Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a C-pillar under-interior protective plate for automobiles. Background Technology
[0002] As an important component of automobiles, the C-pillar under-pillar interior trim panel needs to be inspected after assembly. Since the C-pillar under-pillar interior trim panel is injection molded, irreversible damage can easily be caused when fixing the edges of the C-pillar under-pillar interior trim panel before inspection. Damaged edges will adversely affect the installation and sealing performance of the C-pillar under-pillar interior trim panel. Moreover, the shape of the C-pillar under-pillar interior trim panel varies greatly from car model to car model, so tooling often needs to be changed during fixing, which is very inconvenient. Therefore, designing a C-pillar under-pillar interior trim panel to solve the above problems is particularly important. Summary of the Invention
[0003] To address the aforementioned problems, this invention designs a C-pillar under-interior trim protection plate for automobiles. Two detachable mounting brackets are provided on the C-pillar under-interior trim protection plate. These brackets allow for quick and easy fixing of the C-pillar under-interior trim protection plate during inspection. This method not only reduces damage to the C-pillar under-interior trim protection plate but also enables rapid fixing, thus increasing its practicality.
[0004] To solve the above-mentioned technical problems, this utility model provides a C-pillar under-interior trim panel for automobiles, characterized in that: it includes a C-pillar under-interior trim panel body; the right half of the outer side of the C-pillar under-interior trim panel body is provided with an elongated first buckle seat, and each end of the first buckle seat has a buckle connection hole; the left half of the outer side of the C-pillar under-interior trim panel body is provided with two square second buckle seats, and the center of the second buckle seat also has a buckle connection hole; the first and second buckle seats are fixed to the C-pillar under-interior trim panel body by bolts; the C-pillar under-interior trim panel body is installed on the vehicle frame through the buckle connection hole and the buckle engagement; the bottom of the C-pillar under-interior trim panel body is provided with a storage box support bracket for connecting the storage compartment frame; the outer side of the C-pillar under-interior trim panel body is also provided with two mounting slots, which are arranged on the left and right sides and each slot is detachably connected to a positioning mounting seat through an elastic clamping mechanism; the center of the positioning mounting seat has a threaded hole for detection and fixing.
[0005] Furthermore, the elastic clamping mechanism includes a connecting hole, a spring, and a spherical clamp on the outer wall of the positioning mounting base. The spherical clamp is connected to the connecting hole by the spring. A hemispherical groove matching the spherical clamp is provided on the inner wall of the mounting groove opposite the connecting hole. The spherical clamp is engaged in the hemispherical groove under the action of the spring.
[0006] Furthermore, the lower trim panel of the C-pillar is also provided with lower trim panel sound-absorbing cotton, and a mounting plate is fixed on the lower trim panel sound-absorbing cotton. The mounting plate is provided with a trunk lighting back panel and a third buckle seat.
[0007] Furthermore, a C-pillar lower trim panel pull wire cover back panel assembly is fixed on the C-pillar lower trim panel body below the sound-absorbing cotton of the lower trim panel. The C-pillar lower trim panel pull wire cover back panel assembly is composed of a pull wire cover and a pull wire back panel.
[0008] With the above structure, this utility model has two detachable positioning mounting seats on the C-pillar under-interior trim protection. The two positioning mounting seats can quickly fix the C-pillar under-interior trim protection panel during inspection. This method not only reduces damage to the C-pillar under-interior trim protection panel, but also allows for quick fixation, thus increasing practicality. In addition, this design has the advantages of simple structure, easy manufacturing, and convenient assembly and disassembly. Attached Figure Description
