Detailed Implementation

[0034] To provide a clearer understanding of the technical features, objectives, and effects of this disclosure, specific embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0035] Implementation Method 1

[0036] As shown in Figures 1 to 10, this embodiment of the present disclosure provides a shopping checkout device, which includes a smart shopping device 1, a base assembly 2, and a locking structure for locking the assembly positions of the smart shopping device 1 and the base assembly 2. The smart shopping device 1 can be used for at least merchandise checkout. The base assembly 2 is detachably mounted on a shopping cart. The top of the base assembly 2 has a mounting groove 2021 that matches the smart shopping device 1, and the bottom of the smart shopping device 1 is inserted into the mounting groove 2021. When the bottom of the smart shopping device 1 is inserted into a preset position in the mounting groove 2021, the locking structure locks the relative position of the smart shopping device 1 and the base assembly 2. Only when the smart shopping device is in the locked state can it be turned on or enter a normal working state.

[0037] The aforementioned preset position can be the location where the bottom wall of the mounting slot 2021 contacts the bottom of the smart shopping device 1. At this position, the smart shopping device 1 is securely inserted into the mounting slot 2021, ensuring good stability of the smart shopping device 1 on the shopping cart during shopping. Of course, the aforementioned preset position can also be set according to the actual connection structure.

[0038] In this disclosure, the base assembly 2 is detachably mounted on the shopping cart. The base assembly 2 is provided with a cylindrical mounting groove 2021 with a top opening. The bottom of the smart shopping device 1 can be inserted into the mounting groove 2021 through the top opening, realizing convenient installation of the smart shopping device 1 on the shopping cart. Since a locking structure is provided between the smart shopping device 1 and the base assembly 2, when the bottom of the smart shopping device 1 is inserted into the preset position in the mounting groove 2021, the locking structure locks the relative position of the smart shopping device 1 and the base assembly 2. At this time, the smart shopping device 1 can be turned on or enter the normal working state, ensuring that the smart shopping device 1 can perform normal product checkout, smart shopping device 1 positioning, and product information push functions, ensuring stable installation of the smart shopping device 1 and normal use by customers during the shopping process, greatly improving shopping efficiency and shopping experience.

[0039] This disclosure provides a cost-effective and easy-to-implement intelligent shopping checkout device for the supermarket industry. It not only meets the needs of efficient and convenient self-service scanning and checkout, but also has functions such as product navigation and positioning, product identification and weighing, targeted product push, and anti-theft and damage prevention. It can greatly improve customers' shopping efficiency and shopping experience, and solve the key issues of cost and security.

[0040] In an optional embodiment of this disclosure, as shown in Figures 1 to 3, 5, and 7, the base assembly 2 includes a support frame 201 and a base body 202. The support frame 201 is a plate-like structure located between the crossbeam handle 20 and the shopping basket crossbeam 30 of the shopping cart. The support frame 201 has a first end and a second end (i.e., the two ends of the support frame 201). The first end of the support frame 201 is used to be detachably connected to the crossbeam handle 20 of the shopping cart, and the second end of the support frame 201 is used to be detachably connected to the shopping basket crossbeam 30 of the shopping cart. Thus, the smart shopping device 1 can be externally installed with the shopping cart through the base assembly 2.

[0041] Furthermore, as shown in Figures 2 and 3, the base body 202 is disposed on the top of the support frame 201. The base body 202 has a cylindrical structure with an open top, forming a mounting groove 2021. The bottom of the smart shopping device 1 has a plug-in part 101 that matches the mounting groove 2021. The plug-in part 101 is inserted into the mounting groove 2021, thereby ensuring the stable assembly of the smart shopping device 1 and the base assembly 2. In addition to the mounting groove 2021 being compatible with the smart shopping device 1, smart devices such as smartphones or PDAs can also be inserted obliquely into the mounting groove 2021 on the base body 202, satisfying customers' diverse choices of smart devices and providing stronger adaptability.

[0042] Furthermore, as shown in Figures 1 to 3, the first end of the support frame 201 is provided with an openable hinge 2011, which is fitted onto the crossbeam handle 20 of the shopping cart. The opening of the hinge 2011 is connected by screws. The second end of the support frame 201 is provided with a retractable support leg 2012. The front end of the support leg 2012 is provided with a slot that matches the crossbeam 30 of the shopping cart, so that at least part of the outer wall of the crossbeam 30 of the shopping cart is engaged in the slot. During installation, the first end of the support frame 201 is pre-installed onto the crossbeam handle 20 of the shopping cart using the hinge 2011, and the hinge 2011 is fixed with screws. Then, the length of the support leg 2012 is adjusted so that at least part of the outer wall of the crossbeam 30 of the shopping cart is engaged in the slot at the front end of the support leg 2012. By fixing at two points, the base assembly 2 is prevented from rotating around the crossbeam handle 20. The base assembly 2 is secured entirely by the existing structure of the shopping cart, without adding to or altering its structure, thus achieving simple and convenient installation. Each installation only requires tightening the screws on the hinge 2011 to complete the installation of the base assembly 2 onto the shopping cart. The installation and removal processes do not damage the shopping cart, and the structure is stable and reliable.

[0043] Specifically, as shown in Figures 1 to 3, the telescopic structure of the support leg 2012 is as follows: A limiting groove extending in the front-to-back direction is located at the second end of the support frame 201. The rear end of the support leg 2012 can slide back and forth within the limiting groove. The support leg 2012 and the second end of the support frame 201 can be connected by screws. By adjusting the position of the rear end of the support leg 2012 within the limiting groove, the length of the support leg 2012 extending out of the limiting groove can be adjusted. The telescopic support leg 2012 allows the base assembly 2 to be adapted to connection points of different distances, enhancing its adaptability to different shopping cart models. It can accommodate different lengths between the shopping cart's crossbeam handle 20 and the shopping basket's crossbeam 30 without requiring special customization of the base assembly 2.

[0044] Multiple threaded holes can be arranged side-by-side along the front-rear direction on the support leg 2012 and the second end of the support frame 201. By adjusting the positional relationship between the support leg 2012 and the second end of the support frame 201, the required length of the support leg 2012 extending out of the limiting groove can be adjusted. At this time, the threaded holes on the support leg 2012 are connected to the threaded holes at corresponding positions on the second end of the support frame 201. Screws are screwed into the two connected threaded holes respectively to lock the extension and retraction position of the support leg 2012. This adjustment method for the support leg 2012 is a graded adjustment (that is, the support leg 2012 can be adjusted to multiple preset lengths). It is suitable for several shopping carts where the distance between the crossbeam handle 20 and the shopping basket crossbeam 30 is known. Thus, the length of the support leg 2012 can be adjusted by the position of the preset threaded holes.

