[0037] Please refer to Figures 1 to 3. An embodiment of the present application provides a tray device, including a base 100, a weighing module 200, a tray body 300 and a dustproof frame 400. The weighing module 200 is arranged on the base 100; the tray body 300 is arranged on the weighing module 200; the dustproof frame 400 is arranged between the tray body 300 and the base 100. The tray body 300, the dustproof frame 400 and the base 100 are arranged to form a sealed cavity, and the weighing module 200 is located in the sealed cavity.

[0038] The above-mentioned tray device, the tray body 300 is arranged on the weighing module 200 and is used to carry the items to be delivered. By setting a dustproof frame 400 between the base 100 and the tray body 300 to form a sealed cavity, and setting the weighing module 200 in the sealed cavity, the dustproof frame 400 can play a certain role in isolating external dust; compared with traditional technology, the above-mentioned tray device can effectively prevent external dust or foreign objects from entering the weighing module 200, ensure the weighing sensitivity of the weighing module 200, enable the weighing module 200 to more accurately obtain the weight of the items to be delivered, and improve the operation reliability of the delivery robot.

[0039] Furthermore, the tray body 300 and the base 100 are spaced apart and have a gap, and the dustproof frame 400 is located in the gap and surrounds the weighing module 200 in the sealed cavity. When the tray body 300 is loaded with items to be delivered, the tray body 300 will press the weighing module 200 due to the gravity of the items to be delivered. During this process, the weighing module 200 will be deformed to a certain extent due to the load of the items on the tray body 300. At this time, the tray body 300 will have a certain displacement, and the gap between the tray body 300 and the base 100 is to reserve space for the tray body 300 to move, so that the weighing module 200 can accurately obtain the weight of the items to be delivered. In this embodiment, the dustproof frame 400 located in the gap can play a certain role in isolating dust and foreign objects from the outside, so as to prevent dust or foreign objects from entering the weighing module 200 and affecting the sensitivity of the weighing module 200.

[0040] As a supplementary explanation, the present application can also sense whether there are items to be delivered on the tray 300 by obtaining the weight on the tray 300, and then decide whether the delivery robot should set out for delivery or return.

[0041] Referring to Fig. 1, in one embodiment, the tray device further comprises a protective pad 510, which is disposed on the tray body 300. By providing the protective pad 510, when the tray needs to transport food with soup, the soup can be prevented from spilling onto the tray body 300 during the delivery process, thereby keeping the tray body 300 clean.

[0042] Specifically, the protective pad 510 is detachably connected to the dish body 300. In this way, when soup or the like on the food is spilled onto the protective pad 510, the protective pad 510 can be disassembled and cleaned.

[0043] Furthermore, at least one side of the protection pad 510 is provided with anti-skid patterns. By providing anti-skid patterns on the side of the protection pad away from the tray body 300, it is possible to prevent objects from sliding on the protection pad and falling off; by providing anti-skid patterns on the side of the protection pad 510 close to the tray body 300, it is also possible to prevent the protection pad 510 from moving on the tray body.

[0044] Furthermore, a barrier is provided along the circumference of the protection mat 510. The barrier can further prevent the items to be delivered from falling off the protection mat 510.

[0045] Furthermore, a protective cover 520 is provided around the protective pad 510, and the protective cover 520 extends in a direction away from the object to be delivered and can cover the gap. This arrangement can further prevent dust or foreign objects from entering the weighing module 200 through the gap and affecting the weighing accuracy of the weighing module 200.

[0046] Furthermore, there is a gap between the protective cover 520 and the base to prevent friction between the protective cover 520 and the base from affecting the weighing result.

[0047] Specifically, the interval between the protective cover 520 and the base is 2 mm.

[0048] Specifically, in order to prevent the protective cover 520 and the tray 300 from generating friction with the body of the robot, the side where the protective cover 520 and the tray 300 are connected to the body should be made as small as possible.

[0049] Optionally, the material of the protection pad 510 and the protection cover 520 can be silicone, or leather, etc., which is not specifically limited here.

