[0020] In some embodiments, optionally, each of at least one of the lock buckles includes a first slope, which is located on the side of the groove facing the lock tongue, and the first slope is configured to contact the corresponding at least one mating portion and drive the lock tongue to move toward the second position during the locking process.

[0021] In some embodiments, optionally, each of at least one of the lock buckles includes a second sloped surface, which is arranged opposite to the groove, and the second sloped surface is configured to contact the corresponding at least one mating part and guide the corresponding at least one mating part to move in a direction away from the groove during the unlocking process.

[0022] In some embodiments, optionally, it further comprises a switch lock detection device connected to the controller, the switch lock detection device is arranged on the base, and the switch lock detection device is configured to contact with at least one of the lock buckles in a locked state and send lock information to the controller, and

[0023] After at least one of the lock buckles in contact with the switch lock detection device is separated from the switch lock detection device, the switch lock detection device sends a motor reset signal to the controller, so that the controller controls the motor to reset to an initial position.

[0024] In some embodiments, optionally, the controller has a timer, and the timer is configured to start timing after at least one of the lock buckles in contact with the switch lock detection device is separated from the switch lock detection device, so that the controller controls the motor to reset to the initial position after a preset time.

[0025] In some embodiments, optionally, the linkage mechanism includes a cam assembly, a rotating shaft of the cam assembly is connected to the output shaft of the motor; the movable end of the cam assembly is configured to contact the lock tongue and drive the lock tongue to move when the motor drives the cam assembly to rotate.

[0032] 2. The locking logic of the electric lock device is designed as follows: after unlocking, the lock tongue automatically resets to the locked position, and when locking, only the lock catch needs to be pushed toward the lock tongue to complete the locking. In a cabinet with a door, if other methods that require manual locking operations are used, such as issuing a locking command or manually operating a mechanical locking device, the operator forgets to perform the manual locking operation as described above due to negligence, which may cause the door to be closed with the cabinet but not actually locked, making it easy to be stolen.

[0033] 3. By setting up a switch lock detection device, the switch lock status can be detected after the lock is closed, and the unlocking method caused by abnormal reasons such as violent unlocking can also be detected. The electric control lock device of the present invention is used in combination with a remote communication device to monitor the switch lock status and abnormal unlocking status in real time. When the electric control lock device of the present invention is applied to a power exchange cabinet device, the switch lock status of the power exchange cabinet can be monitored in real time from the management background, which is conducive to reducing damage or theft of the power exchange cabinet, reducing operation and maintenance costs, and improving management efficiency.

[0045] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0046] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention in a schematic manner, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0047] While some exemplary embodiments of the present invention have been described for the purpose of illustration, it should be understood that the present invention may be implemented in other ways not specifically shown in the drawings.

[0048] like Figure 1As shown, a preferred embodiment of the present invention provides an electric lock device, including a lock body 100 and at least one lock catch matched with the lock body 100. When the electric lock device is in use, the lock body 100 is installed inside the locked object, and the lock catch is fixed on the door of the locked object and arranged opposite to the lock body 100. When the door is closed, the lock catch cooperates with the lock body 100 to complete the locking; when the lock catch is separated from the lock body 100, the lock on the door is released and the door can be opened. In this embodiment, the number of lock catches is set to two, namely the first lock catch 210 and the second lock catch 220. It should be understood that the number of lock catches can be set according to actual needs and is not limited to the two in this embodiment.

[0049] like Figure 1 As shown, the lock body 100 includes a base 110, a motor 130, a controller (not shown), a linkage mechanism 140, and a lock tongue 150. The base 110 is used as a bracket to mount other components on the base 110, and the lock body 100 is mounted in the locked object through the base 110. By designing the structure of the base 110, the lock body 100 can be integrated into a module for easy replacement and maintenance. In this embodiment, Figure 2 As shown, the base 110 includes a receiving cavity 111 (see Figure 3 ) and a working surface 112, the controller and the motor 130 are arranged in the accommodating chamber 111. The lock tongue 150 is arranged outside the accommodating chamber 111 and is arranged opposite to the working surface 112. A through hole 113 is arranged on the working surface 112, and the output shaft of the motor 130 passes through the through hole 113 and is connected with the linkage mechanism 140. The linkage mechanism 140 rotates under the drive of the motor 130, driving the lock tongue 150 to move. A mounting portion 114 is also provided on the base 110, which is used to install the base 110 in the locked object. The mounting portion 114 is an extension portion arranged on one side of the base 110. The mounting portion 114 is provided with mounting holes for fixing such as bolts and rivets. In this embodiment, the base 110 can be made by integral molding.

