Description

Technical Field

[0001] This invention relates to the field of storage equipment technology, and in particular to a storage component and a storage cabinet containing the same. Background Technology

[0002] Lockers can be used to store items such as valuables and communication equipment. Shielded cabinets are lockers that isolate the transmission of electromagnetic waves. Their principle is to use conductive or magnetic materials to confine electromagnetic radiation within a defined spatial range. The purpose is to surround electromagnetic interference sources with a shield to suppress interference from the source to receivers in the surrounding space, or to surround receivers with a shield to prevent interference from the source. Shielded cabinets typically contain storage compartments for storing communication equipment.

[0003] Chinese utility model patent CN218456630U discloses a storage component and a shielded cabinet including it. It also discloses a drawer box with an interlocking door, meaning that extending the box forward opens and closes the door, while sliding it backward closes the door. However, this technical solution uses a drive device consisting of a motor, lead screw, and slider to drive the drawer box to slide back and forth. During the drawer's extension and retraction, the lead screw needs to rotate at high speed to quickly extend and retract the drawer; however, the manufacturing cost of a high-speed rotating lead screw is high, and when the motor malfunctions, the lead screw can easily seize up, making it impossible to pull the drawer out. This results in the need to forcibly remove the drawer or open the entire storage cabinet to retrieve the user's items, leading to high after-sales maintenance time and costs.

[0051] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0052] In the description of this invention, it should be understood that "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0053] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0054] Please refer to the following: Figures 1 to 20 The register component provided in the embodiments of the present invention will now be described. The first direction is the X direction in the figure, and the second direction is the Y direction in the figure;

[0055] like Figure 1 and Figure 2As shown, the register component of this embodiment includes a register unit 100 and a drive unit 200;

[0056] The storage unit 100 includes a box frame 110 and a drawer box 120. The box frame 110 has a slide groove 111, which extends along a first direction X and has a slot 112 facing forward in the first direction X. The drawer box 120 is slidably disposed in the slide groove 111 along the first direction X. That is, the drawer box 120 can slide back and forth in the first direction X. "Forward" refers to the direction in which the drawer box 120 slides toward the user, and "backward" refers to the direction in which the drawer box 120 slides away from the user.

[0057] The drive unit 200 is used to drive the drawer box 120 to slide along the first direction X, so that the drawer box 120 switches between an extended state and a retracted state; in this embodiment, the front end of the drawer box 120 extends out of the slide groove 111, which is the extended state, such as... Figure 18 , Figure 19 As shown; the front end of drawer box 120 is located within slide groove 111, which is the folded-back state, as... Figure 1 , Figure 17 As shown;

[0058] Reference Figure 2 The drive unit 200 includes a power unit 210 and a transmission mechanism 220. The transmission mechanism 220 includes a driving member 221, a first gear 222, and a first rack 223. The first rack 223 is fixed on the drawer box 120. The power unit 210 is connected to the transmission mechanism 220 to make the driving member 221 rotate. The length direction of the first rack 223 is arranged along the first direction X and is used to guide the movement direction of the drawer box 120. The driving member 221 can drive the first gear 222 to rotate. The first gear 222 can mesh with the first rack 223. That is, when the first gear 222 meshes with the first rack 223, the driving member 221 drives the first gear 222 to rotate, so as to drive the first rack 223 to move back and forth along the first direction X, so as to switch the drawer box 120 between the extended state and the retracted state.

[0059] Reference Figure 2 , Figure 5 , Figure 6The storage assembly further includes: a self-locking unit 300; the first rack 223 is disposed on the outside of the drawer box 120; the self-locking unit 300 is used to lock the drawer box 120 in the storage state; the self-locking unit 300 includes a self-locking slider 310; the self-locking slider 310 is slidably connected to the box frame 110; the self-locking slider 310 is provided with a second rack 312; the second rack 312 can mesh with the first gear 222, the self-locking slider 310 can move along a predetermined moving path, so that the second rack 312 moves relative to the first gear 222, and the self-locking slider 310 contacts the drawer box 120, the first gear 222 disengages from the first rack 223, thereby locking the drawer box 120 in the storage state.

[0060] When the drawer box 120 is in the retracted state, the self-locking slider 310 can move along a predetermined movement path. At this time, the second rack 312 meshes with the first gear 222, causing the second rack 312 to move relative to the first gear 222. Simultaneously, the self-locking slider 310 contacts the drawer box 120 to lock it in place, preventing the drawer box 120 from moving back and forth in the first direction X. It should be noted that since the first rack 223 is disengaged from the first gear 222 at this time, the rotation of the first gear 222 will only move the second rack 312, not the first rack 223. This prevents the first gear 222 from driving the drawer box 120 to move back and forth in the first direction X via the first rack 223, thus achieving the purpose of locking the drawer box 120 in the retracted state.

