[0002] Currently, a compact shelf is a storage device used to store a large number of documents, materials or files. Its unique structural design enables efficient utilization of storage space. Specifically, through the mobile setting of the chassis, a single rack body of the compact shelf can move flexibly on the rails laid on the ground, so as to realize the close arrangement or convenient separation of the rack bodies to meet the need of accessing documents.

[0003] However, the inventor found that during actual use, due to reasons such as uneven ground, non-standard rail laying or incomplete debugging of the compact shelf, there may be gaps when adjacent rack bodies are closed.

[0020] An adjusting member is provided on the chassis main body, the adjusting member is movably connected to the chassis main body, and the roller is connected to the adjusting member through a rotating shaft. The first driving member is connected to the chassis main body and can drive the adjusting member to move relative to the chassis main body along the moving direction of the chassis of the compact rack (i.e., the first direction). Since the chassis of the compact rack is mainly supported by the rollers, when the first driving member works, under the action of the weight of the frame body, the friction between the rollers and the ground track is large and it is difficult to move, which will cause the adjusting member rotatably connected to the rollers to move difficultly. In this way, the first driving member will drive the chassis main body to move relative to the adjusting member to realize fine adjustment of the chassis main body, and finally make the adjacent frame bodies more accurately aligned in the horizontal direction, effectively reducing the gap caused by the horizontal deviation. At the same time, the second driving member is connected to the chassis main body and can drive the adjusting member to move along the height direction of the chassis of the compact rack (i.e., the second direction), so as to finely adjust the height of the chassis main body, ensure that the adjacent frame bodies are consistent in the vertical direction, and avoid the gap caused by the vertical deviation. This dual adjustment mechanism in the horizontal and vertical directions enables the adjacent frame bodies to fit closely when closed, thereby reducing the probability of gaps appearing when the adjacent frame bodies are closed.

[0037] In the related art, the compact storage rack includes a compact storage rack chassis and a rack body provided on the compact storage rack chassis. Among them, the compact storage rack chassis includes a chassis main body 1 and rollers 2, and the rollers 2 are rotatably provided on the chassis main body 1. After the compact storage rack chassis is assembled on the ground track, the chassis main body 1 is spaced from the ground track, and the gravity is transmitted to the ground track through the rollers 2, and the walking of the compact storage rack chassis can be realized through the rollers 2. However, due to reasons such as uneven ground, non-standard track laying, or the compact storage rack not being fully debugged, the rack body carried by the compact storage rack chassis may be inclined. Although the inclination amplitude is small, it will cause gaps when adjacent racks are closed, which not only affects the appearance, but also requires a large amount of time for installers to adjust and repair during maintenance.

[0038] Such as Figure 1 、 2As shown in the figure, to solve the above problems, an embodiment of the present invention provides a chassis for a compact storage rack, including a chassis main body 1, rollers 2, a rotating shaft 3, an adjusting member 4, a first driving member 5, and a second driving member 6; the adjusting member 4 is movably connected to the chassis main body 1; the rollers 2 are rotatably connected to the adjusting member 4 through the rotating shaft 3; the first driving member 5 is connected to the chassis main body 1 and is configured to drive the adjusting member 4 and the chassis main body 1 to move relatively in a first direction, and the first direction is consistent with the moving direction of the chassis of the compact storage rack; the second driving member 6 is connected to the chassis main body 1 and is configured to drive the adjusting member 4 to move in a second direction, and the second direction is consistent with the height direction of the chassis of the compact storage rack.

[0039] It should be understood that in this embodiment, the moving direction (the first direction) of the chassis of the compact storage rack refers to the direction in which it moves along the ground track, such as Figure 1 the direction where the X-axis is located as shown.

[0040] Specifically, as Figure 2 shown, in the structure of the chassis of the compact storage rack, the chassis main body 1 includes a partition 12, and the adjusting member 4 is movably connected to the partition 12; the rollers 2 are rotatably connected to the adjusting member 4 through the rotating shaft 3; the first driving member 5 is arranged on the partition 12 and is used to drive the adjusting member 4 to move in the direction where the X-axis is located; the second driving member 6 is arranged on the partition 12 and is used to drive the adjusting member 4 to move in the height direction of the chassis of the compact storage rack.

