Description

Technical Field

[0001] This utility model relates to the field of shopping equipment, and more particularly to a shopping cart. Background Technology

[0002] In the current retail industry, shopping carts are widely used as an important tool for consumers when shopping, but there are still many problems with the shopping carts commonly used in the market.

[0003] For example, on the one hand, the shopping carts on the market have diverse structures. Different brands and models of shopping carts vary greatly in size, shape and structural type. This makes it difficult to meet the demand for modification in the smart shopping cart market. If merchants want to upgrade ordinary shopping carts to shopping carts with a certain degree of intelligence (by installing smart shopping terminals on the shopping carts), they often need to invest a lot of money to replace the entire cart, which greatly increases operating costs.

[0004] On the other hand, most existing smart shopping carts fix the smart shopping terminal to the frame, which has obvious drawbacks. When the shopping cart is pushed outside the store, the smart shopping terminal fixed to the frame is easily lost; at the same time, the outdoor environment (wind, sun, etc.) will accelerate the aging and damage of the smart shopping terminal, shorten its lifespan, and increase the maintenance cost of the equipment.

[0005] On the other hand, existing shopping carts are often pushed outside the mall by consumers, and merchants cannot know the exact location of the shopping carts in time to retrieve them, which can easily lead to the loss of shopping carts or the smart shopping terminals on them, causing serious losses to merchants.

[0006] There are currently no effective solutions to the problems of inconvenient and costly retrofitting of smart shopping carts, as well as the easy damage and loss of smart shopping terminals on smart shopping carts.

[0007] Therefore, this utility model proposes a shopping cart to overcome at least one of the above-mentioned technical problems. Utility Model Content

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0060] like Figures 1 to 16 As shown, this utility model provides a shopping cart, which includes a frame 7, a basket 9, a positioning module 2, and multiple wheels 8. The top of the frame 7 has a handle 6, the basket 9 is detachably mounted on the top of the frame 7, and the multiple wheels 8 are detachably mounted on the bottom of the frame 7. The positioning module 2 is mounted on one of the frame 7, the basket 9, and the wheels 8. The positioning module 2 is used to monitor the position of the shopping cart in real time, effectively preventing the shopping cart and the smart shopping terminal 5 on it from being lost, thus avoiding losses for merchants.

[0061] In this invention, the smart shopping terminal 5 may be, but is not limited to, a tablet computer with pre-installed software, allowing consumers to directly query, identify, and purchase the goods they wish to buy by operating the tablet.

[0062] In an optional embodiment of this utility model, the device mounting slot 1 can be directly provided on the handle 6, and the positioning module 2 can be located in the device mounting slot 1, that is, the positioning module 2 is part of the handle 6.

[0063] Of course, in another optional embodiment of this utility model, such as Figures 1 to 3As shown, an installation module 4 for mounting the smart shopping terminal 5 is provided on the handle 6. The installation module 4 has a device mounting slot 1, in which the positioning module 2 can be placed. The positioning module 2 is then mounted on the handle 6 via the installation module 4. This method, through the installation module 4, facilitates the assembly and disassembly of the smart shopping terminal 5 and the positioning module 2, providing better compatibility. When shopping, the smart shopping terminal 5 can be plugged into the preset slot on the installation module 4, allowing consumers to search, identify, and purchase goods while using the shopping cart. In this embodiment, the positioning module 2 is placed in the device mounting slot 1. While the consumer is using the shopping cart, the positioning module 2 can monitor the shopping cart's location in real time. The positioning module 2 supports both indoor and outdoor positioning, ensuring that both the smart shopping terminal 5 and the shopping cart are used within a defined area, improving the safety and management efficiency of the shopping cart.

[0064] In this invention, the positioning module 2 is placed inside the device mounting slot 1. While ensuring real-time monitoring of the shopping cart's position, the positioning module 2 is no longer exposed on the outside of the shopping cart, thus avoiding the aging, damage, and loss of the positioning module caused by the external environment, and effectively extending the service life of the positioning module 2.

