Description

Technical Field

[0001] This utility model relates to the technical field of shopping guide and inquiry devices, and in particular to a shopping guide and inquiry device for unmanned supermarkets. Background Technology

[0002] With social development, unmanned supermarkets have emerged. For large unmanned supermarkets, the lack of staff means that unfamiliar customers cannot locate the goods, reducing shopping efficiency and convenience. Therefore, unmanned supermarket information retrieval devices have emerged to assist customers in finding the location of goods or places, thus providing guidance. Existing information retrieval devices are typically handheld with a display screen. By inputting the target product or location on the screen and observing the prompts, customers can quickly find the target product or location, thus providing guidance. However, existing devices are primarily handheld, preventing hands-free use, especially for customers using shopping carts. Therefore, it is necessary to design an unmanned supermarket information retrieval device to address these issues. Utility Model Content

[0003] This utility model provides an unmanned supermarket guide and inquiry device. By improving the outer shell of the guide and inquiry device, it enables multiple carrying methods, making it more convenient for customers to use during the shopping process.

[0004] The technical problem solved by this utility model is achieved by the following technical solution:

[0005] This utility model provides an unmanned supermarket shopping guide and query device, including a housing carrier with a hand handle, a touch screen display, and a circuit board. The touch screen display is located on the housing carrier, and the circuit board is located inside the housing carrier. The touch screen display is connected to the circuit board. The hand handle includes a vertical part that is perpendicular to the side wall connected to the housing carrier and a horizontal part integrally formed with the vertical part. The housing carrier is also provided with an elastic clip opposite to the vertical part. The elastic clip and the vertical part form a clamping space for clamping the handle of the shopping cart.

[0006] Preferably, the elastic clip includes a connecting portion connected to the outer shell carrier and a clamping portion integrally formed with the connecting portion, wherein the clamping portion gradually tilts towards the vertical portion from the direction close to the outer shell carrier to the direction away from the outer shell carrier.

[0007] Preferably, the end of the clamping portion away from the connecting portion also has a tail portion, and the tail portion gradually tilts away from the vertical portion from the direction close to the clamping portion to the direction away from the clamping portion.

[0008] Preferably, a first concave arc is provided on the side wall of the vertical portion near the elastic clip, and a second concave arc is provided on the side of the clamping portion near the vertical portion.

[0009] Preferably, a restraint strap is provided on the horizontal part.

[0010] Preferably, the restraint strap is at least one watch strap.

[0011] The beneficial effects of this utility model are: by improving the outer shell carrier of the existing shopping guide query device, the original rod-shaped handle is improved into two parts with a vertical part and a horizontal part.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0028] To enable those skilled in the art to understand the schematic diagram of existing unmanned supermarket guide and inquiry devices, in conjunction with the attached diagram... Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4This paper introduces an existing unmanned supermarket guide and query device, which includes a housing 8 with a handle 9, a circuit board inside the housing 8, and a touch screen 2 on one side wall of the housing 8. In use, the device is carried by holding it on the handle 9. When searching for a target product or location, navigation is achieved by inputting the name of the target product or location on the touch screen 2. Specifically, the navigation function differs from common mobile phone navigation functions in principle. This unmanned supermarket guide and query device is mainly used for precise indoor positioning, so it needs to cooperate with positioning base stations and servers installed inside the unmanned supermarket. In this cooperation process, each unmanned supermarket guide and query device is a positioning tag 1. The circuit board of the positioning tag 1 (guide and query device) has a main control chip 3, a positioning chip 4 (hereinafter referred to as a WIFI chip if WIFI positioning is used), and a communication module 6. When a person inputs the name of a target product or a target location through the touch screen 2, the main control chip 3 obtains the input information and communicates with the server through the communication module 6. The server, based on a pre-set... The stored target product or location is sent to positioning tag 1. After receiving the information from the server, positioning tag 1 displays it on the touch screen 2 in the form of map navigation to assist personnel in navigation. The principle of the server knowing the location of personnel in real time is achieved by relying on positioning base stations. Specifically, there is also a positioning chip 4 on the circuit board. Positioning chip 4 sends signals to positioning base stations installed inside the unmanned supermarket through periodic broadcasts (due to the different distances between positioning chip 4 and positioning base stations, there will be signal attenuation during transmission, so the signal strength received by positioning base stations at different distances will also be different). Positioning base stations transmit the received broadcast signals to the server. The server determines the location of personnel based on the signal strength received by each positioning base station (common calculation methods such as RSSI triangulation or fingerprint positioning). There are many positioning base stations, and their common forms are Bluetooth beacons or WIFI access points (APs). Among them, WIFI access points are considered the best choice as positioning base stations because they are inexpensive (utilizing existing WIFI infrastructure, the deployment cost is low) and the signal stability is better than Bluetooth transmission.Multiple positioning base stations should be installed to cover all target areas while avoiding excessive overlap. Based on pre-stored locations of target goods or locations and broadcast signals received from the positioning base stations, the server can calculate the relative position between personnel and target objects in real time, facilitating navigation. For example, when searching for soy sauce, the positioning tag 1 transmits the information to the server via communication module 6. The server, based on pre-stored information, knows the soy sauce is stored on shelf three in area A and marks its location on a map. Simultaneously, the server calculates the person's current position using broadcast signals received from multiple positioning base stations and marks it on the map, allowing the person to observe the distance to the target product, thus providing a shopping guide function. This type of unmanned supermarket shopping guide device is generally portable for use in large unmanned supermarkets, so it includes a power module 5 (rechargeable for extended use). The outer casing 8 has a charging port 7 on its side wall to charge the power module 5. The above description of the unmanned supermarket shopping guide device is brief and intended to help those skilled in the art understand its specific applications and operating environment.

