[0028] Example 1

[0029] like Figures 1 to 6 As shown, a storage cabinet in the first aspect embodiment of the present invention includes a cabinet body 1, a drawer 6, an electromagnetic mechanical lock 8 and a drive assembly 9, wherein the drawer 6 is slidably disposed inside the cabinet body 1.

[0030] The drive assembly 9 includes a motor 10, a lead screw 11, a lead screw nut 12, a first bearing 13, and a first bearing housing 16. The motor 10 is housed inside the cabinet 1. The lead screw 11 is located at the bottom of the drawer 6 along the sliding direction of the drawer 6. One end of the lead screw 11 is connected to the motor 10, and the other end of the lead screw 11 is rotatably mounted inside the cabinet 1. Specifically, a mounting base is provided inside the cabinet 1, and the end of the lead screw 11 facing away from the motor 10 is rotatably connected to the mounting base. The lead screw nut 12 is connected to the lead screw 11. The first bearing 13 is sleeved on the outside of the lead screw nut 12, and the inner ring of the first bearing 13 is connected to the lead screw nut 12. The first bearing 13 is mounted inside the first bearing housing 16. The seat 16 is installed at the bottom of the drawer 6. Preferably, the first bearing 13 is a damping bearing, which can prevent the lead screw 11 from rotating and causing the lead screw nut 12 and the inner ring of the first bearing 13 to rotate in place. During use, the torque of the motor 10 is insufficient to overcome the damping of the first bearing 13. The motor 10 can only drive the lead screw nut 12 (as well as the first bearing 13 and the first bearing seat 16) to move along the lead screw 11. The drawer 6 is relatively light in weight and can be smoothly driven to move along the lead screw 11 by the lead screw nut 12. When the drawer 6 is manually pulled open, only a larger force is needed to overcome the damping of the first bearing 13 to drive the lead screw nut 12 to rotate and move along the lead screw, thereby opening the drawer 6.

[0031] The electromagnetic mechanical lock 8 is used to lock the drawer 6 inside the cabinet 1. Specifically, the electromagnetic mechanical lock 8 can be opened by electromagnetic and mechanical keys. The electromagnetic mechanical lock 8 is in a locked state after power is cut off, thereby preventing the drawer 6 from being opened at will after power is cut off.

[0032] In this embodiment, it should be noted that the lead screw 11 and lead screw nut 12 are preferably ball screw structures. Ball screws have no self-locking function and can enable the drawer 6 to be opened manually. When the lead screw 11 and lead screw nut 12 are hydrostatic screw structures, a suitable helix angle needs to be selected so that the self-locking force can be overcome when the drawer 6 is opened manually. Slide rails 7 are provided on both sides of the sliding direction of the drawer 6, and the slide rails 7 are slidably connected to the cabinet body 1.

[0033] Furthermore, it also includes a control panel, which is located outside the cabinet 1 and is connected to the motor 10 and the electromagnetic mechanical lock 8. The control panel is used to control the operation of the motor 10 and the opening and closing of the electromagnetic mechanical lock 8.

[0034] The technical effects achieved by this embodiment are as follows: A drive assembly 9 is provided, and a motor 10 and a lead screw 11 work together. By controlling the forward and reverse rotation of the motor 10, the drawer 6 can be electrically opened and closed. By setting a first bearing 13 and a first bearing seat 16, when a power outage occurs, the electromagnetic mechanical lock 8 can be manually opened with a key, and the drawer 6 can be pulled outwards, causing the lead screw nut 12 to rotate and move along the lead screw 11 (at this time, the first bearing 13 and the first bearing seat 16 work together and will not affect the rotation and movement of the lead screw nut 12), thus manually opening the drawer 6. After the entire storage cabinet is powered off, the drawer 6 can be manually opened normally, making it safer and more reliable.

[0035] Example 2

[0036] like Figures 1 to 6 As shown, another storage cabinet provided in this embodiment has the same structure as that in Embodiment 1. Only the different parts are described below.

[0037] In this embodiment, the drawer 6 has a panel 2 on the outward side, and a handle 3 on the outer side of the panel 2. By providing the handle 3, the drawer 6 can be easily pulled out.

[0038] In this embodiment, it should be noted that the drive assembly 9 also includes a second bearing 14, a third bearing 15, a second bearing seat 17, and a third bearing seat 18. The second bearing 14 and the third bearing 15 are respectively disposed at both ends of the lead screw 11. The second bearing 14, the third bearing 15, and the lead screw 11 are coaxial. The third bearing 15 of the second bearing 14 is respectively installed in the second bearing seat 17 and the third bearing seat 18. The second bearing seat 17 and the third bearing seat 18 are both installed in the cabinet 1.

[0039] The drive assembly 9 also includes a mounting base 19, which has mounting holes. The motor 10 is mounted on the mounting base 19, which is located inside the cabinet 1.

[0040] Example 3

[0041] like Figures 1 to 6 As shown, another storage cabinet provided in this embodiment has the same structure as that in Embodiment 1. Only the different parts are described below.

[0042] In this embodiment, the back of the cabinet 1 is provided with a back panel 4, which is detachably connected to the cabinet 1. Specifically, the back panel 4 and the cabinet 1 are connected by bolts.

[0043] In this embodiment, it should be noted that the electromagnetic mechanical lock 8 is located on the side of the drawer 6 facing the back plate 4. The back plate 4 is provided with a lock hole 5, which is provided in correspondence with the mechanical lock hole 5 of the electromagnetic mechanical lock 8. After inserting the corresponding key into the lock hole 5, the electromagnetic mechanical lock 8 can be opened with the key.

[0044] Example 4

[0045] like Figures 1 to 6 As shown, another storage cabinet provided in this embodiment has the same structure as that in Embodiment 1. Only the different parts are described below.

[0046] In this embodiment, there are multiple drawers 6, and each drawer 6 is equipped with an electromagnetic mechanical lock 8 and a drive assembly 9.

[0047] In this embodiment, it should be noted that the multiple drawers 6 can be arranged in different ways, specifically, as follows: Figures 1 to 4 As shown, when set as a single-row vertical cabinet, multiple drawers 6 are arranged parallel to each other along the height direction of the cabinet body 1 to form a single-row structure; when set as a single-row horizontal cabinet, multiple drawers 6 are arranged along the length direction of the cabinet body 1 to form a single-row structure; when set as a multi-row multi-column cabinet, multiple drawers 6 are arranged in a rectangular array to form a multi-row multi-column structure.

[0048] The technical effect achieved by this embodiment is that there are multiple drawers 6, which can be set in various distribution structures to meet different usage needs and have a wider range of applications.

[0049] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0050] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