[0045] Alternatively, a threaded hole can be provided on one of the second ends of the support leg 2012 and the support frame 201, and a waist-shaped hole extending in the front-rear direction can be provided on the other. Preferably, the waist-shaped hole is provided on the second end of the support frame 201, while the threaded hole is provided on the support leg 2012. The extension length of the support leg 2012 can be adjusted according to the distance between the shopping cart's crossbeam handle 20 and the shopping basket crossbeam 30. Then, a screw is passed through the waist-shaped hole and screwed into the threaded hole to lock the extension position of the support leg 2012. This adjustment method for the support leg 2012 is stepless (that is, the length of the support leg 2012 can be adjusted at any position within the range of the waist-shaped hole), making the adjustment more flexible and suitable for shopping carts with any distance between the shopping cart's crossbeam handle 20 and the shopping basket crossbeam 30. The waist-shaped hole allows the screw to move within the waist-shaped hole during position adjustment, achieving the purpose of adjustable length of the support leg 2012.

[0046] The base component 2 disclosed herein, when installed on the shopping cart, will not affect the normal use of the shopping cart or its cascading with other shopping carts (e.g., when multiple shopping carts are to be recycled, multiple shopping carts can be inserted sequentially in a row). The shopping cart can work normally and be recycled, which can greatly save space.

[0047] Furthermore, as shown in Figure 3, a limiting groove 2022 is provided on the inner wall of the mounting groove 2021. The limiting groove 2022 can be a groove located on the inner wall of the mounting groove 2021 and extending along the insertion direction of the smart shopping device 1. When the bottom of the smart shopping device 1 is inserted into the mounting groove 2021, at least a part of the smart shopping device 1 can be slidably embedded in the mounting groove 2021 to achieve the function of guiding the installation of the smart shopping device 1 and ensuring the accurate positioning of the smart shopping device 1 and the mounting groove 2021.

[0048] In an optional embodiment of this disclosure, as shown in Figures 3 and 5, positioning detection elements 2023 are respectively provided at at least two positions in the mounting groove 2021. The smart shopping device 1 is provided with a trigger element 102 that cooperates with the positioning detection elements 2023. When the bottom of the smart shopping device 1 is inserted into a preset position within the mounting groove 2021, the trigger element 102 can trigger the positioning detection elements 2023 at the corresponding positions. The positioning detection elements 2023 can be, but are not limited to, Hall effect detection elements (such as Hall sensors), and the trigger element 102 can be, but is not limited to, a detection magnet. Furthermore, the positioning detection elements 2023 are positioned on the bottom wall and side wall of the mounting groove 2021, respectively. Of course, the number of positioning detection elements 2023 can also be two or more, but at least one positioning detection element 2023 must be provided on the bottom wall and side wall of the mounting groove 2021, respectively, to simultaneously detect the smart shopping device 1 being installed in place at two different positions. The specific positions on the bottom wall and side wall of the mounting groove 2021 are not limited here.

[0049] In an optional embodiment of this disclosure, as shown in Figures 3, 5, 7, and 8, the locking structure includes a spring block 2024 and a push rod 104. The inner wall of the mounting groove 2021 has a first positioning hole 2025. The spring block 2024 is located inside the first positioning hole 2025, and the top of the spring block 2024 extends out of the first positioning hole 2025. The bottom of the smart shopping device 1 is provided with a second positioning hole 103 communicating with its interior. The push rod 104 is telescopically disposed in the second positioning hole 103. When the bottom of the smart shopping device 1 is inserted into a preset position in the mounting groove 2021, the push rod 104 retracts into the second positioning hole 103, and at least a portion of the spring block 2024 extends into the second positioning hole 103, so that the smart shopping device 1 is turned on or enters a normal working state.

[0050] Furthermore, the push rod 104 is an electrically controlled push rod that is driven by a motor, thereby realizing the automatic extension and retraction movement of the push rod 104 according to the control command.

[0051] According to the above structure, this disclosure enables automatic locking and unlocking between the smart shopping device 1 and the base assembly 2. During the customer's shopping process, after removing the smart shopping device 1 from the charging station, its bottom is inserted into the mounting slot 2021 on the base assembly 2. During the insertion process, the push rod 104 retracts into the second positioning hole 103, so that the second positioning hole 103 has some free space. After the bottom of the smart shopping device 1 is inserted into the preset position, the spring pressure block 2024 is located in a position opposite to the second positioning hole 103, so that at least a part of the spring pressure block 2024 can extend into the second positioning hole 103 to achieve locking. In the above process, only when both Hall effect sensors detect the signals of the two detection magnets at their corresponding positions is the smart shopping device 1 considered to be properly assembled with the base assembly 2. At this time, the drive push rod 104 retracts into the second positioning hole 103, which has some empty space. The spring block 2024 on the base body 202 pops out and extends into the empty space of the second positioning hole 103, achieving a locking state. At this time, the smart shopping device 1 is considered to be properly assembled, and it can then be started or proceed with the normal shopping process. If only one Hall effect sensor detects the signal of one of the detection magnets or no signal is detected, the smart shopping device 1 is considered not properly assembled. The smart shopping device 1 can then indicate a locking abnormality for inspection. In this case, the push rod 104 does not move (remains in an extended state) to prevent it from jamming and causing damage. The smart shopping device 1 will not start the normal shopping process until it is properly installed.

[0052] In this disclosure, by setting up two Hall effect detection elements and corresponding detection magnets, it is possible to effectively prevent the device from being accidentally locked (i.e., the smart shopping device 1 and the base assembly 2 are not properly assembled), thus avoiding the situation where the smart shopping device 1 slips off and is damaged during shopping.

[0053] In one optional embodiment of this disclosure, the support frame 201 may be made of, but is not limited to, metal materials, wherein the support frame 201 may be made of, but is not limited to, extruded aluminum alloy; the base body 202 may be made of, but is not limited to, plastic. The base assembly 2 is made entirely of a combination of metal and plastic. The metal support frame 201 has better strength and stability, more precise dimensions, and meets IP54 requirements, while the plastic base body 202 is easier to manufacture and process, suitable for compatibility with different smart shopping devices 1, and can save production costs.

