By installing multiple groups of partition plates, it can classify and store the objects purchased by the intelligent shopping robot based on visual recognition. Specifically, the partition plates can move according to the volume of the stored objects to adjust the space inside the box, achieving the purpose of adjusting the space inside the box, classifying and storing the purchased objects, and preventing the purchased objects from scattering. However, during the process of classification and storage, due to the problem that similar items are stacked in one area, it is easy to cause uneven distribution of the center of gravity of the goods, leading to problems such as the shopping basket tilting and goods falling. Summary of the Invention

[0005] The purpose of the present invention is to provide a supermarket intelligent shopping guide robot and method based on automatically adjusting the capacity of a shopping basket to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: A supermarket intelligent shopping guide robot based on automatically adjusting the capacity of a shopping basket, comprising: An intelligent robot body, on which a placement basket is provided. A placement cavity is formed inside the placement basket, and a side bottom plate is slidably installed on one side of the placement basket; A folding plate group, provided with two groups and connected to the placement basket and the side bottom plate. When the folding plate group is unfolded, it can form another placement cavity with the placement basket and the side bottom plate; A driving component, arranged on the side bottom plate. The driving component can drive the folding plate group to unfold or retract by driving a connecting shaft connected to the folding plate group; A central component, connecting the placement basket and the side bottom plate, which can make the two placement cavities symmetrically distributed relative to the intelligent robot body when the folding plate group is opened.

[0007] As a further solution of the present invention: The folding plate group includes two connecting plates rotatably connected to the side bottom plate and the placement basket. One end of the two connecting plates facing each other is connected by a connecting piece, and the connecting plate connecting the side bottom plate is connected to the connecting shaft; An arc-shaped groove is provided on the side bottom plate, and the connecting shaft can move in the arc-shaped groove.

[0008] As a further solution of the present invention: Two right-angle abutting parts are diagonally arranged on the side part of the connecting plate, and the right-angle abutting parts can make the two connecting plates coplanar when the connecting plates are unfolded.

[0009] As a further solution of the present invention: The driving component includes a follower rotatably connected to the connecting shaft and a double-headed electric telescopic rod passing through the follower and slidably connected to the follower. The double-headed electric telescopic rod is connected to the follower through an elastic structure; The driving component further includes a driving shaft connecting the double-headed electric telescopic rod, and the driving shaft is in rolling fit with a driving plate provided on the side bottom plate.

[0010] As a further solution of the present invention: The driving shaft is connected to the double-headed electric telescopic rod through a connecting rod; The elastic structure includes a first spring and a second spring sleeved on the double-headed electric telescopic rod and symmetrically arranged on both sides of the follower. One end of the first spring is connected to the follower, and the other end is connected to the end of the double-headed electric telescopic rod. One end of the second spring is connected to the follower, and the other end is connected to the connecting rod.

[0011] As a further solution of the present invention: An inclined groove with an opening facing the placement basket is provided on the driving plate, and the driving shaft can roll in the inclined groove, and the width of the inclined groove gradually increases along the direction from its end to the opening.

[0012] As a further solution of the present invention: A bearing bracket is provided on the intelligent robot body, and two support rollers are rotatably installed on the bearing bracket. The support rollers are in rolling connection with a telescopic rod group connecting the placement basket and the side bottom plate.

[0013] As a further solution of the present invention: The centering component includes a guiding member disposed on the supporting bracket and a sliding connection portion capable of sliding along the length direction of the guiding member. Two sets of pulling rods are symmetrically and rotatably installed on the sliding connection portion. One set of the pulling rods is rotatably connected to the placement basket, and the other set of the pulling rods is rotatably connected to the side bottom plate.

[0014] As a further solution of the present invention: A partition capable of moving in the vertical direction is slidably installed on one side of the placement basket.

