[0036] When the food delivery robot delivers dishes, tea, tableware and other items to guests, some guests are more particular and pay special attention to food hygiene. In the distance between the food delivery robot and the guest's table, if the plate is open, there may be mosquitoes and dust in the restaurant. When there are many guests, there will also be pollution such as droplets, dust, and water. Some guests are more concerned about the privacy of their ordering and hope that the food can be delivered directly to the table in a shielded state, which is both hygienic and private. Moreover, during the food delivery process, the food delivery robot may stop suddenly, so the food may slip off the plate. In short, the open food delivery robot (without shielding the food) has a series of disadvantages.

[0037] In order to solve the above technical problems, the utility model proposes a meal plate dust cover and a meal delivery robot. The meal plate dust cover can be detachably connected to the meal delivery robot, so that the meal plate dust cover can be applied to the previous machine. Users who have purchased an open meal delivery robot can purchase and use the meal plate dust cover according to their needs. The newly produced meal delivery robot can be equipped with a meal plate dust cover, and users can choose to use it according to their needs. The meal plate dust cover 100 proposed by the utility model includes a guard plate assembly 1 and a door panel assembly 2. The guard plate assembly 1 and the door panel assembly 2 are both used to shield the meal plate assembly 200, and can shield the food on the meal plate assembly 200, which has the function of dustproof and anti-pollution. The door panel assembly 2 can rotate relative to the guard plate assembly 1, so that the door panel assembly 2 can be opened to expose the food. When the food is exposed, the door panel assembly 2 is in an open state, and when the food is blocked, the door panel assembly 2 is in a closed state. When the meal delivery robot arrives at the designated position, the door panel assembly 2 can be opened, the food can be taken out, and then the door panel assembly 2 can be closed.

[0038] The dining plate dust cover 100 provided in the embodiment of the present utility model is now described.

[0039] Please also read Figure 1 and Figure 2 The dish dust cover 100 is used to cover the circumference of the dish assembly 200. The dish assembly 200 is a part of the main structure of the meal delivery robot. The dish assembly 200 at least includes a dish body 3, which is used to carry food, tableware, tea, etc. Since the dish body 3 needs to carry the above-mentioned various items, the dish body 3 is placed horizontally, and the circumference of the dish assembly 200 can be understood as the circumference along the edge of the dish body 3.

[0040] The dining plate dust cover 100 includes a guard plate assembly 1 and a door panel assembly 2 rotatably connected to the guard plate assembly 1 , wherein the guard plate assembly 1 is used to be detachably connected to the dining plate assembly 200 , and the guard plate assembly 1 and the door panel assembly 2 enclose a shielding space for shielding the dining plate assembly 200 .

[0041] The guard plate assembly 1 is detachably connected to the dining tray assembly 200, and the dining tray assembly 200 can move with the food delivery robot. In other words, the guard plate assembly 1 can be connected to the dining tray assembly 200, and can also be removed from the dining tray assembly 200. Since the door panel assembly 2 needs to rotate relative to the guard plate assembly 1, the door panel assembly 2 is not directly connected to the dining tray assembly 200. In this way, when the guard plate assembly 1 is connected to the dining tray assembly 200, the entire dining tray dust cover 100 is connected to the dining tray assembly 200, and when the guard plate assembly 1 is removed from the dining tray assembly 200, the entire dining tray dust cover 100 is removed from the dining tray assembly 200.

[0042] The guard plate assembly 1 and the door panel assembly 2 are both arranged around the dining tray assembly 200, and the guard plate assembly 1 and the door panel assembly 2 form a shielding structure for shielding the dining tray assembly 200, so that the circumference of the dining tray assembly 200 is shielded by the guard plate assembly 1 and the door panel assembly 2, and the food will not be exposed.

[0043] The door panel assembly 2 is rotatably connected to the guard panel assembly 1, so that the door panel assembly 2 can be switched between an open state and a closed state. When it is necessary to take out or place food, the door panel assembly 2 can be rotated to an open state, and the door panel assembly 2 is in a closed state while the food is being delivered by the food delivery robot. The door panel assembly 2 is rotatably connected to the guard panel assembly 1, so that the door panel assembly 2 can be operated with one hand, providing convenience for service personnel.

[0044] The meal tray dust cover 100 in the above embodiment includes a guard plate assembly 1 and a door panel assembly 2. The guard plate assembly 1 is detachably connected to the meal tray assembly 200, and the door panel assembly 2 is rotatably connected to the guard plate assembly 1. The guard plate assembly 1 and the door panel assembly 2 can jointly shield the meal tray assembly 200 to prevent the food placed on the meal tray assembly 200 from being exposed, and can play the role of dustproof, mosquito-proof, etc., and can also protect the privacy of customers ordering meals. After the meal delivery robot arrives at the destination, the door panel assembly 2 can be opened to take out the food. Moreover, the guard plate assembly 1 is detachably connected to the meal tray assembly 200, so that the meal tray dust cover 100 can be applied to the existing open meal delivery robot, and the user can purchase and install the meal tray dust cover 100 according to the needs, so that the application of the dust cover is more extensive.

[0045] In some embodiments of the present invention, please refer to Figures 1 to 3 The guard plate assembly 1 includes a left guard plate 11 and a right guard plate 12.

