[0002] Whenever my parents take me to the supermarket to shop, I have developed a keen interest in supermarket shopping carts. Currently, the scale of supermarkets is getting bigger and bigger. I find that in this case, the traditional hand-pushing shopping carts have shown many shortcomings.

[0003] In super-large supermarkets, customers need to walk a long distance when pushing a shopping cart from one shelf to another, which is time-consuming and laborious. Moreover, due to the large size of the supermarket and the wide variety of goods, customers cannot find the products they want in time, which greatly affects the shopping experience and wastes time. In addition, the child seats on existing shopping carts are only made of foldable plastic and have no fixed structure. They are easy to shrink and pinch children when in use, and cannot sense the presence of adults, which can easily lead to children getting lost.

[0004] When customers use shopping carts, the random placement of items in the shopping cart easily leads to unbalanced forces inside the shopping cart. Existing shopping carts cannot be flexibly adjusted according to the forces in the basket, making the shopping carts prone to tipping over and causing dangerous accidents. In addition, some customers tend to push the shopping carts out of the supermarket, increasing the workload of supermarket staff in collecting and sorting the shopping carts. At the same time, since the shopping carts do not have a self-service code scanning function, it is inconvenient for customers to check out quickly, resulting in a poor shopping experience for customers.

Due to the elastic support of the second spring 7, the latch 6 is kept Rotate the seat cushion 8 upward to lock and fix it, preventing the seat cushion 8 from moving and shrinking during use, which may cause the child to be pinched, effectively improving the safety of the device. At the same time, the third spring 9 is elastically supported between the seat cushion 8 and the first pressure detector 10, so that when the child sits on the first pressure detector 10, the elastic deformation characteristics of the third spring 9 make the child's buttocks more comfortable. When the child sits on the first pressure detector 10, the first pressure detector 10 can sense the pressure changes and transmit the collected signals to the tablet computer 14 through the control box 11, so that the tablet computer 14 can know that there is a child sitting on the shopping cart.

[0032] A control box 11 is embedded in the upper left side of the shopping cart basket 1, a support rod 12 is welded to the middle position of the left top of the shopping cart basket 1, and a human infrared detector 13 is fixedly installed in the middle position of the left side of the support rod 12, a tablet computer 14 is fixedly installed above the support rod 12, a barcode scanner 15 is embedded on the right side of the top of the support rod 12, and an electronic tag sensor 16 is fixedly installed in the middle position of the bottom of the shopping cart basket 1. The input end of the control box 11 is connected to the ultrasonic detector 2, the first pressure detector 10, the human infrared detector 13, the barcode scanner 15, the electronic tag sensor 16 and the second pressure detector 21 through a wire. The output end of the control box 11 is designed to be electrically connected to the input end of the first electric push rod 19 and the second electric push rod 30 through a wire. The interior of the control box 11 includes a circuit control board, a battery, and a WiFi module. The circuit control board can control the extension or contraction of the first electric push rod 19 and the second electric push rod 30. The battery provides power support for the ultrasonic detector 2, the first pressure detector 10, the human infrared detector 13, the barcode scanner 15, the electronic tag sensor 16, the first electric push rod 19, the second pressure detector 21 and the second electric push rod 30. The WiFi module is used to transmit the signal to the flat panel. The tablet computer 14 transmits or receives the exchange. The tablet computer 14 has a built-in supermarket APP. The tablet computer 14 is connected to the supermarket's internal network, making it easy to retrieve the location of the goods in the supermarket through the APP, which is conducive to customers' quick shopping and improving the shopping experience. The QR code of the goods can be scanned by the barcode scanner 15, and the APP built into the tablet computer 14 can be used to check out and pay online, which improves the checkout speed and avoids customers waiting in long queues. The human infrared detector 13 can sense whether the adult customer using the shopping cart is near the shopping cart and transmit the collected signal to the tablet computer 14 through the control box 11. After analysis by the tablet computer 14 and combined with the information collected by the first pressure detector 10, if the adult customer leaves the shopping cart for too long when a child is present, the tablet computer 14 will issue a warning. If the adult does not return to the shopping cart, the tablet computer 14 will contact the supermarket staff through the network to handle the matter attentively, effectively improving the protection of the device for children and preventing children from getting lost. The electronic tag sensor 16 can sense the electronic tags installed in the restricted area of ​​the supermarket and transmit the collected signal to the tablet computer 14 through the control box 11. The use of multiple sets of sensors and the tablet computer 14 in conjunction with each other greatly improves the function of the shopping cart and makes it more convenient to use.

