When an operator holds the handle 91 to rotate the rotating shaft 92, the switch clamping piece 80 is installed on the rotating shaft 92, the lock pin plays a limiting role on the switch clamping piece 80, when at least one lock pin cannot retreat towards the smaller end of the lock pin, the large end of the lock pin cannot be separated from the locking groove, the lock pin limits the switch clamping piece 80, the switch clamping piece 80 is fixedly installed on the rotating shaft 92, the switch clamping piece 80 is limited, the rotating shaft 92 cannot rotate, and the locking function of the panel lock 1000 is achieved.

When the first driving mechanism acts in a position state that the first lock pin 1 is limited in the first locking groove 81, namely the large end of the first lock pin 1 is positioned on the first locking groove 81 of the switch card 80, the first lock pin 1 has a limiting effect on the rotation of the switch card 80; the first driving mechanism acts in a position state that the first lock pin 1 can slide out of the first locking groove 81, and the first lock pin 1 has no limit effect on the rotation of the switch card 80. In this embodiment, the first driving mechanism includes a first fixing member 130, a first driving element 110 and a pin 111, a first accommodating space and a second accommodating space are provided in the first fixing member 130, the first driving element 110 and the pin 111 are provided in the first accommodating space in a straight line, and a first elastic element 52 is provided between the first driving element 110 and the pin 111; the first lock pin 1 is disposed in the second accommodating space, and a second elastic member 51 is disposed between the first lock pin 1 and the first fixing member 130.

The first driving mechanism is the first unlocking mechanism 2000, so that the unlocking and locking functions of the panel lock 1000 according to the present embodiment are realized: specifically, the first accommodating space provides a mounting space and has a positioning function for the first driving element 110 and the pin 111, the pin 111 is arranged in the first driving element 110, the first driving element 110 is connected with the pin 111 through the first elastic member 52, and a cavity 112 capable of accommodating the pin 111 is arranged in the first driving element 110; the first lock pin 1 is arranged perpendicular to the first driving element 110, the first lock pin 1 is connected with the first fixing member 130 through the second elastic member 51, in this embodiment, a smaller end of the first lock pin 1 is placed towards the direction of the pin 111 and perpendicular to (or intersecting) the moving path of the pin 111, and a larger end of the first lock pin 1 is pressed against the switch card 80 by the elastic force of the second elastic member 51. When the first unlocking mechanism 2000 is in the locked state, the smaller end of the first lock pin 1 is blocked by the pin 111, and the first lock pin 1 has no space to retreat toward the pin 111. When the present solution panel lock 1000 is unlocked by the first unlocking mechanism 2000 (i.e., "electronic mode", in which case the "commissioning mode" is disabled, which is equivalent to the case without the "commissioning mode", which will be described below), optionally, the first driving element 110 is a solenoid, and the pin 111 is a movable iron core. The solenoid has simple structure and reliable driving, needs small driving energy and saves energy. The plunger can be sucked into the cavity under the driving of the solenoid, the pin 111 is separated from the first lock pin 1, and a sufficient space 100 is provided for the first lock pin 1 to retreat towards the pin 111, and the first unlocking mechanism 2000 is in an unlocking state.

It should be noted that, the energy of the solenoid comes from the intelligent unlocking key, the intelligent unlocking key is provided with a battery therein, the intelligent unlocking key head is provided with a coil, the electronic unlocking mechanism is provided with a coil (the coil is arranged in a groove on the panel 90 in the lock in the scheme and is positioned behind the dust cover 93, the coil is not marked in the text), the coil on the electronic unlocking mechanism is connected with the solenoid through a conductor, when the coil of the intelligent unlocking key and the coil of the electronic unlocking structure are close to each other, the intelligent unlocking key supplies power to the coil of the electronic unlocking structure by using the principle of 'electromagnetic induction' so as to supply power to the solenoid, so that the solenoid generates a magnetic field, and the movable iron core is sucked into the cavity.