[0050] The controller is used to control the movement of the motor 130. The controller can communicate with the outside world, receive unlocking instructions, and control the movement of the motor 130 in response to the unlocking instructions. The controller can also send the switch lock status of the locked object to the outside world. At the same time, if the electric lock device is not unlocked by the controller in response to the unlocking instruction, but is unlocked abnormally or pried open due to external force, the controller can determine it as abnormal unlocking and report the abnormal unlocking situation to the background server.

[0051] The linkage mechanism 140 is connected to the motor 130. When driven by the motor 130, the linkage mechanism 140 rotates, thereby driving the lock tongue 150 to move. The lock tongue 150 is a component on the lock body 100 for cooperating with the first lock catch 210 and the second lock catch 220. The lock tongue 150 has a first position and a second position. Figure 4 As shown, when the lock tongue 150 is in the first position, the lock tongue 150 cooperates with the first lock buckle 210 and the second lock buckle 220, the electric control lock device is in a locked state, and the motor 130 is in the initial position. Figure 5 The unlocking process is shown. When the controller responds to the unlocking command, it controls the motor 130 to rotate counterclockwise. Driven by the linkage mechanism 140, the lock tongue 150 moves toward the second position, which is the direction indicated by a1 in the figure. After the lock tongue 150 is separated from the lock buckle, the first lock buckle 210 and the second lock buckle 220 move in the direction indicated by a2 under the action of an external force. The external force can be applied to the lock buckle when the user pulls the door of the locked object, or it can be applied to the lock buckle when the lock tongue 150 moves toward the second position. When the lock tongue 150 moves to the second position, it is completely separated from the first lock buckle 210 and the second lock buckle 220, and the electric control lock device is unlocked. Figure 6 As shown, after the unlocking is successful, the lock tongue 150 returns to the first position, and the motor 130 rotates clockwise to reset to the initial position. Figure 7 As shown, when the lock needs to be closed, it is only necessary to push the first lock buckle 210 and the second lock buckle 220 to the position of the lock tongue 150, that is, to move along the direction indicated by a4, so that the two lock buckles and the lock tongue 150 can be matched to complete the lock. With such a setting, the locking process does not need to be manually operated again, such as sending a lock command or manually mechanically locking, so that the false lock state caused by the user forgetting to operate can be avoided, that is, the door of the locked object is closed but not locked. It should be understood that the direction of movement of the motor 130 when unlocking and resetting is not limited to the counterclockwise direction or clockwise direction here. According to actual needs, its direction can be changed, or it can always move in a certain direction.

[0052] See also Figure 1, the lock tongue 150 is provided with a matching portion that matches with the lock buckle, and the number of the matching portions is consistent with the number of lock buckles. In the present embodiment, a first matching portion 151 that matches with the first lock buckle 210 and a second matching portion 152 that matches with the second lock buckle 220 are provided. The first matching portion 151 and the second matching portion 152 are both columnar structures. A first groove 211 that matches with the first matching portion 151 is provided on the first lock buckle 210, and a second groove 221 that matches with the second matching portion 152 is provided on the second lock buckle 220. When the two matching portions respectively fall into the corresponding two grooves, the two lock buckles and the lock tongue 150 complete the matching and thus lock; when the two matching portions are separated from the grooves, the lock buckle and the lock tongue 150 are separated and unlocked. As described above, in the unlocked state, the lock tongue 150 is located in the first position. As Figure 7 As shown, during the locking process, the two lock buckles move toward the lock tongue 150 (direction indicated by a4) under the action of external force. When the two lock buckles move to contact the lock tongue 150, the two lock buckles continue to move, thereby driving the lock tongue 150 to move toward the second position (direction indicated by a3). As the lock tongue 150 moves, when the two mating parts are aligned with the two corresponding grooves, the two mating parts fall into the corresponding grooves, thereby completing the locking.