[0033] The left end bottom of the shopping cart basket 1 is hinged with a hinge block 17, and the bottom of the hinge block 17 is hinged with a base 18. The hinge block 17 and the shopping cart basket 1 are designed as a rotating structure, and the base 18 and the hinge block 17 are designed as a rotating structure. The rotation direction of the base 18 relative to the hinge block 17 and the rotation direction of the hinge block 17 relative to the shopping cart basket 1 are perpendicular to each other. By providing two sets of mutually perpendicular hinge axes, the shopping cart basket 1 can be rotated and adjusted at will relative to the base 18, which is convenient for adjusting the center of the device through the first electric push rod 19, which is flexible and convenient.

[0034] Four groups of first electric push rods 19 are evenly fixed above the base 18, and the outer sides of the four groups of first electric push rods 19 are respectively sleeved with fourth springs 20. The top of the first electric push rod 19 does not contact the bottom of the shopping cart basket 1 in its original state. The bottom of the fourth spring 20 is fixedly welded above the base 18, and the top of the fourth spring 20 is fixedly welded to the bottom of the shopping cart basket 1. When in use, the four groups of fourth springs 20 are elastically supported between the shopping cart basket 1 and the base 18. The elastic deformation characteristics of the fourth springs 20 greatly improve the shock absorption performance of the device, making the device more stable in use. At the same time, the tablet computer 14 can send instructions to the control box 11, which controls the first electric push rods 19 to push upward through the control box 11, adjust the center of gravity inside the shopping cart basket 1, ensure the stability of the center of gravity of the shopping cart, effectively prevent the shopping cart from tipping over due to unstable center of gravity, and greatly improve the safety of the device.

[0035] Four groups of second pressure detectors 21 are evenly installed on the bottom of the base 18, and the bottoms of the four groups of second pressure detectors 21 are respectively fixed with universal wheels 22. A threaded rod 23 is inserted on the left side of the base 18, and a connecting rod 24 is sleeved on the outer side of the threaded rod 23. The connecting rod 24 is designed to be a rotating structure with the base 18 through the threaded rod 23. The outer wall of the base 18 is evenly threaded, and a nut is sleeved on the bottom end of the base 18. The four groups of second pressure detectors 21 are respectively installed at four positions on the base 18 to collect the downward pressure applied by the shopping cart basket 1, and the collected pressure signal is transmitted to the tablet computer 14 through the control box 11 for analysis. By rotating the nut sleeved on the bottom end of the threaded rod 23, the nut and the threaded rod 23 are separated under the engagement of the thread. The threaded rod 23 can be removed from the left end of the base 18 by pulling it upward, so that the connecting rod 24 can be separated from the base 18, so that the form of the device can be changed according to the customer's usage requirements. The shopping cart can be used in a pushing or riding mode, which is flexible and convenient and can meet the usage requirements of different customers.

[0036] A support frame 25 is fixed to the lower left end of the connecting rod 24, a seat cushion 26 is fixedly installed above the connecting rod 24, a driving wheel 27 is hinged at the bottom of the supporting frame 25, and pedals 28 are fixed on both sides of the driving wheel 27, a paddle 29 is hinged inside the supporting frame 25, and a second electric push rod 30 is hinged at the lower left side of the paddle 29, the driving wheel 27 and the supporting frame 25 are designed as a rotating structure, teeth are evenly welded on the inner ring of the driving wheel 27, and the teeth are designed to be tilted to the right, the paddle 29 and the supporting frame 25 are designed as a rotating structure, the second electric push rod 30 and the paddle 29 are designed as a rotating structure, the bottom of the second electric push rod 30 is hinged on the supporting frame 25, and the second electric push rod 30 and the supporting frame The frame 25 is designed as a rotating structure. When the riding mode is selected, the customer can sit on the seat 26 and step on the pedal 28 to rotate the driving wheel 27 to drive the shopping cart. When the shopping cart moves to the restricted area of ​​the supermarket, the electronic tag sensor 16 senses the electronic tag and transmits the signal to the tablet computer 14 through the control box 11. After processing by the tablet computer 14, the signal is transmitted to the control box 11 to control the second electric push rod 30 to push upward, so that the paddle 29 rotates and engages with the teeth welded on the inner ring of the driving wheel 27. Since the teeth are tilted to the right, the shopping cart can only move forward and cannot move backward, which effectively prevents the shopping cart from being pushed out of the supermarket by customers, making it difficult to organize and reducing the labor intensity of the staff.

