Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, specifically to a cabinet based on weighing and visual recognition. Background Technology

[0002] Vending machines used for sales generally require minimal human intervention during normal operation, except for restocking and maintenance. Compared to traditional convenience stores, this significantly reduces labor costs, leading to their increasingly widespread application. Weighing sensors are a common component of these machines, accurately measuring changes in item weight and alerting operators to restock promptly. Currently, weighing sensors are typically fixed to the side panels of the vending machine via support arms, with shelves positioned above the sensors on either side. The connection between the support arms and the side panels experiences significant stress, making the side panels prone to deformation. Utility Model Content

[0003] This invention proposes a door cabinet based on weighing and visual recognition, which solves the problem in related technologies where the weighing sensor is generally fixed to the side panel of the door cabinet by a support arm, and the shelves are set above the weighing sensors on the left and right sides. The connection between the support arm and the side panel is subjected to great force, which can easily cause the side panel to deform.

[0004] The technical solution of this utility model is as follows: a cabinet with open doors based on weighing and visual recognition, the key feature of which is: including,

[0005] Inner side panel,

[0006] A longitudinal positioning plate is disposed on the inner wall of the inner side plate;

[0007] A lower transverse positioning plate is disposed inside the longitudinal positioning plate, and the length direction of the lower transverse positioning plate is arranged along the front-back direction;

[0008] An upper transverse positioning plate is disposed inside the longitudinal positioning plate, and the length direction of the upper transverse positioning plate is arranged along the front-back direction, for supporting the layer plate;

[0009] A weighing sensor is disposed between the upper transverse positioning plate and the lower transverse positioning plate.

[0010] It also includes,

[0011] Vibration damping pads are located between the load cell and the upper transverse positioning plate. The lower end face of the vibration damping pads contacts the upper end face of the load cell, and the upper end face of the vibration damping pads contacts the lower end face of the upper transverse positioning plate. There are at least two vibration damping pads, and all the vibration damping pads are arranged in the front-back direction.

[0012] The positioning rod has its lower end passing through the upper transverse positioning plate and the vibration damping pad, and then threadedly connected to the lower transverse positioning plate.

[0013] It also includes a lower reinforcing rib plate, which is disposed between the lower end face of the lower transverse positioning plate and the longitudinal positioning plate.

[0014] It also includes an upper reinforcing rib plate, which is disposed between the upper end face of the lower transverse positioning plate and the longitudinal positioning plate.

[0015] It also includes,

[0016] The positioning seat has an inner side that passes through the inner side plate and connects to the longitudinal positioning plate, and the outer side of the positioning seat has two positioning protrusions, front and rear.

[0017] A longitudinal reinforcing rod is provided on the outer wall of the inner side plate, and a positioning protrusion is provided on the longitudinal reinforcing rod, with the inner side of the positioning protrusion fitting against the outer side of the longitudinal reinforcing rod.

[0018] An outer side plate is disposed on the outside of the longitudinal reinforcing bar.

[0019] The positioning protrusion and the longitudinal reinforcing rod are detachably connected.

[0020] It also includes,

[0021] A base plate, wherein the outer side plate is disposed above the base plate;

[0022] A positioning frame is disposed above the base plate and located inside the outer side plate, and the inner side plate is disposed outside the positioning frame.

[0023] A horizontal rib is provided on the base plate and located below the positioning frame. The length direction of the horizontal rib is arranged in the left-right direction and is located between the longitudinal reinforcing rods on the left and right sides. There are at least two horizontal ribs. All the horizontal ribs are arranged in the front-back direction. The lower end of the longitudinal reinforcing rod is connected to the horizontal rib located inside it.

[0024] It also includes a protective cover, which is disposed on the positioning frame, with the upper transverse positioning plate and the lower transverse positioning plate located between the protective cover and the longitudinal positioning plate.

[0025] The protective cover and the positioning frame are detachably connected.

[0026] It also includes a protective net, which is disposed between the inner side plate and the positioning frame.

[0027] The working principle and beneficial effects of this utility model are as follows: the longitudinal positioning plate is set on the inner wall of the inner side plate; the lower transverse positioning plate is set inside the longitudinal positioning plate, and the length direction of the lower transverse positioning plate is set along the front-back direction; the upper transverse positioning plate is set inside the longitudinal positioning plate, and the length direction of the upper transverse positioning plate is set along the front-back direction, and is used to support the layer plate; the weighing sensor is set between the upper transverse positioning plate and the lower transverse positioning plate.

