Description

Technical Field

[0001] This utility model belongs to the field of refrigerator structure technology, specifically relating to a thin-walled component for the back shell of a refrigerator drawer with reinforcing ribs. Background Technology

[0002] Refrigerator drawer back covers, being thin-walled components, are typically injection molded from plastic or other lightweight materials. The design of thin-walled components requires a balance between structural strength and weight. Since refrigerator drawers need to bear certain physical loads during use (such as the weight of stored food and other items), the drawer back cover needs sufficient strength and rigidity to ensure its service life and safety. To improve the strength and rigidity of thin-walled components, reinforcing ribs are often incorporated into the design of the drawer back cover. The function of these ribs is to increase the strength of the local structure, disperse external forces, and prevent deformation or breakage of the thin-walled component during use. Reinforcing ribs are usually grid-like or linear and conform to the overall shape of the thin-walled component, effectively improving the structure's load-bearing capacity and resistance to deformation. Because the working environment of refrigerator drawer back covers is relatively harsh (temperature changes, humidity, etc.), material selection is crucial. Common materials include polypropylene (PP) and polystyrene (PS), which have good low-temperature resistance and corrosion resistance, while being lightweight and easy to injection mold. In terms of molding technology, injection molding is the main production process. Through reasonable mold design and process parameter control, the molding quality of the reinforcing ribs and thin-walled structure can be ensured.

[0003] Patent publication number CN213335136U discloses a refrigerator drawer and a refrigerator, including a drawer frame with an open end for pulling out; a drawer baffle corresponding to the open end; and an adjustment structure disposed between the drawer frame and the drawer baffle, allowing the drawer baffle to close or open the open end by adjusting its position. This patent effectively ensures the increased capacity of the refrigerator drawer, improves the user's storage experience, and guarantees the overall increased capacity and usability of the refrigerator.

[0004] However, the current refrigerator drawers and refrigerators have the following problems: the existing refrigerator drawers do not have a buffer protection device, which makes it easy for the drawer to collide with the inside of the refrigerator when it is pushed into the refrigerator, causing damage to the drawer and the inside of the refrigerator. Therefore, we propose a thin-walled part of the back shell of the refrigerator drawer with reinforcing ribs. Utility Model Content

[0005] The purpose of this utility model is to provide a thin-walled refrigerator drawer back shell with reinforcing ribs, which can solve the problem in the related technology that the existing refrigerator drawers do not have a buffer protection device, which makes the drawer very easy to collide with the inside of the refrigerator when it is pushed into the refrigerator, causing damage to the drawer and the inside of the refrigerator.

[0006] The specific technical solution adopted by this utility model is as follows: A thin-walled refrigerator drawer back shell with reinforcing ribs includes a drawer body, an inner cavity reinforcing rib fixedly connected to the inner wall of the drawer body, a pull-out assembly provided on the side of the drawer body, and a buffer device provided on the side of the drawer body away from the pull-out assembly. The buffer device includes a U-shaped frame, the side of which is fixedly connected to the side of the drawer body away from the pull-out assembly. A linkage assembly is provided on the inner wall of the U-shaped frame, and a buffer pad is fixedly connected to the moving end of the linkage assembly.

[0007] Preferably, the linkage component includes a sliding column, which is slidably mounted on the inner wall of the U-shaped frame. A support plate is fixedly connected to the end of the sliding column away from the drawer body. A buffer spring is provided between the side of the support plate near the U-shaped frame and the outer wall of the U-shaped frame. The side of the buffer pad is fixedly connected to the side of the support plate away from the sliding column. A damping pad is fixedly connected to the side of the drawer body near the sliding column. The support plate is provided at the moving end of the linkage component.

[0008] Preferably, the pull-out assembly includes a pull-out handle, which is fixedly connected to the side of the drawer body away from the buffer device. Both sides of the drawer body are fixedly connected to a horizontal slide bar, and a horizontal slide rail is slidably connected to the outer wall of the horizontal slide bar.