[0015] A usage method of a supermarket intelligent shopping guide robot based on automatically adjusting the capacity of the shopping basket, including: At the beginning of use, the folding plate group is in a retracted state. At this time, goods can only be stored in the placement basket. When the intelligent robot body detects that the storage quantity in the placement basket reaches a preset value, the intelligent robot body controls the driving component to act, so that the folding plate group unfolds and forms another placement cavity. At the same time, the centering component can make the two placement cavities symmetrically distributed relative to the intelligent robot body, and the partition can move upward, so that the goods placed in the placement basket can partially slide into the placement cavity formed by the side bottom plate and the folding plate group.

[0016] Compared with the prior art, the beneficial effects of the present invention are: First of all, the folding plate group can be unfolded or retracted according to the usage needs, so that when the shopping quantity is small, the folding plate group can occupy less space on the side of the placement basket, improving the overall flexibility of the shopping guide robot; only when the shopping quantity is large, the folding plate group forms another placement cavity by unfolding to meet the shopping needs of customers; Secondly, by directly driving the connecting plate to control the unfolding and retracting of the folding plate group, on the one hand, the speed of unfolding or retracting can be increased, and on the other hand, the stability of the folding plate group in the unfolded and retracted states can be improved; At the same time, when the folding plate group unfolds, the two formed placement cavities can be symmetrically distributed, so that the center of gravity can be evenly distributed. And during the opening process of the folding plate group, the goods in the placement basket can partially slide into the placement cavity formed by the folding plate group and the side bottom plate, so as to avoid the phenomenon that when the folding plate group unfolds, due to the goods being piled up in the placement basket, the center of gravity is unevenly distributed, the intelligent robot body is unstable or overturns during movement.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In addition, the elements in the present invention are referred to as "fixed to" or "disposed on" another element, and it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0030] Please refer to Figures 1 to 10 , in the embodiment of the present invention, a supermarket intelligent shopping guide robot based on automatically adjusting the capacity of a shopping basket includes: an intelligent robot body 1, a folding plate group, a driving component and a centering component.

[0031] A placement basket 3 is provided on the intelligent robot body 1. A placement cavity is formed in the placement basket 3, and a side bottom plate 6 is slidably installed on one side of the placement basket 3. Among them, the intelligent robot body 1 can scan the items placed in the placement basket 3 to calculate the cumulative price of the items, so that when the customer settles the bill, there is no need to queue due to calculating the price of the items, improving the work efficiency at the cashier desk. Specifically, a scanning gun (not shown in the figure) is provided at the head of the intelligent robot body 1. When the customer selects items, the scanning gun can be used to scan the barcodes on the items, so that the intelligent robot body 1 can obtain the price information of the items.

[0032] There are two sets of the folding plate groups, which are connected to the placement basket 3 and the side bottom plate 6. When the folding plate groups are unfolded, another placement cavity can be formed with the placement basket 3 and the side bottom plate 6. Specifically, a guiding portion 602 is provided on the side of the side bottom plate 6, and the guiding portion 602 is slidably engaged with a guiding member 9 provided on the side of the placement basket 3. The cross-section of the side bottom plate 6 in the vertical direction of the space is in an "L" shape, and the upper surface of the bottom of the side bottom plate 6 is in a sliding fit with the lower surface of the placement basket 3, so that when the folding plate groups are retracted, a large area of overlap can be formed between the side bottom plate 6 and the bottom of the placement basket 3. At the same time, when the folding plate groups are unfolded, the guiding portion 602 can slide relative to the guiding member 9, and the cooperation between the guiding portion 602 and the guiding member 9 can, on the one hand, ensure the close fitting state between the side bottom plate 6 and the bottom of the placement basket 3, thereby improving the structural stability of the device, and on the other hand, can support one end of the side bottom plate 6 facing the placement basket 3 when the folding plate groups are unfolded, so as to prevent the side bottom plate 6 from separating from the bottom of the placement basket 3 due to gravity when an item is placed on the side bottom plate 6, causing the item to slide off.

