A buckle mounting structure of a backrest panel

Abstract

This application relates to a snap-fit ​​installation structure for a backrest panel, including a panel body and multiple snap-fit ​​components. The panel body has several slots, and the bottom surfaces of these slots each have snap-fit ​​grooves facing both sides. Each snap-fit ​​component corresponds to one of the slots, and each snap-fit ​​component has two elastic snap-fit ​​members. The elastic snap-fit ​​members are L-shaped, with one end fixedly connected to a snap-fit ​​member and the other end engaging with the corresponding snap-fit ​​groove. By designing the snap-fit ​​structure as independent snap-fit ​​components, a detachable connection is achieved between the snap-fit ​​member and the panel body through slots, snap-fit ​​grooves, and elastic snap-fit ​​members. If a snap-fit ​​member is damaged during disassembly or assembly, only the snap-fit ​​member needs to be replaced, eliminating the need to scrap the entire backrest panel, significantly reducing panel loss and production costs.

Description

Technical Field

[0001] This utility model relates to the field of panel mounting structures, and in particular to a snap-fit ​​mounting structure for a backrest panel. Background Technology

[0002] like Figure 8 The image shows a backrest panel in the prior art, which is installed by a snap-fit ​​structure. However, the snap-fit ​​structure is usually integrally formed with the backrest panel. During the disassembly and assembly process, improper operation often causes the snap-fit ​​on the backrest panel to break or be snapped, resulting in the scrapping of the backrest panel. This leads to a high loss rate of backrest panels during product assembly or recycling, which increases production costs. Utility Model Content

[0003] To reduce the possibility of the snap-fit ​​structure breaking during disassembly and assembly, this application provides a snap-fit ​​mounting structure for a backrest panel.

[0004] The snap-fit ​​mounting structure for a backrest panel provided in this application adopts the following technical solution: A snap-fit ​​mounting structure for a backrest panel includes a panel body and multiple snap-fit ​​components. The panel body has several slots, and the bottom surfaces of the slots have snap-fit ​​grooves facing both sides. The snap-fit ​​components correspond to the slots, and each snap-fit ​​component has two elastic snap-fit ​​components. The elastic snap-fit ​​components are L-shaped, with one end fixedly connected to the snap-fit ​​component and the other end engaging with the corresponding snap-fit ​​groove.

[0005] By adopting the above technical solution, the buckle structure is designed as an independent buckle component, which is detachably connected to the panel body through slots, locking grooves, and elastic locking components, rather than being integrally formed with the panel. The buckle component is an independent part, and if it is damaged during disassembly or assembly, only the buckle component needs to be replaced, without scrapping the entire back panel, which greatly reduces the panel loss rate and production costs. At the same time, the elastic locking design of the independent buckle component retains the convenience of quick disassembly and assembly, taking into account both assembly efficiency and maintenance economy.

[0006] Preferably, the end of the elastic snap-fit ​​member away from the buckle member is provided with a guide protrusion, which is formed by bending the end of the elastic snap-fit ​​member away from the buckle member.

[0007] By adopting the above technical solution, the guide protrusion can guide the elastic snap-fit ​​component to smoothly insert into the snap-fit ​​slot, reducing the operating resistance and alignment difficulty during disassembly and assembly, reducing the risk of damage to the snap-fit ​​component or the main body of the panel due to improper operation, and further reducing the probability of scrap.

[0008] Preferably, the end of the elastic snap fastener used for guiding the protrusion is provided with a plastic-coated part, the plastic-coated part is formed by bending the end of the elastic snap fastener away from the buckle, and the buckle is wrapped on the plastic-coated part by the plastic-coating process.

[0009] By adopting the above technical solutions, the plastic coating can strengthen the connection between the elastic snap fastener and the snap fastener, preventing them from separating or breaking when subjected to stress during disassembly and assembly, improving the durability of the snap fastener, and reducing the frequency of replacement due to damage to the snap fastener itself.

[0010] Preferably, the snap-fit ​​groove is tapered from the side closest to the corresponding slot to the side furthest from the corresponding slot.

