[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In the present invention and the embodiments of the present invention, the filing cabinet may be a personnel filing cabinet.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides a filing cabinet. The filing cabinet includes: a base 1, a plurality of cabinets 3, a drive assembly, a positioning mechanism and a control device, wherein the base 1 includes a bottom plate 101 and at least one guide rail 2 provided on the bottom plate 101, and the guide rail 2 extends along a first direction; the plurality of cabinets 3 are arranged in sequence along the first direction, and the bottom of each cabinet 3 is provided with a slide groove 4 that can slide with the guide rail 2; the drive assembly is provided on one side of the plurality of cabinets 3, and the drive assembly includes a drive motor and a moving member 9 connected to the drive motor, and the moving member 9 can move relative to the base 1 along the first direction and selectively engage with the plurality of cabinets 3. A connection; a positioning mechanism is used to locate the position of the movable part 9; and a control device, including a controller and multiple control buttons 24, each cabinet 3 is provided with at least one control button 24, each control button 24 has at least two trigger states of moving out and returning to the position, multiple control buttons 24 are electrically connected to the controller, and the positioning mechanism is electrically connected to the controller; the controller receives the trigger signal emitted by the corresponding control button 24 and controls the action of the drive motor, and the drive motor drives the movable part 9 to move to the preset position and then drives the cabinet 3 corresponding to the control button 24 that emits the trigger signal to move in the corresponding direction.

[0027] In the above technical solution, two parallel guide rails 2 are provided on the base plate 101. When one of the multiple cabinets 3 needs to be moved, the control button 24 on the cabinet 3 is pressed or rotated to send a trigger signal to move the cabinet 3 in a certain direction (i.e., move out or return to its position). The control button 24 can transmit the trigger signal to the controller, and the controller controls the drive motor and the positioning mechanism to start at the same time. Under the drive of the drive motor, the moving part 9 can move along the first direction. When the moving part 9 moves to the cabinet 3 corresponding to the control button 24 that sends the trigger signal, the positioning mechanism can recognize the position of the moving part 9 and transmit the signal to the controller. The controller controls the drive motor to turn off, and the moving part 9 is connected to the cabinet 3 at the corresponding position and transmits the connection completion signal to the controller. The controller can control the drive motor to start, and the drive motor can drive the moving part 9 to move in the direction indicated by the trigger signal. In this way, driven by the drive motor, the moving part 9 can drive one or more cabinets 3 to move synchronously along the guide rail 2.

[0028] Through the above arrangement, the required cabinet 3 can be moved out or returned to its original position by simply operating the control button 24 without manual movement, thereby realizing the automated use of the filing cabinet and facilitating operation.

[0029] like Figure 3 and Figure 5 As shown, in an embodiment of the present invention, the moving part 9 is located below the cabinet 3, and the positioning mechanism includes an infrared receiver 11 and a plurality of infrared transmitters 22, wherein the infrared receiver 11 is arranged on the moving part 9; the plurality of infrared transmitters 22 correspond one-to-one to the plurality of cabinets 3 and are arranged at the bottom of the cabinet 3, and the signal emitted by each infrared transmitter 22 can be received by the infrared transmitter 22 to achieve positioning, and the infrared receiver 11 and the plurality of infrared transmitters 22 are electrically connected to the controller.

[0030] In the above technical solution, an avoidance groove 23 is provided under each cabinet 3, and the slide rail of the movable member 9 passes through the avoidance groove 23, thereby providing an avoidance space for the movable member 9 to move along the first direction.

[0031] Through the above-mentioned setting, after operating the control button 24 on a certain cabinet 3, the controller controls the corresponding infrared transmitter 22 to start powering on and emitting an infrared signal. In this way, when the movable part 9 moves to the bottom of the corresponding cabinet 3 (that is, the infrared receiver 11 is arranged opposite to the corresponding infrared transmitter), the infrared receiver 11 can receive the infrared signal emitted by the infrared transmitter 22, and the infrared receiver 11 transmits the signal to the controller. The controller can control the drive motor to stop running, so that the movable part 9 can be positioned under the cabinet 3 corresponding to the control button 24 that sends the trigger signal.