[0028] A vertical support structure is constructed by setting longitudinal positioning plates on the inner wall of the inner side panel. These longitudinal positioning plates provide an attachment base for the lower and upper transverse positioning plates, allowing them to form a stable frame within the inner side panel. The lower and upper transverse positioning plates are positioned along their length in the front-to-back direction. This layout allows for better weight distribution from the shelf, preventing weight concentration in any localized area. When items are placed on the shelf, their weight first acts on the shelf, which then transfers the weight to the upper transverse positioning plate. The upper transverse positioning plate distributes the weight to the load cells, which in turn transfer it to the lower transverse positioning plate. The lower transverse positioning plate further distributes the weight to the longitudinal positioning plates, which ultimately distribute the weight across the inner side panel. This effective weight distribution prevents deformation of the inner side panel due to excessive localized stress, resulting in a more stable and reliable overall cabinet structure and reducing the frequency of repairs due to structural damage.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0041] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0042] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Example, refer to Figures 1-5 As an embodiment of this utility model, a door-opening cabinet based on weighing and visual recognition is proposed, including an inner side panel 1, a longitudinal positioning plate 2, a lower transverse positioning plate 3, an upper transverse positioning plate 4, and a weighing sensor 5. The longitudinal positioning plate 2 is disposed on the inner wall of the inner side panel 1; the lower transverse positioning plate 3 is disposed inside the longitudinal positioning plate 2, and its length direction is arranged along the front-back direction; the upper transverse positioning plate 4 is disposed inside the longitudinal positioning plate 2, and its length direction is arranged along the front-back direction, for supporting the shelf 19; the weighing sensor 5 is disposed between the upper transverse positioning plate 4 and the lower transverse positioning plate 3.

[0045] In this embodiment, a vertical support structure is constructed by setting a longitudinal positioning plate 2 on the inner wall of the inner side plate 1. The longitudinal positioning plate 2 provides an attachment base for the lower transverse positioning plate 3 and the upper transverse positioning plate 4, enabling them to form a stable frame inside the inner side plate 1. The lower transverse positioning plate 3 and the upper transverse positioning plate 4 are arranged along the front-to-back direction in their length direction. This layout allows them to better distribute the weight from the shelf 19 and avoid the weight being concentrated in a certain local area. When an item is placed on the shelf 19, the weight of the item first acts on the shelf 19, which then transfers the weight to the upper transverse positioning plate 4. The upper transverse positioning plate 4 distributes the weight to the weighing sensor 5, which then transfers the weight to the lower transverse positioning plate 3. The lower transverse positioning plate 3 further distributes the weight to the longitudinal positioning plate 2, and finally, the weight is distributed to the inner side plate 1 through the longitudinal positioning plate 2. In this way, gravity can be effectively distributed, which can prevent the inner side panel 1 from deforming due to excessive local stress, making the overall structure of the cabinet more stable and reliable, and reducing the number of repairs caused by structural damage.

[0046] Furthermore, such as Figure 2 and Figure 5 As shown, the system also includes vibration damping pads 6 and positioning rods 7. Vibration damping pads 6 are located between the load cell 5 and the upper transverse positioning plate 4. The lower end face of the vibration damping pad 6 contacts the upper end face of the load cell 5, and the upper end face of the vibration damping pad 6 contacts the lower end face of the upper transverse positioning plate 4. There are at least two vibration damping pads 6, arranged in a front-to-back direction. The lower end of the positioning rod 7 passes through the upper transverse positioning plate 4 and the vibration damping pads 6, and is threadedly connected to the lower transverse positioning plate 3. The vibration damping pads 6 act as a buffer, reducing the impact force caused by sudden placement of items or changes in weight. The arrangement of multiple vibration damping pads 6 in a front-to-back direction increases the buffer area and uniformity, making force transmission more stable. The positioning rod 7 limits the movement of the vibration damping pads 6, preventing them from shifting. Furthermore, the threaded connection between the positioning rod 7 and the lower transverse positioning plate 3 facilitates the disassembly and replacement of the vibration damping pads 6.

