[0057] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0058] The present application aims to at least solve the technical problem of inconvenient assembly in the related art. To this end, the present application proposes a shelf assembly and a storage device, which can optimize the assembly process and reduce the risk of the shelf falling out after the assembly is completed.

[0059] Reference below Figure 1-Figure 4 A shelf assembly 1 according to an embodiment of the present application is described.

[0060] like Figure 1 and Figure 2 As shown, the shelf assembly 1 is applied to a storage device, and includes: a slide rail 10 and a shelf 20 .

[0061] The slide rail 10 is a basic track for the movement of the shelf 20 and is fixed on the frame of the storage device. The slide rail 10 is provided with a first roller 110 for reducing the friction of the shelf 20 during the movement and making the movement smoother. The shelf 20 is a main structure for storing items. The shelf 20 is movably installed on the slide rail 10 along the front and rear directions. A guide portion 220 and a second roller 230 are provided which are spaced apart along the front and rear directions. The two work together to enable the shelf 20 to move along the slide rail 10 in the front and rear directions and can be realized under specific operations. For the upward and rearward movement, the first roller 110 is installed on the slide rail 10 and rolls with the guide portion 220 of the shelf 20 to provide an upward driving force when the shelf 20 is assembled. The guide portion 220 is a specific structure on the shelf 20 and is arranged at intervals along the front-to-back direction to contact and roll with the first roller 110 when the shelf 20 moves backward, thereby driving the shelf 20 to move upward and rearward. The second roller 230 is installed on the shelf 20 and rolls with the slide rail 10 to ensure that the shelf 20 moves smoothly on the slide rail 10.

[0062] During normal movement, the shelf 20 moves back and forth on the slide rail 10 through the second roller 230 to store and retrieve items. At this time, the first roller 110 does not directly participate in the movement of the shelf 20. The assembly process mainly involves assembling the shelf 20 onto the slide rail 10. During the process of the shelf 20 being assembled backward on the slide rail 10, as the shelf 20 is pushed backward, the guide portion 220 will gradually approach and contact the first roller 110 on the slide rail 10, and then a rolling fit will be generated between the guide portion 220 and the first roller 110 to drive the shelf 20 to move upward and backward until the guide portion 220 crosses the first roller 110 backward. The rolling fit can not only reduce friction, but also provide an upward component force for the shelf 20 through the rolling action of the first roller 110. The upward component force combined with the backward movement of the shelf 20 can enable the shelf 20 to move along an upward arc trajectory until the guide portion 220 completely crosses the first roller 110, and the shelf 20 is stably installed on the slide rail 10.

[0063] Through the cooperation of the guide part 220 and the first roller 110, the shelf 20 can be automatically adjusted upward during the assembly process without the need for additional manual operation or tools. At the same time, the stability of the assembly process can be maintained to prevent the shelf 20 from shaking or getting stuck. The second roller 230 can ensure the smooth movement of the shelf 20 on the slide rail 10.

[0064] Some storage devices are provided with shelves 20 for placing goods. The shelves 20 are deep and heavy, and it is laborious to assemble them into the whole machine. There is also a risk of the shelves 20 falling out after assembly. The present application optimizes the assembly process of the shelves 20, and can reduce the risk of the shelves 20 falling out after assembly.

[0065] According to the shelf assembly 1 provided in the embodiment of the present application, through the reasonable structural layout and coordination among the slide rail 10, the shelf 20, the guide portion 220, the first roller 110 and the second roller 230, the shelf 20 can be flexibly, stably and conveniently moved and assembled on the slide rail 10, and the first roller 110 is installed on the slide rail 10, and the second roller 230 is installed on the shelf 20, which can optimize the assembly process of the shelf 20, reduce the risk of the shelf 20 falling out after assembly is completed, and improve work efficiency.

[0066] In some embodiments, Figure 3 As shown, the slide rail 10 includes an upper baffle 120, a side plate 130 and a lower baffle 140 connected in sequence. The upper baffle 120 and the lower baffle 140 are arranged opposite to each other and are both connected to the inner side of the side plate 130. The shelf 20 has an upper flange 211. The first roller 110 is installed on the side plate 130 and is suitable for rolling cooperation with the lower surface of the upper flange 211. The second roller 230 is suitable for rolling cooperation with the upper surface of the lower baffle 140.