[0032] like Figures 1 to 3As shown, in an embodiment of the present invention, the filing cabinet also includes a connecting component for connecting the moving part 9 and the cabinet body 3, a card slot 10 is provided on the moving part 9, and a through hole corresponding to the card slot 10 is provided at the bottom of each cabinet body 3, and the connecting component includes a card block 18 and a lifting structure, wherein the card block 18 is movably connected to the cabinet body 3 and is movably arranged in the through hole; the lifting structure is electrically connected to the controller, and the lifting structure can drive the card block 18 to move up and down along the central axis of the through hole, so that the card block 18 has a mating position with the card slot 10 and a disengaged position with the card slot 10.

[0033] In the above technical solution, the infrared emitter 22 is arranged at the bottom of the card block 18 .

[0034] By the above arrangement, after the movable member 9 moves to the bottom of the cabinet 3, the controller controls the lifting structure to start. Under the drive of the lifting structure, the block 18 can move downward along the central axis of the through hole until a portion of the structure of the block 18 is located in the through hole and another portion of the structure of the block 18 is located in the slot 10. In this way, the movable member 9 and the cabinet 3 can be connected by the engagement of the block 18 and the slot 10. After the connection is completed, the controller controls the drive motor to start. Under the drive of the drive motor, the movable member 9 can drive the cabinet 3 to move synchronously according to the trigger signal sent by the control button 24, thereby moving the cabinet 3. When the movable member 9 does not need to be connected to the cabinet 3, the controller controls the lifting structure to start. Under the drive of the lifting structure, the block 18 can move upward along the central axis of the through hole until the block 18 is completely located in the through hole. This can avoid the block 18 from interfering with the movable member 9 and affecting the movement of the movable member 9.

[0035] like Figure 3 As shown, in an embodiment of the present invention, the lifting structure includes an electromagnet 19, a battery and a magnetic part 21, wherein the electromagnet 19 is connected to the block 18; the battery is connected to the electromagnet 19, and the battery is electrically connected to the controller; the magnetic part 21 is arranged on the cabinet 3, and the magnetic part 21 and the electromagnet 19 are spaced apart in the vertical direction.

[0036] In the above technical solution, the cabinet 3 is also provided with a mounting groove 14 connected to the through hole, and the lifting structure also includes a connecting member 16 located in the mounting groove 14, the connecting member 16 is connected to the block 18 and the connecting member 16 is movably connected to the top wall or bottom wall of the cabinet 3 through an elastic member 17, and an electromagnet 19 is installed on the connecting member 16, and there are two electromagnets 19, and the two electromagnets 19 are arranged on both sides of the block 18. In this way, under the expansion and contraction of the elastic member 17, the connecting member 16 can move up and down in the vertical direction, thereby driving the block 18 and the two electromagnets 19 to move synchronously; there are also two magnetic members 21, and the two magnetic members 21 are respectively arranged corresponding to the two electromagnets 19, and the two magnetic members 21 are fixed on the bottom wall of the mounting groove 14. In this way, the electromagnet 19 can attract each other with the magnetic member 21 after being electromagnetized. Since the magnetic member 21 is fixed on the bottom wall, the electromagnet 19 can move vertically downward until it is magnetically attached to the magnetic member 21, thereby driving the connecting member 16 and the block 18 to move downward synchronously and remain in this position.

[0037] Through the above-mentioned setting, when it is necessary to connect the cabinet 3 and the movable part 9, the controller controls the battery to supply power to the electromagnet 19. After being magnetized, the electromagnet 19 can move downward under the magnetic attraction of the magnetic part 21 and magnetically fit with the magnetic part 21. This can drive the connecting part 16 and the card block 18 to move downward synchronously and remain in this position. At this time, the card block 18 can be engaged with the card slot 10, thereby connecting the cabinet 3 and the movable part 9.