[0047] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, it also includes a lower reinforcing rib plate 8, which is disposed between the lower end face of the lower transverse positioning plate 3 and the longitudinal positioning plate 2, forming a triangular support structure. This structure can enhance the connection strength between the lower transverse positioning plate 3 and the longitudinal positioning plate 2, and prevent the lower transverse positioning plate 3 from deforming or being damaged due to excessive force.

[0048] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, it also includes an upper reinforcing rib plate 9, which is set between the upper end face of the lower transverse positioning plate 3 and the longitudinal positioning plate 2 to form a triangular support structure. This can enhance the connection strength between the lower transverse positioning plate 3 and the longitudinal positioning plate 2 and prevent the lower transverse positioning plate 3 from deforming or being damaged due to excessive force.

[0049] Furthermore, such as Figure 1 and Figure 4 As shown, it also includes a positioning seat 10, a longitudinal reinforcing rod 11, and an outer plate 12. The inner side of the positioning seat 10 passes through the inner plate 1 and is connected to the longitudinal positioning plate 2. The outer side of the positioning seat 10 has two positioning protrusions 13, one in front and one behind. The longitudinal reinforcing rod 11 is disposed on the outer wall of the inner plate 1, and the positioning protrusions 13 are disposed on the longitudinal reinforcing rod 11, with the inner side of the positioning protrusions 13 fitting against the outer side of the longitudinal reinforcing rod 11. The outer plate 12 is disposed on the outer side of the longitudinal reinforcing rod 11.

[0050] The positioning flange 13, longitudinal reinforcing rod 11, and inner side plate 1 are arranged sequentially from the outside to the inside and are attached together. When the weight of the lower transverse positioning plate 3 is distributed to the longitudinal positioning plate 2, the longitudinal positioning plate 2 can transfer the force to the longitudinal reinforcing rod 11 through the positioning seat 10. The longitudinal reinforcing rod 11 then transfers the force to the inner side plate 1 it is attached to, which can further increase the force-bearing area of ​​the inner side plate 1 and prevent the inner side plate 1 from deforming due to excessive local stress. The outer side plate 12 covers all the components on its inside, making the overall shape more neat and beautiful.

[0051] Furthermore, the locating flange 13 and the longitudinal reinforcing rod 11 are detachably connected. When repair or replacement of parts is required, the individual components can be easily separated, improving maintenance efficiency.

[0052] Furthermore, such as Figure 4 , Figure 6 and Figure 7As shown, the structure also includes a base plate 14, a positioning frame 15, transverse ribs 16, and an outer side plate 12 positioned above the base plate 14. The positioning frame 15 is positioned above the base plate 14 and inside the outer side plate 12, while the inner side plate 1 is positioned outside the positioning frame 15. The transverse ribs 16 are positioned on the base plate 14 and below the positioning frame 15. The length direction of the transverse ribs 16 is along the left-right direction and is located between the longitudinal reinforcing rods 11 on both sides. There are at least two transverse ribs 16, and all transverse ribs 16 are arranged along the front-back direction. The lower end of the longitudinal reinforcing rod 11 is connected to the transverse rib 16 located inside it. The transverse ribs 16 connect the longitudinal reinforcing rod 11 to the base plate 14, thereby connecting the inner side plate 1 to the base plate 14, providing a stable bottom support for the inner side plate 1 and enhancing the overall structural integrity. Figure 9 As shown, the cabinet also includes a cabinet door 20, which is located between the outer side panels 12 on the left and right sides. A camera 21 is installed on the cabinet door 20, which is a key device for the cabinet to realize the visual recognition function.

[0053] Furthermore, such as Figure 8 As shown, it also includes a protective cover 17, which is mounted on the positioning frame 15. The upper transverse positioning plate 4 and the lower transverse positioning plate 3 are both located between the protective cover 17 and the longitudinal positioning plate 2. The protective cover 17 can effectively protect the load cell 5, the lower transverse positioning plate 3, and the upper transverse positioning plate 4 from interference from external factors, ensuring that they can work normally.

[0054] Furthermore, the protective cover 17 and the positioning frame 15 are detachably connected, which facilitates maintenance and cleaning of internal components when needed, thereby improving the convenience of maintenance.

[0055] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, it also includes a protective net 18, which is disposed between the inner side plate 1 and the positioning frame 15. The protective net 18 can support the inner side plate 1, further enhancing the strength and load-bearing capacity of the inner side plate 1.

[0056] 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.
