    TECHNICAL FIELD The invention relates to electric padlocks.
    In particular, the invention relates to electric padlocks in which "the electric actuator is = arranged" to turn the cam piece to release the latch parts - from the locking space.
    When the latch parts are released from the Lock mode, the electric padlock can be opened. - Prior art In known electric padlocks, an electric actuator is often used to unlock.
    The electric padlock can obtain the unlock code in different ways depending on the implementation. - The unlock code - can - be - entered - into an electric padlock - for example from a mobile phone via Bluetooth or another wireless network.
    RFID technology or NFC technology can also be used.
    The electric padlock may also have a keypad or touch screen for entering the unlock code, or the lock may have, for example, a fingerprint sensor.
    When the correct unlock code is entered into the electric padlock, the electric actuator in the lock releases the lock, allowing the padlock to be unlocked.
    When the lock is released, the padlock bracket can be - moved from the closed position to the open position, i.e. the padlock can be opened. 2 The electric actuator may be, for example, an electric motor arranged to turn the cam pieces of the N padlocks.
    The cam piece is a part which holds the latch parts against the mating holes in the handle 5 when the padlock is locked.
    When the electric padlock receives the correct o unlock code, the electric actuator rotates the cam piece (usually 90 degrees) so that E 25 - so that the recesses in the cam piece are at the latch parts.
    In this case, the latch parts - can move out of the counter recess of the handle, i.e. the locking space is released, and the S electric padlock can be opened.
    When the electric padlock is locked, the bracket is in the closed-N position and the electric actuator turns the cam piece to the locking position, thereby holding the N latch parts against the mating holes in the handle.
    The latch parts are normally spherical.
    In electric padlocks such as those described above, the electric actuator may break when it rotates the cam piece to lock the electric padlock. If, at the same time, the bracket is subjected to a jerk which tends to push the bracket into the open position, the latch parts begin to move back into the recesses in the cam piece, which in turn causes the cam piece to turn against the rotating force of the electric actuator. Turning the cam piece against the direction of rotation of the electric actuator may damage the electric actuator. BRIEF DESCRIPTION OF THE INVENTION The object of the invention is to provide an electric padlock which eliminates or - at least - considerably reduces - the possibility of breaking the electric padlock - the electric actuator when the electric padlock is being locked.

    Description of the invention Figure 1 shows an example of an electric padlock 1 according to the invention. Figure 1 shows a situation in which the electric padlock is opened and the bracket can be raised even higher than that shown in Figure 1.
    The electric padlock according to the invention comprises a body 2 and a handle 3. The body has latch parts 7, a cam piece 5 and an electric actuator 4. The electric actuator is arranged to turn the cam piece 5 to release the latch parts 7 from the locking state and to turn the cam piece 5 to keep the latch parts 7 locked. In the locking state, the latch parts 7 prevent the handle 3 from being moved to open the electric padlock. The locking state is shown in Figure 6.
    The handle 3 has recesses 3A for the locking parts. In the locking state, the latch parts 7 are partially in the recesses 3A of the handle, whereby they prevent the handle from being pulled outwards relative to the body 2. The electric padlock is therefore locked.
    The body 2 of the electric padlock 1 has spaces (such as bores) for different parts of the padlock. These states are not shown in more detail in Figures 1 for clarity. The electric padlock comprises - also parts other than those mentioned above, such as detectors 13, 14, to indicate whether the bracket is completely inside the body, whereby the electric padlock can be locked by the electric actuator 4. The electric actuator and cam piece are placed in the body in the space / bore provided and held inside the lock body by the cover part 8. for example, a cylinder with external threads which is locked to the body by a separate locking screw (not shown in the figures).