[0053] The electric lock device of this embodiment further includes an elastic element 161. The function of the elastic element 161 is to exert an elastic force on the lock tongue 150 so that the lock tongue 150 moves from the second position to the first position. In this embodiment, the elastic element 161 is a spring, one end of the spring is connected to the lock tongue 150, and the other end of the spring is connected to the base 110. Figure 5 As shown, during the unlocking process, driven by the motor 130, the linkage mechanism 140 drives the lock tongue 150 to move, overcomes the elastic force of the elastic element 161, and moves the lock tongue 150 from the first position to the second position. Figure 6As shown, after unlocking is completed, the motor 130 is reset to the initial position, and accordingly, the linkage mechanism 140 also rotates, thereby separating from the lock tongue 150, and the force applied by the linkage structure on the lock tongue 150 to drive the lock tongue 150 to move toward the second position disappears. At this time, under the action of the elastic element 161, the lock tongue 150 returns from the second position to the first position. In the process of closing the lock, the lock buckle needs to overcome the elastic force of the elastic element 161 to make the lock tongue 150 move toward the second position. In this embodiment, two or more springs can be provided. It should be understood that other elastic elements 161 can also be used, such as spring pieces, torsion springs, rubber bands or other known elastic elements 161. It should also be understood that the return of the lock tongue 150 from the second position to the first position may also be achieved in other ways, not limited to the elastic element 161. For example, the lock tongue 150 may be driven by the motor 130 to return to the first position, and then the motor 130 is reset to the initial position. At this time, if the lock needs to be closed, the lock buckle is driven to move in the direction of the lock tongue 150, the lock buckle contacts the lock tongue 150 and drives the lock tongue 150 to move. When the lock tongue 150 is driven by the lock buckle to move until the mating part is aligned with the groove, the mating part of the lock tongue 150 is inserted into the groove of the lock buckle by relying on the gravity of the lock tongue 150, thereby completing the lock.

[0054] The structure of the lock buckle for cooperating with the lock tongue 150 is described in detail below. Since the structures of the two lock buckles for cooperating with the lock tongue 150 are the same, the first lock buckle 210 is used as an example for description. Fig. 9 As shown, in the locking process, in order to enable the first lock buckle 210 to smoothly complete the matching with the lock tongue 150, a first inclined surface 212 is further provided on the first lock buckle 210. The first inclined surface 212 is located on the side of the first groove 211 facing the lock tongue 150, and the end of the first inclined surface 212 close to the lock tongue 150 is lower than the end close to the first groove 211. When the lock buckle moves toward the lock tongue 150, the end of the first inclined surface 212 close to the lock tongue 150 first contacts the first matching portion 151 of the lock tongue 150. As the lock tongue 150 moves, the first matching portion 151 moves along the first inclined surface 212, so that the lock tongue 150 moves toward the second position. When the first matching portion 151 passes over the end of the first inclined surface 212 close to the first groove 211, the first matching portion 151 is aligned with the first groove 211 and falls into the first groove 211 under the action of the elastic element 161. In order to smoothly separate the first matching portion 151 from the first lock buckle 210 during the unlocking process, a second inclined surface 213 is further provided on the first lock buckle 210. The second inclined surface 213 is located above the first groove 211 and opposite to the first inclined surface 212. The end of the second inclined surface 213 close to the lock tongue 150 is higher than the end away from the lock tongue 150. Figure 5As shown, during the unlocking process, when the lock tongue 150 moves to the second position, the first matching portion 151 first contacts the end of the second inclined surface 213 away from the lock tongue 150. During the separation process, the first matching portion 151 moves along the second inclined surface 213 under the guidance of the second inclined surface 213, thereby driving the first lock buckle 210 to move in the direction away from the lock tongue 150. The second inclined surface 213 is provided so that the first matching portion 151 can be separated from the first lock buckle 210 more smoothly. The second lock buckle 220 has the same structure as the first lock buckle 210 for matching with the lock tongue 150, including a third inclined surface 222 similar to the first inclined surface 212 and a fourth inclined surface 223 similar to the second inclined surface 213, and its functions are also the same as the first inclined surface 212 and the second inclined surface 213, respectively, and will not be repeated here. It should be understood that any one of the first lock buckle 210 and the second lock buckle 220 having an inclined surface similar to the first inclined surface 212 and the second inclined surface 213 can also achieve the above functions without both lock buckles being provided with the inclined surfaces as described above.