[0038] In another embodiment of the present invention, the magnetic member 21 may be installed on the connecting member 16 , and the electromagnet 19 may be fixed on the bottom wall of the installation groove 14 .

[0039] In another embodiment of the present invention, the electromagnet 19 can also be set at the bottom of the block 18, and the magnetic part 21 is set on the moving part 9; or, the magnetic part 21 is set at the bottom of the block 18, and the electromagnet 19 is set on the moving part 9.

[0040] In another embodiment of the present invention, the lifting structure may also be a linear motor or a hydraulic lifting rod.

[0041] like Figure 3 As shown, in an embodiment of the present invention, two mounting holes 20 connected to the mounting slot 14 are further provided on the bottom wall of the mounting slot 14. The mounting holes 20 extend in a vertical direction. The two mounting holes 20 correspond to the two electromagnets 19 respectively, and the two magnetic parts 21 are respectively installed in the two mounting holes 20.

[0042] In the above technical solution, the two magnetic parts 21 are respectively installed on the bottom walls of the two mounting holes 20. When the magnetic part 21 and the electromagnet 19 attract and fit each other, the electromagnet 19 is located in the mounting hole 20. In this way, the side wall of the mounting hole 20 can limit the electromagnet 19 and prevent the electromagnet 19 from moving in the horizontal direction, thereby ensuring that the electromagnet 19 and the magnetic part 21 always maintain magnetic fit.

[0043] In another embodiment of the present invention, the magnetic member 21 may also be fixed on the bottom wall of the mounting groove 14 .

[0044] like Figure 3 As shown, in an embodiment of the present invention, the lifting structure also includes two guide members 15 and two elastic members 17, wherein the two guide members 15 are located in the mounting groove 14 and are connected to the cabinet 3, the guide members 15 extend in the vertical direction, and the connecting member 16 is provided with two assembly holes corresponding to the guide members 15, and the two guide members 15 are located on both sides of the block 18; each elastic member 17 is sleeved on the outer periphery of a guide member 15, one end of the elastic member 17 is connected to the connecting member 16, and the other end of the elastic member 17 is connected to the top wall or bottom wall of the mounting groove 14.

[0045] In the above technical solution, one end of the elastic member 17 is connected to the connecting member 16, and the other end of the elastic member 17 is connected to the bottom wall of the mounting groove 14. In this way, on the one hand, the elastic member 17 can support the connecting member 16, and on the other hand, since the elastic member 17 is retractable, the connecting member 16 can move in the vertical direction; in addition, when the cabinet body 3 is connected to the movable member 9, the connecting member 16 moves downward and the elastic member 17 is in a compressed state. When the cabinet body 3 and the movable member 9 need to be separated, the controller controls the battery to stop supplying power to the electromagnet 19, and the magnetic attraction between the electromagnet 19 and the magnetic member 21 disappears. Under the elastic force of the elastic member 17, the connecting member 16 can drive the card block 18 to move upward synchronously to disengage the card block 18 from the card slot 10.

[0046] In another embodiment of the present invention, one end of the elastic member 17 is connected to the connecting member 16, and the other end of the elastic member 17 is connected to the top wall of the mounting groove 14. In this way, when the block 18 is engaged with the slot 10, the elastic member 17 is in a stretched state. When the cabinet 3 and the movable member 9 need to be separated, under the elastic force of the elastic member 17, the connecting member 16 can drive the block 18 to move upward synchronously, so that the block 18 is disengaged from the slot 10.

[0047] In an embodiment of the present invention, a contact position sensor electrically connected to the controller is provided within the card slot 10. Thus, when the card block 18 engages with the card slot 10, the card block 18 contacts the sensing end of the contact position sensor. The contact position sensor receives a signal indicating that the card block 18 is engaged and transmits the signal to the controller, which then controls the opening and closing of the drive motor.

[0048] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the driving motor is a rotating motor, and the driving assembly also includes a screw 8 that is driven and connected to the output shaft of the driving motor and extends along the first direction. The screw 8 is rotatably connected to the base 1, and a threaded hole that cooperates with the thread of the screw 8 is also provided on the moving part 9. Under the drive of the driving motor, the moving part 9 can move along the first direction.

