Description

Technical Field

[0001] This utility model relates to the field of self-service locker technology, and more specifically, to a weighable intelligent self-service locker. Background Technology

[0002] Self-service lockers are intelligent storage devices specifically designed for goods. They are typically placed in densely populated areas. The lockers contain the goods and have prices set. In this modified form, the lockers can be used as vending machines. By setting up self-service lockers, the problem of consumers having to go to the store to buy goods in the traditional way is effectively solved, providing consumers with a flexible and convenient purchasing option.

[0003] Currently, in order to sell goods, a weight sensor is placed on the bottom of the product to weigh it, and the price is calculated based on the change in weight.

[0004] However, existing weight sensors are directly installed on the bottom of the weighing pan. When they are directly connected, external vibrations will be directly transmitted to the sensor, causing fluctuations in the weighing data and affecting the weighing results of the weight sensor. This paper proposes a weighable intelligent self-service locker to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a weighable intelligent self-service locker.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A weighable smart self-service locker includes a cabinet body, the bottom of which is equipped with several casters. Two sets of uprights are symmetrically arranged vertically in the middle of the interior of the cabinet body, and several weighing structures are arranged horizontally on opposite sides of the two sets of uprights.

[0007] The weighing structure includes an installation structure, a weight sensor is installed inside the installation structure, a connecting structure is installed on top of the weight sensor, and a top weighing pan is installed on top of the connecting structure.

[0008] By adopting the above technical solution, the top of the weighing structure is usually equipped with a placement slot for placing goods. The control system of the smart self-service locker is integrated into the back of the locker. Since the door frame and the locker are connected by a hinge, the door frame can rotate along the hinge. The smart control system can control the opening and closing of the electric lock. When the electric lock is opened, the door frame opens along the hinge, making it easier for consumers to take the goods. The product information and the goods can be displayed on the screen for easy viewing by consumers. The card reader provides a convenient payment channel for consumers. Consumers can pay directly with a consumer card. In addition, a QR code can be pasted for consumers to scan and pay. At the same time, the smart control system can also obtain the numerical changes of the weighing structure and output the corresponding weight calculation results and prices to the display screen according to the data processing rules. In addition, the door frame is used to install the locker door, which is used to isolate the internal and external environments and reduce the contamination of the internal goods by the external environment. The top weighing pan is indirectly connected to the weight sensor through a connecting structure, rather than in direct contact. This reduces the risk of direct wear or corrosion to the weight sensor from the items being weighed. Furthermore, if a top weighing pan of different material or size is needed to adapt to different weighing scenarios, only the connection between the top weighing pan and the connecting structure needs to be disassembled, without modifying the weight sensor, greatly improving the flexibility of scenario adaptation.

[0009] The present invention is further configured such that: one end of the base and the two sets of side supports are connected to the column by bolts, and the other end of the base and the two sets of side supports are connected to the inner wall of the box by bolts.

[0010] By adopting the above technical solution, the two sets of side brackets cooperate with the base to form a triangular support structure, and the two ends are respectively connected to the column and the inner side wall of the box by bolts. This two-way fixed design can distribute the load of the weighing system to the column and the box, avoid the weight being concentrated on a single point of the base, reduce the risk of base deformation, and reduce the possibility of deformation being transmitted to the weight sensor and affecting the data. The symmetrical design of the side brackets further balances the force of the overall structure, reduces the tilting of the installation structure caused by excessive force on one side, indirectly improves the horizontal state of the top weighing plate, and reduces the force transmission deviation caused by the tilting of the top weighing plate.

[0011] The present invention is further configured such that: the connecting structure includes two sets of connecting rods, and the two sets of connecting rods are respectively provided with insertion holes on opposite sides, and the shape of the connecting rods is U-shaped.

[0012] The present invention is further configured such that: a connecting frame is provided at the middle position of the two sets of connecting rods, and two sets of insertion holes are respectively passed through the two ends of the connecting frame; the weight sensor is provided at the bottom of the connecting frame; and the connecting frame and the weight sensor are connected by bolts.