[0065] In this invention, the positioning module 2 enables indoor and outdoor positioning of the shopping cart. Indoor positioning and communication of the shopping cart facilitates operational optimization and other services. Outdoor positioning and communication of the shopping cart enable the tracking and retrieval of shopping carts that have been pushed out of the supermarket's designated area.

[0066] In this invention, the positioning module 2 and the power module 3 can be adapted to different installation positions according to the actual structure of the shopping cart. For example, the device mounting slot 1 can be set on the frame 7 of the shopping cart (such as inside the general base of the shopping cart), which is an external installation; of course, as described above, the device mounting slot 1 can also be set on the handle 6 of the shopping cart (that is, the positioning module 2 and the power module 3 are set inside the handle 6), which is an internal installation, to meet different installation needs of the shopping cart and has better adaptability.

[0067] In this invention, the positioning module 2 can be, but is not limited to, an electronic tag, a Bluetooth positioning module, or an ultra-wideband positioning module. Of course, other positioning elements can also be used, as long as they can collect data on the shopping cart's position within a preset range to achieve the purpose of monitoring the shopping cart's location.

[0068] In one optional embodiment of this utility model, such as Figure 3As shown, a power module 3 is also provided in the equipment mounting slot 1. The power supply end of the power module 3 is electrically connected to the power supply end of the positioning module 2. The power module 3 is used to supply power to the positioning module 2 to ensure the long-term and stable working state of the positioning module 2.

[0069] Furthermore, the power module 3 includes a battery, which is detachably mounted in the device mounting slot 1. The battery can be a rechargeable battery, allowing for simultaneous removal and charging of batteries from multiple shopping carts to improve charging efficiency.

[0070] In this utility model, the power module 3 can not only supply power to the positioning module 2, but also supply power to other electrical devices on the shopping cart (such as the wheel locks and the cart locks) as needed. Furthermore, it can adapt to a temperature range of -20℃ to 70℃ in outdoor environments, thus meeting the usage needs of different regions and seasons.

[0071] In an optional embodiment of this invention, the shopping cart has a charging interface (not shown). Specifically, the charging interface can be located on the handle 6 and connected to the device mounting slot 1. The charging interface can charge the power module 3 or the smart shopping terminal 5 located within the device mounting slot 1. In terms of charging design, multiple shopping carts can be cascaded and connected to a charger via fixed contacts to charge the battery and the smart shopping terminal 5.

[0072] In an optional embodiment of this utility model, depending on actual needs, the device mounting slot 1 can be used to insert one or more smart shopping terminals 5, and the smart shopping terminal 5 can be locked with the device mounting slot after being inserted into a preset position in the device mounting slot 1.

[0073] Specifically, a matching snap-fit ​​structure (such as a slot and a block) can be installed inside the device mounting slot 1 and on the outer wall of the smart shopping terminal 5. When the smart shopping terminal 5 is inserted into the preset position within the device mounting slot 1, the snap-fit ​​structure securely locks it in place, ensuring the stability of the smart shopping terminal 5 and preventing its loss. When the shopping cart is pushed outside the preset restricted area, the smart shopping terminal 5 will remind the consumer to return both the cart and the terminal. If the consumer fails to return them promptly, the smart shopping terminal 5 will send an alarm message to the backend to alert the merchant, effectively preventing the loss of the smart shopping terminal 5.

[0074] In an optional embodiment of this utility model, the positioning device includes an antenna, and the antenna and the positioning module 2 are connected by a snap-fit. The snap-fit ​​can be, but is not limited to, various existing anti-disengagement structures, designed to facilitate the assembly and disassembly of the antenna and the positioning module 2, and to ensure a stable structural connection between the two, preventing disconnection due to vibration. The specific structure of the anti-disengagement snap-fit ​​is not limited here.