    - The figures do not show all parts of the electric padlock. The figures show the parts necessary for the description of the invention.
    o The electric actuator 4 can be directly connected to the cam piece 6 so that the electric actuator can O turn the cam piece. The electric actuator turns the cam piece to unlock the electric padlock N or to lock the electric padlock. The electric padlock may also comprise = 25 - a separate transmission part 6 between the electric actuator 4 and the shaft part 5B. In this case = the transmission part 6 transmits the turning force of the electric actuator to the cam piece 5. = The transmission part may also comprise other functions. For example, it can also act as an S blocking mechanism. The blocking mechanism allows the cam piece to be turned by an electric actuator, N but tends to prevent the cam piece 5 from being turned in another way with respect to the body 2. OF
    An embodiment of the cam piece 5 according to the invention is shown in Figure 2. The cam piece 5 comprises a shell part 5A and a shaft part 5B. The shell part has a central hole for 12 shaft parts and recesses 10 on the surface of the shell part. The shaft part 5B has a shaft pin 15 placed in the central hole 12. The shaft part also has a connecting part 19 arranged to communicate with the electric actuator 4. The diameter of the connecting part 19 may be wider than the diameter of the shaft pin, as illustrated in Fig. 2. The diameters of both the connecting part 19 and the shaft pin 15 are perpendicular to the longitudinal axis X of the shaft pin. The cam piece further comprises a spring 9 located between the shaft pin 15 and the shell part 5A. Thus, the spring is also placed in the central hole 12. In the figures, the spring is a coil spring shaped as a torsion spring, but it can also be a different type of spring.
    The spring comprises a first end 9A and a second end 9B. The first end 9A is arranged to communicate with the shell portion 5A. The second end 9B is arranged to communicate with the shaft part 5B. The spring is arranged to transmit the turning force of the electric actuator from the shaft pin 15 to the shell part 5A in the direction of said locking state. That is, the spring is arranged to transmit the rotating force of the electric actuator rotating the shaft pin through the first end 9A of the spring to the shell portion 5A to rotate it to the locking position.
    The shaft part further comprises at least one protrusion 17 on the surface of the shaft pin 15 and / or on the surface of the stacking part 19. This protrusion is arranged to transmit the rotating force of the electric actuator - from the shaft pin 15 to the shell part 5A to release the latch parts. That is, when the electric padlock is unlocked, the electric actuator 4 rotates (either directly or through the power transmission portion 6) the connecting portion 19, the protrusion (s) 17, 18 of which transmits the Q rotating force to the shell portion 5A. The force N used to open the electric padlock is thus transmitted via at least one projection 17, 18, and the force S 25 used to lock it is transmitted via the spring 9. In the embodiment of Figure 2, two projections are arranged at the base O of the shaft pin 15 against the connecting part 19.
    T E The spring is further arranged to allow the housing part 5A to turn against the turning force S of the electric actuator from the shaft pin 15 to the housing part 5A. Such a situation can occur if, at the same time, the bracket is subjected to a jerk which tends to move O
    N brackets to the open position. In the open position, the bracket can be placed on the subject so that the subject can be locked when the electric padlock is locked. Figures 3 to 5 show sectional views of the embodiment of Figure 1. Figure 3 shows how the other end of the spring 9 is arranged against the shaft pin. The shaft pin 15 may comprise a groove 16 or a recess for the second end 9B of the spring. The groove 16 can split the shaft pin from its free end side some distance towards the connecting part 19, as shown in Fig. 2. This makes the spring easy to install. In the embodiments of the figures, the second end 9B of the spring is parallel to the diameter of the shaft pin, but it can also be parallel to the longitudinal axis X of the shaft pin, for example, the shaft pin having a recess (such as a bore) for the other end of the spring. The shell part 5A, on the other hand, comprises a recess 11 for the first end 9A of the spring. The recess has a side surface 11A for transmitting a turning force between the spring end 9A and the shell portion 5A.
    Figure 4 shows how the latch parts 7 are in the recesses 10 of the shell part 5A when the electric padlock is open. Figures 3 and 5 show the direction of rotation A, in which direction - by turning the shaft pin 15 transmits the turning force of the electric actuator through the projections 17, 18 to the shell part 5A. EIi the electric padlock is opened by an electric actuator by turning the shaft part 5B and thus also the shell part 5A in the opening turning direction A. The spring 9 does not transmit the turning force. Figures 3 and 5 also show a second turning direction K, in which direction the electric padlock is locked by turning.