[0067] The upper baffle plate 120 is located above the slide rail 10, opposite to the lower baffle plate 140, and both are connected to the inner side of the side plate 130, which can prevent the shelf 20 from slipping out of the slide rail 10 upward during movement, and can also serve as a stop point for the upward movement of the shelf 20. The side plate 130 connects the upper baffle plate 120 and the lower baffle plate 140 to form the two side boundaries of the slide rail 10, which can provide an installation position for the first roller 110 and ensure the lateral stability of the shelf 20 during movement. The lower baffle plate 140 is located below the slide rail 10, opposite to the upper baffle plate 120. The upper surface of the lower baffle plate 140 can provide a rolling surface for the second roller 230, ensuring that the shelf 20 moves smoothly on the slide rail 10.

[0068] The shelf 20 also has an upper flange 211, which can be a structure extending along the edge of the shelf 20 toward the slide rail 10, and interacts with the upper baffle 120 and the first roller 110 of the slide rail 10. The lower surface of the upper flange 211 can roll with the first roller 110. In the process of the shelf 20 being assembled backward on the slide rail 10, the contact between the upper flange 211 and the first roller 110 can gradually push the shelf 20 to move upward and backward until the guide portion 220 crosses the first roller 110 and is stably in place. The second roller 230 is installed on the side of the shelf 20 and rolls with the upper surface of the lower baffle 140 of the slide rail 10, which can reduce the friction resistance of the shelf 20 during movement and enable the shelf 20 to slide along the slide rail 10 more easily.

[0069] It can be understood that the slide rail 10 includes an upper baffle 120, a side plate 130 and a lower baffle 140 connected in sequence to form a track structure with a semi-closed cross-section, which can enhance the strength and stability of the slide rail 10 and provide clear guidance and restriction for the movement of the shelf 20.

[0070] In some embodiments, Figure 3 and Figure 4 As shown, the distance from the top surface of the first roller 110 to the lower surface of the upper baffle 120 is greater than the distance from the bottom surface of the second roller 230 to the upper surface of the upper flange 211. During the process of the shelf 20 being assembled backward on the slide rail 10, the second roller 230 is suitable for rolling cooperation with the first roller 110.

[0071] During the process of backward assembly of the shelf 20, the second roller 230 is suitable for rolling cooperation with the first roller 110, that is, at a certain stage, the second roller 230 will contact the first roller 110, and the two will roll together to assist the movement or positioning of the shelf 20. The distance from the top surface of the first roller 110 to the lower surface of the upper baffle 120 is greater than the distance from the bottom surface of the second roller 230 to the upper surface of the upper flange 211, that is, when the second roller 230 rolls with the first roller 110, the second roller 230 is above the first roller 110.

[0072] In the initial stage, the shelf 20 is pushed to move backward, and the second roller 230 first contacts and rolls with the lower baffle 140 of the slide rail 10, while the upper flange 211 gradually approaches the first roller 110, but has not yet contacted. In the intermediate stage, as the shelf 20 continues to move backward, the distance between the upper flange 211 and the first roller 110 gradually decreases. At a certain moment, the second roller 230 contacts the first roller 110 and starts to roll together. In the final stage, when the shelf 20 moves to the appropriate position, the shelf 20 is stably positioned on the slide rail 10.

[0073] It can be understood that the second roller 230 and the first roller 110 are rollingly matched, and the second roller 230 is above the first roller 110 to assist in the movement or positioning of the shelf 20.

[0074] In some embodiments, the shelf 20 has a replenishment posture, in which the guide portion 220 is located in front of the first roller 110 , the shelf 20 tilts downward from back to front, and the rear end of the shelf 20 abuts against the lower surface of the upper baffle 120 .

[0075] In the replenishment posture, the guide portion 220 is located in front of the first roller 110 and is not in direct contact with the first roller 110, but is located at a certain position in front of it. The shelf 20 tilts downward from the back to the front, and the rear end of the shelf 20 abuts against the lower surface of the upper baffle 120, which can ensure the stability of the shelf 20 in the replenishment posture and prevent the shelf from overturning during the replenishment process. The upper baffle 120, as a part of the slide rail 10, can provide a solid support point for the shelf 20 to prevent the shelf 20 from moving or tipping over due to the weight of the goods or improper operation during the replenishment process.

[0076] After the goods in shelf 20 are sold out, shelf 20 needs to be pulled out for replenishment. In related technologies, most solutions require shelf 20 to be taken out as a whole to complete the replenishment operation. The shelf 20 of the present application can be pulled out a certain distance for replenishment, and there is no need to separate the shelf 20 from the aisle.

[0077] It is understandable that the replenishment posture of the shelf 20 can make the replenishment process more convenient, efficient and safer through reasonable structural layout and tilt design.