[0050] In one embodiment, the dustproof frame 400 is disposed on the base 100 and is spaced apart from the plate 300 to form a first avoidance gap. This arrangement can prevent dust and other foreign objects from entering the weighing module 200 while also reserving space for the plate 300 to move, so that the weighing module 200 can more accurately obtain the weight of the items to be delivered.

[0051] For explanation, the width of the first avoidance gap should be smaller than the diameter of foreign objects such as dust from the outside. This can not only prevent foreign objects such as dust from entering the weighing module 200, but also reserve space for the pan body 300 to move.

[0052] Specifically, the width of the first avoidance gap is between 0.8 mm and 1.1 mm.

[0053] In another embodiment, the dustproof frame 400 is disposed on the tray body 300 and is spaced apart from the base 100 to form a second avoidance gap. Similar to the previous embodiment, the second avoidance gap in this embodiment can also reserve space for the tray body 300 to move while preventing dust, and accurately obtain the weight of the items to be delivered.

[0054] In other embodiments, the dustproof frame 400 is made of elastic material, the first surface of the dustproof frame 400 in the thickness direction is sealed against the tray body 300, and the second surface of the dustproof frame 400 in the thickness direction is sealed against the base 100. In this embodiment, since the dustproof frame 400 is made of elastic material, when the tray body 300 moves under the gravity of the items to be delivered, the dustproof frame 400 will be deformed in the thickness direction to allow the tray body 300 to move, so that the weighing module 200 can more accurately obtain the weight of the items to be delivered. At the same time, since the first surface and the second surface are sealed against the tray body 300 and the base 400 respectively, the sealing performance of the tray device can be further improved.

[0055] For explanation, the thickness direction in the above embodiments refers to the direction from the base 100 toward the tray body 300 .

[0056] Please refer to Figures 2 to 3. In one embodiment, the weighing module 200 includes a weighing sensor 220, a first support bar 241, a second support bar 242 and a mounting rod 250. The weighing sensor 220 is arranged on the base 100, the mounting rod 250 is arranged on the weighing part 222 and is located in the sealed cavity, the first support bar 241 and the second support bar 242 are respectively arranged at opposite ends of the mounting rod 250, and the first support bar 241 and the second support bar 242 are both abutted against the disk body 300.

[0057] The weight of the items to be delivered on the tray body 300 can be transferred to the mounting rod 250 through the first support bar 241 and the second support bar 242, and the load on the mounting rod 250 is transferred to the weighing sensor 220 to achieve weighing. In this way, not only can the tray body 300 be effectively supported and the weight of the items to be delivered be dispersed to prevent damage to the tray device, but the weight of the items to be delivered on the tray body 300 can also be more evenly transferred to the weighing sensor 220, thereby improving the weighing accuracy.

[0058] Furthermore, the first support bar 241 and the second support bar 242 are respectively arranged at opposite ends of the mounting rod 250 to form an I-shaped support structure, and the disk body 300 is supported by the I-shaped support structure, so that the weight of the heavy object on the disk body 300 is more evenly transferred to the weighing sensor 220.

[0059] Please refer to Figure 3. In one embodiment, the middle part of the mounting rod 250 is connected to the weighing sensor 220, and the connection position between the mounting rod 250 and the weighing sensor 220 is located in the middle part of the disk body 300, so that the weight of the heavy object on the disk body 300 directly acts on the weighing sensor 220 through the middle part of the mounting rod 250, so that the weight measured by the weighing sensor 220 is more accurate.

[0060] Please refer to Figures 2 and 3. In one embodiment, the dustproof frame 400 includes a side frame body 410 and a connecting piece 420. The side frame body 410 and the connecting piece 420 are each provided with at least two and correspond to each other. The side frame bodies 410 and the connecting pieces 420 are alternately arranged in a circumferential direction and connected end to end.

[0061] At least two side frames 410 are connected end to end through a connector 420 and surround the weighing module 200 in the middle, thereby preventing dust or foreign objects from entering the weighing module 200. The connector 420 can reinforce and limit the side frame 410 to prevent the side frame 410 from moving and being damaged.

