Description
Technical Field
The present invention belongs to the field of window opener technologies, and specifically, to a press-type spring switch mechanism and an electric/manual switchable window opener thereof.
Related Art
Disclosure of the related art information is only intended to increase the understanding of the overall background of the present invention, and is not necessarily regarded as an acknowledgement or in any form suggesting that the information constitutes the prior art known to a person of ordinary skill in the art.
Currently, an electric skylight window is powered by a solar storage battery or a domestic grid, and can be conveniently opened or closed in combination with a remote control, to greatly facilitate indoor ventilation and lighting. A special situation such as insufficient sunlight radiation, a remote control loss, or a power failure may cause a failure in an electric window opener or even cause a severe potential safety hazard. A conventional manual window opener does not provide the convenience of automatically opening or closing a window, and the window can only be opened manually, resulting in inadequate anti-theft security. Due to the foregoing problems, an electric-only window opener or a manual-only window opener cannot satisfy requirements of the market.
To overcome the deficiency of the window opener with a single control mode in commercial application, the present invention specifically discloses a design scheme of a structure of an electric/manual dual-purpose window opener. The structure remedies the functional defect of the window opener with a single opening mode, and is applicable to opening and closing of a window in various scenarios, thereby improving the safety of the product and providing adequate practicality.
To achieve the foregoing technical objective, the present invention adopts the following technical solutions:
An electric/manual switchable window opener is provided, including: a housing, a motor 100 being provided inside the housing, where a first worm and worm gear mechanism (201, 202) is connected to an output shaft of the motor 100, and the first worm and worm gear mechanism (201, 202) is connected to a first gear 301 by a first transmission shaft I; the first gear 301, a second gear 302, and a third gear 303 are arranged in parallel, are sequentially engaged with each other, and are respectively fixed on the first transmission shaft I, a second transmission shaft II, and a manual-mode rotating shaft 900 that correspond thereto;
the bottom of the second gear 302 is connected to a bottom surface of the housing by a spring 500, the top of the second gear 302 is connected to a second ratchet 402 by the second transmission shaft II, and the second ratchet 402 and a first ratchet 401 fit and are disposed in a sleeve 403;
the first ratchet 401 is cylindrical, and includes a plurality of first cam surfaces arranged along a circumference and facing the spring, the plurality of first cam surfaces are arranged relative to an axial direction of the sleeve 403 in a tilted manner, and each cam surface is provided with one first guide groove;
the second ratchet 402 is cylindrical, and is provided with a plurality of second cam surfaces corresponding to the first ratchet 401 and arranged along a circumference, the plurality of second cam surfaces are arranged relative to the axial direction of the sleeve 403 in a tilted manner, and every two cam surfaces are provided with a second guide groove;
a front end of the first cam surface is engaged with that of the second cam surface; and
the sleeve 403 is a hollow cylinder, an inner wall of the sleeve is provided with a guide plate B1, and the first guide groove and the second guide groove slide longitudinally along the guide plate.
A lower end of the manual-mode rotating shaft 900 of the third gear 303 is a second worm and worm gear mechanism (601, 602), the second worm and worm gear mechanism (601, 602) is connected to a third worm and worm gear mechanism (701, 702) by a third transmission shaft III, the third worm and worm gear mechanism (701, 702) is connected to a fourth gear 801 by a fourth transmission shaft IV, the fourth gear 801 is engaged with a fifth gear 802, and the fifth gear 802 is engaged with a chain.
In some embodiments, a lower half part of the second ratchet 402 is a hollow cylindrical structure with a ball embedded at the bottom; and a self-locking ratchet structure is provided inside an upper half part of the second ratchet. The ball disposed at the bottom of the second ratchet 402 fits an annular rail Cl on an upper surface of the gear 302, thereby reducing the impact and damage of the ratchet to the second gear 302 during self-locking.
That "the first worm and worm gear mechanism (201, 202) is connected to a first gear 301 by a first transmission shaft I" in this application refers to that the gear 301 and the worm gear 202 are two ends of one workpiece, and the worm 201 is engaged with the worm gear 202. As an integral workpiece, the gear 301 rotates as the worm gear 202 rotates.
A manner of transmission between "the third worm and worm gear mechanism (701, 702) is connected to a fourth gear 801 by a fourth transmission shaft IV" in this application may be similar to a manner of transmission between "the first worm and worm gear mechanism (201, 202) is connected to a first gear 301 by a first transmission shaft I".
In some embodiments, an upper end of the manual-mode rotating shaft 900 is a cuboid, so that a function of manually opening and closing a window can be implemented by using a rotating handle fitting the manual-mode rotating shaft.
In some embodiments, an upper surface of the gear 302 is provided with an annular rail C1, and the annular rail may fit the ball disposed at the bottom of the second ratchet 402, thereby reducing the impact and damage of the ratchet to the second gear 302 during self-locking.