[0037] Working principle: During operation, staff will install electronic tags in various restricted areas of the supermarket in advance to monitor and restrict shopping carts.

[0038] During use, the staff can loosen the threaded rod 23 by turning the nut sleeved at the bottom of the threaded rod 23 to separate the connecting rod 24 from the base 18. According to the customer's choice, the staff can flexibly adjust whether to install the connecting rod 24. When the connecting rod 24 is installed on the left side of the base 18, the customer can sit on the seat 26 and step on the pedal 28 to drive the driving wheel 27, so that the shopping cart can be ridden. The ultrasonic detector 2 installed at the right end of the shopping cart basket 1 can sense pedestrians in front of the shopping cart and transmit the sensed signal to the tablet computer 14 through the control box 11. The tablet computer 14 processes and analyzes the signal to remind the customer who uses the shopping cart.

[0039] When in use, a supermarket APP is installed inside the tablet computer 14, and the tablet computer 14 is connected to the supermarket network via WiFi, and the commodity information inside the supermarket is presented on the tablet computer 14 for customers to search. The staff can know the partition location of the corresponding commodity through the search. When in use, the customer can rotate it downward so that the seat cushion 8 is placed on the seat support plate 5. Under the elastic support of the second spring 7, the latch 6 keeps rotating upward, and the position of the seat cushion 8 is restricted and locked to prevent the seat cushion 8 from moving and shrinking during use. At the same time, when a child sits on the seat cushion 8, the first pressure detector 10 on the seat cushion 8 elastically supported by the third spring 9 can sense the presence of the child and transmit the sensing signal It is handed to the control box 11. The human infrared detector 13 installed in the middle position on the left side of the support rod 12 can sense whether there is an adult customer and transmit the sensed signal to the control box 11. The control box 11 transmits the signals of the first pressure detector 10 and the human infrared detector 13 to the tablet computer 14, which analyzes and processes them. If the first pressure detector 10 senses the presence of a child and the human infrared detector 13 cannot sense an adult, the tablet computer 14 will issue a sound warning. If the human infrared detector 13 still cannot sense the presence of an adult customer 10s after the first pressure detector, the tablet computer 14 will transmit the signal to the supermarket staff via WiFi to remind the staff to handle it.

[0040] When a customer rides the shopping cart to the edge of the restricted area, the electronic tag sensor 16 installed at the bottom of the shopping cart basket 1 senses the electronic tag attached to the restricted area of ​​the supermarket. The electronic tag sensor 16 transmits the signal to the tablet computer 14 through the control box 11. After processing by the tablet computer 14, the tablet computer 14 sends a control signal to the control box 11. The control box 11 controls the second electric push rod 30 to push up, so that the paddle 29 hinged on the second electric push rod 30 rotates and engages with the teeth welded on the inner ring of the drive wheel 27, fixing the drive wheel 27 so that the shopping cart cannot continue to move forward. When the shopping cart moves, the electronic tag sensor 16 installed at the bottom of the shopping cart basket 1 can detect the change in the distance of the electronic tag in the restricted area, and transmit the signal to the tablet computer 14 through the control box 11. After analysis and processing by the tablet computer 14, if the distance between the two previous and subsequent detections becomes closer, the tablet computer 14 will issue an alarm and control the second electric push rod 30 to continue to push upward, so that the drive wheel 27 is locked. If the distance between the two previous and subsequent detections is far, the tablet computer 14 will cancel the alarm and control the second electric push rod 30 to retract downward, so that the drive wheel 27 is unlocked and the shopping cart can continue to be ridden.

[0041] When the goods inside the shopping cart basket 1 are placed unbalanced, the second pressure detector 21 installed below the corresponding position can sense the pressure change at the corresponding position and send a signal to the tablet computer 14 through the control box 11. The tablet computer 14 processes and analyzes the signal, warns the customer, and reminds the customer to make adjustments. If the customer does not make any adjustments within 10 seconds after the first pressure detector is detected, the tablet computer 14 sends an instruction to the control box 11 to control the first electric push rod 19 at the corresponding position to push upward, so that the inside of the shopping cart basket 1 returns to a safe position, or the goods in the shopping cart basket 1 are automatically adjusted due to the tilt of the shopping cart basket 1. When the customer finishes selecting the goods, the customer can use the barcode scanner 15 to scan the code to check out through the supermarket APP built into the tablet computer 14, and make online payments through the tablet computer 14.
