The invention discloses a mounting structure of an injection molding part on a steering wheel. The mounting structure comprises two injection molding parts arranged on the steering wheel, the two injection molding parts are provided with inserting parts and bearing parts, the inserting parts and the bearing parts are matched, two L-shaped elastic hooks are symmetrically arranged at the lower end of each inserting part, and elastic positioning clamping jaws are symmetrically arranged in the middles of the outer sides of the two elastic hooks. A rectangular mounting hole is formed in each bearing part, wherein the length and the width of the mounting hole are in small clearance fit with the length and the width of the peripheries of the upper parts of the two elastic hooks. The elastic hooks are clamped on the bottom surfaces of the bearing parts after being inserted into the mounting holes, and the positioning clamping jaws are pressed on the bearing parts after being deformed. The mounting structure can reliably ensure the mounting firmness and location degree, is convenient and quick to mount, and can realize the constraint on the degree of freedom of the inserting parts in three directions; and automatic calibration can be achieved, the defects of over-positioning design and under-positioning are overcome, the cost investment can be reduced through the mounting structure, and the mounting structure can be achieved only by developing single molds of two products.

    本发明公开了一种方向盘上注塑件的安装结构,包括设在方向盘上的二个注塑件,在二个注塑件上分别设有相互配合的插接部和承接部,在插接部下端对称设有二个L型弹性挂钩,二个弹性挂钩外侧中部对称设有弹性定位卡爪;在所述承接部上设有矩形安装孔,安装孔的长度和宽度与二个弹性挂钩上部的外围长度和宽度小间隙配合,所述弹性挂钩插入到安装孔后卡在承接部底面,所述定位卡爪变形后压在承接部上面。该安装结构能够可靠的保证安装牢固性及位置度,安装方便快捷,并可实现对插接部三个方向自由度的约束;可实现自动校准,避免过定位设计及欠定位的缺陷,安装结构可实现减少成本的投入,只需通过对两个产品的单体模具开发即可实现。
