Detailed Embodiments
[0018] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.
[0019] Such as Figures 1-3As shown in the figure, a multifunctional lock is provided. This lock is a TSA password lock, which includes a lock housing 10, a lock core 20 and a lock rope 30 arranged on the lock housing 10. The lock rope 30 is made of a steel cable and is used to tie around the zipper head of the luggage to lock the zipper head and prevent the luggage from being opened. The lock core 20 is a rotary password lock core with three groups of numbers. A keyhole 21 for unlocking is provided at the bottom of the lock core 20. When unlocking, the lock can be opened by inserting the key into the keyhole 21 at the bottom, or the lock core 20 can be rotated by the unlocking password to unlock.
[0020] A power supply 40, a main control circuit board 50, a weighing sensor 60, a Bluetooth chip 70, a UWB chip 80 and an alarm module 90 are arranged inside the lock housing 10. A display screen 100 and operation buttons 110 are arranged on the surface of the lock housing 10. The power supply 40 is electrically connected to the main control circuit board 50. The main control circuit board 50 is electrically connected to the weighing sensor 60, the Bluetooth chip 70, the UWB chip 80, the alarm module 90, the display screen 100 and the operation buttons 110 respectively. The Bluetooth chip 70 and the UWB chip 80 are respectively communicatively connected to intelligent electronic devices.
[0021] The power supply 40 is used to supply power to each electronic component. The power supply 40 uses a button battery. A battery compartment 11 is provided on the back of the lock housing 10. The power supply 40 is arranged in the battery compartment 11. A battery cover 12 is screwed on the battery compartment 11. A waterproof sealing ring 13 is provided between the battery compartment 11 and the battery cover 12. Through the settings of the battery compartment 11 and the battery cover 12, the replacement of the power supply 40 can be facilitated, and the waterproof function can be realized through the setting of the waterproof sealing ring 13.
[0022] One end of the lock rope 30 is lockingly connected to the lock core 20, and the other end is connected to the weighing sensor 60. When the lock is in use, the lock rope 30 is locked to the luggage, and then the lock and the luggage are lifted. At this time, the weight of the luggage can be measured in real time through the weighing sensor 60 connected to the lock rope 30.
[0023] The Bluetooth chip 70 is used to send the weighing data and anti-loss data to the intelligent electronic device. The intelligent electronic device includes a smart phone and a tablet computer with Bluetooth function and networking function. The model of the Bluetooth chip 70 is NRF52832. The positioning principle of the Bluetooth chip 70 is that the lock continuously broadcasts Bluetooth signals through the Bluetooth chip 70, and the signals contain information such as its own unique identifier. When the user leaves the broadcast range of the Bluetooth chip 70, the Bluetooth connection between the user's intelligent electronic device and the Bluetooth chip 70 of the lock is disconnected. At this time, the intelligent electronic device will record the position at the time of disconnection, so as to roughly determine the loss position of the lock. In addition, it is also possible to use the intelligent electronic device of others for positioning. When the intelligent electronic device of others enters the broadcast range of the Bluetooth signal, the intelligent electronic device of others receives the Bluetooth signal. At this time, the intelligent electronic device of others will upload the current position information to the server. Then the user can download the position information through his own intelligent electronic device to determine the approximate position of the lock.
[0024] The UWB chip 80 is used to achieve more accurate positioning. It can communicate with the intelligent electronic device with UWB function, and measure the distance and angle by sending and receiving extremely short pulse signals, so as to provide more accurate direction guidance to help the user quickly find the luggage with this lock.
[0025] The alarm module 90 has any one or both of the functions of sound alarm and light alarm. In this embodiment, the alarm module 90 only has the function of sound alarm. The alarm module 90 uses a buzzer, and the lock shell 10 is provided with a sound guide hole 14 at the position of the buzzer. When the user is separated from the luggage with this lock by a certain distance, the Bluetooth connection between the intelligent electronic device and the Bluetooth chip 70 of the lock is disconnected. At this time, the alarm module 90 emits a beeping sound to remind the user that the luggage has been left behind. In addition, when the user is near the luggage with this lock, that is, within the Bluetooth broadcast range of the lock, a positioning instruction can be sent through the intelligent electronic device to make the lock actively emit a beeping sound, so as to facilitate the user to quickly find the position of the luggage.
[0026] The display screen 100 is used to display the weight data measured by the weighing sensor 60.
[0027] The operation button 110 is used to realize operations such as turning on and off the display screen 100 and adjusting the volume of the alarm module 90.
[0028] The above embodiments are only used to conveniently illustrate the present invention. Any person with ordinary knowledge in the technical field, if without departing from the technical features of the present invention, makes local changes or modified equivalent embodiments using the technical content disclosed by the present invention, and does not depart from the technical feature content of the present invention, still belongs to the scope of the technical features of the present invention.