[0013] The present invention is further configured such that: a display screen is provided on one side of the top of the box, and a card reader is provided on the outer side wall of the box.

[0014] The present invention is further configured such that: a set of door frames is provided on one side of each set of weighing structures, the door frames are used to install cabinet doors, and each set of door frames is provided with a set of electronic locks.

[0015] In summary, this application includes at least one of the following beneficial technical effects: The top weighing pan is indirectly connected to the weight sensor through a connecting structure, rather than in direct contact. When the top weighing pan receives an object, it can initially disperse the local impact force through its own rigidity, and then further buffer it through the connecting structure before transmitting it to the weight sensor. This reduces the damage to the sensor from instantaneous impact and improves the stability of the measurement data. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: Example 1, see Figure 1 A weighable smart self-service locker includes a cabinet 1, with several casters 2 at the bottom of the cabinet 1, and two sets of uprights 4 arranged symmetrically along the vertical direction in the middle of the interior of the cabinet 1. Several weighing structures 3 are arranged horizontally on opposite sides of the two sets of uprights 4.

[0025] See Figure 1 A display screen 5 is installed on one side of the top of the box 1, and a card reader 6 is installed on the outer side wall of the box 1.

[0026] See Figure 1 Each set of weighing structures 3 has a set of door frames 7 on one side. The door frames 7 are used to install cabinet doors, and each set of door frames 7 is equipped with a set of electric locks.

[0027] Among them, two sets of columns 4 and several weighing structures 3 can be arranged side by side to form multiple placement spaces. The top of the weighing structure 3 can be used to place packaged products, and consumers can choose according to their needs.

[0028] The control system of the smart self-service locker is integrated into the back of the locker body 1. Since the door frame 7 is connected to the locker body 1 by a door hinge, the door frame 7 can rotate along the door hinge. The smart control system can control the opening and closing of the electric lock. When the locker door needs to be closed, it can be closed manually. Under the pressure of a hand, the locker door and the electric lock will cooperate to close the locker door. When the electric lock is opened, it will automatically open under the control of the control system, that is, the door frame 7 will open along the door hinge, making it easier for consumers to take the goods. The product information and the products can be displayed on the display screen 5 for consumers to view. The card reader 6 provides a convenient payment channel for consumers. Consumers can pay directly with a consumer card. In addition, a QR code can be pasted for consumers to scan and pay.

[0029] Meanwhile, the intelligent control system can also acquire the numerical changes of the weighing structure 3, and output the corresponding weight calculation results and price to the display screen 5 according to the data processing rules.

[0030] In addition, the door frame 7 is used to install the cabinet door, which is used to isolate the internal and external environments and reduce the contamination of the internal goods by the external environment.

[0031] See Figure 2 and Figure 3 The weighing structure 3 includes an installation structure 31, a weight sensor 33 is installed inside the installation structure 31, a connecting structure 34 is installed on the top of the weight sensor 33, and a top weighing plate 32 is installed on the top of the connecting structure 34.

[0032] The top weighing pan 32 is indirectly connected to the weight sensor 33 through the connecting structure 34, rather than in direct contact. This reduces the direct wear and corrosion of the weight sensor 33 by the items to be weighed. Furthermore, if a top weighing pan 32 of different material or size is required to adapt to different weighing scenarios, the connection between the top weighing pan 32 and the connecting structure 34 can be disassembled without modifying the weight sensor 33, greatly improving the flexibility of scenario adaptation.

[0033] When the top weighing pan 32 receives an item, it can initially disperse the local impact force through its own rigidity, such as the instantaneous load when the item is placed quickly. Then, it is further buffered by the connecting structure 34 before being transmitted to the weight sensor 33, reducing the damage to the sensor caused by the instantaneous impact and improving the stability of the measurement data.

[0034] See Figure 2 and Figure 3 The mounting structure 31 includes a base 312, with a set of side brackets 311 on each side of the base 312, and a weight sensor 33 in the middle of the base 312. The weight sensor 33 is connected to the base 312 by bolts.

[0035] See Figure 4 and Figure 5 One end of the base 312 and the two sets of side supports 311 are connected to the column 4 by bolts, and the other end of the base 312 and the two sets of side supports 311 are connected to the inner wall of the box 1 by bolts.

