Description

Technical Field

[0001] This utility model relates to the field of seating, and in particular to an inner panel mounting structure and a chair. Background Technology

[0002] In current chair manufacturing processes, the installation of the inner panel of the chair body generally adopts traditional screw fixing or a raised mounting position design. In order to achieve a stable connection between the inner panel and the chair body, existing technology requires pre-drilling screw holes on the surface of the chair body or processing a raised mounting structure on the outside of the chair body, and then locking the inner panel to the chair body with screws; if the inner panel needs to be used with a fabric cover, holes also need to be pre-drilled at the corresponding positions of the fabric cover to avoid screws or mounting positions and ensure proper assembly of the inner panel. This traditional installation structure has several drawbacks: First, it severely compromises the aesthetic integrity of the chair. Screw holes, protruding mounting points, and openings in the fabric cover disrupt the overall flatness and appearance of the chair, especially for exposed chairs or products that emphasize aesthetics. These structural marks directly reduce the product's visual competitiveness. Furthermore, the openings in the fabric cover are prone to fraying and tearing due to daily stress and friction, shortening the cover's lifespan and increasing maintenance costs for users. Second, it is inefficient and cumbersome to assemble, requiring specialized tools such as screwdrivers for screw fastening. This makes it difficult to meet modern installation requirements. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an inner panel mounting structure that enables quick assembly of the chair body inner panel and the chair body base plate.

[0004] This utility model also proposes a chair having the above-mentioned inner panel mounting structure.

[0005] On one hand, the inner plate mounting structure according to an embodiment of the present utility model includes: The base plate is equipped with clips; The inner plate is provided with a socket corresponding to the buckle. The socket includes an insertion part and a mounting part, which are connected. The buckle can pass through the insertion part and slide to the mounting part, so that the buckle and the mounting part are engaged.

[0006] According to some embodiments of the present invention, the base plate includes a first backrest with a buckle, and the inner plate includes a second backrest with an insertion hole.

[0007] According to some embodiments of the present invention, in the second backrest socket, the mounting portion is located above the insertion portion.

[0008] According to some embodiments of the present invention, in the second backrest, there are multiple buckles and insertion holes, and they are arranged in a one-to-one correspondence. The base plate also includes a first seat cushion, which is equipped with a buckle; The inner panel includes a second seat cushion portion, which has insertion holes.

[0009] According to some embodiments of the present invention, in the insertion hole of the second seat cushion, the mounting part is located on the side away from the second backrest, and the insertion part is located on the side close to the second backrest.

[0010] According to some embodiments of the present invention, a guide surface is provided between the insertion part and the mounting part, and the buckle slides along the guide surface so that the buckle can slide from the insertion part to the mounting part.

[0011] According to some embodiments of the present invention, a spring is also included, which is disposed in the insertion portion and connected to the side of the insertion portion away from the mounting portion.

[0012] According to some embodiments of the present invention, the buckle sequentially includes a fixing part, a connecting part, and a snap-fit ​​part. The fixing part is mounted on the base plate, and the width of the connecting part is smaller than the width of the snap-fit ​​part.

[0013] According to some embodiments of the present invention, a locking member is also included, which is used to fix the buckle on the base plate.

[0014] On the other hand, the chair according to the present invention includes the inner panel mounting structure according to the above embodiments of the present invention.

[0015] The embodiments of this utility model have at least the following beneficial effects: The inner panel structure is relatively thin and deformable. The buckle assembly is installed on the base plate of the chair body. Simply position the buckle on the base plate, and the inner panel snaps onto the buckle fixed to the chair body from top to bottom. The opening of the insertion part of the inner panel is larger than that of the buckle, increasing the tolerance for error. After the buckle enters the insertion part, it slides towards the mounting part, so that the mounting part and the buckle engage and lock in place. In terms of assembly efficiency, this structure achieves "tool-free quick assembly". The operation only requires two steps: "positioning and snapping - sliding engagement", which can be completed by a single person. Compared with the traditional screw fixing method, it reduces labor costs, improves assembly efficiency, and eliminates the need for repeated alignment of holes, greatly reducing operational errors.

[0016] Meanwhile, the structural design takes into account both high fault tolerance and long-term stability: the opening of the inner plate insertion hole is larger than the buckle size, which can accommodate the slight installation deviation of the base plate buckle and the tolerance of mass-produced parts, avoiding assembly jamming; the buckle and the mounting part adopt a mechanical interlocking design, so that the buckle can be fixedly installed in the mounting part.

