[0036] According to one aspect of the present application, a tray 10 is provided. Figures 1 to 7 As shown, the tray 10 includes a tray body 110 and a backing plate 120. The tray body 110 includes a supporting plate and an edge portion 112. The edge portion 112 surrounds the supporting plate. The supporting plate and the edge portion 112 enclose a receiving space. The backing plate 120 is respectively attached to the supporting plate and the edge portion 112. At least part of the backing plate 120 is located in the receiving space, and the orthographic projection of the supporting plate on the backing plate 120 is located in the backing plate 120. In the tray 10 of the present application, the food is placed on the side of the backing plate 120 facing away from the tray body 110. Since the orthographic projections of the supporting plate on the backing plate 120 are all located in the backing plate 120, the gap between the tray body 110 and the backing plate 120 will not appear on the side of the backing plate 120 used to carry the food. In this way, the soup spilled from the food will only appear on the surface of the pad 120 used for supporting the food, and only the surface of the pad 120 used for supporting the food needs to be cleaned, which reduces the difficulty of cleaning the tray 10. The tray will be described below in combination with Example 1 and Example 2.

[0037] Embodiment 1

[0038] like Figure 1 and Figure 2 As shown, the orthographic projections of the supporting plate 111a and the edge 112 on the pad 120 are both located inside the pad 120, the tray body 110 is plate-shaped, the edge 112 is arranged along the extension direction of the four edges of the supporting plate 111a, and the edge 112 is connected at the head and tail, so that the edge 112 and the supporting plate 111a enclose a storage space, and the arrangement of the edge 112 can prevent food from slipping on the tray 10.

[0039] Furthermore, if Figure 2 As shown, mounting holes 114 are opened on the two opposite sides of the edge portion 112, and bolts are passed through the mounting holes 114 and the fixing holes on the shell 20 of the robot to fix the two opposite sides of the edge portion 112 on the inner wall of the shell 20, thereby fixing the tray body 110 inside the shell 20.

[0040] In addition, the height of the edge 112 is greater than the diameter of the mounting hole 114, so that the edge 112 can meet the requirement of fixing the tray body 110 by bolts. At the same time, when the tray 10 is installed inside the shell 20, a detection sensor for detecting items on the tray 10 is provided on the upper part of the tray 10, and the distance between the supporting plate 111a and the item detection sensor located on the shell 20 is greater than the height of the edge 112, so as to ensure the accuracy of the detection of the item detection sensor.

[0041] Optionally, the tray body 110 is stamped and formed, and the stamped tray body 110 has a higher structural strength, ensuring the load capacity of the tray 10, so that the tray 10 can meet the load requirements for food. Specifically, the support plate and the edge are stamped and formed as one piece, and the tray body 110 can be made of metal material.

[0042] Preferably, the load-bearing capacity of the tray 10 is greater than or equal to 15 kg, so that the tray 10 can meet the load-bearing requirements for items weighing 15 kg or less, and can meet the load-bearing requirements of the tray 10 when the robot delivers meals.

[0043] Furthermore, the thickness of the tray body 110 is less than 1.5 mm. For example, the thickness of the tray body 110 can be 1 mm, 1.2 mm, or 1.5 mm. The tray body 110 with the above thickness can reduce the weight of the tray body 110 while meeting the structural strength requirements of the tray body 110. Preferably, the thickness of the tray body 110 is 1 mm. In the present structural metal part stamping process, the tray is now 1 mm thick, and the strength is about 4 times that of a machined tray.

[0044] In this embodiment, if Figure 2 As shown, a receiving groove 113 is provided on the supporting plate 111a, and at least a part of the anti-slip portion 124 described below is located in the receiving groove 113. The anti-slip portion 124 cooperates with the receiving groove 113 to ensure the stability of the fixation between the pad 120 and the tray body 110, thereby preventing the pad 120 from sliding off the tray body 110.

[0045] Furthermore, the receiving groove 113 may be annular, and the inner edge and the outer edge of the receiving groove 113 are both in the shape of a rectangular parallelepiped.

