As shown in fig. 12, in the present embodiment, the locking hook 4 of the compound cam 5 is L-shaped, and the bent portion of the L-shape extends toward the connecting portion 20 of the lock pushing plate 3, so that the locking hook 4 can hook the connecting portion 20 of the lock pushing plate 3; the sector 42 of the compound cam 5 is in the same vertical plane as the connecting portion 20 of the lock pusher 3, ensuring that the sector 42 can contact the connecting portion 20. Thus, as shown in fig. 8, when the latch hook 4 of the compound cam 5 rotates to the connection portion 20, the latch hook 4 may hook the connection portion 20 to limit the latch push plate 3 to rotate along the second wheel axle 18; as shown in fig. 10, when the sector 42 of the compound cam 5 rotates to the connecting portion 20, the sector 42 may push the latch hook 4, so that the stopper 15 of the latch push plate 3 releases the hook portion 14 of the latch plate 2.

As shown in fig. 9, the rotating shaft of the compound cam 5 is installed in the installation hole 30 of the substrate 1, the motor 40 is arranged on the other side of the installation hole 30, the motor 40 is a stepping motor, the stepping motor is installed on the back of the substrate 1 through a motor base 41, and the stepping motor drives the compound cam 5 to rotate, so as to control the unlocking and locking processes of the lock plate.

As shown in fig. 8, 10 and 11, a first travel switch 31 and a second travel switch 32 are further disposed on the front surface of the substrate 1, the first travel switch 31 and the second travel switch 32 are both electrically connected to a controller of the stepping motor, and the controller of the stepping motor is used for controlling the operation of the stepping motor. The first travel switch 31 is positioned beside the lock tongue plate 2 and used for detecting the opening state of the lock tongue plate 2; the second stroke switch 32 is provided near the compound cam 5 and detects the stroke state of the sector 42 of the compound switch 5.

The anti-impact lock plate in the embodiment has the following unlocking process and locking process:

normally, as shown in fig. 8 and 11, the initial state of the tongue plate 2 is the off-lock state, and at this time, both the first travel switch 31 and the second travel switch 32 are in the on-state. Wherein the content of the first and second substances,

in the unlocking process, when the controller of the stepping motor 40 recognizes an external unlocking signal (code scanning or other input signal), as shown in fig. 10, the stepping motor 40 starts to rotate counterclockwise, the locking hook 4 of the compound cam first disengages from the connecting portion 20 of the locking push plate 3, as the compound cam rotates, the sector 42 of the compound cam pushes the connecting portion 20 of the locking push plate 3 to push open the locking push plate 3, the locking plate 2 rotates counterclockwise under the traction of the first extension spring 16 and the third extension spring 17 to open, the first travel switch 31 is triggered after the locking plate 2 opens, at this time, the first travel switch 31 is closed, the controller cannot detect the signal of the first travel switch 31, and then, the controller controls the stepping motor 40 to rotate clockwise, when the sector 42 of the compound cam 5 reaches the second travel switch 32, the second travel switch 32 is touched to open the second travel switch 32, the controller does not receive the signal of the second travel switch 32, which indicates that the tongue plate 2 is completely opened, and the controller controls the stepping motor to stop rotating, as shown in fig. 10, the tongue plate 2 keeps the open state, and the unlocking operation is finished. The tongue plate 2 which is opened at this time can be directly locked from the outside;

in the locking process, as shown in fig. 8, a user directly presses down the locking edge 11 of the tongue plate 2 by using the external lock lever 13, so that the tongue plate 2 rotates clockwise and downwards along the first wheel shaft 8 to be locked, the tongue plate 2 leaves the first travel switch 31, the first travel switch 31 is opened, a signal is given to the controller, the controller starts the stepping motor 40 to rotate clockwise after receiving the signal, in combination with that the tongue plate 2 rotates in the direction of the tongue plate 3 when being pressed down, the stepping motor 40 rotates clockwise to drive the lock hook 4 of the composite cam 5 to hook the connecting part 20 of the tongue plate 3, so that the limiting part 15 of the tongue plate 3 is clamped to the hook part 14 of the tongue plate 2 to lock the tongue plate 2, meanwhile, the fan-shaped part 42 of the composite cam 5 leaves the second travel switch 32, the second travel switch 32 is opened, and the controller receives the signal of the second travel switch 32 to control the stepping motor 40 to stop rotating, the locking plate completely enters a locking state, and the locking state is finished. The latching hook 10 of the bolt plate 2 now forms a ring-shaped latching structure 12 in a surrounding manner with the locking bar receiving recess 7 of the base plate 1, so that the locking bar 13 inserted in the latching structure 12 cannot leave the latching structure.

Since the second travel switch 32 is used for detecting the travel state of the sector 42 so as to judge the opening and closing state of the lock plate according to the travel state of the sector 42, when the sector 42 touches the second travel switch 32, the second travel switch 32 is turned off, which indicates that the lock plate is completely opened, when the lock plate is opened, the lock hook 4 on the compound cam is to be separated from the lock push plate 3, which is to limit the installation position of the second travel switch 32, so that the second travel switch 32 is located at a position such that the lock hook 4 is separated from the lock push plate 3 when the sector 42 touches the second travel switch 32.

When the lock plate is in a locking state, the lock hook 4 of the composite cam 5 keeps the connecting part 20 hooked on the lock push plate 3 to lock the lock push plate 3, and then the lock plate 2 is locked by the lock push plate 3, so that the lock plate 2 can be prevented from being opened when being impacted by external force on the side surface or being pushed by people with malicious use, the risk that the existing lock plate is pushed open by impact force in all directions and is pushed open by people intentionally or vehicles falling down can be effectively solved, and the safety of the lock plate is effectively improved.

In this embodiment, the first travel switch 31 and the second travel switch 32 form a dual-switch trigger signal, so that the controller knows the switch lock state, and further controls the stepper motor to drive the composite cam 5 to rotate to control the operation states of the sector 42 and the latch hook 4 on the composite cam 5, so as to control the position of the latch push plate 3 to control the locking state of the latch push plate 3 to the latch plate 2, and finally achieve the technical effect that the latch plate can be unlocked by an electronic signal, and after the latch plate is locked, the latch hook 4 on the composite cam 5 locks the latch push plate 3 for the second time, thereby achieving the dual-safety locking of the latch plate.

As shown in fig. 8 and 10, the same as the first embodiment, a protective plate 33 is also provided in the present embodiment, the protective plate 33 is fixed to the substrate 1 by the first rotating shaft 8 and the second rotating shaft 18, as shown in fig. 9, the protective plate 33 is parallel to the substrate 1, and the tongue plate 2 and the push plate 3 are located in the gap between the substrate 1 and the protective plate 33. When the first wheel axle 8 or the second wheel axle 18 is loosened due to corrosion, too low machining precision of parts and the like, the guard plate 33 can prevent the tongue plate 2 and the lock push plate 3 from being staggered to cause accidental unlocking of the lock plate. As shown in fig. 9, the edge of the guard plate 33 is provided with a first position-limiting post 38, and the first position-limiting post 38 can cooperate with the first position-limiting protrusion 36 to prevent the tongue plate 2 from over-rotating during the unlocking process. As shown in fig. 9, the lock pushing plate 3 is provided with a second limiting post 39 adapted to the second limiting protrusion 37, and the second limiting post 39 can be matched with the second limiting protrusion 37 to prevent the lock pushing plate 3 from over-rotating.
