Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a backrest honeycomb panel mounting structure. Background Technology

[0002] In the design and manufacturing of car seats, rear seats need to provide a bed-like resting space when folded down. Therefore, most rear seat backrests have added support structures. The most common support structure is a metal sheet metal part. However, due to the weight and high surface hardness of metal sheet metal, it cannot meet the requirements of lightweighting and passenger comfort. Therefore, PP honeycomb panels are used to replace sheet metal parts. However, the PP honeycomb panels cannot be welded to the seat frame, so a new PP honeycomb panel installation structure needs to be designed. Traditional installation methods mostly fix the honeycomb panels to the seat back frame with clips. One method is to set multiple brackets on the back frame, and the honeycomb panels are fixed to the clips in the brackets using Christmas tree clips; another method is to directly set the clip structure on the back frame, and the honeycomb panels are also fixed to the clip structure using Christmas tree clips. These traditional installation structures have significant problems: 1. Setting multiple brackets or directly creating a large number of clip structures on the frame undoubtedly increases the complexity of the installation structure. Multiple brackets mean more parts are needed, resulting in higher part costs. 2. The operation is cumbersome. Using Christmas tree clips for fixing requires the operator to accurately align the clips with the holes and insert them forcefully. This process is not only time-consuming, but also prone to problems such as the clips not being able to be inserted smoothly or becoming loose after insertion, requiring repeated adjustments, resulting in high labor costs. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a backrest honeycomb panel installation structure to reduce material costs and improve assembly efficiency.

[0004] To achieve the above objectives, this utility model proposes a backrest honeycomb panel installation structure, including a backrest frame and a honeycomb panel disposed on the back of the backrest frame. The backrest frame includes a main frame and supporting steel wires welded to the main frame. The supporting steel wires are arched backward to fit the honeycomb panel. The honeycomb panel is fixed to the supporting steel wires by a number of C-shaped nails. The supporting steel wires are also provided with Y-direction positioning protrusions and Z-direction positioning protrusions. Limiting grooves are respectively formed on the honeycomb panel at the corresponding Y-direction positioning protrusions and Z-direction positioning protrusions. The Y-direction positioning protrusions and Z-direction positioning protrusions are respectively engaged in the corresponding limiting grooves to achieve Y-direction and Z-direction limiting of the honeycomb panel, thereby working together with the C-shaped nails to achieve a fixed connection between the honeycomb panel and the backrest frame.

[0005] In the above scheme: the supporting steel wires include a grid-shaped supporting steel wire welded inside the main frame and side wing supporting steel wires welded to the outer ends of the main frame. The grid-shaped supporting steel wires are composed of two Y-axis steel wires and two Z-axis steel wires spaced apart. The left and right ends of the honeycomb panel are respectively fixed to the two Z-axis steel wires by several C-shaped nails. Using the two Z-axis steel wires for C-shaped nail fixation results in a simple structure and convenient operation.

[0006] In the above scheme: the Y-direction positioning protrusion is arranged on the side wing support wire, and the Z-direction positioning protrusion is arranged on the Y-direction wire located relatively lower. Positioning the honeycomb panel from two key directions greatly improves the installation accuracy and stability of the honeycomb panel.

[0007] In the above scheme: the Y-direction positioning protrusion is formed by locally bending the side wing support steel wire obliquely backward, and the Z-direction positioning protrusion is formed by locally bending the corresponding Y-direction steel wire backward. The structure is simple and easy to process.

[0008] In the above scheme: the C-shaped nails are driven in from the back of the honeycomb panel, and three C-shaped nails are attached to each of the two Z-direction steel wires, with the three C-shaped nails distributed vertically at intervals. Attaching three C-shaped nails to each of the two Z-direction steel wires significantly increases the firmness between the honeycomb panel and the Z-direction steel wires compared to single-point or a few fixing points.

[0009] In the above scheme, installation positioning holes are opened at the pre-installation positions of each C-shaped nail on the honeycomb board, which makes it convenient for installers to quickly and accurately find the installation position of the C-shaped nail.

[0010] In the above scheme: the two ends of the main frame are also welded with support steel wires for embedding in the backrest foam, which can provide basic structural support for the backrest foam and prevent the foam material from deforming excessively when subjected to force.