[0046] Optionally, there can be two receiving grooves 113, one of which is located in the middle of the supporting plate 111a, and the other is arranged along the edge of the supporting plate 111a. The two receiving grooves 113 respectively cooperate with the two anti-slip parts 124 included in the pad 120 to ensure the stability of the fixation between the tray body 110 and the pad 120 to prevent the pad 120 from sliding off the tray body 110.

[0047] Furthermore, if Figure 2 As shown, a first notch 115 is provided on the edge 112, and the position of the first notch 115 corresponds to the position of a second notch 126 on the pad 120 described below, so that the first notch 115 is connected to the second notch 126. This allows the entire tray 10 to have a notch position, so that food supported on the pad 120 can be taken through the notch position or food can be placed on the pad 120.

[0048] In this embodiment, the pad 120 includes a main body 121, an extension 122 and a protrusion 123, one side of the extension 122 is connected to the main body 121, and the other side of the extension 122 is connected to the protrusion 123, the main body 121 is in contact with the side of the supporting plate 111a facing the accommodation space, the extension 122 is in contact with the side of the supporting plate 111a facing the accommodation space, and at least part of the protrusion 123 is in contact with the side of the edge 112 facing away from the supporting plate 111a. When the pad 120 is mounted on the tray body 110, the main body 121 and the extension 122 are located inside the accommodation space, the protrusion 123 is located outside the accommodation space, and the protrusion 123 is located on the upper side of the edge 112. Observing the entire tray 10 from the side where the pad 120 is located in a direction perpendicular to the supporting plate 111a, the protrusion 123 and the extension 122 completely cover the edge 112, and the main body 121 completely covers the supporting plate 111a. The gap between the pad 120 and the tray body 110 is located on the side of the edge 112. The gap between the pad 120 and the tray body 110 will not be exposed to a position where soup can spill, thereby preventing soup from spilling into the gap between the pad 120 and the tray body 110. When cleaning, only the soup on the surface of the pad 120 needs to be wiped, thereby reducing the difficulty of cleaning the tray 10.

[0049] Furthermore, the cross-section of the protrusion 123 can be circular, and the entire protrusion 123 can be in the shape of a cylinder connected end to end. The diameter of the circular cross-section of the protrusion 123 is larger than the thickness of the tray body 110, so that the gap between the protrusion 123 and the edge 112 appears on the side of the edge 112 facing away from the accommodating space, thereby preventing soup from entering the gap between the tray body 110 and the pad 120, thereby reducing the difficulty of cleaning the tray 10.

[0050] Optionally, the form of the protrusion 123 is not limited to Figure 2 In the form, for example, the protrusion 123 may include two parts connected to each other, one part of which is in contact with the upper surface of the edge 112, and the other part is in contact with the side of the edge 112 facing away from the accommodating space, so that a gap between the protrusion 123 and the edge 112 appears on the side of the edge 112 facing away from the accommodating space, thereby preventing soup from entering the gap between the tray body 110 and the pad 120.

[0051] like Figure 4 As shown, the pad 120 also includes an anti-slip portion 124, which protrudes from the main body 121 toward the supporting plate 111a. The supporting plate 111a is provided with a receiving groove 113. At least part of the anti-slip portion 124 abuts against the receiving groove 113. The friction between the anti-slip portion 124 and the receiving groove 113 can prevent the pad 120 and the tray body 110 from slipping, thereby achieving fixation between the pad 120 and the tray body 110.

[0052] Furthermore, if Figure 4 As shown, the anti-slip portion 124 may include a plurality of anti-slip strips 1241. For any anti-slip strip 1241 among the plurality of anti-slip strips 1241, the anti-slip strip 1241 crosses with at least one other anti-slip strip 1241, and one end of any anti-slip strip 1241 facing away from the main body 121 abuts against the bottom of the receiving groove 113. In this way, the plurality of cross-arranged anti-slip strips 1241 abut against the bottom of the receiving groove 113, which can ensure the friction between the anti-slip portion 124 and the receiving groove 113, thereby ensuring the stability of the fixing between the pad 120 and the tray body 110.