[0028] Reference Figures 1-7 The basic embodiment of the first aspect of this utility model provides an inner plate mounting structure, including: The base plate is 100mm and has a buckle 110. The inner panel 200 is provided with a socket 210 corresponding to the buckle 110. The socket 210 includes an insertion part 211 and a mounting part 212. The insertion part 211 and the mounting part 212 are connected. The buckle 110 can pass through the insertion part 211 and slide to the mounting part 212, so that the buckle 110 and the mounting part 212 are engaged.

[0029] According to the embodiments of this utility model, by setting it up in this way, at least the following effects can be achieved: the inner panel 200 has a thin structure and can deform; the buckle 110 is assembled on the chair body and installed on the base plate 100; once the position of the buckle 110 on the base plate 100 is determined, the inner panel 200 is fastened to the buckle 110 on the chair body from top to bottom; the opening of the insertion part 211 of the inner panel 200 is larger than that of the buckle 110, increasing the tolerance for error; after the buckle 110 enters the insertion part 211, the buckle 110 slides towards the mounting part 212, so that the mounting part 212 and the buckle 110 engage and cooperate, and the buckle 110 is fixed on the insertion hole 210. In terms of assembly efficiency, this structure achieves "tool-free quick assembly", and the operation only requires two steps: "positioning and fastening - sliding engagement", which can be completed by a single person. Compared with the traditional screw fixing method, the labor cost is reduced, the assembly efficiency is improved, and there is no need to repeatedly align the hole positions, which greatly reduces the operation error.

[0030] Meanwhile, the structural design takes into account both high fault tolerance and long-term stability: the width of the insertion part 211 is greater than the size of the buckle 110, which can accommodate the slight installation deviation of the base plate 100 buckle 110 and the tolerance of mass-produced parts, avoiding assembly jamming; the buckle 110 and the mounting part 212 adopt a mechanical interlocking design, so that the buckle 110 can be fixedly installed on the mounting part 212.

[0031] In some embodiments, multiple buckles 110 and sockets 210 are provided and are arranged in a one-to-one correspondence. By cooperating with multiple sets of buckles 110 and sockets 210, the force on each area of ​​the inner panel 200 is more balanced, which can not only avoid problems such as deformation and cracking of the inner panel 200 due to localized force concentration, but also further improve the overall firmness of the connection between the two.

[0032] In some embodiments, the base plate 100 includes a first backrest and / or a first seat cushion, and the inner plate 200 includes a second backrest and / or a second seat cushion. Multiple buckles 110 are respectively disposed on the first backrest and the first seat cushion, and multiple insertion holes 210 are respectively disposed on the second backrest and the second seat cushion. The base plate 100 and the inner plate 200 may only have a backrest or a seat cushion, or both. The backrest and seat cushion of the base plate 100 and the inner plate 200 can be integrally molded, simplifying the processing and molding of parts and facilitating subsequent assembly. Simultaneously, the buckles 110 and insertion holes 210 respectively fix the backrest and seat cushion areas, achieving precise alignment and fixation between different functional areas of the inner plate 200 and the base plate 100, avoiding overall loosening caused by fixing a single area, and making the connection between the inner plate 200 and the base plate 100 more targeted and reliable.

[0033] In some embodiments, in the insertion hole 210 of the second backrest, the mounting portion 212 is located above the insertion portion 211. In the insertion hole 210 of the backrest, the mounting portion 212 is located on the side away from the seat cushion, and the insertion portion 211 is close to the seat cushion. During installation, the buckle 110 slides upward through the insertion portion 211 and engages with the mounting portion 212. When the chair is in use, the inner panel 200 backrest mainly bears the downward force and is hardly subjected to the upward force of separation. From the perspective of force distribution logic, the possibility of the backrest inner panel 200 detaching from the base plate 100 is eliminated.

[0034] In some embodiments, in the insertion hole 210 of the second seat cushion, the mounting portion 212 is located on the side away from the second backrest, and the insertion portion 211 is located on the side close to the second backrest. For the seat cushion, during installation, the buckle 110 first passes through the insertion portion 211 and then moves backward, so that the buckle 110 engages with the mounting portion 212. In use, the inner panel 200 is generally subjected to a downward force and is unlikely to be subjected to a forward or backward force, thus making it difficult for the seat cushion to detach from the base plate 100. Furthermore, combined with the above-mentioned "in the insertion hole 210 of the second backrest, the mounting portion 212 is located above the insertion portion 211," the mounting portions 212 of the insertion holes 210 on both the backrest and the seat cushion are located far apart from each other, while the insertion portions 211 of the insertion holes 210 on both the backrest and the seat cushion are located close together. This arrangement allows the forces on the backrest and the seat cushion to be balanced and complementary, avoiding localized force concentration that could damage the overall connection structure, and further improving the long-term stability of the entire installation structure.

