor 3 drives the shaft 4 to rotate; the threaded section 40 penetrates each plate holder and its corresponding bearing seat to the top plate holder, so that the polished rod section 41 extends to the top of the cover. Wherein, each bearing seat 5 has a threaded hole matched with the threaded section of the rotating shaft 4; the bearing seat 5 is supported under its corresponding plate seat to realize linkage with the plate seat. The polished rod section 41 is used for accommodating the plate holder, and the height of the polished rod section 41 is smaller than the height of the foldable bracket 21 in the unfolded state. In addition, the height of the polished rod section can be determined according to the height and the number of layers of the tray holders, so that each tray holder can be stacked.

In addition, the upper surface of each plate seat is provided with a non-slip layer to prevent the plate placed on the plate seat from sliding and ensure the stability of the plate.

The plate holder is equipped with strain gauges for detecting plates. When the strain gauge detects the dishes and all the dishes are placed, the corresponding motor drives the drive cover to close the food intake, and the plate cover can be automatically closed; for example: when the food delivery robot reaches the delivery position, the food The plate cover can be opened automatically; after reaching the delivery position, the plate cover can be opened automatically, and it can be automatically closed after detecting that the tableware is taken out; when it is detected that all the plates are taken out, the plate cover is automatically closed. In addition, the solution for realizing automation of opening or closing the cover plate may also refer to the design similar to that of the electric door, and the specific reference may be made to the prior art, which will not be repeated here.

In order to keep the food in the plate in the cover warm, a heating wire is arranged in the cover.

In the meal tray cover of the meal delivery robot according to the embodiment of the present utility model, when the strain gauge detects that there is no plate in the top plate holder, the drive motor drives the rotating shaft to rotate, linking each plate holder to rise, and the top plate holder is covered by the top of the cover body. When the position is limited, the drive motor continues to drive, so that the foldable bracket between the top plate holder and its adjacent plate holder is switched from the original state to the folded state and is in the polished rod section, reducing the vacant space in the upper part and making the lower part. The plate seat is raised, making it easier for customers to take their meals. And so on, until the plate of the bottom plate holder is taken out.

The above only describes the preferred embodiments and principles of the present invention in detail. For those of ordinary skill in the art, according to the idea provided by the present invention, there will be changes in the specific implementation, and these changes will It should also be regarded as the protection scope of the present invention.
