2results about How to "Play a guiding effect" patented technology

This application relates to the field of lawnmower technology, and in particular to a high-efficiency heat-dissipating lawnmower drive mechanism and a lawnmower. The high-efficiency heat-dissipating lawnmower drive mechanism includes a first mounting box, a transmission assembly, a stator, a rotor, a second mounting box, a circuit board, and an airflow generating assembly. Compared to existing high-efficiency heat-dissipating lawnmower drive mechanisms, mounting the stator, rotor, and circuit board on the same side of the first mounting box, with relatively close proximity, facilitates coordinated heat dissipation. The airflow generating assembly drives the airflow around the rotor, rapidly expelling hot air from the stator through heat dissipation holes, ensuring effective heat dissipation for both the stator and rotor. The airflow generating assembly also drives the airflow around multiple heat dissipation fins, rapidly cooling the heat dissipation fins and consequently rapidly cooling the circuit board, ensuring effective heat dissipation for the circuit board.

The utility model relates to hinge technical field, and disclose a kind of hinge and door and window for improving sealing, including first mount and second mount for fixed installation, first mount side is equipped with several first axle seat, and several first axle seat are rotatably connected with first rotating piece between, and first rotating piece side is rotatably connected with second rotating piece, and second rotating piece side is rotatably connected with connecting shaft, and second mount is fixedly connected with connecting shaft.The utility model in the middle part position of when opening and closing piece is completely closed in fixed frame body, since opening and closing piece is equipped with the hinge, it plays to prevent the position between fixed frame body and opening and closing piece from appearing deformation condition, improve the sealing effect after fixed frame body and opening and closing piece close, simultaneously, through the hinge can share the load-bearing performance of two guide hinges of fixed frame body and opening and closing piece upper and lower position, improve the stability after fixed frame body and opening and closing piece installation.