[0054] In an optional embodiment of this disclosure, as shown in FIG5, the smart shopping device 1 includes a housing 118, a display screen 105 disposed on the top of the housing 118, and a plug-in portion 101 located at the bottom of the housing 118; a pluggable barcode scanner 108 is disposed at the bottom of the housing 118, and the barcode scanner 108 is connected to the housing 118 via a retractable spring cable, increasing the range of motion and flexibility of the barcode scanner 108, allowing customers to conveniently scan barcodes from different positions and angles, which is particularly suitable for scanning heavy or large items. The display screen 105 may be, but is not limited to, a 10-inch LCD display screen, and can be used to display data and information such as product checkout, location tracking of the smart shopping device 1, and product information push notifications.

[0055] Furthermore, a magnetic locking structure is provided between the barcode scanner 108 and the bottom of the housing 118 to fix the barcode scanner 108 to the bottom of the housing 118. This improves the flexibility and ease of use of the barcode scanner 108, allowing it to be quickly installed and disassembled to adapt to different usage scenarios.

[0056] This disclosure employs a retractable, pluggable barcode scanner 108, suitable for scanning the barcodes of goods of different sizes and types (including paperless purchases of bulk fresh produce). It supports paperless purchasing, reducing paper usage during the shopping process and aligning with environmental trends. The scanner 108 is integrated into the smart shopping device 1, powered by an internal battery. It can be disassembled and charged along with the smart shopping device 1, reducing the number of power supplies and cables, eliminating the need for a separate power supply and redundant wiring, simplifying the device structure, increasing integration, and improving ease of use and aesthetics. In addition, the barcode scanner 108 disclosed herein can provide customers with two scanning methods ("item scanning" and "code scanning item"). For heavier items that are difficult to lift, customers can first pull out the barcode scanner 108 to scan the items on the shelf and then put the items into the shopping cart; or they can put the items into the shopping cart first and then pull out the barcode scanner 108 to scan the items. After the customer completes the scanning with the barcode scanner 108, the scanned items will be automatically transferred to the shopping list in the shopping software pre-installed in the smart shopping device 1, which facilitates quick checkout, reduces waiting time at checkout, and improves shopping efficiency.

[0057] In one optional embodiment of this disclosure, an NFC communication module is provided on the inner side of the display screen 105. Customers can log in to the member account in the preset software of the smart shopping device 1 by scanning a code with the barcode scanner 108 or swiping a card with the NFC communication module. The member account can be bound with the information of the logged-in user.

[0058] In an optional embodiment of this disclosure, as shown in FIG6, a broadband communication module 109, a narrowband communication module 110, and a nine-axis sensor 111 are disposed within the housing 118. Through the cooperation of the broadband communication module 109, the narrowband communication module 110, and the nine-axis sensor 111, indoor positioning of the shopping cart, location tracking of the smart shopping device 1, and the deployment of electronic fences can be achieved to prevent theft of goods. Broadband communication has the advantages of stable signal and high speed, and can be used for overall communication during the shopping process; while narrowband communication not only assists the shopping cart in indoor positioning calibration, but more importantly, because the narrowband communication module 110 has an additional battery for separate power supply, even after the smart shopping device 1 is powered off, the narrowband communication module 110 can still continuously communicate with the indoor base station, ensuring that the smart shopping device 1 is always located within the store, effectively achieving real-time positioning and tracking of the offline smart shopping device 1; in addition, the narrowband communication module 110 can be combined with the indoor base station to deploy electronic fences indoors using methods such as angle of arrival (AOA) or triangulation, without... In cases where the normal communication and IP address of the broadband communication module 109 are affected, the functional permissions of the smart shopping device 1 in a preset specific area indoors can be controlled through an electronic fence. For example, the smart shopping device 1 can only enter the product checkout process when the shopping cart reaches the preset checkout area (the checkout area limited by the electronic fence), thereby preventing theft of the shopping cart after checkout inside the store. Another example is that when the smart shopping device 1 reaches a specific promotional area indoors, the coupons in the software can be activated and used, thereby realizing the interaction between the offline store and the LED light strip set on the smart shopping device 1 can provide reminders through color changing or flashing.

[0059] In an optional embodiment of this disclosure, as shown in FIG6, at least two second cameras 106 are disposed on the outer casing 118 facing the shopping basket of the shopping cart, with the two second cameras 106 located on the left and right sides of the outer casing 118, respectively; as shown in FIG5, a first camera 107 is disposed on the outer casing 118 above the barcode scanner 108. The smart shopping device also includes a weight sensor 40, which is disposed at the bottom of the shopping basket of the shopping cart. In addition, as shown in FIG4 and FIG5, a speaker 115 and a microphone 116 are disposed on the outer casing 118, and an LED strip 117 is disposed on the outer casing 118.

[0060] The two second cameras 106 have multiple operating modes to suit different shopping scenarios. For example, when both second cameras 106 work simultaneously, they can monitor different areas within the shopping cart's basket, ensuring comprehensive coverage and preventing purchased items from entering the basket through blind spots. The single-camera-106 mode primarily operates when the other is obstructed or when the smart shopping device 1's battery is low and it switches to energy-saving mode. When the smart shopping device 1 is in energy-saving mode, the two second cameras 106 will determine the optimal operating mode based on factors such as lighting and recognition accuracy, selecting the camera with better lighting and recognition accuracy to operate, while the other camera 106 will remain inactive.

[0061] The first camera 107 is used to identify the scanning area. The product information identified by the barcode scanner 108 can be compared with the product feature information captured by the first camera 107, the product feature information captured by the second camera 106, and the information fed back by the weight sensor 40 when weighing the product. When the similarity of the comparison reaches a preset threshold, the selected product can be determined and added to the shopping list.

[0062] In the above process, after a customer selects an item from among several items closest to their desired product pushed by the smart shopping device 1, the shopping cart's location can be assisted by the broadband communication module 109, the narrowband communication module 110, and the nine-axis sensor 111 to determine whether the area where the customer's selected item is located matches the actual sales area of ​​the selected item. Furthermore, by analyzing the shopping cart's movement path and stopping area, corresponding items in the product database can be extracted and compared, accelerating the comparison efficiency between the feature information of the scanned items and the feature information of the items actually placed in the shopping cart. Simultaneously, the confidence level of an item can be judged by verifying the reasonableness of its appearance in the identified location area. Through these methods, the theft rate using the shopping cart channel is reduced, achieving the goal of preventing product theft.