[0078] In some embodiments, Figure 5 and Figure 7 As shown, the guide portion 220 has a guide surface 221 and a limiting surface 222. The guide surface 221 is inclined downward from back to front, the lower end of the limiting surface 222 is connected to the lower end of the guide surface 221, and the limiting surface 222 extends vertically or backward from the lower end to the upper end.

[0079] The guide surface 221 is inclined downward from the back to the front. When the shelf 20 is assembled backward on the slide rail 10, the guide surface 221 can roll or slide with the first roller 110. As the shelf 20 continues to move backward, the guide surface 221 can gradually guide the shelf 20 to move along a predetermined trajectory and may provide an upward component force to help the shelf 20 cross the first roller 110. The limiting surface 222 is at the same height as the guide surface 221 and is connected to the lower end of the guide surface 221.

[0080] The limiting surface 222 extends vertically or backward from the lower end to the upper end, and mainly serves to limit the moving range of the shelf 20. During the backward assembly of the shelf 20, when the guide portion 220 crosses the first roller 110, the limiting surface 222 contacts the first roller 110, thereby preventing the shelf 20 from continuing to move backward, ensuring that the shelf 20 can be accurately positioned at the predetermined position on the slide rail 10. The limiting surface 222 can also increase the stability of the guiding portion 220. When the shelf 20 moves on the slide rail 10, the limiting surface 222 can prevent the guiding portion 220 from being deformed or displaced due to lateral force, thereby ensuring that the shelf 20 can move smoothly.

[0081] It can be understood that the guide portion 220 can make the shelf 20 more stably positioned on the slide rail 10, the guide surface 221 can provide guidance and support during the movement, and the limiting surface 222 can ensure the stability and accuracy of the shelf 20 after reaching the predetermined position, thereby improving the loading and unloading efficiency of the shelf 20 and reducing the error and damage risk during operation.

[0082] In some embodiments, Figure 5 and Figure 7 As shown, the shelf 20 further includes a stopper 214 , which is located at the front side of the guide portion 220 and is spaced apart from the guide portion 220 to form an accommodating cavity 215 , and the first roller 110 is suitable for being located in the accommodating cavity 215 .

[0083] The main function of the stop portion 214 is to serve as a stop point for the shelf 20 to move forward on the slide rail 10. When the shelf 20 moves forward, such as when it recovers from a replenishment posture to a normal use posture, the stop portion 214 can prevent the shelf 20 from continuing to move forward, thereby ensuring that the shelf 20 can be accurately positioned at a predetermined position on the slide rail 10.

[0084] The stop portion 214 is located at the front side of the guide portion 220 and is separated from the guide portion 220 to form an accommodating cavity 215 for accommodating the first roller 110. When the shelf 20 is installed, the first roller 110 is located in the accommodating cavity 215 to fix the shelf 20 and the slide rail 10, and the stop portion 214 and the guide portion 220 together form a stable supporting structure. When the shelf 20 is in different postures or is subjected to external forces, the supporting structure can maintain the stability and balance of the shelf 20 and prevent the shelf 20 from tipping over or shifting.

[0085] During the movement of the shelf 20, the guide portion 220 first contacts the first roller 110 and guides the shelf 20 to move along the slide rail 10. When the shelf 20 moves to a predetermined position, the stop portion 214 can prevent the shelf 20 from continuing to move forward and allow the first roller 110 to stay in the accommodating cavity 215. At this time, the shelf 20 is in a stable state.

[0086] It can be understood that the stopper 214 is spaced apart from the guide portion 220 to form a receiving cavity 215 for receiving the first roller 110 , so that the shelf 20 can be installed stably.

[0087] In some embodiments, Figure 5 As shown, the stopper 214 is a plate and is formed by bending a portion of the shelf 20 .

[0088] The stopper 214 is formed by bending a portion of the shelf 20 and is made of the same material as the other portions of the shelf 20, which helps to reduce stress concentration or deformation problems caused by different materials and can improve the overall strength and stability of the shelf 20. At the same time, the stopper 214 formed by the bending is tightly connected to the shelf 20 and does not require additional connectors or fasteners, which can save material costs and simplify the manufacturing process and assembly process.

[0089] The stopper 214 is designed and manufactured as a part of the whole shelf 20, and can form a close cooperation relationship with the guide part 220, the roller and other components, which helps to ensure the accuracy and stability of the shelf 20 during the movement and positioning process. Strengthening treatment is performed at the bending part, such as adding reinforcing ribs or using thicker materials, which can improve the stability and durability of the stopper 214.

