[0025] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] The following is combined with Figure 1-7 The utility model is described in further detail.

[0027] The utility model embodiment discloses an adjustment mechanism for solving the surface difference deformation of the charging port cover and the side enclosure.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , an adjustment mechanism for solving the face difference deformation between a charging port cover and a side enclosure, comprising a side enclosure wheel cover assembly, a side enclosure outer panel 1 and a charging port cover assembly, wherein the side enclosure wheel cover assembly is fixedly arranged on the side enclosure outer panel 1, and an adaptive face difference adjustment member 3 is arranged on the charging port cover assembly, wherein the adaptive face difference adjustment member 3 has a fitting portion sliding along the Y direction, and the charging port cover assembly is mounted on the side enclosure outer panel 1, and the adaptive face difference adjustment member 3 is manipulated to drive the fitting portion to slide to fit closely with the side enclosure wheel cover assembly, so as to absorb the manufacturing tolerance between the side enclosure wheel cover assembly and the side enclosure outer panel 1, and the Y direction tolerance accumulation caused by the influence of product design structure, component quality, welding fixture accuracy, welding deformation, etc. on the side enclosure outer panel 1 relative to the side enclosure wheel cover assembly is absorbed by the adaptive face difference adjustment member 3, thereby interrupting the original dimension chain, reducing the manufacturing accuracy of components in the relevant environment, reducing the demand for dimensional accuracy control of relevant components inside the body-in-white, saving quality control costs, reducing the rework time in the later stage of assembly, and shortening the trial production cycle.

[0029] In this embodiment, the side wheel arch assembly includes a side inner panel assembly and a D-pillar reinforcement plate 2. The middle section of the D-pillar reinforcement plate 2 is welded to the side inner panel assembly in the Y direction. The side inner panel assembly is directly welded to the side outer panel 1. The charging port cover assembly is fixed to the D-pillar reinforcement plate 2 by an adaptive surface difference adjustment part 3.

[0030] In this embodiment, the charging port cover assembly includes a charging port cover body 4 , and the charging port cover body 4 is installed in the middle section of the D-pillar reinforcement plate 2 in the Y direction through an adaptive surface difference adjustment member 3 .

[0031] An installation opening is provided on the side outer panel 1, the edge of the installation opening is recessed inward and then extends toward the center to form an annular step to form a clamping portion, and the annular step is used to limit the Y-direction displacement and Z-direction displacement of the charging port cover body 4Z. The charging port cover body 4X is clamped on the step of the side outer panel 1, forming a limit for the charging port cover body 4 along the Z-direction and Y-direction, thereby completing the Y-direction and Z-direction positioning.

[0032] There may be multiple adaptive face difference adjustment members 3. In this embodiment, there are three adaptive face difference adjustment members 3. The three adaptive face difference adjustment members 3 are distributed in a triangular shape on the charging port cover assembly. The triangular distribution can improve the stability of the charging port cover assembly installation. Specifically, the area ratio of the triangle formed by the three adaptive face difference adjustment members 3 to the area of ​​the charging port cover assembly is greater than 2 / 3 and not greater than 1. Being within this area ratio range can make the adaptive face difference adjustment member 3 fix the charging port cover assembly more firmly, further improving the stability.

[0033] In this embodiment, the adaptive face difference adjustment member 3 includes an adaptive head 31, a fixed head 32 and a bolt 33. The fixed head 32 is fixedly arranged on the charging port cover body 4. The adaptive head 31 can automatically adjust the internal torque and pitch according to the size and shape of the threaded hole to ensure matching with the threaded hole. The fixed head 32 includes a fixed head 32 body and a thread ring. The thread ring is arranged on the inner contour of the fixed head 32 body. The thread ring of the fixed head 32 is threadedly matched with the adaptive head 31. The fixed head 32 can directly use a threaded sleeve.

