Technical Field

[0001] This utility model relates to the field of vehicle structure technology, specifically to a steering wheel quick-connect structure. Background Technology

[0002] A steering wheel is a wheel-shaped device used to control the direction of travel in cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft.

[0003] In the existing technology, in order to ensure automobile production efficiency and facilitate automobile maintenance, quick-connect and modular structures are usually used to design steering wheels. However, the existing steering wheel connectors are inconvenient to install during use, making it difficult to disassemble and assemble the steering wheel. Therefore, we propose a steering wheel quick-connect structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a steering wheel quick-connect structure. This structure enables quick disassembly and assembly of the steering wheel, greatly improving the installation efficiency of the steering wheel. At the same time, the modular structure can expand the applicability of the connector, making the installation of the connector and the steering wheel more convenient, and can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steering wheel quick-connect structure, including a fixed plate, a connecting frame fixedly connected in a circumferential array on the upper surface of the fixed plate, a sleeve fixedly connected to the outer ring side of the lower surface of the fixed plate, and a threaded joint slidably connected to the outer ring side of the sleeve, the lower end of the threaded joint being threadedly connected to an external steering shaft, a movable frame hinged at the lower end of the connecting frame via a pivot shaft, the movable frame having an L-shaped structure, a mounting hole provided in the middle of the lower end of the movable frame, and a compression spring fixedly connected inside the mounting hole, the lower end of the compression spring being fixedly connected to the upper surface of the fixed plate, and a buckle fixedly connected to the inner side of the upper end of the movable frame, the buckle correspondingly engaging with the slot of the external steering wheel.

[0006] Furthermore, it also includes a limiting groove and a hoop. The limiting groove is opened on the upper part of the outer surface of the movable frame, and the hoop is sleeved on the outer ring side of the connecting frame, and the hoop is correspondingly engaged with the limiting groove.

[0007] Furthermore, it also includes a insert, which is an irregularly shaped structure. The insert is fixedly connected to the middle of the lower surface of the fixing plate, and the insert is engaged with the irregularly shaped groove opened at the upper end of the external directional shaft. The insert can effectively prevent the worker from inserting the quick connector incorrectly, thereby making the use of the quick connector safer.

[0008] Furthermore, it also includes a foolproof notch, which is fixedly connected to the middle of the rear side of the front connecting bracket, and the notch engages with the snap-fit ​​groove opened at the lower end of the external steering wheel; the notch can effectively prevent workers from installing the steering wheel incorrectly, thus making the use of the quick-connect parts safer and more convenient.

[0009] Furthermore, the outer surface of the movable frame has rounded corners, and the outer surface of the movable frame is electroplated with a nickel alloy anti-corrosion layer; the nickel alloy anti-corrosion layer on the surface of the movable frame can greatly extend the service life of the quick connectors, thereby making the use of the quick connectors safer and more convenient.
