Only the staff or the manager of the data acquisition body 20 can use and manage the automatic driving device 40 of the corresponding law enforcement recorder 10, the situation that the staff take the law enforcement recorder 10 by mistake or the law enforcement recorder 10 is stolen is prevented, the structure is simple, and the anti-theft effect is good. When it is desired to remove law enforcement recorder 10, automatic drive device 40 automatically drives locking assembly 30 back to the side of data collection body 20 opposite slot 21, and flap 11 is opened, so that law enforcement recorder 10 can be easily removed. In consideration of the sudden occurrence of a failure of the automatic driving device 40, such as a crash of the control system, a sudden power failure, and the like, which causes the law enforcement recorder 10 to be locked and cannot be opened, and further causes a policeman to be unable to go out for patrol duty, the data acquisition device provided in this embodiment further includes a manual driving device 50, the manual driving device 50 manually drives the locking assembly 30 to return to open the blocking piece 11, so as to ensure the sudden failure of the automatic driving device 40, and a worker can manually open the blocking piece 11 and take out the law enforcement recorder 10.
As a preferred aspect of the present invention, the locking assembly 30 includes a cam 31, a locking piece 32 elastically connected between the data collecting body 20 and the cam 31; the automatic driving device 40 includes a motor 41, the motor 41 rotates to drive the cam 31 to rotate, and the locking barrier 32 is driven to linearly penetrate through the data acquisition body 20 and clamp the barrier 11 to lock the barrier 11 or leave the data acquisition body 20 to open the barrier 11.
In this embodiment, as shown in fig. 4(a) to 4(b), the motor 41 provides power to drive the cam 31 to rotate, and the cam 31 and the lock catch 32 are similar to the principle of a cam follower mechanism, that is, when the motor 41 rotates to drive the cam 31 to rotate continuously in one direction, the surface of the cam 31 starts to contact the plane of the lock catch 32, and the highest point and the lowest point of the cam 31 respectively and alternately collide with the plane of the lock catch 32, so as to realize the forward and backward movement of the lock catch 32, thereby converting the circular motion of the cam 31 into the linear reciprocating motion of the lock catch 32. The straight reciprocating motion of lock separation blade 32 specifically means that lock separation blade 32 straight line runs through data acquisition body 20 joint separation blade 11 with locking separation blade 11, blocks law enforcement record appearance 10 and is taken out, or leaves in order to open separation blade 11, does benefit to the taking out of law enforcement record appearance 10, consequently, through separation blade 11, motor 41, cam 31 and the linkage cooperation of lock separation blade 32, the realization is pinned and is opened the action behind the slot 21 of pegging graft on data acquisition body 20 with law enforcement record appearance 10. The cam 31 and the lock catch sheet 32 are in point-line contact all the time, so that abrasion between the two parts is bound to occur, the cam 31 and the lock catch sheet 32 are preferably made of POM materials with self-sliding effect, the POM materials are high in impact strength and excellent in wear resistance and self-lubricating property, and the service lives of the cam 31 and the lock catch sheet 32 are prolonged.
As a preferred aspect of the present invention, the manual driving device 50 includes: a latch 51 located on the data acquisition body 20; and, a linkage for linkage between the tongue lock 51 and the cam 31; the latch post 511 of the latch 51 rotates to drive the cam 31 to slide in a linked manner, and drives the lock catch 32 to return to open the catch 11. In this embodiment, the operator inserts the key into the tongue lock 51 of the manual driving device 50 to rotate the tongue lock cylinder 511, because of the linkage device, the rotation of the tongue lock cylinder 511 drives the cam 31 to link, more precisely, the rotation of the tongue lock cylinder 511 drives the cam 31 to slide in a linkage manner, so that the cam 31 slides to make the highest point leave the abutting lock catch 32, and then the lock catch 32 loses the abutting and returns elastically to open the catch 11. Thus, the locked enforcement recorder 10 can be manually unlocked by the staff in the event of a failure of the automatic drive 40, simply by keeping a key that matches the tongue lock 511.