[0055] The electric lock device of this embodiment also has a switch lock detection device 162. The switch lock detection device 162 is arranged on the base 110 and is connected to the controller. The switch lock detection device 162 cooperates with one of the two lock buckles to complete the detection of the switch lock state. Here, the cooperation between the switch lock detection device 162 and the first lock buckle 210 is taken as an example. In this embodiment, the switch lock detection device 162 is a touch switch, which is arranged opposite to the first lock buckle 210. More specifically, an extension portion 214 is provided on the first lock buckle 210. The extension portion 214 contacts and presses the switch lock detection device 162 in the locked state, and the switch lock detection device 162 is turned on and sends a locked state signal to the controller. Figure 6As shown, when the first lock buckle 210 is separated from the lock tongue 150, the switch lock detection device 162 is also separated from the extension portion 214, and the switch lock detection device 162 is disconnected and sends an unlocking state signal to the controller. When the switch lock detection device 162 is separated from the first lock buckle 210, that is, in the unlocking state, the switch lock detection device 162 also sends a motor 130 reset signal to the controller to control the motor 130 to reset to the initial position. Of course, in order to prevent the switch lock detection device from malfunctioning, the controller can also have a timer to realize an interrupt detection function: after the controller responds to the unlocking instruction to control the motor 130 to move and unlock, after the lock buckle is separated from the switch lock detection device 162, the timer starts timing, and the controller performs an interrupt detection. After the preset interrupt detection time has passed, regardless of whether the switch lock detection device 162 provides a motor 130 reset signal, the controller will still control the motor 130 to reset to the initial position. That is, if a system failure occurs, resulting in failure to unlock normally, the motor 130 will still reset, so that the lock tongue 150 will reset to the first position, so that the electric control lock device is still in the locked state; or, if a system failure occurs, although the unlocking is successful, but the switch lock detection device 162 does not send a reset signal for the motor 130, the motor 130 will still reset, and the lock tongue 150 will return to the first position under the action of elastic force, and when locking, only normal operation is required to complete the locking. This setting avoids the situation where the lock cannot be closed normally due to electrical failure.

[0056] See also Figure 1 and Figure 8 In this embodiment, the linkage mechanism 140 is a cam assembly. The rotating shaft of the cam assembly is fixedly connected to the output shaft of the motor 130. The cam assembly has a movable end for driving the lock tongue 150. Under the drive of the motor 130, the cam assembly rotates accordingly. During the rotation, the movable end contacts the lock tongue 150 and drives the lock tongue 150 to move. Under the action of the cam assembly, the rotation of the motor 130 is converted into the movement of the lock tongue 150. An active area 154 is provided on the lock tongue 150. The active area 154 is located in the middle of the lock tongue 150. The cam assembly is located in the active area 154. When the cam assembly drives the lock tongue 150 to move to the second position, the movable end of the cam assembly contacts the upper inner wall of the active area 154, thereby driving the lock tongue 150 to move. In this embodiment, the active area 154 is a rectangular opening provided on the lock tongue 150.

[0057] In some embodiments, the reduction motor 130 is selected, and in order to accurately determine the stroke of the motor 130, a first stroke switch 163 and a second stroke switch 164 connected to the controller are also provided. Figure 8As shown, the cam assembly includes a first movable end 141 and a second movable end 142, which are arranged opposite to each other and are respectively located on both sides of the cam rotating shaft 143. The first movable end 141 is used to drive the locking tongue 150 to move, and the second movable end 142 is used to trigger the travel switch. Figure 4 As shown, when the motor 130 is in the initial position, the second movable end 142 contacts the first travel switch 163, and when the motor 130 drives the lock tongue 150 to move to the second position, the second movable end 142 contacts the second travel switch 164. In the locked state, the motor 130 is in the initial position, the first travel switch 163 is in the on state, and the second travel switch 164 is in the off state. Figure 5 As shown, during the unlocking process, the second movable end 142 is first separated from the first travel switch 163, so that the first travel switch 163 is in the disconnected state, and at the same time, the first movable end 141 drives the lock tongue 150 to move; then when the lock tongue 150 moves to the second position, the second movable end 142 contacts the second travel switch 164, the second travel switch 164 is turned on, and the controller controls the motor 130 to stop moving. During the resetting process of the motor 130, the second movable end 142 is first separated from the second travel switch 164, so that the second travel switch 164 is disconnected, and then when the second movable end 142 moves to contact the first travel switch 163, the first travel switch 163 is turned on, the controller controls the motor 130 to stop moving, and the motor 130 is reset to the initial position (see Figure 6 ). Through the above settings, the motor 130 can be prevented from rotating past the defined position. In some embodiments, a stepper motor 130 or a servo motor 130 can be selected, and a travel switch can be omitted. In some embodiments, a motor with an encoder can be selected, and the motor travel can be controlled by detecting the rotation angle of the motor through the encoder.