[0041] In this alternative embodiment, an adjusting member 4 is provided on the chassis main body 1, and the adjusting member 4 is movably connected to the chassis main body 1. The rollers 2 are connected to the adjusting member 4 through the rotating shaft 3. The first driving member 5 is connected to the chassis main body 1 and can drive the adjusting member 4 and the chassis main body 1 to move relatively in the moving direction of the chassis of the compact storage rack (i.e., the first direction). Since the chassis of the compact storage rack is mainly supported by the rollers 2, when the first driving member 5 works, the rollers 2 have a large friction force with the ground track under the weight of the rack body and are difficult to move, which will cause the adjusting member 4 rotatably connected to the rollers 2 to move difficultly. Thus, the first driving member 5 will drive the chassis main body 1 to move relative to the adjusting member 4 to achieve fine adjustment of the chassis main body 1, and finally make the adjacent racks more accurately aligned in the horizontal direction, effectively reducing the gaps caused by horizontal deviation. At the same time, the second driving member 6 is connected to the chassis main body 1 and can drive the adjusting member 4 to move in the height direction of the chassis of the compact storage rack (i.e., the second direction), so as to fine-tune the height of the chassis main body 1 and ensure that the adjacent racks are consistent in the vertical direction, avoiding the gaps caused by vertical deviation. This dual adjustment mechanism in the horizontal and vertical directions enables the adjacent racks to fit tightly when they are closed, thereby reducing the probability of gaps appearing when the adjacent racks are closed.

[0042] It should be understood that in this embodiment, the fine-tuning range of the chassis of the compact shelving is only at the millimeter level, usually about 2 to 4 millimeters.

[0043] Optionally, the chassis of the compact shelving further includes a first connecting shaft 7 and an elastic member 8; the adjusting member 4 is provided with at least two mounting holes 41; the chassis main body 1 is provided with adjusting holes 11 corresponding to the mounting holes 41, and the adjusting holes 11 extend along the first direction; the first connecting shaft 7 passes through the mounting holes 41 and the adjusting holes 11 to connect the adjusting member 4 and the chassis main body 1; the outer wall of the first connecting shaft 7 and the top wall of the adjusting hole 11 are spaced apart by the elastic member 8.

[0044] It should be understood that since the weight of the rack on the chassis main body 1 is ultimately transmitted to the ground track by the rollers 2, when the first driving member 5 works, the chassis main body 1 moves relative to the first connecting shaft 7 through the adjusting holes 11; at the same time, while the elastic member 8 meets the load-bearing requirement, it still must retain part of its elastic deformation ability, that is to say, when the compact shelving is in use, the elastic member 8 is not in the extreme compression state.

[0045] Specifically, as Figure 5 shown, the adjusting member 4 is provided with two mounting holes 41, and the two mounting holes 41 are symmetrically arranged on both sides of the rotating shaft 3; as Figure 6 shown, the chassis main body 1 is provided with adjusting holes 11 corresponding to the mounting holes 41, and the adjusting holes 11 extend along the X-axis; the first connecting shaft 7 passes through the mounting holes 41 and the adjusting holes 11 and is locked by nuts to connect the adjusting member 4 and the chassis main body 1; the elastic member 8 is a high-strength spring, which is arranged at the adjusting holes 11 and abuts against the outer wall of the first connecting shaft 7, so that the outer wall of the first connecting shaft 7 and the top wall of the adjusting hole 11 are spaced apart.