[0063] Furthermore, as shown in Figure 6, a battery 113 is provided inside the outer casing 118, and a charging interface 114 connected to the power supply terminal of the battery 113 is provided at the bottom of the outer casing 118; a computing module 112 is provided inside the outer casing 118, which can at least perform product settlement, location of the smart shopping device 1, and product information push. The computing module 112 can be pre-set with corresponding application software to realize the above-mentioned functions such as product settlement, location of the smart shopping device, and product information push.

[0064] This disclosed shopping checkout device can be used by users (customers) for shopping payments, and can also be used by store staff. Specifically:

[0065] The shopping checkout device disclosed herein can be used as a picking assistant. It records product inventory and order information in the preset software of the smart shopping device 1 and displays this information on the display screen 105. This allows staff to pick products based on the inventory and order information. During the picking process, the display screen 105 shows the location of the products to be picked and the optimal path, enabling staff to quickly and accurately locate the corresponding products and complete the order picking. If unauthorized picking behavior is detected, alerts and warnings can be issued via components such as the light strip 117 and speaker 115 on the smart shopping device 1, notifying staff to handle the situation promptly.

[0066] In addition, the first camera 107, the second camera 106 and / or the barcode scanner 108 on the smart shopping device 1 can scan the barcode or identify the image information of the goods to ensure the accuracy of the goods picking. At the same time, the weight sensor 40 verifies the weight of the picked goods to prevent the picking of goods from being wrong or missing.

[0067] The shopping checkout device disclosed herein can also monitor the quantity of goods on the shelves using the first camera 107 and / or the second camera 106. When the quantity of goods in a preset area falls below a preset quantity threshold, an alert signal can be emitted via the light strip 117 or the display screen 105 so that staff can replenish the stock in a timely manner. Furthermore, based on sales data and user purchase quantities, the device can preset the replenishment time and / or quantity of corresponding goods to avoid stockouts and achieve more effective inventory management.

[0068] The shopping checkout device disclosed herein can also be used for training and operational guidance of new employees. For example, the smart shopping device 1 can be equipped with built-in training software or training processes, and a virtual training module can be provided to new employees through the display screen 105 (used to teach the correct methods of picking, replenishing and inventory management; for complex or uncommon product operations, the display screen 105 can display relevant operation steps or video tutorials to help employees quickly master the correct product operation procedures).

[0069] The specific usage and operation procedures of the shopping checkout device disclosed herein are as follows:

[0070] 1. Unlocking Smart Shopping Device 1 from the Charging Wall (Power Supply Location) at the Supermarket Entrance: After logging into their account at the charging location via QR code or NFC card swipe, the user can start the shopping process or unlock Smart Shopping Device 1. At this time, the locking device between Smart Shopping Device 1 and the power supply wall opens, allowing Smart Shopping Device 1 to be removed from the power supply location. The opening process of the locking device can be achieved by pushing the push rod 104 inside Smart Shopping Device 1 from the inside out until it is flush with the wall surface of Smart Shopping Device 1, thereby disengaging the locking device between Smart Shopping Device 1 and the power supply wall and unlocking it. The specific structure of the locking device and the specific locking and unlocking process between Smart Shopping Device 1 and the power supply wall are not limited here.

[0071] 2. The user connects the smart shopping device 1 to the base assembly 2 on the shopping cart: After the user removes the smart shopping device 1 from the charging wall, the end of the push rod 104 inside the smart shopping device 1 is flush with the wall surface of the smart shopping device 1, allowing the smart shopping device 1 to be easily inserted into the mounting slot 2021 on the base assembly 2. After the bottom of the smart shopping device 1 is properly assembled with the base assembly 2, the trigger element 102 on the smart shopping device 1 identifies the positioning detection element 2023 on the base assembly to confirm that the smart shopping device 1 and the base assembly 2 are properly assembled and then lock them together. The locking process involves the push rod 104 inside the smart shopping device 1 retracting inward into the second positioning hole 103, and the compressed spring block 2024 on the inner wall of the mounting slot 2021 of the base assembly 2 returning to its original length and extending at least partially into the second positioning hole 103, thus achieving locking. If the smart shopping device 1 is not properly assembled with the base assembly 2, the trigger element 102 cannot identify the positioning detection element 2023, nor can it confirm the position and status of the smart shopping device 1. At this time, the push rod 104 will not move, and the smart shopping device 1 will display relevant information on the display screen 105 to remind the user to install the smart shopping device 1 properly to prevent the device from falling.

[0072] 3. The user removes the smart shopping device 1 from the base assembly 2: After the user finishes shopping and checking out, they can click on the corresponding area on the display screen 105 (e.g., the area displaying "Change Car"). At this time, the locking structure of the smart shopping device 1 is activated, and the push rod 104 extends from the inside to its maximum stroke. At this point, the end of the push rod 104 is flush with the wall surface of the smart shopping device 1, and the compression spring block 2024 moves out of the second positioning hole 103. The smart shopping device 1 is unlocked from the base assembly 2, and the user can remove the smart shopping device 1 from the base assembly 2.

[0073] IV. The user places the smart shopping device 1 into the transfer recycling cart or back into the charging wall: After removing the smart shopping device 1 from the base assembly 2, it can be placed into the base of the transfer recycling cart or the charging base of the charging wall at the supermarket exit. At this time, the push rod 104 on the smart shopping device 1 is flush with the wall surface of the smart shopping device 1. After the smart shopping device 1 is placed in place, the trigger element 102 on the smart shopping device 1 can match and identify the position detection element preset on the base of the transfer recycling cart or the charging wall. After confirming that the smart shopping device 1 and the charging base of the transfer recycling cart or the charging wall are assembled in place, the two can be locked together through a preset locking position. During the locking process, the push rod 104 on the smart shopping device 1 retracts inward into the second positioning hole 103, and part of the locking device at the corresponding position of the charging base of the transfer recycling cart or the charging wall can extend into the second positioning hole 103 to achieve locking. If the smart shopping device 1 is not properly installed on the base of the transfer recycling vehicle or the charging base of the charging wall, the trigger element 102 cannot identify the positioning detection element, nor can it confirm the position and status of the smart shopping device 1. At this time, the push rod 104 will not move, and the smart shopping device 1 will display relevant information on the display screen 105 to remind the user to install the smart shopping device 1 properly to prevent the device from falling.