[0046] The guard plate assembly 1 includes at least two guard plates, namely a left guard plate 11 and a right guard plate 12. The left guard plate 11 and the right guard plate 12 are arranged opposite to each other and can be detachably connected to the dining tray assembly 200. Specifically, the left guard plate 11 is detachably connected to one side of the dining tray assembly 200 and is used to shield the side of the dining tray assembly 200. The right guard plate 12 is detachably connected to the other side of the dining tray assembly 200 and is used to shield the side of the dining tray assembly 200. The dining tray assembly 200 includes a back plate 4 and a dining tray body 3. The dining tray body 3 is horizontally arranged to carry food. The guard plate assembly 1 shields the circumference of the dining tray assembly 200. It can be understood that the guard plate assembly 1 shields the circumference of the dining tray body 3. Since the dining plate body 3 is connected to the back plate 4, the back plate 4 blocks part of the circumferential space of the dining plate body 3, and the remaining circumferential space is blocked by the left guard plate 11, the right guard plate 12 and the door panel assembly 2, so that each position of the circumference of the dining plate body 3 is blocked.

[0047] By setting the guard plate assembly 1 as a left guard plate 11 and a right guard plate 12, the two relatively exposed side surfaces of the dining plate assembly 200 can be respectively shielded, so that both of the relatively exposed side surfaces can be shielded, and the left guard plate 11 and the right guard plate 12 are installed separately, and the space requirements and precision requirements for the installation are also relatively low, which is more convenient for users to purchase and install later.

[0048] In some embodiments, the back plate 4 is vertically or nearly vertically arranged, and the back plate 4 can not only serve as a mounting structure for the dining tray body 3, but also serve as a main structural component of the food delivery robot in the vertical direction.

[0049] In some embodiments, there are multiple dining tray bodies 3, and the multiple dining tray bodies 3 are arranged in sequence and spaced apart in the vertical direction to form multiple placement spaces for placing food.

[0050] In some embodiments, the door panel assembly 2 is disposed between the left guard plate 11 and the right guard plate 12. When the door panel assembly 2 is opened, the space between the left guard plate 11 and the right guard plate 12 is exposed, which is convenient for taking and placing food. In this embodiment, the left guard plate 11 and the right guard plate 12 are disposed opposite each other, and the door panel assembly 2 can be disposed opposite the back panel 4.

[0051] In some embodiments, the door panel assembly 2 includes a door body, one side of which is rotatably connected to one of the left guard plate 11 and the right guard plate 12, and the other side of the door body can be close to the other of the left guard plate 11 and the right guard plate 12. In other words, the door panel assembly 2 is a single-opening door structure.

[0052] In some embodiments of the present invention, please refer to Figure 1 and Figure 2 The door panel assembly 2 includes a left door panel 21 and a right door panel 22 , the left door panel 21 is rotatably connected to the left guard plate 11 , and the right door panel 22 is rotatably connected to the right door panel 22 .

[0053] It can be understood that the door panel assembly 2 includes two door panels, namely a left door panel 21 and a right door panel 22. The left door panel 21 is rotatably connected to the left guard plate 11, and the right door panel 22 is rotatably connected to the right guard plate 12. In other words, the door panel assembly 2 is a double-door structure. When installing the dining plate dust cover 100, the left door panel 21 and the left guard plate 11 are an integral component, and the right door panel 22 and the right guard plate 12 are an integral component. The two integral components can be installed separately, and the installation is relatively simple and convenient.

[0054] By configuring the door panel assembly 2 as a left door panel 21 and a right door panel 22, firstly, the left door panel 21 or the right door panel 22 can be selectively opened according to the requirements of taking and placing, and secondly, the space that can be opened for the dining plate dust cover 100 can be larger, making it more convenient to take and place food.

[0055] In some embodiments, the left door panel 21 and the left guard plate 11 are rotatably connected via a hinge 24 , and the right door panel 22 and the right guard plate 12 are rotatably connected via a hinge 24 .

[0056] In some embodiments of the present invention, please refer to Figure 2 A first magnetic component 251 is provided on the left door panel 21, and a second magnetic component 252 is provided on the right door panel 22. When the left door panel 21 and the right door panel 22 cover the dining plate body 3, the first magnetic component 251 and the second magnetic component 252 are attracted to each other.

[0057] The left door panel 21 and the right door panel 22 are respectively provided with a first magnetic component 251 and a second magnetic component 252. When the left door panel 21 and the right door panel 22 cover the dining plate body 3, that is, when the door panel assembly 2 is in a closed state, the first magnetic component 251 and the second magnetic component 252 are attracted to each other, so that the adjacent two sides of the left door panel 21 and the right door panel 22 are attracted to each other, so that the door panel assembly 2 can remain in a closed state.

[0058] By providing the first magnetic member 251 and the second magnetic member 252, the door panel assembly 2 can be kept in a closed state under the action of the magnetic attraction of the two, thereby preventing the left door panel 21 and the right door panel 22 from rotating on their own while moving with the food delivery robot.

[0059] In some embodiments, one of the first magnetic attraction member 251 and the second magnetic attraction member 252 is a magnet, and the other is a magnetic attraction member, such as an iron member.