[0062] For explanation, please refer to FIG. 3 . In the above embodiment, the side frame bodies 410 and the connecting members 420 are alternately arranged and connected end to end, which means that one end of one side frame body 410 is connected to one end of another side frame body 410 via the connecting member 420, and one end of the other side frame body 410 is connected to the other side frame body 410 via the connecting member 420, and so on. The last side frame body 410 is connected to one end of the first side frame body 410 via the last connecting member 420 to enclose and form a dustproof frame 400.

[0063] It can be understood that when the number of the side frame bodies 410 and the number of the connecting members 420 are both two, the shape of the side frame bodies 410 extends along a curve so that the two side frame bodies 410 can be connected end to end through the two connecting members 420; when the number of the side frame bodies 410 and the number of the connecting members 420 are both at least three, the shape of the side frame bodies 410 can extend along a curve or along a straight line as shown in FIG. 3, as long as it can be enclosed to form a dustproof frame 400.

[0064] Specifically, the side frame body 410 is made of foam, which has a light weight, low cost, and good dustproof effect.

[0065] Please refer to Figures 3 and 4. In one embodiment, the weighing module 200 includes a fixing base 210 and a weighing sensor 220. The fixing base 210 is disposed on the base 100 and has a connected inner cavity 211 and an opening. The weighing sensor 220 is disposed in the inner cavity 211, and the disk body 300 abuts against the weighing sensor 220 through the opening.

[0066] The fixing seat 210 is arranged on the base 100, and the weighing sensor 220 is arranged in the inner cavity 211 of the fixing seat 210 and abutted against the disk body 300 through the opening. In this way, it can ensure the weighing effect while playing a certain protective role for the weighing sensor 220. In addition, the fixing seat 210 can have a certain isolation effect on dust or foreign objects, further preventing dust or foreign objects from entering the weighing sensor 220 and affecting the weighing accuracy of the weighing sensor 220.

[0067] Specifically, the opening of the fixing seat 210 is disposed toward the disc body 300 to facilitate the connection between the disc body 300 and the weighing sensor 220 .

[0068] Please refer to Figures 2 to 4. In one embodiment, the weighing module 200 also includes an assembly portion 230, which is disposed on the fixing seat 210 and arranged around the outer periphery of the opening. The base 100 is provided with an installation opening 110, the fixing seat 210 is penetrated through the installation opening 110, and the assembly portion 230 is connected to the outer periphery of the installation opening 110.

[0069] The assembly portion 230 is arranged around the outer periphery of the opening of the fixing seat 210. The fixing seat 210 is inserted into the installation opening 110 and is connected to the outer periphery of the installation opening 110 through the assembly portion 230 to achieve the connection between the fixing seat 210 and the base 100. With this arrangement, the fixing seat 210 can be inserted as a whole into the installation opening 110 and connected to the base 100, making the overall structure more compact and reducing the installation space required for the tray device.

[0070] Specifically, the assembly portion 230 and the outer periphery of the installation opening 110 of the fixing seat 210 are connected to each other by bolts.

[0071] In one embodiment, the assembly portion 230 is provided with a positioning protrusion, and the outer periphery of the installation opening 110 is provided with a positioning hole, and the positioning protrusion and the positioning hole are positioned and matched with each other.

[0072] By means of the mutual positioning cooperation between the positioning protrusion and the positioning hole, the positioning cooperation between the fixing seat 210 and the base 100 is achieved, so that the fixing seat 210 can be correctly installed in the preset position during installation, thereby improving the consistency and accuracy of the overall tray device during assembly; in addition, the connection reliability between the fixing seat 210 and the base 100 can also be improved.

[0073] Furthermore, since the disk body 300 is connected to the weighing sensor 220 in the inner cavity 211 of the fixing seat 210, by setting the cooperation between the positioning protrusion and the positioning hole, the disk body 300 and the base 100 can also maintain assembly consistency during assembly, thereby improving the overall installation accuracy and reliability of the device.