[0011] By adopting the above technical solution, the tapered locking groove gradually compresses the elastic locking component after insertion, forming a tighter fit as it is inserted, reducing the probability of loosening between the locking component and the panel body; at the same time, the force is more even during disassembly, avoiding the problem of traditional integrated locking that is easy to fall off due to being too loose, or breakage due to being too tight when forcibly disassembled, thus reducing the risk of damage from improper operation.

[0012] Preferably, the fastener has several ribs, and the panel body has several mating grooves that can cooperate with it. When the fastener is installed on the panel body, the several ribs cooperate with the mating grooves.

[0013] By adopting the above technical solution, the cooperation between the rib plate and the mating groove can help position the fastener, avoiding the breakage of the elastic fastener due to uneven force caused by the offset of the fastener during disassembly and assembly; at the same time, it increases the contact area between the fastener and the panel body, disperses the force, reduces local stress concentration, and reduces the possibility of damage to the panel or fastener due to excessive force at a single point.

[0014] Preferably, it also includes a plurality of reinforcing ribs, which are fixedly connected to the fasteners and their two ends are respectively fixedly connected to adjacent ribs.

[0015] By adopting the above technical solutions, the reinforcing ribs can improve the overall structural strength and rigidity of the fasteners, prevent the fasteners from deforming during disassembly and assembly, extend the service life of the fasteners, reduce the need for panel installation instability or replacement due to fastener deformation and failure, and indirectly reduce costs.

[0016] Preferably, the buckle is arranged in a gradually expanding shape from the end away from the elastic snap-fit ​​member to the end closer to the elastic snap-fit ​​member.

[0017] By adopting the above technical solution, the gradually expanding design makes it easier to align the buckle when it is inserted into the slot, reducing the resistance during insertion and the risk of deformation or breakage caused by forceful pressing; at the same time, the gradually expanding structure can form a tighter fit with the inner wall of the slot after installation, distributing the force and avoiding the problem of local breakage caused by the insertion and removal angle deviation of traditional one-piece buckles, thus improving the safety of disassembly and assembly.

[0018] The main technical effects of this utility model are reflected in the following aspects: 1. This utility model designs the buckle structure as an independent buckle component, which is detachably connected to the panel body through slots, locking grooves, and elastic locking components, rather than being integrally formed with the panel. The buckle component is an independent part, so if the buckle component is damaged during disassembly or assembly, only the buckle component needs to be replaced, without scrapping the entire back panel, which greatly reduces the panel loss rate and production costs. At the same time, the elastic locking design of the independent buckle component retains the convenience of quick disassembly and assembly, taking into account both assembly efficiency and maintenance economy. 2. The plastic coating of this utility model can strengthen the connection strength between the elastic snap fastener and the snap fastener, prevent the two from separating or breaking when subjected to force during disassembly and assembly, improve the durability of the snap fastener, and reduce the frequency of replacement due to damage to the snap fastener itself. 3. The tapered snap-fit ​​groove of this utility model causes the elastic snap-fit ​​to be gradually squeezed after insertion, forming a tighter fit as it is inserted, reducing the probability of the snap-fit ​​and the panel body becoming loose; at the same time, the force is more even during disassembly, avoiding the problem of traditional one-piece snap-fit ​​being easy to fall off due to being too loose, or breaking due to being too tight when forcibly disassembled, thus reducing the risk of damage from improper operation.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0029] This application discloses a snap-fit ​​mounting structure for a backrest panel.

[0030] Reference Figure 1 and Figure 6 This embodiment of a backrest panel buckle installation structure includes a panel body 1 and multiple buckle members 2. The panel body 1 has a plurality of slots 3. The bottom surfaces of the plurality of slots 3 are respectively provided with snap-fit ​​grooves 4 facing both sides. The plurality of buckle members 2 are respectively provided with the plurality of slots 3. The plurality of buckle members 2 are respectively provided with two elastic snap-fit ​​members 5. The elastic snap-fit ​​members 5 are arranged in an "L" shape. One end of the elastic snap-fit ​​member 5 is fixedly connected to the buckle member 2, and the other end can be snapped into the corresponding snap-fit ​​groove 4. When the elastic snap-fit ​​member 5 is installed on the panel body 1, the end of the elastic snap-fit ​​member 5 away from the buckle member 2 first snaps into the snap-fit ​​groove 4, and the other end is inserted into the slot 3.

