Description

Technical Field

[0001] This application relates to the technical field of drawers, and more specifically, to a high side panel applied to a drawer. Background Technology

[0002] In an environment of rapid urbanization and fast-paced lifestyle, modular drawers offer advantages such as flexible assembly and short assembly time. A drawer consists of a bottom panel, front panel, back panel, and side panels. The height of these panels determines the height of items the drawer can hold. Low and medium-sized drawers cannot meet the needs of taller items, requiring increased side panel height to accommodate the installation space.

[0003] In existing technology, high-drawer side panels often use double-walled side panels. Double-walled side panels can enhance the overall strength of the side panels, supporting heavier items and reducing overall drawer deformation. However, due to the height of the side panels, when double-walled side panels are molded as a single piece, the unfolded length of the material is too large, making the side panels prone to deformation. This causes the mating surfaces of the side panels and cabinet guide rails to become non-parallel, disrupting the overall aesthetic consistency of the drawer during installation. In more serious cases, side panel deformation can lead to guide rail system failure, a sudden increase in running resistance, and phenomena such as jamming, skipping, or even derailment, causing the drawer to tip over and injure the user. Utility Model Content

[0004] This application provides a high side panel for drawers that can effectively reduce deformation of the high side panel, ensure normal operation of the high side panel, extend the service life of the drawer, and reduce the occurrence of accidents.

[0005] This application provides a technical solution for a high side panel of a drawer, using the following approach:

[0006] A high side panel for use in a drawer, comprising:

[0007] The side panel body includes a first plate, a second plate, and a mounting bracket. The mounting bracket is disposed on the same side of the first plate and the second plate to fix the first plate and the second plate relatively. An installation chamber is provided between the first plate and the second plate. A first bending portion is provided on the side of the first plate closer to the second plate, and a second bending portion is provided on the side of the second plate closer to the first plate. Both the first bending portion and the second bending portion are bent toward the direction inside the installation chamber.

[0008] A first connector is disposed in the mounting cavity along the length direction perpendicular to the first bend. One end of the first connector is limited and connected to the first bend and the second bend, and the other end of the first connector is connected to the mounting bracket.

[0009] The second connector is located at the rear end of the side plate body and is used to connect with the tail plate.

[0010] In some technical solutions, the first plate and / or the second plate are provided with a snap-fit ​​groove, and one end of the first connector is provided with a snap-fit ​​part that mates with the snap-fit ​​groove, and the snap-fit ​​part snaps into the snap-fit ​​groove;

[0011] The other end of the first connector is provided with a fixing part, which is fixedly connected to the mounting bracket by bolts.

[0012] In some technical solutions, a stepped portion is provided in the middle region of the first connector, and the stepped portion is provided with a first stepped platform and a second stepped platform. The first stepped platform abuts against the first plate, and the second stepped platform abuts against the second plate.

[0013] In some technical solutions, the second connector includes a first connecting part and a second connecting part, one end of the first connecting part is fixedly connected to the mounting bracket by bolts, and the second connecting part is snapped into the first plate or the second plate.

[0014] In some technical solutions, the second connecting part is provided with a first elastic hook, and the first plate or the second plate is provided with a first connecting groove corresponding to the first elastic hook. The first elastic hook has a high end, which can be pressed and deformed when it comes into contact with the first plate or the second plate, so as to enter into the first connecting groove and engage with the first connecting groove.

[0015] In some technical solutions, a first guide slope is provided at the end of the second connecting part near the side plate body, which facilitates the second connecting part entering the mounting cavity.

[0016] In some technical solutions, the end faces of the first plate and the second plate facing the second connector are provided with multiple protrusions, the second connector is provided with a flange along the length direction, and the flange is provided with multiple second connecting grooves corresponding to the protrusions. The protrusions and the second connecting grooves are provided one-to-one. When the second connector is installed on the side plate body, the protrusions are engaged in the second connecting grooves.

[0017] In some technical solutions, a fixing member is also included. The fixing member is provided with a limiting groove. The fixing member is disposed in the mounting cavity, and the first bent portion and the second bent portion are located in the limiting groove to fix the first plate and the second plate.

[0018] In some technical solutions, the fixing member is disposed on the side of the first connector away from the second connector, and the fixing member is provided with a plug-in portion on the side of the first connector. The plug-in portion is provided with a second guide slope, which facilitates the fixing member entering the mounting cavity.

[0019] In some technical solutions, the plug-in portion is provided with a second elastic hook, and the first connector is provided with a relief groove that cooperates with the second elastic hook. When the fixing member is installed in the mounting chamber, the second elastic hook is located in the relief groove, so that the fixing member and the first connector are relatively fixed.