[0061] In some embodiments of the present invention, to enable the self-locking slider to move along a predetermined movement path, the self-locking unit 300 further includes a moving part and a guide part. The guide part is disposed on the drawer box 120, and the corresponding moving part is disposed on the self-locking slider 310. The guide part and the moving part cooperate to enable the self-locking slider 310 to move along the predetermined movement path. Depending on the different forms of the guide part and the moving part, there are two types: one where the moving part is a pin 311, and the other where the moving part is a self-locking groove 320a.

[0062] When the moving part is pin 311, refer to Figure 2 , Figure 5 , Figure 6The guide portion also includes a self-locking groove 320. The self-locking slider 310 is provided with a pin 311; the self-locking slider 310 is provided with a second rack 312, the pin 311 is inserted into the self-locking groove 320, the pin 311 can reciprocate within the self-locking groove 320, causing the second rack 312 to move relative to the first gear 222, and the first gear 222 disengages from the first rack 223, at which time the drawer box 120 is in the storage state; that is, when the drawer box 120 moves to the storage state under the drive of the drive unit 200, the second rack 312 meshes with the first gear 222, and under the drive of the first gear 222, the second rack 312 and the self-locking slider 310 move in the second direction Y, so that the pin 311 is inserted into the self-locking groove 320 to lock the drawer box 120 in the storage state, thus preventing the drawer box 120 from being forcibly pulled out by external force, preventing the stored items from being taken away by other people who are not the owner, and ensuring the safety of the stored items.

[0063] When it is necessary to release the self-locking of drawer box 120, the drive unit 200 can drive the second rack 312 to move in the opposite direction through the first gear 222, so that the pin 311 disengages from the self-locking groove 320 and releases the self-locking state of drawer box 120. At this time, the drive unit 200 can be guided to extend forward by engaging the first rack 223 with the first gear 222 through the transmission mechanism 220.

[0064] It is understandable that when the latch 311 is located in the self-locking groove 320, if an external force grabs the drawer box 120 and pulls it forward, the drawer box 120 is locked by the self-locking groove 320 and the latch 311, preventing it from extending forward. Furthermore, since the first gear 222 is disengaged from the first rack 223, even if the drawer box 120 has a tendency to move forward, the external force cannot drive the first gear 222 to rotate through the first rack 223. Therefore, the external force cannot pull the drawer box 120 to rotate the first gear 222 and drive the second rack 312, the self-locking slider 310, and the latch 311 to move. Thus, the external force cannot pull the drawer box 120 forward to release its self-locking state, preventing stored items from being taken by unauthorized personnel and ensuring the safety of stored items. In some embodiments of the present invention, the sliding direction of the self-locking slider 310 is the second direction Y, which is perpendicular to the first direction X, and the extension direction of the self-locking groove 320 is parallel to the second direction Y. The extension direction of the self-locking groove 320 is parallel to the movement direction of the pin 311 of the self-locking slider 310, so that the pin 311 of the self-locking slider 310 can directly extend into the self-locking groove 320 along the second direction Y, thereby better locking the drawer box 120 in the stored state. Moreover, the extension direction of the self-locking groove 320 is perpendicular to the first direction X. Therefore, the groove walls of the self-locking groove 320 are all perpendicular to the first direction X. When the pin 311 is inserted into the self-locking groove 320, if the drawer box 120 is pulled outward under the action of external force, the pressure applied by the drawer box 120 to the pin 311 will be perpendicular to the second direction Y, and it will be impossible to push the pin 311 and the self-locking slider 310 to slide, ensuring that the drawer box 120 can be locked in the stored state.

[0065] It can be understood as referring to Figure 20 The box frame 110 is provided with a fixing frame 117. The fixing frame 117 has a moving groove 118 extending along the second direction Y. The moving groove 118 is slidably connected to the self-locking slider 310 to ensure that the self-locking slider 310 can move back and forth along the second direction Y.

[0066] Understandably, the bolt 311 is cylindrical to better slide along the self-locking groove 320. Furthermore, when the bolt 311 is inserted into the self-locking groove 320, if an external force pulls the drawer box 120 at this time, the pressure of the self-locking groove 320 on the bolt 311 is parallel to the first direction X, preventing the self-locking slider 310 from moving along the second direction Y, thus ensuring the self-locking function of the drawer box 120. In addition, the shape of the bolt 311 can be adjusted according to actual needs; the bolt 311 can also be in commonly used shapes such as a triangular prism or a square prism.

