In the gear set, a ratchet is installed above the gear 302, the ratchet is fixed on the housing, and a spring is connected below the gear 302. The upper end of the spring is fixed on the gear 302 and the lower end is fixed on the housing. The gear 303 of the gear set is connected to the second set of worm gear mechanisms through a transmission shaft, the worm gear mechanism is connected to the third set of worm gear mechanisms through the transmission shaft, and the third worm gear mechanism drives the end gear set to rotate through the transmission shaft. , The transmission chain is connected to the gear 802 in the gear set.

Further, the transmission shaft between the second set of worm gears 602 and the third set of worms 701 is mounted on a longitudinal partition with a matching bearing, and the longitudinal partition is fixed on the housing.

Furthermore, in order to prevent the gears from reversing under the opposite force when the window is kept open in the two modes, and considering the force steering problem, the design of three sets of worm gear structures can solve the above problems.

The technical solution of the present application is described below through specific embodiments.

Example 1:

As shown in Figure 1, an electric/manual dual-purpose window opener includes a motor 100. The motor 100 is fixed on the housing by screws. The end of the output shaft of the motor 100 is a worm 201. The worm 201 and the worm gear 202 are matched for transmission. 301 is connected to worm gear 202 through a transmission shaft; gears 301, 302, and 303 are gear sets arranged in parallel and fixed on their respective transmission shafts; ratchet wheel 401, ratchet wheel 402, sleeve 403, gear 302, and spring 500 together form Mode switch 400. The internal assembly principle is shown in Figure 2. The spring 500 uses elastic force to support the gear 302 and the second ratchet 402. The guide grooves on the first ratchet 401 and the second ratchet 402 slide on the same guide plate of the sleeve 403. When the ratchet one is pressed At 401, the second ratchet wheel 402 is pushed out of the guide plate. Due to the action of the spring, the teeth of the second ratchet wheel 402 will slide along the inclined surface of the teeth of the first ratchet wheel 401. Under the action of the inclined surface, the second ratchet wheel 402 will rotate one angle and slide to the other. At this time, the guide plate of the sleeve 403 is stuck in the teeth of the second ratchet 402, which realizes the sinking and self-locking of the second ratchet 402. At this time, the gear 302 is downwardly disengaged from the meshing with the gear 301 and the gear 303; When the ratchet wheel 401 is pressed again, the ratchet wheel 402 is pushed out of the guide plate of the sleeve 403. At this time, under the action of the spring, the inclined surface of the ratchet wheel 402 rotates an angle so that the guide grooves of the ratchet wheel 401 and the ratchet wheel 402 coincide. Under the action of elastic force, the two mesh and retract along the guide plate, and the gear 302 is reset at this time; in manual mode, the upper end of the gear 302 is provided with a circular track C1 that cooperates with the ball, and the lower end is fixed with the spring, so that the mode switch 400, The gear 302 and the spring 500 form a push-type spring switch, which can realize the function of pressing the gear 302 to sink and disengage the gear 301 and gear 303 once, and press it again to rebound and reset; the manual mode rotating shaft 500 is equipped with a gear 303, The half part is designed as a rectangular parallelepiped, which can be used to realize the function of manually opening and closing the window with the matching rotating handle.

The specific working process of the present invention is as follows

In the electric mode, the gear 301, the gear 303 and the gear 302 keep meshing, the motor rotates in the forward direction, and the two gear sets and two sets of worm gear mechanisms drive the chain to rotate in the forward direction, so that the chain extends out of the window opener to open the window. Because the worm gear mechanism has a self-locking function, the chain will not retract due to gravity when the window is open. The motor rotates in reverse, the chain retracts, and the window is closed.

In the case of power failure, the manual mode is used. Press the mode switch 400, the gear 302 sinks and disengages and is fixed. Use the rotating handle to drive the manual mode rotating shaft 500 to rotate. The power is only in the worm 601, worm gear 602, worm 701, and worm gear 702 , Gear 801, gear 802, can open the window. Also due to the self-locking effect of the worm gear, the gravity in the window opening state will not cause the chain to retract. Reverse rotation of the handle can close the window. After the power is restored, the mode switch 400 is pressed again, the gear 302 is reset to mesh with the gear 301 and the gear 303, and the electric mode switch window can be performed.
