Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Example 1: To address the problem that automatic coin locking mechanisms are prone to motor damage under impact, this invention provides an impact-resistant self-locking coin locking device, such as... Figure 1 As shown, the outer shell 1 of the coin liner is provided with a banknote inlet, and a sliding plate 2 is installed below the banknote inlet. The opening and closing of the banknote inlet is achieved by moving the sliding plate 2.

[0030] like Figure 2As shown, guide grooves are provided at both ends of the banknote inlet of the outer shell 1, and sliders are provided on both sides of the slide plate 2. The sliders are fitted into the guide grooves, so that the slide plate 2 moves along the guide grooves.

[0031] like Figures 3-6 As shown, a rack 9 is provided on the lower side of the slide plate 2, and the direction of the rack 9 is parallel to the direction of the guide groove. A motor for driving the slide plate 2 is also installed below the outer shell 1. Specifically, the motor is fixedly installed on the outer shell 1, and a cam 15 is fixed to the end of the motor shaft. A gear 14 is mounted on the motor shaft inside the cam 15, and a spring is mounted on the motor shaft inside the gear 14. A groove 151 is provided on the side of the cam 15 facing the gear 14, and a protrusion 141 is provided on the side of the gear 14 facing the cam 15. The protrusion 141 is fitted in the groove 151, and the width of the groove 151 is greater than the protrusion 141. The protrusion 141 has a certain amount of movement in the groove 151. A spring 2 is installed on the other side of the gear 14 to bring the gear 14 close to the cam 15.

[0032] Cam 15 is fixed to the motor shaft and rotates with the motor shaft. Gear 14 is movablely fitted with the motor shaft and does not rotate with the motor shaft. The motor drives cam 15 to rotate. The groove 151 of cam 15 engages with the protrusion 141 of gear 14, thereby driving gear 14 to rotate. Gear 14 meshes with rack 9 on slide plate 2, and then gear 14 drives slide plate 2 to move horizontally.

[0033] A locking component is installed opposite the cam 15. The locking component includes a fixing bracket 12 and a locking rod 13. The locking rod 13 is fitted onto the fixing bracket 12 and can extend and retract toward the cam 15. The cam 15 has a groove 152 on its side facing the locking rod 13. When the groove 152 rotates with the cam 15 to the position corresponding to the locking rod 13, the locking rod 13 can extend and retract and fit into the groove 152, thereby locking the cam 15.

[0034] like Figure 7 and Figure 8 As shown, the bottom of the groove 151 of the cam 15 has outward chamfers 153 on both sides, and the protrusion 141 of the gear 14 has corresponding chamfers 142 on both sides. The chamfers 153 and 142 do not fill their corresponding edges, so that the sides of the groove 151 and the protrusion 141 have locking platforms, so that the groove 151 and the chamfers 153 can be locked together, so that when the cam 15 rotates, it drives the gear 14 to rotate.

[0035] In reverse operation, gear 14 rotates actively, while cam 15 remains stationary due to the resistance of the motor. Gear 14 will slide due to friction under the relative action of chamfer 142 and bevel 153. Gear 14 compresses the spring and disengages from cam 15. At this time, cam 15 and gear 14 rub against each other and slip, allowing gear 14 to rotate independently.

[0036] A set of locking slots 10 are arranged on the slide plate 2, when the slide plate 2 slides to the open or closed limit position, one of the locking slots 10, the second groove 152 and the locking rod 13 correspond in a straight line, the locking rod 13 is inserted into the second groove 152 and the corresponding locking slot 10 at the same time, completing the locking of the motor and the slide plate 2.

[0037] A sensor is also installed on the money can shell 1, and a slide plate 2 detection strip 11 is arranged on the lower side of the slide plate 2, which is parallel to the rack 9. When the slide plate 2 moves, the detection strip 11 passes through the sensor, and a signal is sent by the sensor. The controller controls the operation and stop of the motor according to the signal sent by the sensor, and gives a signal of money can locking or opening.

[0038] Two parallel sensors are arranged, and the detection strip 11 corresponds to different sensors when opening and closing, so as to give different signals to the controller, so that the controller can easily judge the opening and closing of the slide plate 2.

[0039] An emergency unlocking device is installed opposite to the motor, which includes an emergency lock 3 and an emergency unlocking lever 7. The emergency unlocking lever 7 is installed between the lock and the emergency lock 3. A fixed shaft is arranged on the money can shell 1, and an axle hole is arranged in the middle of the lever. The lever is sleeved on the fixed shaft, the end of the lever towards the lock abuts against the locking rod 13, and the tail end of the emergency lock 3 is provided with an eccentric block. The end of the lever towards the emergency lock 3 abuts against the eccentric block. Rotating the emergency lock 3 can drive the eccentric block to rotate, and the eccentric block drives the lever to lift up, so that the locking rod 13 is lifted up and retracted, and the locking rod 13 is pulled out from the locking position, i.e. the second groove 152 and the locking slot 10, so as to realize the unlocking of the slide plate 2 and the motor. At this time, the slide plate 2 is manually pushed, the slide plate 2 pushes the gear 14, the gear 14 compresses the spring 2 and separates from the cam 15. At this time, the cam 15 and the gear 14 rub and slip, the slide plate 2 is opened, and the money can is opened.

[0040] Brief description of its working process:

[0041] Money can locking working process: the motor drives the cam 15 to rotate, and the gear 14 is driven to rotate through the cooperation of the concave points arranged on the cam 15 and the convex points 141 arranged on the gear 14. The gear 14 drives the slide plate 2 to move. When the slide plate 2 detection strip 11 of the slide plate 2 moves to the sensor on the controller, the detection strip 11 only blocks the sensor that sends the locking signal at this time, giving the controller a locking in place signal. The controller controls the motor to stop moving, and the lock enters the locking slot 10 on the slide plate 2 and the second groove 152 of the cam 15 at the same time. The detector is turned on, indicating that the lock is locked in place, and the money can is locked. If the money can is used abnormally and the impact force caused by violent throwing of the money can acts on the lock, the motor will not be damaged, which plays a protective role for the motor and prolongs the service life of the motor.