    Figure 6 shows the electric padlock locked. Figures 7 to 8 show sectional views of the embodiment of Figure 6. Figures 6 and 8 show how the latch parts 7 are partly in the recesses 3A of the handle and the recesses 10 of the shell part are not towards the latch parts. Thus, the shell portion 5A holds the latch portions against the slots 3A of the bracket, and the electric padlock is in the locked state. Figures 7 and 9 show the direction of rotation K towards the locking of the electric padlock. As can be seen, the spring 9 has (via the ends of the spring 9A, 9B) transferred 7 the turning force from the shaft pin 15 to the shell part 5A. As stated earlier, the pivoting force E is transmitted from the electric actuator 4 to the shaft pin 15. The projection S 17, 17 or the projections of the shaft part 5B do not transmit the pivoting force in the locking direction K, as can be seen S in Fig. 9. The central hole 12 comprises at least one recess 12A. 17 for. The recess (es) 12A is wider than the protrusion (s) 17, 18. Figures / and 9 also show the opening direction A for opening the electric padlock. Figures 10 to 14 show a situation in which the electric padlock is locked by the electric actuator 4 by turning the shaft part (and its shaft pin 15) in the turning direction -K, whereby the shell part 5A also pivots by means of a spring 9. At the same time, the bracket is jerked in the direction N, which tends to glide the bracket to the open position. In this case, the latch parts 7 tend to move back towards the recesses 10 of the shell part 5A, which in turn turns the shell part in the opposite direction (i.e. in the opening direction A) than what the electric actuator turns the shell part. The electric actuator is then subjected to a high load, which can break it. However, the spring 9 allows the shell part to turn in the opening direction A in such a situation, even if the shaft pin pivots in the locking direction K when the electric actuator is turned. In this case, only part of the jerking force is applied to the electric actuator. Figs. 11 to 13 show this situation in which - the spring 9 is tensioned due to jerking or other external force and the shell part 5A has turned in the direction of rotation A against the direction of rotation K of the electric actuator. Through the recesses 10, the force of the jerk rotates the shell part in the direction of rotation A. Fig. 14 shows the initial stage of the jerk. Figures 11 to 13 show how the spring 9 has taken on an external force (jerk) and allowed the shell part 5A to rotate in the direction of rotation A. The recesses 12A of the central hole 12 are designed to allow this rotation due to external force, as illustrated in Figure 13 N. It is desirable that the width of the central hole recess 12A is not wider. than - the width required to turn the shell part against the direction of rotation A 25 - the rotation of the electric actuator in the direction of rotation K. However, the recess / recesses 12A of the central hole 7 can also be wider.
    T = The electric padlock according to the invention can be implemented in many different ways. S For example, there may be several embodiments of the parts of the cam piece 5. As illustrated in Fig. 2 N, the connecting part 19 comprises a transfer surface 19A, through which the shaft part 5B is N 30 - arranged to communicate with the electric actuator 4. The transfer surface 19A comprises at least one recess and / or projection. Thus, the shapes of the interface can have different embodiments.
    The latch parts 7 are balls or pins, the ends of the pin of which have a hemispherical shape. The electric actuator 4 may be an electric motor or a solenoid. The use of an electric motor is usually more straightforward, but the cam piece can also be turned with a solenoid. In this case, the electric actuator 4 has some transmission to transfer the movement of the solenoid (such as the movement of the solenoid pin) into a reversing movement. Unlocking and locking the electric padlock (entering the unlock code, lock ready to be locked, locking command) is otherwise carried out in a manner known per se, so it is not described in this connection - in more detail.
    The solution according to the invention - effectively prevents the electric actuator of the electric padlock, such as an electric motor, from breaking if the bracket is subjected to an external force during the closing phase, which pulls the bracket away from the body of the electric padlock.
    The electric padlock according to the invention can be implemented in several different ways, as can be seen from the above description. Thus, the invention is not limited to the examples presented in this presentation, but can be implemented in various ways within the scope of the independent claim. O OF O OF
