According to a preferred embodiment of the present invention, the smart lock anti-pry apparatus 10 further includes a guide post 16 and a second spring 17. The main circuit board 12 is provided with a through hole, and the guide post 16 is inserted into the through hole, so as to guide the main circuit board 12 to move up and down along the guide post 16. In order to prevent the main circuit board 12 from being detached from the guide post 16, a stopper (a portion of the upper end of the guide post 16 in the drawing) is provided at one end of the guide post 16, and the size or diameter of the stopper may be larger than the diameter of the guide post 16, so that the main circuit board 12 cannot be detached from the guide post 16.

The mounting block 18 preferably has a mounting hole having a diameter substantially the same as the outer diameter of the probe 14, and a first spring 15 is located in the mounting hole and below the probe 14 so that the probe 14 can slide up and down in the mounting hole. Preferably, a plurality of mounting seats 18 are arranged on the main circuit board 12, and each mounting seat 18 is provided with one probe 14 and one first spring 15.

By providing an appropriate first spring 15 and/or depth of the mounting hole in the mounting block 18, the range of travel of the probe 14 relative to the main circuit board 12 can be set. Preferably, the probe 14 has a range of travel between 3-5mm relative to the main circuit board 12. By providing an appropriate second spring 17, the range of travel of the main circuit board 12 relative to the housing 11 can be set.

Further in accordance with a preferred embodiment of the present invention, the elastic constant of the first spring 15 is smaller than the elastic constant of the second spring 17. Therefore, when the anti-prying circuit board 13 is pressed downwards and applies pressure to the probe 14, the compression degree of the first spring 15 is greater than that of the second spring 17, and the main circuit board 12 is subjected to strong upward extrusion force, so that the electric connection between the anti-prying circuit board 13 and the probe 14 is promoted, and the movement stroke of the intelligent lock anti-prying device 10 is increased. The spring constant of the second spring 17 is preferably twice the spring constant of the first spring 15.

According to a preferred embodiment of the present invention, the main circuit board 12 is electrically connected to the probe 14, and the anti-prying circuit board 13 is provided with a gold-plated contact at a position contacting the probe 14, and the gold-plated contact is electrically connected to the anti-prying circuit board (e.g., a circuit loop thereon). In the embodiment, the scheme that the probe is in contact with the gold-plated circuit board is adopted, so that the conductivity can be ensured, and the service life is prolonged; the spring is adopted, so that the movement stroke of the anti-prying system can be increased, and the mistaken touch and the mistaken alarm caused by smaller stroke can be prevented.

The smart lock anti-pry apparatus 10 according to the preferred embodiment of the present invention is described in detail above with reference to fig. 1, and the operation principle and operation of the smart lock anti-pry apparatus 10 will be described in detail below with reference to fig. 2a, 2b, 2c and 2 d. Where fig. 2a illustrates smart lock anti-pry apparatus 10 in a normal state and fig. 2b, 2c, and 2d illustrate, respectively, the changing states of smart lock anti-pry apparatus 10 when pryed by an external force.

As shown in fig. 2a, in a normal state, the upper half case and the lower half case of the housing 11 are in a closest state, the anti-prying circuit board 13 is in a lowermost position, and contacts and establishes electrical connection with the probes 14, and the anti-prying circuit board 13 applies a downward pressing force to the probes 14, so that the first springs 15 are greatly compressed, and at the same time, applies a downward pressing force to the main circuit board 12, so that the second springs 17 are compressed downward. At this time, the anti-prying circuit board 13 is electrically connected with the probe 14, so that a circuit loop on the anti-prying circuit board 13 is closed, and an alarm connected externally does not give an alarm.

