Description

Switching device

The invention relates to a switching device, in particular to a switching device using a light sensing control mechanism.

Doors are indispensable for every household. The door is equipped with switchgear, such as door locks, to prevent outsiders from entering the room casually. Traditional mechanical locks have a keyhole. After the key is inserted, turn the key to open the lock and open the door.

However, since the traditional lock has an open keyhole, it can only be prevented from people without professional training. For professionals or trained personnel, you can use a flashlight to illuminate the internal groove, copy the key according to the shape of the groove, or even open the door lock with a wire, resulting in a large safety hazard.

In view of this, it is necessary to provide a switching device capable of preventing cracking.

A switching device comprising a key, a sensing device, a controller and an electronic lock, the key comprising a signal transmitting device and a control element, wherein the signal emitting device is a plurality of arrays of illuminating light sources, the control element is for The illuminating light source of the control portion is turned on, while the other illuminating light source is turned on to obtain a illuminating pattern, and the controller is connected to the sensing device and the electronic lock signal, and the sensing device is configured to sense the signal emission. The device emits a light-emitting pattern, and when the sensing device senses that the signal emitting device emits a light-emitting pattern and matches the preset pattern signal of the controller, The controller controls the electronic lock to open, otherwise the electronic lock remains locked.

The switching device provided by the technical solution can control the plurality of illuminating light sources arranged in the array to be turned on by using a plurality of illuminating light sources arranged in the array as the signal emitting device, and the remaining illuminating light sources are turned off, thereby causing the signals to be turned on.

1 is a schematic view of a switch device according to an embodiment of the present invention.

FIG. 2 is a schematic diagram of the illuminating patterns appearing successively to the signal emitting devices of the switching device of FIG. 1. FIG.

Referring to FIG. 1 , a switch device 10 according to an embodiment of the present invention includes a key 12 , a sensing device 14 , a controller 16 , and an electronic lock 18 .

The key 12 includes a body 121, a signal transmitting device 122, and a control element 123. The body 121 has opposite first end faces 1211 and second end faces 1212. The plurality of signal emitting devices 122 are disposed on a side of the first end surface 1211. In this embodiment, the signal emitting device 122 is a plurality of illuminating light sources 1221 arranged in an array of the first end faces 1211. In this embodiment, the illuminating light source 1221 is a laser diode (LD) or a light emitting diode (LED). The illuminating light source 1221 of the control portion emits light while being controlled while the other illuminating light sources do not emit light, so that the plurality of illuminating light sources 1221 arranged in the array assume a predetermined pattern. Since the light emitted from the laser diode is collimated and the light is concentrated, it is further ensured that the pattern formed is more resolved and more complicated.

The control element 123 is disposed on the second end surface 1212 of the body 121 and is in signal communication with the signal generating device 12. The control element 123 is configured to control whether the signal transmitting device 122 emits light and generate a transformed graphic. The user controls the signal transmitting device 122 to generate a pattern by pressing the switch 1231 of the control element 123. In this embodiment, by encoding the control element 123 in advance, the control element 123 controls the signal transmitting device 122 to successively change to appear different patterns. That is, as shown in FIG. 2, when the switch 1231 is pressed, the control element 123 controls the turning on or off of the plurality of illuminating light sources 1221 of the signal transmitting device 122, so that the plurality of illuminating light sources 1221 arranged in the array are presented in time series. The first pattern 30, the second pattern 40, and the third pattern 50. At least two of the first pattern 30, the second pattern 40, and the third pattern 50 are not the same. It can be understood that the number and sequence of the light-emitting patterns formed can be set according to different switching devices.

The sensing device 14, the controller 16, and the electronic lock 18 may be disposed within the door body 20. The sensing device 14 is configured to sense light generated by the signal transmitting device 122, and the sensing device 14 corresponds to the signal transmitting device 122. In this embodiment, the sensing device 14 is a light sensor, and specifically may be a photosensitive diode. The controller 16 is in signal communication with the sensing device 14 and is used to determine whether the signal detected by the sensing device 14 matches a preset signal. That is, the controller 16 determines whether the pattern of the light emitted by the signal transmitting device 122 sensed by the sensing device 14 is consistent with the setting in the controller 16. When the pattern of the light emitted by the signal transmitting device 122 sensed by the sensing device 14 coincides with the setting in the controller 16, the surface 12 is the corresponding key, and the controller 16 turns the control electronic lock 18 on. When the pattern of the light emitted by the signal transmitting device 122 sensed by the sensing device 14 is inconsistent with the setting in the controller 16, it indicates that the key 12 is not the corresponding key, and the electronic lock 18 will not be able to be turned on.

Further, the sensing device 14 can also detect whether the pattern switching order of the light emitted by the signal transmitting device 122 matches the preset in the controller 16. That is, the controller 16 determines whether the pattern and the sequence of the plurality of lights emitted by the signal transmitting device 122 sensed by the sensing device 14 are consistent with those set in the controller 16. When the pattern and sequence of the plurality of lights emitted by the signal transmitting device 122 sensed by the sensing device 14 are consistent with those set in the controller 16, the surface 12 is a corresponding key, and the controller 16 controls the electronic lock 18 Open. When the pattern or sequence of the plurality of lights emitted by the signal transmitting device 122 sensed by the sensing device 14 is inconsistent with the setting in the controller 16, the surface of the key 12 is not a corresponding key, and the electronic lock 18 cannot be turned on and remains. Locked state.

It can be understood that the switching device 10 of the present technical solution may further include an alerting device 13 that communicates with the controller 16 when the sensing device 14 senses the pattern of light emitted by the signal transmitting device 122. When the change order is inconsistent with the setting in the controller 16, the surface of the key 12 is not a corresponding key, and the controller 16 can control the warning device 13 to emit an alarm signal such as a tweet or a flash to attract attention.

The switching device 10 provided by the technical solution can control the plurality of illuminating light sources 1221 of the array to be turned on by using the plurality of illuminating light sources 1221 arranged in the array as the signal emitting device 122, and the remaining illuminating light sources are turned off, thereby The signal transmitting device 122 is caused to emit different transformed lighting patterns, and the sensing device 14 senses the lighting pattern to determine whether the key 12 is the key of the switching device 10.

Therefore, according to the switch device provided by the technical solution, different patterns including sequentially appearing in order may be preset according to requirements, so that the opening may be increased. The complexity of the device can increase the difficulty of the switch device being cracked and increase the safety of the article protected by the light-opening device.