[0033] The folding plate groups include two sets of connecting plates 4 that are rotatably connected to the side bottom plate 6 and the placement basket 3. One ends of the two sets of connecting plates 4 facing each other are connected by a connecting member 5, and the connecting plate 4 connected to the side bottom plate 6 is connected to the connecting shaft 10. Further, two right-angle abutting portions 401 are diagonally arranged on the side of the connecting plate 4. The right-angle abutting portions 401 can make the two sets of connecting plates 4 coplanar when the connecting plates 4 are unfolded. Among them, the significance of setting the connecting member 5 is that the thickness generated after the two sets of connecting plates 4 are folded can be minimized, thereby reducing the space occupancy rate of the folding plate groups on the side of the placement basket 3 in the retracted state.

[0034] An arc-shaped groove 601 is provided on the side bottom plate 6, and the connecting shaft 10 can move within the arc-shaped groove 601.

[0035] In this embodiment, the connecting plate 4 connected to the side bottom plate 6 has two states. One is that the connecting plate 4 can be perpendicular to the side of the side bottom plate 6. At this time, the folding plate groups are in the unfolded state, so that the folding plate groups, the side bottom plate 6 and the side of the placement basket 3 can form another placement cavity to improve the placement capacity of items. The other is the state where the connecting plate 4 is parallel to the side of the side bottom plate 6. At this time, the folding plate groups are in the retracted state. At this time, the side bottom plate 6 and the folding plate groups can be retracted to the minimum state, so that less space can be occupied on the side of the placement basket 3. Through this unfolded or retracted setting, during shopping, the number of placement cavities can be adjusted according to the actual demand of the customer to meet the shopping needs of the customer.

[0036] Among them, in the unfolded state, the right-angle abutting portion 401 of one set of connecting plates 4 can abut against the side portion of the side bottom plate 6 and the side portion of the connecting member 5, while the right-angle abutting portion 401 of the other set of connecting plates 4 can abut against the side portion of the connecting member 5 and the side portion of the placing basket 3. When the folding plate group is in the unfolded state and goods are placed in the placing cavity, the goods will not form a gap with the side portion of the side bottom plate 6 due to the extrusion of the connecting plates 4 causing the connecting plates 4 to bend outwards, thereby avoiding the goods from slipping out of the placing cavity to a certain extent. Further, the position state of the above-mentioned connecting plates 4 can be understood as follows: the connecting plates 4 can be folded inwards and retracted or unfolded outwards, and the maximum degree of unfolding is the state where the connecting member 5 and the two sets of connecting plates 4 are coplanar.

[0037] Please refer to Figures 6 to 8 , the driving assembly is arranged on the side bottom plate 6. The driving assembly can drive the folding plate group to unfold or retract by driving the connecting shaft 10 connected to the folding plate group. The driving assembly includes a follower 11 rotatably connected to the connecting shaft 10 and a double-headed electric telescopic rod 12 passing through the follower 11 and slidably connected to the follower 11. The driving shaft 16 is connected to the double-headed electric telescopic rod 12 through a connecting rod 15. The double-headed electric telescopic rod 12 is connected to the follower 11 through an elastic structure. The elastic structure includes a first spring 13 and a second spring 14 sleeved on the double-headed electric telescopic rod 12 and symmetrically arranged on both sides of the follower 11. One end of the first spring 13 is connected to the follower 11, and the other end is connected to the end of the double-headed electric telescopic rod 12. One end of the second spring 14 is connected to the follower 11, and the other end is connected to the connecting rod 15.

[0038] The driving assembly further includes a driving shaft 16 connected to the double-headed electric telescopic rod 12. The driving shaft 16 is in rolling fit with a driving plate 17 arranged on the side bottom plate 6. Specifically, the driving plate 17 is provided with an inclined groove 1701 with an opening facing the placing basket 3. The driving shaft 16 can roll in the inclined groove 1701, and the width of the inclined groove 1701 gradually increases along the direction from its end to the opening.