[0053] In addition, the anti-slip portion 124 may further include two fixing strips 1242, and the fixing strips 1242 are fixed to the main body 121. The fixing strips 1242 are connected head to tail, and the fixing strips 1242 are rectangular, wherein one fixing strip 1242 is located outside the other fixing strip 1242, so that a placement space is formed between the two fixing strips 1242, and a plurality of anti-slip strips 1241 are located in the placement space between the two fixing strips 1242, and the two ends of the anti-slip strip 1241 are respectively connected to the two fixing strips 1242, and the side of the fixing strip 1242 facing away from the main body 121 abuts against the bottom of the receiving groove 113, thereby further improving the friction between the anti-slip portion 124 and the receiving groove 113.

[0054] Optionally, the number of the anti-slip parts 124 can be selected according to demand, for example, the number of the anti-slip parts 124 can be one, two or more, and each anti-slip part 124 is correspondingly provided with a receiving groove 113.

[0055] Preferably, there are two anti-slip portions 124 , and the two anti-slip portions 124 correspond to the two receiving grooves 113 , respectively, so as to further improve the stability of the fixation between the tray body 110 and the pad 120 .

[0056] like Figure 4 As shown, the pad 120 also includes a reinforcement portion 125, which is arranged on the side of the extension portion 122 facing away from the accommodating space. The reinforcement portion 125 is in contact with the side of the extension portion 122 facing the accommodating space. The reinforcement portion 125 can improve the structural strength of the extension portion 122, thereby improving the structural strength of the pad 120.

[0057] In addition, the extension portion 122 is provided with a second notch 126, and a portion of the protrusion 123 is fitted with the bottom of the second notch 126, so that the edge of the entire extension portion 122 is covered by the protrusion 123, and the first notch 115 is connected to the second notch 126, so that the food supported on the pad 120 can be taken through the first notch 115 and the second notch 126 or the food can be placed on the pad 120.

[0058] Optionally, the pad 120 may be made of materials such as rubber.

[0059] This embodiment adopts a fully wrapped dining tray mat with a load-bearing dining layer structure. The tray mat fully wraps the tray, and the edge of the tray reduces injuries to people. Plastic is coated on the outside of the metal tray to prevent items from slipping while improving cleaning power and reducing costs.

[0060] Embodiment 2

[0061] like Figure 5 , Figure 6 and Figure 7 As shown, there are two edges 112, which are arranged on two opposite sides of the supporting plate 111b, and the supporting plate 111b and the two edges 112 are integrally die-cast. The two edges 112 and the supporting plate 111b enclose a receiving space, and the provision of the edges 112 can prevent food from sliding off the tray 10.

[0062] Preferably, the supporting plate 111 b is a metal hollow skeleton structure, which reduces the weight of the supporting plate 111 b , reduces the manufacturing cost of the tray body 110 , and reduces the weight of the tray body 110 .

[0063] Furthermore, if Figure 2 As shown, mounting holes 114 are provided on the two edges 112 , and bolts are passed through the mounting holes 114 and the fixing holes on the shell 20 of the robot to fix the two edges 112 on the inner wall of the shell 20 , thereby fixing the tray body 110 inside the shell 20 .

[0064] In addition, the thickness of the tray body 110 is less than or equal to 2 mm.

[0065] like Figure 5 and Figure 7 As shown, the pad 120 includes a main body 121 and a protrusion 123. The main body 121 is fitted with the supporting plate 111b. There are two protrusions 123. The two protrusions 123 are respectively arranged on both sides of the pad 120. The two protrusions 123 respectively cover two parts of the supporting plate 111b where the edge 112 is not arranged, thereby preventing the soup from spilling into the gap between the pad 120 and the tray body 110, and reducing the difficulty of cleaning the tray 10.

[0066] Optionally, the supporting plate 111b includes a first notch, the main body 121 is provided with a second notch 126, and the first notch 115 is connected to the second notch 126, so that the entire tray 10 has a notch position, so that the food supported on the pad 120 can be taken through the notch position or the food can be placed on the pad 120.

