[0029] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0030] The following describes embodiments of the present invention in detail, examples of which 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 invention, and should not be understood as limiting the present invention.

[0031] like Figure 1 As shown, this embodiment provides a refrigeration device with a storage rack, specifically a wine cabinet, which includes a cabinet body 1 and a storage rack 2 arranged in the cabinet body 1. The cabinet body 1 defines a storage space, and the storage rack 2 includes a rear end facing the inner wall of the cabinet body 1 and a front end relative to the rear end.

[0032] Cabinet 1 is the main structure of the wine cabinet and can be made of metal or high-strength plastic to ensure its stability and durability. Cabinet 1 features multiple storage spaces for orderly storing wine bottles. The exterior walls of cabinet 1 can be decorated with materials such as glass and wood to enhance its aesthetics and practicality. Cabinet 1 also houses an inner liner, which provides insulation and heat preservation.

[0033] The shelf 2 is provided in the inner liner for placing and fixing objects such as wine bottles. The shelf 2 can be made of wood, metal or high-strength plastic to provide a certain stability and load-bearing capacity. The shelf 2 is divided into a plurality of storage compartments, each of which can store a bottle of wine.

[0034] like Figure 2 and Figure 3 As shown, a motion component 3 is also provided in the wine cabinet, and the storage rack 2 is placed on the motion component 3, with the front end tilted downward to form an inclination angle. The storage rack 2 can extend and retract along the inclination angle, and the inclination angle is not greater than 15°.

[0035] The motion component 3 is a device for supporting the storage rack 2 and enabling it to move along a specific trajectory. The storage rack 2 is mounted on the motion component 3, with the front end tilted downward to form an inclination angle of no more than 15°. In actual application requirements, red wine generally needs to be placed in a wine cabinet. When the red wine is placed along the movement direction of the storage rack 2, it has a better display effect. At this time, the inclination angle is controlled to be no more than 15° to ensure that the red wine bottle can maintain contact with the cork when placed, preventing air from entering the bottle, keeping the cork moist, preventing it from drying and shrinking, ensuring the sealing inside the bottle, avoiding oxidation and deterioration of the wine, effectively extending the shelf life of the red wine, allowing it to age under optimal conditions, and improving the quality of the red wine.

[0036] like Figure 4As shown, the motion assembly 3 includes a damping device 4. As the rack 2 moves outward, the damping device 4 generates a damping force to control the rack 2's descent speed. This damping device 4 is used to generate a control force during the rack 2's outward movement, preventing the rack 2 from sliding rapidly and potentially causing safety hazards. When the user pulls out the rack 2, the torque control of the damping device 4 ensures smooth movement, reducing vibration during the rack 2's movement, protecting the bottles on the rack 2 from damage, maintaining its stability, and enhancing safety and comfort.

[0037] The damping device 4 generates a damping force based on the tilt angle when the rack 2 moves downward, thereby controlling the downward speed of the rack 2. The damping torque of the damping device 4 satisfies the relationship:

[0038]

[0039] Among them, M 扭 is the damping torque, m is the total mass of the wine rack and the wine bottle, g is the acceleration of gravity, θ is the tilt angle of the wine rack, Δ 修正 is the correction force, S is the descending distance of the rack 2, t is the descending time of the rack 2, and D is the pitch circle diameter.

[0040] According to the above relationship, the tilt angle is set to 9° in this embodiment. Taking into account the red wine on the market, each bottle of red wine is about 750ml and weighs about 1.25kg. The weight of the wine rack itself is 2kg. 8 bottles of red wine can be placed on the shelf 2. When the friction is ignored, Δ 修正 The above formula calculates the downward force to be 18 N, and the push-back force required to push the shelf 2 back is also 18 N. The 9° tilt angle ensures that the shelf 2 has appropriate resistance when extended, preventing it from sliding out too quickly, while also providing appropriate push-back force when retracted, thus improving the user experience and reducing the burden on the user when using the wine cabinet.