[0046] In this optional embodiment, the mounting holes 41 on the adjusting member 4 and the adjusting holes 11 on the chassis main body 1 are connected by the first connecting shaft 7, and the adjusting holes 11 extend along the moving direction (the first direction) of the chassis of the compact shelving. Therefore, during the fine-tuning process of the chassis main body 1, the chassis main body 1 can move relative to the rotating shaft 3 along the first direction through the adjusting holes 11. At the same time, the setting of the elastic member 8 can make the connecting shaft have space to move upward, avoiding the direct hard abutment between the outer wall of the connecting shaft and the inner wall of the adjusting hole 11 and thus unable to achieve lifting; and when the second driving member 6 drives the adjusting member 4 to move in the vertical direction, the movement of the first connecting shaft 7 in the adjusting hole 11 will cause the elastic member 8 to undergo elastic deformation. This elastic deformation not only provides a buffering effect for the adjusting member 4, avoiding structural damage caused by sudden vertical movement, but also enables the adjusting member 4 to return to the initial state through the restoring force of the elastic member 8 after the second driving member 6 cancels the applied force, further ensuring the stability of the chassis of the compact shelving in the vertical direction.

[0047] In this embodiment, the adjusting hole 11 is a long hole or a waist-shaped hole extending along the first direction, which is not limited here and is determined according to actual requirements.

[0048] Optionally, the chassis of the mobile rack further includes a first rack 9 and a first gear 20; the first rack 9 extends along the first direction, and the first rack 9 is slidably connected to the chassis body 1 along the first direction and is slidably connected to the adjusting member 4 along the second direction; the first driving member 5 includes a first motor 51, and the driving end of the first motor 51 is in transmission connection with the first rack 9 through the first gear 20.

[0049] Specifically, as Figure 3 shown, the first rack 9 is slidably arranged on the partition 12 of the chassis body 1 along the X-axis direction and is slidably connected to the adjusting member 4 along the height direction of the chassis body 1; as Figure 7 shown, the first driving member 5 includes a first motor 51, the driving end of the first motor 51 is coaxially connected with a first gear 20, and the first gear 20 meshes with the first rack 9.

[0050] In this alternative embodiment, the first rack 9 is slidably connected to the chassis body 1 along the moving direction (the first direction) of the chassis of the mobile rack, that is, the first rack 9 can slide relative to the chassis body 1 along the moving direction of the chassis of the mobile rack; since the driving end of the first motor 51 is in transmission connection with the first rack 9 through the first gear 20, and the first rack 9 is connected to the adjusting member 4, when the first motor 51 works, the chassis body 1 moves relative to the first rack 9 and the rollers 2 along the first direction to achieve fine adjustment, so that the gap caused by the horizontal position deviation can be effectively reduced when the mobile racks are closed, and the alignment accuracy of the mobile racks is improved. Secondly, the design that the first rack 9 is slidably connected to the adjusting member 4 along the height direction (the second direction) of the chassis body 1 enables the first rack 9 and the chassis body 1 to move up and down relative to the adjusting member 4 when the second motor 61 works, avoiding interference between the adjusting member 4 and the first rack 9 during the vertical movement. Since the adjusting member 4 needs to move up and down along the height direction (the second direction) of the chassis body 1 under the drive of the second driving member 6, this sliding connection method enables the adjusting member 4 to move up and down freely without being blocked by the first rack 9, thus ensuring the movement accuracy and flexibility of the adjusting member 4 in the vertical direction. This ingenious design not only improves the adjustment performance of the chassis of the mobile rack in the horizontal and vertical directions, but also enhances the reliability and stability of the entire system, providing a strong guarantee for the efficient operation of the mobile rack.

[0051] Optionally, the first rack 9 is provided with a slider 91, and the adjusting member 4 is provided with a slideway 42, and the slider 91 is slidably arranged in the slideway 42 along the second direction.

[0052] Specifically, asFigure 8 As shown, a slider 91 is provided at the lower end of the first rack 9; as Figure 5 shown, a slideway 42 cooperating with the slider 91 is provided at the upper end of the adjusting member 4, and the first rack 9 is slidably connected to the adjusting member 4 through the slider 91 and the slideway 42.

[0053] In this embodiment, when the second driving member 6 drives the adjusting member 4 to move up and down along the height direction (the second direction) of the chassis main body 1, relative movement can occur between the slider 91 and the slideway 42 in the height direction of the chassis main body 1, so that the adjusting member 4 can move up and down smoothly and precisely under the drive of the second driving member 6 without being blocked by the first rack 9.