[0090] It can be understood that by bending a portion of the shelf 20 to form the stopper 214 , the material and structural characteristics of the shelf 20 are fully utilized, and the overall performance and reliability of the shelf 20 can be improved.

[0091] In some embodiments, Figure 4 As shown, the shelf 20 includes: a shelf body 240 and a support frame 210 , the support frame 210 is installed on the side of the shelf body 240 , and the guide portion 220 and the second roller 230 are both installed on the support frame 210 .

[0092] The shelf body 240 is the main load-bearing part of the shelf 20, used to support and store goods. It is usually made of solid metal materials, such as steel, aluminum, etc., to ensure that it can bear the weight of the goods and meet various usage conditions. The shelf body 240 can also be provided with beams, partitions or other components for fixing the goods.

[0093] The support frame 210 is installed on the side of the shelf body 240, and mainly plays the role of supporting and fixing other components. The guide part 220 and the second roller 230 are both installed on the support frame 210 and fixed on the shelf body 240 together with the support frame 210, thereby forming a stable moving and positioning mechanism, wherein the guide part 220 is responsible for guiding the moving trajectory of the shelf 20 on the slide rail 10, and the second roller 230 cooperates with the first roller 110 to realize the rolling movement of the shelf 20.

[0094] When the shelf 20 needs to move, the guide part 220 first contacts the first roller 110 on the slide rail 10 and guides the shelf 20 to move along a predetermined track. At the same time, the second roller 230 contacts the surface of the slide rail 10 or other rolling parts to achieve rolling movement. During the movement, the support frame 210 provides stable support and fixation for the guide part 220 and the second roller 230 to ensure smooth movement and accurate positioning of the shelf 20.

[0095] It can be understood that by dividing the shelf 20 into two parts, a shelf body 240 and a support frame 210, and installing components such as a guide portion 220 and a second roller 230 on the support frame 210, the structure of the shelf 20 can be made clearer and more modular, thereby improving the overall performance and reliability of the shelf 20.

[0096] In some embodiments, Figure 5 As shown, the support frame 210 includes: a main body plate 212 , an upper flange 211 and a lower flange 213 .

[0097] The main plate 212 is the core part of the support frame 210, and is used to provide a plane for installing the guide part 220 and the second roller 230. The guide part 220 and the second roller 230 can be fixed on the main plate 212 by bolts, welding or other means. The upper flange 211 is connected to the upper end of the main plate 212 and folded outward. The lower surface of the upper flange 211 can roll with the first roller 110. When the shelf 20 moves on the slide rail 10, the first roller 110 rolls along the lower surface of the upper flange 211, thereby realizing the smooth movement of the shelf 20. The outward folding of the upper flange 211 can also prevent dust, debris, etc. from entering the interior of the support frame 210, keeping it clean and running smoothly.

[0098] The lower flange 213 is connected to the lower end of the main plate 212 and folded inward to be tightly connected to the shelf body 240. The lower flange 213 can be installed on the shelf body 240 by bolts, welding or other fixing methods to provide stable support for the support frame 210. At the same time, the inward folding of the lower flange 213 can also increase the contact area between the support frame 210 and the shelf body 240, thereby improving the firmness and stability of the connection.

[0099] During the movement of the shelf 20, the first roller 110 rolls along the lower surface of the upper flange 211 to guide the shelf 20 to move along the slide rail 10, and at the same time, the second roller 230 contacts the slide rail 10 or other rolling components to achieve rolling movement.

[0100] It can be understood that the support frame 210 provides a stable installation platform for the guide part 220 and the second roller 230 through the coordinated action of the main plate 212, the upper flange 211 and the lower flange 213, and ensures a stable connection and smooth movement between the shelf 20 and the slide rail 10.

[0101] The embodiments of the present application are described in detail below.

[0102] The shelf assembly 1 is applied to storage equipment, and includes a slide rail 10 and a shelf 20 .

[0103] The slide rail 10 includes an upper baffle 120 , a side plate 130 and a lower baffle 140 connected in sequence. The upper baffle 120 and the lower baffle 140 are arranged opposite to each other and are both connected to the inner side of the side plate 130 . The first roller 110 is installed on the side plate 130 .

[0104] The shelf 20 includes a shelf body 240 and a support frame 210. The support frame 210 is installed on the side of the shelf body 240, and includes a main plate 212, an upper flange 211 and a lower flange 213. The guide portion 220 and the second roller 230 are both installed on the main plate 212. The upper flange 211 is connected to the upper end of the main plate 212 and is folded outward. The lower flange 213 is connected to the lower end of the main plate 212 and is folded inward. The lower flange 213 is connected to the shelf body 240.