[0049] In the above technical solution, the base 1 also includes a first side plate 5 and a second side plate 6 connected to the bottom plate 101 and arranged opposite to each other, and the driving assembly also includes two parallel slide rails 7, and the two ends of each slide rail 7 are respectively connected to the first side plate 5 and the second side plate 6. The bottom of the movable member 9 is provided with a groove that can slide with the slide rail 7. A screw 8 is provided between the two slide rails 7. The driving motor is fixed on the first side plate 5, and the output shaft of the driving motor is drivingly connected to one end of the screw 8. In this way, under the drive of the driving motor, the screw 8 can rotate around the central axis of the screw 8 relative to the base 1, thereby driving the movable member 9 to move along the length direction of the screw 8.

[0050] In another embodiment of the present invention, the drive motor may also be a linear motor, the fixed end of the linear motor is connected to the first side plate 5, and the telescopic end of the linear motor is directly connected to the moving member 9, thereby driving the moving member 9 to move along the first direction.

[0051] In an embodiment of the present invention, a proximity position sensor (i.e., a contactless sensor) is provided on the first side panel 5, and the proximity position sensor is electrically connected to the controller. Thus, when the movable member 9 drives the cabinet 3 to move within a preset distance of the proximity position sensor under the drive of the first drive motor 12, the proximity position sensor can identify a signal that the movable member 9 and the cabinet 3 have moved into place, and transmits the signal to the controller, which controls the first drive motor 12 to stop rotating. This can avoid the movable member 9 from colliding with the first side panel 5 and causing damage to parts. At this time, the movable member 9 has driven the cabinet 3 to move a certain distance, leaving enough operating space for the operator.

[0052] like Figure 1 As shown, in the embodiment of the present invention, the control button 24 is a push button, and each cabinet 3 is provided with two control buttons 24 , which respectively control the corresponding cabinet 3 to move out and return to its original position.

[0053] In the above technical solution, each cabinet 3 has a first button 241 and a second button 242. Pressing the first button 241 can transmit a trigger signal to the controller to return the cabinet 3 to its original position; pressing the second button 242 can transmit a trigger signal to the controller to move the cabinet 3 out.

[0054] In another embodiment of the present invention, the control button 24 may also be a knob, and by rotating the knob clockwise or counterclockwise, a trigger signal for moving out or returning to the original position may be transmitted to the controller.

[0055] like Figures 1 to 6 As shown, in an embodiment of the present invention, the filing cabinet includes two drive assemblies, which are spaced apart along a second direction forming an angle with the first direction, and the two drive assemblies respectively drive the cabinet body 3 to move out and return to its original position.

[0056] In the above technical solution, the two driving components are arranged parallel to each other, and an infrared receiver 11 is provided on each moving part 9. At the same time, two connecting components are provided on each cabinet 3, and an infrared transmitter 22 is provided at the bottom of each card block 18. Two through holes corresponding to the two card blocks 18 are opened on each cabinet 3, and the two card blocks 18 are spaced apart in the first direction and the second direction. In this way, when a connecting member 16 drives a card block 18 to move in the vertical direction, the other card block 18 is still located in the through hole, which can avoid interference between the other card block 18 and the moving part 9.

[0057] Through the above-mentioned setting, when the cabinet 3 needs to be moved out, the first drive motor 12 drives the corresponding moving part 9 to connect with the cabinet 3 and drives the cabinet 3 to move synchronously; when the cabinet 3 needs to be returned to its place, the second drive motor 13 drives the corresponding moving part 9 to connect with the cabinet 3 and drives the cabinet 3 to move synchronously.

[0058] like Figure 1 As shown, in an embodiment of the present invention, each cabinet 3 is further provided with an information bar 25, which is electrically connected to the controller. The information bar 25 is used to display the operating status of the cabinet 3 in which it is located. For example, when the operator needs to move out a cabinet 3, he presses the second button 242 on the cabinet 3, and the controller controls the information bar 25 on the cabinet 3 to display the operating status as "move out".