[0067] In some specific embodiments, the moving direction of the self-locking slider 310 may not be perpendicular to the first direction X, and the extension direction of the corresponding self-locking groove 320 may also be adjusted according to the actual situation, so as to ensure that the first gear 222 drives the pin 311 of the self-locking slider 310 to insert into the self-locking groove 320 to lock the drawer box 120 in the storage state.

[0068] In some embodiments of the present invention, reference is made to... Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The guide portion further includes: a first guide groove 330; the first guide groove 330 communicates with the self-locking groove 320, and the first guide groove 330 is inclined backward relative to the self-locking groove 320, and the angle θ between the extension direction of the first guide groove 330 and the second direction Y is greater than 10 degrees and less than 80 degrees; the first guide groove 330 has a first position and a second position, the first position being closer to the self-locking groove 320 than the second position, the pin 311 being able to reciprocate between the first position and the second position, and the pin 311 being able to engage the second rack 312 with the first gear 222 in the first position, and the first gear 222 disengaging from the first rack 223 in the second position; the pin 311 being able to engage the first rack 223 with the first gear 222 in the second position, and the first gear 222 disengaging from the second rack 312.

[0069] It should be noted that, referring to Figure 7 and Figure 8 When the pin 311 is located in the self-locking groove 320, the drive unit 200 drives the first gear 222 to rotate forward, which can move the self-locking slider 310 forward in the second direction Y through the second rack 312, so that the pin 311 moves forward from the self-locking groove 320 to the first guide groove 330 and reaches the first position; at this time, the second rack 312 meshes with the first gear 222, and the first gear 222 disengages from the first rack 223; when the first gear 222 continues to rotate forward, the pin 311... 1. The pin 311 abuts against the wall of the first guide groove 330. Since the angle θ between the extension direction of the first guide groove 330 and the second direction Y is greater than 10 degrees and less than 80 degrees, the angle between the direction of the pressure F1 applied by the pin 311 to the drawer box 120 through the first guide groove 330 and the forward extension direction of the drawer box 120 is less than 90 degrees. Therefore, the pin 311 can push the drawer box 120 forward through the first guide groove 330. At this time, the pin 311 gradually moves from the first position to the second position. (Refer to...) Figure 9 and Figure 10When the latch 311 reaches the second position of the first guide groove 330, the drawer box 120 has moved forward the distance between the first and second positions of the first guide groove 330. At this time, the first rack 223 will mesh with the first gear 222, and the first gear 222 will disengage from the second rack 312. If the first gear 222 continues to rotate forward, the drawer box 120 can continue to move forward through the cooperation of the first gear 222 and the first rack 223.

[0070] Reference Figure 7 and Figure 8 That is, when it is necessary to drive the drawer box 120 to move forward in the stored state, the first gear 222 rotates forward, first driving the second rack 312, the self-locking slider 310, and the pin 311 to move forward, causing the pin 311 to disengage from the self-locking groove 320, thus releasing the self-locking of the drawer box 120, and allowing the pin 311 to move to the first position of the first guide groove 330. At this time, the first gear 222 cannot drive the drawer box 120 to slide forward through the first rack 223, but the pin 311 pushes the groove wall of the first guide groove 330, causing the drawer box 120 to move forward; see reference. Figure 9 and Figure 10 When the latch 311 moves to the second position of the first guide groove 330 under the drive of the first gear 222, the drawer box 120 has moved forward a certain distance, allowing the first gear 222 to mesh with the first rack 223 moving in the forward and backward direction. The second rack 312 disengages from the first gear 222, and the first gear 222 continues to rotate forward, which can push the drawer box 120 to slide forward to the extended state. The second rack 312 and the self-locking slider 310 will not interfere with the forward sliding of the drawer box 120, ensuring that the drawer box 120 can slide forward normally to the extended state. It should be noted that when the first gear 222 drives the drawer box 120 to slide forward through the first rack 223, since the second gear 225 disengages from the first gear 222, the latch 311 and the self-locking slider 310 will not continue to move in the second direction Y under the drive of the first gear 222, and will disengage from the first guide groove 330 or continue to move along the first guide groove 330.