[0020] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0021] The first and second panels form a double-layer structure. On one hand, this creates an installation chamber to accommodate the first and second connectors, reducing their impact on drawer space. On the other hand, the double-layer panels, together with the first and second connectors, form an I-beam structure. The sum of the moments of inertia of the two panels increases the overall bending stiffness, enhancing the strength of the high side panel and reducing the possibility of deformation. Simultaneously, the first connector is located at the front end of the side panel, and the second connector at the rear end. The cooperation of the first and second connectors at both ends of the side panel constrains the high side panel, preventing deformation from heavy objects falling forward. This ensures the high side panel operates normally, extends the drawer's lifespan, and reduces the occurrence of accidents. Attached Figure Description

[0037] This application provides a high side panel for drawers that can effectively reduce deformation of the high side panel, ensure normal operation of the high side panel, extend the service life of the drawer, and reduce the occurrence of accidents.

[0038] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and not all of them.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0039] For ease of understanding, the following is a brief description of the environment in which the high side panels are used in the embodiments of this application. The two high side panels, together with the front panel, the bottom panel and the tail panel, form a drawer. The end of the high side panel closer to the front panel is the front end, and the end of the high side panel closer to the tail panel is the rear end.

[0040] Please see Figure 1 and Figure 2 This is one embodiment of a high side panel applied to a drawer in this application. The high side panel includes a side panel body 1, a first connecting member 2, and a second connecting member 3. The first connecting member 2 and the second connecting member 3 are arranged along the length direction of the side panel body 1. The first connecting member 2 is located at the front end of the side panel body 1, and the second connecting member 3 is located at the rear end of the side panel body 1. The first connecting member 2 and the second connecting member 3 cooperate to constrain the two ends of the side panel body 1, thereby reducing the possibility of deformation of the side panel body 1.

[0041] Please see Figure 2 and Figure 3Specifically, the side panel body 1 includes a first plate 11, a second plate 12, and a mounting bracket 13. The mounting bracket 13 is disposed on the same side of the first plate 11 and the second plate 12 to fix the first plate 11 and the second plate 12 relatively. A mounting chamber 14 is provided between the first plate 11 and the second plate 12. A first bending portion 111 is provided on the side of the first plate 11 closest to the second plate 12, and a second bending portion 121 is provided on the side of the second plate 12 closest to the first plate 11. The first bending portion 111 and... The second bends 121 are all bent towards the direction of the mounting chamber 14. The first bends 111 and the second bends 121 can enhance the strength of the plate to a certain extent. The first connector 2 is disposed in the mounting chamber 14 along the length direction perpendicular to the first bend 111. One end of the first connector 2 is limited and connected to the first bend 111 and the second bend 121, and the other end of the first connector 2 is connected to the mounting bracket 13. The second connector 3 is disposed at the rear end of the side plate body 1 for connection with the tail plate. It can be understood that the first plate 11 and the second plate 12 constitute a double-layer structure. On the one hand, it can form the mounting chamber 14 to accommodate the first connector 2 and the second connector 3, reducing the space occupied by the first connector 2 and the second connector 3 in the drawer. On the other hand, the double-layer plate body, together with the first connector 2 and the second connector 3, forms an I-beam structure. The moments of inertia of the two plates are added together, and the overall bending stiffness is improved, enhancing the strength of the high side plate and making the high side plate less prone to deformation due to the falling of heavy objects.

[0042] In this embodiment, the mounting bracket 13 is arranged along the length of the high side plate. The mounting bracket 13 is elongated and has two mutually perpendicular side walls. One side wall is parallel to the first plate 11 and the other side wall is parallel to the second plate 12. The first plate 11 and the second plate 12 are locked to the mounting bracket 13 by bolts.

[0043] Please see Figure 4 and Figure 5The first plate 11 and / or the second plate 12 are provided with snap-fit ​​grooves 15. One end of the first connector 2 is provided with a snap-fit ​​part 21 that mates with the snap-fit ​​groove 15, and the snap-fit ​​part 21 snaps into the snap-fit ​​groove 15. The other end of the first connector 2 is provided with a fixing part 22, and the fixing part 22 is fixedly connected to the mounting bracket 13 by bolts. In this embodiment, the snap-fit ​​part 21 is L-shaped, and the snap-fit ​​groove 15 is disposed at the front end of the first plate 11. In other embodiments, the snap-fit ​​groove 15 can be disposed at the front end of the second plate 12, or simultaneously disposed on the first plate 11 and the second plate 12. It is worth mentioning that when only one end of the first connector 2 is fixed to the mounting bracket 13 by bolts, the other end of the first connector 2 will deform outward under force. Therefore, it is necessary to limit the upper end of the first connector 2 without affecting the appearance of the high side plate. It is understandable that when the first connector 2 is installed in the installation chamber 14, the operating snap-fit ​​part 21 snaps into the snap-fit ​​groove 15, and the fixing part 22 is fixed to the mounting bracket 13 by bolts, thereby constraining both sides of the side plate body 1 in the width direction. After the first connector 2 is subjected to force, it deforms outward. At the same time, the first plate 11 and the second plate 12 interact with the first connector 2, effectively reducing the deformation rate of the first plate 11 and the second plate 12.