[0074] In one embodiment, at least two positioning protrusions are provided and are spaced apart along the circumference of the assembly portion 230, and at least two positioning holes are provided and are arranged one-to-one with the positioning protrusions. By providing at least two positioning protrusions and positioning holes, the consistency and accuracy of the tray device as a whole during assembly can be further improved, and the connection reliability between the fixing seat 210 and the base 100 can also be further improved.

[0075] Please refer to Figures 4 and 5. In one embodiment, the bottom wall of the inner cavity 211 has an installation area 212 and an avoidance area 213. The avoidance area 213 is provided with an avoidance groove 214. The weighing sensor 220 includes a mounting portion 221 and a weighing portion 222. The mounting portion 221 is disposed in the installation area 212. One side of the weighing portion 222 is connected to the disk body 300, and the other side of the weighing portion 222 is disposed toward the avoidance groove 214.

[0076] The mounting portion 221 of the weighing sensor 220 is arranged in the mounting area 212 of the bottom wall. One side of the weighing portion 222 of the weighing sensor 220 is connected to the tray body 300, and the other side is arranged toward the avoidance groove 214. When there are items to be delivered on the tray body 300, the load of the tray body 300 will be transmitted to the weighing portion 222 of the weighing sensor 220. At this time, the weighing portion 222 will deform toward the side facing the avoidance groove 214, and the weight is measured by the deformation of the weighing portion 222; if the weight of the items to be delivered on the tray body 300 is too large, the deformation of the weighing portion 222 will increase or even break; by setting the side of the weighing portion 222 away from the tray body 300 toward the avoidance groove 214, the maximum deformation of the weighing portion 222 can be limited while allowing the weighing portion 222 to deform, thereby preventing the weighing sensor 220 from being damaged and improving the safety and life of the tray device.

[0077] Specifically, the depth of the avoidance groove 214 is between 1.3 mm and 1.8 mm to meet the requirement that the maximum weight of the items to be delivered is 10 kg.

[0078] Furthermore, the avoidance groove 214 is manufactured by using a glue removal process.

[0079] In one embodiment, the weighing portion 222 is connected to the center of the tray 300 to achieve accurate weighing.

[0080] Please refer to Figures 4 and 5. In one embodiment, the inner cavity 211 has a side wall and a rear wall. The installation area 212 is provided with a first positioning block 215 and a second positioning block 216. The first positioning block 215 is used to abut against the side of the installation portion 221 facing the side wall, and the second positioning block 216 is used to abut against the side of the installation portion 221 facing the rear wall.

[0081] The first positioning block 215 and the second positioning block 216 are respectively used to abut against the side of the mounting portion 221 facing the side wall and the side facing the rear wall, thereby positioning the mounting portion 221 so that the mounting portion 221 can be correctly installed at a preset position during installation, thereby improving the consistency and accuracy of the weighing sensor 220 during installation. In addition, by providing the first positioning block 215 and the second positioning block 216, a certain limiting effect can be exerted on the weighing sensor 220 after installation, thereby preventing the weighing sensor 220 from moving when receiving a load.

[0082] Specifically, since one side of the weighing sensor 220 is wrapped with silicone and cannot be positioned, the first positioning block 215 and the second positioning block 216 in the above embodiment only position the two sides of the mounting portion 221 and are installed by manual pressing. In this way, while achieving the positioning effect, damage to the weighing sensor 220 can also be prevented.

[0083] Furthermore, the height of the first positioning block 215 and the second positioning block 216 is 8.3 mm-8.7 mm.

[0084] Please refer to FIG. 2 to FIG. 4 . In one embodiment, the weighing sensor further includes a first fastener, which passes through the installation area 212 and is connected to the installation portion 221 .

[0085] The first fastener passes through the installation area 212 and is connected to the installation portion 221 , thereby fixing the load cell 220 . The fixing effect is reliable and the cost is low.

[0086] Please refer to Figures 2 to 4. In one embodiment, the first fastener includes a first mounting bolt 223. The mounting area 212 is provided with a first mounting through hole.