[0071] Reference Figure 7 and Figure 9In this embodiment, the second position of the first guide groove 330 corresponds to the end of the first guide groove 330 away from the self-locking groove 320. That is, when the first gear 222 drives the drawer box 120 to slide forward through the first rack 223, the first guide groove 330 also slides forward. At this time, the pin 311 stops moving along the second direction Y. Since the first guide groove 330 slides forward, the pin 311 disengages from the first guide groove 330, avoiding interference between the drawer box 120 and the pin 311 and the self-locking slider 310 when the drawer box 120 moves forward. The pin 311 stops at the position corresponding to the second position in the first direction X, which reduces the stroke of the self-locking slider 310 in the second direction Y. When the pin 311 is in the first position, the second rack 312 is engaged with the first gear 222 so that the first gear 222 pushes the pin 311 from the first position to the second position.

[0072] Understandably, referring to Figure 11 and Figure 12 When drawer box 120 extends forward to its extended state, the first rack 223 meshes with the first gear 222. When drawer box 120 needs to slide backward from its extended state to its retracted state, drive unit 200 drives the first gear 222 to reverse. The first gear 222 drives drawer box 120 to slide backward via the first rack 223. During the continuous backward sliding of drawer box 120, since the latch 311 is at the second position corresponding to the first direction X, the first guide groove 330 moves backward, and the latch 311 will re-enter the first guide groove 330 and move to the second position of the first guide groove 330. (Refer to...) Figure 11 At this time, the first guide groove 330 will continue to slide backward under the drive of the first gear 222. Since the angle θ between the extension direction of the first guide groove 330 and the second direction Y is greater than 10 degrees and less than 80 degrees, the angle between the direction of the pressure F2 exerted by the groove wall of the first guide groove 330 on the pin 311 and the direction of the self-locking slider 310 sliding in the opposite direction is less than 90 degrees. Therefore, the pin 311 and the self-locking slider 310 slide in opposite directions under the push of the first guide groove 330. Then the pin 311 will move to the first position along the extension direction of the first guide groove 330, so that the first gear 222 meshes with the second rack 312 and the first gear 222 separates from the first rack 223. Figure 12At this time, the first gear 222 continues to reverse. The first gear 222 can drive the self-locking slider 310 to slide in the opposite direction through the second rack 312. At this time, the angle between the direction of the pressure F3 of the pin 311 on the groove wall of the first guide groove 330 and the direction of the drawer box 120 retracting is less than 90 degrees. Therefore, the pin 311 pushes the drawer box 120 to retract through the first guide groove 330, so that the pin 311 gradually approaches the self-locking groove 320 until the pin 311 extends into the self-locking groove 320, so that the drawer box 120 can reach the storage state and achieve the purpose of self-locking.

[0073] In addition, the second position of the first guide groove 330 can also be located in the middle of the first guide groove 330. Then, when the first gear 222 meshes with the first rack 223, the pin 311 can continue to slide along the second direction Y under the drive of the first guide groove 330.

[0074] It can be noted that, in this embodiment, the angle θ between the extension direction of the first guide groove 330 and the second direction Y can be 45°, so as to better apply the force of the pin 311 to the first guide groove 330 and the drawer box 120 to extend forward or retract backward, and also to facilitate the first guide groove 330 to drive the self-locking slider 310 to slide forward and backward through the pin 311.

[0075] In some embodiments of the present invention, reference is made to... Figure 13 and Figure 14The guide portion further includes: a second guide groove 340; the second guide groove 340 is connected to the end of the first guide groove 330 away from the self-locking groove 320; the extension direction of the second guide groove 340 is parallel to the first direction X, and the end of the second guide groove 340 away from the first guide groove 330 is also provided with an outwardly expanding guide slope 341, and the pin 311 can reciprocate within the second guide groove 340, so that the first rack 223 moves relative to the first gear 222, and the first gear 222 disengages from the second rack 312. The second guide groove 340 is parallel to the first direction X. When the pin 311 enters the second guide groove 340 from the outlet of the first guide groove 330, the second guide groove 340 can prevent the pin 311 and the self-locking slider 310 from continuing to slide forward, thereby reducing the sliding jitter of the self-locking slider 310 in the second direction Y. The setting of the second guide groove 340 can also ensure that the pin 311 can be aligned with the outlet of the first guide groove 330, so that when the drawer box 120 slides backward, the pin 311 can be aligned with the outlet of the first guide groove 330 and enter the first guide groove 330, thereby allowing the pin 311 of the self-locking slider 310 to enter the self-locking groove 320, so that the drawer box 120 can enter the storage state. The outwardly expanding guide slope 341 allows the pin 311 to enter the second guide groove 340 and the first guide groove 330 better, avoiding jamming or the pin 311 failing to enter the second guide groove 340.