[0029] As can be seen from the above description, unmanned supermarket guide and inquiry devices often need to be carried around during use to facilitate real-time observation of the user's position relative to the target product or location. However, the conventional handheld method can cause many inconveniences. For example, when selecting products, it is easy to casually toss the guide and inquiry device aside. Similarly, holding the guide and inquiry device in one hand while selecting products can also be inconvenient. In addition, customers who purchase a lot of products usually use shopping carts 14, and it is very inconvenient to push the shopping cart 14 with one hand and hold the guide and inquiry device with the other. Based on the above, in order to better adapt to its specific working environment, the unmanned supermarket guide and inquiry device needs to be improved.

[0030] refer to Figures 5-12This utility model provides an unmanned supermarket guide and inquiry device. Its improvement over existing unmanned guide and inquiry devices lies in the modifications to the outer casing 8 and the handle 9, without specifically involving improvements to the internal circuitry. It also includes the outer casing 8 with the handle 9, a touch screen display 2, and a circuit board. The touch screen display 2 is located on the outer casing 8, and the circuit board is located inside the outer casing 8, connected to the circuit board. The handle 9 includes a vertical portion 901 perpendicular to the sidewall connected to the outer casing 8, and a horizontal portion 902 integrally formed with the vertical portion 901. The outer casing 8 also has an elastic clamp 10 opposite to the vertical portion 901, forming a gripping mechanism between the elastic clamp 10 and the vertical portion 901 for holding the handle 15 of the shopping cart 14. The clamping space indicates that, compared to the straight handle 9 of the prior art, the handle 9 of this utility model has two parts: a horizontal part 902 and a vertical part 901. The horizontal part 902 is convenient for people to hold and carry normally, while the vertical part 901 can cooperate with the elastic clip 10 to clamp onto the armrest 15 of the shopping cart 14, thereby freeing up the hands. Specifically, during the clamping process of the vertical part 901 and the elastic clip 10 on the armrest 15 of the shopping cart 14, the diameter of the armrest 15 of the shopping cart 14 is larger than the distance between the vertical part 901 and the elastic clip 10. Therefore, when the armrest 15 is between the vertical part 901 and the elastic clip 10, the elastic clip 10 deforms to generate clamping force, thereby stabilizing the shopping guide device on the shopping cart 14.

[0031] Further reference Figure 9 and Figure 10 The elastic clip 10 includes a connecting portion 1001 connected to the outer casing carrier 8 (attached). Figure 12 The device is fixed with bolts 12 (but welding can also be used in actual use) and a clamping part 1002 integrally formed with the connecting part 1001. The clamping part 1002 gradually tilts from the direction close to the outer shell carrier 8 to the direction away from the outer shell carrier 8 towards the direction close to the vertical part 901. Thus, the clamping space formed between the clamping part 1002 and the vertical part 901 is shaped as larger at the top and smaller at the bottom. During the clamping process, the side wall of the outer shell carrier 8, the clamping part 1002 and the vertical part 901 each have at least one point in contact with the outer wall of the handle 15 of the shopping cart 14. The multi-point contact increases the stability of the shopping guide query device.

[0032] Furthermore, the clamping part 1002, at the end away from the connecting part 1001, also has a tail 1003. The tail 1003 gradually tilts away from the vertical part 901 from the direction near the clamping part 1002 to the direction away from the clamping part 1002. The tail 1003 can guide the armrest 15 as it enters the clamping space, causing the elastic clamping piece 10 to deform. Specifically, the design of the tail 1003 makes the entrance of the clamping space flared, making it easier for the armrest 15 to enter the interior of the clamping space. At the same time, if... Figure 12 In the middle, the connection between the vertical part 901 and the horizontal part 902 is set as a rounded corner part 903 with a far-angle shape, which cooperates with the tail part 1003 and has a larger flared shape.

[0033] Furthermore, a first concave arc 904 is provided on the side wall of the vertical part 901 near the elastic clip 10, and a second concave arc 1004 is provided on the side of the clamping part 1002 near the vertical part 901. The design of the first concave arc 904 and the second concave arc 1004 can be adapted to the shape of the armrest 15, so that the original point contact becomes surface contact, increasing the friction. Similarly, if the cross-section of the armrest 15 of the shopping cart 14 is rectangular, a corresponding right-angled groove can be opened on the elastic clip 10 or the clamping part 1002 to correspond to it, so as to prevent the shopping guide query device from shaking.

[0034] Furthermore, to further enhance the portability of the shopping guide device, a restraint strap 11 is provided on the horizontal part 902 that can be held. The restraint strap 11 can be fixed to the arm 13 by binding. Specifically, the restraint strap 11 can be designed in the form of a common watch strap for easy fixing and unbinding. At the same time, in order to achieve multi-point fixation and prevent swaying relative to the arm 13 when carrying, multiple watch straps can be provided to fix it to the arm 13.
