The invention relates to a magnetic type limiting and unlocking assembly and an electric door closer comprising the same, the limiting and unlocking assembly comprises a limiting support, a rotating block, a permanent magnet and an unloading force maintaining mechanism, the rotating block is pivoted to an inner cavity of the limiting support, and a limiting end protruding leftwards is arranged on the lower portion of the left side of the rotating block; a limiting groove matched with the limiting end is formed in the left wall of an inner cavity of the limiting support, an electromagnet is fixed to the right side of the rotating block, an arc groove is formed in the top face of the rotating block, and the force unloading keeping mechanism comprises a force unloading spring and a ball. The invention has the advantages that the permanent magnet is directly fixed on the sliding block and is attracted with the unelectrified electromagnet during locking and limiting, that is, the electric energy is not consumed and the energy is saved in a normally-opened state, and the permanent magnet is automatically attracted and limited when the door is opened in place, so that the use is convenient; the newly-designed force unloading keeping mechanism can relieve the impact effect of forced door opening on the fixed pin shaft, the rotating block cannot be clamped by the force unloading spring, and the unexpected situation that forced door opening fails is avoided. The improved structure is simpler, the number of parts is small, and cost is reduced.
本发明涉及一种磁吸式限位解锁组件及包含其的电动闭门器，该限位解锁组件包括限位支架、转动块、永磁铁和卸力保持机构，转动块枢接于限位支架内腔，转动块的左侧下部设有向左凸出的限位端头，限位支架内腔左壁设有与限位端头配合的限位槽，转动块的右侧固定有电磁铁，转动块的顶面设有圆弧槽，卸力保持机构包括卸力弹簧和滚珠。本发明优点为，永磁铁直接固定于滑块上且锁止限位时与未通电的电磁铁吸合，即常开门状态时不需消耗电能，节能且开门到位时是自动吸合限位，使用方便；新设计的卸力保持机构能减轻强制开门对固定销轴的冲击作用且卸力弹簧不会使转动块卡死，避免强制开门失败的意外情况出现；改进后的结构更加简单，零部件少，降低成本。
