Description

Technical Field

[0001] This utility model relates to the field of intelligent shopping cart technology, and in particular to an intelligent following shopping cart. Background Technology

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the number of large self-service supermarkets is increasing day by day. Shopping at supermarkets has become an important part of people's daily life. Shopping carts are trolleys used in large self-service supermarkets to temporarily store goods. Among them, intelligent shopping carts with automatic following function can move automatically and follow shoppers without being lost.

[0003] Authorization notice number CN220208355U discloses a smart shopping cart in the field of shopping cart technology, consisting of a shopping cart body and a power supply rail. The device, in use, allows for portable charging through the interaction of the power supply rail and charging wheels. However, in actual use, due to the high volume of customers in supermarkets, the power supply rail is constantly exposed and easily accumulates various impurities and stains. These impurities and stains include dust, food crumbs, water stains, and various liquids spilled by customers. Over time, these impurities and stains gradually accumulate on the surface of the power supply rail, not only affecting its appearance but, more importantly, significantly interfering with normal current transmission when they come into contact with the charging wheels. The stains may block the current path, leading to poor contact between the charging wheels and the power supply rail, resulting in a significant decrease in the shopping cart's charging efficiency, or even failure to charge. Furthermore, the continuous friction between the charging wheels and the impurity-covered power supply rail accelerates the wear of the charging wheel surface, reducing its lifespan, increasing equipment maintenance costs, and seriously affecting the normal operation and user experience of the smart following shopping cart. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the aforementioned problems with intelligent following shopping carts, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an intelligent following shopping cart, including an intelligent shopping cart body, on which a storage battery is configured, and a connecting rod is also included, hinged to the bottom of the intelligent shopping cart body, with a contact electrically connected to the storage battery at one end of the connecting rod, and a stop plate fixed at the bottom of the other end.

[0007] A ground rail with a groove on top is installed on the ground, and a contact piece that can contact the contact head and conduct electricity is provided in the groove. A protective plate that can cover the contact piece is slidably arranged in the groove. A wiping pad that contacts the surface of the contact piece is provided at the bottom of the protective plate. A movable plate that is slidably connected to the ground rail is fixed on one side of the protective plate and is located on the moving path of the protective plate.

[0008] The ground track has a serpentine walkway, and a round rod with its top end sliding through the serpentine walkway is fixed on the moving plate. When the smart shopping cart moves onto the ground track, the moving plate is pushed forward by the pressure of the abutment plate, and is driven to move laterally back and forth by the lateral swing generated by the round rod along the serpentine walkway path, so that the wiping pad moves in multiple directions on the surface of the contact pad.

[0009] As a preferred embodiment of the intelligent following shopping cart described in this utility model, the protective plate is further provided with a notch, and the projection area of ​​the notch fully exposes the conductive surface of the contact piece.

[0010] As a preferred embodiment of the intelligent following shopping cart described in this utility model, the protective plate is provided with elastic blocks on both sides that are elastically connected to the inner wall of the groove, for limiting and supporting the protective plate.

[0011] In a preferred embodiment of the intelligent following shopping cart described in this utility model, a push plate is connected to the inner wall of the groove on the ground track by at least two springs, and the push plate is always in contact with one side of the protective plate.

[0012] In a preferred embodiment of the intelligent following shopping cart described in this utility model, a pulley is rotatably provided at the end of the connecting rod away from the contact, and the connecting rod and the intelligent shopping cart body are elastically connected by at least two springs.

[0013] As a preferred embodiment of the intelligent following shopping cart described in this utility model, the ground rail is provided with a through groove located on the movement path of the pulley, and one end of the moving plate is located in the through groove. The through groove is composed of an inclined surface and a straight surface. When the pulley slides on the inclined surface, the contact rotates downward around the hinge axis. When the pulley slides on the straight surface, the contact contacts the contact piece.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using a cleaning pad located at the bottom of the protective plate, the smart shopping cart body can perform multi-directional wiping of the contact surface when it moves to the ground track. This effectively removes dust, oil, and other impurities that accumulate on the contact surface due to long-term exposure, ensuring that the contact surface remains smooth and clean. This significantly improves the contact reliability between the contacts and the contact pieces, avoids poor contact problems caused by contamination, thus ensuring the stability and continuity of the charging process, extending the contact lifespan, and reducing maintenance costs.

[0016] 2. By incorporating a connecting rod that rotates with the pulley, the contacts can be moved. During operation, the contacts automatically retract inside the smart shopping cart body, effectively preventing dust contamination and mechanical damage. When moved to the charging position on the ground rail, the contacts extend and engage with the contact plates, enabling automatic battery power supply. This not only solves the problem of poor contact caused by contamination in traditional fixed contacts but also makes the charging process intelligent and convenient, significantly improving the reliability and ease of operation of the equipment.

[0029] Reference Figures 1-6 This invention provides an intelligent following shopping cart, comprising an intelligent shopping cart body 1, a battery 13 mounted on the base of the intelligent shopping cart body 1, and an external protective plate; a touch screen 11 and a sensor 12 are located near the handle; the touch screen 11 has a built-in product navigation system connected to the supermarket database, which can display the specific location and optimal path of the product in the store based on the name entered by the user; the sensor 12 is carried by the user, enabling the shopping cart to automatically follow the user; the intelligent shopping cart body 1 is also equipped with a fast checkout system, after the user completes the selection, the user can select the checkout function through the touch screen 11, and the intelligent shopping cart body 1 will navigate to the designated exit through the navigation system, speeding up the checkout process.

