Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology, and in particular relates to an eccentric adjustment mechanism. Background Technology
[0002] When assembling components, it is often necessary to align two parts to ensure assembly accuracy or aesthetics after assembly. For example, to improve the appearance of a vehicle's interior, the door trim panel needs to be aligned with the dashboard. An adjustment mechanism is installed between the door trim panel and the door sheet metal to adjust the height of the door trim panel, thus aligning it with the dashboard.
[0003] Specifically, the adjustment mechanism includes a cam rotatably mounted on the door sheet metal. The door trim panel has a mating surface, and the outer circumferential surface of the cam abuts against this mating surface. By rotating the cam, different parts of the cam engage with the mating surface, thereby adjusting the height of the door trim panel and aligning it with the dashboard. However, because the relationship between the cam's rotation angle and the door trim panel's movement distance is difficult to determine, the cam can easily over-rotate. Assemblers need to rotate the cam repeatedly, resulting in a complex adjustment process and difficulty in controlling adjustment precision. Summary of the Invention
[0004] This invention provides an eccentric adjustment mechanism, which aims to solve the problems mentioned in the background art.
[0005] This utility model is implemented as follows: an eccentric adjustment mechanism, including an eccentric adjustment component;
[0006] The eccentric adjustment component includes a base and an adjustment shaft. The base is disposed on the door panel assembly whose Z-axis position needs to be adjusted. One end of the adjustment shaft is inserted into the base. A spring is provided between the base and the door panel assembly. The base is provided with multiple grooves and a marking 1.
[0007] The adjusting shaft includes a cam, two radially mating shafts and a second marking. The outer side of the cam is provided with a locking protrusion. The adjusting shaft is driven to rotate by a hexagonal wrench. During the rotation of the cam, the base moves relative to the adjusting shaft.
[0008] The other end of the adjusting shaft is inserted into the mating hole in the fixed seat.
[0009] Preferably, the first and second identifiers are opposite each other in their initial positions.
[0010] Preferably, the force generated by the bending of the spring sheet axially locks the eccentric adjustment assembly.
[0011] Preferably, one of the radially mating shafts is inserted into the through hole of the base, and the other radially mating shaft is inserted into the mating hole.
[0012] Preferably, the base is inserted into a protrusion on the door panel assembly.
[0013] Preferably, the adjusting shaft is also provided with an anti-sway ring.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] Assemble the adjusting shaft and base into an eccentric adjusting assembly, then fix the eccentric adjusting assembly onto the door panel assembly, and then fix the mounting base. Finally, connect the eccentric adjusting assembly, the door panel assembly, and the mounting base. At this point, the door panel assembly needs to be adjusted in the Z-axis position. Use a hex wrench to drive the adjusting shaft to rotate. The cam on the adjusting shaft rotates, and during the rotation, the position of the base moves relative to the adjusting shaft. During the assembly process, the adjusting shaft rotates around the hole in the mounting base, causing the door panel assembly that needs to be adjusted to move to the target position (aligned with other assemblies). This achieves a quick adjustment to meet the overall smoothness and comfort requirements of different modules. Attached Figure Description