As a further preferred aspect of the above embodiment, the linkage includes: the first linkage device 52 comprises a first spring 521 sleeved on the shaft of the motor 41, a nut 522 penetrating through the cam 31 and connected to the tail end of the shaft of the motor 41 in a threaded manner, and a hollow sleeve 523 sleeved outside the nut 522; and a second linkage 53 including a guide rail groove 531 axially parallel to the motor 41, a first link 532 and a second link 533 which slide in cooperation with the guide rail groove 531; wherein the tongue lock cylinder penetrates one end of the first link 532; the second link 533 is fixed vertically between the first link 532 and the sleeve 523; the rotation of the latch column 511 drives the first link 532 to slide along the guide track groove 531, which drives the sleeve 523 and the cam 31 to slide in linkage, and drives the latch stop 32 to return elastically to open the stop 11.
In the above embodiment, the latch column 511 penetrates one end of the first link 532 through the kidney-shaped hole; the second link 533 is fixed vertically between the first link 532 and the sleeve 523; causing linkage between the sleeve 523 and the first link 532. The worker inserts the key into the tongue lock 51 in a matching manner to rotate the tongue lock cylinder 541, and drives the first link 532 to move up and down in the guide rail groove 531 along the length direction of the first link 532; thereby driving the sleeve 523 fixedly connected with the second connecting rod 533 through the screw to link in the same direction. The sleeve 523 is linked to drive the cam 31 to slide, so that the highest point of the cam 31 is separated from the abutting lock catch 32, and the lock catch 32 loses the abutting and elastically returns to open the catch 11. More specifically, as shown in fig. 5, when the law enforcement recorder 10 is not plugged in the data acquisition body 20, the cam 31 is in the initial position set by the control system under the action of the elastic force of the first spring 521; the lock catch 32 is also in the initial position set by the control system. After the law enforcement recorder 10 is inserted into the slot 21 of the data acquisition body 20, the motor 41 of the automatic driving device 40 drives the locking assembly 30 to lock the law enforcement recorder 10, and at this time, the highest point of the cam 31 abuts against the plane of the lock catch 32, and the lock catch 32 abuts against and penetrates through the data acquisition body 20. If the law enforcement recorder 10 suddenly encounters an emergency situation such as power failure of the data acquisition body 20 or crash of a control system under the state of charging after locking or uploading data to the data acquisition body 20, a manager of the data acquisition body 20 has the highest authority, and can use a key to match with the plug-in tongue lock 51 and rotate the tongue lock cylinder 541 according to clockwise change of the position of the tongue lock cylinder 541 shown in fig. 6 to 7, so as to drive the first link 532 to move linearly upwards in the guide rail groove 531 along the length direction thereof, and drive the sleeve 523 and the cam 31 to slide in a linkage manner in the same direction. The nut 522 is always kept still, the sleeve 523 and the cam 31 are linked in the same direction to slide to push the first spring 521 to be compressed, and the highest point of the cam 31 is forced to be away from the plane of the unlocking catch 32; and the lock catch 32 is elastically connected between the cam 31 and the data acquisition body 20, so that the lock catch 32 can elastically return after losing the highest point of the cam 31 to enable the catch 11 to be opened, and the law enforcement recorder 10 can be easily taken out. Through the linkage device provided in the embodiment, a worker can insert the tongue lock 51 corresponding to the slot 21 through key matching and rotate the tongue lock cylinder 541 clockwise, so as to drive the first connecting rod 532, the sleeve 523 and the cam 31 to slide in a linkage manner, so as to manually open the anti-theft structure of the law enforcement recorder 10 and take out the law enforcement recorder 10, thereby effectively avoiding the problem that the law enforcement recorder 10 cannot be taken out or the law enforcement recorder 10 cannot be locked to the data acquisition body 20 when a policeman is preparing to go out for duty under the conditions of sudden outage or control system crash and the like. The manager of the data acquisition body 20 manages keys matched with the tongue locks 51 in a unified manner, which is beneficial to unified management. It should be noted that after clockwise rotation of the latch post 541 opens the flap 11 and the law enforcement recorder 10 is removed, the latch 54 and thus the lock assembly 30 must be reset by counterclockwise rotation of the latch post 541. Because the control system of the data acquisition device detects whether the locking assembly 30 returns after the power is supplied or the data acquisition device works normally, if the locking assembly 30 returns, all the data acquisition device is normal, if the locking assembly 30 returns, the alarm is given, and meanwhile, the automatic driving device 40 does not work any more until the control system detects that the locking assembly 30 returns.