[0074] At this point, the entire shopping process is complete.

[0075] The features and advantages of this shopping checkout device are:

[0076] First, this shopping checkout device features a detachable and compatible design. It is designed as a detachable and rechargeable smart shopping device 1 assembled with a base component 2, allowing for quick and easy installation on any existing standard shopping cart. This enables rapid assembly and replacement of the checkout device without altering the original structure of the shopping cart, while simultaneously reducing the one-time investment costs for merchants.

[0077] Second, the shopping checkout device has stronger adaptability and integration. It adopts a design that combines a metal support frame 201 and a plastic base body 202. The support frame 201 is telescopic and can be adapted to shopping carts of various sizes. Furthermore, the support frame 201 is detachably connected to the shopping cart using a hinge 2011 and a slot fixing method, which ensures a stable installation without damaging the shopping cart.

[0078] Third, the shopping checkout device has locking and security features. It uses a locking structure and a positioning detection element 2023 to locate the assembly position of the base assembly 2 and the smart shopping device 1, and achieves a secure lock after positioning to ensure that the smart shopping device 1 will not accidentally slip during use, while also providing anti-theft and anti-damage capabilities.

[0079] Fourth, the shopping checkout device has a false lock protection mechanism. The assembly position of the smart shopping device 1 is detected by two positioning detection elements 2023 at different locations to avoid false locks or damage to the device caused by incorrect device positioning, thus ensuring the normal operation of the device and the safe use by customers.

[0080] Fifth, the shopping checkout device realizes user interaction and functional integration. The base component 2 not only supports the assembly of the smart shopping device 1, but is also compatible with the insertion of smart devices such as smartphones or PDAs, providing a variety of operation options. The setting of the mounting slot 2021 on the base body 202 increases the stability of the assembly and reduces the risk of the smart shopping device 1 slipping due to external factors.

[0081] VI. In this shopping checkout device, the intelligent shopping device 1 has broadband and narrowband communication capabilities, as well as anti-theft and anti-damage capabilities, barcode scanning, indoor positioning, and information push (such as advertising). All kinds of information can be displayed on the display screen 105. The intelligent shopping device 1 is detachable and rechargeable, and can be installed on any type of shopping cart with the base component 2. It can realize the intelligence of the shopping cart without changing the original structure of the shopping cart, effectively improving the customer's shopping experience. At the same time, it can act as a shopping assistant for customers, providing them with more personalized, flow map-based, and promotional area-targeted product recommendations and advertising. In addition, through positioning and the acquisition and monitoring of product information, it can be used to analyze the customer's shopping process and behavior in the store, providing merchants with effective operational strategy recommendations and optimization guidance.

[0082] Implementation Method 2

[0083] This disclosure provides a shopping cart, which includes a shopping cart body 10 and the aforementioned shopping checkout device. The shopping cart body 10 includes a shopping cart basket and a crossbeam handle 20. The shopping checkout device is detachably connected to the shopping cart basket crossbeam 30 and the crossbeam handle 20.

[0084] In this disclosure, the main body 10 of the shopping cart is the existing shopping cart body, and no structural changes are made to the main body 10 of the shopping cart.

[0085] The shopping cart disclosed herein has the same features and advantages as the aforementioned shopping checkout device, which will not be repeated here.

[0086] Implementation Method 3

[0087] This disclosure provides a smart shopping method that uses the aforementioned shopping checkout device for checkout. The smart shopping method includes the following steps:

[0088] Step S1: Connect the smart shopping device 1 to the base component 2 pre-installed on the shopping cart;

[0089] The bottom of the smart shopping device 1 is inserted into the mounting slot 2021 of the base assembly 2. When the bottom of the smart shopping device 1 is inserted into the preset position in the mounting slot 2021, the locking structure between the smart shopping device 1 and the base assembly 2 locks the relative position of the smart shopping device 1 and the base assembly 2.

[0090] Step S2: The smart shopping device 1 is turned on or enters normal working state to perform product checkout, locate the smart shopping device 1, and push product information.

[0091] In one optional embodiment of this disclosure, before step S1, the smart shopping device 1 is preset in the power supply position. The smart shopping device 1 can only be removed from the power supply position after logging into a personal account via the smart shopping device 1. Specifically, a locking device is provided between the power supply position and the smart shopping device 1. After logging into the personal account, the locking device is opened, allowing the smart shopping device 1 to be removed from the power supply position.

[0092] In this disclosure, users need to log in to their personal accounts through smart shopping device 1 to obtain their prior shopping information and receive related shopping information push notifications. This synchronization mechanism not only enhances the personalized shopping experience but also improves data-driven operational efficiency. The pushed shopping information includes personal shopping coupon information, personal shopping credit rating information, product recommendations and promotional information, shopping lists, etc. Of course, other information can also be pushed according to merchant or user needs; this disclosure does not limit the specific information pushed.

[0093] Furthermore, personal accounts include member accounts and non-member accounts. During the shopping process, the smart shopping device 1 uses a higher detection standard for abnormal shopping behavior of non-member accounts than for member accounts. When a non-member account is used to log in or when the detected abnormal shopping behavior exceeds a preset threshold, the smart shopping device 1 issues an early warning. This implements a dynamic security and loss prevention mechanism, automatically adjusting the user's integrity level based on login history and shopping behavior analysis. By detecting and managing abnormal user shopping behavior, if the smart shopping device 1 detects frequent failed login attempts due to abnormal shopping behavior, it will refuse login and prompt the user to contact staff, increasing the effectiveness of theft prevention and accidental operation prevention.