[0041] In some embodiments of the present invention, the rack 2 may be provided with transversely arranged partitions 21, which are arranged perpendicular to the direction of movement of the rack 2. This transverse arrangement allows wine bottles to remain horizontally placed on the rack 2. Horizontally placed bottles are more stable during movement, avoiding shaking and collisions caused by tilting, thereby reducing the risk of bottle damage or wine leakage. Furthermore, by keeping the bottles horizontal, the wine can be ensured to remain in contact with the cork, preventing air from entering the bottle and preserving the quality and flavor of the wine.

[0042] like Figure 4As shown, the motion component 3 includes a fixing portion 31 and a support member 32. The fixing portion 31 is fixedly arranged on the cabinet body 1, and the support member 32 is slidably arranged on the fixing portion 31 at an inclined angle to the horizontal direction. The storage rack 2 is arranged on the support member 32 and is driven by the support member 32 to extend and retract.

[0043] like Figure 4 and Figure 5 As shown, in this embodiment, the fixing portion 31 is formed with a guide groove 311, and the guide groove 311 is set at an inclined angle to the horizontal direction. The support member 32 is set in the guide groove 311, and the support member 32 is provided with a rack 321. The damping device 4 is a damping gear 41, and the damping gear 41 is engaged with the rack 321.

[0044] The damping device 4 includes a damping gear 41. When the rack 2 moves outward, the damping gear 41 generates a damping force to control the descent speed of the rack 2. The support member 32 supports the rack 2 and bears its weight. On the side of the support member 32 that is not subject to the weight of the rack 2, the support member 32 is provided with a rack 321 that meshes with the damping gear 41.

[0045] The damping gear 41 contains a viscous liquid or employs a specific mechanical structure to provide a damping force when the gear rotates. The support member 32 is provided with an elongated rack 321, distributed along its length. The racks 321, which mesh with gears, are evenly distributed on the surface. The racks 321 mesh with the damping gear 41 in the damping device 4, transmitting the damping effect of the damping gear 41 to the support member 32 through the principle of gear transmission.

[0046] As support member 32 slides outward, it drives rack 2 with it. The rack 321 on the back of support member 32 meshes with the damping gear 41, driving the damping gear 41 to rotate. During rotation, the damping gear 41 generates a damping force through its internal viscous fluid or mechanical structure, creating a torque that acts on rack 2, counteracting its downward force due to gravity and effectively controlling its descent speed.

[0047] Because the rack 321 is located on the side of the support member 32 that is not subject to the gravity of the rack 2, the meshing portion is not directly affected by the gravity of the rack 2. Therefore, during the sliding process, the meshing effect between the rack 321 and the damping gear 41 remains stable and is not disturbed by external forces, ensuring the consistency of the damping effect. Even if heavier items are placed on the rack 2, the meshing effect between the rack 321 and the damping gear 41 can still be maintained. There will be no loosening or poor sliding due to load changes. This not only improves the consistency of the damping effect, but also extends the service life of the rack 321 and the damping gear 41, reducing the frequency of maintenance and replacement due to wear. In addition, by adopting this design, the movement of the entire rack 2 can be made smoother, making the stretching and pushing back process smoother during use.

[0048] In this embodiment, the support member 32 includes a support portion 322, which comprises a support plate 3221, a rack plate 3222, and a connecting plate 3223 connecting the two. The upper end surface of the support plate 3221 supports the storage rack 2, and the upper end surface of the rack plate 3222 is provided with a rack 321. The support portion 322 has a C-shaped longitudinal cross-section. The upper end surface of the support plate 3221 supports the storage rack 2, ensuring that the storage rack 2 can be securely placed above it. The rack plate 3222 is arranged parallel to the support plate 3221 and is provided with a rack 321 on its upper end surface. The connecting plate connects the plate 3223 and the rack plate 3222 to ensure the stability and integrity of the overall structure.

[0049] like Figure 6 and Figure 7 As shown, a plurality of fixing grooves 3224 are provided on the surface of the support plate 3221 , and a protruding clamping member 22 is provided at the bottom of the storage rack 2 , which is fitted into the fixing grooves 3224 .