[0042] The money can opening process is as follows: the motor drives the cam 15, the inclined surface 154 of the groove arranged on the cam 15 pushes the lock piece out of the slide plate 2 lock groove 10, at the same time, the cam 15 drives the gear 14, the gear 14 drives the slide plate 2 rack 9 on the slide plate 2 to move reversely, when the slide plate 2 detection strip 11 on the slide plate 2 moves to the sensor, only the sensor sending the opening signal is blocked, at this time, the controller is given a signal to the open position, the motor stops running, at the same time, the lock piece enters the lock groove 10 of the slide plate 2 and the groove two 152 of the cam 15, the signal controller is turned on, the controller is given a signal to the open position, the slide plate 2 and the lock piece are both in the open position, and the money can opening process is completed.

[0043] Emergency unlocking function: when the money can slide plate 2 is locked and cannot be opened, the key is rotated to drive the emergency unlocking piece installed on the emergency lock 3 to rotate, the emergency unlocking piece pushes the emergency unlocking lever 7, the emergency unlocking lever 7 rotates to push the lock piece to move to the rear of the fixed frame 12, the lock piece is separated from the slide plate 2 lock groove 10 and the cam 15 groove, at this time, the slide plate 2 can be manually pushed, the slide plate 2 pushes the gear 14, the gear 14 compresses the spring and separates from the cam 15, at this time, the cam 15 and the gear 14 rub and slip, the slide plate 2 is opened, and the money can is opened.

[0044] Example 2: on the basis of example 1, the lock rod 13 is sleeved with a spring, the tail end of the lock rod 13 is provided with a push-pull device, the push-pull device and the spring are used to control the extension and contraction of the lock rod 13, wherein the push-pull device can be an electromagnet, for example, a columnar coil electromagnet, the lock rod 13 is made of magnetic material or the tail end of the lock rod 13 is additionally provided with magnetic material, the electromagnet is electrified to attract the lock rod 13, so that the lock rod 13 is retracted, the rotation of the cam 15 is avoided, when the electromagnet is de-energized, the spring pushes the lock rod 13 out, and the lock rod 13 is clamped in the groove two 152 of the cam 15 to lock the motor.

[0045] The motor and the electromagnet are synchronously controlled by the controller, when the motor starts, the electromagnet is synchronously turned on, the electromagnet attracts and retracts the lock rod 13, the cam 15 and the slide plate 2 can be driven to rotate or slide by the motor, when the motor stops, the electromagnet is synchronously turned off, the lock rod 13 is popped out under the action of the spring, and is clamped in the groove two 152 of the cam 15 and the corresponding lock groove 10 of the slide plate 2, so that the motor and the slide plate 2 are locked.

[0046] Compared with example 1, the active unlocking mode of the lock rod 13 is adopted in this example, the collision and friction between the lock rod 13 and the groove two 152 of the cam 15 are reduced, the locking and opening process is more smooth, and the problem that the money can is difficult to lock and open due to the deformation of the cam 15 and the lock rod 13 caused by long-term friction is avoided.

[0047] In the above embodiment, a torsion spring is installed on the emergency unlocking lever 7, and the torsion spring is used to keep the corresponding end of the emergency unlocking lever 7 always in contact with the lock rod 13. Specifically, as shown in Figs. 11 and 12, a sliding groove is arranged on the upper side of the fixed frame 12, the lock rod 13 protrudes upwardly in the sliding groove, the sliding block protrudes to the outside of the fixed frame 12, and the end of the lever is in contact with the protruding sliding block of the lock rod 13. The emergency unlocking lever 7 drives the lock rod 13 to retract by pushing the sliding block. Figure 3 and Figure 9 The end of the lever is in contact with the protruding sliding block of the lock rod 13. The emergency unlocking lever 7 drives the lock rod 13 to retract by pushing the sliding block.

[0048] A detector is further installed on the rear side of the lock, and the lock rod 13 correspondingly extends to touch the stop block of the detector. Whether the lock rod 13 is retracted to the position is determined by the stop block and the detector.

[0049] When the lock rod 13 is retracted to the position, the stop block blocks or touches the detector, and the detector sends a signal to the controller that the lock rod 13 is retracted. When the lock rod 13 is extended to lock, the stop block is separated from the detector and does not touch the detector, and the detector does not send a signal, indicating that the lock rod 13 is in the extended locking state.

[0050] In the above embodiment, a torsion spring is installed on the emergency unlocking lever 7, and the torsion spring is used to keep the corresponding end of the emergency unlocking lever 7 always in contact with the lock rod 13. Specifically, as shown in Figs. 11 and 12, a sliding groove is arranged on the upper side of the fixed frame 12, the lock rod 13 protrudes upwardly in the sliding groove, the sliding block protrudes to the outside of the fixed frame 12, and the end of the lever is in contact with the protruding sliding block of the lock rod 13. The emergency unlocking lever 7 drives the lock rod 13 to retract by pushing the sliding block.

[0051] When the lock rod 13 is retracted to the position, the stop block blocks or touches the detector, and the detector sends a signal to the controller that the lock rod 13 is retracted. When the lock rod 13 is extended to lock, the stop block is separated from the detector and does not touch the detector, and the detector does not send a signal, indicating that the lock rod 13 is in the extended locking state.