In some embodiments, the transmission shaft between the worm gear 602 and the worm 701 is mounted on a longitudinal partition plate in combination with a bearing, and the longitudinal partition plate is fixed on the housing, to ensure that when a window is opened or closed manually, a torsional force from the manual-mode rotating shaft 900 is effectively transferred to the worm gear 602 and the worm 701.
It is found through research in this application that if insufficient guide plates are disposed in the sleeve, in a process in which the first ratchet 401 and the second ratchet 402 slide along the guide plates, the guide plates are subject to a nonuniform force, leading to severely affected service life. If excessive guide plates are disposed in the sleeve, a friction generated when the first ratchet 401 and the second ratchet 402 slide along the guide plates is relatively large, leading to increased wear. Therefore, in some embodiments, an inner side of the sleeve is provided with three guide plates disposed in parallel at equal intervals, so that the first ratchet 401 and the second ratchet 402 slide along the guide plates in a quick, smooth, and stable manner.
In some embodiments, when the first ratchet 401 is pressed, the second ratchet 402 is pushed out of the guide plate, teeth of the second ratchet 402 slide along bevels of teeth of the first ratchet 401 under the action of the spring, and the second ratchet 402 rotates by an angle under the action of the bevels to slide to another side, to enable the guide plate of the sleeve 403 to be clamped in the teeth of the second ratchet 402, so that the second ratchet 402 sinks and is self-locked. The second ratchet 402 sinks and is self-locked, to disconnect a motor drive path of the window opener, thereby manually adjusting the window opener.
The present invention further provides a press-type spring switch mechanism, including: a first ratchet 401, a second ratchet 402, a sleeve 403, a gear 302, and a spring 500, where the gear 302 is connected to a bottom surface of a housing by the spring 500, the gear 302 is connected to the second ratchet 402 by a second transmission shaft II, and the second ratchet 402 and the first ratchet 401 fit and are disposed in the sleeve 403;
the first ratchet 401 is cylindrical, and includes a plurality of first cam surfaces arranged along a circumference and facing the spring, the plurality of first cam surfaces are arranged relative to an axial direction of the sleeve 403 in a tilted manner, and each cam surface is provided with one first guide groove; the second ratchet 402 is cylindrical, and is provided with a plurality of second cam surfaces corresponding to the first ratchet 401 and arranged along a circumference, the plurality of second cam surfaces are arranged relative to the axial direction of the sleeve 403 in a tilted manner, and every two cam surfaces are provided with a second guide groove; a front end of the first cam surface is engaged with that of the second cam surface; and the sleeve 403 is a hollow cylinder, an inner wall of the sleeve is provided with a guide plate, and the first guide groove and the second guide groove slide longitudinally along the guide plate.
The present invention has the following beneficial effects:
(1) Based on a design of a transmission mechanism of a conventional electric-only window opener or manual-only window opener, defects of the two window openers during actual application are remedied, so that in a specific scenario in which power is not available, a user may open the window manually, and a design of opening a window indoors ensures the safety of the user.
(2) A cross section of the manual-mode rotating shaft in the present invention is a square, and the function of opening and closing the window can be conveniently implemented by selecting a rotating handle that is internally a hollow cuboid and fits the manual-mode rotating shaft.
(3) The entire structure in the present invention may be mounted inside a window frame, and the function of opening and closing the window is implemented through stretching/retraction of a chain, which avoids damage of natural factors to the window opener, so that the service life is relatively long.
(4) The window opener is applicable provided that there is an appropriate mounting space inside the frame of the window.
(5) This application has a simple structure, low costs, and universality, which is beneficial for mass production.

As described in the Related Art, for a current problem that a window opener with a single control mode has a potential safety hazard, the present invention provides a structural design of an electric/manual dual-purpose window opener, including a motor. The motor is fixed on a housing, and a worm and worm gear mechanism is connected to an output shaft of the motor, so as to transfer a force to a gear set formed by three gears arranged in parallel. A ratchet is mounted above a gear 302 in the gear set, and the ratchet is fixed on the housing. A spring is connected below the gear 302. An upper end of the spring is fixed on the gear 302. A lower end of the spring is fixed on the housing. A gear 303 in the gear set is connected to a second worm and worm gear mechanism by a transmission shaft, and the second worm and worm gear mechanism is connected to a third worm and worm gear mechanism by a transmission shaft. The third worm and worm gear mechanism further drives a distal gear set by a transmission shaft to rotate, and a transmission chain is connected to a gear 802 in the gear set.
Further, a lower half part of a second ratchet 402 is a hollow cylindrical structure with a ball embedded at the bottom, and a self-locking ratchet structure is provided inside an upper half part of the second ratchet. In combination with the spring, the gear 302 may sink and be self-locking when a switch is pressed, and the gear 302 is restored to an original position when the switch is pressed again, to implement switching between an electric mode and a manual mode.
Further, an upper part of the shaft fitting the gear 303 is designed as a cuboid structure, and a lower part of the shaft fits a bearing.