[0050] The fixing grooves 3224 are distributed across the surface of the support plate 3221. These fixing grooves 3224 can be arranged in varying numbers and positions as needed to accommodate the installation requirements of different racks 2. A clip 22 corresponding to the fixing grooves 3224 is provided at the bottom of the rack 2. The clip 22 protrudes from the bottom of the rack 2 and connects to the support plate 3221 by inserting into the fixing grooves 3224. The clip 22 and the fixing grooves 3224 allow the rack 2 to be easily installed on the support plate 3221 and remain stable after installation. The tight fit between the clips 22 and the fixing grooves 3224 ensures that the rack 2 will not fall off or move during sliding, providing a safe and reliable environment for use. Furthermore, the clip structure facilitates the removal and replacement of the rack 2. To adjust the position of the rack 2 or clean it, simply remove the clip 2 from the fixing grooves 3224, making operation simple and convenient.

[0051] The end of the clip 22 is provided with a stepped protrusion 221, which engages with the area surrounding the fixing groove 3224. The stepped structure of the protrusion 221 allows it to be securely engaged with the area surrounding the fixing groove 3224. The protrusion 221 increases the fixing strength of the clip 22, ensuring that the storage rack 2 will not easily fall off during use.

[0052] In other embodiments of the present invention, the shelf 2 and support plate 3221 can also be secured together using assembly parts such as bolts and nuts, or magnetically. When using an assembly part combination, mounting holes are provided on the support plate 3221, and the shelf 2 is secured to the support plate 3221 using bolts and nuts. This solution provides stronger securing force, but is relatively complex to assemble and disassemble. When using a magnetic connection, a magnetic base is embedded in the support plate 3221, and a magnet is installed at the bottom of the shelf 2. The magnetic attraction secures the shelf 2 to the support plate 3221, while facilitating removal and relocation.

[0053] In this embodiment, the support member 32 further includes a coupling portion 323 , which extends outward from the ends of the support plate 3221 and the rack plate 3222 and is sleeved in the guide groove 311 . The coupling portion 323 moves along the guide groove 311 .

[0054] The joint 323 forms a guiding structure, allowing the support member 32 to slide smoothly in the guide groove 311. The joint 323 extends outward from the end of the support portion 322, allowing the support portion 322 to be independent outside the guide groove 311, thereby reducing friction between different components and extending service life.

[0055] In other embodiments of the present invention, the support member 32 and the fixed portion 31 may also employ a combination of a slide rail and a slider, a bearing and a guide rod, or other similar configurations. In the slide rail and slider configuration, the slide rail is fixed to the fixed portion 31, the slider is mounted on the support member 32, and the slider slides along the slide rail. In the bearing and guide rod configuration, the guide rod is fixed to the fixed portion 31, the linear bearing is mounted on the support member 32, and the linear bearing slides over the guide rod.

[0056] like Figure 6 As shown, the wine cabinet is further provided with a buffer device 5, which includes an elastic member 51. When the rack 2 is extended and moves to a position near the limit, the elastic member 51 applies a force opposite to the extending direction of the rack 2 to slow down the movement speed of the rack 2.

[0057] As the rack 2 extends and nears its limit position, the buffer device 5 cushions its movement, preventing the rack 2 from moving too quickly due to inertia, thereby protecting the bottles and the interior structure of the wine cabinet. As the rack 2 extends outward and approaches its limit position, the elastic member 51 in the buffer device 5 compresses, generating a force in the opposite direction of the rack 2's movement, effectively slowing the rack 2's movement and providing a buffering effect.

[0058] The buffer device 5 and the damping device 4 are respectively arranged at the fixed portion 31 on one side. By arranging the two on both sides of the storage rack 2, the utilization rate of the internal space of the wine cabinet can be optimized, and it is avoided that when the buffer device 5 and the damping device 4 are arranged on both sides of the wine cabinet, too much space on the inner wall of the cabinet body 1 is occupied, thereby effectively utilizing the internal storage space. In addition, the buffer device 5 and the damping device 4 are respectively arranged on one side, so that the functions of the two are independent and do not interfere with each other. The buffer device 5 works when the storage rack 2 approaches the extreme position, and the damping device 4 provides damping force during the entire movement process, distributing the motion control function to the fixed portions 31 on both sides, making each component more compact, simplifying the overall structure, reducing the number and complexity of parts, and thus reducing manufacturing and maintenance costs.

