[0002] A smart supermarket shopping cart is a shopping cart that integrates multiple advanced technologies. It not only has the function of carrying goods in a regular shopping cart, but also provides a more convenient and efficient shopping experience through the combination of technologies such as the Internet of Things, artificial intelligence, and mobile payment. Because smart supermarket shopping carts are equipped with displays, which contain hardware devices such as sensors, cameras, and barcode scanners, they are easily damaged by collisions. Therefore, anti-collision protection devices are usually installed on the surface of smart supermarket shopping carts.

[0003] However, existing anti-collision protection devices usually only involve installing a plastic shell on the surface of the smart shopping cart for anti-collision protection. When the smart shopping cart is subjected to a large impact, it cannot provide good anti-collision protection. Furthermore, the plastic shell is not very effective at absorbing the vibrations generated after a collision, and therefore cannot effectively protect the smart shopping cart from impacts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, anti-collision protection devices typically only involve installing a plastic shell on the surface of a smart shopping cart for collision protection. However, when the smart shopping cart is subjected to a large impact, this method cannot provide adequate anti-collision protection. Furthermore, the plastic shell is not very effective at absorbing the vibrations generated after a collision, thus failing to provide adequate anti-collision protection for the smart shopping cart. Therefore, this utility model proposes an anti-collision protection device for smart shopping carts.

[0006] The anti-collision protection mechanism includes a protective plate and a fixed plate. The inner side of the protective plate is movably connected to the surface of the shopping basket, and the right side of the fixed plate is fixedly connected to the left side of the shopping basket. A protective groove is provided on the inner side of the inner cavity of the protective plate. A spring and a damping telescopic rod are fixedly connected to the inner cavity of the protective groove. One side of the spring and the damping telescopic rod are fixedly connected to the surface of the shopping basket.

[0007] Preferably, the outer side of the inner cavity of the protective plate is provided with a movable groove, the inner cavity of the movable groove is fixedly connected to a fixed rod, and the surface of the fixed rod is movably connected to a movable roller, the movable roller being made of rubber.

[0008] Preferably, a connecting plate is fixedly connected to the left side of the fixed plate, and a movable groove is provided on the front and back sides of the inner cavity of the connecting plate. A movable plate is movably connected to the inner cavity of the movable groove, and the right side of the movable plate is fixedly connected to the left side of the protective plate.

[0009] Preferably, a limiting rod is fixedly connected to the inner cavity of the movable groove, and the surface of the limiting rod is movably connected to the inner cavity of the movable plate.

[0010] Preferably, a support plate is fixedly connected to both the front and back sides of the bottom of the connecting plate, and the top of the support plate is movably connected to the bottom of the protective plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The present application will be further described in detail below with reference to Figures 1-5.

[0024] This application discloses a smart shopping cart anti-collision protection device. Referring to Figures 1 and 3, a smart shopping cart anti-collision protection device includes a cart body 1, the cart body 1 includes a frame 101, wheels 102 are movably connected to the four corners of the frame 101, a handle 103 is fixedly connected to the left side of the top of the frame 101, and a shopping basket 104 is fixedly connected to the right side of the top of the frame 101. An anti-collision protection mechanism 2 is installed on the surface of the shopping basket 104.

[0025] The anti-collision protection mechanism 2 includes a protective plate 201 and a fixed plate 207. The inner side of the protective plate 201 is movably connected to the surface of the shopping basket 104, and the right side of the fixed plate 207 is fixedly connected to the left side of the shopping basket 104. A protective groove 203 is provided on the inner side of the inner cavity of the protective plate 201. A spring 202 and a damping telescopic rod 204 are fixedly connected to the inner cavity of the protective groove 203. One side of the spring 202 and the damping telescopic rod 204 are fixedly connected to the surface of the shopping basket 104.

[0026] Referring to Figure 4, a movable groove 210 is provided on the outer side of the inner cavity of the protective plate 201. A fixed rod 211 is fixedly connected to the inner cavity of the movable groove 210. A movable roller 209 is movably connected to the surface of the fixed rod 211. The movable roller 209 is made of rubber. The fixed rod 211 provides support for the movable roller 209, allowing the movable roller 209 to rotate inside the movable groove 210. When the movable roller 209 comes into contact with an external object, the vibration transmitted to the protective plate 201 can be reduced.