[0076] In some specific embodiments, reference is made to Figure 21 When the moving part is a self-locking groove 320a, the guide part also includes a pin 311a; the pin 311a is disposed on the drawer box 120, and the self-locking slider 310 is provided with a self-locking groove 320a; the self-locking groove 320a forms the moving part, so that when the second rack 312 moves relative to the first gear 222, the self-locking groove 320a can be fitted onto the outside of the pin 311a, so that the self-locking slider 320 moves along the predetermined moving path, and the first gear 222 disengages from the first rack 223. In this case, the moving part may also include a first guide groove 330a and a second guide groove 340a. The moving path of the self-locking unit 300 with the moving part being the self-locking groove 320a is the same as the moving path of the self-locking unit 300 with the moving part being the pin 311, and their movement modes are basically mirror images of each other. Therefore, the self-locking unit 300 with the moving part being the self-locking groove 320a is only shown in the illustration, and the movement mode will not be described in detail here.

[0077] In some embodiments of the present invention, reference is made to... Figure 2Since the drawer box 120 can be self-locked by the self-locking unit 300, when the drive unit 200 malfunctions or stops due to power failure, it is no longer possible to drive the drawer box 120 to extend through the drive unit 200. Therefore, in order to facilitate the extension of the drawer box 120 in the storage state, the box frame 110 of this embodiment is provided with an emergency channel 116 for inserting an emergency unlocking tool. The extension direction of the emergency channel 116 is parallel to the first direction X, and the front end of the emergency channel 116 extends to the slot 112. The rear end of the emergency channel 116 corresponds to the first gear 222 or the transmission gear 224, so that the emergency unlocking tool passes through the emergency channel 116 to push the first gear 222 or the transmission gear 224 to rotate, so that the first gear 222 drives the pin 311 to disengage from the self-locking slot 320 through the second rack 312 to release the self-locking state. At this time, the drawer box 120 can be manually pulled out. Emergency access 116 is a through passage on the box frame 110. Emergency unlocking tool is a tool (such as a rod) that can be inserted into emergency access 116 and contact the first gear 222 or transmission gear 224. Since the first wheel 211 and the second wheel 212 are softly connected, when the emergency unlocking tool is inserted into emergency access 116, it can move the first gear 222 or transmission gear 224 to drive the first gear 222 to rotate, so that the first gear 222 rotates forward, and the first gear 222 drives the pin 311 to disengage from the self-locking groove 320 through the second rack 312, thereby releasing the self-locking of drawer box 120. This allows maintenance personnel to pull out drawer box 120 from outside the box frame 110 for easy inspection or removal of stored items placed in drawer box 120.

[0078] It should be noted that the outer diameter of the transmission gear 224 is larger than the outer diameter of the first gear 222, and the rear end of the emergency channel 116 corresponds to the transmission gear 224. This can increase the torque of the emergency unlocking tool to rotate the first gear 222, and make the emergency unlocking tool rotate the first gear 222 more effectively.

[0079] In some embodiments of the present invention, reference is made to... Figure 6To facilitate the insertion of an emergency unlocking tool into the emergency passage 116 to drive the first gear 222 to rotate forward, in this embodiment, with the first direction X as the projection direction, at least a portion of the projection of the rear outlet of the emergency passage 116 and the projection of the first rack 223 are located on opposite sides of the projection of the shaft of the first gear 222. In some preferred embodiments, the projection of the rear outlet of the emergency passage 116 and the projection of the first rack 223 are located on opposite sides of the projection of the shaft of the first gear 222. At this time, the direction of the first gear 222's forward rotation corresponds to the direction of the first rack 223's forward rotation, while the direction of rotation corresponding to the rear outlet side of the emergency passage 116's backward rotation. When the emergency unlocking tool is inserted into the emergency passage 116 from front to back, the emergency unlocking tool can rotate the first gear 222 or the transmission gear 224 backward, which corresponds to the direction of the first gear 222's forward rotation. This allows maintenance personnel to directly insert the emergency unlocking tool from front to back, which can drive the first gear 222 to rotate forward, thereby releasing the self-locking of the drawer box 120 and allowing the drawer box 120 to be taken out directly from the front.

[0080] In some specific embodiments, the width of the rear outlet of the emergency passage 116 can be increased to increase the projected area, so that part of the projection of the rear outlet of the emergency passage 116 and the projection of the first rack 223 are located on the same side of the projection of the shaft of the first gear 222, and the projection of another part of the rear outlet of the emergency passage 116 and the projection of the first rack 223 are located on opposite sides of the projection of the shaft of the first gear 222, thus ensuring that the emergency unlocking tool can rotate the first gear 222.