[0034] The adaptive head 31 has a limiting portion 35 for limiting the sliding of the head of the bolt 33 along the Y direction. The limiting portion 35 is integrally formed at the end of the adaptive head 31 close to the D-pillar reinforcement plate 2. A hole is opened at the central position of the limiting portion 35 to allow the screw portion of the bolt 33 to pass through and be threadedly connected to the side wheel cover assembly. The head of the bolt 33 can be manipulated to drive the adaptive head 31 to rotate through the friction between the two to move the adaptive head 31 along the Y direction to absorb the manufacturing tolerance between the side wheel cover assembly and the side outer panel 1. The adaptive face difference adjustment member 3 of the utility model can automatically adapt to the size and shape of the threaded hole during installation, absorb the Y-direction cumulative tolerance of the side outer panel 1 and the middle section of the D-pillar reinforcement plate 2, avoid deformation of the side outer panel 1, and effectively ensure that the gap face difference of the entire vehicle is achieved, thereby achieving a tighter joining effect.

[0035] In this embodiment, a friction plate 34 is provided between the limiting portion 35 and the screw portion of the bolt 33. In this embodiment, the friction plate 34 is a cylindrical friction plate 34. The friction coefficients at both ends of the friction plate 34 are different. When the force applied by the screw portion of the bolt 33 to the friction plate 34 is greater than the friction force of the friction plate 34 on the limiting portion 35, the screw portion of the bolt 33 can rotate relative to the adaptive head 31 through the friction plate 34 to form idling. When the bolt 33 is completely driven into the side wheel cover assembly, due to the effect of the friction plate 34, the bolt 33 cannot drive the adaptive head 31 to continue to rotate. The bolt 33 idling relative to the adaptive head 31 effectively avoids the adaptive head 31 and the bolt 33 from moving too far, ensuring the installation stability. The radial pressure between the adaptive head 31 and the fixed head 32 is controlled by the friction plate 34, which can ensure that there is a reliable contact area between the adaptive nut and the D-pillar reinforcement plate 2, thereby achieving the tightening effect.

[0036] The fixing head 32 is provided with a bracket 7, and the charging port cover body 4 is provided with a connecting frame 8, the connecting frame 8 has a mounting portion, and the bracket 7 is clamped with the mounting portion. Specifically, the longitudinal section of the connecting frame 8 is approximately M-shaped. In this embodiment, three brackets 7 are provided on the fixing head 32, which are respectively clamped with the connecting frames 8 of the corresponding charging port cover body 4. The three brackets 7 are clamped with the connecting frames 8, which can effectively absorb the accumulated X-direction and Y-direction tolerances manufactured on the white body.

[0037] The utility model absorbs the Y-direction tolerance accumulation caused by the product design structure, component quality, welding fixture accuracy, welding deformation, etc. of the side panel outer panel 1 on the body-in-white relative to the side panel wheel cover assembly, as well as the X-direction and Y-direction tolerance accumulation and the manufacturing tolerance of the components of the charging port cover assembly itself, through the adaptive surface difference adjustment part 3, so as to avoid the side panel outer panel 1 being ejected and deformed in the Y direction by the charging port cover assembly due to the manufacturing tolerance; it can effectively interrupt the original dimension chain, reduce the component manufacturing accuracy of the related environment, reduce the demand for dimensional accuracy control of related components inside the body-in-white, save quality control costs, reduce the labor hours for rework in the later stage of assembly, shorten the trial production cycle, and there is no need to disassemble the D-pillar interior panel and polish the charging port cover assembly after assembly, which effectively avoids the side panel outer panel 1 being ejected and deformed in the Y direction by the charging port cover assembly due to the manufacturing tolerance, meets the DTS surface difference of the charging port cover area of ​​the whole vehicle, and improves the customer-perceived quality.

[0038] Compared with the traditional charging port cover assembly, which has high requirements on the dimensional accuracy of the white body and a long dimensional chain link, the utility model eliminates the need to directly tighten the charging port cover assembly to the inner plate of the D-pillar on the body, and adopts an adaptive surface difference adjustment part 3, which shortens the dimensional chain and ensures that the DTS of the charging port cover area of ​​the entire vehicle is achieved, thereby improving customer-perceived quality.

[0039] In this embodiment, the X direction is the length direction of the vehicle body, the Y direction is the width direction of the vehicle body, and the Z direction is the height direction of the vehicle body.
