Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of manual / automatic switching devices for electronic locks, specifically a manual / automatic switching device for a casement window electronic lock. Background Technology
[0002] Electronic door locks utilize programmable memory and data reading devices, making their keys difficult to copy. Each key contains a dedicated 3.5 x 3.5 mm electronic chip storing a specific password. When the key is inserted into the keyhole, the password is sent to the lock's memory, simultaneously generating a magnetic field and inducing a voltage in a coil on the chip. This voltage serves as the power source for unlocking; if the password in the key matches the lock, the lock is opened.
[0003] Application number 201921933125.4 discloses a manual / automatic switching device for a casement window electronic lock, comprising a first housing, a drive rod, a first gear, a second gear, a motor, and a handle. The first housing has an outlet, and the drive gear is disposed within the first housing. One end of the drive rod extends through the outlet of the first housing, and a transmission gear meshing with the drive gear is disposed on the drive rod located within the first housing. The rotation shaft of the drive gear extends through the first housing and is sequentially connected to the first gear and the handle. The second gear is a face gear, located below and meshing with the first gear, and its transmission shaft is connected to the output shaft of the motor. This device allows for easy switching between manual and electric operation of the door lock, making it very convenient to use.
[0004] While this setup allows for easy switching between manual and electric door lock operation, making it very convenient, the drive gear's rotating shaft extends through the first housing and connects to the first gear and handle in sequence. The second gear is a face gear, located below and meshing with the first gear. The drive shaft of the second gear is connected to the motor's output shaft, which drives the second gear, which in turn drives the first gear and handle. Under normal circumstances, manual and automatic operation can be performed simultaneously. However, in the event of a power outage or motor malfunction, the motor will be unable to drive, causing the second and first gears to jam, potentially preventing the handle from turning and resulting in instability. Therefore, based on this setup, a corresponding separation structure is incorporated for the first gear. When the motor is unable to drive, the second and first gears are separated to ensure the stability of manually turning the handle. Utility Model Content
[0005] The purpose of this invention is to provide a manual / automatic switching device for an electronic lock for a casement window, in order to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a manual / automatic switching device for an electronic lock for a casement window, including a mounting assembly, a lock body structure, and a rotating component. The mounting assembly includes a mounting plate with mounting holes on its outer wall. The purpose of this design is to install the device on the window through the mounting holes.
[0008] The lock body structure is installed on the outer wall of the mounting plate, and the purpose of this arrangement is to lock the window;
[0009] The rotating component includes a handle and a rotating rod. The handle is fixedly connected to one end of the rotating rod and is installed on the outside of the lock body structure. By rotating the handle, the rotating rod is driven to rotate, thereby controlling the lock block to rotate.
[0010] Furthermore, the lock body structure includes an inner housing, which is fixedly connected to the outer wall of the mounting plate. An arc-shaped groove is provided on the outer wall of the inner housing. The rotating rod extends into the interior of the inner housing and is rotatably connected to the inner housing. The purpose of this arrangement is to rotate the handle to drive the rotating rod to rotate, thereby controlling the lock block to rotate.
[0011] Furthermore, the mounting plate has an internal cavity, inside which a motor is installed. A housing is rotatably connected to the inner wall of the internal cavity. The rotating rod extends through the outer wall of the housing to the inner side of the mounting plate. One end of the rotating rod is rotatably connected to the inner side of the mounting plate, and one end of the housing is fixedly connected to the outer wall of the rotating rod. A torsion spring is installed between the housing and the rotating rod. One end of the torsion spring is fixedly connected to the inner wall of the mounting plate, and the other end of the torsion spring is fixedly connected to the inner wall of the housing. The purpose of this arrangement is to rotate the handle to drive the rotating rod to rotate, and to reset the rotating rod by the torsion spring when the handle is released.
[0012] Furthermore, an opening is provided on the outer wall of the mounting plate, and a locking block is fixedly connected to the outer wall of the housing. The locking block extends to the outside of the opening of the mounting plate. The purpose of this arrangement is to lock the window by means of the locking block.
[0013] Furthermore, a drive gear is installed at the output end of the motor, and a driven gear is installed on the outer wall of the rotating rod. The driven gear meshes with the drive gear. A key block is fixedly connected to the outer wall of the rotating rod, and the key block is slidably connected to the driven gear. A ring block is fixedly connected to the outer wall of the rotating rod, and the driven gear is located between the ring block and the housing. The purpose of this arrangement is to drive the drive gear to rotate through the output shaft of the motor, thereby driving the driven gear to rotate, which in turn drives the rotating rod to rotate, controlling the locking block to rotate and locking the window. When the driven gear rotates, the locking block rotates around the locking ring. At this time, automatic and manual operation do not affect each other.
[0014] Furthermore, a locking block is fixedly connected to the outer wall of the driven gear, and a retaining ring is slidably connected to the end of the locking block away from the driven gear. The retaining ring is slidably connected to the inner wall of the inner housing, and a pull rod is fixedly connected to the outer wall of the retaining ring. The pull rod extends to the outer side of the inner housing through the arc-shaped groove of the inner housing. The purpose of this arrangement is that when the motor is out of power or malfunctions and cannot drive the drive gear to rotate, pulling the pull rod will separate the driven gear and the drive gear. After separation, the handle can be turned to drive the rotating rod to rotate, thereby controlling the locking block to rotate.
[0015] This utility model has the following beneficial effects:
[0016] (1) By setting up a pull rod, when the motor of the casement window is out of power or malfunctions and cannot drive the drive gear to rotate, the pull rod is pulled to separate the driven gear and the drive gear. After separation, the handle is turned to drive the rotating rod to rotate and control the locking block to rotate. The opening and closing control of the casement window is realized by manually operating the rotating rod and the locking block. Even if the motor loses power or malfunctions, the casement window can be opened and closed normally by mechanical manual operation, thereby improving the stability of the device.

The purpose of this arrangement is to rotate the handle to drive the rotating rod 301 to rotate, thereby controlling the lock block 208 to rotate.
[0034] The mounting plate 101 has an inner cavity 103 inside, and a motor 104 is installed inside the inner cavity 103. A housing 105 is rotatably connected to the inner wall of the inner cavity 103. A rotating rod 301 extends through the outer wall of the housing 105 to the inner side of the mounting plate 101. One end of the rotating rod 301 is rotatably connected to the inner side of the mounting plate 101, and one end of the housing 105 is fixedly connected to the outer wall of the rotating rod 301.