[0059] The following describes the method for using the filing cabinet according to an embodiment of the present invention:

[0060] like Figures 1 to 6 As shown, when a cabinet 3 needs to be moved out (for example, Figure 1The cabinet 3 is located in the middle), and the second button 242 on the cabinet 3 is pressed. The second button 242 can transmit the signal of moving out of the cabinet 3 to the controller. The controller controls the first drive motor 12 to start, and controls the infrared transmitter 22 provided on the cabinet 3 to be energized and emit an infrared signal. Driven by the first drive motor 12, the screw 8 rotates and drives the movable member 9 to move along the first direction. When the movable member 9 moves to the bottom of the middle cabinet 3, the infrared receiver 11 can receive the infrared signal emitted by the infrared transmitter 22 and determine that the movable member 9 has moved into place. The infrared receiver 11 transmits the signal to the controller; the controller controls the first drive motor 12 to stop running, and controls the battery to power the electromagnet 19. After being magnetized, the electromagnet 19 can be attracted by the magnetic member 21. Under the action of magnetic attraction, the electromagnet 19 can move downward until it is magnetically fitted with the magnetic member 21. The electromagnet 19 can drive the connecting member 16 and the block 18 to move synchronously. In this way, The card block 18 can be engaged with the card slot 10 of the movable part 9. The contact position sensor transmits a signal to the controller after recognizing that the card block 18 has been engaged with the card slot 10. The controller controls the first drive motor 12 to start. Driven by the first drive motor 12, the movable part 9 can drive the middle cabinet 3 and the two cabinets 3 located on the right side of the middle cabinet 3 to move synchronously to the right. When it moves to the rightmost end, the proximity position sensor recognizes the position of the movable part 9 and the cabinet 3 and transmits the position signal to the controller. The controller controls the first drive motor 12 to stop running, and the controller controls the battery to stop supplying power to the electromagnet 19. The magnetic attraction between the electromagnet 19 and the magnetic part 21 disappears. Under the elastic action of the elastic part 17, the connecting part 16 can drive the card block 18 to move upward, and the card block 18 disengages from the card slot 10 to separate the cabinet 3 from the movable part 9, so that the middle cabinet 3 can be moved out, and the user can store and retrieve archival documents.

[0061] When all cabinets 3 need to be returned to their original positions, press the first button 241 on the rightmost cabinet 3. The first button 241 will transmit the signal of moving out of the cabinet 3 to the controller. The controller controls the second drive motor 13 to start and controls the infrared emitter 22 set on the cabinet 3 to start. The subsequent working process is the same as the above-mentioned working process of moving out of the cabinet 3, and will not be repeated here.

[0062] When returning the middle cabinet 3 to its original position, it is only necessary to press the first button 241 on the middle cabinet 3 .

[0063] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when it is necessary to move one of the multiple cabinets, press the control button on the cabinet to send a trigger signal to move the cabinet in a certain direction (i.e., move out or return), and the control button can transmit the trigger signal to the controller, and the controller controls the drive motor and the infrared transmitter to start at the same time. Under the drive of the drive motor, the moving part can move in the first direction. When the moving part moves to the cabinet corresponding to the control button that sends the trigger signal, the infrared receiver can receive the infrared signal sent by the infrared transmitter and transmit the signal to the controller, and the controller controls the drive motor and the infrared transmitter to start at the same time. The motor is turned off, and the control battery supplies power to the electromagnet. Under the action of magnetic attraction, the electromagnet moves toward the magnetic part, that is, the electromagnet can drive the connecting part and the card block to move vertically downward. The card block engages with the card slot and transmits the connection completion signal to the controller. The controller can control the drive motor to start, and the drive motor can drive the moving part to move in the direction indicated by the trigger signal. In this way, driven by the drive motor, the moving part can drive one or more cabinets to move synchronously, and the cabinet can move along the guide rail. Only the control button needs to be operated to move out or return the required cabinet. No manual movement is required, which can realize the automated use of the filing cabinet and is easy to operate.