[0105] The guide portion 220 has a guide surface 221 and a limiting surface 222, which is inclined downward from the back to the front. The lower end of the limiting surface 222 is connected to the lower end of the guide surface 221, and the limiting surface 222 extends vertically or backward from the lower end to the upper end. The shelf 20 also includes a stop portion 214, which is a plate body and is formed by bending a part of the shelf 20. It is located on the front side of the guide portion 220 and is separated from the guide portion 220 to form a accommodating cavity 215. The first roller 110 is suitable for being located in the accommodating cavity 215.

[0106] The installation process of shelf 20 is divided into two stages.

[0107] In the first stage, the shelf 20 begins to be installed. The shelf 20 is first pushed backward to a specific position, that is, the first roller 110 installed on the slide rail 10 is just below the second roller 230 installed on the shelf 20, and the first roller 110 and the second roller 230 are in contact with each other, ready to start rolling cooperation.

[0108] In the second stage, the shelf 20 is pushed backward and assembled onto the slide rail 10, and the lower surface of the upper flange 211 first contacts the first roller 110. As the shelf 20 continues to move backward, the first roller 110 begins to roll on the lower surface of the upper flange 211, gradually approaches and contacts the guide portion 220, and the second roller 230 rolls with the upper surface of the lower baffle 140.

[0109] In the third stage, a rolling cooperation is generated between the guide portion 220 and the first roller 110. The rolling characteristics of the roller and the inclined design of the guide portion 220 provide an upward component force for the shelf 20. The component force is combined with the backward movement of the shelf 20, so that the shelf 20 can move along an upward arc trajectory. At the same time, the second roller 230 and the upper surface of the lower baffle 140 are in rolling cooperation to ensure the smoothness and stability of the shelf 20 during the movement. Finally, the guide portion 220 crosses the first roller 110 and is stably positioned on the slide rail 10, that is, the shelf 20 moves to the appropriate position.

[0110] The embodiment of the present application further provides a storage device, which includes: a box body and a shelf assembly 1.

[0111] The box is the main part of the storage device, which can form a compartment to protect the items stored in it from the external environment, such as dust, moisture, insects, etc. The box is usually made of strong materials such as metal or plastic to ensure its structural strength and durability.

[0112] The slide rail 10 is installed on the side wall of the compartment so that the shelf assembly 1 can move smoothly in a specific direction in the compartment. The slide rail 10 is usually made of wear-resistant and corrosion-resistant materials to ensure its stability and reliability in long-term use. The shelf assembly 1 is installed on the slide rail 10 and moves in the compartment through the slide rail 10. The shelf 20 can be installed or pulled out by pushing or pulling the shelf assembly 1.

[0113] It is understandable that the synergistic effect of the slide rails 10 and the rollers and other components can ensure the smooth movement and accurate positioning of the shelf assembly 1, thereby improving the safety and durability of the storage device.

[0114] In some embodiments, the storage device is a vending machine and includes: a refrigeration system for providing cold air to the compartment so that the temperature of the compartment is suitable to be below zero degrees.

[0115] The storage device in this embodiment can be a vending machine, which is mainly used to store and sell goods that need to be preserved at low temperatures, such as ice cream, cold drinks, frozen foods, etc., without human intervention. It is usually installed in public places, such as shopping malls, schools, airports, subway stations, etc. The refrigeration system is one of the core components of the vending machine, which is responsible for providing cold air to the compartment where the goods are stored in the vending machine. By circulating the refrigerant, the refrigeration system can absorb and take away the heat in the compartment, thereby reducing the temperature of the compartment and ensuring that the temperature of the compartment of the vending cabinet can be lower than 0 degrees Celsius, for example, it can be 0°C to -30°C.

[0116] The refrigeration system usually consists of four main parts: compressor, condenser, expansion valve and evaporator. The compressor compresses the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas, and then sends it to the condenser for cooling and liquefaction. The liquefied refrigerant enters the evaporator after the pressure is reduced by the expansion valve, evaporates in the evaporator and absorbs heat, thereby reducing the temperature of the compartment. The evaporated refrigerant is sucked into the compressor again, starting a new cycle.

[0117] It is understandable that when a vending machine is used as a storage device, its built-in refrigeration system can accurately control the temperature of the compartment, maintain the low temperature environment of the compartment, and adjust the temperature range of the compartment as needed by adjusting the working state of the refrigeration system to ensure that the goods are in the best storage conditions.
