The invention discloses a prompt tone generating structure of an oil filler cap. The prompt tone generating structure comprises an upper cap, a bayonet cap, a positioning chuck, a turntable and a return spring. The positioning chuck is circumferentially limited and matched in the bayonet cover, and a sounding ratchet is arranged on the positioning chuck; the turntable is matched on the positioningchuck, a sounding pawl matched with the sounding ratchet is arranged on the lower side of the turntable, and a linkage pawl is arranged on the upper side; the upper cover covers the bayonet cover, and a linkage ratchet matched with a linkage pawl is arranged in the upper cover; meanwhile, a limiting assembly for limiting the rotating range of the upper cover relative to the bayonet cover is arranged between the upper cover and the bayonet cover; and the reset spring is arranged between the upper cover and the positioning chuck or the bayonet cover so as to drive the rotated upper cover to reset. One click prompt tone can be achieved under a certain torque, and the oil filler cap is ensured to be prompted to be screwed in place; and a sound is clear and clear, and the sound can be continuously generated after tightening and loosening so that the problem that an operator misses to hear the prompt sound is effectively avoided.
本发明公开了一种加油口盖的提示音发生结构,包括上盖、卡口盖、定位夹头、转盘和复位弹簧;定位夹头周向限位配合在卡口盖内,并且在定位夹头上具有发声棘齿;转盘配合在定位夹头上,并且在转盘的下侧具有与发声棘齿配合的发声棘爪,上侧具有联动棘爪;上盖罩设在卡口盖上,在上盖内具有与联动棘爪配合的联动棘齿;同时在上盖和卡口盖之间设置有限定上盖相对于卡口盖转动范围的限位组件;复位弹簧设置于上盖与定位夹头或是卡口盖之间,以带动转动后的上盖复位。本发明可在一定扭矩下实现一声咔嗒提示音,确保提示加油口盖拧紧到位;而且发声清脆明朗,并在拧紧松开后还可继续发声有效避免了操作人员漏听提示音的问题。