[0054] Optionally, the mobile rack chassis further includes a second rack 10 and a second gear 30; the second rack 10 extends along the first direction, and the second rack 10 is slidably connected to the chassis main body 1 along the first direction; a first guiding surface 101 is provided at an end of the second rack 10 along its length direction; the second driving member 6 includes a second motor 62, and a driving end of the second motor 62 is in transmission connection with the second rack 10 through the second gear 30; when the second driving member 6 drives the second rack 10 to move towards the adjusting member 4 along the first direction, the first guiding surface 101 of the second rack 10 is configured to abut against the bottom of the adjusting member 4 to lift the adjusting member 4.

[0055] Specifically, as Figure 3 shown, the second rack 10 is located below the first rack 9 and is slidably connected to a partition 12 of the chassis main body 1 along the direction where the X axis is located; as Figure 10 shown, a first guiding surface 101 is provided at an end of the second rack 10 along its length direction; as Figure 9 shown, the second driving member 6 includes a second motor 62, a driving end of the second motor 62 is coaxially connected with a second gear 30, and the second gear 30 meshes with the second rack 10; when the second driving member 6 drives the second rack 10 to move towards the adjusting member 4 along the first direction, the first guiding surface 101 of the second rack 10 abuts against the bottom of the adjusting member 4 to lift the adjusting member 4.

[0056] In this optional embodiment, when the second motor 62 drives the second rack 10 to move towards the adjusting member 4, the first guiding surface 101 at the end of the second rack 10 can contact the adjusting member 4 and gradually lift the adjusting member 4, thereby realizing the lifting movement of the adjusting member 4. This design is not only simple in structure, but also ensures the accuracy and stability of the adjustment process through the transmission of the rack and the gear. At the same time, the design of the first guiding surface 101 makes the lifting process of the adjusting member 4 smoother, reduces mechanical shock and damage that may be caused by sudden vertical movement, and further improves the service life and reliability of the mobile rack chassis.

[0057] In this embodiment, the first guiding surface 101 is a guiding inclined surface or a guiding arc surface, which is not limited here and is determined according to actual requirements.

[0058] Optionally, the adjusting member 4 is provided with a second guiding surface 43, and the second guiding surface 43 is located on the moving path of the end of the second rack 10 where the first guiding surface 101 is provided.

[0059] Specifically, the second guiding surface 43 is a guiding inclined surface or a guiding arc surface, which is not limited here and is determined according to actual requirements. As Figure 5 shown, the second guiding surface 43 is a guiding arc surface and is located on the moving path of the end of the second rack 10 where the first guiding surface 101 is provided.

[0060] In this optional embodiment, when the second rack 10 moves along the first direction towards the adjusting member 4 under the drive of the second motor 62, the first guiding surface 101 at its end can accurately contact and cooperate with the second guiding surface 43 on the adjusting member 4. This cooperation of the guiding surfaces not only ensures the smooth lifting of the adjusting member 4 in the vertical direction, avoiding shaking or jamming caused by unstable contact, but also further improves the positioning accuracy and stability of the adjusting member 4 during the lifting and lowering process. Through this ingenious guiding design, the chassis of the compact rack can be lifted more smoothly and efficiently during the lifting process, reducing mechanical wear and extending the service life of the equipment.

[0061] Optionally, the outer contour of the chassis main body 1 is rectangular; at least one of the two ends of the chassis main body 1 along the length direction is provided with at least one of the rollers 2; at least two of the rollers 2 are provided at the other end of the chassis main body 1 along the length direction; the plurality of rollers 2 are respectively rotatably connected to the plurality of adjusting members 4 through the corresponding rotating shafts 3.

[0062] Specifically, as Figure 1 shown, the outer contour of the chassis main body 1 is rectangular; two rollers 2 are provided at both ends of the chassis main body 1 along the length direction, and the two rollers 2 at the same end are spaced along the direction of the X axis, and the four rollers 2 are respectively rotatably connected to the four adjusting members 4 through the corresponding rotating shafts 3.

