Induction type handle lock and window

Technical Field

The utility model relates to the technical field of window switch devices, in particular to an induction type handle lock and a window.

Background Art

With the continuous improvement of the quality of life, people have higher requirements for the quality and performance of daily home furnishings. The safety performance, comfort and convenience of door and window handles in home furnishing products are increasingly valued.

Some smart casement windows on the market mainly use chains, screws, or gear sets to achieve their actions. The actions of these window openers, such as opening and closing, locking and unlocking, are determined based on the movement of the chain, the rotation of the screw, or the rotation of the gear. These structures all have a common problem, that is, their accuracy is low and they cannot accurately determine whether the window is opened/closed, locked/unlocked.

For example, patent number: CN201420169363.3 is a remote intelligent control window opening and closing system, which uses a chain for control and has low accuracy and cannot accurately determine the opening/closing, locking/unlocking of the window.

Another example is patent number: CN201810438249.9, which is an automatic window opening and closing device. It uses a transmission screw and a rotating nut for control, but also has the problem of low precision and cannot accurately determine the opening/closing, locking/unlocking of the window.

Another example is the external window opener with patent number CN202221053697.5, which uses gears to drive the swing arm to open and close the window. Similarly, there is a problem of low accuracy and inability to accurately determine whether the window is opened/closed, locked/unlocked.

The protective shell 10 is preferably made of stainless steel or aluminum to provide protection. The worm 13 is arranged at the output end of the motor 11, and the power of the motor 11 is transmitted from the worm 13→worm wheel 14→first gear set 20→clutch 30→second gear set 40 in sequence. The handle shaft 45 passes through the handle gear 42 and rotates synchronously with the handle gear 42. The handle 43 is set on the handle shaft 45 and can be manually operated when needed. The handle gear 42 and the induction disk 46 rotate synchronously. Since the induction disk 46 is provided with a plurality of first magnets 47, and the induction disk 46 can be sensed by the magnetic sensor 124 when it rotates, the magnetic sensor 124 can accurately detect the rotation angle of the handle gear 42, and then the control circuit board 15 controls the action of the motor 11 according to the collected information. The worm gear 14 and the worm structure are often used to transmit motion and power between two staggered axes. The worm gear 14 and the worm are equivalent to a gear and a rack in their middle plane, and the worm is similar in shape to the screw.

In this embodiment, there are four first magnets 47, which are distributed at equal angles on the induction disk 46. Adjacent first magnets 47 are directly arranged at an angle of 90 degrees. In this embodiment, the first first magnet 47 corresponds to 0 degrees, the second first magnet 47 corresponds to 90 degrees, the third first magnet 47 corresponds to 180, and the fourth first magnet 47 corresponds to 360 degrees. Preferably, it is in the initial state at 0 degrees, when the handle gear 42 (handle 43) rotates 90 degrees counterclockwise, it is unlocked, and when the handle gear 42 rotates 180 degrees counterclockwise, it is to open the window. When the handle gear 42 rotates 180 degrees clockwise, it is to close the window, and when the handle gear 42 rotates 90 degrees clockwise, it is locked. The number and distribution of the first magnets 47 can be set as needed, and are not unique.

Preferably, the magnetic sensor 124 is a Hall sensor or a reed switch sensor. The Hall sensor is a magnetic field sensor made based on the Hall effect. The Hall effect is a type of magnetoelectric effect. The reed switch sensor is mainly a sensor composed of a clarinet switch and a magnet or an electromagnet, and is a magnetic sensitive sensor like the switch-type Hall sensor. The worm gear 14 and worm 13 structure is often used to transmit motion and power between two staggered axes. The worm gear 14 and the worm 13 are equivalent to a gear and a rack in their middle plane, and the worm 13 is similar in shape to the screw. The control circuit board 15 is also a circuit board. Although its scope of application is not as wide as that of the circuit board, it is more intelligent and automated than an ordinary circuit board. The control board circuit board generally includes a panel, a main control board and a drive board. The control board circuit board is preferably a motor 11 control board.

Preferably, the first gear set 20 includes a first gear 21, a second gear 22, a third gear 23, a fourth gear 24, and a fifth gear 25; the worm 13 is arranged at the output end of the motor 11, and the worm wheel 14 is arranged at the first gear 21; the second gear 22 is arranged at the third gear 23; the fourth gear 24 is arranged at the fifth gear 25; the first gear 21 and the second gear 22 are meshed; the third gear 23 and the fourth gear 24 are meshed; the fifth gear 25 is meshed with the clutch 30. The second gear set 40 also includes a sixth gear 41; the sixth gear 41 is meshed with the clutch 30; the sixth gear 41 is meshed with the handle gear 42. The power transmission direction of the first gear set 20, the clutch 30 and the second gear set 40 is: motor 11→worm 13→worm wheel 14→first gear 21→second gear 22→third gear 23→fourth gear 24→fifth gear 25→first clutch tooth 31→second clutch tooth 32→sixth gear 41→handle gear 42→handle shaft 45→handle 43.

Preferably, the clutch 30 comprises a first clutch tooth 31, a second clutch tooth 32, a clutch shaft 34, a lever 35, an iron sheet 36, and a second magnet 38 having a non-magnetic outer sleeve 37; the second clutch tooth 32 has a sleeve structure 33, the inner wall of which is provided with a clutch groove 39; the second magnet 38 is arranged in the sleeve structure 33, and the iron sheet 36 covers the sleeve structure 33; the clutch shaft 34 passes through the first clutch tooth 31; the lever 35 is arranged on the clutch shaft 34, and can shift the second magnet 38 in the sleeve structure 33 into the clutch groove 39. The fifth gear 25 is meshed with the first clutch tooth 31. After the first clutch tooth 31 obtains power, the clutch shaft 34 drives the lever 35 to rotate, and when the lever 35 rotates, the second magnet 38 is shifted into the clutch groove 39 to establish a power connection, and then the second clutch tooth 32 transmits power to the sixth gear 41. During manual operation, the handle 43 is manually turned, the clutch slot 39 releases the second magnet 38, and the clutch 30 is disconnected. At this time, manual operation can be achieved by turning the handle 43. The second magnet 38 can be magnetically attracted to the iron sheet 36. This design is conducive to keeping the second magnet 38 near the clutch slot 39 at all times, shortening the response time of the clutch 30. The non-magnetic jacket 37 is wrapped around the second magnet 38, and the contact surface between the second magnet 38 and the iron sheet 36 is exposed, so that the second magnet 38 can be prevented from being adsorbed on the lever 35. The lever 35 has an inclined surface, so that the second magnet 38 can be dialed into the clutch slot 39. The non-magnetic jacket 37 can be made of plastic, rubber, or non-magnetic metal.

Preferably, the protective shell 10 includes a shell body 110 and a cover plate 120; a step 114 is provided on the inner edge of the shell body 110; the cover plate 120 covers the shell body 110, and the step 114 supports the cover plate 120; a fastener passes through the cover plate 120 and fixes the cover plate 120 to the shell body 110.

The cover plate 120 is provided with a second positioning seat 123, and the control circuit board 15 is inserted into the second positioning seat 123. The second gear set 40 and the clutch 30 are also arranged in the second groove 113. The output shaft of the motor 11 can rotate through the limited block 12. The limited block 12 is inserted into the limited opening 112, and then the first positioning seat 121 is pressed on the outer shell of the motor 11, so that the motor 11 can be firmly fixed. The control circuit board 15 can be directly inserted into the second positioning seat 123 to achieve assembly. Therefore, the interior layout of the protective shell 10 is very compact.