[0044] Furthermore, a stepped portion 23 is provided in the middle region of the first connector 2. The middle region is the area between the snap-fit ​​end and the fixed end. The stepped portion 23 is provided with a first stepped platform 231 and a second stepped platform 232. The first stepped platform 231 abuts against the first plate 11, and the second stepped platform 232 abuts against the second plate 12. In this embodiment, the first stepped platform 231 is formed by bending a portion of the stepped portion 23 structure, creating a height difference between it and the second stepped platform 232 without increasing the overall weight of the first connector 2, so as to realize the function of the first stepped platform 231 supporting the first plate 11. By supporting the first plate 11 and the second plate 12 with the first stepped platform 231 and the second stepped platform 232, the strength of the high side plate can be enhanced in the thickness direction of the side plate body 1, further reducing the possibility of deformation of the high side plate.

[0045] Please see Figure 6 and Figure 7The second connector 3 has the same length direction as the first connector 2. The second connector 3 includes a first connecting part 31 and a second connecting part 32. One end of the first connecting part 31 is fixedly connected to the mounting bracket 13 by bolts, and the second connecting part 32 is snapped into the first plate 11 or the second plate 12. By constraining the two ends of the side plate body 1 with the first connecting part 31 and the second connecting part 32, along the width direction of the side plate body 1, the second connector 3 upgrades the point force to the line force, which can distribute the concentrated force generated by the weight of the tail plate, guide rail, and drawer to the entire connector, and then evenly transfer it to the first plate and the second plate, avoiding local tearing or crushing of the single plate.

[0046] Specifically, the second connecting part 32 is provided with a first elastic hook 321, and the first plate 11 or the second plate 12 is provided with a first connecting groove 16 corresponding to the first elastic hook 321. The first elastic hook 321 has a high end 3211, which can be pressed and deformed when in contact with the first plate 11 or the second plate 12, so as to enter into the first connecting groove 16 and engage with it. In this embodiment, the first connecting groove 16 is disposed at the rear end of the first plate 11. In other embodiments, the first connecting groove 16 can be disposed at the rear end of the second plate 12, or simultaneously disposed on the first plate 11 and the second plate 12. The elastic deformation stroke of the high end 3211 can compensate for manufacturing tolerances or plate thickness differences of 0.5-1 mm. The first elastic hook 321 can still fully rebound in the groove, avoiding misalignment or failure to fit due to dimensional deviations, and improving the first-pass yield.

[0047] Understandably, during insertion, the high end 3211 of the first elastic hook 321 is first pressed down by the edge of the second plate 12, forming a ramp guide. When it reaches the first connecting groove 16, the high end 3211 instantly rebounds and hooks onto the groove wall. After rebounding, the hook surface of the high end 3211 forms an inverted buckle with the connecting groove. The greater the pulling force generated when the drawer is under load, the closer the inverted buckle fits, and the first elastic hook 321 will not withdraw on its own, achieving a self-locking effect where the greater the force, the more secure the lock. During assembly, the assembler only needs to push it in once along the length of the side panel to complete the engagement of the first elastic hook 321 with the first connecting groove 16, without the need for screws, rivets, or additional tooling. When the second connecting part 3 needs to be repaired or replaced, simply use a thin wrench or similar tool to gently press the high end 3211 from the groove opening to make it press down again to remove it from the first connecting groove 16, achieving non-destructive disassembly, high maintenance efficiency, and without damaging the surface of the double-layer board.

[0048] To facilitate the smooth entry of the second connecting part 32 into the mounting chamber 14, a first guide slope is provided at the end of the second connecting part 32 near the side plate body 1. The first guide slope facilitates the entry of the second connecting part 32 into the mounting chamber 14. The vertical distance between the end of the first guide slope near the side plate body 1 and the center line of the mounting chamber 14 is less than the vertical distance between the end of the first guide slope away from the side plate body 1 and the center line of the mounting chamber 14. The first guide slope changes the initial stage of assembly from surface contact to line contact, greatly reducing frictional resistance. Workers or robots can easily push the second connecting part 3 into the mounting chamber 14, reducing the sensitivity to alignment errors. At the same time, when the second connecting part 3 is assembled into the mounting chamber 14, the first guide slope automatically guides the alignment, aligning the center line of the second connecting part 3 with the center line of the mounting chamber 14. This provides an accurate reference for the subsequent engagement of the first elastic hook 321 or bolt tightening, ensuring that the overall connection strength is consistent with the design expectations.