[0009] Preferably, the side of the slide column away from the support plate is curved, and the side of the damping pad away from the drawer body is located on the movement trajectory of the curved side of the slide column away from the support plate.

[0010] Preferably, a friction energy reduction device is provided on the outer wall of the U-shaped frame. The friction energy reduction device includes a linkage slide rod, which is slidably installed on the outer wall of the U-shaped frame. An inclined cone block is fixedly connected to one end of the linkage slide rod near the slide column. A return spring is provided between the side of the inclined cone block near the linkage slide rod and the inner wall of the U-shaped frame. A friction block is fixedly connected to the other end of the linkage slide rod away from the inclined cone block. A friction plate is fixedly connected to the top of the transverse sliding track.

[0011] Preferably, the side of the friction block closest to the friction plate is a rough surface, and the side of the friction plate closest to the friction block is a rough surface.

[0012] Preferably, the inclined surface of the inclined cone block is located on the arc-shaped motion trajectory of the sliding column on the side away from the load-bearing plate, and the rough surface of the friction plate is located on the motion trajectory of the rough surface of the friction block.

[0013] The technical effects achieved by this utility model are as follows: This invention utilizes a buffer device to coordinate the U-shaped frame, sliding column, support plate, buffer spring, buffer pad, and damping pad. The buffer pad first contacts the refrigerator interior and stops moving after contact, while the drawer body continues to move inward. This causes the drawer body to move the damping pad closer to the sliding column, and simultaneously, the drawer body's continued movement inward causes the U-shaped frame to move closer to the support plate. This results in the U-shaped frame applying a compressive force to the buffer spring, and the damping pad's movement towards the sliding column causing it to contact the curved surface of the sliding column. Under the dual unloading force of the buffer spring and damping pad, the kinetic energy is absorbed and dispersed, thus protecting the safety of the drawer body and the refrigerator interior. This prevents the drawer from easily colliding with the refrigerator interior when forcefully pushed in, which could cause damage to the drawer and the refrigerator interior.

[0014] This invention utilizes a friction energy reduction device to coordinate the linkage slide rod, inclined cone block, return spring, friction block, and friction plate. The inclined cone block moves towards the slide column, causing the slide column to apply a force to the inclined surface of the inclined cone block. After receiving this force, the inclined cone block moves towards the friction plate under the restriction of the linkage slide rod. This causes the linkage slide rod to drive the friction block towards the friction plate until it contacts it. When the rough surface of the friction block contacts the rough surface of the friction plate, the friction force restricts the friction, thus absorbing and reducing the kinetic energy of pushing the drawer body, further ensuring the safety of the drawer body and the interior of the refrigerator.

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figure 1-5 As shown, a thin-walled refrigerator drawer back shell with reinforcing ribs includes a drawer body 1, an inner cavity reinforcing rib 2 fixedly connected to the inner wall of the drawer body 1, a pull-out assembly 3 provided on the side of the drawer body 1, and a buffer device 4 provided on the side of the drawer body 1 away from the pull-out assembly 3. The buffer device 4 includes a U-shaped frame 41, the side of the U-shaped frame 41 is fixedly connected to the side of the drawer body 1 away from the pull-out assembly 3, and a linkage assembly is provided on the inner wall of the U-shaped frame 41. A buffer pad 45 is fixedly connected to the moving end of the linkage assembly. The buffer pad 45 is made of a soft, high-temperature resistant material.

[0019] The linkage component includes a slide column 42, which is slidably mounted on the inner wall of the U-shaped frame 41. A support plate 43 is fixedly connected to the end of the slide column 42 away from the drawer body 1. A buffer spring 44 is provided between the side of the support plate 43 near the U-shaped frame 41 and the outer wall of the U-shaped frame 41. The side of the buffer pad 45 is fixedly connected to the side of the support plate 43 away from the slide column 42. A damping pad 46 is fixedly connected to the side of the drawer body 1 near the slide column 42. The support plate 43 is the moving end of the linkage component, which is used to transmit power to the component.