When an extreme condition that the first driving element 110 is damaged is met, the first driving element 110 cannot suck the pin 111 into the cavity, in order to avoid the condition that unlocking cannot be performed, the first driving mechanism further comprises an auxiliary unlocking pin 120, the auxiliary unlocking pin 120 is arranged at one end, opposite to the pin 111, of the first accommodating space, a fifth elastic member 53 is arranged between the auxiliary unlocking pin 120 and the first fixing member 130, and at the moment, an operator can use the auxiliary unlocking pin 120 to push the pin 111 into the cavity to perform unlocking, so that reliability of functions of the panel lock 1000 is improved. Specifically, the first driving element 110 and the auxiliary release pin 120 are arranged coaxially and oppositely, the auxiliary release pin 120 is connected to the first fixing member 130 through the fifth elastic member 53, one end of the auxiliary release pin 120 facing the pin 111 is an inclined surface, the inclined surface is inclined towards the first lock pin 1 and is located on the moving path of the first lock pin 1, and a part of the other end of the auxiliary release pin 120 is exposed out of the first fixing member 130. Because the end of the auxiliary release pin 120 close to the pin 111 has an inclined surface, the end of the inclined surface of the auxiliary release pin 120 always has a protrusion, the operator pushes the auxiliary release pin 120 (fig. 14 shows that a force F is applied to the bottom of the auxiliary release pin 120), the protrusion of the auxiliary release pin 120 pushes the pin 111 into the cavity, the first lock pin 1 is separated from the pin 111, at this moment, from the cross-sectional view of the auxiliary release pin 120 and the pin 111, the inclined surface and the end plane of the pin 111 form a triangular space, which provides a space 100 for the first lock pin 1 to move backward toward the smaller end of the pin, the rotating shaft 92 is rotated, the switch card 80 pushes the first lock pin 1, and at the same time, the first lock pin 1 pushes the auxiliary release pin 120 (at this time, the operator should release the auxiliary release pin 120 to reset the auxiliary release pin 120), and moves toward the space, so that the lock pin is separated from the.

Further, a kidney-shaped hole 1201 is formed in the middle of the side surface of the secondary unlocking pin 120 along the axial direction, a limit pin 1202 penetrating through the kidney-shaped hole 1201 is arranged at a position corresponding to the kidney-shaped hole 1201 of the first fixing member 130, and the limit pin 1202 is matched with the kidney-shaped hole 1201 to install the secondary unlocking pin 120 on the first fixing member 130 and limit the moving range of the secondary unlocking pin 120.

The auxiliary unlocking pin can unlock the panel lock from the inside of the panel lock in the locked state of the panel lock. In addition, when the panel lock is in a locked state, if the first unlocking mechanism fails, a hole can be drilled from the outer side of the panel lock corresponding to the position of the secondary unlocking pin by using an electric tool, and the secondary unlocking pin can be operated by a finger to unlock. That is, the secondary unlocking pin can facilitate the reduction of the workload and the reduction of the violence degree in the violent unlocking. Because the auxiliary unlocking pin is arranged inside the panel lock, the panel lock cannot operate the auxiliary unlocking pin under the normal use state. Some panel locks among the prior art have set up urgent release mechanism, can use urgent unlocking key to pass through urgent release mechanism and carry out the unblock to the panel lock under emergency, however if urgent unlocking key does not manage and control in place, then can have stolen or abuse urgent unlocking key to the condition that leads to improper unblock takes place, has the potential safety hazard. The scheme has no emergency unlocking function, when the electronic driving mechanism fails, the panel of the panel lock needs to be damaged, and unlocking is carried out through the auxiliary unlocking pin, so that abuse of an emergency unlocking key is avoided, and the violence degree of violent unlocking is reduced.