[0049] Please see Figure 2 and Figure 8 Furthermore, to enhance the connection stability between the first plate 11 and the second plate 12 and the second connector 3, multiple protrusions 17 are provided on the end faces of the first plate 11 and the second plate 12 facing the second connector 3. The second connector 3 is provided with a flange 33 along its length, and multiple second connecting grooves 331 are provided on the flange 33 corresponding to the protrusions 17. The protrusions 17 and the second connecting grooves 331 are arranged in a one-to-one correspondence. When the second connector 3 is installed on the side plate body 1, the protrusions 17 are engaged in the second connecting grooves 331. The protrusions 17 and the second connecting grooves 331 are rigidly fitted. Multiple protrusions 17 and second connecting grooves 331 are interlocked at multiple points to form a series of micro tenons and mortises. When the drawer is subjected to lateral impact or eccentric load, the torque is distributed to each protrusion 17 and the mating point of the second connecting groove 331, significantly suppressing the torsion of the high side plate and the slippage of the second connector 3. Even if one protrusion 17 is chipped due to overload, the remaining protrusions 17 can still continue to bear the load, and the connection will not fail instantly, providing a safety redundancy for the heavy-load conditions of the high drawer.

[0050] It is worth mentioning that the first connector 2 and the second connector 3 are engaged with the side plate body 1 at one end by a snap-fit ​​and locked with bolts at the other end. During assembly, the first connector 2 and the second connector 3 can be pushed in respectively. For later maintenance, the bolts can be unlocked to release the constraint at one end of the first connector 2 and the second connector 3. The first connector 2 and the second connector 3 can be pulled out by hand for replacement, reducing after-sales labor time.

[0051] Please see Figure 9 and Figure 10The high side panel also includes a fixing member 4, which is disposed on the side of the first connecting member 2 away from the second connecting member 3. The fixing member 4 is used to enhance the installation stability of the first plate 11 and the second plate 12 away from the mounting bracket 13. The fixing member 4 has a limiting groove 41 on the end face facing the first bent portion 111 and the second bent portion 121. The fixing member 4 is disposed in the mounting chamber 14, and the first bent portion 111 and the second bent portion 121 are located in the limiting groove 41 to fix the first plate 11 and the second plate 12. In this embodiment, the limiting groove 41 is an "L" shaped groove. The fixing member 4 is pushed into the mounting chamber 14 from the end near the panel. The first bent portion 111 and the second bent portion 121 enter the limiting groove 41 from one side. The first bent portion 111 and the second bent portion 121 abut against the groove wall of the "L" shaped groove to limit the movement in the thickness direction of the side panel body 1, thereby fixing the first plate and the second plate.

[0052] Furthermore, to facilitate the installation of the fastener 4 within the mounting chamber 14, the fastener 4 has a plug-in portion 42 on the side near the first connector 2. The plug-in portion 42 has a second guide slope 421322, which facilitates the fastener 4's entry into the mounting chamber 14. The vertical distance between the end of the second guide slope 421322 near the side plate body 1 and the centerline of the mounting chamber 14 is less than the vertical distance between the end of the second guide slope 421322 away from the side plate body 1 and the centerline of the mounting chamber 14. When the fastener 4 is assembled into the mounting chamber 14, it is automatically guided by the sliding of the second guide slope 421322, aligning the centerline of the fastener 4 with the centerline of the mounting chamber 14, ensuring that the first bent portion 111 and the second bent portion 121 are accurately inserted into the limiting groove 41.

[0053] Please see Figure 11 To prevent the fastener 4 from sliding out of the mounting chamber 14 and to enhance its installation stability, the insertion part 42 is provided with a second elastic hook 422, and the first connecting member 2 is provided with a relief groove 24 that cooperates with the second elastic hook. When the fastener 4 is installed in the mounting chamber 14, the second elastic hook is located in the relief groove 24, so that the fastener 4 and the first connecting member 2 are relatively fixed. It can be understood that if the fastener 4 is inserted into the mounting chamber 14 and no "click" sound is heard from the second elastic hook, it means that it is not fully in place. The worker can immediately sense this and push it in again. Once the second elastic hook springs into the relief groove 24, it gives a signal that it is in place, avoiding over-insertion that could damage the chamber or under-insertion that could cause misalignment. After the fastener 4 is pushed in place, the second elastic hook springs back into the relief groove 24 to form an inverted limit, so that the fastener 4 and the first connecting member 2 are relatively fixed. Even if the drawer is subjected to vibration or impact for a long time, the fastener 4 will not slide out along the axial direction of the chamber.
