In addition, consider that external battery insufficient voltage and other can not normally be the bluetooth battery lock power supply condition, this product has two kinds of schemes of unblanking when external battery can't normally be the battery lock power supply, can use handheld unlocking means 7 to realize the power supply to bluetooth battery lock and switch on and off battery lock. This box of unblanking adopts wireless coil charging technology, and when 7 front ends of handheld unlocking means were close to unlocking control box 1, pressed the button of unblanking on the handheld unlocking means 7, handheld unlocking means 7 can realize matcing with the bluetooth of bluetooth battery lock and switch battery lock. In addition, the whole battery lock system adopts high-grade waterproof measures, and the reliability and the stability of the product in outdoor use are ensured. In particular, the first and second (c) substrates,
(1) when the external power supply can normally supply power to the battery lock. The user can utilize the smart phone to realize the information transmission between the mobile phone and the battery lock through Bluetooth connection, the unlocking process of the invention is divided into two strokes, the battery in the first stage does not fall off from the frame completely, and the position of the lock pin 59 is judged through two Hall sensors on the circuit board 55 of the battery lock when the battery in the second stage can be dismounted from the frame completely.
As shown in fig. 5, the magnetic steel 54 is embedded in the latch 59 and moves with the latch 59, and the two hall sensors can detect the signal of the magnetic steel 54.
In a normal locking state, the lock pin 59 does not retract into the lock, at this time, the first hall sensor 551 detects a signal of the magnetic steel 54, and the hall sensor 2 does not detect a signal of the magnetic steel 54, as shown in fig. 6, the first lock frame 81 and the second lock frame are installed on the locked battery, the lock frame 1 and the lock pin 59 are in contact in the normal locking state, the battery is completely locked, and the lock pin 59 is clamped in the first lock frame 81;
when a user sends an unlocking instruction, the lock pin 59 retracts into the battery lock assembly 5, and the second hall sensor 552 detects a signal of the magnetic steel 54, the motor 53 immediately stops rotating, at this time, the pin head 591 of the lock pin 59 is separated from the number 1 lock frame, slides into the second lock frame 82 by the self weight of the battery and is clamped by the second lock frame 82, and the second lock frame 82 is closer to the battery assembly than the first lock frame 81.
When the user sends an unlocking command again, the motor 53 continues to rotate, the lock pin 59 continues to retract into the lock, the motor 53 does not stop moving until the cam 57 meets an obstacle and the motor 53 detects a locked signal, at the moment, the second lock frame 82 is separated from the pin head 591 of the lock pin 59, the battery can be completely taken out of the vehicle frame, and complete unlocking is realized.
After the user takes the battery off, click closing lock order in the APP, motor 53 reverse rotation this moment, lockpin 59 outwards stretches out, and when first hall sensor 551 detected magnet steel 54 signal again, motor 53 stopped rotating, lockpin 59 stop motion, and the lock was in the complete lock state of closing this moment.
Because battery lock assembly 5 is installed inside the frame, if on putting battery lock circuit board 55 with the bluetooth chip, the signal will be shielded by the aluminum hull, so will unblank main control unit and battery lock assembly 5 and separately install, bluetooth integrated chip arranges in unblanking control box 1, unblanking control box 1 and 5 line connection of battery lock assembly.
As shown in fig. 4, a hole is formed in the aluminum shell, the unlocking control box 1 is clamped on the aluminum shell, and the bluetooth signal can be normally transmitted and received from the hole.
(2) In order to prevent the vehicle-mounted battery from being unlocked under the condition of no electricity or damage, the wireless unlocking is carried out through the handheld unlocking device 7. Whether the external battery can normally supply power or not, the handheld unlocking device 7 can realize the locking and unlocking operation of the Bluetooth battery lock.
Specifically speaking, the unlocking control box 1 contains an induction coil 12, the handheld unlocking device 7 contains a coupling coil, a dry battery and a bluetooth module are arranged in the handheld unlocking device 7, when the handheld unlocking device 7 is close to the unlocking control box 1, the coupling coil is close to the induction coil 12, the induction coil 12 generates instantaneous current to supply power to a bluetooth chip and a motor 53 in the handheld unlocking device 7, the bluetooth of the unlocking control box 1 and the bluetooth of the handheld unlocking device 7 are paired, and the current generated by the induction coil 12 drives the motor 53 to rotate to open/close the lock.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