[0075] Furthermore, the antenna in this embodiment can be a dual-antenna structure, using the carrier phase difference between the two antennas to locate the shopping cart's position. In this embodiment, the carrier phase differential technology used in the dual-antenna structure is a mature existing technology and will not be specifically described here. The positioning module 2 can simultaneously have outdoor and indoor positioning functions. The antenna can be placed inside the shopping cart frame 7, or on both sides of the shopping cart handle 6, effectively avoiding metal and plastic parts on the shopping cart to prevent signal shielding and interference, ensuring stable transmission of the positioning signal. In addition, the positioning module 2 in this application adopts a waterproof structure with an IP65 waterproof rating, enabling it to adapt to humid shopping environments, providing better applicability and extending its service life.

[0076] In one optional embodiment of this utility model, such as Figure 1 , Figure 2 , Figures 4 to 10 As shown, the shopping cart also includes a control mechanism that can lock and unlock multiple wheels 8 respectively; a communication module is provided on the frame 7 or inside the wheels 8. The communication module is used to receive the out-of-area signal emitted by the preset electronic fence. The communication module is electrically connected to the control mechanism. When the communication module receives the out-of-area signal emitted by the electronic fence, the control mechanism locks the wheels 8 to prevent the shopping cart from continuing to move.

[0077] In this invention, the communication module may be, but is not limited to, a Bluetooth module, a WIFI module, and / or a UWB positioning tag module. Additionally, the wheels 8 used in this invention may be conventional wheels or smart wheels, but all must be omnidirectional wheels capable of adjusting their direction in real time according to the shopping cart's direction of travel, ensuring smooth turning and forward movement of the shopping cart.

[0078] In an optional embodiment of this utility model, the control mechanism includes a brake direction control component, which is connected to the wheel 8. When the communication module receives an out-of-zone signal, the brake direction control component drives the wheel 8 to deflect to a deflection angle with the current direction of travel, thereby locking the wheel 8. At this time, the shopping cart can no longer be pushed forward, thereby preventing the shopping cart from being pushed outside the preset restricted area.

[0079] Furthermore, to achieve the aforementioned goal of preventing the shopping cart from moving forward by controlling the deflection direction of the wheels 8, at least two wheels 8 need to deflect, and the deflection angle or direction of at least two wheels 8 relative to the current direction of travel must be different. That is, the axles of the two deflecting wheels 8 are in a non-parallel position. When the shopping cart moves forward, the two deflecting wheels 8 will interfere with each other, hindering the normal forward movement of the shopping cart while preventing the shopping cart from turning, thereby achieving the effect of locking the movement of the shopping cart.

[0080] In one optional embodiment of this utility model, such as Figure 1 , Figure 2 and Figures 4 to 10 As shown, there are four wheels 8, which are located at the bottom of the frame 7, and are positioned at the four vertices of the quadrilateral, with two wheels 8 in the front and two wheels 8 in the rear. Figure 8 As shown, under normal forward movement, the four wheels 8 do not deflect, and the shopping cart can move forward normally when pushed. When the communication module receives an out-of-zone signal, the braking direction control component can control at least the two front wheels 8 to deflect at different angles or directions relative to the current direction of travel, or control at least the two rear wheels 8 to deflect at different angles or directions relative to the current direction of travel, both of which can achieve the purpose of braking.

[0081] like Figure 9 As shown, the two front wheels 8 can be deflected into an "inward" arrangement. At this time, due to the mutual interference between the two front wheels, they cannot rotate synchronously, thus achieving the purpose of braking. In another specific embodiment of this utility model, as... Figure 10 As shown, the two front wheels 8 can be deflected into an "outward" arrangement. In this case, because the two front wheels 8 interfere with each other, they cannot rotate synchronously, thus achieving the same braking effect. Similarly, the two rear wheels 8 can also be deflected, causing the two rear wheels to be arranged in an "inward" or "outward" arrangement, achieving the same braking effect.