[0039] In this embodiment, an electrically connected relationship is formed between the intelligent robot body 1 and the double-headed electric telescopic rod 12, so that under the control of the intelligent robot body 1, the double-headed electric telescopic rod 12 can perform telescopic actions. Specifically, there are the following two motion states: One is that the folding plate group switches from the unfolded state to the folded state. During this process, in the initial state, the connecting shaft 10 is at one end of the arc-shaped groove 601 close to the placement basket 3. At this time, the action end of the double-headed electric telescopic rod 12 is in the upward extended state, so that the connecting shaft 10 is at the end of this end of the arc-shaped groove 601. And when placing goods in this placement cavity, the goods can form a squeezing state on the connecting plate 4, so that the folding plate group can be in a stable unfolded state. When the double-headed electric telescopic rod 12 acts, the two action ends of the double-headed electric telescopic rod 12 can retract relatively. At this time, the double-headed electric telescopic rod 12 can pull the two sets of follower parts 11 to move closer to each other, so that the connecting shaft 10 moves along the arc-shaped groove 601. At this time, the connecting plate 4 can deflect, and the connecting piece 5 is used to drive the other set of connecting plates 4 to deflect, so that the folding plate group folds inward, and at the same time drives the side bottom plate 6 to act towards the placement basket 3 to cancel the use of this placement cavity, eliminating the problem of excessive space occupancy caused by the simultaneous existence of the two placement cavities.

[0040] When the connecting shaft 10 moves in the arc-shaped groove 601, when it moves to the end of the arc-shaped groove 601 far from the placement basket 3, at this time, since the angle between the connecting plate 4 and the double-headed electric telescopic rod 12 gradually increases, the double-headed electric telescopic rod 12 needs to apply a greater pulling force to drive the connecting plate 4 to continue to deflect. However, in this embodiment, when the connecting plate 4 deflects to a certain angle, the driving shaft 16 can enter the inclined groove 1701. At this time, the cooperation between the driving shaft 16 and the inclined groove 1701 can be used to drive the connecting plate 4 to deflect more easily, avoiding damage to the connecting shaft 10 due to the excessive force of the double-headed electric telescopic rod 12 acting on the connecting shaft 10.

[0041] Furthermore, when the driving shaft 16 moves in the inclined groove 1701, the first spring 13 can be compressed, and the second spring 14 can be released, so as to play a role of making way, enabling the driving shaft 16 to move relative to the connecting shaft 10.

[0042] It should be noted that the significance of the width of the inclined groove 1701 gradually increasing along the direction from its end towards the opening is that since the double-headed electric telescopic rod 12 and the follower part 11 are elastically connected, when the connecting plate 4 deflects to fold the folding plate group, when the connecting plate 4 deflects to a certain angle, the first spring 13 will definitely be compressed to a certain extent. At this time, since the width of the opening of the inclined groove 1701 is larger, it is convenient for the driving shaft 16 to enter the inclined groove 1701.

[0043] Second, when the folding plate group switches from the retracted state to the deployed state, during this process, the connecting shaft 10 is at the end of the arc-shaped groove 601 away from the placement basket 3. At this time, by the cooperation of the drive shaft 16 and the inclined groove 1701, the connecting shaft 10 can be forced to move in the arc-shaped groove 601, driving the connecting plate 4 to perform a deflection action, avoiding the situation in extreme cases (when the length direction of the connecting plate 4 is parallel to the length direction of the double-headed electric telescopic rod 12), when the action end of the double-headed electric telescopic rod 12 moves outward, it is unable to drive the connecting plate 4 to perform a deflection action.

[0044] Please refer to Figure 4 、 Figures 9 to 10 , a support bracket 2 is provided on the intelligent robot body 1, two groups of support rollers 22 are rotatably installed on the support bracket 2, and the support rollers 22 are in rolling connection with the telescopic rod group 21 connecting the placement basket 3 and the side bottom plate 6. When the side bottom plate 6 moves, it can drive the placement basket 3 to move synchronously through the centering component. At this time, the length of the telescopic rod group 21 can be adaptively increased or shortened and maintained in a rolling connection state with the support rollers 22, thereby reducing the resistance when the side bottom plate 6 and the placement basket 3 move relative to each other and improving the stability between the two.