[0094] The specific login process is as follows: After entering the supermarket store, customers can log in to their personal account (member account or non-member account) in the preset software of the smart shopping device 1 by scanning a code with the barcode scanner 108 on the smart shopping device 1 or by swiping a card using the NFC communication module on the smart shopping device 1. The member account is bound to the user's personal information. The above login process and the user's personal information data can be synchronized with the supermarket's cloud system. During operation, the product recommendations and promotional information in the built-in software of the smart shopping device 1 can be quickly updated through the broadband communication module 109 and the narrowband communication module 110 (which can be customized to update and push product information according to different users' shopping habits and shopping categories). At the same time, the user's personal shopping coupon information, credit rating information, shopping list information and other usage data are displayed to help determine the usage status of the smart shopping device 1 before entering shopping mode. When a logged-in member account has more than a preset threshold of abnormal shopping behavior (such as unsettled purchases, discrepancies between items placed in the shopping cart and those to be checked out, or selected items appearing in areas not corresponding to the item), or when abnormal shopping behavior causes the user's integrity level to fall below a preset level, the pre-installed software in the smart shopping device 1 will be unable to log in normally, and the smart shopping device 1 will be unable to be turned on or used normally. At this time, the light strip 117 on the smart shopping device 1 will light up red, and the display screen 105 will prompt the user to contact supermarket staff for assistance. Of course, the smart shopping device 1 can also be turned on or used normally by non-members, but the sensitivity to detecting abnormal behavior during the user's shopping process will be increased. Furthermore, after the purchase is completed and checked out, the light strip 117 on the smart shopping device 1 will light up red to remind staff to verify the shopping bill, thus achieving a certain degree of anti-theft and loss prevention effect. In addition to the login methods mentioned above, users can also log in to their personal accounts by entering a member code and personal identification information (such as a mobile phone verification code) on the display screen 105. For users with poor eyesight (such as those with presbyopia), the device can also interact with the user through the speaker 115 and microphone 116 to log in.

[0095] The disclosed smart shopping method employs diverse identity verification and login methods, including barcode scanning, NFC card swiping, manual input of member codes, and visual and voice-assisted input, enabling users with different needs and abilities to conveniently use the smart shopping device 1 for shopping, especially providing greater convenience for users with visual impairments. The login process considers user experience, ensuring fast and secure login to personal accounts, allowing users to smoothly and naturally transition to shopping mode. Through simplified login steps and instant feedback, users can enter the shopping process more quickly.

[0096] In an optional embodiment of this disclosure, the smart shopping method further includes, during the shopping process, using a second camera 106 to collect first product information of the shopping basket already placed in the shopping cart, using a first camera 107 to collect second product information of the product taken by the user but not yet placed in the shopping basket, and using a barcode scanner 108 to collect third product information of the product taken by the user but not yet placed in the shopping basket. The first product information, the second product information, and the third product information are compared to determine whether the product scanned by the barcode scanner 108 is the same product as the product taken by the user and placed in the shopping basket of the shopping cart, thereby achieving the purpose of preventing theft and damage.

[0097] In another optional embodiment of this disclosure, the smart shopping method further includes, during the shopping process, collecting fourth product information of the products in the shopping basket to be placed in the shopping cart by a weight sensor 40 set at the bottom of the shopping basket, and comparing the first product information, the second product information, the third product information and the fourth product information to determine whether the product scanned by the barcode scanner 108 is the same product as the product taken and placed in the shopping basket of the shopping cart.

[0098] The first product information includes packaging form information, packaging color information, and pattern information on the product packaging, all captured by the second camera 106. The second product information includes packaging form information, packaging color information, and pattern information on the product packaging, all captured by the first camera 107. Of course, the first and second product information can also be image information of other products that can be captured by the cameras.

[0099] The third product information includes the corresponding product information obtained by the barcode scanner 108 by scanning the barcode on the product packaging; the fourth product information includes the weight information of the product.

[0100] When comparing the first, second, third, and fourth product information, it is necessary to find the product corresponding to the first, second, and fourth product information in the product database with pre-stored product information, and then compare whether the product matches the third product information, so as to determine whether the first, second, third, and fourth product information correspond to the same product.

[0101] In actual shopping, theft and damage of goods have always been pain points in offline retail, and most existing handheld barcode scanners lack anti-theft and anti-damage capabilities. To address this issue, the smart shopping device 1 disclosed herein is equipped with a first camera 107 and a second camera 106, primarily used to capture the user's shopping behavior (i.e., the scanned product information) and monitor changes in the goods placed in the shopping basket (i.e., product information within the shopping basket), respectively. The second camera 106 has two operating modes to suit different shopping scenarios. For example, when both cameras work simultaneously, they can monitor different areas within the shopping basket of the shopping cart, ensuring comprehensive coverage and preventing purchased goods from entering the basket from blind spots. The single-camera-106 mode primarily operates when the other camera is obstructed or when the smart shopping device 1's battery is low and it switches to energy-saving mode. When the smart shopping device 1 is in energy-saving mode, the two second cameras 106 will select the second camera 106 with better lighting and recognition to work by judging conditions such as light and recognition, while the other second camera 106 will stop working.

[0102] In one optional embodiment of this disclosure, the smart shopping method for preventing theft and damage to goods includes:

[0103] Step S111: Obtain the second and third product information. That is, when the user takes the product and scans it through the barcode scanner 108, the third product information of the product can be collected. At the same time, the first camera 107 will also collect the second product information of the product.

[0104] Step S121: If, based on the second and / or third product information, it is determined that the product selected by the user is a trained product, the selected product can be placed in the shopping basket of the shopping cart. At this time, the second camera 106 can collect the first product information of the product placed in the shopping basket of the shopping cart. Since the product information can be obtained more comprehensively by scanning the barcode with the barcode scanner 108, in practice, it is preferable to determine whether the product selected by the user is a trained product based on the third product information. If a weight sensor 40 is installed at the bottom of the shopping basket, in addition to collecting the first product information of the product placed in the shopping basket of the shopping cart through the second camera 106, the weight sensor 40 can also collect the fourth product information of the product placed in the shopping basket of the shopping cart, thus acquiring both the first and fourth product information simultaneously.

[0105] Among them, trained products (i.e., non-new products) are products whose relevant information has already been pre-stored in the product database. This product information may include, but is not limited to, information such as the product's packaging format, packaging color, graphics on the packaging, weight, production date, and shelf life. Of course, other product information may also be pre-stored in the product database; merchants can pre-store the specific information as needed, and there are no restrictions here.

[0106] Step S131: Then compare the third product information with the first product information, the second product information, or the fourth product information;

[0107] Step S141: If the similarity obtained from the comparison reaches the first similarity threshold, then confirm the product corresponding to the selected third product information and add it to the shopping list for checkout.

[0108] Step S151: If the similarity obtained by comparison does not reach the first similarity threshold, then push multiple products (such as the three closest products) that are similar to the third product information from the product library for display.

[0109] The first similarity threshold can be set by the merchant and is not limited here.

