Description

Reminder to remove the key device

The invention relates to the technical field of a key, in particular to the technical scope of the key device.

According to the development of the industrial and commercial society, the problems of unemployment, inequality between the rich and the poor are becoming more and more serious, and the situation of stealing other people’s property by stealing is increasing. In order to protect personal belongings, people will install locks on personal items such as houses and cars to prevent thieves from invading and stealing.

However, sometimes it is the loss of the owner of the property, causing theft of others and causing theft. For example, the vehicle key is not pulled out, causing the vehicle to be easily stolen by others, resulting in financial losses. Therefore, the manufacturer has created a new patent No. M459271. "Key reminder device" to prevent this from happening.

However, the conventional reminder device activates the speaker and the illuminator when the lock is unlocked, and the speaker and the illuminator are interrupted when the lock is blocked. If the road to be opened/riding is far away, the speaker and the illuminator will always be accompanied. The warning is easy to interfere with the driver's attention. Secondly, it is easy to exhaust the battery power. Therefore, the above-mentioned M459271 "Key Removal Device" is not practical.

In view of the problem of the conventional "keying device for reminding the key", the inventor has invented a reminder to remove the key device, so the main purpose is to provide: the warning mechanism is activated when the key is in the unplugged state. One reminder is to remove the key device; the secondary purpose of the present invention is to remove the key device like a reminder of the Swiss knife storage key.

The present invention is directed to the removal of the key device for the above purpose, and uses the following technical means: a key body having one end as a tooth portion and the other end as a joint portion; a grip is connected to the joint portion of the key body; A control unit is disposed inside the grip, and further comprises a substrate and a positive reversal sensor extending outside the substrate; and the substrate further comprises a control chip, a warning device, a battery, and a touch sensor switch The foregoing components are electrically connected to each other and constitute a warning system; and a control program is disposed in the control chip and receives signals of the touch sensing switch and the positive reversal sensor, and the control program is based on the signal As a mechanism for judging whether or not the key is removed, the control program activates the alarm when the control program determines that the key has not been removed.

The grip is pivotally connected to the joint portion of the key body, and the key body can be folded and received.

The above-mentioned reminder pulls out the key device, wherein the key body and the grip are pivotally connected together by a rotating shaft assembly, and the rotating shaft assembly is respectively connected by a rotating shaft to a pop-up button, a resilient washer, and a spring The torsion spring is further provided with a locking mechanism between the key body and the grip.

The substrate further extends from a power switch external to the substrate, and the power switch is disposed between the key body and the handle. When the key body is turned on, the power switch is turned on to supply power to the warning system.

The forward reversing sensor system further includes a forward micro switch and a reverse micro switch, and the forward micro switch and the reverse micro switch are respectively disposed between the side of the key body and the grip, and respectively located on the rotating shaft The upper and lower parts of the assembly are used to sense the forward rotation and reverse rotation of the key body.

After the reverse microswitch is touched, if the touch sensor senses that the finger leaves the conductor of the sensing end (side cover), the control program activates the alerter.

After the foregoing warning device is activated for a period of time, the power is automatically turned off.

The locking mechanism is characterized in that the key body is provided with a side block, and is locked and fixed in a recess of the grip by the thrust of the torsion spring, and the pop-up button can be pressed when the ball is used. The side block of the key body is pushed away from the recess of the grip.

The warning device further includes a warning light or/and a speaker.

The invention reminds the pulling out of the key device, and by using the above technical means, the following effects can be achieved:

1. The control program in the control unit of the present invention, when receiving the activation signal of the reverse micro switch, if the touch sensing switch senses the signal of the finger leaving, the control program causes the warning device to respond to the action. Remind the driver, and automatically turn off the power after the warning device is activated for a period of time, so as to avoid the situation that the warning device still responds after the user has not removed the key, and the invention can save a lot of power and reduce the battery replacement. Frequency of.

2. The invention adopts a folding mechanism similar to a Swiss knife storage key, which can accommodate the key body for convenient carrying. When the pop-up button is pressed, the key body can be popped up and the power switch is activated to supply power to the interior. The substrate, in order to activate the flash or sound warning mechanism of the present invention, is quite practical and convenient.