[0059] In this embodiment, the buffer device 5 includes a base 52 fixedly arranged on the storage rack 2, an elastic member 51 is arranged in the base 52, and a blocking structure is provided at the front end of the fixed portion 31. When the storage rack 2 is extended and moves to a position near the limit, the blocking structure prevents the elastic member 51 from continuing to move, exerting resistance to it.

[0060] The buffer device 5 is fixedly arranged at the end of the support member 32. The base 52 has a through cavity. The elastic member 51 is a telescopic rod with a spring sleeve. The telescopic rod is slidably arranged in the through cavity of the base 52. Limiting structures are provided at both ends of the telescopic rod to stop the movement of the telescopic rod.

[0061] In other embodiments, the buffer device may also be a hydraulic buffer, a rubber buffer pad structure, etc., as long as it can play a buffering role.

[0062] like Figure 8 and Figure 9As shown, in this embodiment, the damping device 4 includes a damping gear 41 and a housing 42. The damping gear 41 is arranged in the housing 42. The damping gear 41 includes a bidirectional damping gear 411 and an outer gear 412. The bidirectional damping gear 411 includes a gear portion 4111 and a connecting rod 4112 arranged at the center of the gear portion 4111. An internal damping assembly is provided in the gear portion 4111. The connecting rod 4112 is connected to the internal damping assembly. The outer gear 412 is sleeved on the connecting rod 4112. When the support member 32 extends and moves, the gear portion 4111 enters the restricted position. When the support member 32 retracts and moves, the gear portion 4111 disengages from the restricted position.

[0063] Gear unit 4111 is internally equipped with internal damping components, such as springs and hydraulic fluid, to provide damping force during the rotation of linkage rod 4112, regulating its rotational speed. Linkage rod 4112 connects to and supports outer gear 412. Due to the function of bidirectional damping gear 411, when the gears of bidirectional damping gear 411 are restrained and fixed, outer gear 412 and linkage rod 4112 experience damped motion. When the gears of bidirectional damping gear 411 are in a free-motion state, bidirectional damping gear 411 can move freely without any damping effect.

[0064] The shell 42 forms a accommodating cavity for accommodating the damping gear 41, and a limiting tooth 421 is set on the front wall of the accommodating cavity. The size and shape of the accommodating cavity are designed according to the size and shape of the bidirectional damping gear 411 to ensure that the bidirectional damping gear 411 can move to completely disengage from the limiting tooth 421.

[0065] When the support member 32 extends, the bidirectional damping gear 411 moves toward the side of the limiting tooth 421 of the accommodating chamber, and the gear part 4111 engages with the limiting tooth 421. When the support member 32 retracts, the bidirectional damping gear 411 moves away from the side of the limiting tooth 421 of the accommodating chamber, and the gear part 4111 and the limiting tooth 421 are loosened.

[0066] The damping gear 41 rationally utilizes the damping force, applying it only when needed. By applying damping force during extension, the rack prevents rapid downward movement due to gravity, enhancing user experience and safety. The damping force prevents the rack from rapidly sliding downward due to gravity, preventing wine bottles from being damaged by the violent movement, while also protecting the internal structure of the wine cabinet. No damping force is applied during retraction, making manual retraction easier and more labor-saving, as no additional force is required to overcome the damping.

[0067] The damping device 4 further comprises a baffle 43 covering the housing 42 , the baffle 43 being provided with a guide groove, and a guide portion being provided at the bottom of the linkage rod 4112 , and the guide portion being restricted to move back and forth in the guide groove.

[0068] A guide groove is provided on the baffle 43 , and the shape and size of the guide groove are designed according to the guide portion of the linkage rod 4112 to ensure that the linkage rod 4112 can move back and forth smoothly in the guide groove.

[0069] Baffle 43 covers the housing 42, sealing and protecting the internal components. A guide slot is defined in baffle 43, and a guide portion is provided at the bottom of the linkage rod 4112. The guide portion's shape matches the slot, allowing it to slide freely within the slot. The guide portion is constrained within the slot, limiting the linkage rod 4112's movement to a predetermined range. This ensures a fixed trajectory for the linkage rod 4112, thereby ensuring its stability and preventing deviation or jamming.