[0110] Step S161: The user will select one product from the multiple products pushed. At this time, it can be determined whether the selected product matches the region where the selected product is located (i.e., whether the user is located in the region where the selected product is located) based on the product selected by the user among the multiple products pushed.

[0111] Step S171: If the product selected by the user is within the corresponding product area, the two are matched, the product corresponding to the selected third product information is confirmed, and it is added to the shopping list for checkout.

[0112] Step S181: If the product selected by the user is outside the corresponding product area, or if the two do not match, the staff can be prompted and the information in the above-mentioned smart shopping process can be recorded.

[0113] In the above embodiment, steps S161 to S181 are steps to further locate the area of ​​the product selected by the user after confirming the product. Steps S161 to S181 can improve the effect of preventing theft and damage to the product.

[0114] In another optional embodiment of this disclosure, the smart shopping method for preventing theft and damage to goods includes:

[0115] Step S111: Obtain the second and third product information. That is, when the user takes the product and scans it through the barcode scanner 108, the third product information of the product can be collected. At the same time, the first camera 107 will also collect the second product information of the product.

[0116] Step S122: If it is determined that the product selected by the user is an untrained product based on the second product information and / or the third product information, the selected product can be directly placed into the shopping basket of the shopping cart. At this time, the second camera 106 can collect the first product information of the product placed in the shopping basket of the shopping cart. Since the product information can be obtained more comprehensively by scanning the barcode with the barcode scanner 108, in actual circumstances, it is preferable to determine whether the product selected by the user is an untrained product based on the third product information.

[0117] Among them, untrained products (i.e. new products) are products for which no product information has been pre-stored in the product database.

[0118] Step S132: Then compare the first product information with the second product information;

[0119] Step S142: If the similarity obtained from the comparison reaches the second similarity threshold, then confirm the product corresponding to the selected third product information and add it to the shopping list for checkout.

[0120] Step S152: If the similarity obtained by comparison does not reach the second similarity threshold, then push multiple products (such as the three closest products) that are similar to the third product information from the product library for display.

[0121] The second similarity threshold can be set by the merchant and is not limited here. The second similarity threshold can be set to be lower than the first similarity threshold to more accurately identify the selected product when comparing only the first and second product information.

[0122] Step S162: The user will select one product from the multiple products pushed. At this time, it can be determined whether the selected product matches the region where the selected product is located (i.e., whether the user is located in the region where the selected product is located) based on the product selected by the user among the multiple products pushed.

[0123] Step S172: If the product selected by the user is within the corresponding product area, the two are matched, the product corresponding to the selected third product information is confirmed, and it is added to the shopping list for checkout.

[0124] Step S182: If the product selected by the user is outside the corresponding product area, or if the two do not match, the staff can be prompted and the information in the above-mentioned smart shopping process can be recorded.

[0125] In the above embodiment, steps S162 to S182 are steps to further locate the area of ​​the product selected by the user after confirming the product. Steps S162 to S182 can improve the effect of preventing theft and damage to the product.

[0126] In another optional embodiment of this disclosure, the smart shopping method for preventing theft and damage to goods includes:

[0127] Step S113: If the user does not scan the selected product using the barcode scanner 108 and does not collect the third product information, but directly places the selected product into the shopping cart's basket, the second camera 106 can collect the first product information of the product placed in the shopping cart's basket. Simultaneously, the weight sensor 40 collects the fourth product information. The first and / or fourth product information is then compared with product information pre-stored in the product database. Since the image information of the product collected by the second camera 106 is more discriminative and accurate than the weight information collected by the weight sensor 40, it is preferable to compare the first product information with the product information pre-stored in the product database in practice. If both the first and fourth product information are collected simultaneously, they can be used together for comparison with the product information pre-stored in the product database. The addition of the fourth product information helps to narrow the comparison range and improve efficiency.

[0128] Of course, in step S113, it is also possible to compare only the first product information with the product information stored in the product database, or to add a comparison between the fourth product information and the product information stored in the product database, which can narrow the comparison range and find the corresponding product in the product database more accurately.

[0129] Step S123: If the similarity obtained from the comparison reaches the third similarity threshold, then confirm the product corresponding to the selected first product information (if the fourth product information has been collected, the product corresponding to the selected fourth product information can also be confirmed), and add it to the shopping list for settlement.

[0130] Step S133: If the similarity obtained by comparison does not reach the third similarity threshold, then push multiple products (such as the three closest products) that are close to the first product information from the product library for display;

[0131] The third similarity threshold can be set by the merchant and is not limited here.

[0132] Step S143: The user will select one product from the multiple products pushed to the system. At this time, the system can determine whether the selected product matches the region where the selected product is located (i.e., whether the user is located in the region where the selected product is located) based on the product selected by the user among the multiple products pushed to the system.

[0133] Step S153: If the product selected by the user is within the corresponding product area, the two are matched, the product corresponding to the first selected product information is confirmed, and it is added to the shopping list for checkout.

[0134] Step S163: If the product selected by the user is outside the corresponding product area, or if the two do not match, the staff can be prompted and the information in the above-mentioned smart shopping process can be recorded.

[0135] In the above embodiment, steps S143 to S163 are steps to further locate the area of ​​the product selected by the user after confirming the product. Steps S143 to S163 can improve the effect of preventing theft and damage to the product.

[0136] In this embodiment, after step S133, if none of the multiple products pushed are the products selected by the user, or if the user does not select any product from the multiple products pushed, the user is prompted to use the barcode scanner 108 to scan and settle the selected product; if the product is still not scanned and settled, an error message is issued to facilitate staff to check and process the issue.

[0137] In the above steps, when it is necessary to remind staff, the smart shopping device 1 can remind staff to check the shopping cart corresponding to the smart shopping device 1 before leaving the store by sending a message, or by changing the color or flashing the light strip 117 on the smart shopping device 1, or by emitting a reminder sound through the speaker 115, so as to achieve the purpose of preventing theft and damage to goods.