When the smart lock anti-pry apparatus 10 is pried to some extent, as shown in fig. 2b, the upper housing half of the housing 11 is moved slightly upward, the anti-pry circuit board 13 is also moved upward, the probe 14 is extended upward by the first spring 15, and the main circuit board 12 is also moved upward along the guide post 16 by the second spring 17. The amount of compression of both the first spring 15 and the second spring 17 is somewhat released in fig. 2b compared to the normal state of fig. 2 a. In the state of fig. 2b, since the upward movement amount of the anti-pry circuit board 13 is not large (e.g., 3-5mm), the anti-pry circuit board 13 and the probe 14 are still electrically connected, so that the circuit loop on the anti-pry circuit board 13 is closed and the alarm connected externally does not give an alarm.

When the smart lock anti-pry apparatus 10 is further pried, as shown in fig. 2c, the upper housing half of the housing 11 is moved further upward, the anti-pry circuit board 13 is also moved upward, the probe 14 continues to extend upward under the action of the first spring 15, and the main circuit board 12 is also moved upward along the guide post 16 under the action of the second spring 17. The amount of compression of the first spring 15 and the second spring 17 is further released in fig. 2c compared to the normal state of fig. 2 b. In the state of fig. 2c, since the anti-pry circuit board 13 does not move upward by a large amount (e.g., 3-5mm further upward than the state of fig. 2 b), the anti-pry circuit board 13 and the probe 14 remain electrically connected, so that the circuit loop on the anti-pry circuit board 13 is closed and the externally connected alarm does not give an alarm. At this time, the first spring 15 and the second spring 17 release their compression completely, the probe 14 cannot move further upward, the smart lock anti-pry apparatus 10 is in a critical state, and when the upper half of the housing 11 moves further upward, the anti-pry circuit board 13 will be separated from the probe 14.

As shown in fig. 2d, when the smart lock anti-prying apparatus 10 is further pried, the upper half of the housing 11 moves further upward, the anti-prying circuit board 13 also moves upward, and the probe 14 cannot extend upward because the first spring 15 and the second spring 17 have completely released their compression amounts and cannot rebound, so that the anti-prying circuit board 13 is electrically disconnected from the probe 14, the circuit loop on the anti-prying circuit board 13 is disconnected, and the alarm connected externally will give an alarm.

The structure and operation of the smart lock anti-pry apparatus 10 according to the present invention are described above. The intelligent lock anti-pry device 10 can be combined with an external alarm, the alarm is in signal connection with the intelligent lock anti-pry device 10, and an alarm can be given out according to the separation of the probe 14 in the intelligent lock anti-pry device 10 and the anti-pry circuit board 13.

According to a preferred embodiment of the present invention, a circuit detection device may be disposed in the alarm, for detecting the opening and closing of the circuit loop on the anti-picking circuit board of the intelligent lock anti-picking apparatus 10, and when the circuit loop is opened (as shown in fig. 2 d), the alarm is triggered to emit an audible, optical, and electrical alarm; when the circuit loop is closed (as in the state shown in fig. 2a, 2b or 2 c), the alarm is prevented from issuing an alarm.

Fig. 3 shows an alarm 20 according to a preferred embodiment of the utility model, described in detail below with reference to fig. 3.

The light sensor 23 is arranged in the closed space, when the light emitter 22 is started, the light sensor 23 sends out an alarm signal, and when the light emitter 22 is closed, the light sensor 23 does not send out a signal. Specifically, as shown in fig. 3, when the anti-prying circuit board 13 is separated from the probe 14, the light emitter 22 is activated and emits a light beam L, which is reflected on the inner wall of the housing 21, and a part of the reflected light beam L' is incident on the photosensor 23. The light-sensitive sensor 23 comprises a photo-sensor that converts said reflected light beam L' into an electrical signal (i.e. an alarm signal) that, after further amplification, can be used to trigger or drive a light-emitting or sound-emitting unit to emit an alarm.

According to a preferred embodiment of the present invention, the light emitter 22 and the photosensitive sensor 23 are disposed on a circuit board 24, and the light emitter 22 is electrically connected to the anti-pry circuit board 13 of the smart lock anti-pry apparatus 10.