Further, an upper surface of the gear 302 is provided with an annular rail Cl, and the annular rail may fit a ball disposed at the bottom of a mode change-over switch, to protect the switch during the rotation of the gear.
Further, the transmission shaft between a worm gear 602 in the second worm and worm gear mechanism and a worm 701 in the third worm and worm gear mechanism is mounted on a longitudinal partition plate in combination with a bearing, and the longitudinal partition plate is fixed on the housing.
Further, to prevent gears from reversely rotating under an opposite action force when the window is in an open state in two types of mode, and in consideration of the problem of force shifting, the foregoing problems can be resolved by designing three worm and worm gear mechanisms.
The technical solutions of this application are described below by using specific embodiments.
Embodiment 1
As shown in FIG. 1, an electric/manual dual-purpose window opener is provided, including: a motor 100, the motor 100 being fixed on a housing by a screw. A worm 201 is disposed at a distal end of an output shaft of the motor 100, the worm 201 fits a worm gear 202 for transmission, and a gear 301 is connected to the worm gear 202 by a transmission shaft. The gear 301, a gear 302, and a gear 303 are arranged in parallel, to form a gear set, and are fixed on respective transmission shafts. A first ratchet 401, a second ratchet 402, a sleeve 403, a gear 302, and a spring 500 together form a mode change-over switch 400. FIG. 2 shows a principle diagram of internal assembly. The spring 500 supports the gear 302 and the second ratchet 402 by using an elastic force, and guide grooves in the first ratchet 401 and the second ratchet 402 slide on the same guide plate of the sleeve 403. When the first ratchet 401 is pressed, the second ratchet 402 is pushed out of the guide plate. Teeth of the second ratchet 402 slide along bevels of teeth of the first ratchet 401 under the action of the spring, and the second ratchet 402 rotates by an angle under the action of the bevels to slide to another side, to enable the guide plate of the sleeve 403 to be clamped in the teeth of the second ratchet 402, so that the second ratchet 402 sinks and is self-locked. In this case, the gear 302 is detached downward to be engaged with the gear 301 and the gear 303. When the first ratchet 401 is pressed again, the second ratchet 402 is pushed out of the guide plate of the sleeve 403. In this case, bevels of the teeth of the second ratchet 402 rotate by an angle under the action of the spring, so that the guide grooves of the first ratchet 401 and the second ratchet 402 coincide with each other. The first ratchet and the second ratchet are engaged with each other under the action of an elastic force, and retract along the guide plate. In this case, the gear 302 is restored to an original position. In a manual mode, an upper end of the gear 302 is provided with an annular rail C1 fitting a ball, and a lower end of the gear is fixed on the spring. In this way, the mode change-over switch 400, the gear 302, and the spring 500 form a press-type spring switch, which can implement a function that when a press operation is performed once, the gear 302 sinks and is disengaged from the gear 301 and the gear 303, and when the press operation is performed again, the gear rebounds and is restored to an original position. A manual-mode rotating shaft 900 is provided with the gear 303. An upper half part of the manual-mode rotating shaft is designed as a cuboid, which can implement, by using a rotating handle fitting the manual-mode rotating shaft, a function of manually opening and closing a window. A worm 601 is mounted on a lower half part of the manual-mode rotating shaft, and a worm gear 602 is engaged with the worm 601. A worm 701 and the worm gear 602 are mounted at two ends of the same transmission shaft, and a worm gear 702 is engaged with the worm 701, and transfers a force to a gear 801 by a transmission shaft. The gear 801 is engaged with a distal gear 802, and the gear 802 is engaged with a chain, to control the stretching/retraction of the chain, thereby implementing the function of opening and closing the window.
A specific working process of the present invention is as follows:
In an electric mode, the gear 301, the gear 302, and the gear 303 remain in an engaged state, and the motor rotates in a forward direction, and drives, by two gear sets and two worm and worm gear mechanisms, the chain to rotate in the forward direction, to enable the chain to stretch out the window opener and to open the window. Because the worm and worm gear mechanisms have a self-locking function, when the window is in an open state, the chain does not retract due to the gravity. The motor rotates in a backward direction, and the chain retracts, to close the window.
In a power failure scenario, a manual mode is used. The mode change-over switch 400 is pressed, and the gear 302 sinks to be disengaged and fixed. The manual-mode rotating shaft 500 is driven by the rotating handle to rotate, and power is only transferred to the worm 601, the worm gear 602, the worm 701, the worm gear 702, the gear 801, and the gear 802. Therefore, the window may be opened. Similarly, due to a self-locking function of the worm gear and worm, when the window is in an open state, the gravity does not cause the chain to retract. The window may be closed by reversely rotating the handle. After power is restored, the mode change-over switch 400 is pressed again, and the gear 302 is restored to an original position, and is engaged with the gear 301 and with the gear 303 again, so that the window may be opened and closed through the electric mode.