[0081] In some embodiments of the present invention, reference is made to... Figures 15 to 16 The drawer box 120 includes a box body 121 and a box door 122; the box body 121 is used to store items; the box door 122 is located on the front side of the box body 121; the box door 122 is used to cover the slot 112; the box door 122 is provided with an emergency through hole 123, the emergency through hole 123 being located on the front side of the emergency passage 116. When in the stored state, the box door 122 covers the slot 112, therefore, the emergency through hole 123 in the box door 122 allows maintenance personnel to take an emergency unlocking tool and insert it into the emergency passage 116 through the emergency through hole 123 to release the self-locking of the drawer box 120 in an emergency.

[0082] In some embodiments of the present invention, reference is made to... Figures 15 to 16To prevent foreign objects or other objects from blocking the emergency passage 116, the storage assembly also includes a cover 124. The cover 124 is detachably connected to the door 122 and is used to close the emergency access hole 123. The cover 124 can close the emergency access hole 123 when the storage assembly is in use, preventing foreign objects or other objects from entering through the emergency access hole 123 and closing the emergency passage 116, thus ensuring the emergency passage 116 remains usable. The cover 124 is detachably connected to the door 122. When emergency unlocking is required, maintenance personnel can remove the cover 124 and insert an emergency unlocking tool into the emergency passage 116.

[0083] In some embodiments of the present invention, reference is made to... Figures 15 to 17 The drawer box 120 further includes a linkage mechanism 130; the drawer box 120 is connected to the box door 122 via the linkage mechanism 130, and the box door 122 is hinged at the slot 112; the box door 122 has a hinge shaft 128, and the box frame 110 is provided with a hinge position 119 at the slot 112 that is hinged to the hinge shaft 128; the linkage mechanism 130 causes the box door 122 to flip away from the slot 112 when the box body 121 slides forward, and causes the box door 122 to flip towards the slot 112 when the box body 121 slides backward. Figure 16 , Figure 17 As shown, the linkage mechanism 130 includes an L-shaped linkage groove 131 and a linkage slider 132. The linkage slider 132 is disposed on the box door 122, and the bottom of the box door 122 is rotatably connected to the box frame 110. The linkage groove 131 is disposed on the box body 121 and is divided into a smooth section 133 extending along the first direction X and a vertical section 134 extending along the vertical direction. The linkage slider 132 is slidably connected to the linkage groove 131. The linkage slider 132 is cylindrical. When the drawer box 120 is in the storage state, the linkage slider 132 is at the lower end of the vertical section 134, and the box door 122 covers the groove opening 112. When the drawer box 120 extends forward, the box door 122 will be pushed by the box body 121 and flipped away from the groove opening 112, and will be located at the bottom of the drawer box 120. At this time, the linkage slider 132 will enter the smooth section 133. Figure 18 As shown, when the box body 121 slides forward, the box door 122 will not obstruct the forward sliding direction of the box body 121; when the box body 121 slides backward, the linkage slider 132 will move to the front end of the smooth section 133, and pull the box door 122 back through the linkage slider 132, so that the box door 122 flips towards the slot 112. When the box body 121 slides backward to the storage state, the box door 122 can close the slot 112.

[0084] In some embodiments of the present invention, reference is made to... Figure 2The power unit 210 includes a first wheel 211 and a second wheel 212. The first wheel 211 and the second wheel 212 are softly connected, and the second wheel 212 is connected to the driving member 221 to drive the driving member 221 to rotate. This, in turn, drives the drawer box 120 to switch between an extended state and a retracted state via the transmission mechanism 220. The first wheel 211 and the second wheel 212 are connected to form a speed reduction structure, allowing the rotational speed of the first wheel 211 to be greater than that of the driving member 221. In this embodiment, the outer diameter of the first wheel 211 is smaller than the outer diameter of the second wheel 212, so that the connection between the first wheel 211 and the second wheel 212 forms a speed reduction structure.

[0085] The first wheel 211 and the second wheel 212 are connected by a flexible connection. A flexible connection refers to a connection method that transmits power and motion through flexible elements (such as belts, ropes, chains, etc.). The connection between the first wheel 211 and the second wheel 212 allows for a certain degree of elastic deformation to buffer impacts and absorb vibrations, thereby reducing noise when the first wheel 211 and the second wheel 212 transmit power. Therefore, the power unit 210, through the flexible connection of the first wheel 211 and the second wheel 212, can reduce operating noise when driving the second wheel 212 to rotate. Since the power unit 210 drives the active component 221 of the transmission mechanism 220 to rotate through the second wheel 212 and provides rotational power to the transmission mechanism 220, the power unit 210 can drive the drawer box 120 to switch between the extended and retracted states through the transmission mechanism 220. Therefore, compared with the drawer using a rigid screw drive in the prior art, the noise of the drawer box 120 when extending and retracting can be reduced, thereby reducing the noise of the storage components during operation and improving the user experience.