[0011] The beneficial effects of this utility model are:

[0012] 1. The supporting steel wire arches backward to fit snugly against the honeycomb panel. This design ensures a tight fit between the honeycomb panel and the backrest frame, reducing gaps and facilitating fixation with C-shaped nails. 2. The honeycomb panel and backrest frame are fixedly connected using only the supporting steel wire, C-shaped nails, and the combination of positioning protrusions and limiting grooves. The supporting steel wire is the original wire on the backrest, with only minor adjustments. This design effectively reduces the number of parts, avoiding the cumbersome bracket layout or numerous locking holes in traditional structures. This makes the entire honeycomb panel installation structure simpler and more compact, saving manpower, resources, and time. 3. The combination of the Y-positioning protrusion, Z-positioning protrusion, and corresponding limiting grooves ensures precise positioning of the honeycomb panel during installation and prevents Y and Z-axis misalignment, ensuring installation stability.

[0015] Figure 3 This is a schematic diagram of the installation of the backrest frame and the backrest foam. Detailed Implementation

[0016] like Figure 1 As shown in Figure 3, a backrest honeycomb panel installation structure mainly consists of a backrest frame and a honeycomb panel 1 disposed on the back of the backrest frame.

[0017] The backrest frame includes a main frame 2 and a support wire 3 welded to the main frame 2. The support wire 3 arches backward to fit the honeycomb panel 1. The honeycomb panel 1 is fixed to the support wire 3 by several C-shaped nails.

[0018] The supporting steel wire 3 is also provided with a Y-direction positioning protrusion 4 and a Z-direction positioning protrusion 5. The honeycomb panel 1 is provided with limiting grooves 11 at the corresponding Y-direction positioning protrusion 4 and Z-direction positioning protrusion 5. The Y-direction positioning protrusion 4 and Z-direction positioning protrusion 5 are respectively inserted into the corresponding limiting grooves 11 to achieve Y-direction and Z-direction limiting of the honeycomb panel 1, and then work together with the C-shaped nail to achieve fixed connection between the honeycomb panel 1 and the backrest frame.

[0019] The Y-axis refers to the left and right sides of the seat back, and the Z-axis refers to the top and bottom sides of the seat back.

[0020] This structure is often used in two rear seats arranged side by side, and the inner end of the main frame 2 is usually adjacent to the main frame 2 of the other backrest.

[0021] Ideally, the supporting steel wires 3 include a grid-shaped supporting steel wire 31 welded inside the main frame 2 and side wing supporting steel wires 32 welded to the outer ends of the main frame 2. The grid-shaped supporting steel wires 31 are composed of two Y-direction steel wires 311 and two Z-direction steel wires 312 spaced apart. The left and right ends of the honeycomb panel 1 are respectively fixed to the two Z-direction steel wires 312 by several C-shaped nails. The C-shaped nails are fixed by the two Z-direction steel wires 312, which is simple in structure and convenient in operation.

[0022] Ideally, the Y-direction positioning protrusion 4 is positioned on the side wing support wire 32, and the Z-direction positioning protrusion 5 is positioned on the relatively lower Y-direction wire 311. Positioning the honeycomb panel 1 from two key directions greatly improves the installation accuracy and stability of the honeycomb panel 1.

[0023] Ideally, the Y-direction positioning protrusion 4 is formed by partially bending the side wing support wire 32 obliquely backward, and the Z-direction positioning protrusion 5 is formed by partially bending the corresponding Y-direction wire 311 backward. This structure is simple and easy to process.

[0024] Ideally, the C-shaped nails are driven in from the back of the honeycomb panel 1, and three C-shaped nails are attached to each of the two Z-direction steel wires 312, with the three C-shaped nails distributed vertically at intervals. Attaching three C-shaped nails to each of the two Z-direction steel wires 312 significantly increases the strength between the honeycomb panel 1 and the Z-direction steel wires 312 compared to single-point or a few fixing points.

[0025] Ideally, mounting positioning holes 6 should be provided on the honeycomb panel 1 at the pre-installed positions of each C-shaped nail, so that installers can quickly and accurately find the installation positions of the C-shaped nails.

[0026] Ideally, the two ends of the main frame 2 are also welded with support steel wires 8 for embedding in the backrest foam 7, which can provide basic structural support for the backrest foam 7 and prevent the foam material from deforming excessively when subjected to force.
