In another embodiment, please refer to FIG. 2 and FIG. 3 together. FIG. 3 is a functional block diagram of a processing module according to an embodiment of the invention. As shown in FIG. 3, the processing module 19 has a processing unit 191, a wireless transmission unit 192, a memory unit 193, a first connection interface 194, and a second connection interface 195. The wireless transmission unit 192, the memory unit 193, and the first connection interface are provided. The 194 and the second connection interface 195 are electrically connected to the processing unit 191, and the first connection interface 194 is electrically connected to the sensing module 15 and the second connection interface 195 is used to electrically connect the braking module 17.

The first connection interface 194 and the second connection interface 195 are, for example, a general purpose input/output (GPIO), a serial general purpose input/output (SGPIO), or other suitable format. The connection interface is not limited in this embodiment. The sensing module 15 outputs the sensing signal to the processing unit 191 through the first connection interface 194, and the processing unit 191 outputs the trigger signal to the braking module 17 via the second connection interface 195.

The wireless transmission unit 192 uses, for example, WiFi, Bluetooth, or other suitable communication method. The wireless transmission unit 192 is configured to receive a control instruction, so that the processing unit 191 generates a trigger signal according to the control instruction. For example, the charging device 10 can be connected to the smart phone through the wireless transmission unit 192, and the user can control the charging device 10 through the smart phone. When the user sends a control command indicating that the charging device 10 does not move through the smart phone, the processing unit 191 generates a trigger signal according to the control command, so that the brake module 17 controls the roller 13 not to rotate. In other examples, the charging device 10 can be controlled by a central controller that causes the brake module 17 to control the roller 13 not to rotate by issuing a control command indicating that the charging device 10 is not moving.

In the above example, the central controller instructs the charging device 10 not to move, in more detail, the central controller controls the charging device 10 within the communication range by wireless communication methods such as WiFi, Bluetooth, or the like. When the sensing module 15 of the charging device 10 senses that it is being moved, the charging device 10 sends a message to the central controller to be moved. The central controller determines whether the current time when the charging device 10 is received by the charging device is within a preset time interval, and when the current time is within the preset time interval, the central controller generates a control instruction indicating that the charging device 10 does not move, so that The charging device 10 locks the roller 13. In a practical example, it is assumed that the preset time interval set in the central controller is 20:00 to 7:00, when the sensing module 15 of the charging device 10 senses that the charging device 10 is moved at 21:00. The processing unit 191 notifies the central controller of the moved message through the wireless transmission unit 192. The central controller determines that the current time of receiving the mobile message is 21:00, and determines that the current time 21:00 is within the preset time interval 20:00 to 7:00, the central controller generates a control command to the charging device 10 The charging device 10 is automatically locked to the roller 13.

In another embodiment, the control command received by the wireless transmission unit 192 of the charging device 10 is the current time sent by the central controller. Specifically, when the sensing module 15 of the charging device 10 senses that it is moved, the processing unit 191 of the charging device 10 receives the current time from the central controller and determines whether the current time is within the preset time interval. In still another specific embodiment, the control command received by the wireless transmission unit 192 of the charging device 10 is a preset time interval set in the central controller. When the sensing module 15 of the charging device 10 senses that it is moved, the processing unit 191 of the charging device 10 determines the current time by itself, and determines whether the current time is preset according to the preset time interval received from the central controller. Within the time interval.

In other words, the processing unit 191 of the charging device 10 generates a trigger signal according to the control command and the sensing signal. The user can set the time during which one or more sections of the charging device 10 may be normally moved and the time when the charging device 10 should not be moved by setting a preset time. When the charging device 10 senses that it is being moved, the charging device 10 selectively automatically locks the wheel 13 depending on whether or not the time when it is moved is within a time interval that should not be moved. For example, when the charging device 10 is placed in a school, the charging device 10 is normally moved for the school time at the school or the teacher's working time. When the charging device 10 is not moved during school hours or when the teacher is working, if the charging device 10 detects that it is being moved, the charging device 10 automatically locks the wheel 13 to reduce the chance of the charging device 10 being stolen.

In one embodiment, when the scroll wheel 13 of the charging device 10 is automatically locked, the processing unit 191 stores an automatic lock record in the memory unit 193. The auto-locking record includes, for example, the current time when the scroll wheel 13 is automatically locked, the distance the charging device 10 moves, the number of electronic devices placed inside the charging cabinet 11, or other suitable recorded content. In other embodiments, when the processing unit 191 determines that the current time is not within the preset time interval according to the sensing signal sent by the sensing module 15, the processing unit 191 can also store a movement record in the memory unit 193, and move the record. The current time when the charging device 10 is moved, the distance moved by the charging device 10, the number of electronic devices placed inside the charging cabinet 11, or other suitable recording contents may be included in the embodiment, which is not limited in this embodiment. When the processing unit 191 determines that the current time is not within the preset time interval according to the sensing signal sent by the sensing module 15, the processing unit 191 can also trigger other warning units to inform the user that the charging device 10 is moved.

As shown in FIG. 4, when four charging devices 20 are disposed in one indoor space, when the braking module of one of the charging devices 20 locks the roller, the processing unit of the charging device 20 that has locked the roller can be generated. The status signal is outputted to the central controller 30 through the wireless transmission unit, so that the central controller 30 generates a control command for controlling the other charging device 20 to lock the wheel according to the status signal, so that the other three charging devices are automatically locked together. Live the wheel.

In another embodiment, the central controller 30 issues a status reply request to the four charging devices 20, causing the charging device 20 to reply to the central controller 30 whether there is currently a locked roller. The central controller 30 then generates control commands for each of the charging devices 20 in accordance with the status of each of the charging devices 20. For example, when the central controller 30 determines that one of the charging devices 20 has locked the roller in the state in which the four charging devices 20 have replied, a control command is given to the other three charging devices 20 to make the rollers of the other three charging devices 20 Automatically locked.

In summary, the embodiment of the present invention provides a charging device that automatically locks a scroll wheel. The sensing module senses whether the charging device is moved and generates a sensing signal according to the sensing signal.