[0082] In another optional embodiment of this utility model, in addition to controlling the two front wheels 8 to deflect and interfere with each other, among the four wheels 8, at least the front wheel 8 and the rear wheel 8 can be controlled to have different deflection angles or directions relative to the current direction of travel. This also achieves the purpose of mutual interference between the two deflecting wheels 8 when the shopping cart is moving forward, thereby hindering the normal forward movement of the shopping cart while preventing it from turning, thus achieving the purpose of braking.

[0083] Of course, in this utility model, the specific deflection direction and deflection angle of the brake direction control component controlling the wheel 8 are not limited, as long as the two wheels 8 that deflect each other can interfere with each other to achieve the purpose of braking.

[0084] In an optional embodiment of this utility model, the brake direction control component includes a geared motor or a servo motor, which is mounted on the frame 7. The output shaft of the geared motor or servo motor is connected to the wheel 8. During use, depending on the location of the shopping cart, when the shopping cart is pushed outside the restricted area, the communication module sends a signal to control the geared motor or servo motor, thereby causing the corresponding wheel 8 to deflect through the geared motor or servo motor to achieve the purpose of braking.

[0085] The shopping cart of this invention can monitor the area where the shopping cart is located in real time. When the communication module detects that the shopping cart has exceeded the preset limit area (that is, the communication module receives the over-range signal issued by the preset electronic fence), the brake direction control component can control at least two wheels 8 of the shopping cart to deflect. The two wheels 8 have different deflection angles or deflection directions relative to the current direction of travel, thereby realizing the forward locking function of the shopping cart, preventing the shopping cart from being pushed outside the preset limit area, effectively preventing the shopping cart from being lost, and improving the safety of using the shopping cart.

[0086] In an optional embodiment of this invention, a chain lock (not shown) is provided on the frame 7 or handle 6 of the shopping cart. The handle 6 has a positioning hole that can engage with the chain lock for locking. The chain lock on one of the two shopping carts can be inserted into the positioning hole on the other shopping cart to connect the two carts. This allows multiple shopping carts to be linked together and placed in a centralized manner when not in use. When a consumer needs to use the shopping cart, the chain lock can be unlocked via the smart shopping terminal 5, or opened using an existing coin unlocking method, allowing access to the shopping cart.

[0087] In one optional embodiment of this utility model, such as Figure 1 , Figure 2 , Figures 4 to 7 , Figures 11 to 14 As shown, the left and right sides of the frame 7 have connecting parts 701 extending backward and upward respectively. The handlebars 6 are rod-shaped and arranged in a horizontal direction. The two ends of the handlebars 6 are connected to the top of the two connecting parts 701 by buckles or screws 10, which can ensure the stable connection between the handlebars 6 and the frame 7 and facilitate the replacement of the handlebars 6.

[0088] Specifically, such as Figure 6 , Figures 14 to 16As shown, a connector 703 can be provided at the end of the connecting part 701. The connector 703 is fastened to the connecting part 701 by screws 10. The handle 6 includes an inner rod 601 and an outer tube 602. The outer tube 602 is sleeved on the inner rod 601. The connector 703 has a positioning groove 7031 at a position opposite to the inner rod 601. In the assembled state, the end of the inner rod 601 extends into the positioning groove 7031 of the connector 703, while the outer tube 602 is sleeved on the outside of the positioning groove 7031. A coupling member 603 is provided between the outer tube 602 and the connector 703. The coupling member 603 locks the outer tube 602 and the connector 703, thereby providing circumferential positioning for the handle 6 and preventing the handle 6 from rotating when the consumer pushes the shopping cart.

[0089] Furthermore, such as Figure 15 As shown, the coupling element 603 can be, but is not limited to, a locating pin. A first through hole 6021 is provided on the outer tube 602, and a second through hole 7033 is provided on the locating groove 7031. When the outer tube 602 is fitted onto the outside of the locating groove 7031, the first through hole 6021 and the second through hole 7033 communicate with each other. The locating pin is then inserted into the first through hole 6021 and the second through hole 7033, thereby locking the outer tube 602 and the coupling element 703.