[0070] In other embodiments of the present invention, a damping structure such as a hydraulic damper may also be employed. When the shelf 2 is extended, the damping device 4 enters a restricted position, driving the valve body to close, and hydraulic oil flows through the valve body to provide a damping effect. When the shelf 2 is retracted, the damping device 4 leaves the restricted position, driving the valve body to open, and no damping force is generated.

[0071] like Figure 10 and Figure 11 As shown, the storage rack 2 further includes a locking device 6 , which includes a switchable locking state and an open state. When the locking device 6 is in the locked state, the storage rack 2 is fixed thereon. When the locking device 6 is in the open state, the storage rack 2 moves along the support member 32 .

[0072] In this embodiment, the locking device 6 is fixedly arranged on the storage rack 2, which includes a self-locking block 61 with an adjustable position, and the fixed portion 31 is provided with a blocking portion 33. When the self-locking block 61 abuts against the blocking portion 33, it is in a locked state, and when the self-locking block 61 moves and disengages from the blocking portion 33, it is in an open state.

[0073] The self-locking block 61 is a structure with adjustable position, which is provided on the storage rack 2. The blocking portion 33 enables the self-locking block 61 to abut against the blocking portion 33 when it is rotated to a specific angle. At this time, the self-locking block 61 is in close contact with the blocking portion 33, forming a fixed support point to prevent the storage rack 2 from moving. This ensures the stability of the storage rack 2 in the locked state and effectively prevents accidental sliding caused by vibration or external force. When the storage rack 2 needs to be unlocked, the position of the self-locking block 61 is adjusted until it is out of contact with the blocking portion 33. In the open state, the storage rack 2 automatically extends due to gravity or is retracted by the user, making it convenient to take and put items.

[0074] In this embodiment, the locking device 6 also includes a rotating shaft 62 arranged at the bottom of the front end of the rack 2. A self-locking block 61 is provided at one end of the rotating shaft 62 facing the fixed portion 31, and a wrench 63 is fixedly provided at the other end. The wrench 63 drives the self-locking block 61 to rotate, and a groove for accommodating the wrench 63 is provided at the bottom of the rack 2.

[0075] The design of the rotating shaft 62 and the wrench 63 facilitates user operation. The rotating shaft 62 connects the wrench 63 and the self-locking block 61 to achieve motion linkage. The rack 2 can be locked and unlocked by controlling the wrench 63.

[0076] The self-locking block 61 is also equipped with an elastic device 64, which applies an elastic force to the self-locking block 61, keeping it fixed to the blocking portion 33. When the user turns the wrench 63, the elastic force applied by the elastic device 64 is overcome, causing the self-locking block 61 to break away from the blocking portion 33. The elastic force provided by the elastic device 64 automatically maintains the self-locking block 61 in contact with the blocking portion 33, ensuring stability in the locked state. When the user stops turning the wrench 63, the elastic device 64 immediately pushes the self-locking block 61 back into contact with the blocking portion 33, achieving automatic locking. The design of the elastic device 64 requires the user to overcome a certain elastic force to unlock the storage rack 2, preventing the storage rack 2 from sliding due to improper operation.

[0077] In other embodiments of the present invention, the locking device 6 may also be a push-type locking device, a magnetic locking device, or the like. In a push-type locking device, locking and unlocking are achieved by pressing a button located at the front of the shelf 2. The user presses the button to operate the lock, and a return spring provides the return force. In a magnetic locking device, a magnet and a magnetic material are respectively located on the shelf 2 and the fixing portion 31, achieving locking through magnetic force.

[0078] In summary, this embodiment utilizes a buffering device to cushion the rack's movement, preventing it from moving too quickly due to inertia, thereby protecting the bottles and the interior structure of the wine cabinet. As the rack extends outward and approaches its limit, the elastic elements in the buffering device compress, generating a force in the opposite direction of the rack's motion, effectively slowing its movement and providing a buffering effect.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
