Description

Technical Field

[0001] This utility model belongs to the field of automotive interior assembly, specifically relating to a dashboard trim panel surface difference adjuster. Background Technology

[0002] With the upgrading of automobile consumption and the explosive growth in demand for refined user experience, interior quality has become one of the core indicators for consumers' car purchase decisions. Traditional interior assembly relies on passive surface difference control methods such as shim fine-tuning and manual grinding. However, passive surface difference control methods face three major systemic bottlenecks in automotive interior assembly:

[0003] 1. Precision defects: The manual adjustment accuracy is only ±0.5mm, which easily leads to stepped surface differences at key joints such as the dashboard and door panels, ceiling and columns (measured >0.3mm can be seen by the naked eye), causing consumers to question the rough workmanship;

[0004] 2. Efficiency bottleneck: The time-consuming adjustment of interior finishes for luxury models severely restricts production line pace;

[0005] 3. Poor material adaptability: The difference in the expansion coefficient of new materials such as carbon fiber trim and microfiber leather causes dynamic surface difference drift (fluctuation amplitude ≥ 0.4mm) in temperature change environment from -40℃ to 85℃, which cannot be compensated by traditional rigid structures.

[0006] Meanwhile, innovative designs in new energy vehicles, such as panoramic sunroofs and concealed air vents, further compress interior structural space, reducing the installation tolerance of traditional adjustment mechanisms (such as roof spring clips). The industry urgently needs a surface difference adjustment technology that integrates precision mechanical control and rapid assembly. Utility Model Content

[0007] To address the aforementioned problems in the existing technology, this utility model provides an instrument panel trim surface difference adjuster. Utilizing the characteristic of displacement generated by bolt rotation, it achieves stepless adjustment of the Z-axis surface difference through physical means. The structure is simple, stable, and low-cost.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an instrument panel trim surface difference adjuster, comprising a base, bolts, an elastic support block, and an insert nut. The elastic support block is located on top of the base, and the insert nut is located above the elastic support block and embedded in the front trim panel. The bolt is inserted into the base, the elastic support block, and the nut in sequence from bottom to top. The elastic support block is located in a slot at the bottom of the front trim panel. The upper part of the base is movably engaged with the bottom of the front trim panel, and the lower part is fixedly engaged with the CCB.

[0009] Furthermore, a protrusion is provided on one side of the base, and a groove matching the protrusion is provided at the bottom of the front panel.

[0010] Furthermore, the base has two sides adjacent to the surface with the protrusion, and the fasteners are located at the lower end of the base. The CCB has an opening that matches the fastener.

[0011] Furthermore, the upper part of the bolt is threaded, and the threaded part of the bolt passes through the insert nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model utilizes the characteristic of displacement generated by bolt rotation to achieve stepless adjustment of Z-axis surface difference in the physical mechanism, with a simple and stable structure and low cost; This utility model can meet the following three needs: 1. User end: demand for a high-quality feel of "seamless" interior (a survey of luxury brands shows that surface difference complaints account for 32% of interior problems); 2. Manufacturing end: demand for cost control of automated and high-speed production (the adjustment cost per vehicle needs to be reduced to within 5 yuan); 3. After-sales service: demand for convenient maintenance (avoiding the need for complete replacement of parts due to the integrated structure). Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides the following technical solution: an instrument panel trim surface difference adjuster, including a base 1, bolts 2, elastic support blocks 3, and insert nuts 4. The elastic support blocks 3 are located on top of the base 1. The elastic support blocks 3 are elastic; they flatten when compressed and return to their original height when released. The elastic support blocks 3 are in contact with the top of the base 1. The insert nuts 4 are located above the elastic support blocks 3 and are embedded in the front trim panel 5. The bolts 2 are inserted into the base 1, elastic support blocks 3, and nuts 4 in sequence from bottom to top. The elastic support blocks 3 are located in a groove at the bottom of the front trim panel 5. The movable part is attached to the bottom of the front trim panel 5, and the lower part is fixedly attached to the CCB6. When the bolt 2 is rotated from below the CCB6 using an Allen wrench, the bolt 2 will not move. However, as the bolt 2 rotates forward and backward, the bolt 2 causes the insert nut 4 inside the front trim panel 5 to move up and down along the bolt 2. When the insert nut 4 and the front trim panel 5 move down, the front trim panel 5 compresses the elastic support block 3 in the bottom slot. When the insert nut 4 and the front trim panel 5 move up, the bottom of the front trim panel 5 releases the elastic support block 3, and the elastic support block 3 returns to a certain height, thereby realizing the stepless Z-axis adjustment of the mechanism.

[0018] Specifically, a protrusion 11 is provided on one side of the base 1, and a groove 51 adapted to the protrusion 11 is opened at the bottom of the front trim panel 5. The upper part of the base 1, except for the part with the protrusion 11, is also located in the slot at the bottom of the front trim panel 5. The protrusion 11 on the base 1 is vertical and is movable and inserted into the groove 51 of the vertical strip. When the height of the front trim panel 5 is adjusted, the groove 51 on the front trim panel 5 moves up and down along the protrusion 11. The vertical adjustment range of the front trim panel 6 is ±1.5mm.

[0019] Specifically, the base 1 has two buckles 12 on its two sides adjacent to the surface with the protrusion 11. The buckles 12 are located at the lower end of the base 1. The CCB6 has an opening 61 that matches the buckle 12. After the lower part of the base 1 passes through the opening 61, the buckles 12 on both sides of the lower end of the base 1 are locked on both sides below the opening 61, so that the upper and lower parts of the base 1 are fixed by the CCB6 and the front trim panel 5.

[0020] Specifically, the upper part of the bolt 2 is threaded and the threaded part of the bolt 2 passes through the insert nut 4. The bolt 2 is fixed when it rotates, but the insert nut 4 moves up and down under the rotation of the bolt.

[0021] The assembly and adjustment process of this utility model is as follows: First, the elastic support block 3 is installed into the slot at the bottom of the front trim panel 5. Then, the upper part of the base 1 is installed into the slot at the bottom of the front trim panel 5. At this time, the upper part of the base 1 is in contact with the lower part of the elastic support block 3, and the protrusion 11 on the base 1 is movably engaged in the groove 51. Then, the bolt 2 is inserted into the base 1, the elastic support block 3 and the nut 4 in sequence from bottom to top. Finally, the assembled front trim panel 5 assembly is assembled onto the CCB6, that is, the lower part of the base 1 passes through the opening 61, so that the two side buckles 12 are engaged on both sides below the opening 61. After the door interior panel 7 is assembled, the surface difference between the front trim panel assembly and the door interior panel 7 is measured. The bolt 2 is rotated from below the CCB6 using an Allen wrench, thereby driving the front trim panel 5 to move up and down.

[0022] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