[0027] Referring to Figures 3 and 5, a connecting plate 208 is fixedly connected to the left side of the fixed plate 207. The front and back sides of the inner cavity of the connecting plate 208 are provided with movable grooves 212. A movable plate 206 is movably connected to the inner cavity of the movable groove 212. The right side of the movable plate 206 is fixedly connected to the left side of the protective plate 201. By setting the movable groove 212, the movable plate 206 can move inside the connecting plate 208, so that the protective plate 201 can move slightly on the surface of the shopping basket 104, thereby reducing the vibration effect on the shopping basket 104.

[0028] Referring to Figure 5, a limiting rod 213 is fixedly connected to the inner cavity of the moving groove 212. The surface of the limiting rod 213 is movably connected to the inner cavity of the movable plate 206. The limiting rod 213 plays a limiting and guiding role in the movement of the movable plate 206, preventing the movable plate 206 from detaching from the inside of the moving groove 212 during the movement.

[0029] Referring to Figure 3, support plates 205 are fixedly connected to the front and back sides of the bottom of the connecting plate 208. The top of the support plate 205 is movably connected to the bottom of the protective plate 201. The support plate 205 provides support for the bottom of the protective plate 201, preventing the protective plate 201 from shifting and ensuring that the protective plate 201 remains at the same level as the shopping basket 104.

[0030] Referring to Figures 1 and 2, a support mechanism 3 is installed on the surface of the handrail 103. The support mechanism 3 includes a fixed sleeve 305. The inner cavity of the fixed sleeve 305 is fixedly connected to the surface of the handrail 103. A fixed seat 303 is fixedly connected to the surface of the fixed sleeve 305. A movable seat 302 is movably connected to the inner cavity of the fixed seat 303. A display screen 301 is fixedly connected to the top of the movable seat 302. By setting the fixed sleeve 305, the position of the fixed seat 303 is fixed. Thus, by setting the fixed seat 303, the position of the display screen 301 can be adjusted to adapt to different needs.

[0031] Referring to Figure 2, a damping sleeve 306 is fixedly connected to the inner cavity of the fixed base 303, and a movable rod 304 is movably connected to the inner cavity of the damping sleeve 306. The surface of the movable rod 304 is fixedly connected to the inner cavity of the movable base 302. The movable rod 304 supports the position of the movable base 302, allowing the display screen 301 to rotate stably inside the fixed base 303. Furthermore, the damping sleeve 306 increases the friction force experienced by the movable rod 304 during rotation, thereby improving the fixing effect of the display screen 301.

[0032] Working principle: During normal use of the shopping basket 104, the frame 101 is moved by holding the handle 103. During this movement, the display screen 301 is rotated, causing the movable seat 302 to rotate. This rotation, in turn, causes the movable rod 304 to rotate within the fixed seat 303, adjusting the display screen 301 to the desired position. During rotation, the movable rod 304 contacts the inner cavity of the damping sleeve 306, increasing friction and improving the stability of the display screen 301, preventing positional shifts. When the shopping basket 104 encounters other objects, the protective plate 201 protects its surface. The object first contacts the surface of the movable roller 209, and upon contact, the movable roller 209 then contacts the object, causing the fixed rod 204 to rotate. The surface of the 11 rotates, thereby reducing the vibration transmitted to the protective plate 201. When the vibration passes through the protective plate 201, the spring 202 and the damping telescopic rod 204 will partially absorb the vibration received by the protective plate 201. When the protective plate 201 is subjected to vibration, it will drive the movable plate 206 to move slightly inside the moving groove 212, thereby weakening the vibration during the movement of the protective plate 201. At the same time, the movable plate 206 will slide on the surface of the limiting rod 213 during the movement, thereby limiting and guiding the movement of the movable plate 206 and preventing the limiting rod 213 from falling out of the moving groove 212 during the movement. When the protective plate 201 moves, its bottom will be supported by the support plate 205, so that the protective plate 201 and the shopping basket 104 are at the same level. After multiple weakening of the vibration, it will be transmitted to the shopping basket 104, ultimately reducing the vibration received by the display screen 301.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
