[ detailed description ] embodiments
The invention relates to an anti-collision intelligent padlock, which comprises a lock body 1, a lock ring 2, a lock tongue 3, a lock tongue spring 4, a lock ring spring 5, a control circuit 6, an energy storage capacitor or battery 7, a lock tongue state sensor 8, a motor 9 and an antenna 10 arranged on the lock body 1, wherein the lock tongue 3, the lock tongue spring 4, the lock ring spring 5, the control circuit 6, the energy storage capacitor or battery 7, the lock tongue state sensor 8 and the motor 9 are arranged in the lock body 1, the structures are basically the same as the structures of the intelligent padlock which is currently unlocked by spring resetting and motor driving (for example, the energy storage capacitor or battery 7 supplies energy to the control circuit and the motor, the state sensor 8 is connected to the control circuit 6 and is used for detecting the unlocking state, the lock ring spring 5 is used for bouncing the lock ring when unlocking. The difference is that: the motor 9 drives the bolt 3 to horizontally slide out of the locking port 21 of the lock ring 2 through an unlocking wheel 20 with an eccentric convex column 201 to unlock; a convex column movable groove 31 for the convex column 201 to fall into is arranged on the lock tongue 3; a torsion spring 30 is provided in the unlocking wheel 20; after the unlocking wheel 20 is sleeved on the motor shaft 91 of the motor 9, the exposed stress end 301 of the torsion spring 30 is connected with the motor shaft 91 of the motor 9 in a stress way; when the lock ring 2 is to be locked, the motor 9 rotates a certain angle to make the torsion spring 30 generate a certain torque force and simultaneously drive the eccentric convex column 201 to rotate from the unlocking position 311 to the anti-collision position 312 of the convex column moving slot 31, so that the sleeve hole 202 of the unlocking wheel 20 and the motor shaft 91 of the motor 9 are in radial clearance fit (namely the sleeve hole and the motor shaft are loosened in the rotating direction to form a relative rotating space with a certain angle) to make the torsion spring generate prestress; when the lock ring 2 is to be unlocked, the motor 9 drives the boss 201 of the unlocking wheel 20 to rotate from the anti-collision position 312 of the boss moving slot 31 to the unlocking position 311 and act on the unlocking position 311.
The control circuit 6 is basically identical to the circuit structure in the common intelligent padlock and is not described in detail here.
The antenna 10 is arranged on the surface of the lock body 1 in a floating mode, a groove for storing the antenna is formed in the surface of the lock body 1, and an antenna cover 101 is further arranged on the groove for better protecting the antenna.
The working process of the invention is as follows:
1. when the locking state is ready for unlocking, the antenna 10 position of the lock is approached through the mobile phone NFC or the wireless energy transmission key, when the antenna induces the mobile phone NFC or the wireless energy transmission key, the control circuit 6 starts to work after converting electromagnetic waves into electric energy, and charges the energy storage capacitor or the battery 7. At the moment, the control circuit 6 simultaneously carries out data communication with the mobile phone NFC or the wireless energy transmission key through the antenna to verify authorization, if a user of the mobile phone or the wireless energy transmission key has unlocking authority, the control circuit 6 provides large electric energy through the energy storage capacitor or the battery 7 to drive the motor 9 to drive the unlocking wheel 20 to rotate towards the unlocking direction, the eccentric convex column 201 on the unlocking wheel 20 acts on the unlocking position 311 of the lock tongue 3 to enable the lock tongue to move towards the unlocking direction to be separated from the locking opening, after the lock ring 2 is separated from the lock tongue 3, the lock ring springs up under the action of the lock ring spring 5 to realize automatic unlocking, and at the moment, the state inductor 8 induces that the lock is unlocked and sends state information to the mobile phone or the wireless key through the control circuit 6.