As a further preferable mode of the above embodiment, the linkage further includes a link guide 54, and the link guide 54 includes: a guide post 541, a vertical guide rail groove of which is disposed on the data acquisition body 20; a first through hole 542 located on the first link 532; the guide post 541 is matched and penetrates through the first through hole 542; the sliding of the first link 532 drives the guide post 541 to slide in the first through hole 542. In this embodiment, guide post 541 fits through first through hole 542; the sliding of the first link 532 drives the guide post 541 to slide in the first through hole 542, so as to provide guidance and limitation for the sliding of the first link 532 along the length direction and the sliding amplitude thereof. The length of the first through hole 542 depends on the sliding stroke of the first link 532. As a further preference, the link guides 54 are provided in groups spaced apart on the first link 532. The number of sets of link guides 54 depends on the length of the first link 532, and the present embodiment preferably has three sets of link guides 54 spaced apart on the first link 532.

The second spring 333 provides a spring force that urges the return of the lock shutter 32 after passing through the second through-hole 22 to clear the second through-hole 22 and open the shutter 11. The latch spring 334 is locked in a groove of the guide pin 332 to prevent the second spring 333 from ejecting the latch plate 32, and to limit the stroke and position of the reciprocating movement of the latch plate 32. When the law enforcement recorder 10 is inserted into the slot 21 of the data acquisition body 20, the control system of the data acquisition body 20 automatically detects that the law enforcement recorder 10 sends an instruction to the motor 41, the motor 41 starts to rotate according to the angle set by the control system to drive the cam 31 fixedly connected with the motor to rotate by the same angle, when the highest point of the cam 31 rotates to the angle set by the control system, the cam 31 abuts against the lock blocking piece 32, meanwhile, the second spring 333 below the lock blocking piece 32 is compressed, the lock blocking piece 32 moves linearly along the axial direction of the guide pin 332, the lock blocking piece 32 abuts against and penetrates through the second through hole 22 to block the blocking piece 11 of the law enforcement recorder 10, and at this time, the law enforcement recorder 10 cannot be taken out and locked. When the law enforcement recorder 10 is inserted into the slot 21, the control system displays the detected information on the touch screen arranged on the right side of the data acquisition body 20, the on-off state of the law enforcement recorder 10 in the slot 21 is displayed on the touch screen, when the law enforcement recorder 10 is inserted into the slot 21, the current slot 21 is displayed to be locked, and when the law enforcement recorder 10 is not inserted into the slot 21, the current slot 21 is displayed to be opened by the slot 21. When the control system detects that the law enforcement recorder 10 exists, the control system can automatically charge the law enforcement recorder 10, and automatically upload the relevant data on the law enforcement recorder 10 to a hard disk of the data acquisition body 20 for storage. When the law enforcement recorder 10 needs to be taken out, the system sends an instruction to the motor 41 after the touch screen is clicked to unlock and scans the fingerprint of the system, the motor 41 starts to rotate according to the preset angle of the system, the cam 31 is driven to rotate by the same angle, when the lowest point of the cam 31 rotates to the angle set by the control system, the lock catch 32 pushes the lock catch 32 downwards under the elastic force of the second spring 333 to return to the initial position, due to the existence of the snap spring 334, the lock catch 32 cannot be popped up by the second spring 333, at this moment, the second through hole 22 is not blocked by the lock catch 32, and the law enforcement recorder 10 can be taken out. Through the touch screen, the working personnel can independently use and manage the law enforcement recorder 10 of the individual, and can use and manage the law enforcement recorder 10 of other people without authority, thereby preventing the phenomenon that the law enforcement recorder 10 is stolen by mistake or under other conditions. Meanwhile, a high-level administrator of a control system of the data acquisition body 20 has the highest authority, can perform centralized management on the plug-in locking, charging and data transmission of all the law enforcement recorders 10 on one data acquisition body 20, and has a better unified management level.
As a preference of the above embodiment, the lock catch connecting means 33 are two sets symmetrically disposed on both sides of one lock catch 32; correspondingly, as shown in fig. 3, the lock catch 32 has a third through hole 321 through which the two guide pins 332 of the two lock catch connecting devices 33 pass, and the lower end of the lock catch 32 is inserted into the second through hole 22 in a matching manner. Two lock catch sheet connecting devices 33 arranged at two sides of one lock catch sheet 32 improve the balance of the linear reciprocating motion of the lock catch sheet 32 driven by the rotation of the cam 31.