[0031] Reference Figure 5 Each of the two elastic snap fasteners 5 has a guide protrusion 6 at the end furthest from the snap fastener 2. The guide protrusion 6 is formed by bending the end of the elastic snap fastener 5 furthest from the snap fastener 2. The end of the elastic snap fastener 5 used for the guide protrusion 6 has a plastic-coated part 7. The plastic-coated part 7 is formed by bending the end of the elastic snap fastener 5 furthest from the snap fastener 2. The snap fastener 2 is wrapped on the plastic-coated part 7 by the plastic-coating process.

[0032] Reference Figure 5 The guide protrusion 6 guides the elastic snap-fit ​​5 to smoothly insert into the snap-fit ​​slot 4, reducing operational resistance and alignment difficulty during disassembly and assembly, lowering the risk of damage to the snap-fit ​​2 or the panel body 1 due to improper operation, and further reducing the probability of scrap. The plastic coating 7 strengthens the connection between the elastic snap-fit ​​5 and the snap-fit ​​2, preventing them from separating or breaking under stress during disassembly and assembly, improving the durability of the snap-fit ​​2, and reducing the frequency of replacement due to damage to the snap-fit ​​2 itself.

[0033] Reference Figure 7 The snap-fit ​​groove 4 is tapered from the side closest to the corresponding slot 3 to the side furthest from the corresponding slot 3. The tapered snap-fit ​​groove 4 causes the elastic snap-fit ​​piece 5 to be gradually squeezed after insertion, forming a tighter fit as it is inserted, reducing the probability of the snap fastener 2 loosening from the panel body 1; at the same time, the force is more even during disassembly, avoiding the problem of traditional integrated snap fasteners that are easy to fall off due to being too loose or breakage due to being too tight when forcibly disassembled, thus reducing the risk of damage from improper operation.

[0034] Reference Figure 4The fastener 2 is fixedly connected to several ribs 8, which are evenly distributed along the width direction of the fastener 2. The panel body 1 has mating grooves 9 that can cooperate with the several ribs 8. The several mating grooves 9 are respectively connected to the slots 3. When the fastener 2 is installed on the panel body 1, the several ribs 8 cooperate with the mating grooves 9. It also includes several reinforcing ribs 10, which are fixedly connected to the fastener 2. The several reinforcing ribs 10 are evenly distributed along the height direction of the fastener 2, and their two ends are respectively fixedly connected to the adjacent ribs 8.

[0035] Reference Figure 4 The rib 8 and the mating groove 9 help position the fastener 2, preventing the elastic locking element 5 from breaking due to uneven stress caused by the fastener 2 shifting during disassembly and assembly. Simultaneously, it increases the contact area between the fastener 2 and the panel body 1, distributing stress, reducing local stress concentration, and lowering the possibility of damage to the panel or fastener 2 due to excessive stress at a single point. The reinforcing rib 10 improves the overall structural strength and rigidity of the fastener 2, preventing deformation during disassembly and assembly, extending its service life, reducing the need for panel installation instability or replacement due to fastener 2 deformation and failure, and indirectly reducing costs.

[0036] Reference Figure 3 The latching member 2 is gradually widened from the end furthest from the elastic latching member 5 to the end closest to the elastic latching member 5. The widening design makes it easier to align the latching member 2 when it is inserted into the slot 3, reducing the resistance during insertion and the risk of deformation or breakage caused by forceful pressing. At the same time, the widening structure can form a tighter fit with the inner wall of the slot 3 after installation, distributing the force and avoiding the problem of local breakage caused by the insertion and removal angle deviation of traditional one-piece latches, thus improving the safety of disassembly and assembly.

[0037] Reference Figure 2 The buckle structure is designed as an independent buckle component 2, which is connected to the panel body 1 through a slot 3, a snap-fit ​​groove 4, and a flexible snap-fit ​​component 5 to achieve a detachable connection, rather than being integrally formed with the panel. The buckle component 2 is an independent part. If the buckle component 2 is damaged during disassembly or assembly, only the buckle component 2 needs to be replaced, without scrapping the entire back panel, which greatly reduces the panel loss rate and production costs. At the same time, the flexible snap-fit ​​design of the independent buckle component 2 retains the convenience of quick disassembly and assembly, taking into account both assembly efficiency and maintenance economy.

[0038] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