[0036] See Figure 4 and Figure 5 The connecting structure 34 includes two sets of connecting rods 341, each set of connecting rods 341 having an insertion hole on one side of its opposite side, and the connecting rods 341 being U-shaped.

[0037] See Figure 4 and Figure 5 A connecting frame 342 is provided in the middle of the two sets of connecting rods 341. Two sets of insertion holes are respectively passed through the two ends of the connecting frame 342. The weight sensor 33 is located at the bottom of the connecting frame 342. The connecting frame 342 and the weight sensor 33 are connected by bolts.

[0038] The weight sensor 33 is bolted to the middle of the base 312. This serves two purposes: firstly, it positions the weight sensor 33, reducing its displacement due to vibration or load impact during weighing; secondly, the weight sensor 33 is installed in the middle of the base 312, placing it at the center of force and reducing off-center load interference caused by installation misalignment, thus establishing a benchmark for the vertical transmission of subsequent forces.

[0039] The bolt connection method allows for fine-tuning of the level of the base 312 during installation, which can compensate for unevenness of the inner wall of the box 1 or the mounting surface of the column 4, and further make the force direction of the weight sensor 33 consistent with the designed vertical direction, thereby improving the weighing accuracy.

[0040] Two sets of side brackets 311 cooperate with the base 312 to form a triangular support structure, and the two ends are respectively connected to the column 4 and the inner side wall of the box 1 by bolts. This two-way fixed design can distribute the load of the weighing system to the column 4 and the box 1, avoid the weight being concentrated on a single point of the base 312, reduce the risk of deformation of the base 312, and reduce the possibility of deformation being transmitted to the weight sensor 33 and affecting the data.

[0041] The symmetrical design of the side bracket 311 further balances the force on the overall structure, reduces the tilting of the installation structure 31 caused by excessive force on one side, indirectly improves the horizontal state of the top weighing plate 32, and reduces the force transmission deviation caused by the tilting of the top weighing plate 32.

[0042] By setting up a double protection system where the base 312 is fixed and connected to the connecting frame 342, the bottom of the weight sensor 33 is stably supported by the base 312, and the top is indirectly connected to the connecting structure 34 through the connecting frame 342. This reduces the load on the top weighing pan 32, or the impact of the object to be weighed directly on the sensor body, reducing fatigue damage caused by direct overload and extending the service life of the sensor.

[0043] The weight sensor 33 is connected to the base 312 and the connecting bracket 342 by bolts. If the sensor needs to be repaired, calibrated or replaced in the future, only the corresponding bolts need to be removed, which greatly reduces maintenance costs and downtime.

[0044] The U-shaped structure provides a certain structural rigidity to the connecting rod 341, which can withstand the load transmitted by the top weighing plate 32 without easily deforming. At the same time, the design of opening the insertion holes on the opposite sides allows the connecting frame 342 to pass through the insertion holes for flexible assembly. The connecting frame 342 can be slightly adjusted horizontally within the insertion holes, which can compensate for slight positional deviations when the top weighing plate 32 is installed, so that the force transmitted to the weight sensor 33 is a vertical load, reducing the possibility of horizontal force interfering with the measurement accuracy.

[0045] The connecting frame 342 has two sets of connecting rods 341 inserted through the holes at both ends. The top indirectly supports the weight of the top weighing plate 32, and the bottom is connected to the weight sensor 33 by bolts. This bridging design can evenly distribute the load of the top weighing plate 32 to the entire connecting frame 342, and then concentrate it to the weight sensor 33, reducing single-point overload caused by excessive local force on the top weighing plate 32, protecting the sensor and improving the uniformity of weighing.

[0046] The intermediate connection logic of the connecting frame 342 eliminates the need for direct alignment between the top weighing pan 32 and the weight sensor 33, reducing the size limitations of the top weighing pan 32. If the top weighing pan 32 needs to be designed for different sizes, it can be adapted to the connecting frame 342 via the connecting rod 341, thus improving the adaptability of the weighing system to items of different sizes.

[0047] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
