Description

CONSTRUCTIVE ARRANGEMENT APPLIED IN ELECTRONIC PADLOCK MECHANISM

TECHNICAL FIELD [0001] The present utility model reveals a constructive arrangement applied to an electronic padlock mechanism, capable of automating a conventional padlock, replacing the core of a standard padlock with an electromechanical core.

MODEL HISTORY [0002] The lock is an object that blocks access to a particular object, usually made of brass, widely known and used in doors, windows, drawers, etc. To open a conventional lock, it is necessary to insert its corresponding key, which, when aligned with the secret pins inside the cylinder, allows the rotation of the cylinder, moving the tongue and releasing the rod, opening the lock. This mechanism is completely mechanical, without the intervention of electronic or electrical circuits.

STATE OF THE TECHNIQUE [0003] In the current state of the art, some well-known proposals have several padlock provisions, such proposals can be found:

[0004] In document US 2012001902, a padlock with electronic drive is proposed, where the said electronic system drives a motor that moves the meat mechanism. However, this device uses rollers to lock the rod and another problem,

Petition 870180057829, of 07/04/2018, p. 8/18

2/6 even greater is the fact that it is necessary to start the engine to release the rod and another engine start to lock the rod.

[0005] In document US 2016/0217637 an electronic padlock is proposed, comprising a body, a rod, a locking mechanism operated by an electronic circuit that makes interactions with a mobile device. However, this device uses spheres to perform the locking of the padlock, in addition, due to the complexity and the number of components, the body of the padlock is geometrically disproportionate to the rod, limiting mobility and its use.

[0006] The document US2017009491 discloses a padlock with an electronic circuit connected to a communication network system such as bluetooth or other electronic means. However, the document requires protection of the physical locking system, and the device uses a threaded locking system.

[0007] All state-of-the-art documents reveal padlocks manufactured and developed specifically for the accommodation of circuits and electromechanical elements. No document reveals or displays evidence of an automated padlock or a system for automating conventional padlocks with tongue locking.

OBJECTIVE OF THE MODEL [0008] The present utility model aims to circumvent the disadvantages of the state of the art,

3/6 featuring a mechanism capable of automating the conventional padlock, replacing the standard padlock core, eliminating the need to use a physical key to perform the opening, transforming a standard mechanical padlock into an electronic padlock.

[0009] The requested utility model provides simplicity of design and a more efficient device in relation to the state of the art, as it uses the structure of a conventional padlock. Still, it differs from the previous ones in that it is not necessary to activate the motor after the opening of the locking rod to perform the locking of the rod, as it uses a system of springs that keep the tongue always pressed, making it possible to close the locking rod. right after opening, without an additional activation of the electric motor.

MODEL DESCRIPTION [0014] The mechanism shown in figure 1 consists of a padlock body (1), a rod (12) mounted on the padlock (1), a spring (3) of the tongue located at the end of the tongue (2) , both located inside said padlock (1). The tongue (2) is mounted on a trigger (4) of the tongue and its access is protected by the cover (11), located on the side of the padlock (1). In the center of the padlock (1) there is an electric gearmotor (6) inserted in an adapter jacket (5) and the actuator (4) of the tongue coupled to the gearmotor (6), these components being responsible for the automation of the padlock (1). The gearmotor (6) is connected to the electronic board (7) with a bluetooth receiver, which uses the energy supplied by the battery (8) and also contains a button (9). The plastic protective covers (10) house all the mechanisms previously mentioned inside.

[0015] Figure 2 shows the electronic padlock mounted with the automation mechanism, where the spring (3) of the tongue is pressing on the tongue (2) making it possible to close the rod (12) without the need to activate the gearmotor (6).

[0016] Figures 3 and 4 illustrate a sectional view of a conventional padlock and an exploded view of the conventional padlock exposing the core (13), respectively, showing the similarity and peculiarity between the conventional padlock and the model requested.

[0017] To perform the automation of the padlock

5/6 and make it electronic, it is proposed by the present utility model to replace the conventional mechanical drive system (core (13)) with a set consisting of a tongue driver (4), an adapter jacket (5) and a gearmotor (6) connected to the electronic circuit board (7) with a bluetooth receiver that communicates with a mobile device through an application.

[0018] The electronic padlock remains in standby mode constantly and is awakened from the moment the button (9) is activated, emitting an informational signal, indicating that the padlock is able to communicate with the application installed in a mobile device. Thus, it is possible to open the lock without the need for a physical key, being necessary to wake up the system, pair the mobile device with the lock and select on the mobile device screen the command to open the lock.

[0019] The application communicates via bluetooth with the electronic card (7), which in turn emits a

drive for the electric gearmotor (6). [0020] To trigger the gearmotor (6) O trigger (4) is rotated, doing with that tongue (2) is recessed, compressing the spring (3), allowing The release of rod (12), opening the padlock (D ·

[0021] After releasing the rod, the same command is configured to return the actuator (4), decompressing the spring (3), which in turn allows the return of the tongue (2) to the initial position. Thus, to lock the padlock (1), locking the rod (12), it is not necessary to

6/6 operation on the gearmotor (6), just push the rod (12) against the tongue (2) and overcome the spring force (3), as in a conventional lock and different from the state of the art.

[0022] The actuator (4) of the tongue has a cylindrical shape, with an eccentric recess on its lower face limiting movement, thus it is possible to use a standard electric motor (6), of direct current. In addition, said actuator (4) of the tongue has an eccentric recess in its upper face, which allows the fitting for the movement of the tongue (2).

[0023] The adapter sleeve (5) is geometrically cylindrical, developed to be able to accommodate the gearmotor (6) in the bottom hole of the lock (1), keeping the set stable and firm. In addition, the upper face of the jacket (5) has a shoulder that limits the angular movement of the actuator (4) of the tongue.