2. When the unlocking state is ready for locking, the antenna 10 position of the lock is approached through the mobile phone NFC or the wireless energy transfer key, when the antenna 10 induces the mobile phone NFC or the wireless energy transfer key, the control circuit 6 starts to work after converting electromagnetic waves into electric energy, and charges the energy storage capacitor or the battery 7. At the moment, the control circuit 6 simultaneously carries out data communication with the mobile phone NFC or the wireless energy transmission key through the antenna 10 to verify authorization, if a user of the mobile phone or the wireless energy transmission key has a locking authority, the control circuit 6 provides larger electric energy through the energy storage capacitor or the battery 7 to drive the motor 9 to drive the unlocking wheel 20 to rotate towards the locking direction, then the convex column rotates from the unlocking position 311 of the convex column movable groove 31 to the anti-collision position 312 to give way to the space for the lock tongue to move towards the locking direction, then the lock tongue 3 moves towards the locking port 21 of the lock ring 2 under the action of the lock tongue spring 4, and at the moment, two conditions exist-the two conditions-the lock ring is locked
2-1), if the lock ring 2 is pressed and held, the lock tongue 3 is inserted into the locking port 21 of the lock ring 2 under the pushing of the lock tongue spring, so that the lock ring cannot bounce, and at the moment, the convex column 201 of the unlocking wheel 20 rotates to be close to the anti-collision position, and the locking is completed, as shown in fig. 2 and 6; then, when the state sensor 8 senses that the lock is closed, the locked state information is sent to the mobile phone or the wireless key through the control circuit 6.
2-2), if the lock ring is not pressed and kept, on the one hand, the lock tongue 3 is pressed against the outer edge of the lock ring 2, on the other hand, the convex column 201 on the unlocking wheel 20 can touch the left part of the convex column movable groove and be blocked, as shown in fig. 5, the unlocking wheel 20 stops rotating, and the motor shaft 91 stops after continuously rotating for a small extent, so that the torsion spring forms prestress, on the other hand, if the lock ring 2 is pressed and kept, the lock tongue 3 continues to slide under the action of the lock tongue spring 4 and then is inserted into the locking opening 21, at the moment, the left part of the convex column movable groove releases the obstruction to the convex column, so that the convex column swings for a certain angle after the unlocking wheel rotates under the action of the torsion spring stress, and further the convex column smoothly rotates to the position outside the anti-collision position 312 of the convex column movable groove and approaches the anti-collision position.
From the above, when the user wants to lock, no matter drive the locking mechanism to the locking position and then press the locking ring to lock through modes such as mobile phone NFC or bluetooth (including but not limited to) first, or press the locking ring first and drive the locking mechanism to the locking position to lock, locking can be realized smoothly, one hand is not needed to press the locking ring, and then the hand is released when the driving mechanism reaches the locking position, so that different use habits of people are met, and the use experience of people is greatly improved. Under the locking state, when a lawless person uses external force for impact, the anti-collision position of the lock tongue is blocked by the convex column of the unlocking wheel, so that the lock tongue cannot move towards the unlocking direction under the inertia generated by the impact, and the anti-collision is really realized, thereby improving the anti-theft performance of the intelligent padlock.
In the embodiment shown in fig. 7 and 8, the groove shape of the lug movable groove 31 is bent, and includes a longitudinal groove 313 and a transverse groove 314, and when the lock ring 2 is in the locked state, the lug 201 on the unlocking wheel 20 abuts against the bump stop 312 of the transverse groove 314; when the locking ring 2 is in the unlocking state, the convex column 201 on the unlocking wheel 20 is positioned in the transverse groove 314. When the lock ring 2 is to be locked, the motor 9 drives the eccentric convex column 201 of the unlocking wheel to rotate from the transverse groove 314 to the direction of the longitudinal groove 313, at this time, if the lock ring is not pressed, the eccentric convex column 201 can be blocked by the inner side position 315 of the longitudinal groove 313, then, the continuously working motor can twist the torsion spring to generate prestress, at this time, if the lock ring is pressed again, the bolt 3 is firstly inserted into the locking port 21 of the lock ring 2 under the action of the bolt spring 4, then the unlocking wheel rotates under the prestress action of the torsion spring to enable the convex column 201 to rotate and reset to the transverse groove 314 and then to be close to the side of the anti-collision position 312 of the transverse groove 314, so as to prevent the lock ring in a locking state from being unlocked by being impacted, and it can be seen that even if a mobile phone NFC or a wireless energy transfer key is firstly used for sending a locking instruction to an antenna, and then the lock ring is pressed down, the locking action can be realized.