[0063] In this optional embodiment, at least one roller 2 is provided at one end of the chassis main body 1 along the length direction, and at least two rollers 2 are provided at the other end and are spaced horizontally. This design not only enhances the support stability of the chassis, but also ensures the smoothness and flexibility of the compact rack during the moving process through the reasonable distribution of the rollers 2. At the same time, since the plurality of rollers 2 are respectively rotatably connected to the plurality of adjusting members 4 through the corresponding rotating shafts 3, separate adjustment and common adjustment of multiple positions of the chassis main body 1 can be achieved.

[0064] Meanwhile, since the second driving member operates when the frame tilts forward or backward, the rollers 2 at the same end of the second driving member in the front-back direction do not need to operate simultaneously. Thus, all the rollers 2 at the same end in the length direction of the chassis main body 1 are driven by one second driving member 6, which can reduce the number of second driving members 6 and thereby lower the cost.

[0065] An embodiment of the present invention provides a method for controlling a chassis of a compact rack, using the above-described chassis of the compact rack, including:

[0066] When it is detected that the frame installed on the chassis of the compact rack has not moved into place, control the first driving member 5 and / or the second driving member 6 corresponding to the chassis of the compact rack to operate to drive the adjusting member 4 to move relative to the chassis main body 1 until the frame installed on the chassis of the compact rack moves into place.

[0067] In this embodiment, proximity sensors are respectively arranged at the upper and lower positions at both ends of the frame edge to detect whether the frame is in place. The proximity sensors adopt non-contact inductive proximity sensors, which have advantages such as high detection accuracy and strong reliability. The proximity sensors are connected to the controller and transmit the detected signals to the controller. The controller is composed of a processor, a storage module, an input-output interface, and a communication interface. The processor selects a high-performance microcontroller (MCU) that can quickly process complex data transmitted by the sensors. The storage module is divided into a read-only memory (ROM) and a random-access memory (RAM) to meet the data access requirements during the high-speed operation of the processor. The input-output interface is a bridge connecting external devices. The input interface is connected to the proximity sensors, receives the weak electrical signals output by them, and performs conditioning such as amplification, filtering, and analog-to-digital conversion to convert them into digital signals that can be analyzed by the processor. The output interface is connected to the motor driver and outputs the control signals (such as pulse, voltage, or current commands) calculated by the processor to control the operation of the motor. The communication interface provides a channel for communicating with the host computer and enables the host computer to monitor the running state of the compact rack in real time.

[0068] In this embodiment, when the frame of the compact rack starts to move, the controller monitors the signals of the proximity sensors in real time. When the frame approaches the closing position, the proximity sensors start to operate. If the frame tilts during the closing process, resulting in some proximity sensors not detecting the trigger signal, the controller will judge the tilt direction and degree of the frame according to the position information of the untriggered proximity sensors. Then, the controller sends control signals to the motors at the corresponding positions to control the first driving member 5 and / or the second driving member 6 of the chassis of the compact rack to operate. Through continuous detection and adjustment, until all the proximity sensors detect the trigger signals, indicating that the frame has been accurately in place, at this time the controller stops controlling the first driving member 5 and / or the second driving member 6.

[0069] In this embodiment, the first driving member 5 and the second driving member 6 are stepper motors, which are open-loop control motors that convert electrical pulse signals into angular displacement or linear displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (referred to as the "step angle") in the set direction. By controlling the number of pulses, the angular displacement amount can be controlled to achieve the purpose of accurate positioning; at the same time, by controlling the pulse frequency, the rotation speed and acceleration of the motor can be controlled to achieve the purpose of speed regulation. In the chassis of the mobile rack of the present invention, after the controller determines the direction and distance to be adjusted according to the signal of the proximity sensor, it sends pulse signals with corresponding quantity and frequency to the stepper motor driver. For example, when it is detected that one side of the rack body is too low and the adjusting member 4 needs to be raised, the controller will send a certain number of pulse signals to the driver of the corresponding stepper motor. After receiving the pulse signals, the stepper motor rotates according to the set step angle, and through a transmission mechanism (such as a rack and pinion transmission), the rotational motion is converted into a linear lifting motion of the adjusting member 4, so that the adjusting member 4 rises to an appropriate height to adjust the inclination of the rack body.