[0030] In addition, sensor 12 is a wearable device with a built-in Bluetooth or UWB positioning module. It works with positioning base stations in the supermarket to achieve indoor positioning with centimeter-level accuracy. Touch screen 11 also integrates a product recommendation function, which recommends relevant products based on the user's shopping history and currently selected products through big data analysis. The bottom of the smart shopping cart body 1 is equipped with an automatic following system, including obstacle avoidance sensors and a mobile cart. It can automatically adjust its driving direction and speed according to the signals sent by sensor 12 to maintain a safe distance from the user.

[0031] like Figure 3 As shown, it also includes a connecting rod 2, which is hinged to the bottom of the smart shopping cart body 1. One end of the rod is provided with a contact 21 that is electrically connected to the battery 13, and a bottom plate 24 is fixed to the bottom.

[0032] like Figure 4 and Figure 5 As shown, a ground rail 3 with a groove at the top is installed on the ground, and a contact piece 31 that can contact the contact 21 for conduction is provided in the groove. A protective plate 4 that can cover the contact piece 31 is slidably arranged in the groove. A wiping pad 42 that contacts the surface of the contact piece 31 is provided at the bottom of the protective plate 4. The wiping pad 42 is removable for easy replacement. A push plate 61 is connected to the inner wall of the groove on the ground rail 3 by at least two springs 6. The push plate 61 is always in contact with one side of the protective plate 4. Under the elastic force of the springs 6, the push plate 61 can apply a reverse force to the protective plate 4 after the smart shopping cart body 1 leaves the ground rail 3, so that it resets and covers the contact piece 31 to form a protective effect. Both sides of the protective plate 4 are provided with elastic blocks 43 that are elastically connected to the inner wall of the groove for limiting and supporting the protective plate 4. The elastic blocks 43 provide lateral support force during the movement of the protective plate 4, making its movement smoother. A notch 41 is also provided on the protective plate 4. The projection area of ​​the notch 41 completely exposes the conductive surface of the contact piece 31.

[0033] A serpentine walkway 32 is provided on the ground track 3, and a round rod 51 with its top end sliding through the serpentine walkway 32 is fixed on the movable plate 5. When the round rod 51 moves on the serpentine walkway 32, it can cause the movable plate 5 to swing laterally during its forward movement.

[0034] When the smart shopping cart body 1 moves onto the ground track 3, the moving plate 5 is pushed forward by the pressure plate 24 and driven to move laterally back and forth by the lateral swing generated by the round rod 51 along the serpentine path 32. This causes the wiping pad 42 to move in multiple directions on the contact piece 31. The multi-directional movement of the wiping pad 42 can wipe the surface of the contact piece 31. Compared with conventional wiping methods, multi-directional wiping can impact some stubborn stains from multiple angles, generating a more complex and powerful friction force at the moment the wiping pad 42 contacts the stains. This makes it difficult for stubborn stains to adhere under the action of forces in different directions, thus achieving a more thorough cleaning and ensuring that the surface of the contact piece 31 remains smooth and clean. This significantly improves the contact reliability between the contact 21 and the contact piece 31, avoids poor contact problems caused by contamination, ensures the stability and continuity of the charging process, extends the service life of the contacts, and reduces maintenance costs.

[0035] A movable plate 5 is fixed on one side of the protective plate 4 and slidably connected to the ground rail 3, and is located on the moving path of the abutment plate 24. That is, when the smart shopping cart body 1 moves onto the ground rail 3, the abutment plate 24 can squeeze the movable plate 5 and drive it to move synchronously. A pulley 22 is rotatably provided on the end of the connecting rod 2 away from the contact 21. The connecting rod 2 and the smart shopping cart body 1 are elastically connected by at least two springs 23, and the springs 23 are in a compressed state. A through groove 33 is opened on the ground rail 3, located on the moving path of the pulley 22, and one end of the movable plate 5 is located in the through groove 33. The through groove 33 is composed of an inclined surface and a straight surface. When the pulley 22 slides on the inclined surface, the contact 21 rotates downward around the hinge axis. When the pulley 22 slides on the straight surface, the contact 21 contacts the contact piece 31.

[0036] Through the coordinated design of the connecting rod 2 and the ground rail 3, the automatic extension and retraction function of the contact 21 is realized. When the shopping cart moves to the charging area, the pulley 22 slides along the inclined and straight surfaces of the through groove 33, driving the contact 21 to precisely press down and contact the contact piece 31, completing automatic alignment and charging; when leaving, the contact 21 automatically retracts, avoiding wear and tear during daily use. In daily use, the contact 21 can be completely stored inside the smart shopping cart body 1, effectively avoiding dust contamination and mechanical damage.

[0037] In addition, a stop plate 34 is also provided on the ground rail 3 to limit the movement of the smart shopping cart body 1, so that the contact 21 can be aligned with the contact piece 31.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