Of course, the groove shape of the convex column moving groove 31 may be a linear transverse groove, as shown in fig. 9. When the lock ring 2 is to be locked, the motor 9 drives the eccentric convex column 201 of the unlocking wheel to rotate towards the locking direction, and at the moment, if the lock ring is not pressed down, the eccentric convex column 201 is blocked by the anti-collision position 312 of the transverse groove; then, the motor which continues to work can twist the torsion spring to generate prestress, at this time, if the locking ring is pressed down again, the bolt 3 is firstly inserted into the locking opening 21 of the locking ring 2 under the action of the bolt spring 4, simultaneously, the anti-collision position 312 of the transverse groove releases the blocking of the convex column, then the unlocking wheel rotates under the prestress of the torsion spring to enable the convex column 201 to be close to the side of the anti-collision position 312 of the transverse groove after being reset, and therefore the locking ring in the locking state is prevented from being unlocked due to collision. It can also be seen that even if the mobile phone NFC or wireless energy transfer key is used to send a locking instruction to the antenna, and then the lock ring is pressed, the locking action can also be realized.
At ordinary times, motor 9 drives the rotatory work of unblock wheel through torsional spring 30 transmission power, and when unblock wheel touchd the left side position (crashproof position or inboard position) of projection activity groove and can't continue to rotate, the motor shaft can also continue to rotate certain angle and twist the torsional spring and make it produce prestressing force, for this reason, after the unblock wheel cover is on the motor shaft of motor, they can rotate certain angle relatively. In this embodiment, as shown in fig. 7 and 8, the motor shaft 91 is in a cross shape; a plurality of protrusions 203 for applying force to the motor shaft 91 are arranged in the nesting hole 202 of the unlocking wheel 20, and the included angle between adjacent protrusions 203 is larger than the part of the motor shaft clamped by the adjacent protrusions, so as to leave a certain space for the motor shaft to twist the torsion spring to generate prestress.
In this embodiment, as shown in fig. 2 and 3, the locking ring 2 is provided with a rainproof structure 40 at the end close to the locking opening 21, which includes a locking ring sealing sleeve 401 that can be relatively movably sleeved outside the locking ring 2, a rainproof cap 402 and a sealing ring 403, the locking ring sealing sleeve 401 is fixed in the lock body 1 with a tight fit at the lower end (usually, ultrasonic welding is also needed), the lock body 1 is exposed at the upper end, and the sealing ring 403 is provided on the inner wall of the upper end; the rain hat 402 is a hollow pipe, the upper end of the rain hat is tightly sleeved on the lock ring 2 in a matching manner (usually, ultrasonic welding is needed), and the lower end of the rain hat covers the exposed part of the lock ring sealing sleeve 401, so that rainwater falling on the lock ring above the rain hat can flow downwards to the upper surface of the lock body along the rain hat, and even if a small part of water vapor permeates into the rain hat, the rainwater can be blocked by the sealing ring 403 and cannot continuously permeate into the lock body downwards along the lock ring; and the rainwater that falls on the lock body upper surface, because lock ring seal cover 401 exceeds the lock body upper surface and install in the lock body with tight fit, so the rainwater of lock body upper surface can't cross the infiltration of lock ring seal cover upper end and in the lock body, just so can the significantly reduced rainwater along the work that the lock ring infiltrates electric elements such as influence control circuit 6, motor 9 and state inductor 8 in the lock body to improve intelligent padlock's waterproof performance greatly, can reach IP67 protection level through the test.
Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made herein without departing from the principles and spirit of the invention as defined by the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the remainder of the disclosure, but rather to limit the scope of the disclosure to the full extent set forth in the appended claims.