[0067] In the tray 10 of the present application, when the entire tray 10 is observed from the side where the backing plate 120 is located in a direction perpendicular to the supporting plate 111b, the backing plate 120 completely covers the tray body 110. When the food is placed on the backing plate 120, the gap between the backing plate 120 and the tray body 110 will not be exposed to the position where the soup can spill, thereby reducing the difficulty of cleaning the tray 10.

[0068] According to another aspect of the present application, a robot is provided, which includes a shell 20 and the above-mentioned tray 10. The shell 20 is a hollow structure, and the edge 112 of the tray 10 is fixed to the inner wall of the shell 20 by bolts. The robot has the same technical effect as the above-mentioned tray 10, which will not be repeated here.

[0069] Optionally, the robot may be a delivery robot for delivering meals.

[0070] Furthermore, the robot also includes a mobile chassis 30, a function controller that provides user operations, a bottom-level controller for map generation and path planning, and an element controller that controls the mobile unit and the environment detection unit; the mobile chassis 30 is provided with at least two sets of driving wheels 320, and each set of driving wheels 320 is respectively located on one side of the mobile chassis 30; the element controller controls the travel speed of the driving wheels 320.

[0071] At least one turn signal unit is provided at the bottom of the chassis, and each turn signal unit includes at least one turn signal 310; the mobile unit is provided with at least two sets of driving wheels 320, and each set of driving wheels 320 is respectively located on one side of the chassis; the element controller controls the travel speed of the driving wheels 320; and controls the turn signal 310 in the turn signal unit to light up in a preset manner when the robot turns.

[0072] Specifically, among the driving wheels 320 provided in the mobile unit, at least one group of driving wheels 320 is used as the left driving wheel 320, and at the same time, at least one group of driving wheels 320 is used as the right driving wheel 320, and the left driving wheel 320 and the right driving wheel 320 are located on opposite sides of the chassis. Optionally, the mobile unit may also include at least two groups of driven wheels, one group of driving wheels 320 corresponds to one group of driven wheels, wherein at least one group of driven wheels is used as the left driven wheel, and at the same time, at least one group of driven wheels is used as the right driven wheel, and the left driven wheel and the right driven wheel are used to assist the left driving wheel 320 and the right driving wheel 320 in driving the housing 20 and the chassis of the robot to move, thereby reducing the load pressure of the driving wheel 320.

[0073] The robot provided by the embodiment of the utility model can alert pedestrians by controlling the turn signal light 310 to light up by the component controller when the robot turns.

[0074] On the basis of the above technical solution, optionally, when the speed difference of the driving wheels 320 on both sides of the chassis is greater than a preset value, the component controller controls the turn signal 310 in the turn signal unit to light up in a preset manner.

[0075] Optionally, the robot further includes a voice module, which is electrically connected to the component controller; when the robot turns, the component controller controls the voice module to issue a voice prompt message.

[0076] LiDAR systems can be installed in robotic devices, such as Figure 8 As shown, the laser radar system can rotate along a set plane so that the photoelectric receiving array of the laser radar system forms a scanning cylinder.

[0077] The laser radar system can be set at the slit of the shell 20 of the robot, so that it is easy to send out laser signals to detect surrounding objects. The above-mentioned laser radar system includes a photoelectric receiving array and a laser emitting unit array, so that when the laser radar system rotates along the set plane, the photoelectric receiving array can form a scanning cylinder, thereby increasing the scanning area, facilitating the acquisition of the details of the object shape, and avoiding the robot device from colliding with obstacles. If the laser radar system only includes a single photoelectric receiving unit and a single laser emitting unit, the laser radar system can only measure the shape of an object in a circle after rotating along the set plane, and cannot obtain the shape of complex objects in time, which is easy to cause collisions and endanger personal and property safety. Optionally, the above-mentioned set plane can be a horizontal plane, which is convenient for the robot device to detect objects during movement. In addition, other set planes, such as vertical planes, can be selected according to user needs, and this embodiment does not limit this.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