[0070] Optionally, controlling the first driving member 5 and / or the second driving member 6 of the corresponding mobile rack chassis to operate to drive the adjusting member 4 to perform relative movement with the chassis main body 1 includes:

[0071] When it is detected that the end of the rack body in the length direction has not moved in place, controlling the first driving member 5 of the mobile rack chassis to drive the adjusting member 4 at the corresponding end to perform relative movement with the chassis main body 1 in the first direction until the end of the rack body in the length direction moves in place;

[0072] When it is detected that the end of the rack body in the height direction has not moved in place, controlling the second driving member 6 of the mobile rack chassis to drive the adjusting member 4 to move in the second direction until the end of the rack body in the height direction moves in place.

[0073] In this embodiment, the proximity sensor continuously and real-time monitors the relative distance between the rack body and the target position (the closing or fully open position). When the rack body gradually approaches the target position, the proximity sensor will sense the approach of the target object (such as an adjacent rack body or a fixed limit structure), and convert the detected distance information into an electrical signal and send it to the controller. This enables the controller to always grasp the position state of the rack body, providing a basis for subsequent judgment and control. When the rack body reaches the predetermined closing position, normally the proximity sensor should detect the target object and trigger the corresponding signal. The controller determines whether the rack body is in place accurately by receiving the trigger signal from the proximity sensor. If all proximity sensors are triggered normally, it indicates that the rack body has accurately reached the target position; if one or some proximity sensors do not trigger the signal, it means that the corresponding moving column part at this position is not in place, and there may be tilting or other displacement deviations. Since proximity sensors are provided at the upper and lower positions at both ends of the rack body edge, by comparing the trigger situations of the proximity sensors at the upper and lower positions on the same side and the trigger situations of the proximity sensors on different sides, it can be determined whether the rack body is tilted. For example, when the upper proximity sensor at one end of the rack body is triggered while the lower proximity sensor is not triggered, it indicates that there may be an upward tilt at this end; if the proximity sensors on one side are not triggered while the proximity sensors on the other side are triggered normally, it means that the whole rack body is tilted towards the side where no trigger occurs. These tilt information will be timely fed back to the controller for subsequent adjustment operations. During the process that the controller issues a control signal according to the information fed back by the proximity sensor to drive the first motor 51 or the second motor 62 to adjust the position of the adjusting member 4, the proximity sensor will continuously monitor the position change of the rack body. The controller judges whether the adjustment reaches the expected effect according to these real-time feedback information. If there is still a situation where a proximity sensor is not triggered, it means that the adjustment is not in place, and the controller will continue to control the first motor 51 or the second motor 62 to further adjust the adjusting member 4 until all proximity sensors are triggered normally and the moving column is in place accurately.

[0074] Optionally, controlling the first driving member 5 and / or the second driving member 6 corresponding to the chassis of the compact rack to work to drive the adjusting member 4 to have a relative movement with the chassis main body 1 further includes:

[0075] When it is detected that both the end of the rack body in the length direction and the end of the rack body in the height direction are not in place, first control the second driving member 6 to drive the adjusting member 4 to move in the second direction so that the end of the rack body in the height direction is in place; then control the first driving member 5 to drive the adjusting member 4 at the corresponding end to have a relative movement with the chassis main body 1 in the first direction so that the end of the rack body in the length direction is in place.

[0076] In this embodiment, by first ensuring that the ends of the frame move into place in the height direction, the stability of the frame in the vertical direction can be effectively guaranteed, avoiding the inclination or shaking of the frame caused by deviations in the height direction, thereby providing a solid foundation for subsequent horizontal adjustment. On this basis, by then performing horizontal adjustment, the ends of the frame in the length direction can be accurately positioned, ensuring the tight fit between adjacent frames and effectively avoiding the gap problem caused by the failure to reach the position in the horizontal direction. This sequential adjustment not only improves the installation accuracy and stability of the compact rack, but also optimizes the adjustment efficiency and reduces the cumbersome operations and time costs caused by multiple adjustments.

[0077] Although the present invention is disclosed as above, the scope of protection of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the scope of protection of the present invention.