[0086] Furthermore, the first wheel 211 is connected to the second wheel 212 to form a deceleration structure, thereby enabling the rotational speed of the first wheel 211 to be greater than that of the driving wheel. This effectively amplifies the torque of the driving component 221, making the transmission mechanism 220 operate more stably, reducing the shaking and vibration of the transmission mechanism 220 during operation, thereby reducing the noise of the transmission mechanism 220 during operation, and further reducing the noise of the register component during operation.

[0087] The first wheel 211 and the second wheel 212 of the power unit 210 are softly connected to buffer the rigid impact during transmission and absorb the vibration of the first wheel 211 and the second wheel 212 during transmission, thereby reducing the noise of the first wheel 211 and the second wheel 212 when transmitting power. This allows the power unit 210 to reduce operating noise when driving the second wheel 212 to rotate. The first wheel 211 drives the driving element 221 of the transmission mechanism 220 to rotate through the second wheel 212, so that the transmission mechanism 220 drives the drawer box 120 to be in the extended state and in the retracted state. The switching between states reduces noise during the extension and retraction of the drawer box 120 compared to drawers using rigid screw drives in existing technologies, thereby reducing noise in the storage components and improving the user experience. Furthermore, the connection between the first wheel 211 and the second wheel 212 to form a deceleration structure effectively amplifies the torque of the driving component 221, making the transmission mechanism 220 operate more stably and reducing vibration and jitter during operation, thus reducing noise in the transmission mechanism 220 and further reducing noise in the storage components.

[0088] Reference Figure 2 , Figure 3 and Figure 4In some embodiments of the present invention, the transmission mechanism 220 further includes a first gear 222, a first rack 223, and a transmission gear 224; the driving member 221 is a second gear 225, which is fixedly mounted on the second wheel 212 and is coaxial with and rotates synchronously with the second wheel 212. The second gear 225 and the second wheel 212 have the same angular velocity. The first rack 223 is mounted on the drawer box 120 and its length direction is arranged along the first direction X. The first gear 222 can mesh with the first rack 223. The transmission gear 224 can drive the first gear 222 to rotate. In this embodiment, the transmission gear 224 is coaxial with and rotates synchronously with the first gear 222. The transmission gear 224 and the first gear 222 have the same angular velocity. The outer diameter of the transmission gear 224 is larger than the outer diameter of the first gear 222. The second gear 225 can mesh with the transmission gear 224. In this embodiment, both the first gear 222 and the transmission gear 224 are rotatably connected to the housing frame 110, allowing them to rotate. The outer diameter of the first gear 222 is smaller than that of the transmission gear 224, resulting in a lower linear velocity for the first gear 222 compared to the transmission gear 224. The second gear 225 rotates the first gear 222 via the transmission gear 224, further reducing the linear velocity of the first gear 222 compared to the second gear 225. Thus, the second gear 225, transmission gear 224, and first gear 222 form a reduction gear mechanism. This, combined with the reduction damping structure of the first wheel 211 and the second wheel 212, forms a two-stage reduction mechanism. This significantly reduces the rotational speed of the first gear 222 meshing with the first rack 223, making the meshing transmission between the first gear 222 and the first rack 223 more stable. This reduces the vibration generated when the first gear 222 rotates, decreases the noise from rigid collisions, and further reduces the noise from the first gear 222 driving the first rack 223 to slide along the first direction X. Since the first rack 223 is mounted on the drawer box 120, when the first rack 223 slides along the first direction X, the corresponding drawer box 120 also slides along with the first rack 223. Therefore, the noise of the drawer box 120 extending and retracting along the first direction X can be reduced, and the noise of the storage component during operation can be further reduced.

[0089] It is understood that in this embodiment, the first gear 222 and the first rack 223 drive the drawer box 120 to extend and retract in the first direction X. Therefore, by adjusting the rotation direction of the first gear 222, the drawer box 120 can be driven to move forward or backward. In addition, the transmission mechanism 220 can also be a crank-rocker mechanism, a crank-slider mechanism, a cam-slider mechanism, or other mechanisms that can convert rotational motion into linear motion.