[0090] Furthermore, such as Figure 15 As shown, the end of the inner rod 601 has a first engaging portion 6011, and the inner wall of the positioning groove 7031 has a second engaging portion 7032. When the end of the inner rod 601 extends into the positioning groove 7031, the inner rod 601 and the positioning groove 7031 are engaged by the first engaging portion 6011 and the second engaging portion 7032, thereby achieving circumferential positioning of the inner rod 601. The first engaging portion 6011 and the second engaging portion 7032 can be, but are not limited to, mating grooves and protrusions.

[0091] In an optional embodiment of this utility model, a fixing structure is provided between the bottom of the basket 9 and the top of the frame 7. A weighing sensor (not shown) is installed on the fixing structure to weigh the goods inside the basket 9. Even without installing a weighing sensor, the bottom of the basket 9 and the top of the frame 7 can be connected by a fixing structure. A position for installing a weighing sensor is reserved on the fixing structure. If a weighing sensor needs to be added later, it can be directly installed on the fixing structure, which facilitates the subsequent modification of the shopping cart to have a weighing function and reduces modification costs. In this utility model, the specific structure of the fixing structure is not limited. The fixing structure can stably connect the basket 9 to the top of the frame 7 and has a reserved installation position for installing a weighing sensor.

[0092] In an optional embodiment of this utility model, an image acquisition device (not shown) is provided at the bottom of the frame to collect shopping information. For example, the image acquisition device can capture images of goods placed in the basket 9, and combined with the smart shopping terminal 5, it can be confirmed whether the goods placed in the basket 9 correspond to the goods scanned by the smart shopping terminal 5, thereby effectively preventing theft or missed scanning. The image acquisition device may be, but is not limited to, a camera.

[0093] In one optional embodiment of this utility model, such as Figure 11 As shown, the frame 7 can be formed by bending and welding hollow square or round tubes. Therefore, the frame 7 has a cavity (i.e., the hollow part of the square or round tube). This cavity can be used to lay electrical wires, which are run through the cavity, thus achieving concealed wiring. Of course, as... Figure 12 and Figure 13 As shown, the frame 7 can also be formed by bending and welding solid rod-shaped material or solid plate-shaped material. In this utility model, the material of the formed frame 7 is not specifically limited.

[0094] Furthermore, such as Figure 12 As shown, when the frame 7 is formed from solid material, wiring grooves 702 can be pre-set on the outer wall of the frame 7. Electrical wires are laid in the wiring grooves 702 and fixed with wire clips, which can also achieve hidden wiring. Various electrical wires (such as VCC, GND, single bus, differential signal, SPI / UART / CAN bus, etc.) can be configured as needed to meet the communication and power supply requirements of different devices.

[0095] In the above embodiment, the frame 7 meets the requirement of bearing a maximum weight of 150kg and has the ability to resist tipping over, thus meeting the shopping carrying needs of consumers.

[0096] The shopping cart of this utility model is applicable to a variety of scenarios (such as various supermarkets, shopping malls, warehouse membership stores, and online and offline integrated retail scenarios).

[0097] This utility model's shopping cart can be of two types: non-powered and powered. The non-powered type requires the consumer to manually push the cart to control its movement, and is suitable for small supermarkets and other places with relatively simple shopping environments. The powered type, on the other hand, can use electric wheels, that is, the movement of the wheels 8 is electrically controlled, and is suitable for large supermarkets or places with higher requirements for the intelligence of the shopping cart, thereby improving the consumer's shopping experience.

[0098] When the application scenario is a small supermarket using a non-powered smart shopping cart, the frame 7 can be adapted to small plastic baskets and conventional casters. A cylindrical handle 6 can be used, and a pluggable smart shopping terminal 5 can be fixed in the device mounting slot 1 on the handle 6, using a built-in positioning module 2 and power module 3.