[0035] In some embodiments, a guide surface 213 is provided between the insertion part 211 and the mounting part 212. The latch 110 slides along the guide surface 213 so that the latch 110 can slide from the insertion part 211 to the mounting part 212. The guide surface 213 plays a guiding role. The guide surface 213 is generally set as a sloped structure or an arc surface structure. When the latch 110 enters the insertion part 211, it can slide smoothly along the guide surface 213 to the mounting part 212 without deliberately adjusting the angle. This greatly reduces the frictional resistance during the sliding process, effectively avoids the latch 110 from getting stuck, makes the assembly operation more labor-saving and the process smoother, and further improves the assembly efficiency.

[0036] In some embodiments, a spring 300 is also included, which is disposed within the insertion portion 211 and connected to the side of the insertion portion 211 away from the mounting portion 212. The spring 300 has excellent elastic properties; when the latch 110 is inserted into the insertion portion 211, the spring 300 will elastically deform accordingly, without hindering the insertion action of the latch 110, thus ensuring that the assembly process is not affected. After the latch 110 slides to the mounting part 212 and completes the engagement, the spring 300 will return to its original state. On the one hand, it can reliably limit the latch 110. When the latch 110 tends to slide towards the insertion part 211, the spring 300 will tightly abut against the latch 110, effectively preventing the latch 110 from detaching from the mounting part 212 and strengthening the anti-detachment performance of the connection. On the other hand, the spring 300 can cover the socket 210 of the inner panel 200, preventing the user from directly contacting the gap of the socket 210 when touching the inner panel 200, which not only improves the touch feel, but also makes the appearance of the inner panel 200 neater and more uniform.

[0037] In some embodiments, the buckle 110 is circular, elliptical, or polygonal. The buckle 110 employs various shapes such as circular, elliptical, polygonal, or irregular shapes, greatly enhancing the structural adaptability. This design is not limited to a single shape and can be flexibly adjusted according to the overall shape of the inner panel 200 and the base plate 100, stress requirements, and manufacturing processes. It is not restricted to a fixed form and can adapt to the production needs of chairs of different styles and structures, enhancing the versatility and applicability of this installation structure.

[0038] In some embodiments, the snap fastener 110 sequentially includes a fixing part 111, a connecting part 112, and a snap-fit ​​part 113. The fixing part 111 is mounted on the base plate 100, and the width of the connecting part 112 is smaller than the width of the snap-fit ​​part 113. This further enhances the secureness of the snap-fit. The fixing part 111 ensures that the snap fastener 110 is stably mounted on the base plate 100, preventing the snap fastener 110 from loosening itself. The narrower connecting part 112, combined with the wider snap-fit ​​part 113, allows the snap-fit ​​part 113 to form a tight limiting engagement with the mounting part 212 of the insertion hole 210, making it difficult for displacement to occur after snap-fit. This effectively improves the snap-fit ​​strength between the snap fastener 110 and the insertion hole 210, ensuring the stability of the connection between the inner plate 200 and the base plate 100.

[0039] In some embodiments, a locking element 400 is also included, which is used to securely mount the buckle 110 onto the base plate 100. The locking element 400 can be a nail gun or glue. The locking element 400 can be flexibly selected according to the material of the base plate 100, the production scenario, and the stress requirements: nail guns are suitable for easy-to-fix materials such as plastic and wood, and are efficient in assembly; glue is suitable for base plates 100 that are not suitable for drilling, so as to avoid damaging the structure of the base plate 100; screws are suitable for scenarios with higher connection strength requirements, and can achieve detachable fixing, which is convenient for later maintenance and adjustment. The adaptability design of various locking elements 400 allows this installation structure to adapt to different production needs, while ensuring that the connection between the buckle 110 and the base plate 100 is firm, thus ensuring the overall stability of the inner plate 200 installation from the source. The locking component 400 is made of nail gun and glue, which can prevent damage to the structure of the base plate 100 during production. One base plate 100 can be made in multiple configurations, such as a single chair body or a chair body plus an inner panel. Only one set of molds is needed to complete the production, saving production costs. Moreover, there is no need to distinguish between different configurations of the base plate 100 for production material preparation, which improves production efficiency.

[0040] In some embodiments, the inner panel 100 is provided with a through hole 120, which can reduce the area of ​​the connection structure between the second backrest and the second seat cushion on the inner panel, and is beneficial for the bending of the inner panel.