[0090] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the power unit 210 further includes a transmission belt 213 and a motor 214. The transmission belt 213 is wrapped around the outside of the first wheel 211 and the second wheel 212 to achieve a soft connection between the first wheel 211 and the second wheel 212. The first wheel 211 drives the second wheel 212 to rotate through the transmission belt 213. The motor 214 is connected to the first wheel 211 and is used to drive the first wheel 211 to rotate. The outer diameter of the first wheel 211 is smaller than the outer diameter of the second wheel 212. The first wheel 211, the second wheel 212, and the transmission belt 213 form a belt drive. When the first wheel 211 rotates, it can drive the second wheel 212 to rotate through the transmission belt 213, thereby allowing the first wheel 211 to transmit power to the second wheel 212, so that the second wheel 212 drives the second gear 225 to rotate. The use of a transmission belt 213 to connect the first wheel 211 and the second wheel 212 can reduce the rigid collision between the first wheel 211 and the second wheel 212. Moreover, when the transmission mechanism 220 is jammed or the drawer box 120 is jammed by external force, the motor 214 can still rotate normally, reducing the loss caused by the motor 214 being stuck due to the jamming of the external structure and extending the service life of the storage components. Furthermore, since the outer diameter of the first wheel 211 is smaller than that of the second wheel 212, the angular velocity of the second wheel 212 is smaller than that of the first wheel 211. Consequently, the angular velocity of the second gear 225 is smaller than that of the first wheel 211, thereby reducing the linear velocity of the second gear 225. This makes the rotation of the second gear 225 more stable and effectively amplifies the torque of the motor 214 on the second gear 225, better driving the drawer box 120 to slide along the first direction X. This makes the operation of the transmission mechanism 220 more stable, reducing the shaking and vibration of the transmission mechanism 220 during operation, thereby reducing the noise of the transmission mechanism 220 during operation, and further reducing the noise of the register components during operation.

[0091] In addition, in some special embodiments, chains, timing belts, etc. can be used to achieve a soft connection between the first wheel 211 and the second wheel 212.

[0092] In some embodiments of the present invention, reference is made to... Figure 5 and Figure 20 To facilitate better sliding of the drawer box 120 in the first direction X and reduce vibration, the drawer box 120 is provided with a guide groove 125 extending parallel to the first direction X, and the box frame 110 is provided with a guide block 113 for inserting into the guide groove 125. The guide block 113 prevents the drawer box 120 from shifting in the second direction Y when sliding along the first direction X, ensuring that the drawer box 120 can slide more stably along the first direction X.

[0093] In some embodiments of the present invention, reference is made to... Figure 19 The drawer box 120 has a first limiting block 126 on its bottom outer side, and the box frame 110 has a second limiting block 114 on its bottom inner side. The first limiting block 126 cooperates with the second limiting block 114 to limit the distance the drawer box 120 extends forward. The first limiting block 126 and the second limiting block 114 can be configured as a snap-fit. When the drawer box 120 extends forward to its extended state, the first limiting block 126 abuts against the second limiting block 114 to prevent the drawer box 120 from extending further forward, thereby limiting the distance the drawer box 120 extends forward and preventing the drawer box 120 from falling out of the box frame 110.

[0094] In some embodiments of the present invention, reference is made to... Figure 16 and Figure 20 The drawer box 120 has a detection through hole 127 at its bottom, and the box frame 110 has a detection sensor 115 located below the detection through hole 127. The detection through hole 127 is used to detect whether the drawer box 120 is carrying stored items, so as to feed back the electrical signal to the control system of the storage cabinet, which facilitates the control of the storage cabinet to control the overall storage process.

[0095] This embodiment also provides a storage cabinet, which includes: storage components as described above and a cabinet body. The storage components are disposed on the cabinet body, and the number of storage components can be set according to actual needs.

[0096] The storage components of the locker utilize the cooperation of a first rack 223, a first gear 222, a self-locking slider 310, and a second rack 312 on the self-locking slider 310. The power unit 210 drives the first gear 222 to rotate via the active component 221, allowing the drawer box 120 to switch between a retracted state and an extended state. Furthermore, when the self-locking slider 310 moves along a predetermined path, it enables the drawer box 120 to self-lock in the retracted state, ensuring that stored items are not lost. Compared to existing solutions that use lead screws to drive drawer movement, this embodiment eliminates the need to manufacture high-precision, high-speed lead screws, thus reducing costs. Moreover, when the motor malfunctions, an emergency unlocking tool can be inserted into the emergency channel 116 for emergency unlocking. Without forcibly removing the drawer or opening the entire locker, the malfunctioning drawer box 120 can be pulled out to retrieve the user's items, thereby reducing after-sales maintenance time and ensuring that users can retrieve their items more quickly.