Similarly, when the second driving mechanism acts in a position state that the second lock pin 2 is limited in the second locking groove 82, that is, the large end of the second lock pin 2 is located on the second locking groove 82 of the switch card 80, the second lock pin 2 has a limiting effect on the rotation of the switch card 80; the second driving mechanism acts in a position state that the second lock pin 2 can slide out of the second locking groove 82, and the second lock pin 2 has no limit effect on the rotation of the switch card 80. In this embodiment, the second driving mechanism includes a second fixing member 230, a third fixing member 231, a driving pin 210 and a driving pin 220, a third accommodating space and a fourth accommodating space that are perpendicular to each other are provided in the second fixing member 230, a fifth accommodating space and a sixth accommodating space that are perpendicular to each other are provided in the third fixing member 231, the second fixing member 230 and the third fixing member 231 are disposed opposite to each other, the third accommodating space and the fifth accommodating space are disposed in an opposite position, the driving pin 210 is disposed in the sixth accommodating space, the driving pin 220 is disposed in the fifth accommodating space, and a third elastic member 55 is provided between the driving pin 220 and the third fixing member 231; the second lock pin 2 is disposed in the fourth accommodating space, and a fourth elastic member 54 is disposed between the second lock pin 2 and the second fixing member 230.

The second driving mechanism is the second unlocking mechanism 3000, so that the unlocking and locking functions of the panel lock 1000 in the scheme are realized: the second unlocking mechanism 3000 is installed on the back of the panel 90, the driving pin 210 and the driving pin 220 are installed in the third fixing piece 231, the third fixing piece 231 provides an installation space for the driving pin 210 and the driving pin 220 and has a positioning function, one end of the driving pin 220 is connected with the third fixing piece 231 through the third elastic piece 55, the driving pin 210 is installed perpendicular to the driving pin 220 and extends out of the back of the panel 90, the driving pin 210 and the driving pin 220 are vertically matched, specifically, one end of the driving pin 210 close to the driving pin 220 is a protrusion 211 (semi-cylindrical shape), and the position where the driving pin 220 is matched with the driving pin 210 is a groove 221 arranged on the side surface of the driving pin 210; the position of the protrusion 211 is dislocated (i.e. eccentrically arranged) with the axis of the driving pin 210, and when the driving pin 210 rotates along the axis of the protrusion, the protrusion 211 rotates eccentrically on the end surface of the driving pin 210; the protrusion 211 is always located in the groove 221, and when the driving pin 210 rotates, the driving pin 210 controls the up/down movement of the driving pin 220, and the movement track is perpendicular to the axial movement track of the second lock pin 2. In the present scheme, when the panel lock 1000 is in a "debug mode" (in this case, the "electronic mode" is disabled, which is equivalent to no "electronic mode", and the first lock pin 1 is not matched with the first locking groove 81), the smaller end of the second lock pin 2 is close to/in contact with the driving pin 220, and the second lock pin 2 has no space for retreating. When this scheme panel lock 1000 utilizes the debugging to separate the blocked mechanical system and carries out unblock, utilize mechanical unlocking key (not marking in this scheme) and drive round pin 210 cooperation and rotate drive round pin 210, the rotation of drive round pin 210 has driven drive pin 220, make drive pin 220 take place the displacement, after drive pin 220 takes place the displacement, second lockpin 2 has broken away from the restriction of drive pin 220, second lockpin 2 has been retreated towards less end direction and has had sufficient space 200, rotate pivot 92, switch card 80 stirs second lockpin 2, second lockpin 2 takes place the displacement towards the space direction, do not play spacing effect to the rotation of pivot 92, realize the unblock function. When locked, the rotating shaft 92 is rotated to reset the switch card 80, so that the second lock pin 2 is locked in the second locking groove 82. Meanwhile, the driving pin 210 is reset through the rotation of the mechanical key, so that the driving pin 220 moves downwards to block the retraction of the second locking pin 2, and the locking is realized.

When the lock is impacted, the driving pin 220 and the pin 111 will move upwards due to the inertia force, which will cause the first lock pin 1 and the second lock pin 2 to have a space for moving to their respective small ends, and thus will be unlocked accidentally (i.e. the rotating shaft 92 can rotate).

When the lock is impacted, the driving pin 220 and the pin 111 move upwards due to the inertia force, which causes the first lock pin 1 and the second lock pin 2 to have a space for moving towards the respective small ends, and the lock is unlocked accidentally (i.e. the rotating shaft 9292 can rotate). The inertial force on the anti-impact pin 240 is opposite to the direction of the driving pin 220 and the direction of the pin 111, so that the anti-impact pin 240 moves upwards to counteract the spatial change generated when the driving pin 220 moves upwards, and the second lock pin 2 is prevented from moving towards the small end.