[0020] The pull-out assembly 3 includes a pull-out handle 31, which is fixedly connected to the side of the drawer body 1 away from the buffer device 4. Both sides of the drawer body 1 are fixedly connected to a horizontal slide bar 32. A horizontal slide rail 33 is slidably connected to the outer wall of the horizontal slide bar 32. The horizontal slide rail 33 is installed on the inner wall of the refrigerator.

[0021] The side of the slide column 42 away from the support plate 43 is set with an arc surface, and the side of the damping pad 46 away from the drawer body 1 is located on the movement trajectory of the side of the slide column 42 away from the support plate 43 which is an arc surface. The arc surface setting makes the components move more smoothly during operation. According to the above structure, when a user needs to remove materials from the drawer body 1, the user manually pulls the pull handle 31, causing the drawer body 1 to move towards the user under the constraint of the horizontal slide bar 32 and the horizontal slide rail 33, thus creating a sufficiently large space for material retrieval. After retrieving the materials, the user manually pushes the pull handle 31, causing the drawer body 1 to move in the opposite direction and enter the refrigerator. If the user's pushing energy is too great, the buffer pad 45 will first contact the refrigerator interior and stop moving after contact. However, the drawer body 1 continues to move into the refrigerator, causing the drawer body 1 to... The damping pad 46 moves toward the slide column 42, while the drawer body 1 continues to move toward the refrigerator, which in turn drives the U-shaped frame 41 toward the support plate 43. This causes the U-shaped frame 41 to exert a squeezing force on the buffer spring 44. The movement of the damping pad 46 toward the slide column 42 causes the damping pad 46 to contact the arc surface of the slide column 42. Under the dual unloading force of the buffer spring 44 and the damping pad 46, the kinetic energy is absorbed and dispersed, thereby protecting the safety of the drawer body 1 and the inside of the refrigerator. This prevents the drawer from easily colliding with the inside of the refrigerator when it is forcefully pushed into the refrigerator, which could cause damage to the drawer and the inside of the refrigerator.

[0022] like Figure 1-5 As shown, a friction energy reduction device 5 is provided on the outer wall of the U-shaped frame 41. The friction energy reduction device 5 includes a linkage slide rod 51, which is slidably installed on the outer wall of the U-shaped frame 41. An inclined cone block 52 is fixedly connected to one end of the linkage slide rod 51 near the slide column 42. A return spring 53 is provided between the side of the inclined cone block 52 near the linkage slide rod 51 and the inner wall of the U-shaped frame 41. A friction block 54 is fixedly connected to one end of the linkage slide rod 51 away from the inclined cone block 52. A friction plate 55 is fixedly connected to the top of the horizontal sliding track 33. Both the friction plate 55 and the friction block 54 are made of high wear-resistant material.

[0023] The friction block 54 has a rough surface on the side near the friction plate 55, and the friction plate 55 has a rough surface on the side near the friction block 54. The rough surface can increase the friction between the components.

[0024] The inclined surface of the inclined cone block 52 is located on the arc-shaped motion trajectory of the sliding column 42 away from the load-bearing plate 43, and the rough surface of the friction plate 55 is located on the motion trajectory of the rough surface of the friction block 54, so that the component can be used smoothly in basic applications. According to the above structure, the movement of the U-shaped frame 41 towards the support plate 43 causes the inclined cone block 52 to move towards the slide column 42. The movement of the inclined cone block 52 towards the slide column 42 causes the slide column 42 to apply a force to the inclined surface of the inclined cone block 52. After being subjected to the force, the inclined cone block 52 moves towards the friction plate 55 under the restriction of the linkage slide rod 51. This causes the linkage slide rod 51 to drive the friction block 54 towards the friction plate 55 until it contacts the friction plate 55. When the rough surface of the friction block 54 contacts the rough surface of the friction plate 55, the friction force restricts the friction of the friction block 54, causing the kinetic energy of pushing the drawer body 1 to be absorbed and reduced again, thereby further ensuring the safety of the drawer body 1 and the inside of the refrigerator.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