[0138] In an optional embodiment of this disclosure, the smart shopping method further includes, during the shopping process, using a broadband communication module 109 and a narrowband communication module 110 in conjunction to locate the smart shopping device 1, thereby obtaining the shopping cart's trajectory and parking position. Broadband communication offers advantages such as stable signal and high speed, making it suitable for overall communication during the shopping process. Narrowband communication not only assists the shopping cart in indoor positioning calibration, but more importantly, because the narrowband communication module 110 has an additional battery for separate power supply, even after the smart shopping device 1 is powered off, the narrowband communication module 110 can still continuously communicate with the indoor base station, ensuring that the smart shopping device 1 remains within the store, effectively achieving real-time positioning and tracking of the offline smart shopping device 1. The coordination of the broadband communication module 109 and the narrowband communication module 110 for positioning is crucial because even when the broadband communication module 109 and the smart shopping device 1 are not operating, the narrowband communication module 110 can still continuously communicate with the indoor preset base station, ensuring that the smart shopping device 1 remains located within the supermarket store, effectively achieving tracking and positioning of the offline smart shopping device 1, and increasing the security and efficiency of device management. This disclosure also allows the use of a nine-axis sensor 111 in conjunction with a broadband communication module 109 and a narrowband communication module 110 for precise indoor positioning of the smart shopping device 1. This not only improves positioning accuracy but also enables real-time, continuous location tracking of the smart shopping device 1, allowing it to continue operating even when the device is powered off. Furthermore, by precisely positioning the user indoors, the software built into the smart shopping device 1 can target and push relevant advertising and promotional information for products within the corresponding area based on the user's real-time location, and display this information in real-time on the display screen 105, thus increasing the relevance and attractiveness of promotional activities.

[0139] This disclosure, through real-time positioning of the smart shopping device 1, can identify the crowded areas in the store at any given time, allowing staff to promptly understand the distribution of customers and the smart shopping device 1, thus preventing dangerous situations caused by overcrowding and ensuring personnel safety.

[0140] The narrowband communication module 110 disclosed herein can be used in conjunction with a preset communication base station to form an electronic fence. The electronic fence is used to delineate functional areas so as to perform specified actions within the functional areas. This allows for precise control of the functional permissions of the smart shopping device 1 in a specific area, effectively preventing the smart shopping device 1 from being moved out of the specific area (such as being taken out of the supermarket) without authorization.

[0141] Specifically, the narrowband communication module 110 can deploy an electronic fence indoors using methods such as Angle of Arrival (AOA) or triangulation. Without affecting or increasing the normal communication and IP address of the broadband communication module 109, the electronic fence controls the functional permissions of the smart shopping device 1 within a preset specific area indoors. Specified actions within the functional area can include, but are not limited to: the smart shopping device 1 can only enter the product checkout process when the shopping cart reaches the preset checkout area (the checkout area defined by the electronic fence), thus preventing theft of the shopping cart after checkout inside the store; when the smart shopping device 1 reaches a specific promotional area indoors, the coupons in the software can be activated and used, thus realizing offline store interaction. Furthermore, the light strip 117 set on the smart shopping device 1 can provide reminders through color changes or flashing, enhancing the user's shopping experience and interactivity.

[0142] In use, after the smart shopping device 1 is removed from the charging position (e.g., charging base), the smart shopping device 1 is assembled with the base assembly 2. The smart shopping device 1 is securely locked to the base assembly 2 by the locking structure and Hall effect detection element, ensuring that the smart shopping device 1 will not be forcibly removed from the base assembly 2, fall, or be stolen before the locking structure is unlocked. Users can then proceed with their shopping cart purchases as needed. At this time, the pre-installed software within the smart shopping device 1 can push real-time product and promotional information to the display screen 105 based on the user's shopping history and current product area. This personalized and customized information push method makes it easier for users to find their desired products, enhancing their shopping experience. It also improves the accuracy and effectiveness of promotional activities. Furthermore, based on the user's actual purchasing behavior (such as the quantity and frequency of purchases of a particular product), the system analyzes order volume and the time users spend in specific product areas or their vicinity to evaluate the effectiveness of advertising and marketing activities. This provides data support for subsequent advertising and marketing activities, achieving a closed-loop operational model for offline stores that integrates advertising, product purchase quantity, and product dwell time based on device location.

[0143] During use, this disclosure utilizes the positioning function of the broadband communication module 109 and the narrowband communication module 110, along with the function of the first camera 107, the second camera 106, and the barcode scanner 108 to identify goods. This allows for the tracking of the user's specific movement trajectory and parking location within the supermarket, as well as the area and time the shopping cart remains in the store. This enables the collection and analysis of user shopping behavior data, allowing merchants to better understand the shopping behavior and purchasing preferences of different users, and helps optimize store layout and product placement.

[0144] In one optional embodiment of this disclosure, the smart shopping method further includes: completing payment within a preset area after shopping. By restricting the payment area, the security of the payment process is ensured, preventing payment operations in unauthorized areas and reducing the risk of potential fraud (spoofed payments).

[0145] The specific payment process is as follows: after completing their purchase, users can pay by swiping their card via the NFC communication module or by scanning a QR code using a POS machine or mobile phone. The adoption of multiple payment methods increases the convenience and range of choices for users. To ensure the payment process is secure and efficient, a pre-defined area for payment can be established within the supermarket store by setting up base stations. Only within this pre-defined area can the corresponding signal and payment information be received to complete the payment. After payment, the smart shopping device 1 can display the payment status via a light strip 117 or use a speaker 115 and other audio-visual prompts to inform the user that payment has been completed, improving user experience and transparency. Simultaneously, the locking structure between the smart shopping device 1 and the base assembly 2 is unlocked, allowing users to return the smart shopping device 1 to its charging position before leaving. This integrated device management method not only facilitates users' access to the smart shopping device 1 but also facilitates staff monitoring and management of the device's status. After returning the smart shopping device 1, the specific charging location can be obtained via the NFC communication module and transmitted back to the cloud system via the narrowband communication module 110. Afterwards, users can push their shopping cart outside the store to complete the entire shopping process.

[0146] I. The intelligent shopping method disclosed herein can realize intelligent purchase of goods with relatively small modification costs and space costs, saving users queuing time and enabling self-service shopping and checkout.

[0147] Second, the intelligent shopping method disclosed herein can understand users' needs and purchasing preferences by acquiring product purchase information and user location information, so as to accurately push products to users.

[0148] Third, the intelligent shopping method disclosed herein can prevent theft and damage to goods and reduce losses.

[0149] Fourth, the intelligent shopping method provided in this disclosure adopts the above-mentioned shopping settlement device and also has the characteristics and advantages of the above-mentioned shopping settlement device, which will not be repeated here.

[0150] The above description is merely an illustrative embodiment of this disclosure and is not intended to limit the scope of this disclosure.