[0045] The centering component connects the placement basket 3 and the side bottom plate 6. The centering component can make the two placement cavities symmetrically distributed relative to the intelligent robot body 1 when the folding plate group is opened. The centering component includes a guide member 20 provided on the support bracket 2 and a sliding connection portion 19 that can slide along the length direction of the guide member 20. Two groups of pull rods 18 are symmetrically and rotatably installed on the sliding connection portion 19. One group of the pull rods 18 is rotatably connected to the placement basket 3, and the other group of the pull rods 18 is rotatably connected to the side bottom plate 6. The guide member 20 is located in the middle of the intelligent robot body 1.

[0046] During the process of the folding plate group unfolding, the side bottom plate 6 can move away from the placement basket 3. At this time, the distance between the two will increase. At the same time, the side bottom plate 6 can pull the sliding connection portion 19 to move upward through the pull rod 18, and the sliding connection portion 19 is connected to the placement basket 3 through another pull rod 18, and the sliding connection portion 19 can slide along the length direction of the guide member 20, so that when the side bottom plate 6 moves away from the placement basket 3, the placement basket 3 can move relative to the guide member 20 in a direction away from the side bottom plate 6. When the folding plate group is completely opened, the two formed placement cavities can be symmetrically arranged relative to the guide member 20, so that when there are goods stored in both placement cavities, the intelligent robot body 1 can be balanced in force, avoiding the phenomenon that the intelligent robot body 1 is unstable or overturns during movement due to the center of gravity offset.

[0047] One side of the placement basket 3 is slidably installed with a partition plate 7 capable of moving in the vertical direction. The partition plate 7 is connected to a stop plate 8 arranged on the side of the placement basket 3. One end of the stop plate 8 away from the partition plate 7 is fixedly connected to the sliding connection part 19.

[0048] When the folding plate group is retracted and the placement basket 3 stores goods with a predetermined capacity, at this time, the partition plate 7 is at the low point of the stroke, so as to prevent the goods from slipping out of the placement basket 3. At the same time, the folding plate group will unfold. During the unfolding process, since the sliding connection part 19 can move upward, the sliding connection part 19 can drive the partition plate 7 to move upward through the stop plate 8, so that the two placement cavities can be in a conducting state. At this time, part of the goods in the placement basket 3 can slide into the placement cavity formed by the side bottom plate 6 and the folding plate group, so as to achieve a certain effect of center of gravity transfer, and avoid the phenomenon that when the folding plate group unfolds, due to the goods being piled up in the placement basket 3, the center of gravity distribution is uneven, and further avoid the instability of the intelligent robot body 1 or the phenomenon of tipping over during movement due to the center of gravity offset.

[0049] It should also be noted that in the present application, only one set of centering components is provided. This set of centering components can only drive one end of the partition plate 7 to move upward, while the other end of the partition plate 7 slides upward passively. In the actual use process, another set of centering components can be arranged on one side of the placement basket 3 relative to the centering components, so that when the centering components act, both ends of the partition plate 7 can be driven to move upward synchronously, thereby avoiding the phenomenon of jamming of the partition plate 7 during the upward movement.

[0050] A method for using a supermarket intelligent shopping guide robot based on automatically adjusting the capacity of a goods basket as described above, including: At the beginning of use, the folding plate group is in a retracted state. At this time, goods can only be stored in the placement basket 3. When the intelligent robot body 1 detects that the storage capacity in the placement basket 3 reaches a preset value, the intelligent robot body 1 controls the driving component to act, so that the folding plate group unfolds and forms another placement cavity. At the same time, the centering component can make the two placement cavities symmetrically distributed relative to the intelligent robot body 1, and the partition plate 7 can move upward, so that part of the goods placed in the placement basket 3 can slide into the placement cavity formed by the side bottom plate 6 and the folding plate group.