[0058] In some embodiments, a stopper may be provided to prevent the motor 130 from rotating past a defined position. In this embodiment, two positioning posts, namely a first positioning post 115 and a second positioning post 116, are provided at the starting point and the end point of the movement stroke of the cam assembly, respectively. Both positioning posts are provided on the base 110, wherein the first positioning post 115 is located at the end point of the unlocking movement stroke of the cam assembly, and the second positioning post 116 is located at the end point of the resetting movement stroke of the cam assembly. In the unlocking process, if Figure 5 As shown, when the cam assembly moves to the first positioning column 115, it is blocked by the first positioning column 115; Figure 6 As shown, during the resetting process, the cam assembly moves to the second positioning column 116 and is blocked by the second positioning column 116. In this way, the rotation of the cam assembly can be limited, thereby preventing the motor 130 from rotating beyond the defined position.

[0059] See also Figure 1and Figure 2 In order to better limit the movement of the lock tongue 150 and better connect the lock tongue 150 with the base 110, a guide column 117 is provided on the working surface 112 of the base 110, and a guide groove 153 cooperating with the guide column 117 is provided on the lock tongue 150. The guide groove 153 is a narrow and long groove extending along the movement direction of the lock tongue 150. When the lock tongue 150 reciprocates between the second position and the first position, the guide column 117 moves in the guide groove 153. The cooperation between the guide column 117 and the guide groove 153 can better limit the linear movement of the lock tongue 150 without shaking. The number of the guide column 117 and the corresponding guide groove 153 can be set according to actual needs. In this embodiment, the number of the guide columns 117 is four, and the number of the guide grooves 153 is also set to four accordingly. Further, a blocking member 118 is provided at the top of the guide column 117 to limit the lock tongue 150 from shaking along the guide column 117 in the direction away from the base 110. After the guide post 117 is inserted into the guide groove 153, the blocking member 118 is installed at the top of the guide post 117, so as to prevent the lock tongue 150 from moving along the guide post 117 in a direction away from the base 110. At the same time, a blocking portion 119 is also provided at the bottom of the guide post 117, so as to prevent the lock tongue 150 from moving further along the guide post 117 in a direction close to the base 110 after the guide post 117 is inserted into the guide groove 153, so as to maintain a certain gap between the lock tongue 150 and the base 110, and reduce the obstruction of the base 110 to the movement of the lock tongue 150. The blocking portion 119 is provided on the outer circumference of the guide post 117, and is stepped with the guide post 117. The blocking portion 119 can be integrally formed with the guide post 117, or can be a blocking washer sleeved on the guide post 117. The dimensions of the blocking member 118 and the blocking portion 119 along the width direction of the guide groove 153 are both greater than the width of the guide groove 153, thereby effectively preventing the lock tongue 150 from shaking along the direction of the guide column 117. The guide column 117 can better keep the lock tongue 150 in a linear motion during the movement process, and will not shake in a direction perpendicular to the movement of the lock tongue 150, making the operation of the lock body 100 more stable and reliable.

[0060] The present invention also provides a cabinet, which uses the above-mentioned electric lock device. The lock body 100 is installed in the cabinet through the base 110, and the lock body 100 is modularly arranged, which is convenient for installation and replacement. The first lock buckle 210 and the second lock buckle 220 are fixed to the door of the cabinet by welding. When the first lock buckle 210 and the second lock buckle 220 are matched with the lock body 100, the door is closed and locked on the cabinet. When the first lock buckle 210 and the second lock buckle 220 are separated from the lock body 100, the door is opened to complete the unlocking. When it is necessary to lock, just push the door, when the first lock buckle and the second lock buckle 220 will drive the lock tongue 150 to move toward the second position, when the matching part of the lock tongue 150 is inserted into the groove of the lock buckle, the lock is closed. The switch lock detection device 162 sends the switch lock state information to the controller when it is disconnected or connected. A control panel is provided on the cabinet, and the controller can be electrically connected to the control panel, so as to send the switch lock status information to the control panel, and the control panel sends it to the background server. An alarm device can also be provided in the cabinet, and the alarm device can be selected as a buzzer. When the door of the cabinet is not opened by the controller in response to the unlocking instruction of the user terminal or the background server, but is abnormally opened or pried open due to external force, the controller determines that it is abnormal unlocking, and reports the illegal door opening to the server, and the buzzer in the cabinet starts to alarm.

[0061] In some embodiments, the cabinet is a cabinet of a power-swap cabinet, and the electric-controlled lock device is applied to the maintenance door of the power-swap cabinet. In order to achieve effective management of the power-swap cabinet, the power-swap cabinet is generally provided with a control panel with a remote communication function, and the controller of the electric-controlled lock device is electrically connected to the control panel, thereby achieving unified management and control of the maintenance door of the power-swap cabinet, and facilitating real-time monitoring of the switch lock status of the maintenance door of the power-swap cabinet by the background.
